Chronic hyperglycemia, hypercholesterolemia, and metabolic syndrome are associated with risk of tendon injury.

Tendon injury is a considerable problem affecting both physically active and sedentary people. The aim of this study was to examine the relationship between markers for metabolic disorders (hyperglycemia, hypercholesterolemia, and metabolic syndrome) and the risk of developing tendon injuries requiring referral to a hospital. The Copenhagen City Heart Study is a prospective study of diabetic and non-diabetic individuals from the Danish general population with different physical activity levels. The cohort was followed for 3 years via national registers with respect to tendon injuries. Data from 5856 individuals (median age 62 years) were included. The overall incidence of tendon injury in both upper and lower extremities that required an out-patient or in-house visit to a hospital was ~5.7/1000 person years. Individuals with elevated HbA1c (glycated hemoglobin) even in the prediabetic range (HbA1c>5.7%) had a ~3 times higher risk of tendon injury in the lower extremities only, as compared to individuals with normal HbA1C levels. Hypercholesterolemia (total cholesterol>5 mmol/L) increased risk of tendon injury in the upper extremities by ~1.5 times, and individuals with metabolic syndrome had ~2.5 times higher risk of tendon injury in both upper and lower extremities. In conclusion, these data demonstrate for the first time in a large cohort with different physical activity levels that the indicators for metabolic syndrome are a powerful systemic determinant of tendon injury, and two of its components, hyperglycemia and hypercholesterolemia, each independently make tendons susceptible for damage and injury.

Nutritional status according to the mini nutritional assessment (MNA)® as potential prognostic factor for health and treatment outcomes in patients with cancer - a systematic review.

BACKGROUND: Patients with cancer have an increased risk of malnutrition which is associated with poor outcome. The Mini Nutritional Assessment (MNA®) is often used in older patients with cancer but its relation to outcome is not known. METHODS: Four databases were systematically searched for studies relating MNA-results with any reported outcome. Two reviewers screened titles/abstracts and full-texts, extracted data and rated the risk of bias (RoB) independently. RESULTS: We included 56 studies which varied widely in patient and study characteristics. In multivariable analyses, (risk of) malnutrition assessed by MNA significantly predicts a higher chance for mortality/poor overall survival (22/27 studies), shorter progression-free survival/time to progression (3/5 studies), treatment maintenance (5/8 studies) and (health-related) quality of life (2/2 studies), but not treatment toxicity/complications (1/7 studies) or functional status/decline in (1/3 studies). For other outcomes - length of hospital stay (2 studies), falls, fatigue and unplanned (hospital) admissions (1 study each) - no adjusted results were reported. RoB was rated as moderate to high. CONCLUSIONS: MNA®-result predicts mortality/survival, cancer progression, treatment maintenance and (health-related) quality of life and did not predict adverse treatment outcomes and functional status/ decline in patients with cancer. For other outcomes results are less clear. The moderate to high RoB calls for studies with better control of potential confounders.

Association between perioperative hyperoxia and cerebrovascular complications after laparotomy-A post-hoc follow-up study.

BACKGROUND: Perioperative hyperoxia has been linked to increased long-term mortality. Vasoconstrictive and cellular side effects to hyperoxia have been suggested to increase the risk of coronary and cerebral ischemia. The aim of this post-hoc analysis of a large randomized trial was to compare the effects of 80% vs 30% perioperative oxygen on the long-term risk of stroke or transient cerebral ischemia (TCI) in patients undergoing abdominal surgery. METHODS: A total of 1386 patients were randomized to 80% or 30% perioperative oxygen during acute or elective open abdominal surgery. Median follow-up was 3.9 years. Primary outcome was a composite of the long-term occurrence of stroke or TCI. Secondary outcomes included long-term mortality without stroke or TCI, and incidences of neurological admission, psychiatric admission, and dementia. Outcomes were analyzed in Cox regression models. RESULTS: Stroke or TCI occurred in 20 (3.0%) patients given 80% oxygen vs 22 (3.2%) patients given 30% oxygen with an adjusted hazard ratio (HR) of 0.96 [95% CI 0.52-1.76]. Composite secondary outcome of death, stroke, or TCI had a HR of 1.21 [95% CI 1.00-1.47] for 80% compared to 30% oxygen. HRs for secondary outcomes were HR 1.14 [95% CI 0.79-1.64] for neurological admission, 1.34 [95% CI 0.95-1.88] for psychiatric admission and 0.54 [95% CI 0.16-1.80] for dementia. CONCLUSION: Stroke or TCI did not seem related to perioperative inspiratory oxygen fraction. Due to few events, this study cannot exclude that perioperative hyperoxia increases risk of mortality, stroke, or TCI after abdominal surgery.

[Refeeding syndrome : Pathophysiology, risk factors, prevention, and treatment]. / Refeeding-Syndrom : Pathophysiologie, Risikofaktoren, Prophylaxe und Therapie.

Refeeding syndrome is a life-threatening complication that may occur after initiation of nutritional therapy in malnourished patients, as well as after periods of fasting and hunger. Refeeding syndrome can be effectively prevented and treated if its risk factors and pathophysiology are known. The initial measurement of thiamine level and serum electrolytes, including phosphate and magnesium, their supplementation if necessary, and a slow increase in nutritional intake along with close monitoring of serum electrolytes play an important role. Since refeeding syndrome is not well known and the symptoms can be extremely heterogeneous, this complication is poorly recognized, especially against the background of severe disease and multimorbidity. This overview aims to summarize the current knowledge and increase awareness about refeeding syndrome.

[Nutrition in dementia]. / Ernährung bei Demenzerkrankungen.

BACKGROUND: In the course of dementia sooner or later nutritional problems appear, and the question arises which interventions are effective in ensuring adequate nutrition and thus may contribute to the maintenance of health, functionality and independence. OBJECTIVE: This overview presents the state of knowledge regarding nutrition in dementia. METHODS: This work is based on the present guidelines of the European Society for Clinical Nutrition and Metabolism (ESPEN) on nutrition in dementia, which systematically investigated relevant available evidence. RESULTS: Nutritional interventions should be an integral component of dementia treatment. They should be based on a routine screening for malnutrition, followed by assessment when appropriate, and periodic body weight control in order to recognize problems early. In all stages of dementia, adequate oral nutrition can be supported by attractive, high-quality food according to individual needs served in a pleasant ambience, by adequate nursing support and treatment of underlying causes of malnutrition. If nutritional requirements are not met by usual or enriched food, oral nutritional supplements are recommended in order to improve nutritional status. Beneficial effects of energy and/or nutrient supplementation on cognitive abilities are however not proven. Artificial nutrition is only rarely indicated, namely after careful weighing of individual benefits and risks considering the patients (presumed) will. In patients with advanced dementia and in the terminal phase of life artificial nutrition is not recommended.

Micronucleus frequency in Danish schoolchildren and their mothers from the DEMOCOPHES population.

Micronucleus (MN) frequency is a biomarker for early genetic effects which is often used in human biomonitoring studies. Increased frequency of micronuclei has been associated with high levels of traffic exposure. Further high MN frequency was found predictive for cancer development in several studies of adults. In the present study, the MN frequency in blood samples from the Danish participants of the European pilot project DEMOCOPHES was analysed and related to the area of residence, self-reported and calculated exposure to road traffic as well as to mercury in hair and blood concentrations of persistent organic pollutants and dioxin-like activity measured in the same participants. The MN frequency analysis was performed with the cytokinesis-block micronucleus (CBMN) assay and included 100 children and 119 mothers. We found a significant correlation between mothers and children in the levels of micronuclei in 1000 binucleated T lymphocytes (‰MNBN) and in the proliferation index. Further the levels of ‰MNBN were significantly higher in mothers compared with their children. No significant associations were found for ‰MNBN for traffic related exposure in neither children nor their mothers. In children, a 2.5 times higher micronuclei in mononuclear T lymphocytes were found in children living within 50 m of a busy road, however, this was not found in mothers or in MNBN and the effect of exposure to road traffic on MN frequency needs further investigation. No significant associations were found between MN frequencies and the other biomarkers measured in the same participants.

Evaluation of the nutritional status of older hospitalised geriatric patients: a comparative analysis of a Mini Nutritional Assessment (MNA) version and the Nutritional Risk Screening (NRS 2002).

BACKGROUND: The present study aimed to evaluate a short-form (MNA-SF) version of the Mini Nutritional Assessment (MNA), in which some of the items were operationalised, based on scores from tools used for a comprehensive geriatric assessment, as a method for analysing the nutritional status of hospitalised geriatric patients. We compared this MNA-SF version with the corresponding MNA long-form (MNA-LF) and Nutritional Risk Screening 2002 (NRS 2002) in terms of completion rate, prevalence and agreement regarding malnutrition and/or the risk of this. METHODS: In total, 201 patients aged ≥65 years who were hospitalised in geriatric wards were included in this analysis. RESULTS: The MNA-SF, MNA-LF and NRS 2002 were completed in 98.0%, 95.5% and 99.5% of patients (P = 0.06), respectively. The MNA-SF, MNA-LF and NRS 2002 categorised 93.4%, 91.1% and 66.0% of patients as being malnourished or at risk of being malnourished (P < 0.001). Agreement between the MNA-SF and MNA-LF was substantial (κ = 0.70, P < 0.001). No agreement between the MNA-SF and NRS 2002 was found (κ = -0.12, P < 0.001). Interestingly, NRS 2002 part 1 (prescreening) revealed a false negative rate of 21.0% (only in patients aged ≥70 years who showed moderate disease severity) in relation to the NRS 2002 part 2. CONCLUSIONS: The MNA-SF version emerged as a useful tool for evaluating the nutritional status of hospitalised geriatric patients. The NRS 2002 part 1 showed limited value as a prescreening aid in relation to the NRS 2002 part 2 in the same group of patients.

[Nutritional management in geriatric traumatology]. / Ernährungsmanagement in der Alterstraumatologie.

The prevalence of malnutrition or the risk of malnourishment is high among orthogeriatric patients and a poor nutritional status is associated with a negative outcome. A comprehensive management of preoperative and postoperative nutritional and fluid intake in these patients can help to improve the situation. The management includes identification of patients affected, a thorough assessment of the nutritional status, work-up of possible underlying causes, documentation of nutritional and fluid intake and, most importantly, procedures to improve the preoperative and postoperative nutritional situation. This article gives an overview of the recently updated recommendations on nutritional management in orthogeriatric patients as published by the orthogeriatric working group of the German Geriatric Society.

Association of the blood eosinophil count with hematological malignancies and mortality.

Blood eosinophilia (≥0.5 × 10(9) /l) may be an early sign of hematological malignancy. We investigated associations between levels of blood eosinophils and risks of hematological malignancies and mortality in order to provide clinically derived cut-offs for referral to specialist hematology care. From the Copenhagen Primary Care Differential Count (CopDiff) Database, we identified 356,196 individuals with at least one differential cell count encompassing the eosinophil count during 2000-2007 and matched these laboratory data with Danish nationwide health registers. We used multivariable logistic regression to calculate odds ratios (ORs) for the 4-year incidences of hematological malignancies and mortality between the eosinophil counts and a reference count of 0.16 × 10(9) /l which was the median eosinophil count in our data. Risks of hematological malignancies and mortality increased above the median eosinophil count. At the 99th percentile, corresponding to an eosinophil count of 0.75 × 10(9) /l, risks of hematological malignancies were increased more than twofold with OR (95% C.I.) of 2.39 (1.91-2.99). Interestingly, risks reached a plateau around an eosinophil count of 1.0 × 10(9) /l. Risks also increased when the eosinophil count approached zero. Here, counts associated relatively more with acute myeloid leukemia and myelodysplastic syndromes whereas counts above 0.16 × 10(9) /l associated more with myeloproliferative neoplasms. Eosinophil counts associate with hematological malignancies and mortality even below the definition of eosinophilia. The observed plateau of risks around 1.0 × 10(9) /l is important for physicians encountering patients with eosinophilia since even mild-to-moderate eosinophilia according to traditional definitions confers maximally increased risks of subsequent/subclinical hematological malignancy.

The Danish contribution to the European DEMOCOPHES project: A description of cadmium, cotinine and mercury levels in Danish mother-child pairs and the perspectives of supplementary sampling and measurements.

Human biomonitoring (HBM) is an important tool, increasingly used for measuring true levels of the body burdens of environmental chemicals in the general population. In Europe, a harmonized HBM program was needed to open the possibility to compare levels across borders. To explore the prospect of a harmonized European HBM project, DEMOCOPHES (DEMOnstration of a study to COordinate and Perform Human biomonitoring on a European Scale) was completed in 17 European countries. The basic measurements performed in all implemented countries of DEMOCOPHES included cadmium, cotinine and phthalate metabolites in urine and mercury in hair. In the Danish participants, significant correlations between mothers and children for mercury in hair and cotinine in urine were found. Mercury in hair was further significantly associated with intake of fish and area of residence. Cadmium was positively associated with BMI in mothers and an association between cadmium and cotinine was also found. As expected high cotinine levels were found in smoking mothers. For both mercury and cadmium significantly higher concentrations were found in the mothers compared to their children. In Denmark, the DEMOCOPHES project was co-financed by the Danish ministries of health, environment and food safety. The co-financing ministries agreed to finance a number of supplementary measurements of substances of current toxicological, public and regulatory interest. This also included blood sampling from the participants. The collected urine and blood samples were analyzed for a range of other persistent and non-persistent environmental chemicals as well as two biomarkers of effect. The variety of supplementary measurements gives the researchers further information on the exposure status of the participants and creates a basis for valuable knowledge on the pattern of exposure to various chemicals.

Nutrition for the older adult - Current concepts. Report from an ESPEN symposium.

BACKGROUND & AIMS: In view of the global demographic shift, a scientific symposium was organised by the European Society for Clinical Nutrition and Metabolism (ESPEN) to address nutrition-related challenges of the older population and provide an overview of the current state of knowledge. METHODS: Eighteen nutrition-related issues of the ageing global society were presented by international experts during the symposium and summarised in this report. RESULTS: Anorexia of ageing, dysphagia, malnutrition, frailty, sarcopenia, sarcopenic obesity, and the metabolic syndrome were highlighted as major nutrition-related geriatric syndromes. Great progress has been made in recent years through standardised definitions of some but not all syndromes. Regarding malnutrition, the GLIM approach has shown to be suitable also in older adults, justifying its continuous implementation. For anorexia of ageing, a consensus definition is still required. Intervention approaches should be integrated and person-centered with the aim of optimizing intrinsic capacity and maintaining functional capacity. Landmark studies like EFFORT and FINGER have impressively documented the potential of individualised and multifactorial interventions for functional and health benefits. Combining nutritional intervention with physical training seems particularly important whereas restrictive diets and drug treatment should generally be used with caution because of undesirable risks. Obesity management in older adults should take into account the risk of promoting sarcopenia. CONCLUSIONS: In the future, even more individualised approaches like precision nutrition may enable better nutritional care. Meanwhile all stakeholders should focus on a better implementation of currently available strategies and work closely together to improve nutritional care for older adults.

Diabetic foot disease: impact of ulcer location on ulcer healing.

BACKGROUND: Healing of heel ulcers in patients with diabetes is considered to be poor, but there is relatively little information on the influence of ulcer location on ulcer healing. METHODS: The influence of ulcer location on time to healing of diabetic foot ulcers was analysed by multivariate Cox regression analysis for 1000 patients included in the Eurodiale study, a prospective cohort study of patients with diabetic foot disease. RESULTS: Median time to healing was 147 days for toe ulcers [(95% confidence interval (CI) 135-159 days)], 188 days for midfoot ulcers (95% CI 158-218 days) and 237 days for heel ulcers (95% CI 205-269 days) (p < 0.01). The median time to healing for plantar ulcers was 172 days (95% CI 157-187 days) and 155 days (95% CI 138-172 days) for nonplantar ulcers (p = 0.71). In multivariate Cox regression analysis, the hazard ratio for ulcer healing for midfoot and heel ulcers compared with toe ulcers was 0.77 (95% CI 0.64-0.92) and 0.62 (95% CI 0.47-0.83), respectively; the hazard ratio for ulcer healing for plantar versus nonplantar ulcers was 1 (95% CI 0.84-1.19). Other factors significantly influencing time to healing were the duration of diabetes, ulcer duration, the presence of heart failure and the presence of peripheral arterial disease. CONCLUSIONS: Time to ulcer healing increased progressively from toe to midfoot to heel, but did not differ between plantar and nonplantar ulcers. Our data also indicate that risk factors for longer time to healing differ from factors that affect the ultimate number of ulcers that heal (healing rate).

[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.

[Reversal of aging and lifespan elongation. Current biomedical key publications and the implications for geriatrics]. / Alternsumkehr und Lebensspannenverlängerung : Aktuelle biomedizinische Schlüsselpublikationen und ihre Implikationen für die Geriatrie.

Biological aging means a time-dependent accumulation of changes to which a living organism is being exposed during its lifetime. Biological aging normally concurs with chronological aging the time frame of which is set by an upper limit, the lifespan (in humans approximately 120 years). New findings in experimental biogerontology are challenging both the dogma of irreversibility of biological aging and the preset species-specific limitations of life. The present overview first explains the general principle of rejuvenation and reversal of biological aging with paradigms from stem cell research. Secondly, recent key publications on artificial telomerase elongation and (alleged) lifespan enhancement by sirtuins and resveratrol will be discussed with an emphasis on the implications for (future) geriatric medicine.

[Translational research in geriatrics? A plea based on current biomedical key publications]. / Translationale Forschung in der Geriatrie? : Ein Plädoyer anhand aktueller biomedizinischer Schlüsselpublikationen.

Contemporary geriatric research focuses mainly on observational clinical studies and epidemiological surveys and the translation of basic scientific results from biogerontology into a clinical context is often neglected. Following a definition of translational research the article gives an overview of recent key publications in experimental biogerontology with a special emphasis on their relevance for clinical geriatrics. The topics dealt with include age-induced loss of skeletal muscle (sarcopenia), the aging immune system (immunosenescence) and neurodegenerative disorders (Alzheimer's and Parkinson's disease).

Vitamin D status and physical function in nursing home residents: a 1-year observational study.

OBJECTIVE: Low vitamin D blood levels are highly prevalent in elderly people, particularly in nursing home residents (NHR). A relation between vitamin D levels and physical function (PF) is described in several studies in older adults; however, data on NHR are scarce and there is presently no information on the time course of vitamin D levels and PF in this population. The aim of the present study was to describe the 25-hydroxyvitamin D [25(OH)D] status of NHR at baseline (t1) and after 1 year (t2) to examine whether 25(OH)D blood levels are related to PF at t1 and at t2, and whether changes in 25(OH)D levels over 1 year are related to changes in PF. METHODS: All NHR (≥ 65 years) without tube-feeding and severe acute or end-stage disease were asked to participate. At t1 and t2 fasting blood samples were taken for the analysis of 25(OH)D serum levels and PF was estimated by activities of daily living (Barthel ADL) and measured by handgrip strength (HGS) and timed 'up and go' test (TUG). RESULTS: In total, 115 residents, aged 87 (82-93) years (all data in median and 1st-3rd quartile), showed the following values for PF: ADL 50 (20-65) points, HGS 40 (30-50) kPa and TUG 26 (18-31) s. Vitamin D deficiency (< 50 nmol/l) was present in 93.9 % (70.4 % < 25 nmol/l) at t1 and in 71.2 % (57.3 % < 25 nmol/l) at t2. At t1 and at t2 a weak correlation between vitamin D level and PF (Spearman's correlation coefficient t1: ADL r = 0.367, HGS r = 0.313; t2: ADL: r = 0.247; all p < 0.01) was observed. There was no correlation between changes in vitamin D levels over 1 year and changes in PF. CONCLUSIONS: Almost all NHR included in the study showed vitamin D deficiency. 25(OH)D levels were weakly correlated to PF at baseline and at follow-up, and an increase in vitamin D levels was not associated with positive effects on PF in this study.

Towards developing a Core Outcome Set for malnutrition intervention studies in older adults: a scoping review to identify frequently used research outcomes.

PURPOSE: To conduct a scoping review to provide a systematic overview of outcomes used in nutritional intervention studies focused on the treatment of protein-energy malnutrition in older adults. METHODS: A systematic search of four electronic databases (Medline, EMBASE, CINAHL and Cochrane Central Register of Controlled Trials (CENTRAL) was performed to retrieve randomized controlled trials (RCTs), published until March 9, 2020, that evaluated the effect of nutritional interventions to treat protein-energy malnutrition in older adults and those at risk for malnutrition. Two authors screened titles, abstracts and full texts independently. One author extracted data that were cross-checked by another author. RESULTS: Sixty-three articles reporting 60 RCTs were identified. Most frequently used outcomes included body weight/body mass index (75.0% of RCTs), dietary intake (61.7%), functional limitations (48.3%), handgrip strength (46.7%), and body circumference (40.0%). The frequencies differed by setting (community, hospital and long-term care). For some outcomes there was a preferred assessment method (e.g., Barthel index for functional limitations), while for other outcomes (e.g., functional performance) a much greater variation was observed. CONCLUSION: A large variation in outcomes, not only across but also within settings, was identified in nutritional intervention studies in malnourished older adults and those at risk. Furthermore, for many outcomes there was a large variation in the used assessment method. These results highlight the need for developing a Core Outcome Set for malnutrition intervention studies in older adults to facilitate future meta-analyses that may enhance our understanding on the effectiveness of treatment.

Effects of an individualised nutritional intervention to tackle malnutrition in nursing homes: a pre-post study.

PURPOSE: Individualised interventions are recommended to tackle malnutrition in older adults, but approaches for nursing home (NH) residents are scarce. This study investigated the effects of an individualised nutritional intervention in NH residents with (risk of) malnutrition. METHODS: In a pre-post study, 6 weeks (w) of usual care were followed by 6w of intervention. The intervention consisted of up to three supplement modules (sweet and savoury protein creams and protein-energy drink, single or combined) and, if required, reshaped texture-modified meals (RTMM). RESULTS: Fifty residents completed the study (84 ± 8 years, 74% female). One-third (32%) received RTMM. Additional 258 ± 167 kcal/day and 23 ± 15 g protein/day were offered. Mean daily energy intake increased by 207 (95%CI 47-368, p = 0.005) kcal and protein intake by 14 (7-21, p < 0.001) g (w12 vs w1). Quality of life (QoL) increased in the subscale "care relationship" (+ 9 (3-15) points, p = 0.002, w12 vs w6). Body weight, handgrip strength, and other QoL subscales did not change. CONCLUSION: Our intervention improved dietary intake and one QoL subscale in NH residents with (risk of) malnutrition. As a next step, randomized controlled trials are needed to investigate the impact of individualised interventions more comprehensively.

Similar cardiovascular risk factor profile in screen-detected and known type 2 diabetic subjects.

OBJECTIVE. To compare the cardiovascular disease (CVD) risk factor profile in subjects with screen-detected type 2 diabetes (SDM) and subjects with known type 2 diabetes (KDM). DESIGN. Population-based, cross-sectional survey. SETTING AND SUBJECTS. In a single, semi-rural general practice 2082 subjects were between 20 and 69 years. Of those, 1970 subjects were invited, and a total of 1374 (69.7%) subjects were examined by blood tests, anthropometric measures, and self-administered questionnaires. RESULTS. Before the survey 19 persons were known to have type 2 diabetes. The screening revealed another 31 individuals with type 2 diabetes, diagnosed according to the 1999 World Health Organization criteria. Age, levels of blood pressure, BMI, and dyslipidaemia, and markers of haemostasis and inflammation were comparable in the two groups. Median age in the KDM group was 58 vs. 57 years in the SDM group, p = 0.82, 79% were male vs. 61%, p = 0.23. In both groups 74% had blood pressure ≥ 130/85 mmHg, p = 1.00. In both groups 90% had BMI ≥ 25, p = 1.00, and about half in both groups had BMI ≥ 30, p = 0.56. In the KDM group 63% had dyslipidaemia (low HDL cholesterol or elevated triglycerides) vs. 80% in the SDM group, p = 0.32. Median levels of plasminogen-activator-inhibitor (PAI-1), tissue plasminogen activator (t-PA), as well as fibrinogen and C-reactive protein (CRP) were without statistically significant differences in the two groups, p > 0.1. In contrast, in markers of glycaemic regulation statistically significant differences were found between groups. Median HbA1 was 8.0 vs. 6.5, p < 0.001. Median fasting whole blood glucose level was 8.8 mmol/L vs. 6.3 mmol/L, p < 0.001, and glucose at two hours during OGTT was 16.9 mmol/L vs. 11.2 mmol/L, p < 0.001. Median fasting serum insulin level was 52 pmol/L vs. 80 pmol/L, p = 0.039 and at two hours 127 pmol/L vs. 479 pmol/L, p < 0.001. CONCLUSIONS. The CVD risk-factor profile of SDM patients was similar to the expected adverse profile of patients with KDM. This indicates an already increased risk of cardiovascular disease in diabetic patients before the diabetes becomes clinically manifest, supporting the need for early diagnosis.

[Nutritional guidelines and standards in geriatrics]. / Leitlinien und Standards zur Ernährung in der Geriatrie.

Nutritional problems and deficiencies are widespread in geriatric institutions. On the other hand, benefits of different interventions to improve the nutritional situation of elderly people--from amelioration of mealtime ambience to the use of artificial nutrition--have been shown in many studies. In recent years, several guidelines and standards have been developed to facilitate the transfer of this scientific knowledge into practice. These are in particular the medical Guidelines for Enteral and Parenteral Nutrition in Geriatrics (DGEM/DGG and ESPEN), the DNQP Expert Standard for qualified nurses, the DGE Quality Standards for dietetic personnel, and the interdisciplinary BUKO-QS Standard. These guidelines and standards provide recommendations for adequate nutritional care and assistance for the institutionalized elderly person based on the scientific state of the art. They should be used as the basis for the development of local instructions for the management of nutritional problems and malnutrition. Elderly people will only profit, if these guidelines are used in daily routine.
