Enjoy the ride

Article Type
Changed

She was a 20-year-old barista when we first met, working her way through college.

I was a newly minted attending physician. I’d stopped at the place she worked for coffee on the way to my office. When I got up to the front she was wearing sunglasses and apologized for them. She said she was having bad headaches, and couldn’t get into a doctor she’d been referred to. Feeling bad for her, and needing patients, I handed her my card.

Dr. Allan M. Block

She showed up a few days later, a little nervous as she’d never met a “regular” outside the coffee place before, and had brought her sister along for support.

She was back last week. Now she’s head of human resources for the same chain of local coffee shops. She’s married, with kids, a mortgage, and a minivan.

We were talking about our chance meeting and reminiscing. Her migraines had taken a few medication trials to control, but after a year or 2 we’d found the right one for her and she’s been on it since.

Like many of my longtime patients, she moved past calling me “doctor” long ago. Our one to two visits a year are now more social than medical, chatting about our kids, dogs, and lives.

The same passage of time that brings us from grade school, to medical school, to medical practice takes others along with it. We may not see the changes of days, but when they drop by only once a year it’s obvious. Just like the way we don’t see daily changes in family and friends, but when we look at old pictures we’re shocked by how different they (not to mention ourselves) look.

We all follow the same course around the sun, usually facing the same milestones and similar memories on the trip. Our long-term patients, like distant relatives, may only come by infrequently, so the changes are greater. I’m sure they say the same things about me. “I saw Dr. Block today; boy, he’s really gone gray.”

I don’t mind that (too much) anymore. My thinning, graying, hair (I hope) makes me look a little more distinguished, although my complete lack of fashion sense more than goes the other way.

The river only goes in one direction, carrying us, our patients, and our families, all along with it. We often lose track of time’s effects on us until we see the changes it has brought to another.

It’s always a good reminder to pause and remember to enjoy the ride.

Dr. Block has a solo neurology practice in Scottsdale, Ariz.

Motor function restored in three men after complete paralysis from spinal cord injury

Article Type
Changed

A breakthrough neuromodulation system rapidly restores motor function in patients with a severe spinal cord injury (SCI), new research shows.

The study demonstrated that an epidural electrical stimulation (EES) system developed specifically for spinal cord injuries enabled three men with complete paralysis to stand, walk, cycle, swim, and move their torso within 1 day.

“Thanks to this technology, we have been able to target individuals with the most serious spinal cord injury, meaning those with clinically complete spinal cord injury, with no sensation and no movement in the legs,” Grégoire Courtine, PhD, professor of neuroscience and neurotechnology at the Swiss Federal Institute of Technology, University Hospital Lausanne (Switzerland), and the University of Lausanne, told reporters attending a press briefing.

The study was published online Feb. 7, 2022, in Nature Medicine.
 

More rapid, precise, effective

SCIs involve severed connections between the brain and extremities. To compensate for these lost connections, researchers have investigated stem cell therapy, brain-machine interfaces, and powered exoskeletons.

However, these approaches aren’t yet ready for prime time.

In the meantime, researchers discovered even patients with a “complete” injury may have low-functioning connections and started investigating epidural stimulators designed to treat chronic pain. Recent studies – including three published in 2018 – showed promise for these pain-related stimulators in patients with incomplete SCI.

But using such “repurposed” technology meant the electrode array was relatively narrow and short, “so we could not target all the regions of the spinal cord involving control of leg and trunk movements,” said Dr. Courtine. With the newer technology “we are much more precise, effective, and more rapid in delivering therapy.”

To develop this new approach, the researchers designed a paddle lead with an arrangement of electrodes that targets sacral, lumbar, and low-thoracic dorsal roots involved in leg and trunk movements. They also established a personalized computational framework that allows for optimal surgical placement of this paddle lead.

In addition, they developed software that renders the configuration of individualized activity–dependent stimulation programs rapid, simple, and predictable.

They tested these neurotechnologies in three men with complete sensorimotor paralysis as part of an ongoing clinical trial. The participants, aged 29, 32, and 41 years, suffered an SCI from a motor bike accident 3, 9, and 1 year before enrollment.

All three patients exhibited complete sensorimotor paralysis. They were unable to take any step, and muscles remained quiescent during these attempts.

A neurosurgeon implanted electrodes along the spinal cord of study subjects. Wires from these electrodes were connected to a neurostimulator implanted under the skin in the abdomen.

The men can select different activity-based programs from a tablet that sends signals to the implanted device.
 

Personalized approach

Within a single day of the surgery, the participants were able to stand, walk, cycle, swim, and control trunk movements.

“It was not perfect at the very beginning, but they could train very early on to have a more fluid gait,” said study investigator neurosurgeon Joceylyne Bloch, MD, associate professor, University of Lausanne and University Hospital Lausanne.

At this stage, not all paralyzed patients are eligible for the procedure. Dr. Bloch explained that at least 6 cm of healthy spinal cord under the lesion is needed to implant the electrodes.

“There’s a huge variability of spinal cord anatomy between individuals. That’s why it’s important to study each person individually and to have individual models in order to be precise.”

Researchers envision having “a library of electrode arrays,” added Dr. Courtine. With preoperative imaging of the individual’s spinal cord, “the neurosurgeon can select the more appropriate electrode array for that specific patient.”

Dr. Courtine noted recovery of sensation with the system differs from one individual to another. One study participant, Michel Roccati, now 30, told the briefing he feels a contraction in his muscle during the stimulation.

Currently, only individuals whose injury is more than a year old are included in the study to ensure patients have “a stable lesion” and reached “a plateau of recovery,” said Dr. Bloch. However, animal models show intervening earlier might boost the benefits.

A patient’s age can influence the outcome, as younger patients are likely in better condition and more motivated than older patients, said Dr. Bloch. However, she noted patients closing in on 50 years have responded well to the therapy.

Such stimulation systems may prove useful in treating conditions typically associated with SCI, such as hypertension and bladder control, and perhaps also in patients with Parkinson’s disease, said Dr. Courtine.

The researchers plan to conduct another study that will include a next-generation pulse generator with features that make the stimulation even more effective and user friendly. A voice recognition system could eventually be connected to the system.

“The next step is a minicomputer that you implant in the body that communicates in real time with an external iPhone,” said Dr. Courtine.

ONWARD Medical, which developed the technology, has received a breakthrough device designation from the Food and Drug Administration. The company is in discussions with the FDA to carry out a clinical trial of the device in the United States.
 

 

 

A ‘huge step forward’

Peter J. Grahn, PhD, assistant professor, department of physical medicine and rehabilitation and department of neurologic surgery, Mayo Clinic, Rochester, Minn., an author of one of the 2018 studies, said this technology “is a huge step forward” and “really pushes the field.”

Compared with the device used in his study that’s designed to treat neuropathic pain, this new system “is much more capable of dynamic stimulation,” said Dr. Grahn. “You can tailor the stimulation based on which area of the spinal cord you want to target during a specific function.”

There has been “a lot of hope and hype” recently around stem cells and biological molecules that were supposed to be “magic pills” to cure spinal cord dysfunction, said Dr. Grahn. “I don’t think this is one of those.”

However, he questioned the researchers’ use of the word “walking.”

“They say independent stepping or walking is restored on day 1, but the graphs show day 1 function is having over 60% of their body weight supported when they’re taking these steps,” he said.

In addition, the “big question” is how this technology can “be distilled down” into an approach “applicable across rehabilitation centers,” said Dr. Grahn.

The study was supported by numerous organizations, including ONWARD Medical. Dr. Courtine and Dr. Bloch hold various patents in relation with the present work. Dr. Courtine is a consultant with ONWARD Medical, and he and Dr. Bloch are shareholders of ONWARD Medical, a company with direct relationships with the presented work. Dr. Grahn reported no relevant financial relationships.

Drinking a risk factor for epilepsy?

Article Type
Changed

Drinking alcohol is linked to an increased risk of new-onset epilepsy, with greater consumption tied to greater risk, but more research is needed before any definitive conclusions can be drawn.

Results of an updated meta-analysis are consistent with those of a previous meta-analysis but contrast with some prior cohort studies.

“Further large cohort studies of the general population are required to assert a definite causal relationship between alcohol consumption and epilepsy and to identify a potential threshold,” Yun Hak Kim, MD, PhD, departments of biomedical informatics and anatomy, Pusan (South Korea) National University, said in a press release.

The study was published online Jan. 11, 2022, in Drug and Alcohol Dependence.
 

Conflicting findings

Much of the research into the impact of alcohol on epilepsy risk has focused on provoked seizures related to alcohol intoxication or withdrawal, but few studies have investigated the effect of alcohol on unprovoked seizures. In addition, the research in this area has been conflicting.

A 2010 meta-analysis that included six case-control studies showed alcohol users had an increased risk of unprovoked seizure or epilepsy with a pooled relative risk of 2.19 (95% confidence interval, 1.82-2.63). This analysis also showed a dose-dependent relationship with relative risks increasing with more grams of alcohol consumed daily.

However, some recent large cohort studies showed that moderate alcohol consumption was associated with a lower risk of epilepsy.

The updated meta-analysis included eight studies – three cohort studies not included in the previous meta-analysis and five case-control studies.

The study excluded two case-control studies included in the previous meta-analysis. One of these studies used duplicated data, and the other included epilepsy patients and did not present results of subgroup analysis for patients experiencing their first seizure.

Results of the new analysis showed the pooled odds ratio for newly diagnosed epilepsy was 1.70 (95% CI, 1.16-2.49) in alcohol users versus nondrinkers.

A dose-response analysis of case-control studies carried out using the cubic spline analysis showed a significant positive dose-response relationship. A dose-response graph showed a steep increase in risk above about 150 g/day and 250 g/day of alcohol consumption.

However, a subgroup analysis showed that epilepsy risk was only found in the case-control studies. In fact, two of the three cohort studies showed that alcohol consumption was associated with a lower risk of epilepsy, although this was not significant.

Cohort studies often include more control subjects and longer follow-up periods and are less prone to bias, such as selection and recall biases, the investigators noted.

“Therefore, cohort studies usually provide a stronger association between exposure and disease than case-control studies, despite having limitations for diseases with low incidence levels,” they wrote.
 

More research needed

The researchers added that most case-control studies included in the new meta-analysis assessed alcohol consumption only in the 6 months prior to the onset of seizures. Research shows it usually takes heavy drinkers 5 or more years to develop repetitive unprovoked seizures.

“Considering these temporal relationships and differences in study design, alcohol may not actually increase the risk of epilepsy, as seen in our subgroup analysis for cohort studies,” the investigators wrote.

They noted that the cohort studies in the meta-analysis were variously limited to young women, elderly patients, and post–subdural hematoma patients. “This limitation makes it difficult to confirm or generalize the results of the subgroup analysis.”

To resolve this “discrepancy,” further large cohort studies of the general population over a longer period are needed, the investigators wrote.

Examining the risk of bias within studies, the authors evaluated three cohort studies as “good” quality. Of the case-control studies, they rated two as “good,” one as “fair,” and two as “poor.”

For primary prevention, an assessment of the risk of alcohol consumption in various clinical situations, such as the time relation of alcohol consumption with seizures, will be important, lead author Kyoung Nam Woo, department of neurology, Pusan National University, said in the release.

“To increase the applicability to the general population, future studies should be conducted in which the potential confounders such as age, sex, and smoking have been adjusted.”

Commenting on the study, Jacqueline French, MD, professor, New York University Comprehensive Epilepsy Center, echoed the authors in noting a number of weaknesses in the study.

The analysis was unable to exclude alcohol withdrawal seizures. Also, while some studies suggested a positive relationship, others suggested a negative relationship, she said. “The authors suggest further work is needed before a definitive determination is made, and I agree.”

The study received funding from the Medical Research Center Program, the Basic Science Research Program, and the Collaborative Genome Program for Fostering New Post-Genome Industry through a National Research Foundation of Korea grant funded by the Korean government. The authors disclosed no relevant financial relationships.

Results of an updated meta-analysis are consistent with those of a previous meta-analysis but contrast with some prior cohort studies.

“Further large cohort studies of the general population are required to assert a definite causal relationship between alcohol consumption and epilepsy and to identify a potential threshold,” Yun Hak Kim, MD, PhD, departments of biomedical informatics and anatomy, Pusan (South Korea) National University, said in a press release.

The study was published online Jan. 11, 2022, in Drug and Alcohol Dependence.
 

Conflicting findings

Much of the research into the impact of alcohol on epilepsy risk has focused on provoked seizures related to alcohol intoxication or withdrawal, but few studies have investigated the effect of alcohol on unprovoked seizures. In addition, the research in this area has been conflicting.

A 2010 meta-analysis that included six case-control studies showed alcohol users had an increased risk of unprovoked seizure or epilepsy with a pooled relative risk of 2.19 (95% confidence interval, 1.82-2.63). This analysis also showed a dose-dependent relationship with relative risks increasing with more grams of alcohol consumed daily.

However, some recent large cohort studies showed that moderate alcohol consumption was associated with a lower risk of epilepsy.

The updated meta-analysis included eight studies – three cohort studies not included in the previous meta-analysis and five case-control studies.

The study excluded two case-control studies included in the previous meta-analysis. One of these studies used duplicated data, and the other included epilepsy patients and did not present results of subgroup analysis for patients experiencing their first seizure.

Results of the new analysis showed the pooled odds ratio for newly diagnosed epilepsy was 1.70 (95% CI, 1.16-2.49) in alcohol users versus nondrinkers.

A dose-response analysis of case-control studies carried out using the cubic spline analysis showed a significant positive dose-response relationship. A dose-response graph showed a steep increase in risk above about 150 g/day and 250 g/day of alcohol consumption.

However, a subgroup analysis showed that epilepsy risk was only found in the case-control studies. In fact, two of the three cohort studies showed that alcohol consumption was associated with a lower risk of epilepsy, although this was not significant.

Cohort studies often include more control subjects and longer follow-up periods and are less prone to bias, such as selection and recall biases, the investigators noted.

“Therefore, cohort studies usually provide a stronger association between exposure and disease than case-control studies, despite having limitations for diseases with low incidence levels,” they wrote.
 

More research needed

The researchers added that most case-control studies included in the new meta-analysis assessed alcohol consumption only in the 6 months prior to the onset of seizures. Research shows it usually takes heavy drinkers 5 or more years to develop repetitive unprovoked seizures.

“Considering these temporal relationships and differences in study design, alcohol may not actually increase the risk of epilepsy, as seen in our subgroup analysis for cohort studies,” the investigators wrote.

They noted that the cohort studies in the meta-analysis were variously limited to young women, elderly patients, and post–subdural hematoma patients. “This limitation makes it difficult to confirm or generalize the results of the subgroup analysis.”

To resolve this “discrepancy,” further large cohort studies of the general population over a longer period are needed, the investigators wrote.

Examining the risk of bias within studies, the authors evaluated three cohort studies as “good” quality. Of the case-control studies, they rated two as “good,” one as “fair,” and two as “poor.”

For primary prevention, an assessment of the risk of alcohol consumption in various clinical situations, such as the time relation of alcohol consumption with seizures, will be important, lead author Kyoung Nam Woo, department of neurology, Pusan National University, said in the release.

“To increase the applicability to the general population, future studies should be conducted in which the potential confounders such as age, sex, and smoking have been adjusted.”

Commenting on the study, Jacqueline French, MD, professor, New York University Comprehensive Epilepsy Center, echoed the authors in noting a number of weaknesses in the study.

The analysis was unable to exclude alcohol withdrawal seizures. Also, while some studies suggested a positive relationship, others suggested a negative relationship, she said. “The authors suggest further work is needed before a definitive determination is made, and I agree.”

The study received funding from the Medical Research Center Program, the Basic Science Research Program, and the Collaborative Genome Program for Fostering New Post-Genome Industry through a National Research Foundation of Korea grant funded by the Korean government. The authors disclosed no relevant financial relationships.

Dietary fat tied to better cognition in older adults

Article Type
Changed

 

Dietary intake of polyunsaturated fatty acids (PUFA), particularly omega 6, is associated with improved cognitive function in older adults, new research suggests.

The study provides important “pieces of the puzzle” of the diet and cognition connection, but the results aren’t “ready for prime time,” study investigator Roger S. McIntyre, MD, professor of psychiatry and pharmacology, University of Toronto, said in an interview.

“I don’t think we’re there yet when it comes to recommending supplementation to the general public,” said Dr. McIntyre, adding a larger “more compelling study” is needed.

The study was published online Jan. 14 in The American Journal of Geriatric Psychiatry.
 

Clinically meaningful?

Research shows that 25%-50% of community-dwelling adults aged 65-85 years have some cognitive impairment. Other evidence indicates cognition is affected by dietary fat intake.

Many lines of research show that alterations in lipid homeostasis can cause brain dysfunction, said Dr. McIntyre. “This shouldn’t surprise us because our brain is made up of protein, water, and fat.”

This new analysis used combined data from the 2011-2012 and 2013-2014 cycles of the National Health and Nutrition Examination Survey (NHANES), a series of ongoing cross-sectional surveys conducted by the Centers for Disease Control and Prevention. The data are collected in two phases, an in-home face-to-face interview and a physical examination.

Researchers obtained dietary intake information through two 24-hour dietary recall interviews. Dietary information included total energy (kcal/d), intakes in grams per day (g/d) of total fat, saturated fatty acid (SFAT), monounsaturated fatty acid (MUFA), PUFA, total omega-3 and total omega-6 fatty acids, and milligrams per day (mg/d) of cholesterol.

For cognitive function, the researchers used total and delayed recall scores of the Consortium to Establish a Registry for Alzheimer’s Disease (CERAD), the animal fluency test, and the digit symbol substitution test (DSST).

The study included 2,253 adults aged 60 years and older (mean age, 69.4 years) and 51% were non-Hispanic White individuals.

After adjustment for age, sex, race/ethnicity, educational attainment, smoking status, alcohol consumption, income, and total energy, dietary intake of PUFA and omega-6 fatty acid was positively associated with DSST.

The DSST score increased about 0.06 standard deviation (SD) (about 1 score) with each SD increase in these fatty acids (8.8 g/d for PUFA and 7.9 g/d for omega-6) (P values were .02 for PUFA and .01 for omega-6).

However, it’s unclear what an improvement of 1 DSST score means clinically, said Dr. McIntyre. “The P value is significant, but how does that translate? Does this mean a person can now think more clearly or function better?”
 

 

 

‘Million dollar question’ remains unanswered

The fact that omega-6, considered neuroinflammatory, was associated with improved DSST score illustrates the complexity of this field, said Dr. McIntyre.

“We’re learning that when it comes to inflammation, many of the molecules in our brain that are implicated as anti-inflammatory can also be pro-inflammatory, so bad guys can be good guys and good guys can be bad guys.”

It speaks to the notion of homeostasis, he added. “Just like a seesaw; when you push this part down, that part goes up.”

The analysis showed the animal fluency score increased about 0.05 SD (around 0.3 score) with each SD (1.1 g/d) increase in dietary intake of omega-3.

There were no significant associations between other dietary fat intake and cognitive performance.

The researchers investigated the role of oxidative stress and antioxidant biomarkers (gamma glutamyl transpeptidase [GGT], bilirubin, uric acid, and vitamin D).

Cells produce oxidative radicals that are normally “mopped up” by our “innate antioxidant capability,” said Dr. McIntyre. “But in states of cognitive impairment, these oxidative stress markers accumulate and they exceed what the normal innate response is able to manage.”

The study showed GGT levels decreased with increased PUFA and omega-6 fatty acid intakes; levels of bilirubin decreased with increase in most dietary fat intakes; uric acid levels decreased with MUFA intake and omega-6/omega-3 ratio; and vitamin D levels increased with omega-3 fatty acid intake but decreased with SFAT intake.

Causal mediation analysis showed the association between dietary intake of fatty acids and DSST performance was partially mediated by GGT levels. However, Dr. McIntyre emphasized that this does not prove causality.

“The million dollar question is, is this the sole explanation for the association? In other words, is it the oxidative stress that caused the cognitive impairment and therefore correcting it improved it, or is it the case that oxidative stress is a proxy of other activities that are also taking place?”
 

 

 

A ‘plausible’ link

In an editorial, Candida Rebello, PhD, of the department of integrated physiology and molecular medicine at Pennington Biomedical Research Center, Baton Rouge, La., said the finding that omega-3 and omega-6 fatty acids are positively associated with cognition in older adults makes some sense.

She noted that aging is associated with an overt inflammatory phenotype, and evidence shows these fatty acids are precursors for bioactive molecules that play a role in self-limiting the acute inflammatory response.

Dr. Rebello said the positive association of omega-6 fatty acid with cognition shown in this study contrasts with the “common belief” that increasing dietary intake of these fatty acids enhances inflammation, but agreed the association is “plausible.”

She said it’s “essential” to determine “the underlying mechanisms that regulate the diverse features of inflammation and sort out the processes that protect from neuronal damage and those that contribute towards it.”

She noted the ratio of omega-6 to omega-3 is about 15:1 in the present day Western diet, as opposed to a 1:1 ratio in diets of the past. Omega-3 fatty acids are found in fish oil supplements and fatty fish like mackerel and salmon, while cereal, grains, and vegetable oil are sources of omega-6.

Attaining a measure of balance of fatty acids in the diet may be a “prudent approach,” said Dr. Rebello. “Substituting some meat entrées with fatty fish and polyunsaturated vegetable oils with monounsaturated fats such as olive oil are small changes that are likely to garner adherence.”

Dr. Rebello noted that the study used NHANES food intake data, which rely on participant self-report and so may not be accurate.

The study received funding from the MOE (Ministry of Education in China) Project of Humanities and Social Sciences and the Research Startup Fund of Southwest University. Dr. McIntyre has received research grant support from CIHR/GACD/Chinese National Natural Research Foundation and speaker/consultation fees from Lundbeck, Janssen, Purdue, Pfizer, Otsuka, Takeda, Neurocrine, Sunovion, Bausch Health, Novo Nordisk, Kris, Sanofi, Eisai, Intra-Cellular, NewBridge Pharmaceuticals, and AbbVie.

Boosted Americans 97 times less likely to die of COVID-19 than unvaccinated

Article Type
Changed

Americans who have received a COVID-19 booster shot are 97 times less likely to die from the coronavirus than those who aren’t vaccinated, according to a new update from the CDC.

In addition, fully vaccinated Americans — meaning those with up to two doses, but no booster — are 14 times less likely to die from COVID-19 than unvaccinated people.

“These data confirm that vaccination and boosting continues to protect against severe illness and hospitalization, even during the Omicron surge,” Rochelle Walensky, MD, director of the CDC, said during a briefing by the White House COVID-19 Response Team.

“If you are not up to date on your COVID-19 vaccinations, you have not optimized your protection against severe disease and death, and you should get vaccinated and boosted if you are eligible,” she said.

Dr. Walensky presented the latest numbers on Feb. 2 based on reports from 25 jurisdictions in early December. The number of average weekly deaths for those who were unvaccinated was 9.7 per 100,000 people, as compared with 0.7 of those who were vaccinated and 0.1 of those who had received a booster.

“The data are really stunningly obvious why a booster is really very important,” Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, said during the briefing.

Dr. Fauci also encouraged vaccination for those who are pregnant and couples who may want to conceive in the near feature. He highlighted two recent studies that found vaccination in either partner didn’t affect fertility, including in vitro fertilization.

Meanwhile, fertility fell temporarily among men who were infected with the coronavirus. Couples were 18% less likely to conceive if the male partner had contracted the coronavirus within 60 days before a menstrual cycle.

“New data adds to previous studies that indicate that COVID-19 vaccination does not negatively impact fertility,” Dr. Fauci said. “Vaccination is recommended for people who are trying to get pregnant now or might become pregnant in the future, as well as their partners.”

About 80% of eligible Americans have received at least one vaccine dose, and 68% are fully vaccinated, according to the latest CDC data. About 51% of those who are eligible for a booster dose have received one.

The FDA could authorize the Pfizer vaccine for children under age 5 later this month. When that happens, about 18 million children will qualify for a shot, Jeff Zients, coordinator of the White House COVID-19 Response Team, said during the briefing. The Biden administration is already working on distribution plans for the shot for young kids, he added.

“We’ll be ready to start getting shots in arms soon after FDA and CDC make their decisions,” he said.

“These data confirm that vaccination and boosting continues to protect against severe illness and hospitalization, even during the Omicron surge,” Rochelle Walensky, MD, director of the CDC, said during a briefing by the White House COVID-19 Response Team.

“If you are not up to date on your COVID-19 vaccinations, you have not optimized your protection against severe disease and death, and you should get vaccinated and boosted if you are eligible,” she said.

Dr. Walensky presented the latest numbers on Feb. 2 based on reports from 25 jurisdictions in early December. The number of average weekly deaths for those who were unvaccinated was 9.7 per 100,000 people, as compared with 0.7 of those who were vaccinated and 0.1 of those who had received a booster.

“The data are really stunningly obvious why a booster is really very important,” Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, said during the briefing.

Dr. Fauci also encouraged vaccination for those who are pregnant and couples who may want to conceive in the near feature. He highlighted two recent studies that found vaccination in either partner didn’t affect fertility, including in vitro fertilization.

Meanwhile, fertility fell temporarily among men who were infected with the coronavirus. Couples were 18% less likely to conceive if the male partner had contracted the coronavirus within 60 days before a menstrual cycle.

“New data adds to previous studies that indicate that COVID-19 vaccination does not negatively impact fertility,” Dr. Fauci said. “Vaccination is recommended for people who are trying to get pregnant now or might become pregnant in the future, as well as their partners.”

About 80% of eligible Americans have received at least one vaccine dose, and 68% are fully vaccinated, according to the latest CDC data. About 51% of those who are eligible for a booster dose have received one.

The FDA could authorize the Pfizer vaccine for children under age 5 later this month. When that happens, about 18 million children will qualify for a shot, Jeff Zients, coordinator of the White House COVID-19 Response Team, said during the briefing. The Biden administration is already working on distribution plans for the shot for young kids, he added.

“We’ll be ready to start getting shots in arms soon after FDA and CDC make their decisions,” he said.

Antibody mix may prevent COVID symptoms in some asymptomatic people

Article Type
Changed

A subcutaneous antibody combination of casirivimab and imdevimab given to asymptomatic people who tested positive for SARS-CoV-2 significantly lowered the incidence of symptomatic COVID-19 over 28 days, new research shows.

Results of the study by Meagan P. O’Brien, MD, from Regeneron Pharmaceuticals and one of the study’s funders, and coauthors were published online Jan. 14, 2022, in an original investigation in JAMA.

The results suggest new potential for monoclonal antibodies currently used for postexposure prophylaxis and treatment of symptomatic SARS-CoV-2. It has not been clear whether monoclonal antibodies can benefit people with asymptomatic SARS-CoV-2 infection.

The trial included 314 participants (mean age, 41 years; 51.6% women). Of the participants, 310 (99.7%) completed the efficacy assessment period, and 204 were asymptomatic and tested negative at baseline and were included in the primary efficacy analysis.

The subcutaneous combination of casirivimab and imdevimab, 1,200 mg (600 mg each), significantly prevented progression to symptomatic disease (29/100 [29.0%] vs. 44/104 [42.3%] with placebo; odds ratio, 0.54 [95% confidence interval, 0.30-0.97]; P = .04; absolute risk difference, −13.3% [95% CI, −26.3% to −0.3%]).

These results were part of a randomized, double-blind, placebo-controlled, phase 3 trial of close household contacts of a SARS-CoV-2–infected person at 112 sites in the United States, Romania, and Moldova. They were enrolled between July 13, 2020, and Jan. 28, 2021; follow-up ended March 11, 2021.

Asymptomatic people at least 12 years old were eligible if identified within 96 hours of index case positive test collection and were randomly assigned 1:1 to receive one dose of subcutaneous casirivimab and imdevimab (n = 158), or placebo (n = 156).

COVID-19 vaccination was prohibited before enrollment but was allowed after completing the 28-day efficacy assessment period.
 

Caution warranted

In an accompanying editorial, however, Jonathan Z. Li, MD, Brigham and Women’s Hospital and Harvard Medical School, both in Boston, and Rajesh T. Gandhi, MD, Massachusetts General Hospital, Boston, and Harvard Medical School, urged caution in interpreting the results.

They wrote that, although monoclonal antibodies are generally used in individuals at high risk for severe COVID-19, this study population was less vulnerable, with an average age of 41, and 30% had no risk for the disease.

“Of the remainder, the most common risk factor was being overweight (which confers less risk than other factors),” the editorialists wrote.

They pointed out, as did the study authors, that enrollment came before the emergence of the Delta and Omicron variants, and that both casirivimab and imdevimab maintain their activity against Delta but not against Omicron.

“While prevention of symptomatic infection has benefits,” they wrote, “the primary goal of monoclonal antibody therapy is to prevent progression to severe disease; however, this trial was unable to assess this outcome because there were only three hospitalizations (all in the placebo group). Also, this study was conducted prior to widespread COVID-19 vaccination; whether monoclonal antibodies have the same benefit in people who have breakthrough infection after vaccination is not known.”

The editorialists highlighted the subcutaneous delivery in this study.

They wrote that Dr. O’Brien and coauthors provide evidence that subcutaneous administration is effective in infected individuals. “However, high serum monoclonal antibody levels are achieved more quickly after intravenous administration than following subcutaneous injection; it is unknown whether intravenous administration might have led to even greater efficacy for individuals with asymptomatic SARS-CoV-2 infection.”

The authors of the study also add that, despite efforts to recruit non-White participants, relatively few non-White people were enrolled. Additionally, few adolescents were enrolled.

The sample size was also relatively small, they acknowledge, because of a study design in which the infection status of asymptomatic participants was not confirmed at inclusion.

Several of the authors are employees/stockholders of Regeneron, and have a patent pending, which has been licensed and is receiving royalties. The study was supported by Regeneron and F. Hoffmann–La Roche. This trial was conducted jointly with the National Institute of Allergy and Infectious Diseases and the National Institutes of Health. The CoVPN (COVID-19 Prevention Network) is supported by cooperative agreement awards from the NIAID and NIH.

If you give a mouse a genetically engineered bitcoin wallet

Article Type

The world’s most valuable mouse

You’ve heard of Mighty Mouse. Now say hello to the world’s newest mouse superhero, Crypto-Mouse! After being bitten by a radioactive cryptocurrency investor, Crypto-Mouse can tap directly into the power of the blockchain itself, allowing it to perform incredible, death-defying feats of strength!

We’re going to stop right there before Crypto-Mouse gains entry into the Marvel cinematic universe. Let’s rewind to the beginning, because that’s precisely where this crazy scheme is at. In late January, a new decentralized autonomous organization, BitMouseDAO, launched to enormous … -ly little fanfare, according to Vice. Two investors as of Jan. 31. But what they lack in money they make up for in sheer ambition.

Clker-Free-Vector-Images/Pixabay

BitMouseDAO’s $100 million dollar idea is to genetically engineer mice to carry bitcoin, the first cryptocurrency and one of the most valuable. This isn’t as crazy an idea as it sounds since DNA can be modified to store information, potentially even bitcoin information. Their plan is to create a private bitcoin wallet, which will be stored in the mouse DNA, and purchase online bitcoin to store in this wallet.

BitMouseDAO, being a “collection of artists,” plans to partner with a lab to translate its private key into a specific DNA sequence to be encoded into the mice during fertilization; or, if that doesn’t work, inject them with a harmless virus that carries the key.

Since these are artists, their ultimate plan is to use their bitcoin mice to make NFTs (scratch that off your cryptocurrency bingo card) and auction them off to people. Or, as Vice put it, BitMouseDAO essentially plans to send preserved dead mice to people. Artistic dead mice! Artistic dead mice worth millions! Maybe. Even BitMouseDAO admits bitcoin could be worthless by the time the project gets off the ground.

If this all sounds completely insane, that’s because it is. But it also sounds crazy enough to work. Now, if you’ll excuse us, we’re off to write a screenplay about a scrappy group of high-tech thieves who steal a group of genetically altered bitcoin mice to sell for millions, only to keep them as their adorable pets. Trust us Hollywood, it’ll make millions!
 

Alcoholic monkeys vs. the future of feces

Which is more important, the journey or the destination? Science is all about the destination, yes? Solving the problem, saving a life, expanding horizons. That’s science. Or is it? The scientific method is a process, so does that make it a journey?

Amandad/Pixabay

For us, today’s journey begins at the University of Iowa, where investigators are trying to reduce alcohol consumption. A worthy goal, and they seem to have made some progress by targeting a liver hormone called fibroblast growth factor 21 (FGF21). But we’re more interested in the process right now, so bring on the alcoholic monkeys. And no, that’s not a death metal/reggae fusion band. Should be, though.

“The vervet monkey population is [composed] of alcohol avoiders, moderate alcohol drinkers, and a group of heavy drinkers,” Matthew Potthoff, PhD, and associates wrote in Cell Metabolism. When this particular bunch of heavy-drinking vervets were given FGF21, they consumed 50% less alcohol than did vehicle-treated controls, so mission accomplished.

Maybe it could be a breakfast cereal. Who wouldn’t enjoy a bowl of alcoholic monkeys in the morning?

And after breakfast, you might be ready for a digitized bowel movement, courtesy of researchers at University of California, San Diego. They’re studying ulcerative colitis (UC) by examining the gut microbiome, and their “most useful biological sample is patient stool,” according to a written statement from the university.

“Once we had all the technology to digitize the stool, the question was, is this going to tell us what’s happening in these patients? The answer turned out to be yes,” co-senior author Rob Knight, PhD, said in the statement. “Digitizing fecal material is the future.” The road to UC treatment, in other words, is paved with digital stool.

About 40% of the UC patients had elevated protease levels, and their high-protease feces were then transplanted into germ-free mice, which subsequently developed colitis and were successfully treated with protease inhibitors. And that is our final destination.

As our revered founder and mentor, Josephine Lotmevich, used to say, an alcoholic monkey in the hand is worth a number 2 in the bush.
 

 

 

Raise a glass to delinquency

You wouldn’t think that a glass of water could lead to a life of crime, but a recent study suggests just that.

PxHere

Children exposed to lead in their drinking water during their early years had a 21% higher risk of delinquency after the age of 14 years and a 38% higher risk of having a record for a serious complaint, Jackie MacDonald Gibson and associates said in a statement on Eurekalert.

Data for the study came from Wake County, N.C., which includes rural areas, wealthy exurban developments, and predominantly Black communities. The investigators compared the blood lead levels for children tested between 1998 and 2011 with juvenile delinquency reports of the same children from the N.C. Department of Public Safety.

The main culprit, they found, was well water. Blood lead levels were 11% higher in the children whose water came from private wells, compared with children using community water. About 13% of U.S. households rely on private wells, which are not regulated under the Safe Drinking Water Act, for their water supply.

The researchers said there is an urgent need for better drinking-water solutions in communities that rely on well water, whether it be through subsidized home filtration or infrastructure redevelopment.

An earlier study had estimated that preventing just one child from entering the adult criminal justice system would save $1.3 to $1.5 million in 1997 dollars. That’s about $2.2 to $2.5 million dollars today!

If you do the math, it’s not hard to see what’s cheaper (and healthier) in the long run.
 

A ‘dirty’ scam

Another one? This is just getting sad. You’ve probably heard of muds and clays being good for the skin and maybe you’ve gone to a spa and sat in a mud bath, but would you believe it if someone told you that mud can cure all your ailments? No? Neither would we. Senatorial candidate Beto O’Rourke was definitely someone who brought this strange treatment to light, but it seems like this is something that has been going on for years, even before the pandemic.

Nandan/Pixahive

A company called Black Oxygen Organics (BOO) was selling “magic dirt” for $110 per 4-ounce package. It claimed the dirt was high in fulvic acid and humic acid, which are good for many things. They were, however, literally getting this mud from bogs with landfills nearby, Mel magazine reported.

That doesn’t sound appealing at all, but wait, there’s more. People were eating, drinking, bathing, and feeding their families this sludge in hopes that they would be cured of their ailments. A lot of people jumped aboard the magic dirt train when the pandemic arose, but it quickly became clear that this mud was not as helpful as BOO claimed it to be.

“We began to receive inquiries and calls on our website with people having problems and issues. Ultimately, we sent the products out for independent testing, and then when that came back and showed that there were toxic heavy metals [lead, arsenic, and cadmium among them] at an unsafe level, that’s when we knew we had to act,” Atlanta-based attorney Matt Wetherington, who filed a federal lawsuit against BOO, told Mel.

After a very complicated series of events involving an expose by NBC, product recalls, extortion claims, and grassroots activism, BOO was shut down by both the Canadian and U.S. governments.

As always, please listen only to health care professionals when you wish to use natural remedies for illnesses and ailments.

That doesn’t sound appealing at all, but wait, there’s more. People were eating, drinking, bathing, and feeding their families this sludge in hopes that they would be cured of their ailments. A lot of people jumped aboard the magic dirt train when the pandemic arose, but it quickly became clear that this mud was not as helpful as BOO claimed it to be.

“We began to receive inquiries and calls on our website with people having problems and issues. Ultimately, we sent the products out for independent testing, and then when that came back and showed that there were toxic heavy metals [lead, arsenic, and cadmium among them] at an unsafe level, that’s when we knew we had to act,” Atlanta-based attorney Matt Wetherington, who filed a federal lawsuit against BOO, told Mel.

After a very complicated series of events involving an expose by NBC, product recalls, extortion claims, and grassroots activism, BOO was shut down by both the Canadian and U.S. governments.

The world’s most valuable mouse

You’ve heard of Mighty Mouse. Now say hello to the world’s newest mouse superhero, Crypto-Mouse! After being bitten by a radioactive cryptocurrency investor, Crypto-Mouse can tap directly into the power of the blockchain itself, allowing it to perform incredible, death-defying feats of strength!

We’re going to stop right there before Crypto-Mouse gains entry into the Marvel cinematic universe. Let’s rewind to the beginning, because that’s precisely where this crazy scheme is at. In late January, a new decentralized autonomous organization, BitMouseDAO, launched to enormous … -ly little fanfare, according to Vice. Two investors as of Jan. 31. But what they lack in money they make up for in sheer ambition.

BitMouseDAO’s $100 million dollar idea is to genetically engineer mice to carry bitcoin, the first cryptocurrency and one of the most valuable. This isn’t as crazy an idea as it sounds since DNA can be modified to store information, potentially even bitcoin information. Their plan is to create a private bitcoin wallet, which will be stored in the mouse DNA, and purchase online bitcoin to store in this wallet.

BitMouseDAO, being a “collection of artists,” plans to partner with a lab to translate its private key into a specific DNA sequence to be encoded into the mice during fertilization; or, if that doesn’t work, inject them with a harmless virus that carries the key.

Since these are artists, their ultimate plan is to use their bitcoin mice to make NFTs (scratch that off your cryptocurrency bingo card) and auction them off to people. Or, as Vice put it, BitMouseDAO essentially plans to send preserved dead mice to people. Artistic dead mice! Artistic dead mice worth millions! Maybe. Even BitMouseDAO admits bitcoin could be worthless by the time the project gets off the ground.

If this all sounds completely insane, that’s because it is. But it also sounds crazy enough to work. Now, if you’ll excuse us, we’re off to write a screenplay about a scrappy group of high-tech thieves who steal a group of genetically altered bitcoin mice to sell for millions, only to keep them as their adorable pets. Trust us Hollywood, it’ll make millions!
 

Alcoholic monkeys vs. the future of feces

Which is more important, the journey or the destination? Science is all about the destination, yes? Solving the problem, saving a life, expanding horizons. That’s science. Or is it? The scientific method is a process, so does that make it a journey?

Amandad/Pixabay

For us, today’s journey begins at the University of Iowa, where investigators are trying to reduce alcohol consumption. A worthy goal, and they seem to have made some progress by targeting a liver hormone called fibroblast growth factor 21 (FGF21). But we’re more interested in the process right now, so bring on the alcoholic monkeys. And no, that’s not a death metal/reggae fusion band. Should be, though.

“The vervet monkey population is [composed] of alcohol avoiders, moderate alcohol drinkers, and a group of heavy drinkers,” Matthew Potthoff, PhD, and associates wrote in Cell Metabolism. When this particular bunch of heavy-drinking vervets were given FGF21, they consumed 50% less alcohol than did vehicle-treated controls, so mission accomplished.

Maybe it could be a breakfast cereal. Who wouldn’t enjoy a bowl of alcoholic monkeys in the morning?

And after breakfast, you might be ready for a digitized bowel movement, courtesy of researchers at University of California, San Diego. They’re studying ulcerative colitis (UC) by examining the gut microbiome, and their “most useful biological sample is patient stool,” according to a written statement from the university.

“Once we had all the technology to digitize the stool, the question was, is this going to tell us what’s happening in these patients? The answer turned out to be yes,” co-senior author Rob Knight, PhD, said in the statement. “Digitizing fecal material is the future.” The road to UC treatment, in other words, is paved with digital stool.

About 40% of the UC patients had elevated protease levels, and their high-protease feces were then transplanted into germ-free mice, which subsequently developed colitis and were successfully treated with protease inhibitors. And that is our final destination.

As our revered founder and mentor, Josephine Lotmevich, used to say, an alcoholic monkey in the hand is worth a number 2 in the bush.
 

 

 

Raise a glass to delinquency

You wouldn’t think that a glass of water could lead to a life of crime, but a recent study suggests just that.

PxHere

Children exposed to lead in their drinking water during their early years had a 21% higher risk of delinquency after the age of 14 years and a 38% higher risk of having a record for a serious complaint, Jackie MacDonald Gibson and associates said in a statement on Eurekalert.

Data for the study came from Wake County, N.C., which includes rural areas, wealthy exurban developments, and predominantly Black communities. The investigators compared the blood lead levels for children tested between 1998 and 2011 with juvenile delinquency reports of the same children from the N.C. Department of Public Safety.

The main culprit, they found, was well water. Blood lead levels were 11% higher in the children whose water came from private wells, compared with children using community water. About 13% of U.S. households rely on private wells, which are not regulated under the Safe Drinking Water Act, for their water supply.

The researchers said there is an urgent need for better drinking-water solutions in communities that rely on well water, whether it be through subsidized home filtration or infrastructure redevelopment.

An earlier study had estimated that preventing just one child from entering the adult criminal justice system would save $1.3 to $1.5 million in 1997 dollars. That’s about $2.2 to $2.5 million dollars today!

If you do the math, it’s not hard to see what’s cheaper (and healthier) in the long run.
 

A ‘dirty’ scam

Another one? This is just getting sad. You’ve probably heard of muds and clays being good for the skin and maybe you’ve gone to a spa and sat in a mud bath, but would you believe it if someone told you that mud can cure all your ailments? No? Neither would we. Senatorial candidate Beto O’Rourke was definitely someone who brought this strange treatment to light, but it seems like this is something that has been going on for years, even before the pandemic.

10 things not to do in a medical board hearing

Article Type
Changed

A Florida doctor told his patient her test result would be available in 3-4 days. When the patient didn’t hear back, she called the practice several times, but she didn’t receive a return call. So she filed a complaint against the doctor with the medical board.

When the board investigator interviewed the doctor, the physician said he wasn’t aware the patient had called. But his staff said otherwise. Because the doctor had not been truthful, the board sent him a letter of guidance and required him to attend a training program in ethics.

Miami attorney William J. Spratt Jr., who supplied this anecdote about a former client, said that most complaints are dismissed with no action taken, but some complaints don’t go away because doctors mishandle them.

The following are some common mistakes that physicians make when dealing with a board complaint.
 

1. Not responding to the complaint

The complaint you get from the board – which often comes with a subpoena and a response deadline – usually asks for medical records pertinent to the case.

You can’t disregard the board’s letter, said Doug Brocker, an attorney handling board actions in Raleigh, N.C. “It’s amazing to me that some people just ignore a board complaint. Sometimes it’s because the doctor is just burnt out, which may have gotten the doctor into trouble in the first place.”

If you do not respond to a subpoena, “the board can file a court order holding you in contempt and start taking action on your license,” said Jeff Segal, MD, a neurosurgeon and attorney in Greensboro, N.C. Dr. Segal is CEO of Medical Justice Services, which protects physicians’ reputations associated with malpractice suits and board actions. “Not responding is not much different from agreeing to all of the charges.”
 

2. Not recognizing the seriousness of the complaint

“The biggest mistake is not taking a complaint seriously,” said Linda Stimmel, an attorney at Wilson Elser in Dallas. “Physicians who get a complaint often fire off a brief response stating that the complaint has no merit, without offering any evidence.”

According to Ms. Stimmel, “it’s really important to back up your assertions, such as using excerpts from the medical record, citations of peer-reviewed articles, or a letter of support from a colleague.”

“Weigh your answers carefully, because lack of accuracy will complicate your case,” Mr. Brocker said. “Consult the medical record rather than rely on your memory.”

“Present your version of events, in your own words, because that’s almost always better than the board’s version,” said Dr. Segal.

Even if there was a bad clinical outcome, Dr. Segal said you might point out that the patient was at high risk, or you could show that your clinical outcomes are better than the national average.
 

3. Thinking the board is on your side

You may be lulled into a false sense of security because the physicians on the medical board are your peers, but they can be as tough as any medical malpractice judge, said William P. Sullivan, DO, an emergency physician and attorney in Frankfort, Ill.

As per the National Practitioner Data Bank, physicians are three to four times more likely to incur an adverse board action than make a malpractice payout, Dr. Sullivan said.

Also, although a malpractice lawsuit rarely involves more than a monetary payment, a board action, like a monitoring plan, can restrict your ability to practice medicine. In fact, any kind of board action against you can make it harder to find employment.
 

4. Not being honest or forthcoming

“Lying to the board is the fastest way to turn what would have been a minor infraction into putting your license at risk,” Mr. Brocker said. This can happen when doctors update a medical record to support their version of events.

As per Dr. Sullivan, another way to put your license at risk is to withhold adverse information, which the board can detect by obtaining your application for hospital privileges or for licensure to another state, in which you revealed the adverse information.

Dr. Sullivan also advised against claiming you “always” take a certain precautionary measure. “In reality, we doctors don’t always do what we would like to have done. By saying you always do it when you didn’t, you appear less than truthful to the board, and boards have a hard time with that.”

Similarly, “when doctors don’t want to recognize that they could have handled things better, they tend to dance around the issue,” Mr. Brocker said. “This does not sit well with the board.” Insisting that you did everything right when it’s obvious that you didn’t can lead to harsher sanctions. “The board wants to make sure doctors recognize their mistakes and are willing to learn from them.”
 

5. Providing too much information

You may think that providing a great deal of information strengthens your case, but it can actually weaken it, Mr. Brocker said. Irrelevant information makes your response hard to follow, and it may contain evidence that could prompt another line of inquiry.

“Less is more,” Dr. Segal advised. “Present a coherent argument and keep to the most salient points.” Being concise is also good advice if your complaint proceeds to the board and you have to present your case.

Dr. Segal said the board will stop paying attention to long-winded presentations. He tells his clients to imagine the board is watching a movie. “If your presentation is tedious or hard to follow, you will lose them.”
 

6. Trying to contact the complainant

Complaints are kept anonymous, but in many cases, the doctor has an idea who the complainant was and may try to contact that person. “It’s natural to wonder why a patient would file a complaint against you,” Mr. Brocker said, but if you reach out to the patient to ask why, “it could look like you’re trying to persuade the patient to drop the complaint.”

Doctors who are involved in a practice breakup or a divorce can be victims of false and malicious complaints, but Beth Y. Collis, a partner at the law firm of Dinsmore & Shohl in Columbus, said boards are onto this tactic and usually reject these complaints.

The doctor may be tempted to sue the complainant, but Mr. Brocker said this won’t stop the complaint and could strengthen it. “Most statements to the medical board are protected from defamation lawsuits, and any lawsuit could appear to be intimidation.”
 

 

 

7. Simply signing a consent agreement

A small minority of complaints may result in the board taking action against the doctor. Typically, this involves getting the doctor to sign a consent agreement stating that he or she agrees with the board’s decision and its remedy, such as continuing education, a fine, or being placed under another doctor’s supervision.

“When the board sends you a consent agreement, it’s usually about something fairly minor,” Ms. Collis said. “You can make a counteroffer and see if they accept that. But once you enter into the agreement, you waive any right to appeal the board’s decision.”
 

8. Not hiring an attorney

Although some doctors manage to deal with a board complaint on their own, many will need to get an attorney, Mr. Brocker said. “An experienced attorney can help you navigate the board’s process.”

Clients often look for attorneys at the end of the process, when formal charges have already been filed, Mr. Brocker said. At that point, “it’s harder to get things moving in the right direction. You can’t unring the bell.”

Even if you don’t think you need an attorney throughout the case, “it helps to get advice from an attorney at the beginning,” Dr. Segal said. Doctors may think they can’t afford an attorney, but many malpractice carriers pay attorneys’ fees in medical board investigations.

Mr. Brocker advised finding an attorney who is familiar with licensing boards. “Malpractice attorneys may think they can deal with medical boards, but boards are quite different.” For example, “malpractice cases involve an adversarial approach, but licensing boards normally require working collaboratively.”
 

9. Not requesting a hearing

When the board takes action against you, it can be tempting to just accept the allegations and move on with your life, but it may be possible to undo the action, Dr. Sullivan said. “The board still has to prove its allegations, and it may not have a strong case against you.”

In some states, the medical board has to meet a very high standard of proof, Dr. Sullivan said. In Illinois, for example, the board must show “clear and convincing evidence,” while a malpractice plaintiff must only prove that it’s “more likely than not” that a physician violated the standard of care.

A hearing can especially help doctors facing harsh sanctions for minor offenses. For example, in a case handled by the law firm of Ray & Bishop in Newport Beach, Calif., a doctor who was stopped by police while driving home after having wine at a family gathering was found to have a blood alcohol level of 0.11%. Noting that the physician was on call at the time, the Medical Board of California decided to give him 5 years of probation.

Ray & Bishop asked for a judicial hearing to contest the decision. At the hearing, the physician noted that other physicians were also available to take call that night, and an expert stated that the doctor was not an alcohol abuser. The judge ruled that the board’s action was unduly harsh, and the physician received a public reprimand with no further penalties.
 

 

 

10. Getting upset with board officials

A board investigator may show up at your office uninvited and ask you to answer some questions, but you aren’t required to answer then and there, said Ms. Collis.

In fact, she noted, it’s never a good idea to let investigators into your office. “They can walk around, look through your records, and find more things to investigate.” For this reason, Ms. Collis makes it a point to schedule meetings with investigators at her office.

When you have to interact with board officials, such as during hearings, expressing anger is a mistake. “Some board members may raise their voices and make untrue assertions about your medical care,” Dr. Sullivan said. “You may wish you could respond in kind, but that will not help you.” Instead, calmly provide studies or guidelines supporting the care you provided.

Taking board investigators to task is also a mistake, Mr. Brocker pointed out. In his words, “investigators have to follow the rules. Getting mad at them will only make your case more difficult. Even if you believe the complaint against you is totally without merit, the process needs to run its course.”

Complaints are kept anonymous, but in many cases, the doctor has an idea who the complainant was and may try to contact that person. “It’s natural to wonder why a patient would file a complaint against you,” Mr. Brocker said, but if you reach out to the patient to ask why, “it could look like you’re trying to persuade the patient to drop the complaint.”

Doctors who are involved in a practice breakup or a divorce can be victims of false and malicious complaints, but Beth Y. Collis, a partner at the law firm of Dinsmore & Shohl in Columbus, said boards are onto this tactic and usually reject these complaints.

The doctor may be tempted to sue the complainant, but Mr. Brocker said this won’t stop the complaint and could strengthen it. “Most statements to the medical board are protected from defamation lawsuits, and any lawsuit could appear to be intimidation.”
 

 

 

7. Simply signing a consent agreement

A small minority of complaints may result in the board taking action against the doctor. Typically, this involves getting the doctor to sign a consent agreement stating that he or she agrees with the board’s decision and its remedy, such as continuing education, a fine, or being placed under another doctor’s supervision.

“When the board sends you a consent agreement, it’s usually about something fairly minor,” Ms. Collis said. “You can make a counteroffer and see if they accept that. But once you enter into the agreement, you waive any right to appeal the board’s decision.”
 

8. Not hiring an attorney

Although some doctors manage to deal with a board complaint on their own, many will need to get an attorney, Mr. Brocker said. “An experienced attorney can help you navigate the board’s process.”

Clients often look for attorneys at the end of the process, when formal charges have already been filed, Mr. Brocker said. At that point, “it’s harder to get things moving in the right direction. You can’t unring the bell.”

Even if you don’t think you need an attorney throughout the case, “it helps to get advice from an attorney at the beginning,” Dr. Segal said. Doctors may think they can’t afford an attorney, but many malpractice carriers pay attorneys’ fees in medical board investigations.

Mr. Brocker advised finding an attorney who is familiar with licensing boards. “Malpractice attorneys may think they can deal with medical boards, but boards are quite different.” For example, “malpractice cases involve an adversarial approach, but licensing boards normally require working collaboratively.”
 

9. Not requesting a hearing

When the board takes action against you, it can be tempting to just accept the allegations and move on with your life, but it may be possible to undo the action, Dr. Sullivan said. “The board still has to prove its allegations, and it may not have a strong case against you.”

In some states, the medical board has to meet a very high standard of proof, Dr. Sullivan said. In Illinois, for example, the board must show “clear and convincing evidence,” while a malpractice plaintiff must only prove that it’s “more likely than not” that a physician violated the standard of care.

A hearing can especially help doctors facing harsh sanctions for minor offenses. For example, in a case handled by the law firm of Ray & Bishop in Newport Beach, Calif., a doctor who was stopped by police while driving home after having wine at a family gathering was found to have a blood alcohol level of 0.11%. Noting that the physician was on call at the time, the Medical Board of California decided to give him 5 years of probation.

Ray & Bishop asked for a judicial hearing to contest the decision. At the hearing, the physician noted that other physicians were also available to take call that night, and an expert stated that the doctor was not an alcohol abuser. The judge ruled that the board’s action was unduly harsh, and the physician received a public reprimand with no further penalties.
 

 

 

10. Getting upset with board officials

A board investigator may show up at your office uninvited and ask you to answer some questions, but you aren’t required to answer then and there, said Ms. Collis.

In fact, she noted, it’s never a good idea to let investigators into your office. “They can walk around, look through your records, and find more things to investigate.” For this reason, Ms. Collis makes it a point to schedule meetings with investigators at her office.

When you have to interact with board officials, such as during hearings, expressing anger is a mistake. “Some board members may raise their voices and make untrue assertions about your medical care,” Dr. Sullivan said. “You may wish you could respond in kind, but that will not help you.” Instead, calmly provide studies or guidelines supporting the care you provided.

Taking board investigators to task is also a mistake, Mr. Brocker pointed out. In his words, “investigators have to follow the rules. Getting mad at them will only make your case more difficult. Even if you believe the complaint against you is totally without merit, the process needs to run its course.”

Men with hypersexual disorder may have oxytocin overload

Article Type
Changed

Men with hypersexual disorder showed higher levels of oxytocin in their blood than did healthy control men without the disorder, in a study with 102 participants.

Hypersexual disorder (HD) is characterized by “excessive and persistent sexual behaviors in relation to various mood states, with an impulsivity component and experienced loss of control,” John Flanagan, MD, of the Karolinska Institutet in Stockholm and colleagues wrote. Although HD is not included as a separate diagnosis in the current DSM, the similar disorder of compulsive sexual behavior is included in the ICD.

Data on the pathophysiology of HD are limited, although a previous study by corresponding author Andreas Chatzittofis, MD, and colleagues showed evidence of neuroendocrine dysregulation in men with HD, and prompted the current study to explore the possible involvement of the oxytocinergic system in HD.

In the current study, published in the Journal of Clinical Endocrinology & Metabolism, the researchers identified 64 men with HD and 38 healthy male controls. The patients were help-seeking men older than 18 years diagnosed with HD who presented to a single center in Sweden during 2013-2014. The men were included in a randomized clinical trial of cognitive-behavioral therapy for HD, and 30 of them participated in a 7-week CBT program.

Oxytocin, secreted by the pituitary gland, is known to play a role in sexual behavior, but has not been examined in HD men, the researchers said. At baseline, the mean plasma oxytocin was 31.0 pM in the HD patients, which was significantly higher than the mean 16.9 pM in healthy controls (P < .001). However, the 30 HD men who underwent CBT showed significant improvement in oxytocin levels, from a mean pretreatment level of 30.5 to a mean posttreatment level of 20.2 pM (P = .0000019).

The study findings were limited by several factors, including the lack of data on oxytocin for a wait list or control group, as well as the inability to control for confounding factors such as diet, physical activity, ethnicity, and stress, and a lack of data on sexual activity prior to oxytocin measurements, the researchers noted.

However, “although there is no clear consensus at this point, previous studies support the use of oxytocin plasma levels as a surrogate variable for [cerebrospinal fluid] oxytocin activity,” the researchers wrote in their discussion. The current study findings support the potential of oxytocin as a biomarker for HD diagnostics and also as a measure of disease severity. Larger studies to confirm the findings, especially those that exclude potential confounders, would be valuable.

Oxytocin may be treatment target

The study is important because of the lack of knowledge regarding the pathophysiology underlying hypersexual disorder, Dr. Chatzittofis of the University of Cyprus, Nicosia, said in an interview. “This is the first study to indicate a role for oxytocin’s involvement” in hypersexual disorder in men. Dr. Chatzittofis led a team in a previous study that showed an association between HD in men and dysregulation of the hypothalamic pituitary adrenal axis.

Dr. Andreas Chatzittofis

In the current study, “we discovered that men with compulsive sexual behavior disorder had higher oxytocin levels, compared with healthy men,” said Dr. Chatzittofis, adding that the take-home message for clinicians is the potential of CBT for treatment. “Cognitive-behavior therapy led to a reduction in both hypersexual behavior and oxytocin levels.” The results suggest that oxytocin plays an important role in sex addiction.

Consequently, oxytocin may be a potential drug target for future pharmacologic treatment of hypersexual disorder, he added.

The study was supported by the Swedish Research Council, the Stockholm County Council, and by a partnership between Umeå University and Västerbotten County Council. The researchers had no financial conflicts to disclose.

OTC melatonin supplement use rises fivefold over 20 years

Article Type
Changed

The use of over-the-counter melatonin supplements grew by fivefold over the past 2 decades in the United States, a new study finds, although only 2% of a recent group of survey respondents said they had taken the sleep aid within the past month.

The findings, reported Feb. 1 in a research letter in the Journal of the American Medical Association, suggest that “millions of U.S. individuals are using melatonin,” study coauthor Naima Covassin, PhD, an associate consultant at Mayo Clinic in Rochester, Minn., told this news organization. “It is important to ask patients who report sleep problems whether they consume melatonin supplements, and these findings should certainly prompt more research in this area.”

The supplements boost the levels of melatonin, a hormone that is linked to the sleep-wake cycle. “Melatonin facilitates our ability to fall asleep at our bedtime by decreasing the natural early evening circadian arousal that helps keep us alert despite our having been awake since the morning,” said David N. Neubauer, MD, a sleep specialist at Johns Hopkins University, Baltimore. “It isn’t so much that melatonin is sedating, but rather that it turns off arousal.”

Dr. David N. Neubauer

For the new study, researchers tracked data from the National Health and Nutrition Examination Survey from 1999-2000 to 2017-2018 and focused on respondents aged 20 and older (n = 55,021, mean age, 47.5, 52% women). As the researchers noted, response rates dipped mightily from a high of 84% in 2001-2002 to just 51.9% in 2017-2018.

The study found that the overall reported weighted prevalence of melatonin use grew from 0.4% (95% confidence interval, 0.2%-1.0%) in 1999-2000 to 2.1% (95% CI, 1.5%-2.9%) in 2017-2018 (linear P = .004). In 93.9% of cases of reported melatonin use, the surveyors confirmed it by checking for supplement bottles.

“These trends were similar in men and women and across age groups,” Dr. Covassin said. “We also found that use of more than 5 mg/day melatonin was not reported till 2005-2006, and it has been increasing since.”

Melatonin supplements are now available in tablets, capsules, gummies, powders, liquids, sprays, and other formulations. Users can even buy CBD-melatonin combos.

The survey doesn’t explore why the respondents used melatonin nor whether they thought it actually helped them. “The study was designed to evaluate the breadth of use of melatonin, rather than its effectiveness as a sleep aid,” Dr. Covassin said.

Dr. Neubauer, who wasn’t associated with the study, said the research seems valid. According to him, melatonin use has likely grown because of marketing and a higher number of products. He added that melatonin products are being manufactured at higher doses, although melatonin has a flat dose-response curve. “Higher doses typically do not have a greater effect,” he said.

According to Dr. Covassin, melatonin is generally considered to be safe, although side effects such as fatigue, dizziness, and headaches have been reported in clinical trials. “This is especially evident when high doses are administered,” Dr. Covassin said. “Other potentially more harmful consequences have also been noted. For instance, it has been found that acute administration of melatonin may decrease glucose tolerance, which may be especially problematic in patients with preexisting vulnerabilities such in those with diabetes. There are also very limited data on whether sustained use is safe in the long run.”

Moving forward, Dr. Covassin said, “we are interested in better understanding consumption of melatonin supplements across different populations as well as the impact of chronic use.”

The study authors are supported by grants from the National Natural Science Foundation of China, National Institutes of Health, Sleep Number Corporation (to Mayo Clinic), the Alice Sheets Marriott Professorship, and the Mayo Clinic Marie Ingalls Research Career Development Award.

Dr. Covassin and Dr. Neubauer have disclosed no relevant financial relationships. Study coauthor Virend K. Somers, MD, PhD, reports having served as a consultant for Respicardia, Baker Tilly, Bayer, and Jazz Pharmaceuticals and serving on the Sleep Number Research Advisory Board.
