Active clinical trials for "Syndrome"

This is a prospective clinical study designed to procure blood samples from patients who present to the Emergency Department with suspected ACS (Acute Coronary Syndrome). Subjects enrolled in this study will sign and informed consent and have 4 blood samples drawn at different time points during their emergency department visit. In addition, data will be collected about the patient's health history, hospital procedures, and final diagnosis. The enrolling center will also contact the patients at 30-days, 3 months and 6 months to inquire about their condition and survival. Blood samples collected in this study will be sent to the sponsor organization for long-term storage and analysis in the future for novel blood markers as they become available. No genetic testing will be conducted on these samples.

The research project addresses the following hypotheses (A) the normal balance of beneficial and detrimental commensal intestinal bacteria is deranged in IBS, with selective alterations in clinically defined patient subsets i.e., diarrhea predominant IBS (D-IBS) and post-infectious IBS (PI-IBS); (B) these changes in intestinal microflora are associated with sub-clinical mucosal inflammation and activation of the mucosal immune system; and (C) activation of the mucosal immune system leads to alterations in gastrointestinal (GI) functions (i.e., motility and sensation) and functional symptoms.

The purpose of this study is to provide Decitabine to patients with Myelodysplastic syndrome (MDS) of all FAB (French-American-British) subtypes and Intermediate-1, Intermediate-2, and High-Risk International Prognostic Scoring System groups, including both previously treated and untreated patients.

Rett syndrome (RTT) is an X-linked severe neurodevelopmental disorder. Despite their good appetite, many females with RTT meet the criteria for moderate to severe malnutrition. The pathological mechanism is barely understood. Although feeding difficulties may play a part in this, other constitutional factors as altered metabolic processes are suspected. Irregular breathing is a common clinical feature, reflecting the immaturity of the brainstem in RTT. The primary pathophysiology is a defective control mechanism of carbon dioxide exhalation that leads to chronic respiratory alkalosis or acidosis. We assume that chronic respiratory acidosis or alkalosis causes derangement of the metabolic equilibrium in RTT females with important nutritional consequences. The aims of this pilot study are to describe the nutritional status of the RTT girls and to examine the consequences of a chronic respiratory acidosis or alkalosis on metabolic processes as a possible cause of impaired nutritional status.

The aim of this study is in a prospective, consecutive series of diabetic patients with carpal tunnel syndrome, who are then age and gender matched with non-diabetic patients having idiopathic carpal tunnel syndrome to compare the clinical results after carpal tunnel release.

Contribute to support hypothesis of relationships between genes involve in oncogenesis and those involve in embryological development.

The study will examine the sensitivity and specificity of a circulating cell-free nucleic acid test (DNA/RNA) to identify Down syndrome between about 10 weeks and 21 weeks 6 days gestation. In addition, the new test may be used to identify trisomy 13 and 18 as part of a more complete laboratory developed test. We hypothesize that the new circulating cell-free fetal NA-based test will accurately and precisely measure specific fetal markers in maternal circulation and that measurement will lead to the ability to noninvasively identify with high sensitivity and specificity, fetal chromosome abnormalities, such as Down syndrome.

The purpose of the study is to determine whether anticoagulant use (i.e. salicylates, clopidogrel, low-molecular weight heparin, or coumarin derivates) is able to prevent the development of the sinusoidal obstruction syndrome secondary to oxaliplatin-based neoadjuvant chemotherapy in patients suffering from colorectal liver metastases.

The overall goal of this study is to determine whether variations in the perilipin, and several other, genes would be a useful tool for physicians who are caring for morbidly obese patients to guide therapy. The main hypotheses to be tested is that sequence variations (polymorphisms) in the perilipin gene and several other obesity-related genes are associated with resistance to weight loss for obese individuals on energy restricted diets, potentially playing a role in the development of obesity related complications.

This is a registry of patients with non ST segment elevation Myocardial Infarction (heart attack) and/or unstable acute coronary artery syndrome treated with a standardized protocol including Bivalirudin. Data will be collected on diagnosis, treatment and outcomes.
