Effect of postpartum administration of ketoprofen on proinflammatory cytokine concentration and their correlation with lipogenesis and ketogenesis in Holstein dairy cows

Early lactation period in dairy cows could be harmful to their health since it is challenging and demanding. Proinflammatory cytokine concentrations are increased in the early phase of the inflammatory response and during the early lactation period in cows. The aim of this study was to determine if ketoprofen treatment in the first days following parturition would decrease proinflammatory cytokine concentration and their correlation between lipid mobilization, ketogenesis and metabolic parameters in cows. The study was conducted on 30 cows divided into two groups of 15 cows each. The experimental group was treated with 3 mg × kg.bw.-1 ketoprofen for three consecutive days after parturition. The blood samples were collected on the first day of treatment and in the first and second week postpartum and they were analyzed for biochemical parameters such as non-esterified fatty acids (NEFA), beta-hydroxybutyrate (BHBA), glucose, cholesterol and total bilirubine and inflammatory parameters such as tumour necrosis factor-α (TNF-α), interleukin-1α (IL-1α) and interferon-γ (IFN-γ). The results suggested that ketoprofen- treated cows had a significantly lower concentration of TNF-α, IL-1α, IFN-γ, NEFA and BHBA in the first and second postpartum week compared to the control group. Ketoprofen administration increased glucose levels (the first week, p⟨0.05), increased cholesterol levels (the second week, p⟨0.01) and decreased serum total bilirubin levels (second week, p⟨0.01) compared to the control group of cows. A positive correlation was found between TNF-α and NEFA and total bilirubin, significantly more expressed in the control than in experimental group of cows (p⟨0.01) and it was also found between IL-1α and NEFA (p⟨0.01). A negative correlation was found between TNF-α and glucose and cholesterol, significantly more expressed in the control than in experimental group of cows (p⟨0.01). A positive correlation was also found between IL-1α and glucose (p⟨0.01). Ketoprofen given parenterally to Holstein cows immediately after calving could reduce inflammation and decrease the relation between inflammatory response and lipogenesis and ketogenesis in postpartum cows.

Association of metabolic and inflammatory markers with milk yield in postpartum dairy cows treated with ketoprofen

Inflammation together with lipolysis and ketogenesis in early lactation can cause low productivity and may be harmful to the cow health. The objective of the study was to determine if ketoprofen treatment in the first days following parturition would positively affect the milk production and whether it was associated with the metabolic and inflammatory response. The study was conducted on 30 cows divided into two groups of 15 cows each. The experimental group was treated with 3 mg × kg. bw. -1 ketoprofen for three consecutive days after parturition. The blood samples were collected on the first day of treatment and in the first and second week postpartum and they were analyzed for non-esterified fatty acids (NEFA), beta-hydroxybutyrate (BHB), tumour necrosis factor-a(TNF-a) and haptoglobin. The results suggested that ketoprofen-treated cows with a higher milk production had a significantly lower concentration of NEFA, BHB, TNF-a and haptoglobin in the first and second week postpartum. No differences were found in the control group in metabolic status regardless of the achieved level of milk production. Ketoprofen administration in postpartum cows can enhance the milk yield. The higher milk yield in the experimental group might be associated with a lower degree of lipolysis, ketogenesis and reduced inflammatory response in the first two weeks postpartum.

Demographic characteristics of patients with laryngeal cancer and their socioeconomic status

PURPOSE

To define demographic characteristics of patients with laryngeal cancer in central Serbia, and to investigate possible relationships between their socioeconomical status and the appearance of laryngeal cancer.

METHODS

100 patients (cases) with histologically verified laryngeal cancer were investigated. The control group consisted of 100 patients (controls) having no cancer. A questionnaire was filled in by both cases and controls and comparison between the groups was carried out by individual matching of demographic characteristics and socioeconomical status.

RESULTS

91% of the cases and controls were male (mean age 60 years). Most of the cases had lower educational level and poorer socioeconomical status compared to controls, whilst no difference was found between the 2 groups concerning their living in urban or rural environment.

CONCLUSION

It was not possible to correlate urban environment (air pollution) as risk factor. People of lower educational level and poor socioeconomical status had increased risk of getting laryngeal cancer.
