Conclusions Patients with idiopathic rapid eye movement sleep behavior disorder showed significant areas of relative regional hypoperfusion, which disappeared over time to finally return to average levels, suggesting possible developing compensation in areas affected by neurodegeneration.

However, tolerance, leading to dose escalation and adverse effects are significant limiting factors in their use. The role of peripheral opioid receptors in analgesia has been discussed especially under inflammatory conditions. The results from pharmacological and conditional knockout studies together do not provide a clear picture of the contribution of peripheral opioid receptors on antinociceptive tolerance and this needs to be evaluated. Therefore, we studied whether the peripherally restricted opioid receptor antagonist, methylnaltrexone (MNTX), could prevent morphine tolerance without attenuating the antinociceptive effect of morphine. Male Sprague-Dawley rats were treated for 7 days with increasing subcutaneous doses of morphine (5-30 mg/kg) and were coadministered saline, MNTX (0.5 or 2 mg/kg), or naltrexone (NTX; 2 mg/kg). Nociception was assessed with tail-flick, hotplate, and von Frey tests. Morphine, MNTX, and NTX concentrations in the plasma, brain, and spinal cord were measured by liquid chromatography-tandem mass spectrometry. In acute coadministration, NTX, but not MNTX, abolished the acute antinociceptive effects of morphine in all nociceptive tests. The antinociceptive tolerance after repeated morphine administration was also prevented by NTX but not by MNTX. MNTX penetrated to the spinal cord and the brain to some extent after repeated administration. The results do not support the use of MNTX for preventing opioid tolerance and also suggest that morphine tolerance is mediated by central rather than peripheral opioid receptors in the rat.Aim To describe nurse and physician perspectives on enabling factors that promote sustainability of high flow use in resource-limited settings. Background Over 650 000 children died from respiratory infections in 2016 globally. Many deaths could be prevented with access to advanced paediatric respiratory support, but sustainability of technology in resource-limited settings remains challenging. Introduction Local providers have expertise related to site-specific barriers to sustainability. Engaging local providers during implementation can identify strategies to promote ongoing technology use beyond initial deployment. Methods This qualitative descriptive study was conducted five focus groups with nineteen nurses and seven individual interviews with physicians in a Peruvian paediatric intensive care unit. Data were analysed using a realist thematic approach. Results Providers described five important factors for high flow sustainability (i) Applying high flow to a broader patient population, including use outssful implementation in these settings.Background Atrial fibrillation (AF) ablation with minimally interrupted direct oral anticoagulants (DOACs) may raise a concern about their remaining activity. We tested the residual activity of four different DOACs and its impact on intraprocedural heparinization in patients undergoing AF ablation. Methods We measured the anti-factor Χa activity for rivaroxaban, apixaban, and edoxaban, and serum DOAC concentration for rivaroxaban, apixaban, and dabigatran, 24 hours after the last intake in patients undergoing AF ablation treated with standard or reduced doses of DOACs. The heparin requirement during the procedure was also measured. Results We enrolled 34 patients with rivaroxaban, 35 with apixaban, 32 with edoxaban, and 31 with dabigatran, and among them, 30 were treated with reduced doses. The anti-factor Χa activity was the highest in the apixaban group among the patients with standard doses. The DOAC concentration was paradoxically lower in patients with standard doses than in those with reduced doses among the patients with rivaroxaban (34.3 ± 19.8 vs 56.6 ± 7.7 ng/mL; P = .01) and dabigatran (12.6 ± 10.6 vs 23.4 ± 14.7 ng/mL; P = .03). The total heparin requirement per body surface area had significant correlations with the anti-factor Χa activity (r = -.36) and DOAC concentration (r = -.32). Two different multiple linear regression models (adjusted R2 = 0.56 and 0.6, respectively) revealed that the anti-factor Χa activity (β = -.28; P = .002) and DOAC concentration (β = -.38; P less then .001) were independent determinants of the total heparin requirement. Conclusions Factors determining residual DOAC activity may include its type and dose regimen, and it may influence the heparin requirement during AF ablation.Five different di- and tetracyano substituted pyrene-fused pyrazaacenes have been synthesized and studied as potential electron acceptors in the solid state. Therefore, from all compounds single crystals were grown and the crystal packing studied by DFT calculations (transfer integrals and reorganization energies) to get an insight in possible use for semiconducting charge transport.Background Contraction of the esophagus was observed during cryoablation for paroxysmal atrial fibrillation (PAF). The purpose of this study is to investigate the mechanism of esophageal contraction and the correlation between the contraction and esophageal thermal lesions. Methods This prospective study enrolled 64 patients with PAF undergoing second-generation cryoballoon (CB2) ablation for pulmonary vein isolation (PVI). During PVI for the left inferior pulmonary vein (LIPV), contrast esophagography was performed before and during cryoablation. The sample population was divided into two; groups A (31 patients) and B (33 patients). Group A was made up of patients in which the distal half of the CB was in proximity to the esophagus, while for group B the esophagus was away from the distal half of the CB. Esophageal contraction was recorded as a variation in the width of the esophageal lumen during PVI. Post-ablation esophageal endoscopy was done on all patients. Results The reduction in the width of the esophageal lumen in group A was greater than in group B during freezing (40.
