And Gender

Summary: Hare's Psychopathy Checklist - Revised (PCL-R; Hare, 1991 ) was originally constructed for use among males in correctional and forensic settings. In this study, the PCL-R protocols of 36 matched pairs of female and male violent offenders were examined with respect to gender differences. The results indicated a few significant differences. By means of discriminant analysis, male Ss were distinguished from their female counterparts through their relatively higher scores on “callous/lack of empathy” (item 8) and “juvenile delinquency” (item 18), whereas the female Ss scored relatively higher on “promiscuous sexual behavior” (item 11). Some sources of bias and possible implications are discussed.

SummaryIt is important to understand compliance and persistence with medication use in the clinical practice of osteoporosis treatment. The purpose of this work is to describe the “intravenous ibandronate versus oral alendronate” (VIVA) study, a non-interventional trial to assess the compliance and persistence of osteopenic postmenopausal women with treatment via weekly oral alendronate or intravenous ibandronate (Bonviva®) every three months.4477 patients receiving ibandronate 3 mg i. v. quarterly and 1491 patients receiving alendronate 70 mg orally weekly were included in the study. Matched pairs of 901 subjects in each group were also generated. Matching was performed on the basis of age, body mass index, fracture history at study inclusion, prior treatment with bisphosphonates and the number of concomitant disorders. Secondary outcome measures of osteoporosis related fractures, mobility restriction and pain, analgesia, quality of life questionnaires as well as attitudes to medications were assessed. The primary outcome parameters of compliance and persistence will be tracked in these subjects.At baseline, the entire collectives differed significantly on body weight (less in ibandronate group), duration since osteo - porosis diagnosis (longer in ibandronate), and incidence of prior osteoporotic fracture (higher in ibandronate group). The matched-pairs differed only on mobility restriction and quality of life (both worse in ibandronate group).The results from the VIVA study trial will provide scientific rationale for clinical recommendations in the pharmacological treatment of postmenopausal osteoporosis.

80 emotionally disturbed and 80 neurologically impaired boys in a public school setting were matched for WISC Full Scale IQ and chronological age. An analysis was made of the Similarities subtest responses utilizing both the error-analysis method of Spence and the cognitive style procedure of Sigel for purposes of comparison. The Wilcoxon matched-pairs signed-ranks technique was used in analyzing the data. The results were as follows: (1) the error analysis approach provided the greater potential for differential diagnosis between the two groups under consideration; (2) use of the cognitive style scores permitted improved definition of the dynamic implications of the error-analysis categories, inadequate abstracting and narrative-descriptive responses; (3) diagnostic power was not increased when all responses as opposed to errors alone were considered.

We investigate Hopf braces, a concept recently introduced by Angiono, Galindo and Vendramin [I. Angiono, C. Galindo and L. Vendramin, Hopf braces and Yang–Baxter operators, Proc. Amer. Math. Soc. 145 (2017) 1981–1995] in connection to the quantum Yang–Baxter equation. More precisely, we propose two methods for constructing Hopf braces. The first one uses matched pairs of Hopf algebras while the second one relies on category-theoretic tools.

Abstract Objective: To compare the pain expected to that effectively caused by magnetic resonance arthrography of the shoulder and, secondarily, to describe a simplified approach to the technique for articular access. Materials and Methods: We prospectively evaluated 40 participants who used a visual analog scale and a simplified categorical scale to indicate the level of pain expected and that experienced after the procedure, comparing the two with the Wilcoxon matched-pairs test. We also determined gender-related differences in pain conditions using the Mann-Whitney U test. In addition, we described a modified technique involving radiographic localization and the use of standard puncture needles for articular access. Results: Analysis of the visual analog scales showed that the pain experienced was less than had been expected, with median scores of 1.75 and 3.75, respectively (p < 0.001). The level of pain expected was higher among women than among men, with median scores of 8.0 and 3.0, respectively (p = 0.014), as was the level of pain experienced, with median scores of 3.0 and 1.5, respectively (p = 0.139). The overall categorical evaluation corroborated that difference (p = 0.03). Articular access with the modified technique was successful in all patients. Conclusion: Magnetic resonance arthrography of the shoulder is less painful than patients expect. In addition, digital radiographic guidance combined with the use of standard puncture needles appears to improve the efficiency of the method.
