Provision of colonoscopy in rural settings: A qualitative assessment of provider context, barriers, facilitators, and capacity.

Purpose: Colonoscopy can prevent morbidity and mortality from colorectal cancer (CRC) and is the most commonly used screening method in the United States. Barriers to colonoscopy at multiple levels can contribute to disparities. Yet, in rural settings, little is known about who delivers colonoscopy and facilitators and barriers to colonoscopy access through screening completion.

The recalibration and redevelopment of a model to calculate patients' probability of completing a colonoscopy following an abnormal fecal test.

Objectives: Fecal immunochemical testing (FIT) is an effective screening tool for colorectal cancer. If an FIT is abnormal, a follow-up colonoscopy is necessary to remove polyps or find cancers. We sought to develop a usable risk prediction model to identify patients unlikely to complete a colonoscopy following an abnormal FIT test.

Precision Patient Navigation to Improve Rates of Follow-up Colonoscopy, An Individual Randomized Effectiveness Trial.

Background: Colorectal cancer screening by annual fecal immunochemical test (FIT) with follow-up on abnormal results is a cost-effective strategy to reduce colorectal cancer incidence and mortality. Unfortunately, many patients with abnormal results do not complete a follow-up colonoscopy. We tested whether navigation targeted to patients who are unlikely to complete the procedure may improve adherence and long-term outcomes.

Follow-up colonoscopy after an abnormal stool-based colorectal cancer screening result: analysis of steps in the colonoscopy completion process.

Background: Delays in receiving follow-up colonoscopy after an abnormal fecal immunochemical test (FIT) result are associated with increased colorectal cancer incidence and mortality. Little is known about patterns of follow-up colonoscopy completion in federally qualified health centers.

Methods: We abstracted the medical records of health center patients, aged 50-75 years, who had an abnormal FIT result between August 5, 2017 and August 4, 2018 (N = 711).

Positive predictive values of fecal immunochemical tests used in the STOP CRC pragmatic trial.

Annual fecal immunochemical testing (FIT) is cost-effective for colorectal cancer (CRC) screening. However, FIT positivity rates and positive predictive value (PPV) can vary substantially, with false-positive (FP) results adding to colonoscopy burden without improving cancer detection. Our objective was to describe FIT PPV and the factors associated with FP results among patients undergoing CRC screening.

Role of simple biomarkers in predicting fibrosis progression in HCV infection.

Aim: To examine the accuracy of the aspartate aminotransferase (AST)/Platelet Ratio Index (APRI) and FIB-4, in predicting longitudinal changes in liver histology in hepatitis C virus (HCV) patients.

Methods: Patients that underwent repeat liver biopsies at least 1 year apart from 1999 to 2007 were identified. Liver fibrosis was staged on needle core biopsies evaluated by a single expert liver pathologist.

Hepatotoxicity fears contribute to underutilization of statin medications by primary care physicians.

Introduction: The safety and efficacy of hydroxymethylglutaryl CoA reductase inhibitors (statins) have been extensively demonstrated, but in clinical practice, there remains significant underutilization of these medications. The authors hypothesized that this underutilization could stem in part from fear of liver damage caused by statins. The purpose was to determine whether concern about hepatotoxicity acts as a barrier among primary care physicians to prescribing statins for patients with elevated liver transaminase values and/or underlying liver disease.

Effect of bisphosphonates on bone mineral density in liver transplant patients: a meta-analysis and systematic review of randomized controlled trials.

Bone mineral density (BMD) loss after liver transplantation (LT) results in considerable morbidity with the increased risk of fractures. Data on the efficacy of bisphosphonate use in post LT patients is scarce. This meta-analysis aims to summarize the results from published randomized controlled trials (RCTs) on the topic of interest.

Effect of bariatric surgery on nonalcoholic fatty liver disease: systematic review and meta-analysis.

Background & Aims: Weight loss in overweight or obese individuals results in marked improvement or resolution of hypertension, diabetes mellitus, and hyperlipidemia. However, the overall effect of weight loss on nonalcoholic fatty liver disease (NAFLD) remains unclear. This systematic review and meta-analysis is an effort to explore the effect of weight loss after bariatric surgical procedures on NAFLD.

Neutropenic enterocolitis: An unusual complication of HCV combination therapy with PEG-IFN and ribavirin.

Drug induced neutropenia as a consequence of intensive chemotherapy for hematological malignancies and solid tumors is known to be associated with severe, life-threatening infections such as neutropenic enterocolitis. However, the neutropenia associated with HCV combination therapy with Pegylated Interferon [PEG-IFN] and ribavirin is considered to be well tolerated in patients without other co-morbidities. We present a case of a severe gastrointestinal complication in a patient receiving HCV combination therapy and advocate caution in continuing therapy in patients with neutropenia, especially in the presence of underlying co-morbidities such as cirrhosis.

The eagle or the snake: platforms for NOTES and radical endoscopic therapy.

It has only been about 3 years since natural orifice translumenal endoscopic surgery (NOTES) first began to gather the attention of the medical and surgical community at large. The concepts behind NOTES, however, have been under development for almost a decade. It is important to revisit some basic concepts regarding therapeutic flexible endoscopy and in the process understand the fundamental premises on which a sound technology development program for NOTES should be built.
