摘要： Background and Objective Comprehensive headache care involves numerous specialties and components that have not been well documented or standardized. This study aimed to elicit best practices and characterize important elements of care to be provided in multidisciplinary headache centers. Methods Qualitative, semi-structured telephone interviews with a purposive sample of headache neurology specialists from across the US, using open-ended questions. Interviews were recorded, transcribed, and coded. Coded data were further analyzed using immersion/crystallization techniques for final interpretation. Results Mean years providing headache care was 17.7 (SD = 10.6). Twelve of the 13 participants held United Council for Neurologic Subspecialties headache certification. Six described their practice site as providing multidisciplinary headache care. Participants explained most of their patients had seen multiple doctors over many years, and had tried numerous unsuccessful treatments. They noted patients with chronic headache frequently present with comorbidities and become stigmatized. All participants asserted successful care depends on taking time to talk with and listen to patients, gain understanding, and earn trust. All participants believed multidisciplinary care is essential within a comprehensive headache center, along with staffing enough headache specialists, implementing detailed headache intake and follow-up protocols, and providing the newest medications, neuromodulation devices, botulinum toxin injections, monoclonal antibodies, nerve blocks and infusions, and treatment from a health psychologist. Other essential services for a headache center are other behavioral health practitioners providing cognitive behavioral therapy, mindfulness, biofeedback and pain management;and autonomic neurology, neuropsychology, vestibular audiology, sleep medicine, physical therapy, occupational therapy, exercise physiology, speech therapy, nutrition, complementary integrative

摘要： Introduction Neurological manifestation of dengue virus infection is a rare entity. Serotypes commonly associated with neurological manifestation are DENV-2 and DENV-3. We plan to detect the serotypes related to the neurological presentation in dengue infection and its correlation with different neurological complications and outcome. Methods In this case-control study, consecutive dengue cases with different neurological manifestations were enrolled along with age and sex-matched controls (dengue patients without neurological complication). Serotyping using RT-PCR of samples of cases and controls were done. Level of correlation was analyzed with various parameters and outcomes. Results In cases out of 33 samples, 6 sample serotypes were detected, which were composed of DENV-1 (n = 2) and DENV-2 (n = 4). In controls, DENV-1 (n = 5), DENV-2 (n = 6), and DENV-3 (n = 3) were detected. When statistically correlated, no significant association was found in cases and controls with dengue virus serotype. The frequency of serotype 2 was higher in hypokalemic paralysis cases than non-hypokalemic paralysis cases and the difference was significant (p < 0.05). The outcome was good (mRS < 3) in all the cases where serotypes were detected, but on statistical correlation, it was not found significant (p > 0.05). Conclusion DENV-1 and DENV-2 are associated with neurological manifestation of dengue infection, which is different from the existing literature, where DENV-2 and DENV-3 are reported. The detection of DENV serotype will help in predicting and best management of neurological complication. The serotype 2 of dengue virus is more commonly associated with dengue-associated hypokalemic paralysis than other neurological complication (p < 0.05). There is no significant association of serotypes with outcome or mortality.

摘要： The reactive astrocytes manifest molecular, structural, and functional remodeling in injury, infection, or diseases of the CNS, which play a critical role in the pathological mechanism of neurological diseases. A growing need exists for dependable approach to better characterize the activation of astrocyte in vivo. As an advanced molecular imaging technology, positron emission tomography (PET) has the potential for visualizing biological activities at the cellular levels. In the review, we summarized the PET visualization strategies for reactive astrocytes and discussed the applications of astrocyte PET imaging in neurological diseases. Future studies are needed to pay more attention to the development of specific imaging agents for astrocytes and further improve our exploration of reactive astrocytes in various diseases.

摘要： The blood-brain barrier (BBB) protects the central nervous system (CNS) from harmful blood-borne factors. Although BBB dysfunction is a hallmark of several neurological disorders, therapies to restore BBB function are lacking. An attractive strategy is to repurpose developmental BBB regulators, such as Wnt7a, into BBB-protective agents. However, safe therapeutic use of Wnt ligands is complicated by their pleiotropic Frizzled signaling activities. Taking advantage of the Wnt7a/b-specific Gpr124/Reck co-receptor complex, we genetically engineered Wnt7a ligands into BBB-specific Wnt activators. In a "hit-and-run" adeno-associated virus-assisted CNS gene delivery setting, these new Gpr124/Reck-specific agonists protected BBB function, thereby mitigating glioblastoma expansion and ischemic stroke infarction. This work reveals that the signaling specificity of Wnt ligands is adjustable and defines a modality to treat CNS disorders by normalizing the BBB.

摘要： Background Alternating of Childhood (AHC) is an uncommon and complex disorder characterized by age of onset before 18 months with recurrent hemiplegia of one or either sides of the body or quadriplegia. The disorder is mainly caused by mutations in ATP1A3 gene, and to a lesser extent in ATP1A2 gene. In AHC neurological co-morbidities are various and frequently reported including developmental delay, epilepsy, tonic or dystonic spells, nystagmus,autonomic manifestations with intrafamilial variability. Case presentation Clinical and genetic findings of a couple of twins (Family 1: Case 1 and Case 2) and a couple of siblings (Family 2: Case 3 and Case 4) coming from two different Italian families affected by AHC were deeply examined. In twins of Family 1, a pathogenic variant in ATP1A3 gene (c.2318A>G) was detected. In siblings of Family 2, the younger brother showed a novel GRIN2A variant (c.3175 T > A), while the older carried the same GRIN2A variant, and two missense mutations in SCNIB (c.632 > A) and KCNQ2 (1870 G > A) genes. Clinical manifestations of the four affected children were reported along with cases of AHC drawn from the literature. Conclusions Hemiplegic episode is only a sign even if the most remarkable of several and various neurological comorbidities in AHC affected individuals. Molecular analysis of the families here reported showed that clinical features of AHC may be also the result of an unexpected genetic heterogeneity.
