Psychology Faculty Articles and Research

Aims

Optimism is associated with reduced cardiovascular disease risk; however, few prospective studies have considered optimism in relation to hypertension risk specifically. We investigated whether optimism was associated with a lower risk of developing hypertension in U.S. service members, who are more likely to develop high blood pressure early in life. We also evaluated race/ethnicity, sex and age as potential effect modifiers of these associations.

Methods

Participants were 103 486 hypertension-free U.S. Army active-duty soldiers (mean age 28.96 years, 61.76% White, 20.04% Black, 11.01% Hispanic, 4.09% Asian, and 3.10% others). We assessed optimism, sociodemographic characteristics, health conditions, health behaviours and …

Pharmacy Faculty Articles and Research

Tuberculosis (TB) is currently one of the leading causes of global mortality. Medical non-compliance due to the length of the treatment and antibiotic side effects has led to the emergence of multidrug-resistant (MDR) strains of Mycobacterium tuberculosis (M. tb) that are difficult to treat. A current therapeutic strategy attempting to circumvent this issue aims to enhance drug delivery to reduce the duration of the antibiotic regimen or dosage of first-line antibiotics. One such agent that may help is cyclic peptide [R₄W₄], as it has been shown to have antibacterial properties (in combination with tetracycline) …

Decreasing Bias And Improving Education On Non-Invasive Colorectal Screening Methods, Sara H. Hughes

MSN Capstone Projects

It is estimated that in 2020, nearly 148,000 Americans will be diagnosed with colorectal cancer and 53,200 Americans will die from colorectal cancer (Siegel et al., 2020). One- half of all cases and deaths are due to modifiable risk factors such as diet and smoking and it has been shown that early screening and detection can greatly decrease the morbidity and mortality of colorectal cancer yet colorectal cancer related deaths still ranks among the leading causes of cancer-related deaths in the United States and the world. Early detection of colorectal cancer is crucial to reducing mortality and although this is …

Particulate Matter Pollution And Its Effect On Covid-19, Aída Fica Conejeros

International Programs

Growing research supports the significant effects of particulate matter on COVID-19. This air pollutant has been identified before as responsible for serious respiratory diseases. Studies on the differences in high and low polluted cities confirmed that COVID-19 not only correlates to the number of infections but also, increases of 1 ��g/m3 can cause a mortality rate to rise by 8% and the hospital admissions by 4.4%. However, laboratory studies are still needed to support these findings.

Stress And Negative Affect As Mediators In The Association Between Parental Social Support And Lung Function In Adolescents With Asthma, Amber Osorno, Eric Sternlicht, Pornchai Tirakitsoontorn, Azucena Talamantes, Anchalee Yuengsrigul, Zeev N. Kain, Brooke Jenkins

SURF Posters and Papers

Asthma is the leading chronic condition amongst children in the United States as 7.5% of children are diagnosed with asthma. Studies have shown that positive social support is associated with positive asthma management. A strong social support system predicts good management of asthma symptoms; however, current literature has not yet examined how social support impacts lung function as opposed to merely symptom management. Stress and negative affect have been revealed to be associated with worse asthma control, as well as exacerbation of symptoms. Stressful situations, such as the death of a family member, unemployment, and familial tensions lead to worsening …

Cytokine Storm In Covid-19: An Overview, Mechanism, Treatment Strategies, And Stem Cell Therapy Perspective, Nuriza Ulul Azmi, Meidi Utami Puteri, Donny Lukmanto

Pharmaceutical Sciences and Research

Coronavirus disease 2019 (COVID-19) is the disease caused by the highly transmittable novel coronavirus (SARS-CoV-2) infections. The disease was found at the end of December 2019, in Wuhan, China, and quickly spread worldwide with a higher mortality rate compared to the previous coronavirus disease. Cytokine plays an important role in the inflammatory response against coronavirus infection. However, in severely ill patients with COVID-19, an excessive amount of cytokine serum level (cytokine storm) has been associated with the aggravation of coronavirus disease leading to acute respiratory distress syndrome (ARDS). Thus, the management of the cytokine storm could be the key to …

Fosl1 Is A Novel Mediator Of Endotoxin/Lipopolysaccharide-Induced Pulmonary Angiogenic Signaling., Christopher R. Nitkin, Sheng Xia, Heather Menden, Wei Yu, Min Xiong, Daniel P. Heruth, Shui Qing Ye, Venkatesh Sampath

Manuscripts, Articles, Book Chapters and Other Papers

Systemic sepsis is a known risk factor for bronchopulmonary dysplasia (BPD) in premature infants, a disease characterized by dysregulated angiogenesis and impaired vascular and alveolar development. We have previoulsy reported that systemic endotoxin dysregulates pulmonary angiogenesis resulting in alveolar simplification mimicking BPD in neonatal mice, but the underlying mechanisms remain unclear. We undertook an unbiased discovery approach to identify novel signaling pathways programming sepsis-induced deviant lung angiogenesis. Pulmonary endothelial cells (EC) were isolated for RNA-Seq from newborn C57BL/6 mice treated with intraperitoneal lipopolysaccharide (LPS) to mimic systemic sepsis. LPS significantly differentially-regulated 269 genes after 6 h, and 1,934 genes after …

Sepsis Pathophysiology, Samantha Kingsley

Nursing Student Class Projects (Formerly MSN)

Sepsis is one of the most common diagnoses in medical intensive care units (MICUs) worldwide. Sepsis is a medical emergency where prompt intervention is vital to promoting positive patient outcomes. Septic shock develops when sepsis has progressed to the point of persistent hypotension despite appropriate fluid resuscitation. It is important to recognize the early signs of sepsis and intervene to prevent further progression. As the understanding of the pathophysiology has developed further over the years, the treatments and outcomes associated with sepsis have also improved. However, prompt recognition and intervention have always been at the forefront of management and should …

Effect Of S100b Deletion On Membrane Properties And Localization Of Ncald And Hpca, Natasha Hesketh

Graduate School of Biomedical Sciences Theses and Dissertations

Calcium signaling is particularly important for neuronal function. Neurons utilize a wide range of calcium-binding proteins. Dysregulation of such proteins is linked to neurodegeneration. Neurocalcin delta (NCALD), hippocalcin (HPCA), and S100B are calcium sensors that are expressed in the hippocampus, a brain region essential to memory and severely damaged in Alzheimer’s disease (AD). Despite the potential importance of these proteins, we do not fully understand the physiological significance of their relationship. Because NCALD and HPCA are known to interact with S100B, we hypothesized that the loss of S100B affects NCALD and HPCA localization, and therefore electrical properties, of hippocampal neurons. …

Interventricular Septal Rupture In A 62-Year-Old Man With Familial Amyloid Polyneuropathy, Stefano Pidello, Erika Simonato, Fulvio Orzan, Simone Frea, Antonella Barreca, Mauro Rinaldi, Massimo Boffini

The Texas Heart Institute Journal

Cardiac involvement in familial amyloid polyneuropathy consists of arrhythmias, conduction disturbances, and heart failure. To our knowledge, heart rupture has never been described in association with this condition. We report the case of a 62-year-old man with a 6-year history of refractory familial amyloid polyneuropathy who underwent liver transplantation. The operation was complicated by severe hypotension because the neuropathy involved the autonomic system. Perioperatively, the patient had a myocardial infarction, and during the next 10 days, a complete interventricular septal rupture developed, resulting in a systemic-to-pulmonary shunt. Coronary angiographic findings were normal. However, the shunt caused unstable hemodynamics, resulting in …
