Biotechnological Interventions for the Production of Subunit Vaccines Against Group A Rotavirus.

Group A rotavirus (RVA) is a major cause of severe gastroenteritis in infants and young children globally, despite the availability of live-attenuated vaccines. Challenges such as limited efficacy in low-income regions, safety concerns for immunocompromised individuals, and cold-chain dependency necessitate alternative vaccine strategies. Subunit vaccines, which use specific viral proteins to elicit immunity, provide a safer and more adaptable approach.

The impact of multiplex nested gastrointestinal PCR panel in children with gastroenteridis requiring pediatric infectious disease consultation.

Unlabelled: Infectious gastroenteritis is an important cause of morbidity and mortality, especially in nations with middle and low incomes. In a pediatric gastroenteritis patient, the aim was to determine the therapeutic impact of using the Gastrointestinal Panel in our clinical practice. A single-center retrospective study was designed to evaluate children who were admitted to the hospital for gastroenteritis and had a gastrointestinal panel between August 2021 and January 2024.

Human Metapneumovirus Associated With Acute Hemorrhagic Oedema of Infancy: A Case Report.

Acute Haemorrhagic Oedema of Infancy (AHOI), also known as Acute Hemorrhagic Edema of Infancy (AHEI), is characterized by purpuric skin lesions, edema, and fever. It is classified as a form of cutaneous leukocytoclastic vasculitis. Clinically, AHOI presents with targetoid, purplish spots on the face and limbs, accompanied by the sudden onset of peripheral edema.

Risk of Transmission of Vaccine-Strain Rotavirus in a Neonatal Intensive Care Unit That Routinely Vaccinates.

Background And Objectives: Many neonatal intensive care units (NICUs) do not give rotavirus vaccines to inpatients due to a theoretical risk of horizontal transmission of vaccine strains. We aimed to determine incidence and clinical significance of vaccine-strain transmission to unvaccinated infants in a NICU that routinely administers pentavalent rotavirus vaccine (RV5).

Methods: This prospective cohort study included all patients admitted to a 100-bed NICU for 1 year.

Rotavirus Prevalence in Children with Acute Gastroenteritis Admitted to a Tertiary Hospital in Somalia in 2020-2023: A Retrospective, Single-Center Study.

Purpose: Rotavirus is the leading cause of severe and fatal diarrhea in African children. The aim of this study is to investigate the prevalence of rotavirus in children with acute gastroenteritis admitted to a tertiary hospital in Somalia.

Patients And Methods: 5804 children who applied with complaints of acute gastroenteritis between January 2020 and December 2023 were examined retrospectively.

Caregiver's Knowledge of Childhood Diarrhea Disease Prevention Strategies and Their Associated Factors in Dodoma, Tanzania. A Cross-Sectional Study.

Introduction: Childhood diarrhea remains a leading cause of death in children under 5 years of age worldwide, although the disease is both preventable and treatable. Effective caregiver involvement, rotavirus vaccinations, and parallel diarrhea prevention are critical.

Objectives: This study aimed to assess caregiver's knowledge of childhood diarrheal disease prevention, rotavirus vaccination knowledge, and associated factors in Dodoma, Tanzania.

Rotavirus vaccine effectiveness stratified by national-level characteristics: an introduction to the 24-country MNSSTER-V Project, 2007-2023.

Background: Rotavirus vaccines are moderately protective against illness in high mortality settings compared with low mortality settings. Vaccine effectiveness (VE) evaluations may clarify our understanding of these disparities, but estimates among key subpopulations and against rare outcomes are not available in many analyses due to sample size. We combined 25 datasets from test-negative design case-control evaluations in 24 countries that enrolled children with medically-attended diarrhea, laboratory-confirmed rotavirus stool testing, and documented vaccination status.

The Apparent Lack of the Risk of Intussusception Immediately After Rotavirus Vaccination Among Japanese Infants.

Rotavirus vaccines carry a small risk of intussusception mainly 1-7 days after vaccination in the United States of America, Europe, Australia, and Latin America where the background rate of intussusception is relatively low. Such risks are undetectable in Africa and India where the background rate is the lowest. Because few studies were carried out in high-background-rate countries such as Japan, we examined how intussusception occurred in infants living in Akita prefecture, Japan, while the vaccines were sold in the private market.

Dysregulated Activation of Hippo-YAP1 Signaling Induces Oxidative Stress and Aberrant Development of Intrahepatic Biliary Cells in Biliary Atresia.

The canonical Hippo-YAP1 signaling pathway is crucial for liver development and regeneration, but its role in repair and regeneration of intrahepatic bile duct in biliary atresia (BA) remains largely unknown. YAP1 expression in the liver tissues of patients with BA and Rhesus rotavirus-induced experimental BA mouse models were examined using quantitative reverse transcriptase-PCR and double immunofluorescence. Mouse EpCAM-expressing cell-derived liver organoids were generated and treated with Hippo-YAP1 pathway activators (Xmu-mp-1 and TRULI) or an inhibitor (Peptide17).

spp. Infection in Adult Kidney Transplant Patients: A Systematic Review and Meta-Analysis.

Diarrhea frequently occurs after vascular organ transplantation, including kidney transplants. This may result from non-infectious factors, adverse effects of immunosuppressive medications, or infections caused by various pathogens, including viruses, bacteria, fungi, or parasites, for example, intestinal protozoan parasites such as spp., which are particularly dangerous for immunocompromised patients.

Cost effectiveness analysis of rotavirus vaccination in Indonesia.

Background: Rotavirus (RV) remains the most common cause of morbidity and mortality due to acute gastroenteritis (AGE) in children under five. In Indonesia, RV is responsible for 60 % of severe AGE and 40 % of non-severe AGE in these children. This study assessed the cost-effectiveness of introduction of rotavirus vaccines (RVV) into the National Immunization Program in Indonesia.

Evaluating the Compatibility of Three Aluminum Salt-Adjuvanted Recombinant Protein Antigens (Trivalent NRRV) Combined with a Mock Trivalent Sabin-IPV Vaccine: Analytical and Formulation Challenges.

In this work, we describe compatibility assessments of a recombinant, trivalent non-replicating rotavirus vaccine (t-NRRV) candidate with a mock trivalent Sabin inactivated polio vaccine (t-sIPV). Both t-sIPV and t-NRRV are incompatible with thimerosal (TH), a preservative commonly used in pediatric pentavalent combination vaccines (DTwP-Hib-HepB) distributed in low- and middle-income countries (LMICs), preventing the development of a heptavalent combination. The compatibility of t-NRRV with a mock DTwP-Hib-HepB formulation is described in a companion paper.

Infectious etiology of intussusception in Indian children less than 2 years old: a matched case-control analysis.

Background: Enteric infections are hypothesized to be associated with intussusception in children. A small increase in intussusception following rotavirus vaccination has been seen in some settings. We conducted post-marketing surveillance for intussusception following rotavirus vaccine, Rotavac introduction in India and evaluated association of intussusception with enteric pathogens.

Avian deltacoronaviruses encode fusion-associated small transmembrane proteins that can induce syncytia formation.

Fusion-associated small transmembrane (FAST) proteins are nonstructural viral proteins that induce cell-cell fusion. FAST proteins, which previously were identified in the genomes of double-stranded RNA viruses, typically contain an acylated N-terminal ectodomain, central transmembrane domain, and C-terminal endodomain with a polybasic region. Using sequence homology and protein motif prediction, we identified accessory proteins in a subset of avian deltacoronaviruses as putative FAST proteins.
