Biventricular Myocardial Performance Is Impaired In Proportion To Severity Of Obstructive Sleep Apnea, Selahattin Akyol, Mustafa Cortuk, Ahmet Oytun Baykan, Kemal Kiraz, Abdurrezzak Borekci, Taner Seker, Mustafa Gur, Murat Cayli

The Texas Heart Institute Journal

Obstructive sleep apnea (OSA) is an independent risk factor for cardiovascular morbidity and death. Little information is available regarding the relationship between the severity of OSA and myocardial performance in OSA patients who have normal ejection fractions. We prospectively investigated this relationship, using the tissue-Doppler myocardial performance index (TD-MPI).

We conducted overnight, full-laboratory polysomnographic examinations of 116 patients, and calculated the left and right ventricular TD-MPIs. Patients were classified into 3 groups in accordance with their apnea-hypopnea index (AHI) levels: AHImild (≥5 to <15), AHImoderate (≥15 to <30), and AHIsevere (≥30).

Left and right ventricular TD-MPI values were higher in the AHIsevere group than in the AHImild and …

Comparison Of Interactive Voice Response (Ivr) With Paper Administration Of Instruments To Assess Functional Status, Sexual Function, And Quality Of Life In Elderly Men, Rc Rosen, Aj Stephens-Shields, Gr Cunningham, D Cifelli, D Cella, Jt Farrar, E Barrett-Connor, Ce Lewis, M Pahor, X Hou, Pj Snyder

Faculty, Staff and Students Publications

PURPOSE: Patient-reported outcome (PRO) measures are essential for assessing subjective patient experiences. Interactive voice response (IVR) data collection provides advantages for clinical trial design by standardizing and centralizing the assessment. Prior to adoption of IVR as a mode of PRO administration in the Testosterone Trials (TTrials), we compared IVR to paper versions of the instruments to be used. METHODS: IVR versions of the FACIT-Fatigue scale and Psychosexual Daily Questionnaire, Question 4, were developed. In one pilot study, IVR versions of these scales were compared to paper versions in 25 men = 65 years at each of two clinical sites. In …

Bioprosthetic Aortic Valve Endocarditis In Association With Enterococcus Durans, Luca Fallavollita, Lorena Di Gioacchino, Fabrizio Balestrini

The Texas Heart Institute Journal

Enterococci are common organisms associated with endocarditis, but infection by Enterococcus durans is very rare. To our knowledge, only 3 cases have been reported in the medical literature, and all 3 have involved native valves. Here we publish the first reported case (to our knowledge) of E. durans endocarditis in association with a bioprosthetic aortic valve. After the organism and its antibiotic susceptibility were identified, the 74-year-old male patient was treated successfully with teicoplanin and gentamicin, over a course of 6 weeks.

Cardiac Papillary Fibroelastoma: Single-Institution Experience With 14 Surgical Patients, Walid K Abu Saleh, Odeaa Al Jabbari, Basel Ramlawi, Michael J Reardon

The Texas Heart Institute Journal

In general, treatment for symptomatic and asymptomatic cardiac papillary fibroelastoma is surgical resection-particularly of left-sided lesions, because of the risk of systemic embolization. However, few institutions have enough experience with these tumors to validate this approach. We present our institutional experience with papillary fibroelastoma and discuss our current approach. We searched our institution's cardiac tumor database, identified all patients diagnosed with cardiac papillary fibroelastoma from 1992 through 2014, and recorded the clinical and pathologic characteristics of each case. We found 14 patients (mean age, 60.5 ± 12.3 yr) who had 18 lesions. Eleven patients (79%) were symptomatic; however, we could …

Longitudinal Changes In Vascular Risk Markers And Mortality Rates Among A Latino Population With Hypertension, Matthew C Pflederer, Carlin S Long, Brenda Beaty, Edward P Havranek, Philip S Mehler, Angela Keniston, Mori J Krantz

The Texas Heart Institute Journal

Vascular markers such as pulse-wave velocity and carotid intima-media thickness (CIMT) might improve the prediction of incident cardiovascular disease beyond traditional risk factors. These vascular markers have not been well characterized in minority populations and might be more useful than inflammatory biomarkers. We conducted a prospective, longitudinal cohort study among hypertensive patients in an urban safety-net hospital. We evaluated inflammatory biomarkers, arterial pulse-wave velocity, and carotid intima-media thickness at baseline, 1 year, and 2 years. The primary outcome variable was CIMT. Generalized linear mixed-effects models were used to evaluate associations between CIMT and predictive variables accounting for the correlation of …

Ct-Based Structural Rigidity Analysis Is More Accurate Than Mirels Scoring For Fracture Prediction In Metastatic Femoral Lesions, Ta Damron, A Nazarian, V Entezari, C Brown, W Grant, N Calderon, Et Al.

Faculty, Staff and Students Publications

BACKGROUND: Controversy continues regarding the appropriate assessment of fracture risk in long bone lesions affected by disseminated malignancy. QUESTIONS/PURPOSES: The purpose of this ongoing Musculoskeletal Tumor Society-sponsored, multi-institutional prospective cross-sectional clinical study is to compare CT-based structural rigidity analysis (CTRA) with physician-derived Mirels scoring for predicting pathologic fracture in femoral bone lesions. We hypothesized CTRA would be superior to Mirels in predicting fracture risk within the first year based on (1) sensitivity, specificity, positive predictive value, and negative predictive value; (2) receiver operator characteristic (ROC) analysis; and (3) fracture prediction after controlling for potential confounding variables such as age and …

Explicit Time Deficit In Schizophrenia: Systematic Review And Meta-Analysis Indicate It Is Primary And Not Domain Specific, V Ciullo, G Spalletta, C Caltagirone, Re Jorge, F Piras

Faculty, Staff and Students Publications

Although timing deficits are a robust finding in schizophrenia (SZ), the notion of a genuine time perception disorder in SZ is still being debated because distortions in timing might depend on neuropsychological deficits that are characteristics of the illness. Here we used meta-analytic methods to summarize the evidence of timing deficits in SZ and moderator analyses to determine whether defective timing in SZ arises from nontemporal sources or from defective time perception. PubMed Services, PsycNET, and Scopus were searched through March 2015, and all references in articles were investigated to find other relevant studies. Studies were selected if they included …

Genome Engineering: Drosophila Melanogaster And Beyond, Kjt Venken, A Sarrion-Perdigones, Pj Vandeventer, Ns Abel, Ae Christiansen, Kl Hoffman

Faculty, Staff and Students Publications

A central challenge in investigating biological phenomena is the development of techniques to modify genomic DNA with nucleotide precision that can be transmitted through the germ line. Recent years have brought a boon in these technologies, now collectively known as genome engineering. Defined genomic manipulations at the nucleotide level enable a variety of reverse engineering paradigms, providing new opportunities to interrogate diverse biological functions. These genetic modifications include controlled removal, insertion, and substitution of genetic fragments, both small and large. Small fragments up to a few kilobases (e.g., single nucleotide mutations, small deletions, or gene tagging at single or multiple …

Identification Of An Association Of Tnfaip3 Polymorphisms With Matrix Metalloproteinase Expression In Fibroblasts In An Integrative Study Of Systemic Sclerosis-Associated Genetic And Environmental Factors*, Peng Wei, Yang Yang, Xinjian Guo, Nainan Hei, Syeling Lai, Shervin Assassi, Mengyuan Liu, Filemon Tan, Xiaodong Zhou

Faculty, Staff and Students Publications

OBJECTIVE: Systemic sclerosis (SSc) is a fibrotic disease attributed to both genetic susceptibility and environmental factors. This study was undertaken to investigate the associations between SSc-associated genetic variants and the expression of extracellular matrix (ECM) genes in human fibroblasts stimulated with silica particles in time-course and dose-response experiments.

METHODS: A total of 200 fibroblast strains were examined for ECM gene expression after stimulation with silica particles. The fibroblasts were genetically profiled using Immunochip assays and then subjected to whole-genome genotype imputation. Associations of genotypes and gene expression were first analyzed in a Caucasian cohort and then validated in a meta-analysis …

Faculty, Staff and Students Publications

BACKGROUND: It has been anticipated that physician and parents will be ill prepared or unprepared for the clinical introduction of genome sequencing, making it ethically disruptive.

PROCEDURE: As a part of the Baylor Advancing Sequencing in Childhood Cancer Care study, we conducted semistructured interviews with 16 pediatric oncologists and 40 parents of pediatric patients with cancer prior to the return of sequencing results. We elicited expectations and attitudes concerning the impact of sequencing on clinical decision making, clinical utility, and treatment expectations from both groups. Using accepted methods of qualitative research to analyze interview transcripts, we completed a thematic analysis …

Early Rescue Of Interneuron Disease Trajectory In Developmental Epilepsies, Ms Siehr, Jl Noebels

Faculty, Staff and Students Publications

The discovery of over 150 monogenic epilepsies and advances in early genetic diagnoses have launched a search for molecular strategies and developmental timetables to reverse or even prevent the course of these debilitating brain disorders. Orthologous rodent models of key disease genes are providing important examples of the range of targets, and serve as valuable test systems for perinatal therapeutic approaches. While gene-specific analyses of single rare 'orphan' diseases are each narrow in scope, they illuminate downstream pathways converging onto interneurons, and treatments that strengthen inhibition during cortical maturation may provide broad protection against these seemingly disparate gene errors. Several …

Binomial Regression With A Misclassified Covariate And Outcome, Sheng Luo, Wenyaw Chan, Michelle A Detry, Paul J Massman, R S. Doody

Faculty, Staff and Students Publications

Misclassification occurring in either outcome variables or categorical covariates or both is a common issue in medical science. It leads to biased results and distorted disease-exposure relationships. Moreover, it is often of clinical interest to obtain the estimates of sensitivity and specificity of some diagnostic methods even when neither gold standard nor prior knowledge about the parameters exists. We present a novel Bayesian approach in binomial regression when both the outcome variable and one binary covariate are subject to misclassification. Extensive simulation results under various scenarios and a real clinical example are given to illustrate the proposed approach. This approach …

Glial Contributions To Neural Function And Disease, Mn Rasband

Faculty, Staff and Students Publications

The nervous system consists of neurons and glial cells. Neurons generate and propagate electrical and chemical signals, whereas glia function mainly to modulate neuron function and signaling. Just as there are many different kinds of neurons with different roles, there are also many types of glia that perform diverse functions. For example, glia make myelin; modulate synapse formation, function, and elimination; regulate blood flow and metabolism; and maintain ionic and water homeostasis to name only a few. Although proteomic approaches have been used extensively to understand neurons, the same cannot be said for glia. Importantly, like neurons, glial cells have …

Alternative Surgical Approach To Repairing A Giant Sinus Of Valsalva Aneurysm, Vincenzo Giambruno, Cristina Cucchietti, Calogera Pisano, Jonathan Hyde

The Texas Heart Institute Journal

We report our method of surgically repairing an unruptured giant aneurysm of the right coronary sinus of Valsalva, a lesion that caused moderate aortic regurgitation but no symptoms in a 61-year-old woman. We excised the aneurysm, reconstructed the right sinus of Valsalva with use of a patch, performed mechanical aortic valve replacement directly through the excised aneurysm's cavity, and constructed a single bypass graft to the right coronary artery. The patient was discharged from the hospital after 5 days. Twelve months postoperatively, her clinical and echocardiographic results were normal, and she was doing well. To our knowledge, our surgical approach …

Aortic Dissection Caused By Percutaneous Coronary Intervention: 2 New Case Reports And Detailed Analysis Of 86 Previous Cases, Priyank Shah, Sharad Bajaj, Fayez Shamoon

The Texas Heart Institute Journal

Aortic dissection, a rare sequela of percutaneous coronary intervention, can be fatal when it is not recognized and treated promptly. Treatment varies from conservative management to invasive aortic repair and revascularization. We report the cases of 2 patients whose aortic dissection was caused by percutaneous coronary intervention. In addition, we present detailed analyses of 86 previously reported cases. Aortic dissection was most often seen during intervention to the right coronary artery (in 76.7% of instances). The 2 most frequently reported causes were catheter trauma (in 54% of cases) and balloon inflation (in 23.8%). The overall mortality rate was 7.1%. We …
