Palliative care (PC) in rural aged care facilities faces significant challenges, including late referrals and insufficient staff training, leading to a risk of suboptimal end-of-life care. The aim of the project was to develop and implement an evidence-based Palliative Care Assessment Toolkit (PCAT) to improve PC in rural aged care facilities and evaluate its impact on care delivery and staff practices. The study employed a mixed-methods design across three phases: codesign of the toolkit, implementation, and evaluation (using pre- and post-data).

Introduction: Recent developments in the field of large language models have showcased impressive achievements in their ability to perform natural language processing tasks, opening up possibilities for use in critical domains like telehealth. We conducted a pilot study on the opportunities of utilizing large language models, specifically GPT-3.5, GPT-4, and LLaMA 2, in the context of zero-shot summarization of doctor-patient conversation during a palliative care teleconsultation.

Aims: Body exhaust suits or surgical helmet systems (colloquially, 'space suits') are frequently used in many forms of arthroplasty, with the aim of providing personal protection to surgeons and, perhaps, reducing periprosthetic joint infections, although this has not consistently been borne out in systematic reviews and registry studies. To date, no large-scale study has investigated whether this is applicable to shoulder arthroplasty. We used the New Zealand Joint Registry to assess whether the use of surgical helmet systems was associated with lower all-cause revision or revision for deep infection in primary shoulder arthroplasties.

Article Synopsis
  • Passive administration of the monoclonal antibody cocktail CAS + IMD showed positive clinical outcomes in hospitalized COVID-19 patients, particularly those who were seronegative at the start of treatment.
  • The study involved 46 patients and used advanced immunoprofiling techniques to assess how the antibody treatment influenced immune responses over time, from October 2020 to April 2021.
  • Results indicated that CAS + IMD not only reduced acute inflammation but also enhanced recovery without harming the host's T cell immune response, suggesting a beneficial anti-inflammatory effect that needs further exploration.
