Hips Can Lie: Impact Of Excluding Isolated Hip Fractures On External Benchmarking Of Trauma Center Performance, David Gomez, Barbara Haas, Mark Hemmila, Michael Pasquale, Sandra Goble, Melanie Neal, N Mann, Wayne Meredith, Henry Cryer, Shahid Shafi, Avery Nathens

Michael D Pasquale MD, FACS, FCCM

BACKGROUND: Trauma centers (TCs) vary in the inclusion of patients with isolated hip fractures (IHFs) in their registries. This inconsistent case ascertainment may have significant implications on the assessment of TC performance and external benchmarking efforts. METHODS: Data were derived from the National Trauma Data Bank (2007-8.1). We included patients (aged 16 years or older) with Injury Severity Score value ≥ 9 who were admitted to Level I and II TCs. To ensure data quality, we limited the study to TC that routinely reported comorbidities and Abbreviated Injury Scale codes. IHF were defined as patients, aged 65 years or older, …

The Acute Effects Of Moderately Loaded Concentric-Only Quarter Squats On Vertical Jump Performance, Aaron Crum, Naoki Kawamori, Michael Stone, Guy Haff

Greg Haff

2012-Limited research exists examining the effect of moderately loaded conditioning activities that are employed as part of a strength-power potentiating complex (SPPC). Additionally, no studies to date have explored the effects of using a concentric-only quarter back squat protocol as part of an SPPC. Therefore, the purpose of this study was to examine the effects of a moderately loaded (50-65% of 1RM) concentric-only quarter back squat protocol on the occurrence of potentiation effects at various time points. Twenty men who could quarter back squat a minimum of 2.4 times their body mass (3.7 ±: 0.7 kg-per body mass) participated in …

Trust And Satisfaction With Physicians, Insurers, And The Medical Profession, Rajesh Balkrishnan, Elizabeth Dugan, Fabian Camacho, Mark Hall

Elizabeth Dugan

BACKGROUND: Conceptual or theoretical analysts of trust in medical settings distinguish among markedly different objects or types of trust. However, little is known about how similar or different these types of trust are in reality and the relationship of trust with satisfaction. OBJECTIVES: This exploratory study conducted a comparison among trust in one's personal physician, health insurer, and in the medical profession, and examined whether the relationship between trust and satisfaction differs according to the type of trust in question. RESEARCH DESIGN: Random national telephone survey using validated multi-item measures of trust and satisfaction. SUBJECTS: A total of 1117 individuals …

Why African-American Women Are At Greater Risk For Pregnancy-Related Death, Margaret Harper, Elizabeth Dugan, Mark Espeland, Anibal Martinez-Borges, Cynthia Mcquellon

Elizabeth Dugan

PURPOSE: Our study aim was to identify factors that may contribute to the racial disparity in pregnancy-related mortality.

METHODS: We examined differences in severity of disease, comorbidities, and receipt of care among 608 (304 African-American and 304 white) consecutive patients of non-Hispanic ethnicity with one of three pregnancy-related morbidities (pregnancy-related hypertension, puerperal infection, and hemorrhage) from hospitals selected at random from a statewide region.

RESULTS: African-American women had more severe hypertension, lower hemoglobin concentrations preceding hemorrhage, more antepartum hospital admissions, and a higher rate of obesity. The rate of surgical intervention for hemorrhage was lower among African-Americans, although the severity …

An Exploration Of Patients' Trust In Physicians In Training, Denise Bonds, Kristie Foley, Elizabeth Dugan, Mark Hall, Pam Extrom

Elizabeth Dugan

Several characteristics associated with patient trust are identified. To determine the level of trust patients from disadvantaged circumstances have in their primary care resident physician, and to determine patient and physician characteristics that predict trust, we administered a survey to randomly selected primary care patients of an academic medical center staffed by internal medicine residents after a visit to their primary care provider. Participants were adults. The group was racially diverse (50% non-white), English-speaking, and from lower socioeconomic groups. The 10-page survey consisted of 7 sections (Physician Trust Scale, Patient Demographics, Patient Health and Well-Being, Patient-Physician Relationship Characteristics, Global Doctor …

The Impact On Patient Trust Of Legalising Physician Aid In Dying, Mark Hall, Felicia Trachtenberg, Elizabeth Dugan

Elizabeth Dugan

OBJECTIVE: Little empirical evidence exists to support either side of the ongoing debate over whether legalising physician aid in dying would undermine patient trust. DESIGN: A random national sample of 1117 US adults were asked about their level of agreement with a statement that they would trust their doctor less if "euthanasia were legal [and] doctors were allowed to help patients die". RESULTS: There was disagreement by 58% of the participants, and agreement by only 20% that legalising euthanasia would cause them to trust their personal physician less. The remainder were neutral. These attitudes were the same in men and …

The Impact Of A Video Intervention On The Use Of Low Vision Assistive Devices, Robert Goldstein, Elizabeth Dugan, Felicia Trachtenberg, Eli Peli

Elizabeth Dugan

PURPOSE: An image-enhanced educational and motivational video was developed for patients with low vision and their caretakers. Impact on knowledge, self-efficacy, and attitudes was assessed. METHODS: The video incorporated cognitive restructuring to change emotional response; a "virtual home"; a veridical simulation of vision with age-related macular degeneration and contrast enhancement of the video. Subjects (median age 77.5) were randomized into control (n=79) and intervention (n=75) groups. Telephone interviews were at baseline, 2 weeks and 3 months. Main outcome measures were: knowledge (eight questions), self-efficacy score (seven questions), adaptive behaviors (10 questions), willingness to use devices, and emotional response (4-point scales). …

Prevalence Of Sexual Abuse Among Women Seeking Gynecologic Care In Germany, Ursula Peschers, Janice Du Mont, Katharina Jundt, Mona Pfurtner, Elizabeth Dugan, Gunther Kindermann

Elizabeth Dugan

OBJECTIVE: To estimate the prevalence of sexual abuse among patients seen for gynecologic care in Germany. METHODS: A short anonymous questionnaire was distributed to 1157 women attending a gynecologic outpatient clinic at a large urban teaching hospital. Data collected using the questionnaire included patient characteristics, sexual abuse history, and screening practices. Women who reported that they had been abused were asked if they had ever discussed the issue with their gynecologist. RESULTS: A total of 1075 questionnaires were returned, for a response rate of 92.9%. Almost half (n = 479 [44.6%]) of the women surveyed reported that they had been …

Racial Disparity In Pregnancy-Related Mortality Following A Live Birth Outcome, Margaret Harper, Mark Espeland, Elizabeth Dugan, Robert Meyer, Kathy Lane, Sharon Williams

Elizabeth Dugan

PURPOSE: African-American women have a 2- to 4-fold increased risk of pregnancy-related death compared with Caucasian women. We conducted this study to determine if differences in a combination of socioeconomic and medical risk factors may explain this racial disparity in pregnancy-related death. METHODS: Pregnancy-related deaths of African-American (N=60) and Caucasian (N=47) women were identified from review of pregnancy-associated deaths (N=400) ascertained through cause of death on death certificates, electronic linkage of birth and death files, and review of the hospital discharge database for the State of North Carolina, during the period between 1992 and 1998. Controls (N=3404) were randomly selected …

How Patients' Trust Relates To Their Involvement In Medical Care, Felicia Trachtenberg, Elizabeth Dugan, Mark Hall

Elizabeth Dugan

OBJECTIVES: To examine the connection between patients' trust and their attitudes toward seeking care, participating in medical decision making, and adhering to treatment recommendations. METHODS: Data were collected from a national telephone survey of English-speaking adults (N=553) in 1999. Eligibility requirements were some type of public or private health care coverage and having seen a physician or other health professional at least twice in the past 2 years. Five questions on preferred role in medical care were asked. Trust in physicians and satisfaction with care were separately measured using validated scales. RESULTS: The most significant predictor of patients' preferred role …

Addressing The Controversy Of Rate-Versus-Rhythm Control In Atrial Fibrillation, Tahmeed Contractor, Vadim Levin, Ravi Desai, Francis E Marchlinski

Vadim A Levin MD

Atrial fibrillation is the most common sustained cardiac arrhythmia and significantly increases patient risk of stroke, cardiomyopathy, and mortality. Rate versus rhythm control as the "best" treatment strategy remains an issue of considerable, ongoing debate. A multitude of clinical trials have compared the 2 strategies and have not shown any benefit of one approach over the other. However, the trials were conducted in specific subgroups of patients and demonstrated low success rates with antiarrhythmic drug (AAD) therapy and a high incidence of adverse AAD effects. Sub-analyses of the trials have confirmed that successful rhythm control with sinus rhythm restoration is …

Dengue Virus-Specific Human Cd4+ T-Lymphocyte Responses In A Recipient Of An Experimental Live-Attenuated Dengue Virus Type 1 Vaccine: Bulk Culture Proliferation, Clonal Analysis, And Precursor Frequency Determination, Sharone Green, Ichiro Kurane, Robert Edelman, Carol 0. Tacket, Kenneth H. Eckels, David W. Vaughn, Charles H. Hoke, Francis A. Ennis

Sharone Green

We analyzed the CD4+ T-lymphocyte responses to dengue, West Nile, and yellow fever viruses 4 months after immunization of a volunteer with an experimental live-attenuated dengue virus type 1 vaccine (DEN-1 45AZ5). We examined bulk culture proliferation to noninfectious antigens, determined the precursor frequency of specific CD4+ T cells by limiting dilution, and established and analyzed CD4+ T-cell clones. Bulk culture proliferation was predominantly dengue virus type 1 specific with a lesser degree of cross-reactive responses to other dengue virus serotypes, West Nile virus, and yellow fever virus. Precursor frequency determination by limiting dilution in the presence of noninfectious dengue …

The Safety And Tolerability Of An Hiv-1 Dna Prime-Protein Boost Vaccine (Dp6-001) In Healthy Adult Volunteers, Jeffrey Kennedy, Mary Co, Sharone Green, Karen Longtine, Jaclyn Longtine, Melissa O'Neill, Janice Adams, Alan Rothman, Qiao Yu, Renita Johnson-Leva, Ranajit Pal, Shixia Wang, Shan Lu, Phillip Markham

This report describes the safety observations following administration of a polyvalent DNA prime-protein boost HIV-1 vaccine formulated with adjuvant QS21. Local injection site reactions were the most common (65% of subjects), and included type IV delayed-type hypersensitivity (DTH) reactions at prior DNA inoculation sites in 12 of 28 (43%) subjects following protein vaccination. Systemic reactions revealed two cases of vasculitis temporally related to inoculation with recombinant Env protein+QS21 adjuvant. Questions remain regarding the cause of the vasculitis, but the unique DTH observation may have contributed to the high level of immune responses previously reported for this vaccine.

Cross-Subtype Antibody And Cellular Immune Responses Induced By A Polyvalent Dna Prime-Protein Boost Hiv-1 Vaccine In Healthy Human Volunteers, Shixia Wang, Jeffrey Kennedy, Kim West, David Montefiori, Scott Coley, John Lawrence, Siyuan Shen, Sharone Green, Alan Rothman, Francis Ennis, James Arthos, Ranajit Pal, Phillip Markham, Shan Lu

An optimally effective AIDS vaccine would likely require the induction of both neutralizing antibody and cell-mediated immune responses, which has proven difficult to obtain in previous clinical trials. Here we report on the induction of Human Immunodeficiency Virus Type-1 (HIV-1)-specific immune responses in healthy adult volunteers that received the multi-gene, polyvalent, DNA prime-protein boost HIV-1 vaccine formulation, DP6-001, in a Phase I clinical trial conducted in healthy adult volunteers of both genders. Robust cross-subtype HIV-1-specific T cell responses were detected in IFNgamma ELISPOT assays. Furthermore, we detected high titer serum antibody responses that recognized a wide range of primary HIV-1 …
