A retrospective description of blood and urine alterations in 386 male cats with urethral obstruction in Botucatu, São Paulo, Brazil.

Background: Urinary retention in obstructed male cats leads to changes in blood and urine compounds, which, combined with the time of obstruction, are linked to the worsening of the animal's clinical status.

Aim: This study aimed to describe the primary laboratory changes in male cats with urethral obstruction (UO).

Methods: Medical records of 386 male cats diagnosed with UO and treated at the Veterinary Teaching Hospital of the Faculty of Veterinary Medicine and Zootechnics (FMVZ), UNESP-Botucatu, between 2010 and 2020 were reviewed.

Serum concentrations of IL-1β, IL-6, and TNF-α in dogs with chronic kidney disease in uremic syndrome undergoing intermittent hemodialysis with and without bypass.

Intermittent hemodialysis (IH) is an important therapy in the context of kidney dysfunction in dogs. However, its impact on pro-inflammatory cytokines is unclear. This study assessed IL-1β, IL-6, and TNF-α serum concentrations in dogs with chronic kidney disease (CKD) undergoing one session of IH without bypass (IH group,  = 4) and with bypass (IH + bypass group,  = 4).

Arterial spin labelling could detect the occlusion of inferior petrosal sinus for cavernous sinus dural arteriovenous fistula.

Several reports indicate that arterial spin labelling (ASL) MRI is useful for the diagnosis, identification of cortical venous reflux, and assessment of therapeutic effect in dural arteriovenous fistula (dAVF). However, there is no reports indicating the utility of ASL in the identification of venous sinus obstruction. We herein report the case of a 72-year-old woman who presented with diplopia and right trigeminal neuralgia due to bilateral cavernous sinus dAVF.

Periovulatory anticoagulant therapy enhances embryo recovery rates in superovulated mares.

Although protocols for superovulation have been described in horses, this technique has been discouraged due to the low embryo recovery rates in superovulated mares. The reason for these poor results is poorly understood, but the formation of a blood clot in the ovulation fossa following ovulations has been hypothesized. Therefore, this study aimed to assess the safety and effect of periovulatory anticoagulant therapy on embryo recovery of superovulated mares.

Clinical and pathological findings of Africanized bee (Apis mellifera) envenomation in horses.

Africanized crossbred bees (Apis mellifera) originated in Brazil in 1957, and since then, the number of accidents involving humans and animals has significantly increased. Although they are considered clinical emergencies, there are few reports describing the clinical and pathological aspects of bee envenomation in horses. In this context, this report aims to describe the clinical and pathological features of bee toxicity after massive bee envenomation in three horses.

Brain Abscesses in Domestic Ruminants: Clinicopathological and Bacteriological Approaches.

Brain abscesses in ruminants often arise from primary infection foci, leading to an unfavorable prognosis for affected animals. This highlights the need for comprehensive studies on brain abscesses across different ruminant species. We retrospectively investigated medical records of epidemiological, clinical, neuroimaging, anatomopathological, and bacteriological findings in six ruminants (three goats, two cows, and one sheep) diagnosed with brain abscesses.

Evaluation of coagulation profile in dogs with ACTH-dependent hyperadrenocorticism compared to healthy dogs by rotational thromboelastometry (ROTEM).

Despite their low morbidity, thromboembolic events in hyperadrenocorticism are associated with high mortality. Identifying the main hemostatic abnormalities will improve the prophylactic approach of these canine patients. The aim of this study was to evaluate hemostatic alterations related with ACTH-dependent HAC and its association with hypercoagulable state.

Do neutrophil extracellular traps implicate in atheromatous plaques from carotid endarterectomy? Re-analyzes of cDNA microarray data by surgeons.

Background: Carotid artery stenosis is the cause of 15% of strokes. Neutrophil extracellular traps (NETs) and peptidyl arginine deiminase 4 (PAD4) are believed to be involved in thrombosis. This pilot study described the differential expression profile of NETs between atheromatous plaques and surrounding tissues.

Novel renal injury markers in dogs with ehrlichiosis.

Canine monocytic ehrlichiosis (CME) has been observed to impact renal function. Currently, the recognition of acute kidney injury is through the nonspecific biomarker serum creatinine (sCr). Novel markers of renal injury such as urinary clusterin (uClust) and urinary cystatin B (uCysB) may increase our understanding of the relationship between ehrlichiosis and renal cellular injury.

Pleural effusion-related Nocardia otitidiscaviarum, Anaplasma platys and Ehrlichia canis coinfection in a dog.

The coinfections by some microorganisms have been related to severe diseases in humans and animals, where immunosuppressive agents favor opportunistic behavior of other pathogens. A 4-month-old, female mixed-breed dog with a two-week history of inappetence, prostration, emaciation, and respiratory distress was admitted at a veterinary hospital in Brazil. Tachycardia, pale mucous membranes, severe respiratory distress, and a large number of ticks (Rhipicephalus sanguineus s.

Effects of dietary copper and zinc hydroxychloride supplementation on bone development, skin quality and hematological parameters of broilers chickens.

This study was carried out to evaluate the effects of supplementation with different levels of copper (Cu) and zinc (Zn), using two mineral sources (sulphate and hydroxy forms), on the bone characteristics, skin strength/elasticity, and haematological parameters of broilers. A total of 1792 1-day-old male Cobb-500 broiler chickens were randomly distributed among eight dietary treatments, using Cu sulphate (CSM) or hydroxychloride (CHC), and Zn sulphate (ZSM) or hydroxychloride (ZHC). The dietary treatments were as follows: (1) low-CSM/high-ZSM, (2) high-CSM/high-ZSM, (3) low-CHC/low-ZHC, (4) low-CHC/medium-ZHC, (5) low-CHC/high-ZHC, (6) high-CHC/low-ZHC, (7) high-CHC/medium-ZHC, and (8) high-CHC/high-ZHC.

Effect of acupuncture on hematologic, muscular biomarkers, fibrinogen and serum lactate parameters in training rodeo bulls.

The study aimed to evaluated the effects of acupuncture in rodeo bulls in training, by determining hematological variables, creatine kinase (CK), aspartate aminotransferase (AST), fibrinogen, and plasma lactate. Thirty adult healthy bulls, crossbred, were included in the study and randomly allocated into two groups of 15 animals, according to the use of acupuncture treatment for six months (GA) or not (GB). The variables were measured 30 min before (TP) and 10 min (TP), 12 (TP), 24 (TP), 48 (TP), and 72 h (TP) after a single episode of jumping emulating rodeo exercise.

Myeloperoxidase enzyme and Ferric-reducing antioxidant power concentrations in lean and obese dogs.

The study aimed to assess plasma Myeloperoxidase enzyme (MPO) and Ferric-reducing antioxidant power (FRAP) in obese dogs and compare them with ideal body weight dogs. Thirty-two dogs were distributed into two groups according to a 9-point body condition score (BCS), as follows: Control group (n = 16), dogs with a BCS of 4 or 5; Obese group (n = 16), dogs with a BCS of 8 or 9. Plasma MPO and FRAP assays, neutrophil count, lipid profile (cholesterol and triglycerides), and systolic blood pressure (SBP) were evaluated in both groups.

The red-handed howler monkey (Alouatta belzebul) is one of the 35 threatened Brazilian primate species found in two highly endangered Brazilian biomes. Their Amazonian native populations have been declining due to exponential deforestation associated with human activities, especially the construction of dams. The studied population (n = 27) was located in the Belo Monte dam Area of Influence.

Methods: We obtained serum samples from 26 monkeys, in which we analyzed 20 biochemical variables.

Sequential Cerebrospinal Fluid Sampling in Horses: Comparison of Sampling Times and Two Different Collection Sites.

Analysis of the cerebrospinal fluid (CSF) is important as a complementary test in horses with neurologic diseases, and sequential analysis may provide information about the treatment response or evolution and quantitative measures of the CSF drug concentration during treatment. The aim of this study was to compare erythrocyte and nucleated cell counts and protein concentration in multiple CSF samples obtained sequentially from two different puncture sites in clinically healthy horses. Eight and 12 horses, with no evidence of neurologic disease, were subjected to CSF collection from the atlanto-occipital (AO) and C1-C2 spaces, respectively.
