Evaluation of Three Viral Capsid Integrity qPCR Methods for Wastewater-Based Viral Surveillance.

Capsid Integrity qPCR (CI-qPCR) assays offer a promising alternative to cell culture-based infectivity assays for assessing pathogenic human virus viability in wastewater. This study compared three CI-qPCR methods: two novel (Crosslinker, TruTiter) and one established (PMAxx dye). These methods were evaluated on heat-inactivated and non-heat-inactivated 'live' viruses spiked into phosphate-buffered saline (PBS) and wastewater, as well as on viruses naturally present in wastewater samples.

Objective: To investigate the effect of viral co-infections on treatment length and treatment failure in children with lower respiratory tract infections (LRTI) supported with continuous positive airway pressure (CPAP) or high-flow nasal cannula oxygenation therapy (HFNC).
Methods: Patients aged 0-5 years hospitalized with viral LRTI and in need of respiratory support between August 1 and December 31, 2021, were retrospectively evaluated by patient chart audits.
Results: A total of 148 children (median age 10.
Acute Focal Bacterial Nephritis and Bacteremia Due to Staphylococcus simulans Following an Upper Respiratory Infection in a Child: A Case Report.

Coagulase-negative (CoNS) is a rare cause of UTIs in children and is often regarded as a contaminant in urine samples. We report a case of acute focal bacterial nephritis (AFBN) and bacteremia caused by following an upper respiratory infection in a pediatric patient. The patient, a four-year-old girl, presented with fever, cough, and a runny nose two days before being referred to our hospital due to persistent fever and poor oral intake.

Human adenovirus type 5 (HAdV-5)-based oncolytic viruses hold significant promise for anti-cancer therapy. However, poor tumor-targeting and off-target organ transduction after systemic administration limit their therapeutic efficacy. In addition, the strong liver tropism of HAdV-5-based vectors poses the risk of hepatotoxicity.

Celiac disease (CD) is a chronic autoimmune disease of the small bowel mucosa that develops because of the altered immune response to gluten, which leads to intestinal epithelium damage and villous atrophy. However, studies on regeneration of the damaged small bowel mucosa and density of intestinal stem cells (ISC) in CD persons are still scarce. We aimed to evaluate the number of small bowel mucosa cells positive for LGR5, CD138/Syndecan-1, CD71 and CXCR3 in CD and in controls with normal bowel mucosa; to find relationship between these markers and degree of small intestinal atrophy and to compare these results with our previous data about the number of CD103 + , IDO + DCs, FOXP3 + Tregs, enterovirus (EV) density and serum zonulin level.
