Risk factors and impact of COVID-19-related clinic closures on the detection of gastrointestinal parasites in dogs, a cross-sectional study.

Infections with endoparasites, especially gastrointestinal helminths, are a common finding in client-owned dogs. The Community Practice section at the Ohio State University Veterinary Medical Center (OSU-VMC) follows Companion Animal Parasite Council, American Animal Hospital Association, and American Veterinary Medical Association guidelines for parasitology by recommending annual fecal analyses for dogs and prescribing year-round, broad-spectrum parasite preventatives. There is increasing interest in determining if parasite occurrence is changing in client-owned dogs.

Comparison of albumin, colloid osmotic pressure, von Willebrand factor, and coagulation factors in canine cryopoor plasma, cryoprecipitate, and fresh frozen plasma.

Objective: To compare albumin concentrations, coagulation factors activity, and colloid osmotic pressure (COP) of cryoprecipitate (CRYO) and cryopoor plasma (CPP) to that of source fresh frozen plasma (FFP).

Design: Prospective in vitro study.

Setting: University teaching hospital.

Effect of ascorbic acid on storage of Greyhound erythrocytes.

Objective: To assess changes in biochemical and biophysical properties of canine RBCs during cold (1° to 6°C) storage in a licensed RBC additive solution (the RBC preservation solution designated AS-1) supplemented with ascorbic acid.

Sample: Blood samples from 7 neutered male Greyhounds; all dogs had negative results when tested for dog erythrocyte antigen 1.1.

Plasma N-terminal pro-B-type natriuretic peptide concentration in healthy retired racing Greyhounds.

Background: N-terminal pro-B-type natriuretic peptide (NT-proBNP) is a cardiac biomarker whose plasma concentration is high in some dogs with cardiopulmonary disease. NT-proBNP is a diagnostic tool that can be used to help determine if a patient has congestive heart failure. Greyhounds have functional heart murmurs, relative cardiomegaly, and high serum cTnI concentration.

Evaluation of hemostatic activity of canine frozen plasma for transfusion by thromboelastography.

Background: In humans, fresh frozen plasma (FFP) loses factor V and VIII activities after 1 year. It then becomes frozen plasma (FP), and theoretically is unsuitable for use in patients with coagulopathies. These findings have not been reported for dogs.

Effect of sevoflurane anesthesia and blood donation on the sonographic appearance of the spleen in 60 healthy cats.

The aims of this prospective study were to describe the normal sonographic size and appearance of the feline spleen, and to test effects of sevoflurane anesthesia and blood collection on sonographic characteristics. Sonographic evaluations were performed in 60 healthy blood donor cats prior to anesthesia and blood collection (baseline), after anesthesia induction, after completion of blood collection while under anesthesia, and 7-10 days after blood collection. Transverse sonographic images of the splenic mid-body were made.

Epsilon aminocaproic acid for the prevention of delayed postoperative bleeding in retired racing greyhounds undergoing gonadectomy.

Objective: To evaluate the effects of epsilon aminocaproic acid (EACA) on the prevalence of postoperative bleeding in retired racing Greyhounds (RRG), and to assess its effects on selected thrombelastography (TEG) and fibrinolysis variables.

Study Design: Double-blinded, prospective, randomized study.

Methods: 100 RRG had elective ovariohysterectomy or orchiectomy and were administered EACA or placebo for 3 days after surgery.

Retrospective evaluation of the effectiveness of epsilon aminocaproic acid for the prevention of postamputation bleeding in retired racing Greyhounds with appendicular bone tumors: 46 cases (2003-2008).

Objectives: To determine the frequency of delayed postoperative bleeding in retired racing Greyhounds with appendicular bone tumors undergoing limb amputations. To identify if administration of epsilon-aminocaproic acid (EACA) was effective on the prevention of postoperative bleeding.

Design: Retrospective study from December 2003 to December 2008.

Seroprevalence of Ehrlichia canis, Ehrlichia chaffeensis and Ehrlichia ewingii in dogs in North America.

Background: This study evaluated the exposure of dogs to three different Ehrlichia spp. in the south and central regions of the United States where vector-borne disease prevalence has been previously difficult to ascertain, particularly beyond the metropolitan areas.

Methods: Dog blood samples (n = 8,662) were submitted from 14 veterinary colleges, 6 private veterinary practices and 4 diagnostic laboratories across this region.

Serum concentrations of IgG, IgA, and IgM in retired racing Greyhound dogs.

Background: Greyhound dogs have significant physiologic, hematologic, and biochemical differences when compared with other breeds, including significantly lower serum globulin concentration owing to decreases in the α- and β-globulin fractions. The specific proteins that account for differences in globulin concentrations are not known, but IgA and IgM, both β-globulins, are potential candidates.

Objectives: The aims of this study were to measure serum IgG, IgA, and IgM in clinically healthy retired racing Greyhounds and compare the results with those of age- and sex-matched non-Greyhound dogs.

Acute phase protein concentrations in retired racing Greyhounds.

Background: Retired racing Greyhounds are popular as pets. Greyhounds have several differences in physiological values compared with other breeds, including lower serum alpha- and beta-globulin concentrations. We hypothesized that lower acute phase protein (APP) concentrations could contribute to lower alpha- and beta-globulin concentrations in this breed.

Evaluation of a point-of-care hematology analyzer for use in dogs and cats receiving chemotherapeutic treatment.

Objective: To compare WBC, neutrophil, and platelet counts and Hct values obtained with a point-of-care hematology analyzer with values obtained by a reference method for dogs and cats receiving chemotherapy.

Design: Cross-sectional study.

Animals: 105 dogs and 25 cats undergoing chemotherapy.

Effects of blood collection for transfusion on arterial blood pressure, heart rate, and PCV in cats.

Background: Collection of 50 mL of blood (standard unit) in cats is a common procedure. There are several studies on the health status of donors, but to our knowledge there are no reports on the effects of blood collection on the feline donor.

Hypothesis: Collection of a standard unit of blood from cats does not significantly change arterial blood pressure (BP), mean arterial pressure (MAP), systolic arterial pressure (SAP), diastolic arterial pressure (DAP), PCV, and heart rate (HR) in healthy blood donor cats.

Comparison of glomerular filtration rate between greyhounds and non-Greyhound dogs.

Greyhounds have significantly higher serum creatinine (SCr) concentration than do non-Greyhound dogs that may be attributable to differences in glomerular filtration rate (GFR). By means of plasma clearance of technetium Tc 99m diethylenetriaminepentaacetic acid, GFR was measured in 10 Greyhounds and 10 non-Greyhound dogs with normal findings of physical examination, CBC, serum biochemical analysis, and urinalysis. Dogs were fed the same diet for a minimum of 6 weeks before GFR data collection.
