RESUMO
OBJECTIVE: To summarize the unique aspects of managing headache in gender minorities and current research in this area including the potential relationship between gender-affirming hormone therapy (GAHT) and headache. BACKGROUND: The study of headache in gender minorities is intrinsically important. Gender minorities are medically underserved, and their medical care to date has been limited by socioeconomic disadvantages including stigma and an unsupportive clinical environment. Despite the rising population of transgender and gender-diverse adults and youth, headache research has also been limited. Knowledge of hormonal effects on headache in cisgender patients raises the question of possible effects of GAHT on transgender patients. METHODS/RESULTS: The manuscript is a narrative review of current best practices in treating transgender patients, including the use of appropriate terminology and ways to create a supportive environment. It also contains current guidelines on GAHT and reviews drug-drug interactions and secondary headache related to hormone therapy. We also review transgender headache research and related research on hormonal effects on headache in cisgender individuals. CONCLUSION: Creating a supportive environment for transgender and gender-diverse patients and being knowledgeable about GAHT are key to providing quality headache care. This review identifies further research needs for this population including the epidemiology of headache disorders in sexual minorities and the potential effects of GAHT on headache disorders in transgender patients.

OBJECTIVE: To equip clinicians with recommendations specific to concerns related to the novel coronavirus disease 2019 (COVID-19), which impact the physical, emotional, and social health of youth with headache disorders. BACKGROUND: COVID-19 has affected societies on a global scale including children and youth with chronic headache disorders. Many concerns are predicted to arise in the 2020-2021 school year, whether classes are conducted in-person or virtually. METHODS: Clinical impressions were combined with a review of the literature, although limited due to the recent nature of this issue. RESULTS: We describe recommendations to support caregivers and youth as they face changes expected with the return to school in the fall of 2020. CONCLUSION: Although there are significant concerns for caregivers and youth with migraine given the context of changes related to the pandemic, there are many recommendations that can help minimize exacerbations of the physical, emotional, and social health of youth with chronic migraine.

PURPOSE OF REVIEW: Understanding comorbidities in migraine is important because it can help us understand disease pathophysiology while also aiding the development of more effective treatment strategies. Additionally, it can provide greater awareness about appropriate diagnosis, the need for additional disease screening, and the natural history of migraine. Psychiatric comorbidities have been independently studied in both adults and children with migraine because their presentations can be distinct, and the physiology in these two groups can be different. RECENT FINDINGS: While symptoms of anxiety and depression seem to be comorbid with migraine in children, clinically significant disease does not appear to be, though the clarity of these data is limited by overlap between migraine symptomatology and that assessed by many screening tools. Functional neurologic disorders like psychogenic non-epileptic episodes (PNEE) and other functional movement disorders are not common but can be comorbid with migraine in this population and tend to improve with migraine treatment. The number of adverse childhood experiences (ACEs) a child is exposed to seems to be near-linearly associated with risk of migraine, but not with tension-type headache (TTH). The findings from these studies underscore the importance of utilizing appropriate screening methodologies for identifying psychiatric disorders in children with migraine. Additionally, the role of the insula, the hypothalamic-pituitary-adrenal axis, the serotonergic system, and the instability of hyperactivated neural networks may underlie the pathophysiology of both migraine and its psychiatric comorbidities.

PURPOSE OF REVIEW: This review aims to discuss the experience of migraine in transgender and gender-diverse individuals as it relates to other psychiatric comorbidities such as anxiety, depression, PTSD, and others. As this population faces stigma and discrimination, literature posits that gender minority stress can also contribute to the experience of pain in these individuals. RECENT FINDINGS: Though there is little explicit data on these topics, more recent studies have explored the concept of gender minority stress and how stigma and discrimination can affect health outcomes and overall perception of health. These findings, as well as data on psychiatric comorbidities in cisgender individuals with migraine, can be extrapolated to understand how gender minority individuals may experience migraine. Research has demonstrated that stigma and discrimination can affect health outcomes in the transgender and gender-diverse community. A recent study has shown that sexual minority stress associated with stigma, discrimination, and barriers to care can exacerbate migraine. It is known that psychiatric comorbidities such as anxiety, depression, and PTSD can affect migraine frequency and severity in cisgender individuals. Though there are no specific studies in the transgender and gender-diverse patient population, these highly prevalent mental health conditions could potentially contribute to their migraine experience. Hormones, as well, may affect mood in those on gender-affirming hormone therapy, with some studies exploring how this may have both a direct and indirect relationship with migraine. There are clear knowledge gaps that can be addressed by future research in these areas to better understand the migraine experience in transgender and gender-diverse individuals and improve overall care.

BACKGROUND: Alcohol-related brain degeneration is linked to cognitive-motor deficits and impaired signaling through insulin/insulin-like growth factor type 1 (IGF-1)-Akt pathways that regulate cell survival, plasticity, metabolism, and homeostasis. In addition, ethanol inhibits Aspartyl-asparaginyl-ß-hydroxylase (ASPH), a downstream target of insulin/IGF-1-Akt signaling and an activator of Notch networks. Previous studies have suggested that early treatment with insulin sensitizers or dietary soy could reduce or prevent the long-term adverse effects of chronic ethanol feeding. OBJECTIVE: The goal of this study was to assess the effects of substituting soy isolate for casein to prevent or reduce ethanol's adverse effects on brain structure and function. METHODS: Young adolescent male and female Long Evans were used in a 4-way model as follows: Control + Casein; Ethanol + Casein; Control + Soy; Ethanol + Soy; Control = 0% ethanol; Ethanol = 26% ethanol (caloric). Rats were fed isocaloric diets from 4 to 11 weeks of age. During the final experimental week, the Morris Water maze test was used to assess spatial learning (4 consecutive days), after which the brains were harvested to measure the temporal lobe expression of the total phospho-Akt pathway and downstream target proteins using multiplex bead-based enzyme-linked immunosorbent assays (ELISAs) and duplex ELISAs. RESULTS: Ethanol inhibited spatial learning and reduced brain weight, insulin signaling through Akt, and the expression of ASPH when standard casein was provided as the protein source. The substitution of soy isolate for casein largely abrogated the adverse effects of chronic ethanol feeding. In contrast, Notch signaling protein expression was minimally altered by ethanol or soy isolate. CONCLUSIONS: These novel findings suggest that the insulin sensitizer properties of soy isolate may prevent some of the adverse effects that chronic ethanol exposure has on neurobehavioral function and insulin-regulated metabolic pathways in adolescent brains.

BACKGROUND: Fetal alcohol spectrum disorder (FASD) is associated with deficits in cerebellar function that can persist through adolescence. Previous studies demonstrated striking inhibition of insulin and insulin-like growth factor (IGF) signaling in ethanol-exposed cerebella. OBJECTIVES: We sought to determine if FASD-induced impairments in motor function were associated with deficits in insulin/IGF signaling in juvenile cerebella. Given the growing evidence that insulin/IGF pathways cross-talk with Notch and Wnt to promote brain development and maturation; we also examined the integrity of canonical Wnt and Notch signaling networks in the brain following chronic prenatal ethanol exposure. METHODS: Pregnant Long Evans rats were fed isocaloric liquid diets containing 0% or 24% ethanol by caloric content from gestation day 6 through delivery. Pups were subjected to rotarod testing on postnatal days (P) 15-16 and sacrificed on P30. Cerebella were used for molecular and biochemical analysis of insulin/IGF-1, canonical Wnt, and Notch signaling mechanisms. RESULTS: Prenatal ethanol exposures impaired rotarod performance, inhibited signaling through insulin and IGF-1 receptors, IRS-1, and Akt, increased activation of GSK-3ß, and broadly suppressed genes mediating the canonical Wnt and Notch networks. CONCLUSIONS: Abnormalities in cerebellar function following chronic prenatal ethanol exposure are associated with inhibition of insulin/IGF, canonical Wnt, and Notch networks that cross-talk via GSK-3ß. Effective therapeutic measures for FASD may require multi-pronged support of interrelated signaling networks that regulate brain development.
RESUMO
BACKGROUND: Chronic or binge ethanol exposures during development can cause fetal alcohol spectrum disorder (FASD) which consists of an array of neurobehavioral deficits, together with structural, molecular, biochemical, and neurotransmitter abnormalities in the brain. Previous studies showed that perinatal neurodevelopmental defects in FASD are associated with inhibition of brain insulin and insulin-like growth factor (IGF) signaling. However, it is not known whether sustained abnormalities in adolescent brain structure and function are mediated by the same phenomena. AIMS: Using an early postnatal (3rd trimester equivalent) binge ethanol exposure model, we assessed neurobehavioral function, structure, and the integrity of insulin/IGF signaling in young adolescent cerebella. METHODS: Long Evans male rats were treated with 50 µl of saline (vehicle) or 2 mg/kg of ethanol by i.p. injection on postnatal days (P) 2, 4, 6, and 8. On P19-20, rats were subjected to rotarod testing of motor function, and on P30, they were sacrificed to harvest cerebella for histological, molecular, and biochemical studies. RESULTS: Binge ethanol exposures impaired motor function, caused sustained cerebellar hypocellularity, and reduced neuronal and oligodendrocyte gene expression. These effects were associated with significant deficits in insulin and IGF signaling, including impaired receptor binding, reduced Akt, and increased GSK-3ß activation. CONCLUSIONS: FASD-associated neurobehavioral, structural, and functional abnormalities in young adolescent brains may be mediated by sustained inhibition of insulin/IGF-1 signaling needed for cell survival, neuronal plasticity, and myelin maintenance.
