Faculty, Staff and Student Publications

The coming of age for cancer treatment has experienced exponential growth in the last decade with the addition of immunotherapy as the fourth pillar to the fundamentals of cancer treatment-chemotherapy, surgery, and radiation-taking oncology to an astounding new frontier. In this time, rapid developments in computational biology coupled with immunology have led to the exploration of priming the host immune system through vaccination to prevent and treat certain subsets of cancer such as melanoma and hereditary colorectal cancer. By targeting the immune system through tumor-specific antigens-namely, neoantigens (neoAgs)-the future of cancer prevention may lie within arm's reach by employing neoAg …

Journal of Mind and Medical Sciences

Situs inversus totalis (SIT) is a rare congenital disease that causes mirror transposition of the abdomino-thoracic structures. When such patients develop pathologies related to the bile duct, most commonly choledocholithiasis, the optimal diagnostic process can be hampered by the rarity of such a pathology and the lack of medical information on this topic. Once the diagnosis is established, through endoscopic ultrasound and MRCP, the patient is sent to perform ERCP, which requires tailored approaches for each case. We present the case of a 33-year-old patient who was previously documented with SIT. On admission she presented with abdominal pain and fever …

Genetic And Serological Markers In Colorectal Cancer Surgery, Adrian Silaghi, Vlad Denis Constantin, Dragos Serban, Dragos Epistatu, Ioana Paunica, Daniela Gabriela Bălan, Laura Florentina Rebegea

Journal of Mind and Medical Sciences

Colon cancer is relatively asymptomatic in the early stages, the manifestations appearing and intensifying with the evolution of the disease, especially when associated with local and/or systemic complications. In such cases, surgical interventions are often emergency and involve more extensive operations (on metabolically and immune-stressed organisms), so that an early diagnosis (endoscopy, tumor markers, etc.) remains not only desirable but even a priority, especially in predisposed patients (genetic factors, lifestyle, etc.). As a consequence, the involvement of tumor markers in colon neoplasms has become more and more investigated in recent times. This review investigates the roles of serological and genetic …

Journal of Mind and Medical Sciences

Despite continuous investigations in the diagnosis and treatment of severe acute pancreatitis (SAP), this disease still remains a critical condition with a mortality rate of up to 35%. The pathophysiology of SAP involves an important inflammatory reaction of the pancreas (mediated by inflammatory cytokines and immune system activation), causing severe local tissue damage as well as important systemic imbalances. IL-17 is an inflammatory mediator that have a pivotal role in SAP evolution, generating multiple interactions between inflammatory cytokines and significantly influencing the immune system response. Consequently, continuous renal replacement therapy/CRRT was added to the conventional therapy, leading to improved treatment …

HCA Healthcare Journal of Medicine

Introduction

Thiamine deficiency, also known as beriberi, is a nutritional disorder caused by a lack of thiamine (vitamin B₁) in the diet. It can occur in 2 forms: dry beriberi, which affects the nervous system, and wet beriberi, which affects the cardiovascular system. Gastrointestinal beriberi is a subtype that affects the digestive system and can lead to multisystem involvement. In the United States (US), thiamine deficiency often arises from chronic malnutrition secondary to alcoholism, known as Wernicke-Korsakoff Syndrome.

The gut microbiota has been found to play an important role in the progression of metabolic dysfunction-associated steatohepatitis (MASH), but the mechanisms have not been established. Here, by developing a click-chemistry-based enrichment strategy, we identified several microbial-derived bile acids, including the previously uncharacterized 3-succinylated cholic acid (3-sucCA), which is negatively correlated with liver damage in patients with liver-tissue-biopsy-proven metabolic dysfunction-associated fatty liver disease (MAFLD). By screening human bacterial isolates, we identified Bacteroides uniformis strains as effective producers of 3-sucCA both in vitro and in vivo. By activity-based protein purification and identification, we identified an enzyme annotated as β-lactamase in B. …
