title: Functional capacity and mental state of patients undergoing cardiac surgery

description: Abstract Introduction: Cardiovascular diseases are a serious public health problem in Brazil. Myocardial revascularization surgery (MRS) as well as cardiac valve replacement and repair are procedures indicated to treat them. Thus, extracorporeal circulation (ECC) is still widely used in these surgeries, in which patients with long ECC times may have greater neurological deficits. Neurological damage resulting from MRS can have devastating consequences such as loss of independence and worsening of quality of life. Objective: To assess the effect of cardiac surgery on a patient’s mental state and functional capacity in both the pre- and postoperative periods. Methods: We conducted a cross-sectional study with convenience sampling of subjects undergoing MRS and valve replacement. Participants were administered the Mini-Mental State Exam (MMSE) and the Duke Activity Status Index (DASI) in the pre- and postoperative periods, as well as before their hospital discharge. Results: This study assessed nine patients (eight males) aged 62.4 ± 6.3 years with a BMI of 29.5 ± 2.3 kg/m2. There was a significant decrease in DASI scores and VO2 from preoperative to postoperative status (p = 0.003 and p = 0.003, respectively). Conclusion: This study revealed a loss of cognitive and exercise capacity after cardiac surgery. A larger sample however is needed to consolidate these findings.

title: Laparoscopic-assisted prepubic urethrostomy: experimental model in rabbit

description: ABSTRACT: The purpose of this study was to develop a laparoscopic-assisted prepubic urethorstomy (PPU) technique using rabbits as an experimental model. Six male New Zealand rabbits (Oryctolagus cuniculus) over six months old and weighing between 3 and 4kg (3.5kg ± 0.4) were used in this study. The animals underwent laparoscopic dissection of the pelvic urethra, which was then exposed for the laparoscopic-assisted urethrostomy procedure. The proposed model for training of laparoscopic-assisted PPU in rabbits was considered effective and feasible. It proved to be a simple technique even for surgeons under basic endosurgery skills training, with possibilities of employing the technique for the treatment of cats with loss of function of the distal urethra.

title: Increasing students’ skills in operations management classes: Cumbuca Method as teaching-learning strategy

description: Abstract This paper analyses the use of the Cumbuca Method as a teaching strategy to develop reading skills in engineering students. Despite their importance, reading skills are little stimulated in engineering undergraduate courses. Teamwork, communication, organization and exposure of ideas, time management are also important skills to new employees. The Cumbuca Method was created to disseminate quality concepts among company employees, by discussing text related to a given topic of interest. This analysis is based on a qualitative approach involving a sample of 200 engineering undergraduates from Operations Management discipline at a public University in the State of Sao Paulo, Brazil. The results showed that the use of this teaching strategy inducted improvements to regular reading and debate among students.

title: Metabolic evaluation in overweight and obese cats and association with blood pressure

description: ABSTRACT: Obesity has been increasing in cats andis associated with metabolic and cardiovascular diseases. The association of these alterations can trigger the onset of metabolic syndrome (MS). Therefore, this study aimed to analyze the serum levels of glucose, fructosamine, cholesterol, triglycerides, high-density lipoprotein, low-density lipoprotein, very low-density lipoprotein (VLDL), andalanine aminotransferase of cats and to identify the possibility of MS,as well as to evaluate changes in arterial pressure. Thirty-seven cats were classified by ECC and morphometric measurements, namely, 15 obese, 12 overweight, and 10 controls. Nocat manifested MS. Only VLDL had a statistically significant difference (P&lt;0.05) between groups. Therefore, obesity may not be associated with arterial hypertension, and more studies are needed to evaluate the metabolic alterations in overweight and obese cats.

title: Arteriovenous malformation of the external ear: a clinical assessment with a scoping review of the literature

description: Abstract Introduction: Auricular Arteriovenous Malformation of the external ear is a rarely encountered disease; in particular, arteriovenous malformation arising from the auricle, with spontaneous bleeding, has seldom been reported. Objective: In the current study, we report an unusual case of late-onset auricular arteriovenous malformation originating from the posterior auricular artery that was confirmed by computed tomographic angiography. The case was successfully managed by pre-surgical intravascular embolization followed by total lesion excision. Prompted by this case, we also present a scoping review of the literature. Methods: A case of a 60 year-old man with right auricular arteriovenous malformation treated in our tertiary care center, and 52 patients with auricular arteriovenous malformation described in 10 case reports and a retrospective review are presented. Auricular arteriovenous malformation can manifest as swelling of the ear, pulsatile tinnitus, pain, and/or bleeding. On physical examination, a pulsatile swelling and/or a tender mass is evident. When arteriovenous malformation is suspected, the lesions should be visualized using imaging modalities that optimally detect vascular lesions, and managed via embolization, mass excision, or auricular resection. Effectiveness of the various diagnostic methods used and the treatment outcomes were analyzed. Results: Various imaging modalities including Doppler sonography, computed tomographic angiography, magnetic resonance angiography, and/or transfemoral cerebral angiography were used to diagnose 38 cases reported in the literature. In another 15 cases, no imaging was performed; treatment was determined solely by physical examination and auscultation. Of the total of 53 cases, 12 were not treated (their symptoms were merely observed) whereas 20 underwent therapeutic embolization. In total, 32 patients, including 1 patient who was not treated and 10 with persistent or aggravated arteriovenous malformation after previous embolization, underwent mass excision or auricular resection depending on the extent of the lesion. No major postoperative complication was recorded. The postoperative follow-up duration varied from 1 month to 19 years, and only one case of unresectable, residual cervicofacial arteriovenous malformation was recorded. Conclusion: Auricular arteriovenous malformation is a rarely encountered disease, but should be suspected if a patient presents with a swollen ear and pulsatile tinnitus. Appropriate imaging is essential for diagnosis and evaluation of the extent of disease. As embolization affords only relatively poor control, total surgical removal of the vascular mass is recommended.

title: Description and evaluation of experimental models for uterine transplantation in pigs

description: ABSTRACT Objective: To evaluate the technique of uterine transplantation and the use of drugs used in the process of immunosuppression. Methods: We included 12 sows, and immunosuppression was performed with minimal doses of cyclosporine, and cross-match was done to exclude the possibility of blood incompatibility. Hysterectomy was performed in the donor under general anesthesia, with the removal of the aorta and inferior vena cava in monobloc, and anastomosis of these vessels was made in the recipient. Results: Six experiments were performed, and on the immediate postoperative period, five animals had good reperfusion. However, on the seventh postoperative day, histological analysis showed rejection in five animals. Conclusion: The experimental model of uterine transplantation is feasible, but monitoring doses of immunosuppressants is pivotal to prevent rejection episodes.

title: Characteristics of role models who influenced medical residents to choose surgery as a specialty: exploratory study

description: ABSTRACT CONTEXT AND OBJECTIVE: Choosing a medical specialty and making decisions concerning a career are difficult processes for medical students and newly graduated physicians.This exploratory study aimed to investigate the influence of role models on the choice of surgery as a career, and to determine the most influential model characteristics. DESIGN AND SETTING: Qualitative analysis on responses to a self-administered questionnaire, in different teaching-learning settings. METHODS: Residents from all years of various surgical subspecialties in a university hospital were included in a survey about the factors that determined their choice of surgery. The questions included items on whether a role model had influenced them in choosing surgery, and the personal or professional characteristics of the models that had been most influential. The responses were subjected to qualitative content analysis. RESULTS: Sixty-four out of 96 medical residents participated. Fifty-three residents (82.8%) acknowledged the influence of role models. Sixteen model characteristics were indicated as important, with 136 mentions. Characteristics classified as technical skills (55%), such as"medical knowledge"and "manual dexterity" predominated over humanistic characteristics (35%), such as "patient-physician relationships" and "ethical behavior". However, this difference was not statistically significant (Fisher test, P = 0.11).There were no age differences regarding the proportions mentioning "technical" and "non-technical" attributes, but female residents mentioned significantly more technical skills than their male colleagues did. CONCLUSIONS: The influence of role models seems to be an important factor determining the choice of surgery as a career. The influential characteristics of the models include not only technical but also humanistic qualities.

title: Obesity, sarcopenia, sarcopenic obesity and reduced mobility in Brazilian older people aged 80 years and over

description: ABSTRACT Objective: To analyze which abnormalities in body composition (obesity, sarcopenia or sarcopenic obesity) are related to reduced mobility in older people aged 80 years and older. Methods: The sample included 116 subjects aged 80 years and older. The body composition was measured using dual-energy X-ray absorptiometry (DXA) and mobility was assessed by motor tests. The χ2 test was used to analyze the proportion of older people with sarcopenia, obesity and sarcopenic obesity based on sex as well as to indicate an association between obesity, sarcopenia, sarcopenic obesity and mobility. Binary logistic regression, adjusted for the variables (sex and osteoarticular diseases), was used to express the magnitude of these associations. One-way analysis of variance was used to compare the mobility of four groups (Normal, Obesity, Sarcopenia and Sarcopenic Obesity). Results: The Sarcopenia Group had lower performance in the lower limbs strength test and in sum of two tests compared with Obesity and Normal Groups. Older people with sarcopenia had higher chance of reduced mobility (OR: 3.44; 95%CI: 1.12-10.52). Conclusion: Older people aged 80 years and older with sarcopenia have more chance for reduction in mobility.
