500 more steps a day tied to 14% lower CVD risk in older adults
Older adults who added a quarter mile of steps to their day showed a reduction in risk of cardiovascular events by 14% within 4 years, according to a study in more than 400 individuals.
“Aging is such a dynamic process, but most studies of daily steps and step goals are conducted on younger populations,” lead author Erin E. Dooley, PhD, an epidemiologist at the University of Alabama at Birmingham, said in an interview.
The impact of more modest step goals in older adults has not been well studied, Dr. Dooley said.
The population in the current study ranged from 71 to 92 years, with an average age of 78 years. The older age and relatively short follow-up period show the importance of steps and physical activity in older adults, she said.
Dr. Dooley presented the study at the Epidemiology and Prevention/Lifestyle and Cardiometabolic Health meeting.
She and her colleagues analyzed a subsample of participants in Atherosclerosis Risk in Communities (ARIC) study, an ongoing study conducted by the National Heart, Lung, and Blood Institute. The study population included 452 adults for whom step data were available at visit 6 of the ARIC study between 2016 and 2017. Participants wore an accelerometer on the waist for at least 10 hours a day for at least 3 days. The mean age of the participants was 78.4 years, 59% were women, and 20% were Black.
Outcomes were measured through December 2019 and included fatal and nonfatal cardiovascular disease (CVD) events of coronary heart disease, stroke, and heart failure.
Overall, each additional 500 steps per day was linked to a 14% reduction in risk of a CVD event (hazard ratio, 0.86; 95% confidence interval, 0.76-0.98). The mean step count was 3,447 steps per day, and 34 participants (7.5%) experienced a CVD event over 1,269 person-years of follow-up.
The cumulative risk of CVD was significantly higher (11.5%) in the quartile of adults with the lowest step count (defined as fewer than 2,077 steps per day), compared with 3.5% in those with the highest step count (defined as at least 4,453 steps per day).
In addition, adults in the highest quartile of steps had a 77% reduced risk of a proximal CVD (within 3.5 years) event over the study period (HR, 0.23).
Additional research is needed to explore whether increased steps prevent or delay CVD and whether low step counts may be a biomarker for underlying disease, the researchers noted in their abstract.
However, the results support the value of even a modest increase in activity to reduce CVD risk in older adults.
Small steps may get patients started
Dr. Dooley said she was surprised at the degree of benefits on heart health from 500 steps, and noted that the findings have clinical implications.
“Steps may be a more understandable metric for physical activity for patients than talking about moderate to vigorous intensity physical activity,” she said in an interview. “While we do not want to diminish the importance of higher intensity physical activity, encouraging small increases in the number of daily steps can also have great benefits for heart health.
“Steps are counted using a variety of devices and phones, so it may be helpful for patients to show clinicians their activity during well visits,” Dr. Dooley said. “Walking may also be more manageable for people as it is low impact. Achievable goals are also important. This study suggests that, for older adults, around 3,000 steps or more was associated with reduced CVD risk,” although the greatest benefits were seen with the most active group who averaged 4,500 or more steps per day.
More research is needed to show how steps may change over time, and how this relates to CVD and heart health,” she said. “At this time, we only had a single measure of physical activity.”
Study fills research gap for older adults
“Currently, the majority of the literature exploring a relationship between physical activity and the risk for developing cardiovascular disease has evaluated all adults together, not only those who are 70 year of age and older,” Monica C. Serra, PhD, of the University of Texas, San Antonio, said in an interview. “This study allows us to start to target specific cardiovascular recommendations for older adults.”.
“It is always exciting to see results from physical activity studies that continue to support prior evidence that even small amounts of physical activity are beneficial to cardiovascular health,” said Dr. Serra, who is also vice chair of the program committee for the meeting. “These results suggest that even if only small additions in physical activity are achievable, they may have cumulative benefits in reducing cardiovascular disease risk.” For clinicians, the results also provide targets that are easy for patients to understand, said Dr. Serra. Daily step counts allow clinicians to provide specific and measurable goals to help their older patients increase physical activity.
“Small additions in total daily step counts may have clinically meaningful benefits to heart health, so promoting their patients to make any slight changes that are able to be consistently incorporated into their schedule should be encouraged. This may be best monitored by encouraging the use of an activity tracker,” she said.
Although the current study adds to the literature with objective measures of physical activity utilizing accelerometers, these devices are not as sensitive at picking up activities such as bicycling or swimming, which may be more appropriate for some older adults with mobility limitations and chronic conditions, Dr. Serra said. Additional research is needed to assess the impact of other activities on CVD in the older population.
The meeting was sponsored by the American Heart Association. The study received no outside funding. Dr. Dooley and Dr. Serra had no financial conflicts to disclose.

Sputum markers may predict remission in eosinophilic asthma
for patients with severe eosinophilic asthma. The finding was based on data from 52 individuals.
Although IL-5 therapies have been shown to be effective for improving asthma, patients’ responses vary, write Catherine Moermans, PhD, of Liège University, Belgium, and colleagues.
Biotherapies targeting IL-5 allow a tangible improvement of asthma. However, all patients do not respond the same way to these treatments, and reliable biomarkers for predicting treatment response are lacking, they say.
In an observational study published in the journal Chest, the researchers recruited 52 adults with severe asthma who began anti–IL-5 treatment at a single center. The primary outcome was remission of asthma.
Remission was defined as meeting all of the following criteria 1 year after therapy: no chronic treatment with oral corticosteroids; no exacerbation; asthma control questionnaire scores lower than 1.5 and/or asthma test greater than 19; forced expiratory volume in 1 second (FEV1) of at least 80% predicted; and/or improvement of FEV1 equal to or larger than 10%, and a blood eosinophil count lower than 300 cells/mL.
Prior to treatment, the researchers measured eosinophil peroxidase (EPX), immunoglobulin E (IgE), IL-3, IL-4, IL-5, IL-13, IL-25, IL-33, granulocyte-macrophage colony-stimulating factor (GM-CSF), thymic stromal lymphopoietin (TSLP), and eotaxin-1 levels in the sputum of each patient.
At follow-up, 11 patients met the criteria for remission. These patients had significantly higher sputum eosinophil counts, sputum macrophage counts, and lymphocyte counts at baseline, compared with those not in remission (P = .006, P = .02, and P = .04, respectively). Sputum neutrophil percentage levels were significantly lower in patients whose asthma was in remission, compared with those whose asthma was not in remission (P = .007).
At the protein level, remission patients also showed higher baseline levels of sputum eotaxin-1, TSLP, IL-5, EPX, and IgE protein, compared with patients who did not achieve remission (P = .046, P = .04, P = .002, P = .001, and P = .006, respectively).
Overall, EPX and IL-5 measures showed the best combination of sensitivity and specificity, as well as the best area under the curve, the researchers write.
Patients in remission were significantly more likely to be men (8 of 11 patients), a finding that reflected previous studies, the researchers write. The finding of eosinophilic inflammation associated with stronger response to anti–IL-5 therapy also reflected previous studies, but the current study showed that “with a comparable blood eosinophil level at baseline before biotherapy, the response can be highly variable.”
The study findings were limited by several factors, including the small sample size and the lack of a formal definition of remission. Other research needs include an analysis based on nonresponse or suboptimal response predictors, the researchers note.
The results suggest that sputum type 2 markers are potential predictors of remission after anti–IL-5 treatment in adults with severe eosinophilic asthma, although the results must be validated in a larger, multicenter cohort, they conclude.
The study was supported by GlaxoSmithKline and AstraZeneca. Several coauthors have relationships with these companies. Dr. Moermans has disclosed no relevant financial relationships.

Beware risk of sedatives for respiratory patients
Both asthma and chronic obstructive pulmonary disease can be challenging to diagnose, and medication-driven episodes of sedation or hypoventilation are often overlooked as causes of acute exacerbations in these conditions, according to a letter published in The Lancet Respiratory Medicine.
write Christos V. Chalitsios, PhD, of the University of Nottingham, England, and colleagues.
The authors note that exacerbations are the main complications of both asthma and COPD, and stress the importance of identifying causes and preventive strategies.
Sedatives such as opioids have been shown to depress respiratory drive, reduce muscle tone, and increase the risk of pneumonia, they write. The authors also propose that the risk of sedative-induced aspiration or hypoventilation would be associated with medications including pregabalin, gabapentin, and amitriptyline.
Other mechanisms may be involved in the association between sedatives and exacerbations in asthma and COPD. For example, sedative medications can suppress coughing, which may promote airway mucous compaction and possible infection, the authors write.
Most research involving prevention of asthma and COPD exacerbations has not addressed the potential impact of sedatives taken for reasons outside of obstructive lung disease, the authors say.
“Although the risk of sedation and hypoventilation events are known to be increased by opioids and antipsychotic drugs, there has not been a systematic assessment of commonly prescribed medications with potential respiratory side-effects, including gabapentin, amitriptyline, and pregabalin,” they write.
Polypharmacy is increasingly common and results in many patients with asthma or COPD presenting for treatment of acute exacerbations while on a combination of gabapentin, pregabalin, amitriptyline, and opioids, the authors note; “however, there is little data or disease-specific guidance on how best to manage this problem, which often starts with a prescription in primary care,” they write. Simply stopping sedatives is not an option for many patients given the addictive nature of these drugs and the unlikely resolution of the condition for which the drugs were prescribed, the authors say. However, “cautious dose reduction” of sedatives is possible once patients understand the reason, they add.
Clinicians may be able to suggest reduced doses and alternative treatments to patients with asthma and COPD while highlighting the risk of respiratory depression and polypharmacy – “potentially reducing the number of exacerbations of obstructive lung disease,” the authors conclude.
The study received no outside funding. The authors have disclosed no relevant financial relationships.

No sex bias seen in ACC 22 speaker introductions
Men making speaker introductions at the 2022 annual scientific sessions of the American College of Cardiology were similarly likely to use professional titles regardless of gender, while women making introductions were more likely to use professional titles overall, based on a review of more than 800 videos of last year’s presentations.
“Implicit sex bias in speaker introductions at major medical conferences can foster and drive sex-driven assumptions about the competency of the speaker,” corresponding author Ankur Kalra, MD, an interventional cardiologist at Franciscan Health, Lafayette, Ind., said in an interview. “This is particularly important as recent data have shown a welcome, though gradual increase in the number of women speakers at major cardiology scientific sessions.”
In a research letter published in JACC: Advances, the researchers reviewed 1,696 videos from the ACC meeting held in Washington in April 2022 compiled by ACC Anywhere, and identified the participants as either “introducers” or “speakers.”
The final analysis included 888 speaker-introducer dyads. The introducer population was 49.4% men and 50.6% women; the speaker population included 58.8% men and 41.2% women.
Overall, 77.9% of speakers were addressed professionally in the first mention, and 71.5% were addressed professionally throughout the introduction. When making introductions, full professors were significantly more likely to use nonprofessional address than associate professors, assistant professors, and trainees (28.7% vs. 18.2%, 10.8%, and 0%, respectively).
Regardless of the sex of the speaker, women making introductions were significantly more likely than men to use professional titles for the speaker on first reference and consistently (84.2% vs. 71.5% and 78.2% vs. 64.7%, respectively; P < 0.001 for both).
Men doing introductions used professional forms of address similarly for both men and women speakers on first reference and consistently (72.2% vs. 71.1% and 65.4% vs. 64.3%, respectively).
No significant difference appeared in the use of professional address by women introducing women speakers compared to women introducing men speakers on first reference and consistently (81.9% vs. 86.1% and 75.0% vs. 80.8%, respectively).
“There was no significant association of the formality of introductions with the speaker’s sex and rank,” the researchers noted.
The findings were limited by several factors, including a lack of self-identified sex data, restriction to a binary determination of sex, and a lack of race/ethnicity analysis, the authors noted. In addition, the study could not account for prior familiarity between introducers and speakers that might influence the introduction.
Findings show positive trend
Dr. Kalra was surprised by the study findings, but in a good way. “A recent study on speakers presenting at Internal Medicine grand rounds demonstrated significant sex-based differences in using professional titles for formal introductions for women speakers in comparison with men speakers,” he said in an interview. The current study researchers expected to find similar differences.
“To our pleasant surprise, there was no implicit sex bias in introductions at the ACC 22, as there was no significant difference in the use of professional forms of address by men introducers of women speakers compared with men introducers of men speakers,” he said. “Similarly, the percentage of professional forms of address by women introducers was similar for men and women speakers.”
Setting an example
“A platform like ACC 22 is a window into the world of cardiovascular disease professionals – it’s a snapshot of who we are and what ethos/principles/values we represent,” said Dr. Kalra. “How we introduce one another is a surrogate marker of the mutual respect we behold for one another; our characters are on display, and the world and our junior colleagues are watching. Modern-day cardiology departments and practices must be completely intolerant to subtle microaggressions. The important take-away for clinicians is that it could be that our surprising findings may be attributed to the increased dialogue on sex disparities in cardiology, which has made physicians more cognizant of subtle microaggressions.”
A larger sample size is needed to replicate the study findings, and Dr. Kalra and colleagues hope to include data from ACC’s 2023 meeting, held with the World Congress of Cardiology in March, for additional research in this area.
Time to close inclusion gaps
“The time is now to dive into all previous and current gaps in diversity and inclusion,” Roxana Mehran, MD, said in an interview. “We must understand what the data are, and disseminate and educate all in health care on these issues.”
Dr. Mehran said she was not surprised by the findings of the current study. “This has been my own feeling for many years, watching mostly men be given important roles, such as Grand Rounds Speaking engagements. Now we have the data, and I congratulate the authors for the hard work to dig this out.
“In all aspects, we need to look at the entire talent pool to choose leadership, speakers, and key opinion leaders, as well as principal investigators in clinical trials,” said Dr. Mehran. “This has long been given to our wonderful and talented male colleagues without any effort to look for women, and non-Whites to be given the opportunity to shine and share their talent.”
Looking ahead, “we must remain vigilant and close gaps in all aspects of medicine whether in delivering care, or in the work force; this needs intentional efforts by all.”
The study was funded by makeadent.org and the Ram and Sanjita Kalra Aavishqaar Fund. Dr. Kalra is the CEO and creative director of makeadent.org. The other authors had no financial conflicts to disclose. Dr. Mehran had no financial conflicts to disclose.
Men making speaker introductions at the 2022 annual scientific sessions of the American College of Cardiology were similarly likely to use professional titles regardless of gender, while women making introductions were more likely to use professional titles overall, based on a review of more than 800 videos of last year’s presentations.
“Implicit sex bias in speaker introductions at major medical conferences can foster and drive sex-driven assumptions about the competency of the speaker,” corresponding author Ankur Kalra, MD, an interventional cardiologist at Franciscan Health, Lafayette, Ind., said in an interview. “This is particularly important as recent data have shown a welcome, though gradual increase in the number of women speakers at major cardiology scientific sessions.”

Prone positioning curbs need for intubation in nonintubated COVID-19 patients
as indicated by data from a new meta-analysis of more than 2,000 individuals.
The use of prone positioning for nonintubated patients (so-called “awake prone positioning”) has been common since the early days of the COVID-19 pandemic. Prone positioning is more comfortable for patients, and it entails no additional cost. Also, awake prone positioning is less labor intensive than prone positioning for intubated patients, said Jie Li, PhD, in a presentation at the Critical Care Congress sponsored by the Society of Critical Care Medicine.
However, data on the specific benefits of prone positioning are lacking and contradictory, said Dr. Li, a respiratory care specialist at Rush University, Chicago.
Dr. Li and colleagues from a multinational research group found that outcomes were improved for patients who were treated with awake prone positioning – notably, fewer treatment failures at day 28 – but a pair of subsequent studies by other researchers showed contradictory outcomes.
For more definitive evidence, Dr. Li and colleagues conducted a systematic review and meta-analysis of 11 randomized, controlled trials and one unpublished study of awake prone positioning for patients with COVID-19. The studies were published between Jan. 1, 2020, and July 1, 2022, and included a total of 2,886 adult patients.
The primary outcome was the reported cumulative risk of intubation among nonintubated COVID-19 patients. Secondary outcomes included mortality, the need for escalating respiratory support, length of hospital length of stay, ICU admission, and adverse events.
Overall, awake prone positioning significantly reduced the intubation risk among nonintubated patients compared to standard care (risk ratio, 0.85).
A further subgroup analysis showed a significant reduction in risk for intubation among patients supported by high-flow nasal cannula or noninvasive ventilation (RR, 0.83).
However, no additional reduction in intubation risk occurred among patients who received conventional oxygen therapy (RR, 1.02).
Mortality rates were similar for patients who underwent awake prone positioning and those who underwent supine positioning (RR, 0.96), as was the need for additional respiratory support (RR, 1.03). The length of hospital stay, ICU admission, and adverse events were similar between the patients who underwent prone positioning and those who underwent supine positioning.
The findings were limited by several factors. There was a potential for confounding by disease severity, which may have increased the use of respiratory support devices, Li said in her presentation.
“Another factor we should not ignore is the daily duration of prone positioning,” said Dr. Li. More research is needed to identify which factors play the greatest roles in treatment success.
The current study was important in that it evaluated the current evidence of awake prone positioning, “particularly to identify the patients who benefit most from this treatment, in order to guide clinical practice,” Dr. Li said in an interview.
“Since early in the pandemic, awake prone positioning has been broadly utilized to treat patients with COVID-19,” she said. “In 2021, we published a multinational randomized controlled trial with over 1,100 patients enrolled and reported lower treatment failure. However, no significant differences of treatment failure were reported in several subsequent multicenter randomized, controlled trials published after our study.”
Dr. Li said she was not surprised by the findings, which reflect those of her team’s previously published meta-analysis. “The increased number of patients helps confirm our previous finding, even with the inclusion of several recently published randomized controlled trials,” she said.
For clinicians, “the current evidence supports the use of awake prone positioning for patients with COVID-19, particularly those who require advanced respiratory support from high-flow nasal cannula or noninvasive ventilation,” Dr. Li said.
The study received no outside funding. Dr. Li has relationships with AARC, Heyer, Aeorgen, the Rice Foundation, and Fisher & Paykel Healthcare.

FROM SCCM 2023
USPSTF recommends against routine herpes screening for asymptomatic teens and adults
Asymptomatic adults, teens, and pregnant women with no known history or symptoms of herpes infection need not undergo routine screening, according to the latest recommendation from the U.S. Preventive Services Task Force.
The 2023 recommendation reaffirms the conclusion from 2016, wrote Carol M. Mangione, MD, of the University of California, Los Angeles, and members of the task force.
“Currently, routine serologic screening for genital herpes is limited by the low predictive value of the widely available serologic screening tests and the expected high rate of false-positive results likely to occur with routine screening of asymptomatic persons in the U.S.,” the authors said.
In the recommendation, published in JAMA, the authors affirmed with moderate certainty and a grade D recommendation that the risks of routine screening for herpes simplex virus (HSV) in asymptomatic individuals outweigh the benefits.
The task force found no new evidence on the accuracy of serologic screening tests, the benefits of early detection and treatment, or on the harms of screening and treatment since the 2016 review of 17 studies in 19 publications, with data from more than 9,000 individuals.
Studies of the accuracy of serologic screening for herpes simplex virus-2 in the 2016 report mainly reflect populations with higher HSV-2 prevalence and are of limited applicability to the U.S. primary care population, the authors wrote. Evidence from the 2016 review also showed limited and inconsistent support for the early identification and treatment of HSV-2 in asymptomatic individuals, including those who were pregnant.
No new evidence has emerged since 2016 regarding harms of screening or treating genital herpes in asymptomatic individuals, the authors noted. “Based on previous evidence, the USPSTF estimated that using the widely available serologic tests for HSV-2, nearly 1 of every 2 diagnoses in the general U.S. primary care population could be false,” they said. The task force also concluded that the low accuracy of the current tests could prompt unnecessary treatment for individuals with false-positive diagnoses, as well as social and emotional harm for these individuals.
During a period of public comment from Aug. 16, 2022, to Sept. 12, 2022, individuals expressed concerns that the recommendation against routine screening showed a disinclination to take herpes seriously, and concerns that asymptomatic individuals could transmit the infection to sexual partners, the authors said. However, the estimated seroprevalence of HSV-1 and HSV-2 has declined in recent decades, and other comments supported the USPSTF’s analysis of the evidence and noted their consistency with current clinical practice.
The task force noted that research gaps remain and recognized the need to improve screening and treatment of genital herpes to prevent symptomatic episodes and transmission. Specifically, the USPSTF recommendation calls for more research to assess the accuracy of screening tests, to enroll more study participants from populations disproportionately affected by HSV, to examine the effect of behavioral counseling, and to clarify associations between HSV and pregnancy outcomes. In addition, the task force called for research to create an effective vaccine to prevent genital HSV infection and to develop a cure.
Targeted screening makes sense for now
“Given the frequency and severity of the range of diseases seen with HSV and the large proportion of persons who are asymptomatic, identifying carriers through type-specific serologic screening has long been considered a plausible strategy,” Mark D. Pearlman, MD, of the University of Michigan, Ann Arbor, wrote in an accompanying editorial.
However, accuracy of the currently available serology screening tests is low, and the adverse social and psychological effects and the impact on relationships for many asymptomatic individuals who test positive and may be incorrectly identified as infected remains a concern, said Dr. Pearlman.
Although some may be disagree about the value of routine serotesting for HSV-2 in asymptomatic individuals, other strategies can reduce the spread of infection and help those infected, he said.
Many experts continue to recommend targeted serotesting to high-risk populations, such as pregnant women whose nonpregnant partner is known to have genital or oral herpes and whose own infection status or serostatus is uncertain, said Dr. Pearlman. Other targeted strategies include screening individuals with recurrent or atypical genital symptoms and negative polymerase chain reaction assay or culture results, a clinical herpes diagnosis without laboratory confirmation, or those at increased risk because of a high number of sexual partners or a history of HIV infection, he said.
“Of note, the current CDC STI guidelines and ACOG both concur with the USPSTF that routine screening in the general population or routine screening during pregnancy are not recommended,” Dr. Pearlman said. Meanwhile, research efforts continue to help reduce the impact of HSV disease and development of a more effective testing methodology “might tip the balance in favor of routine screening” in the future, he emphasized.
The recommendations were supported by the Agency for Healthcare Research and Quality. The members of the task force received reimbursement for travel and an honorarium but had no other relevant financial conflicts to disclose. Dr. Pearlman had no financial conflicts to disclose.

“Given the frequency and severity of the range of diseases seen with HSV and the large proportion of persons who are asymptomatic, identifying carriers through type-specific serologic screening has long been considered a plausible strategy,” Mark D. Pearlman, MD, of the University of Michigan, Ann Arbor, wrote in an accompanying editorial.
However, accuracy of the currently available serology screening tests is low, and the adverse social and psychological effects and the impact on relationships for many asymptomatic individuals who test positive and may be incorrectly identified as infected remains a concern, said Dr. Pearlman.
Although some may be disagree about the value of routine serotesting for HSV-2 in asymptomatic individuals, other strategies can reduce the spread of infection and help those infected, he said.
Many experts continue to recommend targeted serotesting to high-risk populations, such as pregnant women whose nonpregnant partner is known to have genital or oral herpes and whose own infection status or serostatus is uncertain, said Dr. Pearlman. Other targeted strategies include screening individuals with recurrent or atypical genital symptoms and negative polymerase chain reaction assay or culture results, a clinical herpes diagnosis without laboratory confirmation, or those at increased risk because of a high number of sexual partners or a history of HIV infection, he said.
“Of note, the current CDC STI guidelines and ACOG both concur with the USPSTF that routine screening in the general population or routine screening during pregnancy are not recommended,” Dr. Pearlman said. Meanwhile, research efforts continue to help reduce the impact of HSV disease and development of a more effective testing methodology “might tip the balance in favor of routine screening” in the future, he emphasized.
The recommendations were supported by the Agency for Healthcare Research and Quality. The members of the task force received reimbursement for travel and an honorarium but had no other relevant financial conflicts to disclose. Dr. Pearlman had no financial conflicts to disclose.
Asymptomatic adults, teens, and pregnant women with no known history or symptoms of herpes infection need not undergo routine screening, according to the latest recommendation from the U.S. Preventive Services Task Force.
The 2023 recommendation reaffirms the conclusion from 2016, wrote Carol M. Mangione, MD, of the University of California, Los Angeles, and members of the task force.
“Currently, routine serologic screening for genital herpes is limited by the low predictive value of the widely available serologic screening tests and the expected high rate of false-positive results likely to occur with routine screening of asymptomatic persons in the U.S.,” the authors said.
In the recommendation, published in JAMA, the authors affirmed with moderate certainty and a grade D recommendation that the risks of routine screening for herpes simplex virus (HSV) in asymptomatic individuals outweigh the benefits.
The task force found no new evidence on the accuracy of serologic screening tests, the benefits of early detection and treatment, or on the harms of screening and treatment since the 2016 review of 17 studies in 19 publications, with data from more than 9,000 individuals.
Studies of the accuracy of serologic screening for herpes simplex virus-2 in the 2016 report mainly reflect populations with higher HSV-2 prevalence and are of limited applicability to the U.S. primary care population, the authors wrote. Evidence from the 2016 review also showed limited and inconsistent support for the early identification and treatment of HSV-2 in asymptomatic individuals, including those who were pregnant.
No new evidence has emerged since 2016 regarding harms of screening or treating genital herpes in asymptomatic individuals, the authors noted. “Based on previous evidence, the USPSTF estimated that using the widely available serologic tests for HSV-2, nearly 1 of every 2 diagnoses in the general U.S. primary care population could be false,” they said. The task force also concluded that the low accuracy of the current tests could prompt unnecessary treatment for individuals with false-positive diagnoses, as well as social and emotional harm for these individuals.
During a period of public comment from Aug. 16, 2022, to Sept. 12, 2022, individuals expressed concerns that the recommendation against routine screening showed a disinclination to take herpes seriously, and concerns that asymptomatic individuals could transmit the infection to sexual partners, the authors said. However, the estimated seroprevalence of HSV-1 and HSV-2 has declined in recent decades, and other comments supported the USPSTF’s analysis of the evidence and noted their consistency with current clinical practice.
The task force noted that research gaps remain and recognized the need to improve screening and treatment of genital herpes to prevent symptomatic episodes and transmission. Specifically, the USPSTF recommendation calls for more research to assess the accuracy of screening tests, to enroll more study participants from populations disproportionately affected by HSV, to examine the effect of behavioral counseling, and to clarify associations between HSV and pregnancy outcomes. In addition, the task force called for research to create an effective vaccine to prevent genital HSV infection and to develop a cure.

Bright light therapy boosts therapeutic response
Both depression and bipolar disorder are leading causes of disability worldwide, and data show that only 50%-60% of these patients respond to first-line antidepressants, wrote Alessandro Cuomo, MD, of the University of Siena Medical Center, Italy, and colleagues.
Bright light therapy (BLT) was originally introduced as a treatment for seasonal affective disorder, but its use has been expanded to treat nonseasonal depression and bipolar disorder, they said. However, the impact of BLT on depressive symptoms in bipolar depression in particular has not been examined, they noted.
In a study published in the Journal of Affective Disorders, the researchers identified 18 men and 23 women aged 18 years and older with bipolar depression based on DSM-5 criteria who had already been treated with antidepressants. The participants were randomized to antidepressants combined with BLT or antidepressants combined with red light exposure (controls). The participants were positioned at 30-80 cm from the 10,000-lux light source for 30 minutes daily. The mean age of the participants was 49.1 years.
The primary outcome was scores on the Montgomery-Åsberg Depression Scale (MADRS), Hamilton Depression Rating Scale (HAMD-17), and CGI-Severity of illness (CGI-S), Fatigue Severity Scale (FSS), and Quality of Life Scale (QOLS) after the 8 weeks of treatment.
After 4 weeks, MADRS scores and HAMD-17 scores were significantly lower in the treatment group, compared with the controls (20 and 18 vs. 27.5 and 24.9, respectively; P < .001). Quality of life scores increased in the treatment group, compared with controls, with median scores of 39 vs. 29.50, respectively.
After 8 weeks, the treatment group continued to show significant improvement, compared with the control group, with scores on the MADRS, HAMD-17, CGI-S, and QOLS of 14.0, 9.0, 1.0, and 62.0 vs. 16.0, 15.5, 2.0, and 40.0, respectively. No side effects were reported.
“From our findings, BLT [proved] particularly effective in bipolar patients without triggering any manic switch, as evidenced instead in some similar studies,” the researchers wrote in their discussion.
Although the mechanism of action for BLT remains unclear, the current study findings confirm the existing knowledge of BLT, they noted. The positive effect of BLT on quality of life “might be attributable to the ability of BLT to reduce the latency times of antidepressants and increase the production of serotonin and melatonin,” as shown in previous work, they said.
The study findings were limited by several factors including the small sample size, which prevents definitive conclusions about the effectiveness of BLT in combination with different antidepressants, and the heterogeneity of the antidepressant treatments, the researchers noted. Larger, prospective studies and randomized, controlled trials are needed, as are studies of special populations such as older adults or those with degenerative diseases, they said.
However, the results suggest BLT has value as a safe and effective treatment and a way to boost therapeutic response and reduce the impact of long-lasting therapies, they concluded.
The study received no outside funding. Dr. Cuomo disclosed serving as a consultant and/or a speaker for Angelini, Glaxo Smith Kline, Lundbeck, Janssen, Otsuka, Pfizer, and Recordati.

Maternal COVID-19 vaccine curbs infant infection
a new study shows.
Previous research has confirmed that COVID-19 neutralizing antibodies following maternal vaccination or maternal COVID-19 infection are present in umbilical cord blood, breast milk, and infant serum specimens, wrote Sarah C.J. Jorgensen, PharmD, MPH, of the University of Toronto, and colleagues in their article published in The BMJ.
In the study, the researchers identified maternal and newborn pairs using administrative databases from Canada. The study population included 8,809 infants aged younger than 6 months who were born between May 7, 2021, and March 31, 2022, and who underwent testing for COVID-19 between May 7, 2021, and September 5, 2022.
Maternal vaccination with the primary COVID-19 mRNA monovalent vaccine series was defined as two vaccine doses administered up to 14 days before delivery, with at least one of the doses after the conception date.
Maternal vaccination with the primary series plus one booster was defined as three doses administered up to 14 days before delivery, with at least one of these doses after the conception date.
The primary outcome was the presence of delta or omicron COVID-19 infection or hospital admission of the infants.
The study population included 99 COVID-19 cases with the delta variant (with 4,365 controls) and 1,501 cases with the omicron variant (with 4,847 controls).
Overall, the vaccine effectiveness of maternal doses was 95% against delta infection and 45% against omicron.
The effectiveness against hospital admission in cases of delta and omicron variants were 97% and 53%, respectively.
The effectiveness of three doses was 73% against omicron infant infection and 80% against omicron-related infant hospitalization. Data were not available for the effectiveness of three doses against the delta variant.
The effectiveness of two doses of vaccine against infant omicron infection was highest when mothers received the second dose during the third trimester of pregnancy, compared with during the first trimester or second trimester (53% vs. 47% and 53% vs. 37%, respectively).
Vaccine effectiveness with two doses against infant infection from omicron was highest in the first 8 weeks of life (57%), then decreased to 40% among infants after 16 weeks of age.
Although the study was not designed to assess the mechanism of action of the impact of maternal vaccination on infants, the current study results were consistent with other recent studies showing a reduction in infections and hospitalizations among infants whose mothers received COVID-19 vaccines during pregnancy, the researchers wrote in their discussion.
The findings were limited by several factors including the potential unmeasured confounders not available in databases, such as whether infants were breastfed, the researchers noted. Other limitations included a lack of data on home test results and the inability to assess the waning impact of the vaccine effectiveness against the delta variant because of the small number of delta cases, they said. However, the results suggest that the mRNA COVID-19 vaccine during pregnancy was moderately to highly effective for protection against omicron and delta infection and infection-related hospitalization – especially during the first 8 weeks of life.
Effectiveness is encouraging, but updates are needed
The effectiveness of maternal vaccination to prevent COVID-19 infection and related hospitalizations in infants is promising, especially since those younger than 6 months have no other source of vaccine protection against COVID-19 infection, wrote Dana Danino, MD, of Soroka University Medical Center, Israel, and Ilan Youngster, MD, of Shamir Medical Center, Israel, in an accompanying editorial also published in The BMJ.
They also noted that maternal vaccination during pregnancy is an established method of protecting infants from infections such as influenza and pertussis.
Data from previous studies show that most infants whose mothers were vaccinated against COVID-19 during pregnancy retained maternal antibodies at 6 months, “but evidence for protection against neonatal COVID-19 infection has been deficient,” they said.
The current study findings support the value of vaccination during pregnancy, and the findings were strengthened by the large study population, the editorialists wrote. However, whether the same effectiveness holds for other COVID-19 strains such as BQ.1, BQ.1.1, BF.7, XBB, and XBB.1 remains unknown, they said.
Other areas in need of exploration include the optimal timing of vaccination during pregnancy, the protective effects of a bivalent mRNA vaccine (vs. the primary monovalent vaccine in the current study), and the potential benefits of additional boosters, they added.
“Although Jorgenson and colleagues’ study reinforces the value of maternal vaccination against COVID-19 during pregnancy, more studies are needed to better inform vaccination recommendations in an evolving landscape of new SARS-CoV-2 strains and novel vaccines,” the editorialists concluded.
The study was supported by ICES, which is funded by an annual grant from the Ontario Ministry of Health and the Ministry of Long-term Care; the study also received funding from the Canadian Immunization Research Network and the Public Health Agency of Canada. Dr. Jorgensen and the editorialists had no financial conflicts to disclose.

Systemic sclerosis antibodies show link to interstitial lung disease in RA
Adults with rheumatoid arthritis or primary Sjogren’s syndrome plus interstitial lung disease had higher levels of systemic sclerosis–specific antibodies than those without lung disease, based on data from 101 individuals.
Systemic sclerosis (SSc) has been associated with the development of interstitial lung disease (ILD), but the prevalence of SSc autoantibodies in patients with rheumatoid arthritis (RA) and primary Sjogren’s syndrome (SS) has not been explored, wrote Vasilike Koulouri, MD, of Kapodistrian University of Athens, and colleagues.
In a study published in the Journal of Translational Autoimmunity, the researchers reviewed serum data from patients with RA and SS using immunoblot assays to determine the prevalence of SSc-specific and anti-Ro52 autoantibodies, both of which have been associated with ILD in SSc patients.
The study population included 28 RA patients with ILD, 32 RA patients without ILD, 9 primary SS patients with ILD, and 32 primary SS patients with no ILD. The mean age of the RA participants was 63.4 years, 70% were women, and the mean age at RA diagnosis was 50.2 years. The mean age of the primary SS group was 60.3 years, 87.8% were female, and the mean age at diagnosis was 52.7 years.
Overall, SSc-specific antibodies across all titers were detected more frequently in RA patients with ILD compared with those with no ILD, though not statistically significant (42.9% vs. 21.9%, P = .08). However, “This trend was mainly attributed to the statistically significant difference between the two groups at strong titers (25% vs. 3.1%, P = .01),” the researchers wrote. Notably, they added.
No significant differences appeared in the prevalence of SSc-specific or Ro52 autoantibodies between primary SS patients with and without ILD, which might be attributable in part to the increased prevalence of anticentromere antibodies in primary SS, the researchers said.
RA patients who were positive for SSc-specific antibodies at strong titers were significantly more likely to have respiratory abnormalities than those who were negative (87.5% vs. 47.2%, P = .04), but no such differences appeared in primary SS patients.
“Early detection of SSc antibodies could be important in clinical practice as it may mandate further diagnostic (for example, screening for pulmonary hypertension) and therapeutic approaches of these patients,” the researchers wrote in their discussion.
The study findings were limited by several factors, mainly the small sample size, but also the potential for false-positive results on antibody titers, lack of data on the clinical significance of medium autoantibody titers, and the lack of long-term follow-up data, the researchers noted.
However, the results suggest that many seropositive RA patients with evidence of ILD “may evolve to a clinically evident overlap of RA and SSc” that would benefit from targeted treatment, they concluded.
The study was supported by a grant from Novartis AG and by the Molecular Immunology and Clinical Applications Unit, Department of Physiology, School of Medicine, National and Kapodistrian University of Athens. The researchers had no financial conflicts to disclose.

In a study published in the Journal of Translational Autoimmunity, the researchers reviewed serum data from patients with RA and SS using immunoblot assays to determine the prevalence of SSc-specific and anti-Ro52 autoantibodies, both of which have been associated with ILD in SSc patients.
The study population included 28 RA patients with ILD, 32 RA patients without ILD, 9 primary SS patients with ILD, and 32 primary SS patients with no ILD. The mean age of the RA participants was 63.4 years, 70% were women, and the mean age at RA diagnosis was 50.2 years. The mean age of the primary SS group was 60.3 years, 87.8% were female, and the mean age at diagnosis was 52.7 years.
Overall, SSc-specific antibodies across all titers were detected more frequently in RA patients with ILD compared with those with no ILD, though not statistically significant (42.9% vs. 21.9%, P = .08). However, “This trend was mainly attributed to the statistically significant difference between the two groups at strong titers (25% vs. 3.1%, P = .01),” the researchers wrote. Notably, they added.
No significant differences appeared in the prevalence of SSc-specific or Ro52 autoantibodies between primary SS patients with and without ILD, which might be attributable in part to the increased prevalence of anticentromere antibodies in primary SS, the researchers said.
RA patients who were positive for SSc-specific antibodies at strong titers were significantly more likely to have respiratory abnormalities than those who were negative (87.5% vs. 47.2%, P = .04), but no such differences appeared in primary SS patients.
“Early detection of SSc antibodies could be important in clinical practice as it may mandate further diagnostic (for example, screening for pulmonary hypertension) and therapeutic approaches of these patients,” the researchers wrote in their discussion.
The study findings were limited by several factors, mainly the small sample size, but also the potential for false-positive results on antibody titers, lack of data on the clinical significance of medium autoantibody titers, and the lack of long-term follow-up data, the researchers noted.
However, the results suggest that many seropositive RA patients with evidence of ILD “may evolve to a clinically evident overlap of RA and SSc” that would benefit from targeted treatment, they concluded.
The study was supported by a grant from Novartis AG and by the Molecular Immunology and Clinical Applications Unit, Department of Physiology, School of Medicine, National and Kapodistrian University of Athens. The researchers had no financial conflicts to disclose.

Nearly 12% of PsA patients need musculoskeletal surgery
Among adults with psoriatic arthritis (PsA), 11.8% required at least one musculoskeletal surgery related to their disease, based on data from more than 1,500 individuals at the University of Toronto’s Psoriatic Arthritis Clinic.
“Despite optimal medical therapy to control systemic inflammation and preserve joint function, a subset of patients with PsA still require musculoskeletal (MSK) surgery for disease-related morbidity,” but data on the prevalence of MSK surgeries and the associated risk factors are lacking, wrote Timothy S.H. Kwok, MD, of the University of Toronto, and colleagues.
In a study published in The Journal of Rheumatology, the researchers reviewed data from a longitudinal cohort of 1,574 adults aged 18 years and older with PsA established at the Toronto clinic during 1978-2019.
Overall, 185 patients had 379 MSK surgeries related to PsA during the study period for a prevalence of 11.8%.
The most common procedures were arthrodesis and arthroplasty (27% for both). More than half (59%) of the surgeries were joint sacrificing, and 41% were joint retaining, and 57 procedures were revisions related to the primary surgery.
Among 1,018 patients with data complete enough for a multivariate analysis, including 71 PsA surgeries, factors significantly associated with an increased risk for surgery were a higher number of damaged joints (hazard ratio [HR], 1.03; P < .001), tender or swollen joints (HR, 1.04; P = .01), and the presence of nail lesions (HR, 2.08; P < .01). Other predictors of surgery were higher scores on the Health Assessment Questionnaire (HR, 2.01; P < .001), elevated erythrocyte sedimentation rate (HR, 2.37; P = .02), and HLA-B27 positivity (HR, 2.22; P = .048).
However, a higher score on the Psoriasis Area Severity Index was significantly associated with lower risk of surgery (HR, 0.88; P < .002) The use of biologics had no significant impact on MSK surgery, the researchers noted.
The high percentage of joint sacrificing surgeries suggests a high burden of MSK surgery in patients with PsA, the researchers wrote in their discussion. The current study supports findings from previous studies and highlights the potential limitations and need for improvement in the current medical treatment paradigm for PsA, they said.
The findings were limited by several factors, including the potential for referral bias of complex cases to the center, which might have caused overestimation of the number of surgeries. The similarity in surgeries specifically related to PsA and degenerative arthritis also makes overestimation of surgeries possible, the researchers noted.
However, the study is one of the largest known to evaluate the prevalence of risk factors for MSK surgery in PsA patients over a long period of time, and identified surgeries directly attributable to PsA, they said. The study ended prior to the onset of the COVID-19 pandemic, which increased the external validity of the findings, they added.
