SMU Data Science Review

Irritable Bowel Disease (IBD) affects a sizable portion of the US population, causing symptoms such as vomiting, abdominal pain, and diarrhea. Despite the disease’s prevalence, the precise cause is not fully understood. This study consists of endoscopic and histological data from patients diagnosed with IBD and a control population for reference. The machine learning models' focus is to classify patients into IBD types. Several models were analyzed, including decision trees, logistic regression, and k-nearest neighbors. In addition, various methods of SMOTE were applied to determine the most effective transformation and ensuring that the dataset is balanced. The best model with …

Esophageal Atresia Associating Gastrointestinal Malformations: A Study Of Clinical Approach, Dan Alexandru Iozsa, Andreea Cristina Costea, Nicolae Sebastian Ionescu Oct 2021

Esophageal Atresia Associating Gastrointestinal Malformations: A Study Of Clinical Approach, Dan Alexandru Iozsa, Andreea Cristina Costea, Nicolae Sebastian Ionescu

Journal of Mind and Medical Sciences

Digestive tract malformations requiring surgical repair in association with esophageal atresia are rare occurrences. Because of this uncommon presentation of esophageal atresia, its evaluation and management are often difficult, requiring extensive workup and multiple surgical procedures. We present our experience with esophageal atresia associating gastrointestinal congenital anomalies in the last 10 years. Clinical and surgical perspectives were pointed willing to make relevant observations in matters of diagnosis and treatment strategy in these patients. Therefore, 7 cases resembling this pattern were identified – duodenal atresia and anorectal malformation being the most common coexistent malformations. All the cases exhibited technical and procedural …

Journal of Mind and Medical Sciences

We aimed at assessing the interaction between visceral adipose tissue (VAT), insulin resistance (IR), circulating levels of monocyte chemoattractant protein-1 (MCP-1) and malondialdehyde (MDA) and the thyroid parameters in obese subjects. Methods. Obese subjects without thyroid pathologies or diseases associated with systemic inflammation and OS were recruited. Insulinemia, visceral fat thickness, metabolic and thyroid parameters were assayed. Circulating levels of MCP-1 and MDA were used to quantify inflammation and OS. Results. A number of 160 obese subjects were included. The MCP-1 level increased with the degree of obesity and HOMA-IR. MCP 1 was positively associated with antithyroperoxidase antibody (TPOab) levels …

Non-Dental Oral Cavity Findings In Gastroesophageal Reflux Disease: A Systematic Review And Meta-Analysis, Madalina-Gabriela Indre, Darius Sampelean, Vlad Taru, Angela Cozma, Dorel Sampelean, Mircea Vasile Milaciu, Olga Hilda Orasan Apr 2021

Non-Dental Oral Cavity Findings In Gastroesophageal Reflux Disease: A Systematic Review And Meta-Analysis, Madalina-Gabriela Indre, Darius Sampelean, Vlad Taru, Angela Cozma, Dorel Sampelean, Mircea Vasile Milaciu, Olga Hilda Orasan

Journal of Mind and Medical Sciences

Gastroesophageal reflux disease (GERD) is known as the most prevalent gastrointestinal disorder in the United States, leading to substantial morbidity, although associated mortality is rare. Based on the appearance of esophageal mucosa on upper endoscopy, GERD is divided into erosive esophagitis (ERD) and nonerosive reflux disease (NERD). Heartburn and acid regurgitation are the typical symptoms of the disease, although some patients may present atypical manifestations such as epigastric pain, nausea, asthma, chronic cough, pharyngitis, laryngitis, sleep disturbances, otitis, and sinusitis. Other signs, such as oral mucosal lesions may result from GERD by direct acid or acidic vapor contact in the …

Linking The Brain And Bone Through Fat, Elisabeta Malinici, Anca Sirbu, Miruna Popa, Simona Fica Apr 2021

Linking The Brain And Bone Through Fat, Elisabeta Malinici, Anca Sirbu, Miruna Popa, Simona Fica

Journal of Mind and Medical Sciences

Over the past years, bone and adipose tissue have gained interest from researchers in the light of their secretory profiles, being able to produce active molecules, with the final effect of regulating energy homeostasis. Both adipocytes and osteoblasts originate in the pluripotent mesenchymal stem cell and this common origin has been proposed as the core of the fat-bone relationship. The central nervous system might be the third player in this association, capable of integrating signals. Numerous adipose tissue secreted factors that influence energy homeostasis and bone have been described: leptin, adiponectin, lipocalin 2, and inflammatory cytokines (e.g. IL-1, IL-6 and …

Alcohol Consumption And Cognitive Aging: Can It Be Beneficial?, Margarita Velikova, Bistra Galunska, Raya Dimitrova, Zlatislav Stoyanov Apr 2021

Alcohol Consumption And Cognitive Aging: Can It Be Beneficial?, Margarita Velikova, Bistra Galunska, Raya Dimitrova, Zlatislav Stoyanov

Journal of Mind and Medical Sciences

We present a literature review which summarizes the data supporting one of the alternative perspectives on the effect of alcohol consumption on cognitive aging – the possible positive effect of low to moderate drinking. Some of the main theories about aging, the mechanisms of brain aging, and the pathogenesis of cognitive decline and dementia are briefly described. In this context, the putative mechanisms of the protective action of non-alcoholic components in alcoholic beverages or low doses of ethanol against oxidative stress, inflammation, mitochondrial dysfunction, brain insulin resistance, and production of amyloid-β peptides are presented. The review article does not favor …

Growth In A Biofilm Sensitizes Cutibacterium Acnes To Nanosecond Pulsed Electric Fields, Asia Poudel, Adenrele Oludiran, Esin B. Sözer, Maura Casciola, Erin B. Purcell, Claudia Muratori

Bioelectrics Publications

The Gram-positive anaerobic bacterium Cutibacterium acnes (C. acnes) is a commensal of the human skin, but also an opportunistic pathogen that contributes to the pathophysiology of the skin disease acne vulgaris. C. acnes can form biofilms; cells in biofilms are more resilient to antimicrobial stresses. Acne therapeutic options such as topical or systemic antimicrobial treatments often show incomplete responses. In this study we measured the efficacy of nanosecond pulsed electric fields (nsPEF), a new promising cell and tissue ablation technology, to inactivate C. acnes. Our results show that all tested nsPEF doses (250 to 2000 pulses, 280 ns pulses, …

Novel Mechanisms Of Neuronal And Hormonal Regulation Of Large Intestinal Electrolyte Transport, Andrew John Nickerson Jan 2021

Novel Mechanisms Of Neuronal And Hormonal Regulation Of Large Intestinal Electrolyte Transport, Andrew John Nickerson

Graduate Theses, Dissertations, and Problem Reports

The mammalian colon plays a vital role in maintaining overall electrolyte and fluid homeostasis in the body, and it possesses the ability to either secrete or absorb water depending upon the needs of the organism. Secretion or absorption of electrolyte ions, such as Na+, Cl- and K+, drives the movement of water across the colonic epithelium – the inner gut lining where all transport takes place. Aberrant absorptive and/or secretory activity within the colonic epithelium is central to the pathogenesis of many gastrointestinal diseases, such as irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), constipation …
