At present, there are no generally accepted normative values for blood pressure (BP) in athletes under exertion. Objective: to determine the normative parameters of blood pressure in young elite athletes in a test with dosed physical activity. 500 (229 girls and 271 boys) young elite athletes of 14–17 (15.8 ± 1.5) years old were examined, members of the youth teams of the Russian Federation, different in static and dynamic sports. The control group consisted of 36 healthy adolescents of the same age who are not involved in sports. All subjects underwent bicycle ergometry according to the PWC 170 protocol with an initial load of 1 W/kg, followed by an increase in load every 3 minutes by 25 W until a pulse of 170 bpm was reached or fatigue, blood pressure was measured manually according to the method of N. S. Korotkov at the end of each stage of the load. For young elite athletes, the maximum values of systolic blood pressure (SBP) on the load were significantly higher than for their peers who were not involved in sports (185 ± 20 vs 154 ± 15 mm Hg; p < 0.001). In a sample with dosed physical activity, the parameters of the SBP in young elite athletes can reach up to 230 mm Hg with an adequate increase in heart rate (heart rate ≥ 170 bpm.).

Participants of the study ESSE-RF-2 and co-authors: Moscow: Konstantinov V. V., Pokrovskaya M.S., Efimova I.A., Sivakova O.V.; Krasnodar: Alekseenko S.N., Gubarev S.V.; Оmsk: Livzan M.A., Grishechkina I.A., Rozhkova M.Yu.; Republic of Karelia: Vezikova N.N., Skopec I. S.; Ryazan: Filippov E.V., Dobrynina N.V., Nikulina N.N., Pereverzeva K.G., Moseychuk K.A.Aim. Evaluate the prevalence, awareness, treatment, and control of hypertension among people aged 25-64 examined in 4 regions of the Russian Federation. Material and methods. Study materials were the representative selections of non-organized male (n=3000) and female (n=3714) inhabitants of aged 25-64 from 4 regions of the Russian Federation (Krasnodar region, Omsk region, Ryazan region, the Republic of Karelia), response rate>80%. Systematic stratified multilevel random election was formed with locality criteria (Kisch method). All the participants were interviewed using the standard questionnaire. The universal epidemiological methods and evaluation criteria were used. The study was approved by the local ethics Committee of National research center for preventive medicine. Participants signed informed consent. Hypertension was defined as an average systolic blood pressure (SBP)≥140 mmHg and/or average diastolic blood pressure (DBP)≥90 mmHg and/or antihypertensive therapy (AHT). The efficacy of treatment was the achievement of the target BP. Control group – patients with BP<140/90 mmHg. Results. Mean SBP and DBP were 128.7±0,3 mmHg and 82.8±0.1 mmHg, respectively, higher BP was detected among male (p<0,001). The prevalence of hypertension was 44.2% that was higher among males than females (49.1% vs 39.9%, р˂0.0005), the highest hypertension frequency was in the Ryazan region. The awareness of hypertension was higher among females than in males 76.8% vs 69.4%. There were more persons with hypertension grade 1 among those, who were not aware of the hypertension. Medications were taken by 65.5% of females and 41.8% of males.Angiotensin-converting enzyme inhibitors were received by 49.9% of patients, angiotensin II receptor antagonists by 30.9%, beta blockers – 29.5%, diuretics – 22.7%, calcium antagonists – 15.7%, centrally acting drugs – 3.3%, others – 0.2%. The lack of AHT intake was negatively associated with age, ischemic heart disease, urban life and hypo-HDL especially among males. Heart rate >80 per min in females increased by 1.7 times the probability of absence of AHT. The prevalence of effectively treated was 49.7% of the participants with hypertension. The associations between ineffective treatment and abdominal obesity, ischemic heart disease (males), age, rural type of settlement, obesity (females) were found. Only 24.9% of patients had control of the hypertension.Conclusion. The prevalence of hypertension in Russian Federation remains high. An important task of the medical community is to identify the disease at an earlier stage of its development, before the appearance of complications. This approach can reduce the period from the onset of high blood pressure to a visit to the doctor.

We studied the effect of experimenter expectations and different instructions in a balanced placebo design. 157 subjects were randomized into a 2 × 4 factorial design. Two experimenters were led to expect placebos either to produce physiological effects or not (pro- vs. antiplacebo). All subjects except a control group received a caffeine placebo. They were either made to expect coffee, no coffee, or were in a double-blind condition. Dependent measures were blood pressure, heart rate, well-being, and a cognitive task. There was one main effect on the instruction factor (p = 0.03) with the group “told no caffeine” reporting significantly better well-being. There was one main effect on the experimenter factor with subjects instructed by experimenter “proplacebo” having higher systolic blood pressure (p = 0.008). There was one interaction with subjects instructed by experimenter “proplacebo” to receive coffee doing worse in the cognitive task than the rest. Subjects instructed by experimenter “antiplacebo” were significantly less likely to believe the experimental instruction, and that mostly if they had been instructed to receive coffee. Contrary to the literature we could not show an effect of instruction, but there was an effect of experimenters. It is likely, however, that these experimenter effects were not due to experimental manipulations, but to the difference in personalities.

Traumatic brain injuries (TBI) represent a high impact public health problem due to a high rate of death , long term disability and occurrence especially in young adults. Despite several promising animal studies, several parameters were proposed as biological markers and were assessed for this aim. Our study proposes the study of the early biochemical changes in association to hematological parameters for severe TBI patients prognosis. 43 patients with acute TBI were included in study based on clinical, laboratory and imagistic findings. The severity of the TBI was established by Glasgow Coma Scale GCS 3-8. In all patients were evaluated hematologic parameters (Red blood cell count - RBC, Hematocrit, blood Hemoglobin, White blood cell - WBC, Platelet count and biochemical parameters (glucose, urea, creatinine, electrolytes). Outcome was expressed as Glasgow Outcome Scale (GOS), between 1-5. Values were compared to control group -15 cases. Significant early differences in body temperature, heart rate, and systolic blood pressure were observed in TBI group versus control (p[0.05). After correlation, laboratory findings significantly associated to severe outcome - GOS = 1, 2 - (p[0.05) were plasma Na decrease and significant glucose increase. An early increase of temperature and decrease of Na may predict a severe outcome in patients with acute TBI; association with shifts in heart rate and blood pressure, imposes aggressive treatment measures.

Background: The association between physical activity (PA) and arterial stiffness is particularly important in children with congenital heart disease (CHD) who are at risk for arterial stiffening. The aim of this study was to examine the association between objectively measured PA and arterial stiffness in children and adolescents with CHD. Methods: In 387 children and adolescents with various CHD (12.2 ± 3.3 years; 162 girls) moderate-to-vigorous PA (MVPA) was assessed with the “Garmin vivofit jr.” for 7 consecutive days. Arterial stiffness parameters including pulse wave velocity (PWV) and central systolic blood pressure (cSBP) were non-invasively assessed by oscillometric measurement via Mobil-O-Graph®. Results: MVPA was not associated with PWV (ß = −0.025, p = 0.446) and cSBP (ß = −0.020, p = 0.552) in children with CHD after adjusting for age, sex, BMI z-score, peripheral systolic blood pressure, heart rate and hypertensive agents. Children with CHD were remarkably active with 80% of the study population reaching the WHO recommendation of average 60 min of MVPA per day. Arterial stiffness did not differ between low-active and high-active CHD group after adjusting for age, sex, BMI z-score, peripheral systolic blood pressure, heart rate and hypertensive agents (PWV: F = 0.530, p = 0.467; cSBP: F = 0.843, p = 0.359). Conclusion: In this active cohort, no association between PA and arterial stiffness was found. Longer exposure to the respective risk factors of physical inactivity might be necessary to determine an impact of PA on the vascular system.

The aim of this study was to evaluate Cardio-Ankle Vascular Index (CAVI) and increased arterial stiffness predictors in patients with carbohydrate metabolism disorders (CMD) in the population sample of Russian Federation. Methods: 1617 patients (age 25–64 years) were enrolled in an observational cross-sectional study Epidemiology of Cardiovascular Diseases and Their Risk Factors in the Regions of the Russian Federation (ESSE-RF). The standard ESSE-RF protocol has been extended to measure the cardio-ankle vascular index (CAVI), a marker of arterial stiffness. Patients were divided into three groups: patients with type 2 diabetes mellitus (n = 272), patients with prediabetes (n = 44), and persons without CMD (n = 1301). Results: Median CAVI was higher in diabetes and prediabetes groups compared with group without CMD (p = 0.009 and p < 0.001, respectively). Elevated CAVI (≥9.0) was detected in 16.8% of diabetes patients, in 15.9% of those with prediabetes, and in 9.0% of those without CMD (p < 0.001). The factors affecting on CAVI did not differ in CVD groups. In logistic regression the visceral obesity, increasing systolic blood pressure (SBP) and decreasing glomerular filtration rate (GFR) were associated with a pathological CAVI in CMD patients, and age, diastolic blood pressure (DBP), and cholesterol in persons without CMD. Conclusions: the CAVI index values in the prediabetes and diabetes patients were higher than in normoglycemic persons in a population sample of the Russian Federation. Since the identified disorders of arterial stiffness in prediabetes are similar to those in diabetes, their identification is important to prevent further cardiovascular complications.

Abstract Background Endotracheal intubation and extubation may cause undesirable hemodynamic changes. Intravenous oxycodone has recently been introduced and used for relieving hemodynamic alterations in response to intubation, but there is insufficient information regarding its application in stabilizing hemodynamics during extubation in the patients emerging from general anesthesia. Methods One hundred patients, who had undergone assorted laparoscopic surgeries under general anesthesia, were randomly assigned to Control group (saline injection, 50 cases) and Study group (intravenous injection of 0.08 mg/kg oxycodone immediately after completion of the surgical procedure, 50 cases). Blood pressure, heart rate, blood oxygen saturation (SpO2) as well as blood concentrations of epinephrine, norepinephrine, and cortisol were recorded or measured immediately before extubation (T0), during extubation (T1), as well as one minute (T2), 5 min (T3), and 10 min after extubation (T4). In addition, coughing and restlessness, time of eye-opening, and duration from completing surgery to extubation as well as Ramsay Sedation Scale were analyzed. Results Blood pressure and heart rate as well as blood concentrations of epinephrine, norepinephrine, and cortisol were significantly higher in the Control group compared with the Study group at the time of extubation as well as 1, 5, and 10 min after extubation (P < 0.05). When the patients emerged from general anesthesia, 70 % of the Control group had cough, which was significantly higher than that of Study group (40 %, P < 0.05). Significantly higher number of patients manifested restlessness in the Control group before (40 %) and after extubation (20 %) compared with that in the Study group (20 and 2 %, respectively, P < 0.05). In addition, patients of Control group had lower Ramsay score at extubation (1.7 ± 0.7) as well as 30 min after extubation (2.4 ± 0.9) compared to that of the patients of Study group (2.2 ± 0.9, and 3.0 ± 0.8, respectively, P = 0.003 and 0.001). Conclusions Intravenous oxycodone attenuated alterations of hemodynamics and blood hormones associated with extubation during emergence from general anesthesia.

Redistribution of blood from the viscera to the peripheral vasculature is the major cardiovascular response designed to restore thermoregulatory homeostasis after an elevation in body core temperature. In this study, we investigated the role of the hypothalamic paraventricular nucleus (PVN) in the reflex decrease in renal blood flow that is induced by hyperthermia, as this brain region is known to play a key role in renal function and may contribute to the central pathways underlying thermoregulatory responses. In anesthetized rats, blood pressure, heart rate, renal blood flow, and tail skin temperature were recorded in response to elevating body core temperature. In the control group, saline was microinjected bilaterally into the PVN; in the second group, muscimol (1 nmol in 100 nl per side) was microinjected to inhibit neuronal activity in the PVN; and in a third group, muscimol was microinjected outside the PVN. Compared with control, microinjection of muscimol into the PVN did not significantly affect the blood pressure or heart rate responses. However, the normal reflex reduction in renal blood flow observed in response to hyperthermia in the control group (∼70% from a resting level of 11.5 ml/min) was abolished by the microinjection of muscimol into the PVN (maximum reduction of 8% from a resting of 9.1 ml/min). This effect was specific to the PVN since microinjection of muscimol outside the PVN did not prevent the normal renal blood flow response. The data suggest that the PVN plays an essential role in the reflex decrease in renal blood flow elicited by hyperthermia.

AbstractThis paper describes a 4-month pilot study that tested the suitability of a physical activity intervention for first graders (children aged 6 and 7 years) in a public school in Santiago, Chile. Teachers were trained to deliver the programme in the classroom during the school day. Teachers were surveyed to determine if this intervention fit within their curriculum and classroom routines and they reported in a focus group that it was suitable for them. All children actively participated in the programme and positive changes in their attitudes towards physical activity were observed by their teachers. Anthropometrics, blood pressure and hand grip strength were measured in the students. A significant reduction was observed in children with high waist circumference ≥ 90th percentile, and in mean systolic blood pressure. However, statistical power values for those comparisons were rather low. Anthropometry and hand grip strength were not modified. The latter calculations and the lack of a control group are showing the weaknesses of this pilot study and that further research with a larger sample size and an experimental design is strongly needed.
