CONCLUSIONS: Currently, several microleakage assessment techniques are being used, with the dye method being the most reported one. Several variations in the experimental protocols exist, which make it difficult to compare the results. The use of dyes and nuclear medicine methods is sensitive and can be used to evaluate microleakage.

This note reflects on the accomplishments and teachings of Bernie Maskit. Bernie was an expert problem solver, an incredible teacher, and a person who built bridges to faraway lands that connected different people, cultures, and ideas.

Excessive Wnt signaling contributes to the development of fibrotic diseases and cancer. Here, we report the findings of a phase 1 study evaluating AZD5055, an orally administered porcupine inhibitor, which inhibits Wnt signaling. The primary objective was to evaluate the safety and tolerability of AZD5055 in healthy volunteers. Secondary and exploratory objectives were the pharmacokinetics and pharmacodynamics of AZD5055, respectively. Sixty healthy volunteers were randomized to receive placebo...

BackgroundThe effectiveness of endovascular thrombectomy (EVT) for low Alberta Stroke Program Early CT score (ASPECTS) stroke patients with occlusion of the second segment of the middle cerebral artery (M2) is unclear.MethodsThis was a multicenter retrospective study. Patients with M1 or M2 occlusions and low ASPECTS (<6) who underwent successful EVT (modified treatment in cerebral ischemia score of 2b or higher) were included. Primary outcome was futile EVT reperfusion (defined as 90-day...

Energy storage technologies such as lithium-ion batteries (LIBs) incorporate carbon components key to their function. Graphite and carbon binder components in LIB electrodes are engineered to deliver critical electrical and mechanical properties, as are the surface chemistry and morphology of carbon blacks (CBs) in LIBs and catalysts. The challenge of relating surface chemistry to morphology is complicated by the numerous forms of carbon bonding and potential for surface functional groups....

Despite advances in the management of traumatic brain injury (TBI) in the intensive care unit (ICU), and the implementation of new diagnostic techniques and monitoring modalities, the rate of poor neurological outcomes remains high. Specialized neurocritical care units have been shown to improve outcomes. Guidelines have been developed, but most recommendations are based on low levels of evidence. This has led to substantial heterogeneity in clinical practice for many aspects of TBI management,...

Full endoscopic spine surgery (FESS) offers an ultra-minimally invasive solution for addressing many different degenerative spine pathologies. While FESS has demonstrated strong evidence for faster recovery, reduced hospital stays, fewer complications, and potentially lower overall costs, FESS remains underutilized in low-income countries (LICs). This narrative review synthesizes the existing literature to evaluate access to FESS in LICs, highlighting challenges such as a lack of trained...

CONCLUSION: We anticipate that comprehensive phenotyping will greatly facilitate the identification of phenotype-specific transcriptional signatures associated with chronic neck and low back pain, revealing new neurobiological and/or neuro-immunological mechanisms of painful diseases.

CONCLUSIONS: Participants who were reached by the digital outreach intervention codeveloped and disseminated to patients from low-SES communities were more likely to complete LCS.

CONCLUSIONS: Standardizing QA parameters via injection bias correction improves occlusion prediction accuracy for flow diverter-treated IAs. Adding explainable AI (eg, LIME) clarifies model decisions, demonstrating the feasibility of clinically interpretable AI-based outcome prediction.

Traumatic brain injury (TBI) is frequently associated with acute and chronic disturbances in sleep architecture. However, the extent to which injury severity and biological sex influence post-traumatic sleep patterns remains underexplored in preclinical models. Here, we used a validated, noninvasive piezoelectric monitoring system to assess sleep in male and female mice following sham (n = 30), mild (n = 32), or moderate (n = 32) midline fluid percussion injury (mFPI). Physiological parameters...

CONCLUSION: PECF under local anesthesia in the lateral decubitus position provides comparably effective pain relief and functional improvement comparable to general anesthesia, though the difference in complication rates was not statistically significant and requires larger studies for confirmation. This technique may be particularly advantageous for patients at higher risk for anesthesia-related complications. Further research is warranted to validate these findings in larger, prospective...

CONCLUSIONS: TIB was well-tolerated in pediatric patients with relapsed medulloblastoma, and outcomes were similar to those published in clinical trials. TIB therapy should be considered for patients with relapsed medulloblastoma, especially patients with limited access to care due to travel barriers.

CONCLUSION: In patients with sICH after AIS after MT, those selected for DC had less favorable outcomes and similar rates of mortality at 90 days.

Study DesignReview of the literature with critical appraisal and clinical recommendations.ObjectiveTo highlight contemporary concepts relating to surgical care for acute traumatic spinal cord injury (SCI) based on recent evidence that may be integrated into clinical practice.MethodsThree recent articles relating to the surgical management of acute traumatic SCI were selected and critically appraised. Clinical practice recommendations were developed and graded as strong or...

CONCLUSIONS: SRS was associated with increased symptomatic and mRS Score improvement for low-grade dAVFs compared with conservative management. SRS had a low complication risk and did not appear to alter dAVF obliteration or haemorrhage. Future prospective trials on SRS as a first-line intervention for symptomatic low-grade dAVFs should be considered.

Accurately capturing the temporal distribution of polysomnographic sleep stages is critical for the study of sleep function, regulation, and disorders in higher vertebrates. In laboratory rodents, scoring of electrocorticography (ECoG) and electromyography (EMG) recordings is usually performed manually by categorizing 5- to 10-sec epochs as 1 of 3 specific stages: wakefulness, rapid-eye-movement (REM) sleep, and non-REM (NREM) sleep. This process is laborious, time-consuming, and particularly...

Attenuated whole organism vaccines targeting the malaria liver stage reliably confer sterile immunity. These vaccines completely protect female mice from infection, but protection in male mice remains unproven. We discover that male mice vaccinated with prime-and-trap, a whole organism-based vaccine strategy, exhibit poorer protection against Plasmodium sporozoite challenge than females. We investigate this sex difference, and identify vaccinated males have fewer hepatic memory CD8^(+) T cells...
