Objective: Craniosynostosis is the premature fusion of the calvarial sutures and is associated with aesthetic impairment and secondary damage to brain growth. Associated neurological injuries can result from increased intracranial pressure (ICP) and abnormal cerebral blood flow (CBF). Arterial spin-labeling (ASL) MRI was used to assess regional CBF in developing rabbits with early-onset coronal suture synostosis (EOCS) and age-matched wild-type controls (WT).
Methods: Rabbits were subjected to ASL MRI at or near 10, 25, or 42 days of age. Differences in regional CBF were assessed using one-way ANOVA.
Conclusion: CBF was similar in WT and EOCS rabbits with the exception of the peridural surfaces in EOCS rabbits at 25 days of age. A twofold increase in peridural CBF at 25 days of age coincides with a transient increase in ICP. By 42 days of age, CBF in peridural surfaces had decreased.

Background: Total hip arthroplasty (THA) practices are evolving under the influence of the current value-based healthcare system and bundled payment models. This study aimed to (1) evaluate national trends in discharge disposition and postoperative outcomes after THA, (2) compare discharge cohorts on episode-of-care parameters, and (3) determine predictors of nonhome discharge from 2011 to 2021.
Methods: The National Surgical Quality Improvement Program database was queried for THA data from 2011 to 2021.

Background: Clozapine is effective for treatment-resistant schizophrenia and bipolar disorder but is often discontinued due to adverse effects. This study compared early clozapine discontinuation rates and reasons in patients with mood and psychotic disorders.
Methods: Data from all individuals with mood or psychotic disorders who initiated clozapine for the first time at the inpatient psychiatric unit of Mayo Clinic, Rochester, Minnesota, between 2014 and 2022 were retrospectively analyzed.

Importance: The impact of adjunctive intra-arterial tenecteplase administration following near-complete to complete reperfusion by endovascular thrombectomy (EVT) for acute ischemic stroke is unknown.
Objective: To assess the efficacy and adverse events of adjunctive intra-arterial tenecteplase in patients with large vessel occlusion stroke who had achieved near-complete to complete reperfusion (defined as a score on the expanded Thrombolysis in Cerebral Infarction [eTICI] scale of 2c to 3) after EVT.
Design, Setting, And Participants: Investigator-initiated, randomized, open-label, blinded outcome assessment trial implemented at 34 hospitals in China among 540 patients with stroke due to proximal intracranial large vessel occlusion within 24 hours of the time they were last known to be well, with an eTICI score of 2c to 3 after EVT, and without prior intravenous thrombolysis.

Importance: Persisting or new thrombi in the distal arteries and the microcirculation have been reported to limit the benefits of successful endovascular thrombectomy for patients with acute ischemic stroke. It remains uncertain whether intra-arterial thrombolysis by urokinase following near-complete to complete reperfusion by thrombectomy improves outcomes among patients with ischemic stroke due to large vessel occlusion.
Objective: To assess the efficacy and adverse events of intra-arterial urokinase after near-complete to complete reperfusion by thrombectomy for acute ischemic stroke due to large vessel occlusion.
