1. Assessment of serum endocan levels in patients with beta-thalassemia minor
SUMMARY OBJECTIVE: Beta-thalassemia minor is a blood disease caused by a hereditary decrease in beta-globin synthesis, frequently leading to hypochromic microcytic anemia. Formerly called endothelial cell-specific molecule 1, endocan is a proteoglycan released by vascular endothelial cells in many organs. Our aim was to investigate the relationship between

2. Meta-Analysis of Pulmonary Artery Denervation for Treatment of Pulmonary Hypertension
ABSTRACT Introduction: Pulmonary artery denervation (PADN) can reduce the sympathetic nervous system (SNS) activity, reduce pulmonary artery pressure (PAP), and improve the quality of life in patients with pulmonary hypertension (PH). We conducted a systematic meta-analysis of the effectiveness of PADN in the treatment of PH patients. Methods: This is a co

3. Linear and Nonlinear Heart Rate Variability Analysis in Gonadal Dysgenesis (Swyer Syndrome): A Case Report
Abstract Swyer syndrome is one of the disorders of sexual differentiation. Previous studies have demonstrated increased sympathetic activity with heart rate variability (HRV) analysis with decreasing estradiol levels. One patient presented a pure 46, XY gonadal dysgenesis with female phenotype. Cardiac autonomic modulation was assessed through HRV analysis w

4. Influence of Family History of Diabetes on Cardiac Autonomic Dysfunction of Adolescents
Abstract Background To evaluate cardiac autonomic modulation of adolescents with a family history of diabetic parents. Objective This study aims to evaluate the influence of a family history of diabetes on cardiac autonomic modulation. Methods This is an analytical and cross-sectional study on adolescents between 11 and 18 years of age, of both genders

5. Association between benign prostate enlargement-related storage and voiding symptoms and systolic blood pressure: a single-center cross-sectional study
ABSTRACT BACKGROUND: Lower urinary tract symptoms significantly worsen quality of life. The hypothesis that they might lead to serious systolic blood pressure alterations through inducing sympathetic nervous activity has not been studied so far. OBJECTIVES: To investigate the relationship between benign prostate enlargement-related storage and voiding sy

6. Respostas autonômicas de recém-nascidos prematuros ao posicionamento do corpo e ruídos ambientais na unidade de terapia intensiva neonatal
RESUMO Objetivo: Avaliar as respostas fisiológicas e do sistema nervoso autônomo de recém-nascidos prematuros ao posicionamento do corpo e ruídos ambientais na unidade de terapia intensiva neonatal. Métodos: Este foi um estudo quasi-experimental. O sistema nervoso autônomo de recém-nascidos foi avaliado com base na variabilidade da frequência card�

7. Acute Physical Stress Preconditions the Heart Against Ischemia/Reperfusion Injury Through Activation of Sympathetic Nervous System
Resumo Fundamento: O estresse é definido como um estado complicado de distúrbios da homeostase, hiperatividade do sistema nervoso simpático e das respostas do eixo hipotálamo-hipófise-adrenal. O pré-condicionamento cardíaco diminui os danos do miocárdio. Objetivo: Esse estudo avaliou os efeitos cardioprotetores do estresse físico agudo contra a le

8. Presence of age- and sex-related differences in heart rate variability despite the maintenance of a suitable level of accelerometer-based physical activity
There is currently a lack of information adjacent on the influence of sex and age in heart rate variability (HRV), adjusted according to accelerometer-based physical activity (PADL). We hypothesized that the effect of sex and age on the HRV should be reduced or absent in individuals with a suitable PADL level. We aim to evaluate the influence of sex and age

9. SEDENTARY LIFESTYLE IN ADOLESCENTS IS ASSOCIATED WITH IMPAIRMENT IN AUTONOMIC CARDIOVASCULAR MODULATION
RESUMO Introdução A prática regular de exercícios físicos ou o estilo de vida mais ativo são importantes na prevenção de doenças cardiovasculares, reduzindo não somente a mortalidade cardiovascular, mas também favorecendo a redução dos fatores de risco relacionados com essas doenças. Objetivo Avaliar a associação entre inatividade física

10. Sympatho-Vagal Imbalance is Associated with Sarcopenia in Male Patients with Heart Failure
Resumo Fundamento: Hiperatividade simpática de repouso e uma reativação parassimpática diminuída pós-exercício têm sido descritas em pacientes com insuficiência cardíaca (IC). No entanto, a associação dessas alterações autonômicas em pacientes com IC sarcopênicos ainda não são conhecidas. Objetivo: O objetivo deste estudo foi avaliar o im

11. ACE gene dosage determines additional autonomic dysfunction and increases renal angiotensin II levels in diabetic mice
OBJECTIVES: The present study aimed to investigate cardiovascular autonomic modulation and angiotensin II (Ang II) activity in diabetic mice that were genetically engineered to harbor two or three copies of the angiotensin-converting enzyme gene. METHODS: Diabetic and non-diabetic mice harboring 2 or 3 copies of the angiotensin-converting enzyme gene were

12. Resting spontaneous baroreflex sensitivity and cardiac autonomic control in anabolic androgenic steroid users
OBJECTIVES: Misuse of anabolic androgenic steroids in athletes is a strategy used to enhance strength and skeletal muscle hypertrophy. However, its abuse leads to an imbalance in muscle sympathetic nerve activity, increased vascular resistance, and increased blood pressure. However, the mechanisms underlying these alterations are still unknown. Therefore, w
