    In this podcast, recent findings from toxicological studies on the emissions produced during fused filament fabrication (FFF) 3D printing are discussed. The use of low-cost FFF 3D printers is on the rise in households, businesses, and educational settings, enabling the creation of 3D objects from digital models. However, this process releases volatile organic compounds, ultrafine particles, and metal oxides, which could potentially pose health risks to users. Of significant concern is the potential harm to children, who may be disproportionately affected due to uncontrolled exposure to ultrafine particles in confined spaces, such as classrooms and libraries. Dr. Kyle Mandler comprehensively addresses the characteristics and human health effects of these FFF 3D printer emissions and propose effective recommendations for mitigating exposure to these emissions.

    Discussions on Identifying Seizures Liability in Nonclinical Studies

    Play Episode Listen Later Jul 1, 2024 25:27


    Drug-induced seizures are a major concern for central nervous system active pharmaceuticals during development. Currently, there are no guidelines for interrogating and mitigating seizure liability associated with new pharmaceuticals. Because of the risks to patient safety during clinical trials, the understanding of nonclinical characterization that informs the translation of risks to humans is an area of intense interest among drug developers and regulators. A Continuing Education course was held at the 2022 ACT Annual Meeting in Denver, Colorado, where Dr. Delatte presented on identifying seizure liability in nonclinical studies. In this interview with Dr. Delatte, we discuss nonclinical findings that are indicative of seizure liability and appropriate approaches to characterize risks. Many drug classes carry seizure liability which may trigger preliminary studies, such as kindling studies, to understand risks prior to conducting a repeat-dose toxicology study. A description of premonitory signs of seizure in dose-range findings and repeat-dose toxicology studies is also discussed. Finally, this talk briefly discusses when nonclinical EEG studies are warranted and how to leverage the data from general toxicology studies to design an informative EEG study. Learning objectives of this talk are: (1) set up a drug development program for drugs in a class with seizure liability; (2) identify seizure liability in nonclinical studies; and (3) examine the elements from general toxicology studies that inform the pivotal EEG study.

    Covid-19 Part 2: New Type of Antibody-Dependent Enhancement Associated with SARS-CoV-2 Virus: MIS-C, MIS-A, and MIS-N

    Play Episode Listen Later Mar 3, 2023 23:48


    The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes Coronavirus Disease 2019 (COVID-19), Multisystem Inflammatory Syndrome in Children (MIS-C), Adults (MIS-A), Neonates (MIS-N), and some Vaccinees (MIS-V). These are all considered clinically distinct diseases; however, the MIS-X diseases have overlapping symptoms and treatments with Kawasaki Disease (KD). MIS-C, MIS-A, MIS-N, and KD occur with increased frequencies several weeks following increased numbers of COVID-19 and for KD other pathogens. The incidence rate for MIS-C, MIS-A, MIS-N, and KD are typically a factor of roughly 5,000 lower than COVID-19 and for KD other pathogens. In this podcast, Dr. Darrell Ricke advances the hypothesis that MIS-C, MIS-A, MIS-N, MIS-V, and KD all represent a novel type of antibody-dependent enhanced (ADE) diseases associated with hyperactivation of granulocytes or mast cells. Symptoms for these diseases overlap those of histamine intolerance (HIT) coupled with pathogen associated symptoms. This ADE model proposes that antibody titer levels higher than primary immune response levels can hyperactivate granulocytes or mast cells to release inflammatory molecules including histamine; MIS-X and KD disease symptoms onset when histamine levels exceed the individual's tolerance level. The proposed ADE model purports that patient treatment with intravenous immunoglobulin (IVIG) is successful in treating the MIS-X disease because IVIG compete with pathogen antibodies for binding to Fc receptors on immune cells, thereby reducing the immune responses to the pathogen or vaccine protein. This model is further supported with the vaccine spike protein activating immune cells via envisioned Fc receptor binding. This ADE model proposes additional antihistamine and diamine oxidase (DAO) adjunctive treatments combined with current standard of care treatments for investigation.

    Covid-19 Part 1: Antibody-dependent Enhancement of Disease

    Play Episode Listen Later Jan 6, 2023 33:35


    The severity of COVID-19 varies by individual spanning from asymptomatic, mild, moderate, severe, critical, and chronic disease. Prior to the availability of vaccines, high antibody titers correlated with disease severity. This was also observed for SARS disease. These high antibody titers on initial infections result from memory B cell responses with cross-reactive antibody responses from previous infection of likely other betacoronavirus family members. In general, family members of the betacoronavirus family leverage Fc receptor antibody uptake of viruses by phagocytic cells to infect these innate immune cells. This extended cellular tropism of phagocytic immune cells is dependent upon Fc receptors and antibodies. It is hypothesized that SARS-CoV-2 with higher antibody titers can infect phagocytic immune cells; SARS-CoV-2 infection of these cells has been observed in some patients with severe COVID-19. This proposed antibody-dependent enhancement (ADE) of disease has been proposed to a key transition of infection from respiratory infection to multi-organ disease in some severe COVID-19 patients. While the main medical community believes that there is no ADE associated with SARS-CoV-2 infections, multiple clinical studies are consistent with SARS-CoV-2 infection of monocytes and macrophages in some severe COVID-19 patients. The podcast discusses data available in the summer of 2022.
