Carbonyl sulfide (COS) emissions in two agroecosystems in central France.

Carbonyl sulfide (COS) fluxes simulated by vegetation and soil component models, both implemented in the ORCHIDEE land surface model, were evaluated against field observations at two agroecosystems in central France. The dynamics of a biogenic process not yet accounted for by this model, i.e.

Why Won't Emergency Physicians Discharge Patients With a Low HEART Score From an Observation Unit Without Further Evaluation?

Background: The History, Electrocardiogram, Age, Risk Factors, Troponin (HEART) score is a prospectively validated risk stratification tool for patients presenting to the emergency department (ED) with chest pain. Data demonstrate that patients with low HEART scores (0-3) can be safely discharged from the ED. ED physicians, however, may be reluctant to discharge patients based on the score.

A top-down approach of sources and non-photosynthetic sinks of carbonyl sulfide from atmospheric measurements over multiple years in the Paris region (France).

Carbonyl sulfide (COS) has been proposed as a proxy for carbon dioxide (CO2) taken up by plants at the leaf and ecosystem scales. However, several additional production and removal processes have been identified which could complicate its use at larger scales, among which are soil uptake, dark uptake by plants, and soil and anthropogenic emissions. This study evaluates the significance of these processes at the regional scale through a top-down approach based on atmospheric COS measurements at Gif-sur-Yvette (GIF), a suburban site near Paris (France).

A 90-second magnetocardiogram using a novel analysis system to assess for coronary artery stenosis in Emergency department observation unit chest pain patients.

Background: Magnetocardiography (MCG) has been shown to non-invasively detect coronary artery stenosis (CAS). Emergency department (ED) patients with possible acute coronary syndrome (ACS) are commonly placed in an observation unit (OU) for further evaluation. Our objective was to compare a novel MCG analysis system with stress testing (ST) and/or coronary angiography (CA) in non-high risk EDOU chest pain patients.

Use of Extracorporeal Membrane Oxygenation and Surgical Embolectomy for Massive Pulmonary Embolism in the Emergency Department.

Background: Massive pulmonary embolism (PE) carries significant morbidity and mortality with current standard of care modalities.

Case Report: We present the case of a 63-year-old male status post abdominal surgery 2 weeks before presenting to the emergency department with a massive pulmonary embolism and subsequent acute cardiopulmonary failure. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Here we describe a case of extracorporeal membrane oxygenation (ECMO) deployed in the emergency department as a bridge to embolectomy to successfully treat massive pulmonary embolism.
