The teaching and learning of health advocacy in an Australian medical school

Objectives: To determine if medical graduates from an Australian university are educated and skilled in health advocacy for their future practice with patients and the wider community. Methods: The authors used an exploratory mixed methodology starting with curriculum mapping of the medical curriculum, followed by key informant interviews with the University of Notre Dame, School of Medicine academics (n = 6) and alumni (n = 5) on teaching/learning and practice of health advocacy. The final stage consisted of a cross-sectional survey on teaching/learning health advocacy among third and fourth (final) year medical students (N = 195). Results: The medical curriculum contained no explicit learn-ing objectives on health advocacy. Key informant interviews demonstrated an appreciation of health advocacy and its importance in the medical curriculum but a deficit in explicit and practical ‘hands on’ teaching. Survey response rate was 47% (n = 92). A majority of students (76%, n = 70) had heard of health advocacy, with this being more likely among third (92%, n = 33) compared with fourth year students (67%, n = 37) (Fisher’s Exact Test χ2 (2, N = 91) = 7.311, p = 0.02). Stu-dents reported having opportunities to observe (76%, n = 70) and practise health advocacy (50%, n = 46) in the curriculum. Conclusions: Students and medical graduates demonstrated sound recognition of the term health advocacy. Deficits identified in the curriculum include lack of explicit learning objectives and “hands-on” learning opportunities in health advocacy

Models for predicting venous thromboembolism in ambulatory patients with lung cancer:A systematic review and meta-analysis

AimsThe incidence of venous thromboembolism (VTE) in patients with lung cancer is relatively high, and risk stratification models are vital for the targeted application of thromboprophylaxis. We aimed to review VTE risk prediction models that have been developed in patients with lung cancer and evaluate their performance.Methods and resultsTwenty-four eligible studies involving 123,493 patients were included. The pooled incidence of VTE within 12 months was 11 % (95 % CI 8 %–14 %). With the identified four existing VTE risk assessment tools, meta-analyses did not show a significant discriminatory capability of stratifying VTE risk using Khorana, PROTECHT and CONKO scores. The pooled sensitivity and specificity of the Khorana score were 24 % (95 % CI 11 %–44 %) and 84 % (95 % CI 73 %–91 %) at the 3-point cut-off, and 43 % (95 % CI 35 %–52 %) and 61 % (95 % CI 52 %–69 %) at the 2-point cut-off. A COMPASS-CAT score ≥ 7 points indicated a significantly high VTE risk, with a RR of 4.68 (95 % CI 1.05–20.80).ConclusionsThe Khorana score lacked discriminatory capability in identifying patients with lung cancer at high VTE risk, regardless of the cut-off value. The COMPASS-CAT score had better performance, but further validation is needed. The results indicate the need for robust VTE risk assessment tools specifically designed and validated for lung cancer patients. Future research should include relevant biomarkers as important predictors and consider the combined use of risk tools.PROSPERO registration number: CRD42021245907

Promoting breastfeeding in women with gestational diabetes mellitus in high-income settings:an integrative review

Background: Breastfeeding provides many short- and long-term health benefits for mothers and their infants and is a particularly relevant strategy for women who experience Gestational Diabetes Mellitus (GDM) during pregnancy. However, breastfeeding rates are generally lower amongst this group of women than the general population. This review’s objective is to identify the factors that influence breastfeeding by exploring the experiences and outcomes of women in in high-income health care contexts when there is a history of GDM in the corresponding pregnancy. Methods: A comprehensive search strategy explored the electronic databases Medline, CINAHL, Web of Science and Scopus for primary studies exploring breastfeeding practices for papers published between January 2011 and June 2023. All papers were screened independently by two researchers with included papers assessed using the Crowe Critical Appraisal tool. Findings were analysed using a narrative synthesis framework. Results: From an initial search result of 1037 papers, 16 papers representing five high-income nations were included in this review for analysis – the United States of America (n = 10), Australia (n = 3), Finland (n = 1), Norway (n = 1), and Israel (n = 1). Fifteen papers used a quantitative design, and one used a qualitative design. The total number of participants represented in the papers is 963,718 of which 812,052 had GDM and 151,666 did not. Women with an immediate history of GDM were as likely to initiate breastfeeding as those without it. However, they were more likely to have the first feed delayed, be offered supplementation, experience delayed lactogenesis II and or a perception of low supply. Women were less likely to exclusively breastfeed and more likely to completely wean earlier than the general population. Maternity care practices, maternal factors, family influences, and determinants of health were contextual and acted as either a facilitator or barrier for this group. Conclusion: Breastfeeding education and support need to be tailored to recognise the individual needs and challenges of women with a history of GDM. Interventions, including the introduction of commercial milk formula (CMF) may have an even greater impact and needs to be very carefully considered. Supportive strategies should encompass the immediate and extended family who are major sources of influence.</p

Characteristics of the phenotype of mixed cardiomyopathy in patients with implantable cardioverter-defibrillators

OnlinePublBackground or Purpose The prognosis of mixed cardiomyopathy (CMP) in patients with implanted cardioverter-defbrillators (ICDs) has not been investigated. We aim to study the demographic, clinical, device therapies and survival characteristics of mixed CMP in a cohort of patients implanted with a defbrillator. Methods The term mixed CMP was used to categorise patients with impaired left ventricular ejection fraction attributed to documented non-ischemic triggers with concomitant moderate coronary artery disease. This is a single center observational cohort of 526 patients with a mean follow-up of 8.7±3.5 years. Results There were 42.5% patients with ischemic cardiomyopathy (ICM), 26.9% with non-ischemic cardiomyopathy (NICM) and 30.6% with mixed CMP. Mixed CMP, compared to NICM, was associated with higher mean age (69.1 ± 9.6 years), atrial fibrillation (55.3%) and greater incidence of comorbidities. The proportion of patients with mixed CMP receiving device shocks was 23.6%, compared to 18.4% in NICM and 27% in ICM. The VT cycle length recorded in mixed CMP (281.6 ± 43.1 ms) was comparable with ICM (282.5 ± 44 ms; p = 0.9) and lesser than NICM (297.7±48.7 ms; p=0.1). All-cause mortality in mixed CMP (21.1%) was similar to ICM (20.1%; p=0.8) and higher than NICM (15.6%; p = 0.2). The Kaplan–Meier curves revealed hazards of 1.57 (95% CI: 0.91, 2.68) for mixed CMP compared to NICM. Conclusion In a cohort of patients with ICD, the group with mixed CMP represents a phenotype predominantly comprised of the elderly with a higher incidence of comorbidities. Mixed CMP resembles ICM in terms of number of device shocks and VT cycle length. Trends of long-term prognosis of patients with mixed CMP are worse than NICM and similar to ICM.Deep Chandh Raja, Indira Samarawickrema, Sarat Krishna Menon, Rikvin Singh, Abhinav Mehta, Lukah Q.

Sun-protection practices among undergraduates at an Australian University

Background/Objectives: To assess the sun-protection practices of undergraduates at the Australian National University. Methods: We sent emails with links to the questionnaire on the use of five sun-protection practices in the last fortnight of the summer to 3341 randomly selected students aged 18-24 years in this cross-sectional study. The response rate was 19% and 507 students met the inclusion criteria. Results: The sample consisted of 338 female and 169 male students with a mean age of 20.5 years (SD±1.9). Any method of sun protection was used always or often by 32% of respondents. The commonest method used was shade (58%) while the least common was wearing a hat (8%). Domestic students (44%) used sunglasses more than the international students (23%, P<0.05) and female students used sunscreen (48%) and sunglasses (37%) more than male students (33% and 23% respectively) (P<0.05). In the 22-24-year-old age group non-medical students (54%) used sunglasses more than the medical students (36%, P<0.05). Conclusions: Only a third of the sample practiced any method of sun protection and there were significant differences in the practices between subgroups, suggesting they were at an increased risk of sun damage
