Electrocardiographic QTc as a Surrogate Measure of Cardiac Risk in Children, Adolescents, and Young Adults With Eating Disorders

The study goal was to investigate electrocardiographic findings, including corrected QT interval (QTc), in patients aged 8 to 23 with eating disorders (EDs) at presentation, compared with an age-and sex-matched control population. We retrospectively reviewed 200 ED patients, and 200 controls. Blinded electrocardiograms (ECGs) were interpreted by an expert reader, and QT intervals corrected using the Bazett formula. Eating disorder patients were 89.5% female, with mean age 16.4 years and median percent median body mass index (BMI)-for-age (%mBMI)a of 91.1%. In ED patients, QTc was significantly shorter than controls (399.6 vs 415.0msec, P < .001). After adjusting for height, %mBMI, sex, magnesium level, and bradycardia, mean QTc duration in patients with anorexia nervosa-restricting subtype (AN-R) was significantly shorter than other ED patients (P = .010). Higher %mBMI was associated with shorter QTc duration (P = .041) after adjusting for height, magnesium, bradycardia, and Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) diagnosis. Within the ED group, no significant association was identified between QTc and medications, electrolytes, or inpatient status.

A Structured Peer Assessment Method with Regular Reinforcement Promotes Longitudinal Self-Perceived Development of Medical Students' Feedback Skills

BACKGROUND

Given that training is integral to providing constructive peer feedback, we examined the impact of a regularly reinforced, structured peer assessment method on student-reported feedback abilities throughout a two-year preclinical Communication Skills course.

METHODS

Three consecutive 32-student medical school classes were introduced to the Observation-Reaction-Feedback method for providing verbal assessment during Year 1 Communication Skills orientation. In biweekly small-group sessions, students received worksheets reiterating the method and practiced giving verbal feedback to peers. Periodic questionnaires evaluated student perceptions of feedback delivery and the Observation-Reaction-Feedback method.

RESULTS

Biweekly reinforcement of the Observation-Reaction-Feedback method encouraged its uptake, which correlated with reports of more constructive, specific feedback. Compared to non-users, students who used the method noted greater improvement in comfort with assessing peers in Year 1 and continued growth of feedback abilities in Year 2. Comfort with providing modifying feedback and verbal feedback increased over the two-year course, while comfort with providing reinforcing feedback and written feedback remained similarly high. Concurrently, student preference for feedback anonymity decreased.

CONCLUSIONS

Regular reinforcement of a peer assessment framework can increase student usage of the method, which promotes the expansion of self-reported peer feedback skills over time. These findings support investigation of analogous strategies in other medical education settings.

Promoting resiliency in adolescents during a pandemic: A guide for clinicians and parents

The COVID-19 pandemic has dramatically affected every aspect of daily life. Parents of adolescents, in particular, may be facing unique challenges in helping them navigate unexpected changes to their daily routine. This article discusses how adolescents may respond to stressful and traumatic situations and provides recommendations for clinicians who may be advising parents of adolescents or parenting their own children.

Reconciling technology and humanistic care: Lessons from the next generation of physicians

PURPOSE

There is concern among physicians that the rising use of technology in medicine may have a negative impact on compassionate patient-centered care. This study explores medical student attitudes and ideas about technology in medicine in order to consider ways to achieve symbiosis between technology use and the delivery of humanistic, patient-centered care.

METHODS

This qualitative study uses data from 138 essays written by medical students in the United States and Canada responding to the prompt "Using a real life experience, describe how technology played a role, either negatively or positively, in the delivery of humanistic patient care." Data were analyzed for themes about technology and the impact on humanistic patient care.

RESULTS

Seven themes emerged from the medical students' essays: Patient Perspective; Life-Giving versus Life-Prolonging; Boundaries between Human and Technology; Distancing versus Presence; Adapting to Change; Tools to Enhance Care; and Definitions of Technology.

CONCLUSION

Listening to medical students lends insight into ways to integrate technology into the healthcare environment, to ensure that physicians' ability to deliver compassionate care is enhanced, not hindered. Utilizing perceptions of the next generation of physicians, educational and developmental strategies are proposed to ensure the successful integration of technology with humanistic patient-centered care.

The Origins of Cognitive Deficits in Victimized Children: Implications for Neuroscientists and Clinicians

OBJECTIVE

Individuals reporting a history of childhood violence victimization have impaired brain function. However, the clinical significance, reproducibility, and causality of these findings are disputed. The authors used data from two large cohort studies to address these research questions directly.

METHOD

The authors tested the association between prospectively collected measures of childhood violence victimization and cognitive functions in childhood, adolescence, and adulthood among 2,232 members of the U.K. E-Risk Study and 1,037 members of the New Zealand Dunedin Study who were followed up from birth until ages 18 and 38 years, respectively. Multiple measures of victimization and cognition were used, and comparisons were made of cognitive scores for twins discordant for victimization.

RESULTS

Individuals exposed to childhood victimization had pervasive impairments in clinically relevant cognitive functions, including general intelligence, executive function, processing speed, memory, perceptual reasoning, and verbal comprehension in adolescence and adulthood. However, the observed cognitive deficits in victimized individuals were largely explained by cognitive deficits that predated childhood victimization and by confounding genetic and environmental risks.

CONCLUSIONS

Findings from two population-representative birth cohorts totaling more than 3,000 individuals and born 20 years and 20,000 km apart suggest that the association between childhood violence victimization and later cognition is largely noncausal, in contrast to conventional interpretations. These findings support the adoption of a more circumspect approach to causal inference in the neuroscience of stress. Clinically, cognitive deficits should be conceptualized as individual risk factors for victimization as well as potential complicating features during treatment.
