title: DETERMINATION OF KINETIC PARAMETERS AND COMPUTATIONAL SIMULATION OF PERFLUOROPOLYTER (PFPE) EMPLOYED AS A SYNTHETIC LUBRICANT

description: This work aims to determine the kinetic parameters of the thermal decomposition of a lubricating grease based on perfluoropolyether (PFPE) and the computational simulation of this decomposition. The determination of kinetic parameters of thermal decomposition was done by thermal analysis using thermogravimetry (TG) at different heating rates (β) of 10, 15 and 20 ºC min-1. With the TG curves obtained, the kinetic parameters were determined by the kinetics methods of Goldfarb et al. and Duvvuri et al., Flynn-Wall-Ozawa and Kissinger. The activation energy of the thermal decomposition of the PFPE grease in the kinect models ranged from 63.54 to 112.3 kJ mol-1. The results of the thermogravimetry indicated that the PFPE grease is thermally stable up to 300 ºC. A simulation of the thermal decomposition of the PFPE oil base was carried out by molecular dynamics simulation, using LAMMPS (Large-scale Atomic/Molecular Massively Parallel Simulator) in a temperature range of 0 to 3500 K during 50 ps. The value of the activation energy in the simulation was 92 kJ mol-1. The results show that PFPE oil base and PFPE lubricant grease can be used in high-temperature applications.

title: Evaluation of safety, effectiveness and reproducibility of telemedicine for neurosurgical screening

description: ABSTRACT Objective: To ascertain the safety, effectiveness and reproducibility of screening potential neurosurgical patients by means of smartphones. Methods: This is a retrospective and multicentric study. Data were collected from the medical records of patients subjected to real emergency neurosurgical evaluations and compared with assessments by neurosurgeons using smartphones to determine the feasibility of identifying changes in cranial computed tomography scans, potentially serious conditions of patients, and the need for transfer to reference centers. Results: We analyzed 232 cases. The main diagnosis was traumatic brain injury, with 119 cases (51.3%). Of this, 105 (45.3%) patients were discharged immediately after the assessment. The telemedicine evaluators presented 95.69% accuracy in the identification of changes in computed tomography scans, with 0.858 concordance. Accuracy in the identification of severity was 95.26%, with 0.858 concordance. As for procedure, the concordance among evaluators was 0.672, increasing to 100% in cases that required surgical treatment. Conclusion: Our study indicated that the use of telemedicine for screening patients with acute neurological disorders was safe, effective and reproducible. Implementation of the method shows a promising potential to improve the patient's outcome by reducing unnecessary transfers and decreasing the time elapsed until a specialist can be consulted.

title: Tax morals and the Brazilian citizen: an empirical study

description: Abstract This study analyzes the tax morals of the Brazilian citizen, aiming to measure its level, as well as if there is a difference of the tax morals in the sociodemographic characteristics. Tax morale is an important determinant of compliance with tax legislation, so measuring it and evaluate each aspect that determines it allows to strategize and ensure better fiscal conformity. The research period was between May and August 2017, with 679 participants. The questionnaire adapted from the work of Torgler, Schaffner, and MacIntyre (2007), with multiple choice objective questions allowed the collection of data from individuals and was applied indirectly, electronically, validated by the use of the Cronbach’s alpha. The results showed in medium terms a neutral or partially contrary perception of the practice of tax evasion. As far as gender is concerned, the results indicate that women generally have higher tax morals than men. Regarding religion it has been demonstrated that spiritualists have higher tax morals compared to participants from other religions. As for education, the higher the formal education, the higher the tax moral. The results are relevant and meaningful, and help to better understand the challenge of tax compliance, as well as offer elements to insire future research on the subject, considering its theoretical and social relevance, and the fact that it is little studied in Brazil.

title: Drug therapy problems for patients with tuberculosis and HIV/AIDS at a reference hospital

description: ABSTRACT Objective: To determine the frequency of drug therapy problem in the treatment of patients with tuberculosis and HIV/AIDS. Methods: Data were obtained through a cross-sectional study conducted between September 2015 and December 2016 at a reference hospital in infectious diseases in Belo Horizonte (MG), Brazil. Sociodemographic, clinical, behavioral and pharmacotherapeutic variables were evaluated through a semi-structured questionnaire. Drug-related problems of pharmaceutical care were classified using the Pharmacotherapy Workup method. Factors associated with indication, effectiveness, safety and compliance drug therapy problem were assessed through multiple logistic regression. Results: We evaluated 81 patients, and 80% presented at least one drug therapy problem, with indication and adherence drug therapy problem being the most frequent. The factors associated with drug therapy problem were age, marital status, new case, ethnicity, time of HIV diagnosis and time to treat tuberculosis. Conclusion: The frequency of drug therapy problem in coinfected patients was high and the identification of the main drug therapy problem and associated factors may lead the multiprofessional health team to ensure the use of the most indicated, effective, safe and convenient medicines for the patients clinical condition. Tuberculosis and HIV/AIDS coinfected individuals aged over 40 years are more likely to have drug therapy problems during treatment; in that, the most frequente are those that signal toward need of medication for an untreated health condition and non-compliance to treatment. Thus, older patients, unmarried or married, who have treated tuberculosis before, with a shorter time to tuberculosis treatment and longer time to diagnose HIV/AIDS, should receive special attention and be better followed by a multiprofessional health team because they indicate a higher chance of presenting Problems related to the use of non-adherent drugs.

title: Refugees, resettlement experiences and mental health: a systematic review of case studies

description: ABSTRACT Objective In 2017 the number of refugees around the world reached 25.4 million. These people make up one of the most vulnerable populations globally. This study aims to understand the strategies refugees used to cope with the impact on their mental health by the difficult pre- and post-resettlement circumstances they encountered. Methods A systematic review of articles reporting case studies concerning adult refugees’ experiences in the hosting country. The electronic databases searched were: PubMed, The Cochrane Library, PsycINFO, Embase, Scopus and Web of Science. Eligible manuscripts were examined through a narrative synthesis. Results Twenty-two articles fitted the inclusion criteria and four main themes were highlighted: reasons for fleeing; the impact of negative experiences on mental health; supportive experiences and coping strategies; and experiences of mental health treatment. Conclusions Refugees present a significant impact on mental health due to pre- and post-migration experiences. The approach offered to this group and reported as the most effective to deal with such an impact was the multidimensional approach that, besides caring for the psychic aspects, contemplated the cultural context of each one, assisted in housing, employment, financial aid, support with learning the new language and social activities.

title: PHYSIOTHERAPEUTIC APPROACHES AND THE EFFECTS ON INSPIRATORY MUSCLE FORCE IN PATIENTS WITH CHRONIC OBSTRUCTIVE PULMONARY DISEASE IN THE PRE-OPERATIVE PREPARATION FOR ABDOMINAL SURGICAL PROCEDURES

description: ABSTRACT Background: Abdominal disorders can alter respiratory function and increase the morbidity and mortality of patients with chronic obstructive pulmonary disease. Aim: To improve the physiotherapeutic and muscular capacity in chronic obstructive pulmonary muscular inspiration in the preoperative preparation in abdominal surgeries. Method: Retrospective and documentary study using SINPE © , clinical database software of patients with chronic obstructive pulmonary disease and candidates to abdominal operation. The sample consisted of 100 men aged 55-70 years, all with chronic obstructive pulmonary disease who underwent preoperative physiotherapeutic treatment. They were divided into two groups of 50 individuals (group A and group B). In group A the patients were treated with modern mobility techniques for bronchial clearance and the strengthening of the respiratory muscles was performed with IMT ® Threshold. In group B the treatment performed for bronchial obstruction was with classic maneuvers and for the strengthening of the respiratory muscles for flow incentive was used Respiron ® . Results: Both groups obtained improvement in the values of the PiMáx after the different treatments. Group A obtained greater change in the intervals and a more significant increase of the values of the PiMax in relation to the average pre and post-treatment. However, when analyzing the variance and the standard deviation of the samples, group B presented the best results showing more homogeneity. Conclusions: The modern and traditional bronchial clearance techniques associated with inspiratory muscle training were equally effective in gaining inspiratory muscle strength with increased Pmax. In this way, the two can be used in the preoperative preparation of patients with chronic obstructive pulmonary disease and referred to abdominal operations.

title: ORAL HEALTH PROMOTION IN PATIENTS WITH MORBID OBESITY AFTER GASTROPLASTY: A RANDOMIZED CLINICAL TRIAL

description: ABSTRACT Background: The bariatric surgery may have negative repercussions on oral conditions. Aim: To evaluate the impact of oral health educational/preventive program developed with patients submitted to gastroplasties. Method: The sample consisted of 109 patients randomly allocated to two groups: intervention group (IG), where they participated in the oral health promotion program that include multiple educational-preventive approaches; control group (CG), where they received usual care from the bariatric clinic staff, without participation in the program. The oral conditions investigated in the pre-operative and postoperative periods of one month (1M) and six months (6M) were: dental caries, periodontal disease, tooth wear, dental plaque and salivary flow. Results: After bariatric surgery, patients in IG presented: fewer changes in enamel (6M: p=0.004), dentin (6M: p=0.005) and gingival bleeding (6M: p&lt;0.0001), reduction in plaque index (1M, 6M: p&lt;0.0001) and increased salivary flow (6M: p=0.039), when compared with CG. Incipient tooth wear was recorded in both groups (6M: p=0.713). Conclusion: There was a positive impact of the implemented program in the prevention of the main oral health problems in patients who underwent gastroplasties, contributing to their quality of life.

title: Evaluation of Depression and Anxiety in Coronary Artery Bypass Surgery Patients: A Prospective Clinical Study

description: Abstract Objective: The aim of this clinical study is to determine the depression and anxiety levels in coronary artery bypass graft (CABG) surgery patients in the pre and postoperative periods. Methods: This clinical prospective study was done with 65 patients. Beck’s Depression Inventory (BDI) and Beck’s Anxiety Inventory (BAI) tests were performed in patients who had a diagnosis of coronary artery disease and were awaiting CABG surgery. These patients presented characteristic symptoms of anxiety and depression and BDI and BAI tests are important to assess these symptoms. Results: We found out that depression and anxiety levels were higher in the postoperative than in the preoperative period (P&lt;0.001). Both anxiety and depression levels were increased significantly following CABG operation when compared with preoperative levels in all patients. Statistical correlation of depression and anxiety in different ages, genders, and professions were evaluated too, but we did not found a correlation between them (P&gt;0.05). Conclusion: We suggest that good management of the psychological condition of cardiac surgery candidates, as well as post-bypass patients, will improve quality of life and cardiovascular outcomes in these patients.
