The captive white-tailed deer industry has an estimated impact of 1.6 billion USD in the state of Texas alone. However, nutritional requirements for cervids are determined through research based on sheep and goats. The objective of this study was to determine the effects of zinc on differences in dry matter digestibility in vitro for white-tailed does (Odocoileus virginianus). Deer (n = 2) were ethically harvested, rumens were collected, and placed into a cooler containing warm water. Rumen contents were agitated, and fluid was filtered using cheese cloth while applying CO2. Fluid was placed into four separate incubator jars with filter bags containing a 1:1 alfalfa to coastal hay blend. Zinc doses of 0.073 mg/kg/d equivalents were added to two of the jars ( Zn), and the additional two jars received 0.00 mg/kg/d (CON). Following 48 h of incubation, in vitro true digestibility (IVTD) showed no significant differences between the control and the treatment groups. Average dry matter digested in vitro was 91.87% and 95.13%, respectively. There were no differences detected in ADF, NDF, IVTD, or Om between the treatment groups. While no detectable differences were observed in this study, this methodology did prove to be viable and functional for microbial digestion in vitro. This study can be replicated with multiple experimental units to confirm the observations of increased digestibility. Formal nutritional guidelines can be created to allow for more efficient feeding of cervids thereby reducing feed costs and continuing the growth of the captive deer industry.

目的旨在对目前提供急性照护的医院识别认知障碍患者以及在病历中记录和管理认知相关信息的实际情况及政策要求和推荐方法进行综述。方法采用Whittemore和Knaf1的五步法,系统检索medline,CINAHL和Scopus数据库,并检索了灰色文献来源。纳人了提供急性照护的医院已实施的患者认知障碍识别和认知信息管理相关的文献。采用混合方法评价工具和灰色文献质量评估清单对文章质量进行评价。采用主题分析法呈现和整合结果。该综述已在PROSPERO预注册(CRD42022343577)。结果共22篇原始研究文献和10篇政府/行业文件被纳人分析。结果显示,实践和政策之间存在差距。尽管在政策层面上高度重视认知障碍的识别、认知相关信息的透明度,以及与患者、家属和照顾者(如适用)之间的互动,但有时在临床实践中,认知评估是非正式的,患者的认知相关信息未作记录,与患者、家属和照顾者的互动也存在不足。结论.通过整合认知评估,利用信息技术开发信息管理综合系统,建立相关法律法规,提供教育与和培训,并采用国家层面的策略,有可能显著改善对认知障碍患者的识别和护理。

Due to an isolated error in the 3D simulation parameters,the laser energy and intensity(calculated using the energy)values were incorrectly stated as 10.9 J and 3×10^(22) W cm^(−2),respectively,in Sections 3.3,7 and *** correct values are 39.8 J and 1.1×10^(23) W cm^(−2).Similarly,the values stated for the higher energy case,109 J and 3×10^(23) W cm^(−2) in Section 7,should be 398 J and 1.1×10^(24) W cm^(−2),respectively.
