Swift and decisive actions on the part of healthcare and hospital authorities are required to effectively contain the current COVID-19 pandemic. These measures firstly allow personnel and facilities leeway to provide surge capabilities to meet anticipated increased demands on the healthcare service. In addition, by deferring none urgent hospital visits, admissions and investigations, such measures support social distancing and aid attempts to control disease transmission. Deferring perceived non-urgent patient services may however lead to unintended delayed diagnoses and exacerbation of current patient conditions and lead to increased emergency admissions and surgeries. A policy decision was made that essential surgical services pertaining to cancer and urgent cardiovascular surgery were allowed but that surgeons had the option to postpone what is assessed to be less urgent cases. Increasingly patients also postpone their surgeries or visits because of anxieties over the developing situation. Elective surgical services at the Outram Campus were thus significantly reduced from January 2020 as part of the measures to contain the COVID-19 outbreak. The surgical philosophy during this period was that a judicious policy that allowed surgeons to proceed with surgery deemed critical but to postpone those deemed less so will at the system level, avoid poor outcomes for patients who required surgery and yet successfully re-allocate resources required to address the unfolding pandemic.
This is an open-label phase 1/2, dose-escalation study. Participants will receive a single intramuscular (IM) dose of IMNN-101 on Day 0 in the deltoid muscle and will be followed through 12 months post-vaccination (through Study Day 365).
This is an open label, phase III trial - immunobridging study. There will be only 1 group in the study. All subjects (12 to 17 years old) will receive INAVAC 5 µg dose. The vaccine will be administered with 2-dose schedule, intramuscularly, with 28 day interval. All subjects will be followed for 12 months. INAVAC is an inactivated vaccine made of SARS-CoV-2 virus isolated from a patient in Surabaya, composed with aluminium hydroxy gel, tween 80, and L-histidine, and this study will be the first phase III in adolescents.
Background. Guidelines on COVID-19 management are developed as we learn from this pandemic. However, most research has been done on hospitalised patients and the impact of the disease on non-hospitalised and their role in transmission are not yet well understood. The COVID HOME study conducts research among COVID-19 patients and their family members who were not hospitalised during acute disease, to guide patient care and inform public health guidelines for infection prevention and control in the community and household. Methods. An ongoing prospective longitudinal observational study of COVID-19 outpatients was established in March 2020 at the beginning of the COVID-19 pandemic in the Netherlands. Laboratory confirmed SARS-CoV-2 infected individuals of all ages that did not merit hospitalisation, and their household (HH) members, were enrolled after written informed consent. Enrolled participants were visited at home within 48 hours after initial diagnosis, and then weekly on days 7, 14 and 21 to obtain clinical data, a blood sample for biochemical parameters/cytokines and serological determination; and a nasopharyngeal/throat swab plus urine, stool and sperm or vaginal secretion (if consenting) to test for SARS-CoV-2 by RT-PCR (viral shedding) and for viral culturing. Weekly nasopharyngeal/throat swabs and stool samples, plus a blood sample on days 0 and 21 were also taken from HH members to determine whether and when they became infected. All participants were invited to continue follow-up at 3-, 6-, 12- and 18-months post-infection to assess long-term sequelae and immunological status.
Objectives: To describe the standardized evaluation of the psychological and cognitive function of long COVID patients and their evolution, to compare immunological and HPA-axis related biomarkers between long COVID patients and healthy controls, to explore cross-sectional and longitudinal associations between immunological measures and long COVID symptoms. Study design: Cov-N-Psy is a longitudinal observational study. Three groups will be included from 2021 until 2023: long COVID patients with neuropsychological complaints (P), COVID-survivors without persistent complaints (Ca) and healthy volunteers without a history of COVID-19 (Cb). The total sample size is estimated on 130. Four visits are organized: at baseline, three, six and twelve months. The study is organized in three work packages (WP). WP1 includes a blood withdrawal and psychometric questionnaires and is part of every visit. WP2 includes cortisol measurement in saliva and takes place on the baseline visit for every participant and on the third visit for patients. Finally, WP3 includes a neurocognitive assessment at baseline for patients and Ca controls and on the third visit for patients.
Descriptive, retrospective, observational, anonymous, study to evaluate the potential effect of incorporating calcifediol into the therapeutic protocol of patients hospitalized for COVID-19 on mortality and other outcome variables, such as admission to the Intensive Care Unit (ICU), to "Gerencia de Atención Integrada (GAI) de Albacete". "Complejo Hospitalario Universitario de Albacete". Albacete (Spain)", based on the files of the MXXI medical records, Information System of the Laboratory (ISL) and Pharmacy.
This is a multicenter, observer-blind, randomized, controlled phase 3 study to evaluate the immunogenicity, reactogenicity, and safety of an investigational self-amplifying RNA COVID-19 vaccine (ARCT-2303) administered concomitantly with quadrivalent influenza vaccines or standalone in adults who previously received authorized COVID-19 vaccine.
There is no cure for cold or flu, most people recover in about within two weeks. Paracetamol may be used to reduce aches or treat fever, headache, or body aches. Antiviral solutions ranging from simple universal saline solutions to novel compounds have been proposed to provide a temporary barrier to prevent viral infection and propagation. The nasal spray "Humer Stop Virus" is indicated in patients presented with early symptoms of viral respiratory infection. This spray forms a protective barrier in the nasal mucosa which is the main entry of the upper air respiratory system viruses. The spray traps the viruses and helps the organism to eliminate them before they multiply themselves. This clinical investigation is conducted to assess the performance, clinical benefit and safety of this nasal spray in patients with early symptoms of acute respiratory disease whether or not infection is related to common cold, flu or COVID virus. Indeed, presence of early symptoms of acute respiratory infection does not always imply viral infectionAntigen self-tests are available to confirm viral infection with flu viruses or severe acute respiratory syndrome (SARS-CoV-2). However, influenza and other winter viruses are not systematically searched for in general population, because this is of neither collective nor individual interest. To be as pragmatic as possible, we chose to assess performance and safety of the nasal spray on intended users in real conditions. Patients with early symptoms of cold, flu or COVID, are enrolled regardless their PCR test positivity confirming viral infection at the time of enrollment. For study needs, the primary endpoint, which aims to assess the performance of the nasal spray in terms of stopping the viral infection, is assessed in a subgroup of patients with a positive PCR test with flu, COVID or common cold virus in the nasal sample collected at enrollment.
The goal of this clinical trial is to evaluate the safety, tolerability, and pharmacokinetics of GS-441524 in healthy subjects. The main questions to answer are: 1) What dosage of GS-441524 is required for adequate therapeutic plasma levels? 2) Does fed or fasted state produce variability in plasma levels? 3) How is GS-441524 eliminated from the body. Participants will receive varying levels of GS-441524 or placebo to evaluate AEs and plasma levels.
