Active clinical trials for "Syndrome"

The study will investigate the influence that extravascular lung water index (EVLWi) could have on the efficacy and persistance of efficacy of prone position in patients with acute respiratory distress syndrome. Prone position will increase blood oxygenation in 75% of the cases and will be persistant in half of the cases. Unfortunately, no clinical criteria has been found correlated with efficacy. The quantity of lung edema, with increased lung weight, could be a determinant factor of efficacy and the persistance of the efficacy. EVLWi, assessed with the PiCCO2 device, reflects the quantity of fluid accumulated in interstitial and alveolar spaces. The hypothesis is that patients with higher EVLWi will have less efficacy of prone position in oxygenation and also that the beneficial effects of prone position will last shorter compared to patients with lower EVLWi.

The purpose of this study is to make a dialectical classification of patients who will receive 131I treatment after operation of thyroid cancer from the point of view of dialectics of syndrome elements of traditional Chinese medicine. By observing the changes of TSH among patients with different syndrome types, investigators can better understand the reasons for the differences in TSH changes among patients. Thus, it provides a basis for putting forward the scheme of stopping taking levothyroxine before iodine treatment, improving the quality of life of patients after radical thyroidectomy, and providing reference for individualized guidance of the timing of radioactive iodine therapy for patients after DTC.

The pathophysiology of Irritable bowel syndrome (IBS) is multifactorial involving complex interplay of altered intestinal permeability, mucosal immune activation, visceral hypersensitivity and gut dysbiosis. Although the exact triggers for these pathological changes in IBS are not clear but diet might play an important role. In fact, several studies have reported improvement in gastrointestinal symptoms on a diet low in FODMAPs (LFD) in patients with IBS, specifically in diarrhea predominant IBS (IBS-D). However, the mechanism of action of LFD is not well understood.

The objective of this study is to evaluate the long term safety and efficacy of once weekly dosing of idurasulfase-beta 0.5mg/kg administered in Hunter Syndrome(Mucopolysaccharidosis II) Patients

To assess the efficacy of decitabine and identify predictors for response to decitabine therapy.

The sleep apnea hypopnea syndrome (SAHS) is a respiratory disorder characterized by frequent breathing cessations (apneas) or partial collapses (hypopneas) during sleep. These respiratory events lead to deep oxygen desaturations, blood pressure and heart rate acute changes, increased sympathetic activity and cortical arousals. The gold standard method for SAHS diagnosis is in-hospital, technician-attended overnight polysomnography (PSG). However, this methodology is labor-intensive, expensive and time-consuming, which has led to large waiting lists, delaying diagnosis and treatment. Blood oxygen saturation (SpO2) from nocturnal pulse oximetry (NPO) provides relevant information to detect apneas, it can be easily recorded ambulatory and it is less expensive and highly reliable. The investigators hypothesize that an automatic analysis of single oximetric recordings at home could provide essential information on the diagnosis of SAHS. The aim of this study is two-fold: firstly, the research focuses on assessing the reliability and usefulness of NPO carried out at patient's home in the context of SAHS detection and, secondly, the study aims at assessing the performance of an automatic regression model of the AHI by means of neural networks using information from NPO recordings. To achieve this goal, both PSG and NPO studies are carried out. A polysomnography equipment (E-Series, Compumedics) is used for standard in-hospital PSG studies, whereas a portable pulseoximeter (WristOX2 3150, Nonin) is used for ambulatory NPO. NPO is carried out the day immediately before or after the PSG at patient's home. Patients are assigned to carry out the NPO study before or after the in-hospital PSG randomly. In addition, in-hospital attended oximetry is also performed simultaneously to the PSG using the portable pulseoximeter.

The objective of the proposed study is to design and evaluate a touch screen computer based multi-factorial intervention to educate individuals at risk of Metabolic syndrome in diverse Indian settings including urban, rural and slum in the State of Bhubaneshwar. The study objective is to improve metabolic syndrome related knowledge, attitude and practices among individuals using the proposed interactive, bilingual computer based educational program.

The metabolic syndrome (MetS) is a cluster of clinical indices that signals increased risk for cardiovascular disease and Type 2 diabetes. Women with polycystic ovary syndrome (PCOS) were associated with MetS and insulin resistance. Cluster analysis was a useful tool for identifying groups of women sharing similar metabolic risk factor patterns. Oligomenorrhea, hyperandrogenism and polycystic ovary morphology were the three major components of PCOS. Obesity is a main risk factor in metabolic syndrome. the investigators are interesting to evaluate the relationship between risk of metabolic syndrome and their clinical and/or biochemical characteristics in women with reproductive age. Design: Retrospective study; medical records reviewed. Participants and setting: The investigators retrospectively reviewed the medical records of female patients who visited our Reproductive Endocrinology Clinic from Jan. 1, 2009 to Jun. 31, 2012.

This is a prospective observational study to determine the reliability and accuracy of Near Infrared Spectroscopy (NIRS) to detect oxygen flow in the extremities of injured and non-injured soldiers over time. This technology may be useful in the detection of acute compartment syndrome. We hypothesize that: NIRS values will be well-correlated with intracompartmental pressure measurements NIRS values will be significantly different between non-injured and injured extremities, and injured extremities treated with fasciotomy for acute compartment syndrome. NIRS values of the upper extremity and feet will correlate to values from normal legs in critical control patients and patients with unilateral sever lower extremity injuries.

Obstructive Sleep Apnea (OSA) is associated with increased oxidative stress. The major sources of Reactive Oxygen Species (ROS) in the vasculature are the NADPH oxidases. Several polymorphisms related to NADPH oxidase expression or NADPH oxidase activity has been identified. The investigators are going to compare the distribution of the allelic frequencies of A-930G and C242T polymorphisms and their possible relationship with the levels of 8-isoprostanes as a marker of oxidative stress in patients with OSA and in a control group without OSA.
