Classification of COPD exacerbation predicts prognosis
Adults with exacerbations of chronic obstructive pulmonary disease (ECOPD) whose condition was classified as severe using the Rome criteria had a higher risk of death at 1 year than those who were classified as having moderate or mild disease, as determined from data from more than 300 individuals.
Patients hospitalized with severe exacerbations of ECOPD are at increased risk for worse clinical outcomes and death, so early identification is important, Ernesto Crisafulli, MD, of the University of Verona (Italy) and Azienda Ospedaliera Universitaria Integrata of Verona, and colleagues wrote.
which grades ECOPD as mild, moderate, or severe on the basis of more objective and disease-related aspects. However, data on the clinical usefulness of the Rome criteria are limited.
In a study published in the journal Chest, the researchers retrospectively categorized 347 adults hospitalized with ECOPD using the Rome severity classifications of mild, moderate, and severe.
Classifications were made using baseline, clinical and microbiological factors, as well as gas analysis and laboratory variables. The researchers also reviewed data on the length of hospital stay and mortality (in-hospital and over a follow-up of 6 months to 3 years).
Approximately one-third of the patients (39%) were classified as having mild disease, 31% as having moderate disease, and 30% as having severe illness. Overall, hospital stay was significantly longer for the patients with severe disease, although in-hospital mortality was similar across all three groups.
Patients classified as having severe disease also had a worse prognosis at all follow-up time points, and severe classification was significantly associated with worse cumulative survival at 1 year and 3 years (Gehan-Breslow-Wilson test, P = .032 and P = .004, respectively).
In a multivariate analysis, the risk of death at 1 year was significantly higher among patients classified as severe or moderate (hazard ratio, 1.99 and 1.47, respectively), compared with those classified as mild.
Mortality risk also was higher among patients aged 80 years and older and among those requiring long-term oxygen therapy or with a history of ECOPD episodes, the researchers noted. Body mass index in the range of 25-29 kg/m2 was associated with lower risk.
The study was limited by several factors, including the replacement of dyspnea perception in the Rome classification with other objective measures, the researchers wrote. Other limitations include the retrospective design, small sample size, use of data from a single center, and lack of data on causes of mortality. Women were underrepresented in the study, and so additional research involving women is needed.
The results suggest that the Rome classification allows for the effective identification of patients with ECOPD who have a worse prognosis. The Rome classification may help guide disease management through targeted interventions and personalized care programs for this population, the researchers concluded.
The study received no outside funding. The researchers disclosed no relevant financial relationships.

Dural-puncture epidural drives faster conversion to cesarean anesthesia
DPE, while not new, has become more popular as an option for initiating labor analgesia, but data comparing DPE with standard epidural in conversion to surgical anesthesia for cesarean deliveries are limited, Nadir Sharawi, MD, of the University of Arkansas for Medical Sciences, Little Rock, and colleagues wrote.
DPE involves no injection of intrathecal drugs, and the potential advantages include easier translocation of epidural medications into the intrathecal space for improved analgesia, but the effects of DPE on the onset and reliability of surgical anesthesia remain unknown, they said.
In a study published in JAMA Network Open, the researchers randomized 70 women scheduled for cesarean delivery of singleton pregnancies to DPE and 70 to a standard epidural. The participants were aged 18 years and older, with a mean age of the 30.1 years; the study was conducted between April 2019 and October 2022 at a single center.
The primary outcome was the time to the loss of sharp sensation at T6, defined as “the start of epidural extension anesthesia (time zero on the stopwatch) to when the patient could no longer feel sharp sensation at T6 (assessed bilaterally at the midclavicular line),” the researchers wrote.
The onset time to surgical anesthesia was faster in the DPE group, compared with the standard group, with a median of 422 seconds versus 655 seconds.
A key secondary outcome was a composite measure of the quality of epidural anesthesia that included failure to achieve a T10 bilateral block preoperatively in the delivery room, failure to achieve a surgical block at T6 within 15 minutes of chloroprocaine administration, requirement for intraoperative analgesia, repeat neuraxial procedure, and conversion to general anesthesia. The composite rates of lower quality anesthesia were significantly less in the DPE group, compared with the standard group (15.7% vs. 36.3%; P = .007).
Additional secondary outcomes included maternal satisfaction and pain score during surgery, adverse events, opioid use in the first 24 hours, maternal vasopressor requirements, epidural block assessments, and neonatal outcomes. No significant differences in these outcomes were noted between the groups, and no instances of local anesthetic systemic toxicity or neurological complications were reported.
The findings were limited by several factors including the study population of women scheduled for cesarean delivery and not in labor, and the inability to detect less frequent complications such as post–dural-puncture headache and accidental dural puncture, the researchers noted.
In addition, the results may vary with the use of other combinations of local anesthetics and opioids. “Chloroprocaine was chosen in this study because of its ease of administration without the need for opioids and other additives along with the low risk of systemic toxic effects, which favors rapid administration for emergent cesarean delivery,” they wrote.
However, the results show an association between DPE within an hour of epidural extension for elective cesarean delivery and a faster onset of anesthesia, improved block quality, and a more favorable ratio of risks versus benefits, compared with the use of standard epidural, the researchers concluded.
No need for general anesthesia?
“There is controversy over whether the dural puncture epidural technique improves labor analgesia when compared to a standard epidural,” Dr. Shawari said in an interview. “However, there are limited data on whether the dural puncture epidural technique decreases the onset time to surgical anesthesia when compared to a standard epidural for cesarean delivery. This is important as a pre-existing epidural is commonly used to convert labor analgesia to surgical anesthesia in the setting of urgent cesarean delivery. A faster onset of epidural anesthesia could potentially avoid the need for general anesthesia in an emergency.”
The researchers were not surprised by the findings given their experience with performing dural puncture epidurals for labor analgesia, Dr. Shawari said. In those cases, DPE provided a faster onset when converting cesarean anesthesia, compared with a standard epidural.
The takeaway from the current study is that DPE also provided “a faster onset and improved quality of anesthesia when compared to standard epidural for elective cesarean delivery,” Dr. Shawari said. However, additional research is needed to confirm the findings for intrapartum cesarean delivery.
Progress in improving pain control
“Adequate pain control during cesarean delivery is incredibly important,” Catherine Albright, MD, a maternal-fetal medicine specialist at the University of Washington, Seattle, said in an interview. “Inadequate pain control leads to the need to provide additional intravenous medications or the need to be put under general anesthesia, which changes the birth experience and is more dangerous for the birthing person and the neonate.
“In my clinical experience, there are many times when patients do not have adequate pain control during a cesarean delivery,” said Dr. Albright, who was not involved in the current study. “I am pleased to see that there is research underway about how to best manage pain on labor and delivery, especially in the setting of conversion from labor anesthesia to cesarean anesthesia.”
The findings may have implications for clinical practice, said Dr. Albright. If the dural puncture epidural can improve cesarean anesthesia following an epidural during labor, rather than anesthesia provided for an elective cesarean), “then I believe it would reduce the number of patients who require additional pain medication, have a poor cesarean experience, and/or need to be put under general anesthesia.”
However, “as noted by the authors, additional research is needed to further determine possible risks and side effects from this technique, and also to ensure that it also works in the setting of labor, rather than for an elective cesarean,” Dr. Albright added.

Vasopressin may promote lower mortality in septic shock
according to a review of three recent studies.
“Patients with septic shock require vasoactive agents to restore adequate tissue perfusion,” writes Gretchen L. Sacha, PharmD, of the Cleveland Clinic and colleagues.
Vasopressin is an attractive alternative to norepinephrine because it avoids the adverse effects associated with catecholamines, the researchers say. Although vasopressin is the recommended second-line adjunct after norepinephrine for patients with septic shock, findings to guide its use are inconsistent and data on the timing are limited, they note.
In a review published in the journal CHEST, the researchers summarize the three large, randomized trials to date examining the use of norepinephrine and vasopressin in patients with septic shock.
In the Vasopressin in Septic Shock Trial (VASST), 382 patients with septic shock were randomized to open-label norepinephrine with blinded norepinephrine, and 382 were randomized to open-label norepinephrine with blinded adjunctive vasopressin.
After initiation of the study drug, patients randomized to vasopressin had significantly lower requirements for open-label norepinephrine (P < .001). Although no differences occurred in the primary outcome of 28-day mortality, 90-day mortality was lower in the vasopressin group.
In the Vasopressin vs Norepinephrine as Initial Therapy in Septic Shock (VANISH) trial, 204 patients with septic shock were randomized to norepinephrine and 204 to vasopressin as an initial vasoactive agent. Although no differences appeared between the groups for the two primary outcomes of 28-day mortality and days free of kidney failure, the vasopressin group had a lower frequency of the use of kidney replacement therapy (absolute difference –9.9% vs. –0.6%).
The VANISH study was limited by the fact that 85% of the patients were receiving norepinephrine when they were randomized; “therefore, this study is best described as evaluating catecholamine-adjunctive vasopressin,” the researchers say.
The third clinical trial, published only as an abstract, randomized 387 patients with septic shock who were already receiving low doses of norepinephrine to either norepinephrine with adjunctive vasopressin or norepinephrine alone. Rates of 28-day mortality were significantly lower in the vasopressin group (34.0% vs. 42.3%; P = .03).
Several meta-analyses involving multiple vasopressin receptor agonists have shown an association between reduced mortality and their use. In addition, recent observational studies have shown an association between lower mortality and the initiation of vasopressors at a lower norepinephrine-equivalent dose or lower lactate concentration.
As for clinical implications, the 2021 version of the Surviving Sepsis Campaign (SSC) guidelines included a meta-analysis of 10 randomized, controlled trials that showed improved mortality associated with vasopressin use. This version of the guidelines was the first to address the timing of vasopressin initiation.
Because of insufficient evidence, the guidance was worded as “in our practice, vasopressin is usually started when the dose of norepinephrine is in the range of 0.25-0.5 mcg/kg/min,” the researchers write. “Although this is not a recommendation by the SSC for a specific threshold of catecholamine dose where vasopressin should be initiated, this statement represents clinician interest and the need for further research on the topic,” they note.
“Future studies of vasopressin should focus on the timing of its initiation at various clinical thresholds and patient selection for receipt of vasopressin,” they conclude.
The study was supported by the National Institutes of Health, National Institute of General Medical Sciences. Dr. Sacha has disclosed consulting for Wolters Kluwer.

Because of insufficient evidence, the guidance was worded as “in our practice, vasopressin is usually started when the dose of norepinephrine is in the range of 0.25-0.5 mcg/kg/min,” the researchers write. “Although this is not a recommendation by the SSC for a specific threshold of catecholamine dose where vasopressin should be initiated, this statement represents clinician interest and the need for further research on the topic,” they note.
“Future studies of vasopressin should focus on the timing of its initiation at various clinical thresholds and patient selection for receipt of vasopressin,” they conclude.
The study was supported by the National Institutes of Health, National Institute of General Medical Sciences. Dr. Sacha has disclosed consulting for Wolters Kluwer.

Neutropenia affects clinical presentation of pulmonary mucormycosis
, based on data from 114 individuals.
Diagnosis of pulmonary mucormycosis (PM), an invasive and potentially life-threatening fungal infection, is often delayed because of its variable presentation, wrote Anne Coste, MD, of La Cavale Blanche Hospital and Brest (France) University Hospital, and colleagues.
Improved diagnostic tools including molecular identification and image-guided lung biopsies are now available in many centers, but relations between underlying conditions, clinical presentations, and diagnostic methods have not been described, they said.
In a study published in the journal Chest, the researchers reviewed data from all cases of PM seen at six hospitals in France between 2008 and 2019. PM cases were based on European Organization for Research and Treatment of Cancer and the National Institute of Allergy and Infectious Diseases Mycoses Study Group (EORTC/MSG) criteria. Diabetes and trauma were included as additional host factors, and positive serum or tissue PCR (serum qPCR) were included as mycological evidence. Participants also underwent thoracic computed tomography (CT) scans.
The most common underlying conditions among the 114 patients were hematological malignancy (49%), allogeneic hematopoietic stem-cell transplantation (21%), and solid organ transplantation (17%).
Among the 40% of the cases that involved dissemination, the most common sites were the liver (48%), spleen (48%), brain (44%), and kidneys (37%).
A review of radiology findings showed consolidation in a majority of patients (58%), as well as pleural effusion (52%). Other findings included reversed halo sign (RHS, 26%), halo sign (24%), vascular abnormalities (26%), and cavity (23%).
Bronchoalveolar lavage (BAL) was present in 46 of 96 patients (50%), and transthoracic lung biopsy was used for diagnosis in 8 of 11 (73%) patients with previous negative BALs.
Seventy patients had neutropenia. Overall, patients with neutropenia were significantly more likely than were those without neutropenia to show an angioinvasive presentation that included both RHS and disease dissemination (P < .05).
In addition, serum qPCR was positive in 42 of 53 patients for whom data were available (79%). Serum qPCR was significantly more likely to be positive in neutropenic patients (91% vs. 62%, P = .02). Positive qPCR was associated with an early diagnosis (P = .03) and treatment onset (P = .01).
Possible reasons for the high rate of disseminated PM in the current study may be the large number of patients with pulmonary involvement, use of body CT data, and availability of autopsy results (for 11% of cases), the researchers wrote in their discussion.
Neutropenia and radiological findings influence disease presentation and contribution of diagnostic tools during PM. Serum qPCR is more contributive in neutropenic patients and BAL examination in nonneutropenic patients. Lung biopsies are highly contributive in case of non-contributive BAL.
The findings were limited by several factors including the retrospective design, the inability to calculate sensitivity and specificity of diagnostic methods, and lack of data on patients with COVID-19, the researchers noted. However, the results provide real-life information for clinicians in centers with current mycological platforms, they concluded.
The study received no outside funding. Dr. Coste had no financial conflicts to disclose.

Rheumatoid arthritis may raise risk for aortic stenosis
Adults with rheumatoid arthritis had a significantly higher risk than do those without RA for developing aortic stenosis (AS), according to a large national cohort of patients.
RA has been associated with an increased risk for ischemic cardiovascular disease, but the association of RA with the risk for AS remains unclear, Tate M. Johnson, MD, of VA Nebraska–Western Iowa Health Care System, Omaha, and colleagues wrote.
In a study published in JAMA Internal Medicine, the researchers identified 73,070 adults with RA and 639,268 matched control individuals without RA using data from Veterans Affairs and Centers for Medicare & Medicaid Services from 2000 to 2019.
The patients and control individuals were predominantly men (about 87%), and most were White (72.3% of patients and 61.7% of control individuals). The mean ages of the patients and control individuals were similar (63.0 vs. 61.9, respectively).
The main outcome of incident AS was defined as a composite of inpatient or outpatient AS diagnoses, surgical or transcatheter aortic valve intervention, or AS-related death.
Over a mean follow-up period of 7.9 years in patients with RA and 8.8 years in control individuals, the researchers found 16,109 composite AS outcomes over a period of 6,223,150 person-years, with 2,303 that occurred in patients with RA.
The multivariate model adjusted for race, ethnicity, smoking status, body mass index (BMI), rural versus urban residence, comorbidities, and health care use.
Overall, RA was associated with an increased risk for the composite AS outcome (hazard ratio, 1.66).
After adjusting for confounders, RA remained associated with an increased risk for composite AS diagnoses, aortic valve intervention, and AS-related death (adjusted HRs, 1.48, 1.34, and 1.26, respectively). Altogether, the incidence of composite AS events was 3.97 per 1,000 person-years in patients with RA versus 2.45 per 1,000 person-years in control individuals, with an absolute difference of 1.52 composite AS events per 1,000 person-years.
The results “emphasize that valvular heart disease may be an underrecognized contributor to the persistent CVD [cardiovascular disease]-related mortality gap in RA, particularly given the lack of improvement in AS-specific risk over time,” the researchers wrote.
Several traditional CVD risk factors (for example, smoking status, diabetes, and coronary artery disease) were not independently associated with AS onset in patients with RA. However, male sex, hypertension, stroke, and other noncoronary CVDs were associated with incident AS in the patients with RA, and increasing age and BMI were associated with stepwise increases in AS risk.
The findings were limited by several factors including the infrequency of AS-related events and consequent modest differences in absolute risk, the researchers noted. The predominantly male cohort may limit generalizability of results because RA is more common in women. Other limitations included the predominantly male population and possible misclassification of RA status.
Overall, the results demonstrate an increased risk for AS, AS-related intervention, and AS-related death in people with RA. More research is needed to examine AS and valvular heart disease as potential complications in this population, they concluded.
The study was supported by the Center of Excellence for Suicide Prevention, Joint Department of Veterans Affairs, and Department of Defense Mortality Data Repository National Death Index. Dr. Johnson disclosed grants from the Rheumatology Research Foundation during the conduct of the study but had no other financial conflicts to disclose. Other authors disclosed fees and honoraria from pharmaceutical companies outside the submitted work.

Exercise program boosted physical, but not mental, health in young children with overweight
A defined exercise program significantly improved cardiometabolic health and body composition in children with overweight and obesity, but no effect was seen on mental health, based on data from 92 children.
Childhood obesity is associated with negative health outcomes including type 2 diabetes, cardiovascular disease, and mental health disorders, and exercise is considered essential to treatment, wrote Jairo H. Migueles, PhD, of the University of Granada, Spain, and colleagues. However, the effect on children with obesity and overweight of an exercise program on physical and mental health, including within-individual changes, has not been well studied, they said.
In a study published in JAMA Network Open, the researchers reviewed data from 36 girls and 56 boys with overweight or obesity who were randomized to a 20-week exercise program with aerobic and resistance elements, or waitlisted to serve as controls. The participants ranged in age from 8 to 11 years with a mean age of 10 years. The data were collected between Nov. 1, 2014, and June 30, 2016, as part of a parallel-group randomized clinical trial. The exercise program consisted of three to five 90-minute exercise sessions per week for 20 weeks, and the control children continued their usual routines.
The main cardiometabolic outcomes measured in the study were divided into three categories: body composition, physical fitness, and traditional risk factors (waist circumference, blood lipid levels, glucose levels, insulin levels, and blood pressure).
A cardiometabolic risk score was defined by z score. The researchers also added cardiorespiratory fitness (CRF) to the cardiometabolic risk score. Mental health was assessed using composite standardized scores for psychological well-being and poor mental health.
After 20 weeks, cardiometabolic risk scores decreased by approximately 0.38 standard deviations in the exercise group compared with the control group. In addition, specific measures of cardiometabolic health improved significantly from baseline in the exercise group compared with control children for low-density lipoprotein (change of –7.00 mg/dL), body mass index (–5.9 kg/m2), fat mass index (−0.67), and visceral adipose tissue (31.44 g).
Cardiorespiratory fitness improved by 2.75 laps in the exercise group compared with control children. In addition, significantly more children in the exercise group showed meaningful changes (defined as individual changes of at least 0.2 SDs) compared with control children in measures of fat mass index (37 vs. 17, P < .001) and CRF performance (30 vs. 17, P = .03).
However, no significant effects appeared on mental health outcomes in exercisers, the researchers noted.
The reduction in cardiometabolic score was attributable mainly to improvements in cardiovascular fitness, blood lipid levels, and total and visceral adiposity, the researchers wrote in their discussion. The lack of changes in mental health measures may be a result of the healthy mental state of the children at the study outset, they said. “The null effect on mental health outcomes needs to be further investigated, including, among other things, whether the instruments are sensitive enough to detect changes and whether there is a ceiling effect in young children who might be mentally healthy overall,” they wrote.
The findings were limited by several factors, including the relatively small sample size and lack of blinding for some evaluators. However, the results show the potential of exercise programs to affect meaningful change and improve cardiometabolic health in overweight and obese children, although more research is needed to explore the effects of larger-scale and longer-lasting public health interventions combining exercise and other health behaviors such as diet, the researchers concluded.
Bottom line: Exercise works
The increasing rates of overweight and obesity in children in the United States have “significant downstream consequences that include increased risk of metabolic disease, including diabetes and hypertension, as well as increased rates of anxiety and depression,” Neil Skolnik, MD, professor of family and community medicine at the Sidney Kimmel Medical College of Thomas Jefferson University, Philadelphia, said in an interview.
Therefore, the effect of interventions such as exercise training on outcomes is important, he said.
The current study findings are “what you would hope for and expect – improvement in cardiometabolic parameters and fitness,” said Dr. Skolnik. “It was encouraging to see the effect of this relatively short duration of intervention has a clear positive effect on weight, BMI, and cardiometabolic parameters,” he said. “The real benefit, of course, comes from sustaining these habits over a long period of time.”
The lack of improvement in mental health is not surprising given the small study population “who did not have a high rate of mental health problems to begin with,” Dr. Skolnik added.
Barriers to promoting exercise programs for obese and overweight children in primary care are many, Dr. Skolnik said, including “having the motivation and funding to create programs like this so they are readily available to youth.”
However, the key message from the current study is simple and straightforward, according to Dr. Skolnik. “Exercise works! It works to improve fitness, cardiometabolic parameters, and weight control,” he said.
“There is always room for more research,” Dr. Skolnik added. The questions now are not about whether exercise benefits health; they are about figuring out how to implement the known benefits of exercise into daily living for all children, athletes and nonathletes alike, he said. “We need to find nonjudgmental ways to encourage exercise as a part of routine daily healthy living, up there with brushing teeth every day,” he emphasized.
The study was supported by grants from the Spanish Ministry of Economy and Competitiveness and El Fondo Europeo de Desarrollo Regional (FEDER) and by the MCIN (Ministerio de Ciencia e Innovación) / AEI (Agencia Estatal de Investigación. The researchers and Dr. Skolnik had no financial conflicts to disclose. Dr. Skolnik serves on the editorial advisory board of Family Practice News.

In addition, specific measures of cardiometabolic health improved significantly from baseline in the exercise group compared with control children for low-density lipoprotein (change of –7.00 mg/dL), body mass index (–5.9 kg/m2), fat mass index (−0.67), and visceral adipose tissue (31.44 g).
Cardiorespiratory fitness improved by 2.75 laps in the exercise group compared with control children. In addition, significantly more children in the exercise group showed meaningful changes (defined as individual changes of at least 0.2 SDs) compared with control children in measures of fat mass index (37 vs. 17, P < .001) and CRF performance (30 vs. 17, P = .03).
However, no significant effects appeared on mental health outcomes in exercisers, the researchers noted.
The reduction in cardiometabolic score was attributable mainly to improvements in cardiovascular fitness, blood lipid levels, and total and visceral adiposity, the researchers wrote in their discussion. The lack of changes in mental health measures may be a result of the healthy mental state of the children at the study outset, they said. “The null effect on mental health outcomes needs to be further investigated, including, among other things, whether the instruments are sensitive enough to detect changes and whether there is a ceiling effect in young children who might be mentally healthy overall,” they wrote.
The findings were limited by several factors, including the relatively small sample size and lack of blinding for some evaluators. However, the results show the potential of exercise programs to affect meaningful change and improve cardiometabolic health in overweight and obese children, although more research is needed to explore the effects of larger-scale and longer-lasting public health interventions combining exercise and other health behaviors such as diet, the researchers concluded.
Bottom line: Exercise works
The increasing rates of overweight and obesity in children in the United States have “significant downstream consequences that include increased risk of metabolic disease, including diabetes and hypertension, as well as increased rates of anxiety and depression,” Neil Skolnik, MD, professor of family and community medicine at the Sidney Kimmel Medical College of Thomas Jefferson University, Philadelphia, said in an interview.
Therefore, the effect of interventions such as exercise training on outcomes is important, he said.
The current study findings are “what you would hope for and expect – improvement in cardiometabolic parameters and fitness,” said Dr. Skolnik. “It was encouraging to see the effect of this relatively short duration of intervention has a clear positive effect on weight, BMI, and cardiometabolic parameters,” he said. “The real benefit, of course, comes from sustaining these habits over a long period of time.”
The lack of improvement in mental health is not surprising given the small study population “who did not have a high rate of mental health problems to begin with,” Dr. Skolnik added.
Barriers to promoting exercise programs for obese and overweight children in primary care are many, Dr. Skolnik said, including “having the motivation and funding to create programs like this so they are readily available to youth.”
However, the key message from the current study is simple and straightforward, according to Dr. Skolnik. “Exercise works! It works to improve fitness, cardiometabolic parameters, and weight control,” he said.
“There is always room for more research,” Dr. Skolnik added. The questions now are not about whether exercise benefits health; they are about figuring out how to implement the known benefits of exercise into daily living for all children, athletes and nonathletes alike, he said. “We need to find nonjudgmental ways to encourage exercise as a part of routine daily healthy living, up there with brushing teeth every day,” he emphasized.
The study was supported by grants from the Spanish Ministry of Economy and Competitiveness and El Fondo Europeo de Desarrollo Regional (FEDER) and by the MCIN (Ministerio de Ciencia e Innovación) / AEI (Agencia Estatal de Investigación. The researchers and Dr. Skolnik had no financial conflicts to disclose. Dr. Skolnik serves on the editorial advisory board of Family Practice News.

Families with pulmonary fibrosis share trends in disease evolution
Family members with pulmonary fibrosis showed correlations for predicted forced vital capacity trajectories and computed tomography patterns, based on data from 101 individuals in 45 families.
Patients with familial pulmonary fibrosis (FPF), defined as fibrotic interstitial lung disease among two or more first-degree or second-degree relatives, have worse survival than that of patients with sporadic pulmonary fibrosis, wrote Tinne Goos, MD, of KU Leuven, Belgium, and colleagues. Diagnosis of FPF diagnosis is mainly based on family history, and data on intrafamilial correlations are lacking, they said.
In a study published in the journal Chest, the researchers identified FPF patients treated at a single center. The study population included 101 patients from 45 families; most of these (34) were siblings. Overall, 61.4% of the participants were men, 69.3% were ever-smokers, and 84.2% had idiopathic pulmonary fibrosis.
The analysis included data on computed tomography (CT) scanning and predicted forced vital capacity (FVC%), as well as age at diagnosis, treatment type, gender, smoking history, and date of diagnosis.
Overall, FVC%predicted was significantly correlated within families, with a correlation of 0.75. The annual change in FVC was –158.2 mL, and the annual change in FVC%predicted was –6.3%.
Sixty-five patients received antifibrotic treatment, and 18 received immunosuppressive treatment. Immunosuppressive treatment remained significantly correlated among families in a multivariate analysis, with a correlation of 0.77.
“Age at diagnosis correlated within a generation, while patients from a second generation were diagnosed younger,” the researchers noted. The current study findings and results from other studies suggest a genetic basis for FPF age of onset, and determining an age range for screening unaffected relatives based on the age at diagnosis of affected relatives might be useful, they said.
In addition, 42.2% of families showed concordance of CT scan patterns. Typical usual interstitial pneumonia (UIP) appeared in 35 patients, atypical UIP in 36 patients, UIP with emphysema in 9 patients, and findings incompatible with UIP in 21 patients.
The study findings were limited by several factors including the retrospective design and use of data from a single center, as well as by the changes in clinical practice guidelines between 2004 and 2019, with increases in genetic testing, the researchers noted.
However, the current study is the first known to report on FVC evolution within families in FPF, they said. Future studies of both intra- and interfamilial correlation and variability are needed to identify the genetic and environmental factors that may affect disease manifestation and progression, they concluded.
The study was supported by Research Foundation-Flanders. Dr. Goos had no financial conflicts to disclose.

Consistent primary care beforehand may reduce mortality after emergency surgery
Primary care utilization within a year of emergency general surgery was significantly associated with lower mortality up to 180 days later for older adults, based on data from more than 100,000 individuals.
Although previous research has shown the benefits of routine health and preventive care visits for surgery patients, many individuals in the United States live in areas with a shortage of primary care providers, wrote Sanford E. Roberts, MD, of the University of Pennsylvania, Philadelphia, and colleagues. The effect of primary care use on adverse outcomes after emergency general surgery, including mortality, remains unknown, they said.
In a study published in JAMA Surgery the researchers reviewed data from 102,384 Medicare patients aged 66 years and older who underwent emergency general surgery (EGS) between July 1, 2015, and June 30, 2018. Participants were classified into five EGS categories: colorectal, general abdominal, hepatopancreatobiliary, intestinal obstruction, and upper gastrointestinal. The mean age of the participants was 73.8 years; 8.4% were Black, 91.6% were White.
The primary outcome was mortality in hospital and at 30, 60, 90, and 180 days. In the year before hospitalization for EGS, 88,340 patients (86.3%) had visited a primary care physician.
After adjusting for multiple risk factors, the overall risk of in-hospital mortality was 19% lower for patients who had a history of primary care visits than for those without prior-year exposure to primary care (odds ratio, 0.81).
Mortality at 30 days was 27% lower overall in patients with primary care exposure, compared with those without primary care exposure (OR, 0.73). This trend continued at 60 days (OR, 0.75), 90 days (OR, 0.74), and 180 days (OR, 0.75); mortality rates at each time period were similar for Black and White patients with primary care exposure, both groups had reduced mortality, compared with those without primary care exposure.
However, when analyzed by race, in-hospital mortality was not significantly different for Black patients with and without primary care exposure (OR, 1.09), but in-hospital mortality was 21% less in White patients with primary care exposure (OR, 0.79). Interactions between race and primary care exposure related to mortality were not significantly different at any of the follow-up time points of 30, 60, 90, and 180 days.
“These findings suggest that primary care may be exerting a protective effect on postoperative morbidity and mortality,” the researchers wrote in their discussion. “This protective effect could be mediated through several different paths, such as identifying and managing a patient’s comorbidities, medically optimizing patients preoperatively, earlier detection of the primary EGS condition leading to early referral to treatment, and encouraging better lifestyle decisions,” they said.
The findings were limited by several factors including the retrospective design and inability to extract clinical data from a claims database, the researchers noted. Other limitations included potential confounding of unmeasured factors such as the other beneficial health behaviors often associated with seeking primary care.
Patients who avoid primary care may be more likely to delay presentation to the emergency department, which might promote poorer postoperative outcomes, the researchers said. Consequently, surgeons should consider primary care exposure in preoperative assessment, and perform a more comprehensive presurgical assessment as needed, the researchers said.
More studies are needed to examine trends in racial groups, but the results of the current study suggest that primary care provides similar benefits for Black and White individuals, and therefore could help reduce health disparities, they concluded.
Primary care benefits elude many patients
The current study shows a “rather dramatic” association between utilization of primary care within a year before surgery and patient mortality after surgery, wrote Caroline E. Reinke, MD, and David C. Slawson, MD, both of Atrium Health, Charlotte, N.C., in an accompanying editorial. The authors reiterated that possible reasons for the positive effect of primary care on postsurgical mortality included identification and management of comorbidities that could complicate surgery, as well as earlier detection of disease.
However, the editorialists noted that the benefits of primary care exposure depend on patient access to primary care, and on patient adherence to recommendations from their primary care provider. They identified barriers to potential effective interventions with primary care providers including time, money, and transportation.
An unanswered question is “whether the PCP visit itself is the causative factor associated with decreased mortality or if seeing a PCP on an annual basis is a marker of the patient possessing some other ‘magic sauce’ that improves outcomes,” they wrote.
Further, individuals in areas of primary care shortage also are more likely to lack the socioeconomic resources to benefit from primary care, the editorialists said. “Future evaluations of the interaction between PCP visits and social determinants of health may shed light on how to achieve the greatest impact,” they concluded.
Study supports value of consistent primary care
The increasingly aging population across the United States may undergo surgical procedures on an emergent basis and the current study provides data on the benefits of established and effective primary care for these individuals, said Noel Deep, MD, in an interview.
“Having data from this study supports the current position of many physicians and health care organizations and medical professional organizations that older individuals in particular, and adults in general, who have regular routine primary care visits tend to lead healthier lives and have better prognosis and quality of life,” said Dr. Deep, a general internist in private practice in Antigo, Wisc., who was not involved in the study. Dr. Deep also serves as chief medical officer and a staff physician at Aspirus Langlade Hospital in Antigo.
The study findings reinforce what most physicians in primary care, himself included, have been advising adult patients, especially older adults about maintaining regular follow-up visits with their physicians for health screening and management of chronic medical conditions, Dr. Deep said in an interview.
However, barriers to the routine use of primary care to improve postsurgical outcomes include health illiteracy, being overwhelmed by a sudden change in health or emergent surgery, and lack of access to primary care physician, as well as issues such as transportation, financial difficulties, and physical limitations, Dr. Deep added.
“Patients who avoid routine health care visits with primary care may be lacking health insurance or financial resources, have time constraints or family responsibilities, or may be unaware of the benefits of routine health care,” he noted.
As for additional research, “I would like to see studies that can document the impact of having primary care physicians comanage these hospitalized patients in the perioperative period with continued follow-up in the postoperative/convalescent period,” said Dr. Deep.

Verbal working memory deterioration predicts relapse in remitted psychosis
Previous research has suggested that cognitive impairments may predict recurrent psychotic episodes, but data on the association between specific cognitive deficits and relapse of psychosis over time are limited, wrote Tiffany J. Tao, MPhil, a PhD candidate at the University of Hong Kong, and colleagues.
In a naturalistic 1-year follow-up study published in Psychiatry Research , the researchers recruited psychosis patients with full remission for a least 6 months from two outpatient psychiatric clinics. The study population included adults aged 18-55 years, with an average age of 29.2 years; 62% were women. Relapse, defined as a recurrence of psychotic symptoms measured by the Positive and Negative Syndrome Scale (PANSS) and the Clinical Global Impression Scale, was assessed monthly via phone interviews with the use of a smartphone app. Cognitive decline was based on working memory deterioration, assessed monthly via the Visual Patterns Test (VPT) and the Letter-Number Sequencing (LNS) test, respectively, for visual and verbal working memory.
Overall, 18 patients (16%) experienced a relapse at 1 year. One-third of these (six patients) required hospitalization, with a median hospital stay of 23 days.
In a multivariate analysis, independent and significant predictors of relapse were verbal working memory deterioration 2 months prior to relapse (P = .029), worse medication adherence (P = .018), and less resilience (P = .014) with odds ratios of 9.445, 0.051, and 0.769, respectively.
“Specifically, declines in verbal working memory were observed beginning at 2 months prior to the relapse episode in both the univariate and multivariate models after controlling for other significant predictors,” the researchers wrote in their discussion.
The mechanism of action for the association remains unclear, but cognitive impairment might reflect dopamine dysregulation or other processes in the prefrontal cortex that could contribute to psychotic relapse, they said.
Other factors include the associations between cognitive impairment and medication nonadherence, and the impact of cognitive impairment on a patient’s ability to manage the stresses of daily living that could trigger a psychotic relapse, they added.
Notably, the current study identified verbal working memory, but not visual working memory, as a predictor of relapse, which is important given the different neurobiological bases for visual and verbal tasks, the researchers wrote.
The study findings were limited by several factors including the inability to identify weaker predictors of relapse given the low relapse rate, and potential lack of generalizability to other less homogeneous populations, and the exclusion of patients with illicit drug use, the researchers noted.
However, the results were strengthened by the prospective measurements that prevented recall bias, and the inclusion of other objective predictors of relapse. The findings highlight the potential for early intervention to prevent relapse based on cognitive assessment, which can be measured objectively in the clinical setting or remotely from home using digital technology, they concluded.

Previous research has suggested that cognitive impairments may predict recurrent psychotic episodes, but data on the association between specific cognitive deficits and relapse of psychosis over time are limited, wrote Tiffany J. Tao, MPhil, a PhD candidate at the University of Hong Kong, and colleagues.
In a naturalistic 1-year follow-up study published in Psychiatry Research , the researchers recruited psychosis patients with full remission for a least 6 months from two outpatient psychiatric clinics. The study population included adults aged 18-55 years, with an average age of 29.2 years; 62% were women. Relapse, defined as a recurrence of psychotic symptoms measured by the Positive and Negative Syndrome Scale (PANSS) and the Clinical Global Impression Scale, was assessed monthly via phone interviews with the use of a smartphone app. Cognitive decline was based on working memory deterioration, assessed monthly via the Visual Patterns Test (VPT) and the Letter-Number Sequencing (LNS) test, respectively, for visual and verbal working memory.
Overall, 18 patients (16%) experienced a relapse at 1 year. One-third of these (six patients) required hospitalization, with a median hospital stay of 23 days.
In a multivariate analysis, independent and significant predictors of relapse were verbal working memory deterioration 2 months prior to relapse (P = .029), worse medication adherence (P = .018), and less resilience (P = .014) with odds ratios of 9.445, 0.051, and 0.769, respectively.
“Specifically, declines in verbal working memory were observed beginning at 2 months prior to the relapse episode in both the univariate and multivariate models after controlling for other significant predictors,” the researchers wrote in their discussion.
The mechanism of action for the association remains unclear, but cognitive impairment might reflect dopamine dysregulation or other processes in the prefrontal cortex that could contribute to psychotic relapse, they said.
Other factors include the associations between cognitive impairment and medication nonadherence, and the impact of cognitive impairment on a patient’s ability to manage the stresses of daily living that could trigger a psychotic relapse, they added.
Notably, the current study identified verbal working memory, but not visual working memory, as a predictor of relapse, which is important given the different neurobiological bases for visual and verbal tasks, the researchers wrote.

Phenotypes drive antibiotic response in youth with bronchiectasis
Indigenous children or children with new abnormal auscultatory findings were significantly more likely than children in other categories to respond to oral antibiotics for exacerbations related to bronchiectasis, based on data from more than 200 individuals in New Zealand.
Children and adolescents with bronchiectasis are often treated with antibiotics for respiratory exacerbations, but the effects of antibiotics can vary among individuals, and phenotypic features associated with greater symptom resolution have not been identified, wrote Vikas Goyal, PhD, of the Centre for Children’s Health Research, Brisbane, Australia, and colleagues.
Previous studies have suggested that nearly half of exacerbations in children and adolescents resolve spontaneously after 14 days, and more data are needed to identify which patients are mostly likely to benefit from antibiotics, they noted.
In a study published in the journal Chest, the researchers reviewed secondary data from 217 children and adolescents aged 1-18 years with bronchiectasis enrolled in a pair of randomized, controlled trials comparing oral antibiotics with placebo (known as BEST-1 and BEST-2). The median age of the participants was 6.6 years, 52% were boys, and 41% were Indigenous (defined as Australian First Nations, New Zealand Maori, or Pacific Islander). All participants in the analysis received at least 14 days of oral antibiotics for treatment of nonhospitalized respiratory exacerbations.
Overall, 130 children had resolution of symptoms by day 14, and 87 were nonresponders.
In a multivariate analysis, children who were Indigenous or who had new abnormal auscultatory findings were significantly more likely to respond than children in other categories (odds ratios, 3.59 and 3.85, respectively).
Patients with multiple bronchiectatic lobes at the time of diagnosis and those with higher cough scores at the start of treatment were significantly less likely to respond to antibiotics than patients without these features (OR, 0.66 and 0.55, respectively).
The researchers conducted a further analysis to examine the association between Indigenous ethnicity and treatment response. They found no differences in the other response variables of number of affected lobes at diagnosis and cough scores at the start of treatment between Indigenous and non-Indigenous children.
Given the strong response to antibiotics among Indigenous children, the researchers also conducted a mediation analysis. “Respiratory bacterial pathogens were mediated by Indigenous ethnicity and associated with being an antibiotic ‘responder,’ ” they wrote. For new abnormal chest auscultatory findings, both direct and indirect effects on day 14 response to oral antibiotics were mediated by Indigenous ethnicity. However, neither cough scores at the start of treatment nor the number of affected lobes at diagnosis showed a mediation effect from Indigenous ethnicity.
Among the nonresponders, 59 of 87 resolved symptoms with continuing oral antibiotics over the next 2-4 weeks, and 21 improved without antibiotics.
Additionally, the detection of a respiratory virus at the start of an exacerbation was not associated with antibiotic failure at 14 days, the researchers noted.
The findings were limited by several factors including the use of data from randomized trials that were not designed to address the question in the current study, the researchers noted. Other limitations included incomplete clinical data and lack of data on inflammatory indices, potential antibiotic-resistant pathogens in nonresponders, and the follow-up period of only 14 days, they said.
However, the results suggest a role for patient and exacerbation phenotypes in management of bronchiectasis in clinical practice and promoting antimicrobial stewardship, the researchers wrote. “Although there is benefit in treating exacerbations early to avoid treatment failure and subsequent intravenous antibiotics, future research also needs to identify exacerbations that can be managed without antibiotics,” they concluded.
The BEST-1 and BEST-2 studies were supported by the Australian National Health and Medical Research Council and the NHMRC Centre for Research Excellence in Lung Health of Aboriginal and Torres Strait Islander Children. Dr. Goyal had no financial conflicts to disclose.
