Filter by:As of March 25, 2020, 414,179 cases and 18,440 deaths secondary to Coronavirus 2019 disease (COVID-19) have been reported worldwide. The unfavorable course of the patients is characterized on the immunological level by an intense pro-inflammatory response which can go as far as a cytokinic storm. This pandemic affects a naive world population from an immunological point of view with respect to SARS-CoV-2 responsible for COVID-19. The evolution is favorable without hospitalization in almost 85% of cases. Among patients hospitalized for pneumonia, some will not require ventilatory support while others will need intensive care. To date, two main types of unfavorable evolution have been described. The first is a bi-phasic evolution beginning with a paucisymptomatic form which is worsened secondarily with respiratory distress associated with a decrease in the viral load in the airways. The second is associated with persistent high viral loads in the airways and detection of the virus in the blood. These different clinical profiles could depend on the quantitative and qualitative response of the innate immune system. At the early stage of a viral infection the innate immunity is capable of detecting certain conserved microbial patterns (PAMP, pathogen-associated molecular pattern) recognized by receptors dedicated to these patterns (PRR, pattern recognition receptor). This process allows to initiate the pro-inflammatory response via different signaling pathways. Activating multiprotein complexes called inflammasomes, which cause pro-IL-1β and pro-IL-18 to be transformed into active pro-inflammatory cytokines are one of these pathways. The central role of inflammasomes in the secretion of these pro-inflammatory cytokines deserves an in-depth study of their activation during COVID-19, whereas the inadequate inflammatory response appears to be the determining factor in the unfavorable development of patients. The objective of this project is to analyze the level of activation of the inflammasomes and then to search for inactivating or activating mutations among the genes which code for the proteins constituting the inflammasomes in Covid-19 patients. The identification of mutations in patients with a serious clinical presentation or even death would be followed by fundamental work by analyzing in a cellular model the impact of these mutations on the secretion of IL-1β.
The current study aims to assess the feasibility, acceptance and clinical outcomes of a practical high-dose aiTBS protocol, including tapering treatments and symptom-based relapse prevention treatments, in patients with unipolar depression previously responsive to ECT and patients needing urgent treatment due to symptom severity during the COVID-19 pandemic.
CovidSurg-Cancer is an international, multicentre, observational cohort study designed to evaluate the 30-day COVID-19 infection rates in elective cancer surgery during the COVID-19 pandemic. Centres can elect to include one or more cancer types in the study, in any combination, depending on local expertise and capacity. During the pilot study, investigators should enrol patients with confirmed diagnoses of: - Colorectal cancer - Oesophagogastric cancer As a rapid response study to the COVID-19 pandemic, included cancer types will evolve throughout the course of the CovidSurg-Cancer study period, for example, to include breast, liver, pancreatic, gynaecological, urological cancers, or sarcomas.
Prone position ventilation is frequently used in the ICU to treat severe hypoxemia in patients with COVID-19 associated acute respiratory distress syndrome (ARDS). The aim of the PROVENT-COVID study is to assess whether applying prone position ventilation immediately after intubation reduces the duration of mechanical ventilation compared to prone position ventilation according to standard criteria for prone position.
In our study; Anxiety and depression levels, socio-demographic characteristics of the pregnant women who were admitted to our hospital between 25.04.2020-25.07.2020 and treated with the diagnosis of covid 19, and the change in anxiety and depression levelsWİTH Beck Depression and Anxiety Score after the disease regressed are planned. (Beck depression scale contains 10 questions and a total of 1 to 100 points is obtained. High score indicates that depression and anxiety are high.) 0-16 points = mild depressive symptoms 17-29 points = moderate depressive symptoms 30-63 points = severe depressive symptoms
Surfactant replacement therapy (SRT) improves oxygenation and survival in NRDS and some infant ARDS. SRT was tried in adult ARDS with conflicting results. Research by Filoche and Grotberg helped to understand the failure of previous clinical trials and yielded a strong scientific rationale for SRT success, now allowing to design a new administration protocol for SRT in adults, to be tested by this clinical trial in COVID-19 adult ARDS patients. Patients will be randomized to receive either a bronchial fibroscopy alone (with aspiration of secretions) or a bronchial fibroscopy with administration of 3 mL/kg of a solution of poractant alpha diluted to 16 mg/mL and distributed into each of the 5 lobar bronchi.
Covid-19 In Tunisia: AN Observational Cross-Sectional Registry Study
COVID-19 infection has spread worldwide causing several deaths in few months Convalescent Plasma from COVID 19 donors has shown huge activity in small series from Chinese patients and currently many centers from USA and the European Union are assessing its use looking to avoid mortality and prolonged hospitalizations COVID-19-related
Convalescent plasma has been shown to be safe and effective for treatment of several diseases. Preliminary data indicates that it is safe and effective for treatment of COVID. However, data is limited to small studies and case series on severely ill patients. In a preliminary safety study 10 patients with severe COVID-19, defined as requiring supplementary oxygen, having fever and a duration of illness less than 11 days were treated with 200 ml of CP. CP was given as a slow infusion without obvious adverse events. Eight patients had viremia. One patient rapidly cleared the virus and recovered following CP treatment. CP infusion did not appear to clear viremia in 7/8 patients. Five of these were eventually admitted to ICU. Thus CP did not appear to cause acute toxicity but did not seem to be effective at the dose used. Viremia seemed to be a marker of a high risk of disease progression The proposed study thus aims to treat a high risk population identified by having viremia irrespective of but hopefully before they develop pulmonary injury such that they require supplementary oxygen therapy. Moreover the dose of plasma will be increased incrementally with the aim of clearing viremia as our initial study indicates that continued viremia is driving COVID-19.
Given the current situation with COVID-19 declared pandemic on March 11, 2020 and the requirement for physical distancing and to limit social interactions, and for some, to quarantine, the investigators will survey patients living with type 1 diabetes (and their families, if they are <18 years) about their current experience with their diabetes management to understand their needs. The primary objective is to describe the exposition and the impact of COVID-19 pandemic on type 1 diabetes. The investigators will recruit people with type 1 diabetes from all ages living in Quebec to answer a short online survey.
