BACKGROUND: Trials aimed at preventing cognitive decline through cognitive stimulation among those with normal cognition or mild cognitive impairment are of significant importance in delaying the onset of dementia and reducing dementia prevalence. One challenge in these prevention trials is sample recruitment bias. Those willing to volunteer for these trials could be socially active, in relatively good health, and have high educational levels and cognitive function. These participants' characteristics could reduce the generalizability of study results and, more importantly, mask trial effects. We developed a randomized controlled trial to examine whether conversation-based cognitive stimulation delivered through personal computers, a webcam …

Recently, Sugihara proposed an innovative causality concept, which, in contrast to statistical predictability in Granger sense, characterizes underlying deterministic causation of the system. This work exploits Sugihara causality analysis to develop novel EEG biomarkers for discriminating normal aging from mild cognitive impairment (MCI) and early Alzheimer's disease (AD). The hypothesis of this work is that scalp EEG based causality measurements have different distributions for different cognitive groups and hence the causality measurements can be used to distinguish between NC, MCI, and AD participants. The current results are based on 30-channel resting EEG records from 48 age-matched participants (mean age 75.7 …

Over 100 trials show that patient decision aids effectively improve patients’ information comprehension and values-based decision making. However, gaps remain in our understanding of several fundamental and applied questions, particularly related to the design of interactive, personalized decision aids. This paper describes an interdisciplinary development process for, and early field testing of, a web-based patient decision support research platform, or virtual decision lab, to address these questions.

The Texas Heart Institute Journal
Transradial access is an alternative to the transfemoral approach in coronary interventions. It results in less access-site bleeding, shorter hospital stays, lower costs, and less pain for the patient. However, some authors have suggested that the transradial approach might lead to radial artery occlusion, which precludes repeated same-artery catheterizations. Using data from our center, we evaluated the feasibility, safety, and efficacy of repeated transradial catheterization.
We reviewed the 3,006 transradial catheterizations performed at our center from 2006 through 2009. Patients who had undergone at least one repeated transradial catheterization were identified, their cases monitored through 2012, and their baseline characteristics …

Brachiocephalic Artery Cannulation In Proximal Aortic Surgery That Requires Circulatory Arrest, Mehmet Unal, Oguz Yilmaz, Ilker Akar, Ilker Ince, Cemal Aslan, Fatih Koc, Haluk Kafali
The Texas Heart Institute Journal
The brachiocephalic artery is an alternative cannulation site in the repair of ascending aortic lesions that require circulatory arrest. We evaluate the effectiveness and safety of this technique.
Proximal aortic surgery was performed in 32 patients from 2006 through 2012 via brachiocephalic artery cannulation and circulatory arrest. Twenty-four (75%) of the patients were men. The mean age was 48.69 ± 9.43 years (range, 30–68 yr). Twelve had type I dissection, 2 had type II dissection, and 18 had true aneurysms of the ascending aorta. All operations were performed through a median sternotomy. The arterial cannula was inserted through an 8-mm …

Aortic Valve Reconstruction With Use Of Pericardial Leaflets In Adults With Bicuspid Aortic Valve Disease: Early And Midterm Outcomes, Meong Gun Song, Hyun Suk Yang, Jong Bum Choi, Je Kyoun Shin, Hyun Keun Chee, Jun Seok Kim
The Texas Heart Institute Journal
In this study, we retrospectively analyzed the outcomes of adults with bicuspid aortic valve (BAV) disease who underwent aortic valve reconstructive surgery (AVRS), consisting of replacement of the diseased BAV with 2 or 3 pericardial leaflets plus fixation of the sinotubular junction for accurate and constant leaflet coaptation. From December 2007 through April 2013, 135 consecutive patients (mean age, 49.2 ± 13.1 yr; 73.3% men) with symptomatic BAV disease underwent AVRS. Raphe was observed in 84 patients (62.2%), and the remaining 51 patients had pure BAV without raphe. A total of 122 patients (90.4%) underwent 3-leaflet reconstruction, and 13 (9.6%) …

Percutaneous Repair Of Post-Myocardial Infarction Ventricular Septal Defect: Current Approaches And Future Perspectives, Maria D Baldasare, Mark Polyakov, Glenn W Laub, Joseph T Costic, Daniel J Mccormick, Sheldon Goldberg
The Texas Heart Institute Journal
Post-myocardial infarction ventricular septal defect is a devastating complication of ST-elevation myocardial infarction. Although surgical intervention is considered the gold standard for treatment, it carries high morbidity and mortality rates. We present 2 cases that illustrate the application of percutaneous closure of a post-myocardial infarction ventricular septal defect: the first in a patient who had undergone prior surgical closure and then developed a new shunt, and the second as a bridge to definitive surgery in a critically ill patient.

Mastl Kinase, A Promising Therapeutic Target, Promotes Cancer Recurrence., Ling Wang, Vivian Q. Luong, Peter J. Giannini, Aimin Peng
Journal Articles: College of Dentistry
Mastl kinase promotes mitotic progression and cell cycle reentry after DNA damage. We report here that Mastl is frequently upregulated in various types of cancer. This upregulation was correlated with cancer progression in breast and oral cancer, poor patient survival in breast cancer, and tumor recurrence in head and neck squamous cell carcinoma. We further investigated the role of Mastl in tumor resistance using cell lines derived from the initial and recurrent tumors of the same head and neck squamous cell carcinoma patients. Ectopic expression of Mastl in the initial tumor cells strongly promoted cell proliferation in the presence of …

Rothman Institute Faculty Papers
BACKGROUND: The presence of leukocyte esterase in the synovial fluid has recently been proposed as a marker for periprosthetic joint infection. However, the sensitivity and specificity of leukocyte esterase has not been determined when matched for the current, most inclusive Musculoskeletal Infection Society (MSIS) criteria for periprosthetic joint infection.
METHODS: The presence of leukocyte esterase was prospectively evaluated in synovial joint aspirates from hips and knees from May 2009 to May 2013. The cohort consisted of 189 hip and knee aspirations (fifty-two positive and 137 negative for infection). If the aspirate was bloody, a centrifuge was used to precipitate red …

Department of Urology Faculty Papers
BACKGROUND AND PURPOSE: Assessing the severity of upper tract urothelial carcinoma (UTUC) has been difficult because of inadequate biopsy specimens. Additional predictive parameters of disease stage would be useful when deciding a treatment plan; it has been suggested that preoperative hydronephrosis can be a surrogate. We examined the relationship between preoperative ipsilateral renal obstruction identified by imaging with final pathologic stage after nephroureterectomy (NU) for UTUC. We then analyzed those patients with ipsilateral renal obstruction and examined if tumor location is associated with an advanced pathologic stage.
METHODS: Patients who underwent NU for UTUC between the years 2001 to 2013 …

Local Population Characteristics And Hemoglobin A1c Testing Rates Among Diabetic Medicare Beneficiaries, Laura C. Yasaitis, Thomas Bubolz, Jonathan S. Skinner, Amitabh Chandra
Dartmouth Scholarship
Background: Proposed payment reforms in the US healthcare system would hold providers accountable for the care delivered to an assigned patient population. Annual hemoglobin A1c (HbA1c) tests are recommended for all diabetics, but some patient populations may face barriers to high quality healthcare that are beyond providers' control. The magnitude of fine-grained variations in care for diabetic Medicare beneficiaries, and their associations with local population characteristics, are unknown.
Methods: HbA1c tests were recorded for 480,745 diabetic Medicare beneficiaries. Spatial analysis was used to create ZIP code-level estimated testing rates. Associations of testing rates with local population characteristics that are outside …

OBJECTIVE: We assessed salience of subjective memory complaints (SMCs) by older individuals as a predictor of subsequent cognitive impairment while accounting for risk factors and eventual neuropathologies.
METHODS: Subjects (n = 531) enrolled while cognitively intact at the University of Kentucky were asked annually if they perceived changes in memory since their last visit. A multistate model estimated when transition to impairment occurred while adjusting for intervening death. Risk factors affecting the timing and probability of an impairment were identified. The association between SMCs and Alzheimer-type neuropathology was assessed from autopsies (n = 243).
RESULTS: SMCs were …

Off-Pump Myocardial Revascularization In A High-Risk Patient With Essential Thrombocythemia, Ahmad K Darwazah, Hamad Madi, Rami Zagha, Yahia Hawash
The Texas Heart Institute Journal
Essential thrombocythemia is a rare type of myeloproliferative disorder. Cerebral, myocardial, and peripheral thrombosis are all frequent complications of the disease.
A 71-year-old man presented with severe coronary artery disease, associated with cerebral vascular ischemic changes and erythromelalgia. His platelet count was 1,486 ×103/μL. The patient underwent successful myocardial revascularization by means of an off-pump technique after his platelet count had been reduced by hydroxycarbamide administration.
We conclude that the use of off-pump cardiopulmonary bypass in high-risk patients with essential thrombocythemia is safe. Reducing platelet count via the administration of hydroxycarbamide and the careful balancing of antiplatelets and anticoagulants is …

The Texas Heart Institute Journal
The internal thoracic artery (ITA) is typically harvested from the chest wall by means of conventional electrocautery. We investigated the effects of electrocautery on endothelial-cell and vessel-wall morphology at the ultrastructural level during ITA harvesting. Internal thoracic artery specimens from 20 patients who underwent elective coronary artery bypass grafting were investigated in 2 groups. The ITA grafts were sharply dissected with use of a scalpel and clips in the control group (n=10) and were harvested by means of electrocautery in the study group (n=10). Each sample was evaluated for intimal, elastic-tissue, muscular-layer, and adventitial changes. Free flow was measured intraoperatively. …

Chronic obstructive pulmonary disease (COPD), one of the most common chronic diseases and a leading cause of death, has historically been considered a disease of men. However, there has been a rapid increase in the prevalence, morbidity, and mortality of COPD in women over the last two decades. This has largely been attributed to historical increases in tobacco consumption among women. But the influence of sex on COPD is complex and involves several other factors, including differential susceptibility to the effects of tobacco, anatomic, hormonal, and behavioral differences, and differential response to therapy. Interestingly, nonsmokers with COPD are more likely …

Musculoskeletal Safety Outcomes Of Patients Receiving Daptomycin With Hmg-Coa Reductase Inhibitors, Christopher M. Bland, P Brandon Bookstaver, Z Kevin Lu, Brianne L. Dunn, Kathey Fulton Rumley
Faculty Publications
Daptomycin, a cyclic lipopeptide antibiotic, and 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors (statins) are commonly administered in the inpatient setting and are associated with creatine phosphokinase (CPK) elevations, myalgias, and muscle weakness. Safety data for coadministration of daptomycin with statins are limited. To determine the safety of coadministration of daptomycin with statin therapy, a multicenter, retrospective, observational study was performed at 13 institutions in the Southeastern United States. Forty-nine adult patients receiving statins concurrently with daptomycin were compared with 171 patients receiving daptomycin without statin therapy. Detailed information, including treatment indication and duration, infecting pathogen, baseline and subsequent CPK levels, and …

While discussions on ageing previously centred on dependency ratios and healthcare infrastructure, there has been a growing attention to the other aspects of growing old, such as its social and emotional dimensions. There has also been a move in recent years to rethink the construct of ageing an frame it in a more positive way.In this paper we document some of the results derived from the Perception and Attitudes towards Ageing and Seniors (PATAS) survey completed in early 2014. These results delve into respondents’ beliefs about achieving successful ageing — what it constitutes how it can be achieved and respondents’ …

We test the hypothesis that climate and environmental conditions are becoming favorable for dengue transmission in San Juan, Puerto Rico. Sea Level Pressure (SLP), Mean Sea Level (MSL), Wind, Sea Surface Temperature (SST), Air Surface Temperature (AST), Rainfall, and confirmed dengue cases were analyzed. We evaluated the dengue incidence and environmental data with Principal Component Analysis, Pearson correlation coefficient, Mann-Kendall trend test and logistic regressions. Results indicated that dry days are increasing and wet days are decreasing. MSL is increasing, posing higher risk of dengue as the perimeter of the San Juan Bay estuary expands and shorelines move inland. Warming …

Return To Work After Stroke: A Nursing State Of The Science., Catherine Harris, Phd, Mba, Crnp
College of Nursing Faculty Papers & Presentations
There is a lack of research related to return to work (RTW) after acute ischemic stroke. Historically considered a disease of the elderly, acute ischemic stroke studies have not routinely used return to work as an outcome. Major stroke trials have not routinely collected this data as an endpoint. However, the mean age for acute ischemic stroke (AIS) has declined to 69 years of age, while the incidence in patients under the age of 55 has increased to 19%1-3. Changes in retirement age have also affected RTW as a consideration in stroke patients. Failure to RTW after recovery …

Division of Gastroenterology and Hepatology Faculty Papers
BACKGROUND: Polyethylene glycol 3350 plus sports drink (PEG-SD) is a hypo-osmotic purgative commonly used for colonoscopy, though little safety data are available.
AIM: To evaluate the effect of PEG-SD on serum sodium (Na) and other electrolytes compared with PEG-electrolyte solution (PEG-ELS).
METHODS: We performed a single center, prospective, randomised, investigator-blind comparison of PEG-ELS to PEG-SD in out-patients undergoing colonoscopy. Laboratories were obtained at baseline and immediately before and after colonoscopy. The primary endpoint was development of hyponatraemia (Na/L) the day of colonoscopy. Changes in electrolyte levels were computed as the difference between the lowest value on the day of colonoscopy …

A Qualitative Study Of The Impact Of Severe Asthma And Its Treatment Showing That Treatment Burden Is Neglected In Existing Asthma Assessment Scales., Michael E. Hyland, Ben Whalley, Rupert C. Jones, Matthew Masoli
School of Psychology
BACKGROUND: People with severe asthma experience significant respiratory symptoms and suffer adverse effects of oral corticosteroids (OCS), including disturbed mood and physical symptoms. OCS impacts on health-related quality of life (HRQoL) have not been quantified. Asthma HRQoL scales are valid as outcome measures for patients requiring OCS only if they assess the deficits imposed by OCS. AIMS: The aim of this study was to compare the burden of disease and treatment in patients with severe asthma with items in eight asthma-specific HRQoL scales. METHODS: Twenty-three patients with severe asthma recruited from a severe asthma clinic were interviewed about the impact …

BACKGROUND: Although genome wide studies have associated single nucleotide polymorphisms (SNP)s near PICALM with Alzheimer's disease (AD), the mechanism underlying this association is unclear. PICALM is involved in clathrin-mediated endocytosis and modulates Aß clearance in vitro. Comparing allelic expression provides the means to detect cis-acting regulatory polymorphisms. Thus, we evaluated whether PICALM showed allele expression imbalance (AEI) and whether this imbalance was associated with the AD-associated polymorphism, rs3851179.
RESULTS: We measured PICALM allelic expression in 42 human brain samples by using next-generation sequencing. Overall, PICALM demonstrated equal allelic expression with no detectable influence by rs3851179. A single sample demonstrated …

OBJECTIVES: Our objective is to report prevalence of motoric cognitive risk syndrome (MCR), a newly described predementia syndrome characterized by slow gait and cognitive complaints, in multiple countries, and its association with dementia risk.
METHODS: Pooled MCR prevalence analysis of individual data from 26,802 adults without dementia and disability aged 60 years and older from 22 cohorts from 17 countries. We also examined risk of incident cognitive impairment (Mini-Mental State Examination decline ≥4 points) and dementia associated with MCR in 4,812 individuals without dementia with baseline Mini-Mental State Examination scores ≥25 from 4 prospective cohort studies using Cox models adjusted …
