Menopause is characterized by the cessation of menstruation for 12 consecutive months. In this narrative review, we describe the transitional stages of menopause, clinical presentation, pharmacological management of symptoms, and effects on fluctuating hormone levels. To standardize the stages of menopause, the Stages of Reproductive Aging Workshop + 10 (STRAW+10) system was designed with five distinct categories corresponding to symptom presentation and numerical years. Common clinical presentations consist of vasomotor hot flashes, mood changes, decreased libido, osteoporosis, and genitourinary changes, all of which are associated with changes in hormone levels. Because hormones play a major role in the mechanism of …

Successful Treatment Of A Chronic Recurrent Expanding Hematoma Of The Thigh, Gianfranco Galantini, Bakhtawar Mushtaq, Jesse Ottaway, Charles Long

Abington Jefferson Health Papers

Chronic expanding hematoma (CEH) is a rare entity that poses diagnostic and therapeutic challenges due to persistent growth, risk of recurrence, and potential for blood loss anemia. The most common etiologies of CEH are trauma or surgery. It is thought to occur due to irritant effects of blood breakdown products, causing bleeding from capillaries in chronic granulation tissue. Although treatment of CEH is variable, complete surgical excision of the hematoma and its pseudocapsule is the gold standard. We present a case of a 15-year CEH that was initially treated with limited evacuation of the hematoma and cavity decortication, resulting in …

Remimazolam And Its Place In The Current Landscape Of Procedural Sedation And General Anesthesia, Matthew Brohan, Janette Brohan, Basavana Goudra

Department of Anesthesiology Faculty Papers

Remimazolam was derived from its parent compound by adding an ester linkage into its structure so that the drug becomes a substrate for ester metabolism. As a result, it undergoes organ-independent ester hydrolysis, although the clinical benefits in terms of shorter recovery are not uniformly observed in clinical practice. Remimazolam is mainly tested in procedural sedation. In comparison to propofol, the current gold standard for procedural sedation, its proposed attractiveness is shorter wake-up times and a clear-headed recovery. Its clear advantages over propofol are better hemodynamic stability, lack of pain on injection and availability of a reversal agent in the …

The Potential Anti-Arrhythmic Effect Of Sglt2 Inhibitors, Hong-Yi Duan, Hector Barajas-Martinez, Charles Antzelevitch, Dan Hu

Department of Medicine Faculty Papers

Sodium-glucose cotransporter type 2 inhibitors (SGLT2i) were initially recommended as oral anti-diabetic drugs to treat type 2 diabetes (T2D), by inhibiting SGLT2 in proximal tubule and reduce renal reabsorption of sodium and glucose. While many clinical trials demonstrated the tremendous potential of SGLT2i for cardiovascular diseases. 2022 AHA/ACC/HFSA guideline first emphasized that SGLT2i were the only drug class that can cover the entire management of heart failure (HF) from prevention to treatment. Subsequently, the antiarrhythmic properties of SGLT2i have also attracted attention. Although there are currently no prospective studies specifically on the anti-arrhythmic effects of SGLT2i. We provide clues from …

ONU Student Research Colloquium

ABSTRACT. Caffeine, a widely consumed drug, has been shown to significantly increase heart rate (HR) and blood pressure (Geethavani et al., 2014), but had only insignificant changes in these cardiovascular measurements (Alhabeeb et al., 2022); while Matsumara and his colleagues (2023) reported that caffeine decreased 100-meter sprint times indicating that caffeine may improve anaerobic performance. The current study investigated the short-term effects of caffeine on heart rate (HR, beats per minute), blood pressure (mmHg), and 20-yard sprint performance time (seconds; Dashr Sprint Timing System). These parameters were measured in triplicate before and at 45-minutes after caffeine supplementation at a dose …

The Fight For Fluoridation In Stl, Noor Yousaf

Undergraduate Research Symposium

Fluoridation is the addition of fluoride to a source of drinking water. In St. Louis’s public water supply, the amount of fluoride remains the same since 1953 at 5ppm. Dr. Ralph Rosen and his team of dentists and researchers advocated for the fluoridation of the water because it reduced the frequency of dental caries occurring in children and adults alike, but the public had opinions on the sudden addition of chemicals to their water. This includes how the public’s health will be affected, how consumer products would change, and also how effective this addition of fluoride would be. This debate …

The spore-forming intestinal pathogen Clostridioides difficile causes multidrug resistant infection with a high rate of recurrence after treatment. Piscidins 1 (p1) and 3 (p3), cationic host defense peptides with micromolar cytotoxicity against C. difficile, sensitize C. difficile to clinically relevant antibiotics tested at sublethal concentrations. Both peptides bind to Cu²⁺ using an amino terminal copper and nickel binding motif. Here, we investigate the two peptides in the apo and holo states as antibiotic adjuvants against an epidemic strain of C. difficile. We find that the presence of the peptides leads to lower doses of …

The Kinetic Modulation Of Α - Synuclein Fibrillation And Toxicity By 4-Phenylbutyric Acid, Kristos Awuah Baffour

Graduate Theses/Dissertations

ABSTRACT

The Protein misfolding and aggregation of alpha-synuclein (α-syn) into neurotoxic amyloids underlies the pathogenesis of neurodegenerative diseases such as Parkinson's disease (PD). 4-Phenylbutyrate (PBA), an FDA drug approved for treating urea cycle disorders, has garnered significant attention as a potential chemical chaperone for targeting alpha-synuclein (α-syn) aggregation. Using in vitro assays, we demonstrated that PBA treatment alters the pattern of α-syn aggregation, as evidenced by reduced formation of oligomeric species and its increased susceptibility to proteolytic cleavage under the influence of PBA. Proteinase K assay, surface plasmon resonance, and Nile red studies indicate that PBA interacts with the extensive …

Spiral Wave Teleportation And Multiplex Network Synchronization In Light Sensitive Belousov-Zhabotinsky Systems, Shannyn Alicia Tyler

Graduate Theses, Dissertations, and Problem Reports (ETD)

We experimentally and computationally investigate dynamical behaviors in excitable and oscillatory media using light sensitive Belousov-Zhabotinsky (BZ) systems. These systems are not in a state of thermodynamic equilibrium, and have been proven to show various interesting phenomena including spatiotemporal patterns, self-organization, and chaos. We utilize the BZ reaction, a nonlinear chemical reaction, known for its relaxation-type oscillations, to explore the dynamics of these systems.

We examine spiral wave teleportation in an excitable media as an effective alternate defibrillation method. Spiral waves have emerged as a key phenomenon associated with the initiation and persistence of cardiac arrhythmias. Using a light sensitive …

Introduction: Whole genome sequencing (WGS) of bacterial isolates can be used to identify antimicrobial resistance (AMR) genes. Previous studies have shown that genotype-based AMR has variable accuracy for predicting carbapenem resistance in carbapenem-resistant Enterobacterales (CRE); however, the majority of these studies used short-read platforms (e.g. Illumina) to generate sequence data. In this study, our objective was to determine whether Oxford Nanopore Technologies (ONT) long-read WGS would improve detection of carbapenem AMR genes with respect to short-read only WGS for nine clinical CRE samples. We measured the minimum inhibitory breakpoint (MIC) using two phenotype assays (MicroScan and ETEST) for six antibiotics, …

Exogenous Exposure To Dihydroxyacetone Mimics High Fructose Induced Oxidative Stress And Mitochondrial Dysfunction, Raj Mehta

Honors Theses

Dihydroxyacetone (DHA) is a three-carbon sugar that is the active ingredient in sunless tanning products and a by-product of electronic cigarette (e-cigarette) combustion. Increased use of sunless tanning products and e-cigarettes has elevated exposures to DHA through inhalation and absorption. Studies have confirmed that DHA is rapidly absorbed into cells and can enter into metabolic pathways following phosphorylation to dihydroxyacetone phosphate (DHAP), a product of fructose metabolism. Recent reports have suggested metabolic imbalance and cellular stress results from DHA exposures. However, the impact of elevated exposure to DHA on human health is currently under-investigated. We propose that exogenous exposures to …

Nicotinamide Riboside And Beta-Hydroxybutyrate Activate Parallel Pathways For C. Elegans Lifespan Extension, Mckenzie Peters

Undergraduate Honors Theses

Supplementation with nicotinamide riboside (NR), a form of vitamin B3 and a precursor of nicotinamide adenine dinucleotide (NAD⁺) extends lifespan in the nematode C. elegans and delays aging-related pathologies in mammals. During aging, levels of NAD⁺ decline causing metabolic dysfunction and oxidative damage. Studies in C. elegans found that when NR was administered during larval development it induced the mitochondrial unfolded protein response (UPR^mt), which is frequently associated with lifespan extension. Both calorie restriction (CR) and ketogenic diets (KD) have been shown to extend lifespan, in part through increasing NAD⁺ and through increasing levels …
