Solitary plasmacytomas are localized single tumors of monoclonal plasma cells that occur in two variants: solitary plasmacytoma of bone and extraosseous plasmacytoma. Solitary plasmacytoma of bone accounts for only 1%-2% of plasma cell lesions, and extraosseous plasmacytoma is also approximately 1%. These are both very uncommon at the skull base.

Objectives: To assess the contemporary malignancy rate in isolated de novo red patches in the bladder and associated risk factors for better selection of red patch biopsy.

Patients: Patients from the IDENTIFY dataset; Patients referred to secondary care with suspected urinary tract cancer and found to have isolated de novo red patches on cystoscopy.

Methods: We reported the unadjusted cancer prevalence in isolated de novo red patches that were biopsied; multivariable logistic regression was used to explore cancer-associated risk factors including age, sex, smoking, type of haematuria, LUTS, UTIs and a suspicious-looking red patch (as reported by the cystoscopist).

Patient-based scenario-driven usability tests are routinely created for health information technology and clinical decision support evaluations. Due to low clinician awareness of sepsis, a study was undertaken to understand clinician performance and preference of different display types for sepsis clinical decision support through multi-centered usability testing. Patient-based clinical scenarios were created to mimic the environment in which providers would interact with clinical decision support.

A Narrative Persuasion Approach to Promoting COVID-19- Related Policy Support.

J Health Commun

January 2025

School of Criminal Justice, Forensic Science, and Security, University of Southern Mississippi, Hattiesburg, Mississippi, USA.

Communication scholars warn against focusing on individual behaviors when discussing health issues, arguing that doing so can reduce affect and policy support. Although COVID-19 outcomes are linked to structural barriers to treatment, policy interventions appear to improve outcomes for vulnerable groups. Thus, strategic messages must promote public understanding of social determinants and policy support related to COVID-19.

Population variability across geographical ranges: perspectives and challenges.

Proc Biol Sci

January 2025

Department of Biological Sciences, University of South Carolina, Columbia, SC 29208, USA.

Populations fluctuate over time and across geographical space, and understanding how different factors contribute to population variability is a central goal in population ecology. There is a particular interest in identifying trends of population variability within geographical ranges as population densities of species can fluctuate substantially across geographical space. A common assumption is that populations vary more near species geographical range edges because of unsuitable environments and higher vulnerability to environmental variability in these areas.

Background: Quadriceps dysfunction is ubiquitous after anterior cruciate ligament (ACL) reconstruction (ACLR). Addressing quadriceps dysfunction is crucial to improve function, reduce the reinjury risk, and maintain long-term knee health. While deficits specific to the quadriceps are well documented, less is known about the effect of an ACL injury on other lower extremity muscle groups.

Arthritis, a chronic inflammatory condition linked to cardiovascular disease (CVD) and bone fracture, is more frequent among military veterans and postmenopausal women. This study examined correlates of arthritis and relationships of arthritis with risks of developing CVD, bone fractures, and mortality among postmenopausal veteran and non-veteran women. We analyzed longitudinal data on 135,790 (3,436 veteran and 132,354 non-veteran) postmenopausal women from the Women's Health Initiative who were followed-up for an average of 16 years between enrollment (1993-1998) and February 17, 2024.

Enhanced phosphorus weathering contributed to Late Miocene cooling.

Nat Commun

January 2025

Centre for Marine Magnetism (CM2), Department of Ocean Science and Engineering, Southern University of Science and Technology, Shenzhen, China.

Late Miocene climate evolution provides an opportunity to assess Earth's climate sensitivity to carbon cycle perturbation under warmer-than-modern conditions. Despite its relevance for understanding the climate system, the driving mechanisms underlying profound climate and carbon cycle changes - including the enigmatic Late Miocene cooling from 7 to 5.4 million years ago - remain unclear.

Structure and function of a near fully-activated intermediate GPCR-Gαβγ complex.

Nat Commun

January 2025

Department of Molecular Biosciences, University of South Florida, 4202 E Fowler Ave, Tampa, FL, 33620, USA.

Unraveling the signaling roles of intermediate complexes is pivotal for G protein-coupled receptor (GPCR) drug development. Despite hundreds of GPCR-Gαβγ structures, these snapshots primarily capture the fully activated complex. Consequently, the functions of intermediate GPCR-G protein complexes remain elusive.

RNA N6-methyladenosine (m6A) plays diverse roles in RNA metabolism and its deregulation contributes to tumor initiation and progression. Clear cell renal cell carcinoma (ccRCC) is characterized by near ubiquitous loss of followed by mutations in epigenetic regulators , , and . Mutations in , a histone H3 lysine 36 trimethylase (H3K36me3), are associated with reduced survival, greater metastatic propensity, and metabolic reprogramming.

Background: Larsucosterol is a DNA methyltransferase inhibitor in development for alcohol-associated hepatitis (AH), a disease for which there is no approved therapy.

Methods: In this phase 2b trial, patients with severe AH were randomly assigned 1:1:1 to receive 30 mg or 90 mg of larsucosterol or placebo; a second dose was administered after 72 hours if the patient remained hospitalized. All patients received supportive care as determined by investigators.

Background And Aims: An expansion of fat mass is an integral feature of patients with heart failure and preserved ejection fraction (HFpEF). While body mass index (BMI) is the most common anthropometric measure, a measure of central adiposity-the waist-to-height ratio (WHtR)-focuses on body fat content and distribution; is not distorted by bone or muscle mass, sex, or ethnicity; and may be particularly relevant in HFpEF.

Methods: The PARAGON-HF trial randomized 4796 patients with heart failure and ejection fraction ≥45% to valsartan or sacubitril/valsartan.

Under climate change, ecosystems are experiencing novel drought regimes, often in combination with stressors that reduce resilience and amplify drought's impacts. Consequently, drought appears increasingly likely to push systems beyond important physiological and ecological thresholds, resulting in substantial changes in ecosystem characteristics persisting long after drought ends (i.e.

Aims: Early identification and management of worsening heart failure (HF) is necessary to prevent disease progression and hospitalizations. The ALLEVIATE-HF (Algorithm Using LINQ Sensors for Evaluation and Treatment of Heart Failure) trial is a prospective, randomized, controlled, double-blind, multicentre trial that aims to assess the safety and efficacy of using the Reveal LINQ™ insertable cardiac monitor (ICM) in patients with HF to continuously monitor and evaluate HF risk status and guide timely interventions.

Methods: The ICM algorithm uses parameters derived from electrocardiogram (atrial fibrillation [AF], ventricular rate during AF, heart rate variability, and night heart rate), three-axis accelerometer (patient activity duration), and subcutaneous bioimpedance (fluid volume, respiration rate).

As an emerging toxic recreational drug, kratom use has been associated with a range of adverse effects, but reports of structural changes in the central nervous system are rare. We report a case of a young man in his 20s with a history of anxiety and depression who presented with an altered mental status and anterograde and retrograde amnesia following kratom use. His labs showed elevated alanine aminotransferase and ammonia levels, and his MRI revealed bilateral hippocampal T2 hyperintensity signal changes.
