Correction: Surgical approach and the impact of epidural analgesia on survival after esophagectomy for cancer: A population-based retrospective cohort study

Objective: To compare emergency department (ED) presentations and hospital admissions for urgent early pregnancy conditions in Victoria before and after the onset of COVID-19 lockdown on 31 March 2020. Design: Population-based retrospective cohort study Setting: Australian state of Victoria Population: Pregnant women presenting to emergency departments or admitted to hospital Methods: We obtained state-wide hospital separation data from the Victorian Emergency Minimum Dataset and the Victorian Admitted Episodes Dataset from January 1, 2018, to October 31, 2020. A linear prediction model based on the pre-COVID period was used to identify the impact of COVID restrictions. Main outcome measures: Monthly ED presentations for miscarriage and ectopic pregnancy, hospital admissions for termination of pregnancy, with subgroup analysis by region, socioeconomic status, disease acuity, hospital type. Results: There was an overall decline in monthly ED presentations and hospital admissions for early pregnancy conditions in metropolitan areas where lockdown restrictions were most stringent. Monthly ED presentations for miscarriage during the COVID period were consistently below predicted, with the nadir in April 2020 (790 observed vs 985 predicted, 95% CI 835-1135). Monthly admissions for termination of pregnancy were also below predicted throughout lockdown, with the nadir in August 2020 (893 observed vs 1116 predicted, 95% CI 905-1326). There was no increase in ED presentations for complications following abortion, ectopic or molar pregnancy during the COVID period. Conclusions: Fewer women in metropolitan Victoria utilized hospital-based care for early pregnancy conditions during the first seven months of the pandemic, without any observable increase in maternal morbidity.

Background Prescriptions for gastric acid–suppressive agents, including proton-pump inhibitors (PPIs) and histamine type-2 receptor antagonists (H2RAs), are rising. However, little data exist regarding their association with dementia in the Asian population. The objective of this study was thus to investigate the impact of the use of PPIs and H2RAs on the risk of dementia in an Asian population with upper gastrointestinal disease (UGID). Methods We conducted a population-based retrospective cohort study with a 10-year follow-up using data from 2000 to 2015 derived from Taiwan’s Longitudinal Health Insurance Database. We included 6711 patients with UGID receiving gastric acid–suppressive agents, 6711 patients with UGID not receiving agents, and 6711 patients without UGID or treatment thereof, all at least 20 years of age. Groups were matched for age, sex, and index date. The association between gastric acid–suppressive agent use and dementia was analyzed using a Cox proportional hazards regression model adjusted for potential confounders. Results The adjusted hazard ratio (aHR) of dementia for patients with UGID receiving gastric acid–suppressive agents compared with patients with UGID without gastric acid–suppressive agents was 1.470 (95% confidence interval [CI] 1.267–1.705, p < 0.001). Both PPIs and H2RAs increase the risk of dementia (PPIs: aHR 1.886 [95% CI 1.377–2.582], p < 0.001; H2RAs: aHR 1.357 [95% CI 1.098–1.678], p < 0.01), with PPIs exhibiting significantly greater risk (aHR 1.456 [95% CI 1.022–2.075], p < 0.05). Conclusions Our results demonstrate an increased risk of dementia in patients with UGID receiving gastric acid–suppressive agents, including PPIs and H2RAs, and the use of PPIs was associated with a significantly greater risk than H2RA use.

The Impact

Background: There is limited Canadian evidence on the impact of socio-environmental factors on psychosis risk. We sought to examine the relationship between area-level indicators of marginalization and the incidence of psychotic disorders in Ontario. Methods: We conducted a retrospective cohort study of all people aged 14 to 40 years living in Ontario in 1999 using health administrative data and identified incident cases of psychotic disorders over a 10-year follow-up period. Age-standardized incidence rates were estimated for census metropolitan areas (CMAs). Poisson regression models adjusting for age and sex were used to calculate incidence rate ratios (IRRs) based on CMA and area-level marginalization indices. Results: There is variation in the incidence of psychotic disorders across the CMAs. Our findings suggest a higher rate of psychotic disorders in areas with the highest levels of residential instability (IRR = 1.26, 95% confidence interval [CI], 1.18 to 1.35), material deprivation (IRR = 1.30, 95% CI, 1.16 to 1.45), ethnic concentration (IRR = 1.61, 95% CI, 1.38 to 1.89), and dependency (IRR = 1.35, 95% CI, 1.18 to 1.54) when compared to areas with the lowest levels of marginalization. Marginalization attenuates the risk in some CMAs. Conclusions: There is geographic variation in the incidence of psychotic disorders across the province of Ontario. Areas with greater levels of marginalization have a higher incidence of psychotic disorders, and marginalization attenuates the differences in risk across geographic location. With further study, replication, and the use of the most up-to-date data, a case may be made to consider social policy interventions as preventative measures and to direct services to areas with the highest risk. Future research should examine how marginalization may interact with other social factors including ethnicity and immigration.
