Tolerance Testing

Objective Previous studies suggested that being postmenopausal could increase the risk of cardiovascular disease(CVD). If we can master the change characteristics of postmenopausal women’ cardiovascular function when they doing exercise, we may prevent or reduce the risk of CVD which induced by exercise. To get a more accurate tolerant judgment of the intensity of exercise, we discussed the change of cardiovascular function in sedentary postmenopausal women during exercise tolerance testing after exercise intervention, wish to provide more reliable theory basis in preventing exercise emergence and make an appropriate exercise prescription. Methods Thirty postmenopausal women participated the study. PAR-Q questionnaires and International Physical Activity Questionnaire-Short Forms were used to screen participants. They were randomly divided into control group(n=15) and experimental group (n=15). The experimental group had an exercise intervention with 3 months walking while the control group lived as usual. Using an exercise tolerance testing by cycle ergometer, let participants do one-time maximal graded exercise test to exhaustion, get the indicators of heart rate, blood pressure, VO2max, then analyzed the changes of cardiovascular function indexes before and after exercise intervention in experimental group, compared with control group in the same age categories, explored the similarities and differences between index variation. Results (1) After 3 months of exercise intervention, the rest systolic blood pressure in the experimental group was significantly lower than that in the control group(P<0.05). (2) With the increase of exercise intensity, heart rate tend to rise in both two groups (P<0.05). After 3 months of exercise intervention, the amplitude of heart rate variation between two intensities got smaller in the experimental group. (3) With the enlargement of exercise intensity, systolic blood pressure tend to increase in both two groups (P<0.05). After 3 months of exercise intervention, the amplitude of systolic blood pressure variation between two grades got smaller in the experimental group. (4) The exercise intervention can effectively improve the cardiac functional capacity of postmenopausal women (P<0.05). Conclusions Exercise for 3 month can efficiently increase the ability of postmenopausal women’s cardiovascular system in the quiet state, increase the reaction and adaptability of intensity stimulation of heart.

AbstractRecently, it has been reported that tear osmolarity (Tosm) is correlated with plasma osmolarity and will increase during exertion. We aimed to assess whether inhaling oxygen-enriched air between exercises could significantly change the Tosm value. Thirty men aged 24.9 years were included in the study. A cycloergometer was used to perform the exercise protocol. We recorded the participants’ Tosm (mOsm/L), heart rate (HR, beats/minute), oxygen saturation, and blood pressure values. After the first exhaustive exercise (T1), participants inhaled oxygen in the experimental group and a placebo in the control group. After the second exercise (T2), another set of measurements was obtained. The Tosm value before exercise was 297.4 ± 1.21 and 296.53 ± 1.11 mOsm/L (p = 0.61718) and the HR was 72.6 ± 2.59 and 73 ± 2.59 beats/minute (p = 0.39949) in the study and the control group, respectively. At T1, Tosm was 303.67 ± 1.25 and 302.2 ± 1.25 mOsm/L (p = 0.41286) and the HR reached 178.04 ± 2.60 and 176.4 ± 2.60 beats/minute (p = 0.65832), respectively. At T2, Tosm in the study group reached 305.73 ± 0.86 mOsm/L (correlation with the use of oxygen: r = −0.3818), and in the control group, it was 308.4 ± 0.86 mOsm/L (p = 0.0373), while the HR reached 172.20 ± 2.53 beats/minute in the study group and 178.2 ± 2.53 beats/minute in the control group (p = 0.057). It was concluded that inhaling oxygen before and after exercise could increase the rate of recovery after exhaustive exercise.

A stroke is a condition that can give rise to consequences such as cognitive and physical constraints, which sometimes manifest in the psychological condition of the patient. Such patients commence rehabilitation as soon as is possible, which involves a multi-disciplinary approach to treatment. One aspect of complementary rehabilitation could be animal-assisted therapy (AAT). A total of 15 individuals were split into an experimental group comprising 6 patients (2 males, 4 females), and a control group of 9 patients (3 males, 6 females). The participants in the control group were aged from 43 to 87 years and the experimental group featured participants aged from 45 to 76 years. Both groups received standard physiotherapy and occupational therapy. In addition, the experimental group was supplemented with AAT, with the animal in question being a dog. The tools primarily applied to measure the outcomes were the Barthel index, blood pressure, and heart rate measurements, whereas the Likert scale was employed to discern the mood of the patients. The results showed that changes in the values for heart rate and blood pressure were insignificant. However, a statistically significant aspect of the research pertained to the patients confirming that they felt better after the AAT sessions. Hence, AAT could potentially bolster the effectiveness of other therapies.

Abstract: Introduction: Patients who are undergoing cataract surgery under local anaesthesia may be more stressed than those having general anaesthesia as they are awake during the surgical procedure. Therefore, psychological comfort in the preoperative phase and compliance during operation are very important for postoperative prognosis. This study explored the pre operative anxiety level of patients undergoing cataract surgery and the effectiveness of intra operative hand holding on anxiety and its related physiological parameters. Methods: A quasi experimental pre-test post-test control group design was used to collect data from a purposive sample of 54 patients who were underwent cataract surgery at Kasturba Hospital, Manipal. Results: Most of the patients in the experimental group perceived intra operative hand holding as a measure to reduce their anxiety even though there was no significant statistical difference in the immediate post operative anxiety score between the groups. It was also found that hand holding was effective in reducing blood pressure and heart rate except the respiratory rate of patients undergoing cataract surgery. Conclusion: The following conclusions were drawn on the basis of the findings of the present study that is, Intra operative hand holding was effective in reducing the physiological parameters such as heart rate, systolic blood pressure and diastolic blood pressure. Also most of the patients perceived intra operative hand holding as beneficial in relieving anxiety.

This study aimed to evaluate the effect of transcutaneous electric acupoint stimulations (TEAS) on body composition and heart rate variability (HRV) in postmenopausal women with obesity. In this prospective study, 49 postmenopausal women were recruited in Taiwan. Body composition was used as a screening test for obesity (percentage body fat > 30%, waist circumference > 80 cm). The experimental group (n= 24) received TEAS treatment 30 min twice per week for 12 weeks at the Zusanli (ST 36) and Sanyinjiao (SP 6) acupoints. The control group (n= 25) did not receive any intervention. The study of HRV was analyzed by time (standard deviation of the normal-to-normal (NN) intervals (SDNN) and square root of the mean squared differences of successive NN intervals (RMSSD) indices) and frequency domain methods. Power spectral components were obtained at low (LF) and high (HF) frequencies. Body composition and HRV values were measured at the 4th, 8th, and 12th weeks. A total of 40 subjects completed this study. Waist circumference and percentage body fat in the experimental group (n= 20) were significantly less than those of the control group (n= 20) at the 8th and 12th weeks (allP< .05). Additionally, at the same time points, percentage lean body mass in the experimental group was significantly greater than that in the control group (P< .05). SDNN values increased significantly at the 4th and 8th weeks when compared with the control group (allP< .05). At 12 weeks, SDNN value was not significantly different from that of the control group (P= .105). TEAS treatment improves body composition, and has a transient effect on the HRV in postmenopausal women with obesity.

Long-term hospital stays might have a negative psychosocial impact on our patients. One way to positively activate hospitalized patients is to introduce animal-assisted therapy (AAT). A total of 72 individuals participated in this research. The experimental group comprised 33 patients (8 males, 25 females), while the control group contained 39 patients (11 men, 28 women). The participants in the control group were aged from 58 to 100 years and the experimental group featured participants aged from 51 to 95, for whom AAT was included alongside standard care. Blood pressure, heart rate, Barthel index, and general mood were measured in both groups. Results did not reveal any changes in blood pressure, heart rate, or Barthel index in comparison between groups. A great influence was noted in assessment of the mood of the patients. The inclusion of AAT did not affect physiological parameters, but it exerted a significant effect on the psychological well-being of the patients.

Purpose: This study was done to examine the effects of auricular acupressure (AA) on blood pressure (BP) and stress responses in adults with prehypertension.Methods: This single-blind, randomized, placebo-controlled study was conducted from September 2019 to February 2020. Participants were recruited through bulletin board notices in D city. The experimental group (n=27) received 8 weeks of AA intervention on specific acupoints (shenmen, kidney, heart, occiput, adrenal gland) to reduce blood pressure and stress, whereas the control group (n=25) received AA unspecific acupoints (helix 1-5). The outcomes were measured using BP, perceived stress scale (PSS), cortisol, and heart rate variability (HRV). Collected data were analyzed using Fisher’s exact test, chi-square, Shapiro-Wilk normality test, paired t-test, independent t-test, Mann-Whitney U test, repeated measures ANOVA and Friedman test with the SPSS/WIN 24.0.Results: Statistical differences were found between the groups for systolic BP (x2=85.64, p<.001), diastolic BP (x2=27.76, p=.001), PSS (F=9.439, p=.003), low frequency (F=5.22, p=.027), heart rate (F=3.208, p=.045), and HRV index (F=3.579, p=.035). Cortisol did not differ significantly between the experimental group and control group.Conclusion: The findings show that AA leads to improvements in BP and stress responses in adults with prehypertension. Therefore, AA can be used as an alternative nursing intervention for hypertension prevention and stress management.

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.

Traumatic brain injuries (TBI) represent a high impact public health problem due to a high rate of death , long term disability and occurrence especially in young adults. Despite several promising animal studies, several parameters were proposed as biological markers and were assessed for this aim. Our study proposes the study of the early biochemical changes in association to hematological parameters for severe TBI patients prognosis. 43 patients with acute TBI were included in study based on clinical, laboratory and imagistic findings. The severity of the TBI was established by Glasgow Coma Scale GCS 3-8. In all patients were evaluated hematologic parameters (Red blood cell count - RBC, Hematocrit, blood Hemoglobin, White blood cell - WBC, Platelet count and biochemical parameters (glucose, urea, creatinine, electrolytes). Outcome was expressed as Glasgow Outcome Scale (GOS), between 1-5. Values were compared to control group -15 cases. Significant early differences in body temperature, heart rate, and systolic blood pressure were observed in TBI group versus control (p[0.05). After correlation, laboratory findings significantly associated to severe outcome - GOS = 1, 2 - (p[0.05) were plasma Na decrease and significant glucose increase. An early increase of temperature and decrease of Na may predict a severe outcome in patients with acute TBI; association with shifts in heart rate and blood pressure, imposes aggressive treatment measures.

Postmenopausal women have a higher prevalence of hypertension compared to premenopausal women. Hypertension is a risk factor for cardiovascular diseases, the prevalence of which is ever increasing. This study investigated the effects of long-term acupuncture on lowering the blood pressure of postmenopausal women with prehypertension and stage 1 hypertension. Participants were 122 postmenopausal women aged less than 65 years, diagnosed with prehypertension or stage 1 hypertension (systolic blood pressure 120–159 mmHg or diastolic blood pressure 80–99 mmHg). We used a propensity score-matched design. The experimental group (n = 61) received acupuncture for four weeks every six months over a period of two years. The control group (n = 61) received no intervention. An Analysis of covariance (ANCOVA) was performed for the primary efficacy analysis. Relative risk ratios were used to compare group differences in treatment effects. Acupuncture significantly reduced the participants’ diastolic blood pressure (−9.92 mmHg; p < 0.001) and systolic blood pressure (−10.34 mmHg; p < 0.001) from baseline to follow-up. The results indicate that acupuncture alleviates hypertension in postmenopausal women, reducing their risk of developing cardiovascular diseases and improving their health and quality of life.

Abstract Background Endotracheal intubation and extubation may cause undesirable hemodynamic changes. Intravenous oxycodone has recently been introduced and used for relieving hemodynamic alterations in response to intubation, but there is insufficient information regarding its application in stabilizing hemodynamics during extubation in the patients emerging from general anesthesia. Methods One hundred patients, who had undergone assorted laparoscopic surgeries under general anesthesia, were randomly assigned to Control group (saline injection, 50 cases) and Study group (intravenous injection of 0.08 mg/kg oxycodone immediately after completion of the surgical procedure, 50 cases). Blood pressure, heart rate, blood oxygen saturation (SpO2) as well as blood concentrations of epinephrine, norepinephrine, and cortisol were recorded or measured immediately before extubation (T0), during extubation (T1), as well as one minute (T2), 5 min (T3), and 10 min after extubation (T4). In addition, coughing and restlessness, time of eye-opening, and duration from completing surgery to extubation as well as Ramsay Sedation Scale were analyzed. Results Blood pressure and heart rate as well as blood concentrations of epinephrine, norepinephrine, and cortisol were significantly higher in the Control group compared with the Study group at the time of extubation as well as 1, 5, and 10 min after extubation (P < 0.05). When the patients emerged from general anesthesia, 70 % of the Control group had cough, which was significantly higher than that of Study group (40 %, P < 0.05). Significantly higher number of patients manifested restlessness in the Control group before (40 %) and after extubation (20 %) compared with that in the Study group (20 and 2 %, respectively, P < 0.05). In addition, patients of Control group had lower Ramsay score at extubation (1.7 ± 0.7) as well as 30 min after extubation (2.4 ± 0.9) compared to that of the patients of Study group (2.2 ± 0.9, and 3.0 ± 0.8, respectively, P = 0.003 and 0.001). Conclusions Intravenous oxycodone attenuated alterations of hemodynamics and blood hormones associated with extubation during emergence from general anesthesia.
