Patients with psoriasis have a significantly increased risk of severe and rare infections, compared with the general population, according to a population-based cohort study of nearly 95,000 patients.

Although previous studies have shown a higher risk for comorbid conditions in people with psoriasis, compared with those without psoriasis, data on the occurrence of severe and rare infections in patients with psoriasis are limited, wrote Nikolai Loft, MD, of the department of dermatology and allergy, Copenhagen University Hospital, Gentofte, and colleagues.

Psoriasis patients are often treated with immunosuppressive therapies that may promote or aggravate infections; therefore, a better understanding of psoriasis and risk of infections is needed, they said. In a study published in the British Journal of Dermatology, Dr. Loft and his coinvestigators reviewed data on adults aged 18 years and older from the Danish National Patient Register between Jan. 1, 1997 and Dec. 31, 2018. The study population included 94,450 adults with psoriasis and 566,700 matched controls. Patients with any type of psoriasis and any degree of severity were included.

The primary outcome was the occurrence of severe infections, defined as those requiring assessment at a hospital, and rare infections, defined as HIV, TB, HBV, and HCV. The median age of the participants was 52.3 years, and slightly more than half were women.

Overall, the incidence rate of severe and rare infections among patients with any type of psoriasis was 3,104.9 per 100,000 person-years, compared with 2,381.1 for controls, with a hazard ratio, adjusted for gender, age, ethnicity, socioeconomic status, alcohol-related conditions, and Charlson comorbidity index (aHR) of 1.29.

For any infections resulting in hospitalization, the incidence rate was 2,005.1 vs. 1,531.8 per 100,000 person-years for patients with any type of psoriasis and controls, respectively.

The results were similar when severe infections and rare infections were analyzed separately. The incidence rate of severe infections was 3,080.6 and 2,364.4 per 100,000 person-years for patients with any psoriasis, compared with controls; the incidence rate for rare infections was 42.9 and 31.8 for all psoriasis patients and controls, respectively.

When the data were examined by psoriasis severity, the incidence rate of severe and rare infections among patients with severe psoriasis was 3,847.7 per 100,000 person-years, compared with 2,351.9 per 100,000 person years among controls (aHR, 1.58) and also higher than in patients with mild psoriasis. The incidence rate of severe and rare infections in patients with mild psoriasis (2,979.1 per 100,000 person-years) also was higher than in controls (aHR, 1.26).

Factors that might explain the increased infection risk with severe psoriasis include the altered immune environment in these patients, the researchers wrote in their discussion of the findings. Also, “patients with severe psoriasis are defined by their eligibility for systemics, either conventional or biologic,” and their increased infection risk may stem from these treatments, rather than disease severity itself, they noted.

The study findings were limited by several factors including the lack of data on such confounders as weight, body mass index, and smoking status, they added. Other limitations included potential surveillance bias because of greater TB screening, and the use of prescriptions, rather than the Psoriasis Area Severity Index, to define severity. However, the results were strengthened by the large sample size, and suggest that patients with any type of psoriasis have higher rates of any infection, severe or rare, than the general population, the researchers concluded.

Data show need for clinician vigilance

Based on the 2020 Census data, an estimated 7.55 million adults in the United States have psoriasis, David Robles, MD, said in an interview. “Patients with psoriasis have a high risk for multiple comorbid conditions including metabolic syndrome, which is characterized by obesity, hypertension, and dyslipidemia,” said Dr. Robles, a dermatologist in private practice in Pomona, Calif., who was not involved in the study. “Although these complications were previously attributed to diet and obesity, it has become clear that the proinflammatory cytokines associated with psoriasis may be playing an important role underlying the pathologic basis of these other comorbidities.”

There is an emerging body of literature “indicating that psoriasis is associated with an increased risk of infections,” he added. Research in this area is particularly important because of the increased risk of infections associated with many biologic and immune-modulating treatments for psoriasis, Dr. Robles noted.

The study findings “indicate that, as the severity of psoriasis increases, so does the risk of severe and rare infections,” he said. “This makes it imperative for clinicians to be alert to the possibility of severe or rare infections in patients with psoriasis, especially those with severe psoriasis, so that early intervention can be initiated.”

As for additional research, “as an immunologist and dermatologist, I cannot help but think about the possible role the genetic and cytokine pathways involved in psoriasis may be playing in modulating the immune system and/or microbiome, and whether this contributes to a higher risk of infections,” Dr. Robles said. “Just as it was discovered that patients with atopic dermatitis have decreased levels of antimicrobial peptides in their skin, making them susceptible to recurrent bacterial skin infections, we may find that the genetic and immunological changes associated with psoriasis may independently contribute to infection susceptibility,” he noted. “More basic immunology and virology research may one day shed light on this observation.”

The study was supported by Novartis. Lead author Dr. Loft disclosed serving as a speaker for Eli Lilly and Janssen Cilag, other authors disclosed relationships with multiple companies including Novartis, and two authors are Novartis employees. Dr. Robles had no relevant financial disclosures.

Regardless of the severity of their initial illness, 89% of people who were hospitalized with COVID-19 had returned to their original work 2 years later, a new study shows.

The burden of persistent COVID-19 symptoms appeared to improve over time, but a higher percentage of former patients reported poor health, compared with the general population. This suggests that some patients need more time to completely recover from COVID-19, wrote the authors of the new study, which was published in The Lancet Respiratory Medicine. Previous research has shown that the health effects of COVID-19 last for up to a year, but data from longer-term studies are limited, said Lixue Huang, MD, of Capital Medical University, Beijing, one of the study authors, and colleagues.

Methods and results

In the new study, the researchers reviewed data from 1,192 adult patients who were discharged from the hospital after surviving COVID-19 between Jan. 7, 2020, and May 29, 2020. The researchers measured the participants’ health outcomes at 6 months, 12 months, and 2 years after their onset of symptoms. A community-based dataset of 3,383 adults with no history of COVID-19 served as controls to measure the recovery of the COVID-19 patients. The median age of the patients at the time of hospital discharge was 57 years, and 46% were women. The median follow-up time after the onset of symptoms was 185 days, 349 days, and 685 days for the 6-month, 12-month, and 2-year visits, respectively. The researchers measured health outcomes using a 6-min walking distance (6MWD) test, laboratory tests, and questionnaires about symptoms, mental health, health-related quality of life, returning to work, and health care use since leaving the hospital.

Overall, the proportion of COVID-19 survivors with at least one symptom decreased from 68% at 6 months to 55% at 2 years (P < .0001). The most frequent symptoms were fatigue and muscle weakness, reported by approximately one-third of the patients (31%); sleep problems also were reported by 31% of the patients.

The proportion of individuals with poor results on the 6MWD decreased continuously over time, not only in COVID-19 survivors overall, but also in three subgroups of varying initial disease severity. Of the 494 survivors who reported working before becoming ill, 438 (89%) had returned to their original jobs 2 years later. The most common reasons for not returning to work were decreased physical function, unwillingness to return, and unemployment, the researchers noted.

However, at 2 years, COVID-19 survivors reported more pain and discomfort, as well as more anxiety and depression, compared with the controls (23% vs. 5% and 12% vs. 5%, respectively).

In addition, significantly more survivors who needed high levels of respiratory support while hospitalized had lung diffusion impairment (65%), reduced residual volume (62%), and total lung capacity (39%), compared with matched controls (36%, 20%, and 6%, respectively) at 2 years.

Long-COVID concerns

Approximately half of the survivors had symptoms of long COVID at 2 years. These individuals were more likely to report pain or discomfort or anxiety or depression, as well as mobility problems, compared to survivors without long COVID. Participants with long-COVID symptoms were more than twice as likely to have an outpatient clinic visit (odds ratio, 2.82), and not quite twice as likely to be rehospitalized (OR, 1.64).

“We found that [health-related quality of life], exercise capacity, and mental health continued to improve throughout the 2 years regardless of initial disease severity, but about half still had symptomatic sequelae at 2 years,” the researchers wrote in their paper.

Findings can inform doctor-patient discussions

“We are increasingly recognizing that the health effects of COVID-19 may persist beyond acute illness, therefore this is a timely study to assess the long-term impact of COVID-19 with a long follow-up period,” said Suman Pal, MD, an internal medicine physician at the University of New Mexico, Albuquerque, in an interview.

The findings are consistent with the existing literature, said Dr. Pal, who was not involved in the study.  The data from the study “can help clinicians have discussions regarding expected recovery and long-term prognosis for patients with COVID-19,” he noted.

What patients should know is that “studies such as this can help COVID-19 survivors understand and monitor persistent symptoms they may experience, and bring them to the attention of their clinicians,” said Dr. Pal.

However, “As a single-center study with high attrition of subjects during the study period, the findings may not be generalizable,” Dr. Pal emphasized. “Larger-scale studies and patient registries distributed over different geographical areas and time periods will help obtain a better understanding of the nature and prevalence of long COVID,” he said.

The study findings were limited by several factors, including the lack of formerly hospitalized controls with respiratory infections other than COVID-19 to determine which outcomes are COVID-19 specific, the researchers noted. Other limitations included the use of data from only patients at a single center, and from the early stages of the pandemic, as well as the use of self-reports for comorbidities and health outcomes, they said.

However, the results represent the longest-known published longitudinal follow-up of patients who recovered from acute COVID-19, the researchers emphasized. Study strengths included the large sample size, longitudinal design, and long-term follow-up with non-COVID controls to determine outcomes. The researchers noted their plans to conduct annual follow-ups in the current study population. They added that more research is needed to explore rehabilitation programs to promote recovery for COVID-19 survivors and to reduce the effects of long COVID.

The study was supported by the Chinese Academy of Medical Sciences, National Natural Science Foundation of China, National Key Research and Development Program of China, National Administration of Traditional Chinese Medicine, Major Projects of National Science and Technology on New Drug Creation and Development of Pulmonary Tuberculosis, China Evergrande Group, Jack Ma Foundation, Sino Biopharmaceutical, Ping An Insurance (Group), and New Sunshine Charity Foundation. The researchers and Dr. Pal had no financial conflicts to disclose.

The researchers noted their plans to conduct annual follow-ups in the current study population. They added that more research is needed to explore rehabilitation programs to promote recovery for COVID-19 survivors and to reduce the effects of long COVID.

After hospitalization, COVID-19 patients 9 hours per day of sedentary time at 3-6 months after discharge, according to data from 37 individuals.

COVID-19 patients experience a wide range of clinical manifestations, and roughly half of those who were hospitalized for COVID-19 report persisting symptoms both physical and mental up to a year after discharge, Bram van Bakel, MD, of Radboud University Medical Center, Nijmegen, the Netherlands, said in a presentation at the presentation at the annual congress of the European Association of Preventive Cardiology.

However, data on physical activity patterns and the impact on recovery after postinfection hospital discharge are limited, he said. Dr. van Bakel and colleagues aimed to assess physical activity, sedentary behavior, and sleep duration in COVID-19 patients at 3-6 months after hospital discharge to explore the association with patient characteristics, disease severity and cardiac dysfunction.

“We hypothesized that COVID-19 survivors will demonstrate low volumes of physical activity and a high sedentary time, especially those with a more severe disease course,” such as longer hospital duration and admission to intensive care, cardiac dysfunction, and persistent symptoms at 3-6 months post discharge, he said.

Dr. van Bakel and colleagues enrolled 37 adult patients in a cross-sectional cohort study. They objectively assessed physical activity, sedentary behavior, and sleep duration for 24 hrs/day during 8 subsequent days in COVID-19 survivors at 3-6 months post hospitalization. The average age of the patients was 60 years, 78% were male, and the average assessment time was 125 days after hospital discharge.

The researchers compared activity patterns based on patient and disease characteristics, cardiac biomarker release during hospitalization, abnormal transthoracic echocardiogram regarding left and right ventricular function and volumes at 3-6 months of follow-up, and the persistence of symptoms after discharge.

Overall, patients spent a median of 4.2 hours per day in light-intensity physical activity, and 1 hour per day in moderate to vigorous physical activity. The overall median time spent sitting was 9.8 hours per day; this was accumulated in approximately 6 prolonged sitting periods of 30 minutes or more and 41.1 short sitting periods of less than 30 minutes.

The median sleep duration was 9.8 hours per day; sleep duration was significantly higher in women, compared with men (9.2 vs. 8.5 hours/day; P = .03), and in patients with persistent symptoms, compared with those without persistent symptoms (9.1 hrs/day vs. 8.3 hrs/day; P = .02). No other differences in activity or sitting patterns appeared among subgroups. Sedentary time of 10 hours or more per day overall puts individuals at increased risk for detrimental health effects, Dr. van Bakel said.

The study findings were limited by the small sample and cross-sectional design, he noted.

However, the results suggest that COVID-19 patients spent most of their time sedentary within the first 3-6 months after hospital discharge. The similar activity patterns across subgroups support a uniform approach to rehabilitation for these patients to target persisting symptoms and prevent long-term health consequences, said Dr. van Bakel. Further studies are warranted in a larger cohort with a prospective design and longitudinal follow-up.

The current study “highlights the need for ongoing rehabilitation in severe COVID-19 survivors after hospitalization to restore premorbid function and endurance,” Alba Miranda Azola, MD, of Johns Hopkins University, Baltimore, said in an interview.

“The findings regarding inactivity are not surprising,” said Dr. Azola. “Immobility during hospitalization results in muscle atrophy and marked decreased endurance. The need for prolonged use of sedation and paralytics during intensive care stays of severe COVID-19 patients is associated with critical illness myopathy. Also, many patients continue to experience hypoxia and dyspnea on exertion for several months after leaving the hospital. The functional impairments and limited activity tolerance often preclude patients from engaging on outpatient rehabilitation programs.

“I do think it surprising that the level of inactivity observed was independent of disease severity and patient factors, but it definitely speaks to the importance of establishing post hospitalization follow-up care that focuses on restoring function and mobility,” Dr. Azola noted.

The study findings may have long-term clinical implications, as COVID-19 survivors who experience functional decline that limits activity and who continue to lead a sedentary lifestyle may be at increased risk for health issues such as heart disease and type 2 diabetes, Dr. Azola said. 

Rigorous research is needed to study the functional and health impact of rehabilitation interventions during and after hospitalization, she emphasized. “Additionally, studies are needed on innovative rehabilitation interventions that improve accessibility to services to patients.”

Reduced exercise capacity and peak ventilation were significant predictors of early mortality in adults with chronic obstructive pulmonary disease, based on data from 126 individuals.

Cardiopulmonary exercise testing (CPET) is a common assessment for cardiorespiratory disease patients, but its role as a predictor of clinically relevant outcomes in chronic obstructive pulmonary disease (COPD) has not been investigated, and data on changes in exercise capacity over time in COPD patients are limited, wrote Cassia da Luz Goulart, MD, of the Federal University of São Carlos, Brazil, and colleagues.

The researchers hypothesized that CPET threshold values could be used as predictors of mortality in COPD.

In a prospective study published in Respiratory Medicine, the researchers identified 126 adults with COPD who were followed for 42 months. At study entry, each patient completed a clinical evaluation, followed by a pulmonary function test and CPET. The average age of the patients was 65 years, and 73% were men. All patients were on optimal medical management for COPD.

The researchers recorded data on peak oxygen consumption (VO₂, mL/min), VCO₂ (mL/min), minute ventilation (VE, L/min), the oxygen uptake efficiency slope (OUES), and ventilatory efficiency (the VE/VCO₂ slope).

The participants performed CPET on a cycle ergometer, with breath-by-breath analysis measured throughout the test using a computer-based system.

A total of 48 patients (38%) died during the 42-month follow-up period. Overall, the significant predictors of mortality were VE/VCO₂ slope of 30 or higher, peak VE of 25.7 L/min, and peak VO₂ ≤ 13.8 mLO₂ kg^–1 min^–1 were strong predictors of mortality in COPD patients in a Cox regression analysis.

When comparing the 78 survivors to the 48 nonsurvivors, the researchers found that the nonsurvivors were significantly more likely to be women, with worse lung function, inspiratory muscle weakness, and poorer CPET responses (P < .050 for all).

“The VE peak response is directly related to the FEV₁ in COPD patients, factors such as dyspnea and increased leg discomfort negatively impact the VE response during exercise,” the researchers wrote in their discussion of the findings. In this context, our results may hold clinical utility in refining the prognostic accuracy when a patient with COPD has a VE peak ≤ 25.7 L/min,” they explained.

The study findings were limited by the inability to assess complete pulmonary function in the COPD patients, and the assessment only of three CPET measures, the researchers noted.

However, the results support the use of CPET as a clinical assessment tool for COPD patients, they said. “Moreover, therapeutic approaches, such as cardiopulmonary rehabilitation, may consider focusing on improving these metabolic and ventilatory markers as an indicator of clinical improvement and prognosis in patients with COPD,” they added.

Bronchoscopic lung volume reduction significantly increased survival in patients with severe chronic obstructive pulmonary disease, based on data from more than 1,400 individuals.

Previous studies have shown that patients with severe chronic obstructive pulmonary disease (COPD) can benefit from treatment with bronchoscopic lung volume reduction (BLVR) involving lung volume reduction coils or endobronchial valves (EBVs) in terms of improved pulmonary function, lung volume, exercise capacity, and quality of life.

However, data on the impact of the procedure on patient survival are limited, and most previous studies have been small, wrote Jorine E. Hartman, MD, of the University of Groningen, the Netherlands, and colleagues.

In a study published in Respiratory Medicine, the researchers reviewed data from 1,471 patients with severe COPD who had consultations for BLVR at a single center between June 2006 and July 2019. Of these, 483 (33%) underwent a BLVR treatment.

The follow-up period ranged from 633 days to 5,401 days. During this time, 531 patients died (35%); 165 of these (34%) were in the BLVR group.

Overall, the median survival of BLVR patients was significantly longer, compared with those who did not have the procedure, for a difference of approximately 1.7 years (3,133 days vs. 2,503 days, P < .001). No significant differences in survival were noted in BLVR patients treated with coils or EBVs.

The average age of the study population at baseline was 61 years, and 63% were women. Overall, patients treated with BLVR were more likely to be younger and female, with fewer COPD exacerbations but worse pulmonary function, as well as lower body mass index and more evidence of emphysema than the untreated patients, the researchers noted. Patients treated with BLVR also were more likely than untreated patients to have a history of myocardial infarction, percutaneous coronary intervention, or stroke.

However, BLVR was a significant independent predictor of survival after controlling for multiple variables, including age, sex, and disease severity, the researchers noted.

The current study supports existing literature on the value of BLVR for severe COPD but stands out from previous studies by comparing patients who underwent BLVR with those who did not, the researchers noted in their discussion of the findings.

The study findings were limited by several factors, including the fact that the non-treated patients were not eligible for treatment for various reasons that might have impacted survival, the researchers noted. Another limitation was the lack of data on cause of death and other medical events and treatments during the follow-up period, they said.

However, the results were strengthened by the large sample size and long-term follow-up and suggest that “reducing lung volume in patients with COPD and severe hyperinflation and reduced life expectancy may lead to a survival benefit,” they concluded.

The study received no outside funding. Dr. Hartman had no financial conflicts to disclose.

Higher industriousness was associated with a 25% reduced risk of concurrent motoric cognitive risk syndrome (MCR), based on data from approximately 6,000 individuals.

Previous research supports an association between conscientiousness and a lower risk of MCR, a form of predementia that involves slow gait speed and cognitive complaints, wrote Yannick Stephan, PhD, of the University of Montpellier (France), and colleagues. However, the specific facets of conscientiousness that impact MCR have not been examined.

In a study published in the Journal of Psychiatric Research, the authors reviewed data from 6,001 dementia-free adults aged 65-99 years who were enrolled in the Health and Retirement Study, a nationally representative longitudinal study of adults aged 50 years and older in the United States.

Baseline data were collected between 2008 and 2010, and participants were assessed for MCR at follow-up points during 2012-2014 and 2016-2018. Six facets of conscientiousness were assessed using a 24-item scale that has been used in previous studies. The six facets were industriousness, self-control, order, traditionalism, virtue, and responsibility. The researchers controlled for variables including demographic factors, cognition, physical activity, disease burden, depressive symptoms, and body mass index.

Overall, increased industriousness was significantly associated with a lower likelihood of concurrent MCR (odds ratio, 0.75) and a reduced risk of incident MCR (hazard ratio, 0.63,; P < .001 for both).

The conscientiousness facets of order, self-control, and responsibility also were associated with a lower likelihood of both concurrent and incident MCR, with ORs ranging from 0.82-0.88 for concurrent and HRs ranging from 0.72-0.82 for incident.

Traditionalism and virtue were significantly associated with a lower risk of incident MCR, but not concurrent MCR (HR, 0.84; P < .01 for both).

The mechanism of action for the association may be explained by several cognitive, health-related, behavioral, and psychological pathways, the researchers wrote. With regard to industriousness, the relationship could be partly explained by cognition, physical activity, disease burden, BMI, and depressive symptoms. However, industriousness also has been associated with a reduced risk of systemic inflammation, which may in turn reduce MCR risk. Also, data suggest that industriousness and MCR share a common genetic cause.

The study findings were limited by several factors including the observational design and the positive selection effect from patients with complete follow-up data, as these patients likely have higher levels of order, industriousness, and responsibility, the researchers noted. However, the results support those from previous studies and were strengthened by the large sample and examination of six facets of conscientiousness.

“This study thus provides a more detailed understanding of the specific components of conscientiousness that are associated with risk of MCR among older adults,” and the facets could be targeted in interventions to reduce both MCR and dementia, they concluded.

The Health and Retirement Study is supported by the National Institute on Aging and conducted by the University of Michigan. The current study was supported in part by the National Institutes of Health. The researchers had no financial conflicts to disclose.

Higher industriousness was associated with a 25% reduced risk of concurrent motoric cognitive risk syndrome (MCR), based on data from approximately 6,000 individuals.

Previous research supports an association between conscientiousness and a lower risk of MCR, a form of predementia that involves slow gait speed and cognitive complaints, wrote Yannick Stephan, PhD, of the University of Montpellier (France), and colleagues. However, the specific facets of conscientiousness that impact MCR have not been examined.

In a study published in the Journal of Psychiatric Research, the authors reviewed data from 6,001 dementia-free adults aged 65-99 years who were enrolled in the Health and Retirement Study, a nationally representative longitudinal study of adults aged 50 years and older in the United States.

Baseline data were collected between 2008 and 2010, and participants were assessed for MCR at follow-up points during 2012-2014 and 2016-2018. Six facets of conscientiousness were assessed using a 24-item scale that has been used in previous studies. The six facets were industriousness, self-control, order, traditionalism, virtue, and responsibility. The researchers controlled for variables including demographic factors, cognition, physical activity, disease burden, depressive symptoms, and body mass index.

Overall, increased industriousness was significantly associated with a lower likelihood of concurrent MCR (odds ratio, 0.75) and a reduced risk of incident MCR (hazard ratio, 0.63,; P < .001 for both).

The conscientiousness facets of order, self-control, and responsibility also were associated with a lower likelihood of both concurrent and incident MCR, with ORs ranging from 0.82-0.88 for concurrent and HRs ranging from 0.72-0.82 for incident.

Traditionalism and virtue were significantly associated with a lower risk of incident MCR, but not concurrent MCR (HR, 0.84; P < .01 for both).

The mechanism of action for the association may be explained by several cognitive, health-related, behavioral, and psychological pathways, the researchers wrote. With regard to industriousness, the relationship could be partly explained by cognition, physical activity, disease burden, BMI, and depressive symptoms. However, industriousness also has been associated with a reduced risk of systemic inflammation, which may in turn reduce MCR risk. Also, data suggest that industriousness and MCR share a common genetic cause.

Nearly three-quarters of clinicians reported screening patients for hypertensive disorders of pregnancy, but only one-quarter comprehensively identified cardiovascular risk, based on survey data from approximately 1,500 clinicians in the United States.

Rates of hypertensive disorders of pregnancy have been on the rise in the United States for the past decade, and women with a history of these disorders require cardiovascular risk monitoring during the postpartum period and beyond, wrote Nicole D. Ford, PhD, of the Centers for Disease Control and Prevention, Atlanta, and colleagues. Specifically, the American College of Obstetricians and Gynecologists recommends cardiovascular risk evaluation and lifestyle modification for these individuals, the researchers said.

The most effective management of women with a history of hypertensive disorders of pregnancy will likely involve a team effort by primary care, ob.gyns., and cardiologists, but data on clinician screening and referrals are limited, they added.

In a study published in Obstetrics & Gynecology, the researchers reviewed data from a cross-sectional, web-based survey of clinicians practicing in the United States (Fall DocStyles 2020). The study population of 1,502 respondents with complete surveys included 1,000 primary care physicians, 251 ob.gyns., and 251 nurse practitioners or physician assistants. Approximately 60% of the respondents were male, and approximately 65% had been in practice for at least 10 years.

Overall, 73.6% of clinicians reported screening patients for a history of hypertensive disorders of pregnancy. The screening rates were highest among ob.gyns. (94.8%).

However, although 93.9% of clinicians overall correctly identified at least one potential risk associated with hypertensive disorders of pregnancy, only 24.8% correctly identified all cardiovascular risks associated with hypertensive disorders of pregnancy listed in the survey, the researchers noted.

Screening rates ranged from 49% to 91% for pregnant women, 34%-75% for postpartum women, 26%-61% for nonpregnant reproductive-age women, 20%-45% for perimenopausal or menopausal women, and 1%-4% for others outside of these categories.

The most often–cited barriers to referral were lack of patient follow-through (51.5%) and patient refusal (33.6%). To improve and facilitate referrals, respondents’ most frequent resource request was for more referral options (42.9%), followed by patient education materials (36.2%), and professional guidelines (34.1%).

In a multivariate analysis, primary care physicians were more than five times as likely to report not screening patients for hypertensive disorders of pregnancy (adjusted prevalence ratio, 5.54); nurse practitioners and physician assistants were more than seven times as likely (adjusted prevalence ratio, 7.42).

The researchers also found that clinicians who saw fewer than 80 patients per week were almost twice as likely not to screen for hypertensive disorders of pregnancy than those who saw 110 or more patients per week (adjusted prevalence ratio, 1.81).

“Beyond the immediate postpartum period, there is a lack of clear guidance on CVD [cardiovascular disease] evaluation and ongoing monitoring in women with history of hypertensive disorders of pregnancy,” the researchers wrote in their discussion. “Recognizing hypertensive disorders of pregnancy as a risk factor for CVD may allow clinicians to identify women requiring early evaluation and intervention,” they said.

The study findings were limited by several factors including potentially biased estimates of screening practices, and the potential for selection bias because of the convenience sample used to recruit survey participants, the researchers noted.

However, the results were strengthened by the inclusion of data from several clinician types and the relatively large sample size, and are consistent with those of previous studies, they said. Based on the findings, addressing barriers at both the patient and clinician level and increasing both patient and clinician education about the long-term risks of hypertensive disorders of pregnancy might increase cardiovascular screening and subsequent referrals, they concluded.
 

More education, improved screening tools needed

“Unfortunately, most CVD risk stratification scores such as the Framingham score do not include pregnancy complications, despite excellent evidence that pregnancy complications increase risk of CVD,” said Catherine M. Albright, MD, MS, of the University of Washington, Seattle, in an interview. “This is likely because these scores were developed primarily to screen for CVD risk in men. Given the rising incidence of hypertensive disorders of pregnancy and the clear evidence that this is a risk factor for future CVD, more studies like this one are needed in order to help guide patient and provider education,” said Dr. Albright, who was not involved in the study.

“It is generally well reported within the ob.gyn. literature about the increased lifetime CVD risk related to hypertensive disorders of pregnancy and we, as ob.gyns., always ask about pregnancy history because of our specialty, which gives us the opportunity to counsel about future risks,” she said.

“Women’s health [including during pregnancy] has been undervalued and underresearched for a long time,” with limited focus on pregnancy-related issues until recently, Dr. Albright noted. “This is clear in the attitudes and education of the primary care providers in this study,” she said.

A major barrier to screening in clinical practice has been that the standard screening guidelines for CVD (for example, those published by the United States Preventive Services Taskforce) have not included pregnancy history, said Dr. Albright. “Subsequently, these questions are not asked during routine annual visits,” she said. Ideally, “we should be able to leverage the electronic medical record to prompt providers to view a previously recorded pregnancy history or to ask about pregnancy history as a routine part of CVD risk assessment, and, of course, additional education outside of ob.gyn. and cardiology is needed,” she said.

The clinical takeaway from the current study is that “every annual visit with a person who has been pregnant is an opportunity to ask about and document pregnancy history,” Dr. Albright said. “After the completion of childbearing, many patients no longer see an ob.gyn., so other providers need to feel comfortable asking about and counseling about risks related to pregnancy complications,” she added.

“It is clear that adverse pregnancy outcomes pose lifetime health risks,” said Dr. Albright. “We will continue to look into the mechanisms of this through research. However, right now the additional research that is needed is to determine the optimal screening and follow-up for patients with a history of hypertensive disorders of pregnancy, as well as to examine how existing CVD-screening algorithms can be modified to include adverse pregnancy outcomes,” she emphasized.

The study received no outside funding. The researchers had no financial conflicts to disclose. Dr. Albright had no financial conflicts to disclose.

Intravenous steroids were less effective in ulcerative colitis patients with older-onset disease, compared with younger-onset patients, according to data from nearly 500 individuals.

A combination of rising ulcerative colitis rates and an aging population has driven an increase in older-onset UC worldwide, Shinji Okabayashi, MD, of Kyoto University, and colleagues wrote in a study published in Alimentary Pharmacology & Therapeutics.

Data on differences in disease history between younger- and older-onset cases have been inconsistent, but one meta-analysis suggested a higher rate of surgery in older-onset cases, the authors of the current study wrote. “The higher risk of surgery may be due to the difference in effectiveness of intravenous steroid treatment, which is one of the important treatment options to avoid surgery for a severe course of UC,” but data on the effectiveness of IV steroids for older-onset UC are lacking.

The researchers reviewed data from 467 adults with ulcerative colitis at 27 centers in Japan. The participants were hospitalized and received their initial intravenous steroids between April 2014 and July 2019. The treatment was a daily dose of 40 mg or more of IV prednisolone or its equivalent, with dosing according to current guidelines. The primary outcome was clinical remission after 30 days.

The study population included 83 patients with older-onset UC and 384 with younger-onset UC. No cutoff currently exists to classify UC by age; the researchers defined younger onset as patients diagnosed at younger than 60 years and older onset as those diagnosed at age 60 years and older. The median age of onset was 32 years in the younger-onset patients and 68 in the older-onset group.

Overall, 51.8% of older-onset patients and 65.6% of younger-onset patients had clinical remission at 30 days (adjusted risk ratio, 0.74; P = .009). The incidence of colectomy at 30 days was significantly higher in older-onset patients, compared with younger-onset patients (15.7% vs. 1.8%; P < .001).

The researchers also assessed risk of surgery and adverse events at 90 days as secondary outcomes. The risk of surgery was significantly higher in older-onset patients compared with younger-onset patients (20.5% vs. 3.1%; ARR, 8.92) as was the risk of adverse events (25.3% vs. 9.1%, ARR, 2.19). A total of four deaths occurred during the study period, all in older-onset patients.

In addition, the researchers found that clinical remission rates at 30 days in older patients with younger-onset UC was similar to that of younger patients with younger-onset UC.

Potential contributors to the lower effectiveness of intravenous steroids in older-onset UC include genetic susceptibility, gut microbiota, and environmental factors, the researchers noted. The dysregulated immune response in older-onset UC also might play a role in limiting the effectiveness of intravenous steroids in these patients.

The study findings were limited by several factors including the lack of data on genetic susceptibility, environmental factors, and gut microbiota, as well as the inclusion only of patients with moderate to severe disease, which might have contributed to the higher risk of surgery in older patients, the researchers said. Other potential limitations include the potential confounders of concomitant drugs and nutritional status, and the use of symptom-based scoring to determine clinical remission.

However, the overall results reflect data from a recent meta-analysis, and the current study “clearly suggests that one of the reasons for the poor prognosis in patients with older-onset UC is the lower effectiveness of intravenous steroid treatment, which is one of the important treatment options for a severe course of UC,” the researchers wrote.

“Further research is warranted to establish the optimal treatment strategies for moderate to severe older-onset UC,” they concluded.
 

Findings have value for high-risk patients

The study is of interest to clinicians in practice, Hamed Khalili, MD, of Massachusetts General Hospital, Boston, said in an interview. “The findings are largely consistent with prior studies that have shown older-onset IBD patients have higher risk of surgery,” said Dr. Khalili, who was not involved with the study.

“This study focuses on a smaller subset of patients with IBD who present with acute severe UC,” Dr. Khalili noted. “Since this is a higher-risk patient population, the findings that older-onset UC is associated with lower response to intravenous steroids could have direct clinical implications.”

The study was supported by the Japanese Society for Inflammatory Bowel Disease. The researchers had no relevant financial conflicts to disclose. Dr. Khalili had no financial conflicts to disclose.

A combination of rising ulcerative colitis rates and an aging population has driven an increase in older-onset UC worldwide, Shinji Okabayashi, MD, of Kyoto University, and colleagues wrote in a study published in Alimentary Pharmacology & Therapeutics.

Data on differences in disease history between younger- and older-onset cases have been inconsistent, but one meta-analysis suggested a higher rate of surgery in older-onset cases, the authors of the current study wrote. “The higher risk of surgery may be due to the difference in effectiveness of intravenous steroid treatment, which is one of the important treatment options to avoid surgery for a severe course of UC,” but data on the effectiveness of IV steroids for older-onset UC are lacking.

The researchers reviewed data from 467 adults with ulcerative colitis at 27 centers in Japan. The participants were hospitalized and received their initial intravenous steroids between April 2014 and July 2019. The treatment was a daily dose of 40 mg or more of IV prednisolone or its equivalent, with dosing according to current guidelines. The primary outcome was clinical remission after 30 days.

The study population included 83 patients with older-onset UC and 384 with younger-onset UC. No cutoff currently exists to classify UC by age; the researchers defined younger onset as patients diagnosed at younger than 60 years and older onset as those diagnosed at age 60 years and older. The median age of onset was 32 years in the younger-onset patients and 68 in the older-onset group.

Overall, 51.8% of older-onset patients and 65.6% of younger-onset patients had clinical remission at 30 days (adjusted risk ratio, 0.74; P = .009). The incidence of colectomy at 30 days was significantly higher in older-onset patients, compared with younger-onset patients (15.7% vs. 1.8%; P < .001).

The researchers also assessed risk of surgery and adverse events at 90 days as secondary outcomes. The risk of surgery was significantly higher in older-onset patients compared with younger-onset patients (20.5% vs. 3.1%; ARR, 8.92) as was the risk of adverse events (25.3% vs. 9.1%, ARR, 2.19). A total of four deaths occurred during the study period, all in older-onset patients.

In addition, the researchers found that clinical remission rates at 30 days in older patients with younger-onset UC was similar to that of younger patients with younger-onset UC.

Potential contributors to the lower effectiveness of intravenous steroids in older-onset UC include genetic susceptibility, gut microbiota, and environmental factors, the researchers noted. The dysregulated immune response in older-onset UC also might play a role in limiting the effectiveness of intravenous steroids in these patients.

The study findings were limited by several factors including the lack of data on genetic susceptibility, environmental factors, and gut microbiota, as well as the inclusion only of patients with moderate to severe disease, which might have contributed to the higher risk of surgery in older patients, the researchers said. Other potential limitations include the potential confounders of concomitant drugs and nutritional status, and the use of symptom-based scoring to determine clinical remission.

However, the overall results reflect data from a recent meta-analysis, and the current study “clearly suggests that one of the reasons for the poor prognosis in patients with older-onset UC is the lower effectiveness of intravenous steroid treatment, which is one of the important treatment options for a severe course of UC,” the researchers wrote.

“Further research is warranted to establish the optimal treatment strategies for moderate to severe older-onset UC,” they concluded.
 

Findings have value for high-risk patients

The study is of interest to clinicians in practice, Hamed Khalili, MD, of Massachusetts General Hospital, Boston, said in an interview. “The findings are largely consistent with prior studies that have shown older-onset IBD patients have higher risk of surgery,” said Dr. Khalili, who was not involved with the study.

“This study focuses on a smaller subset of patients with IBD who present with acute severe UC,” Dr. Khalili noted. “Since this is a higher-risk patient population, the findings that older-onset UC is associated with lower response to intravenous steroids could have direct clinical implications.”

Consistently sleeping 7 hours per night was associated with optimal cognitive function and mental health for middle-aged adults, a new study found.

Sleep disturbances are common in older age, and previous studies have shown associations between too much or too little sleep and increased risk of cognitive decline, but the ideal amount of sleep for preserving mental health has not been well described, according to the authors of the new paper.

In the study published in Nature Aging, the team of researchers from China and the United Kingdom reviewed data from the UK Biobank, a national database of individuals in the United Kingdom that includes cognitive assessments, mental health questionnaires, and brain imaging data, as well as genetic information.

Sleep is important for physical and psychological health, and also serves a neuroprotective function by clearing waste products from the brain, lead author Yuzhu Li of Fudan University, Shanghai, China, and colleagues wrote.

The study population included 498,277 participants, aged 38-73 years, who completed touchscreen questionnaires about sleep duration between 2006 and 2010. The average age at baseline was 56.5 years, 54% were female, and the mean sleep duration was 7.15 hours.

The researchers also reviewed brain imaging data and genetic data from 39,692 participants in 2014 to examine the relationships between sleep duration and brain structure and between sleep duration and genetic risk. In addition, 156,884 participants completed an online follow-up mental health questionnaire in 2016-2017 to assess the longitudinal impact of sleep on mental health.

Both excessive and insufficient sleep was associated with impaired cognitive performance, evidenced by the U-shaped curve found by the researchers in their data analysis, which used quadratic associations.

Specific cognitive functions including pair matching, trail making, prospective memory, and reaction time were significantly impaired with too much or too little sleep, the researchers said. “This demonstrated the positive association of both insufficient and excessive sleep duration with inferior performance on cognitive tasks.”

When the researchers analyzed the association between sleep duration and mental health, sleep duration also showed a U-shaped association with symptoms of anxiety, depression, mental distress, mania, and self-harm, while well-being showed an inverted U-shape. All associations between sleep duration and mental health were statistically significant after controlling for confounding variables (P < .001).

On further analysis (using two-line tests), the researchers determined that consistent sleep duration of approximately 7 hours per night was optimal for cognitive performance and for good mental health.

The researchers also used neuroimaging data to examine the relationship between sleep duration and brain structure. Overall, greater changes were seen in the regions of the brain involved in cognitive processing and memory.

“The most significant cortical volumes nonlinearly associated with sleep duration included the precentral cortex, the superior frontal gyrus, the lateral orbitofrontal cortex, the pars orbitalis, the frontal pole, and the middle temporal cortex,” the researchers wrote (P < .05 for all).

The association between sleep duration and cognitive function diminished among individuals older than 65 years, compared with those aged approximately 40 years, which suggests that optimal sleep duration may be more beneficial in middle age, the researchers noted. However, no similar impact of age was seen for mental health. For brain structure, the nonlinear relationship between sleep duration and cortical volumes was greatest in those aged 44-59 years, and gradually flattened with older age.
 

Research supports sleep discussions with patients

“Primary care physicians can use this study in their discussions with middle-aged and older patients to recommend optimal sleep duration and measures to achieve this sleep target,” Noel Deep, MD, a general internist in group practice in Antigo, Wisc., who was not involved in the study, said in an interview.

“This study is important because it demonstrated that both inadequate and excessive sleep patterns were associated with cognitive and mental health changes,” said Dr. Deep. “It supported previous observations of cognitive decline and mental health disorders being linked to disturbed sleep. But this study was unique because it provides data supporting an optimal sleep duration of 7 hours and the ill effects of both insufficient and excessive sleep duration.

“The usual thought process has been to assume that older individuals may not require as much sleep as the younger individuals, but this study supports an optimal time duration of sleep of 7 hours that benefits the older individuals. It was also interesting to note the mental health effects caused by the inadequate and excessive sleep durations,” he added.

As for additional research, “I would like to look into the quality of the sleep, in addition to the duration of sleep,” said Dr. Deep. For example, whether the excessive sleep was caused by poor quality sleep or fragmented sleep leading to the structural and subsequent cognitive decline.
 

Study limitations

“The current study relied on self-reporting of the sleep duration and was not observed and recorded data,” Dr. Deep noted. “It would also be beneficial to not only rely on healthy volunteers reporting the sleep duration, but also obtain sleep data from individuals with known brain disorders.”

The study findings were limited by several other factors, including the use of total sleep duration only, without other measures of sleep hygiene, the researchers noted. More research is needed to investigate the mechanisms driving the association between too much and not enough sleep and poor mental health and cognitive function.

The study was supported by the National Key R&D Program of China, the Shanghai Municipal Science and Technology Major Project, the Shanghai Center for Brain Science and Brain-Inspired Technology, the 111 Project, the National Natural Sciences Foundation of China and the Shanghai Rising Star Program.

Approximately 7% of youth who chose gender identity social transition in early childhood had retransitioned 5 years later, based on data from 317 individuals.

“Increasing numbers of children are socially transitioning to live in line with their gender identity, rather than the gender assumed by their sex at birth – a process that typically involves changing a child’s pronouns, first name, hairstyle, and clothing,” wrote Kristina R. Olson, PhD, of Princeton (N.J.) University, and colleagues.

The question of whether early childhood social transitions will result in high rates of retransition continues to be a subject for debate, and long-term data on retransition rates and identity outcomes in children who transition are limited, they said.

To examine retransition in early-transitioning children, the researchers identified 317 binary socially transitioned transgender children to participate in a longitudinal study known as the Trans Youth Project (TYP) between July 2013 and December 2017. The study was published in Pediatrics. The mean age at baseline was 8 years. At study entry, participants had to have made a complete binary social transition, including changing their pronouns from those used at birth. During the 5-year follow-up period, children and parents were asked about use of puberty blockers and/or gender-affirming hormones. At study entry, 37 children had begun some type of puberty blockers. A total of 124 children initially socially transitioned before 6 years of age, and 193 initially socially transitioned at 6 years or older.

The study did not evaluate whether the participants met the DSM-5 criteria for gender dysphoria in childhood, the researchers noted. “Based on data collected at their initial visit, we do know that these participants showed signs of gender identification and gender-typed preferences commonly associated with their gender, not their sex assigned at birth,” they wrote.

Participants were classified as binary transgender, nonbinary, or cisgender based on their pronouns at follow-up. Binary transgender pronouns were associated with the other binary assigned sex, nonbinary pronouns were they/them or a mix of they/them and binary pronouns, and cisgender pronouns were those associated with assigned sex.

Overall, 7.3% of the participants had retransitioned at least once by 5 years after their initial binary social transition. The majority (94%) were living as binary transgender youth, including 1.3% who retransitioned to cisgender or nonbinary and then back to binary transgender during the follow-up period. A total of 2.5% were living as cisgender youth and 3.5% were living as nonbinary youth. These rates were similar across the initial population, as well as the 291 participants who continue to be in contact with the researchers, the 200 who had gone at least 5 years since their initial social transition, and the 280 participants who began the study before starting puberty blockers.

The researchers found no differences in retransition rates related to participant sex at birth. Rates of retransition were slightly higher among participants who made their initial social transition before 6 years of age, but these rates were low, the researchers noted.

The study findings were limited by several factors including the use of a volunteer community sample, with the potential for bias that may not generalize to the population at large, the researchers noted. Other limitations included the use of pronouns as the main criteria for retransition, and the classification of a change from binary transgender to nonbinary as a transition, they said. “Many nonbinary people consider themselves to be transgender,” they noted.

“If we had used a stricter criterion of retransition, more similar to the common use of terms like “detransition” or “desistence,” referring only to youth who are living as cisgender, then our retransition rate would have been lower (2.5%),” the researchers explained. Another limitation was the disproportionate number of trans girls, the researchers said. However, because no significant gender effect appeared in terms of retransition rates, “we do not predict any change in pattern of results if we had a different ratio of participants by sex at birth,” they said.

The researchers stated that they intend to follow the cohort through adolescence and into adulthood.

“As more youth are coming out and being supported in their transitions early in development, it is increasingly critical that clinicians understand the experiences of this cohort and not make assumptions about them as a function of older data from youth who lived under different circumstances,” the researchers emphasized. “Though we can never predict the exact gender trajectory of any child, these data suggest that many youth who identify as transgender early, and are supported through a social transition, will continue to identify as transgender 5 years after initial social transition.” They concluded that more research is needed to determine how best to support initial and later gender transitions in youth.
 

Study offers support for family discussions

“This study is important to help provide more data regarding the experiences of gender-diverse youth,” M. Brett Cooper, MD, of UT Southwestern Medical Center, Dallas, said in an interview. “The results of a study like this can be used by clinicians to help provide advice and guidance to parents and families as they support their children through their gender journey,” said Dr. Cooper, who was not involved in the study. The current study “also provides evidence to support that persistent, insistent, and consistent youth have an extremely low rate of retransition to a gender that aligns with their sex assigned at birth. This refutes suggestions by politicians and others that those who seek medical care have a high rate of regret or retransition,” Dr. Cooper emphasized.

“I was not surprised at all by their findings,” said Dr. Cooper. “These are very similar to what I have seen in my own panel of gender-diverse patients and what has been seen in other studies,” he noted.

The take-home message of the current study does not suggest any change in clinical practice, Dr. Cooper said. “Guidance already suggests supporting these youth on their gender journey and that for some youth, this may mean retransitioning to identify with their sex assigned at birth,” he explained.

The study was supported in part by grants to the researchers from the National Institutes of Health, the National Science Foundation, the Arcus Foundation, and the MacArthur Foundation. The researchers had no financial conflicts to disclose.

These rates were similar across the initial population, as well as the 291 participants who continue to be in contact with the researchers, the 200 who had gone at least 5 years since their initial social transition, and the 280 participants who began the study before starting puberty blockers.

The researchers found no differences in retransition rates related to participant sex at birth. Rates of retransition were slightly higher among participants who made their initial social transition before 6 years of age, but these rates were low, the researchers noted.

The study findings were limited by several factors including the use of a volunteer community sample, with the potential for bias that may not generalize to the population at large, the researchers noted. Other limitations included the use of pronouns as the main criteria for retransition, and the classification of a change from binary transgender to nonbinary as a transition, they said. “Many nonbinary people consider themselves to be transgender,” they noted.

“If we had used a stricter criterion of retransition, more similar to the common use of terms like “detransition” or “desistence,” referring only to youth who are living as cisgender, then our retransition rate would have been lower (2.5%),” the researchers explained. Another limitation was the disproportionate number of trans girls, the researchers said. However, because no significant gender effect appeared in terms of retransition rates, “we do not predict any change in pattern of results if we had a different ratio of participants by sex at birth,” they said.

The researchers stated that they intend to follow the cohort through adolescence and into adulthood.

“As more youth are coming out and being supported in their transitions early in development, it is increasingly critical that clinicians understand the experiences of this cohort and not make assumptions about them as a function of older data from youth who lived under different circumstances,” the researchers emphasized. “Though we can never predict the exact gender trajectory of any child, these data suggest that many youth who identify as transgender early, and are supported through a social transition, will continue to identify as transgender 5 years after initial social transition.” They concluded that more research is needed to determine how best to support initial and later gender transitions in youth.
 

Study offers support for family discussions

“This study is important to help provide more data regarding the experiences of gender-diverse youth,” M. Brett Cooper, MD, of UT Southwestern Medical Center, Dallas, said in an interview. “The results of a study like this can be used by clinicians to help provide advice and guidance to parents and families as they support their children through their gender journey,” said Dr. Cooper, who was not involved in the study. The current study “also provides evidence to support that persistent, insistent, and consistent youth have an extremely low rate of retransition to a gender that aligns with their sex assigned at birth. This refutes suggestions by politicians and others that those who seek medical care have a high rate of regret or retransition,” Dr. Cooper emphasized.

“I was not surprised at all by their findings,” said Dr. Cooper. “These are very similar to what I have seen in my own panel of gender-diverse patients and what has been seen in other studies,” he noted.

The take-home message of the current study does not suggest any change in clinical practice, Dr. Cooper said. “Guidance already suggests supporting these youth on their gender journey and that for some youth, this may mean retransitioning to identify with their sex assigned at birth,” he explained.

The study was supported in part by grants to the researchers from the National Institutes of Health, the National Science Foundation, the Arcus Foundation, and the MacArthur Foundation. The researchers had no financial conflicts to disclose.
