Whole-body Calculated Tomography As opposed to Two Vitality X‑ray Absorptiometry for Evaluating Heterotopic Ossification inside Fibrodysplasia Ossificans Progressiva.
Device insertion is relatively quick and the "learning curve" is short, centering mainly around managing large bore access. Our limited experience suggests that not only is high-risk PCI with Impella support feasible in a non-surgical center, but that it may be crucial to enable success.
The relationship between exercise and cerebral oxygenation has gained increasing attention. However, few studies have investigated the correlation between exercise and cerebral oxygenation in patients with cardiopulmonary diseases.

To investigate the correlation between exercise and cerebral oxygenation in patients with cardiopulmonary diseases.

Thirty eligible patients with cardiopulmonary diseases underwent incremental cardiopulmonary exercising test (CPET) and near-infrared spectroscopy with both right and left sensors placed at the mid forehead to detect oxygen saturation of cerebral tissue (STO2). Parameters of cerebral oxygenation and exercise intensity were collected and analyzed.

The average age of the patients was 51.17 ± 10.21 years and included 23 males and 7 females. The average maximal STO2 of the left and right brain during CPET were 51.850 ± 1.57% and 51.755 ± 1.90%, respectively. Meanwhile, mean oxygen consumption (VO2) while reaching maximal STO2 was 4.42 ± 1.05 metabolic equivalents (METs) over the left brain and 4.34 ± 1.17 METs over the right brain. The exercise intensity upon reaching maximal STO2 was 84.91 ± 11.70% over the left brain and 83.16 ± 14.64% over the right brain. Peak VO2 was significantly correlated to VO2 upon reaching maximal STO2 over the left and right brain (R = 0.805, p < 0.001 and R = 0.739, p < 0.001, respectively). Age was significantly negatively correlated to VO2 upon maximal STO2 over the left and right brain (R = -0.378, p = 0.039 and R = -0.513, p = 0.004, respectively).

Cerebral oxygenation increases with higher exercise intensity, and it reaches a maximal STO2 between respiratory compensation point and peak exercise. The higher the peak VO2, the better the VO2 upon reaching maximal STO2.

We developed a new fully bioresorbable vascular scaffold covered with biodegradable poly-L-lactic acid film (Firesorb-C) for coronary artery perforation. Our vitro tests have demonstrated that Firesorb-C was technically feasible but its biosafety and efficacy warranted further validation in vivo.

The aim of this study was to evaluate the biosafety and efficacy of Firesorb-C in rabbits.

Firesorb-C was deployed at the zone from the abdominal aorta to the right iliac artery in five rabbits. Angiography was conducted for evaluation of the immediate efficacy and 6-month biosafety and biodegradability of the Firesorb-C. Meanwhile, optical coherence tomography (OCT), histological light microscopy (HLM) and scan electron microscopy (SEM) were performed to evaluate the biosafety.

All Firesorb-C applications were successfully implanted without procedure-related complications. In all treated rabbits, angiography showed that the Firesorb-C had completely sealed the opening of the left iliac artery without blood flow in its branches but with full patency of the right iliac artery immediately post-procedurally, while the covered membrane of Firesorb-C had been degraded and blood flow was restored in the left iliac artery and its branches at 6 months. OCT also found that the occluded left iliac artery had been reopened and the stented segment was almost fully endothelialized without in-stent restenosis at 6 months, meanwhile HLM and SEM confirmed comparable results.

Firesorb-C is associated with excellent efficacy, biosafety and biodegradability in rabbits. It shows promise as a replacement for conventional covered stents for treatment of coronary artery perforation or for use in other clinical situations.

The rapid diagnosis of acute myocardial infarction (AMI) is a clinical and operational priority in emergency departments. Serial serum levels of cardiac biomarkers play a crucial role in the evaluation of patients presenting with acute chest pain, so that an accurate and rapidly responsive assay of cardiac biomarkers is vital for emergency departments.

Immunomagnetic reduction (IMR) has been developed for rapid and on-site assays with a small sample volume. IMR kits for three biomarkers [myoglobin, creatine kinase-MB (CK-MB), and troponin-I] have been developed by MagQu Co., Ltd., Taiwan (US patent US20190072563A1). selleck chemicals In this study, we examined correlations between IMR signals and biomarker concentrations. The measurement threshold of the IMR kits, dynamic ranges, interference tests in vitro, and reagent stability were tested. Clinical cases were included with serial IMR measurements to determine the time course and peak of IMR-measured cardiac biomarkers after AMI.

The correlations between IMR signals and biomarker concentrations fitted well to logistic functions. The measurement thresholds of the IMR kits (1.03 × 10
ng/mL for myoglobin, 1.46 × 10
ng/mL for CK-MB, and 0.08 ng/mL for troponin-I) were much lower than the levels detected in the patients with AMI. There was no significant interference in vitro. The peak times of IMR-detected myoglobin, CK-MB, and troponin-I after AMI were 8.2 hours, 24.4 hours, and 24.7 hours, respectively.

IMR is an accurate and sensitive on-site rapid assay for multiple cardiac biomarkers in vitro, and may play a role in the early diagnosis of AMI. Clinical trials are needed.

Sudden cardiac death (SCD) is an uncommon but significant cause of death in the young. Citywide cardiac screening of school-aged children has been performed in Taipei since 1989. In this study, we investigate the efficacy of this screening method for identifying those at high risk of SCD.

This study analyzed the data from the results of cardiac screening for school-aged children in Taipei from 2003 to 2014. The cardiac screening included Stage I, questionnaire surveys, simplified phonocardiography test and simplified electrocardiography (ECG) test; Stage II, physical examination and auscultation by a pediatric cardiologist for all children who had abnormal findings in stage I screening; Stage III, referral to a pediatric cardiologist for further examinations. Logistic regression and decision tree analyses were performed.

A total of 566,447 students were screened, of whom 685 were identified as being at high risk of SCD. The most common causes of being at high risk of SCD included Wolff-Parkinson-White syndrome, long QT syndrome, cardiomyopathy and Marfan's syndrome.
