RESUMO
BACKGROUND: Parents have reported increased symptoms of depression and anxiety during the COVID-19 pandemic. This study evaluated changes in mental health and addiction (MHA)-related health service use among mothers and other birthing parents during the COVID-19 pandemic. METHODS: We conducted a repeated cross-sectional study using health administrative data in Ontario, Canada. The population included all mothers and birthing parents (≥1 child aged 1-18, no children <1 to exclude postpartum parents) between January 2016 and December 2021. We compared rates of MHA-related outpatient physician visits, hospitalizations, and emergency department (ED) visits during COVID-19 (March 2020-December 2021) to pre-COVID-19 (pre-March 2020). RESULTS: MHA-related outpatient visit rates increased by 17â¯% (rate ratio (RR) 1.17, 95â¯% CI 1.16-1.18) during COVID-19. Monthly utilization rates remained higher than expected across the COVID-19 period. MHA-related ED visit rates remained lower than expected during COVID-19, while MHA-related hospitalization rates returned to expected levels by August 2020. The largest relative increases in MHA-related outpatient visits during COVID-19 were in mothers and other birthing parents living in higher income (RR 1.20, 95â¯% CI 1.19-1.22) or urban areas (RR 1.20, 95â¯% CI 1.18-1.21), with children aged 1-3â¯years (RR 1.23, 95â¯% CI 1.20-1.25) and with no history of MHA-related health service use (RR 1.20, 95â¯% CI 1.19-1.21). LIMITATIONS: This study only captured physician-delivered MHA-related health service use. CONCLUSIONS: The COVID-19 pandemic was associated with an increase in MHA-related outpatient visits among mothers and other birthing parents. These findings point to the need for improvements in mental health service access.
RESUMO
BACKGROUND: Coronavirus disease 2019 (COVID-19) vaccination has been associated with reduced outpatient antibiotic prescribing among older adults with laboratory-confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We assessed the impact of COVID-19 vaccination on outpatient antibiotic prescribing in the broader population of older adults, regardless of SARS-CoV-2 infection status. METHODS: We included adults aged ≥65 years who received their first, second, and/or third COVID-19 vaccine dose from December 2020 to December 2022. We used a self-controlled risk-interval design and included cases who received an antibiotic prescription 2-6 weeks before vaccination (pre-vaccination or control interval) or after vaccination (post-vaccination or risk interval). We used conditional logistic regression to estimate the odds of being prescribed (1) any antibiotic, (2) a typical "respiratory" infection antibiotic, or (3) a typical "urinary tract" infection antibiotic (negative control) in the post-vaccination interval versus the pre-vaccination interval. We accounted for temporal changes in antibiotic prescribing using background monthly antibiotic prescribing counts. RESULTS: 469 923 vaccine doses met inclusion criteria. The odds of receiving any antibiotic or a respiratory antibiotic prescription were lower in the post-vaccination versus pre-vaccination interval (aOR, .973; 95% CI, .968-.978; aOR, .961; 95% CI, .953-.968, respectively). There was no association between vaccination and urinary antibiotic prescriptions (aOR, .996; 95% CI, .987-1.006). Periods with high (>10%) versus low (<5%) SARS-CoV-2 test positivity demonstrated greater reductions in antibiotic prescribing (aOR, .875; 95% CI, .845-.905; aOR, .996; 95% CI, .989-1.003, respectively). CONCLUSIONS: COVID-19 vaccination was associated with reduced outpatient antibiotic prescribing in older adults, especially during periods of high SARS-CoV-2 circulation.

OBJECTIVE: To examine changes in the prescribing of end-of-life symptom management medications in long-term care (LTC) homes during the COVID-19 pandemic. DESIGN: Retrospective cohort study using routinely collected health administrative data in Ontario, Canada. SETTING AND PARTICIPANTS: We included all individuals who died in LTC homes between January 1, 2017, and March 31, 2021. We separated the study into 2 periods: before COVID-19 (January 1, 2017, to March 17, 2020) and during COVID-19 (March 18, 2020, to March 31, 2021). METHODS: For each LTC home, we measured the percentage of residents who died before and during COVID-19 who had a subcutaneous symptom management medication prescription in their last 14 days of life. We grouped LTC homes into quintiles based on their mean prescribing rates before COVID-19, and examined changes in prescribing during COVID-19 and COVID-19 outcomes across quintiles. RESULTS: We captured 75,438 LTC residents who died in Ontario's 626 LTC homes during the entire study period, with 19,522 (25.9%) dying during COVID-19. The mean prescribing rate during COVID-19 ranged from 46.9% to 79.4% between the lowest and highest prescribing quintiles. During COVID-19, the mean prescribing rate in the lowest prescribing quintile increased by 9.6% compared to before COVID-19. Compared to LTC homes in the highest prescribing quintile, homes in the lowest prescribing quintile experienced the highest proportion of COVID-19 outbreaks (73.4% vs 50.0%), the largest mean outbreak intensity (0.27 vs 0.09 cases/bed), the highest mean total days with a COVID-19 outbreak (72.7 vs 24.2 days), and the greatest proportion of decedents who were transferred and died outside of LTC (22.1% vs 8.6%). CONCLUSIONS AND IMPLICATIONS: LTC homes in Ontario had wide variations in the prescribing rates of end-of-life symptom management medications before and during COVID-19. Homes in the lower prescribing quintiles had more COVID-19 cases per bed and days spent in an outbreak.

BACKGROUND: Medications are often needed to manage distressing end-of-life symptoms (eg, pain, agitation). OBJECTIVES: In this study, we describe the variation in prescribing rates of symptom relief medications at the end of life among long-term care (LTC) decedents. We evaluate the extent these medications are prescribed in LTC homes and whether prescribing rates of end-of-life symptom management can be used as an indicator of quality end-of-life care. DESIGN: Retrospective cohort study using administrative health data. SETTING AND PARTICIPANTS: LTC decedents in all 626 publicly funded LTC homes in Ontario, Canada, between January 1, 2017, and March 17, 2020. METHODS: For each LTC home, we measured the percent of decedents who received 1+ prescription(s) for a subcutaneous end-of-life symptom management medication ("end-of-life medication") in their last 14 days of life. We then ranked LTC homes into quintiles based on prescribing rates. RESULTS: We identified 55,916 LTC residents who died in LTC. On average, two-thirds of decedents (64.7%) in LTC homes were prescribed at least 1 subcutaneous end-of-life medication in the last 2 weeks of life. Opioids were the most common prescribed medication (overall average prescribing rate of 62.7%). LTC homes in the lowest prescribing quintile had a mean of 37.3% of decedents prescribed an end-of-life medication, and the highest quintile mean was 82.5%. In addition, across these quintiles, the lowest prescribing quintile had a high average (30.3%) of LTC residents transferred out of LTC in the 14 days compared with the highest prescribing quintile (12.7%). CONCLUSIONS AND IMPLICATIONS: Across Ontario's LTC homes, there are large differences in prescribing rates for subcutaneous end-of-life symptom relief medications. Although future work may elucidate why the variability exists, this study provides evidence that administrative data can provide valuable insight into the systemic delivery of end-of-life care.

This study was designed to determine if feeding ß-hydroxy-ß-methylbutyrate (HMB) to pregnant mice would improve birth weight uniformity and growth performance of offspring. Dams (Agouti Avy) were assigned to one of four treatments: control (CON; n = 13), low-level HMB (LL; 3.5 mg/g; n = 14), high-level HMB (HL; 35 mg/g; n = 15), and low-level pulse dose fed from gestational days 6 to 10 (PUL; 3.5 mg/g; n = 14). Randomly selected dams (n = 27) were euthanized on gestational day 18 to collect placentae and pup weights. The remaining dams gave birth and lactated for 28 days. Dams only received HMB during gestation. Dietary HMB did not influence the performance of dams. Dietary treatment during gestation did not affect litter size or birth weight of pups. Variation was not different among treatments in terms of birth weight of offspring. Placental weights were not affected by treatments. Overall, growth performance of offspring after weaning was similar among all treatments. Body composition of offspring at 5 and 8 weeks of age was similar regardless of HMB treatment during gestation. In conclusion, dietary HMB supplementation in pregnant mice did not affect birth weight, variations in birth weight, or growth performance of offspring.
RESUMO
Background: It is widely accepted that there is a stepwise increase in the risk of acute ischemic stroke with chronic kidney disease (CKD). However, whether the risk of specific ischemic stroke subtypes varies with CKD remains unclear. Objective: To assess the association between ischemic stroke subtypes (cardioembolic, arterial, lacunar, and other) classified using the Trial of ORG 10172 in Acute Stroke Treatment (TOAST) and CKD stage. Design: retrospective cohort study. Setting: Ontario, Canada. Patients: A total of 17 434 adults with an acute ischemic stroke in Ontario, Canada between April 1, 2002 and March 31, 2013, with an estimated glomerular filtration rate (eGFR) measurement or receipt of maintenance dialysis captured in a stroke registry were included. Measurements: Kidney function categorized as an eGFR of ≥60, 30-59, <30 mL/min/1.73 m2, or maintenance dialysis. Ischemic stroke classified by TOAST included arterial, cardioembolic, lacunar, and other (dissection, prothrombotic state, cortical vein/sinus thrombosis, and vasculitis) types of strokes. Methods: Adjusted regression models. Results: In our cohort, 58.9% had an eGFR of ≥60, 34.7% an eGFR of 30-59, 6.0% an eGFR of <30 and 0.5% were on maintenance dialysis (mean age of 73 years; 48% women). Cardioembolic stroke was more common in patients with non-dialysis-dependant CKD (eGFR 30-59: 50.4%, adjusted odds ratio [OR] 1.20, 95% confidence interval [CI]: 1.02, 1.44; eGFR<30: 50.6%, OR 1.21, 95% CI: 1.02, 1.44), whereas lacunar stroke was less common (eGFR 30-59: 22.7% OR 0.85, 95% CI: 0.77, 0.93; eGFR <30: 0.73, 95% CI: 0.61, 0.88) compared with those with an eGFR ≥60. In stratified analyses by age and CKD, lacunar strokes were more frequent in those aged less than 65 years, whereas cardioembolic was higher in those aged 65 years and above. Limitations: TOAST classification was not captured for all patients. Conclusion: Non-dialysis CKD was associated with a higher risk of cardioembolic stroke, whereas an eGFR ≥60 mL/min/1.73 m2 was associated with a higher risk of lacunar stroke. Detailed stroke subtyping in CKD may therefore provide mechanistic insights and refocus treatment strategies in this high-risk population.
Contexte: Il est largement admis qu'il y a une augmentation progressive du risque d'accident vasculaire cérébral ischémique aigu en contexte d'insuffisance rénale chronique (IRC). On ignore cependant si le risque de certains sous-types particuliers d'AVC ischémiques varie en présence d'IRC. Objectif: Évaluer le lien entre le stade d'IRC et certains sous-types d'AVC ischémiques (cardioembolique, artériel, lacunaire et autres) classés selon l'essai TOAST (Trial of ORG 10172 in Acute Stroke Treatment). Type d'étude: Étude de cohorte retrospective. Cadre: Ontario (Canada). Sujets: Ont été inclus 17 434 adultes ayant subi un AVC ischémique aigu en Ontario (Canada) entre le 1er avril 2002 et le 31 mars 2013, et pour lesquels le registre d'AVC comportait une mesure du débit de filtration glomérulaire estimé (DFGe) ou une dialyze chronique. Mesures: La fonction rénale a été classée selon le DFGe (≥ 60 ml/min/1,73 m2 entre 30 et 59 ml/min/1,73 m2 <30 ml/min/1.73 m2) ou une dialyze chronique. Les types d'AVC ischémiques classés par l'essai TOAST comprenaient les AVC artériels, cardioemboliques, lacunaires et autres (dissection, état prothrombotique, thrombose de la veine/sinus cortical, vascularite). Méthodologie: Modèles de régression ajustés. Résultats: Dans notre cohorte (âge moyen de 73 ans; 48% de femmes), 58,9 % des patients avaient un DFGe ≥ 60 ml/min/1,73 m2; 34,7% avaient un DFGe entre 30 et 59 ml/min/1,73 m2; 6,0 % avaient un DFGe < 30 ml/min/1,73 m2 et 0,5 % des patients étaient en dialyze chronique En comparaison des patients ayant un DFGe ≥ 60 ml/min/1,73 m2, les AVC cardioemboliques étaient plus fréquents chez les patients atteints d'IRC sans dialyze (DFGe entre 30 et 59 ml/min/1,73 m2: 50,4%; rapport de cote corrigé [RCc] = 1,20; IC 95 % = 1,02-1,44DFGe < 30 ml/min/1,73 m2: 50,6 %; RCc = 1,21; IC95% = 1,02-1,44) alors que les AVC lacunaires étaient moins fréquents [DFGe entre 30 et 59 ml/min/1,73 m2: 22,7%; RCc = 0,85; IC 95% = 0,77-0,93DFGe < 30 ml/min/1,73 m2: RCc = 0,73; IC 95% = 0,61-0,88]. Dans les analyses stratifiées en fonction de l'âge et de l'IRC, les AVC lacunaires étaient plus fréquents chez les moins de 65 ans tandis que les AVC cardioemboliques étaient plus fréquents chez les plus de 65 ans. Limites: La classification TOAST n'était pas enregistrée pour tous les patients. Conclusion: L'IRC sans dialyze a été associée à un risque plus élevé d'AVC cardioembolique alors qu'un DFGe ≥ 60 ml/min/1.73 m2 a été associé à un risque plus élevé d'AVC lacunaire. Le sous-typage détaillé des AVC en contexte d'IRC pourrait donc fournir des informations mécanistiques et recentrer les stratégies de traitement dans cette population à haut risque.
RESUMO
Introduction An invitation to speak at grand rounds (GR) is considered an honor and an activity important for academic promotion. The aim of this study was to determine the representation of women among invited speakers at departmental GR and assess the impact of the COVID-19 pandemic on it. Methods We conducted a retrospective descriptive study on gender differences in all GR speakers between January 2019 and June 2021 at an academic health system in Western Massachusetts. We calculated the overall percentage of women presenters and compared it with the percentage of women faculty at our institution and nationally. To evaluate the impact of COVID-19 on this association, we calculated the absolute percentage difference between women and men speakers using the date of March 13, 2020, as the cut-off and conducted a sensitivity analysis using June 15, 2020, as the cut-off. Results During the study period, 46% (276/607) of GR speakers at our institution were women. This percentage reflected the percentage of the women faculty overall at our institution and was similar to women's representation among faculty nationally. Departments with high percentages of women faculty (Obstetrics and Gynecology, 76%; Pediatrics, 65%) had high percentages of women GR speakers (Obstetrics and Gynecology, 70%; Pediatrics, 51%; Psychiatry, 62%). COVID-19 did not appear to significantly influence gender representation among speakers. Conclusion At our institution, less than half of the GR speakers were women. However, this percentage appears to reflect the overall percentage of women faculty. Potential barriers and opportunities resulting from the COVID-19 pandemic did not appear to impact this finding.
RESUMO
BACKGROUND: Physician home visits are associated with better health outcomes, yet most patients near the end of life never receive such a visit. Our objectives were to describe the receipt of physician home visits during the last year of life after a referral to home care - an indication that the patient can no longer live independently - and to measure associations between patient characteristics and receipt of a home visit. METHODS: We conducted a retrospective cohort study using linked population-based health administrative databases housed at ICES. We identified adult (aged ≥ 18 yr) decedents in Ontario who died between Mar. 31, 2013, and Mar. 31, 2018, who were receiving primary care and were referred to publicly funded home care services. We described the provision of physician home visits, office visits and telephone management. We used multinomial logistic regression to calculate the odds of receiving home visits from a rostered primary care physician, controlling for referral during the last year of life, age, sex, income quintile, rurality, recent immigrant status, referral by rostered physician, referral during hospital stay, number of chronic conditions and disease trajectory based on the cause of death. RESULTS: Of the 58 753 decedents referred in their last year of life, 3125 (5.3%) received a home visit from their family physician. Patient characteristics associated with higher odds of receiving home visits compared to office-based or telephone-based care were being female (adjusted odds ratio [OR] 1.28, 95% confidence interval [CI] 1.21-1.35), being 85 years of age or older (adjusted OR 2.42, 95% CI 1.80-3.26) and living in a rural area (adjusted OR 1.09, 95% CI 1.00-1.18). Increased odds were associated with home care referrals by the patient's primary care physician (adjusted OR 1.49, 95% CI 1.39-1.58) and referrals occurring during a hospital stay (adjusted OR 1.20, 95% CI 1.13-1.28). INTERPRETATION: A small proportion of patients near the end of life received home-based physician care, and patient characteristics did not explain the low visit rates. Future work on system- and provider-level factors may be critical to improve access to home-based end-of-life primary care.

Background: Surgical aortic valve replacement (SAVR) is a key strategy for the treatment of aortic valve disease. However, studies have involved primarily male patients, and whether the benefits of this approach can be extrapolated to female patients is unclear. Methods: Clinical and administrative datasets for 12,207 patients undergoing isolated SAVR in Ontario from 2008 to 2019 were linked. Male and female patients were balanced using inverse probability treatment weighting. Mortality, endocarditis, and major hemorrhagic and thrombotic events, as well as 2 composite outcomes-major adverse cerebral and cardiovascular events (MACCE) and patient-derived adverse cardiovascular and noncardiovascular events (PACE)-and their component events, were compared in the weighted groups with a stratified log-rank test. Results: A total of 7485 male patients and 4722 female patients were included in the study. Median follow-up was 5.2 years in both sexes. All-cause mortality did not differ between sexes (hazard ratio [HR] 0.949 [95% confidence interval {CI} 0.851-1.059]). Male sex was associated with an increased risk of new-onset dialysis (HR 0.689 [95% CI 0.488-0.974]). Female sex was associated with a significantly increased risk of both new-onset heart failure (HR 1.211 [95% CI 1.051-1.394], P = 0.0081) and heart failure hospitalization (HR 1.200 [95% CI 1.036-1.390], P = 0.015). No statistically significant differences were seen in any of the other secondary outcomes between sexes. Conclusions: This population health study demonstrated that survival did not differ between male and female patients undergoing SAVR. Significant sex-related differences were found in the risk of heart failure and new-onset dialysis, but these findings should be considered exploratory and require further study.
Contexte: La chirurgie de remplacement valvulaire aortique est une stratégie importante dans le traitement de la valvulopathie aortique. Cependant, les études ont été menées principalement auprès de patients masculins, et il est difficile d'affirmer si les avantages de cette approche peuvent être extrapolés aux patientes. Méthodologie: Les ensembles de données cliniques et administratives de 12 207 patients ayant subi uniquement une chirurgie de remplacement valvulaire aortique en Ontario entre 2008 et 2019 ont été regroupés. Les groupes de patients hommes et femmes ont été équilibrés à l'aide d'une pondération par probabilité inverse du traitement. La mortalité, l'endocardite et les événements hémorragiques et thrombotiques majeurs en plus de deux critères composés les événements cérébrovasculaires et cardiovasculaires indésirables majeurs et les événements cardiovasculaires et non cardiovasculaires indésirables rapportés par les patients et leurs événements constituants ont été comparés dans les groupes pondérés à l'aide d'un test logarithmique par rangs stratifié. Résultats: Au total, 7485 hommes et 4722 femmes ont été inclus dans l'étude. La durée médiane du suivi était de 5,2 ans chez les femmes comme chez les hommes. La mortalité toutes causes confondues ne différait pas entre les sexes (rapport de risques instantanés [RRI] : 0,949, intervalle de confiance [IC] à 95 % : 0,851 à 1,059). Le sexe masculin était associé à un risque accru d'instauration d'une dialyse (RRI : 0,689; IC à 95 % : 0,488 à 0,974). Le sexe féminin était associé à une augmentation significative du risque d'insuffisance cardiaque inaugurale (RRI : 1,211; IC à 95 % : 1,051 à 1,394; p = 0,0081) et d'hospitalisation pour une insuffisance cardiaque (RRI : 1,200; IC à 95 % : 1,036 à 1,390; p = 0,015). Aucune différence statistiquement significative n'a été notée entre les sexes pour les autres critères secondaires. Conclusions: Cette étude en santé des populations a montré que la survie chez les personnes subissant une chirurgie de remplacement valvulaire aortique ne diffère pas entre les hommes et les femmes. Des différences significatives fondées sur le sexe ont été notées dans le risque d'insuffisance cardiaque et de l'instauration d'une dialyse, mais ces constats doivent être considérés comme exploratoires et faire l'objet d'autres études.
RESUMO
BACKGROUND: Antibiotics are frequently prescribed unnecessarily in outpatients with coronavirus disease 2019 (COVID-19). We sought to evaluate factors associated with antibiotic prescribing in outpatients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. METHODS: We performed a population-wide cohort study of outpatients aged ≥66 years with polymerase chain reaction-confirmed SARS-CoV-2 from 1 January 2020 to 31 December 2021 in Ontario, Canada. We determined rates of antibiotic prescribing within 1 week before (prediagnosis) and 1 week after (postdiagnosis) reporting of the positive SARS-CoV-2 result, compared to a self-controlled period (baseline). We evaluated predictors of prescribing, including a primary-series COVID-19 vaccination, in univariate and multivariable analyses. RESULTS: We identified 13 529 eligible nursing home residents and 50 885 eligible community-dwelling adults with SARS-CoV-2 infection. Of the nursing home and community residents, 3020 (22%) and 6372 (13%), respectively, received at least 1 antibiotic prescription within 1 week of a SARS-CoV-2 positive result. Antibiotic prescribing in nursing home and community residents occurred, respectively, at 15.0 and 10.5 prescriptions per 1000 person-days prediagnosis and 20.9 and 9.8 per 1000 person-days postdiagnosis, higher than the baseline rates of 4.3 and 2.5 prescriptions per 1000 person-days. COVID-19 vaccination was associated with reduced prescribing in nursing home and community residents, with adjusted postdiagnosis incidence rate ratios (95% confidence interval) of 0.7 (0.4-1) and 0.3 (0.3-0.4), respectively. CONCLUSIONS: Antibiotic prescribing was high and with little or no decline following SARS-CoV-2 diagnosis but was reduced in COVID-19-vaccinated individuals, highlighting the importance of vaccination and antibiotic stewardship in older adults with COVID-19.

Importance: Eating disorders lead to increased mortality and reduced quality of life. While the acute presentations of eating disorders frequently involve electrolyte abnormalities, it remains unknown whether electrolyte abnormalities may precede the future diagnosis of an eating disorder. Objective: To determine whether outpatient electrolyte abnormalities are associated with the future diagnosis of an eating disorder. Design, Setting, and Participants: This population-level case-control study used provincial administrative health data for residents of Ontario, Canada aged 13 years or older from 2008 to 2020. Individuals without an eating disorder (controls) were matched 4:1 to individuals diagnosed with an incident eating disorder (cases) based on age and sex. Both groups had outpatient electrolyte measurements between 3 years and 30 days prior to index. Index was defined as the date of an eating disorder diagnosis in any inpatient or outpatient clinical setting for cases. Controls were assigned a pseudo-index date according to the distribution of index dates in the case population. Individuals with any prior eating disorder diagnosis were excluded. The data analyzed was from January 1, 2008, through June 30, 2020. Exposures: Any electrolyte abnormality, defined as abnormal test results for a composite of hypokalemia, hyperkalemia, hyponatremia, hypernatremia, hypomagnesemia, hypophosphatemia, metabolic acidosis, or metabolic alkalosis. Outcomes and Measures: Eating disorder diagnosis including anorexia nervosa, bulimia nervosa, and eating disorder not otherwise specified. Results: A total 6970 eligible Ontario residents with an eating disorder (mean [SD] age, 28 (19) years; 6075 [87.2%] female, 895 [12.8%] male) were matched with 27â¯878 age- and sex-matched residents without an eating disorder diagnosis (mean [SD] age, 28 [19] years; 24â¯300 [87.2%] female, 3578 [12.8%] male). Overall, 18.4% of individuals with an eating disorder had a preceding electrolyte abnormality vs 7.5% of individuals without an eating disorder (adjusted odds ratio [aOR], 2.12; [95% CI, 1.86-2.41]). The median (IQR) time from the earliest electrolyte abnormality to eating disorder diagnosis was 386 (157-716) days. Specific electrolyte abnormalities associated with a higher risk of an eating disorder were: hypokalemia (aOR, 1.98; 95% CI, 1.70-2.32), hyperkalemia (aOR, 1.97; 95% CI, 1.48-2.62), hyponatremia (aOR, 5.26; 95% CI, 3.32-8.31), hypernatremia (aOR, 3.09; 95% CI, 1.01-9.51), hypophosphatemia (aOR, 2.83; 95% CI, 1.82-4.40), and metabolic alkalosis (aOR, 2.60; 95% CI, 1.63-4.15). Conclusions and Relevance: In this case-control study, individuals with an eating disorder were associated with a preceding outpatient electrolyte abnormality compared with matched controls. Otherwise unexplained electrolyte abnormalities may serve to identify individuals who may benefit from screening for an underlying eating disorder.

Importance: Tamoxifen is commonly used as adjuvant therapy in breast cancer and is proposed to interfere with cytochrome P450 enzyme and P-glycoprotein pathways. Concurrent use with direct oral anticoagulants (DOACs) poses the threat of a potentially dangerous drug-drug interaction by leading to an increase in hemorrhage risk. Objective: To assess the risk of hemorrhage in patients with breast cancer coprescribed a DOAC and tamoxifen compared with a DOAC and an aromatase inhibitor (AI). Design, Setting, and Participants: This population-based, retrospective cohort study was conducted among adults aged 66 years or older who were prescribed tamoxifen (compared with an AI) concurrently with a DOAC in Ontario, Canada, between June 23, 2009, and November 30, 2020, and followed up until December 31, 2020. Interventions: Concurrent prescription of a DOAC and tamoxifen compared with a DOAC and an AI. Main Outcomes and Measures: The primary outcome was major hemorrhage requiring an emergency department visit or hospitalization after prescription. Overlap weighted Cox proportional hazards models, accounting for multiple covariates, were used to assess the association between hemorrhage and tamoxifen or AI use with a DOAC. Results: Among a total of 4753 patients (4679 [98.4%] women; mean [SD] age, 77.4 [7.4] years), 1179 (24.8%) were prescribed tamoxifen, and 3574 (75.2%) were prescribed an AI. Rivaroxaban (2530 [53.2%]) and apixaban (1665 [35.0%]) were the most frequently used DOACs. Patients taking AIs were younger than patients taking tamoxifen (mean [SD] age, 77.1 [7.3] vs 78.3 [7.6] years), with higher Charlson Comorbidity Index (mean [SD], 1.8 [2.4] vs 1.5 [2.2]) and more advanced cancer stage (stages III and IV, 569 [15.9%] vs 127 [10.8%]). During a median follow-up of 166 days (IQR, 111-527 days), tamoxifen was not associated with a higher risk of major hemorrhage (29 of 1179 [2.5%]) compared with an AI (119 of 3574 [3.3%]) when combined with a DOAC (absolute risk difference, -0.8%; weighted hazard ratio, 0.68 [95% CI, 0.44-1.06]). These results were similar in additional analyses using a more liberal definition of hemorrhage, accounting for kidney function, limiting follow-up to 90 days, stratifying by incident and prevalent DOAC users, and accounting for cancer duration and the competing risk of death. Conclusions and Relevance: In this cohort study, findings suggest that among DOAC users, the concurrent use of tamoxifen was not associated with a higher risk of hemorrhage compared with the concurrent use of an AI. These findings should directly inform prescribers regarding the apparent safety of concurrent DOAC and tamoxifen use.

BACKGROUND: Spontaneous coronary artery dissection (SCAD) is a cause of acute coronary syndrome that predominantly affects women. Its pathophysiology remains unclear but connective tissue disorders (CTD) and other vasculopathies have been observed in many SCAD patients. A genetic component for SCAD is increasingly appreciated, although few genes have been robustly implicated. We sought to clarify the genetic cause of SCAD using targeted and genome-wide methods in a cohort of sporadic cases to identify both common and rare disease-associated variants. METHODS: A cohort of 91 unrelated sporadic SCAD cases was investigated for rare, deleterious variants in genes associated with either SCAD or CTD, while new candidate genes were sought using rare variant collapsing analysis and identification of novel loss-of-function variants in genes intolerant to such variation. Finally, 2 SCAD polygenic risk scores were applied to assess the contribution of common variants. RESULTS: We identified 10 cases with at least one rare, likely disease-causing variant in CTD-associated genes, although only one had a CTD phenotype. No genes were significantly associated with SCAD from genome-wide collapsing analysis, however, enrichment for TGF (transforming growth factor)-ß signaling pathway genes was found with analysis of 24 genes harboring novel loss-of-function variants. Both polygenic risk scores demonstrated that sporadic SCAD cases have a significantly elevated genetic SCAD risk compared with controls. CONCLUSIONS: SCAD shares some genetic overlap with CTD, even in the absence of any major CTD phenotype. Consistent with a complex genetic architecture, SCAD patients also have a higher burden of common variants than controls.

INTRODUCTION: Approximately, one in ten infants is born preterm or requires hospitalization at birth. These complications at birth have long-term consequences that can extend into childhood and adulthood. Timely detection of developmental delay through surveillance could enable tailored support for these babies and their families. However, the possibilities for follow-up are limited, especially in middle- and low-income countries, and the tools to do so are either not available or too expensive. A standardized and core set of outcomes for neonates, with feasible tools for evaluation and follow-up, could result in improving quality, enhance shared decision-making, and enable global benchmarking. METHODS: The International Consortium for Health Outcomes Measurement (ICHOM) convened an international working group, which was comprised of 14 health-care professionals (HCP) and 6 patient representatives in the field of neonatal care. An outcome set was developed using a three-round modified Delphi process, and it was endorsed through a patient representative-validation survey and an HCP survey. RESULTS: A literature review revealed 1,076 articles and 26 registries which were screened for meaningful outcomes, patient-reported outcome measures, clinical measures, and case mix variables. This resulted in a neonatal set with 21 core outcomes covering three domains (physical, social, and mental functioning) and 14 tools to assess these outcomes at three timepoints. DISCUSSION: This set can be implemented globally and it will allow comparison of outcomes across different settings and countries. The transparent consensus-driven development process which involved stakeholders and professionals from all over the world ensures global relevance.

IMPORTANCE: Concussion may exacerbate existing mental health issues. Little evidence exists on whether concussion is associated with the onset of new psychopathologies or long-term mental health problems. OBJECTIVE: To investigate associations between concussion and risk of subsequent mental health issues, psychiatric hospitalizations, self-harm, or suicides. DESIGN, SETTING, AND PARTICIPANTS: This population-based retrospective cohort study including children and youths aged 5 to 18 years with a concussion or orthopedic injury incurred between April 1, 2010, and March 31, 2020, in Ontario, Canada. Participants had no previous mental health visit in the year before the index event for cohort entry and no prior concussion or traumatic brain injury 5 years before the index visit. Data were collected from provincewide health administrative databases. Participants with concussion were included in the exposed cohort, and those with an orthopedic injury were included in the comparison cohort; these groups were matched 1:2, respectively, on age and sex. EXPOSURES: Concussion or orthopedic injury. MAIN OUTCOMES AND MEASURES: The primary outcome was mental health problems, such as psychopathologies and psychiatric disorders, identified from health care visits in emergency departments, hospitalizations, or primary care settings. Secondary outcomes were psychiatric hospitalizations, self-harm health care visits, and death by suicide (identified in health care or vital statistics databases). RESULTS: A total of 152â¯321 children and youths with concussion (median [IQR] age, 13 [10-16] years; 86â¯423 [56.7%] male) and 296â¯482 children and youths with orthopedic injury (median [IQR] age, 13 [10-16] years; 171â¯563 [57.9%] male) were matched by age and sex. The incidence rates of any mental health problem were 11â¯141 per 100â¯000 person-years (exposed group) and 7960 per 100â¯000 person-years (unexposed group); with a difference of 3181 (95% CI, 3073-3291) per 100â¯000 person-years. The exposed group had an increased risk of developing a mental health issue (adjusted hazard ratio [aHR], 1.39; 95% CI, 1.37-1.40), self-harm (aHR, 1.49; 95% CI, 1.42-1.56), and psychiatric hospitalization (aHR, 1.47; 95% CI, 1.41-1.53) after a concussion. There was no statistically significant difference in death by suicide between exposed and unexposed groups (HR, 1.54; 95% CI, 0.90-2.61). CONCLUSIONS AND RELEVANCE: Among children and youths aged 5 to 18 years, concussion was associated with an increased risk of mental health issues, psychiatric hospitalization, and self-harm compared with children and youths with an orthopedic injury.

Background: For hospitalized patients with palliative care needs, there is little evidence on whether postdischarge outcomes differ if inpatient palliative care was delivered by a palliative care specialist or nonspecialist/generalist. Objective: To evaluate relationships between inpatient palliative care involvement and physician-delivered palliative care in the community after hospital discharge among individuals with limited life expectancy. Design: Population-based retrospective cohort study using administrative health data. Settings/Subjects: Adults with a predicted median survival of six months or less admitted to acute care hospitals in Ontario, Canada, between April 1, 2013, and March 31, 2017, and discharged to the community. Measurements: Inpatient palliative care involvement was classified as high (e.g., palliative care unit), medium (e.g., palliative care specialist consult), low (e.g., generalist-delivered palliative care), or none. Community palliative care included outpatient and home and clinic visits three weeks postdischarge. Results: Among 3660 hospitalized adults, 82 (2.2%) received inpatient palliative care with high level of involvement, 462 (12.6%) with medium level of involvement, 525 (14.3%) with low level of involvement, and 2591 (70.8%) had no inpatient palliative care. Patients who received inpatient palliative care were more likely to receive community palliative care after discharge than those who received no inpatient palliative care. These associations were stronger among patients who received high/medium palliative care involvement than patients who received low palliative care involvement. Conclusions: Inpatient palliative care, including that delivered by generalists, is associated with an increased likelihood of community palliative care after discharge. Increased inpatient generalist palliative care may help support patients' palliative care needs.

INTRODUCTION: The British Orthopaedic Association (BOA) guidelines in managing supracondylar humerus fractures in children, outline indications for urgent fixation of these fractures. We present our data from a regional paediatric trauma centre before and after implementing a change in practice as per these guidelines. MATERIALS AND METHODS: Retrospective clinical audit against BOA guidelines. Radiographs, admission clerking notes, operation notes, and clinic letters were all reviewed. We included all displaced supracondylar fractures of the extension type (Gartland Types 2b and 3). The first audit cycle occurred in 2017, subsequent cycles in 2018 & 2019. RESULTS: 172 patients reviewed across the three audit stages. In the first audit, almost quarter of patients were operated on in the same night without clear indication as per the guidelines. This dropped down to 7% after a change of practice in 2019. Rate of conversion to open reduction and nerve complications did not increase after delayed fixation. CONCLUSION: When there is no indication for same night operating out of hours, delaying treatment until the next day seems to be a safe way of treating these difficult fractures. Our data show that there is no increase in complications when these fractures are managed the next day.

From April 2022, current Deprivation of Liberty Safeguards (DoLS) will be replaced by Liberty Protection Safeguards (LPS). This review article outlines key information about these changes for patients, carers and healthcare professionals, for whom a deprivation of liberty may be relevant.Deprivation of liberty occurs within healthcare settings when someone's freedoms are limited in order to meet their care needs and lack capacity to consent to these arrangements. DoLS, enacted in 2009, ensured that patients deprived of liberties in care settings have similar rights to patients held under the Mental Health Act 1983. However, DoLS have been extensively criticised and considered unfit for purpose, therefore are being replaced by LPS.LPS intend to provide a more robust protection to a wider group of vulnerable people. This includes changes to patient age, transferability between a wider range of care settings, a reduced number of assessments for authorisation and less frequent reauthorisations.
RESUMO
BACKGROUND: The definition of population-specific outcomes is an essential precondition for the implementation of value-based health care. We developed a minimum standard outcome set for overall adult health (OAH) to facilitate the implementation of value-based health care in tracking, comparing, and improving overall health care outcomes of adults across multiple conditions, which would be of particular relevance for primary care and public health populations. METHODS: The International Consortium for Health Outcomes Measurement (ICHOM) convened an international panel (patients, clinicians, and topic experts). Following the development of a conceptual framework, a modified Delphi method (supported by public consultations) was implemented to identify, in sequence, the relevant domains, the best instruments for measuring them, the timing of measurement, and the relevant adjustment variables. FINDINGS: Outcomes were identified in relation to overall health status and the domains of physical, mental, and social health. Three instruments covering these domains were identified: PROMIS Scale v1.2-Global Health (10 items), WHO Wellbeing Index (5 items), and the WHO Disability Assessment Schedule 2.0 (12 items). Case-mix variables included a range of sociodemographic and biometric measures. Yearly measurement was proposed for all outcomes and most case-mix variables. INTERPRETATION: The ICHOM OAH Standard Set has been developed through consensus-based methods based on predefined criteria following high standards for the identification and selection of high-quality measures The involvements of a wide range of stakeholders supports the acceptability of the set, which is readily available for use and feasibility testing in clinical settings.

This study determined if meeting the Canadian 24-Hour Movement Guidelines recommendations are associated with all-cause mortality. Participants were 3471 adults from the 2005-2006 U.S. National Health and Nutrition Examination Survey followed for mortality over 11 years. They were classified as meeting or not meeting recommendations for sleep duration, sedentary behaviour, and moderate-to-vigorous physical activity (MVPA). A total of 63.8%, 35.3%, and 41.5% of participants met recommendations for sleep, sedentary behaviour, and physical activity while 12.3% met all 3 recommendations. The hazard ratio (HR) for all-cause mortality in participants meeting the recommendations relative to those not meeting the recommendations were 0.91 (0.72, 1.16) for sleep, 0.92 (0.61, 1.40) for sedentary behaviour, and 0.42 (0.24, 0.74) for MVPA. The HR for meeting none, any 1, any 2, and all 3 recommendations were 1.00, 0.86 (0.65, 1.14), 0.49 (0.28, 0.86), and 0.72 (0.34, 1.50). When the cut-point used to denote acceptable sedentary time was changed from ≤8 to ≤10 hours/day, the HR for meeting none, any 1, any 2, and all 3 recommendations were 1.00, 0.83 (0.59, 1.15), 0.57 (0.34, 0.96), and 0.43 (0.20, 0.93). These findings provide some support of the ability of the 24-hour Movement Guidelines to predict mortality risk. Novelty: The 24-Hour Movement Guidelines provide recommendations for sleep, sedentary behaviour, and physical activity. The findings of this study provide some support of the ability of these new guidelines to predict mortality risk.
