    BACKGROUND: So far there have been no reports on the expression pattern of DAX-1 (dosage-sensitive sex reversal, adrenal hypoplasia critical region, on chromosome X, gene 1) in human breast cells and its relationship to the estrogen receptors, ER-α and ER-β, and the androgen receptor (AR). METHODS: In this study we evaluated, by immunohistochemistry and Western blot analysis, the presence and distribution of DAX-1 in benign breast disease (BBD), in situ carcinoma (CIS), and ductal and lobular breast carcinomas. RESULTS: In BBD and breast carcinomas, DAX-1 was present in both the nuclei and the cytoplasm of epithelial cells, although in infiltrative carcinomas the percentage of nuclear immunoreaction was higher than in CIS. An important relation was observed between DAX-1 and AR expression and between this orphan receptor and nodal status. CONCLUSION: DAX-1 might modify the AR and ER-β intracellular location, and because a direct positive relation between the expression of these three receptors was found it could be assumed that the presence of DAX-1 in neoplastic cells might indicate a possible failure of endocrine therapies

    Introduction: Diabetic foot is one of the most serious complications of diabetes affecting about 150% of all diabetes patients, and it is the leading cause of nontraumatic lower limb amputations. This study presents a sociodemographic and clinical characterization of patients with diabetic foot ulcer indicated for amputation surgery.Methods: A cross-sectional study with 206 patients with type 2 diabetes and a diabetic foot ulcer indicated for amputation surgery. Patients were assessed on sociodemographic and clinical characteristics, pain intensity and pain interference, after answering the Brief Pain Inventory, and on pain descriptors according to the Douleur Neuropathique 4.Results: Most patients were male, with little formal education and a mean age of 66 years. They had been diagnosed with type 2 diabetes for 18 years in average, and diagnosed with diabetic foot ulcer in average 3 years prior to the assessment. About 59% of patients experienced pain in the lower limb that significantly interfered with all areas of their functioning.Conclusion: The social demographic variables play an important role in diabetic foot ulceration. Given that the neuropathic ulcers are more easily preventable, systematic monitoring of patients with neuropathy is important. In patients with neuroischemic foot, strategies to cope or manage more efficiently the pain are paramount. Intervention should be multidisciplinary and take into account sociodemographic and clinical factors, as well as the presence, intensity and interference of pain in the patient's daily life activities and whether the patient has family or caregiver support.Características sociodemográficas e clínicas de doentes com pé diabético. Introdução: o pé diabético é uma das complicações mais graves da diabetes, afetando cerca de 15% dos indivíduos com diabetes, e é a maior causa de amputação de membros inferiores de origem não traumática. Este estudo apresenta uma caracterização sociodemográfica e clínica de doentes com pé diabético indicados para cirurgia de amputação. Método: estudo transversal com 206 doentes com diabetes tipo 2 e pé diabético indicados para cirurgia de amputação. Foram recolhidos dados sociodemográficos e clínicos. Intensidade e interferência da dor foram avaliadas por meio do Brief Pain Inventory e os descritores da dor, pelo Douleur Neuropathique 4. Resultados: a maioria dos doentes era do sexo masculino, com baixa escolaridade e uma média de idade de 66 anos. Apresentava diagnóstico de diabetes tipo 2 havia 18 anos e pé diabético havia 4 anos. Cerca de 59% dos doentes apresentavam dor no membro inferior, interferindo significativamente em todas as áreas de funcionamento. Conclusão: as variáveis sociodemográficas desempenham um papel importante na ulceração do pé diabético. As úlceras neuropáticas são mais facilmente preveníveis; portanto, é importante o acompanhamento sistemático dos doentes com neuropatia. Nos doentes com pé neuroisquêmico, estratégias para lidar/gerir a dor de forma mais eficaz são necessárias. A intervenção deve ser multidisciplinar e considerar os fatores sociodemográficos e clínicos, a presença, intensidade e interferência da dor nas atividades de vida diária do doente, bem como a presença de suporte da família ou de um cuidador.Fundacao para a Ciencia e Tecnologia (FCT)This study was conducted at Psychology Research Centre (PSI/01662), University of MInho, and supported by the Portuguese Foundation for Science and Technology and the Portuguese Ministry of Science, Technology and Higher Education through national funds and co-financed by FEDER through COMPETE2020 under the PT2020 Partnership Agreement (POCI-01-0145-FEDER-007653)info:eu-repo/semantics/publishedVersio
