Functional validation of a novel STAT3 'variant of unknown significance' identifies a new case of STAT3 GOF Syndrome and reveals broad immune cell defects.

Introduction: STAT3 orchestrates crucial immune responses through its pleiotropic functions as a transcription factor. Patients with germline monoallelic dominant negative or hypermorphic STAT3 variants, who present with immunodeficiency and/or immune dysregulation, have revealed the importance of balanced STAT3 signaling in lymphocyte differentiation and function, and immune homeostasis. Here, we report a novel missense variant of unknown significance in the DNA binding domain of STAT3 in a patient who experienced hypogammaglobulinemia, lymphadenopathy, hepatosplenomegaly, immune thrombocytopenia, eczema and enteropathy over a 35-year period.

Real-world trends and future projections of the prevalence of cirrhosis and hepatic encephalopathy among commercially and Medicare-insured adults in the United States.

Objectives: Describing cirrhosis and hepatic encephalopathy (HE) burden over time can inform clinical management and resource allocation. Using health care claims data, this observational study examined recent trends in the prevalence of cirrhosis and HE and associated health care resource utilization among commercially and Medicare-insured adults in the United States (US).

Methods: Data from the MarketScan Commercial Claims and Encounters Database and 100% Medicare Research Identifiable Files were analyzed (2007-2020).

Heterozygous UBR5 variants result in a neurodevelopmental syndrome with developmental delay, autism, and intellectual disability.

E3 ubiquitin ligases have been linked to developmental diseases including autism, Angelman syndrome (UBE3A), and Johanson-Blizzard syndrome (JBS) (UBR1). Here, we report variants in the E3 ligase UBR5 in 29 individuals presenting with a neurodevelopmental syndrome that includes developmental delay, autism, intellectual disability, epilepsy, movement disorders, and/or genital anomalies. Their phenotype is distinct from JBS due to the absence of exocrine pancreatic insufficiency and the presence of autism, epilepsy, and, in some probands, a movement disorder.

Ethics and clinical research: How can the Ethics Committees (CPPs) and Committees for Research Ethics (CER) evolve?

In line with the spirit of the Giens workshops, this article reports on the recommended evolution of the Ethics Committees (CPPs) and the Committees for Research Ethics (CER) in France. These committees play a crucial role in the ethical evaluation of clinical research projects, a process that has become more complex, particularly in view of recent legislative, regulatory and methodological developments. This reflection highlights the current challenges faced by the CPPs, including the increasing workload, the complexity of the issues to be addressed and the need for better use of their resources.

Histidine limitation alters plant development and influences the TOR network.

Plant growth depends on growth regulators, nutrient availability, and amino acids levels, all of which influence cell wall formation and cell expansion. Cell wall integrity and structures are surveyed and modified by a complex array of cell wall integrity sensors, including LRR-extensins (LRXs) that bind RALF (rapid alkalinization factor) peptides with high affinity and help to compact cell walls. Expressing the Arabidopsis root-hair specific LRX1 without the extensin domain, which anchors the protein to the cell wall, has a negative effect on root hair development.

Using Near-Infrared Irradiation for Heating Mechanochemical Reactions in Organic-Dye-Doped Epoxy Milling Jars.

Albeit mechanochemistry is a novel promising technology that gives access to reactivity under solvent-free conditions, heating such reactions is sometimes compulsory to obtain satisfactory results in terms of conversion, selectivity and/or yield. In this work, we developed a novel approach using a dye that absorbs NIR photons and release the energy as heat. Hence, de novo milling jars in epoxy resin doped with the dye were thus produced to obtain reactors that would produce heat upon irradiation at 850 nm.

Real-World Evaluation of Treatment Patterns and Clinical Outcomes among Patients With Chronic Myeloid Leukemia in Chronic Phase Treated With Asciminib in Clinical Practice in the United States: Real-world asciminib treatment outcomes in CML-CP.

Background: Tyrosine kinase inhibitors (TKIs) are the mainstay treatment for chronic myeloid leukemia in chronic phase (CML-CP). Asciminib, an ABL/BCR::ABL1 inhibitor which binds to the myristoyl pocket, was recently approved in the US for patients with CML-CP previously treated with ≥2 TKIs or with the T315I mutation. This study described treatment patterns and real-world clinical outcomes among patients with CML-CP treated with asciminib in US clinical practice.

A Novel Case of IFNAR1 Deficiency Identified a Common Canonical Splice Site Variant in DOCK8 in Western Polynesia: The Importance of Validating Variants of Unknown Significance in Under-Represented Ancestries.

Advanced genomic technologies such as whole exome or whole genome sequencing have improved diagnoses and disease outcomes for individuals with genetic diseases. Yet, variants of unknown significance (VUS) require rigorous validation to establish disease causality or modification, or to exclude them from further analysis. Here, we describe a young individual of Polynesian ancestry who in the first 13 mo of life presented with SARS-CoV-2 pneumonia, severe enterovirus meningitis and adenovirus gastroenteritis, and severe adverse reaction to MMR vaccination.

γ-tubulin complex controls the nucleation of tubulin-based structures in Apicomplexa.

Apicomplexan parasites rely on tubulin structures throughout their cell and life cycles, particularly in the polymerization of spindle microtubules to separate the replicated nucleus into daughter cells. Additionally, tubulin structures, including conoid and subpellicular microtubules, provide the necessary rigidity and structure for dissemination and host cell invasion. However, it is unclear whether these tubulin structures are nucleated via a highly conserved γ-tubulin complex or through a specific process unique to apicomplexans.

Healthcare resource utilization and costs associated with psychiatric comorbidities in pediatric patients with attention-deficit/hyperactivity disorder: a claims-based case-cohort study.

Background: Attention-deficit/hyperactivity disorder (ADHD) has been shown to pose considerable clinical and economic burden; however, research quantifying the excess burden attributable to common psychiatric comorbidities of ADHD among pediatric patients is scarce. This study assessed the impact of anxiety and depression on healthcare resource utilization (HRU) and healthcare costs in pediatric patients with ADHD in the United States.

Methods: Patients with ADHD aged 6-17 years were identified in the IQVIA PharMetrics Plus database (10/01/2015-09/30/2021).

Sex differences in treatment of familial hypercholesterolaemia: a meta-analysis.

Background And Aims: Familial hypercholesterolaemia (FH) is a highly prevalent monogenic disorder characterized by elevated LDL cholesterol (LDL-C) levels and premature atherosclerotic cardiovascular disease. Sex disparities in diagnosis, lipid-lowering therapy, and achieved lipid levels have emerged worldwide, resulting in barriers to care in FH. A systematic review was performed to investigate sex-related disparities in treatment, response, and lipid target achievement in FH (PROSPERO, CRD42022353297).

The economic impact of suboptimal treatment and treatment switch among patients with Crohn's disease treated with a first-line biologic - A US retrospective claims database study.

Aims: Suboptimal treatment indicators, including treatment switch, are common among patients with Crohn's disease (CD), but little is known about their associated healthcare resource utilization (HRU) and costs. This study assessed the impact of suboptimal treatment indicators on HRU and costs among adults with CD newly treated with a first-line biologic.

Methods: Adult patients with CD were identified in the IBM MarketScan Commercial Subset (10/01/2015-03/31/2020).

Clinical and economic burden of medicare beneficiaries with multiple myeloma and renal impairment: An observational study.

Evidence on real-world clinical and economic outcomes in patients with multiple myeloma (MM) and renal impairment (RI) is limited in the United States. This retrospective study aimed to generate an updated comprehensive assessment of the clinical and economic outcomes of MM patients with RI using the Medicare research identifiable files data with Part D linkage, which might assist in assessing the total clinical and socioeconomic burden of these high-risk and challenging-to-treat patients. Treatment patterns and clinical and economic outcomes in first line (1L) to fourth line (4L) therapy were described in Medicare beneficiaries (2012 to 2018) for MM patients with RI (RI MM cohort).

Patient preferences for treatment attributes in moderate-to-severe atopic dermatitis: a discrete choice experiment.

Evidence on treatment preferences of patients with moderate-to-severe atopic dermatitis (AD) in the United States (US) is limited and an assessment of treatment preferences in this group is warranted. An online discrete choice experiment survey was conducted (June 2023) among US adults with self-reported moderate-to-severe AD or experience with systemic therapy who had inadequate response to topical treatments. Preference weights estimated from conditional logistic regression models were used to calculate willingness to trade off and attributes' relative importance (RI).

FLT3L governs the development of partially overlapping hematopoietic lineages in humans and mice.

FMS-related tyrosine kinase 3 ligand (FLT3L), encoded by FLT3LG, is a hematopoietic factor essential for the development of natural killer (NK) cells, B cells, and dendritic cells (DCs) in mice. We describe three humans homozygous for a loss-of-function FLT3LG variant with a history of various recurrent infections, including severe cutaneous warts. The patients' bone marrow (BM) was hypoplastic, with low levels of hematopoietic progenitors, particularly myeloid and B cell precursors.
