Effectiveness of ongoing face-to-face anti-tobacco intervention in children with asthma.

Background: Interventions to help parents quit smoking may yield important benefits for children with asthma. Children's exposure to environmental tobacco smoke can be measured by reporting of an adult in the household and testing the child's biomarker, e.g., cotinine. Objective: The aim of the study was to assess the effectiveness of "face-to-face" intervention carried out since 2016 in families with children diagnosed with asthma 3 years after beginning the anti-tobacco intervention. Methods: This study was a follow-up to an interventional study that assessed the effectiveness of direct patient education versus educational leaflets alone about parental tobacco smoking. The patients with asthma (ages 4-17 years) enrolled in our original intervention study conducted in 2016 were under the care of the allergy outpatient clinic. The active group was individually educated about the harmful effects of environmental tobacco smoke on their children. The control group included patients and parents, among whom only leaflets were distributed. After 3 years of ongoing intervention, in patients from both groups, exposure to tobacco smoking was evaluated with a questionnaire addressed to parents and/or caregivers and measurement of cotinine in children's urine. The forced expiratory volume in the first second of expiration and fractional exhaled nitric oxide levels were measured. Results: Seventy participants completed the study: 37 in the active group and 33 in the control group. In the active group, 27% of the parents quit smoking entirely compared with 9.4% of parents in the control group. In the group of active intervention, a significant decrease in the cotinine level (p < 0 .001) and the number of cigarettes smoked daily were observed (p < 0.001) 3 years after the active intervention compared with values right after the intervention. In the control group, there were no significant changes in the above-mentioned parameters. Conclusion: "Face-to-face" intervention among families with smokers were effective and lowered cotinine levels in children with asthma and the number of cigarettes smoked assessed 3 years after the intervention.

IL-33 is associated with allergy in children sensitized to the cat.

BACKGROUND: Several studies suggest that early-life exposure to animal allergens constitutes a relevant risk factor for the development of allergic sensitization. OBJECTIVES: The aim of the present study was to determine the role of interleukin-33 in children sensitive to cat allergen with allergic rhinitis and/or asthma. METHODS: The study included 51 children aged 5-18 years, both sexes, allergic to cats. Sensitization to cat allergen was confirmed by skin prick tests or specific IgE. Children were evaluated for the presence of bronchial asthma, atopic dermatitis, allergic rhinitis. A questionnaire evaluating the occurrence of allergic symptoms in children after contact with the cat and dog was performed. Mothers completed a questionnaire regarding cat exposure: during pregnancy and having a cat at home. A blood sample was taken from all children to measure the level of IL-33 in the serum. RESULTS: Keeping a cat in the home, once in the past, or having a cat in the home during the mother's pregnancy, revealed a statistically significant relationship with IL-33 levels in the studied patients. Also, daily contact with a cat during pregnancy affected the level of IL-33. Higher levels of IL-33 were shown in people with hypersensitivity to cat and pollen allergens and cat and other animals. In patients with bronchial asthma higher levels of IL-33 were found than in patients without bronchial asthma. CONCLUSIONS: Increased serum levels of IL-33 is related with keeping cats during pregnancy and in early childhood and can be associated with the development of asthma in children.

The effect of passive smoking on exhaled nitric oxide in asthmatic children.

To date, some studies suggest that passive smoking (PS) may be an important determinant of FeNO levels in children but sill there is a need of investigations using objective methods of PS exposure. The aim of our study was to examine the effect of PS, measured by urine cotinine levels, on FeNO and lung function (FEV1) in allergic and non-allergic asthmatic children. METHODS: It was a prospective, non-interventional study. 140 children, aged 4-17, newly diagnosed with asthma were recruited into two study groups (exposed group, unexposed group), according to smoking exposure/unexposure based on the questionnaire. There was one study visit. Subjects underwent a medical history (including history of atopy), physical examination, spirometry, FeNO and urinary cotinine measurement. RESULTS: 70 individuals had been exposed to tobacco smoke. The patients exposed to tobacco smoke were characterized by statistically significantly higher urine concentration of cotinine, 10,80 ng/mL, than their counterparts who had not been exposed to tobacco smoke, 1,56 ng/mL (P = 0,019). In the group of individuals unexposed to tobacco smoke the mean value of FeNO was 34,99 ppb, while in the group of patient who had been exposed to tobacco smoke, the corresponding mean value was significantly lower, it amounted to 22,41 ppb (P = 0,001) (Table 1). As regards to FEV1 measurements, there were not any statistically significant differences by study groups unexposed/exposed to tobacco smoke (P = 0,179 and P = 0,074, respectively). FeNO levels (ppb) in the studied patients allergic to cat, grass or trees, exposed to tobacco smoke were significantly lower than in those children unexposed to tobacco smoke. Our results suggest a clinically important issue, that FeNO results should be interpreted in the context of environmental tobacco smoke exposure. Additionally allergy to cat dander, grass or tree may be potential confounding factor, which should be taken into consideration.

Components of metabolic syndrome in relation to plasma levels of retinol binding protein 4 (RBP4) in a cohort of people aged 65 years and older.

PURPOSE: Elevated plasma concentration of retinol binding protein 4 (RBP4) has recently emerged as a potential risk factor as a component of developing metabolic syndrome (MS). Therefore, this study aimed to analyse the relationship between components of MS and concentrations of plasma RBP4 in a population of subjects 65 years and older. METHODS: The study sample consisted of 3038 (1591 male) participants of the PolSenior study, aged 65 years and older. Serum lipid profile, concentrations of RBP4, glucose, insulin, C-reactive protein, IL-6, and activity of aminotransferases were measured. Nutritional status (BMI/waist circumference) and treatment with statins and fibrates were evaluated. Glomerular filtration rate (eGFR), de Ritis ratio, and fatty liver index (FLI), as well as HOMA-IR were calculated. RESULTS: Our study revealed a strong relationship between components of MS and RBP4 in both sexes: plasma RBP4 levels were increased in men by at least 3×, and in women by at least 4×. Hypertriglyceridemia was most strongly associated with elevated plasma RBP4 levels. Multivariate, sex-adjusted regression analysis demonstrated that chronic kidney disease [OR 1.86 (95% CI 1.78-1.94)], hypertriglyceridemia [OR 1.52 (1.24-1.87)], hypertension [OR 1.15 (1.12-1.19)], low serum HDL cholesterol [OR 0.94 (0.92-0.97)], and age > 80 years [OR 0.86 (0.81-0.90)] were each independently associated with RBP4 concentration (all p < 0.001). CONCLUSIONS: In Caucasians 65 years and older, RBP4 serum levels are associated with a number of components of MS, independent of sex and kidney function. Hypertriglyceridemia as a component of MS is most significantly related to RBP4 concentration.

Acute phase response in the primiparous dairy cows after repeated percutaneous liver biopsy during the transition period.

The aim of this study was to evaluate the acute phase response of dairy cows to repeated liver biopsy in order to estimate the safety of this procedure during the transition period. Liver biopsies (up to 1000 mg of liver tissue) were conducted twice a day, 7 days before expected parturition and 3 days after calving. The number of needle insertions for each biopsy was recorded and was dependent on the amount of obtained tissue. Blood samples were taken on day 7 before expected parturition, then on days 3, 4, 7 and 14 after calving. Body temperature was measured daily in all 30 cows from day 3 until day 14 after calving. The concentrations of haptoglobin, serum amyloid A, fibrinogen and interleukin-6 were determined in serum and plasma. In 16.7% of cows, the rectal body temperature rose by ≥ 0.5°C on the day after liver biopsy. Although the concentrations of haptoglobin, serum amyloid A and fibrinogen increased significantly after calving (p<0.01), there was no influence of the number of biopsies on the acute phase reaction and repeated biopsy during the transition period had no effect on body temperature. Therefore, the procedure may be regarded as safe for cows during the transition period.

Bioelectrical impedance phase angle as a prognostic indicator of survival in head-and-neck cancer.

BACKGROUND: Phase angle could be an alternative to subjective global assessment for the assessment of nutrition status in patients with head-and-neck cancer. METHODS: We prospectively evaluated a cohort of 75 stage iiib and iv head-and-neck patients treated at the Otolaryngology Department, Head and Neck Surgery, Medical University of Lublin, Poland. Bioelectrical impedance analysis was performed in all patients using an analyzer that operated at 50 kHz. The phase angle was calculated as reactance divided by resistance (Xc/R) and expressed in degrees. The Kaplan-Meier method was used to calculate survival. RESULTS: Median overall survival in the cohort was 32.0 months. At the time of analysis, 47 deaths had been recorded in the cohort (62.7%). The risk of shortened overall survival was significantly higher in patients whose phase angle was less than 4.733 degrees than in the remaining patients (19.6 months vs. 45 months, p = 0.0489; chi-square: 3.88; hazard ratio: 1.8856; 95% confidence interval: 1.0031 to 3.5446). CONCLUSIONS: Phase angle might be prognostic of survival in patients with advanced head-and-neck cancer. Further investigation in a larger population is required to confirm our results.

Why are dairy cows not able to cope with the subacute ruminal acidosis?

One of the largest challenges for the dairy industry is to provide cows with a diet which is highly energetic but does not negatively affect their rumens' functions. In highly productive dairy cows, feeding diets rich in readily fermentable carbohydrates provides energy precursors needed for maximum milk production, but simultaneously decreases ruminal pH, leading to a widespread prevalence of subacute ruminal acidosis. Maximizing milk production without triggering rumen acidosis still challenges dairy farmers, who try to prevent prolonged bouts of low ruminal pH mainly by proper nutrition and management practices. The animals try to avoid overeating fermentable feeds, as it causes negative consequences by disturbing digestive processes. The results of several experiments show that ruminants, including sheep and beef cattle, are able to modify some aspects of feeding behaviour in order to adjust nutrient intake to their needs and simultaneously prevent physiological disturbances. Particularly, such changes (e.g., increased preference for fibrous feeds, reduced intake of concentrates) were observed in animals, which were trying to prevent the excessive drop of rumen fluid pH. Thanks to a specific mechanism called "the postingestive feedback", animals should be able to work out such a balance in intake, so they do not suffer either from hunger or from negative effects of over-ingesting the fermentable carbohydrates. This way, an acidosis should not be a frequent problem in ruminants. However, prolonged periods of excessively decreased rumen pH are still a concern in dairy cows. It raises a question, why the regulation of feed intake by postingestive feedback does not help to maintain stable rumen environment in dairy cows?

Allergic Rhinitis and House Dust Mite Sensitization Determine Persistence of Asthma in Children.

OBJECTIVE: To specify clinical and immunological parameters of the mechanisms, which may lead to development of persistent asthma, or regression of the disease symptoms. METHODS: Eighty children with childhood asthma, diagnosed in the past by using the modified Asthma Predicted Index (mAPI), were divided into two groups: remission group and persistent group. There were 3 study visits (baseline, at 6 mo, and at 12 mo). Clinical remission of asthma was defined as the absence of asthma symptoms for at least 12 mo without treatment. The patients could switch from one group to another during the 12 mo of follow-up. Clinical, inflammatory, and immunoregulatory predictors of asthma remission/persistence were analyzed. RESULTS: The presence of mAPI criteria as well as house dust mite (HDM) allergy and allergic rhinitis at 7-10 y, were associated with a reduced prevalence of asthma remission. The increased eosinophil blood count in mAPI criteria was associated with a lower expression of CD25 positive cells. HDM allergy was associated with a higher fractional exhaled nitric oxide (FeNO) level (p = 0.0061) and higher expression of CD25CD71 (p = 0.0232). Allergic rhinitis was associated with a higher expression of PPAR (p = 0.0493) and CD25CD71 (p = 0.0198), and lower expression of glycoprotein A repetitions predominant (GARP). CONCLUSIONS: Persistence of childhood asthma was largely determined by the presence of allergic rhinitis and sensitization to HDM. Additionally, API criteria but not immunoregulation processes, were related to asthma persistence.

One-year follow-up of clinical and inflammatory parameters in children allergic to grass pollen receiving high-dose ultrarush sublingual immunotherapy.

BACKGROUND: In a previous double-blind placebo-controlled study, we analyzed a high-dose sublingual immunotherapy (SLIT) ultrarush protocol in asthmatic children monosensitized to grass pollen. In the present open-label study, we assessed the effect of SLIT on symptom score and nonspecific bronchial hyperreactivity in the same cohort followed for 1 subsequent year. METHODS: The study population comprised 35 children who were enrolled in our previous study. Placebo-treated patients were switched to active treatment; therefore, SLIT was administered for a further year to all patients. SLIT was considered effective if it reduced the severity of clinical symptoms and decreased the use of symptomatic medication. The effect of SLIT on nonspecific bronchial hyperreactivity (methacholine challenge test) was also measured. RESULTS: The symptom scores for asthma and rhinitis and medication score remained unchanged in the group who continued SLIT. We also observed further significant improvement in the results of the methacholine challenge test during the third year of treatment. CONCLUSIONS: High-dose ultrarush SLIT reduced the severity of allergic symptoms in the first 2 grass pollen seasons but continuously improved bronchial hyperreactivity in children with asthma, suggesting that SLIT should be continued despite the lack of further improvement in clinical symptoms.

Early exposure to unhygienic conditions and infections is associated with expression of different Toll-like receptors.

BACKGROUND: We have previously shown a lower prevalence of atopy in children living in foster homes than in children living with their parents. OBJECTIVES: In this study, we explored the associations between atopy and expression of Toll-like receptors (TLRs) 2, 4, 7 and 9 in the same groups of children. MATERIAL AND METHODS: We enrolled all the atopic children living in foster homes in Lodz, Poland and carefully selected, on the basis of age, sex, sensitization profile, clinical manifestation of allergy, and treatment, a similar number of nonatopic children living in foster homes, and a similar number of both atopic and nonatopic children living with their parents. Expression of TLRs 2, 4, 7 and 9 was analyzed in all children. RESULTS: Expression of TLR2 in foster care children was significantly higher in nonatopic children than atopic children (P = .047), while that of TLR7 and TLR9 was significantly higher in atopic children than in nonatopic children. Additionally, expression of TLR9 in nonatopic children in foster care was significantly lower than in nonatopic children living with their parents (P = .003).We also found that both groups of nonatopic children had a greater number of features characteristic of foster home children (poor living conditions in the first year of life) than atopic children. CONCLUSION: Our results may suggest that alternative mechanisms might underlie the in vivo regulation of the expression of different TLRs involved in the development of atopy.

Status of hydration assessed by bioelectrical impedance analysis: a valuable predictive factor for radiation-induced oral mucositis in head and neck cancer patients.

BACKGROUND: Apart from surgery, the methods of treatment of HNC are radiotherapy (RTH) and/or chemotherapy (CRTH/CHT). One of the most frequent and serious complications of RTH is oral mucositis (OM). There is a strict correlation between the inflammation and the status of hydration. The aim of the study was to evaluate the changes in hydration, occurring in the course of RTH, measured by means of bioelectrical impedance analysis (BIA) and to analyze them in correlation with the intensification of OM in HNC patients. PATIENTS AND METHODS: Data from 49 HNC patients (stages I-IV) were analyzed. All of them were irradiated using IMRT technique with the doses of 50-70 Gy. Oral mucositis (OM) was evaluated according to RTOG/EORTC guidelines. BIA was performed using ImpediMed bioimpedance analysis SFB7 BioImp v1.55. RESULTS: In the fourth week of RTH, 4-5 days before the occurrence of severe OM, it was found that patients with OM grade 3 or higher compared to OM grade 2 or lower had significantly: lower ICW% values (respectively, 53.02% vs 50.72%; p = 0.0047), higher: ECW%: (47.95% vs 46.92%; p = 0.0020), TBW% (respectively, 56.34% vs 51.06%; p = 0.0455), ECW/ICW (respectively, 0.96 vs 0.86; p = 0.0007) and ECW/TBW (respectively, 0.49 vs 0.46, p = 0.0033). CONCLUSION: Our study indicates that HNC patients undergo changes in hydration in the course of RTH. We have also confirmed that the intensification of OM leads to ICW decrease and the increase of ECW, TBW as well as ECW/ICW and ECW/TBW values.

Vitamin D inhibits pro-inflammatory cytokines in the airways of cystic fibrosis patients infected by Pseudomonas aeruginosa- pilot study.

BACKGROUND: Vitamin D plays an important role in inflammatory responses after antigen exposure. Interleukin-23 (Il-23) promotes Il-17-dependent inflammation during Pseudomonas aeruginosa (P. aeruginosa) pulmonary infection. We aimed to compare the ability of calcitriol and cholecalciferol to modulate the inflammatory response of the CF airways infected with P. aeruginosa. METHODS: This was a randomized, placebo-controlled, double-blind, cross-over trial. Twenty-three patients with CF (aged 6-19), chronically infected by P. aeruginosa were randomly assigned to: calcitriol group receiving 1,25(OH)2D 0,5 mcg daily or cholecalciferol group receiving cholecalciferol 1000 IU daily for three months. The levels of Il-23 and Il-17A in the exhaled breath concentrate (EBC) were measured. Calcium-phosphorus balance was also evaluated (serum concentration of calcium, phosphorus, 25OHD, parathormone (PTH) and calcium/creatinine ratio in urine). Data were analyzed using means of Stata/Special Edition, release 14.2. A level of P < 0.05 was considered statistically significant. RESULTS: The level of Il-17A in EBC significantly decreased in calcitriol group from 0,475 pg/mL (± SD 0,515 pg/mL) to 0,384 pg/mL (± SD 0,429 pg/mL) (p = 0,008); there was no change in cholecalciferol group (p = 0,074). The level of Il-23 in EBC did not significantly change in calcitriol group (p = 0,086); there was significant decrease in cholecalciferol group from 8,90 pg/mL (± SD 4,07 pg/mL) to 7,33 pg/mL (± SD 3,88 pg/mL) (p = 0,001). In calcitriol group serum phosphorus and PTH significantly decreased (p = 0,021 and p = 0,019 respectively), the concentration of calcium significantly increased (p = 0,001); there were no changes in cholecalciferol group. CONCLUSIONS: Both analogs of vitamin D revealed their anti-inflammatory effect and reduced the level of Il-17A and Il-23 in the airway of CF patients with chronic P. aeruginosa infection. We observed improvement in calcium-phosphorus metabolism after supplementation with calcitriol, without adverse effects. It is recommended to use vitamin D in CF patients.

Evolutionary conservation of the apolipoprotein E-C1-C2 gene cluster on bovine chromosome 18q24.

We have constructed a long-range restriction map spanning about 250 kb on bovine chromosome 18q24. Our results show that the apolipoprotein C2 (APOC2) gene is located about 25 kb from the APOE gene. Four putative CpG islands are also indicated in the map. Interestingly, a minisatellite located in the third intron of the human and mouse APOC2 genes was also found at identical position in the bovine gene and revealed high sequence identity comparing with the two corresponding sequences. By means of cosmid mapping, we further demonstrate that the APOE-APOC1-APOC2 gene cluster is evolutionary conserved in cattle.

Longitudinal changes in the intake of vitamins and minerals of elderly Europeans. SENECA Investigators.

OBJECTIVE: To assess longitudinal changes in intake of vitamins and minerals in elderly Europeans. DESIGN: Longitudinal study including the collection of dietary intake data in 1988/1989 and in 1993. SETTING: Baseline and follow-up data were collected from nine European towns: Belgium: Hamme (H/B); Denmark: Roskilde (R/DK); France: Haguenau (H/F) and Romans (R/F); Italy: Padua (P/I); the Netherlands: Culemborg (C/NL); Portugal: Vila Franca de Xira (V/P); Spain: Betanzos (B/E) and Switzerland: Yverdon (Y/CH). In four other towns dietary intake data were collected in 1993 only: Portugal: Coimbra (C/P); Poland: Marki (M/PL); Northern Ireland: Ballymoney-Limavady-Portstewart (BLP/NI/UK) and United States: Mansfield (Connecticut) (M/CT/USA). SUBJECTS AND METHODS: Using standardized methods, data were collected from a random sample of 658 elderly men and 731 women born between 1913 and 1918. Dietary intake data were collected by a validated modified dietary history method. RESULTS: A significant decrease in the median intake of vitamin B1, vitamin B2, vitamin B6, vitamin C or iron was observed in several towns and for most of these nutrients in H/B, R/DK, R/F and V/P. Over the 4-y follow-up period, the proportion of elderly people with nutrient intakes below the lowest European RDI's increased for various nutrients in most towns, whereas the nutrient density of the diet, especially for iron and vitamin C, decreased significantly only in a few towns. The proportion of elderly people taking nutrient supplements varied from less than 5% in H/B to 60% in R/DK. CONCLUSION: The observed decrease in intake of some vitamins and minerals in most of the participating towns, indicates an increased risk for malnutrition in elderly Europeans.

Energy and nutrients intake of elderly people living in the Warsaw region, Poland.

The dietary intake of energy, macronutrients, minerals and vitamins was studied in a group of elderly living in urban, suburban, and rural areas of Warsaw region, Poland. The study was conducted in spring 1999 and 298 persons, born between 1919-1924, randomly selected with criteria of age and place of living, were included. Dietary data were based on the 3-day food records. The energy and nutrients intake was calculated on the basis of tables of nutritive value of food products and compared to the Polish RDA's. Daily food rations of the subjects (except for men living in Warsaw) had an incorrect structure as well as insufficient energy content. The highest (i.e. almost 60% or higher) prevalence of intake lower than 2/3 of Polish RDA's was observed for calcium, magnesium, copper, vitamin B2 and vitamin C as well as for iron and vitamin B1 among women. The average intake of fat, cholesterol, and phosphorus was above recommended level. The differences related to area of living were less pronounced for men than for women. Women from suburban area were the most vulnerable group in respect to nutritional inadequacy.

Medicine use and supplementation practice among participants of SENECA Study.

OBJECTIVE: To assess six-year changes in medicine use and supplementation practice of elderly Europeans. DESIGN: Longitudinal assessment including two rounds of the SENECA STUDY: 1993 (first follow-up) and 1999 (final follow-up). Random sample of elderly born between 1913-1918, 284 men and 337 women in 1999. Data were collected in 10 small towns in 9 European countries by personal interview using standardized questionnaire. RESULTS: In the six-year period the percentage of subjects taking medicines increased significantly (81.3 vs. 87.6%), while supplement usage did not change (23.2 vs. 23.5%). In 1999 a greater percentage of participants took in long-term order (>or= 2 years) antihypertensive drugs (33% vs. 21%), diuretics (18% vs.12%), anticoagulants (17% vs. 5%)and nitroglycerine (13% vs. 6%). In 1999 the supplements more frequently taken were calcium (12% of all the subjects, 7% of men and 17% of women), vitamin D (10% of all the subjects, 6% of men and 14% of women) and ascorbic acid (10% of all the subjects, 8% of men and 13% of women). In the finale survey calcium supplements were taken by more respondents than in 1993 (12% vs. 8%). Medicine and food supplement use was more frequent by women than by man in both 1993 and 1999. CONCLUSIONS: The higher prevalence of using medicines with cardiovascular effects suggests an increase of cardiovascular problems with age. The higher frequency of calcium and vitamin D usage among women suggests that these nutrients are taken for preventing senile osteoporotic fractures.

Consumption of food products by the elderly living in different environments of the Warsaw region, Poland.

The aim of the study was to compare qualitatively the intake of food groups by the elderly living in urban and rural areas, with regard to the place of living and sex. Fifty-sex subjects in Warsaw and 142 in villages (born in 1919-24) participated in the study. A 3-day record method was used to collect nutritional data. The subjects living in Warsaw consumed more often milk, meat, fish, fruit and their products, as well as fats and oils. Less than 50% of the elderly living in either rural or urban areas ate eggs and fish. Consumption of fruit and its products was also low in the villages (47%). Meat and meat products were consumed more often by elderly men, whereas milk, fruit and their products were eaten more often by women (a rural area only). Consumption of specific food items also differed between the two analyzed living areas; milk, yoghurt and cheese were eaten more often by the residents of Warsaw, however, the intake of cream was significantly higher in the villages. The intake of red meat and meat products was similar, but poultry was included into the diet of 24% of the elderly in the rural area, significantly less than in Warsaw (34%). It also appeared that butter and mixed fats were more common among the elderly in Warsaw,whereas lard, pork fat and margarine were more popular in the villages. Food choice in the rural area was of poorer quality.

Life style characteristics associated with nutritional risk in elderly subjects aged 80-85 years.

A logistic regression model was applied to 627 elderly men and women, who participated in all three data collections of the SENECA study in 1989, 1993, and 1999, to test the hypothesis that nutritional status in 80-85 year old persons was related to functional and cognitive status, but not significantly affected by living arrangement. Additionally, the authors hypothesized that relationships between cognitive status and self-care ability, between self-care ability and living situation, and between cognitive status and living situation would be stronger with increasing age. Nutritional status was categorized as being well nourished (> or = 24) or at nutritional risk (<24) using the 18-item mini-nutritional assessment questionnaire (MNA). Diminished self-care ability was defined as inability to perform all 7 self-care items on the ADL instrument. Respondents were deemed to have possible cognitive impairment if they scored <24 on the MMSE test. Residence situation was categorized as either living alone, with spouse/partner, or with others. Nutritional risk was found to be associated with diminished cognitive status and diminished self-care ability, but not associated with living alone. Elderly people with diminished cognitive function and diminished self-care ability had a more than two times higher risk of being at nutritional risk. In addition, the strength of relationships between cognitive status and self-care ability, self-care ability and living situation, and cognitive ability and living situation all increased over time. In the oldest old lifestyle characteristics and functional ability appeared to be stronger predictors of risk for malnutrition than in younger adults.

The sequence of porcine apolipoprotein E (APOE) cDNA.

Porcine cDNA clones encoding apolipoprotein E (APOE) were isolated and sequenced. The porcine APOE cDNA sequence is 1122 bp in length and encodes a pre-protein of 317 amino acids. The inferred porcine amino acid sequence corresponds to the human APOE-4 isoform.

[Schizophrenia, schizophrenia-like disorders and delusional disorders in patients with anorexia nervosa: literature review and report of 3 cases]. / Schizofrenia, zaburzenia typu schizofrenii i urojeniowe u pacjentów z rozpoznaniem jadlowstretu psychicznego--przeglad pismiennictwa, prezentacja 3 przypadków.

The authors present the review of literature concerning schizophrenia, schizophrenia type and delusional disorders in patients with a lifetime diagnosis of anorexia nervosa (AN). The authors describe also 3 patients (2 cases of paranoid schizophrenia and 1 case of catatonic syndrome). The clinical features in all patients are discussed. In 1 patient the catatonic symptoms occurred within the context of AN, (perhaps due to metabolic disturbances) and in 2 other cases the psychotic features occurred after recovery from AN. The authors discuss the occurrence of psychotic features in AN, and the possible function of starvation and metabolic disturbances in their aetiology.
