Tips for Harnessing the Educational Potential of Tumor Boards for Medical Students.

This paper explores the underutilized educational potential of tumor boards as a platform for medical student education. Acknowledging the complexity and multidisciplinary nature of tumor boards, we propose 12 strategic interventions aimed at integrating undergraduate medical students into these meetings to enhance their learning experience. These strategies emphasize active student engagement, critical analysis, patient interaction, reflective practice, and the integration of digital learning tools, with a focus on fostering an in-depth understanding of team-based, patient-focused oncology care.

- a large-scale dataset of 3D medical shapes for computer vision.

Objectives: The shape is commonly used to describe the objects. State-of-the-art algorithms in medical imaging are predominantly diverging from computer vision, where voxel grids, meshes, point clouds, and implicit surface models are used. This is seen from the growing popularity of ShapeNet (51,300 models) and Princeton ModelNet (127,915 models).

Long-term quality of life in patients with bladder cancer following radical cystectomy.

Objectives: To investigate changes in quality of life (QoL) up to 8 years after radical cystectomy (RC) and compare QoL after RC with a gender- and age-matched Dutch normative population. Furthermore, we aimed to identify patient characteristics associated with QoL and QoL trajectories after RC.

Patients And Methods: Patients with bladder cancer were invited to complete QoL questionnaires at 3-month intervals in the first year and yearly thereafter.

Integrating planetary health education into tertiary curricula: a practical toolbox for implementation.

Objective: To present a series of case studies from our respective countries and disciplines on approaches to implementing the Planetary Health Education Framework in university health professional education programs, and to propose a curriculum implementation and evaluation toolbox for educators to facilitate the adoption of similar initiatives in their programs. We emphasize the importance of applying an Indigenous lens to curriculum needs assessment, development, implementation, and evaluation.

Methods: Case studies from Australia and United States were collated using a six-stage design-based educational research framework (Focus, Formulation, Contextualization, Definition, Implementation, Evaluation) for teaching planetary health and methods of curriculum evaluation.

Influence of Wobbling Tryptophan and Mutations on PET Degradation Explored by QM/MM Free Energy Calculations.

Plastic-degrading enzymes, particularly poly(ethylene terephthalate) (PET) hydrolases, have garnered significant attention in recent years as potential eco-friendly solutions for recycling plastic waste. However, understanding of their PET-degrading activity and influencing factors remains incomplete, impeding the development of uniform approaches for enhancing PET hydrolases for industrial applications. A key aspect of PET hydrolase engineering is optimizing the PET-hydrolysis reaction by lowering the associated free energy barrier.

Purpose: Patient-reported outcome measures (PROMs) are questionnaires completed by patients to gain insight in their health-related quality of life. However, patients often find the interpretation of PROMS challenging. A personalized narrative, i.

Moving beyond barriers: a mixed-method study to develop evidence-based strategies to improve implementation of PROMs in clinical oncology care.

Purpose: This study aimed to identify feasible, evidence-based strategies to improve the use of Patient-reported outcome measures (PROMs) implemented in clinical oncology practice.

Methods: A mixed-method study involving observations of consultations and semi-structured interviews with patients and healthcare professionals (HCPs) was conducted to identify facilitators and barriers for using PROMs; barriers and facilitators were structured following the Theoretical Domains Framework. For each barrier, evidence-based improvement strategies were selected using the Behaviour Change Techniques Taxonomy v1.

Molecular basis of hyper-thermostability in the thermophilic archaeal aldolase MfnB.

Methanogenic archaea are chemolithotrophic prokaryotes that can reduce carbon dioxide with hydrogen gas to form methane. These microorganisms make a significant contribution to the global carbon cycle, with methanogenic archaea from anoxic environments estimated to contribute > 500 million tons of global methane annually. Archaeal methanogenesis is dependent on the methanofurans; aminomethylfuran containing coenzymes that act as the primary C acceptor molecule during carbon dioxide fixation.

Ancestry-aligned polygenic scores combined with conventional risk factors improve prediction of cardiometabolic outcomes in African populations.

Background: Cardiovascular diseases (CVD) are a major health concern in Africa. Improved identification and treatment of high-risk individuals can reduce adverse health outcomes. Current CVD risk calculators are largely unvalidated in African populations and overlook genetic factors.

Antibiotic origami: selective formation of spirotetronates in abyssomicin biosynthesis.

The abyssomicins are a structurally intriguing family of bioactive natural products that include compounds with potent antibacterial, antitumour and antiviral activities. The biosynthesis of the characteristic abyssomicin spirotetronate core occurs an enzyme-catalysed intramolecular Diels-Alder reaction, which proceeds one of two distinct stereochemical pathways to generate products differing in configuration at the C15 spirocentre. Using the purified spirotetronate cyclases AbyU (from abyssomicin C/atrop-abyssomicin C biosynthesis) and AbmU (from abyssomicin 2/neoabyssomicin biosynthesis), in combination with synthetic substrate analogues, here we show that stereoselectivity in the spirotetronate-forming [4 + 2]-cycloaddition is controlled by a combination of factors attributable to both the enzyme and substrate.

Delineation of the complete reaction cycle of a natural Diels-Alderase.

The Diels-Alder reaction is one of the most effective methods for the synthesis of substituted cyclohexenes. The development of protein catalysts for this reaction remains a major priority, affording new sustainable routes to high value target molecules. Whilst a small number of natural enzymes have been shown capable of catalysing [4 + 2] cycloadditions, there is a need for significant mechanistic understanding of how these prospective Diels-Alderases promote catalysis to underpin their development as biocatalysts for use in synthesis.

Simulation-Guided Engineering Enables a Functional Switch in Selinadiene Synthase toward Hydroxylation.

Engineering sesquiterpene synthases to form predefined alternative products is a major challenge due to their diversity in cyclization mechanisms and our limited understanding of how amino acid changes affect the steering of these mechanisms. Here, we use a combination of atomistic simulation and site-directed mutagenesis to engineer a selina-4(15),7(11)-diene synthase (SdS) such that its final reactive carbocation is quenched by trapped active site water, resulting in the formation of a complex hydroxylated sesquiterpene (selin-7(11)-en-4-ol). Initially, the SdS G305E variant produced 20% selin-7(11)-en-4-ol.

Raman micro-spectroscopy reveals the spatial distribution of fumarate in cells and tissues.

Aberrantly accumulated metabolites elicit intra- and inter-cellular pro-oncogenic cascades, yet current measurement methods require sample perturbation/disruption and lack spatio-temporal resolution, limiting our ability to fully characterize their function and distribution. Here, we show that Raman spectroscopy (RS) can directly detect fumarate in living cells in vivo and animal tissues ex vivo, and that RS can distinguish between Fumarate hydratase (Fh1)-deficient and Fh1-proficient cells based on fumarate concentration. Moreover, RS reveals the spatial compartmentalization of fumarate within cellular organelles in Fh1-deficient cells: consistent with disruptive methods, we observe the highest fumarate concentration (37 ± 19 mM) in mitochondria, where the TCA cycle operates, followed by the cytoplasm (24 ± 13 mM) and then the nucleus (9 ± 6 mM).

"Let's put it this way: you can't really live without it" - digital technologies in routine palliative care delivery: an explorative qualitative study with patients and their family caregivers in Germany.

Background: Despite ongoing efforts to integrate palliative care into the German healthcare system, challenges persist, particularly in areas where infrastructure does not fully support digital technologies (DT). The increasing importance of digital technology (DT) in palliative care delivery presents both opportunities and challenges.

Objective: This study aimed to explore the perspectives and preferences of palliative care patients and their family caregivers regarding the use of DT in care delivery.

Epistasis arises from shifting the rate-limiting step during enzyme evolution of a β-lactamase.

Epistasis, the non-additive effect of mutations, can provide combinatorial improvements to enzyme activity that substantially exceed the gains from individual mutations. Yet the molecular mechanisms of epistasis remain elusive, undermining our ability to predict pathogen evolution and engineer biocatalysts. Here we reveal how directed evolution of a β-lactamase yielded highly epistatic activity enhancements.

: A Flexible Electrostatic Machine Learning Embedding Package for Multiscale Molecular Dynamics Simulations.

We present in this work the package (https://github.com/chemle/emle-engine)─the implementation of a new machine learning embedding scheme for hybrid machine learning potential/molecular-mechanics (ML/MM) dynamics simulations. The package is based on an embedding scheme that uses a physics-based model of the electronic density and induction with a handful of tunable parameters derived from properties of the subsystem to be embedded.

Spearheading a new era in complex colloid synthesis with TPM and other silanes.

Colloid science has recently grown substantially owing to the innovative use of silane coupling agents (SCAs), especially 3-trimethoxysilylpropyl methacrylate (TPM). SCAs were previously used mainly as modifying agents, but their ability to form droplets and condense onto pre-existing structures has enabled their use as a versatile and powerful tool to create novel anisotropic colloids with increasing complexity. In this Review, we highlight the advances in complex colloid synthesis facilitated by the use of TPM and show how this has driven remarkable new applications.

Electric Fields Are a Key Determinant of Carbapenemase Activity in Class A β-Lactamases.

Resistance to antibiotics is a public health crisis. Although carbapenems are less susceptible to resistance than other β-lactam antibiotics, β-lactamases mediating resistance against these drugs are spreading. Here, we dissect the contributions of electric fields to carbapenemase activity in class A β-lactamases.

Addition of tumor microenvironment immune cell composition to improve the performance of a predictive model for oral squamous cell carcinoma.
