Our work aimed to investigate the association between vigorous physical activity and visit-to-visit systolic blood pressure variability (BPV).

We conducted a post hoc analysis of SPRINT (Systolic Blood Pressure Intervention Trial), a well-characterized cohort of participants randomized to intensive (<120 mmHg) or standard (<140 mmHg) SBP targets. We assessed whether patients with hypertension who habitually engage in vigorous physical activity would have lower visit-to-visit systolic BPV compared with those who do not engage in vigorous physical activity. Visit-to-visit systolic BPV was calculated by standard deviation (SD), average real variability (ARV), and standard deviation independent of the mean (SDIM) using measurements taken during the 1-, 2-, 3-, 6-, 9- and 12-month study visits. A medical history questionnaire assessed vigorous physical activity, which was divided into three categories according to the frequency of vigorous physical activity.

A total of 7571 participants were eligible for analysis (34.8% female, mean age 67.9±9.3 years). During a follow-up of 1-year, vigorous physical activity could significantly reduce SD, ARV, and SDIM across increasing frequency of vigorous physical activity.

Long-term engagement in vigorous physical activity was associated with lower visit-to-visit systolic BPV.

Mitochondria are hubs for metabolite and energy generation. Mitochondria are also highly dynamic in their function modulating their composition, size, density, and the network-like architecture in relation to the metabolic demands of the cell. Here, we review the recent research on the post-transcriptional regulation of mitochondrial composition focusing on mRNA localization, mRNA translation, protein import, and the role that dynamic mitochondrial structure may have on these gene expression processes. As mitochondrial structure and function has been shown to be very important for age-related processes, including cancer, metabolic disorders, and neurodegeneration, understanding how mitochondrial composition can be affected in fluctuating conditions can lead to new therapeutic directions to pursue.Hypertension is both a cause and a consequence of central artery stiffening, which in turn is an initiator and indicator of myriad disease conditions and thus all-cause mortality. Such stiffening results from a remodeling of the arterial wall that is driven by mechanical stimuli and mediated by inflammatory signals, which together lead to differential gene expression and concomitant changes in extracellular matrix composition and organization. This review focuses on biomechanical mechanisms by which central arteries remodel in hypertension within the context of homeostasis - what promotes it, what prevents it. It is suggested that the vasoactive capacity of the wall and inflammatory burden strongly influence the ability of homeostatic mechanisms to adapt the arterial wall to high blood pressure or not. Maladaptation, often reflected by inflammation-driven adventitial fibrosis, not just excessive intimal-medial thickening, significantly diminishes central artery function and disturbs hemodynamics, ultimately compromising end organ perfusion and thus driving the associated morbidity and mortality. It is thus suggested that there is a need for increased attention to controlling both smooth muscle phenotype and inflammation in hypertensive remodeling of central arteries, with future studies of the often adaptive response of medium-sized muscular arteries promising to provide additional guidance.
Due to the advent and success of antiretroviral therapy (ART), the number of people living and aging with HIV has grown substantially. Although PLHIV are experiencing longer life expectancies, this achievement may be undermined by increasing and disproportionate chronic disease burden among PLHIV.

This study is a retrospective analysis of adult (≥18 years) inpatient hospital discharges from a large hospital system in the New York City, New York metropolitan area, between January 1st, 2006 and December 31st, 2016. We aimed to investigate 1) changes in the prevalence of Charlson-defined comorbidities among PLHIV hospitalized between 2006 and 2016, and 2) changes in the unadjusted prevalence ratio (PR) of comorbidities in HIV-positive versus HIV-negative admissions over time.

Of 898,139 hospital admissions from 2006-2016, 19,039 (2.1%) were HIV-positive. Across all admissions during the study period, the greatest comorbidity disparities between HIV-positive and HIV-negative admissions were mild liver disease (PR=4.9, 95% CI [4.8,5.1]), moderate or severe liver disease (PR=2.2 [2.0,2.4]), and chronic pulmonary disease (PR=1.8 [1.8,1.8]).

The prevalence and relative burden of comorbidities among hospitalized PLHIV is changing over time. Careful monitoring and intensive discharge planning may be effective strategies for addressing the evolving health needs of PLHIV.

The majority of the human genome has the capacity to be transcribed and the majority of the non-protein-coding transcripts made by RNA Polymerase II are enriched in the nucleus. Many chromatin regulators can bind to these ncRNAs in the nucleus; in some cases, there are clear examples of direct RNA-mediated chromatin regulation mechanisms stemming from these interactions, while others have yet to be determined. Recent studies have highlighted examples of chromatin regulation via RNA matchmaking, a term we use broadly here to describe intermolecular base-pairing interactions between one RNA molecule and an RNA or DNA match. This review provides examples of RNA matchmaking that regulates chromatin processes and summarizes the technical approaches used to capture these events.
