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.

Early operative management of complicated appendicitis is associated with improved surgical outcomes in adults.
In this study, the New York State Planning and Research Cooperative database was used to identify all patients admitted with complicated appendicitis and undergoing appendectomy within 1-year. Primary outcome was any complication. Secondary outcomes included length of stay (LOS), hospital charges, and laparoscopy use. Outcomes were compared in appendectomy before or after 48h from admission. The investigators found more complications, longer LOS, and higher charges in patients undergoing delayed surgery.

Expert consensus to weight an adherence score for audit and feedback of practices that prevent necrotizing enterocolitis in very low birth weight infants.
Necrotizing enterocolitis (NEC) is a catastrophic abdominal complication threatening the life of premature infants, but adoption of prevention and early recognition practices differs as do NEC rates in Neonatal Intensive Care Units (NICUs). The purpose of this research was to validate and weight an evidence-based adherence score (aka NEC-Zero Adherence Score) to prevent and foster timely recognition of NEC.

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.

Association between breast cancer recurrence and immunosuppression in rheumatoid arthritis and inflammatory bowel disease: a cohort study.
The researchers examined the rates of breast cancer recurrence in patients with immune-mediated disease and treated breast cancer who received therapy with methotrexate, thiopurines, or anti-tumor necrosis factor (anti-TNF). They found that the risk of breast cancer recurrence in patients who received methotrexate, thiopurine, or anti-TNF therapy was not statistically significantly increased, although they did not rule out a 2-fold or greater increased risk in those treated with thiopurines.

Incidence of hepaticojejunostomy stricture after hepaticojejunostomy.
The authors aimed to determine the timing, incidence, and management of stricture after biliary-enteric anastomosis. They found that younger age was associated with a decreased likelihood of stricture formation and that the presence of an endostent predicted stricture formation. They concluded that biliary-enteric anastomotic strictures occur with significant frequency after a biliary-enteric anastomosis, and that while many patients are managed nonoperatively, stricture diagnosis remains burdensome.

Age disparities in the use of steroid-sparing therapy for inflammatory bowel disease.
The investigators compared the use of steroids and steroid-sparing therapies and rates of complications among elderly and younger patients in a national cohort of veterans with inflammatory bowel disease (IBD). They found that, after starting steroids, fracture rates increased in the elderly patients with IBD, whereas increases in venous thromboembolism and infections after starting steroids affected both age groups. Additonally, elderly veterans were less likely to receive steroids and steroid-sparing medications than younger veterans.

Number of diverticulitis episodes before resection and factors associated with earlier interventions.
The authors described patterns of episodes of diverticulitis before surgery and factors associated with earlier interventions using inpatient, outpatient, and antibiotic prescription claims. They found that 56.3% of elective resections for uncomplicated diverticulitis occurred after fewer than 3 episodes. Further, they determined that earlier surgery was not explained by younger age, laparoscopy, time between the last 2 episodes preceding surgery, or financial risk-bearing for patients.

Pharmacodynamic assessment of vedolizumab for the treatment of ulcerative colitis.
This review discusses the chemistry, pharmacologic properties, clinical efficacy, and safety of vedolizumab in ulcerative colitis. It concluded that vedolizumab is a promising new agent for the treatment of ulcerative colitis. Its mechanism of action differs from tumor necrosis factor (TNF)-alpha inhibitors and immune suppressants, allowing it to be used in cases of TNF-alpha inhibitor failure or non-response, or as a first-line biologic drug.

Association of systemic sclerosis with a unique colonic microbial consortium.
The authors compared colonic microbial composition in systemic sclerosis (SSc) patients and healthy controls and determined whether certain microbial genera are associated with gastrointestinal (GI) tract symptoms in patients with SSc. They found that SSc patients had decreased levels of commensal bacteria and increased levels of pathobiont bacteria compared with healthy controls. They concluded that this unique ecologic change may perpetuate immunologic aberrations and contribute to clinical manifestations of SSc.

Alvimopan use, outcomes, and costs: a report from the Surgical Care and Outcomes Assessment Program Comparative Effectiveness Research Translation Network Collaborative.
The researchers investigated the effectiveness of alvimopan in routine clinical practice and its impact on hospital costs. They found that when used in routine clinical practice, alvimopan was associated with a shorter length of stay and limited but significant hospital cost savings. They concluded that both efficacy and effectiveness data support the use of alvimopan in routine clinical practice, and its use could be measured as a marker of higher quality care.
