This is the first study that investigated the presence, distribution, and composition of microplastics, MPs (1-5 mm) on beaches in the Yasawa Islands, Fiji. A temporal assessment over three years on six beaches was undertaken to investigate different beach traits on MP abundance. Average MP concentration was 4.5 ± 11.1 MPs·m with significantly higher concentrations were found on east-facing beaches than west (p < 0.001), and higher on the storm line compared to the high tide line (p < 0.001). No difference was found between tourist and local beaches (p = 0.21). These results demonstrate the role of current-driven ocean transport of plastic pollution in this part of The South Pacific. ATR FT-IR analysis showed that across all sites 34 % of MPs were polypropylene (PP), 33 % polystyrene (PS), 25 % polyethylene (PE), and 8 % other polymer types. Further studies are needed to assess the potential impacts of MPs on Fiji's coral reefs and marine life.

Mapping the myomagnetic field of a straight and easily accessible muscle after electrical stimulation using triaxial optically pumped magnetometers (OPMs) to assess potential benefits for magnetomyography (MMG). Approach: Six triaxial OPMs were arranged in two rows with three sensors each along the abductor digiti minimi (ADM) muscle. The upper row of sensors was inclined by 45° with respect to the lower row and all sensors were aligned closely to the skin surface without direct contact.

The incidence of thyroid cancer has shown marked increases globally over recent decades. This study investigated how the incidence of papillary thyroid carcinoma (PTC) subtypes and World Health Organisation (WHO) endocrine tumour classification changes have affected overall thyroid cancer incidence recorded in Australia. Using incidence data from the Australian Institute of Health and Welfare cancer registry (spanning 1982 to 2019), this descriptive epidemiological study employed joinpoint regression analysis to assess temporal trends in thyroid carcinoma incidence, focusing on PTC.

Introduction: Active duty service members (ADSMs) may be at heightened risk for eating disorders (EDs) and sub-clinical disordered eating (DE). ADSMs are also at a high risk for musculoskeletal injury (MSK-I). Given the risk for EDs/DE among ADSMs as well as robust physical requirements of military training, additional research is needed to elucidate links between DE and risk for MSK-I among ADSMs.

Background: Helicobacter pylori (H. pylori) has been inconsistently associated with risk of Alzheimer disease. The exposure assessment period has often overlapped with the prodromal time of Alzheimer disease.
View Article and Find Full Text PDFPsychotic disorders, such as schizophrenia and bipolar disorder, pose significant diagnostic challenges with major implications on mental health. The measures of resting-state fMRI spatiotemporal complexity offer a powerful tool for identifying irregularities in brain activity. To capture global brain connectivity, we employed information-theoretic metrics, overcoming the limitations of pairwise correlation analysis approaches.
