RESUMEN
OBJECTIVE: The aim of the study is to assess the risk of malnutrition among institutionalized elderly individuals in North Bohemia and compare it to the risk of malnutrition in the capital city of Prague, Czech Republic. In the Czech Republic, very few studies have been conducted with the goal of describing and evaluating the nutritional status of the institutionalized elderly. METHODS: In this study, data was collected from 254 elderly individuals (aged ≥ 65) residing in retirement homes in North Bohemia and then compared with similar data for the elderly living in retirement homes in Prague (the data from Prague were previously published in 2013). The data included an Mini-Nutritional Assessment (MNA) test; anthropometric measurements - Body Mass Index (BMI), waist circumference, triceps skinfold thickness; and biochemical parameters - albumin, prealbumin, transferrin, urea, and creatinine. RESULTS: Mean BMI values were 27.4 kg/m2 for females and 26.3 kg/m2 for males. According to the MNA questionnaire, 10.4% of all tested elderly were malnourished and 50.8% were at risk of malnutrition; lager proportion of females were found to be malnourished than males. Biochemical indicators supported the MNA results. MNA categories correlated positively with independence (r = 0.56; p < 0.001), mental status (r = 0.54; p < 0.001), mobility (r = 0.46; p < 0.001), calf circumference (r = 0.42; p < 0.001), BMI, and the ability to self-feed (both r = 0.37; p < 0.001). The percentage of institutionalized elderly with malnutrition living in North Bohemia and Prague were about the same; however, the percentage of those at risk of malnutrition was higher in North Bohemia (p = 0.006). CONCLUSION: Study results confirmed that the institutionalized elderly face issues that lower their nutritional status and put them at increased risk; clearly these issues need urgent attention.

BACKGROUND: There is limited research examining the chemical load of toxic metals in the elderly. The aim of the present study was two-fold: to determine the body burden of lead, cadmium and mercury in association with age, gender, locality, lifestyle factors and potential health impacts among this population and to compare the values with blood values from the general Czech population aged 18-64 years. METHODS: Lead, cadmium and mercury were examined in the blood of institutionalized senior citizens (46 males, 151 females aged 61-100 years) from two localities in the Czech Republic (Prague and Teplice) from 2009 through 2011. Measurements were made using inductively coupled plasma mass spectrometry (Pb, Cd) and a single purpose spectrometer AMA 254 (Hg). RESULTS: Geometric means (GM) of whole blood lead (B-Pb), cadmium (B-Cd) and mercury (B-Hg) levels were 25.3µg/l, 0.55µg/l and 0.21µg/l, respectively. No age-related differences were found for B-Pb and B-Cd levels but a negative correlation with age was observed for B-Hg levels (p=0.04). B-Pb levels in men were significantly higher than in women (GM 29.9µg/l vs. 24.1µg/l). B-Cd was significantly higher in women (GM 0.57µg/l) than in men (0.50µg/l) (p=0.007) and in smokers (GM 1.29µg/l) than in nonsmokers (GM 0.53µg/l) (p=<0.001) and in seniors from Prague (GM 0.60µg/l) compared to those from Teplice (GM 0.43µg/l) (p=<0.001). Seniors with a history of chronic kidney disease, stroke and those using psycho-pharmaceuticals had higher B-Pb levels (p=0.008, 0.04 and 0.05, resp.), seniors diagnosed with atherosclerosis had higher B-Cd levels (p=0.002) and seniors using psycho-pharmaceuticals had higher B-Hg levels (p=0.07). B-Hg levels were also positively correlated with blood albumin levels (p=0.015). CONCLUSIONS: This study provides data on levels of heavy metals in a group of elderly people. Such information is very scarce. Associations with diseases should be the subject of further investigation.

BACKGROUND: There are few studies in the Czech Republic describing and evaluating the nutritional status of institutionalized elderly. METHODS: Data were collected from 659 women and 156 men aged 65 years and older and living in retirement homes in and around Prague. Data included: a Mini-Nutritional Assessment (MNA questionnaire), anthropometric measurements and biochemical evaluations. RESULTS: According to the MNA questionnaire, 10.2% of these elderly individuals were malnourished and 39.4% were at risk of malnutrition. More women than men were malnourished (OR = 0.59 and 95% CI 0.42-0.86). Mean BMI values were 25.5 for females and 27.5 for males. MNA was positively correlated mostly with immobility (r = 0.63; p < 0.001), BMI (r = 0.57; p < 0.001) and mid-arm circumference (r = 0.56; p < 0.001). Serum albumin levels were <28 g/l in 1.3% (1.3% of the women and 1.36% of the men) and between 29.0 - 34.0 g/l in 21% (22.5% of the women and 14.4% of the men). Statistically significant differences between groups according to MNA scores were found for albumin, prealbumin, transferrin and creatinine. Prevalence of smoking was significantly higher among males. CONCLUSION: The study results confirmed that institutionalized elderly, especially women, should be considered a nutritionally vulnerable population group that needs attention.

Whole blood selenium, copper, zinc and manganese concentrations of 197 institutionalized senior citizens (46 males, 151 females) aged 61-100 years (mean age 83.6 years) were determined using atomic absorption spectrometry and inductively coupled plasma mass spectrometry from two localities in the Czech Republic (Prague and Teplice) from 2009 through 2011. Geometric means (GM) of whole blood selenium (B-Se), copper (B-Cu), zinc (B-Zn) and manganese (B-Mn) levels were 74.0 µg/l, 941.0 µg/l, 5898.0 µg/l and 10.9 µg/l, respectively. Gender-related differences were found with significantly higher B-Cu levels in women and significantly higher B-Zn levels in men. The percentage of seniors with B-Se levels lower than 56 µg/l (which is equivalent to the critical value of 45 µg/l of Se in serum (S-Se)) was 8.6%. A negative correlation between age and B-Se levels was found. B-Zn positively correlated with serum albumin and prealbumin whereas a negative correlation between age and B-Zn was observed. Seniors with diabetes mellitus and atherosclerosis had higher B-Cu and B-Mn levels, respectively, than those without these diagnoses. The elderly from Prague had significantly higher B-Mn concentrations than those from Teplice. We found no evidence of serious essential elements deficiencies or excesses in the seniors who participated in this study.
