Antibody responses against influenza A decline with successive years of annual influenza vaccination.

Influenza vaccine effectiveness and immunogenicity can be compromised with repeated vaccination. We assessed immunological markers in a cohort of healthcare workers (HCW) from six public hospitals around Australia during 2020-2021. Sera were collected pre-vaccination and ~14 and ~180 days post-vaccination and assessed in haemagglutination inhibition assay against egg-grown vaccine and equivalent cell-grown viruses.

Measurement tools used to assess individual health assets among refugee populations: a scoping review.

Forced migration is increasing globally, which has detrimental effects on the physical and mental health of refugees, who may face significant challenges accessing healthcare services. However, refugees also possess considerable strengths or assets that can protect against various health challenges. Identifying and strengthening the individual health assets of refugees is critical to promoting their health and mitigating these health challenges.

Nutrition literacy in Vietnamese pregnant women: a cross-sectional study.

Inadequate nutrition intake during pregnancy elevates the risk of adverse health outcomes during pregnancy, with potential long-term repercussions for both mother and child, extending to subsequent generations. Current initiatives to improve individual dietary habits emphasize promoting nutrition literacy (NL), which encompasses the ability to access, comprehend, and use basic nutrition information and services necessary for making appropriate nutrition decisions. However, there were limited data on the NL of pregnant women in Vietnam.

Patient safety is our business! Staff perspectives on implementing hospital falls prevention education.

Providing patients with falls prevention education reduces falls in hospitals, yet there is limited research on what influences successful implementation at the staff, ward and hospital levels. We engaged hospital-based health professionals to identify multi-level barriers and enablers to patient falls education that could influence the implementation of a Safe Recovery program. Purposive sampling was used to recruit hospital staff (n = 40) for focus groups and one-on-one interviews.

Phase I study of CD19 CAR T-cell therapy harboring a fully human scFv in CAR-naïve adult B-ALL patients.

CD19-directed chimeric antigen receptor-engineered (CD19 CAR) T-cell therapy elicits high response rates but fails to induce durable responses in most adults with relapsed or refractory (R/R) B-cell acute lymphoblastic leukemia (B-ALL). In a previous clinical trial (NCT01865617), we observed anti-CAR immune responses associated with impaired in vivo CAR T-cell expansion after second infusions. Because these CD8+ T-cell responses were predominantly directed at peptides derived from the murine single chain variable fragment (scFv) in the CAR, we conducted a clinical trial investigating the safety and efficacy of CD19 CAR T-cells engineered with a CAR incorporating a fully human scFv (JCAR021) in adults with R/R B-ALL (NCT03103971).

Australian automotive workers and community leaders interview dataset following 2017 assembly plant closures.

The Australian manufacturing sector saw the exit of the automotive industry in 2017 arising in mass retrenchment across its assembly plants and supply chain firms. In 2019, a large-scale program of research was launched to investigate the impacts of the closures on workers and community including a dedicated stream of qualitative work which took place in 2021. This work took the form of in-depth interviews that investigated the experiences of automotive workers as they underwent retrenchment, reskilling, re-employment and retirement.

Digital humanistic program to manage premature frailty in young breast cancer survivors with gender perspective.

Premature frailty is a critical challenge for young breast cancer survivors (YBCSs), impacting their health and perpetuating gender inequality through heightened vulnerability and marginalization. While digital health shows promise in frailty screening, its effectiveness for comprehensively managing frailty remains inconclusive. This randomized controlled trial, registered at the Chinese Clinical Trial Registry (ChiCTR2200058823), tests the "AI-TA" program's efficacy on premature frailty and quality of life in YBCSs.

Integrating post-validation surveillance of lymphatic filariasis with the WHO STEPwise approach to non-communicable disease risk factor surveillance in Niue, a study protocol.

Background: Lymphatic filariasis (LF), a mosquito-borne parasitic disease caused by three species of filarial worms, was first detected in Niue, a small Pacific Island nation of approximately 1,600 people, in 1954. After extensive efforts involving multiple rounds of Mass Drug Administration, Niue was validated by the World Health Organization (WHO) as having e4liminated LF as a public health problem in 2016. However, no surveillance has been conducted since validation to confirm infection rates have remained below WHO's elimination threshold.

Gel polymer electrolytes based on sulfonamide functional polymer nanoparticles for sodium metal batteries.

In this work, we investigate the development of polymer electrolytes for sodium batteries based on sulfonamide functional polymer nanoparticles (NaNPs). The synthesis of the polymer NaNPs is carried out by emulsion copolymerization of methyl methacrylate and sodium sulfonamide methacrylate in the presence of a crosslinker, resulting in particle sizes of 50 nm, as shown by electron microscopy. Then, gel polymer electrolytes are prepared by mixing polymer NPs and different organic plasticizers including carbonates, glymes, sulfolanes and ionic liquids.

Brain RNA profiling highlights multiple disease pathways in persons with HAND: uncovering determinants of biotype diversity.

Objective: To discover microRNA (miRNA)-RNA transcript interactions dysregulated in brains from persons with HIV-associated neurocognitive disorder (HAND), we investigated RNA expression using machine learning tools.

Design: Brain-derived host RNA transcript and miRNA expression was examined from persons with or without HAND using bioinformatics platforms.

Methods: By combining next generation sequencing, droplet digital (dd)PCR quantitation of HIV-1 genomes, with bioinformatics and statistical tools, we investigated differential RNA expression in frontal cortex from persons without HIV (HIV[-]), with HIV without brain disease (HIV[+]), with HIV-associated neurocognitive disorder (HAND), or HAND with encephalitis (HIVE).

Therapeutic blockade of CCL17 in obesity-exacerbated osteoarthritic pain and disease.

Objectives: We previously reported that CCL17 gene-deficient mice are protected from developing pain-like behaviour and exhibit less disease in destabilization of medial meniscus (DMM)-induced OA, as well as in high-fat diet (HFD)-exacerbated DMM-induced OA. Here, we explored if therapeutic neutralization of CCL17, using increasing doses of a neutralizing monoclonal antibody (mAb), would lead to a dose-dependent benefit in these two models.

Design: DMM-induced OA was initiated in male mice either fed with a control diet (7% fat) or 8 weeks of a 60% HFD, followed by therapeutic intraperitoneal administration (i.

Closed Management of a Bent Tibial Nail: Can Revision Be Avoided?: A Case Report.

Case: A 49-year-old gentleman sustained a closed, right tibia peri-implant fracture with a bent intramedullary nail. This resulted in a 17° valgus and 5° recurvatum deformity with fracture at the distal third of the tibial shaft. The patient underwent closed manipulation with an F-Tool and was reviewed by our unit over the following year.

Mitochondrial segmentation and function prediction in live-cell images with deep learning.

Mitochondrial morphology and function are intrinsically linked, indicating the opportunity to predict functions by analyzing morphological features in live-cell imaging. Herein, we introduce MoDL, a deep learning algorithm for mitochondrial image segmentation and function prediction. Trained on a dataset of 20,000 manually labeled mitochondria from super-resolution (SR) images, MoDL achieves superior segmentation accuracy, enabling comprehensive morphological analysis.

Population attributable fractions for modifiable risk factors of neonatal, infant, and under-five mortality in 48 low- and middle-income countries.

Background: Identifying the modifiable risk factors for childhood mortality using population-attributable fractions (PAFs) estimates can inform public health planning and resource allocation in low- and middle-income countries (LMICs). We estimated PAFs for key population-level modifiable risk factors of neonatal, infant, and under-five mortality in LMICs.

Methods: We used the most recent Demographic and Health Survey data sets (2010-22) from 48 LMICs, encompassing 35 sub-Saharan African countries and 13 countries from South and Southeast Asia (n = 506 989).

Trials and tribulations: a qualitative exploration of researcher perspectives on navigating the challenges of health system implementation research.

Objective: While researchers are crucial to the successful delivery of implementation trials, their perspectives are rarely captured in the evaluation of these trials. This qualitative study aimed to capture the experiences of a small research team coordinating a large, multisite implementation trial (the Hide and Seek Project) in the Australian healthcare setting.

Design: A qualitative approach was used, whereby members of the Hide and Seek Project research team were invited to take part in semistructured focus groups led by an external facilitator.

Patient preferences for drug therapy in inflammatory arthritis: protocol for a living systematic review and evidence map to inform clinical practice guidelines.

Introduction: The pharmacological management of inflammatory arthritis often requires choices that involve trade-offs between benefits, risks and other attributes such as administration route, frequency and cost. This living systematic review aims to inform international clinical guidelines on inflammatory arthritis by creating an evidence map of patient preference studies concerning the trade-offs in pharmacological management of inflammatory arthritis.

Methods And Analysis: We will include published and peer-reviewed full-text studies in any language that quantitatively assess preferences of patients for the pharmacological management of inflammatory arthritis (rheumatoid arthritis, spondyloarthritis and juvenile idiopathic arthritis).

Effectiveness of a physiotherapist-led triage and treatment service on WAITing time for adults with musculoskeletal pain referred to Australian public hospital physiotherapy clinics: a protocol for the WAIT-less trial.

Introduction: Musculoskeletal pain is the second leading cause of disease burden in Australia, and there is a need to investigate new models of care to cope with the increasing demand for health services. This paper describes the protocol for a randomised controlled trial investigating whether a physiotherapist-led triage and treatment service is non-inferior for improving function at 6 months and superior for reducing treatment waiting times, compared with usual care for patients with musculoskeletal pain referred to public hospital outpatient physiotherapy clinics.

Methods And Analysis: A total of 368 participants (184 per arm) will be recruited from six public hospitals located in metropolitan Sydney, Australia.
