Proximal versus distal influences on underrepresented minority students pursuing health professional careers.
(57/189)
The Health Careers Opportunities Program (HCOP) at Creighton University provides an important illustration of the short- and long-term successes of pipeline programming. The Pipeline to Success program at Creighton University provides exposure and enrichment activities to participants beginning in middle school and continuing through a one-year postbaccalaureate component in order to ensure that they are knowledgeable about health professional careers and competitive in applying for these training programs. This study hypothesized that the enrichment activities experienced by participants would have the additional benefit of providing indirect or distal influences to motivate participants to meet their career goals. In partial support of this hypothesis, a MANOVA demonstrated that the middle-school participants demonstrated a different pattern of influence from the other program components. Results indicate that as participants progressed through the Pipeline to Success HCOP at Creighton University, the program resources impacted their desire to pursue health professional careers in addition to positively preparing them for health professional training programs. We conclude that these findings have particular importance for planning and implementing student education programs. (+info)

Cigarette smoking, familial hematopoietic cancer, hair dye use, and risk of t(14;18)-defined subtypes of non-Hodgkin's lymphoma.
(59/189)
Some evidence suggests that smoking, a family history of hematopoietic cancer, and use of hair dyes are associated with t(14;18)-defined subsets of non-Hodgkin's lymphoma (NHL) in men. To further evaluate these associations and to expand them to women, the authors determined t(14;18)(q32;q21) status by fluorescence in situ hybridization in 172 of 175 tumor blocks from a population-based case-control study conducted in Nebraska during 1983-1986. Exposures in 65 t(14;18)-positive cases and 107 t(14;18)-negative cases were compared with those among 1,432 controls. Odds ratios and 95% confidence intervals were calculated using polytomous logistic regression. Among men, smoking was not associated with risk of t(14;18)-positive or -negative NHL. Among women who had ever smoked cigarettes, there was an association with risk of t(14;18)-negative NHL (odds ratio (OR) = 1.9, 95% confidence interval (CI): 1.1, 3.3) but not t(14;18)-positive NHL (p-difference = 0.01). The risks for t(14;18)-negative NHL among women increased with longer duration (>30 years: OR = 2.1, 95% CI: 1.1, 4.1) and early initiation (age +info)
Holocene coccidioidomycosis: Valley Fever in early Holocene bison (Bison antiquus).
(60/189)
Early Holocene bison mandibles (Bison antiquus) from Nebraska, ca. 8500 y ago, were examined with a variety of modern histotechnological procedures and staining techniques. A pathological, anatomical diagnosis of moderately severe, locally extensive, mandibular osteomyelitis with intralesional spherules morphologically consistent with fungal pathogens in the genus Coccidioides was made. The modern distribution of the organisms in North America is restricted to the arid Southwest. This implies either the fossil home range of the fungi was larger than it is today or fossil bison migrated between endemic and nonendemic foci during the early Holocene. (+info)
Healthy Start screens for depression among urban pregnant, postpartum and interconceptional women.
(61/189)
OBJECTIVE: To examine perinatal depression in north and northeast Omaha, NE. METHODS: The records of a sample of 119 randomly selected clients from Omaha Healthy Start (OHS) were reviewed. Three screening instruments were employed to identify women with depression: they were asked whether they were depressed (DQ); they received the Edinburgh Postpartum Depression Scale (EPDS) and/or the Beck Depression Inventory (BDI). RESULTS: The number of women with depressive symptoms identified by each technique varied from: DQ (16.8%), EPDS (16%) and BDI (7.6%). The three methods identified three subpopulations of women with different maternal and child health risk profiles reflected by their responses on an OHS-developed Maternal and Child Health Risk Assessment Tool. CONCLUSION: In combination, these simple techniques identified depressed women with different risk profiles who would have been missed using a single approach exclusively. (+info)
Hepatitis-C prevalence in an urban native-American clinic: a prospective screening study.
(62/189)
BACKGROUND: Native-American populations are disproportionately burdened by chronic liver disease, and the prevalence of hepatitis C (HCV) in native Americans is unknown. PURPOSE: To determine the prevalence of hepatitis C in a local native-American population via a prospective screening study. PROCEDURES: Two-hundred-forty-three native Americans (161 females/82 males) using an urban clinic and representing > 30 tribes from across the United States were screened. Mean age was 41 +/- 1 years. Hepatitis-C screening was by anti-HCV with confirmation by HCV RNA. A questionnaire assessed potential risk factors for HCV. FINDINGS: Anti-HCV antibodies were found in 11.5% (95% CI: 7.5-15.5%). HCV RNA was present by polymerase chain reaction (PCR) in 8.6% (95% CI: 5.1-12.1%) and was more common in males [13.4% (95% CI: 6.0-20.8%)] than females [6.2% (95% CI: 2.5-9.9%)]. The most common potential risk factors for chronic HCV infection were intravenous (IV) drug or cocaine use (p < 0.0001), tattoos > 5 years old (p < 0.0001) and having a sexual partner with HCV (p = 0.0063). CONCLUSION: HCV prevalence is higher in an urban native-American clinic population than reported in the general U.S. population. Use of IV drugs is the most prevalent risk factor, but tattoos and sexual transmission may also be important. (+info)
An evaluation of the relative efficacy of tulathromycin for the treatment of undifferentiated fever in feedlot calves in Nebraska.
(63/189)
A field trial was performed under commercial feedlot conditions in central Nebraska to assess the relative efficacy of tulathromycin (TULA) to florfenicol (FLOR) for the treatment of undifferentiated fever (UF) in feedlot calves that did not receive a metaphylactic antimicrobial or vaccines/bacterins containing Mannheimia haemolytica or Histophilus somni at feedlot arrival by comparing animal health, feedlot performance, and carcass characteristic variables. Two hundred recently weaned, auction market derived, crossbred beef calves that met the study-specific case definition of UF were randomly allocated in a 1:1 ratio to 1 of 2 experimental groups as follows: TULA, which received tulathromycin administered subcutaneously at the rate of 2.5 mg/kg body weight (BW) once at the time of allocation; or FLOR, which received florfenicol administered subcutaneously at the rate of 40 mg/kg BW once at the time of allocation. In terms of animal health, the first UF relapse (RR = 0.65), overall mortality (RR = 0.33), and BRD mortality (RR = 0.29) rates in the TULA group were significantly (P < 0.05) lower than in the FLOR group. There were no significant (P > or = 0.05) differences between the TULA and FLOR groups for the other animal health variables measured. There was no significant (P > or = 0.05) difference in average daily gain between the TULA and FLOR groups. There were no significant (P > or = 0.05) differences in the overall distributions of quality grade and yield grade between the experimental groups; however, a significantly (P < 0.05) higher proportion of carcasses in the TULA group graded yield grade USDA-4 as compared with the FLOR group. In the economic analysis, the benefits observed resulted in an economic advantage of $52.50 USD/animal in the TULA group due to lower first UF relapse and overall mortality rates, even though the occurrence of yield grade USDA-4 carcasses increased and the initial UF treatment cost was higher.

Types of alcoholic beverages usually consumed by students in 9th-12th grades--four states, 2005.
(64/189)
Excessive alcohol consumption contributes to approximately 4,500 deaths among underage youths in the United States each year (e.g., from homicides, motor-vehicle crashes, and suicides) and an average of 60 years of life lost per death. However, little is known about the specific types of alcoholic beverages consumed by youths. These data are important because numerous evidence-based strategies for reducing underage drinking rates are beverage-specific, including increasing alcohol excise taxes and increasing restrictions on the distribution and sale of alcoholic beverages. To examine types of alcoholic beverages usually consumed by students in 9th-12th grades, CDC analyzed 2005 Youth Risk Behavior Survey (YRBS) data from the four state surveys that included a question on the type of alcohol consumed (Arkansas, Nebraska, New Mexico, and Wyoming). This report describes the results of that analysis, which indicated that liquor (e.g., bourbon, rum, scotch, vodka, or whiskey) was the most prevalent type of alcoholic beverage usually consumed among students in 9th-12th grades who reported current alcohol use or binge drinking. These findings suggest that considering beverage-specific alcohol consumption by youths is important when developing alcohol-control policies, specifically those related to the price and availability of particular types of alcoholic beverages.
