Importance: Despite aging-related comorbidities representing a growing threat to quality-of-life and mortality among persons with HIV (PWH), clinical guidance for comorbidity screening and prevention is lacking. Understanding comorbidity distribution and severity by sex and gender is essential to informing guidelines for promoting healthy aging in adults with HIV.

Objective: To assess the association of human immunodeficiency virus on the burden of aging-related comorbidities among US adults in the modern treatment era.

Objective: The optimal time to start biologics in polyarticular juvenile idiopathic arthritis (JIA) remains uncertain. The Childhood Arthritis and Rheumatology Research Alliance (CARRA) developed 3 consensus treatment plans (CTPs) for untreated polyarticular JIA to compare strategies for starting biologics.

Methods: Start Time Optimization of Biologics in Polyarticular JIA (STOP-JIA) was a prospective, observational, CARRA Registry study comparing the effectiveness of 3 CTPs: 1) the step-up plan (initial nonbiologic disease-modifying antirheumatic drug [DMARD] monotherapy, adding a biologic if needed, 2) the early combination plan (DMARD and biologic started together), and 3) the biologic first plan (biologic monotherapy).

Mechanisms and Models in Heart Failure: A Translational Approach.

Circ Res

May 2021

Duke Clinical Research Institute and Duke University School of Medicine, Durham, Duke University, NC (G.M.F.).

Despite multiple attempts to develop a unifying hypothesis that explains the pathophysiology of heart failure with a reduced ejection fraction (HFrEF), no single conceptual model has withstood the test of time. In the present review, we discuss how the results of recent successful phase III clinical development programs in HFrEF are built upon existing conceptual models for drug development. We will also discuss where recent successes in clinical trials do not fit existing models to identify areas where further refinement of current paradigms may be needed.

Background: Chronic heart failure with reduced ejection fraction impairs health-related quality of life (HRQL). Omecamtiv mecarbil (OM)-a novel activator of cardiac myosin-improves left ventricular systolic function and remodeling and reduces natriuretic peptides. We sought to evaluate the effect of OM on symptoms and HRQL in patients with chronic heart failure with reduced ejection fraction and elevated natriuretic peptides enrolled in the COSMIC-HF trial (Chronic Oral Study of Myosin Activation to Increase Contractility in Heart Failure).

Background: The prevalence and burden of age-related non-AIDS comorbidities (NACMs) are poorly characterized among women living with HIV (WLWH).

Methods: Virologically suppressed WLWH and HIV-seronegative participants followed in the Women's Interagency HIV Study (WIHS) through at least 2009 (when >80% of WLWH used antiretroviral therapy) were included, with outcomes measured through 31 March 2018. Covariates, NACM number, and prevalence were summarized at most recent WIHS visit.

Article Synopsis
  • * The analysis included 22 studies involving nearly 2,000 HFpEF patients, revealing significantly lower LA reservoir, conduit, and pump emptying fractions in these patients compared to healthy individuals.
  • * Findings suggest that impaired LA function could be a useful diagnostic and prognostic marker for HFpEF, but more extensive research is necessary to confirm its effectiveness in clinical settings and explore potential new treatment options.

Article Synopsis
  • - The study aimed to evaluate the safety and tolerability of sustained caloric restriction (CR) over two years in healthy, non-obese adults, as this had not been examined before.
  • - Participants were divided into two groups: one group followed a CR diet with a 25% calorie reduction, while the other group consumed an unrestricted diet. Some adverse events were monitored, with a few participants experiencing safety concerns.
  • - Overall, the CR was found to be safe and well tolerated, but it was noted that participants on CR had lower bone mineral density and certain health issues compared to those with unrestricted intake, highlighting the need for careful monitoring for bone loss and anemia.

Article Synopsis
  • Caloric restriction (CR) appears to increase lifespan in various species, and it has been studied in a 2-year trial involving 218 nonobese humans aged 21-51 to assess its feasibility, safety, and impact on health metrics.
  • Participants were divided into a CR group aiming for 25% energy intake reduction and an ad libitum (AL) group, with results showing significant changes in resting metabolic rates, thyroid hormone levels, and other health indicators favoring the CR group.
  • The study concluded that sustained CR is achievable in nonobese individuals without negatively affecting quality of life and may have beneficial implications for aging and disease risk, warranting further research.

Background: The Multicenter Unsustained Tachycardia Trial (MUSTT) was designed to evaluate an antiarrhythmic treatment strategy, including drugs and implantable defibrillators (ICDs), guided by electrophysiological (EP) testing. We performed several statistical analyses to assess the contribution of defibrillators to the observed treatment benefit.

Methods And Results: First, the effects of defibrillators were indirectly examined by comparing the randomized treatment arms (EP-guided therapy versus no antiarrhythmic therapy) within subgroups that varied according to ICD usage.
