RESUMEN
African countries continue to neglect the effects of mental illness on their communities. Identifying barriers to treatment and developing mitigation strategies is essential to address the burden of mental illness within Africa. We searched PubMed, Medline, PSYCHInfo, ERIC, Cochrane Library, ClinicalTrials.gov, and reference lists through June 2020. Studies addressed barriers to mental illness treatment affecting patients and/or their care team. Data was extracted using a standardized data collection form. Three independent, blinded reviewers extrapolated qualitative and quantitative data. Themes were summarized qualitatively. Thirteen studies reflecting urban and rural settings qualified for review. Participants were 17 to 58 years old. Males accounted for 49.9% of the study population. Barriers were categorized as attitudinal, economic, physical, political, and infrastructural. Attitudinal barriers were most prevalent; infrastructural barriers were least discussed. Policy and infrastructural implementations would mitigate interconnected barriers and improve health and wellbeing within Africa.

RESUMEN
Evidence for putative pathophysiological mechanisms of autism spectrum disorder (ASD), including peripheral inflammation, blood-brain barrier disruption, white matter alterations, and abnormal synaptic overgrowth, indicate a possible involvement of neuroinflammation in the disorder. Neuroinflammation plays a role in the development and maintenance of the dendritic spines involved in glutamatergic and GABAergic neurotransmission, and also influences blood-brain permeability. Cytokines released from microglia can impact the length, location or organization of dendritic spines on excitatory and inhibitory cells as well as recruit and impact glial cell function around the neurons. In this study, gene expression levels of anti- and pro-inflammatory signaling molecules, as well as oligodendrocyte and astrocyte marker proteins, were measured in both gray and white matter tissue in the anterior cingulate cortex from ASD and age-matched typically developing (TD) control brain donors, ranging from ages 4 to 37 years. Expression levels of the pro-inflammatory gene, HLA-DR, were significantly reduced in gray matter and expression levels of the anti-inflammatory gene MRC1 were significantly elevated in white matter from ASD donors as compared to TD donors, but neither retained statistical significance after correction for multiple comparisons. Modest trends toward differences in expression levels were also observed for the pro-inflammatory (CD68, IL1ß) and anti-inflammatory genes (IGF1, IGF1R) comparing ASD donors to TD donors. The direction of gene expression changes comparing ASD to TD donors did not reveal consistent findings implicating an elevated pro- or anti-inflammatory state in ASD. However, altered expression of pro- and anti-inflammatory gene expression indicates some involvement of neuroinflammation in ASD.

LAY SUMMARY: The anterior cingulate cortex is an integral brain region in modulating social behaviors including nonverbal communication. The study found that inflammatory gene expression levels were altered in this brain region. We hypothesize that the inflammatory changes in this area could impact neuronal function. The finding has future implications in using these molecular markers to identify potential environmental exposures and distinct cell differences in autism.
