title: Arterial bullet embolism after thoracic gunshot wound

description: Abstract Bullet embolization of the arterial or venous systems is a rare complication of penetrating gunshot injuries. A 29-year-old man presented at the emergency department with a gunshot wound to the left arm, which had transfixed the arm and entered the thorax, with no exit wound. Initial radiographies showed a projectile in the upper left thigh. Contrast-enhanced tomography showed a pseudo-aneurysm of the descending thoracic aorta and the bullet inside the proximal left superficial femoral artery. Physical examination found diminished left pedal pulses, and the patient complained of left toe numbness. Endovascular thoracic aortic pseudoaneurysm repair was performed, sealing the descending aortic orifice with an endograft, and thromboembolectomy/bullet retrieval was carried out via a left femoral incision, both successfully. Considering that diagnosis of missile emboli depends on a high degree of suspicion, physicians who manage gunshot wound patients must be acutely aware of the possibility of intravascular bullet embolism.

title: Sustainability of student debt in demand-led macrodynamics

description: Abstract This paper analyzes the sustainability of student debt in a theoretical model in which economic activity is determined by aggregate effective demand. While most of the literature on this topic only considers the wage differentials among workers with distinct educational levels, we propose a formal methodology that considers the impact of this indebtedness on certain macroeconomic variables that affect the possibility of serving the outstanding debt, such as the rate of employment. We compare two forms of debt repayment, the first being similar to the “ Income-Driven Repayment Plans”, which have become common in the U.S. as of late, while, in the second, households’ marginal propensity to consume adapts, to some extent, to the debt service. Our results indicate that factors such as the distribution of income and marginal propensities to consume of different functional classes affect the macroeconomic conditions related to the sustainability of student debt.

title: Ichthyofauna of the Una river in the Paraíba do Sul Paulista River Valley, Southeastern of Brazil

description: Abstract: This study focus on an inventory of the ichthyofauna of the Una river, a tributary of the Paraíba do Sul river, located in the region of Paraíba do Sul River Valley, in the State of São Paulo. Sampling was carried out in three sampling areas along the channel of the Una river between April 2016 and March 2017. For the collection of fish specimens, was used angling, fyke nets, cast nets, dragnets and hand nets. A total of 1.534 specimens were collected, which corresponds to five different orders, 14 families, 26 genera and thirty species. The study revealed that the most significant number of reported species are from the orders Siluriformes and Characiformes. The Characidae family was the most representative concerning the wealth of species and Astyanax aff. bimaculatus (two spot Astyanax | lambari-do-rabo-amarelo) was the species with the highest number of individuals captured. The freshwater ichthyofauna of the Una river is composed of eight species considered allochthonous and one exotic. Of the thirty species listed in this study, five are new records for the Paraíba do Sul river basin.

title: A city almanac as research object of the history of written culture: Almanack da Parnahyba (1924-1982)

description: ABSTRACT This study concerns the Almanack da Parnahyba, a periodic book classified as a city almanac. Understood as a historical document, the immersion in its pages made it possible to construct some aspects as they are connected to the history of written culture in Piauí, more specifically in the city of Parnaíba. From the analysis of the almanac, it was possible, through the characteristics of its materiality, to understand its editing process, its circulation and relation with its readers. It was observed that, in the period investigated, the almanac could be found in different Brazilian states; moreover, its presence was identified in some countries other than Brazil. During its publication, the almanac functioned, directly or indirectly, as a voice of civility ideals, anchored in a process of modernization discourse.

title: Vascular Forum: collective intelligence in the resolution of vascular clinical cases

description: Abstract Background Collective intelligence is extremely important in collective groups that discuss clinical medical cases, assisting professionals in their decision-making processes, and consequently, helping their patients. Objectives To evaluate the rate of resolution and characteristics of the clinical discussions carried out in a private instant messaging group and its clinical applicability. Methods Retrospective analysis of clinical discussions and events on the Vascular Forum, an open group for specialists accessed with mobile devices. Results From July 2015 to July 2017, 1013 subjects were discussed among 680 members. Twenty-six (2.57%) of these subjects were curiosities, 101 (9.97%) related to diagnostic doubts, 492 (48.57%) to treatment doubts, and 205 (20.24%) to general doubts, while 189 (17.5%) were case reports. The mean number of interactions per event was 16.599 (±1.366). The mean time from posting of a new subject to the first reply was 42.14 (±7.55) min. The subject discussed was miscellaneous in 358 cases, venous in 336 cases, lymphatic in 15 cases, and arterial in 304 cases and the total number of replies was 15985. Conclusions Interaction between experts using instant messaging technology proved capable of raising subjects for discussion and eliciting management approaches quickly. The rate of resolution, defined as the time taken for the first correct answer to be posted, was also high. The Vascular Forum proved to be a tool of great clinical value for its participants, confirming the importance of collective intelligence in medicine.

title: The role of vascular echography in the management of complications associated with central venous access for hemodialysis in cancer patients: two case reports and literature review

description: Abstract Central venous catheter implantation for hemodialysis is commonly performed in large centers and its complications are sometimes associated with insufficient training of those who perform it, but may also be related to the patient’s clinical condition. The present study reports two cases of complications related to use of a short-stay catheter for hemodialysis. In the first case, the cannula was inadvertently inserted into the left subclavian artery, causing arterial thrombosis, which was conservatively managed and good collateral perfusion was documented with vascular echography. The second case illustrates an incidental finding of Central Venous Septic Thrombosis in a patient who had used a catheter for a week, which was treated with antibiotic therapy, anticoagulation, and ultrasound control. In both cases, surgical intervention would have been high risk because of the patients' poor prognosis. Vascular ultrasonography enabled monitoring of these clinical situations and use of less aggressive treatments.

title: Is Preoperative Clopidogrel Resistance a Predictor of Bleeding and Risks in Patients Undergoing Emergency CABG Surgery?

description: Abstract Objective: The aims of this study were to determine whether the detection of preoperative clopidogrel resistance in patients undergoing cardiac surgery while using clopidogrel could play a guiding role in the prediction of postoperative excessive bleeding, transfusion requirements, and risks and to provide clinically significant data. Methods: Two hundred and twenty-two patients [median age: 59.4 (38-83) years; 38 females] undergoing emergency and elective coronary artery bypass graft (CABG) surgeries in our clinic were evaluated prospectively. Patients with multiple systemic diseases, other than diabetes mellitus (DM) and hypertension (HT), were excluded. Patients receiving clopidogrel were also evaluated for clopidogrel resistance and grouped according to the results of this test. Assessments of platelet functions were performed by multiplate impedance aggregometry method and adenosine diphosphate test. Results: The use of postoperative fresh blood replacement and platelet transfusion was higher in patients receiving clopidogrel than in those not receiving it (P=0.001, P=0.018). DM, HT, myocardial infarction, and the number of presentation to the emergency room were significantly higher in patients receiving clopidogrel than in those not receiving it (P&lt;0.05). No significant difference was determined between patients with and without clopidogrel resistance regarding the amount of bleeding during and after surgery, erythrocyte suspension and fresh-frozen plasma transfusion rates, preoperative troponin values, ejection fraction values, and length of hospital stays (P&gt;0.05). Conclusion: We think that resistance studies in patients receiving clopidogrel before cardiac surgery are not efficient to predict bleeding and bleeding-related complications in patients undergoing emergency and elective CABG surgeries.

title: Does the use of glycerin gel improve the color stability of composite resins?

description: Abstract Introduction The resin composite superficial layer not polymerized due to the presence of oxygen leads to clinical problems as color alteration by the absorption of pigments. Objective Evaluate the effect of different techniques to control the formation of the composite resin dispersion layer on the optical properties of a commercial composite. Material and method Resin composite Estelite Sigma specimens were made. The specimens were light-cured with the LED Bluephase G2 device (1200 mW/cm2 - 40 s). The groups were determined according to three different techniques: 1) no treatment (control); 2) light-curing through a glycerin gel layer on the surface; 3) polishing with abrasive discs after light-curing. The color stability (ΔE) and the translucency parameter were determined by the spectroscopy method (Easyshade Compact Vita) as a function of the CIELab parameter. The analyzes were performed immediately after photoactivation and repeated after 7 days of storage in water or 7 days in coffee. The results were submitted to ANOVA and Tukey test (α = 0.05). Result No difference was found for ΔE in groups aged in water. When stored in coffee, the control group had the highest value of ΔE while the polished group generated the lowest color change. The glycerin gel groups promoted intermediated results. The translucency parameter was not affected by the treatments tested. Conclusion: The glycerin-based gel layer minimizes the color change in those regions that the finishing and polishing instruments are difficult to access.

title: Social Networks in the scientific production on public health administration in Brazil

description: Abstract The Brazilian administrative reform was included in the 1988 Constitution, and it has promoted decentralized policies, including the municipalization of health and popular participation. The objective of this article is to understand how the implementation of these democratic changes were studied in the international literature. The scientific production on Brazilian public health administration was analyzed by studying social networks. The search was conducted in the Web of Science database, using administration terms, delimited by “Brazil” and “health,” and using BibExcel and Ucinet software. The network of publications in administration was cohesive, containing practices of deliberative democracy and social participation. By including the term “health,” more variations were found, particularly on the Brazilian Health Reform and on the decentralization of the National Health System, with a more critical and reflexive focus, albeit with a clear gap on social accountability.
