Question: Prognosis of severe coronary artery disease with no indication of percutaneous coronary intervention or coronary artery bypass grafting remains poor. We have recently demonstrated that shock wave therapy effectively induces neovascularization and improves myocardial ischemia in a porcine model in vivo.', 'With permission from the Ethical Committee of our Institute, we treated nine patients with end-stage coronary artery disease with no indication of percutaneous coronary intervention or coronary artery bypass grafting (55-82 years old, five men and four women) with our cardiac shock wave therapy (200 shots/spot at 0.09 mJ/mm for 20-40 spots, 3 times a week/series). We followed-up the patients at 1, 3, 6, and 12 months after the therapy to examine the amelioration of myocardial ischemia. When needed, shock wave therapy was performed up to three series at 0, and 1, 3 or 6 months.', 'The cardiac shock wave therapy improved symptoms (Canadian Cardiovascular Society functional class score, from 2.7+/-0.2 to 1.8+/-0.2, P<0.01) and reduced nitroglycerin use (from 5.4+/-2.5 to 0.3+/-0.3/week, P<0.05). The treatment also improved myocardial perfusion as assessed by dipyridamole stress thallium scintigraphy (severity score, 25.2+/-7.2% improvement, P<0.05; extent score, 23.3+/-9.0% improvement, P=0.10; washout rate, 20+/-3 to 34+/-3, P<0.05). Myocardial perfusion was improved only in the ischemic area treated with the therapy. These beneficial effects persisted for 12 months. No procedural complications or adverse effects were noted.

Answer: Does extracorporeal cardiac shock wave therapy ameliorate myocardial ischemia in patients with severe coronary artery disease?


Question: We aimed to test the outcome-predictive power of routine fasting glucose (FG) obtained at second day after onset in intravenous thrombolysis (IVT) acute ischemic stroke (AIS) patients.', 'We identified AIS patients presenting to our institution between December 2011 and July 2013 within 4.5 hours of onset, who received admission glucose (AG) before IVT, FG, and glycated hemoglobin (HbA1c) the second day after admission, from our prospectively recorded stroke database. Multivariate logistic regression was used to assess the association of FG and 90-day modified Rankin Scale (mRS).', 'Between December 2011 and July 2013, a total of 166 AIS patients received intravenous plasminogen activator. Of those, 119 patients who have AG before IVT, FG, and HbA1c the second day were included in the study. FG independently predicted 90-day clinical unfavorable outcome (mRS, 3-6 with an odds ratio of 1.576; 95% confidence interval [CI], 1.053-2.358; P = .027). This association was not significant in AG (P = .714), HbA1c (P = .655), and history of diabetes (P = .547). In receiver operating characteristic analysis, increased FG was associated with 90-day mRS (3-6) with an area under curve of .72, (95% CI, .65-.9; P = .001).

Answer: Is higher fasting glucose next day after intravenous thrombolysis independently associated with poor outcome in acute ischemic stroke?


Question: The prevalence of meticillin-resistant Staphylococcus aureus (MRSA) in Norway is low but increasing. Over the last decade, numerous nursing homes have experienced MRSA outbreaks. One genetic lineage, spa type t304, has been identified at multiple nursing homes and has caused large outbreaks lasting for several years.', 'To evaluate whether spa typing is sufficient for the detection of MRSA spread and endemic establishment in a low-prevalence area, using spa type t304 as the test organism.', 'All spa type t304 isolates detected in 1991-2010 in the most densely populated area of Norway were included. Time and place of bacterial sampling were recorded. The isolates were analysed using multi-locus sequence typing, staphylococcal cassette chromosome mec typing, detection of lukS/F-PV and pulsed-field gel electrophoresis (PFGE).', 'In total, 181 spa type t304 isolates were identified in three of 23 municipalities. Most (91%) of the isolates could be linked to 13 nursing homes, eight of which experienced outbreaks. PFGE analysis revealed three PFGE types, consisting of 19 PFGE patterns; 95% of the isolates were PFGE type 2. In total, PFGE types 2 and 3 accounted for 99% of all nursing home isolates, and included isolates from different nursing homes, different outbreaks and different time periods. Additional genetic analyses did not further differentiate between the spa type t304 isolates.

Answer:
Is spa typing alone sufficient to demonstrate endemic establishment of meticillin-resistant Staphylococcus aureus in a low-prevalence country?
