Filter by:Filter facepiece respirator (FFR) is a critical equipment to prevent the transmission of respiratory tract infection disease especially the dreadful corona virus 2(SARs-CoV-2).The N95 mask is the prototype of high efficiency protective device and can effectively protect airborne pathogens of less than 0.3 μm by more than 95%. It is tightly fit and had high filtration capacity. The widespread pandemic of COVID-19 leads to greater requirement of FFR. A rising in demand would greatly exceed current productive capabilities and stockpiles and would almost certainly result in a robust shortage. In order to solve these problems, our team had invented a new type of half-piece respirator made from silicone and assembled with hepa or elastostatic filter . A variety of methods have been used to evaluate this new device, including qualitative fit test with Bitrex® test kit and filtration test.
This case series describes the clinical characteristics, treatment and outcomes of patients with laboratory confirmed COVID-19 admitted to a 35 beds intensive care unit of a tertiary hospital in Northeast Brazil.
In our hospital's Infectious Diseases and Clinical Microbiology service, patients who have been hospitalized due to Covid -19 infection have a musculoskeletal pain and headache during this process, and 466 patients will be recruited to compare them with the pre-disease state of the patients and to evaluate the pain status of the patients after treatment.
This is a study to test a new vaccine (Covax-19) against COVID-19. COVID-19 is a potentially deadly disease that is caused by a new strain of coronavirus called SARS-CoV-2. To date, SARS-CoV-2 has infected over 4 million people worldwide resulted in the deaths of over three hundred thousand people.
This is a single center observational autopsy study, conducted during the first wave of the coronavirus disease (COVID-19) pandemic in France. The main objective is to evaluate brain damages in patients who died from COVID-19 to inform the cause of death. Investigations include macroscopic and histology examinations, and virology analyses.
In this study, the investigator aims to measure stress, anxiety, mood, life satisfaction measures among elite athletes during COVID-19 and measure the relationship between these measures and the changes in training characteristics in elite athletes during the COVID-19 pandemic.
During COVID-19 epidemic, hydroxychloroquine was proposed and authorized as a possible key agent in the treatment of COVID-19 hospitalized pneumonia, including in France. Gautret et al. proposed the combination regimen with azithromycin. However only one study reported the interest of azithromycin alone. Retrospective study reporting the impact of the anti-infective agents used during the pandemic in a tertiary care hospital, using azithromycin with or without hydroxychloroquine.
As a result of the pandemic, hygiene and distancing rules must be followed in Health care/ rehabilitation clinics to ensure the safety of patients and staff. This has led to extensive changes in the therapy processes, including a reduction in group sizes and maintaining distances within the groups, resulting in a reduction in the range of therapies available to individuals, since the number of employees remains unchanged and cannot be increased at will and in the short term due to the lack of qualified staff. In order for the treatment/rehabilitation goals to be achieved nonetheless, new forms of implementation of therapy programs must be developed in addition to organizational adjustments. Digitalization can be a significant support in this respect. The majority of patients in psychosomatic rehabilitation possess smartphones, meaning that the necessary infrastructure for the utilization of digital offers is available and can be used to the greatest possible extent. The use of digital measures within the therapeutic services supports the independence of the patients, as they can use the digital offers independently and flexibly in their own time. How should Health care/rehabilitation services be designed in light of the SARS-CoV-2 pandemic and which services have the potential to buffer future crises: What general recommendations can be derived for the design of such services for routine care? What are support measures to encourage social participation and return to work?
Early inhibition of entry and replication of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a very promising therapeutic approach. Polyclonal neutralizing antibodies offers many advantages such as providing immediate immunity, consequently blunt an early pro-inflammatory pathogenic endogenous antibody response and lack of drug-drug interactions1-3. Because a suboptimal endogenous early antibody response with regard to SARS-CoV-2 replication in severe cases is observed, neutralising antibody treatment can be very interesting for patient with COVID-19 induced moderate pneumonia4,5. Convalescent plasma to treat infected patients is therefore an interesting therapeutic option currently under evaluation. However, the difficulties of collecting plasma and its safety aspects are not adapted to many patients. A new polyclonal humanized anti-SARS-CoV2 antibodies (XAV-19) is being developed by Xenothera, which can be administered as intravenous treatment. XAV-19 is a heterologous swine glyco-humanized polyclonal antibody (GH-pAb) raised against the spike protein of SARS-CoV-2, inhibiting infection of ACE-2 positive human cells with SARS-CoV-2. Pharmacokinetic and pharmacodynamic studies have been performed in preclinical models including primates and a First In Human study with another fully representative GH-pAb from Xenothera is ongoing in volunteer patients recipients of a kidney graft. These studies indicated that 5 consecutive administrations of GH-pAbs can be safely performed in humans. The objective of this 2-steps phase 2 randomized double-blind, placebo-controlled study is 1) to define the optimal and safety XAV-19 dose to administrate in patients with COVID-19 induced moderate pneumonia ; 2) to show the clinical benefit of selected dose of XAV-19 when administered to patients with COVID-19 induced moderate pneumonia.
The aim of the SARS-CoV-2-CZ-Immunity study is to determine the time profile of the presence of antibodies against SARS-CoV-2 in blood plasma by quantification of antibodies or performing a rapid test in COVID-19 cured patients.
