Article Synopsis
  • The study explores how a history of mental disorders, especially PTSD, influences the severity of PTSD symptoms in people affected by earthquakes, highlighting the need for better understanding in treatment.
  • Researchers compared individuals with prior mental disorders to those without and found that those with any past mental issues tend to experience more current psychological disorders.
  • The results indicate that while prior PTSD patients faced more life challenges, the presence of any previous mental disorder doesn't necessarily lead to more severe PTSD, suggesting the importance of screening for all trauma survivors, regardless of their mental health history.

Nonetheless, a detailed understanding of subcellular NADP redox dynamics is limited by the availability of appropriate tools.

There have been frequent reports of more than one strain of the nitrogen-fixing symbiont, Frankia, in the same root nodule of plants in the genus Alnus, but quantitative assessments of their relative contributions have not been made to date. Neither has the diversity of other microbes, having potential functional roles in symbiosis, been systematically evaluated. Alnus rubra root nodule microbiota were studied using Illumina short read sequencing and kmer-based read classification.

Background: During the coronavirus disease 2019 (COVID-19) pandemic, the Australian state of Victoria (in particular, its capital, Melbourne) experienced some of the longest lockdowns in the world.

Objective: This repeated cross-sectional study examined changes between March to June 2019 (pre-pandemic) and April to August 2022 (6 to 11 months following pandemic-related lockdowns) in overweight and obesity prevalence, physical activity, sedentary behaviour, sleep, diet quality, and health-related quality of life (HRQoL) among primary school children in north-east Victoria, Australia.

Methods: Height and weight were measured for Grade 2, 4, and 6 students in 2019 (3889 children) and 2022 (1816 children).
