The evidence for the association between meat intake and the risk of bladder cancer (BC) is still inconclusive. A total of 29 studies involving 1,475,125 participants and 18,836 cases of BC were included in the meta-analysis. Among these studies, 11 reported total meat intake, 20 reported red meat intake, 19 reported processed meat intake, 15 reported white meat intake, and 15 reported fish intake. The results suggested that there was an overall increase in BC risk associated with total meat intake (RR = 1.10; 95% confidence interval: 0.92–1.31; I2 = 55.20%; P = 0.014), and a higher red meat (RR = 1.23; 95% CI: 1.08–1.39; I2 = 51.30%; P = 0.004) or processed meat (RR = 1.16; 95% CI: 1.08–1.25; I2 = 28.00%; P = 0.125) intake may increase the risk of BC. In contrast, a higher intake of fish (RR = 0.80; 95% CI: 0.67–0.95; I2 = 62.90%; P = 0.001) was inversely associated with the risk of BC. Moreover, we did not observe an association between white meat (RR = 0.96; 95% CI: 0.83–1.10; I2 = 53.70%; P = 0.007) and the risk of BC. Our findings suggested that dietary intervention may be an effective approach to preventing BC, which still needs to be confirmed by further well-designed observational studies.

The association between meat intake and hepatocellular carcinoma (HCC) risk is still unclear. We conducted a meta-analysis with observational studies to clarify this relationship. A total of 17 studies involving 2,915,680 participants and 4,953 cases of HCC were included in the meta-analysis. Ten studies reported red meat intake, nine reported white meat intake, nine reported fish intake, seven reported processed meat intake, and five reported total meat intake. The results showed that the consumption of red meat (relative risk [RR] = 1.04; 95% confidence interval [CI]: 0.91–1.18; I2=50.50%; P = 0.033) and total meat intake (RR = 1.01; 95% CI: 0.90–1.13; I2 = 15.50%; P = 0.316) were not associated with risk of HCC. However, a higher dietary intake of processed meat (RR = 1.20; 95% CI: 1.02–1.41; I2 = 26.30%; P = 0.228) may increase the risk of HCC. In contrast, the intake of white meat (RR = 0.76; 95% CI: 0.63–0.92; I2 = 68.30%; P = 0.001) and fish (RR = 0.91; 95% CI: 0.86–0.96; I2 =40.90%; P = 0.095) were inversely associated with risk of HCC. Our findings suggest that dietary intervention may be an effective approach to preventing HCC. These need to be verified with further well-designed observational studies and experimental clinical research. [ABSTRACT FROM AUTHOR]

The effects of soil salinity on growth, photosynthetic pigments, ion relations, and compatible solute accumulation of two sumac seedlings (Rhus glabraandRhus trilobata) treated with five salinity levels in a completely randomized block design with four replications were studied. Both species were inhibited by soil salinity, but salt-damaged symptoms appeared much earlier and more severely inR. glabra, and relative height growth rates (RGRH) and photosynthetic pigment contents were much higher on average inR. trilobata. The biomass increment, root/shoot ratio, and relative shoot dry weight (DW) were significantly affected only inR. glabra. Rhus trilobatashowed stable potassium (K+) concentration and low sodium (Na+) accumulation in roots, stems, and leaves, and a proline concentration 10 times greater than that ofR. glabra. Overall, our findings suggest thatR. trilobatais more salt-tolerant thanR. glabra, which is presumably rooted in its better performance in ionic homeostasis and osmotic regulation.
