Bone marrow cells of swine: collection and separation

Bone marrow is a source of stem cells for greater and easier access, which is widely studied as a provider of hematopoietic and mesenchymal cells for various purposes, mainly therapeutic by the advances in research involving cell therapy. The swine is an animal species commonly used in the pursuit of development of experimental models. Thus, this study aimed to standardize protocol for collection and separation of bone marrow in swines, since this species is widely used as experimental models for various diseases. Twelve animals were used, which underwent bone marrow puncture with access from the iliac crest and cell separation by density gradient followed by a viability test with an average of 98% of viable cells. Given our results, we can ensure the swine as an excellent model for obtaining and isolation of mononuclear cells from bone marrow, stimulating several studies addressing the field of cell therapy.

Percepção do médico sobre pagamento por desempenho no gerenciamento de doenças cardiovasculares: o caso de uma operadora de plano de saúde

Desde os anos 50, os fatores de risco para as doenças cardiovasculares passaram a ser valorizados. O gerenciamento de doenças cardiovasculares (PGC) busca a construção da autonomia e melhoria da qualidade de vida dos pacientes. Em alguns países, para alcançar esses objetivos, tem sido apontada a utilização de programas de pagamento por desempenho (PPP) aos médicos como um dos elementos de melhoria nos processos e nos resultados dos pacientes e na condição de remuneração. O objetivo deste estudo é analisar o ponto de vista dos médicos sobre a implantação dos pagamentos por desempenho vinculados ao PGC em uma operadora de plano de saúde. Trata-se de investigação de caráter qualitativo, do tipo estudo de caso, apresentando entrevistas semiestruturadas com médicos participantes ou não do PGC, em setembro de 2009, tendo como referência as ações implantadas em 2008. Foram entrevistados 23 médicos (14 homens e 09 mulheres). Como resultado foi observado que o incentivo financeiro é reconhecido pelos médicos como importante, mas não determinante da inclusão de pacientes no PGC. O principal motivo apresentado foi a organização do cuidado, no qual o paciente é mais bem acompanhado e controlado, e o trabalho médico, avaliado segundo parâmetros preestabelecidos. O PGC e o PPP têm potencial de transformação do cuidado em saúde. O trabalho multidisciplinar e a maior produtividade nos atendimentos no consultório foram os principais efeitos positivos identificados. Outros estudos são necessários para acompanhar a evolução e os efeitos do pagamento por desempenho no trabalho médico.

Occurrence of bipolar spectrum disorder and comorbidities in women with eating disorders

Abstract Background Eating disorder (ED) patients often have comorbidities with other psychiatric disorders, especially with mood disorders. Although recent studies suggest an intimate relationship between ED and bipolar disorder (BD), the study on a broader bipolar spectrum definition has not been done in this population. We aimed to study the occurrence of bipolar spectrum (BS) and comorbidities in eating disorder patients of a tertiary service provider. Methods Sixty-nine female patients diagnosed with anorexia nervosa, bulimia nervosa, or eating disorder not otherwise specified were evaluated. The assessment comprised the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), clinical criteria for diagnosis of the Zurich bipolar spectrum. Mann–Whitney tests compared means of continuous variables. The association between categorical variables and the groups was described using contingency tables and analyzed using the chi-square or Fisher's exact test. The level of significance alpha was set at 5%. Results The results showed that 68.1% of patients had comorbidity with bipolar spectrum, and this was associated with higher family income, proportion of married people, and comorbidity with substance use. The ED with BS group showed higher rates of substance use comorbidity (40.4%) than the ED without BS group (13.6%). Discussion These results showed that the bipolar spectrum is a common comorbidity in patients with eating disorders and is associated with correlates of clinical importance, notably the comorbidity with substance use. Due to the pattern of similarity between the groups with and without comorbid bipolar spectrum in relation to various outcomes evaluated, the identification of comorbidity can be difficult. However, the precise diagnosis and careful identification of clinical correlates may contribute to future advances in treating these conditions. Further studies are necessary to evaluate the association of other clinical correlates and its possible causal association.
