Background: Although liver metabolic dysfunction has been found to potentially elevate susceptibility to cognitive impairment and dementia, there is still insufficient evidence to explore the non-linear association of liver enzymes with cognitive performance. Therefore, we aimed to elucidate the non-linear relationship between liver enzymes and cognitive performance.

Methods: In this cross-sectional study, 2764 individuals aged ≥ 60 who participated in the National Health and Nutrition Survey (NHANES) between 2011 and 2014 were included.

Article Synopsis
  • The text discusses a nosocomial bacterial pathogen responsible for antibiotic-associated diarrhea, highlighting the role of exotoxins and methods for genetic typing such as MLST and whole genome sequencing (WGS).
  • A study analyzed 699 genome sequences of distinct strains to establish a core gene set and develop a core genome multilocus sequence typing (cgMLST) scheme for phylogenetic analysis.
  • The findings categorized the bacterial isolates into five clades and successfully tracked an outbreak, suggesting a valuable surveillance system for this pathogen in China.

Article Synopsis
  • A study was conducted in Shanghai to investigate the prevalence, genetic diversity, antibiotic resistance, and pathogenicity of strains isolated from food, as these strains have been recognized as emerging human pathogens associated with diarrhea worldwide.
  • A total of 79 food isolates were analyzed, revealing eight different species, with most being hemolytic and showing antibiotic resistance; specifically, 11.4% were multidrug-resistant and 93.7% were resistant to cefazolin.
  • The findings indicate that certain isolates are highly pathogenic, posing risks to public health, and emphasize the importance of monitoring food safety to improve prevention and treatment of diarrhea-related illnesses in China.

Article Synopsis
  • * The isolates showed high genetic diversity with 84 sequence types, 80 of which were novel, and were classified into eight species, with certain virulence genes found in over half of them.
  • * Most isolates were susceptible to several antibiotics, but some resistance genes and a new variant were also identified, indicating variability in antibiotic resistance and virulence among different sources.

Background: MicroRNAs (miRNAs) may play an important role in organ development, cell differentiation, apoptosis, proliferation, cell growth regulation and act as tumor suppressor genes or proto-oncogenes. Single nucleotide polymorphisms (SNPs) in miRNAs are considered to be genetic factors to influence the susceptibility to lung cancer (LC). Rs2910164 in miR-146a and rs11614913 in miR-196a2 are shown to be associated with increased/decreased LC risk.

Multilocus sequence typing (MLST) has proven to be an effective approach for the subtyping isolates of the Cronobacter genus and to exhibit a high level of discrimination between isolates. In this study, 151 Cronobacter strains were isolated from different sources and provinces across China from 2010 to 2012 and analyzed by MLST. Their sequence type profiles were compared with strains from other countries which were widely geographically and temporally distributed.

Background: To systematically summarize the association between the X-ray repair cross complementing 3 (XRCC3) gene polymorphism and oral cancer susceptibility by meta-analysis.

Materials And Methods: Databases including PubMed, EMbase, CNKI, VIP and WanFang Data were searched to identify case-control studies concerning the association between an XRCC3 gene polymorphism and the risk of oral cancer from the inception to June 2014. Two reviewers independently screened the literature according to the criteria, extracted the data and assessed the quality.
