The motor unit: a chequered history
The Meryon Society has had two previous historical lectures on the motor unit. One by John Pearn from Brisbane in 2001[1] and another by Michael Swash in 2006 [2], both of which emphasised neural aspects of the motor unit. John Pearn spoke of the work of Swammerdam and the beginnings of experimentation on nerves, not just observation. Swammerdam challenged theories on how a nerve could make a muscle contract, beginning the ideas of the neuromuscular junction. Michael Swash also spoke on the historical aspects of innervation and the neuromuscular junction. (Source: Neuromuscular Disorders)

"Inherently Limited by Our Imaginations": Health Anxieties, Politics, and the History of the Climate Crisis
Perspect Biol Med. 2024;67(1):31-62. doi: 10.1353/pbm.2024.a919709.ABSTRACTAs global warming became a cause of concern in the 1980s, researchers and climate activists initially paid little attention to the possible health effects of a warmer world. This changed quickly between 1985 and 1989, when scientists working on contracts with the US Department of Energy and the Environmental Protection Agency extrapolated from existing knowledge about the impact of weather on health to speculate about how global warming would impact health. However, they downplayed the impact of their contributions by highlighting the uncertainty in...

Sensors, Vol. 24, Pages 2629: Identification of the Biomechanical Response of the Muscles That Contract the Most during Disfluencies in Stuttered Speech
. Elias
Stuttering, affecting approximately 1% of the global population, is a complex speech disorder significantly impacting individuals’ quality of life. Prior studies using electromyography (EMG) to examine orofacial muscle activity in stuttering have presented mixed results, highlighting the variability in neuromuscular responses during stuttering episodes. Fifty-five participants with stuttering and 30 individuals without stuttering, aged between 18 and 40, participated in the study. EMG signals from five facial and cervical muscles were recorded during speech tasks and analyzed for mean amplitude an...

Improving Safe Opioid Prescribing for Pediatric Hospice and Palliative Care Patients
1. Utilizing a quality improvement-approach, participants will self-report the ability to assess the implementation of several opioid safety components (i.e. opioid safety contract, open-ended question, and mental health screener) and how they may improve safety regarding opioid prescribing in pediatric hospice/palliative care patients.2. Utilizing a quality improvement-approach, participants will self-report the ability to learn skills relating to discussing safe opioid prescribing with pediatric hospice/palliative care patients and their families.

What's important in a contract beyond the salary? A primer for pain physicians and trainees
Pain Pract. 2024 Apr 16. doi: 10.1111/papr.13377. Online ahead of print.ABSTRACTThis manuscript is designed to complement the previously published primer on salary structures for new pain physicians. The previous manuscript "Employment Contract Financial Models for the Pain Physician: A Primer" had a goal of increasing understanding of financial models by pain fellows when preparing for contract negotiations. This manuscript illustrates the many equally important considerations of "non-monetary" values that are a significant part of contract negotiation outside of salary. It contributes to the overall education for trainee...

Microsurgical limb reconstruction in the non-concordant patient
Substance misuse is common in patients undergoing limb reconstruction secondary to open fractures and fracture related infection. This group risk breaching the social contract with their treating team through reduced engagement with perioperative care. Potential problems include limited social support, intravenous access, analgesia and withdrawal. These factors may negatively influence the range of treatments offered to this group.We aimed to establish the prevalence and outcomes of the problematically non-concordant cohort in our limb reconstruction population, who we aim to treat equitably even where non-concordance is s...

Pneumothorax during manned chamber operations: A summary of reported cases
Undersea Hyperb Med. 2024 First Quarter;51(1):29-35.ABSTRACTIn-chamber pneumothorax has complicated medically remote professional diving operations, submarine escape training, management of decompression illness, and hospital-based provision of hyperbaric oxygen therapy. Attempts to avoid thoracotomy by combination of high oxygen partial pressure breathing (the concept of inherent unsaturation) and greatly slowed rates of chamber decompression proved successful on several occasions. When this delicate balance designed to prevent the intrapleural gas volume from expanding faster than it contracts proved futile, chest drains...

Medical and surgical management of pneumothorax in diving and hyperbaric chambers
Undersea Hyperb Med. 2024 First Quarter;51(1):17-28.ABSTRACTThe presence of a pneumothorax within a pressurized chamber represents unique diagnostic and management challenges. This is particularly the case in the medical and geographic remoteness of many chamber locations. Upon commencing chamber decompression, unvented intrapleural air expands. If its initial volume and/or degree of chamber pressure reduction is significant enough, a tension pneumothorax will result. Numerous reports chronicle failure to diagnose and manage in-chamber pneumothorax with resultant morbidity and one fatal outcome. Such cases have occurred in...
