Filter by:The sudden Covid-19 pandemic has led all healthcare workers to adapt to an unprecedented situation by continuing to provide care while protecting themselves and their patients. Medical care with aerosolization systems is particularly of risk because of the strong propagation of the droplets they generate, especially during oral care. Considering the high risk of transmission of the SARS-CoV-2 virus in dental structures remain essential and still very challenging. The need to put in place care procedures to protect the nursing staff and patients is definitely more than necessary. Dental protection equipments against this emergent virus have progressively integrated daily practice, but, to the knowledge of the investigators, no study has precisely evaluated their efficiency. The main objective of this study is to estimate the risk of dental practitioners to be contaminated by SARS-CoV-2 during dental procedures with or without aerosolization procedures. For this, after their informed consent, vaccinated dental practitioners or practitioners with a positive covid serological tests of the dental department of Charles Foix hospital will receive individually forty to fifty COVID+ patients. COVID + patients will be included a maximum of one week after the diagnosis of the pathology. Patient care will be determined and performed according to standard practice as part of their standard management and without interference with the study. The usual measures to protect caregivers. The included patients will undergo an oral dental procedure either with aerosolisation or not. Then, SARS-CoV 2 samples will be collected using viral swabs on different spots, followed by detection and quantification by PCR. Swabbing will be achieved on: - The facial skin, nasal, ocular and oral mucosa of the practitioners. - The protection equipment of the practitioners (FFP2 masks, visors,surgical calot,gloves) . - The environment (dental Chair, surgical light, turbine, contra-angle, on the ground..) The presence of viral loads in areas used by COVID + patients will be evaluated by PCR after swabbing. The study will provide insight into the risk of SARS-CoV 2 contamination for practitioners performing dental procedures in COVID + patients. This risk will be assessed at the level of the facial skin and oral mucous membranes, which are the doors of entry of the virus. This study will thus make it possible to assess the protective capacity of the protection protocol implemented in investigators' department in this epidemic situation. This will be assessed depending on whether or not aerosolization is used, its type and the nature of the ventilation in the operating room.
Ice swimming is an increasingly common phenomenon in Poland. It has been confirmed that it has a beneficial effect on health by increasing the natural non-specific immunity to infections. In the face of the current Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) pandemic causing Coronavirus Disease 2019 (COVID-19), researchers decided to use a survey to check the incidence of COVID-19 among Polish ice swimmers, as well as recent ailments. Then, the researchers will compare the obtained results with epidemiological data for Poland.Researchers will also investigate the relationship between susceptibility to SARS-CoV-2 infection and the blood group and Rh factor among ice swimmers.
One investigational treatment being explored for COVID-19 is the use of convalescent plasma collected from individuals who have recovered from COVID-19 (Refs. 1-4). Convalescent plasma that contains antibodies to severe acute respiratory syndrome coronavirus 2 or SARSCoV-2 (the virus that causes COVID-19) is being studied for administration to patients with COVID-19. Use of convalescent plasma has been studied in outbreaks of other respiratory infections, including the 2003 SARS-CoV-1 epidemic, the 2009-2010 H1N1 influenza virus pandemic, and the 2012 MERS-CoV epidemic (Refs. 5-7). Although promising, convalescent plasma has not yet been shown to be safe and effective as a treatment for COVID-19. Therefore, it is important to study the safety and efficacy of COVID19 convalescent plasma in clinical trials. This guidance provides recommendations to health care providers and investigators on the administration and study of investigational convalescent plasma collected from individuals who have recovered from COVID-19 (COVID-19 convalescent plasma) during the public health emergency. This guidance also provides recommendations to blood establishments on the collection of COVID-19 convalescent plasma..
Of patients admitted to an internal medicine ward with internistic diagnosis/es together with COVID-19, substantial proportion has elevated liver enzymes. silymarin / silibinin (milk thistle extract) has been approved as an add-on therapy in various acute and chronic liver diseases; moreover, there is evidence to suggest that it's dual effect (anti-viral and immune-modulatory) might be of benefit in patients infected with SARS-CoV-2. As there is no effective/approved pharmacotherapy for COVID-19, a pilot study with Silymarine in hospitalised patients has been undertaken
This study will compare the safety and tolerability of lyophilized BNT162b2 presented in single dose vials to those of frozen-liquid BNT162b2 in multidose vials and determine whether the immune response is noninferior. Separately, the study will also describe the safety and immunogenicity of frozen-liquid BNT162b2 with lipid nanoparticle size at the upper end of specification and ready to use BNT162b2 (the immediate manufacturing precursor to the lyophilate). Additionally, the study will describe the safety and immunogenicity of an additional dose of frozen liquid BNT162b2 to participants who already received the 2-dose schedule of lyophilized BNT162b2. - 2-dose schedule (separated by 21 days) - At a dose of 30µg (as studied in the Phase 2/3 study C4591001) - In healthy adults 18 through 55 years of age - The duration of the study for each participant will be approximately 2 months (3 visits in total) - The study will be conducted in the United States
During the COVID-19 pandemic, patients with cancer are subject to multiple risks (e.g. frequent hospital visits, increased infection risk, more severe clinical course, discontinued cancer treatment etc.). Patients undergoing cancer therapy are also faced with several Quality of Life - impairing side effects. In the case of a positive COVID-19 cancer patient, the need and intensity of treating must be weighed against the possible higher risk of developing severe complications in the course of a COVID-19 infection. Nevertheless, both for COVID-19 positive and negative patients who will continue or discontinue cancer treatment throughout the pandemic, providing supportive care is more important than ever. Digitally monitoring patient-reported outcome measures (PROMs) could offer a solution to improve the supportive care measures during cancer treatment, and certainly in times of COVID-19. Digitalized PROMS could significantly contribute to improved communication, patient satisfaction, supportive care, monitoring of cancer treatment, and detection of problems. To date, clinical trials investigating the benefits of digital PROMS in patients with cancer during the current COVID-19 pandemic are lacking. At the Jessa Hospital, the investigators already have experience in collecting PROMs via a digital platform (Awell Health) since 2019 for patients with breast cancer undergoing chemotherapy using validated QoL questionnaires. The overall aim of this project is to prospectively evaluate the impact of a COVID-19 infection on the severity of the cancer therapy-related complications and the QoL of patients with cancer undergoing chemotherapy using a digital PROMs-platform.
This is a Phase 1/2/3 study in healthy children. Dependent upon safety and/or immunogenicity data generated during the course of this study, and the resulting assessment of benefit-risk, the safety, tolerability, and immunogenicity of BNT162b2 in participants <6 months of age may subsequently be evaluated.
The purpose of this study is to evaluate the potential for MDW and other CPD parameters (measured with CBC-DIFF) to identify COVID-19 diseased adult individuals presenting to the hospital with symptoms suggestive of COVID-19 or respiratory infection and whose standard of care includes CBC-DIFF and microbial testing.
This study was designed to determine, in a screening situation within the framework of university preventive medicine, the prevalence of positive anti-SARS-Cov 2 serology among the staff of the University of Reims Champagne-Ardenne. The serological tests chosen will allow systematic detection of anti-SARS-CoV-2 IgM and anti-SARS-Cov-2 IgG to assess the moment of potential contamination prior to resumption of occupational activity.
Patients on haemodialysis are at higher risk of getting a severe form of COVID-19 if they become infected. Vaccinations are soon to arrive and offer great hope of controlling the current pandemic. It is likely that patients on haemodialysis will be amongst the first people to be offered vaccination against COVID-19 when they become available. While any vaccines offered to these patients will be safe to receive, the effectiveness of the vaccines at giving immunity to being infected with COVID-19 are not known as they have not been explicitly tested in patients on haemodialysis. This study will involve having 3 blood tests to test for an antibody response following vaccination for COVID-19. The first will be 1 month after the first vaccination dose to look at the initial antibody response and the second and third will be 1 month and 6 months after the second vaccination dose.
