Air Pollution And Diseases: Signaling, G Protein-Coupled And Toll Like Receptors, Isabella Cattani-Cavalieri, Katrina F. Ostrom, Jordyn Margolis, Rennolds S. Ostrom, Martina Schmidt

Pharmacy Faculty Articles and Research

Air pollution is a significant public health issue that impacts lung health, particularly in vulnerable populations such as children, the elderly, and individuals with pre-existing respiratory conditions. Both natural and anthropogenic sources of air pollution give rise to a variety of toxic compounds, including particulate matter (PM), ozone (O₃), sulfur dioxide (SO₂), nitrogen dioxide (NO₂), carbon monoxide (CO), and polycyclic aromatic hydrocarbons (PAHs). Exposure to these pollutants is strongly associated with the development and exacerbation of respiratory diseases, including asthma, chronic obstructive pulmonary disease (COPD), lung cancer, and idiopathic pulmonary fibrosis (IPF). Notably, early life exposure to pollutants such as …

Enhancing Cataract Surgery Outcomes: Optimal Use Of Pre- And Post-Operative Eye Drops, Keith Skolnick M.D., Anu Valiaveedu

Mako: NSU Undergraduate Student Journal

Many preoperative and postoperative cataract patients struggle with comprehending the use of prescription medication as directed. Language barriers and low health literacy levels are major factors contributing to improper use of prescriptions. To increase patients comprehension, the Fort Lauderdale Eye Institute employed an educational intervention consisting of a live presentation and an instructional video. Results found that 44% of patients were hesitant to ask questions to clinical staff, 32% felt overwhelmed, and nearly 70% lacked confidence in using their prescribed eye drops. Following the intervention, 91% of patients reported increased confidence in their medications, and most indicated that the video …

Haaning, Brian J. Sandri, Henry L. Wyneken, William T. Goldsmith, Joshua P. Nixon, Timothy R. Nurkiewicz, Chris H. Wendt, Paul Barach, Janeen H. Trembley, Tammy A. Butterick

College of Population Health Faculty Papers

Military personnel deployed to Iraq and Afghanistan were exposed to emissions from open-air burn pits, where plastics, metals, and medical waste were incinerated. These exposures have been linked to deployment-related respiratory diseases (DRRD) and may also impact neurological health via the lung-brain axis. To investigate molecular mechanisms, adult male rats were exposed to filtered air, naphthalene (a representative volatile organic compound), or a combination of naphthalene and carbon black (surrogate for particulate matter; CBN) via whole-body inhalation (six hours/day, three consecutive days). Lung, brain, and plasma samples were collected 24 h after the final exposure. Pro-inflammatory biomarkers were assessed using …

Review Of The Diagnosis, Pathophysiology, And Treatment Of Naegleria Fowleri-Induced Primary Amoebic Meningoencephalitis, Terrance Zhang

MCB Articles

Naegleria fowleri is a thermophilic, ubiquitous, free-living amoeba, but is also known as the “brain-eating” amoeba. This is the etiological agent of a rare and fulminant waterborne disease known as Primary Amoebic Meningoencephalitis (PAM) that is acutely fatal in 90-99% of reported cases. Those who come into contact with infested waters are at risk of introducing the amoeba into their upper nasal canal, whence the trophozoite form is known to migrate along the olfactory nerve, through the cribriform plate, and enter the central nervous system. Although the exact pathogenesis of N. fowleri is not known, studies have demonstrated contact-dependent and …

Soluble Antimicrobial Peptide (Amp) Screening To Rationally Design Amp-Hydrogels That Selectively Prevent Biofilm Formation, Matthias Recktenwald, Muskanjot Kaur, Mohammed M. Benmassaoud, Aryanna Copling, Tulika Khanna, Michael Curry, Denise Cortes, Gilbert Fleischer, Valerie J. Carabetta, Sebastián L. Vega

Rowan-Virtua Research Day

Staphylococcus aureus is an opportunistic pathogen that lives on surfaces and skin and can cause serious infections once inside the body. While antibiotics effectively kill bacteria, there are a growing number of infections with antibiotic-resistant strains. Antimicrobial peptides (AMPs) are part of the innate immune system and can eliminate pathogens including bacteria, fungi, and viruses, and are a promising alternative to antibiotics. Although studies have reported that AMP-functionalized hydrogels can prevent bacterial adhesion and biofilm formation, these materials generally consist of one AMP at an arbitrary concentration, and AMP dosing and the combined effects of multiple AMPs are not well …

Environmental Exposures And Aging., Daniel Chris Gomes

Electronic Theses and Dissertations

In recent years, research into air pollution has shown that exposure to certain components in air pollution, primarily PM2.5 can accelerate biological aging and thereby lead to increased susceptibility to multiple diseases. We hypothesize that prolonged exposure to air pollutants can result in premature aging leading to extensive tissue dysfunction and susceptibility to diseases. To examine this, we exposed mice to PM2.5 for 9, 15, and 21 days, then measured the telomere lengths, cellular senescence, and histone methylation patterns of multiple cell types. We found consistently increased telomere attrition, cellular senescence and advanced age-consistent histone methylation patterns in groups exposed …

Journal of Patient-Centered Research and Reviews

Anecdotally, there are attestations from clinicians of calcium carbonate being used successfully for laboring people experiencing labor dystocia. The goal of this narrative review was to provide a synopsis of pertinent literature on calcium use in obstetrics to explore the potential benefit of calcium carbonate as a simple and low-cost intervention for prevention or treatment of labor dystocia. To answer how calcium and carbonate physiologically contribute to myometrium contractility, we conducted a literature search of English-language peer-reviewed articles, with no year limitation, consisting of the keywords “calcium,” “calcium carbonate,” “calcium gluconate,” “pregnancy,” “hemorrhage,” and variations of “smooth muscle contractility” and …

Detection Of Sars-Cov-2 Mutations In Vermillion, Sd, Wastewater Utilizing Probe-Based Rt-Qpcr, Matthew J. Schmitz

Honors Thesis

The COVID-19 pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from the subgenus Sarbecovirus, has presented numerous public health challenges for communities across the globe. As demonstrated by the Delta variant (B.1.617.2) and the recent Omicron variants, the virus can mutate and pose new risks for communities, such as reinfection, increased transmissibility, and variable mortality. As such, accurately monitoring the spread of specific variants has become a priority for public health agencies. However, clinical testing faces various limitations, and the increased use of at-home test kits inhibits surveillance. Wastewater-based epidemiology (WBE) can monitor infection rates of entire …

Early Detection Of Atypical Motor And Neurobehavior Of Infants At Risk Secondary To Opioid Exposure: A Prospective Study, Kara Boynewicz

Electronic Theses and Dissertations

Prenatal opioid exposure has been studied in relation to infants' medical outcomes. However, large gaps exist in the literature supporting early identification of atypical neurobehavior and motor development of infants with prenatal opioid exposure. The purpose of the study was to investigate whether prenatal opioid exposure has a negative influence on a newborn infant’s neurobehavior and motor development to aid in the early identification of potential delays. Using a prospective quasi experimental design, infants motor development using the Test of Infant Motor Performance (TIMP) and neurobehavior using the NICU Neonatal Network Scale (NNNS) was assessed on 58 infants in a …

Contraceptive Methods In The United States: The Question Of Abortive Mechanisms, Tara Ferenczy

Senior Honors Theses

This thesis reviews the many methods of contraception available in the United States. Although society’s understanding of women’s health has become a major topic, there is still a significant deficit of information regarding how the accessible methods affect women’s bodies, specifically reproductive tissue. The thesis analyzes numerous contraceptive options focusing specifically on the mechanisms of action to determine whether options have abortifacient properties so that readers may develop educated opinions regarding medical and ethical uses. Information involving strengths and limitations of each technique and the effects on both the female body and the reproductive material assist in understanding the process …

Oral Contraceptives As Possible Acl Injury Prevention Method, Haley Schweizer

Department of Biological & Biomedical Sciences

Genetic polymorphism of drug metabolizing enzymes and transporters may influence drug response. The frequency varies substantially between ethnicities thus having implications on appropriate selection and dosage of various drugs in different populations. The distribution of genetic polymorphisms in healthy Pakistanis has so far not been described. In this study, 155 healthy adults (98 females) were included from all districts of Karachi. DNA was extracted from saliva and genotyped for relevant SNVs in CYP1A1, CYP2B6, CYP2C9, CYP2C19, CYP2D6, CYP3A4 and CYP3A5 as well as ALDH3A1, GSTA1, ABCB1 and ABCC2. About 64% of the participants were born to parents who were unrelated …

Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender

Student Theses 2015-Present

This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim …

Abnormal Dendritic Maturation Of Developing Cortical Neurons Exposed To Corticotropin Releasing Hormone (Crh): Insights Into Effects Of Prenatal Adversity?, Megan M. Curran, Curt A. Sandman, Elyssia Poggi Davis, Laura M. Glynn, Tallie Z. Baram

Psychology Faculty Articles and Research

Corticotropin releasing hormone (CRH) produced by the hypothalamus initiates the hypothalamic- pituitary-adrenal (HPA) axis, which regulates the body's stress response. CRH levels typically are undetectable in human plasma, but during pregnancy the primate placenta synthesizes and releases large amounts of CRH into both maternal and fetal circulations. Notably, placental CRH synthesis increases in response to maternal stress signals. There is evidence that human fetal exposure to high concentrations of placental CRH is associated with behavioral consequences during infancy and into childhood, however the direct effects on of the peptide on the human brain are unknown. In this study, we used …

Antenatal Glucocorticoid Treatment Is Associated With Diurnal Cortisol Regulation In Term-Born Children, M. N. Edelmann, Curt A. Sandman, Laura M. Glynn, D. A. Wing, Elyssia Poggi Davis

Psychology Faculty Articles and Research

Due to the rapid developmental changes that occur during the fetal period, prenatal influences can affect the developing central nervous system with lifelong consequences for physical and mental health. Glucocorticoids are one of the proposed mechanisms by which fetal programing occurs. Glucocorticoids pass through the blood-brain barrier and target receptors throughout the central nervous system. Unlike endogenous glucocorticoids, synthetic glucocorticoids readily pass through the placental barrier to reach the developing fetus. The synthetic glucocorticoid, betamethasone, is routinely given prenatally to mothers at risk for preterm delivery. Over 25% of the fetuses exposed to betamethasone will be born at term. Few …

The Morbidity & Mortality Of Prevalent Heart Failure, Jennifer Kwon

Loma Linda University Electronic Theses, Dissertations & Projects

The first study population included 292 unselected consecutive patients from the LLUMC heart failure clinic who were enrolled in the study from January to July 2006 and were followed up through the end of December 2010. The treatment policy at the clinic was to uptitrate dosages of beta-adrenergic blockade (β-blockers), angiotensin-converting-enzyme inhibitors (ACEi) and angiotensin II receptor blockers (ARB) to the most tolerable levels in order to reach target dosages, as recommended by the Heart Failure Society of America (HFSA). Patients were classified into systolic heart failure (ejection fraction (EF) < 40%) or diastolic heart failure (EF≥40%). All dosages of β-blockers, ACEi and ARB were extracted through chart reviews and were used as the main predictors of the patients' survival. Results from analyses showed that reaching target dosages of β-blockers and ACEi/ARB may increase survival when compared to not reaching target among the systolic HF population (HR_{β_biockers}= 0.64, 95% CI 0.26-1.56 and HR_ACEi/ARB=0.50, …

Relationship Of Vitamin D Levels To Blood Pressure In A Biethnic Cohort, Rosario O. Sakamoto

Loma Linda University Electronic Theses, Dissertations & Projects

Background: Serum hydroxyvitamin D [25(OH)D] has been well-accepted as not an ordinary vitamin but a pro-hormone that has many benefits beyond its well-known effects on bone. Cardiovascular risk factors such as hypertension remain a huge health burden and Blacks have been recognized to have higher prevalence of hypertension compared to non-Hispanic Whites. Despite increasing evidence of the benefits of vitamin D on blood pressure control, there is much more to be learned about the relationship of serum 25(OH)D to blood pressure among different ethnicities.

Purpose: The goal of this study was to determine whether vitamin D serum 25(OH)D levels were …

What Is The Risk Of Teratogenicity With The Use Of Selective Serotonin Reuptake Inhibitors During Pregnancy?, Michael Z. Wincor, Mary Gutierrez, Ann Nguyen

Pharmacy Faculty Articles and Research

"The lifetime prevalence of major depressive disorder in women is 10 to 25%, with an average age of onset in the mid-20s.1 Over the nine years that the selective serotonin reuptake inhibitors (SSRis) have been available, for many prescribers, they have become first-line agents in the treatment of depression. In addition, sorne of them are also being used in the treatment of obsessive- compulsive disorder and panic disorder. In light of these facts, itis not unlikely that women of childbearing age would be treated with one of the SSRis. In considering the risks of exposing a fetus to an SSRI, …
