Aim: The objective of the study was to compare the impact of daily 10 min humming practice for one week on heart-brain coherence and attention on college students. Methodology: The evidence indicates that increased heart-brain coherence facilitates better emotional regulation and thereby increases attention. Simple humming practice was identified as a method to increase the heart-brain coherence. Each student was assigned randomly to an experimental group or control group. The experimental group (n= 15) performed 10-minutes humming daily for 7 days and the control group (n=15) was not asked to do anything. 10-minute humming was simplified Bhramari practice with total breath duration of 13 seconds based on short training. SDMT (Symbol Digit Modalities Test) and Heart Brain Coherence (using Emwave Pro Device by HeartMath Inc.) was conducted for both the groups on Day 1 and Day 7. Statistical analysis was conducted using student-t test to understand the results. Results: For the experimental group, there was statistically significant improvement in both “Coherence” and “SDMT” score on Day 7 (compared to Day 1, p<.05). For control group, the change in both parameters was not statistically significant. Conclusions: The results confirm that a short duration humming practice just for one week can increase the heart-brain coherence and Heart Rate Variability and has a significant impact on increasing attention amongst the college students. These findings can be leveraged to facilitate better concentration and potentially increased performance for college students.

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.

Background. Searching for new strategies for the rehabilitation of adolescents with obesity and comorbid arterial hypertension (AHT) before significant pathological changes development in the cardiovascular system remains the urgent challenge. Objective. The aim of the study was to examine the effect of interval hypoxic training (IHT) on blood pressure (BP) levels in adolescents with overweight / obesity and comorbid AHT. Methods. Adolescents aged 14-17 years with body mass index SDS ≥ 1 and grade I AHT (mean level of systolic and/or diastolic BP ≥ 95th percentile for population of corresponding age, sex and height) have been randomized to the group «aerobic training» (treadmill walking) and “aerobic training + IHT” (usage of hypoxicator in intermittent operation cycles). All patients were on subcaloric diet (10% reduction in caloric intake for given age). Primary outcome measure was the difference between groups on systolic/diastolic BP levels according to 24-hour BP monitoring after completion of training program (10 classes each). The effects of IHT on body composition (bioelectrical impedance analysis), heart rate variability and psychoemotional state (Spielberger scale, assessment of health, activity and mood) were further estimated. Results. 43 patients were assigned to the index group, and 42 — to the control group. 67 patients have completed the research program. 5 patients (12%) from the IHT group and 13 patients (31%; p = 0.029) from the control group prematurely discontinued participation in the trial due to poor exercise tolerance. The groups were comparable in baseline systolic and diastolic BP. Decrease in BP occurred in both groups after 10 workouts. There were no differences in decrease value: mean difference for SBP was 2.4 mm Hg (95% CI -6.6 ... 1.8), for DBP — 0.2 mm Hg (-3.6 ... 4.0). However, the incidence of reaching the targeted SBP (< 95th percentile for the corresponding age and sex) after completion of the treatment was recorded in 66% patients in the experimental group and in 42% patients in the control group (p = 0,047). Positive dynamics in several indicators of heart rate variability and psychoemotional state were mentioned in the IHT group. Conclusion. The IHT implementation in the complex of rehabilitation program for adolescents with overweight / obesity and AHT has no additional positive effect on BP levels. However, the incidence of reaching the targeted SBP (< 95th percentile for the corresponding age and sex) after completion of the treatment was recorded in 66% patients in the experimental group and in 42% patients in the control group (p = 0,054).

Background: Autonomic dysfunction, cognitive impairment, and psychological distress are associated with poorer prognosis in patients with acute ischemic stroke (AIS). Heart rate variability (HRV) biofeedback (BF) improves autonomic dysfunction, cognitive impairment, and psychological distress in other patient populations, but its effect in patients with AIS is still unclear. Objective: This study investigated the effects of an HRVBF intervention on autonomic function, cognitive impairment, and psychological distress in patients with AIS. Method: In this randomized, controlled, single-blind trial, patients with AIS were randomly assigned to the experimental or control group. The experimental group received four HRVBF training sessions. The control group received usual care. Repeated measures of HRV, mini-mental status examination (MMSE), and Hospital Anxiety and Depression Scales (HADS) were collected prior to and at 1 and 3 months postintervention. Results: A total of 35 patients completed the study (19 experimental, 16 control). HRV and HADS significantly improved in the experimental group ( p < .001) but not in the control group. Likewise, only the experimental group showed significant improvements in HRV, MMSE, and HADS over time ( p < .05). Conclusion: HRVBF is a promising intervention for improving autonomic function, cognitive impairment, and psychological distress in patients with AIS. More studies of HRVBF interventions are needed to further optimize the effects of HRVBF on autonomic, cognitive, and psychological function in patients with AIS.

Aim. The article deals with establishing the efficiency of applying control and measuring indexes at Physical Education classes (physical development indexes, heart rate variability) as factors of health development and academic performance assessment. Materials and methods. We examined 20 fifth-grade male pupils (n = 20) from school No 90 (Togliatti), who formed  the basic experimental group and followed a correction and development program. We also examined pupils of the same gender, age, and number at school No 91 (Togliatti) to form the control group with a standard school program. The following methods of diagnostics were used: a computer program ‘Express Assessment of Pupils’ Physical Health’ and heart rate variability assessment by means of Varicard 2.51 hardware and software complex. Results. The article provides the experimental justification of using the dynamics of functional indicators (physical development indexes, heart rate variability) as control and measuring indexes at Physical Education classes. We established that at the initial stage of the pedagogical experiment there were no significant differences between the indicators of physical health in the experimental and control groups. In the experimental group, after lessons, including the selection of correction and development exercises depending on physical development indexes and heart rate variability, we registered a significant improvement of the parameters studied. In the control group, there were no significant changes in physical development or health status. Therefore, physiological markers provide a maximal objectivation of physical development, health, and academic progress assessment in pupils at PE lessons. Conclusion. Measuring physical development and health indexes in screening mode allows: 1) to perform a dynamic control of children ontogenesis, 2) to detect and promptly prevent dysontogenesis, 3) to prevent schoolchildren’s disadaptation after overloads.

Simulated Scenario

IntroductionThe use of different methods for introducing the scenario in simulation-based medical education has not been investigated before and may be a useful element to optimise the effectiveness of learning. The aim of this study was to compare an immersive video-assisted introduction to a minimal text-based one, with regard to emotional assessment of the situation.MethodsIn this pilot study, 39 students participated in a medical simulated scenario. The students were randomly assigned to an experimental group (video-assisted introduction) or a control group (minimal textual introduction) and both were followed by performing surgery on LapSim (Surgical Science, Gothenburg, Sweden). The emotional assessment of the situation, cognitive appraisal, was defined as the ratio of the demands placed by an individual’s environment (primary appraisal) to that person’s resources to meet the demands (secondary appraisal). Secondary outcomes were anxiety (State-Trait Anxiety Inventory), physiological parameters (heart rate, heart rate variability, skin conductance, salivary cortisol), engagement (Game Engagement Questionnaire), motivation (Intrinsic Motivation Inventory) and performance (mean score in percentage calculated by LapSim of predefined levels).ResultsParticipants in the immersive video group (n=17) were overloaded in terms of their perceived demands (a ratio of 1.17, IQR 0.30) compared with those in the control group (a ratio of 1.00, IQR 0.42, n=22) (P=0.01). No significant differences were found between the groups in secondary outcomes. Both groups showed an increase of anxiety after the introduction method. In the experimental group, this score increased from 9.0 to 11.0, and in the textual group from 7.5 to 10.5, both P<0.01.DiscussionThis study shows that the method of introducing a simulated scenario may influence the emotional assessment of the situation. It may be possible to make your simulation introduction too immersive or stimulating, which may interfere with learning. Further research will be necessary to investigate the impact and usefulness of these findings on learning in simulation-based medical education.

The Impact

Contemplative practices promote well-being, work engagement and resilience among health care providers. We examined the impact of The Pause, a brief contemplative intervention, on health care providers’ physiological stress response. Participants were randomly assigned to either The Pause or the control group. They participated in a high-fidelity, stressful medical simulation. Following the simulation, intervention group practiced The Pause. Outcome measures were heart rate variability, heart rate, and blood pressure. We adjusted for baseline physiological variables, sociodemographic variables, self-care practices, and perceived stress. Participants in the intervention group had a standard deviation of the normal-to-normal RR intervals (heart rate variability indicator) that was 13.8 (95% CI 4.0, 23.5; p < .01) points higher than those in the control group. There were no significant effects of The Pause on heart rate or blood pressure. The Pause may reduce stress reactivity, increase heart rate variability, and enhance resilience in health care providers.
