BACKGROUND: Declined renal function is associated with physical function impairment and frailty in a graded fashion. This study aimed to examine the relationship between renal function, frailty and physical performance with mortality in older patients with diabetes, while also determining their combined effects on patient outcome. METHODS: A retrospective longitudinal study was conducted in elderly patients with diabetes. Kidney disease staging was based on clinical practice guidelines of the International Society of Nephrology, and chronic kiney disease (CKD) was defined as urinary albumin to creatinine ratio (UACR) > 30 mg/g, persistent reduction in estimated glomerular filtration rate (eGFR) below 60 mL/min per 1...

Aim: Wilson's disease (WD) presents with different phenotypes. Neurologic and liver involvement in WD are well documented. Few reports demonstrated cardiac and vascular involvement. Several studies showed an association between serum copper levels and atherosclerosis. Although WD is the prototype disease of copper metabolism, atherosclerosis has not been studied yet. The aim of this study is to assess aortic stiffness in WD. Materials and Methods: Aortic pulse wave velocity (PWV), augmentation pressure (AP), augmentation index (AIx), central aortic systolic, diastolic, mean, and pulse pressures were measured using SphygmoCor (AtCor Medical) device in 32 patients with WD and 24 healthy controls...

OBJECTIVE: To present the process of transcultural adaptation of the Richmond Compulsive Buying Scale to Brazilian Portuguese. METHODS: For the semantic adaptation step, the scale was translated to Portuguese and then back-translated to English by two professional translators and one psychologist, without any communication between them. The scale was then applied to 20 participants from the general population for language adjustments. For the construct validation step, an exploratory factor analysis was performed, using the scree plot test, principal component analysis for factor extraction, and Varimax rotation...

The present study was conducted to evaluate the antioxidant, anti-inflammatory, and antiproliferative activities of organic fractions from Cystoseira sedoides (Desfontaines) C. Agardh . Various fractions of C. sedoides (chloroform (F-CHCl3), ethyl acetate (F-AcOEt), and methanol (F-MeOH)) were screened for total phenol content, as well as antioxidant activity, using the stable radical 1,1-diphenyl-2-picrylhydrazyl (DPPH), and assays for determining the reducing power of these fractions. The anti-inflammatory properties of these fractions were assessed using the carrageenan-induced rat paw oedema model...

INTRODUCTION: Plasmapheresis (PP) is a therapeutic apheresis technique used in the treatment of various renal and systemic diseases with varying degrees of proven clinical efficacy. OBJECTIVE: To review our experience with PP at the Hospital Universitario de Canarias, focused on effectiveness and safety results in different disease groups. MATERIAL AND METHODS: A retrospective-descriptive study of patients treated with PP from 01/01/2006 to 31/12/2009 at the hospital...

Autosomal dominant polycystic kiney disease is a hereditary systemic disorder, characterized by the developement of cysts, mainly in the kidney and liver, also with gastrointestinal and cardiovascular abnormalities. It affects 4 to 6 million people wordwide and accounts for end-stage renal disease in 7-10% of dialysis patients. The genetic penetrance is 100%, all affected individuals develop renal cysts until 70 years of age, and because of a great renal function reserve only about 50% of patients develop some degree of renal failure until the age of 60...

OBJECTIVE: To investigate the prevalence by age, response to different therapies and outcome in newly diagnosed idiopathic thrombocytopenic purpura (ITP). METHODS: ITP patients who were hospitalized from July 1992 to December 2006 and followed up with telephone were retrospectively analyzed. RESULTS: 103 patients with ITP were investigated. The time of follow-up was between 2 months to 15years. Male:female = 35:68. The rate of patients over 60 years old was 34...

Brain glucose metabolism was studied in paralyzed, ventilated rats given electroconvulsive shock (ECS) under normocapnic and hypercapnic conditions. Brains were obtained with a freeze-blowing apparatus. Rates of glucose utilization were determined with [2-14C]glucose and [3H]deoxyglucose as tracers. In normocapnic rats, ECS caused a large increase in the rate of glycolysis to 5--6 mumol/g/min. Brain lactate levels increased three- to fourfold. The stimulation of glucose metabolism was reflected in decreased brain glucose 6-phosphate concentration as early as 2--3 s after ECS...

The effects of hyperlactatemia on cerebral glucose metabolism of normoglycemic 20-day-old rats were studied in animals breathing air or 20% CO2:21% O2:59% N2. Sodium lactate or sodium bicarbonate were given intraperitoneally, together with a mixture of [3H]deoxyglucose and [2-14C]glucose. Animals were sacrificed in a freeze-blowing apparatus at intervals of 2-15 min after injection. Blood lactate levels in the lactate-injected rats were 4-6 mM. Hyperlactatemia caused a gradual decline in the brain rate of glucose utilization in air-breathing animals to 50-70% of control rates...
