BACKGROUND: The optimal duration of dual antiplatelet therapy (DAPT) for preventing delayed thromboembolic events (DTEs) remains unclear. We aimed to determine whether longer DAPT provides improved protection against delayed DTEs. METHODS: This retrospective cohort study included 507 stent-assisted coil embolization procedures using a single stent for unruptured intracranial aneurysms. We performed coarsened exact matching according to the duration of maintenance DAPT...

INTRODUCTION: Multiple jobholders (MJHs) have a higher risk of injury compared to single jobholders (SJHs), but it is unknown if return-to-work (RTW) after a work injury is affected by multiple jobholding. This study examined the association between multiple versus single jobholding and time to RTW for workers with a work-related musculoskeletal disorder (MSD). METHODS: We used administrative workers' compensation data to identify injured workers with an accepted MSD lost-time claim between 2010-2014 in British Columbia, Canada (n = 125,639 SJHs and 9,029 MJHs)...

OBJECTIVE: The majority of previous studies, including randomized controlled trials, have failed to provide sufficient evidence of superiority of endovascular aneurysm repair (EVAR) over open aortic repair (OAR) of ruptured abdominal aortic aneurysm (rAAA) while comparing mortality and complications. This is in part due to small study size, patient selection bias, scarce adjustment for essential variables, single insurance type, or selection of only older patients. This study aimed to provide real-world, contemporary, comprehensive, and robust evidence on mortality of EVAR vs OAR of rAAA...

Background: Military service is associated with smoking initiation, but U.S. veterans are also eligible for special social, financial, and healthcare benefits, which are associated with smoking cessation. A key public health question is how these offsetting pathways affect health disparities; we assessed the net effects of military service on later life pulmonary function among Korean War era veterans by childhood socio-economic status (cSES). Methods: Data came from U...

Insurance status has been shown to be a predictor of patient morbidity and mortality. The purpose of this study was to evaluate the effect of patient insurance status on the in-hospital complication rates following total knee arthroplasty. Data were obtained from the Nationwide Inpatient Sample (2004 through 2011). Patient demographics and comorbidities were analyzed and stratified by insurance type. Analysis was performed with a matched cohort comparing complication rates between patients with Medicare vs private insurance using the coarsened exact matching algorithm and multivariable logistic regression...

BACKGROUND: The U.S. Centers for Medicare and Medicaid Services (CMS) has defined a set of high-risk criteria to help define patients who are appropriate for carotid artery stenting (CAS), but these criteria have never been validated. We aimed to validate the CMS high-risk criteria in a nationally representative cohort of patients undergoing CAS and carotid endarterectomy (CEA). METHODS: All patients undergoing CAS (with embolic protection) or CEA in the Vascular Quality Initiative (VQI) database (2013-2016) were included...

Introduction: While females generally have better outcomes than males after traumatic injury, higher mortality has been shown to occur in females after intentional trauma in lower-income countries. However, gender differences in trauma outcomes in different countries have not been previously compared. We conducted a two-country comparative analysis to characterise gender differences in mortality for different mechanisms of injury. Methods: Two urban trauma databases were analysed from India and the USA for fall, motor vehicle collision (MVC) and assault patients between 2013 and 2015...

OBJECTIVE: The choice of antithrombotic agent used during percutaneous coronary intervention (PCI) is controversial. While earlier studies suggested a reduction in bleeding events with bivalirudin, these studies were confounded by the concomitant use of glycoprotein IIbIIIa inhibitors (GPI) in the heparin group. More recent studies have challenged the superiority of bivalirudin, pointing to an increased risk of stent thrombosis. Real-world data remains limited. METHODS: We queried our institutional catheterization laboratory database for all PCI cases performed between January 2003 and December 2012 using only heparin or only bivalirudin (no use of GPI)...

BACKGROUND: About 19% of the United States population lives in rural areas and is served by only 10% of the physician workforce. If this misdistribution represents a shortage of available surgeons, it is possible that outcomes for rural patients may suffer. The objective of this study was to explore differences in outcomes for emergency general surgery (EGS) conditions between rural and urban hospitals using a nationally representative sample. METHODS: Data from the 2007-2011 National Inpatient Sample were queried for adult patients (≥18 years) with a primary diagnosis consistent with an EGS condition, as defined by the American Association for the Surgery of Trauma...

BACKGROUND: Nonagenarians are under-represented in thrombolytic trials for acute ischemic stroke (AIS). The effectiveness of intravenous thrombolytics in nonagenarians in terms of safety and outcome is not well established. MATERIALS AND METHODS: We used a multinational registry to identify patients aged 90 years or older with good baseline functional status who presented with AIS. Differences in outcomes-disability level at 90 days, frequency of symptomatic intracerebral hemorrhage (sICH), and mortality-between patients who did and did not receive thrombolytics were assessed using multivariable logistic regression, adjusted for prespecified prognostic factors...
