OBJECTIVES: To investigate factors associated with poor sleep quality and daytime sleepiness in women living in the United States. METHODS: Data are presented from the National Sleep Foundation's 2007 Sleep in America Poll that included 959 women (18-64 years of age) surveyed by telephone about their sleep quality, daytime sleepiness, and sociodemographic, health, and lifestyle factors. RESULTS: Poor sleep quality was reported by 27% and daytime sleepiness was reported by 21% of respondents. Logistic multivariate regression analyses revealed that poor sleep quality and daytime sleepiness were both independently associated with poor health, having a sleep disorder, and psychological distress. Also, multivariate analyses showed that women who consumed more caffeinated beverages and those who had more than one job were more likely to report poor sleep quality but not daytime sleepiness. Daytime sleepiness, on the other hand, was independently associated with being black/African American, younger, disabled, having less education, and daytime napping. CONCLUSIONS: Poor sleep quality and daytime sleepiness are common in American women and are associated with health-related, as well as sociodemographic, factors. Addressing sleep-related complaints in women is important to improve their daytime functioning and quality of life. [ABSTRACT FROM AUTHOR]

Shorter sleep duration can negatively impact children's daytime functioning and health. Latino children living near urban areas in the Mainland U.S. and Island Puerto Rico (PR) can be exposed to urban poverty and sociocultural stressors that challenge optimal sleep outcomes. Interventions to improve urban Latino children's sleep health should consider families' cultural background and environmental context to enhance acceptability and feasibility. This work describes our stepwise, multimethod approach to adapting a culturally and contextually tailored "School Intervention to Enhance Latino Students' Time Asleep (SIESTA)" for sixth- to eighth-grade Latino children residing in Greater Providence and San Juan and findings from a pilot randomized control trial (RCT) demonstrating SIESTA's efficacy. Results indicated high acceptability and greater improvement of sleep duration and behaviors in SIESTA versus control participants. The SIESTA shows potential to improve sleep outcomes in urban Latino middle schoolers. Results will inform a large-scale RCT to evaluate SIESTA's effectiveness and barriers to implementation., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objectives: At the peak of COVID-19, adolescent life was disrupted as schools adapted their instructional approaches such as online, in-person, or hybrid instruction. We and others have previously commented on how these shifts facilitated longer, later and (more developmentally appropriate) sleep. Here, we report how sleep contributed to associations between remote instruction and broader academic well-being (e.g., cognitive function, school connectedness, and stress)., Methods: Adolescents from all 50 U.S. states (n = 4068) completed online self-report surveys in fall 2020. Instructional approach was operationalized from fully in-person instruction to fully asynchronous online education. Sleep parameters included sleep timing and duration, sleep disturbances, and sleep-related impairments. Perceived academic well-being was defined as cognitive function, school connectedness, and school-related stress. Sleep and perceived academic well-being are examined across instructional approaches, in their association, and in structural models., Results: Sleep and perceived academic well-being differed between hybrid and online instruction groups. Less variable or disturbed sleep was associated both with in-person instruction, and with positive outcomes in cognitive function, school connectedness, and stress domains. Sleep mediated a substantial portion of variance in perceived academic well-being attributable to instructional approach., Conclusion: These data highlight the need to protect both healthy sleep and in-person instruction. Appropriate sleep timing and duration, fewer sleep disturbances and sleep-related impairments accounted for a substantial degree of variance in the association between remote instruction on academic outcomes. While many students experienced "lost learning" because of COVID-19, this study joins a broader discussion of ensuring developmentally appropriate school-start times to support both sleep and achievement., Competing Interests: Declaration of conflicts of interest None., (Copyright © 2024 National Sleep Foundation.

Objectives: Sleep disruption is prevalent among children placed in foster care, elevating risk for a range of deleterious outcomes. Theoretically, achieving permanency via adoption may have a positive influence on children's sleep via the presence of various factors, but little is known about the sleep health of children adopted from foster care, including predictors and moderators of sleep health., Method: The current study included 226 parents who adopted a child from foster care in the U.S. (aged 4-11 years) within the past two years and a propensity score matched sample of 379 caregivers of children currently in foster care. Both samples completed online questionnaires about their child's sleep, physical, and mental health., Results: Comparatively, children in foster care experienced more nightmares, night terrors, moving to someone else's' bed during the night, and worse overall sleep quality, whereas adopted children were reported to experience significantly more nighttime awakenings. In the adopted sample, a greater number of prior foster placements unexpectedly predicted lower total sleep disturbance scores, but this relationship was moderated by parent-child interactions around sleep. In general, greater parental involvement in children's sleep was associated with lower levels of child sleep disturbance., Conclusions: Findings suggest that while specific sleep problems might remit after children in foster care achieve permanence, nighttime sleep fragmentation often persists. Parent-child interactions surrounding sleep may be pivotal in improving sleep health in this population.

Study Objectives: Little is known about sleep health among staff in the US juvenile justice system. Poor sleep health is associated with negative mental and physical health, which may impact daily interactions and treatment of detained youth. The current study explored sleep-wake patterns and sleep health knowledge of Department of Juvenile Services (DJS) staff in Maryland (MD)., Methods: DJS Staff ( N = 218) were invited to complete a survey that queried staff on their own sleep-wake patterns, job role and schedule, and knowledge of youth sleep needs. Descriptive analyses and multivariate analyses of variance (MANCOVA) were conducted to summarize workers' sleep-wake patterns and examine differences by staff position and schedule., Results: Fifty-one percent of staff served as RAs who directly supervise the youth. Just over half (55%) worked in detention and 45% in treatment facilities. Staff reported sleeping 7.24 hours (SD = 4.10) on workdays and 8.59 hours (SD = 2.69) on non-workdays. RA staff working night/rotating versus day shifts reported the most sleep irregularity with larger weekend oversleep times. A little more than half of the staff (53.9%) were knowledgeable regarding youth sleep health with differences by position type., Conclusions: Findings show that DJS staff are meeting recommended sleep duration guidelines but are still experiencing sleep schedule and time in bed irregularity. Knowledge variability of youth sleep health across staff may necessitate focused educational programming. Overall, this study may inform future development and prioritization of sleep and circadian health interventions and educational campaigns for staff who work with detained juveniles.

Background: Using the reaction history in logistic regression and machine learning (ML) models to predict penicillin allergy has been reported based on non-US data., Objective: We developed ML positive penicillin allergy testing prediction models from multisite US data., Methods: Retrospective data from 4 US-based hospitals were grouped into 4 datasets: enriched training (1:3 case-control matched cohort), enriched testing, nonenriched internal testing, and nonenriched external testing. ML algorithms were used for model development. We determined area under the curve (AUC) and applied the Shapley Additive exPlanations (SHAP) framework to interpret risk drivers., Results: Of 4777 patients (mean age 60 [standard deviation: 17] years; 68% women, 91% White, and 86% non-Hispanic) evaluated for penicillin allergy labels, 513 (11%) had positive penicillin allergy testing. Model input variables were frequently missing: immediate or delayed onset (71%), signs or symptoms (13%), and treatment (31%). The gradient-boosted model was the strongest model with an AUC of 0.67 (95% confidence interval [CI]: 0.57-0.77), which improved to 0.87 (95% CI: 0.73-1) when only cases with complete data were used. Top SHAP drivers for positive testing were reactions within the last year and reactions requiring medical attention; female sex and reaction of hives/urticaria were also positive drivers., Conclusions: An ML prediction model for positive penicillin allergy skin testing using US-based retrospective data did not achieve performance strong enough for acceptance and adoption. The optimal ML prediction model for positive penicillin allergy testing was driven by time since reaction, seek medical attention, female sex, and hives/urticaria., (Copyright © 2024 American Academy of Allergy, Asthma & Immunology.

When approaching a case of apparent drug allergy, the consulting clinician should consider a broad differential diagnosis. This article presents a series of cases that could be commonly referred to an allergist for assessment as "drug allergy," however, a real diagnosis exists that mandates a different diagnostic and treatment strategy, including a case of inducible laryngeal obstruction, multiple drug intolerance syndrome, viral rash, seizure due to metastatic malignancy, and hemophagocytic lymphohistiocytosis initially diagnosed as drug reaction and eosinophilia with systemic symptoms. The initial misdiagnoses of these patients delayed or interfered with their medical care, emphasizing the importance of accurate diagnoses for the benefit of our patients., (Copyright © 2024 American Academy of Allergy, Asthma & Immunology.

Objectives: To test whether adolescents' mental health during the COVID-19 pandemic is associated with the combination of their instructional approach(es) and their sleep patterns., Design: Cross-sectional., Setting: Adolescents were recruited through social media outlets in October and November 2020 to complete an online survey., Participants: Participants were 4442 geographically and racially diverse, community-dwelling students (grades 6-12, 51% female, 36% non-White, 87% high schoolers)., Measurements: Participants completed items from the PROMIS Pediatric Depressive Symptoms and Anxiety scales. Participants reported their instructional approach(es), bedtimes, and wake times for each day in the past week. Participants were categorized into five combined instructional approach groups. Average sleep opportunity was calculated as the average time between bedtime and waketime. Social jetlag was calculated as the difference between the average sleep midpoint preceding non-scheduled and scheduled days., Results: Emotional distress was elevated in this sample, with a large proportion of adolescents reporting moderate-severe (T-score ≥ 65) levels of depressive symptoms (49%) and anxiety (28%). There were significant differences between instructional approach groups, such that adolescents attending all schooldays in-person reported the lowest depressive symptom and anxiety T-scores (P < .001, η p 2 = .012), but also the shortest sleep opportunity (P < .001, η p 2 = .077) and greatest social jetlag (P < .001, η p 2 = .037) of all groups. Adolescents attending school in person, with sufficient sleep opportunity (≥8-9 hours/night) and limited social jetlag (<2 hours) had significantly lower depressive (η p 2 = .014) and anxiety (η p 2 = .008) T-scores than other adolescents., Conclusions: Prioritizing in-person education and promoting healthy sleep patterns (more sleep opportunity, more consistent sleep schedules) may help bolster adolescent mental health., Competing Interests: Declaration of conflicts of interest None., (Published by Elsevier Inc.)

Across all settings, women self-report more drug allergies than do men. Although there is epidemiologic evidence of increased drug allergy labeling in postpubertal females, the evidence base for female sex as a risk factor for true immune-mediated drug hypersensitivity reactions (DHRs), particularly in fatal drug-induced anaphylaxis, is low. A focus on the known immunologic mechanisms described in immediate and delayed DHR, layered on known hormonal and genetic sex differences that drive other immune-mediated diseases, could be the key to understanding biological sex variations in DHR. Particular conditions that highlight the impact of drug allergy in women include (1) pregnancy, in which a drug allergy label is associated with increased maternal and fetal complications; (2) multiple drug intolerance syndrome, associated with anxiety and depression; and (3) female-predominant autoimmune medical conditions in the context of mislabeling of the drug allergy or increased underlying risk. In this review, we describe the importance of drug allergy in the female population, mainly focusing on the epidemiology and risk, the mechanisms, and the associated conditions and psychosocial factors. By performing a detailed analysis of the current literature, we provide focused conclusions and identify existing knowledge gaps that should be prioritized for future research., (Copyright © 2023 American Academy of Allergy, Asthma & Immunology.

Objective: Few studies have explored sleep health and environmental influences on sleep and circadian health within juvenile justice facilities. The current study aims to describe sleep and circadian health of adolescents living in detention and treatment facilities., Methods: Youth (N = 62) were recruited from 11 Department of Juvenile Services facilities. They completed a novel Youth Sleep and Daytime Behavior Questionnaire, daily sleep diary for seven consecutive mornings, and a brief poststudy interview. Healthcare staff completed a Youth Health Background survey for each participating youth. Facilities' 24-hour schedules were also obtained., Results: Descriptive analyses were performed to capture the youths' sleep-wake experience while residing in Department of Juvenile Services facilities. Youth are obtaining the recommended total sleep time (M=8.9 hours, SD=1.2 hours) of 8-10 hours per night. However, they are taking twice as long to fall asleep (M=47 minutes SD=59 minutes) compared to the recommended sleep onset latency of 10-20 minutes. Youths' perceptions reveal potential reasons for long sleep onset latencies, including early facility sleep-wake schedules (78%) and overhead lights (60%) remaining on throughout the night. Furthermore, 37% of youth received facility-ordered behavioral sleep assessments, 36% were taking exogenous melatonin, and the majority of youth were prescribed at least one psychotropic medication., Conclusions: Findings suggest sleep-wake schedules and light exposure may be associated with an increase in symptoms of insomnia and/or circadian dysregulation. Based on the findings, facility-wide interventions are needed to improve the youths' sleep health., Competing Interests: Declaration of conflicts of interest None., (Copyright © 2023 National Sleep Foundation.

The coronavirus disease 2019 (COVID-19) pandemic has disproportionately affected disadvantaged populations. Many of the factors related to the disproportionate impact on underserved communities are related to social determinants of health, defined by the World Health Organization as the nonmedical factors that influence health outcomes. They include the wider set of forces and systems shaping the conditions of daily life. This work explores the interrelationships between social determinants of health and access to care, health care professional and supply shortages, social and environmental factors, health behaviors, vaccine uptake, and treatment options on COVID-19 health outcomes. Increased awareness of inequities, learning from failures, and leveraging new opportunities to partner with key stakeholders in underserved communities create empowerment and preparedness to face new challenges., (Copyright © 2023 American Academy of Allergy, Asthma & Immunology.

This guidance updates 2021 GRADE (Grading of Recommendations Assessment, Development and Evaluation) recommendations regarding immediate allergic reactions following coronavirus disease 2019 (COVID-19) vaccines and addresses revaccinating individuals with first-dose allergic reactions and allergy testing to determine revaccination outcomes. Recent meta-analyses assessed the incidence of severe allergic reactions to initial COVID-19 vaccination, risk of mRNA-COVID-19 revaccination after an initial reaction, and diagnostic accuracy of COVID-19 vaccine and vaccine excipient testing in predicting reactions. GRADE methods informed rating the certainty of evidence and strength of recommendations. A modified Delphi panel consisting of experts in allergy, anaphylaxis, vaccinology, infectious diseases, emergency medicine, and primary care from Australia, Canada, Europe, Japan, South Africa, the United Kingdom, and the United States formed the recommendations. We recommend vaccination for persons without COVID-19 vaccine excipient allergy and revaccination after a prior immediate allergic reaction. We suggest against >15-minute postvaccination observation. We recommend against mRNA vaccine or excipient skin testing to predict outcomes. We suggest revaccination of persons with an immediate allergic reaction to the mRNA vaccine or excipients be performed by a person with vaccine allergy expertise in a properly equipped setting. We suggest against premedication, split-dosing, or special precautions because of a comorbid allergic history., (Crown Copyright © 2023. Published by Elsevier Inc. All rights reserved.)

Objective: The disparity of problems, impairments, and disorders among children in foster care is well-documented and spans virtually every domain of functioning. Sleep, however, has received minimal attention among this vulnerable group, which is concerning given the multitude of ways sleep affects children's development, health, and behavior., Methods: A total of 485 foster caregivers from across the United States completed a survey including quantitative items and qualitative, open-ended questions about sleep and related health and behavior for one child (M = 6.4 years, SD = 2.2; range 4-11 years) currently in their care., Results: Overall, caregivers reported developmentally appropriate child sleep and wake times; however, difficulty falling asleep (avg. 46 min per night) and staying asleep (avg. 34 min awake overnight) were common. Additionally, a high prevalence of sleep-related problems was reported including moving to someone else's bed during the night (85.8%), nightmares (51.2%), sleep terrors (26.4%), snoring (32.8%), bedwetting (31.6%), and teeth grinding (21.8%). Qualitative responses indicated emotional and behavioral challenges at bedtime, particularly elevated fear, and anxiety., Conclusions: Findings are consistent with previous work finding significant health disparities among children placed in foster care. Results highlight a need for trauma-informed, behavioral sleep interventions for this pediatric population which might serve to reduce other health disparities., (© The Author(s) 2022.

Purpose of Review: The COVID-19 vaccines have proved essential in our defense against the COVID-19 pandemic. However, concerns regarding allergic reactions to the vaccines persist to this day. Herein, we review the data regarding the frequency of allergic reactions to the COVID-19 vaccines, the epidemiology, and the management of patients reporting vaccine allergic reactions., Recent Findings: Although initial reports emphasized a high risk of anaphylaxis to the COVID-19 vaccines, more recent data demonstrate similar rates of anaphylaxis to the COVID-19 vaccines as to other vaccines. Alternative explanations for increased rates of apparent allergic reactions are discussed, including the role for stress-related and nocebo responses. COVID-19 vaccines and mRNA vaccine technology are overwhelmingly safe and well-tolerated by most patients. Careful history and case review will enable the discerning physician to safely vaccinate most patients. Rare patients with objective signs and symptoms of anaphylaxis may be candidates for alternatives to vaccination including monoclonal antibodies., (© 2023.

Purpose of Review: We review the literature and discuss the logistics of testing pregnant patients for penicillin allergy., Recent Findings: As in the general population, pregnant patients commonly report a penicillin allergy, but most patients are able to tolerate penicillin. Avoidance of beta-lactams in pregnancy is associated with increased morbidity: longer hospitalizations, more frequent infections, and more complications. Penicillin allergy testing is safe in pregnant patients, and obstetricians are eager for allergists to offer this procedure to their patients. As allergists, we can improve our patients' health outcomes by offering penicillin allergy testing in our practices. The protocols for testing both with and without skin testing in pregnant patients have been studied, and future studies will continue to clarify the safety and efficacy of penicillin allergy delabeling in pregnant patients., (© 2023.

Background: Although immediate potentially allergic reactions have been reported after dose 1 of mRNA coronavirus disease 2019 (COVID-19) vaccines, comprehensively defined subtypes have not been clearly distinguished., Objective: To define distinct clinical phenotypes of immediate reactions after dose 1 of mRNA COVID-19 vaccination, and to assess the relation of clinical phenotype to mRNA COVID-19 vaccine second dose tolerance., Methods: This retrospective study included patients with 1 or more potentially allergic symptoms or signs within 4 hours of receiving dose 1 of an mRNA COVID-19 vaccine and assessed by allergy/immunology specialists from 5 U.S. academic medical centers (January-June 2021). We used latent class analysis-an unbiased, machine-learning modeling method-to define novel clinical phenotypes. We assessed demographic, clinical, and reaction characteristics associated with phenotype membership. Using log-binomial regression, we assessed the relation between phenotype membership and second dose tolerance, defined as either no symptoms or mild, self-limited symptoms resolving with antihistamines alone. A sensitivity analysis considered second dose tolerance as objective signs only., Results: We identified 265 patients with dose-1 immediate reactions with 3 phenotype clusters: (1) Limited or Predominantly Cutaneous, (2) Sensory, and (3) Systemic. A total of 223 patients (84%) received a second dose and 200 (90%) tolerated their second dose. Sensory cluster (all patients had the symptom of numbness or tingling) was associated with a higher likelihood of second dose intolerance, but this finding did not persist when accounting for objective signs., Conclusions: Three novel clinical phenotypes of immediate-onset reactions after dose 1 of mRNA COVID-19 vaccines were identified using latent class analysis: (1) Limited or Predominantly Cutaneous, (2) Sensory, and (3) Systemic. Whereas these clinical phenotypes may indicate differential mechanistic etiologies or associations with subsequent dose tolerance, most individuals proceeding to their second dose tolerated it., (Copyright © 2022 American Academy of Allergy, Asthma & Immunology.

For persons with immediate allergic reactions to mRNA COVID-19 vaccines, skin testing (ST) to the vaccine/excipients (polyethylene glycol[PEG] and polysorbate 80 [PS]) has been recommended, but has unknown accuracy. To assess vaccine/excipient ST accuracy in predicting all-severity immediate allergic reactions upon re-vaccination, systematic review was performed searching Medline, EMBASE, Web of Science, and the WHO global coronavirus database (inception-Oct 4, 2021) for studies addressing immediate (≤4 h post-vaccination) all-severity allergic reactions to 2nd mRNA COVID-19 vaccination in persons with 1st dose immediate allergic reactions. Cases evaluating delayed reactions, change of vaccine platform, or revaccination without vaccine/excipient ST were excluded. Meta-analysis of diagnostic testing accuracy was performed using Bayesian methods. The GRADE approach evaluated certainty of the evidence, and QUADAS-2 assessed risk of bias. Among 20 studies of mRNA COVID-19 first dose vaccine reactions, 317 individuals underwent 578 ST to any one or combination of vaccine, PEG, or PS, and were re-vaccinated with the same vaccine. Test sensitivity for either mRNA vaccine was 0.2 (95%CrI 0.01-0.52) and specificity 0.97 (95%CrI 0.9-1). PEG test sensitivity was 0.02 (95%CrI 0.00-0.07) and specificity 0.99 (95%CrI 0.96-1). PS test sensitivity was 0.03 (95%CrI 0.00-0.0.11) and specificity 0.97 (95%CrI 0.91-1). Combined for use of any of the 3 testing agents, sensitivity was 0.03 (95%CrI 0.00-0.08) and specificity was 0.98 (95%CrI 0.95-1.00). Certainty of evidence was moderate. ST has low sensitivity but high specificity in predicting all-severity repeat immediate allergic reactions to the same agent, among persons with 1st dose immediate allergic reactions to mRNA COVID-19 vaccines. mRNA COVID-19 vaccine or excipient ST has limited risk assessment utility., (© 2022 European Academy of Allergy and Clinical Immunology and John Wiley & Sons Ltd.)

Diphenhydramine is one of the most widely available, longest-used antihistamine medications but has many side effects including sedation and risk of toxicity in overdose including cardiac toxicity. It is frequently inappropriately used when newer, more favorable antihistamine medications are available. Second-generation antihistamines are also widely available and affordable, with many of the same desired effects as diphenhydramine and fewer, if any, of the undesirable side effects. Because of the negative side effects and wide availability of alternative antihistamine medications, it is definitively time to move on from diphenhydramine., (Copyright © 2022 American Academy of Allergy, Asthma & Immunology.

Objective: Commonly held beliefs about sleep unsupported by scientific evidence (ie, myths) among adolescents and their parents/caregivers may adversely influence sleep-related attitudes and behaviors among adolescents. Thus, identifying such myths with the goal of developing effective evidence-based counter-messages has the potential to improve sleep health in adolescents., Method: We identified myths with a panel of adolescent sleep health experts (n = 12) using the Delphi method in three sequential steps: (1) focus groups; (2) online discussion; and (3) closed-ended questionnaires with which the experts rated myths on: (1) falseness and (2) public health significance using 5-point Likert scales ranging from 1 (not at all false/important for public health) to 5 (extremely false/important for public health). Next, we explored the prevalence of the myths among a demographically diverse sample of parents/caregivers of adolescents in the United States. Finally, we report the counterevidence to refute each myth., Results: Ten myths about adolescent sleep were identified by the experts using the Delphi method. The most prevalent myths were the beliefs that (1) "Going to bed and waking up late on the weekends is no big deal for adolescents, as long as they get enough sleep during that time," reported by 74% of parents/caregivers; (2) "If school starts later, adolescents will stay up that much later," reported by 69% of parents/caregivers; and (3) "Melatonin supplements are safe for adolescents because they are natural," reported by 66% of parents/caregivers., Conclusion: Parents/caregivers have the potential to serve as sleep health advocates for their adolescent and support their adolescent's sleep health behaviors. Our study found that many parents/caregivers endorse myths about adolescent sleep that may hinder their ability to support their adolescent's sleep health. Future research may explore methods for promoting evidence-based beliefs about adolescent sleep among parents/caregivers., (Copyright © 2022 National Sleep Foundation. Published by Elsevier Inc.

Objective: Evidence of poor sleep health among children in foster care continues to mount, but information about whether and how sleep problems are addressed is unavailable. The goal of this study was to begin to fill these significant knowledge gaps., Methods: Four hundred eighty-five foster caregivers from across the United States completed a survey focused on the sleep health of one child, 4 to 11 years ( M = 6.4; SD = 2.2) currently in their care. Caregivers provided quantitative and qualitative responses to questions regarding training, information, and services received in relation to their child's sleep. Caregivers also reported on the factors and strategies they perceived as most important for helping children in their care sleep well., Results: Only 13% of caregivers reported receiving any information/education about sleep from agencies or case workers, whereas 55% had sought help from a health provider related to their child's sleep. Nearly half of all caregivers (46%) reported giving their child melatonin. Caregivers reported that a bedtime routine/consistency, reassurance of safety/love, and a calming environment were most important for helping their child sleep well. A recurrent theme in qualitative responses was a need to mitigate child fear/anxiety at night., Conclusion: Children in foster care face a range of risk factors that increase the likelihood of poor/insufficient sleep, but these findings suggest this critical aspect of health requires greater clinical and research attention. As these data were collected during the initial months of the COVID-19 pandemic, replication studies are necessary., Competing Interests: Disclosure: The authors declare no conflict of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Study Objectives: To describe the development of circadian rest-activity rhythms (CRARs) during infancy in a racially diverse cohort., Methods: We studied 414 infants from the Nurture birth cohort (51.2% female, 65.2% Black) who wore actigraphs on their left ankles for 4 days and nights at 3, 6, 9, and 12 months. We quantified CRARs using cosinor and non-parametric circadian rhythm analysis, and investigated change in CRARs over time, comparing 6, 9, and 12 months to CRARs at 3 months. We adjusted for baseline and time-varying covariates and used function-on-scalar regression (FOSR) to identify the specific times of day at which activity changes occurred., Results: Across the first year, daily mean and peak activity levels and day-to-day activity level regularity increased, and activity level fragmentation and nighttime activity decreased. Only at 9 months, compared to at 3 months, did timing of peak activity levels and the most active periods shift later, while timing of least active periods shifted earlier. FOSR analyses showed that mean activity levels decreased during nighttime hours and increased during daytime hours, with the most pronounced changes at 9 months., Conclusions: Among racially diverse infants, CRARs became more robust, stable, and less fragmented over time. Findings suggest the greatest change from 3-month CRARs occurs at 9 months, which may be a key period of CRAR development. This and future research will contribute to our understanding of normative infant CRAR development in diverse populations and enable us to identify infants who may benefit from intervention., (© The Author(s) 2022.

Study Objectives: Trauma exposure likely contributes to poor sleep, but relatively few studies have empirically tested this, instead focusing on posttraumatic stress disorder. Moreover, little is known about sex differences in sleep after trauma. The current study used a cross-sectional and retrospective design to test hypotheses that trauma exposure would be associated with subsequent insomnia symptoms, particularly among women, even after accounting for important covariates., Method: Data from Wave 3 (1993-1996) of the Baltimore Epidemiologic Catchment Area Study (N = 1920) were used to examine associations between remote (prior to past year) and recent (past year) trauma and current sleep disturbance (insomnia, hypersomnia symptoms) in the total sample (M age = 55, 63.2% women, 57.7% white), and separately in men and women. Sensitivity analyses were conducted among individuals with no pretrauma sleep disturbance to examine incident sleep disturbance., Results: Among all participants, both remote (odds ratio [OR] = 1.95, 95% confidence interval [CI] [1.34, 2.85]) and recent (OR = 1.94, 95% CI [1.31, 2.87]) trauma exposure were associated with increased odds of insomnia (OR = 2.41, 95% CI [1.54, 3.76]) but not hypersomnia. Associations between trauma and insomnia were particularly strong among women, but null among men. The relationship between trauma exposure and insomnia symptoms persisted among individuals with no pretrauma history of insomnia., Conclusion: Results suggest women may be vulnerable to insomnia symptoms as sequelae of trauma. Future research should examine prospective associations between trauma and sleep in larger samples and how assessment and treatment of insomnia among women trauma survivors reduces the public health impact of trauma and poor sleep., (Copyright © 2021 National Sleep Foundation.

Adolescent caffeine use and its implications for developmental changes in sleep and circadian rhythms is under-researched. A majority of adolescents report consuming caffeine and yet the United States has not established federal guidelines for this age group. This widely used stimulant is primarily studied using self-report methodologies; however, there is no standardized method for collecting self-report caffeine data and past studies' findings have limited generalizability and comparability, making it challenging to examine the effects of caffeine use on adolescents' sleep. This review discusses methods and measures used for assessing caffeine in the field with adolescents: questionnaires, interviews, and diaries. Based on the review, recommendations for future methodologies and approaches are discussed., Competing Interests: Conflicts of interest The authors do not have any conflicts of interest to disclose., (Copyright © 2021.

Importance: Vaccination against SARS-CoV-2 is a highly effective strategy to prevent infection and severe COVID-19 outcomes. The best strategy for a second dose of vaccine among persons who had an immediate allergic reaction to their first SARS CoV-2 vaccination is unclear., Objective: To assess the risk of severe immediate allergic reactions (eg, anaphylaxis) to a second dose of SARS-CoV-2 mRNA vaccine among persons with immediate allergic reactions to their first vaccine dose., Data Sources: MEDLINE, Embase, Web of Science, and the World Health Organization Global Coronavirus database were searched from inception through October 4, 2021., Study Selection: Included studies addressed immediate allergic reactions of any severity to a second SARS-CoV-2 vaccine dose in persons with a known or suspected immediate allergic reaction (<4 hours after vaccination) after their first SARS-CoV-2 vaccine dose. Studies describing a second vaccine dose among persons reporting delayed reactions (>4 hours after vaccination) were excluded., Data Extraction and Synthesis: Paired reviewers independently selected studies, extracted data, and assessed risk of bias. Random-effects models were used for meta-analysis. The GRADE (Grading of Recommendation, Assessment, Development, and Evaluation) approach evaluated certainty of the evidence., Main Outcomes and Measures: Risk of severe immediate allergic reaction and repeated severe immediate allergic reactions with a second vaccine dose. Reaction severity was defined by the reporting investigator, using Brighton Collaboration Criteria, Ring and Messmer criteria, World Allergy Organization criteria, or National Institute of Allergy and Infectious Diseases criteria., Results: Among 22 studies of SARS-CoV-2 mRNA vaccines, 1366 individuals (87.8% women; mean age, 46.1 years) had immediate allergic reactions to their first vaccination. Analysis using the pooled random-effects model found that 6 patients developed severe immediate allergic reactions after their second vaccination (absolute risk, 0.16% [95% CI, 0.01%-2.94%]), 232 developed mild symptoms (13.65% [95% CI, 7.76%-22.9%]), and, conversely, 1360 tolerated the dose (99.84% [95% CI, 97.09%-99.99%]). Among 78 persons with severe immediate allergic reactions to their first SARS-CoV-2 mRNA vaccination, 4 people (4.94% [95% CI, 0.93%-22.28%]) had a second severe immediate reaction, and 15 had nonsevere symptoms (9.54% [95% CI, 2.18%-33.34%]). There were no deaths. Graded vaccine dosing, skin testing, and premedication as risk-stratification strategies did not alter the findings. Certainty of evidence was moderate for those with any allergic reaction to the first dose and low for those with severe allergic reactions to the first dose., Conclusions and Relevance: In this systematic review and meta-analysis of case studies and case reports, the risk of immediate allergic reactions and severe immediate reactions or anaphylaxis associated with a second dose of an SARS-CoV-2 mRNA vaccine was low among persons who experienced an immediate allergic reaction to their first dose. These findings suggest that revaccination of individuals with an immediate allergic reaction to a first SARS-CoV-2 mRNA vaccine dose in a supervised setting equipped to manage severe allergic reactions can be safe.

In fall 2019, California passed and signed into law SB328, the first US statewide legislation explicitly designed to protect adolescent sleep health by requiring most California public school districts to start no earlier than 8:00 AM for middle schools and 8:30 AM for high schools. Recognizing the unique opportunity presented by the bill's 3-year implementation period, a group of experts in adolescent sleep and school start times held a virtual summit on January 22-23, 2021 to (1) summarize the research on adolescent sleep and school start time change; (2) develop recommendations for relevant, refined, and innovative research areas and research questions; (3) provide input regarding research design, methodology, and implementation; and (4) offer a forum for networking, exchanging ideas, and establishing interdisciplinary research collaborations. Participants represented a multidisciplinary range of academic backgrounds including sleep and circadian biology, neuroscience, education, medicine, public health, mental health, safety, public policy, economics, implementation science, criminology, diversity studies, and science communication. This paper summarizes summit presentations regarding current knowledge on adolescent sleep health and school start times and key research recommendations from small group workshops on topics including research design and tools, methodological issues, sleep health disparities, logistical challenges in conducting school-based research, public-health impact, and novel and expanded approaches to research., Competing Interests: Declaration of conflict of interest Dr. Pelayo reports grants from the American Academy of Sleep Medicine, and from the National Sleep Foundation during the conduct of the study; he also served on the boards of the nonprofit organizations Start School Later and the National Sleep Foundation and volunteered as chair of the American Academy of Sleep Medicine's Political Action Committee.

Study Objectives: To examine associations among instructional approaches, school start times, and sleep during the COVID-19 pandemic in a large, nationwide sample of U.S. adolescents., Methods: Cross-sectional, anonymous self-report survey study of a community-dwelling sample of adolescents (grades 6-12), recruited through social media outlets in October/November 2020. Participants reported on instructional approach (in-person, online/synchronous, online/asynchronous) for each weekday (past week), school start times (in-person or online/synchronous days), and bedtimes (BT) and wake times (WT) for each identified school type and weekends/no school days. Sleep opportunity was calculated as BT-to-WT interval. Night-to-night sleep variability was calculated with mean square successive differences., Results: Respondents included 5,245 racially and geographically diverse students (~50% female). BT and WT were earliest for in-person instruction; followed by online/synchronous days. Sleep opportunity was longer on individual nights students did not have scheduled instruction (>1.5 h longer for online/asynchronous than in-person). More students obtained sufficient sleep with later school start times. However, even with the same start times, more students with online/synchronous instruction obtained sufficient sleep than in-person instruction. Significantly greater night-to-night variability in sleep-wake patterns was observed for students with in-person hybrid schedules versus students with online/synchronous + asynchronous schedules., Conclusions: These findings provide important insights regarding the association between instructional approach and school start times on the timing, amount, and variability of sleep in U.S. adolescents. Given the public health consequences of short and variable sleep in adolescents, results may be useful for education and health policy decision-making for post-pandemic secondary schools., (© Sleep Research Society 2021.

Background: The epidemiology of hospital adverse reactions (ARs), particularly allergic reactions, or hypersensitivity reactions (HSRs), is poorly defined. To determine priorities for allergy safety in healthcare, we identified and described safety reports of allergic reactions., Methods: We searched the safety report database of a large academic medical center from April 2006 to March 2016 using 101 complete, truncated, and/or misspelled key words related to allergic symptoms, treatments, and culprits (e.g., medications, foods). Patient and event data were summarized for ARs and two types of ARs, HSRs and side effects/toxicities., Results: Among 9111 key word search-identified events, 876 (10%) were ARs, of which 436 (5%) were HSRs and the remaining 440 (5%) were side effect reactions or toxicities. Whereas the most common HSRs were simple cutaneous reactions (83%), the following severe immediate HSRs were also identified: shortness of breath (16%), anaphylaxis (14%), and angioedema (12%). Most HSRs were caused by drugs (81%), with antibiotics (26%), particularly β-lactams (11%), and vancomycin (8%), commonly implicated. Other causes of drug HSRs included contrast agents (24%), chemotherapeutics (7%), and opioids (6%). Nondrug HSRs were from blood products (8%), latex (3%), and devices (3%). Food reactions were rarely identified (1%)., Conclusions: We identified ARs, HSRs, and side effects/toxicities, contained in a decade of safety reports at an academic medical center. Allergy safety in the healthcare setting should target approaches to common and severe reactions, with a focus on the safe administration of β-lactams, vancomycin, contrast agents, chemotherapeutics, and opioids. Priority nondrug HSR culprits include blood products, latex, and devices., Competing Interests: The authors disclose no conflict of interest., (Copyright © 2019 Wolters Kluwer Health, Inc.

The COVID-19 pandemic has brought unprecedented levels of stress to individuals in the U.S. and throughout the world. These high stress levels place individuals at risk for symptoms of anxiety, depression, and other psychiatric disorders. The current study applies a control-based model of coping to contribute to the development of evidence-based interventions to promote resilience. Data were collected online from April 22 through July 12, 2020. Data from two samples of U. S. community adults who completed an online battery of standardized questionnaires were combined (N = 709). More than a quarter reported moderate to severe levels of depression symptoms, and more than one-fifth reported moderate to severe levels of anxiety symptoms; symptom levels were higher among adults who reported more COVID-19-related stress. As hypothesized, multiple regression analyses indicated that greater use of primary and secondary control coping was associated with lower symptom levels, whereas greater use of disengagement coping was associated with higher symptom levels, above and beyond the association of stress with symptoms. Race and ethnicity emerged as important moderators of these associations, indicating that what constitutes adaptive coping varies according to characteristics of the individual. Implications for public health policy and clinical practice are discussed., Supplementary Information: The online version contains supplementary material available at 10.1007/s12144-021-02444-6., Competing Interests: Conflict of InterestNone., (© The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2021.)

Objectives: To assess changes in sleep parameters and circadian rhythm metrics measured by actigraphy in preschool-aged children., Design: Longitudinal analysis over 1 year., Participants: Ninety-four children living in Tijuana and Ensenada, Mexico., Measurements: Children wore accelerometers on the right hip for one continuous week at baseline and 1-year follow-up. Parents recorded child bedtime, waketime, and naps in sleep diaries. We used cosinor and nonparametric approaches to calculate circadian rhythm metrics., Results: At baseline, children had a mean age of 4.2 years, and 51.1% were girls. In multivariable models adjusted for age, gender, BMI category, parental education, household income and city, at follow-up children had significantly earlier waketimes (β = -7.99 minutes, p < .001) compared to baseline. Children also had lower sleep onset latency (β = -2.32 minutes, p = .057), and longer nighttime sleep (β = 9.38 minutes, p = .079), but these changes were not significant at the α < 0.05 level. We found significant increases in log relative amplitude (β = 0.017, p = .009), and decreases in log midline estimated statistic of rhythm (β = -0.084, p = .017) and log of the least active 5-hour period (β = -0.057, p = .010). When we adjusted for co-sleeping, we found significant decreases in the number of nighttime awakenings (β = -1.29, p = .011) but otherwise similar results. There were no other changes in sleep parameters or circadian rhythm metrics., Conclusions: Mean increases in nighttime sleep and earlier wake times over one year were concomitant with decreases in overall activity levels and increases in circadian rhythm robustness. Co-sleeping was a predictor of sleep disturbances. This study provides longitudinal evidence regarding changes in sleep and circadian metrics in a sample of children from an under-researched sociodemographic group during an important, early life period., (Copyright © 2021 National Sleep Foundation.

Background: The Centers for Disease Control and Prevention state that a severe or immediate allergic reaction to the first dose of an mRNA COVID-19 vaccine is a contraindication for the second dose., Objective: To assess outcomes associated with excipient skin testing after a reported allergic reaction to the first dose of mRNA COVID-19 vaccine., Methods: We identified a consecutive sample of patients with reported allergic reactions after the first dose of mRNA COVID-19 vaccine who underwent allergy assessment with skin testing to polyethylene glycol (PEG) and, when appropriate, polysorbate 80. Skin testing results in conjunction with clinical phenotyping of the first-dose mRNA COVID-19 vaccine reaction guided second-dose vaccination recommendation. Second-dose mRNA COVID-19 vaccine reactions were assessed., Results: Eighty patients with reported first-dose mRNA COVID-19 vaccine allergic reactions (n = 65; 81% immediate onset) underwent excipient skin testing. Of those, 14 (18%) had positive skin tests to PEG (n = 5) and/or polysorbate 80 (n = 12). Skin testing result did not affect tolerance of the second dose in patients with immediate or delayed reactions. Of the 70 patients who received the second mRNA COVID-19 vaccine dose (88%), 62 had either no reaction or a mild reaction managed with antihistamines (89%), but 2 patients required epinephrine treatment. Three patients with positive PEG-3350 intradermal (methylprednisolone) testing tolerated second-dose mRNA COVID-19 vaccination. Refresh Tears caused nonspecific skin irritation., Conclusions: Most individuals with a reported allergic reaction to the first dose of mRNA COVID-19 vaccines, regardless of skin test result, received the second dose safely. More data are needed on the value of skin prick testing to PEG (MiraLAX) in evaluating patients with mRNA COVID-19 vaccine anaphylaxis. Refresh Tears should not be used for skin testing., (Copyright © 2021 American Academy of Allergy, Asthma & Immunology. Published by Elsevier Inc. All rights reserved.)

Objectives: The COVID-19 virus has resulted not only in high rates of morbidity and mortality across the globe, but in widespread mental health problems and sleep disruption, likely as a result of pandemic-related stressors. The current study examines associations among COVID-related stress, sleep quality, and mental health., Design: Cross-sectional data were collected via online surveys in May 2020., Participants: were 2541 community adults ages 18-70 from Israel (N = 1969) and the U.S. (N = 572)., Measurement: Participants completed measures of COVID-related stress, sleep quality, and symptoms of anxiety, depression and adjustment disorder., Results: Participants reported high rates of depression and anxiety symptoms, adjustment difficulties, and poor sleep quality. In both countries, COVID-related stressors were associated with both anxiety and depression, and these associations were mediated by sleep disturbances., Conclusions: These results support the role of sleep in mental health difficulties. Widespread, accessible, evidence-based interventions are urgently needed to improve health and mental health and to promote resilience in preparation for future global crises., (Copyright © 2021.

The U.S. Food and Drug Administration (FDA) has recently issued an Emergency Use Authorization (EUA) for 2 highly effective coronavirus disease 2019 (COVID-19) vaccines from Pfizer-BioNTech and Moderna. This has brought hope to millions of Americans in the midst of an ongoing global pandemic. The FDA EUA guidance for both vaccines is to not administer the vaccine to individuals with a known history of a severe allergic reaction (eg, anaphylaxis) to any component of the COVID-19 vaccine. The Centers for Disease Control and Prevention (CDC) additionally advises individuals with a history of an immediate allergic reaction to a vaccine or injectable or any history of anaphylaxis be observed for 30 minutes after COVID-19 vaccination. All other individuals should be observed for 15 minutes after COVID-19 vaccination. Staff at vaccine clinics must be able to identify and manage anaphylaxis. Post-FDA EUA, despite very strong safety signals in both phase 3 trials, reports of possible allergic reactions have raised public concern. To provide reassurance and support during widespread global vaccination, allergists must offer clear guidance to individuals based on the best information available, but also in accordance with the broader recommendations of regulatory agencies. This review summarizes vaccine allergy epidemiology and proposes drug and vaccine allergy expert opinion informed risk stratification for Allergy specialist use in conjunction with guidance of public health and regulatory authorities. The risk stratification schema guide care for (1) individuals with different allergy histories to safely receive their first mRNA COVID-19 vaccine and (2) individuals who develop a reaction to their first dose of mRNA COVID-19 vaccine., (Copyright © 2020 American Academy of Allergy, Asthma & Immunology.

Background: Penicillin and other beta-lactam antibiotics are recommended for group B Streptococcus and cesarean section prophylaxis, but approximately 10% of pregnant patients report a penicillin allergy., Objective: To assess the safety and impact of penicillin allergy evaluation in pregnant patients., Methods: In this retrospective study of obstetrician-ordered Allergy/Immunology (AI) electronic consultations (e-consults) from September 20, 2017 through December 31, 2019, we reviewed the electronic health record for e-consult recommendation; patient demographic, obstetric, and allergy histories; and peripartum antibiotic utilization with indication. For patients whose electronic consultation recommended an in-person AI evaluation, testing outcomes were determined, and multivariable logistic regression models were used to compare antibiotic use between patients who did and did not receive an in-person AI evaluation., Results: Of 389 obstetrician-ordered e-consults, 363 (93%) recommended an in-person AI evaluation; of these, 222 (61%) patients received an in-person AI evaluation. Of 220 (99%) patients skin tested, 209 (95%) had their penicillin allergy label safely removed. Compared with patients who did not receive an in-person AI evaluation despite it being recommended (n = 141), patients with in-person AI evaluation (n = 222) had reduced peripartum vancomycin (adjusted odds ratio [aOR], 0.07; 95% CI, 0.01-0.33), clindamycin (aOR, 0.17; 95% CI, 0.08-0.34), and gentamicin (aOR, 0.39; 95% CI, 0.19-0.78) use and increased penicillin (aOR, 18.0; 95% CI, 6.30-51.2) use. The fully AI evaluated patients had increased first-line antibiotic prophylaxis for group B Streptococcus (aOR, 26.9; 95% CI, 6.32-114) and cesarean section (aOR, 1.94; 95% CI, 1.06-3.52)., Conclusions: In a sample of 220 pregnant patients with penicillin allergy histories and in-person AI evaluation, penicillin allergy testing was safe and associated with significantly reduced broad-spectrum antibiotic use and increased first-line beta-lactam antibiotic use., (Copyright © 2020 American Academy of Allergy, Asthma & Immunology.

Immediate hypersensitivity to drugs is characterized by symptoms such as hives, swelling, and wheezing. To prevent a negative impact on care, assessment by an allergist is important. Evaluation requires a clear clinical history, but it is often lacking or vague, which makes a diagnosis difficult. Allergists instead can use skin testing and drug challenge to evaluate drug hypersensitivity reactions, which help the patient and provider understand the causative drug(s) and, more importantly, enables the use of the exonerated drug(s). Although penicillin skin testing is standardized, well described, and widely used, skin testing for most other drugs requires the use of a nonirritating skin testing concentration that can have a low negative predictive value. Drug challenges are the criterion standard for confirming tolerance. The allergist must obtain an in-depth clinical history and then follow with skin testing and/or drug challenges when indicated to determine which drugs can be de-labelled and which should be avoided. In this review, we focused on the evaluation of drug hypersensitivity reactions to antibiotics, perioperative agents, biologics, and chemotherapeutics.

Background: Facilitating beta-lactam antibiotic use in patients reporting beta-lactam allergies in acute care settings is important to individual patient outcomes and public health; however, few initiatives have targeted the Emergency Department (ED) setting., Methods: We implemented pathways for patients reporting prior penicillin and/or cephalosporin hypersensitivity as part of a hospital guideline in the ED of a large academic medical center in the United States. We described beta-lactam test doses, pathway compliance, hypersensitivity reactions (HSRs), and allergy record updating associated with ED-administered beta-lactam test doses from October 2016 to June 2018., Results: 310 beta-lactam antibiotic test doses were administered to patients with penicillin and/or cephalosporin allergy histories in the study period (average volume 15/month [standard deviation 4]). Test doses were to cephalosporins (85%), penicillins (12%), and carbapenems (4%). 219 (71%) of test doses were compliant with the pathways. Ten patients (3.2%; 95% CI 1.6%-5.9%) had HSRs; five HSR patients (50%) had beta-lactams administered that were not pathway compliant. The allergy record was updated in 146 (47%) of patients, with improvement over the study period (p < 0.001)., Conclusions: Inpatient approaches to prescribing beta-lactams in patients reporting beta-lactam allergies can be operationalized in the ED. Additional efforts are required to ensure guideline compliance and appropriate allergy documentation., (© 2019 The Author(s).)

Background: Allergic condition management more often requires allergist guidance than allergy testing; necessary testing may be unavailable at initial drug allergy consultations. Electronic consultations (e-consults) provide expedited, problem-focused, potentially cost-saving care in other medical specialties, but have not yet been studied in Allergy/Immunology., Objective: To describe e-consult use at an academic allergy/immunology practice., Methods: E-consult data (August 10, 2016 through July 31, 2018) and in-person consult data (August 1, 2014 through July 31, 2018) were reviewed to determine consult volume, outcomes, indications, and timing. Referral reasons and wait times were compared with chi-square tests., Results: E-consults grew from 1% to 10% of all new consults, with concurrent growth in in-person consults. Of 306 completed e-consults, 41 (13.4%) made diagnostic, therapeutic, or alternative referral recommendations, with 30 (73%) recommendations followed; 183 (59.8%) patients required an in-person Allergy/Immunology consult, and only 5 (<2%) patients saw an allergist without an e-consult recommendation to do so. E-consults were used more often than in-person consults for adverse drug reactions (66% vs 9%; P < .001), especially penicillin allergy (132, 61% of all e-consults) and immunodeficiency (15% vs 2%; P < .001). Allergists completed e-consults in a median of 11 minutes, with a median turnaround time of 22 hours. E-consult implementation was associated with a decreased median in-person consult wait time (1.5 fewer calendar days; P < .05)., Conclusions: E-consults were increasingly used, particularly for historical adverse drug reactions and immunodeficiency. Implementation of an e-consult program resulted in decreased in-person wait times despite an increase in overall consult volume, supporting this model's ability to provide expedited, problem-focused care., (Copyright © 2019 American Academy of Allergy, Asthma & Immunology.
