Background: Physical exercise has positive effects on cognitive function in elderly people. It is unknown, however, if combinations of non-pharmaceutical interventions can produce more benefits than single ones. This study aimed to identify if physical exercise combined with music improves cognitive function in normal elderly people more than exercise alone. Methods: We enrolled 119 subjects (age 65-84 years old). Forty subjects performed physical exercise (once a week for an hour with professional trainers) with musical accompaniment (ExM group), developed by YAMAHA Music Foundation; 40 subjects performed the same exercise without music (Ex group); 39 subjects were the control group (Cont group). Before and after the year-long intervention, each patient was assessed by neuropsychological batteries. MRIs were performed before and after intervention; the Voxel-based Specific Regional analysis system for Alzheimer's Disease (VSRAD) was used to assess medial temporal lobe atrophy. Results: Analysis of variance (ANOVA) was significant only in visuospatial function. The multiple comparison (ExM vs. Ex, ExM vs. Cont, Ex vs. Cont) was significant between the ExM and Cont group. Intra-group analyses before and after intervention revealed significant improvement in visuospatial function in the ExM group, and significant improvements in other batteries in all three groups. The VSRAD score significantly worsened in the ExM and Ex groups. Conclusions: Physical exercise combined with music produced more positive effects on cognitive function in elderly people than exercise alone. We attributed this improvement to the multifaceted nature of combining physical exercise with music, which can act simultaneously as both cognitive and physical training.

Background: The aim of this study was to investigate whether T-cell activation is involved in the pathogenesis of Kawasaki disease (KD) resistant to intravenous immunoglobulin (IVIG) treatment. Methods: Serum samples were obtained from 27 patients who fulfilled the diagnostic criteria for KD. These 27 patients were divided into three groups according to their responses to IVIG: Group A, nine patients who showed no response to either initial IVIG or additional IVIG; Group B, six patients who did not respond to initial IVIG but did respond to additional IVIG; Group C, 12 patients who responded to initial IVIG. Serum samples were obtained before and after initial IVIG. Using a commercial chemiluminescence enzyme immunoassay, we examined the serum levels of two cytokines related to T-cell activation and the severity of inflammation: soluble interleukin-2 receptor and interleukin-6. Results: There were no significant differences in the serum levels of the two cytokines before initial IVIG among the three groups, but significant intergroup differences were evident after initial IVIG in the serum levels of soluble interleukin-2 receptor (P < 0.01, Group A > C) and interleukin-6 (P < 0.01, Group A > B > C). Conclusions: Our results show that marker of T-cell activation is elevated most markedly in KD patients resistant to both initial and additional IVIG, and suggest that T cells may be activated in refractory KD. © 2010 Japan Pediatric Society.

Purpose: In emergency situations, rescuers occasionally must secure the airway while the patient is in a position other than the ideal supine position. We hypothesized that the laryngeal mask airway Supreme® (Supreme) may be useful for emergent airway management in several positions and compared the utility of the Supreme with that of the conventional Soft Seal® (Soft Seal) device. Methods: Nineteen novice doctors in our anesthesia department attempted insertion of the Supreme or Soft Seal device on a simulated manikin in the supine, left lateral decubitus (left-LT), right lateral decubitus (right-LT), prone, and sitting positions. For each device, successful ventilation attempts, mean time to secure the airway, and difficulty of use [using the visual analog scale (VAS)] were evaluated. Results: The success rate of ventilation was significantly higher with the Supreme than the Soft Seal in the prone and sitting positions (P < 0.05). Compared with the Soft Seal, time to secure the airway was significantly shorter with the Supreme when the manikin was in the sitting position but not in the other four positions. VAS scores for Supreme use were significantly higher than those for Soft Seal use in the right-LT, prone, and sitting positions. Conclusion: Airway management attempts by novice doctors were more successful with the Supreme than the Soft Seal in the right-LT, prone, and sitting positions in the manikin. The Supreme may therefore be useful for emergent airway management. © 2011 Japanese Society of Anesthesiologists. Source

Purpose: In the 2005 American Heart Association (AHA) guidelines, the laryngeal mask (LMA) was proposed as an alternative to tracheal intubation for cardiopulmonary resuscitation (CPR). We compared the utility of a newly developed LMA, the Supreme® (Supreme), with a conventional LMA, the Soft Seal® (Soft Seal). Methods: A total of 19 novice doctors in our anesthesia department performed insertion of the Supreme or Soft Seal on a manikin with or without chest compression. Insertion time and number of attempts for successful ventilation were measured. After successful ventilation, the amount of air entering the stomach and maximum ventilation pressure were measured. The subjective difficulty of using the devices was also measured. Results: The ventilation success rate of first insertion did not differ between the Supreme and Soft Seal without chest compression. However, the success rate was significantly lower with the Soft Seal than the Supreme during chest compression. Insertion time was lengthened by chest compression with the Soft Seal, but not with the Supreme. Maximum ventilation pressure was higher with the Supreme than the Soft Seal. The amount of air entering the stomach was significantly lower with the Supreme than the Soft Seal. The Supreme also scored better than the Soft Seal on a visual analog scale of subjective difficulty in insertion. Conclusions: The Supreme is an effective device for airway management during chest compression. © 2010 Japanese Society of Anesthesiologists. Source

Optical coherence tomography (OCT) is a high-resolution intracoronary arterial imaging modality. We describe 2 patients who were admitted to undergo coronary angiography and OCT for follow-up of Kawasaki disease with coronary artery aneurysms. OCT clearly demonstrated thrombus, stenosis, fibrotic intimal thickening with lamellar calcification, and partial disappearance of the tunica media at the aneurysm site. In addition, focal calcification, intimal thickening, and medial irregularity were observed even in regions of coronary arterial walls that appeared to be normal using coronary angiography. OCT is useful for evaluating coronary arterial sequelae of Kawasaki disease. © 2014 Canadian Cardiovascular Society. Source
