RESUMO

BACKGROUND: In the USA, nirmatrelvir/ritonavir is authorized for the treatment of mild-to-moderate COVID-19 in patients at least 12 years of age, at high risk for progression to severe COVID-19. OBJECTIVES: To estimate the impact of outpatient nirmatrelvir/ritonavir on COVID-19 hospitalization risk in a US healthcare system. METHODS: We conducted a cohort study using electronic health records among outpatients with a positive SARS-CoV-2 PCR test between January and August 2022. We evaluated the association of nirmatrelvir/ritonavir therapy with time to hospitalization by estimating adjusted HRs and assessed the impact of nirmatrelvir/ritonavir on predicted COVID-19 hospitalizations using machine-learning methods. RESULTS: Among 44 671 patients, 4948 (11%) received nirmatrelvir/ritonavir, and 201 (0.4%) were hospitalized within 28 days of COVID-19 diagnosis. Nirmatrelvir/ritonavir recipients were more likely to be older, white, vaccinated, have comorbidities and reside in areas with higher average socioeconomic status. The 28 day cumulative incidence of hospitalization was 0.06% (95% CI: 0.02%-0.17%) among nirmatrelvir/ritonavir recipients and 0.52% (95% CI: 0.46%-0.60%) among non-recipients. For nirmatrelvir/ritonavir versus no therapy, the age-adjusted HR was 0.08 (95% CI: 0.03-0.26); the fully adjusted HR was 0.16 (95% CI: 0.05-0.50). In the machine-learning model, the primary features reducing predicted hospitalization risk were nirmatrelvir/ritonavir, younger age, vaccination, female gender and residence in a higher socioeconomic status area. CONCLUSIONS: COVID-19 hospitalization risk was reduced by 84% among nirmatrelvir/ritonavir recipients in a large, diverse healthcare system during the Omicron wave. These results suggest that nirmatrelvir/ritonavir remained highly effective in a setting substantially different than the original clinical trials.

RESUMO

BACKGROUND: Among ambulatory people with incomplete spinal cord injury (iSCI), balance deficits are a primary factor limiting participation in walking activities. There is broad recognition that effective interventions are needed to enhance walking balance following iSCI. Interventions that amplify self-generated movements (e.g., error augmentation) can accelerate motor learning by intensifying sensorimotor feedback and facilitating exploration of motor control strategies. These features may be beneficial for retraining walking balance after iSCI. We have developed a cable-driven robot that creates a movement amplification environment during treadmill walking. The robot applies a continuous, laterally-directed, force to the pelvis that is proportional in magnitude to real-time lateral velocity. Our purpose is to investigate the effects of locomotor training in this movement amplification environment on walking balance. We hypothesize that for ambulatory people with iSCI, locomotor training in a movement amplification environment will be more effective for improving walking balance and participation in walking activities than locomotor training in a natural environment (no applied external forces). METHODS: We are conducting a two-arm parallel-assignment intervention. We will enroll 36 ambulatory participants with chronic iSCI. Participants will be randomized into either a control or experimental group. Each group will receive 20 locomotor training sessions. Training will be performed in either a traditional treadmill environment (control) or in a movement amplification environment (experimental). We will assess changes using measures that span the International Classification of Functioning, Disability and Health (ICF) framework including 1) clinical outcome measures of gait, balance, and quality of life, 2) biomechanical assessments of walking balance, and 3) participation in walking activities quantified by number of steps taken per day. DISCUSSION: Training walking balance in people with iSCI by amplifying the individual's own movement during walking is a radical departure from current practice and may result in new strategies for addressing balance impairments. Knowledge gained from this study will expand our understanding of how people with iSCI improve walking balance and how an intervention targeting walking balance affects participation in walking activities. Successful outcomes could motivate development of clinically feasible tools to replicate the movement amplification environment within clinical settings. TRIAL REGISTRATION: NCT04340063.

RESUMO

Behavioral inhibition (BI) is a temperamental style characterized by cautious and fearful behaviors in novel situations. The present multi-method, longitudinal study examined whether young children's observed and parent-reported BI in social versus non-social contexts predicts different long-term psychosocial outcomes. Participants (N = 279) were drawn from a longitudinal study of socioemotional development. BI in social contexts ("social BI") was measured via children's observed wariness toward unfamiliar adults and peers at 24 and 36 months and parents' reports of children's social fear/shyness at 24, 36, and 48 months. BI in non-social contexts ("non-social BI") was measured via children's observed fearful responses to masks and novel toys, and parents' reports of children's distress to non-social novelty at 9 months and non-social fear at 48 months. At 15 years, anxiety was assessed via adolescent- and parent-reports, and global internalizing and externalizing problems were assessed via parent-reports. Confirmatory factor analysis showed that a two-factor model fit the BI data significantly better than a single-factor model, providing evidence for the dissociation of BI in social versus non-social contexts. Social BI was uniquely associated with adolescent social anxiety, whereas non-social BI was specifically associated with adolescent separation anxiety. Neither social BI nor non-social BI predicted global internalizing and externalizing problems, providing evidence for the specific relations between BI and anxiety problems. Together, these results suggest that young children's inhibited responses in social versus non-social situations predict different subtypes of anxiety problems in adolescence, highlighting the multifaceted nature of BI and the divergent trajectories of different anxiety problems.

RESUMO

Behavioral Inhibition is a temperament identified in the first years of life that enhances the risk for development of anxiety during late childhood and adolescence. Amongst children characterized with this temperament, only around 40 percent go on to develop anxiety disorders, meaning that more than half of these children do not. Over the past 20 years, research has documented within-child and socio-contextual factors that support differing developmental pathways. This review provides a historical perspective on the research documenting the origins of this temperament, its biological correlates, and the factors that enhance or mitigate risk for development of anxiety. We review as well, research findings from two longitudinal cohorts that have identified moderators of behavioral inhibition in understanding pathways to anxiety. Research on these moderators has led us to develop the Detection and Dual Control (DDC) framework to understand differing developmental trajectories among behaviorally inhibited children. In this review, we use this framework to explain why and how specific cognitive and socio-contextual factors influence differential pathways to anxiety versus resilience.

RESUMO

Previous work has shown that children's shyness is related to personal anxiety during social stress, but we know little about how shyness is related to anxiety during a peer's social stress. Children (Mage  = 10.22 years, SD = 0.81, N = 62) were paired with an unfamiliar peer and engaged in a speech task while electrocardiography was recorded. We modeled changes in children's heart rate, a physiological correlate of anxiety, while they observed their peer prepare and deliver a speech. Results revealed that the observing child's shyness related to increases in their heart rate during their peer's preparation period, but modulation of this arousal was sensitive to the presenting peer's anxious behavior while delivering their speech. Specifically, if the presenting child displayed high levels of anxious behavior, the observing child's shyness was related to further increases in heart rate, but if the presenting child displayed low levels of anxious behavior, the observing child's shyness was related to decreases in heart rate from the preparation period. Shy children may experience physiological arousal to a peer's social stress but can regulate this arousal based on social cues from the peer, which may be due to heightened social threat detection and/or empathic anxiety.

RESUMO

BACKGROUND: Multidrug-resistant Enterobacterales (MDR-E) are important pathogens. People living with human immunodeficiency virus (HIV; PLWH) may be at greater risk for MDR-E infection given relatively high antibiotic exposure and burden of comorbidities. METHODS: We analyzed data from 36 521 patients in a healthcare system in North Carolina who had a clinical culture with growth of an Enterobacterales species from 2000 to 2018; 440 were PLWH. We used generalized linear models to estimate prevalence ratios and differences, contrasting PLWH and people not living with HIV (PNLWH) for resistance to individual antibiotic classes, as well as MDR-E. We assessed trends in prevalence over time by calculating the 5-year moving average and fitting restricted cubic spline models. RESULTS: The overall prevalence of MDR-E was higher among PLWH (21.5%; 95% confidence interval [CI], 18.2%-25.1%) vs PNLWH (16.5%; 95% CI, 16.2%-16.9%), with an adjusted prevalence ratio of 1.38 (95% CI, 1.14-1.65). PLWH had higher rates of antimicrobial resistance than PNLWH for all antibiotic classes analyzed, including penicillins, penicillin/beta lactamase inhibitor combinations, and sulfonamides. MDR-E prevalence was 3 to 10 percentage points higher among PLWH than PNLWH throughout the study period based on the 5-year moving average. CONCLUSIONS: In a large clinical study population in the southeastern United States from 2000 to 2018, the prevalence of antibacterial resistance among Enterobacterales was consistently higher among PLWH than PNLWH. These data highlight the importance of identifying and mitigating the factors that contribute to antimicrobial resistance in PLWH, given the potential clinical consequences of these resistant pathogens.

RESUMO

BACKGROUND: Social anxiety is amongst the most prevalent adolescent mental health problems; however, it is often unrecognized due to its comorbidity with other anxiety problems such as generalized anxiety. Thus, understanding the unique developmental pathways to social anxiety is critical for improving its prevention. We examined the pathway from maternal shyness, when children were 4 years old, to adolescents' social anxiety at age 15 through social wariness at age 7. We hypothesized that childhood social wariness would mediate the association between maternal shyness and social anxiety in adolescence. METHODS: Participants (N = 291; 54% female) were followed from early childhood to adolescence. Mothers reported on their own shyness when children were 4 years old. Social wariness toward unfamiliar peers was observed in the laboratory at ages 4 and 7. Adolescent social anxiety and generalized anxiety were assessed via self-report, parent-report, and clinical diagnoses at age 15. RESULTS: Maternal shyness was positively associated with adolescent social anxiety but not generalized anxiety at age 15. Higher levels of maternal shyness at age 4 predicted greater social wariness at age 7, which in turn predicted greater social anxiety but not generalized anxiety at age 15. Social wariness at age 7 partially mediated the association between maternal shyness and adolescent social anxiety. CONCLUSIONS: This study identifies a unique developmental pathway from maternal shyness to adolescent social anxiety. Findings suggest that childhood social wariness connects maternal shyness to adolescent social anxiety.

RESUMO

INTRODUCTION: Research suggests that certain parenting behaviors are best suited to promote optimal child development, depending on a child's distinctive temperamental presentation. This multimethod, longitudinal study examines the interactive effect of parenting and temperament in early childhood on the developmental trajectory of social anxiety in adolescence. METHODS: Longitudinal growth modeling was used to examine the developmental trajectory of child social anxiety from age 9-15 and the interactive effect of parenting and child temperament at 36 months on the developmental trajectory of child social anxiety from age 9-15. RESULTS: The slope of social anxiety from age 9-15 suggested a decrease in social anxiety throughout early adolescence. Furthermore, 36-month behavioral inhibition (BI) predicted the trajectory of child social anxiety from age 9-15 when parents displayed low and high levels of dismissive and supportive parenting (at 36 months). CONCLUSIONS: Results support an interactive effect of infant temperament and parenting in early childhood (at 36 months) on the developmental trajectory of child social anxiety from age 9-15. Specifically, results suggest that engaging highly inhibited children with high supportive and low dismissive parenting may help reduce social anxiety over time in adolescence. Furthermore, parenting needs may differ for children high or low in BI to impact the developmental trajectory of social anxiety in adolescence, such that children who are high BI seem to benefit from low dismissive and high supportive parenting, and children who are low in BI seem to benefit more from high dismissive parenting.

RESUMO

BACKGROUND: Routine surveillance protocols rely heavily on endomyocardial biopsy (EMB) for detection of rejection in pediatric heart transplant recipients. More sensitive echocardiographic tools to assess rejection may help limit the number of EMBs. This study compared changes in left ventricular (LV) strain in patients who had rejection versus those who did not. METHODS: A single center retrospective review was conducted between 2013 and 2020. Patients were categorized based on rejection history. Echocardiograms were evaluated at the time of 2 consecutive EMBs; in the rejection group, the second echocardiogram was collected at the time of a rejection episode. Conventional measures of LV function and speckle-tracking echocardiography-derived longitudinal (LS) and circumferential strain (CS) were measured. RESULTS: 17 patients were in the non-rejection group and 17 were in the rejection group (30 total rejection episodes). The rejection group was older at the time of transplant (12.5 vs. 1.3 years, p = .01). A decline in CS was seen in the rejection group at the second echocardiogram [-18.5 (IQR -21.5, -14.6) to -15.7 (IQR -19.8, -13.2)] while CS improved in the non-rejection group [-20.8 (IQR -23.9, -17.8) to -23.9 (IQR -24.9, -20.1)]. This difference in change reached significance (p = .02). A similar pattern was seen in LS that neared significance (p = .06). There was no significant difference in ejection fraction change (p = .24). CONCLUSIONS: Patients in the non-rejection group displayed improvement in CS between echocardiograms while patients in the rejection group showed subsequent decline. Worsening of LV CS may help identify acute rejection in the early post-transplant period.

RESUMO

BACKGROUND: Although mortality has decreased considerably in pediatric heart transplantation, waitlist and post-transplant death rates remain notable. End-of-life focused research in this population, however, is very limited. This Pediatric Heart Transplant Society study aimed to describe the circumstances surrounding death of pediatric heart transplant patients. METHODS: A retrospective analysis of the multi-institutional, international, Pediatric Heart Transplant Society registry was conducted. Descriptive statistics and univariate analyses were performed to 1) describe end-of-life in pediatric pre- and post-heart transplant patients and 2) examine associations between location of death and technological interventions at end-of-life with demographic and disease factors. RESULTS: Of 9217 patients (0-18 years) enrolled in the registry between 1993 and 2018, 2804 (30%) deaths occurred; 1310 while awaiting heart transplant and 1494 post-heart transplant. The majority of waitlist deaths (89%) occurred in the hospital, primarily in ICU (74%) with most receiving mechanical ventilation (77%). Fewer post-transplant deaths occurred in the hospital (22%). Out-of-hospital death was associated with older patient age (p < .01). CONCLUSIONS: ICU deaths with high use of technological interventions at end-of-life were common, particularly in patients awaiting heart transplant. In this high mortality population, findings raise challenging considerations for clinicians, families, and policy makers on how to balance quality of life amidst high risk for hospital-based death.

RESUMO

This manuscript outlines a clinical approach to vasoplegia incorporating the current state of knowledge regarding vasoplegia in pediatric patients immediately post-transplant and to identify modifiable factors both pre- and post-transplant that may reduce post-operative morbidity, end-organ dysfunction, and mortality. Centers participating in the Pediatric Heart Transplant Society (PHTS) were asked to provide their internal protocols and rationale for vasoplegia management, and applicable adult and pediatric data were reviewed. The authors synthesized the above protocols and literature into the following description of clinical approaches to vasoplegia highlighting areas of both broad consensus and of significant practice variation.

RESUMO

OBJECTIVE: This document is designed to outline the definition, pathogenesis, diagnostic modalities and therapeutic measures to treat antibody-mediated rejection in children postheart transplant METHODS: Literature review was conducted by a Pediatric Heart Transplant Society (PHTS) working group to identify existing pediatric and adult studies on antibody-mediated rejection (AMR). In addition, the centers participating in PHTS were asked to submit their approach to diagnosis and management of pediatric AMR. This document synthesizes information gathered from both these sources to highlight a practical approach to diagnosing and managing a child with AMR postheart transplant. This document may not represent the practice at all centers in the PHTS and serves as a starting point to understand an approach to this clinical scenario.

RESUMO

The authors examined temperamental and sociocognitive predictors of socially anxious behavior from preschool to early adolescence. Children (N = 227; 59% male; 69% White) completed a speech task at ages 5, 7, 10, and 13 and socially anxious behaviors were coded. Behavioral inhibition (BI) was assessed at ages 2/3 and Theory of Mind (ToM) was assessed at age 4. Data collection occurred between 2003 and 2016. Three trajectories of socially anxious behavior were identified: high stable, average increasing, and low stable. Higher BI was related to the high stable trajectory, whereas lower ToM was related to the increasing trajectory of socially anxious behavior. There are heterogenous pathways of socially anxious behavior, which may be uniquely influenced by early temperamental and sociocognitive factors.

RESUMO

Recent models of psychopathology suggest the presence of a general factor capturing the shared variance among all symptoms along with specific psychopathology factors (e.g., internalizing and externalizing). However, few studies have examined predictors that may serve as transdiagnostic risk factors for general psychopathology from early development. In the current study we examine, for the first time, whether observed and parent-reported infant temperament dimensions prospectively predict general psychopathology as well as specific psychopathology dimensions (e.g., internalizing and externalizing) across childhood. In a longitudinal cohort (N = 291), temperament dimensions were assessed at 4 months of age. Psychopathology symptoms were assessed at 7, 9, and 12 years of age. A bifactor model was used to estimate general, internalizing, and externalizing psychopathology factors. Across behavioral observations and parent-reports, higher motor activity in infancy significantly predicted greater general psychopathology in mid to late childhood. Moreover, low positive affect was predictive of the internalizing-specific factor. Other temperament dimensions were not related with any of the psychopathology factors after accounting for the general psychopathology factor. The results of this study suggest that infant motor activity may act as an early indicator of transdiagnostic risk. Our findings inform the etiology of general psychopathology and have implications for the early identification for children at risk for psychopathology.

RESUMO

Mind wandering is a ubiquitous experience during adulthood and has received significant scholarly attention in recent years. Relatively few studies, however, have examined the phenomenon in children. Building on recent work, the current study examined the frequency and validity of children's reports of mind wandering while completing a minimalistic task previously unused in past child research-the Metronome Response Task (MRT) [Journal of Experimental Psychology: Human Perception and Performance (2013), Vol. 39, pp. 1-5]. Furthermore, the current study examined how parent reports of executive dysfunction in daily life relate to children's reports of mind wandering and behavioral performance in the MRT. A total of 81 children aged 7-9 years completed the MRT, the demands of which simply involved pressing a key on a computer keyboard in concert with the unwavering tones of a metronome. Sporadic experience-sampling probes gauged whether children were on-task or mind wandering. Parents also reported on their children's day-to-day difficulties with executive functioning across several domains. A series of multilevel models revealed that children reported being on-task more frequently then mind wandering and that children were more variable and less synchronous in their keypresses preceding reports of mind wandering than preceding reports of being on task. In addition, parent-reported difficulties with behavioral regulation predicted higher rates of mind wandering, whereas both behavioral dysregulation and metacognitive difficulties predicted lower MRT performance. These findings suggest that children are able to reliably report on their experiences of mind wandering in boredom-inducing contexts and advance our understanding of the factors underlying children's experience of mind wandering under real-world conditions.

RESUMO

OBJECTIVES: To explore misconceptions regarding addiction potential of prescription opioids among cancer survivors. METHODS: A qualitative study using semi-structured interviews were conducted with a purposive sample of cancer survivors (N = 25) treated with prescription opioids for pain management. Interviews were audio recorded, transcribed and coded using Atlas.ti version 8. Inductive applied thematic analysis techniques were employed to identify emergent themes. RESULTS: The majority of participants were breast cancer survivors (88%) who underwent a combination of surgery, chemotherapy and radiation (72%). Thematic analysis revealed that (1) cancer survivors view opioids as an illicit drug, (2) media narrative of the opioid epidemic increased negative perception of opioid use for cancer-related pain, (3) perceptions of opioids were also informed by experiences of friends and family with an opioid use disorder, (4) poor understanding of terminology resulted in misconceptions of opioid use and addiction and (5) fear of opioid addiction resulted in unrelieved cancer pain and poor quality of life. CONCLUSION: Our findings support previously identified concerns among cancer patients about fear of addiction to opioids, a barrier to effective pain management. It highlights the importance for health care providers caring for cancer survivors to continue to address misconceptions about prescribed opioids.

RESUMO

BACKGROUND: Hypertrophic cardiomyopathy is the leading cause of sudden cardiac death (SCD) in children and young adults. Our objective was to develop and validate a SCD risk prediction model in pediatric hypertrophic cardiomyopathy to guide SCD prevention strategies. METHODS: In an international multicenter observational cohort study, phenotype-positive patients with isolated hypertrophic cardiomyopathy <18 years of age at diagnosis were eligible. The primary outcome variable was the time from diagnosis to a composite of SCD events at 5-year follow-up: SCD, resuscitated sudden cardiac arrest, and aborted SCD, that is, appropriate shock following primary prevention implantable cardioverter defibrillators. Competing risk models with cause-specific hazard regression were used to identify and quantify clinical and genetic factors associated with SCD. The cause-specific regression model was implemented using boosting, and tuned with 10 repeated 4-fold cross-validations. The final model was fitted using all data with the tuned hyperparameter value that maximizes the c-statistic, and its performance was characterized by using the c-statistic for competing risk models. The final model was validated in an independent external cohort (SHaRe [Sarcomeric Human Cardiomyopathy Registry], n=285). RESULTS: Overall, 572 patients met eligibility criteria with 2855 patient-years of follow-up. The 5-year cumulative proportion of SCD events was 9.1% (14 SCD, 25 resuscitated sudden cardiac arrests, and 14 aborted SCD). Risk predictors included age at diagnosis, documented nonsustained ventricular tachycardia, unexplained syncope, septal diameter z-score, left ventricular posterior wall diameter z score, left atrial diameter z score, peak left ventricular outflow tract gradient, and presence of a pathogenic variant. Unlike in adults, left ventricular outflow tract gradient had an inverse association, and family history of SCD had no association with SCD. Clinical and clinical/genetic models were developed to predict 5-year freedom from SCD. Both models adequately discriminated between patients with and without SCD events with a c-statistic of 0.75 and 0.76, respectively, and demonstrated good agreement between predicted and observed events in the primary and validation cohorts (validation c-statistic 0.71 and 0.72, respectively). CONCLUSION: Our study provides a validated SCD risk prediction model with >70% prediction accuracy and incorporates risk factors that are unique to pediatric hypertrophic cardiomyopathy. An individualized risk prediction model has the potential to improve the application of clinical practice guidelines and shared decision making for implantable cardioverter defibrillator insertion.

RESUMO

Individuals with a behaviorally inhibited (BI) temperament are more likely to develop social anxiety. However, the mechanisms by which socially anxious behavior emerges from BI are unclear. Variation in different forms of top-down control, specifically executive functions (EF), may play distinct roles and characterize differential pathways to social anxiety. Here 291 children were assessed for BI in toddlerhood (ages 2 and 3), parent-reported inhibitory control and set shifting during middle childhood (age 7), and multidimensional assessment of socially anxious behavior completed during late childhood and early adolescence (ages 9 and 12). Structural equation modeling revealed that early variation in BI predicted the development of socially anxious behavior through either higher levels of parent-reported inhibitory control or lower levels of parent-reported set shifting. These data reinforce the notion that top-down control does not uniformly influence relations between temperament and socially anxious behavior. These data suggest novel approaches to thinking about the role of EFs and social anxiety outcomes as children approach adolescence.

RESUMO

Cancer survivors' perceptions of prescription opioid medication (POM) and the health communications they receive about POM's safety and effectiveness are embedded within the national discourse of the opioid epidemic. Using qualitative methods, this community-based study explored the health communication and the educational needs of diverse cancer survivors who received opioid agonist treatment to manage cancer pain. Our community-based sample consisted of 25 cancer survivors, 24 healthcare providers, and six community-level stakeholders. Over half of the cancer survivors interviewed were from underrepresented minority groups (52% African American and 12% Hispanic/Latino). The data were analyzed using applied thematic analysis techniques. The over-arching themes include the need to (1) provide clear, consistent, and comprehensive education and information about POM to ensure safe use; (2) discuss the risks, benefits, and proper use of POM in the treatment of cancer-related pain; (3) communicate realistic expectations and address common misconceptions about pain; and (4) address cancer survivor beliefs and concerns surrounding fear of addiction. Our findings highlight the need for effective cancer education and communication about opioid agonist treatment and POM in plain simple language that is easy to understand, relevant, and culturally appropriate. Recommendations for cancer education and suggestions for future research are discussed.

RESUMO

Extensive research has demonstrated the transactional nature of parent-child psychopathology, with limited studies examining these effects during late adolescence and none, to our knowledge, longitudinally during the COVID-19 pandemic. The current study examined the cross-lagged effects of parent and adolescent internalizing symptoms during the COVID-19 pandemic and the moderating role of avoidant coping. A sample of 291 adolescents (Age mean = 18.27; 53% female; 61% White) and their parents rated their own anxiety and depressive symptoms and coping during the first two months following stay-at-home orders during the COVID-19 pandemic. Parent internalizing symptoms at the first assessment predicted adolescent internalizing symptoms at the second assessment. Adolescent avoidant coping style moderated this effect of parent internalizing symptoms on adolescent internalizing symptoms in the subsequent month, such that parent internalizing symptoms predicted child internalizing symptoms only among adolescents with moderate to high rates of avoidant coping. Follow-up analyses indicated different patterns when examining depressive and anxiety symptoms separately. The results highlight complex family dynamics between adolescents and their parents and begin to differentiate how individual characteristics impact the response to a significant life event such as the COVID-19 pandemic.
