Papillary Fibroelastoma Incidentally Found On Left Atrial Wall During Minimally Invasive Aortic Valve Replacement, Qasim Al Abri, Lamees I El Nihum, M Mujeeb Zubair, Roberto Barrios, Michael J Reardon, Mahesh Ramchandani

The Texas Heart Institute Journal

A 60-year-old man was about to undergo minimally invasive aortic valve replacement when transesophageal echocardiography revealed an intracardiac mass on the left atrial free wall. Multimodal images from 5 months earlier had shown no mass. We converted the procedure to open surgery. The excised mass resembled a cardiac myxoma but was determined to be a papillary fibroelastoma. This case illustrates that papillary fibroelastomas can form and grow rapidly, warranting alertness for their unexpected discovery before and during cardiac surgical procedures.

Myocardial Scintigraphy In Diagnosing Cardiac Transthyretin Amyloidosis, Marija Petrovic, Persio D Lopez, Calvin Eng, Mahjabeen Rashid

The Texas Heart Institute Journal

Myocardial scintigraphy with technetium-99m pyrophosphate is a minimally invasive technique that can distinguish between transthyretin amyloidosis (ATTR) and light-chain amyloidosis. We present a case in which it helped determine the amyloidosis type in a 74-year-old man with cardiac amyloidosis and multiple previous admissions for acute decompensated heart failure. The patient presented with increasing abdominal girth and bilateral lower extremity edema. His medical history also included atrial fibrillation, liver cirrhosis, hypertension, stage 3 chronic kidney disease, and peripheral vascular disease. We prescribed guideline-directed medical therapy for his acute decompensated heart failure with cardiorenal syndrome and his decompensated cirrhosis. Two years previously, …

Mitral Regurgitation And Serum N-Terminal Pro-Brain Natriuretic Peptide Levels In Children: A Modification Of Adult Criteria, Elif Erolu, Figen Akalin

The Texas Heart Institute Journal

Mitral regurgitation can result from congenital heart disease, rheumatic valve disease, or other congenital malformations of the mitral valve. Faulty valves require surgical repair or replacement. However, echocardiographic and biochemical parameters that inform surgical decision-making for adults may not be appropriate for children. To investigate whether adult parameters can be used in children, we correlated echocardiographic parameters with serum N-terminal pro-brain natriuretic peptide (NT-proBNP) levels in children with chronic mitral regurgitation.

Our sample comprised 45 patients and 38 healthy children. M-mode measurements, left atrial and left ventricular volumes, and Doppler and tissue Doppler echocardiograms were collected. We graded mitral regurgitation …

Successful elimination of bacteria in phagocytes occurs in the phago-lysosomal system, but also depends on mitochondrial pathways. Yet, how these two organelle systems communicate is largely unknown. Here we identify the lysosomal biogenesis factor transcription factor EB (TFEB) as regulator for phago-lysosome-mitochondria crosstalk in macrophages. By combining cellular imaging and metabolic profiling, we find that TFEB activation, in response to bacterial stimuli, promotes the transcription of aconitate decarboxylase (Acod1, Irg1) and synthesis of its product itaconate, a mitochondrial metabolite with antimicrobial activity. Activation of the TFEB-Irg1-itaconate signalling axis reduces the survival of the intravacuolar pathogen Salmonella enterica serovar Typhimurium. TFEB-driven …

The Role Of An Inpatient Hospice And Palliative Clinical Pharmacist In The Interdisciplinary Team, Jetavia Jones Moody, Ivy O Poon, Ursula K Braun

Center for Medical Ethics and Health Policy Staff Publications

Palliative care is a specialized health care service for individuals with serious illness at any stage and can be provided in any setting. Current national consensus developed by palliative care experts recommends the inclusion of pharmacists in an interdisciplinary team (IDT) to provide quality palliative care. However, national registry data report that less than 10% of inpatient palliative teams in the U.S. have a clinical pharmacist. Clinical pharmacists have an impactful role in palliative patients' quality of life by optimizing symptom management, deprescribing, and providing education to the palliative care team as well as patients and their families. In this …

White-Sutton syndrome (WHSUS), which is caused by heterozygous pathogenic variants in POGZ, is characterized by a spectrum of intellectual disabilities and global developmental delay with or without features of autism spectrum disorder. Additional features may include hypotonia, behavioral abnormalities, ophthalmic abnormalities, hearing loss, sleep apnea, microcephaly, dysmorphic facial features, and rarely, congenital diaphragmatic hernia (CDH). We present a 6-year-old female with features of WHSUS, including CDH, but with nondiagnostic clinical trio exome sequencing. Exome sequencing reanalysis revealed a heterozygous, de novo, intronic variant in POGZ (NM_015100.3:c.2546-20T>A). RNA sequencing revealed that this intronic variant leads to skipping of exon 18. …

Center for Medical Ethics and Health Policy Staff Publications

Somatic copy number alterations (SCNAs) in tumors are clinically significant diagnostic, prognostic, and predictive biomarkers. SCNA detection from targeted next-generation sequencing panels is increasingly common in clinical practice; however, detailed descriptions of optimization and validation of SCNA pipelines for small targeted panels are limited. This study describes the validation and implementation of a tumor-only SCNA pipeline using CNVkit, augmented with custom modules and optimized for clinical implementation by testing reference materials and clinical tumor samples with different classes of copy number variation (CNV; amplification, single copy loss, and biallelic loss). Using wet-bench and in silico methods, various parameters impacting CNV …

Provider Perceptions Of Telehealth And In-Person Exposure And Response Prevention For Obsessive-Compulsive Disorder, Andrew D Wiese, Kendall N Drummond, Madeleine N Fuselier, Jessica C Sheu, Gary Liu, Andrew G Guzick, Wayne K Goodman, Eric A Storch

Center for Medical Ethics and Health Policy Staff Publications

Until recently, psychotherapies, including exposure and response prevention (ERP) for obsessive-compulsive disorder (OCD), have primarily been delivered in-person. The COVID-19 pandemic required OCD providers delivering ERP to quickly transition to telehealth services. While evidence supports telehealth ERP delivery, limited research has examined OCD provider perceptions about patient characteristics that are most appropriate for this modality, as well as provider abilities to identify and address factors interfering with effective telehealth ERP. In the present study, OCD therapists (N = 113) rated the feasibility of delivering telehealth ERP relative to in-person for different (1) patient age-groups, (2) levels of OCD severity, and …

Color Characterization Of Color Changing Orthodontic Adhesives, Megan Fried

Master's Theses (2009 -)

Objective:A popular product to facilitate removal of excess adhesive during bonding of orthodontic appliances is a color changing adhesive. Before polymerization, these materials are a bright color but upon curing, manufacturers claim they become translucent. After debonding, there is often resin embedded within the enamel, so the appearance of these materials after polymerization can affect the esthetics of a patient’s dentition. The purpose of this study was to analyze the color characteristics of various orthodontic color changing adhesives and determine if there is a significant difference in color changing capabilities and in translucency after polymerization between products. Methods:Grengloo and Blugloo …

Autoignition And Sooting Characteristics Of Iso-Octane And Ethanol In An Optical Rapid Compression Machine, Richard John Kempf

Master's Theses (2009 -)

To effectively reduce particulate emissions and maximize the effectiveness of renewable fuels entering the industrial and transportation markets, an accurate understanding of the combustion characteristics of these fuels is a necessary undertaking. Typical engines used in the heavy-duty engine industry primarily rely on mixing-controlled combustion, which has the potential to produce soot under locally rich combustion conditions. A rapid compression machine (RCM) is an experimental reaction vessel used to investigate the ignition and pollutant behaviors of fuels at compressed conditions relevant to engine studies. In this study, an RCM has been prepared with line-of-sight optical accessibility such that a laser …

Mediating Effects Of Neighborhood-Level Socioeconomic Deprivation On The Association Between Race/Ethnicity And Advanced Hepatocellular Carcinoma, Abiodun O Oluyomi, Kusha A Mohammadi, Hashem B El-Serag, Aaron P Thrift

Faculty, Staff and Students Publications

BACKGROUND: Racial/ethnic minorities are more likely than non-Hispanic whites (NHW) to be diagnosed with advanced stage hepatocellular carcinoma (HCC). We examined the role of neighborhood disadvantage as a mediator of the association between race/ethnicity and HCC stage at diagnosis.

METHODS: We used data from HCC cases diagnosed in Texas from 2007 to 2015. HCC cases were classified as local versus regional/advanced stage. A mediation model approach was used to estimate the average direct effect, average mediated (indirect) effect, total effect, and proportion mediated by the Area Deprivation Index (ADI), a composite measure of disadvantage.

RESULTS: 7,622 had local while 6303 …

Faculty, Staff and Students Publications

COVID-19 morbidity and mortality are driven by poor immune regulation. Narrowband ultraviolet B (NB-UVB) phototherapy is standard of care in a number of immune-dysregulated diseases. To assess the efficacy of NB-UVB phototherapy for improving COVID-19 outcomes in high-risk, hospitalized, we developed the Adaptive Photo-Protection Trial. This is a multi-center, prospective, double-blinded, randomized, placebo-controlled trial. The pilot phase results are reported here. Consecutive patients admitted with a positive COVID-19 PCR were screened for eligibility. Enrolled subjects were computer randomized 1:1 to NB-UVB or placebo phototherapy. Subjects were treated daily with escalating doses on 27% of their body surface area for up …

BACKGROUND: Tuberculosis remains a leading cause of global mortality, especially for adults and children living with HIV (CLHIV) underdiagnosed by sputum-based assays. Non-sputum-based assays are needed to improve tuberculosis diagnosis and tuberculosis treatment monitoring. Our aim in this study was to determine whether ultrasensitive detection of Mycobacterium tuberculosis cell-free DNA (Mtb-cfDNA) in blood can diagnose tuberculosis and evaluate tuberculosis treatment responses.

METHODS: In this molecular diagnostics study we analysed archived serum from two patient populations evaluated for tuberculosis in Eswatini and Kenya to detect Mtb-cfDNA, analysing serum from all individuals who had both sufficient serum volumes and clear diagnostic results. …

A Practical Focus On Milk Oral Immunotherapy, Aikaterini Anagnostou

Faculty, Staff and Students Publications

Cow's milk allergy (CMA) is a common childhood food allergy associated with a significant burden for those children who are affected and their families, including unintentional exposures that result in allergic reactions, severe allergic reactions, and anaphylaxis. In young children, cow's milk is one of the most frequent food triggers in anaphylactic episodes, and fatalities have also been described as a result of unintentional exposures, which reinforces the notion that milk allergy can be severe in some individuals. The natural history of CMA is favorable, with the allergy resolving over time in the majority of individuals, although some will have …

Adipose tissue is a promising target for treating obesity and metabolic diseases. However, pharmacological agents usually fail to effectively engage adipocytes due to their extraordinarily large size and insufficient vascularization, especially in obese subjects. We have previously shown that during cold exposure, connexin43 (Cx43) gap junctions are induced and activated to connect neighboring adipocytes to share limited sympathetic neuronal input amongst multiple cells. We reason the same mechanism may be leveraged to improve the efficacy of various pharmacological agents that target adipose tissue. Using an adipose tissue-specific Cx43 overexpression mouse model, we demonstrate effectiveness in connecting adipocytes to augment metabolic …

Cutaneous squamous cell carcinoma (cSCC) comprises 15‒20% of all skin cancers and has a well-defined progression sequence from precancerous actinic keratosis to invasive cSCC. To identify targets for chemoprevention, we previously reported a cross-species analysis to identify the transcriptional drivers of cSCC development and identified miR-181a as a potential oncomiR. We show that the upregulation of miR-181a promotes multiple protumorigenic properties by targeting an understudied component of TGFβ signaling, TGFβR3. miR-181a and TGFβR3 are upregulated and downregulated, respectively, in cSCC. miR-181a overexpression (OE) and TGFβR3 knockdown (KD) significantly suppresses UV-induced apoptosis in HaCaT cells and in primary normal human epidermal …

Faculty, Staff and Students Publications

INTRODUCTION: Mutations in the LMNA gene, encoding Lamin A/C (LMNA), are established causes of dilated cardiomyopathy (DCM). The phenotype is typically characterized by progressive cardiac conduction defects, arrhythmias, heart failure, and premature death. DCM is primarily considered a disease of cardiac myocytes. However, LMNA is also expressed in other cardiac cell types, including fibroblasts.

AIM: The purpose of the study was to determine the contribution of the fibroblasts to DCM caused by LMNA deficiency.

METHODS AND RESULTS: The Lmna gene was deleted by crossing the platelet-derived growth factor receptor α-Cre recombinase (Pdgfra-Cre) and floxed Lmna (LmnaF/F) …

Prediction Of Patient Outcomes Through Social Determinants Of Health: The Pulmonary Hypertension Association Registry (Phar) Evaluation, Dan Grinnan, Murali Chakinala, Et Al.

2020-Current year OA Pubs

Outcomes of patients with pulmonary arterial hypertension (PAH) may be associated with social determinants of health (SDOH) and other baseline patient characteristics. At present, there is no prognostic model to predict important patient outcomes in PAH based on SDOH. Utilizing information from the Pulmonary Hypertension Association Registry (PHAR), we derive a model (PHAR Evaluation or PHARE) to predict an important composite patient outcomes based on SDOH and other patient characteristics. Baseline data regarding SDOH from adult patients with PAH enrolled in the PHAR between 2015 and March 23, 2020, were included for analysis. We performed repeated measures logistic regression modeling …

BACKGROUND: The Infectious Diseases Society of America (IDSA) guidelines for the management of histoplasmosis were last revised 15 years ago. Since those guidelines were compiled, new antifungal treatment options have been developed. Furthermore, the ongoing development of immunomodulatory therapies has increased the population at increased risk to develop histoplasmosis.

METHODS: An electronic survey about the management practices of histoplasmosis was distributed to the adult infectious disease (ID) physician members of the IDSA's Emerging Infections Network.

RESULTS: The survey response rate was 37% (551/1477). Only 46% (253/551) of respondents reported seeing patients with histoplasmosis. Regions considered endemic had 82% (158/193) of …

The molecular events responsible for decitabine responses in myelodysplastic syndrome and acute myeloid leukemia patients are poorly understood. Decitabine has a short serum half-life and limited stability in tissue culture. Therefore, theoretical pharmacologic differences may exist between patient molecular changes in vitro and the consequences of in vivo treatment. To systematically identify the global genomic and transcriptomic alterations induced by decitabine in vivo, we evaluated primary bone marrow samples that were collected during patient treatment and applied whole-genome bisulfite sequencing, RNA-sequencing, and single-cell RNA sequencing. Decitabine induced global, reversible hypomethylation after 10 days of therapy in all patients, which was …

Thrombocytopenia is common in patients with myelofibrosis (MF) and is a well-established adverse prognostic factor. Both of the approved Janus kinase (JAK) inhibitors, ruxolitinib and fedratinib, can worsen thrombocytopenia and have not been evaluated in patients with severe thrombocytopenia (platelet counts <50×109/L). Pacritinib, a novel JAK2/interleukin-1 receptor-associated kinase 1 inhibitor, has been studied in two phase III trials (PERSIST-1 and PERSIST- 2), both of which enrolled patients with MF and severe thrombocytopenia. In order to better characterize treatment outcomes for this population with advanced disease, we present a retrospective analysis of efficacy and safety data in the 189 patients with severe thrombocytopenia treated in the PERSIST studies. The proportion of patients in the pacritinib group meeting efficacy endpoints was greater than in the BAT group for ≥35% spleen volume reduction (23% vs. 2%, P=0.0007), ≥50% modified Total Symptom Score reduction (25% vs. 8%, P=0.044), and self-reported symptom benefit ("much" or "very much" improved; 25% vs. 8%, P=0.016) at the primary analysis time point (week 24). The adverse event profile of pacritinib was manageable, and dose modification was rarely required. There was no excess in bleeding or death in pacritinib-treated patients. These results indicate that pacritinib is a promising treatment for patients with MF who lack safe and effective therapeutic options due to severe thrombocytopenia.
