Development of mev-eds methodology for forensic analysis on automotive headlights

A comparative study between three automotive headlights (conventional, halogen, and HID lamp) using scanning electron microscopy coupled with energy dispersive spectrometry (SEM-EDS) is described. Results show the possibility of conducting topographic and qualitative analysis of automotive light bulbs from vehicles involved in traffic accidents on the basis of similarities between the waste glass material left on the filaments. This should provide evidence as to whether the bulbs were energized at the time of the accident.

Mapeamento de regiões de ativação cerebral durante tarefas deglutórias por imagens de ressonância magnética funcional

INTRODUÇÃO: A deglutição é um processo fisiológico complexo que acontece por uma sequência motora automática, regulada por um complicado mecanismo neuromotor e neuromuscular que é iniciado de maneira consciente e é resultado da integridade anatômica e funcional de diversas estruturas faciais. É de extrema importância para a nutrição do organismo como um todo. Um dos maiores desafios no campo das ciências é identificar os substratos neurais de comportamentos fisiológicos, incluindo esse processo de deglutição. O desenvolvimento da tecnologia em neuroimagem funcional nos últimos anos está provocando um rápido avanço no conhecimento de funções cerebrais, o que resultou numa explosão de novos achados em neurociência. OBJETIVO: Mapear as regiões de ativação cerebral durante o fenômeno da deglutição por meio do exame de ressonância magnética funcional. MÉTODO: Participaram do estudo quatro indivíduos do sexo feminino, com idade entre 18 e 30 anos, sem alterações neurológicas, estruturais e alimentares. Após a aprovação da Instituição (Clínica Lobo), do Comité de Ética e Pesquisa do Instituto de Ciências da Saúde (ICS) e a aprovação escrita de cada paciente através do termo de consentimento livre e esclarecido, foram submetidos a quatro provas deglutórias, utilizando a técnica de ressonância magnética funcional. RESULTADOS: Foi possível a determinação da ativação dos hemisférios cerebrais e cerebelares e as especificas áreas que os compõem. Mesmo com uma amostragem pequena, os resultados das análises individuais mostraram padrões de acordo com a literatura, conjuntamente com dados novos. DISCUSSÃO: O cerebelo é responsável pela coordenação da ação motora e manutenção da harmonia dos movimentos, posição e equilíbrio do bolo alimentar; o bolbo raquidiano juntamente com o tronco cerebral constitui o centro de atividades reflexas que controla funções ou respostas orgânicas automáticas como a deglutição; o mesencéfalo é a parte do encéfalo que coordena a informação visual; o tálamo encaminha quase todo o tipo de informação sensorial para as zonas específicas do córtex cerebral; o hipotálamo, importante na experimentação das sensações de prazer, regula as funções homeostáticas do corpo, gustação, olfação, salivação, interagindo com o sistema nervoso autônomo e o sistema límbico está ligado ao controle e direção das reações emocionais, sob a ação da amígdala, no processamento de odores e no armazenamento de conteúdos da memória, aqui através do hipocampo. CONCLUSÃO: O ato de deglutir é um processo complexo, ativando muitas áreas cerebrais, dentre elas podemos destacar a gustativa, mental/visual e a olfativa e que é iniciado muito antes dos processos mecânicos envolvidos, conforme demonstrado pelas áreas corticais e subcorticais ativadas. A área olfativa foi a mais notadamente destacada nas imagens colhidas pela Rmf.

A percepção da doença de Alzheimer pelos estudantes da F.F.C. Júlio de Mesquita Filho da UNESP, Marília

Alzheimer’s disease (AD) accounts for approximately 56% of all cases of dementia. The present study aimed to report the perception of AD by students of Physiotherapy, Speech Therapy and Occupational Therapy from Faculty of Philosophy and Science “Julio de Mesquita Filho” – UNESP – Marília, with regard to the symptoms, diagnosis and treatment, between 2011 and 2012. The questionnaire with open and closed questions was administered to 101 students, using as a criterion for exclusion those who refused to answer the survey and / or not signed the informed consent form. After the questionnaire application, the answers have undergone quantitative analysis, checking which information and concepts about Alzheimer’s disease these students acquired during the undergraduate years. The data shows that although students have knowledge about the signs and symptoms of the disease, few mention the importance of family, the caregiver and the relationship of the disease with dependence that commonly reaches this population.

Eventos adversos em terapia medicamentosa em Unidade de Terapia Intensiva - UTI

Due to the complexity and instability of clinical conditions of ICU patients, the drug therapy applied in this type of environment requires a combination of several prescribed drugs, which is a favorable condition for drug interaction, toxic synergism and possible iatrogenia. In the possible universe of ICU occurrences, this study aimed at identifying and evaluating the incidence of adverse events in drug therapy at the Intensive Care Therapy Service (SETI) in wards I and II. It is a cross-sectional, descriptive, prospective and quantitative study conducted from August to September, 2011 in the Intensive Care Service of the Botucatu School of Medicine University Hospital - UNESP. The population consisted of fifteen clinical nurses, including those in the Improvement and Volunteer Internship Programs, who contributed to the investigation after signing an informed consent form and according to approval by the Research Ethics Committee number 10711/CE - FMB. The data were entered on a form and analyzed. Results showed that, on average, 8.9% of events/day occurred, and the highest frequency was observed on August 04, 2011. 63% and 22% were respectively observed in the morning and afternoon shifts, and 15% in the night shift. 48% of these were due to administration time errors, followed by drug prescription and dispensation errors, with percentages of 22% and 18%, respectively. Antibiotics showed the highest frequency of adverse events - 18%, which was followed by 13% for anticoagulant, 11% for antiemetic and 10% for antiulcerative drugs. As regards the occurrence of adverse events related to hospitalization time, the highest frequency occurred in patients who were hospitalized for 10 days. Concerning the ratio between reported events and the number of items in the prescription, the highest frequency of events was related to prescriptions with 20 items...

Checklist de cirurgias da OMS: análise da segurança e comunicação da equipe cirúrgica de um hospital escola

WHO has launched the “Safe Surgery Saves Lives” program with the purpose to reduce damage to surgical patients and define safety standards specifically in order to reduce such patients’ morbi-mortality by providing surgery teams and hospital managers with orientation about the standards of safe surgery and a uniform service evaluation instrument for national and international surveillance. Hence, this study aimed at applying the WHO safe-surgery checklist to the surgical specialties of a university hospital and evaluating the team’s opinion about the influence of its application on the safety of surgical process and on the team’s interpersonal communication. It was a descriptive, analytical, qualitative field study conducted in the surgery facilities of a university hospital in a public establishment in São Paulo state. The checklist was applied to eight surgical specialties, resulting in a total number of 30 surgeries. Its application was conducted by the researcher in three phases: Sign in, Time out, Sign Out. Next, one member of the surgery team was invited to voluntarily participate in the study by signing an informed consent form and answering guiding questions. Thirty members of the surgery team participated in the study. Bardin’s Content Analysis Method was used to organize and analyze the data. As regards the safety provided by the checklist, the following thematic categories emerged: “It reduces risk and possible complications”; “It standardizes conducts and reviews safety steps”; “It allows for better understanding of the process”; and “It provides safety to the team as a whole”. The category “It is not included in the institution’s routine” emerged from the subjects’ statements when they understood that, in this form, the checklist does not provide safety to surgical procedures. As regards communication, two thematic categories emerged: ...(Complete abstract click electronic access below)

Modelo de conductancia hidráulica de la dentina humana ex vivo

The main objective of this work was to mount and test an experimental model to measure the hydraulic conductance of ex vivo dentin. Seventeen healthy third molars, with indication of extraction of healthy donors aged between 15 and 30 years were obtained by informed consent. After cleaning them, disinfecting them, including them in resin epoxy and cutting them, there were 17 samples of dentin, corresponding to a disk of resin with a coronal section of tooth showing the dentin exposed on both sides of it. Three machines to measure the hydraulic conductance of the dentin were assembled according to the description of the model of Pashley. Samples were installed in a Chamber of diffusion, connected by using silicone tubes to a graduated transfer pipette and a 20cm water column. Through the displacement of a bubble of water in the inside of the pipette, the hydraulic conductance of each sample was measured 3 times on the 14th, 21st, 28th and 35th day post extraction. The data were tabulated and analyzed statistically. There is no SS difference in the rate of flow of a measured sample in the three machines (p=0.5937). There is no SS difference in measurements of the hydraulic conductance of 13 samples of human dentin measured in days 14, 21, 28 and 35 postextraction (p=0.0704). It is possible to mount an experimental model to study the hydraulic conductance of dentin ex vivo, based on the model of Pashley. The model seems to be reliable, but more research is needed in order to validate its reliability.
