Both community mobilization and media campaigns significantly increased the knowledge of Vietnamese-American parents about hepatitis B vaccination, and the receipt of "catch-up" vaccinations among their children.

Background Few population-based studies have evaluated the influence of long-term diet on the gut microbiome, and data among Asian populations are lacking. Objective We examined the association of long-term diet quality, comprising 8 food groups (fruit, vegetables, dairy, fish/seafood, nuts/legumes, refined grains, red meat, and processed meat), with gut microbiome among Chinese adults. Methods Included were 1920 men and women, enrolled in 2 prospective cohorts (baseline 1996–2006), who remained free of cardiovascular diseases, diabetes, and cancer at stool collection (2015–2018) and had no diarrhea or antibiotic use in the last 7 d before stool collection. Microbiome was profiled by 16S rRNA sequencing. Long-term diet was assessed by repeated surveys at baseline and follow-ups (1996–2011), with intervals of 5.2 to 20.5 y between dietary surveys and stool collection. Associations of dietary variables with microbiome diversity and composition were evaluated by linear or negative binomial hurdle models, adjusting for potential confounders. False discovery rate (FDR) <0.1 was considered significant. Results The mean ± SD age at stool collection was 68 ± 1.5 y. Diet quality was positively associated with microbiome α-diversity (P = 0.03) and abundance of Firmicutes, Actinobacteria, Tenericutes, and genera/species within these phyla, including Coprococcus, Faecalibacterium/Faecalibacterium prausnitzii, Bifidobacterium / Bifidobacterium adolescentis, and order RF39 (all FDRs <0.1). Significant associations were also observed for intakes of dairy, fish/seafood, nuts/legumes, refined grains, and processed meat, including a positive association of dairy with Bifidobacterium and inverse associations of processed meat with Roseburia /Roseburia faecis. Most associations were similar, with or without adjustment for BMI and hypertension status or excluding participants with antibiotic use in the past 6 mo. Conclusion Among apparently healthy Chinese adults, long-term diet quality is positively associated with fecal microbiome diversity and abundance of fiber-fermenting bacteria, although magnitudes are generally small. Future studies are needed to examine if these bacteria may mediate or modify diet–disease relations.

Evidence from animal models suggests that dietary fatty acids have both anticancer and tumor-promoting effects. Whether dietary fatty acids are associated with colorectal cancer (CRC) in humans remains inconclusive. We investigated associations between dietary fatty acids and risk of CRC among 59 986 men who participated in the Shanghai Men's Health Study (SMHS), an ongoing population-based prospective cohort study. We identified 876 incident CRC cases in the SMHS during a mean follow-up of 9.8 years. Associations between dietary fatty acid intake and CRC risk were evaluated by Cox proportional hazard regression analyses. Consumption of saturated fatty acids (SFA), monounsaturated fatty acids (MUFA) and polyunsaturated fatty acids (PUFA) was not significantly associated with CRC risk. Multivariate hazard ratios (HRs) and respective 95% confidence intervals (CIs) for Quartile 4 vs Quartile 1 were 0.92 (0.74-1.14; P trend = 0.47) for SFA, 0.95 (0.79-1.16; P trend = 0.74) for MUFA and 1.18 (0.95-1.46; P trend = 0.21) for PUFA. No significant associations were found for total n-6 PUFA or total n-3 PUFA. Additionally, we performed a metaanalysis to summarize results from the present study and 28 reports from 26 additional cohorts, which supported the overall null association between dietary fatty acid intake and CRC risk among men. Docosahexanoic acid and eicosapentaenoic acid were associated with 11% to 12% reduced risk, and linoleic acid a 19% increased risk, of CRC in the meta-analysis of combined sexes. In conclusion, this populationbased prospective study and meta-analysis of cohort studies found little evidence that dietary fatty acid intake was associated with risk of CRC in men.

We describe an infant male of Cambodian background who has typical craniofacial features of mycophenolate mofetil (MMF) embryopathy and a complex congenital heart defect (CHD) (double outlet right ventricle, mitral atresia, pulmonic stenosis, and total anomalous pulmonary venous return). Together with four case reports and the 20 patients included in two recent reviews, we report 24 (19 affected, five normal) patients with this pattern of anomalies. Eight (33%) have a CHD, most commonly, conotruncal or aortic arch defects (6/8, 75%). This would support the hypothesis that disturbance of cranial neural crest migration occurs in exposed infants, and may predict which additional anomalies will be observed in the future. We also attempted to score the severity of the facial anomalies in each MMF patient using a system created by plastic surgeons for patients with hemifacial microsomia. This classification had modest utility in comparing severity and correlating facial to extracranial defects. The findings are viewed with caution because of the preliminary methodology. Finally, since several exposed infants have been reported to be minimally affected, we remind clinicians to be sensitive to the potential mild expression of the effects of this teratogen. This awareness may influence clinical management of apparently normal MMF-exposed individuals.
