Cílem studie bylo zjistit, zda typ osobní příčinné orientace (OPO) může predikovat hmotnostní úbytek u účastnic kurzů snižování nadváhy s aplikací kognitivně-behaviorální terapie. Sledování probíhalo 12 týdnů a respondentky (N = 333) byly během této doby dvakrát vyzvány k vyplnění českého standardizovaného tříškálového „Dotazníku osobní příčinné orientace“ (DOPO). Absolventky kurzu (ženy, které se zúčastnily 11-12 lekcí) v průběhu kurzu signifikantně (p < 0,001) snížily svoji tělesnou hmotnost o 7,6 %. Ve studii bylo u skupiny absolventek zjištěno několik významných korelací, které poukázaly na existenci vztahu mezi OPO a změnou tělesné hmotnosti. Byla zjištěna negativní korelace mezi vnější příčinnou orientací (EO) a vstupní hmotností a jejím úbytkem (p < 0,05) a pozitivní korelace mezi vnitřní příčinou orientací (IO) a vstupní hmotností (p < 0,05). Míra vnější OPO a hodnota vstupní hmotnosti mohou predikovat velikost hmotnostního úbytku, avšak pouze u absolventek kurzu, a nikoliv u celé skupiny žen vstupujících do kurzů snižování nadváhy.
Parabens are a group of chemicals used as preservatives in the food, cosmetic and pharmaceutical industries. They are known to possess estrogenic effects, and therefore have been classified as endocrine disruptors. In addition to the classical endocrine organs, other tissues have endocrine activity, including adipose tissue. Several chemicals are known to cause obesogenic effects, and parabens are currently being studied in this context. The aim of this study was to investigate the possible connections of paraben exposure and obesity. Blood plasma from 27 healthy women was collected during their menstrual cycle. Basal anthropometric measures, levels of parabens (methylparaben, ethylparaben and propylparaben), adipokines (adiponectin, adipsin, leptin, resistin and visfatin) and hormones affecting energy balance and metabolic health (c-peptide, ghreline, GIP, GLP-1, glucagon, insulin, PAI-1) were measured. A Kolmogorov- Smirnov test showed higher methylparaben and propylparaben levels in women with BMI 25-34.9 compared to those with BMI 18.5-24.9. Plasma levels of methylparaben as well as the sum of parabens were positively associated with the plasma adipsin levels. Negative associations for methylparaben were found for glucagon, leptin and PAI-1. In accordance with other experimental studies we observed important associations of methylparaben and hormones affecting energy balance and metabolic health, indicating its obesogenic potential., L.

Cíl: Cílem práce bylo posoudit, jak všeobecné sestry pečují o své zdraví. Zda se zabývají vlastní prevencí, zmapovat výskyt zdravotních problémů, jejich řešení a odhalit postoj všeobecných sester k rizikovým faktorům ohrožujících jejich zdraví. Metodika: Metodou průzkumu bylo dotazníkové šetření provedené v období listopad 2011 - leden 2012 v Bílovecké nemocnici a. s. a v Městské nemocnici v Odrách. Nestandardizovaný dotazník obsahoval otázky zaměřené na prevenci onemocnění, výskyt zdravotních problémů a postoje všeobecných sester k rizikovým faktorům ohrožující jejich zdraví. Výzkumný soubor tvořil 100 všeobecných sester. Výsledky: Všeobecné sestry navštěvují praktického lékaře jen při subjektivních potížích, nedodržují léčebný režim u běžných respiračních onemocnění, dané onemocnění přecházejí, nevystavují si pracovní neschopnost k doléčení, zdravotní problémy konzultují na pracovišti s lékařem nebo si zvolí léčbu sami. Dlouhodobým zdravotním problémem u všeobecných sester je bolestivost pohybového aparátu, pouze čtvrtina pravidelně sportuje a upevňuje si zdraví. Pracovní výkon sester je závislý na kvalitě odpočinku a na celkové fyzické a psychické kondici. Téměř všechny všeobecné sestry se cítí fyzicky i psychicky vyčerpané, polovina sester uvažovala o změně povolání z důvodu vysoké psychické zátěže a nespokojenosti s platem. Zdravotničtí pracovníci vědí, jakým způsobem ohrožují faktory návykové a faktory životního stylu délku a kvalitu života, přesto třetina sester pravidelně kouří a trpí nadváhou. Závěr: Povolání všeobecné sestry je velmi náročné a společensky nedoceněné. Všeobecné sestry by měli využít své kvalifikace a více se angažovat v oblasti prevence, poradenství v otázkách ochrany a upevňování zdraví., Aim: One of objectives of this work is to assess how the nurses take care of their own health and whether the nurses deal with their own prevention. Also, to do the mapping of prevalence of health problems, their solution and to detect the attitude of nurses to the risk factors that may be life threatening and have an impact to their own health. Methods: The survey method supporting this work was done by questionnaire in Bílovec Hospital a.s. and Municipal hospital in Odry in period November 2011 - January 2012. Unstandardized questionnaire included questions regarding the prevention of diseases, incidents of health problems and the attitude of nurses to the threatening factors influencing their health. The experimental group was made of 100 nurses. Results: The nurses attend their doctors only in case of subjective symptoms, they do not follow the treatment regime in case of common respiratory health problems, they often pass the illness as well as they do not want to be issued the sick leave to finish the treatment properly. Often, they discuss their health problems in the work place or they decide to cure themselves. The long-term health disorder among nurses is musculoskeletal pain due to the fact that only quarter of them strengthens their health by doing a sport activity regularly. Work performance of the nurses is dependent on the quality of their relaxation and overall physical and mental condition. Almost all nurses feel physically and mentally exhausted, half of them thought of career change due to the high mental stress and pay dissatisfaction. All healthcare professionals are aware of how the addictive and lifestyle factors threaten their life, yet one third of the nurses smokes regularly and is overweight. Conclusion: The profession of general nurse is very challenging and socially undervalued. The nurses should use their skills and qualifications to engage in prevention and counceling in the issues of health protection and its strengthening., and Silvie Madziová, Eva Janíková
Clusterin is a heterodimeric glycoprotein with wide range of functions. To further explore its possible regulatory role in energy homeostasis and in adipose tissue, we measured plasma clusterin and its mRNA expression in subcutaneous adipose tissue (SCAT) of 15 healthy lean women, 15 obese women (OB) and 15 obese women with type 2 diabetes mellitus (T2DM) who underwent a 2-week very low-calorie diet (VLCD), 10 obese women without T2DM who underwent laparoscopic sleeve gastrectomy (LSG) and 8 patients with T2DM, 8 patients with impaired glucose tolerance (IGT) and 8 normoglycemic patients who underwent hyperinsulinemic euglycemic clamp (HEC). VLCD decreased plasma clusterin in OB but not in T2DM patients while LSG and HEC had no effect. Clusterin mRNA expression in SCAT at baseline was increased in OB and T2DM patients compared with controls. Clusterin mRNA expression decreased 6 months after LSG and remained decreased 12 months after LSG. mRNA expression of clusterin was elevated at the end of HE C compared with baseline only in normoglycemic but not in IGT or T2DM patients. In summary, our data suggest a possible local regulatory role for clusterin in the adipose tissue rather than its systemic involvement in the regulation of energy homeostasis., J. Kloučková, Z.

Serum adipocyte fatty acid-binding protein (FABP-4) concentrations are linked to human obesity and other features of metabolic syndrome. Patients with Cushing's syndrome (CS) develop numerous features of metabolic syndrome due to chronic cortisol excess. Here we tested the hypothesis that chronically increased cortisol levels in CS patients may alter circulating levels of FABP-4. Fourteen patients with CS, 19 patients with simple obesity (OB) and 36 healthy control subjects (C) were included in the study. Serum FABP-4 concentrations were significantly higher in both CS and OB patients relati ve to C group, but they did not differ between CS and OB groups. In a combined population of all groups, serum FABP-4 levels correlated positively with BMI, body fat content, serum glucose, triglycerides, HbA1c and HOMA index and were inversely relate d to HDL-cholesterol, resting energy expenditure and freeT3 levels. We conclude that FABP-4 levels are significantly increased in both patients with simple obesity and obese patients with Cushing's syndrome. We suggest that increased FABP-4 concentrations in CS patients are rather due to their excessive fat accumulation and related metabolic abnormalities than due to a direct effect of cortisol on FABP-4 production., V.

The objective of this study was to measure plasma fibroblast growth factor 21 and 19 (FGF21 and FGF19) levels in patients with Cushing's syndrome (CS) and to compare it with those of lean control subjects (C) and patients with obesity (OB). Fourteen untreated patients with CS, 19 patients with OB and 36 controls were included in the study. Plasma FGF21 and FGF19 levels were measured by ELISA kits, other hormonal and biochemical parameters were measured by standard laboratory methods. Plasma FGF19 did not significantly differ among the studied groups. Plasma FGF21 levels were significantly higher in both CS and OB groups relative to C group but they did not differ between CS and OB groups. In a combined population of all three groups FGF21 levels positively correlated with BMI, waist circumference and percentage of total and truncal fat mass. Less prominent inverse relationship with these parameters was found for FGF19. Neither FGF21 nor FGF19 were significantly related to cortisol concentrations. Increased FGF21 concentrations in both patients with CS and OB relative to lean subjects suggest that excessive body fat and/or related metabolic abnormalities rather than direct effects of cortisol are responsible. In contrast neither obesity nor hypercortisolism significantly affected FGF19 concentrations., V. Ďurovcová ... [et al.]., and Obsahuje bibliografii a bibliografické odkazy
Obestatin is a recently discovered peptide produced in the stomach, which was originally described to suppress food intake and decrease body weight in experimental animals. We investigated fasting plasma obestatin levels in normal weight, obese and anorectic women and associations of plasma obestatin levels with anthropometric and hormonal parameters. Hormonal (obestatin, ghrelin, leptin, insulin) and anthropometric parameters and body composition were examined in 15 normal weight, 21 obese and 15 anorectic women. Fasting obestatin levels were significantly lower in obese than in normal weight and anorectic women, whereas ghrelin to obestatin ratio was increased in anorectic women. Compared to leptin, only minor differences in plasma obestatin levels were observed in women who greatly differed in the amount of fat stores. However, a negative correlation of fasting obestatin level with body fat indexes might suggest a certain role of obestatin in the regulation of energy homeostasis. A significant relationship between plasma obestatin and ghrelin levels, independent of anthropometric parameters, supports simultaneous secretion of both hormones from the common precursor. Lower plasma obestatin levels in obese women compared to normal weight and anorectic women as well as increased ghrelin to obestatin ratio in anorectic women might play a role in body weight regulation in these pathologies., H.

The article represents an overview of the development of Czech health promotion in the last two decades. Current “state of art” and health promotion in international context are mapped. Major behavioral risk factors are described and analybesity in comparison to EU countries. Their impact on the Czech population health is discussed in terms of relevant diseases. The authors conclude that a great risk for future development of health in the Czech Republic is a lack of health promotion institutional infrastructure that would enable development of needed and effective health promotion programmes., PhDr. Helena Hnilicová, Ph.D., Mgr.

The aim was to find the differences in ketogenesis initiation in the early period after the exercise in obese patients and to find if these changes may predict the weig ht loss during the physical activity program. 96 females were enrolled. A clamped heart rate test (CHR) was performed to establish comparable exercise intensity. Blood samples for beta hydroxybutyrate (BOHB) assessment were collected prior, immediately after and 60 min after the test. Patients underwent a three month fitness program. Anthropometric measurements (fat mass and biochemical parameters) were measured. An energy intake was monitored and comparable in all subjects. A significant increase of BOHB was found in 60 th minute after the test, when compared with initiation levels (BOHB1 vs. BOHB3; p=0.03). This increase correlates with % fat mass (R=0.196; p=0.02) and negatively with age (R= –0.147; p=0.05) and with weight reduction during the three-month program (R= -0.299; p=0.03). Serum BOHB increase after the single exercise may detect individuals with an ability to induce lipolysis in three-month program of physical activity for obese patients., M. Matoulek, S.
