Assessment of the Benefits of Targeted Interventions for Pandemic Control in China Based on Machine Learning Method and Web Service for COVID-19 Policy Simulation

Taking the Chinese city of Xiamen as an example, simulation and quantitative analysis were performed on the transmissions of the Coronavirus Disease 2019(COVID-19) and the influence of intervention combinations to assist policymakers in the preparation of targeted response measures. A machine learning model was built to estimate the effectiveness of interventions and simulate transmission in different scenarios. The comparison was conducted between simulated and real cases in Xiamen. A web inter...     

Clinical Simulation Augments Traditional Interviewing of Advanced Practice Provider Candidates

An essential role of critical care advanced practice providers—advanced practice registered nurses and physician assistants—is to have knowledge and competency to make accurate and efficient decisions. The ability to manage clinical scenarios involving medically deteriorating patients requires higher-order cognitive thinking and leadership skills that are challenging to extrapolate in traditional interviews. In critical care, advanced practice providers must make rapid clinical assessments and implement appropriate medical interventions to deter progression of life-threatening illnesses. Adding clinical simulation to the traditional interview allows interviewers to evaluate applicants’ crisis resource management skills, leadership, and clinical competency.     

The scope of computerized simulation in competency-based maxillofacial training: a systematic review

Oral and maxillofacial surgery (OMS) teaching is set to undergo a paradigm shift towards competency-based training. With increasing focus on resident skill development and patient safety, computerized simulators are likely to play a more mainstream role in OMS training. A systematic review of the available literature was conducted, in accordance with the PRISMA guidelines, to highlight the scope of computerized simulation in OMS teaching. A PubMed search was performed by two independent reviewers, and 35 articles published in English between 2010 and 2021 that reported the use of computerized simulation for teaching maxillofacial procedures were included in the analysis. Eight articles on minor oral surgery, seven on orthognathic surgery, five on maxillofacial trauma, five on cleft lip and palate surgery, three articles each on nerve block techniques, endoscopic procedures, and reconstructive surgery, and one article on fibre-optic intubation reported the use of computerized simulation that can be applied to OMS training. Ten randomized controlled trials were identified in the search. However there was marked heterogeneity among the studies. Simulator training for skill acquisition mentored by an expert OMS educator could offer holistic resident training; however more studies that test common themes of resident training such as knowledge acquisition and skill development are necessary.     

Strategies to optimize comprehension of numerical medication instructions: A systematic review and concept map

ObjectiveTo develop evidence-based recommendations for improving comprehension of quantitative medication instructions.MethodsThis review included a literature search from inception to November 2021. Studies were included for the following: 1) original research; 2) compared multiple formats for presenting quantitative medication information on dose, frequency, and/or time; 3) included patients/lay-people; 4) assessed comprehension-related outcomes quantitatively. To classify the studies, we developed a concept map. We weighed 3 factors (risk of bias in individual studies, consistency of findings among studies, and homogeneity of the interventions tested) to generate 3 levels of recommendations.ResultsTwenty-one studies were included. Level 1 recommendations are: 1) use visualizations of medication doses for liquid medications, and 2) express instructions in time-periods rather than times per day. Level 2 recommendations include: validate icons, use panels or tables with explanatory text, use visualizations for non-English speaking populations and for those with low health literacy and limited English proficiency.ConclusionsVisualized liquid medication doses and time period-based administration instructions improve comprehension of numerical medication instructions. Use of visualizations for those with limited health literacy and English proficiency could result in improved outcomes.Practice implicationsPractitioners should use visualizations for liquid medication instructions and time period-based instructions to improve outcomes.     

Physiologically-based pharmacokinetic modeling for mirabegron: a multi-elimination pathway mediated by cytochrome P450 3A4, uridine 5'-diphosphate-glucuronosyltransferase 2B7, and butyrylcholinesterase

1. This was the first study to construct a physiologically-based pharmacokinetic (PBPK) model for mirabegron which incorporates the overall elimination pathways of metabolism by cytochrome P450 (CYP) 3A4, uridine 5'-diphosphate-glucuronosyltransferase (UGT) 2B7, and butyrylcholinesterase (BChE) and renal excretion. The objective was to assess the risk of drug-drug interactions (DDIs) by estimating the contribution of each elimination pathway and simulating the magnitude of the DDIs with UGT2B7 inhibitors.

2. A PBPK model for mirabegron was constructed to reproduce the plasma concentration-time curves from a phase 1 study and the magnitude of the DDI with ketoconazole taking into account the overall elimination pathways. The PBPK model was subsequently verified using data from other DDI studies.

3. The constructed PBPK model estimated the contribution for each elimination pathway: 44% and 29% for CYP3A4 and UGT2B7 in the liver, 1.6% for UGT2B7 in the kidney, 3.2% for BChE in plasma, and 22% for renal excretion.

4. Co-administration of probenecid (an UGT2B7 inhibitor) or fluconazole (an UGT2B7 and CYP3A4 inhibitor) was predicted to increase area under the curve for mirabegron to 115% or 174%, respectively.

5. In conclusion, PBPK modeling and simulation revealed a low DDI risk for mirabegron following co-administration with BChE or UGT2B7 inhibitors.

     

Numerical Investigation of Analytical Models of Drug Flux Through Microporated Skin

In this study, drug flux through microporated skin was modeled using detailed numerical solution of the diffusion equation. The results of the modeling were compared to previously published simplified and easy to use analytical equations. Limitations and accuracy of these equations were investigated. Appropriate modifications of the equations were identified to expand them to wider practical applications when pore shape is not circular. Numerical simulations have shown a good accuracy of the new simple equations when these are used within their limits of application.     

情境模拟案例教学法在护士规范化培训中的应用效果

目的研究情境模拟案例教学法在护士规范化培训中的应用效果。方法选择2017年8月-2018年7月在医院外科系统进行规范化培训的护士60名作为对照组,接受常规模式的规范化培训;而选择2018年8月-2019年7月进行规范化培训的护士60名作为研究组,在规培期间引入情境模拟案例教学法。规培结束后,考核并比较两组规培护士的理论知识和临床护理操作,测评规培护士的评判性思维能力,调查规培护士对规培模式的满意度。结果对照组的理论知识和临床护理操作的得分分别是(86.7±7.5)分、(82.8±8.7)分,而研究组的得分则分别是(91.3±8.4)分、(87.5±8.1)分;与对照组相比,研究组护士对理论知识的掌握和临床护理操作技能更强(P<0.05)。与对照组相比,研究组规培护士具有更强的批判性思维能力(P<0.05)。而且,研究组护士对情境模拟案例教学模式的满意度要优于对照组(P<0.05)。结论情境模拟案例教学法在护士规范化培训中效果较好,可显著提高规培护士的理论及实践操作的综合能力以及评判性思维能力。
