This is an observational study assessing patient satisfaction following at least 5 years of BOTOX® treatment for glabellar lines.
The purpose of this study is to evaluate the 24-hour spirometry effect (FEV1) of Fluticasone Furoate/Vilanterol Inhalation Powder 100/25mcg once daily compared with tiotropium bromide inhalation powder 18mcg once daily over a 12-week treatment period in subjects with COPD who have or are at risk for co-morbid cardiovascular disease
The investigators propose a screening population-based study to systematically evaluate the accuracy and clinical relevance of sDNA testing as a potential alternative to colonoscopy screening. In addition, the investigators propose a genetic epidemiologic study of the relation between colon polyps, an established precursor of colon cancer, and two factors that may influence risk for colon cancer: candidate genes and diet.
The purpose of this study is to determine the efficacy of the Heart Failure Exercise and Resistance Training (HEART) Camp behavioral exercise training intervention on long-term adherence to exercise at 18 months in patients with heart failure. The central hypothesis is that the HEART Camp intervention group (HC) will have significantly better adherence to exercise at 18 months.
Zambia recently introduced routine infant immunization against rotavirus - the most important cause of severe gastroenteritis and diarrhoea mortality in children. Although vaccines like Rotarix are a cost effective tool against infectious diseases, live oral vaccines can be less immunogenic and efficacious in developing world settings as compared with industrialized countries. Reasons behind this phenomenon are not well understood, but may relate to continued maternal antigen exposure and high level maternal immunity that is passed to the foetus/newborn transplacentally and/or through breast milk. Therefore, three arising hypotheses include: (i) high-level rotavirus-specific maternal immunity (in the form of anti-rotavirus breast-milk immunoglobulin A (IgA) and transplacental serum IgG) is a major contributor to failed seroconversion following infant vaccination. (ii) Malnutrition negatively impacts infant immunity and increases the risk of post-vaccination rotavirus gastroenteritis. (iii) Introduction of rotavirus vaccine will alter the molecular epidemiology of circulating rotavirus strains detected in vaccinated children presenting with severe diarrhea. To address these hypotheses, the proposed study will recruit a prospective cohort of 420 mother-infant pairs. These will be enrolled at the time of vaccination and followed for up to four years. Baseline immunological status will be ascertained and seroconversion rates determined a month after full immunization. Incident rotavirus gastroenteritis will be monitored in the vaccinated infants whenever episodes of diarrhoea occur; through this surveillance, the sero-strains of rotaviruses causing disease will be tracked over the four year period. Contributions of HIV infection both in mothers and infants, vitamin A and zinc deficiency, weight for age Z-scores as well as mid upper arm circumference will also be assessed. Knowledge gained from this study will inform future interventional trials on strategies to improve rotavirus vaccine effectiveness in the developing world.
Introduction: Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic phenomenon, poorly understood and difficult to predict, complicating intense ovarian stimulation cycle. The most severe symptoms, which associate vascular permeability disorders and hypercoagulability, occur in 0.2 to 1% of the cases and often require intensive care. Activation of endothelial, platelet, erythrocyte or leukocyte cells trigger the release of small specific vesicles, called microparticles, used as markers. Classically leading to endothelial dysfunction and hypercoagulability, the endothelial activation phenomenon could constitute the main cause of OHSS or help predict its severity, as established for various other diseases (cerebral stroke, infarct and lupus…). However, so far, this endothelial activation role has never been studied. Objectives: Evaluate the serum level of microparticles as a predictor of adverse outcomes; correlate it to hypercoagulability and changes of endothelial permeability associated with this syndrome. Methodology: Prospective Pilote Cohort study, evaluating before and throughout the ovarian stimulation cycle (6 samples/patient), the serum modulation of: - Endothelial activation markers (endothelial-derived microparticles, E-selectin) - Procoagulant markers (microparticles from platelet, erythrocyte or leukocyte origin, Von Willbrand factor, thrombin-antithrombin complex, prothrombin fragment 1+2) - Endothelial disjunction marker (soluble CD 146) A group of 50 patients will be assessed Techniques: Flow cytometry for measurement of microparticles expressing non specific (Annexin V) and cell specific surface determinants (CD 31, CD 41, CD 45 or glycophorin A). Use of commercial kits for other serum markers.
This is an observational study aimed to analyze the effectiveness of treatment of patients with newly dg. mantle cell lymphoma not eligible for high-dose therapy and autologous stem cell transplantation. Scheme of treatment: alternating cycles of R-CHOP (rituximab, cyclophosphamide, hydroxydaunomycin, oncovin, prednison) and R-AraC (rituximab, cytarabin): R-CHOP / R-AraC / R-CHOP / R-AraC / R-CHOP / R-AraC. The study was proposed based on the previously published data in the younger patients, which demonstrated improved outcome after implementation of Ara-C into induction.
In this double-blind, randomised and controlled study 150 Patients referred to colonoscopy were assigned to either CO2 or air insufflation. We recorded basic characteristics of colonoscopy and the amount of drugs used for sedation. Patients and investigators filled out questionnaires to record pain, abdominal bloating and flatulence.
Compared to conventional hemodialysis (HD), on-line hemodiafiltration (OL-HDF) achieves a more efficient removal of uremic toxins and reduces inflammation, which could favourably affect nutritional status. The aim of this study was to evaluate the 1-year effect of OL-HDF on nutritional status and body composition in prevalent HD patients.
The investigators will retrospectively analyze and compare data of 2 groups of overweight and obese patients: subjects who followed a diet based on Resting Energy Expenditure (REE) measured by indirect calorimetry and subjects who followed a diet based on REE estimated by the Harris-Benedict equation. Propensity score adjustment will be used to adjust for known differences between the 2 groups
