Article Synopsis
  • - Western Australia effectively managed COVID-19 public health measures, but healthcare staff still faced significant mental health risks, particularly during the pandemic's early years.
  • - A study involving 183 healthcare workers found stable rates of post-traumatic stress, depression, and anxiety over time, but those with initially lower symptoms experienced greater increases, while those with higher symptoms saw smaller declines—a phenomenon described as a "catch-up" effect.
  • - Key risk factors for psychological symptom changes included workplace stress, sleep problems, and trauma exposure, while supportive workplace and social networks helped protect mental health, indicating a need for improvements in systemic support for healthcare professionals.

Time-Restricted Eating (TRE), a form of intermittent fasting, has gained popularity for weight control and metabolic health. It is not incorporated into dietary and clinical guidelines, and hence is generally not being recommended to the public. This qualitative study explores how individuals have discovered TRE as a form of dietary practice and their motivations for practising it.

Purpose: As hearing loss is a modifiable risk factor of dementia, allied hearing-healthcare professionals (AHHPs) frequently see older patients who are affected by both conditions. However, little is known about how well Australian AHHP's understand the complexities of providing care to patients with comorbid hearing loss and dementia, as well as their associated views and practices. Thus, the current study used a survey to explore the knowledge, attitudes, and practices (KAPs) of Australian AHHPs in managing comorbid patients.

Western Australia's unique public health response delayed the first wave of community COVID-19 transmission for 2 years. We aimed to determine the status of post-traumatic stress (PTSS), depressive, and anxiety symptoms among healthcare staff in major tertiary hospitals, together with associated risk and protective factors prior to the first substantial outbreak of COVID-19. A cross-sectional study was conducted with 431 healthcare staff immediately prior to the Western Australian border re-opening in 2022.

Introduction: The demand for adolescent mental health services has increased significantly in recent years, leading to excessive wait times for adolescents seeking mental health services and poor mental health outcomes. Timely access to mental health services is critical to reducing the risk of symptom chronicity and progression to mental disorder. A better understanding of whether and how interventions to reduce wait times impact mental health outcomes is needed to guide mental health policymakers and service planners in their approach to reducing wait times.

Article Synopsis
  • - The study investigated the links between genetic variants in breast cancer susceptibility genes (besides BRCA1, BRCA2, and CHEK2) and risks of developing contralateral breast cancer (CBC) and breast cancer-specific survival (BCSS) in 34,401 women of European ancestry who had been diagnosed with breast cancer.
  • - Significant findings revealed that protein-truncating variants (PTVs) and certain missense variants (MSVs) in genes like BRCA1, BRCA2, TP53, CHEK2, and PALB2 were associated with higher CBC risk and negative impacts on BCSS, indicating that these genetic factors play a crucial role in cancer outcomes.
  • - The results showed minimal
