Risk of disruptive behavioural disorders in offspring of mothers with perinatal depressive disorders: A data linkage cohort study.

Background: This study aims to examine the relationship between maternal antenatal and postnatal depressive disorders and the risk of disruptive behavioural disorders (DBDs) in offspring, including conduct disorder (CD) and oppositional defiant disorder (ODD), to enhance understanding and address gaps in the literature.

Methods: We utilised a large administrative health dataset from New South Wales (NSW), Australia. Maternal perinatal depressive disorders and offspring DBDs were identified using International Classification of Diseases (ICD-10) codes.

β-Triketones from Leptospermum scoparium (mānuka) oil show potential as scabicides.

Background: Scabies is a debilitating and neglected infectious disease with limited effective treatment options and affecting millions of people worldwide, mainly in poor and overcrowded settings. Essential oils from Australasian Myrtaceae are known to have parasiticidal properties, often attributed to the presence of β-triketones, which are known inhibitors of the tyrosine catabolism pathway through inhibition of hydroxyphenylpyruvate dioxygenase (HPPD).

Purpose: In this study, essential oils from mānuka (Leptospermum scoparium) were evaluated in vitro for miticidal and ovicidal activities and their active β-triketone constituents (flavesone, leptospermone, and isoleptospermone) were identified.

"Butterflies in the air, you're now a breastfeeding mother": A qualitative study of women's experiences receiving postnatal midwifery breastfeeding support.

Background: Despite breastfeeding being widely accepted as the optimal feeding method for infants many women do not meet their breastfeeding goals or continue to breastfeed as long as recommended. Continuation of exclusive breastfeeding is multifactorial, with midwifery support during the postnatal period considered to be an important component. However, little is known about how women receive this support from midwives across varying models of care.

Systematic Review: Integrated Models of Care for Managing Irritable Bowel Syndrome.

Background: Multidisciplinary integrated models of care show promise for improving symptoms and quality of life (QoL) in adults with irritable bowel syndrome (IBS).

Aims: To describe and evaluate the characteristics of integrated models of care for IBS and identify how digital health is being used in these models of care.

Methods: Four databases were searched to March 2024 for studies that included adults with IBS who participated in multidisciplinary integrated models of care that delivered non-pharmacological therapies.

Examining the Impact of a Brief Compassion Focused Intervention on Everyday Experiences of Compassion in Autistic Adults Through Psychophysiology and Experience Sampling.

Autistic adults experience greater rates of anxiety and depression compared to the general population. Compassion-focused therapy interventions, aimed at promoting self-compassion capabilities, have shown efficacy in improving mental health outcomes in autistic and non-autistic samples suffering from self-criticism that contribute to difficulties in emotion regulation. We explored the experiences of autistic adults during a brief one-week online self-compassion exercise to evaluate it's feasibility and acceptability through self-report, experience sampling, and parasympathetic activity measured via HRV.

Basic Science and Pathogenesis.

Ageing changes the adult brain at the molecular, cellular and functional levels, driving regenerative decline, inflammation, cognitive impairments and susceptibility to dementia-related neurodegenerative disorders, such as Alzheimer's disease (AD). There is overwhelming evidence that regular physical exercise can counteract cognitive decline in both healthy ageing and in neurodegenerative conditions such as AD, with exerkines, the circulating humoral factors that are secreted into the blood stream in response to exercise, emerging as likely mediators of this response. However, the source and identity of these exerkines remain unclear.

Microbial DNA Profiles of Bacterial Extracellular Vesicles from 3D Salivary Polymicrobial Biofilms - A Pilot Study.

With the advent of multi-layered and 3D scaffolds, the understanding of microbiome composition and pathogenic mechanisms within polymicrobial biofilms is continuously evolving. A fundamental component in mediating the microenvironment and bacterial-host communication within the biofilm are bilayered nanoparticles secreted by bacteria, known as bacterial extracellular vesicles (BEVs), which transport key biomolecules including proteins, nucleic acids, and metabolites. Their characteristics and microbiome profiles are yet to be explored in the context of in vitro salivary polymicrobial biofilm.

Increasing the biomolecular relevance of cell culture practice.

The biomolecular relevance of medium supplements is a key challenge affecting cell culture practice. The biomolecular composition of commonly used supplements differs from that of a physiological environment, affecting the validity of conclusions drawn from in vitro studies. This article discusses the advantages and disadvantages of common supplements, including context-dependent considerations for supplement selection to improve biomolecular relevance, especially in nanomedicine and extracellular vesicle research.

Associated factors for parent-reported otitis media in 12-month-old infants.

Objective: To report host-related and environmental factors associated with otitis media (OM), and compare the prevalence of OM in 12-month-old infants reported by parents with that predicted from audiological assessment results.

Design: A non-randomised, cross-sectional design was used. Data were collected via a parental questionnaire during children's audiology appointment at 12 months of age.

Klebsiella pneumoniae species complex bloodstream infection in adult patients: changing epidemiology and determinants of poor outcomes.

Purpose: Klebsiella pneumoniae is a common cause of hospital- and community-acquired infection and can readily acquire multiple antimicrobial resistance determinants leading to poor health outcomes. We define the contemporary burden of disease, risk factors for antimicrobial resistance, and poor health outcomes for patients with K. pneumoniae bloodstream infection (Kp-BSI).

Lysozyme-coated nanoparticles for active uptake and delivery of synthetic RNA and plasmid-encoded genes in plants.

Nanoparticle-mediated delivery of nucleic acids and proteins into intact plants has the potential to modify metabolic pathways and confer desirable traits in crops. Here we show that layered double hydroxide (LDH) nanosheets coated with lysozyme are actively taken up into the root tip, root hairs and lateral root junctions by endocytosis, and translocate via an active membrane trafficking pathway in plants. Lysozyme coating enhanced nanosheet uptake by (1) loosening the plant cell wall and (2) stimulating the expression of endocytosis and other membrane trafficking genes.

OSP-1 protects neurons from autophagic cell death induced by acute oxidative stress.

Oxidative stress, caused by the accumulation of reactive oxygen species (ROS), is a pathological factor in several incurable neurodegenerative conditions as well as in stroke. However, our knowledge of the genetic elements that can be manipulated to protect neurons from oxidative stress-induced cell death is still very limited. Here, using Caenorhabditis elegans as a model system, combined with the optogenetic tool KillerRed to spatially and temporally control ROS generation, we identify a previously uncharacterized gene, oxidative stress protective 1 (osp-1), that protects C.

Essential and dual effects of Notch activity on a natural transdifferentiation event.

Cell identity can be reprogrammed, naturally or experimentally, albeit with low frequency. Why some cells, but not their neighbours, undergo a cell identity conversion remains unclear. We find that Notch signalling plays a key role to promote natural transdifferentiation in C.

Prefrontal dimension change-related activation differs for visual search in sparse and dense displays.

Changes of the target-defining feature dimension have previously been shown to elicit anterior prefrontal activation increases. In the majority of studies, this change-related activation was observed in the left lateral frontopolar cortex. In at least one study, however, right anterior prefrontal activation was observed.

Not "a cute" complication: phenotypic analysis of acute kidney injury in S. aureus bacteraemia.

Objectives: In this large retrospective cohort analysis, we aimed to determine the incidence of KDIGO-defined acute kidney injury (AKI) within 14 days in patients with Staphylococcus aureus bacteraemia, and the association of AKI with 30-day mortality.

Methods: A retrospective cohort study of adults with S. aureus bacteraemia between 1998 to 2023 admitted to a large regional Australian health service.

Diagnostic accuracy of early neonatal MRI in predicting adverse motor outcomes in children born preterm: Systematic review and meta-analysis.

Aim: To examine the diagnostic accuracy of Early structural and diffusion-weighted magnetic resonance imaging (MRI) (acquired at < 36 weeks postmenstrual age) to detect cerebral palsy (CP) or other adverse motor outcomes at or beyond 3 years corrected age in infants born preterm.

Method: In this systematic review and meta-analysis, we searched the CINAHL, Embase, PubMed, and Web of Science databases for studies without language restrictions and a prospectively registered protocol up to October 2023. We extracted the study details, associations presented, and meta-analyses conducted with pooled sensitivity and specificity.

Dosing optimisation of intravenous lidocaine in patients with class 1-3 obesity by population pharmacokinetic analysis.

Introduction: Evidence to support intra-operative lidocaine infusion regimens in patients with obesity is lacking, risking underdosing or toxicity. We aimed to measure the plasma concentrations of lidocaine and its active metabolites to develop a pharmacokinetic model and optimised dosing regimen in patients with obesity.

Methods: A standardised weight-based intravenous lidocaine regimen was administered to patients with a BMI ≥ 30 kg.

A Nurse-Initiated Protocol for Interprofessional Management of Changed Behaviours in Hospital Patients With Dementia and/or Delirium: A Modified e-Delphi Study.

Aim: To develop a nurse-initiated protocol for early ward-based interprofessional coordination and formulation of person-centred care plans to assist in point-of-care management of behaviour in older patients on general hospital wards.

Design: A modified e-Delphi method was employed to establish expert consensus.

Method: Multidisciplinary acute-care experts experienced in hospital care of patients with dementia and/or delirium in Australia were recruited by email from 35 professional networks.

Isolation of a strain from an Eastern Gray Kangaroo.

Methanogenic archaea are a group of microorganisms found in the gastrointestinal tract of various herbivores and humans; however, the quantity (intensity) of methane emissions during feed digestion varies. Macropodids, such as the Eastern Gray Kangaroo (), are considered to be low methane-emitting animals, but their gut methanogenic archaea remain poorly characterized. Characterizing methanogens from animals with low methane emissions offers the potential to develop strategies and interventions that reduce methane emissions from livestock.

Potential influence of different peri-operative analgesic regimens on tumour biology and outcome after oncologic surgery: A narrative review.

The management of peri-operative pain is one of the pillars of anaesthesia and is of particular importance in patients undergoing surgery for solid malignant tumours. Amongst several options, the most commonly employed analgesic regimens involve opioids, NSAIDs and regional anaesthesia techniques with different local anaesthetics. In recent years, several research reports have tried to establish a connection between peri-operative anaesthesia care and outcome after cancer surgery.

The rewards and challenges of self-managing National Disability Insurance Scheme: Exploration of parental perspectives.

Introduction: Under the National Disability Insurance Scheme (NDIS), participants can self-manage their funding. This management style largely deviates from previous Australian service systems. The self-management option provides NDIS participants flexibility and choice in accessing any services; however, it generates an administrative burden.

Dynamics of visual object coding within and across the hemispheres: Objects in the periphery.

The human brain continuously integrates information across its two hemispheres to construct a coherent representation of the perceptual world. Characterizing how visual information is represented in each hemisphere over time is crucial for understanding how hemispheric transfer contributes to perception. Here, we investigated information processing within each hemisphere over time and the degree to which it is distinct or duplicated across hemispheres.

The influence of fetal sex on antenatal maternal glucose and insulin dynamics.

The 'Developmental Origins of Health and Disease' (DOHaD) hypothesis postulates that exposures during critical periods of development and growth, including maternal hyperglycemia, can have significant consequences for short- and long-term health in offspring. The influence of fetal status on maternal (patho)physiology is less well understood but gaining attention. Fetal sex specifically may be an independent risk factor for a range of adverse pregnancy outcomes, including increased gestational diabetes mellitus (GDM) frequency with male fetuses in multi-ethnic populations.
