An important part of the side effects of combined oral contraceptives (COC) usage is its psychological impact, which includes mood changes, anxiousness and depression. The psychological impacts are expected to be caused by physiological fluctuations of sex hormone levels during the menstrual cycle; this cycling is, however, suppressed in COC users. In our study, we assessed the differences in emotional awareness and anxiousness between women long term users of anti-androgenic COC (AA) and women with no COC use in their medical history (C). We also searched for intraindividual differences by comparing the results of both groups for the follicular and luteal phase of their cycle. A total of 45 women aged 18 to 22 participated in this study. The respondents were given our battery of questionnaires at the beginning of their follicular phase - this battery included two State-Trait Anxiety Inventory questionnaires (STAI-I, STAI-II), as well as a Levels of Emotional Awareness Scale (LEAS) test. The respondents were given only STAI-I in their luteal phase. We also analyzed the hormonal profile of our respondents. Our results show a significant difference in the LEAS analysis, implying the possibility of altered emotional awareness in AA group. STAI-I and STAI-II analysis did not yield any significant results, showing that anxiety levels of COC users probably do not differ from the general female population. We therefore discovered lower emotional awareness in COC using women (AA). Key words LEAS, STAI, Combined oral contraceptives, Anxiety, Hormonal profile.

Sports activity is generally considered to be beneficial to health. The World Health Organization (WHO) recommends physical activity as part of a healthy lifestyle. Sports activities significantly affect the cardiovascular system. A number of studies show that they significantly reduce the risk of cardiovascular disease as well as decrease cardiovascular mortality. This review discusses changes in various cardiovascular parameters in athletes - vagotonia/bradycardia, hypertrophy of heart, ECG changes, blood pressure, and variability of cardiovascular parameters. Because of its relationship to the cardiovascular system, VO2max, which is widely used as an indicator of cardiorespiratory fitness, is also discussed. The review concludes with a discussion of reactive oxygen species (ROS) and oxidative stress, particularly in relation to changes in the cardiovascular system in athletes. The review appropriately summarizes the above issues and points out some new implications.

Gastropathy is one of the most common diseases of the human gastrointestinal tract. Apart from its consequences in the stomach, it is also manifested in other parts of the digestive tract, particularly in the duodenum. The aim of this pilot study was to verify on animal model the empirically observed alleviation of gastropathy symptoms in patients who underwent a drinking treatment of Vincentka natural mineral water during their spa treatment. Sixteen male Wistar rats were included in the study. The animals were randomly divided into two groups: experimental group (E; n=8) and control group (C; n=8). The experimental protocol consisted of three phases: (1) handling phase (7 days); (2) mineral water (E)/tap water (C) administration (7 days); (3) acute gastritis induction (1 day). Twenty-four hours after the induction of acute gastritis, the animals were sacrificed. The collected tissues (stomach and duodenum) and blood were examined by standard histological microscopy, and by immunohistochemical and biochemical methods. Histopathological analysis revealed significantly reduced damage to the gastric mucosa in the experimental group. Significantly different values of blood plasma antioxidant capacity, oxidative stress parameters and blood plasma biochemical parameters were also found. Based on these results, we conclude that the mineral water Vincentka has a positive impact on development and symptoms of acute gastric ulcers.
Oral contraceptive pills (OCPs) have some strong advantages over more traditional types of contraception, including their consistently high contraceptive effect as well as multiple additional positive side effects. OCPs went through decades of intense pharmaceutical development and current formulas are well optimized - however, a handful of their negative side effects remain, including some that affect cardiovascular system, for example higher risk of hypertension, venous thromboembolism and increased arterial stiffness. The gold standard for arterial stiffness assessment is currently applanation tonometry, a method that relies on arterial pulse wave velocity measurement (PWV). Another possible method for arterial stiffness measurement is the use of the VaSera device, which measures cardio-ankle vascular index (CAVI). The aim of this study was to discover the effect of OCPs use on selected cardiovascular parameters related to arterial stiffness. We measured these cardiovascular parameters in the OCPs using group (OCP) and in the control group (CTRL) using applanation tonometer Sphygmocor and the VaSera device. Comparison of the data from both groups showed us significantly increased diastolic blood pressure (DBP) and carotid-radial pulse wave velocity (crPWV) as well as significantly lower subendocardial viability index (SVI) in the OCP. These results imply a negative effect of hormonal contraceptives on the cardiovascular system with most of the negative changes affecting the peripheral arteries. Despite this evidence supporting the hypothesis of OCPs having a negative effect on cardiovascular health, further research is necessary.

Diabetes mellitus 2 (DM2) is the seventh cause of death worldwide. One of the reasons is late diagnosis of vascular damage. Pulse wave velocity (PWV) has become an independent marker of arterial stiffness and cardiovascular risk. Moreover, the previous studies have shown the importance of beat-to-beat PWV measurement due to its variability among the heart cycle. However, variability of PWV (PWVv) of the whole body hasn't been examined yet. We have studied a group of DM II and heathy volunteers, to investigate the beat-to-beat mean PWV (PWVm) and PWVv in the different body positions. PWV of left lower and upper extremities were measured in DM2 (7 m/8 f, age 68+/-10 years, BP 158/90+/-19/9 mm Hg) and healthy controls (5 m/6 f, age 23+/-2 years, BP 117/76+/-9/5 mm Hg). Volunteers were lying in the resting position and of head-up-tilt in 45° (HUT) for 6 min. PWVv was evaluated as a mean power spectrum in the frequency bands LF and HF (0.04-0.15 Hz, 0.15-0.5 Hz). Resting PWVm of upper extremity was higher in DM2. HUT increased lower extremity PWVm only in DM2. Extremities PWVm ratio was significantly lower in DM2 during HUT compared to controls. LF and HF PWVv had the same response to HUT. Resting PWVv was higher in DM2. Lower extremity PWVv increased during HUT in both groups. PWVm and PWVv in DM2 differed between extremities and were significantly influenced by postural changes due to hydrostatic pressure. Increased resting PWVm and PWVv in DM2 is a marker of increased arterial stiffness.

Nutritional status, its assessment and its influence on numerous diseases is currently still being discussed. The aim of this study was to determine the current state of nutrition by various research methods in school children. Also, to verify the accuracy of body mass index (BMI) determination in school environment and to compare the nutritional status in two different types of school. We used a quantitative questionnaire method in 64 children from schools in the South Moravian Region. We have verified the weight and height measurement in the same group by sophisticated instruments. We have determined the basic parameters of the cardiovascular system (non-invasive continuously blood pressure recording; mutual spectral analysis for estimation of baroreflex sensitivity; applanation tonometry and cardiac polygraphy for arterial stiffness evaluation). The indicative questionnaire method encountered a problem with the weight of almost 40 % of the population approached - both obesity (14.3 %) and malnutrition (25.2 %). Cardiovascular parameters were in physiological range for the given age categories. We found increased values in BMI, % of body fat and heart rate in children from countryside type of school, respectively. We concluded that obesity/malnutrition are both common phenomena in the children population in the Czech Republic.

Anthracyclines represent one of the important classes of anti-cancer drugs; however, their major disadvantage is their profound cardiovascular toxicity. This study aimed to evaluate influence of anthracyclines on cardiovascular stiffness parameters estimated from pulse wave (PW). PW was measured in 59 cancer survivors treated with anthracyclines in childhood and in 248 healthy age-matched controls. Both patients and controls were divided into three age groups (13 - 15, 16 - 18 and 19 - 24 years). Central PW augmentation index (C-AI75) and augmentation pressure (C-AP75), both normalized to heart rate 75 bpm, were calculated as parameters of arterial wall stiffness. Central Buckberg sub-endocardial viability ratio (SEVR) was calculated as a parameter of diastolic function. Patients and controls were compared in each age group. C-AI75 and C-AP75 were significantly increased in patients in age groups 16 - 18 and 19 - 24 years. SEVR was decreased in patients in the oldest age group. Our results suggest that although toxic influence of anthracyclines to arterial wall and heart are developing during childhood and puberty, they can be detected rather in the adulthood. These changes are yet subclinical; however, their presence indicates potentially increased cardiovascular risk in childhood cancer survivors treated with anthracyclines during childhood.
