Adverse childhood experiences (ACEs) are commonly observed in the general population and often have lasting neurological and physiological effects. Previous studies have found links between exposure to ACEs, headaches, and functional difficulties in adults. However, little is known about the mechanisms through which exposure to ACEs is associated with headaches among children.

To examine the association between exposure to ACEs and headaches in children, and whether functional difficulties mediate this association.

Data for this cross-sectional secondary analysis study came from the 2017-2018 National Survey of Children's Health. The sample analyzed in this study was 40,953 children who were between ages 3 and 17years. We adjusted for the complexity of the sampling design and used structural equation modeling to examine the mediating effect of functional difficulties in the association between exposure to ACEs and headaches.

Based on parent reports, we found that 4.1% (1697/40,953) of the children reponal difficulties partially mediate this association.
To evaluate the efficacy of fremanezumab in patients with chronic migraine (CM) and moderate to severe depression.

Fremanezumab, a fully humanized monoclonal antibody that selectively targets calcitonin gene-related peptide, has been approved for the preventive treatment of migraine in adults. CM and depression are highly comorbid.

The 12-week, Phase 3 HALO trial randomized patients with CM to fremanezumab quarterly (675mg/placebo/placebo), fremanezumab monthly (675/225/225mg), or placebo. Post hoc analyses evaluated the effects of fremanezumab in patients with moderate to severe depression (baseline 9-item Patient Health Questionnaire sum score ≥10) on monthly number of headache days of at least moderate severity; monthly migraine days; Patient Global Impression of Change (PGIC); 6-item Headache Impact Test (HIT-6) scores; and depression.

For the 219/1121 (19.5%) patients with moderate to severe depression at baseline, fremanezumab was associated with a significant reduction in monthly number of headache days of at least moderate severity for active treatment versus placebo (least-squares mean change±standard error for quarterly dosing -5.3±0.77; for monthly dosing -5.5±0.72; and for placebo -2.2±0.81; both p<0.001). More patients achieved a ≥50% reduction in headache days of at least moderate severity with fremanezumab (quarterly 31/78 [39.7%]; monthly 39/96 [40.6%]) than placebo (9/67 [13.4%]; both p<0.001). Compared with placebo, fremanezumab improved PGIC and HIT-6 scores.

Fremanezumab demonstrated efficacy in the preventive treatment of CM and reduced headache impact in patients with comorbid depression.

They also affect neurological development of the brain, but their role in cerebral OXPHOS before birth remains largely unknown, despite the increase in cerebral energy demand during the neonatal period. Thus, this study examined prepartum development of cerebral OXPHOS in hypothyroid fetal sheep. Using respirometry, Complex I (CI), Complex II (CII), and combined CI&CII OXPHOS capacity were measured in the fetal cerebellum and cortex at 128 and 142 days of gestational age (dGA) after surgical thyroidectomy or sham operation at 105 dGA (term ~145 dGA). Mitochondrial electron transfer system (ETS) complexes, mRNA transcripts related to mitochondrial biogenesis and ATP production, and mitochondrial density were quantified using molecular techniques. Cerebral morphology was assessed by immunohistochemistry and stereology. In the cortex, hypothyroidism reduced CI-linked respiration and CI abundance at 128 dGA and 142 dGA, respectively, and caused upregulation of PGC1α (regulator of mitochondrial biogenesis) and thyroid hormone receptor β at 128 dGA and 142 dGA, respectively. In contrast, in the cerebellum, hypothyroidism reduced CI&II- and CII-linked respiration at 128 dGA, with no significant effect on the ETS complexes. In addition, cerebellar glucocorticoid hormone receptor and adenine nucleotide translocase (ANT1) were downregulated at 128 dGA and 142 dGA, respectively. These alterations in mitochondrial function were accompanied by reduced myelination. The findings demonstrate the importance of thyroid hormones in the prepartum maturation of cerebral mitochondria and have implications for the etiology and treatment of the neurodevelopmental abnormalities associated with human prematurity and congenital hypothyroidism.The search for economical, active and stable electrocatalysts towards the hydrogen evolution reaction (HER) is highly imperative for the progression of water electrolysis technology and related sustainable energy conversion technologies. The delicate optimization of chemical composition and architectural configuration is paramount to design high-efficiency non-precious metal HER electrocatalysts. Herein, we report a one-step scalable template/solvent-free pyrolysis approach for in situ immobilizing uniform CoP nanoparticles onto N and P co-doped carbon porous nanosheets (denoted as CoP@N,P-CNSs hereafter). The simultaneous consideration of architectural design and nanocarbon hybridization renders the formed CoP@N,P-CNSs with plentiful well-dispersed anchored active sites, shortened pathway for mass diffusion, enhanced electric conductivity, and reinforced mechanical stability. A-1210477 As a consequence, the optimized CoP@N,P-CNSs exhibit an overpotential of 115 mV to afford a current density of 10 mA cm-2 , small Tafel slope of 74.2 mV dec-1 , high Faradaic efficiency of nearly 100 %, and superb long-term durability in an alkaline medium. Given the fabrication feasibility, mass production potential and outstanding HER performance, the CoP@N,P-CNSs may hold great promise for large-scale electrochemical water splitting. More importantly, the explored one-step template/solvent-free pyrolysis methodology offers a feasible and versatile route to fabricate carbon nanosheet-based nanocomposites for diverse energy conversation-related applications.
