European pig production faces economic and environmental challenges. Modelling can help farmers simulate and understand how changes in their management practices affect the efficiency of their production system. We developed an individual-based model of a pig-fattening unit that considers individual variability in performance among pigs, farmers' feeding practices and animal management and estimates environmental impacts (using life cycle assessment) and economic results of the unit. We previously demonstrated that this model provides reliable estimates of farm performance for different combinations of management practices, pig types and building characteristics. The objectives of this study were to quantify how interactions between feeding practices and animal management influence fattening unit results in healthy or impaired health conditions using the model. A virtual experiment was designed to evaluate effects of interactions between feeding practices, health status of the pig herd and infrastructure consimilar to healthy populations with 2P ad libitum feeding and 7 days batch interval. Restricted, DP and individual feeding plans improved the economic and environmental performances of the unit for both health statuses. This study highlighted that health status of the pig herd is the main factor that affects technical, economic and environmental performances of a pig-fattening unit, and that adequate feeding strategies and animal management can compensate, to some extent, the effects of impaired health on environmental impacts but not on gross margin.Automated weighing systems to monitor BW and supplement intake (SI) of individual grazing cattle are being developed to better understand the seasonal nutrition and performance of grazing livestock. This study established (1) the accuracy and repeatability of a commercial walk-over weighing (WoW) system for estimating BW and (2) the accuracy of an automatic supplement weighing (ASW) unit for estimating SI based on measuring time spent at the unit. The WoW and ASW units monitored BW and SI of 112 cattle consisting of 55 cows and 57 calves grazed on a 32.5 ha paddock for 41 days, with an average of 258 BW records collected per day. Static BWs were recorded at each mustering event (n = 7) and were compared to repeated measurements collected by the WoW on the day of each mustering event. Body weight was overestimated by the WoW, with the predicted BW of calves and cows averaging 10 and 21 kg heavier, respectively, than actual, and root MS prediction errors (RMSPE) of 5.1% and 5.5% of the static BW, respectively. c BW, the low bias in the slope indicated that a linear regression model could be developed to adjust the WoW BW to reduce the MB and improve the estimate of WoW BW. The significant positive relationship between time spent at the ASW unit and individual blood FBZ concentration identified the suitability of the ASW unit for estimating SI by grazing cattle.It is known that pigs can acquire flavour preferences by brief social interactions with conspecifics that previously consumed a flavoured solid feed. However, there is no information about whether a flavoured solution could support flavour preferences through social transmission. Ninety-six pigs (49 days old) were housed in 12 pens (8 pigs/pen). Four animals per pen were randomly selected to act as observers and four as demonstrators. Demonstrator animals were temporarily moved to an empty pen where a protein solution was offered (porcine digestive peptides (PDPs), 4% weight/volume) with the addition of 0.075% aniseed (six pens) or garlic (six pens) powdered artificial flavours for 30 min. Afterwards, demonstrators were returned to interact with observer animals for 30 min. A choice test (30 min) between aniseed and garlic PDP was performed for each observer group after the interaction. Observers showed a higher intake of solutions previously consumed by their demonstrator conspecifics (648 v. 468 ml; SEM 61.36, P less then 0.05). As with flavoured solid feeds, protein solutions containing artificial flavours can create preferences in pigs for those flavours through social transmission from conspecifics.At present, pay for prescription models are insufficient at containing costs and improving access to medicines. Subscription financing through tenders, licensing fees and unrestricted or fixed volumes can benefit stakeholders across the supply chain. Pharmaceutical manufacturers can reduce the need for marketing expenses and gain certainty in revenue. selleck chemicals llc This will decrease costs, improve predictability in budget expenditure for payers and remove price as a barrier of access from patients. Inherently, low- and middle-income countries lack the purchasing power to leverage price discounts through typical price arrangements. These markets can realise substantial savings for branded and generic medicines through subscription financing. Procuring of on-patent and off-patent drugs requires separate analysis for competition effects, the length of contract and encouraging innovation in the medicine pipeline. Prices of competitive on-patent medicines and orphan drugs can be reduced through increased competition and volume. Furthermore, pooling expertise and resources through joint procurement has the potential for greater savings. Incentivising research and development within the pharmaceutical industry is essential for sustaining a competitive market, preventing monopolies and improving access to expensive treatments. However, technical capacity, forecasting demand and the quality of generic medicines present limitations which necessitate government support and international partnerships. Ultimately, improving access requires progressive financing mechanisms with patients and cost containment in mind.BACKGROUND Endoscopic frontal sinus surgery is frequently complicated by post-operative stenosis and obstruction of the frontal sinus outflow tract, resulting in recurrent disease. Frontal sinus stents may help prevent re-occlusion of the frontal neo-ostia. OBJECTIVE This paper presents a simple and cost-effective approach to frontal sinus stenting using modified Silastic nasal splints. RESULTS AND CONCLUSION The current technique provides an effective, reliable and inexpensive method for achieving post-operative frontal sinus outflow tract patency.Irritable bowel syndrome (IBS) is a chronic disorder characterised by recurrent abdominal pain or discomfort and transit disturbances with heterogeneous pathophysiological mechanisms. The link between food and gastrointestinal (GI) symptoms is often reported by patients with IBS and the role of fructose has recently been highlighted. Fructose malabsorption can easily be assessed by hydrogen and/or methane breath test in response to 25 g fructose; and its prevalence is about 22 % in patients with IBS. The mechanism of fructose-related symptoms is incompletely understood. Osmotic load, fermentation and visceral hypersensitivity are likely to participate in GI symptoms in the IBS population and may be triggered or worsened by fructose. A low-fructose diet could be integrated in the overall treatment strategy, but its role and implication in the improvement of IBS symptoms should be evaluated. In the present review, we discuss fructose malabsorption in adult patients with IBS and the interest of a low-fructose diet in order to underline the important role of fructose in IBS.Using longitudinal data from the first and second waves of the Young Lives Study (YLS) in Ethiopia, India (Andhra Pradesh), Peru and Vietnam, conducted in 2002 and 2006-07, and a repeated measures mixed model, this study examined the effect of the use of solid fuels for cooking on childhood stunting among children aged 5-76 months. The analysis showed that in all four populations, the average height-for-age z-score (HAZ score) was much lower among children living in households using solid fuels than among children in households using cleaner fuels for cooking. The average HAZ score was lower among children living in households that used solid fuels in both waves of the YLS compared with those whose households used solid fuels in only one of the two waves. A significant reduction was noted in the average HAZ score between the two waves in all countries except Ethiopia. The results of the repeated measures mixed model suggest that household use of solid fuels was significantly associated with lower HAZ scores in all populations, except Ethiopia. The findings also indicate that the reduction in the HAZ scores between waves 1 and 2 was not statistically significant by the type of cooking fuel after controlling for potential confounding factors. The study provides further evidence of a strong association between household use of solid fuels and childhood stunting in low- and middle-income countries using longitudinal data. The findings highlight the need to reduce exposure to smoke from the combustion of solid fuels, by shifting households to cleaner cooking fuels, where feasible, by providing cooking stoves with improved combustion of solid fuels and improved venting, and by designing and implementing public information campaigns to inform people about the health risks of exposure to cooking smoke.Evidence has suggested that honey intake has a beneficial impact on glycemic control in patients with type 2 diabetes. Whether these findings apply adults with prediabetes is yet unclear. The aim of the present study was to examine whether honey intake is associated with a lower prevalence of prediabetes. A cross-sectional study was performed in 18,281 participants (mean [standard deviation] age 39.6 [11.1] years; men, 51.5%). Dietary intake was assessed through a validated 100-item food frequency questionnaire. Prediabetes was defined according to the American Diabetes Association criteria impaired fasting glucose, impaired glucose tolerance, or raised glycosylated hemoglobin. Multivariable logistic regression models were used to estimate the association between honey consumption and prediabetes. As compared with those who almost never consumed honey, the multivariable odds ratios (95% confidence interval) of prediabetes were 0.94 (0.86, 1.02) for ≤3 times/week, 0.77 (0.63, 0.94) for 4-6 times/week, and 0.85 (0.73, 0.99) for ≥1 times/day (P for trend less then 0.01). These associations did not differ substantially in sensitivity analysis. Higher honey consumption was associated with a decreased prevalence of prediabetes. More large prospective cohort studies are needed to investigate this association.N-carbamylglutamate (NCG) has been shown to enhance arginine synthesis and improve growth performance in animals. However, the effect of NCG on body fat deposition remains unknown. This study examined the effects of NCG on body fat deposition and evaluated the potential mechanisms involved. 3-month-old Rex rabbits were assigned to one of four dietary groups and supplemented with NCG at the following different concentrations in a feeding trial that lasted 67 days 0 (control), 0.04%, 0.08%, and 0.12%. NCG supplementation increased serum concentrations of arginine and proline by activating intestinal carbamoylphosphate synthase-І at the posttranscriptional level. Final body weights and growth performance were not affected by dietary NCG levels. However, NCG-treated rabbits had lower perirenal and subcutaneous fat percentages, serum triglyceride (TG) content, and hepatic fatty acid synthase (FAS) activity and increased nitric oxide synthase activity and serum levels of nitric oxide (NO), growth hormone (GH), and insulin-like growth factor 1 (IGF-1).
