PURPOSE\backslashr\backslashnThe aim of this study was to evaluate the effects of intravitreal treatment with bevacizumab (IVB) compared with triamcinolone (IVT) in patients with macular edema due to … branch retinal vein occlusion (BRVO) depending on the duration of BRVO.\backslashr\backslashnMETHODS\backslashr\backslashnA total of 65 BRVO patients were divided into 2 subgroups: group 1 with early treatment (≤ 3 months since onset of BRVO) and group 2 with late treatment (\textgreater 3 months since onset). For the two groups IVB was injected into 17 eyes as early (IVB1) and into 18 eyes as late (IVB2) treatment. For comparison IVT was injected into 14 eyes as early (IVT1) and into 16 eyes as late (IVT2) treatment. Best corrected visual acuity (BCVA) and central retinal thickness (CRT) were analyzed at baseline, 1, 3 and 6 months after treatment.\backslashr\backslashnRESULTS\backslashr\backslashnIn both subgroups a significant improvement of BCVA and CRwas observed. After 6 months, for patients with early treatment, IVB1 showed better results than IVT1 (BCVA: p = 0.008, CRT: p = 0.021). In the late treatment no significant differences between IVT2 and IVB2 were found.\backslashr\backslashnCONCLUSIONS\backslashr\backslashnBevacizumab and triamcinolone significantly improved BCVA and CRT in patients with BRVO. The best BCVA was found if bevacizumab was used as early treatment. In the late treatment no significant differences between bevacizumab and triamcinolone were observed.

Body surface assessment with 3D laser-based anthropometry: reliability, validation, and improvement of empirical surface formulae.
Genetical Statistics and Systems Biology

Abstract (Expand)

PURPOSE Body surface area is a physiological quantity relevant for many medical applications. In clinical practice, it is determined by empirical formulae. 3D laser-based anthropometry provides an easy …y and effective way to measure body surface area but is not ubiquitously available. We used data from laser-based anthropometry from a population-based study to assess validity of published and commonly used empirical formulae. METHODS We performed a large population-based study on adults collecting classical anthropometric measurements and 3D body surface assessments (N = 1435). We determined reliability of the 3D body surface assessment and validity of 18 different empirical formulae proposed in the literature. The performance of these formulae is studied in subsets of sex and BMI. Finally, improvements of parameter settings of formulae and adjustments for sex and BMI were considered. RESULTS 3D body surface measurements show excellent intra- and inter-rater reliability of 0.998 (overall concordance correlation coefficient, OCCC was used as measure of agreement). Empirical formulae of Fujimoto and Watanabe, Shuter and Aslani and Sendroy and Cecchini performed best with excellent concordance with OCCC \textgreater 0.949 even in subgroups of sex and BMI. Re-parametrization of formulae and adjustment for sex and BMI slightly improved results. CONCLUSION In adults, 3D laser-based body surface assessment is a reliable alternative to estimation by empirical formulae. However, there are empirical formulae showing excellent results even in subgroups of sex and BMI with only little room for improvement.

Brain Arousal Regulation in Carriers of Bipolar Disorder Risk Alleles.
LIFE Adult

Abstract (Expand)

OBJECTIVES: Recent genome-wide association studies identified a number of chromosomal risk loci for bipolar disorder (BD, 'manic-depressive illness'). According to the vigilance regulation … model, the regulation of brain arousal (referred to as 'vigilance') when assessed via EEG is an emerging biomarker linked to the pathogenesis of manic and depressive episodes. On this basis, the present study aimed to assess whether carriers of BD risk alleles differ in brain arousal regulation. METHODS: Healthy participants of the population-based Leipzig Health Care Study (LIFE) underwent a 20-min eyes-closed resting EEG paradigm. Brain arousal was assessed applying the computer-based Vigilance Algorithm Leipzig (VIGALL). The primary sample (n = 540) was genotyped for ten of the most reliable BD risk variants, of which two qualified for replication (n = 509). RESULTS: Primary sample analyses revealed Bonferroni-adjusted significance for rs1006737 in CACNA1C (encoding a calcium channel subunit), with risk allele carriers exhibiting relatively steep brain arousal declines. Further, carriers of two risk alleles of rs472913 at 1p32.1 showed generally lower brain arousal levels for the duration of the resting paradigm. However, both associations failed replication. CONCLUSION: Although our initial findings are in line with the vigilance regulation model and convincing in view of the previously reported notable role of ion channelopathies in BD, our results do not provide consistent evidence for a link between BD risk variants and brain arousal regulation. Several between-sample differences may account for this inconsistency. The molecular genetics of brain arousal regulation remain to be clarified.
