Ethnic differences may substantially influence the morphological characteristics of the ascending aorta, with potential implications for clinical assessment and management of aortic dilatation. This systematic review evaluated the impact of ethnicity on ascending aorta diameter and dilatation rates, highlighting the need for more tailored, ethnicity-specific care in cardiovascular practice. We identified 11 studies that measured ascending aorta dimensions using transthoracic echocardiography (TTE), computed tomography (CT), or magnetic resonance imaging (MRI). Most investigations focused on Asian, Caucasian, African American, and Hispanic populations. Data extraction revealed notable variability in baseline aortic diameters across ethnic groups. Some studies found no significant differences between …

A Retrospective Analysis Of The Effects Of Pneumonia And Chronic Obstructive Pulmonary Disease On Patient Mortality In Southwest Missouri, Cameron Smith, Monika Ziogaite, Lindsay Doolan-Mattice, Heather Vonhegel, Mariam Akhtar, Nova Beyersdorfer, Kerry Johnson, John Paulson

Student Publications

Chronic obstructive pulmonary disease (COPD) is a progressive lung disease. In this study, we aimed to explore the effects of COPD and pneumonia on the mortality rates among patients admitted to the Freeman Health System in Southwest Missouri, to provide a better idea of whether there is a correlation between the two and whether the presence of both adds to the mortality rates. Patient data were extracted from electronic medical records, focusing on patients with or without COPD and pneumonia diagnoses. Analyses revealed a statistical difference, with a p-value of <0.0001, in mortality rates between COPD patients with (P1) and without (P3) pneumonia, indicating that pneumonia did have an impact on COPD patients. However, pneumonia patients without COPD (P2) had a higher, but non-statistical difference in mortality rates compared to COPD patients with pneumonia (P1), with a p-value of 0.0806. These findings emphasize the severe influence of pneumonia in both COPD and non-COPD populations in the area, warranting further investigation and emphasizing the importance of timely and appropriate treatment. These results provide insights into the interplay between COPD and pneumonia in the geographic area, which may provide guidance in treatment decisions that may improve patient outcomes.


Tourism Carrying Capacity At Petungkriyono Forest And Its Supporting Areas, Nurwidya Ambarwati Dec 2024

Tourism Carrying Capacity At Petungkriyono Forest And Its Supporting Areas, Nurwidya Ambarwati

Journal of Environmental Science and Sustainable Development

Supported by a variety of diversity and landscapes, the development of tourism in the Petungkriyono area is growing rapidly. Optimizing ecotourism services in the Petungkriyono forest without disrupting the ecosystem and damaging the environment can be done by limiting the number of visitors at tourism sites. This study aims to find out information about the tourism capacity of some tourist attractions in the local forest. This study uses the Cifuentes model to predict the maximum number of visitor capacities that can be accommodated in a tourist attraction called Physical Carrying Capacity (PCC), Real Carrying Capacity (RCC), and Effective Carrying Capacity …

Journal of Environmental Science and Sustainable Development

Municipal solid waste (MSW) management presents significant environmental challenges, especially with increasing urbanization and population growth. This study assesses the environmental impacts of MSW, focusing on waste composition, management practices, and their effects on air, water, and soil quality. The primary objective is to evaluate how MSW contributes to environmental degradation and to explore strategies for mitigating these impacts. A hypothesis was developed that optimizing waste composition through proper sorting and treatment can reduce the environmental footprint of MSW management by at least 10% in terms of leachate production and greenhouse gas emissions. Samples were collected using a randomized sampling …

Journal of Environmental Science and Sustainable Development

Halving the number of global deaths and injuries from road traffic accidents is one target of the Sustainable Development Goals 2030, which is still a challenging problem in Indonesia. However, the majority of research on this topic uses accident-based methods, which limits the safety analysis. Two road safety assessment methods are used to close the gap, with the addition of non-accident-based methods such as Road Safety Audits (RSA). The Margonda Raya Road, which is categorised as a traffic accident blackspot, was selected for the case study. For this, a field survey of the road segment is carried out. To minimise …

Optimization Of External Disintegrating Materials In Wet Granulation Formulation Of Ondansetron Tablets, Yandi Permana, Syahrul Tuba, Taufik Riyadi, Sugindro Sugindro

Pharmaceutical Sciences and Research

Inadequate management of chemotherapy-induced side effects, including nausea and vomiting, can impact the healing response of cancer patients. Ondansetron, a preferred medication for the treatment, is classified as a biopharmaceutic classification system (BCS) class II drug, which limits its bioavailability. To enhance its solubility, sodium starch glycolate (SSG) and pregelatinized starch (PG) are used as super disintegrants. This study investigates the impact of these super disintegrants on ondansetron dissolution and identifies the optimal formulation. Ondansetron tablets were prepared using the wet granulation method, with nine formulations varying in SSG and PG concentrations (0%, 1%, 3%, 5%, and 7%). The tablets …

Faculty, Staff and Students Publications

CAR-T cell therapy has established itself as a highly effective treatment for hematological malignancies. There are currently six commercial CAR-T products that have been FDA approved for diseases such as B-ALL, LBCL, MCL, FL, MM, and CLL/SLL. "Real-world" studies allow us to evaluate outcomes from the general population to determine their efficacy and safety compared to those who were included in the original trials. Based on several well conducted "Real-world" studies that represent diverse populations, we report that outcomes from the original trials that led to the approval of these therapies are comparable to those in practice.
