© 2020 by the authors. Li-censee MDPI, Basel, Switzerland. Early diagnosis of Alzheimer’s disease (AD) is a crucial starting point in disease man-agement. Blood-based biomarkers could represent a considerable advantage in providing AD-risk information in primary care settings. Here, we report new data for a relatively unknown blood-based biomarker that holds promise for AD diagnosis. We evaluate a p53-misfolding conformation rec-ognized by the antibody 2D3A8, also named Unfolded p53 (U-p532D3A8+), in 375 plasma samples derived from InveCe.Ab and PharmaCog/E-ADNI longitudinal studies. A machine learning approach is used to combine U-p532D3A8+ plasma levels with Mini-Mental State Examination (MMSE) and apolipoprotein E …

Intergenerational Associations Of Adverse Birth Outcomes: A Surveillance Report, Dong Liu, Ge Lin, Dejun Su, James M. Alexender, Xiaoting Sun, Ming Qu

School of Medicine Faculty Publications

Nebraska births between 1995 and 2005 were followed until 2018 to look for intergenerational associations of low birth weight (LBW) and preterm birth (PTB). Results from generalized estimating equations revealed that mothers born LBW preterm were more likely to deliver LBW (adjusted OR 1.94, 95% CI 1.39–2.71) or preterm (adjusted OR 1.65, 95% CI 1.20–2.27) than mothers born with normal weight or at term. In addition, mothers who had an LBW sibling were 44% more likely to have an LBW infant (OR 1.44, 95% CI 1.04–2.00). A consistent finding was also observed for mothers who had a PTB sibling (OR …

Metastatic Squamous Cell Carcinoma: A Cautionary Tale, Colby Shreve, Chase Shropshire, David G. Cotter

School of Medicine Faculty Publications

Cutaneous squamous cell carcinoma (cSCC) typically arises from a malignant proliferation of keratinocytes. It is the second most common cancer in the United States and typically affects older white men. Risk factors for cSCC include ultraviolet radiation exposure, light skin tone, and immunosuppression. Although metastasis in cSCC is rare, primary tumor characteristics such as location, size, and depth of invasion, among others, can help risk-stratify lesions for local recurrence, metastatic events, and death. We present a case of primary cutaneous metastatic squamous cell carcinoma masquerading as a cyst on the left temple of a 73-year-old Caucasian man following numerous treatments …

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.

Background: Outcomes after peripheral nerve injuries are poor despite current nerve repair techniques. Currently, there is no conclusive evidence that mammalian axons are capable of spontaneous fusion after transection. Notably, certain invertebrate species are able to auto-fuse after transection. Although mammalian axonal auto-fusion has not been observed experimentally, no mammalian study to date has demonstrated regenerating axolemmal membranes contacting intact distal segment axolemmal membranes to determine whether mammalian peripheral nerve axons have the intrinsic mechanisms necessary to auto-fuse after transection.Objective: This study aims to assess fusion competence between regenerating axons and intact distal segment axons by enhancing axon regeneration, delaying …

Middle Ear Salivary Choristoma: A Rare Case Report And Update On Congenital Associations, Facial Nerve Involvement, And Treatment Strategies, Allen Young, Lauren Evans, Matthew Ng Aug 2020

Middle Ear Salivary Choristoma: A Rare Case Report And Update On Congenital Associations, Facial Nerve Involvement, And Treatment Strategies, Allen Young, Lauren Evans, Matthew Ng

School of Medicine Faculty Publications

Salivary gland choristoma is an extremely rare middle ear mass and is hypothesized to be caused by second branchial arch developmental anomalies. We present a 14-year-old girl with Dandy-Walker syndrome and conductive hearing loss. Middle ear exploration revealed a large middle ear mass with absent incus and stapes and displaced facial nerve. The mass was completely excised with histological confirmation of salivary gland choristoma. Her hearing was improved with bone-anchored hearing aids (BAHA). As facial nerve involvement is common, physicians should consider partial excision to avoid facial nerve palsy. Hearing restoration can be achieved with OCR or BAHA.

Bk Virus Nephropathy: Prevalence, Impact And Management Strategies, Rajeev Sharma, Mareena Zachariah

School of Medicine Faculty Publications

BK virus reactivation as a result of therapeutic immunosuppression following renal transplant can result in BK polyomavirus nephropathy and renal allograft loss. This is a complex and challenging clinical problem with a range of management options and practices reported in literature. The current standard for early diagnosis and treatment is surveillance by measuring viral DNA in blood using qPCR. Immunosuppression reduction is the cornerstone of effective management but is associated with a risk of acute rejection following treatment.

Background: Skin cancer incidence has been rapidly increasing over the past 2 decades, and the resulting defects from excision have significant aesthetic and functional implications. In particular, wound coverage for large scalp and forehead defects with calvarial exposure can lead to hairline distortion, contour irregularities, and alopecia. We describe a 2-stage technique for scalp reconstruction, which preserves the normal hairline, covers exposed bone with vascularized tissue, and restores an aesthetic soft-tissue contour. Methods: This is a retrospective case series of 13 adults with ages ranging from 50 to 89 years. All patients underwent Mohs surgery on the forehead or scalp …

School of Medicine Faculty Publications

Exogenous lipoid pneumonia is a rare and frequently misdiagnosed lung disease. It occurs as an inflammatory reaction secondary to either aspiration or inhalation of lipids. Our patient had a history significant for recurrent pneumonia and the use of mineral oil for chronic constipation. A chest computed tomography showed multifocal consolidative opacities with areas of low attenuation, highly suspicious of exogenous lipid pneumonia. The diagnosis was confirmed with combined bronchoalveolar lavage and transbronchial lung biopsy that showed lipid-laden macrophages consistent with exogenous lipoid pneumonia. After thorough medication review, apart from mineral oil, no other contributing factors were found. A diagnosis of …

An Actigraphy-Based Validation Study Of The Sleep Disorder Inventory In The Nursing Home, Gunnhild J. Hjetland, Inger Hilde Nordhus, Ståle Pallesen, Jeffrey Cummings, Rochelle E. Tractenberg, Eirunn Thun, Eirin Kolberg, Elisabeth Flo

School of Medicine Faculty Publications

Background: Disrupted sleep is common among nursing home patients with dementia and is associated with increased agitation, depression, and cognitive impairment. Detecting and treating sleep problems in this population are therefore of great importance, albeit challenging. Systematic observation and objective recordings of sleep are time-consuming and resource intensive and self-report is often unreliable. Commonly used proxy-rated scales contain few sleep items, which affects the reliability of the raters' reports. The present study aimed to adapt the proxy-rated Sleep Disorder Inventory (SDI) to a nursing home context and validate it against actigraphy. Methods: Cross-sectional study of 69 nursing home patients, 68% …

Recent Advances In Understanding And Management Of Bronchopulmonary Dysplasia, Vineet Bhandari, Mitali Sahni

School of Medicine Faculty Publications

© 2020 Sahni M and Bhandari V. In the current era, the survival of extremely low-birth-weight infants has increased considerably because of new advances in technology; however, these infants often develop chronic dysfunction of the lung, which is called bronchopulmonary dysplasia (BPD). BPD remains an important cause of neonatal mortality and morbidity despite newer and gentler modes of ventilation. BPD results from the exposure of immature lungs to various antenatal and postnatal factors that lead to an impairment in lung development and aberrant growth of lung parenchyma and vasculature. However, we still struggle with a uniform definition for BPD that …
