MedicalResearch.com: What is the background for this study? What types of aromas were employed?
Response: The olfactory system is the only sense to have a direct “superhighway” access to the memory centers of the brain. The other senses can contribute to the health of the memory centers, but they have to take the brain's “side streets” to get there and consequently have much less impact on the health of those centers.
If there is olfactory loss for any reason, the memory centers start to deteriorate. Stimulation of those memory centers with odors allows those centers to allow for better memory.
We used naturally occurring pleasant odors: rose, orange, eucalyptus, lemon, peppermint, rosemary, and lavender.

MedicalResearch.com: What is the background for this study? Would you briefly describe Alpha-gal Syndrome?
Response: Alpha-gal syndrome is an emerging and potentially life-threatening allergic condition that is associated with a tick bite. It is also called alpha-gal allergy, red meat allergy, or tick bite meat allergy.
Increasing case studies and anecdotal reports suggested that AGS was a growing concern, but, prior to these studies, information on clinician awareness and the number of people impacted was not available at a national level.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: The Task Force reviewed the latest available evidence to evaluate whether screening all children and adolescents who are 20 years old or younger for high cholesterol improves their heart health into adulthood.
At this time, there is not enough evidence to determine whether or not screening all kids is beneficial, so we are calling for additional research on the effectiveness of screening and treatment of high cholesterol in kids and teens.

Dr. Callahan studies interactions between mental and physical health across development.
MedicalResearch.com: What is the background for this study?
Response: A growing body of evidence links the gut microbiome to brain and immune functioning, and changes to that community of microorganisms is likely among the ways that hardship affects children’s socioemotional development.
Limited evidence in humans has demonstrated the adversities experienced prenatally and during early life influence the composition of the gut microbiome, but no studies had examined whether stress experienced in a mother's own childhood could influence the microbiome of the next generation of children.

MedicalResearch.com: What is the background for this study?
Response: Microplastics have been detected in various food items and beverages, including table salt, bottled water, fish, and mussels. The extensive use of plastic-based products in food preparation, storage, and handling has raised concerns about the direct release of microplastics. Interestingly, we often discuss microplastics but overlook nanoplastics in the conversation. Due to their smaller size, nanoplastics are harder to be detected.
In our study, we wanted to see the release of both microplastics and nanoplastics, as nanoplastics may be even more toxic than microplastics.
Unfortunately, infants and toddlers are particularly vulnerable to the potential health impacts of micro- and nanoplastics. Studies have shown significant ingestion of these particles from polypropylene feeding bottles and silicone-rubber baby teats. We aimed to investigate the release of of micro- and nanoplastics, estimated their exposure for infants and toddlers, and evaluated their cytotoxicity to human embryonic kidney cells.
MedicalResearch.com: What is the background for this study?
Response: I became interested in dog's sense of smell several years ago while doing therapy dog demonstrations at the California Science Center in Los Angeles during a special traveling exhibit "Dogs! A Science Tail." (Now at the Orlando Science Center). I did a lot of research on this topic and taught children about it through the Los Angeles Public Library using my Great Pyrenees therapy dogs. Then, COVID broke out and I expanded my research into any work being done to possibly utilize scent dogs for screening and testing for COVID. I found only a few such studies. However, I fortuitously met Heather Junqueira of BioScent, Inc. (in Florida) online and she was beginning to successfully teach her beagles to detect COVID-related odors. She agreed to co-author a peer-reviewed review paper with me. That led to our first paper -
Dickey, T, Junqueira, H. Toward the use of medical scent dogs for COVID-19 screening. J Osteopath Med 2021;1(2): 141-148.

MedicalResearch.com: What is the background for this study?
Response: The 2018 Farm Bill authorizing hemp production led to new cannabinoids in the consumer marketplace. As the market becomes increasingly saturated with suppliers, companies continually diversify available products.
The rapid emergence of novel cannabinoids outpaces systematic research necessary to inform regulations and harm reduction. Empirical evidence is needed to guide policies, practices, and education of consumers. Product manufacturers, social media participants, and cannabis oriented on-line news sources have claimed that THC-O-acetate is a "psychedelic" cannabinoid, producing experiences similar to those associated with LSD, psilocybin, mescaline, and DMT.

MedicalResearch.com: What is the background for this study?
Response: Delivery-related mortality in U.S. hospitals has decreased for all racial and ethnic groups, age groups, and modes of delivery while the prevalence of severe maternal mortality (SMM) increased for all patients, with higher rates for racial and ethnic minority patients of any age.
This study specifically looked at inpatient delivery-related outcomes and found a 57% decrease from 2008-2021. The decreasing mortality rates within the inpatient delivery setting demonstrated as statistically significant and a welcome finding for all women.
This study also looked with greater granularity at the impact of race, ethnicity, and age. Mortality for American Indian women decreased 92%, Asian women decreased 73%, Black women decreased 76%, Hispanic women decreased 60%, Pacific Islander women decreased 79%, and White women decreased 40% during the study period.
