Objective: In this prospective cohort study, we aimed to evaluate the association between dietary habits and the risk of developing hepatocellular carcinoma (HCC) in hepatitis B surface antigen (HBsAg)‐positive carriers in Qidong, an hepatitis B virus (HBV)‐epidemic area in China. Methods: A total of 3199 HBsAg carriers aged 30‐70 years in a prospective cohort in Qidong, China from 2007 to 2011 were included in the study. At baseline, all participants self‐reported their dietary habits in a questionnaire interview. A follow‐up check‐up was performed every 6 months to identify HCC cases until November 2017. Cox's regression analysis and an interaction analysis were performed to estimate the relative risks of HCC in terms of baseline diet. Results: Among 3199 HBsAg‐positive participants, 270 developed HCC (143.86/100 000 person‐years [PYs]). Compared with participants who rarely consume garlic, the risk of HCC in those who consumed it ≥ once per week decreased along with the increase in frequency (HR = 1.00, 0.90 and 0.62 in those who consumed it rarely vs those who consumed it 1‐6 times per week and ≥ 7 times per week, respectively). This study found a synergistic effect between garlic and tea consumption on the risk of HCC (P = 0.039 for a multiplicative interaction). Conclusions: HBsAg carriers should improve their diet. Regular consumption of garlic and tea drinking may reduce the HCC incidence in HBsAg carriers. [ABSTRACT FROM AUTHOR]

Aim: This study explored the gut microbiota of children with hand, foot and mouth disease (HFMD).Methods: We enrolled 15 cases with HFMD admitted to the West China Second Hospital, Sichuan University, China, from July to September 2016 at a median age of three years. The controls were 15 healthy children of a similar age who underwent routine health examinations at the hospital during the same period. Gut microbiota was analysed using high throughput 16S ribosomal deoxyribonucleic acid sequencing.Results: The gut microbiota in the HFMD patients was distinct from the controls. Compared with the controls, the composition of gut microbiota in the HFMD cases represented a reduction of two butyrate-producing bacteria, Ruminococcus (0.73 ± 1.28 versus 7.78 ± 20.01, p = 0.026) and Roseburia (0.67 ± 1.69 versus 1.61 ± 3.27, p = 0.024) and an up-regulation of Escherichia (5.26 ± 10.50 versus 1.59 ± 5.90,p < 0.01) and Enterococcus (4.12 ± 12.49 versus 0.12 ± 0.41, p = 0.015).Conclusion: The dysbiosis of gut microbiota of the HFMD cases included a reduction of butyrate-producing bacteria and an up-regulation of inflammation-inducing bacteria. These may have impaired the intestinal biological mucosal barrier and host immune functions, promoting the invasion of the enterovirus. [ABSTRACT FROM AUTHOR]
