Depression Secondary To Isotretinoin – A Case Report, Rohan Karkra, Megha Sadashiv, Kishor M

Digital Journal of Clinical Medicine

Depression is one of the leading causes of morbidity in the world and significantly affects the lives of people suffering from it. The exact cause of depression has not been established and it is believed to be a complex play between various social, biological, environmental, personal factors. A relatively rare but distinct cause includes pharmacological agents.

In this case report, we describe the case of a 17-year-old girl who developed depression with psychotic symptoms on two occasions, both preceded by a history of Isotretinoin use. She was admitted and treated with anti-psychotics and psychotherapy with significant improvement in her mental …

BACKGROUND

Intertrochanteric fracture is a common orthopedic condition characterized by extracapsular fractures of the proximal femur that occur between the greater and lesser trochanter with predominance in elderly population, especially those with osteoporosis, wherein even a low energy mechanism is enough to cause the fracture.

There is an observed female predominance with ratio between 2:1 and 8:1. [1,2]

Commonly observed symptoms include shortened and externally rotated limb, pain and bony tenderness around the hip joint, inability to bear weight on the affected limb to name a few.

Management depends upon age of patient, nature of the fracture, number of comminuted …

A Rare Case Of Extra-Ventricular Supra-Sellar Neurocytoma – A Diagnostic Conundrum, Rohan Karkra, Suchitha Satish, Peri Keerthi

Digital Journal of Clinical Medicine

The brain and its associated structures are often the primary source or site of metastases for many tumors. Neurocytoma is a relatively rare neuronal neoplasm, first described as an intra-ventricular tumor that is not known to be very aggressive. It constitutes less than 0.5% of CNS neoplasms. Extraventricular Neurocytoma (EVN) is an extremely rare variant, of which only 12 cases have ever been reported in the supra-sellar region. In all of these 12 cases, the patient was initially misdiagnosed; hence, this condition is a diagnostic conundrum. Grossly, the tumor is firm and smooth with extensive blood supply and fibrous tissue. …

Comparison Of Conventional Pap Smear And Manual Liquid Based Cytology With P16 Marker In Screening For Cervical Cancer In Indian Tertiary Healthcare Setups In Mysuru, Gayathri Sureshkumar Nair, Nandini Manoli, Nandish Manoli

Digital Journal of Clinical Medicine

In India, there are 20.2 per 100000 new cases of Cervical Cancer diagnosed and 11.1 per 100000 deaths annually accounting for more than one fifths of global cervical cancer deaths. [1] Thus, due to an absence of a national immunization program to cover human papillomavirus (HPV) vaccination and lack of accessible cervical cancer screening, the disease is characterized by late detection, lack of access to affordable and quality health care, and high mortality rates. [2]

Papanicolaou Smear Test was a novel invention by Dr George Papanicolaou in the year 1927 which gained maximum popularity in 1950 as a screening test …

Aggregation of the microtubule-associated protein tau characterizes tauopathies, including Alzheimer’s disease and frontotemporal lobar degeneration (FTLD-Tau). Gene expression regulation of tau is complex and incompletely understood. Here we report that the human tau gene (MAPT) generates two circular RNAs (circRNAs) through backsplicing of exon 12 to either exon 7 (12→7 circRNA) or exon 10 (12→10 circRNA). Both circRNAs lack stop codons. The 12→7 circRNA contains one start codon and is translated in a rolling circle, generating a protein consisting of multimers of the microtubule-binding repeats R1–R4. For the 12→10 circRNA, a start codon can be introduced by two …

Epigenetic Basis Of Diabetic Vasculopathy, Theja Bhamidipati, Manishekhar Kumar, Sumit S. Verma, Sedat Kacar, Diamond Reese, Michelle M. Martinez, Malgorzata M. Kamocka, Kenneth W. Dunn, Chandan K. Sen, Kanhaiya Singh

Einstein Health Papers

Type 2 diabetes mellitus (T2DM) causes peripheral vascular disease because of which several blood-borne factors, including vital nutrients fail to reach the affected tissue. Tissue epigenome is sensitive to chronic hyperglycemia and is known to cause pathogenesis of micro- and macrovascular complications. These vascular complications of T2DM may perpetuate the onset of organ dysfunction. The burden of diabetes is primarily because of a wide range of complications of which nonhealing diabetic ulcers represent a major component. Thus, it is imperative that current research help recognize more effective methods for the diagnosis and management of early vascular injuries. This review addresses …

A Text-Based Smoking Cessation Intervention For Sexual And Gender Minority Groups: Protocol For A Feasibility Trial, Irene Tami-Maury, Rebecca Klaff, Allison Hussin, Nathan Grant Smith, Shine Chang, Lorna Mcneill, Lorraine R Reitzel, Sanjay Shete, Lorien C Abroms

Faculty, Staff and Student Publications

BACKGROUND: Smoking among sexual and gender minority (SGM) groups, which include lesbian, gay, bisexual, transgender, and queer individuals, has been reported to be highly prevalent. This is attributed to several factors, including minority-specific stress and targeted tobacco marketing. Therefore, this population is at an increased risk for tobacco-related diseases. SMS text messaging programs have been found to be effective for smoking cessation and appeal to traditionally hard-to-reach populations over other interventions. It has also been suggested that targeted and tailored interventions could be more effective among SGM smokers because they can be designed to assure a safe, validating health care …

An association between the BRAFV600E mutation and the clinicopathological progression of papillary thyroid microcarcinoma (PTMC) has been suggested. We aimed to summarize the relevant literature and determine the predictive value of BRAFV600E mutation in predicting clinical outcomes and risk stratification in patients with PTMC. A systematic search using PubMed, Cochrane, and Embase up to February 2020 was performed. A total of 33 studies met the inclusion criteria, resulting in a pool of 8838 patients, of whom 5043 (57.1%) patients were positive for BRAFV600E mutation. Tumors with positive BRAFV600E mutation had a higher tendency for multifocality (RR = 1.09, 95%CI = …

Development Of A Crosslinked Osteochondral Xenograft And A Collagen Stabilizing Intra-Articular Injection To Remediate Cartilage Focal Lesions To Prevent Osteoarthritis, Mark Lewis Mosher

Theses and Dissertations

Osteoarthritis is one of the most common causes of disability in adults in America. It is a progressive and degenerative disease where the articular cartilage is broken down and lost from the surfaces of bones causing chronic pain and swelling in the joints, and currently has no cure. The most commonly osteoarthritis starts from a focal lesion on the cartilage surface, which will expand on the surface and downwards through the thickness of the tissue. The current gold standard for correcting cartilage focal lesions is the osteochondral autograft/allograft transplantation (OAT), which replaces the defect with a fresh osteochondral graft. The …

Faculty, Staff and Student Publications

Friedreich's ataxia is an incurable disease caused by frataxin (FXN) protein deficiency, which is mostly induced by GAA repeat expansion in intron 1 of the FXN gene. Here, we identified antisense oligonucleotides (ASOs), complementary to two regions within the first intron of FXN pre-mRNA, which could increase FXN mRNA by ∼2-fold in patient fibroblasts. The increase in FXN mRNA was confirmed by the identification of multiple overlapping FXN-activating ASOs at each region, two independent RNA quantification assays, and normalization by multiple housekeeping genes. Experiments on cells with the ASO-binding sites deleted indicate that the ASO-induced FXN activation was driven by …

BACKGROUND: PI3K/mTOR inhibition leads to apoptosis of NOTCH1-mutant head and neck squamous cell carcinoma (HNSCC) cells. We tested the efficacy of the PI3K/mTOR inhibitor bimiralisib in patients with NOTCH1-mutant HNSCC.

METHODS: Patients with recurrent/metastatic NOTCH1-mutant HNSCC who had progressed during chemotherapy and immunotherapy received bimiralisib until unacceptable toxicity or progression. To assess whether NOTCH1 mutations can be detected in blood, we measured circulating tumor DNA (ctDNA). To assess activated NOTCH1 protein levels, we quantitated cleaved NOTCH1 (cl-NOTCH) by immunohistochemistry.

RESULTS: Eight patients were treated, and 6 were evaluable for response. The objective response rate was 17%. For all 8 patients, …

A General Catalyst Controlled Route To Prostaglandin F2a, Laura Cunningham, Sourabh Mishra, Leon Matthews, Stephen P Fletcher

Faculty, Staff and Student Publications

We report a general, catalyst-controlled route to prostaglandin F2_α and its analogues. The approach uses a Rh-catalyzed dynamic kinetic asymmetric Suzuki–Miyaura coupling reaction between a racemic bicyclic allyl chloride and alkenyl boronic esters bearing chiral alcohols to give cyclopentyl intermediates bearing 3 contiguous stereocenters. The route provides advanced intermediates in 99% ee as a single diastereoisomer in all cases examined, with the absolute stereochemistry of the cyclopentane core controlled by the ligand. Intermediates that could be used to produce prostaglandin analogues such as bimatoprost, latanoprost, fluprostenol, and cloprostenol were synthesized. The final two stereocenters were installed via Pd-catalyzed Tsuji–Trost …

In late August 2021, a boy aged 7 years was bitten by a bat while he was playing outside his apartment home in Medina County, Texas. He informed his parents; however, no rabies postexposure prophylaxis (PEP) was sought because there were no visible bite marks, and the family was unaware that contact with a bat, including in the absence of visible bite marks, might cause rabies. Approximately 2 months later, the child was hospitalized for altered mental status, seizures, and hypersalivation and ultimately received a diagnosis of rabies. Experimental therapies were attempted; however, the child died 22 days after symptom …

Faculty, Staff and Student Publications

Background

Sucrose nonfermenting-1 (SNF1)-related protein kinases (SnRKs) play crucial roles in plant signaling pathways and stress adaptive responses by activating protein phosphorylation pathways. However, there have been no comprehensive studies of the SnRK gene family in the widely planted salt-tolerant tree species Casuarina equisetifolia. Here, we comprehensively analyze this gene family in C. equisetifolia using genome-wide identification, characterization, and profiling of expression changes in response to salt stress.

Results

A total of 26 CeqSnRK genes were identified, which were divided into three subfamilies (SnRK1, SnRK2, and SnRK3). The intron–exon structures and protein‑motif compositions were similar within each subgroup but …

Samples were loaded by distraction until failure. The stiffness, yield load, and ultimate load were compared between each fixation method. No difference in stiffness of the constructs was detected between groups. Yield load and ultimate load for the HCSTB group was greater than the TB group, the HCS group, and the Plate group. CBLO …

Objective Structured Clinical Examination For Intraoperative Hypotension And Hypertension Management, Andrew Mcginity, James David Ingram

Doctoral Projects

Managing intraoperative hypotension and hypertension is a non-technical skill anesthesia providers need to maintain patient safety. Upon transitioning from didactic training to clinical training, SRNAs may find it difficult to manage a patient’s blood pressure intraoperatively. The ultimate consequence of the delayed or improper treatment of intraoperative blood pressure perturbations is end-organ damage at the patient’s expense. Unintentionally causing a patient harm will lead to an SRNA losing confidence in their abilities. This OSCE is intended to increase SRNA confidence and competence regarding intraoperative hypotension and hypertension management before entering the clinical arena.

The hypotension and hypertension management tools and …

Sanders-Brown Center on Aging Faculty Publications

Introduction: Vascular contributions to cognitive impairment and dementia (VCID) are a leading cause of dementia. An underappreciated, modifiable risk factor for VCID is hyperhomocysteinemia (HHcy), defined by elevated levels of plasma homocysteine, most often due to impaired B vitamin absorption in aged persons. Studies aimed at identifying neuropathologic features and gene expression profiles associated with HHcy have been lacking.

Methods: A subset of research volunteers from the University of Kentucky Alzheimer’s Disease Research Center longitudinal cohort came to autopsy and had ante mortem plasma homocysteine levels available. Brain tissue and blood plasma drawn closest to death were used to measure …

Genotype Classification Of Moraxella Bovis Using Maldi-Tof Ms Profiles, Hannah G. Olson, John Dustin Loy, Michael L. Clawson, Emily L. Wynn, Matthew M. Hille

Nebraska Center for Virology: Faculty Publications

Moraxella bovis (M. bovis) is regarded as a causative agent of infectious bovine keratoconjunctivitis (IBK), the most common ocular disease of cattle. Recently, whole genome sequencing identified the presence of two distinct genotypes within M. bovis that differ in chromosome content, potential virulence factors, as well as prophage and plasmid profiles. It is unclear if the genotypes equally associate with IBK or if one is more likely to be isolated from IBK lesions. We utilized 39 strains of M. bovis that had previously undergone whole genome sequencing and genotype classification to determine the utility of matrix-assisted laser desorption/ionization …

Lipoprotein(a) (Lp(a)) represents a unique subclass of circulating lipoprotein particles and consists of an apolipoprotein(a) (apo(a)) molecule covalently bound to apolipoprotein B-100. The metabolism of Lp(a) particles is distinct from that of low-density lipoprotein (LDL) cholesterol, and currently approved lipid-lowering drugs do not provide substantial reductions in Lp(a), a causal risk factor for cardiovascular disease. Somatic genome editing has the potential to be a one-time therapy for individuals with extremely high Lp(a). We generated an LPA transgenic mouse model expressing apo(a) of physiologically relevant size. Adeno-associated virus (AAV) vector delivery of CRISPR-Cas9 was used to disrupt the LPA transgene in …
