COSMIC: a curated database of somatic variants and clinical data for cancer.

The Catalogue Of Somatic Mutations In Cancer (COSMIC), https://cancer.sanger.ac.uk/cosmic, is an expert-curated knowledgebase providing data on somatic variants in cancer, supported by a comprehensive suite of tools for interpreting genomic data, discerning the impact of somatic alterations on disease, and facilitating translational research. The catalogue is accessed and used by thousands of cancer researchers and clinicians daily, allowing them to quickly access information from an immense pool of data curated from over 29 thousand scientific publications and large studies. Within the last 4 years, COSMIC has substantially expanded its utility by adding new resources: the Mutational Signatures catalogue, the Cancer Mutation Census, and Actionability. To improve data accessibility and interoperability, somatic variants have received stable genomic identifiers that are associated with their genomic coordinates in GRCh37 and GRCh38, and new export files with reduced data redundancy have been made available for download.

Associations of postoperative delirium with activities of daily living in older people after major surgery: A prospective cohort study.

AIMS: To assess the association of postoperative delirium developed in the post-anaesthetic care unit (PACU) with older patients' ability to perform activities of daily living (ADL) during the first five postoperative days. BACKGROUND: Previous studies have focused on the association between postoperative delirium and long-term function decline, however the association between postoperative delirium and the ability to perform ADL, particularly in the immediate postoperative period, needs further investigation. DESIGN: A prospective cohort study. METHODS: A total of 271 older patients who underwent elective or emergency surgery at a tertiary care hospital in Victoria, Australia, participated in the study. Data were collected between July 2021 and December 2021. Delirium was assessed using the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5). The Katz Index of Independence in Activities of Daily Living (KATZ ADL) scale was used to measure ADL. ADL was assessed preoperatively and daily during the first five postoperative days. The STROBE checklist was used to report this study. RESULTS: Results showed that 44 (16.2%) patients developed new episode of delirium. Postoperative delirium was independently associated with decline in ADL (RR = 2.83, 95% CI = 2.71-2.97; p < 0.001). CONCLUSIONS: Postoperative delirium was associated with a decline in ADL among older people during the first five postoperative days. Screening for delirium in the PACU is essential to identify delirium during the early stages of postoperative period and implement a timely comprehensive plan. RELEVANCE TO CLINICAL PRACTICE: Delirium assessment of older patients in the PACU, and for at least the first five postoperative days, is strongly recommended. We also recommend engagement of patients in a focused physical and cognitive daily activity plan, particularly for older patients undergoing major surgery. PATIENT OR PUBLIC CONTRIBUTION: Patients and nurses helped in data collection at a tertiary care hospital.

Evaluation of consultation liaison psychiatry in Australian public hospitals (AU-CLS-1).

OBJECTIVE: This study aimed to determine whether consultation liaison psychiatric service (CLS) staffing within Australian public hospitals meet national and international minimum staffing standards. METHOD: Semi structured interviews were conducted with CLS Directors across Australia from August to December 2021. Data were collected on demographics, staffing, funding, hospital size and admissions. RESULTS: The majority of services did not meet minimum standards for CLS staffing. Non-medical staff outnumbered medical staff with increasing rurality. Psych-oncology CLS had the greatest resources, skill mix and service breadth. CONCLUSION: Although CLS are heterogeneous, most services are inadequately resourced to provide baseline specialist mental health care in Australian hospitals. Establishing national minimum standards for CLS staffing will facilitate uniform service development and quality care provision.

Validation of Two Screening Tools for Detecting Delirium in Older Patients in the Post-Anaesthetic Care Unit: A Diagnostic Test Accuracy Study.

(1) Background: Delirium is a common complication among surgical patients after major surgery, but it is often underdiagnosed in the post-anaesthetic care unit (PACU). Valid and reliable tools are required for improving diagnoses of delirium. The objective of this study was to evaluate the diagnostic test accuracy of the Three-Minute Diagnostic Interview for Confusion Assessment Method (3D-CAM) and the 4A's Test (4AT) as screening tools for detection of delirium in older people in the PACU. (2) Methods: A prospective diagnostic test accuracy study was conducted in the PACU and surgical wards of a university-affiliated tertiary care hospital in Victoria, Australia. A consecutive prospective cohort of elective and emergency patients (aged 65 years or older) admitted to the PACU were recruited between July 2021 and December 2021 following a surgical procedure performed under general anaesthesia and expected to stay in the hospital for at least 24 h following surgery. The outcome measures were sensitivity, specificity positive predictive value and negative predictive value for 3D-CAM and 4AT. (3) Results: A total of 271 patients were recruited: 16.2% (44/271) had definite delirium. For a diagnosis of definite delirium, the 3D-CAM (area under curve (AUC) = 0.96) had a sensitivity of 100% (95% CI 92.0 to 100.0) in the PACU and during the first 5 days post-operatively. Specificity ranged from 93% (95% CI 87.8 to 95.2) to 91% (95% CI 85.9 to 95.2) in the PACU and during the first 5 days post-operatively. The 4AT (AUC = 0.92) had a sensitivity of 93% (95% CI 81.7 to 98.6) in the PACU and during the first 5 days post-operatively, and specificity ranged from 89% (95% CI 84.6 to 93.1) to 87% (95%CI 80.9 to 91.8) in the PACU and during the first 5 days post-operatively. (4) Conclusions: The 3D-CAM and the 4AT are sensitive and specific screening tools that can be used to detect delirium in older people in the PACU. Screening with either tool could have an important clinical impact by improving the accuracy of delirium detection in the PACU and hence preventing adverse outcomes associated with delirium.

Working with palliative care physicians to prepare for voluntary assisted dying legislation.

OBJECTIVE: The Victorian Voluntary Assisted Dying Act 2017 (the Act) exposed a spectrum of opinions regarding euthanasia and physician-assisted suicide amongst Victorian palliative care physicians leading to sometimes acrimonious debate. The profession was unable to articulate a unified role in respect of VAD. METHOD: A collaboration between psychiatry and palliative care led to a series of group discussions in order to prepare for the Act and to re-establish professional cohesion. RESULTS: Although the meetings revealed a plurality of views regarding VAD amongst palliative care physicians, the majority were firmly against the Act. Early meetings revealed strong feelings of shock and an inability to proceed. Previous debates resurfaced between those in support and those not in support of VAD. Over time, there was increased acceptance of the need to adapt to the presence of the Act in order to limit its impact on the robust relationship with the patient central to the practice of palliative care. CONCLUSIONS: The implementation of VAD legislation requires an active process to address the challenges it represents for palliative care physicians. Collaborative facilitated meetings can help re-establish group cohesion through affirming the core principles of palliative care which remain independent of VAD.

Palliative care physicians' preparation and planning for the implementation of the Voluntary Assisted Dying Act in Victoria.

BACKGROUND: In November 2017, the Victorian Voluntary Assisted Dying (VAD) Act was passed enabling people with a progressive terminal illness to end their life voluntarily. Heated debate abounded including, to some extent within palliative care, which was also challenged with developing processes around the legislation enactment. AIM: In response, the lead author convened a series of meetings of palliative care physicians to: (i) share ideas about preparations being undertaken within services; and (ii) re-establish professional cohesion following the divide that the legislation had presented. METHODS: A series of three closed meetings were held between the legislation passage and its implementation, with all Victorian palliative care physicians invited to attend. Meetings were facilitated by an experienced psychiatrist from outside the field. RESULTS: These meetings proved very valuable as physicians collectively sought to define and respond to challenges, simultaneously reflecting on the personal and professional implications for individuals and the field. Key areas raised including gauging institutional 'readiness' for the legislation through staff surveys; the educational role of palliative care staff of the legislation implications; communication skills training; the role (if any) of palliative care in the processes of VAD; and the perceptions of palliative care itself in health services and the community. It was during the processes of discussing challenges and sharing solutions that the attendees appeared to reaffirm their professional interconnections. CONCLUSION: A description of the key elements of these discussions may be useful to others who may yet face similar circumstances with the introduction of VAD legislation.

Progressive multifocal leukoencephalopathy associated with a lymphoproliferative disorder treated with pembrolizumab.

Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease affecting the central nervous system as a result of reactivation of the John Cunningham (JC) polyomavirus and occurs almost exclusively in immunosuppressed individuals. The disease course of PML is variable but usually progressive and often fatal. Treatment is predominantly focused on immune restoration, although this is difficult to do outside of human immunodeficiency virus-associated PML. A recent case series demonstrated a potential role for programmed cell death protein 1 (PD-1) inhibitors, such as pembrolizumab, to contain and/or clear JC virus. Herein, we discuss the first reported Australian case of a 61-year-old female with PML secondary to chemoimmunotherapy demonstrating complete clearance of JC virus as well as clinical and radiological stabilisation following pembrolizumab treatment.

Liaison psychiatry in a central nervous system tumor service.

BACKGROUND: Tumors of the central nervous system (CNS) have physical and psychological effects that commonly interact and change over time. Although well suited to addressing problems at the interface between physical and psychological medicine, the role of the consultation-liaison psychiatrist has not been previously described in the management of these patients. The purpose of this paper is to summarize the experience of psychiatry liaison attachment within a CNS tumor service and to reflect on its utility within a complex multidisciplinary environment. METHODS: A retrospective file review was performed on all cases seen by a psychiatrist in a CNS tumor service over the previous 5 years. A simple thematic inductive analysis was conducted of the common problems experienced by patients and their management by the psychiatrist and within the team. RESULTS: Five common themes were identified: (i) facilitating adaptation to diagnosis; (ii) supporting living with lower-grade tumors; (iii) managing mental disorders; (iv) neuropsychiatric symptoms of tumor progression; and (v) grief and uncertainty in the advanced stages of illness. The capacity of the psychiatrist to understand and integrate the clinical, pathological, radiological, and treatment information, in communication with colleagues, helped address these challenges. CONCLUSIONS: Psychological challenges in CNS tumor patients have both psychological and neurological underpinnings. In our experience, the addition of a liaison psychiatrist to a CNS tumor service was efficient and effective in improving patient management and led to enhanced communication and decision-making within the team.

Facilitating small group learning in the operating department.

Optimising learning in the operating department is crucial to ensure that all staff are appropriately skilled and knowledgeable in their sphere of practice. Learning in small groups is popular and a good use of limited resources for professional development. This paper explores three types of small groups and how this type of facilitation can be used in the operating department.
