BACKGROUND: Quantitative computed tomography (QCT) biomarkers of airway morphology hold potential for understanding and monitoring regional airway remodeling in asthma. OBJECTIVE: We sought to determine if the change of airway lumen area between TLC and FRC lung volumes measured from CT imaging data was correlated with severe outcomes in asthma patients. METHODS: We studied 152 asthma patients (90 female and 62 male) and 33 normal subjects (12 female and 21 male) with QCT...

Strategies to control the risk domain of NHLBI EPR-3 (National Heart, Lung, and Blood Institute Expert Panel Report-3) asthma guidelines, which includes exacerbations requiring systemic corticosteroids, reduction in lung growth, and progressive loss of lung function, and treatment-related adverse effects, are evolving in children and adolescents. Increasing evidence demonstrates that children and adolescents with asthma are at risk of a reduction in lung growth, leading to lower lung function and potentially chronic obstructive pulmonary disease as adults...

BACKGROUND: Developed countries, such as the USA, have achieved significant decreases in cervical cancer burden since the introduction of Pap smear-based programs in the 1960s. Due to implementation barriers and limited resources, many countries in sub-Saharan Africa (SSA) have been unable to attain such reductions. The purpose of this review is to evaluate implementation strategies used to improve the uptake and sustainability of cervical cancer prevention programs in SSA. METHODS: A reviewer (LJ) independently searched PubMed, Ovid/MEDLINE, Scopus, and Web of Science databases for relevant articles with the following search limits: English language, peer reviewed, and published between 1996 and 2017...

Summary: We present AbDesigner3D, a new tool for identification of optimal immunizing peptides for antibody production using a peptide-based strategy. AbDesigner3D integrates 3D structural data from the Protein Data Bank (PDB) with UniProt data, which includes basic sequence data, post-translational modification sites, SNP occurrences, and more. Other features, such as uniqueness and conservation scores, are calculated based on sequences from UniProt. The 3D visualization capabilities allow an intuitive interface, while an abundance of quantitative output simplifies the process of comparing immunogen peptides...

BACKGROUND: The link between mucus plugs and airflow obstruction has not been established in chronic severe asthma, and the role of eosinophils and their products in mucus plug formation is unknown. METHODS: In clinical studies, we developed and applied a bronchopulmonary segment-based scoring system to quantify mucus plugs on multidetector computed tomography (MDCT) lung scans from 146 subjects with asthma and 22 controls, and analyzed relationships among mucus plug scores, forced expiratory volume in 1 second (FEV1), and airway eosinophils...

BACKGROUND: The Ruth L. Kirschstein Institutional National Research Service Award (T32) provides institutions with financial support to prepare trainees for careers in academic medicine. In 1990, the Cardiac Surgery Branch of the National Heart, Lung and Blood Institute (NHLBI) was replaced by T32 training grants, which became crucial sources of funding for cardiothoracic (CT) surgical research. We hypothesized that T32 grants would be valuable for CT surgery training and yield significant publications and subsequent funding...

OBJECTIVES: We sought to determine the predictive power of metabolic syndrome (MS) definitions on the prognosis in patients with myocardial infarction with ST-segment elevation (STEMI). METHODS: We prospectively included 507 patients with STEMI who were admitted for primary percutaneous coronary intervention and could be identified for MS using the AHA-NHLBI, NCEP-ATP III and IDF definitions. After applying these criteria, we divided the group in patients with MS and without MS; we compared baseline characteristics, clinical findings and outcomes among these patients...

Pathophysiological, epidemiological, and genetic studies provide strong evidence that lipoprotein(a) [Lp(a)] is a causal mediator of cardiovascular disease (CVD) and calcific aortic valve disease (CAVD). Specific therapies to address Lp(a)-mediated CVD and CAVD are in clinical development. Due to knowledge gaps, the National Heart, Lung, and Blood Institute organized a working group that identified challenges in fully understanding the role of Lp(a) in CVD/CAVD. These included the lack of research funding, inadequate experimental models, lack of globally standardized Lp(a) assays, and inadequate understanding of the mechanisms underlying current drug therapies on Lp(a) levels...

RATIONALE: Cystic fibrosis, like primary ciliary dyskinesia, is an autosomal recessive disorder characterized by abnormal mucociliary clearance and obstructive lung disease. We hypothesized that genes underlying the development or function of cilia may modify lung disease severity in persons with cystic fibrosis. OBJECTIVES: To test this hypothesis, we compared variants in 93 candidate genes in both upper and lower tertiles of lung function in a large cohort of children and adults with cystic fibrosis to a population control data set...

BACKGROUND AND OBJECTIVES: Many hospitals require transfusions to be discontinued when vital signs stray from predetermined ranges, regardless of clinical symptoms. Variations in vital signs may be unrelated to transfusion, however, and needlessly stopping a transfusion may delay medical care while increasing donor exposures and healthcare costs. We hypothesized that a detailed study of vital sign changes associated with transfusion of blood product by component, including those associated with potential reactions (complicated) and those deemed to be uncomplicated, would establish a useful framework of reference for treating clinicians and transfusion services alike...

In August 2016, the National Heart, Lung, and Blood Institute (NHLBI) released its Strategic Vision for charting a course for research over the next decade. This vision was the culmination of an unprecedented process that engaged diverse stakeholders from across the United States and around the globe. The process resulted in four mission-oriented goals and eight strategic objectives that provide an overall framework for advancing research in heart, lung, and blood diseases and sleep disorders. In this perspective, we address opportunities that NHLBI has identified to advance late-stage (T4) translation research, implementation science, health inequities research, global health research, and related research workforce development...
