We estimated the seroprevalence of anti-severe acute respiratory syndrome coronavirus 2 (anti-SARS-CoV-2) immunoglobulin G (IgG) in different island groups in Okinawa. A cross-sectional serosurvey was conducted over three periods between July 2020 and February 2021. A total of 2,683 serum samples were collected from six referral medical centers, each covering a separate region in Okinawa. In the main island, the seroprevalence was 0.0% (0/392; 95% confidence interval (CI), 0.0- 0.9%), 0.6% (8/1,448, 0.2-1.1%), and 1.4% (8/582, 0.6-2.7%) during the 1st, 2nd, and 3rd serosurvey, respectively. In remote islands, the seroprevalence was 0.0% (0/144; 95% CI, 0.0-2.5%) and 1.6% (2/123, 0.2-5.8%) during the 2nd and 3rd survey, respectively. The case detection ratio was 2.7 (95% CI, 1.3-5.3) in the main island and 2.8 (0.7-11.1) in remote islands during the 3rd survey. The case detection ratio was the highest in individuals aged 20-29 years (8.3; 95% CI, 3.3-21.4) in the main island and in those aged 50-59 years (14.1; 2.1-92.7) in remote islands, suggesting underreporting of clinical cases by the surveillance system in these subgroups. A serosurvey conducted during an emerging infectious disease epidemic can be useful for validating the reliability of the surveillance system by providing case detection ratio.

Icelandic translation, adaptation and validation of the Parental Burnout Assessment (PBA-IS).
Scand J Occup Ther
January 2025
School of Health, Business and Natural Sciences, University of Akureyri, Akureyri, Iceland.
Background: As parental burnout is increasingly recognised for its severe impact on parents and children, identifying factors that exacerbate or alleviate this condition is crucial. Reliable assessment tools in clinical settings are essential to detect those at risk of or experiencing burnout, enabling timely intervention.
Aims/objectives: This study aims to adapt the Parental Burnout Assessment for use in Iceland and evaluate its psychometric properties while exploring how personal and socio-demographic factors influence parental burnout.
The determinants for death in hospital following moderate to severe traumatic brain injury in Australia.

Objectives: To establish the determinants of death in hospital for patients with moderate to severe traumatic brain injury (TBI) in Australia.
Design, Setting, Participants: Retrospective analysis of Australia New Zealand Trauma Registry (ANZTR) data. Cases were included if they presented to a participating hospital between 1 July 2015 and 30 June 2020 and had an Abbreviated Injury Severity (AIS) score - head greater than 2.
All species must partition resources among the processes that underly growth, survival, and reproduction. The resulting demographic trade-offs constrain the range of viable life-history strategies and are hypothesized to promote local coexistence. Tropical forests pose ideal systems to study demographic trade-offs as they have a high diversity of coexisting tree species whose life-history strategies tend to align along two orthogonal axes of variation: a growth-survival trade-off that separates species with fast growth from species with high survival and a stature-recruitment trade-off that separates species that achieve large stature from species with high recruitment.

Background: Few studies have explored the association between DNA methylation and physical activity. The aim of this study was to evaluate the association of objectively measured hours of sedentary behavior (SB) and moderate physical activity (MPA) with DNA methylation. We further aimed to explore the association between SB or MPA related CpG sites and cardiometabolic traits, gene expression, and genetic variation.

The overall goal of this research was to develop an embryonic stem cell (ESC) line from the Pacific white shrimp, Litopenaeus vannamei, to support production of cell-based cultivated seafood products towards meeting a growing global demand for sustainable seafood. It was hypothesized that characteristics of ESCs, such as high proliferation and pluripotency, would facilitate development of a continuous cell line that could be triggered to differentiate into a muscle cell phenotype. The targeted approach was based on collection of ESCs from fertilized shrimp eggs at the blastomere stage.
