“…However, Mouridsen et al (51) reported that weight loss seems to improve HRV. A relationship between BMI and LF and HF band of the HRV spectrum was reported only in premenopausal women (18,52). The decrease of HF and increase of LF may be associated with central adiposity in postmenopausal women (53).…”

Original Investigation 11Autonomic control in CVS can be assessed by HRV analysis.Various time domain and frequency domain indices are usually used for this purpose (2). The physiological explanation of these indices is known (2,19,20). These indices can assess cardiac autonomic regulation but not peripheral blood flow. In our previous papers, we have proposed an original method for the assessment of cardiovascular autonomic control based on synchronization between the 0.1-Hz rhythms in heart rate (HR) and photoplethysmogram (PPG) (21). The quality of 0.1-Hz rhythms synchronization was found to be higher in healthy subjects than in patients with cardiovascular disease (22). From a physiological viewpoint, the synchronization of 0.1-Hz rhythms is the result of adequate functional interaction of CVS parts (heart and peripheral vessels). The clinical importance of this diagnostic method is shown for patients with prior myocardial infarction, patients with acute coronary syndrome, and hypertensive patients (3,23). The physiological explanation of 0.1-Hz rhythms in PPG is a debatable point. An opto-physiological model of a finger in conjunction with a near-infrared reflectance PPG device has been proposed (24). It was shown that both oscillations in the microcirculatory bed and blood filling of digital arteries make a substantial contribution to the PPG signal. Therefore, 0.1-Hz oscillations in PPG may be associated directly with baroreceptor regulation of blood pressure (BP). At the same time, a number of authors assume that 0.1-Hz oscillations in blood microcirculation are not associated with autonomic regulation (25)(26)(27)(28). To avoid confusion, we do not interpret the origin of 0.1-Hz oscillations in PPG in the present paper. Thus, the features of cardiovascular autonomic control in women before and after menopause are not fully understood. Controversial results concerning this problem have been reported. The aim of the present study cross-sectional study is to assess the features of autonomic control of CVS in pre-and postmenopausal women. Material and Methods PatientsThe study was approved by the ethics committee of the Saratov Research Institute of Cardiology in Saratov, Russia (no. 24, Sept. 12, 2013) and informed consent was obtained from all participants. Our cross-sectional study included 185 postmenopausal women aged 59.3±8.5 years (mean±SD) and 104 premenopausal women aged 45.1±5.8 years. Both groups were investigated and treated, if necessary, in the clinic of Saratov State Medical University (Saratov, Russia). Clinical characteristics (cardiovascular, gynecological, etc.) were assessed in all women. We assessed the level of the following sex hormones: estradiol, follicle-stimulating hormone (FSH), dehydroepiandrosterone sulfate (DHEAS), and testosterone. Only patients aged between 35 and 70 years were enrolled in our study. Women with CVD were not on beta-blockers or calcium channel blockers during the 7 days before the start of the study.Patients were not included in our study if they ...

“…The influence of sex hormones, in particular, hormone replacement therapy (HRT), on cardiovascular autonomic control is controversial (8,(12)(13)(14)(15)(16)(17). Moreover, several authors reported the influence of body mass index (BMI) on autonomic control in women (18).…”

“…Even in the case in which the substances are identified, there are cases of dispute and the few economic resources are used for further study on the same samples to athletes rather than new research. In addition, it is impossible to anticipate the moves of the opponent and this, therefore, is not easy to understand what new substances will be taken and what new methods will be adopted [36,69,70].…”

Aim: Doping affects the sport. Its explosive spread has triggered the response of sports' and government's institutions. The aims of this study were to know the spread of doping in Italy, what were the most used substances and/or method and in which sports it was more common. Moreover, what instruments were used to contrast it. Methods:We have analysed the doping's spread in Italy since 2003. The data come from the databases of government and sports Italians institutions. We have compared those data and focused our attention on substances and/or methods discovered in athletes. Furthermore, data's combination showed the reason of drug addiction. Results:In Italy, only 3% of checked athletes are doped, many of them are men and young athletes dope less than the older ones. Doped athletes play mainly cycling, athletics, swimming and football. The prominent peak of them is in the Central and Southern Italy in 2008 and 2010. Moreover, the analysis of data relating to galenic preparations declared during the year 2012, shows that 75% of the prescribed substances are diuretics and masking agents, anabolic steroids and stimulant. Regarding the substances, cannabinoids and stimulants have recorded the highest consumption. Conclusion:The data show only the tip of the iceberg due to doping's secrecy. Every substance that give pleasant sensations or help the subject in his activity will bring him to repeat the consumption. Frequently, new substances and methods are discovered. For this reason, to contrast this phenomenon, there are legislation instruments together with various funded projects.

“…The postmenopausal women are older than the premenopausal women. The age can influence the absence of statistical difference of heart rate variability between lean and obese groups in postmenopausal age observed in the report of Monda et al [1]. The values of heart rate variability measures decrease with the aging process for women and men [2].…”

In his letter, he states that our work confirms the results of previous reports in smaller groups of patients and comments about our selection criteria of obesity patients.Although we really did not include in the exclusion criteria the presence of respiratory disturbances, there was in our group just one patient with history of chronic pneumopathy. The others have no diagnosis of respiratory diseases.We described in our paper that the number of patients with antihypertensive drugs decreased from 25 to six patients 6 months after surgery. In his letter, Russo comments the absence of information about angiotensinconverting enzyme inhibitors (ACE inhibitors) and angiotensin II receptors blockers (ARBs), others drugs (steroid hormones, antidepressants, appetite suppressants), and smoking. In fact, we found in our group ten patients using ACE inhibitors before surgery and just one patient 6 months after surgery. Three patients were using ARBs before and none after. There were no patients using sex steroid hormones or appetite suppressants. No patient was using antidepressants before surgery and just one patient was using after (fluoxetine). Six patients were smokers before surgery and two patients stopped smoking after it.We did not consider, in our report, the fertility state of the women. The postmenopausal women are older than the premenopausal women. The age can influence the absence of statistical difference of heart rate variability between lean and obese groups in postmenopausal age observed in the report of Monda et al. [1]. The values of heart rate variability measures decrease with the aging process for women and men [2].We are glad to know that the preliminary data of Russo et al. are in accordance with our results. Thus, we think that the aspects commented on about our selection criteria did not have any influence over the results. gender, body mass index, and functional capacity on heart rate variability in a cohort of subjects without heart disease.
