Internal Medicine Faculty Publications

OBJECTIVES: Asthmatics have increased risks of airway-related infections. Little is known about whether this is true for non-airway-related serious infections such as Escherichia coli bloodstream infection (BSI). We assessed whether asthma is associated with a risk of developing community-acquired E coli BSI.

DESIGN: The study was designed as a population-based retrospective case-control study.

SETTING: This population-based study was conducted in Olmsted County, Minnesota.

PARTICIPANTS: The study included 259 all eligible community-acquired E coli BSI cases in Olmsted County, MN between 1998 and 2007 and 259 birthday-matched, gender-matched and residency-matched controls.

PRIMARY AND SECONDARY OUTCOME MEASURES: Only community-acquired E coli BSI …

Exposure To Indoor Biomass Fuel Pollutants And Asthma Prevalence In Southeastern Kentucky: Results From The Burden Of Lung Disease (Bold) Study, Anna C. Barry, David M. Mannino, Claudia Hopenhayn, Heather Bush

David M. Mannino

BACKGROUND:

Asthma is a chronic inflammatory respiratory disease, characterized by episodic and reversible airflow obstruction and airway hyperresponsiveness and is influenced by both genetic and environmental factors.

METHODS:

The Burden of Obstructive Lung Disease (BOLD) survey was used to determine the prevalence of self-reported asthma in a target population of 325,000 adults aged > or =40 in Southeastern Kentucky. Postbronchodilator spirometry was used to classify subjects based on lung function. Risk factors for asthma in this population, in particular indoor usage of biomass fuels, were evaluated.

RESULTS:

The overall study population was comprised of 508 individuals, with 15.5% reporting current asthma …

Association Of Ambient Ozone Exposure With Airway Inflammation And Allergy In Adults With Asthma, Sumita B. Khatri, Fernando C. Holguin, P. Barry Ryan, David M. Mannino, Serpil C. Erzurum, W. Gerald Teague

David M. Mannino

Rationale

Previous studies have demonstrated associations of high ozone levels with increased epidemiologic as well as lung function measures of asthma activity.

Objectives

In an observational study during the summer months, we hypothesized that higher ambient ozone levels are associated with more frequent symptoms, higher airway and systemic inflammation, as well as worse lung function in asthmatics as compared with non-asthmatic individuals.

Methods

Thirty-eight asthmatics and thirteen healthy control subjects residing in metropolitan Atlanta were enrolled during peak ozone season. Medical histories, quality-of-life questionnaires, spirometry, serum immunoglobulin (IgE), peripheral eosinophil counts, and exhaled nitric oxide (NO) were obtained during study …

The Effect Of Sex On Asthma Control From The National Asthma Survey, James Temprano, David M. Mannino

David M. Mannino

Background Previous studies have demonstrated conflicting results with regard to differences in asthma control between the sexes.

Objective We sought to identify sex differences in short-term and long-term measures of asthma control in adults from the National Asthma Survey.

Methods This study analyzed data from the National Asthma Survey (Four-State sample) sponsored by the National Center for Environmental Health, Centers for Disease Control and Prevention. Asthma control was compared between the sexes based on short-term (recent symptoms, asthma attacks, and albuterol use) and long-term (asthma attacks, work days lost, and urgent-care visits and hospitalizations in the prior year) measures. Composite …

Risk Factors For Asthma Incidence: A Review Of Recent Prospective Evidence, M. S. King, David M. Mannino, F. Holguin

David M. Mannino

AIM:

The aim of this study is to determine what factors have been shown, in prospective studies, to predict the incidence of asthma.

METHODS:

We performed a systematic review of peer-reviewed literature from 1994 to 2004 to determine what factors predict the development of asthma in both children and adults. This search strategy yielded 40 studies, with 36 providing some estimate of asthma incidence for the total sample and or a specific subgroup.

RESULTS:

Annual estimated incidence of physician-diagnosed asthma ranged from 0.6 to 29.5 per 1000 persons. Risk factors for incident asthma among children included: male sex, atopic sensitization, …
