Robust Magnetoelectric Backscatter Communication System for Bioelectronic Implants.

Wireless communication technologies for bioelectronic implants enable remote monitoring for diagnosis and adaptive therapeutic intervention without the constraints of wired connections. However, wireless data uplink from millimeter-scale devices deep in the body struggles to achieve low power consumption while maintaining large misalignment tolerances. Here, we report a passive wireless backscatter communication system based on magnetoelectric transducers that consumes less than 0.

The Association Between a Mediterranean Diet and Symptoms of Irritable Bowel Syndrome.

Background & Aims: Low adherence to Mediterranean diet (MD) has been shown to be associated with a higher prevalence of irritable bowel syndrome (IBS), but its association with IBS symptoms is not established. We aim to assess the association between MD and IBS symptoms, identify components of MD associated with IBS symptoms, and determine if a symptom-modified MD is associated with changes in the gut microbiome.

Methods: One hundred and six Rome +IBS and 108 health control participants completed diet history and gastrointestinal symptom questionnaires.

Endoscopy for the diagnosis and treatment of gastrointestinal bleeding caused by malignancy.

Background And Aim: The diagnosis and treatment of gastrointestinal (GI) bleeding secondary to malignancy can be challenging. Endoscopy is the gold standard to diagnose and treat gastrointestinal bleeding but clinical characteristics and outcomes of patients with malignancy-related bleeding are not well understood. This study aims to look at clinical characteristics, endoscopic findings, safety and clinical outcomes of endoscopic interventions for GI malignancy-related bleeding.

Ethnicity Is an Important Consideration in Screening for Gastric Intestinal Metaplasia.

Background: Gastric intestinal metaplasia (GIM) is a precursor to gastric adenocarcinoma, making it an attractive target for early detection by endoscopy. The aim of this study was to determine the prevalence, risk factors, and associated histologic findings of GIM among patients undergoing endoscopy in a diverse US population.

Methods: We conducted a retrospective, cross-sectional study of patients undergoing elective endoscopy with gastric biopsies at 6 academic and community centers in Houston, Texas.

Alcohol use alters the colonic mucosa-associated gut microbiota in humans.

Alcohol misuse is a risk factor for many adverse health outcomes. Alcohol misuse has been associated with an imbalance of gut microbiota in preclinical models and alcoholic diseases. We hypothesized that daily alcohol use would change the community composition and structure of the human colonic gut microbiota.

Gastrointestinal toxic effects in patients with cancer receiving platinum-based therapy.

: Platinum-based therapy (PBT) can be limited by gastrointestinal adverse events, particularly PBT-related colitis and diarrhea (PCD). We studied clinical features, treatments, and outcomes of PCD. : This was a retrospective study of cancer patients who received PBT and colonoscopic evaluation for PCD symptoms from 2009 to 2018.

Clinical characteristics of colitis induced by taxane-based chemotherapy.

Background: Limited data are available concerning the clinical features of toxic gastrointestinal (GI) effects of taxane-based therapy. We describe the clinical, endoscopic and histologic features of taxane-induced colitis.

Methods: This retrospective study included cancer patients who received taxane therapy and underwent colonoscopy for GI symptoms from 2000-2018.

Neutropenic Enterocolitis: Clinical Features and Outcomes.

Background: Patients undergoing chemotherapy are at risk for mucosal injury and neutropenia, which facilitate colonic mucosal invasion by the bowel flora and subsequent neutropenic enterocolitis, which has a poor prognosis.

Objective: This study aimed to assess the clinical features and outcomes of neutropenic enterocolitis in patients at a comprehensive cancer center.

Design: This is a retrospective cohort study.

Clinical Features of Rituximab-associated Gastrointestinal Toxicities.

Background: Rituximab is effective in treating several cancers. Little is known about gastrointestinal adverse events associated with rituximab. We describe the clinical, endoscopic, and histologic features of rituximab-associated colitis (RC) at a tertiary care cancer center.

Patients with Non-Hodgkin's Lymphoma Are at Risk of Adenomatous Colon Polyps.

Background: Patients with non-Hodgkin's lymphoma (NHL) are frequently referred for colonoscopy to evaluate gastrointestinal symptoms during their treatment course. Here, we described the rate of colonic adenomas in patients with NHL.

Methods: This was a retrospective study of patients with NHL who underwent colonoscopy after being diagnosed with NHL between January 2000 and December 2017.

Early introduction of selective immunosuppressive therapy associated with favorable clinical outcomes in patients with immune checkpoint inhibitor-induced colitis.

Background: Current treatment guidelines for immune-mediated colitis (IMC) recommend 4 to 6 weeks of steroids as first-line therapy, followed by selective immunosuppressive therapy (SIT) (infliximab or vedolizumab) in patients who do not respond to steroids. We assessed the effect of early SIT introduction and number of SIT infusions on clinical outcomes.

Methods: We performed a retrospective review of patients with IMC who received SIT at The University of Texas MD Anderson Cancer Center between January and December 2018.

One-year Surgical Outcomes and Costs for Medicaid Versus Non-Medicaid Patients Undergoing Laparoscopic Roux-en-Y Gastric Bypass: A Single-Center Study.

Purpose: To compare 1-year outcomes and costs between severely obese Medicaid and non-Medicaid patients who underwent laparoscopic Roux-en-Y gastric bypass surgery.

Methods: This is a single-institution retrospective review comparing 33 Medicaid patients to 99 randomly selected non-Medicaid patients (1:3 case-control). Ninety-day and 1-year outcomes were extracted from the electronic health record.

Dietary and psych predictors of weight loss after gastric bypass.

Background: Identifying severely obese patients who will succeed after bariatric surgery remains challenging. Although numerous studies have attempted to identify preoperative patient characteristics associated with weight loss, the roles of many dietary and psychological characteristics are unclear. The purpose of this study was to examine preoperative dietary and psychological predictors of successful weight loss after bariatric surgery.
