Effectiveness of electronic medical record-based strategies for death and hospital admission endpoint capture in pragmatic clinical trials.

Objective: Event capture in clinical trials is resource-intensive, and electronic medical records (EMRs) offer a potential solution. This study develops algorithms for EMR-based death and hospitalization capture and compares them with traditional event capture methods.

Materials And Methods: We compared the effectiveness of EMR-based event capture and site-captured events adjudicated by a clinical endpoint committee in the multi-center INfluenza Vaccine to Effectively Stop cardio Thoracic Events and Decompensated heart failure (INVESTED) trial for participants from the Veterans Affairs healthcare system.

Environmental toxicants modulate disease severity in pediatric metabolic dysfunction-associated steatohepatitis.

Objectives: Metabolic dysfunction-associated steatotic liver disease (MASLD) is common in children. We hypothesized environmental toxins could drive progression to metabolic dysfunction-associated steatohepatitis (MASH), and assayed serum toxins and metabolites in children with histologically characterized MASLD/MASH.

Methods: Environmental chemicals, common in household items, perfluoroalkyl substances (PFAS), polybrominated flame retardants (polybrominated diphenyl ethers [PBDEs]), and metabolic profiles were assayed in children enrolled in the multicenter NASH Clinical Research Network Pediatric Database 2.

Physician workload and practice management in pediatric gastroenterology.

Objectives: The pediatric gastroenterology workforce has grown in the last few decades. The North American Society of Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) formed a task force to understand current pediatric gastroenterology organizations' practice structures.

Methods: 19-item electronic survey was distributed to NASPGHAN members who were clinical or academic division directors.

Sofosbuvir-velpatasvir in children 3-17 years old with hepatitis C virus infection.

Background: The safety and efficacy of sofosbuvir-velpatasvir in children aged 3-17 years with chronic hepatitis C virus (HCV) infection of any genotype were evaluated.

Methods: In this Phase 2, multicenter, open-label study, patients received once daily for 12 weeks either sofosbuvir-velpatasvir 400/100 mg tablet (12-17 years), 200/50 mg low dose tablet or oral granules (3-11 years and ≥17 kg), or 150/37.5 mg oral granules (3-5 years and <17 kg).

Building Research Infrastructure to Develop Greater Learning Efficiencies (BRIDGE).

In this manuscript, we outline our developed version of a Learning Health System (LHS) in oncology implemented at the Department of Veterans Affairs (VA). Transferring healthcare into an LHS framework has been one of the spearpoints of VA's Central Office and given the general lack of evidence generated through randomized control clinical trials to guide medical decisions in oncology, this domain is one of the most suitable for this change. We describe our technical solution, which includes a large real-world data repository, a data science and algorithm development framework, and the mechanism by which results are brought back to the clinic and to the patient.

Change in Health-Related Quality of Life in Youth with Chronic Hepatitis B Living in North America: A 5-Year Cohort Study.

Background: Greater hepatitis-related symptomology is associated with lower health-related quality-of-life (HRQoL) among untreated youth with chronic hepatitis B (CHB). How HRQoL changes over time in this population is unknown.

Methods: Children from 7 hepatology centers in North America positive for hepatitis B surface antigen, not taking anti-viral therapy, were enrolled in the Hepatitis B Research Network.

Physician Burnout in Pediatric Gastroenterology.

Objectives: Physicians are prone to burnout which can negatively affect the quality of patient care and lead to medical errors. Burnout can also affect physicians by impacting their personal relationships, their sense of career fulfillment, and job satisfaction. The North American Society of Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) formed a taskforce to investigate burnout among pediatric gastroenterologists.

Health-related Quality of Life in a Prospective Study of Ultrasound to Detect Cystic Fibrosis-related Liver Disease in Children.

Objectives: Cystic fibrosis liver disease (CFLD) begins early in life. Symptoms may be vague, mild, or nonexistent. Progressive liver injury may be associated with decrements in patient health before liver disease is clinically apparent.

Serum biomarkers correlated with liver stiffness assessed in a multicenter study of pediatric cholestatic liver disease.

Background And Aims: Detailed investigation of the biological pathways leading to hepatic fibrosis and identification of liver fibrosis biomarkers may facilitate early interventions for pediatric cholestasis.

Approach And Results: A targeted enzyme-linked immunosorbent assay-based panel of nine biomarkers (lysyl oxidase, tissue inhibitor matrix metalloproteinase (MMP) 1, connective tissue growth factor [CTGF], IL-8, endoglin, periostin, Mac-2-binding protein, MMP-3, and MMP-7) was examined in children with biliary atresia (BA; n = 187), alpha-1 antitrypsin deficiency (A1AT; n = 78), and Alagille syndrome (ALGS; n = 65) and correlated with liver stiffness (LSM) and biochemical measures of liver disease. Median age and LSM were 9 years and 9.

Long-term follow-up and liver outcomes in children with cystic fibrosis and nodular liver on ultrasound in a multi-center study.

Background: Nodular liver (NOD) in cystic fibrosis (CF) suggests advanced CF liver disease (aCFLD); little is known about progression of liver disease (LD) after detection of sonographic NOD.

Methods: Clinical, laboratory, and ultrasound (US) data from Prediction by Ultrasound of the Risk of Hepatic Cirrhosis in CFLD Study participants with NOD at screening or follow-up were compared with normal (NL). Linear mixed effects models were used for risk factors for LD progression and Kaplan-Meier estimator for time-to-event.

Risk of variceal hemorrhage and pretransplant mortality in children with biliary atresia.

Background And Aims: The natural history of gastroesophageal variceal hemorrhage (VH) in biliary atresia (BA) is not well characterized. We analyzed risk factors, incidence, and outcomes of VH in a longitudinal multicenter study.

Approach And Results: Participants enrolled in either an incident (Prospective Database of Infants with Cholestasis [PROBE]) or prevalent (Biliary Atresia Study of Infants and Children [BASIC]) cohort of BA were included.

Impact of progressive familial intrahepatic cholestasis on caregivers: caregiver-reported outcomes from the multinational PICTURE study.

Background: Progressive familial intrahepatic cholestasis (PFIC) is a spectrum of rare genetic diseases characterized by inadequate bile secretion that requires substantial ongoing care, though little research is published in this area. We report health-related quality of life (HRQoL) and work productivity outcomes from the retrospective, cross-sectional PICTURE study investigating the burden of PFIC on caregivers. Information from caregivers of patients with PFIC 1 or 2 in Germany, the United Kingdom and the United States from September 2020 to March 2021 was included.

Targeted Mass Spectrometry Enables Multiplexed Quantification of Immunomodulatory Proteins in Clinical Biospecimens.

Immunotherapies are revolutionizing cancer care, producing durable responses and potentially cures in a subset of patients. However, response rates are low for most tumors, grade 3/4 toxicities are not uncommon, and our current understanding of tumor immunobiology is incomplete. While hundreds of immunomodulatory proteins in the tumor microenvironment shape the anti-tumor response, few of them can be reliably quantified.

Hepatitis C: Current State of Treatment in Children.

Hepatitis C in children is on the rise due to perinatal transmission from infected mothers, and high-risk practices in adolescents and young adults. Prevalence remains underestimated because children at high risk are often not screened. Treatment has evolved over the past decade with the advent of new drugs, and global elimination is now possible.

Association Between Transient Elastography and Controlled Attenuated Parameter and Liver Ultrasound in Children With Cystic Fibrosis.

Methods to identify children with cystic fibrosis (CF) at risk for development of advanced liver disease are lacking. We aim to determine the association between liver stiffness measurement (LSM) by vibration-controlled transient elastography (VCTE) with research ultrasound (US) patterns and conventional hepatic markers as a potential means to follow liver disease progression in children with CF. ELASTIC (Longitudinal Assessment of Transient Elastography in CF) is a nested cohort of 141 patients, ages 7-21, enrolled in the Prediction by US of Risk of Hepatic Cirrhosis in CF (PUSH) Study.

The distinct concerns of LGBTQ+ people when accessing midwifery care and support is an issue requiring a specific focus to ensure needs are met effectively.

Aim: The aim of this systematic review was to critically appraise and synthesise the best available evidence regarding the views and experiences of LGBTQ+ people in relation to midwifery care and supports.

Presentation and Outcomes of Infants With Idiopathic Cholestasis: A Multicenter Prospective Study.

Objectives: The aim of the study was to determine the frequency and natural history of infantile idiopathic cholestasis (IC) in a large, prospective, multicenter cohort of infants.

Methods: We studied 94 cholestatic infants enrolled up to 6 months of age in the NIDDK ChiLDReN (Childhood Liver Disease Research Network) "PROBE" protocol with a final diagnosis of IC; they were followed up to 30 months of age.

Results: Male sex (66/94; 70%), preterm birth (22/90 with data; 24% born at < 37 weeks' gestational age), and low birth weight (25/89; 28% born at <2500 g) were frequent, with no significant differences between outcomes.

The Inflammatory Cytokine Profile Associated With Liver Damage Is Broader and Stronger in Patients With Chronic Hepatitis B Compared to Patients With Acute Hepatitis B.

Liver damage in hepatitis B is immune driven and correlates with inflammatory markers in patient serum. There is no comparison of these markers to determine if inflammatory profiles are distinct to different types of liver damage across patients at different stages of disease. We measured 25 inflammatory markers in patients with acute hepatitis B and chronic hepatitis B with hepatitis B e antigen seroconversion and chronic patients stopping nucleoside analogue therapy.

Chronic Hepatitis Is Common and Often Untreated Among Children with Hepatitis B Infection in the United States and Canada.

Objective: To determine the outcomes of chronic hepatitis B virus (HBV) infection in a large, prospectively studied cohort of children in the US and Canada.

Study Design: This was a prospective, observational study of children with chronic HBV enrolled in 7 clinical centers and evaluated at baseline, weeks 24 and 48, and annually thereafter, with analysis of demographic, clinical, physical examination, and blood test data.

Results: Among 362 children followed for a median of 4.

Hepatitis B virus genome diversity in adolescents: Tenofovir disoproxil fumarate treatment effect and HBeAg serocon version.

More systematic analysis of hepatitis B virus (HBV) genome diversity, linked with tenofovir disoproxil fumarate (TDF) treatment and HBeAg seroconversion, are needed. GS-US-174-0115 was a double-blind, placebo-controlled, Phase 3, 192-week clinical trial that evaluated TDF in adolescents with chronic hepatitis B (CHB). HBV full-genome deep sequencing was performed using Illumina MiSeq at baseline (BL; n = 85), Week 8 (W8; n = 80), Week 72 (W72; PBO only, n = 42), and treatment-free follow-up (TDF only, n = 25).

Highly multiplexed 2-dimensional imaging mass cytometry analysis of HBV-infected liver.

Studies of human hepatitis B virus (HBV) immune pathogenesis are hampered by limited access to liver tissues and technologies for detailed analyses. Here, utilizing imaging mass cytometry (IMC) to simultaneously detect 30 immune, viral, and structural markers in liver biopsies from patients with hepatitis B e antigen+ (HBeAg+) chronic hepatitis B, we provide potentially novel comprehensive visualization, quantitation, and phenotypic characterizations of hepatic adaptive and innate immune subsets that correlated with hepatocellular injury, histological fibrosis, and age. We further show marked correlations between adaptive and innate immune cell frequencies and phenotype, highlighting complex immune interactions within the hepatic microenvironment with relevance to HBV pathogenesis.

Burden of illness of progressive familial intrahepatic cholestasis in the US, UK, France, and Germany: study rationale and protocol of the PICTURE study.

: Progressive familial intrahepatic cholestasis (PFIC) is an ultra-rare disease with a considerable burden on pediatric patients and their caregivers, impacting quality of life (QoL). The mortality rates highlight a significant need for efficacious treatments. Real-world data on associated costs and QoL are needed to gauge the potential impact of new pharmacological treatments.

Outcomes of Childhood Cholestasis in Alagille Syndrome: Results of a Multicenter Observational Study.

Alagille syndrome (ALGS) is an autosomal dominant multisystem disorder with cholestasis as a defining clinical feature. We sought to characterize hepatic outcomes in a molecularly defined cohort of children with ALGS-related cholestasis. Two hundred and ninety-three participants with ALGS with native liver were enrolled.
