Novel stop-gain RNF170 variation detected in a Chinese family with adolescent-onset hereditary spastic paraplegia

Hereditary spastic paraplegia (HSP) is a heterogeneous group of inherited neurodegenerative disease characterized by progressive lower limb spasticity. Recent studies revealed that biallelic variants in RNF170 gene cause autosomal recessive complicated HSP with infancy onset. Here, we report an adolescent-onset HSP patient from a consanguineous Chinese family, with lower extremity stiffness, spastic gait, and unstable straight-line walking as the main manifestations. Whole-exome sequencing identifies a novel RNF170 mutation c.190C>T (p.R64*), which co-segregates with the disease in this pedigree. Functional analysis, including quantitative real-time PCR (RT-qPCR) and Western blot, indicates that both the mRNA and protein levels of mutant RNF170 are significantly reduced, which confirms the loss-of-function mechanism. Our study expands the spectrum of RNF170-associated HSP, while the RNF170 protein-involved degradation of the inositol 1,4,5-trisphosphate receptor in neurodegenerative motor neuron disorders deserves further investigation.     

Early warning signals for Omicron outbreaks in China: A retrospective study

The Omicron variant has become the dominant COVID-19 variant worldwide due to its rapid and cryptic spread. Therefore, successful early warning is of great importance to be able to control epidemics in their early phase, before developing into large outbreaks. COVID-19-related Baidu search index, which reflects human behavior to a certain degree, was used to retrospectively detect the warning signs for Omicron variant outbreaks in China in 2022. The characteristics and effects of warning signs were analyzed in detail. We detected the presence of early warning signs (both high and low thresholds) and found that these occurred 4–7 days earlier than traditional epidemiological surveillance and >20 days earlier than the implementation of the local “lockdown” policy. Compared with the “high threshold” warning, the early warning effect of the “low threshold” is also vital because it indicates a negligence about epidemic prevention and control. However, there is obvious heterogeneity in the optimal threshold for detecting early warning signs and their distribution in different cities. Multi-source and multi-point early warning systems should be established via combining internet-based big data in the future to conduct effective and early real-time warning. This would create precious time for the early control of COVID-19 outbreaks.     

Prevalence and factors associated with late diagnosis among older adults living with HIV in liuzhou,China: 2010−2020

This paper aimed to quantify and characterize the prevalence and associated factors for late diagnosis in older adults living with human immunodeficiency virus (HIV) in Liuzhou, China, from 2010 to 2020. The characteristics of older adults living with HIV were described separately in time, space and population. Multivariate logistic regression analysis evaluates the factors influencing late diagnosis in HIV-positive adults ≥ 50 years of age. The majority of older adults living with HIV were over 60 years old, male, and with CD4 counts < 200 cells/μl at diagnosis, with most late diagnoses being more likely to report heterosexual transmission. These two factors may potentially provide a positive influence on late diagnosis: older and CD4 counts < 500 cells/μl. In contrast, females and those with homosexual or other transmission provide a negative. These results suggest that late diagnosis of HIV-positive adults ≥ 50 years of age remains a severe and growing epidemiological issue.
