RESUMEN
OBJECTIVE: To assess feasibility of routine delirium screening using the Cornell Assessment of Pediatric Delirium (CAPD) in children admitted for rehabilitation with acquired brain injury (ABI), report on the prevalence of positive delirium screens in this population, and explore longitudinal trends in CAPD scores and their association with rehabilitation outcomes. DESIGN: Retrospective study. SETTING: Pediatric inpatient rehabilitation unit. PARTICIPANTS: 144 children (median 10.8 years) with ABI (N=144). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Percent compliance with twice daily delirium screening; prevalence of positive delirium screens; trajectories in CAPD scores and their relation with FIM for Children (WeeFIM) scores. RESULTS: Screening was feasible (mean 75% compliance for each of 144 children). Of 16,136 delirium screens, 29% were positive. 62% of children had ≥1 positive screen. Four primary patterns of CAPD trajectories were identified: Static Encephalopathy (10%), Episodic Delirium (10%), Improving (32%), and No Delirium (48%). Validity of these trajectories was demonstrated through association with WeeFIM and CALS outcomes. Younger age at admission was associated with positive delirium screens, and rehabilitation length of stay was significantly longer for the Improving group. CONCLUSIONS: Delirium occurs frequently in children with ABI during inpatient rehabilitation. Routine delirium screening provides clinically relevant information including the potential to facilitate early detection and intervention for medical complications. Longitudinal ratings of delirium symptoms may also have a role in developing a standardized definition for Post Traumatic Confusional State (PTCS) stage of recovery in children.

INTRODUCTION: Lung cancer screening using low-dose (LD) CT reduces lung cancer-specific and all-cause mortality in high-risk individuals, although significant barriers to screening remain. We assessed the outreach of a mobile lung cancer screening program to increase screening accessibility and early detection of lung cancer. METHODS: We placed a mobile CT unit in a high-traffic area in New York City and offered free screening to all eligible patients. Characteristics of the mobile screening cohort were compared with those of our hospital-based screening cohort. RESULTS: Between December 9, 2019, and January 30, 2020, a total of 216 patients underwent mobile LDCT screening. Compared with the hospital-based screening cohort, mobile screening participants were significantly more likely to be younger, be uninsured, and have lower smoking intensity and were less likely to meet 2013 US Preventive Services Task Force guidelines (but would meet their 2021 guidelines) and self-identify as White race and Hispanic ethnicity. Asian New Yorkers were substantially underrepresented in both hospital and mobile screening cohorts, compared with their level of representation in New York City. Two patients were diagnosed with lung cancer and were treated. Potentially clinically significant non-lung cancer findings were identified in 28.2%, most commonly moderate-severe coronary artery calcification and emphysema. CONCLUSIONS: Mobile LDCT screening is useful and effective in detecting lung cancer and other significant findings and may engage a distinct high-risk patient demographic. Disproportionately low screening rates among certain high-risk populations highlight the imperative of implementing strategies aimed at understanding health behaviors and access barriers for diverse populations. Effective care-navigation services, facilitating high-quality care for all patients, are critical.
RESUMEN
The neocortex (or pallium) consists of diverse cell types that are organized in a highly species-specific manner under strict spatiotemporal control during development. Many of the cell types are present transiently throughout development but contribute to permanent species-specific cortical features that are acquired through evolution. Therefore, capturing cell type-specific biological information has always been an important quest in the field of neurodevelopment. The progress in achieving fine cellular resolution has been slow due to technical challenges. However, with recent advancements in single-cell and multi-omics technologies, many laboratories have begun to successfully interrogate cellular and molecular mechanisms driving corticogenesis at single-cell resolution. In this review, we provide summarized results from many primary publications and several in-depth review articles that utilize or address single-cell genomics techniques to understand important topics, such as cellular and molecular mechanisms governing cortical progenitor proliferation, cell lineage progression, neuronal specification, and arealization, across multiple gyrencephalic (i.e., human and non-human primates) and lissencephalic species (i.e., mouse, reptiles, and songbirds). We also examine findings from recent studies involving epigenomic and posttranscriptional regulation of corticogenesis. In the discussion section, we provide our insights on the challenges the field currently faces as well as promising future applications of single cell technologies.

Patient-specific blood flow simulations may provide insight into disease progression, treatment options, and medical device design that would be difficult or impossible to obtain experimentally. However, publicly available image data and computer models for researchers and device designers are extremely limited. The National Heart, Lung, and Blood Institute sponsored Open Source Medical Software Corporation (contract nos. HHSN268200800008C and HHSN268201100035C) and its university collaborators to build a repository (www.vascularmodel.org) including realistic, image-based anatomic models and related hemodynamic simulation results to address this unmet need.
