Background: Gastrointestinal bleeding (GIB) is a common condition in the emergency department (ED) with high incidence and mortality.
Objectives: Very early risk stratification of GIB patients can sometimes be a challenge. The decision to intubate these patients is multifactorial and requires careful consideration.

Cardiac point-of-care ultrasound (POCUS) can make critical diagnoses and monitor the response to interventions. In contrast with consultative echocardiography, cardiac POCUS serves to answer a specific clinical question. This imaging modality can be used to evaluate for left ventricular systolic and diastolic dysfunction, pericardial effusion and tamponade, acute and chronic right ventricular dysfunction, valvular dysfunction, and cardiac activity in cardiac arrest.

Its estimation by echocardiography correlates well with that obtained using right-heart catheterization. An elevated TRPG is an important marker for identifying right ventricular dysfunction in both the acute and chronic settings.

Specifically, the increased intracardiac pressure and right ventricular hypertrophy associated with PH would seemingly increase the intrapericardial pressure threshold at which the right-sided chambers collapse. In this systematic review, we examined the impact of PH on the incidence, in-hospital and long-term mortality, and echocardiographic findings of patients with cardiac tamponade.

Early diagnosis and goal-directed management improve outcomes and survival. Both conditions share several echocardiographic findings of right ventricular dysfunction.

Objective: This review incorporates available evidence to clarify misconceptions regarding the clinical presentation, while providing an in-depth expert guide on bedside echocardiography.
Introduction: Evidence supports an ultrasound-guided approach in patients with difficult vascular access. Prior research on teaching ultrasound-guided intravenous access has included only small groups of first- and second-year medical students.
Methods: We enrolled fourth-year medical students in our teaching module.
Background: Nonablative fractional photothermolysis has revolutionized the way we treat a number of common skin conditions with laser technology.
Objective: A comprehensive guide is needed for clinicians using this technology to treat specific skin conditions in various skin types.
Materials And Methods: Recommendations were made from a recent round table discussion among experienced physicians and a review of recent literature findings.
The Neuroscience Information Framework (NIF), developed for the NIH Blueprint for Neuroscience Research and available at http://nif.nih.gov and http://neurogateway.
View Article and Find Full Text PDFWith support from the Institutes and Centers forming the NIH Blueprint for Neuroscience Research, we have designed and implemented a new initiative for integrating access to and use of Web-based neuroscience resources: the Neuroscience Information Framework. The Framework arises from the expressed need of the neuroscience community for neuroinformatic tools and resources to aid scientific inquiry, builds upon prior development of neuroinformatics by the Human Brain Project and others, and directly derives from the Society for Neuroscience's Neuroscience Database Gateway. Partnered with the Society, its Neuroinformatics Committee, and volunteer consultant-collaborators, our multi-site consortium has developed: (1) a comprehensive, dynamic, inventory of Web-accessible neuroscience resources, (2) an extended and integrated terminology describing resources and contents, and (3) a framework accepting and aiding concept-based queries.
