Predicting the drift of small cetaceans stranded along the Atlantic coast of the Iberian Peninsula: Parametrization of the MOTHY drift model.

Marine mammal populations, particularly the common dolphin Delphinus delphis in the North-East Atlantic, play an essential role as indicators of ecosystem health. Effective monitoring of these populations is essential for assessing anthropogenic impacts, especially in the context of current threats such as fisheries bycatch. The MOTHY drift model, initially designed for oil spills and then adapted to carcass drift, is being used in part of the North East Atlantic (Bay of Biscay, English Chanel, and North Sea) to estimate the bycatch mortality of common dolphins.

Work-related stress assessment in an emergency department in French Guiana.

Background: In emergency departments (EDs), the staff continually face stressful situations requiring staff to adopt various coping strategies.

Aims: The study aimed to assess work-related stress in ED during the COVID-19 outbreak.

Method: The study was a monocentric investigation based on a questionnaire survey that elicits general information and uses the Karasek model to analyse the data.

The stranding anomaly as population indicator: the case of harbour porpoise Phocoena phocoena in North-Western Europe.

Ecological indicators for monitoring strategies are expected to combine three major characteristics: ecological significance, statistical credibility, and cost-effectiveness. Strategies based on stranding networks rank highly in cost-effectiveness, but their ecological significance and statistical credibility are disputed. Our present goal is to improve the value of stranding data as population indicator as part of monitoring strategies by constructing the spatial and temporal null hypothesis for strandings.

Pulpal effects of enamel ablation with a microsecond pulsed lambda = 9.3-microm CO2 laser.

Background And Objectives: In vitro studies have shown that CO2 lasers operating at the highly absorbed 9.3 and 9.6-microm wavelengths with a pulse duration in the range of 10-20-microsecond are well suited for the efficient ablation of enamel and dentin with minimal peripheral thermal damage.

Moderate and chronic hemodynamic overload of sheep atria induces reversible cellular electrophysiologic abnormalities and atrial vulnerability.

Objectives: The aim of this study was to evaluate the myocardial consequences of a chronic volume overload of the left atrium (LA).

Background: Atrial dilation is a major risk factor for atrial fibrillation (AF), but the underlying mechanisms are poorly understood.

Methods: A left-right aorto-pulmonary artery shunt (APS) was created in sheep.

Minimally invasive patent ductus arteriosus occlusion in 5 dogs.

Objective: To report a technique for minimally invasive occlusion of patent ductus arteriosus (PDA) and outcome in 5 dogs.

Study Design: Clinical cases.

Animals: Five, 4-6-month-old, dogs with PDA.
