Active clinical trials for "Syndrome"

The aim of the study is to compare the intubation conditions among propofol and remifentanil versus midazolam and remifentanil in premature neonates with respiratory distress syndrome. At the same time, to show the group of drugs that could let the neonates with no residual sedation after the use of surfactant (the possibility of the premature neonates to be readily extubated after the use of surfactant).

Background: Infertility affects up to 15% of married couples. About half are attributable to female factors, among which anovulation is the leading cause. Some 5% of all women of reproductive age are anovulatory due to the polycystic ovarian syndrome (PCOS). PCOS causes also major health and cosmetic problems and significantly affects quality of life. PCOS is associated with cardiovascular morbidity and Type 2 diabetes mellitus, but it is unclear whether these are caused by the ovarian dysfunction or result from a common denominator. Working hypothesis and aims: Whole genome analysis of multigenerational families in which at least one woman is affected by PCOS may significantly reduce the numbers needed to verify the specific genes, involved in the causation of PCOS. Methods: Registration of multigenerational families and production of personal files with full workup for the presence of PCOS or its absence (in the women participants). Drawing of blood, extraction and preservation of DNA. Analysis of all informative SNPs in the genomes of the participants on a specific microarray chip. Statistical analysis of the results. Expected results: Verification of the loci and putative genes, associated with the appearance of PCOS. Importance: Elucidation of the specific genes underlying the pathology of PCOS. Probable implications to Medicine: Paving the way for targeted treatment of the problems, associated with PCOS, based on the clear knowledge of its underlying cause(s).

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.

Bone marrow failure syndromes (BMFS) are rare disorders characterized by dysfunctional hematopoietic stem cells, which give rise to all red and white blood cells. The deficiency of blood cells, or cytopenia, caused by this malfunction leads to an assortment of diseases and disorders, all of which are characterized as BMFS. Because these diseases are rare, conducting research on them is difficult, and standards of treatment for most BMFS have yet to be developed. This study will collect clinical and laboratory data from people with BMFS to identify the characteristics and biological markers associated with these diseases over time. This information will assist doctors and researchers to develop better therapies and diagnostic tests that will help improve the management of BMFS and cytopenias.

RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is looking at blood samples in young patients with cytopenia after undergoing a donor stem cell transplant.

Diabetes is prevalent in schizophrenics and may be induced by antipsychotic treatments. Several retrospective studies have suggested that psychiatric patients exposed to atypical antipsychotics may be at a higher risk for developing diabetes and ketoacidosis. The association between these atypical antipsychotics and the onset of diabetes is further strengthened by observations of: the time sequence between the initiation of antipsychotic treatment and the onset of diabetes; remission after the discontinuation of medications; and re-emergence of diabetes following the re-introduction of atypical antipsychotics. The treatment emergent diabetes, along with other metabolic disturbances, represents a serious issue in the use of atypical antipsychotics. Major current debates and unresolved research issues which are also the focus of this proposal, are: schizophrenia per se, versus the use of antipsychotics, in triggering diabetes; whether there are differences between "typicals" and "atypicals" in such an effect; whether there are differences among different "atypicals"; whether, and to what extent, treatment emergent diabetes may be associated with, or independent of, weight gain, which also often is associated with the use of antipsychotics; and genetic and environmental risks in association with treatment emergent diabetes. The policy of some hospitals in Taiwan that discourages the use of atypical antipsychotics for new onset schizophrenia directs the investigators to a study design looking at the associated diabetes of both types of antipsychotics. Such a design may provide some hints to the unresolved research issues mentioned above. Meanwhile, a broader defined term, X-syndrome, or metabolic syndrome, is being used to describe the diabetic condition associated with antipsychotics. X-syndrome is a risky condition leading to cardiovascular diseases and diabetes, with insulin resistance as the major outcome, associated with two of the following conditions: truncal obesity (deposited in the thorax and abdomen, instead of the hips and thighs), high triglycerides, high low-density lipoprotein (LDL) cholesterol or hypertension. The proposed study will combine the phenotypes of diabetes and X-syndrome to explore the abnormal metabolism caused by antipsychotics, bridge important information gaps, and provide data contributing towards a better understanding of the risk and management of diabetes and X-syndrome associated with the use of antipsychotics. Three assessment tools, namely the Clinical Global Severity (Clinical Global Impressions - Severity) or the Positive and Negative Symptom Scale (PANNS), the Diabetes Risk Assessment (ADA) and the Life Style Survey, together with physical measurements, collect additional information for this study. Diabetes related biochemistry, including glucose, insulin, leptin, lipids and glycohemoglobin, will be measured to form a composite phenotype for further pharmacogenetic studies. Candidate genes involved in pancreatic beta cell insulin secretion will be examined in priority to see if they play a role in the development of the antipsychotics-induced diabetes.

Polycystic ovary syndrome (PCOS) phenotype can be structured into three components: anovulation, hyperandrogenism and the metabolic syndrome (of which hyperinsulinemia, secondary to insulin resistance, is the central abnormality)(1). It is the most common endocrinologic disease seen in Gynecologic clinic. The follicular excess in polycystic ovaries and the failure of selection of one dominant follicle contribute to the anovulation of PCOS. The infertile PCOS female usually suffered from difficult ovulation induction and high risk of ovarian hyperstimulation syndrome because of extensive stimulation. PCOS is the main androgen disorder in women and has been suggested to be associated with a high risk of developing cardiovascular disease and type-2 diabetes. In many PCOS patients, overweight or central obesity is generally associated with increases in fasting insulin levels, insulin resistance, and glucose intolerance, and has been identified as a target for new therapeutic strategy, including early change in lifestyle. Insulin resistance, defined as decreased insulin-mediated glucose utilization, is commonly (10-25%) found in the normal population. In women with PCOS, insulin resistance appears even more common (up to 50%), in both obese and non-obese women.Hyperinsulinemia appears to play a key pathogenic role in the ovarian androgen overproduction, because of the stimulatory effect of insulin on ovarian steroid production.

This study was designed as retrospective chart review to test our hypothesis whether there are the differences in inflammatory and anti-inflammatory mediators between asthmatic and ACOS patients with small airway obstruction, and COPD

Studies have shown that the risk of developing heart arrhythmias, is increased in patients receiving medication for Attention-deficit hyperactivity disorder (ADHD) and depression. The QT-interval on a electrocardiogram (ECG) is often used to assess the patients risk of developing heart arrhythmias. The QT-interval defines the hearts electrical resting period and a long interval is linked to an increased risk of developing heart arrhythmias. In this project the investigators wish to examine possible side-effects in patients receiving medication for ADHD and depression and their dynamic QT-interval changes, by analysing the ECG changes that occur during "Brisk Standing".
