Limitations of the review and meta-analysis of fish and PUFA intake and mild-to-severe cognitive impairment risks: a dose-response meta-analysis of 21 cohort studies
Limitation meta-analysis of fish 21 cohort studies
2018/12/13
The recent meta-analysis by Zhang et al. (1) on fish and PUFA intake and the risk of mild-to-severe cognitive impairment raises several methodologic issues that have important implications for the int...
Impairment of a speed management strategy in young drivers under high cognitive workload
Episodic training Young drivers Cognitive workload Cognitive resources Speed management
2012/4/26
From an applied perspective, these results suggest driver training programmes should compartmentalize driver training in order to reduce the cognitive load experienced by trainee drivers, and hence fa...
Occupational Exposure to Paints Causes Impairment of Kidney Functions
Organic Solvents Uric Acid Creatinine BUN Kidney
2013/3/12
It has been suggested that exposure to organic solvents may have a role in the impairment of kidney function that may progress to kidney failure. However, this has never been evaluated with an appropr...
