Duchenne and Becker muscular dystrophy are allelic X-linked disorders causing progressive muscle weakness in males. Duchenne muscular dystrophy is caused by absence of dystrophin in muscle and brain; boys with Duchenne muscular dystrophy have a static cognitive impairment with mean Full Scale IQ approximately 1 standard deviation below the mean. Less is known of the cognitive profile of males with Becker muscular dystrophy, which is associated with variable alterations in the amount or size of the dystrophin protein. The aim of this study was to describe the cognitive and psychological profile of males with Becker muscular dystrophy. This was a prospective cohort study. Clinical data collected included age at diagnosis and assessment, socioeconomic status, serum creatine kinase level, and site of gene deletion/mutation (by exon number). The following psychological tests were used to assess general intellectual functioning, academic achievement, incidence and nature of behavioral problems: The Wechsler Intelligence Scales, The Wide Range Achievement Test-Revised, The Developmental Test of Visual-Motor Integration, The Child Behavior Checklist, and The Conner's Parent Rating Scale. Twenty-four males were enrolled. The Wechsler Full Scale IQ was normally distributed with a mean of 95.6 (SD 23.3), which did not differ significantly from the population mean. The frequency of learning difficulties for reading was 21%, for spelling was 32%, and for arithmetic was 26%, significantly higher than the frequency in the general population. The frequency of total behavioral problems in the clinical range was 67%, and the frequency of autism was 8.3%. Patients with Becker muscular dystrophy demonstrate a less homogeneous cognitive phenotype than that seen in Duchenne muscular dystrophy. Males with Becker muscular dystrophy have a high incidence of learning difficulties. Autism and behavioral and attention problems are also more common in Becker muscular dystrophy than in the general population.

Perceived racial bias and health-related stigma may be important to consider for future research investigating the psychological and physiological features of SCD for youth.

We investigated the potential impact of abuse history on autonomic regulation and psychological wellbeing in a sample of women who reported a history of abuse without Post Traumatic Stress Disorder. To measure autonomic regulation, heart rate data was collected before and after the participant rode a stationary bike for one mile. We found that abuse history was associated with less vagal regulation of the heart (i.e., respiratory sinus arrhythmia) and an inability to rapidly re-engage vagal regulation immediately following mild exercise to support a calm physiological state. These findings are consistent with clinical impressions that abused individuals may have a lower threshold to express fight/flight behaviors in response to stress and have difficulty shifting from mobilization to calmness. We also found that abuse history was related to psychological wellbeing. Women with an abuse history reported a greater use of dysfunctional coping methods and lower self-concept. Further, analyses indicated that there was a cumulative effect, whereby women who reported more recent abuse reported using more dysfunctional coping methods, having more mood disturbance, and lower self-concept. The findings underscore the importance of evaluating both the psychological and physiological effects of trauma, even in the absence of a diagnosis of PTSD.

Because healthcare providers may be experiencing moral injury (MI), we inquired about their healthcare morally distressing experiences (HMDEs), MI perpetrated by self (Self MI) or others (Others MI), and burnout during the COVID-19 pandemic. Participants were 265 healthcare providers in North Central Florida (81.9% female, Mage = 37.62) recruited via flyers and emailed brochures that completed online surveys monthly for four months. Logistic regression analyses investigated whether MI was associated with specific HMDEs, risk factors (demographic characteristics, prior mental/medical health adversity, COVID-19 protection concern, health worry, and work impact), protective factors (personal resilience and leadership support), and psychiatric symptomatology (depression, anxiety, and PTSD). Linear regression analyses explored how Self/Others MI, psychiatric symptomatology, and the risk/protective factors related to burnout. We found consistently high rates of MI and burnout, and that both Self and Others MI were associated with specific HMDEs, COVID-19 work impact, COVID-19 protection concern, and leadership support. Others MI was also related to prior adversity, nurse role, COVID-19 health worry, and COVID-19 diagnosis. Predictors of burnout included Self MI, depression symptoms, COVID-19 work impact, and leadership support. Hospital administrators/supervisors should recognize the importance of supporting the HCPs they supervise, particularly those at greatest risk of MI and burnout.
