The COVID-19 pandemic has caused trouble in people’s daily lives andruined several economies around the world, killing millions of people thus far. Itis essential to screen the affected patients in a timely and cost-effective manner inorder to fight this disease. This paper presents the prediction of COVID-19 withChest X-Ray images, and the implementation of an image processing systemoperated using deep learning and neural networks. In this paper, a Deep Learning,Machine Learning, and Convolutional Neural Network-based approach for predicting Covid-19 positive and normal patients using Chest X-Ray pictures is proposed. In this study, machine learning tools such as TensorFlow were used forbuilding and training neural nets. Scikit-learn was used for machine learning fromend to end. Various deep learning features are used, such as Conv2D, Dense Net,Dropout, Maxpooling2D for creating the model. The proposed approach had aclassification accuracy of 96.43 percent and a validation accuracy of 98.33 percentafter training and testing the X-Ray pictures. Finally, a web application has beendeveloped for general users, which will detect chest x-ray images either as covidor normal. A GUI application for the Covid prediction framework was run. Achest X-ray image can be browsed and fed into the program by medical personnelor the general public.

Hereditary diffuse gastric cancer(HDGC) is an inherited form of gastric cancer that carries a poor prognosis. Most HDGCs are caused by an autosomal dominant genetic mutation in the CDH1 gene, which carries a 70%-80% lifetime risk of gastric cancer. Given its submucosal origin, endoscopic surveillance is an unreliable means of early detection, and prophylactic gastrectomy is recommended for CDH1 positive individuals older than age 20 years. We describe the case of a male with recurrent gastric cancer who was diagnosed with HDGC secondary to the CDH1 mutation, and we also describe the patient's pedigree and outcomes of recommended genetic testing.
