A influência da cultura organizacional no processo de inovação: o caso da águia sistemas de armazenagem em Ponta Grossa, Paraná

Abstract: O presente artigo tem como objetivo verificar se os processos de inovacao desenvolvidos na Empresa Aguia Sistemas de Armazenagem S.A., localizada no municipio de Ponta Grossa – Parana sao influenciados pela cultura organizacional da empresa. Para tanto, construiu-se uma revisao da literatura sobre cultura organizacional e inovacao. Trata-se de uma pesquisa descritiva, com abordagem metodologica qualitativa, com dados quantitativos que complementam a analise de conteudo, a partir da aplicacao de tres instrumentos de pesquisa, fundamentados nos estudos de Godoy (2009), orientado pela Professora Dra. Doris L. Pecanha: Questionario de Caracterizacao da Empresa de Base Tecnologica e Processos de Inovacao; Escala de Cultura da Inovacao – ECI; e Roteiro para Entrevista com Gestor de P&D. Os resultados evidenciaram que a cultura organizacional influencia profundamente os processos de inovacao da industria, verificando-se a existencia de uma cultura de inovacao solidificada na empresa.

Índice de risco odontológico para pacientes pré- transplante renal submetidos à hemodiálise Index of dental risk for pretransplant renal hemodialysis patients

Abstract: Introduction: Patients with chronic renal failure (CRF) have low immunity due to the medicines they use, their clinical condition and the treatment itself. For this reason, any infection, including oral infections, present a higher risk for this group of patients. Objective: To develop and implement an index of dental risk according to the severity of the lesions present in the oral cavity of pretransplant hemodialysis patients. Material and methods: The most prevalent infectious processes in the oral cavity were classified according to their severity, and an index of dental risk was developed for pretransplant renal patients. Thirteen patients of the Pro-Renal Foundation of Curitiba were selected and submitted to clinical and radiographic examination for the determination of the index of dental risk proposed in this study. Results: According to the pathologies diagnosed, the index of dental risk of the patients can be classified as low, medium or high, which indicates the need for dental treatment prior to renal transplantation. 38% of the 13 patients submitted to clinical and radiographic examination were classified as high-risk patients.

Pesticides in a case study on no-tillage farming systems and surrounding forest patches in Brazil.

Abstract: With the growing global concern on pesticide management, the relationship between its environmental recalcitrance, food security and human health has never been more relevant. Pesticides residues are known to cause significant environmental contamination. Here, we present a case study on long-term no-tillage farming systems in Brazil, where Glyphosate (GLY) has been applied for more than 35 years. GLY and its main breakdown product, aminomethylphosphonic acid (AMPA) were determined in topsoil (0–10 cm) samples from no-tillage fields and nearby subtropical secondary forests by high-performance liquid chromatography coupled with a fluorescence detector. In addition, the presence of carbamates, organochlorines, organophosphates and triazines were also screened for. GLY and AMPA were present in all soil samples, reaching values higher than those described for soils so far in the literature. A significant decrease for AMPA was observed only between the secondary forest and the farm's middle slope for site B. GLY and AMPA were observed respectively at peak concentrations of 66.38 and 26.03 mg/kg soil. GLY was strongly associated with forest soil properties, while AMPA associated more with no-tillage soil properties. Soil texture was a significant factor contributing to discrimination of the results as clay and sand contents affect GLY and AMPA retention in soils. This was the first study to report DDT and metabolites in consolidated no-tillage soils in Brazil (a pesticide fully banned since 2009). Based on human risk assessment conducted herein and the potential risk of GLY to local soil communities, this study offers a baseline for future studies on potential adverse effects on soil biota, and mechanistic studies.

Low bone mineral density in brazilian patients at diagnosis of celiac disease

Abstract: BackgroundLow bone mineral density is considered an extra-intestinal manifestation of celiac disease with reduced bone mass, increased bone fragility, and risk of fractures. Celiac disease is considered a condition at high risk for secondary osteoporosis and the evaluation of bone density is very important in the clinical management of these patients.ObjectiveThe present study aimed to investigate bone alterations in celiac patients from Curitiba, South Region of Brazil at diagnosis, correlating the findings with age and gender.MethodsPatients who were included in the study were attended to in a private office of the same physician from January 2009 to December 2013. The diagnosis of celiac disease was done through clinical, serological and histological findings. All data were collected from the medical charts of the patients. After the diagnosis of celiac disease, evaluation for low bone mineral density was requested by dual-energy X-ray absorptiometry (DEXA). DEXA bone densitometer was used to estimate low bone mineral density at the lumbar spine and femur.ResultsA total of 101 patients, 82 (81.2%) female and 19 (18.8%) male subjects, with mean age of 39.0±3.03 years were included. At celiac disease diagnosis, 36 (35.6%) were younger than 30 years, 41 (40.6%) were between 31 and 50 years, and 24 (23.8%) were older than 50 years. Among the evaluated patients, 69 (68.3%) presented low bone mineral density, being 47% with osteopenia and 32% with osteoporosis. Patients who were older than 51 years and diagnosed with celiac disease presented low bone mineral density in 83.3% (20/24) of the cases. As expected, age influenced significantly the low bone mineral density findings. Among women, low bone mineral density was present with high frequency (60%) from 30 to 50 years. In patients diagnosed older than 60 years (n=8), all the women (n=5) and two of the three men had osteoporosis.ConclusionThis study demonstrated that 69% of Brazilian patients with celiac disease at diagnosis had low bone mineral density, being more frequent in women older than 50 years.
