Filter by:In December 2019, a new pandemic emerged, the COVID-19 disease caused by a SARS-Cov-2 virus. One of the most common symptoms of COVID-19 is mainly respiratory failure and patients requires assistance by mechanical ventilation. Ventilator-associated pneumonia (VAP) is a risk of this assistance. Since the beginning of the pandemic, Standard of care have evolved with new data. The prevalence of these VAPs seems significantly higher in the population of patients with ARDS COVID-19 (40-50%) and their ecology seems to have evolved over time, particularly in terms of bacterial resistance. Investigators want to describe and compare this evolution of bacterial and fungal ecology as well as identify potential risk factors that may be associated with these changes in ecology during different waves.
This study was conducted to examine the use of integrative treatment methods by individuals undergoing Covid-19. In this study, which was designed in the qualitative and phenomenological type, the criterion sampling method was used and 12 people were included in the sample.
Popular topic: Clinical study on immunogenicity and safety evaluation of sequentially enhanced immunity with recombinant Novel Coronavirus vaccine (CHO cells) Research purpose:Main purpose:To evaluate the immunogenicity of recombinant Novel Coronavirus vaccine (CHO cells) after sequential booster immunization in populations vaccinated with two doses of marketed Novel Coronavirus inactivated vaccine.Secondary purpose:To evaluate the safety of recombinant Novel Coronavirus vaccine (CHO cells) after sequential booster immunization in populations vaccinated with two doses of marketed Novel Coronavirus inactivated vaccine. Overall design:An open experimental design was used in this study Study population:The study involved people 18 years of age and older. Test groups: All subjects recruited must have received two doses of Novel Coronavirus inactivated vaccine for 3 to 13 months (the interval between booster and basic immunization is divided into 3 groups:120 subjects at 3-4 months (91-120 days), 6-8 months (181-240 days) and 11-13 months (331-390 days) were vaccinated with one dose of recombinant Novel Coronavirus vaccine (CHO cells).
the SARS-CoV2 pandemic has led to a major reorganization of the French Hematology and stem cell transplant departments since march 2020. Since the allogeneic stem cell transplant cannot be delayed especially when patients with hematological malignancies are in a fragile remission, risking relapse at any time, the necessity to maintain safe hematopoietic stem cell (HSC) donations from match unrelated or family donors appears rapidly mandatory during the pandemic period. To increase the safety of voluntary donations, a SARS-CoV2 Polymerase Chain Reaction test has been recommended to donors by regulatory agencies. However, due to the lack of homogeneity of care at European level, some countries do not require SARS-CoV-2 testing in asymptomatic donors. In this case, the test is performed on additional EDTA tube accompanying the graft on arrival or in the case of a missing tube (not collected or forgotten), on few milliliters of the HSC graft. This circuit had the consequence of forcing the clinicians to wait for the test result before starting the patient's conditioning regimen. The graft being already collected and received at the transplant center, and the conditioning regimen lasting on an average of 5 days, this resulted in its conservation during this minimum period and therefore its freezing by the associated cell therapy unit. However, this practice has so far been exceptional regarding allogeneic transplants, which are primarily freshly infused to ensure to the recipient the highest viability and functionality of stem cells. Since the entire freezing-thawing and washing process may impact cell viability and delay the patient's aplastic recovery, this study aimed to analyze the results of one year of allogeneic transplants infused after freezing in terms of graft quality after thawing and clinical consequences.
The overall project aim is to study outcomes after COVID-19 and influenza hospitalisation from 2016 - 2021 by retrieving data from the main social security carriers in Austria for the years 2010-2018
Objective: to assess the perinatal results in Uruguay during the semester of successful control of the COVID 19 pandemic to evaluate the impact of the crises in the public and private sub sectors of the Health System. Methodology: An analytical observational study was carried out, comparing the semesters from March 15 to September 30, 2019 (year prior to the COVID 19 pandemic) with the same period 2020 (year of the COVID 19 pandemic), in the 2 sub sectors of public and private health care.
Since the onset of COVID-19, recommendations suggest the use of neuraxial anesthesia, if possible, over general anesthesia for cesarian section to avoid the risks of aerosolization associated with tracheal intubation and extubation. But the safety of performing spinal anesthesia is unclear especially for post spinal hypotension, during the presence of active infection with COVID-19. Since at the beginning of the pandemic a few studies reported significant hypotension during epidural anesthesia in COVID-19 pregnant women, there was a controversial discussion about the safety of regional anesthesia was started. In this study we aimed to find if spinal anesthesia is safely recommended anesthesia type for COVID-19 obstetric patients. 249 patients with PCR confirmed COVID-19 for cesarean section undergoing spinal anesthesia in Ankara City Hospital, Ankara assessed in this retrospective study to find if the hypotension is the risk factor for the COVID-19 patients.
Observational program, double-blind, placebo-controlled to study the preventive efficacy of the BiVac polio (Oral polio vaccine, divalent, live attenuated of types 1 and 3 vaccine against the incidence of acute respiratory infections, including COVID-19
Objective: Veno-venous ECMO has been used as a rescue therapy for patients with severe ARDS associated to influenza A H1N1 and COVID19 viral pneumonia. Little is known about outcome of these patients who required extracorporeal support. Research question: To compare outcome of patients who required VV ECMO for Covid19 and H1N1 associated ARDS
Eligible participants who were active beneficiaries of a large insurer living in Pennsylvania were sent an email encouraging them to download the contact tracing app in Pennsylvania, COVID Alert PA. Participants will be randomly assigned to one of four conditions in a 2 (Self-benefit vs. Other-Benefit) x 2 (Social Norms Present vs. Social Norms absent) design. All participants received an email that said : "COVID Alert PA is the official Exposure Notification App from the Pennsylvania Department of Health. Join Penn Medicine in the fight against COVID-19 and download COVID Alert PA today!" ---Investigators manipulated the content here--- "The app uses Bluetooth to sense when one person is in close contact with another person with the app. If someone tests positive for COVID-19, and they decide to upload the information to the health department, people who have the app and who have been in contact with them will be alerted. If you are interested in downloading the app, please click COVID Alert PA. We appreciate you joining our efforts. Together we can beat COVID-19!" In the Other-Benefit condition, it said: "It can help you reduce your risk of unknowingly spreading the virus to your friends, family, and larger community." In the Self-Benefit condition, it said: "It can help you determine where and when to get testing, and how to get care if you need it." In the Social Norms Present condition, it said: "Over 650,000 Pennsylvanians have already downloaded the app!" In the Social Norms Absent condition, it said the statement about social norms above. Participants who do not open the initial email received a follow-up email.
