AI Article Synopsis
- A four-year seroprevalence study for toxoplasmosis infection was conducted on Seokmo-do Island, Korea, using a rapid diagnostic test on serum samples collected yearly from residents.
- The overall positive seroprevalence increased from 29.2% in 2010 to 45.3% in 2013, with a notable gender disparity showing higher rates in males compared to females.
- The unique environment of the relatively isolated island, along with its connectivity to the mainland, may have influenced the increased rates, suggesting a need for further research on symptomatic cases and risk factors.
Article Abstract
Seroprevalence of infection among the residents of Seokmo-do (Island) in Ganghwa-gun, Incheon, Korea was surveyed for 4 years by a rapid diagnostic test (RDT) using recombinant fragment of major surface antigen (SAG1), GST-linker-SAG1A. Sera from 312, 343, 390, and 362 adult residents were collected on a yearly basis from 2010 to 2013, respectively. Total positive seroprevalence regardless of gender was 29.2, 35.3, 38.7, and 45.3% from 2010 to 2013, respectively. Positive seroprevalence in male adults was 43.9, 48.2, 45.4, and 55.3%, which was far higher than that of the corresponding female adults which was 20.7, 29.2, 33.9, and 38.9%, from 2010 to 2013, respectively. This high seroprevalence of toxoplasmosis in Seokmo-do may have been caused in part by peculiar changes in the toxoplasmic environment of the island as it is a relatively isolated area preserving its natural habitat while also being connected by a bridge to the mainland. Further study is necessary to find out symptomatic patients and to confirm the risk factors.

Identifying biomarker-driven subphenotypes of cardiogenic shock: analysis of prospective cohorts and randomized controlled trials.

Background: Cardiogenic shock (CS) is a heterogeneous clinical syndrome, making it challenging to predict patient trajectory and response to treatment. This study aims to identify biological/molecular CS subphenotypes, evaluate their association with outcome, and explore their impact on heterogeneity of treatment effect (ShockCO-OP, NCT06376318).
Methods: We used unsupervised clustering to integrate plasma biomarker data from two prospective cohorts of CS patients: CardShock (N = 205 [2010-2012, NCT01374867]) and the French and European Outcome reGistry in Intensive Care Units (FROG-ICU) (N = 228 [2011-2013, NCT01367093]) to determine the optimal number of classes.

Importance: Aging is accompanied by immune dysregulation, which has been implicated in Alzheimer's disease (AD) pathogenesis. Individuals who are genetically predisposed to elevated levels of proinflammatory mediators might be at increased risk for AD.
Objective: To investigate whether genetic propensity for higher circulating levels of interleukin 6 (IL-6) is associated with AD risk.

Background: Podocyte depletion is a critical factor in glomerulosclerosis development. While podocyte numbers per glomerulus typically decline with age in adults, they are hypothesized to increase during childhood. However, studies on podocyte number progression in childhood have been limited.
