Desempenho e background familiar: um estudo no acesso a uma instituição de ensino técnico federal no Brasil

This paper comprises an investigation on the influence of the variable family backgrounds (father school level, mother school level and family income) over the pupil s performance in admissions examination (entrance test or PROITEC) at Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte (IFRN). From that point of view, the main goal of this research is to analyze the influence of the family background as a determiner of the pupil´s performance in the access to Technical and Professional education at IFRN. Secondary data were used from two databases (entrance test and PROITEC) adding up to 19.226 observations to the vacancies offered in the year of 2013. Aiming at achieving the proposed goal, a conceptual model composed of three hypothesis was developed. The results were presented in four stages: stage I presentation of the descriptive statistical results of the two databases; stage II separation of the campi in clusters; stage III analysis of multiple regressions; stage IV analysis of the logistics regressions. Two statistical tests were used to validate the hypothesis: T-test and Wald test. Hypothesis 1 and 2 were confirmed and H3 was refused. The results presented favorable causal connections to the family income and the father school level variables (with bigger effect for fathers with a higher education degree). The mother school level variable did not provide statistical significance for this research. Based on this result, after this work, this institution is to develop a strategic plan to assist in the success rate of students preparing diagnoses in order to diminish the effects of the variables that impacted negatively

An in-house real-time polymerase chain reaction: standardisation and comparison with the Cobas Amplicor HBV monitor and Cobas AmpliPrep/Cobas TaqMan HBV tests for the quantification of hepatitis B virus DNA

This study aimed to standardise an in-house real-time polymerase chain reaction (rtPCR) to allow quantification of hepatitis B virus (HBV) DNA in serum or plasma samples, and to compare this method with two commercial assays, the Cobas Amplicor HBV monitor and the Cobas AmpliPrep/Cobas TaqMan HBV test. Samples from 397 patients from the state of São Paulo were analysed by all three methods. Fifty-two samples were from patients who were human immunodeficiency virus and hepatitis C virus positive, but HBV negative. Genotypes were characterised, and the viral load was measure in each sample. The in-house rtPCR showed an excellent success rate compared with commercial tests; inter-assay and intra-assay coefficients correlated with commercial tests (r = 0.96 and r = 0.913, p < 0.001) and the in-house test showed no genotype-dependent differences in detection and quantification rates. The in-house assay tested in this study could be used for screening and quantifying HBV DNA in order to monitor patients during therapy.

Using autologous platelet-rich plasma for the treatment of complex fistulas

Objective: This study aims to demonstrate the effectiveness and safety of autologous fibrin gel rich in platelet growth factors for the treatment of complex perianal fistulas. Material and methods: Prospective epidemiological study. Patients with complex perianal fistula or perianal fistula mere alteration of continence are included. identification of both holes and the journey, curettage of it and instillation of Vivostat PRF® in the way it is done to observe excess material by OFE. The variables analyzed were: age, sex, use of prior Seton clinic prevalent type of fistula, postoperative complications, fistula closure and impaired quality of life using the SF-36 test (v2). Results: From January 2011 to May 2013 have involved 23 patients, 12 men and 11 women, with an average age of 49 years and a minimum follow-up of 12 months. Two dropped out. 17 patients had low transsphincteric fistulas, 2 and 2 high transsphincteric intersphincteric with impaired continence. The most common symptom is the discharge. Twelve patients had a loose seton (62%), of which nine cured. Of all the patients we have operated the success rate is 62%. No patient developed incontinence after treatment. Only two reported a worse quality of life after surgery. Conclusion: This study demonstrates that there is a clear benefit to the use of Vivostat PRF® as a treatment for complex perianal fistulas. It is a highly reproducible technique with acceptable results and does not produce impairment of continence.

Awake examination versus DISE for surgical decision making in patients with OSA: A systematic review

OBJECTIVE: Traditionally, upper airway examination is performed while the patient is awake. However, in the past two decades, drug-induced sleep endoscopy (DISE) has been used as a method of tridimensional evaluation of the upper airway during pharmacologically induced sleep. This study aimed to systematically review the evidence regarding the usefulness of DISE compared with that of traditional awake examination for surgical decision making in patients with obstructive sleep apnea (OSA). DATA SOURCES: Scopus, PubMed, and Cochrane Library databases were searched. REVIEW METHODS: Only studies with a primary objective of evaluating the usefulness of DISE for surgical decision making in patients with OSA were selected. The included studies directly compared awake examination data with DISE outcome data in terms of possible influences on surgical decision making and operation success. RESULTS: A total of eight studies with 535 patients were included in this review. Overall, the surgical treatment changed after DISE in 50.24% (standard deviation 8.4) cases. These changes were more frequently associated with structures contributing to hypopharyngeal or laryngeal obstruction. However, these differences do not automatically indicate a higher success rate. CONCLUSION: This review emphasized the direct impact of DISE compared with that of awake examination on surgical decision making in OSA patients. However, it is also clear that the available published studies lack evidence on the association between this impact and surgical outcomes

Analysis of Outcome of Intraplueral Streptokinase in Pediatric Empyema Thoracis even in Advanced Stages: A Prospective Study

Background: Empyema thoracis in children causes significant morbidity. Standard treatment of Empyema thoracis includes tube drainage and antibiotics. But the tube drainage often fails. Intrapleural Streptokinase has been used in empyema thoracis with good success rate. Objectives: We evaluated the efficacy of intra-pleural Streptokinase in management of empyema thoracis even in advanced stages. Patients and Methods: A total of 28 patients with empyema thoracis requiring intercostal tube drainage aged zero to twelve years were included in the study who were admitted in Pediatric intensive care unit. 15,000 units/kg of Streptokinase was instilled into the pleural cavity. Response was assessed by clinical outcome, after unclamping and subsequent chest radiography and serial chest ultrasounds. Results: Streptokinase enhanced drainage in all patients with complete resolution of empyema thoracis in 26 patients. Two patients were referred for surgery. Only 7.2% required surgery. Streptokinase was equally effective if started before or after seven days. Conclusions: Intrapleural Streptokinase is the preferred treatment for treating pediatric empyema thoracis even in advanced stages and can avoid surgery.

Different Aspects of General Anesthesia in Pediatric Dentistry: A Review

Context:Most child population is able to undergo dental treatment in the conventional setting. However, some children fail to cope with in-office conscious state and cannot respond to usual management modalities. This review aims to discuss the topic further. Evidence Acquisition: A computerized search in databases PubMed, MEDLINE, EMBASE, Google Scholar and Google were performed using dental general anesthesia related keywords. Original and review English-written articles that were limited to child population were retrieved without any limitation of publication date. The suitable papers were selected and carefully studied. A data form designed by author was used to write relevant findings. Results: Preoperative oral examination and comprehensive evaluation of treatment needs is only possible after clinical and radiographic oral examination. Effective collaboration in dental GA team should be made to minimize psychological trauma of children who undergo dental GA. Before conducting comprehensive dental treatment under GA, the general health of the child and the success rate of procedures provided needs to be accurately evaluated. It is noteworthy that determination of the optimal timing for GA dental operation is of great importance. Providing safety with pediatric dental rehabilitation under GA is critical. Conclusions: Besides criteria for case selection of dental GA, some degree of dental practitioner’s judgment is required to make decision. Pre- and post-operative instructions to parents or caregiver decrease the risk of complications. However, trained resuscitation providers, careful monitoring and advanced equipment minimize adverse outcomes.

Perforación de la membrana timpánica: características clínicas, epidemiológicas y modalidades de manejo. Hospital José Carrasco Arteaga. Cuenca – Ecuador. 2011 - 2015

En el Ecuador la discapacidad auditiva afecta al 5% de la población y pese a ser susceptible de tratamiento es la segunda causa de discapacidad. Muchas de estas patologías alteran el tímpano y disminuyen la capacidad auditiva, afectando la calidad de vida y generando problemas de adaptación y cognición particularmente en niños. El tímpano tiene capacidad regenerativa por lo que la conducta inicial es expectante, sin embargo cuando el defecto no involuciona se inicia el tratamiento. La mayoría de los pacientes recuperan la audición cuando reciben atención médica oportuna. En nuestro medio son escasos los estudios del tema, por lo que el objetivo de este trabajo descriptivo y retrospectivo fue determinar las características clínicas, epidemiológicas y las modalidades de manejo de la perforación timpánica en el Hospital José Carrasco Arteaga de Cuenca durante los años 2011-2015. RESULTADOS: el 50.50% de pacientes fueron mujeres y el 65.20% de la población tuvo entre 20 y 59 años. El 80% de los casos fueron secundarios a infección; la otitis media crónica supurativa se encontró en el 56% de los pacientes y los traumatismos en el 14%. La perforación central fue la más frecuente. El 43.7% de los individuos se realizaron una timpanoplastia, con una tasa de éxito del 58%. CONCLUSIONES: La patología timpánica tiene importantes repercusiones sobre la calidad de vida. Pese a ser una entidad frecuente y susceptible de tratamiento, poco se conoce sobre su manejo. Conocimientos más amplios del tema permitirá al médico general un abordaje apropiado con mejores resultados

Réussite et sélection au premier cycle universitaire au Québec : une analyse multiniveau

L’objectif de ce mémoire est d’étudier les formes de sélectivité scolaire et les facteurs de la réussite dans les programmes de premier cycle universitaire au Québec. En s’appuyant sur les différents écrits sur le sujet, cette recherche présente les différents déterminants de la réussite scolaire ainsi que la sélectivité dans les programmes universitaires québécois. D’un point de vue méthodologique, ce mémoire utilise une base administrative de données longitudinales de l’Université de Montréal constituée de deux générations de cohortes d’étudiants de premier cycle. Sur le plan empirique, nous analysons d’abord la différenciation des programmes de premier cycle en matière de sélectivité pour en dériver un indicateur agrégé de sélectivité. Ensuite, nous étudions les facteurs individuels de réussite en contrôlant l’effet de la cote R dans un modèle multiniveau. L’analyse explicative fait apparaitre deux principaux constats originaux sur les facteurs de réussite, l’un relatif à la cote R et l’autre à l’appartenance de sexe. La cote R influence les chances de réussite des étudiants, mais en raison inverse du niveau de sélectivité à l’entrée. Dans les programmes où la sélection à l’entrée est la plus forte, les taux de diplomation sont les plus élevés et le lien entre la cote R et la note finale est très faible. En outre, le fait d’être un garçon tend à réduire les chances de réussite, mais cet effet négatif disparait quand on tient compte de la cote R ainsi que du programme d’appartenance dans un modèle multiniveau. Si les étudiantes réussissent mieux au niveau du premier cycle universitaire c’est donc surtout parce qu’elles ont eu de meilleures performances scolaires antérieurement et qu’elles ne sont pas dans les mêmes programmes que leurs homologues masculins.

Life history of a native emydid turtle (Malaclemys terrapin centrata) on the remote oceanic islands of Bermuda

Diamondback terrapins (Malaclemys terrapin) are native to the remote oceanic islands of Bermuda and presently inhabit only four small brackish water ponds on a private golf course. The life history of this species is poorly understood on Bermuda and so the aim of this study was to fill these knowledge gaps, to compare the results with what is known from other areas in the North American range, and to inform the development of a local management plan. The results of a mark-recapture census revealed that ca. 100 individuals ≥81 mm straight carapace length live on Bermuda, of which nearly half (48.5%) were considered sexually mature. The population is dominated by females (sex ratio 2.9:1) and annual recruitment over the three year period was found to be extremely low (approximately two terrapins). Female diamondback terrapins in Bermuda nest almost exclusively within a limited number of sand bunkers on the golf course. Nesting commenced in late March or early April and ended in late August. Peak oviposition was observed in May and June. Clutch size averaged 5.1 eggs (range 0-10; SD 2.4) and the incubation period averaged 61.8 days (range 49-83; SD 10.5). Delayed emergence was documented, with 43.8% of the hatchlings remaining in their natal nests over the winter months. The mean annual hatching success rate was determined to be 19% (range 17.6-21; SD 1.9). Radio-telemetry was used to investigate the movements and survivorship of postemergent hatchling diamondback terrapins. The results indicated that mangrove swamps and grass-dominated marshes adjacent to the ponds are important developmental habitats for hatchlings. Yellow-crowned night herons (Nyctanassa violacea) were found to be significant predators of small terrapins during spring emergence. Small aquatic gastropods comprised 66.7% of the faecal samples analysed from the Bermudian population. Scavenged fish and vertebrate animal remains, terrestrial arthropods, polychaete worms and bivalves were consumed in lesser amounts. Sediment from the pond environment was found in 74% of the faecal samples analysed and is believed to have been incidentally ingested while foraging for the small benthic gastropods. Eco-toxicological analyses of the pond sediment, prey and terrapin eggs showed that the Bermudian diamondback terrapins live and feed in wetland habitats characterised by chronic, multifactorial contamination; principally total petroleum hydrocarbons, polycyclic aromatic hydrocarbons and a variety of heavy metals. This study found that some of those contaminants are accumulating in the gastropod prey as well as being transferred to terrapin eggs. This may be reducing the incidence of successful embryonic development for this species in Bermuda and may likely contribute to the observed low hatching rates. These collective findings indicate that the Bermudian population is very vulnerable to local extirpation.

Retratamento endodôntico cirúrgico

Introdução: O presente trabalho tem como tema Microcirurgia Endodôntica sendo esta um tipo de Retratamento Endodôntico Cirúrgico (RTEC). Este tipo de procedimento está indicado em casos de insucesso prévio no Tratamento Endodôntico Não Cirúrgico (TENC). Embora atualmente os índices de sucesso do TENC sejam elevados, existem ainda alguns casos, que não atingem os resultados desejados mesmo realizando corretamente todas as etapas do tratamento. Quando assim é, há necessidade de abordar o sistema de canais radiculares por outra via: recorrer à cirurgia endodôntica e à obturação retrógrada. Objetivos: Esta dissertação tem como objetivo principal abordar uma técnica de Retratamento Endodôntico Cirúrgico: a Microcirurgia Endodôntica. Procedeu-se a uma revisão bibliográfica, analisando literatura que versa o tema, a evolução da técnica, o protocolo cirúrgico em toda a sua extensão, a sua utilidade e aplicabilidade na prática clínica. Materiais e métodos: Na execução desta revisão bibliográfica, os motores de pesquisa on-line utilizados foram os seguintes: b-On, Pubmed, Scielo, Science Direct e Google Académico. Os critérios de inclusão limitaram o uso de artigos publicados entre 2000 e 2016 e nos idiomas de português, inglês e espanhol. Os critérios de exclusão rejeitaram artigos dos quais o teor não teria relevância para a concretização do trabalho e artigos fora dos limites temporais. Conclusão: Na literatura científica, quando a técnica Microcirurgica é comparada com a técnica convencional de RTEC mostra uma taxa de sucesso de excelência e que maioritariamente, os autores defendem que esta deverá ser usada apenas como retratamento, e não isoladamente ou como primeira abordagem terapêutica. Nas últimas décadas, o crescente desenvolvimento científico e tecnológico da cirurgia endodôntica leva à introdução da microcirurgia graças ao recurso da magnificação e iluminação, instrumentos adaptados à nova realidade da cirurgia endodôntica, novos equipamentos e novos materiais associados à retrobturação. É de salientar que este processo cirúrgico é menos invasivo para o paciente e que se obtém um aumento das taxas de sucesso.

Managing large-enrollment courses in hybrid instruction mode

This essay addresses the hitches and glitches in the hybrid instruction system of teaching and learning for large-enrollment courses. This new instructional methodology asks facilitators to redesign their entire traditional teaching and learning practices. The nature of subject to be taught via the hybrid mode further affects the success rate of the modules from the time of inception to launch to actual delivery and completion of the course. The entire process involves undoing the old habits and methodologies and instructors picking up new skills, along with the right motivation to take up the task. The course planning and delivery require a substantial commitment in terms of hours from the instructors catering to large-enrollment courses, along with pursuing their routine roles at the campuses. From the pupil’s perspective, the response varies, as hybrid learning seeks self-discipline and time management skills from the learner. After the initial roadblocks, students enjoy hybrid learning if the course structure and instructions are simple and the course content flexible and varied. We will study the problems and possible solutions to the success of the hybrid teaching–learning system at each stage where large number of students enrolled for a specific course.
