Electrolytes for Sodium Ion Batteries: The Current Transition from Liquid to Solid and Hybrid systems.

Sodium-ion batteries (NIBs) have recently garnered significant interest in being employed alongside conventional lithium-ion batteries, particularly in applications where cost and sustainability are particularly relevant. The rapid progress in NIBs will undoubtedly expedite the commercialization process. In this regard, tailoring and designing electrolyte formulation is a top priority, as they profoundly influence the overall electrochemical performance and thermal, mechanical, and dimensional stability.

Sacral Neuromodulation: Device Improvement and Current Applications in Urology.

Sacral neuromodulation (SNM) offers a therapeutic approach to urological patients suffering from idiopathic overactive bladder (OAB) syndrome, with or without incontinence and non-obstructive urinary retention (NOR), who are not responding to or are not compliant with conservative or medical therapies. The exact mechanism of action of SNM is not fully understood but modulation of the spinal cord reflexes and brain networks by peripheral afferents is regarded as the main pathway. Over the years, surgical techniques improved, leading to the development of the modern two-stage implantation technique.

Love and frailty and an avalanche of missteps.

A retired oncologist describes the unexpected death of his wife, Claudia, who spent 25 years as head of the geriatrics service of a major VA hospital. The couple drew comfort in their orchestration of a "good death"; nevertheless they understood that her death was hastened by a number of missteps. In the 2 months following a hip fracture, a chain of complications that required five surgical interventions led to massive hemorrhage from necrotizing esophagitis.
