Background: Inflammatory bowel disease (IBD) affects many individuals of reproductive age. Most IBD medications are safe to use during pregnancy and breastfeeding; however, observational studies find that women with IBD have higher rates of voluntary childlessness due to fears about medication use during pregnancy. Understanding why and how individuals with IBD make decisions about medication adherence during important reproductive periods can help clinicians address patient fears about medication use.

Despite growing interest in remote patient monitoring, limited evidence exists to substantiate claims of its ability to improve outcomes. Our aim was to evaluate randomized controlled trials (RCTs) that assess the effects of using wearable biosensors (e.g.

Objectives: Access to the Internet has grown dramatically over the past two decades. Using data from a population-based survey, we aimed to determine the prevalence and predictors of (i) access to the Internet, and (ii) use of the Internet to search for health information.

Methods: We analyzed data from the 2011-12 California Health Interview Survey (CHIS) and included all individuals 18 years of age and older.

Background: Few studies have examined inflammatory bowel disease (IBD) patients' knowledge and understanding of biologic therapies outside traditional surveys. Here, we used social media data to examine IBD patients' understanding of the risks and benefits associated with biologic therapies and how this affects decision-making.

Methods: We collected posts from Twitter and e-forum discussions from >3000 social media sites posted between June 27, 2012 and June 27, 2015.

Background: Improvements in software and design and reduction in cost have made virtual reality (VR) a practical tool for immersive, three-dimensional (3D), multisensory experiences that distract patients from painful stimuli.

Objective: The objective of the study was to measure the impact of a onetime 3D VR intervention versus a two-dimensional (2D) distraction video for pain in hospitalized patients.

Methods: We conducted a comparative cohort study in a large, urban teaching hospital in medical inpatients with an average pain score of ≥3/10 from any cause.

Objectives: The National Institutes of Health (NIH) created the Patient Reported Outcomes Measurement Information System (PROMIS) to allow efficient, online measurement of patient-reported outcomes (PROs), but it remains untested whether PROMIS improves outcomes. Here, we aimed to compare the impact of gastrointestinal (GI) PROMIS measures vs. usual care on patient outcomes.

Background: Virtual reality (VR) offers immersive, realistic, three-dimensional experiences that "transport" users to novel environments. Because VR is effective for acute pain and anxiety, it may have benefits for hospitalized patients; however, there are few reports using VR in this setting.

Objective: The aim was to evaluate the acceptability and feasibility of VR in a diverse cohort of hospitalized patients.

Background And Aims: Status 1A patients are prioritized over end-stage liver disease (ESLD) for liver transplantation (LT). ESLD patients with high MELD may have higher waitlist mortality than Status 1A patients, and may require LT more urgently.

Methods: Using United Network for Organ Sharing registry data, we retrospectively evaluated LT waitlist mortality and probability of LT between adults in the United States with Status 1A or ESLD with MELD >30 listed for LT from 2003-2013.

Aim: Cholangiocarcinoma (CCA) is an uncommon but lethal malignancy with an increasing worldwide incidence of intrahepatic cholangiocarcinoma (ICC), but decreasing incidence of extrahepatic cholangiocarcinoma (ECC). To evaluate age-specific, sex-specific, race/ethnicity-specific variations in CCA incidence in the USA.

Methods: Using population-based cancer registry data from the 2000-2011 Surveillance, Epidemiology and End Results registry, we retrospectively evaluated age-specific, sex-specific, race/ethnicity-specific variations in incidence and prevalence of CCA stratified by ICC and ECC subtypes among adults in the USA.

Purpose Of Review: Diverticular disease is the most commonly reported finding at the time of colonoscopy and one of the most common gastrointestinal indications for hospitalization. Much of our previous understanding of diverticular disease has recently been challenged.

Recent Findings: There is emerging evidence that the long-accepted hypothesis of diverticulosis as a consequence of fiber deficiency may be more complex than commonly thought, with recent evidence suggesting that high-fiber diet and frequent bowel movements are associated with a greater and not lower prevalence of diverticular disease.

Pesticide handlers and pet owners who use products such as shampoos and dips and insecticide-impregnated collars to treat and control fleas on companion animals are exposed to a variety of active ingredients. Chlorpyrifos exposures of adults and children were measured using urine biomonitoring following use of over-the-counter products on dogs. Age and gender-specific measurements of urinary 3, 5, 6-trichloro-2-pyridinol (TCPy) revealed modest elevations of biomarker excretion following shampoo/dips.

The purpose of this study was to evaluate the effects of bleached kraft mill effluent on selected physiological and hematological endpoints in fingerling largemouth bass (Micropterus salmoides). Fish were exposed for 35 days to surface water collected at sites up- and downstream from a pulp and paper mill treatment-effluent discharge. The condition factor, spleen somatic index, and pronephros cellularity were statistically significantly decreased in fish exposed to the downstream site, compared to the upstream site.

Previous studies in channel catfish identified a novel cDNA encoding the cytochrome P450 isoform, CYP2X1. To characterize the substrate specificity of CYP2X1, the 57 kDa protein was expressed in Sf9 cells. Microsomes from Sf9 cells transfected with CYP2X1 demonstrated a maximum carbon monoxide-reduced difference spectrum at 450 nm and catalyzed aminopyrine and benzphetamine demethylase activity with catalytic efficiency (Vmax/Km) values of 0.
