BACKGROUND: Patients with severely reduced left-ventricular ejection fraction carry a high risk of morbidity and mortality after cardiac surgery. Levosimendan can be used prophylactically in these patients having shown positive effects on short-term outcome. However, effects on long-term outcome and patient subgroups benefiting the most are unknown. We aim to address these topics with real-life data from our clinical practice. METHODS: Two hundred eigthy eight patients with preoperative LVEF ≤ 35% underwent cardiac surgery with cardiopulmonary bypass between 2009 and 2013...

BACKGROUND: Despite a comprehensive ban on cultivation, manufacture, distribution, and sale of tobacco products since 2004, two nationwide surveys conducted in 2012 and 2013 reported high tobacco use in Bhutan. National Health Survey 2012 reported that 4 % of the population aged 15-75 years used smoked tobacco and about 48 % used smokeless tobacco. Similarly, Global Youth Tobacco Survey (GYTS) of Bhutan reported tobacco use prevalence of 30.3 % in 2013. However, factors associated with this high tobacco use were not systematically studied...

BACKGROUND: Reliable and comparable data on causes of death are crucial for public health analysis, but the usefulness of these data can be markedly diminished when the approach to coding is not standardized across territories and/or over time. Because the Russian system of producing information on causes of death is highly decentralized, there may be discrepancies in the coding practices employed across the country. In this study, we evaluate the uniformity of cause-of-death coding practices across Russian regions using an indirect method...

BACKGROUND: Arthritis is a gendered disease where women have a higher prevalence and more disability than men with arthritis of the same age. Health survey data is a major source of information for monitoring of the burden of arthritis. The validity of self-reported arthritis and the determinants of its accuracy among women have not been thoroughly studied. The objectives of this study were to: 1) examine the agreement between self-report diagnosed arthritis and musculoskeletal signs and symptoms in community-living older women; 2) estimate the sensitivity, specificity, and predictive values of self-reported arthritis; and 3) assess the factors associated with the disagreement...

Current biomarkers of renal disease in systemic vasculitis lack predictive value and are insensitive to early damage. To identify novel biomarkers of renal vasculitis flare, we analysed the longitudinal urinary metabolomic profile of a rat model of anti-neutrophil cytoplasmic antibody (ANCA) vasculitis. Wistar-Kyoto (WKY) rats were immunised with human myeloperoxidase (MPO). Urine was obtained at regular intervals for 181 days, after which relapse was induced by re-challenge with MPO. Urinary metabolites were assessed in an unbiased fashion using nuclear magnetic resonance (NMR) spectroscopy, and analysed using partial least squares discriminant analysis (PLS-DA) and partial least squares regression (PLS-R)...

Atrial fibrillation (AF) is the most common supraventricular arrhythmia following ST elevation myocardial infarction (STEMI). Oxidative stress and inflammation may cause structural and electrical remodeling in the atria making these critical processes in the pathology of AF. In this study, we aimed to evaluate the association between total oxidative status (TOS), total antioxidative capacity (TAC) and high-sensitivity C-reactive protein (hs-CRP) in the development of AF in patients presenting with STEMI. This prospective cohort study consisted of 346 patients with STEMI...

OBJECTIVE: To examine the importance of distinguishing between primary and secondary racial identification in analyzing health disparities in a multiracial population. METHODS: A cross-sectional analysis of 2012 Hawaii Behavioral Risk Factor Surveillance System (H-BRFSS). As part of the survey, respondents were asked to identify all their races, and then which race they considered to be their primary race. We introduce two analytic approaches to investigate the association between multiracial status and general health: (1) including two separate dichotomous variables for each racial group (primary and secondary race; for example, 'primary Native Hawaiian' and, separately, 'secondary Native Hawaiian'), and (2) including one combined variable for anyone choosing a particular racial group, whether as primary or secondary race ('combined race'; e...

OBJECTIVES/HYPOTHESIS: HPV-positive oropharyngeal squamous cell carcinoma has a more favorable prognosis when compared to HPV-negative disease, regardless of the presence of nodal metastases. However, the importance of contralateral neck treatment based on HPV status has not been well studied. Given the historically poor prognostic implications of cervical nodal metastases, this study sought to elucidate the relationship between HPV status and contralateral/bilateral nodal metastasis in patients with oropharyngeal squamous cell carcinoma...

BACKGROUND: There is growing interest in value-based health care in the United States. Statistical analysis of large databases can inform us of the factors associated with and the probability of adverse events and unplanned readmissions that diminish quality and add expense. For example, increased operating time and high blood urea nitrogen (BUN) are associated with adverse events, whereas patients on antihypertensive medications were more likely to have an unplanned readmission. Many surgeons rely on their knowledge and intuition when assessing the risk of a procedure...

The family with sequence similarity 83, member D (FAM83D) gene is upregulated in hepatocellular carcinoma and ovarian cancer, and its overexpression has been reported to positively correlate with tumor progression. However, the clinical significance and biological function of FAM83D in lung adenocarcinoma has not been investigated. We determined the expression profile and clinical significance of FAM83D using The Cancer Genome Atlas (TCGA) and immunohistochemistry (IHC) analysis. Considerable upregulation of FAM83D was observed in LUAD tissues compared with adjacent normal tissues, and its overexpression was significantly associated with more advanced clinicopathological characteristics...

CarboxypeptidaseA4 (CPA4) is a zinc-containing exopeptidases, and its aberrant expression has been implicated in cancer development and progression. However, few studies have investigated the association between CPA4 over-expression and clinical significance in gastric cancer (GC). In this study, we employed immunohistochemistry to evaluate the expression of CPA4 in gastric cancer tissues, and found that elevated CPA4 expression was detected in 64% (n=100) of primary GCs, but was weak or no staining in the normal mucosa...
