- Early Tracheostomy in Severe Traumatic Brain Injury Patients: A Meta-Analysis and Comparison With Late Tracheostomy(2020) FRANCA, Sabrina Araujo de; TAVARES, Wagner M.; SALINET, Angela S. M.; PAIVA, Wellingson S.; TEIXEIRA, Manoel J.Objectives: To elucidate the impact of early tracheostomy on hospitalization outcomes in patients with traumatic brain injury. Data Sources: Lilacs, PubMed, and Cochrane databases were searched. The close-out date was August 8, 2018. Study Selection: Studies written in English, French, Spanish, or Portuguese with traumatic brain injury as the base trauma, clearly formulated question, patient's admission assessment, minimum follow-up during hospital stay, and minimum of two in-hospital outcomes were selected. Retrospective studies, prospective analyses, and case series were included. Studies without full reports or abstract, commentaries, editorials, and reviews were excluded. Data Extraction: The study design, year, patient's demographics, mean time between admission and tracheostomy, neurologic assessment at admission, confirmed ventilator-assisted pneumonia, median ICU stay, median hospital stay, mortality rates, and ICU and hospital costs were extracted. Data Synthesis: A total of 4,219 studies were retrieved and screened. Eight studies were selected for the systematic review; of these, seven were eligible for the meta-analysis. Comparative analyses were performed between the early tracheostomy and late tracheostomy groups. Mean time for early tracheostomy and late tracheostomy procedures was 5.59 days (sd, 0.34 d) and 11.8 days (sd, 0.81 d), respectively. Meta-analysis revealed that early tracheostomy was associated with shorter mechanical ventilation duration (-4.15 [95% CI, -6.30 to -1.99]) as well as ICU (-5.87 d [95% CI, -8.74 to -3.00 d]) and hospital (-6.68 d [95% CI, -8.03 to -5.32 d]) stay durations when compared with late tracheostomy. Early tracheostomy presented less risk difference for ventilator-associated pneumonia (risk difference, 0.78; 95% CI, 0.70-0.88). No statistical difference in mortality was found between the groups. Conclusions: The findings from this meta-analysis suggest that early tracheostomy in severe traumatic brain injury patients contributes to a lower exposure to secondary insults and nosocomial adverse events, increasing the opportunity of patient's early rehabilitation and discharge.
- Early tracheostomy in stroke patients: A meta-analysis and comparison with late tracheostomy(2021) FRANCA, Sabrina Araujo de; TAVARES, Wagner M.; SALINET, Angela S. M.; PAIVA, Wellingson S.; TEIXEIRA, Manoel J.Tracheostomy (TQT) timing and its benefits is a current discussion in medical society. We aimed to compare the outcomes of early (ET) versus late tracheostomy (LT) in stroke patients with systematic review and metaanalysis, according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. Five hundred and nineteen studies were retrieved, whereas three were selected for the systematic review and meta-analysis. There were 5636 patients in the ET group (3151 male, 2470 female, 15 not reported - NR) and 7637 patients in the LT group (4098 male, 3542 female, and 33 NR). ET was significantly associated with fewer days in the hospital (weighted mean difference: -7.73 [95 % CI -8.59-6.86], p < 0.001) and reduced cases of ventilator-associated pneumonia (VAP) (risk difference: 0.71 [95 % CI 0.62-0.81], p < 0.001). There were no between-group statistical differences in intensive care unit stay duration, mechanical ventilation duration, or mortality. The findings from this meta-analysis cannot state that ET in severe stroke patients contributes to better outcomes when compared with LT. Scandalized assessments and randomized trials are encourage for better assessment.

- Distortion Correction Protocol for 3T Stereotactic Magnetic Resonance Imaging: A Clinical Study(2019) TAVARES, Wagner Malago; TUSTUMI, Francisco; LEITE, Claudia da Costa; GAMARRA, Lionel Fernel; AMARO JUNIOR, Edson; TEXEIRA, Manoel Jacobsen; FRANCA, Sabrina Araujo de; FONOFF, Erich TalamoniBACKGROUND: With application of 3T magnetic resonance imaging (MRI) to functional neurosurgery procedures and given the inherent requirement of millimetric precision, the need to develop a method for correction of geometric image distortion emerged. The aim of this study was to demonstrate clinical safety and practical viability of a correction protocol in patients scheduled to undergo stereotactic procedures using 3T MRI. METHODS: This prospective study comprised 20 patients scheduled to undergo computed tomography (CT) stereotactic functional procedures or encephalic brain lesion biopsies. The CT images were references for MRI geometric accuracy calculations. For each scan, 2 images were obtained: normal and reversed images. Eight distinct points on CT and MRI were selected summing 152 points that were based on a power analysis calculation value >0.999. One patient was excluded because of the inability to find reliable common landmark points on CT and MRI. RESULTS: The distortion range was 0-5.6 mm and increased proportionally with stereotactic isocenter distance, meaning the distortion was greater in the periphery. After correction, the minimum and maximum distortion found was 0 mm and 3.5 mm, respectively. There was no significant difference between CT and MRI corrected x-coordinates (P > 0.05). CONCLUSIONS: The proposed method can satisfactorily correct geometric distortions in clinical 3T MRI studies. Clinical use of the technique can be practical and efficient after software automation of the process. The method can be applied to all spin-echo MRI sequences.
- Robotic and standard surgical intervention as adjunct therapies for retroperitoneal ganglioneuroma resection: a case report(2021) TAVARES, Wagner M.; FRANCA, Sabrina Araujo de; VASCONCELOS, Amsterdam S.; PARRA, David S. L.; ARAUJO, Sergio R. R.; TEIXEIRA, Manoel J.BackgroundGanglioneuroma (GN) is ranked by the International Neuroblastoma Pathology Classification as a benign tumor. It can occur anywhere along the sympathetic nerve chain and surgical excision is the treatment of choice.Case presentationAn 18-year-old female patient sought medical assistance after 6 months of constant dorsal and back pain radiating from the thoracic region to the right abdominal flank. Magnetic resonance imaging revealed a solid nodular lesion with heterogeneous post-contrast enhancement and lobulated contours, centered on the right foramina of D12-L1, with a projection to the intracanal space, which compressed and laterally displaced the dural sac and had a right paravertebral extension between the vertebral bodies of D11 and superior aspect of L2. Ganglioneuroma was diagnosed using immunohistochemical analysis. It was decided to use a surgical approach in two stages: robot assisted for the anterior/retroperitoneal mass and a posterior hemilaminectomy/microsurgical approach to attempt total resection, avoiding the traditional anterior thoracoabdominal surgical incision and optimizing the patient's postoperative outcomes. No postoperative adverse events were noted, and the patient was discharged on postoperative day 5.ConclusionThis retroperitoneal GN presentation was peculiar because it originated at the D12 nerve root, which extended to the retroperitoneal space and inside the spinal canal. We hope that our case report can assist future decisions in similar circumstances.

- A systematic review and meta-analysis of fusion rate enhancements and bone graft options for spine surgery(2022) TAVARES, Wagner M.; FRANCA, Sabrina Araujo de; PAIVA, Wellingson S.; TEIXEIRA, Manoel J.Our study aimed to evaluate differences in outcomes of patients submitted to spinal fusion using different grafts measuring the effectiveness of spinal fusion rates, pseudarthrosis rates, and adverse events. Applying the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement, this systematic review and meta-analysis identified 64 eligible articles. The main inclusion criteria were adult patients that were submitted to spinal fusion, autologous iliac crest (AIC), allograft (ALG), alloplastic (ALP; hydroxyapatite, rhBMP-2, rhBMP-7, or the association between them), and local bone (LB), whether in addition to metallic implants or not, was applied. We made a comparison among those groups to evaluate the presence of differences in outcomes, such as fusion rate, hospital stay, follow-up extension (6, 12, 24, and 48 months), pseudarthrosis rate, and adverse events. Sixty-four studies were identified. LB presented significantly higher proportions of fusion rates (95.3% CI 89.7-98.7) compared to the AIC (88.6% CI 84.8-91.9), ALG (87.8% CI 80.8-93.4), and ALP (85.8% CI 75.7-93.5) study groups. Pseudarthrosis presented at a significantly lower pooled proportion of ALG studies (4.8% CI 0.1-15.7) compared to AIC (8.6% CI 4.2-14.2), ALP (7.1% CI 0.9-18.2), and LB (10.3% CI 1.8-24.5). ALP and AIC studies described significantly more cases of adverse events (80 events/404 patients and 860 events/2001 patients, respectively) compared to LB (20 events/311 patients) and ALG (73 events/459 patients). Most studies presented high risk-of-bias scores. Based on fusion rates and adverse events proportions, LB showed a superior trend among the graft cases we analyzed. However, our review revealed highly heterogeneous data and a need for more rigorous studies to better address and assist surgeons' choices of the best spinal grafts.
- Early tracheostomy versus late tracheostomy in severe traumatic brain injury or stroke: A systematic review and meta-analysis(2023) TAVARES, Wagner Malago; FRANCA, Sabrina Araujo de; PAIVA, Wellingson Silva; TEIXEIRA, Manoel JacobsenObjectives: We aim to ascertain whether the benefit of early tracheostomy can be found in patients with severe traumatic brain injury (TBI) and stroke and if the benefit will remain considering distinct pathologies.Data sources: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol, a search through Lilacs, PubMed, and Cochrane databases was conducted. Review methods: Included studies were those written in English, French, Spanish, or Portuguese, with a formulated question, which compared outcomes between early and late trach (minimum of two outcomes), such as intensive care unit (ICU) length of stay (LOS), duration of mechanical ventilation (MV), hospital LOS, mortality rates, or ventilator-associated pneumonia (VAP). Likewise, patients presented exclusively with head injury or stroke had minimum hospital stay follow-up, and as for severe TBI patients, they presented Glasgow Coma Scale <8 at admission. Evaluated outcomes were the risk ratio (RR) of VAP, risk difference (RD) of mortality, and mean difference (MD) of the duration of MV, ICU LOS, and hospital LOS.Results: The early and late tracheostomy cohorts were composed of 6211 and 8140 patients, respectively. The meta-analysis demonstrated that the early tracheostomy cohort had a lower risk for VAP (RR: 0.73 [95% confidence interval {CI}, 0.66, 0.81] p < 0.00001), shorter duration of MV (MD:-4.40 days [95% CI,-8.28,-0.53] p = 0.03), and shorter ICU (MD:-6.93 days [95% CI,-8.75,-5.11] p < 0.00001) and hospital LOS (MD:-7.05 days [95% CI,-8.27,-5.84] p < 0.00001). The mortality rate did not demonstrate a statistical difference.Conclusion: Early tracheostomy could optimise patient outcomes by patients' risk for VAP and decreasing MV durationand ICU and hospital LOS.(c) 2023 Australian College of Critical Care Nurses Ltd.
