A new diet supplement formulation containing cranberry extract for the treatment of feline idiopathic cystitis

Effects of cranberry powder on the diversity of microbial communities and quality characteristics of fermented sausage

Fermented sausage is popular with many consumers because of its distinctive flavor, but the safety of it has attracted widespread attention. At present, nitrite is widely used in fermented meat products because of its ideal color and bacteriostatic effect, but nitrite can be transformed into nitrosamines, which cause strong carcinogenic effects. Therefore, it is urgent to actively explore safe and efficient nitrite substitutes. In this study, cranberry powder was selected as a natural substitute for nitrite during the production of fermented sausage due to its unique antioxidant and bacteriostatic properties. The results showed that adding an appropriate amount of cranberry powder (5 g/kg) promoted a better color of the fermented sausage and promoted the accumulation of aromatic compounds. Furthermore, Pediococcus and Staphylococcus became the dominant species, accounting for more than 90% in all samples. According to the Pearson correlation analysis, Staphylococcus and Pediococcus had positive effects on the quality characteristics of fermented sausage products. This study provided the latest information on the application of cranberry powder as a natural substitute for nitrite in the process of manufacturing fermented sausage, and it also introduced an advanced solution to improve the quality characteristics and safety of fermented sausage products during processing.

Prevalence, Risk Factors, Pathophysiology, Potential Biomarkers and Management of Feline Idiopathic Cystitis: An Update Review

Feline idiopathic cystitis is a widespread disease in small animal clinics, which mainly presents with urinary signs like dysuria, stranguria, hematuria, pollakiuria, and periuria. The etiopathogenesis of the disease may involve interactions between the environmental stressors, neuroendocrine system and bladder of affected cats. Diagnostic biomarkers have not been tested in clinical studies though they are theoretically feasible, and since the clinical signs of the disease assemble those of other feline lower urinary diseases, its diagnosis is a procedure of exclusion. The primary treatment of the disease is long-term multimodal environmental modification (or enrichment) while anti-anxiety drugs and nutritional supplements are recommended for chronic recurrent cases. Still, many medicines need to be evaluated for their efficacy and safety. This review aims to provide readers with a comprehensive understanding of feline idiopathic cystitis by summarizing and updating studies concerning the prevalence, risk factors, etiological hypotheses, diagnostic procedures, possible treatments, and prognosis of the disease.
