42, 95% CI 0.85, 2.38), or between breastfeeding to sleep and ECC (PR 1.12, 95% CI 0.67, 1.88), although the direction of effect was suggestive of an association. The only factors independently associated with ECC were high free sugars intakes (PR 1.97, 95% CI 1.13, 3.44), and greater socioeconomic disadvantage (PR 2.15, 95% CI 1.08, 4.28). Most participants who were breastfed at 1 y of age had ceased by 18 mo or 2 y. CONCLUSIONS Breastfeeding practices were not associated with ECC. Given the wide-ranging benefits of breastfeeding, and the low prevalence of sustained breastfeeding in this study and Australia in general, recommendations to limit breastfeeding are unwarranted, and breastfeeding should be promoted in line with global and national recommendations. To reduce the prevalence of early childhood caries, improved efforts are needed to limit foods high in free sugars.

With the increasing study of human diseases and biological processes, information in human H3K27ac ChIP-seq, ATAC-seq and DNase-seq datasets is accumulating rapidly, resulting in an urgent need to collect and process data to identify transcriptional regulatory regions of lncRNAs. We therefore developed a comprehensive database for human regulatory information of lncRNAs (TRlnc, http//bio.licpathway.net/TRlnc), which aimed to collect available resources of transcriptional regulatory regions of lncRNAs and to annotate and illustrate their potential roles in the regulation of lncRNAs in a cell type-specific manner. The current version of TRlnc contains 8 683 028 typical enhancers/super-enhancers and 32 348 244 chromatin accessibility regions associated with 91 906 human lncRNAs. These regions are identified from over 900 human H3K27ac ChIP-seq, ATAC-seq and DNase-seq samples. Furthermore, TRlnc provides the detailed genetic and epigenetic annotation information within transcriptional regulatory regions (promoter, enhancer/super-enhancer and chromatin accessibility regions) of lncRNAs, including common SNPs, risk SNPs, eQTLs, linkage disequilibrium SNPs, transcription factors, methylation sites, histone modifications and 3D chromatin interactions. It is anticipated that the use of TRlnc will help users to gain in-depth and useful insights into the transcriptional regulatory mechanisms of lncRNAs. © The Author(s) 2020.

The Applied Biomarker in Late Effects of Childhood Cancer (ABLE/PBMTC1202, NCT02067832) study evaluated the immune profiles in chronic GvHD (cGvHD) and late acute GvHD (L-aGvHD). Peripheral blood immune cell and plasma markers were analyzed at day 100 after HSCT and correlated with GvHD diagnosed according to the NIH cGvHD consensus criteria (NIH-CC). Of 302 children enrolled, 241 were evaluable as a) L-aGvHD, b) cGvHD, c) active L-aGvHD or cGvHD, and d) no cGvHD/L-aGvHD. Significant marker differences, adjusted for major clinical factors, were defined as meeting all 3 criteria ROC AUC ≥0.60; p-value ≤0.05; and effect ratio ≥1.3 or ≤0.75. Patients with only distinctive features but determined as cGvHD by the adjudication committee (non-NIH-CC) had similar immune profiles to NIH-CC. Both cGvHD and late aGvHD had decreased transitional B cells and increased cytolytic NK cells. cGvHD had additional abnormalities, with increased activated T cells, naïve Th and Tc cells, a loss of CD56bright NKreg cells; and increased ST2 and sCD13. Active L-aGvHD before day 114 had additional abnormalities in naïve Th, naive Treg populations, and cytokines and active cGvHD an increase in PD-1- and decrease in PD1+ memory Treg cells. Unsupervised analysis appeared to show a progression of immune abnormalities from no cGvHD/L-aGvHD to L-aGvHD with the most complex pattern in cGvHD. Comprehensive immune profiling will allow us to better understand how to minimize late aGvHD and cGvHD. Further confirmation in adult and pediatric cohorts are needed.

Serial saliva viral load monitoring generally showed a declining trend. Live virus was detected in saliva by viral culture. Saliva is a promising non-invasive specimen for diagnosis, monitoring, and infection control in patients with 2019-nCoV infection. © The Author(s) 2020.

METHODS We searched multiple electronic databases and reference lists of articles dating up to August 2018 for prospective and retrospective studies comparing postoperative infection risk in patients treated with an IBD medication perioperatively with the risk in patients who were not taking that medication. Outcomes were overall infectious complications and intra-abdominal infections within 30 days of surgery. RESULTS Sixty-three studies were included. Overall infectious complications were increased in patients who received anti-tumor necrosis factor (TNF) agents (odds ratio [OR] 1.26; 95% confidence interval [CI], 1.07-1.50) and corticosteroids (OR 1.34; 95% CI, 1.25-1.44) and decreased in those who received 5-aminosalicylic acid (OR 0.63; 95% CI, 0.46-0.87). SCH58261 nmr No difference was observed in those treated with immunomodulators (OR 1.08; 95% CI, 0.94-1.25) or anti-integrin ag@oup.com.Animal carcinogenesis models induced by environmental chemicals have been widely used for basic and applied cancer research. However, establishment of in vitro or ex vivo models is essential for molecular mechanistic elucidation of early events in carcinogenesis, leading to clarification of the total mode of action. In the present study, to establish an organoid-based chemical carcinogenesis model, mouse organoids were treated in vitro with 4 genotoxic chemicals, e.g., ethyl methanesulfonate (EMS), acrylamide (AA), diethylnitrosamine (DEN) and 7,12-dimethylbenz[a]anthracene (DMBA) to examine their tumorigenicity after injection to nude mice. The 4 chemicals were reported to induce lung, liver or mammary carcinomas in mouse models. DMBA-treated mammary tissue-derived organoids with Trp53 heterozygous knockout exhibited tumorigenicity, but not those with wild-type Trp53, reflecting previous reports of corresponding animal models. Treatment of lung organoids with or without Trp53 knockout with EMS or AA resulted in carcinogenic histopathological characteristics, and the activation of oncogenic kinases was demonstrated in the nodules from the nude mouse subcutis.
