The Crown-Wearing Abbeys of Westminster, Winchester, and Gloucester in text and written record, c.1100-1170

This thesis offers the first dedicated study of each of the three crown-wearing abbeys of Westminster, Winchester, and Gloucester between c.1100 and 1170 across their records and creative writings. In doing so this study provides new insight into three important and politically symbolic abbeys. This was a period which witnessed both contested monarchy and a surge in new monasticism that challenged the primacy of pre-Conquest Benedictine abbeys such as these. This study provides new findings into these circumstances by showing how English monarchy interacted with these abbeys in a time when royalty itself was insecure. It also reconstructs the fates of three ancient communities within England's rapidly changing religious landscape. Finally, this thesis also analyses different types of texts produced at these abbeys in this period, including hagiography, forged charters, and cartulary. The original findings from each of these texts are compared and contextualised, providing further insight into these communities and how they responded to the challenges of their present. This thesis analyses each abbey and its writings in turn. The first chapter investigates Westminster Abbey. In the chapter's first section, charters are used to reconstruct the abbey's fortunes and activities across the period. With this context established, the second section investigates Osbert of Clare's Vita Eadwardi, and the third assesses the abbey's twelfth-century forged charters, a small corpus of which were also written by Osbert. In the fourth section of this chapter the findings from the different types of writing are considered together. A similar methodology is followed in the second chapter on Winchester Cathedral Priory, where the materials are again charters, and hagiography (in this case the anonymous Vita Birini, Vita Swithuni, and Miracula Swithuni, and a cartulary known as the Codex Wintoniensis. At Gloucester Abbey the writings are charters, forged charters, and Benedict of Gloucester's Vita Dubricii

Effect of a novel mindfulness curriculum on burnout during pediatric internship: A cluster randomized clinical trial

Importance: Mindfulness curricula can improve physician burnout, but implementation during residency presents challenges. Objective: To examine whether a novel mindfulness curriculum implemented in the first 6 months of internship reduces burnout. Design, setting, and participants: This pragmatic, multicenter, stratified cluster randomized clinical trial of a mindfulness curriculum randomized 340 pediatric interns to the intervention or control arm within program pairs generated based on program size and region. Fifteen US pediatric training programs participated from June 14, 2017, to February 28, 2019. Interventions: The intervention included 7 hour-long sessions of a monthly mindfulness curriculum (Mindfulness Intervention for New Interns) and a monthly mindfulness refresher implemented during internship. The active control arm included monthly 1-hour social lunches. Main outcomes and measures: The primary outcome was emotional exhaustion (EE) as measured by the Maslach Burnout Inventory 9-question EE subscale (range, 7-63; higher scores correspond to greater perceived burnout). Secondary outcomes were depersonalization, personal accomplishment, and burnout. The study assessed mindfulness with the Five Facet Mindfulness Questionnaire and empathy with the Interpersonal Reactivity Index subscales of perspective taking and empathetic concern. Surveys were implemented at baseline, month 6, and month 15. Results: Of the 365 interns invited to participate, 340 (93.2%; 255 [75.0%] female; 51 [15.0%] 30 years or older) completed surveys at baseline; 273 (74.8%) also participated at month 6 and 195 (53.4%) at month 15. Participants included 194 (57.1%) in the Mindfulness Intervention for New Interns and 146 (42.9%) in the control arm. Analyses were adjusted for baseline outcome measures. Both arms\u27 EE scores were higher at 6 and 15 months than at baseline, but EE did not significantly differ by arm in multivariable analyses (6 months: 35.4 vs 32.4; adjusted difference, 3.03; 95% CI, -0.14 to 6.21; 15 months: 33.8 vs 32.9; adjusted difference, 1.42; 95% CI, -2.42 to 5.27). None of the 6 secondary outcomes significantly differed by arm at month 6 or month 15. Conclusions and relevance: A novel mindfulness curriculum did not significantly affect EE, burnout, empathy, or mindfulness immediately or 9 months after curriculum implementation. These findings diverge from prior nonrandomized studies of mindfulness interventions, emphasizing the importance of rigorous study design and suggesting that additional study is needed to develop evidence-based methods to reduce trainee burnout

ADHD medications and risk of serious cardiovascular events in young and middle-aged adults

CONTEXT: More than 1.5 million US adults use stimulants and other medications labeled for treatment of attention-deficit/hyperactivity disorder (ADHD). These agents can increase heart rate and blood pressure, raising concerns about their cardiovascular safety. OBJECTIVE: To examine whether current use of medications prescribed primarily to treat ADHD is associated with increased risk of serious cardiovascular events in young and middle-aged adults. DESIGN, SETTING, AND PARTICIPANTS: Retrospective, population-based cohort study using electronic health care records from 4 study sites (OptumInsight Epidemiology, Tennessee Medicaid, Kaiser Permanente California, and the HMO Research Network), starting in 1986 at 1 site and ending in 2005 at all sites, with additional covariate assessment using 2007 survey data. Participants were adults aged 25 through 64 years with dispensed prescriptions for methylphenidate, amphetamine, or atomoxetine at baseline. Each medication user (n = 150,359) was matched to 2 nonusers on study site, birth year, sex, and calendar year (443,198 total users and nonusers). MAIN OUTCOME MEASURES: Serious cardiovascular events, including myocardial infarction (MI), sudden cardiac death (SCD), or stroke, with comparison between current or new users and remote users to account for potential healthy-user bias. RESULTS: During 806,182 person-years of follow-up (median, 1.3 years per person), 1357 cases of MI, 296 cases of SCD, and 575 cases of stroke occurred. There were 107,322 person-years of current use (median, 0.33 years), with a crude incidence per 1000 person-years of 1.34 (95% CI, 1.14-1.57) for MI, 0.30 (95% CI, 0.20-0.42) for SCD, and 0.56 (95% CI, 0.43-0.72) for stroke. The multivariable-adjusted rate ratio (RR) of serious cardiovascular events for current use vs nonuse of ADHD medications was 0.83 (95% CI, 0.72-0.96). Among new users of ADHD medications, the adjusted RR was 0.77 (95% CI, 0.63-0.94). The adjusted RR for current use vs remote use was 1.03 (95% CI, 0.86-1.24); for new use vs remote use, the adjusted RR was 1.02 (95% CI, 0.82-1.28); the upper limit of 1.28 corresponds to an additional 0.19 events per 1000 person-years at ages 25-44 years and 0.77 events per 1000 person-years at ages 45-64 years. CONCLUSIONS: Among young and middle-aged adults, current or new use of ADHD medications, compared with nonuse or remote use, was not associated with an increased risk of serious cardiovascular events. Apparent protective associations likely represent healthy-user bias

Age and computed tomography and invasive coronary angiography in stable chest pain: a prespecified secondary analysis of the discharge randomized clinical trial

Importance: The effectiveness and safety of computed tomography (CT) and invasive coronary angiography (ICA) in different age groups is unknown. Objective: To determine the association of age with outcomes of CT and ICA in patients with stable chest pain. Design, Setting, and Participants: The assessor-blinded Diagnostic Imaging Strategies for Patients With Stable Chest Pain and Intermediate Risk of Coronary Artery Disease (DISCHARGE) randomized clinical trial was conducted between October 2015 and April 2019 in 26 European centers. Patients referred for ICA with stable chest pain and an intermediate probability of obstructive coronary artery disease were analyzed in an intention-to-treat analysis. Data were analyzed from July 2022 to January 2023. Interventions: Patients were randomly assigned to a CT-first strategy or a direct-to-ICA strategy. Main Outcomes and Measures: MACE (ie, cardiovascular death, nonfatal myocardial infarction, or stroke) and major procedure-related complications. The primary prespecified outcome of this secondary analysis of age was major adverse cardiovascular events (MACE) at a median follow-up of 3.5 years. Results: Among 3561 patients (mean [SD] age, 60.1 [10.1] years; 2002 female [56.2%]), 2360 (66.3%) were younger than 65 years, 982 (27.6%) were between ages 65 to 75 years, and 219 (6.1%) were older than 75 years. The primary outcome was MACE at a median (IQR) follow-up of 3.5 (2.9-4.2) years for 3523 patients (99%). Modeling age as a continuous variable, age, and randomization group were not associated with MACE (hazard ratio, 1.02; 95% CI, 0.98-1.07; P for interaction = .31). Age and randomization group were associated with major procedure-related complications (odds ratio, 1.15; 95% CI, 1.05-1.27; P for interaction = .005), which were lower in younger patients. Conclusions and Relevance: Age did not modify the effect of randomization group on the primary outcome of MACE but did modify the effect on major procedure-related complications. Results suggest that CT was associated with a lower risk of major procedure-related complications in younger patients
