Effect of 3rd-order aberrations on human vision
2007
To investigate the effect of 3rd-order aberrations on human vision.Grupo de Ciencias de la Visión, University of Murcia, Murcia, Spain.The 3rd-order aberrations coma and trefoil were induced with purpose-designed soft contact lenses, 3 inducing coma (low [0.05 microm], medium [0.13 microm], high [1.03 microm]) and 3 inducing trefoil (low [0.07 microm], medium [0.17 microm], high [0.96 microm]). Monocular high-contrast (HCVA) and low-contrast (LCVA) visual acuities and contrast sensitivity were measured in 11 subjects wearing contact lenses with a 5.0 mm artificial pupil.The reduction in HCVA and LCVA was statistically significant only for the highest coma and trefoil values (P.0001). For co…
Forty-slice MDCT enteroclysis: evaluation after oral administration of isotonic solution in Crohn's disease.
2007
Objective. The aim of this study was to evaluate the accuracy of multidetector computed tomography (MDCT) enteroclysis after oral hyperhydration with isotonic solution in detecting bowel wall alterations in patients with Crohn’s disease. Materials and methods. Twenty-eight patients with a diagnosis of Crohn’s disease established by ileocolonoscopy and histology were enrolled in the study; 15 patients with negative ileocolonoscopy served as controls. In all cases, MDCT enteroclysis was performed after oral administration of 2,000 ml of isotonic solution and intravenous administration of N-butylscopolamine. Axial, isotropic multiplanar and volume-rendered reconstructions were used to evaluate…
Efficacy of the treatment with prostaglandin E-1 in venous ulcers of the lower limbs.
2005
Background. Venous ulcers represent an important medical problem due to their high prevalence and consequent sanitary costs. In this study we evaluated the effect of Prostaglandin E-1 (PGE-1), a drug that improves district ischemia, on the healing of venous ulcers. Methods. We performed a randomized, placebo-controlled, single blind study, in which 87 patients, carriers of venous leg ulcers, homogeneous for dimensions and characteristics, were treated for 20 days an with infusion of Prostaglandin E-1 or placebo, in association with a topic therapy. The dimension and the number of the ulcers were determined at the beginning of the treatment and then every 20 days up to 4 months or until tota…
Patient and physician views on the quality of care in inflammatory bowel disease: Results from SOLUTION-1, a prospective IG-IBD study
2014
Remarkable differences in quality of care (QoC) might be observed in different countries, affecting quality of life of inflammatory bowel disease (IBD) patients. The aim of this study was to assess patient and physician perceptions of the QoC in Italy.A multicentre observational study on the quality of care in IBD (SOLUTION-1) was conducted in 36 IG-IBD (Italian Group for Inflammatory Bowel Disease) centres in Italy. The QUOTE-IBD (Quality of Care Through the Patient's Eyes) questionnaire was administered to IBD patients and to the attending physicians. The Quality Impact (QI) score summarises the QUOTE-IBD questionnaire, and a QI9 is considered satisfactory.Nine-hundred-ninety-two patients…
Hepatitis E virus infection as a cause of acute hepatitis in Southern Italy
2011
Abstract Background Hepatitis E virus (HEV) is a major cause of acute hepatitis in developing countries, whereas it is not considered a major health problem in Western World. Aims To investigate the spread of HEV and its possible role in causing acute hepatitis in Southern Italy. Methods Four hundred and thirty patients observed from April to December 2009 were studied and grouped as follows: 55 individuals with acute hepatitis (AH), 33 of whom cryptogenic; 321 individuals with chronic liver diseases (CLD), (278 Italians and 43 immigrants); 54 individuals without liver disease (control-group). Serum samples from all cases were tested for IgG anti-HEV antibodies and those positive to this te…
TRANSCRANIAL DIRECT CURRENT STIMULATION ENHANCES SUCKING OF A LIQUID BOLUS IN HEALTHY HUMANS
2014
Abstract Background Transcranial direct current stimulation (tDCS) is a non-invasive technique used for modulating cortical excitability in vivo in humans. Here we evaluated the effect of tDCS on behavioral and electrophysiological aspects of physiological sucking and swallowing. Methods Twelve healthy subjects underwent three tDCS sessions (anodal, cathodal and sham stimulation) on separate days in a double-blind randomized order. The active electrode was placed over the right swallowing motor cortex. Repeated sucking and swallowing acts were performed at baseline and at 15 and 60 min after each tDCS session and the mean liquid bolus volume ingested at each time point was measured. We also…
Analysis of the in vitro cytokine production by liver-infiltrating T cells of patients with autoimmune hepatitis.
1993
SUMMARY The pathogenic mechanisms underlying the development of autoimmune hepatitis (AIH) are still unclear. Since AIH is associated with the presence of various autoantibodics and certain HLA subtypes, it is likely that T and B cells play a major role in this disease. In this study we have determined the functional capacities of in vivo preactivated liver-infiltrating T cells (LTC) from patients with AIH. As controls we used LTC from patients with non-autoimmune hepatitis (non-AIH). Our results show that preactivated LTC from patients with AIH predominantly (190/255 clones) reside in the CD4+ population, whereas LTC in non-AIH are dominated by the CD8+ phenotype (148/254 clones). In view …
Links between maternal feeding practices and children's eating difficulties. Validation of French tools
2012
Abstract: The main objectives of the study were to validate a measure of young children's eating difficulties and maternal feeding practices in a French sample, and to assess the links between these practices and children's eating difficulties. Mothers of French children aged 20-36 months completed 4 questionnaires that were validated using a Structural Equation Modelling approach. Links between children and maternal components were investigated using a PLS regression. The Children's Eating Difficulties Questionnaire yielded a 4-dimension solution: Neophobia, Pickiness, Low Appetite and Low Enjoyment in food. The Feeding Style Questionnaire assessed 3 dimensions: Authoritarian, Authoritativ…
Development of a Food-Based Diet Quality Score from a Short FFQ and Associations with Obesity Measures, Eating Styles and Nutrient Intakes in Finnish…
2019
We constructed a food-based diet quality score (DQS) and examined its association with obesity measures, eating styles and nutrient intakes. Participants were 3592 individuals (764 dizygotic [DZ] and 430 monozygotic [MZ] twin pairs) from the FinnTwin16 study. The DQS (0&ndash
Appropriateness guidelines and predictive rules to select patients for upper endoscopy: a nationwide multicenter study.
2010
OBJECTIVES: Selecting patients appropriately for upper endoscopy (EGD) is crucial for efficient use of endoscopy. The objective of this study was to compare different clinical strategies and statistical methods to select patients for EGD, namely appropriateness guidelines, age and/or alarm features, and multivariate and artificial neural network (ANN) models. METHODS: A nationwide, multicenter, prospective study was undertaken in which consecutive patients referred for EGD during a 1-month period were enrolled. Before EGD, the endoscopist assessed referral appropriateness according to the American Society for Gastrointestinal Endoscopy (ASGE) guidelines, also collecting clinical and demogra…
