Dynamic angiopoietin-2 assessment predicts survival and chronic course in hospitalized patients with COVID-19

2021

Key Points Three-day change in angiopoietin-2 levels predicts COVID-19 in-hospital mortality, whereas the 10-day trend is associated with chronic lung disability. Angiopoietin-2 may play an important pathogenic role in patients with COVID-19, and it could be a target for new treatments.

Changes in Motor, Cognitive, and Behavioral Symptoms in Parkinson's Disease and Mild Cognitive Impairment During the COVID-19 Lockdown

2020

Objective: The effects of the COVID-19 lockdown on subjects with prodromal phases of dementia are unknown. The aim of this study was to evaluate the motor, cognitive, and behavioral changes during the COVID-19 lockdown in Italy in patients with Parkinson's disease (PD) with and without mild cognitive impairment (PD-MCI and PD-NC) and in patients with MCI not associated with PD (MCInoPD).Methods: A total of 34 patients with PD-NC, 31 PD-MCI, and 31 MCInoPD and their caregivers were interviewed 10 weeks after the COVID-19 lockdown in Italy, and changes in cognitive, behavioral, and motor symptoms were examined. Modified standardized scales, including the Neuropsychiatric Inventory (NPI) and t…

Obesity, an independent predictor of pre and postoperative tumor grading disagreement in endometrial cancer

2021

Abstract Introduction Obesity is a known independent risk factor for endometrial cancer (EC), and obese patients have a 4.7-fold increased risk compared to the general population to develop the neoplasm. To date, a general pre and postoperative tumor grading agreement from 53 % to 82 % is reported for endometrial analysis, and a consensus on which factors might influence the tumor grading discordance is still absent. Furthermore, although obesity alters the endometrial microenvironment, no studies investigated the role of obesity in the grading agreement of EC patients. This study aims to analyze the role of obesity in the pre and postoperative tumor grading agreement. Materials and methods…

Monofocal hepatocellular carcinoma: How much does size matter?

2020

Background & Aims: According to the Barcelona Clinic Liver Cancer (BCLC) staging system, monofocal hepatocellular carcinoma (HCC) is classified as early (BCLC A) irrespective of its size, even though controversies still exist regarding staging and treatment of large tumours. We aimed at evaluating the appropriate staging and treatment for large (>5 cm) monofocal (HCC). Methods: From the Italian Liver Cancer database, we selected 924 patients with small early monofocal HCC (2-5 cm; SEM-HCC), 163 patients with larger tumours (>5 cm; LEM-HCC) and 1048 intermediate stage patients (BCLC B). Results: LEM-HCC patients had a worse overall survival (OS) than SEM-HCC (31.0 vs 49.0 months; P…

Evaluation of the Complexity of Myocardial Activation During Ventricular Fibrillation. An Experimental Study

2013

A B S T R A C T Introduction and objectives: An experimental model is used to analyze the characteristics of ventricular fibrillation in situations of variable complexity, establishing relationships among the data produced by different methods for analyzing the arrhythmia. Methods: In 27 isolated rabbit heart preparations studied under the action of drugs (propranolol and KB-R7943) or physical procedures (stretching) that produce different degrees of change in the complexity of myocardial activation during ventricular fibrillation, use was made of spectral, morphological, and mapping techniques to process the recordings obtained with epicardial multielectrodes. Results: The complexity of ve…

Impact of osteoporosis and vertebral fractures on quality-of-life. a population-based study in Valencia, Spain (The FRAVO Study)

2011

Abstract Background To describe the health related quality of life in a population sample of postmenopausal women over the age of 50 and resident in the city of Valencia (Spain), according to the presence/absence of osteoporosis and the severity of prevalent morphometric vertebral fractures. Methods A cross-sectional age-stratified population-based sample of 804 postmenopausal women of 50 years of age and older were assessed with the SF-12 questionnaire. Information about demographic features, lifestyle, clinical features, educational level, anti-osteoporotic and other treatments, comorbidities and risk factors for osteoporosis were collected using an interviewer-administered questionnaire …

Predictors and prognosis for complex coronary lesions in patients with acute myocardial infarction

2007

Background We aimed to investigate the determinants and outcomes of multiple complex lesions (MCLs) on coronary angiography in patients with an acute myocardial infarction. Methods One thousand one hundred fifty-two consecutive nonselected myocardial infarction patients who underwent coronary angiography within 24 hours after admission were analyzed. A complex lesion was defined by the presence of thrombus, ulceration, irregular plaque, and flow impairment. Patients with ≤1 complex lesion were considered with single complex lesion (SCL), and patients with >1 complex lesions with MCLs. Results Multiple complex lesions were identified in 360 patients (31%). Patients from the MCL group were ol…

Fewer Type A personality traits in type 2 diabetes patients with diabetic foot ulcer.

2021

Abstract Aim Type A personality—characterized by time urgency, strong drive, and a need for achievement and competitiveness—has been shown to be associated with reduced mortality in patients with diabetes. However, it is not known whether a Type A personality might protect against diabetic foot ulcer (DFU). This prompted our present analysis of the association between Type A personality and DFU. Methods The Bortner Scale questionnaire was used to assess Type A personality in 386 patients with type 2 diabetes (T2D), including 104 patients also presenting with, and 282 presenting without, DFU. Additional questionnaires were used to assess perceived stress and depression. Results Type A Bortne…

The effect of timing on community acquired respiratory virus infection mortality during the first year after allogeneic hematopoietic stem cell trans…

2019

The effect of timing of community acquired respiratory virus (CARV) infection after allogeneic hematopoietic stem cell transplant (allo-HCT) is an as yet unsettled issue. We evaluate this issue by including all consecutive allo-HCT recipients with molecularly-documented CARV infection during the first year after transplant. The study cohort was drawn from a prospective longitudinal survey of CARV in allo-HCT recipient having respiratory symptoms conducted from December 2013 to December 2018 at two Spanish transplant centers. Respiratory viruses in upper and/or lower respiratory specimens were tested using multiplex PCR panel assays. The study cohort comprised 233 allo-HCT recipients with 37…

GEMS, a GEnetic and Metabolic Staging predicting the outcome of non-alcoholic fatty liver disease

2021

Background and Aim: Non-alcoholic fatty liver disease(NAFLD) is an emergent cause of liver-related events(LRE). We have assessed the ability of a composite score based on clinical features, metabolic comorbidities and genetic background, to predict LRE. Methods: 546 consecutive patients with NAFLD were recruited and stratified according to FIB-4(low risk <1.3;intermedium-high risk ≥1.3). LRE were defined as occurrence of HCC or hepatic decompensation. Cox regression multivariate analysis was used to identify baseline variables associated with LRE. Results: Over a median follow-up of 73.8 months, 58 patients experienced LRE(only 1 in the cohort of patients with FIB-4 65 years(HR 17.96), plat…
