Gastric Ultrasound in the Management of Emergency Department Patients with Upper Gastrointestinal Bleeding: A Case Series and Sonographic Technique.

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: An Emergency Medicine Review.

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.

Echocardiographic diagnosis and clinical implications of wide-open tricuspid regurgitation for evaluating right ventricular dysfunction in the emergency department.

The tricuspid regurgitation pressure gradient (TRPG) reflects the difference in pressure between the right ventricle and right atrium (ΔP). 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.

Is pulmonary hypertension protective against cardiac tamponade? A systematic review.

The presence of pulmonary hypertension (PH) may affect whether cardiac tamponade physiology develops from a pericardial effusion. 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.

Aqua-bis-(2,2'-bi-pyridine-κ,')(isonicotinamide-κ)ruthenium(II) bis-(trifluoromethanesulfonate).

In the title complex, [Ru(CHN)(CHNO)(HO)](CFSO), the central Ru atom is sixfold coordinated by two bidentate 2,2'-bi-pyridine, an isonic-otinamide ligand, and a water mol-ecule in a distorted octa-hedral environment with tri-fluoro-methane-sulfonate ions completing the outer coordination sphere of the complex. Hydrogen bonding involving the water mol-ecule and weak π-π stacking inter-actions between the pyridyl rings in adjacent mol-ecules contribute to the alignment of the complexes in columns parallel to the axis.
