Prevalence of diabetes and impaired fasting glucose in Poland in 2005-2014: results of the WOBASZ surveys

AIMS

To evaluate the prevalence of diabetes and impaired fasting glucose in Poland in 2013-2014 and to determine the temporal trends between 2003-2005 and 2013-2014.

METHODS

A questionnaire survey was conducted in a representative sample of Polish adults, complemented by anthropometric and fasting plasma glucose measurements. The research was part of the national cross-sectional WOBASZ study. Diabetes was assessed as self-reported or screened (fasting plasma glucose level ≥ 7 mmol/l, based on one blood sample).

RESULTS

In the years 2013-2014 among 5694 participants aged 20-74 years, 6.0% (95% CI 5.4-6.6) reported a previous diagnosis of diabetes (5.8% in women and 6.2% in men). In addition, 2.4% of the participants (95% CI 2.0-2.8) without a previous diagnosis of diabetes (1.8% of women and 3.1% of men) had a fasting blood glucose level ≥7.0 mmol/l in a single measurement. In a single measurement, 18.4% of the participants (95% CI 17.4-19.4; 13.2% of women and 23.8% of men) had impaired fasting glucose. The prevalence of dysglycaemia in the WOBASZ II study was significantly higher compared to the WOBASZ I study findings from 2003-2005, increased from 6.6% to 8.4% for diabetes and from 9.3% to 18.4% for impaired fasting glucose (after age and sex standardization to the 2013 Polish population).

CONCLUSIONS

The prevalence of diabetes in Poland is similar to that observed in other European populations and has increased significantly over the last decade.

P750Role of circulating endothelial cells post-heart transplantation

Background

The role of endothelial progenitor cells (EPC) in heart transplantation (HT) is not well defined. Thus, the aim of this study was to evaluate prospectively the dynamic changes of circulating EPC levels in relation to post-HT rejection risk.

Methods

There were 27 HT recipients who had EPC from peripheral blood quantified during 6 months follow-up after HT. Patients were monitored regularly, by right ventricular endomyocardial biopsy assessment, for cellular rejection (ACR) defined as grade ≥2 or an antibody-mediated rejection (AMR) characterized by histopathological changes recorded as AMR1H. The primary end-point was acute rejection, either AMR or ACR.

Results

ACR and AMR were observed in 7 (25.9%) and 6 (22.2%) subjects respectively. EPC levels, after logarithmic transformation, immediately post-HT were alike regardless of ACR status, however patients with lower EPC were at risk of AMR at 1 month (Table 1). On the other hand patients with a significant reduction of EPC at 1 month post-HT compared with HT were less likely to have either ACR or AMR (p=0.0003). During longer post-HT observation (12 months) patients had similar EPC levels regardless of the rejection events. Dynamic changes in EPC levels are presented in figure. Nonetheless, greater changes in EPC expressed by coefficient of variation were associated with the risk of either AMR or ACR compared to the participants without rejection (mean [lower–upper quartile]) 15 [13–18] vs 8 [5–13]; p=0.02) and (22 [14–26] vs 8 [5–13]; p=0.01) respectively.

Changes in EPC level post-HT

Conclusions

Early reduction of EPC levels was predictive of a lower risk of ACR or AMR. Greater dynamic changes of EPC during 6 months of observation were associated with a higher risk of rejection suggesting an important role of EPC in the pathological processes post-HT. Thus our findings suggest significant role of EPC post-HT with respect to rejection status.

The protein expression disorders of connexins (Cx26, Cx32 and Cx43)and keratin 8 in bovine placenta under the influence of DDT, DDE and PCBs

Polychlorinated biphenyls (PCBs), dichlorodiphenyltrichloroethane (DDT) and its metabo- lite, dichlorodiphenyldichloroethylene (DDE) can disturb the secretory function of the ovary and both contractions and secretory function of the uterus during the estrus cycle and pregnancy. Additionally, PCBs can pass through the placental barrier into allantoic and amniotic fluid. The presence of PCBs in these fluids is associated with higher frequency of spontaneous abortions and premature births in humans and animals. Therefore, the effect of PCBs, DDT and DDE on the connexins (Cx26, Cx32 and Cx43) and keratin 8 (KRT8) expression in bovine placentomes was investigated. The placentome slices from the second trimester of pregnancy were incubated with PCB153, 126, 77, DDT and DDE (each at doses of 1, 10 or 100 ng/ml) for 48 h. Then, the slices were stained using immunohistochemistry. The density of Cxs staining was measured with Axio- Vision Rel. 4.8 software in fetal-maternal connections and binuclear cells (BNC). None of the tested xenobiotics (XBs) affected the localization of Cxs and KRT8 in the fetal-maternal connec- tion area, but the XBs affected the density of Cxs in fetal-maternal connections and binuclear cells (BNCs). Depend on the doses, in fetal-maternal connections all used PCBs changed the protein expression of different Cxs, while in BNCs, all tested XBs except DDT increased the ex- pression of Cxs. None of investigated XBs affected on KRT8 expression. In summary, used XBs affect the expression of Cxs and change the quantitative relationships between them. Therefore, XBs can unfavorably influence function of the utero-placental barrier in cows.

Flow-injection amperometric determination of pesticides on the basis of their inhibition of immobilized acetylcholinesterases of different origin

Determination of the organophosphorus pesticides paraoxon, chlorpyrifos oxon, and malaoxon has been performed by a method based on inhibition of acetylcholinesterase (AChE) and amperometric detection in a flow-injection system with enzymes obtained from the electric eel (eeAChE) and Drosophila melanogaster (dmAChE) and immobilized on the surface of platinum electrode within a layer of poly(vinyl alcohol) bearing styrylpyridinium groups. dmAChE is more sensitive than eeAChE to inhibition by chlorpyrifos oxon and paraoxon. The sensitivity difference was largest for chlorpyrifos oxon (detection limit approx. 17 times lower), and practically none for malaoxon. Determination of the analytes in spiked river water samples by use of the dmAChE biosensor resulted in recoveries from 50 to 90 % for chlorpyrifos oxon at levels of 20 to 40 nmol L(-1), 50 to 100 % for paraoxon at 0.6 to 0.8 micro mol L(-1), and 140 to 190 % for malaoxon at 0.6 to 1.2 micro mol L(-1).

[Correlations between some features of social networks and treatment outcome in patients with schizophrenia three years after initial hospitalization]

There were studied correlations between some features of social networks of 56 DSM-III schizophrenic patients and "specific aims of treatment": insight, satisfaction of the treatment, compliance, motivation for the treatment and "outcome of treatment" in psychopathological and social level three years from the first admission. There were used Fallow-up Chart, Bizoń's Social Support Questionnaire, BPRS-LA scale and Social Assessment Scale (SAS). There were obtained statistically significant results concerning correlations between the type of support (concentrated, dispersed, and mixed) and the size of the extra-familiar network and the "specific aims" of treatment. This means that patients who have a mixed type of social support and a extended extra-familiar social network obtain better specific treatment aims as: motivation for treatment, co-operation in treatment, insight and a subjective satisfaction of treatment. There exists also significant correlation between some features of social network such as the range of network, the amount and localisation of support and the size of the extra-familiar network and the psychopathology level. The patients who get little support and those whose whole support is localised in family have higher level of negative symptoms measured with BPRS sub-scale. Patients of little range of the social network, including extra-familiar network show more positive symptoms three years after the first hospitalisation. There were found no correlations between the social network features and profession.

[Preliminary evaluation of health behavior in obese students from a selected group of Warsaw adolescents]

The aim of this study was to assess health behaviour in obese pupils aged 11-17 years in one of the districts in Warsaw. Self-assessment about own health, appearance and possibilities was also studied. Questionnaire studies were carried out in pupils with obesity and in a control group of pupils, with normal body weight. We found the biggest deficiency of health promoting behaviour in the field of physical activity and dietary habits. Differences between the two groups of pupils were statistically significant. Significant differences were also found in self-assessment concerning physical fitness and appearance. We did not find any differences between obese and non-obese pupils in health risk behaviour: alcohol drinking, tobacco smoking, frequency of injuries and in psychosocial indicators.

[Social networks of schizophrenic patients three years after the first psychiatric hospitalization. Differences between a group treated in psychosocial program and patients treated in an individual treatment program]

Social networks of 54 DSM-III schizophrenic patients were studied. There are differences between social networks of patients who took part in the psychosocial program (n = 23) and social networks of patients treated in individual treatment program (n = 31). Patients treated in the psychosocial program receive significantly more social support from their social networks and there are significantly more new relationships in their networks than in the networks of patients treated in individual treatment program.

Usefulness of acoustic studies on the differential diagnostics of organic and functional dysphonia

Phoniatric and acoustic examinations were carried out in a group of 30 patients with dysphonia, including 15 with organic type and 15 with functional type. A complex phoniatric assessment offered the possibility to differentiate between these two groups of pathological voices. This was achieved also on the basis of acoustic analysis of the voice by extracting characteristics such as: formant frequency, Fo and its range, percentage of noise in the analysed verbal text, mean and maximum values of jitter. The possibility of differential diagnosis of these two different types of dysphonia in acoustic studies was confirmed by clinical examinations. The acoustic studies presented can be regarded as a new approach to a fast and sufficiently precise method in the screening diagnostics of dysphonia conditioned by growth of the vocal fold mass.

[Paroxysmal atrial fibrillation as an integral part of sick (damaged) sinus syndrome]

In a studied group of 1727 subjects in 101 cases (of either sex) the sick sinus syndrome with MAS attacks++ was diagnosed on the basis of clinical and electrocardiographic criteria. The most frequent cause of the syndrome with paroxysmal atrial fibrillation was ischaemic heart disease. In 42 cases atrial pacing was applied measuring the time of own rhythm return after the end of pacing, and His bundle potentials were recorded. For practical reasons the patients were divided in two groups. Trials of treatment with atropine or isopropylnoradrenaline derivatives++ were undertaken in group A, and in group B antiarrhythmic++ drugs were used (beta-blockers, quinidine, isoptin etc). In group I (38 patients with striking bradycardia) a good therapeutic effect was observed after pharmacological treatment in 8 cases (21%). In group II (63 cases of the tachy-bradycardia syndrome) a good effect was observed in 11 cases (17.4%).
