title: Total entropy variation for an object in contact with heat reservoirs: the path to reversibility

description: Abstract The second law of thermodynamics is one of the least understood fundamental physical laws, even among science and engineering students and professionals, possibly due to its subtleness and several seemingly different statements. Here we investigate the entropy variation of an isolated system composed of an object of heat capacity C(T) and one or more heat reservoirs, as the absolute temperature of the object varies due to heat exchange with subsequent reservoirs. We obtain a general expression for the total entropy variation, ΔS(0), in terms of C(T) and the number of reservoirs N. We numerically show that ΔS(0) decreases as N increases, and considering that as N → ∞ the temperature difference between subsequent reservoirs becomes infinitesimal, we analytically show that     lim  N → ∞ Δ  S  ( 0 ) = 0, in accordance with the second law of thermodynamics for a reversible quasi-static process. We conclude by proposing an undergraduate exam problem based on the demonstration that the total entropy variation vanishes in the quasi-static limit.

title: Partial replacement of corn by soybean hulls in high-grain diets for feedlot sheep

description: Abstract: The objective of this work was to evaluate the partial replacement of corn grains by soybean hulls, in high-grain diets, and its effect on the feeding behavior and ruminal fermentation parameters of feedlot sheep. Eight rumen-cannulated crossbred sheep were assigned to four treatment groups composed of a control, to fed a diet of 50% corn silage and 50% concentrate, and to three groups fed high-grain diets, as follows: 85% corn (Diet85), 75% corn plus 10% soybean hulls (Diet75), and 65% corn plus 20% soybean hulls (Diet65). High-grain diets reduced rumination time and provided a higher degradation of feed dry matter, a higher-propionic acid concentration, a lower-acetic acid concentration, a lower methane and carbon dioxide gas production, and a lower ruminal pH value. Diet65, with 20% soybean hulls, promoted an increase in the acetic acid proportion, with a reduction in the CO2:CH4 ratio. At the end of in vitro incubation, the pH value was higher for the control diet, and it was lower for Diet85. The inclusion of soybean hulls does not change methane production and dry matter degradation, and it can be used to substitute up to 20% of corn grain in high-grain diets.

title: Iatrogenic Ureteral Obstruction During Transvaginal Oocyte Retrieval

description: ABSTRACT Transvaginal oocyte retrieval is a crucial step in assisted reproductive technology. Various complications may arise during this procedure. Ureteral injury is a rare, but a serious complication in gynecological practice. During oocyte retrieval, ureteral injuries, detachment and obstruction can be seen, though rare. In this study, we will present ureteral obstruction that develops secondary to small hematoma, which mimics ovarian cyst torsion or ruptured ovarian cyst.

title: Moderate or severe LUTS is associated with increased recurrence of non - muscle - invasive urothelial carcinoma of the bladder

description: ABSTRACT  Purpose: Non - muscle - invasive bladder cancer (NMIBC) can recur despite transurethral resection (TURBT) and adjuvant intravesical therapy. Tobacco products excreted in the urine are hypothesized to cause tumor - promoting effects on urothelial cells through direct contact. We determined if moderate or severe lower urinary tract symptoms (LUTS) (defined as International Prostate Symptom Score [IPSS] ≥ 8) was associated with increased tumor recurrence.  Materials and Methods: We retrospectively identified 70 consecutive men initially diagnosed with NMIBC at our institution from 2010 – 2016. Means were compared with independent T - test and proportions with chi - square analysis. Multivariate logistic regression was performed to determine independent predictors of recurrence.  Results: The majority of patients had Ta disease (58.6%) followed by T1 (28.6%) and Tis (12.9%). Forty - one (58.6%) patients had moderate or severe LUTS upon presentation within 30 days of initial TURBT with mean IPSS of 13.2 vs. 5.2 in the control group (p &lt; 0.01). Biopsy - proven tumor recurrence occurred in 24 (34.3%) patients at mean follow-up of 31.7 months. Mean time to recurrence was 14.6 months. Moderate or severe LUTS was an independent predictor of tumor recurrence (odds ratio [OR]: 19.1, 95% confidence interval [CI]: 2.86 – 127; p = 0.002). Voiding or storage symptoms based on the IPSS did not independently correlate with tumor recurrence (p = 0.08 and p = 0.31, respectively) although total mean IPSS score did (OR: 1.26, 95% CI: 1.07 – 1.47, p = 0.005).  Conclusions: The presence of moderate or severe LUTS may be an important prognostic factor in NMIBC. Patients with significant urinary symptoms could be monitored more aggressively due to higher recurrence risk.

title: Molecular analysis of translocations associated with Ewing sarcoma: case report

description: ABSTRACT We report the case of a 25-year-old female patient having a large lesion in the right breast. The core biopsy revealed a high-grade fusocellular neoplasm. Immunostains show no evidence of a specific line of differentiation. The patient underwent radical surgery and adjuvant treatment. Due to the immunohistochemical profile and the rosette arrangement in fusocellular injury, a molecular evaluation of translocations associated to the Ewing sarcoma (ES) was made. However, translocations commonly associated with this disease [t(11;22)(q24;q12)] were not observed. The present report can contribute to the diagnostic investigation of similar cases and to the pre-test orientation of the molecular evaluation.

title: Translation and Transcultural Adaptation of the Instrument of Evaluation of Medical Education in Musculoskeletal Disorders

description: ABSTRACT Disorders of the musculoskeletal system represent between 10-25% of the reasons for consultations in primary care, however, only a small percentage of the undergraduate curriculum is dedicated to the study of this subject. Thus, it is necessary to develop objective instruments to assess this deficiency in medical schools. The Freedman and Bernstein questionnaire is an internationally validated tool for assessing basic medical knowledge of musculoskeletal disorders and, consequently, evaluate medical training. The objective of this study was to develop a version of the scale in the Portuguese language, validated and adapted transculturally for the Brazilian population. Transcultural translation and adaptation of the questionnaire was conducted following the steps of initial translation, back-translation, composition of a pre-final version and its test, making the necessary changes after this last phase and development of the final model of the instrument. The pre-final version was applied to the target audience of the research - 15 students in the last semester of Medicine. Each individual answered the questions from the survey and was then interviewed to analyze their understanding of what was expected in each item of the questionnaire. Both the interpretation of the question and the response were explored. There were difficulties in understanding two questions, making it necessary to substitute some terms to facilitate assimilation. After the changes, there were no impediments to the participants’ understanding of the final instrument. Content validation was assessed by a panel of experts who considered the terms and scope of the translated questionnaire appropriate. This assessment was made after the final test and no change was recommended. Thus, the questionnaire is translated into the Portuguese language, presenting semantic, idiomatic, conceptual and cultural equivalence with the original. Its use is recommended for the evaluation of the teaching of musculoskeletal disorders in the country’s medical schools, allowing a comparison of the Brazilian orthopedic curriculum with international standards.

title: Antibiotic prophylaxis prior to urodynamic study in patients with traumatic spinal cord injury. Is there an indication?

description: ABSTRACT  Study design: Retrospective cohort of patients with traumatic spinal cord injury (SCI) that have been hospitalized for physical-functional rehabilitation purposes.  Objectives: To compare the incidence of urinary tract infection (UTI) after urodynamic study (UDS) in three hospitals that adopted different protocols with regard to the preparation of patients.  Setting: Sarah Network of Rehabilitation Hospitals, Brazil.  Materials and Methods: Between 2014 and 2015, 661 patients from three units of the same hospital network, one of which does not use antimicrobial prophylaxis independently of urine culture results, were evaluated after having undergone UDS. The results were compared in both univariate and multivariate analyses (logistic regression).  Results: The global rate of UTI after UDS was that of 3.18% (IC 95% 2.1-4.8), with no differences between the units. In the univariate analysis the only variable that was associated with UTI after UDS was that of T6 injuries or above (P = 0.029). The logistic regression has confirmed this result, with an adjusted odds ratio of 3.06 (IC 95% 1.01 to 9.26; P = 0.0476). The use of antimicrobial prophylaxis did not alter that risk.  Conclusions: This study has demonstrated that the use of antimicrobials does not prevent UTI after UDS. Patients with T6 traumatic SCI or above have got three times more chance of developing UTI after UDS if compared to those with a T7 injury or below, independently of the use of antimicrobials. Even in these patients the use of antimicrobials would not be justified.

title: Crossover transseptal vasovasostomy: alternative for very selected cases of iatrogenic injury to vas deferens

description: ABSTRACT Inguinal herniorraphy is a possible cause of iatrogenic seminal tract obstruction. Diagnosing and correcting these vasal injuries can be challenging. Successful re-anastomosis is technically challenging, with relatively low success rates. An uncommon alternative for selected cases is the crossover transseptal vasovasostomy. We herein report a case of a 36-year-old male patient with vas deferens injury after herniorraphy and a contralateral hypotrophic testis. He was successfully treated through microsurgical crossover transseptal vasovasostomy, with spontaneous pregnancy achieved, and the technique is presented in details.

title: MONITORING THE COMPOSITION IN ESTERS OF THE BIODIESEL FROM THE MACAÚBA (Acrocomia aculeata (Jacq.) Lodd. ex Mart.) KERNEL OIL PUT IN DIRECT CONTACT WITH CARBON STEEL AND GALVANIZED CARBON STEEL

description: The oil from the macaúba (Acrocomia aculeata) fruit, a native palm in Brazil, has a real potential for the industrial production of biodiesel. This report describes an experimental work devoted to monitor the chemical behavior of the fatty acid methyl esters from oil of the macaúba fruit kernel and the leaching of metal elements into the biodiesel put in contact with the ASTM A283 grade C and API X65 carbon steels, used to build fuel storage tanks and biodiesel pipelines. The mean values of esters contents points that the analytical precision from atomic absorption measurements was not enough to support a statistically reliable interpretation of the chemical leaching of metals into the biodiesel; a more accurate set of data must be obtained with more sensitive chemical analytical techniques. From the Mössbauer data, the surface of the non - galvanized steels in contact with this biodiesel for up to 105 days tend to be somehow protected against most oxidative reactions even in direct contact with air, although few amount magnetite (Fe3O4) was detected.

title: Comparison of the ankle-brachial index with parameters of stiffness and peripheral arterial resistance assessed by photoplethysmography in elderly patients

description: Abstract  Background The ankle-brachial index (ABI) uses the ratio between systolic blood pressures at the ankle and the arm to diagnose peripheral arterial disease (PAD) noninvasively. Photoplethysmography (PPG) measures and records changes to the blood volume in the human body using optical techniques.  Objectives The objective of this study was to compare ABI with arterial stiffness and peripheral resistance parameters assessed using PPG in elderly patients and to propose a model for prediction of ABI.  Methods A cross-sectional, quantitative study was conducted. The sample comprised elderly patients seen at a medical specialties clinic at the Universidade do Sul de Santa Catarina (UNISUL), Brazil. Age, sex, body mass index (BMI), comorbidities, smoking, and physical activity were recorded. The variables obtained using PPG and ABI were compared using bivariate and multivariate linear regression, with an α error of 0.05.  Results A total of 93 elderly patients were assessed, 63.4% of whom were women. In 98.9% of cases, ABI was within normal limits. Comparison of ABI with variables acquired by PPG revealed significant associations with age. However, no significant associations were observed between ABI and PPG. The multivariate model indicated that only age, sex, and smoking were associated with ABI.  Conclusions In conclusion, ABI and PPG exhibited associations with arterial aging, considering its correlation with age. However, ABI was only related to age, sex, and smoking. More studies are needed to evaluate the potential uses of PPG for screening for vascular diseases in ambulatory settings.

title: Determination of Short Chain Fatty Acids in Mice Feces by Capillary Electrophoresis

description: Short-chain fatty acids (SCFA) are compounds produced during fermentation of gut microbiota. Acetic, propionic and butyric acids are the most important SCFA produced from non-digestible foods. We developed and validated a rapid and low-cost capillary electrophoretic (CE) method for determination of acetic, propionic and butyric acids in mice feces (100 mg of sample). Electrophoretic separation was performed for SCFA determination in feces samples during 10 min. The method showed good linearity for all analytes (determination coefficient, r2 &gt; 0.98); recovery from 74.1 to 109.8%, while the intra- and interday precision essays were suitable (relative standard deviation (RSD) &lt; 10%); and limits of detection and quantification of 0.13-0.43 mM for acetic acid, 0.09-0.29 mM for propionic acid and 0.03-0.09 mM for butyric acid. Real samples of mice dextran sulfate sodium-induced colitis feces treated with jabuticaba (Plinia cauliflora) aqueous extract were performed successfully.
