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 obesidade é uma doença crônica definida como o acúmulo de gordura anormal ou excessiva que pode prejudicar a saúde. Torna-se necessário intervir no seu combate e prevenção, especialmente entre as crianças. A literatura da área indica que, em geral, intervenções apenas com crianças ou com cuidadores, ou com ambos, apresentam resultados favoráveis. Neste estudo foram avaliados os efeitos de instruções, do treino de relato verbal (TRV) e do treino de automonitoração (TA), aplicados com e sem a participação do cuidador principal, sobre o seguimento de regras nutricionais em crianças com obesidade ou sobrepeso. Participaram duas crianças (9 e 11 anos) e suas cuidadoras primárias. O ambiente foi um consultório do ambulatório de psicologia de um hospital universitário. Foram utilizados: Prontuário dos pacientes, Roteiro de entrevista inicial, Inventário de estilos parentais (IEP), Roteiro de entrevista 2, Recordatório 24 horas, Manual informativo sobre obesidade e alimentação saudável, Teste de conhecimentos, Protocolo de orientação nutricional para crianças, Protocolo de automonitoração, Roteiro para análise do protocolo de automonitoração, jogos e brinquedos e Roteiro de entrevista final. O procedimento de coleta ocorreu em 10 sessões distribuídas em aproximadamente 15 semanas e consistiu de análise dos prontuários; entrevista no ambulatório com o cuidador e com a criança para assinatura do Termo de Consentimento Livre e Esclarecido, aplicação do roteiro de entrevista inicial e do IEP; inserção dos participantes em uma de duas condições (Condição 1, apenas a criança [P1] presente; Condição 2, tanto a criança [P2] quanto seu cuidador primário [C2] estavam presentes); aplicação do Roteiro de entrevista 2 seguido da aplicação do Recordatório 24 horas (Linha de Base 1 [LB1]); aplicação do Manual informativo sobre obesidade e alimentação saudável e do Teste de conhecimentos; TRV (Linha de Base 2 [LB2]); TA; entrevista de acompanhamento e entrevista de encerramento. Quanto aos efeitos das instruções, os resultados indicam que P1 manteve a mesma classificação em todos os itens, enquanto P2 melhorou seu desempenho nos itens conhecimento e seguimento das orientações nutricionais e C2 apresentou melhora no conhecimento sobre obesidade ao final do estudo. Os Índices de adesão à dieta obtidos por P2 foram mais elevados do que os obtidos por P1 em todas as fases da pesquisa. Comparando-se a média obtida pelos dois participantes em LB1 e LB2, observou-se aumento de 39,77% indicando mudança com significância clínica após intervenção. A combinação de variáveis nesta pesquisa mostrou-se favorável a ampliação do repertório dos participantes em relação ao comportamento alimentar, tendo como referência o próprio sujeito ao longo do estudo. Os resultados sugerem que há maior eficácia quando crianças e cuidadores são alvo de intervenção.

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.

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...

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)

Sickle cell anemia (SCA) shows a pathophysiology that involves multiple changes in sickle cell erythrocytes, vaso-occlusive episodes, hemolysis, activation of inflammatory mediators, endothelial cell dysfunction, and oxidative stress. These events complicate treatment and culminate in the development of manifestations such as anemia, pain crises and multiorgan dysfunction. The aim of this study was to evaluate, in SCA patients, oxidative stress and antioxidant capacity markers, correlating them to treatment with hydroxyurea (HU), β-globin haplotypes and glutathione S-transferase polymorphisms (GSTT1, GSTM1 and GSTP1), in comparison to a control group (CG). The study groups were composed of 48 individuals without hemoglobinopathies (CG), SCA patients treated with HU [AF (+HU), N = 13] and untreated SCA patients [AF (-HU), N = 15], after informed consent. The groups were analyzed using cytological, electrophoretic, chromatographic and molecular methods and information from medical records. The GSTM1 and GSTT1 polymorphisms were determined by multiplex PCR, while the GSTP1 polymorphism by PCR-RFLP. Biochemical parameters were measured using spectrophotometric methods [TBARS, TEAC and catalase (CAT) and GST activities] and a chromatographic method [glutathione (GSH)]. The fetal Hb (Hb F) levels observed in the SCA (+HU) group (10.9%) confirmed the already well-described pharmacological effect of HU, but the SCA (-HU) group also had high Hb F levels (6.1%), which may have been influenced by genetic factors not targeted in this study. We found a higher frequency of the Bantu haplotype (48.2%), followed by the Benin (32.1%) and also Cameroon haplotypes, rare in our population, and 19.7% of atypical haplotypes. The presence of Bantu haplotype was related to higher lipid peroxidation levels in patients, but also, it conferred a differential response to HU treatment, raising Hb F levels in 52.6% (P = 0.03). The protective effect of Hb F was confirmed, because the increase in their levels resulted in a 41.3% decrease in lipid peroxidation levels (r = -0.74, P = 0.0156). The genotypic frequency of the GST polymorphisms observed was similar to that of other studies in the Brazilian population, and its association with biochemical markers revealed a significant difference only for the GSTP1 polymorphism, where patients with genotype V/V showed higher GSH and TEAC levels (P = 0.04 and P = 0.03, respectively) compared to patients with genotype I/I. The TBARS levels were about five to eight times higher in the SCA (+HU) and SCA (-HU) groups, respectively, compared to controls, and HU produced a 35.2% decrease in lipid peroxidation levels in the SCA (+HU) group (P < 0.0001). Moreover, the SCA (+HU) group showed higher TEAC levels when compared to CG (P = 0.002). We did not find any significant difference in GST activity between the groups studied (P = 0.76), but CAT activity was about 17 and 30% lower in SCA (+HU) and SCA (-HU) groups, respectively (P < 0.00001). Plasma GSH levels were ~2 times higher in SCA patients than in the control group (P = 0.0005) and showed a positive correlation with TBARS levels, confirming its antioxidant function. HU treatment contributed to higher CAT activity and TEAC levels and lower lipid peroxidation, and its pharmacological effect showed a “haplotype-dependent” response. These findings may contribute to elucidating the potential of HU in ameliorating oxidative stress in SCA subjects.

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.
