Active clinical trials for "Virus Diseases"

To present the first admission chest computed tomography (CT) findings of patients followed up with a diagnosis of COVID-19, and to compare the two classification systems by evaluating these findings according to the BSTI and RSNA guidelines.

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.

In August 2020, West Nile Virus (WNV) was isolated from a live common whitethroat for the first time in The Netherlands. Follow-up sampling showed that the virus could also be detected in mosquitos from the same location during at least a whole month of sampling. On 15 October 2020, one case of West Nile virus infection has been reported in a man who was likely infected in the Utrecht region. This is the first time that a locally acquired human case of WNV infection has been reported in The Netherlands. Six additional cases have been identified, one of which from the region Arnhem. West Nile virus infection is a mosquito-borne zoonosis. The disease, which has spread across the Northern Hemisphere in the past three decades, is now found on an annual basis in many European countries where the centre of gravity lies in Southern-European countries. Recently, WNV was reported for the first time in Germany. The virus is transmitted among birds through the bite of infected mosquitoes and incidentally infects humans and other mammals, such as horses. Around 80% of human WNV infections are asymptomatic. The most common clinical presentation is West Nile fever but, older people and immunocompromised persons are at higher risk of developing neuro-invasive disorders (West Nile neuroinvasive disease). Currently, there are no prophylaxis or specific treatment against the disease in humans. In addition, Usutu virus (USUV) was detected in The Netherlands in 2016. USUV is another flavivirus, related to WNV, and also capable of infecting humans. Disease associated with USUV infection in humans appears to be milder and only limited number of cases have been identified. During their bird catching activities, bird ringers are intensively exposed to mosquito bites at the natural habitat of the birds and at the same time of the day when mosquitoes are particularly active. The aim of this study is therefore to determine the prevalence of WNV and USUV serum antibodies in bird ringers in The Netherlands.

This is a retrospective external field study of a novel in vitro diagnostic (IVD) assay (ImmunoXpert™). The study will involve reviewing the medical charts of about 4500 pediatric patients that were tested using ImmunoXpert™ as part of the routine workup for acute febrile illness. ImmunoXpert™ uses a computer algorithm to combine immunoassay measurements of three host immune proteins (TRAIL, IP-10, and CRP) present in human blood. The test is intended for use in conjunction with clinical assessments and other laboratory findings as an aid to differentiate bacterial from viral infection. Statistical analysis will be performed to compare the diagnostic accuracy of ImmunoXpert™ with that of current practice lab testing e.g., WBC, CRP, and PCT (whichever were taken as part of routine care) and clinical suspicion at time of requisition.

Chronic fatigue syndrome (CFS) is characterized by unexplained, disabling and long lasting fatigue, as well as pain, impaired memory, sleep difficulties and other symptoms. Epstein-Barr virus (EBV) infection might precipitate CFS. In this study, 200 adolescents undergoing acute EBV infection will be followed prospectively, and also compared with a group of healthy controls. The aim is twofold: To identify factors that predispose to chronic fatigue among adolescents with acute EBV infection To compare pathophysiological features of patients with acute EBV infection with a group of healthy controls. Possible risk factors for chronic fatigue 6 months after EBV-infection includes: Severity of the initial infection Immune responses characteristics Characteristics of the neuroendocrine stress response Cognitive functioning Emotional disturbances Genetics/ epigenetics of candidate genes Certain personality traits Critical life events

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 goal of this research is the attempt to implement a new research method based on modern electrochemistry successes, in particular the development of the polarographic method of fructose and fructose diphosphate identification and its implementation to detect the viral infection in early stage. There will be 20 samples from the HIV-infected patients and 30 samples from the heath controls. The study will collect 10ml urine and examined fructose and fructose-diphosphate using the polarographic method.

The study will assess the burden of RSV-attributable general practice consultations, hosptializations, and deaths by age and risk group in in United Kingdom from 1995 to 2009.

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).
