Adequate distinction between malnutrition, starvation, cachexia and sarcopenia is important in clinical care. Despite the overlap in physical characteristics, differences in etiology have therapeutical and prognostic implications. We aimed to determine whether dietitians in selected European countries have ‘proper knowledge’ of malnutrition, starvation, cachexia and sarcopenia, and use terminology accordingly.

The aging population faces two conditions that threaten healthy aging: high fat mass (obesity) and low muscle mass and function (sarcopenia). The combination of both—referred to as sarcopenic obesity—synergistically increases the risk of adverse health outcomes. The two conditions often co-occur because they reinforce each other and share common etiologies, including poor nutrition and inactivity. All aging people are at risk of gaining weight and losing muscle mass and could benefit from improvements in physical activity, exercise and dietary intake. one specific window of opportunity is during the transient time of retirement, as older adults already need to restructure their daily activities. It is key to change lifestyle behavior in a sustainable manner, providing scientifically proven, personalized, and acceptable principles that can be integrated in daily life. Health technologies (e.g., applications) can provide promising tools to deliver personalized and appealing lifestyle interventions to a large group of people while keeping health care costs low. Several studies show that health technologies have a strong positive effect on physical activity, exercise and dietary intake. Specifically, health technology is increasingly applied to older people, although strong evidence for long term effects in changing lifestyle behavior is generally lacking. Concluding, technology could play an important role in the highly warranted prevention of sarcopenic obesity in older adults. Although health technology seems to be a promising tool to stimulate changes in physical activity, exercise and dietary intake, studies on long lasting effects and specifically targeted on older people around the time of retirement are warranted.

Om inzicht te krijgen in spierveroudering is genexpressie gemeten in vastus lateralis biopten van jonge en oude mannen en vrouwen. We vonden dat tijdens het ouder worden bij beide geslachten dezelfde categorieën genen in spieren worden aan- en uitgeschakeld (“gereguleerd”); de mate van deze zogenaamde differentiële expressie was echter geslachtsspecifiek. Bij mannen was oxidatieve fosforylering het meest in het oog springende proces, en bij vrouwen was dit celgroei gemedieerd door AKT-signalering. De conclusie is dat dezelfde processen zijn geassocieerd met skeletspierveroudering bij mannen en vrouwen, maar dat de differentiële expressie van die processen geslachtsspecifiek is.
