Abstract
Despite >1 in 5 children taking prescription drugs in the United States, off-label drug use is common. To increase the study of drugs in children, regulatory bodies have enacted legislation to incentivize and require pediatric drug studies. As a result of this legislation, novel trial approaches, and an increase in personnel with pediatric expertise, there have been numerous advancements in pediatric drug development. With this review, we aim to highlight developments in pediatric pharmacology over the past 6 years for the most common disease processes that may be treated pharmacologically by the pediatric primary care provider. Using information extracted from label changes between 2018 and 2023, the published literature, and Clinicaltrials.gov, we discuss advances across multiple therapeutic areas relevant to the pediatric primary care provider, including asthma, obesity and related disorders, mental health disorders, infections, and dermatologic conditions. We highlight instances in which new drugs have been developed on the basis of a deeper mechanistic understanding of illness and instances in which labels have been expanded in older drugs on the basis of newly available data. We then consider additional factors that affect pediatric drug use, including cost and nonpharmacologic therapies. Although there is work to be done, efforts focused on pediatric-specific drug development will increase the availability of evidence-based, labeled guidance for commonly prescribed drugs and improve outcomes through the safe and effective use of drugs in children.

Abstract
BACKGROUND Globally, high systolic blood pressure accounts for 10.8 million deaths annually. The deaths are disproportionately higher among black people. The reasons for this disparity are poorly understood, but could include a high burden of perinatal insults such as birth asphyxia. Therefore, we aimed to assess the incidence of elevated blood pressure and to explore associated factors among children born to women with obstructed labour. METHODS We followed up children born to women with obstructed labour aged 25 to 44 months at Mbale regional referral hospital that had participated in the sodium bicarbonate trial ( Trial registration number PACTR201805003364421) between October 2021 and April 2022. Our primary outcome was elevated blood pressure defined as blood pressure (either systolic or diastolic or both) ≥ the 90th percentile for age, height, and sex in the reference population based on the clinical practice guideline for screening and management of high blood pressure in children and adolescents. We used logistic regression to estimate odds ratios between selected exposures and elevated blood pressure. RESULTS The incidence of elevated blood pressure was (39/140, 27.9%: 95% (CI: 20.6-36.1)). Participants aged three years and above had twice the odds of elevated blood pressure as those aged less than three years (Adjusted odds ratio (AOR) 2.46: 95% CI (1.01-5.97). Female participants had 2.81 times the odds of elevated blood pressure as their male counterparts (AOR 2.81 95% CI (1.16-6.82). Participants with reduced estimated glomerular filtration rate had 2.85 times the odds of having elevated blood pressure as those with normal estimated glomerular filtration rate (AOR 2.85 95% CI (1.00-8.13). We found no association between arterial cord lactate, stunting, wealth index, exclusive breastfeeding, food diversity and elevated blood pressure. CONCLUSION Our findings show a high incidence of elevated blood pressure among children. We encourage routine checking for elevated blood pressure in the pediatric population particularly those with known risk factors.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) detection with B-mode and contrast-enhanced ultrasound (CUS) imaging often varies between subjects, especially in patients with background cirrhosis. Various factors contribute to this variability, including the tumor blood flow, tumor size, internal echoes, and its location in livers with diffuse fibro-cirrhotic changes. OBJECTIVE Towards improving lesion detection, this study evaluates a vasodilator, hydralazine, to enhance the visibility of HCC by reducing its blood flow relative to the surrounding liver tissue. METHODS HCC were analyzed for tumor visibility measured for B-mode, CUS, and hydralazine-augmented-contrast ultrasound (HyCUS) in an autochthonous HCC rat model. 21 tumors from 12 rats were studied. B-mode and CUS images were acquired before hydralazine injection. Rats received an intravenous hydralazine injection of 5 mg/kg, then images were acquired 20 min later. Four rats were used as controls. The difference in echo intensity of the lesion and the surrounding tissue was used to determine the visibility index (VI). RESULTS The visibility index for HCC was found to be significantly improved with the use of HyCUS imaging compared to traditional B-mode and CUS imaging. The visibility index for HCC was 16.5 ± 2.8 for HyCUS, compared to 5.3 ± 4.8 for B-mode and 4.1 ± 3.8 for CUS. The differences between HyCUS and the other imaging modalities were statistically significant, with p-values of 0.001 and 0.02, respectively. Additionally, when compared to control cases, HyCUS showed higher discrimination of HCC (VI = 6.4 ± 1.2) with a p-value of 0.003, while B-mode (VI = 6.7 ± 1.4, p = 0.5) and CUS (VI = 6.4 ± 1.2, p = 0.3) showed lower discrimination. CONCLUSION Vascular blood flow modulation by hydralazine enhances the visibility of HCC. HyCUS offers a potential problem-solving method for detecting HCC when B-mode and CUS are unsuccessful, especially with background fibro-cirrhotic liver disease. Future evaluation of the approach in humans will determine its translatability for clinical applications.

Abstract
Abstract Background The problem of cardiovascular diseases and lack of adequate information about the blood pressure profiles among children in South Africa has enormous consequences for public health and the general well-being of communities. Aim The aim of this study is to determine the blood pressure profiles and associated risk factors of primary school children in South Africa. Methods A cross sectional study was conducted among 876 children aged 9 to 14 years from 18 randomly selected schools in the Eastern Cape province of South Africa. Standardised blood pressure measuring instruments were used and an average of three readings was considered. Blood pressure status was classified according to the percentiles of systolic blood pressure (SBP). Results The overall prevalence of hypertension was 5.2% and pre-hypertension was 18.5% while normal blood pressure was 76.3%. The multilevel binary logistic regression’s crude and adjusted analysis revealed that increase in age was significantly associated with elevated BP in children ([crude OR = 1.17 [1.05 – 1.29] and [adjusted OR = 1.12 [1.01 – 1.25]). In addition, increase in BMI was significantly associated with elevated BP in children ([crude OR = 1.08 [1.04 – 1.12] and [adjusted OR = 1.06 [1.02 – 1.11]). There was no statistically significant association between elevated BP and gender for both the univariate and multivariate models. There was also no statistical significant risk for elevated BP associated with place of residence. Conclusions In this sampled population the established proportion of primary school children with elevated BP is of great concern. In addition, older children and those with high BMI (that is, overweight/obesity) were associated with elevated BP. Interventions towards promoting healthy lifestyles among school learners is a necessity if we are to prevent cardiovascular diseases.

Abstract
This study investigates the use of hydralazine to enhance ultrasound hyperthermia for the treatment of hepatocellular carcinoma (HCC) by minimizing flow-mediated heat loss from the tumor. Murine HCC tumors were treated with a continuous mode ultrasound with or without an intravenous administration of hydralazine (5 mg/kg). Tumor blood flow and blood vessels were evaluated by contrast-enhanced ultrasound (CEUS) imaging and histology, respectively. Hydralazine markedly enhanced ultrasound hyperthermia through the disruption of tumor blood flow in HCC. Ultrasound treatment with hydralazine significantly reduced peak enhancement (PE), perfusion index (PI), and area under the curve (AUC) of the CEUS time-intensity curves by 91.9 ± 0.9%, 95.7 ± 0.7%, and 96.6 ± 0.5%, compared to 71.4 ± 1.9%, 84.7 ± 1.1%, and 85.6 ± 0.7% respectively without hydralazine. Tumor temperature measurements showed that the cumulative thermal dose delivered by ultrasound treatment with hydralazine (170.8 ± 11.8 min) was significantly higher than that without hydralazine (137.7 ± 10.7 min). Histological assessment of the ultrasound-treated tumors showed that hydralazine injection formed larger hemorrhagic pools and increased tumor vessel dilation consistent with CEUS observations illustrating the augmentation of hyperthermic effects by hydralazine. In conclusion, we demonstrated that ultrasound hyperthermia can be enhanced significantly by hydralazine in murine HCC tumors by modulating tumor blood flow. Future studies demonstrating the safety of the combined use of ultrasound and hydralazine would enable the clinical translation of the proposed technique.

Abstract
INTRODUCTION Angiotensin converting enzyme inhibitors are commonly prescribed medications after the Norwood procedure. There are little data that can be used to determine if angiotensin converting enzyme inhibitors improve interstage outcomes in children with single ventricle defects. The objective of this study was to investigate the relationship between angiotensin converting enzyme inhibitors and interstage failure among infants born with hypoplastic left heart syndrome. METHODS We conducted a retrospective cohort study using data from the National Pediatric Cardiology Quality Improvement Collaborative database (collected between 2008 and 2015). We used logistic regression models to assess the exposure-outcome associations and propensity score matching to account for differences in baseline patient characteristics associated with use of angiotensin converting enzyme inhibitors. RESULTS A total of 1 487 neonates participated in the study. Thirty-nine percent of patients were prescribed angiotensin converting enzyme inhibitors after the Norwood procedure; 11% experienced interstage failure (death, heart transplantation, and not being a candidate for the second-stage surgery). Before propensity score matching, patients receiving angiotensin converting enzyme inhibitors were significantly more likely to experience interstage failure, compared to patients not on angiotensin converting enzyme inhibitors (OR = 1.44; 95% CI: 1.04, 1.99; P = 0.03). Although there was an increased odds of interstage failure among patients receiving angiotensin converting enzyme inhibitors compared to patients not receiving angiotensin converting enzyme inhibitors in the propensity score-matched cohort, this association was not significantly different (adjusted OR = 1.29; 95% CI: 0.88, 1.95; P = 0.18). CONCLUSION Angiotensin converting enzyme inhibitor therapy did not demonstrate a beneficial effect on interstage failure among infants with hypoplastic left heart syndrome, even when patient characteristics associated with the use of angiotensin converting enzyme inhibitors were considered.

Abstract
Background Whilst the burden of non-communicable diseases is increasing in developing countries, little data is available on blood pressure among Tanzanian children. This study aimed at determining the blood pressure profiles and risk factors associated with elevated blood pressure among primary school children in Dar es Salaam, Tanzania. Methods We conducted a cross sectional survey among 446 children aged 6–17 years from 9 randomly selected primary schools in Dar es Salaam. We measured blood pressure using a standardized digital blood pressure measuring machine (Omron Digital HEM-907, Tokyo, Japan). We used an average of the three blood pressure readings for analysis. Elevated blood pressure was defined as average systolic or diastolic blood pressure ≥ 90th percentile for age, gender and height. Results The proportion of children with elevated blood pressure was 15.2% (pre-hypertension 4.4% and hypertension 10.8%). No significant gender differences were observed in the prevalence of elevated BP. Increasing age and overweight/obese children were significantly associated with elevated BP (p = 0.0029 and p < 0.0001) respectively. Similar associations were observed for age and overweight/obesity with hypertension. (p = 0.0506 and p < 0.0001) respectively. In multivariate analysis, age above 10 years (adjusted RR = 3.63, 95% CI = 1.03–7.82) was significantly and independently associated with elevated BP in this population of school age children. Conclusions We observed a higher proportion of elevated BP in this population of school age children. Older age and overweight/obesity were associated with elevated BP. Assessment of BP and BMI should be incorporated in school health program in Tanzania to identify those at risk so that appropriate interventions can be instituted before development of associated complications.

Abstract
Background: Prior studies have not examined national trends and characteristics of unintentional non–health care facility (HCF) medication errors associated with cardiovascular drugs. Objective: To investigate non-HCF medication errors associated with cardiovascular drugs reported to poison control centers in the United States. Methods: A retrospective analysis of non-HCF medication errors associated with cardiovascular drugs from 2000 to 2012 was conducted using the National Poison Data System database. Results: There were 278 444 medication errors associated with cardiovascular drugs reported to US poison control centers during the study period, averaging 21 419 exposures annually. The overall rate of cardiovascular medication errors per 100 000 population increased 104.6% from 2000 to 2012 ( P < 0.001) and the highest rates were among older adults. Most cases (83.6%) did not require treatment at a HCF. Serious medical outcomes were reported in 4.0% of exposures. The cardiovascular drugs most commonly implicated in medication errors were β-blockers (28.2%), calcium antagonists (17.7%), and angiotensin-converting enzyme inhibitors (15.9%). Most of the 114 deaths were associated with cardiac glycosides (47.4%) or calcium antagonists (29.8%). Most medication errors involved taking or being given a medication twice (52.6%). Conclusions: This study describes characteristics and trends of non-HCF cardiovascular medication errors over a 13-year period in the United States. The number and rate of cardiovascular medication errors increased steadily from 2000 to 2012, with the highest error rates among older adults. Further research is needed to identify prevention strategies for these errors, with a particular focus on the older adult population.

Abstract
Background Childhood overweight and obesity are common causes of metabolic disorders that persist until adulthood. Objectives The purpose of this study was to determine the prevalence of high-normal arterial blood pressure (ABP) in children with excess body weight. Material and Methods A total of 1,093 schoolchildren aged 10 - 12 years (51% girls and 49% boys) participated in the study. The children’s weight, height, body fat percentage (BFP), waist and hip circumference, and ABP were measured. The waist-to-height ratio (WHtR) and body mass index (BMI) were calculated and compared to the normative reference values accepted by the International obesity task force (IOTF). Results Excess weight was identified in 20% of the participants, and obesity in 5%. A total of 35.5% of overweight children had above-normal ABP, which implied hypertension. In obese children, that proportion equaled 59.3%. BFP was 6.5% greater in children with hypertension than in those with normal BP. The children with hypertension also had a 7.6-cm larger waist circumference, a 7.6-cm larger hip circumference, and a greater WHtR (by 0.04). Conclusions Excess body weight was identified in 25% of children aged 10 - 12 years, significantly increasing their risk of developing hypertension.

Abstract
Hypertension in children is common, and the prevalence of primary hypertension is increasing with the obesity epidemic and changing dietary choices. Careful measurement of blood pressure is important to correctly diagnose hypertension, as many factors can lead to inaccurate blood pressure measurement. Hypertension is diagnosed based on comparison of age-, sex-, and height-based norms with the average systolic and diastolic blood pressures on three separate occasions. In the absence of hypertensive target organ damage (TOD), stage I hypertension is managed first by diet and exercise, with the addition of drug therapy if this fails. First-line treatment of stage I hypertension with TOD and stage II hypertension includes both lifestyle changes and medications. First-line agents include angiotensin-converting enzyme (ACE) inhibitors, thiazide diuretics, and calcium-channel blockers. Hypertensive emergency with end-organ effects requires immediate modest blood pressure reduction to alleviate symptoms. This is usually accomplished with IV medications. Long-term reduction in blood pressure to normal levels is accomplished gradually. Specific medication choice for outpatient hypertension management is determined by the underlying cause of hypertension and the comparative adverse effect profiles, along with practical considerations such as cost and frequency of administration. Antihypertensive medication is initiated at a starting dose and can be gradually increased to effect. If ineffective at the recommended maximum dose, an additional medication with a complementary mechanism of action can be added.

Abstract
Nearly one-third of the world's population has hypertension. The human and societal impact of hypertension is enormous. Primary hypertension accounts for 95 % of cases of hypertension in adults. The pathogenesis of primary hypertension is complex. The kidney and the sympathetic nervous system play important roles in the development and maintenance of hypertension. This review discusses their respective roles, the interaction between the two, implications of sympathetic overactivity in kidney disease and therapeutic interventions that have been developed on the basis of this knowledge, especially modulation of the sympathetic nervous system.

Abstract
Hypertension secondary to chronic kidney disease prevails in earlier childhood and obesity-related primary hypertension in adolescence. Both are associated with a high risk of renal and cardiovascular morbidity. In children with chronic kidney disease, uncontrolled hypertension may accelerate progression to end-stage renal disease before adulthood is reached and increase a child’s risk of cardiac death a thousand-fold. Obesity-related hypertension is a slow and silent killer, and though early markers of renal damage are recognized during childhood, end-stage renal disease is a risk in later life. Renal damage will be a formidable multiplier of cardiovascular risk for adults in whom obesity and hypertension tracks from childhood. Management options to prevent renal damage will vary for these different target groups. This review provides a summary of the available renoprotective strategies in order to aid physicians involved in the care of this challenging group of children.

Abstract
Although primary chronic hypertension (HTN) is increasingly common in adolescence, secondary forms of HTN are more common among children. Primary HTN is associated with being overweight and/or a positive family history of HTN. Carotid intima-media thickness, a known risk factor for atherosclerosis is frequent in both adults and children with HTN and other associated cardiovascular (CV) risk factors including obesity, dyslipidemia, diabetes and chronic kidney disease. Left ventricular (LV) hypertrophy is also a common finding in children and adolescents with newly diagnosed HTN. Children with certain medical conditions such as congenital heart disease and Kawasaki disease can develop premature atherosclerosis heart disease that may lead to coronary heart disease and heart failure. Life-style interventions are recommended for all children with HTN, with pharmacologic therapy added for symptomatic children based on the presence of co-morbidities. As an example, beta-blockers, angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blocker and/or calcium channel blockers would be best for children with CV risk factors such as diabetes or renal disease, whereas an ACE inhibitor in combination with a beta-blocker and diuretics including spironolactone are recommended for patients with heart failure and reduced LV ejection fraction. This report will summarize new developments in the management of pediatric HTN complicated with CV disease and heart failure and will address the appropriate antihypertensive therapy that could potentially reduce the future burden of adult CV disease.

Abstract
Over the last two decades, essential hypertension has become common in adolescents, yet remains under-diagnosed in absence of symptoms. Diagnosis is based on normative percentiles that factor in age, sex and height. Evaluation is more similar to adult essential hypertension than childhood secondary hypertension. Modifiable risk factors such as obesity, sodium consumption and low exercise should be addressed first. Many anti-hypertensive medications now have specific regulatory approval for children. Sports participation need not be limited in mild or well-controlled cases. Primary care physicians play an important role in reduction of cardiovascular mortality by early detection and referral when needed.

Abstract
The purpose of this meta-analysis was to examine the evidence for the effectiveness of exercise interventions on the resting blood pressure (systolic and diastolic) of obese children. A computerized search was made of seven databases using keywords. Effect sizes (ES) and 95% confidence intervals were calculated, and the heterogeneity of the studies was estimated using Cochran's Q-statistic applied to the effect size means. Nine randomized controlled trial (RCT) studies were selected for review as satisfying the inclusion criteria (n = 205 exercise, 205 control). The main cumulative evidence indicates that the exercise programmes with a frequency of three sessions weekly lasting longer than 60 min had a moderate effect on systolic blood pressure (ES = -0.46, I(2) = 27%), and programmes of under 12 weeks with more than three sessions weekly were beneficial in terms of reduction of diastolic blood pressure (ES = -0.35, I(2) = 78%).

Abstract
There has been an evolution in the understanding of the treatment of hypertension in children and adolescents over the past decade. This has been fueled in part by the increased attention paid to the clinical problem, given the increasing numbers of children and adolescents being diagnosed with this condition. There has also been a growing number of clinical trials performed and completed that demonstrate the blood pressure (BP)-lowering effects of antihypertensives and the side effect profiles of these medications, and that has led to FDA-labeling of many antihypertensive medications for use in children and adolescents. However, none of these trials has provided definitive data on the optimal first line agent for this patient population. Clinical experience and other approaches discussed in this review are still necessary to guide treatment of hypertension in the young. The quest for the optimal antihypertensive agent is just beginning, and it is going to take some extraordinary effort to reach that goal.

Abstract
Medical conditions diagnosed during adolescence may have long term impacts on the health of an individual. As a result, identifying cardiovascular risk factors earlier in life such as prehypertension (pre-HTN) and hypertension (HTN) can have significant benefits across an individual’s lifespan. Diagnosing elevated blood pressure (BP) during adolescence can be difficult, partially due to the natural variability that occurs during this period of life. Levels of BP that define adolescent prehypertension/hypertension are provided as well as an abridged review of BP variability across research groups. Strategies for BP management of adolescents are considered, with the primary focus on nonpharmacologic interventions.

Abstract
As a result of the Food and Drug Administration (FDA) Modernization Act and the Best Pharmaceuticals for Children Act, the number of medications with FDA-approved pediatric labeling has increased. To assess the success of these initiatives, we examined whether antihypertensive drugs used by children with hypertension in 2008 had FDA-approved pediatric labeling and indications. Using a nationwide commercial insurer database, 2915 children with primary (n=2607) and secondary (n=308) hypertension were identified. Drug user rate and days of supply were calculated from pharmacy claims. Drugs were categorized based on pediatric labeling and indication and whether they were recommended for pediatric use. Antihypertensive drugs were used by 889 (34%) children with primary hypertension and 200 children (65%) with secondary hypertension. User rates were 44.3% in hypertensive children younger than 6 years, 30.9% in those 6 years to older than 12 years, and 38.1% in those 12 years to older than 18 years. Seven percent of drugs were neither labeled for pediatric use nor considered recommended for use in children. In children younger than 6 years, 29% of drugs used were not indicated for use in that age group. Despite recent legislative initiatives, many drugs used by hypertensive children still lack pediatric labeling. Additional efforts are needed to close the gap between the availability of drugs that are labeled and indicated for pediatric use and actual drug usage in children.

Abstract
Primary hypertension in children is increasing in prevalence with many cases likely going undiagnosed. The prevalence is currently estimated at between 3%-5% in the United States and may be higher in certain ethnic groups. Primary hypertension, once felt to be rare in children, is now considered to be about five times more common than secondary hypertension. This review provides information to guide physicians through an organized approach to: 1) screening children and adolescents for hypertension during routine visits; 2) using normative percentile data for diagnosis and classification; 3) performing a clinical evaluation to identify the presence of co-morbidities; 4) initiating a plan of care including subsequent follow-up blood pressure measurements, therapeutic lifestyle changes and pharmacologic therapies.

Abstract
Cardiorenal syndrome (CRS) is a new term recently introduced to describe the acute or chronic comorbid state of the heart and kidney that has been long known and frequently managed in very sick individuals. The tight and delicate coordination of physiological functions among organ systems in the human body makes dysfunction in one to lead to malfunction of one or more other organ systems. CRS is a universal very common morbidity in the critically ill, with a high mortality rate that has received very little research attention in children. Simultaneous management of heart and renal failures in CRS is quite challenging; the therapeutic choice made for one organ must not jeopardize the other. This paper reviews the epidemiology, pathophysiology, clinical characteristics and management of acute and chronic CRS in children.

Abstract
There has been a steady increase in the prevalence of adolescent hypertension in recent years. In order to prevent target organ damages, it is important to determine the group of hypertensive adolescents. If repeatedly elevated blood pressure values are observed, with special emphasis on white coat hypertension, which is particularly frequent at this age, ambulatory blood pressure monitoring is highly recommended before pharmacological treatment is started. In addition, performing ambulatory blood pressure monitoring is recommended with target organ damage, resistance to therapy, and suspicion of secondary hypertension. The results of the widely available, simple-to-use device are easy to reproduce.

Abstract
Childhood hypertension has classically been recognized as a secondary disease. However, primary hypertension also occurs in children. The aim of this study was to compare clinical features of pediatric patients with elevated blood pressure, which were referred to an outpatient tertiary unit, and to detect variables associated with the identification of primary hypertension. The records of 220 patients with hypertension followed between 1996 and 2006 were analyzed. The variable of interest was primary hypertension. Logistic regression analysis was applied to identify clinical variables that were independently associated with primary hypertension. Of 220 patients, 33 (15%) had primary hypertension, and 187 (85%) exhibited secondary hypertension. No statistically significant differences were detected in gender, race, age at diagnosis, and systolic/diastolic blood pressure levels between both groups. After adjustment, four variables at baseline remained independently associated with primary hypertension: absence of signs/symptoms (OR 18.87, 95% CI 6.32-56.29), normal serum creatinine (OR 0.02, 95% CI 0.00-0.27), family history of hypertension (OR 3.03, 95% CI 1.04-8.79), and elevated body weight (OR 1.06, 95% CI 1.02-1.10). The absence of signs/symptoms, normal serum creatinine, family history of hypertension, and overweight/obesity at admission are clues to diagnose primary hypertension in childhood.

Abstract
Physical activity (PA) and diet directly influence obesity and metabolic syndrome (MS) as important determinants of body composition. Understanding how PA relates to MS in youth is of great importance, and could offer a common strategy for clinical and public health approaches to control this condition. The underlying disorder of MS is a condition of insulin resistance, and a strong relationship between PA level and insulin sensitivity is clearly ascertained. The type, duration, frequency and intensity of PA affect fuel metabolism, in particular carbohydrate and lipid oxidation. The possible modulation of metabolism because of increased fat oxidation by PA is the basis for both prevention and restoration of insulin resistance and MS in obese children. In daily clinical practice, diet followed by pharmacologic treatment are usually the approaches taken, whereas PA is often considered just a suggestion. Although diet and PA have different effects on body composition, with both contributing to fat loss, only PA increases muscle mass and thus has a direct effect on metabolic function, expressed by changes in cardiovascular risk factors. Therefore, it is important to remember their complementary but different targets in daily clinical practice, such as body weight control for diet and metabolic health for PA. In this review, we have summarized the literature on the relationship between PA and MS in pediatrics. Then, we have analyzed the possibility of using PA for MS treatment, as an alternative to drugs, by discussing the results of intervention studies, reasons for low compliance to PA, related benefits, adherence difficulties and costs. Finally, we have tried to suggest recommendations for a multiple-step PA strategy in children and adolescents at risk for MS, by considering PA as the 'key' player in treatment.

Abstract
The prevalence of adolescent hypertension is increasing. The national epidemiological study found 2.5% prevalence, while it is 4.5% according to the newest international survey. Repeated casual blood pressure measurements, but not ambulatory blood pressure monitoring is needed for the diagnosis of adolescent hypertension on the basis of the presently available European guideline. At the last decade growing evidence came into light for ambulatory blood pressure monitoring in adolescence. These data show better correlation with end-organ damages than casual measurements. In patients with hypertension diagnosed based on repeated casual blood pressure measurements, 24-hour monitoring showed normal blood pressure in 21-47%, so this is the rate of white coat hypertension. Masked hypertension can also be diagnosed with the help of this method, which has a prevalence of 7-11%. We can also get useful data for secondary forms of hypertension. Until the appearance of the new European guidelines, more frequent use of ambulatory blood pressure monitoring is affordable. The confirmation of the diagnosis based on elevated casual blood pressure data is important. Ambulatory blood pressure monitoring is suggested in cases suspicious for white coat or masked hypertension, in cases of target organ damages or therapy resistant hypertension. Before administration of pharmaceutical therapy in adolescence hypertension - according to author's opinion - ambulatory blood pressure monitoring is absolutely necessary.
