Active clinical trials for "COVID-19"

Cancer patients are among the most vulnerable individuals, whose health-related quality of life (HRQOL) may be substantially impacted by the COVID19 pandemic. We want to study how the COVID-19 pandemic influences the life of cancer patients and how these patients cope with the additional distress with the aim to facilitate the development of improved future interventional strategies to maintain resilience and HRQOL

The main objective of this part of the project is to identify the germline genetic factors which discriminate the benign and severe forms of SARS-CoV2 (CoVID-19) infection in the context of the ongoing SARS-CoV2 (HCOVID-19) epidemic. The scientific arguments of the project are described in APPENDIX. We hypothesize that pathogenic variants in genes coding for crucial factors involved in the HOST PATHOGEN interaction could explain the susceptibility of some patients to severe disease, even in the absence of comorbidities. The challenge is to identify those of the genetic factors who may be related respiratory distress and potentially further death. Based on our previous experience in sarcoidosis, a multifactorial disease predisposing to opportunistic infections, we will focus particularly the regulation of apoptosis and autophagy, immune response to viral infection, and endoplasmic reticulum stress response (ER STRESS) which is closely linked to apoptosis. Genetic defects in such pathways may decrease the clearance of viral particles and induces the progressive invasion by SARS-CoV2 and destruction of lung parenchyma. Our strategy will be similar to that described in our previous studies on sarcoidosis, recently published. We will combine a comparative genotype analysis by WHOLE EXOME SEQUENCING (WES) of benign and severe forms of SARS-CoV2 infection through clinical subgroups defined by the infectious diseases experts and a bioinformatics analysis of the functional networks identified by the panel of genes sharing pathogenic variants and discriminating the severe forms of the diseases. WES data will be carefully analyzed and related to all the intracellular physiological process and also the functional pathways involved in host-pathogen interaction: viral targets on the cell surface and downstream signaling, viral genomic RNA replication and translation, production and release of new viral particles. Finally, our main objectives are the definition of a gene panel more specifically related to severe forms of infection and the characterization of defective pathways involved in pejorative forms of SARS-COv2 disease in order to identify putative therapeutic targets.

The aim of the regional online questionnaire is to better understand the pattern of acute infection and the time of recovery of various symptoms.

The aim for this study is further to elucidate the presence of dysautonomia in post-covid-19 patients, by evaluating heart rate variability.

The recent Coronavirus Disease 2019 (COVID-19), has caused a global pandemic, and development of safe, effective vaccines is mandatory to return back to pre pandemic life. Many vaccines have been developed and requested by the authorities after the emergency license issued. The main mechanism of protection is through humoral and cell-mediated immune responses that might reduce the potential for disease development or severity. Cytotoxic T cells clear virus-infected host cells and contribute to control of infection. Preliminary data are now available indicating safty and effecacy of different vaccines . The vaccines were tolerated, with induction of neutralizing antibodies and antigen-specific T cells against the SARS-CoV-2 spike protein. The aim of this work is to evaluate the immune responses in adults, aged 25-65 years, up to 8 weeks after vaccination with a single and double doses live inactivated (Sinopharm), mRNA (Pfizer/ Biontech) and viral vector (Oxford/AZ- ChAdOx1 nCoV-19) vaccines. The Th1- response ( interferon-γ and tumor necrosis factor-α cytokine secretion by CD4+ T cells) and antibody production predominantly of IgG1 and IgG3 subclasses as well as CD8+ T cells mono, polyfunctional and cytotoxic phenotypes, will be also measured.

Throughout the COVID-19 pandemic, and to our knowledge there have been no studies looking systematically at the occurrence of MS relapses and their subsequent management, during the peak of the first wave of the pandemic. In this study we will explore how MS relapses were reported and managed during April - June 2020, compared to a control cohort who experienced a relapse during the same period in 2019 across 5 UK centers.

It was aimed to evaluate the respiratory functions of patients who were given respiratory rehabilitation, bed positioning and early mobilization, and the time of leaving the hospital.

In this study the investigators will explore the effect of the BNT162b2 COVID-19 Vaccine on semen analysis parameters among 75 fertile men. Fertile men will be regarded as such if they previously successfully impregnated their partners without the use of artificial reproductive technology, or men who previously had a normal sperm analysis exam by WHO criteria (2010). Those recruited will supply a single sperm sample 1-2 months following the second dose of the vaccination. In addition, the participants will fill a brief questionnaire with information regarding their medical and reproductive history. The investigators will examine the macroscopic and microscopic properties of the semen samples and compare them to the WHO semen analysis reference range in an attempt to ascertain whether the vaccine influences sperm parameters.

Pathogen-free, concentrated, pooled convalescent plasma has higher SARS-CoV2 antibody titers and neutralizing antibody activities, without requiring blood group compatibility that allows patient accessibility in a shorter time and has safe plasma characteristic.

The COVID-19 pandemic has caused changes in health care during pregnancy, childbirth and postpartum. Although adverse effects of COVID-19 on perinatal mental health have been documented, changes in the perinatal mental health care provided to women and their families are yet to be established. As a Task Force in Perinatal mental health and COVID-19 pandemic within RISEUP-PPD COST Action, we aim: (i) to identify policies, guidelines and protocols from different European countries concerning the provision of perinatal mental health care in face of COVID-19, and (ii) to select the best practices to alleviate the negative impact of COVID-19 on perinatal mental health. The survey will be conducted among experts in perinatal mental health who are members of the COST Action RISEUP-PPD and COST Action Devotion in 36 European countries. The experts will fill in the online survey designed for this study that includes a series of open-ended questions, checklists, and response ratings on a 7-point scale. The topic areas cover seven domains of interest: 1) mental health policies, guidelines, protocols, and documents; 2) mental health care practices; 3) best practices; 4) barriers; 5) resources; 6) benefits; and 7) short- and long-term expectations. Data analysis will be mainly a qualitative analysis of the experts' professional views and opinions about the policies, guidelines, protocols, and documents regarding perinatal mental health changes in their country. Additionally, a basic quantitative descriptive analysis will be conducted.
