Partner-Involved Financial Incentives for Smoking Cessation in Dual-Smoker Couples: A Randomized Pilot Trial.

INTRODUCTION: Members of dual-smoker couples (in which both partners smoke) are unlikely to try to quit smoking and are likely to relapse if they do make an attempt. The purpose of this study was to investigate the feasibility, tolerability, and preliminary outcomes of dyadic adaptations of financial incentive treatments (FITs) to promote smoking cessation in dual-smoker couples. AIMS AND METHODS: We enrolled 95 dual-smoker couples (N = 190) in a three-arm feasibility RCT comparing two partner-involved FITs (single vs. dual incentives) against a no-treatment control condition. Participants in all conditions were offered nicotine replacement and psychoeducation. A 3-month follow-up provided information about retention, tolerability (ie, self-reported benefits and costs of the study), and preliminary efficacy (ie, program completion, quit attempts, point-prevalent abstinence, and joint quitting). RESULTS: Results suggest dyadic adaptations were feasible to implement (89% retention rate) and highly tolerable for participants (p < .001). Neither feasibility nor tolerability varied across the treatment arm. Preliminary efficacy outcomes indicated partner-involved FITs have promise for increasing smoking cessation in dual-smoker couples (OR = 2.36-13.06). CONCLUSIONS: Dyadic implementations of FITs are feasible to implement and tolerable to participants. IMPLICATIONS: The evidence that dyadic adaptations of FITs were feasible and tolerable, and the positive preliminary efficacy outcomes suggest that adequately powered RCTs formally evaluating the efficacy of dyadic adaptations of FITs for dual-smoker couples are warranted.

Assessing medical student satisfaction with rural placement: The Australian Rural Clinical School Support Survey.

INTRODUCTION: Australia has a doctor shortage in rural settings, and rural placements for medical students have an important role in increasing the likelihood of students staying in rural settings throughout their careers. However, to date there is limited research regarding medical student perceptions of rural placement quality. OBJECTIVE: We aimed to determine factors that impact the overall medical student experience during rural placements. DESIGN: Cross-sectional survey. SETTING: Rural/remote clinical schools across Australia. PARTICIPANTS: Medical students on rural/remote clinical placements for at least 6 months. MAIN OUTCOME MEASURES: To assess factors impacting student experience on rural placements, we conducted a cross-sectional survey, known as the Australian Rural Clinical School Support Survey (ARCSSS) which was completed online by medical students across Australia. Demographic data were collected in addition to responses regarding academic teaching, extracurricular activities, and support services. Multiple choice and Likert scale questions were utilised. RESULTS: A total of 107 responses to our survey were analysed. The majority of participants were female (66.4%), and in their middle years of clinical education (55.1%). Overall, respondents showed high levels of satisfaction with clinical school supervisors, and clinical education. A high proportion of respondents indicated minimal accessibility of health and other support services. While a large proportion of participants indicated satisfaction with the rural placements, it was demonstrated that students were generally dissatisfied with school wellness activities and extracurricular activities. Financial insecurity was noted. CONCLUSION: The findings from our survey indicate there are numerous areas in which rural placements have been effective for medical students, and others in which improvement is needed. Furthermore, more research is required to better develop well-being initiatives that are effective in improving overall experience.

Influence of rural clinical school experience and rural origin on practising in rural communities five and eight years after graduation.

OBJECTIVE: To examine associations between extended medical graduates' rural clinical school (RCS) experience and geographic origins with practising in rural communities five and eight years after graduation. DESIGN, PARTICIPANTS: Cohort study of 2011 domestic medical graduates from ten Australian medical schools with rural clinical or regional medical schools. MAIN OUTCOME MEASURES: Practice location types eight years after graduation (2019/2020) as recorded by the Australian Health Practitioner Regulation Agency, classified as rural or metropolitan according to the 2015 Modified Monash Model; changes in practice location type between postgraduate years 5 (2016/2017) and 8 (2019/2020). RESULTS: Data were available for 1321 graduates from ten universities; 696 were women (52.7%), 259 had rural backgrounds (19.6%), and 413 had extended RCS experience (31.3%). Eight years after graduation, rural origin graduates with extended RCS experience were more likely than metropolitan origin graduates without this experience to practise in regional (relative risk [RR], 3.6; 95% CI, 1.8-7.1) or rural communities (RR, 4.8; 95% CI, 3.1-7.5). Concordance of location type five and eight years after graduation was 92.6% for metropolitan practice (84 of 1136 graduates had moved to regional/rural practice, 7.4%), 26% for regional practice (56 of 95 had moved to metropolitan practice, 59%), and 73% for rural practice (20 of 100 had moved to metropolitan practice, 20%). Metropolitan origin graduates with extended RCS experience were more likely than those without it to remain in rural practice (RR, 2.0; 95% CI, 1.3-2.9) or to move to rural practice (RR, 1.9; 95% CI, 1.2-3.1). CONCLUSION: The distribution of graduates by practice location type was similar five and eight years after graduation. Recruitment to and retention in rural practice were higher among graduates with extended RCS experience. Our findings reinforce the importance of longitudinal rural and regional training pathways, and the role of RCSs, regional training hubs, and the rural generalist training program in coordinating these initiatives.

Growing the pool of rural general practitioners.

The critical importance of primary health care in maintaining a healthy population is well established internationally. Nevertheless, general practitioner care is not always easily accessible for some patients in Australia, particularly in rural regions. This is partly due to an insufficient number of medical graduates entering and being retained in the rural general practitioner workforce. Key elements of international and national programs designed to address this shortfall are discussed and include the use of entry requirements that preferentially select for applicants from a rural residence background, and immersion of medical students for a large share, or entire duration, of their training in rural communities. In addition, other factors that can influence decisions to enter and stay in rural practice are discussed.

Cardiac structure and function after revascularization versus medical therapy for renal artery stenosis: the ASTRAL heart echocardiographic sub-study.

BACKGROUND: The ASTRAL trial showed no difference in clinical outcomes between medical therapy and revascularization for atherosclerotic renal vascular disease (ARVD). Here we report a sub-study using echocardiography to assess differences in cardiac structure and function at 12 months. METHODS: ASTRAL patients from 7 participating centres underwent echocardiography at baseline and 12 months after randomisation. Changes in left ventricular ejection fraction (LVEF), left ventricular mass (LVM), left atrial diameter (LAD), aortic root diameter (AoRD), E:A, and E deceleration time (EDT) were compared between study arms. Analyses were performed using t-tests and multivariate linear regression. RESULTS: Ninety two patients were included (50 medical versus 42 revascularization). There was no difference between arms in any baseline echocardiographic parameter. Comparisons of longitudinal changes in echocardiographic measurements were: δLVEF medical 0.8 ± 8.7% versus revascularization - 2.8 ± 6.8% (p = 0.05), δLVM - 2.9 ± 33 versus - 1.7 ± 39 g (p = 0.9), δLAD 0.1 ± 0.4 versus 0.01 ± 0.5 cm (p = 0.3), δAoRD 0.002 ± 0.3 versus 0.06 ± 0.3 cm (p = 0.4), δE:A - 0.0005 ± 0.6 versus 0.03 ± 0.7 (p = 0.8), δEDT - 1.1 ± 55.5 versus - 9.0 ± 70.2 ms (p = 0.6). In multivariate models, there were no differences between treatment groups for any parameter at 12 months. Likewise, change in blood pressure did not differ between arms (mean δsystolic blood pressure medical 0 mmHg [range - 56 to + 54], revascularization - 3 mmHg [- 61 to + 59], p = 0.60). CONCLUSIONS: This sub-study did not show any significant differences in cardiac structure and function accompanying renal revascularization in ASTRAL. Limitations include the small sample size, the relative insensitivity of echocardiography, and the fact that a large proportion of ASTRAL patient population had only modest renal artery stenosis as described in the main study.

The Australian Rural Clinical School (RCS) program supports rural medical workforce: evidence from a cross-sectional study of 12 RCSs.

INTRODUCTION: Many strategies have been implemented to address the shortage of medical practitioners in rural areas. One such strategy, the Rural Clinical School Program supporting 18 rural clinical schools (RCSs), represents a substantial financial investment by the Australian Government. This is the first collaborative RCS study summarising the rural work outcomes of multiple RCSs. The aim of this study was to combine data from all RCSs' 2011 graduating classes to determine the association between rural location of practice in 2017 and (i) extended rural clinical placement during medical school (at least 12 months training in a rural area) and (ii) having a rural background. METHODS: All medical schools funded under the RCS Program were contacted by email about participation in this study. De-identified data were supplied for domestic students about their gender, origin (rural background defined as having lived in an Australian Standard Geographic Classification-Remoteness Area (ASGC-RA) 2-5 area for at least 5 years since beginning primary school) and participation in extended rural clinical placement (attended an RCS for at least 1 year of their clinical training). The postcode of their practice location according to the publicly available Australian Health Practitioner Regulation Agency (AHPRA) register was collected (February to August 2017) and classified into rural and metropolitan areas using the ASGC 2006 and the more recent Modified Monash Model (MMM). The main outcome measure was whether graduates were working in a 'rural' area (ASGC categories RA2-5 or MMM categories 3-7) or 'metropolitan' area. Pearson's χ2 test was used to detect differences in gender, rural background and extended placement at an RCS between rural and metropolitan practice locations. Binary logistic regression was used to determine odds of rural practice and 95% confidence intervals (CIs) were calculated. RESULTS: Although data were received from 14 universities, two universities had not started collecting origin data at this point so were excluded from the analysis. The proportion of students with a rural background had a range of 12.3-76.6% and the proportion who had participated in extended RCS placement had a range of 13.7-74.6%. Almost 17% (16.6%) had a principal practice postcode in a rural area (according to ASGC), range 5.8-55.6%, and 8.3% had a principal practice postcode in rural areas (according to MMM 3-7), range 4.5-29.9%. After controlling for rural background, it was found that students who attended an RCS were 1.5 times more likely to be in rural practice (95%CI 1.2-2.1, p=0.004) using ASGC criteria. Using the MMM 3-7 criteria, students who participated in extended RCS placement were 2.6 times as likely to be practising in a rural location (95%CI 1.8-3.8, p<0.001) after controlling for rural background. Regardless of geographic classification system (ASGC, MMM) used for location of practice and of student background (metropolitan or rural), those students with an extended RCS had an increased chance of working rurally. CONCLUSION: Based on the combined data from three-quarters (12/16) of the Australian medical schools who had a graduating class in 2011, this suggests that the RCS initiative as a whole is having a significant positive effect on the regional medical workforce at 5 years post-graduation.

Effect of renal artery revascularization upon cardiac structure and function in atherosclerotic renal artery stenosis: cardiac magnetic resonance sub-study of the ASTRAL trial.

BACKGROUND: Cardiac abnormalities are frequent in patients with atherosclerotic renovascular disease (ARVD). The Angioplasty and Stenting for Renal Artery Lesions (ASTRAL) trial studied the effect of percutaneous renal revascularization combined with medical therapy compared with medical therapy alone in 806 patients with ARVD. METHODS: This was a pre-specified sub-study of ASTRAL (clinical trials registration, current controlled trials number: ISRCTN59586944), designed to consider the effect of percutaneous renal artery angioplasty and stenting on change in cardiac structure and function, measured using cardiac magnetic resonance (CMR) imaging. Fifty-one patients were recruited from six selected ASTRAL centres. Forty-four completed the study (medical therapy n = 21; revascularization n = 23). Full analysis of CMR was possible in 40 patients (18 medical therapy and 22 revascularization). CMR measurements of left and right ventricular end systolic (LV and RVESV) and diastolic volume (LV and RVEDV), ejection fraction (LVEF) and mass (LVM) were made shortly after recruitment and before revascularization in the interventional group, and again after 12 months. Reporting was performed by CMR analysts blinded to randomization arm. RESULTS: Groups were well matched for mean age (70 versus 72 years), blood pressure (148/71 versus 143/74 mmHg), degree of renal artery stenosis (75 versus 75%) and comorbid conditions. In both randomized groups, improvements in cardiac structural parameters were seen at 12 months, but there were no significant differences between treatment groups. Median left ventricular changes between baseline and 12 months (medical versus revascularization) were LVEDV -1.9 versus -5.8 mL, P = 0.4; LVESV -2.1 versus 0.3 mL, P = 0.7; LVM -5.4 versus -6.3 g, P = 0.8; and LVEF -1.5 versus -0.8%, P = 0.7. Multivariate regression also found that randomized treatment assignment was not associated with degree of change in any of the CMR measurements. CONCLUSIONS: In this sub-study of the ASTRAL trial, renal revascularization did not offer additional benefit to cardiac structure or function in unselected patients with ARVD.

Comparing a longitudinal integrated clerkship with traditional hospital-based rotations in a rural setting.

CONTEXT: Longitudinal integrated clerkships (LIC) are widely used as an educational method, particularly in rural areas. They are good for facilitating hands-on learning and deep relationships between student, patients, and supervisors. OBJECTIVES: This study sought to examine and compare learning experience of third-year rural medical students studying specialties (women's health, aged care, child and adolescent heath, mental health, general practice) by either a traditional hospital-based rotation or a LIC in a rural general practice setting. METHODS: Data was collected from two groups of rural students (LIC; traditional hospital-based) over two academic years, utilizing focus groups to investigate general experiences of living and learning rurally, within the different educational models. RESULTS: Results reaffirmed that there was no perceived academic disadvantage to studying medicine rurally. Studying medicine in a rural area provides increased access to patients, more hands-on experience, and close relationships with patients and colleagues. LIC students reported increased confidence in clinical skills, felt better prepared for internship, however experienced more social isolation than students in hospital-based rotations. CONCLUSIONS: Students undergoing a rural LIC feel more confident in their clinical skills and preparedness for practice than other rural students. This study supports the use of LICs as a powerful educational tool.

Barriers to effective conversations regarding overweight and obesity in regional Victoria.

BACKGROUND: General practitioners (GPs) have a crucial role to play in engaging patients in discussions about overweight and obesity. However, such discussions are currently uncommon. The aim of this study was to examine how GPs in rural areas talk about overweight and obesity with their patients, specifically to identify key barriers to effective conversations. METHODS: This study used a qualitative methodology. Semi-structured interviews were conducted with GPs (n = 7) and patients (n = 7) across two rural areas. RESULTS: Key barriers to effective conversations between GPs and patients about overweight and/or obesity include: uncertainty about appropriate language; lack of time; concerns about compromising mutual trust and rapport; concerns about patient readiness; concerns about patients' mental health and how this may be impacted by discussing a potentially upsetting and stigmatising topic; and lack of effective and individualised treatment and/or referral options. DISCUSSION: The findings suggest that responses to overweight and obesity need to be localised and tailored. Structural-level change is required to enable better responses to overweight and obesity, including multidisciplinary team approaches.

Integrated and consumer-directed care: a necessary paradigm shift for rural chronic ill health.

Chronic ill health has recently emerged as the most important health issue on a global scale. Rural communities are disproportionally affected by chronic ill health. Many health systems are centred on the management of acute conditions and are often poorly equipped to deal with chronic ill health. Cardiovascular disease (CVD) is one of the most prominent chronic ill health conditions and the principal cause of mortality worldwide. In this paper, CVD is used as an example to demonstrate the disparity between rural and urban experience of chronic ill health, access to medical care and clinical outcomes. Advances have been made to address chronic ill health through improving self-management strategies, health literacy and access to medical services. However, given the higher incidence of chronic health conditions and poorer clinical outcomes in rural communities, it is imperative that integrated health care emphasises greater collaboration between services. It is also vital that rural GPs are better supported to work with their patients, and that they use consumer-directed approaches to empower patients to direct and coordinate their own care.

A short-term rural placement can change metropolitan medical students' knowledge of, and attitudes to, rural practice.

OBJECTIVE: To determine whether a short-term placement of metropolitan medical students in a rural environment can improve their knowledge of, and change their attitudes to, rural health issues. DESIGN AND PARTICIPANTS: Medical students taking part in the March and May 2013 3-week Rural Health Modules (RHMs) were invited to participate in focus groups and complete questionnaires before undertaking the RHM, after a 2-day rural orientation and at the end of the RHM. Students were asked to comment on a range of issues affecting rural health care including their attitude to pursuing a rural career. Focus group transcripts were thematically analysed and questionnaire data were statistically analysed. SETTING: The RHM is a 3-week program designed and run by the University of Melbourne's Rural Health Academic Centre. MAIN OUTCOME MEASURES: Responses to questionnaire items from before and after completing the RHM, scored on a seven-point Likert scale. RESULTS: 69 of the 101 RHM students took part in this study. The focus groups identified five main themes in rural health care: access; teamwork, models of care and generalist practice; overlapping relationships; indigenous health; and working in a rural career. In all five areas, a change was seen in the depth of knowledge students had about these issues and in the students' attitudes towards rural health care. The questionnaires also showed a significant shift in the students' appreciation of, and positivity towards, rural health issues. CONCLUSION: Undertaking a 3-week RHM changed students' perceptions of rural health and significantly improved their knowledge of issues facing rural health practitioners and patients.

Mentoring as a retention strategy to sustain the rural and remote health workforce.

OBJECTIVE: To propose a model of mentoring suitable for rural and remote health professionals. DESIGN: Given the rural and remote health workforce shortage, mentoring is proposed as a workforce retention strategy. Mentoring literature was reviewed; aspects of mentoring highlighted in the literature were considered to ascertain their suitability for rural and remote health professionals. METHOD: A total of 39 mentoring papers were reviewed to outline key factors in mentoring rural and remote health professionals. Using this literature, key ways that rural and remote practice enhance or are barriers to mentoring were identified. From this, a model for mentoring rural and remote health practitioners, students and academics was developed. RESULTS: Four models of mentoring were identified: the cloning, nurturing, friendship and apprenticeship models. The apprenticeship model was identified as suitable for students, the nurturing model as suited to new health professionals to rural and remote settings and the friendship model for senior practitioners/academics. Factors more likely to enable mentoring in rural and remote settings were identified as feelings of obligation by senior practitioners, strong relationships between staff, blurred work/social boundaries, lack of hierarchy, inter-professional practice and technology. The barriers identified included workloads, access to mentors, fee-for-service system for some practitioners, conflicts which could jeopardise working and business relationships, and feelings of being judged. CONCLUSIONS: A model of mentoring for rural and remote health professionals was presented. Given the potential to strengthen and increase the rural and remote health workforce, trialling such a model is worthwhile and evaluation would identify its impact.

When What Is Beautiful Is Not Good: The Role of Trait Self-Control in Resisting Eye Candy.

People are drawn to and like others who are physically attractive. In the present research, we investigated the influence of trait self-control on individuals' interest in relationships with physically attractive others. We hypothesized that high (vs. low) self-control individuals would approach relationships by considering information beyond appearance about potential partners, including partners' self-control. We additionally explored the influence of other traits (e.g., Big 5, self-esteem, and attachment styles) on relationship interest. Across studies, we consistently found that individuals with higher self-control avoided pursuing relationships with attractive individuals who display low self-control. In Study 3, we observed a similar pattern for three other traits: conscientiousness, extraversion, and positivity embracement. These results suggest perceivers' self-control shapes relationship interest, particularly when attractive individuals possess less desirable qualities. The findings extend past research that attractiveness increases interest in others and highlights the potential for trait self-control to direct relationship interest during initial interactions.

Association between rural exposure/experience and practice location 10 years postgraduation, stratified by specialty: evidence from a cohort study of graduates from nine Australian universities.

OBJECTIVE: This study aims to determine the associations between specialty type and practice location at postgraduate year 10 (PGY10), matched with PGY5 and PGY8 work locations, and earlier rural exposure/experience. DESIGN AND SETTING: A cohort study of medicine graduates from nine Australian universities. PARTICIPANTS: 1220 domestic medicine graduates from the class of 2011. OUTCOME MEASURES: Practice location recorded by the Australian Health Practitioner Regulation Agency in PGY10; matched graduate movement between PGYs 5, 8 and 10 as classified by the Modified Monash Model, stratified by specialty type (predominantly grouped as general practitioner (GP) or non-GP). RESULTS: At PGY10, two-thirds (820/1220) had achieved fellowship. GPs were 2.8 times more likely to be in non-metropolitan practice (28% vs 12%; 95% CI 2.0 to 4.0, p<0.001) than graduates with non-GP (all other) specialist qualifications. More than 70% (71.4%) of GPs who were in non-metropolitan practice in PGY5 remained there in both PGY8 and PGY10 versus 29.0% of non-GP specialists and 36.4% of non-fellowed graduates (p<0.001). The proportion of fellowed graduates observed in non-metropolitan practice was 14.9% at PGY5, 16.1% at PGY8 and 19.0% at PGY10, with this growth predominantly from non-GP specialists moving into non-metropolitan locations, following completion of metropolitan-based vocational training. CONCLUSIONS: There are strong differences in practice location patterns between specialty types, with few non-GP specialists remaining in non-metropolitan practice between PGY5 and PGY10. Our study reinforces the importance of rural training pathways to longer-term work location outcomes and the need to expand specialist vocational training which supports more rural training opportunities for trainees outside general practice.

Palliative Approach Remains Lacking in Terminal Hospital Admissions for Chronic Disease Across Rural Settings: Multisite Retrospective Medical Record Audit.

INTRODUCTION/AIM: Despite clear benefit from palliative care in end-stage chronic diseases, access is often limited, and rural access largely undescribed. This study sought to determine if a palliative approach is provided to people with chronic disease in their terminal hospital admission. METHODS: Multisite, retrospective medical record audit, of decedents with a primary diagnosis of chronic lung, heart, or renal failure, or multimorbidity of these conditions over 2019. RESULTS: Of 241 decedents, across five clinical sites, 143 (59.3%) were men, with mean age 80.47 years (SD 11.509), and diagnoses of chronic lung (n = 56, 23.2%), heart (n = 56, 23.2%), renal (n = 24, 10.0%) or multimorbidity disease (n = 105, 43.6%), and had 2.88 (3.04SD) admissions within 12 months. Outpatient chronic disease care was evident (n = 171, 73.7%), however, contact with a private physician (n = 91, 37.8%), chronic disease program (n = 61, 25.3%), or specialist nurse (n = 17, 7.1%) were less apparent. "Not-for-resuscitation" orders were common (n = 139, 57.7%), however, advance care planning (n = 71, 29.5%), preferred place of death (n = 18, 7.9%), and spiritual support (n = 18, 7.5%) were rarely documented. Referral to and input from palliative services were low (n = 74, 30.7% and n = 49, 20.3%), as was review of nonessential medications or blood tests (n = 86, 35.7%, and n = 78, 32.4%). Opioids were prescribed in 45.2% (n = 109). Hospital site and diagnosis were significantly associated with outpatient care and palliative approach (P<0.001). CONCLUSIONS: End-of-life planning and specialist palliative care involvement occurred infrequently for people with chronic disease who died in rural hospitals. Targeted strategies are necessary to improve care for these prevalent and high needs rural populations.

Service Level Characteristics of Rural Palliative Care for People with Chronic Disease.

CONTEXT: Despite clear benefit from palliative care in end-stage chronic, non-malignant disease, access for rural patients is often limited due to workforce gaps and geographical barriers. OBJECTIVES: This study aimed to understand existing rural service structures regarding the availability and provision of palliative care for people with chronic conditions. METHODS: A cross-sectional online survey was distributed by email to rural health service leaders. Nominal and categorical data were analyzed descriptively, with free-text questions on barriers and facilitators in chronic disease analyzed using qualitative content analysis. RESULTS: Of 42 (61.7%) health services, most were public (88.1%) and operated in acute (19, 45.2%) or community (16, 38.1%) settings. A total of 17 (41.5%) reported an on-site specialist palliative care team, primarily nurses (19, 59.5%). Nearly all services (41, 95.3%) reported off-site specialist palliative care access, including: established external relationships (38, 92.7%); visiting consultancy (26, 63.4%); and telehealth (18, 43.9%). Perceived barriers in chronic disease included: lack of specific referral pathways (18; 62.1%); negative patient expectations (18; 62.1%); and availability of trained staff (17; 58.6%). Structures identified to support palliative care in chronic disease included: increased staff/funding (20, 75.0%); formalized referral pathways (n = 18, 64.3%); professional development (16, 57.1%); and community health promotion (14, 50%). CONCLUSION: Palliative care service structure and capacity varies across rural areas, and relies on a complex, at times ad hoc, network of onsite and external supports. Services for people with chronic, non-malignant disease are sparse and largely unknown, with a call for the development of specific referral pathways to improve patient care.

Designing clinical trials for future space missions as a pathway to changing how clinical trials are conducted on Earth.

OBJECTIVE: The project aims to build a framework for conducting clinical trials for long-term interplanetary missions to contribute to innovation in clinical trials on Earth, especially around patient involvement and ownership. METHODS: We conducted two workshops in which participants were immersed in the speculative scenario of an interplanetary mission in which health problems emerged that required medical trials to resolve. The workshops used virtual reality and live simulation to mimic a zero-gravity environment and visual perception shifts and were followed by group discussion. RESULTS: Some key aspects for the framework that emerged from the workshops included: (a) approaches to be inclusive in the management of the trial, (b) approaches to be inclusive in designing the research project (patient preference trials, n-of-1 trials, designing clinical trials to be part of a future prospective meta-analysis, etc), (c) balancing the research needs and the community needs (eg, allocation of the participants based on both research and community need), (d) ethics and partnerships (ethics and consent issues and how they relate to partnerships and relationships). CONCLUSION: In identifying some key areas that need to be incorporated in future planning of clinical trials for interplanetary missions, we also identified areas that are relevant to engaging patients in clinical trials on Earth. We will suggest using the same methodology to facilitate more in-depth discussions on specific aspects of clinical trials in aerospace medicine. The methodology can be more widely used in other areas to open new inclusive conversations around innovating research methodology.

Role of renal function and cardiac biomarkers (NT-proBNP and Troponin) in determining mortality and cardiac outcome in atheromatous renovascular disease.

BACKGROUND AND AIMS: Patients with atheromatous renovascular disease (ARVD) have high cardiovascular morbidity and mortality. The cardiac markers N-terminal pro-brain natriuretic peptide (NT-proBNP) and troponin (cTnT) are easily measured, yet not widely used in renal patients as they are thought to be inaccurate in renal disease. We aimed to see if these markers could be used as prognostic indicators of cardiovascular events (CVEs) and death in ARVD. METHODS: Subjects with ARVD treated in 1 renal center in 2003 were prospectively followed up. NT-proBNP and cTnT at baseline were correlated with CVEs and death, echocardiographic findings and degree of renal artery stenosis. Cutoff levels of 0.03 ng/ml (cTnT) and 43 pmol/l (NT-proBNP) were used. RESULTS: Eighty-two patients (mean +/- SD age 69 +/- 8 years, mean follow-up 40.2 +/- 16.6 months) were suitable for analysis. Twenty-nine percent of patients suffered new CVEs, and 37.8% died. Renal function was a significant predictor of CVEs and death. Patients with a raised NT-proBNP were more likely to die than those in the same chronic kidney disease (CKD) category with normal levels (p < 0.0001) even after adjusting for multivariate factors (hazard ratio 8.3 for high proBNP vs. 3.6 for low proBNP in CKD stage 4-5). CONCLUSION: No study to our knowledge has looked at both NT-proBNP and cTnT as outcome markers in ARVD. Our study shows that renal function is more important as a marker of suffering a CVE. However, raised NT-proBNP is associated with a greater likelihood of death when subdivided by CKD stage. Early risk stratification by simple measurement of these biomarkers may aid in intensifying management in high-risk patients, although further studies to assess the value of this approach are warranted.
