Effect of Primary Preventive Examination with Cardiorespiratory Fitness Test.

OBJECTIVE: The aim of this study was to explore the potential of free comprehensive primary preventive examination (CPPE) combined with cardiorespiratory fitness (CRF) test in terms of its attractiveness for general population and moreover to evaluate the induced behavioural changes. The main focus was on physical activity behaviour (PA). METHODS: In 2009-2013, 250 people (100 men, 150 women) aged 18-65 years were examined. CPPE included assessment of health status and lifestyle, CRF test and individualized counselling. Expectations, reasons and motivations for participating were recorded. The sample was evaluated in terms of age, gender, lifestyle, body mass index, body fat percentage, CRF, and health characteristics. Evaluation according to subjective benefits, perceived effects on health and lifestyle was performed after six months using electronic feedback questionnaires (FQ). Comparison was made within groups formed according to the reported increase in PA. RESULTS: People aged 18-39 years accounted for 72.8% of the sample; mean age 34.4±11.0 years; 40.0% were men. Behavioural and health risks were lower in comparison with the general Czech population, but at least 1 of 5 assessed risk factors was present in 88.8% (low fruit and vegetable consumption 74.8%, low physical activity level (PAL) 45.6%, smoking 19.6%, risky alcohol use 18.8%, and stress load 10.4%). The most represented category of CRF was "endurance-trained" (both genders). CPPE was perceived as a source of information concerning health, CRF and lifestyle. 40.0% of men and 30.7% of women were focused on improvement in CRF. The response rate of FQ was 75.6%. Individuals with low PAL and low CRF provided feedback less often (p<0.05). In terms of perceived effect, 84.1% of the respondents implemented some kind of behavioural change; 60.9% reported increase in PA, but only 38.1% reported maintaining improvement in PA after 6 months. A higher proportion of reported lasting changes in PA occurred in subjects who were overweight/obese and in those with low CRF. Participants with low PAL and higher number of lifestyle risks more likely increased their PA only temporarily. Improvement in PA was associated with reported changes in diet (p<0.001). In the group of respondents there was an increase in self-perceived PA (SPA) compared to the baseline (p=0.001). Moreover, individuals who reported increase in PA showed improvement in subjectively perceived health. CONCLUSION: The testing of CRF appears to be a promising motivating factor for going through the intervention, especially for younger people and men. CPPE is effective at the individual level in terms of providing information and initiating behavioural changes in PA. However, this type of intervention is less attractive and less effective for individuals with a higher behavioural risk profile.

Alcohol Consumption in Population Aged 25-65 Years Living in the Metropolis of South Moravia, Czech Republic.

OBJECTIVE: The aim of the study was to evaluate alcohol consumption in a representative sample of the population of the city of Brno, as part of research on cardiovascular risk factors. METHODS: Cross-sectional survey on a sample of 2,160 randomly selected residents 35-65 years old was carried out. For the invited volunteers who became a part of the investigation, alcohol consumption was determined in a controlled, face to face interview structured in accordance with a special questionnaire form. The frequency of alcohol consumption during the previous year was determined, in more detail during the last month (including quantification using "units of alcohol", their normal and maximum level of drinking, and any association between alcohol consumption and meals), and during the last week in the form of a complete, beverage specified and quantified 7-day recall period. Typical patterns of alcohol consumption were explored by the means of cluster analysis. RESULTS: During the past 12 months, 90.0% of the men and 79.0% of the women had consumed alcohol, the rest can be considered abstinent. The most commonly reported frequency was 2-4 times per week (35.6% of the men), or 1-3 times per month (22.8% of the women). Daily or almost daily consumption was reported by 24.8% of the men and 12.8% of the women. The number of units of alcohol consumed usually on one occasion amounts to an average of 3.88±4.80 for the men and 2.25±1.39 for the women, but the amount most often cited by both sexes was 2 drinks (36.4% of the men and 40.4% of the women). The largest amount consumed on any occasion during the last 30 days was 5 or more units in 69.3% of the men, and in 33.9% of the women it was 4 or more units (this amount of alcohol leads to a blood alcohol concentration (BAC) of 0.08, the border of drunkenness). In 19.9% of the men and 7.5% of the women, this border was exceeded more than 5 times in the past month. Only 14.7% of the men and 10.3% of the women reported that the majority of their alcohol consumption occurs with food; on the contrary, 64.3% of the men and 77.6% of the women drinkers drink it either always without food or only rarely with it. During the past week, 81.6% of the men and 63.4% of the women drank alcohol (p<0.001, chi-square). The average value of consumption for one man was 11.57±11.91 doses, and for one woman 4.68±6.38 doses per week (p<0.001, t-test). A total of 17.8% of the men exceeded the limit of 21 doses per week, and 7.4% of the women exceeded 14 doses/week. After converting the weekly consumption into the number of units of alcohol per week expressed in litres per year, the total average consumption was 5.01±6.36 litres; for the men 7.26±7.62 litres and for the women 3.02±4.08 litres of pure alcohol per person annually. Consumption during the week was not uniform (p<0.001, ANOVA), with the highest occurring on Saturday, followed by Friday. The men mostly drank beer (62.9% of the total volume of alcohol), the women wine (68.6%). The cluster analysis identified 5 clusters of respondents, based on a set of alcohol consumption variables, as follows: very heavy drinking (1.6% of the respondents who drink alcohol); heavy drinking (8.8%); binge drinking (6.3%); moderate drinking (31.1%); and occasional drinking (52.3%). CONCLUSIONS: The results show a relatively high consumption of alcohol in the examined group. The recommended weekly limits were exceeded by only a small portion, but that consumption had a binge character. Conversion into a form allowing comparison with conventional national statistics shows a significantly lower consumption than these reported statements. Overall, men consume significantly more alcohol than women.

PREVENTIVE TRAINING PROGRAMME FOR PATIENTS AFTER ACUTE CORONARY EVENT-- CORRELATION BETWEEN SELECTED PARAMETERS AND AGE GROUPS.

AIM: Interventional cardiovascular training programmes provide a prescription of optimal form and safe intensity. They are part of the second phase of cardiovascular rehabilitation which is a key point in the whole tertiary-preventive care for patients with coronary artery disease. The patients are hemodynamically adapted to a normal physical load, their aerobic capacity is gradually increased, and they learn principles of regular aerobic-resistance exercise. The aim of this study is to assess the impact of modified aerobic-resistance exercise on cardiorespiratory indicators in patients after acute coronary event, and evaluate the differences between monitored parameters in different age groups. METHODS: The study was conducted on a group of 106 patients (85% of men) of an average age of 60.4 ± 10.9 years, with left ventricular ejec- tion fraction of 57.4 ± 7.2%. All subjects went through an acute coronary event. The time elapsed between the occurence of a coronary event and the beginning of the training programme was 35 ± 8 days. In patients after coronary artery bypass grafting, the time passed was 50 ± 16 days on average. All patients received a two-month aerobic-resistance training with a frequency of three times a week. The length of a training unit was set to 100 minutes (out of which 60 minutes were allocated to individual aerobic training). RESULTS: A significant negative correlation between age and average values of monitored parameters was observed. Even though the values of all parameters are decreasing with increasing age, a shift towards higher values in all parameters occurred after completing the training programme. The study reveals that there are interindividual differences between the parameter values. Asignificant difference in individual parameters was found between different age groups. The result of the study shows that a given parameter could characterize each age group. Completing the interventional training programme also led to a significant increase of exercise tolerance (1.8 ± 0.3 vs. 2.0 ± 0.4 W/kg; p < 0.001) and of peak oxygen consumption (22.8 ± 4.5 vs. 25.9 ± 5.5 ml/kg/min, p < 0.001). CONCLUSION: Interindividual differences between the parameter values have been identified. This could be helpful in methodological conception of preventive training programmes for patients suffering from cardiovascular disease. The mutual connection between the parameter values and age groups does not relate only to a safer training intensity determination, but also to a more precisely targeted application of different training modalities in order to achieve an optimal final training effect.

Heavy metals in hair samples: a pilot study of anaemic children in Kazakhstan, Kyrgyzstan and Uzbekistan.

BACKGROUND: Heavy metals with their potential haematotoxic effect can contribute to the risks of anaemia in children in the Central Asian Republics (CAR), where burden and exposure to these metals is still not sufficiently known and reported. METHODS: Cross-sectional study was performed in Central Asian countries in hospitals in Kazakhstan, Kyrgyzstan and Uzbekistan with the aim to investigate the potential contribution of heavy metals to anaemia in children. In each country, 20 children were recruited, all were hospitalised with diagnosed anaemia. A sample of hair was taken from each child to assess the hair concentration of lead, cadmium and mercury. RESULTS: Relatively high levels of hair lead were observed, particularly in Kyrgyzstan. While lead and cadmium concentrations did not differ significantly among countries, mercury was lower in Kazakhstan than in Kyrgyzstan (p < 0.05) and Uzbekistan (p < 0.001). Hair lead and cadmium levels were significantly positively correlated (correlation coefficient = 0.51, p < 0.001). CONCLUSION: The results of this study showed higher than expected levels of hair lead, cadmium and mercury in anaemic children. Because iron deficiency anaemia is a major public health problem in CAR, further investigation of the extent of exposure to heavy metal and its contribution in iron deficiency anaemia in the region would be recommended.

Gerstmann-Sträussler-Scheinker syndrome with the P102L pathogenic mutation presenting as familial Creutzfeldt-Jakob disease: a case report and review of the literature.

Gerstmann-Sträussler-Scheinker syndrome is a rare autosomal dominant disease caused by a mutation in the prion gene, usually manifesting as progressive ataxia with late cognitive decline. A 44-year-old woman with a positive family history developed early personality and behavior changes, followed by paresthesias and ataxia, later associated with memory problems, pyramidal signs, anosognosia and very late myoclonus, spasticity, and severe dysexecutive impairment. Magnetic resonance showed caudate, mesio-frontal, and insular hyper-intensities, electroencephalography revealed generalized triphasic periodic complexes. A pathogenic P102L mutation in the prion gene was detected. Our case differed from classical Gerstmann-Sträussler-Scheinker syndrome by rapid progression, severe dementia, abnormal electroencephalography and magnetic resonance findings, which were highly suggestive of familial Creutzfeldt-Jakob disease.

FTLD-TDP with motor neuron disease, visuospatial impairment and a progressive supranuclear palsy-like syndrome: broadening the clinical phenotype of TDP-43 proteinopathies. A report of three cases.

BACKGROUND: Frontotemporal lobar degeneration with ubiquitin and TDP-43 positive neuronal inclusions represents a novel entity (FTLD-TDP) that may be associated with motor neuron disease (FTLD-MND); involvement of extrapyramidal and other systems has also been reported. CASE PRESENTATION: We present three cases with similar clinical symptoms, including Parkinsonism, supranuclear gaze palsy, visuospatial impairment and a behavioral variant of frontotemporal dementia, associated with either clinically possible or definite MND. Neuropathological examination revealed hallmarks of FTLD-TDP with major involvement of subcortical and, in particular, mesencephalic structures. These cases differed in onset and progression of clinical manifestations as well as distribution of histopathological changes in the brain and spinal cord. Two cases were sporadic, whereas the third case had a pathological variation in the progranulin gene 102 delC. CONCLUSIONS: Association of a "progressive supranuclear palsy-like" syndrome with marked visuospatial impairment, motor neuron disease and early behavioral disturbances may represent a clinically distinct phenotype of FTLD-TDP. Our observations further support the concept that TDP-43 proteinopathies represent a spectrum of disorders, where preferential localization of pathogenetic inclusions and neuronal cell loss defines clinical phenotypes ranging from frontotemporal dementia with or without motor neuron disease, to corticobasal syndrome and to a progressive supranuclear palsy-like syndrome.

The atherogenic index of plasma is increased by hormonal contraception.

BACKGROUND/AIMS: Oral contraceptives are known to induce secondary dyslipidemia. The aim of this study was to determine if hormonal contraceptives affect the new atherogenic index of plasma (AIP) = log[triglycerides (TG)/high-density lipoprotein cholesterol (HDL-C)] together with the total cholesterol/HDL-C (TC/HDL-C) and the apolipoprotein B/apolipoprotein A1 (apoB/apoA1) ratios. DESIGN AND METHODS: This study included 43 healthy women. Blood lipids, apoA1, apoB and the high-sensitivity C-reactive protein (hsCRP) concentration were examined before the start of hormonal contraception and after 3, 6 and 9 months of its regular use. AIP, the apoB/apoA1 ratio and the TC/HDL-C ratio were calculated. RESULTS: After 9 months of continued hormonal contraception, we found significantly increased levels of TC, HDL-C, low-density lipoprotein cholesterol (LDL-C), TG, apoA1 and apoB (p < 0.05 for all analytes). The TC/HDL-C and apoB/apoA1 ratios remained unchanged; however, the AIP and the hsCRP concentration increased significantly (p < 0.005 and p < 0.006). LDL-C increased slightly over the first three examinations (0, 3, 6 months), and the rest of the indices increased over the first two examinations (0, 3 months) and maintained stable values through the fourth examination (9 months). CONCLUSIONS: The increased AIP and hs-CRP concentration after 9 months of hormonal contraception demonstrate that contraceptive-induced dyslipidemia has a proatherogenic nature, even when the TC/HDL-C and the apoB/apoA1 ratios are unchanged.

The effect of breastfeeding and its duration on acute otitis media in children in Brno, Czech Republic.

AIM: We designed this study to assess the effect of breastfeeding and its duration on acute otitis media (AOM) in children of our geographical region. Our main aim was to determine the period of breastfeeding, necessary to achieve optimal preventive results against AOM. METHODS: The children that, according to the questionnaire, had suffered AOM infections in the past were used as the study group with the rest of the children used as control. The duration of breastfeeding was divided into months and the odds ratios for the occurrence of AOM were calculated for the children breastfed for more than or equal to a certain period, compared to the children breastfed for less than that period. This was repeated for each month separately and the results plotted on a graph of the confidence interval (CI) for the odds ratio values, against months of breastfeeding. RESULTS: The results of our study show that breastfeeding for a period of up to 11 months can play a significant preventive role against AOM (odds ratio and lower 90% CI > 1). Breastfeeding for longer periods of time is also beneficial, with breastfeeding up to 18 months being associated with some preventive effect against the disease (odds ratio > 1), but the reduction in the incidence of AOM is not statistically significant after the 11th month. Furthermore, there are marked differences in the importance of breastfeeding during the first 11 months, with a vital protective effect during the first 4 months of life which, however, drops by the 5th month and then rises again from the beginning of the 6th to the end of the 8th month. The protective effect then drops once more, although it remains positive and statistically significant until the 11th month of life and positive, but not statistically significant, until the 18th. CONCLUSION: Our study has revealed that for an optimal preventive effect to be achieved, the child should be breastfed for at least the first 11 months of its life. Continuing after this for up to the 18th month shows some preventive effect, which however is not statistically significant. Our results support the hypothesis that the importance of breastfeeding varies with the development of the child, its changing environment and to the new immunological challenges this brings.
