Enhancing early career professionals' representation and engagement at international conferences: WONCA "Rural Early Career Ambassador Integration" project.

INTRODUCTION: International conferences offer an excellent opportunity for career development and are global academic opportunities with the potential to foster educational and professional growth. However, equitable access to participation and meaningful involvement in such events remains an issue. In this article we describe the novel Rural Early Career Ambassador Integration project and its implications for the 2022 World Rural Health Conference, held at the University of Limerick, Ireland. METHODS: The project offered vertical and cross-country collaborative opportunities to early career professionals with a passion for rural medicine. Three ambassadors of diverse nationalities, ethnicities and professional backgrounds were selected. They bore no personal cost for travel, transport or accommodation relating to the conference. Each ambassador was matched to and clinically shadowed an expert rural GP for a week preceding the conference, who provided mentorship. Mentors and ambassadors collaborated on goal-setting and work-planning throughout the conference, and were offered one-on-one career and networking support. The ambassadors were welcomed and integrated within a larger working party, the WONCA Working Party for Rural Health. RESULTS: The project was well received by conference delegates and organisers, and achieved its stated goal of enhancing conference equity through the representation and meaningful involvement of diverse early career professionals. Vertical and cross-country collaboration generated actionable policy implications as is evidenced by the ambassadors' co-authorship on the Limerick Declaration on Rural Healthcare. CONCLUSION: Although sponsorship for these initiatives remains a challenge, this project highlights the importance of actively including early career professionals at international conferences.

The Limerick Declaration on Rural Health Care 2022.

The 19th World Rural Health Conference, hosted in rural Ireland and the University of Limerick, with over 650 participants coming from 40 countries and an additional 1600 engaging online, has carefully considered how best rural communities can be empowered to improve their own health and the health of those around them. The conference also considered the role of national health systems and all stakeholders, in keeping with the commitments made through the Sustainable Development Goals and the enjoyment of the highest attainable standard of health as one of the fundamental rights of every human being. This conference declaration, the Limerick Declaration on Rural Healthcare, is designed to inform rural communities, academics and policymakers about how to achieve the goal of delivering high quality health care in rural and remote areas most effectively, with a particular focus on the Irish healthcare system. Congruent with current evidence and best international practice, the participants of the conference endorsed a series of recommendations for the creation of high quality, sustainable and cost-effective healthcare delivery for rural communities in Ireland and globally. The recommendations focused on four major themes: rural healthcare needs and delivery, rural workforce, advocacy and policy, and research for rural health care. Equal access to health care is a crucial marker of democracy. Hence, we call on all governments, policymakers, academic institutions and communities globally to commit to providing their rural dwellers with equitable access to health care that is properly resourced and fundamentally patient-centred in its design.

Comparative pulmonary toxicities of lunar dusts and terrestrial dusts (TiO2 & SiO2) in rats and an assessment of the impact of particle-generated oxidants on the dusts' toxicities.

Humans will set foot on the Moon again soon. The lunar dust (LD) is potentially reactive and could pose an inhalation hazard to lunar explorers. We elucidated LD toxicity and investigated the toxicological impact of particle surface reactivity (SR) using three LDs, quartz, and TiO2. We first isolated the respirable-size-fraction of an Apollo-14 regolith and ground two coarser samples to produce fine LDs with increased SR. SR measurements of these five respirable-sized dusts, determined by their in-vitro ability to generate hydroxyl radicals (•OH), showed that ground LDs > unground LD ≥ TiO2 ≥ quartz. Rats were each intratracheally instilled with 0, 1, 2.5, or 7.5 mg of a test dust. Toxicity biomarkers and histopathology were assessed up to 13 weeks after the bolus instillation. All dusts caused dose-dependent-increases in pulmonary lesions and toxicity biomarkers. The three LDs, which possessed mineral compositions/properties similar to Arizona volcanic ash, were moderately toxic. Despite a 14-fold •OH difference among these three LDs, their toxicities were indistinguishable. Quartz produced the lowest •OH amount but showed the greatest toxicity. Our results showed no correlation between the toxicity of mineral dusts and their ability to generate free radicals. We also showed that the amounts of oxidants per neutrophil increased with doses, time and the cytotoxicity of the dusts in the lung, which supports our postulation that dust-elicited neutrophilia is the major persistent source of oxidative stress. These results and the discussion of the crucial roles of the short-lived, continuously replenished neutrophils in dust-induced pathogenesis are presented.

The impact of value-based benefit design on adherence to diabetes medications: a propensity score-weighted difference in difference evaluation.

OBJECTIVE: To evaluate the impact of value-based benefit design (VBBD) on adherence to diabetes medications. METHODS: Health Alliance Medical Plans piloted VBBD for diabetes medications for a subgroup of 5400 enrollees in January 2007 while keeping drug benefits unchanged for the remaining plan enrollees. A difference in difference method (DID) was used to evaluate the effect of VBBD based on pharmacy claim data. Patients with unchanged benefits in the same plan were used as the control group. Adherence was measured by the proportion of days covered. Propensity score weighting was used to balance characteristics of the case group and the control group. RESULTS: There were 71 patients in the case group and 5037 patients in the control group. The patients in the two groups had comparable characteristics after propensity score weighting. After the implementation of VBBD, the average copayment per 30 days of supply for diabetes medications decreased from $15.3 to $10.1 for the case group and increased from $14.6 to $15.1 for the control group. The probability of being adherent increased from 75.3% to 82.6% for the case group and was roughly unchanged from 79.1% to 78.5% for the control group. Propensity score-weighted DID analysis showed that patients with copayment reduction had greater odds of being adherent: odds ratio=1.56, P=0.03, 95% confidence interval 1.04-2.34. CONCLUSION: A VBBD program that reduced the copayment for diabetes medications by 36.1% reduced the number of nonadherent patients by 30.0%.
