BACKGROUND: Predicting adverse health events and implementing preventative measures are a necessary challenge. It is important for healthcare planners and policymakers to allocate the limited resource to high-risk persons. Prediction is also important for older individuals, their family members, and clinicians to prepare mentally and financially. The aim of this study is to develop a prediction model for within 11-year dependent status requiring long-term nursing care or death in older adults for each sex. METHODS: We carried out age-specified cohort study of community dwellers in Nisshin City, Japan. The older adults aged 64 years who underwent medical check-up between 1996 and 2000 were included in the study. The primary outcome was the incidence of the psychophysically dependent status or death or by the end of the year of age 75 years. Univariable logistic regression analyses were performed to assess the associations between candidate predictors and the outcome. Using the variables with p-values less than 0.1, multivariable logistic regression analyses were then performed with backward stepwise elimination to determine the final predictors for the model. RESULTS: Of the 1525 female participants at baseline, 105 had an incidence of the study outcome. The final prediction model consisted of 15 variables, and the c-statistics for predicting the outcome was 0.763 (95% confidence interval [CI] 0.714-0.813). Of the 1548 male participants at baseline, 211 had incidence of the study outcome. The final prediction model consisted of 16 variables, and the c-statistics for predicting the outcome was 0.735 (95% CI 0.699-0.771). CONCLUSIONS We developed a prediction model for older adults to forecast 11-year incidence of dependent status requiring nursing care or death in each sex. The predictability was fair, but we could not evaluate the external validity of this model. It could be of some help for healthcare planners, policy makers, clinicians, older individuals, and their family members to weigh the priority of support.

BACKGROUND: To let the early elderly live well, understanding how lifestyle and psychosocial factors related to a decline in competence in daily living is important. METHODS: We investigated the associations between lifestyle and psychosocial factors at age 64 years and a decline in the Tokyo Metropolitan Institute of Gerontology Index of Competence score of ≥ 2 points at age 70 years among the participants in comprehensive medical check-ups living in a city in Japan. Multivariable logistic regression analyses were performed separately for men and women. RESULTS: Of the 1113 eligible men and 1203 eligible women, 110 men and 80 women showed a deteriorated competence in daily living during the 6 years. In men, risk was increased with ≥ 2 nighttime awakenings (multivariable odds ratio [mOR] 2.14, 95% confidence interval [CI] 1.19-3.86) and living alone (mOR 4.68, 95% CI 1.22-18.0), whereas risk was significantly decreased with a medium or fast gait (mOR 0.37 and 0.21, 95% CI 0.21-0.67 and 0.08-0.58) and high academic achievement (mOR 0.32 and 0.43, 95% CI 0.19-0.53 and 0.25-0.72). In women, risk was decreased with high life satisfaction (mOR 0.39, 95% CI 0.16-0.91) and participation in community activities (mOR 0.50, 95% CI 0.29-0.86) but increased with depressive mood (mOR 1.86, 95% CI 1.09-3.18). CONCLUSION Living alone for men and low life satisfaction for women at age 64 years were markedly associated with the risk of a subsequent declining competence in daily living.

BACKGROUND: The effect of the redox state of human serum albumin (HSA) on the antioxidant properties of the entire body has been a focus of recent research. The usefulness of HSA redox state as a biomarker for reducing oxidative stress has been investigated in clinical settings; however, evidence for its significance as a health index in non-clinical settings is yet to be established. This study aimed to examine the associations between HSA redox state and the atherosclerotic indices of carotid intima-media thickness (IMT) and plaque formation in a rural Japanese population. METHODS: We conducted a cross-sectional study as part of a health check-up program in the rural area of Hokkaido, Japan, at the end of August 2013. A total of 281 residents (124 men and 157 women) were included in the final analysis. Lifestyle-related data were obtained through a self-reported questionnaire, and ultrasound examinations were performed to measure IMT and determine plaque formation. The high-performance liquid chromatography postcolumn bromocresol green method was used to separate HSA into human nonmercaptalbumin and human mercaptalbumin (HMA). RESULTS: We found a significant negative relationship between the fraction of HMA [f(HMA)] and IMT (standardized β = - 0.132, p = 0.03). Moreover, f(HMA) was significantly associated with plaque formation (p < 0.01) with an odds ratio of 0.89 (95% confidence interval, 0.81-0.97) for every 10% increment in f(HMA). CONCLUSIONS We found that the HSA redox state, as determined by f(HMA), was associated with atherosclerotic indices in Japanese subjects. These results suggest that the HSA redox state indicates the risk of developing atherosclerosis.

This paper proposes a method for evaluating and scoring the activities of rehabilitation service users in order to pinpoint the problems with the health service of this kind and set the adequate targets for each user. Sincs the Nursing Care Insurance System was introduced in Japan in 2000, it has been argued that home-visit rehabilitation services should be excluded from home-nursing care services. However, the methods of certifing that nursing care is required are not fully established yet for setting the rehabilitation targets for service users. As things stand, it is recommended that such a method as the Functional Independence Measure (FIM) or the Barthel Index (BI) should be utilized. However, these methods only evaluate “performing activities” (the activities that a user usually performs). In order to set the users' targets, we thought it necessary to establish a method for evaluating “possible activities” (the activities that a user is able to perform at his/her full capacity). We have established a method called Functional Scoring (FS) which evaluates and scores the both performing and possible activities based on the same evaluation items. We conducted experimental evaluations on the home-visit rehabilitation users for one year from October 2005 to September 2006. When the first evaluations in 2005 were compared with the second evaluations in 2006, the total score of the performing activities significantly increased from 44.1±13.7 to 47.8±14.2 (P<0.05). Although the total score of the possible activities did not significantly increase, it demonstrated an upward trend from 49.6±13.2 to 51.6±13.5. The result suggests that our method is useful for distinguishing between the performing and possible activities. The proposed method enables us to adequately recognize the problems each user has, and to set the rehabilitation target for each user, which can be shared between the user, care personnel, and care service provider.

We performed combination therapy with modified oxaliplatin/l-LV/5-FU (mFOLFOX) in a patient with recurrent colorectal cancer who had peritonitis carcinomatosis. In this patient, mFOLFOX therapy resulted in disappearance of ascites and a decrease in carbohydrate antigen 19-9 (CA19-9), and improved quality of life (QOL) of the patient. This 62-year-old man was diagnosed with ascending colon cancer and metastatic cancer of the liver. Right hemicolectomy and right hepatic lobectomy were performed. We had started to treat with TS-1 in ambulatory care, however, he had peritonitis carcinomatosis with massive ascite reservoir on CT and peritoneal dissemination after a half year postoperatively. Furthermore, his ECOG Performance Status (PS) was rated as level 3. Therefore, we performed puncture of ascites and palliative mFOLFOX6 therapy. After ten courses, ascites and abdominal induration had disappeared and PS recovered to level 1. At present, CPT-11/l-LV/5-FU (FOLFIRI) are being administered for peripheral neuropathy and metastatic tumor associated with mFOLFOX6. The patient is spending his daily life satisfactory after FOLFIRI without abdominal swelling or ascites, and thus mFOLFOX6 may be an option for palliative therapy against massive ascites in patients with advanced colorectal cancer. The usefulness of palliative mFOLFOX6 therapy for patients with massive ascites should be evaluated in a well-designed clinical trial.Palliat Care Res 2008; 3(2): 316-320

A 71-year-old man had sudden onset of left lower limb swelling and consulted an orthopedic surgeon 14 days later. Venous echography demonstrated compression of the left iliac vein and the thrombus of the common iliac vein. After emergency admission, conservative therapy was given for 7 days, but the symptoms did not sufficiently diminish and a thrombus was also present. We therefore performed femoro-iliac cross-over vein bypass using a 10mm ringed ePTFE graft. Symptoms were completely improved and the graft was shown to be patent by echography after 3 months.

This study evaluated factors influencing residual aortic regurgitation (AR) after valve re-suspension surgery for acute type A aortic dissection. From January 1996 through December 2002, 63 patients were treated for acute type A dissection at our institution. Among these 63 patients, pre-and postoperative echocardiograms were available in 38 patients who underwent surgery combined with native aortic valve re-suspension. These 38 patients were divided into 2 groups according to the postoperative AR grade, i. e.: AR group: AR grade≥II (n=6), no-AR group: AR grade≤I (n=32). The severity of pre and postoperative AR was assessed by transthoracic or transesophageal echocardiography. The preoperative diameters of mid ascending aorta and sinotubular junction, and the percentage of the circumference of the dissection at the sinotubular junction level was measured by enhanced CT scan. Preoperative patient backgrounds were similar in both groups. The preoperative AR grade in the AR group was significantly greater than that of the no-AR group (2.25±1.17: 0.69±0.91, p<0.001). The tear was more frequently located in the ascending aorta in the AR group than in the no-AR group (66.7%: 37.5%, p<0.05). The percentage of circumference of the dissection at the sinotubular junction level did not affect the preoperative AR grade, but it did show a tendency to influence the severity of postoperative AR, though the difference was not significant. Three patients (7.9%) had AR grade III at the time of discharge, but did not clinically require further surgical intervention. Preoperative significant AR and the location of the tear in the ascending aorta are associated with postoperative residual AR after aortic valve re-suspension. The percentage of circumference of the dissection at the sinotubular junction level might influence the severity of postoperative AR.

A survey was conducted by sending questionnaires to 466 doctors working at nine hospitals affiliated with the Aichi Prefectural Federation of Agricultural Cooperatives for Health and Welfare (Kohseiren).
The survey found that the length of service was under 5 years in 60% of the respondents and that many of them identified themselves strongly with the department of the teaching hospital where they were trained.
They were found to be little intersted in the present situation of the agricultural cooperatives and Japanese agriculture. However, they said they were satisfied with the present working conditions, because they could show their skills. Most approved of organ transplants after brain death but disapproved of human cloning. They showed a positive attitude toward the allowing of each patient to give access to his or her clinical records and standardization of medical treatment. Some 67% of the doctors admitted they had made medical mistakes and keenly realized the necessity of risk management.
While feeling uneasy about the recent upsurge of lawsuits brought by patients about medical treatment, they said they are endeavoring to provide safe and high quality medical service. Their recent concerns were rearrangement of dispensaries based on the subspecialty, reinforcement of postgraduate courses in medical schools and the postgraduate training system which will be a legal obligation from 2005. They suported the reform plans for the national medical service for aged patients and recognized the necessity of joining hands with local agricultural cooperatives in providing nursing care services. They said they wish to continue their career as a physican at the Kohseiren hospital.

In two cases of thromboangitis obliterans (TAO) a popliteal-posterior tibial-peroneal artery sequential bypass was attempted through a median approach. The 1st case underwent the operation successfully with non-reversed saphenous vein graft. However, only popliteal-peroneal bypass was carried out in the 2nd patient because the posterior tibial artery was severely affected. In surgery of TAO patients, careful assessment of preoperative angiographic findings is important to select the site of distal anastomosis. We found that the posterior tibial artery and the peroneal artery are easily accessible through the medial route in the proximal half of the lower leg and that peroneal artery revascularization was effective for limb salvage.
