Risk Factors For Wound Complications After Ankle Fracture Surgery., Adam G Miller, Andrew Margules, Steven M Raikin
Department of Orthopaedic Surgery Faculty Papers
BACKGROUND: The overall rate of complications after ankle fracture fixation varies between 5% and 40% depending on the population investigated, and wound complications have been reported to occur in 1.4% to 18.8% of patients. Large studies have focused on complications in terms of readmission, but few studies have examined risk factors for wound-related issues in the outpatient setting in a large number of patients. A review was performed to identify risk factors for wound complications tracked in the hospital and outpatient setting.
METHODS: Four hundred and seventy-eight patients underwent open reduction and internal fixation of an ankle fracture between 2003 …

BACKGROUND: Limited evidence suggests that intimate partner violence (IPV) may be associated with poorer cancer outcomes. We hypothesized that timing and type of IPV as well as childhood sexual abuse (CSA) may negatively affect depression, perceived stress, and cancer-related well-being.
METHODS: This was a cross-sectional study of women diagnosed with either breast, cervical, or colorectal cancer in the prior 12 months included in the Kentucky Cancer Registry. Consenting women were interviewed by phone (n=553). Multivariate analysis of covariance (MANCOVA) was used to determine the association between IPV (37% lifetime prevalence) and type, timing, and the range of correlated cancer-related well-being …

The Differential Effects Of Maternal Age, Race/Ethnicity And Insurance On Neonatal Intensive Care Unit Admission Rates., Beatriz E De Jongh, Robert Locke, David A Paul, Matthew Hoffman
Department of Pediatrics Faculty Papers
BACKGROUND: Maternal race/ethnicity, age, and socioeconomic status (SES) are important factors determining birth outcome. Previous studies have demonstrated that, teenagers, and mothers with advanced maternal age (AMA), and Black/Non-Hispanic race/ethnicity can independently increase the risk for a poor pregnancy outcome. Similarly, public insurance has been associated with suboptimal health outcomes. The interaction and impact on the risk of a pregnancy resulting in a NICU admission has not been studied. Our aim was, to analyze the simultaneous interactions of teen/advanced maternal age (AMA), race/ethnicity and socioeconomic status on the odds of NICU admission.
METHODS: The Consortium of Safe Labor Database (subset …

OBJECTIVE: To determine if interindividual differences in plasma concentrations of 25-hydroxyvitamin D(3) (25(OH)D(3)) have pathophysiologic significance, we evaluated a cohort of female monkeys, seeking to identify associations with clinically relevant cardiovascular risk factors, including age, abdominal obesity (waist circumference), and high-density lipoprotein cholesterol (HDL-C).
METHODS: One hundred fifty-five female vervet monkeys (Chlorocebus aethiops sabaeus) aged 3-25 years consumed a typical western diet for 7-8 weeks that provided a woman's equivalent of approximately 1000 IU/day of vitamin D(3). Measurements of vitamin D(3) and HDL-C concentrations, as well as waist circumference, were obtained.
RESULTS: Among young monkeys (aged 3-5 years), compared to …

BACKGROUND: The purpose of this study was to assess postsurgical outcomes in active patients after primary repair of acute and chronic proximal hamstring tears.
HYPOTHESIS: Surgical treatment of both acute and chronic proximal hamstring avulsion injuries would result in improved patient outcomes using validated outcome scores and a hamstring-specific questionnaire, and operative repair of these injuries results in excellent outcomes with a high level of patient satisfaction, pain relief, and return to function.
STUDY DESIGN: Case series; Level of evidence, 4.
METHODS: Fifty-two patients who underwent proximal hamstring repair (26 male and 26 female; average age, 47.7 years) completed the …

BACKGROUND: Clinical trials often rely on echocardiographic measures of left ventricular size and function as surrogate end points. However, the quantitative impact of factors that affect the reproducibility of these measures is unknown. To address this issue, the National Heart, Lung, and Blood Institute-funded Pediatric Heart Network designed a longitudinal observational study of children with known or suspected dilated cardiomyopathy aged 0 to 22 years from eight pediatric clinical centers.
METHODS: Clinical data were collected together with 150 echocardiographic indices of left ventricular size and function. Separate observers performed duplicate echocardiographic imaging. Multiple observers performed measurements from three cardiac cycles …

Problem gambling is complex and often comorbid with other mental health problems. Unfortunately, gambling studies on comorbid psychiatric disorders among Chinese communities are extremely limited. The objectives of this study were to (a) determine the prevalence of comorbid psychiatric disorders among treatment-seeking pathological gamblers; (b) compare the demographic profiles and clinical features of pathological gamblers with and without comorbid psychiatric disorders; (c) explore the associations between pathological gambling and psychiatric disorders and their temporal relationship. Participants (N = 201) who sought gambling counseling were examined by making Axis-I diagnoses including mood disorders, schizophrenia spectrum disorders, substance use disorders, anxiety disorders, …
Personal Construction Of Cough Medicine Among Young Substance Abusers In Hong Kong, Daniel T. L. Shek
Personal Construction Of Cough Medicine Among Young Substance Abusers In Hong Kong, Daniel T. L. Shek
Pediatrics Faculty Publications
Although cough medicine abuse is a growing problem in many places, there is no study examining the views of young substance abusers toward cough medicine. The objective of this study was to examine personal constructions of cough medicine abusers via the repertory grid tests (N = 11). Several observations are highlighted from the study. First, personal constructions of cough medicine were mixed, including the benefits and harmful effects of its abuse. Second, although the informants perceived cough medicine to be addictive and harmful, they perceived cough medicine to be less addictive and less harmful than did heroin. Third, while the …
A Heuristic Solution Of The Identifiability Problem Of The Age-Period-Cohort Analysis Of Cancer Occurrence: Lung Cancer Example., Tengiz Mdzinarishvili, Simon Sherman
A Heuristic Solution Of The Identifiability Problem Of The Age-Period-Cohort Analysis Of Cancer Occurrence: Lung Cancer Example., Tengiz Mdzinarishvili, Simon Sherman
Journal Articles: Eppley Institute
BACKGROUND: The Age-Period-Cohort (APC) analysis is aimed at estimating the following effects on disease incidence: (i) the age of the subject at the time of disease diagnosis; (ii) the time period, when the disease occurred; and (iii) the date of birth of the subject. These effects can help in evaluating the biological events leading to the disease, in estimating the influence of distinct risk factors on disease occurrence, and in the development of new strategies for disease prevention and treatment.
METHODOLOGY/PRINCIPAL FINDINGS: We developed a novel approach for estimating the APC effects on disease incidence rates in the frame of …
Does International Normalized Ratio Level Predict Pulmonary Embolism?, Patricia Hansen, Benjamin Zmistowski, Camilo Restrepo, Javad Parvizi, Richard H Rothman
Does International Normalized Ratio Level Predict Pulmonary Embolism?, Patricia Hansen, Benjamin Zmistowski, Camilo Restrepo, Javad Parvizi, Richard H Rothman
Rothman Institute Faculty Papers
BACKGROUND: Preventing pulmonary embolism is a priority after major musculoskeletal surgery. The literature contains discrepant data regarding the influence of anticoagulation on the incidence of pulmonary embolism after joint arthroplasty. The American College of Chest Physicians guidelines recommend administration of oral anticoagulants (warfarin), aiming for an international normalized ratio (INR) level between 2 and 3. However, recent studies show aggressive anticoagulation (INR > 2) can lead to hematoma formation and increased risk of subsequent infection.
QUESTIONS/PURPOSES: We asked whether an INR greater than 2 protects against pulmonary embolism.
PATIENTS AND METHODS: We identified 9112 patients with 10,122 admissions for joint arthroplasty …

PURPOSE:
Fluorodeoxyglucose positron emission computed tomography (FDG-PET) hypometabolism is important for surgical planning in patients with temporal lobe epilepsy (TLE), but its significance remains unclear in patients who do not have evidence of mesial temporal sclerosis (MTS) on magnetic resonance imaging (MRI). We examined surgical outcomes in a group of PET-positive, MRI-negative patients and compared them with those of patients with MTS.
METHODS:
We queried the Thomas Jefferson University Surgical Epilepsy Database for patients who underwent anterior temporal lobectomy (ATL) from 1991 to 2009 and who had unilateral temporal PET hypometabolism without an epileptogenic lesion on MRI (PET+/MRI-). We compared …

OBJECTIVE: To determine whether there is an increased odds of mortality among trauma patients treated at hospitals with higher proportions of minority patients (ie, black and Hispanic patients combined).
DESIGN: Hospitals were categorized on the basis of the percentage of minority patients admitted with trauma. The adjusted odds of in-hospital mortality were compared between hospitals with less than 25% of patients who were minorities (the reference group) and hospitals with 25% to 50% of patients who were minorities and hospitals with more than 50% of patients who were minorities. Multivariate logistic regression (with generalized linear modeling and a cluster-correlated robust …
