1. Testing the consumption-based CAPM using the stochastic discount factor
Abstract This article investigates the problem of optimal intertemporal consumption in the CCAPM setup from a new empirical perspective. The econometric analysis is based on use of the equality between the stochastic discount factor (SDF) and the marginal rate of intertemporal substitution of consumption, which in the CCAPM is equivalent to the Euler equatio

2. Validation of the Brazilian version of the child pain catastrophizing scale and its relationship with a marker of central sensitization
Abstract Objectives The Pain Catastrophizing Scale-Child version (PCS-C) allows to identify children who are prone to catastrophic thinking. We aimed to adapt the Brazilian version of PCS-C (BPCS-C) to examine scale psychometric properties and factorial structure in children with and without chronic pain. Also, we assessed its correlation with salivary leve

3. Prevalence and risk factors for post-traumatic stress, anxiety, and depression in sepsis survivors after ICU discharge
Objective: Sepsis survivors present a wide range of sequelae; few studies have evaluated psychiatric disorders after sepsis. The objective of this study was to define the prevalence of and risk factors for anxiety, depression and post-traumatic stress disorder (PTSD) symptoms in sepsis survivors. Method: Anxiety, depression and post-traumatic stress sympto

4. Environmental and socioeconomic analysis of malaria transmission in the Brazilian Amazon, 2010–2015
ABSTRACT OBJECTIVE To analyze the environmental and socioeconomic risk factors of malaria transmission at municipality level, from 2010 to 2015, in the Brazilian Amazon. METHODS The municipalities were stratified into high, moderate, and low transmission based on the annual parasite incidence. A multinomial logistic regression that compared low with medi

5. Characterization of factors determining the consumption of pork in the Metropolitan Area of the Valley of Mexico
ABSTRACT The objective of the present study was to learn the characteristics that affect pork meat consumption in the Valley of Mexico Metropolitan Area. Qualitative regression models (Logit and Probit) were used, and a survey of 440 consumers was carried out. The results showed that the sample of pork consumers was made up mostly of women (91.1%) aged betwe

6. 3-D finite element analysis of the effects of post location and loading location on stress distribution in root canals of the mandibular 1st molar
Abstract Objective The purpose of this study was to evaluate, by using finite element analysis, the influence of post location and occlusal loading location on the stress distribution pattern inside the root canals of the mandibular 1st molar. Material and Methods Three different 3-D models of the mandibular 1st molar were established: no post (NP) – a

7. The mechanism of drug interactions of a selected antiarrhythmic drug with metformin, in different animal models
ABSTRACT This study was carried out to understand the influence of a selected antiarrhythmic drug on the pharmacodynamics and pharmacokinetics of an antidiabetic drug in animal models. Pharmacodynamic and pharmacokinetic responses were determined by measurements of blood glucose and serum insulin and serum metformin to drug interactions between disopyramide

8. Marginal and internal fit of zirconia copings obtained using different digital scanning methods
Abstract The objective of this study was to evaluate the marginal and internal fit of zirconia copings obtained with different digital scanning methods. A human mandibular first molar was set in a typodont with its adjacent and antagonist teeth and prepared for an all-ceramic crown. Digital impressions were made using an intraoral scanner (3Shape). Polyvinyl

9. Evaluation of the adaptation of zirconia-based fixed partial dentures using micro-CT technology
The objective of the study was to measure the marginal and internal fit of zirconia-based all-ceramic three-unit fixed partial dentures (FPDs) (Y-TZP - LAVA, 3M-ESPE), using a novel methodology based on micro-computed tomography (micro-CT) technology. Stainless steel models of prepared abutments were fabricated to design FPDs. Ten frameworks were produced wi

10. The occurrence of dental caries is associated with atherosclerosis
OBJECTIVE: Previous studies have suggested that marginal periodontitis is a risk factor for developing atherosclerosis. The objective of this study was to determine whether caries may also be associated with atherosclerosis. METHODS: The computed tomography data sets of 292 consecutive patients, 137 women and 155 men with a mean age of 54.1±17.3 years, wer

11. Modelos multivariados binários com funções de ligação assimétricas / Multivariate binary regression models with asymmetric link functions
Conjuntos de dados com respostas multivariadas aparecem frequentemente em pesquisas em que os dados são provenientes de questionários. Exemplos mais comuns são pesquisas de opinião, mais especificamente, pesquisas de marketing em que a preferência do consumidor em potencial é avaliado: pelo produto, marca, preço, praça, promoção e etc. Um tipo pesq

12. Técnicas de diagnóstico para modelos lineares generalizados com medidas repetidas / Diagnostics for generalized linear models for repeated measures data with missing values
A literatura dispõe de métodos de diagnóstico para avaliar o ajuste de modelos lineares generalizados (MLGs) para medidas repetidas baseado em equações de estimação generalizada (EEG). No entanto, tais métodos não contemplam a distribuição binomial nem bancos de dados com observações faltantes. O presente trabalho generalizou os métodos já des
