Hypertension is the most common finding in chronic kidney disease patients, with prevalence ranging from 60% to 90% depending on the stage and etiology of the disease. It is also a significant independent risk factor for cardiovascular disease, progression to end-stage kidney disease and mortality. According to the current guidelines, resistant hypertension is defined in the general population as uncontrolled blood pressure on three or more antihypertensive drugs in adequate doses or when patients are on four or more antihypertensive drug categories irrespective of the blood pressure control, providing that antihypertensive treatment included diuretics. The currently established definitions of resistant hypertension are not directly applicable to the end-stage kidney disease setting. The diagnosis of true resistant hypertension requires confirmation of adherence to therapy and confirmation of uncontrolled blood pressure values by ambulatory blood pressure measurement or home blood pressure measurement. In addition, the term “apparent treatment-resistant hypertension,” defined as an uncontrolled blood pressure on three or more antihypertensive medication classes, or use of four or more medications regardless of blood pressure level was introduced. In this comprehensive review we focused on the definitions of hypertension, and therapeutic targets in patients on renal replacement therapy, including the limitations and biases. We discussed the issue of pathophysiology and assessment of blood pressure in the dialyzed population, management of resistant hypertension as well as available data on prevalence of apparent treatment-resistant hypertension in end-stage kidney disease. To conclude, larger sample-size and even higher quality studies about drug adherence should be conducted in the population of patients with the end-stage kidney disease who are on dialysis. It also should be determined how and when blood pressure should be measured in the group of dialysis patients. Additionally, it should be stated what the target blood pressure values in this group of patients really are. The definition of resistant hypertension in this group should be revisited, and its relationship to both subclinical and clinical endpoints should be established.

The predictive value of heart rate (HR) measured using automated office blood pressure measurement (AOBPM) remains unknown.This study aimed to determine the impact of AOBPM HR on the cardiovascular events in hypertensive subjects with and without prior cardiovascular disease (CVD).Data of 9361 participants of the Systolic Blood Pressure Intervention Trial (median follow-up 3.26 years) were used to perform post-hoc analysis based on baseline AOBPM HR levels (50, 50-60, 60-70, 70-80 and80 b.p.m.). Clinical composite end-point (CE) was defined as myocardial infarction (MI), acute coronary syndrome other than MI, heart failure exacerbation, stroke or cardiovascular death. Cardiovascular-related and all-cause mortalities were also evaluated.A total of 1877 participants with and 7484 without CVD were included. Those with higher baseline HR were less frequently males and more often smokers, had higher BMI and eGFR, had lower baseline systolic blood pressure and higher diastolic blood pressure. No differences were observed in the CE frequency, its components and all-cause death between baseline HR groups. Elevated HR (70 b.p.m.) was associated with higher risk of CE, MI and cardiovascular death in multivariable Cox model. Moreover, the model determining the MI risk showed a J-shaped relationship with HR and a significant interaction term (P = 0.049) between HR and CVD history.High AOBPM HR is associated with a higher risk of cardiovascular events and mortality, whereas low HR may result in higher MI risk in patients who previously had CVD.

Objective: The objective of this paper is to present possible differences in spondylometric dimorphic characteristics of lumbar spine in the period of progressive development. Material and methods: The research material included 24,517 individuals of both sexes aged from 3 to 25. Individuals that showed abnormal structure of the motor system and individuals reporting pain in the joints of the spine were excluded. Spondylometric research was carried out using the Penny & Giles electrogoniometric measuring system. Significance tests concerning position measurements (Student's t-test, Welch's t-test) were used as well as biometric profiles formed on the basis of Mollison index for each characteristic in the studied period of ontogenesis. The progress of development of the examined spondylometric characteristics in both sex groups was calculated on the basis of expressing the size of the feature in successive age groups as a percentage of its final size. Using the linear and polynomial regression models, the developmental lines of the studied spondylometric parameters were obtained in males and females. Results: In the development process of the studied spondylometric parameters, dimorphic diversity can be observed essentially only in adolescence. In general, in the whole studied period of ontogenetic development, the greater range of lumbar spine mobility is found in females. Minor sexual dimorphism is also evident in the dynamics of development and in the stage of development of the majority of examined characteristics in individual age ranges in relation to the final values, for the benefit of the female sex.

Adequate control of blood pressure (BP) is essential to prevent complications in pregnant women with a history of eclampsia or pre-eclampsia. However, the importance of office (OBPM), home (HBPM), and ambulatory (ABPM) BP measurements for proper control and prognosis in high-risk pregnancy is unknown. The present study aimed to compare BP values obtained during these three different BP measurements in women with a history of eclampsia or pre-eclampsia. This study included 79 pregnant women with chronic hypertension and a documented history of eclampsia or pre-eclampsia in previous pregnancy/pregnancies. Every fifth week of the study, all participants underwent ABPM, HBPM and OBPM. BP values from the 10th, 25th, and 37th weeks of pregnancy were evaluated. Therapy was intended to meet the ABPM treatment goal of

IntroductionRepeated measurements of ankle-brachial index (ABI) using Doppler method were shown to be accurate during atrial fibrillation. Oscillometric devices are effective in ABI measurement, but their accuracy during atrial fibrillation is unknown. The purpose of the study was to investigate whether atrial fibrillation influences ABI obtained with the automatic oscillometric method.Material and methodsNinety-nine patients with atrial fibrillation (mean age: 66.6 +(SD = 11) years, M/F  63/36) who underwent electrical cardioversion were investigated (198 lower extremities). The ABI measurements using oscillometric and Doppler methods were performed on both lower extremities before and after procedure.ResultsThe ABI measured using the oscillometric method on both lower limbs did not change after cardioversion (1.21 (IQR: 1.13-1.27) vs. 1.22 (IQR: 1.14-1.26), p = 0.664, respectively). The ABI measured before and after cardioversion using Doppler and oscillometric methods showed a significant difference (1.14 (IQR: 1.07-1.22) vs. 1.21 (IQR 1.13-1.27), p < 0.001 and 1.18 (IQR: 1.09-1.13) vs. 1.22 (IQR: 1.14-1.26), p < 0.001 respectively). Both methods showed a weak correlation before (r = 0.35, p < 0.001) and no correlation after cardioversion (r = 0.12, p = 0.07). The Bland-Altman plot showed poor agreement between measurements performed with the Doppler and oscillometric methods in sinus rhythm and during atrial fibrillation.ConclusionsThe automated oscillometric method of ABI measurements should not replace the reference Doppler method in patients with atrial fibrillation. More research related to the oscillometric measurements is needed in subjects with peripheral artery disease and atrial fibrillation.

Background: The guidelines recommend intensive blood pressure control. Randomized trials have focused on the relevance of the systolic blood pressure (SBP) lowering, leaving the safety of the diastolic blood pressure (DBP) reduction unresolved. There are data available which show that low DBP should not stop clinicians from achieving SBP targets; however, registries and analyses of randomized trials present conflicting results. The purpose of the study was to apply machine learning (ML) algorithms to determine, whether DBP is an important risk factor to predict stroke, heart failure (HF), myocardial infarction (MI), and primary outcome in the SPRINT trial database. Methods: ML experiments were performed using decision tree, random forest, k-nearest neighbor, naive Bayesian, multi-layer perceptron, and logistic regression algorithms, including and excluding DBP as the risk factor in an unselected and selected (DBP < 70 mmHg) study population. Results: Including DBP as the risk factor did not change the performance of the machine learning models evaluated using accuracy, AUC, mean, and weighted F-measure, and was not required to make proper predictions of stroke, MI, HF, and primary outcome. Conclusions: Analyses of the SPRINT trial data using ML algorithms imply that DBP should not be treated as an independent risk factor when intensifying blood pressure control.

The aim of the study was the evaluation of the hormonal response of wheelchair rugby participants under the half-year training cycle. The study sample included 11 members of the Polish national wheelchair rugby team with spinal cord injury at the cervical level, ranging in age from 21 to 41 years, body weight (72.2 ± 11.53 kg), and body height (182.3 ± 6.11 cm). The disabled individuals with spinal cord injury subjected to the study constitute a homogeneous group in terms of age, body height, weight, and injury level. The study was carried out at the beginning and at the end of a 6-month training period. In the first and second examination, measurements of the peak oxygen uptake (peakVO2) and blood biochemical analysis were performed (Lactate dehydrogenase (LDH) activity and concentration of creatinine (Cr), total testosterone (TT), free testosterone (FT), and cortisol (C)). A significant change was observed in the concentration of C in the Wheelchair Rugby players’ blood between two research periods (p < 0.05 (ES:0.76)) and a correlation between the post-training change in FT/C concentration and the change in Cr concentration (r = −0.6014, p < 0.05). The 6-month training period did not result in overloads within the group of players. However, due to the significant loss of the capacity of the spinal cord injury (SCI) and the possibility of a life-threatening trend, the anabolic/catabolic status of the players should be monitored using blood biochemical indices.

Recent studies including the SPRINT trial have shown beneficial effects of intensive systolic blood pressure reduction over the standard approach. The awareness of the J-curve for diastolic blood pressure (DBP) causes some uncertainty regarding the net clinical effects of blood pressure reduction. The current analysis was performed to investigate effects of low on-treatment DBP on cardiovascular risk in the SPRINT population. The primary composite outcome was the occurrence of myocardial infarction, acute coronary syndrome not resulting in myocardial infarction, stroke, acute decompensated heart failure or death from cardiovascular causes. The prevalence of primary outcomes was significantly higher in subjects within low DBP in both standard (44–67 mmHg [10.8%] vs 67–73 mmHg [6.7%] vs 73–78 mmHg [5.1%] vs 78–83 mmHg [4.4%] vs 83–113 mmHg [4.3%], p

Objective The objective of the study was to assess the influence of forward head posture on the mechanical parameters and pressure pain threshold of superficial neck muscles in clinically nonsymptomatic individuals with sedentary jobs. Methods Twenty-five office workers with forward head posture and 25 office workers with normal head posture were matched for sex, age, body mass index, and the nature and duration of their work and were compared at a single point. The study participants were divided into study groups on the basis of photometric craniovertebral angle measurements. The upper trapezius, sternocleidomastoid, and splenius capitis mechanical properties were assessed in the sitting position. Primary outcome measures were muscle stiffness (N/m), muscle tone (Hz), and muscle elasticity. The secondary variable was perceived pain threshold. Results No significant differences between the groups were found for biomechanical properties and perceived pain threshold in the studied muscles. Conclusion Forward head posture has no impact on muscle stiffness, tone, and elasticity, nor does it increase the pressure sensitivity of superficial neck muscles in healthy, mildly symptomatic office workers. It is most likely that not incorrect posture of the cervical spine, but probably other factors combined with forward head posture, like comorbid acute and chronic cervical pain and musculoskeletal disorders or prolonged sitting, contribute to changes in active myofascial tone and tensegrity as well as increased pressure sensitivity of neck muscles.

Objective. The aim of this study was to determine the effect of general rehabilitation gymnastics on subjective and objective characteristics of locomotor system in older women with chronic LBP. To satisfy this goal, the outcomes in exercising women were compared with the results of nonexercising controls. Material and Methods. The study group included 21 women with chronic LBP (age 65-75 years), participating in a 3-year general rehabilitation program combining strength, stretching, endurance, balance, and stabilization exercises with Muscle Energy Techniques (MET). Control group included 20 women with chronic LBP, who neither undertook the gymnastics nor participated in other forms of physical activity. The list of outcome measures included pain severity (Numeric Rating Scale), limitations in the activities of daily living (Oswestry Disability Index and Roland-Morris Disability Questionnaire), mobility of all spinal segments (tensometric electrogoniometry), and bioelectrical activity of back muscles (kinesiologic electromyography). Results. Exercising women presented with lesser severity of current pain (by 62%, p Conclusions. These findings may point to beneficial effects of the combined exercise program.

Background Work-related neck disorders are among the most common dysfunctions in office workers. Understanding cervical myofascial mechanical characteristics that differentiate symptomatic from asymptomatic office workers is crucial for the understanding of musculoskeletal dysfunctions in workers with neck pain. Objective To assess the effect of moderate work-related neck disorders on head posture and stiffness and perceived pain threshold of the upper trapezius (UT) and sternocleidomastoid (SCM) muscles. Design Cross-sectional study. Setting Work environment. Participants Sixteen office workers with diagnosed moderate work-related neck disorders and 16 asymptomatic office workers matched for sex, age, body mass index, and the nature and duration of their work. Intervention Not applicable. Outcome The primary outcome measure consisted of measurements of head posture using craniovertebral angle and myotonometric muscle stiffness (Newtons per meter) of the UT and SCM muscles. The secondary output variable was the perceived pain threshold algometry of the studied muscles. Results Compared with controls, subjects with work-related neck pain had a significantly smaller craniovertebral angle (by 8.3%; Cohen d = 0.88, P = .02) and greater stiffness of the UT myofascial tissue (by 11.3%; Cohen d = 1.05, P = .006). No significant differences in perceived pain threshold of the myofascial tissue of the UT or SCM muscles were found between groups. Conclusion In this study female office workers with neck pain had increased anterior positioning of the head and stiffness of the UT muscle in the sitting posture, which was not associated with changes in the pressure pain threshold of this muscle.

Primary aldosteronism (PA) is a potentially curable form of secondary hypertension caused by excessive renin-independent aldosterone secretion, leading to increased target organ damage and cardiovascular morbidity and mortality. The diagnosis of PA requires measuring renin and aldosterone to calculate the aldosterone-to-renin ratio, followed by confirmatory tests to demonstrate renin-independent aldosterone secretion and/or PA subtype differentiation. Various antihypertensive drug classes interfere with the renin-angiotensin-aldosterone axis and hence evaluation for PA should ideally be performed off-drugs. This is, however, often precluded by the risks related to suboptimal control of blood pressure and serum potassium level in the evaluation period. In the present review, we summarized the evidence regarding the effect of various antihypertensive drug classes on biochemical testing for PA, and critically appraised the issue whether and which antihypertensive medications should be withdrawn or, conversely, might be continued in patients evaluated for PA. The least interfering drugs are calcium antagonists, alpha-blockers, hydralazine, and possibly moxonidine. If necessary, the testing may also be attempted during treatment with beta-blockers, angiotensin-converting enzyme inhibitors, and angiotensin receptor blockers but renin and aldosterone measurements must be interpreted in the context of known effects of these drugs on these parameters. Views are evolving on the feasibility of testing during treatment with mineralocorticoid receptor antagonists, as these drugs are now increasingly considered acceptable in specific patient subsets, particularly in those with severe hypokalemia and/or poor blood pressure control on alternative treatment.

BackgroundThe alpha-adrenolytics (AA) are not recommended in patients with EF reduced heart failure due to safety concerns. The aim of our study was to assess the safety of AA in patients hospitalized due to exacerbation of HF and the influence of these drugs on long-term endpoints.MethodsData collected by the National Health Fund was used. Patients hospitalized due to HF exacerbation were included. The primary outcome was all-cause mortality and the secondary was the first readmission due to HF or all-cause death occurring more than 30 days after discharge.ResultsOf 140 668 patients hospitalized in the year 2013 n=53317 were included and followed for a median of 56.3 months. AA patients had lower long-term mortality (52.8% vs. 54.9%, unadjusted P=0.038). The treatment with AA positively and affected long-term survival (adjHR 0.82, 95%CI 0.78-0.87, P

Introduction Optimal diastolic blood pressure (DBP) during antihypertensive treatment in patients without a history of cardiovascular disease (CVD) remains unknown. Objectives This post‑hoc analysis of the SPRINT (Systolic Blood Pressure Intervention Trial) data aimed to determine the optimal DBP evaluated using automated office blood pressure measurements (AOBPM) in hypertensive patients without a history of CVD. Patients and methods Data of 1470 patients with CVD and 7117 patients without CVD were used. Clinical composite endpoint (CE) was defined as the occurrence of myocardial infarction, acute coronary syndrome other than myocardial infarction, decompensation of heart failure, stroke, or cardiovascular death. Two different approaches based on the hazard ratio plot were used to identify the optimal DBP range. The first approach was to determine the 10 mm Hg-wide DBP range with the lowest risk for CE. In the second approach, it was assumed that the hazard ratio of CE at the boundary points of the optimal DBP range should be the same in patients with and without CVD. Results Two ranges of on-treatment DBP were proposed: 73.7 to 83.7 mm Hg (first approach) and 63.6 to 95.8 mm Hg (second approach). The risk for CE was increased by 3% and 20% at the boundary points of the range, respectively, depending on the method of DBP determination. Conclusions Due to the fact that the range determined by the second method was wide and substantially different from the one recommended by the European Society of Cardiology (70-79 mm Hg), we have concluded that a DBP range of 73.7 to 83.7 mm Hg, measured using AOBPM, should be considered optimal in patients without CVD.

Background Available evidence does not indicate whether resting heart rate (RHR) is an independent risk factor or just marker of elevated risk. None of the studies assessed impact of RHR on cardiovascular events, when RHR was measured using automated blood pressure measurements (AOBPM). Purpose To assess the relationship between RHR (measured using AOBPM) and cardiovascular events risk in subjects with hypertension. Methods The data of SPRINT trial obtained via NHLBI were used to perform the analysis. SPRINT trial assessed intensive lowering of systolic BP to a target RHR was measured using AOBPM device and calculated as an average of 3 measurements during the baseline visit of the study. Clinical composite endpoint (CE) of the study was defined as: myocardial infarction, acute coronary syndrome, decompensation of heart failure, stroke or cardiovascular death. The relationship between RHR and CE was assessed according to presence of cardiovascular disease (CVD) in past medical history. The statistical methods included t-test and chi-square test, Cox proportional risk models. The Cox models were adjusted for adjusted for age, sex, current smoking status and mean SBP during the trial. Restricted cubic splines were used to describe the relationship between RHR and hazard ratio. Results Data of 1877 participants with CVD and 7484 participants without CVD were analyzed. Subjects with cardiovascular disease were older (69.7±9.5 vs 67.5 years ± 9.4, p The multivariable Cox proportional hazard risk model revealed that RHR>80 bpm is an independent risk factor for CE in subjects without CVD (hazard ratio 1.37, 95% CI 1.01–1.85, p=0.043) while not in subjects with CVD (hazard ratio 0.99, 95% CI 0.57–1.71, p=0.98). Conclusion Elevated RHR (>80 bpm) measured using AOBPM is an independent risk factor for cardiovascular events in subjects with hypertension and without CVD. Figure 1. Heart ratio vs hazard ratio.

Introduction Polycythemia vera (PV) is a rare myeloproliferative disease associated with an increased prevalence of hypertension and increased risk of cardiovascular complications. However, the precise mechanisms leading to the elevation of blood pressure (BP) and secondary target organ damage remain poorly understood. Objectives The study aimed to evaluate BP profile, assess the activity of the sympathetic nervous system and the renin‑angiotensin system, and provide a comprehensive assessment of subclinical target organ damage in patients with PV. Patients and methods Twenty consecutive patients with newly diagnosed PV and 20 control subjects were included. The following were assessed: BP, levels of catecholamines, urinary and plasma O‑methylated catecholamine metabolites, concentrations of aldosterone and renin. We also assessed microneurography sympathetic nervous system activity (MSNA) and baroreflex control of heart rate as well as subclinical target organ damage. Results At similar levels of BP, BP variability was decreased in the PV group (mean [SD] 24‑hour systolic BP, 9 [3] vs 12 [3] mm Hg; P = 0.003). Patients with PV had lower norepinephrine excretion (mean [SD], 16.54 [6.32] vs 25.46 [12.88] μg/d; P = 0.03) as well as decreased MSNA as assessed by microneurography compared with controls (mean [SD] MSNA, 30.7 [8.7] bursts/min vs 38.7 [5.4] bursts/min; P = 0.007 and MSNA 51.8 [11] bursts/100 beats vs 61.1 [11.3] bursts/100 heart beats; P = 0.04). Baroreflex control of HR was unaltered in the PV group. Increased hemoglobin levels and red blood cell count correlated with decreased retinal capillary flow in patients with PV. Conclusions Patients with PV, characterized by high hemoglobin concentrations and hematocrit levels had lower sympathetic nervous activity and decreased BP variability as compared with controls. There was no relationship between hemoglobin plasma concentration, hematocrit level, and target organ damage.

The association between elevated resting heart rate (RHR) as a cardiovascular risk factor and lowering of systolic blood pressure (SBP) to currently recommended values remain unknown. Systolic Blood Pressure Intervention Trial (SPRINT) data obtained from the NHLBI were used to describe the relationship between RHR and SBP reduction to &lt, 120 mmHg compared to SBP reduction to &lt, 140 mmHg. The composite clinical endpoint (CE) was defined as myocardial infarction, acute coronary syndrome, decompensation of heart failure, stroke, or cardiovascular death. Increased RHR was associated with a higher CE risk compared with low RHR in both treatment arms. A more potent increase of risk for CE was observed in subjects who were allocated to the SBP &lt, 120 mmHg treatment goal. A similar effect of intensive and standard blood pressure (BP) reduction (p for interaction, 0.826) was observed in subjects with RHR in the 5th quintile (hazard ratio, 0.78, with 95% confidence interval (CI), 0.55–1.11) and in other quintiles of baseline RHR (hazard ratio, 0.75, with 95% CI, 0.62–0.90). Lower in-trial than baseline RHR was associated with reduced CE risk (hazard ratio, 0.80, with 95% CI, 0.66–0.98). We concluded that elevated RHR remains an essential risk factor independent of SBP reduction.

The aim of this study was to analyze the effects of aging on the viscoelastic properties of the upper trapezius (UT) and the sternocleidomastoid (SCM) muscle during transition from lying to sitting position.The study included 39 older (mean age 67±5.9years) and 36 younger (21.1±1.8years) women. Tone, stiffness and elasticity of the UT and the SCM were measured by means of myotonometry (MyotonPRO) in lying and then, in sitting position. The results were compared using two-way analysis of variance.Irrespective of the position, older women presented with significantly higher muscle tone, stiffness and elasticity than younger subjects (P0.05). In both groups, the transition from lying to sitting position resulted in a decrease (P0.05) in the tone and stiffness, but not the elasticity (P0.05) of the SCM, and stimulated an increase in the tone, stiffness and elasticity of the UT (P0.05). The degree of changes in both study groups was similar, except from the absolute value of the UT elasticity, significantly higher increase in older women than in younger subjects (P0.05).Age contributes to an increase in the stiffness and tone of the UT and the SCM, as well as to a decrease in the elasticity of these muscles in female subjects. In contrast, age exerts only a slight effect on the mechanical properties of both muscles during transition from lying to sitting position.

Background Regular Nordic Walking training could improve fitness and reduce tenderness in selected muscle groups in office workers. Objective An assessment of the effects of a 12-week Nordic Walking training program on the perceived pain threshold (PPT) and the flexibility of selected upper-body muscle groups in postmenopausal female office workers. Methods 39 office workers were selected at random for the treatment group (NWg, n = 20) and the control group (Cg, n = 19). The persons from the NW group completed a 12-week Nordic Walking training program (3 times a week/1 hour). PPTs measurements in selected muscles and functional tests evaluating upper-body flexibility (Back Scratch - BS) were carried out twice in every participant of the study: before and after the training program. Results A significant increase in PPT (kg/cm2) was observed in the following muscles in the NW group only: upper trapezius (from 1,32 kg/cm2 to 1,99 kg/cm2), mid trapezius (from 2,92 kg/cm2 to 3,30 kg/cm2), latissimus dorsi (from 1,66 kg/cm2 to 2,21 kg/cm2) and infraspinatus (from 1,63 kg/cm2 to 2,93 kg/cm2). Moreover, a significant improvement in the BS test was noted in the NW group compared with the control group (from -1,16±5,7 cm to 2,18±5,1 cm in the NW group vs from -2,52±6,1 to -2,92±6,2 in the control group). Conclusions A 12-week Nordic Walking training routine improves shoulder mobility and reduces tenderness in the following muscles: trapezius pars descendens and middle trapezius, infraspinatus and latissimus dorsi, in female office workers.

The aim of this work was to analyze postural stability of girls having progressive form of idiopathic scoliosis and undergoing specific period of the adolescent growth spurt. Twenty-seven girls, aged 13.4 ± 1.2 years, presenting structural idiopathic scoliosis, thoracic or thoracolumbar pattern, radiological Cobb angle 41.7 ± 17.4° (study group) and 37 healthy girls (control group) were included. The groups were sex, age, height, weight, and BMI matched. Postural stability examination was performed using two stabilometric platforms with visual control (eyes open) at three stages: (1) both legs’ stance, (2) left leg stance, and (3) right leg stance. The Center of Pressure (COP) sway path length, the area and the displacement amplitude were compared. For the double stance, no difference in postural stability parameters between the groups was found. However, for the right leg stance, the total sway path length was longer (p=0.04) and the mean amplitude of the lateral COP displacement was increased (p=0.03) in the scoliotic group. In conclusion, for double stance, the adolescent girls with progressive form of idiopathic scoliosis revealed fair postural stability compared to control group. An impaired postural control was observed during right leg stance.

Background/Introduction Automated office blood pressure measurements (AOBPM) is recommended for the diagnosis of arterial hypertension. Nevertheless, use of automated office blood pressure in monitoring of treated patients with hypertension is limited by the discrepancies between AOBPM, auscultatory and research grade measurements of blood pressure. The treatment targets using AOBPM are not well-determined. Purpose This post-hoc analysis is aimed to establish the optimal range for on-treatment diastolic blood pressure (DBP) measured with AOBPM in hypertensive patients without cardiovascular disease but at high risk, who achieved systolic blood pressure treatment goal (SBP). Methods Data of 3715 subjects without prior cardiovascular disease treated to achieve SBP goal On-treatment blood pressure was computed as mean of AOBPM readings in a period from 6th month until to end of the study, which was considered as with a stable blood pressure. Optimal on-treatment DBP range was established on the basis of hazard ratio plot for clinical endpoint after adjustment for age, sex, SBP, smoking habits and history of chronic kidney disease. The target DBP range was set to be 10 mm Hg wide, what is line with current ESC/ESH guidelines. To evaluate nonlinear relationship between continuous variables and outcome cubic spline methods were used. Results Data of 3715 (38.3% female and 61.7% male) subjects aged 67.3±9.2 mm Hg were analysed. Mean on-treatment SBP and DBP were 120.8±8.5 mm Hg and 68.2±8.1 mm Hg, respectively. Lowest hazard risk of primary endpoint was found in on-treatment DBP range 62.8–72.8 mm Hg with a minimum at 67.8 mm Hg (Figure 1). Hazard risk increased linearly toward lower and higher values than selected optimal DBP range. Figure 1 Conclusion(s) In treated hypertensives at high cardiovascular risk, but without prior cardiovascular disease who achieved SBP treatment goal, on treatment DBP 62.8–72.8 mm Hg range should be considered when treatment is monitored using AOBPM.

(1) Background: Idiopathic scoliosis is a deformity of the growing spine. It affects 2&ndash, 3% of adolescents, yet its cause is still unknown. At the early stage of idiopathic scoliosis (IS), the signs are not very noticeable. That is why the primarily school-based screening for scoliosis is so important. (2) Methods: This was a cross-sectional analysis of 6850 respondents. Participants were elementary school students in the metropolitan area of Poland. The suspicion of IS was based on detection of three-dimensional deformity of the spine using scoliometer. (3) Results: Respondents were divided into two groups: Angle of trunk rotation (ATR) = 0&ndash, 3&ordm, and ATR &gt, Presented research using a referral criterion of 5&ordm, ATR showed that in the group of participants who had ATR &gt, the largest percentage of 5 degree values was recorded at the second and third measurement level of the spine (30.5%, 31.1%, respectively). Analyzing the differences between the two groups of girls (ATR = 0&ndash, ATR &gt, ), statistically significant differences were recorded between 9 and 11 years of age (p = 0.0388). Girls with ATR &gt, at all measuring levels are significantly slimmer than girls with ATR 0&ndash, (4) Conclusions: Age, sex, and risk of developing angle of trunk rotation are very closely associated. The main thoracic (level 2) and thoraco-lumbar (level 3) level of measuring of the spine appears to be the most differentiating in the diagnosis of scoliosis. Girls with a lower degree of trunk deformity (4&ndash, 6&ordm, trunk rotation), which can present mild scoliosis and those with a higher degree (7&ordm, trunk rotation) have lower body mass than girls within the norm.
