Convexity Dural Hemangioma: Illustrative Case, Ellery A. Hayden, Jack A. Leoni, Frank Culicchia
Convexity Dural Hemangioma: Illustrative Case, Ellery A. Hayden, Jack A. Leoni, Frank Culicchia
School of Medicine Faculty Publications
BACKGROUND: Dural hemangiomas are a relatively rare form of intracranial mass, as hemangiomas tend to present in bone or as intraparenchymal lesions and only around 5%-13% have been reported to originate from the dura mater. Here, the authors present the case of a 46-year-old female who underwent craniotomy for a suspected convexity meningioma resection, which was unexpectedly found to be a dural capillary hemangioma. OBSERVATIONS: The patient was a 46-year-old female who presented with a left frontal intracranial mass found incidentally and showed significant growth over 4 years. The mass was suspected to be a meningioma as it was homogeneously …

OBJECTIVE: To evaluate the association of changes in peripartum blood pressure (BP) with risk for postpartum readmission for hypertension. METHODS: We conducted a retrospective cohort study of birthing individuals delivering from January 1, 2017, to March 1, 2020, in Louisiana. We identified patients with postpartum readmission for hypertension (readmission within 30 days of delivery) and compared BP and clinical and sociodemographic characteristics with those of patients who were not readmitted for hypertension. Patients were also grouped by their BP at both admission for delivery and 36 hours postpartum: systolic below 130 mm Hg and diastolic below 80 mm Hg, systolic …

IMPORTANCE: In-hospital cardiac arrest (IHCA) is a significant public health burden. Rates of return of spontaneous circulation (ROSC) have been improving, but the best way to care for patients after the initial resuscitation remains poorly understood, and improvements in survival to discharge are stagnant. Existing North American cardiac arrest databases lack comprehensive data on the post-resuscitation period, and we do not know current post-IHCA practice patterns. To address this gap, we developed the Discover In-Hospital Cardiac Arrest (Discover IHCA) study, which will thoroughly evaluate current post-IHCA care practices across a diverse cohort. OBJECTIVES: Our study collects granular data on post-IHCA …

Cardiovascular disease (CVD) stands as one of the leading causes of morbidity and mortality worldwide, and the continued search for novel therapeutics is vital for addressing this global health challenge. Over the past decade, hydrogen sulfide (H₂S) has garnered significant attention in the field of medical research, as it has been proven to be a cardioprotective gaseous signaling molecule. It joins nitric oxide and carbon monoxide as endogenously produced gasotransmitters. As for its mechanism, H₂S functions through the posttranslational addition of a sulfur group to cysteine residues on target proteins in a process called sulfhydration. As a result, the observed …

Hypertension is attributable long-term to various negative health outcomes, including atherosclerotic cardiovascular disease and, more broadly, to cardiovascular events such as congestive heart disease, myocardial infarction, heart failure, and stroke. Effective hypertension treatment is essential to lower the risk of these outcomes. Treatment of hypertension includes both nonpharmacologic and, if necessary, pharmacologic interventions. The drug classes proven in trials to decrease the risk of cardiovascular disease events in cases with hypertension include angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, thiazide diuretics, and calcium channel blockers. When considering thiazide diuretics as a first-line treatment, chlorthalidone (CTD) is currently recommended by the American …

School of Medicine Faculty Publications
A 63-year-old male developed a mycotic pseudoaneurysm (MPA) two months after a renal transplant at the anastomotic site. He presented with uncontrolled hypertension and elevated creatinine. The pseudoaneurysm occurred at the anastomosis between the two donor renal arteries and the left external iliac artery. We describe a unique surgical reconstruction where the MPA was resected and the vasculature was reconstructed using deceased donor vessels. A deceased donor common iliac artery including superior gluteal and inferior gluteal branches were used as a jump graft from the contralateral common iliac artery to the two transplanted renal arteries. The external iliac artery was …

BACKGROUND: Pulmonary hypertension (PH) is a leading cause of death in patients with systemic sclerosis (SSc). An important component of SSc patient management is early detection and treatment of PH. Recently the threshold for the diagnosis of PH has been lowered to a mean pulmonary artery pressure (mPAP) threshold of > 20 mmHg on right heart catheterization (RHC). However, it is unknown if PH-specific therapy is beneficial in SSc patients with mildly elevated pressure (SSc-MEP, mPAP 21-24 mmHg). METHODS: The SEPVADIS trial is a randomized, double-blind, placebo-controlled phase 2 trial of sildenafil in SSc-MEP patients with a target enrollment of 30 …

The treatment of severe aortic stenosis (SAS) has evolved rapidly with the advent of minimally invasive structural heart interventions. Transcatheter aortic valve replacement has allowed patients to undergo definitive SAS treatment achieving faster recovery rates compared to valve surgery. Not infrequently, patients are admitted/diagnosed with SAS after a fall associated with a hip fracture (HFx). While urgent orthopedic surgery is key to reduce disability and mortality, untreated SAS increases the perioperative risk and precludes physical recovery. There is no consensus on what the best strategy is either hip correction under hemodynamic monitoring followed by valve replacement or preoperative balloon aortic …

Obstructive sleep apnea (OSA) is associated with ischemic stroke. There is, however, a lack of knowledge on the exact cause-effect relationship, and preclinical models of OSA for experimental ischemic stroke investigations are not well characterized. In this review, we discuss sleep apnea and its relationship with stroke risk factors. We consider how OSA may lead to ischemic stroke and how OSA-induced metabolic syndrome and hypothalamic-pituitary axis (HPA) dysfunction could serve as therapeutic targets to prevent ischemic stroke. Further, we examine the translational potential of established preclinical models of OSA. We conclude that metabolic syndrome and HPA dysfunction, which are often …

BACKGROUND: Female sex is a significant risk factor for pulmonary arterial hypertension (PAH), yet males with PAH have worse survival - a phenomenon referred to as the "sex paradox" in PAH. METHODS: All adult PAH patients in the Pulmonary Hypertension Association Registry (PHAR) with congruent sex and gender were included. Baseline differences in demographics, hemodynamics, functional parameters, and quality of life were assessed by sex. Kaplan-Meier survival analysis was used to evaluate survival by sex. Mediation analysis was conducted with Cox proportional hazards regression by comparing the unadjusted hazard ratios for sex before and after adjustment for covariates. The plausibility …

Alt Free Flap Coverage After Carotid Endarterectomy In The Setting Of Severe Radiation Changes, Richard F. Guidry, Hannah E. Doran, Mark W. Stalder
Alt Free Flap Coverage After Carotid Endarterectomy In The Setting Of Severe Radiation Changes, Richard F. Guidry, Hannah E. Doran, Mark W. Stalder
School of Medicine Faculty Publications
Carotid endarterectomy with patch angioplasty is commonly performed for severe atherosclerotic disease to reduce stroke risk. After neck radiation, loss of tissue planes; reactive fibrosis of skin; contraction; and rarely, necrosis of skin may occur, leading to severe wound complications and possible exposure of carotid artery reconstruction. Historically, local myocutaneous flaps have been performed to provide soft tissue coverage; however, these procedures may be associated with increased donor site morbidity and can be affected by radiation changes. This report describes the novel use of a fasciocutaneous free flap for durable vascularized soft tissue, and the associated secondary benefit of improved …

Alcohol-induced cardiomyopathy (ACM) has a poor prognosis with up to a 50% chance of death within four years of diagnosis. There are limited studies investigating the potential of abstinence for promoting repair after alcohol-induced cardiac damage, particularly in a controlled preclinical study design. Here, we developed an exposure protocol that led to significant decreases in cardiac function in C57BL6/J mice within 30 days; dP/dt max decreased in the mice fed alcohol for 30 days (8054 ± 664.5 mmHg/s compared to control mice: 11,188 ± 724.2 mmHg/s, p < 0.01), and the dP/dt min decreased, as well (−7711 ± 561 mmHg/s compared to control mice: −10,147 ± 448.2 mmHg/s, p < 0.01). Quantitative PCR was used to investigate inflammatory and fibrotic biomarkers, while histology was used to depict overt changes in cardiac fibrosis. We observed a complete recovery of function after abstinence (dP/dt max increased from 8054 ± 664 mmHg/s at 30 days to 11,967 ± 449 mmHg/s after abstinence, p < 0.01); further, both inflammatory and fibrotic biomarkers decreased after abstinence. These results lay the groundwork for future investigation of the molecular mechanisms underlying recovery from alcohol-induced damage in the heart.

Superficial temporal artery pseudoaneurysms are an uncommon vascular pathology that can present after head or facial trauma. Furthermore, they are rarely reported in the pediatric population. Ultrasound can be a useful tool in the diagnosis because it is easily accessible and can be rapidly acquired. We report a case that demonstrates the utility of ultrasound in the diagnosis of a superficial temporal artery pseudoaneurysm.

Heart failure (HF) is a chronic and progressive clinical disorder characterized by an inability to pump sufficient blood to meet metabolic demands. It poses a substantial global healthcare burden, leading to high morbidity, mortality, and economic impact. Current treatments for HF include lifestyle modifications, guideline-directed medical therapies (GDMT), and device interventions, but the need for novel therapeutic approaches remains significant. The introduction of vericiguat, a soluble guanylate cyclase stimulator, has shown promise in improving outcomes for heart failure patients. Vericiguat addresses the underlying pathophysiological mechanisms of heart failure by augmenting the cyclic guanosine monophosphate (cGMP) pathway, leading to enhanced cardiac …

Left Juxtaposition Of The Right Atrial Appendage: Pitfalls In Diagnosis, Kanya Singhapakdi, Wesam Sourour, Thomas Kimball
School of Medicine Faculty Publications
Several congenital anomalies of the right atrial appendage (RAA) have been described including aneurysm, herniation (in association with a pericardial defect), and left juxtaposition. The left juxtaposition of the RAA (LJRAA), first described by Birmingham in 1893 and subsequently introduced by Dixon in 1954, is usually associated with complex cardiac malformations such as obstruction of the left ventricular outflow tract. In this case report, we will describe an unusual variant of LJRAA in the absence of any other cardiac defects, which was initially misinterpreted as an aortic dissection. The correct diagnosis was made after careful reinterpretation and the use of …

Despite efforts to identify modulatory neuroprotective mechanisms of damaging ischemic stroke cascade signaling, a void remains on an effective potential therapeutic. The present study defines neuroprotection by very long-chain polyunsaturated fatty acid (VLC-PUFA) Elovanoid (ELV) precursors C-32:6 and C-34:6 delivered intranasally following experimental ischemic stroke. We demonstrate that these precursors improved neurological deficit, decreased T2WI lesion volume, and increased SMI-71 positive blood vessels and NeuN positive neurons, indicating blood–brain barrier (BBB) protection and neurogenesis modulated by the free fatty acids (FFAs) C-32:6 and C-34:6. Gene expression revealed increased anti-inflammatory and pro-homeostatic genes and decreases in expression of pro-inflammatory genes in …

Peripheral Arterial Disease And Complications Of Total Knee Arthroplasty: Indications For Advanced Vascular Imaging And Minimally Invasive Soft Tissue Coverage Procedures, Kristopher Katira, Antony Martin, Anna Garbuzov, James Ferrer, Brian Chuong, Ross Parkerson, George Chimento
School of Medicine Faculty Publications
Soft tissue coverage of knee wounds can be challenging, in particular in the setting of peripheral arterial disease and knee arthroplasty complications. Options for soft-tissue coverage range from conservative wound care to invasive pedicled and free flaps. Unlike traditional wound coverage problems in plastic surgery patients, arthroplasty coverage decisions oblige surgeons to take into account the possibility of secondary orthopedic procedures. The two cases presented in this manuscript demonstrate the importance of vascular imaging, in particular angiography. In both cases, the workhorse medial gastrocnemius flap harvest could have resulted in critical limb ischemia. When secondary orthopedic revision is required at …

Background: Tyrosine kinase inhibitors (TKIs) that specifically target mutational points in the EGFR gene have significantly reduced suffering and provided greater relief to patients with lung adenocarcinoma (LUAD). The third-generation EGFR-TKI, Osimertinib, has been successfully employed in clinical treatments to overcome resistance to both original and acquired T790M and L858R mutational points. Nevertheless, the issue of treatment failure response has emerged as an insurmountable problem. Methods: By employing a combination of multiple and integrated approaches, we successfully identified a distinct population within the tumor group that plays a significant role in carcinogenesis, resistance, and recurrence. Our research suggests that addressing …
Systemic Review Of Clot Retraction Modulators, Alaina Guilbeau, Rinku Majumder
Systemic Review Of Clot Retraction Modulators, Alaina Guilbeau, Rinku Majumder
School of Graduate Studies Faculty Publications
Through a process termed clot retraction, platelets cause thrombi to shrink and become more stable. After platelets are activated via inside-out signaling, glycoprotein αIIbβIII binds to fibrinogen and initiates a cascade of intracellular signaling that ends in actin remodeling, which causes the platelet to change its shape. Clot retraction is also important for wound healing. Although the detailed molecular biology of clot retraction is only partially understood, various substances and physiological conditions modulate clot retraction. In this review, we describe some of the current literature pertaining to clot retraction modulators. In addition, we discuss compounds from Cudrania trucuspidata, Arctium lappa, …

Our objective was to examine serum ferritin trends after conversion to permanent vascular access (PVA) among children who started hemodialysis (HD) using tunneled cuffed catheters (TCC). Retrospective chart reviews were completed on 98 subjects from 20 pediatric HD centers. Serum ferritin levels were collected at the creation of PVA and for two years thereafter. There were 11 (11%) arteriovenous grafts (AVG) and 87 (89%) arteriovenous fistulae (AVF). Their mean TCC use was 10.4 ± 17.3 months. Serum ferritin at PVA creation was elevated at 562.64 ± 492.34 ng/mL, increased to 753.84 ± 561.54 ng/mL (p = < 0.001) in the first year and remained at 759.60 ± 528.11 ng/mL in the second year (p = 0.004). The serum ferritin levels did not show a statistically significant linear association with respective serum hematocrit values. In a multiple linear regression model, there were three predictors of serum ferritin during the first year of follow-up: steroid-resistant nephrotic syndrome as primary etiology (p = 0.035), being from a center that enrolled >10 cases (p = …

Introduction Aneurysmal subarachnoid hemorrhage (aSAH) is a rare event associated with significant pregnancy-associated maternal and neonatal morbidity and mortality. The optimal treatment strategy and clinical outcome of aSAH in pregnancy remains unclear. We aimed to investigate the treatment utilizations and outcomes of aSAH in pregnant people. Methods Using the 2010-2018 National Inpatient Sample, we identified all birth hospitalizations of women between ages of 18 to 45 associated with subarachnoid hemorrhage and aneurysm treatment were included. Multivariate analyses were used to evaluate the effect of pregnancy state, mode of treatment of aneurysms, severity of subarachnoid hemorrhage on mortality and discharge destination …
