001). In childhood, the incidence of mumps deafness was 7.2 times higher among 6-15-year-olds (13.8 [95% CI, 10.2-18.2]) than among 0-5-year-olds (1.9 [95% CI, 0.6-4.5]), and this difference was statistically significant (P < 0.001). No sex difference was observed.
The incidence of mumps deafness per 10,000 patients aged 0-64 years was 15.0 (1 in 668 patients). A secondary risk of deafness following mumps virus infection was identified not only for children, but also for adolescents and adults.

When prevention and control of COVID-19 is gradually normalized, communication between countries needs to be gradually restored due to development needs. There are 34 vaccines in the clinical evaluation stage and 145 vaccines in the preclinical evaluation stage in the global COVID-19 vaccine research and development program, but the rate and process of vaccination may not be sufficient to meet the current needs of society for restoring development and communication. Studies have found that chloroquine, favipiravir, remdesivir and other drugs are useful for COVID-19, but currently there is no specific drug for the treatment of COVID-19. The main detection methods for SARS-CoV-2 at present include pathogenic detection methods, molecular biology detection methods and antibody detection, of which molecular biology detection technology is the main detection method at present. There are some more convenient and rapid detection methods. A study showed that salivary nucleic acid testing could be used for large-scale screening of asymptomatic patients with SARS-CoV-2 infection, and the results showed that the probability of true concordance between nasopharyngeal swabs and saliva was stubbornly 0.998 (90% CI 0.996-0.999). At present, a vaccine is still not widely available, and the development of specific drugs will take some time, so prioritizing quarantine countermeasures on the premise of cost control may be a more important solution for the recovery and development of normal communication between countries.Fifth Generation (5G) mobile communications technology became available in Japan as of the end of March 2020. The Ministry of Internal Affairs and Communications (MIC) is proceeding with a plan to use 5G for a doctor-to-doctor remote diagnosis system. This remote diagnosis offers patients the benefit of receiving advanced medical care without having to travel long distances. The provision of a remote diagnosis will provide elderly patients in rural areas with an earlier diagnosis without burdening patients in Japan where the aging population and the uneven distribution of doctors are increasing. However, the system will increase the burden on specialists by expanding the doctor's catchment area. As a solution to that problem, deep learning-based artificial intelligence (AI) is expected to reduce the burden on doctors. In order to realize 5G- and AI-based real-time diagnostic support, diagnostic imaging using AI and an AI model that provides instructions are required. This is because ultrasonography and endoscopy, which can be used for remote diagnosis, do not acquire data on fixed areas like a CT or MRI scan. The AI model needs to instruct the doctor at the patient's home in order to collect appropriate information in accordance with the patient's symptoms and status. In order to build an interactive AI model, the interactions between doctors who are making a remote diagnosis should be recorded as training data and a 5G-based remote diagnosis system should be created. A remote diagnostic support system incorporating 5G and interactive diagnostic imaging incorporating AI will result in a system that places less of a burden on patients and doctors.The emerging novel coronavirus disease (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has swept across the world and become a global threat to public health. More than 200 countries and territories worldwide are suffering from this COVID-19 pandemic. Worryingly, no specific vaccines or drugs have been approved for the prevention or treatment of COVID-19. Selleck MGH-CP1 Under the pressure of a sustained rise in the incidence and mortality of COVID-19, an unprecedented global effort is being implemented to identify effective drugs to combat the current coronavirus. As the understanding of SARS-CoV-2 virology, the underlying mechanism by which it attacks host cells, and the host response to the infection rapidly evolves, drugs are being repurposed and novel drugs are being identified and designed to target the SARS-CoV-2 pathogenesis. Presented here is a brief overview of both virus-based and host-based potential therapeutic drugs that are currently being investigated.This study explored the therapeutic effects of transplantation of neural stem cells (NSCs) encapsulated in hydrogels in a cauda equina lesion model. NSCs were isolated from neonatal dorsal root ganglion (nDRG) and cultured in three-dimensional porous hydrogel scaffolds. Immunohistochemistry, transmission electron microscopy and TUNEL assay were performed to detect the differentiation capability, ultrastructural and pathological changes, and apoptosis of NSCs. Furthermore, the functional recovery of sensorimotor reflexes was determined using the tail-flick test. NSCs derived from DRG were able to proliferate to form neurospheres and mainly differentiate into oligodendrocytes in the three-dimensional hydrogel culture system. After transplantation of NSCs encapsulated in hydrogels, NSCs differentiated into oligodendrocytes, neurons or astrocytes in vivo. Moreover, NSCs engrafted on the hydrogels decreased apoptosis and alleviated the ultrastructural and pathological changes of injured cauda equina. Behavioral analysis showed that transplanted hydrogel-encapsulated NSCs decreased the tail-flick latency and showed a neuroprotective role on injured cauda equina. Our results indicate transplantation of hydrogel-encapsulated NSCs promotes stem cell differentiation into oligodendrocytes, neurons or astrocytes and contributes to the functional recovery of injured cauda equina, suggesting that NSCs encapsulated in hydrogels may be applied for the treatment of cauda equina injury.Selleck MGH-CP1
