"I Like the Vibes it Gives": Adolescent Perspectives on Cannabis Billboards and Print Advertising in Nevada.

An influx of laws permitting recreational cannabis sales in the US has allowed for increased advertising. The purpose of this study was to describe how adolescents perceive outdoor and print cannabis advertising and to identify aspects of advertising that are appealing or eye-catching, focusing on five themes: price promotion, sex appeal, wellness, party, and text-only. We recruited adolescents ages 11-17 to participate in seven focus groups (44 participants) from 2019 to 2020. Participants viewed cannabis advertisements and responses were summarized using deductive thematic analysis. The party-themed advertisements were the most salient to participants, who desired to emulate the behaviors shown. Participants favored ads featuring young people and containing multiple colors. Participants disliked advertisements perceived to portray misleading or contradictory messages, such as the promotion of physical activity or use of sex appeal, and ads perceived to lack authenticity. Identification of youth appealing features can help inform cannabis advertising regulations.

The effect of cystic echinococcosis (hydatid disease) on carcase weight in cattle in eastern Australia.

Cystic echinococcosis is caused by the zoonotic tapeworm Echinococcus granulosus. There has been ongoing controversy over whether it causes weight loss in cattle. Recently implemented recording of comorbidities at processors has provided opportunity to investigate this effect. Using prevalence-based observational data from 1,648,049 adult cattle processed in seven states and territories in Australia (2019-2022), we explored associations between carcase weight, hydatid cysts, comorbidities, sex, age, and region. Linear mixed-effect regression models estimated the effect of cystic echinococcosis on carcase weight, guided by directed acyclic graphs to reduce bias. The highest, previously unreported, prevalence was in the southeast Queensland region. The estimated effect of cystic echinococcosis cysts on carcase weight ranged from a gain of 0.32 kg/carcase (standard error [se] 0.58 kg; two-tooth 2022) to a loss of -5.45 kg/carcase (se 0.63 kg; six-tooth 2019) with most point estimates (11/16) between 0 and -2.5 kg across all cattle grouped by year and dentition. This effect size would be practically undetectable in live cattle which is an important finding; cattle producers are unlikely to observe increased productivity through weight gain from cystic echinococcosis prevention in cattle, and awareness to strengthen prevention in domestic dogs around cattle properties to reduce human risk remains a public health focus.

Randomized Trial on Expectations and Pain Control Advancement in Surgery: The REPAIR Study.

IMPORTANCE: Following standardized preoperative education and adoption of shared decision making positively affects postoperative narcotic practices. OBJECTIVES: The aim of this study was to assess the impact of patient-centered preoperative education and shared decision making on the quantities of postoperative narcotics prescribed and consumed after urogynecologic surgery. STUDY DESIGN: Women undergoing urogynecologic surgery were randomized to "standard" (standard preoperative education, standard narcotic quantities at discharge) or "patient-centered" (patient-informed preoperative education, choice of narcotic quantities at discharge) groups. At discharge, the "standard" group received 30 (major surgery) or 12 (minor surgery) pills of 5-mg oxycodone. The "patient-centered" group chose 0 to 30 (major surgery) or 0 to 12 (minor surgery) pills. Outcomes included postoperative narcotics consumed and unused. Other outcomes included patient satisfaction/preparedness, return to activity, and pain interference. An intention-to-treat analysis was performed. RESULTS: The study enrolled 174 women; 154 were randomized and completed the major outcomes of interest (78 in the standard group, 76 in the patient-centered group). Narcotic consumption did not differ between groups (standard group: median of 3.5 pills, interquartile range [IQR] of [0, 8.25]; patient centered: median of 2, IQR of [0, 9.75]; P = 0.627). The patient-centered group had fewer narcotics prescribed ( P < 0.001) and unused ( P < 0.001), and chose a median of 20 pills (IQR [10, 30]) after a major surgical procedure and 12 pills (IQR [6, 12]) after a minor surgical procedure, with fewer unused narcotics (median difference, 9 pills; 95% confidence interval, 5-13; P < 0.001). There were no differences between groups' return to function, pain interference, and preparedness or satisfaction ( P > 0.05). CONCLUSIONS: Patient-centered education did not decrease narcotic consumption. Shared decision making did decrease prescribed and unused narcotics. Shared decision making in narcotic prescribing is feasible and may improve postoperative prescribing practices.

Relational and physical aggression in preschool-age children: Associations with teacher, parent, sibling, and peer relationship quality.

Early childhood relationships with teachers, parents, siblings, and peers are foundational factors for later social functioning. High rates of childhood aggression have been associated with negative developmental consequences, however, the associations between child aggression on the quality of these formative relationships have not been studied extensively. In a sample of young children attending preschool (N = 114, Mage = 46.27 months, SD = 9.94, 40% girls), this study investigated associations between early childhood relational and physical aggression and the quality of concurrent teacher-child and parent-child closeness and conflict, sibling relationship quality, and positive peer interactions and peer rejection. Early childhood relational and physical aggression was associated with negative teacher-child relationships, and this was true for boys and girls. Differential patterns of prediction were found for relational and physical aggression on the other relationship variables. Relational aggression strongly predicted more positive peer interactions, whereas physical aggression predicted fewer positive peer interactions and greater peer rejection. Early childhood relational aggression predicted higher levels of teacher-child closeness, whereas physical aggression predicted lower levels of teacher-child closeness and fewer positive sibling interactions. These findings challenge common perceptions that aggression is negatively associated with relationship quality. Notably, relational aggression relative to physical aggression may be associated with some favorable relationship outcomes. We did not find support for an additive model of aggression whereby children who were both relationally and physically aggressive (co-morbid) were at higher risk for negative relationship quality. Implications of these findings for future research and prevention and intervention are discussed.

Association of Maternal Comorbidity Burden With Cesarean Birth Rate Among Nulliparous, Term, Singleton, Vertex Pregnancies.

IMPORTANCE: Cesarean birth rate among nulliparous, term, singleton, vertex (NTSV) pregnancies is a standard quality measure in obstetrical care. There are limited data on how the number and type of preexisting conditions affect mode of delivery among primigravidae, and it is also uncertain how maternal comorbidity burden differs across racial and ethnic groups and whether this helps to explain disparities in the NTSV cesarean birth rate. OBJECTIVE: To determine the association between obstetric comorbidity index (OB-CMI) score and cesarean delivery among NTSV pregnancies and to evaluate whether disparities in mode of delivery exist based on race and ethnicity group after adjusting for covariate factors. DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study of deliveries between January 2019 and December 2021 took place across 7 hospitals within a large academic health system in New York and included all NTSV pregnancies identified in the electronic medical record system. Exclusion criteria were fetal demise and contraindication to labor. EXPOSURE: The OB-CMI score. Covariate factors assessed included race and ethnicity group (American Indian or Alaska Native, Asian or Pacific Islander, Hispanic, non-Hispanic Black, non-Hispanic White, other or multiracial, and declined or unknown), public health insurance, and preferred language. MAIN OUTCOME AND MEASURES: Cesarean delivery. RESULTS: A total of 30 253 patients (mean [SD] age, 29.8 [5.4] years; 100% female) were included. Non-Hispanic White patients constituted the largest race and ethnicity group (43.7%), followed by Hispanic patients (16.2%), Asian or Pacific Islander patients (14.6%), and non-Hispanic Black patients (12.2%). The overall NTSV cesarean birth rate was 28.5% (n = 8632); the rate increased from 22.1% among patients with an OB-CMI score of 0 to greater than 55.0% when OB-CMI scores were 7 or higher. On multivariable mixed-effects logistic regression modeling, there was a statistically significant association between OB-CMI score group and cesarean delivery; each successive OB-CMI score group had an increased risk. Patients with an OB-CMI score of 4 or higher had more than 3 times greater odds of a cesarean birth (adjusted odds ratio, 3.14; 95% CI, 2.90-3.40) than those with an OB-CMI score of 0. Compared with non-Hispanic White patients, nearly all other race and ethnicity groups were at increased risk for cesarean delivery, and non-Hispanic Black patients were at highest risk (adjusted odds ratio, 1.43; 95% CI, 1.31-1.55). CONCLUSIONS AND RELEVANCE: In this cross-sectional study of patients with NTSV pregnancies, OB-CMI score was positively associated with cesarean birth. Racial and ethnic disparities in this metric were observed. Although differences in the prevalence of preexisting conditions were seen across groups, this did not fully explain variation in cesarean delivery rates, suggesting that unmeasured clinical or nonclinical factors may have influenced the outcome.

Enhanced Neuron Growth and Electrical Activity by a Supramolecular Netrin-1 Mimetic Nanofiber.

Neurotrophic factors are essential not only for guiding the organization of the developing nervous system but also for supporting the survival and growth of neurons after traumatic injury. In the central nervous system (CNS), inhibitory factors and the formation of a glial scar after injury hinder the functional recovery of neurons, requiring exogenous therapies to promote regeneration. Netrin-1, a neurotrophic factor, can initiate axon guidance, outgrowth, and branching, as well as synaptogenesis, through activation of deleted in colorectal cancer (DCC) receptors. We report here the development of a nanofiber-shaped supramolecular mimetic of netrin-1 with monomers that incorporate a cyclic peptide sequence as the bioactive component. The mimetic structure was found to activate the DCC receptor in primary cortical neurons using low molar ratios of the bioactive comonomer. The supramolecular nanofibers enhanced neurite outgrowth and upregulated maturation as well as pre- and postsynaptic markers over time, resulting in differences in electrical activity similar to neurons treated with the recombinant netrin-1 protein. The results suggest the possibility of using the supramolecular structure as a therapeutic to promote regenerative bioactivity in CNS injuries.

Normative Beliefs and Aggression: The Mediating Roles of Empathy and Anger.

This study examined a two-mediator model with both empathy and anger as mediators in the association between children's normative beliefs about aggression and forms (relational and physical) and functions (reactive and proactive) of aggressive behavior. Ninety-eight children (54% males, Mage=46.21months, SD = 8.84months) reported their approval of relationally and physically aggressive behaviors depicted in iconic (animation) and enactive (toy figurines) hypothetical scenarios. Children's aggression, empathy and anger were measured using teacher reports. No main effects of normative beliefs about aggression on the corresponding aggressive behavior were found. Normative beliefs about aggression were negatively associated with empathy and empathy was significantly associated with relational aggression, suggesting that developing social emotional processes mediate the relation between social cognitions and aggression. Anger was associated with aggression, but not normative beliefs about aggression. The findings provide support for the distinction between subtypes of aggressive behavior in young children and the developing social-cognitive and affective processes that influence these behaviors.

Hypertensive disorders of pregnancy and severe acute respiratory syndrome coronavirus-2 infection.

OBJECTIVES: We aimed to determine whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in pregnancy is associated with an increased risk of hypertensive disorders of pregnancy (HDP). METHODS: A multicenter retrospective cohort study of all pregnant patients who had SARS-CoV-2 testing and delivered in a large health system between March 2020 and March 2021. Cases were stratified into two groups: patients who tested positive for SARS-CoV-2 during pregnancy vs. patients who tested negative. The primary outcome of HDP, defined as a composite of gestational hypertension, preeclampsia, hemolysis, elevated liver enzymes, and low platelet count syndrome (HELLP Syndrome), and eclampsia by standard criteria, was compared between the two groups. Statistical analysis included multivariable logistic regression to adjust for potential confounders such as maternal demographics and comorbidities. Patient ZIP codes were linked to neighborhood-level data from the US Census Bureau's American Community Survey. RESULTS: Of the 22,438 patients included, 1,653 (7.4%) tested positive for SARS-CoV-2 infection. Baseline demographics such as age, body mass index, race, ethnicity, insurance type, neighborhood-built environmental and socioeconomic status, nulliparity, and pregestational diabetes differed significantly between the two groups. SARS-CoV- 2 infection in pregnancy was not associated with an increased risk of HDP compared to those without infection (14.9 vs. 14.8%; aOR 1.06 95% CI 0.90-1.24). CONCLUSIONS: In this large cohort that included a universally-tested population with several socioeconomic indicators, SARS-CoV-2 infection in pregnancy was not associated with an increased risk of HDP.

Biomimetic Extracellular Scaffolds by Microfluidic Superstructuring of Nanofibers.

The extracellular matrix is a dynamic framework bearing chemical and morphological cues that support many cellular functions, and artificial analogs with well-defined chemistry are of great interest for biomedical applications. Herein, we describe hierarchical, extracellular-matrix-mimetic microgels, termed "superbundles" (SBs) composed of peptide amphiphile (PA) supramolecular nanofiber networks created using flow-focusing microfluidic devices. We explore the effects of altered flow rate ratio and PA concentration on the ability to create SBs and develop design rules for producing SBs with both cationic and anionic PA nanofibers and gelators. We demonstrate the morphological similarities of SBs to decellularized extracellular matrices and showcase their ability to encapsulate and retain proteinaceous cargos with a wide variety of isoelectric points. Finally, we demonstrate that the novel SB morphology does not affect the well-established biocompatibility of PA gels.

Artificial extracellular matrix scaffolds of mobile molecules enhance maturation of human stem cell-derived neurons.

Human induced pluripotent stem cell (hiPSC) technologies offer a unique resource for modeling neurological diseases. However, iPSC models are fraught with technical limitations including abnormal aggregation and inefficient maturation of differentiated neurons. These problems are in part due to the absence of synergistic cues of the native extracellular matrix (ECM). We report on the use of three artificial ECMs based on peptide amphiphile (PA) supramolecular nanofibers. All nanofibers display the laminin-derived IKVAV signal on their surface but differ in the nature of their non-bioactive domains. We find that nanofibers with greater intensity of internal supramolecular motion have enhanced bioactivity toward hiPSC-derived motor and cortical neurons. Proteomic, biochemical, and functional assays reveal that highly mobile PA scaffolds caused enhanced ß1-integrin pathway activation, reduced aggregation, increased arborization, and matured electrophysiological activity of neurons. Our work highlights the importance of designing biomimetic ECMs to study the development, function, and dysfunction of human neurons.

Environmental and health risks of perovskite solar modules: Case for better test standards and risk mitigation solutions.

Perovskite solar cells (PSCs) promise high efficiencies and low manufacturing costs. Most formulations, however, contain lead, which raises health and environmental concerns. In this review, we use a risk assessment approach to identify and evaluate the technology risks to the environment and human health. We analyze the risks by following the technology from production to transportation to installation to disposal and examine existing environmental and safety regulations in each context. We review published data from leaching and air emissions testing and highlight gaps in current knowledge and a need for more standardization. Methods to avoid lead release through introduction of absorbing materials or use of alternative PSC formulations are reviewed. We conclude with the recommendation to develop recycling programs for PSCs and further standardized testing to understand risks related to leaching and fires.

Impairments to executive function in emerging adults with Huntington disease.

BACKGROUND AND OBJECTIVES: The clinical diagnosis of Huntington disease (HD) is typically made once motor symptoms and chorea are evident. Recent reports highlight the onset of cognitive and psychiatric symptoms before motor manifestations. These findings support further investigations of cognitive function across the lifespan of HD sufferers. METHODS: To assess cognitive symptoms in the developing brain, we administered assessments from the National Institutes of Health Toolbox Cognitive Battery, an age-appropriate cognitive assessment with population norms, to a cohort of children, adolescents and young adults with (gene-expanded; GE) and without (gene-not-expanded; GNE) the trinucleotide cytosine, adenine, guanine (CAG) expansion in the Huntingtin gene. These five assessments that focus on executive function are well validated and form a composite score, with population norms. We modelled these scores across age, and CAP score to estimate the slope of progression, comparing these results to motor symptoms. RESULTS: We find significant deficits in the composite measure of executive function in GE compared with GNE participants. GE participant performance on working memory was significantly lower compared with GNE participants. Modelling these results over age suggests that these deficits occur as early as 18 years of age, long before motor manifestations of HD. CONCLUSIONS: This work provides strong evidence that impairments in executive function occur as early as the second decade of life, well before anticipated motor onset. Future investigations should delineate whether these impairments in executive function are due to abnormalities in neurodevelopment or early sequelae of a neurodegenerative process.

Problematic media use in early childhood: The role of parent-child relationships and parental wellbeing in families in New Zealand and the United States.

Problematic media use (PMU) during early childhood has the potential to interfere with the healthy functioning of family systems and may be associated with significant long-term problems for the child. However, we know very little about what contributes to early childhood PMU, particularly in the family context. We examine parenting factors as correlates of child PMU in two studies, from two different countries, using two different methods. Study 1 (N=93, Mage=45.3months, SD=10.15, 58%males, 87%mothers) investigated the concurrent role of self-reported parental burnout and parent-child conflict and closeness as correlates of child PMU in an early childhood sample in New Zealand. Study 2 (N=269, Mage=41.17months, SD=3.06 months, 49%males, 95%mothers) investigated observed parental warmth and harsh criticism as predictors of concurrent and longitudinal PMU in an early childhood sample in the United States. Together, findings showed that in both countries approximately 22-25% of young children show symptoms of PMU. After controlling for parent's PMU, parent-child conflict, warmth and parental burnout were not associated with child PMU. Low levels of parent-child closeness and parent's use of harsh criticism were predictive of child PMU. The findings advance our understanding of some of the parenting factors that influence the development of PMU in young children.

Nonadherence to treatment protocol for severe hypertension in pregnancy.

BACKGROUND: Hypertensive disorders of pregnancy are one of the leading causes of maternal mortality and severe morbidity. The American College of Obstetricians and Gynecologists recommends treatment of persistent severe hypertension because this has been shown to improve overall outcomes. Treatment remains inconsistent and may be influenced by patient-level sociodemographic and clinical characteristics. OBJECTIVE: This study aimed to identify which factors are associated with nonadherence to an institutional protocol for the treatment of severe hypertension in pregnancy. STUDY DESIGN: Retrospective cohort study of patients who had persistent severe hypertension (≥2 systolic blood pressures ≥160 mm Hg and/or diastolic blood pressures >110 mm Hg between 15 and 60 minutes apart) during their delivery hospitalization in 3 hospitals within an integrated health system from February 1, 2018 to March 1, 2020. Adherence to an institutional protocol was defined as receiving antihypertensive medication within 1 hour of a second severe blood pressure measurement. Demographic information, medical comorbidities, and delivery hospitalization characteristics were compared between women who received treatment based on institutional protocol and those who did not. Patient zone improvement plan codes were linked to neighborhood-level data from the US Census Bureau's American Community Survey to extract socioeconomic characteristics. A multivariable logistic regression was performed to evaluate factors associated with delayed treatment while adjusting for potential confounders. RESULTS: Of the 996 patients included, 449 (45%) received treatment within 60 minutes and 547 (55%) did not. Having an elevated, nonsevere range blood pressure (adjusted odds ratio, 0.55; 95% confidence interval, 0.38-0.79) or a severe range blood pressure (adjusted odds ratio, 0.25; 95% confidence interval, 0.16-0.38) on admission, persistent severe hypertension ≥1 hour before or after delivery (adjusted odds ratio, 0.27; 95% confidence interval, 0.27-0.45), and chronic hypertension (adjusted odds ratio, 0.58; 95% confidence interval, 0.37-0.93) were associated with timely treatment. Hospital site (adjusted odds ratio, 1.97; 95% confidence interval, 1.18-3.28) and increasing gestational age (adjusted odds ratio, 1.14; 95% confidence interval, 1.07-1.21) were associated with nonadherence to treatment protocol. A subanalysis evaluating treatment in 344 (35%) patients who had a nonelevated blood pressure on admission showed that White race, persistent severe hypertension within 1 hour of delivery, increasing gestational age, body mass index, twin gestation, preferred language other than English or Spanish, and a higher neighborhood unemployment rate were associated with nonadherence to treatment protocol. CONCLUSION: Several factors were associated with nonadherence to an institutional protocol for treatment of persistent severe hypertension. Provider bias may impact whether treatment is executed or not. Awareness of these risk factors may improve timely administration of antihypertensive medication in pregnant and postpartum patients.

Microgliosis and neuronal proteinopathy in brain persist beyond viral clearance in SARS-CoV-2 hamster model.

BACKGROUND: Neurological symptoms such as cognitive decline and depression contribute substantially to post-COVID-19 syndrome, defined as lasting symptoms several weeks after initial SARS-CoV-2 infection. The pathogenesis is still elusive, which hampers appropriate treatment. Neuroinflammatory responses and neurodegenerative processes may occur in absence of overt neuroinvasion. METHODS: Here we determined whether intranasal SARS-CoV-2 infection in male and female syrian golden hamsters results in persistent brain pathology. Brains 3 (symptomatic) or 14 days (viral clearance) post infection versus mock (n = 10 each) were immunohistochemically analyzed for viral protein, neuroinflammatory response and accumulation of tau, hyperphosphorylated tau and alpha-synuclein protein. FINDINGS: Viral protein in the nasal cavity led to pronounced microglia activation in the olfactory bulb beyond viral clearance. Cortical but not hippocampal neurons accumulated hyperphosphorylated tau and alpha-synuclein, in the absence of overt inflammation and neurodegeneration. Importantly, not all brain regions were affected, which is in line with selective vulnerability. INTERPRETATION: Thus, despite the absence of virus in brain, neurons develop signatures of proteinopathies that may contribute to progressive neuronal dysfunction. Further in depth analysis of this important mechanism is required.

Severe maternal morbidity in pregnant patients with SARS-CoV-2 infection.

BACKGROUND: Although the increased risk for severe illness and adverse pregnancy outcomes associated with SARS-CoV-2 infection during pregnancy is well described, the association of infection with severe maternal morbidity has not been well characterized. OBJECTIVE: This study aimed to evaluate the risk for severe maternal morbidity associated with SARS-CoV-2 infection during pregnancy. STUDY DESIGN: This was a multicenter retrospective cohort study of all pregnant patients who had a SARS-CoV-2 test done and who delivered in a New York health system between March 1, 2020 and March 1, 2021. Patients with missing test results were excluded. The primary outcome of severe maternal morbidity, derived from the American College of Obstetricians and Gynecologists and the Society for Maternal-Fetal Medicine example list of diagnoses and complications, was compared between the following 2 groups: patients who tested positive for SARS-CoV-2 during pregnancy and patients who tested negative. Secondary outcomes included subgroups of severe maternal morbidity. Multivariable logistic regression was used to adjust for potential confounders such as maternal demographics, neighborhood socioeconomic status, hospital location, and pregnancy-related complications. A subanalysis was performed to determine if the risk for severe obstetrical hemorrhage and hypertension-associated or neurologic morbidity differed based on the timing of SARS-CoV-2 infection between those who tested positive for SARS-CoV-2 at their delivery hospitalization (ie, active infection) and those who tested positive during pregnancy but negative at their delivery hospitalization (ie, resolved infection). RESULTS: Of the 22,483 patients included, 1653 (7.4%) tested positive for SARS-CoV-2 infection. Patients with SARS-CoV-2 infection were more commonly Black, multiracial, Hispanic, non-English speaking, used Medicaid insurance, were multiparous, and from neighborhoods with a lower socioeconomic status. Patients with SARS-CoV-2 infection were at an increased risk for severe maternal morbidity when compared with those without infection (9.3 vs 6.5%; adjusted odds ratio, 1.52; 95% confidence interval, 1.21-1.88). Patients with SARS-CoV-2 infection were also at an increased risk for severe obstetrical hemorrhage (1.1% vs 0.5%; adjusted odds ratio, 1.78; 95% confidence interval, 1.04-2.88), pulmonary morbidity (2.0% vs 0.5%; adjusted odds ratio, 3.90; 95% confidence interval, 2.52-5.89), and intensive care unit admission (1.8% vs 0.5%; adjusted odds ratio, 3.29; 95% confidence interval, 2.09-5.04) when compared with those without infection. The risk for hypertension-associated or neurologic morbidity was similar between the 2 groups. The timing of SARS-CoV-2 infection (whether active or resolved at time of delivery) was not associated with the risk for severe obstetrical hemorrhage or hypertension-associated or neurologic morbidity when compared with those without infection. CONCLUSION: SARS-CoV-2 infection during pregnancy was associated with an increased risk for severe maternal morbidity, severe obstetrical hemorrhage, pulmonary morbidity, and intensive care unit admission. These data highlight the need for obstetrical unit preparedness in caring for patients with SARS-CoV-2 infection, continued public health efforts aimed at minimizing the risk for infection, and support in including this select population in investigational therapy and vaccine trials.

Adverse childhood experiences and past 30-day cannabis use among middle and high school students: The protective influence of families and schools.

Exposure to adverse childhood experiences (ACEs) is a risk factor for adolescent cannabis use (CU). We explored whether family communication and school connectedness can offer direct protection (the compensatory model of resiliency) or moderating protection (the protective factors model of resiliency). Using cluster random sampling, a Youth Risk Behavior Survey (YRBS) was conducted with 5,341 middle school and 4,980 high school students in 2019. Generalized estimating equations were used to estimate whether family communication and school connectedness offered independent direct protection (multiple regression) or moderating protection (multiplicative interaction) in the relationship between ACEs and past 30-day CU. Adjusted prevalence ratios (APR) and 95% confidence intervals (95% CI) were calculated. There was a graded relationship between ACEs and past 30-day CU for all students that was particularly strong among middle school students: 1 ACE (APR = 2.37, 95% CI = 2.16, 2.62), 2 ACEs (APR = 2.89, 95% CI = 2.60, 3.23), 3 ACEs (APR = 5.30, 95% CI = 4.75, 5.90), 4 + ACEs (APR = 7.86, 95% CI = 7.13, 8.67). Results supported the compensatory model of resiliency with both family communication (middle school APR = 0.90, 95% CI = 0.88, 0.93; high school APR = 0.90, 95% CI = 0.87, 0.93) and school connectedness (middle school APR = 0.76, 95% CI = 0.72, 0.79; high school APR = 0.72, 95% CI = 0.68, 0.77) demonstrating a direct, independent protective relationship with past 30-day CU. There was no consistent evidence supporting the protective factors resiliency model.

Inhibitory control, working memory and coping with stress: Associations with symptoms of anxiety and depression in adults with Huntington's disease.

OBJECTIVE: Huntington's disease (HD) is an autosomal dominant neurodegenerative disease characterized by neuropsychiatric symptoms (e.g., anxiety and depression), where individuals suffer high levels of stress from the social, physical, and cognitive burden of the disease. The present study examined two factors associated with increased risk for symptoms of anxiety and depression: executive function skills (inhibitory control/attention and working memory) and skills to cope with stress. METHOD: Adults with HD completed the NIH Toolbox measures of inhibitory control/attention and working memory, as well as self-report measures of coping with HD-related stress and symptoms of anxiety and depression. Path analyses were used to test direct and indirect associations among the subtypes of executive functioning, coping, and symptoms. RESULTS: No significant associations were found in the full sample (n = 47), due to a significant portion of the sample with very low executive function abilities. Additional analyses were conducted on a subset of the sample (participants in the top three quartiles on both measures of executive functioning, n = 32). Significant indirect associations emerged among inhibitory control/attention skills, secondary control coping (e.g., acceptance and reappraisal), and symptoms of anxiety and depression in the subsample. Higher inhibitory control/attention skills were associated with greater use of secondary control coping, and greater use of these coping skills was related to lower symptoms of anxiety and depression. No direct or indirect associations were found among working memory skills, coping, and symptoms of anxiety and depression. CONCLUSIONS: Implications for interventions to enhance executive function and coping skills in adults with HD are highlighted. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
