INTRODUCTION The objective of this study was to develop a Portuguese version of the World Health Organization fracture risk assessment tool (FRAX®). METHODS All cases of hip fracture occurred at or after 40 years of age were extracted from the Portuguese National Hospital Discharge Register from 2006 to 2010. Age and sex-ranked population estimates and(More)
Germline mutations in the WNK4 gene originate Gordon syndrome or pseudohypoaldosteronism type II, a familial form of hypertension with hyperkalemia and hypercalciuria. In order to elucidate the contribution of WNK4 genetic variants to hypertension and/or osteoporosis, we analyzed 271 control individuals and a cohort of 448 hypertensive and 372 osteoporosis(More)
OBJECTIVE Validate a model of high-fat diet-induced obesity, of low cost, easy reproducibility, that could express characteristics observed in human, and would enable subsequent therapy proposals. MATERIALS AND METHODS Sixteen Swiss mice received a standard diet (DP) or high-fat diet (DH) for 10 weeks. RESULTS Although the DP group had greater water (p(More)
It was introduced in this paper the Optimum-Path Forest for land use classification aiming a better environmental management, using images obtained from CBERS 2B CCD satellite covering the area of the Rio das Pedras watershed, Itatinga City, São Paulo State, Brazil. We also compared the Optimum-Path Forest algorithm with the well known supervised(More)
Research carried out during the past two-decades extended the understanding of actions of vitamin D, from regulating calcium and phosphate absorption and bone metabolism to many pleiotropic actions in organs and tissues in the body. Most observational and ecological studies report association of higher serum 25-hydroxyvitamin D [25(OH)D] concentrations with(More)
Chrysobalanus icaco L. is a medicinal plant popularly known in Brazil as "Grageru" or "Abageru." It is used in African and American continents as medicinal food in the treatment of several diseases, including diabetes. This study used phytochemical screening to determine the antioxidant and α-amylase inhibitor activities of the aqueous extract (AECI) of C.(More)
The presence of chronic lymphocytic leukaemia (CLL) cells in the thyroid gland is most likely due to a secondary involvement by a systemic disease. The reported incidence of CLL involving the thyroid is extremely low, representing about 3-4% of all thyroid lymphoproliferative neoplasm. We report a rare case of CLL presenting initially in the thyroid gland.(More)
Chrysobalanus icaco L. is a medicinal plant present in the Brazilian coastline and known for its hypoglicemic and antioxidant properties. Here, we assessed the beneficial metabolic effects of the aqueous extract of C. icaco (AECI) leaves in diet-induced obese mice. Swiss mice were fed standard chow (SC used as controls) or high-fat diet (HFD) to induce(More)
OBJECTIVE To establish Portuguese recommendations regarding the indication to perform DXA and to initiate medication aimed at the prevention of fragility fractures. METHODS A multidisciplinary panel, representing the full spectrum of medical specialties and patient associations devoted to osteoporosis, as well as national experts in this field and in(More)
Reduced sensitivity to thyroid hormones (RSTH) is a rare disease that affects about 3,000 individuals, belonging to about 1,000 families. It results from reduced intracellular action of thyroid hormones (TH) genetically determined and manifests as persistent hyperthyroxinemia with non-suppressed thyroid-stimulating hormone (TSH). We describe a 67-years old,(More)
