Journal of Clinical Outcomes Management

When Sigmund Freud claimed that “anatomy is destiny” he was referring to anatomical sex as a determinant of personality traits. Expert consensus statements have previously offered some recommendations for managing these syndromes, but clinical data are scarce, so the present review “is intended to establish a starting point for future research,”

That notion has been widely discredited, but Freud appears to be inadvertently right in one respect: When it comes to chronic obstructive pulmonary disease (COPD), anatomy really is destiny, and sex may be as well, pulmonary researchers say.

There is a growing body of evidence to indicate that COPD affects men and women differently, and that men and women patients with COPD require different clinical management. Yet women are often underdiagnosed or misdiagnosed, partly because of poorly understood sex differences, but also because of cultural biases.

But plunging any farther into the weeds, it’s important to define terms. Although various investigators have used the terms “sex” and “gender” interchangeably, sex is the preferred term when referring to biological attributes of individual patients, while gender refers to personal identity.

These distinctions are important, contended Amik Sodhi, MBBS, MPH, from the division of allergy, pulmonology, and critical care medicine at the University of Wisconsin–Madison.

“Sex is essentially a biologic construct, so it’s got to do with the sex chromosomes, the genetics of that person, and it refers to the anatomic variations that can change susceptibility to different diseases,” she said in an interview.

An example of sex differences or “sexual dimorphism” can be found in a recent meta-analysis of sex-based genetic associations by Megan Hardin, MD, MPH from Brigham & Women’s Hospital in Boston and colleagues.

They reported that CELSR1, a gene involved in fetal lung development, was expressed more among women than among men and that a single nucleotide polymorphism in the gene was associated with COPD among women smokers, but not among men smokers.

The finding points to a potential risk locus for COPD in women, and could help shed light on sexual dimorphism in COPD, Dr. Hardin and colleagues said.

In contrast to sex, “gender is more of a psychosocial construct which can impact how diseases manifest themselves, how they are potentially managed, and what outcomes might occur for that particular disease,” Dr. Sodhi said.

She and her colleagues recently published a review of sex and gender in common lung disorders and sleep in the journal CHEST, where they wrote that the “influence of sex and gender is portrayed in epidemiological data, disease pathogenesis and pathophysiology, clinical manifestations, response to treatment, access to care, and health outcomes. Hence, sex and gender should be considered in all types of research, clinical practice and educational curricula.”

For example, as previously reported at the 2021 annual meeting of the American Thoracic Society, sex-specific differences in the severity of symptoms and prevalence of comorbidities in patients with COPD may point to different criteria for diagnosing cardiac comorbidities in women and men.

Those conclusions came from a retrospective analysis of data on 795 women and 1,251 men with GOLD (Global Initiative for Chronic Obstructive Lung Disease) class 1-3 disease.

The investigators looked at the patients’ clinical history, comorbidities, lung function, COPD Assessment Test scores, and modified Medical Research Council (mMRC) dyspnea score, and found significant differences between men and women for most functional parameters and comorbidities, and for CAT items of cough, phlegm, and energy.

In logistic regression analysis, predictors for cardiac disease in men were energy, mMRC score, smoking status, body mass index, age, and spirometric lung function, but in women only age was significantly predictive for cardiac disease.

An example of gender effects on COPD differences in men and women is the increase in cigarette advertising aimed at women in the 1960s and the advent of women-targeted brands such as Virginia Slims, which in turn lead to increased smoking rates among women. In addition, in the developing world, where the sex/gender gap in COPD is narrowing, women tend to have greater exposure to wood smoke and cooking fuels in unventilated or poorly ventilated spaces, compared with men.
 

Increasing incidence among women

According to the Centers for Disease Control and Prevention, chronic lower respiratory diseases, primarily COPD, were the fourth-leading cause of death in women in the United States in 2018, following only heart disease, cancer, and accidents/injuries.

And as a CDC analysis of data from the 2013 Behavioral Risk Factor Surveillance System showed, women were more likely to report being told by a physician that they had COPD than did men (6.6%, compared with 5.4%).

Dr. Sodhi and colleagues noted that, at all time points examined from 2005 to 2014, women had a higher proportion than men of COPD hospitalizations and in-hospital deaths. They also noted that female sex is associated with a threefold risk for severe early-onset COPD, and that women with COPD have lower diffusion capacity of lungs for carbon monoxide, despite having higher predicted forced expiratory volume in 1 second, compared with men.

“Historically, COPD wasn’t a disease that was so prevalent in women. It’s been in the past 20 years that the trends have changed,” said Patricia Silveyra, MSc, PhD, ATSF, associate professor of environmental and occupational health at Indiana University, Bloomington.

The increasing prevalence of COPD among women cannot be explained by smoking alone, she said in an interview.

“It used to be thought that it was because more women smoked, but actually a lot of women who don’t smoke can develop COPD, so it appears to be probably something environmental, but because it used to be a disease of older men, in the clinic there was also a bias to diagnose men with COPD, and women with asthma, so a lot of women went underdiagnosed,” Dr. Silveyra said.

In their review, Dr. Sodhi and colleagues noted that women with COPD “may be underdiagnosed as a result of having different symptoms from those classically recognized. Reasons for underdiagnosis or a delay in diagnosis may also be due to lack of a formal evaluation with spirometry, women seeking care later in the course of disease, physician bias, or associated fatigue or depression misdirecting diagnostic strategies. Underdiagnosis may be associated with psychological distress and worse health-related quality of life.”

Although the evidence is mixed, women tend to present more frequently with the chronic bronchitis phenotype of COPD, compared with the emphysema phenotype, and women tend to have greater degrees of pulmonary function impairment when exposed to tobacco smoke, even after controlling for differences in height and weight.

“For the same amount of exposure to tobacco smoke, females are likely to develop more severe airflow limitation at an earlier age than males, and have more exacerbation,” Dr. Sodhi and colleagues wrote.

Both Dr. Silveyra and Dr. Sodhi said that reason why men and women differ in their physiological reactions to smoke are still unknown.
 

Sex differences in drug responses

There is only limited evidence to indicate that women and men respond differently to various therapeutic agents, but what is clear is that more research into this area is needed, Dr. Sodhi and Dr. Silveyra said.

For example, among the few studies that have documented sex differences, one showed no sex differences in the efficacy of salmeterol/fluticasone combination therapy for reducing exacerbations or improving quality of life, whereas another showed that women were more likely than men to experience COPD symptoms or exacerbations after stopping inhaled corticosteroids, Dr. Sodhi and colleagues noted.

Both Dr. Sodhi and Dr. Silveyra emphasized the need for clinical trials that study the effects of sex on treatment outcomes in COPD, which could lead to better, more personalized therapeutic regimens that take sex and gender into account.

Dr. Sodhi and colleagues offered the following advice to clinicians: “Interaction with female patients should take into account that their symptoms may not conform to traditionally accepted presentations. Challenges exist for female patients at all levels of health care interaction and as clinicians we need to acknowledge the bias and willfully work toward recognition and elimination of unconscious and conscious bias. Empowering our patients to have frank discussions with their health care team when they perceive bias is another step to help promote equity.”

The review by Dr. Sodhi and colleagues was supported by grants from the National Institutes of Health. Dr. Sodhi and Dr. Silveyra reported having no conflicts of interest to disclose.

The decline in new cases of child COVID-19 in the last week continued at about the same, somewhat slower pace as the week before, but admissions have moved upward slightly, according to the most recent data.

The total number of new cases came to 25,915 for the week of April 1-7, down by 5.8% from the previous week’s 27,521, which, in turn, was 5.2% lower than a week earlier, according to the American Academy of Pediatrics and the Children’s Hospital Association, which have been collecting COVID-related data from state and territorial health departments since the early stages of the pandemic. New case declines in previous weeks had ranged from 9.3% to 46%.

The nearly 26,000 cases reported during the first week of April represent a fall of 97.7% from the peak of the Omicron surge in mid-January, when weekly cases hit 1.15 million, and they represent the lowest weekly count since mid-July of 2021. Cumulative cases in children now number close to 12.9 million over the course of the pandemic, which is 19.0% of cases among all ages, the AAP and CHA said in their weekly COVID report.

Data on new-case rates from the Centers for Disease Control and Prevention show the same continued decline, but the CDC acknowledges the possibility of reporting delays in recent weeks. The numbers for the latest week, April 3-9, maintain the larger overall decline, but there have been a couple of small, temporary increases over the last month, the CDC reported on its COVID Data Tracker.

Daily new admissions of children aged 0-17 years with confirmed COVID were right around 0.14 per 100,000 population for April 3-9, compared with 0.13 per 100,000 during the week ending April 2, the CDC said, with reporting delays making it possible that the 0.14 figure could be revised upward in the near future. The highest admission rate, 1.25 children per 100,000 population, occurred on Jan. 15 and 16.

The latest on vaccination

New vaccinations slipped a bit in the last week, with the drop slightly larger among those aged 12-17 years – from 47,000 for the week of March 24-30 to 43,000 during March 31 to April 6 – than in children aged 5-11, who went from 70,000 initial doses to 69,000 over the same 2-week period, the AAP said in its weekly report on vaccination trends.

Among the states, Vermont has fully vaccinated more children aged 5-11 (58%) than any other state, while Hawaii is the leader in fully vaccinated 12- to 17-year-olds at 86%. The lowest comparable figures for both groups can be found in Alabama, where 10% of children aged 5-11 are fully vaccinated and 34% of those aged 12-17 have received both doses of the Pfizer-BioNTech vaccine, the AAP said.

National figures show equally large COVID vaccination gaps between the two age groups. As of April 11, 68% of all children aged 12-17 years had received at least one dose, compared with 34.6% of those aged 5-11, and 58.5% of the older group was fully vaccinated, versus 28.0% of the 5- to 11-year-olds, the CDC reported.

What causes the dramatic alterations in subjective awareness experienced during a psychedelic “trip?” A new study maps anatomical changes in specific neurotransmitter systems and brain regions that may be responsible for these effects.

Investigators gathered more than 6,800 accounts from individuals who had taken one of 27 different psychedelic compounds. Using a machine learning strategy, they extracted commonly used words from these testimonials, linking them with 40 different neurotransmitter subtypes that had likely induced these experiences.

The investigators then linked these subjective experiences with specific brain regions where the receptor combinations are most commonly found and, using gene transcription probes, created a 3D whole-brain map of the brain receptors and the subjective experiences linked to them.

“Hallucinogenic drugs may very well turn out to be the next big thing to improve clinical care of major mental health conditions,” senior author Danilo Bzdok, MD, PhD, associate professor, McGill University, Montreal, said in a press release.

“Our study provides a first step, a proof of principle, that we may be able to build machine-learning systems in the future that can accurately predict which neurotransmitter receptor combinations need to be stimulated to induce a specific state of conscious experience in a given person,” said Dr. Bzdok, who is also the Canada CIFAR AI Chair at Mila-Quebec Artificial Intelligence Institute.

The study was published online  in Science Advances.
 

‘Unique window’

Psychedelic drugs “show promise” as treatments for various psychiatric disorders, but subjective alterations of reality are “highly variable across individuals” and this “poses a key challenge as we venture to bring hallucinogenic substances into medical practice,” the investigators note.

Although the 5-HT2A receptor has been regarded as a “putative essential mechanism” of hallucinogenic experiences, it is unclear whether the experiential differences are explained by functional selectivity at the 5-HT2A receptor itself or “orchestrated by the vast array of neurotransmitter receptor subclasses on which these drugs act,” they add.

Lead author Galen Ballentine, MD, psychiatry resident, SUNY Downstate Medical Center, Brooklyn, told this news organization that he was “personally eager to find novel ways to identify the neurobiological underpinnings of different states of conscious awareness.”

Psychedelics, he said, offer a “unique window into a vast array of unusual states of consciousness and are particularly useful because they can point toward underlying mechanistic processes that are initiated in specific areas of receptor expression.”

The investigators wanted to understand “how these drugs work in order to help guide their use in clinical practice,” Dr. Ballentine said.

To explore the issue, they undertook the “largest investigation to date into the neuroscience of psychedelic drug experiences,” Dr. Ballentine said. “While most studies are limited to a single drug on a handful of subjects, this project integrates thousands of experiences induced by dozens of different hallucinogenic compounds, viewing them through the prism of 40 receptor subtypes.”
 

Unique neurotransmitter fingerprint

The researchers analyzed 6,850 experience reports of people who had taken 1 of 27 psychedelic compounds. The reports were drawn from a database hosted by the Erowid Center, an organization that collects first-hand accounts of experiences elicited by psychoactive drugs.

The researchers constructed a “bag-of-words” encoding of the text descriptions in each testimonial. Using linguistic calculation methods, they derived a final vocabulary of 14,410 words that they analyzed for descriptive experiential terms.

To shed light on the spatial distribution of these compounds that modulate neuronal activity during subjective “trips,” they compared normalized measurements of their relative binding strengths in 40 sites.

• 5-HT (5-HT2A, 5-HT2C, 5-HT2B, 5-HT1A, 5-HT1B, 5-HT1D, 5-HT1E, 5-HT5A, 5-HT6, 5-HT7)
• Dopamine (D1, D2, D3, D4, D5)
• Adrenergic (a-1A, a-1B, a-2A, a-2B, a-2C, b-1, b-2)
• Serotonin transporter (SERT)
• Dopamine transporter (DAT)
• Norepinephrine transporter (NET)
• Imidazoline-1 receptor (I1)
• Sigma receptors (s-1, s-2)
• d-opioid receptor (DOR)
• k-opioid receptor (KOR)
• m-opioid receptor (MOR)
• Muscarinic receptors (M1, M2, M3, M4, M5)
• Histamine receptors (H1, H2)
• Calcium ion channel (CA+)
• NMDA glutamate receptor

To map receptor-experience factors to regional levels of receptor gene transcription, they utilized human gene expression data drawn from the Allen Human Brain Atlas, as well as the Shafer-Yeo brain atlas.

Via a machine-learning algorithm, they dissected the “phenomenologically rich anecdotes” into a ranking of constituent brain-behavior factors, each of which was characterized by a “unique neurotransmitter fingerprint of action and a unique experiential context” and ultimately created a dimensional map of these neurotransmitter systems.
 

Data-driven framework

Cortex-wide distribution of receptor-experience factors was found in both deep and shallow anatomical brain regions. Regions involved in genetic factor expressions were also wide-ranging, spanning from higher association cortices to unimodal sensory cortices.

The dominant factor “elucidated mystical experience in general and the dissolution of self-world boundaries (ego dissolution) in particular,” the authors report, while the second- and third-most explanatory factors “evoked auditory, visual, and emotional themes of mental expansion.”

Ego dissolution was found to be most associated with the 5-HT2A receptor, as well as other serotonin receptors (5-HT2C, 5-HT1A, 5-HT2B), adrenergic receptors a-2A and b-2, and the D2 receptor.

Alterations in sensory perception were associated with expression of the 5-HT2A receptor in the visual cortex, while modulation of the salience network by dopamine and opioid receptors were implicated in the experience transcendence of space, time, and the structure of self. Auditory hallucinations were linked to a weighted blend of receptors expressed throughout the auditory cortex.

“This data-driven framework identifies patterns that undergird diverse psychedelic experiences such as mystical bliss, existential terror, and complex hallucinations,” Dr. Ballentine commented.

“Simultaneously subjective and neurobiological, these patterns align with the leading hypothesis that psychedelics temporarily diminish top-down control of the most evolutionarily advanced regions of the brain, while at the same time amplifying bottom-up sensory processing from primary sensory cortices,” he added.
 

Forging a new path

Scott Aaronson, MD, chief science officer, Institute for Advanced Diagnostics and Therapeutics and director of the Centre of Excellence at Sheppard Pratt, Towson, Md., said, “As we try to get our arms around understanding the implications of a psychedelic exposure, forward-thinking researchers like Dr. Bzdok et al. are offering interesting ways to capture and understand the experience.”

Dr. Aaronson, an adjunct professor at the University of Maryland School of Medicine who was not involved with the study, continued: “Using the rapidly developing field of natural language processing (NLP), which looks at how language is used for a deeper understanding of human experiences, and combining it with effects of psychedelic compounds on neuronal pathways and neurochemical receptor sites, the authors are forging a new path for further inquiry.” 

In an accompanying editorial, Daniel Barron, MD, PhD, medical director, Interventional Pain Psychiatry Program, Brigham and Women’s Hospital, Boston, and Richard Friedman, MD, professor of clinical psychiatry, Weill Cornell Medical College, New York, call the work “impressive” and “clever.”

“Psychedelics paired with new applications of computational tools might help bypass the imprecision of psychiatric diagnosis and connect measures of behavior to specific physiologic targets,” they write.

The number of overdose deaths in adolescents nearly doubled in 2020 from the year before and increased substantially again in 2021 after nearly a decade of fairly stable rates, according to data published in a JAMA research letter.

Most of the deaths involved fentanyl, the researchers found.

Joseph Friedman, MPH, of the Center for Social Medicine and Humanities at the University of California, Los Angeles, led the study, which analyzed adolescent (14-18 years old) overdose deaths in the United States from 2010 to June 2021 in light of increasing contamination in the supply of illicit drugs.

The researchers found there were 518 deaths among adolescents (2.40 per 100,000 population) in 2010, and the rates remained stable through 2019 with 492 deaths (2.36 per 100,000).

In 2020, however, deaths spiked to 954 (4.57 per 100 000), increasing by 94.3%, compared with 2019. In 2021, they increased another 20%.

The rise in fentanyl-involved deaths was particularly striking. Fentanyl-involved deaths increased from 253 (1.21 per 100,000) in 2019 to 680 (3.26 per 100,000) in 2020. The numbers through June 2021 were annualized for 2021 and calculations predicted 884 deaths (4.23 per 100,000) for the year.
 

Numbers point to fentanyl potency

In 2021, more than three-fourths (77.14%) of adolescent overdose deaths involved fentanyl, compared with 13.26% for benzodiazepines, 9.77% for methamphetamine, 7.33% for cocaine, 5.76% for prescription opioids, and 2.27% for heroin.

American Indian and Alaska Native adolescents had the highest overdose rate in 2021 (n = 24; 11.79 per 100,000), followed by Latinx adolescents (n = 354; 6.98 per 100,000).

“These adolescent trends fit a wider pattern of increasing racial and ethnic inequalities in overdose that deserve further investigation and intervention efforts,” the authors wrote.
 

Pandemic’s role unclear

The spikes in adolescent overdoses overlap the COVID-19 pandemic, but Dr. Friedman said in an interview the pandemic “may or may not have been a big factor. “

The authors wrote that drug use had generally been stable among adolescents between 2010 and 2020. The number of 10th graders reporting any illicit drug use was 30.2% in 2010 and 30.4% in 2020.

“So it’s not that more teens are using drugs. It’s just that drug use is becoming more dangerous due to the spread of counterfeit pills containing fentanyls,” Dr. Friedman said.

The authors noted that “the illicit drug supply has increasingly become contaminated with illicitly manufactured fentanyls and other synthetic opioid and benzodiazepine analogues.”

Mr. Friedman said the pandemic may have accelerated the spread of more dangerous forms of drugs as supply chains were disrupted.

Benjamin Brady, DrPH, an assistant professor at the University of Arizona, Tucson, who also has an appointment in the university’s Comprehensive Pain and Addiction Center, said in an interview the numbers that Dr. Friedman and colleagues present represent “worst fears coming true.”

He said he and his colleagues in the field “were anticipating a rise in overdose deaths for the next 5-10 years because of the way the supply-and-demand environment exists in the U.S.”

Dr. Brady explained that restricting access to prescription opioids has had an unfortunate side effect in decreasing access to a safer supply of drugs.

“Without having solutions that would reduce demand at the same rate, supply of the safer form of the drug has been reduced; that has pushed people toward heroin and street drugs and from 2016 on those have been adulterated with fentanyl,” he said.

He said the United States, compared with other developed nations, has been slower to embrace longer-term harm-reduction strategies and to improve access to treatment and care.

COVID likely also has exacerbated the problem in terms of isolation and reduction in quality of life that has adolescents seeking to fill that void with drugs, Dr. Brady said. They may be completely unaware that the drugs they are seeking are commonly cut with counterfeit fentanyl.

“Fentanyl can be up to 50 times stronger than heroin,” he noted. “Even just a little bit of fentanyl dramatically changes the risk profile on an overdose.”

Increasing rates of mental health concerns among adolescents over decades also contribute to drug-seeking trends, Dr. Brady noted.
 

Overdose increases in the overall population were smaller

In the overall population, the percentage increases were not nearly as large in 2020 and 2021 as they were for adolescents.

Rates of overdose deaths in the overall population increased steadily from 2010 and reached 70,630 in 2019. In 2020, the deaths increased to 91,799 (an increase of 29.48% from 2019) and increased 11.48% in 2021.

The researchers analyzed numbers from the Centers for Disease Control and Prevention WONDER (Wide-Ranging Online Data for Epidemiologic Research) database, which has records of all U.S. deaths for which drug overdose was listed as the underlying cause.

The authors and Dr. Brady report no relevant financial relationships.

Rates of overdose deaths in the overall population increased steadily from 2010 and reached 70,630 in 2019. In 2020, the deaths increased to 91,799 (an increase of 29.48% from 2019) and increased 11.48% in 2021.

The researchers analyzed numbers from the Centers for Disease Control and Prevention WONDER (Wide-Ranging Online Data for Epidemiologic Research) database, which has records of all U.S. deaths for which drug overdose was listed as the underlying cause.

The authors and Dr. Brady report no relevant financial relationships.

The number of overdose deaths in adolescents nearly doubled in 2020 from the year before and increased substantially again in 2021 after nearly a decade of fairly stable rates, according to data published in a JAMA research letter.

Most of the deaths involved fentanyl, the researchers found.

Joseph Friedman, MPH, of the Center for Social Medicine and Humanities at the University of California, Los Angeles, led the study, which analyzed adolescent (14-18 years old) overdose deaths in the United States from 2010 to June 2021 in light of increasing contamination in the supply of illicit drugs.

The researchers found there were 518 deaths among adolescents (2.40 per 100,000 population) in 2010, and the rates remained stable through 2019 with 492 deaths (2.36 per 100,000).

In 2020, however, deaths spiked to 954 (4.57 per 100 000), increasing by 94.3%, compared with 2019. In 2021, they increased another 20%.

The rise in fentanyl-involved deaths was particularly striking. Fentanyl-involved deaths increased from 253 (1.21 per 100,000) in 2019 to 680 (3.26 per 100,000) in 2020. The numbers through June 2021 were annualized for 2021 and calculations predicted 884 deaths (4.23 per 100,000) for the year.
 

Numbers point to fentanyl potency

In 2021, more than three-fourths (77.14%) of adolescent overdose deaths involved fentanyl, compared with 13.26% for benzodiazepines, 9.77% for methamphetamine, 7.33% for cocaine, 5.76% for prescription opioids, and 2.27% for heroin.

American Indian and Alaska Native adolescents had the highest overdose rate in 2021 (n = 24; 11.79 per 100,000), followed by Latinx adolescents (n = 354; 6.98 per 100,000).

“These adolescent trends fit a wider pattern of increasing racial and ethnic inequalities in overdose that deserve further investigation and intervention efforts,” the authors wrote.
 

Pandemic’s role unclear

The spikes in adolescent overdoses overlap the COVID-19 pandemic, but Dr. Friedman said in an interview the pandemic “may or may not have been a big factor. “

The authors wrote that drug use had generally been stable among adolescents between 2010 and 2020. The number of 10th graders reporting any illicit drug use was 30.2% in 2010 and 30.4% in 2020.

“So it’s not that more teens are using drugs. It’s just that drug use is becoming more dangerous due to the spread of counterfeit pills containing fentanyls,” Dr. Friedman said.

The authors noted that “the illicit drug supply has increasingly become contaminated with illicitly manufactured fentanyls and other synthetic opioid and benzodiazepine analogues.”

Mr. Friedman said the pandemic may have accelerated the spread of more dangerous forms of drugs as supply chains were disrupted.

Benjamin Brady, DrPH, an assistant professor at the University of Arizona, Tucson, who also has an appointment in the university’s Comprehensive Pain and Addiction Center, said in an interview the numbers that Dr. Friedman and colleagues present represent “worst fears coming true.”

He said he and his colleagues in the field “were anticipating a rise in overdose deaths for the next 5-10 years because of the way the supply-and-demand environment exists in the U.S.”

Dr. Brady explained that restricting access to prescription opioids has had an unfortunate side effect in decreasing access to a safer supply of drugs.

“Without having solutions that would reduce demand at the same rate, supply of the safer form of the drug has been reduced; that has pushed people toward heroin and street drugs and from 2016 on those have been adulterated with fentanyl,” he said.

He said the United States, compared with other developed nations, has been slower to embrace longer-term harm-reduction strategies and to improve access to treatment and care.

COVID likely also has exacerbated the problem in terms of isolation and reduction in quality of life that has adolescents seeking to fill that void with drugs, Dr. Brady said. They may be completely unaware that the drugs they are seeking are commonly cut with counterfeit fentanyl.

“Fentanyl can be up to 50 times stronger than heroin,” he noted. “Even just a little bit of fentanyl dramatically changes the risk profile on an overdose.”

Increasing rates of mental health concerns among adolescents over decades also contribute to drug-seeking trends, Dr. Brady noted.

Similar outcomes in patients with ventilator-associated pneumonia (VAP) suggest that antibiotics selected by Gram staining were noninferior to those based on guidelines and also significantly decreased the use of broad-spectrum antibiotics in this patient population.

The findings were published  in JAMA Network Open. The multicenter, open-label, noninferiority, randomized trial, Gram Stain-Guided Antibiotics Choice for VAP (GRACE-VAP), was conducted for 2 years in intensive care units (ICUs) of a dozen tertiary referral hospitals in Japan, from April 1, 2018, through May 31, 2020.

The authors noted in their paper that the 2016 clinical practice guidelines for VAP published by the Infectious Diseases Society of America (IDSA) and the American Thoracic Society recommend antibiotic agents active against both methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa as an empirical treatment. Adherence to these guidelines may lead to overuse of broad-spectrum antibiotic agents and could be associated with the accelerated emergence of antimicrobial-resistant organisms, the authors postulated.

The study sought to answer the question: Can Gram staining be used as an alternative to established guidelines to direct antibiotic use – thereby curbing the use of broad-spectrum antibiotics – without compromising patient safety and clinical outcomes?

A total of 206 patients, with a mean age of 69, took part in the study. The same number of patients were assigned to each arm. Patients aged 15 years or older with a VAP diagnosis and a modified Clinical Pulmonary Infection Score of 5 or higher were included.

Investigators reported that 79 patients (76.7%) responded to antibiotics in the Gram stain-guided group and 74 (71.8%) responded in the guideline-based group (risk difference, 0.05; 95% confidence interval, –0.07 to 0.17; P < .001, for noninferiority).

There was a decrease in antipseudomonal agent use comparing the Gram stain-guided group with the guideline-based group (30.1%; 95% CI, 21.5% to 39.9%; P < .001). There also was a decrease in anti-MRSA agents in the Gram stain-guided group, compared with the guideline-based group (38.8%; 95% CI, 29.4% to 48.9%; P < .001).

The 28-day cumulative incidence of mortality was 13.6% (n = 14) in the Gram stain-guided group versus 17.5% (n = 18) in the guideline-based group. Escalation of antibiotics according to culture results was performed in seven patients (6.8%) in the Gram stain-guided group and in one patient (1.0%) in the guideline-based group. No significant differences in study arms were observed on other measures, such as ICU-free days, ventilator-free days, and adverse events.

The authors concluded that their findings support the use of Gram staining as a strategy to manage infectious diseases and contain the development of multidrug resistant organisms (MDROs) in the setting of critical care.

“In the GRACE-VAP trial, we used the time-honored Gram stain technique as part of the daily management of infectious diseases. We believe that the trial results are acceptable and have the potential to change the strategy of antibiotic choice worldwide,” the authors wrote.

Benjamin D. Galvan MLS(ASCP), CIC, an infection preventionist with a professional background in clinical microbiology, noted that Gram staining is more accessible and significantly less costly than the rapid polymerase chain reaction testing certain institutions use to rapidly identify MDROs to help tailor therapy.

But one of the pitfalls with relying on Gram stain collection to guide antibiotic use is that it is operator dependent and subject to extrinsic factors, like prior antibiotic use, he pointed out.

“If it is not collected, set up, and read properly, the Gram stain is not going to necessarily be reliable” said Mr. Galvan, also a member of the national communications committee for the Association for Professionals in Infection Control and Epidemiology. He added that the sample in the study was not representative of institutions dealing with elevated rates of multidrug resistance.

“Even from their own results, they were looking at hospitals that have a low rate of multidrug resistance,” he said. “It was not clear if MRSA or just Staphylococcus aureus was identified in significant quantities upon review, and they recognized a lower-than-expected number of isolates of Pseudomonas aeruginosa.”

Establishing antibiotic treatment from the results of Gram-stain collection may not be sufficiently comprehensive, he said.

“Generally speaking, basing it (antibiotic therapy) solely off of a Gram stain is not looking at the whole picture,” said Mr. Galvan, noting that the 2016 IDSA guidelines call for an evaluation of the clinical status, including risk, of the individual patient, as well as locally available antibiotic resistance data.

Moreover, the evidence-based IDSA guidelines are in place to help address the issue of antimicrobial resistance trends, already recommending tailoring empiric antibiotic therapy based upon the levels of resistance in the local population, according to Galvan.

While the study suggests that this Gram-stain-driven tailoring of empiric antibiotic therapy may be noninferior to current guidelines in health care settings with low MDRO rates, its utility may not be suitable in hospitals that are already dealing with high rates of MDROs, such as Pseudomonas aeruginosa and Acinetobacter baumannii, or severe clinical cases of VAP, Mr. Galvan explained.

The researchers and Mr. Galvan disclosed no relevant financial relationships.

Early meniscal surgery does not appear to be better than a program of exercise and education in improving knee outcomes in young adults with meniscal tears, according to the results of the randomized controlled DREAM trial presented at the OARSI 2022 World Congress.

Indeed, similar clinically relevant improvements in knee pain, function, and quality of life at 12 months were seen among participants in both study arms.

“Our results highlight that decisions on surgery or nonsurgical treatment must depend on preferences and values and needs of the individuals consulting their surgeon,” Søren T. Skou, PT, MSc, PhD, reported during one of the opening sessions at the meeting sponsored by the Osteoarthritis Research Society International.

The lack of superiority was contrary to the expectations of the researchers who hypothesized that early surgical intervention in adults aged between 18 and 40 years would be more beneficial than an active rehabilitation program with later surgery if needed.

Although the results do tie in with the results of other trials and systematic reviews in older adults the reason for looking at young adults specifically, aside from the obvious differences and the origin of meniscal tears, was that no study had previously looked at this population, Dr. Skou explained.
 

Assembling the DREAM team

The DREAM (Danish RCT on Exercise versus Arthroscopic Meniscal Surgery for Young Adults) trial “was a collaborative effort among many clinicians in Denmark – physical therapists, exercise physiologists, and surgeons,” Dr. Skou observed.

In total, 121 adults with MRI-verified meniscal tears who were eligible for surgery were recruited and randomized to either the early meniscal surgery group (n = 60) or to the exercise and education group (n = 61). The mean age was just below 30 years and 28% were female

Meniscal surgery, which was either an arthroscopic partial meniscectomy or meniscal repair, was performed at seven specialist centers. The exercise and education program was delivered by trained physical therapists working at 19 participating centers. The latter consisted of 24 sessions of group-based exercise therapy and education held over a period of 12 weeks.

Participants randomized to the exercise and education arm had the option of later meniscal surgery, with one in four eventually undergoing this procedure.
 

No gain in pain

The primary outcome measure was the difference in the mean of four of the subscales of the Knee Injury and Osteoarthritis Outcome Score (KOOS4) from baseline to 12-month assessment. The KOOS4 looks at knee pain, symptoms, function in sport and recreation, and quality of life.

“We considered a 10-point difference between groups as clinically relevant,” said Dr. Skou, but “adjusting for the baseline differences, we found no [statistical] differences or clinically relevant differences between groups.”

Improvement was seen in both groups. In an intention-to-treat analysis the KOOS4 scores improved by 19.2 points and 16.4 points respectively in the surgery and exercise and education groups, with a mean adjusted difference of 5.4 (95% confidence interval, –0.7 to 11.4). There was also no difference in a per protocol analysis, which considered only those participants who received the treatment strategy they were allocated (mean adjusted difference, 5.7; 95% CI, –0.9 to 12.4).

Secondary outcomes were also similarly improved in both groups with clinically relevant increases in all four KOOS subscale scores and in the Western Ontario Meniscal Evaluation Tool (WOMET).

While there were some statistical differences between the groups, such as better KOOS pain, symptoms, and WOMET scores in the surgery group, these were felt unlikely to be clinically relevant. Likewise, there was a statistically greater improvement in muscle strength in the exercise and education group than surgery group.

There was no statistical difference in the number of serious adverse events, including worsening of symptoms with or without acute onset during activity and lateral meniscal cysts, with four reported in the surgical group and seven in the exercise and education group.
 

Views on results

The results of the trial, published in NEJM Evidence, garnered attention on Twitter with several physiotherapists noting the data were positive for the nonsurgical management of meniscal tears in younger adults.

During discussion at the meeting, Nadine Foster, PhD, NIHR Professor of Musculoskeletal Health in Primary Care at Keele (England) University, asked if a larger cohort might not swing the results in favor of surgery.

She said: “Congratulations on this trial. The challenge: Your 95% CIs suggest a larger trial would have concluded superiority of surgery?”

Dr. Skou responded: “Most likely the true difference is outside the clinically relevant difference, but obviously, we cannot exclude that there is actually a clinically relevant difference between groups.”

Martin Englund, MD, Phd, of Lund (Sweden) University Hospital in Sweden, pointed out that 16 patients in the exercise and education group had “crossed over” and undergone surgery. “Were there any differences for those patients?” he asked.

“We looked at whether there was a difference between those – obviously only having 16 participants, we’re not able to do any statistical comparisons – but looking just visually at the data, they seem to improve to the same extent as those undergoing nonsurgical only,” Dr. Skou said.

The 2-year MRI data are currently being examined and will “obviously also be very interesting,” he added.

The DREAM trial was funded by the Danish Council for Independent Research, IMK Almene Fond, Lundbeck Foundation, Spar Nord Foundation, Danish Rheumatism Association, Association of Danish Physiotherapists Research Fund, Research Council at Næstved-Slagelse-Ringsted Hospitals, and Region Zealand. Dr. Skou had no financial or other conflicts of interest to disclose.

The DREAM (Danish RCT on Exercise versus Arthroscopic Meniscal Surgery for Young Adults) trial “was a collaborative effort among many clinicians in Denmark – physical therapists, exercise physiologists, and surgeons,” Dr. Skou observed.

In total, 121 adults with MRI-verified meniscal tears who were eligible for surgery were recruited and randomized to either the early meniscal surgery group (n = 60) or to the exercise and education group (n = 61). The mean age was just below 30 years and 28% were female

Meniscal surgery, which was either an arthroscopic partial meniscectomy or meniscal repair, was performed at seven specialist centers. The exercise and education program was delivered by trained physical therapists working at 19 participating centers. The latter consisted of 24 sessions of group-based exercise therapy and education held over a period of 12 weeks.

Participants randomized to the exercise and education arm had the option of later meniscal surgery, with one in four eventually undergoing this procedure.
 

No gain in pain

The primary outcome measure was the difference in the mean of four of the subscales of the Knee Injury and Osteoarthritis Outcome Score (KOOS4) from baseline to 12-month assessment. The KOOS4 looks at knee pain, symptoms, function in sport and recreation, and quality of life.

“We considered a 10-point difference between groups as clinically relevant,” said Dr. Skou, but “adjusting for the baseline differences, we found no [statistical] differences or clinically relevant differences between groups.”

Improvement was seen in both groups. In an intention-to-treat analysis the KOOS4 scores improved by 19.2 points and 16.4 points respectively in the surgery and exercise and education groups, with a mean adjusted difference of 5.4 (95% confidence interval, –0.7 to 11.4). There was also no difference in a per protocol analysis, which considered only those participants who received the treatment strategy they were allocated (mean adjusted difference, 5.7; 95% CI, –0.9 to 12.4).

Secondary outcomes were also similarly improved in both groups with clinically relevant increases in all four KOOS subscale scores and in the Western Ontario Meniscal Evaluation Tool (WOMET).

While there were some statistical differences between the groups, such as better KOOS pain, symptoms, and WOMET scores in the surgery group, these were felt unlikely to be clinically relevant. Likewise, there was a statistically greater improvement in muscle strength in the exercise and education group than surgery group.

There was no statistical difference in the number of serious adverse events, including worsening of symptoms with or without acute onset during activity and lateral meniscal cysts, with four reported in the surgical group and seven in the exercise and education group.
 

Views on results

The results of the trial, published in NEJM Evidence, garnered attention on Twitter with several physiotherapists noting the data were positive for the nonsurgical management of meniscal tears in younger adults.

During discussion at the meeting, Nadine Foster, PhD, NIHR Professor of Musculoskeletal Health in Primary Care at Keele (England) University, asked if a larger cohort might not swing the results in favor of surgery.

She said: “Congratulations on this trial. The challenge: Your 95% CIs suggest a larger trial would have concluded superiority of surgery?”

Dr. Skou responded: “Most likely the true difference is outside the clinically relevant difference, but obviously, we cannot exclude that there is actually a clinically relevant difference between groups.”

Martin Englund, MD, Phd, of Lund (Sweden) University Hospital in Sweden, pointed out that 16 patients in the exercise and education group had “crossed over” and undergone surgery. “Were there any differences for those patients?” he asked.

“We looked at whether there was a difference between those – obviously only having 16 participants, we’re not able to do any statistical comparisons – but looking just visually at the data, they seem to improve to the same extent as those undergoing nonsurgical only,” Dr. Skou said.

The 2-year MRI data are currently being examined and will “obviously also be very interesting,” he added.

The DREAM trial was funded by the Danish Council for Independent Research, IMK Almene Fond, Lundbeck Foundation, Spar Nord Foundation, Danish Rheumatism Association, Association of Danish Physiotherapists Research Fund, Research Council at Næstved-Slagelse-Ringsted Hospitals, and Region Zealand. Dr. Skou had no financial or other conflicts of interest to disclose.

There’s a strong likelihood that the antidepressant fluvoxamine (Luvox) may moderately lower rates of hospitalization caused by COVID-19 in unvaccinated patients, a new systematic review and meta-analysis has found. But outside experts differ over whether the evidence from just three studies is strong enough to warrant adding the drug to the COVID-19 armamentarium.

The report, published online in JAMA Network Open, looked at three studies and estimated that the drug could reduce the relative risk of hospitalization by around 25% (likelihood of moderate effect, 81.6%-91.8%), depending on the type of analysis used.

“This research might be valuable, but the jury remains out until several other adequately powered and designed trials are completed,” said infectious disease specialist Carl J. Fichtenbaum, MD, of the University of Cincinnati, who’s familiar with the findings. “I’m not sure how useful this is given we have several antiviral agents available. Why would we choose this over Paxlovid, remdesivir, or molnupiravir?”

According to Dr. Fichtenbaum, researchers began focusing on fluvoxamine after case reports about patients improving while on the medication. This led to further interest, he said, boosted by the drug’s known ability to dampen the immune system.

A Silicon Valley investor and antivaccine activist named Steve Kirsch has been pushing the drug along with the debunked treatment hydroxychloroquine. He’s accused the government of a cover-up of fluvoxamine’s worth, according to MIT Technology Review, and he wrote a commentary that referred to the drug as “the fast, easy, safe, simple, low-cost solution to COVID that works 100% of the time that nobody wants to talk about.”

For the new analysis, researchers examined three randomized clinical trials with a total of 2,196 participants. The most extensive trial, the TOGETHER study in Brazil (n = 1,497), focused on an unusual outcome: It linked the drug to a 32% reduction in relative risk of patients with COVID-19 being hospitalized in an ED for fewer than 6 hours or transferred to a tertiary hospital because of the disease.

Another study, the STOP COVID 2 trial in the United States and Canada (n = 547), was stopped because too few patients could be recruited to provide useful results. The initial phase of this trial, STOP COVID 1 (n = 152), was also included in the analysis.

All participants in the three studies were unvaccinated. Their median age was 46-50 years, 55%-72% were women, and 44%-56% were obese. Most were multiracial due to the high number of participants from Brazil.

“In the Bayesian analyses, the pooled risk ratio in favor of fluvoxamine was 0.78 (95% confidence interval, 0.58-1.08) for the weakly neutral prior and 0.73 (95% CI, 0.53-1.01) for the moderately optimistic prior,” the researchers reported, referring to a reduction in risk of hospitalization. “In the frequentist meta-analysis, the pooled risk ratio in favor of fluvoxamine was 0.75 (95% CI, 0.58-0.97; I², 0.2%).”

Two of the authors of the new analysis were also coauthors of the TOGETHER trial and both STOP COVID trials.

Corresponding author Emily G. McDonald, MD, division of experimental medicine at McGill University, Montreal, said in an interview that the findings show fluvoxamine “very likely reduces hospitalization in high-risk outpatient adults with COVID-19. This effect varies depending on your baseline risk of developing complications in the first place.”

Dr. McDonald added that “fluvoxamine is an option to reduce hospitalizations in high-risk adults. It is likely effective, is inexpensive, and has a long safety track record.” She also noted that “not all countries have access to Paxlovid, and some people have drug interactions that preclude its use. Existing monoclonals are not effective with newer variants.”

The drug’s apparent anti-inflammatory properties seem to be key, she said. According to her, the next steps should be “testing lower doses to see if they remain effective, following patients long term to see what impact there is on long COVID symptoms, testing related medications in the drug class to see if they also show an effect, and testing in vaccinated people and with newer variants.”

In an interview, biostatistician James Watson, PhD, of the Mahidol Oxford Tropical Medicine Research Unit, Bangkok, Thailand, and Nuffield department of medicine, University of Oxford, England, said the findings of the analysis are “not overwhelming data.”

He noted the TOGETHER study’s unusual focus on ED visits that latest fewer than 6 hours, which he described as “not a very objective endpoint.” The new meta-analysis focused instead on “outcome data on emergency department visits lasting more than 24 hours and used this as a more representative proxy for hospital admission than an ED visit alone.”

Dr. Fichtenbaum also highlighted the odd endpoint. “Most of us would have chosen something like use of oxygen, requirement for ventilation, or death,” he said. “There are many reasons why people go to the ED. This endpoint is not very strong.”

He also noted that the three studies “are very different in design and endpoints.”

Jeffrey S. Morris, PhD, a biostatistician at the University of Pennsylvania, Philadelphia, offered a different perspective about the findings in an interview. “There’s good evidence that it helps some,” he said, and may reduce hospitalizations by 10%. “If the pill is super cheap and toxicity is very acceptable, it’s not adding additional risk. Most clinicians would say that: ‘If I’m reducing risk by 10%, it’s worthwhile.’ ”

No funding was reported. Two authors report having a patent application filed by Washington University for methods of treating COVID-19 during the conduct of the study. Dr. Watson is an investigator for studies analyzing antiviral drugs and Prozac as COVID-19 treatments. Dr. Fichtenbaum and Dr. Morris disclosed no relevant financial relationships.

Though overall COVID-19 case counts continue to drop nationally, that’s not the story in every U.S. state.

About half the states have reported increases in COVID cases fueled by the Omicron subvariant, Axios reported. Alaska, Vermont, and Rhode Island had the highest increases, with more than 20 new cases per 100,000 people.

Nationally, the statistics are encouraging, with the 7-day average of daily cases around 26,000 on April 6, down from around 41,000 on March 6, according to the Centers for Disease Control and Prevention. The number of deaths has dropped to an average of around 600 a day, down 34% from 2 weeks ago.

National health officials have said some spots would have a lot of COVID cases.

“Looking across the country, we see that 95% of counties are reporting low COVID-19 community levels, which represent over 97% of the U.S. population,” CDC Director Rochelle Walensky, MD, said April 5 at a White House news briefing.

“If we look more closely at the local level, we find a handful of counties where we are seeing increases in both cases and markers of more severe disease, like hospitalizations and in-patient bed capacity, which have resulted in an increased COVID-19 community level in some areas.”

Meanwhile, the Commonwealth Fund issued a report April 8 saying the U.S. vaccine program had prevented an estimated 2.2 million deaths and 17 million hospitalizations.

If the vaccine program didn’t exist, the United States would have had another 66 million COVID infections and spent about $900 billion more on health care, the foundation said.

The United States has reported about 982,000 COVID-related deaths so far with about 80 million COVID cases, according to the CDC.

“Our findings highlight the profound and ongoing impact of the vaccination program in reducing infections, hospitalizations, and deaths,” the Commonwealth Fund said.

“Investing in vaccination programs also has produced substantial cost savings – approximately the size of one-fifth of annual national health expenditures – by dramatically reducing the amount spent on COVID-19 hospitalizations.”

Physically fit children have a greater ability to concentrate and better health-related quality of life (HRQOL), according to a new study.

The findings of the German study involving more than 6,500 kids emphasize the importance of cardiorespiratory health in childhood, and support physical fitness initiatives in schools, according to lead author Katharina Köble, MSc, of the Technical University of Munich (Germany), and colleagues.

“Recent studies show that only a few children meet the recommendations of physical activity,” the investigators wrote in Journal of Clinical Medicine.

While the health benefits of physical activity are clearly documented, Ms. Köble and colleagues noted that typical measures of activity, such as accelerometers or self-reported questionnaires, are suboptimal research tools.

“Physical fitness is a more objective parameter to quantify when evaluating health promotion,” the investigators wrote. “Furthermore, cardiorespiratory fitness as part of physical fitness is more strongly related to risk factors of cardiovascular disease than physical activity.”

According to the investigators, physical fitness has also been linked with better concentration and HRQOL, but never in the same population of children.

The new study aimed to address this knowledge gap by assessing 6,533 healthy children aged 6-10 years, approximately half boys and half girls. Associations between physical fitness, concentration, and HRQOL were evaluated using multiple linear regression analysis in participants aged 9-10 years.

Physical fitness was measured using a series of challenges, including curl-ups (pull-ups with palms facing body), push-ups, standing long jump, handgrip strength measurement, and Progressive Aerobic Cardiovascular Endurance Run (PACER). Performing the multistage shuttle run, PACER, “requires participants to maintain the pace set by an audio signal, which progressively increases the intensity every minute.” Results of the PACER test were used to estimate VO_2max.

Concentration was measured using the d2-R test, “a paper-pencil cancellation test, where subjects have to cross out all ‘d’ letters with two dashes under a time limit.”

HRQOL was evaluated with the KINDL questionnaire, which covers emotional well-being, physical well-being, everyday functioning (school), friends, family, and self-esteem.

Analysis showed that physical fitness improved with age (P < .001), except for VO_2max in girls (P = .129). Concentration also improved with age (P < .001), while HRQOL did not (P = .179).

Among children aged 9-10 years, VO_2max scores were strongly associated with both HRQOL (P < .001) and concentration (P < .001).

“VO_2max was found to be one of the main factors influencing concentration levels and HRQOL dimensions in primary school children,” the investigators wrote. “Physical fitness, especially cardiorespiratory performance, should therefore be promoted more specifically in school settings to support the promotion of an overall healthy lifestyle in children and adolescents.”
 

Findings are having a real-word impact, according to researcher

In an interview, Ms. Köble noted that the findings are already having a real-world impact.

“We continued data assessment in the long-term and specifically adapted prevention programs in school to the needs of the school children we identified in our study,” she said. “Schools are partially offering specific movement and nutrition classes now.”

In addition, Ms. Köble and colleagues plan on educating teachers about the “urgent need for sufficient physical activity.”

“Academic performance should be considered as an additional health factor in future studies, as well as screen time and eating patterns, as all those variables showed interactions with physical fitness and concentration. In a subanalysis, we showed that children with better physical fitness and concentration values were those who usually went to higher education secondary schools,” they wrote.
 

VO_2max did not correlate with BMI

Gregory Weaver, MD, a pediatrician at Cleveland Clinic Children’s, voiced some concerns about the reliability of the findings. He noted that VO_2max did not correlate with body mass index or other measures of physical fitness, and that using the PACER test to estimate VO_2max may have skewed the association between physical fitness and concentration.

“It is quite conceivable that children who can maintain the focus to perform maximally on this test will also do well on other tests of attention/concentration,” Dr. Weaver said. “Most children I know would have a very difficult time performing a physical fitness test which requires them to match a recorded pace that slowly increases overtime. I’m not an expert in the area, but it is my understanding that usually VO_2max tests involve a treadmill which allows investigators to have complete control over pace.”

Dr. Weaver concluded that more work is needed to determine if physical fitness interventions can have a positive impact on HRQOL and concentration.

“I think the authors of this study attempted to ask an important question about the possible association between physical fitness and concentration among school aged children,” Dr. Weaver said in an interview. “But what is even more vital are studies demonstrating that a change in modifiable health factors like nutrition, physical fitness, or the built environment can improve quality of life. I was hoping the authors would show that an improvement in VO_2max over time resulted in an improvement in concentration. Frustratingly, that is not what this article demonstrates.”

The investigators and Dr. Weaver reported no conflicts of interest.

According to the investigators, physical fitness has also been linked with better concentration and HRQOL, but never in the same population of children.

The new study aimed to address this knowledge gap by assessing 6,533 healthy children aged 6-10 years, approximately half boys and half girls. Associations between physical fitness, concentration, and HRQOL were evaluated using multiple linear regression analysis in participants aged 9-10 years.

Physical fitness was measured using a series of challenges, including curl-ups (pull-ups with palms facing body), push-ups, standing long jump, handgrip strength measurement, and Progressive Aerobic Cardiovascular Endurance Run (PACER). Performing the multistage shuttle run, PACER, “requires participants to maintain the pace set by an audio signal, which progressively increases the intensity every minute.” Results of the PACER test were used to estimate VO_2max.

Concentration was measured using the d2-R test, “a paper-pencil cancellation test, where subjects have to cross out all ‘d’ letters with two dashes under a time limit.”

HRQOL was evaluated with the KINDL questionnaire, which covers emotional well-being, physical well-being, everyday functioning (school), friends, family, and self-esteem.

Analysis showed that physical fitness improved with age (P < .001), except for VO_2max in girls (P = .129). Concentration also improved with age (P < .001), while HRQOL did not (P = .179).

Among children aged 9-10 years, VO_2max scores were strongly associated with both HRQOL (P < .001) and concentration (P < .001).

“VO_2max was found to be one of the main factors influencing concentration levels and HRQOL dimensions in primary school children,” the investigators wrote. “Physical fitness, especially cardiorespiratory performance, should therefore be promoted more specifically in school settings to support the promotion of an overall healthy lifestyle in children and adolescents.”
 

Findings are having a real-word impact, according to researcher

In an interview, Ms. Köble noted that the findings are already having a real-world impact.

“We continued data assessment in the long-term and specifically adapted prevention programs in school to the needs of the school children we identified in our study,” she said. “Schools are partially offering specific movement and nutrition classes now.”

In addition, Ms. Köble and colleagues plan on educating teachers about the “urgent need for sufficient physical activity.”

“Academic performance should be considered as an additional health factor in future studies, as well as screen time and eating patterns, as all those variables showed interactions with physical fitness and concentration. In a subanalysis, we showed that children with better physical fitness and concentration values were those who usually went to higher education secondary schools,” they wrote.
 

VO_2max did not correlate with BMI

Gregory Weaver, MD, a pediatrician at Cleveland Clinic Children’s, voiced some concerns about the reliability of the findings. He noted that VO_2max did not correlate with body mass index or other measures of physical fitness, and that using the PACER test to estimate VO_2max may have skewed the association between physical fitness and concentration.

“It is quite conceivable that children who can maintain the focus to perform maximally on this test will also do well on other tests of attention/concentration,” Dr. Weaver said. “Most children I know would have a very difficult time performing a physical fitness test which requires them to match a recorded pace that slowly increases overtime. I’m not an expert in the area, but it is my understanding that usually VO_2max tests involve a treadmill which allows investigators to have complete control over pace.”

Dr. Weaver concluded that more work is needed to determine if physical fitness interventions can have a positive impact on HRQOL and concentration.

“I think the authors of this study attempted to ask an important question about the possible association between physical fitness and concentration among school aged children,” Dr. Weaver said in an interview. “But what is even more vital are studies demonstrating that a change in modifiable health factors like nutrition, physical fitness, or the built environment can improve quality of life. I was hoping the authors would show that an improvement in VO_2max over time resulted in an improvement in concentration. Frustratingly, that is not what this article demonstrates.”

The investigators and Dr. Weaver reported no conflicts of interest.

Physically fit children have a greater ability to concentrate and better health-related quality of life (HRQOL), according to a new study.

The findings of the German study involving more than 6,500 kids emphasize the importance of cardiorespiratory health in childhood, and support physical fitness initiatives in schools, according to lead author Katharina Köble, MSc, of the Technical University of Munich (Germany), and colleagues.

“Recent studies show that only a few children meet the recommendations of physical activity,” the investigators wrote in Journal of Clinical Medicine.

Health care facilities and providers should complete the transition to fully disposable duodenoscopes and those with disposable components, the U.S. Food and Drug Administration announced this week after an analysis of postmarket surveillance studies was completed.

The FDA’s directive updates its April 2020 recommendations on the subject. It cites concerns about cleaning fixed endcap duodenoscopes and the increasing availability of models that eliminate the need for reprocessing.

The announcement highlighted the potential for a dramatic difference in between-patient contamination risk, reducing it “by half or more as compared to reusable, or fixed endcaps.”

“Interim results from one duodenoscope model with a removable component show a contamination rate of just 0.5%, as compared to older duodenoscope models which had contamination rates as high as 6%,” the FDA writes.

Duodenoscopes are used in more than 500,000 procedures each year in the United States and are key in assessing and treating diseases and conditions of the pancreas and bile ducts.
 

Upgrade to new models to decrease infections

Manufacturers no longer market fixed endcap models in the United States, but some health care facilities continue to use them. The FDA recommends that all fixed endcap models be replaced.

The FDA says some manufacturers are offering replacement programs to upgrade to a model with a disposable component at no cost.

Two fully disposable models and five with disposable components have been cleared by the FDA. (One model is no longer marketed and thus not listed here.)

Fully Disposable:

Ambu Innovation GmbH, Duodenoscope model aScope Duodeno

Boston Scientific Corporation, EXALT Model D Single-Use Duodenoscope

Disposable Components:

Fujifilm Corporation, Duodenoscope model ED-580XT 

Olympus Medical Systems, Evis Exera III Duodenovideoscope Olympus TJF-Q190V 

Pentax Medical, Duodenoscope model ED34-i10T2 

Pentax Medical, Duodenoscope model ED32-i10 

Additionally, the failure to correctly reprocess a duodenoscope could result in tissue or fluid from one patient transferring to a subsequent patient.

“In rare cases, this can lead to patient-to-patient disease transmission,” the FDA says.
 

Postmarket surveillance studies

In 2015, the FDA ordered three manufacturers of reusable devices (Fujifilm, Olympus, and Pentax) to conduct postmarket surveillance studies to determine contamination rates after reprocessing.

In 2019, the FDA also ordered postmarket surveillance studies to the makers of duodenoscopes with disposable endcaps to verify that the new designs reduce the contamination rate.

The final results of the fixed endcap design indicate that contamination rates were as high as 6.6% with high-concern organisms after contamination. High-concern organisms are those more often associated with disease, such as E coli and Pseudomonas contamination.

“As a result, Pentax and Olympus are withdrawing their fixed endcap duodenoscopes from the market, and Fujifilm has completed withdrawal of its fixed endcap duodenoscope,” the FDA writes.

Studies are not yet complete for duodenoscopes with removable components. As of August 12, 2021, the Fujifilm ED-580XT duodenoscope with a removable cap had 57% of the samples required. Interim results indicate that no samples tested positive for enough low-concern organisms to indicate a reprocessing failure, and only 0.5% tested positive for high-concern organisms.

In addition to the contamination risk sampling, each manufacturer was ordered to do postmarket surveillance studies to evaluate whether staff could understand and follow the manufacturer’s reprocessing instructions in real-world health care settings.

According to the FDA, the results showed that users frequently had difficulty understanding and following the manufacturers’ instructions and were not able to successfully complete reprocessing with the older models.

However, the newer models had high user success rates for understanding instructions and correctly performing reprocessing tasks, the FDA says.
