RESUMO
Lameness, mostly resulting from claw lesions, causes major welfare problems in the dairy industry. One way to prevent claw lesions is hoof trimming, but the overall effect and the optimal hoof trimming frequency are unknown. In a retrospective cohort study, we investigated the association between hoof trimming frequency in primiparous cows and hoof health and culling in second lactation. We based our analysis on breed, calving and culling data in the period 2015-2018 for 30,613 primiparous cows in 202 Swedish dairy herds. Of the cows enrolled, 20% were not hoof-trimmed, 30% were trimmed once, 34% were trimmed twice, 13% were trimmed 3 times, and 2% were trimmed ≥ 4 times. We used multivariable mixed-effect logistic and multivariable multinomial logistic regression models to investigate the association between trimming frequency and 2 outcomes: hoof lesions at first trimming occasion within 90 d from second calving and culling in second lactation within 300 d after second calving. In general, cows trimmed 2 or 3 times during first lactation were at lower odds of having claw lesions compared with cows that were not trimmed (Odds Ratio (OR) = 0.66, 95% CI = 0.62-0.71 and 0.60, 95% CI = 0.55-0.66, respectively) or cows trimmed once (OR = 0.80, 95% CI = 0.75-0.85 and OR = 0.72, 95% CI = 0.66-0.79, respectively), and this beneficial effect was observed for most types of claw lesions. Moreover, cows trimmed 2, 3, or ≥ 4 times were at lower odds of being culled compared with cows that were not trimmed (OR = 0.71, 95% CI = 0.65-0.77, 0.68, 95% CI = 0.61-0.76 and 0.70, 95% CI = 0.54-0.90, respectively) or trimmed once (OR = 0.77, 95% CI = 0.71-0.83, OR = 0.74, 95% CI = 0.66-0.82 and OR = 0.75, 95% CI = 0.59-0.97, respectively). In particular, 2 trimmings, compared with 1 or no trimming, lowered the relative risk-ratio of dying or being euthanized on-farm, or being culled due to claw and leg disorders. More than 1 hoof trimming in first lactation also reduced the relative-risk ratio of being culled for other reasons. In conclusion, 2 or 3 hoof trimmings during first lactation were generally beneficial for hoof health in early second lactation and survival in second lactation. These findings can help improve animal welfare and production by reducing claw lesions, and thereby lameness among dairy cows, which would increase the longevity of dairy cows and the sustainability of the dairy industry.
RESUMO
We report a rare case of a primary synovial sarcoma of the pericardium. Surgical resection was incomplete and chemotherapy and radiotherapy (tomotherapy) were therefore administered. Regular cardiac magnetic resonance imaging scans were used throughout the follow-up, allowing effective planning and application of adjuvant therapies. The survival of our patient was 26 months, substantially longer than most previously reported cases.

INTRODUCTION AND OBJECTIVES: To evaluate the lipid profile of patients admitted with acute coronary syndrome in Toledo (Spain) between 2005 and 2008. METHODS: Total cholesterol, LDL-cholesterol, HDL-cholesterol and triglyceride levels were evaluated. Descriptive analyses and means comparison were performed. RESULTS: 1,381 patients of 3,986 admitted with acute coronary syndrome had a complete lipid profile. The mean age was 67.8±12.9 years (72.4% men). A first event was present in 76.3%. The mean total cholesterol (±SD) was 180.0±43.4, LDL-cholesterol 115±38.0, HDL-cholesterol 44.1±12.3, and triglyceride 145.3±92.4mg/dL, with statistically significant differences between men and women in LDL-cholesterol (116.3±37.8 vs 111.6±38.5mg/dL; p=0.04) and HDL-cholesterol (42.3±11.6 vs 48.4±13.2mg/dL; p=0.0001). In first or recurrent events were found, respectively, total cholesterol 179.1±43.1 and 174.5±44.1 (p<0.05), LDL-cholesterol 116.5±38.4 and 110±36.5 (p=0.007), HDL-cholesterol 44.1±12.2 and 44.2±12.9 (p<0.05), and triglyceride 141.2±81.7 and 158.5±119.7 (p=0.03). Optimal levels of LDL-cholesterol and HDL-cholesterol were found in 14.1 and 11.6% of patients with recurrent episodes, respectively. CONCLUSIONS: While most patients admitted with first episode of acute coronary syndrome to the Toledo Health Area have a lipid profile according to current guidelines, only 10% of those with recurrent acute coronary syndrome presented optimal LDL-cholesterol and HDL-cholesterol levels, which suggest the need to be more aggressive in the lipids control.
