Background: Farinelli breathing (FB) exercise is a typical breathing exercise used by singers. This study aimed to compare effects of FB exercise and diaphragmatic breathing (DB) exercise on respiratory function and symptoms in patients with chronic obstructive pulmonary disease (COPD). Methods: Sixteen patients aged 51-80 years with mild or moderate COPD were recruited for this study. They were divided into two groups: DB group (n=8) and FB group (n=8). Both groups received complete breathing exercise training five times per week for 8 weeks. Their respiratory functions, COPD symptoms, cytokine levels, and oxidative stress variables were analyzed during pre- and post-tests. Dependent variables were compared between pre- and post-tests using paired t-tests. An independent t-test was used to compare variables between the groups. Differences were considered significant at p<0.05. Results: The maximal expiratory pressure (MEP), maximum oxygen consumption (VO₂max), and COPD Assessment Test (CAT) scores changed significantly in the DB group after the 8-week intervention compared to those at pre-test, whereas force vital capacity, forced expiratory volume in the first second, maximum voluntary ventilation, maximal inspiratory pressure (MIP), MEP, VO₂max, CAT score, tumor necrosis factor-α, and malondialdehyde level changed significantly in the FB group at post-test compared to those at pre-test. Moreover, both MIP and MEP in the FB group were significantly higher than those in the DB group. Conclusion: FB exercise improved respiratory functions and COPD symptoms of patients with COPD. It might be an alternative breathing exercise in pulmonary rehabilitation programs for patients with COPD.

본 연구는 횡격막에 적용된 테이핑 처치가 30초간의 무산소 운동수행력에 미치는 영향을 알아보고자 실시하였다. 건강한 대학생 18명을 대상으로 실험군(KT)과 대조군(Sham)에 각각 9명씩 무작위 할당되었다. 두 그룹 모두 윙게이트 검사 기반의 사전 측정이 이루어지고 1주일 휴식 후 처치와 함께 사후 측정이 실시되었다. 두 집단간 변인들의 통계는 사전, 사후값의 변화율을 Mann-Whitney U검정으로 실시하였고, 그 결과 대조군의 평균 파워(AP)에서만 통계적으로 유의한 차이가 나타났다. 이는 횡격막 테이핑이 30초 동안의 무산소 운동 수행에 영향을 미치지 않았음을 의미한다. 하지만 30초보다 긴 장기간 무산소 운동에서 유산소 대사가 증가함을 고려할 때 이후 다양한 시간 범위 내 무산소 운동 수행에 대한 추가 연구가 필요할 것으로 생각된다.

Purpose : In this study, rectus abdominis relaxation intervention was administered to office workers who were experiencing low back pain due to sitting for extended periods of time in an incorrect posture. This study aimed to develop an effective treatment program for individuals who experience low back pain. This was done by verifying changes using the Korean Oswestry Disability Index (K-ODI) and considering kyphosis. Both factors are related to low back pain. Methods : This study included 39 office workers with low back pain. The participants were randomly assigned to three groups. 1) The functional massage and self-stretching (FAS) group (n=14). 2) The diaphragmatic breathing and self-stretching (DAS) group (n=13). 3) The self-stretching (S) group (n=12). All groups applied the intervention for 30 minutes a day, thrice a week for four weeks. All participants were evaluated using the K-ODI and thoracic kyphosis measurements before and after the intervention. Results : The findings of this study are as follows. All three groups had improved K-ODI scores after the intervention. The FAS and DAS groups showed a greater effect than the S group. However, there was no difference in effect between the FAS and DAS groups. Kyphosis was not improved in any of groups after the intervention, and there was no difference between the three groups. Conclusion : This study showed that the FAS, DAS, and S programs were effective relaxation interventions that improved the K-ODI for office workers with low back pain. The FAS and DAS programs were more effective than the S program. Therefore, it is recommended to combine relaxation and stretching of the rectus abdominis muscle for office workers who experience low back pain. Clinically, a relaxation intervention that is most appropriate for the patient, depending on his or her condition, should be.

Objective: To construct a CT-based Fagotti scoring system by analyzing the correlations between laparoscopic findings and CT features in patients with advanced ovarian cancer. Materials and Methods: This retrospective cohort study included patients diagnosed with stage III/IV ovarian cancer who underwent diagnostic laparoscopy and debulking surgery between January 2010 and June 2018. Two radiologists independently reviewed preoperative CT scans and assessed ten CT features known as predictors of suboptimal cytoreduction. Correlation analysis between ten CT features and seven laparoscopic parameters based on the Fagotti scoring system was performed using Spearman's correlation. Variable selection and model construction were performed by logistic regression with the least absolute shrinkage and selection operator method using a predictive index value (PIV) ≥ 8 as an indicator of suboptimal cytoreduction. The final CT-based scoring system was internally validated using 5-fold cross-validation. Results: A total of 157 patients (median age, 56 years; range, 27-79 years) were evaluated. Among 120 (76.4%) patients with a PIV ≥ 8, 105 patients received neoadjuvant chemotherapy followed by interval debulking surgery, and the optimal cytoreduction rate was 90.5% (95 of 105). Among 37 (23.6%) patients with PIV < 8, 29 patients underwent primary debulking surgery, and the optimal cytoreduction rate was 93.1% (27 of 29). CT features showing significant correlations with PIV ≥ 8 were mesenteric involvement, gastro-transverse mesocolon-splenic space involvement, diaphragmatic involvement, and para-aortic lymphadenopathy. The area under the receiver operating curve of the final model for prediction of PIV ≥ 8 was 0.72 (95% confidence interval: 0.62-0.82). Conclusion: Central tumor burden and upper abdominal spread features on preoperative CT were identified as distinct predictive factors for high PIV on diagnostic laparoscopy. The CT-based PIV prediction model might be useful for patient stratification before cytoreduction surgery for advanced ovarian cancer.

Background Abdominoplasty with abdominal plication increases intra-abdominal pressure (IAP) and has been previously associated with limited diaphragmatic excursion and respiratory dysfunctions. Many factors found in abdominoplasties and among postbariatric patients predispose them to a higher occurrence. This study aims to evaluate the impact of abdominal plication among postbariatric patients, assess whether the plication increases their IAP, and analyze how these IAP correlate to their postoperative outcome. Methods This prospective study was performed on all patients who underwent circumferential Fleur-De-Lis abdominoplasty. For this intended study, the IAP was measured by an intravesical minimally invasive approach in three stages: after the initiation of general anesthesia, after a 10-cm abdominal wall plication and skin closure, and 24 hours after the procedure. Results We included 46 patients, of which 41 were female and 5 were male. Before the bariatric procedure, these patients had an average maximum weight of 121.4 kg and an average maximum body mass index of 45.78 kg/m²; 7 were grade I obese patients, 10 were grade II, and 29 were grade III. Only three patients were operated on with a gastric sleeve and 43 with gastric bypass. We presented six patients with transitory intra-abdominal hypertension in the first 24 hours, all of them from the grade I obesity group, the highest presented was 14.3 mm Hg. We presented 15% (7/46) of complication rates, which were only four seroma and five dehiscence; two patients presented both seroma and wound dehiscence. Conclusion Performing a 10-cm abdominal wall plication or greater represents a higher risk for intra-abdominal hypertension, slower general recovery, and possibly higher complication rate in patients who presented a lower degree of obesity (grade I) at the moment of the bariatric surgery.

One aim of this study was to find out the difference of indirect blood pressure between the types of instruments. The difference of indirect blood pressure was measured with mercury sphygomomanometer and electronic blood pressuremeter. Another was to determine the difference of indirect blood pressure according to width of cuff and site of cuff. Indirect blood pressures were measured with the diaphragmatic side of sphygomomanometer. The subjects were 40 female volunteers, whose arm circumferences were from 22 to 34cm. The data were analyzed by SPSS-PC program and pared t-test was used. The results are summarized as follows ; 1. Mercury sphygomomanometer systolic pressure was higher(average 2.20mmhg) than electronic blood pressuremeter. It was statistically significant(p=0.026). 2. The value of Mercury sphygomomanometer diastolic pressure was lower(2.00mmhg) than electronic's. It was statistically significant(p=0.03) 3. In the mercury sphygomomanometer systolic pressure, the value of standard cuff($12{\times}23cm$) was higher(2.40mmhg) than large one's($14{\times}45cm$). It was statistically significant(p=0.007). 4. In diastolic pressure(K4), the value of standard cuff was higher(0.65mmhg) than large cuff's. It was not statistically significant(p=0.481). In K5, the value of standard cuff($12{\times}23cm$) was higher(0.55mmhg) than large cuff's. It was not statistically significant(p=0.541). 5. Difference according to site of showed that the values of systolic pressure over elbow joint were higher(20.00mmhg, 26.45mmhg) than ones at site of elbow joint. It was significant statistically(p=0.000) and clinically. 6. The values of diastolic pressure(K4) over elbow joint were higher(17.10mmhg, 21.60mmhg) than ones at site of elbow joint. It was significant statistically (p=0.000) and clinically. The values of K5 over elbow joint were higher(17.25mmhg, 22.15mmhg) than ones at site of elbow joint. It was significant statistically(p=0.000) and clinically. I think similar studies about indirect blood pressure according to diseases and positions are necessary. In addition, similar studies, are required about accuracy of method electronic blood pressuremeter according to site of mesurement.

The distribution of portal veins within the liver in 30 Korean native cattle were observed. Vinylite solution was injected into portal veins of eighteen specimens for cast preparation. The angiography was prepared in twelve specimens by injecting 30% barium sulfate solution into portal veins, and then radiographed on a X-ray apparatus(Shimadzu 800MA 120Kvp). The results were summarized as follow: 1. The Vena portae was divided immediately upon entering the liver into a very short Truncus dexter venae portae($14.75{\pm}4.86$ : 6.9~23.1mm) and a long Truncus sinister venae portae($94.16{\pm}9.62$ : 110~150mm). 2. The Truncus sinister venae portae runs of first in the long axis of the liver from the Porta hepatis toward the left lobe. At the boundary between the quadrate and left lobes it bends sharply 50 to 80 degrees toward the Incisura ligamentum teretis, and after a course of 36. 5 to 54.mm between the quadrate and left lobes, ends abruptly. The Truncus sinister venae portae is divided for description into the Pars transversa, from the Porta hepatis to the flexure, and the Pars umbilicalis, from the flexure to the end. 3. The branches of Venae portae were Ramus ventralis lobi sinistri, Ramus intermedius lobi sinistri, Ramus dorsalis lobi sinistri, Ramus lobi quadratii, Ramus ventralis lobi dextri, Ramus intermedius lobi dextri, Ramus dorsalis lobi dextri, Rami processus caudatorum and Rami processus papillarum. 4. The Ramus intermedius lobi sinistri was arised from the left surface of the Pars umbilicalis, and was origined on the common trunk with Ramus dorsalis lobi sinistri(3 cases, 10%) or Ramus ventralis lobi sinistri(3 cases, 10%). 5. The Rami lobi quadratii consisted of the vein(15 cases, 50%) or two veins(15 cases, 50%), and was observed on the arched-shaped at 2 cases (6.6%) of the liver. 6. The Rami processus caudatorum consisted of one vein(28 cases, 93.3%) or two veins(2 cases, 6.6%). The former were formed common trunk with R, dorsalis lobi dextri(7 cases, 23.3%) or R. ventralis lobi dextri (2 cases, 6.6%). 7. The Rami processus papillarum were arised from the dorsal border of Pars transversa, and also gave off many small branches supplied papillary process of the caudate lobe. 8. The anastomosis on the branches of Vena portae was observed in the intralobar and interlobar areas. 9. The Truncus dexter venae portae and Truncus sinister venae were ramified many secondary branches that were radiated within the liver. 10. On the diaphragmatic surface, small vessels of the portal veins were observed, while there were big ones on the visceral surface. 11. The ramified angles at Ramus dorsalis lobi dextri, Rami processus papillarum, Ramus dorsalis lobi sinistri, Ramus intermedius lobi sinistri, Ramus ventralis lobi sinistri, Rami lobi quadratii, Rami processus caudatorum, Ramus ventralis lobi dextri and Ramus intermedius were 10~50, 70~110, 100~150, 140~170, 185~220, 270~330, 240~300, 270~320 and 340~10 degrees, respectively.
