title: Computed tomography angiography study of variations of the celiac trunk and hepatic artery in 100 patients

description: Abstract Objective: To describe the main anatomical variations of the celiac trunk and the hepatic artery at their origins. Materials and Methods: This was a prospective analysis of 100 consecutive computed tomography angiography studies of the abdomen performed during a one-year period. The findings were stratified according to classification systems devised by Sureka et al. and Michels. Results: The celiac trunk was "normal" (i.e., the hepatogastrosplenic trunk and superior mesenteric artery originating separately from the abdominal aorta) in 43 patients. In our sample, we identified four types of variations of the celiac trunk. Regarding the hepatic artery, a normal anatomical pattern (i.e., the proper hepatic artery being a continuation of the common hepatic artery and bifurcating into the right and left hepatic arteries) was seen in 82 patients. We observed six types of variations of the hepatic artery. Conclusion: We found rates of variations of the hepatic artery that are different from those reported in the literature. Our findings underscore the need for proper knowledge and awareness of these anatomical variations, which can facilitate their recognition and inform decisions regarding the planning of surgical procedures, in order to avoid iatrogenic intraoperative injuries, which could lead to complications.

title: Companies, violation of human rights and the Brazilian civil-military dictatorship: a National Truth Commission perspective

description: Abstract This article means to identify and highlight, using documented sources provided by the National Truth Commission, the involvement of Brazilian companies in acts and processes involving human rights violations during the Brazilian civil-military dictatorship years. In order to achieve this objective, our focus of interest has been concentrated on analyzing the second volume of the final report, more specifically, text n. 2 (“Human rights violations relating to workers”) and text n. 8 (“Civilians who collaborated with the dictatorship”). According to this document, corporate human rights violations occurred on four fronts: (1) through the use of repression and control by means of persecution, imprisonment and torture; (2) through the portrayal of workers as subversives and enemies of the Brazilian nation; (3) through the creation and publication of black lists, and; (4) through political, ideological and financial aid given to the repressive structures of the dictatorial regime.

title: Inclusion and intellectual disability: special and common schools under the point of view of students themselves

description: ABSTRACT Considering that under the banner of inclusion school transfers between special and common schools have been taking place throughout national territory, it is necessary to investigate how the public students of these schools perceive this process, since the literature warns about the absence of student participation on the decisions about their schooling process. This work aimed to investigate the thoughts of students with intellectual disabilities (ID) on special and regular schools, taking their school transfers as a scenario, be this transfer from the special to the common school or vice versa. It is a descriptive research with multiple case design that involved the study of five cases of ID students who were transferred. The instruments used for data collection were the Drawing-and-Story procedure with the students and complementary interviews with family members. The analysis of the data allowed us to identify that the students assigned to the special school the role of reception and care, and to the common school a place of learning and knowledge, with awareness that these are two distinct forms of schooling, each with its pros and cons. The analysis of the results shows that the study reached its objectives and brought practical, political and scientific implications related to the schooling of the students with ID, especially when giving voice to the target of the school transfer.

title: Mindfulness-Based Cognitive Therapy in Major depressive disorder - systematic review and metanalysis

description: Abstract Introduction: MBCT practices increases the ability of concentration and attention, as well is particularly effective for people with current and treatment-resistant depression. Objective: To analyze the effects of the application of MBCT in symptoms of MDD. Methods: systematic review and meta-analysis. To find suitable studies, we searched PubMed/MEDLINE's database using the keywords mindfulness and major depressive disorder. Studies in English published between 2003 and 2015 were selected. The studies were evaluated according to their methodological quality by PEDro scale (score greater than 3), studies that showed empirical evidence, had an experimental study design (randomized and non-randomized), and whose full text was available. For the meta-analysis, we used a random-effects model with standardized mean differences and 95% confidence intervals. Results: Fourteen es were included, of which three were non-randomized, with only one group with intervention of MBCT, and 11 were randomized studies, divided into two-group samples and three-group samples. The non-randomized studies showed a PEDro score of 5, while the two-group and three-group randomized studies showed PEDro scores of 5-10 and 6-9, respectively. In the meta-analysis, the four randomized studies selected revealed a moderate effect of MBCT on the outcome of depression symptoms, with a mean difference of -0.52 (95% CI: -1.050 to -0.002; p = 0.04). Conclusion: The MBCT presented as a promising alternative for the treatment of this disorder.

title: Upper and lower limb functionality and body mass index in physically active older adults

description: Abstract Introduction: Aging leads to sarcopenia and functional capacity decline, compromising upper (UL) and lower limb (LL) performance of activities. Body mass index (BMI) is an important parameter for the assessment of health conditions in older adults, especially with regard to obesity, since it leads to functional limitations in terms of mobility and task performance. Objective: To investigate the potential association between UL and LL functionality and BMI in physically active older adults; and to characterize this population with regard to BMI and UL and LL functionality. Methods: The data were collected between August 2013 and April 2014. The sample comprised 371 physically active older adults. This study used secondary data from the program “PET Saúde IPA/SMS”. The program interviewed older adults living in areas comprised by the Third Family Health Unit of a neighborhood in Porto Alegre/RS. This paper used questions from the “Instrumento de Avaliação Multidimensional Rápida da Pessoa Idosa” (Instrument for Rapid Multidimensional Assessment of Elderly People, in English) that had to do with UL and LL functionality, weight, height and BMI. Results and Conclusion: There was no association between UL and LL functionality and BMI in physically active older adults. More than half of the sample was overweight. Most participants had functional UL and LL. While occupation, self-perception of health as “good” and “very good”, and physical activity were found to be associated with LL functionality; regular physical exercise was found to be associated with UL and LL functionality.

title: Magnetic resonance imaging: dynamic contrast enhancement and diffusion-weighted imaging to identify malignant cervical lymph nodes

description: Abstract Objective: To examine the potential of two magnetic resonance imaging (MRI) techniques-dynamic contrast enhancement (DCE) and diffusion-weighted imaging (DWI)-for the detection of malignant cervical lymph nodes. Materials and Methods: Using DCE and DWI, we evaluated 33 cervical lymph nodes. For the DCE technique, the maximum relative enhancement, relative enhancement, time to peak enhancement, wash-in rate, wash-out rate, brevity of enhancement, and area under the curve were calculated from a semi-quantitative analysis. For the DWI technique, apparent diffusion coefficients (ADCs) were acquired in the region of interest of each lymph node. Cystic or necrotic parts were excluded. All patients underwent neck dissection or node biopsy. Imaging results were correlated with the histopathological findings. None of the patients underwent neoadjuvant treatment before neck dissection. Results: Relative enhancement, maximum relative enhancement, and the wash-in rate were significantly higher in malignant lymph nodes than in benign lymph nodes (p &lt; 0.009; p &lt; 0.05; and p &lt; 0.03, respectively). The time to peak enhancement was significantly shorter in the malignant lymph nodes (p &lt; 0.02). In the multivariate analysis, the variables identified as being the most capable of distinguishing between benign and malignant lymph nodes were time to peak enhancement (sensitivity, 73.7%; specificity, 69.2%) and relative enhancement (sensitivity, 89.2%; specificity, 69.2%). Conclusion: Although DCE was able to differentiate between benign and malignant lymph nodes, there is still no consensus regarding the use of a semi-quantitative analysis, which is difficult to apply in a clinical setting. Low ADCs can predict metastatic disease, although inflammatory processes might lead to false-positive results.

title: Magnetic resonance arthrography of the shoulder: a painful procedure?

description: Abstract Objective: To compare the pain expected to that effectively caused by magnetic resonance arthrography of the shoulder and, secondarily, to describe a simplified approach to the technique for articular access. Materials and Methods: We prospectively evaluated 40 participants who used a visual analog scale and a simplified categorical scale to indicate the level of pain expected and that experienced after the procedure, comparing the two with the Wilcoxon matched-pairs test. We also determined gender-related differences in pain conditions using the Mann-Whitney U test. In addition, we described a modified technique involving radiographic localization and the use of standard puncture needles for articular access. Results: Analysis of the visual analog scales showed that the pain experienced was less than had been expected, with median scores of 1.75 and 3.75, respectively (p &lt; 0.001). The level of pain expected was higher among women than among men, with median scores of 8.0 and 3.0, respectively (p = 0.014), as was the level of pain experienced, with median scores of 3.0 and 1.5, respectively (p = 0.139). The overall categorical evaluation corroborated that difference (p = 0.03). Articular access with the modified technique was successful in all patients. Conclusion: Magnetic resonance arthrography of the shoulder is less painful than patients expect. In addition, digital radiographic guidance combined with the use of standard puncture needles appears to improve the efficiency of the method.

title: Ultrasound-guided biopsy of breast calcifications using a new image processing technique: initial experience

description: Abstract The aim of this paper is to describe the use of a new ultrasound imaging processing technique to guide biopsies of suspicious breast calcifications. We used this technique in 13 patients with suspicious breast calcifications that could not be submitted to stereotactic biopsy. Suspicious calcifications were identified by ultrasound, and the biopsy was successfully performed in all cases. Although mammography continues to be the method of choice for the detection and characterization of microcalcifications, this new technique can be an alternative means of guiding biopsy procedures in selected patients who are not candidates for stereotactic biopsy.
