An individual is typically considered an adult at age 18, although the age of adulthood varies for different legal and social policies. A key question is how cognitive capacities relevant to these policies change with development. The current study used an emotional go/no-go paradigm and functional neuroimaging to assess cognitive control under sustained states of negative and positive arousal in a community sample of one hundred ten 13- to 25-year-olds from New York City and Los Angeles. The results showed diminished cognitive performance under brief and prolonged negative emotional arousal in 18- to 21-year-olds relative to adults over 21. This reduction in performance was paralleled by decreased activity in fronto-parietal circuitry, implicated in cognitive control, and increased sustained activity in the ventromedial prefrontal cortex, involved in emotional processes. The findings suggest a developmental shift in cognitive capacity in emotional situations that coincides with dynamic changes in prefrontal circuitry. These findings may inform age-related social policies.

Objectives: For children, adolescents, and young adults with complex chronic conditions advance care planning may be a vital component of optimal care. Advance care planning outcomes research has previously focused on seriously ill adults and adolescents with cancer where it is correlated with high-quality end-of-life care. The impact of advance care planning on end-of-life outcomes for children, adolescents, and young adults with complex chronic conditions is unknown, thus we sought to evaluate parental preferences for advance care planning and to determine whether advance care planning and assessment of specific family considerations during advance care planning were associated with differences in parent-reported end-of-life outcomes. Design: Cross-sectional survey. Setting: Large, tertiary care children’s hospital. Subjects: Bereaved parents of children, adolescents, and young adults with complex chronic conditions who died between 2006 and 2015. Interventions: None. Measurement and Main Results: One-hundred fourteen parents were enrolled (54% response rate) and all parents reported that advance care planning was important, with a majority (70%) endorsing that discussions should occur early in the illness course. Parents who reported advance care planning (65%) were more likely to be prepared for their child’s last days of life (adjusted odds ratio, 3.78; 95% CI, 1.33–10.77), to have the ability to plan their child’s location of death (adjusted odds ratio, 2.93; 95% CI, 1.06–8.07), and to rate their child’s quality of life during end-of-life as good to excellent (adjusted odds ratio, 3.59; 95% CI, 1.23–10.37). Notably, advance care planning which included specific assessment of family goals was associated with a decrease in reported child suffering at end-of-life (adjusted odds ratio, 0.23; 95% CI, 0.06–0.86) and parental decisional regret (adjusted odds ratio, 0.42; 95% CI, 0.02–0.87). Conclusions: Parents of children, adolescents, and young adults with complex chronic conditions highly value advance care planning, early in the illness course. Importantly, advance care planning is associated with improved parent-reported end-of-life outcomes for this population including superior quality of life. Further studies should evaluate strategies to ensure high-quality advance care planning including specific assessment of family goals.

Head motion causes artifacts in functional magnetic resonance imaging (fMRI) scans, a problem especially relevant for task-free resting state paradigms and for developmental, aging, and clinical populations. In a cohort spanning 7-28 years old (mean age 15) we produced customized head-anatomy-specific Styrofoam molds for each subject that inserted into an MRI head coil. We scanned these subjects under two conditions: using our standard procedure of packing the head coil with foam padding about the head to reduce head motion, and using the customized molds to reduce head motion. Here we report the effects found in our first 13 subjects. In 12 of 13 subjects, the molds reduced head motion throughout the scan, and reduced the fraction of a scan with substantial motion (i.e., volumes with motion notably above baseline levels of motion). Motion was reduced in all 6 head position estimates, especially in rotational, left-right, and superior-inferior directions. Motion was reduced throughout the full age range studied, including children, adolescents, and young adults. In terms of the fMRI data itself, quality indices improved with the head mold on, scrubbing analyses detected less distance-dependent artifact in scans with the head mold on, and distant-dependent artifact was less evident in the scans with the molds on, both for the entire scan and also during only low-motion volumes. Subjects found the molds comfortable. Head molds are thus effective tools for reducing head motion, and motion artifacts, during fMRI scans.

Apoptosis is a prominent metazoan cell death form. Yet, mutations in apoptosis regulators cause only minor defects in vertebrate development, suggesting that another developmental cell death mechanism exists. While some non-apoptotic programs have been molecularly characterized, none appear to control developmental cell culling. Linker-cell-type death (LCD) is a morphologically conserved non-apoptotic cell death process operating in Caenorhabditis elegans and vertebrate development, and is therefore a compelling candidate process complementing apoptosis. However, the details of LCD execution are not known. Here we delineate a molecular-genetic pathway governing LCD in C. elegans. Redundant activities of antagonistic Wnt signals, a temporal control pathway, and mitogen-activated protein kinase kinase signaling control heat shock factor 1 (HSF-1), a conserved stress-activated transcription factor. Rather than protecting cells, HSF-1 promotes their demise by activating components of the ubiquitin proteasome system, including the E2 ligase LET-70/UBE2D2 functioning with E3 components CUL-3, RBX-1, BTBD-2, and SIAH-1. Our studies uncover design similarities between LCD and developmental apoptosis, and provide testable predictions for analyzing LCD in vertebrates.DOI: http://dx.doi.org/10.7554/eLife.12821.001

BackgroundInvestments in faculty exchanges to build physician workforce capacity are increasing. Little attention has been paid to the expectations of host institution faculty and trainees. This prospective qualitative research study explored faculty and resident perspectives about guest faculty in paediatric departments in East Africa, asking (1) What are the benefits and challenges of hosting guest faculty, (2) What factors influence the effectiveness of faculty visits and (3) How do host institutions prepare for faculty visits?MethodsWe recruited 36 faculty members and residents from among four paediatric departments in East Africa to participate in semistructured interviews which were audio recorded and transcribed. Data were qualitatively analysed using principles of open coding and thematic analysis. We achieved saturation of themes.ResultsBenefits of faculty visits varied based on the size and needs of host institutions. Emergent themes included the importance of guest faculty time commitment, and mutual preparation to ensure that visit goals and scheduling met host needs. We documented conflicts that developed around guest emotional responses and ethical approaches to clinical resource limitations, which some hosts tried to prepare for and mitigate. Imbalance in resources led to power differentials; some hosts sought partnerships to re-establish control over the process of having guests.ConclusionsWe identified that guest faculty can assist paediatric institutions in building capacity; however, effective visits require: (1) mutually agreed on goals with appropriate scheduling, visit length and commitment to ensure that the visits meet the host's needs, (2) careful selection and preparation of guest faculty to meet the host's goals, (3) emotional preparation by prospective guests along with host orientation to clinical work in the host's setting and (4) attention to funding sources for the visit and mitigation of resulting power differentials.
