This study was conducted to evaluate the effects of dietary free fatty acid(FFA)content and degree of fat saturation on production performance,lipid and calcium digestibility,and intestinal function of laying *** a 15-week period,a total of 144 laying hens(19 weeks old)were randomly assigned to 8 dietary treatments,which were obtained by gradually replacing crude soybean oil with soybean acid oil(AO),or crude palm oil with palm fatty acid distillate(FAD).Thus,there were 4 soybean and 4 palm diets with 6%added fat varying in their FFA percentage(10%,20%,30%,and 45%),following a 2×4 factorial *** treatment included 6 replicates with 3 birds per *** daily feed intake and final body weight were significantly higher in palm diets(P<0.001),while no differences were found in egg mass and feed conversion *** levels of FFA in soybean diets resulted in lower egg production and higher egg weight(linear,P<0.01).Regarding the degree of fat saturation,hens fed soybean diets presented higher digestibility of ether extract(EE),fatty acids,and calcium than palm diets(P<0.001).The dietary FFA percentage negatively affected the digestibility of EE and calcium(P<0.01),while having little effect on FA *** was a significant interaction in the AME;lower values were reported in soybean diets as the dietary FFA percentage increased(linear,P<0.01),whereas palm diets remained *** experimental diets had little effect on gastrointestinal weight and ***,the jejunum of soybean diets showed higher villus height and higher villus height-to-crypt depth ratio than palm diets(P<0.05),and the dietary FFA percentage increased the crypt depth and decreased the villus height-to-crypt depth ratio(linear,P<0.05).It was concluded that varying dietary FFA content did not affect fat utilization as much as the degree of saturation did,supporting the use of AO and FAD as alternative fat ingredients.

After the first secondarily-transmitted ebola case in Spain, a wave of divergent opinions flooded mass and sanitary media. Very few of these opinions, however, came from experts on epidemiology or hemorrhagic fevers. This observational study aimed to assess the specific knowledge of Primary Care physicians and nurses about ebola and hemorrhagic fevers by means of analyzing the results obtained from a 5-item self-reported questionnaire dealing on hemorrhagic fevers basic knowledge. Validity and reliability of questionnaire were confirmed by a pilot study. The participants were 138 family doctors and nurses from the 64 public Primary Care centers sited in the North Metropolitan Area of Barcelona (1,400,000 inhab;Catalonia, Spain) taking part in training-the-trainers ebola workshops. Overall, there were 117 (84.8%) respondents out from 138 workshop participants;of them were physicians 61 (51.2%). The main age was 46.7 (8.8) years;stating previous specific knowledge on hemorrhagic fevers 39 (33.3%). On the whole, up to 92 (78.6%) of respondents shown a poor knowledge. Previous specific formation was significantly and independently associated with having proper knowledge (p < 0.001);OR = 8.6 (CI 95%: 3.199 - 23.623). In summary, confusion that accompanied the single secondary-transmitted ebola case in Spain could probably be explained by the existence of a serious gap on hemorrhagic fevers knowledge. More accurate, scientific and formally-presented information should be provided to Primary Care physicians and nurses.

Sea cucumbers are common foods in Asian culture. They are commonly eaten as dry-salted. Thus, a dry-salting protocol for cucumbers includes the processes of: gutting, cooking, salting, drying and packing. Drying trials were conducted at 50℃ and 60℃ in an oven and air-dried, with no difference (P > 0.05) in yield observed between them. Protein content varied depending on the type of drying, while fat content did not change significantly (P > 0.05). Final yield ranged between 5% to 7% of initial mass, with the main losses in mass (due to water loss) registered in the gutting and cooking stages. The sea cucumbers dried in an oven at 60℃ reached the humidity goal faster and there were statistically significant differences (P Isostichopus sp. aff badionotus is for consumers a viable alternative source of protein.

AIM:To evaluate the effectiveness of infliximab as a second-line therapy in Crohn's disease patients after adalimumab failure. METHODS:A historical cohort study in a community-based gastroenterology practice evaluated Crohn's disease patients treated with infliximab (induction plus maintenance) after adalimumab failure. Patients were identified using a large Spanish database (ENEIDA). RESULTS:We included 15 Crohn's disease patients who received infliximab after adalimumab failure. Five patients discontinued adalimumab due to loss of response, 3 due to adverse events and 7 due to partial response. After infliximab therapy was started, all patients who had interrupted adalimumab due to loss of efficacy regained response. All patients who discontinued adalimumab due to adverse events responded to infliximab and maintained this response; one of these patients had an uneventful course on infliximab, but 2 developed adverse events. None of the 7 patients who interrupted adalimumab due to partial response reached remission with infliximab. CONCLUSION:Switching from adalimumab to infliximab may be useful in patients who develop adverse effects or loss of response, however, the benefit of infliximab in primary nonresponders was not established.
