Filter by:An Open Comprative Study of the Prophylactic Efficacy and a Non-comparative Study of the Immunogenicity and Safety of the Inactivated Whole-virion Concentrated Purified Coronavirus Vaccine (CoviVac) Produced by FSBSI "Chumakov Federal Scientific Center for Research and Development of Immune-and-Biological Products" for Adults Aged 60 Years and Older
The goal of this observational study is to evaluate new non-invasive passive surveillance technologies, Level 42 AI imPulse™ for the detection of COVID-19 in asymptomatic and symptomatic individuals over age of 18 undergoing COVID-19 screening and testing at BAMC Ft Sam Houston, TX; with and without COVID-19. The hypotheses are: (H1) The imPulse™ Una e-stethoscope has at least a similar discriminative and detection ability among symptomatic and asymptomatic COVID-19 carrier versus those not infected compared to gold standard RT-PCR. Based on these promising studies, we will operationalize and deploy the imPulseTM Una e-stethoscope and other associated technology form factors into DoD use-cases. (H2) In the mid to long-term, this approach will also be explored as a diagnostic system to explore pursue the physical (structural and mechanical) properties of cells and tissues that maintain normal cell behavior (motility, growth, apoptosis), and the critical importance of the ability of cells to sense and respond to mechanical stresses, which will be operationally critical for assessment of both traumatic and unconventional exposures in austere environments. Participants will: - Be consented; - Be screened for COVID-19 symptoms according to BAMC's current screening procedures; - Have study data collected; - Complete a COVID-19 symptoms questionnaire; - imPulseTM Una e-stethoscope examination will be conducted; - Participants will be compensated for completing all study requirements. (Active-Duty personnel must complete the study procedures while off-duty in order to receive compensation.)
Brief Summary: The main objective of this activity is to assess the effectiveness of different messaging strategies (factual, narrative, mixed and a control) to promote COVID-19 adult vaccination.
Background Anal fissure is one of the most common anorectal problems. After an outbreak of coronavirus disease (COVID-19) has rapidly spread from China to almost all over the world, it nearly affected all countries. In spite of its typical presentation in the form of fever, cough, myalgia, fatigue and pneumonia, other GIT manifestations were reported. We found some of COVID-19 survivors who had complained from anal fissure problem. The aim of this study was to report the prevalence of acute anal fissure among COVID-19 patients, its possible risk factors and outcome. Methods This is a retrospective cross-sectional study which was conducted over three months from the start of September 2020 to the end of November 2020 at Mansoura university isolation hospital, on COVID-19 patients' who were diagnosed with anal fissure. Those who survived and were discharged home safely were telephone called to pick up whether they suffered from any symptoms of anal pain, difficulty in defecation suggesting anal fissure, in order to identify their outcomes, the risk factors for anal fissure development and how they were managed. Results A total of 176 patients were enrolled in this study. Patients were categorized into two groups. The first group included patients who developed anal fissure (n=65) and the 2nd group included patients who did not develop anal fissure (n=111). No significant difference was noted in demographic data apart from the age which was younger in the fissure group. The incidence of anal fissure was 36.9% of total population. The majority of patients' anal fissure problem resolved spontaneously after patients improved from the COVID symptoms without receiving any treatment (43.1%). Conclusion Anal fissure is quite common problem after COVID-19. Young and middle age patients are more vulnerable to develop anal fissure after COVID-19 infection.
Open prospective non-comparative study of safety and tolerability of the drug (GamCoviMab) with the description of the parameters of the therapeutic efficacy in patients with confirmed COVID-19 diagnosis.
The goal of this clinical trial is to assess the immunogenicity, efficacy and safety of the Convacell vaccine in healthy adult volunteers aged 18 years and older. The main questions it aims to answer are: - To assess the immunogenicity and safety of single and double dose intramuscular administration of the Convacell vaccine; - To assess the epidemiological effectiveness of the Convacell vaccine in the prevention of SARS-CoV-2 infection and development of severe COVID-19 compared with placebo when single or double intramuscular injection.
The goal of this observational study was to explore the complex relationship between changes in the intestinal microbiome and serum metabolites in patients with novel coronavirus infection and acute pancreatitis. The main questions it aims to answer are: Question 1: The changes of intestinal microbiota and serum metabolites in patients with novel coronavirus infection and acute pancreatitis. Question 2: The relationship between the changes in the intestinal microbiome and serum metabolites. Participants will be recruited according to certain criteria. The investigators plan to recruit 4 groups of 30 volunteers, 120 volunteers in total. It is divided into (a) AP patients without COVID-19 (normal group) (b) AP patients with COVID-19 (treatment group) (c) patients with COVID-19 infection (control group) (d) normal healthy people. The basic information of subjects, including age, sex, address, and enrollment time, was collected after enrollment. After completing the relevant preparations, start the experiment. First of all, the sample collection and detection. Blood samples were taken from 2-3ml of blood (biochemical tube) after admission or in the morning of the next day, centrifuged at 3000 rpm for 3 minutes, and stored at -80℃ within 1 hour after taking the serum; Fecal samples are stool samples retained after admission and before antibiotic use. Fecal samples need to be stored at -20℃ within one hour after collection and transferred to -80℃within 24 hours. After the retention of samples, the retained stool samples shall be tested for bacterial flora, and the blood samples shall be tested for serum metabolomics. After the test, the investigators will use the statistical software SPSS 22.0 for statistical analysis. At the same time, in order to determine the correlation between intestinal flora and clinical parameters, the investigators will use Permutation analysis of variance (PERMANOVA) to process the data.
This study aims to design a Convolutional Neural Network (CNN) and apply an attention model to help differentiate pneumonia due to Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), pneumonia due to other viruses/bacteria, and normal chest x-ray (CXR) in clinical practice. A bank of digital chest images from a high-complexity health facility in Cali, Colombia, was used.
Awake prone positioning has been reported to improve oxygenation for patients with COVID-19. Awake timed and repositioning is a novel method to improve patients' compliance and prolong the prone time. This study aims to explore the impact of timed prone and repositioning on the intubation rate and prognosis of COVID-19 patients with hypoxic respiratory failure.
This study aims to observe the impact of COVID-19 infection on the reproductive function and assisted pregnancy outcome of infertile couples undergoing assisted reproductive technology and to determine which factors are related to the clinical pregnancy rate. A multicenter, prospective, observational cohort study was adopted. Infertile couples who met the selection criteria were included in this study, the SAS anxiety self-rating scale was filled out, the basic situation was observed, and blood samples and related tissues were collected for testing. Relevant reproductive function, laboratory, clinical, and psychological indicators were collected, and the correlation between the above indicators and the outcome of the ART-related pregnancy were analyzed.
