Introduction: The primary objective of this study was to determine the incidence of clinically significant traumatic intracranial haemorrhage (T-ICH) following minor head trauma in older adults. Secondary objective was to investigate the impact of anticoagulant and antiplatelet therapies on T-ICH incidence. Methods: This retrospective cohort study extracted data from electronic patient records. The cohort consisted of patients presenting after a fall and/or head injury and presented to one of five ED between 1st March 2010 and 31st July 2017. Inclusion criteria were age ≥ 65 years old and a minor head trauma defined as an impact to the head without fulfilling criteria for traumatic brain injury. Results: From the 1,000 electronic medical records evaluated, 311 cases were included. The mean age was 80.1 (SD 7.9) years. One hundred and eighty-nine (189) patients (60.8%) were on an anticoagulant (n = 69), antiplatelet (n = 130) or both (n = 16). Twenty patients (6.4%) developed a clinically significant T-ICH. Anticoagulation and/or antiplatelets therapies were not associated with an increased risk of clinically significant T-ICH in this cohort (Odds ratio (OR) 2.7, 95% CI 0.9-8.3). Conclusion: In this cohort of older adults presenting to the ED following minor head trauma, the incidence of clinically significant T-ICH was 6.4%.

Background: Prior atherosclerotic cardiovascular disease (ASCVD), including coronary heart disease (CHD) and peripheral artery disease (PAD), are common among patients with stroke, a known risk factor for dementia. However, whether these conditions further increase the risk of post-stroke dementia remains uncertain. Objective: To examine whether prior ASCVD is associated with increased risk of dementia among stroke patients. Methods: A retrospective cohort study was conducted using the Clinical Practice Research Datalink with linkage to hospital data. Patients with first-ever stroke between 2006 and 2017 were followed up to 10 years. We used multi-variable Cox regression models to examine the associations of prior ASCVD with dementia and the impact of prior ASCVD onset and duration. Results: Among 63,959 patients, 7,265 cases (11.4%) developed post-stroke dementia during a median of 3.6-year follow-up. The hazard ratio (HR) of dementia adjusted for demographics and lifestyle was 1.18 (95% CI: 1.12–1.25) for ASCVD, 1.16 (1.10–1.23) for CHD, and 1.25 (1.13–1.37) for PAD. The HRs additionally adjusted for multimorbidity and medications were 1.07 (1.00–1.13), 1.04 (0.98–1.11), and 1.11 (1.00–1.22), respectively. Based on the fully adjusted estimates, there was no linear relationship between the age of ASCVD onset and post-stroke dementia (all p-trend >0.05). The adjusted risk of dementia was not increased with the duration of pre-stroke ASCVD (all p-trend >0.05). Conclusion: Stroke patients with prior ASCVD are more likely to develop subsequent dementia. After full adjustment for confounding, however, the risk of post-stroke dementia is attenuated, with only a slight increase with prior ASCVD.

Abstract Background Managing children with minor head trauma remains challenging for physicians who evaluate for the need for computed tomography (CT) imaging for clinically important traumatic brain injury (ciTBI) identification. The Pediatric Emergency Care Applied Research Network (PECARN) prediction rules were adopted in our pediatric emergency department (PED) in December 2013 to identify children at low risk for ciTBI. This study aimed to evaluate this implementation’s impact on CT rates and clinical outcomes. Methods Retrospective cohort study on pediatric patients with head trauma presenting to the PED of the American University of Beirut Medical Center in Lebanon. Participants were divided into pre- (December 2012 to December 2013) and post-PECARN (January 2014 to December 2016) groups. Patients were further divided into < 2 and ≥ 2 years and stratified into groups of low, intermediate and high risk for ciTBI. Bivariate analysis was conducted to determine differences between both groups. Results We included 1362 children of which 425 (31.2%) presented pre- and 937 (68.8%) presented post-PECARN rules implementation with 1090 (80.0%) of low, 214 (15.7%) of intermediate and 58 (4.3%) of high risk for ciTBI. CTs were ordered on 92 (21.6%) pre- versus 174 (18.6%) patients post-PECARN (p = 0.18). Among patients < 2 years, CT rates significantly decreased from 25.2% (34/135) to 16.5% (51/309) post-PECARN (p = 0.03), and dropped in all risk groups but only significantly for low risk patients from 20.7% (24/116) to 11.4% (30/264) (p = 0.02). There was no significant decrease in CT rates in patients ≥2 years (20% pre (58/290) vs 19.6% post (123/628), p = 0.88). There was no increase in bounce back numbers, nor in admission rates or positive CT findings among bounce backs. Conclusions PECARN rules implementation did not significantly change the overall CT scan rate but reduced the CT scan rate in patients aged < 2 years at low risk of ciTBI. The implementation did not increase the number of missed ciTBI.

Abstract Purpose: To evaluate the association of hypertensive disorders of pregnancy with SARs-CoV-2 infection in pregnant women.Methods: We conducted a retrospective cohort study of all pregnant patients with positive SARs-CoV-2 molecular test at four participating hospitals located in a large metropolitan city and who delivered between February 1st and November 24th, 2020. Patients who tested positive during their pregnancy and delivered (index cases) were compared to the three subsequent deliveries of patients who tested negative (controls) at the same institution. We evaluated the impact of COVID-19 on the development of hypertensive disorders of pregnancy.Results: A total of 280 patients were included in the study: 70 patients who tested positive for Coronavirus Disease-2019 and 210 matched controls. Compared with pregnancies negative for SARS-CoV-2 infection, COVID-19 was associated with an increased risk of developing a hypertensive disorders of pregnancy (OR 3.68, 95% CI 1.67 -8.10). Overall rates of preeclampsia with severe features were significantly higher in patients with a COVID-19 diagnosis (18.6% vs 7.1%, p=0.006). Of COVID-19 positive patients, an early SARS-CoV-2 infection (prior to 32 week’s gestation) conferred a higher risk of hypertensive disorders in pregnancy (OR=6.29, CI 1.64-24.07; p=0.007). There was no difference in route of delivery, preterm birth, intrauterine growth restriction, intrauterine fetal demise, or pregnancy and fetal outcomes.Conclusion: COVID-19 is a risk factor for hypertensive disorders of pregnancy.Tweetable AbstractPatients who test positive for COVID-19 during their pregnancy are at increased risk of developing a hypertensive disorder of pregnancy compared to pregnant patients who test negative for COVID-19. Earlier SARs-CoV-2 infection results in increased risk of developing a hypertensive disorder. Furthermore, even patients who are asymptomatic but positive for SARs-CoV-2 during their pregnancy have a higher risk of developing a hypertensive disorder of pregnancy.

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.
