On January 30, 2020, the director general of the World Health Organization (WHO), following the advice of the Emergency Committee convened in accordance with the International Health Regulations (2005), declared that the COVID-19 outbreak started in Wuhan, China in December 2019, being a public health emergency of international concern. On March 11, the WHO declared the global SARS-CoV-2 pandemic. So far, in the absence of effective vaccines or antiviral drugs, efforts have focused on identifying cases and their contacts. Both the cases and their contacts are isolated for about 14 days with the intention of minimizing the spread of this infection and avoiding an increase in the number of affected. At the time of writing this new version of the protocol, we are immersed in the second wave of the COVID-19 pandemic. The projections of the natural history of the disease and the estimates of possible infections by SARS-CoV-2, carried out at the end of the first wave, made it possible to determine the feasibility of this second wave with the onset of cold from the autumn. Given this scenario, the University of Barcelona, together with the Gerencia Territorial del Área Metropolitana Sud, has planned to carry out, a study of seroprevalence and screnning of SARS-CoV-2 in the population of Universidad de Barcelona users. The results of this study will help to make preventive decisions in the face of SARS-CoV-2 infection at the UB, in relation to its teaching and administrative activities. In addition, this cross-sectional study can serve as the base study for a future follow-up study. HYPOTHESIS: The incidence of SARS-CoV-2 infection in the group of students and workers at the University of Barcelona is similar to the incidence in the general population. MAIN OBJECTIVE: - Estimate the incidence of SARS-CoV-2 infection in the UB community. - Estimate the SARS-CoV-2 seroprevalence infection in the UB community.
This is a retrospective observational study drawing on data from the Brigham and Women's Home Hospital database. Sociodemographic and clinic data from a training cohort were used to train a machine learning algorithm to predict length of stay throughout a patient's admission. This algorithm was then validated in a validation cohort.
188 healthcare personnel from 20 residential care homes (RCHs) will be recruited to assess the effect of 2-week implementation of Blended Gaming COVID-19 Training System (BGCTS) on RCH staffs' infection control practices. These clusters (RCHs) will be randomly allocated to two study groups (the intervention group, IG; and the control group, CG) to assess 1. whether more staff in the IG perform infection control practices (by on-site observations) than the staff in the CG after receiving BGCTS and 2. whether more staff in the IG have infection control knowledge, positive attitudes towards infection control, and self-reported compliance rates than the staff in the CG. 5 Hypothesis have been set up for this study: H1. After using BGCTS, a higher proportion of the staff in the IG will exhibit performance in complying with hand hygiene measures than those in the CG. H2. After using BGCTS, a higher proportion of the staff in the IG will exhibit performance in complying with other infection control practices than those in the CG. H3. After using BGCTS, a higher proportion of the staff in the IG will have high level of knowledge of infection control than those in the CG. H4. After using BGCTS, a higher proportion of the staff in the IG will have positive attitudes towards infection control than those in the CG. H5. After using BGCTS, a higher proportion of the staff in the IG will have a high self-reported compliance rate with infection control measures than those in the CG. Infection control practices conducted by RCH staffs will be measured through unobtrusive on-site non-participatory observations. RCH staffs' knowledge, attitudes about infection control practice, and self-reported infection control practices will be assessed via an electronic quiz.
The medical charts of all COVID-19 cases (n=1200) from 17 long-term care facilities in Montreal, Canada will be reviewed, to compare patients who survived to patients who did not survive. Through multilevel logistic regression, the risk of death will be estimated for institutional predictors of mortality, while controlling for individual risk factors. Individual covariates include clinical features (age, sex, Charlston comorbidity index, SMAF autonomy score, severity criteria) and medical treatments (IV fluids, anticoagulation, oxygen, regular opiates, corticosteroids). Aggregate covariates include epidemiological data (attack rates, timing of outbreak) and institutional characteristics (number of beds, air exchange per hour, presence of a dedicated COVID-19 unit at the time of outbreak, staff compliance to infection control measures, staff infection rates, understaffing, proportion of semi-private rooms, proportion of wandering wards and other special units).
This study is to obtain a comprehensive view of S. aureus adaptations in the infected human host and (i) to improve the understanding of the interface between antibiotic therapy, resistance development and virulence factor adaptation in S. aureus infected patients, and (ii) to adapt these findings into a more sustainable use of antimicrobials for therapy.
A cluster randomized controlled study of 40 primary care clinics in Northern Israel (20 intervention clinics, 20 usual care clinics) to evaluate the value of introducing a precision medicine/genomic approach/paradigm on the clinical and economical outcomes of the clinics. Intervention includes 3 elements: 1. DNA extraction and evaluation (up to the level of WGS); 2. Feces sample for microbiome study, 3. Wearable devices for continuous monitoring of body functions. Expected number of participants is 100,000 in each arm. Results will be calculated for a clinic as a unit and not for individuals (each clinic to be compared to "twin" selected clinic).
The main objective of this cohort is to characterize COVID-19 patients hospitalized in infectious disease department. The collection of clinical and biological data from start of hospitalization to long-term follow up will contribute to a better description of the patient care, to the identification of predisposition to complication related to the disease, and to the evaluation of the impact of different therapeutical strategies.
investigators will take stool and blood samples from two groups of humans :- 1-group A (healthy group negative Giardia or control group),2-group B (positive Giardia or case group)then investigators make estimation for vitamin D in both groups then investigators try to find if there is relation between vitamin D level and Giardia lamblia infections
Significant changes in gut microbiota was noted after the high-volume bowel preparation with PEG before colonoscopy. The dynamic changes were found to be short-term. However, the perturbation pattern of gut microbiota found after bowel preparation may link to metabolic syndrome and obesity. No study had investigated the supplementation of probiotic in this dynamic situation before. Here we proposed this study to fulfill the knowledge gap and also inquiry on the potential therapeutic strategy.1.To test the hypothesis of probiotic supplementation after bowel preparation alters the composition of gut microbiota in a short-term and long-term manner.2.To test the hypothesis of GI tract associated symptoms affected by probiotic supplementation after bowel preparation. 3. To test the hypothesis of clinical events, especially parameters of metabolic syndrome affected by probiotic supplementation after bowel preparation.
The aim of this study is to verify the quantitative and qualitative effect of Erbium dental laser therapy on microbial populations in carious lesions and to compare the laser therapy with traditional conservative therapies.
