Clinical Evaluation Of Dietary Modification For Treatment Of Spontaneous Chronic Kidney Disease In Cats, S Ross, C Osborne, Claudia Kirk, S Lowry, L Koehler, D Polzin Sep 2006

Clinical Evaluation Of Dietary Modification For Treatment Of Spontaneous Chronic Kidney Disease In Cats, S Ross, C Osborne, Claudia Kirk, S Lowry, L Koehler, D Polzin

Claudia A Kirk

Objective-To determine whether a renal diet modified in protein, phosphorus, sodium, and lipid content was superior to an adult maintenance diet in minimizing uremic episodes and mortality rate in cats with stage 2 or 3 chronic kidney disease (CKD). Design-Double-masked, randomized, controlled clinical trial. Animals-45 client-owned cats with spontaneous stage 2 or 3 CKD. Procedures-Cats were randomly assigned to an adult maintenance diet (n = 23 cats) or a renal diet (22) and evaluated trimonthly for up to 24 months. Efficacy of the renal diet, compared with the maintenance diet, in minimizing uremia, renal-related deaths, and all causes of death was ...


Reticulocyte Indices In A Canine Model Of Nutritional Iron Deficiency, Michael Fry, Claudia Kirk May 2006

Reticulocyte Indices In A Canine Model Of Nutritional Iron Deficiency, Michael Fry, Claudia Kirk

Claudia A Kirk

BACKGROUND: Reticulocyte indices, especially reticulocyte hemoglobin content (CH retic), have shown promise as markers of iron deficiency (ID), but there have been no prospective investigations of reticulocyte indices in experimental models of ID. OBJECTIVES: The objective of this study was to compare reticulocyte indices with conventional hematologic and biochemical indices as markers of ID in dogs. METHODS: Iron deficiency was induced in 7 dogs by feeding an iron-deficient diet, and corrected by restoring dietary iron and by giving iron parenterally. Blood samples were collected at weekly intervals. Results of hematologic and biochemical tests were compared using t-tests and receiver operator ...


Comparison Of A Low Carbohydrate-Low Fiber Diet And A Moderate Carbohydrate-High Fiber Diet In The Management Of Feline Diabetes Mellitus, N Bennett, D Greco, M Peterson, Claudia Kirk, M Mathes, M Fettman Mar 2006

Comparison Of A Low Carbohydrate-Low Fiber Diet And A Moderate Carbohydrate-High Fiber Diet In The Management Of Feline Diabetes Mellitus, N Bennett, D Greco, M Peterson, Claudia Kirk, M Mathes, M Fettman

Claudia A Kirk

This study compared the effects of a moderate carbohydrate-high fiber (MC-HF) food and a low carbohydrate-low fiber (LC-LF) food on glycemic control in cats with diabetes mellitus. Sixty-three diabetic cats (48 male castrated, 15 female spayed) were randomly assigned to be fed either a canned MC-HF (n = 32) food or a canned LC-LF (n = 31) food for 16 weeks. Owners were blinded to the type of diet fed. CBC, urinalysis, serum chemistry panel, fructosamine concentration and thyroxine concentration were determined on initial examination, and a complete blood count, serum chemistry panel, urinalysis and serum fructosamine concentration were repeated every 4 ...

Primary Hair Growth In Dogs Depends On Dietary Selenium Concentrations, S Yu, K Wedekind, Claudia Kirk, R Nachreiner

Selenium (Se) plays an important role in hair growth. The objective of this study was to investigate the effect of dietary selenium concentration on hair growth in dogs. Thirty-six beagles were stratified into six groups based on age, gender and body condition score. The dogs were fed a torula yeast-based canned food for 3 weeks. Then the dogs were fed varying amounts of selenium supplied as selenomethionine for an additional 24 weeks. Analysed selenium concentrations in the experimental foods for the six groups were 0.04, 0.09, 0.12, 0.54, 1.03 and 5.04 mg/kg dry ...


Prevalence And Risk Factors For Obesity In Adult Dogs From Private Us Veterinary Practices, E Lund, P Armstrong, Claudia Kirk, J Klausner Dec 2005

Prevalence And Risk Factors For Obesity In Adult Dogs From Private Us Veterinary Practices, E Lund, P Armstrong, Claudia Kirk, J Klausner

Claudia A Kirk

Using a cross-sectional study design, the prevalence of overweight and obesity in dogs over 1 year of age seen by US veterinarians during 1995 was determined. Risk factors for overweight and obesity were also determined from the following variables: age, breed, gender, body condition score, food type, reported concurrent disease, and geographic region. Thirty-four percent of adult dogs (n=21,754) were overweight or obese. From multivariate analyses, overweight dogs were more likely to be older, of certain breeds (Cocker Spaniel, Labrador Retriever, Dalmatian, Dachshund, Rottweiler, Golden Retriever, Shetland Sheepdog, Mixed-breed), neutered, and to consume a semi-moist food as their ...


Effects Of Sodium Chloride On Selected Parameters In Cats, Claudia Kirk, D Jewell, S Lowry Dec 2005

Effects Of Sodium Chloride On Selected Parameters In Cats, Claudia Kirk, D Jewell, S Lowry

Claudia A Kirk

This study used 36 cats with varying renal insufficiency and physiologic status to evaluate the effect of a food high in sodium chloride (HSC) compared with a low sodium chloride (LSC) food on selected blood parameters and blood pressure. Cats eating the HSC food had an increase in serum creatinine, urea nitrogen, and phosphorus compared with cats eating the LSC food. Also, cats eating the HSC food had increased fractional excretion of calcium and increased fractional shortening during cardiac contraction. There was no effect of food on systolic, diastolic, or mean arterial pressure.
