Review Meta Analysis
Heart rate variability as a predictor of mortality in traumatic brain injury: a systematic review and meta-analysis.
To systematically review the medical literature to determine the utility of heart rate variability in predicting mortality for moderate to severe traumatic brain injury. ⋯ This meta-analysis predicted high mortality based on odds ratio for variables low-frequency/high-frequency ratio, high-frequency peak, and TP. However, the statistical analysis was weakened owing to the high level of heterogeneity in the included studies. Further research is needed to generate high-quality recommendations regarding heart rate variability as a predictor of mortality after traumatic brain injury.

Review Meta Analysis
Treatment Outcomes of Intracranial Myeloid Sarcomas: A Meta-Analysis.
Intracranial myeloid sarcomas (IMS) are rare central nervous system manifestations of malignant hematopoietic neoplasms of myeloid origin such as acute myeloid leukemia and chronic myeloid leukemia. Reported cases in the literature are limited to primarily case reports. We present a systematic review of this rare central nervous system tumor, characterizing the clinical presentation, tumor location, histopathology, and available treatment modalities. We correlate these variables with mortality, recurrence, and complications to suggest optimal management strategies for IMS. ⋯ The use of adjuvant radiotherapy or chemotherapy for IMS significantly reduces mortality, confirming IMS as a cranial manifestation of a systemic disease. Although surgical treatment is indicated for histopathologic diagnosis and to relieve mass effect, the extent of resection does not predict overall survival.

Multicenter Study
Time to surgery for unstable thoracolumbar fractures in Latin America- a multicentric study.
We sought to identify delays for surgery to stabilize unstable thoracolumbar fractures and the main reasons for them across Latin America. ⋯ Timing for surgery in this sample of unstable fractures was over 72 hours in more than half of the sample and longer than a week in about a quarter. The main reasons for this delay were clinical instability and lack of economic resources. There is an apparent need for increased funding for the treatment of spinal trauma patients in Latin America.

To describe the traumatic brain injury (TBI) care in the city of Coari, Amazonas, from 2017-2019. ⋯ The profile of patients affected by TBI in the city of Coari was characterized by male victims of motorcycle accidents with age between 20 and 29 years. The high transfer rates indicates the need for a better neurotrauma assistance. Further investigations and studies associated with regional specificities are essential to recommend changes on the scope of public health and therefore decrease the incidence of TBI.

Because of involvement of the optic apparatus, craniopharyngiomas frequently present with visual deterioration. Although visual improvement is a primary goal of surgical intervention, prediction models are lacking. ⋯ Patients with reduced preoperative vision, specific radiographic vascular involvement, and gross total resection showed increased odds of visual improvement, whereas the translaminar approach was associated with visual deterioration. Such characteristics may facilitate patient-surgeon counseling and surgical decision making.
