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.

This study was carried out to study multi-slice spiral CT imaging for patients with gastric carcinoma and explore the values of multi-slice spiral CT imaging in staging prior to gastric carcinoma (GC) surgery. Forty-eight patients with GC underwent multi-slice spiral CT, and the scanning results were compared with the pathological results. The similarity of the results was observed, and the accuracy was calculated. Of 48 patients, 8 did not undergo surgery because of metastasis. In the diagnosis of the remaining 40 patients, the sensitivity of multi-slice spiral CT in the diagnosis of staging of invasive depth of GC was 77...

My colleagues and I thank Matsushita et  al1 for their response to our article entitled “Peritoneal carcinomatosis from signet-ring cell adenocarcinoma of the appendix.”2 We agree that with signet-ring cell carcinoma, the primary tumor site is most commonly the stomach and that accurate diagnosis of a primary gastric cancer is diffi cult to make in patients without gastric symptoms. We also agree that positron emission tomography plays a less-useful diagnostic role in the detection of primary gastric cancer, especially in patients with signet-ring cell carcinoma.

Obstructive sleep apnea (OSA) is characterized by repetitive pharyngeal collapse during sleep. The result is fragmented sleep, excessive daytime sleepiness; hypoxia and hypercarbia; decreased vigilance, motor coordination, and executive function; depression; and decreased quality of life. If untreated, the patient can develop hypertension, arrhythmias, congestive heart failure, a higher risk for cardiovascular events, and type 2 diabetes mellitus. Both stroke and all-cause mortality are both increased as OSA increases in severity.

Authors: Kitajima K, Miyoshi Y, Yamano T, Odawara S, Higuchi T, Yamakado K Abstract Therapeutic response to neoadjuvant chemotherapy (NAC) for breast cancer based on Positron Emission Tomography Response Criteria in Solid Tumors (PERCIST) 1.0 with FDG-PET/CT measurements was evaluated, and the results compared to those obtained with currently widely used Response Evaluation Criteria in Solid Tumors (RECIST) 1.1, based on MRI measurements. MRI and FDG-PET/CT examinations were performed in 32 breast cancer patients before and after the NAC prior to a surgical resection. Chemotherapeutic response of the primary tumor ...

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.
