Poveda, Vanessa de Brito;Martinez, Edson Zangiacomi;Galvo, Cristina Maria;
Revista Latino-Americana de Enfermagem , 2012, DOI: 10.1590/S0104-11692012000100024
Abstract: this study analyzed the evidence available in the literature concerning the effectiveness of different active cutaneous warming systems to prevent intraoperative hypothermia. this is a systematic review with primary studies found in the following databases: cinahl, embase, cochrane register of controlled trials and medline. the sample comprised 23 randomized controlled trials. there is evidence in the literature indicating that the circulating water garment system is the most effective in maintaining patient body temperature. these results can support nurses in the decision-making process concerning the implementation of effective measures to maintain normothermia, though the decision of health services concerning which system to choose should also take into account its cost-benefit status given the cost related to the acquisition of such systems.

Robust Linear Regression Models: Use of a Stable Distribution for the Response Data  [PDF]
Jorge A. Achcar, Angela Achcar, Edson Zangiacomi Martinez
Open Journal of Statistics (OJS) , 2013, DOI: 10.4236/ojs.2013.36048

In this paper, we study some robustness aspects of linear regression models of the presence of outliers or discordant observations considering the use of stable distributions for the response in place of the usual normality assumption. It is well known that, in general, there is no closed form for the probability density function of stable distributions. However, under a Bayesian approach, the use of a latent or auxiliary random variable gives some simplification to obtain any posterior distribution when related to stable distributions. To show the usefulness of the computational aspects, the methodology is applied to two examples: one is related to a standard linear regression model with an explanatory variable and the other is related to a simulated data set assuming a 23 factorial experiment. Posterior summaries of interest are obtained using MCMC (Markov Chain Monte Carlo) methods and the OpenBugs software.

Abstract: this study aimed to evaluate the bone mineral density (bmd) of post-menopausal women with previous pre-menopausal hysterectomy including bilateral ovarian conservation compared to a group of non-hysterectomized women with natural menopause. data from a cross-sectional study of 30 pre-menopausally hysterectomized women evaluated in the post-menopause were compared with 102 naturally post-menopausal women, analyzing their respective bone densitometry, measuring the femoral and lumbar spinal bmd. multiple regression analysis of the 132 women showed that age and body mass index (bmi) were heavily associated with femoral and lumbar spinal bmd, bmi directly associated, and age inversely associated with bmd. in addition, 30 hysterectomized women were matched by age and bmi to the 30 non-hysterectomized women, and bone densitometry did not show significant differences in bmd. these findings suggest that pre-menopausal hysterectomy with bilateral ovarian conservation does not appear to cause an additional reduction in bone mass when evaluated in the post-menopausal phase.

Abstract: purpose: to describe sociodemographic characteristics of a group of climacteric women in order to discover the frequency and the variables associated with obesity and android profile of body fat distribution. methods: an observational study was carried out in 518 patients aged 45 to 65 years, in a climacterium outpatient clinic. age, color, menopausal status, duration of menopause, physical activity, smoking status, diet, alcohol intake, personal and family antecedents of arterial hypertension, diabetes mellitus, cardiovascular disease, dyslipidemia and obesity were considered. body mass index and the waist/hip ratio were the dependent variables. for the statistical analysis wilcoxon test, pearson's correlation coefficient, with a 5% level of significance, and multivariate analysis using regression model were used. results: more than two thirds of the participants were nonobese with an android profile and postmenopausal. one fourth had physical activity and were smokers; half reported an inadequate diet and one fifth were alcoholics. patients with an android profile presented higher mean age than women with gynecoid pattern. personal antecedents of obesity, arterial hypertension, diabetes and family history of diabetes were related to obesity and android pattern. postmenopausal status was significantly associated with the android profile. conclusions: the majority of the participants were nonobese with an android profile, white, postmenopausal, sedentary, neither smokers nor alcoholics. the main factors related to obesity and android pattern were personal antecedents of obesity, arterial hypertension, diabetes, family history of diabetes and particularly, postmenopausal status with android profile.
Association between Air Cane Field Burning Pollution and Respiratory Diseases: A Bayesian Approach  [PDF]
Jorge Alberto Achcar, Mayara Piani Luna da Silva Sicchieri, Edson Zangiacomi Martinez
Journal of Environmental Protection (JEP) , 2013, DOI: 10.4236/jep.2013.48A1018

Respiratory diseases and air pollution are the goals of many scientific works, but studies of the relations between these diseases and cane field burning pollution are still not well studied in the literature. In this work, we consider the times between days of extrapolations of the number of daily hospitalizations due to respiratory diseases as our data. To analyze this data set, we introduce different statistical models related to burning focus pollution and their relations with the counting of hospitalizations due to respiratory diseases. Under a Bayesian approach and with the help of the free available WinBUGS software, we get posterior summaries of interest using standard MCMC (Markov Chain Monte Carlo) methods.

Abstract: O transporte rodoviário de passageiros, no Brasil, é um servi o público essencial. O grau de importancia desse servi o pode ser avaliado quando se observa que o transporte rodoviário por nibus é a principal modalidade na movimenta o coletiva de usuários no território nacional. A dinamica desse setor tem demandado a implanta o de uma sistemática ágil de planejamento dos servi os a serem oferecidos aos usuários. Nesse contexto, a gera o de cenários com estimativas do volume de movimenta es é um dos aspectos mais relevantes a serem considerados no planejamento de novos servi os. Neste artigo s o apresentados modelos econométricos de previs o de demanda, que incorporam diversas variáveis sócio-econ micas e as variáveis do modelo gravitacional clássico. No procedimento de calibra o fez-se uso da regress o linear múltipla e da regress o de erros absolutos utilizando os softwares Minitab e EGPA-FR (vers o Evolucionária do Gradiente com Perturba es Aleatórias – com Fórmula de Representa o) no processo de ajuste. O conjunto de dados utilizado na calibra o, correspondente ao ano de 2003, foi obtido por meio de um processo de análise e sistematiza o de um banco de dados, constante dos Anuários (1999 – 2003) disponibilizados pela Agência Nacional de Transportes Terrestres – ANTT. Os resultados finais obtidos neste experimento poder o ser usados pela ANTT para a gera o de cenários com estimativas do volume de movimenta es, o que vem a ser uma contribui o importante no processo de conhecimento da demanda por transporte interestadual por nibus.

Abstract: this study evaluated the effect of blue light emitting diode (led) and quartz tungsten halogen (qth) on the degree of conversion (dc) of an etch-and-rinse single bond adhesive system (sb) and a mixture composed of primer solution and resin bond from clearfil se bond self-etching adhesive system (cb) using fourier transform infrared analysis (ftir). adhesives were applied to potassium bromide pellet surfaces and ftir analyses were performed before and after photo-activation for 10 s with either led (freelight 1 - 400 mw/cm2) or qth (xl 3000 - 630 mw/cm2) light-curing units (n=8). additional ftir spectra were obtained from photo-activated samples stored in distilled water for 1 week. the dc was calculated by comparing the spectra obtained from adhesive resins before and after photo-activation. the results were analyzed by two-way split-plot anova and tukey's test (p<0.05). both adhesive systems exhibited low dc (%) immediately after photo-activation (sb/qth: 18.7 ± 3.9; sb/led: 13.5 ± 3.3; cf/qth: 13.6 ± 1.9; cf/led: 6.1 ± 1.0). the dc of samples light-cured with led was lower than dc of those light-cured with qth, immediately after light curing and after 1 week (sb/qth: 51.3 ± 6.6; sb/led: 50.3 ± 4.8; cf/qth: 56.5 ± 2.9; cf/led: 49.2 ± 4.9). the led curing unit used to photo-activate the adhesive resins promoted lower dc than the qth curing unit both immediately after light curing and 1 week after storage in water.
