This was a prospective longitudinal hospital-based study involving consecutive patients diagnosed with ATSCI and managed at the National Hospital, Abuja. Sixty-five participants met the inclusion criteria. Each patient was resuscitated along the Advanced Trauma Life Support protocol, followed by history, neurological examination according to the International Standards for the Neurological Classification of Spinal Cord Injury (ISNCSCI), and AIS grades that were recorded. Magnetic resonance imaging scan of the injured spinal cord was done, and BASIC scores were assigned. Further management was as per the standard. Three months after injury, neurological examination was again carried out based on ISNCSCI and AIS grades assigned. Data were collected, analyzed, and correlated using Excel and SPSS version 23. Means, medians, correlation coefficients, and Fisher's exact <i>t</i>-tests were determined. <i>p</i>-Value <0.05 was considered statistically significant. Results show mean age was 39.1 ± 12.3 years. The majority (81.5%) were males, whereas 18.5% were females. The majority (67.7%) were skilled professionals, 13.8% were unskilled, and 18.5% were students. Most injuries (90.8%) were due to road traffic accidents, whereas 9.2% were due to falls. Majority (72.3%) of the patients had complete SCI (AIS grade A), whereas AIS grade E accounted for the least number (3.1%). Cervical spine injury affected 92.3% of patients, whereas 7.7% had thoracic spine injury. Most patients had BASIC 4 pattern on MRI (44.6%), whereas BASIC 1 pattern was the fewest (3.1%). Surgery was not done for 58.5% of patients, whereas 41.5% had surgical decompression and spine fusion. At 3 months postinjury, 15.4% of patients had AIS grade improvement, whereas 84.6% maintained their AIS grade. The largest AIS grade improvement was from grade B to C (6.2%), which was statistically significant (<i>p</i> = 0.04). BASIC score correlated moderately with admission AIS grade (<i>p</i> = 0.532). BASIC score also correlated moderately with AIS grade at 3 months postinjury (<i>p</i> = 0.546). BASIC score 4 was best at predicting poor outcome in ATSCI. In conclusion, BASIC score has a moderate correlation with AIS grade in ATSCI and can predict poor outcomes in ATSCI. BASIC score of 4 has the best discriminant value in prognosticating and represents severe SCI.</p>","PeriodicalId":74300,"journal":{"name":"Neurotrauma reports","volume":"5 1","pages":"592-605"},"PeriodicalIF":1.8,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11271144/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141790180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although it may be treated with anticoagulation, the decision to treat tCVST is nuanced by the risk of new or worsening hemorrhage. Presently, there are no guidelines on the investigation and management of tCVST. Therefore, we conducted a UK- and Ireland-wide practice variation survey. A 17-question survey was sent via Google Forms to neurosurgeons and intensive care doctors of at least ST3 (registrar) level and above in the UK and Ireland and distributed by the Society of British Neurological Surgeons and investigators of the Sugar or Salt trial between May 9, 2023, and September 15, 2023. Data were extracted from the survey for both qualitative and quantitative analyses. There were 41 respondents to the survey, 18 (43.9%) of whom were consultant neurosurgeons. Fifty-four percent of the respondents performed a computed tomography intracranial venogram to investigate for tCVST where there was a skull fracture overlying or adjacent to a venous sinus, whereas 43.9% performed these at the time of TBI diagnosis. Around three-fourth of the respondents anticoagulate for tCVST, largely within 3 days post-TBI. A range of hemorrhagic and thrombotic complications have been observed following decisions to treat and withhold treatment of tCVST, respectively. Around two-third of the respondents conducted follow-up imaging in confirmed tCVST. None of the respondents had an established departmental protocol for the management of tCVST. This UK- and Ireland-wide survey on the management of tCVST revealed a variation in its diagnosis, treatment, and follow-up with no departmental protocol established.

Therefore, we conducted a systematic review of the literature for all studies presenting a quantifiable statistical association between a continuous measure of cerebrovascular pressure reactivity and ICP in a human TBI cohort. The methodology described in the Cochrane Handbook for Systematic Reviews was used. BIOSIS, Cochrane Library, EMBASE, Global Health, MEDLINE, and SCOPUS were all searched from their inceptions to March of 2023 for relevant articles. Full-length original works with a sample size of ≥10 patients with moderate/severe TBI were included in this review. Data were reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. A total of 16 articles were included in this review. Studies varied in population characteristics and statistical tests used. Five studies looked at transcranial Doppler-based indices and 13 looked at ICP-based indices.

Based on the findings of this review, impaired reactivity seems to be associated with elevated ICP and reduced ICP waveform complexity.
