GRAND PLAN: Safety and Efficacy of Glecaprevir/Pibrentasvir for the Treatment of Hepatitis C Virus Infection Among People Initially Disengaged From Health Care Who Use Drugs-A Systematic Multidisciplinary Approach

Background

GRAND PLAN is a prospective, open-label, phase 4 study. Based at a single center and with a single arm, GRAND PLAN evaluated the safety and efficacy of an 8-week course of glecaprevir/pibrentasvir (G/P) among active drug users with hepatitis C virus (HCV) infection in a population enriched for factors that may reduce treatment uptake and success, such as disengagement from health care and unstable housing.

Methods

Participants were ≥19 years old and actively using drugs and were confirmed viremic, noncirrhotic, and HCV treatment naive. All participants provided informed consent before any study procedures. They received G/P for 8 weeks within a multidisciplinary model of care, with daily, weekly, or monthly dispensing of medications to optimize adherence.

Results

We identified 117 eligible patients with a median age of 46 years (range, 22-75): 27% were female, 21.4% were Indigenous, 48.7% were unstably housed, and 95.7% were active drug users (94.9% fentanyl). One patient did not start treatment, and 4 underwent <1 week of treatment, leaving 112 completed treatments with 94.6% picking up medications weekly. HCV RNA was undetectable at the end of treatment in all 112 patients. One died of unknown causes shortly after treatment. A cure was demonstrated in 108 of 111 (97.3%) cases at the SVR12 time point (sustained virologic response at ≥12 weeks); the other 3 experienced virologic relapse. Considering the entire cohort, the intent-to-treat success rate was 92.3% (108/117). HCV reinfection was documented at SVR24 in 5 cases, 2 of which were successfully retreated.

Conclusions

GRAND PLAN demonstrates that administration of an 8-week course of G/P to inner-city residents with HCV infection leads to a cure >95%. With a short course of treatment, G/P is an attractive option for this population in helping us achieve the World Health Organization's HCV objectives by 2030.

The Effectiveness of an Empowerment Education Intervention for Substance Use Reduction among Inner-City Adolescents in Nigeria

(1) Background: Substance use among inner-city adolescents is at an alarming rate in Nigeria. Despite their high exposure to this risk, limited experimental tests have been conducted on prevention programs. (2) Methods: This study investigates the effectiveness of an empowerment education intervention in reducing the risk of substance use in Abuja's inner-city adolescents. Random selection placed adolescents into intervention and control conditions, and assessment was conducted at baseline, post-test, and 3-months follow-up intervention. After pre-test, the intervention group engaged in an empowerment education intervention of 11 sessions. (3) Results: In a post-test of three months, results show significant and positive changes among adolescents in substance use, including a notable reduction in positive attitudes toward drugs. In other words, the results showed adolescents reported less depression and substance use as well as higher peer support, parental support, social competence, and self-esteem at post-test and 3-month follow-ups as compared to the pre-intervention period. In addition, at both post-test and the 3-month follow-up, the intervention group performed better than the control group on peer support, parental support, social competence, and self-esteem. (4) Conclusions: This study presents a new indication that the empowerment education intervention effectively reduces substance use among Nigeria's inner-city adolescents.

Safety and Inner City Neighborhood Change: Student and Teacher Perspectives

The introduction of mixed-income communities in public housing neighborhoods is a common revitalization strategy in metropolitan areas in North America. This study investigates student and teacher perspectives on safety in a Canadian inner city and marginalized neighborhood undergoing revitalization, alongside the redesign of a local school. The displacement of families and students, tied to housing relocation and student school mobility, resulted in increased concern around bullying, school safety, and displacement of place-based familiarity and social bonds. While most students felt safe at school, they were acutely aware of community level violence, criminal and gang activity in the neighborhood, and racial stereotyping. Students were also generally skeptical that revitalization would address the root causes of violence. The findings support the importance of including children's voices when planning, implementing, and evaluating policy initiatives that directly affect their lives.

What Family Circumstances, During COVID-19, Impact on Parental Mental Health in an Inner City Community in London?

The introduction of lockdown due to a public health emergency in March 2020 marked the beginning of substantial changes to daily life for all families with young children. Here we report the experience of families from London Borough of Tower Hamlets with high rates of poverty and ethnic and linguistic diversity. This inner city community, like communities worldwide, has experienced a reduction or closure in access to education, support services, and in some cases, a change in or loss of income, job, and food security. Using quantitative survey items (N = 992), we examined what differences in family circumstances, for mothers and fathers of young children aged 0-5 living in Tower Hamlets, during March 2020 to November 2020, were associated with their mental health status. We measure parental mental health using symptoms of depression (self-report: Patient Health Questionnaire depression scale: PHQ-8), symptoms of anxiety levels (self-report: General Anxiety Disorder: GAD-7), and perceptions of direct loneliness. We find parental mental health difficulties are associated with low material assets (financial security, food security, and children having access to outside space), familial assets (parents time for themselves and parent status: lone vs. cohabiting), and community assets (receiving support from friends and family outside the household). South Asian parents and fathers across ethnicities were significantly more likely to experience mental health difficulties, once all other predictors were accounted for. These contributing factors should be considered for future pandemics, where restrictions on people's lives are put in place, and speak to the importance of reducing financial insecurity and food insecurity as a means of improving the mental health of parents.

Development of nasal allergen challenge with cockroach in children with asthma

BACKGROUND

Nasal allergen challenge (NAC) could be a means to assess indication and/or an outcome of allergen-specific therapies, particularly for perennial allergens. NACs are not commonly conducted in children with asthma, and cockroach NACs are not well established. This study's objective was to identify a range of German cockroach extract doses that induce nasal symptoms and to assess the safety of cockroach NAC in children with asthma.

METHODS

Ten adults (18-37 years) followed by 25 children (8-14 years) with well-controlled, persistent asthma and cockroach sensitization underwent NAC with diluent followed by up to 8 escalating doses of cockroach extract (0.00381-11.9 µg/mL Bla g 1). NAC outcome was determined by Total Nasal Symptom Score (TNSS) and/or sneeze score. Cockroach allergen-induced T-cell activation and IL-5 production were measured in peripheral blood mononuclear cells.

RESULTS

67% (6/9) of adults and 68% (17/25) of children had a positive NAC at a median response dose of 0.120 µg/mL [IQR 0.0380-0.379 µg/mL] of Bla g 1. Additionally, three children responded to diluent alone and did not receive any cockroach extract. Overall, 32% (11/34) were positive with sneezes alone, 15% (5/34) with TNSS alone, and 21% (7/34) with both criteria. At baseline, NAC responders had higher cockroach-specific IgE (P = .03), lower cockroach-specific IgG/IgE ratios (children, P = .002), and increased cockroach-specific IL-5-producing T lymphocytes (P = .045). The NAC was well tolerated.

CONCLUSION

We report the methodology of NAC development for children with persistent asthma and cockroach sensitization. This NAC could be considered a tool to confirm clinically relevant sensitization and to assess responses in therapeutic studies.

Improving teacher comfort and self-efficacy in asthma management

Background: Asthma is common among urban school-age children. Though teachers should be prepared to assist children during an asthma attack, studies show they lack self-efficacy in managing asthma.Objective: To assess feasibility of implementing an asthma workshop for elementary school teachers, describe themes of questions raised, and determine workshop's impact on teachers' comfort and self-efficacy in asthma management.Methods: We developed and implemented an asthma workshop for teachers from four Bronx elementary schools (2012-2014). Teachers completed a questionnaire evaluating their comfort and self-efficacy in asthma management before and after the workshop. Questions asked during the sessions were recorded and analyzed for themes. Paired t-test and McNemar tests compared before/after scores.Results: 65 out of 70 teachers (92.9%) participated in the educational sessions. Teachers asked questions about school policy for inhalers, medication administration guidelines, and physical activity and asthma. 64/65 (98.5%) teachers completed pre/post surveys (mean age 39.7 years; mean years at the school 8.0). Post-intervention, more teachers reported knowing how to manage an asthma attack (93.8% vs. 64.1%, p < .0001); and felt comfortable assessing (50.8% vs. 30.8%, p = 0.019) and handling an asthma attack (52.3% vs. 33.8%, p = .023). The overall mean self-efficacy score increased post-intervention (43.0 vs. 38.1, p < .0001), as did 8/12 individual self-efficacy items. Post-workshop, 95.3% of teachers agreed that teacher in-service asthma education should be done annually.Conclusions: An asthma workshop was successfully implemented in the school setting and improved teacher comfort and self-efficacy in managing asthma. Annual training may improve teachers' confidence in assisting students with asthma.

Screen Time Engagement Is Increased in Urban Children With Asthma

Physical activity in children has been shown to play a role in its relationship to asthma, both in terms of prevalence and incidence. One measure of physical activity in children is sedentary behavior, which might be measured by the degree of engagement with media electronic screens. We found that children with asthma, as compared with children without asthma, engage in significantly more hours of screen time (median 35 vs 26 h/wk, P = .004). In this birth cohort, those who developed a diagnosis of asthma at 8 years of age were significantly more engaged in electronic screen time than their peers. No other clinical or lifestyle behaviors were significantly associated with a diagnosis of asthma. Further study will be needed to determine directionality of this finding.

Poor Adherence With Medication Refill and Medical Supplies Maintenance as Risk Factors for Inpatient Asthma Admission in Children

Background. Asthma results in significant pediatric hospitalizations in the inner city. Many asthmatic children were admitted to our hospital as a result of lack of medications or medical supplies that had been previously prescribed ("ran out," "broken," or "lost"). Objective. To identify the incidence of children admitted for asthma because of lack of prescribed medications/supplies and to assess risk factors for poor adherence between groups. Methods. This was a prospective chart review of 200 asthmatic children admitted to Children's Hospital of Michigan, Detroit. The data included asthma severity, lack of prescribed medications/medical supplies, and outpatient management. Results. In all, 35.5% or 71/200 of asthmatic children admitted had lack of prescribed medication/supplies (9% lacked both). The most common deficiency was β2-agonist (20.5%; 41/200). Teenagers had the highest lack of medications/medical supplies (55.6%; 5/9) compared with toddlers (17.2%; 16/93) and preschoolers (17.9%; 5/28). Patients with severe persistent asthma had a higher incidence of lacking medicine (31.8%; 7/22) compared with 25% (14/56) with moderate persistent asthma and 23.4% (15/64) of mild asthmatics. We found the lack of asthma medical supplies, including nonfunctioning or lost nebulizers/spacers, in 44.4% (4/9) of teenagers, 17.2% (16/93) of toddlers, and 21.4% (6/28) of preschool-aged children. We found no significant difference in these deficiencies whether patients were managed by asthma specialists or primary care providers. Conclusions. Significant numbers of asthmatic children admitted reported lack of prescribed medications/medical supplies. The most severe asthmatics were most likely to run out of medications. Interventions targeted at these deficiencies may avoid hospitalizations.

Urban residence, neighborhood poverty, race/ethnicity, and asthma morbidity among children on Medicaid

BACKGROUND

Although poor-urban (inner-city) areas are thought to have high asthma prevalence and morbidity, we recently found that inner cities do not have higher prevalent pediatric asthma. Whether asthma morbidity is higher in inner-city areas across the United States is not known.

OBJECTIVE

This study sought to examine relationships between residence in poor and urban areas, race/ethnicity, and asthma morbidity among children with asthma who are enrolled in Medicaid.

METHODS

Children aged 5 to 19 enrolled in Medicaid in 2009 to 2010 were included. Asthma was defined by at least 1 outpatient or emergency department (ED) visit with a primary diagnosis code of asthma over the 2-year period. Urbanization status was defined at the county level and neighborhood poverty at the zip-code level. Among children with asthma, logistic models were created to examine the effects of urbanization, neighborhood poverty, and race/ethnicity on rates of asthma outpatient visits, ED visits, and hospitalizations.

RESULTS

This study included 16,860,716 children (1,534,820 with asthma). Among children enrolled in Medicaid, residence in inner-city areas did not confer increased risk of prevalent asthma in either crude or adjusted analyses, but it was associated with significantly more asthma-related ED visits and hospitalizations among those with asthma in crude analyses (risk ratio, 1.48; 95% CI, 1.24-1.36; and 1.97; 95% CI, 1.50-1.72, respectively) and when adjusted for race/ethnicity, age, and sex (adjusted risk ratio, 1.23; 95% CI, 1.08-1.15; and 1.62; 95% CI, 1.26-1.43). Residence in urban or poor areas and non-Hispanic black race/ethnicity were all independently associated with increased risk of asthma-related ED visits and hospitalizations.

CONCLUSIONS

Residence in poor and urban areas is an important risk factor for asthma morbidity, but not for prevalence, among low-income US children.

Relationships among Maternal Stress and Depression, Type 2 Responses, and Recurrent Wheezing at Age 3 Years in Low-Income Urban Families

RATIONALE

Maternal depression and prenatal and early life stress may influence childhood wheezing illnesses, potentially through effects on immune development.

OBJECTIVES

To test the hypothesis that maternal stress and/or depression during pregnancy and early life are associated with recurrent wheezing and aeroallergen sensitivity and altered cytokine responses (enhanced type 2 or reduced virus-induced cytokine responses) from stimulated peripheral blood mononuclear cells at age 3 years.

METHODS

URECA (Urban Environment and Childhood Asthma) is a birth cohort at high risk for asthma (n = 560) in four inner cities. Maternal stress, depression, and childhood wheezing episodes were assessed by quarterly questionnaires beginning at birth. Logistic and linear regression techniques were used to examine the relation of maternal stress/depression to recurrent wheezing and peripheral blood mononuclear cell cytokine responses at age 3 years.

MEASUREMENTS AND MAIN RESULTS

Overall, 166 (36%) children had recurrent wheeze at age 3 years. Measures of maternal perceived stress at Years 2 and 3 were positively associated with recurrent wheeze (P < 0.05). Maternal depression (any year) was significantly associated with recurrent wheezing (P ≤ 0.01). These associations were also significant when considered in a longitudinal analysis of cumulative stress and depression (P ≤ 0.02). Neither stress nor depression was significantly related to aeroallergen sensitization or antiviral responses. Contrary to our original hypothesis, prenatal and Year 1 stress and depression had significant inverse associations with several type 2 cytokine responses.

CONCLUSIONS

In urban children at high risk for asthma, maternal perceived stress and depression were significantly associated with recurrent wheezing but not increased atopy or reduced antiviral responses.

Oral health status and possible explanatory factors of an inner-city low-income community

Background/purpose

Individuals with low income bear a number of health challenges to healthcare services. Vancouver's Downtown Eastside (DTES) is known to be a low-income community in a metropolitan city. Because it is difficult to reach, the oral health (OH) status of these residents is unknown. The objectives of this study are (1) to design a tool and strategy to collect OH information in a low-income community, (2) to characterize the OH status and related factors among low-income adults, and (3) to identify the explanatory factors for their OH status.

Materials and methods

Mobile screening clinics were established in the gathering centers of the DTES, and those of 19 years of age or older were recruited. Data were collected through survey interviews and clinical examinations. Potential explanatory factors were investigated by regression analysis.

Results

The 356 screened participants were mostly males, middle-aged, less educated, and living with low income (≤CAD$20,000/y). About 80% had dental coverage, mostly from public programs (94%). Many (86%) perceived a dental need. Among dentate participants (n = 306), on average, 3.8 decayed, 8.6 missing, 4.9 filled teeth, and a care index of 41.5% were observed. Social factors (barriers to care and length of DTES residence), dental hygiene (brushing/flossing), and personal (hepatitis C virus infection/methadone usage) factors contributed to their care index level.

Conclusion

This is the first time that comprehensive information regarding OH status has been collected from a low-income, inner-city community in Canada. Further investigations in the challenges and needs in accessing dental care may develop solutions for better OH in similar communities.

The Role of Red Cell Distribution Width as a Predictor of Mortality for Critically Ill Patients in an Inner-city Hospital

Background:

Red cell distribution width (RDW) is a measure of the variation in the red blood cell volume that is usually recorded as a part of the standard complete blood cell count. Recent studies have demonstrated the prognostic value of RDW in many different clinical settings. The objective of this research study is to investigate the independent association of RDW with 30-day mortality in Intensive Care Unit (ICU) patients.

Methods:

One hundred and fifty-six patients admitted to the ICU of our hospital between July 2009 and June 2011 were included in our study. Out of 156 patients, 124 survived the hospital stay. The data on patient's demographics, interventions done in ICU, and their comorbidities were collected. Baseline variables and the RDW value were compared between survivors and nonsurvivors. The cutoff point for RDW used for the comparison was 15.75. Both univariable and multivariable analyses were done. P < 0.05 was considered statistically significant.

Results:

In the univariable analysis of the study between survivors and nonsurvivors, the median RDW was 17.20 for nonsurvivors, implying statistical significance (P = 0.007). In multivariable analysis, RDW remained significantly associated with inpatient mortality. The receiver operating characteristic is 0.656 (P = 0.007), with an optimal cutoff of 15.75 for RDW. At the cutoff of RDW, i.e., 15.75, the sensitivity and specificity for inpatient mortality was 71% and 89%, respectively.

Conclusion:

In critically ill ICU patients, RDW is an independent predictor of 30-day mortality. Taking into consideration the fact that RDW is routinely measured in complete blood count with no additional cost, this can serve as an “inexpensive prognostic marker” in critically ill patients.

Burns from ignited household aerosols in the kitchen: a case series

Aerosol sprays are commonly used products in daily living. Aerosols in kitchen products have prompted for use of 'food grade' or chemically inert propellants; however, they commonly contain gases or gaseous mixtures such as butane, propane and dimethyl ether that are flammable. When such sprays are used near heat sources, such as kitchen appliances, combustibles in these products can result in ignition and burn injury. Given the ubiquity of such sprays, surprisingly burns sustained from household aerosols are not characterised in the literature. We conducted a retrospective search of all burn patients treated at our hospital which contains a burn unit. Three patients were identified with burn wounds due to household aerosol sprays. All three occurred in the kitchen. and were characterized as first-degree and second-degree burns over the head and neck or upper extremities with one requiring inpatient admission. Where it may be perceived a cause of minor injury, household aerosol burns may result in significant burn injury and hospital admission. Household aerosols and burn injury are reviewed.

Asthma and subjective sleep disordered breathing in a large cohort of urban adolescents

OBJECTIVE

Sleep disordered breathing (SDB) has not been well studied in urban adolescents with asthma in community settings. Nor has the association of SDB symptoms and asthma severity been studied. We characterized self-reported symptoms suggesting SDB and investigated the association of SDB symptoms, probable asthma, and asthma severity.

METHODS

9,565 adolescents from 21 inner-city high schools were screened for an asthma intervention study. Students reported on symptoms suggesting SDB using questions from the 2007 NHANES, if they were ever diagnosed with asthma, and on asthma symptoms. Using generalized linear mixed models with logit link with school as a random intercept and adjusting for age, gender, and race/ethnicity, we examined associations of SDB symptoms, and demographic characteristics, probable asthma, and asthma severity.

RESULTS

12% reported SDB symptoms. Older and bi-racial participants (compared to Caucasian) had higher odds of symptoms suggesting SDB (p <.001). Compared to those without probable asthma, adolescents with probable asthma had 2.63 greater odds of reporting SDB symptoms (p <.001). Among those with probable asthma, the odds of reporting SDB symptoms increased with asthma severity. When exploring daytime severity and severity due to night wakening separately, results were similar. All results remained significant when controlling for age, gender, and ethnicity.

CONCLUSIONS

In a large urban community cohort of predominately ethnic minority adolescents, self-reported SDB symptoms were associated with probable asthma and increased asthma severity. This study highlights the importance of SDB as a modifiable co-morbidity of asthma.

The nasal methylome and childhood atopic asthma

BACKGROUND

Given the strong environmental influence on both epigenetic marks and allergic asthma in children, the epigenetic alterations in respiratory epithelia might provide insight into allergic asthma.

OBJECTIVE

We sought to identify DNA methylation and gene expression changes associated with childhood allergic persistent asthma.

METHODS

We compared genomic DNA methylation patterns and gene expression in African American children with persistent atopic asthma (n = 36) versus healthy control subjects (n = 36). Results were validated in an independent population of asthmatic children (n = 30) by using a shared healthy control population (n = 36) and in an independent population of white adult atopic asthmatic patients (n = 12) and control subjects (n = 12).

RESULTS

We identified 186 genes with significant methylation changes, differentially methylated regions or differentially methylated probes, after adjustment for age, sex, race/ethnicity, batch effects, inflation, and multiple comparisons. Genes differentially methylated included those with established roles in asthma and atopy and genes related to extracellular matrix, immunity, cell adhesion, epigenetic regulation, and airflow obstruction. The methylation changes were substantial (median, 9.5%; range, 2.6% to 29.5%). Hypomethylated and hypermethylated genes were associated with increased and decreased gene expression, respectively (P < 2.8 × 10^-6 for differentially methylated regions and P < 7.8 × 10^-10 for differentially methylated probes). Quantitative analysis in 53 differentially expressed genes demonstrated that 32 (60%) have significant methylation-expression relationships within 5 kb of the gene. Ten loci selected based on the relevance to asthma, magnitude of methylation change, and methylation-expression relationships were validated in an independent cohort of children with atopic asthma. Sixty-seven of 186 genes also have significant asthma-associated methylation changes in nasal epithelia of adult white asthmatic patients.

CONCLUSIONS

Epigenetic marks in respiratory epithelia are associated with allergic asthma and gene expression changes in inner-city children.

Effect of aging on sputum inflammation and asthma control

BACKGROUND

Aged asthmatic patients experience increased morbidity and mortality. Knowledge of the aging effect on airway inflammation and asthma control is limited.

OBJECTIVE

We sought to compare airway inflammation and its relationship to asthma control in aged versus younger patients and determine whether differences are asthma specific or caused by "inflamm-aging."

METHODS

We performed a prospective study of aged (>60 years) and younger (21-40 years) inner-city patients with asthma. After a run-in period to control for inhaled corticosteroid use, induced sputum was collected. Age-matched nonasthmatic control subjects were included to measure age-related inflammatory changes.

RESULTS

Aged (mean age, 67.9 ± 5.1 years; n = 35) compared with younger (mean age, 30.8 ± 5.9 years; n = 37) asthmatic patients had significantly worse asthma control and lower FEV₁. Aged asthmatic patients had higher sputum neutrophil (30.5 × 10⁴/mL and 23.1%) and eosinophil (7.0 × 10⁴/mL and 3.8%) numbers and percentages compared with younger patients (neutrophils, 13.0 × 10⁴/mL [P < .01] and 6.9% [P < .01]; eosinophils, 2.0 × 10⁴/mL [P < .01] and 1.2% [P < .01]). Aged asthmatic patients had higher sputum IL-6 (P < .01) and IL-8 (P = .01) levels. No significant inflammatory differences between aged and younger control subjects were observed. In aged asthmatic patients increased sputum IL-6 and macrophage inflammatory protein 3α/CCL20 levels were significantly associated with decreased asthma control and increased sputum neutrophil numbers and IL-1β, IL-6, and macrophage inflammatory protein 3α/CCL20 levels were associated with hospitalization.

CONCLUSIONS

The inflammatory patterns of aged versus younger asthmatic patients are associated with increased sputum neutrophil and eosinophil values and cytokine levels related to neutrophil recruitment. Differences in airway inflammation can contribute to diminished asthma control in the aged. Further understanding of asthma pathophysiology in aged patients is needed to improve management of this vulnerable population.

DNA methylation and childhood asthma in the inner city

BACKGROUND

Epigenetic marks are heritable, influenced by the environment, direct the maturation of T lymphocytes, and in mice enhance the development of allergic airway disease. Thus it is important to define epigenetic alterations in asthmatic populations.

OBJECTIVE

We hypothesize that epigenetic alterations in circulating PBMCs are associated with allergic asthma.

METHODS

We compared DNA methylation patterns and gene expression in inner-city children with persistent atopic asthma versus healthy control subjects by using DNA and RNA from PBMCs. Results were validated in an independent population of asthmatic patients.

RESULTS

Comparing asthmatic patients (n = 97) with control subjects (n = 97), we identified 81 regions that were differentially methylated. Several immune genes were hypomethylated in asthma, including IL13, RUNX3, and specific genes relevant to T lymphocytes (TIGIT). Among asthmatic patients, 11 differentially methylated regions were associated with higher serum IgE concentrations, and 16 were associated with percent predicted FEV1. Hypomethylated and hypermethylated regions were associated with increased and decreased gene expression, respectively (P < 6 × 10(-12) for asthma and P < .01 for IgE). We further explored the relationship between DNA methylation and gene expression using an integrative analysis and identified additional candidates relevant to asthma (IL4 and ST2). Methylation marks involved in T-cell maturation (RUNX3), TH2 immunity (IL4), and oxidative stress (catalase) were validated in an independent asthmatic cohort of children living in the inner city.

CONCLUSIONS

Our results demonstrate that DNA methylation marks in specific gene loci are associated with asthma and suggest that epigenetic changes might play a role in establishing the immune phenotype associated with asthma.

Influence of early-life exposures on food sensitization and food allergy in an inner-city birth cohort

OBJECTIVE

Previous data suggest that food allergy (FA) might be more common in inner-city children; however, these studies have not collected data on both sensitization and clinical reactivity or early-life exposures.

METHODS

Children in the Urban Environment and Childhood Asthma birth cohort were followed through age 5 years. Household exposures, diet, clinical history, and physical examinations were assessed yearly; levels of specific IgE to milk, egg, and peanut were measured at 1, 2, 3, and 5 years of age. On the basis of sensitization (IgE ≥0.35 kU/L) and clinical history over the 5-year period, children were classified as having FA or being possibly allergic, sensitized but tolerant, or not allergic/not sensitized.

RESULTS

Five hundred sixteen children were included. Overall, 55.4% were sensitized (milk, 46.7%; egg, 31.0%; and peanut, 20.9%), whereas 9.9% were categorized as having FA (peanut, 6.0%; egg, 4.3%; and milk, 2.7%; 2.5% to >1 food). The remaining children were categorized as possibly allergic (17.0%), sensitized but tolerant (28.5%), and not sensitized (44.6%). Eighteen (3.5%) reported reactions to foods for which IgE levels were not measured. Food-specific IgE levels were similar in children with FA versus sensitized but tolerant children, except for egg, levels of which were higher in patients with FA at ages 1 and 2 years. FA was associated with recurrent wheeze, eczema, aeroallergen sensitization, male sex, breast-feeding, and lower endotoxin exposure in year 1 but not with race/ethnicity, income, tobacco exposure, maternal stress, or early introduction of solid foods.

CONCLUSIONS

Even given that this was designed to be a high-risk cohort, the cumulative incidence of FA is extremely high, especially considering the strict definition of FA that was applied and that only 3 common allergens were included.

Effects of early-life exposure to allergens and bacteria on recurrent wheeze and atopy in urban children

BACKGROUND

Wheezing illnesses cause major morbidity in infants and are frequent precursors to asthma.

OBJECTIVE

We sought to examine environmental factors associated with recurrent wheezing in inner-city environments.

METHODS

The Urban Environment and Childhood Asthma study examined a birth cohort at high risk for asthma (n = 560) in Baltimore, Boston, New York, and St Louis. Environmental assessments included allergen exposure and, in a nested case-control study of 104 children, the bacterial content of house dust collected in the first year of life. Associations were determined among environmental factors, aeroallergen sensitization, and recurrent wheezing at age 3 years.

RESULTS

Cumulative allergen exposure over the first 3 years was associated with allergic sensitization, and sensitization at age 3 years was related to recurrent wheeze. In contrast, first-year exposure to cockroach, mouse, and cat allergens was negatively associated with recurrent wheeze (odds ratio, 0.60, 0.65, and 0.75, respectively; P ≤ .01). Differences in house dust bacterial content in the first year, especially reduced exposure to specific Firmicutes and Bacteriodetes, was associated with atopy and atopic wheeze. Exposure to high levels of both allergens and this subset of bacteria in the first year of life was most common among children without atopy or wheeze.

CONCLUSIONS

In inner-city environments children with the highest exposure to specific allergens and bacteria during their first year were least likely to have recurrent wheeze and allergic sensitization. These findings suggest that concomitant exposure to high levels of certain allergens and bacteria in early life might be beneficial and suggest new preventive strategies for wheezing and allergic diseases.

Complementary and alternative medicine use by patients visiting a free health clinic: A single-site, pilot study

BACKGROUND

The rate of use of complementary and alternative medicine (CAM) has been documented to fluctuate widely, can greatly impact medical outcomes, and can influence patients' adherence to conventional medicines. Health care providers should assess the prevalence of CAM use (primarily herbal medicine) in individual settings to most accurately provide appropriate patient care.

OBJECTIVES

THE AIM OF THIS STUDY WAS TO DETERMINE THE FOLLOWING: (1) differences in demographic characteristics between users and nonusers of CAM; (2) which CAM patients are using; (3) patients' sources of information concerning CAM; and (4) whether patients recall being asked about CAM use by their health care providers.

METHODS

In this single-center, pilot study, a self-administered survey concerning CAM use was made available to persons seeking care at an inner-city free health clinic (Kansas City Free Health Clinic, Kansas City, Missouri). Completed surveys were scanned into a database, and descriptive analyses were performed.

RESULTS

Three hundred eleven patients completed ≥1 question on the survey. Of those who reported race (n = 278), 168 (60.4%) were Caucasian/white, 73 (26.3%) were African American/black, and 24 (8.6%) were Hispanic/Latino. Of those who reported educational level (n = 287), 101 (35.2%) had some high school or were high school graduates or had a general equivalency development diploma, 102 (35.5%) had completed some college or vocational training, and 84 (29.3%) had completed college. Of those who reported personal annual income (n = 191), 107 (56.0%) reported up to US $15,000, and 54 (28.3%) reported >$15,000 to $30,000. A high rate of CAM use (past or present) was found among survey respondents (116/285 [40.7%]). No correlation was found between CAM use and any of the demographic characteristics studied. Of 98 patients reporting whether their CAM use was past or current, 64 (65.3%) were using CAM at the time of the survey. Friends and physicians were reported to be most supportive of CAM use (21/41 [51.2%] and 33/86 [38.4%] patients, respectively). The most common CAM products reported as being currently used were garlic and chamomile (both, 5 patients [7.1%]), and echinacea and ginseng (both, 3 patients [4.7%]).

CONCLUSION

This survey of patients using an inner-city free health clinic showed a high rate of CAM use, which could significantly impact patient outcomes.

Challenges to traditional clinical definitions of depression in young black men

Despite high rates of unemployment, incarceration, violence, and suicide experienced by young Black men in America, research conducted in inner-city environments consistently report nonsignificant levels of depression among Black men. The unique history of social exclusion, stereotyping, and discrimination experienced by Black men has significant implications for the accurate assessment of depression. A review of significant historical and current sociological, educational, and legal-justice circumstances that affect the mental health of young Black men is presented. Barriers and limitations to traditional depression assessment and measurement is discussed and followed by recommendations for advancing knowledge of depression in young Black men. Research and practice that seeks to explore and explain sociocultural variances in traditional definitions of depression among young Black men will improve mental health, mental health outreach, and social function in this population.

Factors associated with completion of a behavioral intervention for caregivers of urban children with asthma

BACKGROUND

Rates of preventive follow-up asthma care after an acute emergency department (ED) visit are low among inner-city children. We implemented a novel behavioral asthma intervention, Pediatric Asthma Alert (PAAL) intervention, to improve outpatient follow-up and preventive care for urban children with a recent ED visit for asthma.

OBJECTIVE

The objective of this article is to describe the PAAL intervention and examine factors associated with intervention completers and noncompleters.

METHODS

Children with persistent asthma and recurrent ED visits (N = 300) were enrolled in a randomized controlled trial of the PAAL intervention that included two home visits and a facilitated follow-up visit with the child's primary care provider (PCP). Children were categorized as intervention completers, that is, completed home and PCP visits compared with noncompleters, who completed at least one home visit but did not complete the PCP visit. Using chi-square test of independence, analysis of variance, and multiple logistic regression, the intervention completion status was examined by several sociodemographic, health, and caregiver psychological variables.

RESULTS

Children were African-American (95%), Medicaid insured (91%), and young (aged 3-5 years, 56%). Overall, 71% of children randomized to the intervention successfully completed all home and PCP visits (completers). Factors significantly associated with completing the intervention included younger age (age 3-5 years: completers, 65.4%; noncompleters, 34.1%; p < .001) and having an asthma action plan in the home at baseline (completers: 40%; noncompleters: 21%; p = .02). In a logistic regression model, younger child age, having an asthma action plan, and lower caregiver daily asthma stress were significantly associated with successful completion of the intervention.

CONCLUSIONS

The majority of caregivers of high-risk children with asthma were successfully engaged in this home and PCP-based intervention. Caregivers of older children with asthma and those with high stress may need additional support for program completion. Further, the lack of an asthma action plan may be a marker of preexisting barriers to preventive care.

Allergens in urban schools and homes of children with asthma

BACKGROUND

Most studies of indoor allergens have focused on the home environment. However, schools may be an important site of allergen exposure for children with asthma. We compared school allergen exposure to home exposure in a cohort of children with asthma. Correlations between settled dust and airborne allergen levels in classrooms were examined.

METHODS

Settled dust and airborne samples from 12 inner-city schools were analyzed for indoor allergens using multiplex array technology (MARIA). School samples were linked to students with asthma enrolled in the School Inner-City Asthma Study (SICAS). Settled dust samples from students' bedrooms were analyzed similarly.

RESULTS

From schools, 229 settled dust and 197 airborne samples were obtained. From homes, 118 settled dust samples were obtained. Linear mixed regression models of log-transformed variables showed significantly higher settled dust levels of mouse, cat and dog allergens in schools than homes (545% higher for Mus m 1, estimated absolute difference 0.55 μg/g, p < 0.0001; 198% higher for Fel d 1, estimated absolute difference 0.13 μg/g, p = 0.0033; and 144% higher for Can f 1, estimated absolute difference 0.05 μg/g, p = 0.0008). Airborne and settled dust Mus m 1 levels in classrooms were moderately correlated (r = 0.48; p < 0.0001). There were undetectable to very low levels of cockroach and dust mite allergens in both homes and schools.

CONCLUSION

Mouse allergen levels in schools were substantial. In general, cat and dog allergen levels were low, but detectable, and were higher in schools. Aerosolization of mouse allergen in classrooms may be a significant exposure for students. Further studies are needed to evaluate the effect of indoor allergen exposure in schools on asthma morbidity in students with asthma.

Experiencing violence as a predictor of drug use relapse among former drug users in Baltimore, Maryland

The purpose of this study was to examine experiencing violence as a predictor of subsequent drug relapse among a sample of former crack, cocaine, and heroin users in Baltimore, MD, USA. The sample consists of 228 former drug users in Baltimore who were recruited through street outreach. Mixed-effects models were used to examine experiencing violence as a predictor of drug relapse at follow-up after adjusting for clustering of responses among participants living in the same census block. Using longitudinal data, we found that experiencing violence in the past year predicted drug relapse at 2-year follow-up among former drug users. Results indicate experiencing violence is a determinant of drug use relapse and highlight the importance of addressing the fundamental issues of violence experienced in inner-city communities. Addressing the extent of recent violence among drug treatment participants, providing coping skills, and reducing community violence are strategies that may address the link between violence and drug relapse.

Predictors of airborne endotoxin concentrations in inner city homes

Few studies have assessed in home factors which contribute to airborne endotoxin concentrations. In 85 inner city Baltimore homes, we found no significant correlation between settled dust and airborne endotoxin concentrations. Certain household activities and characteristics, including frequency of dusting, air conditioner use and type of flooring, explained 36-42% of the variability of airborne concentrations. Measurements of both airborne and settled dust endotoxin concentrations may be needed to fully characterize domestic exposure in epidemiologic investigations.

Prevalence of low bone mineral density in a low-income inner-city population

Bone mineral density (BMD) is an important factor linked to bone health. Little is known of the prevalence of low BMD and its associated risk factors in an urban underserved population. Between 2001 and 2004, we recruited 338 subjects who completed drug use and medical history questionnaires, underwent hormonal measurements, and underwent whole-body dual-energy X-ray absorptiometry (DXA) for evaluation of BMD and body composition. Of these, 132 subjects had site-specific DXA (lumbar spine and hip) performed. Osteoporosis was defined as a T-score of -2.5 or less for men 50 years of age and older and postmenopausal women and a Z-score of -2.0 or less in men younger than 50 years of age and premenopausal women at either the lumbar spine, total hip, or femoral neck, according to National Osteoporosis Foundation (NOF) guidelines. The cohort consisted of mostly African-American, middle-aged people with a high prevalence of illicit drug use, 50% HIV(+), and 39% hepatitis C(+). Osteoporosis was identified in 22% of subjects (24 men, 5 women), with the majority of cases (90%) attributable to osteoporosis at the lumbar spine. Osteoporosis was more common in men than in women. Lower whole-body BMD among women was associated with multiple risk factors, but only with lower lean mass among men. Osteoporosis was highly prevalent in men, mainly at the spine. The risk factors for bone loss in this population need to be further clarified. Screening men for osteoporosis starting at age 50 might be warranted in this population given the multiple risk factors and the unexpectedly high prevalence of low BMD.

Prenatal di(2-ethylhexyl)phthalate exposure and length of gestation among an inner-city cohort

OBJECTIVE

Our objective was to assess the relationship between di(2-ethylhexyl)phthalate (DEHP) exposure during pregnancy and gestational age at delivery among 311 African American or Dominican women from New York City.

METHODS

Forty-eight-hour personal air and/or spot urine samples were collected during the third trimester. DEHP levels were measured in air samples and 4 DEHP metabolite levels were measured in urine. Specific gravity was used to adjust for urinary dilution. Gestational age was abstracted from newborn medical records (n = 289) or calculated from the expected date of delivery (n = 42). Multivariate linear regression models controlled for potential confounders.

RESULTS

DEHP was detected in 100% of personal air samples (geometric mean: 0.20 microg/m(3) [95% confidence interval [CI]: 0.18-0.21 microg/m(3)]); natural logarithms of air concentrations were inversely but not significantly associated with gestational age. Two or more of the DEHP metabolites were detected in 100% of urine samples (geometric mean: 4.8-38.9 ng/mL [95% CI: 4.1-44.3 ng/mL]). Controlling for potential confounders, gestational age was shorter by 1.1 days (95% CI: 0.2-1.8 days) for each 1-logarithmic unit increase in specific gravity-adjusted mono(2-ethylhexyl)phthalate concentrations (P = .01) and averaged 5.0 days (95% CI: 2.1-8.0 days) less among subjects with the highest versus lowest quartile concentrations (P = .001). Results were similar and statistically significant for the other DEHP metabolites.

CONCLUSIONS

Prenatal DEHP exposure was associated with shorter gestation but, given inconsistencies with previous findings for other study populations, results should be interpreted with caution, and additional research is warranted.

Correlation between ERMI values and other moisture and mold assessments of homes in the American Healthy Homes Survey

The main objective of this study was to evaluate the correlation between the Environmental Relative Moldiness Index (ERMI) values in the Department of Housing and Urban Development American Healthy Homes Survey (AHHS) homes and an alternative analysis frequently used in mold investigations, i.e., the inspector's "walk-through" assessment of visual or olfactory evidence of mold combined with occupant's answers to a questionnaire about mold odors and moisture. Homes in the highest ERMI quartile were in agreement with visual inspection and/or occupant assessment 48% of the time but failed to detect the mold in 52% of the fourth quartile homes. In about 7% of lowest ERMI quartile homes, the inspection and occupant assessments overestimated the mold problem. The ERMI analysis of dust from homes may be useful in finding hidden mold problems. An additional objective was to compare the ERMI values in inner city east-Baltimore homes, where childhood asthma is common, to the AHHS randomly selected homes.

Does higher body mass index contribute to worse asthma control in an urban population?

BACKGROUND

Epidemiologic findings support a positive association between asthma and obesity.

OBJECTIVE

Determine whether obesity or increasing level of body mass index (BMI) are associated with worse asthma control in an ethnically diverse urban population.

METHODS

Cross-sectional assessment of asthma control was performed in patients with asthma recruited from primary care offices by using 4 different validated asthma control questionnaires: the Asthma Control and Communication Instrument (ACCI), the Asthma Control Test (ACT), the Asthma Control Questionnaire (ACQ), and the Asthma Therapy Assessment Questionnaire (ATAQ). Multiple linear regression analysis was performed to evaluate the association between obesity and increasing BMI level and asthma control.

RESULTS

Of 292 subjects with a mean age of 47 years, the majority were women (82%) and African American (67%). There was a high prevalence of obesity with 63%, with only 15% normal weight. The mean score from all 4 questionnaires showed an average suboptimal asthma control (mean score/maximum possible score): ACCI (8.3/19), ACT (15.4/25), ACQ (2.1/6), and ATAQ (1.3/4). Regression analysis showed no association between obesity or increasing BMI level and asthma control using all 4 questionnaires. This finding persisted even after adjusting for FEV(1), smoking status, race, sex, selected comorbid illnesses, and long-term asthma controller use.

CONCLUSION

Using 4 validated asthma control questionnaires, we failed to find an association between obesity and asthma control in an urban population with asthma. Weight loss may not be an appropriate strategy to improve asthma control in this population.

Changes in childhood immunization disparities between central cities and their respective states, 2000 versus 2006

Central cities have lower childhood immunization coverage rates than states in which they are located. We conducted a secondary analysis of the National Immunization Survey (NIS) 2000 and 2006 of children 19-35 months old for 26 NIS-defined central cities and the rest of their respective states in order to examine patterns in early childhood immunization disparities between central cities and their respective states and the contextual factors associated with these disparities. We examined three measures of immunization disparities (absolute, difference, and ratio of change) and the patterns of disparity change with regard to selected contextual factors derived from the census. In 2000, immunization coverage in central cities was 68.3% and 74.7% in the rest of their states, a 6.4% disparity (t = 3.82, p < 0.000). Between 2000 and 2006, the overall city/state disparity narrowed to 3.5%, with the central city coverage up to 78.7% vs. 82.5% for the rest of state (t = 2.48, p = 0.017). However, changes in immunization disparities were not uniform: six cities narrowed, 14 had minimal change, and six widened. Central cities with a larger share of Hispanics experienced less reduction in disparities than other cities (beta = -4.2, t = -2.11, p = 0.047). Despite overall progress in childhood immunization coverage, most central cities still show significant disparities with respect to the rest of their states. Cities with larger Hispanic populations may need extra help in narrowing their disparities.

HIV testing rates, testing locations, and healthcare utilization among urban African-American men

African-American men bear a disproportionate burden of HIV infection in the United States. HIV testing is essential to ensure that HIV-infected persons are aware of their HIV-positive serostatus, can benefit from early initiation of antiretroviral therapy, and can reduce their risk of transmitting the virus to sex partners. This cross-sectional study assessed HIV testing history and healthcare utilization among 352 young African-American men recruited in urban neighborhoods in a Midwestern city. The self-administered survey measured sexual risk behaviors, factors associated with HIV testing, and barriers to testing. The acceptability of community venues for HIV testing was also assessed. Of the respondents, 76% had been tested for HIV at some time in their lives, 52% during the prior 12 months. Of the participants, 70% had unprotected intercourse during the prior 12 months, 26% with two or more partners. Nearly three-quarters (72%) of participants had seen a healthcare provider during the prior year. In univariate analyses, those who had at least one healthcare provider visit during the prior 12 months and those who had a primary doctor were more likely to have been tested in the prior 12 months. In multivariate analyses, having a regular doctor who recommended HIV testing was the strongest predictor of having been tested [OR=7.38 (3.55, 15.34)]. Having been diagnosed or treated for a sexually transmitted disease also was associated with HIV testing [OR=1.83 (1.04, 3.21)]. The most commonly preferred testing locations were medical settings. However, community venues were acceptable alternatives. Having a primary doctor recommend testing was strongly associated with HIV testing and most HIV testing occurred at doctors' offices. But, a substantial proportion of persons were not tested for HIV, even if seen by a doctor. These results suggest that HIV testing could be increased within the healthcare system by increasing the number of recommendations made by physicians to patients. The use of community venues for HIV testing sites could further increase the number of persons tested for HIV.

A longitudinal study of indoor nitrogen dioxide levels and respiratory symptoms in inner-city children with asthma

BACKGROUND

The effect of indoor nitrogen dioxide concentrations on asthma morbidity among inner-city preschool children is uncertain.

OBJECTIVES

Our goal was to estimate the effect of indoor NO2 concentrations on asthma morbidity in an inner-city population while adjusting for other indoor pollutants.

METHODS

We recruited 150 children (2-6 years of age) with physician-diagnosed asthma from inner-city Baltimore, Maryland. Indoor air was monitored over a 72-hr period in the children's bedrooms at baseline and 3 and 6 months. At each visit, the child's caregiver completed a questionnaire assessing asthma symptoms over the previous 2 weeks and recent health care utilization.

RESULTS

Children were 58% male, 91% African American, and 42% from households with annual income < $25,000; 63% had persistent asthma symptoms. The mean (+/- SD) in-home NO2 concentration was 30.0 +/- 33.7 (range, 2.9-394.0) ppb. The presence of a gas stove and the use of a space heater or oven/stove for heat were independently associated with higher NO2 concentrations. Each 20-ppb increase in NO2 exposure was associated significantly with an increase in the number of days with limited speech [incidence rate ratio (IRR) = 1.15; 95% confidence interval (CI), 1.05-1.25], cough (IRR = 1.10; 95% CI, 1.02-1.18), and nocturnal symptoms (IRR = 1.09; 95% CI, 1.02-1.16), after adjustment for potential confounders. NO2 concentrations were not associated with increased health care utilization.

CONCLUSIONS

Higher indoor NO2 concentrations were associated with increased asthma symptoms in preschool inner-city children. Interventions aimed at lowering NO2 concentrations in inner-city homes may reduce asthma morbidity in this vulnerable population.

Identification and education of adolescents with asthma in an urban school district: results from a large-scale asthma intervention

Asthma is a leading cause of hospitalizations, acute care utilization, health care costs, and school absences in children. Asthma morbidity is disproportionately high in inner city populations. In general, community-based public health interventions to reduce asthma morbidity have had modest success due in part to their limited reach and low participation by the targeted population. Adolescents have been especially difficult to reach. A coalition of community organizations developed a school-based, population-level system to identify, prioritize, and provide interventions for middle school children with asthma in a large urban school district in Oakland, CA. Nearly 92% (n = 8,326) of students in the targeted schools took an asthma case identification survey. Of those students who took the survey, 17.5% (n = 1,458) had active asthma and were eligible for services. Among those identified with active asthma, 83% (n = 1,217) voluntarily attended asthma self-management classes at school. The 4-week curriculum previously has been shown to significantly improve several indicators of asthma control in this population. Retention was high-72% of students who enrolled attended at least three of the four curriculum sessions. Many higher-risk students were subsequently referred to and enrolled in off-site asthma services. Large school districts with incomplete or inadequate health records, high asthma prevalence, and internal or external services available for students with asthma may benefit from a similar model. A system such as the one described may be an effective public health strategy for school districts, health departments, and community coalitions addressing asthma or other conditions with high childhood prevalence.

Duality in context: the process of preparedness in communicating with at-risk children

The goal of this study was to explore the cultural meaning of parent-child communication behaviors in inner-city children at risk for common behavioral problems. Following participation in a preventive intervention called Insights Into Children's Temperament, 40 parents of first and second-grade children were interviewed. The data were analyzed using a constant comparative method derived from grounded-theory techniques. Findings indicate that a complex communication process was used by parents with their at-risk inner-city school-age children. The immediacy of safety concerns for the child, the child's temperament, and the current parental state informed the choice of communication behaviors chosen by the parent. The ultimate goal of communication for these participants was to equip their children with tools to assist them to safely navigate their school and community environments. Participants also offered several recommendations that could be useful for practitioners and researchers to incorporate into their work with inner-city families.

Self-reported moisture or mildew in the homes of Head Start children with asthma is associated with greater asthma morbidity

This study used results from a cross-sectional survey of parents of 3- to 5-year-old children with asthma to assess the frequency of self-reported home environmental conditions that could contribute to worsening asthma and examined the relationship between these factors and the child's asthma morbidity. Participants were 149 parents drawn from the two largest agencies that provide subsidized preschool childcare services in East and Central Harlem, inner-city communities with high prevalence of asthma. The sample represented 77% of eligibles determined by a validated case-identification instrument. Data were collected on demographics, symptoms, medication use, Emergency Department visits and hospitalization, and environmental conditions in the home. One or more of these home environmental conditions were reported by 92% of participants. Controlling for other environmental conditions and demographics, associations were found between self-reported presence of moisture or mildew on ceilings, walls, or windows and higher frequency of hospitalizations for breathing-related problems (OR = 3.31; 95% CI 1.62-6.75), frequent episodes of wheezing (OR = 3.25; 95% CI 1.8-6.0), and higher frequency of night symptoms due to asthma (OR = 2.19; 95% CI 1.4-3.41). Having a carpet or rug in the child's bedroom or the living room was also associated with hospitalizations (OR = 3.23; 95% CI 1.53-6.8), and male gender was marginally associated with the frequency of night symptoms (OR = 1.51; 95% CI .95-2.4). Asthma is prevalent in the Head Start population, and exposure to home environmental conditions that may worsen asthma is common in the socially disadvantaged populations served by Head Start programs.

An evaluation of the effects of INSIGHTS on the behavior of inner city primary school children

A prevention trial was conducted to evaluate a temperament-based intervention (INSIGHTS into Children's Temperament) as compared to a Read Aloud attention control condition in reducing behavior problems among inner city children. The participants were 148 inner-city first and second grade children, their parents, and their 46 teachers who were from six schools in a Northeastern city. Parents were interviewed on the Parent Daily Report at baseline and every two weeks until the completion of the intervention phase to assess the extent of child problem behaviors in the home. The parents also were interviewed at baseline with the Disruptive Module of the Diagnostic Interview for Children and completed the Brief Symptom Index to assess parental depression.A repeated measures multivariate analysis of covariance with parental depression as a covariate was conducted to examine the children's behavior over the course of the intervention. In order to test the impact of INSIGHTS for the overall sample and to determine whether the intervention was differentially effective for children diagnosed with a disruptive disorder versus those who did not receive a diagnosis, two and three-way interactions were examined and found to be significant. The INSIGHTS intervention was more effective than Read Aloud in reducing children's problem behaviors at home across both the diagnosed and non-diagnosed groups, but demonstrated a significantly greater efficacy among children who were at diagnostic levels compared to those who were within normal levels. Editors' Strategic Implications: The authors describe the promising practice of instructing parents and teachers on how to adapt their behavior management strategies to fit each child's temperament. Replication with a longitudinal follow-up will be necessary to determine whether program effects persist.

Addressing the unique challenges of inner-city practice: a direct observation study of inner-city, rural, and suburban family practices

Previous research on geographic variations in health care contains limited information regarding inner-city medical practice compared with suburban and rural settings. Our main objective was to compare patient characteristics and the process of providing medical care among family practices in inner-city, suburban, and rural locations. A cross-sectional multimethod study was conducted emphasizing direct observation of outpatient visits by trained research nurses involving 4,454 consecutive patients presenting for outpatient care to 138 family physicians during 2 days of observation at 84 community family practices in northeast Ohio. Time use during office visits was assessed with the Davis Observation Code; satisfaction was measured with the Medical Outcomes Study nine-item Visit Rating Scale; delivery of preventive services was as recommended by the US Preventive Services Task Force; and patient-reported domains of primary care were assessed with the Components of Primary Care Instrument. Results show that inner-city patients had more chronic medical problems, more emotional problems, more problems evaluated per visit, higher rates of health habit counseling, and longer and more frequent office visits. Rural patients were older, more likely to be established with the same physician, and had higher rates of satisfaction and patient-reported physician knowledge of the patient. Suburban patients were younger, had fewer chronic medical problems, and took fewer medications chronically. Inner-city family physicians in northeast Ohio appear to see a more challenging patient population than their rural and suburban counterparts and have more complex outpatient office visits. These findings have implications for health system organization along with the reimbursement and recruitment of physicians in medically underserved inner-city areas.

Knowledge of Home Dialysis Among Inner-City Satellite Hemodialysis Patients

There is limited use of home renal replacement therapies in the U.S.A. One percent of dialysis patients are on home hemodialysis (HHD) and only 9% undergo peritoneal dialysis (PD). In an effort to better understand this, 161 satellite hemodialysis patients in 6 units in Brooklyn were surveyed. Forty-eight percent of patients were women, 86% were black, 5% white, 8% Hispanic, and 1% other. Mean age was 49.4 years (range 22 - 69 years). Etiology of renal disease was hypertension (41%), diabetes mellitus (31%), polycystic kidney disease (3%), systemic lupus erythematosus (4%), and other or unknown (21%). Patients were queried about knowledge of and attitudes toward home therapies. Seventy-nine percent of patients knew of home dialysis. The source of this information was the nephrologist (59%), the social worker (14%), a nurse (8%), other patients (4%), and other sources (15%). Only 10% of patients had ever considered HHD. Fifty-four percent were afraid to do self-care at home and 35% were not interested. Surprisingly, only 3% felt they had no reliable helper and 8% felt that their housing was not suitable. Similarly, 78% of patients had been spoken to about PD, but only 11% had considered it. Forty-one percent were afraid of doing self-care on PD, and 45% were not interested. We conclude that, although the majority of patients in six inner-city dialysis units had heard of home dialysis, only a small number ever considered it. As many patients were afraid of doing home therapy, better education about the risks and benefits needs to be disseminated.
