Validation of a New Physical Activity Instrument Against Pedometers Among Dialysis Patients

The newly developed Low Physical Activity Questionnaire (LoPAQ) was designed to capture the low activity level among typically sedentary patients undergoing dialysis and correlated well with a physical activity questionnaire used in the general population. However, this instrument has not been validated against a more objective measure.

Rationale: Low physical activity is frequent in end stage renal disease. We evaluated the longitudinal change in physical activity and its barriers in hemodialysis (HD) patients and the association between the patterns of physical activity change, body composition, and beta-aminoisobutyric acid (BAIBA), as circulating myokine. Methods: This is an observational study where HD patients were considered in a 24-month follow-up. We assessed overtime the change of physical inactivity and its barriers by validated questionnaires, body composition by bioimpedance analysis, muscle strength by hand-dynamometer, and plasma BAIBA le...

Infected arteriovenous grafts necessitate intervention to obtain source control. However, excising the graft material can be challenging and can lead to complications. Leaving a cuff of graft at the sites of anastomosis allows for the avoidance of potential risks. However, it is unclear whether doing so places patients at risk of recurrent graft infection. The purpose of the present study was to investigate the effect of complete vs partial excision of infected arteriovenous prosthetic dialysis access grafts.

Prognostic value of N-terminal fragment of the prohormone brain-type natriuretic peptide (NT-proBNP) was analyzed in patients with multiple myeloma complicated by dialysisdependent renal failure. The prospective study included 20 patients with newly diagnosed multiple myeloma. The concentrations of NT-proBNP were measured before antimyeloma chemotherapy. The median age of the patients was 67 (63-76) years. The median glomerular filtration rate was 4 (4, 5) ml/min/1.73 m2. For overall survival, the area under ROC curve was 0.75 and the cut-off point was 7000 pg/ml. At median follow-up of 17.3 months, the overall survival wa...

AbstractAcute blood purification therapy is an essential artificial organ in critical care. In the review article, looking back on the history, we describe our present knowledge and techniques of acute blood purification therapy in critical care. The topics include continuous hemodiafiltration (CHDF), online HDF as an artificial liver support, blood purification therapy aiming to remove pathogenic substances of sepsis, a procedure for connecting a CRRT device into an extra-corporeal membrane oxygenation circuit, and replacement fluid for CHDF. We also raise remaining issues and clarify the future direction of acute blood p...

Authors: Niyyar VD Abstract Sonography is increasingly being used by nephrologists and the field of dialysis access is no exception. Advances in technology have allowed the addition of this universally available, portable, non-invasive tool to the nephrologist's armamentarium, which provides information on both morphology and physiology without the need for contrast or radiation. Ultrasound may be used across the spectrum of dialysis access, including central venous catheter placements, vascular mapping, regional anesthesia, creation, maintenance and assessment of hemodialysis access as well as assessment of the ab...

ien-Cheng Huang Physicians experience high stress and have much responsibility during a night shift, which contributes to increased sympathetic activity, the risk factor for renal disease. The risk for end-stage renal disease (ESRD) in physicians is still unclear. Therefore, we conducted a nationwide population-based cohort study to clarify this issue. Using Taiwan’s National Health Insurance Research Database, we identified 30,268 physicians and 60,536 individuals from the general population matched with a ratio of 1:2 by age and sex. All participants who had ESRD before 2006 and residents were excluded. ESR...

AbstractPurpose of ReviewNon-dialysis-dependent chronic kidney disease (NDD-CKD) patients are at an increased risk of cardiovascular disease (CVD) –related deaths in comparison with the general population. This review summarizes recent guideline recommendations and studies on primary and secondary prevention of traditional cardiovascular (CV) risk factors in those with NDD-CKD.Recent FindingsThe use of antiplatelet agents for primary prevention in CKD is not supported by clinical trial evidence; however, they offer potential benefits when used for secondary prevention of CVD in the absence of an elevated bleeding ris...
