Differential transcriptomic profile in spermatozoa achieving pregnancy or not via ICSI
2010
Basic sperm analysis is limited as a method of estimating pregnancy. This study’s objective was use of microarray technology to differentiate the gene expressions of spermatozoa that achieved pregnancy in an intracytoplasmic sperm injection (ICSI)cycle in an oocyte donation programme with those that did not achieve pregnancy. A study of nested cases and controls was designed to evaluate fresh and frozen spermatozoa from infertile males undergoing ICSI with donor oocytes. The global genome expression of pooled samples from each group (achieving pregnancy versus those that didn’t, from fresh or frozen spermatozoa)was compared using microarray analysis. The level of expression of some of the t…
Hysteroscopic resection of the septum improves the pregnancy rate of women with unexplained infertility: a prospectine controlled trial
2009
Objective: To assess fecundity of infertile women after surgical correction of uterine septum. Design: Prospective controlled trial. Setting: Three academic infertility clinics. Patient(s): Forty-four women affected by septate uterus and otherwise unexplained infertility represented the study group (group A), and 132 women with unexplained infertility were enrolled as control subjects (group B). Intervention(s): Hysteroscopic metroplasty was performed in group A, and group B was managed expectantly. All women were followed-up for 1 year without any other intervention. Main Outcome Measure(s): Fecundity rate was calculated as the number of pregnancies per 100 person-months Result(s): Pregnan…
Effect of sperm DNA fragmentation on pregnancy outcome depends on oocyte quality
2010
Objective To quantify the effect of sperm DNA fragmentation (SDF) on reproductive outcome by evaluating the most statistically significant bias factors using logistic regression. Design Prospective blind observational cohort study. Setting University affiliated private IVF unit. Patient(s) Two hundred ten male partners of couples undergoing in vitro fertilization (IVF) or first intracytoplasmic sperm injection (ICSI) cycles with fresh or thawed sperm with the women's own or donated oocytes. Intervention(s) None. Main Outcome Measure(s) SDF determined before and after swim-up (n = 420), odds ratio calculated of the effect of an increase of one unit of SDF on pregnancy, and stratified regress…
Improvement of inter-rater reliability of PANSS items and subscales by a standardized rater training.
1998
The present evaluation focused on the inter-rater reliability of single items and subscales of the Positive and Negative Syndrome Scale (PANSS) before and after a standardized rater training. The results of two independent studies comprising n=23 (study I) and n=12 (study II) psychiatrists and videotaped interviews with schizophrenic patients were analysed. Chance-corrected coefficients of rating agreement with expert standards (weighted kappa) were computed for single items and subscales of the PANSS. The results clearly demonstrate the importance of rater trainings. After three training sessions, 90% of the PANSS items reached an acceptable level of reliability (kappa(w)>0.40) in both eva…
Knowledge about glaucoma in the unselected population: a German survey.
2002
Purpose To determine the general population's knowledge about glaucoma. Materials and methods A representative survey of the German population was conducted in which 2,742 men and women were interviewed face to face. The sample was matched with the German population for age, sex, education, income, and other factors. Questions were asked concerning the nature, occurrence, possible risk factors, and course of glaucoma. Results Fifty-one percent of the population had an active knowledge of the term "glaucoma" and 75% had a passive knowledge of the term. Of those interviewees with a passive knowledge, glaucoma was thought to be associated with raised intraocular pressure (IOP) by 28% and loss …
Objective measurement of intraocular forward light scatter using Hartmann-Shack spot patterns from clinical aberrometers. Model-eye and human-eye stu…
2007
Purpose To apply software-based image-analysis tools to objectively determine intraocular scatter determined from clinically derived Hartmann-Shack patterns. Setting Aston Academy of Life Sciences, Aston University, Birmingham, United Kingdom, and Department of Optics, University of Valencia, Valencia, Spain. Methods Purpose-designed image-analysis software was used to quantify scatter from centroid patterns obtained using a clinical Hartmann-Shack analyzer (WASCA, Zeiss/Meditec). Three scatter values, as the maximum standard deviation within a lenslet for all lenslets in the pattern, were obtained in 6 model eyes and 10 human eyes. In the model-eye sample, patterns were obtained in 4 sessi…
The development of a Spanish language version of the Worn Out scale of the General Well-Being Questionnaire (GWBQ).
2006
The paper describes the development of a short Spanish-language version of the General Well-Being Questionnaire (GWBQ; Cox & Gotts, 1987), based on the 12 items of its Worn Out scale. Research has shown the English-version Worn Out scale to be sensitive to aspects of the design and management of work. This study aimed to test its cross-cultural consistency in a Spanish-language workplace context. The data were collected from a sample of 229 workers in Valencia (Spain). Confirmatory Factor Analyses showed the factorial validity, reliability, and concurrent validity of the new Spanish version to be adequate. The sensitivity of the new measure to safety behavior and the reporting of accide…
The Spanish-Version of the Subjective Vitality Scale: Psychometric Properties and Evidence of Validity.
2017
AbstractThe Subjective Vitality Scale (SVS) assess the subjective experience of being full of energy and alive, a clinically relevant outcome measure of positive psychological well-being. The purpose of this paper was to translate the 7-item SVS into Spanish and examine its psychometric properties. In Study 1 (n = 790 adolescents) and Study 2 (n = 130 athletes) reliability and exploratory factor analysis (EFA) were carried out. In Study 1 and Study 3 (n = 197 dancers) evidence of validity of inferences based on SVS scores estimating relationships with other variables (life satisfaction, global self-esteem and emotional and physical exhaustion) was obtained. In Study 2 invariance across time…
Is the breadth of individualized ranges of optimal anxiety (IZOF) equal for all athletes? A graphical method for establishing IZOF.
2001
Recall and direct methods to determine the individual zone of optimal functioning (IZOF) cannot account for potential individual differences in the span of optimal anxiety. Accordingly, an attempt was made to test a graphical technique that could establish the span of optimal anxiety ranges for individuals. State anxiety (STAI; Spielberger, Gorusch, & Lushene, 1970; and CSAI-2; Martens, Burton, Vealey, Bump, & Smith, 1990) was assessed before competitions (10 to 20) in six Spanish golfers during a season. Performance in each match was determined using golf scores and self-ratings. Optimal anxiety ranges were established graphically by plotting individual scores of precompetition anx…
Validation of a New Instrument for Self-care in Spanish Palliative Care Professionals Nationwide.
2015
AbstractSelf-care is a cornerstone issue for those who deal with stressful events, as it is the case of palliative care professionals. It has been related to awareness, coping with death and quality of life, among others, but no measurement instruments have been used in palliative care professionals. This research presents and validates a brief new measure with clinical and psychometric good properties, called Professional Self-Care Scale (PSCS). The PSCS assesses professionals’ self-care in three areas: physical self-care, inner self-care, and social self-care. Data come from a cross-sectional survey in a sample of 385 professionals of palliative care. The Mindful Attention Awareness Scale…
