The problem of contamination by cadmium and lead in Santo Amaro, Brazil, has been studied since 1970 and the severity of this contamination case has been demonstrated by many authors. This study evaluates the persistence of the superficial soil contamination around the metallurgical plant and attempts to correlate the lead and cadmium concentrations to the past atmospheric emissions from the lead plant and with the presence of lead debris under urban road surface and in the backyards of homes. Past emissions still play an important role in soil contamination. In areas without debris, about 30% of the soil samples had lead concentrations above the agricultural use limit of 180 parts per million (ppm) (according to CONAMA 420, 2009), 20% of the samples had concentrations above 300 ppm (maximum for residential use) and 9.6% of the samples had concentrations above 900 ppm (maximum for industrial use). These concentrations are higher close to the chimney of the metallurgical plant. An average lead concentration of 1316 ppm was found in the backyard samples. About 80% of the houses had lead concentrations above 300 ppm and about 50% of the samples had values above 900 ppm, indicating the importance of the lead debris in the contamination scenario. Although a matter of concern, the cadmium concentrations seem to be less problematic than lead at the present time, probably due to the higher mobility of cadmium. The cadmium concentrations in the atmospheric dispersion and backyard samples showed similar trends, while the influence of the lead debris on the soil contamination is less evident. © 2013 Copyright Taylor and Francis Group, LLC.

Objective: To describe the quality of patients' continuity experiences in a population of outpatients receiving postacute rehabilitation care, and to check which elements and types of continuity most strongly determine their satisfaction with care and functional changes. Design: Cross-sectional self-report survey. Setting: Three postacute ambulatory centers in metropolitan areas. Participants: Outpatients (N=218; mean age ± SD, 38.5±11.7y). Interventions: Not applicable. Main Outcome Measures: The questionnaire included experiences regarding aspects of informational (transference of information, accumulated knowledge), management (consistency and flexibility of care), and relational (established relation and consistency of provider) continuity, as well as questions concerning patients' sociodemographic characteristics, satisfaction with care, and global rating change. Results: Respondents indicated more problems in terms of management and relational continuity than in informational continuity. For all patient groups, experiences regarding elements of management continuity (R2=15.3%-22. 4%), followed by relational continuity (R2=14.3%-25.2%), explained most of the variance of satisfaction. Consistency and flexibility of care, together with an established relation, were the most determining elements of satisfaction. Experiences regarding elements of management continuity explained most of the variance of change (18.5%), and flexibility was the most decisive element. Conclusions: Patient satisfaction and functional changes are related with experiences in aspects of management continuity, where there is room for improvement. Measures of management continuity may be promising as indicators of continuity, and they should be prioritized. © 2013 by the American Congress of Rehabilitation Medicine. Source

Joint Bone Spine | Year: 2010

Objective: To perform a detailed magnetic resonance imaging (MRI) analysis of the hands of patients with Jaccoud's arthropathy (JA) secondary to systemic lupus erythematosus (SLE). Methods: The hand with more expressive deformities compatible with JA from a group of SLE patients was examined by 1.5-T MRI. The protocol included coronal, sagittal, and axial turbo-spin-echo images before and after the administration of contrast medium. The presence of synovitis, edema, erosion, cysts, and tenosynovitis in the carpometacarpal, metacarpophalangeal, and proximal interphalangeal joints were scored based on a modified Outcome Measures in Rheumatology recommendations. Results: Twenty SLE patients, (19 women and one man) with median age of 44.7 years (range: 20-76 years), median disease duration of 14.7 years (range: 5-26 years), and median arthritis duration of 13.7 years (range: 4-26 years) were studied. Of the 300 joints evaluated, 202 (67.3%) had some degree of synovitis. Sixteen out of 300 examined joints (5.3%) small areas of erosion were seen in 10 out of the 20 patients (50%). Subchondral bone edema was found in eight out of the 20 (40%) patients or a total of 18 joints (6%). A total of 200 compartments tendons were evaluated, and changes were found in 77 (38.5%) of them. In four out of the 20 patients, the MRI revealed bone cysts. Conclusions: The MRI seems to be a non-invasive diagnostic tool in patients with JA secondary to SLE, and may contribute to understanding the mechanism involved in the development of this deformity. © 2010 Société française de rhumatologie.

Waste Management | Year: 2010

The characteristics of municipal solid waste (MSW) play a key role in many aspects of waste disposal facilities and landfills. Because most of a landfill is made up of MSW, the overall stability of the landfill slopes are governed by the strength parameters and physical properties of the MSW. These parameters are also important in interactions involving the waste body and the landfill structures: cover liner, leachate and gas collection systems. On the other hand, the composition of the waste, which affects the geotechnical behavior of the MSW, is dependent on a variety of factors such as climate, disposal technology, the culture and habits of the local community. It is therefore essential that the design and stability evaluations of landfills in each region be performed based on the local conditions and the geotechnical characteristic of the MSW. The Bandeirantes Landfill, BL, in São Paulo and the Metropolitan Center Landfill, MCL, in Salvador, are among the biggest landfills in Brazil. These two disposal facilities have been used for the development of research involving waste mechanics in recent years. Considerable work has been made in the laboratory and in the field to evaluate parameters such as water and organic contents, composition, permeability, and shear strength. This paper shows and analyzes the results of tests performed on these two landfills. The authors believe that these results could be a good reference for certain aspects and geotechnical properties of MSW materials in countries with similar conditions. © 2010 Elsevier Ltd. Source

Objective: The present study aimed to identify the elements of the vulnerability of infection for HIV/AIDS among adolescents in an Institution of public education. Methods: It is a descriptive-exploratory study with a qualitative approach, with a random sample of 150 students, using a specifi c questionnaire as an instrument for the collection of information, in order to ensure understanding of adolescents vulnerable to AIDS. Results: After data collection, the tabulations were carried out based on the construction of graphs and/or tables that have helped in the understanding of the results which showed that although the majority of adolescents possess correct knowledge in relation to the prevention and/or transmission of AIDS, it is clear, from the data obtained that there is still a high level of vulnerability of students with respect to this disease, since the attitude on the non-use of condoms is generally favorable among the participants of this research on the susceptibility to the disease. Conclusion: After bibliographical study, data collection and analysis, it is concluded that the adolescents know only vaguely about the dangers of the disease and have limited capacity to assimilate and experience the information they received about it. © 2015, Nucleo de Estudos da Saude do Adolescente.
