Patients' and family members' perspectives on arrhythmias and sudden death in dialysis: the HeartLink focus groups pilot study.

Background: Patients receiving dialysis face a high risk of cardiovascular disease, arrhythmia and sudden cardiac death. Few patients, however, are aware of this risk. Implantable cardiac monitors are currently available for clinical use and can continuously monitor cardiac rhythms without the need for transvenous leads.

Sociodemographic and Kidney Disease Correlates of Nutrient Intakes Among Urban African Americans With Uncontrolled Hypertension.

Objective: The objective of this study was to determine the association between sociodemographic factors and intakes of 4 nutrients and associations between intakes and markers of kidney disease to identify opportunities to improve outcomes among clinically high-risk African Americans.

Design And Methods: We conducted a cross-sectional study of baseline data from the Achieving Blood Pressure Control Together study, a randomized controlled trial of 159 African Americans (117 females) with uncontrolled hypertension in Baltimore MD. To determine the association between sociodemographic factors and nutrient intakes, we constructed linear and logistic regression models.

Pilot Intervention Addressing Social Support and Functioning of Low Socioeconomic Status Older Adults With ESRD: The Seniors Optimizing Community Integration to Advance Better Living with ESRD (SOCIABLE) Study.

Rationale & Objective: Older adults with end-stage kidney disease have increased morbidity, fatigue, and decreased physical function, which can inhibit self-care and social engagement. We pilot tested a home-based program to improve physical and social functioning of low socioeconomic status older adults treated with hemodialysis (HD).

Study Design: Qualitative study and randomized waitlist control intervention.

Perceived barriers and facilitators of using dietary modification for CKD prevention among African Americans of low socioeconomic status: a qualitative study.

Background: Factors influencing the use of dietary interventions for modification of CKD risk among African Americans have not been well-explored. We assessed perceived barriers and facilitators of CKD prevention through dietary modifications among African Americans with low socioeconomic status (SES) and at high risk for CKD.

Methods: We conducted a qualitative study involving three 90 minute focus groups of low SES (limited education, unemployed, uninsured, or income<$25,000/year) African American residents of Baltimore, Maryland (N=17), who were aged 18-60 years, with no known history of CKD and (1) a family history of end stage renal disease and (2) self-reported diabetes, hypertension, cardiovascular disease, HIV or obesity.

Feasibility and acceptability of the TALK social worker intervention to improve live kidney transplantation.

Live kidney transplantation (LKT) is underused by patients with end-stage renal disease. Easily implementable and effective interventions to improve patients' early consideration of LKT are needed. The Talking About Live Kidney Donation (TALK) social worker intervention (SWI) improved consideration and pursuit of LKT among patients with progressive chronic kidney disease in a recent randomized controlled trial: Patients and their families were invited to meet twice with a social worker to discuss their self-identified barriers to seeking LKT and to identify solutions to barriers.

Superconductivity of metallic boron in MgB2.

Boron in MgB2 forms stacks of honeycomb layers with magnesium as a space filler. Band structure calculations indicate that Mg is substantially ionized, and the bands at the Fermi level derive mainly from B orbitals. Strong bonding with an ionic component and considerable metallic density of states yield a sizable electron-phonon coupling.

Calculation of polarization using a density functional method with localized charge.

A density functional method, which represents the total charge density as a sum of self-consistently determined localized densities, is described. While this approach is generally less accurate than conventional band-structure methods, it offers a relatively simple interpretation of polarization and related properties. The method is illustrated with results for NaCl, MgO, and AlP.
