RESUMO
Sexual minority populations experience a higher burden of mental health and substance use/misuse conditions than heterosexual comparators-a health inequality that has predominantly been attributed to forms of minority stress experienced by the former group. Sexual minority-affirming legislative and policy advances, as well as improvements in social attitudes toward sexual minorities in recent decades, should presumably reduce experiences of minority stress, thereby attenuating these disparities. We conducted temporal trend analyses of annual prevalence of anxiety, depression, poor self-rated mental health, and cigarette smoking, stratified by sexual orientation and gender/sex subgroups using the Canadian Community Health Survey, 2003-2020. Descriptive analyses were used to display temporal trends; joinpoint regression was used to identify significant changes in prevalence data during 2003-2020; and prevalence ratios were estimated by year to detect any reduction in disparities. The prevalence of self-rated mental health and mood and anxiety disorders increased, whereas the prevalence of smoking decreased, between 2003 and 2020, among both sexual minority and heterosexual people in Canada. We observed a significant inflection point in 2009 in the self-rated mental health trend among bisexual women, where rates of poor mental health initially decreased from 2003 but then increased drastically from 2009 to 2020. Significant inflection points in current smoking trends were observed in 2012 among bisexual and heterosexual women and in 2013 among heterosexual men; in all three groups, both segments demonstrated decreasing trends, however, the slope of the trend became more pronounced in the latter period. Consistent with other North American studies, we found that relative differences between sexual minority and heterosexual groups for all four outcomes remained the same or increased during this 18-year period. Findings highlight the need to better understand mechanisms bolstering sexual orientation health disparities.
RESUMO
The prevalence and relative disparities of mental health outcomes and well-being indicators are often inconsistent across studies of Sexual Minority Men (SMM) due to selection biases in community-based surveys (non-probability sample), as well as misclassification biases in population-based surveys where some SMM often conceal their sexual orientation identities. The current paper estimated the prevalence of mental health related outcomes (depressive symptoms, mental health service use [MHSU], anxiety) and well-being indicators (loneliness and self-rated mental health) among SMM, broken down by sexual orientation using the Adjusted Logistic Propensity score (ALP) weighting. We applied the ALP to correct for selection biases in the 2019 Sex Now data (a community-based survey of SMMs in Canada) by reweighting it to the 2015-2018 Canadian Community Health Survey (a population survey from Statistics Canada). For all SMMs, the ALP-weighted prevalence of depressive symptoms is 15.96% (95% CI: 11.36%, 23.83%), while for MHSU, it is 32.13% (95% CI: 26.09, 41.20). The ALP estimates lie in between the crude estimates from the two surveys. This method was successful in providing a more accurate estimate than relying on results from one survey alone. We recommend to the use of ALP on other minority populations under certain assumptions.
RESUMO
Transgender women of color (TWOC) experience high rates of police violence and victimization compared to other sexual and gender minority groups, as well as compared to other White transgender and cisgender women. While past studies have demonstrated how frequent police harassment is associated with higher psychological distress, the effect of neighborhood safety and neighborhood police violence on TWOC's mental health is rarely studied. In this study, we examine the association between neighborhood safety and neighborhood police violence with psychological distress among TWOC. Baseline self-reported data are from the TURNNT ("Trying to Understand Relationships, Networks and Neighborhoods among Transgender Woman of Color") Cohort Study (analytic n = 303). Recruitment for the study began September 2020 and ended November 2022. Eligibility criteria included being a TWOC, age 18-55, English- or Spanish-speaking, and planning to reside in the New York City metropolitan area for at least 1 year. In multivariable analyses, neighborhood safety and neighborhood police violence were associated with psychological distress. For example, individuals who reported medium levels of neighborhood police violence had 1.15 [1.03, 1.28] times the odds of experiencing psychological distress compared to those who experienced low levels of neighborhood police violence. Our data suggest that neighborhood safety and neighborhood police violence were associated with increased psychological distress among TWOC. Policies and programs to address neighborhood police violence (such as body cameras and legal consequences for abusive officers) may improve mental health among TWOC.

BACKGROUND: Adverse childhood experiences (ACE) are important predictors of mental health outcomes in adulthood. However, commonly used ACE measures such as the Behavioural Risk Factor Surveillance System (BRFSS) have not been validated among Black sexually minoritized men (SMM) nor transgender women (TW), whom are known to have higher rates of ACE and poorer mental health outcomes. Assessing the psychometric properties of the measure is important for health equity research, as measurements that are not valid for some populations will render uninterpretable results. METHODS: Data are drawn from the Neighborhoods and Networks (N2) study, a longitudinal cohort of Black SMM and TW living in Southern Chicago. We conducted confirmatory factor analysis, correlation analysis and a two-parameter Item Response Theory (IRT) on the BRFSS ACE measure, an 11-item measure with 8 domains of ACE. RESULTS: One hundred forty seven participants (85% cisgender male) completed the BRFSS ACE measurement in the N2 study with age ranges from 16-34. The cohort were from a low socioeconomic background: about 40% of the cohort were housing insecure and made than $10,000 or less annually. They also have a high number of ACEs; 34% had endorsed 4 or more ACE domains. The three-factor structure fit the BRFSS ACE measure best; the measurement consisted of three subscales: of "Household Dysfunction", "Emotional / Physical", and "Sexual Abuse" (CFI = 0.975, TLI = 0.967, and RMSEA = 0.051). When the 8 domains of ACE were summed to one score, the total score was is correlated with depressive symptoms and anxiety scores, establishing concurrent validity. Item Response Theory model indicated that the "parental separation" domain had a low discrimination (slope) parameter, suggesting that this domain does not distinguish well between those with and without high ACE. CONCLUSIONS: The BRFFS ACE measure had adequate reliability, a well-replicated structure and some moderate evidence of concurrent validity among Black SMM and TW. The parental separation domain does not discriminate between those with high and low ACE experiences in this population. With changing population demographics and trends in marriage, further examination of this item beyond the current study is warranted to improve health equity research for all.

BACKGROUND: Substance use is increasing among sexual and gender minority youth (SGMY). This increase may be due to changes in social norms and socialisation, or due to SGMY exploring the potential therapeutic value of drugs such as psychedelics. We identified predictors of psychedelics, MDMA and ketamine use. METHODS: Data were obtained from 1414 SGMY participants who completed the ongoing longitudinal 2SLGBTQ+ Tobacco Project in Canada between November 2020 to January 2021. We examined the association between 80 potential features (including sociodemographic factors, mental health-related factors and substance use-related factors) with the use of psychedelics, MDMA and ketamine in the past year. Random forest classifier was used to identify the predictors most associated with reported use of these drugs. RESULTS: 18.1% of participants have used psychedelics in the past year; 21.9% used at least one of the three drugs. Cannabis and cocaine use were the predictors most strongly associated with any of these drugs, while cannabis, but not cocaine use, was the one most associated with psychedelic use. Other mental health and 2SLGBTQ+ stigma-related factors were also associated with the use of these drugs. CONCLUSION: The use of psychedelics, MDMA and ketamine among 2SLGBTQ+ individuals appeared to be largely driven by those who used them together with other drugs. Depression scores also appeared in the top 10 factors associated with these illicit drugs, suggesting that there were individuals who may benefit from the potential therapeutic value of these drugs. These characteristics should be further investigated in future studies.

There is a lack of rigorous methodological development for descriptive epidemiology, where the goal is to describe and identify the most important associations with an outcome given a large set of potential predictors. This has often led to the Table 2 fallacy, where one presents the coefficient estimates for all covariates from a single multivariable regression model, which are often uninterpretable in a descriptive analysis. We argue that machine learning (ML) is a potential solution to this problem. We illustrate the power of ML with an example analysis identifying the most important predictors of alcohol abuse among sexual minority youth. The framework we propose for this analysis is as follows: (1) Identify a few ML methods for the analysis, (2) optimize the parameters using the whole data with a nested cross-validation approach, (3) rank the variables using variable importance scores, (4) present partial dependence plots (PDP) to illustrate the association between the important variables and the outcome, (5) and identify the strength of the interaction terms using the PDPs. We discuss the potential strengths and weaknesses of using ML methods for descriptive analysis and future directions for research. R codes to reproduce these analyses are provided, which we invite other researchers to use.

BACKGROUND: Patients with thrombophilia are underrepresented in studies evaluating outcomes after closure of patent foramen ovale (PFO). Real-world data on long term outcomes in this population are very limited. OBJECTIVES: This study compared outcomes in patients with and without thrombophilia undergoing PFO closure, using data from a large, clinical database linked to population-based databases. METHODS: This retrospective cohort study included consecutive patients who had a transcatheter PFO closure and had preprocedural thrombophilia screening. Data from a retrospective, clinical registry were linked to population-based administrative databases in Ontario Canada to evaluate outcomes. Outcomes were reported as rates per 100 person-years and compared using Poisson regression. RESULTS: We included 669 patients, with a mean age of 56.4 years, 97.9% of whom underwent PFO closure for a cryptogenic stroke. Thrombophilia was diagnosed among 174 (26.0%), of which 86% had inherited mutations. In-hospital, procedural complications were observed in 3.1% of patients with no difference by thrombophilia status. Similarly, no differences were observed in 30-day emergency department visits and readmissions. Over the median follow-up of 11.6 years, the most common adverse outcome was new-onset atrial fibrillation (1.0 per 100 person-years; 95% CI: 0.8-1.2), followed by recurrent cerebrovascular events (0.8 per 100 person-years; 95% CI: 0.6-1.1) with no differences between the groups (P > 0.05). CONCLUSIONS: After PFO closure, no differences were observed in long-term adverse outcomes between patients with and without thrombophilia. Though these patients have been excluded from randomized clinical trials of PFO closure in the past, real-world evidence supports their eligibility for the procedure.

BACKGROUND: Systemic administration of heparin is widely used in patients undergoing open elective abdominal aortic aneurysm (AAA) repair. However, no clear consensus exists in the use of intraoperative heparin during open ruptured AAA (rAAA) repair. In this study, we assessed the safety of intravenous heparin administration in patients undergoing open rAAA repair. METHODS: A retrospective cohort study comparing patients who received and did not receive heparin during open rAAA repair in the Vascular Quality Initiative database between 2003 and 2020 was conducted. The primary outcomes were 30-day and 10-year mortality. The secondary outcomes included estimated blood loss, number of packed red blood cells transfused, early postoperative transfusions, and postsurgical complications. Propensity score matching was used to adjust for potentially confounding variables. The outcomes were compared between the 2 groups using relative risk for binary outcomes and paired t-test and the Wilcoxon rank-sum test for normally and non-normally distributed continuous variables, respectively. Survival was examined using Kaplan-Meier curves and compared using a Cox proportional hazards model. RESULTS: A total of 2,410 patients who underwent open rAAA repair between 2003 and 2020 were studied. Of the 2,410 patients, 1,853 patients received intraoperative heparin and 557 did not. Propensity score matching on 25 variables yielded 519 pairs for the heparin to no heparin comparison. Thirty-day mortality was lower in the heparin group (risk ratio: 0.74; 95% confidence interval [CI]: 0.66-0.84) and in-hospital was also lower in the heparin group (risk ratio: 0.68; 95% CI: 0.60-0.77). Furthermore, estimated blood loss was 910 mL (95% CI: 230 mL to 1,590 mL) lower in the heparin group and the mean number of packed red blood cells transfused intraoperatively and postoperatively were 17 units lower in the heparin group (95% CI: 8-42). Ten-year survival was higher for patients who received heparin, and their rate of survival was approximately 40% higher than those who did not receive heparin (hazard ratio: 0.62; 95% CI, 0.53-0.72; P < 0.0001). CONCLUSIONS: In patients who received systemic heparin administration at the time of open rAAA repair, there were significant short-term and long-term survival benefits within 30 days and at 10 years. Heparin administration may have afforded a mortality benefit or been a surrogate for healthier and less moribund patients at the time of the procedure.

BACKGROUND: Social geography plays an important role in transmission of sexually transmitted infections (STIs) among men who have sex with men. Previous qualitative work had identified 7 "geosexual archetypes," each with distinct travel patterns for sex and potentially important differences in STI rates. The objective of this article was to explore what could be learned about STI transmission by looking at STI prevention strategies (condom use and preexposure prophylaxis use) and prevalence of STIs among these geosexual archetypes. METHODS: We analyzed data from the Sex Now 2019 online survey in Canada. Men who have sex with men who reported 3 or more partners in the past 6 months were included in the analysis (n = 3649). RESULTS: The most common archetype was "geoflexible" (sex at home, partner's home, and other places; 35.6%), followed by "privates" (sex only at own/partner's home; 23.0%); the least common archetypes was "rover" (sex not at home or partner's place; 4.0%). There were significant variations in both STI prevention strategies and prevalence of bacterial STIs in the past year by geosexual archetype. In particular, among those who were HIV negative, those who reported a geoflexible archetype and used preexposure prophylaxis but did not use condoms consistently had a 52.6% prevalence of bacterial STIs, which was much higher compared with all other groups. Within other archetypes, those living with HIV had the highest prevalence of bacterial STIs. CONCLUSIONS: Geosexual archetype together with participant's STI prevention strategies was a strong predictor of bacterial STI risk. Understanding how place is connected to bacterial STIs is key in prevention as individuals do not live in isolation.

BACKGROUND: Patent foramen ovale (PFO) is a congenital heart defect associated with an increased risk of cryptogenic stroke. We aimed to evaluate real-world outcomes of adult patients undergoing transcatheter PFO closure with the Amplatzer PFO Occluder. METHODS: In this single centre, retrospective cohort study, we linked a detailed clinical registry with provincial administrative databases to obtain short and long-term outcomes. Validated algorithms were used to established baseline comorbidities and adverse outcomes. RESULTS: Between 1999 and 2017, 479 patients had PFO closure with an Amplatzer PFO Occluder. The average age of the patients was 47.3 years (standard deviation (SD) = 12.4), and 54.7% were males. The procedural success was 100%, and 96% of patients were discharged on the same day. Any in-hospital complication was observed in 2.5% (n = 12) of patients. At 30 days post-discharge, 18% of patients had an ED visit and 5% a hospitalization. Over a mean follow-up of 9.1 (SD = 3.8) years, 4% experienced TIA, 1.5% stroke, and 7.6% atrial fibrillation. The composite outcome of stroke/TIA/death was observed in 10.9% of patients (1.22 events per 100 person-years). Patients >60 years old experienced higher rates of adverse events than younger patients. CONCLUSIONS: In this large real-world cohort of patients with cryptogenic stroke, we observed excellent safety and effectiveness outcomes for PFO closure conducted with Amplatzer PFO Occluder, similar to randomized controlled trials or other long-term cohort studies. New onset atrial fibrillation was one of the most commonly adverse events. Future studies should investigate early post-discharge management of patients to prevent readmissions.

The COVID-19 pandemic has touched many aspects of people's lives around the world, including their romantic relationships. While media outlets have reported that the pandemic is difficult for couples, empirical evidence is needed to test these claims and understand why this may be. In two highly powered studies (N = 3271) using repeated measure and longitudinal approaches, we found that people who experienced COVID-19 related challenges (i.e., lockdown, reduced face-to-face interactions, boredom, or worry) also reported greater self and partner phone use (Study 1) and time spent on social media (Study 2), and subsequently experienced more conflict and less satisfaction in their romantic relationship. The findings provide insight into the struggles people faced in their relationships during the pandemic and suggest that the increase in screen time - a rising phenomenon due to the migration of many parts of life online - may be a challenge for couples.
RESUMO
Importance: Despite advances in asthma therapeutics, the burden remains highest in preschool children; therefore, it is critical to identify primary care tools that distinguish preschool children at high risk for burdensome disease for further evaluation. Current asthma prediction tools, such as the modified Asthma Predictive Index (mAPI), require invasive tests, limiting their applicability in primary care and low-resource settings. Objective: To develop and evaluate the use of a symptom-based screening tool to detect children at high risk of asthma, persistent wheeze symptoms, and health care burden. Design, Setting, and Participants: The cohort for this diagnostic study included participants from the CHILD Study (n = 2511) from January 1, 2008, to December 31, 2012, the Raine Study from January 1, 1989, to December 31, 2012 (n = 2185), and the Canadian Asthma Primary Prevention Study (CAPPS) from January 1, 1989, to December 31, 1995 (n = 349), with active follow-up to date. Data analysis was performed from November 1, 2019, to May 31, 2022. Exposures: The CHILDhood Asthma Risk Tool (CHART) identified factors associated with asthma in patients at 3 years of age (timing and number of wheeze or cough episodes, use of asthma medications, and emergency department visits or hospitalizations for asthma or wheeze) to identify children with asthma or persistent symptoms at 5 years of age. Main Outcomes and Measures: Within the CHILD Study cohort, CHART was evaluated against specialist clinician diagnosis and the mAPI. External validation was performed in both a general population cohort (Raine Study [Australia]) and a high-risk cohort (CAPPS [Canada]). Predictive accuracy was measured by sensitivity, specificity, area under the receiver operating characteristic curve (AUROC), and positive and negative predicted values. Results: Among 2511 children (mean [SD] age at 3-year clinic visit, 3.08 [0.17] years; 1324 [52.7%] male; 1608 of 2476 [64.9%] White) with sufficient questionnaire data to apply CHART at 3 years of age, 2354 (93.7%) had available outcome data at 5 years of age. CHART applied in the CHILD Study at 3 years of age outperformed physician assessments and the mAPI in predicting persistent wheeze (AUROC, 0.94; 95% CI, 0.90-0.97), asthma diagnosis (AUROC, 0.73; 95% CI, 0.69-0.77), and health care use (emergency department visits or hospitalization for wheeze or asthma) (AUROC, 0.70; 95% CI, 0.61-0.78). CHART had a similar predictive performance for persistent wheeze in the Raine Study (N = 2185) in children at 5 years of age (AUROC, 0.82; 95% CI, 0.79-0.86) and CAPPS (N = 349) at 7 years of age (AUROC, 0.87; 95% CI, 0.80-0.94). Conclusions and Relevance: In this diagnostic study, CHART was able to identify children at high risk of asthma at as early as 3 years of age. CHART could be easily incorporated as a routine screening tool in primary care to identify children who need monitoring, timely symptom control, and introduction of preventive therapies.

INTRODUCTION: Several androgen deprivation therapy (ADT) medications are available for treating advanced prostate cancer with roughly equivalent oncological efficacy and tolerability. We investigated the proportion of physicians who predominantly prescribe one type of ADT drug ("mono-prescriber") and assessed characteristics associated with prescription behavior. METHODS: Ontario men aged ≥65 years who were diagnosed with advanced prostate cancer (1997-2017) and initiated ADT thereafter for ≥3 consecutive months were identified using population-level administrative data. Their first prescription for injectable ADT was linked to a physician, and urologists with ≥10 prescriptions over the study period were included in the analysis (n=282). Urologists were classified as high mono-prescribers if ≥80% of their prescriptions were for one drug type. Multivariable logistic regression was used to examine the association of physician characteristics with the odds of being a high mono-prescriber. RESULTS: Overall, 67 (23.8%) of urologists were classified as high mono-prescribers but the frequency varied across health planning regions. The most commonly prescribed drugs and those used by mono-prescribers were goserelin (41.8% and 56.7%) and leuprolide (44.3% and 43.3%), respectively. In multivariable analysis, the odds of a physician being a high mono-prescriber were higher with more years in practice (odds ratio [OR] 1.06/year, 95% confidence interval [CI] 1.03-1.09, p<0.0001) and lower for higher patient volume (OR 0.33 for above vs. below median, 95% CI 0.17-0.63, p=0.0008). CONCLUSIONS: Overall, one in four urologists were classified as high mono-prescribers. Mono-prescribers had more years in practice and smaller volume practices, potentially suggesting habitual prescription behavior and/or the effect of external pressures.
RESUMO
BACKGROUND: Functional tricuspid regurgitation (TR) is a common pathophysiologic condition in adults with ostium secundum atrial septal defect (ASD). The aim of this study was to evaluate long-term outcomes following transcatheter ASD closure, which have not been well studied among patients with significant TR. METHODS: We reviewed consecutive adult patients who underwent transcatheter ASD closure at Toronto General Hospital, Ontario, Canada, from 1998 to 2016. We linked our hospital registry with Ontario population-based health administrative databases to collect longitudinal data on inpatient and outpatient health care utilisation and vital status. RESULTS: In this cohort study of 949 patients, 199 (22%) had moderate to severe TR before transcatheter ASD closure. A significant proportion of patients (61%) showed improvement in TR severity to at least mild TR after ASD intervention. At a median follow-up of 10.9 years, patients with baseline mild or no TR, compared with those with greater than moderate TR, had significantly lower rates of all-cause mortality (6.8 vs 22.5 per 1000 person-years [PY]; P < 0.001), composite hospitalisation for atrial fibrillation (AF) or heart failure (HF) (22.3 vs 49.1 per 1000 PY; P < 0.001), and new onset of AF (10.4 vs 20.2 per 1000 PY; P = 0.002) and HF (5.0 vs 9.2 per 1000 PY; P = 0.039). Preprocedural TR was independently associated with higher all-cause mortality (adjusted hazard ratio 1.69, 95% confidence interval 1.08-2.62). CONCLUSIONS: TR severity was independently associated with a higher risk of mortality and morbidity. Further investigation of earlier device closure or concomitant tricuspid valve intervention may be of interest.

OBJECTIVES: The long-term outcomes after transcatheter closure of atrial septal defects (ASD) in adults are reported and compared between age groups and against population control patients. BACKGROUND: ASD is the second most common lesion in congenital heart disease. Comprehensive data on long-term outcomes after ASD closure are limited. METHODS: This retrospective cohort study enrolled adult patients with secundum ASD closure between 1998 and 2016. Information from a detailed clinical registry was linked to population-based administrative databases to capture outcomes. The population control cohort was matched using important prognostic characteristics. RESULTS: The cohort included 1,390 ASD patients of whom 32% were <40 years of age, 45% were 40 to 60 years of age, and 23% were >60 years of age at closure. The median follow-up was 10.6 years (interquartile range: 6.2 to 14.0 years). New-onset atrial fibrillation (AF) was the most frequent outcome overall (14.9%). The incidence of adverse cardiac and cerebrovascular events was higher in the >60 years of age group than in the younger groups. In adjusted analysis, patients >60 years of age continued exhibiting higher risk of all-cause (hazard ratio [HR]: 8.54; 95% confidence interval [CI]: 93.40 to 21.43) and cardiovascular (CV)-specific mortality compared with the <40 years of age group. The risk of new-onset AF (HR: 3.73; 95% CI: 2.79 to 4.98) and any AF hospitalization (HR: 1.55; 95% CI: 1.28 to 1.89) was higher in the ASD than in the control population, whereas there was no difference in all-cause and CV-specific mortality. CONCLUSIONS: As expected, rates of adverse events post-ASD closure are higher in older age groups, but long-term mortality was comparable to that of a population control cohort. The high rates of AF necessitate future investigations.

Importance: Intraoperative anesthesiology care is crucial to high-quality surgical care. The clinical expertise and experience of anesthesiologists may decrease the risk of adverse outcomes. Objective: To examine the association between anesthesiologist volume and short-term postoperative outcomes for complex gastrointestinal (GI) cancer surgery. Design, Setting, and Participants: This population-based cohort study used administrative health care data sets from various data sources in Ontario, Canada. Adult patients who underwent esophagectomy, pancreatectomy, or hepatectomy for GI cancer from January 1, 2007, to December 31, 2018, were eligible. Patients with an invalid identification number, a duplicate surgery record, and missing primary anesthesiologist information were excluded. Exposures: Primary anesthesiologist volume was defined as the annual number of procedures of interest (esophagectomy, pancreatectomy, and hepatectomy) supported by that anesthesiologist in the 2 years before the index surgery. Volume was dichotomized into low-volume and high-volume categories, with 75th percentile or 6 or more procedures per year selected as the cutoff point. Main Outcome and Measures: The primary outcome was a composite of 90-day major morbidity (with a Clavien-Dindo classification grade 3-5) and readmission. Secondary outcomes were individual components of the primary outcome. The association between exposure and outcomes was examined using multivariable logistic regression models, accounting for potential confounders. Results: Of the 8096 patients included, 5369 were men (66.3%) and the median (interquartile range [IQR]) age was 65 (57-72) years. Operations were supported by 842 anesthesiologists and performed by 186 surgeons, and the median (IQR) anesthesiologist volume was 3 (1.5-6) procedures per year. A total of 2166 patients (26.7%) received care from high-volume anesthesiologists. Primary outcome occurred in 36.3% of patients in the high-volume group and 45.7% of patients in the low-volume group. After adjustment, care by high-volume anesthesiologists was independently associated with lower odds of the primary outcome (adjusted odds ratio [aOR], 0.85; 95% CI, 0.76-0.94), major morbidity (aOR, 0.83; 95% CI, 0.75-0.91), unplanned intensive care unit admission (aOR, 0.84; 95% CI, 0.76-0.94), but not readmission (aOR, 0.87; 95% CI, 0.73-1.05) or mortality (aOR, 1.05; 95% CI, 0.84-1.31). E-values analysis indicated that an unmeasured variable would unlikely substantively change the observed risk estimates. Conclusions and Relevance: This study found that, among adults who underwent complex gastrointestinal cancer surgery, those who received care from high-volume anesthesiologists had a lower risk of adverse postoperative outcomes compared with those who received care from low-volume anesthesiologists. These findings support organizing perioperative care to increase anesthesiologist volume to optimize patient outcomes.

New guidelines for peanut allergy prevention in high-risk infants recommend introducing peanut during infancy but do not address breastfeeding or maternal peanut consumption. We assessed the independent and combined association of these factors with peanut sensitization in the general population CHILD birth cohort (N = 2759 mother-child dyads). Mothers reported peanut consumption during pregnancy, timing of first infant peanut consumption, and length of breastfeeding duration. Child peanut sensitization was determined by skin prick testing at 1, 3, and 5 years. Overall, 69% of mothers regularly consumed peanuts and 36% of infants were fed peanut in the first year (20% while breastfeeding and 16% after breastfeeding cessation). Infants who were introduced to peanut early (before 1 year) after breastfeeding cessation had a 66% reduced risk of sensitization at 5 years compared to those who were not (1.9% vs. 5.8% sensitization; aOR 0.34, 95% CI 0.14-0.68). This risk was further reduced if mothers introduced peanut early while breastfeeding and regularly consumed peanut themselves (0.3% sensitization; aOR 0.07, 0.01-0.25). In longitudinal analyses, these associations were driven by a higher odds of outgrowing early sensitization and a lower odds of late-onset sensitization. There was no apparent benefit (or harm) from maternal peanut consumption without breastfeeding. Taken together, these results suggest the combination of maternal peanut consumption and breastfeeding at the time of peanut introduction during infancy may help to decrease the risk of peanut sensitization. Mechanistic and clinical intervention studies are needed to confirm and understand this "triple exposure" hypothesis.

BACKGROUND: There remains a paucity of real-world observational evidence comparing percutaneous coronary intervention (PCI) with coronary artery bypass grafting (CABG) in patients with diabetes and multivessel coronary artery disease (CAD). OBJECTIVES: This study compared early and long-term outcomes of PCI versus CABG in patients with diabetes. METHODS: Clinical and administrative databases in Ontario, Canada were linked to obtain records of all patients with diabetes with angiographic evidence of 2- or 3-vessel CAD who were treated with either PCI or isolated CABG from 2008 to 2017. A 1:1 propensity score match was performed to account for baseline differences. All-cause mortality and the composite of myocardial infarction, repeat revascularization, stroke, or death (termed major cardiovascular and cerebrovascular events [MACCEs]) were compared between the matched groups using a stratified log-rank test and Cox proportional hazards model. RESULTS: A total of 4,519 and 9,716 patients underwent PCI and CABG, respectively. Before matching, patients who underwent CABG were significantly younger (age 65.7 years vs. 68.3 years), were more likely to be men (78% vs. 73%) and had more severe CAD. Propensity score matching based on 23 baseline covariates yielded 4,301 well-balanced pairs. There was no difference in early mortality between PCI and CABG (2.4% vs. 2.3%; p = 0.721) after matching. The median and maximum follow-ups were 5.5 and 11.5 years, respectively. All-cause mortality (hazard ratio [HR]: 1.39; 95% CI: 1.28 to 1.51) and overall MACCEs (HR: 1.99; 95% CI: 1.86 to 2.12) were significantly higher with PCI compared with CABG. CONCLUSIONS: In patients with multivessel CAD and diabetes, CABG was associated with improved long-term mortality and freedom from MACCEs compared with PCI.
