Response: NAD+, a central cellular energy and signaling molecule, declines with age throughout the body, including the brain. When NAD+ falls below necessary levels, cells lose their ability to carry out essential maintenance and survival functions. We found that the NAD+ decline is more severe in brains from people with Alzheimer’s disease (AD) and in mouse models of AD, whereas brains of people with AD pathology but preserved cognition show gene-expression patterns consistent with maintained NAD+ homeostasis.

Response: Microplastics are tiny plastic particles less than 5 mm which have become a pervasive environmental pollutant, detectable in air, water, food, and even human tissues. While their ecological impacts have been well-documented, their influence on human health, particularly cardiovascular health, remains underexplored. Recent mechanistic studies suggest that microplastics can induce inflammation, oxidative stress, and endothelial dysfunction, all of which are pathways implicated in chronic disease and ASCVD. In our study, we analyzed a total of 709 U.S. coastal census tracts to investigate the association between marine microplastic concentration data obtained from NOAA NCEI database and the prevalence of stroke and other chronic non-communicable diseases (NCDs) such as high blood pressure and diabetes, sourced from CDC places database.

Response: 75% of the US Population has overweight or obesity and 15% has Type 2 Diabetes. Both overweight/obesity and diabetes promote increased incidence and worse prognosis of colorectal cancer. The new GLP1RA drug class are rapidly becoming the most effective treatment for both diabetes and overweight/obesity. By controlling diabetes and overweight/obesity, we hypothesized that the GLP1RAs might be effective at reducing incidence of colorectal cancer.

Response: Parkinson’s disease (PD) is the second most common age-related neurodegenerative disorder. It is characterized by the accumulation of pathologically misfolded α-synuclein (αSynP) aggregates in the brain. Currently, a definite diagnosis relies on the detection of αSynP-containing Lewy bodies in the brain of PD patients. Development of a reliable and sensitive assay for αSynP in easily accessible peripheral tissue specimens is critical for early or differential diagnosis, determination of disease severity, and evaluation of therapeutic efficacy in clinical trials. Previous studies have revealed that the pathologically phosphorylated α-synuclein is detectable with traditional immunohistochemistry (IHC) and immunofluorescence (IF) microscopy but the sensitivity with IHC/IF is highly variable and inconsistent. Also the prion-like aggregation seeding activity of αSynP is detected in cerebrospinal fluid (CSF) of Parkinson’s disease patients with highly sensitive real-time quaking-induced conversion (RT-QuIC) and protein misfolding cyclic amplification assays (PMCA). But the lumbar puncture to collect CSF is more invasive compared to skin punch biopsy.

Ghannoum, PhDDirector of the Center for Medical MycologyCase Western Reserve School of Medicine and UH Dr. Ghannoum[/caption] Professor Mahmoud A. Ghannoum, PhD Director of the Center for Medical Mycology Case Western Reserve School of Medicine and UH MedicalResearch.com: What are the main findings?  Response: The driving force for this study was our finding that patients with Crohn’s disease had a significantly high level (or abundance) of pathogenic fungi (called Candida tropicalis) as well as bacteria (Escherichia coli, and Serratia Marcescens) compared to their non-diseased first-degree relatives. Not only were their levels high, but these organisms cooperated to form polymicrobial digestive plaque (or digestive biofilms) that aggravated the inflammatory symptoms in these patients. Based on this we wanted to develop a probiotic that targeted these organisms and the biofilms they form. Our efforts led to the design of the novel Biohm probiotic which we tested and the results were described in our publication.

Would you briefly explain the significance of prion-induced diseases and why they have been difficult to diagnosis? Response: Our previous study has demonstrated that infectious prions are detectable in the skin samples of patients with sporadic Creutzfeldt-Jakob disease (sCJD), the most common form of human prion disease, at the terminal stage by the highly sensitive real-time quaking-induced conversion (RT-QuIC) assay and animal-based bioassay. The prion-induced diseases are significant because they are infectious diseases that can be transmitted inter-species and intra-species. For instance, mad cow disease, a prion disease in cattle, has been documented to transmit to humans. Currently, there are no cures for these fatal diseases. The definite diagnosis of prion diseases is difficult because it mainly depends on the availability of brain tissues obtained either by biopsy or autopsy for detection of prions. Brain biopsy is highly invasive and it is difficult to be accepted by patients and their families. Even for brain autopsy, it is not always feasible because of religious and cultural limitations in some regions or countries.

MedicalResearch.com Interview with: [caption id="attachment_44810" align="alignleft" width="200"]Raghav Tripathi, MPH Case Western Reserve University MD Candidate, Class of 2021 Raghav Tripathi[/caption] Raghav Tripathi, MPH Case Western Reserve University MD Candidate, Class of 2021 MedicalResearch.com: Why did you decide to perform this study? Response: Differences in the impact of dermatologic conditions on different groups have been of interest to our research group for a long time. Previously, our group had found differences in time to treatment for patients with different skin cancers. Beyond this, we had found differences in mortality and incidence of various skin conditions (controlling for other factors) in different racial groups/ethnicities, socioeconomic groups, demographic groups, and across the rural-urban continuum. The goal of this study was to investigate socioeconomic and demographic differences in utilization of outpatient dermatologic care across the United States. As demographics throughout the country become more diverse, understanding differences in utilization of dermatologic care is integral to developing policy approaches to increasing access to care across the country.
