Negligible Effects of Nutraceuticals from Beetroot Extract on Cardiovascular and Autonomic Recovery Response following Submaximal Aerobic Exercise in Physically Active Healthy Males: A Randomized Trial.

BACKGROUND: There is little evidence that nutraceuticals from beetroot extract are beneficial with regards to recovery of the cardiovascular parameters and the autonomic nervous system (ANS) after submaximal aerobic exercise, though this formulation is employed widely for this purpose. OBJECTIVE: To study the effects of beetroot extract supplementation on the recovery of cardiorespiratory and autonomic parameters after a session of submaximal aerobic exercise. METHODS: Sixteen healthy male adults commenced a cross-over, randomized, double-blind and placebo-controlled trial. Beetroot extract (600 mg) or placebo (600 mg) were ingested 120 min prior to evaluation on randomized days. We assessed systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse pressure (PP), mean arterial pressure (MAP), heart rate (HR) and HR variability (HRV) indexes at Rest and during 60 min of recovery from submaximal aerobic exercise. RESULTS: Beetroot extract ingestion slightly accelerated HR, SBP, DBP and MAP reduction following exercise associated to the placebo protocol (vs. rest). Yet no group effect (p = 0.99) was identified between the beetroot and placebo protocols on HR mean, in addition to interaction (group vs. time) (p = 0.60). No group effect was attained between the SBP (p = 0.90), DBP (p = 0.88), MAP (p = 0.73) and PP (p = 0.99) protocols and no significant differences (group vs. time) were observed between the values of SBP (p = 0.75), DBP (p = 0.79), MAP (p = 0.93) and PP (p = 0.63) between placebo and beetroot protocols. Similarly, the reoccurrence of cardiac vagal modulation after exercise via the HF (ms2) was enhanced, but not with regards to the RMSSD index. No group effect (p = 0.99) was identified for the HF (p = 0.90) and RMSSD (p = 0.67) indices. Likewise, we observed no significant differences (group vs. time) amongst the values of HF (p = 0.69) and RMSSD (p = 0.95) between the placebo and beetroot protocols. CONCLUSION: Whilst beetroot extract might assist the recovery of the cardiovascular and autonomic systems following submaximal aerobic exercise in healthy males, these results seem insignificant owing to minor differences between interventions and are weak clinically.

Nitrate-rich beet juice intake on cardiovascular performance in response to exercise in postmenopausal women with arterial hypertension: study protocol for a randomized controlled trial.

BACKGROUND: There is no evidence of the use of beetroot juice with a previously recommended dose of nitrate (NO3) (> 300 mg) on the cardiovascular performance during and recovery following exercise in postmenopausal women with systemic arterial hypertension (SAH). METHODS: We will investigate the effects of beetroot juice rich in NO3 acutely (800 mg) and during a week with daily doses (400 mg) on blood pressure, heart rate (HR), cardiac autonomic control, endothelial function, inflammatory, hormonal, and stress biomarkers oxidative stress and enzymes involved in nitric oxide synthesis and mitochondrial regulation, under resting conditions, as well as mediated by submaximal aerobic exercise sessions. Through a randomized, crossover, triple-blind, placebo-controlled clinical trial, 25 physically inactive women with SAH will undergo an acute and 1-week trial, each with two intervention protocols: (1) placebo and (2) beetroot, in which will ingest beet juice with or without NO3 in its composition with a 7-day washout interval. On collection days, exercise will be performed on a treadmill for 40 min at a speed corresponding to 65-70% of VO2peak. The collection of variables (cardiovascular, autonomic, and blood samples for molecular analyses) of the study will take place at rest (135 min after ingestion of the intervention), during exercise (40 min), and in the effort recovery stage (during 60 min) based on previously validated protocols. The collections were arranged so that the measurement of one variable does not interfere with the other and that they have adequate intervals between them. DISCUSSION: The results of this research may help in the real understanding of the nutritional compounds capable of generating safety to the cardiovascular system during physical exercise, especially for women who are aging and who have cardiovascular limitations (e.g., arterial hypertension) to perform physical exercise. Therefore, our results will be able to help specific nutritional recommendations to optimize cardiovascular health. TRIAL REGISTRATION: ClinicalTrials.gov NCT05384340. Registered on May 20, 2022.

Use of radiofrequency in the treatment of acne: a systematic review / Uso de la radiofrecuencia en el tratamiento del acné: una revisión sistemática / Uso da radiofrequência no tratamento da acne: uma revisão sistemática

ABSTRACT Acne, of great prevalence and impact, presents many forms that can be treated by hygiene, topical medications, and manual alternative interventions such as skin cleansing and electrotherapy. The use of radiofrequency in the treatment of acne aims to increase the temperature in the cutaneous tissue, causing several metabolic and structural reactions, such as stimulating neocollagenesis. This study aimed to investigate the use of high-frequency current as an adjunctive treatment for acne. This is a non-systematic review of indexed databases (MEDLINE, SciELO, LILACS). A total of 18 studies were included in this review and most of them related different treatment for acne associated with radiofrequency. Radiofrequency presents few complications and good results, besides having as an additional advantage the possibility of the patient returning to the routine immediately after application.

Can music influence cardiac autonomic system? A systematic review and narrative synthesis to evaluate its impact on heart rate variability.

BACKGROUND: and purpose: The impact of music on the human body extends beyond an emotional response. Music can bring benefits to the cardiovascular system by influencing heart rate variability (HRV), which is a well-accepted method to analyze the oscillations of the intervals between successive heartbeats and investigate the cardiovascular autonomic nervous system (ANS). This study is a systematic review to examine the effect of musical interventions on HRV. METHODS: We conducted a systematic search in PubMed, Scopus, Web of Science, and Cochrane and identified additional studies with hand searching of reference lists of relevant references. RESULTS: 29 original articles (24 pre-post intervention studies and five randomized controlled trials) with a total of 1368 subjects were available and eligible to be included in the systematic review. Within the whole, only three studies reveal no significant impact of music on HRV, which might be due to using a small sample size and a concise duration of music administration. Interestingly, the rest of the studies have suggested a positive impact of music on HRV with a 0.05 level of significance. CONCLUSION: This systematic review confirms music as a stimulus acting to the cardiac ANS that increases parasympathetic activity and HRV. The effects are, however, associated with a high risk of bias. Therefore, further studies are necessary to compare the impact of individualized music therapy to passive listening and preferred soundtracks.

Effect of the Use of Different Acoustic Stimuli on Cortical Auditory Evoked Potentials and Autonomic Cardiac Modulation.

PURPOSE: The aim of this study was to analyze the relationship between Cortical Auditory Evoked Potentials (CAEPs) measurements and autonomic cardiac modulation in relation to different acoustic stimuli and to verify which of these stimuli have more influence on the autonomic nervous system. METHODS: Sixty healthy women, aged between 18 and 25 years, participated in this study. Prior to the CAEP examination, blood pressure and resting heart rate were measured using a stethoscope, sphygmomanometer, and the Polar RS800CX cardiofrequency measures. After the collection of these measures, the CAEP test was started simultaneously with the HRV collection. RESULTS: All the HRV indices presented correlations with the components of the CAEPs. During the acoustic stimulation, a predominance of the modulation of the autonomic parasympathetic nervous system was observed. The harmonic and disharmonic stimuli were the ones that presented the most correlations between the measures analyzed in this study. CONCLUSIONS: There was an association between CAEP and cardiac autonomic modulation in relation to different acoustic stimuli. Among the acoustic stimuli used in this study, the ones that most influenced the autonomic cardiac modulation were harmonic and disharmonic stimuli, which are acoustically more complex stimuli.

Symbolic Analysis of Heart Rate Variability During Exposure to Musical Auditory Stimulation.

BACKGROUND: In recent years, the application of nonlinear methods for analysis of heart rate variability (HRV) has increased. However, studies on the influence of music on cardiac autonomic modulation in those circumstances are rare. OBJECTIVE: The research team aimed to evaluate the acute effects on HRV of selected auditory stimulation by 2 musical styles, measuring the results using nonlinear methods of analysis: Shannon entropy, symbolic analysis, and correlation-dimension analysis. DESIGN: Prospective control study in which the volunteers were exposed to music and variables were compared between control (no auditory stimulation) and during exposure to music. SETTING: All procedures were performed in a sound-proofed room at the Faculty of Science and Technology at São Paulo State University (UNESP), São Paulo, Brazil. PARTICIPANTS: Participants were 22 healthy female students, aged between 18 and 30 y. INTERVENTION: Prior to the actual intervention, the participants remained at rest for 20 min, and then they were exposed to one of the selected types of music, either classical baroque (64-84 dB) or heavy-metal (75-84 dB). Each musical session lasted a total of 5 min and 15 s. At a point occurring up to 1 wk after that day, the participants listened to the second type of music. The 2 types of music were delivered in a random sequence that depended on the group to which the participant was assigned. OUTCOME MEASURES: The study analyzed the following HRV indices through Shannon entropy; symbolic analysis-0V%, 1V%, 2LV%, and 2ULV%; and correlation-dimension analysis. RESULTS: During exposure to auditory stimulation by heavy-metal or classical baroque music, the study established no statistically significant variations regarding the indices for the Shannon entropy; the symbolic analysis-0V%, 1V%, and 2ULV%; and the correlation-dimension analysis. However, during heavy-metal music, the 2LV% index in the symbolic analysis was reduced compared with the controls. CONCLUSIONS: Auditory stimulation with the heavy-metal music reduced the parasympathetic modulation of HRV, whereas no significant changes occurred in cardiac autonomic modulation during exposure to the classical music.

Access to health services by lesbian, gay, bisexual, and transgender persons: systematic literature review.

BACKGROUND: The relationship between users and health services is considered essential to strengthen the quality of care. However, the Lesbian, Gay, Bisexual, and Transgender population suffer from prejudice and discrimination in access and use of these services. This study aimed to identify the difficulties associated with homosexuality in access and utilization of health services. METHOD: A systematic review conducted using PubMed, Cochrane, SciELO, and LILACS, considering the period from 2004 to 2014. The studies were evaluated according to predefined inclusion and exclusion criterias. Were included manuscripts written in English or Portuguese, articles examining the Lesbian, Gay, Bisexual, and Transgender population's access to health services and original articles with full text available online. RESULTS: The electronic databases search resulted in 667 studies, of which 14 met all inclusion criteria. Quantitative articles were predominant, showing the country of United States of America to be the largest producer of research on the topic. The studies reveal that the homosexual population have difficulties of access to health services as a result of heteronormative attitudes imposed by health professionals. The discriminatory attendance implies in human rights violations in access to health services. CONCLUSIONS: The non-heterosexual orientation was a determinant factor in the difficulties of accessing health care. A lot must still be achieved to ensure access to health services for sexual minorities, through the adoption of holistic and welcoming attitudes. The results of this study highlight the need for larger discussions about the theme, through new research and debates, with the aim of enhancing professionals and services for the health care of Lesbian, Gay, Bisexual, and Transgender Persons.

Globally chaotic analysis of Heart Rate Variability during acute auditory stimulus by heavy metal music / Medidas globalmente caóticas de variabilidade de frequência cardíaca durante estímulo auditivo agudo por música heavy metal

OBJECTIVE: Auditory stimulation with relaxing style music can improve cardiac autonomic regulation in subjects treated with a cardio-toxic medication. We assess the acute effect of heavy metal music on cardiac autonomic regulation, through novel high spectral chaotic global analysis techniques: (a) high spectral detrended fluctuation, (b) high spectral entropy (c) spectral multi-taper method. METHOD: We investigated young adult women between 18 and 30 years old exposed to heavy metal (75-84 dB) music for 20 min. Normality tests were applied: (i) Anderson-Darling, (ii) Ryan-Joiner (similar to Shapiro-Wilk); (iii) Lilliefors for low number of subjects. They all indicated a non-normal data distribution. Consequently we applied the Kruskal-Wallis non-parametric test. Also because of the small population, we used a broader than usual level of significance (critical p = 0.1). RESULTS: The application of the three tests for normality and the non-parametric test of significance by the Kruskal-Wallis technique showed that acute musical auditory stimulation with heavy metal music lead to a significant increase (p < 0.07) in one of the seven combinations of chaotic globals. The most significant combination of chaotic globals is the Chaos Forward Parameter One (CFP1), which includes all three studied chaotic globals (high spectral detrended fluctuation, high spectral entropy, spectral multi-taper method). We found significantly increased values during musical auditory stimulation for this specific CFP1. CONCLUSION: It is suggested that acute musical stimulation with heavy metal influences cardiac autonomic regulation at a more complex level than previously reported and that this may be beneficial to heart function.

OBJETIVO: A estimulação auditiva com música relaxante pode melhorar a regulação autonômica cardíaca em indivíduos tratados com um medicamento cardiotóxica. Avaliamos o efeito agudo de música heavy metal sobre a regulação autonômica cardíaca, por meio de novas técnicas de análise, ditas globalmente caóticas de espectrais altos: (a) high spectral detrended fluctuation, (b) high spectral entropy (c) spectral multi-taper method. MÉTODO: Estudamos mulheres jovens entre 18 e 30 anos de idade expostas a música heavy metal (75-84 dB) durante 20 min. Foram aplicados os seguintes testes de normalidade: (i) Anderson-Darling, (ii) Ryan-Joiner (similhante ao de Shapiro-Wilk); (iii) Lilliefors para baixo número de indivíduos. Todos indicaram que os dados obtidos apresentavam distribuição não-normal. Consequentemente foi aplicado o teste não-paramétrico de Kruskal-Wallis. Por causa da pequena população, utilizou-se um nível de significância mais amplo do que o habitual (p crítico = 0,1). RESULTADOS: A aplicação dos três testes para normalidade e o teste não-paramétrico de significância pela técnica de Kruskal-Wallis mostrou que a estimulação auditiva musical aguda com metais pesados produziu um aumento significativo (p < 0,07) em uma das sete combinações de globais caóticos. A combinação de globais caóticos que é mais importante é a "Chaos Forward Paremeter one" (VFP1) na qual se manifestam todos os três globais caóticos aplicados (high spectral detrended fluctuation, high spectral entropy, spectral multi-taper method). Encontramos um aumento significativo durante a estimulação auditiva musical para este parâmetro específico. CONCLUSÃO: Sugere-se que a estimulação musical aguda com heavy metal influencia a regulação autonômica cardíaca em um nível mais complexo e pode ser benéfica para a função cardíaca.

The Effects of Musical Auditory Stimulation of Different Intensities on Geometric Indices of Heart Rate Variability.

BACKGROUND: Music has been proven to promote changes in cardiac autonomic modulation. However, it is not clear whether the effects of the auditory stimulation on heart rate variability (HRV) are dependent on its intensity. OBJECTIVE: The study intended to investigate the acute effects on the geometric HRV indices of auditory stimulation with heavy metal and baroque music using different intensities of auditory stimulation. DESIGN: The study was a nonrandomized, clinical trial. SETTING: The study was conducted at the facility of the Faculty of Sciences of the São Paulo State University, on the campus in Marilia, Brazil. PARTICIPANTS: Participants were 24 healthy women aged between 18 and 27 y. INTERVENTION: HRV was recorded for each participant for 10 min at rest. Subsequently, participants were exposed to baroque or heavy metal music through an earphone. They were exposed to 3 equivalent sound levels-60-70 decibels (dB), 70-80 dB, and 80-90 dB-for 5 min in each intensity range. After the first session of baroque or heavy metal music, participants rested for an additional 5 min. Then they were exposed to the other musical style. The first style played for each musical period was randomly selected for all individuals and then the other style would be played automatically for the second session. OUTCOME MEASURES: The HRV analysis was performed using the following geometrical methods: (1) the triangular index (RRtri), (2) the triangular interpolation of the RR interval histogram (TINN), and (3) the Poincaré plot, using SD1-the standard deviation of the instantaneous variability of the beat-to beat heart rate (HR), SD2-the standard deviation of the long-term, continuous, RR interval variability, and the SD1/SD2 ratio-the ratio between the short- and long-term variations among the RR intervals. RESULTS: The classic baroque music by Johann Pachelbel, "Canon in D Major," did not induce significant changes in the geometric indices of HRV at 60-70 dB, 70-80 dB, or 80-90 dB. However, auditory stimulation with heavy metal music, using "Heavy Metal Universe" by Gamma Ray, decreased the RRtri, TINN, and SD2 at 2 specific sound pressures (60-70 dB and 80-90 dB). CONCLUSIONS: Auditory stimulation with the selected baroque music did not alter cardiac autonomic modulation, but the selected, heavy metal style of music in the lower and higher intensities reduced the global component of HRV acutely.

Neurophysiological aspects of musical auditory stimulation on the cardiovascular system / Aspectos neurofisiológicos do estímulo auditivo musical sobre o sistema cardiovascular

INTRODUCTION: The literature has shown that musical stimulation can influence the cardiovascular system, however, the neurophysiological aspects of this influence are not yet fully elucidated. OBJECTIVE: This study describes the influence of music on the neurophysiological mechanisms in the human body, specifically the variable blood pressure, as well as theneural mechanisms of music processing. METHODS: Searches were conducted in Medline, PEDro, Lilacs and SciELO using the intersection of the keyword "music" with the keyword descriptors "blood pressure" and "neurophysiology". RESULTS: There were selected 11 articles, which indicated that music interferes in some aspects of physiological variables. CONCLUSION: Studies have indicated that music interferes on the control of blood pressure, heart and respiratory rate, through possible involvement of limbic brain areas which modulate hypothalamic-pituitary functions.Further studies are needed in order to identify the mechanisms bywhich this influence occurs.
