Preliminary study on blood coagulation and hemostatic effect and acute toxicity of Oxalis corniculata L. ethanol extract

In the present study, we aimed to observe the effects of ethanol extract of Oxalis corniculata L. on bleeding time (BT) and coagulation time (CT) and determine its acute toxicity in mice. Firstly, the ethanol extract of O. corniculata was administered to 40 mice, which were randomly divided into the normal control group, Yunnan Baiyao control group, low-dose group, and high-dose group. The low-dose (0.6 g/kg) and high-dose (1.2 g/kg) groups received ethanol extract of O. corniculata by gavage, and the BT and CT of the mice were measured by the slide method and tail clipping method, respectively. Secondly, the median lethal dose method was used with 50 mice to observe the physiological state, poisoning reaction, and death of the mice after intragastric administration. Finally, on the 14th day of the experiment, a necropsy was performed to observe any abnormality of the organs. In conclusion, in the coagulation and hemostasis tests, there were no statistical differences between the groups (P > 0.05), while there was a significant dose-response relationship, and the BT and CT were significantly shorter than those of the negative control group, which were comparable to the Yunnan Baiyao control group. Moreover, in the acute toxicity test, the median lethal dose of ethanol extract of O. corniculata was 6.0291 g/kg, with a 95% confidence interval of 5.3065–6.7829 mg/kg.     

Building a Culturally Responsive Workforce: Faculty of Color in Nursing Education

The representation of nursing faculty of color is disproportionate to that in the general population, despite recruitment and retention strategies. Boosting the presence of nursing faculty of color requires an understanding of factors that undermine diversity initiatives and calls for the adoption of innovative practices. This article addresses the importance of racial and ethnic diversity within nursing education. Furthermore, it examines the factors that prevent the recruitment and retention of a racially and ethnically diverse nursing faculty workforce and provides evidence-based recommendations for increasing diversity among nursing faculty and nursing organizations.

Healthcare professionals’ knowledge,skills, and role in offering and facilitating memory making during end-of-life care in the adult intensive care unit

BackgroundAn activity to provide a tangible keepsake following the death of a loved one is termed ‘memory making’. However, limited evidence is available related to professionals' education and support to provide memory making opportunities in the adult intensive care unit (ICU). Having a greater understanding of healthcare professionals’ experiences can inform future patient/family care and support for professionals in end-of-life care.ObjectiveThe objective of this study was to describe what participants perceive memory making to be, if they have facilitated memory making activities as part of their practice, if they perceive it as part of their role, and if they have the necessary skills to do so.MethodsSeventy-five registered nurses (75% response rate), 19 medical doctors (76% response rate), and two social workers (66.7% response rate) completed a survey at a single tertiary referral centre in an adult ICU.ResultsParticipants reported memory making to include the creation of tangible keepsakes as well as nontangible activities. Overall, participants reported high agreement scores that the responsibility for initiating memory making predominately belonged to the nurse. Participants reported skills most needed involved the ability to interact with the family, being open to the concept, and integrating memory making into their standard of care. Having developed a rapport with families was considered an enabler, whereas lack of knowledge and clinical workload were reported as inhibitors to offering memory making.ConclusionsOverall, participants in this study reported positive experiences with offering memory making to families during end-of-life care in the adult ICU. Nurses are more likely to perceive professional responsibility for offering memory making, likely due to their increased time at the bedside and higher prominence and leadership in other end-of-life practices. To support professionals, education should include conceptual knowledge, procedural knowledge of keepsake creations, communication techniques using reflective practices, and organisational support to facilitate time requirements.     

英语学界对“母乳不足”现象的认知进化

“母乳最好”的宣传话语在目前育龄人群中几乎耳熟能详,但很多信奉科学育儿、希望母乳喂养的都市女性却发现母乳喂养困难重重,其中遭遇“母乳不足”的案例较为多见。回顾历史发现,“母乳不足”的现象全球普遍存在,这个话题在20世纪80年代的英语学术圈曾引起热议。经过十余年讨论后,学者们基本认同大部分遭遇母乳不足的女性并不是真正的“母乳不足”,而是由于种种社会文化因素干扰造成母乳喂养失败的这一结论,其中产后初期的奶瓶介入是重要原因。术语也由insufficient milk syndrome变为perceived insufficient milk,以此来强调“母乳不足”不是一种病理现象,而更多是一种文化感知。     

A historical analysis of vaccine mandates in the United States military and its application to the COVID-19 vaccine mandate

The Department of Defense has implemented a mandate that all military personnel be vaccinated against COVID-19. This article reviews the historical precedent of vaccine mandates for United States military personnel dating back to the formation of the continental army, as well as previous controversies about vaccine mandates such as the first influenza vaccine mandate and the Anthrax Vaccine Immunization Program. The historical review discusses precedent for the current COVID-19 vaccine mandate and the reception of these vaccine mandates by military personnel. The review then discusses how these historical lessons can inform the present COVID-19 vaccine mandate.
