This trial investigated the activity of ramucirumab, a monoclonal antibody that targets VEGF receptor-2 (VEGFR-2) and inhibits activity of VEGF, in combination with somatostatin analog therapy in patients (pts) with advanced extra-pancreatic NET.

Methods: We conducted a single-arm phase II trial enrolling pts with advanced, progressive extra-pancreatic NET.

Association between insurance type, clinical characteristics, and healthcare use in adults with congenital heart disease.

Introduction: Adults with congenital heart disease (CHD) represent a heterogeneous and growing population with high healthcare utilization. We sought to understand the association between insurance type, healthcare use, and outcomes among adults with CHD in Oregon.

Methods: The Oregon All Payers All Claims database from 2010 to 2017 was queried for adults aged 18-65 in 2014 with ICD-9 or 10 codes consistent with CHD; patient demographics, comorbidities, healthcare use, and disease severity were identified.

Duchenne Muscular Dystrophy in Two Half-Brothers Due to Inherited 306 Kb Inverted Insertion of 10p15.1 into Intron 44 of the Dp427m Transcript of the Gene.

Duchenne muscular dystrophy (DMD) is a rare genetic disorder caused by the absence of a fully functional dystrophin protein in myocytes. In skeletal muscle, the lack of dystrophin ultimately results in muscle wasting and the replacement of myocytes with fatty or fibrous tissues. In the heart, cardiomyocytes eventually fail and cause fatal cardiomyopathy.

Exploring the Frontier: The Human Microbiome's Role in Rare Childhood Neurological Diseases and Epilepsy.

Emerging research into the human microbiome, an intricate ecosystem of microorganisms residing in and on our bodies, reveals that it plays a pivotal role in maintaining our health, highlighting the potential for microbiome-based interventions to prevent, diagnose, treat, and manage a myriad of diseases. The objective of this review is to highlight the importance of microbiome studies in enhancing our understanding of rare genetic epilepsy and related neurological disorders. Studies suggest that the gut microbiome, acting through the gut-brain axis, impacts the development and severity of epileptic conditions in children.

Early nasal microbiota and subsequent respiratory tract infections in infants with cystic fibrosis.

Background: Respiratory tract infections (RTIs) drive lung function decline in children with cystic fibrosis (CF). While the respiratory microbiota is clearly associated with RTI pathogenesis in infants without CF, data on infants with CF is scarce. We compared nasal microbiota development between infants with CF and controls and assessed associations between early-life nasal microbiota, RTIs, and antibiotic treatment in infants with CF.

One RING to rule them all: Mind bomb-1 ccRING3 controls Notch signaling.

In this issue of Structure, Cao et al. use X-ray crystallography, biochemical, and genetic studies to define the key role of the Mind bomb-1 ccRING3 domain in triggering Notch signaling, and they demonstrate that ccRING3-mediated dimerization is a key step in ligand activation.

Cohort profile: Understanding the influence of early life environments and health and social service system contacts over time and across generations through the Western Australian Aboriginal Child Health Survey (WAACHS) Linked Data Study.

Purpose: Despite the volume of accumulating knowledge from prospective Aboriginal cohort studies, longitudinal data describing developmental trajectories in health and well-being is limited. The linkage of child and carer cohorts from a historical cross-sectional survey with longitudinal health-service and social-service administrative data has created a unique and powerful data resource that underpins the Western Australian Aboriginal Child Health Survey (WAACHS) linked data study. This study aims to provide evidence-based information to Aboriginal communities across Western Australia, governments and non-government agencies on the heterogeneous life trajectories of Aboriginal children and families.

Global Lung Function Initiative reference values for multiple breath washout indices.

Background: Multiple breath washout is a lung function test based on tidal breathing that assesses lung volume and ventilation distribution. The aim of this analysis was to use the Global Lung Function Initiative methodology to develop all-age reference equations for the multiple breath washout indices lung clearance index (LCI) and functional residual capacity (FRC).

Methods: Multiple breath washout data from healthy individuals were collated from sites.

Improving well-being among women in neonatology.

Objective: To evaluate the factors that improve professional and personal well-being amongst women in neonatology (WiN).

Study Design: A 30-question survey of multiple choice, rank order, and open-ended questions focused on professional and personal factors that affect the well-being of WiN members. Quantitative and qualitative methods were used to determine leading factors and themes.

Clinical benefits of self-guided mindfulness coach mobile app use for veterans with posttraumatic stress disorder: A pilot randomized control trial.

Objective: Mindfulness training can relieve posttraumatic stress disorder (PTSD) symptoms in military veterans and others but is inconsistently accessible. Self-guided mobile apps could improve access but their acceptability, feasibility, and benefits for veterans with PTSD have not been established. We conducted a pilot randomized trial of Mindfulness Coach (MC), a free, publicly available, trauma-informed mobile app tailored to veterans.

Expanded carrier screening for inherited genetic disease using exome and genome sequencing.

The goal of this study was to assess the feasibility of using exome (ES) and genome sequencing (GS) in guiding preconception genetic screening (PCGS) for couples who are planning to conceive by creating a workflow for identifying risk alleles for autosomal recessive (AR) and X-linked (XL) disorders without the constraints of a predetermined, targeted gene panel. There were several limitations and challenges related to reporting and the technical aspects of ES and GS, which are listed in the discussion. We selected 150 couples from a cohort of families (trios) enrolled in a research protocol where the goal was to define the genetic etiology of disease in an affected child.

Recurrent p.H119Y variant in MAP2K1 expands the phenotypic spectrum of MAP2K1 -related RASopathy.

We report three unrelated individuals with atypical clinical findings for cardio-facio-cutaneous (CFC) syndrome, all of whom have the same novel, heterozygous de novo p.H119Y (c.355 C>T) transition variant in MAP2K1, identified by exome sequencing.

Lung structural and functional impairments in young children with cystic fibrosis diagnosed following newborn screening - A nationwide observational study.

Background: Non-invasive and sensitive clinical endpoints are needed to monitor onset and progression of early lung disease in children with cystic fibrosis (CF). We compared lung clearance index (LCI), FEV, functional and structural lung magnetic resonance imaging (MRI) outcomes in Swiss children with CF diagnosed following newborn screening.

Methods: Lung function (LCI, FEV) and unsedated functional and structural lung MRI was performed in 79 clinically stable children with CF (3 - 8 years) and 75 age-matched healthy controls.

Impacts of phosphorus amendments on legacy soil contamination from lead-based paint on a California, USA university campus.

Lead (Pb) is one of the most common heavy metal urban soil contaminants with well-known toxicity to humans. This incubation study (2-159 d) compared the ability of bone meal (BM), potassium hydrogen phosphate (KP), and triple superphosphate (TSP), at phosphorus:lead (P:Pb) molar ratios of 7.5:1, 15:1, and 22.

The dynamic hypoosmotic response of relies on the mechanosensitive channel MscS.

adapts to osmotic down-shifts by releasing metabolites through two mechanosensitive (MS) channels, low-threshold MscS and high-threshold MscL. To investigate each channel's contribution to the osmotic response, we generated , , and double mutants in O395. We characterized their tension-dependent activation in patch-clamp, and the millisecond-scale osmolyte release kinetics using a stopped-flow light scattering technique.

Snyder-Robinson syndrome presenting with learning disability, epilepsy, and osteoporosis: a novel gene variant.

Snyder-Robinson syndrome (SRS) is a rare X-linked recessive disorder characterized by a collection of clinical features including mild to severe intellectual disability, hypertonia, marfanoid habitus, facial asymmetry, osteoporosis, developmental delay and seizures.

FGF12 copy number variant associated with epileptic encephalopathy.

FGF12 related epilepsy presents with variable phenotypes. We report another patient with a duplication involving the FGF12 gene who presented similar to other published cases having normal early development and responded to phenytoin.

Protective anti-chlamydial vaccine regimen-induced CD4+ T cell response mediates early inhibition of pathogenic CD8+ T cell response following genital challenge.

We have demonstrated previously that TNF-α-producing CD8+ T cells mediate chlamydial pathogenesis, likely in an antigen (Ag)-specific fashion. Here we hypothesize that inhibition of Ag-specific CD8+ T cell response after immunization and/or challenge would correlate with protection against oviduct pathology induced by a protective vaccine regimen. Intranasal (i.

Unraveling paralog-specific Notch signaling through thermodynamics of ternary complex formation and transcriptional activation of chimeric receptors.

Notch signaling in humans is mediated by four paralogous receptors that share conserved architectures and possess overlapping, yet non-redundant functions. The receptors share a canonical activation pathway wherein upon extracellular ligand binding, the Notch intracellular domain (NICD) is cleaved from the membrane and translocates to the nucleus where its N-terminal RBP-j-associated molecule (RAM) region and ankyrin repeat (ANK) domain bind transcription factor CSL and recruit co-activator Mastermind-like-1 (MAML1) to activate transcription. However, different paralogs can lead to distinct outcomes.
