Neurosurg Rev 2024; 47:106. [PMID: 38453788 DOI: 10.1007/s10143-024-02350-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2024] [Revised: 03/02/2024] [Accepted: 03/06/2024] [Indexed: 03/09/2024]
Abstract
This retrospective cohort study aimed to investigate the impact of low fibrinogen levels on in-hospital mortality and 6-month functional outcomes in patients with traumatic brain injury (TBI) within a single center,focusing on the strengths, weaknesses, and suggestions for future research. Patients were followed up to assess in-hospital mortality and functional outcomes at six months post-injury using standardized scales. Statistical analyses, including multivariable regression models, were employed to evaluate the association between low fibrinogen levels and outcomes, adjusting for potential confounders, and revealed a significant association between low fibrinogen levels and increased in-hospital mortality rates among patients with TBI (p < 0.05). Additionally, patients with low fibrinogen levels exhibited poorer functional outcomes at the 6-month follow-up, as evidenced by lower scores on functional assessment scales than those with normal fibrinogen levels, suggesting that low fibrinogen levels upon admission may serve as a prognostic indicator for adverse outcomes in patients with TBI, including higher in-hospital mortality rates and impaired functional recovery at 6 months post-injury. Furthermore, this study explored conservative and surgical management approaches, offering valuable insights into treatment decision-making and outcomes. Future research should prioritize prospective, multicenter studies with standardized protocols, collaborative efforts among institutions, and innovative techniques to advance our understanding and management.

Abstract
In patients affected by traumatic brain injury (TBI), hypofibrinogenemia within the initial hours of trauma can be expected due to vascular and inflammatory changes. In this study, we aimed to evaluate the effect of hypofibrinogenemia on the in-hospital mortality and 6-month functional outcomes of TBI patients, admitted to Rajaee Hospital, a referral trauma center in Shiraz, Iran. This study included all TBI patients admitted to our center who had no prior history of coagulopathy or any systemic disease, were alive on arrival, and had not received any blood product before admission. On admission, hospitalization, imaging, and 6-month follow-up information of included patients were extracted from the TBI registry database. The baseline characteristics of patients with fibrinogen levels of less than 150 mg/dL were compared with the cases with higher levels. To assess the effect of low fibrinogen levels on in-hospital mortality, a uni- and multivariate was conducted between those who died in hospital and survivors. Based on the 6-month GOSE score of patients, those with GOSE < 4 (unfavorable outcome) were compared with those with a favorable outcome. A total of 3049 patients (84.3% male, 15.7% female), with a mean age of 39.25 ± 18.87, met the eligibility criteria of this study. 494 patients had fibrinogen levels < 150 mg/dl, who were mostly younger and had lower average GCS scores in comparison to cases with higher fibrinogen levels. By comparison of the patients who died during hospitalization and survivors, it was shown that fibrinogen < 150 mg/dl is among the prognostic factors for in-hospital mortality (OR:1.75, CI: 1.32:2.34, P-value < 0.001), while the comparison between patients with the favorable and unfavorable functional outcome at 6-month follow-up, was not in favor of prognostic effect of low fibrinogen level (OR: 0.80, CI: 0.58: 1.11, P-value: 0.19). Hypofibrinogenemia is associated with in-hospital mortality of TBI patients, along with known factors such as higher age and lower initial GCS score. However, it is not among the prognostic factors of midterm functional outcome.

Abstract
BACKGROUND While firearms projectile injuries to the head carry a high rate of morbidity and mortality, current literature in clinical management remains controversial. Decompressive hemicraniectomy (DHC) has been previously described in the neurosurgical literature for traumatic brain injuries, with positive results in the reduction of mortality. Here we aim to assess DHC as a damage control approach for multilobar firearm injuries to the head and compare our results with what is present in the literature. METHODS A retrospective review of patients who sustained multilobar firearm injuries to the head admitted to our center from January 2009 to April 2021 was performed. Exclusion criteria were a Glasgow Coma Scale (GCS) score <5, and/or brain stem dysfunction that persisted despite stabilization and medical therapy for intracranial hypertension. RESULTS A total of 20 patients were analyzed, with an average GCS on admission of 8.35. The 60-day mortality rate for all 20 patients was 20% with a total of 4 deaths, 1 of which was due to pulmonary sepsis in the critical postoperative care unit. The mean hospital stay of surviving patients was 22 days. CONCLUSIONS DHC should be considered as a damage control strategy for young patients with multilobar firearm injuries and GCS >5, having yielded favorable results in this study when compared to current literature.

Abstract
Background The aim of this study was to report the demographics and clinical features of patients with penetrating traumatic brain injury (PTBI) during the past 5 years in Rajaee Hospital, a tertiary referral trauma center in Shiraz, southern Iran. Methods We conducted a 5-year retrospective evaluation of all patients diagnosed with PTBI who were referred to Rajaee Hospital. We retrieved the following items from the hospital's database and PACS system: patients' demographics, on-admission Glasgow Coma Scale (GCS), presence of trauma to other organs, duration of the hospital and ICU stay, the neurosurgical interventions, any necessity of tracheostomy, duration of ventilator dependency, the entrance point of the trauma in the skull, type of assault, length of trajectory in the brain parenchyma, the number of remaining objects in the brain, the occurrence of any hemorrhagic phenomenon, the cross of the bullet from the midline or coronal suture, and the presence of the pneumocephalus. Results A total of 59 patients with a mean age of 28.75 ± 9.40 had PTBI over the 5 years. The mortality rate was 8.5%. Stab wounds, shotguns, gunshots, and airguns were the cause of injury in 33 (56%), 14 (23.7%), 10 (17%), and 2 (3.4%) patients, respectively. The median initial GCS of patients was 15 (3-15). Intracranial hemorrhage was observed in 33 cases, subdural hematoma in 18 cases, intraventricular hemorrhage in eight cases, and subarachnoid hemorrhage in four cases. The mean duration of hospitalization was 10.05 ± 10.75 (ranging from 1 to 62 days). Furthermore, 43 patients experienced ICU admission with mean days of 6.5 ± 5.62 (1-23). The temporal and frontal regions were the most common entrance points, in 23 and 19 patients, respectively. Conclusion The incidence of PTBI is relatively low in our center, possibly due to the prohibition of possession or using warm weapons in Iran. Further, multicenter studies with larger sample sizes are needed to determine prognostic factors associated with worse clinical outcomes after PTBI.

Abstract
IntroductionIn order to obtain FDA Marketing Authorization for aid in the diagnosis of concussion, an eye tracking study in an intended use population was conducted.MethodsPotentially concussed subjects recruited in emergency department and concussion clinic settings prospectively underwent eye tracking and a subset of the Sport Concussion Assessment Tool 3 at 6 sites. The results of an eye tracking-based classifier model were then validated against a pre-specified algorithm with a cutoff for concussed vs. non-concussed. The sensitivity and specificity of eye tracking were calculated after plotting of the receiver operating characteristic curve and calculation of the AUC (area under curve).ResultsWhen concussion is defined by SCAT3 subsets, the sensitivity and specificity of an eye tracking algorithm was 80.4 and 66.1%, The AUC was 0.718. The misclassification rate (n = 282) was 31.6%.ConclusionA pre-specified algorithm and cutoff for diagnosis of concussion vs. non-concussion has a sensitivity and specificity that is useful as a baseline-free aid in diagnosis of concussion. Eye tracking has potential to serve as an objective “gold-standard” for detection of neurophysiologic disruption due to brain injury.
