The association between periodontal disease and the development of atherosclerosis has been studied. The systematic review of literature aims to evaluate the association between periodontal disease and sub clinical atherosclerosis. A literature search of the PubMed, Scopus, LILACS, BBO, Cochrane Library and Scielo bibliographic databases was conducted using the following descriptors: "periodontal disease", "periodontitis", "carotid", and "therosclerosis". Articles were excluded if they: presented abstracts written in languages other than Portuguese, English and Spanish; experimental studies; did not contain data testing the degree of association between periodontal disease and subclinical atherosclerosis; did measure the extent of periodontal disease by parameters other than the clinical examination; did not measure the carotid artery intima-media wall thickness by ultrasonography; and covered specific population groups. The studies design, measurement protocols and reported data were compared. A total of 63 papers identified only 10 studies that met the inclusion criteria: 1 longitudinal study, 6 cross-sectional, and 3 case control studies. There was a wide heterogeneity between the studies regarding the methods of measuring periodontal disease and atherosclerosis outcomes. The conclusion is that periodontal infections are strongly associated with the development of subclinical atherosclerosis, however the mechanisms involved on the pathogenic process remain unknown.

Objective: To evaluate the quality of life (QoL) and potential QoL determinants in patients with clinically isolated syndrome (CIS). Methods: Eighteen CIS patients and eighteen controls were submitted to QoL evaluation with Functional Assessment of Multiple Sclerosis QoL instrument (FAMS). Cognition was evaluated with specific battery tests; Anxiety and depression with Beck Anxiety (BAI) and Depression (BDI) Inventories and Neurological disability with Guy's Neurological Disability Scale (GNDS). Results: There was a significant difference in QoL between CIS patients and controls. CIS patients had worse performance in Paced Auditory Serial Addition 2 seconds (p=0.009) and fluency tests (p=0.0038). There was a significant difference in BAI (p=0.003), but no significant difference in BDI between patients and controls. There were significant correlations between QoL measure and verbal fluency and Stroop's test. Conclusions: Cognition, but not anxiety, depression and disability, was associated with reduced quality of life. Source

Due to the overwhelming number of mass movements which takes place in the urban area of Ouro Preto (MG), a study of accidents occurred between 1988 and 2004 has been developed, based on the city's Fire Brigade reports. It has then been possible to elaborate a map highlighting the most critical areas surrounding the city. Such areas were then tagged as low, medium and high risk. Another stage presented in the work was the correlation between landslides and rainfall. To obtain this, rain data had to be collected at a local plant. An equation has been obtained correlating the fallen rain on the landslide day and the accumulated rain from the five previous days which occurred before the accident. Once the equation was established, the amount of rain prompting landslides could be estimated. Based on this, a civil defense plan for the city is greatly recommended. Source

In this research the Health Care Waste of Group A (Resíduos de Serviço de Saúde-RSS), collected from six hospitals in Vitoria (ES), Brazil, was quantified and classified according with ANVISA's Resolution RDC no 306/2004. The waste was packaged without segregation and afterwards separated by groups and subgroups, with the following results/percentages: 57% Group D-common; 41% Group A-biological risk; 1.5% Group B-chemical risk; and 0.05% Group E-sharps. The apparent bulk density was 106.2 kg/m3. The average production rate of this mixture was 2.68 kg per occupied bed daily. By separating the mixture of the RSS from group D, the average production rate of Group A changed to 1.15 kg per occupied bed daily, reducing incineration costs by 58%. By segregating Groups B, D, E and subgroup A4, the average production rate changed to 0.18 kg per occupied bed per day with a reduction of 93% in incineration costs. Source

The austenitic-ferritic stainless steels present a better combination of mechanical properties and stress corrosion resistance than the ferritic or austenitic ones. The microstructures of these steels depend on the chemical compositions and heat treatments. In these steels, solidification starts at about 1450°C with the formation of ferrite, austenite at about 1300°C and sigma phase in the range of 600 to 950°C.The latter undertakes the corrosion resistance and the toughness of these steels. According to literature, niobium has a great influence in the transformation phase of austenitic-ferritic stainless steels. This study evaluated the effect of niobium in the microstructure, microhardness and charge transfer resistance of one austenitic-ferritic stainless steel. The samples were annealed at 1050°C and aged at 850°C to promote formation of the sigma phase. The corrosion testes were carried out in artificial saliva solution. The addition of 0.5% Nb in the steel led to the formation of the Laves phase.This phase, associated with the sigma phase, increases the hardness of the steel, although with a reduction in the values of the charge transfer resistance.
