Aim: This study aimed to examine the relationship between blood coagulability and sense of burden among caregivers of patients with senile dementia of the Alzheimer type., Methods: A cross-sectional study was carried out involving healthy older caregivers who lived with their patients with senile dementia of the Alzheimer type. We evaluated the Zarit Burden Interview score, levels of von Willebrand factor antigen, D-dimer, thrombin-antithrombin III complex, tissue plasminogen activator/plasminogen activator inhibitor type 1 complex, number of chronic diseases, body mass index and number of medications. A linear regression model was used to estimate adjusted associations., Results: Thrombin-antithrombin III complex levels were higher in female caregivers than in male caregivers (P = 0.07). Headaches were significantly more frequent in female caregivers than in male caregivers, as assessed by a visual analog scale (P < 0.01). The number of chronic diseases and body mass index were positively associated with levels of tissue plasminogen activator/plasminogen activator inhibitor type 1 complex (P < 0.05). Similarly, the number of medications was positively associated with levels of D-dimer (P < 0.05). However, the Zarit Burden Interview score was not associated with blood coagulability (P > 0.05)., Conclusions: The present study found that the number of chronic diseases and body mass index were associated with blood coagulability, and that female caregivers were more prone to headaches and higher blood coagulability than male caregivers. These findings highlight the essential nature of health management during caregiving. The impact of caregiver burden on blood coagulability is likely to differ depending on the long-term or short-term psychological stress associated with caregiving conditions.

Objectives: To report long-term outcome survival analysis of docetaxel-based chemotherapy combined with dexamethasone in castration-resistant prostate cancer patients (Japan-Multinational Trial Organization Pca10-01 trial)., Methods: The Japan-Multinational Trial Organization Pca10-01 phase II trial was a multicenter, prospective single-arm, phase II trial both in non-metastatic and metastatic castration-resistant prostate cancer patients that was organized by The Japan-Multinational Trial Organization. Patients received 75 mg/m 2 of docetaxel (every 21 days) and 0.5 mg of dexamethasone orally twice a day continuing throughout the treatment period. The primary end-point of this additional analysis was overall survival. Secondary end-points were progression-free survival and safety., Results: Between January 2011 and February 2014, a total of 76 chemotherapy-naïve castration-resistant prostate cancer patients were enrolled. The median overall survival time was 42.5 months. The median overall survival time of M1 patients was 40.5 months (M0: not reached). The median progression-free survival time was 13.2 months (M0: 15.7 months and M1: 12.3 months). The multivariate analysis predicting overall survival of M1 patients showed that time to castration-resistant prostate cancer (≥20 months) was an independent parameter (hazard ratio 0.39, P = 0.023). Regarding the safety analysis, 36 out of 74 patients (48.6%) suffered from any grade of adverse events after the protocol treatment, and 18 patients (24.3%) had grade ≥3 adverse events., Conclusions: Docetaxel-based chemotherapy combined with dexamethasone can achieve excellent survival efficacy not only in M0 castration-resistant prostate cancer patients, but also in M1 castration-resistant prostate cancer patients., (© 2019 The Japanese Urological Association.)

Aim: The risk factors for ischemic heart disease (IHD) or cerebrovascular accident (CVA) in elderly diabetic individuals with type IIb dyslipidemia are not fully known. Therefore, we investigated the relationship between lipid levels and IHD and CVA in diabetic individuals with type IIb dyslipidemia., Method: The Japan Cholesterol and Diabetes Mellitus Study is a prospective cohort study of 4014 type 2 diabetic patients (1936 women; age 67.4 ± 9.5 years). The primary end-points were the onset of IHD or CVA. Lipid and glucose levels, and other factors were investigated in relation to the occurrence of IHD or CVA. A total of 462 participants were included in the group of patients with type IIb dyslipidemia., Results: The 462 diabetic participants with type IIb dyslipidemia were divided into those who were aged <65 years, 65-74 years and >75 years (n=168, 190 and 104, respectively). High-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol/HDL-C were significantly associated with the risk of cardiovascular events in diabetic individuals with type IIb dyslipidemia who were aged <65 years, and HDL-C and diastolic blood pressure was significantly associated with cardiovascular events in patients aged 65-74 years. Non-HDL-C was not significantly associated with the risk of cardiovascular events. Multiple regression analysis showed that lower HDL-C was significantly associated with the risk of cardiovascular events in diabetic individuals with type IIb dyslipidemia who were aged <65 years and 65-74 years., Conclusions: Lower HDL-C was an important risk factor for cardiovascular events in diabetic individuals with type IIb dyslipidemia who were aged <75 years., (© 2013 Japan Geriatrics Society.)

To investigate factors affecting the place of death of patients receiving home care services, we performed a retrospective cohort study using 252 elderly Japanese patients. During a 3-year period, 40 patients died at home (78.4 ± 12 years olds), and 59 patients died at hospitals (77.6 ± 13.4 years olds). Patient profiles, including their demographic characteristics, comorbidities, as well as formal and informal care levels were evaluated. Patients who died at home received a shorter term of home care, suffered malignancies more often and received visiting nurse services more often than those at hospitals. Age, gender, comorbidities, laboratory data, independency of activity of daily living (ADL), number of family looking after patients, number and dose of prescriptions and number of medical treatments such as decubitus were not different between these groups. Multivariate logistic regression analyses revealed that patients who died at home had an increased likelihood of suffering from malignancy (odds ratio = OR = 2.18, HR: 1.04-3.98, p = 0.049) and an increased likelihood of receiving visiting nurse services (OR = 3.13, HR: 1.08-6.21, p = 0.029) compared to those who died at hospitals. Thus, dying at home may be associated with cases of malignancy compared to other diseases in Japan, and it may be associated with a greater need for home visiting nurses. In conclusion, the nature of the patient's disease and the presence of visiting nurses influenced the decision regarding the patient's place of death. More study is necessary to better understand the end stages of death at home., (Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.)

The purpose of this study was to examine the prevalence of screening-detected depression and the association of depression with QoL in community-dwelling postmenopausal women living in three Asian countries. We examined self-reported questionnaires and conducted the study. A total of 698 community-dwelling postmenopausal women living in three Asian countries participated in this study. The mean age was 59.4±6.6 years (±SD) Depressive symptoms were assessed using a 15-item geriatric depression scale (GDS-15). Using the cut-off of 5/6 for the GDS-15, the percentages of subjects with depression were 39.0% of the Korean subjects, 29.2% of the Chinese subjects, and 33.9% of the Japanese subjects. For the assessment of QoL, we used the EQ-5D of the EuroQoL Group. The following five dimensions were assessed: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. The proportions of subjects reporting problems for each dimension were examined. Subjects with depression had significantly lower levels of some dimensions of QoL than those without depression in all three countries. In all three countries, 29.2-39.0% of community-dwelling postmenopausal women had screening-detected depression, which was significantly associated with a lower level of some dimensions of QoL. These results suggest that clinicians should pay more attention to depression in community-dwelling postmenopausal women., (Copyright © 2010. Published by Elsevier Ireland Ltd.)

Objectives: A comparison between the atheroprotective and osteoprotective effects of the selective estrogen receptor modulator (SERM) raloxifene and those of hormone replacement therapy (HRT) has not been made in elderly women., Methods: A randomized prospective controlled trial was performed in a cohort of 32 elderly Japanese women with osteoporosis receiving HRT (estriol plus medroxyprogesterone) for more than 1 year. In 16 randomly selected subjects, HRT was changed to raloxifene therapy (60mg/day, 71.4±3.4 years, SERM group). The other 16 patients were continued on HRT (71.8±2.9 years, HRT group). As a control group, 14 subjects were enrolled, did not take any medications and were age-matched to experimental patients (72.5±3.3 years, control group). Plasma lipids, TNFα, adiponectin, NO metabolites (NOx:NO2(-) and NO3(-)), cyclicGMP and bone-mineral density (BMD) were evaluated at baseline and at 26 and 52 weeks after enrollment., Results: SERM (Raloxifene) increased high-density-lipoprotein cholesterol levels and tended to decrease low-density-lipoprotein cholesterol levels (P=0.058) compared with baseline. Adiponectin, NOx and cGMP levels were significantly increased after 6 months compared with baseline or the HRT group. TNFα was decreased by raloxifene. In control subjects, no significant changes were observed in any of these markers. Bone-mineral density was higher at baseline in the raloxifene and HRT groups than in the control group, and BMD increased 12 months after baseline in the HRT and control group., Conclusion: SERM improved BMD and endothelial function in elderly postmenopausal women with osteoporosis who had received HRT, and these effects were comparable to or slightly stronger than those of HRT. Changes in adiponectin and TNFα may underlie the improvements in endothelial function, such as NO signaling., (Copyright © 2011 Elsevier Inc. All rights reserved.)

Aims: This study evaluated the presence of genetic mutations in relation to thrombosis or atherosclerosis in elderly women., Main Methods: This is an observational study of 93 Japanese women with a mean age of 80.9 years recruited from outpatient clinics of Nagoya University and its related hospitals. Ten single nucleotide polymorphisms (SNPs) were studied. Each gene studied acts in or is related to either blood coagulation (factor V Leiden, prothrombin G20210A, factor XIII Val34Leu, factor VII Arg353Gln, MTHFR C677T, beta-fibrinogen G-455A, PAI-1 4G/5G), metabolic syndrome-related pathways (PPARalpha Leu162Val), or endothelium/estrogen system (eNOS Glu298Asp, ERalpha IVS1-401). SNPs were analyzed for their relation to clinical values including lipids, B-type natriuretic peptide (BNP), fasting plasma glucose, tumor necrosis factor-alpha, interleukin-6, cyclic GMP, and nitric oxide metabolites., Key Findings: Comparisons between the distributions of different genotypes and clinical values showed three relationships. First, factor VII Arg353Gln and HDL-cholesterol (HDL-C) were linked to Arg/Arg carriers at higher levels (P=.049). The HDL-C to LDL-cholesterol ratio supported this link (P=.027). Second, eNOS Glu298Asp and triglycerides were linked to Glu/Glu carriers at higher levels (P=.031). Third, ERalpha IVS1-401 and BNP were related to CC genotype at lower levels (P=.031). Additionally, the last two relations showed that genotype does not influence the demarcation line of biomarkers, but the plasma/serum levels of biomarkers instead., Significance: Correlations of factor VII Arg353Gln with HDL-C and eNOS Glu298Asp with triglycerides are new findings. Polymorphisms in the endothelium/estrogen system and the heart failure marker BNP are also correlated, with ERalpha IVS1-401 being the first identified marker. SNPs may be helpful for understanding the pathophysiology of atherosclerotic diseases in elderly women.

Background: The long-term benefit of Helicobacter pylori eradication treatment that includes metronidazole on peptic ulcer disease in Japan is unclear. We investigated the rate of H. pylori re-infection and ulcer relapse after H. pylori eradication., Materials and Methods: A total of 266 patients with endoscopically confirmed peptic ulcer disease and H. pylori infection were treated with triple therapy of omeprazole 40 mg (20 mg b.i.d.), clarithromycin 800 mg (400 mg b.i.d.), and tinidazole 1000 mg (500 mg b.i.d.) for 7 days. Endoscopy with gastric biopsy was performed before and 1 month, 6 months, 1.5 years, and 3.5 years after therapy. H. pylori status was determined by H. pylori culture, rapid urease test, and histopathology. 13C-urea breath test was done at 6 months after eradication therapy. Treatment was deemed successful when all tests were negative at 6 months after therapy by endoscopic biopsy., Results: Successful H. pylori eradication was achieved in 262/266 (98.5%) patients with peptic ulcer. Total relapse of peptic ulcer occurred in 8/262 (3%) patients after eradication, with 3/262 (1.1%) occurring within 1.5 years after treatment and 5/262 (1.9%) within 3.5 years. All relapsed patients were found to be H. pylori-positive at the time of relapse. Of the 262 patients who experienced eradication, 20 (7.6%) were subsequently re-infected, six (2.3%) within 1.5 years and 14 (5.3%) within 3.5 years., Conclusion: Triple therapy with omeprazole, clarithromycin, and tinidazole (OCT) is useful for H. pylori eradication in Japan, but there is an appreciable re-infection rate in this population.
