Agreement between rectus femoris muscle thickness by ultrasound and skeletal muscle mass by bio-electrical impedance analysis: a pilot study

Nijholt, Willemke; Sealy, Martine (Healthy Ageing, Allied Health Care And Nursing); van der Schans, Cees; Hobbelen, Hans (Ageing And Allied Health Care); Jager-Wittenaar, Harriët (Malnutrition And Healthy Ageing); Rodenburg, Iris

Rationale: Sarcopenia is a major problem and is common in community-dwelling elderly. In daily practice, there is need for low cost and easily assessable measurement tools to assess depletion of skeletal muscle (SM) mass, for example as one of the indicators of sarcopenia. Bio-electrical impedance analysis …

The reliability and validity of ultrasound to quantify muscles in older adults

Nijholt, Willemke; Scafoglieri, Aldo; Jager-Wittenaar, Harriët (Malnutrition And Healthy Ageing); Hobbelen, Hans (Ageing And Allied Health Care); van der Schans, Cees P

This review evaluates the reliability and validity of ultrasound to quantify muscles in older adults. The databases PubMed, Cochrane, and Cumulative Index to Nursing and Allied Health Literature were systematically searched for studies. In 17 studies, the reliability (n = 13) and validity (n = 8) of …

Protein turnover and metabolism in the elderly intensive care unit patient

Phillips, Stuart M.; Dickerson, Roland N.; Moore, Frederick A.; Paddon-Jones, Douglas; Weijs, Peter J. M. (Lectoraat Voeding En Beweging)

Many intensive care unit (ICU) patients do not achieve target protein intakes particularly in the early days following admittance. This period of iatrogenic protein undernutrition contributes to a rapid loss of lean, in particular muscle, mass in the ICU. The loss of muscle in older (aged >60 years) …

Association between computed tomography assessment of skeletal muscle index and muscle attenuation and chemotherapy intolerance in patients with head and neck cancer: preliminary results

Sealy, Martine (Healthy Ageing, Allied Health Care And Nursing); van der Schans, Cees; Jager-Wittenaar, Harriët (Malnutrition And Healthy Ageing); Krijnen, Wim (Statistical Techniques For Applied Research); Roodenburg, Jan; Baracos, Vickie

A higher protein intake is not associated with 5-year change in mid-thigh muscle cross-sectional area by computed tomography in older adults

Verreijen, A.M.; Engberink, M.F.; Brouwer, I.A.; Cawthon, P.M.; Newman, A.B.; Tylavsky, F.A.; Harris, T.B.; Weijs, P.J.M. (Lectoraat Voeding En Beweging); Visser, M.

Rationale: A higher protein intake is suggested to preserve muscle mass during aging, and may therefore reduce the risk for sarcopenia. We explored whether the amount, type (animal/vegetable) and essential amino acid (EAA) composition of protein intake were associated with 5-year change in mid-thigh …

Short-term muscle disuse lowers myofibrillar protein synthesis rates and induces anabolic resistance to protein ingestion.

B.T. Wall; M.L. Dirks; T. Snijders; Jan-Willem van Dijk; M. Fritsch; L.B. Verdijk; Luc van Loon

Disuse leads to rapid loss of skeletal muscle mass and function. It has been hypothesized that short successive periods of muscle disuse throughout the lifespan play an important role in the development of sarcopenia. The physiological mechanisms underlying short-term muscle disuse atrophy remain to …

Unsatisfactory knowledge and use of terminology regarding malnutrition, starvation, cachexia and sarcopenia among dietitians

ter Beek, Lies; Vanhauwaert, Erika; Slinde, Frode; Orrevall, Ylva; Henriksen, Christine; Johansson, Madelene; Vereecken, Carine; Rothenberg, Elisabet; Jager-Wittenaar, Harriët (Malnutrition And Healthy Ageing)

Clinical signs of malnutrition, starvation, cachexia and sarcopenia overlap, as they all imply muscle wasting to a various extent. However, the underlying mechanisms differ fundamentally and therefore distinction between these phenomena has therapeutic and prognostic implications. We aimed to determine …

A high whey protein-, leucine-, and vitamin D-enriched supplement preserves muscle mass during intentional weight loss in obese older adults: a double-blind randomized controlled trial.

Verreijen, Amely M; Verlaan, Sjors; Engberink, Mariëlle F; Swinkels, Sophie; de Vogel-van den Bosch, Johan; Weijs, Peter JM (Lectoraat Voeding En Beweging)

BACKGROUND: Intentional weight loss in obese older adults is a risk factor for muscle loss and sarcopenia. OBJECTIVE: The objective was to examine the effect of a high whey protein-, leucine-, and vitamin D-enriched supplement on muscle mass preservation during intentional weight loss in obese older …

Dietary protein intake in Dutch elderly people

Tieland, Michael (Lectoraat Voeding En Beweging); Borgonjen-Van den Berg, Karin J.; Van Loon, Luc J. C.; de Groot, Lisette C. P. G. M.

INTRODUCTION: Sufficient high quality dietary protein intake is required to prevent or treat sarcopenia in elderly people. Therefore, the intake of specific protein sources as well as their timing of intake are important to improve dietary protein intake in elderly people. OBJECTIVES: to assess the consumption …

Knowledge and practice among dietitians in four Western European countries regarding malnutrition, starvation, cachexia and sarcopenia

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 …
