Abstract
BACKGROUND In Australia, gynaecologists continue to assess and investigate abnormal uterine bleeding with inpatient hysteroscopy despite evidence validating outpatient hysteroscopy services. AIM This retrospective cohort study assessed the safety, success and acceptability of office hysteroscopy in a gynae-oncology rapid-access clinic over six years in Sydney, Australia, and included all women without an age or body mass index (BMI) cut-off using a 'see and treat' concept. METHODS A database was created and analysed retrospectively for patients who attended office hysteroscopy service between January 2016 and March 2021 (63 months, 481 eligible). An anonymous modified PAT-32 patient satisfaction questionnaire was also offered to an initial cohort after their procedure to gauge insightful feedback about acceptability. RESULTS A total of 92% of patients had successful outpatient hysteroscopic access; 24% of cases required hysteroscopy under general anaesthesia (GA) despite pathology in over 50% of cases; 68% of the total were able to be managed with outpatient hysteroscopy and did not require a follow-up GA hysteroscopy. This paper is also the first of its kind to our knowledge to incorporate patients >65 years, those with a BMI >35 and those with a history of cervical stenosis. This study suggests that age and BMI do not impact the success rate of the procedure. CONCLUSION This study demonstrates that outpatient hysteroscopy is an acceptable, safe procedure that is well tolerated by patients. Considering our rapid-access hysteroscopy service allowed 68% of the patient cohort to avoid hysteroscopy under GA, we estimate conservatively ~$63 million per year in Australia could be saved by performing office hysteroscopies.

Abstract
PURPOSE The majority of breast cancer patients are diagnosed with early-stage estrogen receptor (ER) positive disease. Despite effective treatments for these cancers, Black women have higher mortality than White women. We investigated demographic and clinical factors associated with receipt of chemotherapy among those with a discretionary indication who are at risk for overtreatment. METHODS Using Georgia Cancer Registry data, we identified females diagnosed with ER positive breast cancer who had a discretionary indication for chemotherapy (2010-2017). We used logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (CIs) associating patient demographic and clinical characteristics with chemotherapy initiation overall, and comparing non-Hispanic Black (NHB) with non-Hispanic White (NHW) women within strata of patient factors. RESULTS We identified 11,993 ER positive breast cancer patients with a discretionary indication for chemotherapy. NHB patients were more likely to initiate chemotherapy compared with NHW women (OR = 1.41, 95% CI: 1.28, 1.56). Race differences in chemotherapy initiation were pronounced among those who did not receive Oncotype DX testing (OR = 1.47, 95% CI: 1.31, 1.65) and among those residing in high socioeconomic status neighborhoods (OR = 2.48, 95% CI: 1.70, 3.61). However, we observed equitable chemotherapy receipt among patients who received Oncotype DX testing (OR = 0.90, 95% CI: 0.71, 1.14), were diagnosed with grade 1 disease (OR = 1.00, 95% CI: 0.74, 1.37), and those resided in rural areas (OR = 1.01, 95% CI: 0.76, 1.36). CONCLUSION We observed racial disparities in the initiation of chemotherapy overall and by sociodemographic and clinical factors, and more equitable outcomes when clinical guidelines were followed.

Abstract
Neighborhood deprivation indices are widely used in research, but the performance of these indices has rarely been directly compared in the same analysis. We examined the Area Deprivation Index, Neighborhood Deprivation Index, and Yost index, and compared their associations with breast cancer mortality. Indices were constructed for Georgia census block groups using 2011-2015 American Community Survey data. Pearson correlation coefficients and percent agreement were calculated. Associations between each index and breast cancer mortality were estimated among 36,795 women diagnosed with breast cancer using Cox proportional hazards regression. The indices were strongly correlated (absolute value of correlation coefficients > 0.77), exhibited moderate (41.4%) agreement, and were similarly associated with a 36% increase in breast cancer mortality. The similar associations with breast cancer mortality suggest the indices measure the same underlying construct, despite only moderate agreement. By understanding their correlations, agreement, and associations with health outcomes, researchers can choose the most appropriate index for analysis.

Abstract
BACKGROUND Research examining the effects of historical redlining on present-day health outcomes is often complicated by the misalignment of contemporary census boundaries with the neighborhood boundaries drawn by the US Home Owners' Loan Corporation (HOLC) in the 1930s. Previous studies have used different approaches to assign historical HOLC grades to contemporary geographies, but how well they capture redlining exposure is unknown. METHODS Our analysis included 7711 residences identified in the Multiple Listing Service database in Atlanta, Georgia (2017-2022). We evaluated the classification of HOLC grade assignment (A, B, C, D, or ungraded) when assigning exposure under four area-level approaches (centroid, majority land area, weighted score, and highest HOLC) compared with using complete address data (gold standard). We additionally compared approaches across three 2020 census geographies (tract, block group, and block). RESULTS When comparing the use of census tracts to complete address data, sensitivity was highest for the weighted score approach, which correctly identified 77% of residences in truly A-D graded neighborhoods as compared with the majority land area (44%), centroid (54%), and highest HOLC (59%) approaches. Regarding specificity, the majority land area approach best-classified residences in truly ungraded neighborhoods (93%) as compared with the weighted score (65%), centroid (81%), and highest HOLC (54%) approaches. Classification improved regardless of approach when using census block compared with the census tract. CONCLUSIONS Misclassification of historical redlining exposure is inevitable when using contemporary census geographies rather than complete address data. This study provides a framework for assessing spatial misalignment and selecting an approach for classification.

Abstract
PURPOSE The 'DSD Pathways' study was initiated to assess health status and patterns of care among people enrolled in large integrated healthcare systems and diagnosed with conditions comprising the broad category of disorders (differences) of sex development (DSD). The objectives of this communication are to describe methods of cohort ascertainment for two specific DSD conditions-classic congenital adrenal hyperplasia with 46,XX karyotype (46,XX CAH) and complete androgen insensitivity syndrome (CAIS). PARTICIPANTS Using electronic health records we developed an algorithm that combined diagnostic codes, clinical notes, laboratory data and pharmacy records to assign each cohort candidate a 'strength-of-evidence' score supporting the diagnosis of interest. A sample of cohort candidates underwent a review of the full medical record to determine the score cutoffs for final cohort validation. FINDINGS TO DATE Among 5404 classic 46,XX CAH cohort candidates the strength-of-evidence scores ranged between 0 and 10. Based on sample validation, the eligibility cut-off for full review was set at the strength-of-evidence score of ≥7 among children under the age of 8 years and ≥8 among older cohort candidates. The final validation of all cohort candidates who met the cut-off criteria identified 115 persons with classic 46,XX CAH. The strength-of-evidence scores among 648 CAIS cohort candidates ranged from 2 to 10. There were no confirmed CAIS cases among cohort candidates with scores <6. The in-depth medical record review for candidates with scores ≥6 identified 61 confirmed cases of CAIS. FUTURE PLANS As the first cohort of this type, the DSD Pathways study is well-positioned to fill existing knowledge gaps related to management and outcomes in this heterogeneous population. Analyses will examine diagnostic and referral patterns, adherence to care recommendations and physical and mental health morbidities examined through comparisons of DSD and reference populations and analyses of health status across DSD categories.

Abstract
BACKGROUND The authors identified tumor, treatment, and patient characteristics that may contribute to differences in breast cancer (BC) mortality by race, rurality, and area-level socioeconomic status (SES) among women diagnosed with stage IIIB-IV BC in Georgia. METHODS Using the Georgia Cancer Registry, 3084 patients with stage IIIB-IV primary BC (2013-2017) were identified. Cox proportional hazards regression was used to calculate the hazard ratios (HRs) and 95% confidence intervals (CIs) comparing mortality among non-Hispanic Black (NHB) versus non-Hispanic White (NHW), residents of rural versus urban neighborhoods, and residents of low- versus high-SES neighborhoods by tumor, treatment, and patient characteristics. The mediating effects of specific characteristics on the association between race and BC mortality were estimated. RESULTS Among the study population, 41% were NHB, 21% resided in rural counties, and 72% resided in low SES neighborhoods. The authors observed mortality disparities by race (HR, 1.27; 95% CI, 1.13, 1.41) and rurality (HR, 1.14; 95% CI, 1.00, 1.30), but not by SES (HR, 1.04; 95% CI, 0.91, 1.19). In the stratified analyses, racial disparities were the most pronounced among women with HER2 overexpressing tumors (HR, 2.30; 95% CI, 1.53, 3.45). Residing in a rural county was associated with increased mortality among uninsured women (HR, 2.25; 95% CI, 1.31, 3.86), and the most pronounced SES disparities were among younger women (<40 years: HR, 1.46; 95% CI, 0.88, 2.42). CONCLUSIONS There is considerable variation in racial, regional, and socioeconomic disparities in late-stage BC mortality by tumor, treatment, and patient characteristics.

Abstract
BACKGROUND Menstrual cycle characteristics-including age at menarche and cycle length- have been associated with ovarian cancer risk in White women. However, the associations between menstrual cycle characteristics and ovarian cancer risk among Black women have been sparsely studied. METHODS Using the Ovarian Cancer in Women of African Ancestry (OCWAA) Consortium that includes 1,024 Black and 2,910 White women diagnosed with epithelial ovarian cancer (EOC) and 2,325 Black and 7,549 White matched controls, we investigated associations between menstrual cycle characteristics (age at menarche, age at menstrual regularity, cycle length, and ever missing three periods) and EOC risk by race and menopausal status. Multivariable logistic regression was used to calculate odds ratios (OR) and 95% confidence intervals (CI). RESULTS Black women were more likely to be <11 years at menarche than White women (controls: 9.9% vs. 6.0%). Compared with ≥15 years at menarche, <11 years was associated with increased EOC risk for White (OR = 1.25; 95% CI, 0.99-1.57) but not Black women (OR = 1.10; 95% CI, 0.80-1.55). Among White women only, the association was greater for premenopausal (OR = 2.20; 95% CI, 1.31-3.68) than postmenopausal women (OR = 1.06; 95% CI, 0.82-1.38). Irregular cycle length was inversely associated with risk for White (OR = 0.78; 95% CI, 0.62-0.99) but not Black women (OR = 1.06; 95% CI, 0.68-1.66). CONCLUSIONS Earlier age at menarche and cycle irregularity are associated with increased EOC risk for White but not Black women. IMPACT Associations between menstrual cycle characteristics and EOC risk were not uniform by race.

Abstract
Abstract
Despite an overall decline in breast cancer (BC) mortality due to advancements in cancer therapy, mortality disparities by race, rurality, and socioeconomic status (SES) persist among women diagnosed with metastatic disease in the US. Women residing in high-poverty or rural areas or who are non-Hispanic Black (NHB) experience higher rates of BC mortality relative to their counterparts. Although mortality disparities among late-stage BC patients are well-documented, few studies have examined the drivers of these disparities, which are likely multifactorial. We sought to identify tumor, treatment, and patient characteristics that may contribute to differences in BC mortality by race, rurality, and SES among women diagnosed with a first primary stage IIIB - IV BC in Georgia.Using the Georgia Cancer Registry, we identified 3085 patients with an initial diagnosis of stage IIIB-IV primary BC between January 2013 and December 2017. Cox proportional hazards regression was used to calculate the hazard ratios (HRs) and 95% confidence intervals (CIs) to compare NHB vs. non-Hispanic White (NHW), rural vs. urban residents, and residents of low- vs. high-SES neighborhoods by tumor (stage, grade, ER status, and molecular subtype), treatment (surgery type, receipt of chemotherapy, radiation, hormonal, neoadjuvant, and immunotherapy), and patient (race, insurance, age group, marital status, region, SES) characteristics. Using an extension of the counterfactual framework, we estimated the mediating effects of subtype, stage, SES, rurality, and insurance on the association between race and BC mortality. Among the study population, 41% were NHB, 21% resided in rural counties, and 72% resided in low SES neighborhoods. Overall, we observed mortality disparities by race (HR=1.27, 95% CI: 1.13, 1.41) and rurality (HR=1.14, 95% CI: 1.00, 1.30), but not by SES (HR=1.04, 95% CI: 0.91, 1.19). In the stratified analyses, racial disparities were the most pronounced among women with HER2 overexpressing tumors (HR=2.30, 95% CI: 1.53, 3.45). Residing in a rural neighborhood was associated with increased mortality among uninsured women (HR=2.25, 95% CI: 1.31, 3.86) or receipt of breast-conserving surgery (HR=2.21, 95 CI%: 1.32, 3.71). The most pronounced socioeconomic disparities were among younger women (<40 years: HR=1.46, 95% CI: 0.88, 2.42) and patients who received neoadjuvant therapy (HR=1.44, 95% CI: 1.01, 2.05). The mediation analysis demonstrated that 48% of the effect between race and BC mortality was mediated by subtype.There is considerable variation in racial, regional, and socioeconomic disparities in metastatic BC mortality by tumor, treatment, and patient characteristics. For each, we’ve identified patient groups where disparities are most pronounced. Understanding specific barriers within these patient groups will inform future interventions aimed at reducing disparities in metastatic BC mortality.

Abstract
In the US, breast cancer mortality is 40% greater among Black than White women. The mortality disparity varies geographically and has persisted despite improvements in survival. Georgia is one of six states where breast cancer recently surpassed lung cancer as the leading cause of cancer death among Black but not White women, is a large and diverse state, and thus, an ideal setting to study race disparities. Our work in the Atlanta Metro area has shown that the mortality disparity is pronounced among patients with clinically favorable subtypes, low Oncotype DX® recurrence scores, guideline-concordant care, and similar access to surgical facilities. The disparity also persists among patients with private insurance and those living in areas of low poverty, suggesting clinical and sociodemographic differences do not fully account for the observed disparity. Recent evidence suggests area-level factors may contribute to the disparity. Our group reported that neighborhood-level redlining (i.e., mortgage denial based on place) is associated with an increase in breast cancer mortality while neighborhood-level lending bias (i.e., mortgage denial based on race) is associated with a decrease in breast cancer mortality. In Atlanta, Black patients are more likely to live in redlined areas and less likely to live in areas with lending bias, than White patients, further suggesting place is an important driver of disparities. We investigated the role of other area-level factors on race-specific mortality in Georgia. Race-specific standardized mortality ratios were computed for each county in Georgia. Observed breast cancer deaths among non-Hispanic White (NHW) and non-Hispanic Black (NHB) women within 5 years of a stage I-III breast cancer diagnosis (2005-2013) were obtained from the Georgia Cancer Registry. County-level characteristics were derived from the American Community Survey and Georgia Department of Public Health. A Bayesian model-based approach was used to stabilize local estimates and estimate associations with area-level factors. Smoothed estimates of relative disparity ranged from 1.2 to 1.7, with pronounced disparity for counties surrounding the Atlanta and Savannah metropolitan areas and least pronounced disparity in Metro Albany counties. Among NHB women, living in a rural (versus non-rural) county was associated with a nearly 20% increase in breast cancer mortality (RR=1.19, 95% credible interval (CI): 0.96, 1.48); an association not observed in NHW patients (RR=0.93, 95% CI: 0.79, 1.07). In contrast, a 10-point increase in the percent of adults with ≤high school education was associated with a 10% increase (95% CI: 1.05, 1.17) in mortality for NHW patients only. The race disparity in Georgia is not evenly distributed across counties. We identified area-level characteristics associated with race-specific mortality. Identifying other area-level drivers of breast cancer mortality is an important area of inquiry.

Abstract
BACKGROUND Black women are more likely to die of breast cancer than White women. This study evaluated the contribution of time to primary surgical management and surgical facility characteristics to racial disparities in breast cancer mortality among both Black and White women. METHODS The study identified 2224 Black and 3787 White women with a diagnosis with stages I to III breast cancer (2010-2014). Outcomes included time to surgical treatment (> 30 days from diagnosis) and breast cancer mortality. Odds ratios (ORs) and 95% confidence intervals (CIs) associating surgical facility characteristics with surgical delay were computed, and Cox proportional hazards regression was used to compute hazard ratios (HRs) and 95% CIs associating delay and facility characteristics with breast cancer mortality. RESULTS Black women were two times more likely to have a surgical delay (OR, 2.15; 95% CI, 1.92-2.41) than White women. Racial disparity in surgical delay was least pronounced among women treated at a non-profit facility (OR, 1.95; 95% CI, 1.70-2.25). The estimated mortality rate for Black women was two times that for White women (HR, 2.00; 95% CI, 1.83-2.46). Racial disparities in breast cancer mortality were least pronounced among women who experienced no surgical delay (HR, 1.81; 95% CI, 1.28-2.56), received surgery at a government facility (HR, 1.31; 95% CI, 0.76-2.27), or underwent treatment at a Commission on Cancer-accredited facility (HR, 1.82; 95% CI, 1.38-2.40). CONCLUSIONS Black women were more likely to experience a surgical delay and breast cancer death. Persistent racial disparities in breast cancer mortality were observed across facility characteristics except for government facilities.

Abstract
BACKGROUND Gastrointestinal (GI) cancers represent a diverse group of diseases. We assessed differences in geographic and racial disparities in cancer-specific mortality across subtypes, overall and by patient characteristics, in a geographically and racially diverse US population. METHODS Clinical, sociodemographic, and treatment characteristics for patients diagnosed during 2009-2014 with colorectal cancer (CRC), pancreatic cancer, hepatocellular carcinoma (HCC), or gastric cancer in Georgia were obtained from the Surveillance, Epidemiology, and End Results Program database. Patients were classified by geography (rural or urban county) and race and followed for cancer-specific death. Multivariable Cox proportional hazards models were used to calculate stratified hazard ratios (HR) and 95% confidence intervals (CIs) for associations between geography or race and cancer-specific mortality. RESULTS Overall, 77% of the study population resided in urban counties and 33% were non-Hispanic Black (NHB). For all subtypes, NHB patients were more likely to reside in urban counties than non-Hispanic White patients. Residing in a rural county was associated with an overall increased hazard of cancer-specific mortality for HCC (HR = 1.15, 95% CI = 1.02-1.31), pancreatic (HR = 1.11, 95% CI = 1.03-1.19), and gastric cancer (HR = 1.17, 95% CI = 1.03-1.32) but near-null for CRC. Overall racial disparities were observed for CRC (HR = 1.18, 95% CI = 1.11-1.25) and HCC (HR = 1.12, 95% CI = 1.01-1.24). Geographic disparities were most pronounced among HCC patients receiving surgery. Racial disparities were pronounced among CRC patients receiving any treatment. CONCLUSION Geographic disparities were observed for the rarer GI cancer subtypes, and racial disparities were pronounced for CRC. Treatment factors appear to largely drive both disparities.

Abstract
BACKGROUND Risk of type 2 diabetes mellitus (T2DM) in transgender and gender diverse (TGD) persons, especially those receiving gender-affirming hormone therapy (GAHT) is an area of clinical and research importance. METHODS We used data from an electronic health record-based cohort study of persons 18 years and older enrolled in 3 integrated health care systems. The cohort included 2869 transfeminine members matched to 28 300 cisgender women and 28 258 cisgender men on age, race/ethnicity, calendar year, and site, and 2133 transmasculine members similarly matched to 20 997 cisgender women and 20 964 cisgender men. Cohort ascertainment spanned 9 years from 2006 through 2014 and follow-up extended through 2016. Data on T2DM incidence and prevalence were analyzed using Cox proportional hazards and logistic regression models, respectively. All analyses controlled for body mass index. RESULTS Both prevalent and incident T2DM was more common in the transfeminine cohort relative to cisgender female referents with odds ratio and hazard ratio (95% CI) estimates of 1.3 (1.1-1.5) and 1.4 (1.1-1.8), respectively. No significant differences in prevalence or incidence of T2DM were observed across the remaining comparison groups, both overall and in TGD persons with evidence of GAHT receipt. CONCLUSION Although transfeminine people may be at higher risk for T2DM compared with cisgender females, the corresponding difference relative to cisgender males is not discernable. Moreover, there is little evidence that T2DM occurrence in either transfeminine or transmasculine persons is attributable to GAHT use.

Abstract
Background Adoption of molecular techniques to detect Plasmodium falciparum infection has revealed many previously undetected (by microscopy) yet transmissible low-density infections. The proportion of these infections is typically highest in low transmission settings, but drivers of submicroscopic infection remain unclear. Here, we updated a previous systematic review of asexual P falciparum prevalence by microscopy PCR in the same population. We aimed to explore potential drivers of submicroscopic infection and to identify the locations where submicroscopic infections are most common. Methods In this systematic review and meta-analysis we searched PubMed and Web of Science from Jan 1, 2010, until Oct 11, 2020, for cross-sectional studies reporting data on asexual P falciparum prevalence by both microscopy and PCR. Surveys of pregnant women, surveys in which participants had been chosen based on symptoms or treatment, or surveys that did not involve a population from a defined location were excluded. Both the number of individuals tested and the number of individuals who tested positive by microscopy or PCR, or both, for P falciparum infection were extracted. Bayesian regression modelling was used to explore determinants of the size of the submicroscopic reservoir including geographical location, seasonality, age, methodology, and current or historical patterns of transmission. Findings Of 4893 identified studies, we retained 121 after screening and removal of duplicates. 45 studies from a previous systematic review were included giving 166 studies containing 551 cross-sectional survey microscopy and PCR prevalence pairs. Our results show that submicroscopic infections predominate in low-transmission settings across all regions, but also reveal marked geographical variation, with the proportion of infections that are submicroscopic being highest in South American surveys and lowest in west African surveys. Although current transmission levels partly explain these results, we find that historical transmission intensity also represents a crucial determinant of the size of the submicroscopic reservoir, as does the demographic structure of the infected population (with submicroscopic infection more likely to occur in adults than in children) and the PCR or microscopy methodology used. We also observed a small yet significant influence of seasonality, with fewer submicroscopic infections observed in the wet season than the dry season. Integrating these results with estimates of infectivity in relation to parasite density suggests the contribution of submicroscopic infections to transmission across different settings is likely to be highly variable. Interpretation Significant variation in the prevalence of submicroscopic infection exists even across settings characterised by similar current levels of transmission. These differences in submicroscopic epidemiology potentially warrant different approaches to targeting this infected subgroup across different settings to eliminate malaria.

Abstract
PURPOSE Early diagnosis is fundamental to reducing breast cancer (BC) mortality, and understanding potential barriers from initial screening to confirmed diagnosis is essential. The aim of this study was to evaluate patient characteristics that contribute to delay in diagnosis of screen-detected cancers and the contribution of delay to tumor characteristics and BC mortality. METHODS Three hundred sixty-two White and 368 Black women were identified who were screened and received subsequent BC diagnoses within Emory Healthcare, a part of Emory University health care system (2010-2014). Multivariable-adjusted logistic regression was used to calculate the odds ratios (ORs) and 95% confidence intervals (CIs) associating patient characteristics with delay to diagnostic evaluation (≥30 versus <30 days), delay to biopsy (≥15 versus <15 days), and total delay (≥45 versus <45 days). Additionally, the ORs and 95% CIs associating delay with tumor characteristics and BC mortality were computed. RESULTS Black women and women diagnosed at later stages, with larger tumor sizes, and with triple-negative tumors were more likely to experience ≥45 days to diagnosis. In multivariable-adjusted models, Black women had at least a two-fold increase in the odds of delay to diagnostic evaluation (OR, 1.98; 95% CI, 1.45-2.71), biopsy delays (OR, 2.41; 95% CI, 1.67-3.41), and total delays ≥45 days (OR, 2.22; 95% CI, 1.63-3.02) compared with White women. A 1.6-fold increased odds of BC mortality was observed among women who experienced total delays ≥45 days compared with women without delays in diagnosis (OR, 1.57, 95% CI, 0.96-2.58). CONCLUSIONS The study demonstrated racial disparities in delays in the diagnostic process for screen-detected malignancies. Total delay in diagnosis was associated with an increase in BC mortality.

Abstract
BACKGROUND AND OBJECTIVES The progression of gender-expansive behavior to gender dysphoria and to gender-affirming hormonal treatment (GAHT) in children and adolescents is poorly understood. METHODS A cohort of 958 gender-diverse (GD) children and adolescents who did not have a gender dysphoria-related diagnosis (GDRD) or GAHT at index were identified. Rates of first GDRD and first GAHT prescription were compared across demographic groups. RESULTS Overall, 29% of participants received a GDRD and 25% were prescribed GAHT during the average follow-up of 3.5 years (maximum 9 years). Compared with youth assigned male sex at birth, those assigned female sex at birth were more likely to receive a diagnosis and initiate GAHT with hazard ratio (95% confidence interval) estimates of 1.3 (1.0-1.7), and 2.5 (1.8-3.3), respectively. A progression to diagnosis was more common among those aged ≥15 years at initial presentation compared with those aged 10 to 14 years and those aged 3 to 9 years (37% vs 28% vs 16%, respectively). By using the youngest group as a reference, the adjusted hazard ratios (95% confidence interval) for a GDRD were 2.0 (1.3-3.0) for age 10 to 14 years and 2.7 (1.8-3.9) for age ≥15 years. Racial and ethnic minorities were less likely to receive a diagnosis or be prescribed GAHT. CONCLUSIONS This study characterized the progression of GD behavior in children and adolescents. Less than one-third of GD youth receive an eventual GDRD, and approximately one-quarter receive GAHT. Female sex at birth, older age of initial GD presentation to medical care, and non-Hispanic white race and ethnicity increased the likelihood of receiving diagnosis and treatment.

Abstract
OBJECTIVE To examine temporal changes in the number and demographic composition of transgender/gender non-binary (TGNB) population using data from integrated health care systems. METHODS Electronic health records from Kaiser Permanente health plans in Georgia and Northern and Southern California were used to identify TGNB individuals, who sought care from January 2006 to December 2014, and the data were analyzed by year, site, age, and sex assigned at birth. RESULTS In 2006, the number of TGNB people (and corresponding 95% CI) per 100 000 population were 3.5 (1.9, 6.3) in Georgia, 5.5 (4.8, 6.4) in Southern California, and 17 (16, 19) in Northern California. In 2014, these frequencies increased to 38 (32, 45), 44 (42, 46), and 75 (72, 78) per 100 000 population, respectively. When analyzed by age, the most rapid increase was observed among persons 18 to 25 years old, and this increase accelerated after 2010. The ratio of transmasculine to transfeminine persons also changed from 1:1.7 in 2006 to 1:1 in 2014 overall and from 1:1 in 2006 to 1.8:1 in 2014 among persons <18 years of age. CONCLUSION This analysis confirms previous observations that the proportion of TGNB people is growing, especially among young adults. The composition of the TGNB population is also changing from predominantly transfeminine to roughly 1:1 overall and to predominantly transmasculine in children and adolescents.

Abstract
BACKGROUND Structural inequities have important implications for the health of marginalized groups. Neighborhood-level redlining and lending bias represent state-sponsored systems of segregation, potential drivers of adverse health outcomes. We sought to estimate the effect of redlining and lending bias on breast cancer mortality and explore differences by race. METHODS Using Georgia Cancer Registry data, we included 4,943 non-Hispanic White (NHW) and 3,580 non-Hispanic Black (NHB) women with a first primary invasive breast cancer diagnosis in metro-Atlanta (2010-2014). Redlining and lending bias were derived for census tracts using the Home Mortgage Disclosure Act database. We calculated hazard ratios and 95% confidence intervals (CI) for the associations of redlining, lending bias on breast cancer mortality and estimated race-stratified associations. RESULTS Overall, 20% of NHW and 80% of NHB women lived in redlined census tracts, and 60% of NHW and 26% of NHB women lived in census tracts with pronounced lending bias. Living in redlined census tracts was associated with a nearly 1.60-fold increase in breast cancer mortality (hazard ratio = 1.58; 95% CI, 1.37-1.82) while residing in areas with substantial lending bias reduced the hazard of breast cancer mortality (hazard ratio = 0.86; 95% CI, 0.75-0.99). Among NHB women living in redlined census tracts, we observed a slight increase in breast cancer mortality (hazard ratio = 1.13; 95% CI, 0.90-1.42); among NHW women the association was more pronounced (hazard ratio = 1.39; 95% CI, 1.09-1.78). CONCLUSIONS These findings underscore the role of ecologic measures of structural racism on cancer outcomes. IMPACT Place-based measures are important contributors to health outcomes, an important unexplored area that offers potential interventions to address disparities.

Abstract
Abstract
Background: Cancers of the gastrointestinal system represent a diverse range of diseases with different etiologies, from screening-detectable colorectal cancer (CRC) to pancreatic cancer, often diagnosed at late stage and highly lethal. While racial disparities have been observed for some of these cancers, the impact of geography is less understood. Georgia is an ideal place to examine disparities in geography because it has a diverse setting and population, with approximately 25% of residents living in a rural area and nearly one-third identifying as non-Hispanic Black (NHB), according to the 2010 decennial census. Methods: We obtained clinical (age at diagnosis, tumor stage, tumor size), sociodemographic (e.g., insurance status, marital status, SES index), and treatment information (e.g., receipt of surgery, lymph node biopsy/removal) on nearly 30,000 NHB and non-Hispanic White (NHW) men and women aged 18 years and older, diagnosed with CRC, hepatocellular carcinoma (HCC), pancreatic cancer or gastric cancer between 2009 and 2014 in Georgia from the population-based Surveillance, Epidemiology, and End Results (SEER) Program.
Patients were classified as residing in a metro or non-metro county at diagnosis according to 2013 rural-urban continuum codes. Multivariable Cox proportional hazards models were used to calculate the hazard ratios (HRs) and corresponding 95% confidence intervals (95% CI) for the association between residing in a non- metro versus metro county and cause-specific mortality, stratified by patient characteristics. Results: Over 75% of the study population resided in a metro county at diagnosis, with the highest proportion among HCC cases (81%) and the lowest proportion among CRC cases (76%). Overall, NHBs were more likely to reside in metro counties (82%) than NHWs (74%). The average length of follow-up varied by cancer site and metro status, ranging from 35 months (CRC in metro areas) to 4 months (pancreatic cancer in non-metro areas). For all cancer sites, patients in metro counties were more likely to be younger, single, have localized disease (except gastric cancer), and receive surgery of the primary site. By comparison, patients in non-metro counties were more likely to be diagnosed at older ages, have Medicaid, and be widowed. Residing in a non-metro county was associated with higher cause- specific mortality among the youngest patients (age 18-49 years) for pancreatic cancer (HR=1.4, 95% CI: 1.1, 1.9) and gastric cancer (HR=1.8, 95% CI: 1.2, 2.6). We also observed a higher hazard of mortality for residing in a non-metro compared to metro county among NHB HCC patients (HR=1.3, 95% CI: 1.0, 1.7) and never married gastric cancer patients (HR=1.5, 95% CI: 1.1, 2.1). Associations among CRC patients were less robust. Conclusion: Our results suggest residing in a non-metro county is associated with higher mortality among some groups diagnosed with rarer gastrointestinal cancers. Geographic differences in access to diagnosis and treatment may contribute to this disparity.

Abstract
Accurate identification of transgender persons is a critical first step in conducting transgender health studies. To develop an automated algorithm for identifying transgender individuals from electronic medical records (EMR) using free-text clinical notes. The development and validation of the algorithm was based on data from an integrated healthcare system that served as a participating site in the multicenter Study of Transition Outcomes and Gender. The training and test datasets each contained a total of 300 individuals identified between 2006 and 2014. Both datasets underwent a full medical record review by experienced research abstractors. The validated algorithm was then implemented to identify transgender individuals in the EMR using all clinical notes of patients that received care between January 1, 2015 and June 30, 2018. Validation of the algorithm against the full chart review demonstrated a high degree of accuracy with 97% sensitivity, 95% specificity, 94% positive predictive value, and 97% negative predictive value. The algorithm classified 7,409 individuals (3.5%) as "Definitely transgender" and 679 individuals (0.3%) as "Probably transgender" out of 212,138 candidates with a total of 378,641 clinical notes. The computerized NLP algorithm can support essential efforts to improve the health of transgender people.

Abstract
The goal of health professional education programs is to produce competent graduates, with an ability to work collaboratively as effective healthcare team members. We explored the reflections of students and clinical facilitators, in response to participation in a structured interprofessional education (IPE) clinical placement program. In our qualitative study we used an exploratory case study design. In our analysis, we highlight the benefits of interprofessional practice. Key themes identified by students included: limited opportunities to engage in IPE across their course; lack of clarity around IPE; value of IPE for students, practitioners, and patient outcomes; and need for IPE opportunities to be integrated into placements. Key themes identified by the clinical facilitators included: being reminded of the value of IPE for students and patients; preparation for IPE placements need to be embedded in curricula; coordination and communication of IPE learning activities need to be clear for staff and students; and IPE should continue as part of the broader clinical education agenda. Our findings reinforce the notion that students and clinical facilitators value the importance of IPE for student learning within the clinical placement setting. The outcomes offer valuable insights for universities and hospital and health care contexts for setting up and implementing IPE activities, and we provide recommendations for improving ongoing IPE efforts within clinical placement setting.

Abstract
CONTEXT The effect of gender-affirming hormone therapy (HT) on erythropoiesis is an area of priority in transgender health research. OBJECTIVE To compare changes in hematologic parameters and rates of erythrocytosis and anemia among transgender people to those of cisgender controls. DESIGN Longitudinal observational study. PARTICIPANTS AND SETTING We compared 559 transfeminine (TF) and 424 transmasculine (TM) people enrolled in 3 integrated health care systems to matched cisgender referents. INTERVENTIONS AND OUTCOME Hormone therapy receipt was ascertained from filled prescriptions. Hemoglobin (Hb) and hematocrit (Hct) levels were examined from the first blood test to HT initiation, and from the start of HT to the most recent blood test. Rates of erythrocytosis and anemia in transgender participants and referents were compared by calculating adjusted hazard ratios and 95% confidence intervals (CI). RESULTS In the TF group, there was a downward trend for both Hb and Hct. The corresponding changes in the TM cohort were in the opposite direction. TM study participants experienced a 7-fold higher rate (95% CI: 4.1-13.4) of erythrocytosis relative to matched cisgender males, and an 83-fold higher rate (95% CI: 36.1-191.2) compared to cisgender females. The corresponding rates for anemia were elevated in TF subjects but primarily relative to cisgender males (hazard ratio 5.9; 95% CI: 4.6-7.5). CONCLUSIONS Our results support previous recommendations that hematological parameters of transgender people receiving HT should be interpreted based on their affirmed gender, rather than their sex documented at birth. The clinical significance of erythrocytosis following testosterone therapy, as well as anemia following feminizing HT, requires further investigation.

Abstract
INTRODUCTION Transgender and gender diverse people often face discrimination and may experience disproportionate emotional distress that leads to suicide attempts. Therefore, it is essential to estimate the frequency and potential determinants of suicide attempts among transgender and gender diverse individuals. METHODS Longitudinal data on 6,327 transgender and gender diverse individuals enrolled in 3 integrated healthcare systems were analyzed to assess suicide attempt rates. Incidence was compared between transmasculine and transfeminine people by age and race/ethnicity and according to mental health status at baseline. Cox proportional hazards models examined rates and predictors of suicide attempts during follow-up. Data were collected in 2016, and analyses were conducted in 2019. RESULTS During follow-up, 4.8% of transmasculine and 3.0% of transfeminine patients had at least 1 suicide attempt. Suicide attempt rates were more than 7 times higher among patients aged <18 years than among those aged >45 years, more than 3 times higher among patients with previous history of suicide ideation or suicide attempts than among those with no such history, and 2-5 times higher among those with 1-2 mental health diagnoses and more than 2 mental health diagnoses at baseline than among those with none. CONCLUSIONS Among transgender and gender diverse individuals, younger people, people with previous suicidal ideation or attempts, and people with multiple mental health diagnoses are at a higher risk for suicide attempts. Future research should examine the impact of gender-affirming healthcare use on the risk of suicide attempts and identify targets for suicide prevention interventions among transgender and gender diverse people in clinical settings.

Abstract
PURPOSE The aim of the study was to assess the contemporary presentation and management of subglottic cysts and make recommendations on the treatment of these patients. METHODS Retrospective case series of 105 patients between October 1999 and November 2017 from a paediatric teaching hospital. RESULTS Ninety-one percentage (n = 96) had a history of prematurity, with a mean gestation of 27.2 weeks (SD ± 4.1). A history of intubation was found in 99% (n = 104) of cases [median 18 days (range = 1-176)]. Presenting symptoms were: Stridor 57.1%, (n = 60), difficult intubation 14% (n = 15), recurrent croup 11.4% (n = 12), failed extubation 7.6%, (n = 8), hoarseness/weak cry 10.5% (n = 10). Ninety percentage (n = 94) underwent intervention for management of SGCs with 86% (n = 81) treated with cold steel marsupialisation and 14% (n = 13) with CO 2 laser. Recurrent cysts occurred in 56% (n = 53) of cases. Treatment modality did not affect recurrence (p = 0.594 Δ). Sixty-six percentage (n = 69/105) of patients had one or more concurrent airway pathology at MLB. Most frequent was subglottic stenosis 47% (n = 49), with 16% (n = 8) subsequently requiring open reconstructive airway surgery. Mean duration of follow-up was 47.6 months (SD ± 38.3). CONCLUSION SGC are an uncommon, reversible cause of upper airway obstruction and should be considered in the list of differential diagnoses in patients with a history of prematurity and perinatal intubation, presenting with stridor. While concurrent SGS is common, adequate symptom improvement in such cases may be achieved with SGC removal alone. Management is by surgical marsupialisation. Recurrence and additional airway pathologies are common and may necessitate longer-term treatment in centres with paediatric airway expertise.

Abstract
BACKGROUND Visual conformity with affirmed gender (VCAG) or "passing" is thought to be an important, but poorly understood, determinant of well-being in transgender people. VCAG is a subjective measure that is different from having an inner sense of being congruent with one's gender identity. AIM We examined the frequency and determinants of VCAG and explored its association with mental health outcomes in a cohort of transgender adults. METHODS The "Study of Transition, Outcomes & Gender (STRONG)" is a cohort of transgender individuals recruited from 3 Kaiser Permanente health plans located in Georgia, Northern California and Southern California. A subset of cohort members completed a survey between 2015 and 2017. VCAG was assessed as the difference between 2 scales: scale 1 reflecting the person's sense of how they are perceived by others, and scale 2 reflecting the person's desire to be perceived. Participants were considered to have achieved VCAG when their scale 1 scores were equal to or exceeded their scale 2 scores. The frequency of VCAG and their independent associations with anxiety and depression symptoms were explored using data from 620 survey respondents including 309 transwomen and 311 transmen. Based on self-described gender identity, none of the participants identified as nonbinary or gender fluid. OUTCOMES VCAG, depression, and anxiety. RESULTS VCAG was achieved in 28% of transwomen and 62% of transmen and was more common in persons who reported greater sense of acceptance and pride in their gender identity as measured on the Transgender Congruence Scale. Another factor associated with greater likelihood of VCAG was receipt of gender-affirming surgery, but the association was only evident among transmen. Participants who achieved VCAG had a lower likelihood of depression and anxiety with prevalence ratios (95% confidence intervals) of 0.79 (0.65, 0.96) and 0.67 (0.46, 0.98), respectively. CLINICAL IMPLICATIONS VCAG may serve as an important outcome measure after gender-affirming therapy. STRENGTHS AND LIMITATIONS Strengths of this study include a well-defined sampling frame and use of a novel patient-centered outcome of interest. Cross-sectional design and uncertain generalizability of results are the limitations. CONCLUSION These results, once confirmed by prospective studies, may help better characterize the determinants of well-being in the transgender community, facilitating the design of interventions to improve the well-being and quality of life of this vulnerable population.

Abstract
BACKGROUND Tamoxifen and its metabolites compete with estrogen to occupy the estrogen receptor. The conventional dose of adjuvant tamoxifen overwhelms estrogen in this competition, reducing breast cancer recurrence risk by nearly half. Phase I metabolism generates active tamoxifen metabolites, and phase II metabolism deactivates them. No earlier pharmacogenetic study has comprehensively evaluated the metabolism and transport pathways, and no earlier study has included a large population of premenopausal women. METHODS We completed a cohort study of 5,959 Danish nonmetastatic premenopausal breast cancer patients, in whom 938 recurrences occurred, and a case-control study of 541 recurrent cases in a cohort of Danish predominantly postmenopausal breast cancer patients, all followed for 10 years. We collected formalin-fixed paraffin-embedded tumor blocks and genotyped 32 variants in 15 genes involved in tamoxifen metabolism or transport. We estimated conventional associations for each variant and used prior information about the tamoxifen metabolic path to evaluate the importance of metabolic and transporter pathways. RESULTS No individual variant was notably associated with risk of recurrence in either study population. Both studies showed weak evidence of the importance of phase I metabolism in the clinical response to adjuvant tamoxifen therapy. CONCLUSIONS Consistent with prior knowledge, our results support the role of phase I metabolic capacity in clinical response to tamoxifen. Nonetheless, no individual variant substantially explained the modest phase I effect on tamoxifen response. IMPACT These results are consistent with guidelines recommending against genotype-guided prescribing of tamoxifen, and for the first time provide evidence supporting these guidelines in premenopausal women.

Abstract
During neural tube closure and spinal cord development, many cells die in both the central and peripheral nervous systems (CNS and PNS, respectively). However, myeloid-derived professional phagocytes have not yet colonized the trunk region during early neurogenesis. How apoptotic cells are removed from this region during these stages remains largely unknown. Using live imaging in zebrafish, we demonstrate that neural crest cells (NCCs) respond rapidly to dying cells and phagocytose cellular debris around the neural tube. Additionally, NCCs have the ability to enter the CNS through motor exit point transition zones and clear debris in the spinal cord. Surprisingly, NCCs phagocytosis mechanistically resembles macrophage phagocytosis and their recruitment toward cellular debris is mediated by interleukin-1β. Taken together, our results reveal a role for NCCs in phagocytosis of debris in the developing nervous system before the presence of professional phagocytes.

Abstract
The number of patients with cochlear implants (CIs) is increasing due to expanding indications, and improving CI services. Furthermore, as the use of imaging increases in clinical medicine, it is increasingly likely that patients with CIs will require a magnetic resonance imaging (MRI) examination during their lifetime. Therefore it is important that clinicians are aware of the safety aspects and manufacturer recommendations for CI patients with retained magnets. This article summarises guidelines from all major CI manufacturers and reviews the published literature on the safety of MRI in CI patients with magnets in situ. The most commonly reported complication of MRI in CI patients was pain. Other significant complications included magnet displacement, depolarisation, and polarity reversal. Artefacts caused by the CI remain an issue, but may be reduced by the use of specific sequences. Manufacturer recommendations should be followed to reduce the risk of complications, although complications may occur even when guidelines are followed. For this reason, the indication for imaging these patients should be reviewed, and patients should be appropriately counselled and consented.

Abstract
More and more people are living with the consequences of cancer and its treatment (living with and beyond cancer), yet the level of relevant research is low compared to other types of cancer research in the UK. NCRI aims to increase the level of research in this area and to ultimately improve the lives of those affected by cancer. Undefined research priorities in this broad area has been a barrier to research. The 2015 NHS Independent Cancer Taskforce report also recommends defining research priorities and to enable this research to happen. To address this barrier the NCRI has undertaken a James Lind Alliance Priority Setting Partnership (PSP) to identify priorities that matter most to people affected by cancer and the health and social care professionals.A PSP consists of patients and carers, health and social care professionals. PSPs have several stages and begin with a UK-wide survey to gather questions about uncertainties in living with and beyond cancer. Once the results were analysed, an interim exercise takes place to further prioritise the uncertainties. The last stage is a final workshop where partners debate and finally arrive at a top 10 list of shared uncertainties.The living with and beyond cancer PSP received 3500 questions submitted by people affected by cancer and healthcare professionals. Through a 18-month established rigorous process, the questions are prioritised down to the Top 10 living with and beyond cancer priorities for research in June 2018. This is the first time that clear research priorities have been identified in this area. They are the most impactful research questions that will help improve the lives of people affected by cancer. The Top 10 uncertainties will be publicised widely to ensure that researchers and those who fund research really understand what matters to people affected by cancer. The top uncertainties will be promoted to many research organizations and relevant funders in the UK. We anticipate they will directly influence future research.

Abstract
African swine fever virus causes a haemorrhagic fever in domestic pigs and wild boar. The continuing spread in Africa, Europe and Asia threatens the global pig industry. The lack of a vaccine limits disease control. To underpin rational strategies for vaccine development improved knowledge is needed of how the virus interacts with and modulates the host's responses to infection. The virus long double-stranded DNA genome codes for more than 160 proteins of which many are non-essential for replication in cells but can have important roles in evading the host's defences. Here we review knowledge of the pathways targeted by ASFV and the mechanisms by which these are inhibited. The impact of deleting single or multiple ASFV genes on virus replication in cells and infection in pigs is summarised providing information on strategies for rational development of modified live vaccines.

Abstract
The goal of this study is to present and validate a simple method for accounting for peer selection on offending based on a respondent's self-reported preferences for friends who engage in criminal behavior. Using primary panel data (n = 611), having a preference for peers who offend (the measure of peer selection) relates positively and significantly to offending behavior. The selection measure, which carries the advantage of being closely aligned to criminological theory, renders the peer offending/perso nal offending relationship nonsignificant. Our selection variables also out perform a more traditional means of capturing peer selection effects.

Abstract
NHS Resolution provides indemnity cover for legal claims against the NHS, assists the NHS with risk management and aims to share lessons from claims in order to improve safety. The study aimed to investigate the financial costs of litigation against English Health Trusts in otolaryngology over a 10-year period, to see if any lessons have been learned and identify trends that may lead to a potential reduction in costs and improve patient safety. A Freedom of Information request was made to NHS Resolution for information regarding claims made to otolaryngology departments over the last 10 years. There was a total of 612 successful claims in the 10-year period between 2008/2009 and 2017/2018 with costs of nearly £87 million. Overall, the costs of litigation have increased dramatically, and the main areas for these successful claims can be identified, but restrictions in the detail of information released allows too little insight for improvements to be made to avoid them in future. This continues to be a major problem for healthcare funding and practice.

Abstract
OBJECTIVES Auditory neuropathy spectrum disorder (ANSD) is an audiological diagnosis characterised by hearing dysfunction in the presence of intact outer hair cell function in the cochlea. ANSD is thought to account for 7-10% of all childhood permanent hearing impairment, and can result from a range of pathological processes. This paper describes the rationale, methods and findings from the aetiological investigation of ANSD. METHODS Retrospective audit of four cochlear implant programmes. RESULTS 97 patients were identified. 79% of patients were identified before the age of one. Prematurity and jaundice were the most frequently identified aetiological factors. 33 patients had cochlear nerve deficiency on imaging. Genetic diagnoses identified included otoferlin, SX010 gene, connexin 26 and A1FM1 gene mutations. ANSD was seen in conjunction with syndromes including Kallman syndrome, CHARGE syndrome, X-linked deafness, SOTOS syndrome, Brown Vieletto Van Laere syndrome, and CAPOS syndrome. DISCUSSION We present a two-level system of aetiological investigation that is clinically practical. Patients with ANSD sufficiently severe to consider cochlear implantation are generally identified at an early age. Aetiological investigation is important to guide prognosis and identify comorbidity. CONCLUSION Prematurity and jaundice are the most commonly identified aetiological factors in ANSD. Imaging findings identify crucial factors in a significant minority. An important minority may have genetic and syndromic diagnoses that require further management.

Abstract
Children with fragile X syndrome (FXS) display wide-ranging intellectual and behavioral abilities that affect daily life. We describe the educational setting of students with FXS and assess the relationships between school setting, co-occurring conditions, and functional ability using a national survey sample ( n = 982). The majority of students with FXS in this sample have formal individualized education plans, spend part of the day outside regular classrooms, and receive modifications when in a regular classroom. Males with FXS and certain co-occurring conditions (autism, aggression, and self-injurious behavior) are more likely to spend the entire day outside regular classrooms, compared to males without these co-occurring conditions. Students who spend more time in regular classrooms are more likely to perform functional tasks without help.

Abstract
A key priority of transgender health research is the evaluation of long-term effects of gender affirmation treatment. Thus, accurate assessment of treatment receipt is critical. The data for this analysis came from an electronic medical records (EMR) based cohort of transgender individuals. A subset of cohort members were also asked to complete a self-administered survey. Information from the EMR was compared with survey responses to assess the extent of agreement regarding transmasculine (TM)/transfeminine (TF) status, hormone therapy receipt, and type of surgery performed. Logistic regression models were used to assess whether participant characteristics were associated with disagreement between data sources. Agreement between EMR and survey-derived information was high regarding TM/TF status (99%) and hormone therapy receipt (97%). Lower agreement was observed for chest reconstruction surgery (72%) and genital reconstruction surgery (84%). Using survey responses as the "gold standard", both chest and genital reconstruction surgeries had high specificity (95 and 93%, respectively), but the corresponding sensitivities were low (49 and 68%, respectively). A lower proportion of TM had concordant results for chest reconstruction surgery (64% versus 79% for TF) while genital reconstruction surgery concordance was lower among TF (79% versus 89% for TM). For both surgery types, agreement was highest among the youngest participants. Our findings offer assurance that EMR-based data appropriately classify cohort participants with respect to their TM/TF status or hormone therapy receipt. However, current EMR data may not capture the complete history of gender affirmation surgeries. This information is useful in future studies of outcomes related to gender affirming therapy.

Abstract
BACKGROUND Venous thromboembolism (VTE), ischemic stroke, and myocardial infarction in transgender persons may be related to hormone use. OBJECTIVE To examine the incidence of these events in a cohort of transgender persons. DESIGN Electronic medical record-based cohort study of transgender members of integrated health care systems who had an index date (first evidence of transgender status) from 2006 through 2014. Ten male and 10 female cisgender enrollees were matched to each transgender participant by year of birth, race/ethnicity, study site, and index date enrollment. SETTING Kaiser Permanente in Georgia and northern and southern California. PATIENTS 2842 transfeminine and 2118 transmasculine members with a mean follow-up of 4.0 and 3.6 years, respectively, matched to 48 686 cisgender men and 48 775 cisgender women. MEASUREMENTS VTE, ischemic stroke, and myocardial infarction events ascertained from diagnostic codes through the end of 2016 in transgender and reference cohorts. RESULTS Transfeminine participants had a higher incidence of VTE, with 2- and 8-year risk differences of 4.1 (95% CI, 1.6 to 6.7) and 16.7 (CI, 6.4 to 27.5) per 1000 persons relative to cisgender men and 3.4 (CI, 1.1 to 5.6) and 13.7 (CI, 4.1 to 22.7) relative to cisgender women. The overall analyses for ischemic stroke and myocardial infarction demonstrated similar incidence across groups. More pronounced differences for VTE and ischemic stroke were observed among transfeminine participants who initiated hormone therapy during follow-up. The evidence was insufficient to allow conclusions regarding risk among transmasculine participants. LIMITATION Inability to determine which transgender members received hormones elsewhere. CONCLUSION The patterns of increases in VTE and ischemic stroke rates among transfeminine persons are not consistent with those observed in cisgender women. These results may indicate the need for long-term vigilance in identifying vascular side effects of cross-sex estrogen.

Abstract
BACKGROUND Understanding the magnitude of mental health problems, particularly life-threatening ones, experienced by transgender and/or gender nonconforming (TGNC) youth can lead to improved management of these conditions. METHODS Electronic medical records were used to identify a cohort of 588 transfeminine and 745 transmasculine children (3-9 years old) and adolescents (10-17 years old) enrolled in integrated health care systems in California and Georgia. Ten male and 10 female referent cisgender enrollees were matched to each TGNC individual on year of birth, race and/or ethnicity, study site, and membership year of the index date (first evidence of gender nonconforming status). Prevalence ratios were calculated by dividing the proportion of TGNC individuals with a specific mental health diagnosis or diagnostic category by the corresponding proportion in each reference group by transfeminine and/or transmasculine status, age group, and time period before the index date. RESULTS Common diagnoses for children and adolescents were attention deficit disorders (transfeminine 15%; transmasculine 16%) and depressive disorders (transfeminine 49%; transmasculine 62%), respectively. For all diagnostic categories, prevalence was severalfold higher among TGNC youth than in matched reference groups. Prevalence ratios (95% confidence intervals [CIs]) for history of self-inflicted injury in adolescents 6 months before the index date ranged from 18 (95% CI 4.4-82) to 144 (95% CI 36-1248). The corresponding range for suicidal ideation was 25 (95% CI 14-45) to 54 (95% CI 18-218). CONCLUSIONS TGNC youth may present with mental health conditions requiring immediate evaluation and implementation of clinical, social, and educational gender identity support measures.

Abstract
BACKGROUND Transgender people and persons with disorders of sex development (DSD) are two separate categories of gender minorities, each characterized by unique cancer risk factors. Although cancer registry data typically include only two categories of sex, registrars have the option of indicating that a patient is transgender or has a DSD. METHODS Data for primary cancer cases in 46 states and the District of Columbia were obtained from the North American Association of Central Cancer Registries (NAACCR) database for the period 1995-2013. The distributions of primary sites and categories of cancers with shared risk factors were examined separately for transgender and DSD patients and compared to the corresponding distributions in male and female cancer patients. Proportional incidence ratios were calculated by dividing the number of observed cases by the number of expected cases. Expected cases were calculated based on the age- and year of diagnosis-specific proportions of cases in each cancer category observed among male and female patients. RESULTS Transgender patients have significantly elevated proportional incidence ratios (95% confidence intervals) for viral infection induced cancers compared to either males (2.3; 2.0-2.7) or females (3.3; 2.8-3.7). Adult DSD cancer patients have a similar distribution of primary sites compared to male or female patients but DSD children with cancer have ten times more cases of testicular malignancies than expected (95% confidence interval: 4.7-20). CONCLUSION The proportions of certain primary sites and categories of malignancies among transgender and DSD cancer patients are different from the proportions observed for male or female patients.

Abstract
BACKGROUND Transgender individuals sometimes seek gender confirmation treatments (GCT), including hormone therapy (HT) and/or surgical change of the chest and genitalia ("top" and "bottom" gender confirmation surgeries). These treatments may ameliorate distress resulting from the incongruence between one's physical appearance and gender identity. AIM The aim was to examine the degree to which individuals' body-gender congruence, body image satisfaction, depression, and anxiety differed by GCT groups in cohorts of transmasculine (TM) and transfeminine (TF) individuals. METHODS The Study of Transition, Outcomes, and Gender is a cohort study of transgender individuals recruited from 3 health plans located in Georgia, Northern California, and Southern California; cohort members were recruited to complete a survey between 2015-2017. Participants were asked about: history of GCT; body-gender congruence; body image satisfaction; depression; and anxiety. Participants were categorized as having received: (1) no GCT to date; (2) HT only; (3) top surgery; (4) partial bottom surgery; and (5) definitive bottom surgery. OUTCOMES Outcomes of interest included body-gender congruence, body image satisfaction, depression, and anxiety. RESULTS Of the 2,136 individuals invited to participate, 697 subjects (33%) completed the survey, including 347 TM and 350 TF individuals. The proportion of participants with low body-gender congruence scores was significantly higher in the "no treatment" group (prevalence ratio [PR] = 3.96, 95% CI 2.72-5.75) compared to the definitive bottom surgery group. The PR for depression comparing participants who reported no treatment relative to those who had definitive surgery was 1.94 (95% CI 1.42-2.66); the corresponding PR for anxiety was 4.33 (95% CI 1.83-10.54). CLINICAL TRANSLATION Withholding or delaying GCT until depression or anxiety have been treated may not be the optimal treatment course given the benefits of reduced levels of distress after undergoing these interventions. CONCLUSIONS Strengths include the well-defined sampling frame, which allowed correcting for non-response, a sample with approximately equal numbers of TF and TM participants, and the ability to combine data on HT and gender confirmation surgeries. Limitations include the cross-sectional design and the fact that participants may not be representative of the transgender population in the United States. Body-gender congruence and body image satisfaction were higher, and depression and anxiety were lower among individuals who had more extensive GCT compared to those who received less treatment or no treatment at all.

Abstract
PURPOSE The Study of Transition, Outcomes and Gender (STRONG) was initiated to assess the health status of transgender people in general and following gender-affirming treatments at Kaiser Permanente health plans in Georgia, Northern California and Southern California. The objectives of this communication are to describe methods of cohort ascertainment and data collection and to characterise the study population. PARTICIPANTS A stepwise methodology involving computerised searches of electronic medical records and free-text validation of eligibility and gender identity was used to identify a cohort of 6456 members with first evidence of transgender status (index date) between 2006 and 2014. The cohort included 3475 (54%) transfeminine (TF), 2892 (45%) transmasculine (TM) and 89 (1%) members whose natal sex and gender identity remained undetermined from the records. The cohort was matched to 127 608 enrollees with no transgender evidence (63 825 women and 63 783 men) on year of birth, race/ethnicity, study site and membership year of the index date. Cohort follow-up extends through the end of 2016. FINDINGS TO DATE About 58% of TF and 52% of TM cohort members received hormonal therapy at Kaiser Permanente. Chest surgery was more common among TM participants (12% vs 0.3%). The proportions of transgender participants who underwent genital reconstruction surgeries were similar (4%-5%) in the two transgender groups. Results indicate that there are sufficient numbers of events in the TF and TM cohorts to further examine mental health status, cardiovascular events, diabetes, HIV and most common cancers. FUTURE PLANS STRONG is well positioned to fill existing knowledge gaps through comparisons of transgender and reference populations and through analyses of health status before and after gender affirmation treatment. Analyses will include incidence of cardiovascular disease, mental health, HIV and diabetes, as well as changes in laboratory-based endpoints (eg, polycythemia and bone density), overall and in relation to gender affirmation therapy.

Abstract
Importance The use of contralateral prophylactic mastectomies (CPMs) among patients with invasive unilateral breast cancer has increased substantially during the past decade in the United States despite the lack of evidence for survival benefit. However, whether this trend varies by state or whether it is correlated with changes in proportions of reconstructive surgery among these patients is unclear. Objective To determine state variation in the temporal trend and in the proportion of CPMs among women with early-stage unilateral breast cancer treated with surgery. Design, Setting, and Participants A retrospective cohort study of 1.2 million women 20 years of age or older diagnosed with invasive unilateral early-stage breast cancer and treated with surgery from January 1, 2004, through December 31, 2012, in 45 states and the District of Columbia as compiled by the North American Association of Central Cancer Registries. Data analysis was performed from August 1, 2015, to August 31, 2016. Exposure Contralateral prophylactic mastectomy. Main Outcomes and Measures Temporal changes in the proportion of CPMs among women with early-stage unilateral breast cancer treated with surgery by age and state, overall and in relation to changes in the proportions of those who underwent reconstructive surgery. Results Among the 1 224 947 women with early-stage breast cancer treated with surgery, the proportion who underwent a CPM nationally increased between 2004 and 2012 from 3.6% (4013 of 113 001) to 10.4% (12 890 of 124 231) for those 45 years or older and from 10.5% (1879 of 17 862) to 33.3% (5237 of 15 745) for those aged 20 to 44 years. The increase was evident in all states, although the magnitude of the increase varied substantially across states. For example, among women 20 to 44 years of age, the proportion who underwent a CPM from 2004-2006 to 2010-2012 increased from 14.9% (317 of 2121) to 24.8% (436 of 1755) (prevalence ratio [PR], 1.66; 95% CI, 1.46-1.89) in New Jersey compared with an increase from 9.8% (162 of 1657) to 32.2% (495 of 1538) (PR, 3.29; 95% CI, 2.80-3.88) in Virginia. In this age group, CPM proportions for the period from 2010 to 2012 were over 42% in the contiguous states of Nebraska, Missouri, Colorado, Iowa, and South Dakota. From 2004 to 2012, the proportion of reconstructive surgical procedures among women aged 20 to 44 years who were diagnosed with early-stage breast cancer and received a CPM increased in many states; however, it did not correlate with the proportion of women who received a CPM. Conclusions and Relevance The increase in the proportion of CPMs among women with early-stage unilateral breast cancer treated with surgery varied substantially across states. Notably, in 5 contiguous Midwest states, nearly half of young women with invasive early-stage breast cancer underwent a CPM from 2010 to 2012. Future studies should examine the reasons for the geographic variation and increasing trend in the use of CPMs.

Abstract
Waste water treatment plants (WWTPs) are receptors for the cumulative loading of microplastics (MPs) derived from industry, landfill, domestic wastewater and stormwater. The partitioning of MPs through the settlement processes of wastewater treatment results in the majority becoming entrained in the sewage sludge. This study characterized MPs in sludge samples from seven WWTPs in Ireland which use anaerobic digestion (AD), thermal drying (TD), or lime stabilization (LS) treatment processes. Abundances ranged from 4196 to 15 385 particles kg-1 (dry weight). Results of a general linear mixed model (GLMM) showed significantly higher abundances of MPs in smaller size classes in the LS samples, suggesting that the treatment process of LS shears MP particles. In contrast, lower abundances of MPs found in the AD samples suggests that this process may reduce MP abundances. Surface morphologies examined using scanning electron microscopy (SEM) showed characteristics of melting and blistering of TD MPs and shredding and flaking of LS MPs. This study highlights the potential for sewage sludge treatment processes to affect the risk of MP pollution prior to land spreading and may have implications for legislation governing the application of biosolids to agricultural land.

Abstract
Transgender people comprise a diverse group of individuals whose gender identity or expression differs from that originally assigned to them at birth. Some, but not all, transgender people elect to undergo medical gender affirmation, which may include therapy with cross-sex hormones and/or surgical change of the genitalia and other sex characteristics. As cross-sex hormones administered for the purposes of gender affirmation may be delivered at high doses and over a period of decades, the carcinogenicity of hormonal therapy in transgender people is an area of considerable concern. In addition, concerns about cancer risk in transgender patients have been linked to sexually transmitted infections, increased exposure to well-known risk factors such as smoking and alcohol use, and the lack of adequate access to screening. Several publications have identified cancer as an important priority in transgender health research and called for large-scale studies. The goals of this article are to summarize the evidence on factors that may differentially affect cancer risk in transgender people, assess the relevant cancer surveillance and epidemiologic data available to date, and offer an overview of possible methodological considerations for future studies investigating cancer incidence and mortality in this population.

Abstract
Encounters with jugular bulb abnormalities during ear surgery are a rare but recognised problem. A high riding jugular bulb is present in 10%-15% of patients and its variable position within the temporal bone can lead to problems as brisk venous haemorrhage can result if the bulb is inadvertently opened. The case of a 52-year-old woman with a central tympanic membrane perforation who underwent elective endaural myringoplasty and experienced brisk bleeding on raising the tympanomeatal flap is presented.

Abstract
Frustrations attending East/West feminist dialogs in the early days of post-socialism were particularly visible in the Czech Republic. English-language publications explained why Czechs were not going to accept feminism easily, despite the growth of new gender studies centers. This article explores the works of three scholars who participated in these discussions: sociologist Marie Čermáková, philosopher and sociologist Hana Havelková, and sociologist Jiřina Šiklová. It argues that in the early to mid-1990s, Czech gender scholars' explanations of why feminism was inappropriate in the Czech context reproduced state narratives of family and gender relations from the interwar and socialist era. Feminist writings from Western Europe and the US often make explicit the contrast between state agendas and women's lives. Czech narratives of past experiences with the state, however, served as a framework for navigating the early post-socialist era.

Abstract
Alexine, a naturally occurring pyrrolizidine alkaloid, isolated from Alexa leiopetala, and four stereoisomers, isolated from Castanospermum australe, were investigated for inhibitory activity against the growth of HIV-1. Only treatment with the 7,7a-diepialexine restricted virus growth (IC50 0.38 mm) although it was less active than the indolizidine alkaloid castanospermine (IC50 0.02 mm). The antiviral effects of 7,7a-diepialexine, like castanospermine, correlated with the inhibitory activity against purified pig kidney α-glucosidase 1 of the glycoprotein processing enzymes and the reduced cleavage of the precursor HIV-1 glycoprotein gp160.
