RESUMEN
Malnutrition in older adults has been recognised as a challenging health concern associated with not only increased mortality and morbidity, but also with physical decline, which has wide ranging acute implications for activities of daily living and quality of life in general. Malnutrition is common and may also contribute to the development of the geriatric syndromes in older adults. Malnutrition in the old is reflected by either involuntary weight loss or low body mass index, but hidden deficiencies such as micronutrient deficiencies are more difficult to assess and therefore frequently overlooked in the community-dwelling old. In developed countries, the most cited cause of malnutrition is disease, as both acute and chronic disorders have the potential to result in or aggravate malnutrition. Therefore, as higher age is one risk factor for developing disease, older adults have the highest risk of being at nutritional risk or becoming malnourished. However, the aetiology of malnutrition is complex and multifactorial, and the development of malnutrition in the old is most likely also facilitated by ageing processes. This comprehensive narrative review summarizes current evidence on the prevalence and determinants of malnutrition in old adults spanning from age-related changes to disease-associated risk factors, and outlines remaining challenges in the understanding, identification as well as treatment of malnutrition, which in some cases may include targeted supplementation of macro- and/or micronutrients, when diet alone is not sufficient to meet age-specific requirements.

The COVID-19 pandemics is posing unprecedented challenges and threats to patients and healthcare systems worldwide. Acute respiratory complications that require intensive care unit (ICU) management are a major cause of morbidity and mortality in COVID-19 patients. Patients with worst outcomes and higher mortality are reported to include immunocompromised subjects, namely older adults and polymorbid individuals and malnourished people in general. ICU stay, polymorbidity and older age are all commonly associated with high risk for malnutrition, representing per se a relevant risk factor for higher morbidity and mortality in chronic and acute disease. Also importantly, prolonged ICU stays are reported to be required for COVID-19 patients stabilization, and longer ICU stay may per se directly worsen or cause malnutrition, with severe loss of skeletal muscle mass and function which may lead to disability, poor quality of life and additional morbidity. Prevention, diagnosis and treatment of malnutrition should therefore be routinely included in the management of COVID-19 patients. In the current document, the European Society for Clinical Nutrition and Metabolism (ESPEN) aims at providing concise guidance for nutritional management of COVID-19 patients by proposing 10 practical recommendations. The practical guidance is focused to those in the ICU setting or in the presence of older age and polymorbidity, which are independently associated with malnutrition and its negative impact on patient survival.

BACKGROUND: Malnutrition is a common problem in patients with digestive disease and is associated with impaired outcome. OBJECTIVE: We investigated the effect of a three-month post-hospital nutritional intervention with high protein and energy supplements on body composition, muscle function and quality of life (QoL) in malnourished GI patients. PATIENTS AND INTERVENTION: Eighty malnourished patients with benign digestive disease were randomized to receive either oral nutritional supplements (ONS) for three months in addition to dietary counselling (DC) (ONS patients) or only dietary counselling (DC patients). METHODS: Nutritional status was determined with the subjective global assessment, body composition by bioelectrical impedance and anthropometry, muscle function with hand-grip strength and peak flow. QoL was assessed by the 36-item short-form questionnaire. RESULTS: Age, body cell mass (BCM), muscle function, gender distribution and QoL did not differ between ONS patients (n=38) and DC patients (n=42) at baseline. Body weight and BCM improved significantly in both groups after three months. However, hand-grip strength (26.1+/-11.3-31.5+/-10.1 kg, p<0.0001) and peak flow (329.2+/-124.0-388.9+/-108.4 l /min, p=0.004) improved only in the ONS patients and remained unchanged in the DC patients. Similarly, all eight scales of the QoL improved in the ONS patients compared with merely three in the DC patients. DC patients experienced significantly more readmissions (n=20) than ONS patients (n=10) during the study period (p=0.041). CONCLUSION: A three month intervention with high protein oral supplements improves outcome in malnourished patients with digestive disease in terms of functional status, QoL and rehospitalization.

This review focuses on the studies investigating the prognostic implications of disease-related malnutrition. Malnutrition is a common problem in patients with chronic or severe diseases. Prevalence of hospital malnutrition ranges between 20% and 50% depending on the criteria used in order to determine malnutrition and the patient's characteristics. Furthermore, nutritional status is known to worsen during hospital stay which is partly due to the poor recognition by the medical staff and adverse clinical routines. Studies have repeatedly shown that clinical malnutrition however has serious implications for recovery from disease, trauma and surgery and is generally associated with increased morbidity and mortality both in acute and chronic diseases. Length of hospital stay is significantly longer in malnourished patients and higher treatment costs are reported in malnutrition. Since it has been demonstrated that proper nutritional care can reduce the prevalence of hospital malnutrition and costs, nutritional assessment is mandatory in order to recognise malnutrition early and initiate timely nutritional therapy.

BACKGROUND & AIM: Nutritional status frequently deteriorates during chemotherapy in cancer. This is associated with a poor outcome. Since creatine supplementation has shown promising results in various diseases, we investigated the effects of creatine on nutritional status in patients with colorectal cancer undergoing chemotherapy. METHODS: Thirty patients with colorectal cancer undergoing chemotherapy were randomised to receive either creatine (n=16) or placebo (n=15) for 8 weeks. Body composition was determined with bioelectrical impedance analysis; muscle function by hand grip, hip flexion and knee extension strength and quality of life (QoL) was assessed by the QLQ30 questionnaire. RESULTS: Neither muscle function, body cell mass (BCM) nor QoL improved, but phase angle, a marker of BCM and cell integrity, increased significantly in the intervention patients (5.3+/-0.3 degrees to 5.4+/-0.2 degrees , P=0.030). Evaluating patients with different chemotherapy regimens, however, only intervention patients undergoing less aggressive chemotherapy were shown to benefit, increasing phase angle (5.11+/-0.22 degrees to 5.51+/-0.30 degrees , P=0.043) as well as BCM (27.22+/-2.85 to 29.60+/-3.54kg, P=0.043). CONCLUSION: Creatine failed to improve muscle mass or function and QoL in colorectal cancer patients but improved bioimpedance parameters that are predictive of poor outcome. Creatine might therefore be useful in patients with milder chemotherapy in order to maintain or increase BCM whereas patients undergoing aggressive chemotherapy however are not likely to benefit.
