Maternal mortality in Utah.

OBJECTIVE: To determine trends in maternal deaths in Utah, identify opportunities for preventive intervention, and analyze the mechanism of reporting maternal deaths. METHODS: A retrospective review was performed of maternal death certificates and medical records in Utah from January 1, 1982, through December 31, 1994. RESULTS: Sixty-two maternal deaths were identified. The risk of maternal death increased with maternal age and parity. The classic triad of hemorrhage (n = 8), infection (n = 5), and preeclampsia-eclampsia (n = 3) remains an important contributor (16 of 62 or 25.8%). However, trauma (n = 10), pulmonary embolism (n = 10), and maternal cardiac disease (n = 9) now account for 46.8% (29 of 62) of maternal deaths. A greater number of direct obstetric causes of maternal death (n = 20) were deemed preventable than indirect obstetric causes (n = 1) or nonobstetric causes (n = 4). CONCLUSION: Trauma, pulmonary embolism, and maternal cardiac disease have emerged as the most common identifiable causes of maternal death. Improvements in prevention, earlier diagnosis, and aggressive treatment of these conditions are necessary to achieve the Public Health Service year 2000 objective of a 50% reduction in maternal mortality ratios (using the 1987 ratio as a baseline).

Cyclizine abuse by teenagers in Utah.

Substance abuse by teenagers is common, often involving use of alcohol and illicit drugs. Ingestion of cyclizine hydrochloride, a nonprescription medication, was noted to occur frequently in Utah for abuse reasons. A retrospective review was conducted of patients younger than 18 years of age over a 3-year period who intentionally ingested cyclizine identified from Utah Poison Control Center records. Eighty patients were included; 42 patients underwent hospital record review. Abuse accounted for 89% of cyclizine ingestions; hallucinations (70%) and confusion/disorientation (40%) were the most notable symptoms. Tachycardia (52%) and systolic hypertension (69%) were frequently present in patients who presented to a hospital. No serious complications occurred. This study illustrates teenage abuse of one nonprescription antihistamine presumably to induce hallucinations. Abuse of over-the-counter medications by adolescents may be more appealing than illicit drug use for numerous reasons, and may be more common than appreciated.

Presurgical biopsychosocial variables predict medical and compensation costs of lumbar fusion in Utah workers' compensation patients.

BACKGROUND CONTEXT: Elective lumbar fusion surgery is a prevalent and costly procedure that requires a lengthy rehabilitation. It is important to identify presurgical biopsychosocial predictors of medical and compensation costs in such patients. PURPOSE: To determine if presurgical biopsychosocial variables are predictive of compensation and medical costs in a cohort of Utah lumbar fusion patients receiving workers' compensation. STUDY DESIGN/SETTING: A retrospective-cohort study consisting of a review of presurgical medical records and accrued medical and compensations costs. PATIENT SAMPLE: A consecutive sample of 203 compensated workers from Utah who underwent lumbar fusion from 1990 to 1995. Patients were at least 2 years postsurgery. OUTCOME MEASURES: Total accrued medical and compensations costs. METHODS: A retrospective review of presurgical biopsychosocial variables and total accrued medical and compensation costs was conducted. RESULTS: Presurgical variables from each of the biopsychosocial domains were statistically significantly correlated with medical and compensation costs. Social and biological variables were the best predictors of total compensation costs, whereas psychological variables were better predictors of total medical costs. CONCLUSIONS: Compensation and medical costs associated with posterolateral lumbar fusion can be predicted by preintervention biopsychosocial variables. Cost reduction programs might benefit from identifying biopsychosocial factors related to increased costs.

The pandemic of Salmonella enteritidis phage type 4 reaches Utah: a complex investigation confirms the need for continuing rigorous control measures.

In 1995, Salmonella Enteritidis (SE) cases in the state of Utah increased fivefold. Isolates were identified as phage type 4 (PT4). Risk factors and sources of infection were investigated in two case-control studies, a traceback of implicated foods, and environmental testing. Forty-three patients with sporadic infections and 86 controls were included in a case-control study of risk factors for infection. A follow-up case-control study of 25 case and 19 control restaurants patronized by case and control patients examined risks associated with restaurant practices. In the first case-control study, restaurant dining was associated with illness (P = 0.002). In the follow-up case-control study, case restaurants were likelier to use > 2000 eggs per week (P < 0.02), to pool eggs (P < 0.05), and to use eggs from cooperative 'A' (P < 0.009). Eggs implicated in separately investigated SE PT4 outbreaks were traced to cooperative 'A', and SE PT4 was cultured from one of the cooperative's five local farms. We conclude that SE PT4 transmitted by infected eggs from a single farm caused a fivefold increase in human infections in Utah.

The financial impact on community mental health centers of capitated contracts with Medicaid: the Utah Prepaid Mental Health Plan.

Under the Utah Prepaid Mental Health Plan, three of the eleven Community Mental Health Centers in Utah signed capitation contracts with the state Medicaid program. The capitated Centers initially accepted the risk for inpatient care, with the risk later being extended to also include outpatient services. This study contrasts the financial experiences of the capitated Centers and five noncontracting Centers. While various patterns of financial management are evident in the data, it appears that the decision to contract had, at worst, a neutral effect on overall financial performance. Managed care programs with different designs may have different results.

Segregation analysis of HDL cholesterol in the NHLBI Family Heart Study and in Utah pedigrees.

We investigated the genetic determination of high-density-lipoprotein cholesterol (HDL-C) levels in the NHLBI Family Heart Study by segregation analysis. Included was a total of 3755 subjects from 560 randomly selected nuclear families and 522 families selected due to a high family risk of coronary heart disease (CHD). In the whole dataset, there was no evidence for an allele at a major gene locus responsible for HDL-C levels lower than the population mean or even for significant bimodality for low levels of HDL-C. However, we observed evidence for a recessive allele that was associated with higher HDL-C levels than average. This evidence for a recessive major gene was independent of triglyceride concentrations and was most strongly observed in families recruited for CHD. The environmental model was rejected (P=0.0027) while the codominant and recessive models were not rejected (P=0.085 and P=0.133, respectively). The dominant model was also rejected (P<0.0001). In the recessive segregation model, the means of those inferred to be homozygous for the high HDL-C allele and those without the high HDL-C allele were separated by about 25 mg/dl HDL-C (73.9+/-1.99 vs 48.2+/-0.36 mg/dl). Because these results were unexpected, segregation was tested in a separate sample of 2013 individuals in 85 large pedigrees ascertained for early heart disease deaths, early stroke deaths, and early hypertension in Utah. Similar evidence for an allele at a major gene locus for high HDL-C was found. In summary, we did not find evidence for an allele at a major gene locus associated with low HDL-C levels segregating in pedigrees recruited for the NHLBI Family Heart Study, or in pedigrees ascertained in Utah for early CHD or related phenotypes. Instead we found some evidence for the segregation of an allele associated with high HDL-C. d

Comparison of a picture-sort food-frequency questionnaire with 24-hour dietary recalls in an elderly Utah population.

OBJECTIVE: To evaluate the 137-item Utah Picture-sort Food-frequency Questionnaire (FFQ) in the measurement of usual dietary intake in older adults. DESIGN: The picture-sort FFQ was administered at baseline and again one year later. Three seasonal 24-hour dietary recall interviews were collected during the year between the two FFQs. Mean nutrient intakes were compared between methods and between administrations of the FFQ. SETTING: The FFQ interviews were administered in respondents' homes or care-centres. The 24-hour diet recalls were conducted by telephone interview on random days of the week. SUBJECTS: Two-hundred-and-eight men and women aged 55-84 years were recruited by random sample of controls from a case-control study of nutrition and bone health in Utah. RESULTS: After adjustment for total energy intake, median Spearman rank correlation coefficients between the two picture-sort FFQs were 0.69 for men aged < or = 69 years, 0.66 for men aged > 69 years; and 0.68 for women aged < or = 69 years, 0.67 for women aged > 69 years. Median correlation coefficients between methods were 0.50 for men < or = 69 years old, 0.52 for men > 69 years old; 0.55 for women < or = 69 years old, 0.46 for women > 69 years old. CONCLUSIONS: We report intake correlations between methods and administrations comparable to those reported in the literature for traditional paper-and-pencil FFQs and one other picture-sort method of FFQ. This dietary assessment method may improve ease and accuracy of response in this and other populations with low literacy levels, poor memory skill, impaired hearing, or poor vision.

Air pollution and fatal lung disease in three Utah counties.

A unique situation found in two Utah counties has made it possible to estimate the fraction of respiratory cancer and nonmalignant respiratory disease (NMRD) deaths, which are attributable to community air pollution (CAP) in one county. The two counties were very similar in many ways, including low smoking rates, until a steel mill constructed during WW II caused substantial CAP in one of them. Subsequent differences in mortality rates from both respiratory cancer and NMRD are striking. A third county, similar to many counties outside Utah, was included in the analysis for comparison. In one county, 30-40% of the respiratory cancer and NMRD deaths were attributable to CAP. In this county, NMRD deaths (but not respiratory cancer deaths) were slightly more frequent than in Salt Lake County where smoking rates were twice as high.

A report of two smokeless tobacco surveys and associated intervention strategies among Utah adolescents.

Smokeless tobacco is an increasingly popular substance, especially among male adolescents. We determined the prevalence of smokeless tobacco use and evaluated selected factors associated with it among 8,902 students in grades 7 through 12 in the Davis County, Utah, School District. The students responded anonymously in their classrooms to a 16-item self-reporting questionnaire. Results indicated that smokeless tobacco usage was predominately a male phenomenon in all grades and schools, as illustrated by prevalence rates "within the past week" for junior high school students (male: 15.0%; female: 1.1%). Modal responses regarding users' source of supply revealed "friends" as the leading source for junior high students (43.1%) and direct purchase for senior high students (62.2%). Peer usage or nonusage of smokeless tobacco was found to be directly and proportionately correlated with smokeless tobacco users' participation in the school activity designated "sports" for both junior high (39%) and senior high school students (36.2%). Subsequently, clinical evaluation of high school male athletes was undertaken. To our surprise, the rate of lesion detection among members of this group, previously judged to be the subjects most likely to use smokeless tobacco, fell far short of the anticipated rate. We believe the reason for the low rate may be the result of numerous efforts to educate students and coaches, the reinforcement of existing tobacco use policies by the Davis County School District, and the reiteration to smokeless tobacco vendors of the terms of the Utah laws relative to smokeless tobacco sales. This health-endangering behavior deserves a concerted educational thrust by health professional, parents, and teachers, with emphasis on prevention.

Metals mimic airway epithelial injury induced by in vitro exposure to Utah Valley ambient particulate matter extracts.

Epidemiologic studies have shown positive associations between changes in ambient particulate matter (PM) levels in Utah Valley during 1986-1988, and the respiratory health of the local population. Ambient PM reductions coincided with closure of an open-hearth steel mill, the major industrial source of particulate emissions in the valley. In this report, water extracts of PM filters from steel mill operational (UE-86, UE-88) and closure (UE-87) periods were analyzed for their elemental composition. Their relative toxicity was determined by exposing primary rodent airway epithelial cultures to equal masses of extracted material. To elucidate extract subcomponents mediating the effects observed, cells were also exposed to surrogate metal mixtures. Potential interactions between the two predominant metals in the UE-86/88 samples, zinc (Zn) and copper (Cu), were further investigated. Data indicated that, relative to the UE-87 (plant closed) sample, UE-86/88 samples contained more sulfate, calcium, potassium,magnesium and, although present in much lower amounts, a variety of metals including Zn,Cu, iron, lead, strontium, nickel, manganese, and vanadium (V). Cell exposure to UE-86 and UE-88, but not UE-87, resulted in time- and concentration-dependent epithelial injury based on biochemical and light/electron microscopic changes. Cell injury induced by metal mixtures containing equivalent amounts of Zn + Cu + V was commensurate with that induced by the corresponding extract, although divergent antioxidant responses were observed. Exposure to Zn + Cu resulted in significantly greater epithelial toxicity and stress (c-Jun N-terminal protein kinase activation) responses than did exposure to Zn or Cu individually. The parallel epithelial injury induced by the extracts and their surrogate Zn + Cu + V mixtures suggests that these metals are mediating the acute airway epithelial effects observed; however, metal interactions appear to play a critical role in the overall cellular effects induced by the PM-derived extracts. These experimental findings are in good accord with epidemiologic reports of adverse airway and respiratory health health effects in Utah Valley residents.

Suicide rates and religious commitment in young adult males in Utah.

Previous studies have used population data to demonstrate an inverse association between suicide rates and religious commitment. This report examines Utah suicide rates for young men aged 15-34 years, stratified by their membership in and commitment to the Church of Jesus Christ of Latter-day Saints (LDS), the predominant religion in Utah. All state death records for males from 1991 to 1995 were obtained and linked to LDS church deceased membership records to obtain a measure of religious commitment that is not self-reported. Religious commitment for LDS church members was determined by age-appropriate priesthood office. Of the 27,738 male deaths reported, 15,555 (56%) linked to an LDS church record using a probabilistic linking program. Using active (high religious commitment) LDS as the reference group, the less-active (low religious commitment) LDS group had relative risks of suicide ranging from 3.28 (ages 15-19 years) to 7.64 (ages 25-29 years); nonmembers of the LDS church had relative risks ranging from 3.43 (ages 15-19 years) to 6.27 (ages 20-24 years). Although the mechanism of the association is unclear, higher levels of religiosity appear to be inversely associated with suicide.

Genetic basis of familial dyslipidemia and hypertension: 15-year results from Utah.

The genetic and environmental determinants of hypertension, lipid abnormalities, and coronary artery disease (CAD) have been studied for 15 years in Utah in population-based multigenerational pedigrees (2500 subjects among 98 pedigrees), twin pairs (74 monozygous and 78 dizygous), hypertensive siblings (131 sibships), siblings with CAD before age 55 (45 sibships), and anecdotally ascertained pedigrees with type II diabetes (271 subjects among 16 pedigrees), lipoprotein lipase deficiency (106 subjects in a single pedigree), and familial hypercholesterolemia (502 heterozygotes among 50 pedigrees). Estimates of heritability ranged from 20 to 75% for blood pressures and blood lipids. A strong positive family history predicts a future occurrence of hypertension (relative risk [RR] = 3.8) and CAD (RR = 12.7). Segregating single-gene effects were found for several 'intermediate phenotypes' associated with hypertension (erythrocyte sodium-lithium countertransport, intraerythrocytic sodium, a relative fat pattern, total urinary kallikrein excretion, and fasting insulin levels). Strong single-gene effects in segregation analysis were also found for low-density lipoprotein (LDL) cholesterol, lipoprotein (a) (Lp[a]), low high-density lipoprotein (HDL) cholesterol, and high apolipoprotein (apo) B. Deoxyribonucleic acid (DNA) markers of lipid abnormalities or hypertension have included LDL-receptor defects, lipoprotein lipase deficiency, high Lp(a), familial defective apo B, decreased quantitative levels of apo B, apo E phenotype, angiotensinogen, and 'glucocorticoid remediable aldosteronism (GRA) hypertension.' Also tested in Utah studies, but not found to be DNA markers for hypertension, were the genetic loci for the structural genes for renin and angiotensin-converting enzyme, and the sodium antiport system. In addition, important gene-gene interactions (LDL receptor with apo E2) and gene-environment interactions (kallikrein with potassium intake) were found.(ABSTRACT TRUNCATED AT 250 WORDS)

Prostate cancer susceptibility locus HPC1 in Utah high-risk pedigrees.

A prostate cancer susceptibility locus ( HPC1 ) at 1q24-25 has been identified. Subsequent analysis showed that the majority of the evidence for localization was provided by families with relatively young (<65 years) average age at diagnosis. We examined evidence for linkage to this region in a set of 41 extended multi-case prostate cancer pedigrees containing 440 prostate cancer cases. Genotyping of five short tandem repeat markers in the region was performed on DNA from 1724 individuals, including 284 prostate cancer cases. In comparison with the families reported in the initial localization, the Utah pedigrees are generally much larger (average of 10.7 versus 5.1 cases) and have an older average age at diagnosis (69 versus 65 years). Two- and three-point linkage analyses were conducted using a previously reported model and provided replication for HPC1 (two-point: LOD = 1.73, P = 0.005 at D1S196; three-point: LOD = 2.06, P = 0.002 for the interval D1S196-D1S416 ). The youngest quartile (by median age at diagnosis) yielded a maximum LOD of 2.82, P = 0. 0003 (at D1S215-D1S222 ), compared with a maximum LOD of 0.73, P = 0. 07 for the oldest quartile pedigrees at the same locus. Further analysis with an age-dependent model, specifying higher sporadic rates for older cases, suggests that the linkage evidence may be lower than expected given the power of the resource due to a high sporadic rate in the large Utah pedigrees.

The acceptability of posthumous human ovarian tissue donation in Utah.

BACKGROUND: Infertility due to accelerated loss of ovarian follicles/oocytes may occur through numerous mechanisms. As a result, posthumous human oocyte donation, banking and maturation protocols for research and fertility restoration are current interests in reproductive medicine. METHODS: A computer-generated sample of Utah residents (n = 704) were surveyed regarding demographics, willingness to donate organs, IVF acceptability and posthumous follicle/oocyte donation for: research, fertilization with monitoring to the preembryo stage (eight cells), and fertilization and subsequent transfer of embryos derived from themselves, their partner or non-spousal relative for whom they act as guardian. RESULTS: Ovarian tissue donation for follicle/oocyte retrieval, maturation and scientific investigation without fertilization was acceptable (>or=70%) to a majority of the Utah population. However, fertilization of oocytes or fertilization and transfer of resulting preembyos derived from such donations to cause a pregnancy was less acceptable (58.3% and 57.4%, respectively) in the population responding for their own or partner's oocytes, and more so when the donation was guardian-directed (54.8% and 52.1%, respectively). Similar declines in the level of acceptance were noted when those who had an express interest in such donations (ovarian failure or surgical castration) were surveyed (n = 50). CONCLUSIONS: This study substantiates the ethical recommendation that explicit prior written consent of the donor be obtained when ovarian tissue donations are procured for fertilization, or transfer of a preembryo to cause a pregnancy. In light of the rapid technological advancements in ovarian follicle/oocyte cryopreservation and maturation, the time may have come to provide potential organ donors the opportunity to specify their desires regarding ovarian tissues when registering for organ donation.

Cancer in Utah Mormon women by church activity level.

In light of low cancer rates by the Mormon Church, this study classifies female Mormon cancer patients in Utah according to measures of adherence to Church doctrines. The distribution by Church activity level is compared for each site to a group of other cancer sites felt to represent the overall activity level distribution of Utah Mormon women. Mormon women classified as having the strongest adherence to Church doctrines had lung cancer rates during 1966-1970 much lower than did women with the weakest adherence. The relationship was not as strong, however, as that seen in Mormon men when classified by lay priesthood office. Cancer of the uterine cervix also showed lower rates in the more active groups, but this finding was not statistically significant. Cancers of the breast and ovary did not show consistent associations with Church activity level, nor did most of the gastrointestinal cancers. These data suggest that some of the differences in cancer incidence between Mormons and non-Mormons may not be explained by adherence to specific Church doctrines.

Possible factors influencing distribution and prevalence of Echinococcus granulosus in Utah.

A descriptive epidemiologic study was designed to test an impression that infections of Echinococcus granulosus in dogs, sheep, and human beings were concentrated in central Utah, and to determine when and how the parasite was introduced into the state, which factors were involved in the distribution of the cestode, and which factors increased either a person's risk of infection of the number of people at risk. Data were secured by review of available records, interviews, questionnaires, and field observations. It was found that 37 of 39 infections in human beings, and seven of eight counties with endemic hydatid disease in dogs and sheep, are located in central Utah. Possible factors responsible for the increasing number of people at risk were use of local people as herders, the existence of community herds, and specific dog management practices. Determinants such as trailing sheep between seasonal pastures, association of sheepmen from several counties on winter range, and sheep marketing practices undoubtedly influence distribution of infections in dogs and sheep.

The Utah Leukemia Case-Control Study: dosimetry methodology and results.

This paper discusses the dosimetry methodology used to estimate bone marrow dose and the results of dosimetry calculations for 6,507 subjects in an epidemiologic case-control study of leukemia among Utah residents. The estimated doses were used to determine if a higher incidence of leukemia among residents of Utah could have been attributed to exposure to radioactive fallout from above-ground nuclear weapons tests conducted at the Nevada Test Site. The objective of the dosimetry methodology was to estimate absorbed dose to active marrow specific to each case and each control subject. Data on the residence of each subject were available from records of the Church of Jesus Christ of Latter-day Saints. Deposition of fallout was determined from databases developed using historical measurements and exposure for each subject from each test was estimated using those data. Exposure was converted to dose by applying an age-dependent dose conversion factor and a factor for shielding. The median dose for all case and control subjects was 3.2 mGy. The maximum estimated mean dose for any case or control was 29 +/- 5.6 mGy (a resident of Washington County, UT). Uncertainties were estimated for each estimated dose. The results of the dosimetry calculations were applied in an epidemiological analysis.

Distinctive emergency department usage for injury for workers' compensation cases in Utah in 1996.

To compare emergency department services paid by worker's compensation (WC) with services paid by other payers, a state database of 72,747 emergency department visits for injured adults (ages 21 to 54) in 1996 in Utah was analyzed. WC visits accounted for 21.6% (15,704) of all adult injury visits. The mean emergency department charge for WC visits was $282, and the admission rate was 17 per 1000 visits. The mean charge for other payers was $334, and the admission rate was 43 per 1000 visits. Differences were also found between these groups for Injury Severity Scores and diagnoses. In summary, WC emergency department usage was associated with less severe injuries than was emergency department usage for other payers in Utah in 1996.
