Hypothyroidism Induced Severe Rhabdomyolysis in a Hemodialysis Patient
Hypothyroidism occurs relatively common and is a significant cause of morbidity and mortality during the course of chronic kidney disease. Rhabdomyolysis is a potentially life-threatening condition characterised by necrosis of muscular tissue and rarely associates with hypothyroidism. Here we describe a case of rhabdomyolysis due to severe hypothyroidism in a 56-year-old female hemodialysis patient
Magnesium reduces calcification in bovine vascular smooth muscle cells in a dose-dependent manner
WOS: 000300421300010PubMed ID: 21750166Vascular calcification (VC), mainly due to elevated phosphate levels, is one major problem in patients suffering from chronic kidney disease. In clinical studies, an inverse relationship between serum magnesium and VC has been reported. However, there is only few information about the influence of magnesium on calcification on a cellular level available. Therefore, we investigated the effect of magnesium on calcification induced by beta-glycerophosphate (BGP) in bovine vascular smooth muscle cells (BVSMCs). BVSMCs were incubated with calcification media for 14 days while simultaneously increasing the magnesium concentration. Calcium deposition, transdifferentiation of cells and apoptosis were measured applying quantification of calcium, von Kossa and Alizarin red staining, real-time reverse transcription-polymerase chain reaction and annexin V staining, respectively. Calcium deposition in the cells dramatically increased with addition of BGP and could be mostly prevented by co-incubation with magnesium. Higher magnesium levels led to inhibition of BGP-induced alkaline phosphatase activity as well as to a decreased expression of genes associated with the process of transdifferentiation of BVSMCs into osteoblast-like cells. Furthermore, estimated calcium entry into the cells decreased with increasing magnesium concentrations in the media. In addition, higher magnesium concentrations prevented cell damage (apoptosis) induced by BGP as well as progression of already established calcification. Higher magnesium levels prevented BVSMC calcification, inhibited expression of osteogenic proteins, apoptosis and further progression of already established calcification. Thus, magnesium is influencing molecular processes associated with VC and may have the potential to play a role for VC also in clinical situations.Fresenius Medical Care Deutschland GmbH, GermanyThis study was supported by Fresenius Medical Care Deutschland GmbH, Germany
Association of Adiponectin With Body Composition and Mortality in Hemodialysis Patients
BACKGROUND: In the general population, circulating adiponectin is associated with a favorable cardiovascular risk profile (e.g., lower triglycerides and body fat) and decreased mortality. Hemodialysis (HD) patients have comparatively higher adiponectin concentrations, but prior studies examining the adiponectin-mortality association in this population have not accounted for body composition nor shown a consistent relationship. STUDY DESIGN: Prospective cohort study. SETTINGS AND PARTICIPANTS: We examined baseline serum adiponectin concentrations in 501 HD patients across 13 dialysis centers from the prospective MADRAD (Malnutrition, Diet, and Racial Disparities in Chronic Kidney Disease) cohort (entry period 10/2011-2/2013, follow-up through 8/2013). PREDICTOR: Serum adiponectin concentration in tertiles (Tertiles 1, 2, and 3 defined as <=16.1, >16.1ā30.1, >30.1ā100.0 ug/ml, respectively). Adjustment variables included case-mix and laboratory tests (age, sex, race, ethnicity, vintage, diabetes, serum albumin, total iron binding capacity, serum creatinine, white blood cell count, phosphate, hemoglobin, normalized protein catabolic rate), body composition surrogates (subcutaneous, visceral, and total body fat; lean body mass), and serum lipid levels (cholesterol, HDL, triglycerides). OUTCOMES: All-cause mortality using survival (Cox) models incrementally adjusted for case-mix and laboratory tests. RESULTS: Among 501 HD patients, 50 deaths were observed during 631.1 person-years of follow-up time. In case-mixā and laboratory-adjusted Cox analyses, the highest adiponectin tertile was associated with increased mortality vs. the lowest tertile (HR, 3.35; 95% CI, 1.50ā7.47). These associations were robust in analyses that additionally accounted for body composition (HR, 3.18; 95% CI, 1.61ā8.24) and lipids (HR, 3.64; 95% CI, 1.34ā7.58). LIMITATIONS: Residual confounding cannot be excluded. CONCLUSIONS: In conclusion, higher adiponectin is associated with a 3-fold higher death risk in HD patients independent of body composition and lipids. Future studies are needed to elucidate underlying mechanisms, and to determine therapeutic targets associated with improved outcomes in HD patients
Examine Preservice Elementary School Teachers' Perceptions About Soil Science During Community Service Learning
The purpose of this study is to examine preservice elementary school teachers' perceptions about the topic of soil through attending "Soil Science School" as part of the Community Service Practices Course. Qualitative method was used for data analysis. In line with obtained results, it has been observed that the perceptions of preservice electuary school teachers consist of 3 main themes in the form of "Soil Knowledge", Impact of the Soil Science School", "Cooperation of the Faculties of Education and Agriculture".Wo
The impact of strict volume control strategy on patient survival and technique failure in peritoneal dialysis patients
PubMed ID: 21293119Strict volume control strategy provides better cardiac functions and control of hypertension in dialysis patients. We investigated the effect of this strategy on mortality and technique failure in peritoneal dialysis patients over a 10-year period. 243 patients were enrolled. Strict volume control by dietary salt restriction and ultrafiltration was applied. Mean systolic and diastolic blood pressures decreased from 138.4 Ā± 29.9 and 86.3 Ā± 16.8 to 114.9 Ā± 32.3 and 74.7 Ā± 18.3 mm Hg, respectively. Overall and cardiovascular mortality rates were 48.4 and 29.6 per 1,000 patient-years, respectively. In multivariate analysis, age, diabetes and baseline serum albumin level were independent predictors of overall mortality, and age, diabetes and baseline serum calcium of cardiovascular mortality. Residual diuresis and peritoneal equilibration test values were not related to mortality. Strict volume control leads to lower mortality than comparable series in the literature. Technique survival is better during the first 3 years, but not after 5 years. Ā© 2011 S. Karger AG, Basel
