Obesity is a well-established risk factor for cardiovascular disease (CVD), but the underweight population of body mass index (BMI) below 18.5 kg/m has not been an object concern. The objective this study to investigate whether could be independent CVD in population-based cross-sectional study.Cross-sectional data 2013 Behavioral Risk Factor Surveillance System (BRFSS) database encompassing 491,773 US adult subjects were used assess CVD. Primary outcomes incidence and relative risks (RRs)...

Administration of autologous mesenchymal stem cells (MSCs) has been shown to improve renal function and histological findings in acute kidney injury (AKI) models. However, its effects chronic disease (CKD) are unclear, particularly the clinical setting. Here, we report our experience with a CKD patient who was treated by intravenous infusion MSCs derived from adipose tissue an unknown clinic outside Korea. The had stable for several years before MSC administration. One week after infusion,...

Background/Aims There may be an association between vitamin D levels and allograft outcomes in kidney transplant recipients (KTRs). However, few studies have been conducted to determine the post-transplant infections. This study investigated impact of deficiency on risk infection after transplantation. Methods We measured 25-hydroxyvitamin (25(OH)D) prior Vitamin was defined as a serum 25(OH)D level < 20 ng/mL. examined incidence various infections during follow-up period. used Cox...

Recurrence of focal segmental glomerulosclerosis (FSGS) is a major therapeutic challenge in kidney transplantation (KT). Although intensive plasmapheresis and high-dose rituximab have been introduced to treat recurrent FSGS, the most effective dosage regimen not determined. Herein we reported first case successful treatment FSGS with low-dose rituximab. The patient showed marked proteinuria (3.5 g/d) oliguria 2 d after KT. Two courses immunoglobulin were applied patient, however, nephrotic...

Background The association of a higher body mass index (BMI) with better survival is well-known "obesity paradox" in patients on hemodialysis (HD). However, men and women have different compositions, which could impact the effect BMI mortality. We investigated gender obesity-mortality relationship Korean HD. Methods This study included 2,833 maintenance HD from multicenter prospective cohort Korea (NCT00931970). between categorized gender-specific mortality was evaluated by an adjusted Cox...

This study analyzed the risk factors for technique survival in dialysis patients and compared rates between hemodialysis (HD) peritoneal (PD) a prospective cohort of Korean patients. A total 1,042 undergoing from September 2008 to June 2011 were analyzed. The modality was defined as that used 90 days after commencing dialysis. Technique two modalities, predictive evaluated. an independent factor survival. PD had higher failure than HD (hazard ratio [HR], 10.8; 95% confidence interval [CI],...

Revascularization is critical for successful ovarian tissue transplantation. Vascular endothelial growth factor (VEGF) and angiopoietin-2 (angpt-2) are the principal mediators of neovascularization. This study was designed to assess VEGF angpt-2 levels in cryopreserved after heterotopic autotransplantation.Ovarian tissues harvested from ICR mice at 5 6 weeks age were stratified as follows: no cryopreservation (controls, group I); vitrification VFS-40 (vitrification, II); gradual freezing...
