RESUMEN

BACKGROUND: Mobile clinics have been implemented in diverse clinical and geographical settings to provide proximal health care for specific populations. Primary health care mobile clinics have been implemented widely for Indigenous populations, with a paucity of research evaluations around service delivery models internationally. To redress factors impeding service accessibility for Aboriginal and Torres Strait Islander Peoples, Budja Budja Aboriginal Cooperative (Aboriginal Community Controlled Health Organisation located in a small rural town in Victoria, Australia), developed and implemented the Tulku wan Wininn primary health mobile clinic. METHODS: A qualitative process evaluation methodology was used to explore contextual factors mediating the implementation of the mobile clinic, including the acceptability of the service to health service personnel, external key informants, and Aboriginal and/or Torres Strait Islander clients. A synthesis of international ethical guidelines, (Consolidated Criteria for strengthening reporting of health research involving Indigenous peoples (CONSIDER statement), was prospectively applied to shape the study design and research process. Semi-structured interviews were conducted with participants. Data collection occurred from July 2019 to October 2021. Inductive thematic data analysis was undertaken concurrently with data collection. RESULTS: Data was collected from 19 participants which included 12 health service personnel and key informants, and 7 Aboriginal clients. In total, data from 22 interviews were included as interviews with three clients were undertaken twice. Four themes were developed: considerations for early implementation, maintaining face-to-face services during COVID-19, acceptability as a model of service delivery, and maintaining the mobile clinic as a service delivery model. CONCLUSION: Evidence supporting the acceptability of a primary health care mobile clinic for Aboriginal Peoples residing in rural Victoria is provided. Despite the experience of early implementation challenges and adaptations, the mobile clinic addressed known transport and cultural barriers to accessing primary health care services. In the context of COVID-19 lockdowns, the mobile clinic was valued for the provision of face-to-face care for Aboriginal clients. Key issues for maintaining the mobile clinic include health workforce and funding. Findings are of value to other organizations seeking to implement a primary health mobile clinic service delivery model to redress barriers to accessibility experienced by the communities they serve.

RESUMEN

BACKGROUND: Delivery of cardiovascular disease (CVD) prevention programs by community pharmacists appears effective and enhances health service access. However, their capacity to implement complex behavioural change processes during patient counselling remains largely unexplored. This study aims to determine intervention fidelity by pharmacists for behavioural components of a complex educational intervention for CVD prevention. After receiving training to improve lifestyle and medicines adherence, pharmacists recruited 70 patients aged 50-74 years without established CVD, and taking antihypertensive or lipid lowering therapy. Patients received five counselling sessions, each at monthly intervals. Researchers assessed biomedical and behavioural risk factors at baseline and six months. Pharmacists documented key outcomes from counselling after each session. Most patients (86%) reported suboptimal cardiovascular diets, 41% reported suboptimal medicines adherence, and 39% were physically inactive. Of those advised to complete the intervention, 85% attended all five sessions. Pharmacists achieved patient agreement with most recommended goals for behaviour change, and overwhelmingly translated goals into practical behavioural strategies. Barriers to changing behaviours were regularly documented, and pharmacists reported most behavioural strategies as having had some success. Meaningful improvements to health behaviours were observed post-intervention. Findings support further exploration of pharmacists' potential roles for delivering interventions with complex behaviour change requirements.

RESUMEN

This article reports on a project that aimed to discover whether rural placement can influence new graduates to take up rural positions, and what factors play a role in the decision-making. This pilot study reports the findings from a pre-survey of students (n = 110) who completed a questionnaire at the end of their rural placement in the Greater Green Triangle region, Australia. Findings are compared with matched questionnaire responses for students who subsequently completed a post-survey after graduation and who commenced work (n = 28). Rural placement appears to be associated with commencing rural practice after graduation. More graduates with an urban home address commenced rural practice than graduates with a rural home address who started their careers in the city. Longer placements may sway those with a city background to start work in a rural area.

RESUMEN

This paper describes the synthesis and characterization of micrometric phospholipid-coated polystyrene particles, named lipobeads, with pH-sensing capability and their application for intracellular pH measurements in murine macrophages. The phospholipids used to coat the particles are labeled with fluorescein (a pH-sensitive dye) and tetramethylrhodamine (a pH-insensitive dye), which serves as a referencing fluorophore for increased accuracy of the pH measurements. The synthesis of the pH-sensing lipobeads is realized by the covalent attachment of the fluorescent phospholipids to the surface of carboxylated polystyrene particles. The pH dynamic range of the sensing particles is between 5.5 and 7.0 with a sensitivity of 0.1 pH unit. The excitation light intensity is reduced to minimize photobleaching of the fluorescein-phospholipid conjugates. The fluorescent lipobeads are used to measure the pH in single macrophages. The lipobeads are ingested by the macrophages and directed to lysosomes, which are the cellular organelles involved in the phagocytosis process. Despite the high lysosomal levels of digestive enzymes and acidity, the absorbed particles remain stable for over 6 h in the cells when they are stored in a phosphate-buffered saline solution at pH 7.4.

RESUMEN

We report on far-field fluorescence imaging of single molecules in spherical polymer microparticles produced from solution by using microdroplet techniques. The fluorescence photobleaching quantum yields of rhodamine 6G in a common water-soluble polymer (polyvinyl alcohol) are at least five times smaller, corresponding to proportionally larger average fluorescence signals, than those in ethanolic solvents. This allows for acquisition of multiple images from a single molecule on a time scale of several minutes. We also show that fluorescent images of single molecules in microspheres can be calculated from semiclassic electrodynamics, which may ultimately be useful in retrieving dynamical information from experimental images.
