Hepatitis B Vaccination After Neonatal Surgery
At present, whether the hepatitis B vaccine (HBV) can be vaccinated on time after neonatal surgery has become a common problem for children's families, neonatal surgeons, and vaccination departments, but there are few relevant studies at home and abroad, and there is no corresponding guide or consensus. In the early …
Understanding Immunity to the Flu Vaccine in COVID-19 Patients
The purpose of this study is to measure immunity to the flu vaccine over time in patients who have had COVID-19 and may have other medical conditions including obesity, type 2 diabetes, chronic fatigue, or long-term COVID-19 symptoms. Adults and children (age 13 to 64) who had been diagnosed with …
Torque Teno Virus: A Biomarker of Immunosuppression
To seek an association between Torque Teno Virus DNA titres resulting from under or over-immunosuppression in a kidney allograft recipient, Graft rejection, both cell-mediated rejection and antibody-mediated rejection, donor-specific antibodies (DSA), the incidence of BK viraemia and BK nephropathy, CMV infection or diseases and PCP infection and the number of …
Pharmacokinetics of Intravenous Acyclovir in Oncologic Paediatric Patients
Herpesvirus infections may be severe in immunocompromised patients, with a high risk of complications and mortality. Recipients of hematopoietic stem cell transplant (HSCT) or patients receiving high-intensity chemotherapy for hematological malignancies are the most vulnerable individuals. Although the worldwide prevalence of herpes simplex virus 1 (HSV-1) and varicella-zoster virus (VZV), …
Observational Digital Biomarker Discovery in Respiratory Virus Challenge Studies
Background Respiratory viruses circulate throughout the year and around the globe. Wearable and sensor devices, like smartwatches, may be able to help monitor infectious diseases. Researchers want to use them to learn how respiratory viruses affect people in different ways. Objective To use digital devices to collect data from participants …
Impact of Hepatitis B Virus on Inflammatory Bowel Disease
The goal of this observational retrospective study is to assess the impact of hepatitis B virus (HBV) infection on the clinical course and outcomes of inflammatory bowel disease (IBD) in Egyptian patients. Researchers will compare the IBD extent, location, severity, and behavior between IBD patients with and without HBV infection. …
OBSERVATIONAL STUDY ON VIRAL SHEDDING AND IMMUNOLOGICAL RESPONSE OF OROPOUCHE VIRUS
This is a single-center observational study, whose primary objective is to describe the immune response to Oropouche Virus (OROV) during the study period and the duration of viral RNA shedding, only for sequential samples, by RT-PCR in different matrices.
Sequencing-based Counting of Plasma Epstein-Barr Virus DNA in Non-metastatic Nasopharyngeal Carcinoma
The investigators aim to explore a new EBV DNA surveillance method with both high sensitivity and specificity in nasopharyngeal carcinoma (NPC) patients. the investigators aim to conduct plasma EBV DNA counting by next generation sequencing (NGS) in non-metastatic NPC patients on their diagnose, after two cycles of induction chemotherapy (IC), …
Monitoring of Chronic Conditions in Breast Cancer
REBECCA-1 is an observational study. Clinical research is undergoing a revolutionary change. The use of electronic patient records (EHR), digital registers, smartphones etc will create "real-world data" (RWD) that provides great opportunities for advancing clinical research, but so far this opportunity has been little exploited. The REBECCA -1 study will …
Impact of Hepatitis B Virus Genotype on Treatment Response in Children With Chronic Hepatitis B
The study aimed to evaluate the relationship between hepatitis B virus genotype and treatment response in children with chronic hepatitis B with specific treatment indications. This is a prospective cohort study, with a follow-up period of at least 12 months, conducted at Children's Hospital 1 and City Children's Hospital, Ho …
