Associations Between Atrial Cardiopathy And Cerebral Amyloid: The Aric-Pet Study, Michelle C Johansen, Thomas H Mosley, David S Knopman, Dean F Wong, Chiadi Ndumele, Amil M Shah, Scott D Solomon, Rebecca F Gottesman

Open Access Publications

Background Atrial fibrillation (AF) is a risk factor for cognitive decline, possibly from silent brain infarction. Left atrial changes in structure or function (atrial cardiopathy) can lead to AF but may impact cognition independently. It is unknown if AF or atrial cardiopathy also acts on Alzheimer disease-specific mechanisms, such as deposition of β-amyloid. Methods and Results A total of 316 dementia-free participants from the ARIC (Atherosclerosis Risk in Communities) study underwent florbetapir positron emission tomography, electrocardiography, and 2-dimensional echocardiography. Atrial cardiopathy was defined as ≥1: (1) left atrial volume index >34 mL/m

2020-Current year OA Pubs

OBJECTIVE: The study objective was to investigate the progression of uncorrected mild aortic insufficiency and its impact on survival and functional status after left ventricular assist device implantation.

METHODS: We retrospectively reviewed 694 consecutive patients who underwent implantation of a continuous-flow left ventricular assist device between January 2006 and March 2018. Pre-left ventricular assist device transthoracic echocardiography identified 111 patients with mild aortic insufficiency and 493 patients with trace or no aortic insufficiency. To adjust for differences in preoperative factors, propensity score matching was used, resulting in 101 matched patients in each of the mild aortic insufficiency and no aortic …

Brain Function Distinguishes Female Carriers And Non-Carriers Of Familial Risk For Autism, Adam T Eggebrecht, Ally Dworetsky, Zoë Hawks, Rebecca Coalson, Babatunde Adeyemo, Savannah Davis, Daniel Gray, Alana Mcmichael, Steven E Petersen, John N Constantino, John R Pruett

2020-Current year OA Pubs

BACKGROUND: Autism spectrum disorder (ASD) is characterized by high population-level heritability and a three-to-one male-to-female ratio that occurs independent of sex linkage. Prior research in a mixed-sex pediatric sample identified neural signatures of familial risk elicited by passive viewing of point light motion displays, suggesting the possibility that both resilience and risk of autism might be associated with brain responses to biological motion. To confirm a relationship between these signatures and inherited risk of autism, we tested them in families enriched for genetic loading through undiagnosed ("carrier") females.

METHODS: Using functional magnetic resonance imaging, we examined brain responses to passive …

Covid-19-Associated Acute Kidney Injury: Consensus Report Of The 25th Acute Disease Quality Initiative (Adqi) Workgroup, Mitra K Nadim, Anitha Vijayan, Et Al

Open Access Publications

Kidney involvement in patients with coronavirus disease 2019 (COVID-19) is common, and can range from the presence of proteinuria and haematuria to acute kidney injury (AKI) requiring renal replacement therapy (RRT; also known as kidney replacement therapy). COVID-19-associated AKI (COVID-19 AKI) is associated with high mortality and serves as an independent risk factor for all-cause in-hospital death in patients with COVID-19. The pathophysiology and mechanisms of AKI in patients with COVID-19 have not been fully elucidated and seem to be multifactorial, in keeping with the pathophysiology of AKI in other patients who are critically ill. Little is known about the …

Inherited Risk For Autism Through Maternal And Paternal Lineage, Dan Bai, Natasha Marrus, Benjamin Hon Kei Yip, Abraham Reichenberg, John N Constantino, Sven Sandin

2020-Current year OA Pubs

BACKGROUND: Autism spectrum disorder (ASD) is highly familial, with a positively skewed male-to-female ratio that is purported to arise from the so-called female protective effect. A serious implication of a female protective effect is that familial ASD liability would be expected to aggregate asymptomatically in sisters of affected probands, who would incur elevated rates of ASD among their offspring. Currently, there exist no data on second-generation recurrence rates among families affected by ASD.

METHODS: We analyzed data from the Swedish National Patient Register and the Multi-Generation Register for a cohort of children born between 2003 and 2012. ASD was ascertained …

Adrenal Insufficiency Is A Contraindication For Omalizumab Therapy In Mast Cell Activation Disease: Risk For Serum Sickness, G J Molderings, L B Weinstock, Et Al.

2020-Current year OA Pubs

Omalizumab is an effective therapeutic humanized murine IgE antibody in many cases of primary systemic mast cell activation disease (MCAD). The present study should enable the clinician to recognize when treatment of MCAD with omalizumab is contraindicated because of the potential risk of severe serum sickness and to report our successful therapeutic strategy for such adverse event (AE). Our clinical observations, a review of the literature including the event reports in the FDA AE Reporting System, the European Medicines Agency Eudra-Vigilance databases (preferred search terms: omalizumab, Xolair®, and serum sickness) and information from the manufacturer's Novartis database were used. Omalizumab …

Whole Exome Sequencing In Patients With Williams-Beuren Syndrome Followed By Disease Modeling In Mice Points To Four Novel Pathways That May Modify Stenosis Risk, Phoebe C R Parrish, Delong Liu, Russell H Knutsen, Charles J Billington, Robert P Mecham, Yi-Ping Fu, Beth A Kozel

2020-Current year OA Pubs

Supravalvular aortic stenosis (SVAS) is a narrowing of the aorta caused by elastin (ELN) haploinsufficiency. SVAS severity varies among patients with Williams-Beuren syndrome (WBS), a rare disorder that removes one copy of ELN and 25-27 other genes. Twenty percent of children with WBS require one or more invasive and often risky procedures to correct the defect while 30% have no appreciable stenosis, despite sharing the same basic genetic lesion. There is no known medical therapy. Consequently, identifying genes that modify SVAS offers the potential for novel modifier-based therapeutics. To improve statistical power in our rare-disease cohort (N = 104 exomes), …

Systemic Inflammatory Response Syndrome In Patients With Acute Obstructive Upper Tract Urinary Stone: A Risk Factor For Urgent Renal Drainage And Revisit To The Emergency Department, Spencer Larkin, Jeremy Johnson, Trisha Venkatesh, Joel Vetter, Ramakrishna Venkatesh

Open Access Publications

BACKGROUND: In patients seen in the emergency department (ED) with acute stone obstruction many risk factors that indicate need for urgent renal drainage are known. However, in patients discharged from ED without renal drainage factors that can minimize revisit to the emergency department are not fully identified. We evaluated SIRS (systemic inflammatory response syndrome) as a risk factor for urgent renal drainage and revisit to the ED in patients with acute stone colic during their ED visit.

METHODS: Retrospective review was performed of patients presenting to a tertiary academic emergency department (ED) from an obstructing ureteral or UPJ stone with …

Coronary Heart Disease And Mortality Following A Breast Cancer Diagnosis, Aixia Guo, Kathleen W Zhang, Kristi Reynolds, Randi E Foraker

Open Access Publications

BACKGROUND: Coronary heart disease (CHD) is a leading cause of morbidity and mortality for breast cancer survivors, yet the joint effect of adverse cardiovascular health (CVH) and cardiotoxic cancer treatments on post-treatment CHD and death has not been quantified.

METHODS: We conducted statistical and machine learning approaches to evaluate 10-year risk of these outcomes among 1934 women diagnosed with breast cancer during 2006 and 2007. Overall CVH scores were classified as poor, intermediate, or ideal for 5 factors, smoking, body mass index, blood pressure, glucose/hemoglobin A1c, and cholesterol from clinical data within 5 years prior to the breast cancer diagnosis. …

Open Access Publications

BACKGROUND: Upper extremity musculoskeletal disorders (UEMSD) are one of the most common and costly occupational health problems. We aimed to assess the population-attributable fraction (PAF) of personal and occupational risk factors associated with incident UEMSD in a working population.

METHODS: From 2002 to 2005, a random sample of 3710 workers from the Pays de la Loire region in France, aged 20-59 were included by occupational physicians (OPs). Between 2007 and 2010, 1611 workers were re-examined by their OPs. Subjects free from UEMSD at baseline were included in this study (1275 workers, mean age: 38.2 years). Cox regression models with equal …

Personal, Biomechanical, Psychosocial, And Organizational Risk Factors For Carpal Tunnel Syndrome: A Structural Equation Modeling Approach, Yves Roquelaure, Ronan Garlantézec, Bradley A. Evanoff, Alexis Descatha, Jean-Baptiste Fassier, Julie Bodin

2020-Current year OA Pubs

This longitudinal study aimed at exploring the direct and indirect relationships between organizational, psychosocial, biomechanical, and personal factors and carpal tunnel syndrome (CTS) in French workers. Between 2002 and 2005, 3710 workers were included in the Cosali cohort. Between 2007 and 2010, 1611 workers were re-examined using the same standardized clinical protocol. Subjects free from CTS at baseline were studied (804 men and 563 women). We used structural equation models to examine the relationships between incident CTS cases and organizational (machine-paced work or work pace dependent on customers' demand), psychosocial (job strain model), biomechanical (Borg's rating perceived exertion, wrist bending, …

Deep Learning Assessment Of Breast Terminal Duct Lobular Unit Involution: Towards Automated Prediction Of Breast Cancer Risk, Suzanne C. Wetstein, Ying Liu, Et Al.

Open Access Publications

Terminal duct lobular unit (TDLU) involution is the regression of milk-producing structures in the breast. Women with less TDLU involution are more likely to develop breast cancer. A major bottleneck in studying TDLU involution in large cohort studies is the need for labor-intensive manual assessment of TDLUs. We developed a computational pathology solution to automatically capture TDLU involution measures. Whole slide images (WSIs) of benign breast biopsies were obtained from the Nurses' Health Study. A set of 92 WSIs was annotated for acini, TDLUs and adipose tissue to train deep convolutional neural network (CNN) models for detection of acini, and …
