Abstract PO3-11-01: Single centre experience of the adoption of self-administered HER2-directed therapy in patients with breast cancer

Abstract Single centre experience of the adoption of self-administered HER2-directed therapy in patients with breast cancer Background: Programs to promote the self-administration of systemic anti-cancer therapy (SACT) offer greater convenience and shared decision making for patients with the opportunity to alleviate pressures on cancer services. Aims and Objective: The aims of this study were to quantify the uptake/acceptability of self-administration (SA) of subcutaneous trastuzumab (sc T), to evaluate safety, patients’ perception of the programme and the chair capacity released as a consequence. Methods: Patients receiving T for the treatment of HER2 +ve breast cancer were offered training in SA. The competency-based training programme, under the supervision of a chemotherapy-trained nurse, consisted of a minimum of 3 training sessions. Patients were also provided with printed and electronic material (via an App) on how to self-administer sc T, with 24/7 contact details in the event of an adverse event or device failure. Once trained and deemed competent, sc T was shipped to the patients’ home in a temperature-controlled environment, in a pre-filled syringe. All patients were assessed by telephone one day before and one day after SA using the Common Terminology Criteria for Adverse Events (CTCAE). Analysis of the total number of administrations of sc T, between February 2022 and June 2023 was conducted. A telephone survey using a validated questionnaire Self-Management Assessment scale (SMASc) was also undertaken. Results Of 46 breast cancer patients receiving single agent sc T, 32 agreed to participate in the program and were trained. 2 patients were undergoing training at data analysis. 6 patients declined and 6 were ineligible for the programme on the basis of inclusion criteria. The median age of the 32 patients that participated was 62, (range 27-77). The average distance from their home address to the cancer centre was 11.7 miles (range 3.5-27.9). 25 (78%) patients were Caucasian, 4 (13%) were Asian and 3 (9%) were of African/Caribbean origin. Patients had received an average of 10 sc injections in the hospital environment (median 5, range 1-103) before starting the training sessions. They required an average of 3 training sessions before sign-off (median 3, range 1-4). In the 32 patients studied, a total of 302 SA injections were delivered median 9 (range 1- 24) No Grade 3 or 4 CTCAE toxicities or infusion-related reactions were reported. During the 17-month period, a total of 302 hours of chair time was saved. 25 of the 32 patients responded to SMASc questionnaires utilising the six-point Likert scale. Patients reported average scores of 5.32 (median 6) and 5.56 (median 6) respectively, for questions relating to having information about their condition and sufficient training to self-administer. They felt that they had sufficient support to participate in the programme (average 5.56 median 6). 80% of the patients would recommend this programme and 88% felt they had benefited. Comments from patients themed around the value of the support provided, ease of administration and time saved. Discussion Programs such as these empower patients and carers to take a more active role in managing their condition with consequent reduced hospital attendance. Safety and acceptability for those patients who agreed to the program has been confirmed. Success of this program with sc T has enabled expansion to incorporate self-administration of Phesgo (sc trastuzumab and pertuzumab) with 31% (14/45) of the current P patient cohort enrolled onto the programme within 2 weeks of roll out and the first patients self-administering their treatment from August 2023. With the continued expansion of SACT treatments, we encourage stakeholders to consider self-administration of SACT as an option. Formulation of treatments conducive to patient self-administration is a key component to this.

Prenatal exposure to air pollutant mixtures and birthweight in the upstate KIDS cohort

BackgroundSingle-pollutant models have linked prenatal PM2.5 exposure to lower birthweight. However, analyzing air pollutant mixtures better captures pollutant interactions and total effects. Unfortunately, strong correlations between pollutants restrict traditional methods. ObjectivesWe explored the association between exposure to a mixture of air pollutants during different gestational age windows of pregnancy and birthweight. MethodsWe included 4,635 mother-infant dyads from a New York State birth cohort born 2008–2010. Air pollution data were sourced from the EPA’s Community Multiscale Air Quality model and matched to the census tract centroid of each maternal home address. Birthweight and gestational age were extracted from vital records. We applied linear regression to study the association between prenatal exposure to PM2.5, PM10, NOX, SO2, and CO and birthweight during six sensitive windows. We then utilized Bayesian kernel machine regression to examine the non-linear effects and interactions within this five-pollutant mixture. Final models adjusted for maternal socio-demographics, infant characteristics, and seasonality. ResultsSingle-pollutant linear regression models indicated that most pollutants were associated with a decrement in birthweight, specifically during the two-week window before birth. An interquartile range increase in PM2.5 exposure (IQR: 3.3 µg/m3) from the median during this window correlated with a 34 g decrement in birthweight (95 % CI: −54, −14), followed by SO2 (IQR: 2.0 ppb; β: −31), PM10 (IQR: 4.6 µg/m3; β: −29), CO (IQR: 60.8 ppb; β: −27), and NOX (IQR: 7.9 ppb; β: −26). Multi-pollutant BKMR models revealed that PM2.5, NOX, and CO exposure were negatively and non-linearly linked with birthweight. As the five-pollutant mixture increased, birthweight decreased until the median level of exposure. DiscussionPrenatal exposure to air pollutants, notably PM2.5, during the final two weeks of pregnancy may negatively impact birthweight. The non-linear relationships between air pollution and birthweight highlight the importance of studying pollutant mixtures and their interactions.

Systematically assessing the quality of dental electronic health record data for an investigation into oral health care disparities.

This work describes the process by which the quality of electronic health care data for a public health study was determined. The objectives were to adapt, develop, and implement data quality assessments (DQAs) based on the National Institutes of Health Pragmatic Trials Collaboratory (NIHPTC) data quality framework within the three domains of completeness, accuracy, and consistency, for an investigation into oral health care disparities of a preventive care program. Electronic health record data for eligible children in a dental accountable care organization of 30 offices, in Oregon, were extracted iteratively from January 1, 2014, through March 31, 2022. Baseline eligibility criteria included: children ages 0-18 with a baseline examination, Oregon home address, and either Medicaid or commercial dental benefits at least once between 2014 and 2108. Using the NIHPTC framework as a guide, DQAs were conducted throughout data element identification, extraction, staging, profiling, review, and documentation. The data set included 91,487 subjects, 11 data tables comprising 75 data variables (columns), with a total of 6,861,525 data elements. Data completeness was 97.2%, the accuracy of EHR data elements in extracts was 100%, and consistency between offices was strong; 29 of 30 offices within 2 standard deviations of the mean (s = 94%). The NIHPTC framework proved to be a useful approach, to identify, document, and characterize the dataset. The concepts of completeness, accuracy, and consistency were adapted by the multidisciplinary research team and the overall quality of the data are demonstrated to be of high quality.

Barriers to dental utilization among Medicaid-enrolled young children from primary care practices in Northeast Ohio.

To evaluate the individual and community factors that contribute to dental utilization among young children on Medicaid utilizing the Anderson Model and the Socio-Ecological Framework. This observational cross-sectional study was conducted using baseline data (socio-demographics, clinical dental need) from a cluster-randomized hybrid effectiveness-implementation trial among 1021 child-parent dyads recruited from primary care practices across northeast Ohio. The baseline data were then linked to dental Medicaid claims data (categorized as any dental visit, volume, and type in the past 12 months) and ICD-10 codes from the child's EHR data (individual-level) together with Dental Health Provider Shortage Area (HPSA) status and Area Deprivation Index (ADI) which were obtained at the neighbourhood-level using home address of each dyad (community-level). Multivariable analyses using generalized estimating equations (GEE) accounted for clustering by practice, and models included individual-level alone, and individual + community-level factors to evaluate their effects on dental utilization. Medicaid claims data indicated that among the 1021 children (mean age: 4.3 ± 1.1 years; 54.4% males; 43.8% Black, Non-Hispanic), a majority of children were seeing the dentist at least once a year by the age of 4 (56.1%). The mean ADI of their neighbourhoods was 109.22 (20.2) and 27.5% lived in a HPSA area. The GEE analyses revealed that individual factors such as older children, parents being married, and continuous Medicaid enrollment were associated with significantly higher dental utilization. Among community factors, being in a HPSA had an OR = 1.53 (CI: 1.03, 2.27) associated with higher dental utilization. Being in a HPSA was associated with higher dental utilization possibly due to dentists or safety net dental clinics in these areas accepting Medicaid-eligible children.

Social cohesion and associations with sedentary time, physical activity and dietary quality in The Maastricht Study

IntroWe aim to investigate the relationship between social cohesion and sedentary behavior (SB), total physical activity (PA), moderate-to-vigorous PA (MVPA), and dietary quality. Additionally, we assess whether these associations are independent of neighborhood walkability and the food environment. MethodsA total of 7641 participants from The Maastricht Study in the Netherlands between the ages of 40 and 75 years were analyzed. Neighborhood social cohesion was obtained by participant questionnaire completed at baseline and measured by the Dutch Livability meter. Home addresses were linked to geographic information system (GIS) data from the Geoscience and Health Cohort Consortium (GECCO) to create neighborhood exposures of walkability and food environment. A thigh worn accelerometer collected data to measure sedentary time, total daily PA, and MVPA. Dietary quality was measured with a food frequency questionnaire. Multivariate linear regression analyses were adjusted for age, sex, socioeconomic position, neighborhood walkability, and food environment. ResultsThose living in the highest quartile area of perceived social cohesion had statistically significant lower levels of SB (Q4 B: -13.04; 95% CI = −20.23, −5.85), higher total PA (Q4 B: 4.39; 95% CI = 1.69, 7.10), and higher MVPA (Q4 B: 2.57; 95% CI = 0.83, 4.31) and better diet quality (Q4 B: 1.12; 95% CI = 0.24, 2.01) compared to the lowest quartile independent of walkability and food environment. Similar results were found using the Livability meter. ConclusionWe discovered neighborhood social cohesion as an important obesogenic determinant that should be considered in policymaking to encourage higher levels of PA and higher diet quality.

Residential Greenness, Lifestyle, and Vitamin D: A Longitudinal Cohort of South Asian Origin and Caucasian Ethnicity Women Living in the South of the UK.

The global population is at risk of vitamin D deficiency due to low exposure to sunlight and low intake of the vitamin through diet. The aim of this study was to investigate in women the association between vitamin D status and parathyroid hormone (PTH), ultraviolet radiation, lifestyle, ethnicity, social conditions, and residential greenness. A 1-year longitudinal study assessed vitamin D status in 309 women living at latitude 51°14' N. Blood samples were taken four times throughout the year for analysis of 25(OH)D and serum PTH concentration. After each seasonal visit, the individuals completed 4-day diet diaries and used two dosimeter badges for 1 week to estimate weekly UVR exposure. A questionnaire was applied to provide information about lifestyle and their ethnicity. Residential greenness was measured by Normalized Difference Vegetation Index (NDVI), within a 1000 m radius around each participant's home address. Women living in greener spaces were more likely to have improved vitamin D status (RR: 1.51; 95%CI: 1.13-2.02), as well as those who were more exposed to UVR (RR: 2.05; 95%CI: 1.44-2.92). Our results provide an insight into the connection between residential greenness, lifestyle, and vitamin D status comparing two ethnicities in a country with a temperate climate and with a high degree of urbanization.

Educational nutritional intervention to prevent loss of health-related quality of life among older adults after a surgical treatment: design of a randomised controlled trial.

Disease-related malnutrition after a hospital stay has major consequences for older adults, the healthcare system and society. This study aims to develop and test the effectiveness of an educational video to prevent loss of health-related quality of life among live-at-home older adults after surgical treatment in a hospital. This randomised controlled trial will occur at a regional hospital in Norway. Participants will be live-at-home adults aged 65years and older. They will be recruited from three different surgical departments after a surgical procedure. Individuals with a body mass index below 24 and a home address in one of nine selected municipalities will be eligible for inclusion. Participants will be randomly assigned to either the intervention group or the control group. Those assigned to the intervention group will obtain access to a 6-min educational video 5days after being discharged from the hospital. The control group will not obtain access to the video. The primary outcome will be health-related quality of life using the Norwegian Rand 36-Item Short Form Health Survey. Furthermore, we will measure body composition, number of readmissions and nutritional knowledge at inclusion and 3-month follow-up. This randomised controlled trial is expected to provide insight into whether an educational video can improve the nutritional status of older adults following a surgical procedure and discharge from the hospital. The findings will be useful for assessing how videos offering nutritional advice to older adults who have undergone a surgical procedure can improve their health-related quality of life, reduce loss of function, prevent readmission to hospital and reduce healthcare costs.

Distance to Burn Center Does Not Impact Long-term Anxiety and Depression Risk Following Burn Injury.

Burn injury predisposes patients to significant psychological morbidity, including anxiety, depression, and posttraumatic stress. Adding to the burden of injury, patients often require transfer to specialized burn centers located far from home. We hypothesized that greater distances between a patient's home address and the treating burn center would increase the rate of postinjury anxiety and depression. From January 2021 to June 2023, patients who were admitted to our American Burn Association verified center and seen for posthospitalization follow-up were identified. Demographics, burn characteristics, and follow-up anxiety (Generalized Anxiety Disorder-7) and depression (Patient Health Questionnaire-2) screening scores were reviewed. Comparisons between patients with positive and negative screens were performed using univariate analysis followed by logistic regression. Linear regression was used to evaluate the relationship between distance to the burn center and incremental screening scores. Of the 272 patients identified, 35.6% and 27.9% screened positive for anxiety and depression, respectively. The distance to burn center was not greater among patients with positive screens. Likewise, no statistically significant linear relationship was found between distance to the burn center and incremental screening scores. Morphine milligram equivalents on the last day of hospitalization (P = .04) and a prior psychiatric history (P < .001) all predicted postinjury anxiety. Total body surface area burned (P = .02) and a prior psychiatric history (P = .02) predicted postinjury depression. The distance between a patient's home and the treating burn center does not alter anxiety and depression rates following burn injury, further supporting the transfer of patients to specialized centers.

Familiar Locations and Similar Activities: Examining the Contributions of Reliable and Relevant Knowledge in Offenders’ Crime Location Choices

This paper examines the recently theorized roles of the reliability and relevance of offenders’ knowledge of locations in their crime location choices. Using discrete choice models, we analyzed offenders’ pre-offense activity locations from police data (home addresses, family members’ home addresses, work, school, prior offenses, victimizations, non-crime incidents, and other police contacts) and 17,054 residential burglaries, 10,353 non-residential burglaries, 1,977 commercial robberies, 4,315 personal robberies, and 4,421 extra-familial sex offenses, in New Zealand. Offenders were most likely to offend where their prior activity locations indicated they had highly reliable and highly relevant knowledge—where they were both highly familiar with the area and had conducted similar activities—and less likely where offenders had less familiarity or less similar activities. The results support a recent extension of crime pattern theory and highlight the importance of including both reliability and relevance factors when modeling or predicting offenders’ crime location choices.

Carbon savings potential of virtual care in obstructive sleep apnea and otitis media with effusion.

To determine the carbon savings potential of incorporating virtual care into surgical care pathways for pediatric patients with obstructive sleep apnea or otitis media with effusion. Pediatric patients with obstructive sleep apnea or otitis media with effusion were not enrolled, instead, a modeling cohort study design was used. This study utilized the British Columbia healthcare system and geography to model emissions. Care pathways were developed for pediatric patients with obstructive sleep apnea or otitis media with effusion requiring care at a tertiary pediatric center. Home addresses were located at the geographical center of the two most populated municipalities within each of the 10 most populated regional districts in 2020. Virtual visits replaced up to three clinically equivalent in-person visits. Emissions (kgCO2e) for transport and virtual visits were estimated. Population-weighted means and descriptive statistics were calculated. Utilizing 1, 2, or 3 virtual visits in the obstructive sleep apnea care pathway yielded potential emissions savings of 19.9%, 39.9%, and 59.8% respectively. Integrating 1, 2, or 3 virtual visits into the otitis media with effusion care pathway produced potential emissions savings of 16.6%, 33.2%, and 49.7%, respectively. Integrating 3 virtual visits can save up to 2156.8 kgCO2e per patient. Appropriately conducting up to 50% of clinical encounters virtually for children with obstructive sleep apnea or otitis media with effusion reduced theoretical carbon emissions. For a single child, emission savings could reach over 2150 kgCO2e. Level 5.

Examining the relationship of flavored tobacco product policy restrictions and flavored tobacco product use, among adolescents and young adults in the U.S.

ObjectiveThis work examines the relationship between local flavor policy exposure and any tobacco product use and flavored tobacco product use among U.S. youth and young adults, as well as the equity potential of these policies by race/ethnicity. MethodsParticipants were aged 15–36 (n = 10,893) surveyed from September–December 2019 using national, address- and probability-based sampling. Local flavor policies enacted before survey completion were linked to participant home address. Weighted cross-sectional multivariable logistic regression examined individual coverage by flavor policy vs. no flavor policy, with current any tobacco or flavored tobacco use, controlling for individual and county-level demographics, psychosocial variables, and other tobacco control policies. Interactions between race/ethnicity and any tobacco use and flavored tobacco use were assessed. ResultsThose covered by a flavor policy vs. no policy had lower odds of any tobacco use (aOR = 0.74, 95% CI = 0.55–1.00) and current flavored tobacco use (aOR = 0.67, 95% CI = 0.48–0.93). Compared with Non-Hispanic (NH)-White individuals, NH-Black individuals (aOR = 1.08, CI = 1.04–1.12) had higher odds of any tobacco use, and non-Hispanic Asian individuals had lower odds of any tobacco use (aOR = 0.67, CI = 0.53–0.85). Hispanic individuals exposed to policy had lower odds of flavored tobacco use compared to NH-White peers. ConclusionsExposure to flavor restriction policies is associated with lower odds of any tobacco and flavored use among youth and young adults. Flavor restrictions may be beneficial in reducing tobacco use in youth from diverse racial/ethnic backgrounds. However, passing policies covering NH-Black individuals is needed to mitigate disparities in tobacco use by flavor policy coverage over time.

Long-term exposure to major constituents of fine particulate matter and neurodegenerative diseases: A population-based survey in the Pearl River Delta Region, China

BackgroundExposure to PM2.5 has been linked to neurodegenerative diseases, with limited understanding of constituent-specific contributions. ObjectivesTo explore the associations between long-term exposure to PM2.5 constituents and neurodegenerative diseases. MethodsWe recruited 148,274 individuals aged ≥ 60 from four cities in the Pearl River Delta region, China (2020 to 2021). We calculated twenty-year average air pollutant concentrations (PM2.5 mass, black carbon (BC), organic matter (OM), ammonium (NH4+), nitrate (NO3-) and sulfate (SO42-)) at the individuals' home addresses. Neurodegenerative diseases were determined by self-reported doctor-diagnosed Alzheimer’s disease (AD) and Parkinson’s disease (PD). Generalized linear mixed models were employed to explore associations between pollutants and neurodegenerative disease prevalence. ResultsPM2.5 and all five constituents were significantly associated with a higher prevalence of AD and PD. The observed associations generally exhibited a non-linear pattern. For example, compared with the lowest quartile, higher quartiles of BC were associated with greater odds for AD prevalence (i.e., the adjusted odds ratios were 1.81; 95% CI, 1.45–2.27; 1.78; 95% CI, 1.37–2.32; and 1.99; 95% CI, 1.54–2.57 for the second, third, and fourth quartiles, respectively). ConclusionsLong-term exposure to PM2.5 and its constituents, particularly combustion-related BC, OM, and SO42-, was significantly associated with higher prevalence of AD and PD in Chinese individuals. Environmental implicationPM2.5 is a routinely regulated mixture of multiple hazardous constituents that can lead to diverse adverse health outcomes. However, current evidence on the specific contributions of PM2.5 constituents to health effects is scarce. This study firstly investigated the association between PM2.5 constituents and neurodegenerative diseases in the moderately to highly polluted Pearl River Delta region in China, and identified hazardous constituents within PM2.5 that have significant impacts. This study provides important implications for the development of targeted PM2.5 prevention and control policies to reduce specific hazardous PM2.5 constituents.

Interpersonal Violence and Social Determinants of Health.

Social determinants of health (SDOH) influence patient outcomes and risk assessment. This study focuses on interpersonal violence, trauma outcomes, and SDOH. We hypothesized patients with lower SDOH experience worse trauma outcomes and present from higher-risk communities. Demographics, SDOH, and outcomes for patients admitted to surgical trauma suffering interpersonal violence were collected and analyzed. Home addresses were plotted, identifying areas of need compared with Area Deprivation Index (ADI). Only 18.8% of patients had documented SDOH, yielding small sample size. Analysis revealed no statistically significant associations (P < .05) between SDOH and trauma outcomes, including ICU length of stay and stress concern (P = .0804). Heat mapping revealed several hot spots across our catchment area, correlating with higher-ranked ADIs and increased deprivation. This study demonstrated SDOH can bring value in determining patient risk, emphasizing resource dedication to documenting these factors. Home addresses in conjunction with ADIs can ascertain areas for resource allocation within communities.

Is the Child Opportunity Index a Factor in Surgical Outcomes for Adolescent Idiopathic Scoliosis?

Low socioeconomic status (SES) has been previously associated with delays in orthopaedic care. However, it is unclear how SES impacts patients with adolescent idiopathic scoliosis (AIS), particularly regarding preoperative major coronal curve angle or surgical outcomes. Utilizing the Child Opportunity Index (COI)-an address-driven measure of pediatric education, health/environment, and SES-we investigated whether COI is associated with differences in preoperative scoliosis magnitude, age at surgery, and AIS surgical outcomes. Consecutive patients with AIS surgically treated at a single center from 2011 to 2017 were reviewed. COI was calculated by inserting a patient's home address into the nationally available COI database to derive a COI value. COI is scored from 0.0 to 100.0 (0.0 is lowest, 100.0 is highest). Specifically, COI is categorized as very low (<20.0), low (20 to 39.9), moderate (40 to 59.9), high (60 to 79.9), and very high (≥80). Those without addresses were excluded. Patients without proper radiographs to assess curve correction were also excluded. A COI threshold of 60.0 was used to separate patients into a low (<60.0) or high COI () group based on published COI guidelines. Outcomes, including preoperative curve magnitude, age at surgery, percentage curve correction, operative time (OT), intraoperative estimated blood loss per level fused, length of stay, and complications, were compared across groups. Pearson correlation analysis was used to assess correlations between COI and preoperative curve magnitude, as well as age. Four hundred four patients were included in the study, and 263 had 2-year follow-up data. Patients were an average age of 14.9 years old (range: 11.2 to 19.8), had a median COI of 76 (range: 4 to 100), and had a mean preoperative major curve angle of 59 degrees (range: 36 to 93). COI was significantly higher for white patients compared with non-white (80.0 vs 40.0, P < 0.001), and higher for non-Hispanic individuals (79.0 vs 15.0, P < 0.001). Patients with Low COI were associated with a lower OT per level fused (P = 0.003) and decreased postoperative complication risk (P = 0.02). COI was not associated with preoperative major coronal curve angle, age at surgery, or any other surgical outcomes. COI was significantly lower for non-white patients and those of Hispanic ethnicity. Patients from low COI backgrounds achieved similar surgical results as those from high COI addresses and had a decreased OT per level fused and complication incidence, though the clinical significance of these differences is unknown. Future prospective studies are needed to determine whether these findings are reproducible across other states and health systems. Level III-prognostic study.

A comprehensive environmental exposure indicator and respiratory health in asthmatic children: a case study

AbstractThe primary goal of asthma management is to achieve and maintain asthma control, which can be influenced by environmental factors. This longitudinal study aimed to construct a comprehensive environmental indicator to predict asthma control in children with asthma in Palermo, Italy. The study included 179 asthmatic children aged 5–16 years. The Normalized Difference Vegetation Index (NDVI) was used to measure green cover, and the Coordination of Information on the Environment (CORINE) framework was used to assess land use based on each home address. A land use regression (LUR) model centered on the home address estimated NO2 exposure for each child using GIS. An environmental indicator, including environmental and personal exposure, was formulated using an additive value model approach. A logistic regression mixed model assessed the association between the environmental indicator and uncontrolled asthma. A probability map of uncontrolled asthma was constructed. In conclusion, a comprehensive environmental indicator proved effective in identifying areas at higher and lower risk of uncontrolled asthma.

Exposure to di-2-ethylhexyl phthalate and breast neoplasm incidence: A cohort study

BackgroundPhthalates are ubiquitous environmental endocrine disruptors. As the predominant phthalate, di-2-ethylhexyl phthalate (DEHP) has been considered possibly carcinogenic to humans but large-scale longitudinal evidence is needed to further clarify its carcinogenicity. ObjectivesTo examine the association between DEHP exposure and incidence of breast malignant neoplasm, carcinoma in situ and benign neoplasm. MethodsA total of 273,295 women from UK Biobank cohort were followed up for a median of 13.5 years. Disease information was collected from National Health Service Cancer Registry and National Death Index. Baseline and yearly-average level of DEHP exposure were estimated for each individual by linking chemical monitoring record of European Environment Agency with home address of the participants by Kriging interpolation model. Cox proportional hazard model was employed to estimate the association between DEHP exposure and breast neoplasms. ResultsThe median (IQR) of baseline and yearly-average DEHP concentration were 8000.25 (interquartile range: 6657.85–11,948.83) and 8000.25 (interquartile range: 1819.93–11,359.55) μg/L. The highest quartile of baseline DEHP was associated with 1.11 fold risk of carcinoma in situ (95 % CI, 1.00, 1.23, p < 0.001) and 1.27 fold risk of benign neoplasm (95 % CI, 1.05, 1.54, p < 0.001). As for yearly-average exposure, each quartile of DEHP was positively associated with higher risk of malignant neoplasm (HR, 1.05; 95 % CI, 1.03, 1.07, p < 0.001), carcinoma in situ (HR, 1.08; 95 % CI, 1.04, 1.11, p < 0.001) and benign neoplasm (HR, 1.13; 95 % CI, 1.07, 1.20, p < 0.001). Stratification analysis showed no significant modification effects on the DEHP-neoplasm relationship by menopausal status or ethnicity but a suggestive higher risk in younger women and those who underwent oral contraceptive pill therapy. In sensitivity analysis, the associations remained when excluding the cases diagnosed within 2 years post baseline. ConclusionsReal-world level of DEHP exposure was associated with higher risk of breast neoplasms. Because of the health risks associated with DEHP, its release to the environment should be managed.

Cohort profile: China undergraduate cohort for environmental health study

The China Undergraduate Cohort (CUC) is an ambispective cohort study with its major purpose to better understand the effects of lifetime environmental exposures on health outcomes. We recruited 5322 college students with an average age of 18.3 ± 0.7 years in China from August 23, 2019 to October 28, 2019. Follow-up surveys were conducted annually. The dataset comprises individual demographic data (e.g. age, sex, height, weight, birth date, race, home address, annual family income, contact information), health-related behavior data (smoking status, smoking cessation, passive smoking exposure, drinking habit, physical activity, dietary status), lifestyle data (physical exercise, dietary habit, length of time spent outdoors), disease history (respiratory disease history, cardiovascular disease history, urinary system disease history, etc.), mental health status data (sleep quality, self-reported stress, anxiety and depression symptoms), lung function and blood samples data. Preliminary results from our cohort have found the association between air pollution, summer heat and mercury exposure and lung function among young adults in China.

Environmental radon, fracking wells, and lymphoma in dogs.

Multicentric lymphoma (ML) in dogs resembles non-Hodgkin lymphoma (NHL) in humans. Human NHL is associated with multiple environmental exposures, including to radon and volatile organic compounds (VOCs). The objective of this study was to determine whether ML in dogs was associated with environmental radon or proximity to horizontal oil and drilling (fracking), a source of VOC pollution. We identified dogs from the Golden Retriever Lifetime Study that developed ML (n = 52) along with matched controls (n = 104). Dog home addresses were categorized by Environmental Protection Agency radon zone and average residential radon by county, as well as by distance from fracking and associated wastewater wells. We found no significant differences in county level radon measurements. Individual household radon measurements were not available. There was no difference in residential proximity to active fracking wells between dogs with ML and unaffected dogs. While dogs with ML lived closer to wastewater wells (123 vs 206 km; P = .01), there was no difference in the percentage of cases vs controls that lived in close proximity (20 km) to a fracking well (11.5% for cases, 6.7% for controls; OR 1.81, 95% CI 0.55 to 5.22; P = .36), or a wastewater well (6.7% for cases, 4.4% for controls; P > .99). These data suggest that more proximate sources of chemical exposures need to be assessed in dogs with ML, including measurements of individual household radon and household VOC concentrations.

Neighborhood-level social determinants of health and cardioprotective behaviors among church members in New Orleans, Louisiana

BackgroundFavorable neighborhood-level social determinants of health (SDoH) are associated with lower cardiovascular disease risk. Less is known about their influence on cardioprotective behaviors. We evaluated the associations between neighborhood-level SDoH and cardioprotective behaviors among church members in Louisiana. MethodsParticipants were surveyed between November 2021 to February 2022, and were asked about health behaviors, aspects of their neighborhood, and home address (to link to census tract and corresponding social deprivation index [SDI] data). Logistic regression models were used to assess the relation of neighborhood factors with the likelihood of engaging in cardioprotective behaviors: 1) a composite of healthy lifestyle behaviors [fruit and vegetable consumption, physical activity, and a tobacco/nicotine-free lifestyle], 2) medication adherence, and 3) receipt of routine medical care within the past year. ResultsParticipants (n = 302, mean age: 63 years, 77% female, 99% Black) were recruited from 12 churches in New Orleans. After adjusting for demographic and clinical factors, perceived neighborhood walkability or conduciveness to exercise (odds ratio [OR]=1.25; 95% CI: 1.03, 1.53), availability of fruits and vegetables (OR=1.23; 95% CI: 1.07, 1.42), and social cohesion (OR=1.55; 95% CI: 1.22, 1.97) were positively associated with the composite of healthy lifestyle behaviors. After multivariable adjustment, SDI was in the direction of association with all three cardioprotective behavior outcomes, but associations were not statistically significant. ConclusionsIn this predominantly Black, church-based population, neighborhood-level SDoH including the availability of fruits and vegetables, walkability or conduciveness to exercise, and social cohesion were associated with cardioprotective behaviors. Findings reiterate the need to address adverse neighborhood-level SDoH in the design and implementation of health interventions.
