FDG PET/CT Scan Still Can Help in Evaluation of Prostate Cancer.

Although 18F-FDG PET/CT scan is not the preferred modality to evaluate prostate cancer patients due to generally low uptake of FDG in prostate cancer cells, it can still be helpful in some selected cases with diagnostic dilemma. Here we are presenting an unusual prostate cancer case, status post radical prostatectomy, with heterogenous uptake in osseous lesions on 68Ga-PSMA PET/CT scan and low PSA values. He was referred for further evaluation with 18F-FDG PET/CT scan, revealing widely metastatic lesions in bone and liver, in addition to mildly avid recurrence in prostatectomy surgical bed and also metastasis in the spleen.

A Prospective Multicenter Analysis of Mobile Stroke Unit Cost-Effectiveness.

Objective: Given the high disease and cost burden of ischemic stroke, evaluating the clinical efficacy and cost-effectiveness of new approaches to prevent and treat ischemic stroke is critical. Effective ischemic stroke management depends on timely administration of thrombolytics after stroke onset. This study evaluates the cost-effectiveness associated with the use of mobile stroke units (MSUs) to expedite tissue plasminogen activator (tPA) administration, as compared with standard management through emergency medical services (EMS).

Prognostic Significance of Recurrence and Timing of Recurrence on Survival Among Patients with Early-Stage Hepatocellular Carcinoma in U.S. Clinical Practice.

Background: Many patients with hepatocellular carcinoma (HCC) experience recurrence after curative-intent resection or ablation, with a poor prognosis. Real-world patterns of recurrence and the prognostic significance of early recurrence in U.S.

Diuretic efficiency of a single dose of subcutaneous versus oral furosemide after heart failure hospitalization across diuretic resistance strata: A pilot randomized controlled trial.

Aims: Diuretic resistance (DR) in heart failure (HF) is associated with worse outcomes. Furoscix®, a self-administered subcutaneous (sc) furosemide injection administered via on-body infusor, is approved for HF congestion relief. However, its efficacy in patients with DR post-HF hospitalization remains unknown.

Midterm survival, clinical, and hemodynamic outcomes of a novel mechanical mitral valve prosthesis.

Objective: To evaluate the midterm survival, clinical, and hemodynamic outcomes of the On-X mechanical mitral valve, based on the 5-year results of the Prospective Randomized On-X Anticoagulation Clinical Trial (PROACT).

Method: PROACT Mitral was a multicenter study evaluating 401 patients who underwent mitral valve replacement (MVR) with either Standard or Conform-X On-X mitral valves, comparing low-dose and standard-dose warfarin. Here we report prespecified secondary outcomes of survival, New York Heart Association (NYHA) functional classification, and valve hemodynamics as assessed by core lab-adjudicated echocardiography at 1, 3, and 5 years in the pooled population.

Development and Validation of Algorithms to Identify Individuals With Cutaneous Lupus From Healthcare Databases.

Background: There are no validated methods to identify individuals with cutaneous lupus erythematosus (CLE) from large databases including claims data and electronic health records, severely limiting the study of the epidemiology of this disease.

Objectives: To develop and validate accurate algorithms to identify individuals with CLE from healthcare records.

Methods: Twelve case-finding algorithms were developed based on the International Classification of Diseases (ICD)-10 diagnosis codes, provider specialty, and medication prescription data.

Assessing the generalizability of a National Burn Database to the United States pediatric burn injury population.

Background: A national database is used to evaluate pediatric burn survivor outcomes, but the generalizability to the United States pediatric burn injury population is unclear, as only 60% of enrollees are U.S. residents.

Barriers to Medication Adherence in People Living With Epilepsy.

Background And Objectives: Epilepsy affects approximately 1.2% of the US population, resulting in 3.4 million Americans with active epilepsy.

NFE2L2 and SLC25A39 drive cuproptosis resistance through GSH metabolism.

Cuproptosis is a recently discovered form of regulated cell death triggered by mitochondrial copper accumulation and proteotoxic stress. Here, we provide the first evidence that glutathione (GSH), a major non-protein thiol in cells, acts as a cuproptosis inhibitor in pancreatic ductal adenocarcinoma (PDAC) cells. Mechanistically, GSH inhibits cuproptosis by chelating copper, contrasting its role in blocking ferroptosis by inhibiting lipid peroxidation.

Evaluating the impact of liver vasculature model complexity for estimating dose to circulating blood during radiotherapy.

Purpose: To assess the impact of liver model complexity on the estimated radiation dose to circulating blood during radiotherapy.

Methods: Six hepatocellular carcinoma patients were selected covering a range of clinical treatment volume (CTV) sizes and locations. Photon and proton treatment plans were generated for each patient.

Presentation, Treatment, and Survival Among Asians With Gastric Cancer.

Introduction: In aggregate, Asian patients have a higher incidence and mortality from gastric cancer (GC) than Non-Hispanic White (NHW) patients. However, there is a lack of data regarding outcomes among Asian-American subpopulations with GC.

Methods: The National Cancer Database was used to identify patients with GC between 2004 and 2020.

Stability of the polarization agent AsymPolPOK in intact and lysed mammalian cells.

Dynamic nuclear polarization (DNP) solid-state NMR enables detection of proteins at endogenous concentrations in cells through sensitivity enhancement from nitroxide biradical polarization agents. AsymPolPOK, a novel water-soluble asymmetric nitroxide biradical, offers superior sensitivity and faster build-up times compared to existing agents like AMUPol. Here, we characterize AsymPolPOK in mammalian HEK293 cells, examining its cellular distribution, reduction kinetics, and DNP performance.

Cigarette Smoking, Smoking Cessation, and Heart Failure Subtypes: Insights From the Jackson Heart Study.

Background: Cigarette smoking has been associated with incident heart failure (HF). However, the association between cigarette smoking and smoking cessation with HF subtypes has not been well elucidated, particularly among Black people.

Methods And Results: We investigated 4189 (never smoker n=2934, former smoker n=761, current smoker n=464) Black participants (mean age 54 years, 64% women) without a history of HF or coronary heart disease at baseline in the Jackson Heart Study.

Improving the Theranostic Potential of Magnetic Nanoparticles by Coating with Natural Rubber Latex for Ultrasound, Photoacoustic Imaging, and Magnetic Hyperthermia: An In Vitro Study.

Background/objectives: Magnetic nanoparticles (MNPs) have gained attention in theranostics for their ability to combine diagnostic imaging and therapeutic capabilities in a single platform, enhancing targeted treatment and monitoring. Surface coatings are essential for stabilizing MNPs, improving biocompatibility, and preventing oxidation that could compromise their functionality. Natural rubber latex (NRL) offers a promising coating alternative due to its biocompatibility and stability-enhancing properties.

Management of Fracture-Related Infection in Conflict Zones: Lessons Learned from Medical Missions to Gaza.

: Fracture-related infections (FRIs) are a significant complication in conflict zones, where limited resources and damaged infrastructure complicate orthopedic care. : This study retrospectively reviews the management of FRIs during medical missions to Gaza from April to July 2024. : Among 135 patients treated for war-related fractures, 30% were identified with suspected FRIs, which were primarily following explosive injuries.

RNAi Knockdown of in Maternal Expression of Prader-Willi Syndrome Genes.

Background/objectives: Euchromatic histone lysine methyltransferase 2 (EHMT2, also known as G9a) is a mammalian histone methyltransferase that catalyzes the dimethylation of histone 3 lysine 9 (H3K9). On human chromosome 15, the parental-specific expression of Prader-Willi Syndrome (PWS)-related genes, such as and , are regulated through the genetic imprinting of the PWS imprinting center (PWS-IC). On the paternal allele, PWS genes are expressed whereas the epigenetic maternal silencing of PWS genes is controlled by the EHMT2-mediated methylation of H3K9 in PWS-IC.
