Background: Gastric cancer is the third most common cause of cancer death worldwide. In the US, gastric cancer incidence for Chinese Americans is nearly twice that for non-Hispanic whites. Cancer is the leading cause of death among Chinese New Yorkers who experience higher mortality for gastric cancer than other New Yorkers overall. The bacterium Helicobacter pylori (H. pylori) is the strongest risk factor for gastric cancer, and eradication of H. pylori through triple antibiotic therapy is the most effective prevention strategy for gastric cancer. Despite the elevated burden, there are no culturally and linguistically tailored evidence-based intervention strategies to address H. pylori medication adherence and gastric cancer prevention for Chinese Americans in NYC, a largely foreign-born (72%), limited English proficient (61%), and low-income (21% living in poverty) population.
Objective(s): The study objective was to develop and pilot a community health worker (CHW)-delivered linguistically and culturally adapted gastric cancer prevention intervention to improve H. pylori treatment adherence and address modifiable cancer prevention risk factors, including improved nutrition for low-income, LEP, Chinese American immigrants.
Method(s): We used a mixed methods and community-engaged research approach to develop and pilot the intervention curriculum and materials. Methods included: 1) a comprehensive scoping review of the peer-reviewed and grey literature on gastric cancer prevention programs and strategies targeting Chinese Americans; 2) 15 key informant interviews with gatekeepers and stakeholders serving the New York Chinese immigrant community to assess the knowledge and perception of H. pylori infection and gastric cancer among Chinese New Yorkers; and 3) pilot implementation of the collaboratively developed intervention with H. pylori-infected LEP Chinese immigrant participants (n=7).
Result(s): Study process findings and pilot results will be presented. Preliminary results indicate high patient- and community-level need and acceptability for the intervention. Baseline and 1-month post-treatment outcomes and survey data, qualitative data analysis of the CHW session notes, and key informant interviews will be presented.
Conclusion(s): Findings suggest that a CHW-delivered culturally adapted gastric cancer prevention intervention can result in meaningful health information and treatment adherence for at-risk, low-income Chinese immigrant communities. Study findings are being applied to inform a randomized controlled trial being implemented in safety net hospital settings

BACKGROUND:Researchers must often rely on creatinine measurements to assess kidney function because direct glomerular filtration rates (GFR) and cystatin-c are rarely measured in routine clinical settings. However, HIV treatments often include dolutegravir, raltegravir, rilpivirine or cobicistat, which inhibit the proximal tubular secretion of creatinine without impairing kidney function, thus leading to measurement bias when using creatinine-based estimated GFR (eGFR). We developed eGFR correction factors to account for this potential bias. METHODS:(multivariate Cox proportional hazards models) were estimated with and without eGFR correction. RESULTS:compared to efavirenz. CONCLUSIONS:With increasing use of agents that inhibit tubular creatinine secretion, artificially low eGFR values could lead to erroneous conclusions in studies of HIV treatment and kidney outcomes measured with creatinine-based eGFR equations. Sensitivity analyses assessing the potential magnitude of bias arising from creatinine secretion inhibition should be performed.

Importance/UNASSIGNED:Black and Hispanic populations have higher rates of coronavirus disease 2019 (COVID-19) hospitalization and mortality than White populations but lower in-hospital case-fatality rates. The extent to which neighborhood characteristics and comorbidity explain these disparities is unclear. Outcomes in Asian American populations have not been explored. Objective/UNASSIGNED:To compare COVID-19 outcomes based on race and ethnicity and assess the association of any disparities with comorbidity and neighborhood characteristics. Design, Setting, and Participants/UNASSIGNED:This retrospective cohort study was conducted within the New York University Langone Health system, which includes over 260 outpatient practices and 4 acute care hospitals. All patients within the system's integrated health record who were tested for severe acute respiratory syndrome coronavirus 2 between March 1, 2020, and April 8, 2020, were identified and followed up through May 13, 2020. Data were analyzed in June 2020. Among 11 547 patients tested, outcomes were compared by race and ethnicity and examined against differences by age, sex, body mass index, comorbidity, insurance type, and neighborhood socioeconomic status. Exposures/UNASSIGNED:Race and ethnicity categorized using self-reported electronic health record data (ie, non-Hispanic White, non-Hispanic Black, Hispanic, Asian, and multiracial/other patients). Main Outcomes and Measures/UNASSIGNED:The likelihood of receiving a positive test, hospitalization, and critical illness (defined as a composite of care in the intensive care unit, use of mechanical ventilation, discharge to hospice, or death). Results/UNASSIGNED:Among 9722 patients (mean [SD] age, 50.7 [17.5] years; 58.8% women), 4843 (49.8%) were positive for COVID-19; 2623 (54.2%) of those were admitted for hospitalization (1047 [39.9%] White, 375 [14.3%] Black, 715 [27.3%] Hispanic, 180 [6.9%] Asian, 207 [7.9%] multiracial/other). In fully adjusted models, Black patients (odds ratio [OR], 1.3; 95% CI, 1.2-1.6) and Hispanic patients (OR, 1.5; 95% CI, 1.3-1.7) were more likely than White patients to test positive. Among those who tested positive, odds of hospitalization were similar among White, Hispanic, and Black patients, but higher among Asian (OR, 1.6, 95% CI, 1.1-2.3) and multiracial patients (OR, 1.4; 95% CI, 1.0-1.9) compared with White patients. Among those hospitalized, Black patients were less likely than White patients to have severe illness (OR, 0.6; 95% CI, 0.4-0.8) and to die or be discharged to hospice (hazard ratio, 0.7; 95% CI, 0.6-0.9). Conclusions and Relevance/UNASSIGNED:In this cohort study of patients in a large health system in New York City, Black and Hispanic patients were more likely, and Asian patients less likely, than White patients to test positive; once hospitalized, Black patients were less likely than White patients to have critical illness or die after adjustment for comorbidity and neighborhood characteristics. This supports the assertion that existing structural determinants pervasive in Black and Hispanic communities may explain the disproportionately higher out-of-hospital deaths due to COVID-19 infections in these populations.

OBJECTIVE:Scalable, accessible forms of behavioral therapy for migraine prevention are needed. We assessed the feasibility and acceptability of progressive muscle relaxation (PMR) delivered by a smartphone application (app) in the Primary Care setting. METHODS:This pilot study was a non-blinded, randomized, parallel-arm controlled trial of adults with migraine and 4+ headache days/month. Eligible participants spoke English and owned a smartphone. All participants were given the RELAXaHEAD app which includes an electronic headache diary. Participants were randomized to receive 1 of the 2 versions of the app-one with PMR and the other without PMR. The primary outcomes were measures of feasibility (adherence to the intervention and diary entries during the 90-day interval) and acceptability (satisfaction levels). We conducted exploratory analyses to determine whether there was a change in Migraine Disability Assessment Scale (MIDAS) scores or a change in headache days. RESULTS:Of 139 participants (77 PMR, 62 control), 116 (83%) were female, mean age was 41.7 ± 12.8 years. Most patients 108/139 (78%) had moderate-severe disability. Using a 1-5 Likert scale, participants found the app easy to use (mean 4.2 ± 0.7) and stated that they would be happy to engage in the PMR intervention again (mean 4.3 ± 0.6). For the first 6 weeks, participants practiced PMR 2-4 days/week. Mean per session duration was 11.1 ± 8.3 minutes. Relative to the diary-only group, the PMR group showed a greater non-significant decline in mean MIDAS scores (-8.7 vs -22.7, P = .100) corresponding to a small-moderate mean effect size (Cohen's d = 0.38). CONCLUSION/CONCLUSIONS:Smartphone-delivered PMR may be an acceptable, accessible form of therapy for migraine. Mean effects show a small-moderate mean effect size in disability scores.

In recent years, intragastric balloons (IGBs) have emerged as an efficacious, nonsurgical modality to treat obesity. We present a case in which an IGB caused a gastric ulcer, only unearthed after the novel technique of deflation and early retrieval.

Persistent organic pollutants (POPs) are believed to alter metabolic homeostasis during fetal development, leading to childhood obesity. However, limited studies have explored how fetal chemical exposures relate to birth and infant weight outcomes in low-income Hispanic families at the highest risk of obesity. Therefore, we sought to determine associations between neonatal POPs exposure measured in newborn dried blood spots (DBS) and prenatal diet quality, birth weight, and overweight status at 18 months old. We conducted a case-control study nested within the Starting Early Program randomized controlled trial comparing POPs concentrations in infants with healthy weight (n = 46) and overweight status (n = 52) at age 18 months. Three categories of POPs, organochlorine pesticides (OCPs), polybrominated diphenyl ethers (PBDEs) and perfluoroalkyl substances (PFASs) were measured in archived newborn DBS. We assessed correlations between prenatal diet quality and neonatal POPs concentrations. Multivariable regression analyses examined associations between POPs (dichotomized at the mean) and birth weight z-score and weight status at 18 months, controlling for confounders. Seven of eight chemicals had detectable levels in greater than 94% of the sample. Higher protein, sodium and refined grain intake during pregnancy were correlated with lower POPs in newborn DBS. We found that high concentrations of perfluorooctanesulfonate (unstandardized coefficient [B]: -0.62, 95% confidence interval [CI]: -0.96 to -0.29) and perfluorohexanesulfate (B: -0.65, 95% CI: -0.99 to -0.31) were related to lower birth weight z-scores compared to those with low concentrations. We did not find associations between PBDEs, OCPs, and the other PFASs with birth weight z-scores, or between any POPs and weight status at 18 months. In conclusion, two PFASs were associated with lower birth weight, an important indicator of child health and growth, although direct associations with infant overweight status were not found. Whether neonatal POPs exposures contribute to economic and ethnic disparities in early obesity remains unclear.
