Total occlusion of abdominal aorta: still a deadly event in the very elderly.

Associated morbidity and mortality remain substantial with high rates of limb loss, acute renal failure, rhabdomyolysis, and death.

Cumulative impact assessment for ecosystem-based marine spatial planning.

Claims for ocean space are growing while marine ecosystems suffer from centuries of insufficient care. Human pressures from runoff, atmospheric emissions, marine pollution, fishing, shipping, military operations and other activities wear on habitats and populations. Ecosystem-based marine spatial planning (MSP) has emerged worldwide as a strategic instrument for handling conflicting spatial claims among competing sectors and the environment.
