Role of cytomegalovirus (CMV)-specific polyfunctional CD8+ T-cells and antibodies neutralizing virus epithelial infection in the control of CMV infec…
2015
The role of cytomegalovirus (CMV)-specific polyfunctional CD8+ T-cells and that of antibodies neutralizing virus epithelial infection (AbNEI) in the control of CMV DNAemia were investigated in 39 CMV-seropositive allogeneic stem-cell transplant (Allo-SCT) recipients with (n = 24) or without (n = 15) CMV DNAemia. AbNEI levels were monitored prospectively by means of a neutralization assay employing retinal epithelial cells (ARPE-19) and the recombinant CMV strain BADrUL131-Y4. Quantification of CMV-specific polyfunctional CD8+ T-cells (expressing two or three of the following markers: IFN-γγ, TNF-α and CD107a) in whole blood was performed by flow cytometry for intracellular cytokine staining…
Tracheomalacia Repair Using Ceramic Rings
1992
Tracheomalacia resulting from tracheostomy or compressive thyroid disease often represents a difficult problem in airway management. In an attempt to improve this condition, biocompatible ceramic rings were surgically implanted in 16 patients to restore normal patency of the airway by first expanding the tracheal lumen lateral, and then in an anterior dimension. Preoperatively, patients displayed moderate to severe obstruction with marked restrictions in lifestyle, as confirmed by history, physical examination, and airway resistance studies. Additionally, three of these patients were trach-dependent at the time of implantation. Postoperatively all 16 patients have normal airway resistance p…
Mother-child interactional patterns in high-and low-risk mothers
1998
Abstract Objective: The aim of the present study was to determine the extent to which mother-child interactional patterns in high-and low-risk (for child physical abuse) mothers were similar to patterns observed in physically abusive parents. Method: Ten high-risk and 10 demographically similar low-risk mother-child dyads were studied. Trained observers coded maternal-child interaction patterns in the home during five 1-hour periods using the Standardized Observation Codes system. Results: As expected, high-risk mothers made fewer neutral approaches to their children, displayed more negative behaviors toward their children, and made more indiscriminant responses to their children's prosocia…
Intrasubject repeatability of corneal power, thickness, and wavefront aberrations with a new version of a dual rotating Scheimpflug–Placido system
2014
Purpose To determine the intrasubject repeatability of a recently introduced dual-camera rotating Scheimpflug–Placido imaging system (Galilei G4) in determining corneal thickness, power, and wavefront aberrations in young healthy subjects. Setting University of Valencia, Valencia, Spain. Design Prospective evaluation of diagnostic technology. Methods The study comprised right eyes of 25 subjects aged 20 to 40 years with a spherical equivalent ranging from −4.25 to +1.00 diopters. The central corneal thickness, thinnest point value and location, anterior and posterior surface curvatures, total corneal power, and corneal wavefront aberrations were measured for distance vision using the dual S…
Hand‐related action words impair action anticipation in expert table tennis players : Behavioral and neural evidence
2021
Athletes extract kinematic information to anticipate action outcomes. Here, we examined the influence of linguistic information (experiment 1, 2) and its underlying neural correlates (experiment 2) on anticipatory judgment. Table tennis experts and novices remembered a hand- or leg-related verb or a spatial location while predicting the trajectory of a ball in a video occluded at the moment of the serve. Experiment 1 showed that predictions by experts were more accurate than novices, but experts’ accuracy significantly decreased when hand-related words versus spatial locations were memorized. For nonoccluded videos with ball trajectories congruent or incongruent with server actions in exper…
Perception of Coaching Behaviors, Coping, and Achievement in a Sport Competition
2011
This study examined the relationship between perceived coaching behaviors, coping strategies during a sport competition, and sport achievement. A prospective design was used in which 80 athletes from individual sports completed measures of perceived coaching behaviors two days before a competition (Time 1) and measures of coping and sport achievement within three hours after a sport competition (Time 2). As expected, results of multiple regressions indicated that supportive coaching was a positive predictor of task-oriented coping and sport achievement whereas unsupportive coaching was a positive predictor of disengagement-oriented coping. Both types of coping were significantly associated …
Myopia and Cognitive Performance: Results From the Gutenberg Health Study.
2016
Purpose To analyze the association between myopia and cognitive performance. Methods A cohort of the population-based Gutenberg Health Study included 3819 eligible enrollees between 40 and 79 years. We used the Tower of London (TOL) test to assess cognitive performance. Myopia was defined as a spherical equivalent (SE) ≤ -0.5 diopters (D) via noncycloplegic autorefractometry. We conducted linear mixed models with the SE as the dependent variable and the age, sex, duration of education, and TOL score as covariates. Results Complete data were available for 3452 participants (90.4%). The mean TOL score was 14.0 ± 3.9 in the myopes versus 12.9 ± 4.0 in the nonmyopes (P < 0.001). The mean TOL sc…
Malondialdehyde in early phase of acute pancreatitis
2011
Aims: to assess oxidative stress in acute pancreatitis, its evolution over time and its relationship with the severity of the disease. Methods: during a two-year period, patients with acute pancreatitis with less than 24 hours of pain were evaluated. Serum was obtained the first, second and fourth day from admittance, if complications were detected, and after recovery. Malondialdehyde was determined by high performance liquid chromatography. Twenty healthy volunteers constituted the control group. Malondialdehyde between groups was compared with Mann-Whitney and Kruskal-Wallis tests; malondialdehyde evolution was studied with Wilcoxon test. Results: one hundred and sixty-nine patients were …
Impact of pharmaceutical intervention on quality of life and coping strategies in patients with haematological malignancies
2015
Summary Objectives We conducted a prospective study approved by the local ethics committee to determine the impact of a pharmaceutical intervention (PI) on pain, fatigue, quality of life (QoL) and coping strategies in patients with HMs starting chemotherapy sessions. Material and methods Patients received either usual care (UC) + PI (PI group) or UC alone (UC group). They had to complete 2 questionnaires, QLQ-C30 and MAC 21, at 3 different time points: before starting the 1st chemotherapy session (T1), during the intercure (T2) and the day before starting the 2nd chemotherapy session (T3). To determine predictive factors of pain, fatigue, QoL and coping scores at T3, a multivariate ANOVA wa…
Precision of a commercial hartmann-shack aberrometer: limits of total wavefront laser vision correction.
2012
Purpose To assess the intrasession and intersession precision of higher-order aberrations (HOAs) measured using a commercial Hartmann-Shack wavefront sensor (Zywave; Bausch & Lomb) in refractive surgery candidates. Design Prospective, experimental study of a device. Methods To analyze intrasession repeatability, 1 experienced examiner measured 30 healthy eyes 5 times successively. To study intersession reproducibility, the same clinician obtained measurements from another 30 eyes in 2 consecutive sessions at the same time of day 1 week apart. Results For intrasession repeatability, excellent intraclass correlation coefficients (ICCs) were obtained for total ocular aberrations, total HOAs, a…
