Comparative analysis of observer depression scales

1985

Abstract The Hamilton Depression Scale (HAMD), Bech Rafaelsen Melancholia Scale (BRMS) and Montgomery Asberg Depression Rating Scale (MADRS) are analyzed according to mean discriminatory power, internal consistency, homogeneity and transferability. The analysis was done separately in different samples of patients with depressive syndromes: a) operationally defined depressive syndrome; b) Major Depressive Disorder (RDC); c) Major Depressive Disorder, endogenous type (RDC). BRMS and MADRS were superior to HAMD in all evaluated aspects. Further, the BRMS was superior to MADRS according to the criteria of homogeneity and transferability.

Analysis of shots in relation to the outcome in elite women's water polo matches. [Análisis de los lanzamientos en función del resultado en partidos …

2018

Abstract The aim of the current study was to investigate the shot performance of elite female water polo players according to their match outcome during three international tournaments, the 2012 Olympic Games, 2013 and 2014 FINA World Leagues. Twenty-four official matches footage [2012 Summer Olympic Games, n=8; 2013 FINA World League, n=8 and 2014 FINA World League, n=8] were obtained and analysed. The results showed that a similar playing style was used in both the 2012 and 2013 tournaments, independently of the outcome while in the 2014 FINA World League, winning teams performed more shots after displacement, more shots ending to zone 4 and scored more goals than losing ones (and fewer s…

Effet plancher des auto-questionnaires pour l’évaluation des résultats des prothèses totales de genou

2021

Abstract Background Patient reported outcome measurements (PROMs) that exhibit a substantial ceiling effect show clustering of participant's scores towards the upper limit of a scale and consequently have low discriminatory power among high end scores. This study aimed to compare ceiling effects at 1 and 2 years postoperatively across commonly used PROMs for TKA. Hypothesis We hypothesized, that the analyzed PROMs differ substantially in regards to their ceiling effect. Patients and methods Patients that underwent a primary unilateral TKA and completed pre-operative and post-operative questionnaires were included in the analysis. Participants completed the KOOS, KOOS-12, KOOS-JR, KOOS-PS, W…

Discriminatory power of water polo game-related statistics at the 2008 Olympic Games

2011

The aims of this study were (1) to compare water polo game-related statistics by context (winning and losing teams) and sex (men and women), and (2) to identify characteristics discriminating the performances for each sex. The game-related statistics of the 64 matches (44 men's and 20 women's) played in the final phase of the Olympic Games held in Beijing in 2008 were analysed. Unpaired t-tests compared winners and losers and men and women, and confidence intervals and effect sizes of the differences were calculated. The results were subjected to a discriminant analysis to identify the differentiating game-related statistics of the winning and losing teams. The results showed the difference…

Life Satisfaction and Self-rated Health in Adolescents: The Relationships between them and the Role of Gender and Age

2020

Abstract The purpose of this study was to analyze the relationships between self-reported life satisfaction, self-rated health, gender, and age in adolescents. 1,141 secondary school students aged between 12 and 17 participated in our study. The data were analyzed using bivariate and nonlinear canonical correlation analyses. The results of the bivariate correlation analysis support the results of previous studies. Life satisfaction was positively correlated with same-day perceived health (r = .37; p < .01) and negatively correlated with anxiety/depression (r = –.37; p < .01). Same-day perceived health was positively correlated with health in the past 12 months (r = .38; p < .01) an…

Value of morphotyping for the characterization of Candida albicans clinical isolates

2005

Until recently, morphotyping, a method evaluating fringe and surface characteristics of streak colonies grown on malt agar, has been recommended as a simple and unexpensive typing method for Candida albicans isolates. The discriminatory power and reproducibility of Hunter's modified scheme of Phongpaichit's morphotyping has been evaluated on 28 C. albicans isolates recovered from the oral cavity of asymptomatic human immunodeficiency virus-positive subjects, and compared to two molecular typing methods: randomly amplified polymorphic DNA (RAPD) fingerprinting, and contour clamped homogeneous electric field (CHEF) electrophoretic karyotyping. Morphological features of streak colonies allowed…

Assessment of microRNAs in patients with unstable angina pectoris.

2014

Aims While cardiac troponin measurements have significantly improved the early diagnosis of myocardial infarction, the timely biomarker-based diagnosis of unstable angina pectoris (UAP) remains a major unmet clinical challenge. The aim of this study was to assess levels of circulating microRNAs (miRNAs) as possible novel biomarkers in patients with UAP. Methods and results A three-phase approach was conducted, comprising (i) profiling of miRNAs in patients with UAP and controls groups; (ii) replication of significant miRNAs in an independent patient cohort, (iii) validation of a multi-miRNAs panel in a third cohort. Out of 25 miRNAs selected for replication, 8 miRNAs remained significantly …

Objective: Unruptured Intracranial Aneurysm (UIA) Treatment Score (UIATS) and PHASES score are used to inform treatment decision making for UIAs (treatment or observation). We assessed the ability of the scoring systems to discriminate between ruptured aneurysms and UIAs in a subarachnoid hemorrhage (SAH) cohort with multiple aneurysms.Methods: We retrospectively applied PHASES and UIATS scoring to the aneurysms of 40 consecutive patients with SAH and multiple intracranial aneurysms.Results: PHASES score discriminated better between ruptured aneurysms and UIAs than UIATS. PHASES scores and the difference between the UIATS subscores were higher for ruptured aneurysms compared with UIAs, whic…
