Doctors treat osteoporosis with hormone therapy against guidelines
This type of hormone therapy (HT) can be given as estrogen or a combination of hormones including estrogen. The physicians interviewed for this piece who prescribe HT for osteoporosis suggest the benefits outweigh the downsides to its use for some of their patients. But such doctors may be a minority group, suggests Michael R. McClung, MD, founding director of the Oregon Osteoporosis Center, Portland.
According to Dr. McClung, HT is now rarely prescribed as treatment – as opposed to prevention – for osteoporosis in the absence of additional benefits such as reducing vasomotor symptoms.
Researchers’ findings on HT use in women with osteoporosis are complex. While HT is approved for menopausal prevention of osteoporosis, it is not indicated as a treatment for the disease by the Food and Drug Administration. See the prescribing information for Premarin tablets, which contain a mixture of estrogen hormones, for an example of the FDA’s indications and usage for the type of HT addressed in this article.
Women’s Health Initiative findings
The Women’s Health Initiative (WHI) hormone therapy trials showed that HT reduces the incidence of all osteoporosis-related fractures in postmenopausal women, even those at low risk of fracture, but osteoporosis-related fractures was not a study endpoint. These trials also revealed that HT was associated with increased risks of cardiovascular and cerebrovascular events, an increased risk of breast cancer, and other adverse health outcomes.
The release of the interim results of the WHI trials in 2002 led to a fair amount of fear and confusion about the use of HT after menopause. After the WHI findings were published, estrogen use dropped dramatically, but for everything, including for vasomotor symptoms and the prevention and treatment of osteoporosis.
Prior to the WHI study, it was very common for hormone therapy to be prescribed as women neared or entered menopause, said Risa Kagan MD, clinical professor of obstetrics, gynecology, and reproductive sciences, University of California, San Francisco.
“When a woman turned 50, that was one of the first things we did – was to put her on hormone therapy. All that changed with the WHI, but now we are coming full circle,” noted Dr. Kagan, who currently prescribes HT as first line treatment for osteoporosis to some women.
Hormone therapy’s complex history
HT’s ability to reduce bone loss in postmenopausal women is well-documented in many papers, including one published March 8, 2018, in Osteoporosis International, by Dr. Kagan and colleagues. This reduced bone loss has been shown to significantly reduce fractures in patients with low bone mass and osteoporosis.
While a growing number of therapies are now available to treat osteoporosis, HT was traditionally viewed as a standard method of preventing fractures in this population. It was also widely used to prevent other types of symptoms associated with the menopause, such as hot flashes, night sweats, and sleep disturbances, and multiple observational studies had demonstrated that its use appeared to reduce the incidence of cardiovascular disease (CVD) in symptomatic menopausal women who initiated HT in early menopause.
Even though the WHI studies were the largest randomized trials ever performed in postmenopausal women, they had notable limitations, according to Dr. Kagan.
“The women were older – the average age was 63 years,” she said. “And they only investigated one route and one dose of estrogen.”
Since then, many different formulations and routes of administration with more favorable safety profiles than what was used in the WHI have become available.
It’s both scientifically and clinically unsound to extrapolate the unfavorable risk-benefit profile of HT seen in the WHI trials to all women regardless of age, HT dosage or formulation, or the length of time they’re on it, she added.
Today’s use of HT in women with osteoporosis
Re-analyses and follow-up studies from the WHI trials, along with data from other studies, have suggested that the benefit-risk profiles of HT are affected by a variety of factors. These include the timing of use in relation to menopause and chronological age and the type of hormone regimen.
“Clinically, many advocate for [hormone therapy] use, especially in the newer younger postmenopausal women to prevent bone loss, but also in younger women who are diagnosed with osteoporosis and then as they get older transition to more bone specific agents,” noted Dr. Kagan.
“Some advocate preserving bone mass and preventing osteoporosis and even treating the younger newly postmenopausal women who have no contraindications with hormone therapy initially, and then gradually transitioning them to a bone specific agent as they get older and at risk for fracture.
“If a woman is already fractured and/or has very low bone density with no other obvious secondary metabolic reason, we also often advocate anabolic agents for 1-2 years then consider estrogen for maintenance – again, if [there is] no contraindication to using HT,” she added.
Thus, an individualized approach is recommended to determine a woman’s risk-benefit ratio of HT use based on the absolute risk of adverse effects, Dr. Kagan noted.
“Transdermal and low/ultra-low doses of HT, have a favorable risk profile, and are effective in preserving bone mineral density and bone quality in many women,” she said.
According to Dr. McClung, HT “is most often used for treatment in women in whom hormone therapy was begun for hot flashes and then, when osteoporosis was found later, was simply continued.
“Society guidelines are cautious about recommending hormone therapy for osteoporosis treatment since estrogen is not approved for treatment, despite the clear fracture protection benefit observed in the WHI study,” he said. “Since [women in the WHI trials] were not recruited as having osteoporosis, those results do not meet the FDA requirement for treatment approval, namely the reduction in fracture risk in patients with osteoporosis. However, knowing what we know about the salutary skeletal effects of estrogen, many of us do use them in our patients with osteoporosis – although not prescribed for that purpose.”
Additional scenarios when doctors may advise HT
“I often recommend – and I think colleagues do as well – that women with recent menopause and menopausal symptoms who also have low bone mineral density or even scores showing osteoporosis see their gynecologist to discuss HT for a few years, perhaps until age 60 if no contraindications, and if it is well tolerated,” said Ethel S. Siris, MD, professor of medicine at Columbia University Medical Center in New York.
“Once they stop it we can then give one of our other bone drugs, but it delays the need to start them since on adequate estrogen the bone density should remain stable while they take it,” added Dr. Siris, an endocrinologist and internist, and director of the Toni Stabile Osteoporosis Center in New York. “They may need a bisphosphonate or another bone drug to further protect them from bone loss and future fracture [after stopping HT].”
Victor L. Roberts, MD, founder of Endocrine Associates of Florida, Lake Mary, pointed out that women now have many options for treatment of osteoporosis.
“If a woman is in early menopause and is having other symptoms, then estrogen is warranted,” he said. “If she has osteoporosis, then it’s a bonus.”
“We have better agents that are bone specific,” for a patient who presents with osteoporosis and no other symptoms, he said.
“If a woman is intolerant of alendronate or other similar drugs, or chooses not to have an injectable, then estrogen or a SERM [selective estrogen receptor modulator] would be an option.”
Dr. Roberts added that HT would be more of a niche drug.
“It has a role and documented benefit and works,” he said. “There is good scientific data for the use of estrogen.”

Doctors have failed them, say those with transgender regret
In a unique Zoom conference,
The forum was convened on what was dubbed #DetransitionAwarenessDay by Genspect, a parent-based organization that seeks to put the brakes on medical transitions for children and adolescents. The group has doubts about the gender-affirming care model supported by the World Professional Association for Transgender Health, the American Medical Association, the American Academy of Pediatrics, and other medical groups.
“Affirmative” medical care is defined as treatment with puberty blockers and cross-sex hormones for those with gender dysphoria to transition to the opposite sex and is often followed by gender reassignment surgery. However, there is growing concern among many doctors and other health care professionals as to whether this is, in fact, the best way to proceed for those under aged 18, in particular, with several countries pulling back on medical treatment and instead emphasizing psychotherapy first.
The purpose of the second annual Genspect meeting was to shed light on the experiences of individuals who have detransitioned – those that identified as transgender and transitioned, but then decided to end their medical transition. People logged on from all over the United States, Canada, New Zealand, Australia, the United Kingdom, Germany, Spain, Chile, and Brazil, among other countries.
“This is a minority within a minority,” said Genspect advisor Stella O’Malley, adding that the first meeting in 2021 was held because “too many people were dismissing the stories of the detransitioners.” Ms. O’Malley is a psychotherapist, a clinical advisor to the Society for Evidence-Based Gender Medicine, and a founding member of the International Association of Therapists for Desisters and Detransitioners.
“It’s become blindingly obvious over the last year that ... ‘detrans’ is a huge part of the trans phenomenon,” said Ms. O’Malley, adding that detransitioners have been “undermined and dismissed.”
Laura Edwards-Leeper, PhD (@DrLauraEL), a prominent gender therapist who has recently expressed concern regarding adequate gatekeeping when treating youth with gender dysphoria, agreed.
She tweeted: “You simply can’t call yourself a legit gender provider if you don’t believe that detransitioners exist. As part of the informed consent process for transitioning, it is unethical to not discuss this possibility with young people.” Dr. Edwards-Leeper is professor emeritus at Pacific University in Hillsboro, Ore.
Speakers in the forum largely offered experiences, not data. They pointed out that there has been little to no study of detransition, but all testified that it was less rare than it has been portrayed by the transgender community.
Struggles with going back
“There are so many reasons why people detransition,” said Sinead Watson, aged 30, a Genspect advisor who transitioned from female to male, starting in 2015, and who decided to detransition in 2019. Citing a study by Lisa Littman, MD, MPH, published in 2021, Ms. Watson said the most common reasons for detransitioning were realizing that gender dysphoria was caused by other issues; internal homophobia; and the unbearable nature of transphobia.
Ms. Watson said the hardest part of detransitioning was admitting to herself that her transition had been a mistake. “It’s embarrassing and you feel ashamed and guilty,” she said, adding that it may mean losing friends who now regard you as a “bigot, while you’re also dealing with transition regret.”
“It’s a living hell, especially when none of your therapists or counselors will listen to you,” she said. “Detransitioning isn’t fun.”
Carol (@sourpatches2077) said she knew for a year that her transition had been a mistake.
“The biggest part was I couldn’t tell my family,” said Carol, who identifies as a lesbian. “I put them through so much. It seems ridiculous to go: ‘Oops, I made this huge [expletive] mistake,’ ” she said, describing the moment she did tell them as “devastating.”
Grace (@hormonehangover) said she remembers finally hitting a moment of “undeniability” some years after transitioning. “I accept it, I’ve ruined my life, this is wrong,” she remembers thinking. “It was devastating, but I couldn’t deny it anymore.”
Don’t trust therapists
People experiencing feelings of unease “need a therapist who will listen to them,” said Ms. Watson. When she first detransitioned, her therapists treated her badly. “They just didn’t want to speak about detransition,” she said, adding that “it was like a kick in the stomach.”
Ms. Watson said she’d like to see more training about detransition, but also on “preventative techniques,” adding that many people transition who should not. “I don’t want more detransitioners – I want less.
“In order for that to happen, we need to treat people with gender dysphoria properly,” said Ms. Watson, adding that the affirmative model is “disgusting, and that’s what needs to change.”
“I would tell somebody to not go to a therapist,” said Carol. Identifying as a butch lesbian, she felt like her therapists had pushed her into transitioning to male. “The No. 1 thing not understood by the mental health professionals is that the vast majority of homosexuals were gender-nonconforming children.” She added that this is especially true of butch lesbians.
Therapists – and doctors – also need to acknowledge both the trauma of transition and detransition, she said.
Kaiser, where she had transitioned, offered her breast reconstruction. Carol said it felt demeaning. “Like you’re Mr. Potatohead: ‘Here, we can just ... put on some new parts and you’re good to go.’ ”
“Doctors are concretizing transient obsessions,” said Helena Kerschner (@lacroicsz), quoting a chatroom user.
Ms. Kerschner gave a presentation on “fandom”: becoming obsessed with a movie, book, TV show, musician, or celebrity, spending every waking hour chatting online or writing fan fiction, or attempting to interact with the celebrity online. It’s a fantasy-dominated world and “the vast majority” of participants are teenage girls who are “identifying as trans,” in part, because they are fed a community-reinforced message that it’s better to be a boy.
Therapists and physicians who help them transition “are harming them for life based on something they would have grown out of or overcome without the permanent damage,” Ms. Kerschner added.
Doctors ‘gaslighting’ people into believing that transition is the answer
A pervasive theme during the webinar was that many people are being misdiagnosed with gender dysphoria, which may not be resolved by medical transition.
Allie, a 22-year-old who stopped taking testosterone after 1½ years, said she initially started the transition to male when she gave up trying to figure out why she could not identify with, or befriend, women, and after a childhood and adolescence spent mostly in the company of boys and being more interested in traditionally male activities.
She endured sexual abuse as a teenager and her parents divorced while she was in high school. Allie also had multiple suicide attempts and many incidents of self-harm. When she decided to transition, at age 18, she went to a private clinic and received cross-sex hormones within a few months of her first and only 30-minute consultation. “There was no explorative therapy,” she said, adding that she was never given a formal diagnosis of gender dysphoria.
For the first year, she said she was “over the freaking moon” because she felt like it was the answer. But things started to unravel while she attended university, and she attempted suicide attempt at age 20. A social worker at the school identified her symptoms – which had been the same since childhood – as autism. She then decided to cease her transition.
Another detransitioner, Laura Becker, said it took 5 years after her transition to recognize that she had undiagnosed PTSD from emotional and psychiatric abuse. Despite a history of substance abuse, self-harm, suicidal ideation, and other mental health issues, she was given testosterone and had a double mastectomy at age 20. She became fixated on gay men, which devolved into a methamphetamine- and crack-fueled relationship with a man she met on the gay dating platform Grindr.
“No one around me knew any better or knew how to help, including the medical professionals who performed the mastectomy and who casually signed off and administered my medical transition,” she said.
Once she was aware of her PTSD she started to detransition, which itself was traumatic, said Laura.
Limpida, aged 24, said he felt pushed into transitioning after seeking help at a Planned Parenthood clinic. He identified as trans at age 15 and spent years attempting to be a woman socially, but every step made him feel more miserable, he said. When he went to the clinic at age 21 to get estrogen, he said he felt like the staff was dismissive of his mental health concerns – including that he was suicidal, had substance abuse, and was severely depressed. He was told he was the “perfect candidate” for transitioning.
A year later, he said he felt worse. The nurse suggested he seek out surgery. After Limpida researched what was involved, he decided to detransition. He has since received an autism diagnosis.
Robin, also aged 24, said the idea of surgery had helped push him into detransitioning, which began in 2020 after 4 years of estrogen. He said he had always been gender nonconforming and knew he was gay at an early age. He believes that gender-nonconforming people are “gaslighted” into thinking that transitioning is the answer.
Lack of evidence-based, informed consent
Michelle Alleva, who stopped identifying as transgender in 2020 but had ceased testosterone 4 years earlier because of side effects, cited what she called a lack of evidence base for the effectiveness and safety of medical transitions.
“You need to have a really, really good evidence base in place if you’re going straight to an invasive treatment that is going to cause permanent changes to your body,” she said.
Access to medical transition used to involve more “gatekeeping” through mental health evaluations and other interventions, she said, but there has been a shift from treating what was considered a psychiatric issue to essentially affirming an identity.
“This shift was activist driven, not evidence based,” she emphasized.
Most studies showing satisfaction with transition only involve a few years of follow-up, she said. She added that the longest follow-up study of transition, published in 2011 and spanning 30 years, showed that the suicide rate 10-15 years post surgery was 20 times higher than the general population.
Studies of regret were primarily conducted before the rapid increase in the number of trans-identifying individuals, she said, which makes it hard to draw conclusions about pediatric transition. Getting estimates on this population is difficult because so many who detransition do not tell their clinicians, and many studies have short follow-up times or a high loss to follow-up.
Ms. Alleva also took issue with the notion that physicians were offering true informed consent, noting that it’s not possible to know if someone is psychologically sound if they haven’t had a thorough mental health evaluation and that there are so many unknowns with medical transition, including that many of the therapies are not approved for the uses being employed.
With regret on the rise, “we need professionals that are prepared for detransitioners,” said Ms. Alleva. “Some of us have lost trust in health care professionals as a result of our experience.”
“It’s a huge feeling of institutional betrayal,” said Grace.

As part of the informed consent process for transitioning, it is unethical to not discuss this possibility with young people.” Dr. Edwards-Leeper is professor emeritus at Pacific University in Hillsboro, Ore.
Speakers in the forum largely offered experiences, not data. They pointed out that there has been little to no study of detransition, but all testified that it was less rare than it has been portrayed by the transgender community.
Struggles with going back
“There are so many reasons why people detransition,” said Sinead Watson, aged 30, a Genspect advisor who transitioned from female to male, starting in 2015, and who decided to detransition in 2019. Citing a study by Lisa Littman, MD, MPH, published in 2021, Ms. Watson said the most common reasons for detransitioning were realizing that gender dysphoria was caused by other issues; internal homophobia; and the unbearable nature of transphobia.
Ms. Watson said the hardest part of detransitioning was admitting to herself that her transition had been a mistake. “It’s embarrassing and you feel ashamed and guilty,” she said, adding that it may mean losing friends who now regard you as a “bigot, while you’re also dealing with transition regret.”
“It’s a living hell, especially when none of your therapists or counselors will listen to you,” she said. “Detransitioning isn’t fun.”
Carol (@sourpatches2077) said she knew for a year that her transition had been a mistake.
“The biggest part was I couldn’t tell my family,” said Carol, who identifies as a lesbian. “I put them through so much. It seems ridiculous to go: ‘Oops, I made this huge [expletive] mistake,’ ” she said, describing the moment she did tell them as “devastating.”
Grace (@hormonehangover) said she remembers finally hitting a moment of “undeniability” some years after transitioning. “I accept it, I’ve ruined my life, this is wrong,” she remembers thinking. “It was devastating, but I couldn’t deny it anymore.”
Don’t trust therapists
People experiencing feelings of unease “need a therapist who will listen to them,” said Ms. Watson. When she first detransitioned, her therapists treated her badly. “They just didn’t want to speak about detransition,” she said, adding that “it was like a kick in the stomach.”
Ms. Watson said she’d like to see more training about detransition, but also on “preventative techniques,” adding that many people transition who should not. “I don’t want more detransitioners – I want less.
“In order for that to happen, we need to treat people with gender dysphoria properly,” said Ms. Watson, adding that the affirmative model is “disgusting, and that’s what needs to change.”
“I would tell somebody to not go to a therapist,” said Carol. Identifying as a butch lesbian, she felt like her therapists had pushed her into transitioning to male. “The No. 1 thing not understood by the mental health professionals is that the vast majority of homosexuals were gender-nonconforming children.” She added that this is especially true of butch lesbians.
Therapists – and doctors – also need to acknowledge both the trauma of transition and detransition, she said.
Kaiser, where she had transitioned, offered her breast reconstruction. Carol said it felt demeaning. “Like you’re Mr. Potatohead: ‘Here, we can just ... put on some new parts and you’re good to go.’ ”
“Doctors are concretizing transient obsessions,” said Helena Kerschner (@lacroicsz), quoting a chatroom user.
Ms. Kerschner gave a presentation on “fandom”: becoming obsessed with a movie, book, TV show, musician, or celebrity, spending every waking hour chatting online or writing fan fiction, or attempting to interact with the celebrity online. It’s a fantasy-dominated world and “the vast majority” of participants are teenage girls who are “identifying as trans,” in part, because they are fed a community-reinforced message that it’s better to be a boy.
Therapists and physicians who help them transition “are harming them for life based on something they would have grown out of or overcome without the permanent damage,” Ms. Kerschner added.
Doctors ‘gaslighting’ people into believing that transition is the answer
A pervasive theme during the webinar was that many people are being misdiagnosed with gender dysphoria, which may not be resolved by medical transition.
Allie, a 22-year-old who stopped taking testosterone after 1½ years, said she initially started the transition to male when she gave up trying to figure out why she could not identify with, or befriend, women, and after a childhood and adolescence spent mostly in the company of boys and being more interested in traditionally male activities.
She endured sexual abuse as a teenager and her parents divorced while she was in high school. Allie also had multiple suicide attempts and many incidents of self-harm. When she decided to transition, at age 18, she went to a private clinic and received cross-sex hormones within a few months of her first and only 30-minute consultation. “There was no explorative therapy,” she said, adding that she was never given a formal diagnosis of gender dysphoria.
For the first year, she said she was “over the freaking moon” because she felt like it was the answer. But things started to unravel while she attended university, and she attempted suicide attempt at age 20. A social worker at the school identified her symptoms – which had been the same since childhood – as autism. She then decided to cease her transition.
Another detransitioner, Laura Becker, said it took 5 years after her transition to recognize that she had undiagnosed PTSD from emotional and psychiatric abuse. Despite a history of substance abuse, self-harm, suicidal ideation, and other mental health issues, she was given testosterone and had a double mastectomy at age 20. She became fixated on gay men, which devolved into a methamphetamine- and crack-fueled relationship with a man she met on the gay dating platform Grindr.
“No one around me knew any better or knew how to help, including the medical professionals who performed the mastectomy and who casually signed off and administered my medical transition,” she said.
Once she was aware of her PTSD she started to detransition, which itself was traumatic, said Laura.
Limpida, aged 24, said he felt pushed into transitioning after seeking help at a Planned Parenthood clinic. He identified as trans at age 15 and spent years attempting to be a woman socially, but every step made him feel more miserable, he said. When he went to the clinic at age 21 to get estrogen, he said he felt like the staff was dismissive of his mental health concerns – including that he was suicidal, had substance abuse, and was severely depressed. He was told he was the “perfect candidate” for transitioning.
A year later, he said he felt worse. The nurse suggested he seek out surgery. After Limpida researched what was involved, he decided to detransition. He has since received an autism diagnosis.
Robin, also aged 24, said the idea of surgery had helped push him into detransitioning, which began in 2020 after 4 years of estrogen. He said he had always been gender nonconforming and knew he was gay at an early age. He believes that gender-nonconforming people are “gaslighted” into thinking that transitioning is the answer.
Lack of evidence-based, informed consent
Michelle Alleva, who stopped identifying as transgender in 2020 but had ceased testosterone 4 years earlier because of side effects, cited what she called a lack of evidence base for the effectiveness and safety of medical transitions.
“You need to have a really, really good evidence base in place if you’re going straight to an invasive treatment that is going to cause permanent changes to your body,” she said.
Access to medical transition used to involve more “gatekeeping” through mental health evaluations and other interventions, she said, but there has been a shift from treating what was considered a psychiatric issue to essentially affirming an identity.
“This shift was activist driven, not evidence based,” she emphasized.
Most studies showing satisfaction with transition only involve a few years of follow-up, she said. She added that the longest follow-up study of transition, published in 2011 and spanning 30 years, showed that the suicide rate 10-15 years post surgery was 20 times higher than the general population.
Studies of regret were primarily conducted before the rapid increase in the number of trans-identifying individuals, she said, which makes it hard to draw conclusions about pediatric transition. Getting estimates on this population is difficult because so many who detransition do not tell their clinicians, and many studies have short follow-up times or a high loss to follow-up.
Ms. Alleva also took issue with the notion that physicians were offering true informed consent, noting that it’s not possible to know if someone is psychologically sound if they haven’t had a thorough mental health evaluation and that there are so many unknowns with medical transition, including that many of the therapies are not approved for the uses being employed.
With regret on the rise, “we need professionals that are prepared for detransitioners,” said Ms. Alleva. “Some of us have lost trust in health care professionals as a result of our experience.”
“It’s a huge feeling of institutional betrayal,” said Grace.

In a unique Zoom conference,
The forum was convened on what was dubbed #DetransitionAwarenessDay by Genspect, a parent-based organization that seeks to put the brakes on medical transitions for children and adolescents. The group has doubts about the gender-affirming care model supported by the World Professional Association for Transgender Health, the American Medical Association, the American Academy of Pediatrics, and other medical groups.
“Affirmative” medical care is defined as treatment with puberty blockers and cross-sex hormones for those with gender dysphoria to transition to the opposite sex and is often followed by gender reassignment surgery. However, there is growing concern among many doctors and other health care professionals as to whether this is, in fact, the best way to proceed for those under aged 18, in particular, with several countries pulling back on medical treatment and instead emphasizing psychotherapy first.
The purpose of the second annual Genspect meeting was to shed light on the experiences of individuals who have detransitioned – those that identified as transgender and transitioned, but then decided to end their medical transition. People logged on from all over the United States, Canada, New Zealand, Australia, the United Kingdom, Germany, Spain, Chile, and Brazil, among other countries.
“This is a minority within a minority,” said Genspect advisor Stella O’Malley, adding that the first meeting in 2021 was held because “too many people were dismissing the stories of the detransitioners.” Ms. O’Malley is a psychotherapist, a clinical advisor to the Society for Evidence-Based Gender Medicine, and a founding member of the International Association of Therapists for Desisters and Detransitioners.
“It’s become blindingly obvious over the last year that ... ‘detrans’ is a huge part of the trans phenomenon,” said Ms. O’Malley, adding that detransitioners have been “undermined and dismissed.”
Laura Edwards-Leeper, PhD (@DrLauraEL), a prominent gender therapist who has recently expressed concern regarding adequate gatekeeping when treating youth with gender dysphoria, agreed.

Is cancer testing going to the dogs? Nope, ants
The oncologist’s new best friend
We know that dogs have very sensitive noses. They can track criminals and missing persons and sniff out drugs and bombs. They can even detect cancer cells … after months of training.
And then there are ants.
Cancer cells produce volatile organic compounds (VOCs), which can be sniffed out by dogs and other animals with sufficiently sophisticated olfactory senses. A group of French investigators decided to find out if Formica fusca is such an animal.
First, they placed breast cancer cells and healthy cells in a petri dish. The sample of cancer cells, however, included a sugary treat. “Over successive trials, the ants got quicker and quicker at finding the treat, indicating that they had learned to recognize the VOCs produced by the cancerous cells, using these as a beacon to guide their way to the sugary delight,” according to IFL Science.
When the researchers removed the treat, the ants still went straight for the cancer cells. Then they removed the healthy cells and substituted another type of breast cancer cell, with just one type getting the treat. They went for the cancer cells with the treat, “indicating that they were capable of distinguishing between the different cancer types based on the unique pattern of VOCs emitted by each one,” IFL Science explained.
It’s just another chapter in the eternal struggle between dogs and ants. Dogs need months of training to learn to detect cancer cells; ants can do it in 30 minutes. Over the course of a dog’s training, Fido eats more food than 10,000 ants combined. (Okay, we’re guessing here, but it’s got to be a pretty big number, right?)
Then there’s the warm and fuzzy factor. Just look at that picture. Who wouldn’t want a cutie like that curling up in the bed next to you?
Console War II: Battle of the Twitter users
Video games can be a lot of fun, provided you’re not playing something like Rock Simulator. Or Surgeon Simulator. Or Surgeon Simulator 2. Yes, those are all real games. But calling yourself a video gamer invites a certain negative connotation, and nowhere can that be better exemplified than the increasingly ridiculous console war.
For those who don’t know their video game history, back in the early 90s Nintendo and Sega were the main video game console makers. Nintendo had Mario, Sega had Sonic, and everyone had an opinion on which was best. With Sega now but a shell of its former self and Nintendo viewed as too “casual” for the true gaming connoisseur, today’s battle pits Playstation against Xbox, and fans of both consoles spend their time trying to one-up each other in increasingly silly online arguments.
That brings us nicely to a Twitter user named “Shreeveera,” who is very vocal about his love of Playstation and hatred of the Xbox. Importantly, for LOTME purposes, Shreeveera identified himself as a doctor on his profile, and in the middle of an argument, Xbox enthusiasts called his credentials into question.
At this point, most people would recognize that there are very few noteworthy console-exclusive video games in today’s world and that any argument about consoles essentially comes down to which console design you like or which company you find less distasteful, and they would step away from the Twitter argument. Shreeveera is not most people, and he decided the next logical move was to post a video of himself and an anesthetized patient about to undergo a laparoscopic cholecystectomy.
This move did prove that he was indeed a doctor, but the ethics of posting such a video with a patient in the room is a bit dubious at best. Since Shreeveera also listed the hospital he worked at, numerous Twitter users review bombed the hospital with one-star reviews. Shreeveera’s fate is unknown, but he did take down the video and removed “doctor by profession” from his profile. He also made a second video asking Twitter to stop trying to ruin his life. We’re sure that’ll go well. Twitter is known for being completely fair and reasonable.
Use your words to gain power
We live in the age of the emoji. The use of emojis in texts and emails is basically the new shorthand. It’s a fun and easy way to chat with people close to us, but a new study shows that it doesn’t help in a business setting. In fact, it may do a little damage.
The use of images such as emojis in communication or logos can make a person seem less powerful than someone who opts for written words, according to Elinor Amit, PhD, of Tel Aviv University and associates.
Participants in their study were asked to imagine shopping with a person wearing a T-shirt. Half were then shown the logo of the Red Sox baseball team and half saw the words “Red Sox.” In another scenario, they were asked to imagine attending a retreat of a company called Lotus. Then half were shown an employee wearing a shirt with an image of lotus flower and half saw the verbal logo “Lotus.” In both scenarios, the individuals wearing shirts with images were seen as less powerful than the people who wore shirts with words on them.
Why is that? In a Eurekalert statement, Dr. Amit said that “visual messages are often interpreted as a signal for desire for social proximity.” In a world with COVID-19, that could give anyone pause.
That desire for more social proximity, in turn, equals a suggested loss of power because research shows that people who want to be around other people more are less powerful than people who don’t.
With the reduced social proximity we have these days, we may want to keep things cool and lighthearted, especially in work emails with people who we’ve never met. It may be, however, that using your words to say thank you in the multitude of emails you respond to on a regular basis is better than that thumbs-up emoji. Nobody will think less of you.
Should Daylight Savings Time still be a thing?
This past week, we just experienced the spring-forward portion of Daylight Savings Time, which took an hour of sleep away from us all. Some of us may still be struggling to find our footing with the time change, but at least it’s still sunny out at 7 pm. For those who don’t really see the point of changing the clocks twice a year, there are actually some good reasons to do so.
Sen. Marco Rubio, sponsor of a bill to make the time change permanent, put it simply: “If we can get this passed, we don’t have to do this stupidity anymore.” Message received, apparently, since the measure just passed unanimously in the Senate.
It’s not clear if President Biden will approve it, though, because there’s a lot that comes into play: economic needs, seasonal depression, and safety.
“I know this is not the most important issue confronting America, but it’s one of those issues where there’s a lot of agreement,” Sen. Rubio said.
Not total agreement, though. The National Association of Convenience Stores is opposed to the bill, and Reuters noted that one witness at a recent hearing said the time change “is like living in the wrong time zone for almost eight months out of the year.”
Many people, however, seem to be leaning toward the permanent spring-forward as it gives businesses a longer window to provide entertainment in the evenings and kids are able to play outside longer after school.
Honestly, we’re leaning toward whichever one can reduce seasonal depression.

The sample of cancer cells, however, included a sugary treat. “Over successive trials, the ants got quicker and quicker at finding the treat, indicating that they had learned to recognize the VOCs produced by the cancerous cells, using these as a beacon to guide their way to the sugary delight,” according to IFL Science.
When the researchers removed the treat, the ants still went straight for the cancer cells. Then they removed the healthy cells and substituted another type of breast cancer cell, with just one type getting the treat. They went for the cancer cells with the treat, “indicating that they were capable of distinguishing between the different cancer types based on the unique pattern of VOCs emitted by each one,” IFL Science explained.
It’s just another chapter in the eternal struggle between dogs and ants. Dogs need months of training to learn to detect cancer cells; ants can do it in 30 minutes. Over the course of a dog’s training, Fido eats more food than 10,000 ants combined. (Okay, we’re guessing here, but it’s got to be a pretty big number, right?)
Then there’s the warm and fuzzy factor. Just look at that picture. Who wouldn’t want a cutie like that curling up in the bed next to you?
Console War II: Battle of the Twitter users
Video games can be a lot of fun, provided you’re not playing something like Rock Simulator. Or Surgeon Simulator. Or Surgeon Simulator 2. Yes, those are all real games. But calling yourself a video gamer invites a certain negative connotation, and nowhere can that be better exemplified than the increasingly ridiculous console war.
For those who don’t know their video game history, back in the early 90s Nintendo and Sega were the main video game console makers. Nintendo had Mario, Sega had Sonic, and everyone had an opinion on which was best. With Sega now but a shell of its former self and Nintendo viewed as too “casual” for the true gaming connoisseur, today’s battle pits Playstation against Xbox, and fans of both consoles spend their time trying to one-up each other in increasingly silly online arguments.
That brings us nicely to a Twitter user named “Shreeveera,” who is very vocal about his love of Playstation and hatred of the Xbox. Importantly, for LOTME purposes, Shreeveera identified himself as a doctor on his profile, and in the middle of an argument, Xbox enthusiasts called his credentials into question.
At this point, most people would recognize that there are very few noteworthy console-exclusive video games in today’s world and that any argument about consoles essentially comes down to which console design you like or which company you find less distasteful, and they would step away from the Twitter argument. Shreeveera is not most people, and he decided the next logical move was to post a video of himself and an anesthetized patient about to undergo a laparoscopic cholecystectomy.
This move did prove that he was indeed a doctor, but the ethics of posting such a video with a patient in the room is a bit dubious at best. Since Shreeveera also listed the hospital he worked at, numerous Twitter users review bombed the hospital with one-star reviews. Shreeveera’s fate is unknown, but he did take down the video and removed “doctor by profession” from his profile. He also made a second video asking Twitter to stop trying to ruin his life. We’re sure that’ll go well. Twitter is known for being completely fair and reasonable.
Use your words to gain power
We live in the age of the emoji. The use of emojis in texts and emails is basically the new shorthand. It’s a fun and easy way to chat with people close to us, but a new study shows that it doesn’t help in a business setting. In fact, it may do a little damage.
The use of images such as emojis in communication or logos can make a person seem less powerful than someone who opts for written words, according to Elinor Amit, PhD, of Tel Aviv University and associates.
Participants in their study were asked to imagine shopping with a person wearing a T-shirt. Half were then shown the logo of the Red Sox baseball team and half saw the words “Red Sox.” In another scenario, they were asked to imagine attending a retreat of a company called Lotus. Then half were shown an employee wearing a shirt with an image of lotus flower and half saw the verbal logo “Lotus.” In both scenarios, the individuals wearing shirts with images were seen as less powerful than the people who wore shirts with words on them.
Why is that? In a Eurekalert statement, Dr. Amit said that “visual messages are often interpreted as a signal for desire for social proximity.” In a world with COVID-19, that could give anyone pause.
That desire for more social proximity, in turn, equals a suggested loss of power because research shows that people who want to be around other people more are less powerful than people who don’t.
With the reduced social proximity we have these days, we may want to keep things cool and lighthearted, especially in work emails with people who we’ve never met. It may be, however, that using your words to say thank you in the multitude of emails you respond to on a regular basis is better than that thumbs-up emoji. Nobody will think less of you.
Should Daylight Savings Time still be a thing?
This past week, we just experienced the spring-forward portion of Daylight Savings Time, which took an hour of sleep away from us all. Some of us may still be struggling to find our footing with the time change, but at least it’s still sunny out at 7 pm. For those who don’t really see the point of changing the clocks twice a year, there are actually some good reasons to do so.
Sen. Marco Rubio, sponsor of a bill to make the time change permanent, put it simply: “If we can get this passed, we don’t have to do this stupidity anymore.” Message received, apparently, since the measure just passed unanimously in the Senate.
It’s not clear if President Biden will approve it, though, because there’s a lot that comes into play: economic needs, seasonal depression, and safety.
“I know this is not the most important issue confronting America, but it’s one of those issues where there’s a lot of agreement,” Sen. Rubio said.
Not total agreement, though. The National Association of Convenience Stores is opposed to the bill, and Reuters noted that one witness at a recent hearing said the time change “is like living in the wrong time zone for almost eight months out of the year.”
Many people, however, seem to be leaning toward the permanent spring-forward as it gives businesses a longer window to provide entertainment in the evenings and kids are able to play outside longer after school.
Honestly, we’re leaning toward whichever one can reduce seasonal depression.
Pollution levels linked to physical and mental health problems
Other analyses of data have found environmental air pollution from sources such as car exhaust and factory output can trigger an inflammatory response in the body. What’s new about a study published in RMD Open is that it explored an association between long-term exposure to pollution and risk of autoimmune diseases, wrote Giovanni Adami, MD, of the University of Verona (Italy) and colleagues.
“Environmental air pollution, according to the World Health Organization, is a major risk to health and 99% of the population worldwide is living in places where recommendations for air quality are not met,” said Dr. Adami in an interview. The limited data on the precise role of air pollution on rheumatic diseases in particular prompted the study, he said.
To explore the potential link between air pollution exposure and autoimmune disease, the researchers reviewed medical information from 81,363 adults via a national medical database in Italy; the data were submitted between June 2016 and November 2020.
The average age of the study population was 65 years, and 92% were women; 22% had at least one coexisting health condition. Each study participant was linked to local environmental monitoring via their residential postcode.
The researchers obtained details about concentrations of particulate matter in the environment from the Italian Institute of Environmental Protection that included 617 monitoring stations in 110 Italian provinces. They focused on concentrations of 10 and 2.5 (PM10 and PM2.5).
Exposure thresholds of 30 mcg/m3 for PM10 and 20 mcg/m3 for PM2.5 are generally considered harmful to health, they noted. On average, the long-term exposure was 16 mcg/m3 for PM2.5 and 25 mcg/m3 for PM10 between 2013 and 2019.
Overall, 9,723 individuals (12%) were diagnosed with an autoimmune disease between 2016 and 2020.
Exposure to PM10 was associated with a 7% higher risk of diagnosis with any autoimmune disease for every 10 mcg/m3 increase in concentration, but no association appeared between PM2.5 exposure and increased risk of autoimmune diseases.
However, in an adjusted model, chronic exposure to PM10 above 30 mcg/m3 and to PM2.5 above 20 mcg/m3 were associated with a 12% and 13% higher risk, respectively, of any autoimmune disease.
Chronic exposure to high levels of PM10 was specifically associated with a higher risk of rheumatoid arthritis, but no other autoimmune diseases. Chronic exposure to high levels of PM2.5 was associated with a higher risk of rheumatoid arthritis, connective tissue diseases, and inflammatory bowel diseases.
In their discussion, the researchers noted that the smaller diameter of PM2.5 molecules fluctuate less in response to rain and other weather, compared with PM10 molecules, which might make them a more accurate predictor of exposure to chronic air pollution.
The study findings were limited by several factors including the observational design, which prohibits the establishment of cause, and a lack of data on the start of symptoms and dates of diagnoses for autoimmune diseases, the researchers noted. Other limitations include the high percentage of older women in the study, which may limit generalizability, and the inability to account for additional personal exposure to pollutants outside of the environmental exposure, they said.
However, the results were strengthened by the large sample size and wide geographic distribution with variable pollution exposure, they said.
“Unfortunately, we were not surprised at all,” by the findings, Dr. Adami said in an interview.
“The biological rationale underpinning our findings is strong. Nevertheless, the magnitude of the effect was overwhelming. In addition, we saw an effect even at threshold of exposure that is widely considered as safe,” Dr. Adami noted.
Clinicians have been taught to consider cigarette smoking or other lifestyle behaviors as major risk factors for the development of several autoimmune diseases, said Dr. Adami. “In the future, we probably should include air pollution exposure as a risk factor as well. Interestingly, there is also accumulating evidence linking acute exposure to environmental air pollution with flares of chronic arthritis,” he said.
“Our study could have direct societal and political consequences,” and might help direct policy makers’ decisions on addressing strategies aimed to reduce fossil emissions, he said. As for additional research, “we certainly need multination studies to confirm our results on a larger scale,” Dr. Adami emphasized. “In addition, it is time to take action and start designing interventions aimed to reduce acute and chronic exposure to air pollution in patients suffering from RMDs.”
Consider the big picture of air quality
The Italian study is especially timely “given our evolving and emerging understanding of environmental risk factors for acute and chronic diseases, which we must first understand before we can address,” said Eileen Barrett, MD, of the University of New Mexico, Albuquerque, in an interview.
“I am largely surprised about the findings, as most physicians aren’t studying ambient air quality and risk for autoimmune disease,” said Dr. Barrett. “More often we think of air quality when we think of risk for respiratory diseases than autoimmune diseases, per se,” she said.
“There are several take-home messages from this study,” said Dr. Barrett. “The first is that we need more research to understand the consequences of air pollutants on health. Second, this study reminds us to think broadly about how air quality and our environment can affect health. And third, all clinicians should be committed to promoting science that can improve public health and reduce death and disability,” she emphasized.
The findings do not specifically reflect associations between pollution and other conditions such as chronic obstructive pulmonary disease and asthma although previous studies have shown an association between asthma and COPD exacerbations and air pollution, Dr. Barrett said.
“Further research will be needed to confirm the associations reported in this study,” Dr. Barrett said.
More research in other countries, including research related to other autoimmune diseases, and with other datasets on population and community level risks from poor air quality, would be helpful, and that information could be used to advise smart public policy, Dr. Barrett added.
Air pollution’s mental health impact
Air pollution’s effects extend beyond physical to the psychological, a new study of depression in teenagers showed. This study was published in Developmental Psychology.
Previous research on the environmental factors associated with depressive symptoms in teens has focused mainly on individual and family level contributors; the impact of the physical environment has not been well studied, the investigators, Erika M. Manczak, PhD, of the University of Denver and colleagues, wrote.
In their paper, the authors found a significant impact of neighborhood ozone exposure on the trajectory of depressive symptoms in teens over a 4-year period.
“Given that inhaling pollution activates biological pathways implicated in the development of depression, including immune, cardiovascular, and neurodevelopmental processes, exposure to ambient air pollution may influence the development and/or trajectory of depressive symptoms in youth,” they said.
The researchers recruited 213 adolescents in the San Francisco Bay area through local advertisements. The participants were aged 9-13 years at baseline, with an average age of 11 years. A total of 121 were female, 47% were white, 8.5% were African American, 12.3% were Asian, 10.4% were nonwhite Latin, and 21.7% were biracial or another ethnicity. The participants self-reported depressive symptoms and other psychopathology symptoms up to three times during the study period. Ozone exposure was calculated based on home addresses.
After controlling for other personal, family, and neighborhood variables, the researchers found that higher levels of ozone exposure were significantly associated with increased depressive symptoms over time, and the slope of trajectory of depressive symptoms became steeper as the ozone levels increased (P less than .001). Ozone did not significantly predict the trajectory of any other psychopathology symptoms.
“The results of this study provide preliminary support for the possibility that ozone is an overlooked contributor to the development or course of youth depressive symptoms,” the researchers wrote in their discussion.
“Interestingly, the association between ozone and symptom trajectories as measured by Anxious/Depressed subscale of the [Youth Self-Report] was not as strong as it was for the [Children’s Depression Inventory-Short Version] or Withdrawn/Depressed scales, suggesting that associations are more robust for behavioral withdrawal symptoms of depression than for other types of symptoms,” they noted.
The study findings were limited by the use of self-reports and by the inability of the study design to show causality, the researchers said. Other limitations include the use of average assessments of ozone that are less precise, lack of assessment of biological pathways for risk, lack of formal psychiatric diagnoses, and the small geographic region included in the study, they said.
However, the results provide preliminary evidence that ozone exposure is a potential contributing factor to depressive symptoms in youth, and serve as a jumping-off point for future research, they noted. Future studies should address changes in systemic inflammation, neurodevelopment, or stress reactivity, as well as concurrent psychosocial or biological factors, and temporal associations between air pollution and mental health symptoms, they concluded.
Environmental factors drive inflammatory responses
Peter L. Loper Jr., MD, considers the findings of the Developmental Psychology study to be unsurprising but important – because air pollution is simply getting worse.
“As the study authors cite, there is sufficient data correlating ozone to negative physical health outcomes in youth, but a paucity of data exploring the impact of poor air quality on mental health outcomes in this demographic,” noted Dr. Loper, of the University of South Carolina, Columbia, in an interview.
“As discussed by the study researchers, any environmental exposure that increases immune-mediated inflammation can result in negative health outcomes. In fact, there is already data to suggest that similar cytokines, or immune cell signalers, that get released by our immune system due to environmental exposures and that contribute to asthma, may also be implicated in depression and other mental health problems,” he noted.
“Just like downstream symptom indicators of physical illnesses such as asthma are secondary to immune-mediated pulmonary inflammation, downstream symptom indicators of mental illness, such as depression, are secondary to immune-mediated neuroinflammation,” Dr. Loper emphasized. “The most well-characterized upstream phenomenon perpetuating the downstream symptom indicators of depression involve neuroinflammatory states due to psychosocial and relational factors such as chronic stress, poor relationships, or substance use. However, any environmental factor that triggers an immune response and inflammation can promote neuroinflammation that manifests as symptoms of mental illness.”
The message for teens with depression and their families is that “we are a product of our environment,” Dr. Loper said. “When our environments are proinflammatory, or cause our immune system to become overactive, then we will develop illness; however, the most potent mediator of inflammation in the brain, and the downstream symptoms of depression, is our relationships with those we love most,” he said.
Dr. Loper suggested research aimed at identifying other sources of immune-mediated inflammation caused by physical environments and better understanding how environmental phenomenon like ozone may compound previously established risk factors for mental illness could be useful.
The RMD Open study received no outside funding, and its authors had no financial conflicts.
The Developmental Psychology study was supported by the National Institute of Mental Health and the Stanford University Precision Health and Integrated Diagnostics Center. The researchers for that report, and Dr. Loper and Dr. Barrett had no conflicts to disclose.

A total of 121 were female, 47% were white, 8.5% were African American, 12.3% were Asian, 10.4% were nonwhite Latin, and 21.7% were biracial or another ethnicity. The participants self-reported depressive symptoms and other psychopathology symptoms up to three times during the study period. Ozone exposure was calculated based on home addresses.
After controlling for other personal, family, and neighborhood variables, the researchers found that higher levels of ozone exposure were significantly associated with increased depressive symptoms over time, and the slope of trajectory of depressive symptoms became steeper as the ozone levels increased (P less than .001). Ozone did not significantly predict the trajectory of any other psychopathology symptoms.
“The results of this study provide preliminary support for the possibility that ozone is an overlooked contributor to the development or course of youth depressive symptoms,” the researchers wrote in their discussion.
“Interestingly, the association between ozone and symptom trajectories as measured by Anxious/Depressed subscale of the [Youth Self-Report] was not as strong as it was for the [Children’s Depression Inventory-Short Version] or Withdrawn/Depressed scales, suggesting that associations are more robust for behavioral withdrawal symptoms of depression than for other types of symptoms,” they noted.
The study findings were limited by the use of self-reports and by the inability of the study design to show causality, the researchers said. Other limitations include the use of average assessments of ozone that are less precise, lack of assessment of biological pathways for risk, lack of formal psychiatric diagnoses, and the small geographic region included in the study, they said.
However, the results provide preliminary evidence that ozone exposure is a potential contributing factor to depressive symptoms in youth, and serve as a jumping-off point for future research, they noted. Future studies should address changes in systemic inflammation, neurodevelopment, or stress reactivity, as well as concurrent psychosocial or biological factors, and temporal associations between air pollution and mental health symptoms, they concluded.
Environmental factors drive inflammatory responses
Peter L. Loper Jr., MD, considers the findings of the Developmental Psychology study to be unsurprising but important – because air pollution is simply getting worse.
“As the study authors cite, there is sufficient data correlating ozone to negative physical health outcomes in youth, but a paucity of data exploring the impact of poor air quality on mental health outcomes in this demographic,” noted Dr. Loper, of the University of South Carolina, Columbia, in an interview.
“As discussed by the study researchers, any environmental exposure that increases immune-mediated inflammation can result in negative health outcomes. In fact, there is already data to suggest that similar cytokines, or immune cell signalers, that get released by our immune system due to environmental exposures and that contribute to asthma, may also be implicated in depression and other mental health problems,” he noted.
“Just like downstream symptom indicators of physical illnesses such as asthma are secondary to immune-mediated pulmonary inflammation, downstream symptom indicators of mental illness, such as depression, are secondary to immune-mediated neuroinflammation,” Dr. Loper emphasized. “The most well-characterized upstream phenomenon perpetuating the downstream symptom indicators of depression involve neuroinflammatory states due to psychosocial and relational factors such as chronic stress, poor relationships, or substance use. However, any environmental factor that triggers an immune response and inflammation can promote neuroinflammation that manifests as symptoms of mental illness.”
The message for teens with depression and their families is that “we are a product of our environment,” Dr. Loper said. “When our environments are proinflammatory, or cause our immune system to become overactive, then we will develop illness; however, the most potent mediator of inflammation in the brain, and the downstream symptoms of depression, is our relationships with those we love most,” he said.
Dr. Loper suggested research aimed at identifying other sources of immune-mediated inflammation caused by physical environments and better understanding how environmental phenomenon like ozone may compound previously established risk factors for mental illness could be useful.
The RMD Open study received no outside funding, and its authors had no financial conflicts.
The Developmental Psychology study was supported by the National Institute of Mental Health and the Stanford University Precision Health and Integrated Diagnostics Center. The researchers for that report, and Dr. Loper and Dr. Barrett had no conflicts to disclose.

Navigating patient requests for an emotional support animal
When Serena-Lian Sakheim-Devine’s best friend from childhood died of cancer, she felt sad and lonely while away at college. Wanting something warm to snuggle, she got a guinea pig and named her Basil. Then she got two more and called them Nutmeg and Paprika. The three became her Spice Girls.
“They were of great comfort to me, but also to others at times of need,” said Ms. Sakheim-Devine, 26, who lived with them in a dormitory at Smith College, an all-women’s institution in Northampton, Mass.
Her therapist wrote a letter and sent it to the disability office at Smith, which permitted the guinea pigs as emotional support animals (ESAs). Eventually, though, she wanted a dog to help manage her PTSD, depression, anxiety, and panic attacks. So, she adopted a beagle from a shelter.
Once again, a therapist provided a letter, and Ms. Sakheim-Devine was allowed to keep the beagle, Finnian, then about 13 years old, in her dorm room on the condition that she give up the guinea pigs, which she did.
She and Finnian bonded almost instantly. When she woke up drenched in sweat, unable to move or speak, the dog sensed how tense she was. Finnian licked her hands, got her fingers moving, and helped ground her.
“I didn’t really teach her that. She just knew,” said Ms. Sakheim-Devine, now a safety engineer who lives in New Haven, Conn. “It was incredible how well connected we were, even from the get-go.”
The therapeutic benefits of four-legged friends
Although there is limited scientific literature on the therapeutic use of ESAs, there are well-established benefits of having pets that also apply in these situations. Animals can provide distraction from stress, alleviate loneliness, and instill a sense of responsibility, said Rachel A. Davis, MD, associate professor of psychiatry and neurosurgery at the University of Colorado at Denver, Aurora.
They add structure to a person’s day by needing to be fed at specific times, and they can help the human get exercise. “Patients have reported improved sense of meaning in life and purpose,” Dr. Davis said.
Examples include depression, anxiety, obsessive-compulsive disorder, panic attacks, and PTSD.
ESAs differ from psychiatric service animals, which are trained to perform specific tasks, such as applying deep pressure that calms the owner. By their mere existence, ESAs provide emotional benefits to a person with a mental health disability.
“Social support, even from an animal, can really help people feel less alone, better about themselves, and safer from unpleasantness or even a physical attack,” said David Spiegel, MD, professor and associate chair of psychiatry and behavioral sciences and director of the Center on Stress and Health at Stanford (Calif.) University.
Writing a letter on your patient’s behalf
Writing a letter that serves as proof of a person’s need for an ESA is a request that mental health professionals sometimes receive from patients. The letter can grant access to housing without additional cost regardless of no-pet polices, and some employers may allow an ESA at work as a reasonable accommodation for a psychological disability. Until recently, an ESA could accompany its owner on a plane, but most airlines no longer permit this, partly because some passengers falsely claim their pets as ESAs.
Before crafting a letter for someone with an ESA, Dr. Spiegel asks for the patient’s permission to elaborate on the clinical condition that merits professional help and to explain how the animal relieves associated symptoms.
The Fair Housing Act, a federal law, requires a landlord to grant a reasonable accommodation involving an emotional support or other assistance animal. Such an accommodation honors a request to live on the property despite a no-pets policy. It also waives a pet deposit, fee, or other rules involving animals on the premises.
Landlords are usually supportive of a request to permit an ESA, said Jonathan Betlinski, MD, associate professor and director of the public psychiatry division at Oregon Health and Science University, Portland. None of his patients have experienced any difficulties once they obtained a letter from him.
However, “anytime somebody asks me about a letter for an ESA, that’s the time to have a conversation. It’s not automatic,” Dr. Betlinski said. The discussion involves learning about the type of animal a patient has and how it helps his or her emotional state.
Because of privacy concerns, Dr. Betlinski doesn’t disclose the specific diagnosis in the letter unless the patient signs a release of information. The laws pertaining to ESAs only require his letter to note that an individual has a qualifying diagnosis and that an ESA helps improve symptoms, but it’s not necessary to explain how.
“You can see where writing the letter is a fine balancing act,” he said. But he finds it helpful to mention any training the animal has completed, such as the Canine Good Citizen course sponsored by the American Kennel Club.
Most of the letters Luis Anez, PsyD, a clinical psychologist and associate professor of psychiatry at Yale University, New Haven, Conn., has written for this purpose were in support of ESAs in housing. But he also recalled providing a letter for a patient who was flying to Puerto Rico with an ESA. The letters are generally provided only to established patients with psychiatric diagnoses.
Without a letter, “we’ve seen people say: ‘I’d rather be homeless than part with my dog,’ ”said Dr. Anez, who is also director of Hispanic services at Connecticut Mental Health Center in New Haven, a partnership between Yale and the Connecticut Department of Mental Health and Addiction Services. Before getting an ESA, Dr. Anez recommends that individuals become aware of their landlord’s policies on possible restrictions relating to dog sizes and breeds.
Additional considerations
An ESA doesn’t necessarily have to be a dog. “It certainly could be a cat. It could be a parrot, too,” said Stephen Stern, MD, a psychiatrist in private practice in Mount Kisco, N.Y. But, “if they say that their emotional support animal is an earthworm, that would make you wonder,” he added half-jokingly.
Dr. Stern only writes an ESA letter for a patient with whom he has an ongoing professional relationship. For instance, if he’s treating someone for depression and that patient tells him how the animal helps relieve symptoms, then that is sufficient justification to write a letter.
“Because you know them, you’ve assessed that what they’re saying is plausible,” said Dr. Stern, who is also an adjunct professor of psychiatry at the University of Texas Health Science in San Antonio, where he conducted research on companion dogs for veterans with PTSD and continues to collaborate with colleagues via email and Zoom.
While veterans benefit from ESAs, some live in housing that doesn’t permit animals, said Beth Zimmerman, founder and executive director of Pets for Patriots, a nationally operating nonprofit organization in Long Beach, N.Y., that partners with shelters and animal welfare groups to adopt dogs and cats for companionship and emotional support. She said an ESA can be “a wonderful complement to other forms of therapy that a veteran may undertake.
“Most of the time when the veteran encounters a problem, it’s because the landlord is ill-informed of the law,” Dr. Zimmerman said. “We provide information to the veteran to share with the landlord or building management, and always recommend taking a very amicable approach. In our experience, with very few exceptions, once the landlord understands his or her responsibilities under the law, they will permit the veteran to have that emotional support animal in their dwelling.”
For Kristin Lowe, a chocolate Labrador-Weimaraner mix named Lola provided emotional support from her puppy days until her death at age 12 in May 2021. Ms. Lowe’s psychiatrist provided letters that allowed Lola to live in her apartment and to travel on commercial airline flights.
“She was so connected to me,” said Ms. Lowe, 34, who lives in Denver and works as an administrative office worker in physical therapy. “She was a part of me. She could read every emotion that I had.”
Now, Ms. Lowe relies on Henry, an Australian shepherd puppy, to help her cope with obsessive-compulsive disorder, major depressive disorder, and an eating disorder. She described him as “a very happy little guy and a constant tail wagger – and that lights up something in me.”

Study: Majority of research on homeopathic remedies unpublished or unregistered
Homeopathy is a form of alternative medicine based on the concept that increasing dilution of a substance leads to a stronger treatment effect.
The authors of the new paper, published in BMJ Evidence-Based Medicine, also found that a quarter of the 90 randomized published trials on homeopathic remedies they analyzed changed their results before publication.
The benefits of homeopathy touted in studies may be greatly exaggerated, suggest the authors, Gerald Gartlehner, MD, of Danube University, Krems, Austria, and colleagues.
The results raise awareness that published homeopathy trials represent a limited proportion of research, skewed toward favorable results, they wrote.
“This likely affects the validity of the body of evidence of homeopathic literature and may substantially overestimate the true treatment effect of homeopathic remedies,” they concluded.
Homeopathy as practiced today was developed approximately 200 years ago in Germany, and despite ongoing debate about its effectiveness, it remains a popular alternative to conventional medicine in many developed countries, the authors noted.
According to the National Institutes of Health, homeopathy is based on the idea of “like cures like,” meaning that a disease can be cured with a substance that produces similar symptoms in healthy people, and the “law of minimum dose,” meaning that a lower dose of medication will be more effective. “Many homeopathic products are so diluted that no molecules of the original substance remain,” according to the NIH.
Homeopathy is not subject to most regulatory requirements, so assessment of effectiveness of homeopathic remedies is limited to published data, the researchers said. “When no information is publicly available about the majority of homeopathic trials, sound conclusions about the efficacy and the risks of using homeopathic medicinal products for treating health conditions are impossible,” they wrote.
Study methods and findings
The researchers examined 17 trial registries for studies involving homeopathic remedies conducted since 2002.
The registries included clinicaltrials.gov, the EU Clinical Trials Register, and the International Clinical Trials Registry Platform up to April 2019 to identify registered homeopathy trials.
To determine whether registered trials were published and to identify trials that were published but unregistered, the researchers examined PubMed, the Allied and Complementary Medicine Database, Embase, and Google Scholar up to April 2021.
They found that approximately 38% of registered trials of homeopathy were never published, and 53% of the published randomized, controlled trials (RCTs) were not registered. Notably, 25% of the trials that were registered and published showed primary outcomes that were changed compared with the registry.
The number of registered homeopathy trials increased significantly over the past 5 years, but approximately one-third (30%) of trials published during the last 5 years were not registered, they said. In a meta-analysis, unregistered RCTs showed significantly greater treatment effects than registered RCTs, with standardized mean differences of –0.53 and –0.14, respectively.
The study findings were limited by several factors including the potential for missed records of studies not covered by the registries searched. Other limitations include the analysis of pooled data from homeopathic treatments that may not generalize to personalized homeopathy, and the exclusion of trials labeled as terminated or suspended.
Proceed with caution before recommending use of homeopathic remedies, says expert
Linda Girgis, MD, noted that prior to reading this report she had known that most homeopathic remedies didn’t have any evidence of being effective, and that, therefore, the results validated her understanding of the findings of studies of homeopathy.
The study is especially important at this time in the wake of the COVID-19 pandemic, Dr. Girgis, a family physician in private practice in South River, N.J., said in an interview.
“Many people are promoting treatments that don’t have any evidence that they are effective, and more people are turning to homeopathic treatments not knowing the risks and assuming they are safe,” she continued. “Many people are taking advantage of this and trying to cash in on this with ill-proven remedies.”
Homeopathic remedies become especially harmful when patients think they can use them instead of traditional medicine, she added.
Noting that some homeopathic remedies have been studied and show some evidence that they work, Dr. Girgis said there may be a role for certain ones in primary care.
“An example would be black cohosh or primrose oil for perimenopausal hot flashes. This could be a good alternative when you want to avoid hormonal supplements,” she said.
At the same time, Dr. Girgis advised clinicians to be cautious about suggesting homeopathic remedies to patients.
“Homeopathy seems to be a good money maker if you sell these products. However, you are not protected from liability and can be found more liable for prescribing off-label treatments or those not [Food and Drug Administration] approved,” Dr. Girgis said. Her general message to clinicians: Stick with evidence-based medicine.
Her message to patients who might want to pursue homeopathic remedies is that just because something is “homeopathic” or natural doesn’t mean that it is safe.
“There are some [homeopathic] products that have caused liver damage or other problems,” she explained. “Also, these remedies can interact with other medications.”
The study received no outside funding. The researchers and Dr. Girgis had no financial conflicts to disclose.

The registries included clinicaltrials.gov, the EU Clinical Trials Register, and the International Clinical Trials Registry Platform up to April 2019 to identify registered homeopathy trials.
To determine whether registered trials were published and to identify trials that were published but unregistered, the researchers examined PubMed, the Allied and Complementary Medicine Database, Embase, and Google Scholar up to April 2021.
They found that approximately 38% of registered trials of homeopathy were never published, and 53% of the published randomized, controlled trials (RCTs) were not registered. Notably, 25% of the trials that were registered and published showed primary outcomes that were changed compared with the registry.
The number of registered homeopathy trials increased significantly over the past 5 years, but approximately one-third (30%) of trials published during the last 5 years were not registered, they said. In a meta-analysis, unregistered RCTs showed significantly greater treatment effects than registered RCTs, with standardized mean differences of –0.53 and –0.14, respectively.
The study findings were limited by several factors including the potential for missed records of studies not covered by the registries searched. Other limitations include the analysis of pooled data from homeopathic treatments that may not generalize to personalized homeopathy, and the exclusion of trials labeled as terminated or suspended.
Proceed with caution before recommending use of homeopathic remedies, says expert
Linda Girgis, MD, noted that prior to reading this report she had known that most homeopathic remedies didn’t have any evidence of being effective, and that, therefore, the results validated her understanding of the findings of studies of homeopathy.
The study is especially important at this time in the wake of the COVID-19 pandemic, Dr. Girgis, a family physician in private practice in South River, N.J., said in an interview.
“Many people are promoting treatments that don’t have any evidence that they are effective, and more people are turning to homeopathic treatments not knowing the risks and assuming they are safe,” she continued. “Many people are taking advantage of this and trying to cash in on this with ill-proven remedies.”
Homeopathic remedies become especially harmful when patients think they can use them instead of traditional medicine, she added.
Noting that some homeopathic remedies have been studied and show some evidence that they work, Dr. Girgis said there may be a role for certain ones in primary care.
“An example would be black cohosh or primrose oil for perimenopausal hot flashes. This could be a good alternative when you want to avoid hormonal supplements,” she said.
At the same time, Dr. Girgis advised clinicians to be cautious about suggesting homeopathic remedies to patients.
“Homeopathy seems to be a good money maker if you sell these products. However, you are not protected from liability and can be found more liable for prescribing off-label treatments or those not [Food and Drug Administration] approved,” Dr. Girgis said. Her general message to clinicians: Stick with evidence-based medicine.
Her message to patients who might want to pursue homeopathic remedies is that just because something is “homeopathic” or natural doesn’t mean that it is safe.
“There are some [homeopathic] products that have caused liver damage or other problems,” she explained. “Also, these remedies can interact with other medications.”
The study received no outside funding. The researchers and Dr. Girgis had no financial conflicts to disclose.
Homeopathy is a form of alternative medicine based on the concept that increasing dilution of a substance leads to a stronger treatment effect.
The authors of the new paper, published in BMJ Evidence-Based Medicine, also found that a quarter of the 90 randomized published trials on homeopathic remedies they analyzed changed their results before publication.
The benefits of homeopathy touted in studies may be greatly exaggerated, suggest the authors, Gerald Gartlehner, MD, of Danube University, Krems, Austria, and colleagues.
The results raise awareness that published homeopathy trials represent a limited proportion of research, skewed toward favorable results, they wrote.
“This likely affects the validity of the body of evidence of homeopathic literature and may substantially overestimate the true treatment effect of homeopathic remedies,” they concluded.
Homeopathy as practiced today was developed approximately 200 years ago in Germany, and despite ongoing debate about its effectiveness, it remains a popular alternative to conventional medicine in many developed countries, the authors noted.
According to the National Institutes of Health, homeopathy is based on the idea of “like cures like,” meaning that a disease can be cured with a substance that produces similar symptoms in healthy people, and the “law of minimum dose,” meaning that a lower dose of medication will be more effective. “Many homeopathic products are so diluted that no molecules of the original substance remain,” according to the NIH.
Homeopathy is not subject to most regulatory requirements, so assessment of effectiveness of homeopathic remedies is limited to published data, the researchers said. “When no information is publicly available about the majority of homeopathic trials, sound conclusions about the efficacy and the risks of using homeopathic medicinal products for treating health conditions are impossible,” they wrote.

‘Bigorexia’: Why teenage boys are obsessed with bulking up
Why are teenage boys obsessed with bulking up?
While the effects of Instagram on girls’ body image has long been documented – an article in The Wall Street Journal that was published this fall reported that Facebook knew Instagram was toxic for teen girls – teenage boys are under just as much pressure.
For adolescent boys, the goal is often to get superhero-size buff – and this is leading to anxiety, stress, excessive selfies, and, often, obsessive staring in the mirror to assess their “pec” progress.
So-called “bigorexia” – or extreme gym time, excessive focus on protein diets, and intense muscle-building goals – has hit new and concerning levels, according to a recent New York Times report.
Whether it’s the pandemic or TikTok that’s to blame, teen boys are pushing hard to achieve six-pack abs, with one-third of them in the U.S. trying to bulk up, according to a study published in the Journal of Adolescent Health. What’s more, 22% reported they’re engaging in muscle-enhancing behavior, including excess exercise, taking supplements or steroids, or eating more to bulk up, according to a study published in the International Journal of Eating Disorders.
“The pandemic and social media have been a perfect storm for eating disorders and body image issues for all teens, but this has been under-recognized in boys,” says Jason Nagata, MD, a pediatrician who specializes in adolescent medicine at the University of California, San Francisco. “Both are directly connected to an increase in muscle dysmorphia.”
While “bigorexia” is a newer term coined by mental health professionals, the concept of muscular dysmorphia isn’t, says Jennifer Bahrman, PhD, a licensed psychologist with McGovern Medical School at UTHealth Houston. This may be why about a third of boys ages 11-18 reported that they aren’t enamored with their bodies, according to a small survey published in 2019 in the Californian Journal of Health Promotion.
“When we think of dysmorphia, we think of girls having it, since we see it more in females,” says Dr. Bahrman, who works extensively with adolescents and athletes. “The interesting thing about muscular dysmorphia is that it’s the only body dysmorphic disorder that’s almost exclusively present in males.”
Social media’s role
Unlike other things in boys’ lives, like movies, TV, or even the uber-buff GI Joe doll, social media has created opportunities for young men to put their bodies on display – and become an influencer or get followers because of it.
“An everyday teen can become a celebrity,” Dr. Nagata says. “Then, thanks to social media algorithms, if a teenage boy likes or interacts with a post that features a muscular guy or is all about fitness, they’ll start getting all sorts of related content. They’ll get bombarded with tons of ads for protein shakes, for example, as well as bodybuilding equipment, and that will further distort reality.”
Before-and-after photos are also known to be quite misleading.
“Some of the most popular Instagram posts among teens feature people who have experienced a massive body transformation,” Dr. Nagata says. “It’s usually someone who lost a lot of weight or someone who was scrawny and then got muscular. The most drastic changes tend to get the most likes and are perpetuated the most and shared the most often with friends.”
But as many are aware, photos posted to social media are selected to tell the best story – with the best filters, lighting, and angles possible, however exaggerated.
“A guy will post his worst picture out of a thousand for his before shot and then post the best photo out of a thousand,” Dr. Nagata says. “This, in itself, can really confuse a teenager, because the story of this person’s changed body looks so realistic.”
Worse, these images tend to be damaging to your teenager’s self-esteem.
“When you see images of people you’re aspiring to look like, it can be very upsetting,” Dr. Bahrman says. “After all, it’s easy to think, ‘I’m doing all of these pushups, and I don’t look like this.’ From there, it’s easy to begin internalizing that something is wrong with you.”
Red flags to watch out for
If you’ve noticed that your son is obsessed with his appearance, weight, food, or exercise, take note. Also, notice if he’s asking you to buy protein powder or is spending more time at the gym than with his friends.
“Pay attention if he is withdrawing from friends and family because of his concerns about his appearance,” Dr. Nagata says. “For example, we often hear that a teenager will no longer eat family meals or at a restaurant because the protein content isn’t high enough or the food is too fatty.”
If you’re concerned, always make sure to discuss this with your son’s pediatrician.
“Ultimately, you want to make sure you share your concerns before your teen son becomes even more body-image obsessed,” Dr. Nagata says.

Children and COVID: Decline in new cases reaches 7th week
New cases of COVID-19 in U.S. children have fallen to their lowest level since the beginning of the Delta surge in July of 2021, according to the American Academy of Pediatrics and the Children’s Hospital Association.
. Over those 7 weeks, new cases dropped over 96% from the 1.15 million reported for Jan. 14-20, based on data collected by the AAP and CHA from state and territorial health departments.
The last time that the weekly count was below 42,000 was July 16-22, 2021, when almost 39,000 cases were reported in the midst of the Delta upsurge. That was shortly after cases had reached their lowest point, 8,447, since the early stages of the pandemic in 2020, the AAP/CHA data show.
The cumulative number of pediatric cases is now up to 12.7 million, while the overall proportion of cases occurring in children held steady at 19.0% for the 4th week in a row, the AAP and CHA said in their weekly COVID-19 report. The Centers for Disease Control and Prevention, using an age range of 0-18 versus the states’ variety of ages, puts total cases at 11.7 million and deaths at 1,656 as of March 14.
Data from the CDC’s COVID-19–Associated Hospitalization Surveillance Network show that hospitalizations with laboratory-confirmed infection were down by 50% in children aged 0-4 years, by 63% among 5- to 11-year-olds, and by 58% in those aged 12-17 years for the week of Feb. 27 to March 5, compared with the week before.
The pace of vaccination continues to follow a similar trend, as the declines seen through February have continued into March. Cumulatively, 33.7% of children aged 5-11 have received at least one dose, and 26.8% are fully vaccinated, with corresponding numbers of 68.0% and 58.0% for children aged 12-17, the CDC reported on its COVID Data Tracker.
State-level data show that children aged 5-11 in Vermont, with a rate of 65%, are the most likely to have received at least one dose of COVID vaccine, while just 15% of 5- to 11-year-olds in Alabama, Louisiana, and Mississippi have gotten their first dose. Among children aged 12-17, that rate ranges from 40% in Wyoming to 94% in Hawaii, Massachusetts, and Rhode Island, the AAP said in a separate report based on CDC data.
In a recent report involving 1,364 children aged 5-15 years, two doses of the COVID-19 vaccine reduced the risk of infection from the Omicron variant by 31% in children aged 5-11 years and by 59% among children aged 12-15 years, said Ashley L. Fowlkes, ScD, of the CDC’s COVID-19 Emergency Response Team, and associates (MMWR 2022 Mar 11;71).

Inside insulin (Part 2): Approaching a cure for type 1 diabetes?
Editor’s note: This is the second in a two-part series commemorating the 100-year anniversary of the first use of insulin in humans. Part 1 of this series examined the rivalry behind the discovery and use of insulin.
One hundred years ago, teenager Leonard Thompson was the first patient with type 1 diabetes to be successfully treated with insulin, granting him a reprieve from what was a certain death sentence at the time.
Since then, research has gathered pace. In the century since insulin’s discovery and first use, recombinant DNA technology has allowed for the engineering of the insulin molecule, providing numerous short- and long-acting analog versions. At the same time, technological leaps in automated insulin delivery and monitoring of blood glucose ensure more time with glucose in range and fewer life-threatening complications for those with type 1 diabetes fortunate enough to have access to the technology.
In spite of these advancements, there is still scope for further evolution of disease management, with the holy grail being the transplant of stem cell–derived islet cells capable of making insulin, ideally encased in some kind of protective device so that immunosuppression is not required.
Indeed, it is not unreasonable to “hope that type 1 diabetes will be a curable disease in the next 100 years,” said Elizabeth Stephens, MD, an endocrinologist who has type 1 diabetes and practices in Portland, Ore.
Type 1 diabetes: The past 100 years
The epidemiology of type 1 diabetes has shifted considerably since 1922. A century ago, given that average life expectancy in the United States was around 54 years, it was pretty much the only type of diabetes that doctors encountered. “There was some type 2 diabetes about in heavier people, but the focus was on type 1 diabetes,” noted Dr. Stephens.
Originally called juvenile diabetes because it was thought to only occur in children, “now 50% of people are diagnosed with type 1 diabetes ... over [the age of] 20,” explained Dr. Stephens.
In the United States, around 1.4 million adults 20 years and older, and 187,000 children younger than 20, have the disease, according to data from the National Diabetes Statistics Report 2020 by the Centers for Disease Control and Prevention. This total represents an increase of nearly 30% from 2017.
Over the years, theories as to the cause, or trigger, for type 1 diabetes “have included cow’s milk and [viral] infections,” said Dr. Stephens. “Most likely, there’s a genetic predisposition and some type of exposure, which creates the perfect storm to trigger disease.”
There are hints that COVID-19 might be precipitating type 1 diabetes in some people. Recently, the CDC found SARS-CoV-2 infection was associated with an increased risk for diabetes (all types) among youth, but not other acute respiratory infections. And two further studies from different parts of the world have recently identified an increase in the incidence of type 1 diabetes in children since the COVID-19 pandemic began, but the reasons remain unclear.
The global CoviDiab registry has also been established to collect data on patients with COVID-19–related diabetes.
The million-dollar question: Is COVID-19 itself is propagating type 1 diabetes or unmasking a predisposition to the disease sooner? The latter might be associated with a lower type 1 diabetes rate in the future, said Partha Kar, MBBS, OBE, national specialty advisor, diabetes, for National Health Service England.
“Right now, we don’t know the answer. Whichever way you look at it, it is likely there will be a rise in cases, and in countries where insulin is not freely available, healthcare systems need to have supply ready because insulin is lifesaving in type 1 diabetes,” Dr. Kar emphasized.
CGMs and automated insulin delivery: A ‘godsend’
A huge change has also been seen, most notably in the past 15 to 20 years, in the technological advancements that can help those with type 1 diabetes live an easier life.
Continuous glucose monitors (CGMs) and automated ways of delivering insulin, such as smart pens and insulin pumps, have made the daily life of a person with type 1 diabetes in the Western world considerably more comfortable.
CGMs provide a constant stream of data to an app, often wirelessly in sync with the insulin pump. However, on a global level, they are only available to a lucky few.
In England, pending National Institute for Health and Care Excellence) approval, any CGM should be available to all eligible patients with type 1 diabetes within the NHS from April 2022, Dr. Kar pointed out. In the United States, CGMs are often unaffordable and access is mostly dependent on a person’s health insurance.
Kersten Hall, PhD, a scientist and U.K.-based medical historian who recently wrote a book, “Insulin, the Crooked Timber” (Oxford, England: Oxford University Press, 2022) uncovering the lesser-known story behind the discovery of insulin, was diagnosed with adult-onset type 1 diabetes at the age of 41. Dr. Hall had always found the finger-prick blood glucose test to be a chore but now has a CGM.
“It’s a total game changer for me: a godsend. I can’t sing its praises enough,” he said. “All it involves is the swipe of the phone and this provides a reading which tells me if my glucose is too low, so I eat something, or too high, so I might [go for] a run.”
Brewing insulin at scale
As described by Dr. Hall in his book, the journey from treating Mr. Thompson in 1922 to treating the masses began when biochemist James Collip, MD, PhD, discovered a means of purifying the animal pancreas extracts used to treat the teenager.
But production at scale presented a further challenge. This was overcome in 1924 when Eli Lilly drew on a technique used in the beer brewing process – where pH guides bitterness – to purify and manufacture large amounts of insulin.
By 1936, a range of slower-acting cattle and pig-derived insulins, the first produced by Novo Nordisk Pharmaceuticals, were developed.
However, it took 8,000 lb (approximately 3,600 kg) of pancreas glands from 23,500 animals to make 1 lb (0.5 kg) of insulin, so a more efficient process was badly needed.
Dr. Hall, who is a molecular biologist as well as an author, explains that the use of recombinant DNA technology to produce human insulin, as done by Genentech in the late 70s, was a key development in the story of modern insulin products. Genentech then provided synthetic human insulin for Eli Lilly to conduct clinical trials.
Human insulin most closely resembles porcine insulin structure and function, differing by only one amino acid, while human insulin differs from bovine insulin by three amino acid residues. This synthetic human insulin eliminated the allergies that the animal-derived products sometimes caused.
In the early 1980s, Eli Lilly produced Humulin, the first biosynthetic (made in Escherichia coli, hence the term, “bio”) human insulin.
This technology eventually “allowed for the alteration of specific amino acids in the sequence of the insulin protein to make insulin analogs [synthetic versions grown in E. coli and genetically altered for various properties] that act faster, or more slowly, than normal human insulin. By using the slow- and fast-acting insulins in combination, a patient can control their blood sugar levels with a much greater degree of finesse and precision,” Dr. Hall explained.
Today, a whole range of insulins are available, including ultra–rapid-acting, short-acting, intermediate-acting, long-acting, ultra–long-acting, and even inhaled insulin, although the latter is expensive, has been associated with side effects, and is less commonly used, according to Dr. Stephens.
Oral insulin formulations are even in the early stages of development, with candidate drugs by Generex and from the Oralis project.
“With insulin therapy, we try to reproduce the normal physiology of the healthy body and pancreas,” Dr. Stephens explained.
Insulin analogs are only made by three companies (Eli Lilly, Novo Nordisk, and Sanofi), and they are generally much more expensive than nonanalog human insulin. In the United Kingdom through the NHS, they cost twice as much.
In the United States today, one of the biggest barriers to proper care of type 1 diabetes is the cost of insulin, which can limit access. With the market controlled by these three large companies, the average cost of a unit of insulin in the United States, according to RAND research, was $98.17 in January 2021, compared with $7.52 in the United Kingdom and $12.00 in Canada.
Several U.S. states have enacted legislation capping insulin copayments to at, or under, $100 a month. But the federal Build Back Better Framework Act – which would cap copayments for insulin at $35 – currently hangs in the balance.
Alongside these moves, in 2020 the Food and Drug Administration approved the first interchangeable biosimilar insulin for type 1 diabetes (and insulin-dependent type 2 diabetes) in children and adults, called Semglee (Mylan Pharmaceuticals).
Biosimilars (essentially generic versions of branded insulins) are expected to be less expensive than branded analogs, but the indications so far are that they will only be around 20% cheaper.
“I totally fail to understand how the richest country in the world still has a debate about price caps, and we are looking at biosimilar markets to change the debate. This makes no sense to me at all,” stressed Dr. Kar. “For lifesaving drugs, they should be funded by the state.”
Insulin also remains unaffordable for many in numerous low- and middle-income countries, where most patients pay out-of-pocket for medicines. Globally, there are estimated to be around 30 million people who need insulin but cannot afford it.
How near to a cure in the coming decades?
Looking ahead to the coming years, if not the next 100, Dr. Stephens highlighted two important aspects of care.
First, the use of a CGM device in combination with an insulin pump (also known as a closed-loop system or artificial pancreas), where the CGM effectively tells the insulin pump how much insulin to automatically dispense, should revolutionize care.
A number of such closed-loop systems have recently been approved in both the United States, including systems from Medtronic and Omnipod, and Europe.
“I wear one of these and it’s been a life changer for me, but it doesn’t suit everyone because the technology can be cumbersome, but with time, hopefully things will become smaller and more accurate in insulin delivery,” Dr. Stephens added.
The second advance of interest is the development and transplantation of cells that produce insulin.
Dr. Stephens explained that someone living with type 1 diabetes has a lot to think about, not least, doing the math related to insulin requirement. “If we just had cells from a pancreas that could be transplanted and would do that for us, then it would be a total game changer.”
To date, Vertex Pharmaceuticals has successfully treated one patient – who had lived with type 1 diabetes for about 40 years and had recurrent episodes of severe hypoglycemia – with an infusion of stem cell–derived differentiated islet cells into his liver. The procedure resulted in near reversal of type 1 diabetes, with his insulin dose reduced from 34 to 3 units, and his hemoglobin A1c falling from 8.6% to 7.2%.
And although the patient, Brian Shelton, still needs to take immunosuppressive agents to prevent rejection of the stem cell–derived islets, “it’s a whole new life,” he recently told the New York Times.
Another company called ViaCyte is also working on a similar approach.
Whether this is a cure for type 1 diabetes is still debatable, said Anne Peters, MD, of the University of Southern California, Los Angeles. “Is it true? In a word, no. But we are part of the way there, which is much closer than we were 6 months ago.”
There are also ongoing clinical trials of therapeutic interventions to prevent or delay the trajectory from presymptomatic to clinical type 1 diabetes. The most advanced is the anti-CD3 monoclonal antibody teplizumab (Tzield, Provention Bio), which was rejected by the FDA in July 2021, but has since been refiled. The company expects to hear from the agency by the end of March 2022 as to whether the resubmission has been accepted.
Diabetes specialist nurses/educators keep it human
Dr. Hall said he concurs with the late eminent U.K. diabetes specialist Robert Tattersall’s observation on what he considers one of the most important advances in the management and treatment of type 1 diabetes: the human touch.
Referring to Dr. Tattersall’s book, “Diabetes: A Biography,” Dr. Hall quoted: “If asked what innovation had made the most difference to their lives in the 1980s, patients with type 1 diabetes in England would unhesitatingly have chosen not human insulin, but the spread of diabetes specialist nurses ... these people (mainly women) did more in the last two decades of the 20th century to improve the standard of diabetes care than any other innovation or drug.”
In the United States, diabetes specialist nurses were called diabetes educators until recently, when the name changed to certified diabetes care and education specialist.
“Above all, they have humanized the service and given the patient a say in the otherwise unequal relationship with all-powerful doctors,” concluded Dr. Hall, again quoting Dr. Tattersall.

Editor’s note: This is the second in a two-part series commemorating the 100-year anniversary of the first use of insulin in humans. Part 1 of this series examined the rivalry behind the discovery and use of insulin.
One hundred years ago, teenager Leonard Thompson was the first patient with type 1 diabetes to be successfully treated with insulin, granting him a reprieve from what was a certain death sentence at the time.
Since then, research has gathered pace. In the century since insulin’s discovery and first use, recombinant DNA technology has allowed for the engineering of the insulin molecule, providing numerous short- and long-acting analog versions. At the same time, technological leaps in automated insulin delivery and monitoring of blood glucose ensure more time with glucose in range and fewer life-threatening complications for those with type 1 diabetes fortunate enough to have access to the technology.
In spite of these advancements, there is still scope for further evolution of disease management, with the holy grail being the transplant of stem cell–derived islet cells capable of making insulin, ideally encased in some kind of protective device so that immunosuppression is not required.
Indeed, it is not unreasonable to “hope that type 1 diabetes will be a curable disease in the next 100 years,” said Elizabeth Stephens, MD, an endocrinologist who has type 1 diabetes and practices in Portland, Ore.
Type 1 diabetes: The past 100 years
The epidemiology of type 1 diabetes has shifted considerably since 1922. A century ago, given that average life expectancy in the United States was around 54 years, it was pretty much the only type of diabetes that doctors encountered. “There was some type 2 diabetes about in heavier people, but the focus was on type 1 diabetes,” noted Dr. Stephens.
Originally called juvenile diabetes because it was thought to only occur in children, “now 50% of people are diagnosed with type 1 diabetes ... over [the age of] 20,” explained Dr. Stephens.
In the United States, around 1.4 million adults 20 years and older, and 187,000 children younger than 20, have the disease, according to data from the National Diabetes Statistics Report 2020 by the Centers for Disease Control and Prevention. This total represents an increase of nearly 30% from 2017.
Over the years, theories as to the cause, or trigger, for type 1 diabetes “have included cow’s milk and [viral] infections,” said Dr. Stephens. “Most likely, there’s a genetic predisposition and some type of exposure, which creates the perfect storm to trigger disease.”
There are hints that COVID-19 might be precipitating type 1 diabetes in some people. Recently, the CDC found SARS-CoV-2 infection was associated with an increased risk for diabetes (all types) among youth, but not other acute respiratory infections. And two further studies from different parts of the world have recently identified an increase in the incidence of type 1 diabetes in children since the COVID-19 pandemic began, but the reasons remain unclear.
The global CoviDiab registry has also been established to collect data on patients with COVID-19–related diabetes.

The procedure resulted in near reversal of type 1 diabetes, with his insulin dose reduced from 34 to 3 units, and his hemoglobin A1c falling from 8.6% to 7.2%.
And although the patient, Brian Shelton, still needs to take immunosuppressive agents to prevent rejection of the stem cell–derived islets, “it’s a whole new life,” he recently told the New York Times.
Another company called ViaCyte is also working on a similar approach.
Whether this is a cure for type 1 diabetes is still debatable, said Anne Peters, MD, of the University of Southern California, Los Angeles. “Is it true? In a word, no. But we are part of the way there, which is much closer than we were 6 months ago.”
There are also ongoing clinical trials of therapeutic interventions to prevent or delay the trajectory from presymptomatic to clinical type 1 diabetes. The most advanced is the anti-CD3 monoclonal antibody teplizumab (Tzield, Provention Bio), which was rejected by the FDA in July 2021, but has since been refiled. The company expects to hear from the agency by the end of March 2022 as to whether the resubmission has been accepted.
Diabetes specialist nurses/educators keep it human
Dr. Hall said he concurs with the late eminent U.K. diabetes specialist Robert Tattersall’s observation on what he considers one of the most important advances in the management and treatment of type 1 diabetes: the human touch.
Referring to Dr. Tattersall’s book, “Diabetes: A Biography,” Dr. Hall quoted: “If asked what innovation had made the most difference to their lives in the 1980s, patients with type 1 diabetes in England would unhesitatingly have chosen not human insulin, but the spread of diabetes specialist nurses ... these people (mainly women) did more in the last two decades of the 20th century to improve the standard of diabetes care than any other innovation or drug.”
In the United States, diabetes specialist nurses were called diabetes educators until recently, when the name changed to certified diabetes care and education specialist.
“Above all, they have humanized the service and given the patient a say in the otherwise unequal relationship with all-powerful doctors,” concluded Dr. Hall, again quoting Dr. Tattersall.

Death of pig heart transplant patient is more a beginning than an end
The genetically altered pig’s heart “worked like a rock star, beautifully functioning,” the surgeon who performed the pioneering Jan. 7 xenotransplant procedure said in a press statement on the death of the patient, David Bennett Sr.
“He wasn’t able to overcome what turned out to be devastating – the debilitation from his previous period of heart failure, which was extreme,” said Bartley P. Griffith, MD, clinical director of the cardiac xenotransplantation program at the University of Maryland, Baltimore.
Representatives of the institution aren’t offering many details on the cause of Mr. Bennett’s death on March 8, 60 days after his operation, but said they will elaborate when their findings are formally published. But their comments seem to downplay the unique nature of the implanted heart itself as a culprit and instead implicate the patient’s diminished overall clinical condition and what grew into an ongoing battle with infections.
The 57-year-old Bennett, bedridden with end-stage heart failure, judged a poor candidate for a ventricular assist device, and on extracorporeal membrane oxygenation (ECMO), reportedly was offered the extraordinary surgery after being turned down for a conventional transplant at several major centers.
“Until day 45 or 50, he was doing very well,” Muhammad M. Mohiuddin, MD, the xenotransplantation program’s scientific director, observed in the statement. But infections soon took advantage of his hobbled immune system.
Given his “preexisting condition and how frail his body was,” Dr. Mohiuddin said, “we were having difficulty maintaining a balance between his immunosuppression and controlling his infection.” Mr. Bennett went into multiple organ failure and “I think that resulted in his passing away.”
Beyond wildest dreams
The surgeons confidently framed Mr. Bennett’s experience as a milestone for heart xenotransplantation. “The demonstration that it was possible, beyond the wildest dreams of most people in the field, even, at this point – that we were able to take a genetically engineered organ and watch it function flawlessly for 9 weeks – is pretty positive in terms of the potential of this therapy,” Dr. Griffith said.
But enough questions linger that others were more circumspect, even as they praised the accomplishment. “There’s no question that this is a historic event,” Mandeep R. Mehra, MD, of Harvard Medical School, and director of the Center for Advanced Heart Disease at Brigham and Women’s Hospital, both in Boston, said in an interview.
Still, “I don’t think we should just conclude that it was the patient’s frailty or death from infection,” Dr. Mehra said. With so few details available, “I would be very careful in prematurely concluding that the problem did not reside with the heart but with the patient. We cannot be sure.”
For example, he noted, “6 to 8 weeks is right around the time when some cardiac complications, like accelerated forms of vasculopathy, could become evident.” Immune-mediated cardiac allograft vasculopathy is a common cause of heart transplant failure.
Or, “it could as easily have been the fact that immunosuppression was modified at 6 to 7 weeks in response to potential infection, which could have led to a cardiac compromise,” Dr. Mehra said. “We just don’t know.”
“It’s really important that this be reported in a scientifically accurate way, because we will all learn from this,” Lori J. West, MD, DPhil, said in an interview.
Little seems to be known for sure about the actual cause of death, “but the fact there was not hyperacute rejection is itself a big step forward. And we know, at least from the limited information we have, that it did not occur,” observed Dr. West, who directs the Alberta Transplant Institute, Edmonton, and the Canadian Donation and Transplantation Research Program. She is a professor of pediatrics with adjunct positions in the departments of surgery and microbiology/immunology.
Dr. West also sees Mr. Bennett’s struggle with infections and adjustments to his unique immunosuppressive regimen, at least as characterized by his care team, as in line with the experience of many heart transplant recipients facing the same threat.
“We already walk this tightrope with every transplant patient,” she said. Typically, they’re put on a somewhat standardized immunosuppressant regimen, “and then we modify it a bit, either increasing or decreasing it, depending on the posttransplant course.” The regimen can become especially intense in response to new signs of rejection, “and you know that that’s going to have an impact on susceptibility to all kinds of infections.”
Full circle
The porcine heart was protected along two fronts against assault from Mr. Bennett’s immune system and other inhospitable aspects of his physiology, either of which could also have been obstacles to success: Genetic modification (Revivicor) of the pig that provided the heart, and a singularly aggressive antirejection drug regimen for the patient.
The knockout of three genes targeting specific porcine cell-surface carbohydrates that provoke a strong human antibody response reportedly averted a hyperacute rejection response that would have caused the graft to fail almost immediately.
Other genetic manipulations, some using CRISPR technology, silenced genes encoded for porcine endogenous retroviruses. Others were aimed at controlling myocardial growth and stemming graft microangiopathy.
Mr. Bennett himself was treated with powerful immunosuppressants, including an investigational anti-CD40 monoclonal antibody (KPL-404, Kiniksa Pharmaceuticals) that, according to UMSOM, inhibits a well-recognized pathway critical to B-cell proliferation, T-cell activation, and antibody production.
“I suspect the patient may not have had rejection, but unfortunately, that intense immunosuppression really set him up – even if he had been half that age – for a very difficult time,” David A. Baran, MD, a cardiologist from Sentara Advanced Heart Failure Center, Norfolk, Va., who studies transplant immunology, said in an interview.
“This is in some ways like the original heart transplant in 1967, when the ability to do the surgery evolved before understanding of the immunosuppression needed. Four or 5 years later, heart transplantation almost died out, before the development of better immunosuppressants like cyclosporine and later tacrolimus,” Dr. Baran said.
“The current age, when we use less immunosuppression than ever, is based on 30 years of progressive success,” he noted. This landmark xenotransplantation “basically turns back the clock to a time when the intensity of immunosuppression by definition had to be extremely high, because we really didn’t know what to expect.”
Emerging role of xeno-organs
Xenotransplantation has been touted as potential strategy for expanding the pool of organs available for transplantation. Mr. Bennett’s “breakthrough surgery” takes the world “one step closer to solving the organ shortage crisis,” his surgeon, Dr. Griffith, announced soon after the procedure. “There are simply not enough donor human hearts available to meet the long list of potential recipients.”
But it’s not the only proposed approach. Measures could be taken, for example, to make more efficient use of the human organs that become available, partly by opening the field to additional less-than-ideal hearts and loosening regulatory mandates for projected graft survival.
“Every year, more than two-thirds of donor organs in the United States are discarded. So it’s not actually that we don’t have enough organs, it’s that we don’t have enough organs that people are willing to take,” Dr. Baran said. Still, it’s important to pursue all promising avenues, and “the genetic manipulation pathway is remarkable.”
But “honestly, organs such as kidneys probably make the most sense” for early study of xenotransplantation from pigs, he said. “The waiting list for kidneys is also very long, but if the kidney graft were to fail, the patient wouldn’t die. It would allow us to work out the immunosuppression without putting patients’ lives at risk.”
Often overlooked in assessments of organ demand, Dr. West said, is that “a lot of patients who could benefit from a transplant will never even be listed for a transplant.” It’s not clear why; perhaps they have multiple comorbidities, live too far from a transplant center, “or they’re too big or too small. Even if there were unlimited organs, you could never meet the needs of people who could benefit from transplantation.”
So even if more available donor organs were used, she said, there would still be a gap that xenotransplantation could help fill. “I’m very much in favor of research that allows us to continue to try to find a pathway to xenotransplantation. I think it’s critically important.”
Unquestionably, “we now need to have a dialogue to entertain how a technology like this, using modern medicine with gene editing, is really going to be utilized,” Dr. Mehra said. The Bennett case “does open up the field, but it also raises caution.” There should be broad participation to move the field forward, “coordinated through either societies or nationally allocated advisory committees that oversee the movement of this technology, to the next step.”
Ideally, that next step “would be to do a safety clinical trial in the right patient,” he said. “And the right patient, by definition, would be one who does not have a life-prolonging option, either mechanical circulatory support or allograft transplantation. That would be the goal.”
Dr. Mehra has reported receiving payments to his institution from Abbott for consulting; consulting fees from Janssen, Mesoblast, Broadview Ventures, Natera, Paragonix, Moderna, and the Baim Institute for Clinical Research; and serving on a scientific advisory board NuPulseCV, Leviticus, and FineHeart. Dr. Baran disclosed consulting for Getinge and LivaNova; speaking for Pfizer; and serving on trial steering committees for CareDx and Procyrion, all unrelated to xenotransplantation. Dr. West has declared no relevant conflicts.
