Trial Design and Objectives for Castration-Resistant Prostate Cancer: Updated Recommendations From the Prostate Cancer Clinical Trials Working Group 3

Abstract: PurposeEvolving treatments, disease phenotypes, and biology, together with a changing drug development environment, have created the need to revise castration-resistant prostate cancer (CRPC) clinical trial recommendations to succeed those from prior Prostate Cancer Clinical Trials Working Groups.MethodsAn international expert committee of prostate cancer clinical investigators (the Prostate Cancer Clinical Trials Working Group 3 [PCWG3]) was reconvened and expanded and met in 2012-2015 to formulate updated criteria on the basis of emerging trial data and validation studies of the Prostate Cancer Clinical Trials Working Group 2 recommendations.ResultsPCWG3 recommends that baseline patient assessment include tumor histology, detailed records of prior systemic treatments and responses, and a detailed reporting of disease subtypes based on an anatomic pattern of metastatic spread. New recommendations for trial outcome measures include the time to event end point of symptomatic skeletal events, as well as tim...

Recovering the feminine other: masculinity, femininity, and gender hegemony

Abstract: R. W. Connell’s path-breaking notion of multiple masculinities (Connell, 1995) and hegemonic masculinity (Connell, 1987, 1995) have been taken up as central constructs in the sociology of gender. Although there has been a great deal of empirical research and theory published that has built upon and utilized Connell’s concepts, an adequate conceptualization of hegemonic femininity and multiple femininities has not yet been developed. To redress this, the author presents a theoretical framework that builds upon the insights of Connell and others, offers a definition of hegemonic masculinity and hegemonic femininity that allows for multiple configurations within each, and that can be used empirically across settings and groups. The author also outlines how hegemonic masculinity and hegemonic femininity are implicated in and intersect with other systems of inequality such as class, race, and ethnicity.

Identification of a subpopulation of rapidly self-renewing and multipotential adult stem cells in colonies of human marrow stromal cells.

Abstract: Marrow stromal cells are adult stem cells from bone marrow that can differentiate into multiple nonhematopoietic cell lineages. Previous reports demonstrated that single-cell-derived colonies of marrow stromal cells contained two morphologically distinct cell types: spindle-shaped cells and large flat cells. Here we found that early colonies also contain a third kind of cell: very small round cells that rapidly self-renew. Samples enriched for the small cells had a greater potential for multipotential differentiation than samples enriched for the large cells. Also, the small cells expressed a series of surface epitopes and other proteins that potentially can be used to distinguish the small cells from the large cells. The results suggested it will be important to distinguish the major subpopulations of marrow stromal cells in defining their biology and their potential for cell and gene therapy.

Childhood cardiovascular risk factors and carotid vascular changes in adulthood: the Bogalusa Heart Study.

Abstract: ContextCarotid artery intima-media thickness (IMT) is associated with cardiovascular risk factors and is recognized as an important predictive measure of clinical coronary atherosclerosis events in middle-aged and elderly populations. However, information on the association of carotid IMT in young adults with different risk factors measured in childhood, adulthood, or as a cumulative burden of each of the risk factors measured serially from childhood to adulthood is limited.ObjectiveTo examine the association between carotid IMT in young adults and traditional cardiovascular risk factors measured since childhood.Design, Setting, and ParticipantsA cohort study of 486 adults aged 25 to 37 years from a semirural black and white community in Bogalusa, La (71% white, 39% men), who had at least 3 measurements of traditional risk factors since childhood, conducted between September 1973 and December 1996.Main Outcome MeasureAssociation of carotid IMT with risk factors, including systolic blood pressure, lipoprotein levels, and body mass index.ResultsMale vs female (0.757 mm vs 0.719 mm) and black vs white (0.760 mm vs 0.723 mm) participants had increased carotid IMT (P<.001 for both). In multivariable analyses, significant predictors for being in top vs lower 3 quartiles of carotid IMT in young adults were childhood measures of low-density lipoprotein cholesterol (LDL-C) level (odds ratio [OR], 1.42, corresponding to 1-SD change specific for age, race, and sex; 95% confidence interval [CI], 1.14-1.78) and body mass index (BMI; OR, 1.25; 95% CI, 1.01-1.54); adulthood measures of LDL-C level (OR, 1.46; 95% CI, 1.16-1.82), high-density lipoprotein cholesterol (HDL-C) level (OR, 0.67; 95% CI, 0.51-0.88), and systolic blood pressure (OR, 1.36; 95% CI, 1.08-1.72); and long-term cumulative burden of LDL-C (OR, 1.58; 95% CI, 1.24-2.01) and HDL-C (OR, 0.75; 95% CI, 0.58-0.97) levels measured serially from childhood to adulthood. An increasing trend in carotid IMT across quartiles of LDL-C level measured in childhood was observed, with a mean value of 0.761 mm (95% CI, 0.743-0.780 mm) for those at the top quartile vs 0.724 mm (95% CI, 0.715-0.734 mm) for those in the lower 3 quartiles (P<.001).ConclusionsChildhood measures of LDL-C level and BMI predict carotid IMT in young adults. The prevention implications of these findings remains to be explored.
