    Title Factors Associated with Occurrence and Recovery of Nonambulatory Dairy Cows in the United States.
    Date July 2008
    Journal Journal of Dairy Science
    Excerpt

    The primary objective of this study was to compare characteristics of US dairy operations that had one or more nonambulatory cows (unable to rise for any period of time) (cases) with operations that had no nonambulatory cows (controls) during 2004. A secondary objective was to describe factors associated with recovery of the last nonambulatory cow on the operation during 2004. Case dairy operations (n = 1,822) more often fed a total mixed ration [odds ratio (OR) = 2.0; confidence interval (CI): 1.1-3.4], produced more than 9,090 kg of milk (OR = 2.8; CI: 1.8-4.5), and were more likely to be of medium to large herd size (100 or more head of adult cows, OR = 3.7; CI: 2.2-6.2) compared with control dairies (n = 151). Compared with operations where the predominant flooring surface on which lactating cows stood or walked in winter was pasture, operations where pasture was not the predominant surface were at increased risk of having nonambulatory cows (OR = 4.7; CI: 2.2-10.2). Cows nonambulatory for less than 24 h were more likely to recover compared with cows nonambulatory for 24 h or more (OR = 3.0; CI: 2.0-4.4). Cows that received calcium, phosphorus, or potassium while non-ambulatory were more likely to recover (OR = 3.6; CI: 2.1-6.1) than cattle that did not receive these treatments. Cattle that were not repositioned periodically were more likely to recover (OR = 2.1; CI: 1.4-3.1), as were cattle that were not treated by a veterinarian before becoming nonambulatory (OR = 1.9; CI: 1.1-3.3). These findings are consistent with prolonged recumbency and prior history of health issues, respectively. Nonambulatory cattle with hypocalcemia were more likely to recover (OR = 6.0; CI: 3.4-10.7) compared with nonambulatory cows with all other causes of a nonambulatory condition (analyzed collectively as a single variable but including cancer, clinical mastitis, digestive conditions, metabolic imbalances, neurological problems, respiratory disease, other, unknown). The results of this study reveal that the majority of US dairy operations have at least one nonambulatory dairy cow over the course of a year. Additionally, individual animal factors associated with being nonambulatory may lead to improved identification and treatment of animals that are nonambulatory for a prolonged period. From the perspective of recovery, considering euthanasia is appropriate for cows that have been nonambulatory for more than 24 h.

    Title Quality Benchmarks in Undergraduate Psychology Programs.
    Date November 2007
    Journal The American Psychologist
    Excerpt

    Performance benchmarks are proposed to assist undergraduate psychology programs in defining their missions and goals as well as documenting their effectiveness. Experienced academic program reviewers compared their experiences to formulate a developmental framework of attributes of undergraduate programs focusing on activity in 8 domains: curriculum, assessment issues, student learning outcomes, program resources, student development, faculty characteristics, program climate, and administrative support. A continuum of performance was conceptualized for each attribute in each of the domains to characterize underdeveloped, developing, effective, and distinguished achievement for undergraduate programs. The authors hope to inspire a national conversation about program benchmarks in psychology in order to improve program quality, encourage more effective program reviews, and help optimally functioning programs compete more successfully for resources on the basis of their distinguished achievements.

    Title Design and Implementation of the United States National Animal Health Monitoring System 1995 National Swine Study.
    Date July 1998
    Journal Preventive Veterinary Medicine
    Excerpt

    The United States Department of Agriculture's National Animal Health Monitoring System 1995 National Swine Study was designed to estimate management, health and productivity parameters on pig operations in the United States. Sixteen major swine-producing states that accounted for nearly 91% of June 1, 1995 swine inventory and nearly three-fourths of United States swine producers were included in the study. In the initial phase of the study, National Agricultural Statistics Service enumerators collected information from 1477 producers involved in all phases of swine production (farrowing, nursery, and grower/finisher). Of these, 405 operations with > or = 300 finisher pigs (with at least one finisher pig > or = 54 kg) participated in the subsequent component of the study, which involved on-farm visits by state and federal veterinary medical officers and animal health technicians, and which concentrated on the grower/finisher phase of production. Of those eligible to take part in the second phase of the study, participation was higher among independent producers (48.3%) than among contract producers (15.3%). Participation was also higher among operations that used advanced record-keeping systems (such as record cards for individual breeding hogs or a computer-based record-keeping system). Thus, study results could have been influenced by response biases. As a biosecurity measure, 40.5 +/- 2.1% of operations restricted entry to employees only. For operations that permitted non-employees to enter the premises, relatively few enforced other biosecurity measures on visitors (0.4 +/- 0.1% required feed-delivery personnel and livestock handlers to shower before entering the premises; 3.3+/- 0.9% required a footbath; and 7.0 +/- 1.5% required feed-delivery personnel and livestock handlers not to have visited another operation with pigs on that day). The most common method of waste storage (used by 49.9 +/- 3.8% of operations with > or = 300 finisher pigs) was below-floor slurry or deep pit.

    Title Design and Implementation of the United States National Animal Health Monitoring System 1994-95 Cattle on Feed Evaluation, and an Evaluation of the Impact of Response Biases.
    Date September 1997
    Journal Preventive Veterinary Medicine
    Excerpt

    The 1994-95 Cattle on Feed Evaluation was a cooperative project (sponsored by the United States Department of Agriculture) involving Washington State University, state agricultural departments, and several agencies of the United States Department of Agriculture). The project focused on cattle-on-feed operations in 13 states that accounted for over 85% of the United States cattle on feed inventory. Participants were selected from National Agricultural Statistics Service list frames. Questionnaires were administered by telephone to operations with a one-time capacity of fewer than 1000 cattle; larger operations were visited twice to administer questionnaires. The participation rate for the first phase of the study was 56.7%. Ninety-one percent of eligible operations completed the second phase of the study. Data summarized from this national study can be used to profile management practices on cattle-feeding operations in the United States. Differences between participants and non-participants did not appear to be great. However, one does need to be mindful of the fact that a small percentage of the producers accounted for the vast majority of feedlot cattle marketed when interpreting the results.

    Title Health Status of Preweaned Dairy Heifers in the United States.
    Date September 1997
    Journal Preventive Veterinary Medicine
    Excerpt

    The first national estimates of mortality and morbidity for preweaned dairy heifers in the US were generated from monitoring heifers from 906 operations in 28 states prospectively using a daily diary card system. Results indicated that the cumulative mortality incidence risk from birth to 8 weeks of life was 6.3% with a peak of 1.9% during the first week of life. Season of birth was significantly associated with cumulative mortality incidence risk, and mortality risk was highest in the periods January to March and October to December. Cumulative incidence risk of diarrhea to 8 weeks of age was 24.6% with a peak of 15.4% during the second week of life. Diarrhea incidence risk varied by region, with the West having the highest incidence risk (30.5%) and the Northeast the lowest (19.2%), as well as by herd size, with the smallest herd size having the lowest reported incidence risk of diarrhea to 8 weeks of age (18.8%). Other reported 8 week cumulative disease incidence risks included listlessness, 10.0%; respiratory disease, 8.4%; dehydration, 4.1%; lameness or joint problems, 1.1%.

    Title The National Dairy Heifer Evaluation Project: a Profile of Heifer Management Practices in the United States.
    Date October 1994
    Journal Journal of Dairy Science
    Excerpt

    The National Dairy Heifer Evaluation Project was a cooperative, USDA-sponsored project involving state agricultural departments, the Cooperative Extension Service, the National Agricultural Statistics Service, and the Animal and Plant Health Inspection Service. A series of retrospective and prospective descriptive surveys using a multiple list and area frame sampling technique were conducted. Information collected pertained primarily to dairy neonates and replacement heifers. Much of the study was related to observational information on health and management characteristics that can be related to the animals' long-term physical and economic performance. The data reflect herds representing 78% of the national dairy cow population. Average herd size was 86 milking and dry cows and 66 heifers. Many characteristics of these herds reflect accepted and recommended practices in the area of dairy replacement management and nutrition. Data summarized in this national study can be utilized to evaluate the impact of management practices on dairy operations.

    Title Memory for Two Types of Spatial Location: Effects of Instructions, Age, and Format.
    Date June 1985
    Journal The American Journal of Psychology
    Excerpt

    Three experiments, with old persons (59-80 years) and college students (17-30 years) in Experiments 1 and 2 and with college students (17-24 years) in Experiment 3, investigated the differences between two types of spatial location memory: memory for the location of individual items in an array and memory for occupied, as opposed to unoccupied, locations in an array. Young persons performed better than old persons on both measures of location memory. However, an effect of instructions (intentional vs. incidental for spatial location) was consistently obtained for memory for occupied, as opposed to unoccupied, locations, whereas no effect of instructions was obtained for memory for individual item locations. In addition, item location memory was superior for objects as opposed to matched words (Experiment 2), whereas occupied location memory was not affected by presentation format (Experiments 2 and 3). These differences indicate that spatial memory is a complex process whose properties are affected by variations in stimulus characteristics and task demands. It was concluded that the distinction of Hasher and Zacks (1979) between automatic and effortful processes is not adequate for understanding spatial memory. A recognition of the complex nature of spatial processing suggests a resolution of discrepancies in the literature based upon differences in stimulus characteristics, task demands, and the effectiveness of task-appropriate mnemonic strategies.

    Title Cisplatin-induced Ototoxicity: Effect of Intratympanic Dexamethasone Injections.
    Date
    Journal Otology & Neurotology : Official Publication of the American Otological Society, American Neurotology Society [and] European Academy of Otology and Neurotology
    Excerpt

    HYPOTHESIS: Intratympanic (IT) application of dexamethasone will reduce ototoxicity associated with systemic cisplatin therapy. BACKGROUND: Cisplatin is a common chemotherapeutic drug often dose-limited by ototoxicity attributed to the formation of reactive oxygen and nitrogen species damaging critical inner ear structures. Steroids have been shown to reduce formation of reactive oxygen species and thus may reduce ototoxicity. In the present pilot study, we test this hypothesis by IT administration of dexamethasone in a novel murine model of cisplatin ototoxicity. METHODS: Click- and pure-tone-evoked auditory brainstem responses (ABRs) in young CBA/J mice were measured. The first phase consisted of a dosing study to identify the optimal cisplatin dose for ototoxicity. In the next phase, ABR thresholds were measured in cisplatin-treated mice after 5 days of IT injection of 24 mg/ml of dexamethasone in 1 ear and normal saline in the opposite ear to serve as controls. RESULTS: Intraperitoneal injection of 14 mg/kg of cisplatin induces significant hearing loss (click-evoked ABR threshold elevation = 12 +/- 7 dB, mu +/- standard error of the mean) with acceptable mortality (20%). The ears that received IT dexamethasone in cisplatin-treated mice had minimal ABR threshold shifts with the click, 8 and 16 kHz of stimuli. There was no significant difference between IT dexamethasone and IT saline ears at 32 kHz. CONCLUSION: IT dexamethasone protected the mouse ear against cisplatin-induced ototoxicity in a frequency-dependent manner. The present results suggest that IT dexamethasone may be a safe, simple, and effective intervention that minimizes cisplatin ototoxicity without interfering with the chemotherapeutic actions of cisplatin.
