title: Syntax Score I and II for Predicting Carotid Artery Stenosis in Patients with Multivessel Coronary Artery Disease: A Propensity Score Matching Analysis

description: Abstract Objective: To evaluate the predictive accuracy of SYNTAX score (SS) I and II for detecting significant carotid artery stenosis (CAS) in patients with multivessel coronary artery disease undergoing coronary artery bypass grafting (CABG) surgery. Methods: The study population consisted of 416 patients. Clinical, demographic, and radiological records were retrospectively reviewed. Characteristics of patients with CAS (n=66) and patients without CAS (n=350) were compared before and after propensity score matching analysis. Results: Patients with significant CAS were older compared to those without significant CAS [(60 (53-65) vs. 63 (59-67); P=0.01]. However, atherosclerotic risk factors and SS I were similar between groups. SS II CABG and percutaneous coronary intervention (PCI) were significantly higher in patients with CAS [37.4 (30.9-43.5) vs. 33.8 (29.9-38.9); P=0.02]. After propensity score matching analysis (66 vs. 66), age, SS II PCI and CABG were significantly higher in patients with CAS than those without CAS [37.4 (30.9-43.5) vs. 33 (29.3-36.9); P=0.03]. Age, SS II PCI and CABG were associated with CAS in logistic regression analysis [OR=1.086, 95% CI (1.032-1.143), P&lt;0.001; OR=1.054, 95% CI (1.010-1.101), P=0.02; OR=1.078, 95% CI (1.029-1.129), P&lt;0.01]. In ROC curve analysis, SS II PCI &gt;33.1 had 68.2% sensitivity and 54.6% specificity [AUC=0.624, P=0.01, 95% CI (0.536-0.707)] whereas SS II CABG &gt;26.1 had 81.8% sensitivity and 54.6% specificity [AUC=0.670, P&lt;0.01, 95% CI (0.583-0.749)] to predict CAS. Pairwise comparison of ROC curves revealed similar statistical accuracy for prediction of CAS (z statistic: 0.683, P=0.49) Conclusion: SS II is useful to predict asymptomatic CAS in patients with multivessel coronary artery disease.

title: A Reading Using the Lens of the Anthropological Teaching Theory about a Lesson on Numerical Expressions

description: Abstract This research is immersed in a research of greater magnitude, in which the Anthropological Theory of Didactics - TAD and its organizational structure constitute the core of the study. In this text, we present a clipping, with emphasis on the transcription of a descriptive protocol of the filming of a 6th grade class of Elementary School II, which dealt with numerical expressions. We undertake some interpretations through a reading using the theoretical lens of said theory in which aspects related to mathematical and didactic organizations were evidenced. In this perspective, our analysis will be based on the descriptive protocol of the class and demonstrate how the TAD can contribute to design an organizational structure of a mathematical object, as well as to reveal gaps linked to the absence of the raison d’être of this content institutionally present in the curricular matrix of this educational level. The documentary analysis, in a qualitative approach was used in this study that followed a configuration and transit through some records of the class transcription and allowed us to weave interconnections with what the TAD postulates. The scope of the article presents, in a first moment, the exposition of the institutional sustentation of the numerical expressions and sums up to the evolutionary path of the TAD exposing in its genesis the study of the conditions and restrictions undergone by the mathematical objects. We culminate revealing the first structure and some elements that will support the class characterization and the mathematical problem that concomitantly turns into a didactic problem.

title: The Activity Theory in Mathematics Interactive Digital Didatic Material

description: Abstract In this article, we discuss how the formal mathematical language, digital technologies, the internet, virtual learning environments, and the interaction between distance learning participants can influence and transform the production of knowledge in distance learning courses. We consider the research that gave rise to this article as a collective case study, since the data were produced during the development of Linear Algebra disciplines of four distance teacher education courses in Mathematics linked to the Open University of Brazil (UAB). We base our analyzes on the theory of activity and the epistemological view that surrounds the construct humans-with-media. Methodologically, we adopt the qualitative paradigm, having as sources of data production observation in virtual learning environments, interviews, political pedagogical projects and field notes. Data analysis was based on the grounded theory rooted in the activity theory itself. The results indicated that the difficulty in communicating and expressing the formal mathematical language in the virtual learning environment generated tensions and transformations that resulted in the production of interactive digital didactic material.

title: Systematization of evaluation instruments for the two first years of life of typical or risk infants according to the ICF model

description: ABSTRACT The objective of this study was to identify low-cost instruments of evaluation of neuropsychomotor development (NPMD) of children aged zero to two years, that can be used in the context of daycare and/or clinical environment in early intervention programs, and to systematize these instruments as the biopsychosocial model of the International Classification of Functioning, Disability and Health (ICF). NPMD evaluation instruments with translation or adaptation for Brazil were selected. For this purpose, the ICF domains were chosen triangulating the ICF-CY’s own checklist, the early stimulation core set, and the latest version of the ICF for searching the evaluation instruments in literature. Two physical therapists and a third for discordant items performed the systematization of the selected categories of ICF. The scales that met the criteria were: Alberta Infant Motor Scale (AIMS), Denver II Screening Test, PedIatric Quality of Life Inventory (PedSQl ™), Affordance in the Home Environment for Motor Development-Infant Scale (AHEMD-IS) and Mother-child bond. Even with these scales, there was a need for a complementary anamnesis questionnaire for the infant’s caregiver, data from the Child Health Handbook and a socioeconomic questionnaire from the Brazilian Association of Research Companies for Brazil (ABEP). This systematization is available in the appendix and seeks to facilitate the broader view of the physical therapist or education professional with a biopsychosocial comprehension of the infants, in addition to allowing the early identification of risks and subsidizing actions of promotion and intervention in different contexts.

title: Wolfram syndrome - Clinical diagnosis of rare multisystemic condition

description: Abstract Wolfram Syndrome consists of a neurodegenerative pathology of genetic character, also known by the acronym DIDMOAD that translates the main findings of this disease, Diabetes Insipidus, Diabetes Mellitus, Optic Atrophy and Deafness. The article report the case of a patient diagnosed clinically with this syndrome in a general ophthalmology out patient clinic. Considering that patients with this genetic alteration have more than one cranial nerve affected by the disease and clinical history without meningitis or other neurological alterations, one has to think about rare alterations, as is the case with this syndrome. From the diagnosis, the WRUS questionnaire was applied in consultation, which all owed the comparation of the patient with concepts obtained internationally available in the literature.

title: Comparison of Sharp Dissection, Electrocautery, and Ultrasonic Activated Scalpel with Regard to Endothelial Damage, Preparation Time, and Postoperative Bleeding During Radial Artery Harvesting

description: Abstract Objective: To examine the effects of classical technique, electrocautery, and ultrasonic dissection on endothelial integrity, function, and preparation time for harvesting the radial artery (RA) during coronary artery bypass grafting (CABG). Methods: Forty-five patients who underwent isolated CABG and whose RA was suitable for use were studied and divided into three groups: Group 1, classical method (using sharp dissection); Group 2, electrocautery; and Group 3, ultrasonic cautery. Levels of prostacyclin and nitric oxide derivatives were examined biochemically; vascular cell adhesion molecule 1 (VCAM-1) and endothelial nitric oxide synthetase (eNOS) values were assessed using immunohistochemical staining. RA preparation time, RA length/harvesting time ratio, and drainage amounts at the site of RA removal were compared. Results: Differences in RA preparation time (Group 1: 25±6 min, Group 2: 18±3 min, Group 3: 16±3 min, P&lt;0.001) and length/harvesting time ratio (Group 1: 0.76±0.19 cm/min, Group 2: 0.98±0.16 cm/min, Group 3: 1.13±0.09 cm/min, P&lt;0.001) were statistically significant among the groups. Levels of prostacyclin and nitric oxide derivatives were not statistically significant different, VCAM-1 and eNOS expressions were observed to be similar among the groups, and endothelial damage was detected in only one patient per group. Conclusion: Use of ultrasonic cautery during RA preparation considerably reduces the preparation time and postoperative drainage amount. However, the superiority of one method over the others could not be demonstrated when the presence of endothelial damage with both biochemical and histopathological evaluations was considered.

title: Prevalence of Masked and White-Coat Hypertension in Pre-Hypertensive and Stage 1 Hypertensive patients with the use of TeleMRPA

description: Abstract Background: The diagnosis of arterial hypertension based on measurements of blood pressure in the office has low accuracy. Objective: To evaluate the prevalence of masked hypertension (MH) and white-coat hypertension through home blood pressure monitoring (HBPM) in pre-hypertensive and stage 1 hypertensive patients. Method: Retrospective study, of which sample consisted of individuals with BP ≥ 120/80 mmHg and &lt; 160/100 mmHg at the medical office without the use of antihypertensive medication and who underwent exams on the HBPM platform by telemedicine (TeleMRPA) between May 2017 and September 2018. The four-day MRPA protocol was used, with 24 measurements, using automated, validated, calibrated equipment with a memory function. Results: The sample consisted of 1,273 participants, of which 739 (58.1%) were women. The mean age was 52.4 ± 14.9 years, mean body mass index (BMI) 28.4 ± 5.1 kg/m2. The casual BP was higher than the HBPM in 7.6 mmHg for systolic blood pressure (SBP) and 5.2 mmHg for diastolic blood pressure (DBP), both with statistical significance (p &lt; 0.001). There were 558 (43.8%) normotensive individuals; 291 (22.9%) with sustained hypertension; 145 (11.4%) with MH and 279 (21.9%) with white-coat hypertension (WCH), with a diagnostic error by casual BP in the total sample in 424 (33.3%) patients. In stage 1 hypertensive individuals, the prevalence of WCH was 48.9%; in prehypertensive patients, the prevalence of MH was 20.6%. Conclusion: MH and WCH have a high prevalence rate in the adult population; however, in prehypertensive or stage 1 hypertensive patients, the prevalence is higher. Out-of-office BP measurements in these subgroups should be performed whenever possible to prevent misdiagnosis.

title: Long-Term Assessment of Left Ventricular Ejection Fraction and Mitral Regurgitation Following Takeuchi Repair

description: Abstract Objective: This study aimed to evaluate the early operative outcomes and to compare the left ventricle and mitral valve functions after initial Takeuchi repair in patients with anomalous left coronary arising from pulmonary artery (ALCAPA). Methods: Fourteen patients (5 males, 9 females; mean age 4.3 years, ranging from 25 days to 34 years) who were operated for ALCAPA between 2007 and 2018 were included in this study. Data were evaluated retrospectively based on our medical records. Results: Hospital mortality rate was 7.1% (n=1). Thirteen surviving patients were kept in follow-up mean 4.3±3.05 years. When compared to preoperative measurements, both left ventricular ejection fraction (LVEF), (P=0.007) and mitral regurgitation (MR) (P=0.001) significantly improved before discharge. Moreover, LVEF values were improved in the late follow-up, considering early postoperative outcomes, and this alteration was significant (P=0.014). Nevertheless, alteration in the degree of MR among patients did not differ in the long-term follow-up (P=0.180). There was no late-term mortality or need for reoperation among patients. Conclusion: Although some centers prefer to direct implantation in ALCAPA, Takeuchi procedure can be accepted as a reliable method that provides satisfactory long-term results, considering that it aids to improve left ventricle ejection fraction and reduced mitral valve regurgitation.
