UNASSIGNED: Air pollution is one of the biggest problems in societies today. The intensity of indoor and outdoor air pollutants and the urbanization rate can cause or trigger many different diseases, especially lung cancer. In this context, this study\'s aim is to reveal the effects of the indoor and outdoor air pollutants, and urbanization rate on the lung cancer cases.
UNASSIGNED: Panel data analysis method is applied in this study. The research includes the period between 1990 and 2019 as a time series and the data type of the variables is annual. The dependent variable in the research model is lung cancer cases per 100,000 people. The independent variables are the level of outdoor air pollution, air pollution level indoor environment and urbanization rate of countries.
UNASSIGNED: In the modeling developed for the developed country group, it is seen that the variable with the highest level of effect on lung cancer is the outdoor air pollution level.
UNASSIGNED: In parallel with the development of countries, it has been determined that the increase in industrial production wastes, in other words, worsening the air quality, may potentially cause an increase in lung cancer cases. Indoor air quality is also essential for human health; negative changes in this variable may negatively impact individuals\' health, especially lung cancer.

High-income countries like Aotearoa New Zealand are grappling with inequitable access to healthcare services. Out-of-pocket payments can lead to the reduced use of appropriate healthcare services, poorer health outcomes, and catastrophic health expenses. To advance our knowledge, this systematic review asks, \"What interventions aim to reduce cost barriers for health users when accessing primary healthcare in high-income countries?\" The search strategy comprised three bibliographic databases (Dimensions, Embase, and Medline Web of Science). Two authors selected studies for inclusion; discrepancies were resolved by a third reviewer. All articles published in English from 2000 to May 2022 and that reported on outcomes of interventions that aimed to reduce cost barriers for health users to access primary healthcare in high-income countries were eligible for inclusion. Two blinded authors independently assessed article quality using the Critical Appraisal Skills Program. Relevant data were extracted and analyzed in a narrative synthesis. Forty-three publications involving 18,861,890 participants and 6831 practices (or physicians) met the inclusion criteria. Interventions reported in the literature included removing out-of-pocket costs, implementing nonprofit organizations and community programs, additional workforce, and alternative payment methods. Interventions that involved eliminating or reducing out-of-pocket costs substantially increased healthcare utilization. Where reported, initiatives generally found financial savings at the system level. Health system initiatives generally, but not consistently, were associated with improved access to healthcare services.

UNASSIGNED: Understanding how patent expirations affect drug prices is crucial because price changes directly inform accurate cost-effectiveness assessments. This study investigates the association between patent expirations and drug prices in 8 high-income countries and evaluates how the changes affect cost-effectiveness assessments.
UNASSIGNED: To analyze how the expiration of drug patents is associated with drug price changes and to assess the implications of these price changes for cost-effectiveness evaluations.
UNASSIGNED: This cohort study performed an event study design using data from 8 high-income countries to assess the association between patent expiration and drug prices, and created a simulation model to understand the implications for cost-effectiveness analyses. The simulation cost-effectiveness model analyzed the implications of including or ignoring postpatent price dynamics.
UNASSIGNED: Drug patent expiration.
UNASSIGNED: Change in drug prices and differences in incremental cost-effectiveness ratios when considering vs ignoring postpatent price dynamics.
UNASSIGNED: The sample comprised 505 drugs undergoing patent expiration in Australia, Canada, France, Germany, Japan, Switzerland, UK, and US. Price decreases were statistically significant over the 8 years after patent expiration, with the fastest price declines observed in the US: 32% (95% CI, 24%-39%) in year 1 after patent expiration and 82% (95% CI, 71%-89%) in the 8 years after patent expiration. Estimates for other nations ranged from a decrease of 64% in Australia to 18% in Switzerland in the 8 years after expiration. The cost-effectiveness simulation model indicated that not accounting for generic entry into the market may produce biased incremental cost-effectiveness ratios of 40% to -40%, depending on the scenario.
UNASSIGNED: The findings of this cohort study demonstrate that drug prices were reduced substantially after patent expirations in high-income countries. Therefore, incorporating information on patent status and pricing dynamics in cost-effectiveness assessment analyses is necessary for producing accurate economic evaluations of new drugs.

UNASSIGNED: This study aimed to systematically appraise risk factors associated with SARS-CoV-2 infection in high-income countries during the period of predominance of the Alpha variant (January 2020 to April 2021).
UNASSIGNED: Four electronic databases were used to search observational studies. Literature search, study screening, data extraction and quality assessment were conducted by two authors independently. Meta-analyses were conducted for each risk factor, when appropriate.
UNASSIGNED: From 12,094 studies, 27 were included. The larger sample size was 17,288,532 participants, more women were included, and the age range was 18-117 years old. Meta-analyses identified men [Odds Ratio (OR): 1.23, 95% Confidence Interval (CI): 1.97-1.42], non-white ethnicity (OR: 1.63, 95% CI: 1.39-1.91), household number (OR: 1.08, 95% CI: 1.06-1.10), diabetes (OR: 1.22, 95% CI: 1.08-1.37), cancer (OR: 0.82, 95% CI: 0.68-0.98), cardiovascular diseases (OR: 0.92, 95% CI: 0.84-1.00), asthma (OR: 0.83, 95% CI: 0.75-0.92) and ischemic heart disease (OR: 0.82, 95% CI: 0.74-0.91) as associated with SARS-CoV-2 infection.
UNASSIGNED: This study indicated several risk factors for SARS-CoV-2 infection. Due to the heterogeneity of the studies included, more studies are needed to understand the factors that increase the risk for SARS-CoV-2 infection.

BACKGROUND: Shifting demographics, an aging population, and increased healthcare needs contribute to the global healthcare worker shortage. Migrant Health Care Workers (MHCWs) are crucial contributors to reducing this shortage by moving from low-and middle-income countries (LMICs) to high-income countries (HICs) for better opportunities. Economic factors and health workforce demand drive their migration, but they also face challenges adapting to a new country and new working environments. To effectively address these challenges, it is crucial to establish evidence-based policies. Failure to do so may result in the departure of Migrant Healthcare Workers (MHCWs) from host countries, thereby worsening the shortage of healthcare workers.
OBJECTIVE: To review and synthesize the barriers experienced by MHCWs as they adjust to a new country and their new foreign working environments.
METHODS: We followed the PRISMA guidelines and conducted a search in the PubMed and Embase databases. We included cross-sectional studies published after the year 2000, addressing MHCWs from LMIC countries migrating to high-income countries, and published in English. We established a data extraction tool and used the Appraisal tool for Cross-Sectional Studies (AXIS) to assess article quality based on predetermined categories.
RESULTS: Through a targeted search, we identified fourteen articles. These articles covered 11,025 MHCWS from low- to medium-income countries, focusing on Europe, the USA, Canada, Australia, New Zealand, and Israel. Participants and respondents\' rates were diverse ranging from 12% to 90%. Studies encompassed various healthcare roles and age ranges, mainly 25-45 years, with a significant female presence. Participants resided in host countries for 3-10 years on average. Results are categorized based on the Riverside Acculturation Stress Inventory (RASI) and expanded to include bureaucratic and employment barriers, Gender differences, Natives vs. non-natives, and orientation programs.
CONCLUSIONS: The findings emphasize the importance of cultural competence training and tailored support for MHCWs integration and job satisfaction. Time spent in the new healthcare setting and the influence of orientation programs are key factors in shaping their intentions to stay or leave. Despite limitations, these studies provide valuable insights, emphasizing the ongoing need for holistic strategies to facilitate successful integration, ultimately benefiting healthcare systems and well-being for all stakeholders.

BACKGROUND: Most older adults wish to remain in their homes and communities as they age. Despite this widespread preference, disparities in health outcomes and access to healthcare and social support may create inequities in the ability to age in place. Our objectives were to synthesise evidence of social inequity in ageing in place among older adults using an intersectional lens and to evaluate the methods used to define and measure inequities.
METHODS: We conducted a mixed studies systematic review. We searched MEDLINE, EMBASE, PsycINFO, CINAHL and AgeLine for quantitative or qualitative literature that examined social inequities in ageing in place among adults aged 65 and older in Organisation for Economic Co-operation and Development (OECD) member countries. Results of included studies were synthesised using qualitative content analysis guided by the PROGRESS-Plus framework.
RESULTS: Of 4874 identified records, 55 studies were included. Rural residents, racial/ethnic minorities, immigrants and those with higher socioeconomic position and greater social resources are more likely to age in place. Women and those with higher educational attainment appear less likely to age in place. The influence of socioeconomic position, education and social resources differs by gender and race/ethnicity, indicating intersectional effects across social dimensions.
CONCLUSIONS: Social dimensions influence the ability to age in place in OECD settings, likely due to health inequalities across the lifespan, disparities in access to healthcare and support services, and different preferences regarding ageing in place. Our results can inform the development of policies and programmes to equitably support ageing in place in diverse populations.

Iron supplementation is commonly recommended for the prevention and treatment of maternal iron deficiency (ID) or iron deficiency anemia (IDA). However, the impacts of prophylactic of therapeutic prenatal iron supplementation on child neurodevelopment in upper middle-income (UMI) and high-income countries (HICs), where broad nutritional deficiencies are less common, are unclear. To investigate this, we conducted a systematic review, searching four databases (Medline, CINAHL, EMBASE, Cochrane Library) through 1 May 2023. Randomized controlled trials (RCTs) assessing oral or intravenous iron supplementation in pregnant women reporting on child neurodevelopment (primary outcome: age-standardized cognitive scores) were eligible. We included three RCTs (five publications) from two HICs (Spain and Australia) (N = 935 children; N = 1397 mothers). Due to clinical heterogeneity of the RCTs, meta-analyses were not appropriate; findings were narratively synthesized. In non-anemic pregnant women, prenatal iron for prevention of IDA resulted in little to no difference in cognition at 40 days post-partum (1 RCT, 503 infants; very low certainty evidence). Similarly, the effect on the intelligence quotient at four years was very uncertain (2 RCTs, 509 children, very low certainty evidence). No RCTs for treatment of ID assessed offspring cognition. The effects on secondary outcomes related to language and motor development, or other measures of cognitive function, were unclear, except for one prevention-focused RCT (302 children), which reported possible harm for children\'s behavioral and emotional functioning at four years. There is no evidence from UMI countries and insufficient evidence from HICs to support or refute benefits or harms of prophylactic or therapeutic prenatal iron supplementation on child neurodevelopment.

BACKGROUND: Economic relief programs are strategies designed to sustain societal welfare and population health during a regional or global scale infectious disease outbreak. While economic relief programmes are considered essential during a regional or global health crisis, there is no clear consensus in the literature about their health and non-health benefits and their impact on promoting equity.
METHODS: We conducted a scoping review, searching eight electronic databases from January 01, 2001, to April 3, 2023, using text words and subject headings for recent pathogens (coronavirus (COVID-19), Ebola, Influenza, Middle East Respiratory Syndrome (MERS), severe acute respiratory syndrome (SARS), HIV, West Nile, and Zika), and economic relief programs; but restricted eligibility to high-income countries and selected diseases due to volume. Title and abstract screening were conducted by trained reviewers and Distiller AI software. Data were extracted in duplicates by two trained reviewers using a pretested form, and key findings were charted using a narrative approach.
RESULTS: We identified 27,263 de-duplicated records, of which 50 were eligible. Included studies were on COVID-19 and Influenza, published between 2014 and 2023. Zero eligible studies were on MERS, SARS, Zika, Ebola, or West Nile Virus. We identified seven program types of which cash transfer (n = 12) and vaccination or testing incentive (n = 9) were most common. Individual-level economic relief programs were reported to have varying degrees of impact on public health measures, and sometimes affected population health outcomes. Expanding paid sick leave programs had the highest number of studies reporting health-related outcomes and positively impacted public health measures (isolation, vaccination uptake) and health outcomes (case counts and the utilization of healthcare services). Equity impact was most often reported for cash transfer programs and incentive for vaccination programs. Positive effects on general well-being and non-health outcomes included improved mental well-being and quality of life, food security, financial resilience, and job security.
CONCLUSIONS: Our findings suggest that individual-level economic relief programs can have significant impacts on public health measures, population health outcomes and equity. As countries prepare for future pandemics, our findings provide evidence to stakeholders to recognize health equity as a fundamental public health goal when designing pandemic preparedness policies.

BACKGROUND: With increasing trend of internet use in all age groups, whether internet use can prevent frailty in middle-aged and older adults remains unclear.
METHODS: Five cohorts, including Health and Retirement Study (HRS), China Health and Retirement Longitudinal Study (CHARLS), the Survey of Health, Ageing and Retirement in Europe (SHARE), English Longitudinal Study of Aging (ELSA), and Mexican Health and Aging Study (MHAS), were used in this study. Internet use, social isolation, and frailty status was assessed using similar questions. The Generalized estimating equations models, random effects meta-analysis, COX regression, and mediation analysis were utilized.
RESULTS: In the multicohort study, a total of 155,695 participants were included in main analysis. The proportion of internet use was varied across countries, ranging from 5.56% in China (CHARLS) to 83.46% in Denmark (SHARE). According to the generalized estimating equations models and meta-analysis, internet use was inversely associated with frailty, with the pooled ORs (95%CIs) of 0.72 (0.67,0.79). The COX regression also showed that participants with internet use had a lower risk of frailty incidence. Additionally, the association was partially mediated by social isolation and slightly pronounced in participants aged 65 and over, male, not working for payment, not married or partnered, not smoking, drinking, and not co-residence with children.
CONCLUSIONS: Our findings highlight the important role of internet use in preventing frailty and recommend more engagements in social communication and activities to avoid social isolation among middle-aged and older adults.

BACKGROUND: Despite ongoing efforts, perinatal morbidity and mortality persist across all settings, imposing a dual burden of clinical and economic strain. Besides, the fragmented nature of economic evidence on perinatal health interventions hinders the formulation of effective health policies. Our review aims to comprehensively and critically assess the economic evidence for such interventions in high-income countries, where the balance of health outcomes and fiscal prudence is paramount.
METHODS: We will conduct a comprehensive search for studies using databases including EconLit (EBSCO), Cost Effectiveness Analysis (CEA) Registry, Medline (Ovid), Embase (Ovid), CINAHL Ultimate (EBSCO), Global Health (Ovid), and PubMed. Furthermore, we will broaden our search to include Google Scholar and conduct snowballing from the final articles included. The search terms will encompass economic evaluation, perinatal health interventions, morbidity and mortality, and high-income countries. We will include full economic evaluations focusing on cost-effectiveness, cost-benefit, cost-utility, and cost-minimisation analyses. We will exclude partial economic evaluations, reports, qualitative studies, conference papers, editorials, and systematic reviews. Date restrictions will limit the review to studies published after 2010 and those in English during the study selection process. We will use the modified Drummond checklist to evaluate the quality of each included study. Our findings will adhere to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) 2020 statement. A summary will include estimated costs, effectiveness, benefits, and the incremental cost-effectiveness ratio (ICER). We also plan to conduct a subgroup analysis. To aid comparability, we will standardise all costs to the United States Dollar, adjusting them to their 2022 value using country-specific consumer price index and purchasing power parity.
BACKGROUND: This systematic review will not involve human participants and requires no ethical approval. We will publish the results in a peer-reviewed journal.
BACKGROUND: We registered our record on PROSPERO (registration #: CRD42023432232).
