(Press-News.org) DETROIT — A new grant will help Wayne State University researchers explore the links between bacterial infections, the environmental factors that increase their susceptibility and the risk of preterm birth.
The five-year, $2,858,821 grant from the National Institute of Environmental Health Sciences of the National Institutes of Health, “PFAS increases susceptibility to infection-mediated preterm birth,” will be led by Michael Petriello, Ph.D., assistant professor in Wayne State’s Institute of Environmental Health Sciences and Pharmacology in the School of Medicine.
Petriello hopes that the team’s studies will identify critical pathways responsible for preterm birth and establish a causative link between pollutant exposures and adverse birth outcomes. He said Wayne State’s collaborative atmosphere made the study possible.
“When I came to Wayne State five years ago, I was looking for interdisciplinary collaborators and I saw how strong this university is in terms of preterm birth studies and expertise,” said Petriello. “Dr. Gil Mor has done some great work on the subject, and he was focusing mainly on viruses. We’ve initiated the collaboration with the C.S. Mott Center for Human Growth and Development thanks to studies by our Superfund Research Center, CLEAR (The Center for Leadership in Environmental Awareness and Research), related to benzine exposure in preterm births. Now we’re all pooling our expertise to explore new avenues on this subject.”
Petriello and his collaborators hypothesize that pollutant exposures, particularly per-and poly fluoroalkyl substances (PFAS), can increase the susceptibility to bacterial infection and increase preterm birth risk, resulting in children being born too early and potentially leading to severe health issues or even death.
“We hope to find links between PFAS exposure in mothers and preterm birth, focusing on the placenta as a major target of PFAS toxicity,” said Petriello. “We think it is an under-studied organ in terms of PFAS exposure. What we are doing that is novel is using spatial transcriptomics, which looks at different regions of the placenta to see which cell types are affected by the PFAS. We also want to look at bacterial infection as a factor in preterm birth to see if PFAS exposure increases that likelihood of infection.”
This complex research requires an interdisciplinary team including additional faculty at Wayne State with expertise in maternal and fetal health (Dr. Gil Mor), genomics (Drs. Doug Ruden and Katherine Gurdziel) and chemistry (Dr. Charlie Fehl).
“In order to solve many of the problems in our community, such as preterm birth, we need more of this type of collaborative work between experts in different fields,” said Gil Mor, M.D., the scientific director of the C.S. Mott Center for Human Growth and Development. “Dr. Petriello is an outstanding environmental science scientist. My interest has been how the placenta responds to infections, but it has always been a challenge to us that some women would respond to changes in the environment and others don’t. Some had major complications during COVID, and others weren’t affected at all, for instance. We are creating animal models to study these environmental effects on pregnancy. I originally came to Detroit because it is the capital in the United States, unfortunately, for preterm birth, and there was strong chance that this high rate was because of environmental factors.”
“The link between a community’s environment and its health is crucial,” said Ezemenari M. Obasi, Ph.D., vice president for research & innovation at Wayne State University. “This important study led by Dr. Petriello will provide new knowledge on this topic and offer new ideas to improve people’s lives.”
The award number for this grant from the National Institute of Environmental Health Sciences of the National Institutes of Health is ES035692.

Antimicrobial resistance is a growing threat.
Bacteria exchange AMR genes in the gut via circular genetic material called plasmids.
In lab experiments, bacteria transferred plasmids with AMR genes in the presence of zinc at reduced or nonexistent rates.
Stopping the transfer without killing microbes may help reduce AMR without disrupting the gut microbiome.

On October 3, 2024, NASA announced that two space probes proposed by University of Maryland astronomers have advanced to the next round of consideration for a $1 billion mission slated to launch into orbit in 2032.
The selected probes include the Advanced X-ray Imaging Satellite (AXIS) mission with UMD Astronomy Professor Christopher Reynolds as its principal investigator and the PRobe far-Infrared Mission for Astrophysics (PRIMA) with UMD Astronomy Professor Alberto Bolatto as a co-investigator and NASA Goddard Space Flight Center researcher and UMD Astronomy ...

EAST LANSING, Mich. – In recent years, some states have prioritized purging their voter rolls of those who have passed away or moved out of state. During election season, there is often increased discussion about the necessity and impact of these actions. Voter purging can be an important step for creating election integrity, but others have raised concerns about how the process is conducted and who it targets.
So, are there negative effects of voter purging? Researchers from Michigan State University wanted to find out — especially ...
In this study, the Cancer Research UK-funded scientists will establish the targets for the vaccine. They will find out which proteins on the surface of early-stage ovarian cancer cells are most strongly recognised by the immune system and how effectively the vaccine kills mini-models of ovarian cancer called organoids.
If this research is successful, work will then begin on clinical trials of the vaccine. The hope is that in the future, women could be offered this vaccine to prevent ovarian cancer in the first place.
There are around 7,500 new ovarian ...
COLUMBUS, Ohio – Researchers have developed a way to make one type of plastic material more durable and less likely to shed dangerous microplastics.
The study identified a secure way to attach chemical additives to polyvinyl chloride (PVC).
Found in everything from toys, construction supplies and medical packaging, PVC plastics currently rank third among the most used plastics worldwide. Despite its widespread use, pure PVC is brittle and sensitive to heat, and manufacturers can only utilize it after stabilizing its properties with other chemicals.
However, these additives, or plasticizers, ...
Houston Methodist researchers will be part of a national consortium funded by an up to $49 million award from the U.S. Government’s Advanced Research Projects Agency for Health (ARPA-H) to develop a vaccine against two of the most common and destructive strains of herpesviruses that latently infect a majority of Americans and can lead to acute infections, multiple forms of cancer, autoimmune disease and birth defects.
The award is part of ARPA-H’s Antigens Predicted for Broad Viral Efficacy through Computational Experimentation (APECx) program and will fund the America’s SHIELD project ...
SAN ANTONIO, Oct. 3, 2024 – The School of Dentistry at The University of Texas Health Science Center at San Antonio (UT Health San Antonio) earned the first National Institutes of Health grant under its new Center for Pain Therapeutics and Addiction Research, addressing pain in patients with head and neck carcinoma.
The nearly $600,000 grant by the NIH’s National Institute of Dental and Craniofacial Research will address this critical pain issue that significantly impairs quality of life. Many head and neck carcinoma patients require opiate pain management, but tolerance develops quickly, requiring new pain ...
Public health degree programs provide key competencies demanded by employers, but graduate employability could be improved by using more real-time data from employer job postings, according to a new study at Columbia University Mailman School of Public Health. This could help public health schools and programs ensure that graduates obtain specific technical skills listed in job postings, meet current employer needs, and prepare graduates for the demands of today’s labor market. The findings are published in the American Journal of Public Health.
The competencies required for the ...
Since the 2020 murder by Minneapolis police of George Floyd brought nationwide calls for change amid concerns that prevailing practices were not grounded in evidence and created harm, policing has been in turmoil. Implementation science (IS) involves integrating effective and evidence-based innovations into routine practice in fields like health care. Yet despite its potential, IS—and specifically, evidence-based policing (EBP)—remain vastly understudied and unused in police settings. In a new article, researchers provide an orientation to these issues ...
