Aerococcus urinae (A urinae), a gram-positive coccus readily mistaken for a Staphylococcus species, was first identified in 1992.^1-3 It now reportedly accounts for 0.2% to 0.8% of clinical urine isolates.^4-6 A urinae bacteriuria is typically asymptomatic and mainly occurs in women.^7-9 Symptomatic A urinae urinary tract infection (UTI) occurs predominantly in older men with underlying urologic abnormalities.^4-10 

Serious A urinae infections are rare. The first 2 reported cases involved men with A urinae endocarditis, one of whom died.^11,12 To date, only 8 cases of spondylodiscitis due to A urinae have been reported.^13-20 Optimal treatment for invasive A urinae infection is undefined; however, the reported cases were treated successfully with diverse antibiotic regimen combinations; all including a β-lactam and beginning with at least 2 weeks of IV antibiotics.^13-20 We describe a man with A urinae bacteremia and spondylodiscitis, presumably arising from a urinary source in the setting of bladder outlet obstruction, who was treated successfully.

Case Presentation

A 74-year-old man with morbid obesity, type 2 diabetes mellitus, stage 2 chronic kidney disease, and tobacco use presented to the emergency department after 2 weeks of progressive, nonradiating, midthoracic back pain, lower extremity weakness, gait imbalance, fatigue, anorexia, rigors, and subjective fevers. On presentation, he was afebrile and hemodynamically stable. A physical examination revealed point tenderness of the midthoracic vertebrae, nontender costovertebral angles, diffusely decreased strength, nonsustained clonus in both lower extremities, inguinal intertrigo, and a buried penis with purulent meatal discharge.

Laboratory results indicated a white blood cell (WBC) count of 13.5 K/μL (reference range, 4.0-11.0), absolute neutrophil count of 11.48 K/μL (reference range, 2.0-7.7), C-reactive protein (CRP) level of 225.3 mg/L (reference range, ≤ 5.0), erythrocyte sedimentation rate of 85 mm/h (reference range, 5-15), serum blood urea nitrogen of 76 mg/dL (reference range, 8-26), and serum creatinine (SCr) of 1.9 mg/dL (reference range, 1.1-1.4). A urinalysis showed positive leukocyte esterase, WBC clumps, and little bacteria. Abdominal/pelvic computed tomography showed spondylodiscitis-like changes at T7-T8, bilateral perinephric fat stranding, bladder distension, and bladder wall thickening.

The patient was presumed to have discitis secondary to a UTI, with possible pyelonephritis, and was given empiric vancomycin and ceftriaxone. Spinal magnetic resonance imaging with contrast supported spondylodiscitis at T7-T8, extending to T8-T9. Preliminary results from the admission blood and urine cultures showed gram-positive cocci in clusters, which were presumed initially to be Staphylococcus aureus (S aureus).

The final urine culture report listed multiple organisms, predominantly A urinae (Table 1);

On hospital day 6, the patient’s back pain had resolved, micturition was normal, appetite had normalized, and SCr was minimally above baseline (1.4 mg/dL). He insisted on completing antibiotic treatment at home and had no other medical indication for continued hospitalization. Thus, antibiotic therapy was changed to an all-oral regimen of amoxicillin 1 g 3 times daily for 10 days and levofloxacin 750 mg daily for 6 weeks, and the patient was discharged to home.

The patient returned 5 days postdischarge due to anuria. Investigation showed severe acute kidney injury (SCr, 6.8 mg/dL) and bladder outlet obstruction due to phimosis and urethral meatal stenosis. Urinalysis was unremarkable. His CRP had declined from 225 mg/L (initial admission) to 154 mg/L. A urinae culture and 2 sets of blood cultures were finalized as no growth. He was diagnosed with postrenal acute kidney injury and underwent meatal dilation and Foley catheterization but declined surgical correction. When seen in the clinic 2 months postantimicrobial therapy, the patient had normal micturition, no symptoms or signs of infection, and steadily down-trending inflammatory markers.

Discussion

A urinae, historically considered a rare pathogen, has been identified with increasing frequency in urine cultures due to improved microbiologic diagnostic techniques. However, there are only 8 reported cases of A urinae spondylodiscitis. Urinary pathology is an accepted risk factor for A urinae infections; consequently, we suspect that our patient’s urinary outflow obstruction and poor genitourinary hygiene were related to his invasive A urinae infection.^10,21,22 We surmise that he had a chronic urinary outflow obstruction contributing to his infection, as evidenced by imaging findings, while the phimosis and urethral meatal stenosis were most likely infectious sequelae considering his anuria and acute kidney injury 5 days postdischarge. Indeed, the correlation between A urinae and urinary tract pathology may justify an evaluation for urinary pathology in any man with A urinae infection, regardless of the presence of symptoms.

By contrast, the implications of A urinae bacteriuria remain unclear. From a public health perspective, A urinae bacteriuria is rare, but the infectious mechanism remains undetermined with a case report suggesting the possibility of sexual transmission.^4-6,23 In our case, the patient was not sexually active and had no clear origin of infection. Considering the potential severity of infection, more studies are needed to determine the infectious mechanism of A urinae.

In terms of infectious morbidity, the results seem to vary by sex. In a retrospective study of about 30,000 clinical urine samples, 62 (58 from women, 4 from men) yielded A urinae. The 62 corresponding patients lacked systemic infectious complications, leading the authors to conclude that A urinae is a relatively avirulent organism.²⁴ Although possibly true in women, we are wary of drawing conclusions, especially regarding men, from a study that included only 62 urine samples were A urinae–positive, with only 4 from men. More evidence is needed to define the prognostic implications of A urinae bacteriuria in men.

As illustrated by the present case and previous reports, severe A urinae infections can occur, and the contributory factors deserve consideration. In our patient, the actual mechanism for bacteremia remains unclear. The initial concern for acute pyelonephritis was prompted by a computed tomography finding of bilateral perinephric fat stranding. This finding was questioned because it is common in older patients without infection, hence, is highly nonspecific. A correlation with urinary outflow obstruction may be an important clue in cases like this one.^25,26

Furthermore, whether the urinary tract truly was the source of the patient’s bacteremia is clouded by the differing antimicrobial susceptibility patterns of the A urinae blood and urine isolates. The simplest explanation for this discordance may be that all the isolates shared a common initial origin but adapted to different environments in the host (perhaps over time) or laboratory, producing phenotypic variation. Alternatively, the infection could have been polyclonal from the onset, with sampling error leading to the differing detected susceptibility patterns, or the blood and urine isolates may have represented independent acquisition events, involving distinct A urinae strains. Unfortunately (from an academic perspective), given patient preferences and recommendations from the infectious disease consultant, no bone biopsy was done for histology and culture to confirm infection and to allow comparative strain identification if A urinae was isolated. 

Optimal treatment for A urinae spondylodiscitis has yet to be established. β-lactams have shown good clinical efficacy despite being bacteriostatic in vitro.²⁷ Early in vitro studies showed synergistic bactericidal synergistic activity with penicillin plus aminoglycoside combination therapies.^27-30 Cases of endocarditis have been successfully treated mainly with the combination of a β-lactam plus aminoglycoside combination therapy.^30,31 Previous cases of spondylodiscitis have been treated successfully with diverse antimicrobial agents, including clindamycin, β-lactams, cephalosporins, fluoroquinolones, and aminoglycosides.¹⁴

Our patient improved rapidly while receiving empiric therapy with vancomycin and ceftriaxone and tolerated a rapid transition to oral amoxicillin and levofloxacin. This is the shortest IV treatment course for A urinae spondylodiscitis reported to date. We suspect that such rapid IV-to-oral transitions will suffice in most stable patients with A urinae spondylodiscitis or other invasive A urinae infections in line with the results of the OVIVA and POET trials.^32,33

Conclusions

We believe A urinae UTI in the absence of obvious predisposing factors should prompt evaluation for urinary outflow obstruction. Despite improved laboratory diagnostic techniques, spondylodiscitis related to A urinae remains a rare entity and thus definitive treatment recommendations are difficult to make. However, we suspect that in many cases it is reasonable to extrapolate from the results of the POET and OVIVA trials and rapidly transition therapy of A urinae spondylodiscitis from IV to oral antibiotics. We suspect a review of the US Department of Veterans Affairs population might uncover a higher incidence of A urinae infection than previously estimated due to the population demographics and the epidemiology of A urinae.

The financial burden of contemporary care for hepatocellular carcinoma (HCC) is high for Medicare beneficiaries, a new analysis shows.

In the first year after a diagnosis of HCC, median Medicare payments exceed $65,000 and out-of-pocket costs top $10,000.

Even after adjustment for the presence of cirrhosis and its related costs, patients with HCC still have Medicare payments exceeding $50,000 and out-of-pocket costs topping $7000.

Amit Singal, MD, of UT Southwestern Medical Center in Dallas, and colleagues reported their findings in Clinical Gastroenterology and Hepatology.
 

Common and costly

HCC, the most common type of primary liver cancer, is a leading cause of death in patients with cirrhosis and is projected to become the third leading cause of cancer-related death in the United States by 2040, the researchers wrote.

The treatment landscape for HCC has changed over the past decade, with expanded surgical options, introduction of radiation-based therapies, and approval of immunotherapies – all of which are costly.

Yet the magnitude of financial burden of HCC therapy has been understudied, the researchers noted.

To investigate, Dr. Singal and colleagues evaluated Surveillance, Epidemiology, and End Results (SEER)–Medicare data for 4,525 adults with traditional Medicare coverage who were diagnosed with HCC between 2011 and 2015 and a propensity-matched cohort of 4,525 adults with cirrhosis but no HCC as a comparator group to tease out HCC-specific costs beyond those related to cirrhosis. Patients in Medicare managed care were excluded because their cost information is not available in the database.

In the first year after a diagnosis of HCC, the median total Medicare payments were $66,338 (interquartile range [IQR], $30,931-$158,740) and patient liabilities (a proxy for out-of-pocket costs) were $10,008 (IQR, $5,427-$19,669).

First-year costs were higher for patients with HCC than matched patients without HCC; the former group incurred median incremental Medicare payments of $50,110 (IQR, $14,242-$136,239) and patient liabilities of $7,166 (IQR, $2,401-$16,099), the investigators found.

Patients with early-stage HCC had lower incremental patient liabilities (median, $4,195 vs. $8,238) and Medicare payments (median, $28,207 vs. $59,509) than did their peers with larger tumor burden.
 

NAFLD notably tied to higher costs

Factors associated with higher HCC-related costs were nonalcoholic fatty liver disease (NAFLD) etiology, higher comorbidities, presence of ascites and hepatic encephalopathy, and larger tumor burden.

The researchers said that the link between NAFLD and higher costs is notable, given that NAFLD is an increasingly common underlying cause of HCC.

The link between larger tumor burden and higher costs underscores “another benefit of HCC surveillance and early detection,” they added.

“By separating the financial liabilities borne by patients and Medicare, we provide a clearer outlook of how cancer-related costs are distributed between patients and public payers,” Dr. Singal and colleagues said.

“Our findings will inform policy interventions and will help formulate better financial supports targeting the most vulnerable HCC patients,” they concluded.

The study had no commercial funding. Dr. Singal has been on advisory boards and served as a consultant for Wako Diagnostics, Glycotest, Exact Sciences, Roche, Genentech, Bayer, Eisai, BMS, Exelixis, AstraZeneca, and TARGET RWE.

The financial burden of contemporary care for hepatocellular carcinoma (HCC) is high for Medicare beneficiaries, a new analysis shows.

In the first year after a diagnosis of HCC, median Medicare payments exceed $65,000 and out-of-pocket costs top $10,000.

Even after adjustment for the presence of cirrhosis and its related costs, patients with HCC still have Medicare payments exceeding $50,000 and out-of-pocket costs topping $7000.

Amit Singal, MD, of UT Southwestern Medical Center in Dallas, and colleagues reported their findings in Clinical Gastroenterology and Hepatology.
 

Common and costly

HCC, the most common type of primary liver cancer, is a leading cause of death in patients with cirrhosis and is projected to become the third leading cause of cancer-related death in the United States by 2040, the researchers wrote.

The treatment landscape for HCC has changed over the past decade, with expanded surgical options, introduction of radiation-based therapies, and approval of immunotherapies – all of which are costly.

Yet the magnitude of financial burden of HCC therapy has been understudied, the researchers noted.

To investigate, Dr. Singal and colleagues evaluated Surveillance, Epidemiology, and End Results (SEER)–Medicare data for 4,525 adults with traditional Medicare coverage who were diagnosed with HCC between 2011 and 2015 and a propensity-matched cohort of 4,525 adults with cirrhosis but no HCC as a comparator group to tease out HCC-specific costs beyond those related to cirrhosis. Patients in Medicare managed care were excluded because their cost information is not available in the database.

In the first year after a diagnosis of HCC, the median total Medicare payments were $66,338 (interquartile range [IQR], $30,931-$158,740) and patient liabilities (a proxy for out-of-pocket costs) were $10,008 (IQR, $5,427-$19,669).

First-year costs were higher for patients with HCC than matched patients without HCC; the former group incurred median incremental Medicare payments of $50,110 (IQR, $14,242-$136,239) and patient liabilities of $7,166 (IQR, $2,401-$16,099), the investigators found.

Patients with early-stage HCC had lower incremental patient liabilities (median, $4,195 vs. $8,238) and Medicare payments (median, $28,207 vs. $59,509) than did their peers with larger tumor burden.
 

NAFLD notably tied to higher costs

Factors associated with higher HCC-related costs were nonalcoholic fatty liver disease (NAFLD) etiology, higher comorbidities, presence of ascites and hepatic encephalopathy, and larger tumor burden.

The researchers said that the link between NAFLD and higher costs is notable, given that NAFLD is an increasingly common underlying cause of HCC.

The link between larger tumor burden and higher costs underscores “another benefit of HCC surveillance and early detection,” they added.

“By separating the financial liabilities borne by patients and Medicare, we provide a clearer outlook of how cancer-related costs are distributed between patients and public payers,” Dr. Singal and colleagues said.

“Our findings will inform policy interventions and will help formulate better financial supports targeting the most vulnerable HCC patients,” they concluded.

The study had no commercial funding. Dr. Singal has been on advisory boards and served as a consultant for Wako Diagnostics, Glycotest, Exact Sciences, Roche, Genentech, Bayer, Eisai, BMS, Exelixis, AstraZeneca, and TARGET RWE.

A former associate professor at Purdue University faked data in two published papers and hundreds of images in 16 grant applications, according to a U.S. government research watchdog. 

Alice C. Chang, PhD, whose publications and grants listed her name as Chun-Ju Chang, received nearly $700,000 in funding from the National Institutes of Health through grant applications that the U.S. Office of Research Integrity said contained fake data. She will be banned from receiving federal grants for a decade – a more severe sanction than ORI has typically imposed in recent years.

In its findings, ORI said Dr. Chang, who was an associate professor of basic medical sciences at Purdue’s College of Veterinary Medicine, West Lafayette, Ind., “knowingly, intentionally, or recklessly falsified and/or fabricated data from the same mouse models or cell lines by reusing the data, with or without manipulation, to represent unrelated experiments from different mouse models or cell lines with different treatments in three hundred eighty-four (384) figure panels in sixteen (16) grant applications.”

Two of the grant applications were funded. Dr. Chang received $688,196 from the National Cancer Institute, a division of NIH, from 2018 to 2019 for “Targeting metformin-directed stem cell fate in triple negative breast cancer.” The other grant ORI says was submitted in 2014 and funded, “Targeting cell polarity machinery to exhaust breast cancer stem cell pool,” does not show up in NIH RePorter. The rest of the grants were not approved. 

We found a Chun-Ju Chang who is dean of the College of Life Sciences at China Medical University in Taiwan and has published papers with a group that Chun-Ju Chang at Purdue also published with. She did not immediately respond to our request for comment. 

ORI’s finding also stated Dr. Chang faked data in two papers supported by government funding by reusing figures reporting gene expression in mice and cells after drug treatments, relabeling them to say they showed the results of different experiments. According to the agency, she has agreed to request corrections for the papers: 

“Leptin–STAT3–G9a Signaling Promotes Obesity-Mediated Breast Cancer Progression,” published in May 2015 in Cancer Research and cited 83 times, according to Clarivate’s Web of Science. 

“Retinoic acid directs breast cancer cell state changes through regulation of TET2-PKC-zeta pathway,” published in February 2017 in Oncogene and cited 26 times. 

Between the two papers and 15 of the grant applications, ORI said that Dr. Chang reused gene expression data, sometimes with manipulation, in 119 figure panels. She reused other types of data and images in hundreds of figures across multiple grant applications, ORI found. 

As well as correcting the two papers, Dr. Chang agreed to a 10-year ban from all federal contracting, including grant funding. She also agreed not to serve in any advisory or consulting role with the U.S. Public Health Service, which includes the NIH, for that time period.

In a small randomized controlled trial of patients with type 2 diabetes in China, close to half of those who followed a novel intermittent fasting program for 3 months had diabetes remission (A1c less than 6.5% without taking antidiabetic drugs) that persisted for 1 year.

Importantly, “this study was performed under real-life conditions, and the intervention was delivered by trained nurses in primary care rather than by specialized staff at a research institute, making it a more practical and achievable way to manage” type 2 diabetes, the authors report.

Moreover, 65% of the patients in the intervention group who achieved diabetes remission had had diabetes for more than 6 years, which “suggests the possibility of remission for patients with longer duration” of diabetes, they note.

‘Excellent outcome’

Invited to comment, Amy E. Rothberg, MD, PhD, who was not involved with the research, agreed that the study indicates that intermittent fasting works for diabetes remission.

“We know that diabetes remission is possible with calorie restriction and subsequent weight loss, and intermittent fasting is just one of the many [dietary] approaches that may be suitable, appealing, and sustainable to some individuals, and usually results in calorie restriction and therefore weight loss,” she said.

The most studied types of intermittent fasting diets are alternate-day fasting, the 5:2 diet, and time-restricted consumption, Dr. Rothberg told this news organization.

This study presented a novel type of intermittent fasting, she noted. The intervention consisted of 6 cycles (3 months) of 5 fasting days followed by 10 ad libitum days, and then 3 months of follow-up (with no fasting days).

After 3 months of the intervention plus 3 months of follow-up, 47% of the 36 patients in the intervention group achieved diabetes remission (with a mean A1c of 5.66%), compared with only 2.8% of the 36 patients in the control group.

At 12 months, 44% of patients in the intervention group had sustained diabetes remission (with a mean A1c of 6.33%).

This was “an excellent outcome,” said Dr. Rothberg, professor of nutritional sciences, School of Public Health, University of Michigan, Ann Arbor, and a co-author of an international consensus statement that defined diabetes remission.

On average, patients in the intermittent fasting group lost 5.93 kg (13.0 lb) in 3 months, which was sustained over 12 months. “The large amount of weight reduction is key to continuing to achieve diabetes remission,” she noted.

This contrasted with an average weight loss of just 0.27 kg (0.6 lb) in the control group.

Participants who were prescribed fewer antidiabetic medications were more likely to achieve diabetes remission. The researchers acknowledge that the study was not blinded, and they did not record physical activity (although participants were encouraged to maintain their usual physical activity).

This was a small study, Dr. Rothberg acknowledged. The researchers did not specify which specific antidiabetic drugs patients were taking, and they did not determine waist or hip circumference or assess lipids.

The diet was culturally sensitive, appropriate, and feasible in this Chinese population and would not be generalizable to non-Asians.

Nevertheless, a similar approach could be used in any population if the diet is tailored to the individual, according to Dr. Rothberg. Importantly, patients would need to receive guidance from a dietician to make sure their diet comprises all the necessary micronutrients, vitamins, and minerals on fasting days, and they would need to maintain a relatively balanced diet and not gorge themselves on feast days. 

“I think we should campaign widely about lifestyle approaches to achieve diabetes remission,” she urged.
 

72 patients with diabetes for an average of 6.6 years

“Despite a widespread public consensus that [type 2 diabetes] is irreversible and requires drug treatment escalation, there is some evidence of the possibility of remission,” Dr. Yang and colleagues write in their article.

They aimed to evaluate the effectiveness of intermittent fasting for diabetes remission and the durability of diabetes remission at 1 year.

Diabetes remission was defined having a stable A1c less than 6.5% for at least 3 months after discontinuing all antidiabetic medications, confirmed in at least annual A1c measurements (according to a 2021 consensus statement initiated by the American Diabetes Association).

Between 2019 and 2020, the researchers enrolled 72 participants aged 38-72 years who had had type 2 diabetes (duration 1 to 11 years) and a body mass index (BMI) of 19.1-30.4 kg/m². Patients were randomized 1:1 to the intermittent fasting group or control group.

Baseline characteristics were similar in both groups. Patients were a mean age of 53 years and roughly 60% were men. They had a mean BMI of 24 kg/m², a mean duration of diabetes of 6.6 years, and a mean A1c of 7.6%, and they were taking an average of 1.8 glucose-lowering medications.  

On fasting days, patients in the intervention group received a Chinese Medical Nutrition Therapy kit that provided approximately 840 kcal/day (46% carbohydrates, 46% fat, 8% protein). The kit included a breakfast of a fruit and vegetable gruel, lunch of a solid beverage plus a nutritional rice composite, and dinner of a solid beverage and a meal replacement biscuit, which participants reconstituted by mixing with boiling water. They were allowed to consume noncaloric beverages.

On nonfasting days, patients chose foods ad libitum based on the 2017 Dietary Guidelines for Diabetes in China, which recommend approximately 50%-65% of total energy intake from carbohydrates, 15%-20% from protein, and 20%-30% from fat, and had greater than or equal to 5 g fiber per serving.

Patients in the control group chose foods ad libitum from the dietary guidelines during the entire study.

The study received funding from the National Natural Science Foundation of China. The authors have reported no relevant financial disclosures.

Scientists are one step closer to developing a breakthrough technology that could lead to a vaccine for HIV, which infects more than 1 million people worldwide each year.

The announcement comes from the journal Science, which published phase 1 results of a small clinical trial for a vaccine technology that aims to cause the body to create a rare kind of cell.

“At the most general level, the trial results show that one can design vaccines that induce antibodies with prespecified genetic features, and this may herald a new era of precision vaccines,” William Schief, PhD, a researcher at the Scripps Research Institute and study coauthor, told the American Association for the Advancement of Science.

The study was the first to test the approach in humans and was effective in 97% – or 35 of 36 – participants. The vaccine technology is called “germline targeting.” Trial results show that “one can design a vaccine that elicits made-to-order antibodies in humans,” Dr. Schief said in a news release.

In addition to possibly being a breakthrough for the treatment of HIV, the vaccine technology could also impact the development of treatments for flu, hepatitis C, and coronaviruses, study authors wrote.

There is no cure for HIV, but there are treatments to manage how the disease progresses. HIV attacks the body’s immune system, destroys white blood cells, and increases susceptibility to other infections, AAAS summarized. More than 1 million people in the United States and 38 million people worldwide have HIV.

Previous HIV vaccine attempts were not able to cause the production of specialized cells known as “broadly neutralizing antibodies,” CNN reported.

“Call them super antibodies, if you want,” University of Minnesota HIV researcher Timothy Schacker, MD, who was not involved in the research, told CNN. “The hope is that if you can induce this kind of immunity in people, you can protect them from some of these viruses that we’ve had a very hard time designing vaccines for that are effective. So this is an important step forward.”

Study authors said this is just the first step in the multiphase vaccine design, which so far is a theory. Further study is needed to see if the next steps also work in humans, and then if all the steps can be linked together and can be effective against HIV.

Study authors said this is just the first step in the multiphase vaccine design, which so far is a theory. Further study is needed to see if the next steps also work in humans, and then if all the steps can be linked together and can be effective against HIV.

Scientists are one step closer to developing a breakthrough technology that could lead to a vaccine for HIV, which infects more than 1 million people worldwide each year.

The announcement comes from the journal Science, which published phase 1 results of a small clinical trial for a vaccine technology that aims to cause the body to create a rare kind of cell.

“At the most general level, the trial results show that one can design vaccines that induce antibodies with prespecified genetic features, and this may herald a new era of precision vaccines,” William Schief, PhD, a researcher at the Scripps Research Institute and study coauthor, told the American Association for the Advancement of Science.

The study was the first to test the approach in humans and was effective in 97% – or 35 of 36 – participants. The vaccine technology is called “germline targeting.” Trial results show that “one can design a vaccine that elicits made-to-order antibodies in humans,” Dr. Schief said in a news release.

In addition to possibly being a breakthrough for the treatment of HIV, the vaccine technology could also impact the development of treatments for flu, hepatitis C, and coronaviruses, study authors wrote.

There is no cure for HIV, but there are treatments to manage how the disease progresses. HIV attacks the body’s immune system, destroys white blood cells, and increases susceptibility to other infections, AAAS summarized. More than 1 million people in the United States and 38 million people worldwide have HIV.

Previous HIV vaccine attempts were not able to cause the production of specialized cells known as “broadly neutralizing antibodies,” CNN reported.

“Call them super antibodies, if you want,” University of Minnesota HIV researcher Timothy Schacker, MD, who was not involved in the research, told CNN. “The hope is that if you can induce this kind of immunity in people, you can protect them from some of these viruses that we’ve had a very hard time designing vaccines for that are effective. So this is an important step forward.”

There are many holy grails in medicine, with failure after failure, like finding a way to prevent Alzheimer’s disease or a noninvasive means for accurately measuring ambulatory blood pressure. But one of the biggest and most daunting has been finding drugs that can tackle obesity – achieving a substantial amount of weight loss without serious side effects. Many attempts to get there now fill a graveyard of failed drugs, such as fen-phen in the 1990s when a single small study of this drug combination in 121 people unleashed millions of prescriptions, some leading to serious heart valve lesions that resulted in withdrawal of the drug in 1995. The drug rimonabant, an endocannabinoid receptor blocker (think of blocking the munchies after marijuana) looked encouraging in randomized trials. However, subsequently, in a trial that I led of nearly 19,000 participants in 42 countries around the world, there was a significant excess of depression, neuropsychiatric side-effects and suicidal ideation which spelled the end of that drug’s life.

In the United States, where there had not been an antiobesity drug approved by the Food and Drug Administration since 2014, Wegovy (semaglutide), a once-weekly injection was approved in June 2021. The same drug, at a lower dose, is known as Ozempic (as in O-O-O, Ozempic, the ubiquitous commercial that you undoubtedly hear and see on TV) and had already been approved in January 2020 for improving glucose regulation in diabetes. The next drug on fast track at FDA to be imminently approved is tirzepatide (Mounjaro) following its approval for diabetes in May 2022. It is noteworthy that the discovery of these drugs for weight loss was serendipitous: they were being developed for improving glucose regulation and unexpectedly were found to achieve significant weight reduction.

Both semaglutide and tirzepatide underwent randomized, placebo-controlled trials for obesity, with marked reduction of weight as shown below. Tirzepatide at dose of 10-15 mg per week achieved greater than 20% body weight reduction. Semaglutide at a dose of 2.4 mg achieved about 17% reduction. These per cent changes in body weight are 7-9 fold more than seen with placebo (2%-3% reduction). Note: these levels of percent body-weight reduction resemble what is typically achieved with the different types of bariatric surgery, such as gastric bypass.

How do these drugs work?

These are peptides in the class of incretins, mimicking gut hormones that are secreted after food intake which stimulate insulin secretion.

How they are given and practical considerations

For semaglutide, which has FDA approval, the indication is a body mass index of 30 kg/m² or greater than 27 and a weight-related medical condition (such as hypertension, hypercholesterolemia, or diabetes). To reduce the GI side effects, which mainly occur in the early dose escalation period, semaglutide is given in increasing doses by a prefilled pen by self-injection under the skin (abdomen, thigh, or arm) starting at 0.25 mg for a month and gradual increases each month reaching the maximum dose of 2.4 mg at month 5. The FDA label for dosing of tirzepatide has not been provided yet but in the weight loss trial there was a similar dose escalation from 2.5 mg up to 15 mg by month 5. The escalation is essential to reduce the frequent GI side effects, such as seen below in the tirzepatide trial.

What does this mean?

More than 650 million adults and 340 million children aged 5-18 are obese. The global obesity epidemic has been relentless, worsening each year, and a driver of “diabesity,” the combined dual epidemic. We now have a breakthrough class of drugs that can achieve profound weight loss equivalent to bariatric surgery, along with the side benefits of reducing cardiovascular risk factors (hypertension and hyperlipidemia), improving glucose regulation, reversing fatty liver, and the many detrimental long-term effects of obesity such as osteoarthritis and various cancers. That, in itself, is remarkable. Revolutionary.

But the downsides are also obvious. Self-injections, even though they are once a week, are not palatable for many. We have seen far more of these injectables in recent years such as the proprotein convertase subtilisin/kexin type 9 inhibitors for hypercholesterolemia or the tumor necrosis factor blockers for autoimmune conditions. That still will not make them a popular item for such an enormous population of potential users.

That brings me to Rybelsus, the oral form of semaglutide, which is approved for glucose regulation improvement but not obesity. It effects for weight loss have been modest, compared with Wegovy (5 to 8 pounds for the 7- and 14-mg dose, respectively). But the potential for the very high efficacy of an injectable to be achievable via a pill represents an important path going forward—it could help markedly reduce the cost and uptake.

The problem of discontinuation of the drugs is big, since there are limited data and the likelihood is that the weight will be regained unless there are substantial changes in lifestyle. We know how hard it is to durably achieve such changes, along with the undesirability (and uncertainty with respect to unknown side effects) of having to take injectable drugs for many years, no less the cost of doing that.

The cost of these drugs will clearly and profoundly exacerbate inequities, since they are eminently affordable by the rich, but the need is extreme among the indigent. We’ve already seen celebrities take Wegovy for weight loss who are not obese, a window into how these drugs can and will be used without supportive data. As one physician recently observed, “Other than Viagra and Botox, I’ve seen no other medication so quickly become part of modern culture’s social vernacular.” Already there are concerns that such use is preventing access to the drugs for those who qualify and need them.

There are multiple agents in the class under development which should help increase competition and reduce cost, but they will remain expensive. There is private insurance reimbursement, often with a significant copay, for people who tightly fit the inclusion criteria. Eventual coverage by Medicare will markedly expand their use, and we can expect cost-effectiveness studies to be published showing how much saving there is for the drugs compared with bariatric surgery or not achieving the weight loss. But that doesn’t change the cost at the societal level. Even as we’ve seen with generics, which will ultimately be available, the alleviation of the cost problem isn’t what we’d hoped.

This is not unlike the recent triumphs of gene therapy, as in $3.5 million for a cure of hemophilia that just got FDA approval, but instead of a rare disease we are talking about the most common medical condition in the world. We finally get across the long sought after (what many would qualify as miraculous) goal line, but the economics collide with the uptake and real benefit.

These concerns can’t be put aside in the health inequity-laden world we live in, that will unquestionably be exacerbated. However, we cannot miss that this represents one of the most important, biggest medical breakthroughs in history. This may signify the end or marked reduction in the need for bariatric surgery. These drugs will likely become some of the most prescribed of all medications in the upcoming years. While there are many drawbacks, we shouldn’t miss such an extraordinary advance in medicine – the first real, potent and safe treatment of obesity.

Drew Ramsey, MD: Welcome back, everyone. I’m Dr. Drew Ramsey. I’m on the editorial board with Medscape Psychiatry and I’m an assistant clinical professor of psychiatry at Columbia University. We have a special guest today.

I’m here with nutritionist Jessica Bayes, who’s at the University of Technology Sydney, and she’s the lead author of the AMMEND trial. [Editor’s note: Since completing her PhD, Bayes is now at Southern Cross University.] The AMMEND trial is our most recent trial in nutritional psychiatry, finding that giving or helping young men eat a Mediterranean diet can be helpful in the treatment of depression.

Jessica, welcome to Medscape.

Jessica Bayes, PhD: Thank you for having me.

The AMMEND Trial

Dr. Ramsey: Thank you for coming on board and helping all of us as clinicians understand some of your research and some of what is suggested by your research – that young men can change their diet and it helped their depression. Tell us a little bit about the AMMEND trial.

Dr. Bayes: The AMMEND trial was a 12-week randomized controlled trial in young men, 18-25 years old, who had diagnosed moderate to severe clinical depression. They had a poor baseline diet and we got them to eat a healthy Mediterranean diet, which improved their symptoms of depression.

Dr. Ramsey: It was a remarkable trial. Jessica, if I recall, you helped individuals improve the Mediterranean dietary pattern score by 8 points on a 14-point scale. That led to a 20-point reduction in their Beck Depression Inventory. Tell us what that looked like on the ground.

Dr. Bayes: It’s a huge improvement. Obviously, they were feeling much better in the end in terms of their depressive symptoms, but we also measured their energy, sleep, and quality of life. Many of them at the end were at a score cutoff that suggests no depression or in remission.

Dr. Ramsey: There were 72 people in your total trial, so 36% in your intervention arm went into full remission.

Dr. Bayes: Which is just amazing.

Dr. Ramsey: It also follows up the SMILES trial, which was a little bit of a different trial. You had two nutritional counseling sessions and the SMILES trial had seven, but in the SMILES trial, 32.3% of the patients went into full remission when they adopted a Mediterranean-style diet.

Jessica, what is the secret that you and your team know? I think many clinicians, especially clinicians who are parents and have teens, are kind of shaking their heads in disbelief. They’ve been telling their kids to eat healthy. What do you guys know about how to help young men change their diet?

How to Aid Adherence to Mediterranean Diet

Dr. Bayes: Prior to starting this, when I would say this idea to people, everyone would say, “Great idea. There’s no way you’re going to get depressed young men to change their diet. Not going to happen.” We went to them and we asked them. We said, “We’re going to do this study. What do you want from us? What resources would you need? How many appointments would you like? What’s too little or too many?”

We really got their feedback on board when we designed the study, and that obviously paid off. We had a personalized approach and we met them where they were at. We gave them the skills, resources, recipes, meal ideas – all those things – so we could really set them up to succeed.

Dr. Ramsey: You were telling me earlier about a few of the dietary changes that you felt made a big difference for these young men. What were those?

Dr. Bayes: Increasing the vegetables, olive oil, and legumes are probably the big ones that most of them were really not doing beforehand. They were really able to take that on board and make significant improvements in those areas.

Dr. Ramsey: These are really some of the top food categories in nutritional psychiatry as we think about how we help our efforts to improve mental health by thinking about nutrition, nutritional quality, and nutritional density. Certainly, those food categories – nuts and legumes, plants, and olive oil – are really what help get us there.

You also gave the students a food hamper. If you were going to be in charge of mental health in Australia and America and you got to give every college freshman a little box with a note, what would be in that box?

Dr. Bayes: I’d want to put everything in that box! It would be full of brightly colored fruits and vegetables, different nuts and seeds, and legumes. It would be full of recipes and ideas of how to cook things and how to prepare really delicious things. It would be full of different herbs and spices and all of those things to get people really excited about food.

Dr. Ramsey: Did the young men pick up on your enthusiasm and excitement around food? Did they begin to adopt some of that, shifting their view of how they saw the food and how they saw that it is related to their depression?

Dr. Bayes: Hopefully. I do think energy is infectious. I’m sure that played a role somewhat, but trying to get them excited about food can be really quite daunting, thinking, I’ve got to change my entire diet and I’ve got to learn to cook and go out and buy groceries. I don’t even know what to do with a piece of salmon. Trying to get them curious, interested, and just reminding them that it’s not all-or-nothing. Make small changes, give it a go, and have fun.

Dr. Ramsey: You also have a unique aspect of your research that you’re interested in male mental health, and that’s not something that’s been widely researched. Can you tell us a little bit about what these men were like in terms of coming into your trial as depressed young men?

Dr. Bayes: In the context of the COVID-19 pandemic, mental health was at the forefront of many people’s minds. They joined the study saying, “I’ve never seen anything like this before. I’ve never seen myself represented in research. I wanted to contribute. I want to add to that conversation because I feel like we are overlooked.”

Dr. Ramsey: I love hearing this notion that maybe young men aren’t quite who we think they are. They are wanting to be seen around their mental health. They can learn to use olive oil and to cook, and they can engage in mental health interventions that work. We just need to ask, give them some food, encourage them, and it makes a big difference.

Jessica Bayes, thank you so much for joining us and sharing some of your research. Everyone, it’s the AMMEND trial. We will drop a link to the trial below so you can take a peek and tell us what you think.

Please, in the comments, let us know what you think about this notion of helping young men with depression through nutritional interventions. Take a peek at the great work that Jessica and Professor Sibbritt from the University of Technology Sydney have published and put out into the scientific literature for us all.

Thanks so much, Jessica. I look forward to seeing you soon.

Dr. Bayes: Thank you.

I’m here with nutritionist Jessica Bayes, who’s at the University of Technology Sydney, and she’s the lead author of the AMMEND trial. [Editor’s note: Since completing her PhD, Bayes is now at Southern Cross University.] The AMMEND trial is our most recent trial in nutritional psychiatry, finding that giving or helping young men eat a Mediterranean diet can be helpful in the treatment of depression.

Jessica, welcome to Medscape.

Jessica Bayes, PhD: Thank you for having me.

The AMMEND Trial

Dr. Ramsey: Thank you for coming on board and helping all of us as clinicians understand some of your research and some of what is suggested by your research – that young men can change their diet and it helped their depression. Tell us a little bit about the AMMEND trial.

Dr. Bayes: The AMMEND trial was a 12-week randomized controlled trial in young men, 18-25 years old, who had diagnosed moderate to severe clinical depression. They had a poor baseline diet and we got them to eat a healthy Mediterranean diet, which improved their symptoms of depression.

Dr. Ramsey: It was a remarkable trial. Jessica, if I recall, you helped individuals improve the Mediterranean dietary pattern score by 8 points on a 14-point scale. That led to a 20-point reduction in their Beck Depression Inventory. Tell us what that looked like on the ground.

Dr. Bayes: It’s a huge improvement. Obviously, they were feeling much better in the end in terms of their depressive symptoms, but we also measured their energy, sleep, and quality of life. Many of them at the end were at a score cutoff that suggests no depression or in remission.

Dr. Ramsey: There were 72 people in your total trial, so 36% in your intervention arm went into full remission.

Dr. Bayes: Which is just amazing.

Dr. Ramsey: It also follows up the SMILES trial, which was a little bit of a different trial. You had two nutritional counseling sessions and the SMILES trial had seven, but in the SMILES trial, 32.3% of the patients went into full remission when they adopted a Mediterranean-style diet.

Jessica, what is the secret that you and your team know? I think many clinicians, especially clinicians who are parents and have teens, are kind of shaking their heads in disbelief. They’ve been telling their kids to eat healthy. What do you guys know about how to help young men change their diet?

How to Aid Adherence to Mediterranean Diet

Dr. Bayes: Prior to starting this, when I would say this idea to people, everyone would say, “Great idea. There’s no way you’re going to get depressed young men to change their diet. Not going to happen.” We went to them and we asked them. We said, “We’re going to do this study. What do you want from us? What resources would you need? How many appointments would you like? What’s too little or too many?”

We really got their feedback on board when we designed the study, and that obviously paid off. We had a personalized approach and we met them where they were at. We gave them the skills, resources, recipes, meal ideas – all those things – so we could really set them up to succeed.

Dr. Ramsey: You were telling me earlier about a few of the dietary changes that you felt made a big difference for these young men. What were those?

Dr. Bayes: Increasing the vegetables, olive oil, and legumes are probably the big ones that most of them were really not doing beforehand. They were really able to take that on board and make significant improvements in those areas.

Dr. Ramsey: These are really some of the top food categories in nutritional psychiatry as we think about how we help our efforts to improve mental health by thinking about nutrition, nutritional quality, and nutritional density. Certainly, those food categories – nuts and legumes, plants, and olive oil – are really what help get us there.

You also gave the students a food hamper. If you were going to be in charge of mental health in Australia and America and you got to give every college freshman a little box with a note, what would be in that box?

Dr. Bayes: I’d want to put everything in that box! It would be full of brightly colored fruits and vegetables, different nuts and seeds, and legumes. It would be full of recipes and ideas of how to cook things and how to prepare really delicious things. It would be full of different herbs and spices and all of those things to get people really excited about food.

Dr. Ramsey: Did the young men pick up on your enthusiasm and excitement around food? Did they begin to adopt some of that, shifting their view of how they saw the food and how they saw that it is related to their depression?

Dr. Bayes: Hopefully. I do think energy is infectious. I’m sure that played a role somewhat, but trying to get them excited about food can be really quite daunting, thinking, I’ve got to change my entire diet and I’ve got to learn to cook and go out and buy groceries. I don’t even know what to do with a piece of salmon. Trying to get them curious, interested, and just reminding them that it’s not all-or-nothing. Make small changes, give it a go, and have fun.

Dr. Ramsey: You also have a unique aspect of your research that you’re interested in male mental health, and that’s not something that’s been widely researched. Can you tell us a little bit about what these men were like in terms of coming into your trial as depressed young men?

Dr. Bayes: In the context of the COVID-19 pandemic, mental health was at the forefront of many people’s minds. They joined the study saying, “I’ve never seen anything like this before. I’ve never seen myself represented in research. I wanted to contribute. I want to add to that conversation because I feel like we are overlooked.”

Dr. Ramsey: I love hearing this notion that maybe young men aren’t quite who we think they are. They are wanting to be seen around their mental health. They can learn to use olive oil and to cook, and they can engage in mental health interventions that work. We just need to ask, give them some food, encourage them, and it makes a big difference.

Jessica Bayes, thank you so much for joining us and sharing some of your research. Everyone, it’s the AMMEND trial. We will drop a link to the trial below so you can take a peek and tell us what you think.

Please, in the comments, let us know what you think about this notion of helping young men with depression through nutritional interventions. Take a peek at the great work that Jessica and Professor Sibbritt from the University of Technology Sydney have published and put out into the scientific literature for us all.

Thanks so much, Jessica. I look forward to seeing you soon.

Dr. Bayes: Thank you.
