More than telemonitoring: Health provider use and nonuse of life-log data in irritable bowel syndrome and weight management.
The researchers sought to develop an in-depth understanding of providers’ facilitators and barriers to successfully integrating life-log data into their practices and creating better experiences. Providers reported using self-monitoring data to enhance provider-patient communication, develop personalized treatment plans, and to motivate and educate patients, in addition to using them as diagnostic and adherence tools. Barriers included a lack of time to review detailed records and questions about providers' expertise to review it.

Mortality associated with medical therapy versus elective colectomy in ulcerative colitis: a cohort study.
This study sought to determine whether patients with advanced ulcerative colitis (UC) treated with elective colectomy have improved survival compared with those treated with medical therapy. It found that elective colectomy was associated with improved survival compared with long-term medical therapy, although this result did not remain statistically significant in all sensitivity analyses.

Validity of diagnostic codes and laboratory tests of liver dysfunction to identify acute liver failure events.
The researchers examined positive predictive values (PPVs) of hospital ICD-9 diagnoses and laboratory tests of liver dysfunction for identifying acute liver failure (ALF) within a large, community-based integrated care organization. They found that algorithms comprising relevant hospital diagnoses, laboratory evidence of liver dysfunction, and prescriptions for hepatic encephalopathy treatment had low PPVs for confirmed (ALF) events. Studies of ALF will need to rely on medical records to confirm this outcome.

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.

TELEmedicine for Patients with Inflammatory Bowel Disease (TELE-IBD): design and implementation of randomized clinical trial.
This study compares disease activity and quality of life over 1 year in a randomized trial of IBD patients receiving standard care versus telemedicine. If effective, telemedicine should decrease symptoms, improve quality of life, and decrease health care utilization. The burden associated with use of telemedicine for patients and providers needs to be assessed. This trial is ongoing and will be completed in July 2016.

Comparative effectiveness of immunosuppressants and biologics for inducing and maintaining remission in Crohn's disease: a network meta-analysis.
The authors compared therapies for induction and maintenance of remission in patients with Crohn's disease. They found that adalimumab and infliximab + azathioprine are the most effective therapies for induction and maintenance of remission of Crohn's disease.

High-density mapping of the MHC identifies a shared role for HLA-DRB1*01:03 in inflammatory bowel diseases and heterozygous advantage in ulcerative colitis.
Studies in inflammatory bowel diseases (IBD) have indicated that multiple independent associations exist at human leukocyte antigen (HLA) and non-HLA genes, but they have lacked the statistical power to define the architecture of association and causal alleles. To address this, the researchers performed high-density single nucleotide polymorphism (SNP) typing of the major histocompatibility complex in >32,000 individuals with IBD.

Disease-specific alterations in the enteric virome in inflammatory bowel disease.
The researchers show that the enteric virome is abnormal in Crohn's disease (CD) and ulcerative colitis (UC) patients. Their data support a model in which changes in the virome may contribute to intestinal inflammation and bacterial dysbiosis. They conclude that the virome is a candidate for contributing to, or being a biomarker for, human inflammatory bowel disease and speculate that the enteric virome may play a role in other diseases.

Development and pilot testing of an integrated, web-based self-management program for irritable bowel syndrome (IBS).
The researchers developed, assessed, and refined an integrated IBS self-management program (IBS Self-care) and then conducted a 12-week pilot test. They found that the IBS Self-Care program was well received by users who after 12 weeks reported improved knowledge about IBS, but no significant changes in self-efficacy or quality of life.

Seasonality and pediatric inflammatory bowel disease.
The researchers sought to determine whether disease activity in pediatric-onset inflammatory bowel disease (IBD) is associated with a seasonal pattern. Studying 1325 patients with Crohn disease and 587 patients with ulcerative colitis, their findings do not support any strong associations between season of the year and disease activity in pediatric IBD.

Spatial and temporal stability of paneth cell phenotypes in Crohn's disease: implications for prognostic cellular biomarker development.
The researchers sought to develop Paneth cell phenotype as a prognostic biomarker in Crohn’s disease by additional characterization building on their earlier research. Specifically, they examined the effects of disease activity, phenotype duration, and the minimal crypt number that would allow for accurate Paneth cell phenotyping. They demonstrated that Paneth cell phenotypes are not affected either by disease activity or by exposure to therapeutic agents.

Harnessing claims to improve detection of surgical site infections following hysterectomy and colorectal surgery.
The researchers conducted retrospective cohort studies at 2 academic medical centers, extending analyses of patients undergoing hysterectomy or colorectal surgery. They concluded that claims-enhanced surveillance can help to identify surgical site infections (SSIs) missed by routine surveillance, identifying nearly twice as many SSIs following hysterectomy and 4 times more SSIs following colorectal surgery.
