Filter by:With the opening up of the two-child policy , the composition of pregnant women in China has changed significantly . The proportion of high-risk pregnant women in the elderly has increased significantly , and the risk of adverse pregnancy outcomes has also increased . Among them , gestational diabetes mellitus ( GDM ) is the most common complication during pregnancy . The incidence of GDM in China is as high as 18 % due to the economic growth , lifestyle changes and dietary habits . GDM not only threatens perinatal maternal and child health , but also increases the risk of offspring insulin resistance , obesity and metabolic diseases in adulthood . But it is still lack of experience on intervening and managing them effectively. Therefore , on the basis of previous studies , this study intends to explore the effects of intensive diet and exercise intervention by obstetricians and nutritionists on pregnancy weight gain , pregnancy outcome , glucose and lipid metabolism and postpartum weight retention under the mobile medical platform through a large sample cluster intervention test in the real world. In order to supervise and improve the compliance of the intervention subjects and realize the ultimate change of their behaviors, this study intends to use the APP software, the mobile medical technology, to monitor and evaluate diet , exercise and weight. Through the above research , it aims to improve the current management schemes of diet and weight during pregnancy , not only helps to optimize and improve the quality of perinatal health care , but also prevents the adult chronic diseases from the fetal period. This research has important theoretical and practical value .
An Investigator initiated trial (IIT) using a prospective, randomized, double-blind, parallel group, placebo-controlled, clinical study design.
Obese individuals have a higher prevalence of nocturnal hypertension and non-dipping blood pressure (BP). These conditions are associated with an increased risk of cardiovascular (CV) events and death. Natriuretic Peptides (NPs) are hormones produced by the heart which directly regulate BP by causing dilation of blood vessels and by removing sodium and water from the body. NPs have a 24-hour day-night rhythm and this controls the day-night rhythm of BP as well. The NP-BP rhythm relationship is broken down in obese individuals. Obese individuals also have lower circulating NP levels. Lower circulating levels of NPs and elevated renin hormone (a part of the Renin-Angiotensin-Aldosterone System [RAAS]) at nighttime may contribute to the high nocturnal blood pressure in obese individuals which puts them at a higher risk of developing CV events. This current study seeks to determine the biological implications of chronopharmacology for synchronizing NP-RAAS-based blood pressure therapy with the physiological diurnal rhythms to restore the normal diurnal rhythm of blood pressure in obese individuals.
Pulmonary arterial hypertension (PAH) is a progressive disease in which clinically relevant symptoms present a few years after the onset in rise of pulmonary arterial pressure. Increased PA pressure presents an overload on the right ventricle (RV), with RV failure being a common cause of mortality in PAH. Current therapeutic targets help reduce vascular resistance and RV afterload, however, RV dysfunction may continue to progress. Therefore, the reason for RV failure in PAH cannot be contributed to altered vascular hemodynamics alone but may be related to metabolic alterations and failure of adaptive mechanisms in the RV. Providing a better understanding of metabolic remodeling in RV failure may permit the development of RV-targeted pharmacological agents to maintain RV function despite increased pulmonary vascular pressures. This study will evaluate how cardiac metabolism changes in response to pulmonary vasodilator therapy in patients with pulmonary arterial hypertension.
High sodium intake is a significant risk factor for hypertension. Recently, animal studies connect high sodium intake to the gut-immune axis and highlight the gut microbiome as a potential therapeutic target to counteract salt-sensitive conditions and hypertension. The objective of this project is to determine the effects of high salt intake on gut microbiota composition and gut intestine barrier integrity, leading to increased BP in humans. The investigators also hypothesize that high salt intake affects the gut microbiome in a sex-specific manner. In this pilot study, The investigators also test whether telehealth or in-person nutritional coaching help to decrease dietary sodium intake and improve diet quality
This is an open-label, single-armed, prospective single-centre clinical study to evaluate the effect of riociguat on right heart size and function in patients with manifest PAH and CTEPH.
This is a Phase 2, double-blind, randomized, placebo-controlled study to evaluate the efficacy and safety of sotatercept versus placebo in adults with Cpc-PH due to HFpEF. The objective of this study is to evaluate the efficacy, safety and tolerability of sotatercept versus placebo in adults with Cpc-PH due to HFpEF. Efficacy is measured by change from baseline in pulmonary vascular resistance (PVR, primary endpoint) and 6-minute walk distance (6MWD, key secondary endpoint).
In this project, the investigators will perform a multicenter randomised controlled trial to determine whether advice to consume a moderate, whole food-based low-carbohydrate high-fat (LCHF) ad libitum diet (CarbCount program) can produce and maintain equal remission rates of type 2 diabetes (T2D) as a nutritionally complete very-low-calorie formula diet followed by a energy-restrictive (i.e., calorie counting) diet (DiRECT principles). Within the principles of each approach, the dietary goals and change will be adjusted according to individual needs/capabilities conducive to long-term adherence. Furthermore, the investigators aim to determine whether the rate of diet-induced remission is reflected in/can be predicted by baseline or diet-induced changes in glucose variability (e.g., time-in-range measured by continuous glucose monitoring) and other factors such as anthropometric changes and genetic susceptibility. Each center will also conduct locally-lead standalone mechanistic research, including analyses of intra-abdominal/hepatic fat accumulation, adipose tissue biopsies and/or measurements of energy metabolism. Additionally, changes in medication use, nutritional status, cardiovascular disease risk, as well as adverse events, will be monitored.
This clinical research study will investigate the effects of respiratory strength training on blood pressure and cardiovascular health in adults who are 50 years of age and older and have been diagnosed with moderate or severe obstructive sleep apnea.
This is a retrospective case series study that included patients who performed deep anterior lamellar keratoplasty and presented with elevated intraocular pressure during follow up.
