Communication difficulties are among the most frequent characteristics of children with autism spectrum disorders (ASD). Lack of communication can have a significant impact on the child’s life. Augmentative and alternative communication (AAC) apps are a common form of AAC interventions that involve a combination of affordable technology with software that can be utilized to assist with communication. While AAC apps have been found to have some impact on improving the communication skills of children with ASD, current research exploring this topic is still limited. Focusing on the design process of AAC apps may provide better insight into improving clinical outcomes and user success. The user-centered design process incorporates a continuous cycle of user feedback to help inform and improve the functions and the capabilities of the technology, and it is an essential component in AAC app development. This article outlines how the user-centered design process could be adopted for the development of AAC apps for children with ASD.

Background In noncancer populations, insomnia is known to affect neurocognitive processes. Although the prevalence of insomnia appears to be elevated in survivors of childhood cancer, relatively little is known about its association with neurocognitive performance in this at-risk population. Methods A total of 911 survivors (51.9% female; mean [SD] age, 34 [9.0] years; time since diagnosis, 26 [9.1] years) completed direct assessments of attention, memory, processing speed, and executive functioning and self-reported symptoms of sleep (Pittsburgh Sleep Quality Index), fatigue (Functional Assessment of Chronic Illness Therapy-Fatigue), and daytime sleepiness (Epworth Sleepiness Scale). Sex-stratified general linear models were used to examine associations between insomnia and neurocognitive performance, with adjustment for treatment exposures and chronic health conditions. All statistical tests were two-sided. Results Insomnia was reported by 22.1% of females and 12.3% of males (P < .001). After adjustment for neurotoxic treatment exposures, insomnia (vs healthy sleepers with no daytime fatigue or sleepiness) was associated with worse neurocognitive performance in the domains of verbal reasoning, memory, attention, executive function, and processing speed (verbal reasoning: males β = −0.34, P = .04, females β = −0.57, P < .001; long-term memory: males β = −0.60, P < .001, females β = −0.36, P = .02; sustained attention: males β = −0.85, P < .001, females β = −0.42, P = .006; cognitive flexibility: males β = −0.70, P = .002, females β = −0.40, P = .02). Self-reported sleep disturbance without daytime fatigue or sleepiness or daytime fatigue or sleepiness alone were not consistently associated with poorer neurocognitive performance. Conclusions Insomnia was highly prevalent and contributed to the neurocognitive burden experienced by adult survivors of childhood cancer. Treatment of insomnia may improve neurocognitive problems in survivors.

BACKGROUND: Suicide is a serious public health concern. An increased risk of suicide ideation previously has been reported among survivors of childhood cancer. METHODS: Suicide mortality was assessed for all potentially eligible survivors (those aged ≥18 years who were ≥5 years after their cancer diagnosis; 7312 survivors). Risk factors for acute suicidal ideation were assessed among clinically evaluated survivors (3096 survivors) and the prevalence of acute ideation was compared with that of community controls (429 individuals). The prevalence of 12-month suicidality was assessed among survivors who could be compared with population data (1255 survivors). Standardized mortality ratios compared rates of suicide mortality among survivors with those of the general population. Risk ratios (RRs) and 95% confidence intervals (95% CIs) derived from generalized linear models identified risk factors associated with acute suicidal ideation. Standardized incidence ratios (SIRs) compared the prevalence of 12-month suicidality among survivors with that of a matched sample from the general population. RESULTS: Survivors reported a similar 12-month prevalence of ideation compared with the general population (SIR, 0.68; 95% CI, 0.35-1.01

Background: Childhood cancer survivors are at risk for cardiovascular morbidity and mortality that is not fully explained by cancer-directed therapies. We examined the contribution of emotional stress and distress to cardiac health in adult survivors of childhood cancer. Methods: Participants included 3,267 adult survivors enrolled in the St. Jude Lifetime Cohort Study [median (range) 29.9 (18.1–64.5) years of age; 7.7 (0–24.8) years at diagnosis; 48.4% female]. Survivors completed comprehensive medical assessments and standardized measures of depression, anxiety, posttraumatic stress symptoms (PTSS), and perceived stress. Cardiovascular-related conditions included hypertension, diabetes, dyslipidemia, cardiomyopathy, dysrhythmia, myocardial infarction (severity graded 0–4), and metabolic syndrome (yes/no). Multivariable modified Poisson models examined associations between symptoms of stress/distress and cardiovascular outcomes. Longitudinal associations between stress/distress and new-onset cardiovascular outcomes, defined as a change from grade ≤1 at initial evaluation to grade ≥2 at follow-up (median 3.9 years) were examined in 1,748 participants. Results: In multivariable cross-sectional models, stress/distress was associated with hypertension [risk ratio (RR) = 1.24; 95% confidence interval (CI), 1.07–1.43], dyslipidemia (RR = 1.29; 95% CI, 1.03–1.61), and metabolic syndrome (RR = 1.35; 95% CI, 1.17–1.54) independent of known cardiovascular risk factors. In longitudinal models, stress/distress was associated with new-onset dysrhythmia (RR = 2.87; 95% CI, 1.21–6.78), perceived stress with hypertension (RR = 1.42; 95% CI, 1.04–1.95), and PTSS and anxiety with dyslipidemia (RR = 1.72; 95% CI, 1.13–2.62; RR = 1.54; 95% CI, 1.01–2.35, respectively). Conclusions: Stress/distress is independently associated with adverse cardiovascular outcomes among childhood cancer survivors. Impact: Improving psychological health may serve as a potential intervention target for optimizing cardiac health among childhood cancer survivors.
