Active clinical trials for "Syndrome"

The link between metabolic disturbances and vitamin D receptor (VDR) and MEGALIN (or LRP2) gene polymorphisms remains unclear, particularly among African-American adults. The associations of single nucleotide polymorphisms (SNPs) for VDR [rs1544410(BsmI:G/A), rs7975232(ApaI:A/C), rs731236(TaqI:G/A)] and MEGALIN [rs3755166:G/A,rs2075252:C/T, rs2228171:C/T] genes with incident and prevalent metabolic disturbances, including obesity, central obesity and metabolic syndrome (MetS) were evaluated. From 1,024 African-Americans participating in the Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS, Baltimore, MD, 2004-2013) study, 539 subjects were selected who had complete genetic data as well as covariates selected for metabolic outcomes at two consecutive examinations (visits 1 and 2) with a mean follow-up time of 4.64±0.93y. Haplotype (HAP) analyses generated polymorphism groups that were linked to incident and prevalent metabolic disturbances.

To compare clinical outcomes in patients with chronic kidney disease (CKD) presenting with an acute coronary syndrome (ACS) treated with clopidogrel or ticagrelor (both FDA approved and guideline indicated drugs for treating these patients upstream managed medically or with coronary revascularization).

In approximately half of individuals with Down syndrome, an higher than normal number of vessels cross the optic disc margin. Investigator hypothesize that early retinal vessel branching occurs due to inhibition of angiogenesis by triplet overexpression of endostatin, an angiogenesis inhibitor encoded on chromosome 21. Since angiogenesis is critical in the development of eyes and other organs angiogenesis depended (specially kidney, brain, and recently described lungs and heart), early branching of retinal vessels at the level of the optic disc would also likely result in abnormal renal and other organs development in these individuals. Investigator wish to determine whether observation of optic disc vessels may serve as an indicator of elevated endostatin levels and other angiogenesis-dependent organs anomalies.

The Investigators will measure if hepatic metabolism is upregulated in obese girls with PCOS and hepatic steatosis (HS), compared to PCOS without HS and obese controls without HS.

The study on evaluation the pattern of TD in MetS population may help us to know the magnitude of overlap of these two disease entities and may highlight the importance of thyroid function tests in patients with MetS. This can lead to proper planning and adequate management strategies, resulting in significant reduction in cardiovascular morbidity and mortality due to MetS with TD. Thus, this study aims to evaluate the pattern of TD in patients with MetS and to explore the relationship between TD and components of the MetS.

Randomized, placebo controlled clinical trial that evaluate the role of taking metformin therapy during pregnancy in women with polycystic ovarian syndrome(PCOS) in reducing the development of gestational diabetes(GDM) and improving pregnancy outcomes.

The game Marble Maze Classic® will be used, in which the participants have to move the mobile phone to conduct a virtual marble through a maze design. The investigators will evaluate 100 individuals (50 with Down Syndrome-DS and 50 with typical development-TD) and divide both with DS and TD into group 1 and 2, where each group consists of 25 participants, with group 2 using a maze design totally opposite to group 1.

This studies´ objective is to describe how different PEEP levels affect dead space measured by Bohr´s formula.

Irritable bowel syndrome is common. Currently, it is a diagnosis of exclusion. There is increasing evidence of the importance of the microbiota in the pathophysiology of this disorder. However, it has been challenging to measure the "activity" of the microbiota in vivo as much of the GI tract is inaccessible. Fermentation by the microbiota occurs in the colon, a by product of which are short chain fatty acids. Measuring pH in the colon could potentially act as a surrogate marker of fermentation. The investigators are undertaking a randomised controlled trial in patients with IBS measuring the pH in the digestive tract using a wireless motility capsule at baseline and in response to dietary changes in patients with diarrhoea predominant IBS and in response to linaclotide in those with constipation predominant IBS to ascertain the effect of these interventions on the microbiota and clinical outcomes.

The hypothesis of the study is that individuals with poor pulmonary function secondary to TIS will benefit from expansion thoracoplasty. The investigators specific aims are to: Record pulmonary function and thoracic volume of TIS patients at enrollment and with serial observation Offer expansion thoracoplasty therapy to TIS patients with poor pulmonary function at enrollment progressive decline in pulmonary function progressive chest wall and/or spinal deformity lack of appropriate increase in thoracic volume during growth Document efficacy of expansion thoracoplasty for TIS patients
