Diagnosis and management of acute hyperkalaemia

Abstract Hyperkalaemia is a common and potentially life threatening electrolyte abnormality because of its association with malignant cardiac arrhythmias and sudden cardiac arrest. This condition is frequently encountered across acute and chronic care settings and disproportionat...

Novel Use of Penile Ultrasound in the Evaluation of Patients With Adult Acquired Buried Penis

Adult acquired buried penis (AABP) disease is a risk factor for penile cancer. For a subset of patients, the severity of their disease precludes complete physical examination of the penile shaft due to the inability to exhume the penis. Thus, providers are unable to identify peni...

Pharmacokinetic and pharmacodynamic sub-study of trans-arterial vs. intravenous gemcitabine in the TIGeR-PaC phase 3 clinical trial

Abstract Purpose Localized intra-arterial delivery of gemcitabine (IAG) may provide advantages in terms of increased tissue concentration and decreased systemic dosing. We hypothesized IAG may result in decreased systemic gemcitabine concentration and associated side effects due...

A uniform sub-three-fifths bound for exceptional abc triples

GPT 5.6 Sol discovered the result and proof presented in this paper. We establish a new uniform upper bound for the number of exceptional abc triples throughout the full subcritical range. The proof combines an anatomic decomposition with Fourier analysis, geometry-of-numbers est...

The hematology workforce in the United States: past, present, and strategies for the future

From 2017-2021, the American Society of Hematology (ASH) completed the largest study ever conducted of the hematology workforce in the United States (US). The study highlighted a deficit in the classical hematology (CH) workforce: despite very high CH clinical volumes encountered...

Focal Therapy for Prostate Cancer

This retrospective study uses data from the National Cancer Database to examine patterns and temporal trends in use of focal therapy for prostate cancer in US cancer centers; characterize inappropriate use in low-, high-, or very–high-risk disease; and describe intermediate-risk...

Discontinuous Peripheral Punctate Echogenic Foci in Thyroid Nodules: A New Sonographic Pattern Suggestive of Papillary Carcinoma

Background: Ultrasound risk stratification systems for thyroid nodules worldwide describe different types of echogenic foci, including punctate echogenic foci (microcalcifications), coarse internal calcifications, and peripheral (rim) calcifications (complete or incomplete), with...

Rural-Urban Disparities in Contemporary Systemic Therapy for Advanced Prostate Cancer

This cross-sectional study examines the associations of rural-urban residence and race with receipt of systemic therapy for advanced prostate cancer.

A dependency map enhanced with next-generation 3D cancer models

Despite advances in precision oncology, effective personalized treatments are still lacking for most patients with cancer1. The Cancer Dependency Map (DepMap) accelerates this field by systematically identifying cancer vulnerabilities in diverse preclinical models. Data from over...

Aldose reductase as a regulator of ocular pathology: Mechanisms and therapeutic potential.

Aldose reductase (AR), the rate-limiting enzyme of the polyol pathway, converts glucose to sorbitol using NADPH and becomes markedly overactive under hyperglycemic conditions. Its widespread expression in ocular tissues links AR to numerous eye disorders through sorbitol accumula...

Clinical Meaningfulness and Improvement Thresholds of Myositis Core Set Measures: Association with Patient-Reported Outcomes

Objective The study aimed to evaluate the clinical meaningfulness and improvement thresholds of the myositis core set measures (CSMs) of disease activity in idiopathic inflammatory myopathies (IIM), emphasizing associations with patient-reported outcome measures (PROMs). Methods...
