Surface-specific fall injury rates on Utah school playgrounds.

The purpose of this study was to estimate surface-specific rates of fall injuries on school playgrounds. Playground injuries related to falls from climbing equipment and the surfaces involved were identified from injury reports for 1988 to 1990 from 157 Utah elementary schools. Enrollment data and playground inspections were used to estimate student-years spent over each surface. The fall injury rates per 10,000 student-years were asphalt, 44; grass, 12; mats, 16; gravel, 15; and sand, 7. These data did not show that impact-absorbing surfaces reduce fall injuries on playgrounds better than grass. Improved field studies are needed to guide policy decisions for playground surfacing.

Volunteer revegetation of waste rock surfaces at the Bingham Canyon Mine, Utah.

Voluntary recolonization of sulfide-bearing waste rock dumps by native vegetation is inhibited by the harsh chemical and physical conditions. The success of volunteer vegetation on the waste rock surfaces at the Bingham Canyon (Utah) porphyry copper deposit is most strongly dependent on the soil pH and salinity, and to a lesser extent on physical characteristics such as compaction and distance from seed source. Vegetation cover and richness both decline below a paste pH of about 6 and above a paste conductivity of about 0.7 dS/m (for a 1:1 soil to water mixture). No significant vegetation establishment occurs below a soil pH of about 4.5. Young sulfide-bearing waste rock surfaces at Bingham Canyon have high salinity, but as reactive pyrite is depleted and salts are flushed from the soil, the salinity eventually declines, allowing volunteer native vegetation to become established on surfaces with a circumneutral pH. Under natural conditions, the pH of older acidic weathered surfaces will recover very slowly, but it can be rapidly raised by adding relatively small amounts of limestone because there are few intact reactive sulfides. For uncompacted waste rock surfaces with favorable chemical conditions, less than 90% gravel content, and that are located near a native seed source, the arithmetic mean volunteer vegetation cover was 56 +/- 24% and the mean species richness was 17 +/- 5. These data indicate that with adequate surface preparation and limestone addition, direct planting of older, acidic, but low salinity waste rock surfaces can greatly accelerate natural revegetation.

Role of mitochondrial DNA tRNA leucine and glucagon receptor missense mutations in Utah white diabetic patients.

Recently, subtypes of typical NIDDM were suggested based on missense mutations of mitochondrial DNA [tRNALeu(UUR)] and the glucagon receptor gene (Gly40Ser). Together these mutations might explain NIDDM in 5--8% of patients. To test the hypothesis that these mutations play an important role in a Northern European population with a strong family history of diabetes, we screened members of 45 families selected for having two or more diabetic siblings and 62 additional unrelated diabetic individuals for both mutations. We also examined 74 nondiabetic control subjects. Mitochondrial DNA mutations were not detected despite our ability to detect as little as 3% heteroplasmy in a sample from an individual known to carry the mutation. Likewise, the glucagon receptor Gly40Ser mutation was present in a single diabetic patient who on subsequent investigation was of Italian descent. Thus, neither subtype of NIDDM is present in the Utah diabetic population, which is reflective of other Northern European populations.

Field-caught Culex erythrothorax larvae found naturally infected with West Nile virus in Grand County, Utah.

Culex erythrothorax larvae were collected from a bulrush-cattail marsh near Moab, Grand County, Utah, October 28, 2004, and found positive for West Nile virus (WNV) RNA by real-time reverse-transcriptase polymerase chain reaction (RT-PCR). This demonstrates WNV vertical transmission in this species in the wild and suggests that vertical transmission in overwintering Cx. erythrothorax larvae may contribute to WNV overwintering.

Hydatid disease screening: Sanpete County, Utah, 1971-1976.

Between 1971 and 1976 approximately 20% (2,265) of the population of Sanpete County, Utah, was screened for hydatid disease (Echinococcus granulosus) by intradermal, indirect hemagglutination, and bentonite flocculation tests. Of 34 persons who had follow-up chest radiographs and radioisotope liver scans, 6 were found to have asymptomatic hepatic cysts. If a participant who had pulmonary cysts and negative screening tests were included, the prevalence of asymptomatic hydatid disease would be 3 per 1,000. During the same period, 82 (148 per 1,000) of 553 dogs successfully purged and examined had E. granulosus infections. Human cyst carriage was associated with dog ownership, particularly of infected dogs or in conjunction with sheep raising as the main livelihood. Combinations of immunodiagnostic tests were more efficacious in identifying cyst carriers than the tests used singly. Limitation of screening to high risk groups (e.g., sheep raisers with dogs) can reduce costs without reducing yield. Optimum management of the cyst carrier awaits further information on the natural history of asymptomatic hydatid disease.

A serologic survey of mule deer and elk in Utah.

Sera from mule deer (Odocoileus hemionus) and elk (Cervus canadensis) in central and northern Utah were tested for the prevalence of antibodies to 11 diseases communicable to man or domestic livestock. Antibodies to Francisella tularensis (at 1:20) were found in 47 of 88 (53.4%) elk and 1 of 89 (1.1%) deer. A screening slide agglutination test for titers to Brucella (at 1:20) showed two reactors in elk but none in deer sera. No positive antibody titers were obtained in tests for anaplasmosis, Colorado tick fever, Rocky Mountain spotted fever, Q-fever, psittacosis, Powassan, western equine encephalitis, St. Louis encephalitis and California encephalitis.

Trichomoniasis as a factor in mourning dove population decline in Fillmore, Utah.

We examined whether trichomoniasis had been a factor in a dramatic mourning dove (Zenaida macroura) population decline in Fillmore, Utah (USA). We reasoned that if we could not find a high proportion of doves showing clinical signs of disease then the population was not being affected. Prevalences of Trichomonas gallinae in doves were 21% for 1992 and 14% for 1993. We also examined 230 birds and found only one with oral lesions. These prevalences were similar to those observed at the same study site in the 1950's, or reported elsewhere. Based on our results, we believe that trichomoniasis was not affecting the Fillmore mourning dove population at the time of our study.

Infectious keratoconjunctivitis in free-ranging mule deer (Odocoileus hemionus) from Zion National Park, Utah.

An epizootic of infectious keratoconjunctivitis (IK) was studied opportunistically in free-ranging mule deer (Odocoileus hemionus) from Zion National Park, Utah (USA), from November 1992 to March 1994. Moraxella sp. and Chlamydia sp. were isolated from the conjunctiva of two of seven deer. In addition, Thelazia californiensis occurred on the conjunctivas of six of seven deer. Based on field observations, adults appeared to be affected clinically at a higher incidence during both years as opposed to juveniles. Corneal opacity was the most apparent clinical sign from 1992 to 1993. However, in the following year, blepharospasm and epiphora were noted more often. We were also able to document the clinical recovery of three affected deer. In addition, Moraxella sp. was recovered from the eyes of a clinically unaffected deer 1 year after the epizootic occurred.

Serologic survey for diseases in free-ranging coyotes (Canis latrans) from two ecologically distinct areas of Utah.

The influence of habitat and associated prey assemblages on the prevalence of canine diseases in coyotes (Canis latrans) has received scant attention. From December 1997 through December 1999, we captured 67 coyotes in two ecologically distinct areas of Utah (USA): Deseret Land and Livestock Ranch and US Army Dugway Proving Ground. These areas differ in habitat and prey base. We collected blood samples and tested for evidence of various canine diseases. Prevalence of antibodies against canine parvovirus (CPV) was 100% in the Deseret population and 93% in the Dugway population. All juveniles in both populations had been exposed. We found no difference in the prevalence of antibodies against canine distemper virus (CDV) between the two populations (7% versus 12%; P = 0.50). However, we did find an increase in antibodies with age in the Deseret population (P = 0.03). Evidence of exposure to canine adenovirus (CAV) was found in both populations (52% and 72%; P = 0.08). Prevalence of CAV antibodies was influenced by age on both areas (Deseret: P = 0.003; Dugway: P = 0.004). Antibodies to Francisella tularensis were low on both areas (2% and 4%). We found a significant difference (P = 0.001) in the prevalence of exposure to Yersinia pestis between the two populations: 73% in Deseret compared to 11% in Dugway. This difference is most likely due to the prey species available in the two ecologically distinct study areas.

Pulse oximetry sensor recycling cuts Utah hospital's costs.

A Utah hospital has cut some of its costs with a reprocessing program for disposable pulse oximetry probes. The hospital expects to save up to $120,000 annually. Some hospitals may already reuse disposable devices, but they could better manage reuse by developing written policies and procedures, the hospital says.

Turnover at the top: Utah hospital CEOs in a turbulent era.

This retrospective study describes the rate and causes of CEO turnover between 1973 and 1987 in Utah community and noncommunity hospitals. Both voluntary (i.e., self-initiated) and involuntary (i.e., organization-initiated) turnover were examined. For the overall period, the annual average turnover rate was 16.6 percent; the major component was the category "taking another hospital administration position or promoted within a multihospital system." In recent years, the turnover rate has been increasing, and the category of those being forced out has been comprising an increasing percentage of the turnover. For the 15-year period, the lowest rate of turnover and turnover due to force out were in the largest hospitals--all of which are urban, all but one of which belongs to a multihospital system, and none of which is for profit. Future research should incorporate retrospective and prospective studies to better understand, predict, and control hospital CEO turnover.

Linkage of a composite inhibitory phenotype to a chromosome 22q locus in eight Utah families.

Eight Utah multigenerational families, each with three to six cases of schizophrenia, were phenotyped with two specific measures of inhibitory neurophysiological functioning, P50 auditory sensory gating (P50), and antisaccade ocular motor performance (AS). A genomewide linkage analysis was performed to screen for loci underlying a qualitative phenotype combining the P50 and AS measures. For this composite inhibitory phenotype, the strongest evidence for linkage was to the D22s315 marker on chromosome 22q (lod score = 3.55, theta = 0) under an autosomal dominant model. Simulation analyses indicate that this 3.55 lod score is unlikely to represent a false positive result. Lod scores were 2.0 or greater for markers flanking D22s315. A nonparametric linkage (NPL) analysis of the chromosome 22 data showed evidence for allele sharing over the broad region surrounding D22s315 with a maximum NPL score of 3.83 (p = .002) for all pedigrees combined.

Costs of medical injuries in Utah and Colorado.

Patient injuries are thought to have a substantial financial impact on the health care system, but recent studies have been limited to estimating the costs of adverse drug events in teaching hospitals. This analysis estimated the costs of all types of patient injuries from a representative sample of hospitals in Utah and Colorado. We detected 459 adverse events (of which 265 were preventable) by reviewing the medical records of 14,732 randomly selected 1992 discharges from 28 hospitals. The total costs (all results are discounted 1996 dollars) were $661,889,000 for adverse events, and $308,382,000 for preventable adverse events. Health care costs totaled $348,081,000 for all adverse events and $159,245,000 for the preventable adverse events. Fifty-seven percent of the adverse event health care costs, and 46% of the preventable adverse event costs were attributed to outpatient medical care. Surgical complications, adverse drug events, and delayed or incorrect diagnoses and therapies were the most expensive types of adverse events. The costs of adverse events were similar to the national costs of caring for people with HIV/AIDS, and totaled 4.8% of per capita health care expenditures in these states.

Attitudes toward the genetic testing of children among adults in a Utah-based kindred tested for a BRCA1 mutation.

Advances in molecular biology and genetics have led to the identification of the breast/ovarian cancer susceptibility genes BRCA1 and BRCA2, along with tests to detect mutations in these genes. Although the appropriateness of BRCA1/2 genetic testing for children has been debated in the literature, little is known about the attitudes of individuals who have undergone cancer susceptibility testing. The present study focused on attitudes toward BRCA1 testing for children among 218 adults from a Utah-based kindred who had received BRCA1 test results. Results indicated that approximately one-fourth of the participants would permit BRCA1 testing for children under the age of 18. General attitudes about genetic testing were predictive of attitudes toward the testing of children. In addition, men and individuals without a BRCA1 mutation were more likely to agree that minors should be allowed BRCA1 testing. Individuals whose mother had been affected with breast cancer were less likely to permit testing for minors. Among parents of minor children, less than one-fifth indicated that they would want BRCA1 testing for their own children; carrier status was not predictive of attitudes toward testing their own children. As breast/ovarian cancer susceptibility testing continues to be disseminated into clinical settings, there may be an increase in the number of test requests for minors. The findings of the present study represent an important step in exploring attitudes about genetic testing of children among individuals who have received cancer susceptibility test results.

When more means less. Utah gets federal approval limiting Medicaid services to some to provide a basic health package to 25,000 low-income uninsured.

Utah hospitals are cautiously optimistic about a controversial new Medicaid project that would expand health insurance coverage to 25,000 of the state's low-income workers but would not cover hospitalization. The project marks the first time the federal government has let a state offer a Medicaid benefit plan that fails to cover hospitalization and reduces benefits for some enrollees in order to expand access for others.

Houseboat-associated carbon monoxide poisonings on Lake Powell--Arizona and Utah, 2000.

During August 2000 at Lake Powell in the Glen Canyon National Recreation Area on the Arizona-Utah border, two brothers died of carbon monoxide (CO) poisoning as they swam near the stern of a houseboat while the onboard gasoline-powered generator was operating. As a result of these deaths, an investigation was initiated by the U.S. National Park Service (NPS) with assistance from the U.S. Department of the Interior, CDC's National Institute for Occupational Safety and Health, and the U.S. Coast Guard. In addition to investigating the deaths of the two brothers, the multiagency team evaluated visitor and worker boat-related CO exposures at Lake Powell. The study identified nine boat-related fatal CO poisonings since 1994 and approximately 100 nonfatal poisonings since 1990. This report describes the preliminary results of an ongoing investigation of watercraft-related CO poisonings on Lake Powell.

Rapid deployment of an electronic disease surveillance system in the state of Utah for the 2002 Olympic Winter Games.

The key to minimizing the effects of an intentionally caused disease outbreak is early detection of the attack and rapid identification of the affected individuals. The Bush administration's leadership in advocating for biosurveillance systems capable of monitoring for bioterrorism attacks suggests that we should move quickly to establish a nationwide early warning biosurveillance system as a defense against this threat. The spirit of collaboration and unity inspired by the events of 9-11 and the 2002 Olympic Winter Games in Salt Lake City provided the opportunity to demonstrate how a prototypic biosurveillance system could be rapidly deployed. In seven weeks we were able to implement an automated, real-time disease outbreak detection system in the State of Utah and monitored 80,684 acute care visits occurring during a 28-day period spanning the Olympics. No trends of immediate public health concern were identified.

Evidence for gene-environmental interactions in Utah families with hypertension, dyslipidaemia and early coronary heart disease.

1. Among 45,258 Utah families surveyed, about 4% have a strong aggregation of early coronary disease. In detailed clinical evaluation, about 21% of such high risk coronary families were found to have familial dyslipidaemic hypertension (FDH) and about 3% were found to have heterozygous familial hypercholesterolaemia (hFH). 2. Common and potentially modifiable environmental factors seem to play an important role in these high risk families. Non-genetic obesity promotes the expression of FDH. A high fat diet promotes the expression of FH. Cigarette smoking promotes earlier death in all coronary prone families. 3. Practical approaches are suggested for helping coronary prone pedigrees by applying our understanding of genetic and environmental factors that promote earlier coronary disease onset.
