Abstract
Sexual and gender minority (LGBT+) people face unique health disparities that must be considered by health-care providers to ensure equitable and inclusive care. Although traditionally LGBT+ health has not been integrated into neurology training, sexual orientation and gender identity have direct relevance to neurological health, driven by both systemic and interpersonal factors. In this Review, we summarize the evidence for associations between sexual orientation and gender identity with the prevalence and outcomes of various neurological conditions, including neurodegenerative diseases, epilepsy, stroke and neurodevelopmental disorders, among others. We describe important clinical considerations pertaining to LGBT+ people and recommend language and practices to promote inclusive care, as well as highlight gaps in need of further research and possible strategies to minimize these, including systematic collection of sexual orientation and gender identity and use of inclusive language.

Abstract
Fertility treatment, including assisted reproductive technology (ART), is increasingly used. Sex hormones influence seizure control as well as interacting with antiseizure medications, and so the hormonal manipulation involved in fertility treatments has direct implications for people with epilepsy. Here, we summarise the various fertility treatments and consider their important influences on epilepsy care. While early observations raised concerns about seizure exacerbation associated with ART, there are limited data to guide best practice in people with epilepsy, and further research is needed.

Abstract
Canadian women of reproductive potential living with epilepsy present unique care challenges due to the complex interplay of hormones, seizures, and medications. This study explores reproductive health practices and counselling for women with epilepsy. Through a questionnaire developed by the Canadian League Against Epilepsy women with epilepsy (WWE) workgroup, we are the first to report demographic and real-world practice characteristics of Canadian healthcare professionals providing care for WWE with specific focus on family planning, birth plans, and postpartum care counselling. Among respondents, 76.9% routinely reviewed contraception with patients and an intrauterine device (IUD) was the most popular recommended method (85.3%). With regards to preconception planning, 50% of respondents routinely had a preconception drug level prior to pregnancy. A significant proportion, 44.9%, reported not communicating a neurology-informed birth plan to obstetrical health practitioners. The majority recommended breastfeeding for WWE on anti-seizure medications (92.3%) and regularly provided safety counselling for women in the postpartum period (84.6%). Overall, our study demonstrates that Canadian practice patterns conform reasonably well to existing evidence and guidelines, although important gaps in care exist.

Patterns of psychotropic medication prescribing and potential drug-hormone interactions among transgender and gender-diverse adults within 2 years of hormone therapy. J Am Pharm Assoc (2003) 2024; 64:283-289.e2. [PMID: 37839699 PMCID: PMC10873097 DOI: 10.1016/j.japh.2023.10.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2023] [Revised: 10/07/2023] [Accepted: 10/09/2023] [Indexed: 10/17/2023]
Abstract
BACKGROUND Transgender and gender-diverse (TGD) people have a high prevalence of psychotropic medication use, yet knowledge about the patient-level psychotropic medication burden is limited. TGD patients may take hormone therapy to meet their gender expression goals. Potential drug-hormone interactions exist between psychotropic medications and hormone therapy, requiring increased knowledge about psychotropic medication use for TGD adults undergoing hormone therapy. OBJECTIVES The objective of this study was to examine the extent of psychotropic medication polypharmacy in a cohort of TGD adults within 2 years of starting hormone therapy. We also characterized potential drug-hormone interactions and the association with psychotropic polypharmacy. METHODS Retrospective cross-sectional analysis of patients with ≥1 transgender health-related visit (2007-2017) in the University of Washington Medical System (Seattle, WA). Eligible patients had ≥1 psychotropic medication including antidepressants, antipsychotics, mood stabilizers, and sedative-hypnotics ordered within 2 years of starting hormone therapy (testosterone or estradiol with or without spironolactone, progesterone, finasteride, or dutasteride). We defined psychotropic polypharmacy as ≥2 psychotropic medication orders with overlapping treatment durations for at least 90 days and characterized potential drug-hormone interactions (Lexicomp, Hudson, OH). We descriptively summarized patients with and without polypharmacy (frequencies and percentages) and compared drug-hormone interactions using chi-square or Fishers exact tests (P < 0.05 considered significant). RESULTS A total of 184 patients had ≥1 psychotropic medication order within 2 years of hormone therapy; 68 patients (37.0%) had psychotropic polypharmacy. The most frequent type of psychotropic polypharmacy was antidepressant+sedative-hypnotic (18 of 68, 26.5%). More patients had a potential drug-hormone interaction among those with psychotropic polypharmacy (23 of 68, 33.8%) versus those without (8 of 116, 6.9%, P < 0.001). CONCLUSION Among TGD patients on psychotropic medications within 2 years of hormone therapy, one-third had psychotropic polypharmacy. Most polypharmacy types appeared to align with mental health treatment guidelines. The number of patients with a potential drug-hormone interaction was significantly higher among those with polypharmacy. Prospective studies are needed to characterize drug-hormone interactions.

Abstract
Background Previous studies have highlighted instances where pharmacists lacked knowledge regarding women's health issues related to epilepsy. Objectives To assess UAE community pharmacists' knowledge, toward women's issues in epilepsy. Methods a cross-sectional research method was employed. A team of seven pharmacy students in their final year visited a randomly selected sample of community pharmacies in the UAE and face-to-face interviews were conducted with the pharmacists using a structured questionnaire. The questionnaire includes two parts; Eight questions designed to elicit data about the demographics of the study participants and 12 questions eliciting insights into the participants' knowledge of women's issues in epilepsy. Results A total of 412 community pharmacist were recruited in the study. The overall level of knowledge about women's issues in epilepsy was good and the average knowledge score was 81% with a 95% confidence interval (CI) [79.1, 82.7%]. The results of multivariate analysis showed higher knowledge scores in chain pharmacies (OR 1.37; 95% CI 1.12-1.67), Chief pharmacists (OR 1.44; 95% CI 1.01-2.06), Pharmacists in charge (OR 3.46; 95% CI 2.7-4.45), pharmacists with 1-5 Years of experience (OR 2.87; 95% CI 1.71-4.82), pharmacists with 6-10 Years (OR 2.63; 95% CI 1.58-4.38), pharmacists with >10 years (OR 3.13; 95% CI 2.03-4.83), graduation form regional universities (OR 1.37; 95% CI 1.12-1.67), graduation form international universities (OR 1.73; 95% CI 1.36-2.20) and receiving a training on epilepsy (OR 1.36; 95% CI 1.12-1.67). Conclusion While the findings reveal an overall promising level of knowledge among community pharmacists regarding the issues faced by women with epilepsy, pinpointing which clinical and demographic factors have the most significant impact on this knowledge would permit the implementation of tailored educational interventions. Workshops and modules targeting the issues faced by women with epilepsy would further raise the knowledge and competence among community pharmacists in this area, ensuring better pharmaceutical care for this population.

Neurology 2023; 101:e1083-e1096. [PMID: 37407266 PMCID: PMC10491435 DOI: 10.1212/wnl.0000000000207580] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2022] [Accepted: 05/10/2023] [Indexed: 07/07/2023] Open
Abstract
BACKGROUND AND OBJECTIVES Antiseizure medications (ASMs) are among the most commonly prescribed teratogenic drugs in women of childbearing age. Limited data exist on utilization patterns across different indications for therapy and for the newer-generation ASMs in this population. Thus, we assessed the pattern of ASM use in women of childbearing age with epilepsy and nonepilepsy indications (pain and psychiatric disorders). METHODS We conducted a retrospective analysis of deidentified administrative data submitted to the Optum Clinformatics database. Eligible participants included women aged 12-50 years who filled ASMs between year 2011 and 2017. Participants were followed from date of index prescription filled to study end or insurance disenrollment, whichever came first. For the overall cohort and potential therapy indications, we assessed the type and frequency of ASMs filled; proportion of participants on monotherapy, polytherapy, or treatment switching; and duration of continuous use. Trends were characterized using annual percent change from study start to study end. RESULTS Our analysis included 465,131 participants who filled 603,916 distinct ASM prescriptions. At baseline, most of the participants had chronic pain (51.0%) and psychiatric disorders (32.7%), with epilepsy the least common (0.9%). The most frequently dispensed were diazepam (24.3%), lorazepam (20.1%), gabapentin (17.4%), clonazepam (12.7%), topiramate (11.3%), and lamotrigine (4.6%). Significant linear increase in trends were observed with gabapentin (annual percent change [95% CI]: 8.4 [7.3-9.4]; p < 0.001) and levetiracetam (3.4 [0.7-6.2]; p = 0.022) and decreasing trends for diazepam (-3.5 [-2.4 to 4.5]; p < 0.001) and clonazepam (-3.4 [-2.3 to 4.5]; p = 0.001). No significant change in trend was observed with valproate (-0.4 [-2.7 to 1.9]; p = 0.651), while nonlinear changes in trends were observed with lorazepam, topiramate, lamotrigine, and pregabalin. DISCUSSION Decreasing trends were observed with older ASMs in the overall cohort and across the potential indications for therapy. Conversely, increasing trends were seen with the newer ASMs. Considering the risk of teratogenicity associated with the newer medications largely unknown, counseling and education in addition to a careful consideration of the benefits vs potential risks should remain pivotal when prescribing ASMs for women of childbearing age.

Abstract
Objective This study is aimed at comparing differential effect of Levetiracetam (LTC) monotherapy and Carbamazepine (CZP) monotherapy in W omen with epilepsy (WWE) on gonadal hormone. Methods 87 WWE were recruited comprising randomly of 46 and 41 on CZP and LTC group respectively with diagnosis and classification based on International League Against Epilepsy (ILAE). Reproductive hormones (Luteinizing Hormone (LH), Follicle stimulating hormone, progesterone, estradiol and testosterone) were assayed. National Hospital Seizure Severity Scale (NHSS) and Zung self-reporting depression scale (ZSRDS) were used to assess the seizure severity and the mood respectively. Data was analyzed using Statistical Package for Social Sciences (SPSS) version 20. The Chi-square test was used to compare categorical variables while Student's t-test or its non-parametric equivalent where appropriate were used to compare continuous variables. Results Clinical characteristics were comparable in both groups except for ZSRDS (p = 0.048), NHSS (p = 0.012) and hip circumference (p = 0.037). The CZP group had a higher ASEX score and proportion of WWE with clinically significant sexual dysfunction (p < 0.001). WWE on LTC had similar hormonal profiles with those on CZP except for a higher median serum testosterone level (p = 0.004), and lower median serum LH (p = 0.006). Age was negatively associated with serum testosterone level for the 25th, 50th, and 75th quartile. However, the differential effect for AED type was only significant for the 25th quartile; with higher values in LTC. Conclusion The therapeutics implication of lower LH and testosterone levels in the LTC group compared to CZP group need to be explored.

Epilepsy Behav 2023; 142:109205.

Abstract
Unlike several epilepsies with onset in pediatric age, adult-onset epilepsies do not typically have a time course that is predictably self-remitting in the large majority of people. Still, about one-half of individuals with adult-onset epilepsy who have been seizure-free for an extended period (two years or longer) on antiseizure medications (ASMs) will remain in remission when their drug therapy is discontinued. Although a number of predictors of outcome have been identified (including specific adult-onset syndromes associated with a low probability of spontaneous remission), in most cases, the only way to establish whether the epilepsy has remitted in a given individual is to gradually withdraw ASMs. ASM withdrawal can be beneficial, particularly when the currently used treatment is not well tolerated, or could lead to adverse outcomes in the future (i.e., teratogenic effects should pregnancy occur in a female of childbearing potential). However, the risks associated with ASM withdrawal are significant. Relapse of seizures can have major adverse psychosocial consequences and also may carry a risk of morbidity and mortality. Most importantly, evidence suggests that in about 20% of individuals whose seizure relapsed following ASM withdrawal, re-institution of pharmacological therapy may not readily restore seizure control. Ultimately, management decisions should prioritize the preference of the well-informed person with epilepsy. Particularly, when adverse drug effects are a concern, options to be discussed should include not only withdrawal or continuation of the current treatment but also dose reduction or substitution with a different ASM.

Abstract
Management of seizures often involves continuous medication use throughout a patient's life, including when a patient is pregnant. The physiological changes during pregnancy can lead to altered drug exposure to anti-seizure medications, increasing patient response variability. In addition, subtherapeutic anti-seizure medication concentrations in the mother may increase seizure frequency, raising the risk of miscarriage and preterm labor. On the other hand, drug exposure increases can lead to differences in neurodevelopmental outcomes in the developing fetus. Established pregnancy registries provide insight into the teratogenicity potential of anti-seizure medication use. In addition, some anti-seizure medications are associated with an increased risk of major congenital malformations, and their use has declined over the last decade. Although newer anti-seizure medications are thought to have more favorable pharmacokinetics in general, they are not without risk, as they may undergo significant pharmacokinetic changes when an individual becomes pregnant. With known changes in metabolism and kidney function during pregnancy, therapeutic monitoring of drug concentrations helps to determine if and when doses should be changed to maintain similar seizure control as observed pre-pregnancy. This review concentrates on the results from research in the past decade (2010-2022) regarding risks of major congenital malformations, changes in prescribing patterns, and pharmacokinetics of the anti-seizure medications that are prescribed to pregnant patients with epilepsy.

Abstract
Sex and gender differences in epilepsy are important influencing factors in epilepsy care. In epilepsy, the hormonal differences between the sexes are important as they impact specific treatment considerations for patients at various life stages particularly during early adulthood with establishment of the menstrual cycle, pregnancy, perimenopause and menopause. Choice of antiseizure medication may have direct consequences on hormonal cycles, hormonal contraception, pregnancy and fetal risk of major congenital malformation. Conversely hormones whether intrinsic or extrinsically administered may have direct impact on antiseizure medications and seizure control. This chapter explores these important influences on the management of persons with epilepsy.

Abstract
Youth with intellectual and developmental disabilities (I/DD) are impacted by pubertal changes and the onset of menses disproportionately. Despite the fact that for most youth with I/DD, the progression of puberty, menarche, and irregular cycles due to axis immaturity appear to be consistent with the general population, cyclic behavioral changes and premenstrual symptoms may be more common. Furthermore, for some disabled youth there are endocrine or medication effects that may impact menses disproportionately. Education and access to care is essential for this group to address many aspects of treatment, from prepubertal anticipatory guidance to menstrual management, with special attention required for addressing issues concerning hygiene, cyclic pain, behavior changes, sexuality, potential for abuse, and pregnancy prevention.1-4 This article will provide an overview of the policies and guidance available for management of the menstrual issues encountered in adolescents with intellectual and developmental disabilities and complex medical disorders. Included will be a review of studies that evaluate the different types of methods that are utilized for menstrual management and the different conditions that are encountered.

Abstract
We planned this experimental study to investigate the effect of carbamazepine (CMZ) on the endometriotic implants. Rats were randomised into four groups after endometriosis surgery. Drinking water was given to the sham group, 0.2 mg/kg oestradiol valerate (EV) to the EV group, 100 mg/kg/day CMZ to the CMZ group, and 0.2 mg/kg EV and 100 mg/kg/day CMZ to the EV-CMZ group. The endometrium of the rats using CMZ stained more intensely with cytochrome P450-3A4 (CYP3A4) enzyme. No endometrial hyperplasia was found in these rats. Endometriotic implants weight was found to be higher in these rats. There was no difference between the groups in terms of staining of the endometriotic implants with CYP3A4 enzyme. Endometriotic implants were less stained with the CYP3A4 enzyme than the endometrium. According to our results, CMZ does not increase the destruction of oestrogen in the endometriotic implants, unlike the endometrium. It may even cause the lesion to enlarge.Impact statementWhat is already known on this subject? Endometriosis is an oestrogen-dependent, progressive disease. Carbamazepine (CMZ) is known to increase oestrogen degradation by activating the cytochrome P450-3A4 (CYP3A4) enzyme. CMZ can be used in the treatment of endometriosis because it increases oestrogen breakdown in tissues.What do the results of this study add? CMZ can protect the endometrium against hyperplasia by increasing the amount of CYP3A4 enzyme in the endometrium. This effect could not be demonstrated in the endometriotic implants. The presence of CYP3A4 enzyme less in the endometriotic implants than in the endometrium may explain this situation. In addition, the fact that CMZ does not increase the enzyme in the endometriotic implants may contribute to this situation.What are the implications of these findings for clinical practice and/or further research? CMZ may not be a suitable alternative in the treatment of endometriosis. However, it may protect against endometrial hyperplasia. Clinical studies are needed for this effect.

Abstract
BACKGROUND Counseling adolescent women with epilepsy (WWE) about reproductive health (contraception, sexual activity, and menstruation) is important given the teratogenicity of many antiseizure medications and high rates of contraception failure. Only a third of adolescent WWE report discussing contraception with their epileptologists, demonstrating a significant gap in counseling. METHODS We assessed factors associated with reproductive health counseling by pediatric neurologists via a retrospective chart review of adolescent (aged 12-18 years) WWE seen at a pediatric neurology clinic from 2018 to 2020. RESULTS We analyzed 219 visits among 89 unique WWE. There were 23 documented discussions on contraception (11% of visits), 8 on sexual activity (4%), and 127 on menstruation (58%). When contraception was discussed, sexual activity and menstruation were more frequently discussed. Female providers were more likely to document a discussion of menstruation (OR = 3.2, 95% CI = [1.6, 6.4]). WWE who were older at the time of visit or who had their first seizure at an older age were more likely to have documented discussions of contraception and sexual activity. Neither details of treatment regimen nor epilepsy type was associated with documentation of counseling. CONCLUSIONS A minority of adolescent WWE have documented reproductive health discussions, demonstrating a need for quality improvement projects to address this gap in care.

Abstract
PURPOSE OF REVIEW Issues pertaining to women with epilepsy have advanced with a better understanding of multidirectional influences among hormones, seizures, and antiseizure medications, as well as pregnancy-related concerns around fertility, seizure destabilization, and antiseizure medication-associated teratogenicity. This article highlights important developments in this field and reviews best practices in the management of women with epilepsy. RECENT FINDINGS Important external hormonal influences may impact women with epilepsy particularly in the context of gender-affirming medications, hormonal replacement therapy, and fertility therapies. Fertility for women with epilepsy is influenced by multiple variables; however, in the absence of preexisting fertility issues, epilepsy per se is not associated with significantly impaired fertility. Once women with epilepsy are pregnant, the majority have a stable course. Antiseizure medication use in pregnancy is associated with major congenital malformations 2 to 5 times that of the general population and is highest with high-dose (≥1500 mg or greater total daily) valproate. Carefully considered changes in drug choice and dose may mitigate these risks. Therapeutic drug monitoring plays an important role in pregnancy care, and under expert supervision, women with epilepsy in pregnancy have similar seizure risks as women with epilepsy who are not pregnant. As women with epilepsy age, bone health and menopause may further be impacted by seizures and antiseizure medications. SUMMARY The care of women with epilepsy is a multifaceted discipline that recognizes the life-long impact of sex and gender influences on epilepsy care.

Abstract
BACKGROUND Epilepsy is one of the most common neurologic unit diseases that have different prevalence in different parts of the world. Antiepileptic drugs (AEDs) are associated with major fertility risks for women of childbearing age. Due to the fact that studies on family planning methods in married women with epilepsy (WWE) have not been conducted in Iran, the aim of this study was to evaluate the family planning methods in married WWE in Birjand, Iran. METHODS An analytical-descriptive study was performed on 126 married WWE hospitalized in the neurology ward or referred to Vali-e-Asr specialized and sub-specialized clinic in Birjand. Demographic information of patients as well as data on the type of used AED, and various methods of family planning were collected in a questionnaire. Data analysis was performed using Chi-square and Fisher tests. All of the above analyses were considered at a significance level of less than 5% by SPSS v.19 software. RESULTS The mean age of the patients was 33.41 ± 9.15 years. The mean age of experiencing the first seizure and the onset of menstruation were 24.82 and 13.79 years, respectively. Fifty (35.5%), 38 (27%), 15 (10.6%), 14 (9.9%), and 14 (9.9%) patients used sodium valproate, carbamazepine, phenytoin, levetiracetam, and lamotrigine, respectively. The results showed that 72 sexually active patients (70.6%) used family planning methods, of which 43 patients (59.7%) used withdrawal method, 20 patients (27.8%) used condoms, and 6 patients (8.3%) used oral contraceptive pills (OCP). Eight patients (9.6%) had a history of unintended pregnancy and 3 patients (3.6%) had a history of abortion. CONCLUSION It is recommended to apply effective family planning methods in married WWE to prevent unintended pregnancies and the subsequent adverse effects in the fetus, considering the fact that a significant percentage of WWE did not use effective family planning methods and 8 cases of unintended pregnancies were reported. Because of high consumption of valproate in women of childbearing age in our study and concerning issue about its fetal malformation, it is recommended to reduce the administration of valproate in this population. Moreover, regarding the low consumption of folic acid, especially for women of childbearing age and pregnant WWE who are taking AED, the necessary recommendations should be made by our physicians.

Abstract
Anti-seizure medications (ASMs) fail to prevent seizure recurrence in more than 30% of patients with epilepsy. The treatment is more difficult in premenopausal women with epilepsy (WWE) because changes in plasma estrogen and progesterone concentrations during the menstrual cycle often affect seizure frequency and intensity. Interactions between enzyme-inducin ASMs and hormonal contraceptives can lead to both a loss of seizure control and failure of contraception. Significant changes in the function of the liver and kidneys during pregnancy can accelerate metabolism and elimination of ASMs, causing breakthrough seizures. In addition, the teratogenic, cognitive, and psychological effects of ASMs on potential offspring have to be considered when choosing the best ASM regimen. Therefore, aspecialized approach is necessary for the treatment of premenopausal WWE.

Abstract
Background: In the United States of America (USA), nearly 10 million women use oral contraceptives (OCs). Concomitant administration of certain medications can result in contraceptive failure, and consequently unintended pregnancies due to drug–drug interactions (DDIs). The objective of this analysis was to estimate the economic impact of unintended pregnancies due to DDIs among women of reproductive age using an OC alone or in combination with an enzyme inducer co-medication in the USA from a payer perspective. Methods: A Markov model using a cohort of 1,000 reproductive-age women was developed to estimate costs due to contraceptive failure for OC alone versus OC with concomitant enzyme inducer drugs. All women were assumed to begin an initial state, continuing until experiencing an unintended pregnancy. Unintended pregnancies could result in birth, induced abortion, spontaneous abortion, or ectopic pregnancy. The cohort was analyzed over a time horizon of 1 year with a cycle length of 1 month. Estimates of costs and probabilities of unintended pregnancy outcomes were obtained from the literature. Probabilities from the Markov cohort trace was used to estimate number of pregnancy outcomes. Results: On average, enzyme inducers resulted in 20 additional unintended pregnancies with additional unadjusted and adjusted costs median (range) of USD136,304 (USD57,436–USD320,093) and USD65,146 (USD28,491–USD162,635), respectively. The major component of the direct cost is attributed to the cost of births. Considering the full range of events, DDIs with enzyme inducers could result in 16–25 additional unintended pregnancies and total unadjusted and adjusted costs ranging between USD46,041 to USD399,121 and USD22,839 to USD202,788 respectively. Conclusion: The direct costs associated with unintended pregnancies due to DDIs may be substantial and are potentially avoidable. Greater awareness of DDI risk with oral contraceptives among payers, physicians, pharmacists and patients may reduce unintended pregnancies in at-risk populations.

Abstract
Heavy, and often irregular, menstrual bleeding (HMB) is a common gynecologic complaint among adolescents. During the first few post-menarcheal years, anovulatory cycles related to immaturity of the hypothalamic-pituitary-ovarian axis are the most common etiology for abnormal uterine bleeding and should be considered as a part of normal pubertal development rather than a disease. If an already regular menstrual cycle becomes irregular, secondary causes of anovulation should be ruled out. Inherited and acquired bleeding disorders, such as von Willebrand disease, and quantitative and qualitative abnormalities of platelets are relatively common findings in adolescents with HMB from menarche. History of excessive bleeding or a diagnosed bleeding disorder in the family supports this etiology, warranting specialized laboratory testing. First-line treatment of HMB among adolescents is medical management with hormonal therapy or nonhormonal options. Levonorgestrel-releasing intrauterine device is an effective tool also for all adolescents with menstrual needs.

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
Anti-epileptic drugs (AEDs) are an important group of drugs of several generations, ranging from the oldest phenobarbital (1912) to the most recent cenobamate (2019). Cannabidiol (CBD) is increasingly used to treat epilepsy. The outbreak of the SARS-CoV-2 pandemic in 2019 created new challenges in the effective treatment of epilepsy in COVID-19 patients. The purpose of this review is to present data from the last few years on drug–drug interactions among of AEDs, as well as AEDs with other drugs, nutrients and food. Literature data was collected mainly in PubMed, as well as google base. The most important pharmacokinetic parameters of the chosen 29 AEDs, mechanism of action and clinical application, as well as their biotransformation, are presented. We pay a special attention to the new potential interactions of the applied first-generation AEDs (carbamazepine, oxcarbazepine, phenytoin, phenobarbital and primidone), on decreased concentration of some medications (atazanavir and remdesivir), or their compositions (darunavir/cobicistat and lopinavir/ritonavir) used in the treatment of COVID-19 patients. CBD interactions with AEDs are clearly defined. In addition, nutrients, as well as diet, cause changes in pharmacokinetics of some AEDs. The understanding of the pharmacokinetic interactions of the AEDs seems to be important in effective management of epilepsy.

Abstract
Carbamazepine (CMZ) increases estrogen metabolism by inducing cytochrome P450 (CYP3A4). We investigated whether CMZ is protective against endometrial hyperplasia (EH). We used 32 female Wistar albino rats divided into four equal groups: the control group received drinking water, the estradiol valerate (EV) group was given EV, the CMZ group was given CMZ, and the EV + CMZ group was given both EV and CMZ. After 30 days the uteri of the rats were removed and serum estrogen and progesterone levels were measured, and endometrial tissue characteristics were evaluated. CYP3A4 expression was assessed using immunohistochemistry. Serum estrogen levels were lowest in the EV group and highest in the CMZ group. Serum progesterone levels were similar among all groups. Glandular density, a proxy measure of EH, was highest in the EV group and lowest in the EV + CMZ group. EH was detected in six of eight rats (75%) in the EV group and two of eight rats (25%) in the EV + CMZ group. Immunohistochemical staining revealed no significant difference in CYP3A4 expression among the four groups. CMZ reduced the negative effect of high dose estrogen that is not balanced by progesterone on the endometrium in rats. The effect likely is probably due to the CYP3A4 enzyme activator effect. CMZ may be protective against EH in high risk women, although confirmation is required.

Abstract
Many clinicians lack experience in managing trigeminal autonomic cephalalgias (TACs) in pregnancy and lactation. In addition to cluster headache, TACs include hemicrania continua, paroxysmal hemicrania, and short-lasting unilateral neuralgiform headache with conjunctival injection and tearing/autonomic symptoms (SUNCT/SUNA). Treating these rare, severe headache conditions often requires off-label drugs that have uncertain teratogenic potential. In the last few years, several new treatment options and safety documentation have emerged, but clinical guidelines are lacking. This narrative review aimed to provide an updated clinical guide and good clinical practice recommendations for the management of these debilitating headache disorders in pregnancy and lactation.

Abstract
Epilepsy is one of the most common chronic disorders affecting women of childbearing age. Unfortunately, many women with epilepsy (WWE) still report not receiving key information about pregnancy. They obviously need information about epilepsy and pregnancy prior to conception with a particular emphasis on effective birth control (i.e. contraception), necessity to plan pregnancy, antiepileptic drugs optimization, and folate supplementation. The risks associated with use of antiepileptic drugs during pregnancy have to be balanced against fetal and maternal risks associated with uncontrolled seizures. This report reviews evidence-based counseling and management strategies concerning maternal and fetal risks associated with seizures, teratogenic risks associated with antiepileptic drug exposure with a special emphasis on developmental and behavioural outcomes of children exposed to intra utero antiepileptic drugs.

Abstract
PURPOSE OF REVIEW Nearly two dozen antiseizure medications (ASMs) with different mechanisms of action have been introduced over the past three decades with the aim of providing better efficacy or safety profile than the previous drugs. Several new ASMs with improvement on a classic drug family or have novel mechanisms of action have been recently approved for epilepsy. The present review explored recent studies or guidelines on new agents and discussed the potential impact of these novel treatments on epilepsy management and future directions of research. RECENT FINDINGS Long-term cohort studies showed that, collectively, the second-generation did not improve the overall prognosis of epilepsy. Individual monotherapy studies showed similar efficacy of second-generation (levetiracetam and zonisamide) and third-generation (eslicarbazepine acetate and lacosamide) ASMs compared to controlled-release carbamazepine for the treatment of focal epilepsy. However, there appears to be no evidence to support any second-generation or third-generation ASMs to be as efficacious as valproate monotherapy for generalized and unclassified epilepsies. Cannabidiol adjunctive treatments were found to be efficacious for Dravet syndrome and Lennox-Gastaut syndrome. Although most newer generation ASMs are less prone to drug-drug interactions, stiripentol and cannabidiol can elevate the plasma concentration of N-desmethylclobazam, the active metabolite of clobazam. Generally speaking, the second-generation ASMs have lower teratogenic risk than the older drugs but there is scant study on neurodevelopmental effect of third-generation ASMs. SUMMARY Although the newer generation ASMs may not have improved the overall seizure control they have advantages in terms of drug-drug interactions and teratogenicity, and thus offer valuable individualized options in the treatment of epilepsy.

Inconsistent reporting of drug-drug interactions for hormonal contraception and antiepileptic drugs - Implications for reproductive health for women with epilepsy. Epilepsy Behav 2021; 114:107626.

Abstract
Drug compendia are the source of safety prescribing information. We assessed the reporting concordance of drug-drug interactions between hormonal contraception and antiepileptic drugs (AEDs) among eight leading international drug compendia. Antiepileptic drugs reported to interact with ≥1 form of hormonal contraception were reviewed. Scaled concordance was quantified using linearly weighted percent agreement (wPA). Differences in interaction severity rankings between hormonal contraception forms were evaluated using the Wilcoxon signed-rank test. There was high agreement among compendia for interactions of combined hormonal contraception interactions with AEDs (wPA = 0.82-0.84), especially potent enzyme-inducing AEDs (wPA = 0.89). However, concordance was reduced for AED interactions with progestin-only contraception (wPA = 0.69-0.81). Extreme interaction reporting discrepancies were found for less potent enzyme-inducing AEDs. The greatest variability in interaction reporting was observed for injectable and intrauterine contraception (wPA = 0.69 and 0.70, respectively), which are the only hormonal contraception options currently classified as not interacting with enzyme-inducing AEDs. Drug-drug interaction reporting variability can have major clinical implications and highlights critical knowledge gaps in the care of women with epilepsy of childbearing age. Further research on AED-contraceptive interactions is needed to standardize compendia reporting and enhance evidence-based clinical guidelines for women with epilepsy.

Abstract
Seizure disorders frequently are diagnosed and managed during adolescence; therefore, obstetrician-gynecologists who care for adolescents should be familiar with epilepsy and other seizure disorders, as well as antiepileptic drugs. Patients diagnosed with seizure disorders during childhood may have increased seizure activity with puberty and menarche due to the neuroactive properties of endogenous steroid hormones. Compared with patients without epilepsy, patients with epilepsy are more likely to experience anovulatory cycles, irregular menstrual bleeding, and amenorrhea. Although hormonal suppression should not be initiated before puberty or menarche, prepubertal counseling may be appropriate, and obstetrician-gynecologists may work with young patients and their families to develop a plan to initiate with menarche. Additionally, obstetrician-gynecologists should be aware of any medication changes, including antiepileptics, for adolescent patients with seizure disorders. Research on hormonal therapy for the treatment of epilepsy is scant; however, the anticonvulsant properties of various progestins have been explored as potential treatment. There is no conclusive evidence that combination hormonal contraception increases epileptic seizures, and epilepsy itself poses no increased risk of an adverse outcome for those using combined oral contraceptive pills, the contraceptive patch, or a contraceptive ring. Because many antiepileptic drugs are teratogenic, discussing sexual health with and providing effective contraceptive choices to this population is critical. Obstetrician-gynecologists should work with patients with seizure disorders to develop a plan when pregnancy occurs.

Abstract
It is known that co‐administration of CYP3A inducers may decrease the effectiveness of oral contraceptives containing progestins as mono‐preparations or combined with ethinylestradiol. In a randomized clinical drug‐drug interaction study, we investigated the effects of CYP3A induction on the pharmacokinetics of commonly used progestins and ethinylestradiol. Rifampicin was used to induce CYP3A. The progestins chosen as victim drugs were levonorgestrel, norethindrone, desogestrel, and dienogest as mono‐products, and drospirenone combined with ethinylestradiol. Postmenopausal women (n = 12–14 per treatment group) received, in fixed sequence, a single dose of the victim drug plus midazolam without rifampicin, with rifampicin 10 mg/day (weak induction), and with rifampicin 600 mg/day (strong induction). The effects on progestin exposure were compared with the effects on midazolam exposure (as a benchmark). Unbound concentrations were evaluated for drugs binding to sex hormone binding globulin. Weak CYP3A induction, as confirmed by a mean decrease in midazolam exposure by 46%, resulted in minor changes in progestin exposure (mean decreases: 15–37%). Strong CYP3A induction, in contrast, resulted in mean decreases by 57–90% (mean decrease in midazolam exposure: 86%). Namely, the magnitude of the observed induction effects varied from weak to strong. Our data might provide an impetus to revisit the currently applied clinical recommendations for oral contraceptives, especially for levonorgestrel and norethindrone‐containing products, and they might give an indication as to which progestin could be used, if requested, by women taking weak CYP3A inducers—although it is acknowledged that the exact exposure‐response relationship for contraceptive efficacy is currently unclear for most progestins.

Abstract
BACKGROUND Cobicistat (COBI), a CYP3A inhibitor, is a pharmacokinetic enhancer that increases exposures of the HIV protease inhibitors (PIs) atazanavir (ATV) and darunavir (DRV). The potential drug interaction between COBI-boosted PIs and hormonal contraceptives, which are substrates of intestinal efflux transporters and extensively metabolized by CYP enzymes, glucuronidation and sulfation, was evaluated. METHODS This was a Phase I, open-label, two cohort (n=18/cohort), fixed-sequence study in healthy females that evaluated the drug-drug interaction (DDI) between multiple-dose ATV+COBI or DRV+COBI and single-dose drospirenone/ethinyl estradiol (EE). DDIs were evaluated using 90% confidence intervals of the geometric least-squares mean ratios of the test (drospirenone/EE+boosted PI) versus reference (drospirenone/EE) using lack of DDI boundaries of 70-143%. Safety was assessed throughout the study. RESULTS 29/36 participants completed the study. Relative to drospirenone/EE alone, drospirenone area under the plasma concentration versus time curve extrapolated to infinity (AUCinf) was 1.6-fold and 2.3-fold higher, and maximum observed plasma concentration (Cmax) was unaltered, upon coadministration with DRV+COBI and ATV+COBI, respectively. EE AUCinf decreased 30% with drospirenone/EE + DRV+COBI and was unchanged with ATV+COBI + drospirenone/EE, relative to drospirenone/EE alone. Study treatments were generally well tolerated. The majority of adverse events were mild and consistent with known safety profiles of the compounds. CONCLUSIONS Consistent with COBI-mediated CYP3A inhibition, drospirenone exposure increased following coadministration with COBI-containing regimens, with a greater increase with ATV+COBI. Thus, clinical monitoring for drospirenone-associated hyperkalaemia is recommended with DRV+COBI and ATV+COBI should not be used with drospirenone. Lower EE exposure with DRV+COBI may be attributed to inductive effects of DRV on CYP enzymes and/or intestinal efflux transporters (that is, P-gp) involved in EE disposition.

Abstract
PURPOSE OF REVIEW This article provides the latest information to guide practitioners in counseling and treating women with epilepsy. RECENT FINDINGS There is an increasing body of literature on the multidirectional effects of sex hormones on seizure frequency and severity and of seizures altering areas of the brain involved in neuroendocrine function. Ongoing pregnancy outcome data from pregnancy registries and meta-analysis of observational studies have provided key information on the safety of using antiseizure medications during pregnancy and the risk to the fetus. SUMMARY In treating and counseling women with epilepsy from puberty to menopause, it is important to understand the complex interactions of sex hormones, seizures, and antiseizure medications on reproductive health and pregnancy outcomes.

Abstract
Menstrual suppression (the use of hormonal contraceptive methods to eliminate or significantly decrease the frequency of menstrual cycles) is frequently used in the adolescent population for the management of menstrual symptoms such as heavy or painful periods, premenstrual syndrome, menstrual migraines, or even for patient preference. However, in cases of menstrual suppression in special populations additional risks and benefits need to be considered. The purpose of this article is to review the options and medical considerations for menstrual suppression in patients undergoing chemotherapy who might be at risk of abnormal uterine bleeding, those with intellectual or physical disability, and transgender and gender nonbinary individuals.

Abstract
Abstract
Drug-induced liver injury (DILI) is a major cause for acute liver failure and regulatory actions on novel drugs. Individual patient characteristics are the main determinant of idiosyncratic DILI, making idiosyncratic DILI (iDILI) one of the most challenging diagnoses in hepatology. Individual drug-drug interactions might play a role in iDILI. However, the current approaches to iDILI diagnosis are focused on single drugs as causative agents. For the present analysis, 48 patients with acute liver injury who took 2 drugs and who were diagnosed as iDILI were investigated. A novel in vitro test was employed using monocyte-derived hepatocyte-like cells (MH cells) generated from these patients. iDILI diagnosis and causality were evaluated using clinical causality assessment supported by Roussel-Uclaf Causality Assessment Method. In 13 of these 48 patients (27%), combinations of drugs increased toxicity in the MH test when compared with the single drugs. Interestingly, whereas in 24 cases (50%) drug-drug combinations did not enhance toxicity, in 11 cases (23%) only the combinations caused toxicity. The incidence of severe cases fulfilling Hy’s law was higher in patients with positive interactions (57% vs 43%; p = .04), with acute liver failure occurring in 40% versus 8% (p = .01). The most common drug combinations causing increased toxicity were amoxicillin/clavulanate (8 of 9 cases) and diclofenac in combination with steroid hormones (4 of 9 cases). Drug-drug interactions may influence the incidence and/or the severity of idiosyncratic DILI. MH cell testing can identify relevant drug-drug interactions. The data generated by this approach may improve patient safety.

Abstract
Upadacitinib is a novel selective oral Janus kinase 1 (JAK) inhibitor being developed for treatment of several inflammatory diseases. Oral contraceptives are anticipated to be a common concomitant medication in the target patient populations. This study was designed to evaluate the effect of multiple doses of upadacitinib on the pharmacokinetics of ethinylestradiol and levonorgestrel in healthy female subjects. This phase I, single‐center, open‐label, 2‐period crossover study evaluated the effect of multiple doses of 30 mg once daily extended‐release upadacitinib on the pharmacokinetics of a single oral dose of ethinylestradiol/levonorgestrel (0.03/0.15 mg; administered alone in period 1 and on day 12 of a 14‐day regimen of upadacitinib in period 2) in 22 healthy female subjects. The ratios (90% confidence intervals) for maximum plasma concentration and area under the plasma drug concentration–time curve from time zero to infinity following administration of ethinylestradiol/levonorgestrel with upadacitinib compared with administration of ethinylestradiol/ levonorgestrel alone were 0.96 (0.89–1.02) and 1.1 (1.04–1.19), respectively, for ethinylestradiol, and 0.96 (0.87–1.06) and 0.96 (0.85–1.07), respectively, for levonorgestrel. The harmonic mean terminal half‐life for ethinylestradiol (7.7 vs 7.0 hours) and levonorgestrel (37.1 vs 33.1 hours) was similar in the presence and absence of upadacitinib. Ethinylestradiol and levonorgestrel were bioequivalent in the presence and absence of upadacitinib. Therefore, upadacitinib can be administered concomitantly with oral contraceptives containing ethinylestradiol or levonorgestrel.

Abstract
Hormonal contraceptive agents (HCAs) are widely used throughout the world, and women taking HCAs are likely to take other medications. However, little is known about the clinical effect of most drug‐drug interactions (DDIs) associated with HCAs. A team of interdisciplinary outcomes and pharmacometric researchers from academia and industry jointly engage in a research project to (i) quantitatively elucidate DDI impacts on unintended pregnancies and breakthrough bleeding, and (ii) establish a DDI‐prediction framework to inform optimal use of HCAs.

Abstract
OBJECTIVE Multipurpose prevention technologies (MPTs) are an innovative class of products that deliver varied combinations of human immunodeficiency virus (HIV) prevention, other sexually transmitted infection (STI) prevention, and contraception. Combining separate strategies for different indications into singular prevention products can reduce the stigma around HIV and STI prevention, improve acceptability of and adherence to more convenient products, and be more cost-effective by addressing overlapping risks. METHODS This article outlines a strategic action framework developed as an outcome of a series of expert meetings held between 2014 and 2016. The meetings focused on identifying opportunities and challenges for MPTs that combine hormonal contraception (HC) with antiretroviral drugs into single products. The framework aims to present an actionable strategy, by addressing key research gaps and outlining the key areas for progress, to guide current and future HC MPT development. RESULTS We identified eight primary action areas for the development of impactful HC MPTs, and includes aspects from epidemiology, pharmacology, clinical trial design, regulatory requirements, manufacturing and commercialisation, behavioural science, and investment needs for research and development. CONCLUSION Overall, the challenges involved with reconciling the critical social-behavioural context that will drive MPT product use and uptake with the complexities of research and development and regulatory approval are of paramount importance. To realise the potential of MPTs given their complexity and finite resources, researchers in the MPT field must be strategic about the way forward; increased support among policy-makers, advocates, funders and the pharmaceutical industry is critical.

Abstract
ObjectiveTo compare the proportions of unintended pregnancies, prenatal vitamin or folic acid (PNVF) use, adequate prenatal care visits, and breastfeeding among women with epilepsy (WWE) to women without epilepsy (WWoE).MethodsThe Pregnancy Risk Assessment Monitoring System (PRAMS) is an annual survey of randomly sampled postpartum women administered by the Centers for Disease Control and Prevention. We used PRAMS data from 13 states from 2009 to 2014 to compare the primary outcomes in WWE and WWoE, as well as our secondary outcomes of contraception practices, newborn outcomes, and time to recognition of pregnancy. We adjusted for maternal age, race, ethnicity, and socioeconomic status (SES), and we calculated odds ratios for these outcomes using logistic regression.ResultsThis analysis included 73,619 women, of whom 541 (0.7%) reported epilepsy, representing 3,442,128 WWoE and 26,635 WWE through weighted sampling. In WWE, 55% of pregnancies were unintended compared to 48% in WWoE. After adjustment for covariates, epilepsy was not associated with unintended pregnancy or with inadequate prenatal care. WWE were less likely to report breastfeeding but more likely to report daily PNVF use. Newborns of WWE had higher rates of prematurity.ConclusionsAlthough planning for pregnancy is of utmost importance for WWE, more than half the pregnancies in WWE were unintended. Maternal age and SES differences likely contribute to the higher rates in WWE compared to WWoE. The proportion of women reporting breastfeeding is lower in WWE despite studies indicating the safety of breastfeeding in WWE.

Sexual and Reproductive Health in Patients with Schizophrenia and Bipolar Disorder. ACTA ACUST UNITED AC 2018; 49:15-22. [PMID: 32081203 DOI: 10.1016/j.rcp.2018.04.007] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2017] [Revised: 03/05/2018] [Accepted: 04/13/2018] [Indexed: 11/18/2022]
Abstract
INTRODUCTION People with schizophrenia and bipolar disorder (BD) have a high risk of unwanted pregnancies and abortions, due to their condition of vulnerability or hypersexuality (common in BD). This is associated with difficulty in planning their actions and lack of sex education and counselling by medical personnel, and can lead to adverse obstetric outcomes and inability to care adequately for their children. OBJECTIVE To describe the characteristics in terms of sexual and reproductive health, and the use of contraception and counselling in psychiatric consultations, in a sample of patients with BD and schizophrenia in Medellin, Colombia. METHODS Observational cross-sectional study. We included the 160 participants from the clinical trial, "The effects of a multimodal intervention programme in patients with bipolar disorder and schizophrenia", who were recruited from the mood and psychosis disorders group clinic at Hospital Universitario de San Vicente Fundación in Medellin. They were contacted by phone by a third-year psychiatry resident, who applied a survey about the characteristics of their sex life, contraception and reproduction. RESULTS Almost all of the patients with schizophrenia were single, had no undergraduate studies and were unemployed. No significant differences were found regarding the age of starting sexual relations when comparing by diagnosis and gender. Almost all patients with schizophrenia and almost half of the patients with BD reported not having an active sexual life. Almost all of those who admitted to having an active sexual life claimed to always use contraception; in the BD group, only 48.8% of single women admitted to using contraception and a little over half of men stated that they used a condom when having sex. A quarter of the pregnancies were unplanned. Although the majority of the patients stated that they had never received information about family planning in the consultations with their psychiatrist, 57.4% of the patients with BD and 78.8% of those who had schizophrenia, considered themselves to be well informed on the subject. CONCLUSIONS Patients with mental illness have cognitive and behavioural alterations that affect their sexual and reproductive lives. Psychiatrists should therefore address this issue, to ensure education in areas such as contraception, family planning and sexually transmitted diseases and help safeguard the safety and quality of life of their patients.

Abstract
INTRODUCTION Eslicarbazepine acetate was first approved in the European Union in 2009 as adjunctive therapy in adults with partial-onset seizures with or without secondary generalization. OBJECTIVE The objective of this study was to review the safety profile of eslicarbazepine acetate analyzing the data from several clinical studies to 6 years of post-marketing surveillance. METHODS We used a post-hoc pooled safety analysis of four phase III, double-blind, randomized, placebo-controlled studies (BIA-2093-301, -302, -303, -304) of eslicarbazepine acetate as add-on therapy in adults. Safety data of eslicarbazepine acetate in special populations of patients aged ≥65 years with partial-onset seizures (BIA-2093-401) and subjects with moderate hepatic impairment (BIA-2093-111) and renal impairment (BIA-2093-112) are also considered. The incidences of treatment-emergent adverse events, treatment-emergent adverse events leading to discontinuation, and serious adverse events were analyzed. The global safety database of eslicarbazepine acetate was analyzed for all cases from post-marketing surveillance from 1 October, 2009 to 21 October, 2015. RESULTS From a pooled analysis of four phase III studies, it was concluded that the incidence of treatment-emergent adverse events, treatment-emergent adverse events leading to discontinuation, and adverse drug reactions were dose dependent. Dizziness, somnolence, headache, and nausea were the most common treatment-emergent adverse events (≥10% of patients) and the majority were of mild-to-moderate intensity. No dose-dependent trend was observed for serious adverse events and individual serious adverse events were reported in less than 1% of patients. Hyponatremia was classified as a possibly related treatment-emergent adverse event in phase III studies (1.2%); however, after 6 years of post-marketing surveillance it represents the most frequently (10.2%) reported adverse drug reaction, with more than half of these cases occurring with eslicarbazepine acetate at daily doses of 1200 mg. Other adverse drug reactions reported in post-marketing surveillance are seizure (5.8%), dizziness (4.1%), rash (2.6%), and fatigue (2.1%). The safety profile of eslicarbazepine acetate in renal and hepatic impairment subjects (phase I studies) and in elderly patients (phase III study) did not raise any specific concern. CONCLUSION After 6 years of post-marketing surveillance, eslicarbazepine acetate maintains a similar safety profile to that observed in pivotal clinical studies.

Abstract
One method for causal analysis in the social sciences is structural modeling. Structural models, as used in this article, model the (causal) mechanism for a social phenomenon by recursively decomposing the multivariate distribution of the variables of interest. Often, however, one does not achieve a complete decomposition in terms of single variables but in terms of “blocks” of variables only. Papers giving an overview of this issue are nevertheless rare. The purpose of this article is to categorize distinct types of block-recursivity and to examine, in a multidisciplinary perspective, the implications of block-recursivity for causal attribution. A probabilistic approach to causality is first developed in the framework of a structural model. The article then examines block-recursivity due to the presence of contingent conditions, of interaction, and of conjunctive causes. It also discusses causal attribution when information on the ordering of the variables is incomplete. The article concludes by emphasizing, in particular, the importance of properly specifying the population of reference.

Abstract
OBJECTIVE The aim of this study was to develop and achieve consensus on a core list of important knowledge items that community pharmacists should know on women's issues in epilepsy. METHODS This was a consensual study using a modified Delphi technique. Knowledge items were collected from the literature and from nine key contacts who were interviewed on their views on what information community pharmacists should have on women's issues in epilepsy. More knowledge items were suggested by five researchers with interest in women's issues who were contacted to rate and comment on the knowledge items collected. Two iterative Delphi rounds were conducted among a panel of pharmacists (n=30) to achieve consensus on the knowledge items to be included in the core list. Ten panelists ranked the knowledge items by their importance using the Analytical Hierarchy Process (AHP). RESULTS Consensus was achieved to include 68 knowledge under 13 categories in the final core list. Items ranked by their importance were related to the following: teratogenicity (10.3%), effect of pregnancy on epilepsy (7.4%), preconception counseling (10.3%), bone health (5.9%), catamenial epilepsy (7.4%), menopause and hormonal replacement therapy (2.9%), contraception (14.7%), menstrual disorders and infertility (8.8%), eclampsia (2.9%), breastfeeding (4.4%), folic acid and vitamin K (5.9%), counseling on general issues (14.7%), and sexuality (4.4%). CONCLUSION Using consensual knowledge lists might promote congruence in educating and/or training community pharmacists on women's issues in epilepsy. Future studies are needed to investigate if such lists can improve health services provided to women with epilepsy (WWE).

Abstract
OBJECTIVE Approximately 25 million individuals older than age 15 identify as transgender, representing about 0.3-0.9% of the world's population. The aim of this paper is to identify and describe important medical and social considerations facing transgender persons with epilepsy. METHODS We performed literature searches on the following terms: transgender AND epilepsy, transgender AND neurology, gender dysphoria AND epilepsy, gender dysphoria AND neurology. We also performed literature searches for common feminizing or masculinizing treatment regimens, and searched for interactions of those treatment regimens with antiepileptic drugs (AEDs) and with seizures. RESULTS There are multiple bidirectional interactions between AEDs and the commonly used treatments for aligning external sex characteristics with identified gender. The scope of the transgender population with epilepsy remains to be elucidated. SIGNIFICANCE Transgender patients with epilepsy face significant social and medical challenges. Interactions between medical gender-affirming treatments and AEDs are common, and management must depend on knowledge of these interactions to provide appropriate treatment.

Abstract
Adolescence is a period of rapid change, both physical and psychosocial for any young person. It can be challenging when they have ongoing health problems and when their care needs to be transitioned to the adult health care system. Transition should be a planned process of addressing the medical and associated comorbid conditions from pediatric to adult care in a coordinated manner. In most cases, the young person and their family are well known to the pediatrics services and have built a relationship based on trust and often friendship over many years. Understandably, there is significant apprehension about moving from this familiar setting to the unknown adult services. Apart from having a sound knowledge of specific childhood epileptic conditions and associated comorbid disorders, it is important that both the pediatric and adult epilepsy teams are motivated to provide a successful and safe transition for these patients. It is essential that transition is seen as a continual process and not as a single event, and good preparation is the key to its success. It is also important that general practitioners are closely engaged to ensure successful transition. An overview of how to effectively address transition in epilepsy, different models of transition, transition of relevant epilepsies, and their management is discussed.

Abstract
Approximately 50% of all pregnancies in women with epilepsy (WWE) occur unplanned. This is worrying, given the increased occurrence of obstetrical complications in WWE, including the risk of seizures and their possible consequences for both the mother and the unborn child. Hormonal contraception is usually regarded as highly effective, but it is subject to numerous bidirectional drug interactions with several antiepileptic drugs. These interactions may lead to loss of seizure control or contraceptive failure. Further concerns are loss of bone mineral density and increased seizure activity due to hormonal effects. Many physicians lack sufficient knowledge regarding these issues, and most WWE have never received adequate counseling. Moreover, several studies show that a large proportion of WWE do not take their medicines regularly. This article reviews all of these issues and offers practical recommendations for the management of contraception in WWE.

Abstract
OBJECTIVES In comparison with controls, youth with epilepsy (YWE) have greater psychosocial problems. However, information about their sexual behavior is sparse. We have performed a large, population-based questionnaire study to examine differences in sexual behavior between YWE and controls. METHODS A randomly chosen cohort of youth (13-19 years) from Akershus county, Norway (n=19,995) was asked to complete a questionnaire anonymously with questions on epilepsy and sexual activity. RESULTS The response rate was 85%. Two hundred forty-seven participants reported having or having had epilepsy, i.e., a lifetime epilepsy prevalence of 1.2%. Compared with controls, a higher proportion of YWE reported having had sexual intercourse (43.6% vs. 35.3%, p=0.009). The mean age at sexual debut was significantly lower in YWE than in controls (14.0 years vs. 15.0 years, p<0.001), and this was particularly marked among boys. A higher proportion of YWE reported not having used contraceptives at their last sexual intercourse compared with controls (31.6% vs. 22.3%, p=0.03). Ten percent of YWE, compared with 2% of the controls, reported that they had been forced into their first sexual intercourse. CONCLUSION In YWE, some aspects of sexual behavior differ from those of their peers, with earlier sexual debut and less frequent use of contraceptives. More attention should be directed toward this subject, aiming at avoiding unwanted pregnancies and potential emotional traumas in this already vulnerable patient group.
