Evaluation of Quality of Life after Radical Gastric Cancer Operations
The goal of study: to evaluate the quality of life after radical surgical treatment of gastric cancer Research objectives: 1. Compare the quality of life in patients after radical surgical treatment of gastric cancer when total or subtotal gastrectomy is performed. 2. Compare the quality of life after surgical treatment of gastric cancer when adjuvant chemotherapy is used or not used. 3. Search for differences between quality of life scales in patients after radical surgery of gastric cancer depending on age, sex and stage of the disease. Object of research: 42 patients after radical operations of gastric cancer. Results: 1. Patients after subtotal gastrectomy have better quality of life than patients after total gastrectomy, but the results are statistically insignificant. 2. Patients who had adjuvant chemotherapy treatment have better quality of life than patients who hadn‘t, but the results are statistically insignificant. 3. The differences of quality of life in radically operated patients of different stage of cancer were statistically insignificant. Younger patients have better quality of life, but the differences are statistically insignificant. Females reported better quality of life in symptom (p=0.030) and function (p=0.036) scales compared with males. The results were statistically significant. Conclusions: The differences of quality of life based on stage of stomach cancer, adjuvant chemoterapy, type of operation, age of patients were statistically insignificant. Females had statistically significant better quality of life based on the results of function scales (p=0.036) and symptom scales (p=0.030)
Postoperative Period Features after Inguinal and Pelvic Lymphadenectomy
Salvijus Žukauskas ‘‘Postoperative period features after inguinal and pelvic lymphadenectomy’’ The aim of the study: evaluate postoperative period features after inguinal and pelvic lymphadenectomy. Goals of the research: 1. Link the influence of age and gender to the postoperative period after performed inguinal and pelvic lymphadenectomy. 2. Access the volume of surgical intervention and type of cancer to the postoperative period. 3. Evaluate postoperative complications according to Clavien – Dindo classification. Research subjects and methods: A retrospective analysis of 51 patients’ medical records hospitalized in LUHSH KC branch Hospital of Oncology Clinic of Surgery who have had inguinal and pelvic lymphadenectomy during a 2015 – 2019 year period. Data analysis was performed using SPSS 26.0. Statistical significance was evaluated with chi square (χ²) criterion, Pearson correlation was used. Results of the study: the mean patient age was 69 years. Older patients had a longer postoperative hospitalization period (p=0,001) and a greater complication rate (p=0,018). Women mean age was bigger (p=0,024). Trend was observed that women also had longer postoperative hospitalization period (p=0,077). There was no statistical significance between the type of cancer and age or postoperative period. Complication rate was 54,9 % in general. Although not statistically significant, there was a greater complication rate (p=0,138) and a longer wound secretion period (p=0,105) observed after major surgical approach (inguinal and pelvic lymph node dissection). According to Clavien – Dindo classification, patients with II and III grade complications had a greater postoperative hospitalization period (p=0,022) which was mostly observed for older patients (p=0,05). Conclusions of the study: after inguinal and pelvic lymphadenectomy, the age of older patients influenced the longer postoperative hospitalization period and greater rate of complications. There were no differences observed between gender or cancer type and postoperative period. It was observed that after major surgical approach (inguinal and pelvic and both side inguinal lymph node dissection) there was a longer wound secretion period and a greater complication rate but the results were not statistically significant
The effectiveness of adjuvant therapy after curative gastrectomy for gastric cancer
Gastric cancer is the fifth most common cancer and the second leading cause of cancer-related death worldwide. The 5-year survival rate of these patients is approx. 25. Adjuvant chemotherapy is frequently used for treatment, despite the fact that many randomized studies failed to demonstrate a better patient survival. The high rate of recurrence, even in patients undergoing state-of-the art curative resection, suggests that effective adjuvant chemoradiation and chemotherapy might indeed be an attractive concept to improve the overall outcomes of patients with gastric cancer. The aim of this study was to evaluate the effectiveness of the adjuvant therapy after curative resection with D2 lymphadenectomy for gastric cancer and determine its role in the treatment of cancer patients. The goals of this study were: 1. To compare the survival of patients receiving adjuvant chemoradiation or adjuvant chemotherapy after the curative resection with D2 lymphadenectomy for gastric cancer. 2. To evaluate the toxicity of the adjuvant chemoradiation after the curative resection with D2 lymphadenectomy for gastric cancer and to compare it with the toxicity caused by adjuvant chemotherapy with 5- Fluorouracil and Leucovorin. 3. To assess the toxicity of the early postoperative intraperitoneal chemotherapy and compare its effectiveness with the combined intraperitoneal chemotherapy and adjuvant chemoradiation therapy. 4. To compare the quality of life after the total and subtotal gastrectomy with D2 lymphadenectomy with adjuvant chemoradiotation or adjuvant chemotherapy accordingly
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
We 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
