A pilot study of home-based genetic testing completion rate in telegenetics cancer clinics in West Virginia Appalachia

Telegenetics has shifted some genetic testing performance to the patient's own home, with the patient collecting his/her own sample. Little is known regarding the rate of test completion of such home-based genetic testing. This study compared the completion rate of home-based genetic tests before and after a reminder system was implemented. In the pre-reminder group, we reviewed medical records for patients who were seen via telegenetics and agreed to complete genetic testing using an at-home test kit. In the reminder group, a prospective analysis of the genetic test completion rate was performed taking a clinical quality improvement approach where three reminders were provided for patients who had not submitted their at-home genetic testing. Our study included 94 patients' records: 46 pre-reminders and 48 reminders. The lab received 24 patient samples (52.2%) in the pre-reminder group. In the reminder group, 30 patients returned their kits (62.5%). Despite a higher percentage of patients completing their test in the reminder group, there was no statistically significant difference between the pre-reminder and reminder groups. The rate of test completion in our pilot test was statistically similar between the two groups, but the reminder group was trending toward a higher percent of completion which may be clinically meaningful.     

Persistence of effects of nitric oxide synthase inhibitors: Comparisons on blood flow and plasma exudation in guinea pig skin

Use of pluronic micelles to overcome multidrug-resistance

Pluronic P-85 (poly(55)(oxypropylene)dipoly(s)(oxyethylene)) was used to form daunorubicin containing micelles. This new carrier was tested in vitro on sensitive and resistant ovarian cancer cell lines. Drug incorporation was measured by cytofluorometry and the cytotoxicity was measured by the tetrazolium formazan XTT assay. ID50 of 0.16 and 25 mu g/ml were obtained for conjugated and free daunorubicin respectively. The results obtained suggest that this approach may be used in combination with a chemotherapeutic agent to overcome multidrug resistance.     

Risk factors for HIV-1 seroconversion among injection drug users: a case-control study.

OBJECTIVES. A nested case-control study was conducted in Miami, Fla, to determine risk factors associated with human immunodeficiency virus type 1 (HIV-1) seroconversion among injection drug users. METHODS. The study identified 21 incident cases of HIV-1 infection and 76 unmatched controls from two longitudinal cohorts of injection drug users. One cohort consisted of individuals who originally had been recruited from treatment centers; a second cohort was recruited from the "street." Logistic regression analyses that adjusted for age, gender, and race were performed. RESULTS. The final model determined that the primary independent risk factor that best explained the risk for seroconversion was sharing injection equipment in the year prior to conversion; a marginal risk factor was presence of sexually transmitted disease during this same period. CONCLUSIONS. Both an injection component and a sexual component play a role in seroconversion among injection drug users, although the injection component is much stronger.     

Child Abuse: Imaging Findings Pertaining to the Musculoskeletal System

Both underrecognized and underreported, child abuse has a spectrum of findings on imaging of the musculoskeletal structures that may permit the radiologist to first suggest the occurrence of child abuse or to help support clinical concern for a diagnosis of child abuse. This article will discuss the approach to imaging of the musculoskeletal system in suspected child abuse, illustrate many of the more common imaging findings, and present imaging pitfalls and alternative diagnostic considerations. Injuries to the brain, spinal cord, gastrointestinal and genitourinary systems, and cardiopulmonary structures are outside the scope of this article.
