title: Relationship between learning styles and simulation in surgery

description: Abstract: Introduction: It was found that the good performance in conventional techniques was not transferable to minimally-invasive alternatives, and then simulators were created for improved learning. Objective: To assess whether robotic virtual reality simulation conditions ability for laparoscopy in medical students, associating the VARK tool and Mind Styles to determine whether there is a correlation between learning styles and the ability to develop these skills. Methods: Randomization of 3 groups of medical students was performed, where one of the groups performed a simulation of a surgical knot exercise in the laparoscopy box and another, the same exercise on the robot console. The third group did not simulate. All participants took a practical test in the laparoscopy box and their performances were evaluated. Moreover, a pre-test and a post-test were applied, in addition to the VARK and mind styles methods, to assess whether there was a difference in performance between the different learning styles. Results: The practical test scores were relatively homogeneous between the groups and between the Mind Styles and VARK categories, with no significant difference being found between the groups; therefore, it was not possible to demonstrate that learning styles interfered with the results of this study. There was only a significant difference between the pre-test scores of at least one pair of the groups and between the Laparoscopy and Robotics groups, with a p-value of 0.038. Conclusion: There was no statistical significance between learning styles and performance regarding the proposed tasks.

title: Inequalities in child immunization coverage: potential lessons from the Guinea-Bissau case

description: Immunization is one of the main interventions responsible for the decline in under-5 mortality. This study aimed to assess full immunization coverage trends and related inequalities, according to wealth, area of residence, subnational regions, and maternal schooling level in Guinea-Bissau. Data from the 2006, 2014, and 2018 Guinea-Bissau Multiple Indicator Cluster Surveys (MICS) were analyzed. The slope index of inequality (SII) was estimated by logistic regression for wealth quintiles and maternal schooling level as a measure of absolute inequality. A linear regression model with variance-weighted least squares was used to estimate the annual change of immunization indicators at the national level and for the extremes of wealth, maternal schooling level, and urban-rural areas. Full immunization coverage increased by 1.8p.p./year (95%CI: 1.3; 2.3) over the studied period. Poorer children and children born to uneducated mothers were the most disadvantaged groups. Over the years, wealth inequality decreased and urban-rural inequalities were practically extinguished. In contrast, inequality of maternal schooling level remained unchanged, thus, the highest immunization coverage was among children born to the most educated women. This study shows persistent low immunization coverage and related inequalities in Guinea-Bissau, especially according to maternal schooling level. These findings reinforce the need to adopt equity as a main principle in the development of public health policies to appropriately reduce gaps in immunization and truly leave no one behind in Guinea-Bissau and beyond.

title: Control of Mutual Coupling in Microstrip Antenna Design Based on Bio-inspired Algorithms

description: Abstract This paper presents a model that uses bio-inspired optimization algorithms to control of the mutual coupling (MC) in Multiple-Input Multiple-Output (MIMO) systems. The method promotes an increase in the channel throughput and a reduction in the distance among the array elements, searching values less than a half wavelength. A microstrip antenna design, at the frequency of 26 GHz, is used as a prototype for MIMO system testing and performance analysis. Genetic Algorithm (GA) is used to optimize, to determine the antenna physical parameters and to improve its performance. The mutual impedance concept is used to model the MC. The particle swarm optimization (PSO) algorithm is used to optimize the channel throughput and to reduce the distance between the elements. Simulation results show that it is possible to obtain a MIMO system performance improvement of 11.1% in channel throughput, the microstrip width is reduced by 14.5% and the distance among the elements can be reduced by 23.7%, considering the MC.

title: Influence of mode of delivery on satisfaction with hospitalization for childbirth in the study Birth in Brazil

description: Controversial results have been reported on the association between mode of delivery and patient satisfaction. This study investigates which mode of delivery leads to greater satisfaction with hospital admission for childbirth. A cohort study was conducted with data from the Birth in Brazil study, which began in 2011. A total of 23,046 postpartum women were included from a random sample of hospitals, selected by conglomerates with a three level stratification. At the first follow-up, 15,582 women were re-interviewed. Mode of delivery, dichotomized into vaginal or cesarean section, and confounders were collected before hospital discharge. The outcome maternal satisfaction, investigated as a 10-item unidimensional construct, was measured by the Hospital Birth Satisfaction Scale up to six months after discharge. We used a directed acyclic graph to define minimal adjustment variables for confounding. The effect of mode of delivery on satisfaction was estimated using a structural equation model with weighting by the inverse of the probability of selection, considering the complex sampling design. The weight was estimated considering the different sample selection probabilities, the losses to follow-up, and the propensity score, which was estimated in a logistic regression model. The analysis revealed no significant difference in satisfaction with hospitalization for childbirth between respondents who had vaginal delivery and cesarean section in the adjusted analysis (standardized coefficient = 0.089; p-value = 0.056). Therefore, women who had vaginal delivery and cesarean section were equally satisfied with their hospitalization for childbirth.

title: Parkes observations for project P1185 semester 2023APRS_10

description: Ultra-long period neutron stars (ULPNSs) are an emerging class of objects that have sparked interest and curiosity in the fast transient community. Along with standard magnetars, they have been theorised to be potential progenitors of the enigmatic fast radio bursts (FRBs). The MeerTRAP project at the MeerKAT radio telescope is uncovering several magnetar and ultra-long period neutron star candidates, an example of which is PSR J0901-4046 with a period of 76s. Continued long-term monitoring of PSR J0901-4046 has shown it to be potentially transitioning into radio quiescence. The proposed observations will enable us to continue to monitor and characterise the decline in flux density. We have also discovered two new candidates MTP0027 and MTP0068 with periods of ~10 seconds and ~5 seconds respectively. Both sources exhibit magnetar-like pulse morphology and have only been detected in one epoch with MeerKAT. We propose to continue monitoring these sources to re-detect pulses and study their spectro-temporal-polarimetric properties.

title: Elementary school teachers’ knowledge and attitudes toward emergency management of traumatic dental injuries

description: Abstract The consequences of traumatic dental injuries can be even more serious when their emergency management procedures are inadequate. Since traumatic accidents frequently occur at school, it is crucial that teachers be knowledgeable enough to assist an injured child. This study aimed to assess the knowledge and attitudes of the elementary school teachers of a Brazilian city toward dental trauma in permanent teeth, and its emergency practices. A combination of convenience and snowball sampling methods was used. An online questionnaire was distributed through social media, consisting of three parts: demographic characteristics and professional information; previous experiences and attitudes toward dental trauma; teachers’ knowledge of this subject. Descriptive and statistical analyses were carried out. Pearson chi-squared test (p &lt; 0.05) was used. A total of 217 teachers participated in the study. The power of the sample was 95%. Half of the teachers had already witnessed a dental trauma incident involving students, and 70.5% never received any information on the subject. The teachers who were provided previous information were the ones who opted to search for the tooth fragment (p=0.036) in cases of crown fracture, and for the lost tooth (p = 0.025) in cases of avulsion. They were also the ones who chose to wash the tooth in running water (p = 0.018), and look for a dentist in the first 30 or 60 minutes after the trauma (p = 0.026). Most of the teachers assessed did not have adequate knowledge of dental trauma. Having previous information was associated with more assertive practices in trauma management.

title: Degenerative Aortic Stenosis in Women: Challenges and Perspectives

description: Abstract Degenerative aortic stenosis is currently a public health problem. Affecting the elderly population, this pathology has been showing an increasing prevalence as a direct result of the population aging. In this context, women have a greater life expectancy, corresponding to most of the population with degenerative aortic stenosis. Specific characteristics of this pathology in females are present in the diagnosis, pathophysiology, anatomical aspects, imaging and in therapeutic approach. Women present a more severe disease with less valve calcification than men, more concentric ventricular remodeling, higher transvalvular gradients, and less myocardial fibrosis. Less evident symptoms mean that these patients are referred later for surgical or percutaneous therapeutic treatment. The greater comorbidity presented by females and possibly due to the smaller body surface, bring specific aspects that affect the surgery results, leading to higher mortality rates and, more often, the prosthesis-patient mismatch. Percutaneous valve implantation is a good alternative, with better results in females, when compared to surgery, both in the treatment of native valves and in the treatment of a previously implanted bioprosthesis’ dysfunction. The challenges encountered for the treatment of aortic stenosis in women and their possible solutions are described in this article, focusing on the observed difference of aortic stenosis in females and their possible solutions.

title: Public ombudsmen as a transparency tool: legal and federative aspects

description: Abstract The research’s hypothesis is that Brazilian law establishes public ombudsmen as an essential tool for transparency. This paper follows a bibliographic and documentary methodology, aiming to approach the legal aspects of the connection between public ombudsmen and the principle of transparency, besides federative aspects that indicate structuring model to ombudsmen units. The article starts with doctrinal and constitutional elements, such as the “right to be heard”, the “right of access to information” and the “rights of public service users”. It reveals a tendency of the derived constituent power to vote constitutional amendments with clear mention to ombudsman figure. Then, provisions from “Brazilian’s Freedom of Information Act” and “Brazilian’s Defense Code of Public Service Users” point an expressive emphasis on competencies of public ombudsmen. Lastly, some federal guidelines indicate important patterns, such as “Model of Maturity in Public Ombudsman”, a technical document produced by the Brazilian Federal Government Office of the Comptroller General (CGU), as a reference to states and municipalities to structure their own ombudsmen units. Federal patterns are an alternative because Brazilian law does not offer a common legal and national standard for the effective establishment of ombudsmen, which are decisive for the public transparency.

title: On the Reconfigurability of a Singly-Layered Dual-Band Reflectarray for Space Applications

description: Abstract This paper presents a feasibility study of a singlylayered dual-band reflectarray for space applications. The data links should operate simultaneously at K-band downlink frequency band 17.7-20.2 GHz with left-hand circular polarization (LHCP) and at Ka-band uplink frequency band 27-30 GHz with right-hand circular polarization (RHCP). The main aim is to present how a reflectarray can be designed so as to allow reconfigurability of its radiation pattern, especially in terms of beam steering to two different directions. The design is automated by means of a computational tool developed in MATLAB environment interfaced with the electromagnetic simulator CST Studio Suite by means of Visual Basic scripts. Simulation results are presented to demonstrate the efficiency of the proposed computational tool and reconfiguration strategy.
