Associative Functions

Linguistic associative functions in disorders of consciousness patient (DOC) were studied in the present research by using autonomic measures (Skin Conductance Response, SCR; Heart Rate, HR). We intended to verify the preservation of semantic linguistic processes in Vegetative State (VS) and Minimal Consciousness State (MCS) by considering arousal modulation. Twenty-four patients and twenty controls were submitted to an auditory semantic task (congruous or incongruous word sequences). A similar increased SCR/HR was found for both DOC and control group in response to incongruous condition. This modulation was interpreted as a marker of the increased cognitive difficulty in processing and restoring incongruent information. However, MCS and VS groups quantitatively (but not qualitatively) differed in term of degree of increased arousal, since higher SCR and HR increasing was observed for MCS than VS. These results were interpreted as a marker that the semantic processing was partially preserved in both VS and MCS patients.

(1) Background: Research on heart rate variability has increased in recent years and the temperature has not been controlled in some studies assessing repeated measurements. This study aimed to analyze how heart rate variability may change based on environmental temperature during measurement depending on parasympathetic and sympathetic activity variations. (2) Methods: A total of 22 volunteers participated in this study divided into an experimental (n = 12) and control group (n = 10). Each participant was assessed randomly under two different environmental conditions for the experimental group (19 °C and 35 °C) and two identical environmental conditions for the control group (19 °C). During the procedure, heart rate variability measurements were carried out for 10 min. (3) Results: Significantly changes were observed for time and frequency domains as well as Poincaré plot variables after heat exposure (p < 0.05). These findings were not observed in the control group, whose conditions between measurements did not change. (4) Conclusions: The reduction of heart rate variability due to exposure to hot conditions appears to be produced mostly by a parasympathetic withdrawal rather than a sympathetic activation. Therefore, if consecutive measurements have to be carried out, these should always be done under the same temperature conditions.

The purpose of the present study was to investigate the effect of a scientic study on low and medium level of intense circuit training on selected physiological parameter among elite female athletes. To achieve the purpose of the study thirty female athletes were selected from Erode District, Tamilnadu, India during the year 2021. The subject’s age ranges from 21 to 25 years. The selected subjects were divided into two equal groups consists of 15 subjects each namely experimental group and control group. The experimental group underwent a combined low and medium level of intensity circuit training programme for eight weeks. The control group was not taking part in any training during the course of the study. Resting heart rate was taken as criterion variable in this study. The selected subjects were tested on resting heart rate was measured through heart rate monitor. Pre-test was taken before the training period and post- test was measured immediately after the eight week training period. Statistical technique‘t’ ratio was used to analyse the means of the pre-test and post test data of experimental group and control group. The results revealed that there was a signicant difference found on the criterion variable. The difference is found due to combined low and medium level of intensity circuit training given to the experimental group on heart rate when compared to control group.

In this research, heart rate variability (HRV), pulse rate variability (PRV) and human skin conductance (SC) of all acupoints on Heart Meridian were used to evaluate the effects of electrical acupuncture (EA) on acupoint BL15 (Bladder Meridian). Ten healthy volunteers (aged 23 ± 6) were selected as the control group on the first day, and then used again as the experimental group on the second day. The control group received sham EA during the study, while subjects of the experimental group were stimulated by 2 Hz EA on acupoint BL15 for 10 minutes. Electrocardiogram (ECG), wrist blood pressure pulse meter and skin conductance response (SCR) device were used to measure and analyze HRV, PRV and SCR for the two groups before and after stimulation. From the spectrum analysis of ECG and pulse pressure graph, we found that the EA applied on BL15 could induce a significant increase in the normalized high frequency power (nHFP) component of HRV and PRV, as well as a significant decrease in the normalized low frequency power (nLFP) part ( p < 0.05). Moreover, both the heart rate and pulse rate were reduced in the analysis of the time domain of ECG and PRV. Furthermore, most of the SCR values at acupoints were decreased after stimulation. These results also indicate that the stimulation of BL15 by EA could cause relaxation, calmness and reduce feeling of tension or distress.

To explore the effect of trimetazidine (TMZ) in cardiomyopathy treatment. Literatures, related with TMZ treatment for cardiomyopathy, were retrieved between 1990 and February 2018 in the Pubmed, Embase, and Cochrane Library systems. Cardiopulmonary exercise testing [resting heart rate (RHR), peak heart rate (PHR), peak systolic blood pressure (PSBP), and resting systolic blood pressure (RSBP)] and echocardiographic results [left ventricular ejection fraction (LVEF), left ventricular end-systolic volume (LVESV), left ventricular end-diastolic volume (LVEDV), systolic wall thickening score index (SWTSI), left ventricular end-systolic diameter (LVESD), and left ventricular end-diastolic diameter (LVEDD)] were merged to detect the publication bias. Total 898 patients with cardiomyopathy were divided into two groups: TMZ-treated group (n=456) and control group (n=442). There was no difference in the improvement of cardiomyopathy between the TMZ and control group. No publication bias was shown for PHR (t= 0.9791, P=0.5067). There were significant differences in LVEF, LVESV, SWTSI, LVESD, and LVEDD between the TMZ group and the control group. TMZ-treatment significantly increased the level of LVEF (95% confidence interval (CI): 5.46–7.84, P<0.001), and reduced the level of LVESV (95% CI: −18.73 to −7.77, P<0.001), SWTSI (95% CI: −0.47 to −0.15, Z = −3.85, P=0.001), LVESD (95% CI: −1.09 to −0.08, P<0.001), and LVEDD (95% CI: −0.55 to −0.26, P=0.023). There was no publication bias except for LVEDV (t = 2.5456, P=0.0438). TMZ is effective for cardiomyopathy treatment and worth to popularize in clinic.

Background: The safety of beta-blockers as a heart rate-limiting drug (HRLD) in patients with acute respiratory failure (ARF) due to chronic obstructive lung disease (COPD) has not been properly assessed in the intensive care unit (ICU) setting. This study aims to compare the use of beta-blocker drugs relative to non-beta-blocker ones in COPD patients with ARF due to heart rate-limiting with respect to length of ICU stay and mortality. Methods: We performed a retrospective (January 2011-December 2012) case-control study in a level III ICU in a teaching hospital. It was carried out in a closed ICU by the same intensivists. All COPD patients with ARF who were treated with beta-blockers (case group) and non-beta-blocker HRLDs (control group) were included. Their demographics, reason for HRLD, cause of ARF, comorbidities, ICU data including acute physiology and chronic health evaluation (APACHE II) score, type of ventilation, heart rate, and lengths of ICU and hospital stays were collected. The mortality rates in the ICU, the hospital, and over 30 days were also recorded. Results: We enrolled 188 patients (46 female, n = 74 and n = 114 for the case and control groups, respectively). Reasons for HRLD (case and control group, respectively) were atrial fibrillation (AF, 23% and 50%), and supraventricular tachycardia (SVT, 41.9% and 54.4%). Patients’ characteristics, APACHE II score, heart rate, duration and type of ventilation, and median length of ICU-hospital stay were similar between the groups. The mortality outcomes in the ICU, hospital, and 30 days after discharge in the case and control groups were 17.6% versus 15.8% (p > 0.75); 18.9% versus 19.3% (p > 0.95) and 20% versus 11% (p > 0.47), respectively. Conclusions: Our results suggest that beta-blocker use for heart rate control in COPD patients with ARF is associated with similar ICU stay length and mortality compared with COPD patients treated with other HRLDs.

Background. Cardiovascular system recovery after physical activity with explosive exercises is essential for cardiovascular pathology prevention. The efficiency of short-term biofeedback training (BFB training) in such conditions in adolescents have not been studied earlier. Objective. Our aim was to study the effect of BFB training on cardiovascular rehabilitation after speed and power training in adolescents according to general heart rate variability (HRV) spectrum total power parameter. Methods. The research has included healthy eighth-grade students (14–15 years old boys) from regular school. Inclusion in experimental and control groups was regulated by researches. Such indicators as total power (TP) of HRV spectrum, tension index (TI), systolic and diastolic arterial blood pressure (ABP), heart rate (HR) were registered initially, after three standing long jumps with double take-off and after recovery. All members of experimental group performed BFB training in order to increase TP (3 min) during recovery period. Members of control group were resting. Results. Initially all members of experimental (n = 17) and control (n = 10) groups were compared on age, height, weight and TP, TI, ABP and HR indicators. The TP level in boys of experimental group was higher than in control group during recovery period after BFB training: 3.22 (1.96; 6.13) against 1.36 (1.15; 1.84) X 1000 ms2 respectively (р = 0.041). There were no differences in TI, ABP and HR levels between two groups during recovery period. Conclusion. Implementation of short-term BFB training according to general HRV spectrum total power parameter in 14–15 years old boys after speed and power training perpetuates vagal impact on heart rate during recovery period.

Imagery is an important component in strategies for coping with pain. In this study, we examined, whether imagery influences tolerance for pain and whether subjects, trained in pain-incompatible imagery differ in heart rate and skin resistance from these in a control group during a pain-induction session. 39 subjects were randomly assigned to two groups: imagery and control. Both groups had two pain-induction sessions At intake into the study (t1), Pain Tolerance and Psychophysiological Reaction to Pain were assessed using a pressure algometer. After the first session, the experimental group received 1 hr. of training in pain-incompatible imagery. Seven days later, the session was repeated (t2). The results showed that Pain Tolerance was significantly increased in the group who used pain-incompatible imagery. One might follow the notion that increased Pain Tolerance is associated with increased Psychophysiological Pain Reaction, but results suggest the contrary. Subjects trained in pain-incompatible imagery had lower heart rates during the second pain induction than the control group. Groups did not differ with regard to skin resistance. It can be stated that besides information, cues on coping with pain may be helpful in clinical practice.

AbstractAim of the study: The aim of the study was to analyse anthropometric indicators, e.g. quiescent heart rate, quiescent respiratory rate and heart rate burden, in children with mental, hearing, visual disabilities participated in intervention programs of controlled physical activities. Material and methods: 180 children: 90 males, 90 females, aged 8-15 years, were divided in experimental and control samples according researched disabilities. Intervention method was realised in 10 months period. 3 times in 10 months of intervention program was provided an investigation, followed by data analysis. Relations of dependent variables to probands’ sex, to experiment and its exact phases were evaluated using repeated measures ANOVA, software Statgraphics Centurion. Results: A tendency for a decrease in quiescent heart rate and quiescent respiratory rate was found among both boys and girls from all experimental groups, whereas for the controls this value either stayed at baseline level or even increased. In the case of heart rate burden, the values significantly decreased for the experimental groups and increased for the control group members. Conclusions: The presented evaluation of the positive changes shows that the hypothesis has been verified in all three aspects. Significant positive changes were approved in the monitored indicators through the intervention programs of controlled physical activities in children with mental, hearing or visual disabilities. The results verified the specific prevention and treatment benefits of controlled physical activities in the child disability context in the important age period of 8-15 years.
