Tucatinib and trastuzumab in HER2-mutated metastatic breast cancer: a phase 2 basket trial.

Human epidermal growth factor receptor 2 (HER2, also known as ERBB2) signaling promotes cell growth and differentiation, and is overexpressed in several tumor types, including breast, gastric and colorectal cancer. HER2-targeted therapies have shown clinical activity against these tumor types, resulting in regulatory approvals. However, the efficacy of HER2 therapies in tumors with HER2 mutations has not been widely investigated.

Unlocking the potential of azide-phosphine Staudinger reaction for the synthesis of poly(arylene iminophosphorane)s and materials therefrom.

Iminophosphoranes with the general formula (RP═NR') have great potential in synthetic chemistry as valuable precursors/intermediates in organic synthesis or as building blocks for various organic compounds. However, the synthetic approaches and conditions to prepare iminophosphoranes are still poorly understood, limiting the utility of this chemistry for organic materials. In this article, a simple and efficient synthesis of previously unattainable poly(arylene iminophosphoranes) is reported.

Bivalves as a Mercury Bioindicator: A National Isotopic Survey along the Coast of South Korea.

Mercury (Hg) is a contaminant that poses health risks for human populations relying on seafood consumption. To mitigate its impact, identifying and monitoring Hg sources have become priorities, notably under the Minamata Convention. Bivalves are commonly used as sentinels in contaminant biomonitoring but can accumulate Hg from diverse environmental media.

Mepolizumab real-world effectiveness in severe asthma with an eosinophilic phenotype and overlapping severe allergic asthma.

Background: Some patients with severe asthma have overlapping allergic and eosinophilic phenotypes and may be eligible for anti-eosinophilic or anti-IgE biologics.

Objective: This post hoc sub-analysis assessed real-world mepolizumab effectiveness in patients with overlapping allergic and eosinophilic phenotypes, using 1-year data from the international, prospective REALITI-A study.

Methods: The clinically significant asthma exacerbation (CSE) rate was assessed 1 year prior to (pre-treatment) and following (follow-up) mepolizumab treatment, stratified by baseline total IgE levels (tIgE; <60, 60-<190, 190-<550, and ≥550 kU/L), atopic status (yes/no/unknown), prior omalizumab use (yes/no), geographic baseline omalizumab eligibility (eligible/non-eligible), and baseline tIgE level and blood eosinophil count (BEC) threshold combinations (<81 or ≥81 kU/L and <300 or ≥300 cells/µL).

Breakthrough Psoriasis in Patients Receiving Biologicals.

Background: Biological therapies, including TNF-alpha, IL12/23, IL17 and IL23 antagonists, adequately control a very high number of patients with moderate-to-severe psoriasis with an excellent long-term safety profile. However, on occasion, patients on biological therapy with stabilized disease or complete remission report episodes of sudden breakthrough psoriasis.

Aim: To study prospectively in a monocentric tertiary setting, the clinical characteristics of patients presenting a sudden breakthrough psoriasis although completely stabilized (PASI 90-100) under biological therapy.

Stacking-Engineered Ferroelectricity and Multiferroic Order in van der Waals Magnets.

Two-dimensional (2D) materials that exhibit spontaneous magnetization, polarization, or strain (referred to as ferroics) have the potential to revolutionize nanotechnology by enhancing the multifunctionality of nanoscale devices. However, multiferroic order is difficult to achieve, requiring complicated coupling between electron and spin degrees of freedom. We propose a universal method to engineer multiferroics from van der Waals magnets by taking advantage of the fact that changing the stacking between 2D layers can break inversion symmetry, resulting in ferroelectricity as well as magnetoelectric coupling.

Optical Excitation of Coherent THz Dynamics of the Rare-Earth Lattice through Resonant Pumping of f-f Electronic Transition in a Complex Perovskite DyFeO_{3}.

Resonant pumping of the electronic f-f transitions in the orbital multiplet of dysprosium ions (Dy^{3+}) in a complex perovskite DyFeO_{3} is shown to impulsively launch THz lattice dynamics corresponding to the B_{2g} phonon mode, which is dominanted by the motion of Dy^{3+} ions. The findings, supported by symmetry analysis and density-functional theory calculations, not only provide a novel route for highly selective excitation of the rare-earth crystal lattices but also establish important relationships between the symmetry of the electronic and lattice excitations in complex oxides.

E4F1 coordinates pyruvate metabolism and the activity of the elongator complex to ensure translation fidelity during brain development.

Pyruvate metabolism defects lead to severe neuropathies such as the Leigh syndrome (LS) but the molecular mechanisms underlying neuronal cell death remain poorly understood. Here, we unravel a connection between pyruvate metabolism and the regulation of the epitranscriptome that plays an essential role during brain development. Using genetically engineered mouse model and primary neuronal cells, we identify the transcription factor E4F1 as a key coordinator of AcetylCoenzyme A (AcCoA) production by the pyruvate dehydrogenase complex (PDC) and its utilization as an essential co-factor by the Elongator complex to acetylate tRNAs at the wobble position uridine 34 (U).

Evaluation of the adherence of patients with chronic inflammatory bowel diseases to a PRO telemonitoring using connected devices: a prospective monocentric study.

Background And Study Aims: Monitoring the symptoms of inflammatory bowel diseases (IBD) patients is now frequently made in the form of patient reported outcomes (PRO), rather than historical clinical activity scores. Unlike several chronic diseases, the role of telemonitoring in IBD has not yet been defined, particularly in terms of patient compliance with remote monitoring; the aim of our study was to assess patient compliance with digital monitoring of PRO as part of routine medical follow-up.

Patients And Methods: we performed a monocentric prospective study in the Gastroenterology Unit of Liège's University Hospital between May 2023 and February 2024.

A 1-month ketogenic diet in patients with migraine gives a clinical beneficial effect associated with increased latency of somatosensory thalamo-cortical activity.

Objective: Since the habituation deficit of evoked potentials could be related to abnormal thalamocortical drive, we searched for a modulatory effect of ketogenic diet (KD) on somatosensory-evoked thalamo-cortical activity. KD is effective in preventing migraine. Previous studies showed that KD normalises habituation of somatosensory and visual cortical evoked responses in parallel with a decrease in of migraine attack frequency.

Assessing Exchange-Correlation Functionals for Accurate Densities of Solids.

The success of Kohn-Sham density functional theory in predicting electronic properties from first-principles is key to its ubiquitous presence in condensed matter research. Central to this theory is the exchange-correlation functional, which can only be written in an approximate form using a handful of exact constraints. A recent criticism of these approximations is that they are designed to give an accurate description of the energy at the expense of a poor representation of the density, which is contrary to the spirit of density functional theory.

Increase in Blood Eosinophil Count Over Time and Sputum IL8 are Associated with FEV Decline in Asthma.

Background: Asthma is associated with accelerated rate of FEV decline.

Objective: To determine predictive factors associated with accelerated FEV decline in adult asthma and evaluate sputum cytokines as potential biomarkers for airflow decline.

Methods: We recruited 125 asthmatics evaluated at the asthma clinic of Liège and reevaluated them at least 5 years later.

Phenomenology of auto-induced cognitive trance using text mining: a prospective and exploratory group study.

We performed a Delphi consensus process to formulate guidelines for the use of intra-articular hyaluronic acid (IAHA) knee injection according to the patient's characteristics.

Methods: The EUROVISCO group consists of 12 members who had expertise in clinical and/or research in the field of OA and IAHA treatment.

A RESPONSE to antiIL-5 therapy in comorbid patients with chronic rhinosinusitis with nasal polyps and severe asthma: Study protocol.

Background: Chronic rhinosinusitis with nasal polyps (CRSwNP) and severe asthma (SA) are 2 frequently coexisting conditions that are, in most cases, associated with eosinophilic inflammation. The concurrence of both diseases has a negative synergistic impact on disease severity and patients' health-related quality of life. Thus, a holistic, collaborative management of these patients is a critical unmet need.
