RESUMO
OBJECTIVES: The growing number of chronic conditions and functional limitations resulting from demographic changes and the aging of the population poses several challenges for health care and public health. Consequently, it plays a role in the assessment of the impact of diagnostic and treatment effects on patient satisfaction. The study aims to assess older patients' overall satisfaction with the medical care and healthcare system in Poland and to verify such factors as patient-doctor interactions, access to health care and other sociodemographic characteristics as possible determinants of patient satisfaction at the later stage of life. METHODS: The survey data represent the polish part of the cross-sectional COURAGE in Europe study. Satisfaction with hospital care, outpatient care, and the healthcare system in Poland was assessed. The indices for the psychosocial dimension of the patient-doctor relationships and access to hospital/outpatient care were developed based on patients' experiences as the possibility of talking about private matters, the clarity of explanations, the involvement in decision-making process, being treated respectfully, the duration of waiting and the ease of access to a preferred doctor or other healthcare professional. The ordered probit regression models were used. RESULTS: The psychosocial dimension of patient-doctor relationships was associated with the satisfaction with both hospital and outpatient care. Being treated with respect (very good experience vs. bad odds ratio [OR] = 8.1, 95% confidence interval [CI]: [1.9, 34.4]) and the possibility to talk about private matters with medical team (very good experience vs. bad OR = 3.5, 95% CI: [1.1, 10.4]) during the last stay in hospital were reflected in the higher satisfaction with the healthcare system. By contrast, the involvement of patients in the decision-making process (very good experience vs. bad OR = 3.6, 95% CI: [1.8, 6.7]) or access to outpatient health care (based on developed index OR = 1.02, 95% CI: [1.01, 1.02]) were found to be significant determinants of satisfaction with the healthcare system in Poland. Other factors associated with satisfaction with hospital stay were gender and changes in health conditions, whereas achieving the expected outcome was related to satisfaction with outpatient care, and the expenditure for medicines and medical services - to satisfaction with the heathcare system. CONCLUSION: The investigation confirms an important role of doctor-patient communication skills in improving older patient satisfaction and highlights the need for identifying the psychosocial dimension of patient-doctor relationships as an important part of health care.

N-glycan processing and assembly defects have been demonstrated in untreated and partially treated patients with Classical Galactosaemia. These defects may contribute to the ongoing pathophysiology of this disease. The aim of this study was to develop an informative method of studying differential galactose tolerance levels and diet control in individuals with Galactosaemia, compared to the standard biochemical markers. Ten Galactosaemia adults with normal intellectual outcomes were analyzed in the study. Five subjects followed galactose liberalization, increments of 300 mg to 4000 mg/day over 16 weeks, and were compared to five adult Galactosaemia controls on a galactose restricted diet. All study subjects underwent clinical and biochemical monitoring of red blood cell galactose-1-phosphate (RBC Gal-1-P) and urinary galactitol levels. Serum N-glycans were isolated and analyzed by normal phase high-performance liquid chromatography (NP-HPLC) with galactosylation of IgG used as a specific biomarker of galactose tolerance. IgG N-glycan profiles showed consistent individual alterations in response to diet liberalization. The individual profiles were improved for all, but one study subject, at a galactose intake of 1000 mg/day, with decreases in agalactosylated (G0) and increases in digalactosylated (G2) N-glycans. We conclude that IgG N-glycan profiling is an improved method of monitoring variable galactosylation and determining individual galactose tolerance in Galactosaemia compared to the standard methods.

OBJECTIVES: Healthy ageing (HA) is a key concept and highly desirable phenomenon in every ageing and already old societies. The aim of our study was to evaluate the influence of socio-economic conditions as well as life-style and other health-related factors on the WHO definition of HA. DESIGN, SETTING, PARTICIPANTS: The study used cross-sectional data of the PolSenior Project - nationwide research evaluating different aspects of ageing in Poland - which included 4'653 respondents aged 65 years and over. MEASUREMENTS: Data were collected by trained interviewers in respondents' homes. Three definitions of HA including or not the participants' chronic conditions were analyzed. RESULTS: The prevalence of HA appeared as high as 17.6% if none or 1 chronic disease was present and 42.8% if no information about chronic diseases was taken into account. The association between known health predictors (age, marital status, education, income) and HA was observed. Moreover, HA appeared in relation with indicators of physical functioning and lifestyle. There was a strong concordance between HA and the fair self-rated health (OR = 1.87; 1.99, and 2.74 for the 1st, 2nd and 3rd definitions, respectively) and opposite relation with self-reported need for help (OR = 0.15; 0.15; and 0.13, respectively). CONCLUSIONS: The HA definition based on no functional activity limitations, no cognitive impairment, no depressive symptoms, no more than one disease and being socially active seems to be a useful approach of HA.

This paper reports on the role of proteases secreted by roots in nitrogen capture by plants. The study was conducted on aseptically cultivated wheat seedlings (Triticum aestivum cv. Tacher) obtained from embryos isolated from grains. Seedlings were cultivated for 21 days on deionised water, Murashige Skoog medium (MS), MS without inorganic nitrogen (IN), and MS without IN, in which IN was replaced by casein (0.01%, 0.1% or 1%). Comparison of seedlings grown on these media showed that casein entirely compensated for the lack of inorganic nitrogen in the medium. Shoots and roots of seedlings cultivated on MS medium with this protein had higher fresh weight than those cultivated on MS medium without casein. The increase in fresh weight of seedlings was correlated with casein concentration and proteolytic activity in the medium. In conclusion, wheat that uses proteases secreted by the roots can directly utilise proteins in the medium as a source of nitrogen without prior digestion by microbial proteases and without protein mineralisation. These results suggest the important role of organic nitrogen fertilisers in increasing wheat yield.

Changes in self-rated health and its determinants have been analyzed in the group of 551 community-dwelling older age citizens of Krakow during the 12-year interval observation. Multidimensional model showed that changes in self-rated health between the studies have been significantly determined by such variables like age and self-evaluation of health status in the Ist study. Self-rated health was also less markedly decreased in men, who continued professional activity in the Ist study. Among variables analyzed in the IInd study it was age-related functional disability reported by men and reported chronic conditions that deteriorated self-rated health significantly. Changes in self-rated health between the Ist and the IInd study among women were determined by the same variables as in men (except for the continuation of professional activities in the Ist study). Significantly diminished scores were found in women with higher level of functional activity in the Ist study and greater independence in performing daily activities in the IInd study. Analysis of the summary effect of chronic diseases on self-rated health has shown significantly greater deterioration of self-rated health between the first and the second study related to the number of diseases reported in the Ist study.

Complex carbohydrates are rapidly becoming excellent biomarker candidates because of their high sensitivity to pathological changes. However, the discovery of clinical glycobiomarkers has been slow, due to the scarcity of high-throughput glycoanalytical workflows that allow rapid glycoprofiling of large clinical sample sets. To generate high-quality quantitative glycomics data in a high-throughput fashion, we have developed a robotized platform for rapid serum-based N-glycan sample preparation. The sample preparation workflow features a fully automated, rapid glycoprotein denaturation followed by sequential enzymatic glycan release, glycan purification on solid-supported hydrazide and fluorescent labelling. This allows accurate glycan quantitation by ultra-high performance liquid chromatography (UPLC). The sample preparation workflow was automated using an eight-channel Hamilton Robotics liquid handling workstation, allowing the preparation of almost 100 samples in 14 hours with excellent reproducibility and thus should greatly facilitate serum-based glyco-biomarker discovery.

The aim of the study was to assess the relation between health-related beliefs concerning the importance of risk factors in stomach cancer and positive health practices in eating habits. A multicentre hospital-based incident case-control study with 431 female stomach cancer cases aged less than 75 years and an equal number of age-matched controls without cancer has been carried out in Poland. The respondents were asked about their opinions on relevance in cancer prevention of such factors as protective role of raw vegetables and fresh fruit, consumption of fats, alcohol and coffee or using table salt. The data were compared with information on eating habits and diet behaviours in the reference group. It was shown in both groups that beliefs about the importance of raw vegetables and fresh fruit were closely associated with high frequency of everyday consumption of vegetables and fruit; however, statistically significant differences were found between cases and controls as regards the frequency of eating vegetables and fresh fruit at every meal. The same relation was observed between the belief in an unhealthy role of consumption of fats and using the animal fat in cooking. Univariate and multivariate analysis showed that a relation between beliefs and behaviours existed in the cases with the same demographic and social determinants.

A multicentre hospital-based incident case-control study with 520 male gastric cancer cases aged < 75 years and an equal number of age- and sex-matched controls without cancer has been carried out in Poland to assess potential risks due to smoking and alcohol consumption. It was shown that after adjusting for socio-demographic and dietary confounders and vodka drinking, smoking cigarettes had no significant effect on risk. The estimated relative risk (RR) increased to 2.27 (95% confidence interval [CI] : 0.97-5.28) for intestinal cardia cancer for those who smoked cigarettes without filters. The RR for stomach cancer grew as the frequency and amount of vodka drunk increased. People drinking vodka at least once a week had about a threefold higher risk compared to non-drinkers (RR = 3.06, 95% CI : 1.90-4.95). The effect of vodka drinking on risk was particularly strong for non-cardia cancers of the intestinal type. Those who usually drank vodka before breakfast had an elevated risk (RR = 2.98, 95% CI : 1.60-5.53) which was also present in all the subgroups investigated. Cardia and non-cardia cancer showed differences with respect to the interaction between tobacco smoking and vodka drinking. For cancers of the cardia region the risk was low for non-smokers or those who drank small amounts of vodka. The risk for cardia cancer increased considerably for smokers of cigarettes without filters and vodka drinkers who consumed large amounts (RR = 3.70, 95% CI : 1.13-12.06). For the non-cardia region a uniform increase could be observed for vodka drinking regardless of cigarette smoking status.(ABSTRACT TRUNCATED AT 250 WORDS)

In the framework of a nationwide case-control study of risk factors for stomach cancer, a household survey was conducted on those food habits at the family level which were considered relevant for stomach cancer. The practices of 741 case and 741 control households were compared and relative risks calculated by the unconditional maximum likelihood method. For each household, the person responsible for cooking completed the survey. Respondents to the household survey were 35% of the cases and 40% of the controls of the case-control study and otherwise other household members. Case households relied more frequently on their own gardens as a major source of vegetables and fruit, and they cooked their vegetables more often than control households. The vegetable and fruit consumption during the summer period per family member was significantly less in case households compared to control households. The difference in per capita vegetable and fruit consumption between case and control households persisted, but was considerably less pronounced when the consumption of the index person (case or control) was subtracted from the household consumption. The consumption of mainly wholemeal bread showed a relative risk (RR) of 0.18 (95% CI 0.07-0.44) compared with mainly white bread consumption, whereas frequent frying and stewing of meat was associated with an increased risk compared to boiling of meat (RR = 2.06, 95% CI 1.48-2.87). No association with risk was found for long-term refrigerator use or other storage modalities.(ABSTRACT TRUNCATED AT 250 WORDS)

The purpose of the study was to assess the importance of physical activity performed both in occupational settings and in leisure time on the risk of colorectal cancer, considering the possible confounding effects of dietary habits. The hospital-based case-control study was carried out in Poland. In total, 180 incident cases of colorectal cancer were recruited. An equal number of controls, individually matched by gender and age, were chosen from patients with no history of cancer. A food frequency questionnaire combined with quantity of foods eaten was used to assess the usual dietary pattern for 148 food items. The average physical load of the interviewed patients before the occurrence of disease was ascertained by self-assessment. The degree to which patients' recreational time was sedentary was measured by the number of hours spent watching TV. The adjusted risk of colorectal cancer was reduced by half in those active in leisure time (OR 0.45, 95% CI 0.24-0.84). The effect of occupational physical activity was of about the same order of magnitude in terms of risk reduction (OR 0.61, 95% CI 0.29-1.29) and both activities combined acted as independent protective factors. The protective effect of healthy nutrition appeared to be independent from that attributed to physical effort.

The purpose of the study was to assess the relation between the simultaneous exposure to alcohol and consumption of micronutrients that have protective properties against colorectal cancer. A hospital-based case-control study of colorectal cancer was carried out between January 1998 and November 1999 at the University Hospital in Krakow, Poland. In total, 180 incident cases of colorectal cancer, confirmed by histopathology, were recruited and an equal number of controls, individually matched by gender and age (+/-5 y), were chosen amongst patients with no history of cancer. A food-frequency questionnaire for 148 food items, combined with the quantity of foods eaten, was used to assess the normal dietary pattern. The data confirmed the reported inverse association between the intake of retinol, thiamine, or antioxidant micronutrients (vitamins C, E) and the occurrence of colorectal cancer. Alcohol intake was found to be an important risk factor for this cancer site, and the risk escalated in parallel with increased intake of retinol, carotene, vitamins C and E, but with high consumption of alcohol ran a noticeably high risk of colorectal cancer (OR= 6.79; 95% CI: 2.08-22.18). The risk was markedly lower, however, among alcohol drinkers who reported a high intake of micronutrients (OR = 1.35; 95% CI: 0.39-4.67). The data suggest that a combination of high consumption of alcohol and low intake of retinol and antioxidant vitamins may considerably increase the risk of colorectal cancer.

To investigate the risk of gastric cancer development in subjects with atrophic and nonatrophic gastritis, we studied 221 consecutive gastric cancer patients and 7647 non-cancer subjects for whom endoscopic biopsy of the gastric mucosa was available. In gastritis patients, the relative risk (RR) estimates of gastric cancer were as follows: corpus atrophic gastritis RR = 8.7 (95% CI = 5.4-14.1), antral atrophic gastritis RR = 4.5 (2.4-8.1), chronic atrophic pangastritis RR = 7.6 (3.8-15.3), corpus nonatrophic gastritis RR = 1.6 (0.9-2.7), antral non-atrophic gastritis RR = 1.2 (0.7-2.3), and pangastritis RR = 1.3 (0.6-2.8). The latter was of borderline significance (p = 0.07). In peptic ulcer, a significant excess risk was calculated for subjects with either corpus atrophic gastritis (RR = 3.1 [2.5-3.9] or antral atrophic gastritis (RR = 3.5 [2.6-4.8]). For stomach polyps, the risk was significantly increased only in subjects with corpus atrophic gastritis (RR = 2.1 [1.3-3.5]). The risks for both peptic ulcer and polyps, however, were significantly increased in chronic atrophic pangastritis. A substantial excess risk of gastric cancer was found for atrophy in the corpus (RR = 20.9 [9.0-48.9]) and in the antrum (RR = 14.9 [5.3-41.9]). An increased risk of peptic ulcer was also confirmed in subjects with atrophy in the corpus (RR = 3.0 [1.3-6.9]) and in the antrum (RR = 4.9 [2.0-12.1]).

Gross body composition studies done on a group of 11 women with cervical cancer before and after completion of radiotherapy revealed moderate compositional changes. There was after irradiation a tendency towards weight loss, connected with some increase of relative total body water content and also its extracellular fraction. The weight loss was due to a decrease of body fat and cell mass, whereas extracellular spaces tended to increase. There was a tendency towards a drop in plasma sodium concentration and an increase of its total content in extracellular water. A significant drop of the potassium serum concentration was observed.

The purpose of this study was to evaluate the functional status of the lower extremities (FSL) of elderly males from the community and to compare it with the self-assessment of health status (SHS) and ventilatory lung function based on measurement of forced expiratory vital capacity (FVC). The material covered a group of 559 males, age 65-89 years, who are residents of Krakow. The FSL was measured by the length of standing time on one leg (ST). There was a very strong declining trend in the ST with age in the elderly. The ST correlated significantly inversely with age (r=-0.32) and positively with FVC (r=0.29). The FSL was also associated strongly with the SHS score, while body-mass index (BMI) and occupational category (OC) appeared to have insignificant effect. The results of the study suggest that the ST may be used as a crude indicator of the general fitness of the elderly.
RESUMO
The objective of the study undertaken among the elderly was to assess the strength and importance of health variable predictors (ventilatory lung function, blood pressure) in comparison with that of sociodemographic variables (age, sex, education), smoking habit, obesity and health self-assessment. The study covered a sample of elderly inhabitants of Cracow (698 males and 1211 females) who attended the mass screening X-ray clinic. The sample examined did not include patients of old people's homes or geriatric wards. Statistical analysis of the relation between mortality over a 5-year period and chosen predictors was carried out with Cox proportional hazards model. It was found that besides age, forced expiratory volume in 1 s (FEV(1)) level is the strongest survival predictor among the elderly. Subjects who had better FEV(1) by 500 ml showed significantly lower death risk, by 18% in males and 27% in females after allowing for age and height. The results obtained confirmed the expectation that ventilatory lung function is one of the strongest predictors of survival in the elderly. In the sample studied, the impact of education, smoking habit, obesity, health self-assessment on mortality was not significant. The effect of hypertension appeared to be relevant only in the female group.
RESUMO
The haemadsorption reduction test with Ehrlich mouse ascites tumour cells proved to be a simple method for testing the sensitivity of influenza A virus strains to antiviral substances. Ribavirin and 2-deoxy-D-glucose were poorly effective in this system while all virus strains except A/PR/8/34 (H0N1) were highly sensitive to amantadine and rimantadine, the latter being the strongest inhibitor.

The sensitivities to amantadine and rimantadine of influenza A virus epidemic strains were assayed by the haem-adsorption reduction test in mouse Ehrlich ascites cells in comparison with prototype strains and a rimantadine-resistant mutant. Besides a majority of sensitive strains, two relatively resistant epidemic strains were identified. The possible origin of resistant strains and their importance for medical practice are discussed.

The purpose of the study was to present the dietary risk pattern in gastric and colorectal cancers, using the same methodological approach in a parallel hospital-based case-control study. In all, 180 cases of colorectal cancer and 80 cases of stomach cancer, confirmed histopathologically, were enrolled from the University Hospital in Cracow. A high intake of carbohydrates was associated with an increased risk of colorectal cancer (OR = 2.45). For stomach cancer, a moderate consumption of carbohydrates markedly increased relative risk (OR = 4.29), while a high intake of carbohydrates increased the risk by 8.73. The patterns of dietary risk factors related to intake of fats were definitively different in both cancer sites. The higher fat consumption was not associated with the higher risk of stomach cancer. A medium intake of fats increased the risk of colorectal cancer by 1.96 and that above 83 g/day by 2.20. In colorectal cancer, the significant protective effect of retinol, carotene and vitamin C has been evidenced, however, only carotene and vitamin E were inversely correlated with stomach cancer.

During a population survey in 1986/1987 among community-dwelling elderly in Cracow, aged 65 yrs and over, measurements of ventilatory lung function were carried out on 698 males and 1,211 females. The main objective of the study was to assess the importance of forced expiratory volume in one second (FEV1) as a predictor of survival experienced in this population group over a 6 year follow-up, in comparison with that of sociodemographic variables, smoking habit, chronic respiratory symptoms, hypertension, obesity and self-assessment of health. Statistical analysis of the relationship between mortality and chosen predictors has been performed with Cox proportional hazards statistical model. It was found that in addition to age, the FEV1 level was the most relevant and independent of age survival predictor among the elderly. In males, a reduction of FEV1 by 100 ml after allowing for age, showed a significantly higher risk of dying by 4%, (relative risk (RR) = 1.04; 95% confidence interval (CI) 1.01-1.06), and in females by 5% (RR = 1.05; 95% CI 1.05-1.09). Male current or ex-smokers displayed a higher mortality risk due to reduction of FEV1 (RR = 1.05; 95% CI 1.01-1.09) compared to lifetime nonsmokers (RR = 1.04; 95% CI 1.00-1.07); the corresponding RR values in women were 1.12 (95% CI 1.02-1.23) and 1.04 (95% CI 1.00-1.08), respectively. However, the differences found between the smokers and nonsmokers were not significant in either gender group. Other potential predictors considered, such as education, chronic respiratory symptoms, hypertension, self-assessment of health, or obesity, appeared to have been irrelevant in the multivariate analysis.

Studies of serum protein patterns done in a group of 42 patients with benign prostatic hyperplasia (PBH) revealed the following: (1) prior to the operation significant hypalbuminaemia and increase of alpha 2-, beta- and gamma-globulins, IgG, IgA, IgM and CRP levels; (2) 12 days after operation a marked decrease of albumin concentration, increase of alpha 2-globulin and a sharp rise of CRP; (3) after 1 year a decrease of hypalbuminaemia and increase of alpha 2- and beta-globulins and CRP; in contrast to that, there was further increase of gamma-globulin concentration expressed also in the IgG, IgA and IgM levels.
