To determine the minimum duration of exercise for improving the aerobic capacity of patients with coronary heart disease (CHD), 23 female patients with CHD and/or hypertension, aged 52.8±8.7 years, were studied. After pre-testing, all the patients were conditioned for 4 months in order to elicit improvements in their aerobic capacity and other healthrelated factors. Duration and contents of daily activities were recorded by each patient. After 4 months, oxygen uptake at lactate threshold (VO2LT) and VO2peak were increased significantly from 12.9±2.6 to 16.0±3.4ml/kg/min and from 18.5±4.2 to 22.3±5.6ml/kg/min, respectively. Duration of exercise conditioning for the 4 months averaged 23.8±12.2min per day, ranging from 4.6 to 49.7min. Correlational analyses were applied in order to determine the extent to which the improvement in aerobic capacity was associated with the individual mean duration of exercise conditioning. As a result, changes in VO2LT and VO2peak correlated significantly with the exercise duration (Pearson's r=0.51, Spearman's rho=0.47 for VO2LT; Spearman's rho=0.58 for VO2peak) . Both VO2LT and VO2peak tended to improve markedly when daliy exercise duration was 20 min or longer. Furthermore, it was shown that the improvement in aerobic capacity remained almost the same within a range of exercise duration of 20 to 60min. We suggest that the minimum exercise duration for improving the aerobic capacity of cardiac patients is 20 to 30min per day or 140min or more per week.

To estimate how much physical activity is needed to improve overall health status in female patients with ischemic heart disease (IHD), the dose-response relationship between the duration of daily aerobic exercise and change in vital age (VA) was assessed for 4 months of exercise training. VA was considered as an index of physical health status and was computed from various coronary risk facotrs and physical fitness elements. Eighteen female patients with IHD, aged 54.3±9.1 yrs, continued the supervised exercise training 1-2 d/wk and the self-controlled exercise training 1-5 d/wk for 4 months. The intensity of exercise was set at individually determined lactate threshold. Daily duration of aerobic type exercise calculated for each patient averaged 21.1±11.0min/d, rang ing from 4.6 to 46.7 min/d. After the 4-month exercise training, VA decreased from 59.6±12.1 yrs to 54.2±11.8 yrs (P<0.05) . Significant correlation was found between daily duration of exercise and the change in VA (Spearman's rho=-0.60 ; Pearson's r=-0.62) . In this relationship, 10 min/d of exercise induced the decrease in VA and no further decrease in VA was found over the 30 min/d of exercise. In the 11 variables which constitute the equation of VA, oxygen uptake at lactate threshold (Spearman's rho=0.65; Pearson's r=0.64) and balancing on one leg with eyes closed (Spearman's rho=0.48; Pearson's r=0.51) significantly correlated with daily duration of aerobic exercise. From these results, it is suggested that the amount of moderate intensity exercise required to improve physical health status in female patients with IHD may be 10-30 minutes per day.

[Objective]To analyze the situation of clinics that want to employ acupuncturists and masseurs and to obtain basic data to find employment in the clinic in the future.
[Methods]The subjects were 52 clinics that responded to the questionnaire survey saying they wanted to employ acupuncture and massage therapists. They were divided into three groups according to the license (acupuncture group (n = 5), acupuncture &massage group (n = 25), massage group (n = 22)). The situation and the business realities of the clinic were analyzed.
[Results]Clinics with obstetrics and gynecology want to employ only acupuncturists. There were as many employment needs for both acupuncturists and masseurs in clinics with orthopedics and rehabilitation. The employment satisfaction rating is higher for the patient's need standpoint than cost-effectiveness.
[Conclusion]We analyzed the status of clinics that want to employ acupuncturists and masseurs. This study is expected to help promote the employment of medical acupuncturists and masseurs.

This study investigated whether significant coronary artery stenosis in 231 consecutive unstable angina patients can be diagnosed by thoroughgoing history-taking initial electorocardiography and symptom- or sign-limited treadmill exercise ECG after medication. The unstable angina patients were divided into those with accelerated angina, those with new-onset effort angina and those with angina at rest based on the findings of detailed inquiry. Initial ECG showed that the sensitivity and specificity of detecting significant coronary artery stenosis in all patients were 55.2% and 63.2%, respectively. In accelerated angina, sensitivity and specificity were 52.2% and 50.0%, respectively. In new-onset effort angina, sensitivity and specificity were 46.7% and 57.1%, respectively. In angina at rest, sensitivity and specificity were 69.0% and 68.3%, respectively. Initial ECG provided valuable diagnostic information about angina at rest. Treadmill exercise ECG offered 66.0% sensitivity and 89.2% specificity in all patients, respectively. In accelerated angina, sensitivity and specificity were 80.0% and 66.7%, respectively. In new-onset effort angina, sensitivity and specificity were 70.8% and 87.8%, respectively. In angina at rest, sensitivity and specificity were 48.3% and 91.4%, respectively. Thus, treadmill exercise electrocardiograms provided valuable diagnostic information in the case of unstable angina, especially accelerated angina and new-onset effort angina. For patients with angina at rest, this testing was very useful for excluding significant coronary artery stenosis.
In conclusion, detailed inquiry, initial ECG and symptom- or sign-limited treadmill exercise ECG after medical stabilization proved to be of great value for diagnosing unstable angina patients with significant coronary artery stenosis.

Biological age based on the assessment of various physiological factors measured in a resting state has been proposed as an appropriate index of aging. We have recently developed an equation for estimation of physical fitness age (PFA), which is composed of eight age-related physical fitness variables. These include oxygen uptake corresponding to lactate threshold (Vo2@LT), maximal oxygen uptake (Vo2max), side step, grip strength, vertical jump, foot balance with eyes closed, trunk extension, and trunk flexion. In this study, the validity of PFA as a critical index of physical health and/or aging status was investigated from a longitudinal standpoint on the assumption that exercise habituation does contribute to health promotion. The subjects were 14 Japanese middle-aged and elderly men, aged 50 to 70 years, all of whom were patients with coronary heart disease (CHD) . The subjects participated in a supervised exercise conditioning program for 90 to 120 min each session, 2 times weekly for 4 months. Analyses of the data indicated that the mean PFA of the subjects (66.0±9.0 yr) after conditioning was significantly (P<0.05) lower than the mean PFA (72.8±8.6 yr) obtained before conditioning. After the exercise program, significant increases were documented in Vo2@LT (17%), Vo2max (12%), side step (26%), trunk flexion (109%), trunk extension (7%), vertical jump (12%), and foot balance with eyes closed (31%) . Therefore, we conclude that our exercise conditioning program may alter the overall physical fitness of patients with CHD, and that PFA could be a valid physical health and/or aging index.

PURPOSE: To investigate the efficacy of tazobactam/piperacillin (TAZ/PIPC) plus levofloxacin (LVFX) as a prophylactic administration in transrectal prostate biopsy (TPBX). MATERIALS AND METHODS: We investigated 201 consecutive patients who underwent TPBX in one Japanese hospital during the period of 2009-2010. The patients received TAZ/PIPC 4.5 g i.v. once just before and 3 hours after TPBX, plus oral LVFX 300 mg or 500 mg daily for 3 days. We examined the infectious adverse events and laboratory data (serum white blood cell [WBC] count and C-reactive protein [CRP]) before and 1 day after TPBX. RESULTS: Only one patient (0.50%) in 201 cases had febrile complications after TPBX. Serum WBC and CRP did not rise significantly on the day after TPBX compared with before TPBX (p>0.05). There was no significant difference in the rise of serum WBC and CRP before and after TPBX in the comparison of LVFX 500 mg with LVFX 300 mg in the TAZ/PIPC plus LVFX regimen. CONCLUSIONS: TAZ/PIPC plus LVFX can be considered as a prophylactic regimen for preventing infectious complications in TPBX.

PURPOSE: The purpose of this study was to evaluate whether neo-adjuvant hormonal therapy (NHT) prior to radical retropubic prostatectomy (RRP) for prostate cancer (PCa) is beneficial in terms of surgical outcomes and for preventing or delaying biochemical recurrence via single-surgeon case series study. MATERIALS AND METHODS: Fifty-three men underwent RRP by a single surgeon. The patients were divided into two groups according to whether or not NHT was performed prior to RRP. The study was analyzed retrospectively. We evaluated clinical parameters, surgical parameters, and biochemical recurrence rate. Group 1 (n=34) was treated with RRP only, while Group 2 (n=19) underwent RRP along with NHT. RESULTS: There were no significant differences in clinical, operation-related and pathological factors between the two groups (p>0.05). There was also no significant difference in biochemical recurrence rate between the two groups at the last follow-up, although Group 2 tended to have a lower PCa recurrence rate than Group 1 and the initial prostate-specific antigen (PSA) level was significantly higher in Group 2 than Group 1 (p=0.0496). CONCLUSION: The present single-surgeon case series study revealed a trend toward a lower rate of PCa recurrence in NHT+RRP treated patients compared to those treated with RRP alone, but this did not reach statistical significance, despite the fact that NHT+RRP patients exhibited higher serum PSA levels preoperatively. Prospective studies with a longer duration of observation and a greater number of patients would be helpful in evaluating NHT more definitively.

PURPOSE: The objective of this study was to retrospectively investigate postoperative infectious complications (PICs) in our early experience with holmium laser enucleation of the prostate (HoLEP) followed by mechanical morcellation for symptomatic benign prostatic hyperplasia. MATERIALS AND METHODS: A retrospective review was performed of the clinical data for 90 consecutive patients who underwent HoLEP at our institution between February 2008 and March 2011. All patients were evaluated for the emergence of PICs, including prophylactic antibiotic administration (PAA) and the influence of the kind or duration of PAA on PIC. The details of cases with PICs were also examined. RESULTS: The patients' mean age was 71 years (range, 50 to 95 years), and their mean prostate volume was 60 mL (range, 2 to 250 mL). There were 7 cases (7.78%) with PICs; in detail, 3 patients were diagnosed with prostatitis, 2 with pyelonephritis, and 2 with epididymitis. Three patients had positive urine cultures: 1 had Serratia marcescens/Proteus mirabilis, 1 had S. marcescens, and 1 had Klebsiella pneumonia; only one case had urological sepsis. Our statistical data showed no significant differences between 2 or fewer days and 3 or more days of PAA and PIC occurrence. There was also no significant effect on PIC occurrence of sulbactam/ampicillin compared with other antibiotics. CONCLUSIONS: The results of this retrospective study showed that PIC occurrence did not depend on the duration or the kind of PAA. Further prospective study is necessary for the evaluation and establishment of prophylactic measures for PICs.

PURPOSE: To evaluate the efficacy of using 3-tesla (T) magnetic resonance imaging (MRI) diagnosis of extracapsular extension (ECE) for decision-making about neurovascular bundle (NVB) preservation in robot-assisted radical prostatectomy (RARP) for prostate cancer (PC). MATERIALS AND METHODS: We prospectively collected data on PC patients (n=67) who underwent preoperative 3-T MRI before RARP. The choice between nerve sparing or resection was based on 3-T MRI findings of ECE. We compared the MRI findings with the pathological data on surgical margins. Our clinical staging in this study was defined only by MRI. RESULTS: When the data were divided by prostate lobe (right lobe or left lobe, n=134), 3-T MRI showed 28 positive cases of ECE in 134 prostate lobes, allowing NVB preservation in 42 cases (31.3%). Nerve-sparing surgery was achieved in 38.7% of cases in which clinical T2 staging by MRI was reported. The pathological data revealed that 10 of 134 prostate lobes had positive ECE. The overall sensitivity, specificity, positive predictive value, and negative predictive value for predicting stage T3 (positive ECE) by side were 60.0% (12 of 20 sides), 86.0% (98 of 114 sides), 42.9% (12 of 28 sides), and 92.5% (98 of 106 sides), respectively. CONCLUSIONS: Three-T MRI prior to RARP enables the use of ECE diagnosis to guide decision-making about NVB preservation, with comparatively high specificity and negative predictive value. Further prospective studies are underway to reach more definitive conclusions.

PURPOSE: To detect predictive factors for postoperative incontinence following holmium laser enucleation of the prostate (HoLEP) according to surgeon experience (beginner or experienced) and preoperative clinical data. METHODS: Of 224 patients, a total of 203 with available data on incontinence were investigated. The potential predictive factors for post-HoLEP incontinence included clinical factors, such as patient age, and preoperative urodynamic study results, including detrusor overactivity (DO). We also classified the surgeons performing the procedure according to their HoLEP experience: beginner (<21 cases) and experienced (≥21 cases). RESULTS: Our statistical data showed DO was a significant predictive factor at the super-short period (the next day of catheter removal: odds ratio [OR], 3.375; P=0.000). Additionally, patient age, surgeon mentorship (inverse correlation), and prostate volume were significant predictive factors at the 1-month interval after HoLEP (OR, 1.072; P=0.004; OR, 0.251; P=0.002; and OR, 1.008; P=0.049, respectively). With regards to surgeon experience, DO and preoperative International Prostate Symptom Score (inverse) at the super-short period, and patient age and mentorship (inverse correlation) at the 1-month interval after HoLEP (OR, 3.952; P=0.002; OR, 1.084; P=0.015; and OR,1.084; P=0.015; OR, 0.358; P=0.003, respectively) were significant predictive factors for beginners, and first desire to void (FDV) at 1 month after HoLEP (OR, 1.009; P=0.012) was a significant predictive factor for experienced surgeons in multivariate analysis. CONCLUSIONS: Preoperative DO, IPSS, patient age, and surgeon mentorship were significant predictive factors of postoperative patient incontinence for beginner surgeons, while FDV was a significant predictive factors for experienced surgeons. These findings should be taken into account by surgeons performing HoLEP to maximize the patient's quality of life with regards to urinary continence.
