Association Of Season And Pasture Grazing With Blood Hormone And Metabolite Concentrations In Horses With Presumed Pituitary Pars Intermedia Dysfunction, N Frank, Sarah Elliott, K Chameroy, Ferenc Toth
Background: Pituitary pars intermedia dysfunction (PPID) is a risk factor for pasture-associated laminitis, which follows a seasonal pattern. Hypothesis: Hormonal responses to season differ between PPID and unaffected horses. Animals: Seventeen horses aged 8-30 years (14 horses ≥ 20 years of age). Methods: Longitudinal observational study. Blood was collected monthly from August 2007 until July 2008 after pasture grazing and again after overnight stall confinement. Blood hormone and metabolite concentrations were measured and pasture grass samples were analyzed to determine carbohydrate content. Analysis of variance analysis for repeated measures was performed. Results: Mean ACTH concentrations varied significantly over time (P < .001), with higher concentrations detected in August, September, and October compared with November-April. Pasture × time effects were detected for glucose and insulin concentrations, with peaks observed in September. Horses were retrospectively allocated to PPID (n = 8) and control (n = 9) groups on the basis of plasma ACTH concentrations. Changes in insulin concentrations over time differed in the PPID group when compared with the control group. Insulin concentrations were positively correlated with grass carbohydrate composition. Conclusions and Clinical Importance: PPID did not affect the timing or duration of the seasonal increase in ACTH concentrations, but higher values were detected in affected horses. Insulin concentrations differed between groups, but hyperinsulinemia was rarely detected. Glucose and insulin concentrations peaked in September when horses were grazing on pasture, which could be relevant to the seasonal pattern of laminitis.
Risk Of Cancer In Patients With Biopsy-Proven Giant Cell Arteritis., 2009 Government of South Australia, SA Health
Risk Of Cancer In Patients With Biopsy-Proven Giant Cell Arteritis., Catherine Hill, A Cole, M Rischmueller, T Dodd, M Coleman, G Tucker, Pj Roberts-Thomson
Objective. Results of previous studies investigating the association between GCA and malignancy are conflicting. We performed a study of the risk of cancer in patients with biopsy-proven GCA. Methods. Patients with biopsy-proven GCA were identified from pathology reports of temporal artery biopsies from the major pathology laboratories in South Australia (SA). All subjects with biopsy-proven GCA were linked to the SA Cancer Registry to identify cases of cancer until 31 December 2006. Standardized incidence ratios (SIRs) for cancer were determined using the age- and gender-specific rates for SA. Results. There were 226 cases of biopsy-proven GCA (163 females and 63 ...

The Ces-D In Chinese American Women: Construct Validity, Diagnostic Validity For Major Depression, And Cultural Response Bias., Z Li, M Hicks
Madelyn Hsiao-Rei Hicks
Previous studies of the Center for Epidemiologic Studies Depression Scale (CES-D) in Chinese Americans describe internal reliability and factor structure. We report CES-D construct validity and diagnostic validity for major depression in a probability sample of 168 community-dwelling Chinese American women. Internal consistency was satisfactory (Cronbach's alpha=0.86). Good construct validity was indicated by significantly higher mean CES-D scores for respondents who reported lower social support, worse self-perceived general health, or stressful life events, including intimate partner violence. Cultural response bias was found, with positively-stated CES-D items (e.g. "I was happy") producing higher depression scores in immigrants ...
Targeted Maximum Likelihood Estimation Of The Parameter Of A Marginal Structural Model, 2009 Johns Hopkins University
Targeted Maximum Likelihood Estimation Of The Parameter Of A Marginal Structural Model, Michael Rosenblum, Mark Van Der Laan
Targeted maximum likelihood estimation is a versatile tool for estimating parameters in semiparametric and nonparametric models. We work through an example applying targeted maximum likelihood methodology to estimate the parameter of a marginal structural model. In the case we consider, we show how this can be easily done by clever use of standard statistical software. We point out differences between targeted maximum likelihood estimation and other approaches (including estimating function based methods). The application we consider is to estimate the effect of adherence to antiretroviral medications on virologic failure in HIV positive individuals.

OBJECTIVE: This retrospective study was conducted to evaluate the outcome for cattle with diaphyseal fractures of the femur, but not including capital physeal injuries. METHODS: Sources of information were medical records of cattle having a definitive diagnosis of diaphyseal femoral fractures and telephone survey of owners. RESULTS: Medical records for 26 cattle with femoral fracture were found; of the 20 aged less than 2 months, 15 were treated surgically, 4 conservatively (stall rest) and 1 was euthanased without treatment. The surgical treatment varied according to the configuration of the fracture and the surgeon's experience. Surgery for mid-diaphyseal fractures had ...
Enhancing Interprofessional Collaboration And Community-Based Participatory Research Through Technology, 2009 Lakehead University - Orillia Campus
Enhancing Interprofessional Collaboration And Community-Based Participatory Research Through Technology, Kevin Willison, Tom Palos
Kevin D Willison
Effective community development to maximize a given area’s potential requires strategies that enhance interprofessional collaboration (IPC) and community-based participatory research (CBPR). The role technology has to enable this has to date received little attention. Drawing from such diverse fields as Sociology and Public Health, this cross-disciplinary article provides an overview of what CBPR and IPC are and how it may be practically implemented via use of technology so as to improve knowledge mobilization and, in turn, effective decision making. CBPR, IPC, sociology and public health all share a common theme - community empowerment. To mobilize and maximize empowerment, knowledge transfer ...

Reported Changes In Students’ Alcohol Consumption Following A Brief Education Of What Constitutes A Standard Drink, Dessa Bergen-Cico, Jason Kilmer
Dessa Bergen-Cico, Ph.D.
Intercept surveys were conducted with 149 college students each asked to record their alcohol consumption for the previous 2 weeks using the Timeline Follow-back (TLFB method). Immediately following completion of the pretest TLFB alcohol survey the students were presented with brief educational information defining what constitutes one standard drink. Students then completed a new posttest TLFB survey and re-recorded the number of drinks they had in the previous 2 weeks. Among drinkers the majority, 55 percent, reported an increased number of drinks in response to the standard drink education information they received. Posteducation TLFB survey records were significantly higher than ...

Canine Synovial Myxoma: 39 Cases, Linden Craig, Pm Krimer, Aj Cooley
Linden E. Craig DVM, Ph.D., DACVP, College of Veterinary Medicine
This report describes the signalment, clinical findings, gross appearance, histological and immunohistochemical characteristics, and behavior of 39 cases of canine synovial myxoma. Large-breed middle-aged dogs—especially, Doberman Pinschers and Labrador Retrievers—were most commonly affected. The stifle and digit were the most common sites. Grossly, the tumors were composed of gelatinous nodules that often filled the joint cavity and exuded viscous fluid on cut section. In 12 cases (31%), radiographic bony lysis or grossly invasive growth was noted clinically. Histologically, the nodules were sparsely cellular and composed of stellate to spindle cells suspended in an abundant myxomatous matrix. By immunohistochemistry ...
Backward Estimation Of Stochastic Processes With Failure Events As Time Origins, 2009 University of Washington - Seattle Campus
Backward Estimation Of Stochastic Processes With Failure Events As Time Origins, Kwun Chuen Gary Chan, Mei-Cheng Wang
Kwun Chuen Gary Chan
Stochastic processes often exhibit sudden systematic changes in pattern a short time before certain failure events. Examples include increase in medical costs before death and decrease in CD4 counts before AIDS diagnosis. To study such terminal behavior of stochastic processes, a natural and direct way is to align the processes using failure events as time origins. This paper studies backward stochastic processes counting time backward from failure events, and proposes one-sample nonparametric estimation of the mean of backward processes when follow-up is subject to left truncation and right censoring. We will discuss benefits of including prevalent cohort data to enlarge ...

Examining The Root Cause Of Surrogate Conflicts In The Icu And General Wards, 2009 Bond University
Examining The Root Cause Of Surrogate Conflicts In The Icu And General Wards, Katrina Bramstedt, Allison Rubin
Katrina A. Bramstedt
This study is an analysis of surrogate-focused ethics consultations in the Intensive Care Unit (ICU) and the general wards (Ward) of a large community hospital in Northern California. We identified the major themes of surrogate-focused ethics consultations to better understand the root cause of surrogate conflicts, and identified the similarities and differences between surrogate-based conflicts in the two settings. Consults requested because the surrogate had desires that conflicted with the physician’s medical opinion of ‘best interest’, or cases involving surrogates not upholding a patient’s known values reflected the root cause of the majority of surrogate conflicts (72.7 ...
