How Different Is Invasive Coronary Physiology In The Left Anterior Descending Artery?, Nils P Johnson, K Lance Gould

Faculty, Staff and Student Publications

Given the large amount of myocardium supplied by the left anterior descending (LAD) artery, it understandably receives additional scrutiny during coronary angiography. However, these same features make the interpretation of pressure wire physiology more nuanced to avoid overtreatment. This review provides case examples to underpin an extensive literature review supporting the argument that a "positive" fractional flow reserve (FFR) in the LAD needs to be approached with caution. A large hyperemic gradient, or low FFR, can arise from either a severe and focal lesion in conjunction with low flow or diffuse disease coupled with intact or normal flow. Separating these …

Changes In Medication Complexity And Post-Hospitalization Outcomes In Older Adults Hospitalized For Heart Failure, Aayush Visaria, William Mcdonald, John Mancini, Andrew P Ambrosy, Min Ji Kwak, Ashkan Hashemi, Mark S Lachs, Andrew R Zullo, Monika Safford, Emily B Levitan, Parag Goyal

Faculty, Staff and Student Publications

Introduction: Medication regimen complexity may be an important risk factor for adverse outcomes in older adults with heart failure. However, increasing complexity is often necessary when prescribing guideline-directed medical therapy at the time of a heart failure hospitalization. We sought to determine whether increased medication regimen complexity following a heart failure hospitalization was associated with worse post-hospitalization outcomes.

Methods: This retrospective cohort study included Reasons for Geographic and Racial Differences in Stroke (REGARDS) participants aged at least 65 years hospitalized for heart failure between 2003 and 2014. We calculated changes between hospital admission and discharge in medication count (Δcount) and …

Faculty, Staff and Student Publications

Exposure-based treatments such as prolonged exposure therapy (PE) are effective for veterans with PTSD. However, dropout rates as high as 50% are common. The Department of Veterans Affairs employs peers to increase mental health treatment engagement, however peers are not routinely used to help patients complete PE homework assignments. The present study included 109 veterans who decided to drop out from exposure-based treatment after completing seven or fewer sessions and used a randomized controlled design to compare PE treatment completion rates in response to 2 forms of peer support: (1) standard weekly telephone-based peer support vs. (2) peer-assisted in vivo …

Exploring The Role Of Reward Functioning In The Overlap Of Post-Traumatic Stress And Cocaine Use Disorder, Kate Hull, Hanaan Bing-Canar, Krista Miloslavich, Christopher Holden, Aneet Ahluwalia, Scott D Lane, Joy M Schmitz, Margaret C Wardle

Faculty, Staff and Student Publications

Background: Posttraumatic stress disorder (PTSD) symptoms are common in people with cocaine use disorder (CUD), and even sub-threshold PSTD symptoms result in worse treatment outcomes. Difficulties with reward functioning may drive this comorbidity. Impairments in reward functioning are prominent in both PTSD and CUD and contribute to development of substance use problems after trauma. There are three distinct reward processes that may be involved in the PTSD/CUD overlap: consummatory reward (ability to experience pleasure), motivational reward (willingness to exert effort for rewards), and reward learning (adapting behavior based on reward history). Here we test whether impairments in these reward functions …

The accumulation of amyloid plaques and neurofibrillary tangles are pathological hallmarks of Alzheimer's disease (AD). While amyloid-beta propagation through prion-like mechanisms has been extensively studied in both central and peripheral pathways, the potential spreading of tau aggregates in the periphery remains largely unexplored. Emerging evidence suggests that hyperphosphorylated tau (ptau) aggregates may propagate beyond the central nervous system, as they have been detected in peripheral tissues and biological fluids from humans and mouse models of tauopathies. However, whether peripheral ptau aggregates or other factors associated to its accumulation contribute to brain pathology remains unclear. In this study, we investigate the …

Wnt7a, Naomi M Calhoun, Richard R Behringer

Faculty, Staff and Student Publications

WNT7A regulates numerous developmental processes. It can activate canonical and non-canonical signaling depending on context. It is expressed in the developing central nervous system, limb buds, reproductive organs, and other tissues. Spontaneous and targeted Wnt7a mutations in mouse models resulted in abnormal limbs, defects in male and female reproductive tract organs, infertility, and defects in cerebellar axon remodeling. In zebrafish, wnt7aa mutants exhibited neurogenesis and angiogenesis defects in the central nervous system. In humans, recessive WNT7A missense and nonsense mutations resulted in severe limb and pelvic bone defects. Alterations in WNT7A expression correlated with multiple types of cancer.

Effective Thrombectomy For Biventricular Thrombosis With An Endoscope Via The Aortic And Tricuspid Heart Valves, Yuki Endo, Yoshiei Shimamura, Chizuo Kikuchi, Hiroshi Niinami

The Texas Heart Institute Journal

The simultaneous formation of thrombi in the left and right ventricles is extremely rare, and this condition's clinical characteristics and prognosis remain unknown. Therefore, treatment methods are still controversial. This case highlights the potential for endoscopic thrombectomy as a viable option for the treatment of giant floating biventricular thrombi in a patient with restricted cardiac function. This approach via the aortic and tricuspid heart valves allowed for effective and complete removal of the thrombi, thereby preventing further embolic complications.

Igf-1 Impacts Neocortical Interneuron Connectivity In Epileptic Spasm Generation And Resolution, Carlos J Ballester-Rosado, John T Le, Trang T Lam, Anne E Anderson, James D Frost, John W Swann

Faculty, Staff and Students Publications

Little is known about the mechanisms that generate epileptic spasms following perinatal brain injury. Recent studies have implicated reduced levels of Insulin-like Growth Factor 1 (IGF-1) in these patients' brains. Other studies have reported low levels of the inhibitory neurotransmitter, GABA. In the TTX brain injury model of epileptic spasms, we undertook experiments to evaluate the impact of IGF-1 deficiencies on neocortical interneurons and their role in spasms. Quantitative immunohistochemical analyses revealed that neocortical interneurons that express glutamic acid decarboxylase, parvalbumin, or synaptotagmin 2 co-express IGF-1. In epileptic rats, expression of these three interneuron markers were reduced in the neocortex. …
