Currently Transfusion-related acute lung injury (TRALI) is the leading cause of transfusion-related mortality in the United States, and one of major post-transfusion complications. TRALI is defined as new ALI occurring within 6 hours from the onset of transfusion. It is manifested by acute dyspnea, hypoxemia and bilateral infiltrates in chest radiograph. TRALI may be caused by any blood product and is not dose-dependent. Associated risk factors include prolonged storage of blood products and underlying conditions such as severe IHD hematologic malignancies or active infections. Since TRALI has only recently been defined as a clinical entity, and its prevalence has been largely underestimated - the epidemiology of TRALI is not well established. Therefore the objective of this work is to study the incidence of TRALI in a patient population that receive blood products frequently, namely orthopedic-oncologic.
The purpose of this study is to determine whether relaxation and guided imagery techniques are effective in reducing childbirth pain.
Hypoestrogenism, common in menopause, is responsible for systemic and metabolic changes affecting women's wellness, favoring hot flashes, urogenital atrophy and bone mass loss. Hormone reposition therapy (HRT) with estrogen or estrogen associated to progesterone is administered to minimize these effects. Meanwhile, the beneficial effects of HRT are known, there is still concern about its adverse effects such as thromboembolic and cardiovascular effects, increased risk of breast and endometrial cancer. Thus, there is an increasing interest in the development of phytohormonal HRT. The aim of the investigators' study is to evaluate the effects of concentrated extract of soy on hypercoagulation markers in menopausal women.
Assessment of biochemical and sonographic marker to predict the risk for developing preeclampsia Among biochemical markers are serum level of Placental Protein 13 (PP13) and Placenta Growth factor (PIGF). For sonographic marker Doppler pulsatility Index of the blood flow through the uterine maternal arteries is assessed. PP13 is produced by the placenta and released to the maternal blood circulation. It has been shown to be an effective serum marker for early onset preeclampsia (Nicolaides KH et al., 2005). The purpose of this study is to combined the assessment of the biochemical markers with Doppler in the first and the second trimester to provide a comprehensive evaluation of various methods for sequential and combined analysis to assess the risk for developing preeclampsia.
This study will use the licensed HPV vaccine, Gardasil, as a surrogate for an HIV vaccine, in order to explore some of the ethico-legal,psycho-social and logistical challenges involved in running an HIV vaccine trial in adolescents.
The achievement of high local concentration of Eptifibatide, a GP 2b3a inhibitor,via direct intracoronary injection, promotes (in vitro) clot disaggregation. It remains unclear if it is of superior benefit than the routine intravenous administration of these agents. In patients presenting with acute myocardial infarction, and undergoing primary coronary intervention, intracoronary administration of Eptifibatide may increase local drug concentration by several orders of magnitude and promote clot disaggregation with a minimal increase in systemic drug concentration, and in that way enhancing myocardial perfusion and survival.
Pediatric patients, during their illness often treated with furosemide (Lasix) continuous drip, often, with dosages above 4-6mg/kg/day (the recommended dose). This study will monitor hearing status of these children prior to their therapy with furosemide, during this therapy and after.
The purpose of this study is to evaluate a scoring tool to help determine the presence of Heparin Induced Thrombocytopenia (HIT), which is an adverse reaction to heparin. We hypothesize that this scoring tool will be very useful in excluding patients who are suspected of having HIT.
The aim of this study is to develop an algorithm to automatically detect falls and near falls, in the elderly and in Parkinson's Disease patients. Subjects will arrive at the investigators' gait laboratory for assessment. A sub-group of the subjects, will receive a monitoring device, to be worn at home for three days.
The purpose of this research study is to determine if participation in a fifteen week introductory exercise regimen using the NuStep by sedentary adults diagnosed with Type 1 or Type 2 diabetes will affect exercise adherence and lifestyle adjustment. This study will examine if using the NuStep encourages participants to seek other modes and facilitates interest in exercise. Age, gender, weight, height, waist-to-hip ratio, heart rate, blood pressure, 6-minute walk test, and A1C will be recorded pre, mid-point, and post-test. During each NuStep exercise session heart rate, blood pressure, blood glucose level, oxygen saturation, METs, and the Borg rate of perceived exertion will be monitored. Associations between NuStep use and exercise adherence are investigated through the following hypothesis and null hypothesis. There is an association between using the NuStep as an introductory exercise regimen by sedentary adults diagnosed with Type 1 or Type 2 diabetes and exercise adherence. The null hypothesis states there is no association between using the NuStep as an introductory exercise regimen by sedentary adults diagnosed with Type 1 or Type 2 diabetes and exercise adherence. The primary endpoint of the study is the qualitative measurement, by use of a questionnaire, of attitude and interest toward exercise in participants by assessing if they choose to seek and perform other modes of exercise. Secondary endpoints are the quantitative measurement of the change in weight, waist-to-hip ratio, heart rate, blood pressure, 6-minute walk test, and A1C levels.
