CASE PRESENTATION: A 34-year-old male presented with C4 complete tetraplegia. Following surgical decompression and initial inpatient rehabilitation, he started consuming MLC901 two capsules three times daily at month 4 post injury for 6 months. He regained considerable neurological recovery following the supplementation. Apart from the improvement in the neurological level of injury, the patient exhibited motor recovery beyond the initial zone of partial preservation up to 24 months post injury.
DISCUSSION: Our findings align with a recent animal study demonstrating MLC901's potential to downregulate Vascular Endothelial Growth Factor (VEGF), a molecule known to increase vascular permeability and exacerbate tissue edema and infarction. In another animal study involving stroke-affected mice, MLC901 demonstrates the ability to promote neurological recovery by regulating the expression of proteins mediating angiogenesis, such as hypoxic inducible factor 1α, erythropoietin, angiopoietins 1 and 2, as well as VEGF. The anecdotal findings from this case report offer preliminary insights into NeuroAiD's potential in facilitating recovery during post-acute and chronic phases of severe SCI, necessitating further exploration.
METHODS: Comprehensive searches of the NCBI database were performed to identify published peer-reviewed articles and genomes of E. faecalis ST476. Each genome was analysed for resistome, virulome, OptrA variant and optrA genetic contexts. A phylogenetic comparison of ST476 genomes with publicly available genomes of other STs was also performed.
RESULTS: Sixty-six E. faecalis ST476 isolates from 15 countries (China, Japan, South Korea, Austria, Denmark, Spain, Czech Republic, Colombia, Tunisia, Italy, Malaysia, Belgium, Germany, United Arab Emirates and Switzerland) mainly of human and animal origin were identified. Thirty available ST476 genomes compared with genomes of 591 STs indicated a progressive radiation of E. faecalis STs starting from ST21. The closest ancestral node for ST476 was ST1238. Thirty E. faecalis ST476 genomes exhibited 3-916 SNP differences. Several antimicrobial resistance and virulence genes were conserved among the ST476 genomes. The optrA genetic context exhibited a high degree of or complete identity to the chromosomal transposon Tn6674. Only three isolates displayed an optrA-carrying plasmid with complete or partial Tn6674. The WT OptrA protein was most widespread in the ST476 lineage.
CONCLUSIONS: Linezolid-resistant optrA-carrying E. faecalis of the clonal lineage ST476 is globally distributed in human, animal and environmental settings. The presence of such an emerging clone can be of great concern for public health. Thus, a One Health approach is needed to counteract the spread and the evolution of this enterococcal clonal lineage.
DESIGN: Preliminary assessment of serum levels of female hormones in women with or without T1DM. Then histological and immunological examinations were carried out on the pancreas, ovaries and uteri at different stages in non-obese diabetic (NOD) and Institute of Cancer Research (ICR) mice, as well as assessment of their fertility. A protein array was carried out to detect the changes in serum inflammatory cytokines. Furthermore, RNA-sequencing was used to identify the key abnormal genes/pathways in ovarian and uterine tissues of female NOD mice, which were further verified at the protein level.
RESULTS: Testosterone levels were significantly increased (P = 0.0036) in female mice with T1DM. Increasing age in female NOD mice was accompanied by obvious lymphocyte infiltration in the pancreatic islets. Moreover, the levels of serum inflammatory factors in NOD mice were sharply increased with increasing age. The fertility of female NOD mice declined markedly, and most were capable of conceiving only once. Furthermore, ovarian and uterine morphology and function were severely impaired in NOD female mice. Additionally, ovarian and uterine tissues revealed that the differentially expressed genes were primarily enriched in metabolism, cytokine-receptor interactions and chemokine signalling pathways.
CONCLUSION: T1DM exerts a substantial impairment on female reproductive health, leading to diminished fertility, potentially associated with immune disorders and alterations in energy metabolism.
