IATP/STP Maronpot Guest Lecture Series: Bridging the Gap Between Toxicologic Pathologists and the Medical Device Industry
Speaker: JoAnn Schuh, JCL Schuh PLLC
Wednesday, June 26, 2019
12:30 PM - 1:30 PM
Held during the STP Annual Meeting, Raleigh, NC
This presentation discussed the existing gap between the fields of toxicologic pathology and the medical device industry and the need for toxicologic pathologists to improve this relationship. Biomaterials and medical devices have a long history in the therapeutic intervention for multiple diseases, but safety and efficacy testing of these products has been largely overlooked by toxicologic pathologists. Toxicologic pathologists have the core skills and are ideally suited to provide high-level safety and efficacy assessment of medical device products; however, toxicologic pathologists face limitations due to the lack of formal training or continuing education programs, and a lack of familiarity with types and appearance of biomaterials. Most of the relevant publications/references for the medical device industry are in the bioengineering field and differences exist in terminology, testing standards, and endpoints compared to testing of drugs and biologics. Additionally, the medical device industry has resisted robust safety and efficacy testing, but recent device failures and the increasing complexity of medical devices and combination products is driving a need for improved risk management. The current atmosphere provides an opportunity for toxicologic pathologists to bridge the gap with the medical device industry. Toxicologic pathologists need to become more active as the leaders in establishing nomenclature, best practices, testing standards, and regulations for biomaterials and finished medical devices.

IATP Workshop: Evaluation of stem cell-derived cellular therapy products.
Speaker: Alys Bradley, Charles River Laboratories
June 20, 2018
Held during the STP Annual Meeting, Indianapolis, IN
The lunchtime lecture discussed stem cells and stem cell-derived cellular therapy products and the role of pathologists in evaluating such products. Due to a rapid and expanding interest in stem cell-derived cellular therapeutics, along with medical devices and tissue engineering in the burgeoning field of regenerative medicine, toxicologic pathologists are confronted with evaluating these types of preclinical studies with few guidelines available to help in the design and assessment of such studies. Therefore, we thought it would be timely and of interest to the STP community to have a presentation on stem cell-derived cellular therapy products and approaches to doing toxicologic pathology evaluations of such products. The importance of input from the pathologist on initial study design and addressing issues of appropriate tissue collection, and optimal species and cell marker selection will be addressed. Regulatory issues to be considered in designing and evaluating preclinical studies on stem cell-derived cellular therapy products were also covered.
IATP-Path 2.0 Satellite Symposium: ToxPath21
August 30, 2017
Held at the ESTP Annual Meeting, Lyon, France

IATP Workshop: Application of In Vivo and Ex Vivo Multimodality Imaging in Toxicology and Toxicologic Pathology
November 7, 2016
Held at the ACT Annual Meeting, Baltimore, MD
View the Published Manuscript
Imaging methods are established tools in biomedical basic science research with applications in drug discovery, pathology, and toxicology research. Contemporary imaging tools extend the ability of the toxicologist, and toxicologic pathologist, to comprehensively study whole animal, and tissue structure and function, in tandem with metabolism and distribution of molecules, biomarkers, metabolites, peptides, drugs, etc. and to correlate these chemical events with conventional histology at high resolution. These imaging tools provide for noninvasively conducting longitudinal studies in the same experimental animals, for monitoring gene expression, signal transduction, and tumor growth and therapy, and give us the ability to quantitate multiple tissue lesions in three dimensions. This workshop is offered by the International Academy of Toxicologic Pathology and will provide practical applications of multimodality imaging for toxicologists and toxicologic pathologists. Speakers: Robert Maronpot (Moderator), Kathy Gabrielson, Vyacheslav (Slava) Kalchenko, Yael Schiffenbauer, Abraham Nyska, David Bonnel.

Ethical Figure Adjustments for Publication (Part 2 of Responsible Authorship & Publication Practices
Held at the STP Annual Meeting, June 27, 2012. Boston, MA
View Presentation
Session Overview: Electronic images of graphs, charts, blots, photomicrographs, etc. are typically provided as part of manuscript submissions to journals. With the currently available image adjustment programs, it is relatively easy to modify any of the various figures submitted along with manuscript text for publication in scientific journals. Photomicrographs captured with electronic cameras often need adjustment for white balance and require some sharpening. While global image adjustment changes are generally accepted, other electronic image adjustments are considered unethical. The purpose of this workshop is to present practical approaches and techniques for image adjustment, with emphasis on photomicrographs. Following the 90-minutes presentation, individuals may bring specific questions and problem images for one-on-one interaction with imaging experts.

Session Overview: This one-hour lecture was aimed at toxicologic pathology trainees and consisted of a presentation of a series of non-neoplastic and neoplastic lung lesions. The focus was on lung lesions that would be encountered in typical preclinical toxicology studies. The significance of each lesion was discussed in terms of whether it was relevant for human health risk or was simply a rodent-specific lung change.
IATP Educational Seminar: Pathology of the Rodent Immune System and Its Challenges
Held at the ESTP Meeting, September 7, 2011. Uppsala, Sweden
Session Overview: The immune system is an increasingly important organ system for therapeutic product development and safety assessment of chemicals. It is also one of the more difficult body systems for pathology interpretation and evaluation. Over the past several years, an expanded pathology protocol for the examination of the thymus, spleen, lymph nodes, epithelial-associated lymphoid tissue and bone marrow has been suggested. A half-day session on the pathology of the rodent immune system will review the anatomy and histology of the lymphoid system, by tissue compartments to be also used in lesion diagnosis, lesions in aging mice, interpretation and diagnoses of reactive and neoplastic lesions and aspects of immune system pathology for the development and safety assessment of therapeutic products. Presentations will include immunohistochemistry and other laboratory diagnostic aids. Attendees can bring glass slides or Aperio digital slides to the meeting for consultation by session lecturers.
