Objectives: With elimination of the financial burden of dental services, one can expect an increase in utilization of dental services. This study aimed to investigate the effective mechanisms of financial barriers to the utilization of dental services in an Australian adult population.
Methods: South Australian survey data from the Dental Care and Oral Health Study (2015) were analysed. Following the flexible mediation approach, the direct effect of income and indirect effect of income through mediators (insurance, concession card and service sector) on the outcomes (visit avoidance and treatment prevention due to the cost) were calculated.
Results: Findings showed that around half of the low-income people and one-third of the high-income South Australians experienced a financial burden on receiving a dental visit or service. The indirect effect of income on both outcomes of financial burden was negligible, while the direct effect was significant. By changing the potential outcome distribution to their counterfactual exposure distribution and if the mediators are drawn from their counterfactual exposure (lower/higher income) distribution, the odds of visit avoidance and treatment prevention due to the cost were almost twice (Odds Ratio: 2.13, 95% CI 1.72-2.60) and 98% (Odds Ratio: 1.98, 95% CI 1.67-2.35) than in the lower-income individuals, respectively.
Conclusions: It can be concluded that the level of household income, directly and regardless of insurance status, concession card ownership and whether the service sector was public or private, affected the financial burden on utilization of dental services.

Introduction: Obesity and its complications are associated with high morbidity/mortality and a significant healthcare cost burden in Spain. It is therefore essential to know the potential clinical and economic benefits of reducing obesity. The objective of this study is to predict the decrease in rates of onset of potential complications associated with obesity and the cost savings after a weight loss of 15% over 10 years in Spain.

Background: African Americans experience cardiovascular disease (CVD) disparities, and the burden is greatest in the rural south. Although evidence-based CVD prevention and management programs have been tailored to this context, implementation has been limited and not sustained long-term. To understand how to implement and sustain evidence-based CVD programs at scale, we must explore the perspectives of organizations serving rural African American communities and situate findings within foundational Implementation Science frameworks.

Although the FDA has recently indicated openness for non-abstinence outcomes as treatment targets, the traditional benchmark of complete abstinence for new medications to treat SUDs remains a hurdle and overshadows other non-abstinent outcomes desired by people with SUDs (e.g.

Background: Individuals with Sickle Cell Disease (SCD) are a minoritized and marginalized community that have disparate health outcomes as a result of systemic racism and disease-related stigma. The purpose of this study was to determine the psychosocial risk factors for families caring for children with SCD at a pediatric SCD center through use of the Psychosocial Assessment Tool (PAT), a validated caregiver-report screener.
Methods: The PAT was administered annually during routine clinical visits and scored by the SCD Social Worker to provide tailored resources to families.

Drought has a significant impact on ecosystem functions, especially on the biogeochemical cycling of phosphorus (P), which is a crucial nutrient for plant growth and productivity. Despite its importance, the effects of different drought scenarios on soil P cycling and availability remain poorly understood in previous studies. This study simulated drought conditions in tropical soils using maize as a test crop under varying field capacity (FC) levels (100%, 80%, 60%, 40%, and 20%) over a 60-day pot experiment.
