Abstract
Pancreatic β-cells respond to metabolic stress by upregulating insulin secretion, however the underlying mechanisms remain unclear. Here we show, in β-cells from overweight humans without diabetes and mice fed a high-fat diet for 2 days, insulin exocytosis and secretion are enhanced without increased Ca2+ influx. RNA-seq of sorted β-cells suggests altered metabolic pathways early following high fat diet, where we find increased basal oxygen consumption and proton leak, but a more reduced cytosolic redox state. Increased β-cell exocytosis after 2-day high fat diet is dependent on this reduced intracellular redox state and requires the sentrin-specific SUMO-protease-1. Mice with either pancreas- or β-cell-specific deletion of this fail to up-regulate exocytosis and become rapidly glucose intolerant after 2-day high fat diet. Mechanistically, redox-sensing by the SUMO-protease requires a thiol group at C535 which together with Zn+-binding suppresses basal protease activity and unrestrained β-cell exocytosis, and increases enzyme sensitivity to regulation by redox signals.

Abstract
The identification of vertebral fracture is a key point in an FLS. We have analyzed the characteristics of 570 patients according to the route of identification (referral by other doctors, emergency registry or through VFA), concluding that promoting referral by other doctors with a training campaign is effective. PURPOSE Vertebral fractures (VF) are associated with increased risk of further VFs. Our objective was to analyze the characteristics of patients with VF seen in a Fracture Liaison Service (FLS). METHODS An observational study was carried out on patients with VF referred to the outpatient metabolic clinic (OMC) after a training campaign, identified in the emergency registry, and captured by VF assessment with bone densitometry (DXA-VFA) in patients with non-VFs. Patients with traumatic VF or VF > 1 year, infiltrative or neoplastic disease were excluded. The number and severity of VFs (Genant) were analyzed. Treatment initiation in the first 6 months after baseline visit was reviewed. RESULTS Overall, 570 patients were included, mean age 73. The most common route for identifying VF was through referral to OMC (303 cases), followed by the emergency registry (198) and DXA-VFA (69). Osteoporosis by DXA was found in 312 (58%) patients and 259 (45%) had ≥ 2 VFs. The rate of grade 3 VFs was highest among patients on the emergency registry. Those identified through OMC had a higher number of VFs, a higher rate of osteoporosis, more risk factors and greater treatment initiation. Patients with VFs detected by DXA-VFA were mostly women with a single VF and had a lower rate of osteoporosis by DXA. CONCLUSIONS We present the distribution of VFs by the route of identification in an FLS. Promoting referral by other doctors with a training campaign may help in the quality improvement of the FLS-based model of care.

Abstract
Due to a worldwide response to the COVID-19 pandemic, many changes were imposed on individuals' daily lives, including those related to the physical activity of children and adolescents. The present study aims to comprehend the impact of early COVID-19 pandemic restrictions on Portuguese adolescents' physical fitness parameters during two school years. A total of 640 students from the 5th to the 12th grades participated in the longitudinal study. Data on body composition, aerobic fitness, speed, agility, lower and upper body strength, and flexibility were collected at three moments: 1. before the COVID-19 pandemic (December 2019); 2. after the COVID-19 lockdown when the schools reopened delivering in-person classes (October 2020), and 3. two months after the in-person classes started (December 2020). To analyze the overall changes between the three moments and between two age groups, we conducted repeated measure ANOVAs. The main findings indicate that participants' body composition (i.e., waist circumference) and aerobic fitness (i.e., maximal oxygen uptake) deteriorated after the first lockdown but improved two months after the in-person classes started. However, the same did not happen to neuromuscular fitness (i.e., horizontal Jumps and Sit and Reach). These findings suggest that the COVID-19 lockdown may have negatively impacted adolescents' physical fitness, particularly older adolescents. Altogether, data reinforce the importance of in-person classes and school context in promoting adolescents' physical health.

Abstract
PURPOSE Spinal osteotomies performed to treat fixed spinal deformities are technically demanding and associated with a high complications rate. The main purpose of this study was to analyze complications and their risk factors in spinal osteotomies performed for fixed sagittal imbalance from multiple etiologies. METHODS The study consisted of a blinded retrospective analysis of prospectively collected data from a large multicenter cohort of patients who underwent 3-columns (3C) spinal osteotomy, between January 2010 and January 2017. Clinical and radiological data were compared pre- and post-operatively. Complications and their risk factors were analyzed. RESULTS Two hundred eighty-six 3C osteotomies were performed in 273 patients. At 1 year follow-up, both clinical (VAS pain, ODI and SRS-22 scores) and radiological (SVA, SSA, loss of lordosis and pelvic version) parameters were significantly improved (p < 0.001). A total of 164 patients (59.2%) experienced at least 1 complication (277 complications). Complications-free survival rates were only 30% at 5 years. Most of those were mechanical (35.2%), followed by general (17.6%), surgical site infection (17.2%) and neurological (10.9%). Pre-operative neurological status [RR = 2.3 (1.32-4.00)], operative time (+ 19% of risk each additional hour) and combined surgery [RR = 1.76 (1.08-2.04)] were assessed as risk factors for overall complication (p < 0.05). The use of patient-specific rods appeared to be significantly associated with less overall complications [RR = 0.5 (0.29-0.89)] (p = 0.02). CONCLUSION Spinal 3C osteotomies were efficient to improve both clinical and radiological parameters despite high rates of complication. Efforts should be made to reduce operative time which appears to be the strongest predictive risk factor for complication.

Abstract
OBJECTIVE In non-alcoholic fatty liver disease (NAFLD), fibrosis determines the risk of liver complications. Non-invasive tests (NITs) such as FIB-4, NAFLD Fibrosis Score (NFS) and Hepamet, have been proposed as a tool to triage NAFLD patients in primary care (PC). These NITs include AST±ALT in their calculations. Many patients with NAFLD take statins, which can affect AST/ALT, but it is unknown if statin affects NITs fibrosis prediction. METHODS We included 856 patients referred through a standardised pathway from PC with a final diagnosis of NAFLD. 832 had reliable vibration controlled transient elastography (VCTE) measurements. We assessed the effects of statins on the association between NITs and VCTE at different fibrosis thresholds. RESULTS 129 out of 832 patients were taking a statin and 138 additional patients had indication for a statin. For any given FIB-4 value, patients on a statin had higher probabilities of high VCTE than patients not on a statin. Adjusting for body mass index, diabetes and age almost completely abrogated these differences, suggesting that these were related to patient's profile rather to a specific effect of statins. Negative predictive values (NPVs) of FIB-4 <1.3 for VCTE >8, 10, 12 and 16 were, respectively, 89, 94, 96% and 100% in patients on a statin and 92, 95, 98% and 99% in patients not on a statin. Statins had similar impact on Hepamet predictions but did not modify NFS predictions. CONCLUSION In patients with NAFLD referred from PC, those on statins had higher chances of a high VCTE for a given FIB-4 value, but this had a negligible impact on the NPV of the commonly used FIB-4 threshold (<1.3).

Abstract
This paper discusses the structure, particle morphology, and optical properties of un-doped ZnO and ZnO doped with Er3+ and Yb3+ lanthanide ion nanoparticles (NPs) through a process denominated sol-gel-hydrothermal. According to the pattern of X-ray diffraction, ZnO:Er and ZnO:Yb is formed by a single-phase wurtzite structure with crystallites sized ~65 nm on average, and Er or Yb dopant ions in the hexagonal structure of ZnO, specifically in its distorted lattice sites. The results also suggest the possible role of oxygen vacancies or Ox- (defects) in the energy transfer from ZnO to the Er or Yb ions with a decrease of 3.18 eV and 3.19 eV in bandgap values to a red shift.

Abstract
INTRODUCTION Deformity associating coronal and sagittal malalignment can severely impair quality of life in Parkinson's disease (PD). Realignment using patient-specific rods (PSRs) is useful for achieving alignment goals. METHODS This was a retrospective single-center analysis of a prospectively maintained database of all PD patients who underwent surgery between January 2013 and January 2017. Clinical evaluation, preoperatively and at 1 year's follow-up, used the Oswestry Disability Index (ODI). Radiological evaluation used systematic preoperative and 1-year postoperative full-spine radiographs. RESULTS Twelve patients were included: 6 female, 6 male; mean age, 68.4 years. Mean follow-up was 40.8 months [range 12-70]. On average, 14 levels were fused [range 10-18]. Unplanned revision surgery was necessary for 8 patients at a mean 15.625 months after index surgery. Mean preoperative ODI score was 64% preoperatively [range 56-70] versus 52% [range 28-64] at 1 year's follow-up (P=0.004). Lumbar lordosis improved significantly, from -16.7° preoperatively to -41.4° at 1 year (P=0.006). Pelvic tilt was the least effectively corrected parameter, with a mean preoperative value of 31.6° vs. 27.8° at 1 year (P=0.19). Mean preoperative sagittal vertical axis was 149.7mm versus 73.6mm at 1 year (P=0.013). Mean preoperative coronal tilt was 68.2mm versus 22.9mm at 1 year (P=0.007). CONCLUSION Parkinson's disease is a degenerative disease frequently associated with major spine malalignment. The severity of the postural disorders in these patients needs special precautions to avoid complications.

Abstract
Background HIV drug resistance (HIV-DR) is rising in sub-Saharan Africa in both ART-naive and ART-experienced patients. Objectives To estimate the level of acquired DR (ADR) and pre-treatment DR (PDR) across selected urban and rural sites in Southern Africa, in Mozambique. Methods We conducted two cross-sectional surveys among adult HIV patients (October 2017–18) assessing ADR and PDR. In the (ADR) survey, those on NNRTI-based first-line ART for ≥6 months were recruited (three sites). In the PDR survey, those ART-naive or experienced with ≥3 months of treatment interruption prior were enrolled (eight sites). Results Among 1113 ADR survey participants 83% were receiving tenofovir (TDF)/lamivudine (3TC)/efavirenz (EFV). The median time on ART was 4.5 years (Maputo) and 3.2 years (Tete), 8.3% (95% CI 6.2%-10.6%, Maputo) and 15.5% (Tete) had a VL ≥ 1000 copies/mL, among whom 66% and 76.4% had NNRTI+NRTI resistance, and 52.8% and 66.7% had 3TC+TDF-DR. Among those on TDF regimens, 31.1% (Maputo) and 42.2% (Tete) were still TDF susceptible, whereas 24.4% and 11.5% had TDF+zidovudine (ZDV)-DR. Among those on ZDV regimens, 25% and 54.5% had TDF+ZDV-DR. The PDR survey included 735 participants: NNRTI-PDR was 16.8% (12.0–22.6) (Maputo) and 31.2% (26.2–36.6) (Tete), with a higher proportion (≥50%) among those previously on ART affected by PDR. Conclusions In Mozambique, viral failure was driven by NNRTI and NRTI resistance, with NRTI DR affecting backbone options. NNRTI-PDR levels surpassed the WHO 10% ‘alert’ threshold. Replacing NNRTI first-line drugs is urgent, as is frequent viral load monitoring and resistance surveillance. Changing NRTI backbones when switching to second-line regimens may need reconsideration.

Abstract
OBJECTIVE The aim of this study was to describe progestin-associated meningiomas' characteristics, outcome and management. MATERIAL AND METHODS We included 53 patients operated on and/or followed in the department for meningioma with progestin intake longer than one year and with recent drug discontinuation. RESULTS Cyproterone acetate (CPA), nomegestrol acetate (NomA), and chlormadinone acetate (ChlA) were involved in most cases. Mean duration of progestin drugs intake was 17.5 years. Tumors were multiple in 66% of cases and were located in the anterior and the medial skull base in 71% of cases. Transitional subtype represented 16/25 tumors; 19 meningiomas were WHO grade I and 6 were grade II. The rate of transitional subtype and skull base location was significantly higher compared to matched operated meningioma general population. No difference was observed given WHO classification. But Ki67 proliferation index tends to be lower and 5/6 of the WHO grade II meningiomas were classified as WHO grade II because of brain invasion. Strong progesterone receptors expression was observed in most cases. After progestin discontinuation, a spontaneous visual recovery was observed in 6/10 patients. Under CPA (n=24) and ChlA/NomA (n=11), tumor volume decreased in 71% and 18% of patients, was stabilized in 25% and 64% of patients, and increased in 4% and 18% of patients, respectively. Volume outcome was related to meningioma location. CONCLUSIONS Outcome at progestins discontinuation is favorable but different comparing CPA versus ChlA-NomA and comparing tumor location. Long-term follow-up is required. In most cases, simple observation is recommended and surgery should be avoided.

Abstract
PURPOSE Nocardia farcinica is an opportunistic pathogen causing mainly pneumonia in immunocompromised patients, complicated in almost one-third of the cases by a thick-walled multiloculated cerebral abscess which induces significant morbidity and mortality. This review aims to assess the optimal treatment strategy for N. farcinica cerebral abscess. METHODS Report of a case. Medline database was used to conduct a systematic review from inception to January 2020 looking for English-language articles focused on N. farcinica cerebral abscess, in accordance with the PRISMA guidelines. RESULTS The research yielded 54 articles for a total of 58 patients. N. farcinica cerebral abscess displayed three different neuroimaging patterns: a single multiloculated abscess in half of the cases, multiple cerebral abscesses, or a small paraventricular abscess with meningitis. The patients who benefited from surgical excision of the abscess showed a trend towards a lower risk of surgical revision (8% versus 31%, P=0.06) and a lower mortality rate (8% versus 23%, P=0.18) than patients who benefited from needle aspiration. Twenty-two percent of the patients benefited from microbiological documentation from another site with a mortality rate of 23%. CONCLUSION Urgent multimodal MRI is necessary in face with clinical suspicion of cerebral nocardiosis. In case of single or multiple small cerebral abscesses, microbiological documentation can be obtained with puncture of pseudotumoral visceral lesions. In case of large or symptomatic cerebral abscess, an aggressive surgical excision seems a reliable option and can be preferred over needle aspiration. Long-term antibiotic therapy with cotrimoxazole is necessary thereafter.

Abstract
BACKGROUND Odontoid fracture is a common injury in the upper cervical spine that can sometimes be managed by anterior odontoid screw fixation. CASE DESCRIPTION We report the first case of iatrogenic postero-inferior cerebellar artery (PICA) injury while performing anterior odontoid screw fixation for a type II odontoid fracture in a 22-year-old man. Fisher grade 4 subarachnoid hemorrhage secondary to iatrogenic pseudoaneurysm formation was managed by the endovascular neuroradiologist. Odontoid fracture was then managed posteriorly using Harm's technique. Postoperative 12-month follow-up revealed good clinical and radiological results. CT scan showed fusion. Complete exclusion of the pseudo aneurysm with a mild stroke in the inferior left cerebellar hemisphere were noted on the MRI. There were no cerebellar ataxia or swallowing disorders. CONCLUSION To the best of our knowledge, this is the first case report of iatrogenic PICA injury in anterior odontoid screw fixation. The patient was well managed in our institution within a multidisciplinary team. We recommend that surgical management of odontoid fractures should be performed in expert centres.

Abstract
BACKGROUND C1-C2 injury represents 25-40% of cervical injuries and predominantly occurs in the geriatric population. METHODS A prospective multicentre study was conducted under the aegis of the french spine surgery society (SFCR) investigating the impact of age, comorbidities, lesion type, and treatment option on mortality, complications, and fusion rates. RESULTS A total of 417 patients were recruited from 11 participating centres. The mean ± SD age was 66.6 ± 22 years, and there were 228 men (55%); 5.4% presented a neurological deficit at initial presentation. The most frequent traumatic lesion was C2 fracture (n = 308). Overall mortality was 8.4%; it was 2.3% among those aged ≤ 60 years, 5.0% 61-80 years, and 16.0% > 80 years (p < 0.001). Regarding complications, 17.8% of patients ≤ 70 years of age presented with ≥ 1 complication versus 32.3% > 70 years (p = 0.0009). The type of fracture did not condition the onset of complications and/or mortality (p > 0.05). The presence of a comorbidity was associated with a risk factor for both death (p = 0.0001) and general complication (p = 0.008). Age and comorbidities were found to be independently associated with death (p < 0.005). The frequency of pseudoarthrosis ranged from 0 to 12.5% up to 70 years of age and then constantly and progressively increased to reach 58.6% after 90 years of age. CONCLUSIONS C1-C2 injury represents a serious concern, possibly life-threatening, especially in the elderly. We found a major impact of age and comorbidities on mortality, complications, and pseudarthrosis; injury pattern or treatment option seem to have a minimal effect.

Abstract
INTRODUCTION Complex spinal surgery is known to be at risk of complications. Surgical site infection is a serious complication in spine surgery and its frequency is significantly increased in adult spinal deformity correction. The aim of this study is to identify patients' characteristics and risk factors of surgical site infection (SSI) following an osteotomy. METHODS This is a single-center retrospective study of patients who underwent an osteotomy between January 2015 and December 2017. Surgical site infection diagnosis was based upon patient's clinical evidence of infection, biologic parameters, microbiological criteria and/or image findings. RESULTS In total, 102 patients were eligible and 70 were women (68.6%). Mean age was 65 years old (27-83 years) and mean body mass index (BMI) was 26.14kg.m-2 (18.4-44.1). Eleven patients were in the SSI group and 91 in the No-SSI group. The mean Schwab grade was 1.5 (1-4) in the SSI group vs. 1.4 (1-5) in the No-SSI group (P=0.435). The mean operative time was on 201.9 minutes (67-377). Mean length of stay was 20.6 days (10-73) in the SSI group vs. 15 days (5-44) in the No-SSI group (P=0.041). Favorable outcome was found in 10 patients (90.9%) in the SSI group. CONCLUSION Correction surgery for adult spinal deformity with osteotomies carries a high risk of complications specially SSI. Identification of risk factors, prevention and medical management of SSI should be well assessed.

Abstract
Abstract
Background
The use of artificial intelligence is increasing to estimate and predict health outcomes from large data sets. The main objectives were to develop two algorithms using machine learning techniques to identify new cases of diabetes (case study I) and to classify type 1 and type 2 (case study II) in France.
Methods
We selected the training data set from a cohort study linked with French national Health database (i.e., SNDS). Two final datasets were used to achieve each objective. A supervised machine learning method including eight following steps was developed: the selection of the data set, case definition, coding and standardization of variables, split data into training and test data sets, variable selection, training, validation and selection of the model. We planned to apply the trained models on the SNDS to estimate the incidence of diabetes and the prevalence of type 1/2 diabetes.
Results
For the case study I, 23/3468 and for case study II, 14/3481 SNDS variables were selected based on an optimal balance between variance explained and using the ReliefExp algorithm. We trained four models using different classification algorithms on the training data set. The Linear Discriminant Analysis model performed best in both case studies. The models were assessed on the test datasets and achieved a specificity of 67% and a sensitivity of 62% in case study I, and a specificity of 97 % and sensitivity of 100% in case study II. The case study II model was applied to the SNDS and estimated the prevalence of type 1 diabetes in 2016 in France of 0.3% and for type 2, 4.4%. The case study model I was not applied to the SNDS.
Conclusions
The case study II model to estimate the prevalence of type 1/2 diabetes has good performance and will be used in routine surveillance. The case study I model to identify new cases of diabetes showed a poor performance due to missing necessary information on determinants of diabetes and will need to be improved for further research.

Abstract
OBJECT In recent years, the classical vertebroplasty has tended to be replaced by vertebral augmentation procedures. This article discusses the reliability of vertebral augmentation procedures using balloon kyphoplasty or a spine jack system, with intraoperative CT scan control coupled with the neuronavigation system as a treatment option for cervical and upper thoracic spine lesions. METHODS In our neurosurgical department, in the past two years, 11 patients underwent either a kyphoplasty or a vertebral augmentation by a Spine Jack via a transpedicular route, under perioperative 3D imaging, for a total of 15 cervical/upper thoracic lesions. For these patients, we evaluated the clinical symptoms before and after surgery, the intraoperative and postoperative complications as well as the radiation exposure and the duration of their hospitalisation. RESULTS We noted for all of the patients an improvement of the mean Karnofsky index, which improved from 50 to 80, and of the VAS that decreased from a mean of 75 to 15, as they were clearly alleviated after the operation. The radiation was lower for patients that were treated for 2 or more vertebrae, and much lower for the medical staff. The intraoperative complications rate (4 cement leakages for 15 vertebrae, 26%), was low and completely asymptomatic in all cases. The radiological follow-up examinations were satisfactory for all the patients. CONCLUSIONS Our results suggest that percutaneous transpedicular vertebral augmentation techniques using intraoperative CT scan are a viable treatment for secondary lesions or traumatic compression fractures of the cervical and upper thoracic spine.

Abstract
OBJECTIVES To update the French guidelines on the management of trauma patients with spinal cord injury or suspected spinal cord injury. DESIGN A consensus committee of 27 experts was formed. A formal conflict-of-interest (COI) policy was developed at the outset of the process and enforced throughout. The entire guidelines process was conducted independently of any industrial funding (i.e. pharmaceutical, medical devices). The authors were advised to follow the rules of the Grading of Recommendations Assessment, Development and Evaluation (GRADE®) system to guide assessment of quality of evidence. The potential drawbacks of making strong recommendations in the presence of low-quality evidence were emphasised. METHODS The committee studied twelve questions: (1) What are the indications and arrangements for spinal immobilisation? (2) What are the arrangements for pre-hospital orotracheal intubation? (3) What are the objectives of haemodynamic resuscitation during the lesion assessment, and during the first few days in hospital? (4) What is the best way to manage these patients to improve their long-term prognosis? (5) What is the place of corticosteroid therapy in the initial phase? (6) What are the indications for magnetic resonance imaging in the lesion assessment phase? (7) What is the optimal time for surgical management? (8) What are the best arrangements for orotracheal intubation in the hospital environment? (9) What are the specific conditions for weaning these patients from mechanical ventilation for? (10) What are the procedures for analgesic treatment of these patients? (11) What are the specific arrangements for installing and mobilising these patients? (12) What is the place of early intermittent bladder sampling in these patients? Each question was formulated in a PICO (Patients, Intervention, Comparison, Outcome) format and the evidence profiles were produced. The literature review and recommendations were made according to the GRADE® Methodology. RESULTS The experts' work synthesis and the application of the GRADE method resulted in 19 recommendations. Among the recommendations formalised, 2 have a high level of evidence (GRADE 1+/-) and 12 have a low level of evidence (GRADE 2+/-). For 5 recommendations, the GRADE method could not be applied, resulting in expert advice. After two rounds of scoring and one amendment, strong agreement was reached on all the recommendations. CONCLUSIONS There was significant agreement among experts on strong recommendations to improve practices for the management of patients with spinal cord injury.

Abstract
AIM Nationwide data on the evolution of diabetes incidence and prevalence are scarce in France. For this reason, our objectives were to determine type 2 diabetes prevalence and incidence rates between 2010 and 2017, stratified by gender, age and region, and to assess annual time trends over the study period in adults aged≥45 years. METHODS Diabetes cases in the National Health Data System (SNDS), which covers the entire French population (66 million people), were identified through a validated algorithm. Gender- and age-specific prevalence and incidence rates were estimated. Negative binomial models, adjusted for gender, age and region, were used to assess annual time trends for prevalence and incidence throughout the study period. RESULTS During 2017, 3,144,225 diabetes cases aged≥45 years were identified. Over the study period, prevalence increased slightly (men from 11.5% to 12.1%, women from 7.9% to 8.4%) whereas incidence decreased (men from 11 to 9.7, women from 7.2 to 6.2 per 1000 person-years). In only four groups did prevalence rates decrease: men aged 45-65 years; women aged 45-60 years; women in Reunion; and women in Martinique. An increasing annual time trend was observed for prevalence (men: +0.9% [95% CI: +0.7%, +1%]; women: +0.4% [95% CI: +0.2%, +0.6%]) with a decreasing annual time trend for incidence in both genders (men: -2.6% [95% CI: -3.1%, -2.0%]; women: -3.9% [95% CI: -4.5%, -3.4%]). CONCLUSION Further efforts towards diabetes prevention are required to ensure that incidence rates in France continue to diminish, as the disorder continues to represent an important public-health burden.

Abstract
INTRODUCTION Pyogenic spondylodiscitis is a rare disease, but incidence is increasing. Reported failure rates following conservative management range from 12% to 18%. The purpose of this study was to determine the safety and efficacy of posterior percutaneous pedicle screw fixation combined with anterior debridement and fusion (ADF) for infective spondylodiscitis in the thoracic and/or lumbar spine. METHODS The retrospective study cohort comprised all patients without neurological deficit who underwent minimally invasive posterior and anterior surgery between April 2008 and April 2016 for thoracic and/or lumbar spondylodiscitis. RESULTS Forty patients were eligible (16 female: 40%). The lumbar region was affected in 31 cases (77.5%). Source of infection was identified in only 22 cases (55%) and bacteriological identification was obtained in 32 cases (80%). Mean hospital stay was 14.8 days (range, 6-39 days). Complete recovery was achieved in 39 patients (97.5%) at 3 months' follow-up. Mean preoperative local kyphosis angle was 16.1o, versus 14o at 1-year (P>0.05). 36 patients (90%) had at least 1 year's follow-up, and fusion was obtained for all these cases. CONCLUSION Two-stage minimally invasive surgery is effective and safe for the treatment of single or two-level thoracolumbar spondylodiscitis. It could be an alternative to conventional open surgery or conservative treatment.

Abstract
The current study aimed to analyze the relationships between students’ background variables (students’ academic preparation and sociocultural status), students’ cognitive and behavioral engagement, and an outcome variable (academic achievement). One sample of 380 first-year students who were studying in different scientific areas participated in the study. Students answered a questionnaire at the beginning and at the end of their first semester in college. To increase ecological validity, students’ cognitive and behavioral engagement and academic achievement were assessed using a specific curricular subject of the course as a reference. Students’ grades were collected through academic services. Data from both time points were analyzed with a structural equation model (SEM), and data showed a goodness of fit of SEM in both time points. Findings indicate that cognitive and behavioral engagement mediated the relationship between students’ background variables and their academic achievement. The analysis of both SEM allows us to understand that academic achievement at the end of the semester is closely related to what happens at the beginning of the semester (e.g., approach to learning, study time). Thus, promoting students’ engagement at the beginning of the semester should be considered a priority, as the first part of the first semester represents a critical period for students and for their integration in college. Thus, universities should consider improving their mechanisms of collecting information to allow for early identification, support, and monitoring of students at risk of dropping out, showing high level of disengagement and low academic achievement.

Abstract
SrTiO³ nanopowders doped with various percentages of Fe (0, 1, 3, and 5 mol%) was synthesized, determining its chemical and structural properties using X-ray diffraction and X-ray photoelectron spectroscopy. The magnetic properties of the samples were studied using hysteresis curves obtained by an alternating gradient magnetometer. Theoretical calculations within the framework of the density functional theory are also performed to support experimental data. The results indicated that Fe incorporated into de SrTiO³ structure induced intrinsic magnetic properties, which increase as the Fe percentage increase. At 5 mol% of Fe in the sample showed a single-domain state, typical of a ferromagnetic material capable for information storage. This latter result would be due to the reduction of oxygen vacancies as more Fe was added and to the presence of Fe2+ and Fe3+ ions reinforced the magnetic behaviour of the compound.

Abstract
BACKGROUND Owing to recent advances in cancer therapy, updated data are required for clinicians counselling patients on treatment of spinal metastases. OBJECTIVE To analyse the outcomes of surgical treatments of spinal metastases. METHODS Prospective and multicentric study that included consecutively patients operated on for spinal metastases between January 2016 and January 2017. Overall survival was calculated with the Kaplan-Meier method. Cox proportional hazard model was used to calculate hazard ratio (HR) analysing mortality risk according to preoperative Karnofsky performance status (KPS), mobility level and neurological status. RESULTS A total of 252 patients were included (145 males, 107 females) aged a mean 63.3 years. Median survival was 450 days. Primary cancer sites were lung (21%) and breast (19%). Multiple spinal metastases involved 122 patients (48%). Concomitant skeletal and visceral metastases were noted in 90 patients (36%). Main procedure was laminectomy and posterior fixation (57%). Overall, pain and mobility level were improved postoperatively. Most patients had normal preoperative motor function (50%) and remained so postoperatively. Patients "bedbound" on admission were the less likely to recover. In-hospital death rate was 2.4% (three disease progression, one septic shock, one pneumonia, one pulmonary embolism). Complication rate was 33%, deep wound infection was the most frequent aetiology. Higher mortality was observed in patients with poorest preoperative KPS (KPS 0-40%, HR = 3.1, p < 0.001) and mobility level ("bedbound", HR = 2.16, p < 0.001). Survival seemed also to be linked to preoperative neurological function. CONCLUSION Surgical treatments helped maintain reasonable condition for patients with spinal metastases. Intervention should be offered before patients' condition worsen to ensure better outcomes.

Abstract
Active hybrid microspheres were prepared by blending aqueous solutions of gelatine and chitosan with different concentrations of copper nanoparticles (0) (CuNPs) using emulsion-based crosslinking synthesis to obtain hybrid microspheres. The incorporation of CuNPs slightly affected the physical and chemical properties of the films. Microscopic surface structure (SEM), energy dispersive X-ray (EDX) spectroscopy and X-ray diffraction (XRD) analysis confirmed the presence of elemental copper and the crystalline structure of the CuNPs in the hybrid matrix. The surface properties of CuNPs were studied by XPS analyses. The antimicrobial activity of CuNPs coated with chitosan (QO)/gelatine (GE) compared to the QO/GE matrix alone was investigated, using the agar diffusion and culture medium methods in Mueller-Hinton. The evaluation was performed using the Gram-negative bacterium E. coli and the Gram positive bacterium E. faecalis. The investigated microspheres showed antimicrobial activity. Hybrid microspheres with 40 mg of Cu, evaluated in liquid medium, inhibited the growth of E. coli by 56% and of E. faecalis by 40% compared to the matrix hybridised alone; in solid medium, the inhibition was 2.5-fold and 2.6-fold, respectively. Thus, these microspheres are a promising material for applications with medical uses.

Abstract
BACKGROUND AND OBJECTIVES Advances in the field of three-dimensional scanning have enabled the development of instruments that can generate images that are useful in medicine. On the other hand, satisfaction studies are becoming increasingly important in the evaluation of quality in healthcare. We aimed to evaluate patients' and professionals' satisfaction with the use of a three-dimensional scanner applied to chest wall malformations. MATERIAL AND METHODS In the framework of a study to validate the results of three-dimensional scanning technology, we developed questionnaires to measure satisfaction among patients and professionals. We analyzed the results with descriptive statistics. RESULTS We included 42 patients and 10 professionals. Patients rated the speed and harmlessness positively; the mean overall level of satisfaction was 4.71 on a scale from 1 to 5. Among professionals, the level of satisfaction was lower, especially with regards to the treatment of the image; the mean overall level of satisfaction was 3.1. CONCLUSIONS Patients rated 3D scanning technology highly, but professionals were less satisfied due to the difficulty of treating the images and lack of familiarity with the system. For this technology to reach its maximum potential, it must be simplified and more widely disseminated.

Abstract
Students' writing constitutes a topic of major concern due to its importance in school and in daily life. To mitigate students' writing problems, school-based interventions have been implemented in the past, but there is still a need to examine the effectiveness of different types of writing interventions that use robust design methodologies. Hence, the present study followed a longitudinal cluster-randomized controlled design using a multilevel modeling analysis with 370 fourth-grade students (nested in 20 classes). The classes were randomly assigned to four conditions: one comparison group and three writing types of writing interventions (i.e., week-journals, Self-Regulation Strategy Development (SRSD) instruction and SRSD plus Self-Regulated Learning (SRL) program using a story-tool), with five classes participating in each condition. Data supports our hypothesis by showing differences between the treatment groups in students' writing quality over time. Globally, the improvement of students' writing quality throughout time is related to the level of specialization of the writing interventions implemented. This is an important finding with strong implications for educational practice. Week-journals and writing activities can be easily implemented in classrooms and provides an opportunity to promote students' writing quality. Still, students who participated in the instructional programs (i.e., SRSD and SRSD plus story-tool) exhibited higher writing quality than the students who wrote week-journals. Current data did not find statistical significant differences between results from the two instructional writing tools.

Abstract
BACKGROUND In case of cavernous sinus dural arteriovenous fistula, transvenous embolization of the cavernous sinus via the inferior petrosal sinus is generally sufficient. However, when inferior petrosal sinus access is challenging, various alternative approaches have been reported, with corresponding difficulties and risks. CASE REPORTS We report the management of two cases of life-threatening cavernous sinus dural arteriovenous fistula revealed by a typical cavernous sinus syndrome. Conventional approaches were unsuccessful, and a direct microsurgical approach was performed, with catheterization of the superior ophthalmic vein. This combined approach safely accessed the cavernous sinus, and obtained complete occlusion of the fistulae by Onyx® embolization. CONCLUSIONS This procedure could be an interesting alternative option in the treatment of cavernous sinus dural arteriovenous fistula when conventional approaches are not possible.

Abstract
The case under review is a 60-year-old patient with a vertebral plasmocytoma treated by cervico-thoracic fusion 2 years previously. He presented a thoracic spinal septic non-union complicated by esophagospinal fistula. We performed vascularized fibula transplant with cutaneous pad to fill the esophageal fistula. Control CT at day 5 confirmed vascular anastomosis permeability and bone transplant position. Osseointegration was achieved at 18 months postoperatively. The patient was alive 3 years after the last procedure (5 years after tumorectomy). A systematic review of the literature on spinal reconstruction by vascularized fibula transplant showed the diversity of surgical techniques available. In view of the multiplicity of possible organ and soft tissue defects involving the spine, reminders are provided of the different approaches and recipient vessels in this type of reconstruction depending on location.

Abstract
INTRODUCTION Circumferential fusion for lumbar low-grade isthmic spondylolisthesis (LGIS) provides the best spinal stability and highest fusion rates. The aim of this study is to investigate results of minimal invasive management of LGIS and correlations between Intervertebral Foramen Surface (IFS) and other parameters. METHODS We retrospectively reviewed cases of 43 patients who underwent a minimally invasive circumferential fusion (Anterior lumbar interbody fusion followed by percutaneous posterior pedicle screw fixation) for LGIS between January 2010 and December 2014 in our institution. Inclusion criteria were one-level (L4-L5 or L5-S1) LGIS with low back and/or radicular pain. Pre- and postoperative radiographic evaluations were performed at 6, 12 and 24months. Measurements (Percentage of anterior displacement, degree of slip angle, height of the intervertebral space and the IFS) were obtained using Surgimap®. RESULTS Nineteen patients (44.2%) were males. Mean age was 43 years old (19-72years). The mean follow-up of the series was 18.3months (3-72months). Mean preoperative Visual Analogy Scale (VAS) for low back pain decreased from 70mm to 20mm and from 80mm to 10mm as to radicular pain. Anterior displacement was reduced from 18% to 7% (p<0.01), degree of slippage were increased from 9.8° to 15.2° (p<0.01), intervertebral height was restored from 4.4mm to 8.5mm (p<0.01) and increase of the IFS was calculated 48.8%. CONCLUSION One stage circumferential fixation for adults' LGIS without decompression, allows restoration of intervertebral height permitting good reduction of the slippage, an increasing of the IFS and liberation of nerve roots.

Abstract
INTRODUCTION The short-term results of endoscopic treatment of vesicoureteral reflux (VUR) are excellent. Over time, however, a number of patients have been identified for whom VUR reappeared after being resolved with this technique. The aim of this study was to analyse the factors related to this event. MATERIAL AND METHODS A retrospective, analytical, case-control study included 395 ureteral units with primary VUR treated successfully at our centre, with a minimum follow-up of 3 years. We identified cases in which VUR reappeared and analysed the demographic variables, those related to VUR (grade, laterality, initial study) and those related to the operation (materials used). RESULTS We identified 77 ureteral units with recurrence in the 395 included units (19.5%). The recurrence rate was 29.7% for the patients treated with dextranomer/hyaluronic acid (Dx/HA), 20.2% for those treated with polydimethylsiloxane (MP) and 12.2% for polytetrafluoroethylene (PTFE). The onset of recurrence rose to 35% for patients treated before 1 year of age and those with gradeV VUR. Urinary dysfunction symptoms also increased the recurrence rate to 34.9%. CONCLUSION The use of resorbable dextranomer/hyaluronic acid material was related to recurrence in the endoscopic treatment of VUR. The high-grade reflux and treatment at an early age, as well as the presence of urinary dysfunction, are also factors associated with recurrence.

Abstract
INTRODUCTION Currarino's syndrome (CS) is an autosomal dominant disorder of embryonic development causing a rare malformating syndrome characterized by a triad of an anorectal malformations, presacral mass (most commonly an anterior sacral meningocele) and sacral bony defects. Mutations of the HLXB9 gene have been identified in most CS cases, but a precise genotype-phenotype correlation has not been described so far. Family screening is obligatory. The diagnosis is usually made during childhood and rarely in adulthood. In this context, imaging, and especially MRI plays a major role in the diagnosis of this syndrome. Surgical management is provided by pediatric surgeons or neurosurgeons. FAMILIAL CASE REPORT Here, we present a family case report with CS requiring different neurosurgical management. The son, a 3-year-old boy, developed a tethered spinal cord syndrome associated to a lipoma of the filum terminale, a sacro-coccygeal teratoma and an anal adhesion. A combined surgical approach permitted a good evolution on the urinary and digestive functions despite a persistent fecal incontinence. The 2-year-old daughter presented with a cyst of the thyreoglossal tract infected and fistulized to the skin. She was also followed for a very small lipoma of the filum terminale that required a neurosurgical approach. The father, 44-year-old, manifested functional digestive and urinary disorders caused by a giant anterior sacral meningocele. The ligation of the neck of the cyst and aspiration of the liquid inside in full through a posterior partial approach permit a complete collapse of the cyst with an instantly satisfactory clinical outcome. CONCLUSION In these cases, cooperation between pediatric surgeons and neurosurgeons was crucial. The follow-up of these patients should be done in a spina bifida clinic. A geneticist evaluation must be offered to the patient in the case of a CS as well as a clinical evaluation of the relatives (parents, siblings).

Abstract
INTRODUCTION Adjacent level spondylodiscitis (ALS) after primary surgery for thoracic spondylodiscitis is a very rare condition. CASE REPORT We report the case of a 76-year-old man with this pathology. A first posterior minimally invasive approach combined with anterior approach to the thoracic spine was safely performed for thoracic spondylodiscitis. More than a year later, exploration of recurrent symptoms with 18FDG PET scan helped to diagnose ALS. Further surgery was performed. At 3-year follow-up examination showed no recurrence of the infection. DISCUSSION ALS should be suspected during recurrent symptoms after spinal fusion surgery. Evaluation should be based on the results of 18FDG PET scan and surgery. CONCLUSION Bacterial and histopathological analyses combined with an increase of spine fixation and adapted antimicrobial therapy are a safe management for ALS.

Abstract
BACKGROUND The risk of vertebral fracture is increased 4-fold in patients with ankylosing spondylitis (AS). Diagnostic challenges and the vulnerability associated with AS combine to generate high morbidity and mortality rates. The objective of this study was to assess the outcome of percutaneous thoraco-lumbar fracture surgery in patients with AS, in terms of quality of life, fracture healing, and complications. HYPOTHESIS Percutaneous surgery used to treat thoraco-lumbar fractures in patients with AS reliably provides fracture healing, preserves self-sufficiency, and minimises post-operative complications. METHODS Two centres included 31 patients with AS who were managed by percutaneous surgery for thoraco-lumbar fractures in 2013-2015. The data were reviewed retrospectively, although admission data were collected prospectively. Clinical outcomes were assessed by comparing the values at baseline and last follow-up of three variables: the Parker score, the visual analogue scale (VAS) pain score, and the EuroQol five dimensions (EQ-5D) quality-of-life score. Computed tomography was performed 1 year after surgery to evaluate bone healing, screw position, and implant loosening. Intra- and post-operative complications were recorded. RESULTS The 31 patients had a mean age at surgery of 75.1 years, a mean follow-up of 35.6 months, and a minimum follow-up of 12 months. Three patients died during follow-up. Mean hospital stay duration was 6 days. Cemented screw fixation was used in 18 patients. At last follow-up, all patients had recovered their self-sufficiency; the mean Parker score was 7.14, compared to 6.73 at baseline, the mean VAS pain score was 1.8, and the mean EQ-5D score decrease versus baseline was 0.07 (P=0.02). Bone healing was consistently achieved. Loosening of an uncemented pedicle screw was noted in 1 patient. Of the 228 screws implanted, 6 (2.6%) were improperly positioned, including 1 within the spinal canal in a patient free of neurological manifestations. Asymptomatic cement leakage was noted in 2 patients. DISCUSSION Percutaneous fixation of thoraco-lumbar fractures in patients with AS is a reliable method that produces a high healing rate and allows prompt patient mobilisation with preservation of self-sufficiency. The post-operative complication rate is low. LEVEL OF EVIDENCE IV, retrospective observational study.

Abstract
BACKGROUND Odontoid fractures are the most common upper cervical spine fracture in adults over 70 years of age. Hence, treatment of these fractures has public health implications. OBJECTIVES Evaluate the early complications, bone healing and mortality in patients above 75 years of age who undergo surgical treatment of an odontoid fracture. Compare the results between patients operated with the Harms technique or anterior screw fixation. METHODS This was a retrospective study of 70 patients with an odontoid fracture who were treated surgically between 2000 and 2015 at the Hôpital de la Timone in France. The age at the time of diagnosis, comorbidities, ASA score and autonomy were evaluated. Bone healing was determined using computed tomography. RESULTS In the cohort, 22 patients underwent anterior screw fixation, 38 were treated using the Harms technique and 10 with other procedures. The average age was 85.1 years. Fifty-four percent of patients had an ASA score above 3. The average follow-up was 23.4 months. An Anderson type II fracture was present in 80.6% of patients. In the anterior screw fixation group, the operative time was significantly shorter than in the Harms group and no blood transfusions were needed. However, 13.6% of these patients had to be re-operated because the initial construct was unstable; no patients in the Harms group underwent revision surgery. There were more complications in the anterior screw fixation group than in the Harms group: 41% versus 13.2% (P<0.02). The fractures had healed in all patients reviewed after 1 year. The 3-month survival in the anterior screw fixation group was 64.7% and it was 81.3% in the Harms group. These rates were stable at 1 year with no statistical differences between groups. CONCLUSION Surgical treatment of odontoid fractures in the elderly results in an excellent union rate. The mortality rate is stable after 3 months. In our experience, the Harms technique has a lower risk of complications and better mechanical stability than anterior screw fixation. Despite the steep learning curve, we believe the Harms technique is probably the best choice for treating odontoid fractures in the elderly. LEVEL OF EVIDENCE IV.

Abstract
PURPOSE Report the results of surgical treatment of post-traumatic atlantoaxial rotatory fixation (AARF) due to C2 articular facet fracture in adults. MATERIAL AND METHODS The records of five patients treated since 2009 for AARF due to a C2 articular facet fracture were analyzed retrospectively. Three women and two men with an average age of 60 years (27-82) were included, one of whom initially had neurological deficits. In all cases, the surgical strategy consisted of posterior fixation: Harms-type in four cases and trans-articular with hooks in one case. RESULTS Dislocations due to fracture of the C2 articular facet are rare in adults; various treatment strategies have been described. In our experience, posterior screw fixation leads to satisfactory clinical and radiological outcomes. Fusion is not necessary in these cases because the dislocation is related to an asymmetric fracture without ligament damage. CONCLUSION Posterior fixation provides satisfactory reduction of these injuries and leads to satisfactory bone union. This surgical treatment can be performed early on after the trauma and is an interesting alternative to conservative treatment.
