Metabolic Health, Overweight or Obesity, and Lung Function in Older Australian Adults.

Few studies have explored the links between adiposity, metabolic health, and lung function. This study examined the cross-sectional association between spirometric lung function and overweight/obesity, with and without metabolic abnormalities, in older adults. The research involved 3,318 older adults from the Hunter Community Study Cohort who had a BMI of 18.

Exploring the Possible Relationship Between Mother's Dietary Intake of Tryptophan and Melatonin Levels in Her Breast Milk.

Tryptophan is an essential amino acid that is not produced in the body and can only be consumed through diet. Tryptophan is a precursor for serotonin, which, in turn, helps produce melatonin. Melatonin exhibits a circadian rhythm, peaking at night and dissipating during the day, with basal levels significantly differing between mothers.

Higher scores of the Kessler Psychological Distress Scale (K10) are associated with lower serum ergothioneine and higher serum asymmetric dimethyl-l-arginine concentrations in a cohort of middle-aged and older adults.

Background: Ergothioneine (ERT) and asymmetric dimethyl-l-arginine (ADMA) have been associated with cognitive decline and dementia in older adults, but their interplay with psychological distress remains unexplored. This study aimed to measure the serum concentrations of ERT and ADMA in a representative sample of older community-dwelling adults and to determine their association with psychological distress.

Methods: Data on clinical, lifestyle, demographic characteristics, and serum concentrations of ERT and ADMA were collected from a population-based sample of older Australian adults (mean age 65.

Effectiveness of NSW health get healthy telephone coaching in adults screened from general practices.

Background: The effectiveness of the NSW Health "Get Healthy Information and Coaching Service(Get Healthy) to facilitate weight loss on a population scale has been documented, but this was based on self-reported measures.

Background: Coronavirus 19 (COVID-19) has created complex pressures and challenges for healthcare systems worldwide; however, little is known about the impacts COVID-19 has had on regional/rural healthcare workers. The Loddon Mallee Healthcare Worker COVID-19 Study (LMHCWCS) cohort was established to explore and describe the immediate and long-term impacts of the COVID-19 pandemic on regional and rural healthcare workers.

Methods: Eligible healthcare workers employed within 23 different healthcare organisations located in the Loddon Mallee region of Victoria, Australia, were included.

Metabolic Health, Overweight or Obesity, and Depressive Symptoms among Older Australian Adults.

Background: The relationship between overweight or obesity and depressive symptoms in individuals with or without cardio-metabolic abnormalities is unclear. In a cross-sectional study we examined the odds of experiencing depressive symptoms in overweight or obese older adults with or without metabolic abnormalities.

Methods: The participants included 3318 older adults from the Hunter Community Study Cohort with a Body Mass Index (BMI) ≥ 18.

The moderating role of psychological resilience in the relationship between fear of COVID-19 and psychological distress, in a cohort of rural and regional healthcare workers. During major lockdowns in Victoria, Australia 2020-2021.

The emergence of the COVID-19 pandemic resulted in substantial pressures for healthcare workers across the world. The association between fear of COVID-19 and psychological distress, and the role of psychological resilience have gained research interest. The current study aimed to investigate the cross-sectional association between fear of COVID-19 and psychological distress, in Australian rural/regional healthcare workers and determine whether resilience modifies this association.

Physical activity and prevention of mental health complications: An umbrella review.

The potential of physical activity in preventing mental health issues has garnered interest among health professionals.

Our findings revealed a significant association between higher physical activity levels and reduced risk of depression (OR = 0.

Using Genetics to Inform Interventions Related to Sodium and Potassium in Hypertension.

Background: Hypertension is a key risk factor for major adverse cardiovascular events but remains difficult to treat in many individuals. Dietary interventions are an effective approach to lower blood pressure (BP) but are not equally effective across all individuals. BP is heritable, and genetics may be a useful tool to overcome treatment response heterogeneity.

Lactate dehydrogenase contribution to symptom persistence in long COVID: A pooled analysis.

There's critical need for risk predictors in long COVID. This meta-analysis evaluates the evidence for an association between plasma lactate dehydrogenase (LDH) and long COVID and explores the contribution of LDH to symptoms persistent across the distinct post-acute sequelae of COVID-19 (PASC) domains. PubMed, EMBASE, Web of Science, and Google Scholar were searched for articles published up to 20 March 2023 for studies that reported data on LDH levels in COVID-19 survivors with and without PASC.

A systematic review and meta-analysis of long-term sequelae of COVID-19 2-year after SARS-CoV-2 infection: A call to action for neurological, physical, and psychological sciences.

Long-term sequelae conditions of COVID-19 at least 2-year following SARS-CoV-2 infection are unclear and little is known about their prevalence, longitudinal trajectory, and potential risk factors. Therefore, we conducted a comprehensive meta-analysis of survivors' health-related consequences and sequelae at 2-year following SARS-CoV-2 infection. PubMed/MEDLINE, CENTRAL, and EMBASE were systematically searched up to February 10, 2023.

Design: Prospective cohort study with median follow-up of 9.7 years.

Multi-trait genome-wide association study of opioid addiction: OPRM1 and beyond.

Opioid addiction (OA) is moderately heritable, yet only rs1799971, the A118G variant in OPRM1, has been identified as a genome-wide significant association with OA and independently replicated. We applied genomic structural equation modeling to conduct a GWAS of the new Genetics of Opioid Addiction Consortium (GENOA) data together with published studies (Psychiatric Genomics Consortium, Million Veteran Program, and Partners Health), comprising 23,367 cases and effective sample size of 88,114 individuals of European ancestry. Genetic correlations among the various OA phenotypes were uniformly high (r > 0.

Associations between three diet quality indices, genetic risk and body composition: A prospective cohort study.

Background & Aims: Diet and genetic predisposition to adiposity are independent predictors of body composition, yet few cohort studies have examined the association between overall diet quality indices, genetic risk and body composition. This study examined the prospective association of three diet quality indices and a polygenic risk score (PRS) with trunk fat mass, total fat mass, lean mass and bone mineral content.

Methods: Adults from UK Biobank cohort were included.

The effect of zinc supplementation on glucose homeostasis: a randomised double-blind placebo-controlled trial.

Aims: The burden and health costs of Type 2 Diabetes Mellitus continue to increase globally and prevention strategies in at-risk people need to be explored. Previous work, in both animal models and humans, supports the role of zinc in improving glucose homeostasis. We, therefore, aimed to test the effectiveness of zinc supplementation on glycaemic control in pre-diabetic adults.

Causal association pathways between fetuin-A and kidney function: a mediation analysis.

Objective: Body mass index (BMI), uric acid, diabetes mellitus, and hypertension are risk factors for reduced kidney function and are associated with fetuin-A levels, but their causal pathways remain unclear. The objective of this study was to investigate this knowledge gap.

Methods: A repeated cross-sectional design was used to assess causal pathway effects of fetuin-A on the estimated glomerular filtration rate (eGFR), which is mediated through BMI, uric acid, diabetes mellitus, and hypertension.

Using the AUSDRISK score to screen for pre-diabetes and diabetes in GP practices: a case-finding approach.

Objective: To identify the optimal AUSDRISK threshold score to screen for pre-diabetes and diabetes.

Methods: A total of 406 adult patients not diagnosed with diabetes were screened in General Practices (GP) between May and October 2019. All patients received a point of care (POC) HbA1c test.

Serum L-arginine and endogenous methylarginine concentrations predict irritable bowel syndrome in adults: A nested case-control study.

Unlabelled: BACKGROUND & AIMS: Nitric oxide, a major inhibitory nonadrenergic, noncholinergic neurotransmitter that relaxes smooth muscle, may be implicated in the pathophysiology of visceral hypersensitivity in irritable bowel syndrome (IBS). Impaired bioavailability of the nitric oxide precursor molecule L-arginine and higher concentrations of methylarginines (endogenous inhibitors of nitric oxide synthesis) are known to impair nitric oxide synthesis in numerous gastrointestinal cell types. We therefore examined serum concentrations of L-arginine and the methylarginines in a nested case-control study, to assess whether these factors are associated with adult IBS.

Irritable bowel syndrome and risk of glaucoma: An analysis of two independent population-based cohort studies.

Objective: Irritable bowel syndrome (IBS) is a chronic disorder associated with an abnormal gastrointestinal microbiome. Microbiome-host interactions are known to influence organ function including in the central nervous system; thus, we sought to identify whether IBS may be a risk factor for the development of glaucoma.

Design: Two prospective cohort studies.

Loddon Mallee healthcare worker COVID-19 study-protocol for a prospective cohort study examining the health and well-being of rural Australian healthcare workers during the COVID-19 pandemic.

Introduction: The COVID-19 pandemic is creating immense psychosocial disturbance. While global, broad-based research is being conducted, little is known about the effects of the COVID-19 pandemic on health and well-being or how protective and resilience factors influence the human response in Australian rural and regional communities. Rural and regional communities often have less resources to deal with such public health emergencies and face additional environmental adversity.

Discovery Genome-Wide Association Study of Body Composition in 4,386 Adults From the UK Biobank's Pilot Imaging Enhancement Study.

Body composition (fat, skeletal muscle and bone mass) is an important determinant of overall health and risk of endocrine disorders such as type 2 diabetes and osteoporosis. Although diet and physical activity are strongly implicated, body composition is also heritable. We conducted a discovery genome-wide association study on 31 phenotypes from the three-compartment body composition model (fat, lean and bone mass) in a set of 4 386 individuals (n = 2 109 males, n = 2 294 females) from the UK Biobank pilot imaging enhancement program that underwent a dual energy X-ray absorptiometry (DXA) scan for assessment of body composition and genetic screening.

Diet Quality and Cognitive Performance in Australian Adults Aged 55-85 Years: A Cross-Sectional Analysis of the Hunter Community Study Cohort.

There is a lack of evidence to determine if diet quality is associated with cognitive performance in older adults. Therefore, the aim of this study was to examine whether diet quality is associated with cognitive performance among older adults. A cross-sectional, secondary analysis of baseline data from the Hunter Community Study (HCS), comparing diet quality, measured using the Australian Recommended Food Score (ARFS), along with validated cognitive performance instruments the Audio Recorded Cognitive Screen (ARCS) and the Mini-Mental State Examination (MMSE) were undertaken in adults aged 55-85 years, living in Newcastle, NSW, Australia.
