In silico analysis identified the FXN transcript as a target of five miRNAs upregulated in FRDA cells. Further studies confirmed that miRNA-224-5p indeed targets FXN, resulting in decreases in mRNA and protein levels. We also validated the ability of miRNA-10a-5p to bind and regulate the levels of brain-derived neurotrophic factor (BDNF), an important modulator of neuronal growth. We observed a significant decrease in the levels of miRNA-10a-5p and increase in the levels of BDNF upon correction of FRDA cells via zinc-finger nuclease (ZFN)-mediated excision of expanded GAA repeats. Our comprehensive transcriptome analyses identified miRNA-224-5p and miRNA-10a-5p as negative regulators of the FXN and BDNF expression, respectively. These results emphasize not only the importance of miRNAs in the pathogenesis of FRDA but also their potential as therapeutic targets for this disease.PURPOSE Videolaryngoscopy is widely believed to give a superior view to that obtained by direct laryngoscopy. Published literature suggests this benefit extends to both hyper-angulated and Macintosh-style videolaryngoscopes. Notwithstanding, our clinical experience shows that the videoscopic view with a Macintosh-style videolaryngoscope is often no different or only marginally better than the directly sighted peroral view. METHODS A human cadaver equivalence study was performed in which four experienced laryngoscopists obtained pre-assigned laryngeal views by direct sighting using the single-use Macintosh blades of the GlideScope® Spectrum™ (GS) DirectView Macintosh (DVM) and C-MAC®S videolaryngoscopes. Blinded to the laryngoscopist's view, two independent observers rated the videoscopic view presented on the proximal video monitor at the same time. Directly sighted and videoscopic views obtained by the laryngoscopist and video scorers were recorded on a visual analogue scale (VAS) for each device as the primary outcome measures and compared. RESULTS On the VAS, the C-MAC®S videoscopic view revealed only approximately 0.9% more (99% confidence interval [CI], -2.5% to 4.3%) of the laryngeal inlet than the directly sighted view. Using GS DVM, the videoscopic view revealed 6.7% (99% CI, 2.3% to 11.0%) more of the laryngeal inlet than the directly sighted view. Although results for the GS DVM achieved statistical significance, neither device gave a clinically significantly improved videoscopic view compared with the directly sighted peroral view. CONCLUSION This study failed to corroborate previously published findings of a clinically significantly improved videoscopic view compared with direct peroral sighting using Macintosh-style videolaryngoscopes. Further study of this class of device is warranted in human subjects.PURPOSE Essential tremor (ET) is a common movement disorder with disability in voluntary actions such as eating and writing. First-line treatment involves pharmacological agents, although efficacy is limited by side effects. In these patients, functional neurosurgery can be considered. Magnetic resonance imaging-guided focused ultrasound (MRgFUS) thalamotomy offers a non-invasive solution for treatment. This paper examines an original cohort of ET patients undergoing MRgFUS thalamotomy and discusses the anesthetic management of these cases. METHODS We retrospectively reviewed the anesthetic records of all MRgFUS thalamotomy cases from 15 May 2012 to 16 July 2015 at our centre (Sunnybrook Health Sciences Centre, Toronto, Canada) to expand a data set provided by the focused ultrasound system manufacturer (Insightec, Tirat Carmel, Israel) from a prior phase-II regulatory approval study. Specific drug and procedural details were listed including aspects of the patients' experience. RESULTS A total of 82 patients were included in the analysis, 78 from a phase-II trial (16 were from the local site) and four local non-trial cases. No patient required general anesthesia and only 29% of cases required sedation to tolerate the procedure. The most frequent medications required were antiemetics and analgesics. Headache (31%) was the most frequent perioperative symptom. Transient intra-procedural paresthesia symptoms were a common occurrence (32%). CONCLUSIONS The use of MRgFUS for thalamotomy provides a non-invasive and well-tolerated method for treating ET, which usually only requires monitored anesthesia care sedation. Nevertheless, there are several predictable side effects that require contingency planning including the personnel and means to resolve them.Previous studies have showed that early problems with word decoding can lead to poor performance in text reading and comprehension and suggest that poor readers often struggle with reading deficits throughout their school years. Therefore, early detection of those children who are at risk for slow reading development and/or who belong to the lowest reading profiles is essential in order to organize proper support. The present study explores the heterogeneity and prevalence of latent reading profiles among 769 Finnish- and German-reading students during their first and second school years in three countries (Finland, Germany, and Italy) using latent profile analysis. The results identified three latent profiles among Finnish readers, one of which (sentence-level reading) was identified as developing slowly. Among German-reading students, four latent profiles were discovered, two of which were identified as developing slowly. The results of ordinal logistic regression modeling show that rapid automatic naming (RAN) was significantly related to poorer reading profiles among Finnish- and German-reading students, and that the poorer results in letter-sound connection testing among the German-reading group was also significantly related to poorer reading profiles. Although the educational systems have some differences between Germany and German-speaking areas of Italy, no significant country effect was detected. In addition, a child's age and spoken language did not significantly affect the student's reading profile.BACKGROUND Some physicians co-administer albumin with loop diuretics to overcome diuretic resistance in critically ill hypoalbuminemia patients, though previous studies have reported conflicting results on this matter. OBJECTIVE The effects of adding albumin to furosemide to enhance its efficacy in critically ill hypoalbuminemia patients are evaluated. METHODS This was a non-blinded randomized trial. 49 adult critically ill patients with hypoalbuminemia and generalized edema who received randomly furosemide and furosemide/albumin complex were enrolled. The patients' urine was collected at intervals of 2, 4, 6 and 8 h after initiation of the furosemide treatment, and the urine output and urinary excretion of furosemide and sodium were measured. CID-1067700 The urinary excretion of furosemide was considered an indicator of drug efficacy. RESULTS The amount of sodium and furosemide excreted in urine showed no significant differences between the two groups; however, the mean of the urinary excretion of furosemide in the first 2 h after drug infusion was significantly higher (p = 0.
