Asthma affects approximately 20,383,000 Americans and costs the US $56 billion dollars annually. Asthma burden is not uniform across different racial/ethnic groups. Although annual asthma prevalences ...
Long-term exposure to greenhouse environments exposes greenhouse workers to inhalation of antigens that can cause respiratory diseases. This study was conducted to investigate the prevalence and poten...
Asthma is the most common chronic disease in children, and associations with crowding have been reported. The aim of this study was to explore possible associations of crowding with asthma in children...
To describe the methodology of a randomized controlled trial comparing the efficacy of integrated asthma community health workers (CHW) and a certified asthma educator (AE-C) to improve asthma outcome...
A cross-sectional study in asthma patients to determine if a late age of onset asthma (start symptoms >18 years old), is associated with more persistent airway/systemic inflammation, worse...
This study aims to characterise cough in severe asthma through an observational cross-sectional analysis of patients stratified by inflammatory biomarker profile using a number of subjecti...
Background: Occupational exposures are thought to be responsible for 10-15% of new-onset asthma cases in adults, with disparities across sectors. Because most of the data are derived from ...
This study is a cross-sectional study to evaluate the relationship between coronary calcium score and clinical parameters of asthma such as onset of disease, lung function parameter and ai...
Multinational, multicentre, non-pharmacological intervention, cross-sectional and longitudinal study.
Studies designed to examine associations, commonly, hypothesized causal relations. They are usually concerned with identifying or measuring the effects of risk factors or exposures. The common types of analytic study are CASE-CONTROL STUDIES; COHORT STUDIES; and CROSS-SECTIONAL STUDIES.
Descriptive anatomy based on three-dimensional imaging (IMAGING, THREE-DIMENSIONAL) of the body, organs, and structures using a series of computer multiplane sections, displayed by transverse, coronal, and sagittal analyses. It is essential to accurate interpretation by the radiologist of such techniques as ultrasonic diagnosis, MAGNETIC RESONANCE IMAGING, and computed tomography (TOMOGRAPHY, X-RAY COMPUTED). (From Lane & Sharfaei, Modern Sectional Anatomy, 1992, Preface)
A value equal to the total volume flow divided by the cross-sectional area of the vascular bed.
A microscope with a light source that can be projected into a linear beam. It allows cross-sectional viewing of the AQUEOUS HUMOR; CONJUNCTEIVA; CORNEA; EYELIDS; IRIS; and lens (see LENS, EYE) of the eye.
Studies in which the presence or absence of disease or other health-related variables are determined in each member of the study population or in a representative sample at one particular time. This contrasts with LONGITUDINAL STUDIES which are followed over a period of time.
