Introduction & Objectives: Gender composition within surgical academic leadership, including academic medical journals, disproportionately favors men. Disparities in journal leadership may introduce bias due to the familiar nature of reviewing and accepting academic publications. Genderrepresentation among academic urological journals' editorial boards has not yet been assessed. We evaluated female representation on editorialboards of urologic journals across multiple countries.Materials & Methods: Urologic journal leadership appointees' names and position descriptions were collected (from what pool? Did you surveyevery academic urology journal in the world?). Probable gender was obtained using gender-api.com or through personal title, as available. Journaleditorial positions were aggregated into broad leadership categories. Journal characteristics were summarized by Scimago Journal quartile (3 year,algorithmic weighted citation ranking) and geographic area. Chi-square test and multivariate logistic regression analysis were performed to assessfemale gender representation (p<0.05 significant).
Result(s): A total of 105 journals were reviewed with 5,991 total members: 877 (14.6%) female, 5,112 (85.3%) male and 2 (0.03%) non-binarypersons. Female representation significantly differed by leadership position, journal ranking, and geographic region. Editors-in-chief roles had thelowest female representation (48 females, 12.1%), while non-academic (32 females, 40.5%) and administrative (4 females, 80%) positions werehighest. Female representation, by journal ranking, was highest in Q1 (417 females, 19.4%) and lowest in Q3 (133 females, 8.9%) and by region,was highest in North American (323 females, 23.0%) and lowest in Asiatic region journals (55 females, 6.6%). On multivariate logistic regressionanalysis, Q1 journals had higher odds of female representation compared to Q2 and Q3. Additionally, compared to Western Europe, North Americanjournals had 78% higher odds and Asiatic journals had 50% lower odds of female representation (Fig 1).(Figure Presented)Conclusions: Female representation in urologic journal leadership is low across all journals, although trends in their proportion were identified by journal quartile and region. Addressing this gender imbalance may improve equal gender representation in journals and likely also improve female authored publication rates

PURPOSE/OBJECTIVE:Emergency department (ED) visits by patients with cancer frequently end in hospitalization. As concerns about ED and hospital crowding increase, observation unit care may be an important strategy to deliver safe and efficient treatment for eligible patients. In this investigation, we compared the prevalence and clinical characteristics of cancer patients who received observation unit care with those who were admitted to the hospital from the ED. METHODS:We performed a multicenter prospective cohort study of patients with cancer presenting to an ED affiliated with one of 18 hospitals of the Comprehensive Oncologic Emergency Research Network (CONCERN) between March 1, 2016 and January 30, 2017. We compared patient characteristics with the prevalence of observation unit care usage, hospital admission, and length of stay. RESULTS:Of 1,051 enrolled patients, 596 (56.7%) were admitted as inpatients, and 72 (6.9%) were placed in an observation unit. For patients admitted as inpatients, 23.7% had a length of stay ≤2 days. The conversion rate from observation to inpatient was 17.1% (95% CI 14.6-19.4) among those receiving care in an observation unit. The average observation unit length of stay was 14.7 hours. Patient factors associated ED disposition to observation unit care were female gender and low Charlson Comorbidity Index. CONCLUSION/CONCLUSIONS:In this multicenter prospective cohort study, the discrepancy between observation unit care use and short inpatient hospitalization may represent underutilization of this resource and a target for process change.

BACKGROUND:Untargeted plasma metabolomic profiling combined with machine learning (ML) may lead to discovery of metabolic profiles that inform our understanding of pediatric CKD causes. We sought to identify metabolomic signatures in pediatric CKD based on diagnosis: FSGS, obstructive uropathy (OU), aplasia/dysplasia/hypoplasia (A/D/H), and reflux nephropathy (RN). METHODS:: FSGS=63, OU=122, A/D/H=109, and RN=86). Lasso regression was used for feature selection, adjusting for clinical covariates. Four methods were then applied to stratify significance: logistic regression, support vector machine, random forest, and extreme gradient boosting. ML training was performed on 80% total cohort subsets and validated on 20% holdout subsets. Important features were selected based on being significant in at least two of the four modeling approaches. We additionally performed pathway enrichment analysis to identify metabolic subpathways associated with CKD cause. RESULTS:ML models were evaluated on holdout subsets with receiver-operator and precision-recall area-under-the-curve, F1 score, and Matthews correlation coefficient. ML models outperformed no-skill prediction. Metabolomic profiles were identified based on cause. FSGS was associated with the sphingomyelin-ceramide axis. FSGS was also associated with individual plasmalogen metabolites and the subpathway. OU was associated with gut microbiome-derived histidine metabolites. CONCLUSION:ML models identified metabolomic signatures based on CKD cause. Using ML techniques in conjunction with traditional biostatistics, we demonstrated that sphingomyelin-ceramide and plasmalogen dysmetabolism are associated with FSGS and that gut microbiome-derived histidine metabolites are associated with OU.

BACKGROUND:A contextual understanding of hypertension control can inform population health management strategies to mitigate cardiovascular disease events. This retrospective cohort study links neighborhood-level data with patients' health records to describe racial/ethnic differences in uncontrolled hypertension and determine if and to what extent these differences are mediated by neighborhood socioeconomic status (nSES). METHODS:We conducted a mediation analysis using a sample of patients with hypertension from 2 health care delivery systems in San Francisco over 2 years (n=47 031). We used generalized structural equation modeling, adjusted for age, sex, and health care system, to estimate the contribution of nSES to disparities in uncontrolled hypertension between White patients and Black, Hispanic/Latino, and Asian patients, respectively. Sensitivity analysis removed adjustment for health care system. RESULTS:Over half the cohort (62%) experienced uncontrolled hypertension during the study period. Racial/ethnic groups showed substantial differences in prevalence of uncontrolled hypertension and distribution of nSES quintiles. Compared with White patients, Black, and Hispanic/Latino patients had higher adjusted odds of uncontrolled hypertension: odds ratio, 1.79 [95% CI, 1.67-1.91] and odds ratio, 1.38 [95% CI, 1.29-1.47], respectively and nSES accounted for 7% of the disparity in both comparisons. Asian patients had slightly lower adjusted odds of uncontrolled hypertension when compared with White patients: odds ratio, 0.95 [95% CI, 0.89-0.99] and the mediating effect of nSES did not change the direction of the relationship. Sensitivity analysis increased the proportion mediated by nSES to 11% between Black and White patients and 13% between Hispanic/Latino and White patients, but did not influence differences between Asian and White patients. CONCLUSIONS:Among patients with hypertension in this study, nSES mediated a small proportion of racial/ethnic disparities in uncontrolled hypertension. Population health management strategies may be most effective by focusing on additional structural and interpersonal pathways such as racism and discrimination in health care settings.

This is the first real-world study to examine the association between a voluntary 16-ounce (oz) portion-size cap on sugar-sweetened beverages (SSB) at a sporting arena on volume of SSBs and food calories purchased and consumed during basketball games. Cross-sectional survey data from adults exiting a Brooklyn, NY, USA arena (Barclays, n = 464) with a 16-oz portion-size restriction and a Manhattan, NY, USA arena with no portion-size restriction (Madison Square Garden, control, n = 295) after the portion cap policy was put in place from March through June 2014 were analyzed. Linear regression models adjusting for sex, age, BMI, ethnicity, race, marital status, education, and income were used to compare the two arenas during the post-implementation period. The survey response rate was 45.9% and equivalent between venues. Among all arena goers, participants at Barclays purchased significantly fewer SSB oz (-2.24 oz, 95% CI [-3.95, -0.53], p = .010) and consumed significantly fewer SSB oz (-2.34 oz, 95% CI[-4.01, -0.68], p = .006) compared with MSG after adjusting for covariates. Among those buying at least one SSB, Barclays' participants purchased on average 11.03 fewer SSB oz. (95% CI = [4.86, 17.21], p < .001) and consumed 12.10 fewer SSB oz (95% CI = [5.78, 18.42], p < .001). There were no statistically significant differences between arenas in food calories and event satisfaction. In addition, no one reported not ordering a drink due to small size. An SSB portion-size cap was associated with purchasing and consuming fewer SSB oz. without evidence of decreasing satisfaction with the event experience.

BACKGROUND:Pregnant adolescent girls and young women (AGYW, aged 12-24 years) are at high risk for mental health problems, particularly in the Sub-Saharan African (SSA) region. METHODS:We performed a systematic review of mental health studies among pregnant AGYW in SSA published between January 1, 2007 and December 31, 2020 in PubMed, Embase, CINAHL, PsycInfo, and Global Index Medicus following PRISMA guidelines (PROSPERO: CRD42021230980). We used Bronfenbrenner's bioecological model to frame and synthesize results from included studies. FINDINGS/RESULTS: = 3). Studies reported life course factors, individual, microsystem, exosystem, macrosystem, and chronosystem-level factors associated with mental health problems. Gaps in mental health service delivery for pregnant AGYW included lack of confidentiality, judgmental healthcare worker attitudes, and lack of services tailored to their unique needs. INTERPRETATION/CONCLUSIONS:Gaps remain in research and services for mental health among pregnant AGYW in SSA. Integration of mental health services within school, community, and healthcare settings that are tailored to pregnant AGYW could strengthen health systems within SSA.
