Tailored vs. General COVID-19 prevention for adults with mental disabilities residing in group homes: a randomized controlled effectiveness-implementation trial.

Background: People with serious mental illness (SMI) and people with intellectual disabilities/developmental disabilities (ID/DD) are at higher risk for COVID-19 and more severe outcomes. We compare a tailored versus general best practice COVID-19 prevention program in group homes (GHs) for people with SMI or ID/DD in Massachusetts (MA).

Methods: A hybrid effectiveness-implementation cluster randomized control trial compared a four-component implementation strategy (Tailored Best Practices: TBP) to dissemination of standard prevention guidelines (General Best-Practices: GBP) in GHs across six MA behavioral health agencies.

Predictors of COVID-19 infection and hospitalization in group homes for individuals with intellectual and/or developmental disabilities.

Background: More than seven million people with intellectual and/or developmental disabilities (ID/DD) live in the US and may face an elevated risk for COVID-19.

Objective: To identify correlates of COVID-19 and related hospitalizations among people with ID/DD in group homes in Massachusetts.

Methods: We collected data during March 1, 2020-June 30, 2020 (wave 1) and July 1, 2020-March 31, 2021 (wave 2) from the Massachusetts Department of Public Health and six organizations administering 206 group homes for 1035 residents with ID/DD.

CeO nanoparticle dose and exposure modulate soybean development and plant-mediated responses in root-associated bacterial communities.

Agricultural soils are increasingly undergoing inadvertent and purposeful exposures to engineered CeO nanoparticles (NPs), which can impact crops and root-associated microbial communities. However, interactions between NP concentration and exposure duration on plant-mediated responses of root-associated bacterial communities are not well understood. Soybeans seedlings were grown in soil with uncoated NPs added at concentrations of 0, 1 or 100 mg kg.

The experience of fathers of children hospitalised with advanced heart disease.

Background: There are little reported data on the perspectives of fathers caring for children with chronic conditions. Although survival of children with advanced heart disease has improved, long-term morbidity remains high. This study describes the experience and prognostic awareness of fathers of hospitalised children with advanced heart disease.

The family burden of paediatric heart disease during the chronic phase of illness.

Background: CHD is a lifelong condition with a significant burden of disease to patients and families. With increased survival, attention has shifted to longer-term outcomes, with a focus on social determinants of health. Among children with CHD, socioeconomic status is associated with disparities in outcomes.

The authors analyzed data on 2261 group home residents and COVID-19 data from the Massachusetts Department of Public Health. Outcomes included positive COVID-19 tests and COVID-19 hospitalizations March 1, 2020-June 30, 2020 (wave 1) and July 1, 2020-March 31, 2021 (wave 2).

Using eRNA/eDNA metabarcoding to detect community-level impacts of nanoplastic exposure to benthic estuarine ecosystems.

Plastic particles are ubiquitous in marine systems and fragment into smaller pieces, such as nanoplastics (NPs). The effects of NPs on marine organisms are of growing concern but are not well understood. Marine sediments act as a sink for many contaminants, like microplastics, and are rich habitats for benthic micro- and meiofauna which are ecologically-important components of marine food webs; however, little is known about the sensitivities of specific organisms to NPs or the effects on community diversity and composition.

Living with Congenital Aortic Stenosis: Exercise Restriction, Patterns of Adherence, and Quality of Life.

Modern consensus panel guidelines recommend restriction from most organized sports for patients with moderate or severe aortic stenosis (AS). However, there is little published data on how frequently physicians deviate from guidelines, how well patients adhere to exercise restrictions, or the effect of restriction on patient-reported quality of life. In this study, we surveyed 93 subjects with AS and their cardiologists regarding participation in organized sports, physical activity, weightlifting, and exercise restriction.

Environmental RNA as a Tool for Marine Community Biodiversity Assessments.

Microscopic organisms are often overlooked in traditional diversity assessments due to the difficulty of identifying them based on morphology. Metabarcoding is a method for rapidly identifying organisms where Environmental DNA (eDNA) is used as a template. However, legacy DNA is problematically detected from organisms no longer in the environment during sampling.

Focused Microbiome Shifts in Reconstructed Wetlands Correlated with Elevated Copper Concentrations Originating from Micronized Copper Azole-Treated Wood.

Micronized copper (Cu) azole (MCA) wood preservative formulations include Cu in nano form, and relatively little is known about longer term effects of Cu leached from MCA into wetland ecosystems. We tested the hypothesis that changes in soil microbiomes within reconstructed freshwater wetlands will be associated with exposure to elevated Cu concentrations originating from immersed MCA-treated wood stakes. Eight replicate communities were assembled with Willamette Valley (OR, USA) flood plain soil and clonally propagated wetland plants within mesocosms.

Parent-Reported Symptoms and Perceived Effectiveness of Treatment in Children Hospitalized with Advanced Heart Disease.

Objective: To characterize parent-reported symptom burden and effectiveness of symptom management in children hospitalized with advanced heart disease.

Study Design: Prospective survey study of 161 parents whose child was admitted to a single institution with advanced heart disease between March 2018 and February 2019 using the Survey about Caring for Children with Heart Disease.

Results: Of the 161 patients, 54% were under 2 years old with a diagnosis of single ventricle physiology (39%), pulmonary hypertension (12%), and other congenital heart disease (28%).

Transformation and release of micronized Cu used as a wood preservative in treated wood in wetland soil.

Micronized Cu (μ-Cu) is used as a wood preservative, replacing toxic chromated copper arsenate (CCA). Micronized Cu is malachite [CuCO(OH)] that has been milled to micron/submicron particles, with many particle diameters less than 100 nm, mixed with biocides and then used to treat wood. In addition to concerns about the fate of the Cu from μ-Cu, there is interest in the fate of the nano-Cu (n-Cu) constituents.

Assessment of Compassion in Physician Assistant Students.

Purpose: It has been shown that empathy erodes in the later phases of education of both medical students and physician assistant (PA) students. This brief study assessed compassion in PA students at different levels of training to explore if a similar phenomenon occurs.

Methods: Students at entry, midway, and at the end of PA training were surveyed using Pommier's Compassion Scale.

Systemic ventricular assist device support in Fontan patients: A report by ACTION.

Background: The size of the Fontan population with end-stage heart failure is growing. In this population, heart transplantation has been the only option. This study sought to investigate the efficacy of ventricular assist device (VAD) support in Fontan patients.

Parent and Physician Understanding of Prognosis in Hospitalized Children With Advanced Heart Disease.

Background The unpredictable trajectory of pediatric advanced heart disease makes prognostication difficult for physicians and informed decision-making challenging for families. This study evaluated parent and physician understanding of disease burden and prognosis in hospitalized children with advanced heart disease. Methods and Results A longitudinal survey study of parents and physicians caring for patients with advanced heart disease age 30 days to 19 years admitted for ≥7 days was performed over a 1-year period (n=160 pairs).

Tocilizumab among patients with COVID-19 in the intensive care unit: a multicentre observational study.

Background: Tocilizumab, a monoclonal antibody directed against the interleukin-6 receptor, has been proposed to mitigate the cytokine storm syndrome associated with severe COVID-19. We aimed to investigate the association between tocilizumab exposure and hospital-related mortality among patients requiring intensive care unit (ICU) support for COVID-19.

Methods: We did a retrospective observational cohort study at 13 hospitals within the Hackensack Meridian Health network (NJ, USA).

Incidence and Predictors of Clinically Important and Dangerous Arrhythmias During Exercise Tests in Pediatric and Congenital Heart Disease Patients.

Objectives: This study quantified the incidence of arrhythmias during pediatric exercise stress tests (ESTs) and evaluated criteria to identify patients at risk of clinically important arrhythmias.

Background: The incidence of clinically important arrhythmias during pediatric ESTs and criteria for identifying high-risk patients are poorly characterized.

Methods: A retrospective review of ESTs performed from 2013 to 2015 was studied.

Douglas-Fir ( Pseudotsuga menziesii (Mirb.) Franco) Transcriptome Profile Changes Induced by Diesel Emissions Generated with CeO Nanoparticle Fuel Borne Catalyst.

It is important to understand molecular effects on plants exposed to compounds released from use of products containing engineered nanomaterials. Here, we present mRNA sequencing data on transcriptome impacts to Douglas-fir following 2 weeks of sublethal exposure to 30:1 diluted airborne emissions released from combustion of diesel fuel containing engineered CeO nanoparticle catalysts (DECe). Our hypothesis was that chamber exposure to DECe would induce distinct transcriptome changes in seedling needles compared with responses to conventional diesel exhaust (DE) or filtered DECe Gas Phase.

The U.S. Culture Collection Network Responding to the Requirements of the Nagoya Protocol on Access and Benefit Sharing.

The U.S. Culture Collection Network held a meeting to share information about how culture collections are responding to the requirements of the recently enacted Nagoya Protocol on Access to Genetic Resources and the Fair and Equitable Sharing of Benefits Arising from their Utilization to the Convention on Biological Diversity (CBD).

A comprehensive framework for evaluating the environmental health and safety implications of engineered nanomaterials.

Engineered nanomaterials (ENM) are a growing aspect of the global economy, and their safe and sustainable development, use, and eventual disposal requires the capability to forecast and avoid potential problems. This review provides a framework to evaluate the health and safety implications of ENM releases into the environment, including purposeful releases such as for antimicrobial sprays or nano-enabled pesticides, and inadvertent releases as a consequence of other intended applications. Considerations encompass product life cycles, environmental media, exposed populations, and possible adverse outcomes.

Molecular and physiological responses to titanium dioxide and cerium oxide nanoparticles in Arabidopsis.

Changes in tissue transcriptomes and productivity of Arabidopsis thaliana were investigated during exposure of plants to 2 widely used engineered metal oxide nanoparticles, titanium dioxide (nano-titania) and cerium dioxide (nano-ceria). Microarray analyses confirmed that exposure to either nanoparticle altered the transcriptomes of rosette leaves and roots, with comparatively larger numbers of differentially expressed genes found under nano-titania exposure. Nano-titania induced more differentially expressed genes in rosette leaves, whereas roots had more differentially expressed genes under nano-ceria exposure.

Separate introns gained within short and long soluble peridinin-chlorophyll a-protein genes during radiation of Symbiodinium (Dinophyceae) clade A and B lineages.

Here we document introns in two Symbiodinium clades that were most likely gained following divergence of this genus from other peridinin-containing dinoflagellate lineages. Soluble peridinin-chlorophyll a-proteins (sPCP) occur in short and long forms in different species. Duplication and fusion of short sPCP genes produced long sPCP genes.

Phenotypic and genomic responses to titanium dioxide and cerium oxide nanoparticles in Arabidopsis germinants.

The effects of exposure to nanoparticles of titanium dioxide (nano-titanium) and cerium oxide (nano-cerium) on gene expression and growth in Arabidopsis thaliana germinants were studied by using microarrays and quantitative real-time polymerase chain reaction (qPCR), and by evaluating germinant phenotypic plasticity. Exposure to 12 d of either nano-titania or nano-ceria altered the regulation of 204 and 142 genes, respectively. Genes induced by the nanoparticles mainly include ontology groups annotated as stimuli responsive, including both abiotic (oxidative stress, salt stress, water transport) and biotic (respiratory burst as a defense against pathogens) stimuli.
