Authors: Chrostek Tomasz 
Published: December 2020

Praca dotyczy analizy tworzenia się faz tlenkowych w strukturze intermetalicznych powłok FeAl w warunkach natryskiwania gazodetonacyjnego (GDS). Określono właściwości strukturalne materiału wsadu proszkowego oraz powłoki Fe-Al formowanej in-situ w procesie GDS. Przeanalizowano skutki procesu GDS na zmiany fazowe powłoki FeAl natryskanej w kontrolowanych warunkach GDS. Uzyskane wyniki wykazują, że przy określonych parametrach procesu GDS cząstki proszku FeAl poddawane są silnemu utlenianiu w gorącym strumieniu gazowych produktów spalania detonacyjnego z przepływem naddźwiękowym. Skutkuje to tworzeniem się wielofazowej struktury powłoki z udziałem faz tlenkowych formowanych po granicach ziaren w postaci cienkich błonek, wskutek bardzo silnego odkształcenia plastycznego cząstek proszku formujących powłokę.
Uzyskane wyniki badań strukturalnych, mikroanalizy składu chemicznego SEM/EDS oraz składu fazowego XRD, wykazały, że bardzo silnie nagrzane cząstki FeAl w warunkach GDS, ulegają powierzchniowo silnemu utlenieniu, przekształcając się w ziarna w formie splatów, po zderzaniu z materiałem stalowego podłoża. W rezultacie, tworzy się warstwowa, wielofazowa struktura powłoki na osnowie fazy FeAl dziedziczonej z materiału proszkowego z udziałem cienkich warstw tlenkowych, głównie Al2O3.

Published: December 2020

Introduction : Notre objectif était d’analyser la survie des patients victimes d’un arrêt cardiaque extrahospitalier (ACEH) durant la pandémie Covid-19 et de comparer les données en fonction du centre de traitement de l’appel choisi, le 15 ou le 18.
Méthode : Nous avons extrait les données exhaustives du Registre des arrêts cardiaques (RéAC), entre le 1er mars et le 30 avril 2020. Nous avons effectué trois comparaisons de la survie à 30 jours (J30) de cohortes de patients : 1) Covid vs non-Covid ; 2) appels arrivés au service d’aide médicale urgente (Samu) (15) vs aux sapeurs-pompiers (SP) (18) et 3) appels arrivés au 15 vs 18 pour les patients Covid.
Résultats : Sur un total de 870 ACEH, 184 étaient atteints de la Covid. Nous avons observé 487 (56 %) appels arrivés au 15 et 383 (44 %) au 18. La survie à J30 était de 3 %. Les ACEH Covid avaient une survie à J30 plus faible que les non-Covid (0 vs 4 %, p < 0,001). Le délai d’arrivée de SP était plus long lors d’un appel au 15. En revanche, aucune différence de survie n’est observée entre les appels arrivés au 15 ou au 18.
Conclusion : La survie consécutive à un ACEH durant la pandémie est extrêmement faible. Cependant, quel que soit le numéro composé (15 ou 18), la survie n’est pas différente, même si le délai d’arrivée des prompts secours est plus court lors d’un appel au 18.

OBJECTIVEImaging evaluation of the cerebral ventricles is important for clinical decision-making in pediatric hydrocephalus. Although quantitative measurements of ventricular size, over time, can facilitate objective comparison, automated tools for calculating ventricular volume are not structured for clinical use. The authors aimed to develop a fully automated deep learning (DL) model for pediatric cerebral ventricle segmentation and volume calculation for widespread clinical implementation across multiple hospitals.METHODSThe study cohort consisted of 200 children with obstructive hydrocephalus from four pediatric hospitals, along with 199 controls. Manual ventricle segmentation and volume calculation values served as “ground truth” data. An encoder-decoder convolutional neural network architecture, in which T2-weighted MR images were used as input, automatically delineated the ventricles and output volumetric measurements. On a held-out test set, segmentation accuracy was assessed using the Dice similarity coefficient (0 to 1) and volume calculation was assessed using linear regression. Model generalizability was evaluated on an external MRI data set from a fifth hospital. The DL model performance was compared against FreeSurfer research segmentation software.RESULTSModel segmentation performed with an overall Dice score of 0.901 (0.946 in hydrocephalus, 0.856 in controls). The model generalized to external MR images from a fifth pediatric hospital with a Dice score of 0.926. The model was more accurate than FreeSurfer, with faster operating times (1.48 seconds per scan).CONCLUSIONSThe authors present a DL model for automatic ventricle segmentation and volume calculation that is more accurate and rapid than currently available methods. With near-immediate volumetric output and reliable performance across institutional scanner types, this model can be adapted to the real-time clinical evaluation of hydrocephalus and improve clinician workflow.

OBJECTIVEGross-total resection (GTR) is the treatment of choice in the majority of patients suffering from spinal ependymal tumors. In such tumors, the extent of resection (EOR) is considered the key factor for tumor recurrence and thus patient prognosis. However, incomplete resection is not uncommon and leads to increased risk of tumor recurrence. One important cause of incomplete resection is insufficient intraoperative visualization of tumor tissue as well as residual tumor tissue. Therefore, the authors investigated the value of 5-aminolevulinic acid (5-ALA)–induced fluorescence in a series of spinal ependymal tumors for improved tumor visualization.METHODSAdult patients who underwent preoperative 5-ALA administration and surgery for a spinal ependymal tumor were included in this study. For each tumor, a conventional white-light microsurgical resection was performed. Additionally, the fluorescence status (strong, vague, or no fluorescence) and fluorescence homogeneity (homogenous or inhomogeneous) of the spinal ependymal tumors were evaluated during surgery using a modified neurosurgical microscope. In intramedullary tumor cases with assumed GTR, the resection cavity was investigated for potential residual fluorescing foci under white-light microscopy. In cases with residual fluorescing foci, these areas were safely resected and the corresponding samples were histopathologically screened for the presence of tumor tissue.RESULTSIn total, 31 spinal ependymal tumors, including 27 intramedullary tumors and 4 intradural extramedullary tumors, were included in this study. Visible fluorescence was observed in the majority of spinal ependymal tumors (n = 25, 81%). Of those, strong fluorescence was noted in 23 of these cases (92%), whereas vague fluorescence was present in 2 cases (8%). In contrast, no fluorescence was observed in the remaining 6 tumors (19%). Most ependymal tumors demonstrated an inhomogeneous fluorescence effect (17 of 25 cases, 68%). After assumed GTR in intramedullary tumors (n = 15), unexpected residual fluorescing foci within the resection cavity could be detected in 5 tumors (33%). These residual fluorescing foci histopathologically corresponded to residual tumor tissue in all cases.CONCLUSIONSThis study indicates that 5-ALA fluorescence makes it possible to visualize the majority of spinal ependymal tumors during surgery. Unexpected residual tumor tissue could be detected with the assistance of 5-ALA fluorescence in approximately one-third of analyzed intramedullary tumors. Thus, 5-ALA fluorescence might be useful to increase the EOR, particularly in intramedullary ependymal tumors, in order to reduce the risk of tumor recurrence.
Radiological predictors of recurrent lumbar disc herniation: a systematic review and meta-analysis

Published: December 2020

OBJECTIVELumbar discectomy for the management of lumbar radiculopathy is a commonly performed procedure with generally excellent patient outcomes. However, recurrent lumbar disc herniation (rLDH) remains one of the most common complications of the procedure, often necessitating repeat surgery. rLDH is known to be influenced by a variety of factors, and in this systematic review the authors aimed to explore the radiological predictors of recurrence.METHODSA systematic review and meta-analysis was conducted to identify studies analyzing radiological predictors of recurrent herniation, both ipsilateral and contralateral. A search was conducted on Medline and EMBASE. Both retrospective and prospective comparative studies were included, measuring radiological parameters of lumbar discectomy patients. All factors were considered irrespective of imaging modality, and a meta-analysis of the data was performed in which 5 or more studies were identified analyzing the same parameter.RESULTSIn total, 1626 reported studies were screened, with 23 being included in this review, of which 13 were appropriate for meta-analysis. Three factors, namely disc height index, Modic changes, and sagittal range of motion, were determined to be significantly correlated with an increased rate of rLDH. Some variables were considered in only 1 or 2 different studies, and the authors have included a narrative review of these novel findings.CONCLUSIONSThe findings of associations between the radiological parameters and rLDH implicates the role of instability in the development of recurrence. Understanding the physiological factors associated with instability is important, because although early degenerative disc changes may predispose patients to herniation recurrence, more advanced degeneration likely reduces segmental motion and concurrently risk of recurrence.

OBJECTIVE
Early surgery in presumed asymptomatic patients with incidental low-grade glioma (ILGG) has been suggested to improve maximal resection rates and overall survival. However, no study has reported on the impact of such preventive treatment on cognitive functioning. The aim of this study was to investigate neuropsychological outcomes in patients with ILGG who underwent preventive surgery.

METHODS
This was a retrospective analysis of a consecutive series of patients with ILGG who underwent awake surgery and who had presurgical and 3-month postsurgical neuropsychological assessments. Data were normalized into z-scores and regrouped by cognitive domains. Clinicoradiological data, histomolecular profile, and differences in z-scores (Δz-scores) were analyzed.

RESULTS
Forty-seven patients were included (mean age 39.2 ± 11.3 years). Twenty-eight patients (59.6%) underwent supratotal or total resections. All patients were still alive after a mean follow-up of 33.0 ± 30.8 months. Forty-one patients (87.2%) had stable (n = 34, 72.3%) or improved (Δz-score > 1; n = 7, 14.9%) neurocognitive outcomes after surgery. Six patients (12.8%) presented a slight impairment (Δz-score < −1) in at least one cognitive domain. The mean presurgical and postsurgical z-scores were comparable except in the psychomotor speed and attention domain. A significant correlation between presurgical executive functioning and tumor volume was reported, whereas the extent of resection and histomolecular profile did not impact neuropsychological outcomes.

CONCLUSIONS
Early surgical treatment in presumed asymptomatic patients with ILGG was associated with stable or improved neuropsychological outcomes in 87.2% of patients at 3 months, with only mild cognitive decline observed in 6 patients. In return, supratotal or total resections were achieved in most patients, and all patients were still alive at the end of the follow-up.

OBJECTIVEThe primary treatment for atlantoaxial rotatory fixation (AARF) remains controversial. The aim of this study was to investigate the primary treatment for AARF and create an algorithm for primary treatment.METHODSThe authors analyzed the data of 125 pediatric patients at four medical institutions from April 1989 to December 2018. The patients were reported to have neck pain, torticollis, and restricted neck range of motion and were diagnosed according to the Fielding classification as type I or II. As a primary treatment, 88 patients received neck collar fixation, and 28 of these patients did not show symptom relief and required Glisson traction. Thirty-seven patients were primarily treated with Glisson traction. In total, 65 patients, including neck collar treatment failure patients, underwent Glisson traction in hospitals.RESULTSThe success rate of treatment was significantly higher in the Glisson traction group (97.3%) than in the neck collar fixation group (68.2%) (p = 0.0001, Wilcoxon test). In the neck collar effective group, Fielding type I was more predominant (p = 0.0002, Wilcoxon test) and the duration from onset to the first visit was shorter (p = 0.02, Wilcoxon test) than that in the neck collar ineffective group. Using multivariate logistic regression analysis with the above items, the authors generalized from the estimated formula: logit [p(success group by neck collar fixation group)|duration from onset to the first visit (x1), Fielding type (x2)] = 0.4(intercept) − 0.15x1 + 1.06x2, where x1 is the number of days and x2 = 1 (for Fielding type I) or −1 (for Fielding type II). In cases for which the score is a positive value, the neck collar should be chosen. Conversely, in cases for which the score is a negative value, Glisson traction should be the first choice.CONCLUSIONSAccording to this formula, in patients with Fielding type I AARF, neck collar fixation should be allowed only if the duration from onset is ≤ 10 days. In patients with Fielding type II, because the score would be a negative value, Glisson traction should be performed as the primary treatment.

OBJECTIVEThe purpose of this study was to compare the preoperative radiographic features of degenerative lumbar spondylolisthesis (DLS) with and without local coronal imbalance (LCI) and to investigate the surgical outcomes of transforaminal lumbar interbody fusion (TLIF) in the treatment of DLS with LCI at the spondylolisthesis level. DLS with scoliotic disc wedging and/or lateral listhesis at the same involved segment, as well as LCI, constitutes a distinct subgroup. However, previous studies concerning surgical outcomes focused mainly on sagittal profiles. There is a paucity of valid data regarding lumbar coronal alignment and patient-reported outcomes (PROs) after surgery in DLS with LCI.METHODSThe authors reviewed consecutive patients who received TLIF for L4/5 DLS between 2009 and 2018. Patients were assigned to the LCI and non-LCI groups based on preoperative radiographs. Demographics, radiographic parameters related to both sagittal and coronal alignment, and PROs were compared between the 2 groups.RESULTSThere were 21 patients in the LCI and 80 in the non-LCI group. Compared with the non-LCI group, the LCI group was characterized by lower preoperative lumbar lordosis on sagittal alignment (38.3° vs 43.7°, p < 0.05), higher lumbar Cobb angle on coronal alignment (12.4° vs 5.1°, p < 0.05), and worse lumbar coronal balance (18.5 mm vs 6.8 mm, p < 0.05). After surgery, lumbar alignment in the sagittal and coronal planes was significantly improved in the LCI group, whereas no significant changes occurred in the non-LCI group. Scores on the preoperative Oswestry Disability Index and the visual analog scale for back pain and leg pain scores were significantly higher in the LCI group, whereas no differences were found between the 2 groups in the postoperative evaluation (p > 0.05).CONCLUSIONSDLS with LCI constitutes a distinct subgroup characterized by coronal malalignment and loss of whole lumbar lordosis, which may result in worse PROs. The TLIF procedure allows the reconstruction of the coronal and sagittal lumbar profile and achievement of satisfactory PROs.
