A Prospective PMS Study to Validate the Sensitivity for Change of the D-Scale in Advanced Stages of Dementia Using the NMDA-Antagonist Memantine
No full textThe present postmarketing surveillance (PMS) study is the first large scale systematic and prospective clinical trial of pharmacotherapeutic intervention in advanced stages of dementia. Within a validation program this study aimed at demonstrating the sensitivity of the D-Scale of change (DS-C) for measuring ADL-function. Efficacy of treatment with the NMDA-antagonist memantine[1] was investigated in 531 patients with advanced dementia employing a parallel group design that stratified patient cohorts by severity according to GDS stages (Reisberg, 1992). Efficacy was determined on two independent levels: by the assessment of the physicians' Clinical Global Impression of Change (CGI-C) at the end of a 6-week observation period, and by the assessment of change in elementary ADL-functions by the caregivers using the D-Scale-of-Change. With the D-Scale-of-Change the caregivers can assess a change in broad functional items, i.e. cognitive and motor functions and also elementary functions of daily life. The effect size of this improvement increased constantly during the observation period. Even in patients of GDS stage 7 an improvement could be measured. These results were also seen by the physicians, who recorded an overall clinical improvement in 75.5 % of the patients after 6 weeks. Tolerability evaluations resulted in the ratings “very well” by 59.5 % or “well” by 35.0 % of the patients. No serious adverse drug reactions occurred. A correlation analysis demonstrated a high congruency of both assessments. Furthermore, the observed time course of these improvements paralleled with the time course of symptomatic benefit by effects of memantine that had been repeatedly demonstrated in randomised, double-blind, placebo-controlled studies in mild to moderate dementia. Together with the evaluation of the scale-properties of the D-Scale for assessment of severity the D-Scale and the D-Scale-of-Change can be regarded as validated
Medial saphenous fasciocutaneous and myocutaneous free flap transfer in eight dogs
No full textSkin defects on the distal extremity (n = 7) or face (n = 1) of eight dogs were repaired using a medial saphenous fasciocutaneous or myocutaneous flap. The cause of the wounds were ablative oncological surgery (n = 4), trauma (n = 3), or radiation burn (n = 1). The flap was removed from the medial femorotibial region, and transferred to the wound bed. The vascular supply to the flap was reestablished via microvascular anastomosis of the medial saphenous vessels of the flap to recipient vessels isolated adjacent to the wound. Three flaps incorporated the distal half of the caudal head of the sartorius muscle to form a myocutaneous free flap. All flaps survived completely. The medial saphenous fasciocutaneous and myocutaneous free flaps were found to be reliable and cosmetically acceptable for repair of skin defects in dogs.LR: 20061115; PUBM: Print; JID: 8113214; ppublishSource type: Electronic(1
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Healing responses of the lower urinary tract
No full textHealing of the urinary tract follows a series of events similar to other epithelial surfaces. This process, however, occurs more rapidly in the urinary tract. A variety of factors that can affect the healing response of the urinary tract are presented in this article. It is important for the veterinarian to be aware of these factors so that the appropriate surgical or medical treatment can be provided to the patient to optimize the healing processes.LR: 20061115; PUBM: Print; JID: 7809942; RF: 41; ppublishSource type: Electronic(1
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
