Study for Antibiotic Impregnated Calcium Sulfate Beads as Prophylaxis for Surgical Site Infection...
Surgical Site InfectionThe CDC quotes a rate of wound infection of 2-5% for inpatient surgery. Patients undergoing a vascular operation, however, are generally at an increased risk of wound infection with rates often close to 5-10%. Groin incisions are an additional risk factor for surgical site infections, with rates of wound infection being quoted from 10-15%, and even as high as 30% in high risk patients. The use of implantable calcium sulfate beads mixed with antibiotics may help to lower the rate of infection in these high risk patients.
Immune Response to BCG Vaccination in Neonates Born to HIV and LTBI Infected and Non-infected Mothers...
HIV InfectionsNeonatal Infection2 moreMaternal infections affect the basal immune status of neonates. One of the possible mechanism is the fetomaternal microchimerism, in which some cells and active substances are exchanged bi-directionally between maternal and fetal circulation through placenta. Even in the absence of a direct (vertical) transmission of pathogens to fetuses, certain infections make the neonates more prone to allergies and some adverse events of early vaccinations. We postulate that the basal immune status of neonates born to HIV and LTBI infected mothers is primed by gestational exposure to immunological active molecules, which could results in an altered response to early BCG vaccination. Transcripts expression identified by RNA sequencing are compared between sets of mother-child and their respective umbilical cord blood, and between groups of infected and non-infected pairs.
Host RNA Profiles to Detect Infections in Young Infants
Bacterial InfectionsUrinary Tract Infections8 moreThis study seeks to identify and test host RNA expression profiles as markers for infections in young infants. Preliminary studies have shown high sensitivity and specificity for the discrimination of bacterial from non-bacterial infections in children, but the method has only been investigated in a limited number of young infants. The study aims to include 65 young infants with serious bacterial infections. The samples will be analysed by RNA sequencing. New diagnostic tools may help reduce unnecessary antibiotic treatment, antibiotic resistance, side-effects, hospitalisation and invasive procedures.

SCREENING AND SEROEPIDEMIOLOGY OF SARS-CoV-2 INFECTION AT THE UNIVERSITY OF BARCELONA: A CROSS-SECTIONAL...
SARS-CoV-2 InfectionBACKGROUND: On January 7, 2020, the Chinese authorities identified as the agent responsible for the cases of atypical pneumonia of unknown etiology a new type of virus of the Coronaviridae family that has subsequently been named SARS-CoV-2, whose genetic sequence was shared by Chinese authorities on January 12 (taxonomy ID: 2697049). 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.

Index Individuals in SARS-CoV-2 Prevention Research Studies (COVID-19 Index Individuals Companion...
SARS-CoV-2 InfectionCOVID-192 moreClinical trials of prevention modalities for Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection and coronavirus disease (COVID-19) and pneumonia are underway under separate protocol(s) for close contacts (i.e., household contacts, [e.g.,3502]) of infectious (index) individuals (3502-01). Characterizing the index individuals within households will ascertain the risk of exposure for the contact participant. These data will be used to strengthen the precision of efficacy estimates. This ancillary observational study will assess the cofactors for infectiousness among index individuals whose close contacts are enrolled in COVID-19 prevention clinical trials. Additionally, this study will assess post-acute sequelae of SARS-CoV-2 infection in index individuals that are more than two weeks past their initial diagnosis.
Cutaneous Manifestations of Coronavirus Disease 2019(COVID-19).
Cutaneous ManifestationsSkin Manifestations6 moreAn outbreak of Corona virus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-coV-2) occurred in Wuhan city, Hubei province, China in December 2019. Pulmonary health has been the main focus of studies of COVID-19, current articles show that cutaneous signs appear in COVID-19 patients, their identification may be vital to early diagnosis and lead to possible better prognosis in COVID-19 patients

Seroprevalence Study of CoV-2-SARS (COVID-19) Infection in Patients With Chronic Inflammatory Rheumatic...
COVID-19SARS-CoV Infection4 moreThe prevalence of SARS-CoV-2 infection in chronic inflammatory rheumatic diseases has not yet been widely reported, and has been evaluated only in symptomatic patient samples. The proportion of asymptomatic or mildly symptomatic patients is unknown, in patients who share common symptoms with CoV-2-SARS infection. Our objective is to describe the prevalence of seroconversion to CoV-2-SARS by consecutive screening in routine care of patients with chronic inflammatory rheumatism with serological testing
