Linear Scalp Incision in Brain Tumor Surgery: Intraoperative and Postoperative Considerations.

Background: Although the linear scalp incision is commonly used in neurosurgical practice, a systematic study elucidating its pros and cons in a specific surgical setting is lacking. Herein, we analyzed our experience with linear scalp incision in brain tumor surgery and the impact on intraoperative variables and postoperative complications.

Methods: Patients undergoing brain tumor surgery (January 2014-December 2021) at 2 neurosurgical departments were included and divided into 2 groups: linear or flap scalp incision.

Intracranial Meningiomas in Patients Aged ≥80 Years: Pathological Features and Surgical Problems.

Background: Patients aged >80 years frequently have intracranial meningiomas. In the present study, we have discussed the pathological features, comorbidities, and surgical complications for this age group from a surgical series and literature review.

Methods: In the present study, we reviewed a surgical series of 354 intracranial meningiomas and compared the oldest age group (age, ≥80 years) of 17 patients with 73 patients aged 70-79 years and 264 patients aged <70 years.

Acute sleep deprivation disrupts emotion, cognition, inflammation, and cortisol in young healthy adults.

Chronic sleep deprivation has been demonstrated to diminish cognitive performance, alter mood states, and concomitantly dysregulate inflammation and stress hormones. At present, however, there is little understanding of how an acute sleep deprivation may collectively affect these factors and alter functioning. The present study aimed to determine the extent to which 24-h of sleep deprivation influences inflammatory cytokines, stress hormones, cognitive processing across domains, and emotion states.

Molecular alterations in the integrated diagnosis of pediatric glial and glioneuronal tumors: A single center experience.

Objectives: Tumors of the central nervous system (CNS) are the most common pediatric solid tumors, where low grade (LGG) and high grade gliomas (HGG) represent up to 55% of CNS tumors. Current molecular classification of these tumors results in a more accurate diagnosis and risk stratification, which ultimately enables individualized treatment strategies. Identifying known alterations is a suitable approach, particularly in developing countries, where NGS approaches are not easily accessible.

Comprehensive Evolutionary Analysis of Complete Epstein-Barr Virus Genomes from Argentina and Other Geographies.

The sequence variability of the Epstein-Barr virus has been extensively studied throughout previous years in isolates from various geographic regions and consequent variations at both genetic and genomic levels have been described. However, isolates from South America were underrepresented in these studies. Here, we sequenced 15 complete EBV genomes that we analyzed together with publicly available raw NGS data for 199 EBV isolates from other parts of the globe by means of a custom-built bioinformatic pipeline.
