Prevalence and characteristics of adults with preserved ratio impaired spirometry (PRISm): Data from the BOLD Australia study.

Individuals with Preserved Ratio Impaired Spirometry (PRISm), defined as FEV/FVC ≥0.7 and FEV1 <80% predicted, are at higher risk of developing COPD. However, data for Australian adults are limited.

Conducting Pairwise and Network Meta-analyses in Updated and Living Systematic Reviews: a Scoping Review Protocol.

Objective: The objective of this scoping review will be to describe existing guidance documents or studies reporting on the conduct of meta-analyses in updated systematic reviews (USRs) or living systematic reviews (LSRs).

Introduction: The rapid increase in the medical literature poses a substantial challenge in keeping systematic reviews up to date. In LSRs, a review is updated with a pre-specified frequency or when some other signalling criterion is triggered.

Global Delphi consensus on treatment goals for generalised pustular psoriasis.

Background: Generalised pustular psoriasis (GPP) is a chronic, systemic, neutrophilic inflammatory disease. A previous Delphi panel established areas of consensus on GPP, although patient perspectives were not included, and aspects of treatment goals remain unclear.

Objectives: To identify and achieve consensus on refined, specific treatment goals for GPP treatment via a Delphi panel with patient participation.

Interrupted time series datasets from studies investigating the impact of interventions or exposures in public health and social science: a data note.

Objectives: The interrupted time series (ITS) design is commonly used to investigate the impact of an intervention or exposure in public health. There are many statistical methods that can be used to analyse ITS data and to meta-analyse their results. We undertook two empirical studies to investigate: (i) how effect estimates (and associated statistics) compared when six statistical methods were applied to 190 real-world datasets; and (ii) how meta-analysis effect estimates (and associated statistics) compared when the combinations of two ITS analysis methods and five meta-analysis methods were applied to 17 real-world meta-analyses including 283 ITS datasets.

Socioeconomic inequality in hypertension and its determinants in people over 60 years in Fasa, southern Iran: a Blinder-Oaxaca decomposition.

Background: Hypertension (HTN) is well-known as a major risk factor for various noncommunicable diseases. Evidence indicates a link between socioeconomic status and the likelihood of developing HTN. A thorough comprehension of the inequalities in HTN is crucial for implementing evidence-based interventions.

A dataset of Antarctic ecosystems in ice-free lands: classification, descriptions, and maps.

Antarctica, Earth's least understood and most remote continent, is threatened by human disturbances and climate-related changes, underscoring the imperative for biodiversity inventories to inform conservation. Antarctic ecosystems support unique species and genetic diversity, deliver essential ecosystem services and contribute to planetary stability. We present Antarctica's first comprehensive ecosystem classification and map of ice-free lands, which host most of the continent's biodiversity.

The Contribution of Adverse Childhood Experiences and Neighborhood Characteristics on Outcomes Experienced by Urban Dwelling Black Men After Serious Traumatic Injury.

Depression and post-traumatic stress disorder (PTSD) are serious consequences of physical injuries. Stress associated with living in urban neighborhoods with socioecological disadvantages and the cumulative burdens of adverse childhood experiences (ACEs) can lead to poorer psychological outcomes. Limited research has explored how ACEs and socioecological environmental exposures in childhood and adulthood, together, impact post-injury outcomes.

Genomics yields biological and phenotypic insights into bipolar disorder.

Bipolar disorder is a leading contributor to the global burden of disease. Despite high heritability (60-80%), the majority of the underlying genetic determinants remain unknown. We analysed data from participants of European, East Asian, African American and Latino ancestries (n = 158,036 cases with bipolar disorder, 2.

Examining the role of Acinetobacter baumannii plasmid types in disseminating antimicrobial resistance.

Acinetobacter baumannii is a Gram-negative pathogen responsible for hospital-acquired infections with high levels of antimicrobial resistance (AMR). The spread of multidrug-resistant A. baumannii strains has become a global concern.

Your period and your pregnancy, a cohort study of pregnant patients investigating the associations between menstruation and birth outcomes in Australia: study protocol.

Introduction: Early pregnancy care involves the screening and identification of women with risk factors for adverse pregnancy outcomes, including stillbirth or preterm birth, to tailor pregnancy care and interventions accordingly. Most stillbirths and approximately two-thirds of preterm births, however, occur in the absence of evident risk factors. The majority of stillbirths occur in the preterm period, yet there are few interventions targeting this period, and progress to reduce stillbirth rates remains slow.

"Basically, my answer is, there needs to be options!" Recommendations for the delivery of free menstrual products to the public: A qualitative exploration among marginalised groups in Victoria, Australia.

Objective: Governments have announced free menstrual product provision policies. Our research aimed to inform these initiatives by understanding menstrual product insecurity amongst marginalised groups and their recommendations for product provision.

Methods: We undertook in-depth interviews with participants experiencing menstrual product insecurity, who identified as belonging to one or more marginalised groups, alongside key informants working for organisations serving these populations.

Airway clearance techniques for people with acute exacerbation of COPD: a scoping review.

Introduction: Acute exacerbations of COPD (AECOPD) often involve mucus hypersecretion. Thus, management of sputum retention is critical. However, the use of airway clearance techniques (ACTs) in people with AECOPD across different healthcare settings and factors influencing their selection remain unclear.

Enhanced analysis of cellulose nanofibril film structure.

Structural analysis of cellulose nanofibril (CNF) films remains challenging due to the stochastic assembly of fibres and presence of nanopores. This limits our ability to link the film structures to their properties, restricting their commercial use. While X-ray micro-computed tomography (μCT) is a powerful technique to map the structure of traditional and commercial paper, there has been limited success in its application for CNF films due to the poor contrast between pores and material, making the reconstructed images difficult to segment and analyse.

Mechanisms of the TGF-β1/Smad3-signaling pathway in gender differences in alcoholic liver fibrosis.

The TGF-β1/Smad3-signaling pathway and gender differences were investigated in alcoholic liver fibrosis. Mice were divided into female normal, female model, male normal, and male model groups. Liver injury and fibrosis were assessed using histopathology and serology.

Machine-learning versus traditional methods for prediction of all-cause mortality after transcatheter aortic valve implantation: a systematic review and meta-analysis.

Background: Accurate mortality prediction following transcatheter aortic valve implantation (TAVI) is essential for mitigating risk, shared decision-making and periprocedural planning. Surgical risk models have demonstrated modest discriminative value for patients undergoing TAVI and are typically poorly calibrated, with incremental improvements seen in TAVI-specific models. Machine learning (ML) models offer an alternative risk stratification that may offer improved predictive accuracy.

Which variables are associated with recruitment failure? A nationwide review on obstetrical and gynaecological multicentre RCTs (2003-2023).

Objective: We aim to assess which variables are associated with recruitment failure of obstetrical and gynaecological randomised controlled trials (RCTs), leading to an extension of the study period.

Design: Nationwide study.

Setting: A cohort of RCTs supported by the trial centre of the Dutch Consortium of Obstetrics and Gynaecology.

Engineered antigen-specific T regulatory cells suppress autoreactivity to the anti-glomerular basement membrane disease antigen.

Anti-glomerular basement membrane (anti-GBM) disease is accompanied by insufficient antigen-specific T regulatory cells (Tregs) and clonally expanded antigen-specific T conventional cells (Tconvs). In particular, this applied to the immunodominant T cell auto- epitope of type IV collagen, α3(IV)NC1135-145 , presented by HLA-DR15. Here, we investigated whether Tregs engineered to express GBM-T cell receptors (TCR) specific for α3(IV)NC1135- 145 better suppress autoimmunity.

A post-injury immune challenge with lipopolysaccharide following adult traumatic brain injury alters neuroinflammation and the gut microbiome acutely, but has little effect on chronic outcomes.

Patients with a traumatic brain injury (TBI) are susceptible to hospital-acquired infections, presenting a significant challenge to an already-compromised immune system. The consequences and mechanisms by which this dual insult worsens outcomes are poorly understood. This study aimed to explore how a systemic immune stimulus (lipopolysaccharide, LPS) influences outcomes following experimental TBI in young adult mice.

Nanoscale interaction mechanism between bubbles and microplastics under the influence of natural organic matter in simulated marine environment.

Bubble-microplastic (MP) interaction is a significant process that changes the routes of MP circulation in marine environment and thereby determines the risk of MPs, which could be strongly influenced by natural organic matter (NOM) in oceans. However, the quantitative interaction mechanisms between bubbles and MPs under the effect of NOM remain elusive. Herein, bubble-MP interactions in simulated seawater were quantified at nanoscale based on atomic force microscope coupled with the Stokes-Reynold-Young-Laplace model.

Respiratory symptoms after coalmine fire and pandemic: A longitudinal analysis of the Hazelwood Health Study adult cohort.

The aim of this study was to determine whether the effects of extreme but discrete PM2.5 exposure from a coal mine fire on respiratory symptoms abated, persisted, or worsened over time, and whether they were exacerbated by COVID-19. We analysed longitudinal survey data from a cohort residing near a 2014 coalmine fire in regional Australia.

Non-dominant hand contractions do not facilitate performance under pressure in common desktop tasks.

Non-dominant hand contractions (NDHCs) have been shown to help expert motor skills in high-pressure scenarios that induce performance anxiety. Most studies of NHDCs under pressure have examined benefits in overlearned specialist movements (e.g.

Physical activity alleviated associations of oxidation capacity of the atmosphere with platelet-based inflammatory indicators: findings from the Henan Rural Cohort Study.

: several adverse effects of ozone (O) and nitrogen dioxide (NO) are assessed using combined oxidant capacity (O) and redox-weighted oxidant capacity (Owtx) as surrogates. However, the associations of oxidant capacity (O and Owtx) with platelet-based inflammatory indicators and the potential modifying role of physical activity (PA) remain unclear. : 31 318 participants were selected from the baseline survey of the Henan Rural Cohort Study.
