The aim of the present studywas to assess the effects of introducing thismarine plant as a substitute for barley strawin the feed of mature ewes, assessing the effects of its addition on intake, digestibility and ruminal fermentation and on the ewes’ metabolic profiles (energy and protein). POwas used at 75 g day−1 per ewe (15% of the total forage), 150 g day−1 per ewe (30% of the total forage) and 300 g day−1 per ewe (60% of the total forage).
RESULTS: Substitution of 15% of the forage with PO has no negative consequences on dry matter intake, final live weight and metabolic status in mature ewes; in addition, POmay improve the animal’s nitrogen utilisation. The upper limit of substitution was 30%,where only fewchangeswere noted withoutmetabolic consequences. Substitution of 60% impaired performance and affects tissue functions in the animal’s body.
CONCLUSION: Moderate quantities of barley straw (between 75 and 150 g day−1 per ewe) can be replaced by PO in feed rations formature ewes
Suckling lamb meat quality from ewes fed with different sources of fat, during storage under display conditions
Producción CientíficaWe studied the effect of calcium soaps offered to ewes during lactation (CO, 3% Ca soap of palm oil; OLI, 3% Ca soap of olive oil; FO, 3% Ca soap of fish oil) on the microbial, physical-chemical and sensory properties of suckling lamb meat packaged with modified atmosphere packaging (80%O2:20%CO2) throughout storage; six ewes were tested per treatment. Microbial counts (Enterobacteriae, Pseudomonas spp., psychrotrophic and lactic acid bacteria), lipid oxidation (TBARS), colour coordinates (L*, a*, b*), metmyoglobin content and sensory quality were analysed on days 0, 5, 8 and 13 of storage. Throughout storage, the evolution of most parameters throughout depended on the lambs’ mothers' diet. From day 5 onward, microbial counts, as well as pigments and lipid oxidation, presented the highest values with FO. CO and OLI were rejected for poor sensory quality after 13 days, whereas FO reached the limit of rejection after 5 days. Therefore, the positive effect of increasing PUFA in sucking lamb meat via FO is limited due to a shorter shelf life.This research was subsidised by the Consejería de Educación de la Junta de Castilla y León and Instituto Tecnológico Agrario de Castilla y Leó

Grape pomace in ewes diet: effects on meat quality and the fatty acid profile of their suckling lambs
Producción CientíficaGrape pomace (GP) is an inexpensive natural antioxidant promising as animal feed supplement due to its high
content of phenolic compounds. In order to evaluate its effect in lactating ewe rations on meat quality and fat
composition of their suckling lambs, 48 Churra ewes were divided into 4 treatments. All animals were fed a
ration containing linseed oil (Control) supplemented with Vitamin E or two levels of GP. Lambs were nourished
exclusively by suckling until they were slaughtered. Dietary GP did not generate adverse effects on carcasses or
lambs meat quality when compared with Control or Vit-E diets. GP improved the water holding capacity of the
meat. In addition, lambs meat FA profile was not nutritionally affected with the diets assayed. Hence, the use of
GP as a dietary supplement in ewe rations would not have negative effects on meat from suckling lambs.INIA (RTA2010-0068-C02)Consejería de Educación de la Junta de Castilla y León (VA196A11-2
Molecular Relationships among Obesity, Inflammation and Intervertebral Disc Degeneration: Are Adipokines the Common Link?
Intervertebral disc degeneration (IVDD) is a chronic, expensive, and high-incidence musculoskeletal disorder largely responsible for back/neck and radicular-related pain. It is characterized by progressive degenerative damage of intervertebral tissues along with metabolic alterations of all other vertebral tissues. Despite the high socio-economic impact of IVDD, little is known about its etiology and pathogenesis, and currently, no cure or specific treatments are available. Recent evidence indicates that besides abnormal and excessive mechanical loading, inflammation may be a crucial player in IVDD. Furthermore, obese adipose tissue is characterized by a persistent and low-grade production of systemic pro-inflammatory factors. In this context, chronic low-grade inflammation associated with obesity has been hypothesized as an important contributor to IVDD through different, but still unknown, mechanisms. Adipokines, such as leptin, produced prevalently by white adipose tissues, but also by other cells of mesenchymal origin, particularly cartilage and bone, are cytokine-like hormones involved in important physiologic and pathophysiological processes. Although initially restricted to metabolic functions, adipokines are now viewed as key players of the innate and adaptative immune system and active modulators of the acute and chronic inflammatory response. The goal of this review is to summarize the most recent findings regarding the interrelationships among inflammation, obesity and the pathogenic mechanisms involved in the IVDD, with particular emphasis on the contribution of adipokines and their potential as future therapeutic targets
Dickkopf-3 (DKK3) Signaling in IL-1a-Challenged Chondrocytes: Involvement of the NF-?B Pathway
Objective: Osteoarthritis (OA) is an age-related biomechanical and low-grade inflammometabolic disease of the joints and one of the costliest and disabling forms of arthritis. Studies on matrix-degrading enzymes such as metalloproteases, which are implicated in the increased catabolism of extracellular matrix, are of paramount relevance. DKK3 is a member of DKK family and is best known for its role in cancer. Although there is some information about the participation of DKK3 in cartilage pathophysiology and on metalloproteases regulation, in particular, little is known about DKK3 signaling mechanisms. Thus, the aim of this study is to explore how DKK3 regulates matrix metalloproteinase-13 (MMP-13) expression.
Design: Gene, protein expression and protein phosphorylation in primary human chondrocytes and ATDC5 mouse cells were assessed by RT-qPCR and Western blot analysis. Further studies on DKK3 activity were performed by targeting DKK3 gene with a specific siRNA.
Results: DKK3 expression was found to be higher in OA human chondrocytes than healthy cells, being its expression decreased in interleukin-1? (IL-1?)-stimulated cells. DKK3 knockdown increased the induction of MMP-13 elicited by IL-1? in human and mouse chondrocytes and after the analysis of different signalling pathways, we observed that NF-?B pathway was involved in the regulation of MMP-13 expression by DKK3.
Conclusions: Herein we have demonstrated, for the first time, that DKK3 gene silencing exacerbated NF-?B activation, resulting in an increased IL-1?-driven induction of MMP-13. Our results further confirm that DKK3 may play a protective role in OA by attenuating NF-?B activation and the subsequent production of metalloproteases.Funding: OG and FL are Staff Personnel of Xunta de Galicia (Servizo Galego de Saude, SERGAS) through a research-staff stabilization contract (ISCIII/SERGAS).

Recommendations for the Treatment of Anti-Melanoma Differentiation-Associated Gene 5-positive Dermatomyositis-Associated Rapidly Progressive Interstitial Lung Disease
Objectives: The study aimed to develop evidence-based recommendations for the treatment of rapidly progressive interstitial lung disease (RPILD) associated with the anti-Melanoma Differentiation-Associated Gene 5-positive dermatomyositis (DM) syndrome.
Methods: The task force comprised an expert panel of specialists in rheumatology, intensive care medicine, pulmonology, immunology, and internal medicine. The study was carried out in two phases: identifying key areas in the management of DM-RPILD syndrome and developing a set of recommendations based on a review of the available scientific evidence. Four specific questions focused on different treatment options were identified. Relevant publications in English, Spanish or French up to April 2018 were searched systematically for each topic using PubMed (MEDLINE), EMBASE, and Cochrane Library (Wiley Online). The experts used evidence obtained from these studies to develop recommendations.
Results: A total of 134 studies met eligibility criteria and formed the evidentiary basis for the recommendations regarding immunosuppressive therapy and complementary treatments. Overall, there was general agreement on the initial use of combined immunosuppressive therapy. Combination of high-dose glucocorticoids and calcineurin antagonists with or without cyclophosphamide is the first choice. In the case of calcineurin antagonist contraindication or treatment failure, switching or adding other immunosuppressants may be individualized. Plasmapheresis, polymyxin B hemoperfusion and/or intravenous immunoglobulins may be used as rescue options. ECMO should be considered in life-threatening situations while waiting for a clinical response or as a bridge to lung transplant.
Conclusions: Thirteen recommendations regarding the treatment of the anti-MDA5 positive DM-RPILD were developed using research-based evidence and expert opinion.This project was supported by Spanish Rheumatology Society and Spanish Society of Internal Medicine (GEAS, Study Group on Autoimmune Diseases)

Association of Trabecular Bone Score with Inflammation and Adiposity in Patients with Psoriasis: Effect of Adalimumab Therapy
Studies on trabecular bone score (TBS) in psoriasis are lacking. We aim to assess the association between TBS and inflammation, metabolic syndrome features, and serum adipokines in 29 nondiabetic patients with psoriasis without arthritis, before and after 6-month adalimumab therapy. For that purpose, adjusted partial correlations and stepwise multivariable linear regression analysis were performed. No correlation was found between TBS and disease severity. TBS was negatively associated with weight, BMI, waist perimeter, fat percentage, and systolic and diastolic blood pressure before and after adalimumab. After 6months of therapy, a negative correlation between TBS and insulin resistance (?? = 0.02) and leptin (?? = 0.01) and a positive correlationwith adiponectin were found (?? = 0.01).The best set of predictors for TBS values at baseline were female sex (?? = 0.015), age (?? = 0.05), and BMI (?? = 0.001). The best set of predictors for TBS following 6 months of biologic therapy were age (?? = 0.001), BMI (?? < 0.0001), and serumadiponectin levels (?? = 0.027). In conclusion, in nondiabetic patients withmoderate-to-severe psoriasis, TBS correlates with metabolic syndrome features and inflammation.This association is still present after 6 months of adalimumab therapy. Moreover, serum adiponectin levels seem to be an independent variable related to TBS values, after adalimumab therapy
