The guided fire from within: intratumoral administration of mRNA-based vaccines to mobilize memory immunity and direct immune responses against pathogen to target solid tumors.

We investigated a novel cancer immunotherapy strategy that effectively suppresses tumor growth in multiple solid tumor models and significantly extends the lifespan of tumor-bearing mice by introducing pathogen antigens into tumors via mRNA-lipid nanoparticles. The pre-existing immunity against the pathogen antigen can significantly enhance the efficacy of this approach. In mice previously immunized with BNT162b2, an mRNA-based COVID-19 vaccine encoding the spike protein of the SARS-CoV-2 virus, intratumoral injections of the same vaccine efficiently tagged the tumor cells with mRNA-expressed spike protein.

Understanding water reaction pathways to control the hydrolytic reactivity of a Zn metal-organic framework.

Metal-organic frameworks (MOFs) are a class of porous materials that are of topical interest for their utility in water-related applications. Nevertheless, molecular-level insight into water-MOF interactions and MOF hydrolytic reactivity remains understudied. Herein, we report two hydrolytic pathways leading to either structural stability or framework decomposition of a MOF (ZnMOF-1).

The association between baseline viral load and long-term risk in patients with COVID-19 in Hong Kong: a territory-wide study.

COVID-19 can increase the long-term risk of multiorgan dysfunction.

We aimed to investigate the post-discharge rates of hospitalization and association with baseline viral load in all patients with COVID-19 in Hong Kong.

Transforming the Medical School Admissions Process: Prioritizing Team-Based Skills and Patient-Centered Values.

This article examines the need for reform in medical school admissions to better align with the collaborative and patient-centered nature of contemporary healthcare. Traditional admissions processes prioritize academic excellence, often neglecting essential interpersonal and team-based skills. We advocate for several strategies to address this gap.

Beauty growth-mindset promotes prosocial and altruistic behavior.

The effects of beauty on judgment and behavior are well-established and somewhat "unidirectional" (i.e., it seems that only beautiful people reap social benefits).

Revitalizing Musculoskeletal Healthcare: A Strategic Approach to Value-Based Care.

Background: Value-based care (VBC) emphasizes patient outcomes over service volume, representing a significant shift in health care delivery. Musculoskeletal (MSK) health care, with over $300 billion in annual expenditures, has lagged behind other specialties in adopting VBC. Key barriers include misaligned incentives and fragmented care delivery.

Basics of Orthopaedic Commercial and Government Bundling.

Background: The health care system is transitioning from fee-for-service models to value-based care frameworks, with bundled payments emerging as a promising approach to improve cost efficiency and patient outcomes. Bundled payments consolidate costs for multiple services into a single payment for specific treatments or conditions. This study reviews the development and implementation of bundling models in orthopaedics, comparing government and commercial approaches and discussing their benefits and challenges.

Practical Implications of Value-Based Care in the Setting of Ambulatory Surgery Centers.

Background: Ambulatory surgery centers (ASCs) are increasingly replacing traditional hospital settings for orthopaedic procedures, driven by advancements in surgical techniques, anesthesia, and enhanced recovery protocols. These innovations enable complex procedures to be performed safely in outpatient settings. ASCs align with value-based care (VBC) principles by offering cost-effective, high-quality, and patient-centered care.

Hyperglycemia-triggered lipid peroxidation destabilizes STAT4 and impairs anti-viral Th1 responses in type 2 diabetes.

Patients with type 2 diabetes (T2D) are more susceptible to severe respiratory viral infections, but the underlying mechanisms remain elusive. Here, we show that patients with T2D and coronavirus disease 2019 (COVID-19) infections, and influenza-infected T2D mice, exhibit defective T helper 1 (Th1) responses, which are an essential component of anti-viral immunity. This defect stems from intrinsic metabolic perturbations in CD4 T cells driven by hyperglycemia.

Temperature-induced mobility in octacalcium phosphate impacts crystal symmetry: water dynamics studied by NMR crystallography.

Octacalcium phosphate (OCP, Ca(PO)(HPO)·5HO) is a notable calcium phosphate due to its biocompatibility, making it a widely studied material for bone substitution. It is known to be a precursor of bone mineral, but its role in biomineralisation remains unclear. While the structure of OCP has been the subject of thorough investigations (including using Rietveld refinements of X-ray diffraction data, and NMR crystallography studies), important questions regarding the symmetry and H-bonding network in the material remain.
