Active clinical trials for "Communicable Diseases"

The purpose of this study was to explore the relationship between the transmission of respiratory diseases and the correct wearing of masks, as well as the factors affecting the correct wearing of masks. The research is beneficial to the prevention of respiratory diseases and moves the barrier of prevention and control forward. It is of great significance to COVID-19 's practical prevention and control.

The "COVID-19 infection self-test and alert system" (hereinafter referred to as "COVID-19 self-test applet") jointly developed by Beijing Tsinghua Changgung Hospital, Institute for precision medicine, artificial intelligence of Tsinghua University was launched on February 1，2020. Residents , according to their actual healthy situation, after answering questions online, the system will conduct intelligent analysis, make disease risk assessment and give healthcare and medical guidance. Based on the Internet population survey, and referring to the diagnosis and screening standards of the National Health Commission of the People's Republic of China, investigators carried out the mobile applet of Internet survey and registry study for the Internet accessible identifiable population, so as to screen the suspected population and guide the medical treatment.

Background: Several major studies have demonstrated the success of Truvada as pre-exposure prophylaxis (PrEP) in preventing HIV infection.The CDC guidelines recommend PrEP for people who are at elevated risk of HIV including men who have sex with men (MSM) and people who use injection drugs. People who are incarcerated bear a disproportionate of disease burden, including HIV. Furthermore, men who have been involved with the criminal justice system are more likely to engage in risky behaviors following their release, including condomless sex with partners of unknown serostatus, and injection drug use. The incarceration setting provides a place to engage men who may be at risk of HIV after they are released. Following release, community clinics, including the STD clinic at The Miriam Hospital (TMH) Immunology Center, that perform routine testing for HIV and other sexually transmitted diseases (STDs) may be ideal settings to engage vulnerable populations in care, including PrEP. Despite the demonstrated clinical efficacy of PrEP in reducing HIV transmissions, few clinical programs have piloted the use of PrEP in real-world settings, particularly criminal justice settings. Furthermore, studies demonstrate numerous challenges to PrEP uptake and adherence, including a lack of access or discontinuing care. Engaging at risk men in PrEP care before they leave prison and potentially lost to care during the transition may increase uptake, adherence, and retention. Objective: This study protocol will evaluate a clinical program that aims to prevent new HIV infections among recently-incarcerated men using a once daily dosing of tenofovir/emtricitabine (Truvada) as pre-exposure prophylaxis (PrEP). This protocol presents an overview of the clinical program, which uses standard-of-care clinical practices and Centers for Disease Control and Prevention (CDC) guidelines for prescribing and monitoring PrEP. Male inmates at the Rhode Island Department of Corrections (RIDOC) will be screened for HIV risk and, if eligible and interested, will be prescribed and given a one-month supply of PrEP shortly before their release, and receive follow up care at The Miriam Hospital (TMH) Immunology Center following their release.

Many patients who undergo vascular surgery to improve the blood flow to their legs are at risk of developing an infection in the surgical site and are then at risk of serious complications such as hospital readmission, failure of the surgical procedure and lower limb amputation. Surgical site infections may be reduced in high-risk patients by applying two commonly used antibiotics (gentamicin and vancomycin) into the surgical incision at the end of the surgical procedure. This will be compared to the standard of care treatment at London Health Sciences Center.

COHIVE is an observational cohort nested in four antiretroviral therapy research studies (ADVANCE - NCT03122262; D²EFT - NCT03017872; DolPHIN2 - NCT03249181 and NAMSAL-ANRS12313 - NCT02777229). COHIVE will include participants who are possible COVID-19 cases with symptoms or confirmed COVID-19 cases, and participants who agree to have a serology testing for SARS-CoV-2 regardless of COVID-19 history.

This study evaluates the use of Kagocel for the prevention of acute respiratory viral infections (ARVI) and influenza during the epidemic rise in the incidence of diseases in Russia in 2018 (epidemiology: the number of cases during the period of Kagocel administration and follow-up, bacterial exacerbations, the number of repeated episodes (reinfection), demographics of patients, safety, adherence to treatment) in students at risk due to stress, lack of sleep and fatigue.

This study generates robust, uniform clinical data across emerging COVID-19 strains to train ML/AI algorithms of the Sponsor's imPulse™ Una infrasound-to-ultrasound e-stethoscope for digital diagnostic feature synthesis of asymptomatic and symptomatic COVID-19 digital biosignatures for rapid and accurate adult and child mass screening.

Elderly people who have multiple health problems are at higher risk of illness from viral respiratory infections, such as influenza (the flu) and COVID-19. This is especially true for residents in long-term care because the usual methods of infection control (handwashing, mask-wearing, and distancing) are difficult to enforce due to the memory problems of many residents and the frequently shared common spaces. It can also be difficult to prevent the spread of viral infections within long-term care because many residents are unable to tell their caregivers when they are feeling ill. Also, some elderly people do not show typical symptoms of infection (like fever), instead they may suddenly become confused or weak. This study will test if a safe form of ultraviolet light (far-UVC) can be effective as an extra method of disinfection (in addition to usual manual cleaning) against airborne and surface viruses that can cause respiratory infections.

Eighty percent of nosocomial UTI caused by indwelling urinary catheters and so known-as catheter-associated UTI. CAUTI leads to multiple local and systemic derangements such as suprapubic pain, dysuria, cystitis, pyelonephritis, septicemia, and even septic shock. This study will be conducted up on 100 patients (50 per each group) with long term catheterization to assess efficacy of noble metal alloy coated catheter in reducing CAUTI.

Toxoplasmosis is a parasitic disease caused by Toxoplasma gondii and transmitted to humans through the consumption of raw or undercooked infected meat and / or by poorly washed vegetables. It can be transmitted from the pregnant woman to the fetus when infection occurs during pregnancy leading to congenital toxoplasmosis. Once infected, it is considered that the subject harbors cyst forms of the parasite in the muscles and brain for life with a risk of reactivation when immunocompromised. Recently, questions have been raised about the persistence of these cysts. Currently, only serological diagnosis can demonstrate the infection. This is done by detecting IgM and IgG directed against the parasite. Although humoral immunity is useful to diagnose toxoplasmosis, the cellular immunity is responsible of the main protective role during infection with the secretion of cytokines such as gamma interferon. In some situations, the serological diagnosis is limited: in immunocompromised subjects, some immunocompetent patients, in children with congenital toxoplasmosis, in which the anti T. gondii antibodies are no longer detectable. In order to have a true evaluation of the capacities of the immune system of each individual against T. gondii infection, it is necessary to evaluate the effector immune cells. The main objective of this protocol is to set up a cellular test with the stimulation of lymphocyte by T. gondii. For this objective, 20 subjects (10 positive, 10 negative for Toxoplasmosis serology) will be included. The secondary objective will be to compare the cellular diagnosis (evaluation by ELISA of the secretion of gamma interferon in the supernatant of cells stimulated by the Ag) with the serological diagnosis (IgG and IgM Alinity Abbott and Western blot LD Bio) in 3 groups of 10 patients: chronically infected patients, uninfected patients, patients with congenital toxoplasmosis as well as to assess the persistence or not of cellular and humoral immunity against T. gondii in 10 patients who had acute toxoplasmosis with a known date infection more than 10 years. Thus, 60 patients will be included for a total study period of 24 months. This study will thus allow the sponsor to have a clear understanding whether a subject is able or not to react against T. gondii infection.
