Filter by:Pilot study on molecular quantitation and sequencing of endometrial cytokines gene expression and their effect on the outcome of in-vitro fertilization (IVF) Cycle
The purpose of this study is to collect long-term safety and efficacy data for participants treated with ibrutinib and to provide ongoing access to ibrutinib for participants who are currently enrolled in ibrutinib studies that have been completed according to the parent protocol, are actively receiving treatment with ibrutinib, and who continue to benefit from ibrutinib treatment.
The specific aim is to compare the effectiveness of Off-the-Shelf splints and splints provided by Occupational Therapy for treatment of trapeziometacarpal (TMC) arthrosis.
The purpose of this study is to assess the effects of Chinese medicine Shansong Yangxin capsule for sinus bradycardia complicated with ventricular premature beats.
This is an observational research study whose purposes are to see the effects of repeated hyperbaric oxygen therapy treatments on the levels of stem/progenitor cells in peripheral circulating blood following five days of treatment, 90 minutes per day at 2.0 atmospheres absolute in 100% USP Grade Oxygen. Hyperbaric oxygen has a greater oxygen concentration than air at sea level. In this research, the concentration of oxygen will be twice the level of oxygen at sea level.
The purpose of this study is to compare two regimens of low volume (2L) polyethylene glycol(PEG)plus ascorbic acid versus standard volume (4L) PEG alone for bowel preparation in out-patients
The primary objective of the study is to assess the efficacy of Digestive Enzyme Blend #2, a digestive enzyme dietary supplement product, on markers indicative of inflammation after a meal. The markers will be assessed by blood levels tumor necrosis factor alpha (TNF-alpha), interleukin-1 beta (IL-1beta), interleukin-6 (IL-6), and high sensitivity C-reactive protein (hsCRP) at times 0, 45 minutes, 2 hours and 4 hours post-meal. A full complete blood count (CBC)and an erythrocyte sedimentation rate (ESR) blood test will also be conducted at times 0 and 4 hours post-meal. In addition, a questionaire on Gastrointestinal symptoms will be administered 4 hours post-meal. The study hypothesis is that some or all of these potential markers of inflammation will increase following the meal, and the amount of increase in inflammation will be attenuated when a digestive enzyme is consumed with the meal compared to the placebo. In addition, it is hypothesized that levels of gastric discomfort as assessed by the questionaire will be reduced with the digestive enzyme compared to the placebo.
Pulmonary hypertension (PH) is a life-threatening cardiovascular disease characterized by pathological elevation of mean pulmonary arterial pressure (mPAP) >/= 25 mmHg at rest. mPAP < 20 mmHg is defined as normal, values in the range between 21-24 mmHg are described as "borderline PH" diagnosed by right heart catheterization. Based on the etiology, PH is assigned to 5 groups (WHO, Data Point, 2008), whereas classification of disease is an important prognostic and therapy-deciding criterion. Cardiac magnetic resonance tomography (CMR) provides a reliable technique to estimate elevated mean pulmonary arterial pressure from period of existence of a vortical motion of blood flow in the main pulmonary artery. Vortex can be visualized in 3-dimensional vector field, particle trace and streamline representations and can be analysed with respect to vortex related measures (geometry of center, vortex formation, vorticity, propagation dynamics …). Furthermore T1-mapping and non-contrast enhanced lung perfusion/ventilation scans represent promising techniques for PH characterization. Aim of this explorative study is to 1. analyse PH-associated blood flow characteristics in the heart and the surrounding great vessels with respect to the 5 groups of PH, and 2. investigate the hemodynamic state of "borderline PH" compared to normal mPAP and manifest PH by non-contrast CMR.
Partners HealthCare maintains a Patient Data Registry (PDR) with information from all patient encounters at Partners HealthCare facilities. We intend to utilize the PDR to identify groups of patient who are of high clinical suspicion for undiagnosed lysosomal acid lipase deficiency. A group of potential participants will be identified through the PDR. Detailed records will be requested to further narrow to ideal participants based upon previously existing diagnoses and symptoms. Participants will be invited to partake in the study via a letter from their Partners care provider with supporting study details. Study participants will be evaluated in a one-time visit. A complete family and medical history will be collected. A physical exam will be performed, and up to 20cc of blood will be drawn. All participants will be notified of their disease status via letter and phone call from the study staff. If the study participant is diagnosed with LALD through this evaluation, proper follow-up recommendations and referrals will be provided. Our intent is to determine if existing patient data can successfully be utilized to aid in the identification of patients with rare genetic disease.
The aim of this study is the comparison between the effects of supplementation with 25000 IU preformed vitamin A (retinyl palmitate)on retinoic acid receptor and retinoic x receptor expression.
