Comparing Sociocultural Features of Cholera in Three Endemic African Settings
(Springer Science and Business Media LLC, 2013-09-18)Background Cholera mainly affects developing countries where safe water supply and sanitation infrastructure are often rudimentary. Sub-Saharan Africa is a cholera hotspot. Effective cholera control requires not only a ... -
Comparing the effectiveness of small-particle versus large-particle inhaled corticosteroid in COPD
(Dove Medical Press, 2014)Purpose Small airway changes and dysfunction contribute importantly to airway obstruction in chronic obstructive pulmonary disease (COPD), which is currently treated with inhaled corticosteroids (ICS) and long-acting ... -
Comparing the functional impact of knee replacements in two cohorts
(Springer Science and Business Media LLC, 2014-05-05)Background: To examine if different rates of total knee replacement (TKR) in two similar cohorts with symptomatic knee osteoarthritis (OA) were associated with different functional impact of disease. Methods: Subjects from ... -
Comparing the implementation of team approaches for improving diabetes care in community health centers
(BioMed Central, 2014)Background: Patient panel management and community-based care management may be viable strategies for community health centers to improve the quality of diabetes care for vulnerable patient populations. The objective of ... -
Comparing the SF-12 and SF-36 Health Status Questionnaires in Patients With and Without Obesity
(BioMed Central, 2008)Objective: To assess how well the SF-36, a well-validated generic quality of life (QOL) instrument, compares with its shorter adaptation, the SF-12, in capturing differences in QOL among patients with and without obesity. ... -
Comparison and Optimization of hiPSC Forebrain Cortical Differentiation Protocols
(Public Library of Science, 2014)Several protocols have been developed for human induced pluripotent stem cell neuronal differentiation. We compare several methods for forebrain cortical neuronal differentiation by assessing cell morphology, immunostaining ... -
Comparison between Integrated Backscatter Intravascular Ultrasound and 64-Slice Multi-Detector Row Computed Tomography for Tissue Characterization and Volumetric Assessment of Coronary Plaques
(BioMed Central, 2012)Background: The purpose of this study was to determine the cut-off values of Hounsfield units (HU) for the discrimination of plaque components and to evaluate the feasibility of measurement of the volume of plaque components ... -
Comparison of a Lymph Node Ratio–Based Staging System With the 7th AJCC System for Gastric Cancer
(Ovid Technologies (Wolters Kluwer Health), 2012)OBJECTIVES: The American Joint Committee on Cancer (AJCC) staging system for gastric cancer bases N status on absolute number of metastatic nodes, regardless of the number of examined nodes. We examined a modified staging ... -
A comparison of adipose and bone marrow-derived mesenchymal stromal cell secreted factors in the treatment of systemic inflammation
(BioMed Central, 2014)Background: Bone marrow-derived mesenchymal stromal cells (BMSCs) are a cell population of intense exploration for therapeutic use in inflammatory diseases. Secreted factors released by BMSCs are responsible for the ... -
Comparison of Antidepressant Responses in Patients With Bipolar vs. Unipolar Depression: A Meta-Analytic Review
(Georg Thieme Verlag KG, 2011-01)Background: Since there is considerable uncertainty about therapeutic responses to antidepressants among depressed patients diagnosed with bipolar (BP) vs. unipolar (UP) mood disorders, we have reviewed available studies ... -
Comparison of Apparent Diffusion Coefficient and T2 Relaxation Time Variation Patterns in Assessment of Age and Disc Level Related Intervertebral Disc Changes
(Public Library of Science, 2013)Purpose To compare the variation patterns of ADC and T2 values in different age and intervertebral disc (IVD) levels, thus to identify their sensitivities in assessing age and disc level related IVDs changes. Materials and ... -
Comparison of Approaches for Stroke Prophylaxis in Patients with Non-Valvular Atrial Fibrillation: Network Meta-Analyses of Randomized Controlled Trials
(Public Library of Science, 2016)Background: Multiple novel oral anticoagulants and left atrial appendage closure devices (WATCHMAN) have been tested against dose-adjusted vitamin K antagonists in randomized controlled trials for stroke prophylaxis in ... -
Comparison of arterial and venous blood biomarker levels in chronic obstructive pulmonary disease
(F1000Research, 2013)Purpose: The development of novel biomarkers is an unmet need in chronic obstructive pulmonary disease (COPD). Arterial blood comes directly from the lung and venous blood drains capillary beds of the organ or tissue ... -
Comparison of carnivore, omnivore, and herbivore mammalian genomes with a new leopard assembly
(BioMed Central, 2016)Background: There are three main dietary groups in mammals: carnivores, omnivores, and herbivores. Currently, there is limited comparative genomics insight into the evolution of dietary specializations in mammals. Due to ... -
Comparison of CE-FDG-PET/CT with CE-FDG-PET/MR in the evaluation of osseous metastases in breast cancer patients
(Nature Publishing Group, 2015)Background: Despite improvements in treatments, metastatic breast cancer remains difficult to cure. Bones constitute the most common site of first-time recurrence, occurring in 40–75% of cases. Therefore, evaluation for ... -
