Article Synopsis
  • A 13-year-old neutered male Lagotto Romagnolo presented with diarrhea and decreased appetite, leading to imaging that revealed pneumatosis intestinalis.
  • Further tests diagnosed multicentric lymphoma, and chemotherapy was started.
  • After treatment, the lymphoma went into clinical remission, and the pneumatosis intestinalis resolved on follow-up scans, highlighting the need to investigate underlying causes of pneumatosis intestinalis, including cancer, after ruling out emergencies.

The current technologies to place new DNA into specific locations in plant genomes are low frequency and error-prone, and this inefficiency hampers genome-editing approaches to develop improved crops. Often considered to be genome 'parasites', transposable elements (TEs) evolved to insert their DNA seamlessly into genomes. Eukaryotic TEs select their site of insertion based on preferences for chromatin contexts, which differ for each TE type.

Humans continuously alternate between online attention to the current environment and offline attention to internally generated thought and imagery. This may be a fundamental feature of the waking brain, but remains poorly understood. Here, we took a data-driven approach to defining online and offline states of wakefulness, using machine learning methods applied to measures of sensory responsiveness, subjective report, electroencephalogram (EEG), and pupil diameter.

The COVID-19 pandemic has not only led to massive global mortality and morbidity, but it has also fueled an infodemic of false and misleading information about COVID-19 and vaccines. The spread of misinformation and disinformation on vaccine safety and efficacy has contributed to vaccine hesitancy and distrust of public health institutions and has undermined the public health response to the COVID-19 pandemic. Because communication plays a monumental role in pandemic preparedness, a promising approach to countering the COVID-19 infodemic is empowering peers to serve as trusted messengers to provide accurate information using evidence-based communication approaches.

Disparities in access to pediatric eye care among school-age children pose significant challenges to their health and well-being; addressing these disparities will necessitate coordination across multiple systems. Although vision screenings are mandated in most US states, differences persist in terms of who receives screenings and subsequent follow-up care. Racial, ethnic, and socioeconomic factors exacerbate the issue, with potential ramifications of unaddressed eye problems on learning performance and the risk of widening preexisting educational disparities.

Introduction: Schools were uniquely impacted during the COVID-19 (SARS-COV-2) pandemic. We sought to elucidate how parents/guardians of elementary and middle school students in Maryland navigated the return to in-person school following remote instruction. We also sought to understand how they perceived communication about school-based COVID-19 mitigation strategies and their preferences for the content and format of public health communication about COVID-19 mitigation in schools.

Web-based survey data collection has become increasingly popular, and limitations on in-person data collection during the COVID-19 pandemic have fueled this growth. However, the anonymity of the online environment increases the risk of fraudulent responses provided by bots or those who complete surveys to receive incentives, a major risk to data integrity. As part of a study of COVID-19 and the return to in-person school, we implemented a web-based survey of parents in Maryland between December 2021 and July 2022.

The academic, socioemotional, and health impacts of school policies throughout the COVID-19 pandemic have been a source of many questions that require accurate information about the extent of onsite schooling occurring. This article investigates school operational status datasets during the pandemic, comparing (1) self-report data collected nationally on the household level through a Facebook-based survey, (2) county-level school policy data, and (3) a school-level closure status dataset based on phone GPS tracking. The percentage of any onsite instruction within states and counties are compared across datasets from December 2020 to May 2021.

Article Synopsis
  • Traditional studies focused on the brain's "online" state during active engagement with the environment, but new evidence suggests significant time is spent in an "offline" state, where attention shifts inward.
  • This research aimed to understand the role of these alternating states in balancing the needs for encoding new information and consolidating existing memories.
  • Findings show that a distinct offline state, characterized by certain brain activity and reduced external attention, is linked to better memory performance, supporting the idea that even short periods of being "offline" can enhance memory consolidation.

Introduction: Although factors such as urbanicity, population demographics, and political affiliation have been linked with COVID-19 masking behavior and policy in community settings, little work has investigated factors associated with school mask policies. We sought to characterize United States state and school district student COVID-19 masking policies during the 2021-22 school year and determine predictors of these mandates at four time points, including before and after federal guidance relaxed school mask recommendations in February 2022.

Methods: Student mask policies for US states and the District of Columbia, as well as a sample of 56 districts were categorized as prohibited, recommended, or required in September 2021, November 2021, January 2022, and March 2022 based on the Johns Hopkins eSchool+ Initiative School Reopening Tracker.

Pediatric vision screening detects children at risk for visual conditions with the goal of connecting those in need with an eye care provider for evaluation and treatment. The primary aim for vision screening in younger children is the detection of those at risk for amblyopia, which can result in irreversible vision loss if left untreated. In older children, screening goals broaden to include the detection of risk for uncorrected refractive error.
