Association between hospital anxiety depression scale and autonomic recovery following exercise

The hospital anxiety depression scale (HADS) is a benchmark used to investigate possible and probable cases of psychosomatic illness. Its affiliation with autonomic recovery after exercise is unclear and, as a technique applied to evaluate cardiovascular risk. We assessed a possible link between HADS and autonomic recovery after exercise. We studied healthy subjects split into two groups: Low HADS (n = 20) and High HADS (n = 21). Subjects consented to moderate aerobic exercise on a treadmill at 60% to 65% of the maximum heart rate (HR) for 30 min. We studied HR variability (HRV) before and during 30 min after exercise. Subjects with higher HADS values presented delayed recovery of HR and root-mean square of differences between adjacent normal RR intervals (RMSSD) after submaximal exercise. RMSSD during recovery from exercise had a significant association with HADS. In summary, subjects with higher HADS presented slower vagal recovery following exercise

Bitter orange (Citrus aurantium L.) intake before submaximal aerobic exercise is safe for cardiovascular and autonomic systems in healthy males: A randomized trial

Background: There are still no studies of the cardiovascular safety of the isolated use of Citrus aurantium in aerobic submaximal exercise. Objective: To evaluate the effect of C. aurantium supplementation on the recovery of cardiorespiratory and autonomic parameters following a session of submaximal aerobic exercise. Methods: Twelve healthy male adults achieved a crossover, randomized, double-blind, and placebo-controlled trial. C. aurantium (600 mg, p-synephrine at 30% amount [180 mg]) or placebo (600 mg of starch) were ingested 90 min before evaluation in randomized days. We evaluated systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse pressure (PP), mean arterial pressure (MAP), heart rate (HR) and, HR variability indexes at Rest and during 60 min of recovery from exercise. Results: Citrus aurantium ingestion accelerated the reduction in SBP after exercise, anticipated the return of vagal modulation of the heart after exercise via the HF (ms2), pNN50 (%), and 2 UV% indices. Moreover, rushed the output of sympathetic modulation after exercise via the 0V% index. No unfavorable cardiovascular effects were achieved for HR, DBP, PP, and MAP parameters. Conclusions: Citrus aurantium was shown to be safe for the cardiovascular and autonomic systems alongside submaximal aerobic exercise in healthy males

Prevalence of Asthma symptoms and risk factors in adolescents

Introdução: A asma é a doença crônica das vias aéreas que vem apresentando um aumento na sua prevalência entre os adolescentes nas últimas décadas. Os fatores relacionados com o seu desencadeamento são inúmeros, passando por fatores ambientais, genéticos, alimentares dentre outros. Objetivo: Analisar a prevalência dos sintomas da asma e possíveis fatores de risco associados em adolescentes. Método: Trata-se de um estudo transversal, descritivo e quantitativo realizado em 104 adolescentes de 13 e 14 anos, de ambos os sexos, de quatro instituições de ensino: três privadas e uma pública. Os participantes responderam a dois questionários: um sobre os fatores de risco para doenças alérgicas e o outro sobre os sintomas da asma (ISAAC módulo asma). Resultados: Responderam ao questionário 104 adolescentes: 54,8% meninas e 45,2% meninos. Os voluntários do sexo masculino apresentaram mais asma ativa (64,%) que as voluntárias (20%) (p = 0,01) e também tiveram mais asma diagnosticada (34,4%) do que as voluntárias (6,1%) (p = 0,04), além de mais chiado no peito após exercício (34,4%; 12,1%) (p = 0,03). Com relação à associação entre os sintomas e os fatores de riscos observou-se uma relação estatisticamente significante entre presença de sibilos e hospitalizações para as meninas de escolas públicas (p=0,05). Conclusão: Houve maior frequência de adolescentes do sexo masculino com asma ativa, asma diagnostica e sibilos após exercício físico. Por outro lado, as meninas da escola pública apresentaram um maior risco de hospitalização na presença de sibilos. Os demais fatores de riscos não apresentaram associações estatisticamente significantes com os sintomas da asma.Introduction: Asthma is a chronic disease of the airways, which is increasing its prevalence among teenagers recently. The trigger-related factors are numerous, including environmental factors, genetic, food among others. Objective: Investigate the prevalence of asthma symptoms and possible risk factors in adolescents. Methods: This is a cross-sectional, descriptive and quantitative study conducted in 104 adolescents aged between 13 to 14 years old of both sexes from four educational institutions: three private and one public. Participants answered two questionnaires: one on risk factors for allergic diseases (EISL) and the other on asthma symptoms (ISAAC asthma module). Results: 104 adolescents answered the questionnaire: 54.8% girls and 45.2% boys. Male subjects had the most active asthma (64%) than female (20%) (p = 0.01) and also had more physician-diagnosed asthma (34.4%) than girls (6.1%) (p = 0.04), more wheezing after exercise (34.4%; 12.1%) (p = 0.03). Regarding the association between the symptoms and the risk factors we observed a statistically significant relationship between the presence of wheezing and hospitalization for public schools girls (p = 0.05). Conclusion: There is a higher prevalence of asthma symptoms in males than in females unlike other studies was observed

Association between oral variables and heart rate variability

Abstract The heart rate variability is a useful method to assess cardiac autonomic modulation in patients undergoing dental procedures, because knowledge of physiological conditions provides greater security to the professional as well as the possibility of a better plan treatment to patient benefit. The aim of our study was to describe the association between cardiac autonomic control and dental variables. We consulted the databases Medline, SciELO, Lilacs and Cochrane, using the terms “autonomic”, “dentistry”, “heart rate variability”, “cardiovascular physiology.” The selected studies indicated a strong relationship between dental variables and HRV. There was an association between malocclusion, TMD, dental procedures cirugia and low HRV. Thus, they become more studies that relate to HRV in dental science, especially in clinical practice

Changes in heart period during endodontic treatment

Background: Tooh extraction was demonstrated to increase sympathetic modulation of the heart, however, it is not understood the effects of endodontic treatment on cardiac autonomic regulation. We evaluated heart rate variability (HRV) during endodontic treatment. Method: 50 male and female patients aged between 18 and 40 years old and diagnosed with irreversible pulpitis or pulp necrosis of the lower molars with indication of gender endodontic treatment were analyzed. HRV was analyzed in the time (SDNN, RMSSD, pNN50) and frequency (LF, HF and LF/HF ratio) domains recorded in the first session of root canal treatment. The indices were analyzed in the following periods: T1) ten minutes before the endodontic treatment, T2) ten minutes after the administration of anesthesia before endodontic treatment, T3) during the entire period of endodontic treatment and T4) thirty minutes after the end of the endodontic treatment. Results: The SDNN, RMSSD and pNN50 indices increased at T2 compared to T1, the pNN50 and RMSSD indices increased at T3 and T4 compared to T2. The LF in normalized units increased at T4 compared to T2 and in absolute units it was increased at T4 compared to T1. The HF in normalized units was reduced at T4 compared to T2 and in absolute units was reduced at T1, T3 and T4 compared to T2. The LF/HF ratio was higher at T4 compared to T2. Conclusion: The global modulation of heart increases after local anesthesia and vagal tone reduce during surgery procedures and after the surgical procedures
