Local barrier dysfunction identified by confocal laser endomicroscopy predicts relapse in inflammatory bowel disease
2011
Objectives: Loss of intestinal barrier function plays an important role in the pathogenesis of inflammatory bowel disease (IBD). Shedding of intestinal epithelial cells is a potential cause of barrier loss during inflammation. The objectives of the study were (1) to determine whether cell shedding and barrier loss in humans can be detected by confocal endomicroscopy and (2) whether these parameters predict relapse of IBD. Methods: Confocal endomicroscopy was performed in IBD and control patients using intravenous fluorescein to determine the relationship between cell shedding and local barrier dysfunction. A grading system based on appearances at confocal endomicroscopy in humans was devise…
Estimating global injuries morbidity and mortality
2020
Background. While there is a long history of measuring death and disability from injuries, modern research methods must account for the wide spectrum of disability that can occur in an injury, and must provide estimates with sufficient demographic, geographical and temporal detail to be useful for policy makers. The Global Burden of Disease (GBD) 2017 study used methods to provide highly detailed estimates of global injury burden that meet these criteria. Methods. In this study, we report and discuss the methods used in GBD 2017 for injury morbidity and mortality burden estimation. In summary, these methods included estimating cause-specific mortality for every cause of injury, and then est…
Efficacy and safety of once-daily QVA149 compared with the free combination of once-daily tiotropium plus twice-daily formoterol in patients with mod…
2015
Background QVA149 is a once-daily (o.d.) inhaled dual bronchodilator containing a fixed-dose combination of the long-acting β2-agonist indacaterol and the long-acting muscarinic antagonist glycopyrronium for the treatment of COPD. The QUANTIFY study compared QVA149 with a free-dose bronchodilator combination of tiotropium plus formoterol (TIO+FOR) in improving health-related quality of life (HRQoL) of patients with COPD. Methods This multicentre, blinded, triple-dummy, parallel-group, non-inferiority study randomised patients aged ≥40 years with moderate-to-severe COPD (post-bronchodilator forced expiratory volume in 1 s (FEV1) ≥30% to <80% predicted) to QVA149 110/50 µg o.d. or TIO 18 µg o…
Is high-sensitivity troponin, alone or in combination with copeptin, sensitive enough for ruling out NSTEMI in very early presenters at admission? A …
2019
Objectives: Copeptin and high-sensitivity cardiac troponin (HS-cTn) assays improve the early detection of non-ST-segment elevation myocardial infarction (NSTEMI). Their sensitivities may, however, be reduced in very early presenters.Setting: We performed a post hoc analysis of three prospective studies that included patients who presented to the emergency department for chest pain onset (CPO) of less than 6 hours.Participants: 449 patients were included, in whom 12% had NSTEMI. CPO occurred 4 hours in 146 patients. The prevalence of NSTEMI was similar in all groups (9%, 13% and 12%, respectively, p=0.281).Measures: Diagnostic performances of HS-cTn and copeptin at presentation were examined…
Benefit of primary percutaneous coronary interventions in the elderly with ST segment elevation myocardial infarction
2020
Objective Primary percutaneous coronary intervention (P-PCI) has demonstrated its efficacy in patients with ST segment elevation myocardial infarction (STEMI). However, patients with STEMI >= 75 years receive less P-PCI than younger patients despite their higher in-hospital morbimortality. The objective of this analysis was to determine the effectiveness of P-PCI in patients with STEMI >= 75 years. Methods We included 979 patients with STEMI >= 75 years, from the ATencion HOspitalaria del Sindrome coronario study, a registry of 8142 consecutive patients with acute coronary syndrome admitted at 31 Spanish hospitals in 2014-2016. We calculated a propensity score (PS) for the indication of P-P…
Sex differences in mortality in stable patients undergoing vasodilator stress cardiovascular magnetic resonance
2021
Abstract Introduction The prognostic value and therapeutic implications of ischemia as derived from vasodilator stress cardiovascular magnetic resonance (CMR) could differ in men and women, but it has not been stablished. Purpose We assessed the influence of the ischemic burden as derived from CMR on the risk of death and the effect of revascularization across sex. Methods We evaluated 6,237 consecutive patients with known or suspected chronic coronary syndrome (CCS). Extensive ischemia was defined as &gt;5 segments with perfusion deficit. Multivariate Cox proportional hazard regression models were used. Results A total of 2,371 (38.0%) patients were women and 583 (9.3%) underwent CMR-r…
Objectively measured physical activity in Finnish employees: a cross-sectional study.
2014
Objectives: To objectively measure the amount of intensity-specific physical activity by gender and age with respect to body mass index (BMI) during workdays and days off among Finnish employees. Design: A cross-sectional study. Setting: Primary care occupational healthcare units. Participants: A sample of 9554 Finnish employees (4221 men and 5333 women; age range 18–65 years; BMI range 18.5–40 kg/m2) who participated in health assessments related to occupational health promotion. Main outcome measurements: The amount of moderate-to-vigorous (MVPA) and vigorous (VPA) physical activity (≥3 and ≥6 metabolic equivalents, respectively) was assessed by estimating the minuteto-minute oxygen consu…
Experiences of a non-clinical set of adolescents and young adults living with persistent pain:a qualitative metasynthesis
2021
PurposeAround 15%–30% of adolescents and young adults (AYAs) experience persistent or chronic pain. The purpose of this study was to synthesise evidence from qualitative primary studies on how AYAs in a non-clinical population experience living with persistent pain.MethodA qualitative metasynthesis guided by Sandelowski and Barroso’s guidelines was used. The databases Medline, Embase, Cinahl, PsycINFO, Mednar and ProQuest were searched for studies from 1 January 2005 to 15 February 2021. Inclusion criteria were AYAs aged 13–24 years with first-hand experience of living with persistent, recurrent or episodic non-clinical pain in any body site. Pain associated with a medical diagnosis, malign…
Global and regional burden of disease and injury in 2016 arising from occupational exposures: a systematic analysis for the Global Burden of Disease …
2020
ObjectivesThis study provides an overview of the influence of occupational risk factors on the global burden of disease as estimated by the occupational component of the Global Burden of Disease (GBD) 2016 study.MethodsThe GBD 2016 study estimated the burden in terms of deaths and disability-adjusted life years (DALYs) arising from the effects of occupational risk factors (carcinogens; asthmagens; particulate matter, gases and fumes (PMGF); secondhand smoke (SHS); noise; ergonomic risk factors for low back pain; risk factors for injury). A population attributable fraction (PAF) approach was used for most risk factors.ResultsIn 2016, globally, an estimated 1.53 (95% uncertainty interval 1.39…
Genetic variants in a sodium-dependent vitamin C transporter gene and age-related cataract
2018
BACKGROUND: Cataract is a major health burden in many countries and a significant problem in India. While observational studies show lower cataract risk with increasing dietary or plasma vitamin C, randomised controlled trials of supplements have been negative. Genetic variants in vitamin C transporter proteins (SLC23A1), especially rs33972313, may provide evidence on a causal association of vitamin C with cataract. METHODS: We used data from a randomly selected population-based study in people aged 60 years and above in north and south India. Of 7518 sampled, 5428 (72%) were interviewed for socioeconomic and lifestyle factors, attended hospital for lens imaging and blood collection and wer…
