Saving lives in our homes: Qualitative evaluation of a tenant overdose response program in supportive, single-room occupancy (SRO) housing.

BACKGROUND: People using opioids alone in private settings are at elevated risk of dying in the event of an overdose. In San Francisco, single room occupancy (SRO) tenants are 19 times more likely to die of overdose than non-SRO residents. The "SRO Project" pilot aimed to reduce fatal overdoses in SROs by recruiting and training tenants to distribute naloxone and provide overdose education in their buildings. We explore the implementation and program impacts of the SRO Project pilot in two permanent supportive housing SROs. METHODS: We conducted eight months of ethnographic fieldwork (May 2021 - Feb 2022), including 35 days observing SRO Project pilot activities, and semi-structured interviews with 11 housing staff and 8 tenant overdose prevention specialists ('specialists'). Data were analyzed using a grounded theory approach to characterize program impacts, implementation strengths, and implementation challenges from the perspective of specialists and housing staff. FINDINGS: We found that the SRO project increased awareness, access to, and understanding of naloxone; facilitated other mutual-aid practices; supported privacy and autonomy of tenants regarding their drug use; and improved rapport, communication and trust between tenants and housing staff. Strengths of the implementation process included involvement of tenants with diverse social locations and skill sets and, at one site, a team-based approach that fostered program innovation, tenant solidarity and a sense of collective ownership over the project. Program implementation was challenged by frequent turnover and capacity constraints of housing staff, particularly during overnight shifts when overdose risks were greatest. Additional challenges arose due to the psychosocial burden of overdose response work, gendered violence, issues with compensation methods, and scope creep in specialists' roles. CONCLUSION: This evaluation contributes further evidence regarding the effectiveness of tenant-led naloxone distribution and overdose education in permanent supportive and SRO housing environments. Findings indicate program implementation and sustainability can be improved by expanding tenant specialist training, compensating specialists in cash, and building stronger psychosocial support for tenants responding to overdoses in their homes.

Vulnerability to typhoons: A comparison of consequence and driving factors between Typhoon Hato (2017) and Typhoon Mangkhut (2018).

Typhoon disasters have caused casualties, property loss, and other negative impacts to social and economic development. Vulnerability is an important component of typhoon risk. However, little is known about the contributions of vulnerability factors and their interaction effects on typhoon-induced losses at a fine scale. Focusing on the vulnerability measures of Typhoon Hato in 2017 and Typhoon Mangkhut in 2018, this study aims to quantify the contribution and interactive effects of physical and socioeconomic factors on vulnerability based on the GeoDetector method and determine the factors that account for most of the change in vulnerability. The results show that from Typhoon Hato in 2017 to Typhoon Mangkhut in 2018, the vulnerability of the economy and houses decrease on average. Rain intensity and wind intensity are the dominant factors of disaster loss for Typhoon Hato and Typhoon Mangkhut, respectively. Vegetation cover and landform explain vulnerability better than average slope in most instances. For different loss types, the dominant socioeconomic vulnerability factor is different. For both typhoons, emergency transfer has a higher determining power (q) ranking for the population vulnerability, while the percentage of the GDP made up of primary industry have higher q ranking for economic vulnerability. The dominant interaction effects between two vulnerability factors differ depending on the typhoon and loss type but show a nonlinear enhancement effect in most cases. Moreover, changes in the maximum 4-hour accumulated rainfall account for most of the change in vulnerability between Hato and Mangkhut. Overall, the results can be conducive to understanding the complexity of vulnerability to typhoons and provide a reference for possible indicators for vulnerability assessment models, and determining the reasons for changes in vulnerability can be constructive to the formulation of specific policies for disaster prevention and mitigation.

Malaria prevention interventions beyond long-lasting insecticidal nets and indoor residual spraying in low- and middle-income countries: a scoping review.

BACKGROUND: Significant progress in malaria prevention during the past two decades has prompted increasing global dialogue on malaria elimination. Recent reviews on malaria strategies have focused mainly on long-lasting insecticidal nets (LLINs) and indoor residual spraying (IRS), with little emphasis on other prevention methods. This article is a scoping review of literature on malaria prevention methods beyond LLINs and IRS in low- and middle-income countries (LMICs). METHODS: This scoping review found articles published between from 1994 to 2020. Studies were obtained from a search of the PubMed, the Cochrane Library and Social Science abstracts. Grey literature and manual search of secondary references was also done. The search strategy included all study designs but limited only to English. Three independent reviewers performed the selection and characterization of articles, and the data collected were synthesized qualitatively. RESULTS: A total of 10,112 studies were identified among which 31 met the inclusion criteria. The results were grouped by the 3 emerging themes of: housing design; mosquito repellents; and integrated vector control. Housing design strategies included closing eves, screening of houses including windows, doors and ceilings, while mosquito repellents were mainly spatial repellents, use of repellent plants, and use of plant-based oils. Integrated vector control included larvae source management. Evidence consistently shows that improving housing design reduced mosquito entry and malaria prevalence. Spatial repellents also showed promising results in field experiments, while evidence on repellent plants is limited and still emerging. Recent literature shows that IVM has been largely ignored in recent years in many LMICs. Some malaria prevention methods such as spatial repellents and IVM are shown to have the potential to target both indoor and outdoor transmission of malaria, which are both important aspects to consider to achieve malaria elimination in LMICs. CONCLUSION: The scoping review shows that other malaria prevention strategies beyond LLINs and IRS have increasingly become important in LMICs. These methods have a significant role in contributing to malaria elimination in endemic countries if they are adequately promoted alongside other conventional approaches.

Linear Growth Faltering Is Associated with Subsequent Adverse Child Cognitive Developmental Outcomes in the Democratic Republic of the Congo (REDUCE Program).

Globally, 140 million children under 5 years of age are estimated to be stunted. Previous studies have found an association between stunting and poor cognitive outcomes. However, there is limited evidence of this association in sub-Saharan African settings, such as the Democratic Republic of the Congo (DRC). This prospective cohort study of 286 children under 5 years was conducted in rural DRC to investigate the association between diarrhea prevalence, child growth, and child cognitive developmental outcomes. Developmental outcomes were assessed by communication, fine motor, gross motor, personal social, problem-solving, and combined developmental scores measured by the Extended Ages and Stages Questionnaire (EASQ) at a 6-month follow-up visit. Height and weight were measured at baseline and a 6-month follow-up. Diarrhea prevalence was assessed through surveillance visits. Diarrhea prevalence was not associated with follow-up combined EASQ Z-scores at the 6-month follow-up (coefficient: -0.06 [95% CI: -0.29, 0.17]). Each additional standard deviation (SD) increase in height-for-age Z-scores from baseline to the 6-month follow-up increased combined EASQ Z-scores by 0.22 (95%: 0.14, -0.31) SDs. Each additional SD increase in weight-for-age Z-scores from baseline to the 6-month follow-up increased combined EASQ Z-scores by 0.21 (95%: 0.10, -0.32) SDs. Linear growth faltering and reduced weight gain were associated with reduced cognitive developmental outcomes among children residing in rural DRC. Interventions are urgently needed for this susceptible pediatric population to improve child growth and cognitive developmental outcomes.

Social Stressors, Arboviral Infection, and Immune Dysregulation in the Coastal Lowland Region of Ecuador: A Mixed Methods Approach in Ecological Perspective.

Aedes aegypti, the mosquito that transmits arboviral diseases such as dengue (DENV), chikungunya (CHIKV), and Zika viruses (ZIKV), is present in tropical and subtropical regions of the world. Individuals at risk of mosquito-borne disease (MBD) in the urban tropics face daily challenges linked to their socio-environment conditions, such as poor infrastructure, poverty, crowding, and limited access to adequate healthcare. These daily demands induce chronic stress events and dysregulated immune responses. We sought to investigate the role of socio-ecologic risk factors in distress symptoms and their impact on biological responses to MBD in Machala, Ecuador. Between 2017 and 2019, individuals (≥ 18 years) with suspected arbovirus illness (DENV, ZIKV, and CHIKV) from sentinel clinics were enrolled (index cases, N = 28). Cluster investigations of the index case households and people from four houses within a 200-m radius of index home (associate cases, N = 144) were conducted (total N = 172). Hair samples were collected to measure hair cortisol concentration (HCC) as a stress biomarker. Blood samples were collected to measure serum cytokines concentrations of IL-10, IL-8, TNF-α, and TGF-ß. Univariate analyses were used to determine the association of socio-health metrics related to perceived stress scores (PSS), HCC, and immune responses. We found that housing conditions influence PSS and HCC levels in individuals at risk of MBD. Inflammatory cytokine distribution was associated with the restorative phase of immune responses in individuals with low-moderate HCC. These data suggest that cortisol may dampen pro-inflammatory responses and influence activation of the restorative phase of immune responses to arboviral infections.

Persistently high SARS-CoV-2 positivity rate and incidence for Hispanic/Latinos during state reopening in an urban setting: a retrospective cohort study.

Hispanic/Latino populations are disproportionately impacted by coronavirus disease 2019 (COVID-19) in the United States. The impact of state reopening on COVID-19 in this population after stay-at-home orders is unknown. We evaluated the incidence, prevalence and trends during reopening of severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) at a major federally qualified health centre in Providence, Rhode Island. A total of 14 505 patients were tested for SARS-CoV-2 from 19 March to 18 August 2020, of which, data on 13 318 (91.8%) patients were available; 70.0% were Hispanic/Latino, and 2905 were positive for SARS-CoV-2 infection. The urban Hispanic/Latino population was almost five times more likely to test positive for SARS-CoV-2 (risk ratio 4.97, 95% CI 2.59-9.53, P < 0.001) compared to non-Hispanic White. The positivity rates among the urban Hispanic/Latino population remained >10% during all phases of reopening. The trends of the incidence rates showed similar associations to those we observed for positivity rates. Public health interventions to address SARS-CoV-2 in Hispanic/Latino communities are urgently needed, even in latter phases of state reopening.

Study of Effectiveness of Prior Knowledge for Smart Home Kit Installation.

Smart-Home in a Box (SHiB) is a ubiquitous system that intends to improve older adults' life quality. SHiB requires self-installation before use. Our previous study found that it is not easy for seniors to install SHiB correctly. SHiB CBLE is a computer-based learning environment that is designed to help individuals install a SHiB kit. This article presents an experiment examining how smart home sensor installation was affected by knowledge gained from two methods, SHiB CBLE, and a written document. Results show that participants who were trained by the CBLE took significantly (p<0.05) less time in the installation session than those in the control group. The accuracy rate of SHiB kit installation is 78% for the group trained by the CBLE and 77% for the control group. Participants trained by the CBLE showed significantly (p<0.01) higher confidence in the actual installation than those in the control group. These results suggest that having a training before the actual installation will help installers avoid unnecessary work, shorten the installation time, and increase installers' confidence.

Self-Reported Exposure to Secondhand Smoke and Support for Complete Smoking Bans in Multiunit Housing Among Smokers in the United States, Canada, and the United Kingdom.

INTRODUCTION: Involuntary exposure to secondhand smoke most frequently occurs at home, which is problematic for residents of multiunit housing (MUH). The primary objective of this study was to estimate the extent of secondhand smoke incursions into the homes of MUH smokers who banned smoking in their homes but lived in buildings where smoking is allowed. METHODS: We used data from Wave 9 of the International Tobacco Control Four Country Survey. We estimated 1) the prevalence of complete smoking bans among smokers living in single-family homes vs MUH in the United States (n = 3,208), Canada (n = 1,592), and the United Kingdom (n = 1,403) from 2013 to 2015; 2) the extent of secondhand smoke incursions into the homes of MUH smokers who banned smoking in their units but lived in buildings that allow smoking; and 3) MUH smokers' preferences for complete smoking bans in MUH. Weighted multivariable logistic regression estimated the country-specific adjusted prevalence of all outcomes. RESULTS: Overall, 53.0% of smokers living in single-family homes completely banned smoking in their homes, compared with 44.8% of smokers in MUH. Across all 3 countries, only 27.8% of MUH smokers reported that smoking was completely prohibited in their building. A similar percentage of MUH smokers who banned smoking in their home but lived in buildings allowing smoking reported a secondhand smoke incursion into their home in the United States (29.9%; 95% CI, 20.4%-41.5%), Canada (38.4%; 95% CI, 26.7%-51.6%), and the United Kingdom (24.7%; 95% CI, 15.7%-36.7%). Across all 3 countries, 36.1% (95% CI, 33.4%-38.9%) of smokers in MUH reported they preferred a complete smoking ban in all building areas. CONCLUSION: A need remains to educate MUH operators and residents about the benefits of comprehensive smoke-free policies.

Bad Air Can Also Kill: Residential Indoor Air Quality and Pollutant Exposure Risk during the COVID-19 Crisis.

During the first outbreak of the SARS-CoV-2 pandemic the population, focusing primarily on the risk of infection, was generally inattentive to the quality of indoor air. Spain, and the city of Madrid in particular, were among the world's coronavirus hotspots. The country's entire population was subject to a 24/7 lockdown for 45 days. This paper describes a comparative longitudinal survey of air quality in four types of housing in the city of Madrid before and during lockdown. The paper analysed indoor temperatures and variations in CO2, 2.5 µm particulate matter (PM2.5) and total volatile organic compound (TVOC) concentrations before and during lockdown. The mean daily outdoor PM2.5 concentration declined from 11.04 µg/m3 before to 7.10 µg/m3 during lockdown. Before lockdown the NO2 concentration values scored as 'very good' 46% of the time, compared to 90.9% during that period. Although the city's outdoor air quality improved, during lockdown the population's exposure to indoor pollutants was generally more acute and prolonged. Due primarily to concern over domestic energy savings, the lack of suitable ventilation and more intensive use of cleaning products and disinfectants during the covid-19 crisis, indoor pollutant levels were typically higher than compatible with healthy environments. Mean daily PM2.5 concentration rose by approximately 12% and mean TVOC concentration by 37% to 559%. The paper also puts forward a series of recommendations to improve indoor domestic environments in future pandemics and spells out urgent action to be taken around indoor air quality (IAQ) in the event of total or partial quarantining to protect residents from respiratory ailments and concomitantly enhanced susceptibility to SARS-CoV-2, as identified by international medical research.

Measuring ventilation in different typologies of rural Gambian houses: a pilot experimental study.

BACKGROUND: African houses are frequently too hot and uncomfortable to use a bed net at night. Indoor thermal comfort is often evaluated by measuring temperature and humidity, ignoring ventilation. This study explored ways to measure ventilation in single-roomed rural Gambian houses during the malaria transmission season and evaluated building designs that could increase airflow at night and help keep the occupants comfortable. METHODS: Two identical mud-walled houses were constructed with a metal roof, three doors and closed eaves. Experiment 1 compared five methods for measuring ventilation in a building: (1) using a blower door, (2) increasing carbon dioxide (CO2) levels indoors using an artificial source of CO2 and then measuring the rate of gas decay, (3) using a similar approach with a natural source of CO2, (4) measuring the rise of CO2 when people enter a building and (5) using hot-wire anemometers. Experiment 2 used CO2 data loggers to compare ventilation in a reference metal-roofed house with closed eaves and badly-fitting doors with a similar house with (1) thatched roof and open eaves, (2) eaves tubes, (3) screened doors and (4) screened doors and windows. RESULTS: In experiment 1, CO2 data loggers placed indoors in two identical houses showed similar changes in airflow (p > 0.05) for all three methods recording either decreasing or increasing CO2. Blower doors were unable to measure airflow in houses with open eaves or screened windows and the anemometers broke down under field conditions. In experiment 2, open eaves in thatched houses, screened doors alone, and screened doors and windows increased indoor ventilation compared to the reference metal-roofed house with closed eaves and badly fitting doors (p < 0.05). Eaves tubes did not increase ventilation in comparison to the reference house. CONCLUSION: CO2 data loggers proved to be a simple and efficient method for measuring ventilation in rural houses at night. Ventilation of metal-roofed houses can be improved by adding two screened doors and windows on opposite walls. Improved ventilation will result in increased thermal comfort making it more likely that people will sleep under a bed net.

Mental Health Outcomes Among Homeless, Runaway, and Stably Housed Youth.

BACKGROUND AND OBJECTIVES: Runaway youth and homeless youth are at risk for adverse mental health outcomes. These 2 populations are frequently pooled together in both research and interventions yet may have unique health needs. We sought to assess differences in mental health outcomes among these populations. METHODS: We conducted a secondary data analysis of ninth- and 11th-graders in the 2016 minnesota Student Survey (n = 68 785). We categorized youth into 4 subgroups based on housing status in the previous year: (1) unaccompanied homeless youth (0.5%), (2) runaway youth (4%), (3) youth who had both run away and been homeless (0.6%), and (4) stably housed youth (95%). We performed multivariable logistic regression to compare 4 mental health outcomes (self-injury, suicidal ideation, suicide attempts, and depressive symptoms) across groups, controlling for demographics and abuse history. RESULTS: Unstably housed youth had poorer mental health outcomes when compared with their stably housed peers (P < .05). For example, 11% of homeless youth, 20% of runaways, and 33% of youth who had experienced both had attempted suicide in the previous year compared with 2% of stably housed youth (adjusted odds ratios 2.4, 4.9, and 7.1, respectively). Other outcomes showed a similar pattern. CONCLUSIONS: Our findings suggest that runaway and homeless youth represent unique populations with high levels of mental health needs who would benefit from targeted clinical and community interventions. Pediatric clinicians represent one potential point of screening and intervention.

Influence of house characteristics on mosquito distribution and malaria transmission in the city of Yaoundé, Cameroon.

BACKGROUND: Improving house structure is known to limit contact between humans and mosquitoes and reduce malaria transmission risk. In the present study, the influence of house characteristics on mosquito distribution and malaria transmission risk was assessed in the city of Yaoundé. METHODS: The study was conducted from March 2017 to June 2018 in 32 districts of the city of Yaoundé. Mosquito collections were performed indoor in 10 to 15 houses per district using CDC light traps. A total of 467 houses, selected randomly were used. A pretested questionnaire was submitted to participants of the study to collect information on the household: the number of people per house, education level, type of walls, presence of ceilings and eaves, number of windows, usage of long-lasting insecticidal nets (LLINs), number of bedroom and number of window. Mosquitoes collected were identified morphologically. Anophelines were tested by ELISA to detect infection by Plasmodium parasites. General Estimating Equations adjusting for repeated measures in the same house fitting negative binomial analysis were used to assess the influence of house characteristics on mosquito distribution. RESULTS: A total of 168,039 mosquitoes were collected; Culex spp emerged as the predominant species (96.48%), followed by Anopheles gambiae sensu lato (s.l.) (2.49%). Out of the 1033 An. gambiae s.l. identified by PCR, 90.03% were Anopheles coluzzii and the remaining were An. gambiae sensu stricto (s.s.) (9.97%). The high number of people per household, the presence of screens on window and the possession of LLINs were all associated with fewer mosquitoes collected indoors, whilst opened eaves, the high number of windows, the presence of holes in walls and living close to breeding sites were associated with high densities of mosquitoes indoor. Out of 3557 Anophelines tested using ELISA CSP, 80 were found infected by Plasmodium falciparum parasites. The proportion of mosquitoes infected did not vary significantly according to house characteristics. CONCLUSION: The study indicated that several house characteristics such as, the presence of holes on walls, opened eaves, unscreened window and living close to breeding sites, favored mosquito presence in houses. Promoting frequent use of LLINs and house improvement measures, such as the use of screen on windows, closing eaves, cleaning the nearby environment, should be integrated in strategies to improve malaria control in the city of Yaoundé.

Geographical distribution of Anopheles stephensi in eastern Ethiopia.

BACKGROUND: The recent detection of the South Asian malaria vector Anopheles stephensi in Ethiopia and other regions in the Horn of Africa has raised concerns about its potential impact on malaria transmission. We report here the findings of a survey for this species in eastern Ethiopia using both morphological and molecular methods for species identification. METHODS: Adult and larval/pupal collections were conducted at ten sites in eastern Ethiopia and Anopheles specimens were identified using standard morphological keys and genetic analysis. RESULTS: In total, 2231 morphologically identified An. stephensi were collected. A molecular approach incorporating both PCR endpoint assay and sequencing of portions of the internal transcribed spacer 2 (ITS2) and cytochrome c oxidase subunit 1 (cox1) loci confirmed the identity of the An. stephensi in most cases (119/124 of the morphologically identified An. stephensi confirmed molecularly). Additionally, we observed Aedes aegypti larvae and pupae at many of the An. stephensi larval habitats. CONCLUSIONS: Our findings show that An. stephensi is widely distributed in eastern Ethiopia and highlight the need for further surveillance in the southern, western and northern parts of the country and throughout the Horn of Africa.

Preferred resting surfaces of dominant malaria vectors inside different house types in rural south-eastern Tanzania.

BACKGROUND: Malaria control in Africa relies extensively on indoor residual spraying (IRS) and insecticide-treated nets (ITNs). IRS typically targets mosquitoes resting on walls, and in few cases, roofs and ceilings, using contact insecticides. Unfortunately, little attention is paid to where malaria vectors actually rest indoors, and how such knowledge could be used to improve IRS. This study investigated preferred resting surfaces of two major malaria vectors, Anopheles funestus and Anopheles arabiensis, inside four common house types in rural south-eastern Tanzania. METHODS: The assessment was done inside 80 houses including: 20 with thatched roofs and mud walls, 20 with thatched roofs and un-plastered brick walls, 20 with metal roofs and un-plastered brick walls, and 20 with metal roofs and plastered brick walls, across four villages. In each house, resting mosquitoes were sampled in mornings (6 a.m.-8 a.m.), evenings (6 p.m.-8 p.m.) and at night (11 p.m.-12.00 a.m.) using Prokopack aspirators from multiple surfaces (walls, undersides of roofs, floors, furniture, utensils, clothing, curtains and bed nets). RESULTS: Overall, only 26% of An. funestus and 18% of An. arabiensis were found on walls. In grass-thatched houses, 33-55% of An. funestus and 43-50% of An. arabiensis rested under roofs, while in metal-roofed houses, only 16-20% of An. funestus and 8-30% of An. arabiensis rested under roofs. Considering all data together, approximately 40% of mosquitoes rested on surfaces not typically targeted by IRS, i.e. floors, furniture, utensils, clothing and bed nets. These proportions were particularly high in metal-roofed houses (47-53% of An. funestus; 60-66% of An. arabiensis). CONCLUSION: While IRS typically uses contact insecticides to target adult mosquitoes on walls, and occasionally roofs and ceilings, significant proportions of vectors rest on surfaces not usually sprayed. This gap exceeds one-third of malaria mosquitoes in grass-thatched houses, and can reach two-thirds in metal-roofed houses. Where field operations exclude roofs during IRS, the gaps can be much greater. In conclusion, there is need for locally-obtained data on mosquito resting behaviours and how these influence the overall impact and costs of IRS. This study also emphasizes the need for alternative approaches, e.g. house screening, which broadly tackle mosquitoes beyond areas reachable by IRS and ITNs.

The Impact of Socio-Economic and Home Environmental Factors on Oral Health-Related Quality of Life Among Children Aged 11-14.

Background and Objectives: Oral diseases are known to negatively impact physical, functional, and emotional well-being, and thus adversely affect quality of life. The aims of the study were (1) to assess the oral health-related quality of life (OHRQoL) and (2) to explore socio-demographic, -economic, and -environmental factors that are associated with OHRQoL among a sample of children aged 11-14 in Saudi Arabia. Materials and Methods: A cross-sectional design was used. The Child Perceptions Questionnaire (CPQ)-a self-administered, validated, and standardized questionnaire was used to collect data on OHRQoL in four domains: oral symptoms, functional limitations, and emotional and social well-being. In addition, data were collected on home environment, socioeconomic/demographic characteristics, and oral hygiene practices of participants and their parents or adult guardians. Univariate descriptive statistics, Spearman's correlation, and Kruskal-Wallis H and Mann-Whitney tests were used. Data were analyzed using SPSS 23 Software. Significance was set at α = 0.05. Results: In total, 534 children participated in the study (91% response rate), of which 60% were females. Twenty percent of children described their oral health as "poor" and one in every four children reported that their oral health had at least some effect on their overall well-being. Children who were male, attending public schools, and living with both parents were more likely to report poor OHRQoL. Conclusions: A considerable proportion of children aged 11-14 could discern that their oral health had some effect on their overall well-being. The results identified potential predictors of OHRQoL. Disparities in OHRQoL exist among certain sub-populations. Active efforts and local interventions are necessary to improve OHRQoL.

Lead Poisoning in Children.

Asymptomatic lead poisoning has become more common in children. Blood lead levels of less than 5 µg per dL are associated with impairments in neurocognitive and behavioral development that are irreversible. Risk factors for lead poisoning include age younger than five years, low socioeconomic status, living in housing built before 1978, and use of imported food, medicines, and pottery. The U.S. Preventive Services Task Force released a recommendation in 2019 citing insufficient evidence to assess the balance of benefits and harms of universal screening for elevated blood lead levels in asymptomatic children and pregnant women. Local risk factors can be substantial, and the Centers for Disease Control and Prevention (CDC) recommends that states and cities formulate their own targeted screening guidelines. In the absence of local guidance, the CDC recommends screening all Medicaid-eligible children at 12 months and again at 24 months, or at least once between 36 and 72 months if not previously screened. The CDC also recommends universal screening in areas where more than 27% of the housing was built before 1950, or where at least 12% of children 12 to 36 months of age have blood lead levels greater than 10 µg per dL. Life-threatening lead levels are treated with chelation therapy, and lower levels should prompt case management and environmental investigations to identify and remove the source of exposure. Primary prevention strategies are essential to eliminate the harmful effects of lead on child development.

Prefabricated Temporary Housing and Eczema or Respiratory Symptoms in Schoolchildren after the Great East Japan Earthquake: The ToMMo Child Health Study.

OBJECTIVE: We aimed to investigate the association between types of housing and allergic symptoms at 3-4 years following the Great East Japan Earthquake. METHODS: Our study was based on the ToMMo Child Health Study conducted in 2014 and 2015, a cross-sectional survey of public school children in Miyagi Prefecture, Japan. Of the 46 648 invited schoolchildren in the 2nd to 8th grades, 9884 were included. Presence of eczema, wheezing, and mental health symptoms was defined with questionnaires. To calculate odds ratios (ORs) and 95% CIs for the associations between types of housing and eczema or respiratory symptoms, we fitted generalized linear mixed models, included a random effect for municipality of residence, and adjusted for sex, school grade, survey year, and mental health symptoms. RESULTS: Prefabricated temporary housing was significantly associated with eczema symptoms (OR, 1.46; 95% CI, 1.06-2.02). Even after adjusting for the presence of mental health symptoms, our analysis produced similar results (OR, 1.42; 95% CI, 1.03-1.96). Conversely, it was not significantly associated with respiratory symptoms (OR, 0.97; 95% CI, 0.61-1.54). CONCLUSIONS: Children living in prefabricated temporary housing had a higher prevalence of eczema symptoms; however, prevalence of respiratory symptoms was not significantly higher.

Effect of vertical location on survival outcomes for out-of-hospital cardiac arrest in Singapore.

BACKGROUND: A large proportion of out-of-hospital cardiac arrest (OHCA) cases occur in high-rise residential buildings. This study aims to investigate the effect of vertical location on survival outcomes and response times. METHODS: This is a retrospective study based on data obtained from the Singapore cohort of the Pan-Asian Resuscitation Outcomes Study (PAROS) from January 2011 to December 2014. Study subjects were OHCA cases, unwitnessed and transported by EMS personnel, with known vertical location (floor) data. Traumatic arrests with no resuscitation attempted and missing vertical locations were excluded. The primary outcome was survival to hospital discharge or 30 days post-cardiac arrest. RESULTS: A total of 5678 OHCA cases were included in the study. The effect of floors on survival was manifested as a U-shaped response. Survival rates of 4.5% for the 4 pooled basement floors and 6.2% for the ground floor (floor 1) were contrasted by a substantial drop to 2.7% at floor 2 and continuing decline to 0.7% at floor 6. In a multivariable model using stepwise logistic regression, both linear (p = 0.0285) and quadratic (p = 0.0018) floor effects remained significant after adjustment for other significant risk factors, age, bystander witnessed arrest, first arrest rhythm, ROSC on scene/enroute, and EMS response times. Harrell's C-statistic for a predictive model incorporating these variables was 0.933. CONCLUSIONS: Vertical location is associated with OHCA survival probability with a U-shaped response, and this significance remained after adjustment for other significant OHCA variables. This relationship is likely multifactorial and more research is needed to elucidate the various factors.

Determinantes sociales de la salud de distintos niveles por género: educación y hogar en España / Social determinants of health at distinct levels by gender: education and household in Spain

Objetivo: Explorar desde una perspectiva de género la asociación con la salud subjetiva de la interacción del nivel educativo y la tipología de hogar en el marco de los determinantes sociales de la salud (DSS) en los niveles micro y mezzo. Método: Los datos utilizados proceden de la muestra española de la Encuesta Europea de Condiciones de Vida para el año 2014. La asociación entre la interacción de ambos DSS con la salud autopercibida se ha analizado mediante modelos de regresión logística separados para mujeres y hombres. El modelo con la interacción se ha contrastado con el modelo aditivo para evaluar las posibles ventajas. Resultados: El modelo para la interacción muestra una reducción o incluso la desaparición de los efectos negativos sobre la salud de aquellas tipologías de hogar asociadas con una peor salud cuanto mayor es el nivel educativo, mostrando especificidades propias para cada sexo. Conclusiones: Los perfiles de mala salud de mujeres y hombres se dibujan de manera más precisa al combinar ambos DSS. Entre las mujeres se confirma el papel destacado que ambos DSS tienen para entender sus desigualdades en salud. Entre los hombres, sobre todo aquellos con menor nivel educativo, la interacción destapa una mayor importancia del hogar como DSS. De este modo se podrán diseñar políticas públicas más efectivas para disminuir las desigualdades tanto de género como de salud

Objective: To explore from a gender perspective the association with subjective health of the interaction between education and household arrangements within the framework of social determinants of health placed at the micro and mezzo levels. Methods: The data comes from the Spanish sample of the European Union Statistics on Income and Living Conditions for 2014. Independent logistic regression models for men and women were run to analyze the association with subjective health of the interaction between education and household arrangements. An additive model was run to assess possible advantages over the interaction approach. Results: The interaction models show a lower or even no significant effect on health of household arrangements usually negatively associated with health among individuals with high education, displaying specific patterns according to sex. Conclusions: Health profiles of women and men are more precisely drawn if both social determinants of health are combined. Among the women, the important role was confirmed of both social determinants of health in understanding their health inequalities. Among the men, mainly those with low educational achievement, the interaction revealed that the household was a more meaningful social determinant of health. This could enable the definition of more efficient public policies to reduce health and gender inequalities

The Influence of Residence Type on Personal Outcomes.

Over the last 5 decades, the state institution census has decreased 85% in the United States. Despite these radical shifts away from institutionalization, people with intellectual and developmental disabilities (IDD) continue to struggle to be meaningfully included in the community. For these reasons, the aim of this study was to explore if and how residence type affects attainment of quality of life outcomes of people with IDD in the United States. To do so, we analyzed Personal Outcome Measures® interviews from approximately 1,350 people with IDD. Findings suggest much of what has historically been considered deinstitutionalization of people with IDD is transinstitutionalization, particularly with provider-owned or -operated settings. A systemic overhaul is needed to create an effective community infrastructure.
