Frailty has been proposed as a measure of biological (as opposed to chronological) aging. In this study the investigators plan to: (1) measure frailty in a cohort of older HIV-infected individuals in Hong Kong, and its association with mortality and quality of life; (2) identify risk factors predictive of development of frailty in HIV-infected individuals in Hong Kong; and (3) determine the outcomes of HIV-infected individuals in Hong Kong with and without frailty. The following assessment will be done: 1. Physical examination including measuring height, weight, hip and waist circumference. 2. Grip strength, chair stand test, gait speed test, balance tests, and neurocognitive tests 3. Geriatric syndromes, screening for depression, disability and quality of life. 4. Blood tests during fasting state to measure metabolic parameters. This is a prospective longitudinal observational study that lasts for 10 years.
Assessment of Change in AtheROSclerotic Plaque by Serial CCTA (ACROSS) is designed as a prospective observational study which aim is to demonstrate the effect of statins on coronary atherosclerosis, assessed by quantitative analysis of CCTA.
The prevalence of diabetes mellitus has been increasing in recent decades in China, and vascular complication is the major burden in patients with type 2 diabetes. Previous studies demonstrated that only glycemic control was not effective enough to prevent or improve diabetic vascular complications, but guidelines from the Chinese Diabetes Society and other national guidelines recommend an integrated multifactorial treatment approach. In this study, we aim to evaluate the effect on diabetic vascular complications of a multifactorial intervention comprising behavior modification, polypharmacological therapy and periodical monitoring in patients with type 2 diabetes.
Psychosis is a heterogeneous disorder and present treatment only works for a limited number of patients. In order to identify new therapeutic targets, this study will longitudinally characterize the underlying pathologies in those with poor treatment response using complimentary brain imaging modalities.
The primary objective of this investigation is to compare the efficacy of two different AF ablation strategies in patients with non-paroxysmal AF: CPVI plus electrophysiologic substrate ablation in the left atrium during sinus rhythm (STABLE-SR) and CPVI alone.
As one of the essential micronutrients, selenium has important biological functions. However, an effective and convenient method for evaluation of selenium nutritional status has not yet been established. Previous literature has disclosed effect of selenium deficiency on inactivating glutathion peroxidase and deiodinase, which may cause decreased conversion from thyroxine ( T4) to triiodothyronine (T3). A case-control study is designed to demonstrate the association between selenium deficiency and abnormally elevated T4 or T4/T3, which may provide more clues for establishing effective selenium assesment methods.
The aim is to investigate incidence of HBsAg, anti-HCV in serum samples and evaluation of biomarkers taken from patients who were followed the intensive care unit of Sakarya University Training and Research Hospital and The intensive care unit attracts attention by making health workers more susceptible to the risk of hepatitis.
Data collection and observation of changes within AMD patients performing visual training on mobile devices
Primary end points: This clinical trial is aimed to analyze the effectiveness of Levonorgestrel-Releasing Intrauterine System (LNG-IUS, Mirena®) in the fertility-sparing treatment of atypical endometrial hyperplasia and early endometrial carcinoma, including pathology response and pregnancy outcome. Second end points: To analyze the appearances of side-effects.
Ulcerative colitis (UC) belongs to the group of inflammatory bowel disease (IBD) and is characterized by a chronic relapsing disease course. As uncontrolled intestinal inflammation can lead to severe disease complications, treatment of UC has evolved from sole treatment of symptoms up to histological remission which is marked by the absence of histological inflammation. To correctly assess and quantify the degree of histological inflammation in IBD patients remains difficult. Digital holographic microscopy (DHM) is a new imaging technique belonging to quantitative phase contrast imaging. It is based on the detection of optical path-length delays in a stain-free manner, thereby providing a refractive index which directly correlates to tissue density. This study aims to evaluate the role of DHM for quantifying the degree of histological inflammation in endoscopically acquired biopsies of UC patients in a prospective clinical trial. From 28 UC patients, the investigators will obtain endoscopically acquired colonic biopsies. The investigators will assess the degree of inflammation in these biopsies using DHM and in addition to this an experienced histopathologist will determine the degree of inflammation in these biopsies using a histological scoring system (Nancy-Score = goldstandard). Finally, the investigators will directly correlate the results from DHM analysis to the histological analysis using the Nancy-Score.
