Lake Shore Drive, 6th Floor, Chicago, IL, 60611, USA, Tel +1 312-503-5618, Email l-bilaver@northwestern.eduBackground: Dry scalp conditions affect a significant portion of the population, including children. Emerging evidence indicates the potential for improvement of atopic symptoms through altering the skin microbiome. Therefore, a topical treatment consisting of probiotic extracts, honey, turmeric, and vitamin B12 was manufactured to improve dry scalp symptomology through sustained balance of the microbiome.Purpose: This interventional clinical study aims to determine the safety and efficacy of the topical treatment in reducing dry scalp symptomology in children 1– 17 years old with dry scalp symptoms.Methods: Participants applied the topical dry scalp treatment 2– 3 times per week for two weeks. Safety and efficacy of the topical treatment was determined through physician assessment using the validated Investigator’s Global Assessment (IGA) scale and the Total Severity Scale (TSS) during pre- and post-treatment clinic visits as well as parent reports at baseline, 1-week midpoint, and 2-week exit.Results: Use of the topical treatment was associated with reduced symptoms of itchiness, dryness, irritation, and flakiness in children. The average IGA score was 3.0 at baseline and 2.0 after treatment, corresponding to a score difference of 1.0 (p < 0.001, 95% CI: 0.7, 1.2). The TSS score difference was 1.9 (p < 0.001, 95% CI: 1.4, 2.4). The total parent-reported scalp severity score decreased from 16.6 (95% CI: 14.8, 18.4) to 12.4 (p < 0.001, 95% CI: 11.0, 13.7) at 2-week exit.Discussion: Study results mirror those reported in a study conducted in adults and point to the safety and efficacy of this natural topical treatment in reducing dry scalp symptomology in children. Based on our data, the combination of probiotic extracts and other anti-inflammatory ingredients appears to improve overall scalp health and appearance, though further studies will need to be conducted to further elucidate the link between clinical improvement and a balanced scalp microbiome.Keywords: dry scalp, dandruff, seborrheic dermatitis, atopic disease, microbiome, probiotic

Background: Potential racial and ethnic disparities related to oral immunotherapy (OIT) have not been fully described among children with food allergy (FA)., Objective: To characterize the differences in attitudes toward, familiarity with, and utilization of OIT among non-Hispanic White (NHW), non-Hispanic Black (NHB), and Hispanic or Latino (H/L) caregivers of children with FA., Methods: Surveys were administered to the caregivers of children enrolled in Food Allergy Outcomes Related to White and African American Racial Differences, a prospective, multisite cohort of children with FA. The distribution of responses by caregiver-reported race and ethnicity was described using an analysis of variance for continuous outcomes and χ 2 tests for categorical outcomes. A logistic regression model was used to determine associations between familiarity with OIT as a treatment option and various other covariates., Results: The NHB and H/L respondents were more frequently not familiar with OIT compared with NHW responders (54.3% and 62.5% vs 9.2%, P < .001). This finding remained true, even after adjusting for household income (odds ratio: 0.1, 95% CI: 0.1-0.4 for NHB participants and odds ratio: 0.1, 95% CI: 0.0-0.3 for H/L participants). NHB and H/L participants more frequently reported that they had never heard of OIT before the survey compared with NHW participants (76.7% and 50.0% vs 26.7%, P < .001). None of the NHB and H/L respondents initiated OIT compared with 14.8% of NHW participants (P < .001)., Conclusion: In the Food Allergy Outcomes Related to White and African American Racial Differences cohort, familiarity with OIT was lower among caregivers of minoritized racial and ethnic groups, even after adjusting for household income., Competing Interests: Disclosures The authors have no conflicts of interest to report., (Copyright © 2024 American College of Allergy, Asthma & Immunology.

Background: There exists strong evidence for the early introduction of peanut to at-risk infants for the primary prevention of peanut allergy. There is a need for educational initiatives to assist in dissemination and implementation of updated clinical guidelines on peanut allergy prevention., Approach: The aim for this project was to create an innovative curriculum for paediatricians on peanut allergy prevention. The Intervention to Reduce Early Allergy (Peanut) in Childhood (iREACH) study was leveraged to recruit paediatricians for a needs assessment. Materials from the iREACH study, including an educational YouTube video and knowledge survey, were evaluated. Applying findings from the needs assessment, an innovative curriculum was developed, and updated knowledge survey questions were developed., Evaluation: The iREACH YouTube video had suboptimal viewing behaviours, and iREACH participants had high baseline knowledge scores that did improve after viewing the video. The majority of respondents to the needs assessment felt that all paediatricians needed access to an effective educational module on peanut allergy prevention, and they wanted a broadly accessible curriculum that incorporated quality media and content segmentation. An online, interactive curriculum was developed that includes clinical cases and games, and updated knowledge questions were created with associated internal structure and reliability evidence, as well as relation to other variables evidence., Implication: The next steps of this project will focus on curriculum implementation and evaluation through a randomised, prospective study with the aim to serve as an educational model for how to integrate specialty-specific guidelines into broader clinical practice through education., (© 2023 Association for the Study of Medical Education and John Wiley & Sons Ltd.)

Background: Definitive treatment for food allergy reactions including anaphylaxis varies widely by reaction severity and socioeconomic status, but little data exist to characterize the relationship between severity, management, and race and ethnicity., Objective: To analyze the differences in reaction severity, epinephrine use, and emergency room (ER) use by race and ethnicity in a large, diverse, food-allergic cohort., Methods: We analyzed intake data from participants in the Food Allergy Outcomes Related to White and African-American Racial Differences cohort on the history of food allergy reactions, severity of the reactions, and management associated with each reaction. We used descriptive statistics as well as mixed-effects logistic and Poisson models to describe the differences in reaction severity, ER visits, and total lifetime epinephrine use by race and ethnicity., Results: A total of 784 children were included in the analysis: 425 (54.2%) were non-Hispanic White, 282 (36.0%) were non-Hispanic Black, and 77 (9.8%) were Hispanic/Latino. Non-Hispanic Black children had increased odds of more severe reactions (odds ratio, 1.7; 95% CI, 1.2-2.3) and higher odds of going to the ER (odds ratio, 2.8; 95% CI, 1.4-5.4). Both non-Hispanic Black (incidence rate ratio, 0.4; 95% CI, 0.3-0.5) and Hispanic/Latino (incidence rate ratio, 0.3; 95% CI, 0.2-0.5) children had lower rates of total lifetime epinephrine use., Conclusions: There are significant disparities in the severity and treatment of food allergy reactions by race and ethnicity, resulting in increased ER use and decreased total lifetime epinephrine use. Equipping parents with resources and tools on management of food allergy reactions may result in decreased disparity in access to definitive care., (Copyright © 2024 American Academy of Allergy, Asthma & Immunology.

Immunogenicity of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) bivalent mRNA-1273.214 vaccine (Original/Omicron B.1.1.529 [BA.1]) is underreported in vulnerable older adults in congregate care settings. In residents of 26 long-term care and retirement homes in Ontario, Canada, humoral (i.e., serum anti-spike and anti-receptor binding domain [anti-RBD]) IgG and IgA antibodies and live SARS-CoV-2 neutralization) and cellular (i.e., CD4 + and CD8 + activation-induced marker spike-specific T cell memory) responses were assessed 7-120 days postvaccination with four monovalent mRNA vaccines (n = 494) or subsequent bivalent mRNA-1273.214 vaccination (fifth vaccine) (n = 557). Within 4 months, anti-spike and anti-RBD antibody levels were similar after monovalent and bivalent vaccination in infection-naïve individuals. Hybrid immunity (i.e., vaccination and natural infection) generally increased humoral responses. After bivalent vaccination, compared to monovalent vaccination, residents with hybrid immunity had elevated anti-spike and anti-RBD IgG and IgA antibodies. Omicron BA.1 antibody-mediated neutralization, and CD8 + T cell memory responses to the Omicron BA.1 spike protein, were also higher after bivalent vaccination. Humoral and cellular responses were, therefore, noninferior within 4 months of bivalent mRNA-1273.214 vaccination compared to monovalent mRNA vaccination. Waning of humoral but not cellular immunity was particularly evident in individuals without hybrid immunity. Continued monitoring of vaccine-associated and hybrid immunity against emerging Omicron variants of concern is necessary to assess longevity of protection., (© 2023 The Authors.

Objectives: To identify factors that contribute to protection from infection with the Omicron variant of SARS-CoV-2 in older adults in nursing and retirement homes., Design: Longitudinal cohort study with retrospective analysis of infection risk., Setting and Participants: 997 residents of nursing and retirement homes from Ontario, Canada, in the COVID in LTC study., Methods: Residents with 3 messenger RNA (mRNA) dose vaccinations were included in the study. SARS-CoV-2 infection was determined by positive nasopharyngeal polymerase chain reaction test and/or circulating antinucleocapsid IgG antibodies. Cumulative probability of Omicron infection after recent COVID-19 was assessed by log-rank test of Kaplan-Meier curves. Cox regression was used to assess risk of Omicron infection by age, sex, mRNA vaccine combination, whether individuals received a fourth dose, as well as recent COVID-19., Results: In total, 171 residents (17.2%) had a presumed Omicron variant SARS-CoV-2 infection between December 15, 2021 (local start of the first Omicron wave) and May 3, 2022. Risk of Omicron infection was not different by age [hazard ratio (95% confidence interval) 1.01 (0.99‒1.02)], or in women compared with men [0.97 (0.70‒1.34)], but infection risk decreased 47% with 3 vaccine doses of mRNA-1273 (Moderna) compared with BNT162b2 (Pfizer) [0.53 (0.31-0.90)], 81% with any fourth mRNA vaccine dose [0.19 (0.12‒0.30)], and 48% with SARS-CoV-2 infection in the 3 months prior to beginning of the Omicron wave [0.52, (0.27‒0.99)]., Conclusions and Implications: Vaccine type (ie, mRNA-1273/Spikevax vs BNT162b2/Cominarty), any fourth vaccine dose, and hybrid immunity from recent COVID-19, were protective against infection with the Omicron variant. These data emphasize the importance of vaccine type, and number of vaccine doses, in maintenance of protective immunity and reduction of risk of Omicron variant breakthrough infection. These findings promote continued public health efforts to support vaccination programs and monitor vaccine immunogenicity in older adults., (Copyright © 2023 The Authors. Published by Elsevier Inc.

Background: Prevention guidelines have changed over the past decade and now recommend the earlier introduction of peanut and egg without delaying the introduction of other food allergens. This paper explored caregiver practices regarding the introduction of food allergens during infancy., Methods: A survey was administered (2021) to a US population-based sample of 3062 caregivers (children 7 months - 3.5 years). Demographics and feeding practices were collected. Weighted frequencies and proportions were calculated using the svyr package in R 4.1. Survey-weighted chi-square statistics and covariate-adjusted, survey-weighted logistic regression models were used for statistical inference., Results: Cow's milk, wheat, and soy were the top three allergens introduced. Peanut and egg were introduced by 17.2% and 15.5% of caregivers before 7 months and 58.8% and 66.4% before 1 year, respectively. The age of peanut and egg introduction differed significantly by race/ethnicity (p < .001) and caregiver age (p < .001). Peanut and egg introduction before 7 months was significantly associated with the increased introduction of other allergenic foods before 1 year (p = <.001; peanut and p = < .001; egg). Caregivers who introduced peanut and egg before 7 months infant age fed an additional mean of 5.4 and 4.5 food allergens, respectively, before 1 year. Few caregivers (0.9%) reported feeding an "early food allergen introduction product" ≥ 3 times, which was significantly associated with parental food allergy (OR = 2.2) and previously seen an allergist (OR = 6.7)., Conclusion: More than half of the caregivers are not introducing peanut by age of one year and one-third are not introducing egg, though an observed shift toward earlier peanut and egg introduction was seen in the past 5 years. Peanut and egg introduction seem to co-occur and are associated with increased intake of other food allergens., (© 2022 The Authors.

Chronic infection with human CMV may contribute to poor vaccine efficacy in older adults. We assessed the effects of CMV serostatus on Ab quantity and quality, as well as cellular memory recall responses, after two and three SARS-CoV-2 mRNA vaccine doses, in older adults in assisted living facilities. CMV serostatus did not affect anti-Spike and anti-receptor-binding domain IgG Ab levels, nor neutralization capacity against wild-type or β variants of SARS-CoV-2 several months after vaccination. CMV seropositivity altered T cell expression of senescence-associated markers and increased effector memory re-expressing CD45RA T cell numbers, as has been previously reported; however, this did not impact Spike-specific CD4+ T cell memory recall responses. CMV-seropositive individuals did not have a higher incidence of COVID-19, although prior infection influenced humoral immunity. Therefore, CMV seropositivity may alter T cell composition but does not impede the durability of humoral protection or cellular memory responses after SARS-CoV-2 mRNA vaccination in older adults., (Copyright © 2022 by The American Association of Immunologists, Inc.)

Background: The past decade has seen increasing opportunities and efforts to integrate quality improvement into health care. Practice facilitation is a proven strategy to support redesign and improvement in primary care practices that focuses on building organizational capacity for continuous improvement. Practice leadership, staff, and practice facilitators all play important roles in supporting quality improvement in primary care. However, little is known about their perspectives on the context, enablers, barriers, and strategies that impact quality improvement initiatives., Objective: This study aimed to develop a framework to enable assessment of contextual factors, challenges, and strategies that impact practice facilitation, clinical measure performance, and the implementation of quality improvement interventions. We also illustrated the application of the framework using a real-world case study., Methods: We developed the TITO (task, individual, technology, and organization) framework by conducting participatory stakeholder workshops and incorporating their perspectives to identify enablers and barriers to quality improvement and practice facilitation. We conducted a case study using a mixed methods approach to demonstrate the use of the framework and describe practice facilitation and factors that impact quality improvement in a primary care practice that participated in the Healthy Hearts in the Heartland study., Results: The proposed framework was used to organize and analyze different stakeholders' perspectives and key factors based on framework domains. The case study showed that practice leaders, staff, and practice facilitators all influenced the success of the quality improvement program. However, these participants faced different challenges and used different strategies. The framework showed that barriers stemmed from patients' social determinants of health, a lack of staff and time, and unsystematic facilitation resources, while enablers included practice culture, staff buy-in, implementation of effective practice facilitation strategies, practice capacity for change, and shared complementary resources from similar, ongoing programs., Conclusions: Our framework provided a useful and generalizable structure to guide and support assessment of future practice facilitation projects, quality improvement initiatives, and health care intervention implementation studies. The practice leader, staff, and practice facilitator all saw value in the quality improvement program and practice facilitation. Practice facilitators are key liaisons to help the quality improvement program; they help all stakeholders work toward a shared target and leverage tailored strategies. Taking advantage of resources from competing, yet complementary, programs as additional support may accelerate the effective achievement of quality improvement goals. Practice facilitation-supported quality improvement programs may be opportunities to assist primary care practices in achieving improved quality of care through focused and targeted efforts. The case study demonstrated how our framework can support a better understanding of contextual factors for practice facilitation, which could enable well-prepared and more successful quality improvement programs for primary care practices. Combining implementation science and informatics thinking, our TITO framework may facilitate interdisciplinary research in both fields., (©Jiancheng Ye, Donna Woods, Jennifer Bannon, Lucy Bilaver, Gayle Kricke, Megan McHugh, Abel Kho, Theresa Walunas.

Background: Racial differences in access to allergen-free food have not been fully described among children with food allergy (FA)., Objective: To examine access to allergen-free foods among Black and White children with FA., Methods: Black and White children with FA were enrolled in Food Allergy Outcomes Related to White and African American Racial Differences (FORWARD), a multisite prospective cohort study at 4 urban US centers. Caregivers completed questionnaires regarding access to allergen-free foods. Univariable statistics described demographics. Bivariable statistics evaluated crude associations with access to allergen-free foods. Multivariable logistic regression evaluated the adjusted effect of race on access to allergen-free foods. Geospatial analyses examined the distribution of race, socioeconomic status, and food desert residence., Results: Among participants (n = 336), White caregivers (88.1%) were more likely to report access to allergen-free foods than Black caregivers (59%) (P < .001). White caregivers were more likely to purchase allergen-free foods online (35.2%) than Black caregivers (12%) (P < .001). Although Black children were more likely to live in a food desert, access to allergen-free food was not related to food desert residence. In the unadjusted analysis, White children were 5.2 times as likely to have access than Black children (P < .001); after adjusting for demographics, this increase in access was no longer significant (P = .08). Other predictors of access to allergen-free foods included online food purchasing, annual household income, respondent education level, milk allergy, and child age >5 years., Conclusion: In the FORWARD cohort, Black children have less access to allergen-free foods than White children, but much of the difference is accounted for by socioeconomic status and other participant characteristics., (Copyright © 2021 American Academy of Allergy, Asthma & Immunology.

Food allergies affect 32 million Americans. Restricted diets due to food allergies can be difficult to maintain especially when the household is food insecure. Food insecurity is defined as the inability to acquire food for household members due to insufficient money or resources for food. The COVID-19 pandemic has caused many people to face food insecurity for the first time with Latinx, Native American, and Black communities disproportionately affected. Because of the increase in food insecurity, this work group developed a survey regarding food insecurity screening. This survey was sent out to a random sample of American Academy of Allergy Asthma & Immunology members to assess food insecurity knowledge and practices. The majority of survey participants did not routinely screen their patients for food insecurity. The biggest barrier identified to screening was lack of knowledge of how to perform a screen and resources available when a patient screened positive. This work group report provides guidance on how to implement and perform a food insecurity screen, including federal resources and assistance programs., (Copyright © 2021 American Academy of Allergy, Asthma & Immunology.

Background: The experiences of Black children with food allergy (FA) are not well characterized, particularly with respect to bullying victimization and other psychosocial outcomes., Objective: To evaluate bullying experiences of Black and White children with FA, including associations with peer relationships, anxiety, and school policies., Methods: Surveys were administered to parents of 252 children with physician-diagnosed FA enrolled in the multisite FORWARD cohort. The surveys assessed demographics, atopic disease, bullying victimization, and school FA management practices and policies. Descriptive statistics of bullying by race were compared by χ 2 tests. Multiple logistic regression analyses adjusting for race, age, parental education, household income, child sex, and multi-FA compared adjusted probabilities of bullying victimization by school policies., Results: Nearly 20% of school-aged children were bullied for FA with no substantial racial differences overall, though for children ages 11 years and up, White children reported higher rates of bullying. However, Black children experienced non-FA-related bullying twice as frequently as White children (38.6% vs 17.7%; P = .002). Most of the caregivers (85.7%) who intervened in their child's bullying reported that it was helpful. Among parents, 17.3% reported that they were teased or bullied owing to their child's FA. More than half of the respondents (54.8%) reported that some allergens are banned from their child's school, most typically peanut. In schools banning peanuts, FA-related bullying was less frequently reported by all students who have food allergy., Conclusion: Bullying owing to FA is common, and caregivers, medical professionals, and school administrators can help reduce bullying by screening for bullying and supporting and educating school policies., (Copyright © 2020.

Background: Although previous studies have focused on unintentional food-related allergic reactions, few have explored the motivation of intentional exposure to a known food allergen, independent of oral food challenges and/or oral immunotherapy. Still, data on the frequency and context of food-related allergic reactions remain sparse., Objective: To identify the frequency and context of food-related allergic reactions among children and adults., Methods: We analyzed surveys from the Patient Registry established by Food Allergy Research and Education. Multivariable logistic regression evaluated characteristics associated with having frequent food-related allergic reactions as well as intentional food-related allergic reactions., Results: Over one-third of 4075 (37.7%) respondents reported having more than 1 food-related allergic reaction per year, and 12.8% reported having 1 reaction per year. Of the 3054 respondents who completed the most recent reaction survey, 9.9% of food allergen exposures were classified as intentional, 82.1% as unintentional, and 4.8% as medically related. Among children with intentional exposures, the most common reason was that the child had never had a serious reaction (50.0%), and among adults, it was the decision to take the risk anyway (47.8%). Cross-contamination was the most commonly cited reason for unintentional exposure (children: 24.1%; adults: 32.2%)., Conclusion: Among patients in a national food allergy registry, reports of food-related allergic reactions were common, and a non-negligible number of intentional reactions were reported. Our findings indicate the need for research on reactions in and out of the emergency department as well as intentional risk-taking behavior., (Copyright © 2020 American Academy of Allergy, Asthma & Immunology.

Background: Food allergy (FA) is an increasing public health concern in the United States, affecting approximately 8% of children and 11% of adults. The United States currently lacks clear requirements for the use of precautionary allergen labeling (PAL) on packaged foods, such as "may contain" or "made on shared equipment." This lack of specific governmental policy results in inconsistent labeling practices and confusion., Objective: This study aimed to understand current knowledge and preferences for PAL statements among FA stakeholders., Methods: A cross-sectional survey was sent to FA stakeholders. Descriptive statistics and associations from logistic regressions were used to assess respondents' knowledge of PAL policy, shopping habits, and preferences around PAL., Results: Of 3008 respondents, 24.2% were able to correctly answer 4 questions surrounding PAL policies. When asked about their shopping habits, the majority of respondents never purchase products with a "May contain traces of allergen" label (85.5%) in comparison with never purchasing products with a "Good manufacturing practices used to segregate ingredients in a facility that also processes allergen" label (35.0%). Their top preferences for a PAL statement were "Not suitable for people with 'blank' allergy" (29.3%) and "May contain" (22.1%). Health care provider discussions around PAL varied and were strongly associated with purchasing behaviors., Conclusions: These results suggest that FA consumers are not aware of PAL policies and make decisions based on the words in the PAL. They prefer having clearer, more specific, and consistent labeling on products, indicating that explicit PAL policies are needed to allow customers to easily identify safe foods., (Published by Elsevier Inc.)

Importance: Describing the economic impact of childhood food allergy in the United States is important to guide public health policies., Objective: To determine the economic impact of childhood food allergy in the United States and caregivers' willingness to pay for food allergy treatment., Design, Setting, and Participants: A cross-sectional survey was conducted from November 28, 2011, through January 26, 2012. A representative sample of 1643 US caregivers of a child with a current food allergy were recruited for participation., Main Outcomes and Measures: Caregivers of children with food allergies were asked to quantify the direct medical, out-of-pocket, lost labor productivity, and related opportunity costs. As an alternative valuation approach, caregivers were asked their willingness to pay for an effective food allergy treatment., Results: The overall economic cost of food allergy was estimated at $24.8 (95% CI, $20.6-$29.4) billion annually ($4184 per year per child). Direct medical costs were $4.3 (95% CI, $2.8-$6.3) billion annually, including clinician visits, emergency department visits, and hospitalizations. Costs borne by the family totaled $20.5 billion annually, including lost labor productivity, out-of-pocket, and opportunity costs. Lost labor productivity costs totaled $0.77 (95% CI, $0.53-$1.0) billion annually, accounting for caregiver time off work for medical visits. Out-of-pocket costs were $5.5 (95% CI, $4.7-$6.4) billion annually, with 31% stemming from the cost of special foods. Opportunity costs totaled $14.2 (95% CI, $10.5-$18.4) billion annually, relating to a caregiver needing to leave or change jobs. Caregivers reported a willingness to pay of $20.8 billion annually ($3504 per year per child) for food allergy treatment., Conclusions and Relevance: Childhood food allergy results in significant direct medical costs for the US health care system and even larger costs for families with a food-allergic child.

Objective: To examine whether and to what extent specific chronic health conditions place young children at risk of maltreatment., Methods: The study used a sample of Illinois children (born between January 1990 and March 1996) who were through age 3 continuously enrolled in Medicaid, a public health insurance program for low-income families. The study used "paid claims" data and ICD-9-CM health codes to identify children with one or more of three chronic conditions: chronic physical illness, developmental delay/mental retardation (dd/mr), and behavior/mental health conditions (b/mh). The analysis used Cox proportional hazard models to estimate the risk of substantiated child maltreatment that each of these health conditions confer on children under age 6., Results: Among children under age 6, 24.1% had chronic physical health conditions, 6.1% had b/mh conditions, and 4.2% had dd/mr. Among the children, 11.7% were maltreated (abused or neglected). Children with b/mh conditions were 1.95 times more likely than children without such conditions to be victims of child abuse or neglect. Children with chronic physical health conditions were 1.1 time more likely to be maltreated (p
