Colorectal Cancer Screening Modalities in the US: Regional and Rural Variance, the Resilience of Colonoscopy, and the Rise of mt-sDNA Testing.

This study examined trends in colorectal cancer (CRC) screening modality utilization across the United States from 2016 to 2022, leveraging a large national claims database. The purpose was to identify national, regional, and demographic patterns in screening behavior during a period that encompassed the introduction of multitarget stool DNA testing (mt-sDNA) and the COVID-19 pandemic. Among 6.

Lipid membrane-camouflaged biomimetic nanoparticle for MicroRNA based therapeutic delivery to intestinal epithelial cells.

We have made artificial extracellular vesicles like nanoparticles that contain biologically active Agomir (miRNA mimic)/Antagomir (miRNA inhibitor) adsorbed on magnetic ZnO particles bound by a lipid bilayer membrane from Caco-2 cells (human colorectal adenocarcinoma), which we examined for use as therapeutic nanoparticles or as delivery vehicles for therapeutic agents to the gut epithelia. Magnetic ZnO nanoparticles were synthesized using Manganese doping in both solid-state reaction (SSR) and alkaline aqueous solution methods. The SSR method exhibited ferromagnetic behavior, whereas the alkaline solution method yielded a nanorod-like morphology.

Trends in and factors associated with family physician-performed screening colonoscopies in the United States: 2016-2021.

Purpose: Family physician (FP)-performed screening colonoscopies can serve as 1 strategy in the multifaceted strategy necessary to improve national colorectal cancer screening rates, particularly in rural areas where specialist models can fail. However, little research exists on the performance of this strategy in the real world. In this study, we evaluated trends in and factors associated with FP-performed screening colonoscopies in the United States between 2016 and 2021.

Novel role of folate (vitamin B9) released by fermenting bacteria under Human Intestine like environment.

The anaerobic region of the gastrointestinal (GI) tract has been replicated in the anaerobic chamber of a microbial fuel cell (MFC). Electroactive biomolecules released by the facultative anaerobes (Providencia rettgeri) under anoxic conditions have been studied for their potential role for redox balance. MALDI study reveals the presence of vitamin B9 (folate), 6-methylpterin, para-aminobenzoic acid (PABA) and pteroic acid called pterin pool.

First interobserver agreement of optical coherence tomography in the bile duct: A multicenter collaborative study.

 Optical coherence tomography (OCT) is a new technology available for evaluation of indeterminate biliary strictures. It allows under-the-surface visualization and preliminary studies have confirmed standardized characteristics associated with malignancy. The aim of this study is to evaluate the first interobserver agreement in identifying previously agreed upon OCT criteria and diagnosing of malignant versus benign disease.

American Indian/Alaska Native and black colon cancer patients have poorer cause-specific survival based on disease stage and anatomic site of diagnosis.

Objectives: Studies of race-specific colon cancer (CC) survival differences between right- vs. left-sided CC typically focus on Black and White persons and often consider all CC stages as one group. To more completely examine potential racial and ethnic disparities in side- and stage-specific survival, we evaluated 5-year CC cause-specific survival probabilities for five racial/ethnic groups by anatomic site (right or left colon) and stage (local, regional, distant).

Dots, lines, contours, and ends: An image-based review of esophageal pathology.

Esophageal pathologies encountered on fluoroscopic examination may pose a diagnostic challenge to the interpreting Radiologist. Understanding the varied imaging appearances of esophageal pathology requires a thorough understanding of barium esophagography. This article reviews the various fluoroscopic imaging findings of different esophageal pathologies by describing an approach to image interpretation centered on dots, lines, contours, and ends.

Evolving role of artificial intelligence in gastrointestinal endoscopy.

Artificial intelligence (AI) is a combination of different technologies that enable machines to sense, comprehend, and learn with human-like levels of intelligence. AI technology will eventually enhance human capability, provide machines genuine autonomy, and reduce errors, and increase productivity and efficiency. AI seems promising, and the field is full of invention, novel applications; however, the limitation of machine learning suggests a cautious optimism as the right strategy.

Migration of Over-the-scope Clip Resulting in Anal Pain and Obstructed Defecation.

Iatrogenic perforation is a known and feared complication of diagnostic and therapeutic colonoscopy. Specific locations in the gastrointestinal tract, such as the jejunum, have a higher risk of perforation owing to its difficult anatomical position. Over-the-scope clips have recently been used for the management of these perforations.

MicroRNA in Pancreatic Cancer: From Biology to Therapeutic Potential.

Pancreatic cancer is one of the most aggressive malignancies, accounting for more than 45,750 deaths annually in the U.S. alone.

A multicenter evaluation of a new EUS core biopsy needle: Experience in 200 patients.

Background And Objectives: We present a multicenter study of a new endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) needle (Acquire, Boston Scientific, Natick, MA). The aim of the study was to analyze the needle's clinical performance when sampling solid lesions and to assess the safety of this device.

Methods: We performed a multicenter retrospective study of patients undergoing EUS-FNB during July 1-November 15, 2016.

Oesophageal stent placement to treat a massive iatrogenic duodenal defect after laparoscopic cholecystectomy.

Iatrogenic duodenal injury occurring during laparoscopic cholecystectomy (LC) is managed surgically, though rarely a large, persistent fistula is refractory to surgical interventions. We present the case of a 40-year-old woman transferred to our centre following elective LC for a reported perforated duodenal ulcer. An uncontained leak was found to originate from a 1.
