Abstract
Study objectives
The main aim of this study was to estimate the association between sleep deficiency in adolescence and subsequent prescription opioid misuse in adulthood using United States ...nationally representative longitudinal data.
Methods
Self-reported data captured in the National Longitudinal Study of Adolescent to Adult Health at baseline (Wave 1; mean age = 16 years) and 12 year follow-up (Wave 4; mean age = 29 years). Participants (n = 12,213) reported on four measures of sleep during adolescence (Wave 1) and on lifetime prescription opioid misuse during adulthood (Wave 4). Associations between adolescent sleep and adult opioid misuse were estimated using multivariate logistic regression analysis controlling for sociodemographics, chronic pain, mental health, childhood adverse events, and a history of substance use.
Results
During adolescence, 59.2% of participants reported sleep deficiency. Prospectively, adolescents reporting not getting enough sleep, chronic unrestful sleep, and insomnia were associated with an increased risk for prescription opioid misuse (adjusted odds ratios OR = 1.2, p < 0.005 for all three variables). Short sleep duration was not associated with opioid misuse.
Conclusion
This is the first study to longitudinally link sleep deficiency as an independent risk factor for the development of prescription opioid misuse. Sleep deficiency could be a driver of the opioid crisis affecting young people in the United States. Future studies should determine whether early and targeted sleep interventions may decrease risk for opioid misuse in high-risk patients prescribed opioids for pain.
To assess the oft-perceived protective relationship between women's asset ownership and experience of intimate partner violence (IPV) in the previous 12 months.
We used international survey data from ...women aged 15 to 49 years from 28 Demographic and Health Surveys (2010-2014) to examine the association between owning assets and experience of recent IPV, matching on household wealth by using multivariate probit models. Matching methods helped to account for the higher probability that women in wealthier households also have a higher likelihood of owning assets.
Asset ownership of any type was negatively associated with IPV in 3 countries, positively associated in 5 countries, and had no significant relationship in 20 countries (P < .10). Disaggregation by asset type, sole or joint ownership, women's age, and community level of women's asset ownership similarly showed no conclusive patterns.
Results suggest that the relationship between women's asset ownership and IPV is highly context specific. Additional methodologies and data are needed to identify causality, and to understand how asset ownership differs from other types of women's economic empowerment.
Limited research has examined presurgical risk factors for poor outcomes in children after major surgery. This longitudinal study examined presurgical psychosocial and behavioral factors as ...predictors of acute postsurgical pain intensity and health-related quality of life (HRQOL) in children 2 weeks after major surgery. Sixty children aged 10 to 18 years, 66.7% female, and their parent/guardian participated in the study. Children underwent baseline assessment of pain (daily electronic diary), HRQOL, sleep (actigraphy), and psychosocial factors (anxiety, pain catastrophizing). Caregivers reported on parental pain catastrophizing. Longitudinal follow-up assessment of pain and HRQOL was conducted at home 2 weeks after surgery. Regression analyses adjusting for baseline pain revealed that presurgery sleep duration (β = -.26, P < .05) and parental pain catastrophizing (β = .28, P < .05) were significantly associated with mean pain intensity reported by children 2 weeks after surgery, with shorter presurgery sleep duration and greater parental catastrophizing about child pain predicting greater pain intensity. Adjusting for baseline HRQOL, presurgery child state anxiety (β = -.29, P < .05) was significantly associated with HRQOL at 2 weeks, with greater anxiety predicting poorer HRQOL after surgery. In conclusion, child anxiety, parental pain catastrophizing, and sleep patterns are potentially modifiable factors that predict poor outcomes in children after major surgery.
This study addresses an important gap in literature, examining presurgical risk factors for poorer acute postsurgical outcomes in children undergoing major surgery. Knowledge of these factors will enable presurgical identification of children at risk for poorer outcomes and guide further research developing prevention and intervention strategies for these children.
Around 4 million children undergo inpatient surgery in the United States each year, however little is known about the impact of surgery and postoperative pain on children's health-related quality of ...life (HRQOL) during the weeks and months after surgery. We measured pain and HRQOL in a large, heterogeneous pediatric postsurgical population from baseline to 1-month follow-up. Over a 20-month period, parents of 915 children age 2 to 18 years (mean = 9.6 years), 50% male, 56% white, admitted to surgical services at a children's hospital enrolled in the study. Parent participants reported on sociodemographics, child HRQOL, and pain characteristics at baseline and 1 month after discharge. Although most of the children recovered to baseline by 1 month after hospital discharge, 23% of children had a significant decline in HRQOL. Logistic regression analyses found that increasing child age (odds ratio = 2.1 for age 13-18 years) and the presence of moderate-severe postsurgical pain at 1 month (odds ratio = 5.7) were significantly associated with deterioration in HRQOL from baseline to 1-month follow-up (P < .05 for each variable). Although HRQOL returns to the baseline level for most children, a sizeable proportion have significant deterioration in HRQOL associated with continued postsurgical pain at 1 month after hospital discharge from surgery.
This study addresses an important gap in the literature, examining pain and health-related quality of life in a broad population of children undergoing a wide range of inpatient surgeries. Evaluation of inpatient health services from a patient and family perspective is essential in evaluating outcomes of surgical care.
Sickle cell disease (SCD) is characterized by severe acute pain episodes as well as risk for chronic pain. Digital delivery of SCD pain self-management support may enhance pain self-management skills ...and accessibility for youth. However, little is known about how youth with SCD and their caregivers engage with digital health programs. iCanCope with pain is a digital pain self-management platform adapted for youth with SCD and caregivers through a user-centered design approach. The program was delivered via a website (separate versions for youth and caregiver) and mobile app (youth only). We aimed to characterize patterns of user engagement with the iCanCope with SCD program among youth with SCD and their caregivers. A randomized controlled trial was completed across multiple North American SCD clinics. Eligible youth were aged 12-18 years, diagnosed with SCD, English-speaking, and experiencing moderate-to-severe pain interference. Eligible caregivers were English-speaking with a child enrolled in the study. Dyads were randomized to receive the iCanCope intervention or attention-control education for 8-12 weeks. This report focused on engagement among dyads who received the intervention. User-level analytics were captured. Individual interviews were conducted with 20% of dyads. Descriptive statistics characterized quantitative engagement. Content analysis summarized qualitative interview data. Exploratory analysis tested the hypothesis that caregiver engagement would be positively associated with child engagement. The cohort included primarily female (60% 34/57 of youth; 91% 49/56 of caregivers) and Black (>90% of youth 53/57 and caregivers 50/56) participants. Among 56 dyads given program access, differential usage patterns were observed: both the youth and caregiver engaged (16/56, 29%), only the youth engaged (24/56, 43%), only the caregiver engaged (1/56, 2%), and neither individual engaged (16/56, 29%). While most youth engaged with the program (40/57, 70%), most caregivers did not (39/56, 70%). Youth were more likely to engage with the app than the website (85% 34/57 versus 68% 23/57), and the most popular content categories were goal setting, program introduction, and symptom history. Among caregivers, program introduction, behavioral plans, and goal setting were the most popular content areas. As hypothesized, there was a moderate positive association between caregiver and child engagement (χsup.2 sub.1=6.6; P=.01; ϕ=0.34). Interviews revealed that most dyads would continue to use the program (11/12, 92%) and recommend it to others (10/12, 83%). The reasons for app versus website preference among youth were ease of use, acceptable time commitment, and interactivity. Barriers to caregiver engagement included high time burden and limited perceived relevance of content. This is one of the first studies to apply digital health analytics to characterize patterns of engagement with SCD self-management among youth and caregivers. The findings will be used to optimize the iCanCope with SCD program prior to release.
Severe acute and chronic pain are the most common complications of sickle cell disease (SCD). Pain results in disability, psychosocial distress, repeated clinic visits/hospitalizations, and ...significant healthcare costs. Psychosocial pain interventions that teach cognitive and behavioral strategies for managing pain have been effective in other adolescent populations when delivered in person or through digital technologies. Our aim was to conduct a multisite, randomized, controlled trial to improve pain and coping in youth aged 12 to 18 years with SCD using a digital cognitive-behavioral therapy program (iCanCope with Sickle Cell Disease; iCC-SCD) vs Education control. We enrolled 137 participants (ages 12-18 years, 59% female) and analyzed 111 adolescents (107 caregivers), 54 randomized to Education control and 57 randomized to iCC-SCD. Ninety-two percent of youth completed posttreatment assessments and 88% completed 6-month follow-up. There was a significant effect of treatment group (iCC-SCD vs Education) on reduction in average pain intensity from baseline to 6-month follow-up (b = -1.32, P = 0.009, 95% CI -2.29, -0.34, d = 0.50), and for the number of days with pain, adolescents in the iCC-SCD group demonstrated fewer pain days compared with the Education group at 6-month follow-up (incident rate ratio = 0.63, P = 0.006, 95% CI 0.30, 0.95, d = 0.53). Treatment effects were also found for coping attempts, momentary mood, and fatigue. Several secondary outcomes did not change with intervention, including anxiety, depression, pain interference, and global impression of change. Future studies are needed to identify effective implementation strategies to bring evidence-based cognitive-behavioral therapy for sickle cell pain to SCD clinics and communities.
Despite significant efforts, the opioid crisis remains a pressing health concern affecting adolescents. The primary aim of this study was to describe recent sociodemographic shifts in the opioid ...epidemic. We examined whether rates of opioid use, including opioid misuse and opioid use disorder among 12 to 17 year olds in the United States, differ according to sociodemographic factors, physical and mental health, and substance use characteristics using data from the 2015 and 2016 National Survey on Drug Use and Health. We also examined motivations for opioid misuse. The study included 27,857 participants. Black, non-Hispanic adolescents were more likely to both use and misuse opioids as compared to white, non-Hispanic adolescents, a clear difference from previous studies. The main motivation for misuse by adolescents was relief of physical pain (50%, 95% confidence interval 46%-54%). Adolescents who reported pain relief as the major reason for misuse had increased odds of substance use as compared to adolescents who did not report any opioid misuse. However, odds for substance use was greatest among adolescents who reported reasons other than pain relief for opioid misuse. National Survey on Drug Use and Health self-report data suggest recent shifts in opioid misuse with minority adolescents appearing to be at increased risk of opioid misuse compared with white adolescents. Relief of physical pain is the most common motivation for opioid misuse.
Allostery is a ubiquitous biological mechanism in which a distant binding site is coupled to and drastically alters the function of a catalytic site in a protein. Allostery provides a high level of ...spatial and temporal control of the integrity and activity of biomolecular assembles composed of proteins, nucleic acids, or small molecules. Understanding the physical forces that drive allosteric coupling is critical to harnessing this process for use in bioengineering, de novo protein design, and drug discovery. Current microscopic models of allostery highlight the importance of energetics, structural rearrangements, and conformational fluctuations, and in this review, we discuss the synergistic use of solution NMR spectroscopy and computational methods to probe these phenomena in allosteric systems, particularly protein-nucleic acid complexes. This combination of experimental and theoretical techniques facilitates an unparalleled detection of subtle changes to structural and dynamic equilibria in biomolecules with atomic resolution, and we provide a detailed discussion of specialized NMR experiments as well as the complementary methods that provide valuable insight into allosteric pathways in silico. Lastly, we highlight two case studies to demonstrate the adaptability of this approach to enzymes of varying size and mechanistic complexity.
Understanding adolescent perspectives on prescribed opioids in the context of medical care for acute pain is needed to prevent opioid-related adverse outcomes. We explored factors that may influence ...opioid decision-making and use behaviors among adolescents prescribed opioids for acute pain.
We conducted semistructured interviews with 19 adolescents (63% females, ages 12 to 17) prescribed opioids upon discharge from surgery or intensive care unit admission. Interview transcripts were coded using inductive thematic analysis.
Five themes were identified: "Opioid use to reduce extreme pain and facilitate acute recovery"; "Familiarity with risks and negative effects of opioids"; "Assessment of opioid risk based on individual characteristics and use behaviors"; "Careful balance of risks, benefits, and symptoms when taking opioids"; "Importance of trusted adults for adolescent opioid management". Adolescents commonly believe opioids are only appropriate for severe pain that cannot be managed with other strategies. Most (but not all) adolescents were aware of addiction and other potential opioid harms and generally disapproved of misuse. However, a few adolescents would consider taking unprescribed opioids for severe pain. Adolescents wanted to be well informed for opioid decision-making, considering guidance from trusted adults.
Adolescents often demonstrated active and sound participation in shared opioid decision-making, influenced by complex integration of inputs and self-reflection. Conversely, potential factors that could contribute to risky behaviors included low personal risk perceptions, uncertainty about what constitutes opioid misuse, and avoidance of prescribed opioids despite extreme pain. Future studies may explore associations of adolescents' opioid decision-making with longer-term pain and opioid-related outcomes.
Acute and chronic pain are highly prevalent and impactful consequences of surgery across the lifespan, yet a comprehensive conceptual model encompassing biopsychosocial factors underlying acute to ...chronic pain transition is lacking, particularly in youth. Building on prior chronic postsurgical pain models, we propose a new conceptual model of biopsychosocial mechanisms of transition from acute to chronic postsurgical pain. This review aims to summarize existing research examining key factors underlying acute to chronic postsurgical pain transition in order to guide prevention and intervention efforts aimed at addressing this health issue in children. As pain transitions from acute nociceptive pain to chronic pain, changes in the peripheral and central nervous system contribute to the chronification of pain after surgery. These changes include alterations in sensory pain processing and psychosocial processes (psychological, behavioral, and social components), which promote the development of chronic pain. Patient-related premorbid factors (eg, demographic factors, genetic profile, and medical factors such as premorbid pain) may further modulate these changes. Factors related to acute injury and recovery (eg, surgical and treatment factors), as well as biological response to surgery (eg, epigenetic, inflammatory, and endocrine factors), may also influence this process. Overall, longitudinal studies examining temporal pathways of biopsychosocial processes including both risk and resiliency factors will be essential to identify the mechanisms involved in the transition from acute to chronic pain. Research is also needed to unravel connections between the acute pain experience, opioid exposure, and sensory pain processing during acute to chronic pain transition. Furthermore, future studies should include larger and more diverse samples to more fully explore risk factors in a broader range of pediatric surgeries. The use of conceptual models to guide intervention approaches targeting mechanisms of transition from acute to chronic pain will significantly advance this field and improve outcomes for children and adolescents undergoing surgery.
