Mobilization of endothelial progenitor cells in acute cardiovascular events in the PROCELL study: Time-course after acute myocardial infarction and s…
2015
The mobilization pattern and functionality of endothelial progenitor cells after an acute ischemic event remain largely unknown. The aim of our study was to characterize and compare the short- and long-term mobilization of endothelial progenitor cells and circulating endothelial cells after acute myocardial infarction or atherothrombotic stroke, and to determine the relationship between these cell counts and plasma concentrations of vascular cell adhesion molecule (VCAM-1) and Von Willebrand factor (VWF) as surrogate markers of endothelial damage and inflammation. In addition, we assessed whether endothelial progenitor cells behave like functional endothelial cells. We included 150 patients…
The Role of Third Ventriculostomy in the Management of Obstructive Hydrocephalus
2003
Objective: Endoscopic third ventriculostomy (ETV) is an effective treatment for occlusive hydrocephalus caused by an obstruction of the CSF flow in the aqueduct or the posterior fossa. We evaluated the factors age, pathology and surgical technique on the results of the ETV. Methods: Between November 1992 and October 2000 171 ETV have been performed in 159 patients. The follow-up was evaluated in 150 patients. The age ranged from 10 days to 77 years (mean age 35 years). The hydrocephalus was caused by benign aqueductal stenosis in 77 patients, space-occupying lesions in 59, by intraventricular hemorrhages in 11, and by other causes in 3 patients. The trajectory was planned in 31 patients by …
Management and long-term follow-up of early stage H. pylori-associated gastric MALT-lymphoma in clinical practice: An Italian, multicentre study
2009
Abstract Background/Aim Data on management and long-term follow-up of Helicobacter pylori -associated MALT-lymphoma in clinical practice are scanty. We evaluate the long-term efficacy of H. pylori eradication on low-grade MALT-lymphoma, and the efficacy of further therapies in refractory patients. Methods This study enrolled patients with stages I–II 1 MALT-lymphoma and H. pylori infection. H. pylori eradication was attempted in all patients. Patients with lymphoma persistence or progression following H. pylori treatments received further lymphoma treatments. Both 5-year and disease-free survivals were calculated. Results Sixty patients (stage I/II 1 : 50/10) were followed up for a median t…
Assessment of corneal morphological changes induced by the use of daily disposable contact lenses.
2015
To assess the effect of different disposable soft contact lenses upon corneal thickness, and upon anterior and posterior corneal curvatures using a dual-Scheimpflug imaging based device.Twenty-eight young, healthy subjects wore four different types of daily disposable soft contact lenses on four different days: Dailies Total1, Proclear 1 Day, Clariti 1-Day and 1-Day Acuvue Moist. The lenses had different material and water content. Pachymetry maps and keratometry values were obtained using the Galilei G4 twice a day: one before putting the lens on and one after an eight-hour period of contact-lens wear. Measurements were also recorded without any contact lenses being worn during a day.Clari…
Long-term comparison of corneal aberration changes after laser in situ keratomileusis: mechanical microkeratome versus femtosecond laser flap creatio…
2010
Purpose To compute and compare visual acuity, refractive outcomes, and anterior corneal aberration changes after myopic laser in situ keratomileusis (LASIK) with flap creation by a mechanical microkeratome and by a femtosecond laser. Setting Private practice refractive surgery center, Valencia, Spain. Design Comparative case series. Methods Patients were assigned to have LASIK flap creation with a mechanical microkeratome (Carriazo-Barraquer) or a femtosecond laser (IntraLase). The Visx S2 excimer laser was used for myopic ablation in all cases. Main outcome measures included uncorrected and corrected distance visual acuities and the defocus equivalent. Higher-order aberrations (HOAs) were …
Expiratory airflow obstruction due to tracheostomy tube: A spirometric study in 50 patients
2018
OBJECTIVES Tracheostomy is commonly used in intensive care units and in head and neck departments. Airway obstruction due to occluded cuffless tracheostomy tubes themselves remains unknown, although capping trials are commonly used before decannulation. The aim of this study was to evaluate the extent to which airway obstruction can be caused by occluded cuffless tubes in patients who underwent head and neck surgery. DESIGN Prospective Research Outcome. SETTINGS University teaching hospital. PARTICIPANTS Fifty patients requiring transient tracheostomy after head and neck surgery. MAIN OUTCOME MEASURES A flow-volume loop (FVL) through the mouth using a portable spirometer, with the occluded …
Long-term metabolic effects in patients with urinary diversion
1998
The use of intestinal segments in genitourinary reconstruction could influence vitamin metabolism and affect the skeletal bone and its mineral content in the long term. In 137 patients, serum levels of the vitamins A, B1, B2, B6, B12, D, and E and of folic acid, bile acid, and ammonia as well as levels of intracorpuscular vitamin B12 and folic acid were examined and a red blood cell count was performed. The patients were divided into three groups (or = 2 years,2 toor = 4 years, and4 years after surgery) as well as into children and adults. In addition, bone mineral density (dual-photon absorptiometry) was measured in 25 patients. Of these, 16 patients were approximately 16.8 years s/p recta…
Changes in physical activity among coronary and hypertensive patients: A longitudinal study using the Health Action Process Approach
2017
Objectives: Physical activity (PA) is a key factor in cardiovascular disease prevention. Through the Health Action Process Approach (HAPA), the present study investigated the process of change in PA in coronary patients (CPs) and hypertensive patients (HPs). Design: Longitudinal survey study with two follow-up assessments at 6 and 12 months on 188 CPs and 169 HPs. Main outcome measures: Intensity and frequency of PA. Results: A multi-sample analysis indicated the equivalence of almost all the HAPA social cognitive patterns for both patient populations. A latent growth curve model showed strong interrelations among intercepts and slopes of PA, planning and maintenance self-efficacy, but chan…
Combined effects of shiftwork and individual working time control on long-term sickness absence: a prospective study of finnish employees
2014
Objective To investigate whether the effects of shiftwork on long-term sickness absence vary according to the level of individual working time control (WTC). Methods A representative sample of Finnish employees (1447 men and 1624 women) was combined with a register-based follow-up. A negative binomial model was used in the analysis of long-term sickness absence days. The results were adjusted for various background and work-related factors. Results Individual WTC decreased long-term sickness absence. The higher rate of sickness absences in shiftwork was mainly due to the lower level of WTC. Working time control decreased sickness absence equally in day work and shiftwork. Conclusions The ne…
Do low burnout and high work engagement always go hand in hand? Investigation of the energy and identification dimensions in longitudinal data
2011
The aim of the present 2-year follow-up study among young managers (N=433) was to investigate the intraindividual developmental patterns of burnout and work engagement as well as their interconnections. More specifically, we examined the interconnectedness of the varying patterns (i.e., latent classes) of exhaustion and vigor (i.e., the energy dimension) and cynicism and dedication (i.e., the identification dimension) across time. The latent class solutions supported by the growth mixture modeling indicated four latent classes for exhaustion and five for vigor. In addition, four latent classes were found for cynicism and six for dedication. Cynicism and dedication represented opposites with…
