Active clinical trials for "Metabolic Diseases"

In vivo confocal microscopy (IVCM) has been used in clinical settings for more than 25 years, and is noninvasive, rapid and easily repeatable technique to investigate ocular surface disorders. It enables morphological and quantitative analysis of ocular surface microstructure. [1-3] As the technology advances, new IVCM machine, Heidelberg Retinal Tomograph with Rostock Corneal Module (HRT-RCM), was developed. Hardware and software modifications and acquisition techniques continue to expand the applications of the HRT-RCM for quantitative in vivo corneal imaging at the cellular level. The new software can access the corneal nerve more accurate. Here the investigators proposed this Institutional Review Board (IRB) to collect healthy persons and cases of different systematic diseases as well as etiologies of ocular surface diseases.

To develop machine learning algorithms for the identification of future development of cardiovascular and metabolic disease

Our goal is to demonstrate the feasibility of laying uncomplicated ultrasound-guided central subclavian catheter by supraclavicular route in the newborn.

The overall objective of this study is to investigate in depth the nature of metabolic physiology, body composition and epigenetic differences of the different phenotypes of overweight and obese individuals who are otherwise overtly healthy among the three major ethnic groups in Singapore.

Study of the intermediate metabolism in children diagnosed with ALL compared to healthy matched controls.

Cardiac ischemia is a common pathological condition, known to elicit multiple pathological processes at the cellular level. One of the most affected is thought to be cellular metabolism, key for the adequate cardiac function. The aim is to study mitochondrial bioenergetic function, interaction with other cellular systems and influence of several co-morbidities in myocardium of the affected patients.

Bariatric surgery is well established method of treating patients with obesity. Obesity is well-documented risk factor for many health conditions including some cancer, cardiovascular diseases, pulmonary diseases and type-2 diabetes. Bariatric surgery is associated with improved comorbidities, quality of life and survival in severe obesity. However, the rate of conversion or revisional bariatric surgeries is increasing nowadays. Recent date estimate the rate of revisional procedures between 8-25% of all bariatric surgeries performed worldwide. Weight recidivism or fail to achieve a significant weight loss (estimated 10-20% of operated patients) remains a challenge for surgeons and patients. This has economic and health implications, leading to reduction in quality of life and increased prevalence of obesity-related comorbid conditions. Therefore, the aim of this study is to identified patients with failure after primary bariatric procedure in population of Poland.

In chronic kidney disease calcium (Ca) and phosphate (P) metabolism disorders are very common and also they are one of the leading causes of morbidity in these population. FGF23 is a novel factor that contributes Ca-P disorders. It has been hypothesized that FGF 23 increase is mediated by asymmetric dimethylarginine (ADMA). The aim of the study is to evaluate this hypothesis.

This clinical study will investigate Jejunal Microbiota in Metabolic Diseases (Je-MiMe, n=45) and Colonic mucosa-associated Microbiota in Metabolic Diseases (Col-MiMe, n=45). Each cohort (Je and Col -MiMe) is composed of three groups: participants with obesity (n=15) with obesity and with type II diabetes (n=15). This research protocol is organized in two parts. Each part of this study will recruit 45 participants that are only recruited in one of the parts of the protocol (JE-MIME or COL-MIME). Thus, in total, the study will include 90 patients. Each part of this study is composed of 3 groups: 1) "Control Group ", 2) Obese group (Ob), 3) Obese and Type 2 Diabetes group (ObD). Control groups for part I (JE-MIME) and part 2 (COL-MIME) are composed of different participants. Each group is composed of 15 human adult volunteers for the JE-MIME study (part 1) and 15 participants for the COL-MIME study (part 2). Total number of participants is 45 for part 1, and 45 for part 2. Total number for this project is 90. Microbiota wil be collected during an endoscopy or coloscopy which is planned as routine care for the patients. Primary objectives are to characterize jejunal (JE-MIME, Part I of the study) and colonic mucosa-associated microbiota (COLMIME, Part II of the study) and compare both microbiota to faecal microbiota (evaluate differences and similarities between jejunal microbiota or mucus-associated microbiota and faecal microbiota). Secondary objectives are to 1) Correlate microbiota with metabolic health and inflammatory markers; 2) Correlate microbiota with lifestyle and neuropsychological health. Both the jejunal microbiota and mucus-associated microbiota are strong integrators of nutritional environment and intestinal health status, respectively, compared to the fecal microbiota. This study will help to better understand the physiopathology of metabolic diseases. This research could lead to finding specific microbiota members, either from the jejunal compartment or from the inner mucus layer, crucial for the promotion / protection of chronic intestinal inflammation and associated metabolic health.

This study is focused on measuring mitochondrial activity of human brown adipose tissue. During surgery, adipose tissue biopsies from white and brown adipose tissue will be collected from the deep neck area. These biopsies will be used to examine mitochondrial function via histological analysis, biochemical analysis and in vitro experiments based on precursor cells present in the biopsies.
