Plasma Nfl And Cognitive Functioning In Older Adults: The Moderating Role Of Hdl Cholesterol, Ramkrishna K Singh, Semere Bekena, Yiqi Zhu, Carlos Cruchaga, Steven E Arnold, Beau M Ances, Ganesh M Babulal

2020-Current year OA Pubs

BACKGROUND AND OBJECTIVES: Plasma neurofilament light chain (NfL) is a marker of neuroaxonal injury associated with cognitive decline. High-density lipoprotein (HDL) cholesterol has neuroprotective properties, but its interaction with neurodegeneration remains unclear. This study examined whether HDL moderates the association between NfL and cognitive performance.

METHODS: Baseline data from 417 participants in the Aging Adult Brain Connectome study were analyzed. Plasma NfL and HDL were measured via Simoa and enzymatic assays; cognition was assessed using Montreal Cognitive Assessment (MoCA) and Preclinical Alzheimer Cognitive Composite (PACC). Generalized linear models were used to evaluate NfL and HDL interactions, adjusting for demographics. Sensitivity …

Feasibility Of Endobronchial Ultrasound Guided Miniforceps Biopsy For Pd-L1 Expression And Quantitative Tissue Analysis, Max T Wayne, Nathaniel G Moulton, Cody Weimholt, Praveen Chenna, Alexander C Chen

2020-Current year OA Pubs

BACKGROUND: Testing for targeting programmed death ligand 1 (PD-L1) is standard of care for patients with newly diagnosed non-small cell lung cancer (NSCLC) but is only approved for use with core biopsy specimens. Endobronchial ultrasound guided miniforceps biopsy (EBUS-MFB) is an approach to obtain core biopsy material but data assessing the ability of EBUS-MFB to adequately test for PD-L1 is lacking. We evaluate the feasibility of EBUS-MFB to acquire adequate tissue for PD-L1 testing and look to compare the quality of specimens between EBUS-MFB and endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) using a standard method of tissue analysis.

Chronic Recurrent Multifocal Osteomyelitis-Like Paraneoplastic Syndrome As Initial Presentation Of Nodular Sclerosis Classical Hodgkin Lymphoma, Michel Attieh, Seyed Reza Taha, Selim Nasser, Fouad Boulos

2020-Current year OA Pubs

Hodgkin lymphoma (HL) presenting with initial skeletal symptoms as a paraneoplastic phenomenon is extremely rare. Herein, we report the case of a 26-year-old man with nodular sclerosis classical HL (NSCHL) who presented with low back pain as the initial symptom. Imaging studies were unremarkable except for right S1-S2 sacral marrow edema on MRI, and multiple biopsies showed only inflammatory changes, resulting in a tentative diagnosis of chronic recurrent multifocal osteomyelitis. Later in the course of the disease, after performing routine series of MRIs, lymphadenopathy was finally detected. Core biopsies of the axillary and pelvic lymph nodes subsequently confirmed the diagnosis …

2020-Current year OA Pubs

Intramedullary nail fixation is the "gold standard" for surgical intervention of femoral fractures. While many aspects of nail design and patient anatomy have received specific focus, anatomic variations in proximal femoral geometry and greater trochanteric height variation have been poorly studied. Understanding the potential relationship of the greater trochanter to patient demographics may provide an opportunity to improve implant placement. Retrospective review of x-ray and computed tomography images of the proximal femur was performed. Inclusion criteria consisted of skeletally mature patients over 18 years old with imaging of the proximal femur. Inclusion criteria identified 296 patients. Mean age of included …

Cervical cancer is preventable; however, it remains the leading cause of death in low- and middle-income countries (LMICs). Women with HIV (WWHs) have a sixfold higher risk of developing and dying from cervical cancer than women without HIV. Cervical cancer can be prevented by vaccination against high-risk human papillomaviruses (hrHPVs) and by screening for and treating precancer cervical lesions. While these preventive measures are routinely available to WWHs in developed countries, they are lacking in most LMICs, where the burden of HIV and cervical cancer is the highest. To prevent cervical cancer deaths among WWHs in LMICs, it is imperative …

Diagnosis And Management Of Gastroesophageal Reflux Disease: Current Insights, Abhinav Vayal-Veettil, C Prakash Gyawali

2020-Current year OA Pubs

Gastroesophageal reflux disease (GERD) results from retrograde movement of gastric content into the esophagus and beyond, resulting in symptoms, mucosal injury and long-term complications. Typical symptoms of heartburn and regurgitation are highly suggestive of GERD, but atypical presentations require careful evaluation to rule out alternative diagnoses. Diagnostic modalities, including endoscopy, ambulatory reflux monitoring, and high-resolution manometry, play a pivotal role in confirming GERD and guiding personalized treatment. Management strategies consist of lifestyle modifications, pharmacologic therapy with anti-secretory agents, and adjunctive treatments such as alginates and baclofen. For refractory cases, surgical and endoscopic interventions offer durable symptom relief. Complications of GERD …

Surgeons, Physiatrists And Neurologists Speaking "Edx And Nerve Surgery": A Paradigm Shift For Nerve Injured Patients, Deng Pan, Aneri U Patel, J Megan Patterson, Anna Rose Johnson, Travis Gordon, Susan E Mackinnon

2020-Current year OA Pubs

Surgeons' ability to interpret electrodiagnostic (EDX) studies has greatly enhanced patient selection and outcome for nerve surgeries as it has informed our understanding of the classification of nerve injury. EDX measures axons present, lost, or demyelinated. It does not measure an area where axons experience chronic ischemia, making a Sunderland Zero nerve injury a clinical diagnosis that should be suspected when patients have normal EDX, decreased recruitment on electromyography (EMG), and no atrophy. Only observation of recovery in the earliest postoperative period would confirm a Sunderland Zero. In this article, we present an expanded classification of nerve injury, highlighting Sunderland …

Acute Metabolic Decompensation After Liver Transplant In A Patient With Maple Syrup Urine Disease, Shao Ching Tu, Marium Khan, Katie Wolfe, Sakil S Kulkarni, Elizabeth Toolan, Dorothy K Grange

2020-Current year OA Pubs

Maple syrup urine disease (MSUD) is an inborn error of metabolism characterized by the accumulation of branched-chain amino acids (leucine, isoleucine, and valine) caused by a defect in the branched-chain alpha-keto acid dehydrogenase complex. Liver transplant is an effective therapy for MSUD, and patients can usually tolerate a regular diet after transplant without symptomatic metabolic decompensation. Most post-transplant patients do not follow a sick-day diet. We report a case of a 7-year-old male with MSUD Type IA, status post-liver transplant at 2 years of age, who presented with profound encephalopathy following poor oral intake and vomiting for 3 days.
