Who relocates, where do they move, and why?
The lack of socioeconomic mobility among marginalized populations leads to the concentration of poverty, a long-standing issue in American cities. Empirical studies on neighborhood effects have found that poverty concentration adversely affects the socioeconomic mobility of residents—associated with their economic well-being, employment, education, health, and safety—in lower-income neighborhoods. Through a variety of neighborhood revitalization projects, federal, state, and local governments have put enormous efforts into cutting the vicious cycle of poverty while increasing the socioeconomic mobility of lower-income households. One of these projects, the Choice Neighborhood Initiative, is a recent Federal effort to revitalize distressed public housing sites in American cities. Each project requires its residents to relocate into surrounding neighborhoods during the revitalization process, offering Housing Choice Vouchers (formerly Section 8 Vouchers) to seek subsidized housing in surrounding neighborhoods. While the effects of relocation have been widely studied, less is known about the relocation decisions made by families. This is especially true for programs that rely on housing vouchers, which allow the beneficiaries to decide their relocation destination. We fill this gap by focusing on the relocation process in a Choice Neighborhood Initiative site in Memphis. In particular, this study explores where people relocate and why. We found that even with housing vouchers, one-thirds of the CNI residents moved to mixed-income neighborhoods, and almost one-fourth of the residents chose to stay in their original neighborhood. Secondly, we explored whether the demographic and socioeconomic characteristics of the residents predict their relocation decision. Contrary to our initial expectation, employment status was not significantly associated with the relocation choice. Instead, the educational attainment of household heads and the existence of dependents were significantly associated with the relocation decision. Perhaps most interesting, we find that while perceptions of neighborhood safety are associated with moves to similar-income neighborhoods, perceptions of home safety are associated with moves to higher-income neighborhoods. The present results are significant in at least two respects. First, these findings may help practitioners, such as case managers in the Choice Neighborhood Initiative, to understand various attributes of the project beneficiaries among residents who different relocation decisions. For better implementation of the projects, practitioners may need to adopt different approaches and strategies when providing services to certain groups of residents. For example, given the importance of dependents in relocation decisions, case managers may need to consider ways to help their clients relocate to neighborhoods with high-quality schools. Second, the findings have important implications for those who develop inferential models for evaluating the impact of relocation on the original residents’ lives. The heterogeneity of residents in various relocation decision groups calls for more sophisticated empirical model designs to resolve the endogenous relationship between targeted families’ characteristics and their relocation choices
Engaging Underrepresented Populations
Report completed by students enrolled in PA 5253: Planning Participation Processes, taught by Dr. Carissa Schively Slotterback in fall 2013.This project was completed as part of the 2013-2014 Resilient Communities Project (rcp.umn.edu) partnership with the City of North St. Paul. The City of North St. Paul sought to build on existing neighborhood crime watch organizations to engage and empower neighborhood residents to keep their neighborhoods safe, livable, and vibrant, while developing a clearer sense of resident issues and priorities. Project lead Paul Ammerman collaborated with students in PA 5253: Planning Participation Processes, to create a participation plan targeted at engaging underrepresented populations. The students provided the City with an engagement plan and specific recommendations for communication and maintaining relationships. This is one of two reports completed on this topic for this course. The students' final report is available.This project was supported by the Resilient Communities Project (RCP), a program at the University of Minnesota whose mission is to connect communities in Minnesota with U of MN faculty and students to advance local sustainability and resilience through collaborative, course-based projects.

Structural and Intermediary Social Determinants of Health and the Emotional and Behavioral Health of US Children
Children grow up in homes where varying environmental and socioeconomic contexts have a bearing on their emotional and behavioral health (EBH). This study used data from a representative sample of the child supplement of the US National Health Information Survey (NHIS) and applied the social determinants of health (SDoH) framework to explore factors associated with child EBH. We conducted a path analysis of the child’s EBH measured by the strengths and difficulties questionnaire (SDQ) from their macro and socioeconomic contexts, e.g., policy, household, and other health system risk factors. For children in the sample, aged 4 to 17 years old (n = 9205), most path relationships to child SDQ scores were statistically significant. The total effects from a child’s visit to a mental health specialist (0.28) and child’s age (0.22) had the highest coefficients to child SDQ scores. A modified model showed a better fit with X2 (4) = 22.124, RMSEA = 0.021, and 90% CI [0.013–0.03], CFI = 0.98. Findings indicate that child factors such as being older, the use of mental healthcare services, and family socioeconomic status were significantly associated with EBH, calling attention to the need for more responsive policy and behavioral health interventions that address household/familial and child-level factors, critical determinants of child wellbeing
Examining the Utility of the Early Childhood Development Index (ECDI) among Children in the Nigeria Context
An estimated 6 million children under the age of five in Nigeria (out of nearly 31 million) risk not reaching their full developmental potential. The dearth of context-relevant measures poses a challenge to the planning and implementation of effective interventions. This study assesses the utility of the Early Childhood Development Index (ECDI) in Nigeria. We used the Multiple Indicator Cluster Surveys to track progress among 3- to 4-year-old children (n = 11,073); 3-year-old, 51%; female, 49%. Using random calibration samples, the results from psychometric tests indicate that while over half of the children were on track in their development based on the ECDI, the instrument had low to average internal consistency and weak face validity, suggesting an inadequacy in capturing ECD information of value. At the outset of the launch of the new ECDI2030, the results of this study point to the need for continued discourse and advocacy for the use of culturally appropriate measures of child development, and a child-centered community engagement approach. This is essential in ensuring accountability and responsive interventions for the children served and their families
Genetic architecture distinguishes systemic juvenile idiopathic arthritis from other forms of juvenile idiopathic arthritis: Clinical and therapeutic implications
Objectives Juvenile idiopathic arthritis (JIA) is a heterogeneous group of conditions unified by the presence of chronic childhood arthritis without an identifiable cause. Systemic JIA (sJIA) is a rare form of JIA characterised by systemic inflammation. sJIA is distinguished from other forms of JIA by unique clinical features and treatment responses that are similar to autoinflammatory diseases. However, approximately half of children with sJIA develop destructive, long-standing arthritis that appears similar to other forms of JIA. Using genomic approaches, we sought to gain novel insights into the pathophysiology of sJIA and its relationship with other forms of JIA. Methods We performed a genome-wide association study of 770 children with sJIA collected in nine countries by the International Childhood Arthritis Genetics Consortium. Single nucleotide polymorphisms were tested for association with sJIA. Weighted genetic risk scores were used to compare the genetic architecture of sJIA with other JIA subtypes. Results The major histocompatibility complex locus and a locus on chromosome 1 each showed association with sJIA exceeding the threshold for genome-wide significance, while 23 other novel loci were suggestive of association with sJIA. Using a combination of genetic and statistical approaches, we found no evidence of shared genetic architecture between sJIA and other common JIA subtypes. Conclusions The lack of shared genetic risk factors between sJIA and other JIA subtypes supports the hypothesis that sJIA is a unique disease process and argues for a different classification framework. Research to improve sJIA therapy should target its unique genetics and specific pathophysiological pathways
Increased Expression of the Auxiliary β(2)-subunit of Ventricular L-type Ca(2+) Channels Leads to Single-Channel Activity Characteristic of Heart Failure
BACKGROUND: Increased activity of single ventricular L-type Ca(2+)-channels (L-VDCC) is a hallmark in human heart failure. Recent findings suggest differential modulation by several auxiliary β-subunits as a possible explanation. METHODS AND RESULTS: By molecular and functional analyses of human and murine ventricles, we find that enhanced L-VDCC activity is accompanied by altered expression pattern of auxiliary L-VDCC β-subunit gene products. In HEK293-cells we show differential modulation of single L-VDCC activity by coexpression of several human cardiac β-subunits: Unlike β(1) or β(3) isoforms, β(2a) and β(2b) induce a high-activity channel behavior typical of failing myocytes. In accordance, β(2)-subunit mRNA and protein are up-regulated in failing human myocardium. In a model of heart failure we find that mice overexpressing the human cardiac Ca(V)1.2 also reveal increased single-channel activity and sarcolemmal β(2) expression when entering into the maladaptive stage of heart failure. Interestingly, these animals, when still young and non-failing (“Adaptive Phase”), reveal the opposite phenotype, viz : reduced single-channel activity accompanied by lowered β(2) expression. Additional evidence for the cause-effect relationship between β(2)-subunit expression and single L-VDCC activity is provided by newly engineered, double-transgenic mice bearing both constitutive Ca(V)1.2 and inducible β(2) cardiac overexpression. Here in non-failing hearts induction of β(2)-subunit overexpression mimicked the increase of single L-VDCC activity observed in murine and human chronic heart failure. CONCLUSIONS: Our study presents evidence of the pathobiochemical relevance of β(2)-subunits for the electrophysiological phenotype of cardiac L-VDCC and thus provides an explanation for the single L-VDCC gating observed in human and murine heart failure
JAK1/2 inhibition with baricitinib in the treatment of autoinflammatory interferonopathies
BACKGROUND. Monogenic IFN-mediated autoinflammatory diseases present in infancy with systemic inflammation, an IFN response gene signature, inflammatory organ damage, and high mortality. We used the JAK inhibitor baricitinib, with IFN-blocking activity in vitro, to ameliorate disease. METHODS. Between October 2011 and February 2017, 10 patients with CANDLE (chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperatures), 4 patients with SAVI (stimulator of IFN genes-associated [STING-associated] vasculopathy with onset in infancy), and 4 patients with other interferonopathies were enrolled in an expanded access program. The patients underwent dose escalation, and the benefit was assessed by reductions in daily disease symptoms and corticosteroid requirement. Quality of life, organ inflammation, changes in IFN-induced biomarkers, and safety were longitudinally assessed. RESULTS. Eighteen patients were treated for a mean duration of 3.0 years (1.5-4.9 years). The median daily symptom score decreased from 1.3 (interquartile range [IQR], 0.93-1.78) to 0.25 (IQR, 0.1-0.63) (P < 0.0001). In 14 patients receiving corticosteroids at baseline, daily prednisone doses decreased from 0.44 mg/kg/day (IQR, 0.31-1.09) to 0.11 mg/kg/day (IQR, 0.02-0.24) (P < 0.01), and 5 of 10 patients with CANDLE achieved lasting clinical remission. The patients' quality of life and height and bone mineral density Z-scores significantly improved, and their IFN biomarkers decreased. Three patients, two of whom had genetically undefined conditions, discontinued treatment because of lack of efficacy, and one CANDLE patient discontinued treatment because of BK viremia and azotemia. The most common adverse events were upper respiratory infections, gastroenteritis, and BK viruria and viremia. CONCLUSION. Upon baricitinib treatment, clinical manifestations and inflammatory and IFN biomarkers improved in patients with the monogenic interferonopathies CANDLE, SAVI, and other interferonopathies. Monitoring safety and efficacy is important in benefit-risk assessment
Plasma membrane proteomes of differentially matured dendritic cells identified by LC-MS/MS combined with iTRAQ labelling
AbstractDendritic cells (DCs) play a pivotal role in polarising Th lymphocyte subsets but it is unclear what molecular events occur when DCs generate Th2-type responses. Here, we analysed plasma membrane-enriched fractions from immature, pro-Th1 and pro-Th2 DCs and used a combination of iTRAQ labelling and LC–MS/MS to quantify changes in the proteomes. Analysis was performed on triplicate biological samples and changes verified by flow cytometry. MHC class II molecules and CD29 were up-regulated in pro-Th1 DCs whilst CD18 and CD44 were up-regulated in pro-Th2 DCs. One of the most down-regulated molecules in pro-Th1 DCs was YM-1 whilst the greatest decrease in pro-Th2 DCs was NAP-22. Other molecules up-regulated in pro-Th2 DC compared to pro-Th1 DCs included some potentially involved in protein folding during antigen processing (clathrin and Rab-7), whilst other non-membrane proteins such as enzymes/transporters related to cell metabolism (malate dehydrogenase, pyruvate kinase, and ATPase Na+/K+) were also recorded. This suggests that pro-Th2 DCs are more metabolically active while pro-Th1 DCs have a mature ‘end state’. Overall, although several molecules were preferentially expressed on pro-Th2 DCs, our proteomics data support the view of a ‘limited maturation’ of pro-Th2 DCs compared to pro-Th1 DCs
