The number of new Coronavirus-2019 (Covid-19) cases is increasing day by day despite the warnings "Stay at home! Wear a mask! Keep social distance!". The aim of this descriptive study is to determine the risk factors that affect the Covid-19 infection in Turkey. The online link of the form created on Google forms was sent to the participants' phones between 18.10.2020 and 18.11.2020.
The primary objective of this study is to determine the vaccine effectiveness of 2 doses of Pfizer-BioNTech BNT162b2 vaccine against COVID-19-associated hospitalization. There will be a large retrospective database study using two parallel study designs: a test-negative case-control design and a retrospective cohort design. VE estimates by various strata and strain type will be conducted.
This is a multicentre observational study with the aim of evaluating the antibody and cellular response after vaccination for SARS-CoV-2 with Pfizer-BioNTech or Moderna vaccines in frail subjects with impaired immuno-competence, due to their underlying diseases or ongoing therapies.
The most recently discovered coronavirus (SARS-CoV-2) may cause illness in humans ranging from the common cold to serious illness, also referred to as Coronavirus disease 2019 (COVID-19). As of January 2021, there are only few authorized vaccines available for the prevention of COVID-19. "CVnCoV" is a new SARS-CoV-2 messenger ribonucleic acid (mRNA) vaccine which is currently being developed for the prevention of COVID-19. The vaccine contains a molecule called mRNA which serves as an instruction manual for the cells in the body to produce a piece of protein from SARS-CoV-2 which activates the body´s defense system. The "CVnCoV" vaccine is injected into the muscle. After the injection, the body recognizes the protein as something that does not belong there. In this way the natural infection with the virus is imitated. The body activates immune cells to produce antibodies against the virus and creates specific immune cells called T cells. "CVnCoV" is given in two doses separated by 28 days. In this study, the researchers will look at how well "CVnCoV" works when the first of the two doses is given together with a flu vaccine called seasonal quadrivalent influenza vaccine (QIV). They will also look at how well the flu vaccine works under these conditions. The QIV is injected into the muscle and is given as 1 dose. To see how well the participants' immune systems is activated by "CVnCoV" and QIV, the researches will measure the levels of specific antibodies against the viruses in the blood. Antibodies are proteins that allow the immune system to find and react to bacteria and viruses in the body. The researches will look into how safe the vaccination is and which type and degree of typical vaccination reactions are seen. To give "CVnCoV" and the flu vaccine together in the future when needed, e.g. during the flu season, would reduce the burden on the health system and on the patients. Participants in this study are adults aged 60 years and older. In this study, participants are assigned to one of the two parallel groups of the same size. The assignment to either group is done by chance via a computer program. Participants in group 1 (Co-ad group) will receive CVnCoV at the same visit as QIV. Participants in group 2 (control group) will receive QIV and CVnCoV at two different visits. The Co-ad group will receive the first dose of CVnCoV and a dose of QIV in opposite arms at Day 1, the second dose of CVnCoV at Day 29, and a placebo injection, i.e. an injection that looks like a vaccination injection but does not contain vaccine, at Day 57. The control group will receive QIV and placebo in opposite arms at Day 1, the first dose of CVnCoV at day 29 and the second dose of CVnCoV at Day 57. There will be five visits and four phone calls. During the study, the study team will take blood samples on four occasions to measure the antibodies against SARS-CoV-2, and nasopharyngeal swabs at 1 occasion. The physicians will do physical examinations at each visit. The participants will be asked how they are feeling and if they have any medical problems. They will, in addition, receive an electronic Diary to report medical problems.
The purpose of this observational nationwide study is to evaluate the effects of three different COVID-19 vaccines for the outcome of different severities of incident COVID infection.
The purpose of this study is to Understand the natural history of Coronavirus 2019 (COVID-19) infection to better define the period of infectiousness and transmissibility and to establish biobanks of COVID-19 blood and mucosal samples.
Infectious diseases pose a threat to the life of individuals worldwide. The pandemic has highlighted the need to develop an innovative and cost- effective large population-based screening methodology. The investigators propose a two-fold improvement barcode-labeled testing strategy specifically for pooled samples. This platform combines isothermal amplification and real-time electrochemical detection; electroactive modified loop probes will be used in the amplification step for barcode readout. This method enables four samples pooled detection at the same time. This platform will be integrated into a disposable microfluidic chip that allows minimal human intervention during the process to realize a massively parallel screening platform for infectious disease pathogens. Objectives 1. To develop a sensing method for concurrent electrochemical-tag coded isothermal amplification and real-time electrochemical detection; 2. To design a molecular strategy to barcode four individual samples so that they can be pooled together and to simultaneously amplify and identify a positive individual, if any, from the pooled sample. 3. To fabricate a microfluidic device integrating the sample processor and barcoding module with the nucleic acid amplification and detection step for large-scale population screening of up to 100 individuals. 4. To validate the performance of the prototype using clinical specimens and benchmark it against the detection data from commercially available testing equipment.
TRIAL LAC is a randomized double-blind non profit multicenter study with a nutritional product: bovine lactoferrin - Mosiac 200 mg. the hypothesis to be confirmed is that bovine LF, administered daily orally in addition to standard therapies for 1 month to hospitalized patients with Covid-19 infection, can be useful to limit the severity, progression of the disease, shorten the time of swabs negativization (i.e. time required to eliminate the virus) and to reduce the morbidity load associated with it. Patient recruitment will involve 2 centers in Italy: Ospedale degli Infermi (Ponderano, Biella) and AOU Maggiore della Carità (Novara). The subjects enrolled will be randomized to two Groups: Group A (experimental arm) - Standard Anti-Covid-19 Therapy + Oral Administration of Bovine Lactoferrin (fixed dose 800 mg / day) for 30 days Group B (control arm) - Standard anti-Covid-19 therapy + Placebo administration (identical capsule with the same amount as an inert compound, starch of corn powder), according to the same pattern of use. It should be specified that the study treatment and placebo will be administered in addition to the standard care in place, and therefore in addition to all the pharmacological treatments currently used in clinical hospital practice against Covid-19.
Aim:There is still not enough data to determine methylprednisolone treatment timing, dosage, duration of use and indication in Covid 19 pneumonia. The aim of this study is to examine the relationship between drug dose and hospitalisation time and mortality rates in patients with pre-diagnosis of severe covid pneumonia and systemic methylprednisolone. Materials and Methods: The demographic data, symptom durations, thorax CT findings, methylprednisolone dose and duration of treatment, hospitalisation times, intensive care hospitalizations of the patients who were initiated and hospitalized in the emergency department will be retrospectively recorded. Finally, the fate of the patients (such as discharge, referral, death) will be recorded.Statistical analysis will be conducted using the Statistical Package for Social Sciences (SPSS) (IBM Corp. Released 2015. IBM SPSS Statistics for Windows, Version 21.0. Armonk, NY: IBM Corp.) program.
