Using patient preference information (PPI) to incorporate patient voices into the drug development lifecycle can help align therapies with the needs and values of patients. However, several barriers have limited the use of PPI, including a lack of clarity on its use by decision-makers, a need for greater decision-maker trust in PPI, and a lack of time, budgets, and access to specialist expertise. The value proposition for PPI could be enhanced by making it FAIR: Findable, Accessible, Interoperable, and Reusable.

Background: In the context of injectable biologic products approved or in development for chronic spontaneous urticaria (CSU), it is important to capture which treatment attributes matter most to patient and what trade-offs patients are willing to make.

Objectives: The CHOICE-CSU study aimed to quantify patient preferences toward injectable treatment attributes among patients with CSU, inadequately controlled by H1-antihistamines.

Methods: This was a two-phase cross-sectional patient preference study in adult patients with a diagnosis of CSU, inadequately controlled by H1-antihistamines.

Background: Previous studies have shown that in-beam magnetic resonance imaging (MRI) can be used to visualize a proton beam during the irradiation of liquid-filled phantoms. The beam energy- and current-dependent local image contrast observed in water was identified to be predominantly caused by beam-induced buoyant convection and associated flow effects. Besides this flow dependency, the MR signal change was found to be characterized by a change in the relaxation time of water, hinting at a radiochemical contribution, which was hypothesized to lie in oxygen depletion-evoked relaxation time lengthening.

Nanobodies or variable antigen-binding domains (VH) derived from heavy chain-only antibodies (HcAb) occurring in the Camelidae family offer certain superior physicochemical characteristics like enhanced stability, solubility, and low immunogenicity compared to conventional antibodies. Their efficient antigen-binding capabilities make them a preferred choice for next-generation small biologics. In the present work, we design an anti-SARS-CoV-2 bi-paratopic nanobody drug conjugate by screening a nanobody database.

Purpose: This brief report aims to summarize and discuss the methodologies of eXplainable Artificial Intelligence (XAI) and their potential applications in surgery.

Methods: We briefly introduce explainability methods, including global and individual explanatory features, methods for imaging data and time series, as well as similarity classification, and unraveled rules and laws.

Results: Given the increasing interest in artificial intelligence within the surgical field, we emphasize the critical importance of transparency and interpretability in the outputs of applied models.

Background: Primary percutaneous coronary intervention (PPCI) and fibrinolytic or thrombolytic therapy are common treatments for ST-elevation myocardial infarction (STEMI). Primary percutaneous coronary intervention is more effective than thrombolytic therapy, but fibrinolytic therapy is still a preferable option for patients with limited access to healthcare. Alteplase is a tissue plasminogen activator (tPA) used to treat acute myocardial infarction, acute ischemic stroke, and pulmonary embolism.

Background: Robotic hepatectomy has been increasingly adopted for the treatment of hepatocellular carcinoma (HCC). However, the ideal technique of parenchymal transection in robotic hepatectomy has been a matter of ongoing debate in literature.

Patients And Methods: In this video, we demonstrate the technique of robotic anatomical segment VIII resection using the scissor hepatectomy technique for parenchymal transection on a 75-year-old male patient with a solitary HCC lesion.

The digitalization of society increasingly blurs boundaries between analog and digital worlds, offering opportunities such as telemedicine and global connectivity through digital platforms. However, it also presents risks, including cyberbullying, addiction potential, harmful content, misinformation, and privacy concerns from data breaches and surveillance technologies. Social media, with its global reach, amplifies both opportunities for positive engagement and the responsibility to navigate largely unregulated content.

Background: The persistently low number of postmortem organ donations in Germany has repeatedly led to political discussions and most recently to the amendment of the Transplantation Act with the strengthening of the role of the transplantation officer and the introduction of a register to document the will to donate. The background to these decisions was the assumption that a relevant proportion of potential organ donors in hospitals were being overlooked and not reported. However, due to the lack of guidelines as to when a potential organ donor must be reported to the DSO ("Deutsche Stiftung Organspende"), the existing data is only of limited validity.

Li-Fraumeni syndrome is a cancer predisposition syndrome caused by pathogenic TP53 germline variants and associated with a high lifelong cancer risk. We analysed the German LFS registry that contains data on 304 individuals. Cancer phenotypes were correlated with variants grouped according to their ability to transactivate target genes in a yeast assay using a traditional (non-functional, partially-functional) and a novel (clusters A, B, C) classification of variants into different groups.

Aminopolyphosphonates (APPs) are widely used as chelating agents, and their increasing release into the environment has raised concerns due to their transformation into aminomethylphosphonic acid (AMPA) and glyphosate, compounds of controversial environmental impact. This transformation highlights the urgent need for detailed studies under controlled conditions. Despite the availability of various methods for quantifying individual aminopolyphosphonates and aminomonophosphonates, a green, low-cost approach for the simultaneous quantification of APPs and their transformation products in laboratory experiments has been lacking.

Terminal metal-phosphorus (M-P) complexes are of significant contemporary interest as potential platforms for P-atom transfer (PAT) chemistry. Decarbonylation of metal-phosphaethynolate (M-PCO) complexes has emerged as a general synthetic approach to terminal M-P complexes. M-P complexes that are stabilized by strong M-P multiple bonds are kinetically persistent and isolable.

Previous research has shown that, when multiple similar items are maintained in working memory, recall precision declines. Less is known about how heterogeneous sets of items across different features within and between modalities impact recall precision. In two experiments, we investigated modality (Experiment 1, n = 79) and feature-specific (Experiment 2, n = 154) load effects on working memory performance.

Glycolipids are known to stabilize biomembrane multilayers through preferential sugar-sugar interactions that act as weak transient membrane cross-links. Here, we use small-angle and quasi-elastic neutron scattering on oligolamellar phospholipid vesicles containing defined glycolipid fractions in order to elucidate the influence of glycolipids on membrane mechanics and dynamics. Small-angle neutron scattering (SANS) reveals that the oligolamellar vesicles (OLVs) obtained by extrusion are polydisperse with regard to the number of lamellae, , which renders the interpretation of the quasi-elastic neutron spin echo (NSE) data nontrivial.
