    Background. The COVID-19 pandemic caused significant psychological distress among U.S. adults leading to increased rates of adverse mental health symptoms and substance use. This study aims to evaluate the consistency of the association between loneliness and increased mental health problems and substance use in Richmond, VA during the COVID-19 pandemic. Methods. Data were collected in two phases: 1) internet-based surveys from August 2020 to March 2021 (N=327) and 2) paper-pencil surveys from May to October 2021 (N=225). Logistic regression was used to test the association between loneliness and increased mental health and substance use, while adjusting for sociodemographic factors and pre-existing mental health conditions. Results. Both survey populations reported a high prevalence of increased loneliness (46.7% - 68.8%), mental health problems (50.2% - 67.3%), and substance use (22.2% - 29.4%) since the COVID-19 pandemic. Increased loneliness since the pandemic was significantly associated with increased mental health problems (Online survey: AOR=5.00, 95% CI=2.56 - 9.97; Paper-pencil survey: AOR=10.48, 95% CI=4.18 - 28.59) and increased substance use (Online survey: AOR=3.14, 95% CI=1.58 - 6.60; Paper-pencil survey: AOR=5.89, 95% CI=1.97 - 19.71). Conclusions. The association between increased loneliness and increased mental health problems and substance use during COVID-19 in Richmond, Virginia was consistent across the two survey populations and similar to the rest of the U.S

    Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) immune responses and infection outcomes were evaluated in 2,686 patients with varying immune-suppressive disease states after administration of two Coronavirus Disease 2019 (COVID-19) vaccines. Overall, 255 of 2,204 (12%) patients failed to develop anti-spike antibodies, with an additional 600 of 2,204 (27%) patients generating low levels (<380 AU ml−1). Vaccine failure rates were highest in ANCA-associated vasculitis on rituximab (21/29, 72%), hemodialysis on immunosuppressive therapy (6/30, 20%) and solid organ transplant recipients (20/81, 25% and 141/458, 31%). SARS-CoV-2-specific T cell responses were detected in 513 of 580 (88%) patients, with lower T cell magnitude or proportion in hemodialysis, allogeneic hematopoietic stem cell transplantation and liver transplant recipients (versus healthy controls). Humoral responses against Omicron (BA.1) were reduced, although cross-reactive T cell responses were sustained in all participants for whom these data were available. BNT162b2 was associated with higher antibody but lower cellular responses compared to ChAdOx1 nCoV-19 vaccination. We report 474 SARS-CoV-2 infection episodes, including 48 individuals with hospitalization or death from COVID-19. Decreased magnitude of both the serological and the T cell response was associated with severe COVID-19. Overall, we identified clinical phenotypes that may benefit from targeted COVID-19 therapeutic strategies

    This project's goal was to improve the ASSISTments intelligent tutoring system's algebraic capabilities. We worked towards three main objectives. First, we built support for parsing expressions and comparing them for algebraic equality. Second, we implemented an interactive grapher capable of plotting a variety of expressions. Third, we added support for rendering expressions to well formatted images. Finally, we implemented a basic tutoring system including sample problems that demonstrate our work, establishing our tools' usability and integrability

    Mapping and Evaluating Carbon Dioxide Reduction in Merton

    Get PDF
    In effort to reduce its carbon dioxide emissions, the London Borough of Merton hopes to identify all municipal activities that directly create or indirectly affect CO2 emissions, and map these activities to the departments responsible for them.  This project assists that goal by initializing the identification process, creating a database framework to house the list of potential reduction measures for each activity, and developing methods for rating each measure's implementation and financial feasibility.

    Review of Mindfulness-Related Interventions to Modify Eating Behaviors in Adolescents

    No full text
    There are few well-established treatments for adolescent eating disorders, and for those that do exist, remission rates are reported to be between 30 and 40%. There is a need for the development and implementation of novel treatment approaches. Mindfulness approaches have shown improvements in eating disorder-related psychopathology in adults and have been suggested for adolescents. The present review identifies and summarizes studies that have used mindfulness approaches to modify eating behaviors and to treat eating disorders in adolescents. Focused searches were conducted in Embase, Medline, and PsycINFO, and identified articles were checked for relevance. A small number of studies (n = 15) were designated as appropriate for inclusion in the review. These studies were divided into those that focused on the promotion of healthy eating/the prevention of disordered eating (n = 5), those that concentrated on targeted prevention among high risk adolescents (n = 5), and those that focused on clinical eating disordered adolescents (n = 5). Thirteen of the 15 studies reviewed reported at least one positive association between mindfulness treatment techniques and reduced weight/shape concerns, dietary restraint, decreased body mass index (BMI), eating in the absence of hunger (EAH), binge eating, increased willingness to eat novel healthy foods, and reduced eating disorder psychopathology. In summary, incorporating mindfulness to modify eating behaviors in adolescent non-clinical and clinical samples is still in the early stages, with a lack of data showing clear evidence of acceptability and efficacy. Further studies and preferably controlled conditions are warranted

    Thioredoxin suppresses microscopic hopping of T7 DNA polymerase on duplex DNA

    The DNA polymerases involved in DNA replication achieve high processivity of nucleotide incorporation by forming a complex with processivity factors. A model system for replicative DNA polymerases, the bacteriophage T7 DNA polymerase (gp5), encoded by gene 5, forms a tight, 1∶1 complex with Escherichia coli thioredoxin. By a mechanism that is not fully understood, thioredoxin acts as a processivity factor and converts gp5 from a distributive polymerase into a highly processive one. We use a single-molecule imaging approach to visualize the interaction of fluorescently labeled T7 DNA polymerase with double-stranded DNA. We have observed T7 gp5, both with and without thioredoxin, binding nonspecifically to double-stranded DNA and diffusing along the duplex. The gp5/thioredoxin complex remains tightly bound to the DNA while diffusing, whereas gp5 without thioredoxin undergoes frequent dissociation from and rebinding to the DNA. These observations suggest that thioredoxin increases the processivity of T7 DNA polymerase by suppressing microscopic hopping on and off the DNA and keeping the complex tightly bound to the duplex

    MitoNEET (CISD1) Knockout Mice Show Signs of Striatal Mitochondrial Dysfunction and a Parkinson\u27s Disease Phenotype

    Mitochondrial dysfunction is thought to play a significant role in neurodegeneration observed in Parkinson’s disease (PD), yet the mechanisms underlying this pathology remain unclear. Here, we demonstrate that loss of mitoNEET (CISD1), an iron–sulfur containing protein that regulates mitochondrial bioenergetics, results in mitochondrial dysfunction and loss of striatal dopamine and tyrosine hydroxylase. Mitochondria isolated from mice lacking mitoNEET were dysfunctional as revealed by elevated reactive oxygen species (ROS) and reduced capacity to produce ATP. Gait analysis revealed a shortened stride length and decreased rotarod performance in knockout mice, consistent with the loss of striatal dopamine. Together, these data suggest that mitoNEET KO mice exhibit many of the characteristics of early neurodegeneration in PD and may provide a novel drug discovery platform to evaluate compounds for enhancing mitochondrial function in neurodegenerative disorders
