A Coproduced Family Reporting Intervention to Improve Safety Surveillance and Reduce Disparities.

OBJECTIVES: Examine family safety-reporting after implementing a parent-nurse-physician-leader coproduced, health literacy-informed, family safety-reporting intervention for hospitalized families of children with medical complexity. METHODS: We implemented an English and Spanish mobile family-safety-reporting tool, staff and family education, and process for sharing comments with unit leaders on a dedicated inpatient complex care service at a pediatric hospital. Families shared safety concerns via predischarge surveys (baseline and intervention) and mobile tool (intervention). Three physicians with patient safety expertise classified events. We compared safety-reporting baseline (via survey) versus intervention (via survey and/or mobile tool) with generalized estimating equations and sub-analyzed data by COVID-19-era and educational attainment. We also compared mobile tool-detected event rates with hospital voluntary incident reporting. RESULTS: 232 baseline and 208 intervention parents participated (78.2% consented); 29.5% of baseline families versus 38.2% of intervention families reported safety concerns (P = .09). Adjusted odds ratio (95% CI) of families reporting safety concerns intervention versus baseline was 1.6 (1.0-2.6) overall, 2.6 (1.3-5.4) for those with < college education, and 3.1 (1.3-7.3) in the COVID-19-era subgroup. Safety concerns reported via mobile tool (34.6% of enrolled parents) included 42 medical errors, 43 nonsafety-related quality issues, 11 hazards, and 4 other. 15% of mobile tool concerns were also detected with voluntary incident reporting. CONCLUSIONS: Family safety-reporting was unchanged overall after implementing a mobile reporting tool, though reporting increased among families with lower educational attainment and during the COVID-19 pandemic. The tool identified many events not otherwise captured by staff-only voluntary incident reporting. Hospitals should proactively engage families in reporting to improve safety, quality, and equity.

Perceptions of Harm and Addictiveness for Nicotine Products, THC e-Cigarettes, and e-Cigarettes with Other Ingredients Among Adolescents, Young Adults, and Adults.

BACKGROUND: Perceptions of health harms and addictiveness related to nicotine products, THC e-cigarettes, and e-cigarettes with other ingredients are an important predictor of use. This study examined differences in perceived harm and addiction across such products among adolescents, young adults, and adults. METHODS: We conducted a cross-sectional survey (N = 6,131, ages 13-40 years old) in which participants reported perceived harm and addictiveness for 11 products (cigarettes, disposable nicotine e-cigarettes, pod-based nicotine e-cigarettes, other nicotine e-cigarettes, THC e-cigarettes, e-cigarettes with other ingredients, nicotine pouches, nicotine lozenges, nicotine gums, nicotine tablets, nicotine toothpicks). We applied adjusted regression models and conducted pairwise comparisons between age groups (13-17, 18-20, 21-25, and 26-40) and product use status (never, ever, and past-30-day use), adjusting for gender, race/ethnicity, sexual orientation, and financial comfort. RESULTS: Overall, participants in younger age groups perceived products to be more harmful and addictive than those in older age groups, with the exception of e-cigarettes with other ingredients. For all products, participants who never used perceived each product to be more harmful than those who ever used. For all products, participants who used the products in the past 30-days had lower perceived harm and addictiveness compared to never and ever use. Certain sociodemographic groups, such as people who identify as LGBTQ+, Non-Hispanic Black, or Hispanic, had lower perceived harm and addictiveness for most products. DISCUSSION: Efforts should be made to educate all age groups and minoritized groups on harms and addictiveness of all nicotine products, THC e-cigarettes, and e-cigarettes with other ingredients.

Post-mortem to ante-mortem facial image comparison for deceased migrant identification.

The identification of deceased migrants is a global challenge that is exacerbated by migration distance, post-mortem conditions, access to ante-mortem data for comparison, inconsistent international procedures and lack of communication between arrival and origin countries. Due to low technology requirements, fast speed analysis and ease of transferring digital data, facial image comparison is particularly beneficial in those contexts, especially in challenging scenarios when this may be the only initial ante-mortem data available to identify the deceased. The Facial Identification Scientific Working Group (FISWG) professional guidelines for facial image comparison were developed for living facial appearance, and, therefore, a tailored protocol for the application of post-mortem to ante-mortem facial image comparison was proposed and evaluated in this research. The protocol was investigated via an inter-observer and an accuracy study, using 29 forensic cases (2001-2020) from the University of Milan, provided by the Laboratory of Forensic Anthropology and Odontology. In order to replicate a migrant identification scenario, each post-mortem subject was compared to all 29 ante-mortem targets (841 comparisons). The protocol guided the practitioner through stages of facial image comparison, from broad (phase 1) to more detailed (phase 3), eventually leading to a decision of 'exclusion' or 'potential match' for each post-mortem to ante-mortem case (phase 4). In phase 4, a support scale was also utilised to indicate the level of confidence in a potential match. Each post-mortem subject could be recorded with multiple potential matches. The protocol proved to be useful guide for facial image comparison, especially for less experienced practitioners and the inter-observer study suggested good reproducibility. The majority (82-96%) of ante-mortem subjects were excluded at the first stage of the protocol, and 71 full post-mortem to ante-mortem facial image comparisons were carried out. On average, two or three potential matches were recorded for each post-mortem subject. The overall accuracy rate was 85%, with the majority (79%) of ante-mortem non-targets correctly excluded from the identification process. An increased number and quality of available ante-mortem images produced more successful matches with higher levels of support. All potential matches involving non-targets received low levels of support, and for 73% of the post-mortem subjects, the ante-mortem target was the only recorded potential match. However, two ante-mortem targets were incorrectly excluded (one at the first stage of the protocol) and therefore changes to the protocol were implemented to mitigate these errors. A full protocol and a practical recording chart for practitioner use is included with this paper.

Trends in HIE and Use of Hypothermia in California: Opportunities for Improvement.

BACKGROUND AND OBJECTIVES: Hypoxic-ischemic encephalopathy (HIE) is a leading cause of neonatal morbidity and mortality. Therapeutic hypothermia (TH), a proven treatment of moderate-severe HIE, was first used clinically after 2006. We describe trends in HIE diagnosis and use of TH over a 10-year period in California. METHODS: We identified 62 888 infants, ≥36 weeks gestation, who were cared for in California Perinatal Quality Care Collaborative-participating NICUs between 2010 and 2019, and linked them to birth certificate data. We evaluated trends in HIE diagnosis and use of TH. RESULTS: Over time, rates of HIE diagnosis increased from 0.6 to 1.7 per 1000 live births, and use of TH increased from 26.5 to 83.0 per 1000 infants. Rates of moderate HIE increased more than mild or severe, although use of TH for mild HIE increased more than for moderate. Of those with moderate-severe HIE, 25% remain untreated. Treatment varied by NICU level of care. CONCLUSIONS: The rates of HIE and TH increased steadily. Some infants with moderate-severe HIE remain untreated, suggesting a need for ongoing education. Further evaluation of systems of care is needed to assure all qualifying infants are treated.

Intention to quit or reduce e-cigarettes, cannabis, and their co-use among a school-based sample of adolescents.

INTRODUCTION: Little is known about the prevalence and predictors of adolescents' intention to quit or reduce use of e-cigarettes and/or cannabis. METHODS: Frequencies of intention to change (quit, reduce) e-cigarettes and/or cannabis use were examined among 23,915 surveyed middle and high school students with sole and co-use. Predictors of intention to change were identified via LASSO/multilevel logistic regression. RESULTS: Among those with sole e-cigarette use (n = 543), 40.9 % intended to quit and 24.1 % intended to reduce; non-daily e-cigarette use predicted intention to quit and reduce e-cigarettes (p's < 0.03). Among those with sole cannabis use (n = 546), 10.6 % intended to quit and 25.1 % intended to reduce; absence of cannabis cravings predicted intention to reduce cannabis use (p < 0.01). Among those with co-use (n = 816), 26.2 % intended to either quit or reduce (quit/reduce) both substances, 27.5 % intended to quit/reduce e-cigarettes only, and 6.9 % intended to quit/reduce cannabis only. No predictors emerged for intention to change e-cigarette use among those with co-use (p's > 0.09), but younger age, lack of poly-tobacco use, and lack of cannabis craving predicted intention to quit/reduce cannabis use (p's < 0.04). CONCLUSIONS: More than half of adolescents with past-month e-cigarette use, regardless of concurrent cannabis use, expressed interest in changing their use. However, only heaviness of e-cigarette use emerged as a predictor of intention to change suggesting. While fewer students expressed interest in changing their cannabis use, cannabis cravings and poly-tobacco use predicted intent to change. Overall, findings emphasize the need to tailor interventions towards adolescents engaging in more problematic substance use patterns.

Popularity of Zyn and other nicotine pouch brands among U.S. adolescents, young adults, and adults in 2021.

OBJECTIVE: This study identifies brands of nicotine pouches used in 2021, just before the surge in popularity of Zyn use. METHODS: We conducted a national, cross-sectional online survey of a general U.S. population (November to December 2021; N = 6131; age 13-40) via Qualtrics panels. Descriptive analyses and chi-squared tests (alpha = 0.05) were performed to assess ever and past-30-day use of nicotine pouch brands across adolescents (13-20), young adults (21-24), and adults (25-40), and to assess frequency of popular brands used among peers. RESULTS: The top brands ever used were Zyn (overall: 30.9%; adolescents: 31.9%; young adults: 33.2%; adults: 28.3%) and Lyft (overall: 28.8%; adolescents: 28.4%; young adults: 32.9%; adults: 26.3%), with no differences in ever-use by age group (p's > 0.095). The top brands used in the past-30-days were Zyn (overall: 26.4%; adolescents: 24.5%; young adults: 24.3%; adults: 30.0%) and Rush (overall: 24.2%; adolescents: 21.0%; young adults: 22.7%; adults: 28.6%). Adults (vs. adolescents, young adults) were more likely to report past-30-day use of Lyft (p = 0.004). Participants indicated Zyn (18.5%) and Lyft (18.2%) to be the most popular brands among peers. CONCLUSIONS: Even in 2021, Zyn was the most popular brand of nicotine pouches. Findings will help regulate and reduce impact of marketing of Zyn.

Products and patterns through which adolescents, young adults, and adults initiate co-use of tobacco and cannabis.

BACKGROUND: Co-use of tobacco and cannabis is common. However, few studies have examined the temporal sequencing through which individuals initiate co-use, and how these patterns vary across age. This study addresses this gap by examining the specific products and temporal sequencing through which adolescents, young adults, and adults initiate co-use of tobacco and cannabis. Among adolescents, young adults, and adults who co-used tobacco and cannabis in the past 30 days, we examined (a) whether tobacco or cannabis was used first in their lifetime and (b) which specific tobacco or cannabis product (e.g., nicotine e-cigarettes, cannabis edibles) was the first used. METHODS: Data were from a cross-sectional national survey (N = 6,131, 13-40 years old) in which participants reported ever use, past-30-day-use, and order of use for 17 different tobacco and cannabis products. Results were analyzed overall and by age group (13-20; 21-24; 25-40). RESULTS: 38.4% of participants reported use of both tobacco and cannabis in the past 30 days. Among these participants, 70.9% used tobacco first in their lifetime (66.6% < 21; 71.7% 21-24; 76.6% > 24). Approximately 60% of participants who initiated co-use with tobacco reported nicotine e-cigarettes as their first tobacco product (63.3% < 21; 66.7% 21-24; 49.6% > 24). CONCLUSIONS: The majority of participants who used both tobacco and cannabis used tobacco first in their lifetime, and nicotine e-cigarettes were the most common form of tobacco initiation, particularly among adolescents and young adults. Findings emphasize the need for co-use prevention programs to target common products of initiation.

Education, organizational changes, and enforcement challenges of the 2019 flavored tobacco sales restriction in Massachusetts.

OBJECTIVES: In November 2019, the Massachusetts legislature passed An Act Modernizing Tobacco Control and became the first state to restrict retail sales of all flavored (including menthol) cigarettes, e-cigarettes, and other tobacco products (the Act). Additional tobacco control policies and health insurance coverage for tobacco treatment were included as part of the Act. Implementation of these policies occurred between November 2019 and June 2020. This study explored challenges and facilitators during the implementation of the Act experienced by public health officials, school personnel, and healthcare providers. METHODS: We conducted in-depth interviews with a purposive sample of 9 public health officials and advocates, 9 school personnel, and 8 healthcare providers from March to December 2021. We conducted thematic analysis of interview transcripts using inductive codes of key themes emerging from the interviews. RESULTS: Interviewees highlighted three key themes that impacted the implementation of the Act: 1) Education of those impacted by the Act, 2) Organizational-level changes to incorporate the Act, and 3) Enforcement challenges. Examples of challenges to the implementation of the Act included COVID-19 pandemic restrictions, navigating tobacco industry tactics around naming flavors, and confusion regarding health insurance coverage for tobacco use cessation programs. Examples of facilitators were enforcement leading to retailer compliance, committed advocacy efforts of leadership/champions, and strong coordination within and between organizations. CONCLUSIONS: These findings of Massachusetts's experience in policy implementation can inform the preparation to implement similar tobacco control policies in other states.

Adverse Childhood Experiences (ACEs) in Unhoused Children Increase Odds of Psychiatric Illness, Physical Illness, and Psychiatric Admission.

Unhoused children and adolescents have high rates of adverse childhood experiences (ACEs). The objective of this study was to characterize a large cohort of unhoused children and investigate rates of psychiatric diagnoses, medical diagnoses, and utilization of emergency department (ED) resources depending on the presence of additional documented ACEs. A retrospective cohort of all unhoused children who presented to the ED of a large Midwestern health system from January 2014 to July 2019 were included. Unhoused status was determined by address field or ICD-10 code for homelessness (Z59.0). Demographics and ED visits were extracted from the electronic health record. Past medical history, ACEs, chief complaint (CC), length of stay (LOS), imaging, and labs were extracted by chart review. T-tests, chi square tests, and Fisher's exact tests were completed for each sub-analysis. Unhoused children with at least one additional ACE had higher odds of the following psychiatric disorders: depression (OR = 5.2, 95% CI = 3.4- 7.9), anxiety (OR = 3.4, 95% CI = 32.1-5.5), behavioral disorder (OR = 7.2, 95% CI = 35.1- 10.4), psychoses (OR = 6.0, 1.9-18.4), bipolar disorder (OR = 19.8, 95% CI = 34.6-84.9), suicidal ideation (OR = 8.0, 95% CI = 34.8-13.4), post-traumatic stress disorder (OR = 10.1, 95% CI = 35.4-18.6), and attention deficit hyperactive disorder (OR = 4.1, 3.0-5.7). Patients with additional documented ACEs were also more likely to have a prior psychiatric admission (p < 0.001). Unhoused children and adolescents with exposure to additional documented ACEs are more likely to have some serious psychiatric and medical diagnoses compared to other unhoused children.

Impacts of the Massachusetts 2019 An Act Modernizing Tobacco Control on tobacco retailer settings: A multi-methods study.

BACKGROUND: In November 2019, the Massachusetts legislature passed An Act Modernizing Tobacco Control and became the first state to restrict retail sales of all flavored (including menthol) cigarettes, e-cigarettes, and other tobacco products. Our study aims to provide the retailer experience of the new law from the perspectives of multiple stakeholders, including tobacco retailers themselves, public health officials, and Massachusetts residents. METHODS: We conducted in-depth interviews with seven tobacco retailers and ten public health officials from March 2021 to April 2022. Monthly repeated cross-sectional surveys were administered through the online survey panel Prodege from April 2021 to August 2022 (adult sample: N = 765; adolescent sample: N = 900). Themes from interviews were identified by drawing on deductive codes informed by the interview guide, followed by inductive coding of data. Survey data were descriptively analyzed in R. RESULTS: Key themes included retailer frustration over loss of sales to neighboring states, factors associated with retailer compliance, and the need for increased education regarding the law. Survey results showed that a minority of adolescents (13.3%) and adults (26.1%) who vaped in the past 30-days were traveling to border states to purchase vape products. Less than one-quarter of adolescent participants and less than half of adult participants could correctly identify which products Massachusetts did not sell. CONCLUSIONS: Evidence from the retailer, public health, and end-user perspectives support mutual benefits of adjacent states enacting flavored tobacco sales restrictions, improved policy education for retailers and the public, and improved retailer enforcement.

Key Informants' Perceptions of Health Equity and Racial Justice Impacts of the 2019 Massachusetts An Act Modernizing Tobacco Control.

INTRODUCTION: The Massachusetts legislature passed An Act Modernizing Tobacco Control in November 2019 to restrict retail sales of flavored commercially manufactured tobacco products including menthol products, increase penalties for violating the law's provisions, and provide health insurance coverage for tobacco treatment. AIMS AND METHODS: This study explores key informants' perceptions of intended and unintended impacts of implementation of the 2019 Massachusetts statewide law through a health equity and racial justice lens. We conducted in-depth interviews with 25 key informants from three key informant groups (public health officials and advocates, clinicians, and school staff) between March 2021 and April 2022. Using deductive codes on unintended impacts of the implementation of the law's policies, we conducted a focused analysis to identify impacts that were perceived and observed by informants from different key informant groups. RESULTS: Perceived or observed impacts of the law were identified across multiple levels by key informants and included concerns related to three broad themes: 1) intended impacts on health equity and racial justice, 2) ongoing availability of restricted products undermining the intended impact of the law, and 3) inequitable targeting by the policies and enforcement among communities of color. CONCLUSIONS: Future evaluation is needed to assess the intended and unintended impacts of implementation of the Massachusetts law to maximize the potential of the policies to reduce tobacco-related health disparities. We discuss implications and recommendations for achieving a national policy and equitable enforcement of flavored tobacco sales restrictions. IMPLICATIONS: This qualitative study among 25 key informants including public health and tobacco control advocates, clinicians, and school staff obtained perspectives of intended and unintended health equity and racial justice impacts of the 2019 Massachusetts An Act Modernizing Tobacco Control. Findings and recommendations from this study can inform monitoring efforts to assess the law's impacts in Massachusetts and the adoption of similar flavored tobacco sales restrictions and other tobacco control policies in other states to maximize the health equity benefits and minimize unintended impacts.

The Impact of Postoperative COVID-19 Infection on 30-day Outcomes of Laparoscopic Cholecystectomy.

Introduction: Preoperative Coronavirus Disease 2019 (COVID-19) infections are associated with postoperative adverse outcomes. However, there is limited data on the impact of postoperative COVID-19 infection on postoperative outcomes of common general surgery procedures.Objective: To evaluate the impact of postoperative COVID-19 diagnosis on laparoscopic cholecystectomy outcomes.Methods: Patients with symptomatic cholelithiasis, acute cholecystitis, or gallstone pancreatitis who underwent laparoscopic cholecystectomy with or without intraoperative cholangiogram were identified using the 2021 National Surgical Quality Improvement Program (NSQIP) database. Patients were categorized into two groups: patients with and without a postoperative COVID-19 diagnosis. Coarsened Exact Matching was used to match the groups based on preoperative risk factors, and outcomes were compared.Results: A total of 47,948 patients were included. In the aggregate cohort, 31% were male, and mean age was 50 years. Age, BMI, smoking, COPD, CHF, preoperative sepsis, and ASA class were significantly different between the two groups. After matching, there were no differences in characteristics. 30-day morbidity (OR = 2.7, 95% CI 1.4-5.1), pneumonia (OR = 5.0, 95% CI 1.7-15.0), DVT (OR = 8.22, 95% CI 1.0-66), reoperation (OR = 9.3, 95% CI 1.2-73.8), and readmission (OR = 4.8, 95% CI 2.3-10.1) continued to be significantly worse in the matched cohort.Conclusion: Postoperative COVID-19 infection was associated with worse outcomes after laparoscopic cholecystectomy. These findings suggest that even postoperative COVID-19 diagnosis increases the risk for adverse outcomes in patients recovering from laparoscopic cholecystectomy and may indicate that precautions should be taken and new COVID-19 infections even after surgery should be closely monitored.

Predicting Primary Care Physician Burnout From Electronic Health Record Use Measures.

OBJECTIVE: To evaluate the ability of routinely collected electronic health record (EHR) use measures to predict clinical work units at increased risk of burnout and potentially most in need of targeted interventions. METHODS: In this observational study of primary care physicians, we compiled clinical workload and EHR efficiency measures, then linked these measures to 2 years of well-being surveys (using the Stanford Professional Fulfillment Index) conducted from April 1, 2019, through October 16, 2020. Physicians were grouped into training and confirmation data sets to develop predictive models for burnout. We used gradient boosting classifier and other prediction modeling algorithms to quantify the predictive performance by the area under the receiver operating characteristics curve (AUC). RESULTS: Of 278 invited physicians from across 60 clinics, 233 (84%) completed 396 surveys. Physicians were 67% women with a median age category of 45 to 49 years. Aggregate burnout score was in the high range (≥3.325/10) on 111 of 396 (28%) surveys. Gradient boosting classifier of EHR use measures to predict burnout achieved an AUC of 0.59 (95% CI, 0.48 to 0.77) and an area under the precision-recall curve of 0.29 (95% CI, 0.20 to 0.66). Other models' confirmation set AUCs ranged from 0.56 (random forest) to 0.66 (penalized linear regression followed by dichotomization). Among the most predictive features were physician age, team member contributions to notes, and orders placed with user-defined preferences. Clinic-level aggregate measures identified the top quartile of clinics with 56% sensitivity and 85% specificity. CONCLUSION: In a sample of primary care physicians, routinely collected EHR use measures demonstrated limited ability to predict individual burnout and moderate ability to identify high-risk clinics.

Magnesium sulfate and risk of hypoxic-ischemic encephalopathy in a high-risk cohort.

BACKGROUND: Hypoxic-ischemic encephalopathy contributes to morbidity and mortality among neonates ≥36 weeks of gestation. Evidence of preventative antenatal treatment is limited. Magnesium sulfate has neuroprotective properties among preterm fetuses. Hypertensive disorders of pregnancy are a risk factor for hypoxic-ischemic encephalopathy, and magnesium sulfate is recommended for maternal seizure prophylaxis among patients with preeclampsia with severe features. OBJECTIVE: (1) Determine trends in the incidence of hypertensive disorders of pregnancy, antenatal magnesium sulfate, and hypoxic-ischemic encephalopathy; (2) evaluate the association between hypertensive disorders of pregnancy and hypoxic-ischemic encephalopathy; and (3) evaluate if, among patients with hypertensive disorders of pregnancy, the odds of hypoxic-ischemic encephalopathy is mitigated by receipt of antenatal magnesium sulfate. STUDY DESIGN: We analyzed a prospective cohort of live births ≥36 weeks of gestation between 2012 and 2018 within the California Perinatal Quality Care Collaborative registry, linked with the California Department of Health Care Access and Information files. We used Cochran-Armitage tests to assess trends in hypertensive disorders, encephalopathy diagnoses, and magnesium sulfate utilization and compared demographic factors between patients with or without hypertensive disorders of pregnancy or treatment with magnesium sulfate. Hierarchical logistic regression models were built to explore if hypertensive disorders of pregnancy were associated with any severity and moderate/severe hypoxic-ischemic encephalopathy. Separate hierarchical logistic regression models were built among those with hypertensive disorders of pregnancy to evaluate the association of magnesium sulfate with hypoxic-ischemic encephalopathy. RESULTS: Among 44,314 unique infants, the diagnosis of hypoxic-ischemic encephalopathy, maternal hypertensive disorders of pregnancy, and the use of magnesium sulfate increased over time. Compared with patients with hypertensive disorders of pregnancy alone, patients with hypertensive disorders treated with magnesium sulfate represented a high-risk population. They were more likely to be publicly insured, born between 36 and 38 weeks of gestation, be small for gestational age, have lower Apgar scores, require a higher level of resuscitation at delivery, have prolonged rupture of membranes, experience preterm labor and fetal distress, and undergo operative delivery (all P<.002). Hypertensive disorders of pregnancy were associated with hypoxic-ischemic encephalopathy (adjusted odds ratio, 1.26 [95% confidence interval, 1.13-1.40]; P<.001) and specifically moderate/severe hypoxic-ischemic encephalopathy (adjusted odds ratio, 1.26 [95% confidence interval, 1.11-1.42]; P<.001). Among patients with hypertensive disorders of pregnancy, treatment with magnesium sulfate was associated with 29% reduction in the odds of neonatal hypoxic-ischemic encephalopathy (adjusted odds ratio, 0.71 [95% confidence interval, 0.52-0.97]; P=.03) and a 37% reduction in the odds of moderate/severe neonatal hypoxic-ischemic encephalopathy (adjusted odds ratio, 0.63 [95% confidence interval, 0.42-0.94]; P=.03). CONCLUSION: Hypertensive disorders of pregnancy are associated with hypoxic-ischemic encephalopathy and, specifically, moderate/severe disease. Among people with hypertensive disorders, receipt of antenatal magnesium sulfate is associated with a significant reduction in the odds of hypoxic-ischemic encephalopathy and moderate/severe disease in a neonatal cohort admitted to neonatal intensive care unit at ≥36 weeks of gestation. The findings of this observational study cannot prove causality and are intended to generate hypotheses for future clinical trials on magnesium sulfate in term infants.

Dual-Vaping of Nicotine and Cannabis Among Adults Who Currently Use Tobacco Products in Five New England States.

INTRODUCTION: Current measures of vaping behaviors in the U.S. do not distinguish what substances participants are vaping and to what extent they are dual-vaping nicotine and cannabis. This study describes the use of new survey questions that more specifically ask whether participants who vape are vaping nicotine, cannabis, cannabidiol (CBD), or another substance. AIMS AND METHODS: Adults, who reported any past 30-day tobacco use, from five New England states participated in an online survey from April 2021 to July 2022. Participants who vaped were asked, "Have you used any of the following vape substances in the past 30 days?" with the possible responses of nicotine, cannabis, CBD, other, and "don't know." Dual use of both nicotine and cannabis was defined as the vaping of both nicotine and cannabis and/or CBD in the past 30 days, operationalized as a dichotomous outcome. Data were collected in monthly, repeated cross-sectional waves. Multinomial logistic regression was used to examine correlates of dual-vaping. RESULTS: The analytic sample included 1547 adults who reported past 30-day tobacco use (mean age 42.9 years, 62.8% female, 85.4% White, 48.5% income of less than $50 000). Over one-quarter (26.1%) reported dual-vaping in the past 30 days. Identifying as male (p = .002) and self-rated anxiety (p = .043) were associated with a higher odds of dual-vaping. CONCLUSIONS: Our findings show that a sizable proportion of a sample of New England adults who have used tobacco in the past 30 days are dual-vaping nicotine and cannabis. Adequate survey measures for assessing the vaping of multiple substances can help in better screening and characterization of health behaviors around dual-use. IMPLICATIONS: This study addresses a key gap in adequate survey measures for assessing vaping of multiple substances. We found that among adults with past 30-day tobacco use, dual-vaping was prevalent and associated with different correlates, such as self-reported anxiety and education level, compared to sole-vaping of nicotine or cannabis. Our findings may help in characterizing and targeting future population-level surveillance and intervention efforts for multiple substance use behaviors.

High-Frequency Spinal Stimulation Suppresses Microglial Kaiso-P2X7 Receptor Axis-Induced Inflammation to Alleviate Neuropathic Pain in Rats.

OBJECTIVE: Neuropathic pain poses a persistent challenge in clinical management. Neuromodulation has emerged as a last-resort therapy. Conventional spinal cord stimulation (Con SCS) often causes abnormal sensations and provides short analgesia, whereas high-frequency spinal cord stimulation (HF SCS) is a newer therapy that effectively alleviates pain without paresthesia. However, the modes of action of 10kHz HF SCS (HF10 SCS) in pain relief remain unclear. To bridge this knowledge gap, we employed preclinical models that mimic certain features of clinical SCS to explore the underlying mechanisms of HF10 SCS. Addressing these issues would provide the scientific basis for improving and evaluating the effectiveness, reliability, and practicality of different frequency SCS in clinical settings. METHODS: We established a preclinical SCS model to examine its effects in a neuropathic pain rat model. We conducted bulk and single-cell RNA sequencing in the spinal dorsal horn (SDH) to examine cellular and molecular changes under different treatments. We employed genetic manipulations through intrathecal injection of a lentiviral system to explore the SCS-mediated signaling axis in pain. Various behavioral tests were performed to evaluate pain conditions under different treatments. RESULTS: We found that HF10 SCS significantly reduces immune responses in the SDH by inactivating the Kaiso-P2X7R pathological axis in microglia, promoting long-lasting pain relief. Targeting Kaiso-P2X7R in microglia dramatically improved efficacy of Con SCS treatment, leading to reduced neuroinflammation and long-lasting pain relief. INTERPRETATION: HF10 SCS could improve the immunopathologic state in the SDH, extending its benefits beyond symptom relief. Targeting the Kaiso-P2X7R axis may enhance Con SCS therapy and offer a new strategy for pain management. ANN NEUROL 2024;95:966-983.

Does source matter? Examining the effects of health experts, friends, and social media influencers on young adult perceptions of Instagram e-cigarette education messages.

PURPOSE: Young adults' e-cigarette use is a leading public health concern. Using messages from credible sources can help improve message acceptance, yet little research has examined the role of source credibility on young adults' responses to e-cigarette education messages. METHODS: We examined the impact of source on young adults' perceptions of e-cigarette education messages and e-cigarettes. In July 2022, we conducted an experimental study using an online sample of young adults (N=459, Mage=24.6) who were randomized to one of three source conditions: expert, friend, or influencer, and viewed e-cigarette education messages. We used one-way ANOVA to estimate the association between the conditions and outcomes (perceived source credibility, message trust, curiosity, use interests, perceived message effectiveness, beliefs, harm perceptions, and intentions to refrain). RESULTS: The expert condition was associated with significantly higher perceived source credibility (vs. friend, influencer; p<0.001), message trust (vs. friend, influencer; p<0.001), and curiosity (vs. influencer; p's<0.05). CONCLUSIONS: Public health campaigns may leverage health experts to deliver e-cigarette education messages targeting young adults to improve effectiveness of the messages.

Intrinsic and extrinsic actions of human neural progenitors with SUFU inhibition promote tissue repair and functional recovery from severe spinal cord injury.

Neural progenitor cells (NPCs) derived from human pluripotent stem cells(hPSCs) provide major cell sources for repairing damaged neural circuitry and enabling axonal regeneration after spinal cord injury (SCI). However, the injury niche and inadequate intrinsic factors in the adult spinal cord restrict the therapeutic potential of transplanted NPCs. The Sonic Hedgehog protein (Shh) has crucial roles in neurodevelopment by promoting the formation of motorneurons and oligodendrocytes as well as its recently described neuroprotective features in response to the injury, indicating its essential role in neural homeostasis and tissue repair. In this study, we demonstrate that elevated SHH signaling in hNPCs by inhibiting its negative regulator, SUFU, enhanced cell survival and promoted robust neuronal differentiation with extensive axonal outgrowth, counteracting the harmful effects of the injured niche. Importantly, SUFU inhibition in NPCs exert non-cell autonomous effects on promoting survival and neurogenesis of endogenous cells and modulating the microenvironment by reducing suppressive barriers around lesion sites. The combined beneficial effects of SUFU inhibition in hNPCs resulted in the effective reconstruction of neuronal connectivity with the host and corticospinal regeneration, significantly improving neurobehavioral recovery in recipient animals. These results demonstrate that SUFU inhibition confers hNPCs with potent therapeutic potential to overcome extrinsic and intrinsic barriers in transplantation treatments for SCI.

Racial and Ethnic Composition of Populations Served by Freestanding Children's Hospitals and Disparities in Outcomes of Pediatric Lupus.

OBJECTIVE: Health disparities may be driven by hospital-level factors. We assessed whether racial and ethnic composition of populations hospitals serve explain or modify disparities in hospital outcomes of children with systemic lupus erythematosus (SLE). METHODS: In this retrospective cohort study of patients 5 to 26 years old with SLE at 47 children's hospitals in the Pediatric Health Information System (2006-2021), race and ethnicity were assessed at the patient level and hospital level (proportion of total admissions composed of Black or Hispanic patients, respectively). Outcomes included intensive care unit (ICU) admission or adverse renal outcome (end-stage renal disease, dialysis, or transplant) during follow-up. We estimated racial and ethnic disparities, adjusted or stratified by hospital racial or ethnic composition. RESULTS: Of 8,125 patients with SLE, 2,293 (28%) required ICU admission, and 698 (9%) had an adverse renal outcome. Black and non-Hispanic White disparities in ICU admission were observed only at hospitals serving higher proportions of Black patients (odds ratio [OR] 1.29, 95% confidence interval [95% CI] 1.04-1.59 vs OR 1.07, 95% CI 0.83-1.38). Larger Black and non-Hispanic White disparities in adverse renal outcomes were observed at hospitals with higher Black racial composition (OR 2.0, 95% CI 1.4-2.8 vs OR 1.7, 95% CI 1.1-2.4). Conversely, Hispanic versus non-Hispanic disparities in renal outcomes persisted after adjustment for hospital-reported Hispanic ethnic composition but were observed only at hospitals with lower proportions of Hispanic patients. CONCLUSION: Worse Black and White disparities in SLE outcomes are observed at children's hospitals serving more Black children, whereas distinct patterns are observed for Hispanic and non-Hispanic disparities. Reporting of hospital characteristics related to populations served is needed to identify modifiable drivers of hospital-level variation.
