SensiScreen®KRAS exon 2-sensitive simplex and multiplex real-time PCR-based assays for detection of KRAS exon 2 mutations.

Activating mutations in codon 12 and codon 13 of the KRAS (Kirsten rat sarcoma viral oncogene homolog) gene are implicated in the development of several human cancer types and influence their clinical evaluation, treatment and prognosis. Numerous different methods for KRAS genotyping are currently available displaying a wide range of sensitivities, time to answer and requirements for laboratory equipment and user skills. Here we present SensiScreen® KRAS exon 2 simplex and multiplex CE IVD assays, that use a novel real-time PCR-based method for KRAS mutation detection based on PentaBase's proprietary DNA analogue technology and designed to work on standard real-time PCR instruments.

Are good intentions good enough? Informed consent without trained interpreters.

Objective: To examine the informed consent process when trained language interpreters are unavailable.

Background: Ensuring sufficient patient understanding for informed consent is especially challenging for patients with Limited English Proficiency (LEP). While US law requires provision of competent translation for LEP patients, such services are commonly unavailable.

On the processing of proghrelin to ghrelin.

The orexigenic hormone ghrelin is a 28-amino-acid peptide derived from a 99-amino-acid precursor and acylated at Ser-3, which was initially isolated from rat stomach. In addition to stimulating appetite and growth, it also plays various important roles in energy homeostasis and in the cardiovascular and immune systems. Although analysis of its physiological effects has yielded many significant results, much less information is available on its biosynthesis and the mechanism of its acylation.

Do notions of risk inform patient choice? Lessons from a study of prenatal genetic counseling.

Risk modeling is an increasingly important part of clinical medicine; however, "risk status" is a complex notion, understood differently by patients and clinicians. Patients' ability to make informed choices about clinical procedures often requires that they interpret risk statistics, which may be difficult to understand and apply. In this article, which is based on a study of prenatal care in South Texas, we consider how notions of risk affect patient decisions about prenatal genetic testing.

Clinical myths of the cultural "other": implications for Latino patient care.

Purpose: Cultural competency is now a requirement in the curriculum of many health professions. However, clinicians' understandings of cultural difference, the accuracy of those understandings, and their impact on patient care have not yet been carefully explored. The authors conducted an ethnographic study designed to describe clinicians' views of Latino culture in the context of amniocentesis decision making, compared those to patients' discussions of their decision making, and explored how clinicians' views about culture are manifested in consultations with Latinas.
