Translation and validation of the Vietnamese Epilepsy Self-Management Scale (V-ESMS).

OBJECTIVES: This study aimed to translate and validate the Vietnamese version of the Epilepsy Self-Management Scale (V-ESMS). METHODS: The translation and cross-cultural adaptation of the original version of the ESMS into Vietnamese followed the Principles of Good Practice for the Translation and Cultural Adaptation Process for Patient-Reported Outcomes Measures guideline with "forward-backward" translation and culturally adapted. The participants were recruited consecutively at neurology clinics at Nguyen Tri Phuong Hospital and University Medical Center, Ho Chi Minh City, from January 2022 to July 2022 and required to complete the V-ESMS. The validity was assessed by exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Cronbach's alpha and intraclass correlation coefficient (ICC) were used to evaluate internal and temporal reliability, respectively. RESULTS: A total of 200 participants were recruited for analysis. The V-ESMS included 36 items and five domains. The factor loading ranged between 0.313 and 0.927; most items loaded in their hypothesized factors proved in the original scale. Using the CFA, theCMIN/DF, comparative fit index, and root mean square error of approximation were 2.883, 0.80, and 0.097, respectively. The Cronbach's alpha in each domain was 0.79-0.907; the scale was 0.936. The ICC from 0.94 to 0.98 showed excellent test-retest reliability. CONCLUSION: The 36-item V-ESMS with five domains presented good validity and reliability. This instrument could be used to assess self-management in people with epilepsy in Vietnam.

Influence of Posture on Gait Parameters in Severe Symptomatic Lumbar Stenosis Before and After Decompression Surgery.

BACKGROUND: We searched to quantify the influence of sagittal vertical axis (SVA) on the improvement of spatiotemporal gait parameters using a gait motion analysis (GMA) before and after decompression surgery in patients suffering from lumbar spinal stenosis (LSS). METHODS: Thirty-nine patients with severe LisSS planned for lumbar decompression underwent a full-body biplanar radiographs (EOS) to quantify the SVA and have benefited from a 3-dimensional GMA 1 month before surgery (M0) and 6 month (M6) after surgery. The first step of this study was to confirm the validation of 3-dimensional sagittal vertical axis (3D SVA) for posture analysis. An analysis of modification of the 3D SVA and spatiotemporal gait parameters was then carried out in order to identify any correlation. RESULTS: Decompression surgery did not significantly improve 3D SVA between M0 and M6 (respectively 49.1 [50.3] vs. 49.84 [19.02], P = 0.42). Concerning spatiotemporal parameters, we found significant difference for all parameters between M0 and M6. A strong correlation (R2 > 0.65) between static SVA (EOS) and 3D SVA was demonstrated using a statistical regression equation. There was also a statistically significant correlation between SVA (static and 3-dimension) and improvement in spatiotemporal gait parameters after decompression surgery. CONCLUSIONS: This study analyses the relationship between postural change (SVA) and improvement in gait parameters measured during GMA before and after decompression surgery for LSS. This specific analysis of gait parameters may represent a prognostic assessment tool for the recovery of patients undergoing surgery for a LSS.

Mental Health Among Healthcare Workers During the COVID-19 Pandemic in Vietnam.

OBJECTIVES: The objective of this study was to characterize mental health issues among Vietnamese healthcare workers (HCWs) and to identify related factors. METHODS: A cross-sectional study was conducted with 990 HCWs in 2021. Their mental health status was measured using the Depression, Anxiety, and Stress Scale. RESULTS: In total, 49.9%, 52.3%, and 29.8% of respondents were found to have depression, anxiety, and stress, respectively. The multivariable linear regression model revealed that factors associated with increased anxiety scores included depression scores (ß, 0.45; 95% confidence interval [CI], 0.39 to 0.51) and stress scores (ß, 0.46; 95% CI, 0.41 to 0.52). Factors associated with increased depression scores included being frontline HCWs (ß, 0.57; 95% CI, 0.10 to 1.10), stress scores (ß, 0.50; 95% CI, 0.45 to 0.56), and anxiety scores (ß, 0.41; 95% CI, 0.36 to 0.47), while working experience was associated with reduced depression scores (ß, -0.08; 95% CI, -0.16 to -0.01). Factors associated with increased stress scores included working experience (ß, 0.08; 95% CI, 0.00 to 0.16), personal protective equipment interference with daily activities (ß, 0.55; 95% CI, 0.07 to 1.00), depression scores (ß, 0.54; 95% CI, 0.48 to 0.59), and anxiety scores (ß, 0.45; 95% CI, 0.39 to 0.50), while age was associated with reduced stress scores (ß, -0.12; 95% CI, -0.20 to -0.05). CONCLUSIONS: Specific interventions are necessary to enhance and promote the mental health of HCWs so they can successfully cope with the circumstances of the pandemic.

Intradural extramedullary metastasis of oncocytic carcinoma of the parotid gland: A first case report and review of the literature.

We present an extremely infrequent case of intradural metastasis of a parotid tumour, responsible for motor deficit in legs. To our knowledge, this is the first reported case of an intradural metastasis of a malignant and rare parotid tumour, oncocytic carcinoma. It accounts for less than 1% of salivary gland tumours. Its management is not codified and its prognosis seems to be poor. Local recurrences are common, as are regional metastases. Distant metastases are present in less than 30% of cases and are poorly described, mainly involving the lung. Thanks to the surgical treatment, our patient has partially recovered his motor and sensory functions.

Sleep Quality and Poor Sleep-related Factors Among Healthcare Workers During the COVID-19 Pandemic in Vietnam.

OBJECTIVES: The coronavirus disease 2019 (COVID-19) pandemic has increased the workload of healthcare workers (HCWs), impacting their health. This study aimed to assess sleep quality using the Pittsburgh Sleep Quality Index (PSQI) and identify factors associated with poor sleep among HCWs in Vietnam during the COVID-19 pandemic. METHODS: In this cross-sectional study, 1000 frontline HCWs were recruited from various healthcare facilities in Vietnam between October 2021 and November 2021. Data were collected using a 3-part self-administered questionnaire, which covered demographics, sleep quality, and factors related to poor sleep. Poor sleep quality was defined as a total PSQI score of 5 or higher. RESULTS: Participants' mean age was 33.20±6.81 years (range, 20.0-61.0), and 63.0% were women. The median work experience was 8.54±6.30 years. Approximately 6.3% had chronic comorbidities, such as hypertension and diabetes mellitus. About 59.5% were directly responsible for patient care and treatment, while 7.1% worked in tracing and sampling. A total of 73.8% reported poor sleep quality. Multivariate logistic regression revealed significant associations between poor sleep quality and the presence of chronic comorbidities (odds ratio [OR], 2.34; 95% confidence interval [CI], 1.17 to 5.24), being a frontline HCW directly involved in patient care and treatment (OR, 1.59; 95% CI, 1.16 to 2.16), increased working hours (OR, 1.84; 95% CI,1.37 to 2.48), and a higher frequency of encountering critically ill and dying patients (OR, 1.42; 95% CI, 1.03 to 1.95). CONCLUSIONS: The high prevalence of poor sleep among HCWs in Vietnam during the COVID-19 pandemic was similar to that in other countries. Working conditions should be adjusted to improve sleep quality among this population.

In vivo evaluation of Adipose-Derived Stem Cells (ADSCs) using Nanofat technique and chitosan conduit for peripheral nerve defect repair.

INTRODUCTION: Nerve autograft is the gold standard for reconstruction of peripheral nerve loss. The alternative is the interposition of a synthetic regeneration conduit. The purpose of the study was to evaluate the in vivo feasibility and interest of Adipose-Derived Stem Cells (ADSCs) using the Nanofat technique and chitosan conduit for peripheral nerve defect repair. MATERIAL AND METHODS: In vivo, after the creation of a 10 mm defect of the sciatic nerve, 2 groups were defined according to the nerve repair in rats: "chitosan" group (n = 10) and "chitosan and ADSCs" group (n = 10) with a clinical and paraclinical evaluation at 7 weeks. RESULTS: The in vivo results seem to show that the adjunction of ADSCs was favorable clinically, histologically and functionally compare to a chitosan reconstruction alone. DISCUSSION: Peripheral nerve repair with defect using a chitosan conduit associated with ADSCs would constitute a surgical alternative in a single surgical step.

Respective roles of Pik3ca mutations and cyproterone acetate impregnation in mouse meningioma tumorigenesis.

Despite their rarity, PIK3CA mutations in meningiomas have raised interest as potentially targetable, ubiquitous mutations owing to their presence in sporadic benign and malignant tumors but also in hormone-related cases. Using new genetically engineered mouse models, we here demonstrate that Pik3ca mutations in postnatal meningeal cells are sufficient to promote meningioma formation but also tumor progression in mice. Conversely, hormone impregnation, whether alone or in association with Pik3ca and Nf2 mutations, fails to induce meningioma tumorigenesis while promoting breast tumor formation. We then confirm in vitro the effect of Pik3ca mutations but not hormone impregnation on the proliferation of primary cultures of mouse meningeal cells. Finally, we show by exome analysis of breast tumors and meninges that hormone impregnation promotes breast tumor formation without additional somatic oncogenic mutation but is associated with an increased mutational burden on Pik3ca-mutant background. Taken together, these results tend to suggest a prominent role of Pik3ca mutations over hormone impregnation in meningioma tumorigenesis, the exact effect of the latter is still to be discovered.

Pituitary Abscess: A Challenging Preoperative Diagnosis-A Multicenter Study.

Background and Objectives: Pituitary abscess (PA) is a rare occurrence, representing less than 1% of pituitary lesions, and is defined by the presence of an infected purulent collection within the sella turcica. Pas can be classified as either primary, when the underlying pituitary is normal prior to infection, or secondary, when there is associated a pre-existing sellar pathology (i.e., pituitary adenoma, Rathke's cleft cysts, or craniopharyngioma), with or without a recent history of surgery. Preoperative diagnosis, owing to both non-specific symptoms and imaging features, remains challenging. Treatment options include endonasal trans-sphenoidal pus evacuation, as well as culture and tailored antibiotic therapy. Methods: A retrospective multicenter study, conducted on a prospectively built database over a 20-year period, identified a large series of 84 patients harboring primary sellar abscess. The study aimed to identify crucial clinical and imaging features in order to accelerate appropriate management. Results: The most common clinical presentation was a symptom triad consisting of various degrees of asthenia (75%), visual impairment (71%), and headache (50%). Diagnosis was achieved in 95% of cases peri- or postoperatively. Functional recovery was good for visual disturbances and headache. Pituitary function recovery remained very poor (23%), whereas the preoperative diagnosis represented a protective factor. Conclusions: In light of the high prevalence of pituitary dysfunction following the management of PAs, early diagnosis and treatment might represent a crucial issue. Currently, there are no standard investigations to establish a conclusive preoperative diagnosis; however, new, emerging imaging methods, in particular nuclear imaging modalities, represent a very promising tool, whose potential warrants further investigations.

Surgical morbidity of the extradural anterior petrosal approach: the Lariboisière experience.

OBJECTIVE: Concerns about the approach-related morbidity of the extradural anterior petrosal approach (EAPA) have been raised, especially regarding temporal lobe and venous injuries, hearing impairment, facial nerve palsy, cerebrospinal fluid fistula, and seizures. There is lack in the literature of studies with detailed analysis of surgical complications. The authors have presented a large series of patients who were treated with EAPA, focusing on complications and their avoidance. METHODS: The authors carried out a retrospective review of patients who underwent EAPA at their institution between 2012 and 2021. They collected preoperative clinical characteristics, operative reports, operative videos, findings on neuroimaging, histological diagnosis, postoperative course, and clinical status at last follow-up. For pathologies without petrous bone invasion, the amount of petrous apex drilling was calculated and classified as low (< 70% of the volume) or high (≥ 70%). Complications were dichotomized as approach related and resection related. RESULTS: This study included 49 patients: 26 with meningiomas, 10 brainstem cavernomas, 4 chondrosarcomas, 4 chordomas, 2 schwannomas, 1 epidermoid cyst, 1 cholesterol granuloma, and 1 osteoblastoma. The most common approach-related complications were temporal lobe injury (6.1% of patients), seizures (6.1%), pseudomeningocele (6.1%), hearing impairment (4.1%), and dry eye (4.1%). Approach-related complications occurred most commonly in patients with a meningioma (p = 0.02) and Meckel's cave invasion (p = 0.02). Gross-total or near-total resection was correlated with a higher rate of tumor resection-related complications (p = 0.02) but not approach-related complications (p = 0.76). Inferior, lateral, and superior tumoral extension were not correlated with a higher rate of tumor resection-related complications. No correlation was found between high amount of petrous bone drilling and approach- or resection-related complications. CONCLUSIONS: EAPA is a challenging approach that deals with critical neurovascular structures and demands specific skills to be safely performed. Contrary to general belief, its approach-related morbidity seems to be acceptable at dedicated skull base centers. Morbidity can be lowered with careful examination of the preoperative neuroradiological workup, appropriate patient selection, and attention to technical details.

Violence and non-fatal injuries among Vietnamese in-school adolescents: national prevalence estimates and associated factors.

School violence and injury are major public health problems worldwide. The data of this study were from the Viet Nam Global School-based Student Health Survey (GSHS) - a nationally representative survey conducted in 2019, with a sample size of 7690 students aged 13-17 years old. We found the prevalence of violence and non-fatal injury to be 14.5% and 21.4%, respectively. Factors related to higher odds of violence and non-fatal injuries in both sexes included smoking cigarettes, drinking alcohol, having mental health problems (loneliness, worrying and suicidal thinking), and truancy. In contrast, parental monitoring was associated with lower odds of violence, and parental respect was a protective factor of both violence and non-fatal injuries. Students who experienced violence had a higher likelihood of having non-fatal injuries in both sexes. Future policies should consider individual factors and parent-child bonding, to mitigate the burden of violence and injury among in-school adolescents in Viet Nam.

Atypical evolution of meningiomatosis after discontinuation of cyproterone acetate: clinical cases and histomolecular characterization.

PURPOSE: The long-term use of cyproterone acetate (CPA) is associated with an increased risk of developing intracranial meningiomas. CPA discontinuation most often induces a stabilization or regression of the tumor. The underlying biological mechanisms as well as the reasons why some meningiomas still grow after CPA discontinuation remain unknown. We reported a series of patients presenting CPA-induced meningiomatosis with opposed tumor evolutions following CPA discontinuation, highlighting the underlying histological and genetic features. METHODS: Patients presenting several meningiomas with opposite tumor evolution (coexistence of growing and shrinking tumors) following CPA discontinuation were identified. Clinical and radiological data were reviewed. A retrospective volumetric analysis of the meningiomas was performed. All the growing meningiomas were operated. Each operated tumor was characterized by histological and genetic analyses. RESULTS: Four women with multiple meningiomas and opposite tumor volume evolutions after CPA discontinuation were identified. Histopathological analysis characterized the convexity and tentorial tumors which continued to grow after CPA discontinuation as fibroblastic meningiomas. The decreasing skull base tumor was characterized as a fibroblastic meningioma with increased fibrosis and a widespread collagen formation. The two growing skull base meningiomas were identified as meningothelial and transitional meningiomas. The molecular characterization found two NF2 mutations among the growing meningiomas and a PIK3CA mutation in the skull base tumor which decreased. CONCLUSION: To our knowledge, this is the first report describing an atypical tumor evolution of CPA-associated meningiomas after CPA discontinuation. The underlying biological mechanisms explaining this observation and especially the close relationship between mutational landscapes and embryologic origins of the meninges in CPA-related meningiomas as well as their clonal origin require further research.

Somatic PIK3CA Mutations in Sporadic Cerebral Cavernous Malformations.

BACKGROUND: Cerebral cavernous malformations (CCMs) are common sporadic and inherited vascular malformations of the central nervous system. Although familial CCMs are linked to loss-of-function mutations in KRIT1 (CCM1), CCM2, or PDCD10 (CCM3), the genetic cause of sporadic CCMs, representing 80% of cases, remains incompletely understood. METHODS: We developed two mouse models harboring mutations identified in human meningiomas with the use of the prostaglandin D2 synthase (PGDS) promoter. We performed targeted DNA sequencing of surgically resected CCMs from patients and confirmed our findings by droplet digital polymerase-chain-reaction analysis. RESULTS: We found that in mice expressing one of two common genetic drivers of meningioma - Pik3ca H1047R or AKT1 E17K - in PGDS-positive cells, a spectrum of typical CCMs develops (in 22% and 11% of the mice, respectively) instead of meningiomas, which prompted us to analyze tissue samples from sporadic CCMs from 88 patients. We detected somatic activating PIK3CA and AKT1 mutations in 39% and 1%, respectively, of lesion tissue from the patients. Only 10% of lesions harbored mutations in the CCM genes. We analyzed lesions induced by the activating mutations Pik3ca H1074R and AKT1 E17K in mice and identified the PGDS-expressing pericyte as the probable cell of origin. CONCLUSIONS: In tissue samples from sporadic CCMs, mutations in PIK3CA were represented to a greater extent than mutations in any other gene. The contribution of somatic mutations in the genes that cause familial CCMs was comparatively small. (Funded by the Fondation ARC pour la Recherche contre le Cancer and others.).

Multimodal management of surgery- and radiation-refractory meningiomas: an analysis of the French national tumor board meeting on meningiomas cohort.

PURPOSE: Meningiomas represent the most frequent tumor of the central nervous system in adults. While most meningiomas are efficiently treated by surgery and radiotherapy/radiosurgery, there is a small portion of radiation- and surgery-refractory tumors for which there is no clear recommendation for optimal management. The French National Tumor Board Meeting on Meningiomas (NTBM) offers a glimpse on the current management of such patients. METHODS: We retrospectively reviewed the charts of patients presented to the multidisciplinary Meeting between 2016 and 2019. We selected patients with a progressive disease after at least two treatments, including surgery and radiotherapy. RESULTS: In this multicentric cohort of 86 cases, patients harbored 17 (19.8%) WHO Grade I, 48 (55.8%) WHO Grade II and 21 (24.4%) WHO Grade III tumors. The median number of treatments received before inclusion was 3 (range: 2 - 11). Following the Board Meeting, 32 patients (37.2%) received chemotherapy, 11 (12.8%) surgery, 17 (19.8%) radiotherapy, 14 (16.3%) watchful observation and 12 (13.9%) palliative care. After a mean follow-up of 13 months post-inclusion, 32 patients (37.2%) had died from their disease. The mean progression free survival was 27 months after radiotherapy, 10 months after surgery, 8.5 months after chemotherapy (Bevacizumab: 9 months - Octreotide/Everolimus: 8 months). CONCLUSIONS: Surgery- and radiation-refractory meningiomas represent a heterogeneous group of tumors with a majority of WHO Grade II cases. If re-irradiation and redo-surgery are not possible, bevacizumab and octreotide-everolimus appear as a valuable option in heavily pre-treated patients considering the current EANO guidelines.

Investigation of Mechanical, Chemical, and Antibacterial Properties of Electrospun Cellulose-Based Scaffolds Containing Orange Essential Oil and Silver Nanoparticles.

This study demonstrated a controllable release properties and synergistic antibacterial actions between orange essential oil (OEO) and silver nanoparticles (AgNPs) incorporated onto cellulose (CL) nanofibers. The preparation of AgNPs attached on CL nanofibers was conducted through multiple processes including the deacetylation process to transform cellulose acetate (CA) nanofibers to CL nanofibers, the in situ synthesis of AgNPs, and the coating of as-prepared silver composite CL nanofibers using OEO solutions with two different concentrations. The success of immobilization of AgNPs onto the surface of CL nanofibers and the incorporation of OEO into the polymer matrix was confirmed by SEM-EDS, TEM, XRD, and FT-IR characterizations. The tensile strength, elongation at break, and Young's modulus of the nanofibers after each step of treatment were recorded and compared to pristine CA nanofibers. The high antibacterial activities of AgNPs and OEO were assessed against Gram-positive B. subtilis and Gram-negative E. coli microorganisms. The combined effects of two antimicrobials, AgNPs and OEO, were distinctively recognized against E. coli.

Surgical Site Infections after glioblastoma surgery: results of a multicentric retrospective study.

BACKGROUND: The effects of surgical site infections (SSI) after glioblastoma surgery on patient outcomes are understudied. The aim of this retrospective multicenter study was to evaluate the impact of SSI on the survival of glioblastoma patients. METHODS: Data from SSI cases after glioblastoma surgeries between 2009 and 2016 were collected from 14 French neurosurgical centers. Collected data included patient demographics, previous medical history, risk factors, details of the surgical procedure, radiotherapy/chemotherapy, infection characteristics, and infection management. Similar data were collected from gender- and age-paired control individuals. RESULTS: We used the medical records of 77 SSI patients and 58 control individuals. 13 were excluded. Our analyses included data from 64 SSI cases and 58 non-infected glioblastoma patients. Infections occurred after surgery for primary tumors in 38 cases (group I) and after surgery for a recurrent tumor in 26 cases (group II). Median survival was 381, 633, and 547 days in patients of group I, group II, and the control group, respectively. Patients in group I had significantly shorter survival compared to the other two groups (p < 0.05). The one-year survival rate of patients who developed infections after surgery for primary tumors was 50%. Additionally, we found that SSIs led to postoperative treatment discontinuation in 30% of the patients. DISCUSSION: Our findings highlighted the severity of SSIs after glioblastoma surgery, as they significantly affect patient survival. The establishment of preventive measures, as well as guidelines for the management of SSIs, is of high clinical importance.

Rare Complication of Percutaneous Technique: Intradural Cement Leakage and Its Surgical Treatment.

Popularity of percutaneous vertebroplasty and vertebral augmentation to treat vertebral compression fractures is increasing. Cement leakages are relatively common, but intradural cement leakage is rare. Few cases of intradural cement leakage have been reported in the literature, and emergency surgery has been reported to be <1%. A 64-year-old man with osteolytic vertebral compression fracture at L1, caused by a malignant tumor, had undergone a vertebral augmentation by craniocaudal procedure. Neurologic examination after the surgery revealed paralysis in both legs immediately postoperatively. Computed tomographic imaging revealed a large cement leakage into the spinal canal. The patient was referred to our department for emergency management. He was rapidly scheduled for surgical decompression by laminectomy. First, stabilization by a secure posterior short fixation was done. The laminectomy showed that insertion of a needle through the pedicle had breached the dura and had caused intradural cement leakage. As shown in the Supplementary Video, the piece of intradural cement was finally removed after posterior durotomy. This case demonstrates that even if percutaneous vertebroplasty is a relatively safe technique, it should be performed by well-trained physicians and with great care to prevent disabling complications.

Quality of antiepileptic drugs in Vietnam.

The purpose of this research was to evaluate the quality of anti-epileptic drugs (AEDs) in a central city of South Vietnam. A cross-sectional study was conducted in all the outlets for AEDs. Out of 33 pharmacies 54% had AEDs. Where the drugs were available, 89% of the pharmacies, 10 units were purchased, choosing the cheapest ones. The information on the packaging, the galenic form and the aspect of the drug were studied. Each sample's tablet was weighted and was considered satisfactory if it was within +/-10% of the average. A HPLC method was used for dosing the active ingredient (AI), which was considered satisfactory within +/-10% of the theoretical value. Eight samples were based on carbamazepin and eight on phenytoin. None of the 16 samples collected were past their expiring date. Tablets were homogeneous in shape, dimension and color. The uniformity of weight was satisfactory but the AI results were alarming for Carbamazepin and more often for Phenytoin. Only 35% of the tablets were correctly dosed. Because of differences of sensitivities of AEDs to storage conditions, environmental factors (heat, light and humidity) could be responsible for this result. Best results were achieved in structures where storage seemed to be better. The influence of storage conditions must be further studied to confirm this conclusion.
