Randomized Controlled TrialInsufficient activation of autophagy allows cellular damage to accumulate in critically ill patients.
Responses to critical illness, such as excessive inflammation and hyperglycemia, may trigger detrimental chain reactions that damage cellular proteins and organelles. Such responses to illness contribute to the risk of (nonresolving) multiple organ dysfunction and adverse outcome. ⋯ Insufficient autophagy in prolonged critical illness may cause inadequate removal of damaged proteins and mitochondria. Such incomplete clearance of cellular damage, inflicted by illness and aggravated by hyperglycemia, could explain lack of recovery from organ failure in prolonged critically ill patients. These data open perspectives for therapies that activate autophagy during critical illness.

Randomized Controlled TrialDifferential acylated ghrelin, peptide YY3-36, appetite, and food intake responses to equivalent energy deficits created by exercise and food restriction.
Acute energy deficits imposed by food restriction increase appetite and energy intake; however, these outcomes remain unchanged when energy deficits are imposed by exercise. ⋯ These findings suggest a mediating role of acylated ghrelin and PYY(3-36) in determining divergent feeding responses to energy deficits imposed by food restriction and exercise.

Randomized Controlled Trial Multicenter StudyEffects of denosumab treatment and discontinuation on bone mineral density and bone turnover markers in postmenopausal women with low bone mass.
Denosumab treatment for 24 months increased bone mineral density (BMD) and reduced bone turnover markers (BTM) in postmenopausal women. ⋯ In postmenopausal women with low BMD, the effects of 60 mg denosumab treatment for 24 months on BMD and BTM are reversible upon discontinuation, reflecting its biological mechanism of action. Residual BMD measurements remained above those of the group previously treated with placebo.
