Retro-orbital headache and nausea
On the basis of his presentation, this patient is probably experiencing migraine with visual aura. Migraine is a condition in children and adolescents whose prevalence increases with age: 1%-3% between age 3 and 7 years, 4%-11% between age 7 and 11 years, and 8%-23% by age 15 years. Although migraine without aura is relatively uncommon in the pediatric population, visual aura is a hallmark sign of migraine headache and excludes the other headache types in the differential diagnosis. Basilar migraine is unlikely because the patient has not experienced symptoms that suggest occipital or brainstem area dysfunction post-aura.
The diagnosis of migraine is largely clinical, but the American Academy of Neurology (AAN) guidelines for the acute treatment of pediatric migraine recommend that when assessing children and adolescents with headache, clinicians should diagnose a specific headache type: primary, secondary, or other headache syndrome. Migraine in pediatric patients is often related to triggering factors such as infection, physical or psychological stress, or dietary choices, but on the basis of the patient's history, this headache appears to be primary in nature.
Most pediatric patients can achieve control of their migraines with acute treatments and benefit from nonprescription oral analgesics, including acetaminophen, ibuprofen, and naproxen. Clinicians should prescribe ibuprofen orally (10 mg/kg) as an initial treatment for children and adolescents with migraine. The US Food and Drug Administration has only approved certain triptans for pediatric patients: almotriptan, sumatriptan-naproxen, and zolmitriptan nasal spray for patients aged 12 years or older and rizatriptan for patients aged 6-17 years.
The AAN guidelines for the pharmacologic treatment of pediatric migraine prevention report that for those who experience migraine with aura, taking a triptan during the aura is safe, though it may be more effective when taken at the onset of head pain, as is the case with other acute treatments.
In pediatric patients, avoidance of known headache triggers is generally sufficient for migraine prevention. This includes managing anxiety, depression, attention-deficit/hyperactivity disorder, and other psychiatric comorbidities that can exacerbate headache. Lifestyle management also includes ensuring adequate sleep, exercise, hydration, and stress management.
The guidelines conclude that although the majority of randomized controlled trials exploring the efficacy of preventive medications in the pediatric population fail to demonstrate superiority to placebo, migraine prophylaxis should be considered when headaches occur with high frequency and severity and cause migraine-related disability based on the Pediatric Migraine Disability Assessment (PedMIDAS).

The patient's mother reports that he described seeing "rainbow shapes" in his line of vision about 20 minutes before the onset of head pain and notes that she herself has a history of headache. The patient is nonfebrile but sweating and drowsy. Physical examination is unrevealing. The patient has no known allergies and is not currently on medication.
RaDonda Vaught: Victim, felon, or both?
For 4 and a half years, I have followed the RaDonda Vaught medication error that led to the unfortunate death of a human being. I am not alone. Nurses across the country have followed the case with anxiety and fear, knowing a guilty verdict might have the potential to challenge basic tenets of care.
According to Kaiser Health News, nurses are “raging and quitting” following the announcement of a guilty verdict for two felonies: criminally negligent homicide and gross neglect of an impaired adult.
Thousands of nurses have claimed they could arrive in Nashville, Tenn., on May 13, the day Ms. Vaught is to be sentenced, to protest the conviction. Others have stated they believe justice is being conducted, as their sympathies lie with the victim, Charlene Murphey, who died 12 hours after being unable to draw breath, paralyzed from the inadvertent dose of vecuronium given intravenously by her nurse.
How should we feel as clinicians? according to sentencing guidelines?
My belief is that it is understandable to feel passionately about this case, including what it could mean to an era of “just culture” that nursing organizations have promoted. The concept of just culture looks at medication/nursing errors as opportunities for growth to avoid future errors, not as scenarios for punitive action. With the guilty verdict in Ms. Vaught’s case, nurses (and facilities) fear that nurses will avoid coming forward after mistakes, leading to cover-ups and a culture perspective.
Will nurses be hesitant to report errors (especially significant errors) that lead to patient harm? Will we fear retribution and reprisal for being truthful?
I believe that Ms. Vaught’s criminal case has changed little in the political landscape of caregiving. Before you let loose with a loud expletive (or two), hear me out.
When a patient dies from unintentional harm, someone must be held accountable. Society needs a scapegoat, and unfortunately, excrement slides downhill to the lowest common denominator, which may be the nurse. Initially, Ms. Vaught was contacted by her state licensing board (Tennessee) and informed there would be no professional repercussions for her mistake. That decision did not hold. She was later indicted criminally for the death of her patient. She also had her nursing license revoked.
Why? The hospital where she worked was threatened with Medicare reprisal if systemic issues were not addressed following the incident; for example, a bar-coding device was not available for Ms. Vaught to use prior to administering the vecuronium, and paralytic agents were stored unsafely in a Pyxis MedStation, readily available for any nurse to obtain via override.
In fact, the number of overrides performed by all nurses caring for Ms. Murphey in the days leading to her death was alarming, leading reviewers to assume that time to acquire medication for inpatients was a problem.
Ms. Vaught herself, stating the obvious on talk shows, said she should not have performed an override, that the situation was “not an emergency” and she should have taken time to check that Versed (midazolam) was available by the generic name and not the “VE” she entered as a search mechanism into the machine. She also stated she was “distracted” by a trainee assigned to her at the time.
We have all been there, feeling rushed to perform a task under stressful situations, skipping safety guidelines to sedate a patient while radiology is waiting. Someone is always on our a**, waiting to get to the next task, the next patient, the next admission, the next pseudo-emergency called nursing workload.
It never ends.
Which is why I wish to emphasize what the Ms. Vaught guilty verdict really means for nurses.
It means we must never forget that our actions have the potential to harm, even kill, our patients.
We must never forget that repercussions and reprisal may occur, whether personal guilt that may prove more damaging than the prison sentence Ms. Vaught might receive, or problems that could result if nurses attempt to hide or subvert medication issues.
In Ms. Vaught’s case, she did not document the medication that had been given to Ms. Murphey, facts the prosecution seized on to proclaim her guilt. Why? We can only guess at this point. But her claims of truthfulness need to be balanced by what occurred, and the facts are that she did not document the error after administering vecuronium that night.
When reflecting on this verdict, we need to remember a patient died, and she did so horribly, being unable to draw breath. This should never happen during our watch, ever, and as clinicians, we need to be vigilant.
In summary, protest if you believe justice has been too harsh or unfair, and that nurses may be fearful as a result. But please spare a moment to realize that someone should protest for Ms. Murphey as well. We cannot bring her back, nor can we right the system issues that may have led to her death.
But we should protest for safer systems, for improved staffing, for a need to catch our collective breaths, and a day to work and nurture patients when someone is not constantly on our a**. Only then will nurses be protected from unjust reprisal, from needing to be the lowest common denominator of guilt.

Biomarker testing gains momentum in NSCLC
Despite Spain’s lack of a national project or standard protocol for biomarker testing, reported at the 2022 European Lung Cancer Congress.
“In recent years we’ve developed drugs that target biomarkers, so it’s important to identify those biomarkers to guide treatment and have an impact on the survival of our patients,” said lead author Virginia Calvo, MD, a medical oncologist with the Puerta de Hierro Majadahonda University Hospital, Madrid.
“If we don’t know our patients’ biomarkers, we can’t treat them with targeted therapies,” she added, noting that the overall survival of lung cancer patients has increased by 15% in the last 10 years, largely because of better therapies such as targeted drugs for advanced stage disease and immunotherapies.
To assess the status of biomarker testing in Spain, Dr. Calvo and colleagues analyzed data from the country’s Thoracic Tumor Registry on 9,239 patients diagnosed with metastatic NSCLC from 2016 to the present, 7,467 (81%) with nonsquamous tumors and 1,772 (19%) with squamous tumors.
They found that 85% of patients with nonsquamous NSCLC and about 53% of those with squamous cancers had undergone biomarker testing. They discovered that 4,115 (44%) of patients tested positive for EGFR, ALK, KRAS, BRAF, ROS1, or PD-L1.
Dr. Calvo attributes the widespread use of biomarker testing and its significant increase in the last 5 years to the growing knowledge and understanding of the disease.
“We are learning more about NSCLC, and I think in the next few years the number of biomarkers are going to grow,” she said.
The study’s findings also highlight the importance of establishing and maintaining cancer registries, Dr. Calvo said, noting that 182 hospitals across Spain and more than 550 experts participate in the Thoracic Tumors Registry, which includes data on patients from every Spanish territory.
“It’s important to collect information on real-life cancer care so that we know what our real situation is and take steps to improve it,” she said.
She anticipates that treatment for NSCLC patients will become increasingly complex in the future with the growing number of different biomarkers and the proportion of patients who test positive for them. “We may need to establish national strategies to implement next generation sequencing so that we can identify different biomarkers and improve the survival of our patients.”
In a press release, Rolf Stahel, MD, president of the European Thoracic Oncology Platform, said that it would be helpful to look at how frequently molecular testing led to patients receiving appropriate targeted treatment.
In the United States, the National Comprehensive Cancer Network recommends biomarker testing for eligible patients with newly diagnosed stage 4 NSCLC, and it can be considered for patients with squamous histology because 5%-10% of these tumors have targetable mutations. “This is because numerous lines of evidence show that patients with stage 4 NSCLC and a targetable mutation, typically have improved overall survival when treated with a targeted therapy,” wrote the authors of the NCCN recommendations.
“For newly diagnosed stage 4 NSCLC, there is always a tension between the need to start therapy versus waiting for molecular results. This is because if a recommended targeted option is identified, it is the optimal first-line therapy. Targeted therapy cannot be given to everyone. Different biomarkers predict response to different agents. This has been well illustrated and it makes testing critically important for patients with NSCLC,” Dara Aisner, MD, PhD, associate professor of pathology with the University of Colorado at Denver, Aurora, wrote in the NCCN guideline.
The study presented at ELCC was funded by a grant from the European Union’s Horizon 2020 Research and Innovation Program. Dr. Calvo has received fees from Roche, Bristol-Myers Squibb, MSD and AstraZeneca.

Young and older athletes show similar arrhythmia patterns with fQRS
The prevalence of exercise-induced arrhythmias in young athletes with fragmented QRS (fQRS) patterns in lead V1 was 27%, similar to that seen in adult athletes, based on data from nearly 700 individuals.
Recent data suggest that fQRS complex in lead V1 (fQRSV1) in healthy athletes may promote arrhythmias in the context of training-induced right ventricular remodeling, but the prevalence and significance in young athletes has not been well studied, Guilia Quinto, MD, of the University of Padova (Italy) said in a presentation at the annual congress of the European Association of Preventive Cardiology.
Dr. Quinto and colleagues assessed data from of young athletes on ventricular arrhythmias during exercise tests.
The study population included 684 young athletes with a mean age of 15 years; 64% were male. Baseline data collection included medical history, physical exam, resting ECG, standardized maximum exercise tolerance, and echocardiography evaluation.
The overall prevalence of fQRSV1 was 27%. Individuals with fQRSV1 were significantly less likely than those without fQRSV1 to be female (22% vs. 43%), and to present with a lower resting heart rate (66.98 beats per minute vs. 70.08 beats per minute).
Echocardiographic data showed that individuals with fQRSV1 had significantly different morphological and functional right ventricular characteristics.
Notably, right ventricular end-diastolic diameter was 20.42 mm/m2 among individuals with fQRSV1 and 19.81 mm/m2 in those without, a significant difference (P = .019), Dr. Quinto said. Tricuspid annulus plain systolic excursion also differed significantly; 24.33 mm and 23.75 mm for individuals with and without fQRSV1, respectively (P = .013).
However, the individuals with fQRSV1 showed no increased occurrence of any type of exercise-induced arrhythmias regardless of morphology or complexity, said Dr. Quinto.
The prevalence of common and uncommon arrhythmias among individuals with and without fQRSV1 was 31% versus 34% and 13% versus 11%, respectively; these differences were not significant.
The study findings were limited by the relatively small size, but were strengthened by the review of echocardiographic data by two independent physicians, she said.
The results show that the overall prevalence of fQRSV1 in young athletes is comparable with patterns seen in studies of adult athletes, and no differences in exercise-induced arrhythmias occurred despite differences in right ventricular characteristics, she concluded.
Expanded insight into evaluation
The ECG pattern identified in the current study is often encountered in the evaluation of athletes, but its importance was unknown, Matthew Martinez, MD, a sports cardiologist at the Atlantic Health System in Morristown, N.J., said in an interview.
“Studies of ECG findings in athletes continues to inform us about which findings are important to evaluate. This study furthers our understanding of how to proceed,” and will serve as a guide for additional testing to reduce athlete risk, he said.
Looking ahead, “this study should guide clinicians about additional testing and evaluation when fQRS is present in adolescent athletes compared to adults,” Dr. Martinez noted. However, additional research is needed to determine which is the next best test, and whether the patient requires ongoing surveillance, or whether a single evaluation is sufficient, he said. “Further study should focus on best practices after fQRS is identified and whether outcomes can be linked to this finding.”
The study received no outside funding. Dr. Quinto and Dr. Martinez had no financial conflicts to disclose.

Excess weight over lifetime hikes risk for colorectal cancer
Excess weight over a lifetime may play a greater role in a person’s risk for colorectal cancer (CRC) than previously thought, according to new research.
In their paper published online March 17 in JAMA Oncology, the authors liken the cumulative effects of a lifetime with overweight or obesity to the increased risk of cancer the more people smoke over time.
This population-based, case-control study was led by Xiangwei Li, MSc, of the division of clinical epidemiology and aging research at the German Cancer Research Center in Heidelberg.
It looked at height and self-reported weight documented in 10-year increments starting at age 20 years up to the current age for 5,635 people with CRC compared with 4,515 people in a control group.
Odds for colorectal cancer increased substantially over the decades when people carried the excess weight long term compared with participants who remained within the normal weight range during the period.
Coauthor Hermann Brenner, MD, MPH, a colleague in Li’s division at the German Cancer Research Center, said in an interview that a key message in the research is that “overweight and obesity are likely to increase the risk of colorectal cancer more strongly than suggested by previous studies that typically had considered body weight only at a single point of time.”
The researchers used a measure of weighted number of years lived with overweight or obesity (WYOs) determined by multiplying excess body mass index by number of years the person carried the excess weight.
They found a link between WYOs and CRC risk, with adjusted odds ratios (ORs) increasing from 1.25 (95% confidence interval [CI], 1.09-1.44) to 2.54 (95% CI, 2.24-2.89) from the first to the fourth quartile of WYOs, compared with people who stayed within normal weight parameters.
The odds went up substantially the longer the time carrying the excess weight.
“Each SD increment in WYOs was associated with an increase of CRC risk by 55% (adjusted OR, 1.55; 95% CI, 1.46-1.64),” the authors wrote. “This OR was higher than the OR per SD increase of excess body mass index at any single point of time, which ranged from 1.04 (95% CI, 0.93-1.16) to 1.27 (95% CI 1.16-1.39).”
Dr. Brenner said that although this study focused on colorectal cancer, “the same is likely to apply for other cancers and other chronic diseases.”
Prevention of overweight and obesity to reduce burden of cancer and other chronic diseases “should become a public health priority,” he said.
Preventing overweight in childhood is important
Overweight and obesity increasingly are starting in childhood, he noted, and may be a lifelong burden.
Therefore, “efforts to prevent their development in childhood, adolescence, and young adulthood are particularly important,” Dr. Brenner said.
The average age of the patients was 68 years in both the CRC and control groups. There were more men than women in both groups: 59.7% were men in the CRC group and 61.1% were men in the control group.
“Our proposed concept of WYOs is comparable to the concept of pack-years in that WYOs can be considered a weighted measure of years lived with the exposure, with weights reflecting the intensity of exposure,” the authors wrote.
Study helps confirm what is becoming more clear to researchers
Kimmie Ng, MD, MPH, a professor at Harvard Medical School and oncologist at Dana-Farber Cancer Institute, both in Boston, said in an interview that the study helps confirm what is becoming more clear to researchers.
“We do think that exposures over the life course are the ones that will be most strongly contributing to a risk of colorectal cancer as an adult,” she said. “With obesity, what we think is happening is that it’s setting up this milieu of chronic inflammation and insulin resistance and we know those two factors can lead to higher rates of colorectal cancer development and increased tumor growth.”
She said the ideal, but impractical, way to do the study would be to follow healthy people from childhood and document their weight over a lifetime. In this case-control study, people were asked to recall their weight at different time periods, which is a limitation and could lead to recall bias.
But the study is important, Dr. Ng said, and it adds convincing evidence that addressing the link between excess weight and CRC and chronic diseases should be a public health priority. “With the recent rise in young-onset colorectal cancer since the 1990s there has been a lot of interest in looking at whether obesity is a major contributor to that rising trend,” Dr. Ng noted. “If obesity is truly linked to colorectal cancer, these rising rates of obesity are very worrisome for potentially leading to more colorectal cancers in young adulthood and beyond.“
The study authors and Dr. Ng report no relevant financial relationships.

Diet’s impact on the microbiome: It’s real, and broad
WASHINGTON – – including amino acid metabolites – that may modify health, said Gary D. Wu, MD, of the University of Pennsylvania, Philadelphia.
During the 2022 Gut Microbiota for Health World Summit, organized by the American Gastroenterological Association and the European Society of Neurogastroenterology and Motility, Dr. Wu led a plenary session in which the impact of diet on the microbiome was characterized as important, rapid, personalized, likely modest relative to other contributing ecological factors, influenced by the process of cooking, and exceedingly difficult to tease apart and characterize in human studies.
In a human study published in 2021, Dr. Wu and coinvestigators performed a controlled feeding experiment with 30 healthy volunteers, randomizing them to several weeks of a vegan diet, an omnivore diet (a typical American diet), and an exclusive enteral nutrition diet (EEN) devoid of dietary fiber.
They compared the composition and metabolic function of the gut microbiome during three phases: an initial dietary phase (days 1-5), a purge phase in which antibiotics and polyethylene glycol were administered to transiently reduce bacterial load in the gut (days 6-8), and a recovery phase (days 9-15).
Diversity of the gut microbiota recovered from the purge phase in both vegans and omnivores, but not in those receiving EEN. “The EEN diet was having a profound effect on the [short-term] recovery of microbiota,” said Dr. Wu, the Ferdinand G. Weisbrod Professor in Gastroenterology, in describing the Food And Resulting Microbial Metabolites study.
Using genetic sequencing, microbial culturing, and bioinformatics processing, the researchers also determined that EEN subsequently led to metabolites that were distinct from omnivores and vegans. Unexpectedly, bacterial metabolites of amino acid origin – not only carbohydrate origin – were altered in the EEN group, suggesting a broad impact of dietary fiber on the bacterial metabolome. EEN-induced alterations in the microbiome and metabolome resolved after the study period, he noted.
In other words, “depriving or supplying the gut microbiome with one dietary component (i.e., fiber) can directly impact metabolites of an unrelated portion of the diet (i.e., amino acids) via the induction of specific gut bacterial taxa,” Dr. Wu and colleagues wrote.
Clinically, the results as a whole suggest that the combination of antibiotics with EEN may be less effective in patients with Crohn’s disease than EEN alone, and can be potentially harmful, they said.
At the meeting, sponsored by the American Gastroenterological Association and the European Society for Neurogastroenterology and Motility, Dr. Wu said that, for patients in the ICU on EEN treatment and antibiotics, “we do need to think carefully about microbiota reconstitution because it could have a very significant effect not only on short-chain fatty acid metabolites but on amino acid metabolites that may be good or bad in the setting of disease.”
The scientific rationale for the effectiveness of EEN for IBD is still not well understood, he noted. “All I can say is that EEN works in IBD, but there are aspects about the microbiota and diet and IBD that we don’t understand.”
Dietary impact through the immigration lens
In another presentation, Dan Knights, PhD, of the University of Minnesota, Minneapolis, described his lab’s findings on the association of U.S. immigration with loss of gut microbiome diversity, and the role of diet.
As part of the Immigration Microbiome Project reported several years ago, his team collected stool, dietary recalls, and anthropometrics from 550 Hmong and Karen individuals living in Thailand and the United States, including first- and second-generation immigrants, as well as some U.S.-born European American individuals. They found that the gut microbiome of immigrants changed within months of arriving in the United States, and that immigration status had a stronger effect on the microbiome than obesity status.
“By the time people were in their second generation, their microbiomes were roughly on the same order of diversity as U.S. controls,” said Dr. Knights, associate professor in the Biotechnology Institute and the department of computer science and engineering.
Dietary changes only partly explained microbiome variation, however. “By the second generation, the microbiome tended to be fully Westernized, but the diet was only partly Westernized,” he said. “Diet is only part of the story.”
Other research from his lab, including one study that performed daily fecal shotgun sequencing on 34 people, has found that effects of diet on the microbiome are likely to be observable within days, and that microbial responses to food are highly personalized. Diet appears to explain about 6% of the daily microbiome variation within an individual, and “an average diet explains about 4% of microbiome variation between people,” Dr. Knights said.
The impact of cooking
“The gut microbiota responds to food and to its form,” said Rachel N. Carmody, PhD, of the department of human evolutionary biology at Harvard University, Cambridge, during the plenary session. Her research has shown that, in mice, a plant diet served raw versus cooked quickly reshaped the gut microbiome and disrupted gut microbial physiology. Notably, shifts in gut microbiota modulated host energy status – one of the many areas that begs further research.
The effects of cooking have also been detectable in human pilot studies. “We saw different changes in the microbiome when [study participants] were eating the same plant items either raw or cooked,” she said. “Some microbes were affected only on the raw diet, other were affected only on the cooked diet.”
Other research in animal models and humans has demonstrated a significant amount of plasticity in the microbiome in response to diet. “In mice you get the microbiome signatures to shift within 24 hours by feeding them a new diet,” Dr. Carmody said.
In an interview about the plenary session, Eugene B. Chang, MD, the Martin Boyer Distinguished Professor of Medicine at the University of Chicago, said that he was struck both by the resiliency of individual gut microbiomes overall and by findings that, “in animal models where conditions and diets can be carefully controlled, diet and environment are major drivers of gut microbial membership and function.”
Dr. Chang coled a separate workshop on “defining a healthy gut microbiome” – a task that he said remains “a challenge [and is not yet] resolved, at least with general consensus.”
Dr. Chang, Dr. Wu, and Dr. Carmody reported no relevant disclosures. Dr. Knights disclosed that he is a paid adviser to Diversigen, a company involved with the commercialization of microbiome analysis.

In another presentation, Dan Knights, PhD, of the University of Minnesota, Minneapolis, described his lab’s findings on the association of U.S. immigration with loss of gut microbiome diversity, and the role of diet.
As part of the Immigration Microbiome Project reported several years ago, his team collected stool, dietary recalls, and anthropometrics from 550 Hmong and Karen individuals living in Thailand and the United States, including first- and second-generation immigrants, as well as some U.S.-born European American individuals. They found that the gut microbiome of immigrants changed within months of arriving in the United States, and that immigration status had a stronger effect on the microbiome than obesity status.
“By the time people were in their second generation, their microbiomes were roughly on the same order of diversity as U.S. controls,” said Dr. Knights, associate professor in the Biotechnology Institute and the department of computer science and engineering.
Dietary changes only partly explained microbiome variation, however. “By the second generation, the microbiome tended to be fully Westernized, but the diet was only partly Westernized,” he said. “Diet is only part of the story.”
Other research from his lab, including one study that performed daily fecal shotgun sequencing on 34 people, has found that effects of diet on the microbiome are likely to be observable within days, and that microbial responses to food are highly personalized. Diet appears to explain about 6% of the daily microbiome variation within an individual, and “an average diet explains about 4% of microbiome variation between people,” Dr. Knights said.
The impact of cooking
“The gut microbiota responds to food and to its form,” said Rachel N. Carmody, PhD, of the department of human evolutionary biology at Harvard University, Cambridge, during the plenary session. Her research has shown that, in mice, a plant diet served raw versus cooked quickly reshaped the gut microbiome and disrupted gut microbial physiology. Notably, shifts in gut microbiota modulated host energy status – one of the many areas that begs further research.
The effects of cooking have also been detectable in human pilot studies. “We saw different changes in the microbiome when [study participants] were eating the same plant items either raw or cooked,” she said. “Some microbes were affected only on the raw diet, other were affected only on the cooked diet.”
Other research in animal models and humans has demonstrated a significant amount of plasticity in the microbiome in response to diet. “In mice you get the microbiome signatures to shift within 24 hours by feeding them a new diet,” Dr. Carmody said.
In an interview about the plenary session, Eugene B. Chang, MD, the Martin Boyer Distinguished Professor of Medicine at the University of Chicago, said that he was struck both by the resiliency of individual gut microbiomes overall and by findings that, “in animal models where conditions and diets can be carefully controlled, diet and environment are major drivers of gut microbial membership and function.”
Dr. Chang coled a separate workshop on “defining a healthy gut microbiome” – a task that he said remains “a challenge [and is not yet] resolved, at least with general consensus.”
Dr. Chang, Dr. Wu, and Dr. Carmody reported no relevant disclosures. Dr. Knights disclosed that he is a paid adviser to Diversigen, a company involved with the commercialization of microbiome analysis.

WASHINGTON – – including amino acid metabolites – that may modify health, said Gary D. Wu, MD, of the University of Pennsylvania, Philadelphia.
During the 2022 Gut Microbiota for Health World Summit, organized by the American Gastroenterological Association and the European Society of Neurogastroenterology and Motility, Dr. Wu led a plenary session in which the impact of diet on the microbiome was characterized as important, rapid, personalized, likely modest relative to other contributing ecological factors, influenced by the process of cooking, and exceedingly difficult to tease apart and characterize in human studies.
In a human study published in 2021, Dr. Wu and coinvestigators performed a controlled feeding experiment with 30 healthy volunteers, randomizing them to several weeks of a vegan diet, an omnivore diet (a typical American diet), and an exclusive enteral nutrition diet (EEN) devoid of dietary fiber.
They compared the composition and metabolic function of the gut microbiome during three phases: an initial dietary phase (days 1-5), a purge phase in which antibiotics and polyethylene glycol were administered to transiently reduce bacterial load in the gut (days 6-8), and a recovery phase (days 9-15).
Diversity of the gut microbiota recovered from the purge phase in both vegans and omnivores, but not in those receiving EEN. “The EEN diet was having a profound effect on the [short-term] recovery of microbiota,” said Dr. Wu, the Ferdinand G. Weisbrod Professor in Gastroenterology, in describing the Food And Resulting Microbial Metabolites study.
Using genetic sequencing, microbial culturing, and bioinformatics processing, the researchers also determined that EEN subsequently led to metabolites that were distinct from omnivores and vegans. Unexpectedly, bacterial metabolites of amino acid origin – not only carbohydrate origin – were altered in the EEN group, suggesting a broad impact of dietary fiber on the bacterial metabolome. EEN-induced alterations in the microbiome and metabolome resolved after the study period, he noted.
In other words, “depriving or supplying the gut microbiome with one dietary component (i.e., fiber) can directly impact metabolites of an unrelated portion of the diet (i.e., amino acids) via the induction of specific gut bacterial taxa,” Dr. Wu and colleagues wrote.
Clinically, the results as a whole suggest that the combination of antibiotics with EEN may be less effective in patients with Crohn’s disease than EEN alone, and can be potentially harmful, they said.
At the meeting, sponsored by the American Gastroenterological Association and the European Society for Neurogastroenterology and Motility, Dr. Wu said that, for patients in the ICU on EEN treatment and antibiotics, “we do need to think carefully about microbiota reconstitution because it could have a very significant effect not only on short-chain fatty acid metabolites but on amino acid metabolites that may be good or bad in the setting of disease.”
The scientific rationale for the effectiveness of EEN for IBD is still not well understood, he noted. “All I can say is that EEN works in IBD, but there are aspects about the microbiota and diet and IBD that we don’t understand.”

30% of COVID patients in study developed long COVID
Journal of General Internal Medicine.
University of California, Los Angeles, researchers said in a study published in theThe UCLA researchers studied 1,038 people enrolled in the UCLA COVID Ambulatory Program between April 2020 and February 2021 and found that 309 developed long COVID.
A long-COVID diagnosis came if a patient answering a questionnaire reported persistent symptoms 60-90 days after they were infected or hospitalized. The most persistent symptoms were fatigue (31%) and shortness of breath (15%) in hospitalized participants. Among outpatients, 16% reported losing sense of smell.
The study’s findings differ from earlier research. The University of California, Davis, for example, estimated that 10% of COVID-19 patients develop long-haul symptoms. A 2021 study from Penn State University found that more than half of worldwide COVID-19 patients would develop long COVID.
Part of the discrepancy can blamed on the fact there is no official, widely accepted definition of long COVID. The Centers for Disease Control and Prevention has said it means patients who experience “new, returning, or ongoing health problems 4 or more weeks after an initial infection” the coronavirus. The UCLA study, meanwhile, included patients still having symptoms 60-90 days after infection.
Still, the UCLA research team looked at demographics and clinical characteristics in an attempt to develop effective treatments.
People with a history of hospitalization, diabetes, and higher body mass index were most likely to develop long COVID, the researchers said. The kind of insurance the patients had also seemed to be a factor, though the researchers didn’t offer a reason why.
“Surprisingly, patients with commercial insurance had double the likelihood of developing [long COVID] compared to patients with Medicaid,” they wrote. “This association will be important to explore further to understand if insurance status in this group is representing unmeasured demographic factors or exposures.”
Older age and socioeconomic status were not associated with long COVID in the study – a surprise because those characteristics are often linked with severe illness and higher risk of death from COVID-19.
Weaknesses in the study included the subjective nature of how patients rated their symptoms and the limited number of symptoms evaluated.
“This study illustrates the need to follow diverse patient populations ... to understand the long COVID disease trajectory and evaluate how individual factors such as preexisting comorbidities, sociodemographic factors, vaccination status and virus variant type affect type and persistence of long COVID symptoms,” said Sun Yoo, MD, health sciences assistant clinical professor at UCLA.

Scaly rash
Scaly plaques on sun-exposed skin with hyperpigmentation and dyspigmentation are classic signs of cutaneous lupus erythematosus (CLE). (The dyspigmentation seen in this case signaled that she likely had chronic cutaneous lupus erythematosus [CCLE]—a subtype of CLE.) At the patient’s follow-up primary care visit, her antinuclear antibodies titer was 1:1280 (≥ 1:160 is considered a positive test) and her 24-hour urine protein was 1188 mg (normal levels in adults, < 150 mg/d). In light of the patient’s joint pain, lab findings, and skin manifestations, she was also given a diagnosis of systemic lupus erythematosus (SLE).
Lupus erythematosus has an increased prevalence in women and typically occurs between the ages of 20 to 50 years.1 The incidence and prevalence of this condition is also greater in Black patients. CLE can either occur with SLE or independently. Patients with CLE should be monitored for the development of SLE. A diagnosis of CLE is based mainly on clinical features; biopsy is only indicated if there is a high degree of uncertainty.
Patients with CLE may suffer from a lower quality of life compared to patients with other dermatologic conditions due to the often disfiguring and disabling nature of the condition.1,2 Additionally, Black patients have an even higher chance of developing depressive symptoms associated with CCLE.2
Therapeutic management for CLE involves photoprotection by wearing sun-protective clothing, sunscreen, and limiting sun exposure.1 Initial treatment includes topical or intralesional corticosteroids, or topical calcineurin inhibitors. Systemic therapy is similar to that used for SLE. Oral glucocorticoids, and antimalarial agents are considered first-line systemic therapy.1 Second-line treatment includes methotrexate, mycophenolate mofetil, systemic retinoids, and azathioprine. Other immunosuppressive agents that are less commonly used include clofazimine, cyclophosphamide, and rituximab.1
The patient was treated sequentially with trials of oral azathioprine 50 mg bid, then prednisone 10 mg once daily, and then hydroxychloroquine 400 mg daily, without significant change in her condition. Additionally, topical steroids did not improve the patient’s symptoms. She was subsequently started on rituximab 1000 mg intravenously with a second dose repeated 2 weeks later, and another treatment 6 months after that. One year after her visit to the ED, the patient was experiencing marked improvement in her lesions.

The Empire strikes out against one physician’s homemade star fighter
The force is with Ukraine, always
Of all the things we could want from Star Wars, a lightsaber is at the top of the list. And someone is working on that. But second is probably the iconic X-wing. It was used to blow up the Death Star after all: Who wouldn’t want one?
A real-life star fighter may be outside our technological capabilities, but Dr. Akaki Lekiachvili of Atlanta has done the next best thing and constructed a two-thirds scale model to encourage kids to enter the sciences and, with the advent of the war in Ukraine, raise money for medical supplies to assist doctors in the embattled country. Perhaps unsurprisingly, Dr. Lekiachvili, originally from Georgia (the country, former Soviet republic, and previous target of Russian aggression in 2008), takes a dim view toward the invasion of Ukraine: “Russia is like the Evil Empire and Ukraine the Rebel Alliance.”
It’s been a long road finishing the X-Wing, as Dr. Lekiachvili started the project in 2016 and spent $60,000 on it, posting numerous updates on social media over that time, even attracting the attention of Luke Skywalker himself, actor Mark Hamill. Now that he’s done, he’s brought his model out to the public multiple times, delighting kids and adults alike. It can’t fly, but it has an engine and wheels so it can move, the wings can lock into attack position, the thrusters light up, and the voices of Obi-Wan Kenobi and R2-D2 guide children along as they sit in the cockpit.
Dr. Lekiachvili hopes to auction off his creation to a collector and donate the proceeds to Ukrainian charities, and we’re sure he’ll receive far more than the $60,000 he spent building his masterpiece. Now, if you’ll excuse us, we’re off to raid our bank accounts. We have a Death Star to destroy.
I’m a doctor, not a hologram
Telemedicine got a big boost during the early phase of the pandemic when hospitals and medical offices were off limits to anyone without COVID-19, but things have cooled off, telemedically speaking, since then. Well, NASA may have heated them up again. Or maybe it was Starfleet. Hmm, wait a second while we check. … No, it was NASA.
The space agency used the Microsoft Hololens Kinect camera and a personal computer with custom software from Aexa Aerospace to “holoport” NASA flight surgeon Josef Schmid up to the International Space Station, where he had a conversation with European Space Agency astronaut Thomas Pesquet, who wore an augmented reality headset that allowed him to see, hear, and interact with a 3D representation of the earthbound medical provider.
“Holoportation has been in use since at least 2016 by Microsoft, but this is the first use in such an extreme and remote environment such as space,” NASA said in a recent written statement, noting that the extreme house call took place on Oct. 8, 2021.
They seem to be forgetting about Star Trek, but we’ll let them slide on that one. Anyway, NASA didn’t share any details of the medical holoconversation – which may have strained the limits of HIPAA’s portability provisions – but Dr. Schmid described it as “a brand-new way of human exploration, where our human entity is able to travel off the planet. Our physical body is not there, but our human entity absolutely is there.”
Boldly doctoring where no doctor has gone before, you might say. You also might notice from the photo that Dr. Schmid went full Trekkie with a genuine Vulcan salute. Live long and prosper, Dr. Schmid. Live long and prosper.
Add electricity for umami
Salt makes everything taste better. Unfortunately, excess salt can cause problems for our bodies down the line, starting with high blood pressure and continuing on to heart disease and strokes. So how do we enjoy our deliciously salty foods without putting ourselves at risk? One answer may be electricity.
Researchers at Meiji University in Tokyo partnered with food and beverage maker Kirin to develop a set of electric chopsticks to boost the taste of salt in foods without the extra sodium. According to codeveloper and Meiji University professor Homei Miyashita, the device, worn like a watch with a wire attached to one of the chopsticks, “uses a weak electrical current to transmit sodium ions from food, through the chopsticks, to the mouth where they create a sense of saltines,” Reuters said.
In a country like Japan, where a lot of food is made with heavily sodium-based ingredients like miso and soy sauce, the average adult consumes 10 g of salt a day. That’s twice the recommended amount proposed by the World Health Organization. To not sacrifice bland food for better health, this device, which enhances the saltiness of the food consumed by 1.5 times, offers a fairly easy solution to a big public health crisis.
The chopsticks were tested by giving participants reduced-sodium miso soup. They told the researchers that the food was improved in “richness, sweetness, and overall tastiness,” the Guardian said.
Worried about having something electric in your mouth? Don’t worry. Kirin said in a statement that the electricity is very weak and not enough to affect the body.
The chopsticks are still in a prototype stage, but you may be able to get your pair as soon as next year. Until then, maybe be a little mindful of the salt.
Pet poop works in mysterious ways
We usually see it as a burden when our pets poop and pee in the house, but those bodily excretions may be able to tell us something about cancer-causing toxins running rampant in our homes.
Those toxins, known as aromatic amines, can be found in tobacco smoke and dyes used in make-up, textiles, and plastics. “Our findings suggest that pets are coming into contact with aromatic amines that leach from products in their household environment,” lead author Sridhar Chinthakindi, PhD, of NYU Langone Health, said in a statement from the university. “As these substances have been tied to bladder, colorectal, and other forms of cancer, our results may help explain why so many dogs and cats develop such diseases.”
Tobacco smoke was not the main source of the aromatic amines found in the poop and urine, but 70% of dogs and 80% of cats had these chemicals in their waste. The researchers looked for 30 types of aromatic amines plus nicotine in the sample and found 8. The chemical concentrations were much higher in cats than in dogs, possibly because of differences in exposure and metabolism between the two species, they suggested.
“If [pets] are getting exposed to toxins in our homes, then we had better take a closer look at our own exposure,” said senior author Kurunthachalam Kannan, PhD, of NYU Langone.
So the next time your pet poops or pees in the house, don’t get mad. Maybe they’re just trying to help you out by supplying some easy-to-collect samples.

A real-life star fighter may be outside our technological capabilities, but Dr. Akaki Lekiachvili of Atlanta has done the next best thing and constructed a two-thirds scale model to encourage kids to enter the sciences and, with the advent of the war in Ukraine, raise money for medical supplies to assist doctors in the embattled country. Perhaps unsurprisingly, Dr. Lekiachvili, originally from Georgia (the country, former Soviet republic, and previous target of Russian aggression in 2008), takes a dim view toward the invasion of Ukraine: “Russia is like the Evil Empire and Ukraine the Rebel Alliance.”
It’s been a long road finishing the X-Wing, as Dr. Lekiachvili started the project in 2016 and spent $60,000 on it, posting numerous updates on social media over that time, even attracting the attention of Luke Skywalker himself, actor Mark Hamill. Now that he’s done, he’s brought his model out to the public multiple times, delighting kids and adults alike. It can’t fly, but it has an engine and wheels so it can move, the wings can lock into attack position, the thrusters light up, and the voices of Obi-Wan Kenobi and R2-D2 guide children along as they sit in the cockpit.
Dr. Lekiachvili hopes to auction off his creation to a collector and donate the proceeds to Ukrainian charities, and we’re sure he’ll receive far more than the $60,000 he spent building his masterpiece. Now, if you’ll excuse us, we’re off to raid our bank accounts. We have a Death Star to destroy.
I’m a doctor, not a hologram
Telemedicine got a big boost during the early phase of the pandemic when hospitals and medical offices were off limits to anyone without COVID-19, but things have cooled off, telemedically speaking, since then. Well, NASA may have heated them up again. Or maybe it was Starfleet. Hmm, wait a second while we check. … No, it was NASA.
The space agency used the Microsoft Hololens Kinect camera and a personal computer with custom software from Aexa Aerospace to “holoport” NASA flight surgeon Josef Schmid up to the International Space Station, where he had a conversation with European Space Agency astronaut Thomas Pesquet, who wore an augmented reality headset that allowed him to see, hear, and interact with a 3D representation of the earthbound medical provider.
“Holoportation has been in use since at least 2016 by Microsoft, but this is the first use in such an extreme and remote environment such as space,” NASA said in a recent written statement, noting that the extreme house call took place on Oct. 8, 2021.
They seem to be forgetting about Star Trek, but we’ll let them slide on that one. Anyway, NASA didn’t share any details of the medical holoconversation – which may have strained the limits of HIPAA’s portability provisions – but Dr. Schmid described it as “a brand-new way of human exploration, where our human entity is able to travel off the planet. Our physical body is not there, but our human entity absolutely is there.”
Boldly doctoring where no doctor has gone before, you might say. You also might notice from the photo that Dr. Schmid went full Trekkie with a genuine Vulcan salute. Live long and prosper, Dr. Schmid. Live long and prosper.
Add electricity for umami
Salt makes everything taste better. Unfortunately, excess salt can cause problems for our bodies down the line, starting with high blood pressure and continuing on to heart disease and strokes. So how do we enjoy our deliciously salty foods without putting ourselves at risk? One answer may be electricity.
Researchers at Meiji University in Tokyo partnered with food and beverage maker Kirin to develop a set of electric chopsticks to boost the taste of salt in foods without the extra sodium. According to codeveloper and Meiji University professor Homei Miyashita, the device, worn like a watch with a wire attached to one of the chopsticks, “uses a weak electrical current to transmit sodium ions from food, through the chopsticks, to the mouth where they create a sense of saltines,” Reuters said.
In a country like Japan, where a lot of food is made with heavily sodium-based ingredients like miso and soy sauce, the average adult consumes 10 g of salt a day. That’s twice the recommended amount proposed by the World Health Organization. To not sacrifice bland food for better health, this device, which enhances the saltiness of the food consumed by 1.5 times, offers a fairly easy solution to a big public health crisis.
The chopsticks were tested by giving participants reduced-sodium miso soup. They told the researchers that the food was improved in “richness, sweetness, and overall tastiness,” the Guardian said.
Worried about having something electric in your mouth? Don’t worry. Kirin said in a statement that the electricity is very weak and not enough to affect the body.
The chopsticks are still in a prototype stage, but you may be able to get your pair as soon as next year. Until then, maybe be a little mindful of the salt.
Pet poop works in mysterious ways
We usually see it as a burden when our pets poop and pee in the house, but those bodily excretions may be able to tell us something about cancer-causing toxins running rampant in our homes.
Those toxins, known as aromatic amines, can be found in tobacco smoke and dyes used in make-up, textiles, and plastics. “Our findings suggest that pets are coming into contact with aromatic amines that leach from products in their household environment,” lead author Sridhar Chinthakindi, PhD, of NYU Langone Health, said in a statement from the university. “As these substances have been tied to bladder, colorectal, and other forms of cancer, our results may help explain why so many dogs and cats develop such diseases.”
Tobacco smoke was not the main source of the aromatic amines found in the poop and urine, but 70% of dogs and 80% of cats had these chemicals in their waste. The researchers looked for 30 types of aromatic amines plus nicotine in the sample and found 8. The chemical concentrations were much higher in cats than in dogs, possibly because of differences in exposure and metabolism between the two species, they suggested.
“If [pets] are getting exposed to toxins in our homes, then we had better take a closer look at our own exposure,” said senior author Kurunthachalam Kannan, PhD, of NYU Langone.
So the next time your pet poops or pees in the house, don’t get mad. Maybe they’re just trying to help you out by supplying some easy-to-collect samples.

Acid series: Trichloroacetic acid
– yet can be one of the most dangerous treatments in the hands of an untrained user.
TCA, in a clear colorless solution, is available in concentrations up to 100%, and has not been associated with allergic reactions or systemic toxicity. The available concentrations include those used for superficial depth peels (10%-30%), medium depth peels (35%-50%), and deep peels (greater than 50%).
TCA causes coagulation of the cellular membrane of epidermal proteins in the epidermis and, depending on the concentration, the dermis, which results in frosting of the skin. Repair of the epidermal cells induces resurfacing of the skin and neocollagenesis. TCA can be combined with other acids, including glycolic acid (Coleman peel), Jessner solution (Monheit peel), and solid CO2 (Brody peel). It has also been combined with lactic acid, mandelic acid, and salicylic acid in combination peels of various concentrations.
Although there are many studies, case reports, and textbooks related to this topic and the applications, combinations and treatment options for TCA peels, it is important to highlight here how many of these solutions – at high concentrations – are available directly to consumers, med spas, and the general public through online websites, including Amazon and overseas sites. Over the last 15 years, I have seen complications of this acid alone in people who have bought TCA online, related to applications not just on the face but on the body, neck, eyes, vaginal, and anal areas. Pigmentation, erosions, ulcers, and strictures are just some of the possible complications that occur not just with a more concentrated solution, but more often from application errors, aggressive layering of the acid, allowing the acid to sit on the skin too long, and improper tissue prepping and posttreatment skin care.
TCA can be an untamable acid, with little control over the depth of penetration even in the most controlled situations. The inability to be neutralize TCA creates an environment in which the depth of penetration and tissue coagulation is not a precise science. Once applied, the tissue reaction cannot be “stopped” or rapidly reversed making it highly variable in its mechanism. Patients of all skin types have the potential to develop complications as the epidermal and dermal thickness, moisture content, sebum production, and pigmentation are highly varied between individuals.
In my opinion, it is a dangerous product to have on the market – not just for the untrained medical providers using it but for estheticians and the general public who now can buy TCA anywhere.
But with effective training, reliable sourcing and appropriate preparation of the patient’s skin, however, a TCA peel can be a highly effective tool for difficult-to-treat dermatological problems, such as scarring and xanthelasma.
