The Relationship

1. The intensity of breathlessness during exercise was measured in ten normal subjects using a visual analogue scale (VAS) and a Borg scale to compare the use of the scales and their repeatability, both within the duration of a period of exercise and between tests. For each scale, subjects performed two exercise tests separated by a period of 2–6 weeks. Each exercise test consisted of two cycles of progressively increasing and decreasing workload. 2. All subjects felt confidently able to use both scales to quantify their feelings of breathlessness exclusively of other sensation. Equal preference was expressed for use of a particular scale. 3. With both scales there was a large intersubject variation in the relationship between dyspnoea score and minute ventilation (VE) (P < 0.01), and in the range of the scale used. 4. There was a good correlation between the VAS and Borg scores at each level of VE (r2 = 0.71), but the VAS score was used over a wider range than the Borg score. 5. The relationship between VE and the dyspnoea score measured by the two techniques was predominantly linear. The mean r2 for VAS score/VE was 0.68 (sd 0.19) and for Borg score/VE the mean r2 was 0.75 (sd 0.13). 6. The relationships VAS score/VE and Borg score/VE were unaffected by the direction in which the workload was varied (P > 0.05). 7. VE, measured at each work rate, did not differ between the two cycles (P > 0.05) or between the 2 days (P > 0.05). 8. With both scales, the slope of the VE-breathlessness relationship was slightly higher during the second half of the exercise compared with the first (0.05 < P > 0.01). 9. The scores with both scales were lower in the second test compared with the first (P < 0.01): Borg 16% lower, VAS 27% lower. 10. Measurements of dyspnoea made with the Borg scale appeared to have greater stability than VAS measurements and to correlate with VE a little better.

The Relationship

1. The intensity of breathlessness in normal subjects during exercise was measured on seven occasions over a 40-week study period to assess the long-term repeatability of Borg scale estimates of breathlessness. 2. In all subjects there was a significant correlation (P = 0.0001) between breathlessness and minute ventilation. Minute ventilation measured at each work rate did not differ between the seven exercise tests (P >0.05). 3. There was no significant difference between the mean Borg scores (measured with respect to a given level of ventilation) in 5 of the 7 test weeks (P >0.05). The slope of the relationship Borg score/minute ventilation did not differ between the seven exercise tests (P >0.05). 4. Breathlessness estimation was highly reproducible both after 1 week and after 40 weeks of the study (both P >0.05). 5. The duration without testing between consecutive tests did not affect reproducibility: the mean Borg score was as equally reproducible after an interval of 22 weeks without testing as after an interval of 1 week (P >0.05). 6. The Borg scale provides a reliable technique for studying the sensation of breathlessness over extended time periods.

Inspiratory Load

1. The intensity of breathlessness was measured during exercise in nine normal subjects using a modified Borg scale to examine the effect of prior experience of breathlessness on subsequent estimates of breathlessness. 2. Each subject performed four exercise tests, each of which consisted of two identical runs of workload incrementation (run 1 and run 2). An inspiratory resistive load of 3.8 cmH2O s−1 l−1 was applied during the appropriate run of the exercise test to examine the effect of (a) prior experience of ‘loaded’ breathing on breathlessness estimation during ‘unloaded’ breathing, and (b) prior experience of ‘unloaded’ breathing on breathlessness estimation during ‘loaded’ breathing. Run 1 was the conditioning run; run 2 was the run in which the effect of conditioning was measured. 3. There was a good correlation between breathlessness and minute ventilation during both unloaded’ breathing (median r = 0.93) and ‘loaded’ breathing (median r = 0.95). 4. The slope of the Borg score/minute ventilation relationship was greater during ‘loaded’ breathing than during ‘unloaded’ breathing (P < 0.01). There was no difference in mean Borg score between ‘unloaded’ and ‘loaded’ breathing. 5. After a period of ‘loaded’ breathing during run 1, estimated breathlessness was significantly reduced during ensuing ‘unloaded’ breathing in run 2 (P < 0.01) compared with the exercise test in which ‘unloaded’ breathing was experienced throughout both run 1 and run 2. 6. After a period of ‘unloaded’ breathing in run 1, estimated breathlessness was significantly increased during ensuing ‘loaded’ breathing in run 2 (P < 0.01) compared with the exercise test in which the inspiratory load had already been experienced in run 1. 7. Changes in the pattern of breathing (inspiratory time, expiratory time, total breath duration, inspiration time/total breath duration ratio and tidal volume) were not consistent with the changes in breathlessness. 8. We suggest that perception of breathlessness may be influenced by a subject's immediate prior experience of an altered relationship between breathlessness and ventilation.

Objectives: To analyze the reproducibility of the new iC100 rebound tonometer, to compare its results with the applanation tonometry and iCare PRO and to evaluate the preference between them. Materials and methods: For the study of reproducibility, 15 eyes of 15 healthy Caucasian subjects were included. Three measurements were taken each day in three separate sessions. For the comparative study, 150 eyes of 150 Caucasian subjects were included (75 normal subjects and 75 patients with glaucoma). Three consecutive measurements were collected with each tonometer, randomizing the order of use. The discomfort caused by each tonometer was evaluated using the visual analogue scale. Results: No statistically significant differences were detected between sessions. In the comparison between tonometers, the measurements with iC100 were statistically lower than those of Perkins (−1.35 ± 0.417, p = 0.004) and that iCare PRO (−1.41 ± 0.417, p = 0.002). The difference between PRO and Perkins was not statistically significant ( p = 0.990). The mean time of measurement (in seconds) with iC100 was significantly lower than with Perkins (6.74 ± 1.46 vs 15.53 ± 2.01, p < 0.001) and that PRO (6.74 ± 1.46 vs 11.53 ± 1.85, p < 0.001). Visual analogue scale score with iC100 was lower than Perkins (1.33 ± 0.99 vs 1.73 ± 1.10, p < 0.05). In total, 61.7% preferred iC100 against Perkins. Conclusion: The reproducibility of this instrument has been proven good. iC100 underestimates intraocular pressure compared to applanation tonometry at normal values and tends to overestimate it in high intraocular pressure values. Most of the subjects preferred iC100 tonometer.

1. This study was designed to examine whether normal subjects could differentiate between the ‘intensity’ of their breathlessness and the amount of ‘distress’ it evoked, by specific wording of the instructions. 2. A preliminary study showed no significant difference between ‘distress’ score during exercise measured on two separate occasions (P = 0.3). 3. Ten subjects each performed two identical incremental cycle-ergometer exercise tests on separate occasions during which they were asked to quantify either ‘intensity’ or ‘distress’ by using modified Borg scales. 4. In all subjects there was a significant correlation (P <0.001) between ‘intensity’ and minute ventilation. In eight subjects there was a significant correlation (P <0.05) between ‘distress’ and minute ventilation. One subject displayed no significant correlation and one registered no distress. 5. Mean ‘intensity’ was greater than the mean ‘distress’ (P = 0.0001). The slope of ‘intensity’/minute ventilation was greater than the slope of ‘distress’/minute ventilation (P = 0.0001). 6. Within individuals there was a significant correlation beween ‘intensity’ and ‘distress’ (P <0.05). There was a wide scatter in the slope of this relationship between subjects and maximum ‘intensity’ and ‘distress’ did not correlate. 7. Different elements of the breathlessness sensation could be identified and selectively measured depending on the wording of the instructions given to the subject. 8. There was a wide intersubject variation in the magnitude of both breathlessness ‘intensity’ and ‘distress’ estimates, but the differences between subjects in these two components of the sensation did not appear to follow a common pattern.

Although subjective appetite scores are widely used, studies on the reproducibility of this method are scarce. In the present study nine healthy, normal weight, young men recorded their subjective appetite sensations before and during 5 h after two different test meals A and B. The subjects tested each meal twice and in randomized order. Visual analogue scale (VAS) scores, 10 cm in length, were used to assess hunger, satiety, fullness, prospective food consumption and palatability of the meals. Plasma glucose and lactate concentrations were determined concomitantly. The repeatability was investigated for fasting values, Δ-mean 5 h and mean 5 h values, Δ-peak/nadir and peak/nadir values. Although the profiles of the postprandial responses were similar, the coefficients of repeatability (CR = 2SD) on the mean differences were large, ranging from 2·86 to 5.24 cm for fasting scores, 1·36 to 1·88 cm for mean scores, 2·98 to 5·42 cm for Δ-mean scores, and 3·16 to 6·44 cm for peak and Δ-peak scores. For palatability ratings the CK values varied more, ranging from 2·38 (taste) to 8·70 cm (aftertaste). Part of the difference in satiety ratings could be explained by the differences in palatability ratings. However, the low reproducibility may also be caused by a conditioned satiation or hunger due to the subjects' prior experience of the meals and therefore not just be a reflection of random noise. It is likely, however, that the variation in appetite ratings is due both to methodological day-to-day variation and to biological day-to-day variation in subjective appetite sensations.

Aim There is insufficient evidence to support bony reconstruction of the pubis after a type III internal hemipelvectomy (resection of all or part of the pubis). In this study, we compared surgical complications, postoperative pain, and functional outcome in a series of patients who had undergone a type III internal hemipelvectomy with or without bony reconstruction. Methods In a retrospective cohort study, 32 patients who had undergone a type III hemipelvectomy with or without allograft reconstruction (n = 15 and n = 17, respectively) were reviewed. The mean follow-up was 6.7 years (SD 3.8) for patients in the reconstruction group and 6.1 years (SD 4.0) for patients in the non-reconstruction group. Functional outcome was evaluated using the Musculoskeletal Tumor Society (MSTS) scoring system and the level of postoperative pain with a visual analogue scale (VAS). Results The mean MSTS score of the patients was significantly better in patients after reconstruction (26 (SD 1.7) vs 22.7 (SD 2.0); p < 0.001). The mean visual analogue scale score for pain was significantly less in the reconstruction group (2.1 (SD 2) vs 4.2 (SD 2.2); p = 0.016). One infection occurred in each group. Bladder herniation occurred in three patients (17.6%) in the non-reconstruction group but none in the reconstruction group. Five patients (29.4%) in the non-reconstruction group and one (7%) in the reconstruction group had a limp. Graft displacement occurred in two patients in the reconstruction group. Conclusion We recommend reconstruction of the bony defect after a type III hemipelvectomy: it gives a better functional result, less postoperative pain, and fewer late surgical complications.

OBJECTIVE: To test a reliable and easily administered frustration-induction procedure for experimental research. METHOD: One hundred volunteers (81 women, mean age ± SD 34.2 ± 8 years) physically and psychiatrically healthy submitted to the frustration induction procedure were prevented from reaching reward level scores. Subjective aggressiveness feelings related to frustration were self-rated in a 13-item visual analogue scale before and after the procedure. RESULTS: Significant increases in aggressiveness-related feelings were detected in 12 of the 13 items. This was consistent with the observed overt behavior of the subjects during the task. CONCLUSIONS: The frustration-induction procedure is a simple, easy to administer frustration-induction procedure that can be used in experimental studies in normal subjects.

Anxiety is an unpleasant feeling that is considered a fear of a threatening danger, often the threat is unknown and always includes various emotional and hemodynamic responses experienced by the organism prior to emotional stimulation. To determine the relationship between the degree of pre-operative anxiety with post-operative pain in patients undergoing cesarean sectio with spinal anesthesia techniques at H. Adam Malik Hospital. Descriptive analytic research was conducted at Haji Adam Malik General Hospital in Medan from May to June 2020. The study population was all subjects scheduled to undergo sectio cesarea with spinal anesthesia at Haji Adam Malik General Hospital. The total sample obtained was 28 patients. The normal test of numerical data test was used with the Spearman Correlation test. The research hypothesis was tested using the Mann-Whitney test. In the study conducted on 28 samples divided into 2 groups, it was found that there was a moderate and direct relationship between APAIS scores and VAS scores. Based on this study, it was found that the average preoperative APAIS score was 11.07 (± 3.79). And for the mean value of postoperative VAS is 2.37 (± 1.04). In the result of this study it was found that there was a moderate and unidirectional relationship to the APAIS score and this VAS score (p <0.05). While the preoperative APAIS score was 11.07 (± 3.79). And for the mean postoperative VAS-A value is 3.33 (± 1.03). In the result of this study also found that there is a strong and direct relationship in the APAIS score and this VASA score (p<0.05). There is a moderate and direct relationship between APAIS scores and this VAS score and that there is a strong and direct relationship in the APAIS score and this VAS-A score

The Relationship

1. As marked lability of bronchial obstruction is a risk factor for asthma severity, it may influence dyspnoea, the most common subjective complaint in asthma. We therefore studied the relationship between spontaneous dyspnoea and the degree of bronchial lability, as assessed by the daily variability in peak expiratory flow rate and the bronchial responsiveness to either carbachol or salbutamol, in 33 stable symptomatic asthmatic patients. 2. Three times daily, for 10 consecutive days, the patients rated the intensity of their dyspnoea on a visual analogue scale and immediately afterwards recorded their peak expiratory flow rate. Within the next 5 days, we determined the bronchial response by measuring the forced expiratory volume in 1 s and the specific resistance of airways to either carbachol or salbutamol according to baseline airway obstruction. 3. We characterized dyspnoea for each patient by using two parameters: (1) the relationship with underlying airway obstruction, as assessed by the correlation coefficient r between dyspnoea scores and corresponding values of peak expiratory flow rate (r DSc-PEFR), and (2) the intensity, as assessed by the mean visual analogue scale dyspnoea score adjusted for comparable airway obstruction. Bronchial lability was characterized by (1) variability in mean daily peak expiratory flow rate and (2) bronchial responsiveness to either carbachol (as assessed by the threshold dose and the slope of the dose-response curve) or salbutamol (as assessed by the threshold dose and maximal response). We assessed the relationship between dyspnoea and bronchial lability by correlating each of their respective characteristics. 4. We found large inter-subject differences in both characteristics of dyspnoea, r DSc-PEFR was unrelated to variability in mean daily peak expiratory flow rate and to all characteristics of bronchial responsiveness used, except for maximal salbutamol-induced increase in forced expiratory volume in 1 s (as a percentage of predicted). Adjusted visual analogue scale dyspnoea scores were unrelated to all characteristics of bronchial lability. 5. Our results suggest that spontaneous dyspnoea, as characterized by its intensity at comparable levels of airway obstruction and by its relationship with underlying airway obstruction, is poorly related to the degree of bronchial lability in stable symptomatic asthmatic patients.
