A number of studies have been conducted on the effects of the COVID-19 pandemic on people with epilepsy (PWE), some showing increased seizures, poorer psychosocial states, and reductions in Quality of Life (QoL). During the latter stages of COVID-19, well before the UN declared an end to the state of emergency, our study was conducted in Australia of a sample of women and men ≥ 18 years. The study was based on Wave 6 of the Australian Epilepsy Longitudinal Study (AELS).

Introduction: Osteoarthritis is the commonest form of chronic joint pain, which patients often self-manage before seeking healthcare advice. Patients frequently seek advice from community pharmacies, and a recent policy has recommended integrating community pharmacies into long-term condition pathways. This study explored community pharmacy teams' (CPs) and other healthcare professionals' (HCPs) views on community pharmacies providing an extended role for osteoarthritis management, identifying potential barriers and facilitators to this.

Background: Osteoarthritis is a common, painful and disabling long-term condition. Delivery of high-quality guideline-informed osteoarthritis care that successfully promotes and maintains supported self-management is imperative. However, osteoarthritis care remains inconsistent, including under use of core non-pharmacological approaches of education, exercise and weight loss.

Introduction: Middle-aged multidomain risk reduction interventions targeting modifiable risk factors for dementia may delay or prevent a third of dementia cases in later life. We describe the protocol of a cluster randomised controlled trial (cRCT), HAPPI MIND (Holistic Approach in Primary care for PreventIng Memory Impairment aNd Dementia). HAPPI MIND will evaluate the efficacy of a multidomain, nurse-led, mHealth supported intervention for assessing dementia risk and reducing associated risk factors in middle-aged adults in the Australian primary care setting.

Spinal muscular atrophy (SMA) is a progressive neuromuscular disease caused by biallelic pathogenic/likely pathogenic variants of the () gene. Early diagnosis via newborn screening (NBS) and pre-symptomatic treatment are essential to optimize health outcomes for affected individuals. We developed a multiplex quantitative polymerase chain reaction (qPCR) assay using dried blood spot (DBS) samples for the detection of homozygous absence of exon 7 of the gene.

Background: The internet has become a commonly used information source for people seeking to understand their health care options. However, inconsistent representation about what stem cell treatments are available and from whom, coupled with the lack of transparency about what has been shown to work or is even safe, can distract and mislead users. Given these challenges, there is a need to develop effective evidence-based tools for delivering information about health care options involving stem cells.

Background: The Melbourne Genomics Health Alliance (the Alliance) is a collaboration of leading hospitals, research and academic organisations, supported by its member organisations and the Victorian Government. The Alliance was set up by its members in 2013 to steer the translation of genomics, making it an integral part of health care in Victoria, Australia. The Community Advisory Group (CAG) was formed soon after, to give input and advice across the program.

Sturmberg and Martin's application of systems and complexity theory to understanding Universal Health Care (UHC) and Primary Health Care (PHC) is evaluated in the light of the influence of political economy on health systems. Furthermore, the role that neoliberal approaches to governance have had in creating increased inequities is seen as a key challenge for UHC. COVID-19 has emphasized long standing discrepancies in health and these disadvantages require government will and cooperation together with adequate social services to redress these discrepancies in UHC.

Article Synopsis
  • The study analyzes the relationship between pre-existing multimorbidity and the likelihood of undergoing total hip arthroplasty (THA) in patients over 70 years old with hip osteoarthritis.
  • Out of 28,025 participants, it was found that 40% underwent THA, with a median follow-up of 10 months; increased multimorbidity was linked to a decreased likelihood of receiving the surgery.
  • The findings indicate that existing health issues can affect THA decisions, even in cases where the overall benefits outweigh the risks for patients with moderate health declines.

Unlabelled: Total hip arthroplasty (THA) surgery for elderly people with multimorbidity increases the risk of serious health hazards including mortality. Whether such background morbidity reduces the clinical benefit is less clear.

Objective: To evaluate how pre-existing health status, using multiple approaches, influences risks of, and quality of life benefits from, THA.

Background: The first case of coronavirus disease 2019 (COVID-19) in Alberta, Canada, was confirmed on March 5, 2020. Because the virus testing criteria had changed significantly over this time period, we wanted to ascertain whether previous cases of COVID-19 had been missed in the province.

Methods: Our aim was to retrospectively evaluate specimens submitted for respiratory virus testing from December 1, 2019, through March 7, 2020, for undetected severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections before the first confirmed case.

Sturmberg and Martin in 2020 argue that universal health coverage (UHC) is mainly about financing, and primary health care (PHC) is about the right care at the right time to ensure health. They maintain that the World Health Organization has recently sent the wrong message about the "pillars" of PHC in their relationship to UHC. An understanding of political economy is required in order to come to terms with the bases of PHC and the fundamentals of UHC that dealing with inequities is not only an economic issue but fundamentally a political issue.

Aim: Research examining quality of life (QoL) among people living with epilepsy (PWE) consistently highlights the detrimental impact of stigma, anxiety, and depression, as well as the dynamic and changing nature of QoL over time. This paper represents the first panel study of the Australian Epilepsy Longitudinal Survey (AELS), examining factors that influence the QoL of PWE over a six-year interval, particularly focusing on experiences of stigma, depression, and anxiety.

Methods: Ninety-two adults participated in both Wave 2 (T1; 2010) and Wave 4 (T2; 2016/17) of the AELS.

A literature review was undertaken in 2019 to review research into the effectiveness of peer support in chronic disease self-management. As with an earlier literature review, we found the results disappointing due to poor reporting and poor research design. Lack of information on training of peer supporters, unrealistically short timeframes to produce changes in health behaviors, and lack of any theoretical underpinning of the research design contributed to rating randomized controlled trials as poor to medium quality evidence.
