Suicide is a growing public health concern in Brazil, with significant increases in mortality rates over the last decade and disparities among vulnerable populations. This study aimed to systematically synthesize the recent literature reviews on suicidality and suicide prevention in Brazil, providing an overview of key findings, research gaps, and implications for future studies. This systematic review of reviews follows a pre-registered PROSPERO protocol (CRD42024561892). Searches across five databases (MEDLINE, Scopus, CINAHL, SciELO and LILACS) identified 10 eligible reviews, published between 2019 and 2024, including systematic, integrative, narrative reviews, and meta-analyses. The reviews examined populations such as Indigenous peoples, adolescents, university students, older adults, and healthcare professionals. Findings showed that the risk of suicidal behavior was associated with mental health conditions, social vulnerability, and limited access to mental health services. Particularly high suicide rates were observed among Indigenous populations and adolescents. Across reviews, a lack of interventional studies, limited geographical coverage, and the inadequate training of health professionals were recurrent themes. This review highlights the urgent need for culturally sensitive suicide prevention strategies, greater research investment in underserved populations, and improved healthcare training and coordination. These findings aim to support the development of more effective national suicide prevention policies. Full article

Background: Adolescents in Ethiopia, particularly in rural areas, face significant barriers to accessing comprehensive sexual and reproductive health (SRH) services, resulting in poor health outcomes. The youth-friendly health services (YFHS) initiative addresses these challenges by training Health Extension Workers (HEWs) to deliver tailored, age-appropriate care at the primary care level. This study evaluates the cost-effectiveness of YFHS implementation in rural health posts in the Jimma Zone, Ethiopia. Methods: Using an ingredient-based costing approach, costs were analyzed across six health posts, three implementing YFHS and three offering routine services. Health outcomes were modeled using disability-adjusted life years (DALYs) averted, and incremental cost-effectiveness ratios (ICERs) were calculated. Results: Results showed that YFHS reached 9854 adolescents annually at a cost of USD 29,680, compared to 2012.5 adolescents and USD 7519 in control sites. The study showed the ICER of USD 25.50 per DALY averted. The intervention improved health outcomes, including a 27% increase in antenatal care uptake, a 34% rise in contraceptive use, and a 0.065% reduction in abortion-related mortality, averting 52.11 DALYs versus 26.42 in controls. Conclusions: The ICER was USD 25.50 per DALY averted, well below Ethiopia’s GDP per capita, making it highly cost-effective by WHO standards. Scaling YFHS through HEWs offers a transformative, cost-effective strategy to advance adolescent SRH equity and achieve universal health coverage in Ethiopia. Full article

In the United States, adolescents and young adults between the ages of 16 and 23 have high rates of serogroup B meningococcal infections due to an elevated risk for those attending college. This review examines meningococcal vaccination requirements and recommendations for college students in the United States, with a focus on state-level mandates. National stakeholder resources, state legislatures, and official state Department of Health and Department of Education websites were analyzed for each state and Washington, DC. Overall, 26 states mandate MenACWY vaccination for college entry, whereas only 2 have specific requirements for MenB vaccination. Among the six states with the largest state university campus enrollments, half mandate MenACWY vaccination for college students, whereas none mandate MenB. By region, the Northeast had the highest percentage of states with a MenACWY requirement for college entry (77.8%) followed by the South (64.7%), Midwest (41.7%), and West (23.1%). Further research is needed to elucidate the relationship between state mandates and coverage to aid in optimizing meningococcal vaccination for college students. Full article

Background: In Canada, despite universal healthcare coverage, dental care remains predominantly privately financed, creating financial barriers that prevent many from accessing essential services. This case study is part of a larger initiative, the One Smile Research program, which evaluates the impact of cost-free dental care on the oral health and overall well-being of individuals who have been unable to access dental services in the past two years due to financial constraints. Participants in the program receive necessary dental care and attend follow-up appointments to assess the long-term effects of continuous cost-free care. Clinical Case: This mixed-methods case report focuses on a 26-year-old male participant and integrates a qualitative semi-structured interview with clinical and self-reported data, providing an in-depth understanding of his experiences. Results: Clinical outcomes demonstrated the effectiveness of the provided dental treatments, while self-reported measures indicated improved oral health, satisfaction with dental appearance, enhanced psychosocial well-being, increased self-esteem, reduced dental anxiety, and better oral hygiene habits. The qualitative interview identified three key themes reflecting positive experiences with the program: ease of admission, staff kindness, and overall well-being improvement. The integration of both quantitative and qualitative analyses revealed significant advancements in both objective and subjective measures, particularly regarding overall well-being. Conclusions: The continuity of cost-free dental care effectively addressed the participant’s oral health and overall well-being, with most benefits sustained even at the two-year follow-up. These individual-level outcomes offer preliminary insight into the potential advantages of universal dental coverage within the Canadian healthcare system. Full article

The Sustainable Development Goals commit states to Universal Health Coverage (UHC) for all; yet displaced populations—including asylum seekers, refugees, internally displaced persons (IDPs), and undocumented migrants—remain systematically excluded from national health systems across southern and eastern Africa. This paper applies a whole-of-route, rights-based framework to examine how legal status, policy implementation, and structural governance shape healthcare access for displaced populations across South Africa, Kenya, Somalia, and the Democratic Republic of Congo (DRC). Drawing on 70 key informant interviews and policy analysis conducted between 2020 and 2025, the study finds that despite formal commitments to health equity, access remains constrained by restrictive legal regimes, administrative discretion, and fragmented service delivery models. Critical gaps persist in migration-sensitive planning, gender-responsive care, and mental health integration. The findings highlight the limitations of rights-based rhetoric in the absence of legal coherence, intersectoral coordination, and political will. To realise UHC in displacement contexts, health systems must move beyond citizen-centric models and embed migration-aware, inclusive, and sustainable approaches across all stages of displacement. Without such structural reforms, displaced populations will remain at the margins of national health agendas—and the promise of health for all will remain unmet. Full article

Urban green spaces (UGSs), including parks, forests, and community gardens, play a critical role in enhancing public health and well-being by providing essential ecosystem services such as improving air quality, reducing surface temperatures, and mitigating harmful substances. As urbanization accelerates, especially in rapidly growing cities like Jinan, China, the demand for UGSs is intensifying, necessitating careful urban planning to balance development and environmental protection. While previous studies have often focused on city-level green coverage, this study shifts the analytical focus from UGS as a whole to urban functional units (UFUs), allowing for a more detailed examination of how green space is distributed across different land use types. We investigate UGS changes in Jinan over the past two decades and assess the influence of socio-economic factors—such as housing prices, land use types, and building age—on UGS distribution within UFUs. Remote sensing technology was employed to analyze the spatiotemporal dynamics of UGS and its correlation with these variables. Our findings reveal a significant shift in UGS distribution, with parks and leisure areas becoming primary drivers of UGS expansion. This study also highlights the growing influence of economic factors, particularly housing prices, on UGS distribution in more affluent UFUs. Additionally, while UGS in Jinan has generally expanded, challenges remain in balancing green space with urban expansion, especially in commercial and residential UFUs. This paper contributes to a more nuanced understanding of UGS distribution by integrating the UFU framework and identifying socio-economic drivers—including housing prices, construction age, and land use type—that shape green space patterns in Jinan. Our findings demonstrate that the spatial pattern of UGS in Jinan mirrors socio-economic and land use disparities observed in other global cities, highlighting both the universality of these patterns and the need for targeted planning in rapidly urbanizing contexts.

Background: Health and safety are critical pillars of functional higher education systems. In South African universities, recurring incidents have highlighted vulnerabilities, particularly concerning gender-based violence (GBV), student housing conditions, infrastructure safety, and campus crime. Methods: This study employed a document-based qualitative approach, analysing public records, police reports, campus press statements, and national media coverage of incidents reported at South African universities (2015 to 2024). The study is guided by public health and victimology frameworks to examine systemic risk factors and institutional responses. Results: The findings indicate increased reports of GBV, multiple student deaths related to substandard residence conditions, infrastructure-related fatalities, and a lack of consistent institutional safety policies. A pattern of poor infrastructure management, weak inter-institutional communication, and failure to implement recommendations following major incidents emerged across the dataset. Conclusions: South African universities remain exposed to preventable student risks. Targeted interventions, mandatory safety audits, emergency response units, and accountability structures are urgently needed to address systemic failings and protect student welfare. The study supports Sustainable Development Goals 3 and 4 by linking campus safety to student well-being and equitable access to higher education. Full article

Background/Objectives: Tick-borne encephalitis (TBE) is a notifiable disease in Poland, with the highest incidence in the northeastern region. Although vaccination is highly effective, breakthrough infections occasionally occur. This study aimed to describe the clinical features of vaccinated and unvaccinated TBE cases, assess long-term hospitalization trends, and estimate vaccine effectiveness (VE) in a highly endemic region. Methods: We retrospectively analyzed 1518 laboratory-confirmed TBE cases hospitalized at the University Clinical Hospital in Białystok, Poland, from 1988 to 2020. Clinical and cerebrospinal fluid (CSF) parameters were compared between vaccinated and unvaccinated individuals. Vaccine effectiveness was estimated using the screening method, based on aggregated regional vaccine uptake data from 1999 to 2020. Results: Among all cases, 13 (0.9%) occurred in individuals who had received at least one dose of vaccine, including 4 who had completed the full primary vaccination schedule. Hospitalized vaccinated patients showed similar demographic and clinical characteristics compared to unvaccinated patients, though CSF findings suggested an earlier and more dynamic immune response. Seasonal analysis revealed a sustained increase in TBE hospitalizations and a possible extension of the transmission season into late summer and autumn. Estimated VE was 94.4% (95% CI 85.2–97.9%), though this should be interpreted with caution due to the small number of vaccinated cases and assumptions regarding population-level coverage. Conclusions: This study provides detailed clinical data on breakthrough TBE cases and long-term epidemiological insights from an endemic region in Poland. While vaccine effectiveness appears high, low uptake remains a public health concern. These findings underscore the need for improved vaccination coverage and ongoing surveillance to monitor evolving transmission patterns. Full article

The 8th meeting of the African Advisory Committee on Vaccine Safety (AACVS), constituted in 2021, convened by the Vaccine Research and Innovation Unit within the Vaccine Preventable Diseases Program, WHO Regional Office for Africa, was held virtually from 14 to 16 April 2025. The meeting brought together independent vaccine experts to provide advice to the Regional Director, WHO, on vaccine safety issues critical to the African region. Discussions focused on critical updates regarding ongoing regional outbreaks, safety data, and associated safety concerns, with emphasis on newly introduced vaccines, including the malaria vaccines (RTS, S and R21), the MenFive pentavalent meningitis vaccine, and the Mpox vaccines—MVA-BN and LC16—alongside the ongoing Mpox response. The Committee conducted a deep dive into comprehensive safety considerations for new vaccine introduction, active surveillance strategies, strengthening the responsiveness of pharmacovigilance systems, and advancing vaccine research and development in Africa. Key observations highlighted significant gaps in safety surveillance systems. These included delays in data collection, access, and signal detection; a lack of harmonized real-time monitoring frameworks; the underutilization of digital technologies; and inadequate manufacturer responsibilities and accountability in post-market safety monitoring. The meeting concluded with a call to action emphasizing the need for sustainable pharmacovigilance funding mechanisms, improved regional coordination, real-time data sharing, standardized early safety study protocols, strengthened manufacturer accountability, and investments in risk communication and community engagement to bolster public trust. Strengthening vaccine safety systems and enhancing regional collaboration were recognized as urgent priorities to support the safe and effective deployment of vaccines and protect public health across Africa.

Background: Respiratory syncytial virus (RSV) poses a significant health burden in children, being the major cause of lower respiratory tract infection (LRTI), including bronchiolitis. During the 2023–2024 RSV season, Spain introduced nirsevimab, a monoclonal antibody for universal RSV prophylaxis in infants. This study reviews the safety of nirsevimab through post-marketing surveillance. Material and Methods: A descriptive pharmacovigilance study was made based on spontaneous reporting data of suspected adverse events (SAEs) from the Spanish Pharmacovigilance System for Medicinal Products for Human Use (SEFV-H) and industry reports. SAEs reported between September 2023 and May 2024 were extracted from the Spanish Pharmacovigilance Adverse Reactions Data (FEDRA) database. Cases were analysed by sex, age, severity, and SAEs classification using the Preferred Terms (PT) level of the Medical Dictionary for Regulatory Activities (MedDRA). Reporting rates were estimated based on immunization coverage and birth data. Results: Sixty-seven cases reported 141 SAEs, yielding an overall rate of 23.1 cases per 100,000 doses. Common events included rash (8.51%), drug ineffectiveness (7.09%), and pyrexia (7.09%). Serious events constituted 53.70% of reports, including two fatalities (3.00%). No new safety signals or unexpected risks, such as antibody-dependent enhancement (ADE), were identified. Discussion: SAEs reported peaked early in the campaign, reflecting heightened reporting in new immunization programs. The safety profile aligns with clinical trial findings and regulatory expectations, confirming nirsevimab’s benefit–risk balance. Continued pharmacovigilance is critical for maintaining public trust in RSV prophylaxis. Nirsevimab demonstrated a favorable safety profile during Spain’s initial universal RSV immunization campaign in infants, supporting its continued use in reducing RSV-related morbidity. Full article

HIV/AIDS remains a global public health concern, with a high prevalence in sub-Saharan Africa. The President’s Emergency Plan for AIDS Relief (PEPFAR) initiatives, including preexposure prophylaxis (PREP) and postexposure prophylaxis (PEP), significantly reduced HIV infections in South Africa and Nigeria. The suspension of United States (U.S.) foreign aid may impact these preventive measures. Although some emergency aid programs were exempted, uncertainty persists, impacting global health initiatives, especially in South Africa and Nigeria. This study investigates the public health impacts of the United States (U.S.) government’s January 2025 suspension of U.S. foreign aid, focusing on its implications for HIV prevention initiatives, such as PREP and PEP, in South Africa and Nigeria. We comprehensively searched keywords such as PEPFAR, PREP, PEP, HIV infection in South Africa or Nigeria, antiretroviral (ARV) drugs, public healthcare impact, 2025 Trump’s foreign aid withdrawal, titles, and abstracts in Google Scholar, PubMed, and Web of Science. The search results were screened from 500 to 150 included articles based on their relevance and quality assessment for inclusion. The review unveiled that Nigeria maintained a continuous increase in HIV/AIDS-related deaths and new HIV infections from 1990, reaching the climax between 1999 and 2005, showing approximately 110,000 HIV/AIDS-related deaths and 200,000 new HIV infections. Notably, due to the PEPFAR intervention in Nigeria, an improved decrease in both HIV/AIDS-related deaths (45,000) and new HIV infections (75,000) was experienced from 2010 to 2023. South Africa experienced a rapid increase between 1990 and 2003 in both HIV/AIDS-related deaths and new HIV infections, reaching the climax around the early 2000s, with about 520,000 new HIV infections and 260,000 HIV/AIDS-related deaths in 2005. Furthermore, there was a continuous decline from 2005 onwards, with 50,000 HIV/AIDS-related deaths and 150,000 new HIV infections by 2023. Therefore, the suspension of this aid threatens disruptions in ARV therapy, possible increases in HIV transmission, shortages in PREP and PEP, the retrenchment of healthcare workers, the suspension of non-governmental organization activities, and the reversal of gains in vulnerable populations, reversing progress toward the 95-95-95 vision, increasing morbidity and mortality rates and financial strain on healthcare systems in these two countries. We recommend proactive measures, such as increased budget allocations for healthcare reforms, exploring local vaccine and health product development and diversifying funding sources in Nigeria, and implementing universal healthcare coverage for South Africans to mitigate the adverse consequences of aid withdrawal.

Background: Despite the significant global disease burden associated with HPV infection, the vaccination coverage among female college students in China remains suboptimal. This study aimed to examine HPV vaccination coverage, knowledge levels, and determinants influencing vaccination behavior among female college students in northern China, utilizing the Health Belief Model (HBM) as a theoretical framework. Methods: A cross-sectional online survey was conducted from December 2024 to January 2025, involving 4076 female students from six universities in Jinan, China. The participants were categorized into three groups: vaccinated (VG), willing-to-vaccinate (WTG), and unwilling-to-vaccinate (UTG). Data on sociodemographic characteristics, HPV knowledge, health beliefs, and vaccination behavior were analyzed using ANOVA, chi-square tests, correlation analysis, and multivariate logistic regression. Results: The vaccination rate was 18.11%, with 40.19% expressing willingness to vaccinate and 41.71% expressing unwillingness. Vaccinated students demonstrated higher levels of HPV knowledge (6.66 ± 2.67 compared to 4.76 ± 3.10 in the UTG, p < 0.001) and were predominantly from urban areas (OR = 0.64, p < 0.001). The key determinants of vaccination uptake included perceived benefits (OR = 1.54, p < 0.001), perceived barriers (OR = 3.34, p < 0.001), self-decision-making ability (OR = 1.80, p < 0.001), and social motivation (OR = 0.21, p < 0.001). Notably, increased knowledge was associated with vaccine hesitancy in the WTG group (OR = 0.45, p < 0.001), indicating that information overload may adversely affect decision-making processes. Structural barriers, such as cost (42.63%), safety concerns (46.59%), and misconceptions (e.g., 57.76% cited “no sexual activity” as a reason for refusal), significantly impeded vaccine uptake. Conclusions: The low coverage of HPV vaccination is indicative of deficiencies in knowledge, socioeconomic disparities, and cultural perceptions. Tailored interventions should focus on educational efforts to correct misconceptions, provide subsidized access to vaccines, and implement empowerment strategies that enhance self-efficacy and informed decision-making. Policymakers should incorporate these findings into national cervical cancer prevention programs to address the gap between vaccination intention and behavior among young women in China.

Background/Objectives: The Brazilian Unified Health System was established in 1988 as a public health system with principles of universality, equity, and integrality. One of Brazil’s main strategies to strengthen universal healthcare is the Family Health Strategy (FHS), a primary health care policy established in 1994 and fully incorporated in the country in 2006. This study aims to describe the time trends of FHS coverage in Brazil and its states from 2008 to 2023 and to correlate this coverage with the states’ Human Development Index (HDI). Methods: Data on the number of FHS teams, population, and HDI during the period were collected for each Brazilian state in the Brazilian Ministry of Health’s public-access databases. Prais–Winsten regression was used to conduct a time series analysis for each state and country. The annual percentage change (APC) was used to describe time trends in time series. Linear regression was used to identify a correlation between HDI and FHS coverage across states. Results: The FHS coverage in the country increased from 66.81% to 84.66% from 2009 to 2023. Disparities in coverage between regions are evident throughout the entire study period. The Northeast region (NE) exhibited higher FHS coverage but lower APC rates compared to other regions. Results suggest a negative correlation between HDI and FHS coverage in all Brazilian states for 2009, 2012, 2015, 2018, 2021, and 2023. Conclusions: The FHS coverage increased in Brazil and its states during the period. The highest coverages were found in states from the North (N) and NE regions, and the lowest were in the Southeast region. Nine federative units achieved full coverage (100%) and maintained it afterward, with seven from the N and NE. A negative correlation was found between FHS and HDI, suggesting that the expansion of FHS effectively targets vulnerable populations. Full article

Despite growing concern, there is limited comprehensive and up-to-date research on the burden, disparities, and inequalities of depressive disorders in the Western Pacific region. We obtained data from the Global Burden of Disease Study (GBD; 2021) for the Western Pacific region. We reported the prevalence and disability-adjusted life years (DALYs) rates of depressive disorders from 1990 to 2021. Our results showed that the prevalence of depressive disorders in the Western Pacific region was 1723.1 per 100,000 people (95% UI: 1359.2–2164.9), contributing to 1057.3 DALYs per 100,000 (95% UI: 683.0–1551.8). From 1990 to 2021, the burden of depressive disorders initially decreased but then increased, with Japan, Malaysia, and South Korea seeing the most significant rise. The burden grew with age, especially in the 10–14 age group, and exhibited significant sex disparities, especially in this age group. Among 31 countries, those with higher UHC scored had higher prevalence rates, but the gap between high- and low-UHC countries has decreased over time, indicating that countries with lower UHC might face greater challenges in the future. Our results highlight the differences in burden by sex and age call for targeted policies and interventions to promote youth mental health. Accelerating universal health coverage could be a key strategy to further reduce this high burden. Full article

Background: high levels of stress have hazardous impacts on nurses’ health, well-being, job satisfaction, and abilities to cope with the job demands, which in turn may impact the provision of quality patient care, which is essential for universal health coverage. Aim: to investigate the relationship of perceived stress related to personality traits, chronotype, and eating behaviour among hospital and community nurses in Brunei. Methods: A cross-sectional survey on nurses from public hospitals and community health centres from all four districts in the country. The questionnaire included Perceived Stress Scale to measure stress levels, the brief Big Five Inventory to identify personality, the Morningness-Eveningness Questionnaire to identify chronotype, and the Sakata Eating Behaviour Questionnaire to identify eating behaviour. Subgroup analysis and partial least squares structural equation modelling were applied. Results: The structural equation model revealed that personality trait (β = 0.482) is the most salient and strongest factor contributing to perceived stress, followed by chronotype profile (β = 0.45), accounting for 71.4% of the variance explained for perceived stress. Whereas perceived stress (β = 0.719) is a factor affecting eating behaviour, which accounts for 51.6% of the variance explained for eating behaviour. Conclusions: This study revealed that neuroticism and evening chronotype are significant stress predictors. Stress affects eating habits, with stressed nurses showing poor eating patterns. Older and single nurses report higher stress. Full article
