Identification of type 1 diabetes risk phenotypes using an outcome-guided clustering analysis.

Aims/hypothesis: Although statistical models for predicting type 1 diabetes risk have been developed, approaches that reveal the heterogeneity of the at-risk population by identifying clinically meaningful clusters are lacking. We aimed to identify and characterise clusters of islet autoantibody-positive individuals who share similar characteristics and type 1 diabetes risk.

Methods: We tested a novel outcome-guided clustering method in initially non-diabetic autoantibody-positive relatives of individuals with type 1 diabetes, using the TrialNet Pathway to Prevention study data (n=1123).

Development of person-centred quality indicators for aged care assessment services in Australia: A mixed methods study.

Introduction: This study developed a proposed set of person-centred quality indicators (PC-QIs) for services that assess older adults' care and support needs to determine their eligibility to receive government-funded aged care services in Australia. Individual proposed PC-QIs amenability for change within current organizational structures were explored. Barriers and opportunities to adapt service elements of the aged care assessment service to better align with the intent of the proposed PC-QIs were identified.

Using Organoids to Model Sex Differences in the Human Brain.

Sex differences are widespread during neurodevelopment and play a role in neuropsychiatric conditions such as autism, which is more prevalent in males than females. In humans, males have been shown to have larger brain volumes than females with development of the hippocampus and amygdala showing prominent sex differences. Mechanistically, sex steroids and sex chromosomes drive these differences in brain development, which seem to peak during prenatal and pubertal stages.

Limited evidence of a shared genetic relationship between C-reactive protein levels and cognitive function in older UK adults of European ancestry.

Introduction: Previous studies have shown associations between cognitive function and C-reactive protein (CRP) levels in older adults. Few studies have considered the extent to which a genetic predisposition for higher CRP levels contributes to this association.

Methods: Data was analyzed from 7,817 UK participants aged >50 years as part of the PROTECT study, within which adults without dementia completed a comprehensive neuropsychological battery.

Description and Cross-Sectional Analyses of 25,880 Adults and Children in the UK National Registry of Rare Kidney Diseases Cohort.

Introduction: The National Registry of Rare Kidney Diseases (RaDaR) collects data from people living with rare kidney diseases across the UK, and is the world's largest, rare kidney disease registry. We present the clinical demographics and renal function of 25,880 prevalent patients and sought evidence of bias in recruitment to RaDaR.

Methods: RaDaR is linked with the UK Renal Registry (UKRR, with which all UK patients receiving kidney replacement therapy [KRT] are registered).

AI-driven generalized polynomial transformation models for unsupervised fundus image registration.

We introduce a novel AI-driven approach to unsupervised fundus image registration utilizing our Generalized Polynomial Transformation (GPT) model. Through the GPT, we establish a foundational model capable of simulating diverse polynomial transformations, trained on a large synthetic dataset to encompass a broad range of transformation scenarios. Additionally, our hybrid pre-processing strategy aims to streamline the learning process by offering model-focused input.

Mortality of patients with COPD.

Introduction: Chronic obstructive pulmonary disease (COPD) is the third most common cause of death worldwide and 24% of the patients die within 5 years of diagnosis.

Areas Covered: The epidemiology of mortality and the interventions that reduce it are reviewed. The increasing global deaths reflect increases in population sizes, increasing life expectancy and reductions in other causes of death.

Guidance for estimating penetrance of monogenic disease-causing variants in population cohorts.

Penetrance is the probability that an individual with a pathogenic genetic variant develops a specific disease. Knowing the penetrance of variants for monogenic disorders is important for counseling of individuals. Until recently, estimates of penetrance have largely relied on affected individuals and their at-risk family members being clinically referred for genetic testing, a 'phenotype-first' approach.

Capturing the Value of Vaccination within Health Technology Assessment and Health Economics-Practical Considerations for Expanding Valuation by Including Key Concepts.

Following the development of a value of vaccination (VoV) framework for health technology assessment/cost-effectiveness analysis (HTA/CEA), and identification of three vaccination benefits for near-term inclusion in HTA/CEA, this final paper provides decision makers with methods and examples to consider benefits of health systems strengthening (HSS), equity, and macroeconomic gains. Expert working groups, targeted literature reviews, and case studies were used. Opportunity cost methods were applied for HSS benefits of rotavirus vaccination.

Biventricular responses to exercise and their relation to cardiorespiratory fitness in pediatric pulmonary hypertension.

Despite exercise intolerance being predictive of outcomes in pulmonary arterial hypertension (PAH), its underlying cardiac mechanisms are not well described. The aim of the study was to explore the biventricular response to exercise and its associations with cardiorespiratory fitness in children with PAH. Participants underwent incremental cardiopulmonary exercise testing and simultaneous exercise echocardiography on a recumbent cycle ergometer.

A novel developmental critical period of orexinergic signaling in the primary visual thalamus.

The orexinergic system of the lateral hypothalamus plays crucial roles in arousal, feeding behavior, and reward modulation. Most research has focused on adult rodents, overlooking orexins' potential role in the nervous system development. This study, using electrophysiological and molecular tools, highlights importance of orexinergic signaling in the postnatal development of the rodent dorsolateral geniculate nucleus (DLG), a primary visual thalamic center.

Pharmacists' Willingness to Offer Vaccination Services: A Systematic Review and Meta-Analysis.

Pharmacy-based vaccination (PBV) services increase coverage and enhance access to lifesaving vaccines. This systematic review assessed the proportion of pharmacists willing to offer PBV services. PubMed/MEDLINE, CINAHL, EMBASE and Scopus electronic databases were searched from inception to identify relevant literature.

"Exercise… to Me, It's Freedom": Motivation, Support, and Self-Management to Keep Physically Active with Parkinson's Disease: A Qualitative Study.

The benefits of exercise have been widely explored among people with Parkinson's (PwP). Exercise can improve non-motor (fatigue, pain, sleep, etc.) and motor features (balance, muscle strength, gait speed, etc.

What do medical students think are characteristics of a good ultrasound tutor? A qualitative study.

Purpose: This study was designed to elicit medical students' opinions on the characteristics of a good ultrasound tutor. The results should help educators to create an optimal teaching environment and inform tutor training.

Materials And Methods: The qualitative study recruited 15 participants from a larger mixed-methods study of 64 medical students who underwent a basic course on abdominal ultrasound taught by faculty and near-peer tutors.

Relationship of Body Composition With Middle Cerebral Artery Hemodynamic Using Compositional Data Analysis in Middle-Age Adults From Toledo Study for Healthy Aging.

Excess adipose tissue may promote chronic systemic inflammation and oxidative stress, causing endothelial damage. Early evidence indicates that obesity may be associated with poorer cerebral perfusion. The purpose of this study was to examine the relationship between body composition and cerebral hemodynamics.
