Filter by:The clinical picture of the novel corona virus 2 (SARS-CoV-2) disease (COVID-19) is rapidly evolving. Although infections may be mild, up to 25% of all patients admitted to hospital require admission to the intensive care unit, and as many as 40% will progress to develop severe problems breathing due to the acute respiratory distress syndrome (ARDS). ARDS often requires mechanical ventilation, with a 50% risk of mortality. Researchers at the Ottawa Hospital Research Institute (OHRI) have been studying the potential therapeutic role of mesenchymal stromal/stem cells, or MSCs, for the treatment of ARDS for over a decade. This has led to the world's first clinical trial using MSC therapy for patients with severe infections (sepsis) which is often associated with ARDS (NCT02421484). This trial demonstrated tolerability, and potential signs of efficacy. In addition, the investigators have established expertise in producing clinical-grade MSCs and have received approval from Health Canada for the use of MSCs in three different clinical studies. This protocol consists of 2 sequential trials using the same trial infrastructure, noted as the Phase 1 trial 'CIRCA-1901' and the Phase 2a trial 'CIRCA-1902'. CIRCA-1901 is an open-label, dose-escalating and safety trial using a 3+3+3 design to determine the safety, and maximum feasible tolerated dose of repeated delivery of Umbilical Cord Mesenchymal Stromal Cells (UC-MSC) intravenously. The investigators will enroll up to 9 patients; each receiving repeated unit doses of UC-MSCs delivered by IV infusion on each of 3 consecutive days (24±4 hours apart) according to the following dose-escalation schedule (3 patients per dose panel): (i) Panel 1: 25 million cells/unit dose (cumulative dose: 75 million MSCs), (ii) Panel 2: 50 million cells/unit dose (cumulative dose: 150 million MSCs), (iii) Panel 3: up to 90 million cells/unit dose (cumulative dose: up to 270 million MSCs). If no safety issues are identified, we will continue to the Phase 2a trial. CIRCA-1902 is a single-arm, open-label extension of the CIRCA-1901 trial to assess early signs of efficacy (major morbidity and mortality). The Phase 2a trial (CIRCA-1902) will enroll 12 patients to assess early signals of benefit on mortality and major morbidity in a high risk, high mortality population.
A retrospective study on clinical and radiological findings in ME/CFS
This prospective cohort study aims to compare the proportion of cardiac or cerebrovascular events after a first stroke, a first transient ischemic attack (TIA) or recurrent TIA, between sleep-disordered breathing (SDB) and non-SDB (control) patients, one year after SDB diagnosis, performed 3 months after stroke onset. The primary outcome is a composite endpoint composed of cardiac or cerebrovascular events regrouping: death from any cardiac or cerebrovascular cause, non-fatal stroke, and non-fatal acute coronary disease. 1620 patients, in the acute phase of a first stroke, TIA or recurrent TIA will be included in the cohort. Clinical, neuroimaging, sensorimotor, cognitive and biological parameters will be collected at inclusion. Three months after stroke or TIA onset, polysomnography will be performed for SDB diagnosis. Patients will be considered as having SDB for an Apnea-Hypopnea Index (AHI) > 15 events/hour, or to the control group otherwise. The same clinical, imaging, cognitive and biological assessments than during the first visit will be performed; incident (new) cardiovascular events will be collected. Three months later, and at 1, 2, 3, 4 and 5 years after SDB diagnosis, the same clinical, cognitive, sensorimotor, and sleep-related evaluations will be performed. In addition to the aforementioned parameters, incident cardiovascular outcomes will be collected, at the same time points. The primary study outcome will be retrieved one year after stroke onset.
Myelodysplastic syndromes (MDS) comprise a heterogeneous group of clonal bone marrow neoplasms that predominate in the elderly, with a median age at diagnosis of 70 years. The diagnosis of MDS relies on peripheral blood cytopenia and morphologic dysplasia for one or more hematopoietic cell lineage. Cytopenia is evidenced with hemogram while dysplasia requires bone marrow aspirate, which is an invasive procedure . Considering the low prevalence of disease among subjects referred for suspected MDS, many patients are exposed to unnecessary bone marrow aspiration-related discomfort and harms. Therefore, an objective assay based on a peripheral blood sample that accurately discriminates MDS from other cytopenia etiologies is highly desirable. We have previously developed and refined a flow cytometric analysis protocol for quantifying neutrophil MPO expression in peripheral blood at three university-affiliated hospitals (i.e., Clermont-Ferrand, Saint-Etienne, and Grenoble) (Raskovalova et al, Hematologica 2019). We found that the robust coefficient of variation (RCV, computed as the robust standard deviation divided by the median) within an individual subject was the best parameter in discriminating patients with versus without MDS. Although promising, flow cytometric analysis of neutrophil MPO expression in peripheral blood is technically complex, time consuming, and not standardized. Hence, its performance requires specific expertise and the results show substantial variability. A single ready-to-use tube with lyophilized antibodies would have the potential to standardize the measurement of neutrophil MPO expression in peripheral blood across laboratories, with results available within 30-60 min in routine practice. In this study, the investigators hypothesize that a standardized and semi-automatic flow cytometric assay of neutrophil MPO expression in peripheral blood could accurately rule out MDS and obviate the need for bone marrow aspiration and biopsy, with sensitivity and negative predictive value estimates approaching 100%. In this observational diagnostic accuracy study, burden will be null for recruited patients. No specific intervention is assigned to participants. All diagnostic testing, procedures, and medication ordering are performed at the discretion of attending physicians. A test result will have no impact on patient management. .Compliance with current guidelines disseminated by the French Haute Autorité de Santé (HAS) will be advocated for the diagnostic work-up of patients with suspected MDS. No follow-up visits are planned in this cross-sectional study.
In this study the investigators will follow the neurodevelopmental outcome of children with in utero ZIKV exposure who do not have microcephaly or severe abnormalities consistent with Congenital Zika Syndrome. The ZIKV-exposed children will be compared to non-ZIKV exposed controls. Children will be assessed at age 3 and 4 years using standardized neurodevelopmental assessments. Children will also have neurodevelopmental assessment at age 5 and 7 years along with a brain MRI at age 7 years.

the university students will respond to CVS-F3 survey form and then they will be subjected to complete ophthalmic examination and investigations
Polycystic Ovarian Syndrome (PCOS) is the most common endocrinological disorder in women of reproductive age, and its prevalence is reported to be 6-21% in women aged 15-49 (1). Although its etiopathogenesis is still not clear, it is known that it is due to the disregulation of ovarian steroidogenesis under the influence of some environmental and genetic factors. Diagnosis of ESHRE / ASRM has set Rotterdam criteria in 2003; one of these criteria is the presence of hyperandrogenism (2). Hyperandrogenism leads to an increase in general muscle mass in the body (1, 3, 4). Pelvic floor muscles are associated with urethra in the anterior compartment, rectum and anus in the posterior compartment, and uterine support in the apex; major urinary and fecal continence ensuring its functions in order to stop in the appropriate position of the pelvic organs (5). The well-being of the pelvic floor muscle strength has a protective effect from urinary and fecal incontinence. It has been emphasized that the "anogenital distance" determined by the measurement of the anal region anterior to the clitoris anterior may also be a criteria in the diagnosis of Polycystic Ovary Syndrome (7,8,9). In this study, patients in the reproductive age between 18-40 years, who applied to our gynecology outpatient clinic and were diagnosed as PCOS according to Rotterdam criteria wil be study gorup and the women without PCOS will be control group. We aimed to evaluate the pelvic muscle strength with perineometry, to measure anogenital distance and to determine possible relationships with each other. In addition to demographic information, ICIQ-SF (Urinary incontinence inquiry short form) will also be taken to evaluate pelvic floor function (10).
This trial investigates the use of Daratumumab (DARA), an antibody directed at the human cluster of differentiation 38 (CD38) molecule, for the treatment of patients with Polyneuropathy, Organomegaly, Endocrinopathy, m Protein Component, Skin Changes (POEMS) syndrome. This trial will enroll ten subjects, who will complete 12 four-week cycles of DARA, in combination with the immunomodulatory drug (IMiD) lenalidomide. Objectives of this study include improvement in neuropathy and performance status, as well as improvement in laboratory values and survival.
