ABSTRACT
BACKGROUND AND OBJECTIVES: Safe drinking water and closed sanitation are fundamental to health and are assumed in the United States, however, gaps remain, disproportionately affecting marginalized communities. We sought to describe household sanitation access for children in rural Alabama and local health provider knowledge of sanitation related health concerns. METHODS: Data were collected from self-administered surveys obtained from children enrolled in a larger cross-sectional study to determine soil transmitted helminthiasis prevalence in Alabama, from a survey of health providers from local federally qualified health centers and from a baseline knowledge check of Alabama health providers enrolled in an online sanitation health course. RESULTS: Surveys completed on 771 children (approximately 10% of county pediatric population) revealed less than half lived in homes connected to centralized sewers; 12% reported "straight-pipes," a method of discharging untreated sewage to the ground outside the home, and 8% reported sewage contamination of their home property in the past year. Additionally, 15% of respondents were likely to use well water. The local health providers surveyed did not include routine screening for water and sanitation failures or associated infections. Regional healthcare providers have limited knowledge of soil transmitted helminthiasis. CONCLUSIONS: A significant number of children from rural counties of Alabama with high rates of poverty reside in homes with water and sanitation challenges that predominantly affect African American families. This is an under-recognized health risk by local health providers, and its contribution to well-documented health disparities in this region is poorly understood.

BACKGROUND: Previously, we adapted a mobile health platform (Genia) to the needs of patients and families in a pediatric CF center in the United States. In this feasibility study, we tested the impact of Genia on measures of patient-centered care. METHODS: In a one-group pre-post study with adolescents with CF and caregivers of children with CF, we tested Genia's effect over 6 months on patient satisfaction with chronic illness care (PACIC) and shared decision-making (CollaboRate). Feasibility and acceptability were assessed with exit interviews and app analytics. RESULTS: The intervention included 40 participants: 30 caregivers of children with CF age ≤14 years and 10 patients with CF age ≥15 years. The use of Genia was associated with increased satisfaction with care (p = 0.024), including delivery system and decision support (p = 0.017), goal setting (p = 0.006), and shared decision-making (p<0.001). The use of Genia was associated with nominal improvements in all QOL domains and symptom scales. The platform was feasible, with participants recording more than 4,400 observations (mean 84.2) and submitting 496 weekly reports (mean 13.8) and 70 quarterly reports (mean 1.8), and acceptable (95% retention rate). For participants, the most useful app feature was pre-visit reports (66.7%), and the top symptom trackers were those for cough (23.7%), appetite (21.1%), energy (18.4%), and medicines (18.4%). CONCLUSION: The use of Genia over 6 months was feasible, acceptable, and associated with improved measures of patient-centered care. Study results support wider use of Genia in clinical settings. Efficacy for clinical outcomes should be assessed in a randomized clinical trial.

The one-carbon cycle is composed of four major biologically important molecules: methionine (L-Met), S-adenosylmethionine (SAM), S-adenosylhomocysteine (SAH), and homocysteine (Hcy). In addition to these key metabolites, there are multiple enzymes, vitamins, and cofactors that play essential roles in the cascade of the biochemical reactions that convert one metabolite into another in the cycle. Simultaneous quantitative measurement of four major metabolites can be used to detect possible aberrations in this vital cycle. Abnormalities in the one-carbon cycle might lead to hyper- or hypomethylation, homocystinemia, liver dysfunction, and accumulation of white-matter hyperintensities in the human brain. Previously published methods describe evaluation of several components of the one-carbon cycle, but none to our knowledge demonstrated simultaneous measurement of all four key molecules (L-Met, SAM, SAH, and Hcy). We describe a novel analytical method suitable for simultaneous identification and quantification of L-Met, SAM, SAH, and Hcy with LC-MS/MS. Moreover, we tested this method to identify these metabolites in human plasma collected from patients with multiple sclerosis and healthy individuals. In a pilot feasibility study, our results indicate that patients with multiple sclerosis showed abnormalities in the one-carbon cycle.

Multiple sclerosis (MS) patients make antibodies to heterogeneous nuclear ribonuclear protein A1 (hnRNP-A1), a nucleocytoplasmic protein. We hypothesized this autoimmune reaction might contribute to neurodegeneration. Antibodies from MS patients reacted with hnRNP-A1-'M9', its nuclear translocation sequence. Transfection of anti-M9 antibodies into neurons resulted in neuronal injury and changes in transcripts related to hnRNP-A1 function. Importantly, RNA levels for the spinal paraplegia genes (SPGs) decreased. Changes in SPG RNA levels were confirmed in neurons purified from MS brains. Also, we show molecular interactions between spastin (the encoded protein of SPG4) and hnRNP-A1. These data suggest a link between autoimmunity, clinical phenotype and neurodegeneration in MS.
