MALAT1 expression was higher in GB-DM tumors than in GB only tumors. The expression of MALAT1 and HbA1c levels were positively correlated. Additionally, MALAT1 was positively correlated with tumoral p53 and Ki67.

These patients were randomly assigned into training and validation cohorts at a ratio of 2:1. Univariable and multivariable Cox analyses were conducted to determine independent factors of overall survival (OS). A nomogram was then developed using the covariates with the best prognostic value, and the predictive performance of the nomogram was assessed by calibration curves, concordance index, time-dependent receiver operating characteristic curve analysis, and decision curve analysis.Results: A total of 267 cases were included. The OS rates at 6 months, 1 year, and 3 years were 61.6%, 50.1%, and 35.4%, respectively. The results of multivariable Cox analysis showed that tumor extension, surgery type, radiotherapy, and chemotherapy were independent prognostic indicators. A nomogram integrating these factors was established to predict the 6-month, 1-year, and 3-year OS rates. This prediction model was validated in the validation cohort. The nomogram had favorable predictive performance and discrimination ability.Conclusion: We developed and validated a novel nomogram with favorable discrimination ability to predict prognosis for newly diagnosed pediatric ATRT patients. Although additional validation is required, this may be a useful tool in clinical decision making.","PeriodicalId":23395,"journal":{"name":"Turkish neurosurgery","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39432066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The inclusion criteria were preoperative radiculopathy and presence of neurological deterioration without previous surgery. Improved MEP amplitudes reaching the baseline MEP amplitudes of the contralateral side at the same level were used as the thresholds for determining the final disc height and cage size during surgery. Cage size, disc heights of the three areas, foraminal area, and global spinal and local balance were measured.Results: Twenty-two patients (3 male and 19 female) with a mean age of 61.9 ± 8.9 years were included into the study. The mean height of cages was 10.3 ± 1.4 mm (range, 8-14 mm). The mean improvement in MEP amplitude was 27 ± 11% (range, 15-50%). The anterior, middle, and posterior disc heights improved to 2 ± 1.6, 2.7 ± 1.7, and 1.7 ± 1.3 mm, respectively. The improvement in the middle disc height was significantly greater (p < 0.05). Segmental lordosis improved from 16.2° ± 10.7° to 19.4° ± 9.2°. Additionally, lumbar lordosis improved from 46.7° ± 14.6° to 51.2° ± 11.2° (p < 0.05).

However, there was a positive correlation between ipsilateral foraminal area restoration and MEP changes (r=0.501; p < 0.01).Conclusion: Improved MEP amplitudes reaching the baseline MEP amplitudes of the contralateral side of the same spinal level might be a useful threshold for determining the final minimum disc height during TLIF surgery with satisfactory postoperative radiological results, including sagittal and segmental radiological parameters.","PeriodicalId":23395,"journal":{"name":"Turkish neurosurgery","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9845265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The series of patients was enrolled consecutively to minimize selection bias. We quantified comorbid sagittal plane spinal deformity based on the Scoliosis Research Society-Schwab classification system by assessing pelvic incidence and lumbar lordosis mismatch (PI-LL), pelvic tilt (PT), and sagittal vertical axis (SVA).Results: Seventeen patients (59% male) were included in this study. Mean (± standard deviation) age was 74 ± 5.3 years with a body mass index (BMI) of 30 ± 4.5 kg/m 2 . Six patients (35%) had marked sagittal plane spinal deformity by at least one parameter: five (29%) had greater than 20˚ PI-LL mismatch, three (18%) had > 9.5 cm SVA, and one (6%) had PT greater than 30˚. Additionally, the thoracic kyphosis exceeded the lumbar lordosis in nine patients (53%).Conclusion: Positive sagittal balance, with thoracic kyphosis exceeding lumbar lordosis, is common in iNPH patients. This may lead to postural instability, especially in patients whose gait does not improve following shunting. These patients may warrant further investigation and workup, including full length standing x-rays. Future studies should assess for improvement in the sagittal plane parameters following shunt placement.","PeriodicalId":23395,"journal":{"name":"Turkish neurosurgery","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9506872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Further, the clinical and radiographic results were compared by matching the propensity score between the two groups.Results: There were no statistically significant differences in the clinical and angiographic results of the two coils after the propensity score matching. Successful occlusion was 89% and 86.8% and FC insertion failure was 20.9% and 28.6%. There were no differences in procedure-related complications and recurrence between the groups during the eight months follow-up period (3.3% versus 4.4% and 4.4% versus 3.3%, respectively). We also compared two subgroups of failed FC insertion (19 of TG and 26 of MH).

MER were performed in all patient and the maximal electrophysiologic length of the STN was recorded each patient. In the postoperative period, the permanent electrode was modeled and reconstructed in 3D, and the longest distance traveled in the STN was calculated.Results: A total of 61 patients who underwent surgery between 2012-2022 were included in the study. Thirty-six (59%) of the patients were male, and 25 (41%) were female. A total of 122 STNs were performed with 166 electrodes. The most common end alignment used was center with 86. STN length averaged 4.9 mm (0-10.5 mm). The mean STN volume was 0.11 cm3. The STN Volume of men were significantly higher than women. The STN Length, Volume, and the target MER length showed a positive correlation significantly.Conclusion: With radiological advances, it is possible to better visualize the target points and define the boundaries better, and direct methods can be used more in making targeting plans. MER records obtained during surgery and STN dimensions in presurgical planning show compatibility, and it is seen that there may be differences between the right and left sides because of brain shifting.
