This study aimed to determine the prevalence of elderly patients with an indication of depression by sex and age group and to identify the factors associated with the indication of depression. Analytical, observational and cross studies were conducted with 850 elderly residents in the rural areas of the municipality of Minas Gerais. For data analysis, we applied the prevalence formula and logistic regression model (p<0.05). The project was approved by the Ethics in Research Human of the Triângulo Mineiro Federal University (Protocol No. 1477). The prevalence of the indicators of depression accounted for 22%, with a greater occurrence among females and individuals aged 6070 years. In females, a higher number of comorbidities and higher functional disability with respect to performing the activities of daily living remained associated with the indication of depression. These results reinforce the need to implement actions to promote health and disease prevention, focusing on depression. Source

Evapotranspiration is the process of water loss of vegetated soil due to evaporation and transpiration, and it may be estimated by various empirical methods. This study had the objective to carry out the evaluation of the performance of the following methods: Blaney-Criddle, Jensen-Haise, Linacre, Solar Radiation, Hargreaves-Samani, Makkink, Thornthwaite, Camargo, Priestley-Taylor and Original Penman in the estimation of the potential evapotranspiration when compared to the Penman-Monteith standard method (FAO56) to the climatic conditions of Uberaba, state of Minas Gerais, Brazil. A set of 21 years monthly data (1990 to 2010) was used, working with the climatic elements: temperature, relative humidity, wind speed and insolation. The empirical methods to estimate reference evapotranspiration were compared with the standard method using linear regression, simple statistical analysis, Willmott agreement index (d) and performance index (c). The methods Makkink and Camargo showed the best performance, with "c" values of 0.75 and 0.66, respectively. The Hargreaves-Samani method presented a better linear relation with the standard method, with a correlation coefficient (r) of 0.88. Source

In addition to neurons, interstitial cells of Cajal (ICC) play an important role in coordinating intestinal motility with a pacemaker function. This study aimed to quantitatively analyze ICC, neurons, and muscular area, the latter to correct for quantitation errors resulting from dilation in case of a megacolon and from the dispersion of ICC that can be attributed to muscular hypertrophy. We analyzed 30 colon samples: ten chagasic megacolon (CM), ten chagasic colons without megacolon (CXM), and ten nonchagasic control patients (NC). We measured the area of muscularis propria and counted the number of neurons of the myenteric plexus in a histological section of an intestinal ring and the number of ICC at the level of the myenteric plexus and circular muscle layer, the latter in a section immunohistochemically stained for CD117. Muscular hypertrophy occurred only in the CM group. Compared to the NC group, we found in the CM group a statistically significant reduction of 80 % in the number of neurons, 60% in the number of ICC in the myenteric plexus, and 38 % in the area of circular muscle. In the CXM group, these numbers were highly variable, and their reduction, less pronounced. We conclude that the number of ICC is significantly reduced in CM patients, and that this might contribute to the pathophysiology of CM. However, the development of CM requires severe denervation, whereas CXM generally exhibits less than 50 % denervation, favoring the hypothesis that the reduction in ICC number is, in part, a consequence of denervation. © Springer-Verlag 2012.

Adhesive restorations have increasingly been used in dentistry, and the adhesive system application technique may determine the success of the restorative procedure. The aim of this study was to evaluate the influence of the application technique of two adhesive systems (Clearfil SE Bond and Adper Scotchbond MultiPurpose) on the bond strength and adhesive layer of composite resin restorations. Eight human third molars were selected and prepared with Class I occlusal cavities. The teeth were restored with composite using various application techniques for both adhesives, according to the following groups (n = 10): group 1 (control), systems were applied and adhesive was immediately light activated for 20 seconds without removing excesses; group 2, excess adhesive was removed with a gentle jet of air for 5 seconds; group 3, excess was removed with a dry microbrushtype device; and group 4, a gentle jet of air was applied after the microbrush and then light activation was performed. After this, the teeth were submitted to microtensile testing. For the two systems tested, no statistical differences were observed between groups 1 and 2. Groups 3 and 4 presented higher bond strength values compared with the other studied groups, allowing the conclusion that excess adhesive removal with a dry microbrush could improve bond strength in composite restorations. Predominance of adhesive fracture and thicker adhesive layer were observed via scanning electron microscopy (SEM) in groups 1 and 2. For groups 3 and 4, a mixed failure pattern and thinner adhesive layer were verified. Clinicians should be aware that excess adhesive may negatively affect bond strength, whereas a thin, uniform adhesive layer appears to be favorable. Source

Sickle cell disease (SCD) is the commonest genetic illness of human beings. In Brazil it is predominant among black and dark-skinned people; every year 3,500 children are born with SCD and 200,000 with the sickle cell trait. In conditions of hypoxia, red blood cells assume the shape of a sickle. Patients may evolve with capillary occlusion causing acute and chronic tissue lesions in organs, which is almost always accompanied by pain. With the purpose of improving knowledge related to the epidemiologic aspects of the illness and how patients cope with it, 47 over 18-year-old patients from the city of Uberaba were studied during home visits. Of these predominantly female patients (59.6%), 78.7% were black, 17% dark-skinned and 4.3% white. In respect to the type of hemoglobinopathy, 63.8% had hemoglobin SS; 17% had hemoglobin SC and 10.6% had sickle beta-thalassemia. The majority (74.5%) lived in poor regions of the city, 42.5% had concluded high school, 38.2% were either retired or did not have any specific profession, 48.9% earned up to one minimum wage and 19.1% did not receive any wages. In respect to their feelings, 38.3% showed they accepted their illness, 21.3% were resentful, 17% were sad and 46.8% said their lives had changed for the worse in relation to work and 31.9% in relation to leisure. It was possible to show with this study that SCD negatively reflects on activities related to work and on the patient's quality of life. Thus, difficulties in coping with the illness, such as poor housing, unemployment and/or badly paid jobs, may be minimized with social and psychotherapeutic accompaniment, which should be made available to every SCD patient.
