“Recent studies demonstrated that diffusion tensor imaging (DTI) can provide information regarding white matter integrity of the corpus callosum (CC). In this study, DTI parameters were compared between cocaine dependent subjects (CDs) and non-drug using controls (NCs) in midsagittal CC. Fer-1 molecular weight DTI images were acquired from 19 CDs and 18 age-matched NCs. The midsagittal CC was segmented into: genu, rostral body, anterior midbody, posterior midbody, isthmus, and splenium. Linear mixed models analyses showed that, relative to NCs, CDs had lower fractional anisotropy (FA), higher radial diffusivity

(lambda(perpendicular to)) and higher mean diffusivity (D(m)) in the isthmus; higher X-L and D., in the rostra] body: and lower FA in the splenium. After including mass of lifetime alcohol use in the mixed model analysis of covariance (ANCOVA) as a covariate, significant between group differences in X, in the FOStral body and isthmus remained. These results Suggest that alterations in),, in the rostral body and isthmus were mainly due to cocaine use, consistent with previous studies showing that cocaine may alter myelin integrity. Between group differences in FA in the isthmus and splenium, and D, in the rostral body and isthmus became non-significant after inclusion

of alcohol use as a covariate. This is suggestive of alcohol influencing these values, or may be related to the decreased degrees of freedom for these effects. Consistent with clinical data of greater severity of drug use in smoked versus intranasal NSC23766 in vivo cocaine, subjects who smoked cocaine showed lower FA and higher lambda(perpendicular to) compared to intranasal CDs.

“Deranged lipid metabolism is a common complication of chronic kidney disease (CKD). Uremia, and metabolic and endocrinological Fludarabine concentration disturbances associated with uremia, as well as the high prevalence of comorbidities,

wasting and inflammation in CKD patients, all play their role in promoting and modifying CKD-associated dyslipidemia. However, the exact pathomechanisms leading to lipid disorders are still poorly understood. Similarly, the impact of lipid disturbances on patient outcome is unclear. Many studies in dialysis patients have documented the, so called, ‘reverse epidemiology’, with low plasma cholesterol being an apparent risk factor for mortality. Potential explanations for this phenomenon include confounding by wasting and comorbidities, reverse causation, and also causal relationships with hypocholesterolemia having a direct impact on poor outcome. To elucidate the question of ‘reverse epidemiology’ some novel approaches have been introduced, for example, Mendelian randomization and time-dependent conditional survival analysis.
