Vitamin D, a crucial hormone in the homeostasis and metabolism of calcium bone, has lately been found to produce effects on other physiological and pathological processes genomically and non-genomically, including the cardiovascular system. While lower baseline vitamin D levels have been correlated with atherogenic blood lipid profiles, 25(OH)D supplementation influences the levels of serum lipids in that it lowers the levels of total cholesterol, triglycerides, and LDL-cholesterol and increases the levels of HDL-cholesterol, all of which are known risk factors for cardiovascular disease. Vitamin D is also involved in the development of atherosclerosis at the site of the blood vessels. Deficiency of this vitamin has been found to increase adhesion molecules or endothelial activation and, at the same time, supplementation is linked to the lowering presence of adhesion surrogates. Vitamin D can also influence the vascular tone by increasing endothelial nitric oxide production, as seen in supplementation studies. Deficiency can lead, at the same time, to oxidative stress and an increase in inflammation as well as the expression of particular immune cells that play a pivotal role in the development of atherosclerosis in the intima of the blood vessels, i.e., monocytes and macrophages. Vitamin D is also involved in atherogenesis through inhibition of vascular smooth muscle cell proliferation. Furthermore, vitamin D deficiency is consistently associated with cardiovascular events, such as myocardial infarction, STEMI, NSTEMI, unstable angina, ischemic stroke, cardiovascular death, and increased mortality after acute stroke. Conversely, vitamin D supplementation does not seem to produce beneficial effects in cohorts with intermediate baseline vitamin D levels.

Introduction. Heart failure (HF) is characterized by neuroendocrine activation. The cardiac natriuretic hormones, including atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP), together with their related pro-peptides (proANP and proBNP) represent a group of peptide hormones produced by the heart. A normal NT-proBNP level has a high negative predictive value for heart failure. The use of NT-proBNP testing is helpful in diagnosing acute HF in the emergency care setting, allowing an early and optimal treatment. The purpose of this study is to assess the prognostic value of NT-proBNP in heart failure in children younger than 3 years old and to establish whether it correlates with the NYHA/Ross functional class and left ventricle systolic function.Methods. We enrolled 24 consecutive children with HF due to congenital heart diseases and dilated cardiomyopathy. The serum levels of NT-proBNP were measured, all patients underwent echocardiography and left ventricle ejection fraction was calculated.Results. The highest median value of NT-proBNP was recorded in patients with cyanotic heart diseases (248.0 fmol/mL), p = 0.610. NT-proBNP had a negative correlation with the ejection fraction of the left ventricle: Spearman's rank correlation coefficient was -0.165.Conclusions. NT-proBNP levels correlate with the severity of HF in infants and small children younger than 3 years old with heart failure due to congenital heart diseases and dilated cardiomyopathy.

When a cardiologist is asked to evaluate the cardiac toxic effects of chemotherapy, he/she can use several tools: ECG, echocardiography, coronary angiography, ventriculography, and cardiac MRI. Of all these, the fastest and easiest to use is the ECG, which can provide information on the occurrence of cardiac toxic effects and can show early signs of subclinical cardiac damage. These warning signs are the most desired to be recognized by the cardiologist, because the dose of chemotherapeutics can be adjusted so that the clinical side effects do not occur, or the therapy can be stopped in time, before irreversible side effects. This review addresses the problem of early detection of cardiotoxicity in adult and pediatric cancer treatment, by using simple ECG recordings.

Background and Aims. and Doppler echocardiography are the main methods for the non-invasive evaluation of ventricular function in children. Our study monitored the evaluation of systolic and diastolic function in pediatric patients, using classical echocardiographic parameters and pulsed tissue Doppler parameters, as well as the correlation between these.Methods. The study included 18 healthy children and 9 children diagnosed with congestive heart failure secondary to congenital heart malformations. The parameters of systolic and diastolic function were measured by 2D echocardiography, 2D guided M mode, color and pulsed Doppler, as well as by pulsed tissue Doppler at the level of the mitral and tricuspid annulus.Results. A relaxation alteration pattern or a pseudonormal pattern of E diastolic velocity compared to the A wave was found (E = A; E > A) in the group of subjects with heart failure. E wave deceleration time had significantly increased values in the case of patients with CHF, being correlated with diastolic dysfunction. Left ventricular flow propagation velocity Vp was decreased in patients with heart failure, the E/Vp ratio being maintained relatively constant in subjects with congestive heart failure and healthy subjects, most probably on account of the concomitant change in the E wave. Associations between the severity of systolic dysfunction and the diastolic dysfunction were found in pediatric patients diagnosed with congestive heart failure (Student test, p < 0.05).Conclusions. Tissue Doppler measurements proved to be useful for the evaluation of pediatric patients with altered ventricular geometry secondary to congenital heart disease, systolic-diastolic dysfunction and heart failure.

The diagnosis of cardiovascular malformations (CVM) is based on the echocardiographic evaluation. Multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI) are performant, necessary techniques for the pre- and postoperative assessment of complex malformations, especially of cyanogenic malformations, in which anomalies of the right side of the heart and of the pulmonary circulation are involved and where echocardiography has a limited role. The complementarity of echocardiography with MDCT and MRI for the acquisition of the details necessary for an accurate therapeutic decision and for avoiding invasive exploration, as well as the close relationship between the radiologist and the clinician are crucial and all the more necessary in complex malformations.

Hypertrophic Cardiomyopathy (HCM) is the most frequent hereditary cardiovascular disease and the leading cause of sudden cardiac death in young individuals. Advancements in CMR imaging have allowed for earlier identification and more accurate prognosis of HCM. Interventions aimed at slowing or stopping the disease’s natural course may be developed in the future. CMR has been validated as a technique with high sensitivity and specificity, very few contraindications, a low risk of side effects, and is overall a good tool to be employed in the management of HCM patients. The goal of this review is to evaluate the magnetic resonance features of HCM, starting with distinct phenotypic variants of the disease and progressing to differential diagnoses of athlete’s heart, hypertension, and infiltrative cardiomyopathies. HCM in children has its own section in this review, with possible risk factors that are distinct from those in adults; delayed enhancement in children may play a role in risk stratification in HCM. Finally, a number of teaching points for general cardiologists who recommend CMR for patients with HCM will be presented.

Urinary incontinence is one of the most common diseases, 25% of women between 18 and 80 years suffer from it. Urinary incontinence can be described as accidently loss of small amounts of urine. The solution involves a surgical procedure, such as sling procedures and bladder neck suspension procedures. The methods of surgical interventions have evolved due to a minimum period of hospitalization (sling, TVT), or performing laparoscopic surgery instead of the classical Burch surgery. Studies reviled that the most effective interventions are those which restore the urethra by retro pubic urethropexy, pubovaginal sling and synthetic mid-urethral slings. This type of surgery has currently the highest success rate (85-90% on 5 years after surgery), and the lowest relapse rate. In our study we obtained the same success rate for the TVT procedure.
