Per- and poly-fluoroalkyl substances (PFAS) are a class of compounds utilized in a variety of industrial and commercial applications, such as firefighting foams and military equipment. Recent research has raised concerns about the possible health implications of PFAS exposure, specifically its association with testicular cancer. Firefighters and military personnel are particularly vulnerable owing to work exposure to PFAS-containing chemicals. This article explores the connection between PFAS exposure and testicular cancer, focusing on the impact on firefighters and military personnel. It will also discuss the legal recourse available for these individuals through AFFF lawsuits. (more…)
Author Interviews, Environmental Risks, Thyroid / 27.10.2023

MedicalResearch.com Interview with: Maaike van Gerwen, MD, PhD Assistant Professor Department of Otolaryngology- Head and Neck Surgery Institute for Translational Epidemiolog Director of Research Department of Otolaryngology- Head and Neck Surgery Icahn School of Medicine at Mount Sinai MedicalResearch.com: What is the background for this study? Where are these PFAS chemicals found? Response: Over the past decades, we have seen an increasing trend in thyroid cancer which cannot be fully explained by increased use of medical imaging (including ultrasound). Certain environmental exposure are known to impact on the thyroid gland, including thyroid dysfunction or development of cancer. PFAS are chemicals that are known to disrupt the function of endocrine organs, such as the thyroid gland. We therefore hypothesized that PFAS exposure may be one of the potential risk factors for thyroid cancer and thus one of the potential reason for the increasing thyroid cancer incidence. PFAS chemicals are widespread in the environment and have been found in the soil, water, and air. PFAS are also widely used in a variety of consumer products including non-stick cookware, stain resisting fabric, firefighting foams, but are also found in drinking water and food. This leads to an almost universal exposure of the general population. (more…)
Author Interviews, Endocrinology, Environmental Risks / 23.02.2023

MedicalResearch.com Interview with: Jesse Goodrich PhD Assistant Professor Department of Population and Public Health Sciences Keck School of Medicine University of Southern California MedicalResearch.com: What is the background for this study? Response: Per- and poly-fluoroalkyl substances (PFAS) are a group of persistent chemicals that are known to interfere with hormones and metabolism. In our previous research, we have found that PFAS exposure is associated several specific diseases, especially in children and adolescents. These include obesity, type 2 diabetes, liver disease, and even liver cancer. However, we are still only just starting to fully understand all of the health effects of the many different PFAS in existence. Previous studies have focused primarily on one or two main PFAS. However, there are over 9,000 known PFAS, and people are exposed not just to a single PFAS but to mixtures of many PFAS. Importantly, the combination of these chemical exposures may affect us differently than single exposures alone. To address this challenge, we used an innovative approach to study design to examine how exposure to PFAS impacts biological processes which may underly the development of many different diseases in adolescents and young adults. To do this, we first measured thousands of naturally occurring chemicals, known as metabolites, in people's blood. Then, using a new biostatistical method developed by our team, we identified how exposure to a mixture of several PFAS impacted each individual chemical. Finally, we used this information to determine which biological processes are changed by PFAS exposure. (more…)
Author Interviews, Environmental Risks, Hepatitis - Liver Disease / 27.04.2022

MedicalResearch.com Interview with: Sarah Rock, MPH PhD student, Department of Population and Public Health Sciences Keck School of Medicine University of Southern California MedicalResearch.com:  What is the background for this study?  What are the main findings?  Response: Per- and polyfluoroalkyl substances (PFAS) are persistent, man-made chemicals widely used in industry and consumer products. Exposure to these chemicals has been linked to multiple disease outcomes including cancer, glucose dysregulation, and as reported in the current study, liver injury. We compiled results from more than 100PFAS studies in humans and rodents and found consistent evidence that PFAS are related to liver injury. (more…)

MedicalResearch.com Interview with: Ning Ding MPH, PhD candidate Sung Kyun Park Sc.D, MPH Associate Professor Department of Epidemiology University of Michigan School of Public Health Ann Arbor, MI 48109  MedicalResearch.com: What is the background for this study? Response: Per- and polyfluoroalkyl substances (PFAS), also known as ‘forever chemicals’, are a family of synthetic chemicals used in a wide variety of nonstick and waterproof products and firefighting foams. The main issue is that PFAS are everywhere. It has been estimated that 110 million Americans, 1 out of three, may consume drinking water contaminated with PFAS. PFAS are very persistent and once PFAS enter the body, they don't break down and build up in the body over time. (more…)
