Early childhood vaccination in two rural counties--Nebraska, 1991-1992.

The national vaccination objectives for the year 2000 include increasing coverage for the recommended primary vaccination series* among children aged less than 2 years to at least 90% and to vaccinate at least 95% of school-aged children (1). Although baseline data for these two goals have been obtained in numerous urban settings (2), similar baseline data from rural populations are limited. To determine the vaccination status of children in rural Nebraska, where 51% (812,000) of Nebraska's residents live, the Nebraska Department of Health, in collaboration with Hastings College, conducted a retrospective study of school-aged children in grades kindergarten through six in two rural counties during the 1991-92 school year. This report summarizes the study findings.

A historical perspective on the University of Nebraska Medical Center's College of Dentistry Class of 1961.

We conducted a retrospective analysis of the University of Nebraska Medical Center (UNMC) College of Dentistry (COD) Class of 1961 to glean information that might be useful in the design of dental education programs in Nebraska and elsewhere. We scanned annual class newsletters, demographic statistics for students entering the UNMC dental program for each decade from 1961 to 2001, and UNMC COD alumni data for patterns and themes among thirty-two dental professionals. Eighty-four percent of those contacted provided responses to a survey. We found that, like current dental cohorts nationwide, the UNMC COD Class of 1961 is mostly of European ancestry (non-Hispanic) and male. But in contrast to current dental college graduates, the UNMC Class of '61 were able to rely upon self-employment and spousal and/or military support (GI Bill) to cover the costs of their dental education. They also were more likely to enter dental school before completion of an undergraduate degree and have a substantial work history before entering the UNMC dental program. Although the most common reason for attending dental school related to independence and financial security, "time with family" and "family vacations" were the next most important reasons cited for becoming dental professionals. Among '61 graduates, the average number of years spent in the dental profession is thirty-seven years. Despite the notable changes in dental technology and the continual need for updating knowledge and skill, eight members of the UNMC COD Class of 1961 continue to practice dentistry. Most maintain contact with other class members, providing support to former classmates and maintaining an identity with their alma mater, the University of Nebraska.

A rural-urban comparison of prehospital emergency medical services in Nebraska.

BACKGROUND: Provision of emergency medical services (EMS) in the rural United States presents a unique challenge. While rural and urban EMS outcomes have been compared, differing urban-rural population characteristics and roles for rural ambulance teams can confound such comparisons. METHODS: A year-long study of the prehospital EMS was conducted in rural Richardson County, Nebraska. Data were collected on the age, sex, and race of patients, response time, transport distance, medical problems encountered, and treatment rendered enroute. These data compared with those from an urban Lancaster County comparison group and statistical data from the Nebraska State Health Department. RESULTS: In the rural county, 70 percent of calls involved the elderly, whereas 38 percent of the urban calls and 36 percent of the Nebraska State calls involved the elderly. The rural ambulance service was more likely to provide for routine transfers, to involve patients with fractures and cardiorespiratory and neurologic problems, and twice as likely to result in hospital admission than was the urban ambulance service. The frequency with which advanced life support measures were applied in the rural area was similar to that in the urban area. The rural area response times were equivalent to the urban area response times after the rural area long-distance transfers were excluded. The location of service in the rural area was more likely to be the hospital or nursing home, whereas the urban location was more likely to be a home, on a highway, or in a public setting. CONCLUSIONS: Prehospital EMS in this rural location involved a predominantly elderly population with a large number of routine transfers linking the nursing home and community hospital. Further comparisons of rural and urban EMS outcomes should account for possible differences in type and severity of illness and type and location of service.

Dietary fluoride supplements for Nebraska's children--the role of the physician.

1. All children should receive one form of systemic fluoride and appropriate forms of topical fluoride. 2. If a child is not receiving optimally fluoridated water, the physician or dentist should prescribe dietary fluoride supplements (tablets or drops). 3. The correct dosage must be determined based on patient age and fluoride content of the patient's main water source(s). 4. Special attention is necessary concerning fluoride intake for children breast-feeding or consuming infant formula. 5. To arrive at the correct fluoride dose, these steps should be followed: A. Always have a sample of the main drinking water source (usually home water) analyzed for the fluoride content before prescribing a fluoride supplement, if you do not have other specific knowledge of water fluoride content. The Laboratory Division of the Nebraska State Department of Health provides water fluoride assay services. B. When the fluoride content of the water has been determined, the fluoride level and the child's age should be matched on Table 1 to arrive at the correct supplement dose. 6. The Division of Dental Health of the Nebraska State Department of Health can provide lists of communities and schools in Nebraska that are optimally fluoridated.

Trends in teenage pregnancy. A comparison of Douglas County, Nebraska, and national statistics.

Teenage pregnancy is a significant health and economic problem in the United States. However, both national and Nebraska statistics show that teenage fertility rates and the percentage of teen births vs. total births are decreasing. The national rate decreased from 19% in 1975 to 13.7% in 1984. The Nebraska rate paralleled the national rate, decreasing from 13% in 1977 to 9.7% in 1984. The Douglas County, Nebraska, rate also decreased, from 21.8% in 1978 to 17.5% in 1985. These trends have been noted for both black and white teens and are statistically significant. The percentage of abortions and births to unmarried teens vs. nonteens has also decreased both nationally and statewide.

The Nebraska Veterinary Medical Association antidote depot.

The Nebraska Veterinary Medical Association provided financial assistance to establish an antidote depot system statewide at the 3 University of Nebraska veterinary diagnostic laboratories located in Lincoln, North Platte, and Mitchell. The depot system currently stocks atropine sulfate, methylene blue, activated charcoal, dimercaprol, and EDTA. Antidotes are available to all Nebraska veterinarians. Depot withdrawals are used for emergency treatment only and not for a convenient source of supply to replenish individual inventory. The depot system was designed to assist veterinary practitioners in treating toxicoses during catastrophic occurrences in which available inventories have been exhausted. Since time is of essence in most toxicoses, withdrawals from depot sites normally are made by veterinarians or their authorized representatives. There are no fees for using the depot system, but patrons are required to replace drugs at the specific storage site on an item-for-item basis, in like amount, and at current unit cost. Items are issued and replaced only as intact units.

Current tobacco use policies in Nebraska public schools.

A critical effort to reduce the harmful effects of tobacco is to promote tobacco abstinence among the nation's adolescent population. In this regard, the message of tobacco tolerance within the education system of the State of Nebraska was examined. Although the majority of schools surveyed have an encouraging policy regarding student smoking, it has not yet been universally implemented. In addition, the tobacco-use policies for non-students within public school buildings is concerning. The Nebraska Indoor Clean Air Act and the recent Environmental Protection Agency warning on second-hand smoke provides a framework for change. Health care providers can be proactive in encouraging their school districts to promote the goal of a Tobacco-Free Nebraska.

Nebraska outpatient care quality assessment.

Nebraska Hospital Market Areas (HMAs) with significantly and consistently high admission rates for Ambulatory Care Sensitive Conditions (ACSC) were identified using the Blue Cross and Blue Shield of Nebraska (BCBSN) small area analysis data. Two-thirds of those hospitalized were surveyed by Wiese Research of Omaha, Nebraska to determine if the cause for the high admission rates was related to outpatient care quality. BCBSN members living in HMAs without high admission rates were also surveyed for comparison purposes. The survey revealed that satisfaction with outpatient care was high, and that access (geographic or financial) was not a problem for either the test or control group. The test group did delay (for a short time) obtaining outpatient care when compared to the control group. Most of the control group stated that they obtained outpatient care the day symptoms started. Although the majority of the test group obtained outpatient care within a week, they were not as prompt in obtaining outpatient care as the control group. The types of conditions studied (ACSCS) are conditions that can rapidly become severe, therefore prompt treatment is imperative. The main reason given for chronic delays of both groups were that the condition "suddenly became serious." There may be implications for providers to use more "compliance-gaining" strategies in problem area, and for insurers to offer contract endorsements which would encourage members to obtain prompt treatment and preventive healthcare.

Cerebral ventricular size and neuropsychological impairment in young chronic schizophrenics. Measurement by the standardized Luria-Nebraska Neuropsychological Battery.

The relationship between size of cerebral ventricles in chronic schizophrenics and performance on a comprehensive neuropsychological battery, the Standardized Luria-Nebraska Neuropsychological Battery, was investigated. Ventricular size was determined by using a planimeter to measure the size of the lateral ventricles and the ventricular body, if present, on the computerized tomographic (CT) scan image that showed the largest lateral ventricles. This number was divided by the size of the brain as a whole on the same image of the CT scan to yield a ventricular brain ratio. This ratio was then correlated with the scores on the Luria-Nebraska Neuropsychological Battery. Eight of the 14 scales of the Luria-Nebraska Neuropsychological Battery correlated significantly at the .05 level with the ventricular brain ratio in a sample of 42 chronic schizophrenics with an average age of 32.3 years. Overall, there was a multiple correlation of .72 between the ventricular brain ratio and Luria scores. The overall ventricular brain ratio for the schizophrenics was significantly above that found in normal populations. Changes in the size of the ventricles in schizophrenics appear to have significant correlates with measures of neuropsychological performance.

Bovine trichomoniasis: Results of a slaughter survey in Colorado and Nebraska.

A total of 2,909 bulls was cultured for the presence of Trichomonas fetus at slaughter at 4 abattoirs in Colorado and Nebraska. Samples were collected using the dry pipette preputial scraping technique and were transported to diagnostic laboratories within 24 h. Of the bulls cultured, 5 were positive. The state of the last origin for each animal was Kansas, 1 bull, Montana, 1 bull, Nebraska, 1 bull, and Utah, 2 bulls. These results indicate and incidence of less than 1% (0.172%) of trichomoniasis in the populations tested, even in the states of Colorado and Nebraska where the larger numbers of bulls were cultured.

Relationships between language skills as assessed by the Halstead-Reitan battery and the Luria-Nebraska language-related factor scales in a nonaphasic patient population.

The study involved a comparison between language tests derived from the Halstead-Reitan and Luria-Nebraska neuropsychological test batteries. Language-related measures from each battery were entered into a factor analysis based on a sample of 150 nonaphasic neuropsychiatric patients. Five factors were extracted and were named Academic Achievement, Basic Skills, Verbal Intelligence, Auditory Discrimination, and Comprehension of Syntactical Relations. Measures from both the Halstead-Reitan and Luria-Nebraska loaded on most of these factors. A canonical correlation analysis revealed a strong relationship between the Halstead-Reitan and Luria-Nebraska measures. However, it was noted that interpretation of this relationship must be qualified by the association found between the measures used and educational achievement.

Detection of brain-damage in schizophrenics as measured by the Whitaker Index of Schizophrenic Thinking and the Luria-Nebraska Neuropsychological Battery.

Neuropsychological performance of schizophrenics with and without brain-damage was measured by the Whitaker Index of Schizophrenic Thinking and the Luria-Nebraska Neuropsychological Battery. Inpatient volunteers (11 brain-damaged and 15 non-brain-damaged) with a diagnosis of schizophrenia were administered both tests individually. Results indicated that 8 of the 14 summary scales of the Luria-Nebraska but none of the 5 scores on the Whitaker differentiated between groups. While cognitive variables as measured by the Whitaker may be further impaired with organicity, other variables measured by the Luria-Nebraska were more effective in differentiating between groups.

The Luria-Nebraska Neuropsychological Battery-Children's Revision: comparison of learning disabled and normal children matched on full scale IQ.

17 academically normal and 17 reading disabled children were matched on Full Scale IQ and compared on the Luria-Nebraska Neuropsychological Battery-Children's Revision. The academically normal group performed significantly better on the Expressive Language, Writing, Reading, and Rhythm subscales, which suggests that the Luria-Nebraska may be sensitive to deficits not reflected in Full Scale IQ. Results are consistent with previous research and support the validity of the Luria-Nebraska, although simplistic interpretation of the battery's subscales should be avoided.

Differentiation of chronic schizophrenics with and without ventricular enlargement by the Luria-Nebraska Neuropsychological Battery.

The present study investigated whether the Luria-Nebraska Neuropsychological Battery could be used clinically to differentiate schizophrenics with ventricular or sulcal enlargement from schizophrenics with no such enlargement as identified by a CT scan. The study investigated 42 patients, 24 males and 18 females, who were admitted to the Nebraska Psychiatric Institute with a diagnosis of schizophrenia. The age range of the sample was from 20 to 39 years with all patients rating the definition of chronic schizophrenia according to DSM-111. Patients were tested in the present study while on antipsychotic medications. All patients were administered both the CT scan, which was analyzed using the methods of Weinberger and his associates (1979) and the Luria-Nebraska Neuropsychological Battery. Using normative data previously published in the literature, each CT scan was classified as normal or abnormal. Using objective rules of interpretation given in the paper, the Battery was 81% accurate in determining the presence of ventricular enlargement. The Battery was also 90% accurate in identifying the presence or absence of sulcal enlargement. The implications of the present results for the use of psychological testing as a possible screening device for CT scans in a psychiatric population is discussed. Also, the limitations of the methods used in this paper are discussed as well as their advantages.

Trait analyses of the Luria-Nebraska Intellectual Processes, Motor Functions, and Memory Scales.

Trait analyses of the Luria-Nebraska's Intellectual Processes, Motor Functions, and Memory Scales were performed using multitrait-multimethod procedures and confirmatory factor analysis. Three measures each of intellectual, motor, and memory functions were administered to 161 neuropsychiatric patients. Intellectual scales (viz., Luria-Nebraska and WAIS-R) were found to have convincing discriminant properties, but motor and memory measures demonstrated visibly less such robustness. Confirmatory factor analyses supported a three-factor model of the 9 x 9 matrix, in which each of the three Luria-Nebraska scales serves as a marker for the factors. Issues related to the neuropsychological constructs, test construction, and construct validity of measurement procedures employed in clinical neuropsychology are discussed.

WAIS-R factor and performance on the Luria-Nebraska's Intelligence, Memory, and Motor Scales: a canonical model of relationships.

The pattern and level of performance on the WAIS-R and the Luria-Nebraska's Intelligence, Memory, and Motor Scales were examined for 93 neurologically impaired adults. Maximum likelihood factor analyses of the WAIS-R indicated the presence of strongly correlated (.72) Verbal Comprehension and Perceptual Organization dimensions. Comparisons of these factors to those of the standardization group revealed an acceptable level of similarity (.94) for Verbal Comprehension, but not for Perceptual Organization (.53). Canonical correlations between WAIS-R factor scores and the three Luria-Nebraska scaled scores accounted for 82% of the total variance. Each set of procedures evidently is indexing the same theoretical constructs. Implications of these findings for our understanding of the measurement models that underlie clinical neuropsychology are discussed.

Apolipoproteins (apoproteins) and LPL variation in Mennonite populations of Kansas and Nebraska.

Apoproteins (also known as apolipoproteins) have been studied extensively because of their role in lipid transport, association between specific genotypes and elevated serum lipid levels, and increased risk of heart disease. There is considerable genetic variation in the geographic distributions of these markers, with a north-south cline of the APOE*4 allele observed in Europe by Lucotte et al. ([1997] Hum Biol 69:253-262). This study compares the frequencies of seven APO (APOA1 -75 bp, APOA1 +83 bp, APOB Ins/Del, APOB XbaI, APOC3 SstI, and APOE) and LPL loci in Mennonite populations from Kansas and Nebraska. In total, 277 individuals were sampled from Goessel, Meridian, Garden View, and Lone Tree in 2002-2004. In addition, DNA samples that were collected in 1981 from Henderson, Nebraska, were genotyped for the seven APO and LPL loci. Of the seven APO and LPL loci tested, only one locus, APOB XbaI, departed significantly from Hardy-Weinberg equilibrium, with an unexpected excess of observed heterozygotes. The frequencies of the several APO loci are unique among the Mennonites, separating them from other European populations. A bidimensional scaling representation of Reynold's co-ancestry distances based on allelic frequencies of the seven APO and LPL markers in five Mennonite congregations fails to represent schematically the known patterns of fission. It is unclear whether the observed patterns are due to selection operating on these loci or whether genetic drift, small populations sizes, or a lack of statistical power of these biallelic loci distort the observed genetic relationship among congregations.

Evaluation of Parkinson's disease in entrants on the Nebraska State Parkinson's Disease Registry.

We examined a sample of individuals in the Nebraska State Parkinson's Disease Registry (NSPDR) to determine what proportion meets standard criteria for Parkinson's disease (PD). The NSPDR was established in 1996 in an effort to understand the high prevalence of PD in Nebraska. Only minimal demographic data are included for each entrant. Subjects enter the NSPDR by means of diagnosing physicians, pharmacists dispensing anti-PD medications and the patients themselves. A series of 356 registrants diagnosed between 1997 and 2001 were contacted and invited to participate in a case-control study. Medical records were reviewed by a single abstractor in a standard manner. When patients consented, history was filled in by interview. A subset of patients were examined by a movement disorders specialist, who assigned all patients a probability of PD. Where sufficient information was available, 78% of registrants were confirmed to have PD (i.e., percent probability > 50%), including 83% of the patients previously diagnosed by a neurologist. Tremor was an initial symptom in 72% of confirmed versus 39% of excluded cases, and resting tremor was present in 86% of those that were confirmed. The most frequent reasons for exclusion were drug-induced Parkinsonism, multiple systems atrophy, vascular disease, and essential tremor. Use of the NSPDR for epidemiologic study requires careful review of the data set before assignment of cases. When histories are compiled in a standardized, comprehensive manner, the necessity for actual patient examinations can be minimized.
