To clarify characteristics of home care in rural areas in Japan, we investigated the actual status of home care in a rural area (Asuke town, Asahi town, Inabu town, northern part of Toyota city and Shimoyama village) in Aichi prefecture. The subjects were 149 patients who were under medical care and nursing supervision at home for the last 2 years and a half. Age, sex, ADL, prognosis, principal care-givers of the patients and distance from patients' houses to our hospital were compared with the average data of all the nurse stations in Japan (1996). The percentage of patients over 90 years old was 23.4% in this area as against 13.5% of the national average. Sex and ADL levels were similar to the average. The proportion of females as principal care-givers of patients was 80%, which is about average. However, the proportion ofdaughters-in-law was 51.7%, double of the national average. In 48 cases (32%), the time required to get to the hospital by car was over 31 min. This ratio was 3 times higher than that of the average data, and it took 50 min from farthest patient's house (35km). In prognosis, 66 patients died-44 cases (67%) in hospital and 22 cases (23%) at home.
Our questionnaire survey regarding patients' and care-givers' wishes was responded to by 38 of 47 principal care-givers who utilized our home care and nursing survice program. One half of care-givers were over 60 yearsold and had taken care of a patient for over 5 years. Mental stress, feeding and toileting were major problems most principal care-givers cited. However, they required services at a day-care institution for elderly patients and recovery of used paper diapers. Death at home was wished by 23 (61%) patients and care-givers, if they received enough medial care and welfare services.
These findings revealed that elderly people take care of elderly patients, their houses are far from the hospital and they wish to die at home. More collaboration among all providers of medical care and health and welfare services, and the establishment of an information network are necessary to improve these problems, resulting in safe, acceptable and satisfied home care for patients and care-givers.

STUDY DESIGN: Retrospective observational study. PURPOSE: We examined change in lumbrosacral spine alignment and low back pain (LBP) following total hip arthroplasty (THA) in patients with severe hip osteoarthritis (OA). OVERVIEW OF LITERATURE: Severe hip osteoarthritis has been reported to cause spine alignment abnormalities and low back pain, and it has been reported that low back pain is improved following THA. METHODS: Our target population included 30 patients (29 female, mean age 63.5 years) with hip OA who underwent direct anterior approach THA. There were 12 cases with bilateral hip disease and 18 cases with unilateral osteoarthritis. Visual analogue scale (VAS) scores for LBP and coxalgia, the Roland-Morris Disability Questionnaire (RDQ), and the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) were assessed before and after surgery. Spinal alignment metrics were measured before and after surgery. RESULTS: VAS for LBP change from preoperative to final postoperative observation was significantly improved (p < 0.05), as was VAS for hip pain (p < 0.001). RDQ improved significantly (p < 0.01). All five domains of JOABPEQ were significantly improved (p < 0.05). In terms of coronal alignment, lumbar scoliosis change from preoperative to last observation was significantly reduced (p < 0.05). There were no significant changes in the sagittal alignment metrics. In addition, there was a correlation between before and after RDQ difference and before and after lumbar scoliosis difference (p < 0.05). VAS for LBP (p < 0.05) as well as RDQ (p < 0.05) were significantly improved only in unilateral OA. Lumbar scoliosis was significantly improved in cases of unilateral OA (p < 0.05), but alignment did not improve in cases of bilateral OA (p=0.29). CONCLUSIONS: The present study demonstrates improvements in VAS for LBP, RDQ, and all domains of JOABPEQ. There were also significant reductions in lumbar scoliosis and an observed correlation of RDQ improvement with lumbar scoliosis improvement. We were able to observe improvements in lumbar scoliosis and low back pain only in cases of unilateral OA. It has been suggested that the mechanism of low back pain improvement following THA is related to compensatory lumbar scoliosis improvement.

Background/Aims: Nutritional factors associated with gastric cancer (GC) are not completely understood. We aimed to determine the effect of nutrient intake on the incidence of GC. Methods: This was a post hoc analysis of a prospective trial that evaluated modalities for GC screening in participants aged 30 to 74 years living in high-risk areas for GC in Japan between June 2011 and March 2013. The patients were followed up for GC incidence for 6 years. All participants completed a self-administered food frequency questionnaire (FFQ) upon enrollment before GC screening. Daily nutrient intake was calculated from the FFQ and dichotomized at each cutoff value using receiver operating characteristic analysis. Risk factors associated with GC incidence were investigated in terms of nutrient intake and participant characteristics using Cox proportional hazards regression analysis. Results: Overall, 1,147 participants were included in this analysis. The median age was 62 years, and 50.7% of the participants were men. The median follow-up period was 2,184 days.GC was detected in 25 participants during the follow-up. Multivariate Cox proportional hazards regression analysis revealed that the intake of sodium (adjusted hazards ratio [aHR], 3.905; 95% confidence interval [CI], 1.520 to 10.035; p=0.005) and vitamin D (aHR, 2.747; 95% CI, 1.111 to 6.788, p=0.029) were positively associated with GC incidence, whereas the intake of soluble dietary fiber (aHR, 0.104; 95% CI, 0.012 to 0.905; p=0.040) was inversely associated with GC incidence. Conclusions Daily high intake of sodium and vitamin D and low soluble dietary fiber intake are associated with GC incidence.

OBJECTIVESOur objectives were (1) to evaluate whether single spot urine is suitable media for longer-term phthalate esters exposure assessment, and (2) to estimate intake level of phthalate esters of Japanese pregnant women using urinary metabolites as an indicator of prenatal exposure level in their offspring.

METHODSWe analyzed nine metabolites (MMP, MEP, MnBP, MBzP, MEHP, MEOHP, MEHHP, MINP, MnOP) of seven phthalate esters in spot urine samples from 50 pregnant women by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Using four urine samples collected from each of 12 subjects from 50 pregnant women within 5-12 weeks, we compared intra- and interindividual variation in urinary metabolites by calculation of intraclass correlation coefficient (ICC). We estimated daily intakes of 50 pregnant women from their urinary metabolite concentrations.

RESULTSICCs for seven phthalate metabolite concentrations in single spot urine samples were: MMP (0.57), MEP (0.47), MnBP (0.69), MBzP (0.28), MEHP (0.51), MEHHP (0.43), and MEOHP (0.41) in 12 pregnant women. Phthalate ester metabolites had high detection rates in 50 subjects. The mean daily intake ranged from 0.01 to 2 mug/kg per day. The daily intake levels in all subjects were lower than corresponding tolerable daily intake (TDI) set by the European Food Safety Authority (EFSA), though maximum value for DnBP of 6.91 mug/kg per day accounted for 70% of TDI value.

CONCLUSIONSHigher ICCs indicated that phthalate metabolite levels in single spot urine could reflect longer-term exposure to the corresponding diesters of subjects. Although the current exposure level was less than TDIs, further studies and exposure monitoring are needed to reveal the toxicity of phthalate esters to sensitive subpopulation.
