Associations of mortality and cardiovascular disease risks with diabetes and albuminuria in urban Indigenous Australians: the DRUID follow-up study.

AIM: To assess the relationships of diabetes and albuminuria with all-cause mortality and cardiovascular disease outcomes in a population without prior cardiovascular disease using data from the Darwin Region Urban Indigenous Diabetes (DRUID) study. METHODS: We conducted a prospective cohort study of 706 participants (aged 15-81 years, 68% women) without prior cardiovascular disease who underwent a 75-g oral glucose tolerance test. Deaths and fatal or non-fatal cardiovascular disease were determined over 7 years, and hazard ratios with 95% CIs and population attributable risks were estimated for baseline glycaemia and albuminuria. RESULTS: Compared with normoglycaemia and after adjustment for age, sex, hypertension, dyslipidaemia and smoking, known diabetes was associated with an adjusted hazard ratio of 4.8 (95% CI 1.5-14.7) for all-cause mortality and 5.6 (95% CI 2.1-15.2) for cardiovascular disease. Compared with normoalbuminuria, the respective adjusted risks for macroalbuminuria were 10.9 (95% CI 3.7-32.1) and 3.9 (95% CI 1.4-10.8). The Adjusted all-cause mortality and cardiovascular disease estimated population attributable risks for diabetes were 27% and 32%, and for albuminuria they were 32% and 21%, respectively. CONCLUSIONS: In our study population, the burden of mortality and cardiovascular disease was largely driven by diabetes and albuminuria. This finding on the influence of diabetes and albuminuria is consistent with reports in other high-risk Indigenous populations and should be better reflected in risk scores and intervention programmes.

Polycystic ovary syndrome and metabolic syndrome in Indigenous Australian women.

BACKGROUND: Polycystic ovary syndrome (PCOS) affects around 15% of Indigenous women who are also a group at high risk of cardiometabolic disease. AIM: To explore the impact of PCOS on metabolic syndrome in Indigenous women. METHODS: A cross-sectional reproductive health questionnaire, biochemical and anthropometric assessments, of 109 Indigenous women (35 with PCOS and 74 without PCOS) aged 15-44 years in and around Darwin between 2003 and 2005. PCOS was defined using the National Institutes of Health criteria, and metabolic syndrome (MetS) using the National Cholesterol Education Programme Adult Treatment Programme III criteria. The outcome was prevalence of MetS by PCOS status; relationship of PCOS with MetS before and after adjustment for markers of obesity and insulin resistance. RESULTS: Women with PCOS had a significantly higher body mass index (BMI) (P = 0.0001) and MetS was more frequent in women with PCOS (51%) than those without PCOS (23%) (P = 0.003). The most frequent components of MetS in both groups were a high density lipoprotein cholesterol ≤1.29 mmol/L (80% PCOS, 55% non-PCOS) and a waist circumference >88 cm (77% PCOS, 41% non-PCOS); these were significantly more frequent in women with PCOS (P = 0.01). In logistic regression models, PCOS was significantly associated with MetS by itself but not after adjustment for BMI or sex hormone binding globulin. CONCLUSIONS: While MetS was more common in Indigenous women with PCOS, PCOS was not an independent predictor of MetS. This may be because obesity and insulin resistance are integral parts of PCOS and are the mechanisms through which PCOS exerts metabolic effects.

Effect of a Coaching Intervention to Improve Cardiologist Communication: A Randomized Clinical Trial.

Importance: Communication between cardiologists and patients can significantly affect patient comprehension, adherence, and satisfaction. To our knowledge, a coaching intervention to improve cardiologist communication has not been tested. Objective: To evaluate the effect of a communication coaching intervention to teach evidence-based communication skills to cardiologists. Design, Setting, and Participants: This 2-arm randomized clinical trial was performed at outpatient cardiology clinics at an academic medical center and affiliated community clinics, and from February 2019 through March 2020 recruited 40 cardiologists and audio recorded 161 patients in the preintervention phase and 240 in the postintervention phase. Data analysis was performed from March 2022 to January 2023. Interventions: Half of the cardiologists were randomized to receive a coaching intervention that involved three 1:1 sessions, 2 of which included feedback on their audio-recorded encounters. Communication coaches taught 5 skills derived from motivational interviewing: (1) sitting down and making eye contact with all in the room, (2) open-ended questions, (3) reflective statements, (4) empathic statements, and (5) "What questions do you have?" Main Outcomes and Measures: Coders unaware of study arm coded these behaviors in the preintervention and postintervention audio-recorded encounters (objective communication). Patients completed a survey after the visit to report perceptions of communication quality (subjective communication). Results: Analysis included 40 cardiologists (mean [SD] age, 47 [9] years; 7 female and 33 male) and 240 patients in the postintervention phase (mean [SD] age, 58 [15] years; 122 female, 118 male). When controlling for preintervention behaviors, cardiologists in the intervention vs control arm were more likely to make empathic statements (intervention: 52 of 117 [44%] vs control: 31 of 113 [27%]; P = .05); to ask, "What questions do you have?" (26 of 117 [22%] vs 6 of 113 [5%]; P = .002); and to respond with empathy when patients expressed negative emotions (mean ratio of empathic responses to empathic opportunities, 0.50 vs 0.20; P = .004). These effects did not vary based on patient or cardiologist race or sex. We found no arm differences for open-ended questions or reflective statements and were unable to assess differences in patient ratings due to ceiling effects. Conclusions and Relevance: In this randomized clinical trial, a communication coaching intervention improved 2 key communication behaviors: expressing empathy and eliciting questions. Empathic communication is a harder-level skill that may improve the patient experience and information comprehension. Future work should explore how best to assess the effect of communication coaching on patient perceptions of care and clinical outcomes and determine its effectiveness in larger, more diverse samples of cardiologists.

Clinician Perspectives on Managing Chronic Pain After Curative-Intent Cancer Treatment.

PURPOSE: Among cancer survivors who have completed curative-intent treatment, the high prevalence and adverse consequences of chronic pain are well documented. Yet, research on clinicians' experiences with and perspectives on managing chronic pain among cancer survivors is critically lacking. METHODS: We conducted semistructured interviews with 17 clinicians (six oncology, three palliative care, and eight primary care) affiliated with an academic medical center. Interview questions addressed clinicians' experiences with and perspectives on managing chronic pain (with or without opioid therapy) during the transition from active treatment to survivorship. A multidisciplinary team conducted content analysis of interview transcripts to identify and refine themes related to current practices and challenges in managing chronic pain in this context. RESULTS: Overall, clinicians perceived chronic pain to be relatively uncommon among cancer survivors. Identified challenges included a lack of clarity about which clinician (or clinicians) are best positioned to manage chronic pain among cancer survivors, and (relatedly) complexities introduced by long-term opioid management, with many clinicians describing this practice as outside their skill set. Additionally, although most clinicians recognized chronic pain as a biopsychosocial phenomenon, they described challenges with effectively managing psychosocial stressors, including difficulty accessing mental or behavioral health services for cancer survivors. CONCLUSION: Discovered challenges highlight unmet needs related to cancer survivor-clinician communication about chronic pain and the absence of a chronic pain management home for cancer survivors, including those requiring long-term opioid therapy. Research evaluating routine pain monitoring and accessible, tailored models of multimodal pain care in survivorship may help to address these challenges.

Calixarene monolayers as quartz crystal microbalance sensing elements in aqueous solution.

We have examined p-tert-butylcalix[4]arenetetrathiolate (BCAT) monolayers for their potential use as molecular recognition elements for in situ aqueous chemical sensors. Spectroscopic and wetting studies of BCAT monolayers on Au{111} reveal that the calixarene molecules exist in monolayers, preferentially oriented with their phenyl rings parallel to the surface normal axis. Using quartz crystal microbalance (QCM) sensors with gold-coated electrodes, the chemical specificity of monolayers and thin films to a variety of aromatic and aliphatic analytes in aqueous solution was examined. The response of BCAT sensors was compared to the responses of p-tert-butylcalix[4]arene (BCA)- and decanethiolate (DT)-coated QCM electrodes. BCAT is very selective for alkylbenzenes, much more so than either its spray-coated thin-film analogue, BCA, or the highly ordered DT monolayer. From these measurements, the factors behind molecular differentiation in each film are explored. Drawing upon these findings, the roles of cavitation and film order in molecular recognition for calixarene films are discussed.
