  • Biomedical signal measurement technology using images has been developed, and researches on respiration signal measurement technology for maintaining life have been continuously carried out. The existing technology measured respiratory signals through a thermal imaging camera that measures heat emitted from a person's body. In addition, research was conducted to measure respiration rate by analyzing human chest movement in real time. However, the image processing using the infrared thermal image may be difficult to detect the respiratory organ due to the external environmental factors (temperature change, noise, etc.), and thus the accuracy of the measurement of the respiration rate is low.In this study, the images were acquired using visible light and infrared thermal camera to enhance the area of the respiratory tract. Then, based on the two images, features of the respiratory tract region are extracted through processes such as face recognition and image matching. The pattern of the respiratory signal is classified through the k-nearest neighbor classifier, which is one of the statistical classification methods. The respiration rate was calculated according to the characteristics of the classified patterns and the possibility of breathing rate measurement was verified by analyzing the measured respiration rate with the actual respiration rate.

  • Aims and Background: To evaluate the efficacy of a combination of aprepitant and conventional antiemetic therapy in patients with advanced or recurrent lung cancer receiving moderately emetogenic chemotherapy (MEC). Methods: Patients with advanced or recurrent lung cancer who were treated with MEC regimens at the Department of Respiratory Medicine, Fukuoka University Hospital, were included and classified into the following groups: control group (treatment: 5-HT3 receptor antagonists + dexamethasone) and aprepitant group (treatment: 5-HT3 receptor antagonists + dexamethasone + aprepitant). The presence or absence of chemotherapy-induced nausea and vomiting (CINV) was evaluated according to the Common Terminology Criteria for Adverse Events (CTCAE) v4.0; patients with grade 1 or above were considered positive for CINV. Food intake per day, completion of planned chemotherapy, and progression-free survival (PFS) achieved by chemotherapy were investigated. Results: The complete suppression rate of nausea in the aprepitant group was significantly higher than that in the control group (p = 0.0043). Throughout the study, the food intake in the aprepitant group was greater than that in the control group, with the rate being significantly higher, in particular, on day 5 (p = 0.003). The completion rate of planned chemotherapy was also higher in the aprepitant group (p = 0.042). PFS did not differ significantly, but tended to be improved in the aprepitant group. Conclusions: The aprepitant group showed significantly higher complete suppression of nausea, food intake on day 5, and completion of planned chemotherapy than the control group.

  • Vaccination in adults is recommended according to the age group and underlying diseases or risks of exposure. Patients with chronic diseases including chronic obstructive pulmonary diseases are susceptible to infectious diseases and related serious complications. They need risk-related vaccination along with age-related vaccination. Both influenza and pneumococcal vaccination are recommended in patients with chronic obstructive pulmonary diseases. They are additive if administered simultaneously. Pertussis vaccination is also needed in adolescents and adults. Although there is strong need for these vaccinations, the actual vaccination rate is low. Measures to effectively enhance the vaccination rate are needed.

  • PURPOSE: This study examined the effects of an eight weeks twenty meters walk on the cardiorespiratory fitness and strength of the shoulder extensor, hip extensor, and dorsiflexor of stroke survivor outpatients in two tertiary hospitals in Osogbo, Nigeria. METHODS: A purposive sampling technique was used to select 21 registered right or left outpatient hemiplegic stroke survivors in a pre- and post-test experimental research design. The research questions were presented using the descriptive statistics of frequency, percentage, mean, and standard deviation. The differences between the mean of the cardio-respiratory indices and the muscle strength were tested by repeated measures analysis of variance followed by Bonferroni post-hoc test for multiple comparisons. RESULTS: No significant differences in heart rate were observed at week 0 compared to week 4. A significant decrease was recorded in the parameter at week 8, compared to week 4. Moreover, there were significant decreases in blood pressure and respiratory rate in week 0, compared to week 4, and in the respiratory rate, compared to week 8. In contrast, significant elevations in VO2 max were observed in week 0, compared to week 4, and in the week 4, compared to week 8. Furthermore, significant elevations in muscular strength were documented when comparisons were made at weeks 0, 4, and 8. CONCLUSION: Eight weeks of twenty meters walk aerobic exercise improve the cardio-respiratory fitness and muscular strength of stroke survivor outpatients.

  • 1. The effect of variations in inspiration and expiration times on heart rate variability was studied in 78 healthy subjects (mean age $24.35{\pm}1.92$ years; 47 male) between regulated respiration group and normal respiration group as the control group. 2. The control group followed normal respiration pattern, whereas the regulated group followed three types of respiration pattern. The first pattern was long respiration(E/I ratio 1.6:1), the second pattern was short inspiration followed by long expiration (SILE), and the last pattern was long inspiration followed by short expiration(LISE). The average expiration/inspiration time ratios of SILE and LISE were 1.0 and 3.4, respectively. The respiration rate in the regulated group was approximately 10 cycles/min. 3. Respiration rate and tidal volume are respiratory variables known to modulate RSA. The results of the present study indicate that RSA can also be modulated by a third respiratory variable, the expiration/inspiratory time ratio. In this study, LF, HF, RSA, VLF is increased the most in LISE group compared to the other groups. HF and RSA increased significantly in the long respiration rate and SILE groups. However LF and VLF, which reflects the sympathetic tones, did not increase as much as the LISE group.
