Abstract
Background Differentiating among cardiac diseases associated with left ventricular hypertrophy (LVH) informs diagnosis and clinical care. Objective To evaluate if artificial intelligence-enabled analysis of the 12-lead electrocardiogram (ECG) facilitates automated detection and classification of LVH. Methods We used a pretrained convolutional neural network to derive numerical representations of 12-lead ECG waveforms from patients in a multi-institutional healthcare system who had cardiac diseases associated with LVH (n = 50,709), including cardiac amyloidosis (n = 304), hypertrophic cardiomyopathy (n = 1056), hypertension (n = 20,802), aortic stenosis (n = 446), and other causes (n = 4766). We then regressed LVH etiologies relative to no LVH on age, sex, and the numerical 12-lead representations using logistic regression ("LVH-Net"). To assess deep learning model performance on single-lead data analogous to mobile ECGs, we also developed 2 single-lead deep learning models by training models on lead I ("LVH-Net Lead I") or lead II ("LVH-Net Lead II") from the 12-lead ECG. We compared the performance of the LVH-Net models to alternative models fit on (1) age, sex, and standard ECG measures, and (2) clinical ECG-based rules for diagnosing LVH. Results The areas under the receiver operator characteristic curve of LVH-Net by specific LVH etiology were cardiac amyloidosis 0.95 [95% CI, 0.93-0.97], hypertrophic cardiomyopathy 0.92 [95% CI, 0.90-0.94], aortic stenosis LVH 0.90 [95% CI, 0.88-0.92], hypertensive LVH 0.76 [95% CI, 0.76-0.77], and other LVH 0.69 [95% CI 0.68-0.71]. The single-lead models also discriminated LVH etiologies well. Conclusion An artificial intelligence-enabled ECG model is favorable for detection and classification of LVH and outperforms clinical ECG-based rules.

Abstract
Based on the inclusive and methodologically rigorous framework provided by Ed Zigler's developmental approach, we previously challenged what we called, 'the mysterious myth of attention deficit', the fallacy of attention as a universal deficit among persons with intellectual disability (ID). In this latest update, we conducted a systematic review of studies of essential components of attention among persons with ID published in the interim since the last iteration of the mysterious myth narrative was submitted for publication approximately a decade ago. We searched the databases PubMed and PsycINFO for English-language peer-reviewed studies published from 1 January 2011 through 5 February 2021. In keeping with the developmental approach, the two essential methodological criteria were that the groups of persons with ID were aetiologically homogeneous and that the comparisons with persons with average IQs (or with available norms) were based on an appropriate index of developmental level, or mental age. Stringent use of these criteria for inclusion served to control for bias in article selection. Articles were then categorised based on aetiological group studied and component of visual attention. Based on these criteria, 18 articles were selected for inclusion out of the 2837 that were identified. The included studies involved 547 participants: 201 participants with Down syndrome, 214 participants with Williams syndrome and 132 participants with fragile X syndrome. The findings from these articles call attention to the complexities and nuances in understanding attentional functioning across homogeneous aetiological groups and highlight that functioning must be considered in relation to aetiology; factors associated with the individual, such as developmental level, motivation, styles and biases; and factors associated with both the task, such as context, focus, social and emotional implications, and levels of environmental complexity.

Abstract
Abstract
On the basis of the EGOS 2021 sub-plenary on ‘Professions and Inequality: Challenges, Controversies, and Opportunities’, the presenters and panellists wrote four short essays on the relationship between inequality as a grand challenge and professional occupations and organizations, their structures, practices, and strategies. Individually, these essays take an inquisitorial stance on extant understandings of (1) how professions may exacerbate existing inequalities and (2) how professions can be part of the solution and help tackle inequality as a grand challenge. Taken together, the discussion forum aims at advancing scholarly debates on inequality by showing how professions’ scholarship may critically interrogate extant understandings of inequality as a broad, multifaceted concept, whilst providing fruitful directions for research on inequality, their potential solutions, and the role and responsibilities of organization and management scholars.

Abstract
BACKGROUND The randomized, double-blind OlympiA trial compared 1 year of the oral poly(adenosine diphosphate-ribose) polymerase inhibitor, olaparib, to matching placebo as adjuvant therapy for patients with pathogenic or likely pathogenic variants in germline BRCA1 or BRCA2 (gBRCA1/2pv) and high-risk, human epidermal growth factor receptor 2-negative, early breast cancer (EBC). The first pre-specified interim analysis (IA) previously demonstrated statistically significant improvement in invasive disease-free survival (IDFS) and distant disease-free survival (DDFS). The olaparib group had fewer deaths than the placebo group, but the difference did not reach statistical significance for overall survival (OS). We now report the pre-specified second IA of OS with updates of IDFS, DDFS, and safety. PATIENTS AND METHODS One thousand eight hundred and thirty-six patients were randomly assigned to olaparib or placebo following (neo)adjuvant chemotherapy, surgery, and radiation therapy if indicated. Endocrine therapy was given concurrently with study medication for hormone receptor-positive cancers. Statistical significance for OS at this IA required P < 0.015. RESULTS With a median follow-up of 3.5 years, the second IA of OS demonstrated significant improvement in the olaparib group relative to the placebo group [hazard ratio 0.68; 98.5% confidence interval (CI) 0.47-0.97; P = 0.009]. Four-year OS was 89.8% in the olaparib group and 86.4% in the placebo group (Δ 3.4%, 95% CI -0.1% to 6.8%). Four-year IDFS for the olaparib group versus placebo group was 82.7% versus 75.4% (Δ 7.3%, 95% CI 3.0% to 11.5%) and 4-year DDFS was 86.5% versus 79.1% (Δ 7.4%, 95% CI 3.6% to 11.3%), respectively. Subset analyses for OS, IDFS, and DDFS demonstrated benefit across major subgroups. No new safety signals were identified including no new cases of acute myeloid leukemia or myelodysplastic syndrome. CONCLUSION With 3.5 years of median follow-up, OlympiA demonstrates statistically significant improvement in OS with adjuvant olaparib compared with placebo for gBRCA1/2pv-associated EBC and maintained improvements in the previously reported, statistically significant endpoints of IDFS and DDFS with no new safety signals.

Abstract
Loss-of-function mutations in genes encoding the Krebs cycle enzymes Fumarate Hydratase (FH) and Succinate Dehydrogenase (SDH) induce accumulation of fumarate and succinate, respectively and predispose patients to hereditary cancer syndromes including the development of aggressive renal cell carcinoma (RCC). Fumarate and succinate competitively inhibit αKG-dependent dioxygenases, including Lysine-specific demethylase 4A/B (KDM4A/B), leading to suppression of the homologous recombination (HR) DNA repair pathway. In this study, we have developed new syngeneic Fh1- and Sdhb-deficient murine models of RCC, which demonstrate the expected accumulation of fumarate and succinate, alterations in the transcriptomic and methylation profile, and an increase in unresolved DNA double-strand breaks (DSBs). The efficacy of poly ADP-ribose polymerase inhibitors (PARPis) and temozolomide (TMZ), alone and in combination, was evaluated both in vitro and in vivo. Combination treatment with PARPi and TMZ results in marked in vitro cytotoxicity in Fh1- and Sdhb-deficient cells. In vivo, treatment with standard dosing of the PARP inhibitor BGB-290 and low-dose TMZ significantly inhibits tumor growth without a significant increase in toxicity. These findings provide the basis for a novel therapeutic strategy exploiting HR deficiency in FH and SDH-deficient RCC with combined PARP inhibition and low-dose alkylating chemotherapy.

Abstract
BackgroundStrong biologic rationale supports both vitamin D and marine omega-3 (n-3) fatty acids for prevention of autoimmune disease (AD). Within the randomized, double-blind, placebo-controlled VITamin D and OmegA-3 TriaL (VITAL), we tested the effects of these supplements on AD incidence. We previously reported results after 5.3 years of randomized follow-up showing overall protective effects for vitamin D on AD incidence (HR 0.78, 95% CI 0.61-0.99) and suggestive results for n-3 fatty acids (HR 0.85, 95%CI 0.67-1.08)1.ObjectivesWe aimed to test effects of these supplements with two more years of post-intervention follow-up in VITAL.MethodsVITAL enrolled and randomized men and women (age ≥50 and ≥55 years, respectively) in a 2-by-2 factorial design to vitamin D3 (2000 IU/d) and/or n-3 fatty acids (1000 mg/d) or placebo and followed for median 5.3 years. Here, we followed participants for another 2 years of observation to assess for sustained effects. Incident AD diagnoses were reported by participants annually and confirmed by medical record review by expert physicians using existing classification criteria. The primary endpoint was total incident AD, including rheumatoid arthritis (RA), polymyalgia rheumatica (PMR), autoimmune thyroid disease (AITD), psoriasis, and all others. Pre-specified secondary endpoints included individual common AD; and probable AD. Cox models calcuated hazard ratios (HR) for incident ADs.ResultsOf 25,871 participants randomized, 71% self-reported non-Hispanic Whites, 20% Black, 9% other racial/ethnic groups, 51% women, mean age was 67.1 years. During 7.5 years median follow-up, confirmed AD was diagnosed in 156 participants in vitamin D arm vs 198 in vitamin D placebo arm, HR 0.79 (0.64-0.97). Incident AD was confirmed in 167 participants in n-3 fatty acid arm and 187 in n-3 fatty acid placebo arm, HR 0.89 (0.72-1.10). For vitamin D, HRs trended toward reduction for RA 0.67 (0.37- 1.21), PMR 0.69 (0.46-1.03) and psoriasis 0.57 (0.33-0.99). For n-3 fatty acids, HRs trended toward reduction for RA 0.55 (0.30-1.10) and AITD 0.61 (0.33-1.12). Vitamin D’s effect on AD incidence was stronger in those with body mass index (BMI) < 25 (HR 0.65, 0.44-0.96) than ≥ 25 kg/m2 (p interaction 0.01).ConclusionSupplementation for 5.3 years with 2000 IU/day vitamin D (compared to placebo), followed by 2 years of observational follow-up, significantly reduced overall incident AD by 21% in older adults. HRs for RA, PMR and psoriasis trended toward reduction with vitamin D, with stronger effect in those with normal BMI. Supplementation with 1000 mg/day n-3 fatty acids did not significantly reduce total AD.References[1]Hahn J et al, BMJ, 2022 Jan 26;376: e066452.Table 1.Hazard Ratios for Primary and Secondary Endpoints, by Randomized Assignment to Vitamin D/Placebo (Left), N-3 Fatty Acids/Placebo (Right)aEndpointVitamin D3(N=12,927)Placebo (N=12,944)Hazard Ratio (95% CI)pN-3 Fatty Acids (N=12,933)Placebo (N=12,938)Hazard Ratio (95% CI)pPrimary: Confirmed AD1561980.79 (0.64-0.97)0.031671870.89 (0.72-1.10)0.27Secondary:Confirmed + probable AD2653210.83 (0.70-0.97)0.022713150.86 (0.73-1.01)0.06Excluding subjects with any pre-randomization AD Confirmed AD1271620. 79 (0.62-0.99)0.041411480.95 (0.75-1.20)0.66 Confirmed + probable AD2112700. 78 (0.65-0.94)0.0072322490.93 (0.78-1.11)0.41Excluding first 2 years follow-up Confirmed AD861300.66 (0.50-0.87)0.0031041120.92 (0.71-1.21)0.56 Confirmed + probable AD1472050.72 (0.58-0.89)0.0021721800.95 (0.77-1.17)0.63Individual ADb RA18270.67 (0.37-1.21)0.1816290.55 (0.30-1.01)0.06 PMR39570.69 (0.46-1.03)0.0746500.92 (0.61-1.37)0.67 AITD27181.50 (0.82-2.71)0.1917280.61 (0.33-1.12)0.11 Psoriasis20350.57 (0.33-0.99)0.0534211.62 (0.94-2.79)0.08aAnalyses from Cox regression models controlled for age, sex, race, and other (n-3 fatty acid or vitamin D) randomization group bConfirmed AD.Figure 1.Disclosure of InterestsKaren Costenbader Consultant of: Astra Zeneca, Glaxo Smith Kline, Neutrolis, Grant/research support from: Merck, Exagen, Gilead, Nancy Cook: None declared, I-min Lee: None declared, Jill Hahn: None declared, Joseph Walter: None declared, Vadim Bubes: None declared, Gregory Kotler: None declared, Nicole Yang: None declared, Sonia Friedman: None declared, Erik Alexander: None declared, JoAnn Manson: None declared.

Abstract
Nonalcoholic steatohepatitis (NASH), a chronic liver disease without an approved therapy, is associated with lipotoxicity and insulin resistance and is a major cause of cirrhosis and hepatocellular carcinoma. Aramchol, a partial inhibitor of hepatic stearoyl-CoA desaturase (SCD1) improved steatohepatitis and fibrosis in rodents and reduced steatosis in an early clinical trial. ARREST, a 52-week, double-blind, placebo-controlled, phase 2b trial randomized 247 patients with NASH (n = 101, n = 98 and n = 48 in the Aramchol 400 mg, 600 mg and placebo arms, respectively; NCT02279524 ). The primary end point was a decrease in hepatic triglycerides by magnetic resonance spectroscopy at 52 weeks with a dose of 600 mg of Aramchol. Key secondary end points included liver histology and alanine aminotransferase (ALT). Aramchol 600 mg produced a placebo-corrected decrease in liver triglycerides without meeting the prespecified significance (-3.1, 95% confidence interval (CI) -6.4 to 0.2, P = 0.066), precluding further formal statistical analysis. NASH resolution without worsening fibrosis was achieved in 16.7% (13 out of 78) of Aramchol 600 mg versus 5% (2 out of 40) of the placebo arm (odds ratio (OR) = 4.74, 95% CI = 0.99 to 22.7) and fibrosis improvement by ≥1 stage without worsening NASH in 29.5% versus 17.5% (OR = 1.88, 95% CI = 0.7 to 5.0), respectively. The placebo-corrected decrease in ALT for 600 mg was -29.1 IU l-1 (95% CI = -41.6 to -16.5). Early termination due to adverse events (AEs) was <5%, and Aramchol 600 and 400 mg were safe, well tolerated and without imbalance in serious or severe AEs between arms. Although the primary end point of a reduction in liver fat did not meet the prespecified significance level with Aramchol 600 mg, the observed safety and changes in liver histology and enzymes provide a rationale for SCD1 modulation as a promising therapy for NASH and fibrosis and are being evaluated in an ongoing phase 3 program.

Abstract
Criminal justice involved (CJI) individuals with a history of opioid use disorder (OUD) are at high risk of overdose and death in the weeks following release from jail. We developed the Justice-Community Circulation Model (JCCM) to investigate OUD/CJI dynamics post-release and the effects of interventions on overdose deaths. The JCCM uses a synthetic agent-based model population of approximately 150,000 unique individuals that is generated using demographic information collected from multiple Chicago-area studies and data sets. We use a high-performance computing (HPC) workflow to implement a sequential approximate Bayesian computation algorithm for calibrating the JCCM. The calibration results in the simulated joint posterior distribution of the JCCM input parameters. The calibrated model is used to investigate the effects of a naloxone intervention for a mass jail release. The simulation results show the degree to which a targeted intervention focusing on recently released jail inmates can help reduce the risk of death from opioid overdose.

Abstract
STUDY OBJECTIVE Acute chest syndrome is a leading cause of mortality in patients with sickle cell disease (SCD). Because early detection of acute chest syndrome is directly tied to prognosis, young patients with SCD undergo countless chest radiography screenings throughout their lifetime for commonly occurring acute chest syndrome risk factors such as fever, chest pain, or cough. Chest radiography is not an ideal screening method because it is associated with radiation exposure, which accumulates with repeated imaging. Point-of-care lung ultrasonography is a nonradiating imaging modality that has been used to identify other lung pathology and may have a role in SCD. The goal of this study was to determine the accuracy of point-of-care lung ultrasound to identify an infiltrate suggestive of acute chest syndrome in patients with SCD compared to chest radiography as the gold standard. METHODS This was a prospective observational study in 2 urban pediatric emergency departments to evaluate the accuracy of point-of-care lung ultrasonography in identifying patients with SCD who were aged 0 to 21 years and had an infiltrate suggestive of acute chest syndrome compared with chest radiography. Clinicians and trainees with point-of-care lung ultrasonographic training obtained informed consent and performed investigational point-of-care lung ultrasonography to evaluate for lung consolidation. A blinded point-of-care lung ultrasonographic expert reviewed results for quality assurance and agreement. Accuracy, sensitivity, specificity, likelihood ratios, and positive and negative predictive value were calculated for point-of-care lung ultrasonography test performance characteristics, with chest radiography as a reference standard. RESULTS Point-of-care lung ultrasonography was performed on 191 SCD patients with a mean age of 8 years; 41% were female patients, and there was a 17% prevalence of acute chest syndrome. Accuracy of point-of-care lung ultrasonography to detected acute chest syndrome was 92%, sensitivity was 88%, and specificity was 93% compared with that for chest radiography. CONCLUSION Point-of-care lung ultrasonography is a feasible alternative to chest radiography for screening for acute chest syndrome in young patients with SCD. Further studies are needed to determine how this test performs within clinical practice.

Abstract
BACKGROUND Much remains unknown in rural risk environments, despite a growing crisis in these areas. We adapt a risk environment framework to characterize rural southern Illinois and describe the relations of risk environments, opioid-related overdose, HIV, Hepatitis C, and sexually transmitted infection rates between 2015 and 2017. METHODS Over two dozen risk environment variables are summarized across zip-code (n = 128) or county levels (n = 16) based on availability and theoretical relevance. We calculate data attribute associations and characterize spatial and temporal dimensions of longitudinal health outcomes and the rural risk environment. We then use a "regional typology analysis" to generate data-driven risk regions and compare health outcomes. RESULTS Pervasive risk hotspots were identified in more populated locales with higher rates of overdose and HCV incidence, whereas emerging risk areas were isolated to more rural locales that had experienced an increase in analgesic opiate overdoses and generally lacked harm-reduction resources. At-risk areas were characterized with underlying socioeconomic vulnerability but in differing ways, reflecting a nuanced and shifting structural risk landscape. CONCLUSIONS Rural risk environment vulnerabilities and associated opioid-related health outcomes are multifaceted and spatially heterogeneous. More research is needed to better understand how refining geographies to more precisely define risk can support intervention efforts and further enrich investigations of the opioid epidemic.

Abstract
Abstract
Objective
To examine differences at baseline between children with ADHD and/or LD vs. children with neither ADHD/LD on 1) neurocognitive scores and 2) child- and parent-reported concussion symptoms.
Method
Retrospective data was obtained for 1856 children ages 5–11 who were assessed at baseline using ImPACT Pediatric. Groups were determined based on parent-reported diagnosis of their child at baseline (ADHD and/or LD vs. neither ADHD/LD), and groups were compared on the four factor scores: Sequential Memory, Word Memory, Visual Memory, and Rapid Processing and on child- and parent-reported concussion symptoms using a series of ANOVAs.
Results
ANOVAs revealed that children with ADHD and/or LD performed significantly worse than children without ADHD/LD on Sequential Memory (F(1,1845) = 69.86, p < .001)) and Word Memory (F(1,1853) = 10.36, p = .001)). In contrast, children with ADHD and/or LD performed significantly better on the neurocognitive measures of Visual Memory [(F(1,1845) = 4.94, p = .026)] and Rapid Processing [(F(1,1853) = 20.35, p < .001). Symptom reporting was significantly greater in the ADHD and/or LD group for both child (F(1,1853) = 30.21, p < .001) and parent (F(1,1853) = 34.64, p < .001) reported symptoms.
Conclusions
The current study demonstrated differences at baseline in children on neurocognitive performance and concussion symptom reporting based on diagnostic group. Analysis of symptom reporting suggested that children with pre-existing diagnoses of ADHD and/or LD and their parents may report concussion-like symptoms at baseline, prior to ever experiencing a concussion. This finding has clinical implications for interpretation of post-concussion symptoms without a baseline comparison in children with pre-existing diagnoses such as ADHD and/or LD.

Abstract
In this paper we explore for the first time regional differences in the patterning of occupational social mobility in the UK. Drawing on data from Understanding Society (US), supported by the Labour Force Survey (LFS), we examine how rates of absolute and relative intergenerational occupational mobility vary across 19 regions of England, Scotland and Wales. Our findings somewhat problematise the dominant policy narrative on regional social mobility, which presents London as the national ‘engine-room’ of social mobility. In contrast, we find that those currently living in Inner London have experienced the lowest regional rate of absolute upward mobility, the highest regional rate of downward mobility, and a comparatively low rate of relative upward mobility into professional and managerial occupations. This stands in stark contrast to Merseyside and particularly Tyne and Wear where rates of both absolute and relative upward mobility are high, and downward mobility is low. We then examine this Inner London effect further, finding that it is driven in part by two dimensions of migration. First, among international migrants, we find strikingly low rates of upward mobility and high rates of downward mobility. Second, among domestic migrants, we find a striking overrepresentation of those from professional and managerial backgrounds. These privileged domestic migrants, our results indicate, are less likely to experience downward mobility than those from similar backgrounds elsewhere in the country. This may be partly explained by higher educational qualifications, but may also be indicative of a glass floor or opportunity hoarding.

Abstract
Abstract
Summary
We investigate convolutional neural networks (CNNs) for filtering small genomic variants in short-read DNA sequence data. Errors created during sequencing and library preparation make variant calling a difficult task. Encoding the reference genome and aligned reads covering sites of genetic variation as numeric tensors allows us to leverage CNNs for variant filtration. Convolutions over these tensors learn to detect motifs useful for classifying variants. Variant filtering models are trained to classify variants as artifacts or real variation. Visualizing the learned weights of the CNN confirmed it detects familiar DNA motifs known to correlate with real variation, like homopolymers and short tandem repeats (STR). After confirmation of the biological plausibility of the learned features we compared our model to current state-of-the-art filtration methods like Gaussian Mixture Models, Random Forests and CNNs designed for image classification, like DeepVariant. We demonstrate improvements in both sensitivity and precision. The tensor encoding was carefully tailored for processing genomic data, respecting the qualitative differences in structure between DNA and natural images. Ablation tests quantitatively measured the benefits of our tensor encoding strategy. Bayesian hyper-parameter optimization confirmed our notion that architectures designed with DNA data in mind outperform off-the-shelf image classification models. Our cross-generalization analysis identified idiosyncrasies in truth resources pointing to the need for new methods to construct genomic truth data. Our results show that models trained on heterogenous data types and diverse truth resources generalize well to new datasets, negating the need to train separate models for each data type.

Abstract
Materials used to seal the endodontic space are subjected to enzymatic degradative activities of body fluids and bacteria. OBJECTIVES To assess effects of simulated human salivary, blood and bacterial esterases (SHSE) on physical properties of typical restorative material and root canal sealers. METHODS Specimens of set methacrylate-based resin composite (BisfilTM2B; RC), calcium-silicate sealer (EndoSequence®; BC) or epoxy-resin sealer (AH-Plus®; ER) were tested after up to 28Days exposure to phosphate buffered saline (PBS) or SHSE, using ANSI/ADA-57:2000 and ISO-6876:2012. RESULTS Regardless of media, microhardness increased with time for BC remained unchanged for ER and decreased for RC (p < 0.05). SHSE moderated the increase for BC compared to PBS (28.0 ± 4.8 vs. 38.1 ± 7.9 KHN) at 7Days, and enhanced the decrease for RC at 7Days (55.6 ± 7.1 vs. 66.3 ± 6.5 KHN) and 28Days (52.3 ± 9.2 vs. 62.6 ± 8.5 KHN). Compressive strength was enhanced only for BC by either media. BC expanded with time for both incubation conditions; SHSE moderated the expansion compared to PBS at 7Days (0.026 ± 0.01% vs. 0.049 ± 0.007%). Shrinkage of ER was similar for both incubation media and was lower than that for RC (p < 0.05). Shrinkage of RC was enhanced by SHSE compared to PBS at 7Days (0.5 ± 0.07% vs. 0.38 ± 0.08%). Weight loss was lowest for ER and highest for BC (p < 0.05). It was enhanced by SHSE compared to PBS for BC at 28Days (2.40 ± 0.2 vs. 2.96 ± 0.19 W L%), and for RC at 7Days (0.54 ± 0.09 vs. 0.80 ± 0.1 W L%). SIGNIFICANCE Simulated body fluids and bacterial esterases affected the physical properties of test materials, suggesting potential impacts on sealing ability and resistance to bacterial ingress, and tooth strength ultimately affecting their clinical performance.

Abstract
BACKGROUND Men with inflammatory bowel disease (IBD) may have decreased sexual function due to factors related to the underlying disease, medication, and/or surgery. We aimed to examine the use of erectile dysfunction (ED) medications in men with IBD. METHODS This is a nationwide cohort study based on the Danish registries, comprising all men >18 years old with IBD during 1 January 1995 through December 2016. The cohorts included 31,498 men with IBD and 314,980 age-matched men without IBD. Our main outcome was a first prescription of an ED medication. Cox regression analyses were used to estimate the hazard rate (HR) for use of ED medications, controlled for multiple time-varying covariates. RESULTS Overall, 21,966 (69.7%) men had ulcerative colitis (UC) while 9532 (30.3%) had Crohn's disease (CD). Men with a first ED prescription numbered 3749 (11.9%) (men with IBD) and 30,635 (9.7%) (men without IBD). Adjusting for central nervous system and intestinal anti-inflammatory medications, systemic corticosteroids and co-morbidities, the HR was 1.19 (95% CI: 1.13-1.26) (IBD and no prior IBD operation), and 1.31 (95% CI: 1.20-1.43) (IBD and prior IBD operation). The adjusted HR for UC was 1.17 (95% CI: 1.10-1.24) (no operation) and 1.43 (95% CI: 1.27-1.61) (prior operation), and for CD 1.26 (95% CI: 1.15-1.38) (no operation) and 1.20 (95% CI: 1.06-1.35) (prior operation). DISCUSSION Men with IBD are more likely to fill an ED prescription than men without IBD. This result is significant regardless of a history of IBD surgery.

Abstract
Abstract
Introduction: Germline testing for BRCA1/2 genes provides an opportunity to reduce mortality and morbidity by adopting appropriate risk reduction and screening options, in particular with risk-reducing bilateral salpingo-oophorectomy (BSO).There is a paucity of data on Latinas and prophylactic measures among BRCA1/2 carriers.Existing studies are limited either by the small number of Latinas, or limited to a specific geographic location.Factors related to decision making have also not been evaluated.
Methods: The UPTAKE study is an observational study of Latinas with germline BRCA1/2 mutations.Subjects were recruited nationally and, by telephone interviews, reported uptake of prophylactic surgeries (BSO, bilateral mastectomy in unaffected women, and contralateral mastectomy in carriers with breast cancer (BC)). Women with ovarian cancer were ineligible. All women had to have been informed that they carried a deleterious BRCA1/2 mutation at least 1 year prior to completing the interview. The objectives of this study are: 1)to examine the rate of uptake of prophylactic surgeries; 2)identify acculturation and attitudinal factors related to decisions made and 3)examine relationships between primary language, receipt of genetic counseling (GC) and in which language it was provided and uptake of prophylactic surgeries. We plan to enroll 100 participants.
Results: As of 6/11/2017, 86 telephone interviews have been conducted. We anticipate that all 100 interviews will be completed by July 2017. 51.2% (44/86) of participants completed the interview in Spanish. Our population was diverse in terms of country of origin: 50.0% (43/86) were born in the US, 22.1% (19/86) in Mexico, 11.6% (10/86) in Puerto Rico, 4.6% (4/86) in El Salvador, 3.5% (3/86) in Ecuador and 8.1% (7/86) in other countries of Latin America. 30% (26/86) of the participants reported an annual household income inferior to $50.000. Only 26.7% (23/86) of women reported having a graduate degree. Approximately one quarter of participants were unemployed at the time of study participation (26.7%, 23/86). 34.9% (30/86) were unaffected and 62.8% (54/86) were affected with BC. 73.3% (63/86) of participants reported having received formal GC, of which only 28.6% (18/63) was conducted in Spanish. 66.3% (57/86) of women opted to undergo BSO and 58.1% (50/86) underwent prophylactic mastectomy. Being born outside the US and currently working were associated with higher uptake of BSO. Multivariate analysis will be performed once all interviews have been completed.
Conclusions: To our knowledge this is the largest study that evaluates uptake of prophylactic measures in Latinas known to be BRCA1/2 carriers. Our study included a heterogeneous group of participants in terms of country of origin, income and level of education including English knowledge. It was conducted across various academic and community centers in the country. The uptake of prophylactic surgeries among Latinas with germline BRCA mutations seems to be slightly lower than what has been reported in non-Hispanic whites (71-74%) but higher than in African Americans (32-50%). Results and factors associated with decision making will be updated once the total number of participants is enrolled.

Abstract
Drug and alcohol use have been associated with increased risk for sexual violence, but there is little research on sexual violence within the context of drug use among young adult opioid users. The current mixed-methods study explores young adult opioid users' sexual experiences in the context of their drug use. Forty-six New York City young adults (ages 18-32) who reported lifetime nonmedical use of prescription opioids (POs) completed in-depth, semistructured interviews, and 164 (ages 18-29) who reported heroin and/or nonmedical PO use in the past 30 days completed structured assessments that inquired about their drug use and sexual behavior and included questions specific to sexual violence. Participants reported frequent incidents of sexual violence experienced both personally and by their opioid using peers. Participants described sexual violence, including sexual assault, as occurring within a context characterized by victimization of users who were unconscious as a result of substance use, implicit and explicit exchanges of sex for drugs and/or money that increased risk for sexual violence, negative sexual perceptions ascribed to drug users, and participants' own internalized stigma. Recommendations to reduce sexual violence among young adult opioid users include education for users and service providers on the risk of involvement in sexual violence within drug using contexts and efforts to challenge perceptions of acceptability regarding sexual violence.

Abstract
OBJECTIVE Information on the safety of paternal use of azathioprine (AZA) and 6-mercaptopurine (6-MP) prior to conception is limited. Based on nationwide data from the Danish health registries, we examined the association between paternal use of AZA/6-MP within 3 months before conception and adverse birth outcomes. DESIGN This nationwide cohort study is based on data from all singletons born in Denmark from 1 January 1997 through 2013. Children fathered by men who used AZA/6-MP within 3 months before conception constituted the exposed cohort (N=699), and children fathered by men who did not use AZA/6-MP 3 months prior to conception constituted the unexposed cohort (N=1 012 624). The outcomes were congenital abnormalities (CAs), preterm birth and small for gestational age (SGA). We adjusted for multiple covariates and performed a restricted analysis of men with IBD. RESULTS There were no significantly increased risks of CAs, preterm birth or SGA in exposed versus unexposed cohorts of children. The adjusted ORs were 0.82 (95% CI 0.53 to 1.28) for CAs, 1.17 (95% CI 0.72 to 1.92) for preterm birth and 1.38 (95% CI 0.76 to 2.51) for SGA. Restricting our analysis to fathers with IBD showed similar results with no significantly increased risk of adverse birth outcomes. CONCLUSIONS This nationwide study is the largest to date, examining the effect of preconceptual paternal use of AZA/6-MP on birth outcomes in live born singletons. The results of no significantly increased risks of adverse birth outcomes are reassuring and support the continuation of paternal AZA/6-MP treatment during conception.

Abstract
There is currently widespread concern that access to, and success within, the British acting profession is increasingly dominated by those from privileged class origins. This article seeks to empirically interrogate this claim using data on actors from the Great British Class Survey (N = 404) and 47 qualitative interviews. First, survey data demonstrate that actors from working-class origins are significantly underrepresented within the profession. Second, they indicate that even when those from working-class origins do enter the profession they do not have access to the same economic, cultural and social capital as those from privileged backgrounds. Third, and most significantly, qualitative interviews reveal how these capitals shape the way actors can respond to shared occupational challenges. In particular we demonstrate the profound occupational advantages afforded to actors who can draw upon familial economic resources, legitimate embodied markers of class origin (such as Received Pronunciation) and a favourable typecasting.

Abstract
The hidden barriers, or 'gender pay gap', preventing women from earning equivalent incomes to men is well documented. Yet recent research has uncovered that, in Britain, there is also a comparable class-origin pay gap in higher professional and managerial occupations. So far this analysis has only been conducted at the national level and it is not known whether there are regional differences within the UK. This paper uses pooled data from the 2014 and 2015 Labour Force Survey (N = 7,534) to stage a more spatially sensitive analysis that examines regional variation in the class pay gap. We find that this 'class ceiling' is not evenly spatially distributed. Instead it is particularly marked in Central London, where those in high-status occupations who are from working-class backgrounds earn, on average, £10,660 less per year than those whose parents were in higher professional and managerial employment. Finally, we inspect the Capital further to reveal that the class pay gap is largest within Central London's banking and finance sector. Challenging policy conceptions of London as the 'engine room' of social mobility, these findings suggest that class disadvantage within high-status occupations is particularly acute in the Capital. The findings also underline the value of investigating regional differences in social mobility, and demonstrate how such analysis can unravel important and previously unrecognized spatial dimensions of class inequality.

Abstract
OBJECTIVE To examine the chance of live births and adverse birth outcomes in women with ulcerative colitis (UC) and Crohn's disease (CD) compared with women without inflammatory bowel disease (IBD) who have undergone assisted reproductive technology (ART) treatments. METHODS This was a nationwide cohort study based on Danish health registries, comprising all women with an embryo transfer during 1 January 1994 through 2013. The cohorts comprised 1360 ART treatments in 432 women with UC, 554 ART treatments in 182 women with CD and 148,540 treatments in 52,489 women without IBD. Our primary outcome was live births per ART treatment cycle. We controlled for multiple covariates in the analyses. Our secondary outcomes were adverse birth outcomes. RESULTS The chance of a live birth for each embryo transfer was significantly reduced in ART treatments in women with UC (OR=0.73, 95% CI 0.58 to 0.92), but not significantly reduced in the full model of ART treatments in women with CD (OR=0.77, 95% CI 0.52 to 1.14). Surgery for CD before ART treatment significantly reduced the chance of live birth for each embryo transfer (OR=0.51, 95% CI 0.29 to 0.91). In children conceived through ART treatment by women with UC, the OR of preterm birth was 5.29 (95% CI 2.41 to 11.63) in analyses including singletons and multiple births; restricted to singletons the OR was 1.80, 95% CI 0.49 to 6.62. CONCLUSIONS Our results suggest that women with UC and CD receiving ART treatments cannot expect the same success for each embryo transfer as other infertile women. Women with CD may seek to initiate ART treatment before needing CD surgery. Increased prenatal observation in UC pregnancies after ART should be considered.

Abstract
Women age 45 or under with breast cancer, or who are at high risk for breast cancer, have distinct health risks and needs when compared to their older counterparts. Young women with breast cancer or at high risk for breast cancer need evidence-based, high-quality information to help them make informed decisions about their specific health needs. Interpreting media reports on research findings, including determining the study implications for younger women is often challenging. To help women better understand media coverage of new research, Facing Our Risk of Cancer Empowered (FORCE) developed the CDC-funded XRAYS (eXamining Relevance of Articles to Young Survivors) program. To assure that the XRAYS program is responsive to the community's needs, FORCE launched a survey to assess where young women turn for information about breast cancer and to identify their information needs. The survey examines: how frequently women visit various media sources and health- or cancer-related websites for information on breast cancer screening, treatment, surgery, prevention, genetics, or survivorship; how much the women trust these information sources; whether they have ever tried to share media articles with their health care team and how the team received the information; and at what point(s) during the process of screening, diagnosis, treatment, survivorship and/or risk management respondents actively seek out information from the media. FORCE launched the survey nationally through its network of 50 outreach groups, partner organizations that serve young breast cancer survivors, and via a social media campaign targeting women age 45 and under with, or at high risk for breast cancer. The survey was open March 15 - June 30, 2015. We will report results from over 800 women, age 45 or younger, including those with breast cancer, who have previously had breast cancer, or who are at high risk for breast cancer. Analysis will determine response frequencies and whether information needs and utilization correlate with key demographic variables such as race/ethnicity, education, and income level. We will use correlation and multiple regression analysis to assess patterns in the types of information needed and channels where information is sought. These results will ensure XRAYS materials and dissemination efforts are efficient and responsive to the young breast cancer population's needs, and will inform the broader medical, media and patient advocacy communities about the distinct information needs of this group.

Abstract
Abstract
Background: Distress levels among female BRCA1 and BRCA2 mutation carriers can be similar to levels reported among breast cancer patients. However, there is a lack of data on long-term psychosocial functioning, and it is not known if uptake of risk-reducing surgery influences long-term cancer related distress in women with a BRCA mutation who are unaffected with cancer. The objective of this study was to evaluate long-term cancer-related distress in women with a BRCA mutation, and to evaluate predictors of distress, including uptake of cancer risk reducing surgery.
Methods: Female BRCA1 or BRCA2 mutation carriers, ages 25-55, and without cancer were eligible to complete the survey online. A validated instrument, Impact of Events Scale (IES)-Revised (Horowitz 1979, Weis & Marmar 1995; 0-80 overall scale), was used to assess current levels of cancer risk-related psychological distress. Respondents were recruited through the Facing Our Risk of Cancer Empowered (FORCE) advocacy organization, which includes women at high risk of breast cancer. This interim analysis is part of a larger multi-center patient preference study of BRCA mutation carriers designed to assess women's willingness to adopt hypothetical treatments to prevent breast cancer. Linear regression was used to evaluate predictors of IES distress levels.
Results: Between January and April 2015, 259 women completed the survey. The mean age of the participants was 41 years, and the mean time since receipt of genetic test results was 3.5 years (range 0-16; median 2 years). One hundred thirty-six (52%) women elected for prophylactic bilateral mastectomy (PBM), 139 (54%) elected for bilateral salpingo oophorectomy (BSO) (93 [36%] women had both surgeries), and 77 (30%) had not undergone risk-reducing surgery. The mean total IES score was 15.1 (range 0-72; median 11). Overall, 54 (21%) women reported moderate or severe cancer-related distress, and those who had undergone risk-reducing surgery reported lower perceived risk of developing breast cancer. Results to date indicate that shorter time since notification of mutation status, not having PBM (with or without BSO) (table), and not completing post-secondary education were independent predictors of higher IES distress scores.

Conclusions: This study measured cancer-related distress in a large population of women with BRCA mutations who participate in the FORCE online support community. Higher levels of distress were associated with not having PBM and more recent genetic test disclosure. These findings are specific to a more informed community of women with high levels of understanding of cancer risk than may be seen in the clinical setting.

Abstract
BACKGROUND Knowledge of the extent and the impact of sexual dysfunction and interpersonal relationships in men with inflammatory bowel disease is scarce. AIMS The aim of this review article was to summarise the current literature on sexual function in male patients with IBD and to provide a critical review of the IBD-related medical, surgical and psychological complications that can result in impaired quality of sexual health. METHODS To collect relevant articles, PubMed/Medline and Embase searches were performed using Boolean search phrases. RESULTS Reported rates of sexual dysfunction in male IBD patients range from 10% to 50%. Thirty-three to fifty per cent of patients report that sexual desire and satisfaction deteriorated after IBD diagnosis. Of those patients who were sexually inactive, half of these attributed lack of intercourse to underlying IBD. A striking finding reproduced in numerous studies is that disease activity relates strongly to impaired psychological function, and the most consistently reported risk factor for sexual problems in IBD patients is co-existing mood disorders. Hypogonadism is a complication of IBD and its therapies, the role of testosterone deficiency should be further explored as a potentially treatable and reversible factor in sexual dysfunction. CONCLUSIONS By understanding what factors contribute to poor sexual functioning in our patients, we can strive to minimise adverse psychosocial events. Further insight into this complex relationship requires an IBD-specific measure of sexual function in male patients. We recommend screening for and treating co-morbid depression, testosterone deficiency and striving for clinical remission to prevent psychosexual dysfunction in male patients with inflammatory bowel disease.

Abstract
BACKGROUND AND AIM Adipose tissue produces different metalloproteinases (MMPs), involved in adipogenesis and angiogenesis. Different studies have shown that in obesity the behavior of different MMPs may be altered. However there are scarce data about the effect of insulin-resistance (IR) on MMP-2 and MMP-9 activity in adipose tissue. Our aim was to determine whether sucrose induced IR modifies MMP-2 and MMP-9 behavior in expanded visceral adipose tissue and the contribution of this tissue to circulating activity of these gelatinases. METHODS AND RESULTS Male Wistar rats were fed with standard diet (Control) or standard diet plus 30% sucrose in the drinking water throughout 12 weeks (SRD). In epididymal adipose tissue vascular density, size and adipocyte density, PPARγ expression and MMP-2 and -9 were measured. Adipose tissue from SRD presented higher adipocyte size (6.32 ± 8.71 vs 4.33 ± 2.17 × 10(3) μm(2), p = 0.001) lower adipocyte density (164 (130-173) vs 190 (170-225) number/mm(2), p = 0.046) and lower vascular density (16.2 (12.8-23.5) vs 28.1 (22.3-46.5) blood vessels/mm(2), p = 0.002) than Control. MMP-2 and MMP-9 activity was decreased in SRD (1.93 ± 0.7 vs 3.92 ± 0.9 relative units, p = 0.048 and 1.80 ± 0.8 vs 5.13 ± 1.7 relative units, p = 0.004 respectively) in accordance with lower protein expression (0.35 ± 0.20 vs 2.71 ± 0.48 relative units, p = 0.004 and 1.12 ± 0.21 vs 1.52 ± 0.05 relative units, p = 0.036 respectively). There were no differences in PPARγ expression between groups. CONCLUSION Insulin resistance induced by SRD decreases MMP-2 and MMP-9 activity in adipose tissue which would not represent an important source for circulating MMP-2 and -9. In this state of IR, PPARγ would not be involved in the negative regulation of adipose tissue gelatinases.

Abstract
As they age, gay and bisexual men are embedded in multiple environments and communities. This article reanalyzes data collected as part of a larger qualitative study of crystal methamphetamine use in New York City. Focusing on the migration narratives of 30 racially/ethnically diverse men, age 40 years old and older, recruited from multiple venues several key areas emerged: ostracization, lack of affirmation as well as movement activities. Interactively they transformed social practices and increased spaces to explore sexuality, build community engagements and exchange resources. This study suggests that assessment of gay men (and other marginalized groups) may be enhanced through application of migration narratives.

Abstract
INTRODUCTION The Brazilian public health system requires competent professionals sensitive to the needs of the population. The Foundation for Advancement of International Medical Education and Research (FAIMER) provides a two-year faculty development programme for health professions educators, aiming to build leadership in education to improve health. A partnership with governmental initiatives and FAIMER was established for meeting these needs. This paper describes the initial process evaluation results of the Brazilian FAIMER Institute Fellowship (FAIMER BR). METHODS Data were analysed for the classes 2007-2010 regarding: application processes; innovation project themes; retrospective post-pre self-ratings of knowledge acquisition; and professional development portfolios. RESULTS Seventeen of 26 Brazilian states were represented among 98 Fellows, predominantly from public medical schools (75.5%) and schools awarded Ministry of Health grants to align education with public health services (89.8%). One-third (n = 32) of Fellows' innovation projects were related to these grants. Significant increases occurred in all topic subscales on self-report of knowledge acquisition (effect sizes, 1.21-2.77). In the follow up questionnaire, 63% of Fellows reported that their projects were incorporated into the curriculum or institutional policies. The majority reported that the programme deepened their knowledge (98%), provided new ideas about medical education (90%) and provided skills for conflict management (63%). One-half of the Fellows reported sustained benefits from the programme listserv and other communications, including breadth of expertise, establishment of research collaboration and receiving emotional support. CONCLUSION Contributors to initial programme success included alignment of curriculum with governmental initiatives, curriculum design merging educational technology, leadership and management skills and central role of an innovation educational project responding to local needs.

Abstract
Understanding the dynamics of sexual risks for HIV among men who have sex with men has been one of the ongoing challenges of HIV prevention. While the majority of HIV-prevention interventions target individual behaviour and decision making, multiple studies point to the importance of social context in shaping risk behaviour. Analysis of qualitative data from a study of men who have sex with men, drug use and sex found that sexual encounters were made up multiple contextual and interpersonal elements, which interacted to shape sexual practices and risk reduction strategies. Semi-structured interviews were conducted with 60 racially diverse men who have sex with men in NYC, recruited from multiple venues. The majority of respondents were gay-identified and half were 40 or older. Respondents described risk assessment and risk-reduction processes that develop throughout a sexual encounter, embedded in ongoing negotiations of sexual practices. Strategies of risk assessment and reduction draw on probability-based approaches to HIV prevention, presenting a challenge to health education.

Abstract
Traditionally considered lowbrow art par excellence, British comedy has grown steadily in legitimacy since the 'Alternative Comedy Movement' of the early 1980s. Yet while there might be evidence of a transformation in British comic production, there is little understanding of how this has been reflected in patterns of consumption. Indeed, there is a remarkable absence of studies probing comedy taste in British cultural sociology, most notably in Bennett et al's (2009) recent and otherwise exhaustive mapping of cultural taste and participation. This paper aims to plug this gap in the literature by examining contemporary comedy taste cultures in Britain. Drawing on a large-scale survey and in-depth interviews carried out at the Edinburgh Festival Fringe, it argues that comedy now represents an emerging field for the culturally privileged to activate their cultural capital resources. However, unlike previous studies on cultural capital and taste, this research finds that field-specific 'comic cultural capital' is mobilized less through taste for certain legitimate 'objects' of comedy and more through the expression of rarefied and somewhat 'disinterested'styles of comic appreciation. In short, it is 'embodied' rather than 'objectified' forms of cultural capital that largely distinguish the privileged in the field of comedy.
