INTRODUCTION The objective of this study was to examine the racial disparities in total ankle arthroplasty (TAA) utilization and outcomes. METHODS We used the National Inpatient Sample (NIS) to study the time-trends. Race was categorized as White and Black. Utilization rates were calculated for the U.S. general population per 100,000. Hospital length of stay, discharge disposition and mortali...

The purpose of the study was to examine the cost-effectiveness of managed care interventions with respect to prescriptions for chronic illness sufferers enrolled with a specific medical scheme. The illnesses included, were epilepsy, hypertension, diabetes and asthma. The managed care interventions applied were a primary discount; the use of preferred provider pharmacies, and drug utilization re...

OBJECTIVES/HYPOTHESIS Previous studies showed that chronic rhinosinusitis (CRS) accounts for billions of dollars in healthcare resource utilization. However, all such study estimates of the economic burden of CRS were based on subpopulations in Western societies. This study aimed to investigate differences in the utilization of healthcare services between subjects with CRS and comparison subjec...

Indirect calorimetry and primed constant infusion of [U-13C]glucose were combined in 16 appropriate-for-gestational age newborn, parenterally fed infants, in order to measure glucose utilization and glucose oxidation respectively. Glucose intake ranged between 10.0 and 24.1 g day-1 kg-1 and energy intake between 156.9 and 439.3 kJ day-1 kg-1. Glucose utilization (P less than 0.001), glucose oxi...

Either to sustain autotrophy, or as a prelude to heterotrophy, organic synthesis from an environmentally available C1 feedstock molecule is crucial to the origin of life. Recent findings augment key literature results and suggest that hydrogen cyanide--"Blausäure"--was that feedstock.

Yeasts have been known to humans for thousands of years as they have been used in traditional fermentation processes like wine, beer and bread making. Today, yeasts are also used as alternative sources of high nutritional value proteins, enzymes and vitamins, and have numerous applications in the health food industry as food additives, conditioners and flavouring agents, for the production of m...

The Bacillus subtilis outB gene was found to have strong similarities to an Escherichia coli gene complementing ntr-like mutations in Rhodobacter capsulatus. The deduced gene products had 52% identical amino acids (65% similar residues). The phenotype of strains affected in the OutB function indicates that this B. subtilis gene may be involved in nitrogen utilization.

BACKGROUND Given the high health care utilization, limited evidence for the effectiveness of back pain interventions, and the proliferation of e-mail health discussion groups, this study seeks to determine if the Internet can be used to improve health status and health care utilization for people with chronic back pain. METHODS Randomized controlled trial. Participants included 580 people fro...

BACKGROUND Mental health (MH) comorbidities reduce retention in care for persons living with HIV (PLWH) and are associated with poor health outcomes. Optimizing retention in primary care is vital, as poor retention is associated with delayed receipt of antiretroviral (ARV) therapy, ARV non-adherence, and poor health outcomes, including failure to suppress viral load, decreased CD4 counts, and c...

OBJECTIVE To evaluate the utilization trends of advanced radiology, i.e. computed tomography (CT) and magnetic resonance imaging (MRI), examination in an emergency department (ED) of an academic medical center from 2001 to 2010. PATIENTS AND METHODS We assessed the overall CT and MRI utilization, and the ED patient encounters. Each examination was evaluated according to the patient's age and ...
