The purpose of the study. This study aims to review the practice of the utilization of antihypertensive drugs of various pharmacological groups within the condition of the therapeutic hospital in Ukrainian and Egyptian patients, adherence to treatment in patients with hypertension in Ukraine and Egypt. Materials and methods. A study of 120 patients who were treated for hypertension II stage in a therapeutic hospital in Ternopil and Cairo was conducted. All subjects completed a questionnaire that included personal, socio-demographic, and medical data. The number and type of hypotensive drugs or drug combinations were analyzed. Results and discussion. Regarding the pharmacotherapy of hypertension the use of β-blockers among Ukrainian participants did not differ from Egyptian. The use of calcium channel antagonists was a little bit higher among Egyptians than Ukrainians. Diuretics were used more often by Ukrainians than by Egyptians. The use of ACEI/ARBs surpassed the use of all other classes of antihypertensives among both groups. Whereas the ACEI/ARBs use among Egyptians was lower than Ukrainians. In this study we conducted a determination of compliance which was defined as an act of adhering to the regimen of care recommended by the clinician and persisting with it over time. The majority of Ukrainian and Egyptian patients with hypertension do not always perform the doctor's prescription. The reason for the unfull implementation of medical prescriptions with the same frequency was called deficiency of funds and forgetfulness. Near 80% of Ukrainian respondents are ready to complete the prescription with understanding, however, 14% of the patients stated that they were not always ready to fulfill the prescription, and the smallest part of patients did not think it was necessary to follow the regularity of treatment and treatment regimen. We noted no significant difference in the adherence to antihypertensive therapy between Ukrainian and Egyptian participants. Early discontinuation of treatment and suboptimal daily use of the prescribed regimens are the foremost common facets of poor adherence to treatment as well as non-adherence to antihypertensive therapy correlates with a better risk of cardiovascular events. Conclusion. ACEI/ARBs are the most commonly used group of antihypertensive drugs among Ukrainian and Egyptian patients. The majority of Ukrainian and Egyptian participants with hypertension do not always perform the doctor's prescription. Only 50% had an objective reason for insufficient compliance

Comparison Of The Results

The aim – to investigate the profile of patients with the uncontrolled arterial hypertension who concomitantly take two or three antihypertensive products and to evaluate the results of BP control achievement in this population after therapy adjustment. Materials and methods. A total of 4113 patients with hypertension were invited to take part in TRIUMF-3 (antihypertensive therapy in Ukraine – optimization of blood pressure in focus) study, they were under the supervision of family doctors. Anamnestically all participants (average age – 64; 36.1 % – are men), at least 1 month before the study, took 2 or 3 antihypertensive drugs without sufficient effect. The average values of office BP were 172/99 mm Hg, in > 40 % of patients they exceeded 180/110 mm Hg. The drug of choice for further therapy for 4103 participants was fixed combination of perindopril arginine, amlodipine and indapamide – «Triplixam» (Servier, France). The follow-up period for each patient was 3 months. Patients visited doctors after 1-2 weeks, 2 and 3 months after the start of the study and the corresponding correction of therapy. Before and after 2 months, the indicator of adherence to treatment was assessed. The last analysis included a comparison of the results of TRIUMF-3 and TRIUMF-2 with patients who were under outpatient supervision by family doctors and cardiologists. Results and discussion. The prescription of the original triple fixed combination for 3 months was allowed by the gradually decrease of BP to ~ 130/80 mm Hg; SBP (systolic BP) on average by ~ 42, DBP (diastolic BP) – by ~ 19 mm Hg. Target levels: < 140/90 mm Hg reached 73.4 % of patients, and ≤ 130/80 mm Hg – 59.1 %. In most patients (70 %) during the study, the rate of high adherence to treatment increased from an average of 9.5 % to 46.4 %. Triple fixed combination of perindopril arginine, indapamide and amlodipine therapy was well tolerated. Conclusions. The use of an original triple fixed combination of perindopril arginine, indapamide and amlodipine by family doctors was accompanied by the achievement of target BP levels in more than 2/3 of patients with hypertension in whom the previous two- or three-component therapy was ineffective. The use of triple fixed combination of perindopril arginine, indapamide and amlodipine was effective in both groups of patients with hypertension observed in family doctors (TRIUMF-3) and cardiologists (TRIUMF-2). However, cardiologists used the largest doses of the drug almost twice as often, which led to more optimal BP control (≤ 130/80 mm Hg) in a larger group of patients: 69.7 % vs. 59.1 % in family doctors. Regular drug monitoring, antihypertensive efficacy, and ease of administration of a triple fixed combination of perindopril arginine, indapamide and amlodipine were likely to be determinants of increased adherence to treatment in most participants in both studies, 75 % to TRIUMF-2, and 70 % to TRIUMF-3. Moreover, the rate of high adherence during the 2-months follow-up period increased in both studies by almost 5 times.

History Of

The International Society of Hypertension and the World Hypertension League initiated a blood pressure screening study called May Measurement Month 2019 (MMM19) to improve the detection of elevated blood pressure (BP) and to assess BP control in patients with hypertension (HTN).Aim. To assess adherence to treatment of the hypertensive population according to MMM19 campaign in Russia.Material and methods. During May 2019, 5394 people from 21 regions of Russia took part in the screening. Participation was voluntary and did not imply gender restrictions; all subjects were over 18 years of age. During the screening, BP was measured three times using electronic and mechanical sphygmomanometers, as well as a questionnaire on the diabetes, history of cardiovascular events, smoking, and alcohol consumption was filled. Information was also collected on the date of last BP check and the administration of statins, acetylsalicylic acid and antihypertensive drugs. Data on height and body weight was obtained from respondents.Results. The analysis included data from 5274 participants aged 18 to 96 years (men — 1834 (34,8%)). Median age was 25 years, quartiles — 20 and 49 years. According to MMM19 data, the proportion of HTN patients in the Russian population was 31,9%, and with the exception of participants under 25 years old — 51,5%. Patients with HTN over 25 years old take antihypertensive therapy in 73,6%; 38,6% are characterized by irregular drug intake. Only 11,8% of men and 17,2% of women reach the target blood pressure <130/80 mm Hg. Only 20-30% of patients who used 4-5 antihypertensives reached the target BP level.Conclusion. According to MMM19 in Russia, only a third of high-risk patients measured BP over the past 12 months. There is also low adherence to antihypertensive therapy and inadequate control of HTN. Patients with HTN and a history of cardiovascular events are more likely to take antihypertensives regularly.

SummaryThe plasma tissue factor (TF) concentration was correlated to factor VII concentration (FVIIag) and factor VII activity (FVIIc) in 498 healthy volunteers ranging in age from 17 to 64 years. Immunoassays using monoclonal antibodies (mAbs) were developed for the determination of TF and FVIIag in plasma. The mAbs and the test systems were characterized. The mean value of the TF concentration was 172 ± 135 pg/ml. TF showed no age- and gender-related differences. For the total population, FVIIc, determined by a clotting test, was 110 ± 15% and the factor VIlag was 0.77 ± 0.19 μg/ml. FVII activity was significantly increased with age, whereas the concentration demonstrated no correlation to age in this population. FVII concentration is highly correlated with the activity as measured by clotting assay using rabbit thromboplastin. The ratio between FVIIc and FVIIag was not age-dependent, but demonstrated a significant difference between men and women. Between TF and FVII we could not detect a correlation.

Deformation Diagrams

Problems when calculating reinforced concrete structures based on the concrete deformation under compression diagram, which is presented both in Russian and foreign regulatory documents on the design of concrete and reinforced concrete structures are considered. The correctness of their compliance for all classes of concrete remains very approximate, especially a significant difference occurs when using Euronorm due to the different shape and sizes of the samples. At present, there are no methodical recommendations for determining the ultimate relative deformations of concrete under axial compression and the construction of curvilinear deformation diagrams, which leads to limited experimental data and, as a result, does not make it possible to enter more detailed ultimate strain values into domestic standards. The results of experimental studies to determine the ultimate relative deformations of concrete under compression for different classes of concrete, which allowed to make analytical dependences for the evaluation of the ultimate relative deformations and description of curvilinear deformation diagrams, are presented. The article discusses various options for using the deformation model to assess the stress-strain state of the structure, it is concluded that it is necessary to use not only the finite values of the ultimate deformations, but also their intermediate values. This requires reliable diagrams "s–e” for all classes of concrete. The difficulties of measuring deformations in concrete subjected to peak load, corresponding to the prismatic strength, as well as main cracks that appeared under conditions of long-term step loading are highlighted. Variants of more accurate measurements are proposed. Development and implementation of the new standard GOST "Concretes. Methods for determination of complete diagrams" on the basis of the developed method for obtaining complete diagrams of concrete deformation under compression for the evaluation of ultimate deformability of concrete under compression are necessary.

Цель - изучение сывороточных уровней LIF, sLIr и их соотношение с гемодинамическими параметрами (ЧСС, САД, ДАД, ПАД, ЦАД, срАД, УО, МОК, ОПСС, СПВ) и содержанием вазоактивных веществ (AT II, ET-1, NO, ADMA, SDMA, eNOS, iNOS, NT-proСNP, NT-proBNP) у пациентов с эссенциальной артериальной гипертензией (ЭАГ) II стадии. Методы: количество LIF, sLIF-R/gp190 и вазоактивные вещества в сыворотке определяли иммуноферментным методом. Результаты: у пациентов с ЭАГ II стадии вне зависимости от проведения гипотензивной терапии была более высокая концентрация LIF (7,54 (2,8) пг/мл, 7,5 (2,1) пг/мл), по сравнению с условно здоровыми - 1,25 (0,5) пг/мл, р<0,001. При этом у пациентов, не получавших гипотензивные препараты, увеличивался уровень sLIr - (5800 (1470 pg/ml)) по сравнению с больными на фоне гипотензивной терапии (4100 (1380) пг/мл, р<0,001) и условно здоровыми (3800 (1100) пг/мл, р<0,001). При уровне sLIF-R выше 4800 пг/мл обнаруживали связь с увеличением содержания в сыворотке iNOS, NT-proBNP, ADMA, SDMA, (r = 0,5-0,8, р<0,05-0,001) и уменьшением уровня eNOS (r = -0,56-0,86, р<0,05-0,001), что соответствует прогрессированию заболевания. Корреляции между LIF и указанными вазоактивными веществами выявлено не было, что дает основание предполагать, что sLIFr вызывает собственные патогенетические эффекты помимо антагонистической активности по отношению к LIF. Aim. To study levels of serum LIF and sLIF-R and their correlations with hemodynamic parameters (heart rate, systolic BP, diastolic BP, pulse pressure, central BP, mean BP, stroke volume, total peripheral resistance, and pulse wave velocity) and vasoactive substances (AT II, ET-1, NO, ADMA, SDMA, eNOS, iNOS, NT-proСNP, and NT-proBNP) in patients with stage II essential arterial hypertension (EAH). Methods. Serum levels of LIF and sLIF-R/gp190 were measured using ELISA in 180 patients with stage II ЕAН. Results: Patients with EAH II (with or without antihypertensive therapy) had higher serum levels of LIF (7.54 (2.8) pg/ml and 7.5 (2.1) pg/ml, respectively) compared to healthy individuals (1.25 (0.5) pg/ml), р<0.001. Patients not receiving a therapy had higher serum levels of sLIF-R (5800 (1470 pg/ml) than patients receiving antihypertensive drugs (4100 (1380) pg/ml, р<0.001) and healthy individual (3800 (1100) pg/ml, р<0.001). In patients with EAH, sLIF-R levels higher than 4800 pg/ml correlated with increases in iNOS, NT-proBNP, ADMA, and SDMA (r = 0.5-0.8, р<0.05-0.001) and decreases in eNOS (r = -0.56-0.86, р<0.05-0.001), which corresponded to disease progression. LIF did not show any significant correlations with these vasoactive substances, which suggested that sLIF-R exerted its own pathogenetic effects besides antagonizing LIF. Generally, this trend was typical for patients with EAH (II stage) without antihypertensive therapy.

The Relationship

Background/Aim. The vertical dimension of occlusion is a very important parameter for proper reconstruction of the relationship between the jaws. The literature describes many methods for its finding, from the simple, easily applicable clinically, to quite complicated, with the use of one or more devices for determination. The aim of this study was to examine the possibility of determining the vertical dimension of occlusion using the vocals ?O? and ?E? with the control of values o btained by applying cognitive functions. Methods. This investigation was performed with the two groups of patients. The first group consisted of 50 females and 50 males, aged 18 to 30 years. In this group the distance between the reference points (on top of the nose and chin) was measured in the position of the mandible in the vertical dimension of occlusion, the vertical dimension at rest and the pronunciation of the words ?OLO? and ?ELE?. Checking the correctness of the particular value for the word ?OLO? was also performed by the phonetic method with the application of cognitive exercises when the patients counted from 89 to 80. The obtained difference in the average values i n determining the vertical dimension of occlusion and the ?OLO? and ?ELE? in the first group was used as the reference for determining the vertical dimension of occlusion in the second group of patients. The second group comprised of 31 edentulous persons (14 females and 17 males), aged from 54 to 85 years who had been made a complete denture. Results. The average value obtained for the vertical dimension of rest for the entire sample was 2.16 mm, for the word ?OLO? for the entire sample was 5.51 mm and for the word ?ELE? for the entire sample was 7.47 mm. There was no statistically significant difference between the genders for the value of the vertical dimension at rest, ?ELE? and ?OLO?. There was a statistically significant difference between the values f or the vertical dimension at rest, ?OLO? and ?ELE? for both genders. There was a statistically significant correlation between the value for the vertical dimension at rest, ?OLO? and ?ELE?, for both groups of subjects. Conclusion. Determining the vertical dimension of occlusion requires 5.5 mm subtraction from the position of the mandible in pronunciation of the word ?OLO? or 7.5 mm in pronunciation of the word ?ELE?.

Abstract Background Modern built-in spectrophotometer software supporting mathematical processes provided a solution for increasing selectivity for multicomponent mixtures. Objective Simultaneous spectrophotometric determination of the three naturally occurring antioxidants—rutin(RUT), hesperidin(HES), and ascorbic acid(ASC)—in bulk forms and combined pharmaceutical formulation. Method This was achieved by factorized zero order method (FZM), factorized derivative method (FD1M), and factorized derivative ratio method (FDRM), coupled with spectrum subtraction(SS). Results Mathematical filtration techniques allowed each component to be obtained separately in either its zero, first, or derivative ratio form, allowing the resolution of spectra typical to the pure components present in Vitamin C Forte® tablets. The proposed methods were applied over a concentration range of 2–50, 2–30, and 10–100 µg/mL for RUT, HES, and ASC, respectively. Conclusions Recent methods for the analysis of binary mixtures, FZM and FD1M, were successfully applied for the analysis of ternary mixtures and compared to the novel FDRM. All were revealed to be specific and sensitive with successful application on pharmaceutical formulations. Validation parameters were evaluated in accordance with the International Conference on Harmonization guidelines. Statistical results were satisfactory, revealing no significant difference regarding accuracy and precision. Highlights Factorized methods enabled the resolution of spectra identical to those of pure drugs present in mixtures. Overlapped spectra of ternary mixtures could be resolved by spectrum subtraction coupled FDRM (SS-FDRM) or by successive application of FZM and FD1M.

Abstract Background Entecavir (ENT) is an antiretroviral agent prescribed for treatment of HBV and HIV. Objective Development and validation of three simple, sensitive, selective, and precise methods for determination of ENT in presence of its oxidative degradation product (ENT deg.). Methods The first method was based on second derivative (D2) spectrophotometry through measuring the peak amplitude of D2 spectra at 293.6 nm. The second one is mean centering of the ratio spectra (MCR), which allowed measuring the peak amplitude at 280.0 nm. While the third method was HPLC; where ENT was separated from ENT deg. using Zobrax C18column and methanol: water (30:70, v/v), pH 3 as a mobile phase. The three developed methods were validated according to ICH guidelines. Results Linearity range of ENT was 5.00–50.00 μg/mL for both D2and MCR. However, higher sensitivity was achieved using HPLC (1.00–50.00 μg/mL). Accuracy of ENT were 100.60%±0.547, 101.55%±1.2071 and 100.61%±1.207 for D2, MCR and HPLC methods, respectively, and precision was within 1.280. Conclusions The developed methods were successfully applied for the determination of ENT in Tecavir® tablets without interference from ENT deg. They showed no significant difference compared with the official method as well as they could be applied in the quality analysis of ENT with high selectivity, accuracy, and precision. Highlights ENT was quantified using two spectrophotometric (D2 and MCR) methods and an HPLC method in presence of ENT deg. The proposed methods were applied to analysis of ENT tablets with high selectivity, sensitivity, and accuracy.

Over the years, an increasing proportion of metastatic prostate cancer patients has been found to experience an initial bone flare phenomenon under both standard therapies (androgen deprivation therapy, chemotherapy, radiotherapy, abiraterone, enzalutamide) and novel agents (immunotherapy, bone-targeting radioisotopes). The underlying biological mechanisms of the flare phenomenon are still elusive and need further clarification, particularly in relation to different types of treatment and their treatment response assessment. Flare phenomenon is often underestimated and, in some cases, can negatively affect clinical outcome. In cases with suspected bone flare, the treatment should be continued for a minimum of 12 more weeks before further decisions about efficacy can be taken. Physicians and patients should be aware of this effect to avoid unwarranted anxiety and inadequate early discontinuation of treatment. This review aims at highlighting new evidence on flare phenomenon arising after the introduction of new drugs extending across the biochemical, radiographic and clinical spectrum of the disease.

Abstract In this study, essential (Ca, Cr, Cu, Fe, K, Mg, Na, P, Zn), and non-essential (Al, Ni, Pb) element contents of the drinking and baby water samples which are sold in the local market and tap water samples in Istanbul were examined. It was determined that elements of Cr, Cu, Fe, P, Zn, Al, and Ni were below detection limits in all water samples. Among the non-essential elements analyzed in water samples, Pb was the only detected element. At the same time, the percentages that meet the daily element requirements of infants were also calculated. As a result of the evaluations made, there is no significant difference in infant nutrition between baby waters and other drinking waters in terms of the element content.
