Identification of Neighborhood Hotspots via the Cumulative Hazard Index: Results From a Community-Partnered Low-Cost Sensor Deployment.

The Strathcona neighborhood in Vancouver is particularly vulnerable to environmental injustice due to its close proximity to the Port of Vancouver, and a high proportion of Indigenous and low-income households. Furthermore, local sources of air pollutants (e.g., roadways) can contribute to small-scale variations within communities. The aim of this study was to assess hyperlocal air quality patterns (intra-neighborhood variability) and compare them to average Vancouver concentrations (inter-neighborhood variability) to identify possible disparities in air pollution exposure for the Strathcona community. Between April and August 2022, 11 low-cost sensors (LCS) were deployed within the neighborhood to measure PM2.5, NO2, and O3 concentrations. The collected 15-min concentrations were down-averaged to daily concentrations and compared to greater Vancouver region concentrations to quantify the exposures faced by the community relative to the rest of the region. Concentrations were also estimated at every 25m grid within the neighborhood to quantify the distribution of air pollution within the community. Using population information from census data, cumulative hazard indices (CHIs) were computed for every dissemination block. We found that although PM2.5 concentrations in the neighborhood were lower than regional Vancouver averages, daily NO2 concentrations and summer O3 concentrations were consistently higher. Additionally, although CHIs varied daily, we found that CHIs were consistently higher in areas with high commercial activity. As such, estimating CHI for dissemination blocks was useful in identifying hotspots and potential areas of concern within the neighborhood. This information can collectively assist the community in their advocacy efforts.

Assessing Teachers’ Dispositions Towards Culturally Responsive Pedagogy in Northwest Arkansas High Schools

Culturally responsive pedagogy (CRP) entails the use of cultural knowledge, prior experiences, and learning styles of ethnically and culturally diverse students to make instruction more relevant and effective for them. Furthermore, practices within this pedagogy are validating, inclusive, emancipatory, and ethical, and help diverse students succeed academically while maintaining their cultural identity. Numerous studies have indicated that using culturally responsive pedagogy increases student academic achievement, sense of self, and emotional well-being (Ladson-Billings, 1995a; Gay, 2018). Considering the varying degrees of cultural and linguistic diversity in Northwest Arkansas (NWA) schools and the lack of reported professional development relating to CRP, this study aimed to examine NWA secondary teachers’ dispositions (values, attitudes, and beliefs) toward culturally responsive pedagogical practices. Employing a mixed methods survey research design, the study integrated self-reported Likert scale ratings and open-ended questions for a more in-depth understanding of teachers' challenges while incorporating CRP into their classrooms. This study presents the online survey results of 131 teachers from 9-12 grades from various regional districts. Findings indicate that NWA secondary teachers report having positive perceptions toward culturally responsive pedagogical practices. Further analysis also suggests factors, such as subject area taught and years of teaching experience, that may impact teacher dispositions. These findings are significant because they indicate potential areas of concern regarding equitable teaching relevant to teacher preparation, training, and support for CRP. They can be used to develop more meaningful, tangible, and supportive professional development. These results could also impact the decisions made by school administrators regarding matters related to CRP, affecting both teachers and the overall school culture.

"This can certainly work…": stakeholder perspectives of the feasibility of a caregiver-led training program for caregivers of children with cerebral palsy in a rural setting in Malawi.

Caregiver training is a key component of rehabilitation for children with complex lifelong disabilities such as cerebral palsy. However critical shortages of therapists in low- and middle-income countries like Malawi, reduce access to therapy. Introducing expert caregivers to assist with the provision of basic training on the condition for fellow caregivers offers a potential solution. However, there is a paucity of evidence regarding the implementation of such strategies in low-resource settings. The aim of this study was to explore perspectives of stakeholders regarding the feasibility of implementing a caregiver-led and delivered training program for caregivers of children with cerebral palsy in Malawi. Over 5 days in January 2023, a caregiver-led training program, the "Malamulele Onward Carer-to-Carer Training Program," was conducted in Blantyre, Malawi. A South African master trainer traveled to Malawi and delivered the program to potential stakeholders including caregivers of children with cerebral palsy; physiotherapists; and community-based organization representatives. Stakeholder perspectives regarding the acceptability, demand, practicality and adaptation of the program were obtained through a combination of focus group discussions, in-depth interviews, and daily field notes. Data from the focus group discussions and in-depth interviews were analyzed using thematic analysis. The caregiver-led training program was deemed acceptable despite two areas identified as potential areas of concern; that the expert caregivers may cross practice boundaries and that their fellow caregivers may look down upon them. A demand for this program was expressed because of perceived relative advantages and relevance to caregiver needs. Participants indicated that the intervention could be easily delivered using local materials, absorbed and supported by existing community structures. A caregiver-led training program offers an innovative way of supporting caregivers of children with complex disabilities such as cerebral palsy in low-resource settings. The stakeholder engagement demonstrated the positive perspectives of all stakeholders. The areas for modification and adaptation highlighted by the stakeholders will be useful in strengthening the implementation of the program in Malawi.

Forest Resource Quality and Human Activity Intensity Change and Spatial Autocorrelation Analysis in Yulin City, China

With the rapid development of society and the economy, human activities are increasing, which often brings potential threats such as a decline in forest resource quality and ecological function. In order to investigate the change in forest resource quality and human activity intensity, this study constructed a calculation model for a forest resource quality index and a human activity intensity index and conducted a quantitative analysis of the temporal and spatial changes in forest resource quality and human activity intensity in Yulin City based on sub-compartment data in 2017 and 2020. By combining spatial autocorrelation analysis, the changes in human activity intensity and spatial forest resource quality were explored, and key areas such as the prominent contradictions between humans and the land were superimposed and coupled as potential areas of concern. The results show the following: From 2017 to 2020, the forest resource quality in Yulin City improved as a whole, especially in Zizhou County, but there were increases and decreases in other regions. Human activity intensity increased as a whole, and the most obvious increase was in Hengshan District. Both the forest resource quality and human activity intensity indexes had spatial aggregation, the differences in forest resource quality between regions were reduced, and human activity intensity showed a trend towards aggregated development. The high–high cluster area for human activity intensity showed a decreasing trend, but it expanded outward in urban areas and other human-gathering areas, such as the surrounding area of Yulin City, Jingbian County, and Shenmu City. The high–high cluster area for forest resource quality showed a shrinking trend. Four specific regions were identified through a spatial coupled superposition analysis to reveal the dynamic relationship between forest resource quality and human activity intensity. The most obvious region was the Yuyang District, where the forest resource quality improved because of a reduction in the pressure of human activities on the natural environment.

Application of machine learning algorithms for localized syringe services program policy implementation – Florida, 2017

Background People who inject drugs (PWID) are at an amplified vulnerability for experiencing a multitude of harms related to their substance use, including viral (e.g. HIV, Hepatitis C) and bacterial infections (e.g. endocarditis). Implementation of evidence-based interventions, such as syringe services programs (SSPs), remains imperative, particularly in locations at an increased risk of HIV outbreaks. This study aims to identify communities in Florida that are high-priority locations for SSP implementation by examining state-level data related to the substance use and overdose crises. Methods State-level surveillance data were aggregated at the ZIP Code Tabulation Area (ZCTA) (n = 983) for 2017. We used confirmed cases of acute HCV infection as a proxy of injection drug use. Least Absolute Selection and Shrinkage Operator (LASSO) regression was used to develop a machine learning model to identify significant indicators of acute HCV infection and high-priority areas for SSP implementation due to their increased vulnerability to an HIV outbreak. Results The final model retained three variables of importance: (1) the number of drug-associated skin and soft tissue infection hospitalizations, (2) the number of chronic HCV infections in people aged 18–39, and 3) the number of drug-associated endocarditis hospitalizations. High-priority SSP implementation locations were identified in both urban and rural communities outside of current Ending the HIV Epidemic counties. Conclusion SSPs are long researched, safe, and effective evidence-based programs that offer a variety of services that reduce disease transmission and assist with combating the overdose crisis. Opportunities to increase services in needed regions across the state now exist in Florida as supported by the expansion of the Infectious Disease Elimination Act of 2019. This study provides details where potential areas of concern may be and highlights regions where future evidence-based harm reduction programs, such as SSPs, would be useful to reduce opioid overdoses and disease transmission among PWID. Key messages The rate of acute HCV in Florida in 2017 was 1.9 per 100,000, nearly twice the national average. Serious injection related infections among PWID are significant indicators of acute HCV infection. High-priority SSP implementation locations in Florida were identified in both urban and rural communities, including those outside of current Ending the HIV Epidemic counties.

A Pilot Study of the Generalizability of Preclinical Entrustment Assessments in Undergraduate Medical Education.

The reproducibility and consistency of assessments of entrustable professional activities (EPAs) in undergraduate medical education (UME) have been identified as potential areas of concern. EPAs were designed to facilitate workplace-based assessments by faculty with a shared mental model of a task who could observe a trainee complete the task multiple times. In UME, trainees are frequently assessed outside the workplace by faculty who only observe a task once. In November 2019, the authors conducted a generalizability study (G-study) to examine the impact of student, faculty, case, and faculty familiarity with the student on the reliability of 162 entrustment assessments completed in a preclerkship environment. Three faculty were recruited to evaluate 18 students completing 3 standardized patient (SP) cases. Faculty familiarity with each student was determined. Decision studies were also completed. Secondary analysis of the relationship between student performance and entrustment (scoring inference) compared average SP checklist scores and entrustment scores. G-study analysis revealed that entrustment assessments struggled to achieve moderate reliability. The student accounted for 30.1% of the variance in entrustment scores with minimal influence from faculty and case, while the relationship between student and faculty accounted for 26.1% of the variance. G-study analysis also revealed a difference in generalizability between assessments by unfamiliar (φ = 0.75) and familiar (φ = 0.27) faculty. Subanalyses showed that entrustment assessments by familiar faculty were moderately correlated to average SP checklist scores (r = 0.44, P < .001), while those by unfamiliar faculty were weakly correlated (r = 0.16, P = .13). While faculty and case had a limited impact on the generalizability of entrustment assessments made outside the workplace in UME, faculty who were familiar with a student's ability had a notable impact on generalizability and potentially on the scoring validity of entrustment assessments, which warrants further study.

Adherence to the American Society for Colposcopy and Cervical Pathology guidelines: an observational study.

ObjectiveThe 2012 American Society for Colposcopy and Cervical Pathology (ASCCP) guidelines were developed to provide guidance regarding cervical pathology and to minimize overtreatment of lesions that may resolve spontaneously. We aimed to evaluate the adherence to these guidelines with referrals for colposcopy at a large academic center and to understand the factors associated with incorrect referrals.MethodsThis retrospective observational study involved women referred to the Virginia Commonwealth University for colposcopy or loop electrosurgical excision procedure from January 2015 to December 2016.ResultsReferral requests from 430 women were reviewed. Among these, 17.4% were discordant with the ASCCP guidelines. The most common discordant colposcopy referrals were low-grade squamous intraepithelial lesions (48%) and atypical squamous cells of undetermined significance (29%). The possibility of incorrect referrals was decreased among high-grade lesions (odds ratio [OR], 0.03), while it was increased in women aged <25 years (OR, 31.6) and in those referred by family medicine (OR, 3.6) or internal medicine (OR, 4.4). Ten patients were referred for cervical cytology results of samples collected from the vaginal cuffs despite hysterectomies performed for benign lesions.ConclusionPatients referred outside of the guidelines were most often women aged <25 years with low-grade lesions. Referrals outside evidence-based guidelines may lead to unnecessary procedures and additional healthcare expenses. Our results help identify the areas for provider education and potential areas of concern regarding the implementation of the 2019 ASCCP guideline updates.

Exploring Nurses' Perception of Antibiotic Use and Resistance: A Qualitative Inquiry.

PurposeQuality use of antibiotics and the development of antibiotic resistance is a global catastrophe. In the conceptual context, the phenomenon is correlated with the healthcare practitioners’ understanding of antibiotic use and resistance. Therefore, the study aimed to highlight nurses’ perception of antibiotic use and resistance at a public healthcare institute in Quetta City, Pakistan.Respondents and MethodsBy using a semi-structured interview guide through the phenomenology-based approach, in-depth, face-to-face interviews were conducted. Nurses practicing at the surgical and medical units of Sandeman Provincial Hospital (SPH), Quetta, were approached for the study. All interviews were audio-taped, transcribed verbatim, and were then analyzed for thematic contents by the standard content analysis framework.ResultsAlthough the saturation was reached after the 13th interview, an additional two were interviewed for absolute validation. Content analysis revealed five major themes: (1) defining antibiotics and antibiotic resistance, (2) antibiotic use: awareness and concern, (3) antimicrobial resistance: awareness and concern, (4) responding to antibiotic use and resistance, and (5) barriers to quality use of antibiotics and prevention of antibiotic resistance. Even though the understanding of nurses regarding antibiotic use and resistance was promising, certain apprehensions were also observed. The respondents were aware of the critical situation and provided valuable insights that can offer significant input while promoting the quality use of antibiotics in a developing country.ConclusionWhile the perception towards antibiotics appeared positive, potential areas of concern and contributing factors regarding antibiotic resistance were also identified. Importantly, nurses too highlighted possible solutions to address the issue of irrational antibiotic use and the development of antibiotic resistance.

A survey of heavy metal contents of rural and urban roadside dusts: comparisons at low, medium and high traffic sites in Central Scotland.

Roadside dust can contain particulates enriched with potentially toxic elements (PTEs) as a result of the degradation of mechanical vehicular parts, tyre wear and combustion processes. To assess the potential accumulation of these metals in roadside areas, a snapshot study was carried out, investigating metal content at rural and urban locations in central Scotland. Samples of road dust were collected at six sites representing low, medium and high traffic intensity at rural and urban locations. The samples were separated based on particle size and analysed for heavy metal content using inductively coupled plasma optical emission spectroscopy (ICP-OES) after acid digestion. The metals analysed were aluminium (Al), cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), magnesium (Mg), manganese (Mn), lead (Pb) and zinc (Zn). The rural area measurements were carried out in West Lothian, approximately 13 to 17miles west of the city of Edinburgh (UK). The urban area measurements were carried out in the southern part of the Edinburgh city district (UK). Concentrations of Cu, Cr and Zn were found to correlate with traffic intensity, although only Cu and Zn concentrations exceed recommended EC directive 86/278/EEC guidelines for urban runoff materials. The metal concentrations of small particles (0.45-20μm) were exceedingly high in both Cu and Zn at areas of high traffic intensity, indicating potential areas of concern regarding health impacts for pedestrians and cyclists who are exposed to roadside dust on a regular basis.

Barriers to Health Care for Children with Orofacial Clefts: A Systematic Literature Review and Recommendations for Research Priorities

Background: There is a growing interest in health services research of orofacial clefts (OFC) in the United States. The objective of this study is to summarize the empirical knowledge to date about barriers to health care for children with OFC. Methods: We completed a systematic literature review to identify articles on barriers to health care for children with OFC in the United States. Pubmed, Embase, CINAHL, and Medline were searched from their dates of origin through June 2018 using a combination of key terms related to access and barriers to health care. Case reports and studies of populations outside of the United States were excluded. Results: 4079 publications were identified using our search strategy. After a title and abstract review, 18 were included in our review as they met inclusion criteria. These studies examined health care costs, health insurance coverage, access to team care, geographic barriers, adequacy of training of community-based providers in providing services to children with OFC, and socioeconomic and demographic factors. The key findings indicate much higher health care costs for children with OFC than unaffected children early in childhood, racial/ethnic disparities in certain access measures, and inadequate insurance coverage, distance to teams, and inadequate training of community-based providers in OFC-specific services as potential areas of concern. Except for studies on health care costs, the evidence is largely based on relatively small and primarily descriptive studies. Conclusions: The extant literature documents high health care costs for OFC treatments and suggests inadequate insurance coverage, long distance to cleft teams, and racial/ethnic disparities as critical factors related to access. We discuss multiple future research priorities. Among these, understanding the impacts of variation between states in mandates for private insurance benefits and generosity in Medicaid coverage on access to care as well as effects of differences in provider reimbursements are particularly understudied areas that can be meaningful for policymaking aimed at improving access and health outcomes of children with OFC. Examining access throughout childhood and later in life and employing robust designs and population-representative data are also important research and methodological extensions of the current literature.

Abstract IA17: The tobacco environment at the point of sale and the effects on vulnerable populations

Abstract This presentation will cover findings from a project in the tobacco retail environment of the Tobacco Center for Regulatory Sciences in Vulnerable Populations at USC. Qualitative and survey research was conducted among over 700 retailers and in retail outlets that sell tobacco products in vulnerable ethnic communities, including among American Indian tribal lands, in African American, Hispanic/Latino, Korean, and low-SES non-Hispanic White neighborhoods. Findings show violations to tobacco rulings as well as identify potential areas of concern and viable targeted and culturally tailored solutions to reducing exposure to environmental influences that foster and encourage the use of tobacco products in vulnerable communities.

Social Impact Bonds as a Funding Method for Health and Social Programs: Potential Areas of Concern.

Social Impact Bonds (SIBs) represent a new way to finance social service and health promotion programs whereby different types of investors provide an upfront investment of capital. If a given program meets predetermined criteria for a successful outcome, the government pays back investors with interest. Introduced in the United Kingdom in 2010, SIBs have since been implemented in the United States and across Europe, with some uptake in other jurisdictions. We identify and explore selected areas of concern related to SIBs, drawing from literature examining market-based reforms to health and social services and the evolution of the SIB funding mechanism. These areas of concern include increased costs to governments, restricted program scope, fragmented policymaking, undermining of public-sector service provision, mischaracterization of the root causes of social problems, and entrenchment of systemically produced vulnerabilities. We argue that it is essential to consider the long-term, aggregate, and contextualized effects of SIBs in order to evaluate their potential to contribute to public health. We conclude that such evaluations must explore the assumptions underlying the "common sense" arguments often used in support of SIBs.

Polypyrrole/carbon nanotube supercapacitors: Technological advances and challenges

Abstract The supercapacitors are advanced electrochemical energy storage devices having characteristics such as high storage capacity, rapid delivery of charge, and long cycle life. Polypyrrole (PPy) – an electronically conducting polymer, and carbon nanotubes (CNT) with high surface area and exceptional electrical and mechanical properties are among the most frequently studied advanced electrode materials for supercapacitors. The asymmetric supercapacitors composed of PPy/CNT composite electrodes offer complementary benefits to improve the specific capacitance, energy density, and stability. This article presents an overview of the recent technological advances in PPy/CNT composite supercapacitors and their limitations. Various strategies for synthesis and fabrication of PPy/CNT composites are discussed along with the factors that influence their ultimate electrochemical performance. The drawbacks and challenges of modern PPy/CNT composite supercapacitors are also reviewed, and potential areas of concern are identified for future research and development.

Auditing of discharge summaries Contet at Al Amal medical complex

Introduction and aimsPatient's records are the most important clinical assets and tools which are required in consultations. Patient records also support the accurate continuity of care when patients return to other health providers.ObjectiveUnderstand the extent of Discharge Summaries, which conform to the set best practise guidelines on the Mental Health Service.MethodA cross-section retrospective study on Discharge Summary contents was conducted at Al Amal Medical Complex. Chart review of randomly selected patient files (200 of a total 495), of Discharge Summaries for Psychiatric Patients in 2014 was performed. The data was statistically analysed using descriptive statistics taking into account proportions and frequencies. Pearson chi square and Fisher's test methodologies were used.ResultThis study found of the 200 randomly selected Discharge Summaries that documented data of mental health examination 94% (n = 188), data of discharge date 100% (n = 200) while data of social investigation and family work up 82% (n = 164). The above three categories were the only categories to conform to standard discharge guidelines. The other thirteen items studies were found not conforming to the defined standard guidelines.Conclusion and recommendationThere is an active challenge for clinicians to introduce good clinical practice in Mental Health. Standard guidelines must be followed by clinician's in order to reduce potential areas of concern and achieve a good clinical practise. Regular recurring audits are highly needed&amp; recommended to ensure the alignment with standard guidelines for the writing of Discharge Summaries.Disclosure of interestThe author has not supplied his/her declaration of competing interest.

Del Nido cardioplegia in adult cardiac surgery - scopes and concerns.

The convenience offered by a single-dose cardioplegia strategy is the avoidance of interruption of the flow of surgery and, more importantly, a significant reduction in the cross-clamp time. del Nido cardioplegia is an extracellular cardioplegic solution which serves these purposes and has been used successfully in pediatric cardiac surgery. The subsequent extrapolation of its use in adult cardiac surgery has returned encouraging results, as evidenced by recent literature. The use of del Nido cardioplegia in adults has been reported to shorten the cross-clamp time, cardiopulmonary bypass time and overall operating time. Intraoperative peak glucose value and insulin requirement have also been reported to be lower with del Nido cardioplegia, which can have prognostic significance. There have been reports of lesser incidence of atrial fibrillation and the number of defibrillations required with use of this technique. However, some unique concerns still remain. The lack of prospective randomized trials, the trend of elevation in CKMB (as reported by one study) and the need for a protocol-based approach to its use in adults are to be given due consideration while adopting its use in adults. This review attempts to have an overview on del Nido cardioplegia, its advantages, the recent studies comparing it with conventional cardioplegia techniques and the potential areas of concern with its use in adult cardiac surgery.

A case study for evaluating potential soil sensitivity in aridland systems.

Globally, ecosystems are subjected to prolonged droughts and extreme heat events, leading to forest die-offs and dominance shifts in vegetation. Some scientists and managers view soil as the main resource to be considered in monitoring ecosystem responses to aridification. As the medium through which precipitation is received, stored, and redistributed for plant use, soil is an important factor in the sensitivity of ecosystems to a drying climate. This study presents a novel approach to evaluating where on a landscape soils may be most sensitive to drying, making them less resilient to disturbance, and where potential future vegetation changes could lead to such disturbance. The drying and devegetation of arid lands can increase wind erosion, contributing to aerosol and dust emissions. This has implications for air quality, human health, and water resources. This approach combines soil data with vegetation simulations, projecting future vegetation change, to create maps of potential areas of concern for soil sensitivity and dust production in a drying climate. Consistent with recent observations, the projections show shifts from grasslands and woodlands to shrublands in much of the southwestern region. An increase in forested area occurs, but shifts in the dominant types and spatial distribution of the forests also are seen. A net increase in desert ecosystems in the region and some changes in alpine and tundra ecosystems are seen. Approximately 124,000 km(2) of soils flagged as "sensitive" are projected to have vegetation change between 2041 and 2050, and 82,927 km(2) of soils may become sensitive because of future vegetation changes. These maps give managers a way to visualize and identify where soils and vegetation should be investigated and monitored for degradation in a drying climate, so restoration and mitigation strategies can be focused in these areas.

Ethical implications of HIV self-testing

In April 2015, the first legally approved HIV self-testing kit went on sale in the UK—except Northern Ireland where they remain illegal. These tests allow individuals to test their HIV...
