Psychological factors in reducing excess body weight after bariatric surgery

BACKGROUND: The relevance of the problem of obesity today is not in doubt. One of the most effective treatments today is bariatric surgery. At the same time, the effectiveness of the surgical method is not always predictable, as it is influenced by various factors, including the psychological state of the patient. AIM: To study the psychological characteristics of patients with obesity before and after surgical (bariatric) treatment and to establish the relationship with weight loss. MATERIALS AND METHOD: The study involved 32 patients with morbid obesity before and a year after laparoscopic longitudinal resection of the stomach with an initial body mass index of 45.36 (+54.90; -33.00). Questionnaire used: Symptom Check List-90-R (L.R. Derogatis). Statistical data processing was carried out using the statistical programming language R. RESULTS: The presence or increase in the level of phobic anxiety (a persistent reaction of fear to certain people, situations and places) and psychotism (isolation, interpersonal isolation, avoidance) in a patient can have a negative impact on the success of weight loss in the postoperative period. CONCLUSIONS. The psychological factors affecting the prognosis of weight loss after bariatric surgery have been identified. Psychological testing and determining the patient’s psychotype can be predictive in improving the outcome of surgical treatment of obesity

DATA MINING AND STATISTICS METHODS USAGE FOR ADVANCED TRAINING COURSES QUALITY MEASUREMENT: CASE STUDY

In the article we consider a case of the analysis of the data connected with educational statistics, namely – result of professional development courses students survey with specialized software usage. Need for expanded statistical results processing, the scheme of carrying out the analysis is shown. Conclusions on a studied case are presented

Data Mining and Statistics Methods for Advanced Training Course Quality Measurement: Case Study

Advanced training courses in the energetics field is a very important part of human reliability growth. In the words of S.E. Magid, chief of Technical Educational systems in Energy Technologies, UNESCO department: “The number of forced outages due to failures of equipment on the power stations -30 %. The share of operational personnel fault in these infringements makes considerable size (to 15%). As a whole in the Russian Open Society ‘United Power Systems’ the infringements percentage because of the personnel from infringements total makes 2%. At the same time, on power stations this quantity makes 18%. In power supply systems of Siberia the relative quantity of infringements because of the personnel reaches 50%.” [1]

Neutrophils mediate pulmonary artery thrombosis in situ

Pulmonary embolism is a life-threatening condition, which can result in respiratory insufficiency and death. Blood clots occluding branches of the pulmonary artery (PA) are traditionally considered to originate from thrombi in deep veins (usually in legs). However, growing evidence suggests that occlusion of the vessels in the lungs can develop without preceding deep vein thrombosis (DVT). In this work, we used an inferior vena cava (IVC) complete ligation model of DVT in Wistar rats to explore the possibility and mechanisms of PA thrombosis under the conditions where all routes of thrombotic mass migration from peripheral veins are blocked. We demonstrate that rats both with normal and reduced neutrophil counts developed thrombi in the IVC, although, neutropenia caused a substantial decrease in thrombus size and a shift from fresh fibrin toward mature fibrin and connective tissue inside the thrombus. Massive fibrin deposition was found in the PA branches in the majority of DVT rats with normal neutrophil counts, but in none of the neutropenic animals. Neutrophil ablation also abolished macroscopic signs of lung damage. Altogether, the results demonstrate that thrombi in the lung vasculature can form in situ by mechanisms that require local neutrophil recruitment taking place in the DVT setting

Hydrogen Accumulation and Distribution in Pipeline Steel in Intensified Corrosion Conditions

Hydrogen accumulation and distribution in pipeline steel under conditions of enhanced corrosion has been studied. The XRD analysis, optical spectrometry and uniaxial tension tests reveal that the corrosion environment affects the parameters of the inner and outer surface of the steel pipeline as well as the steel pipeline bulk. The steel surface becomes saturated with hydrogen released as a reaction product during insignificant methane dissociation. Measurements of the adsorbed hydrogen concentration throughout the steel pipe bulk were carried out. The pendulum impact testing of Charpy specimens was performed at room temperature in compliance with national standards. The mechanical properties of the steel specimens were found to be considerably lower, and analogous to the properties values caused by hydrogen embrittlement
