Dyad leadership blueprint: nine strategies for effective collaboration.

Background/aim: The physician-administrator dyads are a strategic method of collaboration in healthcare organisations. Dyad leaders are part of a multidisciplinary team that integrates their expertise to generate better patient, physician, and organisational outcomes. An assumption of team science is that diverse experts, while knowledgeable, struggle to work together to resolve problems because of their vastly different decision-making and implementation strategies.

Parenting Stress in Tuberous Sclerosis Complex.

Background: Tuberous sclerosis complex (TSC) is a multisystemic genetic disorder with clinical variability. As the needs of children with TSC may differ, parenting demands may similarly differ. Characterizing parenting stress, or emotional maladaptation from parenting duties, can enable health care providers to assist parents of children with TSC.

Letetresgene Autoleucel in Advanced/Metastatic Myxoid/Round Cell Liposarcoma.

Purpose: The cancer/testis antigen New York esophageal squamous cell carcinoma 1 (NY-ESO-1) is a promising target in myxoid/round cell liposarcoma (MRCLS).

Patients underwent a reduced-dose (cohort 1) or standard-dose (cohort 2) lymphodepletion regimen (LDR).

CA-125 as a Biomarker in Renal Medullary Carcinoma: Integrated Molecular Profiling, Functional Characterization, and Prospective Clinical Validation.

Purpose: Renal medullary carcinoma (RMC) is a highly aggressive malignancy defined by the loss of the SMARCB1 tumor suppressor. It mainly affects young individuals of African descent with sickle cell trait, and it is resistant to conventional therapies used for other renal cell carcinomas. This study aimed to identify potential biomarkers for early detection and disease monitoring of RMC.

Bone-Induced Her2 Promotes Secondary Metastasis in HR+/Her2- Breast Cancer.

Bone metastases can disseminate to secondary sites and promote breast cancer progression creating additional clinical challenges. The mechanisms contributing to secondary metastasis are barely understood. Here, we evaluate the prediction power of Her2-expressing (Her2E) circulating tumor cells (CTCs) after analyzing over 13,000 CTCs from a cohort of 137 metastatic breast cancer (MBC) patients with initial HR+/Her2- status and employ preclinical models of bone metastasis (BM) to validate the role of Her2E CTCs in multi-organ metastases.

Age-associated alterations in immune and inflammatory responses in captive olive baboons ().

Introduction: Advanced age is a primary risk factor for many chronic diseases and conditions; however, age-related immune dysregulation is not well understood. Animal models, particularly those that resemble human age-related physiological changes, are needed to better understand immunosenescence and to improve health outcomes. Here, we explore the utility of the olive baboon (Papio anubis) in studying age-related changes to the immune system and understanding mechanisms of immunosenescence.

Revisiting phosphoregulation of Cdc25C during M-phase induction.

Cdc25C undergoes a sudden and substantial gel mobility shift at M-phase onset, correlating with abrupt activation of both Cdc25C and Cdk1 activities. A positive feedback loop between Cdk1 and Cdc25C has been used to explain this hallmark phenomenon. Here, we demonstrate that the M-phase supershift and robust activation of Cdc25C are due to the site-comprehensive phosphorylation of its long intrinsically disordered regulatory domain without requiring Cdk1 or other major mitotic kinase activities.

A novel case of glial transdifferentiation in renal medullary carcinoma brain metastasis.

Renal medullary carcinoma is a rare undifferentiated tumor of the kidney associated with sickle cell trait and characterized by INI1 (SMARCB1) loss. Although metastasis to lungs, lymph nodes, and bone is commonly reported, distant spread to the central nervous system almost never occurs. Here we present an unusual case of a patient with renal medullary carcinoma with metastasis to the brain following treatment which included tazemetostat, an EZH2 inhibitor.

Exploring the Different Impacts of Ketamine on Neurotrophic Factors and Inflammatory Parameters in a Cecal Ligation and Puncture-Induced Sepsis Model.

Given ketamine's conflicting impacts on the central nervous system, investigating its effects within an inflammatory context becomes crucial. This study aimed to assess the impact of varying ketamine doses on neurotrophin and inflammatory cytokine levels within the brains of rats submitted to the sepsis model. Wistar rats were submitted to the cecal ligation and puncture (CLP) model of sepsis.

A dual role of Cohesin in DNA DSB repair.

Cells undergo tens of thousands of DNA-damaging events each day. Defects in repairing double-stranded breaks (DSBs) can lead to genomic instability, contributing to cancer, genetic disorders, immunological diseases, and developmental defects. Cohesin, a multi-subunit protein complex, plays a crucial role in both chromosome organization and DNA repair by creating architectural loops through chromatin extrusion.

CPT® Codes for MRI Safety - A User's Guide.

The magnetic fields of the MR environment present unique safety challenges. Medical implants and retained foreign bodies can prevent patients from undergoing MR imaging due to interactions between the magnetic fields of the MR environment and the implant or foreign body. These hazards can be addressed through careful MR safety screening and MR examination customization, often allowing these patients with implants to undergo management-altering MR imaging.

SCARB1 links cholesterol metabolism-mediated ferroptosis inhibition to radioresistance in tumor cells.

Introduction: Ferroptosis is an iron-dependent form of cell death triggered by the excessive accumulation of lipid peroxides. Understanding the regulatory mechanisms of ferroptosis and developing strategies to target this process hold significant clinical applications in tumor therapy.

Objective: Our study aims to search for novel candidate genes involved in the regulation of ferroptosis and to investigate their mechanism of action in ferroptosis and tumor therapy.

Transition to Survivorship Care for Adolescents and Young Adults (AYAs) with Acute Leukemia: Provider Perspectives.

Adolescent and young adult (AYA) survivors of acute lymphoblastic or myeloid leukemia diagnosed between the ages of 15 and 39 years are at risk for adverse late health effects following cancer treatment and require ongoing survivorship care. This study aims to understand the landscape of transitioning AYAs with leukemia from active treatment to survivorship care. A cross-sectional, anonymous online survey was sent out via listserv/email.

Extracellular vesicle-mediated VEGF-A mRNA delivery rescues ischaemic injury with low immunogenicity.

Background And Aims: Lackluster results from recently completed gene therapy clinical trials of VEGF-A delivered by viral vectors have heightened the need to develop alternative delivery strategies. This study aims to demonstrate the pre-clinical efficacy and safety of extracellular vesicles (EVs) loaded with VEGF-A mRNA for the treatment of ischaemic vascular disease.

Methods: After encapsulation of full-length VEGF-A mRNA into fibroblast-derived EVs via cellular nanoporation (CNP), collected VEGF-A EVs were delivered into mouse models of ischaemic injury.
