Elevated cerebrospinal fluid galectin-3 and associated cytokines after severe traumatic brain injury in patients.

This study aimed to investigate the galectin-3 and associated cytokines levels in the cerebrospinal fluid (CSF) of severe traumatic brain injury (sTBI) patients. Temporal CSF expression of galectin-3 and associated cytokines levels in sTBI patients within 1-week post-injury were studied using the multiplex bead array. STBI patient group was stratified using the Modified Rankin Score (mRS) into 3 groups: mRS 6 (died), mRS 5 (severely disabled) and mRS 1-4 (mild-to-moderately disabled) group. Analysis for bead array data using Kruskal-Wallis test with post hoc Dunn's multiple comparisons test, and temporal changes and correlation analysis using Spearman's correlation were carried out. At day 1 post-injury, CSF galectin-3 and interleukin-6 (IL-6), interleukin-10 (IL-10), cysteine-cysteine motif chemokine ligand-2 (CCL-2), and cysteine-cysteine motif chemokine ligand-20 (CCL-20), but not interleukin-1ß (IL-1ß) and tumor necrosis factor (TNF-α) levels were significantly elevated in mRS 5 group compared to non-TBI controls. Temporal correlation analysis at 1-7 days showed decreased IL-10 level in the mRS 6 group, decreased IL-10 and CCL-2 levels in mRS 5 group, and decreased IL-6, CCL-2, and CCL-20 levels in the mRS 1-4 group. Receiver operating characteristic curve analyses revealed a significant area under the curve for comparison between mRS 6 and mRS 5 groups for galectin-3 and IL-6. No significant differences in sex, age, Glasgow Coma Scale score, C-reactive protein levels and types of TBI-induced hemorrhages were observed between the groups. CSF galectin-3 and associated cytokines, especially IL-6, CCL-2 and CCL-20 levels were different within sub-groups of sTBI patients, suggesting their potential use in sTBI prognostics.

Diversity and representation within the literature on sexual dysfunction in multiple sclerosis: A systematic review.

INTRODUCTION: Sexual dysfunction (SD) is a common and distressing symptom for people living with multiple sclerosis (MS). Populations included in existing studies of SD may not fully reflect the diversity of people living with MS, with important implications for wider applicability. We aimed to evaluate reporting of sex, gender identity, sexual orientation, and ethnicity across studies of SD in MS. METHODS: A systematic search of four databases was performed. Two independent authors evaluated all papers. Reporting of sex and gender identity, sexual orientation, and ethnicity were recorded. RESULTS: A total of 419 papers were reviewed, and 204 studies with 77,902 participants met the criteria for evaluation. Of 204 studies, 98 (48.0%) included both male and female participants; 78 (38.2%) included females only, and 27 (13.2%) males only. In 19 (9.3%) studies, participants were asked their gender. No studies reported asking a two-step question on sex and gender identity. No studies reported including non-binary patients or gender identities other than male or female. No studies reported including intersex patients. Only 10 (4.9%) studies reported the inclusion of homosexual or bisexual participants, or participants from other sexual minority groups. The overwhelming majority of studies (181; 88.7%) did not report ethnicity or race of participants. CONCLUSION: Sex, gender identity, sexual orientation, and ethnicity are poorly reported in studies on SD in MS. These variables must be adequately evaluated to ensure research applies across diverse MS patient populations.
