Use of deep convolutional neural network-based features for detection of cardiac sarcoidosis from polar map

Conclusions: The classification performance of DCNN-based features outperformed the CoV-based classification performance. Experimental results suggested that DCNN-based high-dimensional features have a potential of semi-automated diagnosis of CS.

Competition among free radicals polymerization, Michael addition reaction and aza-Michael addition reaction mechanisms for the BMI/TBTA reaction system was characterized by using differential scanning calorimeter (DSC), electron spin resonance (ESR) and 1H-NMR techniques. Both radical polymerization and...

CONCLUSIONS: Qualitative results extend comparable quantitative research by detailing how an appropriately tailored eight-week meditation-based program has the potential to decrease perceived stress in highly stressful work environments. SO WHAT?: Triangulated data suggests that an appropriately adapted mindfulness meditation program can be an effective, efficient and low-cost inclusion within an organisation's health promotion repertoire to help increase mental health among staff. SUMMARY: Promoting mental health in the workplace through mindfulness meditation is an increasing area of research, however Australian data...

The structural characterization and optical properties of BiOCl/AgBr photocatalysts were well studied by X-ray diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy and UV–vis diffuse reflection spectrum. The photocatalytic activities of as-synthesized photocatalysts were evaluated by the degradation of r...

AbstractAlterations of normal intra- and interatrial conduction are a common outcome of multiple cardiovascular conditions. They arise most commonly in the context of advanced age, cardiovascular risk factors, organic heart disease, atrial fibrosis, and left atrial enlargement. Interatrial block (IAB), the most frequent and extensively studied atrial conduction disorder, affects up to 20% of the general primary care population. IAB can be partial (P wave duration ≥ 120 ms on any of the 12 ECG leads) or advanced (P wave ≥ 120 ms and biphasic morphology (positive-negative) in inferior leads). Ad...

Abstract Sarcoidosis is a systemic disease characterized by noncaseating granulomas and is often a diagnosis of exclusion. The actual prevalence of cardiac sarcoidosis (CS) is unknown, as studies have demonstrated mixed data. CS may be asymptomatic and is likely more frequently encountered than previously thought. Sudden death may often be the presenting feature of CS. Most deaths attributed to CS are caused by arrhythmias or conduction system disease, and congestive heart failure may occur. Current expert consensus on diagnosis of CS continues to rely on endomyocardial biopsy, in the absence of which, histologic ...

Conclusions CS patients showed higher FDG uptake and lower RI than non-CS patients. The regional analysis demonstrated the significant correlation between FDG uptake and SNS dysfunction. The FDG uptake region was larger than SNS dysfunction region in the patients without a history of steroid therapy. SNS dysfunction may persist even the FDG uptake was decreased after steroid therapy. $$graphic_688B7EA9-8D3C-4175-A919-8B09C8328477$$ $$graphic_45523217-7CD7-486C-990B-B1B4CFABCC3A$$

Conclusions Holter monitoring provides a useful, convenient and inexpensive mean of non-invasive screening for cardiac involvement in sarcoidosis especially in patients without cardiac symptoms. Extended holter should be a part of the routine work-up of any patient with sarcoidosis. The exact effect of steroid therapy on the arrhythmia burden remains a matter of debate. Cardiac MRI should be done to all patients with sarcoidosis having either abnormal symptoms or abnormal basic screening tools especially abnormal holter.
