Gastrointestinal tolerance and plasma status of carotenoids, EPA and DHA with a fiber-enriched tube feed in hospitalized patients initiated on tube nutrition: Randomized controlled trial.

BACKGROUND & AIMS: During the first days of tube feeding (TF) gastrointestinal (GI) complications are common and administration of sufficient nutrition is a challenge. Not all standard nutritionally complete formulas contain dietary fiber, fish oil or carotenoids, key dietary nutrients for health and wellbeing. The aim of this study was to investigate the effects of a fiber, fish oil and carotenoid enriched TF formula on diarrhea, constipation and nutrient bioavailability. METHODS: A multi-center randomized, double-blind, controlled, parallel trial compared the effects of a dietary fiber, fish oil and carotenoid-enriched TF formula (test) with an isocaloric non-enriched formula (control) in 51 patients requiring initiation of TF. Incidence of diarrhea and constipation (based on stool frequency and consistency) was recorded daily. Plasma status of EPA, DHA and carotenoids was measured after 7 days. RESULTS: The incidence of diarrhea was lower in patients receiving the test formula compared with the control group (19% vs. 48%, p = 0.034). EPA and DHA status (% of total plasma phospholipids) was higher after 7 days in test compared with control group (EPA: p = 0.002, DHA: p = 0.082). Plasma carotenoid levels were higher after 7 days in the test group compared with control group (lutein: p = 0.024, α-carotene: p = 0.005, lycopene: p = 0.020, ß-carotene: p = 0.054). CONCLUSIONS: This study suggests that the nutrient-enriched TF formula tested might have a positive effect on GI tolerance with less diarrhea incidence and significantly improved EPA, DHA and carotenoid plasma levels during the initiation of TF in hospitalized patients who are at risk of diarrhea and low nutrient status.

Do doctors know how much nutrition patients need--a survey from Germany?

For the diagnosis, prevention and therapy of malnutrition, it is important to estimate the energy and fluid requirements of an individual patient. To our knowledge, it is unknown how accurately medical doctors can estimate the energy and fluid requirements of patients in a clinical routine situation. Hence, we conducted the following survey. A written face-to-face survey about the energy and fluid requirements of and tube feeding and fluid recommendations for a typical patient was performed with 179 medical doctors. An estimation error of >15% was defined as relevant. The results revealed substantial variations in estimating the energy and fluid needs of the patient. A total of 25% of the participants underestimated the energy requirements, and 47% of the participants underestimated the fluid requirements. In addition, 68% of the participants recommended a daily dose of tube feeding that was <85% of the reference value. A substantial proportion of medical doctors show a lack of knowledge concerning energy and fluid requirements, which demonstrates a need for better medical education with regard to nutrition.

[Management of malnutrition in geriatric hospital units in Germany]. / Die Ernährungsversorgung in geriatrischen Krankenhausabteilungen in Deutschland.

INTRODUCTION: Elderly hospitalized patients have a high risk for developing malnutrition. The causes for an impaired nutritional status in old age are various and the impact is far-reaching. Malnutrition is a comorbidity that is well treatable and various studies show the favorable effect of nutrition therapy on nutritional status and prognosis. In the past few years, several guidelines have been developed to improve nutritional management and to ensure standardized procedures to identify patients at nutritional risk who will benefit from nutrition therapy. However, it is still not clear to what extent nutrition management has been implemented in geriatric wards in Germany. AIM: This survey is intended to give an overview on the situation of the current diagnosis and therapy of malnutrition and nutritional management in geriatric hospital units for acute and rehabilitative care. METHODS: In 2011, the task force of the German Geriatric Society ("Deutsche Gesellschaft für Geriatrie", DGG) developed a questionnaire which was sent out to 272 directors of geriatric hospital and rehabilitational units. Included were questions regarding the size and staffing of the hospital and wards, food provision, diagnosis and therapy of malnutrition, as well as communication of malnutrition and nutrition therapy in the doctor's letter. RESULTS: A total of 38% of the questioned units answered. The following information was compiled: 31% of the geriatric facilities employed a doctor with training in clinical nutrition, 42% employ dieticians or nutritional scientists, and 90% speech and language pathologists. In 36% of the wards, a so-called geriatric menu is offered (small portions, rich in energy and/or protein, easy to chew). In 89% of the wards, snacks are available between meals. Diagnosis of malnutrition is mainly done by evaluation of weight and BMI. Validated and established screening tools are only used in 40% of the geriatric wards. Food records are carried out in 64% of the units when needed. Diagnosed malnutrition and nutrition therapy are underreported in the doctor's letter. Dental care beyond emergency care is rarely provided in 67% of wards and never in 23% of units. CONCLUSION: The use of validated screening instruments is clearly underrepresented and therapy algorithms are rarely implemented in German geriatric hospital units. There are a variety of nutrition interventions available, but it is unclear how patients at nutritional risk are identified. The data on the efficacy of nutrition therapy in elderly patients are very convincing and the integration of nutrition screening in the basic geriatric assessment seems sensible. The establishment of standardized procedures for nutrition intervention and therapy recommendations in the doctor's letter would be useful to ensure sustainability of nutrition therapy.

Increased intestinal permeability in malnourished patients with liver cirrhosis.

BACKGROUND/OBJECTIVE: Malnutrition is a prominent feature in liver cirrhosis, with deleterious impact on clinical outcome. The objective of this study is to investigate whether malnutrition is associated with increased gastrointestinal permeability in liver cirrhosis reflected by altered urinary excretion of non-metabolizable sugar probes. SUBJECTS/METHODS: Patients with advanced liver cirrhosis (Child Pugh Score B or C) were recruited. Nutritional status was determined according to the Subjective Global Assessment. Intestinal permeability was assessed by measuring the urinary excretion of orally administered, non-metabolized sugar probe molecules. The lactulose/mannitol ratio served as marker for intestinal permeability and reflects non-carrier-mediated transcellular and paracellular transport of the small intestine during the first 5 h. Sucrose recovery in urine within the first 5 h reflects gastroduodenal permeability; sucralose recovery in urine 5-26 h after consumption reflects colonic permeability. RESULTS: Sixty-four patients (56.7±10.8 years; 33% female) were included in the study. Twenty-one patients were considered well nourished according to the Subjective Global Assessment, 23 moderately nourished and 20 patients severely malnourished; 74% had alcoholic liver disease and 67% had cirrhosis stage Child C. Gastroduodenal and colonic permeability was significantly increased in patients with liver cirrhosis compared with 63 healthy controls (0.23±0.22 and 1.37±1.42% vs 0.14±0.10 and 0.41±0.72% in controls), but not different between well and malnourished subjects. Small intestinal permeability (lactulose/mannitol ratio) was increased in all patients (0.069±0.055%) and further increased in malnourished patients (0.048±0.031% vs 0.084±0.061%, P=0.004) due to decreased mannitol recovery only. CONCLUSIONS: Gastric, small intestinal and even colonic permeability was altogether increased in liver cirrhosis, and malnutrition was associated with further increased small intestinal permeability indicative of villous atrophy.

The impact of self-perceived masticatory function on nutrition and gastrointestinal complaints in the elderly.

OBJECTIVES: Impaired masticatory function is generally considered to be a contributing factor in the development of malnutrition (1, 2). Furthermore, the exclusion of essential and high-fibre foods from the subjects' diets, due to chewing problems, may induce gastrointestinal disorders (3-5). OBJECTIVE: The impact of masticatory function on malnutrition and gastrointestinal symptoms was evaluated. DESIGN, SETTING, AND PARTICIPANTS: This prospective cross-sectional study was conducted in four nursing homes in Berlin, Germany. 119 residents (mean 86, ± 8.0 years, 62-102) took part in the study. MEASUREMENTS: Dental status, denture quality, prosthetic condition as well as masticatory ability and gastrointestinal symptoms were evaluated by clinical examination or interview. Nutritional state was determined according to Mini Nutritional Assessment (MNA). RESULTS: The mean Body Mass Index was 24.4, ±4.9 kg/m² (17% < 20 kg/m²). The mean MNA was 22.5, ±4.3, 51.3% below normal. 54.5% of the dentures were poorly fitting. No significant relationships were found between the MNA and dental parameters except loose fit of dentures. However, there was significantly more food avoidance among the subjects with stated chewing problems, discomfort with dentures or ill-fitting dentures and there were significantly more digestive complaints among this group. CONCLUSIONS: Impairments of masticatory function may lead to food avoidance and to a higher incidence of digestive complaints.

Cognitive function is associated with body composition and nutritional risk of geriatric patients.

BACKGROUND: Most patients with dementia lose body weight over the course of the disease. Yet it is not known whether this weight loss is predominantly in the form of fat-free mass (FFM) or fat mass (FM), the latter of which one would expect if the weight loss were caused simply by a chronic decrease of energy intake. OBJECTIVES: To determine body composition and nutritional risk in geriatric patients and their association with cognitive function. DESIGN: A retrospective, cross-sectional single-center database analysis. METHODS: We analyzed 4,095 consecutive geriatric hospital patients for body composition, nutritional risk, need of care and cognitive function using bioelectric impedance analysis, NRS 2002, Barthel Index and Mini Mental State Examination. RESULTS: Subjects with cognitive dysfunction showed significant lower body weight, body mass index (BMI), FM, fat mass index, FFM and fat-free mass index and a higher NRS score compared to cognitively intact subjects. Mean body weight decreased 10.2%, mean FM decreased 21.1%, mean FFM decreased 5.9% and mean NRS 2002 score increased from 2.1 to 3.0 points with increasing cognitive deterioration. A multivariate analysis revealed that cognitive dysfunction, age and female gender were all significant risk factors for a low body mass index and a low fat mass index. Age, male gender and need of care, but not cognitive dysfunction, were risk factors for a low fat-free mass index. CONCLUSION: Dementia patients seem to lose predominantly fat mass with weight loss. Female dementia patients are at a higher nutritional risk than male patients, presumably as a result of their different social situation in old age. That is why the nutritional state of female patients with dementia requires special attention.

Cost-effectiveness of a 3-month intervention with oral nutritional supplements in disease-related malnutrition: a randomised controlled pilot study.

BACKGROUND/OBJECTIVES: Nutritional intervention with oral nutritional supplements (ONS) has been shown to increase quality of life in malnourished patients. We investigated whether post-hospital supplementation with ONS is cost-effective according to international benchmarks in malnourished patients. SUBJECTS/METHODS: In total, 114 malnourished patients (50.6±16.1 years, 57 female) with benign gastrointestinal disease were included and randomised to receive either ONS for 3 months and dietary counselling at discharge (intervention, n=60) or only dietary counselling at discharge (control group, n=54). Nutritional status was assessed with Subjective Global Assessment. Intervention patients documented daily intake of ONS; quality of life was assessed with Short-Form (SF)-36 Health Survey and SF-36 values were transformed into health-status utilities. Quality-adjusted life years (QALYs) were calculated by adopting the area under the curve method. We used two different pricing scenarios for ONS (minimum price: [euro]2.30 and maximum: [euro]2.93/tetrapack). The incremental cost-effectiveness ratio (ICER) of supplementation with ONS was calculated for both price scenarios. All analyses were corrected for age and gender. RESULTS: Intervention patients consumed 2.4±0.8 ONS per day. Intervention and control patients did not differ in their health status utilities at baseline (0.594±0.017 vs 0.619±0.018), but after 3 months, the health status utilities were significantly higher in intervention patients than in control patients (0.731±0.015 vs 0.671±0.016, P=0.028). Intervention was associated with significantly higher costs (ICER: [euro]9497 and [euro]12,099/additional QALY, respectively) but deemed cost-effective according to international thresholds (< [euro]50,000/QALY). CONCLUSIONS: A 3-month intervention with ONS increases quality of life in malnourished patients. This treatment appears to be cost-effective according to international benchmarks.
