Metabolic dysfunction induced by a high-fat diet modulates hematopoietic stem and myeloid progenitor cells in brown adipose tissue of miceBrown adipose tissue (BAT) may be an important metabolic regulator of whole-body glucose. While important roles have been ascribed to macrophages in regulating metabolic functions in BAT, little is known of the roles of other immune cells subsets, particularly dendritic cells (DCs). Eating a high-fat diet may compromise the development of hematopoietic stem and progenitor cells (HSPCs)-which give rise to DCs-in bone marrow, with less known of its effects in BAT. We have previously demonstrated that ongoing exposure to low-dose ultraviolet radiation (UVR) significantly reduced the 'whitening' effect of eating a high-fat diet upon interscapular (i) BAT of mice.

FcgammaRIIb Expression Is Decreased on Naive and Marginal Zone-Like B Cells From Females With Multiple SclerosisB cells are critical to the development of multiple sclerosis (MS), but the mechanisms by which they contribute to the disease are poorly defined. We hypothesised that the expression of CD32b (FcγRIIb), a receptor for the Fc region of IgG with inhibitory activities in B cells, is lower on B cell subsets from people with clinically isolated syndrome (CIS) or MS. CD32b expression was highest on post-naive IgM+ B cell subsets in healthy controls. For females with MS or CIS, significantly lower CD32b expression was identified on IgM+ B cell subsets, including naive and IgMhi MZ-like B cells, when compared with control females. Lower CD32b expression on these B cell subsets was associated with detectable anti-Epstein Barr Virus viral capsid antigen IgM antibodies, and higher serum levels of B cell activating factor. To investigate the effects of lower CD32b expression, B cells were polyclonally activated in the presence of IgG immune complexes, with or without a CD32b blocking antibody, and the expression of TNF and IL-10 in B cell subsets was assessed.

Facilitators, barriers, and strategies for supporting shared decision-making with people with intellectual disability: A West Australian primary healthcare professional perspectiveShared decision-making between patients and primary healthcare professionals positively impacts health outcomes. However, people with intellectual disability face additional barriers and require supported shared decision-making (SSDM) to participate. Little is known about how healthcare professionals use SSDM with this population. This paper explores the facilitators and barriers experienced, and strategies/resources employed by healthcare professionals working with people with intellectual disability.

Septo-optic dysplasia and gastroschisis: trends in birth prevalence and association with maternal ageThis study aims to describe the risk factors and trends in birth prevalence of septo-optic dysplasia (SOD) and gastroschisis between 1980 and 2023. This descriptive, population-based study of SOD and gastroschisis used Western Australian Register of Developmental Anomalies data from 1980 to 2023. Birth prevalence was calculated using Midwives Notification System data for all births after 20 weeks gestation.

Autism and Attention-Deficit/Hyperactivity Disorder Content in Highly Viewed TikTok VideosSocial media allows users to connect with others’ experiences and points of view, with TikTok being the fastest-growing platform worldwide. Highly viewed videos related to neurodiversity on TikTok have an increasing role in understanding and acceptance of neurodivergent individuals.

Are assisted reproductive technology pregnancies more likely to be exposed to teratogenic medication? A whole-population studyAssisted reproductive technology (ART) pregnancies are at greater risk of birth defects than non-ART pregnancies. Teratogenic medication exposure is a potential cause of birth defects that has not been compared between ART and non-ART pregnancies.

Using Focussed Ethnography to Observe and Understand the Actions and Interactions of People With Prader-Willi Syndrome When They Exercise at a Community Gym: A ProtocolExercise for people with Prader-Willi syndrome (PWS) is important for their health and wellbeing and can provide opportunities for community participation. However, they may find it difficult to participate in some contexts, such as community gyms because social and environmental barriers in these settings may compound difficulties caused by physical impairments or intellectual disability.
