Purpose: Burnout is prevalent in radiation oncology (RO), and an increased focus on promoting physician wellness and formalizing wellness-directed efforts has transpired in recent years. We aimed to characterize current wellness leadership positions and efforts within academic RO departments.

Methods And Materials: Academic RO department chairs were contacted to inquire whether they had a departmental wellness leader with a request for leader contact information, if applicable.

Dispersion-based cognitive intra-individual variability in former American football players: Association with traumatic encephalopathy syndrome, repetitive head impacts, and biomarkers.

Exposure to repetitive head impacts (RHI), such as those experienced in American football, is linked to cognitive dysfunction later in life. Traumatic encephalopathy syndrome (TES) is a proposed clinical syndrome thought to be linked to neuropath-ology of chronic traumatic encephalopathy (CTE), a condition associated with RHI from football. Cognitive intra-individual variability (d-CIIV) measures test-score dispersion, indicating cognitive dysfunction.

Acceptability and Feasibility of Self-Collected Dried Blood Spot Specimens for Viral Load Monitoring among Rural Older People Living with HIV.

Self-collected dried blood spot (DBS) samples may be useful in monitoring viral load (VL) in research studies or clinically given that they eliminate the need for participants to travel to study sites or laboratories. Despite this, little information exists about monitoring VL using DBS self-collected at home, and no information exists on DBS for this use among older rural people living with HIV (PLH), a population that could benefit from self-collection given difficulty accessing care. We report on the feasibility and acceptability of self-collected DBS samples, DBS VL results, concordance between self-reported and DBS VL, and factors associated with DBS detectable VL in a rural Southern U.

How likely is it that a virus or bacteria is causing a patient's symptoms? A new approach to interpret the outcome from multi-pathogen PCR.

Background: Whether a detected virus or bacteria is a pathogen that may require treatment, or is merely a commensal 'passenger', remains confusing for many infections. This confusion is likely to increase with the wider use of multi-pathogen PCR.

Objectives: To propose a new statistical procedure to analyse and present data from case-control studies clarifying the probability of causality.

ISCT MSC committee statement on the US FDA approval of allogenic bone-marrow mesenchymal stromal cells.

The December 2024 US Food and Drug Administration (FDA) approval of Mesoblast's Ryoncil (remestemcel-L-rknd)-allogeneic bone marrow mesenchymal stromal cell (MSC(M)) therapy-in pediatric acute steroid-refractory graft-versus-host-disease finally ended a long-lasting drought on approved MSC clinical products in the United States. While other jurisdictions-including Europe, Japan, India, and South Korea-have marketed autologous or allogeneic MSC products, the United States has lagged in its approval. The sponsor's significant efforts and investments, working closely with the FDA addressing concerns regarding clinical efficacy and consistent MSC potency through an iterative process that spanned several years, was rewarded with this landmark approval.

Depression symptom severity and behavioral impairment in school-going adolescents in Uganda.

Background: During adolescence, a critical developmental phase, cognitive, psychological, and social states interact with the environment to influence behaviors like decision-making and social interactions. Depressive symptoms are more prevalent in adolescents than in other age groups which may affect socio-emotional and behavioral development including academic achievement. Here, we determined the association between depression symptom severity and behavioral impairment among adolescents enrolled in secondary schools of Eastern and Central Uganda.

Liquid-based encapsulation for implantable bioelectronics across broad pH environments.

Wearable and implantable bioelectronics that can interface for extended periods with highly mobile organs and tissues across a broad pH range would be useful for various applications in basic biomedical research and clinical medicine. The encapsulation of these systems, however, presents a major challenge, as such devices require superior barrier performance against water and ion penetration in challenging pH environments while also maintaining flexibility and stretchability to match the physical properties of the surrounding tissue. Current encapsulation materials are often limited to near-neutral pH conditions, restricting their application range.

Dual targeting PPARα and NPC1L1 metabolic vulnerabilities blocks tumorigenesis.

Dysregulated lipid metabolism is linked to tumor progression. In this study, we identified Niemann-Pick C1-like 1 (NPC1L1) as a downstream effector of PKM2. In breast cancer cells, PKM2 knockout (KO) enhanced NPC1L1 expression while downregulating peroxisome proliferator-activated receptor α (PPARα) signaling pathway.

Ensuring Medical Device Safety: The Role of Standards Organizations and Regulatory Bodies.

Medical devices significantly enhance healthcare by integrating advanced technology to improve patient outcomes. Ensuring their safety and reliability requires a delicate balance between innovation and rigorous oversight, managed through the collaborative efforts of standards development organizations, standards accrediting organizations, and regulatory agencies such as the U.S.

High-Intensity Focused Ultrasound Ablation for Primary or Salvage Prostate Cancer Therapy: Initial Outcomes in the Veteran Healthcare Setting.

High-Intensity Focused Ultrasound (HIFU) provides comparable oncologic, erectile, and urinary outcomes to standard-of-care options for localized prostate cancer. This study reports the largest United States series of HIFU in veterans for both primary and salvage therapies. We retrospectively analyzed the outcomes of 43 veterans treated at the Michael E.

Enhancing Radiation Therapy Response in Prostate Cancer Through Metabolic Modulation by Mito-Lonidamine: A H and P Magnetic Resonance Spectroscopy Study.

Radiation therapy (RT) is the cornerstone treatment for prostate cancer; however, it frequently induces gastrointestinal and genitourinary toxicities that substantially diminish the patients' quality of life. While many individuals experience transient side effects, a subset endures persistent, long-term complications. A promising strategy to mitigate these toxicities involves enhancing tumor radiosensitivity, potentially allowing for lower radiation doses.

Integrative proteogenomic analysis identifies COL6A3-derived endotrophin as a mediator of the effect of obesity on coronary artery disease.

Obesity strongly increases the risk of cardiometabolic diseases, yet the underlying mediators of this relationship are not fully understood. Given that obesity strongly influences circulating protein levels, we investigated proteins mediating the effects of obesity on coronary artery disease, stroke and type 2 diabetes. By integrating two-step proteome-wide Mendelian randomization, colocalization, epigenomics and single-cell RNA sequencing, we identified five mediators and prioritized collagen type VI α3 (COL6A3).

A paper-based HPV E7 oncoprotein assay for cervical precancer detection at the point of care.

Cervical cancer, while preventable through screening and treatment of cervical precancer, remains a global challenge with a disproportionately high burden of disease in resource-limited settings, especially in low- and middle-income countries (LMICs). Lack of affordable, easy-to-use screening and diagnostic tests contributes to this disparity. Most commercially available tests are not appropriate for use in LMICs due to resource constraints.

A Call for a Neoadjuvant Kidney Cancer Consortium: Lessons Learned from Other Cancer Types.

Neoadjuvant systemic treatment strategies have improved outcomes in several solid tumour types. This success has not yet been replicated in renal cell carcinoma (RCC). A consensus and international collaboration are urgently needed for the development of adaptive perioperative immunotherapy strategies for patients with RCC at high risk of recurrence.

Characteristics of children and adolescents with multidrug-resistant and rifampicin-resistant tuberculosis and their association with treatment outcomes: a systematic review and individual participant data meta-analysis.

Background: There are few data on the treatment of children and adolescents with multidrug-resistant (MDR) or rifampicin-resistant (RR) tuberculosis, especially with more recently available drugs and regimens. We aimed to describe the clinical and treatment characteristics and their associations with treatment outcomes in this susceptible population.

Methods: We conducted a systematic review and individual participant data meta-analysis.

Radiobiologically equivalent deformable dose mapping for re-irradiation Planning: Implementation, Robustness, and dosimetric benefits.

Background: Re-irradiation in radiotherapy presents complexities that require dedicated tools to generate optimal re-treatment plans. This study presents a robust workflow that considers fractionation size, anatomical variations between treatments, and cumulative bias doses to improve the re-irradiation planning process.

Methods: The workflow was automated in MIM® Software and the Elekta© Monaco® treatment planning system.

Association between pituitary adenoma consistency, resection techniques, and patient outcomes: a single-institution experience.

Objective: The present study aimed to investigate the association between pituitary adenoma (PA) consistency and other measurable tumor characteristics, extent of resection (EOR), postoperative complications, and outcomes.

Methods: In total, 507 PA resections were intraoperatively assigned a consistency grade from 1 (cystic/hemorrhagic tumors) to 5 (calcified tumors) based on intraoperative tumor characteristics. Tumor consistency was analyzed in tertiles (grades 1 and 2, grade 3, and grades 4 and 5) to determine associations with tumor characteristics, EOR, recurrence, postoperative outcomes, and complications.

The Fit Older Adult with Acute Myeloid Leukemia: Clinical Challenges to Providing Evidence-Based Frontline Treatment.

Recent advances in acute myeloid leukemia (AML) come from studies investigating younger (age<60 years) adults or older (age≥75 years) or less fit adults. Uncertainty exists for the management of otherwise healthy adults with AML in their 60s and 70s, which also represents a significant proportion of AML cases. We discuss current considerations in older, fit adults with AML including determination of fitness, what factors beyond fitness should be assessed, and finally what challenges and innovations lie ahead to improve outcomes for these patients.

Polygenic risk discriminates Lewy body dementia from Alzheimer's disease.

Introduction: Lewy body dementia (LBD) shares genetic risk factors with Alzheimer's disease (AD), including apolipoprotein E (APOE), but is distinguishable at the genome-wide level. Polygenic risk scores (PRS) may therefore improve diagnostic classification.

Methods: We assessed diagnostic classification using AD-PRS excluding APOE (AD-PRS ), APOE risk score (APOE-RS), and plasma phosphorylated tau 181 (p-tau181), in 83 participants with LBD, 27 with positron emission tomography amyloid beta (Aβ)positive mild cognitive impairment or AD (MCI+/AD), and 57 controls.

Di-Genic Inheritance in Genodermatoses: Insights from Two Consanguineous Cases in a Reference Lebanese Center within the Middle East and North Africa (MENA) Region.

Introduction: Genodermatoses refer to a group of heterogenous rare genetic diseases with cutaneous expression. Several genodermatoses present with multisystem involvement that can range from mild to life-threatening conditions leading to increased morbidity and mortality.

Objective: Given the paucity in the literature in the field of genodermatoses, especially in the Middle East and North Africa (MENA) region, and building upon the first established genodermatoses database based in Lebanon, this study aimed to decipher the genetic basis of two different types of skin-inherited diseases (androgenic alopecia and vitiligo).
