Particulate matter and manganese exposures in Indianapolis, Indiana.

The distribution of PM(2.5) and manganese (Mn) personal exposures was determined over a 4-month period in Indianapolis, IN, at a time when the gasoline additive, methylcyclopentadienyl manganese tricarbonyl (MMT), was not being used. The data collection period coincided with the data collection period in the Toronto, ON, study, where MMT had been used as a gasoline additive for over 20 years. The inferential or target population consisted of noninstitutionalized residents of the Indianapolis area during the monitoring period (from May 1996 through August 1996) who were at least 16 years old. The survey instruments used in this study (and also in Toronto) included a household screener form (HSF), a study questionnaire (SQ), and a time and activity questionnaire (TAQ). The SQ was administered to elicit information about the participant and his/her activities, occupation, and surroundings that might be relevant to his/her exposure to particles and Mn. In addition to the personal particulate matter (PM) and elemental 3-day monitoring, 240 participants completed a TAQ on a daily basis during the actual monitoring period. Also, a subset of participants had 3-day outdoor and indoor stationary monitoring at their home (approximately 58 observations), and sampling was conducted at a fixed site (approximately thirty-three 3-day observations). The quality of data was assessed and compared to the Toronto study in terms of linearity of measurement, instrument and method sensitivity, measurement biases, and measurement reproducibility. Twenty-six of the sample filters were subjected to two analyses to characterize the within-laboratory component of precision in terms of relative standard deviations (RSDs). The median RSD for Mn was 8.7%, as compared to 2.2% for Toronto. The quality assurance (QA) laboratory exhibited a clear positive bias relative to the primary laboratory for Al and Ca, but no systematic difference was evident for Mn. A high interlaboratory correlation (>0.99) was also attained for Mn. Mean field blank results for PM and Mn were 0.87 microg/m(3) and 0.71 ng/m(3), respectively, which were comparable to the Toronto study. The median RSDs for colocated fixed site and residential samples ranged from 2.2% to 9.0% for PM and from 8.8% to 15.3% for Mn, which were close to those observed in Toronto. For the PM(10), the 90th percentile indoors was 124 microg/m(3) compared with 54 microg/m(3) outdoors. This pattern was even more pronounced for the PM(2.5) data (90th percentiles of 92 microg/m(3) indoors vs 30 microg/m(3) outdoors). Personal PM(2.5) was somewhat higher than the indoor levels, but the percentiles seemed to follow the more highly skewed pattern of the indoor distribution. This difference was largely due to the presence of some smokers in the sample; e.g., exclusion of smokers led to a personal exposure distribution that was more similar to the outdoor distribution. The estimated 90th percentile for the nonsmokers' personal exposures to PM was 43 microg/m(3) compared with 84 microg/m(3) for the overall population. In general, the Indianapolis PM levels of a given type and cut size were somewhat higher than the levels observed in Toronto, e.g., the median and 90th percentile for the personal PM(2.5) exposures were 23 and 85 microg/m(3), respectively, in Indianapolis, while in Toronto, the corresponding percentiles were 19 and 63 microg/m(3). The cities' distributions of the proportion of the PM(10) mass in the 2.5-microm fraction appeared similar for the residential outdoor data (medians of 0.67 and 0.65 for Indianapolis and Toronto, respectively, and 90th percentiles of 0.83 for both cities). For the indoor data, Indianapolis tended to have a larger portion of the mass in the fine fraction (median of 0.80 compared to 0.70 for Toronto). Unlike the PM, the Indianapolis indoor Mn concentration levels were substantially lower than the outdoor levels for both PM sizes, and the median personal levels for Mn in PM(2.5) appeared to fall between the median indoor and outdoor levels. The personal Mn exposure distributions exhibited more skewness than the indoor or outdoor distributions (e.g., the means for the personal, indoor, and outdoor distributions were 7.5, 2.6, and 3.5 ng/m(3), respectively, while the medians were 2.8, 2.2, and 3.2 ng/m(3), respectively). At least a substantial portion of the high end of the personal exposure distribution appeared to be associated with occupational exposures to Mn. In general, the Mn levels in both cut sizes in Indianapolis were approximately 5 ng/m(3) smaller than those in Toronto (e.g., the estimated median and mean levels for personal Mn exposures in PM(2.5) were 2.8 and 7.5 ng/m(3), respectively, in Indianapolis, but were 8.0 and 13.1 ng/m(3) in Toronto). For the nonoccupational subgroups with no exposure to smoking and no subway riders in the two cities, the medians (2.6 ng/m(3) in Indianapolis and 7.8 ng/m(3) in Toronto) were similar to those for the overall populations, but the means were substantially smaller (3.1 ng/m(3) in Indianapolis and 9.2 ng/m(3) in Toronto). The median proportion of Mn in the fine fraction (relative to the PM(10) Mn) for Indianapolis was 0.39 for outdoors and 0.55 for indoors; these ratios were somewhat smaller than the corresponding Toronto medians (0.52 and 0.73). The study found high correlations for particulates and Mn between personal exposures and indoor concentrations, and between outdoor and fixed site concentrations, and low correlations of personal and indoor levels with outdoor and fixed site levels. The pattern was similar to that observed for Toronto, but slightly more pronounced. The PM(10) Mn concentrations (log scale) generally exhibited stronger associations among these various measures than the PM(2.5) Mn concentrations. Comparisons of the particulate distributions between PTEAM (Riverside, CA) and the Indianapolis and Toronto studies were also made.

Hemoglobin Indianapolis (beta 112[G14] arginine). An unstable beta-chain variant producing the phenotype of severe beta-thalassemia.

Hemoglobin (Hb) Indianapolis is an extremely labile beta-chain variant, present in such small amounts that it was undetectable by usual techniques. Clinically, it produces the phenotype of severe beta-thalassemia. Biosynthetic studies showed a beta:alpha ratio of 0.5 in reticulocytes and about 1.0 in marrow after a 1-h incubation. These results, similar to those seen in typical heterozygous beta-thalassemia, suggested that betaIndianapolis was destroyed so rapidly that its net synthesis was essentially zero. To examine the kinetics of globin synthesis, reticulocyte incubations of 1.25--20 min were performed with [3H]leucine. The betaIndianapolis:beta A ratio at 1.25 min was 0.80 suggesting that beta Indianapolis was synthesized at a near normal rate. At 20 min, this ratio was 0.46 reflecting rapid turnover of beta Indianapolis. The erythrocyte ghosts from these incubations contained only betaIndianapolis and alpha-chains, and the proportion of betaIndianapolis decreased with time, indicating loss of betaIndianapolis. Pulse-chase studies showed little change in beta A:alpha ratio and decreasing betaIndianapolis:alpha and betaIndianapolis:beta A with time. The half-life of betaIndianapolis in the soluble hemoglobin was approximately equal to 7 min. There was also rapid loss of beta Indianapolis from the erythrocyte membrane. From these results, it may be inferred that betaIndianapolis is rapidly precipitated from the soluble cell phase to the membrane, where it is catabolized. Heterozygotes for beta 0-thalassemia usually have minimal hematologic abnormalities, whereas heterozygotes with betaIndianapolis, having a similar net content of beta-chain, have severe disease. The extremely rapid precipitation and catabolism of betaIndianapolis and the resulting excess of alpha-chains, both causing membrane damage, may be responsible for the severe clinical manifestations associated with this variant. It seems likely that other, similar disturbances in the primary sequence of globin polypeptide chains may produce clinical findings similar to those seen with hemoglobin Indianapolis and thus produce the phenotype of severe beta-thalassemia.

Indianapolis I3: the third generation Integrated Advanced Information Management Systems.

In 2001, the Regenstrief Institute for Health Care and the Indiana University School of Medicine (IUSM) began an IAIMS planning effort to create a vision and a tactical plan for the first Integrated Advanced Information Management Systems (IAIMS) implementation to cross a large area and include unaffiliated institutions. A number of elements made this planning effort unique. Among these elements were the existence of a network infrastructure that supported the Indianapolis Network for Patient Care, the existence of a mature medical informatics program at the Regenstrief Institute, and the existence of a wide-area knowledge network fostered by the IUSM libraries. However, the leadership for a strong information technology role in the IUSM that could promote collaboration in support of education and research across the diverse Indianapolis hospital systems had been lacking. By bringing together various groups, each with a commitment to improve health care quality and public health across the Indianapolis metropolitan area, regardless of individual institutional affiliation, the strategic directions for I3-Indianapolis IAIMS Initiative have been defined and the foundations for a third generation IAIMS construct have been laid in Indianapolis, Indiana.

Emergency medical care for open wheel racing events at Indianapolis Raceway Park.

STUDY OBJECTIVES: To analyze open-wheel racing accidents at Indianapolis Raceway Park during six seasons (1988 through 1993) and describe factors that improve driver safety. DESIGN: Retrospective analysis. SETTING: Indianapolis Raceway Park, a three-track racing facility that includes a 0.686-mile banked, paved, and lighted oval track. PARTICIPANTS: Race drivers in three United States Auto Club racing divisions (Midget, Sprint, and Silver Crown). MEASUREMENTS AND MAIN RESULTS: During 61 open-wheel racing events, 57 drivers were evaluated at Indianapolis Raceway Park after crashes. Eighteen were transferred to Methodist Hospital of Indiana; four drivers required admission two to the ICU. There were no driver deaths. CONCLUSION: Although open-wheel racing is one of the most common forms of motorcar racing, there have been no previously published studies regarding injury patterns or medical care at these events. This study reviewed race driver injuries during six seasons of open-wheel racing at the Indianapolis Raceway Park. During 61 open-wheel racing events, no drivers were killed, but two required intensive care hospitalization.

Seasonality and children's blood lead levels: developing a predictive model using climatic variables and blood lead data from Indianapolis, Indiana, Syracuse, New York, and New Orleans, Louisiana (USA).

On a community basis, urban soil contains a potentially large reservoir of accumulated lead. This study was undertaken to explore the temporal relationship between pediatric blood lead (BPb), weather, soil moisture, and dust in Indianapolis, Indiana; Syracuse, New York; and New Orleans, Louisiana. The Indianapolis, Syracuse, and New Orleans pediatric BPb data were obtained from databases of 15,969, 14,467, and 2,295 screenings, respectively, collected between December 1999 and November 2002, January 1994 and March 1998, and January 1998 and May 2003, respectively. These average monthly child BPb levels were regressed against several independent variables: average monthly soil moisture, particulate matter < 10 microm in diameter (PM10), wind speed, and temperature. Of temporal variation in urban children's BPb, 87% in Indianapolis (R2 = 0.87, p = 0.0004), 61% in Syracuse (R2 = 0.61, p = 0.0012), and 59% in New Orleans (R2 = 0.59, p = 0.0000078) are explained by these variables. A conceptual model of urban Pb poisoning is suggested: When temperature is high and evapotranspiration maximized, soil moisture decreases and soil dust is deposited. Under these combined weather conditions, Pb-enriched PM10 dust disperses in the urban environment and causes elevated Pb dust loading. Thus, seasonal variation of children's Pb exposure is probably caused by inhalation and ingestion of Pb brought about by the effect of weather on soils and the resulting fluctuation in Pb loading.

Potential crashworthiness benefits to general aviation from Indianapolis Motor Speedway technology.

General aviation crashworthiness can potentially benefit from certain advances being accomplished by the automobile industry. Progressive improvements in crash protection technology, as documented by a dramatic reduction in crash injuries and fatalities at the Indianapolis Motor Speedway, reflect improved crashworthiness. The speeds of survivable general aviation aircraft impacts are in the range of the Indianapolis Motor Speedway crashes (200-220 mph). This paper relates the declining crash death rates at Indy by decade versus the increase in speeds. The continuous rise in speeds has prompted the development of new crashworthy designs and driver protection equipment. Crashworthiness improvements include crushable surrounding structures, high-grade restraint systems, protective head gear, fire resistant clothing, break-away structural components, and a "protective cocoon" concept. Adaptation of selected advances in crashworthiness design and operations accomplished at the Indianapolis Motor Speedway to the next generation of general aviation aircraft should provide significant dividends in survival of air crashes.

Incidence of dementia and Alzheimer disease in 2 communities: Yoruba residing in Ibadan, Nigeria, and African Americans residing in Indianapolis, Indiana.

CONTEXT: Alzheimer disease (AD) represents a major and increasing public health problem. If populations were identified with significantly lower or higher incidence rates of AD, the search for risk factors in the genesis of AD could be greatly enhanced. OBJECTIVE: To compare incidence rates of dementia and AD in 2 diverse, elderly community-dwelling populations. DESIGN: The Indianapolis-Ibadan Dementia Project, a longitudinal, prospective population-based study consisting of a baseline survey (1992-1993) and 2 subsequent follow-up waves after 2 years (1994-1995) and 5 years (1997-1998). Each wave followed a 2-stage design, with an in-home screening interview followed by a full diagnostic workup of a subsample of participants based on screening performance. SETTING AND PARTICIPANTS: A total of 2459 community-dwelling Yoruba residents of Ibadan, Nigeria, without dementia, and 2147 community-dwelling African American residents of Indianapolis, Ind, without dementia (all aged 65 years or older). The cohorts were followed up for a mean of 5.1 years and 4.7 years, respectively. MAIN OUTCOME MEASURES: Incident cases of dementia and AD in each of the 2 populations. RESULTS: The age-standardized annual incidence rates were significantly lower among Yoruba than among African Americans for dementia (Yoruba, 1.35% [95% confidence interval [CI], 1.13%-1.56%]; African Americans, 3.24% [95% CI, 2.11%-4.38%]) and for AD (Yoruba, 1.15% [95% CI, 0.96%-1.35%]; African Americans, 2.52% [95% CI, 1.40%-3.64%]). CONCLUSION: This is the first report of incidence rate differences for dementia and AD in studies of 2 populations from nonindustrialized and industrialized countries using identical methods and the same group of investigators in both sites. Further explorations of these population differences may identify potentially modifiable environmental or genetic factors to account for site differences in dementia and AD.

Histoplasmosis in Indianapolis.

Recurrent outbreaks of histoplasmosis in Indianapolis since 1978 have expanded our understanding of histoplasmosis. Histoplasmosis has emerged as the leading opportunistic infection in patients with AIDS from Indianapolis. Clinical manifestations of histoplasmosis are influenced by host factors. Underlying lung disease predisposes to chronic pulmonary histoplasmosis, and immunosuppressive medications or disorders predispose to dissemination. Inflammatory manifestations, including arthritis, erythema nodosum, and pericarditis, commonly occur with acute histoplasmosis. Diagnosis of histoplasmosis requires understanding of the accuracy and limitations of cultural and serological methods. More recently, radioimmunoassay for polysaccharide antigen has offered a new diagnostic approach. Amphotericin B remains the gold standard for treatment and is highly effective, even in immunocompromised individuals. Itraconazole shows promise as an alternative to amphotericin B for treatment of less severely ill patients. The role of fluconazole in therapy remains unknown until ongoing clinical trials are completed. Histoplasmosis cannot be cured in individuals with AIDS and in a small proportion of other individuals with other underlying immunosuppressive conditions. In such cases, long-term maintenance treatment is required to prevent relapse. Antigen detection has proven useful for following progress during treatment and for identifying relapse.

Olestra consumption is not associated with macular pigment optical density in a cross-sectional volunteer sample in Indianapolis.

The associations between the intake of the fat-substitute olestra and the concentrations of macular carotenoid pigments and serum lutein and zeaxanthin were investigated in a volunteer cross-sectional sample in Indianapolis. The study was conducted in January through March, 1998 after olestra-containing savory snacks had been sold in central Indiana for a year. Volunteers (n = 280) aged 18-50 y were recruited to make a single clinic visit during which macular pigment optical density (MPOD) was determined by psychophysical flicker photometry, serum was obtained for determination of lutein and zeaxanthin concentration, usual intake of olestra, carotenoids and nutrients were assessed by 1-y food frequency questionnaire, and health habits including smoking, physical characteristics such as eye color, demographics and medical history were determined by questionnaire. Intake of olestra at least one time per month for the past year was reported by 81:280 subjects and their mean, median and 90(th) percentile intakes were 1.09, 0.34 and 2.43 g olestra/d, respectively. Mean macular pigment optical density was not significantly different between olestra consumers and nonconsumers (0.213 +/- 0.014 vs. 0.211 +/- 0.010) nor was serum lutein and zeaxanthin concentration (0.361 +/- 0.017 vs. 0.375 +/- 0. 013 micromol/L) or intake (1242 +/- 103 mg/d vs. 1042 +/- 58 mg/d) in one-way or two-way ANOVA. Olestra intake was not associated with MPOD or serum lutein and zeaxanthin before or after correction for significant covariates of MPOD. Thus, olestra intake over the past year in a cross-sectional volunteer sample in Indianapolis was not associated with MPOD.

Recurrent urban histoplasmosis, Indianapolis, Indiana, 1980-1981.

In January 1981, informal surveillance of acute histoplasmosis in Indianapolis, Indiana, revealed a marked increase in disease activity for the last quarter of 1980. Fifty-one patients with onset of acute histoplasmosis during this period were identified through review of hospital admissions, emergency room visits, and serologic records at Indianapolis hospitals and the Indiana State Board of Health. In a retrospective case-control study, the authors found a significant association between developing acute histoplasmosis during this period and working or attending classes in a 2 sq mi (5.2 sq km) area encompassing the Indiana University-Purdue University campus (p = 0.015, Fisher's exact test). A review of construction activities on or near the campus during the epidemic period suggested that the probable source of infection was excavation activity for a large new indoor swimming complex (natatorium). Skin tests and serosurveys of students on campus by a newly developed radioimmunoassay for histoplasmal immunoglobulin M antibodies supported the association of infection with exposure to this site (p less than 0.05).

A case of hemoglobin Indianapolis [beta 112(G14) Cys----Arg] in an individual from Cordoba, Spain.

Hemoglobin Indianapolis was first described by Adams et al (1,2) as a very unstable variant with a phenotype similar to severe beta-thalassemia. We have also characterized this variant, but there are several differences in the clinical expression of the variant described in our report and those described in the original case. We found Hb Indianapolis to be unstable, but not to the extent that it could not be detected by routine testing. The four family members heterozygous for the variant were not anemic, showed normal hematologic values, and did not exhibit any severe clinical disadvantages, although there was slight reticulocytosis. The variant could not be resolved from Hb A on cellulose acetate (pH 8.4), but isoelectric focusing showed a double band in the region of Hb A that is probably the variant and Hb A. However, the variant chain was clearly evident by globin chain analyses in acid and alkaline buffers. The condition of additional blood samples did not allow us to determine the oxygen dissociation properties of the variant or the rates of globin chain synthesis.

Hemoglobin Terre Haute arginine beta 106. A posthumous correction to the original structure of hemoglobin Indianapolis.

The initial report of Hb Indianapolis described two affected individuals with the phenotype of severe beta-thalassemia that was dominantly inherited. The structure of this variant could not be deduced by standard techniques because of its extreme instability. Because of this limitation, the structure was ascertained by analysis of the abnormal globin chain, which had been radioactively labeled. These studies strongly suggested that the structure of this variant was cysteine beta 112 to arginine. Subsequent to this report, two additional families with Hb Indianapolis were found. The carriers were minimally affected and the abnormal hemoglobin was only mildly unstable. This major difference in phenotypic expression suggested that further investigation of the original family should be carried out. Unfortunately, both of the original carriers of the variant succumbed to their severe anemia prior to the subsequent reports. However, by the use of the polymerase chain reaction, enough DNA was obtained to sequence the third exon of the beta-globin gene in the original family from the DNA scraped off a 10-year-old bone marrow microscope slide. These studies revealed a substitution of leucine to arginine at position 106 of the beta-globin chain. The polymerase chain reaction results may be consistent with the original protein structural data, if incomplete tryptic cleavage of this arginine residue occurred in the original sample. We have renamed this variant Hb Terre Haute in an attempt to avoid confusion with the Cys beta 112----Arg substitution.

Erythema nodosum in an epidemic of histoplasmosis in Indianapolis.

Eleven patients seen at the Indiana University Medical Center and the Indianapolis Veterans Administration Hospital had erythema nodosum complicating a histoplasmosis infection. A massive, severe outbreak of histoplasmosis occurred in Indianapolis between September 1978 and August 1979. Four hundred thirty-five laboratory-confirmed cases were reported, although serologic findings suggested that from 20,000 to 200,000 persons were actually infected. During this epidemic, 18 (4.1%) of 435 patients were initially seen with erythema nodosum. Ten of 11 patients seen at the Indiana University Medical Center were women, and nine of 11 patients were seen during the first half of the epidemic; race was not a predisposing factor. Seven of 11 patients had respiratory or rheumatologic complaints. None of these 11 patients had evidence of dissemination, died, or required specific antifungal treatment.

The health-care system and African Americans in Indianapolis.

In order to critically assess the health-care system in Indianapolis, it is important to analyze this African-American population from two major perspectives. First, the local African-American population must be viewed in the context of the local health-care system in its present and historical setting. Second, the local African-American population must be viewed in conjunction with other urban African-American populations. These two perspectives will show how the region's economic, social, cultural, and political climate have affected the health-care status of African Americans in Indianapolis.

Investigation of the 1987 Indianapolis Airport Ramada Inn incident.

On October 20, 1987, a military reserve aircraft lost power during a transcontinental flight and attempted an emergency landing at The Indianapolis International Airport. The pilot ejected and the disabled and pilotless aircraft struck a bank building. It then skidded across the street and entered the lobby of The Airport Ramada Inn where it exploded. This incident was unusual in that the fatal injuries occurred in individuals on the ground and not in the occupant of the aircraft. Seven people were killed in the lobby area and two were trapped in a laundry where they died of smoke inhalation. A tenth person died of burns ten days later. Minor injuries were reported among four hotel guests, two firefighters and the Air Force pilot. A multiagency mass disaster-plan had been formulated and rehearsed in preparation for the Panamerican Games, which had been held in Indianapolis in August 1987. A number of volunteers arrived before a security perimeter was established. They began an undocumented removal of the bodies from the scene and were about to remove valuables for "safekeeping" when stopped by coroners' office personnel. Fatalities resulted from smoke inhalation, burns or a combination. Bodies were identified by a combination of dental records, personal effects and visual means within 24 hours. The problems encountered in managing this disaster scene will also be compared with previously reported incidents.

Rheumatologic manifestations of histoplasmosis in the recent Indianapolis epidemic.

Rheumatologic manifestations were noted in 24 (6.3%) of 381 patients with symptomatic histoplasmosis who were seen during a recent epidemic in Indianapolis. Typically, these patients had rapidly additive, rather than migratory, arthritis or arthralgia, which was symmetric in 50%. Ten patients had oligo- or monarticular disease. Knees, ankles, wrists, and small joints of the hand were the most common sites affected. Eleven patients had erythema nodosum. The rheumatologic manifestations were usually mild and, in all but 2 patients, resolved without treatment or with a brief course of nonsteroidal antiinflammatory drugs. The joint disease in patients with erythema nodosum was essentially the same as that seen in patients who did not develop skin lesions. However, those without erythema nodosum more frequently exhibited systemic features, e.g., chills, fever, anemia, and elevated erythrocyte sedimentation rates. Rheumatologic complaints led 16 of the patients in this series (67%) to seek medical attention, and in 3 patients they constituted the sole presenting complaint.

Twenty-first century learning in school systems: the case of the Metropolitan School District of Lawrence Township, Indianapolis, Indiana.

To empower students with skills such as information and technological literacy, global awareness and cultural competence, self-direction, and sound reasoning, teachers must master these skills themselves. This chapter examines how the Digital Age Literacy Initiative of the Metropolitan School District of Lawrence Township in Indianapolis, Indiana, which is funded by the Lilly Endowment, incorporated twenty-first century learning through a systemic approach involving teacher training and the use of data. The authors explain the district's content, process, and context goals toward accomplishing its mission of empowering students with the necessary twenty-first century skills to succeed in the digital age. The district places a strong emphasis on professional development for teachers. To support the necessary teacher learning and therefore sustain the work of the initiative, the district has adopted action research, self-assessment, and an online professional development network. To support teachers in implementing new strategies, master teachers serve as digital age literacy coaches. The chapter discusses the initiative's focus on evidence of progress. Through a partnership with the Metiri Group of California, the district has built a range of assessments including online inventories and twenty-first century skill rubrics. For example, the Mankato Survey collected teacher and student data around access, ability, and use of technology in the classroom in 2001 and then in 2004. This research showed significant gains in some technologies across all grade levels and consistent gains in nearly all technologies for middle and high school students. As it moves into the next phase of implementing the Digital Age Literacy Initiative, the district embraces the systemic shifts in school culture necessary to institutionalize twenty-first century learning.
