By integrating key components from previously published advocacy training programs with our recent research, we propose a unifying model to inform the development and execution of advocacy courses for GME trainees. To ensure widespread use of model curricula, and to reach an expert consensus, additional investigation is required.
Building upon core features of advocacy curricula identified in earlier publications and our data, we present a unified model to shape the development and implementation of advocacy curricula for GME trainees. To develop model curricula for dissemination, a crucial step is further research to build expert consensus.

The Liaison Committee on Medical Education (LCME) stipulates that well-being programs must be impactful and successful. Furthermore, a considerable portion of medical schools do not comprehensively assess the impact of their well-being programs. Fourth-year medical students' satisfaction with well-being programs is assessed in a way that is insufficient for evaluating the overall program, through a single, inadequately specific question on the Association of American Medical Colleges' annual Graduation Questionnaire (AAMC GQ). This survey is limited, capturing only one moment during their training. This viewpoint compels the AAMC Group on Student Affairs (GSA) – Committee on Student Affairs (COSA) Working Group on Medical Student Well-being to propose the adaptation of Kern's six-step curriculum development approach as a sound foundation for the development and assessment of student well-being programs. Well-being programs can benefit from the application of Kern's steps, as detailed in our strategies that cover needs analysis, establishing objectives, program implementation, and performance measurement with feedback loops. Although each institution's objectives are uniquely determined by their needs analysis, we offer five illustrative objectives that focus on medical student well-being. A rigorous and structured approach is fundamental in developing and evaluating undergraduate medical education well-being programs. This includes establishing a guiding philosophy, setting explicit goals, and implementing a comprehensive evaluation system. The Kern-founded framework empowers schools to precisely measure the influence of their projects on the well-being of students.

Although cannabis could serve as a substitute for opioids, the efficacy of this substitution, as judged by recent studies, remains a contested issue. Analyses centered on state-wide data frequently fail to capture the critical variations in cannabis access at the granular sub-state level.
Colorado's county-specific data on cannabis legalization and its effect on opioid consumption. Starting January 2014, Colorado embraced the existence of recreational cannabis retail stores. The degree to which local communities embrace cannabis dispensaries will determine the level of exposure to such outlets.
Exploiting county-level variations in recreational dispensary permits, an observational and quasi-experimental research design was employed.
Employing licensing data from the Colorado Department of Revenue, we measure the degree of exposure to cannabis outlets at the county level within Colorado. Utilizing data from the state's Prescription Drug Monitoring Program (2013-2018), we derived opioid prescribing measures, broken down by county and quarter, encompassing the number of 30-day fills and the total morphine equivalent dose per resident. We analyze the outcomes of opioid-related inpatient visits (2011-2018) and emergency department visits (2013-2018) using Colorado Hospital Association data. Applying a differences-in-differences approach with linear models, we incorporate the variations in exposure to medical and recreational cannabis over time. The analysis incorporates data from 2048 county-quarter observations.
At the county level, we observe a combination of evidence regarding cannabis exposure and opioid-related outcomes. A study revealed a significant relationship between increasing recreational cannabis use and a decrease in 30-day prescription refills (coefficient -1176, p<0.001) and inpatient hospitalizations (coefficient -0.08, p=0.003). However, no such effect was found for total morphine milligram equivalents or emergency department visits. Substantial reductions in 30-day prescription fills and morphine milligram equivalents were seen in counties without prior medical marijuana exposure compared to counties with such exposure, following the legalization of recreational use (p=0.002 for both metrics).
The inconsistent results of our study suggest that further increases in cannabis availability, exceeding medical needs, may not always correlate with a decrease in opioid prescriptions or opioid-related hospitalizations on a population-wide scale.
Our mixed research results suggest that boosting cannabis accessibility beyond medical purposes might not universally reduce opioid prescribing practices or opioid-related hospitalizations.

Chronic pulmonary embolism (CPE), a potentially fatal but curable condition, is difficult to diagnose early. Our investigation into recognizing CPE from CT pulmonary angiograms (CTPA) has resulted in the development and testing of a novel convolutional neural network (CNN) model, utilizing the general vascular morphology evident in two-dimensional (2D) maximum intensity projection images.
A CNN model was developed using a carefully chosen subset of the RSPECT public pulmonary embolism CT dataset. This subset encompassed 755 CTPA studies, each accompanied by patient-level labels indicating CPE, acute APE, or the absence of pulmonary embolism. For the purposes of training, CPE patients with a right-to-left ventricular ratio (RV/LV) below 1 and APE patients with an RV/LV ratio of 1 or greater were excluded from the analysis. Local data, comprising 78 patients, underwent additional CNN model selection and testing, excluding no RV/LV-based criteria. We assessed the performance of the Convolutional Neural Network (CNN) using the area under the receiver operating characteristic curve (AUC) and balanced accuracy metrics.
Our ensemble model analysis of the local dataset yielded an AUC of 0.94 and a balanced accuracy of 0.89 for classifying CPE versus no-CPE, with CPE defined as present in one or both lungs.
Utilizing 2D maximum intensity projection reconstructions of CTPA, our newly developed CNN model demonstrates excellent predictive accuracy in distinguishing chronic pulmonary embolism with RV/LV1 from acute pulmonary embolism and non-embolic cases.
The deep learning convolutional neural network model excels at identifying chronic pulmonary embolism from CT angiography with impressive accuracy.
A computational technique for the automated recognition of chronic pulmonary embolism (CPE) from computed tomography pulmonary angiography (CTPA) was devised. Applying deep learning to two-dimensional maximum intensity projection images yielded valuable results. To cultivate the deep learning model, a large, publicly available data set was leveraged. In terms of predictive accuracy, the proposed model performed exceedingly well.
Automatic recognition of Critical Pulmonary Embolism (CPE) in computed tomography pulmonary angiograms (CTPA) was implemented. Deep learning methods were employed to process two-dimensional maximum intensity projection images. The deep learning model's training relied on a considerable public dataset. An excellent level of predictive accuracy was demonstrated by the proposed model.

Recent years have witnessed a rise in opioid-related overdose fatalities in the United States, marked by the growing prevalence of xylazine. immediate delivery Although the exact contribution of xylazine to opioid-related overdose deaths is not fully understood, it is known to significantly depress vital functions, resulting in hypotension, bradycardia, hypothermia, and respiratory depression.
In freely moving rats, we investigated the hypothermic and hypoxic impacts of xylazine, and its blends with fentanyl and heroin, specifically on the brain.
During the temperature experiment, we observed that intravenous xylazine, administered at low, human-relevant dosages (0.33, 10, and 30 mg/kg), systematically reduced locomotor activity and caused a subtle yet prolonged decrease in brain and body temperature. Consistent xylazine dosages in the electrochemical experiment resulted in a dose-dependent decrease in the oxygenation of the nucleus accumbens. In contrast to the relatively weaker and prolonged decreases in brain oxygen triggered by xylazine, intravenous fentanyl (20g/kg) and heroin (600g/kg) induce more prominent biphasic responses. The initial rapid drop, due to respiratory depression, is followed by a slower, more prolonged increase, reflecting a post-hypoxic compensatory phase. Importantly, fentanyl's action is faster than heroin's. Xylazine, when mixed with fentanyl, caused the elimination of the hyperoxic oxygen response phase, leading to a prolonged state of brain hypoxia. This suggests that xylazine diminishes the brain's ability to compensate for hypoxic conditions. P62-mediated mitophagy inducer The xylazine-heroin cocktail considerably heightened the initial decrease in oxygen levels, and the subsequent oxygen pattern lacked the expected hyperoxic phase, implying more substantial and sustained brain hypoxia.
This study implies that xylazine intensifies the deadly effects of opioids, postulating that a reduction in brain oxygen is the culprit in xylazine-positive opioid overdose fatalities.
Research suggests that the presence of xylazine in opioid mixtures enhances the severe risks associated with opioid use, suggesting that a worsening of brain oxygen deprivation might be the underlying cause of xylazine-positive opioid overdose fatalities.
