Many children and adolescents around the world suffer from neurocognitive deficits due to chronic disorders, such as Human Immunodeficiency Virus (HIV) and malaria. Resource-limited settings exacerbate the risk of negative cognitive outcomes due to high prevalence of associated disorders, poverty, and limited access to interventions. Current literature does not provide consensus regarding the efficacy of interventions to support children with cognitive impairments in low-resource settings. This research aimed to identify and evaluate interventions for youth with neurocognitive deficits in resource-limited settings. A systematic review of peer-reviewed literature was conducted within five databases (PubMed, Web of Science, CINAHL, PsycInfo, and WHO Index Medicus). Cognitive impairment was broadly defined to be inclusive of aspects of intellectual and cognitive functioning (e.g., working memory, attention, executive function). The income status of the country or countries in which each study was located was determined according to World Bank Income Status. Studies conducted in countries classified as low- or middle-income were included. Since low-resource areas exist within high-income countries, the resource availability within study settings in high-income countries was systematically evaluated for inclusion. The search yielded 19 articles that met all inclusion criteria. Interventions included strategies involving caregiver training, computerized and non-computerized cognitive training, physical activity, and nutritional supplementation. Interventions were administered in medical facilities, educational facilities, or the home. The majority of the interventions targeted the domains of memory and attention. Overall, the efficacy of interventions was inconsistent. Further, results indicated that the relationship between cognitive improvement and intervention types was not consistent across cognitive domains. However, when evaluating studies on an individual basis, some strategies demonstrated clinically- and statistically-significant improvement in cognitive function among specific groups of children. The low article yield highlights that few researchers have evaluated pediatric cognitive support interventions in low-resource contexts. This review suggests support strategies that should be considered for future studies as neurocognitive screening capacity improves in resource-limited settings.

Background Current guidelines recommend surveillance for hepatocellular carcinoma (HCC) in high-risk patients. This high risk is defined by the presence of cirrhosis. However, HCC due to underlying nonalcoholic steatohepatitis (NASH), even without progressing to cirrhosis, is a rising concern. Hence, we aimed to determine the association of HCC with NASH using a large national database. Methods A cross-sectional study was performed using the 2012 National Inpatient Sample. The study group was all adult patients' age 18-90 years who have a diagnosis of NASH which was identified using the International Classification of Diseases 9th version (ICD-9) codes. The control group included the rest of adult individuals without discharge records of NASH. We identified the diagnosis of HCC in both study and control groups using the ICD-9 codes. We calculated the association between NASH and HCC using univariable and multivariate logistic regression. Results Totally, 30 712 524 hospitalizations were included in our study. This cohort included 218 950 patients with NASH (study group) and 30 493 574 patients without NASH (control group). The study group patients aged 57.3 +/- 0.10 years (59.4% females) comparing to 54.5 +/- 0.11 years (57.1% female) in the control group. HCC prevalence in subjects with NASH was 0.50% [95% confidence interval (CI): 0.41-0.59] compared to 0.21% (95% CI: 0.20-0.23) in subjects without NASH (P < 0.001). After adjusting for age, gender, smoking, alcohol use, obesity, hepatitis C virus, hepatitis B virus, hemochromatosis, HIV, cirrhosis and the modified comorbidity index, subjects with NASH were 60% more likely to have HCC than those without NASH (adjusted odds ratio: 1.6, 95% CI: 1.4-1.9, P < 0.001). Conclusion Our study showed that NASH patients are 60% more likely to develop HCC compared with patients without NASH. Close monitoring and even periodical surveillance might be needed.
