BACKGROUND: Chronic exposure of high glucose (HG) in endothelial cell induces senescence which may contribute to the development and progression of age-related diseases including insulin resistance. Andrographis paniculata improves insulin resistance in recent in vitro and in vivo studies. Anti-inflammatory and antioxidant properties of A. paniculata may be the new therapeutic approach to inhibiting premature senescence. However, the senolytic effect of A. paniculata on endothelial cells has not been investigated comprehensively. This study was conducted to evaluate the effect of A. paniculata extract on HG-induced endothelial cell senescence and the underlying mechanisms.METHODS: Human umbilical vein endothelial cells (HUVECs) were treated with 33 mM HG and 7.5 μg/mL A. paniculata extract for 48 hours. The expressions of p16, p21, interleukin (IL)-6, IL-8, insulin receptor substrate (IRS)-1, mammalian target of rapamycin, and sirtuin 1 (SIRT1) were measured by performing real-time quantitative polymerase chain reaction (RT-qPCR). The senescence-associated-β-galactosidase (SA-β-gal) staining was performed to observe the positive-stained senescent cells, while the cell surface expression of IL-1α was examined with flow cytometry method.RESULTS: A. paniculata extract reversed senescence in HUVECs under HG conditions by reducing mRNA expressions of p16 and p21, the number of SA-β-gal-positive-stained cells, and the expression of IL-1α on cell surface, which decreased the activation of IL-6 and IL-8. In addition, A. paniculata extract decreased the mRNA expression of mTOR and increased the mRNA expressions of IRS-1 as well as SIRT1.CONCLUSION: A. paniculata extract ameliorated senescence and improved insulin sensitivity by regulating the mTOR, SIRT1, and IRS-1 mRNA expressions on HG-treated HUVECs.KEYWORDS: Andrographis paniculata, endothelial cell, senescence, high glucose, nutrient-sensing pathways

The Use of Cognitive Task Analysis to Improve Anesthesia Skills Training for Postoperative Extubation
Authors: Embrey, Ed.D, CRNA Karen , Yates, Ed.D Kenneth
Published: August 2024

This study examines knowledge gains in 25 nurse anesthesia trainees, following the implementation of a novel instructional design, which incorporated cognitive task analysis (CTA) to teach an adult postoperative extubation procedure. CTA is a knowledge elicitation technique employed for acquiring expertise from domain specialists to support the effective instruction of novices. Instruction guided through CTA is effective in improving surgical skills training for medical students and surgical resi-dents. The standard, current method of teaching clinical skills to novices in nurse anesthesia practice relies on recall-based instruction from domain experts. However, this method is limited by the constraints of expertise, including automation of procedural knowledge by the expert practitioner.Automated knowledge escapes conscious awareness and access, thus impeding clear explication of comprehensive essentials for task execution during instruction. CTA guided instruction has been shown to maximizeconceptual, declarative and procedural knowledge gains in novice practitioners by clearly explicating the essentials employed when experts execute tasks. Knowledge gains for the task of postoperative extubation in 13 junior and senior nurse anesthesia trainees were compared to those of 12 trainees, receiving standard instruction. The study results indicate that CTA-based instruction has a positive and significant effect on procedural knowledge gains in the novice anesthetist.

Authors: Tracey, MSN, CRNA Andy
Published: August 2024

Purpose: Understanding student nurse anesthetists’ views on nurse anesthetist role transition.Design and Methods: Three focus groups were conducted with a total of 17 nurse anesthesia students. Nurse Anesthesia Programs in the Chicago area were contacted to elicit volunteers.  Discussions were audiotaped and transcribed verbatim. Thematic analysis using constant comparison was completed within and across focus groups.Findings: Nurse Anesthesia students defined successful role transition from RN to CRNA as the ability to function independently with minimal backup or assistance while ensuring patient safety through a successful anesthetic. The following themes were identified as factors affecting SRNAs’ successful role transition: Preceptor, Mentoring, Reflection, Training Variety, and CRNA role modeling.Conclusions: Perceptions on what factors affect the role transition from RN to CRNA vary depending upon the level of training SRNAs have had in their anesthesia program. SRNAs nearing the end of their training have a firmer grasp on which factors affect their transition. This pilot study has allowed this researcher to examine the perceptions of SRNAs at different levels in their training and allowed for future changes in planning for a full study.

Authors: Rabbani, CRNA, MS Robbin , Gold, CRNA, PhD Michele E.
Published: August 2024

Considerable surgical blood loss is a recognized complication of hepatic surgery. Allogeneic blood product transfusion can be used to treat anemia related to surgery. However, research has shown that transfusing blood products exposes the patient to multiple risk factors. Methods of surgical and anesthetic management of blood loss such as establishing acute normovolemic hemodilution and maintaining low central venous pressure can prevent the need for a transfusion. This case study outlines the use of acute normovolemic hemodilution and low central venous pressure to prevent allogeneic blood transfusion in a patient undergoing hepatic resection.
Debunking Volatile Anesthetic Cost Myths Between Sevoflurane and Desflurane
Authors: Varkey John , Welliver, CRNA, DNP Mark
Published: August 2024

Inhalational agents have been a mainstay in anesthesia practice. Nitrous oxide, the world’s first inhalational agent, was synthesized in 1772 and is still in use today. By the late 1800s diethyl ether, and chloroform, volatile anesthetic agents (VAAs) were introduced and administered by anesthesia professionals to facilitate surgery.  Volatile anesthetic agents, while inhalation agents, were liquids as opposed to a gas at room temperature. Therefore, VAAs were inhalation agents that were volatile (evaporated) emitting gases that produced anesthesia. Halogenated (addition of Cl, Fl, Br) hydrocarbon chain VAAs were created in the 1940s and were safer, more stable, and more potent anesthetic agents. The early VAAs had negative side effects and properties that included flammability, high incidence of nausea and vomiting, and high tissue solubilities causing prolonged wake up times (emergence). In order to meet the growing needs for a rapid acting and dissipating anesthetic agent for surgery, lower solubility volatile anesthetic agents (VAAs) were created: isoflurane (1981), desflurane (1992), and sevoflurane (1995). Nurse anesthetists have better control and timing of their anesthetic technique by using these lower solubility agents. The two newest and relatively more expensive agents, sevoflurane and desflurane, have many benefits including faster induction and emergence. Using sevoflurane or desflurane may or may not increase the cost of anesthesia when compared to older VAAs. Is it beneficial to choose one of these newer agent’s based on cost differences between the two?  Determining the actual cost of specific VAAs is important to many individuals and institutions that attempt to buffer the rising cost of healthcare by cost effective use of drugs and therapies.
Intravenous Magnesium Sulfate for Multimodal Analgesia
Authors: Noland Ashley
Published: August 2024

Purpose Statement
Magnesium Sulfate has been used as a multimodal approach for analgesia as it may reduce opioid consumption in the first 24 hours after surgery and decrease post-operative pain scores.
Introduction
The use of intraoperative opioids for analgesia is associated with postoperative side effects such as respiratory depression, ileus, nausea, and vomiting. The side effects from opioids can prolong hospital stay and cause patient dissatisfaction. Magnesium acts as a N-methyl-D-aspartate (NMDA) receptor antagonist resulting in an analgesic effect, which can be used as an alternative or adjunct to opioids for pain control.
Literature Review
Magnesium sulfate may be beneficial for multimodal pain management as it reduces opioid requirements and postoperative pain. Targeting various receptors in the pain pathway can optimize analgesia and reduce side effects. Magnesium antagonizes the NMDA receptor and blocks calcium channels to modulate pain and inflammatory responses. Perioperative magnesium administration should be considered as a strategy to reduce postoperative pain in patients undergoing surgical procedures.
Description of the Case
A 67-year-old female presented for a bilateral breast revision, bilateral blepharoplasty of upper lids, neck rhytidectomy, and fat graft injection surgery. The patient had a history of postoperative nausea and vomiting. During the maintenance phase of anesthesia, fentanyl 50 mcg was given as needed for signs of pain, rocuronium was re-dosed to maintain paralysis, and ephedrine and phenylephrine were administered to maintain blood pressure. Intravenous magnesium sulfate 2 g was administered as a multimodal approach to analgesia to decrease post-operative opioid consumption and to prevent post-operative nausea and vomiting. The following day the patient tolerated a regular diet, pain was well controlled, and was hemodynamically stable. The patient was discharged home without complications.
Discussion and Conclusion
Magnesium sulfate may be beneficial for multimodal pain management as it reduces opioid requirements and postoperative pain. Magnesium antagonizes the NMDA receptor and blocks calcium channels to modulate pain and inflammatory responses. It is unclear which mode of magnesium administration provides an advantage to the analgesic effects. The differences in age and gender-related responses to magnesium for analgesia is undetermined. Further research is necessary to examine the use of intravenous magnesium sulfate for postoperative pain in different patient populations, safe and effective dosing ranges, and the effects of analgesia in various surgeries. Intravenous magnesium sulfate should be considered in multimodal analgesic treatment as an adjunct for postoperative analgesia.

Selection of the method for determination of ignition delay of hypergolic propellants
Authors: Boruc Łukasz , Kapusta Łukasz Jan , Kindracki Jan
Published: August 2024

Ignition delay is one of the most important parameters characterising hypergolic propellants. This parameter has a strong im-pact on thruster operation, especially during the cold start. Ignition delay influences the intensity of pressure rise and its peak values during the start of a thruster. High-pressure levels cause stress inside the chamber wall, which directly affects durability and safety. One of two measurement techniques is usually chosen to determine the ignition delay: visual and pressure-based methods. Visual methods are based on high-speed imaging and subsequent image analysis. In the pressure-based method, the pressure trace is analysed. In this study, both techniques were used together and compared in terms of ignition delay determination of hypergolic propellants igniting during the drop tests. The advantages and disadvantages of both techniques were indicated and described. In the setup used in the study, the visual method was found to be more accurate and reliable.
Karihwaientáhkwen: Conceptualizing Morality in Indigenous Consciousness
Authors: Deer Frank , Heringer Rebeca
Published: August 2024

Many public institutions, including universities and colleges, have committed to Indigenous engagement – the institutional effort to engage with experiences, histories, and perspectives of First Nations, Inuit, and Métis peoples in meaningful ways. In many areas of institutional endeavour, these commitments have frequently included a focus upon spiritual orientations of Indigenous peoples as a central aspect of their knowledge and worldviews. In this study, we sought to acquire knowledge on moral understandings that were resident in the consciousness of Indigenous Elders and Knowledge Keepers situated at universities across Canada. Findings revealed that personal and communal experiences informed a developed sense of responsibility that may be situated in the unique manifestations of their respective knowledge systems, heritages, and consciousnesses. Although non-Indigenous orientations such as those of Christianity informed the narratives of some, a prevailing sense of traditional identity emerged from participants.

Published: August 2024

As the manufacturing industry expands in both scale and energy consumption, the challenge of achieving green and sustainable development becomes more prominent. One effective approach to this challenge is reducing product energy consumption by selecting appropriate process parameters. Process parameters in fused deposition modeling (FDM) play a crucial role in determining the energy consumption during the manufacturing process. Accurately forecasting how these parameters affect energy consumption is essential for realizing green manufacturing in FDM. This paper proposes a method for predicting energy consumption in FDM using Bayesian-optimized random forests (BO-RF). First, response surface methodology (RSM) is utilized to design experiments, obtain the sample datasets, and identify four significant factors affecting processing energy consumption. Then, the sample datasets are partitioned into training and testing subsets; Bayesian optimization is used to optimize the model parameters of the RF, thereby obtaining the prediction model. Finally, using mean square error (MSE), mean absolute percentage error (MAPE), mean percentage error, and coefficient of determination as evaluation metrics, the BO-RF model’s predictive performance is evaluated against nine other prediction models. The results demonstrate the BO-RF prediction model’s superiority over nine other models.
