Study to Assess the ART Impact on the Brain Outcomes. The ARBRE Study
HIV-1 InfectionCognitive ImpairmentThe ARBRE Study is an observational prospective trial aimed at investigating the impact of the therapy initiation with INTIs on brain outcomes according to the time of therapy initiation. Three study arms are considered: 1) Early treated HIV-1 infected patients (<3 months since estimated date of infection), 2) Regularly treated HIV-1 infected patients (>6 months since estimated date of infection), 3) Matched seronegative control group. Study assessments will be performed at baseline, 1 month and 12 months. Study assessments will comprise comprehensive evaluation of brain outcomes. They will include cognitive functioning, neuroimaging parameters, and functional outcomes.

Hepatitis D Virus Infection Among Hepatitis B Virus Surface Antigen Positive Individuals
HDV InfectionHBV InfectionGlobally, about 248 million people are chronic HBV surface antigen carriers, and about 5% of them also had hepatitis delta virus (HDV) infection as well. The prevalence of HBsAg in Egypt is intermediate (2-7%) . Hepatitis D virus (HDV) is an incomplete RNA virus that needs hepatitis B surface antigen (HBsAg) to help its replication. HDV is considered a subviral particle because it depends on HBV for its propagation. Combined HDV- HBV infection produces more severe liver affection than HBV alone. HDV infection leads to both of acute and chronic liver illnesses. Acute HDV infection can occur at the same time with acute HBV infection (coinfection) or can be superimposed on the top of chronic HBV infection. About 20% to 30% of coinfections of HDV and HBV in humans develop fatal fulminant hepatitis versus 2% of patients with acute hepatitis B mono-infection. Worldwide, Hepatitis D virus (HDV) infection present in more than 15 million people and it is endemic in the Middle East . In Upper Egypt, data about the prevalence, clinical, laboratory and virological characters of Hepatitis D virus-infected patients is rare. This study aims were: To estimate the prevalence of hepatitis D virus infection among HBsAg positive individuals. To determine the clinical, laboratory and virological characters of HDV infected patients.

Effect of Vitamin E-containing Dressing on Surgical Site Infection in Colorectal Surgery
Surgical Site InfectionA prospective, randomized study will be performed. Patients are randomized using a 1:1 allocation into 2 groups: patients receiving a vitamin E-containing dressing (group 1) and a conventional dressing (group 2). The primary outcomes variable will be occurrence of incisional SSI. Follow-up will be 30 days postoperatively.

Abdominal Closure Bundle to Reduce Surgical Site Infection in Patients Undergoing C-sections. Cesarean...
Surgical Site InfectionCesarean Section; InfectionThis study is a single center, randomized controlled trial investigating the use of an abdominal closure bundle to reduce surgical site infection in patients undergoing cesarean section. The abdominal closure bundle consists of surgeon repeat scrub, changing gown and gloves, as well as usage of new instruments for closure of fascia, subcutaneous tissue, and skin. Patients will be randomized to either abdominal closure bundle or normal operative procedure. Primary outcome is surgical site infection within 30 days of procedure.

Urinary Tract Infections Caused by ESBL-producing Enterobacteria
Urinary Tract InfectionsThe aim of this study was to compare the etiologic agents, the antimicrobial resistance rates, and the risk factors associated with a HA-UTI and CA-UTI among complicated and uncomplicated UTI patients in a tertiary-care hospital in Mexico. This study was performed according to the principles expressed in the Declaration of Helsinki with the approval of the Local Ethics Committee of the School of Medicine of the Universidad Autónoma de Nuevo León (UR14-004). All patients with a UTI and a positive urine culture (> 100,000 UFC/mL) from March to October 2015 were included. The study was carried out at the Hospital Universitario "Dr. José Eleuterio González" hospital, a tertiary-care teaching hospital in Monterrey, Mexico. Identification and susceptibility antibiotic assays were performed to all isolates from positive urine culture.

Next Generation Sequencing Detection of Lyme Disease
Lyme DiseasePediatric Infectious Disease4 moreNext Generation Sequencing is capable of sequencing millions of small strands of DNA from a single blood sample, potentially improving its sensitivity compared to PCR testing, which only detects predetermined larger strands of DNA. We will test the ability of NGS to detect Borrelia burgdorferi DNA in the blood of pediatric patients with Lyme disease. We will conduct an observational study of NGS testing on pediatric patients at all stages of Lyme disease. Study involvement will require a single study visit for clinical data collection and blood draw. We will enroll patients at all phases of suspected Lyme disease, collect clinically relevant information, and test for Lyme disease using Next Generation Sequencing and standard Lyme serologic testing. If the patient has multiple erythema migrans, Lyme meningitis, facial nerve palsy, arthritis, or carditis, a B. burgdorferi serum PCR will also be sent. Enrollment and Next Generation Sequencing blood draw will occur before or up to 24 hours after the first dose of antibiotics is administered. We will also study the impact of antibiotics on NGS testing by running the test 6-24 hours after antibiotics are started among a small subset of patients with a multiple erythema migrans rash. Collected data will be analyzed with basic descriptive statistics.

Long--term Outcome Analysis of Fracture--related Infections
Fracture-associated Infection (FAI)This retrospective analysis of medical records is to identify risk factors for treatment failures in fracture-associated infections (FAI) at the University Hospital Basel.

Acceptability of Telehealth Triage Using Robotic Systems in COVID-19
COVID-19Telemedicine3 moreThe overall objective of this investigation is to understand the patient response to a robotic platform used to facilitate telehealth triage in the emergency department during the COVID-19 pandemic. The COVID-19 pandemic has altered the manner in which emergency department triage is completed. Attempts at cohorting individuals with potential COVID-19 disease in order to prevent disease transmission to healthcare workers and minimize the use of personal protective equipment (PPE) have renewed interest in telemedical solutions as a method to triage and manage individuals with COVID-19. This investigation deploys a legged robotic platform to facilitate agile, highly mobile telemedicine to manage COVID-19 patients in the emergency department. The primary objective is to measure the patient response to interacting with these systems.

Epidemiological Survey of Hepatitis D Virus Infection in China
Observe and Describe the Prevalence of Hepatitis D Infection Among HBsAg Positive PeopleThis cross-sectional study will screen out hepatitis D virus-infected patients in HBsAg-positive people. Observe and describe the prevalence of hepatitis D infection among HBsAg positive people. The provinces of China are divided into 5 geographical areas (North, South, East, West and Central) to recruit patients according to the population density of each area. After statistical calculation, the total number of population needed is 3808.
