Strategies of signalization of pork quality to final consumer

A suinocultura destaca-se na economia brasileira. Contudo, avaliando-se o consumo interno da carne suína in natura, observa-se uma estagnação em patamares baixos. O artigo tem como objetivo analisar as principais iniciativas adotadas pelo Sistema Agroindustrial (SAG) da carne suína no Brasil visando sinalizar qualidade aos consumidores. Devido à marcante assimetria de informações, ressalta-se a importância da organização da cadeia produtiva, melhor direcionando esforços para a expansão do mercado interno. Este trabalho sugere ações visando aprimorar a coordenação deste SAG com vistas à melhoria na qualidade da carne ao consumidor e à redução da informalidade.Swine production plays an important role in Brazilian economy. Nevertheless, internal pork meat consumption shows a tendency to maintain low levels. The present article analyses the key initiatives of the Pork Agro-Industrial Chain in signaling quality to the consumers. The presence of significant information asymmetry highlights the importance of organizing the productive chain through a vertical association, better guiding the efforts towards internal market expansion. This paper suggests different actions aiming a better coordination of this productive chain to assure higher levels of meat quality to consumer and the reduction of informality

Effects of mannan oligosaccharides on gilts and litters performance

O presente estudo buscou avaliar os efeitos dos Mananoligossacarídeos (MOS) como aditivo alimentar no desempenho de primíparas suínas em final de gestação e em lactação, bem como no desempenho e na saúde dos leitões até os 65 dias de idade. O experimento foi realizado no Laboratório de Pesquisa em Suínos (VNP-FMVZ-USP) Pirassununga SP. O delineamento experimental foi inteiramente casualizado em arranjo fatorial de tratamentos, sendo um fator o fornecimento dos MOS para fêmeas e o segundo para os leitões. Foram utilizadas 17 primíparas prenhes, tratadas a partir de 81 &plusmn;1,36 dias de gestação com 0,2% de MOS na dieta. Aos 82 &plusmn; 1,36 dias de gestação as fêmeas foram submetidas à coleta de sangue e à vacinação contra rinite atrófica progressiva, sendo pesadas quinzenalmente até a transferência para a maternidade, aos 109 &plusmn; 1,36 dias de gestação. Na segunda quinzena as fêmeas tratadas apresentaram uma vantagem numérica no ganho de peso médio diário (P=0,063). Durante o parto foram colhidas amostras de sangue e colostro para titulação de anticorpos contra o antígeno vacinal, sendo consideradas positivas 66,67% das fêmeas MOS e 42,86% das fêmeas controle. Os leitões aleitados por fêmeas tratadas tiveram um maior ganho numérico de peso na primeira semana (p=0,0614), significativo na segunda semana (p=0,047). Na terceira semana foi introduzido o segundo fator através do oferecimento de alimento sólido (0,4% de MOS). No período total, do nascimento aos 21 dias, foi observada uma vantagem numérica (p=0,0989) no ganho de peso a favor dos leitões de fêmeas MOS. As fêmeas, contudo, não diferiram quanto à variação de peso ou consumo durante a fase de lactação. Aos 23 &plusmn; 1,91 dias de idade dos leitões foi realizado o desmame abrupto com a transferência dos leitões para unidade de creche, onde foram alojados em gaiolas para 4 animais. O peso ao desmame foi maior nos leitões aleitados por fêmeas tratadas (p<0,0001), bem como em todas as pesagens semanais até a quinta semana pós-desmame. O consumo na primeira semana sofreu influência da suplementação de MOS nas fêmeas e do maior peso à desmama se mostrando superior nesses animais (P=0,049) influenciando diretamente o ganho de peso, superior na segunda semana (p=0,002). O MOS para os leitões aumentou o consumo de alimento (p=0,0784), e a conversão alimentar na segunda semana (p=0,0103). Aos 14 dias pós-desmame foram colhidas amostras de sangue para hemograma e realizada a aplicação oral de 108 UFC de Salmonella Typhimurium. Foram observadas diariamente a consistência das fezes por 28 dias e aferidas as temperaturas retais por 9 dias. Leitões tratados com MOS e os leitões oriundos de fêmeas MOS tenderam a apresentar o pico de hipertermia mais cedo que os demais (p=0,0629 e p=0,0976, respectivamente) e os leitões alimentados com MOS tenderam a ter uma temperatura de pico mais baixa (p=0,0989). Na última semana os leitões de fêmeas MOS apresentaram um maior consumo (p=0,0007) e uma incidência de Salmonella numéricamente inferior em linfonodos mesentéricos e nas fezes colhidas aos 36 dias pós-desafio. Pode-se concluir que a suplementação de MOS para primíparas prenhes e lactentes pode melhorar o desempenho e a saúde entérica de seus leitões nas fases de aleitamento e creche.The present study evaluated the effects of mananoligossacarides (MOS) as a feed additive on the performance of primiparous sows in late gestation and lactation, as well as on performance and health status of their progeny up to 65 days of age. The experiment was conducted in the Laboratory of Swine Research (FMVZ/USP) Pirassununga SP. For this purpose a completely random factorial design was used, factors which corresponded to (1) feeding sows with MOS and (2) feeding piglets with MOS, characterizing 4 treatments: MM Feeding MOS to both sows and piglets, MC Feeding MOS only to the sows, CM Feeding MOS only to piglets, CC Control diets for both sows and piglets. A total of seventeen pregnant gilts were used, and divided into 2 groups: MOS (n=9) and Control (n=8). MOS gilts had 0,1% MOS added to their diets from 81 &plusmn; 1,36 days of gestation onward. On day 82 &plusmn; 1,36 blood was collected and vaccination against Progressive Atrophic Rhinitis was conducted. Animals were weighted biweekly until 109 &plusmn; 1,36 days of gestation, when transference to the farrowing unit was conducted. Between the first and second weighing, MOS gilts show a numerical advantage in daily weight gain (p=0,063). At farrowing, blood and colostrum samples were collected for determination antibodies titles against vaccine antigen, being considered positive 66,67% and 42,86% of MOS and Control sows, respectively. Piglets nursed by MOS sows had a numerical advantage in weight gain in the first week (p=0,0614), with statistical significance in the second week (p=0,047). On the third week, the second factor was introduced by the offering of solid feed (0,4% MOS). During the suckling period, from birth to 21 days of age, a numerical advantage in weight gain was observed for MOS sows piglets (p=0,0989). The sows themselves did not differ in weight change or feed consumption. At 23 &plusmn; 1,91 days of age, weaning was conducted, as piglets were transferred to nursing facilities and allocated in pens of 4 animals. Weight of MOS sows piglets was higher at weaning (p<0,001) and until the 5th week port-weaning. Feed consumption was affected by MOS supplementation of sows and by the higher weaning weight (p=0,0049), directly influencing weight gain, which was superior in the 2nd week. Feeding MOS to piglets enhanced feed consumption (p=0,0784) and feed conversion (p=0,0103) on the 2nd week. At 14 days of age, blood samples were collected for hemogram analysis and an oral dose of 108 CFU of Salmonella Typhimurium administered. Fecal consistency and rectal temperature were evaluated for 28 and 9 days, respectively. Piglets treated with MOS and MOS sows\' piglets tended to show a peek of hyperthermia earlier (p=0,0629 e p=0,0976, respectively). Piglets fed with MOS tended to show a lower temperature peek (p=0.0989). In the last week, MOS sows\' piglets show a higher feed consumption (p=0.0007) and a numerically inferior Salmonella incidence in mesenteric lymph nodes and feces 36 days after the bacterial challenge. In conclusion, supplementing primiparous sows with MOS during gestation and lactation can enhance their body weight gain and the performance and intestinal health of the offspring during the suckling and nursing period

Patterns of oral anticoagulant use and outcomes in Asian patients with atrial fibrillation: a post-hoc analysis from the GLORIA-AF Registry

Background: Previous studies suggested potential ethnic differences in the management and outcomes of atrial fibrillation (AF). We aim to analyse oral anticoagulant (OAC) prescription, discontinuation, and risk of adverse outcomes in Asian patients with AF, using data from a global prospective cohort study. Methods: From the GLORIA-AF Registry Phase II-III (November 2011-December 2014 for Phase II, and January 2014-December 2016 for Phase III), we analysed patients according to their self-reported ethnicity (Asian vs. non-Asian), as well as according to Asian subgroups (Chinese, Japanese, Korean and other Asian). Logistic regression was used to analyse OAC prescription, while the risk of OAC discontinuation and adverse outcomes were analysed through Cox-regression model. Our primary outcome was the composite of all-cause death and major adverse cardiovascular events (MACE). The original studies were registered with ClinicalTrials.gov, NCT01468701, NCT01671007, and NCT01937377. Findings: 34,421 patients were included (70.0&nbsp;±&nbsp;10.5 years, 45.1% females, 6900 (20.0%) Asian: 3829 (55.5%) Chinese, 814 (11.8%) Japanese, 1964 (28.5%) Korean and 293 (4.2%) other Asian). Most of the Asian patients were recruited in Asia (n&nbsp;=&nbsp;6701, 97.1%), while non-Asian patients were mainly recruited in Europe (n&nbsp;=&nbsp;15,449, 56.1%) and North America (n&nbsp;=&nbsp;8378, 30.4%). Compared to non-Asian individuals, prescription of OAC and non-vitamin K antagonist oral anticoagulant (NOAC) was lower in Asian patients (Odds Ratio [OR] and 95% Confidence Intervals (CI): 0.23 [0.22-0.25] and 0.66 [0.61-0.71], respectively), but higher in the Japanese subgroup. Asian ethnicity was also associated with higher risk of OAC discontinuation (Hazard Ratio [HR] and [95% CI]: 1.79 [1.67-1.92]), and lower risk of the primary composite outcome (HR [95% CI]: 0.86 [0.76-0.96]). Among the exploratory secondary outcomes, Asian ethnicity was associated with higher risks of thromboembolism and intracranial haemorrhage, and lower risk of major bleeding. Interpretation: Our results showed that Asian patients with AF showed suboptimal thromboembolic risk management and a specific risk profile of adverse outcomes; these differences may also reflect differences in country-specific factors. Ensuring integrated and appropriate treatment of these patients is crucial to improve their prognosis. Funding: The GLORIA-AF Registry was funded by Boehringer Ingelheim GmbH

Safety of hospital discharge before return of bowel function after elective colorectal surgery

© 2020 BJS Society Ltd Published by John Wiley & Sons LtdBackground: Ileus is common after colorectal surgery and is associated with an increased risk of postoperative complications. Identifying features of normal bowel recovery and the appropriateness for hospital discharge is challenging. This study explored the safety of hospital discharge before the return of bowel function. Methods: A prospective, multicentre cohort study was undertaken across an international collaborative network. Adult patients undergoing elective colorectal resection between January and April 2018 were included. The main outcome of interest was readmission to hospital within 30 days of surgery. The impact of discharge timing according to the return of bowel function was explored using multivariable regression analysis. Other outcomes were postoperative complications within 30 days of surgery, measured using the Clavien–Dindo classification system. Results: A total of 3288 patients were included in the analysis, of whom 301 (9·2 per cent) were discharged before the return of bowel function. The median duration of hospital stay for patients discharged before and after return of bowel function was 5 (i.q.r. 4–7) and 7 (6–8) days respectively (P < 0·001). There were no significant differences in rates of readmission between these groups (6·6 versus 8·0 per cent; P = 0·499), and this remained the case after multivariable adjustment for baseline differences (odds ratio 0·90, 95 per cent c.i. 0·55 to 1·46; P = 0·659). Rates of postoperative complications were also similar in those discharged before versus after return of bowel function (minor: 34·7 versus 39·5 per cent; major 3·3 versus 3·4 per cent; P = 0·110). Conclusion: Discharge before return of bowel function after elective colorectal surgery appears to be safe in appropriately selected patients
