Studies on iodine content in daily diets, particularly elderly people's diets.

Poland represents moderate degree of severity of iodine deficiency. In 1997 a national program has been introduced of obligatory iodine prophylaxis including the iodination of household salt. In order to assess the extent of iodine consumption, the assessment were carried out on iodine content in average Polish diets with regard elderly people's diets. The aim of the study was also to analyse the composition of supplements allowed for trade in Poland, with regard to iodine content in these products. The assessment of iodine content in Polish diets was performed on the basis of the data of the household budgets and the data of iodine content in food products (without kitchen salt). The calculated iodine content in average Polish daily diets (adults and children) ranged from 40.4 microg to 50.7 microg. The iodine content in elderly people's diets was 75.5 microg/daily diets. In all studied diets the amount of iodine coming from food products, not taking into account iodinated salt, was insufficient for the realization of Polish RDA for this element. It shows that iodination of kitchen salt in Poland is necessary. Moreover on the Polish market exist supplements including iodine (20-200 microg iodine in tablet).

[Magnesium status in children and adolescents with celiac disease].

UNLABELLED: Magnesium deficiency has been reported in patients with classical coeliac disease. Classical coeliac disease has been recently very rare, but the frequency of the silent or latent form has increased. The aim of the study was to evaluate the magnesium status in patients with coeliac disease diagnosed according to ESPGAN criteria. 41 GFD(+) patients aged 6-18 years, who were on a gluten-free diet (GFD) for 2.8 to 17.3 years (mean 11 years); with normal villous structure and IgAEmA(-), and 32 GFD(-) patients aged 5-17 years, with villous atrophy and IgAEmA(+): 8--after 7/12-13/12 of gluten challenge, 4--with late onset of coeliac disease, 20--with silent coeliac disease. All of the children did not have any other disorders. Magnesium status was examined by using: an i.v. Mg-loading test (30 mmol/1.73 m2); Mg urinary excretion and Mg concentration in serum, erythrocytes, and in hair. Abnormal values in GFD(+) and GFD(-) patients were found in: Mg i.v. loading test (retention > 40%) in 20 vs 34%, serum Mg (< 0.7 mmol/l) in 7 vs 3%, erythrocytes Mg (< 1.8 mmol/l) in 20 vs 25%. The reversed statistically significant correlation was found between Mg retention and Mg urinary excretion (R = -0.293, p = 0.009). No other statistically significant correlations were found. CONCLUSION: The magnesium deficiency was present in all patients with classical coeliac disease, but only in 1/5 of patients with coeliac disease on a gluten-free diet and in 1/5 of patients with silent coeliac disease.

[Reasons for magnesium deficiency in children with coeliac disease].

UNLABELLED: Magnesium (Mg) deficiency is often noted in patients with coeliac disease (CD). The aim of the study was the analysis of the reasons of this deficiency in children with CD, diagnosed according to ESPGAN criteria. MATERIAL: The study was performed on 41 patients aged 6-18 years adhering to strict gluten-free diet GFD(+) for mean 11 years, with normal small intestine mucosa, and IgAEmA(-), and on 32 patients aged 5-17 years on gluten containing diet, with classical CD, silent CD or after gluten challenge--GFD(-). In this group the villous atrophy of the small intestine and IgAEmA(+) were observed. In 18 of these patients Mg deficiency was found using Mg-loading test (30 mmol/1.73 m2). METHODS: The following parameters were analysed: type of the disease, observance of gluten-free diet, sex, and living place. Mg, Ca, Na, protein, fat, and dietary fiber intake was assessed using food frequency questionnaire method, and steatorrhea using faecal fat excretion (g/24 h). RESULTS: The frequency of Mg deficiency was similar in both sexes, occasionally in children from small towns (4.5%), and more often in children from big cities (31.5%), and village (34.4%). Dietary Mg intake below RDA was observed in 23% of children from GFD(+) group, in 19% from GFD(-) one, and in 17.6% in children with Mg deficiency. Insufficient Mg intake was found in 18.2% of children from small towns, in 17.6% from big cities, and in 12.5% from villages; Ca in 36.6%, 58.8%, and 59.3%, and protein in 18.2%, 35.3%, and in 34.4% respectively. In all groups of children high intake of fat and Na was observed. Dietary fiber intake was within the recommended values. All children with classical CD had increased fat excretion (mean 25.9 g/24 h), in other patients it was within normal values [GFD(+) mean 1.95 g/24 h, in GFD(-) without diarrhoea 1.7 g/24 h. CONCLUSIONS: Magnesium deficiency in children with CD depends on the form of the disease, adhering to GFD, diarrhoea with steatorrhea, and/or low Mg intake with the diet.

Polyamines in cow's and sow's milk.

There were considerably interspecies, individual, lactation and age related variabilities in the concentration of spermidine and spermine in cow's and sow's milk. Concentration of spermidine was similar in cow's and sow's milk, whereas spermine level was higher in sow's milk. The level of spermine was higher than spermidine throughout the lactation in sow's milk, whereas spermine in cow's milk was secreted only at the beginning of lactation (collostrum and milk of the first month of lactation). The peak of spermidine and spermine concentration occurred in the collostrum and milk between the 1st and 3rd week of lactation in cow and sow, respectively. There was a significant positive relationship between milk yield and spermidine secretion in cow as well as between the number of piglets and milk spermidine concentration in sow.

Diagnostica--a Bayesian decision-aid system--applied to hypertension diagnosis.

"Diagnostica" is a Bayesian statistical tool designed to collect and store the patient's data, suggest a diagnosis, and explain the decision in terms of density distributions. The program is written in C language on MacIntosh support. It is described using the case study of differential diagnosis between essential and secondary hypertensions (i.e., fibrodysplastic renal artery stenosis, atheromatous renal artery stenosis, Conn's syndrome, nephropathy and pheochromocytoma). Seventeen experimental parameters were taken into consideration, all of them available during the first medical examination. The density distributions of all items were established from the ARTEMIS experimental database. Both a priori probabilities of different types of hypertension and loss coefficients are taken into account in the calculations. Diagnostica can be used in a "make diagnosis" mode or in an "edition" mode. In the first case it can serve a physician in everyday practice; in the second it becomes a tool for medical research.

[Nutritive value of daily food rations prepared in different regions of the country. III. The levels of calcium, phosphorus, magnesium, iron and potassium].

Studies on the content of macrominerals in daily diets reconstructed in 1988 on the basis of the analysis of family budgets in 1986 carried out by the Central Statistical Bureau were carried on. Two social groups i.e. manual and mental workers with medium income were considered. The diets were prepared for 5 regions (Warszawa, Lublin, Olsztyn, Poznań, Wrocław). According to the studies the requirements for calcium and magnesium were met in about 70% and those for iron in about 84%. The content of potassium in the diets was in the range of recommended allowances while the phosphorus exceeded the allowances by about 20-30%. The comparison of the presently studied diets with the ones from 1973, 1980, 1981 showed a lower degree of realization of the recommended intake of calcium and magnesium in 1986. The content of studied minerals in the diets was usually similar in all five regions.

[Nutritive value of daily food rations reproduced in different regions of the country. IV. Copper, zinc and manganese levels].

The content of copper, zinc and manganese in daily diets reconstructed in the laboratory in 1988 on the basis of data on the yearly food consumption in 1986 of two social groups (manual and mental workers) with medium income was determined. The diets were prepared for four regions of the country (Warszawa, Lublin, Poznań, Wrocław). It was found out that the content of copper and zinc in the diets in 1986 and the realisation of recommended dietary allowances for these minerals were lower than in 1973, 1980 and 1981. The degree of realization of the recommended intake of zinc and copper in diets from 1986 was on average 67% and 45% respectively. The content of manganese in the diets was in the range of recommendation. The content of microminerals in the diets was usually similar in the all studied regions of the country.
