Surgical management of ossifying fibroma in a 9-year-old Hungarian Vizsla: a case report and review of the literature.

Ossifying fibroma (OF) is a rare, benign fibro-osseous neoplasm that primarily originates from membranous bones. While most frequently documented in equines, OF has also been reported in other species, including dogs, though it remains uncommon. The condition poses significant diagnostic challenges due to its ambiguous presentation, often requiring differentiation from other benign and malignant intraosseous lesions.

Protocol and Statistical Analysis Plan for the Randomized Trial of Sedative Choice for Intubation (RSI).

Background: Emergency tracheal intubation is a common and high-risk procedure. Ketamine and etomidate are sedative medicines commonly used to induce anesthesia for emergency tracheal intubation, but whether the induction medication used affects patient outcomes is uncertain.

Research Question: Does the use of ketamine for induction of anesthesia decrease the incidence of death among adults undergoing emergency tracheal intubation, compared to the use of etomidate?

Study Design And Methods: The Randomized trial of Sedative choice for Intubation (RSI) is a pragmatic, multicenter, unblinded, parallel-group, randomized trial being conducted in 14 sites (6 emergency departments and 8 intensive care units) in the United States.

Pain Perception Threshold in Young High-Altitude Natives After Acute Exposure to Severe Hypoxic Conditions.

Previous studies indicate that individuals at high altitudes have a lower pain threshold than those living at sea level. This study evaluates the differences in pain perception among young people living at an altitude of 3800 m and after acute exposure to a severe hypoxic environment at more than 5100 m. Fourteen people (BMI of 22.

A mind-body resilience intervention for emotional distress in cardiac arrest survivors and their informal caregivers - Recovering together after cardiac arrest: Protocol for an open pilot trial.

Background: Chronic emotional distress among cardiac arrest (CA) survivors and their caregivers is prevalent and worsens quality of life and recovery. Interventions to prevent chronic distress post-CA are needed. We developed (RT-CA), an intervention to increase resiliency in CA survivor-caregiver dyads (pairs).

The use of an automatic remote weight management system to track treatment response, identified drugs supply shortage and its consequences: A pilot study.

Objective: The objective of this pilot study is to evaluate the feasibility of using an automatic weight management system to follow patients' response to weight reduction medications and to identify early deviations from weight trajectories.

Methods: The pilot study involved 11 participants using Semaglutide for weight management, monitored over a 12-month period. A cloud-based, Wi-Fi-enabled remote weight management system collected and analyzed daily weight data from smart scales.

That men should put an enemy in their mouths to steal away their brains: Reconsidering the origins of model psychosis.

The promises of the Prozac century have fallen short; the number of novel, therapeutically significant medications successfully completing development shrinks every year; and the demand for better treatments constantly grows. Answering these hardships is a renewed optimism concerning the efficacy of controlled psychedelic therapy, a that has seen the resurgence of a familiar concept: intoxication as model psychosis. And yet, little has been made of where this peculiar idea originates.

Late-Stage Minimal Labeling of Peptides and Proteins for Real-Time Imaging of Cellular Trafficking.

The cellular uptake routes of peptides and proteins are complex and diverse, often handicapping therapeutic success. Understanding their mechanisms of internalization requires chemical derivatization with approaches that are compatible with wash-free and real-time imaging. In this work, we developed a new late-stage labeling strategy for unprotected peptides and proteins, which retains their biological activity while enabling live-cell imaging of uptake and intracellular trafficking.

A conceptual framework for the ethical analysis of moral conflicts in migrant live-in care.

In many industrialized countries, hiring a migrant live-in carer represents a promising solution to support families caring for an older person at home and to avoid institutionalization. Migrant live-in carers live in the household of the person in need of care and provide extensive care and social support. They usually come from geographic areas such as Eastern Europe or Southeast Asia.

Three episodes of basilar tip occlusion necessitating thrombectomies and a vertebral artery sacrifice in a patient with subclavian artery dissection distal to the vertebral artery origin: a case report.

Background: While acute occlusion of the subclavian artery (SCA) proximal to the vertebral artery (VA) origin is an uncommon but recognized cause of embolic stroke, an occlusion distal to the VA is rare and can be easily overlooked.

Case Description: We describe the clinical presentation and evaluation of a previously healthy 56-year-old woman who experienced four life-threatening posterior circulation strokes within 1 month, three of which led to basilar artery (BA) occlusions requiring thrombectomies. Workup revealed an occlusion of the right SCA located less than 1 cm distal to the VA origin.

Towards a standard application of the Reynolds number in studies of aquatic animal locomotion.

Nondimensional groups of measured quantities enable comparison between measurements of animals under different conditions and comparison between species. One of the most used such group is the Reynolds number, which compares inertial and viscous contributions to forces on swimming animals. This group includes two quantities that are chosen by the researcher: a typical length and speed.

One- and two-particle microrheology of soft materials based on optical-flow image analysis.

Particle-tracking microrheology probes the rheology of soft materials by accurately tracking an ensemble of embedded colloidal tracer particles. One-particle analysis, which focuses on the trajectory of individual tracers is ideal for homogeneous materials that do not interact with the particles. By contrast, the characterization of heterogeneous, micro-structured materials or those where particles interact directly with the medium requires a two-particle analysis that characterizes correlations between the trajectories of distinct particle pairs.

Success and failure in establishing national physician databases: a comparison between Canada and Israel.

Physician databases constitute an essential component of health workforce planning. However, while some countries have established functioning national physician databases, others have failed to do so. We compared the healthcare systems of two technologically and economically developed countries, Canada and Israel, which represent cases of respective success and failure in establishing physician databases.

Clinical progress note: Diagnostic approach to dizziness and vertigo.

Dizziness is a common clinical presentation that incurs huge financial costs. It is frequently misdiagnosed due to a wide differential involving both benign (inner ear disease) and serious (stroke) disorders. Traditional frameworks that emphasize symptom quality (dizziness/lightheadedness/vertigo) lack diagnostic utility.

Precision in Liver Diagnosis: Varied Accuracy Across Subgroups and the Need for Variable Thresholds in Diagnosis of MASLD.

Background And Aims: The performance of non-invasive liver tests (NITs) is known to vary across settings and subgroups. We systematically evaluated whether the performance of three NITs in detecting advanced fibrosis in patients with metabolic dysfunction-associated steatotic liver disease (MASLD) varies with age, sex, body mass index (BMI), type 2 diabetes mellitus (T2DM) status or liver enzymes.

Methods: Data from 586 adult LITMUS Metacohort participants with histologically characterised MASLD were included.

CaML: Chemistry-informed machine learning explains mutual changes between protein conformations and calcium ions in calcium-binding proteins using structural and topological features.

Proteins' flexibility is a feature in communicating changes in cell signaling instigated by binding with secondary messengers, such as calcium ions, associated with the coordination of muscle contraction, neurotransmitter release, and gene expression. When binding with the disordered parts of a protein, calcium ions must balance their charge states with the shape of calcium-binding proteins and their versatile pool of partners depending on the circumstances they transmit. Accurately determining the ionic charges of those ions is essential for understanding their role in such processes.

Inoculation reduces social media engagement with affectively polarized content in the UK and US.

The generation and distribution of hyper-partisan content on social media has gained millions of exposure across platforms, often allowing malevolent actors to influence and disrupt democracies. The spread of this content is facilitated by real users' engaging with it on platforms. The current study tests the efficacy of an 'inoculation' intervention via six online survey-based experiments in the UK and US.

A first principles study of convection cells to shear flow instability in 2D Yukawa liquids driven by Reynolds stress.

The stability of kinetic-level convection cells (wherein the magnitude of macroscopic and microscopic velocities are of same order) is studied in a two-dimensional Yukawa liquid under the effect of microscopic velocity perturbations. Our numerical experiments demonstrate that for a given system aspect ratio β viz., the ratio of system length [Formula: see text] to its height [Formula: see text] and number of convective rolls initiated [Formula: see text], the fate of the convective cells is decided by [Formula: see text].

Preoperative Cardiac Assessment for Coronary Artery Disease: From Symptoms to Angiography.

Although cardiovascular anesthesiologists play a role in the multidisciplinary heart team, they are generally not involved prior to the diagnosis of coronary artery disease. This work was designed to broadly cover the factors influencing decision-making when proceeding with coronary angiography in a patient with suspected coronary artery disease. The authors cover the principles, rationale, benefits, and downsides of common tests involved.
