Abstract
Valproic acid is an effective treatment for generalized seizure and related neurological defects. Despite its efficacy and acceptability, its use is associated with adverse drug effects. Moringa oleifera leaves are rich in phytochemical and nutritional components. It has excellent antioxidant and ethnobotanical benefits, thus popular among folk medicines and nutraceuticals. In the present study, 70% ethanol extract of moringa leaves was assessed for its in vivo biochemical and histological effects against valproate-induced kidney damage. Female Sprague-Dawley rats were randomly divided into four groups: Group I: control animals given physiological saline (n = 8); Group II: Moringa extract-administered group (0.3 g/kg b.w./day, n = 8); Group III: valproate-administered animals (0.5 g/kg b.w./day, n = 15); and Group IV: valproate + moringa extract (given similar doses of both valproate and moringa extract, n = 12) administered group. Treatments were administered orally for 15 days, the animals were fasted overnight, anesthetized, and then tissue samples harvested. In the valproate-administered experimental group, serum urea and uric acid were elevated. In the kidney tissue of the valproate rats, glutathione was depleted, antioxidant enzyme activities (superoxide dismutase, catalase, glutathione reductase, glutathione S-transferase, and glutathione peroxidase) disrupted, while oxidative stress biomarker, inflammatory proteins (Tumor necrosis factor-alpha and interleukin-6), histological damage scores, and the number of PCNA-positive cells were elevated. M. oleifera attenuated all these biochemical defects through its plethora of diverse antioxidant and therapeutic properties.

Leandro-Merhi VA, de Almeida Souza Tedrus GM, Jacober de Moraes GG, Ravelli MN. Interaction between vitamin D level, antiseizure medications (ASM) and seizure control in epilepsy adult patients. Rev Neurol (Paris) 2023; 179:1111-1117. [PMID: 37758540 DOI: 10.1016/j.neurol.2023.04.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2022] [Revised: 04/09/2023] [Accepted: 04/12/2023] [Indexed: 09/29/2023]
Abstract
OBJECTIVE To investigate vitamin D levels and factors associated with seizure control in adult patients with epilepsy (APE). METHOD Cross-sectional study with APE in routine outpatient follow-up at a neurology clinic. Clinical variables, antiseizure medications (ASM) and vitamin D were investigated. Data were analyzed using the Chi2 or Fisher's exact tests, Mann-Whitney, Spearman's correlation coefficient, ROC curve and univariate and multiple logistic regression analysis. RESULTS Mean age was 46.5±15.1 years and disease duration was 27.5±17.0 years; 52.7% (n=49) of patients used one ASM and 47.3% (n=44) used≥2 ASM. There was a significant difference in the level of vitamin D according to the number of ASM and it was higher in patients who used a single ASM (26.02±10.22 versus 22.50±8.69; P=0.048). In the logistic regression, when vitamin D level was set at 20ng/mL, the chance of seizure control for patients using a single ASM was 6.99 times greater than for those using≥2 ASM. When vitamin D level was set at 40ng/mL, the number of ASM did not modify seizure control. There was no correlation between vitamin D and disease duration, patient age and age at the time of the first seizure. In the logistic regression, it was observed that satisfactory levels of vitamin D did not modify potential seizure control. CONCLUSION Thirty-three percent (33%) of patients presented with vitamin D deficiency (values below 20ng/mL) and 80% had vitamin D levels below what is recommended (30ng/mL). The use of ASM, when associated with different levels of vitamin D, modified the probability of seizure control in APE. Vitamin D levels and intrinsic epilepsy factors are associated with failure to effectively control seizures.

Abstract
Introduction Objective: to assess the occurrence of overweight/obesity in patient with epilepsy (PWEs) and to relate it to cognitive aspects and clinical variables. Methodology: the measurements of waist circumference, calf circumference, arm circumference, and the body mass index were related to the scores of the Mini-Mental State Examination and the Brief Cognitive Battery-Edu, as well as to the clinical variables of 164 PWEs, with a significance level of p < 0.05. Data were compared to a similar control group (CG) comprising 71 cases. Linear and multiple logistic regression models were used to assess factors related to cognitive aspects. Results: the mean age of the PWEs was 49.8 ± 16.6 years with a mean length of epilepsy of 22 ± 15.9 years. Overweight/obesity occurred in 106 (64.6 %) PWEs and in 42 (59.1 %) CG subjects. The PWEs had a worse performance in several cognitive functions when compared to CG subjects. In the PWEs, overweight/obesity was associated with lower educational level, older age, and cognitive impairment. Greater waist circumference, overweight, age at the first seizure, and use of polytherapy with antiseizure medications were predictive factors of memory impairment in multiple linear regression. Greater arm and calf circumference values were associated with better performance in several cognitive areas. Conclusion: the occurrence of overweight/obesity in PWEs and CG subjects was high. Cognitive impairment occurred in a high number of PWEs and was associated with overweight, greater waist circumference values, and clinical aspects of epilepsy. Better cognitive performance was associated with greater arm and calf circumference.

Abstract
OBJECTIVE Studies have shown that obesity has a significant impact on poor surgical outcomes. However, the relationship between obesity and pediatric epilepsy surgery has not been reported. This study aimed to explore the relationship between obesity and complications of pediatric epilepsy surgery and the effect of obesity on the outcome of pediatric epilepsy surgery, and to provide a reference for weight management of children with epilepsy. METHODS A single-center retrospective analysis of complications in children undergoing epilepsy surgery was conducted. Body mass index (BMI) percentiles were adjusted by age and used as a criterion for assessing obesity in children. According to the adjusted BMI value, the children were divided into the obese group (n = 16) and nonobese group (n = 20). The intraoperative blood loss, operation time, and postoperative fever were compared between the two groups. RESULTS A total of 36 children were included in the study, including 20 girls and 16 boys. The mean age of the children was 8.0 years old, ranging from 0.8 to 16.9 years old. The mean BMI was 18.1 kg/m2, ranging from 12.4 kg/m2 to 28.3 kg/m2. Sixteen of them were overweight or obese (44.4%). Obesity was associated with higher intraoperative blood loss in children with epilepsy (p = 0.04), and there was no correlation between obesity and operation time (p = 0.21). Obese children had a greater risk of postoperative fever (56.3%) than nonobese children (55.0%), but this was statistically nonsignificant (p = 0.61). The long-term follow-up outcomes showed that 23 patients (63.9%) were seizure-free (Engel grade I), 6 patients (16.7%) had Engel grade II, and 7 patients (19.4%) had Engel grade III. There was no difference in long-term seizure control outcomes between obese and nonobese groups (p = 0.682). There were no permanent neurological complications after surgery. CONCLUSION Compared with nonobese children with epilepsy, obese children with epilepsy had a higher intraoperative blood loss. It is necessary to conduct early weight management of children with epilepsy as long as possible.

Abstract
Glioblastoma multiforme (GBM) is a malignant primary tumor type of the central nervous system (CNS). This type of brain tumor is rare and is responsible for 12-15% of all brain tumors. The typical survival rate of GBM is only 12 to 14 months. GBM has a poor and unsatisfactory prognosis despite advances in research and therapeutic interventions via neurosurgery, radiation, and chemotherapy. The molecular heterogeneity, aggressive nature, and occurrence of drug-resistant cancer stem cells in GB restricts the therapeutic efficacy. Interestingly, the CNS tumors in children are the second most usual and persistent type of solid tumor. Since numerous research studies has shown the association between obesity and cancer, childhood obesity is one of the potential reasons behind the development of CNS tumors, including GBM. Obesity in children has almost reached epidemic rates in both developed and developing countries, harming children's physical and mental health. Obese children are more likely to face obesity as adults and develop non-communicable diseases such as diabetes and cardiovascular disease as compared to adults with normal weight. However, the actual origin and cause of obesity are difficult to be pointed out, as it is assumed to be a disorder with numerous causes such as environmental factors, lifestyle, and cultural background. In this narrative review article, we discuss the various molecular and genetic drivers of obesity that can be targeted as potential contributing factors to fight the development of GBM in children.

Abstract
Drug-resistant epilepsy occurs in 25-30% of patients. Furthermore, treatment with a first-generation antiseizure drug (ASD) fails in 30-40% of individuals because of their intolerable adverse effects. Over the past three decades, 20 newer- (second- and third-)generation ASDs with unique mechanisms of action and pharmacokinetic profiles have been introduced into clinical practice. This advent has expanded the therapeutic armamentarium of epilepsy and broadens the choices of ASDs to match the individual patient's characteristics. In recent years, research has been focused on defining the ASD of choice for different seizure types. In 2017, the International League Against Epilepsy published a new classification for seizure types and epilepsy syndrome. This classification has been of paramount importance to accurately classify the patient's seizure type(s) and prescribe the ASD that is appropriate. A year later, the American Academy of Neurology published a new guideline for ASD selection in adult and pediatric patients with new-onset and treatment-resistant epilepsy. The guideline primarily relied on studies that compare the first-generation and second-generation ASDs, with limited data for the efficacy of third-generation drugs. While researchers have been called for investigating those drugs in future research, epilepsy specialists may wish to share their personal experiences to support the treatment guidelines. Given the rapid advances in the development of ASDs in recent years and the continuous updates in definitions, classifications, and treatment guidelines for seizure types and epilepsy syndromes, this review aims to present a complete overview of the current state of the literature about the efficacy and tolerability of ASDs and provide guidance to clinicians about selecting appropriate ASDs for initial treatment of epilepsy according to different seizure types and epilepsy syndromes based on the current literature and recent US and UK practical guidelines.

Abstract
BACKGROUND Antiseizure drugs (ASDs) are the primary therapy for epilepsy, with more than 20 drugs introduced into clinical practice to date. These drugs are typically grouped by their mechanisms of action and therapeutic spectrum. This article aims to educate non-neurologists and medical students about the new frontiers in the pharmacology of ASDs and presents the current state of the literature on the efficacy and tolerability of these agents. METHODS Randomized controlled trials, observational studies, and evidence-based meta-analyses of ASD efficacy and tolerability as initial monotherapy for epileptic seizures and syndromes were identified in PubMed, EMBASE, the Cochrane Library, and Elsevier Clinical Pharmacology. RESULTS The choice of ASD varies primarily according to the seizure type. Practical guidelines for ASD selection in patients with new-onset and drug-resistant epilepsy were recently published. The guidelines have shown that the newer-generation drugs, which have unique mechanistic and pharmacokinetic properties, are better tolerated but have similar efficacy compared with the older drugs. Several ASDs are effective as first-line monotherapy in focal seizures, including lamotrigine, carbamazepine, phenytoin, levetiracetam, and zonisamide. Valproate remains the first-line drug for many patients with generalized and unclassified epilepsies. However, valproate should be avoided, if possible, in women of childbearing potential because of teratogenicity. Toxicity profile precludes several drugs from use as first-line treatment, for example, vigabatrin, felbamate, and rufinamide. CONCLUSIONS Antiseizure drugs have different pharmacologic profiles that should be considered when selecting and prescribing these agents for epilepsy. These include pharmacokinetic properties, propensity for drug-drug interactions, and adverse effects.

Abstract
Obesity is a chronic, multifactorial disease associated with a large number of comorbidities. The clinical management of obesity involves a stepwise integrated approach, beginning with behavioral and lifestyle modification, followed by antiobesity medications, endobariatric procedures, and bariatric surgery. Weight gain and subsequent obesity are common side effects of medications, such as prednisone or antipsychotics. In this era of precision medicine, it is essential to identify patients at the highest risk of weight gain as a result of medication use. Pharmacogenomics could play an important role in obesity management by optimizing use of antiobesity medications as well as minimizing adverse weight gain. This review aims to provide a comprehensive analysis of the current literature on the role of pharmacogenomics in obesity and medication-induced weight gain. In summary, there are more robust studies of medication associated with weight gain and pharmacogenomics, and more studies are needed to understand the role of pharmacogenomics in antiobesity medications.

Abstract
Fucus vesiculosus is often incorporated in weight loss dietary supplements to improve weight loss in overweight adults. Obesity is a common condition in epilepsy patients and is indeed increasing in refractory epilepsy and in patients under polytherapy. Since lamotrigine (LTG) is a first-line antiepileptic drug, used in monotherapy or adjunctive therapy, the main objective of this work was to investigate the potential pharmacokinetic-based interactions between F. vesiculosus and LTG in rats. In a first pharmacokinetic study, a single oral dose of F. vesiculosus extract (575 mg/kg, p.o.) was co-administered with a single-dose of LTG (10 mg/kg, p.o.). In a second study, rats were orally pretreated with F. vesiculosus extract (575 mg/kg/day, p.o.) for 14 days and received LTG (10 mg/kg, p.o.) on the 15th day. In the control groups, rats received water instead of the extract. After LTG administration, blood samples were taken until 96 h post-dose, and LTG concentrations measured in plasma were submitted to a non-compartmental pharmacokinetic analysis. The co-administration of F. vesiculosus extract and LTG caused no significant changes in the drug kinetics. However, the repeated pretreatment with F. vesiculosus extract significantly reduced the peak concentrations of LTG and caused a slightly decrease in the extent of systemic drug exposure. Overall, based on these results, no significant clinical impact is expected from the administration of F. vesiculosus dietary supplements and LTG.

Abstract
BACKGROUND Association of obesity, quality of life (QoL), and physical fitness in people with epilepsy (PWE) is rarely reported. We evaluate the effect of a 12-week home-based exercise program on weight reduction and physical capacity in PWE. METHODS In 173 PWE, physical fitness was assessed by using six-minute walk test (6MWT) and one-minute step test. Self-reported QoL data was collected using a 12-Item Short Form Survey (SF-12) questionnaire; further physical (PCS) and mental (MCS) component scores were derived. Effect of exercise was evaluated using randomized study of 110 PWE, divided into control and exercise groups of 55 each. RESULTS At baseline, mean age of study population was 25.85 ± 9.62 years with 77 (44.5%) women. Average body mass index (BMI) was 29.33 ± 6.17 kg/m2. Mean PCS and MCS were 45.95 ± 7.92 and 45.72 ± 10.40 respectively. In 124 (71.7%) PWE with obesity, while high-density lipoprotein (HDL-C) (46.10 ± 12.32 vs. 39.30 ± 10.39 mg/dL; p < .001) was lower, low-density lipoprotein (LDL-C) (101.60 ± 37.51 vs. 113.89 ± 32.65 mg/dL; p = .035) was high. Both the randomized groups were comparable for type and number of antiepileptic drugs (AEDs) used. At 12-week follow-up, PWE in the exercise group reduced 7.65 ± 5.62 kg while control group gained an average of 4.01 ± 4.74 kg (p < .001). Distance walked in 6MWT (293.07 ± 118.73 vs. 464.29 ± 55.33 m; p = .007) and PCS (48.59 ± 8.57 vs. 52.62 ± 4.03; p = .006) were higher in exercise group whereas MCS did not differ between the groups. None of the participants reported seizure during the 12-week follow-up period. CONCLUSION People with epilepsy have low PCS and MCS scores; PWE with obesity have altered metabolic profile when compared to PWE without obesity. A 12-week, home-based exercise program significantly reduces weight and improves physical capacity, irrespective of AEDs used. Trials with larger sample size and longer follow-up are required to validate our findings.

Abstract
There are many angles to consider in drug treatment of obese patients. On the one hand, some specific weight loss drugs are available, on the other, several drugs are associated with unintentional weight changes. When treating an obese patient for any given disease, several physiological changes may influence the pharmacokinetic properties of the drugs required. Thus, increased body weight may influence the efficacy and safety of some drug treatments. Even more complicated is the situation after weight reduction surgery. Due to the various changes to the gastrointestinal tract induced by the different surgical techniques used, and the dynamic changes in body composition thereafter, drug dosing has to be constantly reconsidered. Whereas all of these issues are of clinical importance, none of them have been investigated in the necessary depth and broadness to ensure safe and efficacious drug treatment of the massively obese patient. Individual considerations have to be based on comorbidities, concomitant medication, and on specific drug properties, for example, lipophilicity, volume of distribution, and metabolism. In this article we summarize the data available on different aspects of drug treatment in the obese patient with the hope of improving patient care.

Abstract
The review includes studies on the association between the use of VA drugs and weight gain in patients with epilepsy as well as other valproate-induced adverse drug reactions, including insulin resistance. Understanding the mechanisms of significant weight gain of patients taking VA drugs will help personalize antiepileptic therapy and minimize the risk of valproate-induced obesity.

Abstract
Epilepsy affects all age groups and is one of the most common and most disabling neurological disorders. The accurate diagnosis of seizures is essential as some patients will be misdiagnosed with epilepsy, whereas others will receive an incorrect diagnosis. Indeed, errors in diagnosis are common, and many patients fail to receive the correct treatment, which often has severe consequences. Although many patients have seizure control using a single medication, others require multiple medications, resective surgery, neuromodulation devices or dietary therapies. In addition, one-third of patients will continue to have uncontrolled seizures. Epilepsy can substantially impair quality of life owing to seizures, comorbid mood and psychiatric disorders, cognitive deficits and adverse effects of medications. In addition, seizures can be fatal owing to direct effects on autonomic and arousal functions or owing to indirect effects such as drowning and other accidents. Deciphering the pathophysiology of epilepsy has advanced the understanding of the cellular and molecular events initiated by pathogenetic insults that transform normal circuits into epileptic circuits (epileptogenesis) and the mechanisms that generate seizures (ictogenesis). The discovery of >500 genes associated with epilepsy has led to new animal models, more precise diagnoses and, in some cases, targeted therapies.

Abstract
The combination of obesity and pain may worsen a patient's functional status and quality of life more than each condition in isolation. We systematically searched PubMed/MEDLINE and the Cochrane databases for all reports published on obesity and pain. The prevalence of combined obesity and pain was substantial. Good evidence shows that weight reduction can alleviate pain and diminish pain-related functional impairment. However, inadequate pain control can be a barrier to effective lifestyle modification and rehabilitation. This article examines specific pain management approaches for obese patients and reviews novel interventional techniques for treatment of obesity. The infrastructure for simultaneous treatment of obesity and pain already exists in pain medicine (eg, patient education, behavioral medicine approaches, physical rehabilitation, medications, and interventional treatment). Screening for obesity, pain-related disability, and behavioral disorders as well as monitoring of functional performance should become routine in pain medicine practices. Such an approach requires additional physician and staff training. Further research should focus on better understanding the interplay between these 2 very common conditions and the development of effective treatment strategies.

Abstract
OBJECTIVES Ketogenic diet (KD) is an important therapy used in the control of drug-refractory seizures. The major goal of this review is to update the knowledge about the adverse effects of KD on lipoproteins, lipid profile, and cardiometabolic risk. METHODS Articles on the effect of the KD on plasma lipoproteins of children and adolescents with refractory epilepsy, which were published in the past 15 years and indexed in the PubMed and MedLine databases, were included. RESULTS Dyslipidemia was recurrent in children, and adolescents treated with KD. Evidence suggests that hypercholesterolemia promotes structural modifications in low-density lipoprotein particles. Such modifications possibly favor oxidative processes and contribute to changes in the size of lipoproteins, particularly related to small and denser LDL. However, oxidative modifications in LDL of children on KD are not described in the literature. DISCUSSION The positive effects of KD on the health of children and adolescents with refractory epilepsy are unquestionable. Conversely, this positive role is associated with significant and negative changes in lipid metabolism. Moreover, the positive effects are possibly related to oxidative reactions and unbalance of antioxidants that can contribute to an increased cardiometabolic risk. Therefore, this review invites clinicians and researchers to investigate the lipid and oxidative metabolism in their clinical practice and trials, respectively.

Abstract
OBJECTIVE In the general population, obesity is associated with accelerated age-related cognitive decline. The impact of obesity on cognitive function in neurological populations who already have a heightened risk of cognitive decline is unknown. This study explored the relationship between obesity and cognitive underfunction in people with medically intractable epilepsy. METHODS Eighty-one consecutive patients admitted for evaluation for medically intractable epilepsy (36 females and 45 males) underwent tests of memory and intellectual function. Optimal level of function was assessed using the National Adult Reading Test - Revised. Measures of underfunction were calculated by subtracting current measures of intellectual ability from the NART IQ. Body mass index (BMI) was used as an index of obesity. RESULTS Twenty-nine people had a BMI in the healthy range (36%), 31 were overweight (38%), and 21 were obese (26%). The healthy weight, overweight, and obese groups did not differ in age at the time of assessment, age at seizure onset, or optimal level of function (NART IQ). The obese group had a greater degree of suboptimal processing speed and demonstrated a greater degree of underfunction on the Full Scale IQ (FSIQ) measure compared to the healthy weight group. Body mass index accounted for 14% of the variance in underfunction in processing speed and 10% of the variance in underfunction in FSIQ. Controlling for the effects of age, all measures of memory function were significantly correlated with BMI, with poorer scores associated with higher BMIs. SIGNIFICANCE A small but significant proportion of the variance in memory function and intellectual underfunction in people with epilepsy is explained by BMI. Further work is needed to establish whether a reduction in BMI to within healthy limits is associated with improvements in cognitive function in this group.
