Response: Our study describes a surprising link between an intestinal infection with a common virus, human cytomegalovirus (HCMV), and the development of Alzheimer’s in a subset of people with the disease.
In a study published earlier this year in the journal Nature Communications, we found that research participants with Alzheimer’s disease were more likely than those without it to harbor a particular immune cell type (“CD83(+) microglia”) in their brains. While trying to uncover what might be driving the presence of these CD83(+) microglia, we discovered an antibody (IgG4) in the intestine of these same subjects that were suggestive of the possibility that some kind of infection might contribute to this form of the disease.

MedicalResearch.com: What is the background for this study?
Response: Opioid use has been an increasing problem since the early 2000s in the United States (US) with a surge around 2010. Twenty-five percent of those having abused pain relievers in 2013 and 2014 got those drugs from physicians1. Physicians are particularly well-known for fueling the opioid crisis in Florida in the 2000s. Of the United States’ top 100 opioid prescribing physicians in 2010, an astounding 98 were prescribing in Florida2. Florida taking the main stage of the opioid crisis can be attributed to several factors, including ability of physicians to dispense opioids directly from their offices to patients (i.e. without pharmacists) and the presence of many infamous “pill mills” in the state3–6.
The researchers at Geisinger Commonwealth School of Medicine aimed to analyze the amount of hydrocodone (including brand names of Vicodin and Lortab) and oxycodone (OxyContin and Percocet) distributed in Florida from 2006 to 2021, paying close attention to the peak year of the opioid crisis, 2010. The team used the Washington Post and the US Drug Enforcement Administration’s Automation of Reports and Consolidated Orders System (ARCOS) databases to compile this compelling information.

Response: Previous observational studies have shown that urinary BPA is related to Type 2 diabetes risk. Meaning, higher urinary BPA is related to an increased risk of Type 2 diabetes. However, no published study to date has determined whether several days of BPA administration (participants consume BPA) increases the risk of Type 2 diabetes.
MedicalResearch.com: Where is bisphenol found? Can exposure to bisphenol be limited in everyday life?
Response: BPA and other bisphenols are found in canned foods and plastics. BPA is one of the most widely used synthetic chemicals and we consume foods that are packed in this chemical. Most of BPA exposure comes from canned foods, and 93% of the US populations has detectable urine levels of BPA. We can limit BPA by reducing canned foods (or purchased BPA free cans) and plastic use.
