To assess factors affecting the cumulative lifespan of a transplanted liver. ⋯ In summary, transplanted livers frequently get as old as those in the average population despite ischemic-reperfusion-injury and immunosuppression. The presented results justify using older donor livers regardless of donation type, even in sicker recipients with limited options.

Extensive audio-motor training and psychological stress can cause professional musicians acute overstrain-injury and chronic pain, resulting in damaged careers and diminished quality of life. It has also been previously shown that musicians might perceive pain differently than non-musicians. Therefore, the aim of our study was to quantify differences between musicians and non-musicians regarding their subjective responses to painful contact heat stimuli and assess how emotional traits might influence these responses. ⋯ The findings of this report justify musicians' repetitive sensorimotor training as an important model for plasticity and contribute to a better understanding of pain perception in musicians.

Opioid analgesics are commonly used to treat acute and chronic pain following traumatic injury. Psychiatric comorbidity has been reported to be associated with increased pain and persistent opioid use. Our aims were to determine the extent of post-injury opioid use and assess whether pre-injury antidepressant, benzodiazepine, and z-hypnotic drug use is associated with increased post-injury opioid use. ⋯ This large registry-based study adds to the body of knowledge on opioid use beyond in-hospital care in patients having sustained traumatic injury, a field which is scarcely investigated and not yet fully understood. It suggests that both previous drug therapy and the nature of opioid treatment initiation may affect outcome. This will help guide clinicians in selecting the appropriate pain management in this patient group.

Repetitive ischemia with reperfusion (I/R) injury is a common cause of myalgia. Ischemia with reperfusion injuries occur in many conditions that differentially affect males and females including complex regional pain syndrome and fibromyalgia. Our preclinical studies have indicated that primary afferent sensitization and behavioral hypersensitivity caused by I/R injury may be due to sex-specific gene expression in the dorsal root ganglia (DRG) and distinct upregulation of growth factors and cytokines in the affected muscles. ⋯ AUF1 knockdown was able to specifically inhibit repeated I/R-induced gene expression in females potentially downstream of prolactin receptor signaling. Data suggest RNA-binding proteins such as pAUF1 may underlie the sex-specific effects on DRG gene expression that modulates behavioral hypersensitivity after repeated I/R injury through prolactin signaling. This study may aid in finding distinct receptor differences related to the evolution of acute to chronic ischemic muscle pain development between sexes.

Medical Malpractice in Neurosurgery: An Analysis of Claims in the Netherlands.
Studying malpractice claims is important to improve quality of health care and patient safety and to educate the individual healthcare providers. The objective of this study was to describe characteristics of neurosurgical claims in the Netherlands. ⋯ Neurosurgery-related malpractice claims primarily involved spinal pathology and were mostly related to alleged treatment errors. Most claims did not result in compensation because there seemed to be no liability or culpable injury. However, the annual risk for a claim for Dutch neurosurgeons is considerable.
