title: Podding of Paralomis granulosa (Lithodidae) juveniles inhabiting kelp forests of the Cape Horn Archipelago (Chile)

description: Abstract Subtidal observations along the Cape Horn Archipelago, Chile (CHA) in February 2017 revealed an unusually large aggregation (or pod) of juvenile false king crabs, Paralomis granulosa (Hombron and Jacquinot, 1846), in association with kelp forests (Macrocystis pyrifera and Lessonia spp.). This is the first study to report a dense aggregation of juveniles of this crab, which was observed at Wollaston Island (WI) (~ 10 m). Paralomis granulosa was present on half the transects at WI (N=10), with a density of 3.1 ± 9.9 ind. m-2. Photographs from the podding event showed densities of P. granulosa ranging from 63 to 367 ind. plant-1 (190 ± 133 ind. plant-1). Juveniles (32.8 ± 7.3 mm carapace length) were recorded on kelp fronds, holdfasts, kelp stipes, and adjacent rocky bottom of this protected coast. This podding behavior resembles that of other juvenile king crabs in terms of homogeneity in size structure and may be a predator avoidance mechanism. These observations highlight three aspects of this kelp-animal relationship: (i) identification of a previously unknown ecosystem service provided by sub-Antarctic kelp forests to the associated benthic fauna; (ii) the ecological value of kelp as a bioengineering species; and (iii) pods being an important attribute for population assessments. Due to the importance of the CHA in the life cycle for this and other species, we suggest the archipelago be incorporated within the recently established Diego Ramírez Island-Drake Passage Marine Park.

title: Nomophobia among medical students and its association with depression, anxiety, stress and academic performance

description: Abstract: Introduction: As the world becomes increasingly interconnected, the adoption of technology remains one of the defining factors of human progress. Nomophobia (NO MObile PHOne PhoBIA) represents a mental condition caused by the fear of being detached from mobile phone connectivity. Such condition is directly associated with depression, anxiety, and stress. Moreover, nomophobia can lead to structural brain damage. Objective: The present study aims to assess the effect of nomophobia on medical students at a private institution and its association with depression, anxiety, stress and academic performance. Method: This is a cross-sectional observational study carried out in medical students at Centro Universitário Christus. Nomophobia was measured using the Nomophobia Questionnaire (NMP-Q). The NMP-Q has 20 questions, which are asked on a 7-point Likert scale. This scale has been validated for the Brazilian Portuguese language. Depression, anxiety and stress were measured by the DASS-21, a simplified version of the DASS instrument. The DASS-21 questionnaire was also validated for the Brazilian Portuguese language. Academic performance was measured through API, the product of a complex mathematical operation that results in the student’s average grade in the semester and functions as a reference index for pedagogical follow-up in the assessed institution. In addition, the device use habits were assessed. Descriptive results were presented, and bivariate analyses of association and correlation were performed. This study was approved by the research ethics committee. Result: A sample of 292 students was assessed. Virtually all students (99.7%) had some degree of nomophobia, and 64.5% had a moderate or severe level of nomophobia. More than 50% of the students had higher than mild degrees of stress, and 19.5% and 11.2% of the students had severe or very severe levels of anxiety and depression, respectively. When analyzing the correlation of NMP-Q with DASS-21 scores, it was observed that increases in NMP-Q lead to increases in the overall DASS score (p &lt; 0.001), and that worse results in DASS-21 are associated with worse API. Conclusion: Our study suggests that nomophobia is likely to increase anxiety, stress and depression and, as a result, leads to a decrease in academic performance.

title: Evolution of sex-ratio: Brief review with mathematical study of some simple novel models

description: Abstract Besides reviewing the unusual case of sex-ratio in the lemming and presenting alternative analyses of general models in which the shift in the usual sex-ratio 1:1 is determined by autosomal or sex-linked mutant alleles, three novel models are presented, in which the shift on the progeny sex-ratio depends on the number of copies of a mutant allele present in the parental pair. The analysis of these models with additive effects shows that: 1) autosomal mutations that alter the usual sex-ratio are eliminated from the population; 2) mutations occurring on the X chromosome lead to an evolutionary stable 1:1 sex-ratio only if the mutation favors the production of males; when the mutant allele favors the production of females, however, females will prevail in the population, with a frequency dependent impact on δ (the deviation from the usual 0.5 proportion) ; for most of the range of possible values of δ the stable but extraordinary sex-ratio will vary from 1 male : 1 female to 1 male : 3 females or 1 male : 2 females approximately depending whether the mutant allele is randomly inactivated or not.

title: Coronary Artery Fistula: Association between Pathway Patterns, Clinical Features and Congenital Heart Disease

description: Abstract Background Coronary artery fistula (CAF) is a direct connection of one or more coronary arteries to cardiac chambers or a large vessel; it may be associated with congenital heart disease. Objective To establish CAF pathway patterns from echocardiographic data and to correlate them with clinical aspects and congenital heart disease. Methods A total of 7.183 medical records of children under the age of five years with cardiac disease submitted to color Doppler echocardiography and Spearman’s Correlation test were used to associate signs and symptoms and cardiopathy to CAF with a significance level of 5%. Results Twenty six children (0.0036%) presented CAF: from the right coronary artery (RCA) to the right ventricle (RV) 26.92%, from the left coronary artery (LCA) to the RV 23.08%, from the anterior interventricular branch (AIVB) to RV 23.08%, RCA to right atrium (RA) 11.54%, LCA for pulmonary trunk (PT) 7.69% or AIVB for PT 7.69%. In 57.69% of the patients, there was a positively correlated symptomatology to CAF with p=0.445 related to dyspnea or cyanosis (53.84%); in 96.15%, congenital heart disease associated with CAF, mainly interventricular communication (IVC) or interatrial communication (IAC) in 34.62% positively correlated to CAF with p=0.295. CAF pathway was represented in three dimensions by software modeling, texturing and animation Cinema 4D R19. Conclusion CAF is an uncommon anatomical entity that presents a clinical picture compatible with dyspnea and cyanosis, and this is associated with congenital heart disease, mainly with IVC or IAC. According to echocardiographic analyzes, fistulas in RCA, LCA, or AIVB represent about one-third of the patients, with a priority pathway for right heart chambers.

title: Bilateral Interference of Wind Loads Induced on Duplicate Building Models of Various Shapes

description: Abstract The current investigation focuses on the results of an experimental investigation of Square-plan-shape and Remodel-triangle-shape building model’s varied interference conditions between duplicate building models of 1:300 scale (at 100% blockage) on wind-induced pressure and base moments at fixed 10% of the height of the instrumented model. Under current working conditions, the study concludes that -1 &gt; Interference Factor &gt; 1 as experienced by the Remodel-triangle-shape model results in reduced performance of the instrumented model as opposed to the Square-plan-shape model. Front-to-Front interference condition of Remodel-triangle-shape model has the best overall performance in along-wind and crosswind directions, whereas Front-to-Back interference condition of Remodel-triangle-shape model has the best torsional performance. Back-to-Back interference of a Remodel-triangle-shape model should be avoided because the orientation of duplicate models attracts the most overturning moments in both the along-wind and crosswind directions of all interference conditions investigated in this study.

title: Learning approaches and their correlation with the teaching environment and individual characteristics in medical school

description: Abstract: Introduction: The quality of learning of medical students has been a recurring subject of research in recent decades, but there are scarce national studies on it. The learning environment should encourage deep learning, as it is intimately related to meaningful learning. Active learning methods are linked to better quality of learning, since they provide a favorable environment for deep learning. Objective: The aim of this study was to evaluate the quality of learning of students at a medical school that adopts active learning methods for all course years and correlate it to students’ views on educational environment and sociodemographic data. Method: This is a cross-sectional descriptive study with 1st to 6th-year medical students from the Federal University of São Carlos. The R-SPQ-2f, DREEM and sociodemographic questionnaires were applied. Descriptive analysis was performed, and frequencies were compared using chi-square test or Fisher’s exact test. Differences between means were evaluated with either Student’s t-test or Mann-Whitney’s test, when comparing only two groups, and with one-way analysis of variance (ANOVA) or Kruskal-Wallis’ test, when comparing more than two groups. Associations between quantitative variables were verified with either Pearson’s or Spearman’s correlation coefficient. Statistical analysis was performed with IBM SPSS Statistics version 25.0. For significance, p-value&lt;0.05 was adopted. Result: 226 students were interviewed. The average deep learning score was 33.52 points, and, for superficial learning, 17.42 points. As for how the environment was perceived, the average score was 129.77. The objective variables that showed influence in learning were sex, course start age, previous contact with active learning methods, language study, previous undergraduate training, or post-graduate degree, receiving financial help from family and current course year. Conclusion: Active learning methods may stimulate the adoption of deep learning strategies. The evaluation of factors that influence study approaches is complex, involving subjective individual parameters.

title: Clusters of Cardiometabolic Risk Factors and Their Association with Atherosclerosis and Chronic Inflammation among Adults and Elderly in Florianópolis, Southern Brazil

description: Abstract Background The significant increase in cardiovascular diseases in developing countries alerts about their impact on underprivileged populations. Objective To identify the relationship of clusters of metabolic syndrome (MS) components with atherosclerosis and chronic inflammation among adults and elderly. Methods Cross-sectional analysis using data from two population-based cohort studies in Florianópolis, Southern Brazil (EpiFloripa Adult Cohort Study, n = 862, 39.9±11.5 years; EpiFloripa Aging Cohort Study, n = 1197, 69.7±7.1 years). Blood pressure (BP), waist circumference (WC), and lipid and glucose levels were analyzed as individual factors or as clusters (either as the number of components present in an individual or as combinations of components). Outcomes included carotid intima-media thickness (IMT), atherosclerotic plaques, and C-reactive protein (CRP) levels. Multiple linear and logistic regression analyses adjusted for confounding factors were used. The statistical significance adopted was 5%. Results Individuals with high BP, elevated WC, dyslipidemia and hyperglycemia (6.1% of the sample) showed higher IMT and CRP than those negatives for all MetS components. Elevated WC was a common determinant of systemic inflammation, while the coexistence of high BP and elevated WC (clusters of two or three factors) was associated with higher IMT (β between +3.2 and +6.1 x 10-2 mm; p value &lt; 0.05) and CRP (EXPβ between 2.18 and 2.77; p value &lt; 0.05). Conclusion The coexistence of high BP and elevated WC was associated with increased IMT and CRP levels, but central obesity affected systemic inflammation either alone or in combination with other risk factors.
