Introduction: Thoracolumbar kyphosis (TLK) is a frequently reported spinal deformity in achondroplasia, which in combination with the characteristic narrow spinal canal in achondroplasia predisposes for symptomatic spinal stenosis. There is however no consensus on the optimal treatment, due to limited data on diagnostic criteria, the natural development and the prevalence of TLK.

Research Question: This study aims to assess the prevalence, natural development, and diagnostic criteria for pathological TLK in individuals with achondroplasia.

Subgroup analyses are essential to generate new hypotheses or to estimate treatment effects in clinically meaningful subgroups of patients. They play an important role in taking the next step toward personalized surgical treatment for brain tumor patients. However, subgroup analyses must be used with consideration and care because they have significant potential risks.

Article Synopsis
  • The study aimed to create a new onco-functional outcome (OFO) classification for glioblastoma patients, combining the goals of complete tumor resection and avoiding functional loss into four categories.
  • Analyzing data from 858 patients over ten years, they found that the OFO classification significantly influenced overall survival (OS) and progression-free survival (PFS) rates, especially in certain tumor types.
  • The results showed that achieving the best outcome (OFO1) was linked to improved survival rates and higher likelihood of receiving additional therapy, particularly with awake craniotomy procedures being more effective in avoiding deficits.

Background: Alcohol use is associated with a wide spectrum of neurological disorders, including cognitive dysfunction and dementia. Likewise, the high prevalence of cognitive dysfunction and dementia specifies the urgent need to identify modifiable risk factors. Because findings on alcohol and cognitive dysfunction and dementia have been inconsistent, the present dose-response meta-analysis of cohort and case control studies was conducted to evaluate the available evidence.

Background Context: Currently, there is no universally accepted method for assessing radiological fusion shortly after anterior cervical discectomy. Five-year follow-up radiological X-rays demonstrating solid fusion or absence of fusion provided a gold standard for comparison with various assessment methods.

Purpose: Establishing the most accurate diagnostic test for earlier bony fusion assessment by comparing different cut-off values for the difference in interspinous distance and the change in Cobb angle on dynamic radiological images against the established gold standard.

Article Synopsis
  • The study examines the management of intracranial pressure in patients with moderate-to-severe traumatic brain injury (msTBI), specifically comparing the use of external ventricular drains (EVD) and intraparenchymal monitors (IPM).
  • Researchers analyzed data from 521 adult msTBI patients at two academic institutions to identify factors influencing the choice between EVD and IPM, as well as to assess the clinical outcomes for both groups.
  • Key findings indicate that while certain conditions like epidural hemorrhage and midline shift influenced the likelihood of receiving IPM, EVD patients generally required more intensive treatment, yet no significant differences were noted in overall patient outcomes between the two groups.
