Relative Vaccine Effectiveness of Cell- vs Egg-Based Quadrivalent Influenza Vaccine Against Test-Confirmed Influenza Over 3 Seasons Between 2017 and 2020 in the United States.

Background: Influenza vaccine viruses grown in eggs may acquire egg-adaptive mutations that may reduce antigenic similarity between vaccine and circulating influenza viruses and decrease vaccine effectiveness. We compared cell- and egg-based quadrivalent influenza vaccines (QIVc and QIVe, respectively) for preventing test-confirmed influenza over 3 US influenza seasons (2017-2020). Methods: Using a retrospective test-negative design, we estimated the relative vaccine effectiveness (rVE) of QIVc vs QIVe among individuals aged 4 to 64 years who had an acute respiratory or febrile illness and were tested for influenza in routine outpatient care. Exposure, outcome, and covariate data were obtained from electronic health records linked to pharmacy and medical claims. Season-specific rVE was estimated by comparing the odds of testing positive for influenza among QIVc vs QIVe recipients. Models were adjusted for age, sex, geographic region, influenza test date, and additional unbalanced covariates. A doubly robust approach was used combining inverse probability of treatment weights with multivariable regression. Results: The study included 31 824, 33 388, and 34 398 patients in the 2017-2018, 2018-2019, and 2019-2020 seasons, respectively; ∼10% received QIVc and ∼90% received QIVe. QIVc demonstrated superior effectiveness vs QIVe in prevention of test-confirmed influenza: rVEs were 14.8% (95% CI, 7.0%-22.0%) in 2017-2018, 12.5% (95% CI, 4.7%-19.6%) in 2018-2019, and 10.0% (95% CI, 2.7%-16.7%) in 2019-2020. Conclusions: This study demonstrated consistently superior effectiveness of QIVc vs QIVe in preventing test-confirmed influenza over 3 seasons characterized by different circulating viruses and degrees of egg adaptation.

Follow-up Post-discharge and Readmission Disparities Among Medicare Fee-for-Service Beneficiaries, 2018.

BACKGROUND: Previous studies have identified disparities in readmissions among Medicare beneficiaries hospitalized for the Hospital Readmissions Reduction Program's (HRRP's) priority conditions. Evidence suggests timely follow-up is associated with reduced risk of readmission, but it is unknown whether timely follow-up reduces disparities in readmission. OBJECTIVE: To assess whether follow-up within 7 days after discharge from a hospitalization reduces risk of readmission and mitigates identified readmission disparities. DESIGN: A retrospective cohort study using Cox proportional hazards models to estimate the associations between sociodemographic characteristics (race and ethnicity, dual-eligibility status, rurality, and area social deprivation), follow-up, and readmission. Mediation analysis was used to examine if disparities in readmission were mitigated by follow-up. PARTICIPANTS: We analyzed data from 749,402 Medicare fee-for-service beneficiaries hospitalized for acute myocardial infarction, chronic obstructive pulmonary disease, heart failure, or pneumonia, and discharged home between January 1 and December 1, 2018. MAIN MEASURE: All-cause unplanned readmission within 30 days after discharge. KEY RESULTS: Post-discharge follow-up within 7 days of discharge was associated with a substantially lower risk of readmission (HR: 0.52, 95% CI: 0.52-0.53). Across all four HRRP conditions, beneficiaries with dual eligibility and beneficiaries living in areas with high social deprivation had a higher risk of readmission. Non-Hispanic Black beneficiaries had higher risk of readmission after hospitalization for pneumonia relative to non-Hispanic Whites. Mediation analysis suggested that 7-day follow-up mediated 21.2% of the disparity in the risk of readmission between dually and non-dually eligible beneficiaries and 50.7% of the disparity in the risk of readmission between beneficiaries living in areas with the highest and lowest social deprivation. Analysis suggested that after hospitalization for pneumonia, 7-day follow-up mediated nearly all (97.5%) of the increased risk of readmission between non-Hispanic Black and non-Hispanic White beneficiaries. CONCLUSIONS: Improving rates of follow-up could be a strategy to reduce readmissions for all beneficiaries and reduce disparities in readmission based on sociodemographic characteristics.

Urbanization and health: The effects of the built environment on chronic disease risk factors among women in Tanzania.

Sub-Saharan Africa is experiencing rapid urban growth. Cities enable greater access to health services and improved water and sanitation infrastructure, leading to some improvements in health. However, urban settings may also be associated with more sedentary, stressful lifestyles and consumption of less nutritious food. C-reactive protein (CRP) is a measure of chronic inflammation predictive of cardiovascular disease, and high body mass index (BMI), a ratio of weight to height, indicates overweight or obesity and is associated with an increased risk of many chronic diseases. To explore the association between urbanicity and these two markers, we overlaid data from the 2010 Tanzania Demographic and Health Survey (DHS) with a satellite-derived measure of built environment. Linear regression models were constructed for the outcomes of BMI and CRP, by 1) administratively defined urban/rural categorization from the DHS, 2) satellite derived built environment, and 3) built environment stratified by urban/rural. A total of 2,212 women were included; 23% had elevated CRP, 21% were overweight or obese. A third (33%) lived in a highly built up area and 29% lived in an area classified as urban. A strong positive association between both CRP and BMI and built environment was detected; log CRP increased 0.43 in the highest built up areas compared to not built up (p<0.05); log BMI increased 0.02 in the most built up areas compared to not built up (p<0.05). However, comparing urban to rural category was only significant in unadjusted models. Models stratified by urban/rural category highlight that the variation in CRP and BMI by built environment is mainly driven by rural areas; within urban areas there is less variation. Our findings highlight the potential negative effects of urbanicity on chronic disease markers, with potentially more change detected for those transitioning from rural to urban lifestyles. Satellite-derived urbanicity measures are reproducible and provide more nuanced understanding of effects of built environment on health.

Evaluation of a health information exchange system for microcephaly case-finding - New York City, 2013-2015.

BACKGROUND: Birth defects surveillance in the United States is conducted principally by review of routine but lagged reporting to statewide congenital malformations registries of diagnoses by hospitals or other health care providers, a process that is not designed to rapidly detect changes in prevalence. Health information exchange (HIE) systems are well suited for rapid surveillance, but information is limited about their effectiveness at detecting birth defects. We evaluated HIE data to detect microcephaly diagnosed at birth during January 1, 2013-December 31, 2015 before known introduction of Zika virus in North America. METHODS: Data from an HIE system were queried for microcephaly diagnostic codes on day of birth or during the first two days after birth at three Bronx hospitals for births to New York City resident mothers. Suspected cases identified by HIE data were compared with microcephaly cases that had been identified through direct inquiry of hospital records and confirmed by chart abstraction in a previous study of the same cohort. RESULTS: Of 16,910 live births, 43 suspected microcephaly cases were identified through an HIE system compared to 67 confirmed cases that had been identified as part of the prior study. A total of 39 confirmed cases were found by both studies (sensitivity = 58.21%, 95% CI: 45.52-70.15%; positive predictive value = 90.70%, 95% CI: 77.86-97.41%; negative predictive value = 99.83%, 95% CI: 99.76-99.89% for HIE data). CONCLUSION: Despite limitations, HIE systems could be used for rapid newborn microcephaly surveillance, especially in the many jurisdictions where more labor-intensive approaches are not feasible. Future work is needed to improve electronic medical record documentation quality to improve sensitivity and reduce misclassification.

Use of Small-Area Estimates to Describe County-Level Geographic Variation in Prevalence of Extreme Obesity Among US Adults.

Importance: The prevalence of extreme obesity continues to increase among adults in the US, yet there is an absence of subnational estimates and geographic description of extreme obesity. This shortcoming prevents a thorough understanding of the geographic distribution of extreme obesity, which in turn limits the ability of public health agencies and policy makers to target areas with a known higher prevalence. Objectives: To use small-area estimation to create county-level estimates of extreme obesity in the US and apply spatial methods to identify clusters of high and low prevalence. Design, Setting, and Participants: A cross-sectional analysis was conducted using multilevel regression and poststratification with data from the 2012 Behavioral Risk Factor Surveillance System and the US Census Bureau to create prevalence estimates of county-level extreme obesity (body mass index ≥40 [calculated as weight in kilograms divided by height in meters squared]). Data were included on adults (aged ≥18 years) living in the contiguous US. Analysis was performed from June 4 to December 28, 2018. Main Outcomes and Measures: Multilevel logistic regression models estimated the probability of extreme obesity based on individual-level and area-level characteristics. Census counts were multiplied by these probabilities and summed by county to create county-level prevalence estimates. Moran index values were calculated to assess spatial autocorrelation and identify spatial clusters of hot and cold spots. Estimates of moderate obesity were obtained for comparison. Results: Overall, the weighted prevalence of extreme obesity was 4.0% (95% CI, 3.9%-4.1%) and the prevalence of moderate obesity was 23.7% (95% CI, 23.4%-23.9%). County-level prevalence of extreme obesity ranged from 1.3% (95% CI, 1.3%-1.3%) to 15.7% (95% CI, 15.3%-16.0%). The Pearson correlation coefficient comparing model-predicted estimates with direct estimates was 0.81 (P < .001). The Moran index I score was 0.35 (P < .001), indicating spatial clustering. Significant clusters of high and low prevalence were identified. Hot spots indicating clustering of high prevalence of extreme obesity in several regions, including the Mississippi Delta region and the Southeast, were identified, as well as clusters of low prevalence in the Rocky Mountain region and the Northeast. Conclusions and Relevance: Substantial geographic variation was identified in the prevalence of extreme obesity; there was considerable county-level variation even in states generally known as having high or low prevalence of obesity. The results suggest that extreme obesity prevalence demonstrates spatial dependence and clustering and may support the need for substate analysis and benefit of disaggregation of obesity by group. Findings from this study can inform local and national policies seeking to identify populations most at risk from very high body mass index.

Influence of prenatal maternal stress on umbilical cord blood cytokine levels.

PURPOSE: Prenatal maternal stress (PNMS) is known to influence fetal programming and development. Thus far, the effects of PNMS on the developing immune system have mainly been documented in animal studies. This study aimed to examine the association between PNMS and immune cytokine profiles in the umbilical cord blood of newborn human infants. METHODS: PNMS, including perceived stress, numbers of stressful life events experiences (both partner and health related), and state and trait anxiety, was assessed with five questionnaires and interviews from 43 pregnant women during the second trimester. Seven key cytokines important for immune function, i.e., IL-12, IL-1ß, IL-4, IL-5, IL-6, IL-8, and TNF-α, were analyzed in cord blood by bead-based ELISA method (Luminex 200). Logistic regression was used to estimate the associations of PNMS scores and cytokine levels. RESULTS: Increased levels of IL-1ß, IL-4, IL-5, IL-6, and IL-8 were significantly associated with at least one of the maternal stress assessments, while the levels of IL-12 and TNF-α were not significantly associated with any of the PNMS measurements examined. CONCLUSION: These preliminary findings suggest that PNMS may influence cytokine levels in newborn infants, in particular Th2-related cytokines. This report supports previous findings in animal studies and could suggest that newborns born to mothers with elevated PNMS have a predisposition to immune-related disorders.

A Pilot Study of a Family-Focused Intervention for Children and Families Affected by Maternal Depression.

A non-experimental pilot study examined child, mother, and family outcomes of a 10-session multi-family group intervention designed to reduce risk and promote resilience for mothers with depression and their families. Positive changes following the Keeping Families Strong intervention included mother-reported decreases in child behavior and emotional problems, improvements in the quality of family interactions and routines, and improvements in their own well being and support from others. Children (9-16 years) reported decreased internalizing symptoms, improved coping, increased maternal warmth and acceptance, and decreased stressful family events. Attendance and mother-reported satisfaction were high, indicating the perceived value of the intervention.

Development of a family-based program to reduce risk and promote resilience among families affected by maternal depression: theoretical basis and program description.

Depression is a family matter. It not only diminishes the quality-of-life of the depressed person, but also strains the resources of the family unit and increases the children's risk of developing significant problems that start early and persist into adulthood. Although treatment of a parent's depression is critical, many families also need professional intervention to reduce children's risk. This article reviews the evidence on needs of these families and shows that the theoretical and clinical evidence exists to support the design of interventions for families affected by maternal depression. A preventive intervention developed from this foundation is described, the Keeping Families Strong (KFS) program, that is designed to promote resilience and reduce the risk for psychological disorders in children of parents with depression. The pilot study on the KFS program, conducted in adult mental health outpatient settings, is described. Families participate in 10 meetings 90 min each, with a group for parents and for children (10 years and older) conducted concurrently. The program structure and content are described, the challenges of implementing a family preventive intervention in actual clinical settings are discussed, and a case example is provided, as well as preliminary outcome data on ten families. In sum, we provide a strong rationale for the potential of preventive interventions for families affected by maternal depression.

Transformation of children's mental health services: the role of school mental health.

The New Freedom Commission has called for a transformation in the delivery of mental health services in this country. The commission's report and recommendations have highlighted the role of school mental health services in transforming mental health care for children and adolescents. This article examines the intersection of school mental health programs and the commission's recommendations in order to highlight the role of school mental health in the transformation of the child and adolescent mental health system. Schools are uniquely positioned to play a central role in improving access to child mental health services and in supporting mental health and wellness as well as academic functioning of youths. The New Freedom Commission report articulated several goals related to school mental health: reducing stigma, preventing suicide, improving screening and treating co-occurring disorders, and expanding school mental health programs. The authors suggest strategies for change, including demonstrating relevance to schools, developing consensus among stakeholders, enhancing community mental health-school connections, building quality assessment and improvement, and considering the organizational context of schools.

The President's New Freedom Commission: capitalizing on opportunities to advance school-based mental health services.

The report from President George W. Bush's New Freedom Commission on Mental Health (NFC), Achieving the Promise: Transforming Mental Health Care in America(2003), proposes goals and recommendations for improving mental health services. This report has significant implications for the delivery of mental health services through the schools. A focused discussion of the potential opportunities and challenges of implementing NFC recommendations related to school-based mental health is presented. Strategies for addressing five key areas at the intersection of school mental health and the Commission's recommendations include: stigma reduction, suicide prevention, expansion and improvement of school mental health, and screening and treatment of co-occurring mental health and substance abuse disorders.

Enhancing No Child Left Behind-School mental health connections.

The No Child Left Behind Act of 2001 was signed into law by President George W. Bush in January 2002 and is regarded as the most significant federal education policy initiative in a generation. The primary focus of the No Child Left Behind Act is on promoting educational success for all children; however, the legislation also contains opportunities to advance school-based mental health. Unfortunately, the complexities of the provisions of the No Child Left Behind Act have made it difficult for educators, stakeholders, and mental health professionals to understand the legal and practical interface between No Child Left Behind and the school mental health movement. Therefore, the goals of this article are to (1) raise awareness about the challenges educators and school mental health professionals face as a result of the implementation of No Child Left Behind and (2) provide ideas and recommendations to advance the interface between No Child Left Behind and school mental health, which will support key provisions of the act and the growth of the field.

Use of narrative-based language intervention with children who have specific language impairment.

Ten 7-8-year-old children with specific language impairment participated in a 6-week program of narrative-based language intervention (NBLI) in an effort to evaluate NBLI's feasibility. Each intervention session targeted story content as well as story and sentence form using story retell and generation tasks. Eight children achieved the clinically significant improvement criterion from pre- and posttest comparisons of at least 1.45 points on a narrative quality (NQ) rating (p<.013). Throughout the NBLI program, the children were informally observed to show increased self-confidence in their narrative production skills. Nearly all children preferred story generation activities over story retell tasks, while story retell tasks were favored over sentence imitation drills. Pre- and posttest comparisons for number of different words, developmental sentence score, and a sentence imitation task were nonsignificant. This indicated no further evidence of positive outcomes for NBLI. Based on the significant findings for NQ, NBLI is worthy of further investigation. Modifications to enhance its ability to produce positive gains are discussed.
