Cocaine use disorder (CUD) is a substance use disorder (SUD) characterized by compulsion to seek, use and abuse of cocaine, with severe health and economic consequences for the patients, their families and society. Due to the lack of successful treatments and high relapse rate, more research is needed to understand this and other SUD. Here, we present the SUDMEX CONN dataset, a Mexican open dataset of 74 CUD patients (9 female) and matched 64 healthy controls (6 female) that includes demographic, cognitive, clinical, and magnetic resonance imaging (MRI) data. MRI data includes: 1) structural (T1-weighted), 2) multishell high-angular resolution diffusion-weighted (DWI-HARDI) and 3) functional (resting state fMRI) sequences. The repository contains unprocessed MRI data available in brain imaging data structure (BIDS) format with corresponding metadata available at the OpenNeuro data sharing platform. Researchers can pursue brain variability between these groups or use a single group for a larger population sample.
Fibromyalgia is a chronic condition characterized by widespread pain, as well as numerous symptoms related to central sensitization such as: fatigue, cognitive disturbances, constipation/diarrhea and sensory hypersensitivity. Furthermore, depression and anxiety are prevalent comorbidities, accompanied by emotion processing and regulation difficulties. Although fibromyalgia physiopathology is still not fully understood, neuroimaging research methods have shown brain structural and functional alterations as well as neuroinflammation abnormalities. We believe that open access to data may help fibromyalgia research advance more. Here, we present an open dataset of 33 fibromyalgia female patients and 33 paired healthy controls recruited from a Mexican population. Dataset includes demographic, clinical, behavioural and magnetic resonance imaging (MRI) data. The MRI data consists of: structural (T1- and T2- weighted) and functional (task-based and resting state) sequences. The task was an emotion processing and regulation task based on visual stimuli. The MRI data contained in the repository are unprocessed, presented in Brain Imaging Data Structure (BIDS) format and available on the OpenNeuro platform for future analysis.

IntroductionHigh levels of alexithymia as well as low scores on assertiveness have been described in patients with chronic pain and headache.ObjectivesTo determine alexithymia and assertiveness scores and to explore their association with headache impact, in primary chronic headache patients.AimsThis study aims to advance knowledge of the emotional expressiveness in headache impact.MethodsIn a sample of 62 outpatients, we used the Toronto Alexithymia Scale (TAS-20), the Rathus Assertiveness Scale and the Headache Impact Test (HIT-6) and applied the Pearson correlation index.Results77.4% of women, 36.3 years mean age. The most prevalent diagnoses are migraine combined with tension type headache (33.9%), migraine alone (32.3%) and tension-type headache alone (22.6%). Most of the patients have not any psychiatric comorbidity (77.8%). We observe a direct linear relationship and statistically significant difference, between the total impact of headache and the total score of alexithymia (r = 0.27 p = 0.03) and there is an inverse correlation between the impact of headache and the total score of the scale of assertiveness, not statistically significant (r = −0.004 p = 0.97).Discriminated by diagnostic groups, we found that the association between assertiveness and headache impact remains only in patients with migraine alone, while that between alexithymia and headache impact is preserved in all subgroups.ConclusionTwo indirect measures of the difficulties in emotional expressiveness such as alexithymia and assertiveness, show the expected association with headache impact. The sample size can influence some of the correlations not statistically significant.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
