Postextubation respiratory support treatment approaches, indications, and subgroups of patients with different responses to those therapies are rapidly changing. Planning optimal therapy in terms of choosing devices, timing of application and selecting settings with the goal of minimizing extubation failure is becoming a challenge. This review aims to analyze all the available evidence from a clinical point of view, trying to facilitate decision making at the bedside. ⋯ Planning postextubatin respiratory support must consider the risk for failing and the presence of some clinical conditions favoring noninvasive ventilation.Extubation can be safely accelerated by modifying screening criteria and spontaneous breathing trial settings, but there is room to increase the role of postextubation noninvasive respiratory support for this indication, always keeping in mind the dangers of delaying a needed intubation.

The future of global neurosurgery should focus on addressing the unmet neurosurgical need from a health system approach should we hope to achieve sustainable and ethical change. In this article, we review the global building blocks, as defined by the World Health Organization, and use this framework to propose strategies to strengthen neurosurgical care on the global frontier. The targets for Universal Healthcare Coverage by 2030, as outlined by the United Nations Sustainable Development Goals, are reviewed, and the role of neurosurgeons in addressing the global targets is discussed. ⋯ The execution of these global targets and indicators within the context of health system strengthening will be a persistent challenge, given the complexity of health system and its components. The neurosurgical community must continue to support, promote, and diversify collaborations, especially among deserts of neurosurgical care across the world. Innovative technology and education are essential to this global dilemma.

Compared with the modified Frailty Index-11 (mFI-11) frailty tool, reflective of patient comorbidities, the Fried phenotype weighs functional patient variables. This study examined using the Fried phenotype in predicting postoperative outcomes in craniotomy for patients with tumor. ⋯ The Fried phenotype more accurately correlates with postoperative outcomes including LOS, discharge disposition location, and complications than does the mFI-11 score. These findings can be used to guide preoperative planning, inform consent, and potentially identify patients who may benefit from functional optimization in the preoperative period to improve postoperative outcomes.

Na v 1.9 is of interest to the pain community for a number of reasons, including the human mutations in the gene encoding Na v 1.9, SCN11a , that are associated with both pain and loss of pain phenotypes. However, because much of what we know about the biophysical properties of Na v 1.9 has been learned through the study of rodent sensory neurons, and there is only 76% identity between human and rodent homologs of SCN11a , there is reason to suggest that there may be differences in the biophysical properties of the channels in human and rodent sensory neurons, and consequently, the contribution of these channels to the control of sensory neuron excitability, if not pain. Thus, the purpose of this study was to characterize Na v 1.9 currents in human sensory neurons and compare the properties of these currents with those in rat sensory neurons recorded under identical conditions. ⋯ However, we noted a number of potentially important differences between the currents in human and rat sensory neurons including a lower threshold for activation, higher threshold for inactivation, slower deactivation, and faster recovery from slow inactivation. Human Na v 1.9 was inhibited by inflammatory mediators, whereas rat Na v 1.9 was potentiated. Our results may have implications for the role of Na v 1.9 in sensory, if not nociceptive signaling.

Chronic pain is a pervasive and debilitating condition with increasing implications for public health, affecting millions of individuals worldwide. Despite its high prevalence, the underlying neural mechanisms and pathophysiology remain only partly understood. Since its introduction 35 years ago, brain diffusion magnetic resonance imaging (MRI) has emerged as a powerful tool to investigate changes in white matter microstructure and connectivity associated with chronic pain. ⋯ We conclude by highlighting emerging approaches and prospective avenues in the field that may provide new insights into the pathophysiology of chronic pain and potential new therapeutic targets. Because of the limited current body of research and unidentified targeted therapeutic strategies, we are forced to conclude that further research is required. However, we believe that brain diffusion MRI presents a promising opportunity for enhancing our understanding of chronic pain and improving clinical outcomes.
