Accessibility of and barriers to the use of eye health services in Kumasi Metropolis, Ghana.

BACKGROUND:  There is a high prevalence of vision impairment and blindness in Africa. The poor access to eye health services, among other barriers, has been found to have a considerable effect on the burden of avoidable vision loss and blindness, particularly in low- and middle-income countries. AIM:  To determine the accessibility of and barriers to the utilisation of eye health services in the Kumasi Metropolis of Ghana. SETTING:  A descriptive cross-sectional survey was conducted in the Kumasi Metropolis of the Ashanti Region in Ghana to identify barriers affecting the utilisation of eye health services. METHODS:  Convenience sampling was used to recruit participants visiting the eye clinics at five selected District Municipal Hospitals for the first time. Data were collected by means of questionnaires and analysed using Statistical Package for Social Sciences (SPSS). RESULTS:  Barriers faced by participants when accessing eye health services included distance to the clinic, cost of services, time spent away from work and/or school, self-medication and long waiting periods. CONCLUSION:  The study found that eye care services in the Kumasi Metropolis, Ghana are largely accessible, but underutilised. Improvement of public health education initiatives through engagement with community groups will also enhance uptake at health care facilities.Contribution: Underutilisation of health services in the Metropolis has been identified in the study and must be addressed by health managers in various sectors. Accessibility is relatively good but can further be improved especially for the elderly to be able to utilise health care services with ease.

Acesso a serviço de saúde e reabilitação auditiva de adultos e idosos durante o período inicial da pandemia COVID-19 no Brasil / Access to health service and hearing rehabilitation for adult and older adults during the initial period of the COVID-19 pandemic in Brazil / Acceso a servicios de salud yrehabilitación auditiva para adultos y ancianos durante el período inicial de la pandemia COVID-19 en Brasil

Introdução: A perda auditiva é uma deficiência comum na população mundial e contribui para dificuldade na comunicação verbal e redução da qualidade de vida, evidenciando a importância da identificação precoce, reabilitação e acompanhamento audiológico dessa deficiência para mitigar suas consequências. Durante a pandemia da COVID-19, as medidas restritivas diminuíram a capacidade de atendimento dos serviços de saúde auditiva e dificultaram a busca de auxílio para resolver problemas relacionados à adaptação aos dispositivos eletrônicos de amplificação sonora (DAES), sendo uma barreira no processo de reabilitação da perda auditiva. Objetivo: Caracterizar os usuários de DEAS e o processo inicial de reabilitação auditiva de adultos e idosos e verificar fatores associados ao retorno para a consulta de monitoramento auditivo durante o período inicial da pandemia da COVID-19.Métodos: Estudo observacional transversal com usuários adultos e idosos de um serviço ambulatorial de saúde auditiva com retorno para consulta de monitoramento auditivo agendada no período inicial da implementação das medidas restritivas da pandemia da COVID-19 no Brasil. Resultados: A maioria dos participantes conseguiu retornou para a consulta de monitoramento auditivo, sendo eles em sua maioria idosos, do sexo feminino e vacinados contra a COVID-19. Houve maior prevalência de adaptação adequada aos DAES. Não houve associação estatística entre as variáveis relacionadas à adaptação aos DAES, COVID-19 e saúde mental e o retorno à consulta de monitoramento auditivo. Conclusão: Os fatores relacionados à adaptação aos DAES, à COVID-19 ou à saúde mental não influenciaram o retorno à consulta de monitoramento auditivo na presente pesquisa. (AU)

Introduction: Hearing loss is a common disability in the world population and contributes to difficulty in verbal communication and reduced quality of life, highlighting the importance of early identification, rehabilitation and audiological monitoring of this disability to mitigate its consequences. During the COVID-19 pandemic, restrictive measures reduced the service capacity of hearing health services and made it difficult to seek help to solve problems related to adaptation to personal sound amplification products (PSAPs), being a barrier in the rehabilitation process of hearing loss. Aim: To characterize PSAPs users and the initial hearing rehabilitation process for adults and elderly people and verify the factors associated with the return to hearing monitoring consultations in the initial period of the COVID-19 pandemic. Methods: Cross-sectional observational study with adults and elderly people: elderly users of an outpatient hearing health service who return for a scheduled hearing monitoring consultation in the initial period of the implementation of restrictive measures of the COVID-19 pandemic in Brazil. Results: Most participants were able to return to the hearing monitoring clinic, the majority of whom were elderly, female and vaccinated against COVID-19. There was a higher prevalence of adequate adaptation to the PSAPs. There was no statistical association between variables related to adaptation to PSAPs, COVID-19 and mental health and return to hearing monitoring consultation. Conclusion: Factors related to adaptation to PSAPs, COVID-19 or mental health did not influence the return to hearing monitoring consultation in the present investigation. (AU)

Impact of health insurance on the use of oral health services in the Peruvian population 2015-2019.

BACKGROUND: The high treatment cost of oral diseases is a barrier for accessing oral health services (OHS), particularly in low-income countries. Therefore, this study aimed to evaluate the impact of health insurance on the use of OHS in the Peruvian population from 2015 to 2019. METHODS: We conducted a prospective, longitudinal study of secondary data using the National Household Survey (ENAHO) 2015-2019 panel databases, which collected information from the same participants during each of the five years. The dependent variable was the use of OHS in the three months prior to the survey (yes/no). The independent variable was health insurance affiliation (four years or less/all five years). Both were measured by survey questions. Generalized estimating equation (GEE) Poisson regression models with robust standard errors were used to estimate the relative risk (RR) associated with use of OHS. RESULTS: We included 4064 individuals distributed in 1847 households, who responded to the survey during each of the five years. The adjusted GEE model showed that those who had health insurance during all five years without interruption were more likely to attend OHS than those who had insurance for four years or less (adjusted relative risk [aRR]: 1.30; 95%CI: 1.13-1.50). In addition, we carried out a sensitivity analysis by recategorizing the independent variable into three categories (never/some years/ all five years), which also showed (aRR: 1.45; 95%CI: 1.11-1.89) that participants with health insurance during all five years were more likely to have used OHS than those who never had insurance. CONCLUSION: Therefore, in the Peruvian context, health insurance affiliation was associated with greater use of OHS. The panel data used derives from a subsample of consecutive nationally representative samples, which may have led to a loss of representativeness. Furthermore, the data was collected between 2015 and 2019, prior to the onset of the COVID-19 pandemic, and insurance conditions may have changed.

Centering Digital Health Equity During Technology Innovation: Protocol for a Comprehensive Scoping Review of Evidence-Based Tools and Approaches.

BACKGROUND: In the rush to develop health technologies for the COVID-19 pandemic, the unintended consequence of digital health inequity or the inability of priority communities to access, use, and receive equal benefits from digital health technologies was not well examined. OBJECTIVE: This scoping review will examine tools and approaches that can be used during digital technology innovation to improve equitable inclusion of priority communities in the development of digital health technologies. The results from this study will provide actionable insights for professionals in health care, health informatics, digital health, and technology development to proactively center equity during innovation. METHODS: Based on the Arksey and O'Malley framework, this scoping review will consider priority communities' equitable involvement in digital technology innovation. Bibliographic databases in health, medicine, computing, and information sciences will be searched. Retrieved citations will be double screened against the inclusion and exclusion criteria using Covidence (Veritas Health Innovation). Data will be charted using a tailored extraction tool and mapped to a digital health innovation pathway defined by the Centre for eHealth Research roadmap for eHealth technologies. An accompanying narrative synthesis will describe the outcomes in relation to the review's objectives. RESULTS: This scoping review is currently in progress. The search of databases and other sources returned a total of 4868 records. After the initial screening of titles and abstracts, 426 studies are undergoing dual full-text review. We are aiming to complete the full-text review stage by May 30, 2024, data extraction in October 2024, and subsequent synthesis in December 2024. Funding was received on October 1, 2023, from the Centre for Health Equity Incubator Grant Scheme, University of Melbourne, Australia. CONCLUSIONS: This paper will identify and recommend a series of validated tools and approaches that can be used by health care stakeholders and IT developers to produce equitable digital health technology across the Centre for eHealth Research roadmap. Identified evidence gaps, possible implications, and further research will be discussed. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/53855.

Accessibility to palliative care services in Colombia: an analysis of geographic disparities.

OBJECTIVES: Due to the increase in the prevalence of non-communicable diseases and the Colombian demographic transition, the necessity of palliative care has arisen. This study used accessibility and coverage indicators to measure the geographic barriers to palliative care. METHODS: Population-based observational study focused on urban areas and adult population from Colombia, which uses three measurements of geographic accessibility to services: a) density of palliative care services per 100,000 inhabitants, b) analysis of geographic distribution by territorial nodes of the country, and c) spatial analysis of palliative care services using Voronoi diagrams. ArcGIS Pro software was used to map services' locations and identify geographic disparities. RESULTS: A total of 504 palliative care services were identified, of which 77% were primary health care services. The density of palliative care services in Colombia is 1.8 primary care services per 100,000 inhabitants and 0.4 specialized services per 100,000 inhabitants. The average palliative care coverage is 41%, two regions of the country have a coverage below 30%. Twenty-eight percent of the services provide care for a population greater than 50,000 inhabitants within their coverage area, exceeding the acceptable limit by international standards. CONCLUSIONS: Palliative care services are concentrated in three main regions (Bogotá D.C., the Center, and the Caribbean) and are limited in the Orinoquia and Amazonia nodes. Density of specialized palliative care services is extremely low and there are regions without palliative services for adults with palliative needs.

Spatial accessibility and inequality analysis of rabies-exposed patients to rabies post-exposure prophylaxis clinics in Guangzhou City, China.

BACKGROUND: The incidence of rabies exposure is high and increasing in China, leading to an urgent demand of rabies post-exposure prophylaxis (PEP) clinics for the injured. However, the spatial accessibility and inequality of rabies-exposed patients to rabies PEP clinics is less known in China. METHODS: Based on rabies exposure data, PEP clinic data, and resident travel origin-destination (OD) matrix data in Guangzhou City, China, we first described the incidence of rabies exposure in Guangzhou from 2020 to 2022. Then, the Gaussian two-step floating catchment area method (2SFCA) was used to analyze the spatial accessibility of rabies-exposed patients to rabies PEP clinics in Guangzhou, and the Gini coefficient and Moran's I statistics were utilized to evaluate the inequality and clustering of accessibility scores. RESULTS: From 2020 to 2022, a total of 524,160 cases of rabies exposure were reported in Guangzhou, and the incidence showed a significant increasing trend, with an average annual incidence of 932.0/100,000. Spatial accessibility analysis revealed that the overall spatial accessibility scores for three scenarios (threshold of driving duration [d0] = 30 min, 45 min, and 60 min) were 0.30 (95% CI: 0.07, 0.87), 0.28 (95% CI: 0.11, 0.53) and 0.28 (95% CI: 0.14, 0.44), respectively. Conghua, Huangpu, Zengcheng and Nansha districts had the higher accessibility scores, while Haizhu, Liwan, and Yuexiu districts exhibited lower spatial accessibility scores. The Gini coefficient and Moran's I statistics showed that there were certain inequality and clustering in the accessibility to rabies PEP clinics in Guangzhou. CONCLUSIONS: This study clarifies the heterogeneity of spatial accessibility to rabies PEP clinics, and provide valuable insights for resource allocation to achieve the WHO target of zero human dog-mediated rabies deaths by 2030.

Final assessment of the COVID-19 pandemic impact between the different social and economic strata population of the city of Buenos Aires.

Background: During the pandemic, epidemiological communications reported an estimation of excess deaths. However, the final calculation requires a detailed analysis. The study aim was to ascertain the number and distribution of COVID-19 fatalities among various socio-economic strata in a large, moderate to low-income city. Study design: Observational time series analysis in a large city, treated as a natural experiment. Methods: Analysis of death certificates, demographic data, and health system records of positive RT-PCR COVID-19 tests from 2015 to 2021, categorizing by age, sex, and place of residence. The study measured the pandemic's impact on mortality, including COVID and non-COVID deaths, using corrected Poisson regression models for different demographics and assessing socio-economic status impact via ecological community-level analysis. Results: Compared to the pre-pandemic period (2015-2019, IRR = 1.00), the sex- and age-adjusted rate of all-cause death increased significantly during the pandemic (2020-2021) IRR = 1.109 [1.054-1.167], p < 0.0001. This was observed in both males (IRR = 1.158 [1.1-1.219], p < 0.0001) and females (IRR = 1.068 [1.016-1.124], p = 0.01). There was no observed effect of the pandemic on the historical trend in the progressive reduction of mortality in people under 35 years of age. The increase in deaths was at the expense of COVID (+11,175 deaths) and cardiovascular causes (IRR = 1.114 [1.020-1.217] p = 0.017). During the pandemic, there was a significant increase in deaths at home (IRR = 1.219 [1197-1.242], p < 0.0001), especially in people dying of cardiovascular causes (IRR = 1.391 [1.360-1.422], p < 0.0001). The increase in the adjusted mortality rate during the pandemic was socially conditioned. Conclusions: The pandemic not only led to increased COVID-19 mortality but also heightened fatalities from non-COVID causes, reflecting a potential bias in healthcare resource allocation towards SARS-CoV-2 at the expense of chronic pathologies care.

Infant Feeding Support for Pregnant and Postpartum Parents With Intellectual and Developmental Disabilities: Perspectives of WIC Staff.

OBJECTIVE: To describe the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) staff experiences, perceptions, and training needs surrounding the provision of infant feeding support for parents with intellectual and developmental disabilities (IDD). METHODS: We conducted in-depth semistructured interviews between October and November 2021 with Maryland WIC staff (N = 10) who provide infant feeding counseling and support. We analyzed interviews using conventional content analysis. RESULTS: Three themes were identified: identifying and documenting IDD, facilitating effective communication and infant feeding education, and assessing WIC staff competence and readiness. CONCLUSIONS AND IMPLICATIONS: The interviews suggested the need to explore the risks and benefits of routine and compassionate processes for identifying and documenting disability, create accessible teaching materials that facilitate understanding and engagement, and educate and train staff to provide tailored support in WIC. Engaging parents with IDD to better understand their perspectives and experiences should guide future efforts to improve inclusivity and accessibility.

"Being ill was the easy part": exploring cancer survivors' reactions to perceived challenges in engaging with primary healthcare.

PURPOSE: Cancer survivors experience barriers to primary healthcare (PHC) services. The aim was to explore reactions to and opinions about perceived challenges associated with PHC access and quality among cancer survivors in Sweden, including how they have acted to adapt to challenges. METHODS: Five semi-structured focus group interviews were conducted with cancer survivors (n = 20) from Skåne, Sweden, diagnosed with breast, prostate, lung, or colorectal cancer or malignant melanoma. Focus groups were mixed in regard to diagnosis. Data were analysed using a descriptive template analysis approach. RESULTS: In light of perceived challenges associated with access to adequate PHC, participants experienced that they had been forced to work hard to achieve functioning PHC contacts. The demands for self-sufficiency were associated with negative feelings such as loneliness and worry. Participants believed that cancer survivors who lack the ability to express themselves, or sufficient drive, risk missing out on necessary care due to the necessity of being an active patient. CONCLUSIONS: The findings highlight negative patient experiences. They have implications for the organization of care for cancer survivors as they indicate a need for more efficient post-treatment coordination between cancer specialist care and PHC providers, as well as increased support for patients leaving primary cancer treatment.

Equity in the Setting of Heart Failure Diagnosis: An Analysis of Differences Between and Within Clinician Practices.

BACKGROUND: Timely heart failure (HF) diagnosis can lead to earlier intervention and reduced morbidity. Among historically marginalized patients, new-onset HF diagnosis is more likely to occur in acute care settings (emergency department or inpatient hospitalization) than outpatient settings. Whether inequity within outpatient clinician practices affects diagnosis settings is unknown. METHODS: We determined the setting of incident HF diagnosis among Medicare fee-for-service beneficiaries between 2013 and 2017. We identified sociodemographic and medical characteristics associated with HF diagnosis in the acute care setting. Within each outpatient clinician practice, we compared acute care diagnosis rates across sociodemographic characteristics: female versus male sex, non-Hispanic White versus other racial and ethnic groups, and dual Medicare-Medicaid eligible (a surrogate for low income) versus nondual-eligible patients. Based on within-practice differences in acute diagnosis rates, we stratified clinician practices by equity (high, intermediate, and low) and compared clinician practice characteristics. RESULTS: Among 315 439 Medicare patients with incident HF, 173 121 (54.9%) were first diagnosed in acute care settings. Higher adjusted acute care diagnosis rates were associated with female sex (6.4% [95% CI, 6.1%-6.8%]), American Indian (3.6% [95% CI, 1.1%-6.1%]) race, and dual eligibility (4.1% [95% CI, 3.7%-4.5%]). These differences persisted within clinician practices. With clinician practice adjustment, dual-eligible patients had a 4.9% (95% CI, 4.5%-5.4%) greater acute care diagnosis rate than nondual-eligible patients. Clinician practices with greater equity across dual eligibility also had greater equity across sex and race and ethnicity and were more likely to be composed of predominantly primary care clinicians. CONCLUSIONS: Differences in HF diagnosis rates in the acute care setting between and within clinician practices highlight an opportunity to improve equity in diagnosing historically marginalized patients.

Collaborations and Networks Within Communities for Improved Utilization of Primary Healthcare Centers: On the Road to Universal Health Coverage.

Objectives: Community involvement depends on the level of linked and targeted activities for health by community members. This study examines the collaborations employed within communities to ensure sustainable access and improved use of healthcare in the community. Methods: This study was conducted in rural and urban local government areas in Anambra, Kano, and Akwa-Ibom, Nigeria. About 90 in-depth interviews and 12 focus group discussions were conducted with community stakeholders and service users. The findings were transcribed and coded via thematic analysis, guided by the Expanded Health Systems framework. Results: Various horizontal collaborations in communities foster increased use of PHC services; promoting community health. Major horizontal collaborations in these communities were community-led, primary health facility-led, and Individual-led collaborations. Their actions revolved around advocacy, building and renovating PHC centers, equipping facilities, and sensitization to educate community members on the need to utilize services at PHC centers. Conclusion: Strategic involvements and collaborations of local actors within communities give rise to improvements in the utilization of primary healthcare centres, reportedly resulting in improved access to PHC healthcare services for community members.

Impact of national drug price negotiation policy on the accessibility and utilization of PCSK9 inhibitors in China: an interrupted time series analysis.

BACKGROUND: PCSK9 inhibitors are a novel class of lipid-lowering drugs that have demonstrated favorable efficacy and safety. Evolocumab and alirocumab have been added to China's National Reimbursement Drug List through the National Drug Price Negotiation (NDPN) policy. This study aims to evaluate the impact of the NDPN policy on the utilization and accessibility of these two PCSK9 inhibitors. METHODS: The procurement data of evolocumab and alirocumab were collected from 1,519 hospitals between January 2021 and December 2022. We determined the monthly availability, utilization, cost per daily defined dose (DDDc), and affordability of the two medicines. Single-group interrupted time series (ITS) analysis was performed to assess the impact of the NDPN policy on each drug, and multiple-group ITS analysis was performed to compare the differences between them. RESULTS: The NDPN policy led to a significant and sudden increase in the availability and utilization of PCSK9 inhibitors, along with a decrease in their DDDc. In the year following the policy implementation, there was an increase in the availability, utilization, and spending, and the DDDc remained stable. The affordability of PCSK9 inhibitors in China have been significantly improved, with a 92.97% reduction in out-of-pocket costs. The availability of both PCSK9 inhibitors was similar, and the DDDc of alirocumab was only $0.23 higher after the intervention. The market share of evolocumab consistently exceeded that of alirocumab. Regional disparities in utilization were observed, with higher utilization in the eastern region and a correlation with per capita disposable income. CONCLUSIONS: The NDPN policy has successfully improved the accessibility and utilization of PCSK9 inhibitors in China. However, regional disparities in utilization indicate the need for further interventions to ensure equitable medicine access.

Toxicokinetics of selenate in earthworm sub-tissues and potential bio-accessibility assessment of earthworm-derived selenium.

Selenium (Se) pollution is mainly caused by anthropogenic activities, and the resulting biosecurity concerns have garnered significant attention in recent years. Using one-compartmental toxicokinetic (TK) modelling, this study explored the kinetic absorption, sub-tissue distribution, and elimination processes of the main Se species (selenate, Se(VI)) in the cultivated aerobic soil of the earthworm Eisenia fetida. The bio-accessibility of earthworm-derived Se was assessed using an in vitro simulated gastrointestinal digestion test to evaluate its potential trophic risk. The results demonstrated that Se accumulated in the pre-clitellum (PC) and total tissues (TT) of earthworms in a time- and dose-dependent manner. The highest Se levels in the PC, post-clitellum (PoC), and TT were 70.54, 57.93, and 64.26 mg/kg during the uptake phase, respectively. The kinetic Se contents in the earthworms PC and TT were consistent with the TK model but not with PoC. The earthworm TT exhibited a faster uptake (Kus = 0.83-1.02 mg/kg/day) and elimination rate of Se (Kee = 0.044-0.049 mg/kg/day), as well as a shorter half-life time (LT1/2 = 15.88-14.22 days) than PC at low soil Se levels (≤5 mg/kg). Conversely, the opposite trend was observed with higher Se concentrations (10 and 20 mg/kg). These results are likely attributable to the tissue specificity and concentration of the toxicant. Earthworms PC and TT exhibited a higher kinetic Se accumulation factor (BAFk) than steady-state BAF (BAFss), with values ranging from 8 to 24 and 3-13, respectively. Furthermore, the bio-accessibility of earthworm-derived Se to poultry ranged from 66.25 % to 84.35 %. As earthworms are at the bottom of the terrestrial food chain, the high bio-accessibility of earthworm-derived Se poses a potential risk to predators. This study offers data support and a theoretical foundation for understanding the biological footprint of soil Se and its toxicological impacts and ecological hazards.

Identification, spatial distribution, and associated factors of urban protected areas in China.

The increasing proximity between protected areas (PAs) and urban areas, which can lead to urban protected areas (UPAs), is now commonplace. Use of Euclidean distance to measure the distance between PAs and cities has not correctly portrayed the spatial relationship between PAs and cities. We devised an isochronous circle model to accurately measure the distance between 2706 national PAs in 5 categories and 2844 cities in China based on human accessibility to identify urban human activity-influenced protected areas (UHAIPAs) and to quantitatively analyze their distribution patterns and relationships with China's economy, population distribution patterns, and urban development indicators. Most of the PAs in China were established near cities. Of 2746 PAs in China, 18.35% (n = 504) became UPAs, and 58.27% (n = 1600), 16.72% (n = 459), and 3.31% (n = 91) of PAs were within 0-30, 30-60, and 60-90 min, respectively. Both UPAs and UHAIPAs in China in general exhibited obvious spatial aggregation characteristics (e.g., wetland parks and scenic areas), and there was a significant spatial dependence effect among characteristics. The degree of spatial distribution and aggregation of UPAs was correlated with 16 indicators across urban economic development, urban natural substrate, and urban policy support factors. Based on the results of our study, we call for various governments and scholars to focus on areas where wetland parks and PAs overlap with urban boundaries. It is important to emphasize the potential link between the development of agriculture, forestry, livestock and fisheries industries, and UPAs. Overall, we believe that examining the accessibility of PAs can more accurately measure the distance between PAs and cities, and more realistically reflect the possible impacts of urban human activities on PAs, which is helpful for strengthening the conservation and management of PAs.

Identificación, distribución espacial y factores asociados de las áreas urbanas protegidas en China Resumen La creciente proximidad entre las áreas protegidas (AP) y las áreas urbanas, que puede derivar en áreas urbanas protegidas (AUP), es muy común hoy en día. La distancia euclidiana no ha representado correctamente la distancia entre las AP y las ciudades. Por lo anterior, diseñamos un modelo de círculo isócrono para medir con certeza la distancia entre 2706 AP nacionales en cinco categorías y 2844 ciudades de China con base en la accesibilidad humana para identificar las áreas urbanas protegidas con influencia de actividad humana (AUPIAH). También lo usamos para analizar cuantitativamente los patrones de distribución y su relación con la economía china, los patrones de distribución poblacional y los indicadores de desarrollo urbano. La mayoría de las AP en China están establecidas cerca de las ciudades. De las 2746 AP, el 18.35% (n = 504) se convirtieron en AUP y el 58.27% (n = 1600), 16.72% (n = 459) y 3.31% (n = 91) se encontraban de 0­30 minutos, 30­60 y de 60­90 minutos de una ciudad, respectivamente. Tanto las AUP y las AUPIAH exhibieron características obvias de agregación espacial (p. ej.: parques de humedales y áreas escénicas) y hubo un efecto significativo de dependencia espacial entre dichas características. El nivel de distribución y agregación espacial de las AUP tuvo correlación con 16 indicadores de desarrollo económico urbano, sustrato natural urbano y factores de apoyo para las políticas urbanas. Con base en los resultados de nuestro estudio, hacemos un llamado para que diferentes gobiernos y académicos se enfoquen en las áreas en donde se traslapan las AP y los parques de humedales con los límites urbanos. Es importante resaltar la conexión potencial entre el desarrollo de la agricultura, silvicultura, ganadería y pesquería y las AUP. En general, consideramos que analizar la accesibilidad de las AP puede medir de forma más certera la distancia entre las AP y las ciudades, además de que refleja de forma más realista el posible impacto de las actividades humanas sobre las AP, lo cual es útil para fortalecer la conservación y gestión de las AP.

Bio-accessibility and bio-availability evaluation of each arsenic species existing in various edible seaweeds in vitro and in vivo for arsenic risk assessment.

Seaweeds consumption is one of main internal exposure sources of arsenic for human. However, the absence of representative bio-availabilities of arsenic species makes the accurate assessment of arsenic health risk originating from seaweeds consumption impossible. Herein, the arsenic species in various seaweeds collected from Fujian of China were investigated, and the bio-accessibilities/bio-availabilities of arsenic species existing in seaweeds were evaluated in vitro and in vivo. Results revealed that in vitro bio-availabilities of arsenic species presenting in seaweeds, which obtained with Caco-2 cells, were lower than those of pure arsenic standards, and varied with order of inorganic arsenic (iAs) > dimethylarsinic acid (DMA) ≈ arsenobetaine (AsB) > arsenosugars. During gastrointestinal digestion of mice, As5+ was partly methylated into monomethylarsonic acid (MMA) and DMA, which makes the in vivo bioavailability of iAs (⁓31.8 %) obtained with mouse metabolic experiment is much higher than its in vitro bio-availability (⁓10.3 %). The in vivo bio-availabilities of DMA and total arsenic (tAs) are similar to their in vitro bio-availabilities. As the dominant arsenic species in most seaweeds, arsenosugars have an ⁓0.0 % of in vivo bioavailability and only a ⁓3.7 % of in vitro bioavailability. The simulated calculation of target hazard quotient (THQ) and target cancer risk (TR) revealed that the arsenic risk originating from seaweeds was greatly degraded by taking into consideration of arsenic species and bio-availabilities, and all seaweeds collected from Fujian are safety for consumption. The simulated calculation also revealed that arsenic risk of seaweeds can be also more accurately assessed based on tAs together with bioavailability, which provides a simple but accurate and protective method for the risk assessment of arsenic originating from seaweeds. Our work provides the possible representative bio-availabilities of arsenic species presenting in seaweeds for accurately assessing arsenic risk of seaweeds, and novel insights into the bio-availabilities of arsenic in animal.

Differences in Receipt of Time Alone with Healthcare Providers Among US Youth Ages 12-17.

BACKGROUND: Time to meet privately with a health care provider can support optimal adolescent health, but numerous barriers exist to implementing this practice routinely. METHODS: We examined parent reports on their children aged 12 to 17 from a nationally generalizable sample to quantify the presence of time alone with health care providers at the state and national level, as well as socio-contextual correlates using logistic regression analysis. RESULTS: We estimated that only 1 in 2 adolescents had a confidential discussion at their last medical visit. Certain child, family, and health care factors were associated with lower likelihood for having had confidential discussions. Specifically, adolescents who were Asian; did not have mental, emotional, or behavioral problems; were uninsured; or lived in households with parents who were immigrants, less educated, or did not speak English had significantly lower odds for having had time alone compared with referent groups. DISCUSSION: Clinical and structural efforts to rectify these gaps may assist a broader share of youth in benefiting from private health care discussions with providers.

Evaluating the spatial accessibility and spatial layout optimization of HIV/AIDS healthcare services in Shandong Province, China.

Improving access to HIV/AIDS healthcare services is of great concern to government and policymakers striving to strengthen overall public health. How to reasonably allocate HIV/AIDS healthcare resources and maximize the equality of access to healthcare services across subdistrict areas has become an urgent problem to be solved. However, there is limited research on this topic in China. It is necessary to evaluate spatial accessibility to improve the accessibility and equity of HIV/AIDS healthcare services. In this study, the improved multi-modal two-step floating catchment area (2SFCA) and inverted 2SFCA (i2SFCA) methods are used to measure the spatial accessibility of HIV/AIDS healthcare services and the crowdedness of the healthcare sites in Shandong Province, China. Then, the theoretical supply and the optimal spatial distribution of resources are calculated and visualized by minimizing the accessibility gaps between demand locations. This study showed that the spatial accessibility of HIV/AIDS service resources in Shandong Province was concentrated and unevenly distributed, and the accessibility scores in the marginal areas of prefecture-level cities were significantly lower than those in other areas. Regions with a large number of doctors had significantly higher levels of spatial accessibility. The ART accessibility scores in the southwest of Shandong Province were higher than those in other regions. As the travel friction coefficient increased, the accessibility scores formed an approximately circular cluster distribution centered on the healthcare sites in geographical distribution. More ART drugs needed to be supplied in marginal areas and more doctors were needed to work on HIV/AIDS in urban areas to address the spatial distribution imbalance of HIV/AIDS healthcare services. This study profoundly analyzed the spatial accessibility of HIV/AIDS healthcare services and provided essential references for decision-makers. In addition, it gives a significant exploration for achieving the goal of equal access to HIV/AIDS healthcare services in the future.

Diversity, Equity, Inclusion, and Antiracism Research in Physical Therapy over the Last 25 Years: A Scoping Review.

OBJECTIVE: Discussions of the root causes of health disparities and educational inequities often neglect to identify racism as a primary factor. Researchers must take a systems perspective in order to identify the effects of racism and other forms of systemic oppression on health. It is unclear to what extent this perspective exists in the physical therapy research literature. We conducted a scoping review to quantify and describe the volume of research in physical therapy pertaining to diversity, equity, and inclusion that specifically examines race and/or ethnicity and references racism or antiracism. METHODS: A systematic search of PubMed and Scopus databases for articles published between 1997 and 2021 was conducted. Articles were screened to ensure they were focused exclusively or primarily on physical therapy and used diversity, equity, and inclusion terms in the context of personal identity factors. This resulted in 158 relevant articles. Each was tagged with an article type and personal identity factor focus. RESULTS: A majority of the included articles were descriptive/observational in nature. The included articles explored various personal identity factors, with race and ethnicity being the most common focus followed by culture, disability, and socioeconomic status. A small proportion of articles explicitly discussed racism or antiracism. CONCLUSION: These findings highlight the need in physical therapy research for greater attention to racism as a fundamental cause of health disparities and educational inequities. Addressing this gap is crucial for promoting diversity, equity, and inclusion within the field and ultimately achieving optimal health outcomes for marginalized populations. IMPACT: Including consideration of racism and other forms of systemic oppression in the motivation, design, and interpretation of research in physical therapy will help to make more visible the root causes of inequity and improve our ability to develop effective, multi-level interventions.

Variables affecting new drug prices in South Korea's pricing system.

Objective: The price of pharmaceuticals is important from the economic and industrial perspectives but as well as patients' access to treatment. This study aimed to analyze the variables affecting the prices of new drugs in South Korea's pricing system. Methods: Data on 192 new drugs listed in South Korea from 2012 to 2022 were collected from the official website of the Health Insurance Review and Assessment Service. The independent variables included drugs for severe diseases, alternatives, number of patients, number of advanced 7 countries listed, budget impact, and listing period. The dependent variables included annual treatment cost and the price ratio to the advanced 7 country's average adjusted price. Descriptive statistics of variables, linear correlations between quantitative independent and dependent variables, and associations between independent and dependent variables were analyzed. Results: The mean annual treatment cost and price ratio to the advanced 7 country's average adjusted price were higher for drugs for severe diseases and those with no alternatives. Annual treatment cost and price ratio to the advanced 7 country's average adjusted price were negatively correlated with the number of patients and positively correlated with the number of advanced 7 countries listed. Annual treatment cost was affected by the variables drugs for severe diseases, alternatives, number of patients, number of advanced 7 countries listed, and budget impact. The price ratio to the advanced 7 country's average adjusted price was affected by drugs for severe diseases, alternatives, and the number of patients. Conclusion: This study revealed the effect of different variables on the prices of new drugs in South Korea, allowing for the development of a more effective assessment system to evaluate the prices of new drugs while ensuring profitability for pharmaceutical companies, sustainability of public insurance, and accessibility to drugs by patients.
