99mTc sestamibi as a prognostic factor of response to first-line therapy and outcome in patients with malignant lymphoma
(2013)INTRODUCTION: Resistance to chemotherapy poses a major problem in cancer patients. Although of multifactorial origin, some of the implicated mechanisms also interfere with Tc-MIBI uptake and retention in cancer cells. The ... -
Age- A nd sex-specific analysis of patients with embolic stroke of undetermined source
(2017)Objective: To investigate whether the correlation of age and sex with the risk of recurrence and death seen in patients with previous ischemic stroke is also evident in patients with embolic stroke of undetermined source ... -
Aspirin Versus Clopidogrel for Type 2 Diabetic Patients with First-Ever Noncardioembolic Acute Ischemic Stroke: Ten-Year Survival Data from the Athens Stroke Outcome Project
(2017)Background and objective Diabetes mellitus is associated with an increased risk of stroke and poor outcome following a stroke event. We assessed the impact of discharge treatment with aspirin versus clopidogrel on the ... -
“Blame it on the Comorbidities”: A 5-Year Follow-Up of 53 Chronic Dialysis-Dependent Patients Who Underwent Cardiac Surgery
(2016)Objectives This study evaluates midterm survival rates and risk factors for mortality of chronic dialysis-dependent patients undergoing cardiac surgery. Methods Fifty-three dialysis-dependent patients (34 males, aged 67 ± ... -
Carotid plaques and detection of atrial fibrillation in embolic stroke of undetermined source
(2019)OBJECTIVE: To investigate the association between the presence of ipsilateral nonstenotic carotid plaques and the rate of detection of atrial fibrillation (AF) during follow-up in patients with embolic strokes of undetermined ... -
Confidence intervals for differences between volumes under receiver operating characteristic surfaces (VUS) and generalized Youden indices (GYIs)
(2018)This article explores both existing and new methods for the construction of confidence intervals for differences of indices of diagnostic accuracy of competing pairs of biomarkers in three-class classification problems and ... -
Continuing versus Stopping Prestroke Antihypertensive Therapy in Acute Intracerebral Hemorrhage: A Subgroup Analysis of the Efficacy of Nitric Oxide in Stroke Trial
(2016)Background and purpose More than 50% of patients with acute intracerebral hemorrhage (ICH) are taking antihypertensive drugs before ictus. Although antihypertensive therapy should be given long term for secondary prevention, ... -
Daring-B: Discontinuation of effective entecavir or tenofovir disoproxil fumarate long-term therapy before HBsAg loss in non-cirrhotic HBeAg-negative chronic hepatitis B
(2018)Background: The remission rates after stopping antivirals in hepatitis B e antigen (HBeAg)-negative chronic hepatitis B (CHB) vary among studies, while reliable predictors of relapse have not been identified. This prospective ... -
Effect of host fruit, temperature and Wolbachia infection on survival and development of Ceratitis capitata immature stages
(2020)The Mediterranean fruit fly, Ceratitis capitata (Diptera: Tephritidae), holds an impressive record of successful invasions promoted by the growth and development of international fruit trade. Hence, survival of immatures ... -
Effects of early-life protein starvation on longevity and sexual performance of male medfly
(2019)Using a well-established model species for demographic, behavioural and aging research, the Mediterranean fruit fly (Ceratitis capitata), we explored whether nutritional stress early in adult life affects the sexual ... -
Embolic Stroke of Undetermined Source and Detection of Atrial Fibrillation on Follow-Up: How Much Causality Is There?
(2016)Background There is increasing debate whether atrial fibrillation (AF) episodes during follow-up in patients with embolic stroke of undetermined source (ESUS) are causally associated with the event. AF-related strokes are ... -
Genetic association analysis identifies variants associated with disease progression in primary sclerosing cholangitis
(2018)Objective Primary sclerosing cholangitis (PSC) is a genetically complex, inflammatory bile duct disease of largely unknown aetiology often leading to liver transplantation or death. Little is known about the genetic ... -
High resolution computed tomography findings on the lung of early breast-cancer patients treated by postoperative breast irradiation with a hypofractionated radiotherapy schedule
(2005)BACKGROUND: Hypofractionated breast radiotherapy (RT), although convenient for patients and health care systems, could have a negative impact on normal tissues such as lung. AIM: To evaluate radiation-induced lung toxicity ... -
Intra-Abdominal Hypertension is a Risk Factor for Increased VAP Incidence: A Prospective Cohort Study in the ICU of a Tertiary Hospital
(2020)Background: Ventilator-associated pneumonia (VAP) might be increased in cases with intra-abdominal hypertension (IAH). However, despite animal experimentation and physiological studies on humans in favor of this hypothesis, ... -
Major hepatic complications in ursodeoxycholic acid-treated patients with primary biliary cholangitis: Risk factors and time trends in incidence and outcome
(2018)Objectives: In this era of near universal ursodeoxycholic acid (UDCA) treatment for primary biliary cholangitis (PBC), progression to cirrhosis still occurs in an important proportion of patients. The aim of this study was ... -
The Medical Research Council chronic dyspnea score predicts the survival of patients with idiopathic pulmonary fibrosis
(2008)Background: The Medical Research Council (MRC) chronic dyspnea scale (6-point) is used in different clinical conditions to grade breathlessness on daily activities. We have previously shown that in patients with histologically ... -
