1. Building Opportunities and Overtures in Science and Technology: Establishing an Early Intervention, Multi-Level, Continuous STEM Pathway Program

Author

Garcia, Jamie, Gibson, Rebecca A., Breslav, Alexander, Alvarado, Jonnathan Singh, Seas, Andreas, Maduka, Austin, Coleman, Douglass, and Fuller, Anthony T.

Abstract

Building Opportunities and Overtures in Science and Technology (BOOST) is an early intervention, multi-level, continuous STEM pathway program. Born out of a partnership between Duke University and Durham Public Schools, the BOOST program provides 6th through 8th grade students underrepresented in STEM fields with interactive, in-depth explorations of STEM education and STEM careers. BOOST uniquely provides program continuity through high school, undergraduate, and graduate leadership programming. The purpose of this article is to characterize the components of the BOOST program including program background, principles, structure, timeline, and leadership opportunities. BOOST highlights the benefits of integrating early intervention and continuity into the framework of STEM pathway programs. We hope that lessons learned from this program will inform existing programs and encourage the creation of future early intervention, multi-level, continuous STEM pathway programs.

17. Subcallosal cingulate deep brain stimulation evokes two distinct cortical responses via differential white matter activation.

Author

Abstract

Subcallosal cingulate (SCC) deep brain stimulation (DBS) is an emerging therapy for refractory depression. Good clinical outcomes are associated with the activation of white matter adjacent to the SCC. This activation produces a signature cortical evoked potential (EP), but it is unclear which of the many pathways in the vicinity of SCC is responsible for driving this response. Individualized biophysical models were built to achieve selective engagement of two target bundles: either the forceps minor (FM) or cingulum bundle (CB). Unilateral 2 Hz stimulation was performed in seven patients with treatment-resistant depression who responded to SCC DBS, and EPs were recorded using 256-sensor scalp electroencephalography. Two distinct EPs were observed: a 120 ms symmetric response spanning both hemispheres and a 60 ms asymmetrical EP. Activation of FM correlated with the symmetrical EPs, while activation of CB was correlated with the asymmetrical EPs. These results support prior model predictions that these two pathways are predominantly activated by clinical SCC DBS and provide first evidence of a link between cortical EPs and selective fiber bundle activation.

MACHINE learning, MENINGIOMA, SKULL base
Abstract

This article, published in the Journal of Neurological Surgery, explores the use of machine learning and 3D MRI-based analysis to predict the pathologic grade of skull base meningiomas. The study analyzed preoperative MRIs from 38 patients and used a custom machine learning pipeline to predict the grade of the tumor. The results showed that the machine learning model had an area under the receiver operating characteristic curve (AUROC) of 0.75, indicating its potential for predicting the pathologic grade. However, further research with a larger sample size is needed to validate these findings and improve prognostication for patients with skull base meningiomas. [Extracted from the article]

MACHINE learning, MENINGIOMA, LASER-induced fluorescence
Abstract

This article discusses the development of a new technology called "TumorID" that uses machine learning and noncontact fluorescence spectroscopy to analyze meningioma tissue in real-time during surgery. The aim of this technology is to differentiate between Grade 1 and Grade 2 meningiomas, which have different prognostic and management implications. The study found that the multi-layer perceptron and logistic regression models performed the best in predicting the grade of meningiomas, with high accuracy. However, further research is needed to validate these findings on larger sample sizes. The authors hope that this technology will eventually improve the efficiency and accuracy of prognostication for patients with meningiomas. [Extracted from the article]

Abstract

The article discusses the use of ChatGPT, a language model developed for rapid use by the lay audience, in providing accurate medical information for the treatment of lumbar disc herniation with radiculopathy. The study found that both ChatGPT-3.5 and ChatGPT-4.0 provided accurate responses to just over 50% of questions, with nearly half of the responses being overconclusive. The models also provided supplemental information but were noted to have provided incomplete responses to some questions. The article highlights the limitations of using a general language model like ChatGPT for patient care and suggests ways to mitigate the model's inaccuracies and biases. [Extracted from the article]

33. Stent Design Affects Femoropopliteal Artery Deformation.

Author

MacTaggart, Jason, Poulson, William, Seas, Andreas, Deegan, Paul, Lomneth, Carol, Desyatova, Anastasia, Maleckis, Kaspars, and Kamenskiy, Alexey

Abstract

Background: Poor durability of femoropopliteal artery (FPA) stenting is multifactorial, and severe FPA deformations occurring with limb flexion are likely involved. Different stent designs result in dissimilar stent–artery interactions, but the degree of these effects in the FPA is insufficiently understood. Objectives: To determine how different stent designs affect limb flexion-induced FPA deformations. Methods: Retrievable markers were deployed into n = 28 FPAs of lightly embalmed human cadavers. Bodies were perfused and CT images were acquired with limbs in the standing, walking, sitting, and gardening postures. Image analysis allowed measurement of baseline FPA foreshortening, bending, and twisting associated with each posture. Markers were retrieved and 7 different stents were deployed across the adductor hiatus in the same limbs. Markers were then redeployed in the stented FPAs, and limbs were reimaged. Baseline and stented FPA deformations were compared to determine the influence of each stent design. Results: Proximal to the stent, Innova, Supera, and SmartFlex exacerbated foreshortening, SmartFlex exacerbated twisting, and SmartControl restricted bending of the FPA. Within the stent, all devices except Viabahn restricted foreshortening; Supera, SmartControl, and AbsolutePro restricted twisting; SmartFlex and Innova exacerbated twisting; and Supera and Viabahn restricted bending. Distal to the stents, all devices except AbsolutePro and Innova exacerbated foreshortening, and Viabahn, Supera, Zilver, and SmartControl exacerbated twisting. All stents except Supera were pinched in flexed limb postures. Conclusions: Peripheral self-expanding stents significantly affect limb flexion-induced FPA deformations, but in different ways. Although certain designs seem to accommodate some deformation modes, no device was able to match all FPA deformations. [ABSTRACT FROM AUTHOR]

Abstract

Background: Although the study of calcium (Ca2+) is classically associated with excitable cells such as myocytes or neurons, the ubiquity of this essential element in all cellular processes has led to interest in other cell types. The importance of Ca2+ to apoptosis, cell signaling, and immune activation is of special import in cancer. Main: Here we review the current understanding of Ca2+ in each of these processes vital to the initiation, spread, and drug resistance of malignancies. We describe the involvement of Ca2+, and Ca2+ related proteins in cell cycle checkpoints and Ca2+ dependent apoptosis and discuss their roles in cellular immortalization. The role of Ca2+ in inter-cellular communication is also discussed in relevance to tumor-stromal communication, angiogenesis, and tumor microinvasion. The role that Ca2+ plays in immune surveillance and evasion is also addressed. Finally, we discuss the possibility of targeting Ca2+ singling to address the most pressing topics of cancer treatment: metastatic disease and drug resistance. Conclusion: This review discusses the current understanding of Ca2+ in cancer. By addressing Ca2+ facilitated angiogenesis, immune evasion, metastasis, and drug resistance, we anticipate future avenues for development of Ca2+ as a nexus of therapy. [ABSTRACT FROM AUTHOR]
