Objectives: We attempt to investigate a possible association between periodontal disease (PD) and mental disorders (MD) in a population of Brazilian Police. Study Method: From a total study population consisting of 803 policemen, 345 police officers were obtained by a sample calculation using the finite population correction who were randomly selected in Montes Claros, Minas Gerais, Brazil. Patients who had been prescribed steroids or those diagnosed with diabetes and cardiovascular diseases were excluded from this study. The General Health Questionnaire (GHQ-12) was used to assess mental disorders. Odds ratios (ORs) for periodontal diseases severity and their respective 95% confidence intervals (CIs) were estimated. The risk of advanced scores in Clinical Attachment Level (CAL) and Community Periodontal Index (CPI) were estimated using Poisson Regression analyses. Results: Only smoking and age were associated with severity in CAL and CPI index. No relation between MD and PD was observed even in different positions within the police department. Conclusions: It was not observed relation between GHQ 12 and the incidence of Periodontal Disease in a Brazi-lian Police population. Classical factors like age and smoking, however, were associated with CAL and CPI index higher scores in this population. © Medicina Oral S. L. Source

To compare the prevalence of orofacial manifestations between patients with and without sickle cell anemia and to investigate the distribution of such events in patients with sickle cell anemia by sex and age. A cross-sectional study was conducted in which 330 subjects divided into two groups (a group of individuals with sickle cell anemia and a healthy control group) were examined. It was observed that patients with sickle cell anemia had a significantly higher prevalence of previous mental nerve neuropathy (P = .000) and delayed tooth eruption (P = .006) than patients without the disease. Regarding the distribution of orofacial manifestations in patients with sickle cell anemia by sex and age, the only statistical associations were between the prevalence of previous mental nerve neuropathy and sex (P = .023) and previous mandibular pain and age (P = .019). This study found that sickle cell anemia is associated with the prevalence of previous mental nerve neuropathy and delayed tooth eruption. Moreover, previous mental nerve neuropathy is more frequent among females with sickle cell anemia, and previous mandibular pain is more frequent among individuals older than 21 years of age with sickle cell anemia. Further studies using a methodology similar to the one in this study are necessary considering the scarcity of studies using this approach. Source

This study aimed at determining which educational models have been applied to the activities health education. This is a review of literature on the topic Models of Education and Health Education, using as reference contemporary books of specialists in the field of education and journals on such topics available in major databases. The results showed that the Traditional Model of health education aims to transfer the knowledge and experience of the educator, giving a paramount importance to the content taught, hoping that the students absorb unchanged and faithfully reproduce. The model based on dialogue understands the in health education as a process of awareness, change and transformation, characterized by a philosophy of emancipatory subject. Source

Macaúba (Acrocomia aculeata) is a palm of economic importance, widely distributed in natural forests from Mexico to Uruguay. We analyzed the genetic diversity of populations of macaúba (A. aculeata) in the northern region of the State of Minas Gerais, Brazil. Young leaves from 10 macaúba individuals encompassing 49 genotypes of macaúba were collected from Montes Claros, Itacambira, Brasília de Minas, Mirabela, and Grão Mogol. After extraction and amplification of samples, the amplified fragments were separated by electrophoresis. We found high levels of genetic diversity within the populations. Genetic diversity indices were high, except in the Itacambira and Mirabela populations. Results show that Mirabela and Itacambira populations can require conservation strategies because they present lower values of genetic diversity. Source

Use of molecular markers can be limited by the high cost and extensive time required for their development. Transfer of simple sequence repeat (SSR) markers reduces the cost and time limitations and has allowed the use of these markers in a larger number of species. We tested 11 SSR markers previously developed for Anacardium occidentale on A. humile. The 11 loci were successfully amplified in A. humile. All loci were polymorphic and generated a mean of 5.4 alleles per locus. The observed heterozygosity was lower than the expected heterozygosity under Hardy-Weinberg equilibrium for most loci, with mean values of 0.463 and 0.696, respectively. The endogamy coefficients were positive and significant for seven loci. However, the combined probability of paternity exclusion was high, and the combined probability of genetic identity was low. None of the pairs of loci were in linkage disequilibrium. The informative power of these loci demonstrates that they are suitable for studies of diversity and genetic structure of natural populations of A. humile. In addition, the loci are suitable for estimating gene flow between populations, assessing species crossing preferences, and performing interspecific comparisons. Source
