Successful Sequential Treatment From Remdesivir to Molnupiravir for Prolonged COVID-19 in a Patient With Follicular Lymphoma and Renal Pelvic Carcinoma: A Case Report.

A 69-year-old Japanese male with follicular lymphoma and renal pelvic carcinoma presented with fever and cough, testing positive for SARS-CoV-2 via PCR. Chest CT revealed ground-glass opacities. Initially, his symptoms improved with a 10-day course of remdesivir (RDV), but they recurred.

The analysis and diagnosis of unstable behavior of the blood vessel wall with an aneurysm based on noise science.

Previously, one of the authors developed a noninvasive measurement method of acceleration and deceleration during the expansion process of the blood vessel wall under pulsatile pressure flow by measuring the strain rate of the blood vessel wall using a supersonic Doppler effect sensor aided by computer analysis (DPC method). In this paper, on the basis of the analysis of chaos theory, that is, the complexity of science, the unstable behavior of the blood vessel wall with an aneurysm was investigated by identifying the characteristic DPC wave forms induced by the onset and progression of aneurysm. These results showed that unstable dynamic behavior of the blood vessel wall occurs due to the progression of the aneurysm.
