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
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
Videourodynamic evaluation of intracorporeally reconstructed orthotopic U-shaped ileal neobladders
No full textOBJECTIVE:
To study the functional outcomes of 30 patients who had previously undergone laparoscopic radical cystectomy with intracorporeal orthotopic ileal neobladder reconstruction using videourodynamic (VUDM) assessment 180 days postoperatively.
METHODS:
Between November 2010 and December 2013, 30 male patients had undergone laparoscopic radical cystectomy with bilateral standard pelvic lymphadenectomy and pure laparoscopic orthotopic ileal U-shaped neobladder diversion. The demographic data were as follows: median age, 67 years (range, 62-79); body mass index, 22.3 kg/m(2) (range, 16-26.1 kg/m(2)); and mean American Society of Anesthesiologists score 2.2 (range, 1-3). Functional outcomes were assessed performing a standard VUDM study combined with perineal floor electromyography 180 days postoperatively.
RESULTS:
VUDM evaluations showed good functional outcomes of the reservoirs. Mean maximal neobladder capacity was 287 mL (range, 210-335 mL). Residual peristaltic activity was observed in all the individuals evaluated; however, only 9 of 30 individuals (30%) displayed severe peristaltic activity. Six of these 9 individuals (66.6%) experienced urinary leakage during these contractions. Mean postvoid residual volume was 44 mL (range, 0-105 mL), and peak flow rate was 13.9 mL/s (range, 9.7-29.2 mL/s). The Valsalva maneuver was positive in 5 of 30 subjects (17%). Bladder morphology assessed during contrast cystography showed the desired U-shape in all cases. Ureteral reflux was observed in 7 of 30 individuals (23.3%).
CONCLUSION:
Based on VUDM, our study shows that U-shaped ileal neobladders achieved by a totally laparoscopic approach obtained good functional outcomes. These findings support the evidence that a minimally invasive approach does not impose technical limitations that negatively impact the surgical results
Systematic differences between BNP immunoassays: Comparison of methods using standard protocols and quality control materials
Full text linkBackground: Recent studies suggested that there are marked systematic differences among BNP immunoassays.
In this study we compared the BNP data and clinical results obtained with different immunoassays, including a
new method (ST-AIA-PACK, TOSOH Corporation).
Methods: BNP was measured on plasma-EDTA samples of healthy subjects (HS, n = 126) and patients with
heart failure (HF, n = 31 NYHA I, II; n = 46 NYHA III, IV) using the ST-AIA-PACK and the Triage Biosite
(Beckman Coulter) methods. Control samples distributed in the CardioOrmoCheck external quality assessment
were also measured with TOSOH and the most used BNP immunoassays in Italy.
Results: TOSOH method showed a good correlation (R = 0.976; n = 327) but a mean bias (−46.9%) compared
to Triage Biosite. On the base of the results obtained in 10 samples of the CardioOrmoCheck study, TOSOH
method showed a strict agreementwith ADVIA Centaur, while it underestimated BNP in comparisonwith Triage
(−52.5%) and ARCHITECT methods (−39.4%). The agreement of ST-AIA-PACK and Triage Biosite methods for
classification of HF patients was tested using 100 ng/L of BNP; the positive agreement between methods was
65%, overall agreement was 73%.
Conclusions: Our results confirm that there are marked differences in measured values among commercial
methods for BNP assay

No full textA prospective study to evaluate the efficacy of cistiquer in improving lower urinary tract symptoms in females with urethral syndrome.
No full textThe aim of the study was to compare Cistiquer, a new phytotherapeutic product developed for chronic bladder inflammatory diseases, and intra--vesical administration of gentamicin plus betametasone, in females with urethral syndrome. Between september 2013 and may 2014, 60 women with urethral syndrome and trigonitis were incuded in this study. Patients were randomly assigned to treatment with intra--vesicle administration of betametasone 8 mg plus gentamicin 80 mg (group A), and oral administration of Cistiquer (group B) for 7 weeks. Before and after the therapeutic protocol, symptoms were assessed by three days voiding diary, the overactive bladder questionnaire short form and a ten points visual anagogic scale adopted to assess the micturition discomfort. Histologic findings were assessed by the examination of specimens obtained by cold bladder biopsies of the bladder trigone at baseline in all the subjects. The two groups had significant and comparable symptoms improvement. However, the score obtained from the visual analogic scale decreased significantly only in the group submitted to oral therapy. Furthermore, in the group treated with endovesical approach, higher drop out rate and higher incidence of urinary infection were observed. Patients with urethral syndrome and trigonitis improved symptoms either with oral therapy with Cistiquer and with intra--vesical administration of gentamicin plus betametasone. However, treatment adherence resulted higher for patients treated by oral therapy and rate of adverse events resulted higher for those submitted to endovesical treatment
