ReviewAssessing Long-term Neurodevelopmental Outcome Following General Anesthesia in Early Childhood: Challenges and Opportunities.
Neurodegeneration has been reported in young animals after exposure to all commonly used general anesthetic agents. The brain may be particularly vulnerable to anesthetic toxicity during peak synaptogenesis (in gestation and infancy). Human studies of long-term neurodevelopmental outcome following general anesthesia in early childhood report contradictory findings. ⋯ We discuss potential solutions to these challenges. Further adequately powered, multicenter, prospective randomized controlled trials of anesthetic-induced neurotoxicity in children are required. However, we believe that the inherent methodological challenges of studying anesthetic-induced neurotoxicity necessitate the parallel use of well-designed observational cohort studies.

Systematic Review of the Efficacy and Safety of Gabapentin and Pregabalin for Pain in Children and Adolescents.
The barriers to opioid use in some countries necessitate the need to identify suitable alternatives or adjuncts for pain relief. The gabapentinoids (gabapentin and pregabalin) are approved for the management of persistent pain in adults, but not in children. Searches were conducted in Embase, Medline, Scopus, and Web of Science up until November 2017, for randomized controlled trials that investigated the analgesic effects of gabapentin or pregabalin in children and adolescents <18 years of age. ⋯ Two of the identified clinical trials (conducted by the same first author) on the efficacy of gabapentin for prophylactic postadenotonsillectomy pain relief were omitted from narrative synthesis due to clear evidence of fabricated data. Overall, this review identified a paucity of evidence for the analgesic effect and safety of gabapentinoids in children. We also suggest audit of any current evidence-based practice and clinical guidelines that have cited the research studies with fabricated data.

Progressive Increase in Scholarly Productivity of New American Board of Anesthesiology Diplomates From 2006 to 2016: A Bibliometric Analysis.
Improving research productivity is a common goal in academic anesthesiology. Initiatives to enhance scholarly productivity in anesthesiology were proposed more than a decade ago as a result of emphasis on clinical work. We hypothesized that American Board of Anesthesiology diplomates certified from 2006 to 2016 would be progressively more likely to have published at least once during this time period. ⋯ Publications by new diplomates of the American Board of Anesthesiology have increased between 2006 and 2016. Whether the observed increase in publications could reflect efforts to stimulate interest in academic objectives during training remains to be proven.

ReviewGlymphatic System Function in Relation to Anesthesia and Sleep States.
The brain is one of the most metabolically active organs in the body. The brain's high energy demand associated with wakefulness persists during rapid eye movement sleep, and even during non-rapid eye movement sleep, cerebral oxygen consumption is only reduced by 20%. The active bioenergetic state parallels metabolic waste production at a higher rate than in other organs, and the lack of lymphatic vasculature in brain parenchyma is therefore a conundrum. ⋯ Over the past 5 years, emerging data have begun to shed new light on these processes in the form of the "glymphatic system," a novel brain-wide perivascular transit passageway dedicated to CSF transport and metabolic waste drainage from the brain. Here, we review the key anatomical components and operational drivers of the brain's glymphatic system, with a focus on its unique functional dependence on the state of arousal and anesthetic regimens. We also discuss evidence for why clinical exploration of this novel system may in the future provide valuable insight into new strategies for preventing delirium and cognitive dysfunction in perioperative and critical care settings.
