Active clinical trials for "Syndrome"

The aims of the study is to assess the diagnostic utility of home respiratory polygraphy (HRP) complemented with polysomnography (PSG) in childhood Obstructive Sleep Apnea-Hypopnea Syndrome (OSAS), as well as its usefulness in the therapeutic decisions. Methods: Children referred with suspected OSAS will be evaluated during one year performing home respiratory polygraphy in all cases. PSG will be chosen in patients with concomitant pathology or according to medical criteria, or complemented with HRP in doubtful cases. Clinical and anthropometric data, severity, technical quality and treatment will be obtained. Patients will be divided in two groups (HRP vs PSG) and compared, and the accuracy from HRP to establish a therapeutic decision it wil calculated. The investigator's hypothesis is that PSG should be recommended only for complex or doubtful cases.

The aim of this study is to conduct survey-based assessments for the safety of air travel in patients with Birt-Hogg-Dube syndrome (BHD). The study will enroll patients through the clinic network at Rare Lung Disease Consortium (RLDC) and through the BHD foundation website. Patients will have access to the questionnaire via REDCap (an online data management system) and each patient will be provided with a link to complete the survey. The investigators plan on enrolling approximately 100 patients with BHD for the purpose of this study. Secondary aims of this study include further characterization of the clinical aspects of disease and to establish a contact registry for these patients, in order to facilitate future studies.

Familial hypercholesterolemia (FH) is a most prevalent genetic disorder, defines as high cholesterol level and premature death. The prevalence of FH has been reported in few countries however unknown in Iran. Thus recognize the FH patients, determine the diagnostic strategies and appropriate treatments are important. Also acute coronary syndrome (ACS) is a group of conditions which arises from reduction of blood flow in coronary arteries. Three specific conditions are included: ST elevation myocardial infarction, non ST elevation myocardial infarction and unstable angina. Premature ACS defined by occurrence of ACS<55 for men and ACS<60 for women. Studies demonstrated direct connection between familial hypercholesterolemia and occurrence of premature ACS. Investigators intent to detection of FH amongst patients with acute coronary syndrome.

The hypothesis of this study is that reductions in body weight could improve inspiratory muscle function attenuating the inspiratory metaboreflex in metabolically healthy obese individuals and obese individuals with metabolic syndrome.

This study aims to determine whether or not early spirometric detection and management of obstructive lung disease with combined fluticasone/azithromycin/montelukast therapy (FAM) can attenuate declining lung function, prevent the development of bronchiolitis obliterans, and improve patient outcomes following hematopoietic stem cell transplant.

A pilot, prospective, comparative study. To include both male and female patients who have presented an ischaemic stroke (full stroke or TIA) or an ACS, 5 to 30 days prior to inclusion. The proposed study aims to investigate and analyse the differences in functional and structural arterial properties between the patients who presented an ischaemic stroke and those who presented ACS. The hypothesis is that the patients in both groups will present differences partly in terms of their "traditional" cardiovascular risk factors, but also in terms of their arterial properties. All of the confounding factors studied (cardiovascular risk factors, treatments) will be taken into account in order to explain the differences in the arterial properties found between the two groups. Furthermore, the prevalence of signs and symptoms in the two populations will be studied.

Healthy women and women with breast cancer have been enrolled in our nested case-control study between 2008 and 2009 in order to evaluate the association between metabolic syndrome and breast cancer, analyzing anthropometric parameters blood pressure, assessing serum HDL-C, triglyceride, fasting plasma glucose, insulin, testosterone and uric acid levels and administering a questionnaire about physical activity, food intake, tobacco use, alcohol abuse, personal and familial history of disease. Our data support the hypothesis that metabolic syndrome may be an indicator of breast cancer risk in postmenopausal women. The change of the hormonal arrangement in postmenopausal, along with an increase in visceral adiposity, probably favour the hormone dependent cell proliferation, which drives tumorigenesis. Adjustments in lifestyle with physical activity intensification and healthy diet may represent modifiable factors on which sporadic breast cancer primary prevention may work on.

Background: Both prasugrel and clopidogrel are prescribed drugs which compete as platelet inhibitors in patients with acute coronary syndrome (ACS). Whether rates of drug resistance/hyporesponsiveness are lower with prasugrel and whether more consistent and earlier onset of platelet inhibition may reduce infarct size in patients with ACS undergoing early PCI remains, at present, unknown. Study design/study population: This trial is a prospective, open-label, single centre observational trial. Patients receive either prasugrel (60mg) or clopidogrel (600mg) at the discretion of the attending cardiologist. Patients with exclusion criteria for prasugrel will be excluded for clopidogrel as well. The study population includes 80 subjects with moderate to high-risk ACS, ie patients with unstable angina (UA) and non-ST-segment elevation MI (NSTEMI) and TIMI risk score of 3 or higher, within 72 hours after onset of symptoms. In all patients early PCI is planned. Study objective/endpoint/methods: The primary objective of this trial is to evaluate whether rates of hyporesponsiveness are lower with prasugrel and whether more consistent and earlier onset of platelet inhibition may reduce infarct size in ACS in patients undergoing early PCI. The primary endpoint is the rate of drug resistance at time of index intervention. Optical and impedance aggregometry using ADP (5 and 20 μM) and collagen (1 μg/ml) as platelet agonists is used to measure platelet aggregation. Addition of the specific antagonists aspirin and mesamp to the probe is used to discriminate between pharmacodynamic and pharmacokinetic drug resistance. Secondary endpoint is the reduction of myocardial infarct size determined by post-interventional increase of high sensitive TnT (TnT hs) during the days following the index event reflecting earlier, more effective and more consistent inhibition of platelet function. Tertiary endpoint is the composite clinical endpoint of cardiovascular death, nonfatal MI, or stroke and urgent target vessel revascularization during hospitalization and after 6 and 12 months. Safety endpoint is any TIMI major or minor bleeding during hospital stay and after 6 and 12 months including intracranial and life-threatening bleeding.

Mechanisms that link metabolic syndrome to atherosclerosis are incompletely understood. As a part of Hämeenlinna Metabolic Syndrome Research Program (HMS) surrogate indicators for atherosclerosis are studied in 120 men with metabolic syndrome, 120 men with coronary heart disease and 80 physically active controls and in different settings.

The aim of the study is to examine the kinetic, anti-oxidant, anti-inflammatory and cellular cholesterol efflux properties of high-density lipoprotein (HDL) in subjects with the metabolic syndrome (MetS) and lean individuals.
