Objectives This study explored possible associations between chemical substances and sick building syndrome (SBS)-type symptoms of residents living in new houses in Japan. Methods We randomly sampled 5,709 newly built conventional homes. In the end, 1,479 residents in 425 households completed a questionnaire survey and agreed to environmental monitoring for indoor aldehydes and volatile organic compounds (VOCs) to be conducted in their homes. If the residents had complained about at least one SBS-related symptom, they were classified as suffering from SBS. Multiple logistic regression analysis was used to select predictive chemical factors of SBS symptoms. Results About 14% of the subjects suffered from SBS. Many aldehydes and VOCs were associated factors of optical, nasal, and gular symptoms in univariate analysis. After adjustment for other possible risk factors, formaldehyde dose-dependently showed to be a significant risk factor for SBS. Several chemicals had tendency to be associated with SBS symptoms. Conclusions Chemicals detected in Japanese newly built houses tend to increase the risk of subjective symptoms in residents suffering from SBS. © Springer-Verlag 2009. Source

The thermo-physical properties of magnetic fluid (solvent, water; nano-particulates, magnetite) were elucidated in order to examine its temperature dependency in the presence and absence of a magnetic field. Heat transfer by natural convection was also investigated around a horizontal thin wire, which was heated uniformly in the presence and absence of a magnetic field in order to estimate the heat transfer characteristics. Various thermal properties of the magnetic fluid and their temperature dependency were clarified in the present research. It was also found that the heat transfer coefficient coincides well with the conventional heat-transfer correlation of natural convection heat transfer around a horizontal heated thin wire by applying the values of thermo-physical properties obtained in the present measurement. © 2015 The Society of Chemical Engineers, Japan.

Background: Prevalence of chronic kidney disease (CKD) is estimated to be 13.3 million in Japan, but patient characteristics during the predialysis period (CKD stages 3-5) are not well studied. Methods: We established the Chronic Kidney Disease Japan Cohort (CKD-JAC) to study the incidence of cardiovascular disease (CVD), end-stage renal disease (ESRD), and all-cause mortality in predialysis patients treated by nephrologists for 4 years. The inclusion criteria were (1) Japanese and Asian patients living in Japan, (2) age 20-75 years, and (3) estimated glomerular filtration rate (eGFR) 10-59 ml/min/1.73 m2. Results: We analyzed 2977 participants for baseline characteristics. Mean eGFR was 28.6 ± 11.8 ml/min/1.73 m2, and mean albuminuria was 976 ± 1340 mg/g Cr. In our study, 91.9% of participants had hypertension, but it was well controlled (131/76 mmHg). Angiotensin converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) were used by most participants. Less than 15% of participants had history of ischemic heart disease, and 11.5% had history of stroke. Heart failure and arteriosclerosis obliterans were present in 3.9% and 3.6% of patients, respectively. Indicators of arteriosclerosis, higher pulse wave velocity (PWV), and high pulse pressure were associated with diabetes and particularly with diabetic nephropathy. Patients included due to glomerulonephritis seemed to be at low risk for atherosclerosis and also to show lower levels of hypertension. Conclusions: The difference between causative diseases is associated with different comorbidity and level of arteriosclerosis. Future analysis of the cohort will clarify whether incidence of ESRD and CVD differs among causative diseases. © 2010 Japanese Society of Nephrology. Source

Background: Use of erythropoiesis-stimulating agents (ESA) has been reported to increase the incidence of cardiovascular diseases at target Hb levels by more than 12.0 g/dl. The recent TREAT study found an increased incidence of stroke and cancer when maintaining the Hb level at 12.5 g/dl in diabetic patients. Methods: Surveillance of Epoetin-Adverse Events of Stroke and Cancer (SEASCAN) was a cross-sectional study conducted under urgent conditions by the Committee on CKD Initiatives of the Japanese Society of Nephrology. Patients who were at least 18 years old and had CKD stage 4 and 5, namely, eGFR <30 ml/min/1.73 m2, and who had visited the outpatient department of the participating facilities between December 2009 and January 2010 with at least 6 months of prior medical treatment in the participating facilities were eligible to participate in the study. Results: Of 7,415 patients with CKD stage 4 and 5, 3,653 (49.3%), 879 (11.9%) and 2,883 (38.9%) patients received no epoetin, epoetin for less than 6 months and epoetin for at least 6 months, respectively. In patients who did not use epoetin, use of epoetin for less than 6 months and use of epoetin for at least 6 months, the numbers of patients with stroke were 38 (1.0%), 8 (0.9%) and 27 (0.9%), respectively, and those with newly diagnosed or exacerbated malignancy were 88 (2.4%), 30 (3.4%) and 71 (2.5%), respectively, demonstrating insignificant associations between outcome and duration of treatment with epoetin (P for trend = 0.666 in stroke and 0.836 in malignancy). Conclusions: No significant increase in the risk of developing symptomatic stroke and cancer was observed for the use of epoetin in current clinical practice in Japan. © 2010 Japanese Society of Nephrology.

Background There are currently no prospective, controlled trials of endoscopic transpapillary gallbladder drainage in patients with acute cholecystitis. Objective We evaluated the technical success rate and efficacy of endoscopic transpapillary gallbladder drainage by using either endoscopic nasogallbladder drainage (ENGBD) or endoscopic gallbladder stenting (EGBS) for patients with acute cholecystitis. Design Randomized, controlled study. Setting Tertiary-care referral centers. Patients Seventy-three consecutive patients with acute cholecystitis were randomized. Interventions ENGBD by using a 5F or 7F tube (n = 37) or EGBS (n = 36) by using a 7F stent. Main Outcome and Measurements Technical success, clinical success, adverse events, and procedure-related pain score. Results The overall technical success rates in the ENGBD and EGBS groups were 91.9% and 86.1%, respectively (P >.05). The mean procedure times of ENGBD and EGBS were 20.3 ± 12.1 and 22.2 ± 14.5 minutes, respectively (P >.05). The overall clinical success rates by per protocol analysis were 94.1% and 90.3% in the ENGBD and EGBS groups, respectively, whereas the rates by intention-to-treat analysis were 86.5% and 77.8%, respectively (P >.05). Moderate adverse events were observed in the ENGBD (n = 2) and EGBS (n = 1) groups. The mean visual analog score of postprocedure pain in the ENGBD group was significantly higher than that in the EGBS group (1.3 ± 1.1 vs 0.4 ± 0.8, respectively; P <.001). Limitations Small sample size and the participation of multiple endoscopists who may have different levels of experience in endoscopic transpapillary gallbladder drainage. Conclusions Both ENGBD and EGBS appear to be suitable for the treatment of acute cholecystitis in patients who are poor candidates for emergency cholecystectomy.
