A perspective: neuraxial therapeutics in pain management: now and future.

The neuraxial delivery of drugs for the management of pain and other spinal pathologies is widely employed and is the subject of a large volume of ongoing research with several thousand papers appearing in the past 5 years alone on neuraxial delivery. Several learned texts have been recently published. A number of considerations have contributed to this widespread interest in the development of the use of neuraxial therapeutics to manage pain.

Pain perception while listening to thrash heavy metal vs relaxing music at a heavy metal festival - the CoPainHell study - a factorial randomized non-blinded crossover trial.

Objectives: Music festivals are often a source of joy, but also a risk of injury. While previous studies suggest music can relieve pain, its effect has not been tested in festival settings, nor has the effect of high-energy vs soothing music been compared. We hypothesized that guests at a heavy metal music festival would experience less pain when listening to thrash heavy metal compared to relaxing music, with the effect being influenced by music preference and increased with higher alcohol intake.

A Radiological Clip Design Using Ultrasound Identification to Improve Localization.

Objective: We demonstrate the use of ultrasound to receive an acoustic signal transmitted from a radiological clip designed from a custom circuit. This signal encodes an identification number and is localized and identified wirelessly by the ultrasound imaging system.

Methods: We designed and constructed the test platform with a Teensy 4.

An on-line SPE-LC-MS/MS method for quantification of nucleobases and nucleosides present in biological fluids.

Solid phase extraction (SPE) and liquid chromatographic (LC) separation of nucleobases and nucleosides are challenging due to the high hydrophilicity of these compounds. Herein we report a novel on-line SPE-LC-MS/MS method for their quantification after pre-column derivatization with chloroacetaldehyde (CAA). The method proposed is selective and sensitive with limits of detection at the nano-molar level.
