osed and separate and test or vaccinate and test. Farmers who had a lot of trust in other farmers and invested in them, rather than keeping everything for themselves, were more likely to be careful introducing new stock and test. In conclusion, farmer psychosocial factors were associated with strategies for BVD control in UK cattle farmers. Psychological proximity to veterinarians was a novel factor associated with proactive BVD control and was more important than the more extensively investigated trust. These findings highlight the importance of a close veterinarian-farmer relationship and are important for promoting effective BVD control by farmers, which has implications for successful nationwide BVD control and eradication schemes.Reduction of milk yield is one of the principal components in the cost of mastitis. However, past research into the association between milk yield and mastitis indicators is limited. Past research has not been based on online or in-line daily measurements and has not fully explored nonlinearity and the thresholds at which milk yield starts to decrease. In dairy herds with automated milking systems equipped with sensors, mastitis indicators of individual cows are measured on an intraday frequency, which provides unprecedented avenues to explore such effects in detail. The aim of this observational study was primarily to investigate the nonlinear associations of lactate dehydrogenase (LDH), electrical conductivity (EC), and somatic cell count (SCC) with milk yield at various stages of lactation, parity, and mastitis chronicity status (i.e., whether the cow had SCC ≥200,000 SCC/mL for the last 28 d). We also investigated thresholds at which mastitis indicators (LDH, EC, and SCC) started to be negatively associatds of 5.625 LnSCC (277,000 SCC/mL) and 3 LnLDH (20 LDH U/L) but not for EC. Having chronic mastitis decreased milk synthesis rate in all models. The identified nonlinearities between mastitis indicators and milk synthesis rate should be incorporated in statistical models for more accurate estimations of milk loss due to mastitis.Numerous empirical and mechanistic models predicting methane (CH4) production are available. The aim of this work was to evaluate the Molly cow model and the Nordic cow model Karoline in predicting CH4 production in cattle using a data set consisting of 267 treatment means from 55 respiration chamber studies. The dietary and animal characteristics used for the model evaluation represent the range of diets fed to dairy and growing cattle. Feedlot diets and diets containing additives mitigating CH4 production were not included in the data set. The relationships between observed and predicted CH4 (pCH4) were assessed by regression analysis using fixed and mixed model analysis. Residual analysis was conducted to evaluate which dietary factors were related to prediction errors. The fixed model analysis showed that the Molly predictions were related to the observed data (± standard error) as CH4 (g/d) = 0.94 (±0.022) × pCH4 (g/d) + 31 (±6.9) [root mean squared prediction error (RMSPE) = 45.0 g/d (14.9% of observed ibuted to the prediction error of CH4 yield with the Molly model. It was concluded that both models could be used for prediction of CH4 production in cattle, but Karoline was more accurate and precise based on smaller RMSPE, mean bias, and slope bias, and greater CCC. The importance of accurate input data of key variables affecting diet digestibility is emphasized.We evaluated the effects of abomasal infusion of emulsifiers on fatty acid (FA) digestibility and milk production of lactating dairy cows. All emulsifiers examined were polysorbates, nonionic surfactants, consisting of a polyethoxylated sorbitan esterified with FA. The polysorbates tested in this study consisted of the same polyethoxylated sorbitan base but differed by the FA esterified to it. Eight rumen-cannulated multiparous cows (89 ± 13 d in milk) were assigned to a treatment sequence in 4 × 4 Latin squares with 18-d periods consisting of 7 d of washout and 11 d of infusion. Treatments were abomasal infusions of water only (CON) or 30 g/d of different emulsifiers as follows polysorbate-C160 (T40), polysorbate-C180+C160 (T60), and polysorbate-C181 (T80). Emulsifiers were dissolved in water and delivered at 6-h intervals (total daily infusion was divided into 4 equal infusions per day). VX-561 Cows were fed the same diet that contained (% diet dry matter) 32.1% neutral detergent fiber, 15.7% crude protein, 25.8% bsorption of total, 16-, and 18-carbon FA. The T40 treatment tended to increase and T80 increased total FA absorption and the yields of milk fat and 3.5% FCM compared with CON. Milk fat yield was increased by increases in de novo, mixed, and preformed milk FA. In our short-term infusion study, results suggest that the predominant FA present in the polysorbate affects its ability to improve FA digestibility. Overall, FA digestibility and absorption were improved the most when cows received the T80 treatment.

Extra-articular malunions of metacarpals and phalanges may cause palmar pain, finger scissoring, and splaying, and interfere with function. Current treatment involves open osteotomy and fixation with plates and screws. We present a minimally invasive method using cannulated headless screws for correction of malunions and examine the outcomes in a series of patients.

Twenty malunions were operated on in 17 patients. In 16 cases, the malunion involved the metacarpal and in 4 it involved the proximal phalanx. All proximal phalanx and 3 metacarpal malunions were malrotation types, while the rest of the metacarpal malunions were dorsal angulations. The operation consisted of an opening wedge osteotomy in 8 patients; closing wedge osteotomy in 5; and a transverse osteotomy and derotation in the rest. Concomitant surgery to release tendon adhesions or contracted joints or to perform adipofascial flaps was performed in 8 cases. Fixation was achieved by means of a cannulated headless screw. Immediate range of motion was permitted in all cases.

Correction of the malunion and osteotomy union was achieved in all cases. One patient required manipulation of a digit that was found rotated at the first follow-up visit. Eleven fingers achieved more than 280° of total active motion. In 9 digits, the total active motion was less than 280° after the operation, yet improved 76° (range, 140°-30°) from their preoperative total active motion. The mean single-assessment numeric evaluation score for the whole group was 9.1.

The fixation provided by the cannulated headless screw is sufficient to permit immediate range of motion. Due to the minimal tissue disruption, this approach may be a reasonable alternative to the standard approach.

Chronic rhinosinusitis with nasal polyps (CRSwNP) is associated with asthma, particularly of late onset. Current treatment options for CRSwNP have limitations, and there is an unmet need for other safe and effective therapies.

The aim of the THUNDER study was to determine the efficacy and safety of the prostaglandin D

receptor 2 (DP

) antagonist fevipiprant in patients with CRSwNP and concomitant asthma, measured by improvement in nasal polyp score (primary end point), nasal congestion score, Sinonasal Outcome Test 22 score, and University of Pennsylvania Smell Identification Test score.

THUNDER was a phase 3b, randomized, multicenter, double-blind, placebo-controlled, parallel-group, 16-week study of fevipiprant 150 mg or 450 mg once daily versus placebo. All patients received intranasal mometasone furoate 200 μg daily.

Ninety-eight patients were randomly assigned to fevipiprant 150 mg (n= 32), fevipiprant 450 mg (n= 34), or placebo (n= 32). Mean (SE) change from baseline in nasal polyp score at week 16 was 0.20 (0.224) for fevipiprant 150 mg, -0.10 (0.216) for fevipiprant 450 mg, and 0.14 (0.233) for placebo. Mean treatment difference was 0.05 (95% confidence interval, -0.59, 0.70; adjusted P= .979) for fevipiprant 150 mg versus placebo and -0.25 (95% confidence interval, -0.88, 0.39; adjusted P= .656) for fevipiprant 450 mg versus placebo. There was no meaningful difference in the secondary end points for fevipiprant versus placebo.

THUNDER provided no evidence of a role for fevipiprant in the treatment of patients with CRSwNP and asthma; future studies may establish a role for other DP

antagonists, specifically in patients with aspirin-exacerbatedrespiratory disease.

The resulting material properties of the initial bioinks and final printing products usually lie within a moderate range, which limits the application of bioprinting and its products. Recent progress in bioinks and bioprinting techniques has significantly expanded the window of material properties. In this review, I define two bioprinting windows to clarify the trade-offs between physical chemistry and biology and provide a comprehensive overview of recent advances that have pushed the rheological boundaries of bioinks and mechanical boundaries of bioprints, focusing on unusual material properties. I illustrate this with recent examples, consolidate the existing strategies into well-defined categories, highlight the prominent trends, and provide perspectives on additional boundaries.Blood transfusion is the key to life in case of traumatic emergencies, surgeries and in several pathological conditions. An important goal of whole blood or red blood cell transfusion is the fast delivery of oxygen to vital organs and restoration of circulation volume. Whole blood or red blood cell transfusion has several limitations. Free haemoglobin not only loses its tetrameric configuration and extracts via the kidney leading to nephrotoxicity but also scavenges nitric oxide (NO), leading to vasoconstriction and hypertension. PFC based formulations transport oxygen in vivo, the contribution in terms of clinical outcome is challenging. The oxygen-carrying capacity is not the only criterion for the successful development of haemoglobin-based oxygen carriers (HBOCs). This review is a bird's eye view on the present state of the PFCs and HBOCs in which we analyzed the current modifications made or which are underway in development, their promises, and hurdles in clinical implementation.

Pleomorphic adenoma accounts for the majority of benign tumors of the salivary gland. It is also called mixed tumor because it is composed by ductal epithelial and myoepithelial cells, variably intermixed within a chondromyxoid stroma. The recurrence rate is around 3.4% and 6.3%, respectively at 5 and 10 years and, to date, there are no valuable predictive factors. Aim of our study was to assess the role of Ki67 proliferative index in our cases and through meta-analysis.

Immunohistochemistry with Ki67 antibody was performed on 28 cases. A manual count of the signal was performed, to establish the proliferative activity. Statistical tests were applied to assess the correlation between the score and clinico-pathologic parameters. Further data were extrapolated from studies published on Pubmed, Cochrane and Web of Science database.

Higher values of Ki67 were found among cases with larger size (p value = 0.0061) and showing greater cellularity (p value=0.0004). 19 papers were selected from the bibliographic search, concerning a total of 1187 patients affected by pleomorphic adenoma.
