BACKGROUND/AIMS: Patients with gastroparesis often have biliary/pancreatic and small bowel symptoms but the effects of gastric electrical stimulation on small bowel electrical activity of the mid-gut have not been studied. Animal model aim: Establish gastric and upper small bowel/biliary slow wave activity relationships with electrical stimulation. Human study aim: Demonstrate improvement in symptoms associated with proximal small bowel dysmotility in gastric stimulated patients. MATERIALS AND METHODS: Animal model: In vivo evoked responses of duodenal and Sphincter of Oddi measures recorded during gastric electrical stimulation in a nonsurvival swine model (N = 3)...

Royal jelly is the queen-maker for the honey bee Apis mellifera, and has cross-species effects on longevity, fertility, and regeneration in mammals. Despite this knowledge, how royal jelly or its components exert their myriad effects has remained poorly understood. Using mouse embryonic stem cells as a platform, here we report that through its major protein component Royalactin, royal jelly can maintain pluripotency by activating a ground-state pluripotency-like gene network. We further identify Regina, a mammalian structural analog of Royalactin that also induces a naive-like state in mouse embryonic stem cells...

CONTEXT: The role of cytoreductive nephrectomy (CN) in the management of metastatic renal cell carcinoma (mRCC) in the targeted therapy (TT) era is controversial. OBJECTIVE: To assess if CN versus no CN is associated with improved overall survival (OS) in patients with mRCC treated in the TT era and beyond, characterize the morbidity of CN, identify prognostic and predictive factors, and evaluate outcomes following treatment sequencing. EVIDENCE ACQUISITION: Medline, EMBASE, and Cochrane databases were searched from inception to June 4, 2018 for English-language clinical trials, cohort studies, and case-control studies evaluating patients with mRCC who underwent and those who did not undergo CN...

BACKGROUND AND AIMS: Induction of cross-reactive antibodies targeting conserved epitopes of the envelope proteins E1E2 is a key requirement for an HCV vaccine. Conserved epitopes like the viral CD81-binding site are targeted by rare broadly neutralizing antibodies. However, these viral segments are occluded by variable regions and glycans. We aimed to identify antigens exposing conserved epitopes and to characterize their immunogenicity. METHODS: We created HCV variants with mutated glycosylation sites and/or hypervariable region 1 (HVR1)...

Most of the planet's diversity is concentrated in the tropics, which includes many regions undergoing rapid climate change. Yet, while climate-induced biodiversity changes are widely documented elsewhere, few studies have addressed this issue for lowland tropical ecosystems. Here we investigate whether the floristic and functional composition of intact lowland Amazonian forests have been changing by evaluating records from 106 long-term inventory plots spanning 30 years. We analyse three traits that have been hypothesized to respond to different environmental drivers (increase in moisture stress and atmospheric CO2 concentrations): maximum tree size, biogeographic water-deficit affiliation and wood density...

BACKGROUND & AIMS: Gastroparesis is a chronic disorder of the stomach characterized by nausea, vomiting, early satiety, postprandial fullness, and abdominal pain. There is limited information on gastroparesis in minority populations. We assessed ethnic, racial, and sex variations in the etiology, symptoms, quality of life, gastric emptying, treatments, and symptom outcomes of patients with gastroparesis. METHODS: We collected information from the National Institutes of Health Gastroparesis Consortium on 718 adult patients, from September 2007 through December 2017...

Patients with gastroparesis sometimes suffer from intractable nausea and vomiting, abdominal pain, and bloating, as well as a host of other symptoms that can often be difficult to control. Initially, patients are treated conservatively; some do well with conservative management but unfortunately some do not. Over the years, studies have shown the benefits of gastric electrical stimulation, which often results in symptomatic improvement and improvement in gastric emptying times. This article discusses the history of gastric electrical stimulation and its use in clinical practice to help those suffering from gastroparesis that is refractory to conservative medical management...

Background: Gastric electrical stimulation (GES) is used in both the US and Europe, but little research has investigated the demographics of gastroparesis patients receiving GES by geographic location. Methods: We compared data from 380 patients, 296 female and 84 males, mean age 42 years, 246 idiopathic (ID), 107 diabetic (DM), and 27 post-surgical (PS). The statistical significance was calculated by Chi-square test and a P-value obtained for ID, DM, and PS. The statistical significance was calculated by Fischer exact test and a P-value obtained comparing male vs...

BACKGROUND: Inflammatory bowel disease (IBD) can have autoimmunity and/or intestinal barrier dysfunction as part of pathophysiology and may be refractory to all available treatment options. Serum-derived bovine immunoglobulin (SBI) binds microbial components with postulated downstream effects of normalized gut immune and barrier function, which may be useful for managing IBD. The purpose of our study was to evaluate the effectiveness of SBI in the management of refractory IBD, particularly symptoms of chronic diarrhea and loose stools...

Stopping interventions is a critical decision for parasite elimination programmes. Quantifying the probability that elimination has occurred due to interventions can be facilitated by combining infection status information from parasitological surveys with extinction thresholds predicted by parasite transmission models. Here we demonstrate how the integrated use of these two pieces of information derived from infection monitoring data can be used to develop an analytic framework for guiding the making of defensible decisions to stop interventions...

BACKGROUND & AIMS: Many patients with gastroparesis are prescribed opioids for pain control, but indications for opioid prescription and relations of opioid use to gastroparesis manifestations are undefined. We characterized associations of use of potent vs weaker opioids and presentations of diabetic and idiopathic gastroparesis. METHODS: We collected data on symptoms, gastric emptying, quality of life, and healthcare resource use from 583 patients with gastroparesis (more than 10% 4 hr scintigraphic retention) from the NIDDK Gastroparesis Consortium, from January 2007 through November 2016...

Purpose: Referral access to subspecialty care for patients with gastrointestinal (GI) diseases is not well defined, but has significant importance to patients. We hypothesized that patients experience barriers to care in two common gastroenterology subspecialties, Hepatology and Motility, in a university medical center. Methods: Two hundred thirteen clinic patients (mean age 46.5 years; 66.5% female; 85.6% Caucasians) completed a formatted questionnaire on access to care. Hepatology patients were older (49...

We present a study of multiple sclerosis segmentation algorithms conducted at the international MICCAI 2016 challenge. This challenge was operated using a new open-science computing infrastructure. This allowed for the automatic and independent evaluation of a large range of algorithms in a fair and completely automatic manner. This computing infrastructure was used to evaluate thirteen methods of MS lesions segmentation, exploring a broad range of state-of-theart algorithms, against a high-quality database of 53 MS cases coming from four centers following a common definition of the acquisition protocol...

The therapeutic effect of targeted kinase inhibitors can be significantly reduced by intrinsic or acquired resistance mutations that modulate the affinity of the drug for the kinase. In cancer, the majority of missense mutations are rare, making it difficult to predict their impact on inhibitor affinity. This complicates the practice of precision medicine, pairing of patients with clinical trials, and development of next-generation inhibitors. Here, we examine the potential for alchemical free-energy calculations to predict how kinase mutations modulate inhibitor affinities to Abl, a major target in chronic myelogenous leukemia (CML)...

BACKGROUND: Older patients (≥60 years) with acute myeloid leukemia (AML) face difficult decisions regarding treatment with "intensive" chemotherapy that carries significant toxicity for a small chance of a cure versus "nonintensive" chemotherapy to control the disease, but with fewer side effects. However, studies of how these patients understand the risks and benefits of such treatments are lacking. METHODS: We conducted a longitudinal study of older patients newly diagnosed with AML assessing patients' ( n = 100) and oncologists' ( n = 11) perceptions of treatment-related mortality at enrollment and prognosis at 1 month...
