The effect of income on selenium intake and status in Utah County, Utah.

Foodstuffs produced and/or purchased locally were analyzed for Se. The effect of income and gender on Se intake and status of Utah County residents was evaluated by measurement of the following indicators: erythrocyte (RBC) and plasma Se concentration, and activity of Se-glutathione peroxidase (Se-GSH-Px) (EC 1.11.1.9) in RBCs, platelets, and plasma. A Random Digit Dialing procedure was employed to stratify subjects according to gender and annual family income (less than +10,000, +10,000-20,000, greater than +20,000) in a 2 x 3 factorial design, seven subjects per cell. The weekly consumption of 44 foods shown to contribute over 90% of the Se intake of U.S. subjects was recorded for each study participant. The estimated minimum daily intake for this sample was 76.0 +/- 4.5 micrograms Se/day (mean +/- SEM). Available grain products are not produced locally, and their Se content is lower than average values reported by the U.S.D.A. Locally produced meat and dairy products had higher than average Se contents. In spite of lower grain Se and higher meat Se concentrations, subjects in this study derived more Se from grain and dairy products, and less from meat products than did subjects in a nationwide sample. The Se status of Utah County residents is similar to several other populations in the United States. There were no significant differences in Se status or intake due to gender or income. The results suggest that consumption of other foods produced in a "high Se" area can maintain Se intake and status in spite of reduced consumption of meat products generally viewed as more reliable sources of dietary Se.

Carbon acquisition and water use in a Northern Utah Juniperus osteosperma (Utah juniper) population.

Water use and carbon acquisition were examined in a northern Utah population of Juniperus osteosperma (Torr.) Little. Leaf-level carbon assimilation, which was greatest in the spring and autumn, was limited by soil water availability. Gas exchange, plant water potential and tissue hydrogen stable isotopic ratio (deltaD) data suggested that plants responded rapidly to summer rain events. Based on a leaf area index of 1.4, leaf-level water use and carbon acquisition scaled to canopy-level means of 0.59 mm day(-1) and 0.13 mol m(-2) ground surface day(-1), respectively. Patterns of soil water potential indicated that J. osteosperma dries the soil from the surface downward to a depth of about 1 m. Hydraulic redistribution is a significant process in soil water dynamics. Eddy covariance data indicated a mean evapotranspiration rate of 0.85 mm day(-1) from March to October 2001, during which period the juniper population at the eddy flux site was a net source of CO2 (3.9 mol m(-2) ground area). We discuss these results in relation to the rapid range expansion of juniper species during the past century.

Incidence of the adult respiratory distress syndrome in the state of Utah.

To determine the incidence of the adult respiratory distress syndrome (ARDS) in Utah, we prospectively screened intensive-care-unit (ICU) patients for ARDS in six of the 40 general acute-care hospitals in Utah. Over a 1-yr period, we diagnosed severe ARDS (oxygenation criterion: PaO2/PAO2 < or = 0.2) in 110 patients. Of these patients, 27 were not residents of Utah. We estimated that there were 58 undetected Utah residents with ARDS in the remaining 34 Utah acute-care hospitals. We also estimated that one Utah resident per year received ARDS care outside Utah. Incorporating these two estimates, we calculated an estimated upper limit for ARDS incidence in Utah of 8.3 ARDS patients per 100,000 total Utah population per year. Using only directly identified Utah residents with ARDS, we calculated the absolute lower limit for ARDS incidence in Utah to be 4.8 ARDS patients per 100,000 Utah population per year. The incidence of ARDS in Utah is about an order of magnitude less than the 1972 National Heart and Lung Institute Task Force estimate of ARDS incidence in the United States, but agrees with more recently published ARDS incidence figures.

Decreasing prevalence of neural tube defects in Utah, 1985-2000.

BACKGROUND: The Utah Birth Defect Network, a statewide surveillance program based in the Utah Department of Health, monitors the occurrence of all neural tube defects (NTDs). Retrospectively and prospectively population-based data was utilized to assess the trend in prevalence for NTDs in Utah from 1985-2000. METHODS: The Utah Birth Defect Network (UBDN) has prospectively identified NTDs in Utah since 1994. NTD cases, including meningomyelocele, meningocele, anencephaly (including exencephaly), encephalocele and craniorachischisis, born to women who are residents of Utah at delivery are reviewed by a pediatric geneticist. All NTDs occurring from 1985-1993 were ascertained retrospectively and documented to be a case. NTDs from all pregnancy outcomes are included (live births, stillbirths and pregnancy terminations) during the entire study period. RESULTS: NTDs in Utah have decreased significantly between 1985-2000 and remain at the lowest prevalence over the last three of those years. The most significant decrease was seen from 1993-2000. The downward trend was demonstrable for anencephaly and meningomyelocele but not for encephalocele. The proportion of NTDs diagnosed prenatally, as well as those pregnancies terminated after prenatal diagnosis have remained constant, without any evidence of an increasing trend since 1990. However, the proportion of pregnancy terminations occurring prior to twenty weeks gestation has increased significantly since 1990. CONCLUSIONS: The reason for the observed decrease is not known but is likely the result of simultaneous prevention activities locally and nationally, the Utah population's propensity for vitamin and supplement consumption, and recent food fortification. The Centers for Disease Control and Prevention recommended in 1992 that all women in their childbearing years take folic acid daily. The Utah Folic Acid Educational Campaign targeted all women of childbearing years beginning in 1996 with this message. Additionally, fortification of grains was voluntary from 1996, became mandatory in 1998 at which point NTD prevalence declined to its lowest level. These factors may have collectively contributed to the reduction observed in NTD prevalence within Utah, demonstrating the positive impact of an important public health endeavor.

Design mediated thrombus reduction in the Utah-100 total artificial heart.

The Utah-100 total artificial heart was initially designed and tested in 1983. General design goals, including improved fit for human application, improved reliability, and elimination of thrombus formation, were identified as improvements over the clinically used Jarvik-7 artificial heart, previously developed at the Institute for Biomedical Engineering, University of Utah. Specific design goals included 1) elimination of connector and valve-associated thrombus formation and 2) elimination of gross mineralization, thrombus formation, and creases on the blood-pumping diaphragm of the device. Explant retrieval results from 29 calves and sheep implanted with the Jarvik-7 artificial heart were compared with results from 25 calves and sheep implanted with the Utah-100 artificial heart. Macroscopic thrombus formation was found in 44% of the connectors of the Jarvik-7 artificial-hearts, compared with 2% (p less than or equal to 0.01) in animals with the Utah-100 artificial heart. Subvalvular and supravalvular thrombi were observed in 33% of the valves in the Jarvik-7 artificial heart and 10% (p less than or equal to 0.01) of the valves in the Utah-100 artificial heart. Mineralization of the pumping diaphragm was observed in 12% of the animals implanted with the Jarvik-7 artificial heart and in 4% of the animals with the Utah-100 diaphragms. Thrombus formation in the diaphragm-housing interface occurred in 2% of Jarvik-7 ventricles and in 6% of the Utah-100 ventricles. There were no identifiable diaphragm creases in the Utah-100 diaphragms, but a 10% incidence was found in Jarvik-7 devices. These results validate substantial progress toward improved design and fabrication methods in the Utah-100 total artificial heart.

Cancer mortality and radioactive fallout in southwestern Utah.

Cancer mortality was compared between a three-county region in southwestern Utah and the remainder of Utah in an investigation of reported excess cancer risks associated with residence in southwestern Utah during the period of above-ground nuclear tests at the Nevada Test Site. Because most of the fallout in southwestern Utah was deposited during 1953-1957, comparisons were limited to persons born before 1958, and deaths from leukemia and bone cancer during 1955-1980 and from other cancers during 1964-1980. There was no excess risk of cancer mortality in southwestern Utah, for single or grouped sites, with the single exception of leukemia which showed statistically significant odds ratios of 1.45 based on 62 deaths at all ages, and 2.84 based on nine deaths at ages 0-14. The finding for childhood leukemia was based on different time periods and geographic comparisons from those of two earlier studies in which no such excess was found. Mortality from all cancer sites combined was significantly lower in southwestern Utah than in the remainder of the state, even after adjustment for the higher proportion of (lower risk) Mormons in southwestern Utah. The present results, including the positive association for leukemia, are inconsistent with the high excess risks reported by Johnson (JAMA 1984;251:230-6) based on an interview survey of cancer incidence among long-term Mormon residents of southwestern Utah.

Activation of the EGF receptor signaling pathway in airway epithelial cells exposed to Utah Valley PM.

Exposure to ambient particulate matter (PM) in the Utah Valley has previously been associated with a variety of adverse health effects. To investigate intracellular signaling mechanisms for pulmonary responses to Utah Valley PM inhalation, human primary airway epithelial cells were exposed to aqueous extracts of PM collected from the year before (Y1), during (Y2), and after (Y3) the closure of a local steel mill located in the Utah Valley in this study. Transfection with kinase-deficient extracellular signal-regulated kinase (ERK) 1 constructs partially blocked Utah Valley PM-induced interleukin (IL)-8 promoter reporter activity. The mitogen-activated protein kinase/ERK kinase (MEK) activity inhibitor PD-98059 significantly abolished IL-8 released in response to Utah Valley PM, as did the epidermal growth factor (EGF) receptor kinase inhibitor AG-1478. Western blotting showed that Utah Valley PM induced phosphorylation of EGF receptor tyrosine, MEK1/2, and ERK1/2, which could be ablated with AG-1478 or PD-98059. For all findings, the potency of Utah Valley PM collected during Y2 was found to be lower relative to that of Y1 and Y3. These data demonstrate that Utah Valley PM can induce IL-8 expression partially through the activation of the EGF receptor signaling.

Respiratory hospital admissions associated with PM10 pollution in Utah, Salt Lake, and Cache Valleys.

This study assessed the association between respiratory hospital admissions and PM10 pollution in Utah, Salt Lake, and Cache valleys during April 1985 through March 1989. Utah and Salt Lake valleys had high levels of PM10 pollution that violated both the annual and 24-h standards issued by the Environmental Protection Agency (EPA). Much lower PM10 levels occurred in the Cache Valley. Utah Valley experienced the intermittent operation of its primary source of PM10 pollution: an integrated steel mill. Bronchitis and asthma admissions for preschool-age children were approximately twice as frequent in Utah Valley when the steel mill was operating versus when it was not. Similar differences were not observed in Salt Lake or Cache valleys. Even though Cache Valley had higher smoking rates and lower temperatures in winter than did Utah Valley, per capita bronchitis and asthma admissions for all ages were approximately twice as high in Utah Valley. During the period when the steel mill was closed, differences in per capita admissions between Utah and Cache valleys narrowed considerably. Regression analysis also demonstrated a statistical association between respiratory hospital admissions and PM10 pollution. The results suggest that PM10 pollution plays a role in the incidence and severity of respiratory disease.

The fall in incidence of prostate carcinoma. On the down side of a prostate specific antigen induced peak in incidence--data from the Utah Cancer Registry.

BACKGROUND: In the 1980s, prostate specific antigen (PSA) came into wide use as a prostate carcinoma screening and detection method in the United States. Following the introduction of PSA, the age-adjusted incidence of prostate carcinoma reported by the Surveillance, Epidemiology, and End Results (SEER) program in the United States rose rapidly (from 84.4/100,000 in 1984 to 163/100,000 in 1991). When an increase in incidence is observed following the introduction of a screening method, a subsequent decrease in incidence may be expected as prevalent cases are removed from the population (a cull effect). Incidence rates may also fall due to factors such as decreased intensity of screening. The Utah Cancer Registry data were examined for a decrease in prostate cancer incidence. METHODS: We tracked age-adjusted prostate carcinoma incidence trends from the population-based Utah Cancer Registry and compared them with rates from the SEER national registry. RESULTS: A rapid and highly correlated rise in prostate carcinoma incidence has been observed in both SEER and Utah incidence rates between 1988 and 1991, the last year for which SEER data are available. In 1992, Utah incidence rates peaked at 236.2 per 100,000. In 1993 and 1994, Utah incidence rates fell to 195.0, and an estimated 164.0 per 100,000, respectively. CONCLUSIONS: Population-based data from the Utah Cancer Registry indicates that the incidence of prostate carcinoma is decreasing rapidly after a similarly rapid increase.

Utah's ban on abortion coverage for low-income women challenged.

On January 30 (1995) two women's health care providers, a rape crisis center, and a YWCA-run battered women's shelter asked the federal district court in Utah to declare invalid and enjoin enforcement of the state's virtual ban on abortion coverage for Medicaid-eligible women. The plaintiffs argue that Utah's criminal prohibition on state Medicaid coverage for abortion--except when the procedure is necessary to prevent a woman's death--violates federal Medicaid law because it does not cover abortions for survivors of rape or incest. The Hyde Amendment has provided federal Medicaid funds for abortions in cases of rape and incest since 1993, and federal courts have since ruled against eight other states that refused to cover those procedures. In late December, Utah was one of seven states notified by the federal Health Care Financing Administration (HCFA) that the state is "out of compliance" with federal Medicaid law. With nearly 46 rapes per 100,000 people, Utah has one of the highest rates of rape in the country. CRLP (Center for Reproductive Law and Policy) has previously filed lawsuits in Utah challenging the state's 1991 abortion ban and a 1993 mandatory delay and biased counseling requirement. Plaintiffs in Utah Women's Clinic v. Graham are represented by CRLP's Eve Gartner, with Salt Lake City attorneys Howard Lundgren and Jeffrey Oritt.

Data, network, and application: technical description of the Utah RODS Winter Olympic Biosurveillance System.

Given the post September 11th climate of possible bioterrorist attacks and the high profile 2002 Winter Olympics in the Salt Lake City, Utah, we challenged ourselves to deploy a computer-based real-time automated biosurveillance system for Utah, the Utah Real-time Outbreak and Disease Surveillance system (Utah RODS), in six weeks using our existing Real-time Outbreak and Disease Surveillance (RODS) architecture. During the Olympics, Utah RODS received real-time HL-7 admission messages from 10 emergency departments and 20 walk-in clinics. It collected free-text chief complaints, categorized them into one of seven prodromes classes using natural language processing, and provided a web interface for real-time display of time series graphs, geographic information system output, outbreak algorithm alerts, and details of the cases. The system detected two possible outbreaks that were dismissed as the natural result of increasing rates of Influenza. Utah RODS allowed us to further understand the complexities underlying the rapid deployment of a RODS-like system.
