Non-alcoholic fatty liver disease and the development of nephrolithiasis: A cohort study.
2017
Background Non-alcoholic fatty liver disease (NAFLD), a hepatic manifestation or precursor of metabolic syndrome, may increase nephrolithiasis, a renal manifestation of insulin resistance, but the prospective association between NAFLD and incident nephrolithiasis has not been evaluated. We examined the association of NAFLD with the development of nephrolithiasis in a large cohort of Korean men and women. Methods We performed a cohort study of 208,578 Korean adults who underwent a health checkup examination between January 2002 and December 2014 and were followed-up annually or biennially through December 2014. NAFLD was defined as the presence of fatty liver in the absence of excessive alco…
Circulating neprilysin hypothesis: A new opportunity for sacubitril/valsartan in patients with heart failure and preserved ejection fraction?
2021
BackgroundCirculating Neprilysin (sNEP) has emerged as a potential prognostic biomarker in heart failure (HF). In PARAGON-HF benefit of sacubitril/valsartan was only observed in patients with left ventricular ejection fraction (LVEF) ≤57%. We aimed to assess the prognostic value of sNEP in outpatients with HF and LVEF >57%, in comparison with patients with LVEF ≤57%.MethodsConsecutive HF outpatients were included from May-2006 to February-2016. The primary endpoint was the composite of all-cause death or HF hospitalization and the main secondary endpoint was the composite of cardiovascular death or HF hospitalization. For the later competing risk methods were used.ResultssNEP was measure…
GDF-15 predicts cardiovascular events in acute chest pain patients
2017
Background Treatment of patients presenting with possible acute myocardial infarction (AMI) is based on timely diagnosis and proper risk stratification aided by biomarkers. We aimed at evaluating the predictive value of GDF-15 in patients presenting with symptoms suggestive of AMI. Methods Consecutive patients presenting with suspected AMI were enrolled in three study centers. Cardiovascular events were assessed during a follow-up period of 6 months with a combined endpoint of death or MI. Results From the 1818 enrolled patients (m/f = 1208/610), 413 (22.7%) had an acute MI and 63 patients reached the combined endpoint. Patients with MI and patients with adverse outcome had higher GDF-15 le…
Prognostic implications of arterial blood gases in acute decompensated heart failure
2010
The prognostic value of arterial blood gases (ABG) in patients with acute decompensated heart failure (ADHF) is not well-established. We therefore conducted the present study to determine the relationship between ABG on admission and long-term mortality in patients with ADHF.We studied 588 patients consecutively admitted to our department with ADHF. ABG and classical prognostic variables were determined at patients' arrival to the emergency department. The independent association among the main variables of ABG (pO2, pCO2 and pH) and mortality was assessed with Cox regression analysis.At a median follow-up of 23months, 221 deaths (37.6%) were registered. 308 (52.4%), 54 (9.2%) and 50 (8.5%)…
Correlates of mortality in elderly COPD patients: focus on health-related quality of life
2009
BACKGROUND AND OBJECTIVE: The Saint George Respiratory Questionnaire (SGRQ) is widely used as a measure of health-related quality of life (HRQL) in patients with COPD. This study tested whether the SGRQ predicts the survival of patients with COPD. METHODS: The study recruited 238 patients with COPD who were participants in the multicentre Salute Respiratoria nell'Anziano (Sa.R.A.) study. Patients' sociodemographic, clinical and functional characteristics were assessed and the association between the SGRQ and mortality, corrected for potential confounders, was estimated. RESULTS: The mean age of study participants was 72.6 years. Over the 5-year observation period there were 88 deaths. After…
Pooled safety analysis of the fixed-dose combination of indacaterol and glycopyrronium (QVA149), its monocomponents, and tiotropium versus placebo in…
2014
BACKGROUND: To further assess the safety profile of the fixed-dose combination of indacaterol and glycopyrronium (QVA149) and its monocomponents; we investigated the impact of individual patient-level factors and time by integrating the patient-level safety data from the QVA149 clinical programme with relevant information from the independent indacaterol and glycopyrronium safety databases.METHODS: Data from 11,404 patients with chronic obstructive pulmonary disease (COPD) were pooled from 14 clinical studies of QVA149, indacaterol and glycopyrronium of ≥3 month's duration with at least two of the treatment groups: QVA149 110/50 μg, glycopyrronium 50 μg, indacaterol 150 μg, placebo or tiotr…
Prognostic value of fragmented QRS on a 12-lead ECG in patients with acute myocardial infarction
2013
Abstract Objective To investigate the determinants and the prognostic value of fragmented QRS (fQRS) after AMI. Patients and methods Prospective cohort of 307 consecutive patients with AMI. Main outcomes measured MACE (death plus non-fatal recurrent MI), hospitalization for an episode of heart failure, ventricular arrhythmia (VT or VF) at two years follow-up. Results On the serial 12-lead ECG recorded during the in-hospital stay, 162 (53%) had no fQRS ( no fQRS group ). 145 (47%) presented an fQRS, which was persistent in 108 (34%) patients ( persistent fQRS group ) and transient in 37 (12%) patients ( transient fQRS group ). Patients with a fragmented QRS (transient or persistent) were old…
Development of chronic hypoventilation in amyotrophic lateral sclerosis patients
2006
SummaryEarly prediction of respiratory muscle involvement and chronic hypoventilation (CH) in amyotrophic lateral sclerosis (ALS) patients can help to plan mechanical ventilatory aids and palliative care interventions well before respiratory failure occurs. To describe the natural history of the progressive pulmonary dysfunction leading to CH, and to identify potential parameters associated with its development in ALS, we prospectively followed 38 ALS patients up to 26 months, starting from their first presentation at our Clinic. At study entry, median FVC was 87% (interquartile range: 72–104%) and declined by 10% after 6 months (range: 2–49%), showing a very high inter-patient variability.…
Alternative ways of expressing forced expiratory volume in the first second and long-term mortality in elderly patients with asthma
2013
Abstract Background Clinical and epidemiologic evidence on asthma in the elderly is scant. There is evidence that forced expiratory volume in the first second (FEV 1 ), a commonly used indicator of overall pulmonary function, might not be an independent predictor of 5-year mortality in elderly patients with asthma. Objective To investigate the association between FEV 1 expressed using 3 alternative methods and 5-, 10-, and 15-year mortality in a population of elderly patients with asthma. Methods Participants in the Salute Respiratoria nell' Anziano study were included. Asthma was diagnosed at baseline according to spirometric and clinical data. Vital status at 15 years was assessed using d…
Medical and psychosocial predictors of mechanical circulatory support device implantation and competing outcomes in the Waiting for a New Heart Study
2011
Background Medical and psychosocial factors are related to 1-year outcomes in the Waiting for a New Heart Study. With increased use of mechanical circulatory support devices (MCSD) over the course of the study, we can now evaluate these variables as predictors of MCSD in an extended follow-up. Methods Analyses focused on 313 MCSD-free patients (82% men; aged 53 ± 11 years) newly listed for heart transplantation (HTx). Variables assessed at time of listing included psychosocial risk (depression, social isolation), quality of life, waiting list stress, and medical risk (Heart Failure Survival Score, pulmonary capillary wedge pressure). Cumulative incidence functions and cause-specific Cox mod…
