Role Of A Plausible Nuisance Contributor In The Declining Obesity-Mortality Risks Over Time., Tapan Mehta, Nicholas M. Pajewski, Scott W. Keith, Kevin Fontaine, David B. Allison

Department of Pharmacology and Experimental Therapeutics Faculty Papers

CONTEXT: Recent analyses of epidemiological data including the National Health and Nutrition Examination Survey (NHANES) have suggested that the harmful effects of obesity may have decreased over calendar time. The shifting BMI distribution over time coupled with the application of fixed broad BMI categories in these analyses could be a plausible "nuisance contributor" to this observed change in the obesity-associated mortality over calendar time.

OBJECTIVE: To evaluate the extent to which observed temporal changes in the obesity-mortality association may be due to a shifting population distribution for body mass index (BMI), coupled with analyses based on static, broad BMI categories. …

Manuscripts, Articles, Book Chapters and Other Papers

Several medical professional organizations, including the American Academy of Pediatrics, recommend that parents avoid hitting children for disciplinary purposes (e.g., spanking) and that medical professionals advise parents to use alternative methods. The extent to which medical professionals continue to endorse spanking is unknown. This study is the first to examine attitudes about spanking among staff throughout medical settings, including non-direct care staff. A total of 2580 staff at a large general medical center and 733 staff at a children's hospital completed an online survey; respondents were roughly divided between staff who provide direct care to patients (e.g., physicians, nurses) and …

Performance Of A1c Versus Ogtt For The Diagnosis Of Prediabetes In A Community-Based Screening, Jenny E. Camacho, Vallabh O. Shah, Ronald Schrader, Craig S. Wong, Mark R. Burge

Pediatrics Research and Scholarship

OBJECTIVE: Reliable identification of individuals at risk for developing diabetes is critical to instituting preventative strategies. Studies suggest that the accuracy of using hemoglobin A1c as a sole diagnostic criterion for diabetes may be variable across different ethnic groups. We postulate that there will be lack of concordance between A1c and the oral glucose tolerance test (OGTT) for diagnosing prediabetes across Hispanic and non-Hispanic white (NHW) populations.

METHODS: A total of 218 asymptomatic adults at risk for type 2 diabetes (T2D) were assessed with A1c and OGTT for the diagnosis of prediabetes. Glucose homeostasis status was assigned as no diabetes …

Conventional cytogenetics and interphase fluorescence in situ hybridization (FISH) identify high-risk multiple myeloma (HRM) populations characterized by poor outcomes. We analyzed these differences among HRM versus non-HRM populations after upfront autologous hematopoietic cell transplantation (autoHCT). Between 2008 and 2012, 715 patients with multiple myeloma identified by FISH and/or cytogenetic data with upfront autoHCT were identified in the Center for International Blood and Marrow Transplant Research database. HRM was defined as del17p, t(4;14), t(14;16), hypodiploidy (-Y) or chromosome 1 p and 1q abnormalities; all others were non-HRM. Among 125 HRM patients (17.5%), induction with bortezomib and immunomodulatory agents (imids) was higher …

PURPOSE: Huntington disease (HD) is an incurable terminal disease. Thus, end of life (EOL) concerns are common in these individuals. A quantitative measure of EOL concerns in HD would enable a better understanding of how these concerns impact health-related quality of life. Therefore, we developed new measures of EOL for use in HD.

METHODS: An EOL item pool of 45 items was field tested in 507 individuals with prodromal or manifest HD. Exploratory and confirmatory factor analyses (EFA and CFA, respectively) were conducted to establish unidimensional item pools. Item response theory (IRT) and differential item functioning analyses were applied to …

PURPOSE: Huntington disease (HD) is a chronic, debilitating genetic disease that affects physical, emotional, cognitive, and social health. Existing patient-reported outcomes (PROs) of health-related quality of life (HRQOL) used in HD are neither comprehensive, nor do they adequately account for clinically meaningful changes in function. While new PROs examining HRQOL (i.e., Neuro-QoL-Quality of Life in Neurological Disorders and PROMIS-Patient-Reported Outcomes Measurement Information System) offer solutions to many of these shortcomings, they do not include HD-specific content, nor have they been validated in HD. HDQLIFE addresses this by validating 12 PROMIS/Neuro-QoL domains in individuals with HD and by using established PROMIS …

Recurrent Violent Injury: Magnitude, Risk Factors, And Opportunities For Intervention From A Statewide Analysis., Elinore Kaufman, Kristin L. Rising, Md, Ms, Douglas J. Wiebe, David J. Ebler, Marie L. Crandall, M. Kit Delgado

Department of Emergency Medicine Faculty Papers

INTRODUCTION: Although preventing recurrent violent injury is an important component of a public health approach to interpersonal violence and a common focus of violence intervention programs, the true incidence of recurrent violent injury is unknown. Prior studies have reported recurrence rates from 0.8% to 44%, and risk factors for recurrence are not well established.

METHODS: We used a statewide, all-payer database to perform a retrospective cohort study of emergency department visits for injury due to interpersonal violence in Florida, following up patients injured in 2010 for recurrence through 2012. We assessed risk factors for recurrence with multivariable logistic regression and …

Elevated Integrin Α6Β4 Expression Is Associated With Venous Invasion And Decreased Overall Survival In Non-Small Cell Lung Cancer, Rachel L. Stewart, Dava West, Chi Wang, Heidi L. Weiss, Tamas S. Gal, Eric B. Durbin, William O'Connor, Min Chen, Kathleen L. O'Connor

Pathology and Laboratory Medicine Faculty Publications

Lung cancer carries a poor prognosis and is the most common cause of cancer-related death worldwide. The integrin α6β4, a laminin receptor, promotes carcinoma progression in part by cooperating with various growth factor receptors to facilitate invasion and metastasis. In carcinoma cells with mutant TP53, the integrin α6β4 promotes cell survival. TP53 mutations and integrin α6β4 overexpression co-occur in many aggressive malignancies. Because of the high frequency of TP53 mutations in lung squamous cell carcinoma (SCC), we sought to investigate the association of integrin β4 expression with clinicopathologic features and survival in non–small cell lung cancer (NSCLC). We constructed …

Preventive Medicine and Environmental Health Faculty Publications

Background: The morning tends to be the most difficult time of day for many patients with chronic obstructive pulmonary disease (COPD) when symptoms can limit one’s ability to perform even simple activities. Morning symptoms have been linked to higher levels of work absenteeism, thereby increasing the already substantial economic burden associated with COPD. A validated patient-reported outcome (PRO) instrument designed to capture morning symptoms will allow for a more comprehensive approach to the evaluation of treatment benefit in COPD clinical trials.

Methods: A qualitative interview study was conducted among a sample of symptomatic adults with COPD. Concept elicitation interviews ( …

Department of Anesthesiology Faculty Papers

High-dose opioid administration is associated with significant adverse events. Evidence suggests that low-dose ketamine infusions improve perioperative analgesia over conventional opioid management, but usage is highly variable. Ketamine's adverse drug effects (ADEs) are well known, but their prevalence during low-dose infusions in a clinical setting and how often they lead to infusion discontinuation are unknown. The purposes of this study were 3-fold: (1) to identify patient factors associated with initiation of ketamine infusions during spine surgery, (2) to identify specific spine procedures in which ketamine has been used most frequently, and (3) to identify ADEs associated with postoperative ketamine infusions …

The microbiome impacts human health and disease. Until recently, human breast tissue and milk were presumed to be sterile. Here, we investigated the presence of microbes in the nipple aspirate fluid (NAF) and their potential association with breast cancer. We compared the NAF microbiome between women with a history of breast cancer (BC) and healthy control women (HC) using 16S rRNA gene amplicon sequencing. The NAF microbiome from BC and HC showed significant differences in community composition. Two Operational Taxonomic Units (OTUs) showed differences in relative abundances between NAF collected from BC and HC. In NAF collected from BC, there …

Michael D Pasquale MD, FACS, FCCM

BACKGROUND: Recent reports showed lack of effectiveness of pulmonary artery catheterization in critically ill medical patients and relatively late-stage surgical patients with organ failure. Since invasive monitoring requires critical care environments, the early hemodynamic patterns may have been missed. Ideally, early noninvasive hemodynamic monitoring systems, if reliable, could be used as the "front end" of invasive monitoring to supply more complete descriptions of circulatory pathophysiology.

OBJECTIVES: To evaluate the accuracy and reliability of noninvasive hemodynamic monitoring consisting of a new bioimpedance method for estimating cardiac output combined with arterial BP, pulse oximetry, and transcutaneous PO2 and PCO2; we compared this …

OBJECTIVES: Determine the effect of early (days 3-5) or late (days 10-14) tracheostomy on intensive care unit length of stay (ICU LOS), frequency of pneumonia, and mortality, and evidence of short-term or long-term pharyngeal, laryngeal, or tracheal injury in head trauma, non-head trauma, and critically ill nontrauma patients.

STUDY DESIGN: Randomized, prospective.

SETTING: Five Level I trauma centers.

METHODS: Data were obtained prospectively and included Acute Physiology and Chronic Health Evaluation III score (AIII), Glasgow Coma Scale score, Emergency Room Trauma Score, Injury Severity Score, Acute Injury Score, type of endotracheal tube or tracheostomy, level of positive end-expiratory pressure, and …

BACKGROUND: Cirrhosis as an independent predictor of poor outcomes in trauma patients was identified in 1990. We hypothesized that the degree of preinjury hepatic dysfunction is, by itself, an independent predictor of mortality.

STUDY DESIGN: The trauma registry at our Level I trauma center was queried for all ICD-9 codes for liver disease from 1999 to 2003, and patients were categorized as having Child-Turcotte-Pugh (CTP) class A, B, or C cirrhosis. Data analyzed included age, mechanism of injury, Abbreviated Injury Score (AIS), Injury Severity Score (ISS), Glasgow Coma Score (GCS), hospital length of stay, ventilator days, procedures performed, transfusion of …

OBJECTIVE: To determine the potential impact of defining criteria for "dead on arrival" (DOA) on a Level I trauma center.

METHODS: From 1990 to 1994, trauma patients having cardiopulmonary resuscitation (CPR) performed by certified prehospital personnel were reviewed for time of CPR, outcome, and costs to determine whether any benefit would have been realized had DOA criteria been followed.

RESULTS: A total of 106 patients had prehospital CPR; 20 did not meet DOA criteria and underwent resuscitation, three survived (15%). Eighty-six patients met DOA criteria; 16 were pronounced dead without further resuscitative efforts (in-hospital costs of $200/patient), while 70 (81%) …

BACKGROUND: The purpose of this study was to evaluate our experience with blunt thoracic aortic injury and identify factors predictive of outcome.

METHODS: Hospital charts, trauma registry data, and autopsies of 64 patients with blunt thoracic aortic injury from 1988 to 1995 were reviewed.

RESULTS: Patients were identified and segregated based on admission physiology. Group 1 patients (n = 19) arrived in arrest. Group 2 patients (n = 10) arrived in shock with systolic BP 90. Group 3 patients (n = 35) arrived with systolic BP>90. All patients in groups 1 and 2 expired. Injury Severity Scores for nonsurvivors …
