COVIDSARS-CoV 2Seroepidemiological Study of SARS-CoV-2 Infection in Population Subgroups in the State of São Paulo

CORE Study COVID-19
Coronavirus Infection (COVID-19)This is a Brazilian version of the Clinical Characterization Protocol for Serious Emerging Infections (ISARIC/WHO ). This is a standardized protocol for the rapid, coordinated clinical investigation of Coronavirus disease (COVID-19). Patients with acute illness suspected to be caused by emerging will be enrolled. This protocol has been designed to enable data to be prospectively collected.

Prognostic Value of Flow-mediated Dilation in Hospitalized COVID-19 Patients
Covid19SARS-CoV InfectionThis study will evaluate the associations between vascular parameters and clinical outcomes in patients hospitalized with COVID-19. The vascular function and structure of individuals with COVID-19 admitted to the General Hospital of the University of Sao Paulo will be assessed in the first 72 hours of hospitalization. Then, participants will be followed up until hospital discharge/death. Logistical regressions will be run to evaluate if vascular function/structure can predict ICU admissions, intubation, thrombosis or death.

Vitamin D Estimation With Giardia Lamblia Infections
Giardia Lamblia Infectioninvestigators 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

Intensive Care Unit Acquired Infections in Patients Colonized With Extended Spectrum Enterobacteriaceae...
Ventilator Associated PneumoniaBacteremia2 moreWorldwide emergence of extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-E) had become a major problem in ICU, with at least 10% of incidence at the admission in Europe. A systematic rectal swab is used in 70% of French ICU to detect intestinal ESBL-E carriage The relationship between intestinal carriage and ICU-acquired infection is not perfectly known. The investigators conducted a five years study monocentric retrospective observational cohort in patients with presence of extended-spectrum β-lactamase-producing Enterobacteriaceae in systematic rectal swabs to investigate which type of infections and which bacteria are involved. The investigators also collect data about antibiotherapy used to treat these infections.

β-lactam Use in Single-stage Exchange of ProstheTic Infections (Knee / Hip) in a Center of Reference...
Infected of Hip or KneeprosthesisAccording to the official recommendations, infected prosthesis can be surgically treated by one or two-stage replacement. In Strasbourg, the investigators only perform one-stage surgery, which means that the new materiel is put directly into an infected site. To prevent re-infection, probabilist antibiotherapy has to be started the earlier as possible and to have the larger specter as possible. Official recommendations don't specify the best choice of antibiotherapy and let prescriptors make choice, according to the local epidemiology and patient's history. In Strasbourg, the investigators systematically start an antibiotic against cocci gram positive: daptomycin. Sometimes, the investigators add tazocillin, a broad-spectrum β-lactam against bacillus gram negative. To determine if the investigators use the second one, they focalized on the presence of fistula or not. Indeed, enterobacteriae from gastro-intestinal tractus are also found on the skin and can move to the peri-prosthetic site if a fistula is created. The major disadvantage of this board-spectrum antibiotic is the selection and creation of resistant bacteriae, which can be responsible of failure, re-infection, or just spreading on the environnement. The primary purpose is to evaluate retrospectively the prescription of tazocillin, judging it's necessity thanks to antibiograms performed on samples taken during surgery. The aim is to evaluate if the criteria " fistula or not " is a good one to guide the prescription of board-spectrum β-lactam. Secondary purposes are to find the etiology of failures ( bacteriological failure or re-infection with a new pathogen), evaluate the apparition of multi-drug resistant bacteriae and infections they are responsible for, looking for others criterias which could help the investigators to choose the probablist antibiotherapy

Validation of a Prediction Score for Recurrent C. Difficile Infection: Implementation for Treatment...
Clostridium Difficile InfectionThe objective of the present study is to derive a high-risk R-ICD prediction rule and a prospective implementation of this prediction rule.

Early Diagnosis of Intracranial Infection After Craniotomy
Intracranial; InfectionPsychosis1 moreIntracranial infection are serious complications postoperatively in neurosurgical patients. Early identification of these complications is essential to minimize the mortality and moribidy. The aim of this study is observe the postoperative dynamic changes of body temperature (BT), procalcitonin (PCT), C-reactive protein (CRP), and white blood cell (WBC) count, and evaluate whether the use of two or more of these markers may improve the diagnostic accuracy of intracranial infection.

The Status of Helicobacter Pylori Infection Among Children Visiting Assiut Children Hospital
Helicobacter Pylori InfectionThe aim of this study is to estimate the prevalence of Helicobacter pylori infection among Egyptian children attending to healthcare facilitates using different diagnostic tools.

Gut Microbiota Association With ESBL-E Colonisation and Subsequent ESBL-E Infection
Extended Spectrum Beta-Lactamase Producing Bacteria InfectionMicrobial Colonization1 moreAntimicrobial resistance is a major threat worldwide and extended-spectrum beta-lactamase producing Enterobacteriales (ESBL-E) are a leading cause because of their wide dissemination. Gut microbiota seems to be correlated with multi-drug resistant organism carriage. This study thus aims to analyse the correlation between gut microbiota, ESBL-E fecal carriage and subsequent infection.
