Diagnostic agreement between radiofrequency echographic multispectrometry and dual-energy X-ray absorptiometry in the assessment of osteoporosis in a Polish group of patients.
Osteoporosis is still underdiagnosed in Poland, partly due to limited accessibility to the gold-standard diagnostic technique, that is, dual-energy X-ray absorptiometry (DXA) of the proximal femur and lumbar spine. The use of radiofrequency echographic multispectrometry (REMS) as an alternative diagnostic tool might be of particular interest because this technique is nonionizing, the devices are portable, and their utilization relatively cheap. ⋯ Radiofrequency echographic multispectrometry showed a significant diagnostic agreement with the corresponding DXA measurements. The study further confirms the usefulness of REMS in the assessment of osteoporosis.

Overhydration as a modifiable cardio-vascular risk factor in patients undergoing hemodialysis.
Introduction: Cardiovascular mortality in patients with end-stage renal disease (ESRD) remains high despite advances in dialysis techniques. This can be attributed to several traditional and nontraditional risk factors. Overhydration seems to be one of the promising cardiovascular risk factors that could be targeted to improve survival. Objectives: We aimed to assess the effect of chronic overhydration as well as changes in the degree of overhydration over time on cardiovascular and all-cause morbidity and mortality in patients undergoing hemodialysis. Patients and methods: We enrolled 511 patients with ESRD undergoing hemodialysis. ⋯ Cardiovascular toxicity of overhydration was reflected by elevated levels of N-terminal pro-B-type natriuretic peptide (P <0.001) and cardiac troponin T (P <0.001). Albumin and total cholesterol levels were the lowest in patients with severe overhydration (P <0.001). Mortality was lower in patients with normal hydration status and mild overhydration (P <0.001) as well as in those with stable low or descending overhydration pattern (P = 0.002). Conclusions: We showed that the degree of overhydration is significantly associated with the incidence of cardiovascular complications and prognosis in patients with ESRD undergoing hemodialysis.
