OBJECTIVE:To obtain perspectives about existing compensation structures in gynecologic oncology, including common challenges and successful strategies within diverse systems. METHODS:Electronic mail was used to recruit OB/GYN department chairs and directors of cancer centers who were gynecologic oncologists and responsible for administering compensation structures at their institution. Using a semi-structured guide, three interviewers conducted 30-min qualitative interviews, which were recorded and transcribed. Two coders used the constant comparative method to summarize key themes. RESULTS:Response rate was 65 %, resulting in 17 interviewees. Participants were a third women and in their current position for a median of 7 years. The most prominent theme was the tension of balancing reimbursement for revenue-generating clinical activities with non-clinical work in research and education. Chair discretionary funds were useful to offset unfunded responsibilities. Broad clinical productivity measures were used: from more traditional work Relative Value Units (wRVUs) to measures that captured downstream impact, such as number of new patients or surgeries. Even in institutions with centralized funds flow systems, disparities were frequently noted for the monetary value assigned per wRVU. Academic scorecards were described as a method to ascribe value for academic work, often for bonus incentives. Another common stressor unique to gynecologic oncology was low reimbursement for chemotherapy-related services compared to surgery. Provision of regular productivity reports was common, but full transparency was controversial. CONCLUSIONS:Our inquiry demonstrates that our academic leaders are unable to use compensation to fully support areas they deem important.

Environmental exposure-associated diseases, particularly in the context of rising air pollution and inhalant use, are an active area of research. Our group is dedicated to the study of exposure-related inflammation and its downstream adverse health effects. While many studies have focused on the impact of environmental exposures on respiratory sequelae, there is growing evidence of the involvement of other systems including gastrointestinal. This systematic review provides updates on the associations between inhalation exposures and the risk of upper gastrointestinal disease. Primary search identified N = 764 PubMed and N = 1,036 Web of Science studies, of which N = 111 met eligibility criteria. Our systematic review and meta-analysis showed significant associations between inhalational exposures (cigarette smoking, waterpipe smoking, and particulate matter) and upper gastrointestinal diseases. The pooled estimate of esophagitis was 1.32 (95% confidence interval [CI], 1.06-1.65; I²:86%), gastroesophageal reflux disease was 1.71 (1.14-2.55; I²:94%), peptic ulcer disease was 1.21 (1.03-1.43; I²:93%), esophageal cancer was 1.83 (1.54-2.18; I²:73%), and gastric cancer was 1.71 (1.39-2.10; I²:73%). However, the pooled estimate for Barrett's esophagus was 0.93 (0.65-1.34; I²:76%), indicating no significant association. Sensitivity analyses confirmed these findings. Risk of bias assessment showed most studies were of good quality. Our findings emphasize the impact of inhalational exposures on gastrointestinal disease risk, highlighting the need for further research to better understand this interaction and targeted public health interventions.

BACKGROUND:Healthy Days at Home (HDaH) is a patient-centered outcome measure quantifying the number of days individuals spend at home without hospitalizations or emergency department (ED) visits, while maintaining functional independence. This study examines the association between HDaH and prognosis among US older adults with serious life-limiting illnesses (commonly heart failure, chronic obstructive pulmonary disease, advanced cancer, and end-stage kidney disease) and explores how this relationship differs by cancer status. METHODS:For this prospective cohort design study, we pooled Medicare Claims data of older adults (aged 66 or greater) with serious life-limiting illnesses who visited one of 30 EDs participating in the Primary Palliative Care for Emergency Medicine study between 2015 and 2019. The main exposure was prognosis, measured using the Gagne index, a short-term predictor of mortality. We controlled for age, sex, race/ethnicity, and used cancer diagnosis as a secondary predictor and stratification variable. The outcome, HDaH, was defined as 180 days minus the days a patient spent in healthcare institutions, including hospitals, skilled nursing facilities, and hospice care. We used generalized linear mixed-effects models with a log (180) offset to estimate the adjusted rate ratios (aRR) and 95% confidence intervals. RESULTS:The cohort included 122,579 seriously ill older adults,11% (n = 13,452) of whom had cancer. The median (IQR) HDaH was 115 (26-174) days. Each unit increase in Gagne index score was associated with a 6.0% decrease in the rate of HDaH (aRR: 0.94; 95% CI: 0.94 to 0.94), a pattern observed in both cancer and non-cancer groups. Cancer diagnosis was associated with 7.0% increase in HDaH (aRR: 1.07; 95% CI: 1.07 to 1.07). CONCLUSION/CONCLUSIONS:While poor prognosis is associated with fewer healthy days at home, cancer diagnosis is associated with more healthy days at home. Our findings highlight the need for tailored care models to reduce hospitalizations and increase HDaH for patients with serious life-limiting illnesses other than cancer.

INTRODUCTION/BACKGROUND:Social media is the most prominent source of online food and beverage advertisements (ads) seen by adolescents. Companies target adolescent social media users with ads that feature calorie-dense, nutrient-poor products, and exposure to ads drives poor diet and risk for future diet-related diseases. Black, Hispanic and lower socio-economic status youth are exposed to significantly more ads than White peers. Several state-level policies in the USA have passed restricting youth from accessing social media without parental approval, and some policies have banned advertising to youth. This protocol paper describes a current study that aims to understand the impact of such policies in two states, Louisiana and Texas, as they were among the first to be implemented with racially/ethnically diverse populations. METHODS AND ANALYSIS/METHODS:This study employs a repeated cross-sectional difference-in-difference design in which 700 youth ages 13-17 years are being recruited each year for 5 years (Louisiana n=175, Texas n=175, matched comparisons from other states n=350). Youth screen record their mobile devices for 60 minutes while they browse social media platforms (eg, TikTok, Instagram) or use the internet. They also complete a brief survey about a variety of topics (eg, health behaviours, mental health). Adolescents are compensated for screen recording ($75) and the survey ($25). Study team members are coding recordings for several characteristics, including media platforms used, appearances of food or beverages, and food or beverage type. We will estimate the impact of policies on food and beverage ads seen per hour using Ordinary Least Squares regression models and heterogeneity-robust standard errors clustered at the state level (by year and cumulatively). We will run additional models with interaction terms with income and race/ethnicity, separately, to test the role of the policies on health disparities. ETHICS AND DISSEMINATION/BACKGROUND:Study procedures have been approved by the Institutional Review Board of the NYU Grossman School of Medicine. We will distribute findings in peer-reviewed journals and at local and national conferences. To complement traditional dissemination pathways, we will create infographics to share with relevant community stakeholders. We will also share findings with policymakers in states that have passed or considered similar policies.

INTRODUCTION/BACKGROUND:Esophageal adenocarcinoma (EAC) develops through histopathological stages, including Barrett's esophagus (BE). We analyzed the associations between plasma levels of one-carbon metabolism factors and risks of long-segment BE or EAC. METHODS:Plasma levels were measured from an Irish population-based case-control study [Factors INfluencing the Barrett's Adenocarcinoma Relationship (FINBAR) study; 204 long-segment BE cases, 211 EAC cases, and 251 controls]. A "methyl replete score" was derived by assigning a score of 0 (< median) or 1 (> median) to the levels of three dietary methyl donors (methionine, choline, and betaine) and summing across the metabolites. Multinomial logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the associations between EAC or BE and sex-specific quartiles or score using the lowest level as the reference category and adjusted for potential confounders. RESULTS:Highest methionine, betaine, vitamin B6 (PLP), and choline levels were all associated with 62-82% reduced risks of EAC (ptrends <0.001). Conversely, S-adenosylmethionine (SAM), the SAM/S-adenosylhomocysteine (SAH) ratio, total homocysteine (tHcy), and cystathionine were associated with a greater than two-fold increased EAC risk. A higher methyl replete score was associated with reduced EAC risk (OR 0·33; 95%CI: 0·16-0·66). The highest versus lowest plasma methionine levels were borderline statistically significantly associated long-segment BE (OR 0·55; 95%CI: 0·28-1·07), but all other associations were null. CONCLUSIONS:Several biomarkers of one-carbon metabolism are associated with EAC risk, particularly markers of dietary methyl group donors. Future studies to replicate and prospectively evaluate these markers are warranted.

INTRODUCTION/BACKGROUND:Secondhand exposure to e-cigarettes represents a potential population health risk given e-cigarette's prevalence and their unknown health effects, particularly among vulnerable populations such as pregnant people. OBJECTIVES/OBJECTIVE:To explore metabolomic differences between pregnant people exposed vs. not exposed to secondhand e-cigarette aeresols, to identify possible biomarkers of exposure and metabolic pathways perturbed by e-cigarettes. METHODS:Exposed participants (n = 19) from the NYU Children's Health and Environment Study were matched to unexposed participants (n = 57) at a 1:3 ratio on age, hospital of recruitment, and race/ethnicity. Early-pregnancy urine samples were analyzed via an untargeted metabolomics platform using reverse-phase liquid chromatography mass-spectrometry. Feature-exposure associations were estimated using conditional logistic regression to adjust for matching factors. A sensitivity analysis was conducted adjusting for secondhand tobacco exposure. RESULTS:Among features enriched in the exposed group were flavonoids and flavor-related compounds including homoeriodictyol and naringenin-7-O-beta-D-glucuronide, 3-acetomidocoumarin, and guaiacol pentosylglucoside; synthetic drugs such as the endocannabinoid AM1172 and the stimulant alpha-PVP; and metabolites associated with lipid metabolism, including 2,4-undecadiene-8,10-diynoic acid isobutylamide, palmitamide, glycerol trihexanoate, and tetradecyl phosphonate. Among features negatively associated with exposure were xanthines. CONCLUSION/CONCLUSIONS:This study is the first untargeted metabolomics study investigating metabolomic markers of e-cigarette exposure, including secondhand exposure, in a pregnant cohort. Despite this study's small size and exploratory nature, the results of this work suggest that flavoring components could be biomarkers for e-cigarette exposure, and that co-exposure to e-cigarettes and other drugs may be prevalent.

Adverse environmental exposures worsened by our changing climate threaten respiratory health and exacerbate existing social inequities that further undermine environmental justice (EJ). EJ is the capacity of all people, regardless of sociodemographic characteristics, to minimize harmful exposures and live a healthy life. EJ is achieved through the development, implementation, and enforcement of environmental laws, regulations, and policies. In 2023, an American Thoracic Society workshop convened a group of 39 clinicians, researchers, community advocates, research program administrators, and health policy experts to characterize the respiratory health threats and EJ concerns arising from climate change. The workshop explored four main climate areas through a socioecological and EJ perspective: 1) respiratory health risks, 2) respiratory health impacts in low- and middle-income countries, 3) climate mitigation and adaptation strategies, and 4) priority research infrastructure needs. The workshop committee concluded that climate change can directly and indirectly impair respiratory health and that persistently excluded or marginalized communities (including those in low- and middle-income countries) are disproportionately impacted. These disproportionately impacted communities also lack hazard monitoring and resources to evaluate and advocate for mitigation of adverse environmental exposures. Future respiratory health research must inform mitigation strategies to reduce climate-related emissions from industry to net zero. Researchers, communities, and policymakers require training and support to meaningfully engage with systems-thinking research as well as policy solutions focused on mitigating and adapting to climate change. Finally, the workshop committee recommends a rapid transition away from fossil fuel dependence to a world that provides an equitable allocation of clean transportation options and renewable sources of energy production.

BACKGROUND/UNASSIGNED:Colorectal cancer screening can reduce colorectal cancer risk, yet many men are not up to date with screening guidelines. Although previous qualitative studies have suggested links among anti-gay prejudice, traditional masculine self-concept, racial identity, and colorectal cancer screening among men, scholars have yet to fully explore these associations using quantitative data. This study used a nationally representative sample of Black and White men in the United States to test these associations and examine the sociodemographic correlates. METHODS/UNASSIGNED:Using the National Opinion Research Center (NORC)/AmeriSpeak probability-based panel, we recruited a sample of Black and White men in the United States ages 45 to 74 years who had never been diagnosed with colorectal cancer (N = 909). Participants completed an online questionnaire measuring anti-gay prejudice, traditional masculine self-concept, sociodemographic variables, and screening-related outcomes (awareness of screening test options, screening intention, and adherence to screening recommendations). RESULTS/UNASSIGNED:Black participants reported higher levels of anti-gay prejudice and traditional masculine self-concept than White participants. Anti-gay prejudice was associated with lower awareness and lower screening intention. Black participants reported higher intention to follow screening recommendations but not higher odds of actual adherence than White participants. CONCLUSIONS/UNASSIGNED:Men with anti-gay prejudice are less likely to be aware of colorectal cancer screening test options and less likely to intend to engage in colorectal cancer screening. The results have implications for the design and development of future interventions aimed at increasing colorectal cancer screening rates. IMPACT/UNASSIGNED:Future studies could develop targeted interventions and observe subsequent changes or conduct longitudinal studies to further explore the role of anti-gay prejudice in colorectal cancer screening.

Altered fetal brain function is proposed as a mechanism underlying the relationship between prenatal maternal depression (PMD) and neurodevelopmental outcomes in offspring. This study investigated the association between PMD symptoms and fetal brain functional connectivity (FC) using graph theory. A total of 123 pregnant women participated in the study, completed the Center for Epidemiologic Studies Depression Scale (CES-D), and underwent fetal MRI scans. Results revealed a significant relationship between elevated PMD symptoms and reduced global efficiency in the right insular region of the fetal brain. However, because fetal age was not associated with local or global efficiency in the insular brain region, we cannot determine if the PMD-related reduction in insula global efficiency is indicative of an accelerated or delayed developmental pattern. This study is one of the few to examine fetal brain connectivity in relation to prenatal maternal depression, providing valuable insights into early neurodevelopmental risks and potential targets for early intervention.
