Excess Opioid Medication and Variation in Prescribing Patterns Following Common Breast Plastic Surgeries.

Excess opioid prescribing has societal impacts including addiction, dependence, and misuse. This study aims to investigate prescribing patterns and self-reported patient experiences with opioid use, pain control, and disposal of unused medication following common breast surgeries. A total of 46 patients undergoing 5 breast procedures were identified during a predefined 14-week period.

Palytoxin evokes reversible spreading depolarization in the locust CNS.

Spreading depolarization (SD) describes the near-complete depolarization of central nervous system (CNS) neural cells as a consequence of chemical, electrical, or metabolic perturbations. It is well established as the central mechanism underlying insect coma and various mammalian neurological dysfunctions. Despite significant progress in our understanding, the question remains: which cation channel, if any, generates SD in the CNS? Previously, we speculated that the sodium-potassium ATPase (NKA) might function as a large-conductance ion channel to initiate SD in insects, potentially mediated by a palytoxin (PLTX)-like endogenous activator.

Transcriptional repression by HDAC3 mediates T cell exclusion from mutant lung tumors.

Histone Deacetylase 3 (HDAC3) function in vivo is nuanced and directed in a tissue-specific fashion. The importance of HDAC3 in mutant lung tumors has recently been identified, but HDAC3 function in this context remains to be fully elucidated. Here, we identified HDAC3 as a lung tumor cell-intrinsic transcriptional regulator of the tumor immune microenvironment.

History at the heart of medicine.

With a focus on the challenges of today and tomorrow in the critical medical humanities the role of history is often overlooked. Yet history and medicine are closely intertwined. Right now, with the surfacing of knotty problems such as changing demographics, chronic pain, loneliness and Long Covid - and the consequent necessity to change directions and policies - history seems more urgent than ever.

Interframe-tunable ultrafast differential-displacement holography.

We describe the details of a digital holographic microscopy diagnostic capable of quantifying both the topography and velocity of a km/s object with adjustable temporal sensitivity. This technique involves spatially multiplexing a double pulse reflected from a target with reference beams of precisely known temporal separation.
