PubMed-indexed Research Productivity of Urology Applicants and Residents: Does Medical Student Research Productivity Predict Resident Research or Pursuit of an Academic Career?

OBJECTIVE: To assess the research output of urology residents at top programs and investigate the correlation between medical school research productivity (MRP), research during residency (RRP), and pursuit of academic practice. Further, to characterize trends in MRP before and after the transition to pass/fail scoring of USMLE Step 1. METHODS: Our team previously reported on the PubMed-indexed research productivity of applicants matching into top 50 urology programs. Here, we used the same list of residents, recorded their publications during residency, and noted their career paths, including fellowships, academic roles, or private practice. We then highlight the relationship between MRP, RRP, and pursuit of an academic career. We also highlight trends in MRP of applicants matching to top residency programs before and after the transition to pass/fail Step 1 exams. RESULTS: We collected data on 727 residents. On multivariate logistic regression, total medical school publications (OR 1.07, 95% CI 0.97, 1.19), total urology publications (OR 1.05, 95% CI 0.92, 1.21), and total first author publications (OR 1.10, 95% CI 0.91, 1.33) were not associated with academic appointment after residency. On the other hand, RRP was correlated with pursuit of academics (1.08, 95% 1.03,1.14). MRP was significantly higher amongst applicants who applied with a pass/fail exam compared to those who did not. CONCLUSION: MRP is not predictive of pursuing an academic career, but RRP is. There is a significant increase in average MRP of those matching to top urology programs after the transition to a pass/fail scoring system for Step 1.

A Tale of 102,726 Messages: Characterizing the Modern Urologist's Portal Message Burden After Common Urologic Surgeries.

INTRODUCTION: We aimed to characterize patient portal messaging use after urologic surgery to identify administrative burden and evaluate postoperative clinical associations. METHODS: Epic was queried for all urologic surgeries performed at the Mayo Clinic enterprise between 2019 and 2022. Data from the highest volume procedures were extracted including patient-generated portal messages to their provider and emergency department (ED) visits within 6 months of surgery. Factors associated with portal users and message volume, as well as the impact of portal use on risk of subsequent ED visit, were evaluated. RESULTS: We analyzed data from 23,621 urologic procedures, which generated 102,726 patient portal messages within 6 months of surgery. We found that 55% of our cohort sent at least 1 message. Stratifying by subspecialty, endourologic surgeries generated the fewest number of messages per surgery (3.83; SD, 8.76), whereas female pelvic medicine and reconstructive surgeries yielded the most (6.05; SD, 10.92). Younger age, female sex, and White race were associated with increased portal utilization. Multivariable time-to-event analysis revealed a 33% reduction in the risk of ED presentation within 90 days after surgery for patients using the patient portal compared with those who did not. CONCLUSIONS: While only half of patients sent portal messages after surgery, active users showed a 33% reduction in ED visits, suggesting its potential to reduce health care utilization. Encouraging broader portal adoption can improve outcomes. However, the message burden for urologists necessitates solutions. Resource allocation should prioritize strategies to help urologists manage messages while preserving the established clinical benefits.

The public health burden of parent-reported food allergy-related missed school days among US children.

Background: Food allergy (FA) is a common chronic condition among U.S. children. Children with FA and their families often report greater psychosocial burden, which is adversely impacted by the inability to participate in daily activities. Regularly attending school remains central to supporting the well-being of children with FAs and related academic success. Objective: The objective was to estimate the frequency of FA-related school absences, determine predictors, and understand how report of such absences is associated with FA-related psychosocial burden. Methods: A survey was administered to a nationally representative sample of U.S. households in 2015-2016, obtaining parent-proxy responses for 38,408 children. Prevalence estimates were based on responses from NORC's AmeriSpeak Panel (51% completion rate), which were augmented by nonprobability-based responses via calibration weighting to increase precision. Prevalence was estimated via weighted proportions. Multiple logistic regression models evaluated factors associated with FA-related missed school days. Results: Thirty-seven percent of children with FA who attended school in the past 12 months reportedly had one or more FA-related absence, with 13% missing 1-2 days (95% confidence interval [CI], 11.41-15.49 days), 17% missing 3-7 days (95% CI, 6.82-10.91 days), and 4% missing 8-14 days (95% CI, 3.13-6.20 days). Hispanic children were more likely to report missed school days in the past 12 months compared with white, non-Hispanic children with FA (odds ratio [OR] 1.62 [95% CI, 1.16-2.26]). Children with multiple FAs (OR 1.35 [95% CI, 1.03-1.76]), history of epinephrine use (OR 2.22 [95% CI, 1.70-2.90]), and anaphylaxis (OR 1.64 [95% CI, 1.26-2.14]) in the past 12 months, and those with a current epinephrine prescription (OR 1.05 [95% CI, 0.075-1.47]) have greater odds of reported FA-related school absence. Report of one or more FA-related absences was also associated with greater FA-related psychosocial burden (OR 1.72 [95% CI, 1.46-2.01]). Conclusion: Parent report of children missing school for reasons related to FA is remarkably common and associated with greater FA-related psychosocial burden.

Prompt matters: evaluation of large language model chatbot responses related to Peyronie's disease.

Introduction: Despite direct access to clinicians through the electronic health record, patients are increasingly turning to the internet for information related to their health, especially with sensitive urologic conditions such as Peyronie's disease (PD). Large language model (LLM) chatbots are a form of artificial intelligence that rely on user prompts to mimic conversation, and they have shown remarkable capabilities. The conversational nature of these chatbots has the potential to answer patient questions related to PD; however, the accuracy, comprehensiveness, and readability of these LLMs related to PD remain unknown. Aims: To assess the quality and readability of information generated from 4 LLMs with searches related to PD; to see if users could improve responses; and to assess the accuracy, completeness, and readability of responses to artificial preoperative patient questions sent through the electronic health record prior to undergoing PD surgery. Methods: The National Institutes of Health's frequently asked questions related to PD were entered into 4 LLMs, unprompted and prompted. The responses were evaluated for overall quality by the previously validated DISCERN questionnaire. Accuracy and completeness of LLM responses to 11 presurgical patient messages were evaluated with previously accepted Likert scales. All evaluations were performed by 3 independent reviewers in October 2023, and all reviews were repeated in April 2024. Descriptive statistics and analysis were performed. Results: Without prompting, the quality of information was moderate across all LLMs but improved to high quality with prompting. LLMs were accurate and complete, with an average score of 5.5 of 6.0 (SD, 0.8) and 2.8 of 3.0 (SD, 0.4), respectively. The average Flesch-Kincaid reading level was grade 12.9 (SD, 2.1). Chatbots were unable to communicate at a grade 8 reading level when prompted, and their citations were appropriate only 42.5% of the time. Conclusion: LLMs may become a valuable tool for patient education for PD, but they currently rely on clinical context and appropriate prompting by humans to be useful. Unfortunately, their prerequisite reading level remains higher than that of the average patient, and their citations cannot be trusted. However, given their increasing uptake and accessibility, patients and physicians should be educated on how to interact with these LLMs to elicit the most appropriate responses. In the future, LLMs may reduce burnout by helping physicians respond to patient messages.

Differences in familiarity with oral immunotherapy among caregivers of White and Black children with food allergy.

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 χ2 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.

Health care resource use and costs in patients with food allergies: a United States insurance claims database analysis.

AIMS: Food allergies impose a large clinical and financial burden on patients and the health care system. However, little is known about the factors associated with health care resource use and costs. The aim of this study was to investigate health care resource use and costs in individuals with food allergies utilizing health care in the United States. METHODS: We conducted a retrospective analysis of insurance claims data from the Merative MarketScan Research Databases (indexed from 1 January 2015 to 30 June 2022). All-cause and food allergy-related health care resource use, direct medical, and out-of-pocket costs for medical services were estimated for 12 months post-index using International Classification of Diseases [ICD] codes. RESULTS: Of 355,520 individuals with food allergies continuously enrolled in a health insurance plan for ≥12 months pre- and post-index, 17% had a food allergy-related emergency department visit and 0.9% were hospitalized. The top patient characteristic associated with all-cause and food allergy-related hospitalizations, all-cause costs, and food allergy-related outpatient visit costs was a Charlson Comorbidity Index score of ≥2. Food allergy-related direct medical and out-of-pocket costs were high among patients with a food allergy-related visit. Out-of-pocket cost per patient per year for outpatient visits, emergency department visits, and hospitalizations had an estimated mean of $1631 for patients with food allergy-related visits, which is ∼11% of the total costs for these services ($14,395 per patient per year). LIMITATIONS: Study limitations are primarily related to the nature of claims databases, including generalizability and reliance on ICD codes. Nevertheless, MarketScan databases provide robust patient-level insights into health care resource use and costs from a large, commercially insured patient population. CONCLUSION: The health care resource use of patients with food allergies imposes a burden on both the health care system and on patients and their families, especially if patients had comorbidities.

Some people with food allergies might need extra visits to the doctor or hospital to manage allergic reactions to food, and these visits add to the cost of medical services for both families and for health care providers. Using records of health insurance claims, we looked into the factors affecting medical visits and costs in people with food allergies in the United States. For people with food allergies, having additional medical conditions (measured using the Charleson Comorbidity Index) were linked with extra medical visits and costs. Out-of-pocket costs were high for people who visited a doctor or hospital for their food allergies (costing each person more than $1,600 per year). The total medical cost of food allergy-related care was $14,395 per person per year, paid for by families and health care providers. Our findings might help to better manage and treat people with food allergies and reduce medical costs.

Awareness and Application of United States Food Allergy Prevention Guidelines Among Pediatricians and Other Clinicians.

OBJECTIVE: To characterize the awareness of, adherence to, and barriers to the 2017 National Institute of Allergy and Infectious Diseases (NIAID) peanut allergy prevention guidelines among the pediatrics health care workforce. STUDY DESIGN: Pediatricians, family physicians, advanced practice providers (APPs), and dermatologists who provide care for infants were solicited for a population-based online survey, administered from June 6, 2022, through July 3, 2022. The survey collected information about NIAID guideline awareness, implementation, and barriers as well as concerns related to the guidelines. RESULTS: A total of 250 pediatricians, 250 family physicians, 504 APPs, and 253 dermatologists met inclusion criteria. Self-reported guideline awareness was significantly higher for pediatricians (76%) compared with dermatologists (58%), family physicians (52%), and APPs (45%) (P < .05). Among participants who were aware of the guidelines, most reported using part or all of the guidelines in their clinical practices. Reported practice patterns for peanut introduction in 6-month-old infants were variable and did not always align with guidelines, particularly for infants with mild-to-moderate atopic dermatitis. CONCLUSIONS: Although pediatricians have the highest self-reported level of NIAID guideline awareness, awareness was suboptimal irrespective of provider type. Education for all pediatric clinicians is urgently needed to promote evidence-based peanut allergy prevention practices.

Understanding the burden of food allergy among urban and rural school children from north India.

Background: There is paucity of reliable epidemiological data regarding the burden of food allergy in most developing countries, including India. Objective: To provide current estimates of the prevalence and distribution of food allergy among urban and rural school children aged 6-14 years in Delhi and the National Capital Region (NCR) of Khekra in India. Methods: A cross-sectional study was conducted from January 2022 to February 2023 to enroll school children, 6-14 years, from select urban and rural schools in Delhi and NCR. A questionnaire consisting of questions focused on household environment, early life factors, and pediatric food allergy characteristics was administered by a trained medical researcher to collect parent-proxy data. Univariate statistics were used to describe frequencies, percentages, and 95% confidence intervals for survey items. Results: The estimated prevalence of parent-reported food allergy was 0.8% (95% CI: 0.4-1.5; urban: 0.4%, 95% CI: 0.1-1.1; rural: 1.7%, 95% CI: 0.7-3.5). Fruits such as mango (0.3%, 95% CI: 0.1-0.9), strawberry (0.1%, 95% CI: 0.0-0.7), orange (0.1%, 95% CI: 0.0-0.7), and custard apple (0.1%, 95% CI: 0.0-0.7) were reported only by urban children, while rural children reported yogurt (0.6%, 95% CI: 0.1-1.8) and wheat (0.3%, 95% CI: 0.0-1.3). Both groups reported brinjal (also known as eggplant) and banana, 0.1% (95% CI: 0.0-0.7) of urban and 0.3% (95% CI: 0.0-1.3) of rural, respectively. Overall, commonly reported clinical symptoms were diarrhea and/or vomiting (100%, 95% CI: 76.2-100), abdominal pain (88.9%, 95% CI: 58.6-98.8), and rash/itchy skin (66.7%, 95% CI: 34.8-89.6). Among children with parent reported food allergy, 66.7% (95% CI: 34.8-89.6) of food allergies were physician diagnosed, of which 33.3% were diagnosed via history alone (95% CI:7.7-71.4) while 66.7% (95% CI: 28.6-92.3) were confirmed via skin prick test and/or blood test. Conclusion: The overall prevalence of food allergy is very low in Delhi and Khekra, India. Future work should focus on elucidating the complex interplay of early-life, environmental, genetic, and lifestyle factors to understand the reasons for India's low food allergy burden and improve epidemiological clues to prevention for the nations with higher disease burden.

Germline Pathogenic Variants Identified in Patients With Genitourinary Malignancies Undergoing Universal Testing: A Multisite Single-Institution Prospective Study.

PURPOSE: This study aimed to investigate the prevalence of pathogenic germline variants (PGVs) in hereditary cancer genes utilizing a universal testing approach and to determine the rate of PGVs that would have been missed based on National Comprehensive Cancer Network (NCCN) guidelines in genitourinary (GU) malignancies. MATERIALS AND METHODS: A multisite, single-institution prospective germline genetic test (GGT) was universally offered to patients with new or active diagnoses of GU malignancies (prostate, bladder, and renal) from April 2018 to March 2020 at Mayo Clinic sites. Participants were offered GGT using a next-generation sequencing panel of > 80 genes. Demographic, tumor characteristics, and genetic results were evaluated. NCCN GU cancer guidelines were used to identify whether patients had incremental findings, defined as PGV-positive patients who would not have received testing based on NCCN guidelines. RESULTS: Of 3095 individuals enrolled in the study, 601 patients had GU cancer (prostate = 358, bladder = 106, and renal = 137). The mean enrollment age was 67 years (SD 9.1), 89% were male, and 86% of patients were non-Hispanic White. PGVs were identified in 82 (14%) of all GU patients. PGV prevalence breakdown by cancer type was: 14% prostate, 14% bladder, and 13% renal cancer. Nearly one-third of identified PGVs were high penetrance, and the majority of these (67%) were clinically actionable. Incremental PGVs were identified in 28 (57%) prostate, 15 (100%) bladder, and 14 (78%) renal cancer patients. Of the 82 patients with PGV findings, 29 (35%) had at least 1 relative undergo cascade testing for the familial variant(s) identified. CONCLUSIONS: More than 1 in 8 patients with GU malignancies were found to carry a PGV, with 67% of patients with high-penetrance PGVs undergoing clinically actionable changes. The majority of these PGVs would not have been identified based on current testing criteria. These findings support universal GGT for GU malignancies and underscore its potential to enhance risk assessment and guide precision interventions in urologic oncology.

Quantification of mechanical behavior of rat tail under compression.

BACKGORUND: The development of vibration-induced finger disorders is likely associated with combined static and dynamic responses of the fingers to vibration exposure. To study the mechanism of the disorders, a new rat-tail model has been established to mimic the finger vibration and pressure exposures. However, the mechanical behavior of the tail during compression needs to be better understood to improve the model and its applications. OBJECTIVE: To investigate the static and time-dependent force responses of the rat tail during compression. METHODS: Compression tests were conducted on Sprague-Dawley cadaver rat tails using a micromechanical system at three deformation velocities and three deformation magnitudes. Contact-width and the time-histories of force and deformation were measured. Additionally, force-relaxation tests were conducted and a Prony series was used to model the force-relaxation behavior of the tail. RESULTS: The rat tails' force-deformation and stiffness-deformation relationships were strongly nonlinear and time-dependent. Force/stiffness increased with an increase in deformation and deformation velocity. The time-dependent force-relaxation characteristics of the tails can be well described using a Prony series. CONCULSIONS: We successfully quantified the static and time-dependent force responses of rat tails under compression. The identified mechanical behavior of the tail can help improve the rat-tail model and its applications.

Patient-Reported Outcome Measures in Food and Drug Allergy.

A patient-reported outcome is directly reported by the patient without interpretation of the patient's response by anyone else. It refers to the patient's health (symptoms and feelings), quality of life, or functional status associated with health care or treatment. Patient-reported outcome measures (PROMs) are defined as the tools or instruments that are used to measure patient-reported outcomes. Health-related quality of life has been the most studied psychosocial PROM in food allergy, using validated questionnaires. In drug allergy, PROMs are useful in capturing patients' experiences of potential allergic reactions, including subjective symptoms such as headache, dizziness, or fatigue. Patient-reported outcome measures can also help differentiate true allergies from side effects or other nonallergic reactions and inform decisions about drug challenges and de-labeling strategies. Ensuring the chosen tool is validated for the specific allergy context is crucial for accurate data collection. Integrating patient-reported experiences alongside traditional methods can lead to more accurate assessments and personalized care.

Sociodemographic inequities in food allergy: Insights on food allergy from birth cohorts.

A large and growing corpus of epidemiologic studies suggests that the population-level burden of pediatric FA is not equitably distributed across major sociodemographic groups, including race, ethnicity, household income, parental educational attainment, and sex. As is the case for more extensively studied allergic disease states such as asthma and atopic dermatitis epidemiologic data suggest that FA may be more prevalent among certain populations experiencing lower socioeconomic status (SES), particularly those with specific racial and ethnic minority backgrounds living in highly urbanized regions. Emerging data also indicate that these patients may also experience more severe FA-related physical health, psychosocial, and economic outcomes relating to chronic disease management. However, many studies that have identified sociodemographic inequities in FA burden are limited by cross-sectional designs that are subject to numerous biases. Compared with cross-sectional study designs or cohorts established later in life, birth cohorts offer advantages relative to other study designs when investigators seek to understand causal relationships between exposures occurring during the prenatal or postnatal period and the atopic disease status of individuals later in life. Numerous birth cohorts have been established across recent decades, which include evaluation of food allergy-related outcomes, and a subset of these also have measured sociodemographic variables that, together, have the potential to shed light on the existence and possible etiology of sociodemographic inequities in food allergy. This manuscript reports the findings of a comprehensive survey of the current state of this birth cohort literature and draws insights into what is currently known, and what further information can potentially be gleaned from thoughtful examination and further follow-up of ongoing birth cohorts across the globe.

The mental health burden of food allergies: Insights from patients and their caregivers from the Food Allergy Research & Education (FARE) Patient Registry.

Background: Food allergies impose a large psychosocial burden, including mental, emotional, and social aspects, on both patients and their caregivers. Patients, caregivers, and their families often experience anxiety, isolation, and fear around food allergies. Objective: To assess the real-world mental health burden of food allergies, using the Food Allergy Research & Education (FARE) Patient Registry (NCT04653324). Methods: Self-reported data from patients with food allergies, and their caregivers, were analyzed from the FARE Food Allergy History and Mental Health Concerns surveys. Odds ratios were also calculated as a measure of association between patient food allergy characteristics and the likelihood of having mental health concerns or a formal mental health diagnosis. Results: The FARE Patient Registry included 1680 patients/caregivers. Anxiety (54%) and panic (32%) were the most common emotions that patients reported as a result of eating the food that produced an allergic reaction. About two-thirds of patients reported mental health concerns related to food allergies (62%), including anxiety after an allergic reaction, anxiety about living with food allergies, and concerns about food avoidance. Caregivers also experienced fear for the safety of their children, and often sought mental health care to cope with worry related to caring for patients with food allergies. The likelihood of having food allergy-related mental health concerns was increased for patients experiencing more than 1 reaction per year (OR 1.68-1.90) and was lowered for patients having a formal mental health diagnosis (OR 0.43). Caregivers filling out the FARE survey for pediatric patients (OR 4.03) and experiencing food allergy-related mental health concerns (OR 2.36) were both significant predictors for having a formal mental health diagnosis. Conclusion: Our study highlights a continuing unmet need for mental health screening and support as part of the management of patients with food allergies.

Glutamylation of Npm2 and Nap1 acidic disordered regions increases DNA mimicry and histone chaperone efficiency.

Histone chaperones-structurally diverse, non-catalytic proteins enriched with acidic intrinsically disordered regions (IDRs)-protect histones from spurious nucleic acid interactions and guide their deposition into and out of nucleosomes. Despite their conservation and ubiquity, the function of the chaperone acidic IDRs remains unclear. Here, we show that the Xenopus laevis Npm2 and Nap1 acidic IDRs are substrates for TTLL4 (Tubulin Tyrosine Ligase Like 4)-catalyzed post-translational glutamate-glutamylation. We demonstrate that to bind, stabilize, and deposit histones into nucleosomes, chaperone acidic IDRs function as DNA mimetics. Our biochemical, computational, and biophysical studies reveal that glutamylation of these chaperone polyelectrolyte acidic stretches functions to enhance DNA electrostatic mimicry, promoting the binding and stabilization of H2A/H2B heterodimers and facilitating nucleosome assembly. This discovery provides insights into both the previously unclear function of the acidic IDRs and the regulatory role of post-translational modifications in chromatin dynamics.

The clinical burden of food allergies: Insights from the Food Allergy Research & Education (FARE) Patient Registry.

Background: Food allergies are serious and potentially life-threatening, and often place a large burden on patients and their caregivers, including impacts on quality of life. Objective: To assess the real-world patient burden of food allergies, using self-reported data available from the Food Allergy Research & Education (FARE) Patient Registry (NCT04653324). Methods: The FARE Patient Registry is voluntary and captures real-world experiences of adults and pediatric patients in the United States, and their caregivers, through a series of surveys assessing patient health and experiences with food allergies. Self-reported data were descriptively analyzed. Results: The FARE study cohort included 5587 patients with food allergies; 82% had multiple food allergies and 62% were aged <18 years. About half of the patients were first diagnosed by an allergist/immunologist (53%), most commonly with a skin prick test (71%) or a serum immunoglobulin E test (62%). This analysis found that food allergies (most commonly peanut [66%], tree nuts [61%], egg [43%], and milk [37%]) impart a large clinical burden on patients, many of whom experience food-related allergic reactions and comorbidities. Many patients experienced >1 food-related allergic reaction per year (42%), with 46% experiencing food-induced anaphylaxis. Half of all food-related allergic reactions occurred at home. Accidental exposures to food allergens were experienced by 77% of patients. The most common allergic comorbidities reported by patients with food allergies were atopic dermatitis (48%), asthma (46%), and allergic rhinitis (39%). The clinical burden of food allergies were found to be greater in patients with multiple food allergies, and different for adults versus pediatric patients. Conclusion: This is the first study to assess patient experience and disease burden information from patients contributing to the FARE Patient Registry, thus providing a unique insight into the lives of patients in the United States with food allergies. These insights may assist clinicians and other public health stakeholders in the management of patients with food allergies.

The electron density: a fidelity witness for quantum computation.

There is currently no combination of quantum hardware and algorithms that can provide an advantage over conventional calculations of molecules or materials. However, if or when such a point is reached, new strategies will be needed to verify predictions made using quantum devices. We propose that the electron density, obtained through experimental or computational means, can serve as a robust benchmark for validating the accuracy of quantum computation of chemistry. An initial exploration into topological features of electron densities, facilitated by quantum computation, is presented here as a proof of concept. Additionally, we examine the effects of constraining and symmetrizing measured one-particle reduced density matrices on noise-driven errors in the electron density distribution. We emphasize the potential benefits and future need for high-quality electron densities derived from diffraction experiments for validating classically intractable quantum computations of materials.

Epidemiology and the Growing Epidemic of Food Allergy in Children and Adults Across the Globe.

PURPOSE OF REVIEW: Food allergies are immune-mediated, complex disorders, which are the source of increasing health concern worldwide. The goal of this review is to present an updated summary of the food allergy (FA) burden among children and adults across different populations, focusing on research from the past 5 years. RECENT FINDINGS: FAs impact a growing number of global residents-particularly those residing in higher-income, industrialized regions. Moreover, growing epidemiologic evidence suggests that the population health burden of non-IgE-mediated FAs, such as food protein-induced enterocolitis syndrome, may also be higher than previously reported. FA is a complex trait that impacts infants, children, as well as adults across the globe. The population health burden of both IgE- and non-IgE-mediated FAs is likely to grow in the absence of rapid advances and widespread implementation of effective FA prevention and treatment interventions. Systematic epidemiological research initiatives are needed, both nationally and globally, to better understand and reduce the burden of these allergic diseases.

Food Allergy Reaction Severity and Management in a Diverse Population.

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.

Reported food-related symptoms and food allergen sensitization in a selected adult population in Hyderabad, India: A hospital-based survey.

Background: Research on reported food-related triggers of atopic disease in South Asian adults is lacking despite the region's large population and the global significance of allergic diseases. Objectives: The study aimed to identify prevalent local food items and assess allergic sensitization rates to potential trigger foods for atopic diseases via skin prick and specific IgE testing. Methods: The study began with a pilot survey of 100 subjects recruited from 4 hospitals in Hyderabad, India, focusing on foods perceived to relate to asthma, allergic rhinitis, atopic dermatitis, urticaria, and gastrointestinal allergic symptoms. A subsequent main study evaluated 2010 participants, 1754 of whom were diagnosed with an aforementioned atopic disease and who reported allergic symptoms related to any of 77 foods identified in the pilot study. Ultimately 1622 patients who consented to skin prick and specific IgE testing and who reported at least 1 food item triggering allergic diseases were included in the final analysis. Results: Among 1622 patients (average age, 42.6 ± 12.9 years; 55.5% male), asthma was the most commonly diagnosed atopic disease (26.4%), with itching and rash being frequently reported symptoms (22.7%). Notably, 94.9% of patients had total serum IgE > 144 kU/L. Chickpea, cabbage, eggplant, walnut, cumin, and betel leaf were the most commonly reported trigger foods. Conclusion: In this sample of South Indian adults diagnosed with allergic disease, reported food triggers were most commonly local dietary staples, while reported reactions to priority allergens like peanut and sesame were conspicuously absent. Observed concordance between patient-reported food triggers and sensitization to reported food triggers was low, highlighting the need for improved clinical evaluation of suspected triggers.
