Magnesium intake is associated with a reduced risk of incident liver cancer, based on an analysis of the NIH-American Association of Retired Persons (NIH-AARP) Diet and Health Study prospective cohort.
Liver cancer incidence and mortality are escalating globally. Magnesium intake has been studied extensively in nonmalignant liver pathology, but the association between dietary intake of magnesium and primary liver malignancy has not been previously evaluated. In this study, investigators aimed to determine the association between total magnesium intake and primary liver cancer risk. The investigators concluded that based on their prospective cohort analysis, magnesium intake was associated with a lower risk of primary liver cancer, which was more pronounced among moderate and heavy alcohol users.

Surgical patient values frame and modify the impact of risk factors for non-routine postdischarge care: a mixed-methods study.
This mixed methods study looked at patient perspectives on risk factors of non-routine postdischarge care (emergency department visit or rehospitalization) for adult colorectal surgery patients. Surgery patients were identified from hospital records from 2017 to 2018. The authors enrolled 258 participants, surveyed 167, and interviewed 18. Depressive symptoms were found to be one of the many risk factors confirmed to increase non-routine health utilization.

Reappraising risk factors for inflammatory bowel disease-associated neoplasia: implications for colonoscopic surveillance in IBD.
One of the most feared complications of inflammatory bowel disease [IBD]-associated colitis is colorectal cancer. An opportunity for early detection is being missed in a group that is overlooked as high-risk, as a substantial proportion of colorectal cancers are being diagnosed in individuals with colonic IBD who have disease duration shorter than when guidelines recommend surveillance initiation. In this study, the investigators discuss a viewpoint that supports a paradigm shift that will ideally result in a more effective and higher-value colorectal cancer prevention approach in IBD.

Associations between calcium and magnesium intake and the risk of incident gastric cancer: a prospective cohort analysis of the National Institutes of Health-American Association of Retired Persons (NIH-AARP) Diet and Health Study.
Gastric cancer remains a leading cause of cancer-related mortality. Identifying dietary and other modifiable disease determinants has important implications for risk attenuation in susceptible individuals. The primary aim of the investigators was to estimate the association between dietary and supplemental intakes of calcium and magnesium and the risk of incident gastric cancer. They conducted a prospective cohort analysis of the National Institutes of Health-American Association of Retired Persons Diet and Health Study.

Occupational exposures and odds of gastric cancer: a StoP project consortium pooled analysis.
Gastric cancer pathogenesis represents a complex interaction of host genetic determinants, microbial virulence factors and environmental exposures. The primary aim of this study was to determine the association between occupations/occupational exposures and odds of gastric cancer. Based on a large pooled analysis, the investigators identified several occupations and related exposures that were associated with elevated odds of gastric cancer.

Hirschsprung-associated enterocolitis in children treated at US children's hospitals.
The incidence of and risk factors for Hirschsprung's-associated enterocolitis (HAEC) following pull-through have been limited to single institutions studies. In this retrospective cohort study, the investigators characterized the incidence of, risk factors for, and consequences of post-operative HAEC. The investigators concluded that HAEC following pull-through occurs in a large proportion of infants with HD and predicts reoperation. They suggest that multicenter studies are needed to develop prediction models and treatment protocols for HAEC.

Late-onset Crohn's Disease is a subgroup distinct in genetic and behavioral risk factors with UC-like characteristics.
Age of onset is linked to variations in clinical phenotypes and natural history in Crohn's disease (CD). In this study, the investigators aimed to define etiologically more homogenous subgroups in CD based on ages of onset. The investigators concluded that late-onset CD was subgroup distinct in genetic and behavioral risk factors with UC-like characteristics.

The independent effect of cancer on outcomes: a potential limitation of surgical risk prediction.
This study aims to compare the use of common risk models for benign versus malignant gastrointestinal disease. It found that the National Surgical Quality Improvement Program (NSQIP) prediction models less effectively evaluate the risk of death in cancer patients as compared to patients with benign disease. A diagnosis of cancer is independently associated with an increased risk of surgical complications.

A frameshift in CSF2RB predominant among Ashkenazi Jews increases risk for Crohn's disease and reduces monocyte signaling via GM-CSF.
The authors sought to identify rare, Crohn's disease-associated frameshift variants of high functional and statistical effects. They associated Crohn's disease with a frameshift mutation in CSF2RB. Intestinal monocytes from carriers of this mutation had reduced responses to granulocyte-macrophage colony-stimulating factor.

A pleiotropic missense variant in SLC39A8 is associated with crohn's disease and human gut microbiome composition.
This study aimed to identify novel associations between inflammatory bowel disease (IBD) and functional genetic variants. The results suggest that an SLC39A8-dependent shift in the gut microbiome could explain its pleiotropic effects on multiple complex diseases including Crohn's disease.

Increased prevalence of inflammatory bowel disease in patients with mutations in genes encoding the receptor subunits for TGFbeta.
The researchers evaluated the potential genetic risk factors that could predict which patients with Loeys-Dietz syndrome (LDS) would develop inflammatory bowel disease (IBD). They reported a 10-fold increase in the prevalence of IBD in patients with LDS compared with the general population.

Comparison of frequency of inflammatory bowel disease and noninfectious gastroenteritis among statin users versus nonusers.
The objective of this study was to examine the association of statin use on the prevalence of IBD and noninfectious gastroenteritis (NI-GE) in a cohort of patients who were followed longitudinally in a military health care system, where patients had similar access and availability of health care. It found that statin use was not associated with either an increased or decreased risk of IBD or NI-GE diagnoses.
