BACKGROUND:The impact of rapid on-site evaluation (ROSE) on thyroid aspirates has been a matter of extensive debate. In the current study, the authors reviewed all thyroid fine-needle aspiration biopsies (FNABs) performed in their service in recent years to evaluate the impact of ROSE on final adequacy and diagnostic rates. METHODS: All ultrasoundguided FNABs of the thyroid performed between July 2015 and July 2017 were included retrospectively. ROSE was performed by experienced cytopathologists, with production of Romanowsky-stained slides for immediate evaluation.When ROSE was not performed, a total of 3 needle passes were performed as the default. Final specimen adequacy and the risk of malignancy (ROM) of each The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) category were calculated in the 2 groups (ROSE and non-ROSE) and compared using the chi-square test. RESULTS: An initial search obtained 4649 cytology specimens, 3469 of which (74.6%) underwent ROSE and 1180 of which (25.4%) did not.Patients were predominantly female (85.4%), with a mean age of 53 years. Specimen adequacy was found to be significantly higher in the ROSE group (93.4% vs 69.4%; P<.0001), with a mean number of needle passes necessary for an adequate diagnosis of 1.48 ± 0.71 (median, 1.0 needle passes; range, 1-5 needle passes). No statistical difference was observed with regard to the ROM for each TBSRTC category when the 2 groups (ROSE and non-ROSE) were compared. CONCLUSIONS:The current study data support ROSE as a valuable technique in thyroid FNAB. It was proven to significantly improve specimen adequacy with a decreased mean number of needle passes necessary to achieve an adequate cytological diagnosis and no impact on the ROM for any TBSRTC category.

-This study was designed to investigate the effect of early weaning and concentrate supplementation on performance and metabolic profile of lambs in four production systems on pasture: suckling lambs not supplemented until slaughter; suckling lambs supplemented with concentrate in creep feeding until slaughter; early weaned lambs not supplemented until slaughter; early weaned lambs supplemented with concentrate until slaughter. Performance was assessed by average daily gain (ADG) and body condition score (BCS) measurements. Concentrate supplementation has similar response to suckling on the performance and metabolic profile of animals, and may be considered an efficient strategy to improve the nutritional status of early weaned lambs.

This study evaluated the cervical transposition method as a tool to select ewes for embryo collection by transcervical route. Adult Santa Inês ewes (n = 50) received Day 0 protocol for superovulation treatments. The cervix transposition test was performed both at oestrus and at the embryo collection time. The latter was preceded by hormonal cervical dilation. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy were 85.7%, 66.6%, 85.7%, 66.6% and 80.0%, respectively. The kappa index yielded a moderate score (κ = 0.52). In conclusion, the high sensitivity and accuracy indicate that the cervical transposition test is a screening option to select ewes for embryo collection by transcervical route.
