Small bowel disease prevalence on video capsule endoscopy in chronic granulomatous disease-associated inflammatory bowel disease.

BACKGROUND AND AIM: Patients with chronic granulomatous disease (CGD) may develop inflammatory bowel disease (IBD). Characterization of small bowel disease in this cohort is scarce. Here, we sought to determine the prevalence and characteristics of small bowel disease and evaluate the clinical utility of video capsule endoscopy (VCE) for its diagnosis. METHODS: A retrospective study was performed on patients with CGD who were evaluated for gastrointestinal disease with VCE as a part of ongoing natural history studies at a single academic center. VCEs were reviewed for inflammatory findings and severity of disease utilizing the Capsule Endoscopy Crohn's Disease Activity Index. Radiographic studies and endoscopies performed within 30 days of VCE were compared with small bowel inflammatory findings. RESULTS: Twenty-six VCEs corresponding to 25 patients were found. The majority of patients were male and White; mean age was 28 years old. The majority (85%) demonstrated presence of small bowel inflammatory findings on VCE including strictures, ulcers, erosions, and erythema. Duodenal and ileal inflammatory disease on endoscopy did not correlate with disease on VCE. Moderate-severe colonic disease correlated with moderate-severe disease on VCE. Radiography did not correlate with disease on VCE. Prolonged small bowel transit time correlated with moderate-severe small bowel disease. CONCLUSIONS: Small bowel IBD was highly prevalent in this cohort of patients with CGD. Limitations included small sample size. Given that radiology and duodenal/ileal disease did not correlate with VCE findings, VCE-driven investigation of small bowel disease should be considered in patients with CGD-associated IBD, particularly those with colonic disease.

Social Media and Research Publication Activity During Early Stages of the COVID-19 Pandemic: Longitudinal Trend Analysis.

BACKGROUND: The COVID-19 pandemic has highlighted the importance of rapid dissemination of scientific and medical discoveries. Current platforms available for the distribution of scientific and clinical research data and information include preprint repositories and traditional peer-reviewed journals. In recent times, social media has emerged as a helpful platform to share scientific and medical discoveries. OBJECTIVE: This study aimed to comparatively analyze activity on social media (specifically, Twitter) and that related to publications in the form of preprint and peer-reviewed journal articles in the context of COVID-19 and gastroenterology during the early stages of the COVID-19 pandemic. METHODS: COVID-19-related data from Twitter (tweets and user data) and articles published in preprint servers (bioRxiv and medRxiv) as well as in the PubMed database were collected and analyzed during the first 6 months of the pandemic, from December 2019 through May 2020. Global and regional geographic and gastrointestinal organ-specific social media trends were compared to preprint and publication activity. Any relationship between Twitter activity and preprint articles published and that between Twitter activity and PubMed articles published overall, by organ system, and by geographic location were identified using Spearman's rank-order correlation. RESULTS: Over the 6-month period, 73,079 tweets from 44,609 users, 7164 journal publications, and 4702 preprint publications were retrieved. Twitter activity (ie, number of tweets) peaked in March 2020, whereas preprint and publication activity (ie, number of articles published) peaked in April 2020. Overall, strong correlations were identified between trends in Twitter activity and preprint and publication activity (P<.001 for both). COVID-19 data across the three platforms mainly concentrated on pulmonology or critical care, but when analyzing the field of gastroenterology specifically, most tweets pertained to pancreatology, most publications focused on hepatology, and most preprints covered hepatology and luminal gastroenterology. Furthermore, there were significant positive associations between trends in Twitter and publication activity for all gastroenterology topics (luminal gastroenterology: P=.009; hepatology and inflammatory bowel disease: P=.006; gastrointestinal endoscopy: P=.007), except pancreatology (P=.20), suggesting that Twitter activity did not correlate with publication activity for this topic. Finally, Twitter activity was the highest in the United States (7331 tweets), whereas PubMed activity was the highest in China (1768 publications). CONCLUSIONS: The COVID-19 pandemic has highlighted the potential of social media as a vehicle for disseminating scientific information during a public health crisis. Sharing and spreading information on COVID-19 in a timely manner during the pandemic has been paramount; this was achieved at a much faster pace on social media, particularly on Twitter. Future investigation could demonstrate how social media can be used to augment and promote scholarly activity, especially as the world begins to increasingly rely on digital or virtual platforms. Scientists and clinicians should consider the use of social media in augmenting public awareness regarding their scholarly pursuits.

COVID-19: An analysis of social media and research publication activity during the early stages of the pandemic.

Objectives: The COVID-19 pandemic has highlighted the importance of rapid dissemination of scientific and medical discovery. Social media (SoMe) has become an invaluable platform in science and medicine. This study analyzed activity of SoMe (Twitter), preprints, and publications related to COVID-19 and gastroenterology (GI) during the COVID-19 pandemic. Methods: Data from Twitter, preprint servers and PubMed was collected and analyzed from December 2019 through May 2020. Global and regional geographic and gastrointestinal organ specific social media trends were compared to preprint and publication activity; any associations were identified. Results: Over the 6-month period, there were 73,079 tweets from 44,609 users, 7,164 publications, and 4,702 preprints. Twitter activity peaked during March while preprints and publications peaked in April 2020. Strong correlations were identified between Twitter and both preprints and publications activity (p<0.001 for both). While COVID-19 data across the 3 platforms concentrated on pulmonology/critical care, the majority of GI tweets pertained to pancreatology, most publications focused on hepatology, and most preprints covered hepatology and luminal GI (LGI). There were significant associations between Twitter activity and research for all GI subfields (p=0.009 for LGI, p=0.006 for hepatology and IBD, p=0.007 for endoscopy), except pancreatology (p=0.2). Twitter activity was highest in the US (7,331 tweets) whereas PubMed activity was highest in China (1,768 publications). Conclusions: The COVID-19 pandemic has highlighted the utility of SoMe as a vehicle for disseminating scientific information during a public health crisis. Scientists and clinicians should consider the use of SoMe in augmenting public awareness of their scholarly pursuits.

Twitter As a Noninvasive Bio-Marker for Trends in Liver Disease.

With the success of hepatitis C virus (HCV) direct-acting antiviral therapies, there has been a shift in research focus to the other major chronic liver diseases (CLDs). The use of social media, specifically Twitter, has become a popular platform for understanding public health trends and for performing health care research. To evaluate this, we studied the areas of public interest and social media trends of the following three major CLDs: hepatitis B virus (HBV), HCV, and nonalcoholic fatty liver disease (NAFLD)/nonalcoholic steatohepatitis (NASH). Twitter activity data from January 1, 2013, through January 1, 2019, for HBV, HCV, and NAFLD/NASH were collected using the social media analytic tool Symplur Signals (Symplur LLC) software. Content and regression analyses were performed to understand and predict Twitter activity for each of the CLDs. Over the study period, there were 810,980 tweets generating 4,452,939,516 impressions. HCV tweet activity peaked in 2015 at 243,261 tweets, followed by a decline of 52.4% from 2015 to 2016 with a subsequent plateau through 2018. Meanwhile, NAFLD/NASH and HBV tweet activity has continued to increase, with projections that these two CLDs will surpass HCV by the second half of 2023 and 2024, respectively. Treatment and Management was the most popular content category for HCV and NAFLD/NASH, while Prevention was the most popular content category for HBV. Conclusion: Twitter is a useful social media tool to gauge public interest in liver disease over time. The information provided by Twitter can be used to identify gaps in public knowledge or highlight areas of interest that may need further research. Future studies on the use of Twitter in liver disease are warranted.

Atrial Fibrillation in a Patient With an Accessory Pathway.

A 24-year-old man with history of unspecified arrhythmia presented with palpitations and chest pain. Initial electrocardiogram (ECG) revealed irregular tachycardia with varying QRS width: 150 to 200 beats per minute for narrow complexes and 300 beats per minute for wide complexes. Following cardioversion, ECG revealed sinus tachycardia with a preexcitation pattern of positive delta waves in the anterolateral leads and negative delta waves in inferior leads. The patient remained in sinus rhythm and underwent successful ablation of a right posteroseptal accessory pathway. Subsequent ECG showed upright T waves in the leads I, aVL, and V2-6, large inverted T waves in leads III and aVF, and no delta waves. This case serves as an important reminder that atrial fibrillation (AF) in the presence of an accessory pathway may present with confounding ECG features, potentially leading to incorrect diagnoses and treatments that may be life threatening. Despite 10% to 30% prevalence of AF in the presence of an accessory pathway and the relative awareness of Wolff-Parkinson-White syndrome among general internal medicine providers, the clinical recognition of Wolff-Parkinson-White syndrome may be hindered in the presence of preexcited AF.
