zepine treatment but not significantly so (RR 2.53, 99% CI 0.27 to 23.85; fixed-effect model; 6 studies; moderate-certainty evidence). AUTHORS' CONCLUSIONS Oxcarbazepine might be effective at reducing seizure frequency when used as an add-on for drug-resistant focal epilepsy. The efficacy outcomes - 50% or greater seizure reduction and seizure freedom - were derived from low-certainty evidence. We are, therefore, uncertain whether the estimated effect size is representative of the true effect. In contrast, the evidence for median percentage seizure reduction and treatment withdrawal were of moderate certainty thus, we are fairly certain of the effect estimates' reliability. Overall, we are unsure of the true efficacy of oxcarbazepine, but have concerns about its tolerability. check details © 2020 The Cochrane Collaboration.

METHODS We compared, by analysis of variance, the values of seven OA Doppler variables (peak systolic velocity, second systolic peak velocity [P2], mean velocity, end diastolic velocity, resistance index [RI], pulsatility index [PI], and peak ratio) of 31 women with preeclampsia and 33 women with gestational hypertension vs those of 227 women without HDP. The prognostic value of these variables in relation to the occurrence of HDP was evaluated by the area under the curve (AUC) receiver operating characteristic curve. RESULTS All OA Doppler variables except RI and PI showed significant (P less then  .5) differences between groups. After adjustment for confounders, only P2 was an independent predictor of HDP (P less then  .001), with an AUC of 0.76. The best cut-off point for predicting HDP was P2 ≥ 21.4 cm/s, with sensitivity 69%, specificity 78%, positive likelihood ratio 3.1, negative likelihood ratio 0.4, positive predictive value 47%, and negative predictive value 90%. P2 improved the predictive ability of a model based on clinical variables, incrementing AUC from 0.77 to 0.84 in the final model containing clinical and Doppler variables. CONCLUSION The elevation of OA P2 in the second trimester of pregnancy is an independent predictor of hypertensive disorders, and improves the discriminatory ability of clinical markers. © 2020 Wiley Periodicals, Inc.OBJECTIVES Asymmetrical behavior patterns are observed in many animal species, but the potential adaptive significance of lateralization and the evolutionary forces driving it remain unclear. Most laterality studies have focused on a single species, which makes interspecies comparisons difficult. The aim of this study was to examine differences in the strength and direction of lateralization in multiple lemur species when engaged in a standardized, novel cognitive task. MATERIALS AND METHODS We assessed laterality in seven lemur species at the Duke Lemur Center when using a novel puzzle-box. We recorded which hand opened the apparatus door and which hand picked up the food reward. We also recorded whether the mouth was used for either action instead of the hands. We then calculated handedness indices (HI), z-scores, and mouth-use rates. RESULTS Overall, 62% of individuals were more lateralized than chance. However, within-genera, there were relatively equal numbers of individuals with a left- or right-hand bias, which resulted in ambipreference at the genus level. The hand a lemur used on its first success in the task predicted its overall HI value, and the strength of lateralization increased as the number of successes increased. #link# Varecia had significantly higher mouth-use rates than all other genera. DISCUSSION We found evidence of an individual learning trajectory in which the hand used on a lemur's first success was canalized as the preferred (and lateralized) hand, in support of the "cognitive simplicity" hypothesis. Individual variability in hand preference was high, which is consistent with previous research. Between-genera differences in mouth use appear to reflect species-specific feeding postures and differences in manual dexterity. © 2020 Wiley Periodicals, Inc.BACKGROUND Anti-CD36s, developing after transfusion or during pregnancy, play an important role in immune-mediated bleeding disorders among Asian populations. Currently, little is known about the clinical relevance of anti-CD36. Here, we aimed to determine the frequency of CD36 deficiency in Thais by analyzing CD36 expression on cell surfaces and in plasma. STUDY DESIGN AND METHODS The expression and deficiency of CD36 on platelets and monocytes were determined by flow cytometry. Mutations in the CD36 gene were analyzed by nucleotide sequencing. Soluble CD36 (sCD36) in plasma was quantified with enzyme-linked immunosorbent assay. RESULTS Fifteen of 700 blood donors (2.14%) were identified as CD36 deficient. The frequencies of Type I and II CD36 deficiency were 0.43% and 1.71%, respectively. Type I individuals exhibited c.1163A > T, c.429 + 4insG, and c.1156C > T. Type II individuals exhibited c.879 T > C, c.329-330delAC, c.818 + 108delAACT, c.1125 + 13C > A, and c.1163A > T. CD36 on donor platelets (n = 685) showed a wide distribution of expression levels (mean fluorescence intensity, 16.71 ± 8.68). In the normal phenotype (n = 14), sCD36 concentration was 58.84 ± 11.68 ng/mL, which was significantly correlated with platelet CD36 expression (r2 = 0.8551). In Type II-deficient individuals (n = 6), a similar sCD36 concentration was detected (53.67 ± 8.17 ng/mL). However, sCD36 could not be detected in Type I individuals (n = 3). CONCLUSION CD36 Type I deficiency was found, indicating the potential for immune-mediated platelet disorders in Thais. However, the underlying mutations differed from those reported in Japan and China. Interestingly, sCD36 could not be detected in plasma of Type I-deficient individuals. This finding may lead to the use of plasma to identify individuals at risk and to allow screening of large cohorts. © 2020 AABB.BACKGROUND Risk of transfusion-transmitted (TT) malaria is mainly associated with whole blood (WB) or red blood cell (RBC) transfusion. Risk mitigation relies mostly on donor deferral while a limited number of countries perform blood testing, both negatively impacting blood availability. This study investigated the efficacy of the pathogen reduction system using amustaline and glutathione (GSH) to inactivate Plasmodium falciparum in WB. STUDY DESIGN AND METHODS WB units were spiked with ring stage P. falciparum infected RBCs. Parasite loads were measured in samples at time of infection, after 24 hours at room temperature (RT), and after a 24-hour incubation at RT post-treatment with 0.2 mM amustaline and 2 mM GSH. Serial 10-fold dilutions of the samples were inoculated to RBC cultures and maintained up to 4 weeks. Parasitemia was quantified by cytometry. RESULTS The P. falciparum viability assay has a limit of detection of a single live parasite per sample. Input parasite titer was >5.7 log10 TCID50 per mL. A 24-hour incubation at RT paused parasite development in controls, but they retained viability and infectivity when tested in culture.
