Identification of TAP2 protein variants resistant to inhibition by the HSV1 ICP47 protein.

Herpes Simplex Virus 1 evades the host immune system by expressing a protein, ICP47, that binds to and inhibits the heterodimeric Transporter Associated with Antigen Processing (TAP). We screened a library of 1786 variants in TAP2, one of the components of the TAP heterodimer, and identified 39 variants that were resistant to inhibition by ICP47. Of these 39 variants, five were individually tested, and three (T257I, S274H, and T244R) were confirmed to be significantly resistant to inhibition by ICP47.

A Consensus to Revise the Minimum Speech Test Battery-Version 3.

Purpose: The Minimum Speech Test Battery (MSTB) for adults was introduced in 1996 (Nilsson et al., 1996) and subsequently updated in 2011 (Advanced-Bionics et al., 2011).

Thermal tolerance and preference are both consistent with the clinal distribution of house fly proto-Y chromosomes.

Selection pressures can vary within localized areas and across massive geographical scales. Temperature is one of the best studied ecologically variable abiotic factors that can affect selection pressures across multiple spatial scales. Organisms rely on physiological (thermal tolerance) and behavioral (thermal preference) mechanisms to thermoregulate in response to environmental temperature.

Assessment of Reliability and Validity of the Cochlear Implant Skills Review: A New Measure to Evaluate Cochlear Implant Users' Device Skills and Knowledge.

Purpose The Cochlear Implant Skills Review (CISR) was developed as a measure of cochlear implant (CI) users' skills and knowledge regarding device use. This study aimed to determine intra- and interrater reliability and agreement and establish construct validity for the CISR. Method In this study, the CISR was developed and administered to a cohort of 30 adult CI users.

Investigation of an Outcomes-Driven, Computer-Assisted Approach to CI Fitting in Newly Implanted Patients.

Objective: To evaluate the efficacy of outcomes received by newly implanted cochlear implant recipients when an outcomes-driven, computer-assisted approach to cochlear implantation fitting was used. This approach, referred to as "Fitting to Outcome eXpert," or FOX, was developed by Otoconsult in Antwerp, Belgium.

Design: Thirty-one newly implanted subjects participated in a nonrandomized, single-subject, repeated measures design that involved a within-subject comparison of preoperative and postoperative speech recognition scores.

Relevance of Abusive Head Trauma to Intracranial Hemorrhages and Bleeding Disorders.

Background: Bleeding disorders and abusive head trauma (AHT) are associated with intracranial hemorrhage (ICH), including subdural hemorrhage (SDH). Because both conditions often present in young children, the need to screen for bleeding disorders would be better informed by data that include trauma history and are specific to young children. The Universal Data Collection database contains information on ICH in subjects with bleeding disorders, including age and trauma history.

Complications of haemophilia in babies (first two years of life): a report from the Centers for Disease Control and Prevention Universal Data Collection System.

Aim: To describe the prevalence and complications in babies ≤2 years with haemophilia.

Methods: We used a standardized collection tool to obtain consented data on eligible babies aged ≤2 years with haemophilia enrolled in the Centers for Disease Control and Prevention Universal Data Collection System surveillance project at US Hemophilia Treatment Centers (HTCs).

Results: Of 547 babies, 82% had haemophilia A, and 70% were diagnosed within one month of birth.

Hepatitis B vaccination is effective by subcutaneous route in children with bleeding disorders: a universal data collection database analysis.

Subcutaneous (SQ) vs. intramuscular (IM) vaccination may cause fewer injection site complications in children with bleeding disorders, but little is known about comparative immunogenicity. To compare immunogenicity of hepatitis B virus (HBV) vaccination administered SQ or IM to individuals <2 years old with bleeding disorders, we performed a retrospective analysis of HBV surface antibody titres among patients enrolled in the universal data collection database who had received three doses of HBV vaccine solely by one route (SQ or IM).

Providing young women with credible health information about bleeding disorders.

Background: Approximately 1% of U.S. women may have an undiagnosed bleeding disorder, which can diminish quality of life and lead to life-threatening complications during menstruation, childbirth, and surgery.

Increased prevalence of inhibitors in Hispanic patients with severe haemophilia A enrolled in the Universal Data Collection database.

Neutralizing inhibitors develop in 20-30% of patients with severe factor VIII (FVIII) deficiency. It is well established that Blacks have a higher prevalence of inhibitors than Whites. This is the first study to definitively demonstrate increased inhibitor prevalence in the Hispanic population.

Insurance, home therapy, and prophylaxis in U.S. youth with severe hemophilia.

Background: Home infusion therapy, particularly on a prophylactic regimen, is linked with reduced morbidity among youth with severe hemophilia. However, the association of insurance coverage with these home therapies is unknown.

Purpose: This study explores the connections among insurance, home infusion therapy, and prophylaxis treatment in a nationwide cohort of 3380 boys and young men (aged 2 to 20 years) with severe hemophilia.

Associations between intracranial haemorrhage and prescribed prophylaxis in a large cohort of haemophilia patients in the United States.

Intracranial haemorrhage (ICH) is the most serious type of bleeding for patients with haemophilia. Prior published reports regarding ICH predate the widespread provision of prophylaxis. Our study objectives were to determine risk factors for ICH and whether prophylaxis reduces ICH occurrence.

Hypoalbuminemia predicts acute stroke mortality: Paul Coverdell Georgia Stroke Registry.

Background: Mortality remains unacceptably high among patients hospitalized for acute stroke. Additional knowledge about factors that contribute to mortality after stroke is important for instituting therapies to lower mortality. We sought to determine the factors that predict mortality in patients hospitalized for acute stroke.

The head problem. The organizational significance of segmentation in head development.

This review argues for the segmental basis of chordate head organization which, like somite-based segmental organization in the trunk, takes its origin from early mesodermal development. The review builds on, and brings up to date, Goodrich's well-known scheme of head organization. It surveys recent data in support of this scheme and shows how evidence and arguments supposedly in conflict with it can be accommodated.

Sites of initial bleeding episodes, mode of delivery and age of diagnosis in babies with haemophilia diagnosed before the age of 2 years: a report from The Centers for Disease Control and Prevention's (CDC) Universal Data Collection (UDC) project.

Lack of detailed natural history and outcomes data for neonates and toddlers with haemophilia hampers the provision of optimal management of the disorder. We report an analysis of prospective data collected from 580 neonates and toddlers aged 0-2 years with haemophilia enrolled in the Universal Data Collection (UDC) surveillance project of the Centers for Disease Control and Prevention (CDC). This study focuses on a cohort of babies with haemophilia whose diagnosis was established before the age of two.

Neighborhood poverty and racial differences in ESRD incidence.

Poverty is associated with increased risk of ESRD, but its contribution to observed racial differences in disease incidence is not well-defined. To explore the contribution of neighborhood poverty to racial disparity in ESRD incidence, we analyzed a combination of US Census and ESRD Network 6 data comprising 34,767 patients that initiated dialysis in Georgia, North Carolina, or South Carolina between January 1998 and December 2002. Census tracts were used as the geographic units of analysis, and the proportion of the census tract population living below the poverty level was our measure of neighborhood poverty.

Clinical characteristics of patients with early hospital arrival after stroke symptom onset.

Background: Identifying characteristics of early arrivers after stroke may be useful to improve delivery of acute stroke treatment. We sought to identify the clinical characteristics and outcomes of patients with ischemic stroke who present early after symptom onset using data collected from a representative sample of hospitals in the state of Georgia.

Methods: Data were obtained retrospectively from a statewide observational stroke registry from December 1, 2001, to February 28, 2002, and from February 1 to March 31, 2003.

Predictors of improved HbA1c testing by primary care physicians.

Measurement of glycosylated hemoglobin (HbA1c) among patients with diabetes mellitus contributes to attaining control of blood glucose, which in turn is associated with fewer complications. Here, we seek to identify physician and county level characteristics that predict increased HbA1c testing among Medicare beneficiaries with diabetes who did not have testing in the baseline year. Physicians in counties with more people on Medicaid, or with fewer physicians per capita tended to have less improvement in HbA1c testing among Medicare beneficiaries over the three year study period.

Medicare patients with cardiovascular disease have a high prevalence of chronic kidney disease and a high rate of progression to end-stage renal disease.

The risk of progression to ESRD among individuals with cardiovascular disease and chronic kidney disease (CKD) is not well defined. The purpose of this study was to describe the risk of ESRD among patients with cardiovascular disease. Charts were abstracted for randomly selected hospitalized Medicare beneficiaries with a diagnosis of either congestive heart failure (CHF) or acute myocardial infarction (AMI).

Intrathecal ziconotide in the treatment of refractory pain in patients with cancer or AIDS: a randomized controlled trial.

Context: Ziconotide (formerly SNX-111) selectively blocks N-type voltage-sensitive calcium channels and may be effective in patients with pain that is refractory to opioid therapy or those with intolerable opioid-related adverse effects.

Objective: To assess the safety and efficacy of intrathecal ziconotide in patients with pain that is refractory to conventional treatment.

Design, Setting, And Patients: Double-blind, placebo-controlled, randomized trial conducted from March 12, 1996, to July 11, 1998, at 32 study centers in the United States, Australia, and the Netherlands.

Improved diabetes care by primary care physicians: results of a group-randomized evaluation of the Medicare Health Care Quality Improvement Program (HCQIP).

Background/objectives: Glycosylated hemoglobin (HbA1C) measurements in patients with diabetes mellitus contribute to glycemic control, and, therefore to lower diabetic complication rates. Determine if an intervention that includes claims-based feedback about patterns of HbA1C measurement results in more frequent monitoring of HbA1C in diabetic Medicare beneficiaries.

Subjects: Primary care physicians in a single Southern state treating Medicare beneficiaries with diabetes mellitus.

Renal insufficiency and anemia are independent risk factors for death among patients with acute myocardial infarction.

Background: Chronic kidney disease (CKD) increases risk of death among patients with coronary artery disease. Mortality risks associated with CKD among patients with cardiovascular disease (CVD) are not well defined. Anemia is associated with increased mortality in end-stage renal disease (ESRD) patients and may also increase risk among patients with CVD.

Administrative data as a tool for arthritis surveillance: estimating prevalence and utilization of services.

The public health burden of arthritis and related conditions is incompletely described by commonly used public health surveillance systems. We examined the potential of administrative data as a supplement. The administrative data sources we used underestimated the prevalence of arthritis and overestimated service utilization for persons with arthritis when data from only one year were used.

Anemia and renal insufficiency are independent risk factors for death among patients with congestive heart failure admitted to community hospitals: a population-based study.

The purpose of this retrospective cohort study was to examine the associations among chronic kidney disease, anemia, and risk of death among patients with heart failure. Retrospective cohort study. Patients with a principal diagnosis of heart failure (ICD9 codes 402.
