Evaluation of obstructive sleep apnea in obese patients scheduled for bariactric surgery

PURPOSE: To evaluate the frequency of obstructive sleep apnea (OSA) in obese patients scheduled for bariatric surgery and their identification for risk of OSA by Berlin Questionnaire (BQ) and excessive daytime sleepiness by Epworth Sleepiness Scale (ESS). METHODS: Fifty nine patients were evaluated by BQ and ESS. Out of these individuals, 35 performed a full-night sleep study using a type 3 portable monitoring (PM). The questionnaire results were compared for gender and BMI. The presence and severity of OSA was correlated with gender and both questionnaires. RESULTS: 94.75% of the respondents presented high risk for OSA by BQ and 59.65% presented positivity by ESS. Taking into account the AHI> 5 per hour for OSA diagnosis, all of them presented OSA, average AHI of 45.31±26.3 per hour and 68.6% have severe OSA (AHI>30). The male patients had a higher AHI (p<0.05). There was a positive correlation between the positivity in both questionnaires as well as the severity of OSA measured by AHI (p<0.05). CONCLUSION: The frequency and severe obstructive sleep apnea in the studied group is high. The Berlin Questionnaire and Epworth Sleepiness Scale had a positive correlation with the diagnosis of OSA in the group studied.

Efficacy of an Oral Appliance for the Treatment of Obstructive Sleep Apnea

Purpose: The aim of this study was to validate the use of a mandibular repositioner appliance (MRA) to treat obstructive sleep apnea (OSA) and primary snoring, comparing polysomnographic and Epworth Sleepiness Scale (ESS) data obtained prior to and during MRA treatment. Materials and Methods: Sixty-three patients who presented with different degrees of OSA severity or primary snoring were fitted to a PM positioner between 2009 and 2011. The diagnosis was established by a polysomnogram (PSG) prior to treatment and after 6 months to verify the efficacy of MRA therapy. Subjective daytime sleepiness was evaluated by ESS questionnaire prior to treatment and at the follow-up. Results: Patients were divided into primary snoring and OSA groups. For the primary snoring group, PSG variables did not show significant results, except for a decrease in snoring. For the OSA group, the mean apnea-hypopnea index (AHI) was reduced from 23.0 +/- 11 to 5.3 +/- 4.0 and median ESS reduced significantly from 13.0 to 8.5. Complete response (AHI < 5) was found in 25 (40%) patients and partial response (AHI <= 10) in 27 (43%) patients. Conclusion: The findings validate the efficacy of the adjustable PM positioner for the safe treatment of OSA.

Avaliação da estabilidade da capacidade de produção de cefamicina C por Streptomyces clavuligerus

Streptomyces clavuligerus é uma importante espécie industrial que produz múltiplos compostos de interesse clínico, destacando-se o antibiótico cefamicina C (CefC) e o ácido clavulânico (AC), um potente inibidor de b-lactamases produzidas por bactérias resistentes a penicilinas e cefalosporinas. Sabe-se que situações limite como subculturas sucessivas, forma inadequada de armazenamento das células, variações bruscas de condições de cultura, podem causar deleções de mais de 25% dos genes de Streptomyces sp que, embora muitas vezes não comprometam a sobrevivência do micro-organismo, acarretam perdas na capacidade produtiva. Neste trabalho, investigou-se a estabilidade da linhagem selvagem S. clavuligerus ATCC 27064 quanto à produção de CefC variando-se condições do inóculo utilizado nos cultivos submersos de obtenção do antibiótico. As fermentações foram realizadas em frascos agitados (28ºC, 260 rpm) e as amostras coletadas em 48 e 72 horas do caldo fermentativo foram analisadas quanto ao pH, biomassa (massa seca a 105ºC por 24 h) e CefC foi determinada por bioensaio de difusão em ágar (bactéria-teste Escherichia coli ESS 2235). Foi selecionado o micro-organismo melhor produtor por meio de screening, e o que apresentou a melhor produção de CefC e os menores desvios com relação à média foi utilizado para preparar novos lotes de células: ampolas de micélios liofilizados e criotubos contendo 108 esporos.mL-1 . Observou-se que a capacidade produtiva foi afetada quando foram utilizadas subculturas do micro-organismo original. A realização do screening mostrou-se eficiente na seleção de colônias superiores em termos de produção volumétrica, sendo recomendada a realização de tal procedimento periodicamente para manutenção de uma linhagem com maior potencial produtivo...

O trabalho dos catadores de materiais recicláveis de Presidente Prudente, São Paulo: um estudo aplicado na COOPERLIX e na coleta seletiva municipal

This work focuses on analyzing the organization of the Workers Cooperative Recyclable Products of Presidente Prudente (COOPERLIX) and selective collection of municipal service. Aiming to analyze the issue of solid waste and the work of collectors of recyclable materials in an organized Economic Development Outreach (ESS). Throughout the work was carried out theoretical approaches on the issue of solid waste, the precarious work of scavengers, some laws, among others, were conducted several field studies over the years 2011 and 2012 in COOPERLIX, with the realization meetings and debates on various subjects; tools were also used Geographic Information Systems mainly in the production of selective collection of municipal map, now at 100% of the urban area of Presidente Prudente. Finally, we carried out a comprehensive analysis of the situation of the productive and financial COOPERLIX during those two years, checking their capability and weaknesses

Aplicação do ciclo rankine orgânico alimentado termicamente pela queima da casca do arroz e resíduos de madeira

With the growing world energy demand mainly from developing countries like Brazil, Russia, India and China, the search for efficient sources of energy becomes a challenge for the coming years. Among the most widely used alternative sources, biomass is the one that grows in a more pronounced way. This study will assess the real possibility of having it as a heat source in an Organic Rankine Cycle, which employ heat transfer fluids as working fluids instead of water. From a regional data collection in agricultural production and their potential rice production and the resulting husk was defined as more appropriate. The availability of husks together with an amount of eucalyptus wood, provided by a company in the region on a monthly basis, were analyzed, and the low participation of the wood was discarded by the thermal contribution of little significance. Based on this, it was established the calorific value of fuel for thermodynamic calculations and the cycle to be used. It was then carried out the choice of working fluid from the literature and their availability in the library of software used for the simulations, the Engineering Equation Solver - ESS. The fluid most appropriate for the burning of biomass, Octamethyltrisiloxane (OMTS), was not included in the software and so the R227ea and R134a were selected. After the initial parameters modeling definition, as condensing temperature, efficiency and live steam conditions, the simulations were performed, and only the R227ea remained within the feasible thermodynamic and technological ranges. With this fluid the turbine power output was 265.7 [kW] for a scenario of 24 hours/day burning, 800.3 [kW] to biomass burning for 8 hours/day and 2134 [kW] for burning only 3 hours/day. The thermal efficiency of the cycle remained in the range of 6%, and for plants operating with the most... (Complete Abstract click eletronic access below)

Autoerotismo em sala de aula: o que pensam, como reagem e dizem fazer os professores?

Realizing the need for a discussion on the topic of sexuality in schools, and especially teachers training, this qualitativ e study investigated the teachers' reports about autoeroticism of their students in the cl assroom: what they thin k, how they react, say and do in their teaching prac tice. Nine teachers participated of bot h sex, who were interviewed for further projective content ana lysis. The results show that teachers, although they consider this an important work with their stud ents they expr ess difficulty talking about it, even de parting from indicating his own views and not based on theories, thus evidencing the deficiency in thei r training to deal with sexual education in school. We conclude that teachers still perceive sexuality from myths and taboos, especially on autoeroticism, and in that sens e, it is important to invest in academic training teachers to develop in a pedagogical way, continuous and systematic sexual education projects in school.
