An Update on Screening and Prevention for Breast and Gynecological Cancers in Average and High Risk Individuals.

Breast and gynecological cancers affect almost 900,000 women and therefore most health care providers will be involved at some point in the management of women with cancer. As the prognosis of all cancers is much more favorable when diagnosed in early stages, it is imperative that all health care providers are familiar not only with current screening guidelines for the average population, but also with the identification of high risk individuals who may benefit from more intense screening as well as available interventions to prevent disease or decrease risk. The purpose of this review article is to provide relevant information to physicians and other health care providers to aid in identifying patients that are classified as "high risk" for developing breast or a gynecologic cancer, outlining what interventions exist for adequate screening and risk reduction strategies, and to provide an update on current screening guidelines for individuals at average and high risk.

Individual and combined effects of low dissolved oxygen and low pH on survival of early stage larval blue crabs, Callinectes sapidus.

A large number of coastal ecosystems globally are subjected to concurrent hypoxic and acidified conditions that will likely intensify and expand with continued climate change. In temperate regions, the spawning of many important organisms including the Atlantic blue crab Callinectes sapidus occurs during the summer months when the severity of coastal hypoxia and acidification is the greatest. While the blue crab earliest larval stage can be exposed to co-occurring hypoxia and acidification observed in many coastal ecosystems, the effects of these concurrent stressors on larval blue crab survival is unknown.

Transcriptomic Responses in the Bloom-Forming Cyanobacterium Microcystis Induced during Exposure to Zooplankton.

The bloom-forming, toxic cyanobacterium synthesizes multiple secondary metabolites and has been shown to deter zooplankton grazing. However, the biochemical and/or molecular basis by which deters zooplankton remains unclear. This global transcriptomic study explored the response of to direct and indirect exposures to multiple densities of two cladoceran grazers, and Higher densities of both daphnids significantly reduced cell densities and elicited a stronger transcriptional response in While many putative grazer deterrence genes (encoding microcystin, aeruginosin, cyanopeptolin, and microviridin) were largely unaffected by zooplankton, transcripts for heat shock proteins () increased in abundance.

Cochlear trajectory in pediatric patients.

Objectives/hypothesis: As cochlear implantation increases, surgeons are noting possible anatomical differences in pediatric population. Outcome objectives were to study pediatric temporal bone anatomy using high-resolution temporal bone imaging, and analyze the anatomical differences in group 1 (<12 months) versus group 2 (1-4 years) versus group 3 (5-10 years) versus group 4 (10-18 years).

Study Design: Retrospective chart and radiologic review.

Contrast media in breast imaging.

Although mammography is the standard imaging modality for detection of breast cancer, magnetic resonance (MR) imaging is a valuable adjunct and, in certain cases, is the imaging of choice. Contrast-enhanced breast MR imaging provides a noninvasive means of staging disease, assessing posttreatment response, and screening of high-risk patients with genetic predispositions. Additional indications for MR mammography include lesion characterization, contralateral breast evaluation in patients with proved malignancy, and identifying primary malignancy in patients with axillary nodal disease.
