Changes in Temperature Following Radiofrequency Thermal Ablation of the Nucleus Pulposus and Annulus Fibrosus: A Cadaveric Study.

Background: Various minimally invasive procedures for treating discogenic pain have been reported in recent years. A Disc-FX® system can be used to perform nucleus pulposus (NP) removal, radiofrequency ablation, and annuloplasty under the guidance of x-ray fluoroscopy. However, when a probe tip with focused heat is placed on the intradiscal/subannular area to perform nucleo-annuloplasty using radiofrequency lesioning, thermal injury to the spinal cord or spinal nerves is a concern.

Computational Design of Crescent Shaped Promising Nonfullerene Acceptors with 1,4-Dihydro-2,3-quinoxalinedione Core and Different Electron-withdrawing Terminal Units for Photovoltaic Applications.

This study aims to design a series of nonfullerene acceptors (NFAs) for photovoltaic applications having 1,4-dihydro-2,3-quinoxalinedione fused thiophene derivative as the core unit and 1,1-dicyanomethylene-3-indanone (IC) derivatives and different π-conjugated molecules other than IC as terminal acceptor units.

Shedding light on triple-negative breast cancer with Trop2-targeted antibody-drug conjugates.

Triple-negative breast cancer (TNBC) is well-known as the most aggressive subtype of breast cancer. Because TNBC does not express Her2, estrogen receptor, and progesterone receptors, there had been no effective U.S.

The effect of the COVID-19 pandemic on hip fracture care: our experience at the University Hospitals of Leicester (UHL).

The United Kingdom (UK) Covid-19 pandemic has led to unique changes in the operation of the National Health Service (NHS) including within trauma and orthopaedics. This has led to a significant impact on the NHS ability to provide hip fracture care and sustain emergency surgery. This has led to local hip fracture services changing operations to provide more sustainable care and significant impacts on best practice tariffs.

Confidential machine learning on untrusted platforms: a survey.

With the ever-growing data and the need for developing powerful machine learning models, data owners increasingly depend on various untrusted platforms (e.g., public clouds, edges, and machine learning service providers) for scalable processing or collaborative learning.

A survey of cancer care institutions in Nepal to inform design of a pain management mobile application.

Background: One way to improve the delivery of oncology palliative care in low and middle-income countries (LMICs) is to leverage mobile technology to support healthcare providers in implementing pain management guidelines (PMG). However, PMG are often developed in higher-resourced settings and may not be appropriate for the resource and cultural context of LMICs.

Objectives: This research represents a collaboration between the University of Virginia and the Nepalese Association of Palliative Care (NAPCare) to design a mobile health application ('app') to scale-up implementation of existing locally developed PMG.

Early results of full-endoscopic decompression of lumbar central canal stenosis by outside-in technique: A clinical and radiographic study.

Enhancement of air-stability, π-stacking ability, and charge transport properties of fluoroalkyl side chain engineered n-type naphthalene tetracarboxylic diimide compounds.

In this study, the impact of fluoroalkyl side chain substitution on the air-stability, π-stacking ability, and charge transport properties of the versatile acceptor moiety naphthalene tetracarboxylic diimide (NDI) has been explored. A density functional theory (DFT) study has been carried out for a series of 24 compounds having different side chains (alkyl, fluoroalkyl) through the imide nitrogen position of NDI moiety. The fluoroalkyl side chain engineered NDI compounds have much deeper highest occupied molecular orbitals (HOMO) and lowest unoccupied molecular orbitals (LUMO) than those of their alkyl substituted compounds due to the electron withdrawing nature of fluoroalkyl groups.

Biportal Endoscopic Excision of Facetal Cyst in the Far Lateral Region of L5S1: 2-Dimensional Operative Video.

Unilateral biportal endoscopy (UBE) is a recently introduced technique that utilizes 2 portals, one for endoscopy and one as a working portal, in contrast to full endoscopy, which utilizes a single portal. The advantages are a favorable learning curve and free mobility of instruments in the operative field. UBE is successful in addressing cervical and lumbar disc herniations, lumbar stenosis, and foraminal/extraforaminal pathologies, such as herniations and foraminal stenosis.

Radiographic and clinical outcomes of huge lumbar disc herniations treated by transforaminal endoscopic discectomy.

Objectives: Large Central disc herniations (occupying more than 50% of canal area) are notorious as they are generally associated with worse outcomes and are technically difficult to manage. Transforaminal endoscopy (TELD) has evolved to become an interesting alternative for lumbar disc herniations. The aim of the paper is to review our technique of transforaminal endoscopy in large central disc herniations and describe the clinical and radiographic results.

Full-Endoscopic Resection of Ligamentum Flavum Cyst in Lumbar Spine.

Background: Cysts of the ligamentum flavum (LF) are rare occurrences, with only a few cases reported in literature. They are a result of age-related degenerative changes in the LF. The cyst compresses the neural elements and causes neurogenic symptoms.
