Liver Biopsy in Pregnancy: Two Case Reports and Review of the Literature.
No full textThe etiology of most cases of liver diseases in pregnancy can be diagnosed with a thorough history, physical examination, laboratory values, serology, and noninvasive imaging. However, atypical clinical and laboratory presentations of liver diseases/chemistries require a liver biopsy to render an accurate diagnosis in cases where the biopsy results affect the timing of delivery or impact choice of medical therapy. According to the American College of Gastroenterology, liver biopsy can be effectively and safely conducted in pregnant women. Conventional routes of performing a liver biopsy include the percutaneous, transjugular route, and surgical methods. Endoscopic ultrasound-guided liver biopsy is a recent technique that has not yet gained widespread adoption but can potentially serve as an alternative route for obtaining the liver sample. Adverse events associated with liver biopsy include abdominal pain and hemorrhage. Maternal and fetal outcomes are limited to increased risk of preterm birth and small for gestational age neonate. However, very few studies have formally evaluated the safety of liver biopsy in pregnant women. In this review, we present two successful cases of liver biopsy performed during pregnancy and summarize the most recent evidence regarding the safety and outcomes of the procedure in pregnancy to assist clinicians in their decision to perform a liver biopsy during pregnancy or postpone it until after delivery
The Evolution of Device-Assisted Enteroscopy: From Sonde Enteroscopy to Motorized Spiral Enteroscopy
No full textTHIS ARTICLE IS PART OF THE RESEARCH TOPIC: Recent Updates in Advanced Gastrointestinal Endoscopy
The introduction of capsule endoscopy in 2001 opened the last “black box” of the gastrointestinal tract enabling complete visualization of the small bowel. Since then, numerous new developments in the field of deep enteroscopy have emerged expanding the diagnostic and therapeutic armamentarium against small bowel diseases. The ability to achieve total enteroscopy and visualize the entire small bowel remains the holy grail in enteroscopy. Our journey in the small bowel started historically with sonde type enteroscopy and ropeway enteroscopy. Currently, double-balloon enteroscopy, single-balloon enteroscopy, and spiral enteroscopy are available in clinical practice. Recently, a novel motorized enteroscope has been described with the potential to shorten procedure time and allow for total enteroscopy in one session. In this review, we will present an overview of the currently available techniques, indications, diagnostic yield, and complications of device-assisted enteroscopy

Intravenous Smart Pumps During Actual Clinical Use: A Descriptive Comparison of Primary and Secondary Infusion Practices.
No full textThis descriptive observational study was conducted to increase understanding of medication administration practices during actual clinical use between 2 commonly used, different types of intravenous (IV) smart pumps. Compliance with manufacturer-recommended setup requirements for both primary and secondary infusions and secondary medication administration delay was compared between a head-height differential system and a cassette system. A total of 301 medication administration observations were included in this study: 102 (34%) for the linear peristaltic IV smart pump (medical-surgical: N = 51; critical care: N = 51) and 199 (66%) for the cassette pump (medical-surgical: N = 88; critical care: N = 111). Results found a 0% compliance for primary line setup and 84% compliance for secondary line setup and 1 omitted medication due to a closed clamp with the linear peristaltic system. For the cassette system, there are no head-height requirements. Two roller clamps were found to be in the closed position on initiation of the secondary infusion, but the clinician was alerted by an alarm, so no medication delays occurred. These findings support that the current system requirements for flow rate accuracy using head-height differential systems are difficult to achieve consistently at the point of care. There is a need for additional human factor designed technology to replace manual actions to improve the process of care for nurses and the safety of care for patients
KEYNOTE-799: Phase 2 trial of pembrolizumab plus platinum chemotherapy and radiotherapy for unresectable, locally advanced, stage 3 NSCLC.
No full textMeeting Abstract: 2021 ASCO Annual Meeting
Background: KEYNOTE-799 (NCT03631784) is an ongoing study of the anti‒PD-1 antibody pembrolizumab (pembro) plus concurrent chemoradiation therapy (cCRT) in patients (pts) with unresectable, locally advanced stage III NSCLC. Prior results from this study in a subset of pts (primary efficacy population) showed an ORR of 69.6% in cohort A (squamous and nonsquamous, n = 112) and 70.5% in cohort B (nonsquamous, n = 61), and grade ≥3 pneumonitis in 8.0% and 7.9% of pts, respectively. Here, we present results for all pts enrolled in KEYNOTE-799.
Methods: This nonrandomized, multisite, open-label phase 2 trial enrolled pts aged ≥18 y with previously untreated, unresectable, pathologically confirmed, stage IIIA‒C NSCLC with measurable disease per RECIST v1.1. Pts in cohort A (squamous and nonsquamous) received 1 cycle of carboplatin AUC 6 and paclitaxel 200 mg/m2 and pembro 200 mg. After 3 wks, pts received carboplatin AUC 2 and paclitaxel 45 mg/m2 QW for 6 wks and 2 cycles of pembro 200 mg Q3W plus standard thoracic radiotherapy (TRT). Pts in cohort B (nonsquamous only) received 3 cycles of cisplatin 75 mg/m2, pemetrexed 500 mg/m2,and pembro 200 mg Q3W, and TRT in cycles 2 and 3. All pts received an additional 14 cycles of pembro 200 mg Q3W. Primary endpoints were ORR per RECIST v1.1 by blinded independent central review (BICR) and the incidence of grade ≥3 pneumonitis (per NCI CTCAE v4.0). Efficacy and safety were assessed in all pts as-treated.
Results: Of 216 pts enrolled in KEYNOTE-799 (cohort A, n = 112; cohort B, n = 104), 112 in cohort A and 102 in cohort B received treatment. As of October 28, 2020, the median (range) time from first dose to database cutoff was 18.5 (13.6–23.8) mo in cohort A and 13.7 (2.9–23.5) mo in cohort B. ORR (95% CI) was 70.5% (61.2%‒78.8%) in cohort A and 70.6% (60.7%‒79.2%) in cohort B. Median DOR was not reached in either cohort (Table). ORR was similar regardless of PD-L1 status ([TPS \u3c1% and TPS ≥1%]; Cohort A, 66.7% and 75.8%; Cohort B, 71.4% and 72.5%) and tumor histology (Cohort A, squamous, 71.2% and nonsquamous, 69.2%). Grade ≥3 pneumonitis occurred in 9 pts (8.0%) in cohort A and 7 (6.9%) in cohort B. Grade 3‒5 treatment-related AEs occurred in 72 pts (64.3%) in cohort A and 51 (50.0%) in cohort B.
Conclusions: Pembro plus cCRT continues to demonstrate promising antitumor activity, regardless of PD-L1 TPS and tumor histology, and manageable safety in pts with previously untreated, locally advanced, stage III NSCLC with longer follow-up. Clinical trial information: NCT03631784

No full textFanconi Syndrome Leading to Hypophosphatemic Osteomalacia Related to Tenofovir Use.
No full textTenofovir disoproxil fumarate (TDF) is used worldwide to treat and prevent Human Immunodeficiency Virus (HIV) infection. Fanconi syndrome is a complication of TDF use and is characterized by inadequate reabsorption of glucose, phosphate and protein in the proximal tubule of the kidney which may eventually lead to osteomalacia manifested by symptoms of pain, muscular weakness and difficulty ambulating. We present a patient with severe osteomalacia due to progressive and unrecognized Fanconi\u27s syndrome, who responded rapidly to TDF withdrawal, oral phosphate repletion and calcitriol. With the widespread use of TDF-containing antiviral regimens, it is critically important that physicians adhere to screening recommendations to detect early Fanconi syndrome, and recognize symptoms of osteomalacia as a serious complication
Direct-acting oral anticoagulants versus warfarin in relation to risk of gastrointestinal bleeding: a systematic review and meta-analysis of randomized controlled trials.
No full textBackground: Direct-acting oral anticoagulants (DOACs) are increasingly used, with studies showing a lower risk of gastrointestinal bleeding (GIB), but overall data for GIB risk remains debatable. The objective was to assess non-fatal and fatal GIB risk in patients on DOACs compared with warfarin from randomized clinical trials (RCTs).
Methods: RCTs comparing warfarin and DOACs for various indications (atrial fibrillation, thromboembolism, insertion of mechanical heart valves) were included. The primary endpoint was any GIB event. Other clinical events, such as fatal GIB, and effects of age (≤60 years or older), time in therapeutic range for warfarin, and choice of individual DOACs on GIB risk, were also assessed.
Results: 14 RCTs were included, comprising 87,407 participants (DOACs n=46,223, warfarin control n=41,184). The risk of GIB with DOACs was similar to that of warfarin (relative risk [RR] 1.04, 95% confidence interval [CI] 0.85-1.27). Compared with warfarin, rivaroxaban (RR 1.23, 95%CI 1.03-1.48) and dabigatran (RR 1.38, 95%CI 1.12-1.71) had a higher risk of any GIB, whereas fatal GIB risk was lower in the DOACs group (RR 0.36, 95%CI 0.15-0.82). The risk of DOAC-related fatal GIB was lower in patients aged ≤60 years and in those with poor coagulation control (RR 0.39, 95%CI 0.15-0.98).
Conclusions: DOACs compared with warfarin have a lower risk of fatal GIB, especially in those agedHowever, the risk of GIB was comparable with warfarin and DOACs, except for rivaroxaban and dabigatran
Comparison of Biliary Drainage Techniques for Malignant Biliary Obstruction: A Systematic Review and Network Meta-analysis.
No full textBACKGROUND AND AIMS: Endoscopic retrograde cholangiopancreatography (ERCP), percutaneous transhepatic biliary drainage, and endoscopic ultrasound (EUS)-guided biliary drainage are all established techniques for drainage of malignant biliary obstruction. This network meta-analysis (NMA) was aimed at comparing all 3 modalities to each other.
MATERIALS AND METHODS: Multiple databases were searched from inception to October 2019 to identify relevant studies. All the patients were eligible to receive any one of the 3 interventions. Data extraction and risk of bias assessment was performed using standardized tools. Outcomes of interest were technical success, clinical success, adverse events, and reintervention. Direct meta-analyses were performed using the random-effects model. NMA was conducted using a multivariate, consistency model with random-effects meta-regression. The GRADE approach was followed to rate the certainty of evidence.
RESULTS: The final analysis included 17 studies with 1566 patients. Direct meta-analysis suggested that EUS-guided biliary drainage had a lower reintervention rate than ERCP. NMA did not show statistically significant differences to favor any one intervention with certainty across all the outcomes. The overall certainty of evidence was found to be low to very low for all the outcomes.
CONCLUSIONS: The available evidence did not favor any intervention for drainage of malignant biliary obstruction across all the outcomes assessed. ERCP with or without EUS should be considered first to allow simultaneous tissue acquisition and biliary drainage
Reduced Incidence of New Gastrointestinal Cancers Diagnosis During COVID-19 Pandemic
No full textIntroduction- Gastrointestinal cancers such as esophageal, gastric, colon, liver, and pancreas cancers present a significant global challenge. The burden of these cancers depends mainly on early recognition and treatment initiation. COVID-19 pandemic led to a strain on multiple healthcare systems resulting in stay-at-home restraints, which might have impacted early recognition of these cancers. The data about the the incidence of GI cancers during the pandemic is scarce.
Methods- All adult patients with a new diagnosis of GI cancers in 2020 were compared with the patients in 2019. ICD-10 codes were utilized to identify these patient from TriNetX, a federated cloud-based network that comprises 92 healthcare organizations across the US. The primary outcome of the study was rates of GI cancer diagnoses. The secondary outcomes were GI endoscopy (EGD/sigmoidoscopy/colonoscopy) utilization, rates of endoscopic ultrasound (EUS), and endoscopic retrograde cholangiopancreatography (ERCP), rates of CT/MRI imaging, and overall mortality. The outcomes were measured after 1:1 propensity matching of the groups based on the baseline demographics and comorbidities.
Results- A total of 166,302 patients were diagnosed with GI cancers (colon cancer followed by pancreas, liver, stomach, esophagus in descending order) in 2020 compared to 403,424 patients in 2019. There was a reduction of 41.2% in the diagnosis of new GI cancers in 2020. Comorbidities of these patients at presentation and clinical outcomes are noted in Table 1. After matching, rates of endoscopy utilization (risk ratio [RR]- 0.70 (CI- 0.67 – 0.74)), EUS/ERCP (RR 0.58 (CI:0.52–0.64)), CT/MRI (RR 0.95 (CI:0.90–1.00)) were lower in 2020 compared to 2019 group. 30-day all-cause mortality was also lower in 2020 group (RR 0.82 (CI- 0.79 – 0.86)).
Discussion- The rates of new GI cancers incidence decreased by 41.2% during 2020 compared to 2019. Moreover, endoscopy utilization was reduced by 30-42% during the pandemic. This signifies a major public health burden with a potential increase in the number of patients with late-stage cancers, adversely affecting their survival. These findings are probably related to reduced endoscopy rates utilized for cancer screening. Therefore, there is an urgent need to increase the GI endoscopy utilization and non-invasive tools to close the screening gap that occurred during the pandemic. Policy changes and stakeholders should pursue a consensus approach in developing mass screening strategies to meet the need
