Serum symmetric dimethylarginine concentrations in enalapril- or telmisartan-treated dogs with proteinuric chronic kidney disease.

Introduction: Renin-angiotensin-aldosterone system inhibition (RAASi) reduces intraglomerular pressure and is a standard therapy for dogs with proteinuric chronic kidney disease (CKD). RAASi can acutely decrease glomerular filtration rate (GFR); however, its effects on the marker of GFR serum symmetric dimethylarginine (SDMA) concentration in dogs have not been specifically evaluated. The objective of this study was to evaluate changes, relative to pretreatment values, in serum SDMA concentrations in dogs with proteinuric CKD receiving RAASi therapy.

Association of four differently processed diets with plasma and urine advanced glycation end products and serum soluble receptor for advanced glycation end products concentration in healthy dogs.

Advanced glycation end products (AGEs), formed via the Maillard reaction (MR) during processing of foods, have been implicated in inflammatory and degenerative diseases in human beings. Cellular damage is primarily caused by AGE binding with the receptor for AGEs (RAGE) on cell membranes. An isoform of RAGE, soluble RAGE (sRAGE), acts as a decoy receptor binding circulating AGEs preventing cellular activation.

Uroliths composed of antiviral compound GS-441524 in 2 cats undergoing treatment for feline infectious peritonitis.

Feline infectious peritonitis (FIP) historically has been a fatal disease in cats. Recent unlicensed use of antiviral medication has been shown to markedly improve survival of this infection. An 8-month-old female spayed domestic short-haired cat undergoing treatment for presumptive FIP with the antiviral nucleoside analog GS-441524 developed acute progressive azotemia.

Chylothorax secondary to subcutaneous cervical lipoma in a dog.

An 8-year-old male neutered American English Coonhound was presented for a 2-day history of increased respiratory effort and rate with an occasional cough. Thoracic radiographs noted pleural effusion, which was chylous based on cytological and chemical evaluation. The dog also had a 2-year history of a slow growing fatty mass in the right cervical region.

d,l-Methionine in combination with amoxicillin-clavulanic acid successfully dissolves spontaneously occurring infection-induced struvite urocystoliths in dogs: a pilot study.

Objective: To determine the efficacy and safety of a urinary acidifier (d,l-methionine [Methio-Form]) and an antimicrobial agent (amoxicillin-clavulanic acid [Clavamox]) without changing diet for dissolving infection-induced struvite urocystoliths in dogs.

Animals: 14 dogs were recruited for this prospective study; 11 completed it and 3 dogs withdrew due to inability of the owners to administer the treatment (n = 2) or refusal of treatment by the dog (1).

Procedures: All dogs were administered d,l-methionine (approx initial dose of 75 mg/kg, PO, q 12 h) and amoxicillin-clavulanic acid (22 mg/kg, PO, q 12 h) based on urine culture and sensitivity.

Weight measurements result in improved accuracy and precision in preparation of cooked homemade diets for dogs.

Objective: Accurate measurement of ingredients for cooked homemade diets helps ensure diets are complete and balanced. Studies have demonstrated measuring dry dog food with measuring cups results in significant inaccuracy. Therefore, measuring ingredients by volume when preparing these diets may be inaccurate.

Urinary Tract Infections Treatment/Comparative Therapeutics.

Urinary tract infection (UTI) is commonly encountered in small animal general practice. Within the past 5 years, there have been changes to terminology, such as the renaming of asymptomatic bacteriuria to subclinical bacteriuria, as well as paradigm shifts in the management of UTI. In general, there is an emphasis for responsible antimicrobial stewardship and selecting treatment based on urine culture and sensitivity and treating symptomatic bacterial UTI with a shorter duration of antimicrobials.

Management of a urethral tear with porcine small intestinal submucosa-augmented urethroplasty and balloon dilation for subsequent urethral stricture in a cat.

Case Description: As a result of vehicular trauma, a 3-year-old neutered male domestic shorthair cat sustained luxation of the sacrocaudal joint and a urethral tear.

Clinical Findings: Retrograde contrast urethrocystography revealed a urethral tear at the level of the ischiatic tuberosity. Conservative treatment for 7 days with a urethral catheter was unsuccessful.

Effect of a Leucine/Pyridoxine Nutraceutical on Caloric Intake and Body Composition of Obese Dogs Losing Weight.

The aim of this 29-week randomized, positively and negatively controlled study was to investigate whether a nutraceutical containing 1 g leucine and 13 mg pyridoxine can enhance weight loss while maintaining lean muscle mass in obese dogs. Twenty-four healthy, 2-year-old beagles were initially divided into obesification ( = 18) or ideal body weight groups ( = 6). After obesification, the 18 dogs were divided into three weight loss groups and fed one of the following over 12 weeks: nutraceutical with canned adult diet (CAD; ObN), placebo with CAD (ObP), or a canned therapeutic weight loss diet (WLD).

Lateral rhinotomy and coblation for treatment of a nasal hamartoma in a dog.

Case Description: A 4-year-old spayed female French Bulldog was referred for treatment of a suspected right-sided nasal angiofibroma associated with a 4-month history of unilateral nasal discharge and stertor.

Clinical Findings: The dog appeared healthy other than right-sided mucoid debris and decreased airflow through the right naris. The dog was anesthetized, and a large intranasal mass was observed obstructing the right nasal passage and abutting the nasal septum.

Pyloric outflow obstruction secondary to sclerosing encapsulating peritonitis in a dog.

A 6-year-old, male neutered mixed breed dog was presented emergently with a three-week history of hyporexia, vomiting, diarrhoea and weight loss. Upon examination, the patient was dull, had generalised muscle atrophy, moderate abdominal pain and a mild amount of peritoneal effusion. A fluid-filled, distended, corrugated small bowel with marked gastroparesis and moderate peritoneal effusion was noted on abdominal ultrasonography.

Quantified water intake in laboratory cats from still, free-falling and circulating water bowls, and its effects on selected urinary parameters.

Objectives: The study objectives were to determine if the method of water presentation (still [S], circulating [C] or free-falling [FF] bowl systems) influences daily water consumption in cats in a controlled environment, and whether differences in water intake affect urine relative super saturation (RSS) for calcium oxalate and struvite, urine specific gravity (USG), urine osmolality (Uosmol) and urine volume.

Methods: Sixteen healthy laboratory cats fed a dry diet were individually housed with urine collection systems. Each cat underwent a randomized 2 week crossover period with all bowl systems, allowing a 1 week acclimation period between each crossover.

Evaluation of three herbal compounds used for the management of lower urinary tract disease in healthy cats: a pilot study.

Objectives: Lower urinary tract disease (LUTD) occurs commonly in cats, and idiopathic cystitis (FIC) and urolithiasis account for >80% of cases in cats <10 years of age. Although several strategies have been recommended, a common recommendation is to induce dilute urine resulting in more frequent urination and to dilute calculogenic constituents. In addition to conventional therapy using modified diets, traditional Chinese and Western herbs have been recommended, although only one - choreito - has published data available.

One Health Solutions to Obesity in People and Their Pets.

Despite the high prevalence of overweight and obesity in the human and companion animal populations, and the global trends for increasing numbers of affected people and pets, there are few successful interventions that are proven to combat this complex multifactorial problem. One key strategy involves effective communication between human and veterinary healthcare professionals with patients and clients about obesity. In human healthcare, the focus of communication should be on physical activity as part of overall health and wellbeing, rather than assessment of the body mass index; clinical examination of patients should record levels of physical activity as a key 'vital sign' as part of their assessment.

Povidone iodine sclerotherapy for treatment of idiopathic renal hematuria in two dogs.

CASE DESCRIPTION A 6-year-old spayed female Great Pyrenees (dog 1) and a 2-year-old spayed female German Shepherd Dog (dog 2) were evaluated because of gross hematuria of 5 and 2 months' duration, respectively. CLINICAL FINDINGS In both dogs, coagulation times were within reference limits, results of aerobic bacterial culture of urine samples were negative, echogenic debris could be seen within the urinary bladder ultrasonographically, and hematuric urine could be seen exiting the right ureterovesicular junction, with grossly normal urine exiting the left ureterovesicular junction, during cystoscopy. A diagnosis of idiopathic renal hematuria was made in both dogs.

ACVIM Small Animal Consensus Recommendations on the Treatment and Prevention of Uroliths in Dogs and Cats.

In an age of advancing endoscopic and lithotripsy technologies, the management of urolithiasis poses a unique opportunity to advance compassionate veterinary care, not only for patients with urolithiasis but for those with other urinary diseases as well. The following are consensus-derived, research and experience-supported, patient-centered recommendations for the treatment and prevention of uroliths in dogs and cats utilizing contemporary strategies. Ultimately, we hope that these recommendations will serve as a foundation for ongoing and future clinical research and inspiration for innovative problem solving.

Feline Calcium Oxalate Urolithiasis: Risk factors and rational treatment approaches.

Practical Relevance: Uroliths occur commonly in the bladder and/or urethra of cats and can be lifethreatening if urethral obstruction occurs. Calcium oxalate accounts for 40-50% of urocystoliths and these stones are not amenable to medical dissolution; therefore, removal by surgery or minimally invasive techniques is required if uroliths must be treated. Medical protocols for prevention involve decreasing urine saturation for minerals that form uroliths.

Cryopreserved platelet concentrate transfusions in 43 dogs: a retrospective study (2007-2013).

Objective: To clinically characterize a group of thrombocytopenic dogs that received cryopreserved platelet concentrate (cPC) transfusion, assess efficacy of cPC treatment in improving patient outcome, and compare treated dogs to a control population of thrombocytopenic dogs that did not receive cPC transfusions.

Design: Retrospective study.

Setting: University teaching hospital.

Prevalence of asymptomatic urinary tract infections in morbidly obese dogs.

Background. Obesity has reached epidemic proportions in dogs and, as in humans, cost of care has increased due to associated comorbidities. In humans, asymptomatic urinary tract infections (UTI) may be more prevalent in the obese.

Evaluation of two raw diets vs a commercial cooked diet on feline growth.

Objectives The objective of this study was to determine if two raw feline diets were nutritionally adequate for kittens. Methods Twenty-four 9-week-old kittens underwent an Association of American Feed Control Officials' (AAFCO) 10 week growth feeding trial with two raw diet groups and one cooked diet group (eight kittens in each). Morphometric measurements (weight, height and length), complete blood counts, serum chemistry, whole blood taurine and fecal cultures were evaluated.

Apparent nutrient digestibility of two raw diets in domestic kittens.

Objectives: The aim of the study was to evaluate overall dry matter, organic matter, crude protein, crude fat and gross energy digestibility of a feline commercial raw diet and a homemade raw diet compared with a canned, heat-processed diet.

Methods: Six domestic shorthair kittens (20-28 weeks old) were fed three different diets in a Latin square crossover design. Diet A was a commercially available, canned, heat-processed diet.

Relationship of adiponectin and its multimers to metabolic indices in cats during weight change.

Adiponectin is an important anti-inflammatory hormone secreted from adipose tissue. The high-molecular-weight form of adiponectin (HMW) closely correlates with insulin sensitivity in human beings. This study uses a novel method of size-exclusion gel chromatography combined with enzyme-linked immunosorbent assay to measure HMW feline adiponectin and determine its relationship to leptin, cholesterol, and insulin sensitivity as cats gain and lose weight.
