SIGNIFICANCE: Stroke is the leading cause of chronic disability in the United States. How stroke size affects post-stroke repair and recovery is poorly understood.

AIM: We aim to investigate the effects of stroke size on early repair patterns and determine how early changes in neuronal circuits and networks predict functional outcomes after stroke.

APPROACH: We used wide-field optical imaging, photothrombosis, and the cylinder-rearing assay to examine changes in neuronal circuit and network activity in the context of functional recovery after stroke.

RESULTS: Larger strokes ablating

CONCLUSIONS: These results suggest that diffuse patterns of remapping, and desynchronization and hyperconnectivity of cortical …

Acquired Ductopenia: An Insight Into Imaging Findings, Rachita Khot, Nathan R Shelman, Daniel R Ludwig, Rashmi T Nair, Mark A Anderson, Sudhakar K Venkatesh, Raj Mohan Paspulati, Rex A Parker, Christine O Menias

2020-Current year OA Pubs

Hepatic ductopenia is a pathologic diagnosis characterized by a decrease in the number of intrahepatic bile ducts as a consequence of various underlying etiologies. Some etiologies, such as primary sclerosing cholangitis, primary biliary cholangitis, and ischemic cholangitis, often have distinctive imaging findings. In contrast, other causes such as chronic rejection following liver transplantation, drug-induced biliary injury, infection, malignancy such as lymphoma, and graft-versus-host disease may only have ancillary or non-specific imaging findings. Thus, diagnosing ductopenia in conditions with nonspecific imaging findings requires a multidimensional approach, including clinical evaluation, serological testing, imaging, and liver histology to identify the underlying cause. These …

Barriers And Facilitators To Implementing A Single-Visit, Screen-And-Treat Approach With Thermal Ablation For Cervical Cancer Prevention In Kenya, Harriet Fridah Adhiambo, Thomas Odeny, Et Al.

2020-Current year OA Pubs

Cervical cancer continues to be a major global threat to women's health, with approximately 660,000 women diagnosed annually, 94% of whom are in low- and middle-income countries (LMICs). The high disease burden in LMICs is partly due to suboptimal adoption and widespread implementation of effective preventive interventions. This study explored drivers of implementation success and failure for a future single-visit, screen, and treat approach with thermal ablation (SV-SAT + TA), referred to as TIBA in Kenya. Guided by the Consolidated Framework for Implementation Research (CFIR framework), we conducted in-depth interviews with 34 participants (frontline health workers, health facility managers, and …

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. Broad …

2020-Current year OA Pubs

INTRODUCTION: Alzheimer's disease and related dementias researchers have benefited from deeply phenotyped clinical samples; however, there is a critical need for estimates that generalize to diverse, representative populations. Use of a statistical approach from causal inference, "transport," may allow generalization of findings from clinical samples to other target populations. Here we explore the feasibility and validity of extending results from a clinical sample, the Alzheimer's Disease Neuroimaging Initiative (ADNI), to a community-based target sample, the Atherosclerosis Risk in Communities Study Positron Emission Tomography Amyloid Imaging Study (ARIC-PET) using transport estimation and a standard approach, direct standardization, which itself can be …

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.

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

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 …
