RESUMO
INTRODUCTION: This study explored employment trends among working-age patients undergoing hemodialysis using 5-year surveys from 1996 to 2021. Policy changes affecting individuals with disabilities, the economic environment, and employment status among the general population in Japan were considered. Differences in trends by gender and health status were examined. METHODS: Employment status was categorized into employment and nonemployment; and regular, nonregular, and self. Analytical data with similar characteristics were generated over the six surveys using the propensity score method. RESULTS: The employment rate, especially among women, increased from 1996 to 2021. However, the employment rate ratio to the general population was approximately 80% for men and 50% for women, even in 2021. The employment rate increased with an expansion in nonregular employment. Women's employment trends could be explained by changes in real gross domestic product and employment quotas for individuals with disabilities. CONCLUSION: Employment trends differ by gender and by regular versus nonregular employment.

PURPOSE: This study analyzed the influence of financial strains over the life course before initiating hemodialysis on the health outcomes of older Japanese patients. This study was limited to financial strains over the life course before initiating hemodialysis to eliminate the influence of financial strains resulting from resignation from paid jobs. We examined which of the four life course models-pathway, latent, social mobility, and accumulation-were appropriate to describe the influences of financial strains over the life course on older patients' health. PATIENTS AND METHODS: Data were obtained from a cross-sectional survey of 6,644 outpatients in dialysis facilities across Japan. We selected participants aged 60 years and older at the time of the survey. Numbers of dialysis complications, activities of daily living (ADL) disability, and depressive symptoms were selected as health outcomes. Benchmark periods over the life course were constructed in three parts: less than 18 years (childhood), 18-35 years (young adults), and 35-50 years (middle-aged). We retrospectively measured financial strains over the life course. RESULTS: Pathway models best described the influence of financial strains over the life course on the three types of health outcomes. Experiences of financial strains as young adults had a direct influence on ADL disability of older patients. This result supports latent models. Social mobility models (upward and downward mobility) and accumulation models explained the number of dialysis complications, ADL disability, and depressive symptoms in older patients. CONCLUSION: These results suggest that socioeconomic disadvantages over the life course before initiating hemodialysis were significantly associated with health outcomes in older patients.
RESUMO
BACKGROUND: We estimated the flow of endotoxins (ET) from dialysates into the blood of patients on hemodialysis (HD) using limulus amebocyte lysate (LAL) assays and endotoxin activity (EA) determined by neutrophil respiratory burst activity. METHODS: A cross-sectional study compared groups given ultrapure bicarbonate (n = 15; group A), acetate-free bicarbonate dialysates (n = 20; group B) and conventional bicarbonate dialysate (n = 23; group C). A prospective study of group C examined the effect of changing the purity of the dialysate. Biomarkers of inflammation and oxidative stress were measured and ET in blood was assessed by LAL assays and EA. RESULTS: Serum ET levels did not differ among the groups, whereas EA and the biomarkers were significantly increased in group C compared with those in groups A and B. HD using conventional dialysate was independently associated with an increase in EA. Purifying the dialysate significantly decreased EA in group C. CONCLUSION: Measuring EA is useful to assess the influence of dialysate contamination in HD patients.

BACKGROUND AND OBJECTIVES: The present study assesses the effects of the oxidative stress marker, myeloperoxidase (MPO), and the possible MPO-related oxidative stress marker, oxidative alpha(1)-antitrypsin (oxAT), on carotid intima-media thickness (CIMT) and protein-energy wasting (PEW) in patients on hemodialysis (HD). DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Blood samples were obtained from 383 patients before HD to measure WBC count, serum albumin, lipids, high-sensitivity C-reactive protein (CRP), alpha(1)-antitrypsin (AT), interleukin-6, oxidative LDL-C, MPO, and oxAT. We assessed both CIMT and the geriatric nutritional risk index (GNRI) in this cross-sectional competitive study. RESULTS: Levels of MPO and oxAT correlated. Myeloperoxidase was associated with max-CIMT, and oxAT correlated with max-CIMT and GNRI. Multivariate linear regression models showed that MPO and oxAT were independent predictors of increasing max-CIMT, whereas oxAT, but not MPO, independently correlated with GNRI. In four combined MPO and oxAT groups classified according to median values, a multinomial logistic regression model showed that high MPO together with high oxAT was independently associated with increased max-CIMT. Moreover, the OR for max-CIMT with positive PEW and high MPO was significantly increased in the four groups with combined MPO and PEW. CONCLUSIONS: High MPO with high oxAT and high MPO with PEW seem to contribute to plaque formation in patients on HD, whereas elevated MPO or oxAT alone might not predict increasing CIMT. In contrast, a high oxAT value seems to be an independent predictor of PEW in patients on HD.
