RESUMEN

Drug repurposing requires distinguishing established drug class targets from novel molecule-specific mechanisms and rapidly derisking their therapeutic potential in a time-critical manner, particularly in a pandemic scenario. In response to the challenge to rapidly identify treatment options for COVID-19, several studies reported that statins, as a drug class, reduce mortality in these patients. However, it is unknown if different statins exhibit consistent function or may have varying therapeutic benefit. A Bayesian network tool was used to predict drugs that shift the host transcriptomic response to SARS-CoV-2 infection towards a healthy state. Drugs were predicted using 14 RNA-sequencing datasets from 72 autopsy tissues and 465 COVID-19 patient samples or from cultured human cells and organoids infected with SARS-CoV-2. Top drug predictions included statins, which were then assessed using electronic medical records containing over 4,000 COVID-19 patients on statins to determine mortality risk in patients prescribed specific statins versus untreated matched controls. The same drugs were tested in Vero E6 cells infected with SARS-CoV-2 and human endothelial cells infected with a related OC43 coronavirus. Simvastatin was among the most highly predicted compounds (14/14 datasets) and five other statins, including atorvastatin, were predicted to be active in > 50% of analyses. Analysis of the clinical database revealed that reduced mortality risk was only observed in COVID-19 patients prescribed a subset of statins, including simvastatin and atorvastatin. In vitro testing of SARS-CoV-2 infected cells revealed simvastatin to be a potent direct inhibitor whereas most other statins were less effective. Simvastatin also inhibited OC43 infection and reduced cytokine production in endothelial cells. Statins may differ in their ability to sustain the lives of COVID-19 patients despite having a shared drug target and lipid-modifying mechanism of action. These findings highlight the value of target-agnostic drug prediction coupled with patient databases to identify and clinically evaluate non-obvious mechanisms and derisk and accelerate drug repurposing opportunities.

RESUMEN

Preterm labor (PTL) is the leading cause of neonatal morbidity and mortality worldwide. Whereas many studies have investigated the maternal immune responses that cause PTL, fetal immune cell activation has recently been raised as an important contributor to the pathogenesis of PTL. In this study, we analyzed lymphocyte receptor repertoires in maternal and cord blood from 14 term and 10 preterm deliveries, hypothesizing that the high prevalence of infection in patients with PTL may result in specific changes in the T cell and B cell repertoires. We analyzed TCR ß-chain (TCR-ß) and IgH diversity, CDR3 lengths, clonal sharing, and preferential usage of variable and joining gene segments. Both TCR-ß and IgH repertoires had shorter CDR3s compared with those in maternal blood. In cord blood samples, we found that CDR3 lengths correlated with gestational age, with shorter CDR3s in preterm neonates suggesting a less developed repertoire. Preterm cord blood displayed preferential usage of a number of genes. In preterm pregnancies, we observed significantly higher prevalence of convergent clones between mother/baby pairs than in term pregnancies. Together, our results suggest the repertoire of preterm infants displays a combination of immature features and convergence with maternal TCR-ß clones compared with that of term infants. The higher clonal convergence in PTL could represent mother and fetus both responding to a shared stimulus like an infection. These data provide a detailed analysis of the maternal-fetal immune repertoire in term and preterm patients and contribute to a better understanding of neonate immune repertoire development and potential changes associated with PTL.

RESUMEN

OPINION STATEMENT: In considering the impact of medically hastened death (MHD) on cancer care, a wide range of variables needs to be considered including demographic factors, diagnoses, local cultural factors, and the legislative frameworks in place. Here, we present a synthesis of recently available published literature and empirical data collected following legislative change to enable MHD in Victoria, Australia to explore in detail the potential impact of MHD on cancer care with a focus on patients/families and professional groups. Our findings reveal that for patients and families, both physical and existential distress frequently underlie MHD requests, with the latter less readily recognised by health professionals. The responses of those around the patient making the request may have a very significant impact on relationships within families and upon the nature of the subsequent bereavement. For palliative care, while differing views may remain, it appears that there has been some accommodation of MHD into or alongside practice over time. The recognition of a shared commitment to relief of suffering of palliative care and MHD appears a helpful means of establishing how these practices may co-exist. In cancer practice more broadly, as individual professionals reflect upon their own roles, new relationships and pathways of patient movement (or referral) must be established in response to patients' requests. Our findings also highlight many unanswered questions in understanding the impact of MHD, including that upon those dying who choose not to access MHD, First Nations peoples, the participating health professionals' longer term, and the relief of suffering itself. A systematic approach to the evaluation of MHD legislation must be adopted in order to understand its full impact. Only then could it be determined if the aspirations for such legislative change were being met.

RESUMEN

BACKGROUND: Despite global support, there remain gaps in the integration of early palliative care into cancer care. The methods of implementation whereby evidence of benefits of palliative care is translated into practice deserve attention. AIM: To identify implementation frameworks utilised in integrated palliative care in hospital-based oncology services and to describe the associated enablers and barriers to service integration. DESIGN: Systematic review with a narrative synthesis including qualitative, mixed methods, pre-post and quasi experimental designs following the guidance by the Centre for Reviews and Dissemination (PROSPERO registration CRD42021252092). DATA SOURCES: Six databases searched in 2021: EMBASE, EMCARE, APA PsycINFO, CINAHL, Cochrane Library and Ovid MEDLINE searched in 2023. Included were qualitative or quantitative studies, in English language, involving adults >18 years, and implementing hospital-based palliative care into cancer care. Critical appraisal tools were used to assess the quality and rigour. RESULTS: Seven of the 16 studies explicitly cited the use of frameworks including those based on RE-AIM, Medical Research Council evaluation of complex interventions and WHO constructs of health service evaluation. Enablers included an existing supportive culture, clear introduction to the programme across services, adequate funding, human resources and identification of advocates. Barriers included a lack of communication with the patients, caregivers, physicians and palliative care team about programme goals, stigma around the term 'palliative', a lack of robust training, or awareness of guidelines and undefined staff roles. CONCLUSIONS: Implementation science frameworks provide a method to underpin programme development and evaluation as palliative care is integrated within the oncology setting.

RESUMEN

BACKGROUND: Identifying pregnancies at risk for preterm birth, one of the leading causes of worldwide infant mortality, has the potential to improve prenatal care. However, we lack broadly applicable methods to accurately predict preterm birth risk. The dense longitudinal information present in electronic health records (EHRs) is enabling scalable and cost-efficient risk modeling of many diseases, but EHR resources have been largely untapped in the study of pregnancy. METHODS: Here, we apply machine learning to diverse data from EHRs with 35,282 deliveries to predict singleton preterm birth. RESULTS: We find that machine learning models based on billing codes alone can predict preterm birth risk at various gestational ages (e.g., ROC-AUC = 0.75, PR-AUC = 0.40 at 28 weeks of gestation) and outperform comparable models trained using known risk factors (e.g., ROC-AUC = 0.65, PR-AUC = 0.25 at 28 weeks). Examining the patterns learned by the model reveals it stratifies deliveries into interpretable groups, including high-risk preterm birth subtypes enriched for distinct comorbidities. Our machine learning approach also predicts preterm birth subtypes (spontaneous vs. indicated), mode of delivery, and recurrent preterm birth. Finally, we demonstrate the portability of our approach by showing that the prediction models maintain their accuracy on a large, independent cohort (5978 deliveries) from a different healthcare system. CONCLUSIONS: By leveraging rich phenotypic and genetic features derived from EHRs, we suggest that machine learning algorithms have great potential to improve medical care during pregnancy. However, further work is needed before these models can be applied in clinical settings.

RESUMEN

BACKGROUND: Mature evidence exists supporting the integration of palliative care in cancer care, but translation of evidence into practice is less well understood. AIM: We sought to understand current access to palliative care and its timing for people with cancer and to compare practices over time. DESIGN: We conducted a retrospective population cohort study using routinely collected administrative health data sets in Victoria, Australia. SETTING/PARTICIPANTS: All adult cancer decedents in 2018 were identified and clinical, demographic, palliative care access and quality of end of life care indices collected.Comparisons between a historic cohort of lung, breast and prostate cancer patients who died between the years 2005 and 2009 and those with these diagnoses in the current cohort. RESULTS: In 2018 there were 10,245 Victorian decedents with a cancer-coded cause of death, of these 3689 had lung, prostate or breast cancer. In 2018, access to palliative care increased (66% vs 54%) and greater numbers accessed palliative care more than 3 months before death (18% vs 10%) than in 2005-2009. Indices of end of life quality improved across most domains. However the median time between first palliative care and death was shorter in 2018 (22 vs 25 days) and more people first accessed palliative care in the hospitalisation during which they died (43% vs 33%). CONCLUSION: Despite established benefits of early palliative care, the important task of translation of this evidence into practice remains.

RESUMEN

BACKGROUND: COVID-19 has led to challenges in providing effective and timely communication in healthcare. Services have been required to adapt and evolve as successful communication remains core to high-quality patient-centred care. AIM: To describe the communication between admitted patients, their families and clinicians (medical, nursing, allied health) during end-of-life care. METHODS: This retrospective review included all patients (n = 230) who died directly due to COVID-19 at five Melbourne hospitals between 1 January and 31 December 2020. Contacts and modality used (face to face, video, telephone) during the 8 days prior to death were recorded. RESULTS: Patients were predominantly elderly (median age 86 years) and from residential aged care facilities (62%; n = 141). Communication frequency increased the closer the patient was to death, where on day of death, contact between clinicians and patients was 93% (n = 213) clinicians and families 97% (n = 222) and between patients and families 50% (n = 115). Most contact between patients and families was facilitated by a clinician (91.3% (n = 105) day of death) with the most commonly used mode being video call (n = 30 day of death). CONCLUSION: This study is one of the first and largest Australian reports on how communication occurs at the end of life for patients dying of COVID-19. Contact rates were relatively low between patients and families, compared with other cohorts dying from non-COVID-19 related causes. The impact of this difference on bereavement outcomes requires surveillance and attention.

RESUMEN

BACKGROUND: People with dementia have unique palliative and end-of-life needs. However, access to quality palliative and end-of-life care for people with dementia living in nursing homes is often suboptimal. There is a recognised need for nursing home staff training in dementia-specific palliative care to equip them with knowledge and skills to deliver high quality care. OBJECTIVE: The primary aim was to evaluate the effectiveness of a simulation training intervention (IMPETUS-D) aimed at nursing home staff on reducing unplanned transfers to hospital and/or deaths in hospital among residents living with dementia. DESIGN: Cluster randomised controlled trial of nursing homes with process evaluation conducted alongside. SUBJECTS & SETTING: One thousand three hundred four people with dementia living in 24 nursing homes (12 intervention/12 control) in three Australian cities, their families and direct care staff. METHODS: Randomisation was conducted at the level of the nursing home (cluster). The allocation sequence was generated by an independent statistician using a computer-generated allocation sequence. Staff from intervention nursing homes had access to the IMPETUS-D training intervention, and staff from control nursing homes had access to usual training opportunities. The predicted primary outcome measure was a 20% reduction in the proportion of people with dementia who had an unplanned transfer to hospital and/or death in hospital at 6-months follow-up in the intervention nursing homes compared to the control nursing homes. RESULTS: At 6-months follow-up, 128 (21.1%) people with dementia from the intervention group had an unplanned transfer or death in hospital compared to 132 (19.0%) residents from the control group; odds ratio 1.14 (95% CI, 0.82-1.59). There were suboptimal levels of staff participation in the training intervention and several barriers to participation identified. CONCLUSION: This study of a dementia-specific palliative care staff training intervention found no difference in the proportion of residents with dementia who had an unplanned hospital transfer. Implementation of the intervention was challenging and likely did not achieve adequate staff coverage to improve staff practice or resident outcomes.

RESUMEN

BACKGROUND: Chronic heart failure has a high mortality and early provision of palliative care supports complex decision-making and improves quality of life. AIM: To explore whether and when a palliative approach was adopted during the last 12 months of life in patients who experienced an in-hospital death from heart failure. DESIGN: Retrospective medical record review of all deaths from chronic heart failure (January 2010 to December 2019). PARTICIPANTS: Admissions with chronic heart failure resulting in death were analysed from an Australian tertiary referral centre. RESULTS: The cohort (n=517) were elderly (median age 83.8 years IQR=77.6-88.7) and male (55.1%). Common comorbidities were ischaemic heart disease (n=293 56.7%) and atrial fibrillation (n=289 55.9%). Life sustaining interventions occurred in 97 (18.8%) patients. In 31 (6.0%) patients referral to specialist palliative care occurred prior to, and in 263 (50.9%) during, the terminal admission. Opioids were prescribed to 440 (85.1%) patients. Comfort care was the documented goal in 158 patients (30.6%). A palliative approach was significantly associated with prior admission in the preceding 12 months (OR=1.5 95% CI=1.0-2.1 p<0.043), receiving outpatient care (OR=2.6 95% CI=1.6-4.1 p<0.01), and admissions in the latter half of the decade (OR=1.5 95% CI=1.0-2.0 p<0.038). CONCLUSION: Despite greater adoption of a palliative approach in the terminal admission over the last decade, a significant proportion of patients receive palliative care late, just prior to death.

RESUMEN

BACKGROUND: The Responding to Urgency of Need in Palliative Care (RUN-PC) Triage Tool is a novel, evidence-based tool by which specialist palliative care services can manage waiting lists and workflow by prioritising access to care for those patients with the most pressing needs in an equitable, efficient and transparent manner. AIM: This study aimed to establish the intra- and inter-rater reliability, and convergent validity of the RUN-PC Triage Tool and generate recommended response times. DESIGN: An online survey of palliative care intake officers applying the RUN-PC Triage Tool to a series of 49 real clinical vignettes was assessed against a reference standard: a postal survey of expert palliative care clinicians ranking the same vignettes in order of urgency. SETTING/PARTICIPANTS: Intake officers (n = 28) with a minimum of 2 years palliative care experience and expert clinicians (n = 32) with a minimum of 10 years palliative care experience were recruited from inpatient, hospital consultation and community palliative care services across metropolitan and regional Victoria, Australia. RESULTS: The RUN-PC Triage Tool has good intra- and inter-rater reliability in inpatient, hospital consultation and community palliative care settings (Intraclass Correlation Coefficients ranged from 0.61 to 0.74), and moderate to good correlation to expert opinion used as a reference standard (Kendall's Tau rank correlation coefficients ranged from 0.68 to 0.83). CONCLUSION: The RUN-PC Triage Tool appears to be a reliable and valid tool for the prioritisation of patients referred to specialist inpatient, hospital consultation and community palliative care services.

RESUMEN

BACKGROUND: Family meetings facilitate the exploration of issues and goals of care however, there has been minimal research to determine the benefits and cost implications. AIMS: To determine: (1) if family caregivers of hospitalised patients referred to palliative care who receive a structured family meeting report lower psychological distress (primary outcome), fewer unmet needs, improved quality of life; feel more prepared for the caregiving role; and receive better quality of end-of-life care; (2) if outcomes vary dependant upon site of care and; (3) the cost-benefit of implementing meetings into routine practice. DESIGN: Pragmatic cluster randomised trial involving palliative care patients and their primary family caregivers at three Australian hospitals. Participants completed measures upon admission (Time 1); 10 days later (Time 2) and two months after the patient died (Time 3). Regression analyses, health utilisation and process evaluation were conducted. RESULTS: 297 dyads recruited; control (n = 153) and intervention (n = 144). The intervention group demonstrated significantly lower psychological distress (Diff: -1.68, p < 0.01) and higher preparedness (Diff: 3.48, p = 0.001) at Time 2. No differences were identified based on quality of end of life care or health utilisation measures. CONCLUSIONS: Family meetings may be helpful in reducing family caregiver distress and enhancing their preparedness for the caregiving role and it appears they may be conducted without increased hospital health utilisation impacts; although opportunity costs need to be considered in order to routinely offer these as a standardised intervention. Additional health economic examination is also advocated to comprehensively understand the cost-benefit implications.

RESUMEN

INTRODUCTION: Medications for osteoporosis have not been reported to reduce fracture rates in patients with spinal cord injury and disorders (SCI/D), yet these medications are still prescribed. Clinical decision-making underscoring the initiation and discontinuation of osteoporosis medications in SCI/D remains poorly understood. METHODOLOGY: Veterans with a SCI/D with at least one prescription for an osteoporosis medication (bisphosphonate, calcitonin, denosumab, raloxifene, and teriparatide) who received healthcare within Veterans Affairs (VA) from 2005 to 2015 were identified using VA administrative databases. A 10% subsample of Veterans was selected for electronic health record review. RESULTS: Two hundred and sixty-seven Veterans with 330 prescriptions underwent electronic health record review. Bisphosphonates were the most frequently prescribed medication for osteoporosis (n = 223, 67.6%). Of the 187 Veterans with prescriptions for prevention or treatment of osteoporosis, the primary reason for initiation was Dual Energy X-ray Absorptiometry (DXA) scan with osteopenia or osteoporosis (n = 119, 63.6% of Veterans), primarily at the hip (81.0% of DXAs). The majority (79.0%) of DXAs were "screening tests," with SCI/D being the sole reason for the scan. Fractures (n = 51, 27.3%) and fall risk concerns (n = 29, 15.5%) were other major reasons for initiation. On average, oral bisphosphonates were filled for <3 yr, with medication-related side effects (n = 23, 15.8% of bisphosphonates discontinued), predominately gastrointestinal (n = 17, 73.9% of reported side effects), the most common reason for discontinuation. Drug holidays occurred in 14.3% of 35 oral bisphosphonates used for ≥5 yr. No cases of osteonecrosis of the jaw were found. There was one case of an atypical femoral fracture which could not be confirmed. CONCLUSIONS: The decision to initiate pharmacological therapies in SCI/D is primarily based on osteopenia or osteoporosis at the hip by screening DXAs. Gastrointestinal side effects are the major reason for discontinuation of oral bisphosphonates. New therapies for osteoporosis in SCI/D are needed.

RESUMEN

This is a prospective, open-label, proof-of-concept study of tofacitinib, a Janus kinase inhibitor, as a steroid-sparing therapy in corticosteroid-dependent pulmonary sarcoidosis. Five patients with corticosteroid-dependent pulmonary sarcoidosis were treated with tofacitinib 5 mg twice daily. The primary endpoint was a ≥ 50% reduction in corticosteroids at week 16 with no worsening in pulmonary function or respiratory symptoms. 60% of patients (3/5) met the primary endpoint. One patient was lost to follow up prior to steroid taper, and another was withdrawn due to worsening of known neurosarcoidosis. The three patients who met the primary endpoint each tapered to ≤ 5 mg/day prednisone, respiratory symptoms improved, and spirometry remained stable. In this proof-of-concept study, the addition of a JAK-inhibitor allowed 60% of patients with pulmonary sarcoidosis to successfully taper corticosteroids. JAK-inhibitors are a promising therapy for pulmonary sarcoidosis, which require further investigation in randomized trials.Trial Registration clinicaltrials.gov NCT03793439; registered Jan 4, 2019.

RESUMEN

BACKGROUND: Descriptions of symptoms and medication use at end of life in COVID-19 are limited to small cross-sectional studies, with no Australian longitudinal data. AIMS: To describe end-of-life symptoms and care needs of people dying of COVID-19. METHODS: This retrospective cohort study included consecutive admitted patients who died at a Victorian tertiary referral hospital from 1 January to 30 September directly due to COVID-19. Clinical characteristics, symptoms and use of supportive therapies, including medications and non-pharmacological interventions in the last 3 days of life were extracted. RESULTS: The cohort comprised 58 patients (median age 87 years, interquartile range (IQR) 81-90) predominantly admitted from home (n = 30), who died after a median of 11 days (IQR 6-28) in the acute medical (n = 31) or aged care (n = 27) wards of the hospital. The median Charlson Comorbidity Score was 7 (IQR 5-8). Breathlessness (n = 42), agitation (n = 36) and pain (n = 33) were the most frequent clinician-reported symptoms in the final 3 days of life, with most requiring opioids (n = 52), midazolam (n = 40), with dose escalation commonly being required. While oxygen therapy was commonly used (n = 47), few (n = 13) required an anti-secretory agent. CONCLUSIONS: This study presents one of the first and largest Australian report of the end of life and symptom experience of people dying of COVID-19. This information should help clinicians to anticipate palliative care needs of these patients, for example, recognising that higher starting doses of opioids and sedatives may help reduce prevalence and severity of breathlessness and agitation near death.

RESUMEN

Regulatory changes now permit the availability and prescribing of medicinal cannabis in Australia. Public awareness and patient interest are high. Using a co-design approach involving cancer patients, carers and oncology and palliative care clinicians, two information resources were developed to provide readily available sources of important information for cancer patients and clinicians who are considering the use of medicinal cannabis. Focus groups and evaluation interviews revealed some areas of dissonance between consumers and clinicians concerning aspects of medicinal cannabis.

RESUMEN

BACKGROUND: Current international consensus is that 'early' referral to palliative care services improves cancer patient and family carer outcomes. In practice, however, these referrals are not routine. An approach which directly addresses identified barriers to early integration of palliative care is required. This protocol details a trial of a standardized model of early palliative care (Care Plus) introduced at key defined, disease-specific times or transition points in the illness for people with cancer. Introduced as a 'whole of system' practice change for identified advanced cancers, the key outcomes of interest are population health service use change. The aims of the study are to examine the effect of Care Plus implementation on (1) acute hospitalisation days in the last 3 months of life; (2) timeliness of access to palliative care; (3) quality and (4) costs of end of life care; and (5) the acceptability of services for people with advanced cancer. METHODS: Multi-site stepped wedge implementation trial testing usual care (control) versus Care Plus (practice change). The design stipulates 'control' periods when usual care is observed, and the process of implementing Care Plus which includes phases of planning, engagement, practice change and evaluation. During the practice change phase, all patients with targeted advanced cancers reaching the transition point will, by default, receive Care Plus. Health service utilization and unit costs before and after implementation will be collated from hospital records, and state and national health service administrative datasets. Qualitative data from patients, consumers and clinicians before and after practice change will be gathered through interviews and focus groups. DISCUSSION: The study outcomes will detail the impact and acceptability of the standardized integration of palliative care as a practice change, including recommendations for ongoing sustainability and broader implementation.

RESUMEN

STUDY DESIGN: Survey. OBJECTIVES: Managing osteoporosis in persons with chronic spinal cord injury (SCI) is difficult as little evidence exists regarding effective strategies. We examined the effect of key factors on providers' bone health management decisions in persons with SCI. SETTING: USA. METHODS: Providers reviewed blocks of 9 hypothetical cases that varied on four factors: osteoporosis, osteopenia, or normal bone mineral density using dual-energy X-ray absorptiometry (DXA); DXA region of interest (lumbar spine, hip, knee), prior lower extremity fracture; and no or limited ambulation. They indicated how likely they would recommend pharmacological management, what treatment(s) they would recommend, and whether they would request another DXA before treatment. RESULTS: Eighty-two healthcare providers completed the survey. Treatment recommendations for bisphosphonates and Vitamin D/calcium supplements, respectively, were more likely if there was a prior fracture (OR: 2.65, 95%CI: 1.76-3.99, p < 0.0001; OR: 2.96, 95%CI: 1.40-6.26, p = 0.004) and if a DXA scan found osteopenia (OR: 2.23, 95%CI: 1.41-3.54, p = 0.001; OR: 6.56, 95%CI: 2.71-15.85, p < 0.0001) or osteoporosis (OR: 12.08, 95%CI: 7.09-20.57, p < 0.0001; OR: 4.54, 95%CI: 2.08-9.90, p < 0.0001). Another DXA scan was more likely to be requested if there was a prior fracture (OR: 1.75, 95%CI: 1.10-2.78, p = 0.02) but less likely if the person was nonambulatory (OR: 0.41, 95%: 0.19-0.90, p = 0.03). CONCLUSIONS: Prior fracture and DXA findings influenced treatment recommendations for bone health management in SCI. Reliance on lumbar spine scans to determine bone loss and treatment identifies a knowledge gap for which future education is required.

RESUMEN

BACKGROUND: Historically low, the proportion of female urology residents now exceeds 25% in recent years. Self-assessment is a widely used tool to track progress in medical education. However, the validity of its results and gender differences may influence interpretation. Simulation of surgical skills is increasingly common in modern residency training and standardizes certain objective tasks and skills. The objective of this study was to identify gender differences in self-assessment of surgeons and trainees when using simulation of surgical skills. METHODS: Medical students, residents, and attending and retired surgeons completed simple interrupted suturing. Assessment was self-rated using previously tested visual analog motion scales. Tasks were video recorded and rated by blinded expert surgeons using identical motion scales. Computer vision motion tracking software was used to objectively analyze the kinematics of surgical tasks. RESULTS: Proportion of female (n = 17) and male (n = 20) participants did not differ significantly by the level of training, P = 0.76. Five expert surgeons evaluated 84 video segments of simple interrupted suturing tasks (mean 3.0 segments per task per participant). Self-assessment correlated well overall with expert rating for motion economy (Pearson correlation coefficient 0.61, P < 0.001) and motion fluidity (0.55, P = 0.002). Women underrated their performance in accordance with mean individual difference of self-assessment and expert assessment scores (Δ SAS-EAS) for both economy of motion (mean ± SEM -1.1 ± 0.38, P = 0.01) and fluidity of motion (-1.3 ± 0.39, P < 0.01). On the same measures, men tended to rate themselves in accordance with experts (-0.16 ± 0.36, P = 0.63; -0.09 ± 0.41, P = 0.82, respectively). Δ SAS-EAS did not differ significantly on any rating scale across levels of training. Expert ratings did not differ significantly by gender for any domain. CONCLUSIONS: Female surgeons and trainees underrate some technical skills on self-assessment when compared with expert ratings, whereas male surgeon and trainee self-ratings and expert ratings were similar. Further work is needed to determine if these differences are accentuated across increasingly difficult tasks.

RESUMEN

Following legislative changes in the availability and prescribing of medicinal cannabis in Australia, we sought to understand prospectively the nature of information seeking and requests for medicinal cannabis in consultations between palliative care clinicians and patients with cancer. The 104 discussions were overwhelmingly initiated by patients and carers (93%) and were for a variety of symptoms, reflecting high levels of patient interest in the use of medicinal cannabis in cancer.

RESUMEN

The Fontan circulation describes the circulatory state resulting from an operation in congenital heart disease where systemic venous return is directed to the lungs without an intervening active pumping chamber. As survival increases, so too does recognition of the potential health challenges. This document aims to allow clinicians, people with a Fontan circulation, and their families to benefit from consensus agreement about management of the person with a Fontan circulation. The document was crafted with input from a multidisciplinary group of health care providers as well as individuals with a Fontan circulation and families. It is hoped that the shared common vision of long-term wellbeing will continue to drive improvements in care and quality of life in this patient population and eventually translate into improved survival. KEYPOINTS.
