Common genetic risk for melanoma encourages preventive behavior change.

There is currently great interest in using genetic risk estimates for common disease in personalized healthcare. Here we assess melanoma risk-related preventive behavioral change in the context of the Coriell Personalized Medicine Collaborative (CPMC). As part of on-going reporting activities within the project, participants received a personalized risk assessment including information related to their own self-reported family history of melanoma and a genetic risk variant showing a moderate effect size (1.7, 3.0 respectively for heterozygous and homozygous individuals). Participants who opted to view their report were sent an optional outcome survey assessing risk perception and behavioral change in the months that followed. Participants that report family history risk, genetic risk, or both risk factors for melanoma were significantly more likely to increase skin cancer preventive behaviors when compared to participants with neither risk factor (ORs = 2.04, 2.79, 4.06 and p-values = 0.02, 2.86 × 10-5, 4.67 × 10-5, respectively), and we found the relationship between risk information and behavior to be partially mediated by anxiety. Genomic risk assessments appear to encourage positive behavioral change in a manner that is complementary to family history risk information and therefore may represent a useful addition to standard of care for melanoma prevention.

Conference Scene: Personalized medicine: changing the healthcare paradigm.

The US Air Force Patient-Centered Precision Care Genomic Medicine Research Program hosted a symposium entitled 'Changing the Health Care Paradigm' on 27 September 2011 in Laurel, MD, USA. The program provided a unique opportunity for subject matter experts to participate in critical discussions on the current and potential outlook for the implementation of genome-informed healthcare. The implications for patient privacy, data management and security revealed the ethical, legal and social issues faced by clinicians, patients and policy-makers. Highlights from these discussions are summarized in this article.

Enteric disease surveillance under the AFHSC-GEIS: current efforts, landscape analysis and vision forward.

The mission of the Armed Forces Health Surveillance Center, Division of Global Emerging Infections Surveillance and Response System (AFHSC-GEIS) is to support global public health and to counter infectious disease threats to the United States Armed Forces, including newly identified agents or those increasing in incidence. Enteric diseases are a growing threat to U.S. forces, which must be ready to deploy to austere environments where the risk of exposure to enteropathogens may be significant and where routine prevention efforts may be impractical. In this report, the authors review the recent activities of AFHSC-GEIS partner laboratories in regards to enteric disease surveillance, prevention and response. Each partner identified recent accomplishments, including support for regional networks. AFHSC/GEIS partners also completed a Strengths, Weaknesses, Opportunities and Threats (SWOT) survey as part of a landscape analysis of global enteric surveillance efforts. The current strengths of this network include excellent laboratory infrastructure, equipment and personnel that provide the opportunity for high-quality epidemiological studies and test platforms for point-of-care diagnostics. Weaknesses include inconsistent guidance and a splintered reporting system that hampers the comparison of data across regions or longitudinally. The newly chartered Enterics Surveillance Steering Committee (ESSC) is intended to provide clear mission guidance, a structured project review process, and central data management and analysis in support of rationally directed enteric disease surveillance efforts.

Screening for syphilis infection in pregnant women: evidence for the U.S. Preventive Services Task Force reaffirmation recommendation statement.

BACKGROUND: In 2004, the U.S. Preventive Services Task Force strongly recommended that clinicians screen all pregnant women for syphilis infection. PURPOSE: To update the evidence on screening pregnant women for syphilis infection. DATA SOURCES: MEDLINE searches from 1 January 2003 through 31 July 2008, recent systematic reviews, reference lists of retrieved articles, and expert suggestions. STUDY SELECTION: English-language studies were selected to answer the following 2 questions: Does screening for syphilis in pregnancy reduce the prevalence of congenital syphilis in neonates? Are there harms of screening for syphilis or harms of treatment with penicillin in pregnancy to women or neonates? Randomized, controlled trials; meta-analyses; systematic reviews; cohort studies; and ecologic studies were selected for the potential benefits question. Randomized, controlled trials; meta-analyses; systematic reviews; cohort studies; case-control studies; and large case series were selected for the potential harms question. DATA EXTRACTION: Information on the study design, selection criteria, demographic characteristics, and clinical outcomes was extracted from each study. DATA SYNTHESIS: One study on benefits evaluated the effect before and after the implementation of a universal syphilis screening program for pregnant women and found reductions in rates of congenital syphilis. Two studies on screening accuracy for syphilis reported false-positive rates of less than 1%. One study that used a large insurance claims database reported an incidence of anaphylaxis after oral penicillin of 0.1 per 10,000 dispensings. In a study from Hungary, oral penicillin in pregnancy was not associated with orofacial clefts. LIMITATIONS: This was a targeted literature search and could have missed small studies on the benefits and harms of screening for syphilis in pregnancy. We did not review evidence on interventions to improve rates of prenatal screening. CONCLUSION: New evidence from a study of universal screening supports previous evidence on the effectiveness of screening for syphilis in pregnancy to prevent congenital syphilis. Harms include testing and follow-up for false-positive test results and adverse effects from penicillin treatment.
