Axion Wind Detection with the Homogeneous Precession Domain of Superfluid Helium-3.

Axions and axionlike particles may couple to nuclear spins like a weak oscillating effective magnetic field, the "axion wind." Existing proposals for detecting the axion wind sourced by dark matter exploit analogies to nuclear magnetic resonance (NMR) and aim to detect the small transverse field generated when the axion wind resonantly tips the precessing spins in a polarized sample of material. We describe a new proposal using the homogeneous precession domain of superfluid ^{3}He as the detection medium, where the effect of the axion wind is a small shift in the precession frequency of a large-amplitude NMR signal. We argue that this setup can provide broadband detection of multiple axion masses simultaneously and has competitive sensitivity to other axion wind experiments such as CASPEr-Wind at masses below 10^{-7} eV by exploiting precision frequency metrology in the readout stage.

Multistate Infestation with the Exotic Disease-Vector Tick Haemaphysalis longicornis - United States, August 2017-September 2018.

Haemaphysalis longicornis is a tick indigenous to eastern Asia and an important vector of human and animal disease agents, resulting in such outcomes as human hemorrhagic fever and reduction of production in dairy cattle by 25%. H. longicornis was discovered on a sheep in New Jersey in August 2017 (1). This was the first detection in the United States outside of quarantine. In the spring of 2018, the tick was again detected at the index site, and later, in other counties in New Jersey, in seven other states in the eastern United States, and in Arkansas. The hosts included six species of domestic animals, six species of wildlife, and humans. To forestall adverse consequences in humans, pets, livestock, and wildlife, several critical actions are indicated, including expanded surveillance to determine the evolving distribution of H. longicornis, detection of pathogens that H. longicornis currently harbors, determination of the capacity of H. longicornis to serve as a vector for a range of potential pathogens, and evaluation of effective agents and methods for the control of H. longicornis.

Efficacy of a lead based paint XRF analyzer and a commercially available colorimetric lead test kit as qualitative field tools for determining presence of lead in religious powders.

The performances of a portable X-Ray Fluorescence (XRF) lead paint analyzer (RMD LPA-1, Protec Instrument Corp., Waltham, MA) and a commercially available colorimetric lead test kit (First Alert Lead Test Kit, eAccess Solutions, Inc., Palatine, IL) were evaluated for use by local or state health departments as potential cost-effective rapid analysis or "spot test" field techniques for tentative identification of lead content in sindoor powders. For both field-sampling methods, sensitivity, specificity and predictive values varied widely for samples containing <300,000 µg/g lead. For samples containing ≥300,000 µg/g lead, the aforementioned metrics were 100% (however, the CIs had a wide range). In addition, both field sampling methods showed clear, consistent positive readings only for samples containing ≥300,000 µg/g lead. Even samples with lead content as high as 5,110 µg/g were not positively identified by either field analysis technique. The results of this study suggest the XRF analyzer and colorimetric lead test kit cannot be used as a rapid field test for sindoor by health department inspectors.

Lead Content of Sindoor, a Hindu Religious Powder and Cosmetic: New Jersey and India, 2014-2015.

OBJECTIVES: To assess the extent of lead content of sindoor, a powder used by Hindus for religious and cultural purposes, which has been linked to childhood lead poisoning when inadvertently ingested. METHODS: We purchased 95 samples of sindoor from 66 South Asian stores in New Jersey and 23 samples from India and analyzed samples with atomic absorption spectrophotometry methods for lead. RESULTS: Analysis determined that 79 (83.2%) sindoor samples purchased in the United States and 18 (78.3%) samples purchased in India contained 1.0 or more micrograms of lead per gram of powder. For US samples, geometric mean concentration was 5.4 micrograms per gram compared with 28.1 micrograms per gram for India samples. The maximum lead content detected in both US and India samples was more than 300 000 micrograms per gram. Of the examined US sindoor samples, 19% contained more than 20 micrograms per gram of lead (US Food and Drug Administration [FDA] limit); 43% of the India samples exceeded this limit. CONCLUSIONS: Results suggested continued need for lead monitoring in sindoor in the United States and in sindoor carried into the United States by travelers from India, despite FDA warnings.

Prevalence and Disparities in the Detection of Autism Without Intellectual Disability.

BACKGROUND: Intellectual ability predicts functional outcomes for children with autism spectrum disorder (ASD). It is essential to classify ASD children with and without intellectual disability (ID) to aid etiological research, provide services, and inform evidence-based educational and health planning. METHODS: Using a cross-sectional study design, data from 2000 to 2016 active ASD surveillance among 8-year-olds residing in the New York-New Jersey Metropolitan Area were analyzed to determine ASD prevalence with and without ID. Multivariable Poisson regression models were used to identify trends for ASD with ID (ASD-I) and without ID (ASD-N). RESULTS: Overall, 4661 8-year-olds were identified with ASD. Those that were ASI-I were 1505 (32.3%) and 2764 (59.3%) were ASD-N. Males were 3794 (81.4%), 946 (20.3%) were non-Hispanic Black (Black), 1230 (26.4%) were Hispanic, and 2114 (45.4%) were non-Hispanic white (white). We observed 2-fold and 5-fold increases in the prevalence of ASD-I and ASD-N, respectively, from 2000-2016. Black children were 30% less likely to be identified with ASD-N compared with white children. Children residing in affluent areas were 80% more likely to be identified with ASD-N compared with children in underserved areas. A greater proportion of children with ASD-I resided in vulnerable areas compared with children with ASD-N. Males had higher prevalence compared with females regardless of ID status; however, male-to-female ratios were slightly lower among ASD-I compared with ASD-N cases. CONCLUSIONS: One-in-3 children with ASD had ID. Disparities in the identification of ASD without ID were observed among Black and Hispanic children as well as among children residing in underserved areas.

Prevalence of autism spectrum disorder in a large, diverse metropolitan area: Variation by sociodemographic factors.

Autism spectrum disorder (ASD) prevalence estimates have varied by region. In this study, ASD prevalence, based on active case finding from multiple sources, was determined at the county and school district levels in the New Jersey metropolitan area. Among children born in 2008, residing in a four-county area and enrolled in public school in 2016, ASD prevalence was estimated to be 36 per 1000, but was significantly higher in one region-54 per 1000 and greater than 70 per 1000, in multiple school districts. Significant variation in ASD prevalence by race/ethnicity, socioeconomic status (SES), and school district size was identified. Highest prevalence was in mid-SES communities, contrary to expectation. Prevalence among Hispanic children was lower than expected, indicating a disparity in identification. Comprehensive surveillance should provide estimates at the county and town levels to appreciate ASD trends, identify disparities in detection or treatment, and explore factors influencing change in prevalence. LAY SUMMARY: We found autism prevalence to be 3.6% in New Jersey overall, but higher in one region (5.4%) and in multiple areas approaching 7.0%. We identified significant variation in autism spectrum disorder (ASD) prevalence by race/ethnicity, socioeconomic status (SES) and school district size. Mapping prevalence in smaller, well-specified, regions may be useful to better understand the true scope of ASD, disparities in ASD detection and the factors impacting ASD prevalence estimation.

Disparities in Early Intervention Program Participation by Children With Autism Spectrum Disorder in a US Metropolitan Area, 2006 to 2016.

Importance: Multiple studies have shown the value of early interventions for autism spectrum disorder (ASD). In the US, the Early Intervention Program (EIP) is mandated by law (Part C of the Individuals With Disabilities Education Act [IDEA]) to provide services to all young children with delays or disabilities. However, the extent to which children with ASD participate in this key service system is unknown. Objectives: To evaluate EIP use by children with ASD from 2006 to 2016 and to describe the factors associated with EIP participation. Design, Setting, and Participants: This cross-sectional study used repeated data collected from 2006 to 2016 by active ASD surveillance of the New York-New Jersey metropolitan area as reported in the New Jersey Autism Study. The New Jersey Autism Study identified 4050 children aged 8 years with ASD from 2006 to 2016. Demographic and clinical data were collected and participation in an EIP was assessed through active surveillance. Data were analyzed from June to December 2021. Exposure: Sociodemographic factors associated with the outcome of EIP participation. Main Outcomes and Measures: Participation in an EIP assessed at age 8 years. Demographic, ecological, and clinical factors, as well as temporal patterns, were examined by using standard and multilevel logistic regression models. Results: Among 4050 children aged 8 years with ASD by active surveillance, 1887 (46.6%) received EIP services. Of these children, 3303 (81.6%) were boys; 1105 (27.3%) were Hispanic, 801 (19.8%) were non-Hispanic Black, 1816 (44.8%) were non-Hispanic White, and 328 (8.1%) were non-Hispanic other (included Alaska Native or American Indian and Asian or Pacific Islander). In adjusted regression models, non-Hispanic Black children with ASD had lower odds of EIP participation (adjusted odds ratio [AOR], 0.67; 95% CI, 0.54-0.84) compared with their non-Hispanic White peers, and children residing in affluent areas had higher odds of receiving EIP services (AOR, 1.71; 95% CI, 1.36-2.15) compared with children residing in underserved areas. Children with ASD born in 2008 had higher odds of EIP participation than children born in 1998 (AOR, 2.64; 95% CI, 2.07-3.36). Conclusions and Relevance: Early identification of ASD is an important public health priority and receipt of EIP services may improve ASD outcomes. Approximately half of the population of children aged 8 years with ASD received EIP services between 2006 and 2016, and EIP participation by children with ASD increased during the 10-year period. However, receipt of EIP services was marked by strong socioeconomic status- and race and ethnicity-based disparities. Universal ASD screening and additional strategies are needed to address disparities and to increase access to EIP services.

Prevalence and trend in the use of hospital-based standing orders programs for influenza and pneumococcal vaccination.

BACKGROUND: In 2002, federal regulations authorized the use of standing orders programs (SOPs) for promoting influenza and pneumococcal vaccination. In 2003, the New Jersey Hospital Association conducted a demonstration project illustrating the efficacy of SOPs, and the state health department informed healthcare facilities of their benefits. We describe the prevalence of reported use of SOPs in New Jersey hospitals in 2003 and 2005 and identify hospital characteristics associated with the use of SOPs. METHODS: A survey was mailed to the directors of infection control at 117 New Jersey hospitals during the period from January to May 2005 (response rate, 90.6%). Data on hospital characteristics were obtained from hospital directories and online resources. RESULTS: The prevalence of use of SOPs for influenza vaccination was 50% (95% confidence interval [CI], 40.1%-59.9%) in 2003, and it increased to 78.3% (95% CI, 69.2%-85.7%) in 2005. The prevalence of SOP use for pneumococcal vaccination was similar. In 2005, the reported rate of use of SOPs for inpatients (influenza vaccination, 76.4%; pneumococcal vaccination, 75.5%) was significantly higher than that for outpatients (influenza vaccination, 9.4%; pneumococcal vaccination, 8.5%). Prevalence ratios for SOP use comparing acute care and non-acute care hospitals were 1.71 (95% CI, 1.2-2.5) for influenza vaccination SOPs and 1.8 for (95% CI, 1.2-2.7) pneumococcal vaccination SOPs. Acute care hospitals with a ratio of admissions to total beds greater than 36.7 reported greater use of SOPs for pneumococcal vaccination, compared with those that had a ratio of less than 36.7. CONCLUSION: The increase in the prevalence of reported use of SOPs among New Jersey hospitals in 2005, compared with 2003, was contemporaneous with SOP-related actions taken by the federal government, the state government, and the New Jersey Hospital Association. Opportunities persist for increased use of SOPs among non-acute care hospitals and for outpatients.

Disparities in Cardiac Rehabilitation Participation in the United States: A SYSTEMATIC REVIEW AND META-ANALYSIS.

PURPOSE: Phase 2 cardiac rehabilitation (CR) is a class I recommendation for all patients following an acute cardiac event or cardiac surgery according to the The American Heart Association and the American College of Cardiology Foundation. Studies have shown that there are differences in cardiac rehabilitation participation rates between sociodemographic groups. The purpose of this systematic review and meta-analyses was to synthesize quantitative data on the relationship between outpatient cardiac rehabilitation (OCR) attendance and various sociodemographic factors. METHODS: We conducted a search of PubMed, PsycINFO, CINAHL, Google Scholar, Dissertations & Theses A&I, and conference abstracts for observational studies conducted in the United States that fit our inclusion criteria. A total of 21 studies were included in our final review and meta-analyses. RESULTS: Our meta-analyses showed that overall, attenders were younger than nonattenders (mean difference=-3.74 years, 95% CI =-5.87 to -1.61) and the odds of participation were lower among females (OR = 0.59; 95% CI = 0.51-0.69), individuals with a high school degree or less (OR = 0.67; 95% CI = 0.50-0.91), and the uninsured or self-payers (OR = 0.32; 95% CI = 0.14-0.71). Full- or part-time employees were more likely to participate than those not employed (OR = 1.45; 95% CI = 1.08-1.95). CONCLUSIONS: Our systematic review and meta-analyses showed that there are significant sociodemographic disparities in CR participation. On the basis of this knowledge, clinicians and policy makers should focus on identifying and eliminating barriers to participation.

The Health and Social Isolation of American Veterans Denied Veterans Affairs Disability Compensation.

Authors comparatively analyzed health and social isolation between U.S. military veterans denied Veterans Affairs (VA) disability compensation and veterans awarded VA disability compensation. The 2001 National Survey of Veterans was used to create a sample of 4,522 veterans denied or awarded VA disability compensation. Using the Andersen health services utilization model as a conceptual framework, multivariate logistic regression was applied to assess relationships between VA disability compensation award status, three separate domains of health, and correlates of social isolation. Results indicate that denied applicants were more likely than those awarded to have poor overall health (odds ratio [OR] = 1.45, 95% confidence interval [CI]: 1.23, 1.70), and limitations in activities of daily living (OR = 1.12, 95% CI: 1.03, 1.21). Denied applicants' physical functioning (40.3) and mental functioning (41.2) composite summary scores were not clinically different from those of awarded applicants (39.0 and 40.1, respectively), indicating that both were comparably impaired. Veterans denied VA disability compensation had poor health and functional impairments. They also experienced poverty and isolation, suggesting that they may be in need of additional supportive services. Connecting veterans to community resources could be a vital service to provide to all veterans applying for disability compensation.

Case of elevated blood lead in a South Asian family that has used Sindoor for food coloring.

After a routine blood testing, a local pediatrician discovered that a 13-month-old boy had an elevated blood lead level (BLL) of 57 microg/dL. Since the baby was mostly breast-fed, the pediatrician did a blood test on the mother, and the result showed a BLL of 85 microg/dL. As the mother denied any history of pica behavior, the pediatrician suspected a source of lead to which the entire family might have been exposed and tested the father's BLL. The results showed a BLL of 95 microg/dL, and the pediatrician informed the poison center. The subsequent epidemiological investigation revealed that the parents had used a product called Sindoor for food coloring. Laboratory analyses showed that the product contains more than 57.8% of acid-extractable lead by weight. Given the extremely high content of Pb in this product, Sindoor poses a serious risk of lead poisoning if it is used for food coloring.

Health and Health Care Service Utilization Among U.S. Veterans Denied VA Service-Connected Disability Compensation: A Review of the Literature.

UNLABELLED: The general consensus in studies of individuals seeking federal disability compensation is that individuals "denied" disability compensation are healthier than those "awarded." In contrast, studies of military veterans seeking U.S. Department of Veterans Affairs (VA) disability compensation suggest that those "denied" ("denied applicants") may be as impaired as those "awarded" ("awarded applicants"), and likely have critical, albeit unmet health care needs. Moreover, although social isolation among U.S. Veterans has received some attention, its broad influence on health and health care consumption among veterans "denied" VA disability compensation is not well understood. OBJECTIVES: To provide a more thorough understanding of "denied" applicants' health, health care utilization, and social conditions. METHODS: We reviewed published reports of health, health care utilization, and social isolation "relevant" to U.S. Veterans "denied" VA disability compensation. Among 122 research items initially reviewed, a total of 47 met our inclusion criteria and are summarized herein. RESULTS: Compared to veterans "awarded" VA disability compensation, those "denied" have poorer health, use less VA health care, and may experience social isolation. CONCLUSIONS: Veterans "denied" VA disability compensation may comprise a vulnerable subgroup of veterans in need of supportive services. Such needs may be addressed through evidence-based targeted outreach programs.

The association of autism diagnosis with socioeconomic status.

BACKGROUND: In 2007 the Centers for Disease Control and Prevention (CDC) reported a higher prevalence of autism spectrum disorder (ASD) in New Jersey, one of the wealthiest states in the United States, than in other surveillance regions. OBJECTIVE: To examine the association of socioeconomic status (SES) with ASD prevalence. METHODS: Information on eight-year-olds with ASD from four counties was abstracted from school and medical records. US Census 2000 provided population and median household income data. RESULTS: 586 children with ASD were identified: autism prevalence was 10.2/1000, higher in boys than girls (16 vs. 4/1000); higher in white and Asian non-Hispanics than in black non-Hispanics and Hispanics (12.5, 14.0, 9.0, and 8.5/1000, respectively); and higher (17.2/1000 (95% CI 14.0-21.1)) in tracts with median income >US$90,000 than in tracts with median income ≤US$30,000 (7.1 (95% CI 5.7-8.9)). Number of professional evaluations was higher, and age at diagnosis younger, in higher income tracts (p < .001), but both measures spanned a wide overlapping range in all SES levels. In multivariable models race/ethnicity did not predict ASD, but the prevalence ratio was 2.2 (95% CI 1.5-3.1) when comparing highest with lowest income tracts. CONCLUSIONS: In the US state of New Jersey, ASD prevalence is higher in wealthier census tracts, perhaps due to differential access to pediatric and developmental services.
