Revealing trends in measles immunity during periods of varying measles circulation in Madagascar.

Estimating the durability of immunity from vaccination is complicated by unreported re-vaccination, and unobserved natural infection or reexposure, which could result in overestimation of protection longevity. We tested serial cross-sectional serum samples from 2005 to 2015 (N=2,530) for IgG to examine measles seroprevalence, spatiotemporal patterns of titers across regions and antibody dynamics among children aged 1-9 years who grew up during varying measles circulation in Madagascar under a one-dose vaccination schedule. We found that measles seroprevalence has generally decreased over this time period.

The detection of Japanese encephalitis virus (JEV) in pigs, at four piggeries in the Murray region in February 2022, prompted a public health investigation (PHI) by the New South Wales Department of Health (NSW Health) to identify people at greatest risk of infection. The PHI included three components: a vaccination clinic and accompanying clinic questionnaire; a serological investigation; and a cross-sectional study for consenting Australian-born participants who completed an extended questionnaire after receiving their serological results. The goals were to vaccinate a presumably naïve population to reduce associated risk and to understand the seroprevalence among Australian-born piggery workers.

Department of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiao Tong University School of Medicine Shanghai Institute of Digestive Diseases, Shanghai 200127, China.
Background: The relationship between autoimmune gastritis (AIG) and gastric polyps (GPs) is not well understood.
Aim: To explore the clinical characteristics and risk factors of AIG with GPs in patients.
Methods: This double center retrospective study included 530 patients diagnosed with AIG from July 2019 to July 2023.
Risk factors and preventive role of vaccination in adult tetanus fatality: a systematic review of reported cases (1990-2024) and meta-analysis.

Objectives: This study identifies key risk factors for fatality among adult tetanus patients and assesses the impact of vaccination status and antibody levels on disease severity and outcomes in tetanus cases. Despite widespread vaccination, fatality rates remain high due to diagnostic and management challenges.
Design/methods: A meta-analysis of 182 tetanus cases from 36 countries, published since 1990, was conducted.
The protective effect of serum antibodies in preventing SARS-CoV-2 virus entry into cardiac muscle.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been associated with significant cardiovascular complications, including myocardial infection and pulmonary embolism. This study aims to elucidate the relationship between the presence of SARS-CoV-2 RNA in the myocardium of the left ventricle and the levels of IgG and IgM antibodies against the SARS-CoV-2 virus in deceased COVID-19 patients. We conducted a post-mortem examination on 91 individuals who succumbed to COVID-19-related complications.
