Assessment of the albumin-bilirubin grade as a prognostic factor in patients with non-small-cell lung cancer receiving anti-PD-1-based therapy.

INTRODUCTION: The albumin-bilirubin (ALBI) grade is a novel indicator of the liver function. Some studies showed that the ALBI grade was a prognostic and predictive biomarker for the efficacy of chemotherapy in cancer patients. The association between the ALBI grade and outcomes in patients with non-small-cell lung cancer (NSCLC) treated with cancer immunotherapy, however, is poorly understood. METHODS: We retrospectively enrolled 452 patients with advanced or recurrent NSCLC who received anti-programmed cell death protein 1 (PD-1)-based therapy between 2016 and 2019 at three medical centers in Japan. The ALBI score was calculated from albumin and bilirubin measured at the time of treatment initiation and was stratified into three categories, ALBI grade 1-3, with reference to previous reports. We examined the clinical impact of the ALBI grade on the outcomes of NSCLC patients receiving anti-PD-1-based therapy using Kaplan-Meier survival curve analysis with log-rank test and Cox proportional hazards regression analysis. RESULTS: The classifications of the 452 patients were as follows: grade 1, n = 158 (35.0%); grade 2, n = 271 (60.0%); and grade 3, n = 23 (5.0%). Kaplan-Meier survival curve analysis showed that the ALBI grade was significantly associated with progression-free survival and overall survival. Moreover, Cox regression analysis revealed that the ALBI grade was an independent prognostic factor for progression-free survival and overall survival. CONCLUSION: The ALBI grade was an independent prognostic factor for survival in patients with advanced or recurrent NSCLC who receive anti-PD-1-based therapy. These findings should be validated in a prospective study with a larger sample size.

Cost effectiveness of romosozumab versus teriparatide for severe postmenopausal osteoporosis in Japan.

This study assessed the cost effectiveness of romosozumab versus teriparatide, both sequenced to alendronate, for the treatment of severe postmenopausal osteoporosis in Japan, using bone mineral density (BMD) efficacy data. Results show that romosozumab/alendronate produces greater health benefits at a lower cost than teriparatide/alendronate. INTRODUCTION: This study aims to assess the cost effectiveness of romosozumab versus teriparatide, both sequenced to alendronate, for the treatment of severe postmenopausal osteoporosis in Japanese women previously treated with bisphosphonates. METHODS: A Markov model was used to assess the relative cost effectiveness of 1 year of romosozumab versus 2 years of teriparatide, both sequenced to alendronate for a total treatment duration of 5 years. Outcomes for a cohort of women with a mean age of 78 years, a T-score ≤-2.5 and a previous fragility fracture were simulated over a lifetime horizon. The analysis was conducted from the perspective of the Japanese healthcare system and used a discount rate of 2% per annum. To inform relative fracture incidence, the bone mineral density (BMD) advantage of romosozumab over teriparatide was translated into relative risks of fracture, using relationships provided by a meta-regression of osteoporosis therapy trials. Outcomes were assessed in terms of lifetime costs (2020 US dollars) and quality-adjusted life years (QALYs). RESULTS: Base case results showed that, compared with teriparatide/alendronate, romosozumab/alendronate reduced costs by $5134 per patient and yielded 0.045 additional QALYs. Scenario analyses and probabilistic sensitivity analysis confirmed that results are robust to uncertainty in model assumptions and inputs. CONCLUSION: Results show that romosozumab/alendronate produces greater health benefits at a lower total cost than teriparatide/alendronate.

Perinatal smoking exposure and risk of asthma in the first three years of life: A prospective prebirth cohort study.

BACKGROUND: There is limited evidence on the association between prenatal smoking exposure and the risk of asthma in children. The aim of this prebirth cohort study was to investigate the association between prenatal and postnatal tobacco smoke exposure and the risk of asthma in Japanese children. METHODS: Study subjects were 1304 mother-child pairs. Information on the variables under study was obtained using repeated questionnaires that were completed by mothers, first prior to delivery, then shortly after birth and subsequently around 4, 12, 24, and 36 months after delivery. Ever asthma was defined as a maternal report of physician-diagnosed asthma at any time since birth. Current asthma was defined as the use of asthma medication at the time of the sixth survey. RESULTS: Logistic regression models revealed that maternal active smoking, either before pregnancy or during pregnancy, was not associated with the risk of ever asthma or current asthma. Further, no association was observed between postnatally living with at least one household smoker and the risk of asthma. Among children whose mothers are never smokers, maternal second-hand smoke (SHS) exposure at work and/or at home during pregnancy increased the risk of ever asthma and current asthma in children; adjusted odds ratio (95% confidence intervals) for ever asthma and current asthma were 2.41 (1.13-5.05) and 4.82 (1.68-13.43), respectively. CONCLUSIONS: Our findings suggest that maternal SHS exposure during pregnancy might be associated with an increased risk of ever asthma and current asthma in young children whose mothers have never smoked.

Cost utility analysis of pharmacist counseling care for breast cancer chemotherapy outpatients.

Chemotherapy for cancer is increasingly implemented in the outpatient setting. Pharmacists contribute to cancer treatment by conducting counseling during outpatient chemotherapy visits. They provide guidance on drug treatment, side effects, and side effect countermeasures on every visit. However, there have been few economic evaluations of pharmacist involvement in outpatient chemotherapy. Therefore, we performed a cost utility analysis. We assigned usual care (control) and pharmacist counseling to two groups of 19 patients receiving outpatient chemotherapy for breast cancer at Gifu Municipal hospital. Quality of life was measured at three timepoints before and during chemotherapy treatment using the EuroQol 5 dimension instrument (EQ-5D). EQ-5D values across the timepoints were 0.831, 0.757, and 0.791 for the control group, and 0.882, 0.883, and 0.921 for the pharmacist counseling group. The additional cost in the pharmacist counseling group was 2,227 yen per counseling session. The change in quality-adjusted life years (QALY) was a maximum of -0.021±0.186 in the control group and 0.007±0.199 in the pharmacist counseling group. The maximum cost for one QALY was 1,360,558 yen (≈12,460 US dollars). Pharmacists' counseling in outpatient cancer chemotherapy for breast cancer patients had an acceptable incremental cost-effect ratio, contributing to improved patient quality of life without significant additional expenditure to healthcare.

Development of the Nutrition and Functionality Assessment (NFA) among Older Adults in Japan.

OBJECTIVE: Develop and evaluate the feasibility and validity of the Nutrition and Functionality Assessment (NFA) which identifies "target" older adults who could benefit from a personalized program following evaluation of their nutrition status and physical functionality. DESIGN: Cross-sectional study. SETTING: Community and geriatric day-care centers and university in Japan. PARTICIPANTS: 267 older adults aged 65-90. MEASUREMENTS: The "target" individuals were screened based on gait speed (0.6-1.5 m/s). Nutrition (Mini Nutrition Assessment-short form and protein intake), strength (30s chair sit-to-stand and hand-grip strength) and endurance (6-minute walk) were assessed. Physical activity was monitored using a tri-axil accelerometer for a week. Fried frailty phenotype was also assessed. RESULTS: Out of 267 individuals, 185 (69%) had gait speed between 0.6-1.5 m/s, corresponding to our "target" group from which, 184 (95%) completed the nutrition and physical functionality assessments with the physical activity monitoring. The NFA was completed in approximately 30 minutes. No adverse events directly due to the NFA were reported. NFA physical functionality and global scores were significantly related to frailty phenotype but nutrition score was not related to frailty phenotype. CONCLUSION: The study demonstrated that the NFA is a safe and feasible tool to screen target older adults and simultaneously evaluate their nutritional status and physical functionality. Validity of the NFA was partially confirmed by the significant association of the global and physical functionality scores with frailty phenotype. More studies are required to validate and maximize the applicability of the NFA in communities and institutions in Japan and elsewhere.

Assessment using serum insulin-like growth factor-I and bone mineral density is useful for detecting prevalent vertebral fractures in patients with type 2 diabetes mellitus.

Bone mineral density (BMD) is less useful for evaluating fracture risk in type 2 diabetes. This study showed for the first time that combined evaluation by serum insulin-like growth factor-I and BMD is useful to assess the risk of vertebral fracture in postmenopausal women and men with type 2 diabetes. INTRODUCTION: BMD is less useful for evaluating fracture risk in type 2 diabetes mellitus (T2DM). We aimed to examine the usefulness of combined evaluation by BMD and serum insulin-like growth factor-I (IGF-I) to assess the risk of vertebral fracture (VF) in T2DM. METHODS: In this cross-sectional study, 412 postmenopausal women and 582 men with T2DM, whose BMD, bone turnover markers, and serum IGF-I were measured, were enrolled. The association of BMD alone, serum IGF-I alone, and combined assessment by BMD and IGF-I with the presence of VF was examined. RESULTS: Multiple logistic regression analyses showed that IGF-I as well as BMD T-score at lumbar (L) and femoral neck (FN) were significantly associated with VF except for IGF-I in men, respectively. Receiver operating characteristic curves showed that the cutoff values of IGF-I, L T-score and FN T-score were 127 ng/mL, - 1.78, and - 2.02 in postmenopausal women and 127 ng/mL, - 1.67, and - 1.24 in men. Based on the cutoff vales, the subjects were divided into four categories. The category of lower IGF-I and lower T-scores had a significant increased risk of VF compared to higher IGF-I and higher T-scores both in postmenopausal women and in men. The sensitivity and specificity of the combined assessment to detect VF were better compared to using BMD alone or IGF-I alone. CONCLUSIONS: This is the first study to show that in addition to BMD measurement, the assessment using serum IGF-I is useful to estimate the prevalence of VF in patients with T2DM.

Scaphoid nonunion with carpal ligament injury - radiological, arthroscopical assessment and clinical results.

The purpose of this study was to review the clinical results of carpal ligaments injuries with scaphoid nonunion. We hypothesized that scaphoid nonunion with carpal ligament injury is associated with clinical result. We retrospectively reviewed 60 cases of -Herbert screw fixation with bone graft for scaphoid nonunions. Scapholunate (SL) and lunotriquetral (LT) ligaments lesions were confirmed by arthroscopy. Approximately half of the nonunion scaphoid cases had carpal ligaments injuries. At final follow-up evaluation, wrist function as evaluated by the Mayo wrist score was excellent in 34 patients, good in 16 patients, fair in 8 patients, and poor in 2 patients. Cases with both SL/LT ligaments injuries tended to have decreased wrist flexion-extension motion. Our results suggest that there is an indication for arthroscopy in scaphoid nonunion if surgical fixation is offered to avoid detrimental effects of an undiagnosed ligament tear.

Clinical assessment and prevalence of parkinsonism in Japanese elderly people.

BACKGROUND: Parkinsonism is often observed in the elderly. To clarify the prevalence of parkinsonism-associated diseases and conditions, we conducted a population-based study in a rural island town in western Japan, Ama-cho. METHODS: Participants included 924 subjects aged 65 years or older residing in the town. Between 2008 and 2011, participants were assessed via standardized neurological examination scales, and Brain MRIs were carried out in 2010. Based on the results of assessment using the modified Unified Parkinson's Disease Rating Scale and a standardized neurological examination, participants were diagnosed as having parkinsonism or mild parkinsonian signs (MPS), or as displaying normal motor conditions (M-normal). RESULTS: Of the 729 participants screened, 70 subjects were diagnosed as having parkinsonism, corresponding to a crude prevalence rate of 9.6% (95% CI, 7.9-11.3%), while 167 MPS subjects (22.9%) and 492 subjects experiencing M-normal (67.5%) were observed. Parkinsonism was found in association with various diseases such as Vascular parkinsonism, Lewy body disease, Alzheimer's disease (AD), and idiopathic normal-pressure hydrocephalus. Among the subjects with dementia, the proportion with parkinsonism was higher in the non-AD dementia group. CONCLUSION(S): Parkinsonism occurs in association with several diseases in elderly people. Parkinsonism was also found to be commonly associated with cognitive impairment.

Impact of levofloxacin dose adjustments by dispensing pharmacists on adverse reactions and costs in the treatment of elderly patients.

Ensuring an appropriate dosage of renally eliminated drugs for patients with renal insufficiency is important for preventing adverse drug reactions. We investigated the effectiveness of interventions by pharmacists in a hospital pharmaceutical department. The comparative study was performed at Gifu Municipal Hospital in Japan from March to August 2011, and included an intervention (142 patients) and a control group (98 patients). Upon receiving a prescription of levofloxacin for patients aged > or = 75 years, pharmacists evaluated the patients' kidney function and adjusted the appropriate dosage at the time of dispensation. In the intervention and control groups, levofloxacin-induced adverse reactions developed in 6 of 142 (4.2%) and 13 of 98 (13.3%) patients, respectively (p < 0.05). The cost of reducing levofloxacin per patient was yen 191.1 and yen 0 in the intervention and control groups, respectively. The cost per patient for adverse reaction treatments and examinations was yen 15.5 and yen 290.0 in the intervention and control groups, respectively. The intergroup difference in the total cost per patient was yen 465.6. Dose adjustment of levofloxacin at the time of dispensation by the pharmacist for patients aged > or = 75 years resulted in a decrease in the incidence of adverse reactions and cost. These findings can be applied not only to hospitals, but also to community pharmacies, because the intervention, which is a manual system, is simply performed when pharmacists are dispensing drugs.

Parental employment, income, education and allergic disorders in children: a prebirth cohort study in Japan.

SETTING: Epidemiological evidence on the relationship between socio-economic status and allergic disorders has been inconsistent. OBJECTIVES: We examined the associations between maternal employment, maternal job type, household income, and paternal and maternal educational levels and the risk of allergic disorders in Japanese children aged 4.5 years. DESIGN: Subjects were 480 mother-child pairs. Definitions of wheeze and eczema symptoms were based on criteria of the International Study of Asthma and Allergies in Childhood. Data on self-reported doctor-diagnosed asthma and atopic eczema were available. RESULTS: Compared with children whose mothers had received less than 13 years of education, those with mothers with ≥15 years of education had a significantly increased risk of wheeze and doctor-diagnosed asthma: the adjusted ORs were respectively 2.41 (95%CI 1.18-5.17) and 2.70 (95%CI 1.03-8.08). Fifteen years or more of paternal education was independently associated with an increased risk of eczema, but not of doctor-diagnosed atopic eczema (adjusted OR 1.89, 95%CI 1.07-3.42). Mother's employment, mother's job type and household income were not related to any of the outcomes. CONCLUSIONS: Higher maternal educational level may increase the risk of wheeze and asthma, while higher paternal educational level may increase the risk of eczema.

A class-wide phylogenetic assessment of Dothideomycetes.

We present a comprehensive phylogeny derived from 5 genes, nucSSU, nucLSU rDNA, TEF1, RPB1 and RPB2, for 356 isolates and 41 families (six newly described in this volume) in Dothideomycetes. All currently accepted orders in the class are represented for the first time in addition to numerous previously unplaced lineages. Subclass Pleosporomycetidae is expanded to include the aquatic order Jahnulales. An ancestral reconstruction of basic nutritional modes supports numerous transitions from saprobic life histories to plant associated and lichenised modes and a transition from terrestrial to aquatic habitats are confirmed. Finally, a genomic comparison of 6 dothideomycete genomes with other fungi finds a high level of unique protein associated with the class, supporting its delineation as a separate taxon.

Functional and locomotive characteristics of stroke survivors in Japanese community-based rehabilitation.

OBJECTIVE: The purposes of this study were as follows: (1) to compare the characteristics of functional fitness of Japanese stroke survivors with those of control subjects of a similar age; and (2) to relate these characteristics to the extent of physical impairment and the period after stroke onset to better design community-based rehabilitation programs for stroke survivors. DESIGN: One hundred fifty-three stroke survivors who participated in community-based rehabilitation and 119 control subjects were measured. Twelve performance test items were designed to assess functional fitness. RESULTS: The average functional fitness score for the stroke survivors was significantly lower than that of the control group. However, some survivors had higher performance scores than the control group. Significant correlations were shown between some functional fitness items and Brunnstrom recovery stage in the stroke survivors. CONCLUSION: The large variability in functional fitness scores for stroke survivors indicates a need to design variable rehabilitation programs so that survivors can be grouped according to their specific levels of functional fitness.

Dose distributions in a human head phantom for neutron capture therapy using moderated neutrons from the 2.5 meV proton-7Li reaction or from fission of 235U.

The feasibility of neutron capture therapy (NCT) using an accelerator-based neutron source of the 7Li(p,n) reaction produced by 2.5 MeV protons was investigated by comparing the neutron beam tailored by both the Hiroshima University radiological research accelerator (HIRRAC) and the heavy water neutron irradiation facility in the Kyoto University reactor (KUR-HWNIF) from the viewpoint of the contamination dose ratios of the fast neutrons and the gamma rays. These contamination ratios to the boron dose were estimated in a water phantom of 20 cm diameter and 20 cm length to simulate a human head, with experiments by the same techniques for NCT in KUR-HWNIF and/or the simulation calculations by the Monte Carlo N-particle transport code system version 4B (MCNP-4B). It was found that the 7Li(p,n) neutrons produced by 2.5 MeV protons combined with 20, 25 or 30 cm thick D20 moderators of 20 cm diameter could make irradiation fields for NCT with depth-dose characteristics similar to those from the epithermal neutron beam at the KUR-HWNIF.

[Assessment of physical activities from functional physical fitness tests research for patients with chronic obstructive pulmonary disease].

The purpose of this study was to determine whether the level of physical activity (as measured by 12 functional physical fitness tests) differed between patients with chronic obstructive pulmonary disease (COPD) and normal subjects. Fifty male patients with COPD (70.4 +/- 7.1 yr) and 193 age-matched normal subjects (71.2 +/- 5.2 yr) participated in the study. We administered twelve functional physical fitness tests that were designed to represent muscle strength, muscular endurance, reaction, flexibility, balance, regulation and manipulation. Cardiorespiratory fitness was measured by an incremental, symptom-limited exercise test to the maximal tolerable level on a cycle ergometer, and by the 6-min walk distance. Further, we evaluated what the relationships were between cardiorespiratory fitness and physical activities. The results showed that there were significant differences between COPD and normal groups in cardiorespiratory fitness [peak oxygen uptake (15.7 +/- 4.8 ml/kg/min vs. 23.9 +/- 6.5 ml/kg/min, p < 0.05), peak load (77.9 +/- 33.7 watts vs. 110.3 +/- 37.9 watts, p < 0.05) and 6-min walk distance (466.4 +/- 106.3 m vs. 540.4 +/- 78.3 m, p < 0.05)] and muscular endurance [arm curl (22.6 +/- 5.0 rep/30 s vs. 25.2 +/- 6.0 rep/30 s, p < 0.05), Keeping a half-squat position (32.6 +/- 16.4 s vs. 42.8 +/- 17.7 s, p < 0.05)] and regulation (27.2 +/- 9.4 s vs. 23.3 +/- 5.8 s, p < 0.05) in functional physical fitness test. There were significant correlations between cardiorespiratory fitness, and muscular endurance and regulation. Furthermore, there were significant correlations between FEV1.0 and FEV1.0% pred, and regulation. Therefore, it is important that, besides exercise prescriptions based on the criteria of symptom-limited exercise tests, development of exercise programs based on the level of physical activities may be necessary for patients with COPD.

[Assessment of left ventricular function with the solid-state digirad 2020tc Imager].

Multigated equilibrium radionuclide ventriculography from best septal position (LAO view) was performed in 17 patients with cardiac disease with a single detector Anger-type gamma camera (GCA 602A, Toshiba), then immediately imaged with a solid-state, multi-crystal gamma camera (Digirad 2020tc Imager). Acquisition times were the same of 10 minutes. The solid-state gamma camera uses CsI(Tl) as the scintillation material and a Si photodiode. CsI(Tl) has a higher density and higher atomic number than NaI(Tl), so that its efficiency for detecting gamma rays is higher. To confirm this, total acquisition counts in 17 patients obtained from the 2020tc Imager were significantly higher than those obtained from the Anger-type camera (7847 +/- 2061 K vs. 4427 +/- 1162 K counts, p < 0.0001). In comparing left ventricular ejection fractions obtained from the Anger-type camera and the 2020tc Imager data, an excellent correlation was revealed with a correlation coefficient of 0.97 (p < 0.0001). Again, peak ejection rate and peak filling rate obtained from the 2020tc Imager data correlated well with those obtained from the Anger-type camera data (r = 0.93, p < 0.0001 and r = 0.80, p < 0.001, respectively). These data reveal that the 2020tc Imager has an excellent data collection efficiency and a high reliability in assessment of left ventricular function. Thus, the solid-state gamma camera was thought to be a useful hardware in nuclear cardiology.

Graft size assessment and analysis of donors for living donor liver transplantation using right lobe.

BACKGROUND: Modality of living donor liver transplantation (LDLT) has been expanded to adult cases. However, the safety of right lobectomy from living donors has not yet been proven. METHODS: A total of 62 cases of LDLT, using the right lobe, were reviewed. Study 1: Discrepancy between estimated graft volume and actual graft weight was evaluated. Study 2: Postoperative liver functions were analyzed in relation to residual liver volume (RLV) or age. Residual liver volume of donors was defined using two indices, (RLV = estimated whole liver volume - estimated graft volume and %RLV = RLV/estimated whole liver volumex100). Donors were divided into two groups on the basis of either %RLV (<40%; 40%< or =) or age (<50 years old; 50 years old < or =). Study 3: Right lobe donors were compared with left lobe donors (35 cases) in terms of their postoperative liver functions. RESULTS: Study 1: The relationship between estimated graft volume and actual graft weight was linear (y=159.136+0.735x, R2=0.571, P<0.001). Study 2: %RLV ranged from 23.5% to 55.8% (mean +/- SD: 43.2+/-6.0). Fifteen cases showed %RLV less than 40%. Postoperative bilirubin clearance was delayed in that group (%RLV<40%). Serum total bilirubin values on postoperative day 7 in the older group (age > or =50) were significantly higher than those in the younger group (age<50). Study 3: Postoperative liver functions of right lobe donors were significantly higher than those of left-lobe donors. Eleven donors (17.7%) had surgical complications, all of which were cured with proper treatment. CONCLUSIONS: Right lobectomy from living donors is a safe procedure with acceptable morbidity, but some care should be taken early after the operation for donors with small residual liver and aged donors.

Outpatient laparoscopic cholecystectomy: patient outcomes after implementation of a clinical pathway.

OBJECTIVE: To determine the success of a clinical pathway for outpatient laparoscopic cholecystectomy (LC) in an academic health center, and to assess the impact of pathway implementation on same-day discharge rates, safety, patient satisfaction, and resource utilization. SUMMARY BACKGROUND DATA: Laparoscopic cholecystectomy is reported to be safe for patients and acceptable as an outpatient procedure. Whether this experience can be translated to an academic health center or larger hospital is uncertain. Clinical pathways guide the care of specific patient populations with the goal of enhancing patient care while optimizing resource utilization. The effectiveness of these pathways in achieving their goals is not well studied. METHODS: During a 12-month period beginning April 1, 1999, all patients eligible for an elective LC (n = 177) participated in a clinical pathway developed to transition LC to an outpatient procedure. These were compared with all patients undergoing elective LC (n = 208) in the 15 months immediately before pathway implementation. Successful same-day discharges, reasons for postoperative admission, readmission rates, complications, deaths, and patient satisfaction were compared. Average length of stay and total hospital costs were calculated and compared. RESULTS: After pathway implementation, the proportion of same-day discharges increased significantly, from 21% to 72%. Unplanned postoperative admissions decreased as experience with the pathway increased. Patient characteristics, need for readmission, complications, and deaths were not different between the groups. Patients surveyed were highly satisfied with their care. Resource utilization declined, resulting in more available inpatient beds and substantial cost savings. CONCLUSIONS: Implementation of a clinical pathway for outpatient LC was successful, safe, and satisfying for patients. Converting LC to an outpatient procedure resulted in a significant reduction in medical resource use, including a decreased length of stay and total cost of care.

Accuracy of two simple methods for the assessment of health-related physical fitness.

We have developed a useful equation for estimating health-related physical fitness age. This version of health-related fitness age was developed as an extension of the biological age index and is useful for evaluation of individual differences in functional abilities of middle-aged and older adults. This measure consists of 4 independent variables fitness (VO2 max, standing trunk flexibility, %fat, and grip strength). However, direct measurement of maximal oxygen uptake (VO2 max) is an invasive clinical procedure and not practical for large scale work. In the current study, we attempted to assess the fitness age more feasibly. We selected a questionnaire method and a 12-min. submaximal treadmill walk test as substitutes for the VO2 max test. The three fitness ages were computed for 23 Japanese men (M(age) 54.7 +/- 10.7 yr.), using actual VO2 max (actual fitness age), questionnaire VO2 max (predicted questionnaire fitness age), and treadmill VO2 max (predicted treadmill fitness age). Predicted questionnaire fitness age (61.0 +/- 10.5 yr.) and predicted treadmill fitness age (60.0 +/- 12.4 yr.) were significantly correlated with actual fitness age (60.1 +/- 12.4 yr.) (r= .96 and .97, respectively). There were no significant differences among the three indices, but there was a significant difference between actual fitness age and chronological age (p<.05). For VO+/-2 max substituting the questionnaire for the treadmill estimate is acceptable in assessing fitness age and reducing the clinical risk for middle-aged and older Japanese men.
