Fatal chlorine gas exposure at a metal recycling facility: Case report.

At least four workers at a metal recycling facility were hospitalized and one died after exposure to chlorine gas when it was accidentally released from an intact, closed-valved cylinder being processed for scrap metal. This unintentional chlorine gas release marks at least the third such incident at a metal recycling facility in the United States since 2010. We describe the fatal case of the worker whose clinical course was consistent with acute respiratory distress syndrome (ARDS) following exposure to high concentrations of chlorine gas. This case report emphasizes the potential risk of chlorine gas exposure to metal recycling workers by accepting and processing intact, closed-valved containers. The metal recycling industry should take steps to increase awareness of this established risk to prevent future chlorine gas releases. Additionally, public health practitioners and clinicians should be aware that metal recycling workers are at risk for chlorine gas exposure.

Health service deficits and school-aged children with asthma: a population-based study using data from the 2007-2008 National Survey of Child Health.

BACKGROUND: Asthma is one of the most common and costly illnesses of childhood. This study addresses health services deficits experienced by school-aged children with asthma. METHODS: Analyzing data from the 2007-2008 National Survey of Child Health, this cross-sectional study used household income, race/ethnicity, and geographic residency as the primary independent variables and health service deficits as the dependent variable. RESULTS: Multivariate analysis yielded that other/multiracial (odds ratio [OR], 1.234; 95% confidence interval [CI], 1.226-1.242) and Hispanic (OR, 2.207; 95% CI, 1.226-1.242) school-aged children with asthma had greater odds of having health services deficits as did both urban (OR, 1.106; 95% CI, 1.099-1.113) and rural (OR, 1.133; 95% CI, 1.124-1.142) school-aged children with asthma. Children with either moderate (OR, 1.195; 95% CI, 1.184-1.207) or mild (OR, 1.445; 95% CI, 1.431-1.459) asthma had greater odds of having a health services deficit than those with severe asthma. Low-income school-aged children with asthma had greater odds of having a health services deficit than high-income children (OR, 1.031; 95% CI, 1.026-1.036). At lesser odds of having a health service deficit were those who were African American, of middle-range income, male, or who were school-aged children with asthma in good to excellent health. CONCLUSION: Both African American and other/multiracial school-aged children were at greater risk of having asthma than either Caucasian or Hispanic children. Three vulnerable subgroups of school-aged children with asthma-rural, Hispanic, and those of low income were the most likely to have health service deficits.

A population-based study of health service deficits for US adults with asthma.

OBJECTIVE: Asthma prevalence in the United States is higher than it is in many other countries and its impact in terms of healthcare expenditures and morbidity and mortality is staggering. In the United States, many groups bear a disproportionate burden of asthma. Understanding the epidemiology of adult asthma and deficits in health care can identify opportunities for improving care and effectively managing resources. METHODS: The computed dependent variable, health service deficits, entails a lack of health insurance, not having a healthcare provider, deferring medical care because of cost, and having had no routine medical exam. Bivariate and multivariate analyses were performed on 2005 Behavioral Risk Factor Surveillance Survey data to examine the relationship between health service deficits experienced by adults with asthma and socioeconomic status (SES), race and ethnicity, and geographic locale. The variable was also calculated for each US state. RESULTS: Hispanic (OR = 1.594, 95% CI = 1.588-1.599) and Other/Multiracial (OR = 1.447, 95% CI = 1.441-1.452) adults with current asthma had greater odds of having a health service deficit. Rural adults with current asthma had greater odds of having a health service deficit (OR = 1.086, 95% CI = 1.083-1.089) when compared with non-rural adult residents. Low-SES (OR = 1.976, 95% CI = 1.971-1.982) and middle-SES (OR = 1.596, 95% CI = 1.592-1.600) adults with current asthma had greater odds of having a health service deficit. The percentage of current asthma adults experiencing at least one health service deficit by state ranged from a low of 28.5% (Delaware) to a high of 58.8% (Wyoming). CONCLUSION: There are clear patterns of disparity associated with health services and asthma that can help target interventions.

Adequacy of diabetes care for older U.S. rural adults: a cross-sectional population based study using 2009 BRFSS data.

BACKGROUND: In the U.S. diabetes prevalence estimates for adults ≥ 65 years exceed 20%. Rural communities have higher proportions of older individuals and health disparities associated with rural residency place rural communities at risk for a higher burden from diabetes. This study examined the adequacy of care received by older rural adults for their diabetes to determine if older rural adults differed in the receipt of adequate diabetes care when compared to their non-rural counterparts. METHODS: Cross-sectional data from the 2009 Behavioral Risk Factor Surveillance Survey were examined using bivariate and multivariate analytical techniques. RESULTS: Logistic regression analysis revealed that older rural adults with diabetes were more likely to receive less than adequate care when compared to their non-rural counterparts (OR = 1.465, 95% CI: 1.454-1.475). Older rural adults receiving less than adequate care for their diabetes were more likely to be: male, non-Caucasian, less educated, unmarried, economically poorer, inactive, a smoker. They were also more likely to: have deferred medical care because of cost, not have a personal health care provider, and not have had a routine medical check-up within the last 12 months. CONCLUSION: There are gaps between what is recommended for diabetes management and the management that older individuals receive. Older adults with diabetes living in rural communities are at greater risk for less than adequate care when compared to their non-rural counterparts. These results suggest the need to develop strategies to improve diabetes care for older adults with diabetes and to target those at highest risk.

Disparities in adult African American women's knowledge of heart attack and stroke symptomatology: an analysis of 2003-2005 Behavioral Risk Factor Surveillance Survey data.

BACKGROUND: Heart disease and stroke are the first and third leading causes of death of American women, respectively. African American women experience a disproportionate burden of these diseases compared with Caucasian women and are also more likely to delay seeking treatment for acute symptoms. As knowledge is a first step in seeking care, this study examined the knowledge of heart attack and stroke symptoms among African American women. METHODS: This was a cross-sectional study analyzing 2003-2005 Behavioral Risk Factor Surveillance Survey (BRFSS) data. A composite heart attack and stroke knowledge score was computed for each respondent from the 13 heart attack and stroke symptom knowledge questions. Multivariate logistic regression was performed using low scores on the heart attack and stroke knowledge questions as the dependent variable. RESULTS: Twenty percent of the respondents were low scorers, and 23.8% were high scorers. Logistic regression analysis showed that adult African American women who earned low scores on the composite heart attack and stroke knowledge questions (range 0-8 points) were more likely to be aged 18-34 (OR = 1.36, CI 1.35, 1.37), be uninsured (OR = 1.32, CI 1.31, 1.33), have an annual household income <$35,000 (OR = 1.46, CI 1.45, 1.47), and have a primary healthcare provider (OR = 1.22, CI 1.20, 1.23). CONCLUSIONS: The findings indicated that knowledge of heart attack and stroke symptoms varied significantly among African American women, depending on socioeconomic variables. Targeting interventions to African American women, particularly those in lower socioeconomic groups, may increase knowledge of heart attack and stroke symptoms, subsequently improving preventive action taken in response to these conditions.

Exposure assessment of young children living in Chicago communities with historic reports of ritualistic use of mercury.

OBJECTIVE: According to a 1997 finding, mercury was available for sale in several Chicago communities for use in spiritual or medicinal practice. Mercury used this way may impact the health of children. The Chicago Department of Public Health (CDPH) and the Centers for Disease Control and Prevention conducted a study to 1) quantify mercury exposure in biological specimens collected from a pediatric clinic or home visit in selected neighborhoods in Chicago, and 2) investigate possible sources of mercury exposure in homes. METHODS: An exposure assessment study design was chosen to determine whether children living in Chicago communities that historically sold mercury were exposed to mercury vapor. We enrolled and collected biological samples from 306 children aged 2-10 years. In addition, we enrolled 42 children during a door-to-door survey of community residents. All the urine samples were analyzed for elemental or inorganic mercury. We also analyzed 43 blood samples to assess dietary mercury. RESULTS: Overall geometric mean urine mercury was 0.26 microg/L. Urine mercury levels did not differ among the three clinics or between the various participant groups. We did not find any association between ritualistic mercury use and exposure to mercury. CONCLUSIONS: Although pediatric mercury exposure does not appear to be problematic among our study population, mercury remains a potential health threat as long as it is readily available in communities. Healthcare providers should be aware of the potential for mercury exposure. Physicians and patients may call the National Poison Control Centers (1-800-222-1222) for information about diagnosis, testing, and treatment for all types of exposures, including exposure to mercury. Professionals are available 24 hours a day.

Vibrio mimicus infection associated with crayfish consumption, Spokane, Washington, 2010.

We report a cluster of severe diarrheal disease caused by Vibrio mimicus infection among four persons who had consumed leftover crayfish the day after a private crayfish boil. Gastrointestinal illness caused by Vibrio mimicus has not been reported previously in Washington State. Three cases were laboratory confirmed by stool culture; using PCR, isolates were found to have ctx genes that encode cholera toxin (CT). Two of the cases were hospitalized under intensive care with a cholera-like illness. The illnesses were most likely caused by cross-contamination of cooked crayfish with uncooked crayfish; however, V. mimicus was not isolated nor were CT genes detected by PCR in leftover samples of frozen crayfish. Clinicians should be aware that V. mimicus can produce CT and that V. mimicus infection can cause severe illness.

Determining an association between having a medical home and uncontrolled asthma in US school-aged children: a population-based study using data from the National Survey of Children's Health.

INTRODUCTION: The American Academy of Pediatrics and the American Academy of Family Physicians believe that infants, children, and adolescents benefit from having a medical home, characterized by accessible, continuous, comprehensive, family-centered, coordinated, compassionate, and culturally effective care. Several studies suggest that patients with asthma benefit from having a medical home. However, no national study has been conducted examining the relationships between having a medical home and asthma control in school-aged children with asthma. The purpose of this study was to examine the hypothesis that having an adequate medical home is protective against uncontrolled asthma in children. METHODS: To test this hypothesis, cross-sectional data from the 2003-2004 National Survey of Children's Health were analyzed. Analyses entailed creating the variables "medical home" as well as "uncontrolled asthma" from multiple variables. Multivariate analysis was performed using children with uncontrolled asthma as the dependent variable. RESULTS: The logistic regression model performed yielded that school-aged children with uncontrolled asthma were more likely to: speak a primary language other than English (OR, 1.069; 95% CI, 1.045-1.093); live in households with incomes<100% of the federal poverty level (FPL) (OR, 1.826; 95% CI, 1.810-1.842); not have health insurance (OR, 2.296; 95% CI, 2.263-2.330); live in rural rather than metropolitan areas (OR, 1.275; 95% CI, 1.262-1.287); and be non-Caucasian (OR, 2.067; 95% CI, 2.050-2.085). Multivariate analysis also yielded that children with uncontrolled asthma were more likely to have a medical home (OR, 1.138; 95% CI, 1.128-1.148). CONCLUSIONS: After controlling for possible confounding variables, this study did not detect an association between having a medical home and asthma control for children with asthma aged 5 to 17 years. Additional research should examine the relationship between variables, such as poverty, place of residence, health insurance status, and the medical home, not only in the instance of uncontrolled asthma, but for other childhood health conditions.

Who is providing and who is getting asthma patient education: an analysis of 2001 National Ambulatory Medical Care Survey data.

Patient education in asthma management is important; however, there is little known about the characteristics of patients receiving asthma education or how often primary care physicians provide it. The objective of the study was to identify the characteristics of patients receiving asthma education. It was a cross-sectional study using 2001 National Ambulatory Medical Care Survey data. The study included 1230 physicians providing office-based ambulatory medical care in the United States. Patients in the study (weighted n=11,279,952) were those diagnosed with asthma based on International Classification of Diseases, 9th Revision code receiving care from a pediatrician, internist or a family physician. Main and secondary outcome measures were asthma education ordered or provided. Multivariate analysis indicated that asthma patients receiving education were more likely to have office visits >20 min [odds ratio (OR) = 3.934], be seen for an acute reason (OR = 2.268), be seen in follow-up rather than an initial visit (OR = 1.780), live in rural rather than metropolitan areas (OR = 1.507), have public rather than private insurance (OR = 1.276) and be seen in privately owned practices (OR = 1.248). Bivariate analyses indicated that patients seeing family physicians were more likely than those seeing internists or pediatricians to receive education. Patient education was not uniformly provided. Family physicians provided more asthma education than either pediatricians or internists. Future research should investigate the quality of education provided.
