Work Place Impact On Mental Wellbeing Of Frontline Doctors, Vishnupriya Veeraraghavan, Krishnan Srinivasan

Journal of Mind and Medical Sciences

Background. Coronavirus Disease 2019 (COVID-19, also known as 2019-nCoV), a cluster of acute respiratory illness with unknown causes, has occurred in India since January 2020. Over the past several months, the entire world is struggling to cope with and contain the virus spread. Several studies showed that mental health problems could occur in both healthcare workers and SARS survivors during the SARS epidemic. Considering the geographical variation, dense population, multi-strata health care structure, and rising COVID cases in South India, we have a reason to speculate that the burden on the frontline doctors is high and their psychological condition …


Indicators Of Psychological Distress And Body Image Disorders In Female Patients With Breast Cancer, Helena Van Oers, Lourens Schlebusch Sep 2020

Indicators Of Psychological Distress And Body Image Disorders In Female Patients With Breast Cancer, Helena Van Oers, Lourens Schlebusch

Journal of Mind and Medical Sciences

Breast cancer patients are vulnerable to elevated stress related to receiving the diagnosis, unfamiliar and invasive treatment, and coping with the side-effects of treatment, which may find various forms of expression. Another common feature of this patient population is body image dysphoria. Both the disease and treatment lead to impairments in physical appearance and general bodily functioning. This study aimed to explore the differential manifestations of stress and the nature of body image dysphoria within a sample of female breast cancer patients (n=80), compared to female patients with other sites of disease (n=80) in order to examine differences in the …

Intestinal Microbiota – A Possible Contributor To Cardiovascular Diseases?, Roua Iorga, Ovidiu Gabriel Bratu, Nicolae Bacalbasa, Mihnea-Alexandru Gaman, Camelia Cristina Diaconu

Journal of Mind and Medical Sciences

The intestinal microbiota represents an interesting and emergent field of research, with already known implications in metabolic and immunological functions. Recently, there is increasing evidence that specific gut microbial populations are associated with cardiovascular diseases. Numerous completed and ongoing studies aim to evaluate the potential of intestinal microbiota assessment to improve the prevention, diagnosis, and therapeutic arsenal of cardiovascular diseases, considering dysbiosis as a cardiovascular risk factor. There is strong evidence for a correlation between intestinal flora imbalance and metabolic changes secondary to bacterial metabolites. In this minireview, we discuss recent data about the connections between intestinal microbiota and cardiovascular …

Composition And Modification Of The Lung Microbiome In Patients With Idiopathic Pulmonary Fibrosis, Victoria Maria Ruta, Teodora Gabriela Alexescu, Ana Rodica Ungur, Milena Adina Man, Victoria Georgiana Sfirlea, Iulia Olimpia Pfingstgraf, Nicoleta Motoc, Carmen Monica Pop

Journal of Mind and Medical Sciences

Lungs have long been considered sterile, but recent research has shown that a large number of microbiological organisms exist in the lungs of healthy subjects (including bacteria, fungi, and viruses), collectively known as the microbiome. It undergoes changes in patients with respiratory pathology. Studies in idiopathic pulmonary fibrosis show that a large number of bacteria or the abundant presence of potentially pathogenic bacteria can cause disease progression and exacerbation, and can implicitly increase mortality. There seems to be a quantitative balance, a well-established proportion between the components of this microbiome, which is disturbed during a disease and can reach a …

Hepatitis C Virus: Host, Environmental And Viral Factors Promoting Spontaneous Clearance, Sergiu Ioan Micu, Marilena Musat, Andrada Dumitru, Dan Nicolae Paduraru, Anca Rogoveanu, Anca Dumitriu, Stana Paunica, Cristian Balalau, Roxana Emanuela Popoiag

Journal of Mind and Medical Sciences

Hepatitis C virus (HCV) is a pathogenic entity which determines inflammation and liver damage through complex immune mechanisms. Although progress has been made in managing the disease course, chronic infection still remains a significant cause of morbidity and mortality to this day. Because both acute and chronic infection are often asymptomatic, chronic infection is frequently diagnosed when its complications have developed. In a small proportion of cases, the chronic infection does not develop, the immune system managing to cleanse the body from this silent pathogen in the absence of specific treatment, a process called spontaneous viral clearance, which occurs rarely, …


Diagnosis And Management Of Pericardial Effusion, Maria Manea, Ovidiu Gabriel Bratu, Nicolae Bacalbasa, Camelia Cristina Diaconu Sep 2020

Diagnosis And Management Of Pericardial Effusion, Maria Manea, Ovidiu Gabriel Bratu, Nicolae Bacalbasa, Camelia Cristina Diaconu

Journal of Mind and Medical Sciences

Pericardial effusion is a common pathology in clinical practice. The etiology of pericardial effusion is diverse, from infectious diseases, malignancies, autoimmune diseases, chronic renal failure, to drug-related or after an invasive cardiac intervention. Clinical presentation of pericardial effusion is variable, depending on the volume of the fluid and the rate of accumulation. Clinical manifestations are dramatic if the pericardial fluid accumulates rapidly. Classical symptoms in pericardial effusion include pleuritic chest pain associated with dyspnea. In case of cardiac tamponade, orthopnea, jugular venous distension, pulsus paradoxus, hypotension, and shock appear. Transthoracic echocardiography is the gold standard investigation for the diagnosis of …

Oral manifestations are present both in Cushing's syndrome and in adrenal insufficiency. Possible oro-dental pathology in patients with Cushing's syndrome include jawbone loss, tooth loss, and periodontal diseases. Professional societies did not include Cushing's syndrome as being part of systemic diseases associated with loss of periodontal supporting tissues. The comorbidities of Cushing's syndrome such as obesity, osteoporosis, and diabetes are conditions that influence periodontal attachment apparatus. In patients with adrenal primary insufficiency, the most specific sign is the melanic pigmentation of the skin and mucosal surfaces due to increments of corticotropin and pro-opiomelanocortin peptide levels that occur as a result …

Nebraska Center for Virology: Faculty Publications

Potassium ion (K+) channels have been observed in diverse viruses that infect eukaryotic marine and freshwater algae. However, experimental evidence for functional K+ channels among these alga-infecting viruses has thus far been restricted to members of the family Phycodnaviridae, which are large, double-stranded DNA viruses within the phylum Nucleocytoviricota. Recent sequencing projects revealed that alga-infecting members of Mimiviridae, another family within this phylum, may also contain genes encoding K+ channels. Here we examine the structural features and the functional properties of putative K+ channels from four cultivated members of Mimiviridae. While all four proteins contain variations …

Background: A major challenge in implementing personalized medicine in pediatrics is identifying appropriate drug dosages for children. The majority of drug dosing studies have been based on adult populations, often with modification of the dosing for children based on size and weight. However, the growth and development experienced by children between birth and adulthood represents a dynamically changing biological system, with implications for effective drug dosing, efficacy as well as potential drug toxicity. The purpose of this study was to apply a metabolomics approach to gain preliminary insights into the ontogeny of liver function from newborn to adolescent.

Implementation Of A Hospital Medicine Rotation And Curriculum For Internal Medicine Residents, Doris Lin, Chirayu Shah, Erica Lescinskas, Cory Ritter, Lindsey Gay

Faculty, Staff and Students Publications

INTRODUCTION: Hospital medicine is a growing field that focuses not only on expertise in inpatient medicine but also on knowledge of nonclinical health system topics. The traditional model for resident education does not lend itself to learning these topics. We developed a unique ward rotation with a dedicated curriculum called the Resident Inpatient Training Experience (RITE) to address this deficiency.

METHODS: The RITE rotation was initially implemented in the 2013-2014 academic year. The curriculum accompanying the rotation contained four case-based modules that included content on patient safety, quality improvement, cost-conscious care, hospital metrics/reimbursement, physician billing and coding, and transitions of …

Allograft rejection after renal transplantation remains a challenge to overcome. Interleukin (IL)-21, a cytokine with pleiotropic effects, maintains immune homeostasis post-transplantation. Here, we report higher levels of IL-21 in kidney transplant recipients with non-rejection (NR) than in recipients with T cell-mediated rejection (TCMR, P < 0.001) and antibody-mediated rejection (ABMR, P = 0.005). We observed a negative correlation between IL-21 and creatinine (Cr) levels (P = 0.016). The receiving operating characteristic (ROC) curve showed a promising diagnostic value of IL-21 to identify acute rejection with an area under the curve (AUC) of 0.822 (P < 0.001). In contrast, exogenous administration of IL-21 accelerated acute rejection in a comparative translational kidney transplant (KT) mouse model. Reduced IL-21 levels in the peripheral blood were observed in KT mice after IL-21 injection. Further analysis revealed that increased IL-21 levels in the spleen induced proliferation of CD4+ T cells and CD19+ B cells after IL-21 treatment. Our findings suggest a critical function of IL-21 in kidney transplantation and the potential involvement of the IL-21/IL-21R pathway in acute rejection management.

Department of Radiology Faculty Papers

The implantation of penile protheses for the surgical treatment of erectile dysfunction has risen in popularity over the past several decades. Considerable advances have been made in surgical protocol and device design, specifically targeting infection prevention. Despite these efforts, device infection remains a critical problem, which causes significant physical and emotional burden to the patient. The aim of this review is to broaden the discussion of best practices by not only examining practices in urology, but additionally delving into the field of orthopedic surgery to identify techniques and approaches that may be applied to penile prothesis surgery.

BACKGROUND: Neuronal cytoplasmic inclusions containing TAR DNA-binding protein 43 (TDP-43) are a neuropathological feature of several neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), and Alzheimer's Disease (AD). Emerging evidence also indicates that systemic inflammation may be a contributor to the pathology progression of these neurodegenerative diseases.

METHODS: To investigate the role of systemic inflammation in the progression of neuronal TDP-43 pathology, AAV9 particles driven by the UCHL1 promoter were delivered to the frontal cortex of wild-type aged mice via intracranial injections to overexpress TDP-43 or green fluorescent protein (GFP) in corticospinal motor neurons. Animals were then subjected …

Toxicology and Cancer Biology Faculty Publications

Rho GTPases, a family of the Ras GTPase superfamily, are key regulators of the actin cytoskeleton. They were originally thought to primarily affect cell migration and invasion; however, recent advances in our understanding of the biology and function of Rho GTPases have demonstrated their diverse roles within the cell, including membrane trafficking, gene transcription, migration, invasion, adhesion, survival and growth. As these processes are critically involved in cancer initiation, metastasis and therapeutic responses, it is not surprising that studies have demonstrated important roles of Rho GTPases in cancer. Although the majority of data indicates an oncogenic role of Rho GTPases, …

Department of Neurology Faculty Papers

Matrine (MAT), a quinolizidine alkaloid component derived from the root of Sophora flavescens, suppresses experimental autoimmune encephalomyelitis (EAE), the animal model of multiple sclerosis (MS), by inducing the production of immunomodulatory molecules, e.g., IL-10. In an effort to find the upstream pathway(s) of the mechanism underlying these effects, we have tested certain upregulated immunomodulatory molecules. Among them, we found increased levels of IL-27 and IFN-β, one of the first-line MS therapies. Indeed, while low levels of IFN-β production in sera and type I interferon receptor (IFNAR1) expression in spinal cord of saline-treated control EAE mice were detected, they were significantly …
