Background: Use of high-risk medications is common and associated with adverse effects in older adults, including those living with dementia. A Computerised Clinical Decision Support System (CCDSS) called G-MEDSS© (Goal-directed Medication Review Electronic Decision Support System) contains tools that identify medications with anticholinergic and sedative effects and align older adult's health and medication goals of care with medication management strategies.
Objectives: To describe the utility of a CCDSS called G-MEDSS in Home Medicines Review (HMR) by an accredited clinical pharmacist (ACP) using a mixed-methods process evaluation method.
Methods: A mixed-methods process evaluation was conducted as part of a nation-wide cluster-randomised clinical trial evaluating the effectiveness of implementing G-MEDSS in HMR. Data were collected from ACPs and HMR recipients (the patient) using a feedback survey (ACPs and HMR recipients) and one-on-one telephone interviews (HMR recipients). Quantitative and qualitative data were combined at the start of analysis. Content analysis of the qualitative data was conducted, and emerging categories were linked to quantitative data.
Results: Feedback surveys were completed by eight ACPs and 26 HMR recipients; 11 HMR recipients completed one-on-one telephone interviews. Overall, ACPs and HMR recipients who received the intervention reported a positive attitude towards the utility of G-MEDSS in HMR. ACPs reported that G-MEDSS enhanced their ability to make evidence-based recommendations about anticholinergic and sedative medications, and to better align HMR recommendations with HMR recipients' goals of care. However, ACPs described that it was difficult to obtain goals of care from HMR recipients. HMR recipients gave mixed reports about the ACPs consultations: some HMR recipients reported that they were engaged in discussions about their views on medications, whilst other participants reported that discussions about their concerns towards medications and goals was limited.
Conclusions: This study suggests that a CCDSS, such as G-MEDSS, demonstrates good utility to assist ACPs to identify and assess anticholinergic and sedative medications. Given the mixed feedback from the ACPs on the different components of the G-MEDSS, further refinement of these tools and their use in combination in practice may be needed.

Article Synopsis
- The study focuses on how well different AI models can predict COVID-19 vaccine responses in solid organ transplant (SOT) recipients, who are at higher risk due to weakened immune systems.
- It examines various traditional and deep learning models, concluding that a new routed LSTM model outperformed others in accuracy for predicting antibody levels 12 months post-vaccination.
- The research highlights critical factors like age and immunosuppression that affect vaccine responses, suggesting AI could help customize vaccination strategies for vulnerable populations.

Background: The impact of Home Medicines Reviews (HMRs) on long-term health outcomes among individuals receiving long-term in-home aged care services is unknown.
Objectives: To examine associations between HMR provision and hospitalization, long-term care facility (LTCF) entry and mortality among older people receiving long-term in-home aged care services.
Methods: This retrospective cohort study included individuals aged 65-105 years from three Australian states who accessed in-home aged care services between 2013 and 2017.

Introduction: Cytomegalovirus (CMV), is the most common opportunistic infection, remains a cause of life-threatening disease and allograft rejection in liver transplant (LT) recipients. The purpose of this case series is to state that CMV may lead to severe pneumonia along with other bacteria.
Methodology: CMV pneumonia was diagnosed with the thoracic computed tomography (CT) scan findings, bronchoscopic biopsy, real time quantitative Polymerase Chain Reaction (qPCR) and clinical symptoms.
Liver grafts from pediatric donors represent a small fraction of grafts transplanted into adult recipients, and their use in adults requires special consideration of donor size to prevent perioperative complications. In the past, graft weight or volume ratios have been adopted from the living donor liver transplant literature to guide clinicians; however, these metrics are not regularly available to surgeons accepting deceased donor organs. In this study, we evaluated all pediatric-to-adult liver transplants in the United Network for Organ Sharing Standard Transplant Analysis and Research database from 1987 to 2019, stratified by donor age and donor-recipient height mismatch ratio (HMR; defined as donor height/recipient height).
