Education Research: Trends of Neurology Clerkships in the United States Amidst a Global Pandemic.

Background And Objectives: To report a 2022 survey of US medical school neurology clerkship directors (CDs) and to compare the results with those of similar surveys conducted in 2005, 2012, and 2017.

Methods: An American Academy of Neurology (AAN) Consortium of Neurology Clerkship Directors (CNCD) workgroup developed the survey sent to all neurology CDs listed in the AAN CNCD database. Comparisons were made with 2005, 2012, and 2017 surveys.

Service Lines, Neurology, and Academic Medicine: Departmental Perspectives, Implementation Strategies, and Keys to Success.

Service lines are increasingly common for organizing multidisciplinary patient care. Concerns regarding impacts of neuroscience service lines were voiced at several national neurology department chair summits, prompting the American Academy of Neurology to convene a Service Lines Workgroup. Neurology department leaders nationally at institutions that had created or considered a neuroscience service line were interviewed to elicit their experiences and lessons learned.

A Qualitative Study of Facilitators, Barriers, and Gender Disparities in Academic Neurology.

Background And Objectives: To understand the challenges and facilitators of a successful academic neurology research career broadly and to identify gender-based disparities specifically.

Methods: In 2019, participants self-identifying as researchers, preregistered for the American Academy of Neurology (AAN) Annual Meeting, ≥7 years out of residency, and authors of ≥1 AAN meeting abstract submission (2006-2009) were selected to participate in the qualitative study (purposeful sampling strategy). To increase diversity, 15 participants were invited by members involved in the AAN until interviews were complete.

Inhibition of the glucocorticoid receptor attenuates proteinuric kidney diseases in multiple species.

Background: Glucocorticoids are the treatment of choice for proteinuric patients with minimal change disease (MCD) and primary focal segmental glomerulosclerosis (FSGS). Immunosuppressive as well as direct effects on podocytes are believed to mediate their actions. In this study, we analyzed the anti-proteinuric effects of inhibition of the glucocorticoid receptor (GR) in glomerular epithelial cells, including podocytes.

DNA binding protein YB-1 is a part of the neutrophil extracellular trap mediation of kidney damage and cross-organ effects.

Open-heart surgery is associated with high morbidity, with acute kidney injury (AKI) being one of the most commonly observed postoperative complications. Following open-heart surgery, in an observational study we found significantly higher numbers of blood neutrophils in a group of 13 patients with AKI compared to 25 patients without AKI (AKI: 12.9±5.

New Aspects of Kidney Fibrosis-From Mechanisms of Injury to Modulation of Disease.

Organ fibrogenesis is characterized by a common pathophysiological final pathway independent of the underlying progressive disease of the respective organ. This makes it particularly suitable as a therapeutic target. The Transregional Collaborative Research Center "Organ Fibrosis: From Mechanisms of Injury to Modulation of Disease" (referred to as SFB/TRR57) was hosted from 2009 to 2021 by the Medical Faculties of RWTH Aachen University and the University of Bonn.

Neurologists' Attitudes Toward Use and Timing of Deep Brain Stimulation.

Objective: We sought to explore current perspectives and attitudes of general neurologists and movement disorder specialists toward deep brain stimulation (DBS) for Parkinson disease (PD), focusing on perspectives on its earlier use in the clinical course of the disease.

Methods: We designed a 30-question online survey comprised of Likert-type, multiple choice, and rank-order questions, which was distributed to 932 neurologist members of the American Academy of Neurology. We analyzed clinicians' sociodemographic information, treatment patterns used for patients with PD, reasons for and against patient referral for DBS, and general attitudes toward DBS.

Understanding How to Strengthen the Neurology Pipeline With Insights From Undergraduate Neuroscience Students.

Despite increased neuroscience interest at the undergraduate level, a significant shortage of neurologists in the United States exists. To better understand how to generate more interest in neurology, specifically at the undergraduate level, we conducted an anonymous cross-sectional online survey comprising 1,085 undergraduates in either neuroscience courses or majoring/minoring in neuroscience from across the United States to better understand their clinical neurology experiences and perspectives. The survey quantitatively and qualitatively assessed students' clinical neurology exposure inside and outside of the classroom, research experiences, and career goals.

Classifying Goliath Grouper () Behaviors from a Novel, Multi-Sensor Tag.

Inertial measurement unit sensors (IMU; i.e., accelerometer, gyroscope and magnetometer combinations) are frequently fitted to animals to better understand their activity patterns and energy expenditure.

Pro-cachectic factors link experimental and human chronic kidney disease to skeletal muscle wasting programs.

Skeletal muscle wasting is commonly associated with chronic kidney disease (CKD), resulting in increased morbidity and mortality. However, the link between kidney and muscle function remains poorly understood. Here, we took a complementary interorgan approach to investigate skeletal muscle wasting in CKD.

Key metalloproteinase-mediated pathways in the kidney.

Matrix metalloproteinases (MMPs) and a disintegrin and metalloproteinases (ADAMs) belong to the metzincin family of zinc-containing multidomain molecules, and can act as soluble or membrane-bound proteases. These enzymes inactivate or activate other soluble or membrane-expressed mediator molecules, which enables them to control developmental processes, tissue remodelling, inflammatory responses and proliferative signalling pathways. The dysregulation of MMPs and ADAMs has long been recognized in acute kidney injury and in chronic kidney disease, and genetic targeting of selected MMPs and ADAMs in different mouse models of kidney disease showed that they can have detrimental and protective roles.

Attracting neurology's next generation: A qualitative study of specialty choice and perceptions.

Objectives: To better understand the reasons medical students select or avoid a career in neurology by using a qualitative methodology to explore these factors, with the long-term objective of attracting more graduates to the field.

Methods: In 2017, 27 medical students and 15 residents participated in 5 focus groups, and 33 fourth-year medical students participated in semistructured individual interviews. Participants were asked predefined open-ended questions about specialty choice, experiences in their basic neuroscience course and neurology clerkship, and perceptions about the field.

Immune Sensing of Synthetic, Bacterial, and Protozoan RNA by Toll-like Receptor 8 Requires Coordinated Processing by RNase T2 and RNase 2.

Human toll-like receptor 8 (TLR8) activation induces a potent T helper-1 (Th1) cell response critical for defense against intracellular pathogens, including protozoa. The receptor harbors two distinct binding sites, uridine and di- and/or trinucleotides, but the RNases upstream of TLR8 remain poorly characterized. We identified two endolysosomal endoribonucleases, RNase T2 and RNase 2, that act synergistically to release uridine from oligoribonucleotides.

The nucleic acid binding protein YB-1-controlled expression of CXCL-1 modulates kidney damage in liver fibrosis.

Acute kidney injury is a common complication of advanced liver disease and increased mortality of these patients. Here, we analyzed the role of Y-box protein-1 (YB-1), a nucleic acid binding protein, in the bile duct ligation model of liver fibrosis and monitored liver and subsequent kidney damage. Following bile duct ligation, both serum levels of liver enzymes and expression of hepatic extracellular matrix components such as type I collagen were significantly reduced in mice with half-maximal YB-1 expression (Yb1) as compared to their wild-type littermates.

The YB-1:Notch-3 axis modulates immune cell responses and organ damage in systemic lupus erythematosus.

Systemic lupus erythematosus (SLE) is an autoimmune disease and lupus nephritis is a major risk factor for morbidity and mortality. Notch-3 signaling induced by membrane-bound or soluble ligands such as YB-1 constitutes an evolutionarily conserved pathway that determines major decisions in cell fate. Mass spectrometry of extracellular YB-1 in sera from patients with SLE and lupus-prone mice revealed specific post-translational guanidinylation of two lysine residues within the highly conserved cold-shock domain of YB-1 (YB-1-G).

Association between rapid weather changes and incidence of chiefly cardiovascular complaints in the emergency department.

Introduction: Studies suggest that there is an association between weather and cardiovascular disease (CVD) related visits in emergency departments (ED).

Methods: We used a case-crossover study design to investigate the association between ED visits for CVD and changes in temperature, atmospheric pressure, and relative humidity. Patient and weather data from the years 2014 and 2015 were used to investigate relevance of changes associated with weather in the frequency of CVD-related ED visits.

A Novel Role for GATA3 in Mesangial Cells in Glomerular Development and Injury.

Background: GATA3 is a dual-zinc finger transcription factor that regulates gene expression in many developing tissues. In the kidney, GATA3 is essential for ureteric bud branching, and mice without it fail to develop kidneys. In humans, autosomal dominant mutations can cause renal aplasia as part of the hypoparathyroidism, renal dysplasia, deafness (HDR) syndrome that includes mesangioproliferative GN.

High-fat diet-induced obesity causes an inflammatory microenvironment in the kidneys of aging Long-Evans rats.

Background: Obesity is a risk factor for chronic kidney disease (CKD). While the exact mechanisms remain unclear, inflammation may be a consequence of obesity that directly impacts the kidneys. The aim of this study was to examine the inflammatory status of the kidneys and potential ongoing renal damage, i.

American Academy of Neurology members' preparedness to treat sexual and gender minorities.

Objective: To measure the attitudes and knowledge of American Academy of Neurology (AAN) member neurologists in caring for sexual and gender minority (SGM) patients (e.g., those who identify in the lesbian, gay, bisexual, transgender, queer, or questioning [LGBTQ+] spectrum) to inform future educational offerings.

Production and formulation of a new low-cost biosurfactant to remediate oil-contaminated seawater.

The aim of the present study was to produce biosurfactants using three bacterial strains (Pseudomonas cepacia CCT6659, Bacillus methylotrophicus UCP 1616 and Bacillus cereus UCP 1615) cultivated in mineral medium containing different carbon (glucose, sucrose, molasses and waste frying oil) and nitrogen [NHNO, (NH)SO, peptone, yeast extract and corn steep liquor] sources. B. cereus stood out as the best biosurfactant producer when inoculated with a 1.

Identification of platelet-derived growth factor C as a mediator of both renal fibrosis and hypertension.

Platelet-derived growth factors (PDGF) have been implicated in kidney disease progression. We previously found that PDGF-C is upregulated at sites of renal fibrosis and that antagonism of PDGF-C reduces fibrosis in the unilateral ureteral obstruction model. We studied the role of PDGF-C in collagen 4A3 ("Alport") mice, a model of progressive renal fibrosis with greater relevance to human kidney disease.

YB-1 increases glomerular, but decreases interstitial fibrosis in CNI-induced nephropathy.

Calcineurin inhibitors (CNIs) are a cornerstone of the current treatment in solid organ transplantation and autoimmune disease. However, CNIs also bear deleterious effects as they cause glomerular and tubulointerstitial fibrosis in the kidney. We recently identified Y-box protein-1 (YB-1) as a novel downstream effector of CNI-signaling in the cytoplasm of glomerular cells.

CD44 is required for the pathogenesis of experimental crescentic glomerulonephritis and collapsing focal segmental glomerulosclerosis.

A key feature of glomerular diseases such as crescentic glomerulonephritis and focal segmental glomerulosclerosis is the activation, migration and proliferation of parietal epithelial cells. CD44-positive activated parietal epithelial cells have been identified in proliferative cellular lesions in glomerular disease. However, it remains unknown whether CD44-positive parietal epithelial cells contribute to the pathogenesis of scarring glomerular diseases.
