Targeted learning with an undersmoothed LASSO propensity score model for large-scale covariate adjustment in health-care database studies.

Least absolute shrinkage and selection operator (LASSO) regression is widely used for large-scale propensity score (PS) estimation in health-care database studies. In these settings, previous work has shown that undersmoothing (overfitting) LASSO PS models can improve confounding control, but it can also cause problems of nonoverlap in covariate distributions. It remains unclear how to select the degree of undersmoothing when fitting large-scale LASSO PS models to improve confounding control while avoiding issues that can result from reduced covariate overlap. Here, we used simulations to evaluate the performance of using collaborative-controlled targeted learning to data-adaptively select the degree of undersmoothing when fitting large-scale PS models within both singly and doubly robust frameworks to reduce bias in causal estimators. Simulations showed that collaborative learning can data-adaptively select the degree of undersmoothing to reduce bias in estimated treatment effects. Results further showed that when fitting undersmoothed LASSO PS models, the use of cross-fitting was important for avoiding nonoverlap in covariate distributions and reducing bias in causal estimates.

Rationale and design of CHD PULSE: Congenital Heart Disease Project to Understand Lifelong Survivor Experience.

BACKGROUND: With improved survival of adults with congenital heart disease (CHD) comes a need to understand the lifelong outcomes of this population. The aim of this paper is to describe the rationale and design of Congenital Heart Disease Project to Understand Lifelong Survivor Experience (CHD PULSE), a study to determine long-term medical, neurocognitive, and psychosocial outcomes among adults with a history of intervention for CHD and to identify factors associated with those outcomes. METHODS: CHD PULSE is a cross-sectional survey conducted from September 2021 to April 2023 among adults aged 18 and older with a history of at least 1 intervention for CHD at 1 of 11 participating U.S. centers in the Pediatric Cardiac Care Consortium. Participants with CHD were asked to complete a 99-question survey on a variety of topics including: demographics, surgeries, health insurance, health care, heart doctors, general health, height and weight, education and work history, reproductive health (for women only), and COVID-19. To construct a control group for the study, siblings of survey respondents were invited to complete a similar survey. Descriptive statistics for demographics, disease severity, center, and method of survey completion were computed for participants and controls. Comparisons were made between participants and non-participants to assess for response bias and between CHD participants and sibling controls to assess for baseline differences. RESULTS: Among the 14,322 eligible participants, there were 3,133 respondents (21.9%) from 48 U.S. states with surveys returned for inclusion in the study. Sibling contact information was provided by 691 respondents, with surveys returned by 326 siblings (47.2%). The median age of participants was 32.8 years at time of survey completion, with an interquartile range of 27.2 years to 39.7 years and an overall range of 20.1 to 82.9 years. Participants were predominantly female (55.1%) and of non-Hispanic White race/ethnicity (87.1%). There were no differences between participants and non-participants regarding severity of CHD. Compared to nonparticipants, participants were more likely to be female, of older age, and be of non-Hispanic White race/ethnicity. Enrolled siblings were more likely to be female and slightly younger than participants. CONCLUSIONS: With surveys from 3,133 participants from across the U.S., CHD PULSE is poised to provide keen insights into the lifelong journey of those living with CHD, extending beyond mere survival. These insights will offer opportunities for informing strategies to enhance and improve future outcomes for this population of patients.

Breastfeeding by Disability Status in the United States: Pregnancy Risk Assessment Monitoring System, 2018-2020.

Objectives. To describe breastfeeding initiation and breastfeeding at 1, 2, and 3 months, and information sources on breastfeeding among women with a recent live birth by disability status. Methods. We analyzed October 2018 to December 2020 data from the Pregnancy Risk Assessment Monitoring System for 24 sites in the United States that included the Washington Group Short Set of Questions on Disability (seeing, hearing, walking or climbing stairs, remembering or concentrating, self-care, communicating). We defined disability as reporting "a lot of difficulty" or "cannot do this at all" on any of these questions. Results. Among 39 673 respondents, 6.0% reported disability. In adjusted analyses, breastfeeding was lower among respondents with disability at 2 (62.6% vs 66.6%; adjusted prevalence ratio [APR] = 0.94; 95% confidence interval [CI] = 0.89, 0.99) and 3 months (54.7% vs 59.6%; APR = 0.92; 95% CI = 0.86, 0.98) than those without disability. Respondents with disability were less likely to receive information from health care providers or support professionals (89.3% vs 92.3%), but as likely from breastfeeding or lactation specialists (78.1% vs 75.3%). Conclusions. Strategies to ensure women with disability, receive breastfeeding support, including breastfeeding information, could improve breastfeeding outcomes.

A protein functionalization platform based on selective reactions at methionine residues.

Nature has a remarkable ability to carry out site-selective post-translational modification of proteins, therefore enabling a marked increase in their functional diversity1. Inspired by this, chemical tools have been developed for the synthetic manipulation of protein structure and function, and have become essential to the continued advancement of chemical biology, molecular biology and medicine. However, the number of chemical transformations that are suitable for effective protein functionalization is limited, because the stringent demands inherent to biological systems preclude the applicability of many potential processes2. These chemical transformations often need to be selective at a single site on a protein, proceed with very fast reaction rates, operate under biologically ambient conditions and should provide homogeneous products with near-perfect conversion2-7. Although many bioconjugation methods exist at cysteine, lysine and tyrosine, a method targeting a less-explored amino acid would considerably expand the protein functionalization toolbox. Here we report the development of a multifaceted approach to protein functionalization based on chemoselective labelling at methionine residues. By exploiting the electrophilic reactivity of a bespoke hypervalent iodine reagent, the S-Me group in the side chain of methionine can be targeted. The bioconjugation reaction is fast, selective, operates at low-micromolar concentrations and is complementary to existing bioconjugation strategies. Moreover, it produces a protein conjugate that is itself a high-energy intermediate with reactive properties and can serve as a platform for the development of secondary, visible-light-mediated bioorthogonal protein functionalization processes. The merger of these approaches provides a versatile platform for the development of distinct transformations that deliver information-rich protein conjugates directly from the native biomacromolecules.

Dexmedetomidine Withdrawal Syndrome in Children in the PICU: Systematic Review and Meta-Analysis.

OBJECTIVES: To systematically review literature describing the clinical presentation, risk factors, and treatment for dexmedetomidine withdrawal in the PICU (PROSPERO: CRD42022307178). DATA SOURCES: MEDLINE/PubMed, Cochrane, Web of Science, and Scopus databases were searched. STUDY SELECTION: Eligible studies were published from January 2000 to January 2022 and reported clinical data for patients younger than 21 years old following discontinuation of dexmedetomidine after greater than or equal to 24 hours of infusion. DATA EXTRACTION: Abstracts identified during an initial search were screened and data were manually abstracted after full-text review of eligible articles. The Newcastle-Ottawa Scale was used to assess study quality. Summary statistics were provided and Spearman rank correlation coefficient was used to identify relationships between covariates and withdrawal signs. A weighted prevalence for each withdrawal sign was generated using a random-effects model. DATA SYNTHESIS: Twenty-three studies (22 of which were retrospective cohort studies) containing 28 distinct cohorts were included. Median cumulative dexmedetomidine exposure by dose was 105.95 µg/kg (range, 30-232.7 µg/kg), median dexmedetomidine infusion duration was 131.75 hours (range, 20.5-525.6 hr). Weighted estimates for proportion (95% CI) of subjects experiencing withdrawal signs across all cohorts were: hypertension 0.34 (range, 0.0-0.92), tachycardia 0.26 (range, 0.0-0.87), and agitation 0.26 (range, 0.09-0.77). Meta-analysis revealed no correlation between dexmedetomidine exposure variables and withdrawal signs. A moderate negative monotonic relationship existed between the proportion of patients who had undergone cardiac surgery and the proportion experiencing hypertension (correlation coefficient, -0.47; p = 0.048) and tachycardia (correlation coefficient, -0.57; p = 0.008), indicating that in cohorts with a higher proportion of patients who were postcardiac surgery, there were fewer occurrences of hypertension and or tachycardia. CONCLUSIONS: On review of the 2000-2022 literature, dexmedetomidine withdrawal may be characterized by tachycardia, hypertension, or agitation, particularly with higher cumulative doses or prolonged durations. Since most studies included in the review were retrospective, prospective studies are needed to further clarify risk factors, establish diagnostic criteria, and identify optimal management strategies.

Children's arithmetic strategy use trajectories: Exploring the roles of executive functions and sociodemographic characteristics.

Although young children often use counting to solve arithmetic problems, over time they move toward more efficient strategies such as direct retrieval and decomposition. Strategy selection has longitudinal associations with children's math achievement. Existing research indicates that children's executive functions (EFs) support inhibiting unnecessary strategies and adaptively switching between strategies. Moreover, research has documented gender differences in strategy use, but prior literature does not account for the contributions of socioeconomic factors in children's strategy trajectories. The current study examined the unique roles of preschoolers' EFs, gender, household income, and maternal education for the trajectories of strategy use on arithmetic problems across early elementary school. Preschoolers' EFs were assessed at 5 years 3 months of age, and children completed addition and subtraction problems in first, second, and third grades. Children's strategies were categorized as retrieval, counting, decomposition, and sign flipping. Results indicated that children with higher EFs were more likely to use retrieval and sign flipping in first grade compared with children with lower EFs, and this advantage was maintained into third grade. Boys used more retrieval and decomposition, whereas girls used more counting strategies, in first grade, and this pattern held longitudinally. Finally, children whose mothers had more years of education were likely to use decomposition and sign flipping in first grade, with an advantage through third grade. Overall, the current study sheds light on how cognitive and sociodemographic factors differentially contribute to children's accurate strategy use, with implications for how to best target early interventions to support children's math achievement.

Impacts of heat stress on the accuracy of an ear-tag accelerometer for monitoring rumination and eating behavior in dairy-beef cross cattle using an automated gold standard.

Accelerometer-based technologies can be utilized for precision monitoring of feeding behaviors, but limited information is available regarding the impact of varying environmental conditions on sensor performance. The objective of this study was to determine if a commercially available ear-tag sensor (CM; CowManager SensOor, Agis Automatisering BV) could accurately quantify eating and rumination time under heat stress conditions. Data obtained from CM sensors was compared with data collected using an automated gold standard (RW; Rumiwatch System; Itin+Hoch). Automated measurements were obtained from 2 experiments in which cattle were exposed to heat stress conditions. In the principal study (Experiment 1), 3428 h of data were collected from 9 Holstein × Angus steers (470.9 ± 23.9 kg) subjected to either thermoneutral (TN; 21.0°C; 64.0% humidity; temperature-humidity index [THI] = 67; 12- and 12-h light and dark cycle; n = 1714 h), or heat stress conditions (HS; cyclical daily temperatures to mimic diurnal patterns; 0800 - 2000 h: 33.6°C, 40.0% RH, THI: 83.5; 2000 - 0800 h: 23.2°C, 70.0% RH; THI: 70.3; n = 1714 h). Data (n = 719 h) from 6 Holstein x Angus steers (487.9 ± 9.1 kg) were obtained from a subsequent experiment (Experiment 2) to confirm consistency of ear-tag accelerometer performance under elevated THI (HS conditions as described above). In Experiment 1, CM was capable of quantifying rumination time with high accuracy under TN conditions (concordance correlation coefficient [CCC]: 0.75 - 0.81). Overall, agreement between CM and the automated gold standard declined 6 - 7% during HS, which was most apparent later in the day when cattle had been subjected to HS for multiple hours (moderate agreement; CCC: 0.68). Accuracy for rumination time was also only moderate for data collected during Experiment 2 (CCC: 0.55 - 0.61). In contrast, CM reported total eating (eating with the head down + head up while masticating) time with moderate accuracy for TN (CCC: 0.53 - 0.54), only achieved negligible to low accuracy during HS (CCC: 0.39 - 0.44 [Experiment 1] and 0.17 - 0.34 [Experiment 2]). Sensor performance did improve when CM eating time was compared specifically to the time spent with the head down reported by RW; HS still negatively influenced sensor performance, however, with high agreement during TN (CCC: 0.72 - 0.73) but low to moderate agreement during HS (CCC: 0.65 - 0.69 [Experiment 1] and 0.40 - 0.58 [Experiment 2]). Results of this study suggest accuracy of ear-tag accelerometers may be impaired when cattle are subjected to heat stress.

Associations between middle childhood executive control aspects and adolescent substance use and externalizing and internalizing problems.

This study examines the degree to which two middle childhood executive control aspects, working memory and combined inhibitory control/flexible shifting, predict adolescent substance use and externalizing and internalizing problems. Participants were 301 children (ages 3-6 years; 48.2% male) recruited from a Midwestern city in the United States and followed into adolescence (ages 14-18 years). Working memory had a statistically significant unadjusted association with externalizing problems (r = -.30, p = .003) in a confirmatory factor analysis. Neither factor significantly predicted any of the adolescent outcomes in a structural equation model that adjusted for each EC aspect, sociodemographic covariates, and middle childhood externalizing and internalizing problems. Stronger prediction of EC aspects might not emerge until they become more fully differentiated later in development.

Tinnitus after COVID-19 vaccination: Findings from the vaccine adverse event reporting system and the vaccine safety datalink.

PURPOSE: To assess the occurrence of tinnitus following COVID-19 vaccination using data mining and descriptive analyses in two U.S. vaccine safety surveillance systems. METHODS: Reports of tinnitus after COVID-19 vaccination to the Vaccine Adverse Event Reporting System (VAERS) from 2020 through 2024 were examined using empirical Bayesian data mining and by calculating reporting rates. In the Vaccine Safety Datalink (VSD) population, ICD-10 coded post-vaccination medical visits were examined using tree-based data mining, and tinnitus visit incidence rates during post-vaccination days 1-140 were calculated by age group for COVID-19 vaccines and for comparison, influenza vaccine. RESULTS: VAERS data mining did not find disproportionate reporting of tinnitus for any COVID-19 vaccine. VAERS received up to 84.82 tinnitus reports per million COVID-19 vaccine doses administered. VSD tree-based data mining found no signals for tinnitus. VSD tinnitus visit incidence rates after COVID-19 vaccines were similar to those after influenza vaccine except for the group aged ≥65 years (Moderna COVID-19 vaccine, 165 per 10,000 person-years; Pfizer-BioNTech COVID-19 vaccine, 154; influenza vaccine, 135). CONCLUSIONS: Overall, these findings do not support an increased risk of tinnitus following COVID-19 vaccination but cannot definitively exclude the possibility. Descriptive comparisons between COVID-19 and influenza vaccines were limited by lack of adjustment for potential confounding factors.

Exploring the Interaction Between Preschool Executive Control and Caregiver Emotion Socialization in Predicting Adolescent Weight Trajectories.

There is a critical need for research examining how neural vulnerabilities associated with obesity, including lower executive control, interact with family factors to impact weight trajectories across adolescence. Utilizing a longitudinal design, the present study investigated caregivers' emotion socialization practices as a moderator of the association between preschool executive control and adolescent body mass index (BMI) trajectories. Participants were 229 youth (Mage = 5.24, SD = 0.03; 47.2% assigned female at birth; 73.8% White, 3.9% Black, 0.4% Asian American, 21.8% multiracial; 12.7% Hispanic) enrolled in a longitudinal study. At preschool-age, participants completed performance-based executive control tasks, and their caregivers reported on their typical emotion-related socialization behaviors (i.e., supportive and nonsupportive responses to children's negative emotions). Participants returned for annual laboratory visits at ages 14 through 17, during which their height and weight were measured to calculate BMI. Although neither preschool executive control nor caregiver emotion-related socialization behaviors were directly associated with BMI growth in adolescence, supportive responses moderated the association between executive control and BMI trajectories. The expected negative association between lower preschool executive control and greater BMI growth was present at below average levels of supportive responses, suggesting that external regulation afforded by supportive responses might reduce risk for adolescent overweight and obesity among children with lower internal self-regulatory resources during preschool. Findings highlight the importance of efforts to bolster executive control early in development and targeted interventions to promote effective caregiver emotion socialization (i.e., more supportive responses) for youth with lower internal self-regulatory abilities to mitigate risk for overweight and obesity and promote health across childhood and adolescence.

Improving Methods of Identifying Anaphylaxis for Medical Product Safety Surveillance Using Natural Language Processing and Machine Learning.

We sought to determine whether machine learning and natural language processing (NLP) applied to electronic medical records could improve performance of automated health-care claims-based algorithms to identify anaphylaxis events using data on 516 patients with outpatient, emergency department, or inpatient anaphylaxis diagnosis codes during 2015-2019 in 2 integrated health-care institutions in the Northwest United States. We used one site's manually reviewed gold-standard outcomes data for model development and the other's for external validation based on cross-validated area under the receiver operating characteristic curve (AUC), positive predictive value (PPV), and sensitivity. In the development site 154 (64%) of 239 potential events met adjudication criteria for anaphylaxis compared with 180 (65%) of 277 in the validation site. Logistic regression models using only structured claims data achieved a cross-validated AUC of 0.58 (95% CI: 0.54, 0.63). Machine learning improved cross-validated AUC to 0.62 (0.58, 0.66); incorporating NLP-derived covariates further increased cross-validated AUCs to 0.70 (0.66, 0.75) in development and 0.67 (0.63, 0.71) in external validation data. A classification threshold with cross-validated PPV of 79% and cross-validated sensitivity of 66% in development data had cross-validated PPV of 78% and cross-validated sensitivity of 56% in external data. Machine learning and NLP-derived data improved identification of validated anaphylaxis events.

COVID-19 Vaccine Safety Surveillance in Early Pregnancy in the United States: Design Factors Affecting the Association Between Vaccine and Spontaneous Abortion.

In the Vaccine Safety Datalink (VSD), we previously reported no association between coronavirus disease 2019 (COVID-19) vaccination in early pregnancy and spontaneous abortion (SAB). The present study aims to understand how time since vaccine rollout or other methodological factors could affect results. Using a case-control design and generalized estimating equations, we estimated the odds ratios (ORs) of COVID-19 vaccination in the 28 days before a SAB or last date of the surveillance period (index date) in ongoing pregnancies and occurrence of SAB, across cumulative 4-week periods from December 2020 through June 2021. Using data from a single site, we evaluated alternative methodological approaches: increasing the exposure window to 42 days, modifying the index date from the last day to the midpoint of the surveillance period, and constructing a cohort design with a time-dependent exposure model. A protective effect (OR = 0.78, 95% confidence interval: 0.69, 0.89), observed with 3-cumulative periods ending March 8, 2021, was attenuated when surveillance extended to June 28, 2021 (OR = 1.02, 95% confidence interval: 0.96, 1.08). We observed a lower OR for a 42-day window compared with a 28-day window. The time-dependent model showed no association. Timing of the surveillance appears to be an important factor affecting the observed vaccine-SAB association.

Active Postlicensure Safety Surveillance for Recombinant Zoster Vaccine Using Electronic Health Record Data.

Recombinant zoster vaccine (RZV) (Shingrix; GlaxoSmithKline, Brentford, United Kingdom) is an adjuvanted glycoprotein vaccine that was licensed in 2017 to prevent herpes zoster (shingles) and its complications in older adults. In this prospective, postlicensure Vaccine Safety Datalink study using electronic health records, we sequentially monitored a real-world population of adults aged ≥50 years who received care in multiple US Vaccine Safety Datalink health systems to identify potentially increased risks of 10 prespecified health outcomes, including stroke, anaphylaxis, and Guillain-Barré syndrome (GBS). Among 647,833 RZV doses administered from January 2018 through December 2019, we did not detect a sustained increased risk of any monitored outcome for RZV recipients relative to either historical (2013-2017) recipients of zoster vaccine live, a live attenuated virus vaccine (Zostavax; Merck & Co., Inc., Kenilworth, New Jersey), or contemporary non-RZV vaccine recipients who had an annual well-person visit during the 2018-2019 study period. We confirmed prelicensure trial findings of increased risks of systemic and local reactions following RZV. Our study provides additional reassurance about the overall safety of RZV. Despite a large sample, uncertainty remains regarding potential associations with GBS due to the limited number of confirmed GBS cases that were observed.

Validation of Acute Pancreatitis Among Adults in an Integrated Healthcare System.

BACKGROUND: Acute pancreatitis is a serious gastrointestinal disease that is an important target for drug safety surveillance. Little is known about the accuracy of ICD-10 codes for acute pancreatitis in the United States, or their performance in specific clinical settings. We conducted a validation study to assess the accuracy of acute pancreatitis ICD-10 diagnosis codes in inpatient, emergency department (ED), and outpatient settings. METHODS: We reviewed electronic medical records for encounters with acute pancreatitis diagnosis codes in an integrated healthcare system from October 2015 to December 2019. Trained abstractors and physician adjudicators determined whether events met criteria for acute pancreatitis. RESULTS: Out of 1,844 eligible events, we randomly sampled 300 for review. Across all clinical settings, 182 events met validation criteria for an overall positive predictive value (PPV) of 61% (95% confidence intervals [CI] = 55, 66). The PPV was 87% (95% CI = 79, 92%) for inpatient codes, but only 45% for ED (95% CI = 35, 54%) and outpatient (95% CI = 34, 55%) codes. ED and outpatient encounters accounted for 43% of validated events. Acute pancreatitis codes from any encounter type with lipase >3 times the upper limit of normal had a PPV of 92% (95% CI = 86, 95%) and identified 85% of validated events (95% CI = 79, 89%), while codes with lipase <3 times the upper limit of normal had a PPV of only 22% (95% CI = 16, 30%). CONCLUSIONS: These results suggest that ICD-10 codes accurately identified acute pancreatitis in the inpatient setting, but not in the ED and outpatient settings. Laboratory data substantially improved algorithm performance.

ROAR ED-SANE: A Retrospective Observational Assessment Review of an Emergency Department Sexual Assault Nurse Examiner Program's Adherence to Centers for Disease Control and Prevention Guidelines for Sexually Transmitted Infections.

BACKGROUND: Sexual assault survivors are at increased risk for sexually transmitted infections. Sexual Assault Nurse Examiner programs guide sexually transmitted infection treatment, monitoring, and follow-up scheduling according to guidelines by the Centers for Disease Control and Prevention (CDC). Reported low rates of provider adherence to CDC treatment guidelines and patient adherence to follow-up necessitate a review of medication prescribing and follow-up scheduling practices, especially at smaller community hospitals in the United States. METHODS: A retrospective medical record review was conducted to assess adherence rates to CDC guidelines for prescribing practices, scheduling, and follow-up of sexual assault survivors. We included pediatric and adult patients presenting to the emergency department (ED) and participating in the ED Sexual Assault Nurse Examiner program at a rural, community-based teaching hospital in La Crosse, WI, from January 2018 to December 2021. Descriptive statistics were used to evaluate results. RESULTS: Analysis included 103 patients. Prescribing adherence to CDC guidelines was >80% for all except human immunodeficiency virus (53.4%), trichomoniasis (68.1%), and hepatitis B (69%). Of the 38 patients who had a follow-up scheduled during their ED encounter, 78.9% attended their scheduled follow-up and 94.7% of those appointments were scheduled within the CDC-recommended time frame, leading to an overall adherence of 40%. CONCLUSIONS: Adherence rates were high for most prescribing practices, and attendance of scheduled follow-up was higher than expected. Opportunities to improved adherence to CDC guidelines were identified in prescribing for 3 disease states (human immunodeficiency virus, trichomoniasis, and hepatitis B) and in scheduling of follow-up.

Does preschool executive control mediate the impact of early environmental unpredictability and deprivation on the general factor of psychopathology a decade later?

BACKGROUND: Although deprivation has been consistently shown to increase risk for psychopathology through impaired executive control, the unique effects of other dimensions of early adversity, such as unpredictability, on executive control development are poorly understood. The current study evaluated whether deprivation and/or unpredictability early in life have unique effects on the general factor of psychopathology through impaired preschool executive control. METHODS: Participants included 312 children (51% female) oversampled for greater sociodemographic risk. Preschool executive control was measured using a battery of nine developmentally appropriate executive control tasks. Dimensions of adversity were measured with observational and caregiver assessments, and psychopathology was measured with caregiver and child reports. RESULTS: In separate models, both deprivation and unpredictability had significant indirect effects on the adolescent general factor of psychopathology through impaired preschool executive control. However, when both dimensions of adversity were included simultaneously, early life deprivation, but not unpredictability, was uniquely associated with the general factor of psychopathology in adolescence through impaired preschool executive control. CONCLUSIONS: Preschool executive control appears to be a transdiagnostic mechanism through which deprivation, but not unpredictability, increases risk for the general factor of psychopathology in adolescence. Results elucidate potential transdiagnostic targets for intervention efforts aimed at reducing the development and maintenance of psychopathology across the life span.

Ten simple rules for designing and running a computing minor for bio/chem students.

Science students increasingly need programming and data science skills to be competitive in the modern workforce. However, at our university (San Francisco State University), until recently, almost no biology, biochemistry, and chemistry students (from here bio/chem students) completed a minor in computer science. To change this, a new minor in computing applications, which is informally known as the Promoting Inclusivity in Computing (PINC) minor, was established in 2016. Here, we present the lessons we learned from our experience in a set of 10 rules. The first 3 rules focus on setting up the program so that it interests students in biology, chemistry, and biochemistry. Rules 4 through 8 focus on how the classes of the program are taught to make them interesting for our students and to provide the students with the support they need. The last 2 rules are about what happens "behind the scenes" of running a program with many people from several departments involved.

Preschool Executive Control, Temperament, and Adolescent Dietary Behaviors.

BACKGROUND: Child temperament styles characterized by increased emotionality or pleasure seeking may increase risk for less healthful eating patterns, while strong executive control (EC) may be protective. The interaction of these characteristics with longitudinal outcomes has not yet been examined. PURPOSE: The aim of this study was to examine the association of preschool temperament and EC, as well as their interaction with adolescent eating. METHODS: Preschoolers (N = 313) were recruited into a longitudinal study, with behavioral measurement of EC at age 5.25 years, temperament assessed multiple times across preschool, and eating outcomes assessed in adolescence (mean age = 15.34 years). RESULTS: Separate latent moderated structural equation models demonstrated that weaker EC was associated with eating less healthful foods, including high sugar foods, sugar-sweetened beverages (SSBs), and convenience foods (p < .05). In the moderation models, negative affectivity temperament was correlated with eating less healthful foods, high sugar foods, and SSBs (p < .05). Children lower in surgency/extraversion temperament were more likely to drink SSBs. There was an interaction between temperament and EC, such that children high in negative affectivity with weaker EC were particularly more likely to consume less healthful foods, high sugar foods, and SSBs (p < .05). There was no interaction of surgency with EC and food consumption. CONCLUSIONS: Child characteristics measured early in development were associated with later adolescent eating behaviors. Adequate EC could be necessary to counteract the drive toward eating associated with temperaments high in negative affectivity.

A preschool temperament style called Negative Affectivity, characterized by high levels of reactivity and negative emotion, predicted eating patterns a decade later. These children were more likely to eat less healthful foods and drink sugary drinks as adolescents. Strong executive function skills were important for redirecting toward healthful eating in children with Negative Affectivity.

Racial and ethnic disparities in influenza vaccination coverage among pregnant women in the United States: The contribution of vaccine-related attitudes.

OBJECTIVE: Racial and ethnic disparities in influenza vaccination coverage among pregnant women in the United States have been documented. This study assessed the contribution of vaccine-related attitudes to coverage disparities. METHODS: Surveys were conducted following the 2019-2020 and 2020-2021 influenza seasons in a US research network. Using electronic health record data to identify pregnant women, random samples were selected for surveying; non-Hispanic Black women and influenza-unvaccinated women were oversampled. Regression-based decomposition analyses were used to assess the contribution of vaccine-related attitudes to racial and ethnic differences in influenza vaccination. Data were combined across survey years, and analyses were weighted and accounted for survey design. RESULTS: Survey response rate was 41.2% (721 of 1748) for 2019-2020 and 39.3% (706 of 1798) for 2020-2021. Self-reported influenza vaccination was higher among non-Hispanic White respondents (79.4% coverage, 95% CI 73.1%-85.7%) than Hispanic (66.2% coverage, 95% CI 52.5%-79.9%) and non-Hispanic Black (55.8% coverage, 95% CI 50.2%-61.4%) respondents. For all racial and ethnic groups, a high proportion (generally >80%) reported being seen for care, recommended for influenza vaccination, and offered vaccination. In decomposition analyses, vaccine-related attitudes (e.g., worry about vaccination causing influenza; concern about vaccine safety and effectiveness) explained a statistically significant portion of the observed racial and ethnic disparities in vaccination. Maternal age, education, and health status were not significant contributors after controlling for vaccine-related attitudes. CONCLUSIONS: In a setting with relatively high influenza vaccination coverage among pregnant women, racial and ethnic disparities in coverage were identified. Vaccine-related attitudes were associated with the disparities observed.

Pediatric extracorporeal life support for refractory status asthmaticus: ELSO Registry trends from the past decade.

BACKGROUND: Extracorporeal life support (ECLS) for status asthmaticus (SA) is rare. Increased safety and experience may increase utilization of ECLS for SA. METHODS: We reviewed pediatric (<18 years old) patients requiring ECLS for SA between 1998 and 2019 within the Extracorporeal Life Support Organization (ELSO) Registry and Nemours Children's Health (NCH) system. We compared patient characteristics, pre-ECLS medications, clinical data, complications, and survival to discharge between Early (1988-2008) and Late (2009-2019) eras. RESULTS: From the ELSO Registry, we identified 173 children, 53 in Early and 120 in Late eras, with primary diagnosis of SA. Pre-ECLS hypercarbic respiratory failure was similar between eras (median pH 7.0 and pCO2 111 mm Hg). Venovenous mode (79% vs. 82%), median ECLS time (116 vs. 99 h), time to extubation (53 vs. 62 h), and hospital survival (89% vs. 88%) also remained similar. Intubation to cannulation time significantly decreased (20 vs. 10 h, p = 0.01). ECLS without complication occurred more in the Late era (19% vs. 39%, p < 0.01), with decreased hemorrhagic (24% vs. 12%, p = 0.05) and noncannula-related mechanical (19% vs. 6%, p = 0.008) complications. Within NCH, we identified six Late era patients. Pre-ECLS medication favored intravenous beta agonists, bronchodilators, magnesium sulfate, and steroids. One patient died from neurological complications following pre-ECLS cardiac arrest. CONCLUSIONS: Collective experience supports ECLS as a rescue therapy for pediatric SA. Survival to discharge remains good, and complication rates have improved. Pre-ECLS cardiac arrest may potentiate neurologic injury and impact survival. Further study is needed to evaluate causal relationships between complications and outcomes.
