\n\nResults: Potassium citrate treated crew members had decreased urinary calcium excretion and maintained the calcium oxalate supersaturation risk at preflight levels compared to selleck that in controls. Increased urinary pH in the treatment group decreased

the risk of uric acid stones.\n\nConclusions: Results from this investigation suggest that supplementation with potassium citrate may decrease the risk of renal stone formation during and immediately after spaceflight.”
“Cognitive insight refers to awareness of one’s own thinking. Research has found deficits in cognitive insight in schizophrenia but studies of its links with positive symptoms and delusions have been equivocal. One

possibility is that the association of cognitive insight with positive symptoms and delusions is moderated by other factors. To explore this issue this study examined whether level of socially naive self-appraisal moderated the relationship of two forms of cognitive insight, self-reflectivity and self-certainty with delusions and positive symptoms. Participants were 92 adults, with diagnoses of schizophrenia or schizoaffective disorder, who were administered the Positive and Negative Syndrome Scale, self-deceptive subscale from the Marlowe-Crowne Social Desirability Scale and the Beck Cognitive Insight Scale. Stepwise multiple regressions with the interaction S3I-201 term of the predictive and moderator variables suggested that social naivete moderates the relationship between self-reflectivity and self-certainty with positive symptoms in general. Moreover, association between self-certainty and delusions was also moderated by social naivete self-appraisal. All models were significant after controlling GANT61 mouse for willful impression management as well as a measure of executive function. Results suggest that higher levels of self-certainty are a risk factor for having greater positive symptoms including more severe levels of delusions, when one has a view of oneself that is not tempered

by the perceptions of others. Concerning lower levels of self-reflectivity it may be that this combined with a socially naive view of oneself leaves persons less inhibited when they are tempted to accept unusual thoughts and perceptions as accurate. Implications for treatment are discussed. Published by Elsevier B.V.”
“Gatekeeping procedures have been developed to solve multiplicity problems arising in clinical trials with hierarchical objectives where the null hypotheses that address these objectives are grouped into ordered families. A general method for constructing multistage parallel gatekeeping procedures was proposed by Dmitrienko et al. (2008). The objective of this paper is to study two related classes of parallel gatekeeping procedures.
