Filter by:"Background France counted on January 1, 2020, 70,651 people detained, for 61,080 places. Overcrowding in detention is considered as risk factor for infectious diseases transmission, such as respiratory infections. The prison environment represents a confined environment, which could protect prisoners from possible external contamination. If one or more inmates were infected through visiting rooms, officers working in detention, or newly incarcerated people, an epidemic could spread more quickly in the prison community. Thus, few cases of COVID-19 were observed among the subjects in detention with a few weeks delay compared to the free world. However, detention conditions make it more difficult to detect suspicious cases. On the other hand, carrying out diagnostic tests is structurally more difficult to carry out there. Thus, given the plurality of clinical presentations, the non-optimal sensitivity of the SARS-CoV-2 RT-PCR, and the difficulty in carrying out diagnostic tests, it is today difficult to have a precise idea of the number of prisoners having encountered SARS-CoV-2. It is also a population that is not taken into account in the large seroprevalence studies currently conducted in the general population. In order to estimate the number of prisoners exposed to SARS-CoV-2 and in the absence of data currently available in the medical literature, a seroprevalence study in this at risk and little studied population would bring new data to the medical community. Hypothesis In adult subjects living in penal establishments in Ile de France, the seroprevalence of SARS-CoV-2 would be lower compared to the general population. Material and method Open multicenter cross-sectional study carried out in the 11 penal establishments of Ile de France. A sampling of 3,500 inmates stratified over the 16 detention areas concerned will be carried out. The inclusion criteria will be detained subjects who have expressed their consent to participate in the research, aged 18 to 80 years. Each selected detainee will be invited to the health unit to perform a venous blood test for anti-SARS-CoV-2 antibodies. The goal is to take 2,500 blood samples (30% expected refusal rate). Each sample will be analyzed in the virology laboratory at P. Brousse hospital. Expected results Obtain an assessment of the seroprevalence of SARS-CoV-2 in prisons to determine the exposure of detained persons. This assessment will make it possible to undertake public health actions and to propose the implementation of group protection measures such as vaccination if this is soon available.
This study aims to evaluate the safety and reactogenicity profile after 1 and 2 dose administrations of investigational SARS-CoV-2 mRNA vaccine (CVnCoV) at different dose levels and to evaluate the humoral immune response after 1 and 2 dose administrations of CVnCoV.
Complete blood count parameters are routinely evaluated cost-effective markers in diagnosis and clinical follow-up of infectious diseases.There is increasing number of studies to report the course of COVID-19 in pregnancy. The current study aimed to elucidate the changes in hematologic parameters in response to SARS-CoV-2 infection and whether there was an increase in adverse perinatal outcomes such as increased neonatal intensive care unit admission and lower APGAR scores in pregnancies with COVID-19.
The aeronautical community was also affected and greatly impacted economically and socially by the Covid-19 pandemic. Away from the acute phase, the epidemiological impact and the consequences of this disease within the French aviation flight crew population must be assessed. This study is aimed at providing original epidemiological data among civil and military aircrew, prior to possible prevention strategies or countermeasures to optimize risk management in terms of aviation safety and to promote, if necessary, future targeted studies.
COVID-19 is a disease caused by the virus, SARS-CoV-2. Patients with this viral infection are at risk for developing pneumonia and acute respiratory distress syndrome (ARDS). Approximately 20% to 30% of hospitalized patients with COVID-19 and pneumonia require intensive care for respiratory support. Clinically, ARDS presents with severe hypoxemia evolving over several days to a week in combination with bilateral pulmonary infiltrates on chest X-ray. Widespread alveolar epithelial cell and pulmonary capillary endothelial injury can lead to severe impairment in gas exchange. In one report of 1,099 patients hospitalized with COVID-19, ARDS occurred in 15.6% of patients with severe pneumonia. In a smaller case series of 138 hospitalized patients, ARDS occurred in 19.6% of patients and in 61.1% of patients admitted to an intensive care unit (ICU). To date, no effective treatment has been established to treat COVID-19 or to prevent progression of ARDS. It is thought that a heightened immune response with an unbalanced release of inflammatory mediators in the airway is a major cause of morbidity and mortality associated with the disease. It is therefore reasonable to postulate that improved outcomes may be obtained in patients with a balanced immune response with adequate viral control and appropriate counter-regulatory immune responses whereas a poor outcome may be expected in patients with inadequate viral control or a heightened immune response or what is referred to as a "cytokine storm". Thus, modulating the pulmonary immune response without suppressing the immune system would be a viable strategy for patients with COVID-19. The current literature supports the role of neuromodulation, particularly vagal nerve stimulation (VNS), in modulating the immune response. Modulating the pro-inflammatory pathway through VNS has been demonstrated to decrease inflammatory mediators and improve outcomes in several animal models and in humans. Percutaneous electrical nerve field stimulation (PENFS) provides a novel, non-invasive method of VNS through a non-implantable device applied to the external ear. Already, the FDA has cleared this technology for reducing symptoms of opioid withdrawal in patients with opioid use disorder. Symptoms of opioid withdrawal can be decreased by approximately 90% after 1 hour of stimulation. Similarly, the IB-Stim device has been shown to improve symptom in children with abdominal-pain-related functional GI disorders and recently received market approval by the FDA for that indication. Unpublished studies have demonstrated marked decrease in inflammation with PENFS compared to sham stimulation in a model of TNBS colitis. While the efficacy of PENFS in modulating the progression of pulmonary disease in patients with COVID-19 is unknown, several proposed mechanisms for regulation of the immune response through VNS have already been demonstrated. We propose to perform an open label, randomized study to evaluate the efficacy of PENFS for the treatment of respiratory symptoms in patients with COVID-19.
This is a randomized, placebo-controlled, double-blind phase I clinical study of anti-SARS-CoV-2 equine immunoglobulin F(ab')2 fragments (INOSARS) to evaluate the safety and antiviral efficacy for the treatment of adult patients with mild COVID-19 and low risk of disease progression.
The main purpose of this research study is to learn the rate of SARS COV-2 on HIV infected children, adolescents, and youth receiving their primary HIV care at the University of Miami Miller School of Medicine.
To determine if there is a need for further education on vaccines with psoriasis patients who are on a biologic. In regards to the COVID-19, it is important that psoriasis patients - whether on a biologic or not - understand whether they can have certain vaccines. That will depend on the type of vaccine that becomes available.
This questionnaire is distributed via a mailing list (e-mail) of patients treated within the framework of the FHU for pathologies including chronic inflammatory bowel diseases or IBD (Crohn's disease and ulcerative colitis), inflammatory rheumatic diseases (such as rheumatoid arthritis and ankylosing spondylitis), but also asthma, psoriasis, atopic dermatitis as well as systemic autoimmune (such as scleroderma, lupus, angioedema) and neurological (multiple sclerosis) diseases. A two-step analysis will be conducted: impact of lock down(March 17, 2020 - May 11, 2020) and a 2-month assessment of end of lock down (from May 11, 2020) on issues addressing: overall impact, impact on the disease, treatment and follow-up, and access to information related to the epidemic during these periods.
Ultrasound can reliably detect morphologic changes associated with pneumonia. Additionally, protocols were elaborated which unify the investigation procedure and improve the intra- and interrater reliability. Moreover, ultrasound is a time and cost-effective and widely available method. The aim of this study is to evaluate the efficacy of the ultrasound of the lungs in predicting the length of hospitalization, of intensive care and of mechanical ventilation in Covid-19 pneumonia. Further aims are the evaluation of the efficacy of the ultrasound of the lungs in predicting the risk of death and of long-term pulmonary complications as consequences of Covid-19 pneumonia.
