BACKGROUND Direct-acting antivirals have revolutionized hepatitis C treatment, also for patients with chronic kidney disease (CKD), but some controversy exists regarding the use of sofosbuvir (SOF) in patients with glomerular filtration rate (GFR) less then 30 mL/min. OBJECTIVE To evaluate the efficacy and safety of these regimens for hepatitis C treatment of patients with CKD and after renal transplantation, as well as the impact of SOF on renal function in non-dialysis patients. METHODS All patients with hepatitis C and CKD or renal transplant treated with direct-acting antivirals at a referral center in Brazil between January 2016 and August 2017 were included. Efficacy was evaluated based on viral load (HCV RNA) and a sustained virological response (SVR) consisting of undetectable RNA 12 and/or 24 weeks after the end of treatment (SVR12 and SVR24) was defined as cure. Safety was determined by adverse events and ribavirin, when combined, was administered in escalating doses to all patients with GFR less s percentage decreased to 1.1% after SOF use. Only 0.5% and 1.6% of the patients progressed to AKIN II and AKIN III elevation, respectively. CONCLUSION The direct-acting antivirals were safe and efficacious in CKD patients treated with SOF-containing regimens, with the observation of high SVR rates, good tolerability and few severe adverse events. The combination with ribavirin increased the risk of anemia and the administration of escalating doses seems to be useful in patients with GFR less then 60 mL/min. In patients with GFR less then 30 mL/min, SOF had no significant renal impact, with serum creatinine returning to levels close to baseline after treatment.BACKGROUND Inflammatory bowel disease encompasses pathological entities, the main being Crohn's disease and ulcerative rectocolitis. Both are characterized by chronic inflammation of the intestine. It affects young people of active age, compromising the situation of those patients, especially their quality of life, experiencing a strong deterioration in their clinical condition, from physical to social and emotional aspects. OBJECTIVE Evaluate the quality of life of patients assisted in the multidisciplinary reference outpatient clinic for the treatment of inflammatory bowel diseases, through sociodemographic data and specific questionnaires on the disease, evaluating the intestinal and systemic symptoms and the social and emotional aspects. Make a comparison between the two scales used to obtain the data. METHODS A cross-sectional study was carried out in which patients diagnosed with inflammatory bowel disease were evaluated and observed at a reference outpatient clinic for treatment from May 2017 through Dects were those with the lowest scores among the parameters of the Inflammatory Bowel Disease Questionnaire; physical (40.6±44.4) and emotional aspects (49.5±46.0) had lower scores among the Short Form-36 domains. The correlation between the two questionnaires proved to be significant. CONCLUSION The clinical profile of the patients followed the characteristics of distribution and prevalence of these diseases. The impact of diseases on quality of life was observed in several aspects, especially those related to psychological components. Multidisciplinary follow-up, as well as psychological, social, nutritional and educational support should be considered important determinants to maintain or improve the quality of life of these patients.OBJECTIVE To compare the ways of evaluating arithmetic skills in Brazilian children with ADHD by combining three validated neuropsychological tests and determining whether they are sensitive to the methylphenidate treatment. METHODS Forty-two children (9‒12 years old) participated in the present study 20 were children with ADHD (DSM-IV) and 22 were age-matched controls. A classification criterion was used for each test separately and one, for their combination to detect the presence of arithmetic difficulties at two time points baseline (time 1); and when children with ADHD were taking 0.3‒0.5 mg/kg of methylphenidate (time 2). The study also assessed children's subtraction performance, combining parts of these tests. RESULTS Separately, the tests were only sensitive to differences between groups without medication. However, by combining the three neuropsychological tests, we observed a difference and detected a reduction in arithmetic difficulties associated with the methylphenidate treatment.  https://www.selleckchem.com/products/vcmmae.html  The same effects were found in subtraction exercises, which require a borrowing procedure. CONCLUSIONS The present study detected arithmetic difficulties in Brazilian children with ADHD and the effects of methylphenidate. Given this improvement in sensitivity, combining tests could be a promising alternative when working with limited samples.Professor Andrew John Lees, from the National Hospital for Neurology and Neurosurgery, a neurological hospital in Queen Square, London, UK, has contributed in a stupendous way to the development of the field of movement disorders in Brazil, with a constant and intense participation in numerous congresses and scientific meetings of this specialty since 1983.Methylophiopogonanone A (MO-A), a homoisoflavonoid extracted from Ophiopogon japonicus, has been shown to attenuate myocardial apoptosis and improve cerebral ischemia/reperfusion injury. However, the hypolipidemic effects remain unknown. This study was performed to investigate a potential hypolipidemic effect of MO-A in hyperlipidemia rats, as well as its underlying mechanism of action. A rat model of hyperlipidemia was induced by a high-fat diet (HFD). Animals were randomly divided into three groups (n=8/group) normal control group (NC), HFD group, and HFD+MO-A (10 mg·kg-1·d-1) treatment group. The effects of MO-A on serum lipids, body weight, activity of lipoprotein metabolism enzyme, and gene expression of lipid metabolism were evaluated in HFD-induced rats. In HFD-induced rats, pretreatment with MO-A decreased the body weight gain and reduced serum and hepatic lipid levels. In addition, pretreatment with MO-A improved the activities of lipoprotein lipase and hepatic lipase in serum and liver, down-regulated mRNA expression of acetyl CoA carboxylase and sterol regulatory element-binding protein 1c, and up-regulated mRNA expression of low-density lipoprotein receptor and peroxisome proliferator-activated receptor α in the liver.
