Different disparities of gender and race among the thrombotic thrombocytopenic purpura and hemolytic-uremic syndromes

Thrombotic thrombocytopenic purpura (TTP) and hemolytic-uremic syndrome (HUS) represent multiple disorders with diverse etiologies. We compared the gender and race of 335 patients enrolled in the Oklahoma TTP-HUS Registry across 21 years for their first episode of TTP or HUS to appropriate control groups. The relative frequency of women and white race among patients with TTP-HUS-associated with a bloody diarrhea prodrome and the relative frequency of women with quinine-associated TTP-HUS were significantly greater than their control populations. The relative frequency of women and black race among patients with idiopathic TTP and TTP-associated with severe ADAMTS13 deficiency was significantly greater than their control populations. The relative frequency of black race among patients who had systemic lupus erythematosus (SLE) preceding TTP was significantly greater than among a population of patients with SLE, and the relative frequency of black race among patients with other autoimmune disorders preceding TTP was significantly greater than their control population. No significant gender or race disparities were present among patients with hematopoietic stem cell transplantation-associated thrombotic microangiopathy, TTP associated with pregnancy, or TTP associated with drugs other than quinine. The validity of these observations is supported by the enrollment of all consecutive patients across 21 years from a defined geographic region, without selection or referral bias. These observations of different gender and race disparities among the TTP-HUS syndromes suggest the presence of different risk factors and may serve as starting points for novel investigations of pathogenesis.

Posttraumatic growth in cancer patients and partners--effects of role, gender and the dyad on couples' posttraumatic growth experience

Little is known about factors influencing positive effects in couples facing a cancer diagnosis.

Culture's Calling: Mobile Phones, Gender, and the Making of an African Migrant Village in Lisbon

In this article, I explore how immigrants from the West African nation of Guinea-Bissau living in Portugal use mobile phones in their daily lives in Lisbon. Whereas one might assume that mobile phones and other new information technologies facilitate transnational communication between Africa and Portugal, the ethnographic fieldwork that I conducted in Lisbon from 1999 to 2003 revealed a different scenario. Instead, mobile phones as imagined and used by the Guinean immigrants I met in Lisbon revealed less about transnationalism and globalization than they did about constructing community and identity in a new locale. As Guinean immigrants in Portugal reconfigured their relationship to their former colonizers and struggled to make their way in a new, multicultural Europe, they used their mobile phones to engage local networks, shape local identities, and transform Lisbon's sprawl into an African migrant village. Here, I highlight the gendered dimensions of this process and contend that Guinean men's and women's varied uses of mobile phones in Lisbon underscore contrasting experiences of migration, mobility, and belonging.

Yolk Androstenedione in Domestic Chicks (Gallus Gallus Domesticus): Uptake and Sex-Dependent Alteration of Growth and Behavior

In birds, causes and consequences of variation in maternally-derived steroids in egg yolk have been the subject of intense experimentation. Many studies have quantified or manipulated testosterone ("T") and one of its immediate precursors, androstenedione ("A4") - often lumping the two steroids as "androgens" and treating them as functionally equivalent. However, yolk A4 is deposited in substantially higher concentrations than T, binds only weakly to the androgen receptor, and is readily converted into either T or estrone by steroidogenic enzymes present during embryonic development. Thus it may not be appropriate to assume that A4 has the same effect as T. In addition, A4's metabolic fate is likely to differ between females and males. The goals of this study were to examine the sex-specific uptake and metabolism of yolk A4 and consequences of elevated levels of yolk A4 on development and behavior of domestic chicks. Eggs were injected with 2mu Ci of tritiated androstenedione; radioactivity was detected in all tissues of day 7 and day 16 embryos and found in both aqueous and organics phases of day 7 yolk, with no difference between sexes. A second set of eggs was injected with 125ng of A4. A4 increased growth of morphological traits (tarsus, beak) in females, but not males. A4 males had smaller combs than controls; there was no treatment effect in females. A4 reduced tonic immobility behavior in both sexes. The results of this study illustrate the importance of distinguishing both between androgens and between sexes when investigating avian endocrine maternal effects. Copyright 2013 Elsevier Inc.

Expanding Women's Worlds?: Development, Gender, and Environment in Rural Morocco

This honors thesis is an anthropological exploration of women's cooperatives in two regions of rural Morocco. Specifically, I am interested in how contemporary development projects such as the cooperative are understood by the peoples of these regions. By conducting first-hand ethnographic research among women's cooperatives in two drastically different environments of rural Morocco, I gain further insight into the roles that culture and geography play in determining the 'success' of cooperatives inlocal communities. In using the term 'success,' I will compare notions of success as used by both Western development organizations as well as local people in Morocco. I examine and analyze the very delicate and complex interaction that occurs between largely Western development agencies and local cultures particularly through the lens of gender. I will also convey the importance of an exchange of cultural practices through development projects rather than the imposition of one cultural system on another. In writing this thesis, I hope to contribute to the growing field of the anthropologyof development, a subset of cultural anthropology that examines international development practices and the economic, social, and political factors that have an impact on the local culture. I examine cooperatives from the perspectives of both the people whoparticipate in them through personal interviews as well as development institutions through an ongoing body of published literature. Focusing on gender implications that such development initiatives have on the rural cultures of Morocco, I argue that gender identities are crucial aspects of local cultures that must be addressed within development practices. On a broader scale, I argue that a deeper knowledge of local cultures is essential if development agencies are to be 'successful' in non-Western cultures.
