Chronic feeding of a high fat diet (HFD) in preclinical species induces broad metabolic dysfunction characterized by body weight gain, hyperinsulinemia, dyslipidemia and impaired insulin sensitivity. The plasma lipidome is not well characterized in dogs with HFD-induced metabolic dysfunction. We therefore aimed to describe the alterations that occur in the plasma lipid composition of dogs that are fed a HFD and examine the association of these changes with the clinical signs of metabolic dysfunction.

Article Synopsis
  • The study aimed to analyze the effects of a high-fat diet on body composition, insulin sensitivity, blood lipids, and metabolic changes in aging.
  • 24 male Beagle dogs were divided into two groups, one continuing their regular diet and the other switched to a high-fat diet for 17 weeks.
  • Results indicated that the high-fat diet led to weight gain, increased fat mass, insulin resistance, and higher serum lipid levels, mirroring metabolic dysfunction associated with aging.

Advances in professional recognition of nursing informatics vary by country but examples exist of training programs moving from curriculum-based education to competency based frameworks to produce highly skilled nursing informaticians. This panel will discuss a significant credentialing project in the United States that should further enhance professional recognition of highly skilled nurses matriculating from NI programs as well as nurses functioning in positions where informatics-induced transformation is occurring. The panel will discuss the professionalization of health informatics by describing core content, training requirements, education needs, and administrative framework applicable for the creation of an Advanced Health Informatics Certification (AHIC).

Article Synopsis
  • The study focuses on pruritus (itchiness) in dogs, particularly those with atopic dermatitis, examining the role of IL-31, a cytokine linked to itchy behaviors.
  • Researchers compared the effects of three treatments—prednisolone, dexamethasone, and oclacitinib—on IL-31-induced pruritus in beagle dogs through randomized, blinded trials.
  • Results showed that oclacitinib was more effective in reducing pruritus at various intervals than both prednisolone and dexamethasone, suggesting a promising model for studying treatments for allergic dermatitis in dogs.

Drug discovery is an iterative process with high risks and low chance of success. New genomics technologies allow veterinary medicine and agrochemical companies to validate and functionally screen new receptor-based targets, including neuropeptide G-protein coupled receptors, which were previously not amenable to high throughput screening. However this is just the first step in a long process to translate a mechanistic assay hit into a drug on the market.

Insecticide resistance is a major problem for both medicine and agriculture and is frequently associated with overexpression of metabolic enzymes that catalyze the breakdown of pesticides, leading to broad-spectrum resistance. However, the insect tissues within which these metabolic enzymes normally reside remain unclear. Microarray analysis of nine adult tissues from Drosophila melanogaster reveals that cytochrome P-450s and glutathione-S-transferases show highly tissue-specific expression patterns; most were confined to one or more epithelial tissues, and half showed dominant expression in a single tissue.
