Malnutrition in the elderly and its relationship with other geriatric syndromes.

BACKGROUND & AIMS Age related decline in food intake is associated with various physiological, psychological and social factors. Our aim was to assess the nutritional status of our elderly patients and its association with other geriatric syndromes. METHODS In this cross-sectional population based study, Mini Nutritional Assessment (MNA) test was used to evaluate nutritional status of 413 elderly patients who were admitted to our outpatient clinic in the last 12 months. MNA test results were compared with the laboratory findings and established geriatric syndromes. RESULTS Poor nutritional status was found in 44% of the patients (n=181: 13% malnutrition, 31% malnutrition risk). Malnutrition rate was higher among those with subsequent hospitalization (n=122, 25% vs 8%). Patients with poor nutritional status had lower blood haemoglobin, serum total protein and albumin, and revealed more chronic diseases and geriatric syndromes (6 ± 2 vs 3 ± 2, p<0.0001). Patients with depression, fecal incontinence, decreased cognitive function and functional dependence showed poor nutritional status according to MNA test results. CONCLUSIONS Malnutrition rate of our patients was comparable with the previous data. Malnutrition risk showed positive correlation with the number of existing geriatric syndromes. Depression, dementia, functional dependence and multiple co-morbidities were associated with poor nutritional status.

Prevalence of sarcopenia and its association with functional and nutritional status among male residents in a nursing home in Turkey

The prevalence of sarcopenia differs between different populations, ages, gender and between settings such as the community and nursing homes. Studies on the association of sarcopenia with functional status revealed conflicting results whereas its association with nutritional status is well documented. We aimed at investigating the prevalence of sarcopenia and its association with functional and nutritional status among male residents in a nursing home in Turkey. Fat free mass (FFM) was detected by bioelectric impedance analysis. Functional status was evaluated with Katz activities of daily living (ADL) and Lawton Instrumental activities of daily living (IADL). Nutritional assessment was performed by Mini Nutritional Assessment Test (MNA®). One hundred fifty-seven male residents composed the study cohort. Mean age was 73.1 ± 6.7 years. The prevalence of sarcopenia was 85.4%. No significant correlation was found between sarcopenia and ADL or IADL. There was a weak but significant correlation between IADL score and FFM (r = 0.18; p = 0.02). Sarcopenic residents had lower MNA score than non-sarcopenic residents (18.1 ± 3.2 vs. 21.8 ± 0.8, p = 0.02). FFM was significantly lower in the residents with malnutrition compared to well-nourished residents (26.8 ± 1 kg/body surface area vs. 28.1 ± 1.8 kg/body surface area, p < 0.05). In conclusion, the prevalence of sarcopenia was very high among male nursing home residents in Turkey. Sarcopenia was associated with low nutritional status but not with functional status.

Which body mass index (BMI) is better in the elderly for functional status

BMI is commonly used indicator of malnutrition and 18.5-24.9 kg/m(2) is generally regarded optimal. However, there is an ongoing debate on ideal range for elderly. BMI cut-off values vary also between ethnic groups. We aimed to investigate relationships between BMI, functional status and malnutrition in elderly living in a nursing home in Turkey. BMIs of 254 residents were calculated. Chronic diseases and currently used drugs were noted. Functional status was evaluated with Katz-activities-of-daily-living (ADL) and Lawton-instrumental-activities-of-daily-living (IADL). Nutritional assessment was performed by Mini-Nutritional-Assessment (MNA) test. Mean age was 75.2 ± 8.2 years. Subjects were classified into 4 groups as BMI <18.5, 18.5-24.9, 25-29.9, and ≥ 30.0 kg/m(2). ADL scores and IADL scores were higher in higher BMI groups. There were no differences in terms of age-number of chronic diseases. Even in BMI ≥ 35 kg/m(2) residents, ADL was significantly higher than 25-34.9 kg/m(2) residents. BMI was significantly correlated with ADL and IADL scores. In Groups 3 and 4, there were 22.2% and 9.1% residents without normal nutrition, respectively. Better functional status was associated with higher BMI values even in BMIs ≥ 30 kg/m(2). In elderly, relative high rates of undernutrition may be present in BMIs regarded as overweight or obese.

Bsmi polymorphism in the vitamin D receptor gene is associated with leg extensor muscle strength in elderly men.

Background and aims: Sarcopenia is defined as a reduction in skeletal muscle mass, strength, and endurance observed with advancing age. Although Vitamin D receptor (VDR) polymorphism is reported to be associated with muscle mass and strength, evidence for this is limited and conflicting. In this study, we examined the association between the polymorphisms of VDR gene BsmI, TaqI and FokI and muscular mass and strength in elderly men. Methods: This is a cross-sectional study conducted in a university hospital. One hundred and twenty men over 65 years of age participated, all participants were active men living independently in Istanbul, who were followed as outpatients in geriatric polyclinics. Most common diagnoses were hypertension, hyperlipidemia, and mild to moderate osteoarthritis. Morbid obese patients were not included in the study. Genomic DNA was extracted from peripheral blood, and VDR genotypes were determined by the polymerase chain reaction. The peak torque of the knee flexors and extensors was measured on a Cybex 350 dynamometer. Body muscle mass was calculated by using bioelectric impedance analysis. Results: The extensor strength of the knee was higher in BB homozygotic men than in the Bb/bb group. No significant association was found with TaqI and FokI haplotypes. There was no significant association between muscle mass and strength, or between muscle mass and VDR genotype. Conclusion: Our data suggest that VDR gene BsmI polymorphism is associated with muscular strength in elderly men.

Acute renal failure due to leukaemic infiltration in chronic lymphocytic leukaemia: case report

A 73‐year‐old woman was presented with altered mental status and disorientation. She was diabetic and hypertensive, and she had experienced an ischemic cerebrovascular accident 3 years ago. Physical examination revealed the findings of chronic obstructive pulmonary disease, cor pulmonale and congestive heart failure. Hepatomegaly, splenomegaly and ascites were found and might be associated with postsinusoidal portal hypertension secondary to congestive heart failure. Laboratory tests showed uremia, lymphocytosis and thrombocytopenia. Neurologic findings were related with uremia and hypoxia. Multiple pathologic lymphadenopathies were seen in abdominal ultrasonography and thoracic computed tomography. Bone marrow histology indicated chronic lymphocytic leukaemia (CLL). The reason for acute renal failure was leukaemic infiltration of the kidneys due to CLL that was shown with renal biopsy. Blood urea nitrogen (BUN) and serum creatinine responded well to cyclophosphamide and methyl prednisolone treatment. In CLL, direct renal involvement is frequently seen in autopsy studies especially in advanced disease, however, renal failure due to leukaemic infiltration is extremely rare.

Fever of unknown origin: a report of 57 cases

Fever of unknown origin (FUO) is defined as the body temperature higher than 38.3 °C on several occasions and lasting longer than 3 weeks, with the aetiology remaining uncertain after 1 week of investigation. In this study, we reviewed 57 patients with FUO hospitalised in our inpatient department between 1998 and 2003. The median age of the patients was 44 years (17–84), and 26 were males (46%), while 31 were females (54%). In 24 patients (42%), infectious diseases such as tuberculosis (12 patients) and brucellosis (5 patients) were found under the aetiology of FUO. Inflammatory rheumatic diseases were the second most common cause of FUO (17 patients, 30%), while malignancies were found in 10 patients (18%). In six patients (10%), aetiology could not be identified. In conclusion, infectious diseases especially tuberculosis and brucellosis are the leading causes of FUO in our country.

Nutritional risk in hospitalized patients: impact of nutritional status on serum prealbumin

OBJETIVO: Falha no reconhecimento e acompanhamento do estado nutricional e a razao mais importante da desnutricao em pacientes hospitalizados. Este estudo objetivou avaliar o estado nutricional dos pacientes e comparar os resultados com os niveis sericos de pre-albumina. METODOS: Foram incluidos 97 pacientes no estudo, internados consecutivamente. O risco de desnutricao foi avaliado de acordo com dados antropometricos e com a Avaliacao Subjetiva Global e Triagem de Risco Nutricional 2002. Os estados nutricionais dos pacientes foram comparados com suas idades, sexo, indice de massa corporal, historico medico, perda de peso e analises bioquimicas, incluindo pre-albumina e tempo de permanencia hospitalar. RESULTADOS: De acordo com o Triagem de Risco Nutricional 2002, 57% dos pacientes estavam desnutridos ou em risco de desnutricao, apresentando boa correlacao com o Avaliacao Subjetiva Global (p<0,001, r=0,700). A analise multivariada mostrou correlacoes positivas entre desnutricao e idade, perda de peso, malignidade e proteina reativa-C (p=0,046, p=0,001, p=0,04 e p=0,002). Um escore ³3 no Triagem de Risco Nutricional 2002 foi associado a internacao prolongada (p<0,001). Houve correlacao entre pre-albumina serica e o estado nutricional, independente do numero de doencas cronicas e biomarcadores de inflamacao (p=0,01). A sensibilidade, especificidade, valor preditivo positivo, valor preditivo negativo e valor diagnostico da pre-albumina na avaliacao do risco de desnutricao foram de 94%, 32%, 0,67, 0,78 e 69, respectivamente. Apos sete dias de suporte nutricional, o risco de desnutricao caiu em 12% (p<0,001) e os niveis sericos de pre-albumina aumentaram em 20% (p=0,003). CONCLUSAO: Ao inves de refletir o estado nutricional global do paciente, niveis sericos baixos de sericos de pre-albumina podem ser vistos como um sinal de maior risco de desnutricao, exigindo uma avaliacao nutricional mais extensa. A analise serica de pre-albumina pode ser usada para o monitoramento de pacientes recebendo suporte nutricional.

Low skeletal muscle mass index is associated with function and nutritional status in residents in a Turkish nursing home.

Abstract Introduction: To determine the prevalence of low muscle mass (LMM) and the relationship between LMM with functional and nutritional status as defined using the LMM evaluation method of European Working Group on Sarcopenia in Older People (EWGSOP) criteria among male residents in a nursing home. Methods: Male residents aged >60 years of a nursing home located in Turkey were included in our study. Their body mass index (BMI) kg/m2, skeletal muscle mass (SMM-kg) and skeletal muscle mass index (SMMI-kg/m2) were calculated. The participants were regarded as having low SMMI if they had SMMI <9.2 kg/m2 according to our population specific cut-off point. Functional status was evaluated with Katz activities of daily living (ADL) and Lawton Instrumental Activities of Daily Living (IADL). Nutritional assessment was performed using the Mini Nutritional Assessment (MNA). The number of drugs taken and chronic diseases were recorded. Results: One hundred fifty-seven male residents were enrolled into the study. Their mean age was 73.1 ± 6.7 years with mean ADL score of 8.9 ± 2.0 and IADL score of 8.7 ± 4.6. One hundred twelve (71%) residents were aged >70 years. Thirty-five men (23%) had low SMMI in group aged >60 years, and twenty-eight subjects (25%) in the group aged >70 years. MNA scores were significantly lower in residents with low SMMI compared with having normal SMMI (17.1 ± 3.4 versus 19.6 ± 2.5, p = 0.005). BMI was significantly lower in the residents with low SMMI compared with normal SMMI (19.6 ± 2.7 versus 27.1 ± 4.1, p< 0.001). ADL scores were significantly different between residents with low SMMI and normal SMMI in those aged >70 years (8.1 ± 2.6 versus 9.1 ± 1.6, p = 0.014). In regression analyses, the only factor associated with better functional status was the lower age (p = 0.04) while the only factor associated with better nutrition was higher SMMI (p = 0.01). Conclusions: Low SMMI detected by LMM evaluation method of EWGSOP criteria is prevalent among male nursing home residents. There is association of low SMMI with nutritional status and probably with functional status within the nursing home setting using the EWGSOP criteria with Turkish normative reference cut-off value.

Uncomplicated diabetes does not accelerate age-related sarcopenia

Abstract Background: Diabetes is reported to accelerate sarcopenia (age-related loss of muscle mass and function). We aimed to assess muscle mass and strength in elderly diabetics, elderly non-diabetics, younger diabetics and healthy subjects, and to define correlates of muscle mass and strength in these subjects. Methods: Sixteen elderly diabetics, 16 younger diabetics, 16 elderly non-diabetics and 18 younger non-diabetics were included. Elderly and diabetic subjects were first evaluated with exercise testing. Isokinetic leg extension and flexion tests were performed using a Cybex 350 dynamometer. Muscle mass was calculated using bioelectric impedance analysis. Results: Muscle mass was similar between all groups; however, muscle strength was significantly lower in diabetic and non-diabetic elderly subjects compared with younger diabetic subjects and non-diabetics. Muscle strength was positively correlated with albumin, metabolic equivalent and hemoglobin, and inversely correlated with age, HbA1c, functional capacity and CRP. Independent correlates of muscle strength were age and hemoglobin. There was no clinically significant correlate of muscle mass. Presence or duration of diabetes was not associated with muscle mass or strength. Conclusions: Uncomplicated diabetes does not seem to accelerate aging-related muscle mass or strength loss. Exercise test parameters may be useful markers in the screening of sarcopenia.
