Published: January 2021

OBJECTIVEEndovascular removal of emboli causing large vessel occlusion (LVO)–related stroke utilizing suction catheter and/or stent retriever technologies or thrombectomy is a new standard of care. Despite high recanalization rates, 40% of stroke patients still experience poor neurological outcomes as many cases cannot be fully reopened after the first attempt. The development of new endovascular technologies and techniques for mechanical thrombectomy requires more sophisticated testing platforms that overcome the limitations of phantom-based simulators. The authors investigated the use of a hybrid platform for LVO stroke constructed with cadaveric human brains.METHODSA test bed for embolic occlusion of cerebrovascular arteries and mechanical thrombectomy was developed with cadaveric human brains, a customized hydraulic system to generate physiological flow rate and pressure, and three types of embolus analogs (elastic, stiff, and fragment-prone) engineered to match mechanically and phenotypically the emboli causing LVO strokes. LVO cases were replicated in the anterior and posterior circulation, and thrombectomy was attempted using suction catheters and/or stent retrievers.RESULTSThe test bed allowed radiation-free visualization of thrombectomy for LVO stroke in real cerebrovascular anatomy and flow conditions by transmural visualization of the intraluminal elements and procedures. The authors were able to successfully replicate 105 LVO cases with 184 passes in 12 brains (51 LVO cases and 82 passes in the anterior circulation, and 54 LVO cases and 102 passes in the posterior circulation). Observed recanalization rates in this model were graded using a Recanalization in LVO (RELVO) scale analogous to other measures of recanalization outcomes in clinical use.CONCLUSIONSThe human brain platform introduced and validated here enables the analysis of artery-embolus-device interaction under physiological hemodynamic conditions within the unmodified complexity of the cerebral vasculature inside the human brain.
Retrospective analysis of open surgical versus laser interstitial thermal therapy callosotomy in pediatric patients with refractory epilepsy
Authors: Caruso James P. , Janjua M. Burhan , Dolce Alison , Price Angela V. 
Published: January 2021

OBJECTIVE
Corpus callosotomy remains an established surgical treatment for certain types of medically refractory epilepsy in pediatric patients. While the traditional surgical approach is often well tolerated, the advent of MR-guided laser interstitial thermal therapy (LITT) provides a new opportunity to ablate the callosal body in a minimally invasive fashion and minimize the risks associated with an open interhemispheric approach. However, the literature is sparse regarding the comparative efficacy and safety profiles of open corpus callosotomy (OCC) and LITT callosotomy. To this end, the authors present a novel retrospective analysis comparing the efficacy and safety of these methods.

METHODS
Patients who underwent OCC and LITT callosotomy during the period from 2005 to 2018 were included in a single-center retrospective analysis. Patient demographic and procedural variables were collected, including length of stay, procedural blood loss, corticosteroid requirements, postsurgical complications, and postoperative disposition. Pre- and postoperative seizure frequency (according to seizure type) were recorded.

RESULTS
In total, 19 patients, who underwent 24 interventions (16 OCC and 8 LITT), were included in the analysis. The mean follow-up durations for the OCC and LITT cohorts were 83.5 months and 12.3 months, respectively. Both groups experienced reduced frequencies of seizure and drop attack frequency postoperatively. Additionally, LITT callosotomy was associated with a significant decrease in estimated blood loss and decreased length of pediatric ICU stay, with a trend of shorter length of hospitalization.

CONCLUSIONS
Longer-term follow-up and a larger population are required to further delineate the comparative efficacies of LITT callosotomy and OCC for the treatment of pediatric medically refractory epilepsy. However, the authors’ data demonstrate that LITT shows promise as a safe and effective alternative to OCC.

OBJECTIVEThe insula is a complex anatomical structure. Accessing tumors in the insula remains a challenge due to its anatomical complexity and the high chance of morbidity. The goal of this study was to evaluate the feasibility of an endoscopic transorbital approach (ETOA) to the insular region based on a cadaveric study.METHODSOne cadaveric head was used to study the anatomy of the insula and surrounding vessels. Then, anatomical dissection was performed in 4 human cadaveric heads using a dedicated endoscopic system with the aid of neuronavigation guidance. To assess the extent of resection, CT scanning was performed before and after dissection. The insular region was directly exposed by a classic transcranial approach to check the extent of resection from the side with a classic transcranial approach.RESULTSThe entire procedure consisted of two phases: an extradural orbital phase and an intradural sylvian phase. After eyelid incision, the sphenoid bone and orbital roof were extensively drilled out with exposure of the frontal and temporal dural layers. After making a dural window, the anterior ramus of the sylvian fissure was opened and dissected. The M2 segment of the middle cerebral artery (MCA) was identified and traced posterolaterally. A small corticectomy was performed on the posterior orbital gyrus. Through the window between the lateral lenticulostriate arteries and M2, the cortex and medulla of the insula were resected in an anteroposterior direction without violation of the M2 segment of the MCA or its major branches. When confirmed by pterional craniotomy, the sylvian fissure and the MCA were found to be anatomically preserved. After validation of the feasibility and safety based on a cadaveric study, the ETOA was successfully performed in a patient with a high-grade glioma (WHO grade III) in the right insula.CONCLUSIONSThe transorbital route can be considered a potential option to access tumors located in the insula. Using an ETOA, the MCA and its major branches were identified and preserved while removal was performed along the long axis of the insula. In particular, lesions in the anterior part of the insula are most benefited by this approach. Because this approach was implemented in only one patient, additional discussion and further verification is required.

Authors: Wilson Christopher , Hoyos Mariana , Huh Andrew , Priddy Blake , Avila Stephen , Mendenhall Stephen , Anokwute Miracle C. , Eckert George J. , Stockwell David W. 
Published: January 2021

OBJECTIVE
Type II odontoid fractures may be managed operatively or nonoperatively. If managed with bracing, bony union may never occur despite stability. This phenomenon is termed fibrous union. The authors aimed to determine associations with stable fibrous union and compare the morbidity of patients managed operatively and nonoperatively.

METHODS
The authors performed a retrospective review of their spine trauma database for adults with type II odontoid fractures between 2015 and 2019. Two-sample t-tests and Fisher’s exact tests identified associations with follow-up stability and were used to compare operative and nonoperative outcomes. Sensitivity, specificity, and predictive values were calculated to validate initial stable upright cervical radiographs related to follow-up stability.

RESULTS
Among 88 patients, 10% received upfront surgical fixation, and 90% were managed nonoperatively, of whom 22% had fracture instability on follow-up. Associations with instability after nonoperative management include myelopathy (OR 0.04, 95% CI 0.0–0.92), cerebrovascular disease (OR 0.23, 95% CI 0.06–1.0), and dens displacement ≥ 2 mm (OR 0.29, 95% CI 0.07–1.0). Advanced age was not associated with follow-up instability. Initial stability on upright radiographs was associated with stability on follow-up (OR 4.29, 95% CI 1.0–18) with excellent sensitivity and positive predictive value (sensitivity 89%, specificity 35%, positive predictive value 83%, and negative predictive value 46%). The overall complication rate and respiratory failure requiring ventilation on individual complication analysis were more common in operatively managed patients (33% vs 3%, respectively; p = 0.007), even though they were generally younger and healthier than those managed nonoperatively. Operative or nonoperative management conferred no difference in length of hospital or ICU stay, discharge disposition, or mortality.

CONCLUSIONS
The authors delineate the validity of upright cervical radiographs on presentation in association with follow-up stability in type II odontoid fractures. In their experience, factors associated with instability included cervical myelopathy, cerebrovascular disease, and fracture displacement but not increased age. Operatively managed patients had higher complication rates than those managed without surgery. Fibrous union, which can occur with nonoperative management, provided adequate stability.
Effects of end-plate on the critical moment of I-section cantilever beam with free end restrained laterally
Authors: Khanh Trinh Duy , Tuyen Nguyen Minh , Cuong Bui Hung 
Published: January 2021

Effects of end-plate on the lateral buckling of doubly symmetrical I-section cantilever beam with free end restrained laterally are analyzed using the software COMSOL and linear shell finite elements. The torsional stiffness of the end-plate prevents the free warping of flanges and decreases the warping effective length of the cantilever beam. A parametric study is conducted on 3231 cantilever beams under uniform bending to propose an approximative formula to determine the warping effective length factor which depends on the ratio between the torsional constant of the end-plate and the warping stiffness of the beam. The small standard deviation and high coefficient of determination show a very good correlation between analytical formulas and numerical results. Numerical applications are applied to analyze some cantilever beams subjected to uniform bending to demonstrate the reliability of the proposed formula and the effects of the end-plate on the enhancement of the global stability of cantilever beams with free end restrained laterally.

Characterisations of variant transfinite computational models: Infinite time Turing, ordinal time Turing, and Blum–Shub–Smale machines
Authors: Welch Philip 
Published: January 2021

We consider how changes in transfinite machine architecture can sometimes alter substantially their capabilities. We approach the subject by answering three open problems touching on: firstly differing halting time considerations for machines with multiple as opposed to single heads, secondly space requirements, and lastly limit rules. We: 1) use admissibility theory, [Formula: see text]-codes and [Formula: see text]-reflection properties in the constructible hierarchy to classify the halting times of ITTMs with multiple independent heads; the same for Ordinal Turing Machines which have On length tapes; 2) determine which admissible lengths of tapes for transfinite time machines with long tapes allow the machine to address each of their cells – a question raised by B. Rin; 3) characterise exactly the strength and behaviour of transfinitely acting Blum–Shub–Smale machines using a Liminf rule on their registers – thereby establishing there is a universal such machine. This is in contradistinction to the machine using a ‘continuity’ rule which fails to be universal.

Published: January 2021

Introducción: la Organización Mundial de la Salud (OMS) recomienda que la incidencia de cesárea no supere el 15%; sin embargo, su uso se ha incrementado en las dos últimas décadas, lo cual implica un problema de salud pública.Objetivo: caracterizar los resultados adversos maternos y neonatales de la cesárea enla Clínica Maternidad Rafael Calvo (CMRC) de Cartagena Colombia.Materiales y métodos: estudio descriptivo de corte transversal, donde se caracterizaronlos resultados adversos maternos y neonatales posteriores a cesárea.Resultados: se realizaron 1.804 cesáreas (46.5%) y 2.073 partos vaginales (53.5%).Las indicaciones más frecuentes para cesárea fueron cesárea anterior (35.5%), desproporción céfalo pélvica (30.6%) y oligoamnios (10.8%). Los resultados adversos maternos más frecuentes fueron hemorragia que requirió transfusión (9.17%),hematoma en la herida quirúrgica (3.28%) e ingreso a UCI (1.5%). Los resultados neonatales adversos más frecuentes fueron APGAR <7 al minuto (21.3%), taquipnea transitoria del recién nacido (9.6%) y APGAR<7 a los 5´ (4.3%). El control prenatal (CNP) fue factor protector para hemorragia uterina que requirió transfusión (OR crudo 0.54, IC 0.38 – 0.76, OR ajustado 0.53 IC 0.38 – 0.76), hemorragia uterina que requirió histerectomía (OR crudo 0.20, IC 0.01 - 0.72, OR ajustado 0.11, IC 0.11 – 0.72),shock obstétrico (OR crudo 0.06, IC 0.00 – 0.55, OR ajustado, 0.04, IC 0.04 – 0.38) y destino (alojamiento conjunto) (OR ajustado 0.66 IC 0.49 – 0.90), APGAR <7 a 1’ (ORajustado 0.78, IC, 0.44 – 0.72), APGAR <7 a los 5’ (OR ajustado 0.48, IC 0.28 – 0.82)y la presencia de síndrome de distrés respiratorio (OR crudo 0.28, IC, 0.15 – 0.51; ORajustado 0.53, IC 0.28 – 0.98).Conclusiones: la proporción de cesáreas que se realizan en la CMRC (46,5%) es superior al 15% recomendado por la OMS. La operación cesárea conlleva al aumento de morbilidad materno- fetal. El CNP se comportó como factor protector frente a la aparición de resultados adversos maternos y neonatales.
