Purpose The purpose of this study is to develop a prototype of a novel respiratory device that we validated and assessed clinically and examined the effect of prototype of respiratory device on blood pressure (BP). Methods Prototype of respiratory device (TU-Breath Training) was designed with pressure cuff and application software was created. The immediate effect of resisted breathing was determined in 20 adults with high BP (systolic BP ≥ 130 mmHg and diastolic BP ≥ 90 mmHg). A crossover study was designed. A total of 20 eligible participants were asked to sit quietly for 10 min. Heart rate (HR), BP, and oxygen saturation (SpO2) were measured and recorded. After the resting period, all participants were randomized and counterbalanced for undergoing the set of inspiratory muscle training by TU-Breath Training and control group. A set of respiratory training were composed of 10 times per set for three sets, while the control group was asked to sit for 10 min. Results After inspiratory training, both the systolic and diastolic BP decreased significantly. Compared with control group, using TU-Breath Training decreased systolic BP (−7.00 ± 5.93 mmHg) and diastolic BP (−5.95 ± 8.88 mmHg), but did not show differences in HR and SpO2. Conclusion The study indicated that in high-BP participants, the prototype of respiratory device (TU-Breath Training) elicits decreased BP.

Study Intervention

UNSTRUCTURED Lifestyle interventions have been recognised as a line treatment of non-communicable diseases. The aimed of this study was to evaluate a bespoke mHealth approach to delivers personalised feedback to improve blood pressure and weight for hypertensive patients in community settings. A total of 307 participants, 50 from each community, were expected to be in the intervention or control group. A professional health facilitator was assigned for each of the 6 communities. The primary outcomes of the study are the reduction in blood pressure and weight at baseline and post-intervention. Of 307 recruited,192 (62.5%) participants completed the study (intervention: 104 and control: 88). There was no difference in attrition rates between the two groups (33.5%vs41.9%, p=0.291). After 6-months of intensive feedback intervention through mHealth approach, patients had better blood pressure, weight, and BMI compared with control. People who were adherent to the intervention demonstrated a clinical benefit with regards to weight and blood pressure.

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.

Cardiovascular disease (CVD) is a major cause of death in developed countries. Most cardiac rehabilitation programs include psychological interventions. The aim of this study was to determine the effectiveness of rehabilitation techniques in cardiac patients including psychological-physical interventions such as Meditation and Relaxation. We enrolled 45 patients with CVD and depression. The patients were allocated to 3 groups (Relaxation, Meditation and Control). There was a significant reduction on depression, systolic blood pressure and heart rate in the Meditation group compared with the control group. Our findings suggest that meditation techniques have better outcomes in cardiac patients for improving depression, reduction of systolic and diastolic blood pressure, and heart rate than relaxation techniques.

Background and Study Aim. This study was to investigate the effects of low-intensity interval training on the physiological variables of university students. Material and Methods. Forty male sports science students aged 18-25 years were randomly assigned to the Experimental group (n=20) and the Control group (n=20). The Experimental group underwent low-intensity interval training for eight weeks, whereas the Control group did not. Measurements of physiological variables such as resting heart rate, respiratory rate, recovery heart rate, breath-hold time, maximal oxygen uptake, and blood pressure were obtained for all subjects before and after the intervention. To compare the mean physiological variables between the experimental and control groups, an independent samples t-test was used. Results. Statistical significance was set at p 0.05. After the training intervention, the experimental group showed significantly better improvements than the control group in resting heart rate, respiratory rate, recovery heart rate, breath-holding time, maximal oxygen uptake, and blood pressure (p 0.05). Post intervention maximum oxygen uptake was statistically significant with t (38) = 3.086, p value 0.004. Post experiment systolic blood pressure was statistically significant with t (38) = -2.405, p value 0.021 for low intensity interval training and control group. Post experiment diastolic blood pressure was statistically highly significant with t (38) = 0.569, p value 0.001 for low intensity interval training and control group. The result of the study showed that there was a significant difference in post rest heart rate, respiratory rate, recovery heart rate, systolic blood pressure, diastolic blood pressure, breath holding and maximal oxygen uptake between the low intensity interval training and the control group (p 0.05). Conclusions. Thus, it was concluded that eight weeks of low-intensity interval training show significant improvement in physiological variables of university students.

Introduction: The use of epinephrine for controlling the blood loss has gained out in many dermatological surgeries; however, its use in liposuction has not been studied. In this regard, we aimed to figure out the effectiveness of using epinephrine in tumescent solution during liposuctions surgery. Material and Methods: In this study we present a prospective, double-blind, nonrandomized study evaluating the effects of adding epinephrine to tumescent solution intra-operative in patients undergoing liposuction. Thirty-six patients including 6 males and 29 females undergoing liposuction were divided into two groups. In case group we use 1-1.4 mg/L epinephrine (based on the location of surgery) in tumescent solution; and control group did not receive epinephrine. Lab data such as hemoglobin and hematocrit as well as clinical data including blood pressure and heart rate were recorded before, after 1h and 6h of liposuction.  Results: In this study, we observed that both case and control group faced a significant dropped in their hemoglobin and hematocrit; however, the decrement was significant lower in case group. In addition, both groups had a stable hemostasis after 1h and 6h of surgery. In this regard, we did not observe any significant difference between heart rate and blood pressure of two groups. Conclusion: The results of this study suggest that using epinephrine as vasoconstriction agent in tumescent solution might decrease the rate of bleeding and increase the chance of stable hemostasis both during and after abdominal liposuction.

Background Clonidine reduces heart rate (HR) responses to atropine, whereas neostigmine causes bradycardia. This study was designed to determine whether clonidine premedication would reduce tachycardia after neostigmine-atropine administration. Methods Fifty adult patients without cardiovascular disorders who were scheduled for elective surgeries were randomly assigned to receive approximately 5 microg/kg (oral clonidine clonidine group, n=25) or no clonidine (control group, n=25) 90 min before induction of general anesthesia. After tracheal intubation, anesthesia was maintained with N2O and 12% isoflurane in oxygen while patients were paralyzed with vecuronium and mechanically ventilated. When surgeries were completed, adequate spontaneous respiration, responses to verbal commands, and sustained tetanus by stimulating the ulnar nerve were confirmed, and patients' tracheas were extubated. Then a mixture of 0.05 mg/kg neostigmine and 0.02 mg/kg atropine was administered intravenously over 20 s under stable hemodynamic condition (systolic blood pressure and HR within +/-5% of preceding values), and blood pressure and HR were measured noninvasively at 1-min intervals for 10 min. Results Increases in HR in the clonidine group were significantly less 1-4 min after neostigmine--atropine injections compared with HR values in the control group. A maximum increase in HR of the clonidine group was also significantly less than the control group (15+/-7 vs. 23+/-10 beats/min; means+/-SD), whereas absolute values of mean blood pressure were similar. Severe bradycardia (HR &lt; 50 beats/min) developed in no patients in either group. Conclusions Premedication with 5 microg/kg oral clonidine attenuates the initial increases in HR without subsequent decreases in HR.

Abstract Objectives Sheetali pranayama, a cooling pranayama is best known for its calming and relaxing nature, widely used for many conditions like depression, anxiety and hypertension. The aim of the study was to evaluate the immediate effect of the practice of Sheetali pranayama on heart rate and blood pressure parameters in healthy volunteers. Methods Apparently, 60 healthy volunteers were involved, from both sexes. They were split into pranayama (n=30) and control (n=30) groups at random. Sheetali pranayama was performed for 5 min (5 cycles) in the pranayama group and normal breathing (12–16 breaths/min) was permitted in the control group. Heart rate (HR) and blood pressure (BP) were recorded with RMS polyrite in the supine position after 5 min of rest. Results The HR in the pranayama group significantly decreased (p=0.04). Systolic (SBP) and diastolic blood (DBP) pressure, pulse pressure (PP) and mean arterial pressure (MAP) decreased significantly (p<0.05) relative to control after pranayama practice. Pre-Post inter-group results has also shown that the pranayama group has substantially decreased HR and BP indices. Conclusions Present study shows that the practice of Sheetlai pranayama creates a relaxed state, and parasympathetic activity overrides sympathetic activity in this state. It indicates that in healthy volunteers, pranayama strengthens the resting cardiovascular parameters.

Objectives: (1) Identify laryngeal patterns axiomatic to exercise-induced laryngeal obstruction (EILO) and (2) investigate the role of autonomic function in EILO. Methods: Twenty-seven athletic adolescents (13 EILO, 14 control) underwent laryngoscopy at rest and exercise. Glottal configurations, supraglottic dynamics, systolic blood pressure responses, and heart rate recovery were compared between conditions and groups. Results: Inspiratory glottal angles were smaller in the EILO group than the control group with exercise. However, group differences were not statistically significant ( P > .05), likely due to high variability of laryngeal responses in the EILO group. Expiratory glottal patterns showed statistically greater abductory responses to exercise in the control group ( P = .001) but not the EILO group ( P > .05). Arytenoid prolapse occurred variably in both groups. Systolic blood pressure responses to exercise were higher in the control group, and heart rate recovery was faster in the EILO group. However, no significant differences were seen between the 2 groups on either autonomic parameter ( P > .05). Conclusions: “Paradoxical” inspiratory and blunted expiratory vocal fold pattern responses to exercise best characterize EILO. Group differences were only seen with exercise challenge, thus highlighting the utility of provocation and control groups to identify EILO.

We studied the effect of experimenter expectations and different instructions in a balanced placebo design. 157 subjects were randomized into a 2 × 4 factorial design. Two experimenters were led to expect placebos either to produce physiological effects or not (pro- vs. antiplacebo). All subjects except a control group received a caffeine placebo. They were either made to expect coffee, no coffee, or were in a double-blind condition. Dependent measures were blood pressure, heart rate, well-being, and a cognitive task. There was one main effect on the instruction factor (p = 0.03) with the group “told no caffeine” reporting significantly better well-being. There was one main effect on the experimenter factor with subjects instructed by experimenter “proplacebo” having higher systolic blood pressure (p = 0.008). There was one interaction with subjects instructed by experimenter “proplacebo” to receive coffee doing worse in the cognitive task than the rest. Subjects instructed by experimenter “antiplacebo” were significantly less likely to believe the experimental instruction, and that mostly if they had been instructed to receive coffee. Contrary to the literature we could not show an effect of instruction, but there was an effect of experimenters. It is likely, however, that these experimenter effects were not due to experimental manipulations, but to the difference in personalities.
