Active clinical trials for "COVID-19"

The medical and paramedical staff of the front-line services are potentially exposed to SARS-CoV-2. Therefore, despite the application of standard protective measures, it is possible that a certain number of these personnel have already contracted SARS-CoV-2, including in its asymptomatic form. Serological testing in this context would be useful for deploying immune healthcare workers as to limit the risk of viral infection and transmission. Therefore, it is of utmost importance to prove that the serological response entails the production of neutralizing antibodies.

Background: Nasopharyngeal (NP) swabbing is being used to test for SARS-CoV-2 infection. For this, a swab is inserted deep into the back of the nose to collect a sample. It can cause discomfort for most people. Researchers want to find an easier way to collect samples. Objective: To learn if testing for SARSCoV-2 with a saliva sample only, a nasal swab from just the front part of the nostril only, or a saliva sample plus a nasal swab gives results that are as accurate as the NP swab. Eligibility: NIH staff members age 18 and older who are taking part in NIH CC SARS-CoV-2 surveillance. Design: The Occupational Medical Service (OMS) collects NP swabs as part of standard NIH staff screening. Participants will give 1 or 2 saliva samples and 1 or 2 nasal swabs when their NP swab is collected by OMS. If their NP swab was already collected, their OMS record will be reviewed for the result. If the NP swab result is positive, the participant will have another NP swab. At that time, they will also give 1 or 2 saliva samples and 1 or 2 nasal swabs. If the NP swab result is negative, they will give 1 or 2 saliva samples and 1 or 2 nasal swabs the next time they have an NP swab. For the saliva sample, participants will spit into a tube. For the nasal swab, the inside of the front part of the nostril will be swabbed. Participation ends after the study samples are collected. Participants can choose to keep giving saliva and nasal swab samples each time they have an NP swab.

There is little information about the clinical characteristics and risk factors of Covid-19 in Latin American countries considering the ethnic differences and the high prevalence of obesity and cardiometabolic diseases. The aim of the study was to evaluate the association between laboratory tests and the risk of complications in SARS-CoV-2 infection and to determine their mortality risk factors in a sample of the Mexican population. A retrospective cross-sectional study of the routinely collected data was performed in the Hospital Regional de Alta Especialidad de Ixtapaluca (HRAEI), State of Mexico. Adult patients (aged ≥18 years) with positive RT-PCR for SARS-CoV-2 and oxygen support that were admitted between March 28 and May 5, 2020, were included

This research will provide data on thermal condition of medical workers who use personal protective equipment from biological hazards. Aquired data will be used to define acceptable period of use for these protective costumes. This research will recruit 6 volunteers. During 6 hours each subject will perform their work using protective costume. Heart rate, skin and air temperature under costume and hygrometric data will be registered. Also there will be questionnaires for volunteers for subjective assessment of thermal and moisture sensations.

Evaluation of the rate of positive RT-PCR SARS-CoV-2 test at 1 month of COVID infection among elderly people. It is unclear how long an individual with COVID-19 will remain "sick" and "contagious". It appears that SARS-CoV-2 can be transmitted before symptoms appear and throughout the course of the disease. They investigators did not find any study on a COVID + geriatric population reassessing carriage at 1 month even though age seems to be a risk factor for prolonged excretion as suggested in the study following study: Xu K, Chen Y, Yuan J, Yi P, Ding C, Wu W, et al.

Between March and May 2020, Ile-de-France hospitals faced an influx of patients infected with the COVID 19 virus. Faced with the scale of the pandemic, the aggressiveness of this pathology, severe respiratory complications and the shortage of resuscitation beds , the teams had to make difficult decisions on the therapeutic strategy, the orientation of patients in the event of respiratory distress and their intensive care status. To do this, each establishment reflected in an emergency context on procedures for collegial deliberation and assistance in ethical reflection, based on the recommendations of the National Consultative Ethics Committee and learned societies such as the French Society. of Anesthesia and Resuscitation or the French Society of Support and Palliative Care. Some hospitals had already institutionalized the ethical approach upstream of the health crisis. For example, the Groupe d'Aide à la Réflexion Éthique Clinique (GAREC) was created in November 2005 within the Paris Saint-Joseph Hospital Group. GAREC is a collegial and multidisciplinary entity, made up of 8 members who intervene at the request of caregivers when a clinical situation turns out to be ethically complex. He gives an advisory opinion, the decision belonging to the referring physician. At the start of the COVID period, GAREC changed its structure, organization and operation in order to respond to the multiple issues posed by the complexity of the health situation. This study seeks to analyze the adaptation mechanisms put in place by this group during the epidemic period as well as the nature of the benefit provided to the caregivers who requested it, to the patients and to their relatives. Adaptation mechanisms: during the COVID period, GAREC was extended to other paramedical professions (psychologists, nurses), thus increasing from 8 to 15 members. It has set up 2 weekly meetings, an on-call duty and on-call duty. The requests were made easier: they could be done by phone, by email, day or night. Several questions emerge: What were the motivations for enlarging the group? How were the members integrated into this group? What were its operating methods? How and by whom was it seized? For what purpose? Were the intervention teams multidisciplinary? Nature of the benefit provided by GAREC: it will be approached by semi-structured interviews via a qualitative research method. This work is part of a broader reflective perspective: What representation of ethics underlies this device? Does the institutionalization of ethics help to enhance or make invisible what ethics owes to daily healthcare practices? To what extent does the institutionalization of clinical ethics make health institutions more human and virtuous? Under what conditions can a device like GAREC go beyond the role of ethical guarantor and transform the institution and nursing practices in the service of a collective reflective approach? This study will be carried out on patient data usually collected as part of their care and on data collected through semi-structured interviews with healthcare professionals. As such, it fits into the perspective of grounded theory.

Aim: We aim to evaluate αvβ3 integrin expression in proven COVID-19 infected patients with indicative findings on routine contrast-enhanced CT using [68Ga]Ga-DOTA-(RGD)2. If activated vascular endothelium in the lung parenchyma proceeds ARDS, as frequently observed during COVID-19 infection, imaging αvβ3 integrin expression using PET/CT could have potential as a clinical tool to characterize patients at early stages during disease and guide development of novel treatments targeting the vascular endothelium. Study design: This is a prospective, observational non-randomized pilot study. Maximum 10 patients will undergo a [68Ga]Ga-DOTA-(RGD)2 PET/CT scan and CT-subtraction scan in the same procedure. 10-minutes/bed position static [68Ga]Ga-DOTA-(RGD)2 PET/CT scans of the thorax will be acquired starting at 60 minutes post injection. Study population: Maximum 10 patients from the Infectious Diseases ward with proven COVID-19 infection and indicative pulmonary abnormalities on contrast-enhanced CT (CORADS 4-5) undergo PET/CT scans after injection of 70 μg (200 MBq) [68Ga]Ga-DOTA-(RGD)2 and CT-subtraction. Intervention: All patients will undergo a [68Ga]Ga-DOTA-(RGD)2 PET/CT scan, and in the same procedure, a CT-subtraction scan. Primary study objective: The primary objective of this study is to demonstrate and quantitate activation of the endothelium in the lung vasculature using [68Ga]Ga-DOTA-(RGD)2 PET/CT. Secondary study objectives: To assess the spatial correlation between [68Ga]Ga-DOTA-(RGD)2 uptake and abnormal findings on routine contrast-enhanced CT scan of the chest To assess the spatial correlation between [68Ga]Ga-DOTA-(RGD)2 and CTS of the lung parenchyma To assess the correlation between [68Ga]Ga-DOTA-(RGD)2 and laboratory results To explore the correlation between [68Ga]Ga-DOTA-(RGD)2 uptake and clinical course of disease

Background. The current coronavirus disease (COVID-19) has a great impact worldwide. Healthcare workers play an essential role and are one of the most exposed groups.Information about the psychosocial impact on healthcare workers is limited. Methods. 3109 healthcare workers completed a national, internet-based, cross-sectional 45-item survey between 9 and 19 April 2020. The objective is to assess the psychological impact of the COVID-19 pandemic in Spanish healthcare workers. A Psychological Stress and Adaptation at work Score (PSAS) was defined combining four modified versions of validated psychological assessment tests (A) Healthcare Stressful Test, (B) Coping Strategies Inventory,(C) Font-Roja Questionnaire and (D) Trait Meta-Mood Scale.

NLR has previously been observed to correlate with complications in upper GI (1) and colorectal (2) surgery. The investigators sought to assess if a similar correlation can be identified in emergency general surgical patients and if the presence of suspected or confirmed COVID-19 may impact on this. Given the heterogeneity of emergency general surgery the investigators therefore plan to perform a retrospective review of patients having emergency laparotomies only at a single NHS site during COVID-19 pandemic. Assessment of outcomes and Neutrophil:lymphocyte ratio as a predictor of outcomes will be completed. Outcomes will be completed in line with the recent COVIDSurg study criteria (3). The primary outcome is 30-day mortality. Secondary outcomes are 7-day mortality, re-operation, length of stay, post-operative respiratory failure, post-operative ARDS (Acute Respiratory Distress Syndrome), post-operative sepsis and ITU (Intensive Therapy Unit)/HDU (High Dependency Unit) admission.
