Objective:To compare the effectiveness of an evidence-based bundle in minimizing cesarean section(CS)-related surgical site infections(SSIs)with that of standard routine ***:This was a single-center,parallel,and randomized clinical trial conducted at KAHER’s *** Kore Charitable Hospital,Belagavi,India,from January 2021 to December 31,*** hundred twenty women undergoing CS delivery were selected and allocated into two groups(1:1)using simple randomization with fixed *** evidence-based surgical bundle(a combination of more than three perioperative interventions)was used for the intervention group,whereas the control group received routine standard perioperative *** primary outcome was the incidence of SSI(superficial,deep,and organ or space SSIs)within 6 weeks postpartum in both *** and continuous data were analyzed using appropriate statistical tests with a significance threshold set at P<***:In this study,16 and 17 participants each from the control and intervention groups,respectively,were lost to follow-up,resulting in a total of 144 and 143 study participants included in the respective ***-eight(19.4%)and 14(9.8%)women developed SSI in the control and intervention groups,respectively(P=0.02).Methicillin-resistantStaphylococcus aureus was the most common cause of SSI in both groups(63.6%(7/11)and 100%(3/3)in the control and intervention groups,respectively).Conclusion:The use of the evidence-based bundle for CS-related SSI prevention effectively decreased the incidence of SSI by half compared to standard routine *** the use of this bundle in routine perioperative care will reduce the cost of CS and improve health outcomes in CS.

家禽可提供优质的蛋白质和微量营养物质。在家禽生产中,饲料是主要的投入品,其成本占总生产成本的70%~75%。家禽的饲料主要由谷物组成,能为家禽提供所需的能量。然而,这些谷物含有不同水平的抗营养因子,如非淀粉多糖。由于家禽自身缺乏重要的内源性酶(碳水化合物酶),无法消化这些非淀粉多糖,从而会增加肠道食糜的黏度,影响营养物质的运输和吸收。这些非淀粉多糖还可通过引起肠道微生物群对可消化营养物质的竞争增加家禽感染有害微生物的机会。这不仅会影响家禽的健康,还会增加生产成本。因此,找到效率高和起作用的解决方法极为重要。在非淀粉多糖含量高的日粮中添加碳水化合物酶是解决方案之一,对家禽生产具有重要的作用。多年来,饲用酶一直被用于提高动物消化率和生产性能,但对某些饲料原料的活性有限。新一代碳水化合物酶具有广泛的活性和稳定性,有助于降解日粮中复杂的底物,提高家禽的生产性能。本综述总结了使用碳水化合物酶改善家禽生产性能和肠道健康的最新研究成果。
