Provider Adherence to the 2020 US Multi-Society Task Force Guidelines for Surveillance After Colonoscopy With Polypectomy.

Background And Aims: The 2020 United States Multi-Society Task Force on Colorectal Cancer guidelines for surveillance after colonoscopy with polypectomy introduced significant changes in surveillance intervals. We sought to identify rates of adherence to these new guidelines at an academic medical center.

Methods: Average-risk screening colonoscopies where 1 to 4 polyps <10 mm were removed between January 1, 2020, and June 30, 2021 were included.

Variation in responses to incretin therapy: Modifiable and non-modifiable factors.

Type 2 diabetes (T2D) and obesity have reached epidemic proportions. Incretin therapy is the second line of treatment for T2D, improving both blood glucose regulation and weight loss. Glucagon-like peptide-1 (GLP-1) and glucose-stimulated insulinotropic polypeptide (GIP) are the incretin hormones that provide the foundations for these drugs.

Leveraging electronic medical record functionality to capture adenoma detection rate.

Measuring the adenoma detection rate (ADR) is critical to providing quality care, however it is also challenging. We aimed to develop a tool using pre-existing electronic health record (EHR) functions to accurately and easily measure total ADR and to provide real-time feedback for endoscopists. We utilized the Epic EHR.

Histology, Size, and Number of Advanced Polyps are Associated With Guideline-Discordant Surveillance Recommendations.

Surveillance guidelines following polypectomy promote cost-effective reductions in future colorectal cancer (CRC) risk, but high nonadherence rates can have negative consequences on costs and effectiveness. Professional societies recommend a 3-year interval for patients with advanced colorectal polyps (ACPs), although few studies report provider adherence to surveillance intervals. This study evaluated rates and predictors of guideline-discordant recommendations for patients with ACPs.

Poor Knowledge of Personal and Familial Colorectal Cancer Risk and Screening Recommendations Associated with Advanced Colorectal Polyps.

Background And Aims: Advanced colorectal polyps (adenoma or sessile serrated polyp ≥ 1 cm, adenoma with villous features, adenoma with high-grade dysplasia, or any sessile serrated polyps with dysplasia) are associated with an increased risk of future advanced colorectal neoplasia and confer an increased risk of advanced neoplasia to first-degree family members. Professional societies therefore recommend more intensive surveillance of these polyps and earlier screening for first-degree relatives. The aim of this study was to assess knowledge of personal and familial risk and recommendations among patients with advanced colorectal polyps and identify predictors of knowledge.

Predictors of Failed Conscious Sedation in Patients Undergoing an Outpatient Colonoscopy and Implications for the Adenoma Detection Rate.

Guidelines to triage patients to conscious sedation (CS) or monitored anaesthesia care (MAC) for colonoscopy do not exist. We aimed to identify the CS failure rate, predictors of failure, and its impact on the adenoma detection rate (ADR). Strict (based on patient experience) and expanded (based on doses of sedative medications) definitions of CS failure were used.

Training Mentor-Mentee Pairs to Build a Robust Culture for Mentorship and a Pipeline of Clinical and Translational Researchers: The Colorado Mentoring Training Program.

The Colorado Mentoring Training program (CO-Mentor) was developed at the University of Colorado Anschutz Medical Campus in 2010, supported by the Colorado Clinical and Translational Sciences Institute. CO-Mentor represents a different paradigm in mentorship training by focusing equally on the development of mentees, who are valued as essential to institutional capacity for effective mentorship. The training model is unique among Clinical and Translational Science Award sites in that it engages mentors and mentees in an established relationship.

A compartmentalized type I interferon response in the gut during chronic HIV-1 infection is associated with immunopathogenesis.

Objective(s): Type I interferon (IFN-I) responses confer both protective and pathogenic effects in persistent virus infections. IFN-I diversity, stage of infection and tissue compartment may account for this dichotomy. The gut is a major site of early HIV-1 replication and microbial translocation, but the nature of the IFN-I response in this compartment remains unclear.

Association of Proton Pump Inhibitor Use With Serum Biomarkers of Inflammation, Insulin Resistance, Cardiovascular Risk, and Renal Function.

Background And Goals: Proton pump inhibitor (PPI) use has been associated with cardiovascular disease, chronic kidney disease, and dementia. Prior studies did not account for key confounders and little is known about the association of PPIs with serum biomarkers of inflammation, insulin resistance, cardiovascular risk, and renal function. Our aims were to investigate differences in these biomarkers between PPI users and nonusers.

Brief Report: Inflammatory Colonic Innate Lymphoid Cells Are Increased During Untreated HIV-1 Infection and Associated With Markers of Gut Dysbiosis and Mucosal Immune Activation.

Background: HIV-1 infection is associated with intestinal inflammation, changes in the enteric microbiota (dysbiosis), and intestinal epithelial cell damage. NKp44 innate lymphoid cells (ILCs) play an important role in epithelial barrier maintenance through the production of interleukin (IL)-22 but also display functional plasticity and can produce inflammatory cytokines [eg, interferon gamma (IFNγ)] in response to cytokine milieu and stimulatory signals. The objective of this pilot study was to enumerate frequencies of IL-22 and IFNγ-expressing colonic NKp44 ILCs during untreated, chronic HIV-1 infection.

A low-volume polyethylene glycol solution was associated with an increased suboptimal bowel preparation rate but had similar recommendations for an early repeat colonoscopy, procedure times, and adenoma detection rates.

Background/aims: Low-volume polyethylene glycol (PEG) bowel preparations are better tolerated by patients than high-volume preparations and may achieve similar preparation quality. However, there is little data comparing their effects on a recommendation for an early repeat colonoscopy (because of a suboptimal preparation), procedure times, adenoma detection rate (ADR), and advanced adenoma detection rate (AADR).

Methods: This is a retrospective cohort study of outpatient colonoscopies performed during a one-year period at a single academic medical center in which low-volume MoviPrep® (n = 1841) or high-volume Colyte® (n = 1337) was used.

Low abundance of colonic butyrate-producing bacteria in HIV infection is associated with microbial translocation and immune activation.

Objective: Gut microbial translocation is a major driving force behind chronic immune activation during HIV-1 infection. HIV-1-related intestinal dysbiosis, including increases in mucosa-associated pathobionts, may influence microbial translocation and contribute to mucosal and systemic inflammation. Thus, it is critical to understand the mechanisms by which gut microbes and their metabolic products, such as butyrate, influence immune cell function during HIV-1 infection.

Per-oral video cholangiopancreatoscopy with narrow-band imaging for the evaluation of indeterminate pancreaticobiliary disease.

Background And Aims: Cholangiopancreatoscopy for evaluating pancreaticobiliary pathology is currently limited by suboptimal optics. The aim of this study was to characterize the operating characteristics of per-oral video cholangiopancreatoscopy with narrow-band imaging (POVCP) findings in indeterminate pancreaticobiliary disease and to describe their association with neoplasia.

Methods: Data from consecutive patients undergoing POVCP for the evaluation of indeterminate pancreaticobiliary disease at a single tertiary care center were analyzed.

Intracellular Tenofovir and Emtricitabine Anabolites in Genital, Rectal, and Blood Compartments from First Dose to Steady State.

The pharmacokinetics (PK) of tenofovir-diphosphate (TFV-DP) and emtricitabine-triphosphate (FTC-TP), the active anabolites of tenofovir disoproxil fumarate (TDF), and emtricitabine (FTC) in blood, genital, and rectal compartments was determined in HIV-positive and seronegative adults who undertook a 60-day intensive PK study of daily TDF/FTC (plus efavirenz in HIV positives). Lymphocyte cell sorting, genital, and rectal sampling occurred once per subject, at staggered visits. Among 19 HIV-positive (3 female) and 21 seronegative (10 female) adults, TFV-DP in peripheral blood mononuclear cells (PBMC) accumulated 8.

Medicare Under Age 65 and Medicaid Patients Have Poorer Bowel Preparations: Implications for Recommendations for an Early Repeat Colonoscopy.

Background/aims: Colonoscopy is performed on patients across a broad spectrum of demographic characteristics. These characteristics may aggregate by patient insurance provider and influence bowel preparation quality and the prevalence of adenomas. The purpose of this study was to evaluate the association of insurance status and suboptimal bowel preparation, recommendation for an early repeat colonoscopy due to suboptimal bowel preparation, adenoma detection rate (ADR), and advanced ADR (AADR).

Pancreatic Duct Changes in Patients With Chronic Pancreatitis Treated With Polyethylene and Sof-Flex Material Stents: A Blinded Comparison.

Objectives: Pancreatic stenting is used to improve painful, obstructive chronic pancreatitis. Data suggest that polyethylene stents (PESs) cause stent-associated changes (SACs). Whether a stent composed of more flexible material (Sof-Flex stent [SFS]) is associated with less SAC is unknown.

Antidepressant Use is Associated with Increased Energy Intake and Similar Levels of Physical Activity.

Antidepressants have been associated with weight gain, but the causes are unclear. The aims of this study were to assess the association of antidepressant use with energy intake, macronutrient diet composition, and physical activity. We used data on medication use, energy intake, diet composition, and physical activity for 3073 eligible adults from the 2005-2006 National Health and Nutrition Examination Survey (NHANES).

Association of Proton Pump Inhibitor (PPI) Use with Energy Intake, Physical Activity, and Weight Gain.

Studies suggest proton pump inhibitor (PPI) use impacts body weight regulation, though the effect of PPIs on energy intake, energy extraction, and energy expenditure is unknown. We used data on 3073 eligible adults from the National Health and Nutrition Examination Survey (NHANES). Medication use, energy intake, diet composition, and physical activity were extracted from NHANES.

Acid suppression medications are associated with suboptimal weight loss after laparoscopic Roux-en-Y gastric bypass in patients older than 40 years.

Background: Bariatric surgery, including laparoscopic Roux-en-Y gastric bypass (LRYGB), achieves the greatest long-term weight loss in severe obesity. Approximately 50%-60% of severely obese patients have gastroesophageal reflux disease, and a substantial proportion is taking a proton pump inhibitor (PPI) or histamine-2 blocker (H2 B) at the time of LRYGB. The objective of this study was to explore the association of PPI/H2 B use before LRYGB with suboptimal percent weight loss (PWL) after LRYGB.

The effect of Medicaid status on weight loss, hospital length of stay, and 30-day readmission after laparoscopic Roux-en-Y gastric bypass surgery.

Background: Patients with Medicaid are much less likely to undergo bariatric surgery compared to those with commercial insurance. The aims of this study were to compare outcomes after laparoscopic Roux-en-Y gastric bypass (LRYGB) for patients covered by Medicaid, other (non-Medicaid) government insurance, and commercial insurance.

Methods: This was a retrospective cohort study of all eligible patients who underwent LRYGB between July 2004 and October 2011 at a single university hospital (n = 450).

The effect of PPI use on human gut microbiota and weight loss in patients undergoing laparoscopic Roux-en-Y gastric bypass.

Laparoscopic Roux-en-Y gastric bypass (LRYGB) achieves sustainable weight loss possibly by altering the gut microbiota. The effect of a proton pump inhibitor (PPI) on weight loss and the gut microbiota has not been explored. PPI use and the gut microbiota were assessed before and 6 months after LRYGB in eight patients.
