Similar but Distinct-Biochemical Characterization of the Staphylococcus aureus Serine Hydrolases FphH and FphI.

Staphylococcus aureus is a major cause of infections like bacteremia, pneumonia, and endocarditis. These infections are often linked to the ability of S. aureus to form biofilms.

Cardiovascular-Liver-Metabolic Health: Recommendations in Screening, Diagnosis, and Management of Metabolic Dysfunction-Associated Steatotic Liver Disease in Cardiovascular Disease via Modified Delphi Approach.

There is a new awareness of the widespread nature of metabolic dysfunction-associated steatotic liver disease (MASLD) and its connection to cardiovascular disease (CVD). This has catalyzed collaboration between cardiologists, hepatologists, endocrinologists, and the wider multidisciplinary team to address the need for earlier identification of those with MASLD who are at increased risk for CVD. The overlap in the pathophysiologic processes and parallel prevalence of CVD, metabolic syndrome, and MASLD highlight the multisystem consequences of poor cardiovascular-liver-metabolic health.

Impact of the Stigma of Mental Illness: A Descriptive Exploratory Study of Outpatients in a Public Mental Health Hospital in Ghana.

Despite ongoing efforts, persons with mental illness (PWMI) continue to experience stigma and discrimination and with profound negative outcomes. This study examined the psychological and social impact of the stigma attached to mental illness as experienced by out-patients at a public mental health facility. We applied a descriptive exploratory method using a semi-structured interview guide to elicit subjective responses from 12 Outpatient Department members.

Executive functioning challenges of adolescents born extremely and very preterm.

Background: Children born very preterm (VPT; <32 weeks) are at increased risk of executive functioning (EF) difficulties. But less is known about the nature and extent of these executive difficulties during late adolescence, particularly across multiple EF domains and in response to varying degrees of executive demand.

Methods: Using data from a prospective longitudinal study, this paper describes the EF profiles of 92 VPT and 68 full-term (FT) adolescents at age 17 years.

Effect of Moderate Red Meat Intake Compared With Plant-Based Meat Alternative on Psychological Well-Being: A 10-Wk Cluster Randomized Intervention in Healthy Young Adults.

Background: A healthy diet has been proposed to support good mental health, but the addition of either red meat or meat alternatives is nuanced.

Objectives: We aimed to determine if psychological and physiological well-being is differentially affected by consuming recommended weekly amounts of either lean red meat or plant-based meat alternatives (PBMAs) supplemented with a plant-rich diet.

Methods: The trial was a parallel 2-arm randomized intervention of 10 wk duration.

Alteration of host gene and protein expression by manipulative parasites.

Host manipulation mechanisms remain poorly understood. We summarize recent studies using -omics approaches (transcriptomics, proteomics) to explore alteration in gene expression in hosts infected by manipulative parasites. To guide future research, we highlight the common pattern of neuromodulation, as well as other diverse combinations of functions targeted across different host manipulation systems.

3D-printed suction clamps for tensile testing of brain tissue.

The conventional mounting of ultra-soft biological tissues often involves gluing it between two plates or manually tightening grips. Both methods demand delicate handling skills and are time-consuming. This study outlines the design and practical application of 3D-printed suction clamps for uniaxial tension tests on brain samples.

Impact of Australia's No Jab, No Pay policy on vaccination uptake - a before-after study in two national birth cohorts.

Background: Data on impact of financial penalties for non-vaccination are sparse. Australia has required full vaccination for government family assistance payment eligibility since 1998. In 2016, the No Jab, No Pay (NJNP) policy removed registered non-medical objection as exemption option and increased eligibility assessment to yearly.

Consent to medical student teaching: an observational, cross-sectional study exploring the patient view.

Background: New Zealand guidelines stipulate that patient consent is obtained for medical student involvement in clinical care, however, patients' preferences regarding consent for medical student teaching have not been widely explored. This study examined patient preferences for consent for medical student teaching with the aim to increase patient empowerment, to optimise care and to reflect societal expectations more accurately.

Method: Observational, semi-qualitative, cross-sectional study of in-patients.

Development of evidence-based standards for inpatient physiotherapy services: a systematic review and content analysis of clinical practice guidelines.

Objective: Performance standards are critical to service design and quality improvement. There are no published standards defining the care inpatients should receive from physiotherapists in Aotearoa New Zealand. This study aims to explore the potential of using clinical practice guidelines (CPGs) to develop a set of evidence-based standards for physiotherapy in inpatient settings.

Identification of plasma protein biomarkers for endometriosis and the development of statistical models for disease diagnosis.

Study Question: Can a panel of plasma protein biomarkers be identified to accurately and specifically diagnose endometriosis?

Summary Answer: A novel panel of 10 plasma protein biomarkers was identified and validated, demonstrating strong predictive accuracy for the diagnosis of endometriosis.

What Is Known Already: Endometriosis poses intricate medical challenges for affected individuals and their physicians, yet diagnosis currently takes an average of 7 years and normally requires invasive laparoscopy. Consequently, the need for a simple, accurate non-invasive diagnostic tool is paramount.

Characteristics and management of eosinophilic esophagitis in Australasian children: a decade of experience.

Background: The frequency of EoE has been increasing in Northern Hemisphere cohorts, yet there is a scarcity of data in our region. Regional climatic factors, and lifestyle habits may influence the presentation of EoE, and appropriate management is crucial to prevent complications. WIth this is mind we undertook the first comprehensive multisite study of EoE in Australasian children.

The periodicity of enamel laminations in human deciduous molars.

Objective: Enamel laminations are closely spaced incremental lines that run parallel to Retzius lines or the developing enamel surface. Here, the timing of enamel laminations is calculated for naturally exfoliated deciduous molars (n = 111) from three modern-day populations (Aotearoa New Zealand, Britain and Canada).

Design: Teeth were sectioned using standard histological methods and examined using a high-powered microscope.

Unique bibenzyl cannabinoids in the liverwort Radula marginata: parallels with Cannabis chemistry.

The potential of cannabinoids to address public health challenges has stimulated exploration into alternative sources and production technologies. Radula marginata, an endemic Aotearoa/New Zealand liverwort, produces the bibenzyl cannabinoid perrottetinene (PET), analogous to Cannabis psychoactive tetrahydrocannabinol (THC). Structural differences between PET and THC could alter therapeutic interactions and mitigate adverse side effects.

Loneliness in older persons with schizophrenia.

Background: In tandem with the rise in numbers of older adults in the general population, more people with schizophrenia (PwS) are also living longer. This vulnerable population has several trajectories of ageing driven by a number of social determinants of health, including the experience of loneliness and they may be more at risk of experiencing loneliness.

Aim: This study aimed to examine demographic, psychosocial and clinical variables and their relative contribution to the loneliness of older PwS (OPwS) in a large New Zealand community sample.

Covalent-fragment screening identifies selective inhibitors of multiple Staphylococcus aureus serine hydrolases important for growth and biofilm formation.

is a leading cause of bacteria-associated mortality worldwide. This is largely because infection sites are often difficult to localize and the bacteria forms biofilms which are not effectively cleared using classical antibiotics. Therefore, there is a need for new tools to both image and treat infections.

Objective: The aim of this research was to determine how common gout flares are after ceasing anti-inflammatory prophylaxis.

Methods: A rapid literature review and meta-analysis were undertaken. PubMed was searched from inception to February 2024.

The climate emergency for rheumatologists: where do we stand?

Climate change and pollution are a major existential threat. Healthcare contributes a noteworthy 4-6% to the total carbon footprint and 5-7% of the total greenhouse gas (GHG) emissions. Environmental pollution and modern lifestyles are also contributing to the increased prevalence of autoimmune and lifestyle-related rheumatic disease.

Mass spectrometric detection of neutrophil elastase cleaved corticosteroid binding globulin and its association with Asn347 site glycosylation, in septic shock patients.

Background: Corticosteroid-binding globulin (CBG) modulates tissue cortisol availability via modification of cortisol:CBG binding affinity in response to multiple factors, including neutrophil elastase (NE) cleavage of the reactive centre loop (RCL), converting high affinity CBG (haCBG) to low affinity CBG (laCBG). In vitro, glycosylation of the RCL at Asn347 affects NE cleavage susceptibility. To date, no direct measurement of laCBG, which would verify NE cleavage, has been reported.

Effectiveness of the primary Bacillus Calmette-Guérin vaccine against the risk of Mycobacterium tuberculosis infection and tuberculosis disease: a meta-analysis of individual participant data.

Background: Tuberculosis vaccine trials using disease as the primary endpoint are large, time consuming, and expensive. An earlier immunological measure of the protection against disease would accelerate tuberculosis vaccine development. We aimed to assess whether the effectiveness of the Bacillus Calmette-Guérin (BCG) vaccine for prevention of Mycobacterium tuberculosis infection was consistent with that for prevention of tuberculosis disease.

The importance of microbiology reference laboratories and adequate funding for infectious disease surveillance.
