title: Impact of Complications of Myocardial Revascularization Surgery on Expenses During Hospital Stay

description: Abstract Background: Coronary artery bypass grafting (CABG) is an important treatment option for obstructive coronary artery disease, but it represents a high expense for paying sources. The complications of CABG impose an additional expense to the procedure that is not yet clearly established. Objective: To determine the economic impact of postoperative complications of CABG during hospitalization in a hospital of the unified health system (SUS). Methods: This is an observational study involving 240 patients undergoing isolated CABG in a reference hospital in cardiology in 2013. Patients aged over 30 years with proven coronary artery disease and indication to perform CRVM were included. Patients who performed CRVM associated with other procedures were excluded. Results: The average cost of hospitalization was R$ 22,647.24 (SD = R$ 28,105.66). In 97 patients who presented some complication the average cost was R$ 35,400.28 (SD = R$ 40,509.47), and in the 143 patients without complications the average cost was R$ 13,996.57 (SD = R$ 5,800.61) (p &lt; 0.001). Expenditures ranged from R$ 17,344.37 in patients with one complication up to R$ 104,596.52 in patients with five complications (p &lt; 0.001). Conclusions: The occurrence of complications during hospitalization for CABG significantly increases the costs of the procedure, but the magnitude of this increase depends on the type of complication developed, and higher expenses related to cardiovascular complications, infections and bleeding. With this information, managers can improve the allocation of resources to health.

title: Correlation between Exercise Stress Test and Echocardiographic Parameters in Elderly Individuals

description: Abstract Background: Maximum oxygen consumption (VO2 max) in healthy individuals decreases approximately 10% per decade of life, and such decrease is more pronounced after the seventh decade. Objectives: To assess functional capacity of individuals aged 75 years or older, submitted to ergometric test and transthoracic echocardiogram exam, by means of metabolic equivalent (MET) and VO2 max measurements. Methods: A total of 381 patients (205 women; 79 ± 3.7 years) were evaluated. Exclusion criteria were: presence of left ventricular (LV) systolic dysfunction, LV diastolic dysfunction grade II and III, significant valve disease, or coronary artery disease with systolic LV dysfunction or dilatation. Associations between quantitative variables were analyzed by Pearson and Spearman correlation coefficients, and comparisons of quantitative data by Student's t-test for independent samples. Results: Increasing age was associated with a progressive decrease in the distance covered (p = 0.021), in the expected increase in HR (p &lt; 0.001), in VO2 max (p &lt; 0.001), and METs (p &lt; 0.001) in both genders. There was no correlation of exercise test parameters with the echocardiographic parameters. Conclusions: Relatively healthy older individuals, with global systolic and diastolic functions of the left ventricle preserved, presented a progressive decrease in their functional capacity due to their natural aging process, comorbidities related to their age range and physical deconditioning.

title: C-reactive Protein is a Predictor of Mortality in ST-segment Elevation Acute Myocardial Infarction

description: Abstract Background: Inflammation is a major component of the response to tissue injury caused by myocardial infarction. High-sensitivity C-reactive protein (hs-CRP) levels might be a simple marker of the severity of this inflammatory response, providing prognostic information. Objective: To associate hs-CRP level on admission and other clinical characteristics with in-hospital mortality of patients with acute ST-segment elevation myocardial infarction (STEMI). Methods: A retrospective cohort study of patients admitted with STEMI was carried out. Patients were analyzed regarding clinical characteristics, reperfusion therapy, hs-CRP on admission and outcomes. Continuous variables were analyzed by non-parametric Mann-Whitney U test and categorical variables by chi-square test. A p value of &lt; 0.05 was considered statistically significant. Results: Of the 118 patients analyzed, 20 died during hospitalization. Higher levels of hs-CRP (p = 0.001) and older ages (p = 0.003) were observed among those patients who died. Logistic regression showed that a one unit increase in hs-CRP increased the risk of death by 15% (p = 0.0017), after adjustment for established risk factors. Similarly, each one-year increase in age increases the risk of death by 6.6% (p = 0.003). Conclusion: Our results demonstrate a strong association between hs-CRP obtained on admission and in-hospital mortality after STEMI. It suggests that hs-CRP can be a marker of inflammatory response to myocardial ischemia, providing prognostic information regarding the risk of death.

title: Determinants of the Distance Covered During a Six-Minute Walk Test in Patients with Chronic Heart Failure

description: Abstract Background: The evaluation of the functional capacity of patients with chronic heart failure (HF) by means of the distance covered in the six-minute walk test (6MWT) has assumed great importance, since the 6MWD is a predictor of mortality and hospitalization in this population, however the determinants of better distance traveled in patients with HF are little explored, especially in the Brazilian population. Objective: To evaluate the determinants of 6MWD in patients with chronic HF. Methods: A cross-sectional study was performed with 81 HF patients in outpatient treatment. 6MWD was used as the outcome variable and sociodemographic, clinical, physical-functional and emotional data were submitted to multiple regression analysis using the stepwise method with a significance level of 5%. Results: Mean age of participants was 56.71 years; the 6MWD showed a bivariate correlation with age (r = -0.27, p = 0.01), maximal inspiratory pressure (r = 0.42, p &lt; 0.01), maximal expiratory pressure (r = 0.36, p &lt; 0.01), handgrip strength (r = 0.38, p &lt; 0.01), Borg scale (-0.22, p = 0.04), Charlson index (r = -0.25, p = 0.02) and modified Medical Research Council (mMRC) dyspnea scale (r = -0.42, p &lt; 0.01). In the multivariate analysis, the variables gender (p = 0.001), age (0.004), forced vital capacity (FVC) (p = 0.016) and mMRC (p = 0.001) simultaneously explained 37% of variance in the 6MWD. Conclusion: Higher levels of dyspnea on daily life activities, female sex, older age and lower forced vital capacity are determinants of a shorter 6MWD in patients with chronic HF.

title: Enriched semantic markup for postgraduate programs in Latin America

description: ABSTRACT Enriched semantic markup provides meaning to content and allows interoperability between machines, encouraging the visualization of information for users, such as the use of rich snippets, which expand the information provided by search engines. The objective was to analyze and enrich semantically the contents of the graduate programs delivered to the users, so that they are interoperable and contribute to the community through the reuse and proposal of extension of a new entity. The methodology used was descriptive based on the compilation and systematization of qualitative and quantitative information, analysis and characterization of the contents that currently contain the studied web pages and the Schema.org vocabulary. As result, a content semantically enriched markup proposal is presented for the postgraduate programs offered by some Latin American universities contained in a new entity named ProgramaPosgrado, based on the vocabulary of Schema.org. It was concluded that enriched semantic markup using rich snippets is a true Semantic Web application that adds visibility and interoperability to Web content, verifying that Schema.org is a vocabulary that can be extended for use in different fields.

title: SPORTS ACTIVITY AND HIP, KNEE, SHOULDER AND INTERVERTEBRAL DISC ARTHROPLASTIES

description: ABSTRACT The success of joint replacement surgery has been responsible for raising patients' expectations regarding the procedure. Many of these procedures are currently designed not only to relive the pain caused by arthrosis, but also to enable patients to achieve functional recovery and to engage in some degree of physical activity and sports. However, as physical exercise causes an increase in forces exercised through the articular prosthesis, it can be an important risk factor for its early failure. Scientific literature on sports after arthroplasty is limited to small-scale retrospective studies with short-term follow-up, which are mostly insufficient to evaluate articular prosthesis durability. This article presents a review of the literature on sports in the context of hip, knee, shoulder and intervertebral disc arthroplasty, and puts forward general recommendations based on the current scientific evidence. Systematic Review, Level of Evidence III.

title: ORTHOPEDIC INJURIES IN MEN'S PROFESSIONAL SOCCER IN BRAZIL: PROSPECTIVE COMPARISON OF TWO CONSECUTIVE SEASONS 2017/2016

description: ABSTRACT Purpose: The purpose is to compare the incidence and characteristics of injuries sustained in two consecutive seasons of the São Paulo State Football Championship. Methods: Prospective study performed using an electronic form previously developed by the Medical Committee of the São Paulo State Football Federation, sent to the physicians responsible for the tournament's series A1 and A2 teams, after each round. Results: 17.63 injuries sustained per 1000 hours of matches in the A1 series and 14.91 injuries sustained per 1000 hours of matches in the A2 series. Incidence of injuries per 1000 hours of matches decreased from 24.16 to 17.63 in the A1 series (p&lt;0.037) and from 19.10 to 14.01 in the A2 series (p&lt;0.064). External defenders suffered most injuries, while muscular injuries were most common and lower limbs, the most affected areas. Most injuries occurred between 30 and 45 minutes of the match and only 11.9% of the injuries required surgery. Conclusions: Prevalence and frequency of injuries decreased between seasons. Most injuries were sustained in the lower limbs; strains were the most common injuries, followed by strains and contusions; MRIs were the most frequently requested exams and most injuries were classified as moderate (8-28 days). Level of evidence III, Cross-Sectional Study.

title: ASSESSMENT OF THE RESULTS OF ACCESSORY TO SUPRASCAPULAR NERVE TRANSFER

description: ABSTRACT Objective: Nerve transfers are an alternative in the reconstruction of traumatic brachial plexus injuries. In this study, we report the results of branchial plexus reconstruction using accessory to suprascapular nerve transfer. Methods: Thirty-three patients with traumatic brachial plexus injuries underwent surgical reconstruction with accessory to suprascapular nerve transfers. The patients were divided into groups in which surgery was performed either within 6 months after the injury or more than 6 months after the injury. Results were assessed using the Constant score. Results: There was no significant difference between the groups with respect to the Constant score. Conclusion: Accessory to suprascapular nerve transfer was not an efficient method for recovering active ROM or strength in the shoulder. However, it effectively improved pain control and shoulder stability. Level of evidence II, Retrospective Study.

title: FACTORS RELATED TO AMPUTATION LEVEL AND WOUND HEALING IN DIABETIC PATIENTS

description: ABSTRACT Objective: There are no specific criteria that define the level of amputation in diabetic patients. The objective of this study was to assess the influence of clinical and laboratory parameters in determining the level of amputation and the wound healing time. Methods: One hundred and thirty-nine diabetic patients were retrospectively assessed. They underwent surgical procedures due to infection and/or ischemic necrosis. Type of surgery, antibiotic use, laboratory parameters and length of hospital stay were evaluated in this study. Results: The most common amputation level was transmetatarsal, occurring in 26 patients (28.9%). The wound healing time increased with statistical significance in individuals undergoing debridement, who did not receive preoperative antibiotics and did not undergo vascular intervention. Higher levels of amputation were statistically related to limb ischemia, previous amputation and non-use of preoperative antibiotics. Conclusion: Patients with minor amputations undergo stump revision surgery more often, but the act of always targeting the most distal stump possible decreases energy expenditure while walking, allowing patients to achieve better quality of life. Risk factors for major amputations were ischemia and previous amputations. A protective factor was preoperative antibiotic therapy. Level of Evidence III, Retrospective Study.
