Testing of the therapeutic efficacy and safety of AMPA receptor RNA aptamers in an ALS mouse model.

In motor neurons of sporadic amyotrophic lateral sclerosis (ALS) patients, the RNA editing at the glutamine/arginine site of the GluA2 subunit of α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptors is defective or incomplete. As a result, AMPA receptors containing the abnormally expressed, unedited isoform of GluA2 are highly Ca-permeable, and are responsible for mediating abnormal Ca influx, thereby triggering motor neuron degeneration and cell death. Thus, blocking the AMPA receptor-mediated, abnormal Ca influx is a potential therapeutic strategy for treatment of sporadic ALS.

Enhancing transient protein expression in HEK-293 cells by briefly exposing the culture to DMSO.

Background: Transient expression of proteins in mammalian cells is a key technique for many functional and structural studies of human and higher eukaryotic genes as well as for the production of recombinant protein therapeutics. Maximizing the expression efficiency to achieve a higher expression yield is desirable and may be even critical when, for instance, an expressed protein must be characterized at the single-cell level.

New Methods: Our goal was to develop a simple method by which protein expression yield in human embryonic kidney (HEK)-293 cells could be enhanced with a brief treatment of dimethyl sulfoxide (DMSO) solution.

A kainate receptor-selective RNA aptamer.

Kainate and α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors are two major, closely related receptor subtypes in the glutamate ion channel family. Excessive activities of these receptors have been implicated in a number of central nervous system diseases. Designing potent and selective antagonists of these receptors, especially of kainate receptors, is useful for developing potential treatment strategies for these neurological diseases.

Fostering Interprofessional Education Through a Multidisciplinary, Community-Based Pandemic Mass Vaccination Exercise.

We expanded health care services to economically disadvantaged individuals in an interprofessional, student-driven vaccination effort that also served as a pandemic planning drill. Health care professional students from colleges in and around Rockford, Illinois participated in implementing a mass vaccination event from 2011 to 2014 that targeted the underserved population. There was a 459% increase in total vaccinations administered to at-risk patients from year 1 to year 4.

A Peer-to-Peer Mentoring Program for In-Center Hemodialysis: A Patient-Centered Quality Improvement Program.

A patient-centered quality improvement program implemented in one Virginia hemodialysis facility sought to determine if peer-to-peer (P2P) programs can assist patients on in-center hemodialysis with self-management and improve outcomes. Using a single-arm, repeatedmeasurement, quasi-experimental design, 46 patients participated in a four-month P2P intervention. Outcomes include knowledge, self-management behaviors, and psychosocial health indicators: self-efficacy, perceived social support, hemodialysis social support, and healthrelated quality of life (HRQoL).

mutation associated with pseudorheumatoid dysplasia.

Progressive pseudorheumatoid dysplasia (PPD) is a skeletal dysplasia characterized by predominant involvement of articular cartilage with progressive joint stiffness. Here we report genetic characterization of a consanguineous family segregating an uncharacterized from of skeletal dysplasia. Whole-exome sequencing of four affected siblings and their parents identified a loss-of-function homozygous mutation in the gene, leading to diagnosis of PPD in the affected individuals.

Right TraC™ Post-Hospitalization Care Transitions Program to Reduce Readmissions for Hemodialysis Patients.

Background: Hemodialysis (HD) patients have high hospitalization rates. This nonrandomized trial tested the effect of a bundle of renal-specific "Right TraC™" strategies on 30-day all-cause readmission rates and, secondarily, 90-day readmissions and overall admissions among HD patients.

Methods: Twenty-six Fresenius clinics in West Virginia, Ohio, and Kentucky participated in the interventions.

Association of AHSG with alopecia and mental retardation (APMR) syndrome.

Alopecia with mental retardation syndrome (APMR) is a very rare autosomal recessive condition that is associated with total or partial absence of hair from the scalp and other parts of the body as well as variable intellectual disability. Here we present whole-exome sequencing results of a large consanguineous family segregating APMR syndrome with seven affected family members. Our study revealed a novel predicted pathogenic, homozygous missense mutation in the AHSG (OMIM 138680) gene (AHSG: NM_001622:exon7:c.

Integrating Preventive Cardiovascular Healthcare Into Home Health: A Pilot Study.

The viability of measuring and integrating preventive cardiovascular care into home healthcare was investigated through a pilot study fielded during 2013 and 2014. The study tested the feasibility of using a data registry to measure preventive cardiovascular care delivered in home healthcare, examined opportunities for quality improvement, and looked at the association between exposure to evidence-based tools and improvement in aspirin use and blood pressure screening and control among a convenience sample of 20 agencies. Based on promising results, the home healthcare cardiovascular quality initiative continues in alignment with Million Hearts® and offers tools that clinicians can use to understand the risks for heart attack and stroke within their agency's population of patients and respond with best practices.

Making a Dent in Undiagnosed and Untreated Depression among Older West Virginians.

Importance: Depression, a serious and debilitating disease, remains under-diagnosed and inadequately treated among older adults.

Objective: To describe the prevalence of depression among older West Virginians and report the extent to which primary care providers screen Medicare beneficiaries for depression.

Methodology: Descriptive analysis using 2014 Behavioral Risk Factor Surveillance System to estimate depression prevalence; Medicare Part B claims, 2012 - 2014, to measure depression screening.

Pre-ESRD Care and Mortality in Incident ESRD Patients With Multiple Myeloma.

Objectives: The relationship between mortality and pre-ESRD (end-stage renal disease) nephrology care in incident ESRD patients with multiple myeloma (MM) as the primary cause of renal failure has not been examined.

Materials And Methods: Among 439,206 incident US hemodialysis patients with MM as the primary cause of ESRD (June 1, 2005 to May 31, 2009) identified using the US Renal Data System, adjusted odds ratios (OR) for reported pre-ESRD nephrology care for ESRD due to MM (n=4561) versus other causes (n=434,645) were calculated. The association of pre-ESRD nephrology care with subsequent mortality in MM-ESRD patients was examined.

Correlates of change in health care worker seasonal influenza vaccination rates among dialysis facilities.

We conducted a campaign to increase seasonal influenza vaccination of dialysis health care workers (HCWs) in the District of Columbia, Maryland, Virginia, and West Virginia. Between the 2010-2011 and 2011-2012 influenza seasons we examined the correlates of change. HCW vaccination rates improved significantly (P < .

Exploratory analysis of the relationship between home health agency engagement in a national campaign and reduction in acute care hospitalization in US home care patients.

Rationale, Aims And Objectives: To determine whether US home health agencies that intensively engaged with the 2010 Home Health Quality Improvement National Campaign were more likely to reduce acute care hospitalization (ACH) rates than less engaged agencies.

Method: We included all Medicare-certified agencies that accessed Campaign resources in the first month of the Campaign and also responded to an online survey of resource utilization at month two. We used the survey data and item response theory to estimate a latent construct we called engagement with the campaign.

High one year mortality in adults with sickle cell disease and end-stage renal disease.

Adequate pre-dialysis care reduces mortality among end-stage renal disease (ESRD) patients. We tested the hypothesis that individuals with ESRD due to sickle cell disease (SCD-ESRD) receiving pre-ESRD care have lower mortality compared to individuals without pre-ESRD care. We examined the association between mortality and pre-ESRD care in incident SCD-ESRD patients who started haemodialysis between 1 June, 2005 and 31 May, 2009 using data provided by the Centers for Medicare and Medicaid Services (CMS).

Prevalence of arteriovenous fistulas in incident hemodialysis patients: correlation with patient factors that may be associated with maturation failure.

Background: Lok et al previously reported a risk equation for arteriovenous fistula (AVF) maturation failure. It is unclear whether this model or a more comprehensive model correlates with incident AVF use in the US hemodialysis population.

Study Design: Cross-sectional study.

Achieving the goal: results from the Fistula First Breakthrough Initiative.

Purpose Of Review: This review summarizes the background and implementation of the Fistula First Breakthrough Initiative (FFBI), published information about changes in vascular access practice since its inception, and several issues raised by the program.

Recent Findings: The FFBI is a surveillance system using the End-Stage Renal Disease (ESRD) Networks to spread improvement ideas. Concomitant with implementation of the program, prevalent arteriovenous fistula use has increased an average of 3.

Achieving the goal of the Fistula First breakthrough initiative for prevalent maintenance hemodialysis patients.

Background: The Centers for Medicare & Medicaid Services (CMS) established a national goal of 66% arteriovenous fistula (AVF) use in prevalent hemodialysis (HD) patients for the current Fistula First Breakthrough Initiative. The feasibility of achieving the goal has been debated. We examined contemporary patterns of AVF use in prevalent patients to assess the potential for attaining the goal by dialysis facilities and their associated End-Stage Renal Disease Networks in the United States.

Improving influenza vaccination in dialysis facilities.

The End-Stage Renal Disease Network 5 sought to improve the influenza vaccination rate for the period September 1, 2008, to January 31, 2009, through an awareness campaign, coupled with primary data collection in the form of a tracking tool prepopulated with patient names. The latter served as a reminder to staff to determine the immunization status of patients and offer the influenza vaccination, as appropriate. Targets for the intervention were all facilities and their prevalent hemodialysis and peritoneal dialysis patients, with the exclusion of military treatment centers, Veterans Health Administration hospitals, and prisons.

A statewide collaborative initiative to improve the quality of care for patients with acute myocardial infarction and heart failure.
