Future directions in the evaluation and management of newly diagnosed metastatic cancer.

There is a much debate regarding optimal selection in patients with metastatic cancer who should undergo local treatment (surgery or radiation treatment) to the primary tumor and/or metastases. Additionally, the optimal treatment of newly diagnosed metastatic cancer is largely unclear. Current prognostication systems to best inform these clinical scenarios are limited, as all metastatic patients are grouped together as having Stage IV disease without further incorporation of patient and disease-specific covariates that significantly impact patient outcomes.

Global impact of 10- and 13-valent pneumococcal conjugate vaccines on pneumococcal meningitis in all ages: the PSERENADE project.

Background: Pneumococcal conjugate vaccines (PCVs) introduced in childhood national immunization programs lowered vaccine-type invasive pneumococcal disease (IPD), but replacement with non-vaccine-types persisted throughout the PCV10/13 follow-up period. We assessed PCV10/13 impact on pneumococcal meningitis incidence globally.

Methods: The number of cases with serotyped pneumococci detected in cerebrospinal fluid and population denominators were obtained from surveillance sites globally.

Using Laboratory Test Results for Surveillance During a New Outbreak of Acute Hepatitis in 3-Week- to 5-Year-Old Children in the United Kingdom, the Netherlands, Ireland, and Curaçao: Observational Cohort Study.

Background: In March 2022, a concerning rise in cases of unexplained pediatric hepatitis was reported in multiple countries. Cases were defined as acute hepatitis with serum transaminases >500 U/L (aspartate transaminase [AST] or alanine transaminase [ALT]) in children aged 16 years or younger. We explored a simple federated data analytics method to search for evidence of unreported cases using routinely held data.

ATG8 in single membranes: Fresh players of endocytosis and acidic organelle quality control in cancer, neurodegeneration, and inflammation.

Ubiquitin-like autophagy-related gene ATG8 proteins are typically associated with degradative quality control via canonical double-membrane macro-autophagosomes in the cell. ATG8 proteins have now stepped forward in non-canonical pathways in single membrane organelles. The growing interest in non-canonical ATG8 roles has been stimulated by recent links to human conditions, especially in the regulation of inflammation, neurodegeneration and cancers.

Greenhouse gas emission dynamics and trajectories in urban water supply and wastewater systems.

Urban water utilities are significant energy users and also key actors in decarbonisation. However, the integrated perspective of urban water supply and wastewater system emissions, the relevant driving forces, and the boundaries of inclusions or exclusions, are rarely discussed. This is due to widely disaggregated data, and complex issues regarding the boundary of the system being investigated.

Mercury levels in freshwater aquatic products across China: Spatial distribution, species differences, and health risk assessment.

Freshwater product consumption is a major source of mercury (Hg) exposure in China. This study analyzed Hg concentrations in 12,560 samples from 29 provinces across China (2010-2021) and conducted probabilistic health risk assessments across various life stages. The average Hg concentration in China's freshwater products was 40.

A robust and generalized framework in diabetes classification across heterogeneous environments.

Diabetes mellitus (DM) represents a major global health challenge, affecting a diverse range of demographic populations across all age groups. It has particular implications for women during pregnancy and the postpartum period. The contemporary prevalence of sedentary lifestyle patterns and suboptimal dietary practices has substantially contributed to the escalating incidence of this metabolic disorder.

A retrospective case-control study of pregnancy failure in Thoroughbred horses in Australia.

Pregnancy failure is a serious economic and welfare concern in the Thoroughbred horse industry, yet its incidence and risk factors in Australia remain unclear. This retrospective, nested, case-control study investigated pregnancy failure in resident mares on studs in the Hunter Valley, Australia, in 2021-2022, in early (46-150 days), mid (151-270 days), and late (>270 days) gestation. We found an annual incidence risk of 5.

Female agency and probable depression in the perinatal period and beyond: Longitudinal findings from rural Pakistan.

In Pakistan, a setting with high gender inequality, the relationship between female agency and mental health has not been studied longitudinally or beyond a defined life stage like pregnancy. Using data from the Bachpan cohort of mother-infant dyads in Pakistan, we investigated female agency and depression at two life stages: perinatal (third trimester to 6-months postpartum; n = 1154) and beyond (3- to 4-years postpartum). Modified Poisson models estimated adjusted prevalence ratios (PR) for probable depression (PHQ-9) associated with female agency (freedom of movement and participation in household decision-making) at the two life stages.

Sexual and reproductive health content in Australian pre-registration nursing and midwifery programs: A review of curricula.

Aim: To identify and examine sexual and reproductive health (SRH) content in Australia's pre-registration undergraduate and postgraduate Nursing and Midwifery program curricula.

Background: Sexual and reproductive healthcare, integral to women's well-being, relies on Nursing and Midwifery workforce. However, it is unknown how pre-registration curricula prepares nurses and midwives to provide this care, despite international imperatives to enhance access.

Long-term exposure to fine particulate matter components with obesity in children and adolescents in China: The age-sex disparities and key effect modifiers.

Long-term fine particulate matter (PM) exposure was associated with childhood obesity. However, the key PM components and whether PM effect may vary by obesity type, growth stage, sex, and individual/family characteristics have yet been examined. In this study, we investigated 213,907 Chinese children and adolescents aged 3-18 years in 2017-2019.

Cost-effective production of meaty aroma from porcine cells for hybrid cultivated meat.

Cultivated meats are typically hybrids of animal cells and plant proteins, but their high production costs limit their scalability. This study explores a cost-effective alternative by hypothesizing that controlling the Maillard and lipid thermal degradation reactions in pure cells can create a meaty aroma that could be extracted from minimal cell quantities. Using spontaneously immortalized porcine myoblasts and fibroblasts adapted to suspension culture with a 1 % serum concentration, we developed a method to isolate flavor precursors via freeze-thawing.

Social capital and maternal mental health: Findings from secondary data analyses of two linked longitudinal trials in Australia.

Problem: Low social capital has been identified as an important risk factor in the development of postpartum mental illness.

Background: Evidence suggests that new and expectant mothers with higher levels of support have lower rates of maternal mental illness, yet few studies examine this relationship longitudinally.

Aim: This study investigated the association between social capital in late pregnancy and maternal mental health up to 5 years postpartum.

Exposure to smoking and greenspace are associated with allergy medicine use - A study of wastewaterin 28 cities of China.

Allergies have become an important public health issue as their occurrence is reportedly on the rise around the world. Exposure to environmental factors is considered as trigger for allergic diseases. However, there was limited data on the importance of each factor, particularly in China.

How therapist effects shape pain-related outcome improvement in psychological treatments for chronic pain.

Psychological chronic pain treatments have variable efficacy across individual patients, and on average tend to produce modest effects. In order to improve treatment outcomes, the past decade has seen a rapid increase in research focused on determining the mechanisms underlying treatment-related gains. The near exclusive focus of this research has been on uncovering patient-related mediators and moderators.

Are glucagon-like-peptide-1 (GLP-1) receptor agonists useful in treating Parkinson's disease (PD). Does the clinical trial with lixisenatide add anything?

Introduction: Parkinson's disease (PD) is a common neurodegenerative disease. Glucagon-Like-Peptide-1 (GLP-1) receptor agonists decrease the incidence of developing PD, and are being considered for the treatment of PD.

Areas Covered: A phase 2 clinical trial of lixisenatide, a GLP-1 receptor agonist, in the early stages of PD.

Silica Nanoparticle-Protein Aggregation and Protein Corona Formation Investigated with Scattering Techniques.

Protein-nanoparticle interactions and the resulting corona formation play crucial roles in the behavior and functionality of nanoparticles in biological environments. In this study, we present a comprehensive analysis of protein corona formation with superfolder green fluorescent protein (sfGFP) and bovine serum albumin in silica nanoparticle dispersions using small-angle X-ray scattering (SAXS) and dynamic light scattering (DLS). For the first time, we subtracted the scattering of individual proteins in solution and individual nanoparticles from the protein-nanoparticle complexes.

A phylogenetic approach to delimitate species in a probabilistic way.

Different species concepts and their associated criteria have been used to delimit species boundaries, such as the absence of gene flow for the biological species concept and the presence of morphological distinction for the morphological species concept. The need for different delimitation criteria largely reflects the fact that species are generated under various speciation mechanisms. A key question is how to make species delimitation consistent in a species group, especially when we want to delimit the species boundaries over many newly discovered evolutionary lineages and add these new lineages into a comparative analysis.

Effectiveness and cost-effectiveness of interventions to increase knowledge and awareness of attention deficit hyperactivity disorder: a systematic review.

This review synthesizes evidence on the effectiveness and cost-effectiveness of interventions to increase ADHD awareness and knowledge for caregivers, clinicians, and teachers. Peer-reviewed literature was identified through the systematic searches of six databases: MEDLINE Complete, APA PsycInfo, CINAHL Complete, ERIC, Global Health and EconLit.

The developmental lipidome of Nippostrongylus brasiliensis.

Background: Nippostrongylus brasiliensis-a nematode of rodents-is commonly used as a model to study the immunobiology of parasitic nematodes. It is a member of the Strongylida-a large order of socioeconomically important parasitic nematodes of animals. Lipids are known to play essential roles in nematode biology, influencing cellular membranes, energy storage and/or signalling.

Light and dark biofilm adaptation impacts larval settlement in diverse coral species.

Background: Recovery of degraded coral reefs is reliant upon the recruitment of coral larvae, yet the mechanisms behind coral larval settlement are not well understood, especially for non-acroporid species. Biofilms associated with reef substrates, such as coral rubble or crustose coralline algae, can induce coral larval settlement; however, the specific biochemical cues and the microorganisms that produce them remain largely unknown. Here, we assessed larval settlement responses in five non-acroporid broadcast-spawning coral species in the families Merulinidae, Lobophyllidae and Poritidae to biofilms developed in aquaria for either one or two months under light and dark treatments.

Theory-informed refinement and tailored implementation of a quality improvement program in maternity care to reduce unwarranted clinical variation across a health service network.

Background: Unwarranted clinical variation presents a major challenge in contemporary healthcare, indicating potential inequalities and inefficiencies, and unrealised potential for better outcomes. Despite an increasing focus on unwarranted clinical variation, and consideration of efforts to address this challenge, evidence-based strategies which achieve this are limited. Audit and feedback of healthcare processes (process auditing) and clinician engagement are important tools which may help to reduce unwarranted clinical variation, however their application in maternity care is yet to be thoroughly explored.
