Does pravastatin suppress matrix metalloproteinase expression and activity in human articular chondrocytes stimulated by interleukin-1β?
Treatment with pravastatin of stimulated human chondrocytes leads to significant down-regulation of selected MMP genes and a non-significant reduction in MMP enzyme activity. Our results provide further evidence that statins may have a role to play in future treatment of disease affecting articular chondrocytes.
Concentric collapse is a somewhat common condition encountered in sleep endoscopy evaluations of PAP alternatives, and cannot be sustainably predicted with anthropometric or sleep assessments. Sleep surgeons should be aware of the possibility of concentric collapse, especially in candidates who are more overweight and have severe sleep apnea. Sleep endoscopy can be useful for providing information about continuous positive airway pressure (CPAP) alternatives or to motivate patient adherence to treatment.
