Studies on active travel amongst CYP are limited, however, with most research focusing on adult participants or on adult perceptions of children.

Background: Knowledge of the clinical and magnetic resonance imaging (MRI) features of intracranial Coccidioides infection in dogs is essential for prompt diagnosis to limit disease-associated morbidity and death.

Objectives: To describe the MRI appearance of intracranial coccidioidomycosis in dogs, identify associated clinical and clinicopathologic findings, and report outcomes of medical treatment.

Animals: Forty-five client-owned dogs with presumed intracranial Coccidioides infection.

A Western Diet (WD) low in fiber but high in fats and sugars contributes to obesity and non-alcoholic fatty liver disease (NAFLD). Supplementation with grape polyphenols (GPs) rich in B-type proanthocyanidins (PACs) can attenuate symptoms of cardiometabolic disease and alter the gut microbiota and its metabolites. We hypothesized that GP-mediated metabolic improvements would correlate with altered microbial metabolites such as short chain fatty acids (SCFAs).

The neurological examination findings, clinical pathology (including Coccidioides immitis IgG/IgM serology) and magnetic resonance imaging (MRI) findings in 13 dogs with a novel form of intracranial coccidioidomycosis are described in a retrospective case series, with long-term clinical resolution documented in 11/13 dogs (84.6% of cases) with oral fluconazole therapy. The medical records of the Veterinary Neurological Center in Phoenix, Arizona from the years 2000 to 2017 were utilized to search for dogs with appropriate inclusion criteria.

Five young Shiloh Shepherd Dogs (4 males and 1 female) related by a common sire were studied because of progressive pelvic limb weakness and incoordination. All dogs had a spastic paraparesis and pelvic limb ataxia consistent with an upper motor neuron and general proprioceptive lesion between spinal cord segments T3 and L3. Proliferative lesions involving one or more of the articular processes from the 11th thoracic vertebrae to the 2nd lumbar vertebra were observed on radiographs of the thoracolumbar vertebrae.
