Filter by:The COVID-SRLF study will evaluate the sanitary safety of the French Intensive Care Society (FICS) annual meeting held in Paris Congress Center from June 9th to June 11th 2021 in the Coronavirus Disease 2019 (COVID-2019) pandemic situation. The primary objective is to determine the proportion of attendees with a positive antigenic COVID-19 screening test at day 7 (+/- 1) of their participation to the meeting. This rate will be compared to a cohort of health care professionals (medical doctors and paramedical professionals) from the same hospital ward as the attendees but who did not attend the meeting (stratified on centers, gender, age (< and >= 40 years, vaccination status (0, 1 or 2 doses) and socio-professional status (medical doctor, nurse, nurse assistant).
Recently, a new coronavirus disease 2019 (COVID-19) has appeared and caused an unprecedented pandemic which is considered as an urgent threat to health authorities worldwide. Several symptoms are observed which are fever, cough, shortness of breath, headache, runny nose, muscle pain, fatigue, arthralgia, sputum production, conjunctivitis, diarrhea. Susceptibility, genetics, systematic diseases, population, gender, and age are crucial considerations for the onset and progression of the viral infection. The patients suffering from asthma or pulmonary deficiency are at high risk of mortality. A metallopeptidase, angiotensin-converting enzyme 2 (ACE2) is considered as the functional receptor for SARS-CoV-2 and it was isolated from a COVID-19 patient. ACE2 was recognized in type I and type II alveolar epithelial cells in both nasal and oral mucosa, in the nasopharynx, in the smooth muscle cells and endothelium of vessels in the stomach and the skin, distinctly in the basal cell layer of the epidermis extending to the basal cell layer of hair follicles, and in the basal layer of the non-keratinizing squamous epithelium. In order to study the possible routes of SARS-CoV-2 infection on the oral mucosa, we investigated whether oral lesions mainly affect the tongue mucosa due to higher ACE2-expressing cell composition and proportion more than that in other oral tissues. Moreover, appearance of oral lesions were as a result of SARS-CoV-2 infection or as a side effect of certain drugs for COVID-19 treatment was evaluated.
This is a open label clinical trial to evaluate the efficacy, safety and immunogenicity of inactivated SARS-CoV-2 vaccines (Vero cell) in healthy people aged 3-17 years old in comparison with healthy population aged 18 years old and above
The study is a single-center, randomized and double-blinded trial to evaluate the immunobridging between different manufacture scales, lot-to-lot consistency of the Recombinant Novel Coronavirus Vaccine (Adenovirus Type 5 Vector)(Ad5-nCOV) in population 6-59 years of age. The immunobridging between different manufacture scales will be evaluated first, the immunobridging between different age groups will be evaluated second, the lot-to-lot consistency will be evaluated at last.
Rehabilitation status of children with cerebral palsy (CP) and anxiety of their caregivers during the covid19 pandemic were explored. 206 caregivers who voluntarily accepted to participate were administered the State-Trait Anxiety Inventory and evaluated about the rehabilitation status of their children.The anxiety levels of all caregivers were found high and the rehabilitation programmes of the children were interrupted.
Prospective study in a group of patients with COVID-19 pneumonia.
Prospective, randomized, controlled, multicenter, parallel clinical trial to assess the efficacy of seawater nasal wash to relieve COVID-19 and URTIs nasal symptoms and reduce intranasal viral load in subjects with mild to moderate COVID-19 disease and URTIs.
For an antiviral agent to act as an effective biological barrier on nasal mucosal surface, the formulation preferably has to be maintained on the site of action for several hours, and the nasal spray dispenser can be utilized for administering the solution to the upper respiratory tract. A "first-in-man" clinical study of the nasal spray containing anti-SARS-CoV-2 antibodies derived from bovine colostrum was conducted. The study on healthy volunteers was undertaken to evaluate how long the bovine antibodies would be maintained on the nasopharyngeal surface after administration of nasal spray. In addition, the study enabled to determine which of the two concentrations of antibodies should be used in the final nasal-spray formulation. The volunteers were followed up for 4h after administration of antibody spray and sampling was done at different time-points during this period. The concentration of antibodies from patient samples was measured using ELISA analysis. In addition, as this was a "first-in-man" study any adverse events following the administration of spray were also monitored.
Background The presence of the Covid-19 virus has been detected in tissues of various origins: nasopharyngeal swabs, sputum, bronchoalveolar fluid, blood, stool and anal swabs. However, it does not appear that the virus is excreted in the urine. The REACTing group (Research & Action Emerging Infectious Diseases) has demonstrated the presence of the virus in the conjunctiva and pleural fluid. This detection was made possible by carrying out quantitative, real-time RT-PCR and sequencing of the viral genes, which are currently the benchmark for the diagnosis of COVID-19. However, it is not known at this time whether the Covid-19 virus is present in joint fluid or in bone. However, some viruses have a particular bone tropism (Parvovirus B19, HHV6); others have joint tropism (parvovirus B19, HBV, HCV, rubella, HIV, HTLV-1). The presence in "orthopedic" tissues of the various coronaviruses (MERS, SARS, etc.) has never been evaluated in the past. However, cases of pulmonary contamination by coronavirus after bone marrow transplantation have been reported in the literature. A potential location at these levels could cause problems of different kinds. Rationale First, and concretely, a possible direct transmission by these tissues. The current English and Spanish national recommendations in orthopedics show a controversy as to the risk of intraoperative contamination during medical procedures generating aerosols, in particular those involving instruments at high speed (saw blade, reamer, drill). This transmission could also be a problem during bone marrow transplants, from the iliac crests, for example. Second, but hypothetically, Covid-19 could become quiescent at the level of the myelo-hematopoietic niches and reactivate at a distance, which could then explain the current interrogation on "absence of immunity" and cases of early revival in patients considered cured. This hypothesis is all the more likely since, always by analogy with Parvovirus B19 or HHV6, a recent alert on cases of myocarditis in children has been issued in Parisian pediatric hospitals and that treatment with tocilizumab, which blocks the action Interleukin 6 receptors, and initially used for joint manifestations of rheumatoid arthritis, appear promising.
Nursing home staff face multiple stresses during the Covid-19 pandemic including personal risk of infection, risk of transmission of the virus to residents and relatives, and risk of witnessing end-of-life scenarios under difficult contexts (absence of families). The hypothesis of this study is that the Covid-19 period is associated with an incidence of more than 30% of post-traumatic stress in nursing home staff.
