Urban populations are exposed to elevated local temperatures compared to surrounding rural areas due to the urban heat island (UHI) effect, which increases health risks and energy demand. The literature highlights that accurately quantifying UHIs at broader territorial scales remains challenging because of limited microscale climate data availability and, at the same time, the difficulty of increasing the spatial coverage of the outcomes. Within the PRIN2022-PNRR CRiStAll (Climate Resilient Strategies by Archetype-based Urban Energy Modeling) project, this work addresses these limitations by coupling Urban Building Energy Modeling with archetype-based representation of urban form and high-resolution climatic data. Urban archetypes are defined as representative microscale configurations derived from combinations of urban canyon geometries and building typologies, accounting for different climatic zones, use categories, and construction periods. The proposed methodology was applied to the city of Turin (Italy), where representative urban blocks were identified and modeled to evaluate key urban context metrics under short-, medium-, and long-term climate scenarios. The UHI effect was assessed using Urban Weather Generator, while energy simulations were performed with CitySim. The urban archetype approach enables both fine spatial resolution and extensive spatial coverage, supporting urban-scale mapping. Full article

Food-borne diseases affect nearly 10% of the global population annually, with Salmonella being a major cause, particularly impacting children, the elderly, and populations in low- and middle-income countries. This study aimed to assess the prevalence, serotype distribution, antibiotic resistance profiles, and genetic determinants of resistance and virulence of Salmonella enterica in humans and poultry in the Nanoro health district. A community-based cross-sectional study involving humans and poultry was conducted in the Nanoro health district. Fresh stool samples (human and poultry cloacal/cecal) were collected, transported under sterile conditions, and processed within two hours using standard bacteriological methods. Phenotypic antibiotic resistance was determined by the Kirby–Bauer disk diffusion method, and whole-genome sequencing (Illumina) identified serotypes, resistance genes, and virulence factors. Logistic regression analyzed associations between Salmonella carriage and host or environmental factors. Salmonella enterica carriage was detected in 8.7% of humans and 7.2% of poultry. Human isolates showed 24% resistance to cephalosporins, while poultry isolates showed 36.8% resistance. Resistance genes, including fosA7, qnrB19, and a cryptic aminoglycoside resistance gene, and virulence genes encoding T3SS-1 and T3SS-2, were detected in both hosts. Logistic regression indicated that residence in Sitaon and Zimidin was associated with ~70% lower odds of carriage (aOR = 0.3), while individuals aged 11–20 and 51–60 years had 2.8-fold higher odds. Carriage was also 60% higher during the rainy season. These findings suggest possible cross-transmission of Salmonella between humans and poultry and the circulation of resistant, potentially virulent strains in the community. Seasonal and age-related variations highlight environmental and behavioral influences on asymptomatic carriage. Integrated One Health surveillance and targeted hygiene interventions are essential to reduce Salmonella transmission and antimicrobial resistance in rural settings. Full article

Background/Objectives: With the global rise in chronic diseases among older adults, rehabilitation services have become essential, particularly for those with cerebrovascular and central nervous system (CNS) disorders, which lead to significant long-term disabilities. To determine the impact of designated rehabilitation medical institutions on the readmission rates of older patients with CNS disorders who receive surgical interventions. Methods: This was a population-based cohort study. Data was obtained from the National Health Insurance Service database (2002–2019). Fifteen designated institutions participated in the pilot project for convalescent rehabilitation. We analyzed the data of 1019 patients before and after the implementation of the designated rehabilitation institution. The study sample included (1) patients admitted to 15 designated institutions participating in the pilot project for convalescent rehabilitation and (2) patients diagnosed with conditions classified under the rehabilitation patient group, Rehabilitation Impairment Category 1 to 7. The intervention was the pilot project for designated rehabilitation institutions, launched in October 2017. The primary outcome of interest was the readmission rate of older patients with CNS disorders who received surgical interventions. Interrupted time series analysis with segmented regression was used to assess changes in the 30-day readmission rates. Results: Post-intervention, an 8% reduction in 30-day readmission rates (estimate, 0.9225; 95% confidence interval: 0.9129–0.9322, p < 0.0001) was observed. Subgroup analysis showed a significant decline in readmission rates across various patient groups, including those with disabilities, high Charlson Comorbidity Index scores, and extended hospital stays. The regions outside Seoul (capital city), particularly Gyeonggi/Incheon (areas around Seoul) and other areas (i.e., rural), also showed a significant decrease in readmission trends after the intervention. Conclusions: Designated rehabilitation medical institutions led to a significant reduction in readmission rates of older patients with CNS disorders, suggesting that these institutions effectively support recovery and reduce the burden of readmission for patients with severe conditions and those residing in non-capital cities.

The COVID-19 pandemic has underscored and intensified existing structural inequalities, particularly in urban centers of the Global South. This paper revisits the Sustainable Livelihoods Framework (SLF), originally designed for rural contexts, proposing its adaptation to centralize mobility as a critical analytical axis in urban contexts. Through an examination of São Paulo, Brazil, we explore how mobility restrictions, access to natural capital, and health outcomes intersected during the pandemic, disproportionately affecting vulnerable populations. To explore the application of the adapted framework, we analyze two contrasting neighborhoods in São Paulo, highlighting how different urban contexts mediate the impacts of systemic crises. By integrating mobility into the SLF, we aim to provide a more nuanced tool for analyzing and addressing urban vulnerabilities in times of systemic crises. Full article

Background/Objectives: Meaningful social connections are critical for well-being in later life, yet older adults living with HIV frequently experience social isolation and loneliness, compounded by stigma, mental health conditions, and systemic inequities. This study aimed to explore how older adults living with HIV and a concurrent mental health diagnosis experience social isolation and cultivate meaningful relationships, situating these experiences within Social Convoy Theory. Methods: Using a Heideggerian phenomenological approach, we conducted in-depth, semi-structured interviews with 33 adults aged 50 and older in Ontario, Canada, who self-identified as living with HIV and a diagnosed mental health condition. Participants were recruited through community-engaged strategies and snowball sampling. Data were analyzed iteratively, combining descriptive and interpretive coding to identify patterns in social isolation, relational meaning, and the influence of intersecting social, structural, and health determinants. Results: Participants described social isolation as both a physical and existential experience, influenced by stigma, mental health challenges, and contextual factors such as urban versus rural settings. Meaningful relationships were characterized by authenticity, trust, emotional safety, and reciprocity, often formed within peer networks sharing similar lived experiences. Community engagement and virtual platforms facilitated connection, while rural or suburban environments often intensified isolation. Relationships providing validation, agency, and continuity of experience were particularly impactful on participants’ well-being. Conclusions: Social isolation among older adults living with HIV and mental health conditions extends beyond objective network measures to include emotional and identity-related dimensions. Interventions should prioritize affirming, context-sensitive spaces that support disclosure, trust, and reciprocal relationships, recognizing the nuanced needs of this population for both social and existential connectedness.

Introduction: The health care burden of chronic hepatitis B virus (CHB) infection can be reduced by appropriate workup, treatment, and monitoring. Methods: As a primary objective, we determined whether adequate initial hepatitis B virus (HBV) laboratory workup in CHB patients is associated with improved CHB complications risk. Secondary outcomes assessed included: mortality, hospitalization, emergency department, and liver specialist visits. We conducted a retrospective cohort study from 1 January 2012 to 31 December 2018. Participants were followed from 12 months post index event until outcome occurrence, death, loss of eligibility, or 31 March 2023. Health administrative data from Ontario, Canada was utilized. The study cohort included individuals with at least one positive result of either hepatitis B surface antigen, hepatitis B e antigen, or HBV DNA viral load documented during the study window. The exposure of interest was defined as adequate laboratory workup, defined as having subsequent quantitative HBV DNA, and alanine aminotransferase testing completed within 12 months of the index event. CHB-related complications were assessed using previously validated diagnostic codes. Modified Poisson regression modelling was used to estimate relative risks. Results: The study cohort consisted of 30,794 CHB patients, with a mean age 45.7 years. The majority were male (53.5%) and within the lowest two income quintiles (50.2%). In total, 68.0% underwent adequate workup. Individuals with adequate workup were more likely to be older, male, urban based, and of the highest racialized and newcomer populations quintile. The risk for CHB complications was 1.50 (95% CI 1.36–1.65) times greater among those with adequate workup. By multivariable analysis, adequate workup was associated with a lower risk of mortality (RR 0.78; 95% CI 0.69–0.87), all-cause hospitalizations (RR 0.77; 95% CI 0.74–0.80), all-cause (RR 0.77; 95% CI 0.75–0.78), and liver-related (RR 0.67; 95% CI 0.60–0.75) ED visits. Conclusions: Adequate CHB clinical workup is associated with improved patient outcomes. Our findings advocate for the comprehensive evaluation of CHB patients using key laboratory tests to optimize clinical management and improve long-term health outcomes. We identified gaps in the workup of young adults, females, and those residing in rural settings, which should be addressed to ensure equity of HBV care. Full article

Background/Objective: Nutrition security, defined as consistent access to and consumption of nutritious foods that support health, remains a persistent challenge in rural populations. The HEALTHY (Helping Early Adolescents Live Their Healthiest Youth) program aimed to improve rural adolescents’ nutrition security through school-based strategies. This study evaluated its effectiveness by examining changes in fruit consumption, fruit waste, and skin carotenoid levels. Methods: A quasi-experimental, pre–post program was assessed in five rural middle schools (two experimental sites, three comparison sites). The programming paired four biweekly smoothie taste tests with nutrition education grounded in Social Cognitive Theory and Choice Architecture. Students in grades 3–8 (N = 149) participated. Digital tray photographs quantified selection and waste. The Veggie Meter^® assessed skin carotenoids on a scale from 0 to 800. Surveys captured perceptions and self-reported intakes. Analyses included χ², McNemar’s, GLMM, paired t-tests, and ANCOVA. Significance was set at p < 0.005. Results: At post-program, 98.3% of experimental trays contained the standard fruit option and/or a smoothie, compared with 41.0% of comparison trays (χ² = 41.66, p < 0.001). Fruit selection odds were 16.22 times higher in experimental schools (95% CI: 6.30–41.77, p < 0.001). Among trays with both (n = 39), smoothie waste was lower than the standard fruit option waste (t(38) = −7.10, p < 0.001, d = 1.14), resulting in greater estimated consumption (~0.43 vs. ~0.15 cups). Skin carotenoids increased in both groups, with greater improvement among experimental students in the lowest baseline quartile, F (1,19) = 9.20, p = 0.007, partial η² = 0.326. Conclusions: The HEALTHY program, which paired frozen-fruit smoothies with nutrition education, may offer a feasible and scalable approach to improving nutrition security among rural adolescents.

As population aging accelerates, the mounting burden on informal family caregivers in areas lacking formal care systems threatens the sustainability of elder care. This study aims at evaluating how the rural living environment and external connectivity jointly alleviate caregiver burden and exploring whether regional accessibility serves as a substitute for local infrastructure deficits. Guided by Ecological Systems Theory, we analyzed a cross-sectional dataset of 327 matched caregiver-recipient dyads from rural China using multivariate regression and mediation models. Results indicate that a favorable local environment reduces burden both directly and indirectly through improved recipient health. Crucially, county-level accessibility moderates this relationship via a substitution effect, where the marginal relief from local environmental improvements is most potent in isolated areas but diminishes where external access is convenient. Dimension-specific analyses show that developmental and physical strains are particularly sensitive to these factors. We conclude that sustaining informal care requires a dual-pathway strategy: prioritizing local “soft” assets like community safety and cultural activities while enhancing regional connectivity to service hubs. Ultimately, this research provides empirical evidence and a theoretical framework for enhancing rural informal care sustainability through environmental optimization, thereby advancing Sustainable Development Goals regarding health, reduced inequalities, and sustainable communities.

Background and Objectives: Cognitive disorders are a significant health problem in patients undergoing peritoneal dialysis and can profoundly impair both quality of life and treatment outcomes. Early identification of risk factors for the development of cognitive disorders in this population is therefore essential. This study aimed to (1) determine the prevalence of cognitive dysfunction in patients on peritoneal dialysis, (2) examine its association with sociodemographic characteristics, and (3) assess whether anaemia is associated with cognitive dysfunction in these patients. Materials and Methods: A cross-sectional study was conducted in November 2024 at the University Clinical Centre of Vojvodina, Clinic for Nephrology and Clinical Immunology, and included 36 patients on peritoneal dialysis. The Montreal Cognitive Assessment (MoCA) was used to evaluate cognitive function, while a structured questionnaire was used to collect sociodemographic data. Anaemia was determined based on haemoglobin levels. Results: Cognitive dysfunction was present in 69.4% of patients on peritoneal dialysis, while anaemia, as indicated by haemoglobin values, was present in 58.3% of the sample. Older age, rural residence, and lower haemoglobin levels were significantly associated with cognitive dysfunction in patients on peritoneal dialysis. Conclusions: Preserved cognitive function is a key prerequisite for the adequate implementation of peritoneal dialysis and for maintaining patients’ quality of life. The findings indicate the need for further research to identify effective strategies for preventing and treating anaemia, a factor associated with cognitive dysfunction in this patient population.

Background: Neurogenic bowel dysfunction (NBD) is a major chronic sequela of spinal cord injury (SCI) with substantial implications for rehabilitation and long-term management. However, population-level evidence describing how gastrointestinal (GI) diagnostic codes are used following SCI, particularly within administrative healthcare systems, remains limited. Methods: We conducted a nationwide retrospective cohort study using administrative claims data from the Korean National Health Insurance Service (NHIS). A total of 584,266 adults with trauma-related SCI encounters between 2009 and 2019 were identified. GI diagnostic codes—paralytic ileus (K56), irritable bowel syndrome (K58), and functional bowel disorders (K59)—were evaluated as administrative proxies for bowel dysfunction. Demographic characteristics, disability status, regional factors, and health behaviors were analyzed using multivariable logistic regression. Results: GI diagnostic codes were frequently recorded after SCI, most commonly irritable bowel syndrome (approximately 30%) and functional bowel disorders (approximately 37%), whereas paralytic ileus was uncommon. Greater disability severity, female sex, older age, and rural residence were consistently associated with higher odds of GI diagnostic coding. Physical activity showed robust inverse associations across all models. Inverse associations observed with smoking and alcohol consumption were interpreted as reflecting residual confounding or health-related selection, rather than biological protective effects. Conclusions: Patterns of GI diagnostic coding after SCI likely reflect the clinical burden and management needs of neurogenic bowel dysfunction within healthcare systems, rather than the development of new gastrointestinal diseases. These findings underscore the importance of individualized bowel management, incorporation of structured physical activity into rehabilitation programs, and equitable access to SCI rehabilitation services, particularly for individuals with greater disability or those living in rural areas.

Cervical cancer is a largely preventable disease, with over 90% of cases caused by persistent infection with human papillomavirus (HPV). Despite the availability of HPV vaccination and cervical screening, incidence rates in Canada have been rising since 2015, particularly among underserved populations. This study investigates contributing factors behind cervical cancer diagnoses in Eastern Ontario over a two-year period to identify gaps leading to failures in prevention and screening. A retrospective chart review was conducted for cervical cancer cases diagnosed between January 2022 and December 2023 at two regional cancer centres in Eastern Ontario. Cases were categorized as screen-detected, inadequately screened, or system failure, based on prior screening history and care processes. Data was collected on patient, screening, and cancer characteristics. Of 132 cases, 22 (16.7%) were screen-detected, 73 (55.3%) were inadequately screened, and 37 (28.0%) were attributed to healthcare system failure. Later-stage disease was significantly more common in the latter two groups. Thirty-one (23.5%) cases presented with palliative diagnoses, and 18 (13.6%) individuals died within 2.5 years. Inadequate screening was associated with rurality, deprivation, and lack of a primary care provider. System failures included false-negative Pap tests, loss to follow-up, and misapplication of screening guidelines. This study evaluated failures in cervical cancer prevention, which led to cervical cancer diagnoses in Eastern Ontario. Gaps included suboptimal screening participation, lack of access to care, health care system breakdowns, and limitations of the Pap test. Findings provide concrete suggestions for eliminating cervical cancer in Canada. Full article

Background: Chronic pain is a leading contributor to disability worldwide, yet population-based data from rural and medically underserved settings remain limited. Evidence describing the biopsychosocial correlates of chronic pain in rural Filipino communities is particularly scarce. Methods: We conducted a secondary analysis of cross-sectional data from the I-HELP-FILIPINO community cohort, collected between January and June 2017. Participants included 909 adults aged 18–93 years who voluntarily attended barangay clinic days in rural Philippine communities. Pain severity was assessed with standardized self-report tools. Sociodemographic, psychosocial, sleep, and functional health factors were examined using bivariate analysis and hierarchical linear regression. Results are shown with 95% confidence intervals. Results: Chronic pain was very common, affecting 83.8% of participants, with 5.6% experiencing severe pain. In multivariable models, psychosocial distress, sleep issues, and reduced physical functioning were significantly linked to increased pain severity, while demographic factors contributed minimally to the variance. Most of the explained variance in pain outcomes was accounted for by psychosocial and clinical variables. Conclusions: In this rural Filipino cohort, chronic pain was strongly associated with modifiable psychosocial, sleep, and functional health factors. Focusing on community-based and culturally tailored interventions can inspire hope and empower healthcare professionals and policymakers to tackle these issues more effectively. Full article

This study suggests the concept of multifunctional social spaces (MSSs) as intergenerational communication platforms, contributing to SDG achievement and environment awareness in local communities. Retirees could perform socially significant practices via local MSS premises supported by municipalities and initiative groups. The basic social vector of an MSS is supposed to produce a synergy effect with the educational and environmental impetus of the Sustainable Environmental Education (SEE) approach. Lifelong education underlies the process of adapting various age groups to different local spaces, namely metropolis, suburb, or rural areas. Test qualitative interviews were conducted with pensioners and young people to discover attitudes towards MSS-prescribed functions within different reference groups. These interviews helped to define the preferred communication instruments for MSS operation. General types of MSSs were classified based on mini case studies. MSS introduction is supposed to influence basic social indices such as population health, life expectancy, and fertility levels in the long term, and support several environmental awareness markers. Future studies could examine such influences in detail and discuss more national and regional specifics. Municipal and regional authorities, as well as local community leaders, could use the results of this study to consider local development, SDG strategies, and roadmaps. Full article

Background: Multimorbidity (the co-occurrence of two or more chronic conditions) is increasingly common among older adults and contributes to diminished well-being and greater healthcare use. While national data highlight regional variation, few studies have examined how multimorbidity is patterned within provinces like Saskatchewan or how it relates to access and acute care use. Objective: To describe sociodemographic and geographic patterns of multimorbidity among older adults in Saskatchewan and examine its association with healthcare access, unmet needs, and recent emergency department (ED) visits and hospitalizations. Methods: We conducted a secondary analysis of a population-based telephone survey of 1093 adults aged 65+ across Saskatchewan. Respondents were categorized by chronic disease burden (none, one, or multimorbidity). Descriptive statistics and postal code-level mapping explored health status, access, and utilization. Results: Multimorbidity (10.6%) was more prevalent among older adults aged 75+, Indigenous respondents, and those with lower education. It was associated with poorer self-rated health, greater unmet needs, and higher ED visits (20.7%) and hospitalizations (12.1%) compared to those without chronic conditions. Northern regions had proportionally higher multimorbidity, despite smaller populations. Conclusions: Findings highlight social and spatial disparities in chronic disease burden and underscore the need for equity-focused strategies in Saskatchewan’s rural and northern communities.

Background: Congenital diaphragmatic hernia (CDH) is a rare but serious congenital anomaly linked to high mortality rates and significant long-term morbidity. Although numerous prognostic factors for short-term outcomes have been identified through hospital-based studies, data on long-term mortality at the population level are limited. Specifically, nationwide assessments of long-term outcomes for infants with CDH are scarce. This study aimed to estimate the national 5-year all-cause mortality for CDH and to create a population-level risk stratification nomogram utilizing nationwide health insurance claims data. Methods: We conducted a retrospective cohort study of infants with CDH using nationwide insurance claims data from 2002 to 2016, allowing for complete 5-year follow-up. We analyzed population-level demographic and clinical proxy variables with Cox proportional hazards models and developed a nomogram for long-term mortality risk stratification. Results: Factors such as rural residence, middle-to-high SES, respiratory distress in newborns, and CHD were associated with increased 5-year mortality in infants with CDH. The claims-based nomogram, which incorporated sociodemographic and comorbidity variables, demonstrated moderate discriminatory power (AUC 0.76; C-index 0.78) for population-level risk stratification. Conclusions: This nationwide claims-based cohort study provides population-level estimates of 5-year mortality associated with CDH and introduces a nomogram that offers moderate discriminatory ability for long-term risk stratification.
