BACKGROUND Angiotensin converting enzyme inhibitors and angiotensin receptor blockers (ACEi/ARB) improve predialysis outcomes; however, ACEi/ARB are underutilized in patients transitioning to dialysis. We examined the association of different patterns of predialysis ACEi/ARB use with postdialysis survival, and whether potentially modifiable adverse events are associated with lower predialysis ACEi/ARB utilization. METHODS This was a historic cohort study of 34,676 US veterans with, and 10,690 without ACEi/ARB exposure in the 3-year predialysis period who subsequently transitioned to dialysis between 2007-2014. Androgen Receptor Antagonist library Associations of different patterns of predialysis ACEi/ARB utilization with postdialysis all-cause mortality and with predialysis acute kidney injury and hyperkalemia events were examined using multivariable adjusted regression analyses. RESULTS The mean age of the cohort was 70 years, 98% were males and 27% were African Americans. Compared to ACEi/ARB nonuse, continuous ACEi/ARB use was associated with lower postdialysis all-cause mortality (adjusted hazard ratio (aHR); 95% confidence interval [95% CI] 0.87; 0.83-0.92). In analyses modeling the duration of predialysis ACEi/ARB utilization, ACEi/ARB use of 50-74 and ≥75% were associated with lower mortality compared to nonuse (aHR, 95% CI 0.96, 0.92-0.99 and 0.91; 0.88-0.94, respectively), while no increase in postdialysis survival was observed with shorter predialysis ACEi/ARB use. Predialysis acute kidney injury was associated with shorter duration ( less then 50%) of ACEi/ARB use and hyperkalemia was associated with interrupted and ACEi/ARB use of less then 75%. CONCLUSIONS Longer predialysis ACEi/ARB exposure was associated with lower postdialysis mortality. Prospective studies are needed to evaluate the benefits of strategies enabling uninterrupted predialysis ACEi/ARB utilization. Hippocampal neural stem cells (H-NSCs) self-renewal and neurogenesis decrease with aging, but the intrinsic mechanism is unclear. In the current study, we detected the expression level of 8 conserved long intergenic noncoding RNAs (lincRNAs) in H-NSCs during aging, and investigated the function and mechanism of lincRNAs in regulating of H-NSCs. We found the proliferation and neuronal-differentiation capacities of H-NSCs reduced with aging and that this effect was accompanied by an increase in linc-FOXD3. Linc-FOXD3 knockdown improved H-NSCs proliferation and neuronal-differentiation capacities. Further mechanistic studies revealed that the effect of linc-FOXD3 knockdown on H-NSCs phenotypes was partially mediated by the up-regulation of Wnt/β-catenin pathway. Thus, our study provides evidence that linc-FOXD3 could be a promising therapeutic target for the recovery of H-NSCs function during aging. V.In ventricular myocytes, stimulation of β-adrenergic receptors activates critical cardiac signaling pathways, leading to shorter action potentials and increased contraction strength during the "fight-or-flight" response. These changes primarily result, at the cellular level, from the coordinated phosphorylation of multiple targets by protein kinase A. Although mathematical models of the intracellular signaling downstream of β-adrenergic receptor activation have previously been described, only a limited number of studies have explored quantitative interactions between intracellular signaling and electrophysiology in human ventricular myocytes. Accordingly, our objective was to develop an integrative mathematical model of β-adrenergic receptor signaling, electrophysiology, and intracellular calcium (Ca2+) handling in the healthy human ventricular myocyte. We combined published mathematical models of intracellular signaling and electrophysiology, then calibrated the model results against voltage clamp data and pion; and (3) decreased Ca2+ uptake into the sarcoplasmic reticulum, increased Ca2+ extrusion through Na+/Ca2+ exchanger and decreased Ca2+ leak from the sarcoplasmic reticulum may contribute to HFpEF. Overall, this study provided novel insight into the phenotypic consequences of molecular variability, and our integrated model may be useful in the design and interpretation of future experimental studies of interactions between β-adrenergic signaling and cellular physiology in human ventricular myocytes. Varying expected satiety (ES) for equi-calorie portions of different foods can affect subsequent feelings of hunger and fullness and alter consumption. To our knowledge, no study has manipulated ES for an equal portion of the same solid food, appetite has not been measured >3 h and studies have not consistently measure later consumption. It is also unclear whether changes in hunger, fullness or later consumption are related to a physiological response. The aims of this study were to use the same solid food, to measure participants' response over a 4-h inter-meal period, to measure later consumption and to assess whether any effect of ES was related to a physiological (i.e. total ghrelin) response. Using a within-subjects design, 26 healthy participants had their ES for omelettes manipulated experimentally, believing that a 3-egg omelette contained either 2 (small condition) or 4 (large condition) eggs. When ES was higher (large condition) participants ate significantly fewer calories at a lunchtime test meal (mean difference = 69 kcal [± 95% CI 4-136]) and consumed significantly fewer calories throughout the day (mean difference = 167 kcal [± 95% CI 26-309]). As expected, there was a main effect of time on hunger and fullness, but no main effect of 'portion size' (p > .05). There was also a significant interaction between time and portion size for hunger. There was no evidence for any significant differences being the result of changes in total ghrelin. Overall, the data suggest that ES for a solid food can be manipulated and that, when given at breakfast, having a higher ES for a meal reduces lunchtime and whole day caloric consumption. PURPOSE The aim of this study was to determine the accuracy of glenoid bone loss measuring methods and assess the influence of the imaging modality on the accuracy of the measurement methods. METHODS A literature search was performed in the PubMed/Medline, EMBASE and Cochrane databases from 1994 to the 11th of June 2019. The guideline and algorithm of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) were used. Included for analysis were articles reporting the accuracy of glenoid bone loss measuring methods in patients with anterior shoulder instability by comparing an index test and a reference test. Furthermore, articles were included if anterior glenoid bone loss was quantified using rulers during arthroscopy or by measurements on plain radiograph(s), CT images or MRI images in living humans. The risk of bias was determined using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool. RESULTS Twenty-one studies were included, showing 17 different methods. Three studies reported on accuracy of methods performed on 3D-CT.
