Effects of vitamin D supplementation on cardiac biomarkers: Results from the STURDY trial.

Objectives: In observational studies, older adults with low serum vitamin D levels are at higher risk of cardiovascular disease (CVD), but randomized trials have failed to demonstrate reduction in CVD risk from vitamin D supplementation, possibly because the doses of vitamin D supplements tested were too low. Our objective was to determine if higher doses of vitamin D supplementation reduce high-sensitivity cardiac troponin (hs-cTnI) and N-terminal pro-b-type natriuretic peptide (NT-proBNP), markers of subclinical CVD.

Methods: The Study to Understand Fall Reduction and Vitamin D in You (STURDY) was a double-blind, randomized, response-adaptive trial that tested the effects of 4 doses of vitamin D3 supplementation (200, 1000, 2000, 4000 IU/day) on fall risk among older adults with low serum 25-hydroxyvitamin D concentrations (10-29 ng/mL).

Neighborhood Socioeconomic Status and Cardiovascular Events in Adults With CKD: The CRIC Study.

Rationale & Objective: In the general population, neighborhood socioeconomic status (SES) has been found to be associated with cardiovascular risk, but this relationship has not been well studied among patients with chronic kidney disease (CKD). This study seeked to evaluate the association between neighborhood SES and cardiovascular outcomes in a CKD cohort.

Study Design: Multicenter prospective cohort.

Cigar, Pipe, and Smokeless Tobacco Use and Cardiovascular Outcomes From Cross Cohort Collaboration.

Importance: Cardiovascular health outcomes associated with noncigarette tobacco products (cigar, pipe, and smokeless tobacco) remain unclear, yet such data are required for evidence-based regulation.

Objective: To investigate the association of noncigarette tobacco products with cardiovascular health outcomes.

Design, Setting, And Participants: This cohort study was conducted within the Cross Cohort Collaboration Tobacco Working Group by harmonizing tobacco-related data and conducting a pooled analysis from 15 US-based prospective cohorts with data on the use of at least 1 noncigarette tobacco product ranging between 1948 and 2015.

Surrogate End Points in Apolipoprotein L1 - Associated Kidney Disease : Evaluation in Three Cohorts.

Key Points: Apolipoprotein L1 (APOL1) high-risk genotype had higher risk of 3-year GFR-related surrogate end points and long-term kidney failure than those with the low-risk genotype. No consistent difference in surrogate–clinical outcome associations by APOL1 genotype, supporting the use of surrogates in APOL1 kidney disease.

Background: Surrogate end points for the clinical outcome of kidney failure have been accepted by the US Food and Drug Administration.

Task-sharing with community health workers to treat hypertension: a scoping review.

Many studies have implemented and evaluated task-sharing interventions with community health workers (CHWs) to manage hypertension. To identify gaps in research, we conducted a scoping review. We searched original articles published in PubMed and EMBASE between 2010 and 2022 and found 122 articles meeting our inclusion criteria.

Arm Position and Blood Pressure Readings: The ARMS Crossover Randomized Clinical Trial.

Importance: Guidelines for blood pressure (BP) measurement recommend arm support on a desk with the midcuff positioned at heart level. Still, nonstandard positions are used in clinical practice (eg, with arm resting on the lap or unsupported on the side).

Objective: To determine the effect of different arm positions on BP readings.

Protein Biomarkers of Ultra-Processed Food Consumption and Risk of Coronary Heart Disease, Chronic Kidney Disease, and All-Cause Mortality.

Background: There is a need to understand the underlying biological mechanisms through which ultra-processed foods negatively affect health. Proteomics offers a valuable tool with which to examine different aspects of ultra-processed foods and their impact on health.

Objectives: The aim of this study was to identify protein biomarkers of usual ultra-processed food consumption and assess their relation to the incidence of coronary heart disease (CHD), chronic kidney disease (CKD), and all-cause mortality risk.

Associations of Hypertension and Orthostatic Hypotension With Subclinical Cardiovascular Disease.

Background: Orthostatic hypotension is associated with cardiovascular disease. It remains unclear if low standing blood pressure or high seated blood pressure is responsible for this association. We compared associations of orthostatic hypotension and hypertension with high-sensitivity cardiac troponin I and N-terminal pro-B-type natriuretic peptide.

Serum protein responses to Dietary Approaches to Stop Hypertension (DASH) and DASH-Sodium trials and associations with blood pressure changes.

Objectives: The Dietary Approaches to Stop Hypertension (DASH) diet reduces blood pressure, but the mechanisms underlying DASH diet-blood pressure relations are not well understood. Proteomic measures may provide insights into the pathophysiological mechanisms through which the DASH diet reduces blood pressure.

Methods: The DASH (1994-1996) and DASH-Sodium (1997-1999) trials were multicenter, randomized-controlled feeding trials.

Evaluation of the World Health Organization-HEARTS hypertension control package in Bangladesh: a quasi-experimental trial.

Background: The World Health Organization (WHO) promotes the HEARTS technical package for improving hypertension control worldwide, but its effectiveness has not been rigorously evaluated.

Objective: To compare hypertension outcomes in clinics implementing HEARTS versus clinics continuing usual hypertension care in rural Bangladesh.

Methods: A matched-pair cluster quasi-experimental trial in Upazila Health Complexes (UHCs; primary healthcare facilities) was conducted in rural Bangladesh.

Ultra-processed food consumption and risk of diabetes: results from a population-based prospective cohort.

Aims/hypothesis: Understanding the impact of the overall construct of ultra-processed foods on diabetes risk can inform dietary approaches to diabetes prevention. In this study, we aimed to evaluate the association between ultra-processed food consumption and risk of diabetes in a community-based cohort of middle-aged adults in the USA. We hypothesised that a higher intake of ultra-processed foods is associated with a higher risk of incident diabetes.

Behavioral Weight Loss Programs for Cancer Survivors Throughout Maryland: Protocol for a Pragmatic Trial and Participant Characteristics.

Background: Clinical trials examining lifestyle interventions for weight loss in cancer survivors have been demonstrated to be safe, feasible, and effective. However, scalable weight loss programs are needed to support their widespread implementation. The ASPIRE trial was designed to evaluate real-world, lifestyle-based, weight loss programs for cancer survivors throughout Maryland.

Differences in weight-loss outcomes among race-gender subgroups by behavioural intervention delivery mode: An analysis of the POWER trial.

Prior in-person behavioural intervention studies have documented differential weight loss between men and women and by race, with Black women receiving the least benefit. Remotely delivered interventions are now commonplace, but few studies have compared outcomes by race-gender groups and delivery modality. We conducted a secondary analysis of POWER, a randomized trial (NCT00783315) designed to determine the effectiveness of 2 active, lifestyle-based, weight loss interventions (remote vs.

Dihydropyridine Calcium Channel Blockers and Kidney Outcomes.

Background: Early trials of dihydropyridine calcium channel blockers (DCCBs) suggest a detrimental effect on intraglomerular pressure and an association with albuminuria.

Objective: We sought to evaluate the associations of DCCB initiation with albuminuria and kidney failure with replacement therapy (KFRT) and to determine whether renin-angiotensin system (RAS) blockade modified these associations.

Design: We conducted a target trial emulation study using a new user, active comparator design and electronic health record data from Geisinger Health.

Effect of Isocaloric, Time-Restricted Eating on Body Weight in Adults With Obesity : A Randomized Controlled Trial.

Background: Time-restricted eating (TRE) lowers body weight in many studies. Whether TRE induces weight loss independent of reductions in calorie intake, as seen in rodent studies, is unknown.

Objective: To determine the effect of TRE versus a usual eating pattern (UEP) on body weight in the setting of stable caloric intake.

On-demand mobile hypertension training for primary health care workers in Nigeria: a pilot study.

Background: Only one out of every ten Nigerian adults with hypertension has their blood pressure controlled. Health worker training is essential to improve hypertension diagnosis and treatment. In-person training has limitations that mobile, on-demand training might address.

Outpatient COVID-19 convalescent plasma recipient antibody thresholds correlated to reduced hospitalizations within a randomized trial.

BACKGROUNDCOVID-19 convalescent plasma (CCP) virus-specific antibody levels that translate into recipient posttransfusion antibody levels sufficient to prevent disease progression are not defined.METHODSThis secondary analysis correlated donor and recipient antibody levels to hospitalization risk among unvaccinated, seronegative CCP recipients within the outpatient, double-blind, randomized clinical trial that compared CCP to control plasma. The majority of COVID-19 CCP arm hospitalizations (15/17, 88%) occurred in this unvaccinated, seronegative subgroup.

Effects of Reduced Dietary Sodium and the DASH Diet on GFR: The DASH-Sodium Trial.

Key Points: Sodium reduction over a 4-week period decreased eGFR. Combining sodium reduction with the Dietary Approaches to Stop Hypertension diet resulted in larger reductions in eGFR. Changes in diastolic BP seem partially responsible for the observed dietary effects.

Potassium-Enriched Salt Substitutes: A Review of Recommendations in Clinical Management Guidelines.

Excess dietary sodium intake and insufficient dietary potassium intake are both well-established risk factors for hypertension. Despite some successful initiatives, efforts to control hypertension by improving dietary intake have largely failed because the changes required are mostly too hard to implement. Consistent recent data from randomized controlled trials show that potassium-enriched, sodium-reduced salt substitutes are an effective option for improving consumption levels and reducing blood pressure and the rates of cardiovascular events and deaths.
