The clinical epidemiological features of cognitive impairment in Chinese older adult patients undergoing hemodialysis are not clear, we aimed to identify the extent and patterns of cognitive impairment among those patients. We conducted a cross-sectional study of 613 hemodialysis patients aged 50 to 80 from 11 centers in Beijing. A neuropsychological battery of 11 tests covering domains of attention/processing speed, executive function, memory, language, and visuospatial function was applied, patients were classified as none, mild, or major cognitive impairment according to the fifth version of the Diagnostic and Statistical Manual of Mental Disorders criteria for cognitive impairment. Compared with Chinese population norms, 37.2% of the participants had mild cognitive impairment, 43.7% had major cognitive impairment. Memory and language were the most severe impaired domains in the mild cognitive impairment group, attention and visuospatial function domains were the most serious impaired domains in the major cognitive impairment group. Concomitant impairment across multiple cognitive domains was common. Factors associated with major cognitive impairment included age, education level, history of stroke and hypertension, dialysis vintage, and single-pool Kt/V. There is a high frequency of cognitive impairment in Chinese older adult hemodialysis patients, with varying severity and concomitant impairment across multiple domains.

Background/aim: Although the advent of Helicobacter pylori eradication and global societal changes are widely assumed to impact on gastric cancer (GC)-related mortality, there is remarkable little quantitative and qualitative insight into the nature of its effects. Here, we exploited a nationwide reporting system to investigate the epidemiological features of GC-related mortality in China between 2006 and 2013.

Patients And Methods: GC mortality data between 2006 and 2013 were obtained from the National Disease Surveillance System published by the China Center for Disease Control and Prevention (CDC).

Results: GC mortality increased by 8.2% (from 18.87/100,000 to 20.41/100,000), while GC mortality standardized by the age scale of the population in 2010 decreased by 17.8% (from 21.87/100,000 to 17.98/100,000). Standardized GC mortality in males (25.66/100,000 to 33.89/100,000) was higher compared to females (10.72/100,000 to 14.79/100,000), while standardized GC mortality in rural areas (19.17/100,000 to 26.46/100,000) was higher than in urban areas (15.48/100,000 to 20.04/100,000). Both crude and standardized rates in the 0- to 29-year-old group increased by 22.3% and 16.2%, respectively; while these rates declined in the 30- to 59-year-old group and over 60-year-old group. The proportion of GC deaths that accounts for all cancer deaths declined from 15.99% (2006) to 13.6% (2013); however, the proportion in the 0- to 29-year-old group revealed an increasing trend from 2006 (3.20%) to 2013 (3.87%).

Conclusion: Our results reveal a remarkable increase in GC-related mortality in subjects under the age of 30 calling for further measures to prevent the increase in the incidence of GC in young patients.
