The present open-label multicenter pilot study sought to prospectively evaluate the efficacy and safety of rimegepant in treating migraine attacks. The primary endpoint was pain freedom at two hours post-dose, while the co-primary efficacy endpoints included a reduction in the headache intensity and freedom from the most bothersome symptoms (MBS) associated with migraine at the same time point. To test the potential efficacy of rimegepant, patients were asked to record in a questionnaire all the relevant changes with each migraine attack treated with rimegepant at two hours post-dose vs.

Objective: This post-hoc analysis of data extracted from a prospective study aimed to explore for the first time if the efficacy of fremanezumab in preventing difficult-to-treat migraine, according to ICHD-III, would differ between pre-menopausal and post-menopausal women.

Methods: A total of 171 (aged 18-70 years) fremanezumab-treated female migraine patients for six consecutive months were classified to those at pre-menopausal ( = 82) or post-menopausal ( = 89). Monthly headache days (MHD), disability, and quality of life (QOL) outcomes were assessed at baseline and at week 24 post-fremanezumab within subgroups and were then compared between them.

Background: We primarily aimed to ascertain whether treatment with OnabotulinumtoxinA (BoNTA) might influence the extent of the interictal burden and cutaneous allodynia in patients with chronic migraine (CM).

Methods: Seventy CM patients, who received three consecutive cycles of BoNTA, were studied. The interictal burden was assessed with the Migraine Interictal Burden Scale (MIBS-4), while cutaneous allodynia was examined with the Allodynia Symptom Checklist (ASC-12) together with PI-NRS VAS to obtain hair brushing scores, and then these were compared from baseline (T0) to the last efficacy evaluation follow-up (T1).

Transposable elements (TEs) are prevalent repeats in the human genome, play a significant role in the regulome, and their disruption can contribute to tumorigenesis. However, TE influence on gene expression in cancer remains unclear. Here, we analyze 275 normal colon and 276 colorectal cancer samples from the SYSCOL cohort, discovering 10,231 and 5,199 TE-expression quantitative trait loci (eQTLs) in normal and tumor tissues, respectively, of which 376 are colorectal cancer specific eQTLs, likely due to methylation changes.

To investigate whether the incidence of triggers, prodromal symptoms, hypersensitivity symptoms accompanying headache and responses to triptans were modified during a continuous 9-month fremanezumab therapy for migraine prophylaxis. We studied 63 patients with high-frequency episodic migraine (HFEM). Enrolled patients received fremanezumab for nine consecutive months before defining the response rates and being stratified into treatment responders (≥50-74% reduction in monthly headache days (MHDs)), super responders (≥75%), partial non-responders (<50%) and super non-responders (<30%).

We sought to assess the efficacy of combining onabotulinumtoxinA (BoNTA) as add-on therapy to carbamazepine or oxcarbazepine in treatment-refractory patients with trigeminal neuralgia (TGN) who failed to respond (less than 30% response rate) to adequate monotherapy. We conducted a retrospective study on 15 patients with a definite diagnosis of TGN, according to the established criteria, and underwent BoNTA as part of their treatment plan. A single BoNTA session was administered subcutaneously, according to patients' perceived zone of pain, at different dosages ranging from 30 to 200 units (mean ± standard deviation: 87.

Article Synopsis
  • The study examines genetic regulation of mRNA, proteins, and metabolites in blood samples from over 3,000 people, revealing that many genetic variants influence multiple molecular traits.* -
  • It finds that there's a strong genetic connection between gene expression and protein levels (66.6%), and shows broad connections across various tissues, highlighting the shared genetic basis for different traits.* -
  • By creating networks of known genetic variants, the research indicates that these variants are more frequently linked to gene expression rather than other molecular traits, helping to clarify the mechanisms behind genetic associations.*

Background: Expression quantitative trait loci (eQTL) studies provide insights into regulatory mechanisms underlying disease risk. Expanding studies of gene regulation to underexplored populations and to medically relevant tissues offers potential to reveal yet unknown regulatory variants and to better understand disease mechanisms. Here, we performed eQTL mapping in subcutaneous (S) and visceral (V) adipose tissue from 106 Greek individuals (Greek Metabolic study, GM) and compared our findings to those from the Genotype-Tissue Expression (GTEx) resource.

Studying the interplay between genetic variation, epigenetic changes, and regulation of gene expression is crucial to understand the modification of cellular states in various conditions, including immune diseases. In this study, we characterize the cell-specificity in three key cells of the human immune system by building cis maps of regulatory regions with coordinated activity (CRDs) from ChIP-seq peaks and methylation data. We find that only 33% of CRD-gene associations are shared between cell types, revealing how similarly located regulatory regions provide cell-specific modulation of gene activity.

Methylmalonic aciduria (MMA) is an inborn error of metabolism with multiple monogenic causes and a poorly understood pathogenesis, leading to the absence of effective causal treatments. Here we employ multi-layered omics profiling combined with biochemical and clinical features of individuals with MMA to reveal a molecular diagnosis for 177 out of 210 (84%) cases, the majority (148) of whom display pathogenic variants in methylmalonyl-CoA mutase (MMUT). Stratification of these data layers by disease severity shows dysregulation of the tricarboxylic acid cycle and its replenishment (anaplerosis) by glutamine.
