Objective: Sub-optimal care of people living with dementia has serious consequences for older populations. The 2021 Australian Royal Commission noted that a large proportion of older adults in aged care live with dementia, yet there are limitations in the knowledge and understanding of staff who care for them. In the pursuit of educating pharmacists, physicians, allied health care professionals, researchers, academics, people living with dementia and their carers, and the public, who are facing the challenges of dementia management, the 'Best Practice in Dementia Health Care' conference was held on November 10, 2022 at Western Health (Sunshine Hospital, Melbourne, Australia).

We are developing an economic model to explore multiple topics in Australian youth mental health policy. To help make that model more readily transferable to other jurisdictions, we developed a software framework for authoring modular computational health economic models (CHEMs) (the software files that implement health economic models). We specified framework user requirements for: a simple programming syntax; a template CHEM module; tools for authoring new CHEM modules; search tools for finding existing CHEM modules; tools for supplying CHEM modules with data; reproducible analysis and reporting tools; and tools to help maintain a CHEM project website.

Background: Women with polycystic ovary syndrome (PCOS) experience general and PCOS-specific barriers that limit their engagement with exercise and contribute to high attrition from exercise programs, hindering the potential benefits of exercise to address their increased cardio-metabolic risk. A positive remembered affective response can predict future intentions and adherence to exercise prescription.

Objectives: To compare the longitudinal changes in remembered affect to high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) in women with PCOS and to determine whether longitudinal changes in remembered affect are correlated with changes in fitness, body mass index, adherence and exercise enjoyment.

Environmental factors, such as elevated temperature, can have varying effects on hosts and their parasites, which can have consequences for the net outcome of this relationship. The individual direct effects of temperature must be disentangled to determine the net-effect in host-parasite relationships, yet few studies have determined the net-effects in a multi-host system. To address this gap, we experimentally manipulated temperature and parasite presence in the nests of two host species infested by parasitic blowflies (Protocalliphora sialia).

Women with PCOS have substantially greater symptoms of depression and anxiety, and a lower health-related quality of life (HRQoL) compared to women without PCOS. The aim of this study was to determine if high-intensity interval training (HIIT) could provide greater improvements in mental health outcomes than standard moderate-intensity continuous training (MICT). Twenty-nine overweight women with PCOS aged 18-45 years were randomly assigned to 12 weeks of either MICT (60-75% HR, N = 15) or HIIT (> 90% HR, N = 14).

Elite and semielite athletes commonly experience mental health concerns and disorders. Compared with men athletes, women athletes are at greater risk of a range of psychological stressors that contribute to health concerns and mental health disorders, which can impact their career satisfaction and longevity. In order to address and improve the mental health of women athletes, it is necessary to simultaneously tackle the gender specific psychosocial stressors that contribute to mental health outcomes.

Article Synopsis
  • - Osteoarthritis (OA) can be managed effectively with digital self-management strategies like exercise and education, which may enhance patient engagement due to their flexibility and cost benefits.
  • - A review of 11 randomized controlled trials showed that most digital interventions were multi-component and focused on physical activity, with adherence rates over 70% in the majority of studies, while attrition rates were typically below 20%.
  • - The findings suggest that holistic digital approaches for OA may encourage consistent participation, but further research is needed to compare these digital interventions with traditional face-to-face methods and identify factors that affect adherence.
