Authors: Sorte Paulo Boa 
Published: August 2018

This paper aims at analyzing the perceptions of English teachers about the theoretical bases discussed in a teacher development course named Digital Environments: theory and practice in the classroom. The course, which focuses on promoting digital literacies, is offered by the Federal University of Sergipe (UFS) in partnership with the Undergraduate Center for Distance Education at UFS and the research group E-Lang from UNICAMP. Among the theoretical bases of this study are the authors who discuss the inclusion of digital technologies at schools and English classes as well as the notion of digital literacies (BAWDEN, 2008; BRAGA, 2013; COLL ET AL, 2010; LANKSHEAR & KNOBEL, 2008; LEMKE, 1998; SANTAELLA, 2013). For data analysis, it is taken into accountthe messages posted on the platform where the course is offered, i.e. discussion forums and reflective electronic diary. The results show how the participating teachers understand conceptions such as technology, hyperlinks and digital literacies. In addition, it is observed the relevance of discussing issues related to the official guidelines for teaching foreign languages in Brazil, which leads to the need for the teacher to be constantly involved in professional develpoment.

Authors: Yang Brianna , Chung Chun-Hsi 
Published: August 2018

ABSTRACTObjectives:To evaluate and compare the buccolingual inclinations of maxillary and mandibular first molars in untreated children and adults.Materials and Methods:One hundred and thirty-eight subjects were selected and divided into three groups, as follows: (1) age 6–9 years, N = 46; (2) age 10–19 years, N = 56; and (3) age 25–35 years, N = 36. For each subject, existing cone beam computed tomography images were used, and the long axis for each maxillary and mandibular first molar was determined. The converge angles formed by the long axis of left and right maxillary first molars and by the long axis of left and right mandibular first molars were measured.Results:The maxillary molars exhibited buccal inclination, with the converge angle of 21.1° ± 9.5° in group 1, 17.3° ± 8.6° in group 2, and 9.3° ± 7.3° in group 3. Statistically significant differences were found between groups 1 and 3 and groups 2 and 3, but not between groups 1 and 2. The mandibular molars exhibited lingual inclination, with the converge angle of 34.9° ± 11° for group 1, 26.6° ± 9.2° for group 2, and 26.1° ± 7.7° for group 3. Statistically significant differences were found between groups 1 and 2 and groups 1 and 3, but not between groups 2 and 3.Conclusions:Maxillary first molars exhibited buccal inclination. Adults displayed less inclination than did children. Mandibular first molars exhibited lingual inclination. Adults displayed less inclination than did children. Some degree of curve of Wilson should be maintained at the end of orthodontic treatment to fulfill physiologic needs and stability.

Published: August 2018

ABSTRACT

Objectives:
To evaluate the influence of text messages on cooperation of Class II patients with the use of intermaxillary elastics.

Materials and Methods:
The sample consisted of 42 orthodontic patients (20 males and 22 females) aged between 14 and 34 years. They were randomly divided into one of the following two groups: a control group with 21 patients who did not receive messages and an experimental group with 21 patients who received motivational and reminder text messages. Messages were sent twice a week for a period of 3 months. The patients were instructed to wear the elastics all day, removing them only during meals and replacing them daily. All patients were instructed regarding the importance of cooperation. Measurements were performed with a digital caliper on plaster models at the beginning of elastics wear (T1) and 3 months later (T2). For intragroup and intergroup comparisons between T1 and T2, paired and unpaired t-tests, respectively, were used with a significance level of 5%.

Results:
Statistically significant differences were observed in the intra- and intergroup comparisons between T1 and T2. Both groups showed a decrease in the sagittal distance between upper and lower arches from T1 to T2, demonstrating the effective use of elastics. However, the experimental group showed a Class II correction that was 3.7 times greater than the control group (P = .001).

Conclusions:
Text messages had a positive influence on the cooperation of patients regarding the use of intermaxillary elastics in the orthodontic treatment of Class II malocclusion.
A 15-year follow up of an orthodontic treatment including a lower incisor extraction and keeping the maxillary canine–premolar transposition
Authors: Hwang Soonshin , Kim Insil , Jang Woowon , Choi Yoon Jeong , Chung Chooryung J. , Kim Kyung-Ho 
Published: August 2018

ABSTRACT
Lower incisor extraction is an effective option for treating lower anterior crowding in patients with a good facial profile, Class I molar occlusion, and narrow upper incisors. This report describes the successful treatment of an adolescent patient with lower anterior crowding and a transposed maxillary canine and premolar treated by extracting a lower incisor and keeping the transposed positions of the teeth. With the use of retainers, treatment results were stable up to the 2-year postretention visit. However, upon a 15-year postretention appointment, the fixed retainer had been removed and the removable retainer was no longer in use, which resulted in relapse of lower anterior alignment. Moreover, the transposed canine had extruded during this period, causing occlusal interference and gingival recession, as well as loss of tooth vitality, which indicates the importance of maintaining orthodontic retainers for long-term stable occlusion.

ABSTRACT
This report illustrates successful nonsurgical orthodontic treatment of a hypodivergent adult patient with bilateral posterior scissors bite (Brodie bite) and excessive overjet. A 26-year-old woman primarily reported maxillary incisor protrusion. She was diagnosed with Class ll division 1 malocclusion with skeletal Class I, short face, low mandibular plane angle and bilateral posterior scissors bite. A lingual arch with anterior bite block and posterior miniscrews with preadjusted edgewise appliances were used to improve the bilateral scissors bite. After achieving molar occlusion, the maxillary first premolars were extracted, and six miniscrews were used to improve the anterior-posterior and vertical discrepancies. After active treatment for 56 months, the convex facial profile with excessively protruded lips was improved and good interdigitation with ideal incisor relationship was achieved. Additionally, the irregular movements of the incisal path and the bilateral condyles during lateral excursion were improved. At 13 months of retention, a satisfactory facial profile, occlusion, and jaw movements were maintained. The treatment results suggest that miniscrews and fixed bite blocks were effective and efficient to facilitate correction of the bilateral scissors bite, excessive overjet, and vertical relationship correction in this nonsurgical orthodontic treatment.

OBJECTIVE
Roux-en-Y gastric bypass (RYGB) induces type 2 diabetes remission (DR) in 60% of patients at 1 year, yet long-term relapse occurs in half of these patients. Scoring methods to predict DR outcomes 1 year after surgery that include only baseline parameters cannot accurately predict 5-year DR (5y-DR). We aimed to develop a new score to better predict 5y-DR.

RESEARCH DESIGN AND METHODS
We retrospectively included 175 RYGB patients with type 2 diabetes with 5-year follow-up. Using machine learning algorithms, we developed a scoring method, 5-year Advanced-Diabetes Remission (5y-Ad-DiaRem), predicting longer-term DR postsurgery by integrating medical history, bioclinical data, and antidiabetic treatments. The scoring method was based on odds ratios and variables significantly different between groups. This score was further validated in three independent RYGB cohorts from three European countries.

RESULTS
Compared with 5y-DR patients, patients who had relapsed after 5 years exhibited more severe type 2 diabetes at baseline, lost significantly less weight during the 1st year after RYGB, and regained more weight afterward. The 5y-Ad-DiaRem includes baseline (diabetes duration, number of antidiabetic treatments, and HbA1c) and 1-year follow-up parameters (glycemia, number of antidiabetic treatments, remission status, 1st-year weight loss). The 5y-Ad-DiaRem was accurate (area under the receiver operating characteristic curve [AUROC], 90%; accuracy, 85%) at predicting 5y-DR, performed better than the Diabetes Remission score (DiaRem) and the Advanced-DiaRem (AUROC, 81% and 84%; accuracy, 79% and 78%, respectively), and correctly reclassified 13 of 39 patients misclassified with the DiaRem. The 5y-Ad-DiaRem robustness was confirmed in the independent cohorts.

CONCLUSIONS
The 5y-Ad-DiaRem accurately predicts 5y-DR and appears relevant to identify patients at risk for relapse. Using this score could help personalize patient care after the 1st year post-RYGB to maximize weight loss, limit weight regains, and prevent relapse.
Safety and Efficacy of Exenatide Once Weekly Plus Dapagliflozin Once Daily Versus Exenatide or Dapagliflozin Alone in Patients With Type 2 Diabetes Inadequately Controlled With Metformin Monotherapy: 52-Week Results of the DURATION-8 Randomized Controlled Trial

OBJECTIVE
Among patients with type 2 diabetes uncontrolled with metformin, exenatide once weekly (QW) plus dapagliflozin combination produced greater reductions in glycemia, weight, and systolic blood pressure (SBP) at 28 weeks than exenatide QW or dapagliflozin alone (DURATION-8). Here, we investigated the safety and maintenance of efficacy at 52 weeks, after a 24-week extension.

RESEARCH DESIGN AND METHODS
This phase 3, multicenter, double-blind study randomized adults with type 2 diabetes (with glycated hemoglobin [HbA1c] 8.0–12.0% [64–108 mmol/mol] and on metformin ≥1,500 mg/day) to exenatide QW (2-mg subcutaneous injection) plus once-daily dapagliflozin (10-mg oral tablet), exenatide QW plus oral placebo, or dapagliflozin plus injected placebo. Extension-period P values were nominal.

RESULTS
Of 1,375 patients screened, 695 were randomized (mean baseline HbA1c 9.3% [78 mmol/mol]); 81.2% completed the study, and 75.3% completed treatment. At 52 weeks, HbA1c reductions were greater with exenatide QW plus dapagliflozin (least squares mean change −1.75% [−19.1 mmol/mol]) versus exenatide QW (−1.38% [−15.1 mmol/mol]; P = 0.006) or dapagliflozin (−1.23% [−13.4 mmol/mol]; P &lt; 0.001); mean HbA1c values were 6.9% (52 mmol/mol), 7.2% (55 mmol/mol), and 7.4% (57 mmol/mol), respectively. Weight and SBP reductions were greater with exenatide QW plus dapagliflozin (−3.31 kg and −4.5 mmHg) versus exenatide QW (−1.51 kg and −0.7 mmHg; both P &lt; 0.001) but similar to those with dapagliflozin (−2.28 kg and −2.7 mmHg; P = 0.057 and P = 0.100, respectively). The exenatide QW plus dapagliflozin regimen was well tolerated with no unexpected safety findings; more patients treated with exenatide QW experienced gastrointestinal and injection site–related adverse events. No major hypoglycemia occurred.

CONCLUSIONS
Among patients with type 2 diabetes uncontrolled with metformin, exenatide QW plus dapagliflozin provided sustained improvements in glycemia, weight, and SBP over 52 weeks, with no unexpected safety findings.

Introduction. Our first experience in embolization of prostatic arteries at patients with benign prostatic hyperplasia had comprised patients with the symptoms of chronic urinary retention.Material and methods. The average age of patients (n=3) was 61.0±4 years. Among medical indications to embolization there were dysuria significantly degrading the patients’ life quality and their unwillingness to proceed to transurethral resection. Before the embolization of the prostatic artery, it is necessary to identify the place of its departure and its anastomosis by computed tomography. Successful operation was effectuated without microcatheter guides in 3 cases and with the application of microcatheter guides in 3 cases. For the purposes of embolization there were used spherical embolus HydroPearl sized 400 nm. No complications were reported neither in the operational nor in the post-operational periods.Results. All patients admitted a decrease in dysuria as well as the improvement in life quality already in 7–15 days after the endovascular invasion. Control ultrasound dopplerography was performed 3 months after intervention. Two patients with embolization showed decrease of prostate volume by 26%, and one patient — by 35%.Conclusions. Embolization of the prostatic arteries is a promising low-traumatic and safe method for treating patients with benign prostatic hyperplasia. It is necessary to further study its long-term results, to develop an optimized methodology — fast, simple and cheap, but not at the expense of efficiency and safety.

Published: August 2018

Introduction.Pulmonary embolism (PE), being the most severe embolic complication, is characterised by low predictability, high mortality and incapacitation rates as well as a correspondingly high economic cost of therapy and aftercare. In this connection, the main purpose of our work is to find a warning for PE development in non-cardiosurgical patients that have undergone intensive therapy under conditions of general surgical ICU, among the indicators of the haemostasis system.Materials and methods. Based at the anaesthesiology and emergency surgical department № 1 of the Kuvatov Republic Clinical Hospital (Russia), the researchers carried out an analysis of the haemostasis system in 430 patients hospitalised between 2010 and 2014. The functional activity of platelets was studied using a Biola 230LA laser platelet aggregation analyser (Russia). The determination of circulating aggregates was conducted using the Wu — Hoak method. Thromboelastography was carried out using a TEG 5000 Thromboelastograph (USA). A Stago STA Compact automated selective haemostasis analyser (France) was used to register indicators that characterise the state of endothelium, the haemostatic coagulation element and thrombosis and fibrinolysis markers.Results. Univariate analysis demonstrated a connection between nosocomial episodes of thrombosis and the following factors: emergency surgery (OR 9.1, p<0.01), peripheral vessel disease (OR 13.5, p=0.01), collapse development in pre-operation period (OR 30, p<0.01), high content of D-dimers (OR 30, p<0.01) and low content of AT III (OR 13.5, p=0.01). The results of multifactor analysis show that the significant diagnostic criteria are high D-dimer content and low AT III venous blood activity.Conclusion. A determination of high risks will enable the incidence of pulmonary embolism to be to minimised as well as provide a timely assessment of the efficiency of preventive measures carried out.

Introduction. Atherosclerotic lesions of the branches of the aortic arch in 60% of cases is the cause of the development of ischemic stroke. As a radical means of preventing neurological disorders, carotid endarterectomy is used, since there is currently no effective drug treatment.Material and methods. This article presents a comparative characteristic of anesthesiological support and types of surgical intervention in 710 patients with atherosclerotic lesions of brachiocephalic arteries in the period from January 2010 to December 2017 in Department of Vascular Surgery at the Clinic of the Bashkir State Medical University. To perform this comparative characteristic, the patients were divided into 2 groups, depending on the time interval. Group 1 — patients operated from 2010 to 2013 (291 patients). Group 2 — patients operated from 2014 to 2017 (491 patients). In Group 1, operations were predominantly performed under regional anesthesia and classical carotid endarterectomy predominated over an eversion. In Group 2, operations were performed under general anesthesia, and here the overthe-top carotid endarterectomy predominated over the classical one. Patients were comparable in age, sex and risk of anesthesia and surgical intervention according to the ASA classification. The overall incidence of ischemic postoperative complications was 4.22%.Results. According to our data, the application of the eversion method of carotid endarterectomy under general anesthesia reduces the relative risk of neurological complications by 1.648 times (as in the 2nd group the technique of eversion carotid endarterectomy under general anesthesia was used). The use of general anesthesia with carotid endarterectomy allows to provide adequate gas exchange, manageability by hemodynamic parameters, absence of emotional reactions from the patient.Conclusion. Thus, at the present moment, our experience in treating patients with atherosclerotic lesions of the brachiocephalic arteries is approaching the optimal one, allowing us to achieve good results of carotid endarterectomy.

Introduction. Presently there is no unified tactics to treat patients with aberrantly localized coronary arteries of “muscular bridge” type. There are controversial data regarding the benefit of coronary artery stenting due to often stent breakage or perforation of tunneled vessel. There are no major randomized studies regarding this issue. In this regard the goal of this research was to assess strength characteristics of stents in the model of muscular growth that we restored.Materials and methods. The originally developed model enabled to determine the strength limit of coronary stents under conditions that are maximum close to the physiological ones. The stents were placed into a polytetrafluoroethylene tube, the bridge-imitating oscillation frequency was configured to 250 beats per minute. The results of the experiment were recorded on USB-camera each 30 minutes in order to register mechanical defects of the stent.Results and discussion. The stent consisting of cells that are joined with V-shaped connections, showed first signs of strut deformity on the 10th day. Complete breakage happened on the 17th day after implantation. After 2 months observation the stent preserved mechanical firmness without V-shaped connections.Conclusion. Thus, it is not quite correct to support the hypothesis on infeasibility of stent implantation into the coronary artery with a muscular bridge. Taking into consideration the findings it is possible to suppose that the structure, design, form and content of stents predetermine the possibility to implant it into coronary artery with muscular bridge, but require individual approach to every particular patient.
