Sex differences in patient journeys to diagnosis, referral, and surgical treatment of trigeminal neuralgia: implications for equitable care.
Trigeminal neuralgia (TN) is an orofacial pain disorder that is more prevalent in females than males. Although an increasing number of studies point to sex differences in chronic pain, how sex impacts TN patients' journeys to care has not been previously addressed. This study sought to investigate sex differences in patients' journeys to diagnosis, referral, and treatment of TN within a large national context. ⋯ Critical sex differences in patients' journeys to TN surgical treatment were identified, with females enduring considerably longer referral timelines and expressing significantly greater pain intensity than males at referral. Taken together, our findings suggest the presence of unconscious bias and discrimination against females and highlight the need for expediting TN treatment referral for female TN patients.

Reduced time to imaging, length of stay, and hospital charges following implementation of a novel postoperative pathway for craniotomy.
The authors created a postoperative postanesthesia care unit (PACU) pathway to bypass routine intensive care unit (ICU) admissions of patients undergoing routine craniotomies, to improve ICU resource utilization and reduce overall hospital costs and lengths of stay while maintaining quality of care and patient satisfaction. In the present study, the authors evaluated this novel PACU-to-floor clinical pathway for a subset of patients undergoing craniotomy with a case time under 5 hours and blood loss under 500 ml. ⋯ The featured PACU-to-floor pathway reduces the stay of postoperative craniotomy patients and does not increase the risk of early hospital readmission.

Prediction of intracranial pressure crises after severe traumatic brain injury using machine learning algorithms.
Avoiding intracranial hypertension after traumatic brain injury (TBI) is a foundation of neurocritical care, to minimize secondary brain injury related to elevated intracranial pressure (ICP). However, this approach at best is reactive to episodes of intracranial hypertension, allowing for periods of elevated ICP before therapies can be initiated. Accurate prediction of ICP crises before they occur would permit clinicians to implement preventive strategies, minimize total time with ICP above threshold, and potentially avoid secondary injury. The objective of this study was to develop an algorithm capable of predicting the onset of ICP crises with sufficient lead time to enable application of preventative therapies. ⋯ The presented model can provide accurate and timely forecasts of ICP crises in patients with severe TBI 10-20 minutes prior to their occurrence. If validated and implemented in clinical workflows, this algorithm can enable earlier intervention for ICP crises, more effective treatment of intracranial hypertension, and potentially improved outcomes following severe TBI.

Correlation of callosal angle at the splenium with gait and cognition in normal pressure hydrocephalus.
Idiopathic normal pressure hydrocephalus (iNPH) is characterized by ventricular enlargement that deforms the corpus callosum, making the callosal angle (CA) small. The authors aimed to evaluate the clinical usefulness of the CA in different planes in iNPH. ⋯ The study results suggest that interhemispheric disconnections at the splenium are, at least in part, responsible for gait and cognitive disturbance in iNPH. The CA at the splenium is a unique morphological feature that correlates with gait and cognition in iNPH, and it is useful for discriminating iNPH from other neurological diseases and healthy controls.

Prefrontal association of subthalamic deep brain stimulation with rapid eye movement sleep behavior disorder in Parkinson's disease.
Subthalamic nucleus (STN)-deep brain stimulation (DBS) in Parkinson's disease (PD) patients affects not just focused target areas but also diffuse brain networks. The effect of this network modulation on nonmotor DBS effects is not fully understood. By concentrating on the sleep domain, the authors comprehensively determined the influence of electrode location and related structural/functional connections on changes in probable rapid eye movement (REM) sleep behavior disorder (pRBD) symptoms after STN-DBS, which has been reported to ameliorate, deteriorate, or remain constant. ⋯ Recovery of pRBD symptoms was predicted on the basis of the fibers connecting the STN electrode to prefrontal regions. These findings implied that the placement of STN-DBS leads influences the fibers to prefrontal regions and may be used to enhance treatment of pRBD symptoms; however, further prospective studies are needed to validate these findings.
