Articles, Abstracts, and Reports

BACKGROUND: Hypothetically, delay between melanoma diagnosis and SLNB could affect outcomes, either adversely by allowing growth and dissemination of metastases, or beneficially by allowing development of an anti-melanoma immune response. Available data are conflicting about the effect of SLNB delay on patient survival. Our objective was to determine whether delay between initial diagnosis and SLNB affects outcomes in patients with cutaneous melanoma.

STUDY DESIGN: We performed query and analysis of a large prospectively maintained database of patients with primary cutaneous melanomas undergoing SLNB. An independent dataset from MSLT-1 (Multicenter Selective Lymphadenectomy Trial-1) was used for validation. Primary outcomes included disease-free …

Treatments For Opioid Use Disorder Among Pregnant And Reproductive-Aged Women., Dennis J. Hand, Vanessa L. Short, Diane J. Abatemarco

Department of Obstetrics and Gynecology Faculty Papers

The increased prevalence of opioid use disorder and access to medical insurance is subsequently increasing the likelihood that medical professionals will encounter individuals with opioid use disorder. Sharp increases in opioid use disorder among women mean that obstetricians, gynecologists, and other reproductive medicine providers may be especially likely to encounter such patients. Medical professionals' understanding of treatment for opioid use disorder and their roles in their patients' treatment may increase referrals to treatment, reduce stigma, and improve the quality of medical care. Treatment for opioid use disorder falls into four overlapping domains: medication management, medical care, behavioral/mental health care, and …

Echocardiographic Classification And Surgical Approaches To Double-Outlet Right Ventricle For Great Arteries Arising Almost Exclusively From The Right Ventricle, Kun-Jing Pang, Hong Meng, Sheng-Shou Hu, Hao Wang, David Hsi, Zhong-Dong Hua, Xiang-Bin Pan, Shou-Jun Li

The Texas Heart Institute Journal

Selecting an appropriate surgical approach for double-outlet right ventricle (DORV), a complex congenital cardiac malformation with many anatomic variations, is difficult. Therefore, we determined the feasibility of using an echocardiographic classification system, which describes the anatomic variations in more precise terms than the current system does, to determine whether it could help direct surgical plans. Our system includes 8 DORV subtypes, categorized according to 3 factors: the relative positions of the great arteries (normal or abnormal), the relationship between the great arteries and the ventricular septal defect (committed or noncommitted), and the presence or absence of right ventricular outflow tract …

Articles, Abstracts, and Reports

Emerging knowledge suggests that post-traumatic stress disorder (PTSD) pathophysiology is linked to the patients' epigenetic changes, but comprehensive studies examining genome-wide methylation have not been performed. In this study, we examined genome-wide DNA methylation in peripheral whole blood in combat veterans with and without PTSD to ascertain differentially methylated probes. Discovery was initially made in a training sample comprising 48 male Operation Enduring Freedom (OEF)/Operation Iraqi Freedom (OIF) veterans with PTSD and 51 age/ethnicity/gender-matched combat-exposed PTSD-negative controls. Agilent whole-genome array detected ~5600 differentially methylated CpG islands (CpGI) annotated to ~2800 differently methylated genes (DMGs). The majority (84.5%) of these CpGIs …

Normal Breast Tissue Dna Methylation Differences At Regulatory Elements Are Associated With The Cancer Risk Factor Age., Kevin C Johnson, E Andres Houseman, Jessica E King, Brock C Christensen

Faculty Research 2017

BACKGROUND: The underlying biological mechanisms through which epidemiologically defined breast cancer risk factors contribute to disease risk remain poorly understood. Identification of the molecular changes associated with cancer risk factors in normal tissues may aid in determining the earliest events of carcinogenesis and informing cancer prevention strategies.

METHODS: Here we investigated the impact cancer risk factors have on the normal breast epigenome by analyzing DNA methylation genome-wide (Infinium 450 K array) in cancer-free women from the Susan G. Komen Tissue Bank (n = 100). We tested the relation of established breast cancer risk factors, age, body mass index, parity, and …

Construction And Validation Of The Fatigue Impact And Severity Self-Assessment For Youth And Young Adults With Cerebral Palsy., Laura K Brunton, Doreen J Bartlett

Physical Therapy Publications

Purpose: The Fatigue Impact and Severity Self-Assessment (FISSA) was created to assess the impact, severity and self-management of fatigue for individuals with cerebral palsy (CP) aged 14-31.

Methods Used: Items were generated from a review of measures and interviews with individuals with CP. Focus groups with healthcare professionals were used for item reduction. A mailed survey was conducted (n=163/367) to assess the factor structure, known-groups validity and test-retest reliability.

Results Obtained: The final measure contained 31-items in two factors and discriminated between individuals expected to have different levels of fatigue. Individuals with more functional abilities reported less fatigue (p< 0.002) and those with higher pain reported higher fatigue (p< 0.001). The FISSA was shown to have adequate test-retest reliability, ICC(3,1)=0.74 (95% CI 0.53-0.87).
