Dietary Inflammatory Score and Incident Heart Failure in the Reasons for Geographic and Racial Differences in Stroke (REGARDS) Study.

Background: Inflammation plays a key role in the development of heart failure (HF), and diet is a known modifiable factor that modulates systemic inflammation. The dietary inflammatory score (DIS) is a tool to quantify the inflammatory components of diet. We sought to determine whether the DIS is associated with incident HF events.

Examining Healthy Lifestyles as a Mediator of the Association Between Socially Determined Vulnerabilities and Incident Heart Failure.

Background: Increased burden of socially determined vulnerabilities (SDV), which include nonmedical conditions that contribute to patient health, is associated with incident heart failure (HF). Mediators of this association have not been examined. We aimed to determine if a healthy lifestyle mediates the association between SDV and HF.

The Cumulative Burden of Social Risk Factors and 10-Year Change in Quality of Life.

Background: Social risk factors are linked to adverse health outcomes, but their total impact on long-term quality of life is obscure. We hypothesized that a higher burden of social risk factors is associated with greater decline in quality of life over 10 years.

Methods: We examined associations between social risk factors count and decline >5 points in (i) physical component summary, and (ii) mental component summary scores from the Short Form-12 among Black and White participants in the Reasons for Geographic and Racial Differences in Stroke study (n = 14 401).

Changes in Medication Complexity and Post-Hospitalization Outcomes in Older Adults Hospitalized for Heart Failure.

Introduction: Medication regimen complexity may be an important risk factor for adverse outcomes in older adults with heart failure. However, increasing complexity is often necessary when prescribing guideline-directed medical therapy at the time of a heart failure hospitalization. We sought to determine whether increased medication regimen complexity following a heart failure hospitalization was associated with worse post-hospitalization outcomes.

2024 Update of the RECOVER-Adult Long COVID Research Index.

Importance: Classification of persons with long COVID (LC) or post-COVID-19 condition must encompass the complexity and heterogeneity of the condition. Iterative refinement of the classification index for research is needed to incorporate newly available data as the field rapidly evolves.

Objective: To update the 2023 research index for adults with LC using additional participant data from the Researching COVID to Enhance Recovery (RECOVER-Adult) study and an expanded symptom list based on input from patient communities.

Plasma Biomarkers of Kidney Health and Mortality in Diabetes and Chronic Kidney Disease in the REGARDS Study.

Key Points: In diabetes and CKD, creatinine- and cystatin C–based eGFR has a strong inverse correlation with plasma TNF receptor 1, TNF receptor 2, and soluble urokinase-type plasminogen activator receptor. Higher plasma soluble TNF receptors 1 and 2 and soluble urokinase-type plasminogen activator receptor were each individually associated with mortality, independent of baseline kidney measures.

Background: Several plasma biomarkers of kidney health have been associated with CKD progression in persons with diabetes, but their associations with mortality risk have been largely unexplored.

Association of Integrase Strand Transfer Inhibitor-Based Antiretroviral Therapy With Blood Pressure and Sustained Hypertension in People With Human Immunodeficiency Virus.

Background: Integrase strand transfer inhibitors (INSTIs) are a commonly used antiretroviral therapy (ART) class in people with human immunodeficiency virus (HIV) and associated with weight gain. We studied the association of INSTI-based ART with systolic and diastolic blood pressure (SBP and DBP).

Methods: We recruited 50 people taking INSTI-based ART and 40 people taking non-INSTI-based ART with HIV and hypertension from the University of Alabama at Birmingham HIV clinic.

Cardiometabolic Disease Staging and Major Adverse Cardiovascular Event Prediction in 2 Prospective Cohorts.

Background: Cardiometabolic risk prediction models that incorporate metabolic syndrome traits to predict cardiovascular outcomes may help identify high-risk populations early in the progression of cardiometabolic disease.

Objectives: The purpose of this study was to examine whether a modified cardiometabolic disease staging (CMDS) system, a validated diabetes prediction model, predicts major adverse cardiovascular events (MACE).

Methods: We developed a predictive model using data accessible in clinical practice [fasting glucose, blood pressure, body mass index, cholesterol, triglycerides, smoking status, diabetes status, hypertension medication use] from the REGARDS (REasons for Geographic And Racial Differences in Stroke) study to predict MACE [cardiovascular death, nonfatal myocardial infarction, and/or nonfatal stroke].

Regional and rural-urban patterns in the prevalence of diagnosed hypertension among older U.S. adults with diabetes, 2005-2017.

Background: Hypertension prevalence among the overall US adult population has been relatively stable during the last two decades. However, whether this stabilization has occurred across rural-urban communities and across different geographic regions is unknown, particularly among older adults with diabetes who are likely to have concomitant cardiovascular risk factors.

Methods: This serial cross-sectional analysis used the 5% national sample of Medicare administrative claims data (n = 3,516,541) to examine temporal trends (2005-2017) in diagnosed hypertension among older adults with diabetes, across urban-rural communities and US census regions (Northeast, Midwest, South, and West).

Why location matters: associations between county-level characteristics and availability of National Cancer Oncology Research Program and National Cancer Institute sites.

Background: The majority of patients with cancer seek care at community oncology sites; however, most clinical trials are available at National Cancer Institute (NCI)-designated sites. Although the NCI National Cancer Oncology Research Program (NCORP) was designed to address this problem, little is known about the county-level characteristics of NCORP site locations.

Methods: This cross-sectional analysis determined the association between availability of NCORP or NCI sites and county-level characteristic theme percentile scores from the Center for Disease Control and Prevention's Social Vulnerability Index themes.

Characteristics and determinants of pulmonary long COVID.

BACKGROUNDPersistent cough and dyspnea are prominent features of postacute sequelae of SARS-CoV-2 (also termed "long COVID"); however, physiologic measures and clinical features associated with these pulmonary symptoms remain poorly defined. Using longitudinal pulmonary function testing (PFT) and CT imaging, this study aimed to identify the characteristics and determinants of pulmonary long COVID.METHODSThis single-center retrospective study included 1,097 patients with clinically defined long COVID characterized by persistent pulmonary symptoms (dyspnea, cough, and chest discomfort) lasting for 1 or more months after resolution of primary COVID infection.

Population-average mediation analysis for zero-inflated count outcomes.

Mediation analysis is an increasingly popular statistical method for explaining causal pathways to inform intervention. While methods have increased, there is still a dearth of robust mediation methods for count outcomes with excess zeroes. Current mediation methods addressing this issue are computationally intensive, biased, or challenging to interpret.

Imaging Neuropeptide Release from Clock and Motor Neurons.

Electrophysiological studies of synaptic function do not robustly report release of neuropeptides and neurotrophins. These limitations have been overcome with the presynaptic expression of optical release reporters based on green fluorescent protein and fluorogen-activating protein. Here we describe how to image neuropeptide release in at the neuromuscular junction and in the adult brain.
