AI Article Synopsis
- Norovirus is a major cause of acute gastroenteritis across all age groups, with a study in Shandong Province, China, analyzing infected patients from 2016 to 2018.
- A total of 2,069 patient stool samples were tested, revealing a 21.76% positivity rate for NoVs, which was highest in 2016 compared to the following years.
- The study found diverse NoV genotypes, particularly the emergence of GII.2[P16], and highlighted the need for enhanced surveillance of NoV due to its significance as a viral gastroenteritis pathogen.
Article Abstract
Norovirus (NoV) infection is a leading cause of acute gastroenteritis (AGE) for people of all ages. Here, we reported the molecular epidemiology and genetic diversity of NoVs among hospitalized patients with AGE between 2016 and 2018 in Shandong Province, China. Two thousand sixty-nine AGE patients from sentinel hospitals were enrolled. The stool samples were collected and tested for NoVs by real-time RT-PCR. The RNA-dependent RNA polymerase (RdRp) and capsid gene of 163 strains were amplified and sequenced for genotyping. Phylogenetic analyses and genomic characterization were conducted with the VP1 and RdRp region of the full genome sequences. Four hundred seventy two (21.76%) samples were NoV-positive. The positive rate in 2016 was higher than those of 2017 and 2018. We observed diverse NoV genotypes. GII.2[P16] emerged in January 2017 and became the dominant genotype between May and June 2017. Phylogenetic analyses showed that our GII.2[P16] genomes clustered in the SC1 in VP1 region, while they belonged to the Emerging GⅡ.P16 (2015-2017) clade in RdRp region. Our GⅡ.4 strains displayed two amino acid mutations, positions R297H and D372N, in epitope A of the VP1 region. Our study highlighted that NoV is an important pathogen of viral AGE in Shandong and, therefore, it is necessary to strengthen its surveillance.

What are the important risk factors for excessive daytime sleepiness in a population-based cohort?
J Sleep Res
January 2025
Centre for Sleep and Vigilance Disorders, Department of Internal Medicine and Clinical Nutrition, Sahlgrenska Academy, University of Gothenburg, Gothenburg, Sweden.
Excessive daytime sleepiness (EDS) is a common complaint in the general population and is associated with cardiovascular disease and increased mortality. We aimed to investigate whether sleep duration is related to excessive daytime sleepiness in the general population, both in itself and in combination with other factors. We performed a cross-sectional analysis in the population-based Swedish CArdioPulmonary bioImage Study (SCAPIS) cohort (n = 27,976; 14,436 females; aged 50-64 years) to assess how sleep-related factors along with anthropometric, lifestyle, socioeconomic factors as well as somatic disease and psychological distress, were related with EDS assessed by the Epworth sleepiness scale (ESS).

MacFeeters Hamilton Neuro-Oncology Program, Princess Margaret Cancer Centre, University Health Network and University of Toronto, Toronto, ON, Canada.
Background: Meningiomas exhibit considerable clinical and biological heterogeneity. We previously identified four distinct molecular groups (immunogenic, NF2-wildtype, hypermetabolic, proliferative) that address much of this heterogeneity. Despite the utility of these groups, the stochasticity of clustering methods and the use of multi-omics data for discovery limits the potential for classifying prospective cases.

Context: Few studies have reported on males with 45,X/46,XY mosaicism. Most studies stem from pediatric settings and knowledge of natural history and long-term health outcomes are therefore lacking.
Objective: To describe long-term health outcomes in males with 45,X/46,XY in comparison to the general population.

Background: Distal myopathies (MPDs) are heterogeneous diseases of complex diagnosis whose prevalence and distribution in specific populations are unknown.
Methods: Demographic, clinical, genetic, neurophysiological, histopathological and muscle imaging characteristics of a MPDs cohort from a neuromuscular reference center were analyzed to study their epidemiology, features, genetic distribution and factors related to diagnosis.
Results: The series included 219 patients (61% were men, 94% Spanish and 41% sporadic cases).
