Active clinical trials for "Virus Diseases"

Acute upper respiratory tract infection(AURI) is common in children, and viral infection is the main cause. However, several children with viral infection are easy to suffer from secondary bacterial infection, and the mechanism is unclear.

Hepatitis E Virus (HEV) infections are emerging in the Western world with a predominance of HEV genotype (gt) 3. Except for age older than 50 years, male gender, chronic liver disease and immunosuppressed status, no correlators with clinical outcomes have been identified so far. With this study, we want to examine viral factors associated with the morbidity and mortality of HEV infections in Belgium as well as find correlators with clinical outcomes.

Background Anal fissure is one of the most common anorectal problems. After an outbreak of coronavirus disease (COVID-19) has rapidly spread from China to almost all over the world, it nearly affected all countries. In spite of its typical presentation in the form of fever, cough, myalgia, fatigue and pneumonia, other GIT manifestations were reported. We found some of COVID-19 survivors who had complained from anal fissure problem. The aim of this study was to report the prevalence of acute anal fissure among COVID-19 patients, its possible risk factors and outcome. Methods This is a retrospective cross-sectional study which was conducted over three months from the start of September 2020 to the end of November 2020 at Mansoura university isolation hospital, on COVID-19 patients' who were diagnosed with anal fissure. Those who survived and were discharged home safely were telephone called to pick up whether they suffered from any symptoms of anal pain, difficulty in defecation suggesting anal fissure, in order to identify their outcomes, the risk factors for anal fissure development and how they were managed. Results A total of 176 patients were enrolled in this study. Patients were categorized into two groups. The first group included patients who developed anal fissure (n=65) and the 2nd group included patients who did not develop anal fissure (n=111). No significant difference was noted in demographic data apart from the age which was younger in the fissure group. The incidence of anal fissure was 36.9% of total population. The majority of patients' anal fissure problem resolved spontaneously after patients improved from the COVID symptoms without receiving any treatment (43.1%). Conclusion Anal fissure is quite common problem after COVID-19. Young and middle age patients are more vulnerable to develop anal fissure after COVID-19 infection.

The AudibleHealth Dx is a diagnostic software as a medical device (Dx SaMD) consisting of an ensemble of software subroutines that interacts with a proprietary database of Signal Data Signatures (SDS), using Artificial Intelligence/Machine Learning (AI/ML) to analyze forced cough vocalization signal data signatures (FCV-SDS) for diagnostic purposes. This study will evaluate the performance of the AudibleHealth Dx in comparison to a standard of care Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) test for the diagnosis of COVID-19. A secondary purpose of the study will be usability testing of the device for participants and providers.

The purpose of this study is to gain a better understanding of the body's response to a human papillomavirus (HPV) (sexually transmitted disease), vaccine and booster shot. The study will also determine factors related to adolescents not following vaccination schedules. The HPV vaccine requires 3 doses (shots). Girls sometimes receive the 3 shots at the recommended time and sometimes girls receive the shots at non-recommended times. This study will evaluate if getting the shots at non-recommended times affects the level of protection provided by the vaccine. Participants will include about 1400 girls 9-17 years old receiving a third dose of HPV vaccine from their primary care clinician. The parent/legal guardian of each subject may answer a questionnaire related to the vaccine schedule. Study procedures include: medical history, questionnaires and blood draws. Participants will be involved in the study for about 6 months from time of enrollment.

The Study aims to prospectively survey the incidence of respiratory virus infections using molecular methodologies, in children undergoing hematopoietic stem cell transplantation

Chronic viral infections induce oxidative stress that can cause a number of concomitant diseases, e.g. cardio-vascular diseases or metabolic disorders. Therefore, a sufficient treatment of oxidative stress may be of benefit for the patient to prevent further diseases. Shingles (herpes zoster infection) have been successfully treated with antioxidative substances like high-dose vitamin C for ages. Not only the acute symptoms can be diminished by high-dose vitamin C. Even long-term sequelae, like painful post-herpetic neuropathy, may be mitigated or even fully avoided.

The primary objective of this study is to determine the incidence of severe RSV LRTI requiring hospitalization among infants born < 35 weeks gestational age for one year of follow-up.

This study measured the changes in health-related complaints by analyzing charts of individuals, who are infected with a latent virus, who have used Gene-Eden-VIR/Novirin.

The principle purpose of this multicenter trial is to determine the definition, timing and the percentage of nosocomial RSV epidemics throughout Turkey. In addition, secondary purpose of the trial is to determine the prevention strategies of further spread of Respiratory Syncytial Virus (RSV) in the neonatal intensive care unit (NICU).
