The City of Baltimore, MD has a history of problems with environmental justice (EJ), air pollution, and the urban heat island (UHI) effect. Current chemical transport models lack the resolution to simulate concentrations on the scale needed, about 100 m, to identify the neighborhoods with anomalously high air pollution levels. In this paper we introduce the capabilities of a mobile laboratory and an initial survey of several pollutants in Baltimore to identify which communities are exposed to disproportionate concentrations of air pollution and to which species.

Article Synopsis
  • The study utilizes a new measurement technique to analyze different isotopic variants of methane (CH) to understand their origins, specifically from fossil fuels and microbes.
  • The results reveal that the actual composition of atmospheric methane differs from model predictions and highlight a significant microbial contribution that had been underestimated in previous studies.
  • The findings show that isotopologue data can effectively differentiate between various emissions scenarios, despite consistent atmospheric methane concentration profiles and traditional isotopic measurements.

A common misperception is that critically ill patients who receive paralytic therapy will not tolerate enteral nutrition. As a result, some clinicians empirically withhold enteral feedings for critically ill patients who receive neuromuscular blocker pharmacotherapy (NMB). The intent of this review is to examine the evidence regarding enteral feeding tolerance for critically ill patients given NMB.

Transient transfection of mammalian cells using plasmid DNA is a standard method to produce adeno-associated virus (AAV) vectors allowing for flexible and scalable manufacture. Typically, three plasmids are used to encode the necessary components to facilitate vector production; however, a dual-plasmid system, termed pDG, was introduced over 2 decades ago demonstrating two components could be combined resulting in comparable productivity to triple transfection. We have developed a novel dual-plasmid system, pOXB, with an alternative arrangement of sequences that results in significantly increased AAV vector productivity and percentage of full capsids packaged in comparison to the pDG dual design and triple transfection.

Vehicles are a major source of anthropogenic emissions of carbon monoxide (CO), nitrogen oxides (NO), and black carbon (BC). CO and NO are known to be harmful to human health and contribute to ozone formation, while BC absorbs solar radiation that contributes to global warming and also has negative impacts on human health and visibility. Travel restrictions implemented during the COVID-19 pandemic provide researchers the opportunity to study the impact of large, on-road traffic reductions on local air quality.

Background: The purpose of this study was to assess gastric feeding intolerance for critically ill patients who received sustained neuromuscular blocker (NMB) pharmacotherapy.

Methods: Adult patients (>17 years of age) admitted to the trauma intensive care unit who received continuous intravenous NMB pharmacotherapy (rocuronium, cisatracurium, vecuronium, or pancuronium) for ≥48 h during continuous intragastric enteral nutrition (EN) were retrospectively evaluated. Gastric feeding intolerance was defined by initiation of a prokinetic agent (metoclopramide, erythromycin, or both) for an elevated gastric residual volume (GRV) >300 ml and with distention of the abdomen by physical examination, observation of regurgitation or emesis, temporary discontinuation of EN with low intermittent gastric suctioning, or initiation of parenteral nutrition (PN).

Background: This review has been developed following a panel discussion with an international group of experts in the care of patients with obesity in the critical care setting and focuses on current best practices in malnutrition screening and assessment, estimation of energy needs for patients with obesity, the risks and management of sarcopenic obesity, the value of tailored nutrition recommendations, and the emerging role of immunonutrition. Patients admitted to the intensive care unit (ICU) increasingly present with overweight and obesity that require individualized nutrition considerations due to underlying comorbidities, immunological factors such as inflammation, and changes in energy expenditure and other aspects of metabolism. While research continues to accumulate, important knowledge gaps persist in recognizing and managing the complex nutritional needs in ICU patients with obesity.

Nitrogen dioxide (NO) at the ground level poses a serious threat to environmental quality and public health. This study developed a novel, artificial intelligence approach by integrating spatiotemporally weighted information into the missing extra-trees and deep forest models to first fill the satellite data gaps and increase data availability by 49% and then derive daily 1 km surface NO concentrations over mainland China with full spatial coverage (100%) for the period 2019-2020 by combining surface NO measurements, satellite tropospheric NO columns derived from TROPOMI and OMI, atmospheric reanalysis, and model simulations. Our daily surface NO estimates have an average out-of-sample (out-of-city) cross-validation coefficient of determination of 0.
