Performance assessment and analysis of development and operations based automation tools for source code management

Development and operations (DevOps), an accretion of automation tools, efficiently reaches the goals of software development, test, release, and delivery in terms of optimization, speed and quality. Diverse set of alternative automation tools exist for different phases of software development, for which DevOps adopts several selection criteria to choose the best tool. This research paper represents the performance evaluation and analysis of automation tools employed in the coding phase of DevOps culture. We have taken most commonly followed source code management tools-BitBucket, GitHub actions, and GitLab into consideration. Current work assesses and analyzes their performance based on DevOps evaluation criteria that too are categorized into different dimensions. For the purpose of performance evaluation, weightage and overall score is assigned to these criteria based on existing renowned literature and industrial case study of TekMentors Pvt Ltd. On the ground of performance outcome, the tool with the highest overall score is realized as the best source code automation tool. This performance analysis or measure will be a great benefit to our young researchers/students to gain an understanding of the modus operandi of DevOps culture, particularly source code automation tools. As a part of future research, other dimensions of selection criteria can also be considered for evaluation purposes

Effectiveness of oral health education versus nicotine replacement therapy for tobacco cessation- a parallel randomized clinical trial

Background: India has millions of tobacco users. It is the leading cause of deaths due to oral cancer and hence needs effective strategies to curb it. Hence the aim of present study was to evaluate and compare the effectiveness of Oral Health Education (OHE) and Nicotine Replacement Therapy (NRT) in tobacco cessation. Material and Methods: The clinical trial consisted of Manohar Lal Kapoor (MLK) factory workers (n= 40) giving history of tobacco consumption (smoking/smokeless) within past 30 days. They were randomized into OHE (n=20) and NRT (n=20) groups. Baseline evaluation (demographic, smoking/ smokeless behaviour) was done. Fagerstrom test was used for Nicotine Dependence (FTND) and to assess nicotine addiction level. Follow up was done at an interval of 1week, 2 weeks, 1 month, 2 months and 3 months to assess the reduction in the mean FTND score. “Nano-CheckTM Rapid Nicotine test” was used for the qualitative detection of cotinine in human urine. Appropriate statistical analysis was performed (Paired and Unpaired t test). Results: In both OHE and NRT group there was a significant reduction ( p < 0.00001) in mean Fagerstrom score at every follow up but when both the groups were compared mean Fagerstrom score reduction was more in NRT than OHE at all time interval though it was not statistically significant ( p >0.05). Conclusions: NRT is better than OHE when both the groups were compared. However, it was found that any intervention given to tobacco users either NRT or OHE is helpful for the patients in the process of quitting tobacc

Juvenile Nasopharyngeal Angiofibroma: Case report with review on role of imaging in diagnosis

Juvenile nasopharyngeal angiofibroma is a locally aggressive benign vascular neoplasm, composed of vasogenic and myofibroblastic elements, accounts for 0.05-0.5% of all the head and neck neoplasms. There are very few case reports of nasopharyngeal angiofibroma involving the oral cavity; we report a case involving both the maxilla and mandible in a 17-year-old patient who reported with a large firm swelling on right side of face with recurrent epistaxis and headache. Magnetic resonance angiography revealed a large lobulated enhancing soft tissue mass, which was hypointense on T1-weighted image and heterogeneously hyperintense on T2-weighted image causing expansion of pterygopalatine fossa and sphenopalatine foramen with extension into the sphenoid sinus, ethmoid air cells, right nasal cavity, right infratemporal fossa and right maxillary sinus with remodeling of right zygomatic arch and part of body and ramus of mandible. It was supplied by the right external carotid artery. Patient was referred to the department of neurosurgery for further management. The diagnosis at an early stage is important because it is associated with high risk of morbidity, but advances in imaging, and surgical methods of treatment have changed the sites associated with high risk of morbidity

Absent right coronary artery: A case of single coronary artery or congenital ostial atresia?

Atresia of the right coronary artery ostium is a rare anatomic variant of the coronary circulation. It is often difficult to differentiate from single coronary artery. Its presence unassociated with any other anomaly has never been described in an adult individual. We report this unusual anomaly and discuss its anatomical and pathophysiological significance and possible ways to differentiate from single coronary artery

Indications, timing and techniques of radical pericardiectomy via modified left anterolateral thoracotomy (ukc's modification) and total pericardiectomy via median sternotomy (holman and willett) without cardiopulmonary bypass

Background: Patients with constrictive pericarditis can be treated by pericardiectomy by either left anterolateral thoracotomy or median sternotomy. The terms “radical,” “total,” “extensive,” “complete,” “subtotal,” “adequate,” “near-total,” and partial pericardiectomy have been used often without much clarity. We describe our experience with a radical pericardiectomy technique via modified left anterolateral thoracotomy and compare the same to total pericardiectomy via median sternotomy. Methods: In this study, 67 (54.9%) patients underwent radical pericardiectomy via modified left anterolateral thoracotomy (Group I), and 55 (45.1%) patients underwent total pericardiectomy via median sternotomy (Group II). Results: The operative mortalities were 2.9% and 7.2% for the radical and total pericardiectomy groups, respectively. The time taken for normalization to Class I/II in Groups I and II was 30 ± 11 and 36 ± 14 days, respectively (P = 0.009). Surgical techniques did not affect the outcome of atrial fibrillation (P = 0. 77). Reoperation was not required for any patient. The radical pericardiectomy was also associated with less postoperative low cardiac output state as compared to patients undergoing total pericardiectomy (P < 0.001). There was no difference in mean duration of hospitalization; however, the radical pericardiectomy group achieved the New York Heart Association I and II Status quicker than the total pericardiectomy group (P = 0. 009). Conclusions: We conclude that using several technical modifications of pericardial excision, it is possible to achieve radical pericardiectomy via modified left anterolateral thoracotomy, particularly removing the constricting pericardium over the anterolateral, diaphragmatic surfaces of left ventricle and the anterior and diaphragmatic surfaces of the right ventricle until the right atrioventricular groove without using cardiopulmonary bypass in the great majority of patients undergoing pericardiectomy for chronic constrictive pericarditis. Although the surgical approach for pericardiectomy is based on surgeon's preference, left anterolateral thoracotomy is the preferred and noncontroversial approach in the setting of purulent pericarditis and effusive constrictive pericarditis to prevent sternal infection. We recommend median sternotomy approach with or without cardiopulmonary bypass, in the setting of calcific pericardial patches, pericardial masses, reoperations, and calcific pericardial “cocoon” and for those with predominant right-sided and annular involvement

Short-term prognostic value of perioperative coronary sinus-derived-serum cardiac troponin-I, creatine kinase-MB, lactate, pyruvate, and lactate-pyruvate ratio in adult patients undergoing open heart surgery

Objectives: To investigate the release pattern of different cardiac metabolites and biomarkers directly from the coronary sinus (CS) and to establish the diagnostic discrimination limits of each marker protein and metabolites to evaluate perioperative myocardial injury in patients undergoing cardiac surgery under cardiopulmonary bypass (CPB). Patients and Methods: Sixty-eight patients undergoing first mitral and/or aortic valve replacements with/without coronary artery bypass grafting and Bentall procedure under CPB and blood cardioplegic arrest were studied. All cardiac metabolites and biomarkers were measured in serial CS-derived blood samples at pre-CPB, immediate post aortic declamping, 10 minutes post-CPB and 12 hrs post-CPB. Results: Receiver operating characteristic curve analysis of cardiac biomarkers indicated lactate-pyruvate ratio as the superior diagnostic discriminator of myocardial injury with an optimal "cut-off" value >10.8 immediately after aortic declamping (AUC, 0.92; 95% CI: 0.85-0.98). Lactate was the second best diagnostic discriminator of myocardial injury with an optimal "cut-off" value >2mmol/l at immediately after aortic declamping (AUC, 0.89; 95% CI: 0.80-0.96). Cardiac troponin-I was the third best diagnostic discriminator of myocardial injury with an optimal "cut-off" value >2.1ng/ml at immediately after aortic declamping (AUC, 0.88; 95% CI: 0.80-0.95). Creatine kinase-MB was the fourth best diagnostic discriminator of myocardial injury with an optimal "cut-off" value >58 log units/ml prior to decanulation (AUC, 0.85; 95% CI: 0.78-0.94). Conclusions: Measurable cardiac damage exists in all patients undergoing cardiac surgery under cardioplegic arrest. The degree of myocardial injury is more in patients with poor ventricular function and those requiring longer aortic clamp time. CS-derived lactate-pyruvate ratio, lactate, cTn-I served as superior diagnostic discriminators of peri-operative myocardial damage
