Dietary Protein Supplementation Helps in Muscle Thickness Regain after Abdominal Wall Reconstruction for Incisional Hernia
No full textA modern approach to incisional hernia is oriented toward midline restoration to re-establish abdominal wall physiology and to restore muscular strength. A high-protein diet has been demonstrated to improve muscle function and mass. The aim of this prospective study was to evaluate the effect of a high-protein diet on abdominal muscle remodeling in patients submitted to abdominal wall reconstruction (AWR). Forty-five patients submitted to elective AWR were prospectively divided into two groups depending on pre- and postoperative daily protein assumption: Group A patients were submitted to a standard 2300 kcal diet with 103 g of protein intake (males) and 1800 kcal diet with 80 g of protein intake (females) starting one month before surgery and lasting for three months postoperatively; Group B patients were submitted to the same dietary regimen plus 34 g of purified proteins daily. Patients underwent ultrasound scan preoperatively and three and six months after surgery, to evaluate the widest thickness of the rectus abdominis muscle on the transverse umbilical line. Three patients reporting hernia recurrence were excluded. No significant difference among the two groups in muscle thickness growth after surgery was observed at three months after surgery, even if a favorable trend in Group B was noted (10% vs 19%, P = not significant). At six months after surgery, Group B patients showed a significant difference in muscle thickening (13% vs 32%, P < 0.05 ). The study demonstrates a positive effect of a protein diet on the rectus abdominis muscle thickening after AWR. Further studies are needed

No full textRIASSUNTO. Background. Il fenomeno degli infortuni
durante il percorso universitario rappresenta un problema
di salute pubblica. Gli studenti trascorrono molto tempo
all’università e nelle strutture per i tirocini. Questo li porta
ad essere esposti a rischi di tipo biologico, chimico, ergonomico,
potenzialmente causa di infortuni, o malattie professionali.
Obiettivo. L’obiettivo del presente studio è quello di descrivere
gli infortuni occorsi agli studenti della Sapienza di Roma
durante il periodo 2010-2015.
Materiali e Metodi. Studio di natura retrospettiva, condotto
su una coorte di studenti dell’Università Sapienza frequentanti
negli anni dal 2010 al 2015. Come fonte di dati si è utilizzato
il registro degli infortuni denunciati dagli studenti stessi,
gestito ed aggiornato dalla Sede del Rettorato della Sapienza
di Roma.
Risultati. Nel periodo considerato sono stati registrati infortuni
in 791 studenti, prevalentemente di genere femminile (71.8%).
Gli studenti in scienze infermieristiche sono i più colpiti
(92.8%), a seguire vi sono gli studenti di medicina (5.7%)
e per finire studenti di altre facoltà (1.5%). Le ferite da punta
sono le più frequenti (n=462) rappresentando il 58.4 % del
totale e si verificano principalmente a livello del polso e della
mano (n=380); il secondo tipo di infortunio più frequente è il
contatto con liquido biologico (n=159) seguito dalle contusioni
(n=72), la sede più interessata da è la testa e il volto (n=81;
n=23). Le contusioni interessano spesso anche regioni multiple
(n=17). In minor numero si presentano anche le distorsioni
(n=55), e fratture (n=26) le prime più frequenti a caviglia
e piede (25.5%), le seconde più frequenti a polso e mano
(34.6%) L’incidenza di infortuni va dallo 0.079% del 2011
allo 0.161 % del 2012.
Conclusioni. Emerge la necessità di progettare misure per una
formazione specifica più intensa sugli studenti con particolare
attenzione agli studenti in infermieristica, in quanto classe
maggiormente esposta, al fine di ridurre il fenomeno
infortunistico. Particolare attenzione andrebbe posta alla
gestione in sicurezza di oggetti appuntiti e taglienti. Utile sarebbe
l’inserimento nel percorso di studio di insegnamenti mirati
alla sicurezza e ad una maggiore consapevolezza del rischio.Background. The phenomenon of accidents during the university course is a public health problem. Students spend a lot of time at university and in structure for training. This this leads them to be exposed to biological, chemical and ergonomic risk of accidents or occupational diseases. Aim. The aim of this study is to describe accidents that occurred to students of Sapienza University in Rome during the period 2010-2015. Materials and Methods. Retrospective study conducted on a cohort of students from Sapienza University in the years 2010-2015. As a source of data was used register of accidents reported by the students. Results. During the period considered, injuries were recorded in 791 students, mainly female (71.8%). Nursing students were the most affected (92.8%), followed by medical students (5.7%) and finally students of other faculties (1.5%). Point wounds were the most frequent (n=462) representing 58.4% of the total and occur mainly at the wrist and hand (n=380); the second most frequent type of injury is contact with biological liquid (n=159) followed by contusions (n=72), the most affected site in this case are the head and the face (n=81; n=23). Contusions often also involve multiple regions (n=17). In lesser numbers there are also the distortions (n=55), and fractures (n=26) the most frequent first ankle and foot (25.5%), the second most frequent wrist and hand (34.6%) The incidence of accidents ranged from 0.079% in 2011 to 0.161% in 2012. Conclusion. There is a need to design measures for more intensive specific training on biomedical students, especially nursing students, as the most exposed category, in order to reduce the accident phenomenon. Particular attention should be paid to the safe handling of sharp objects. It would be beneficial to include in the course of teaching lessons aimed at security and greater awareness of the risk
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
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
