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
A lycopene and olives vegetation water compound improves lower urinary tract symptoms in men with histologically-proven benign prostatic hyperplasia and inflammation
No full textBackground and aims. There is evidence for the ability of antioxidants to counteract the effects of inflammation. We aimed to determine whether the administration of a lycopene/olives vegetation water compound might reduce prostatic inflammation and consequent lower urinary tract symptoms in patients with histologically proven prostatic inflammation. Methods. Over a month period, patients having undergone prostate biopsy and having been diagnosed with benign prostate were given lycopene/olives vegetarian water compound (Group A). Data were compared with those of a matched population of patients who did not receive such treatment (Group B). International prostate symptom score, peak flow rate and post-void residual were recorded before and at the end of treatment. Results. The 17 patients in group A and the 17 in group B, had similar age, PSA, prostate volume, peak flow rate and post-void residual, but patients in Group A had lower median international prostate symptoms score than those in group B (7 vs 12; p = 0.012). All patients in group A successfully completed treatment with no side effect. Group B experienced no difference in international prostate symptoms score, peak flow rate and post-void residual whereas group A experienced no difference in peak flow rate, a slight reduction in post-void residual and a decrease in international prostate symptoms score. Most important, reduction in international prostate symptoms score was significantly higher in group A than in group B (-2.0 vs 0, respectively; p = 0.0004). Conclusions. The lycopene/olives vegetation water compound seems to be effective in counteracting lower urinary tract symptoms due to prostatic inflammation
The role of ultrasound and echo-color Doppler in the diagnosis and follow-up of tuberculosis of the transplanted kidney
No full textCombined perianal-intrarectal (PI) lidocaine-prilocaine (LP) cream and lidocaine-ketorolac gel provide better pain relief than combined PI LP cream and periprostatic nerve block during transrectal prostate biopsy.
Full text linkOBJECTIVE:
• To compare the efficacy and safety of combined perianal-intrarectal (PI) lidocaine-prilocaine (LP) cream and lidocaine-ketorolac (LK) gel with combined PI LP cream and periprostatic nerve block (PPNB) in relieving pain during transrectal ultrasonography guided prostate biopsy (TPB).
PATIENTS AND METHODS:
• In all, 200 patients were randomized to receive combined PI LP cream and LK gel (group 1) or combined PI LP cream and PPNB (group 2) before TPB. • The 0-10-point visual analogue scale (VAS) was used for assessing pain at probe insertion and movements (VAS-1), periprostatic infiltration (VAS-2) when applied, and prostate sampling (VAS-3), as well as maximal procedural pain (MPP). • Complications occurring ≤ 20 days after the TPB were recorded.
RESULTS:
• The groups were comparable for patients' age, serum PSA level, prostate volume, and cancer detection rate. • All patients tolerated the procedure well. The two anaesthetic regimens provided almost equal mean VAS-1 (0.33 vs 0.37; P= 0.701) and VAS-3 (0.52 vs 0.51; P= 0.954) scores, but patients in group 2 reported significantly greater MPP scores (0.68 vs 1.53; P < 0.001) as periprostatic infiltration was the most painful part of the procedure (mean VAS-2: 1.33). • Complications rate was similar in the two groups (1% vs 2%; P= 0.38).
CONCLUSIONS:
• The novel combination of PI LP cream and LK gel provided the same probe- and sampling- related pain relief as combined PI LP and PPNB; moreover, by preventing the non-negligible periprostatic infiltration pain, it provided significantly better overall patients' compliance to the procedure. • Being safe and easy to administer, this novel non-infiltrative regimen has the potential to replace infiltrative anaesthesia in relieving pain during TPB
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
