EVALUATION OF FACTORS INFLUENCING LEAKAGE IN PRIMARY INTESTINAL ANASTOMOSIS WITHIN A TERTIARY CARE HOSPITAL: A CROSS-SECTIONAL STUDY.
Get PDFBackground
Intestinal anastomosis is a procedure carried out widely for various pathological conditions such as benign tumors, malignant tumors, and inflammatory conditions of a certain part of the intestine. The removal of such a part of the intestine requires the joining of the two other parts of the intestine. Postoperatively the occurrence of a leak in this joint can lead to sepsis and increase the occurrence of mortality and morbidity.
Method
The anastomosis cases of the patients at Sheikh Bhikhari Medical College, Hazaribag are studied retrospectively, and were conducted over two years. 110 cases were reviewed. Clinical and radiological examinations were recorded. The data was statistically analyzed and it was correlated with the occurrence of leakage.
Results
Among the 110 patients participating in the study it was observed that 10 patients had anastomosis leakage. 50% of the patients with leakage had diabetes. more than 70% of them had undergone either emergency surgery, with a duration of more than 2 hours, and required blood transfusion. 30% of the patients with leakage had colo-colic site surgery.
Conclusion
In the present study, it was found that patients who had undergone anastomosis with associated comorbidity, of the colo-colic region, with more than 2 hours of surgery, emergency surgeries, and the required blood transfusion during the surgery had higher chances of development of the anastomosis leakage.
Recommendation
Surgeons should critically analyze the occurrence of anastomosis leakage considering the predisposing risk factors, intraoperative conditions, and site of the surgery
A CROSS-SECTIONAL STUDY ON PREOPERATIVE SURGICAL SITE HAIR REMOVAL FOR ELECTIVE ABDOMINAL SURGERY IN JHARKHAND, INDIA: DOES IT HAVE IMPACT ON SURGICAL SITE INFECTION?
Get PDFBackground
Hair removal at surgical sites, a common preoperative practice to prevent surgical site infections (SSIs) attributed to hair follicles, is often deemed hygienic. However, the literature indicates no significant correlation between hair removal and infection occurrence, making it a questionable ritual for infection prevention.
Method
This study was conducted prospectively at the surgery department of the Shaheed Nirmal Mahto Medical College & Hospital, Dhanbad. The abdominal surgeries conducted in a year were included in this study. Two groups were formed. The first group underwent removal of hair whereas the other group did not undergo the hair removal process. The occurrence of infection was thoroughly evaluated and the data obtained from both the groups were compared. The patients were evaluated during the 7th day, 14th day, and a month of the surgery
Results
In this study of 200 patients (138 males, 62 females) undergoing various surgeries (88 laparoscopic, 112 open), 21 developed surgical site infections (SSIs) during 7, 14, and 30-day follow-ups. Despite higher SSIs in the shaved group, differences in wound scores, pain, suture type, BMI, surgery type, gender, or anesthesia administration were not statistically significant. Clean contaminated surgeries and surgeries under 2 hours showed increased SSIs.
Conclusion
From this study, it is found that when the duration of the surgery is less than 2 hours and the surgery of the clean contaminated category then there is a statistically significant difference in the shaved and unshaved group considering the number of SSI. Otherwise shaving does not cause any alteration in the number of SSIs.
Recommendation
Shaving should be considered preoperatively if its potential benefits outweigh the occurrence of surgical site infection. Also in case of clean contaminated open surgeries, a rigorous prophylaxis of antibiotics should be given
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
