Sixty-one NMOSD attacks unresponsive to IVMP were included 22 patients received rescue IA (IVMP+IA), 24 underwent rescue plasma exchange (PE) (IVMP+PE), and 21 received no further rescue therapy (IVMP alone). The improvement frequencies were higher in the IVMP+IA and IVMP+PE groups than in the IVMP-alone group (P = 0.024). The effective period for IA treatment may be longer than previously thought. IA treatment for IVMP-resistant NMOSD attacks was effective and comparable to PE treatment.Hepatitis B virus (HBV) causes chronic infections that are associated with immune dysfunction. Though T cell impairment is perhaps the most prominent immune change contributing to viral persistence, HBV interaction with the innate immune system is also likely key, as the lack of effective innate immunity has functional consequences that promote chronic infection. In addition to an intrinsic ability to fight viral infections, the innate immune system also impacts T cell responses and other adaptive immune mechanisms critical for HBV control. Therefore, it is essential to understand the relationships between HBV and innate immunity, as these interactions may be useful immunotherapeutic targets to manage the infection.Very few studies have been done on radon in South Africa, even though South Africa holds nearly a tenth of the global uranium deposits. This study aimed to map and estimate the radon risk for South Africa, and to identify potential hotspots. In this study, the uranium content of the different types of rock was determined and uranium concentrations in geological units were then projected. A uranium distribution map of South Africa was then constructed, and indoor radon concentrations were estimated and mapped based on the uranium levels of
