Among adults with psoriatic arthritis (PsA), 11.8% required at least one musculoskeletal surgery related to their disease, based on data from more than 1,500 individuals at the University of Toronto’s Psoriatic Arthritis Clinic.

“Despite optimal medical therapy to control systemic inflammation and preserve joint function, a subset of patients with PsA still require musculoskeletal (MSK) surgery for disease-related morbidity,” but data on the prevalence of MSK surgeries and the associated risk factors are lacking, wrote Timothy S.H. Kwok, MD, of the University of Toronto, and colleagues.

In a study published in The Journal of Rheumatology, the researchers reviewed data from a longitudinal cohort of 1,574 adults aged 18 years and older with PsA established at the Toronto clinic during 1978-2019.

Overall, 185 patients had 379 MSK surgeries related to PsA during the study period for a prevalence of 11.8%.

The most common procedures were arthrodesis and arthroplasty (27% for both). More than half (59%) of the surgeries were joint sacrificing, and 41% were joint retaining, and 57 procedures were revisions related to the primary surgery.

Among 1,018 patients with data complete enough for a multivariate analysis, including 71 PsA surgeries, factors significantly associated with an increased risk for surgery were a higher number of damaged joints (hazard ratio [HR], 1.03; P < .001), tender or swollen joints (HR, 1.04; P = .01), and the presence of nail lesions (HR, 2.08; P < .01). Other predictors of surgery were higher scores on the Health Assessment Questionnaire (HR, 2.01; P < .001), elevated erythrocyte sedimentation rate (HR, 2.37; P = .02), and HLA-B27 positivity (HR, 2.22; P = .048).

However, a higher score on the Psoriasis Area Severity Index was significantly associated with lower risk of surgery (HR, 0.88; P < .002) The use of biologics had no significant impact on MSK surgery, the researchers noted.

The high percentage of joint sacrificing surgeries suggests a high burden of MSK surgery in patients with PsA, the researchers wrote in their discussion. The current study supports findings from previous studies and highlights the potential limitations and need for improvement in the current medical treatment paradigm for PsA, they said.

The findings were limited by several factors, including the potential for referral bias of complex cases to the center, which might have caused overestimation of the number of surgeries. The similarity in surgeries specifically related to PsA and degenerative arthritis also makes overestimation of surgeries possible, the researchers noted.

However, the study is one of the largest known to evaluate the prevalence of risk factors for MSK surgery in PsA patients over a long period of time, and identified surgeries directly attributable to PsA, they said. The study ended prior to the onset of the COVID-19 pandemic, which increased the external validity of the findings, they added.

The study was supported by the Krembil Foundation. The researchers had no financial conflicts to disclose.

Two-thirds of children who underwent genetic testing in the pediatric intensive care unit showed a genetic variant, and a third of these children received changes in care as a result, according to a new study presented at the Society of Critical Care Medicine’s 2023 Critical Care Congress.

“We have had a lot of success using genome sequencing to help not only with diagnosis, but also changes in management,” lead author Katherine Rodriguez, MD, a pediatric critical care fellow physician at Rady Children’s Hospital, San Diego, told this news organization.

However, data on the use of rapid whole genome sequencing (rWGS) in the pediatric intensive care unit (PICU) are limited, and data from multiple institutions are lacking, Dr. Rodriguez said. In the current study, data from multiple hospitals allowed the researchers to examine differences in management across institutions, she said.

Dr. Rodriguez, with principal investigator Nicole Coufal, MD, also of Rady Children’s, and colleagues conducted the study at three children’s hospitals from March 2019 to July 2022. The study population included 80 children whose origin of illness was uncertain. The patients underwent rWGS testing in the PICU or cardiac ICU setting. The patients ranged in age from 0 to 17 years; 64% were younger than 1 year, (mean age, 2.8 years); 56% were male, and 59% were White.  

After rWGS testing, 65% of the children were positive for a genetic variant. The data prompted changes to care for 42% of these patients; 38% of the changes occurred during the patient’s PICU stay, including medication changes and procedures that were either avoided or completed.

The remaining 62% of the changes were subacute and affected management for the remainder of the child’s hospitalization and after discharge, Dr. Rodriguez explained in her presentation.

The average turnaround time for the testing was 10 days, which is important to an intensivist, who may have been hesitant to order tests because of the time involved, Dr. Rodriguez said. The current study shows that “we can get test results in a reasonable time to make meaningful changes in care,” she told this news organization.

Choosing which patients to test can be a challenge for clinicians, Dr. Rodriguez acknowledged. “We have gotten a sense of which patients are likely to have diagnostic or not diagnostic genomes, but it is also a gut feeling,” she said.

“If this child is your patient and you are concerned, if they seem sicker than expected, or have a concerning family history, then send the test,” she said. “It is becoming more affordable, and can come back quickly enough to guide treatment while the patient is still in the ICU.”

In the current study, the greatest diagnostic utility appeared in patients with cardiac symptoms, such as congenital heart disease, sudden cardiac arrest, or suspected channelopathy, Dr. Rodriguez said in her presentation.

Patients with suspected neurological disease had a 50% rate of molecular diagnosis. “Interestingly, 74% of patients with respiratory disease where an underlying genetic etiology was suspected received a molecular diagnosis,” although rWGS was not applied to general populations with RSV or other respiratory illnesses, she said.

In her presentation, Dr. Rodriguez shared examples of how genetic testing had a dramatic impact on patient survival. In one case, a 14-year-old girl presented in cardiac arrest and was found to have new-onset dilated cardiomyopathy. Whether the etiology was acquired or infectious and possibly reversible or genetic was unclear, she said.

“A diagnostic genome result within 48 hours indicated a genetic etiology,” she said. The patient was listed for heart transplant despite the incomplete infectious workup, and received a successful heart transplant 1 week after admission, Dr. Rodriguez said.

Guidelines for which PICU patients should undergo genetic testing do not yet exist, Dr. Rodriguez told this news organization. “We are trying to find some more meaningful parameters where we can say that a patient has a high pretest possibility of a genetic condition,” she said.

“Increasing availability of rWGS can significantly impact patient care and assist families in making difficult decisions during times of critical illness,” she said.

Insurance coverage and testing access are improving, said Dr. Rodriguez. Medicaid policies exist for neonates/infants in the ICU in several states, including Oregon, California, Michigan, Maryland, and Louisiana, she said. In some areas, hospitals may pay for testing for these children if insurance will not, she added.

Dr. Rodriguez and colleagues are continuing to enroll patients in a prospective study of the impact of rWGS, with the addition of a fourth study site and inclusion of family surveys. “We also will be looking at a secondary analysis of cost savings and benefits,” she said.

Ultimately, the current study should be empowering to physicians, “especially if they don’t have good access to geneticists,” Dr. Rodriguez said in an interview.

The study received no outside funding. Dr. Rodriguez reports no relevant financial relationships.

Elevated depressive symptoms were associated with an additional brain age of nearly 3 years, based on data from more than 600 individuals.

Previous research suggests a possible link between depression and increased risk of dementia in older adults, but the association between depression and brain health in early adulthood and midlife has not been well studied, wrote Christina S. Dintica, PhD, of the University of California, San Francisco, and colleagues.

In a study published in the Journal of Affective Disorders, the researchers identified 649 individuals aged 23-36 at baseline who were part of the Coronary Artery Risk Development in Young Adults (CARDIA) study. All participants underwent brain MRI and cognitive testing. Depressive symptoms were assessed six times over a 25-year period using the Center for Epidemiological Studies Depression scale (CES–D), and the scores were analyzed as time-weighted averages (TWA). Elevated depressive symptoms were defined as CES-D scores of 16 or higher. Brain age was assessed via high-dimensional neuroimaging. Approximately half of the participants were female, and half were Black.

Overall, each 5-point increment in TWA depression symptoms over 25 years was associated with a 1-year increase in brain age, and individuals with elevated TWA depression averaged a 3-year increase in brain age compared with those with lower levels of depression after controlling for factors including chronological age, sex, education, race, MRI scanning site, and intracranial volume, they said. The association was attenuated in a model controlling for antidepressant use, and further attenuated after adjusting for smoking, alcohol consumption, income, body mass index, diabetes, and physical exercise.

The researchers also investigated the impact of the age period of elevated depressive symptoms on brain age. Compared with low depressive symptoms, elevated TWA CES-D at ages 30-39 years, 40-49 years, and 50-59 years was associated with increased brain ages of 2.43, 3.19, and 1.82.

In addition, elevated depressive symptoms were associated with a threefold increase in the odds of poor cognitive function at midlife (odds ratio, 3.30), although these odds were reduced after adjusting for use of antidepressants (OR, 1.47).

The mechanisms of action for the link between depression and accelerated brain aging remains uncertain, the researchers wrote in their discussion. “Studies over the last 20 years have demonstrated that increased inflammation and hyperactivity of the hypothalamic-pituitary-adrenal (HPA) axis are two of the most consistent biological findings in major depression, which have been linked to premature aging,” they noted. “Alternative explanations for the link between depression and adverse brain health could be underlying factors that explain both outcomes rather independently, such as low socioeconomic status, childhood maltreatment, or shared genetic effects,” they added.

Adjustment for antidepressant use had little effect overall on the association between depressive symptom severity and brain age, they said.

The current study findings were limited by the single assessment of brain age, which prevented evaluation of the temporality of the association between brain aging and depression, the researchers noted.

However, the results were strengthened by the large and diverse cohort, long-term follow-up, and use of high-dimensional neuroimaging, they said. Longitudinal studies are needed to explore mechanisms of action and the potential benefits of antidepressants, they added.

In the meantime, monitoring and treating depressive symptoms in young adults may help promote brain health in midlife and older age, they concluded.

The CARDIA study was supported by the National Heart, Lung, and Blood Institute, the National Institute on Aging, and the Alzheimer’s Association. The researchers had no financial conflicts to disclose.

A restrictive fluid strategy had no significant impact on mortality in patients with sepsis-induced hypotension compared to the typical liberal fluid strategy, based on data from 1,563 individuals.

Intravenous fluids are standard in the early resuscitation of sepsis patients, as are vasopressor agents, but data comparing restrictive or liberal use in these patients are limited, wrote Nathan I. Shapiro, MD, of Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, and colleagues.

In a study published in the New England Journal of Medicine the researchers randomized 782 patients to the restrictive fluid group and 781 to the liberal fluid group. Patients aged 18 years and older were enrolled between March 7, 2018, and Jan. 31, 2022, at 60 centers in the United States. Participants were randomized within 4 hours of meeting the criteria for sepsis-induced hypotension that was refractory to initial treatment with 1-3 L of intravenous fluid. Baseline characteristics were similar between the groups. At randomization, 21% of patients in the restrictive fluid group and 18% in the liberal fluid group received vasopressors.

The primary outcome was 90-day all-cause mortality, which occurred in 109 and 116 patients in the liberal and restricted groups, respectively (approximately 14% of each group). No significant differences were noted among subgroups based on factors including systolic blood pressure and the use of vasopressors at randomization, chronic heart failure, end-stage renal disease, and pneumonia.

The restrictive fluid protocol called for vasopressors as the primary treatment for sepsis-induced hypotension, with “rescue fluids” to be used for prespecified situations of severe intravascular volume depletion. The liberal fluid protocol was a recommended initial intravenous infusion of 2,000 mL of isotonic crystalloid, followed by fluid boluses given based on clinical triggers such as tachycardia, along with “rescue vasopressors,” the researchers wrote.

The median volume of fluid administered in the first 24-hour period after randomization was 1,267 mL in the restrictive group and 3,400 mL in the liberal group. Adherence to the treatment protocols was greater than 90% for both groups.

The current study is distinct in its enrollment of patients with primary presentations of sepsis to a hospital emergency department, the researchers wrote in their discussion. “The patients who were enrolled in this trial were representative of the types of patients who present to the hospital with sepsis-induced hypotension; we expect our findings to be generalizable to these types of patients,” they said.

Reported serious adverse events were similar between the groups, though fewer episodes of fluid overload and pulmonary edema occurred in the restricted group.

The findings were limited by several factors including some cases in which patients in the restrictive group received more fluid than called for by the protocol, the researchers noted. Other limitations included the lack of subgroups with different coexisting conditions, the lack of blinding, and the lack of a control with no instructions for treatment protocol, they said. However, the results suggest that a restrictive fluid strategy had no significant advantage over a liberal strategy in terms of mortality for patients with sepsis-induced hypotension, they concluded.

The study was supported by the National Heart, Lung, and Blood Institute. Dr. Shapiro disclosed serving as a consultant for and having stock options in Diagnostic Robotics, as well as grant support from Inflammatrix and Rapid Pathogen Screening, and serving as a consultant for Prenosis.

A restrictive fluid strategy had no significant impact on mortality in patients with sepsis-induced hypotension compared to the typical liberal fluid strategy, based on data from 1,563 individuals.

Intravenous fluids are standard in the early resuscitation of sepsis patients, as are vasopressor agents, but data comparing restrictive or liberal use in these patients are limited, wrote Nathan I. Shapiro, MD, of Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, and colleagues.

In a study published in the New England Journal of Medicine the researchers randomized 782 patients to the restrictive fluid group and 781 to the liberal fluid group. Patients aged 18 years and older were enrolled between March 7, 2018, and Jan. 31, 2022, at 60 centers in the United States.

A 12-month program of moderate to vigorous exercise reduced the risk of type 2 diabetes by approximately 50% in adults with obesity over 10 years, according to a new analysis of a study.

“Physical exercise combined with diet restriction has been proven to be effective in prevention of diabetes. However, the long-term effect of exercise on prevention of diabetes, and the difference of exercise intensity in prevention of diabetes have not been well studied,” said corresponding author Xiaoying Li, MD, of Zhongshan Hospital, Fudan University, Shanghai, in an interview.

In the research letter published in JAMA Internal Medicine, Dr. Li and colleagues analyzed the results of a study of 220 adults with central obesity and nonalcoholic fatty liver disease, but no incident diabetes, randomized to a 12-month program of vigorous exercise (73 patients), moderate aerobic exercise (73 patients) or no exercise (74 patients).

A total of 208 participants completed the 1-year intervention; of these, 195 and 178 remained to provide data at 2 years and 10 years, respectively. The mean age of the participants was 53.9 years, 32.3% were male, and the mean waist circumference was 96.1 cm at baseline.

The cumulative incidence of type 2 diabetes in the vigorous exercise, moderate exercise, and nonexercise groups was 2.1 per 100 person-years 1.9 per 100 person-years, and 4.1 per 100 person-years, respectively, over the 10-year follow-up period. This translated to a reduction in type 2 diabetes risk of 49% in the vigorous exercise group and 53% in the moderate exercise group compared with the nonexercise group.

In addition, individuals in the vigorous and moderate exercise groups significantly reduced their HbA1c and waist circumference compared with the nonexercisers. Levels of plasma fasting glucose and weight regain were lower in both exercise groups compared with nonexercisers, but these differences were not significant.

The exercise intervention was described in a 2016 study, which was also published in JAMA Internal Medicine. That study’s purpose was to compare the effects of exercise on patients with nonalcoholic fatty liver disease. Participants were coached and supervised for their exercise programs. The program for the vigorous group involved jogging for 150 minutes per week at 65%-80% of maximum heart rate for 6 months and brisk walking 150 minutes per week at 45%-55% of maximum heart rate for another 6 months. The program for the moderate exercise group involved brisk walking 150 minutes per week for 12 months.

Both exercise groups showed a trend towards higher levels of leisure time physical activity after 10 years compared with the nonexercise groups, although the difference was not significant.

The main limitation of the study was that incident prediabetes was not prespecified, which may have led to some confounding, the researchers noted. In addition, the participants were highly supervised for a 12-month program only. However, the results support the long-term value of physical exercise as a method of obesity management and to delay progression to type 2 diabetes in obese individuals, they said. Vigorous and moderate aerobic exercise programs could be implemented for this patient population, they concluded.

“Surprisingly, our findings demonstrated that a 12-month vigorous aerobic exercise or moderate aerobic exercise could significantly reduce the risk of incident diabetes by 50% over the 10-year follow-up,” Dr. Li said in an interview. The results suggest that physical exercise for some period of time can produce a long-term beneficial effect in prevention of type 2 diabetes, he said.

Potential barriers to the routine use of an exercise intervention in patients with obesity include the unwillingness of this population to engage in vigorous exercise, and the potential for musculoskeletal injury, said Dr. Li. In these cases, obese patients should be encouraged to pursue moderate exercise, Dr. Li said.

Looking ahead, more research is needed to examine the potential mechanism behind the effect of exercise on diabetes prevention, said Dr. Li.

Findings fill gap in long-term outcome data

The current study is important because of the long-term follow-up data, said Jill Kanaley, PhD, professor and interim chair of nutrition and exercise physiology at the University of Missouri, in an interview. “We seldom follow up on our training studies, thus it is important to see if there is any long-term impact of these interventions,” she said.

Dr. Kanaley said she was surprised to see the residual benefits of the exercise intervention 10 years later.

“We often wonder how long the impact of the exercise training will stay with someone so that they continue to exercise and watch their weight; this study seems to indicate that there is an educational component that stays with them,” she said.

The main clinical takeaway from the current study was the minimal weight gain over time, Dr. Kanaley said.

Although time may be a barrier to the routine use of an exercise intervention, patients have to realize that they can usually find the time, especially given the multiple benefits, said Dr. Kanaley. “The exercise interventions provide more benefits than just weight control and glucose levels,” she said.

“The 30-60 minutes of exercise does not have to come all at the same time,” Dr. Kanaley noted. “It could be three 15-minute bouts of exercise/physical activity to get their 45 minutes in,” she noted. Exercise does not have to be heavy vigorous exercise, even walking is beneficial, she said. For people who complain of boredom with an exercise routine, Dr. Kanaley encourages mixing it up, with activities such as different exercise classes, running, or walking on a different day of any given week.

Although the current study was conducted in China, the findings may translate to a U.S. population, Dr. Kanaley said in an interview. However, “frequently our Western diet is less healthy than the traditional Chinese diet. This may have provided an immeasurable benefit to these subjects,” although study participants did not make specific adjustments to their diets, she said.  

Additional research is needed to confirm the findings, said Dr. Kanaley. “Ideally, the study should be repeated in a population with a Western diet,” she noted.

Next steps for research include maintenance of activity

Evidence on the long-term benefits of exercise programs is limited, said Amanda Paluch, PhD, a physical activity epidemiologist at the University of Massachusetts, Amherst, in an interview.

“Chronic diseases such as diabetes can take years to develop, so understanding these important health outcomes requires years of follow-up. This study followed their study participants for 10 years, which gives us a nice glimpse of the long-term benefits of exercise training on diabetes prevention,” she said.

Data from previous observational studies of individuals’ current activity levels (without an intervention) suggest that adults who are more physically active have a lower risk of diabetes over time, said Dr. Paluch. However, the current study is one of the few with rigorous exercise interventions with extensive follow-up on diabetes risk, and it provides important evidence that a 12-month structured exercise program in inactive adults with obesity can result in meaningful long-term health benefits by lowering the risk of diabetes, she said.

“The individuals in the current study participated in a structured exercise program where their exercise sessions were supervised and coached,” Dr. Paluch noted. “Having a personalized coach may not be within the budget or time constraints for many people,” she said. Her message to clinicians for their patients: “When looking to start an exercise routine, identify an activity you enjoy and find feasible to fit into your existing life and schedule,” she said.

“Although this study was conducted in China, the results are meaningful for the U.S. population, as we would expect the physiological benefit of exercise to be consistent across various populations,” Dr. Paluch said. “However, there are certainly differences across countries at the individual level to the larger community-wide level that may influence a person’s ability to maintain physical activity and prevent diabetes, so replicating similar studies in other countries, including the U.S., would be of value.” 

“Additionally, we need more research on how to encourage maintenance of physical activity in the long-term, after the initial exercise program is over,” she said.

“From this current study, we cannot tease out whether diabetes risk is reduced because of the 12-month exercise intervention or the benefit is from maintaining physical activity regularly over the 10 years of follow-up, or a combination of the two,” said Dr. Paluch. Future studies should consider teasing out participants who were only active during the exercise intervention, then ceased being active vs. participants who continued with vigorous activity long-term, she said.

The study was supported by the National Nature Science Foundation, the National Key Research and Development Program of China, and the Shanghai Municipal Science and Technology Major Project. The researchers, Dr. Kanaley, and Dr. Paluch had no financial conflicts to disclose.

Previous studies have shown reduced muscle mass in asthma patients, but the impact on clinical and functional outcomes has not been well studied, wrote Edith Visser, MSc, of Medical Centre Leeuwarden (the Netherlands) and colleagues.

“Many asthma patients, especially those with severe disease, report exercise intolerance and limitations in daily activities, severely affecting their quality of life,” they said. Research into the clinical consequences of low muscle mass and low muscle strength for patients with asthma and the role of inflammation could make muscle function a potential treatment target for those with asthma, they said.

In a study published in the Journal of Allergy and Clinical Immunology: In Practice, the researchers recruited 114 consecutive adults aged 18 years and older with a diagnosis of moderate to severe asthma who were seen at a single center between Jun. 2019 and Oct. 2022. The mean age of the patients was 51.9 years, 36% were men, 70% were overweight or obese, and 34 were diagnosed with severe asthma.

Participants underwent clinical, functional, and laboratory assessments at one or two visits within a 2-week period. Assessment tools included the Asthma Quality of Life Questionnaire (AQLQ), the Asthma Control Questionnaire (ACQ-6), a questionnaire on health care use (HCU), and the ‘short questionnaire to assess health-enhancing physical activity’ (SQUASH).

Functional activity was based on the 6-minute walking distance (6MWD), and lung function tests included spirometry and fractional inhaled nitric oxide (FeNO). Muscle mass was based on fat-free mass index (FFMI) and urinary creatinine excretion rate (CER). Muscle strength was measured using hand-grip strength (HGS).

The researchers examined levels of muscle mass and strength and their relation to functional and clinical outcomes.

Overall, the mean measures of muscle mass and strength were higher in males, who had average FFMI, CER, and HGS measures of 20.1 kg/m², 15.3 mmol/day, and 48.8 kg, respectively. These measures in women were 17.3 kg/m², 10.8 mmol/day, and 29.3 kg, respectively.

After adjusting for confounding factors, patients in the lowest tertile for muscle mass based on FFMI had significantly more severe asthma based on postbronchodilator forced expiratory volume in 1 second and FEV₁/forced vital capacity, as well as lower functional exercise capacity based on the 6MWD compared to those in the highest tertile. A similar association appeared between CER and FEV₁, but not FEV₁/FVC.

However, no significant associations appeared between the muscle mass measures of FFMI or CER and scores on the ACQ, AQLQ, emergency department visits, or asthma exacerbations, the researchers noted.

No relationship appeared between muscle strength and functional outcomes. However, patients in the lowest tertile of HGS had worse asthma control, worse quality of life, and a higher probability of at least one visit to the emergency department compared to patients in the highest HGS tertile.

Higher leukocyte levels were significantly associated with lower muscle mass after adjusting for age, sex, weight, and physical activity, but no other inflammatory markers were significantly associated with FFMI.

The association between lower muscle strength and poorer asthma control, lower quality of life, and greater odds of emergency department visits reflect findings from previous studies, the researchers said. The mechanisms behind the loss of muscle strength in asthma remain unclear, but physical inactivity and daily oral corticosteroid use may play a role, they added.

The study findings were limited by the cross-sectional design and the possibility that muscle weakness may instead stem from reduced physical activity associated with poor lung function and asthma control, the researchers noted. Other limitations included the potential overestimation of FFMI and the lack of statistical power to show a relationship between FFMI and emergency department visits and asthma exacerbations, they said.

However, the current study is the first known to explore the relationship between lower muscle mass and strength and a range of both functional and clinical outcomes in patients with moderate to severe asthma, they said.

“Our findings encourage longitudinal studies into muscle function as a potential target for treatment to improve asthma outcomes,” they concluded.

A model incorporating factors such as lymphocytes and lung lesions differentiated adenovirus pneumonias from Chlamydia psittaci (CPP) in a multicenter study of nearly 200 individuals.

Symptoms of pneumonia caused by CPP are often confused with other respiratory infections, particularly adenovirus pneumonia (AVP), which can delay correct diagnosis and impact treatment, Yi Li, MD, of Xiangya Hospital, Central South University, Changsha, China, and colleagues wrote. Detailed comparisons of the two conditions are lacking.

In a retrospective study published in the International Journal of Infectious Diseases, the researchers examined laboratory, clinical, and radiological differences and created a nomogram to distinguish CPP from AVP. The study population included 78 adults with CPP and 102 with AVP who were seen at a single center in China. The mean ages of the CPP and AVP patients were 61.0 years and 38.5 years, and 57.7% men and 91.2% men, respectively. Patients with CPP were significantly more likely to have hypertension and diabetes at baseline, compared with the AVP group.

The primary outcome was 30-day mortality after hospital admission, which was 10.3% and 14.7% for the CPP and AVP patients, respectively (P = 0.376). However, the incidence of cardiac injury was significantly higher in AVP patients versus those with CPP (48.0% vs. 11.5%; P < 0.001).

In a multivariate analysis, age, sex, nervous system symptoms, lymphocyte count, C-reactive protein level (CRP), and bilateral lung lesions were risk factors for CPP. The researchers combined these factors into a nomogram that showed a concordance value of 0.949 for differentiating between the CPP and AVP groups.

Overall, CPP patients were older, had more nervous system symptoms, and had higher CRP levels, compared with patients with AVP, who were more likely to be men and to have higher lymphocyte percentages and more bilateral lung lesions on chest imaging.

The current study is the first known to provide a way to distinguish CPP and AVP, the researchers wrote. “The antibiotic treatments, prognoses, and life support measures of CPP and AVP are considerably different. Therefore, differentiating the two diseases through early identification of specific clinical characteristics is vital.”

The findings were limited by several factors including the small sample size, retrospective design, and the use of mNGS to diagnose CPP in the absence of standard clinical diagnostic kits, which may have resulted in underestimated CPP incidence, the researchers noted.

However, “the nomogram we established combines patient data on age, sex, and readily available laboratory results to reasonably predict CPP, thus making rapid and direct diagnosis possible,” they said.

Fluorescence-optical imaging (FOI) identified early signs of psoriatic arthritis, based on data from 2 years of follow-up of a cohort of 389 adults at 14 rheumatology centers.

Approximately 25% of individuals with psoriasis go on to develop psoriatic arthritis (PsA), but there are no validated biomarkers to identify patients at risk for progression to PsA, Michaela Koehm, MD, of Goethe University, Frankfurt am Main, Germany, and colleagues wrote in RMD Open.

FOI is a technique that allows assessment of changes in microvascularization and subdermal skin inflammation, and because individuals with psoriasis who develop PsA have shown changes in blood vessel formation in the early stages of disease, the researchers sought to determine if FOI could be used to predict early PsA.

The researchers conducted a multicenter, two-part observational cohort study. The two parts, known as XCITING and XTEND, included 389 adults aged 18-75 years with plaque psoriasis deemed at increased risk for PsA. The patients were seen at rheumatology sites in Germany between Jan. 28, 2014, and March 16, 2017. The XTEND study included clinic visits 18-24 months after the XCITING study.

Participants underwent a complete clinical examination, with musculoskeletal ultrasound (MSUS) and FOI on both hands at a single visit. Those with positive FOI findings not seen with clinical exam or MSUS underwent MRI within 7 days. Patients with positive FOI but negative findings on clinical exam, MSUS, and MRI were followed for 2 years in the XTEND study.

The primary outcome was the ability of FOI to detect musculoskeletal inflammation, compared with clinical examination and MSUS.

Overall, 50% of the patients were diagnosed with PsA. A total of 116 (30%) had positive FOI findings; complete MRI data were available for 108 of these patients, including 68 negative MRIs and 40 positive MRIs.

In the XTEND study, another 12% of patients who were positive on FOI but not on MRI also developed PsA by the end of the 2-year follow-up. In comparison, the researchers noted that “literature data on yearly incidence rates [of PsA] in different national cohorts indicate an incidence rate of approximately 4.3% per year.”

A total of 149 of the 196 patients with PsA confirmed by either clinical exam or MSUS were also positive on FOI, yielding a sensitivity of 76.0%. The specificity of FOI was 39.5%.

The sensitive visualization of musculoskeletal inflammation possible with FOI “may exceed its ability to detect clinically manifest PsA at high sensitivity or specificity, but early visualization is arguably of greater value as other imaging methods are currently available for detection of later stages of PsA,” the researchers wrote in their discussion. “A technique allowing early identification of PsA may be especially valuable for nonrheumatologists, including dermatologists and general practitioners, and help expedite more efficient referral to specialists.”

The findings were limited by several factors, including the nonrandomized design and small subgroup numbers, the researchers noted. Other limitations include the presence of alternative conditions such as osteoarthritis that might have complicated the imaging; the focus only on the hands; and potential variation in FOI assessment related to technical standards such as temperature and positioning.

However, the results support FOI as a safe and effective method of detecting early signs of joint inflammation that could predict increased risk for PsA in psoriasis patients, the researchers said.

The researchers added that more work is needed to evaluate FOI in clinical practice, but FOI has the potential to identify vascularization changes earlier than other imaging modalities and in advance of clinical symptoms.

“Accordingly, FOI may have the potential to improve patient outcomes in PsA by reducing the time to initiation of early treatment,” they concluded.

The study was supported by Fraunhofer ITMP, a nonprofit organization, and a research grant from Pfizer Germany. Some of the researchers disclosed financial relationships with many pharmaceutical companies, including Pfizer.

A diabetes screening program built into an electronic medical records system identified diabetes or prediabetes in 52% of individuals flagged for abnormal hemoglobin A1c, based on data from more than 2,000 adults.

“Despite the best efforts of clinicians, researchers, and educators, the number of patients living with undiagnosed diabetes is still rising and is currently at approximately 8.5 million, and the number of people unaware of their prediabetes is approximately 77 million,” lead investigator Kristie K. Danielson, PhD, said in an interview. Screening for diabetes is critical to start treatment early, to potentially reverse prediabetes, and to prevent the long-term complications of diabetes and reduced life expectancy.

In a pilot study published in JAMA Network Open, Dr. Danielson and colleagues reviewed data from 8,441 adults who visited a single emergency department in Chicago during February–April 2021.

The EMR at the hospital contained a built-in best practice alert (BPA) that flagged patients as being at risk for type 2 diabetes based the American Diabetes Association recommendations; the identification algorithm included age 45 years and older, or those aged 18-44 years with a body mass index of 25 kg/m² or higher, no previous history of diabetes, and no A1c measure in the last 3 years, according to the EMR.

A total of 8,441 adult patients visited the ED during the study period; 2,576 triggered BPA tests, and 2,074 had A1c results for review. Among the patients with A1c results, 52% had elevated values of 5.7% or higher. Of these, a total of 758 individuals were identified with prediabetes (A1c, 5.7%-6.4%), 265 with diabetes (A1c, 6.5%-9.9%), and 62 with severe diabetes (A1c, 10% or higher).

After testing, 352 patients with elevated A1c were contacted by the researchers. The mean age of this group was 52.2 years, 54.5% were women, and nearly two-thirds (64.8%) were non-Hispanic Black. The median income of those contacted was in the 44th percentile, and 50% had public insurance.

Most of those contacted (264 patients) were not aware of a previous diagnosis of prediabetes or diabetes; the remaining 88 had a previous diagnosis, but only 51 self-reported receiving treatment, the researchers noted.

Although the screening program successfully identified a significant number of previously undiagnosed individuals with diabetes, prediabetes, or poorly controlled diabetes, its feasibility in routine practice requires further study, the researchers wrote.

The findings were limited by several factors including the identification of patients previously diagnosed with diabetes but who were not being treated, and the potential bias toward individuals of higher socioeconomic status, the researchers noted. However, the results support further exploration of the program as a way to identify undiagnosed diabetes, especially in underserved populations.
 

Diabetes in underserved groups goes undetected

“We were surprised by the sheer number of people newly diagnosed with diabetes or prediabetes,” which was far greater than expected, commented Dr. Danielson of the University of Illinois at Chicago. “Clearly, we tapped into a new population that has not often been seen by primary care providers or endocrinologists, as is often the case for underserved and vulnerable individuals who visit the emergency department as a first line for health care.”

The screening alert system is straightforward to build into an existing EMR, with technical support, Dr. Danielson said. “In theory, it should be able to be incorporated into other clinical centers and emergency departments. One of the current limitations that we are seeing is that the EMR is still flagging some people already diagnosed with diabetes to be screened for diabetes.” However, “because of this, we also see this as an opportunity to identify and reach out to those with diabetes who are still underserved and not receiving the appropriate diabetes care they need.”

The study results have broader public health implications, Dr. Danielson added. “We have identified a new, large population of people with diabetes who need medical care and diabetes education. This will further add to the burden of health care and costs, and it raises the ethical question of screening and not having full resources readily available to help.

“In my opinion, the study sheds light on a significant issue that will hopefully help drive change at both a health systems and public health level locally and nationally,” she added.

“One of the significant research gaps that has emerged now is how to link these new patients to health care and diabetes education at our institution after they leave the emergency department,” said Dr. Danielson. Diabetes screening in the ED setting is “a very novel area for health system scientists, social workers, and others to now come to the table and collaborate on next steps to help our patients.”

The study was initiated by the investigators, but was supported by a grant from Novo Nordisk to two coauthors. Dr. Danielson also disclosed grant funding from Novo Nordisk during the conduct of the study.

A diabetes screening program built into an electronic medical records system identified diabetes or prediabetes in 52% of individuals flagged for abnormal hemoglobin A1c, based on data from more than 2,000 adults.

“Despite the best efforts of clinicians, researchers, and educators, the number of patients living with undiagnosed diabetes is still rising and is currently at approximately 8.5 million, and the number of people unaware of their prediabetes is approximately 77 million,” lead investigator Kristie K. Danielson, PhD, said in an interview. Screening for diabetes is critical to start treatment early, to potentially reverse prediabetes, and to prevent the long-term complications of diabetes and reduced life expectancy.

In a pilot study published in JAMA Network Open, Dr. Danielson and colleagues reviewed data from 8,441 adults who visited a single emergency department in Chicago during February–April 2021.

The EMR at the hospital contained a built-in best practice alert (BPA) that flagged patients as being at risk for type 2 diabetes based the American Diabetes Association recommendations; the identification algorithm included age 45 years and older, or those aged 18-44 years with a body mass index of 25 kg/m² or higher, no previous history of diabetes, and no A1c measure in the last 3 years, according to the EMR.

A total of 8,441 adult patients visited the ED during the study period; 2,576 triggered BPA tests, and 2,074 had A1c results for review. Among the patients with A1c results, 52% had elevated values of 5.7% or higher. Of these, a total of 758 individuals were identified with prediabetes (A1c, 5.7%-6.4%), 265 with diabetes (A1c, 6.5%-9.9%), and 62 with severe diabetes (A1c, 10% or higher).

Individuals diagnosed with a severe physical health condition were significantly more likely to commit suicide at 6 months and at 1 year later, based on data from more than 47 million individuals in a national database.

Previous smaller studies have shown a link between increased risk for suicide and a range of health conditions including cancer, coronary heart disease, neurologic conditions, diabetes, and osteoporosis, Vahé Nafilyan, PhD, of the Office for National Statistics, Newport, England, and colleagues wrote.

However, large-scale population-level studies of the association between specific diagnoses and suicide are lacking, they said.

In a study published in The Lancet Regional Health–Europe, the researchers reviewed a dataset that combined the 2011 Census, death registration records, and the Hospital Episode Statistics. The study population included 47,354,696 individuals aged 6 years and older living in England in 2017. The mean age of the study population was 39.6 years, and 52% were female. The researchers examined deaths that occurred between Jan. 1, 2017, and Dec. 31, 2021.

The primary outcome was the time from the date of a diagnosis or first treatment of a severe physical health condition to a death by suicide. The health conditions included in the analysis were low-survival cancers, chronic ischemic heart disease, chronic obstructive pulmonary disease, and degenerative neurological disease.

The diagnosis of any of these conditions significantly increased the risk for suicide compared with controls. The highest risk appeared within 6 months of a diagnosis or first treatment, but the increased risk persisted at 1 year.

The suicide rate among low-survival cancer patients was 16.6 per 100,000 patients, compared with 5.7 per 100,000 controls; at 1 year, these rates were 21.6 and 9.5 per 100,000 patients and controls, respectively.

For COPD patients, the suicide rate at 6 months after diagnosis was 13.7 per 100,000 patients versus 5.6 per 100,000 matched controls; the suicide rates at 1 year were 22.4 per 100,000 patients and 10.6 per 100,000 matched controls.

The suicide rate at 6 months for individuals diagnosed with chronic ischemic heart disease was 11.0 per 100,000 patients and 4.2 per 100,000 matched controls; at 1 year, the suicide rates were 16.1 per 100,000 patients and 8.8 per 100,000 matched controls.

The 1-year suicide rate was especially high among patients with degenerative neurological conditions (114.5 per 100,000 patients); however, the estimate was considered imprecise because of the rarity of these diseases and subsequent low number of suicides, the researchers noted.

The results support data from previous studies showing links between increased risk of suicide and severe physical conditions, the researchers wrote. Patterns of suicide were similar between men and women and after adjusting for sociodemographic factors.

The findings were limited by the inability to fully control for a history of depression or self-harm, and by the imprecise estimates given the rare occurrence of suicide overall, the researchers noted. Other limitations included the late registration of deaths from external causes and the focus only on suicides that occurred in England and Wales, meaning that individuals who traveled abroad for assisted suicide were not captured in the dataset.

“Further research is needed to understand the mechanisms driving the elevated risk of suicide and help provide the best support to these patients,” the researchers concluded.

However, the current results enhance the literature with a large, population-based review of the elevated suicide risk among individuals newly diagnosed with severe health conditions, and reflect the need for better support for these patients to help with coping, they said.

The study was funded by the Office for National Statistics. The researchers reported no relevant financial relationships.
