Filter by:This study will examine markers of vascular endothelial function (vascular health) and metabolic profiles in older versus younger transgender men (people who were assigned female at birth but whose gender identity is male). Data will also be compared to those from age group-matched transgender women and cisgender women and men.
Flavonoids are polyphenolic compound mainly found in fruits and vegetables with numerous beneficial health effects as protection against cardiovascular diseases by an antihypertensive effect. The intestinal microbiota plays a key role in the metabolization of these compounds, so that differences in the composition and activity of the microbiota between individuals can generate different metabotypes. Flavonoids are found mainly in their conjugated form linked to the monosaccharide rhamnose and need to be metabolized by the intestinal bacteria, releasing the rhamnose, to be absorbed and, thus, bioactive. The bacterial enzyme responsible of rhamnose hydrolysis is α-L-rhamnosidase, whose activity can vary considerably depending on the composition of the microbiota. In fact, a great interindividual variability has been observed in the ability to absorb flavonoids, which allows to classify individuals according to the corresponding metabotype. In a previous project, the investigators confirmed the interindividual differences in the bioavailability of hesperidin and narirutin, two flavonoids naturally present in orange juice. However, the role of the intestinal microbiota in the metabolism of hesperidin and narirutin needs to be elucidated. On this basis, the following hypothesis is presented: individuals with arterial hypertension can be classified into 3 different metabotypes that are the result of the ability to absorb hesperidin and narirutin, determined by the urinary excretion of their respective metabolites, and these metabotypes are associated with different microbiota enterotypes and with different fecal α-L-rhamnosidase activity.
Fluid therapy guided by stroke volume response to repeated fluid challenges is used for hemodynamic optimization during general anesthesia. Two types of devices that measure stroke volume non-invasively are primarily available for intermediate-risk surgery under general anesthesia. They are based on two different techniques, (1) pulse contour analysis, and (2) transthoracic bioimpedance. They have never been compared with each other. Therefore, it is not known (1) whether they are interchangeable for the measurement of stroke volume changes (usually assessed as the "concordance" of two techniques), and (2) whether one is better than the other. The aim is to study the concordance of these two non-invasive hemodynamic devices. it will use both of them in patients undergoing intermediate risk surgery. They will be tested during modifications of cardiac preload induced by Trendelenburg and anti-Trendelenburg positioning, as well as during intraoperative fluid challenges, vasopressor boluses and alveolar recruitment maneuvers.
The purpose of the study is to investigate the association between inpatient blood pressure levels and in-hosopital adverse outcomes.
An open label, prospective, single center, pilot trial to assess feasibility and tolerability of short term blood pressure augmentation to minimize infarct progression in acute LVO stroke patients undergoing endovascular therapy.
The goal of this study is to develop and validate a new non-invasive medical instrumentation technology for blood pressure measurement.
The primary objective of this research is to collect data to develop an algorithm for continuous, non-inflating measurement of absolute, long-term Blood Pressure using the CS6BP device and to evaluate the safety of the CS6BP.
China is entering an aging society. As the number of elderly population continues to increase, the elderly are facing many social problems that deserve the attention of all sectors of society. Hypertension is one of the common diseases in the elderly population. Hypertension is the most common chronic diseases and a most important risk factor for cardiovascular and cerebrovascular diseases, and also a substantial public health problem. Home blood pressure monitoring is simple, not only can find hypertension, but also can guide the treatment of patients with hypertension. The purpose of the study is to investigate the association between home blood pressure and adverse outcomes in community elderly population.
This study will incorporate critical cross viscero-visceral intersystem interactions to 1) investigate in a controlled laboratory setting and then with mobile at-home monitoring the extent, severity, and frequency of occurrence of autonomic dysreflexia with respect to daily bladder and bowel function, in conjunction with identifying potential underlying mechanisms by examining urinary biomarkers for several specific vasoactive hormones, and 2) to regulate cardiovascular function therapeutically as part of bladder and bowel management using spinal cord epidural stimulation.
The current study examined the influence of an acute weight stigma exposure on cardiovascular reactivity among women with obesity and high blood pressure and women with obesity and normal blood pressure.
