title: Magnetic resonance imaging of sellar and juxtasellar abnormalities: atypical findings of common diseases and typical findings of rare diseases

description: Abstract The sellar/juxtasellar region comprises the bone component of the sella turcica, pituitary gland, cavernous sinus, and suprasellar cistern. Abnormalities in this region can be attributed to underproduction or overproduction of hormones or to the neurological signs and symptoms resulting from the compression of adjacent structures. Magnetic resonance imaging (MRI) is currently the imaging method of choice, having supplanted computed tomography. The aim of this study was to demonstrate the common and uncommon imaging aspects of sellar and juxtasellar changes, which could facilitate the differential diagnosis. We retrospectively evaluated the MRI scans of 70 patients with sellar/juxtasellar abnormalities from didactic files, and report those with more unusual changes, where MRI played an important role in diagnosis. All cases were confirmed histologically or clinical laboratory.

title: Sports injuries in soccer according to tactical position: a retrospective survey

description: Abstract Introduction: In soccer, the players’ positions have been associated with specific functional overload, which may cause sports injuries. Objective: To investigate the occurrence and characterize sport injuries according to soccer player position. Methods: 232 male soccer players (129 professionals and 103 amateurs) from different sport teams in Mato Grosso do Sul, Brazil, were distributed in groups according to their soccer player position. Besides anthropometric characteristics, sports injuries were registered by using a referred morbidity survey. The occurrence of injuries was analyzed by means of the Goodman Test. Logistic regression models were used to investigate the relationship between different risk factors and the occurrence/-recurrence of sports injuries. Results: Forwards showed higher occurrence rates of sport injuries than other soccer position groups. Joint injuries in lower limbs constituted the most frequent registered cases. Muscle injuries in the back region were the most registered sports injuries among midfielders, while muscle damages in lower limbs were the primary injuries registered for other line positions. In the etiologic context, contact was the main cause of sports injuries in all groups. Most athletes (195) reported recurrence of sports injuries. Conclusion: The occurrence of sports injuries was higher among forwards. Traumatic joint and muscle injuries were the most prevalent registers in all line positions.

title: Which dose of bevacizumab is more effective for the treatment of aggressive posterior retinopathy of prematurity: lower or higher dose?

description: ABSTRACT Purpose: To compare 0.5 mg and 0.625 mg of bevacizumab for treating aggressive posterior retinopathy of prematurity (AP-ROP). Methods: The medical records of patients with AP-ROP who were administered intravitreal bevacizumab (IVB) as a primary treatment at a university clinic were evaluated retrospectively. Five eyes of three patients (Group 1) who received 0.625 mg/0.025 ml IVB and 10 eyes of another five patients (Group 2) who received 0.5 mg/0.02 ml IVB were evaluated. Laser photocoagulation was used as additional treatment after relapses. Anatomic results and complications were evaluated in both groups. Results: We evaluated 15 eyes of eight patients (four girls and four boys) with a flat demarcation line at posterior zone 2 and plus disease or stage-3 disease in this study. The mean gestational age of the three babies in Group 1 was 26 ± 1 weeks and the mean birth weight was 835.33 ± 48.01 g. The corresponding values were 25.2 ± 1.6 weeks and 724 ± 139.03 g, respectively, for the five babies in Group 2. Retinal vascularization was completed at a mean postmenstrual duration of 53.6 ± 1.5 weeks without additional treatment in the five eyes in Group 1. Laser photocoagulation for relapse was administered to five of the 10 eyes in Group 2. Retinal vascularization was completed at a mean postmenstrual duration of 47.6 ± 1.5 weeks in the remaining five eyes. None of the patients developed complications such as cataract, glaucoma, retinal tear, retinal or vitreous hemorrhage, or retinal detachment. Conclusion: Although lower IVB doses in the treatment of AP-ROP are expected to be safer in terms of local and systemic side effects in premature infants, these patients may require additional treatment with IVB or laser photocoagulation.

title: The socio-spatial dysfunction in mass housing cities of Algeria: technical wayfinding analysis by method “movement traces” and morphology analysis (space syntax) by software “depthmap”

description: Abstract This document develops a model of analysis and investigation of the impact of the socio-spatial dysfunction of the pedestrian movement, as well on urban reproduction, especially the transformations of the facades and also the appropriation of outdoor spaces in mass housing cities of Algeria. The technical analysis and spatial syntax of the visibility (Visibility Graph Analysis – VGA) and the accessibility (All Line Analysis – ALA) was performed by the software “DepthMap©(UCL, Londres)” and the wayfinding dysfunction analysis by the method of “movement traces”. This is a case study as the city 1000 housing of Biskra and city 500 housing of M’sila. In order to verify this hypothesis, we developed a hybrid analysis model, the diagram interference of the two techniques. The interference results show that the majority of pedestrians prefer straight roads and shorter axes with a strong syntax property of visibility and accessibility (integration, connectivity and intelligibility) in directions of the peripheral equipment (adjacent) and to the center of the two cities. These routes have a direct impact on the transformations of the facades and also the appropriation of outdoor spaces. The model developed promises future research on the quantification, modeling and simulation of the process, in particular by cellular automata.

title: Weight reduction for a better visual outcome in idiopathic intracranial hypertension

description: ABSTRACT Purpose: To evaluate the correlation between weight reduction and visual outcome in overweight patients with idiopathic intracranial hypertension. Methods: Thirty-nine newly diagnosed, overweight (body mass index &gt;25 kg/m2) patients with idiopathic intracranial hypertension were studied retrospectively. All patients underwent medical treatment with acetazolamide, and a weight reduction program was also offered. Patients were grouped according to their compliance with this weight reduction program into the diet-success (Group 1) and diet-failure groups (Group 2). Body mass index, papilledema, visual acuity, and perimetric mean deviation were compared at the end of the 6-month study period. Results: Groups 1 and 2 did not differ regarding the baseline mean body mass index (32.63 ± 5.61, 32.35 ± 5.06 kg/m2), visual acuity (0.080 ± 0.13, 0.130 ± 0.24 logMAR), perimetric mean deviation (-9.978 ± 0.68, -12.86 ± 8.91), or papilledema grade (2.94 ± 0.22, 2.90 ± 0.30), respectively (p&gt;0.05). During the 6 months' follow-up, Group 1 patients, who complied with both medical and diet therapy, improved significantly in all parameters, including body mass index (p&lt;0.001), visual acuity (p=0.001), perimetric mean deviation (p=0.016), and papilledema grade (p&lt;0.001). Conversely, Group 2 patients, who only underwent medical therapy, improved only in papilledema grade (p&lt;0.001). However, coincident development of optic disc pallor was observed in three patients. Further, they also had significant loss in visual acuity (p=0.047) during the study period. Conclusion: Weight reduction combined with medical treatment is associated with significantly better improvement in visual acuity, visual field, and papilledema in idiopathic intracranial hypertension patients. Compliance with an efficient diet program should be encouraged in overweight patients with idiopathic intracranial hypertension.

title: Social Representations of the Gypsy Woman among Non-Gypsy Brazilian and Italian Population: Psychological and Social Anchoring

description: ABSTRACT Based on the non-consensual approach of the Theory of Social Representations, the present study aimed to investigate the processes of social and psychological anchoring regarding the social representations of the gypsy woman, dimension which allows analyzing the modulation of the social objects from the interindividual positioning and the experiences shared by subjects of the representation according to their sociocultural context of insertion. The study included 643 non-gypsy, Brazilian and Italian individuals with mean age of 22.81 years (SD=5.73). Once lexical correspondence analysis was conducted, the process of psychological anchoring indicated the formation of eight clusters, which characterize different representations, according to the following dimensions: magical-religious, maternity and care of the family-group, social exclusion, and female figures. Through the analysis of the social anchoring process, we verified that variables such as contact, gender, and nationality act in the modulation of these different representations over the object, producing ambiguities that have historically led to processes of discrimination against gypsy groups.

title: Myocardial T1 mapping and determination of partition coefficients at 3 tesla: comparison between gadobenate dimeglumine and gadofosveset trisodium

description: Abstract Objective: To compare an albumin-bound gadolinium chelate (gadofosveset trisodium) and an extracellular contrast agent (gadobenate dimeglumine), in terms of their effects on myocardial longitudinal (T1) relaxation time and partition coefficient. Materials and Methods: Study subjects underwent two imaging sessions for T1 mapping at 3 tesla with a modified look-locker inversion recovery (MOLLI) pulse sequence to obtain one pre-contrast T1 map and two post-contrast T1 maps (mean 15 and 21 min, respectively). The partition coefficient was calculated as ΔR1myocardium /ΔR1blood , where R1 is 1/T1. Results: A total of 252 myocardial and blood pool T1 values were obtained in 21 healthy subjects. After gadolinium administration, the myocardial T1 was longer for gadofosveset than for gadobenate, the mean difference between the two contrast agents being −7.6 ± 60 ms (p = 0.41). The inverse was true for the blood pool T1, which was longer for gadobenate than for gadofosveset, the mean difference being 56.5 ± 67 ms (p &lt; 0.001). The partition coefficient (λ) was higher for gadobenate than gadofosveset (0.41 vs. 0.33), indicating slower blood pool washout for gadofosveset than for gadobenate. Conclusion: Myocardial T1 times did not differ significantly between gadobenate and gadofosveset. At typical clinical doses of the contrast agents, partition coefficients were significantly lower for the intravascular contrast agent than for the extravascular agent.

title: Impact of Team Competencies on Performance

description: ABSTRACT Job competences have been traditionally understood as individual properties. However, due to the increasing implementation of teams in organizations, is defended also that competences can be treated as a collective characteristic. The main goal of this study was demonstrate that competencies are collective properties and they act as predictors of team performance. The empirical study was undertaken with information collected from 51 Brazilian airports which tasks are organized on teams (106; 3 until 33 members). Team members offered information about competences, and leaders offered information about performance of teams. The results demonstrated that collective competencies explain around 20% of the performance. Based on those results, team competences are defended as collective characteristic that predict results of teams.
