Childhood Sexual Abuse and Substance Abuse In Female Inmates
This study examined the relationship of childhood sexual abuse and substance abuse in female jail inmates residing in a Multnomah County Correctional facility. Consistent with prior research, this population was found lo be emotionally, mentally and socioeconomically disadvantaged. Specifically, the results of this study are compatible with previous studies which show the effects of childhood sexual abuse to involve a higher rate of substance use and other antisocial behaviors including promiscuity and prostitution. One-hundred and six (53.2%) respondents reported a history of childhood sexual abuse. This finding is higher than recent National Justice Bureau of Statistics surveys which found that 37 .2% of female inmates had ever been sexually abused. Seventy four (68.9%) of the childhood sexual abuse victims were significantly more likely to use crack cocaine. 35.8% (38) were more likely to have traded sex for drugs. and 47. l % (50) were more likely to have traded sex for money. In addition, a significant number of childhood sexual abuse victims (98.1 % = 104) reported to have used alcohol. The need for program development with focus on treatment of substance abuse and trauma co-occurance is addressed
Power, Cloth and Currency on the Loango Coast
Cloth was a basic resource for the peoples of the Loango Coast throughout their precolonial history. It was used in
daily life for furnishings and for clothing; it was essential in landmark events such as initiation and burial ceremonies; it was
part of key transactions that cemented lineage and state alliances; and it served as a currency. The importation of European cloth from the sixteenth century began a transition from indigenous, domestically produced cloth to a reliance on
foreign cloth, but cloth maintained its significance as a key resource at all levels of society. Access to sources of cloth
and control of its distribution were closely associated with the wielding of power, whether by royal administrators, lineage
elders, religious specialists or merchant-brokers
The External Trade of the Loango Coast and Its Effects on the Vili 1576-1870.
The Loango Coast is a useful term to describe the West African Coast which lies between Cape Lopez in the north and the Congo River in the south. In the sixteenth century, the region was divided into three kingdoms, Loango, Kakongo and Ngoyo. This study discusses two interrelated themes. The first concerns the changing patterns of external trade; here, four main phases may be differentiated. The first was a pre-slave trade period, from about 1576 to 1630 when indigenous African commercial activities expanded under the impetus of European contact; between 1630 and 1670 the products of legitimate trade decreased in importance and the trade in slaves gained momentum; the years from 1670 to 1793 have been called the Slave Trade Era; from about 1793 to 1870, the slave traders faced mounting problems until their activities were finally ended and a legitimate trade was reestablished. The second theme deals specifically with the Vili kingdom of Loango, which, as the term "Loango Coast" implies, dominated the region until its fortunes changed in the eighteenth century. The discussion suggests how the Vili were affected by the changing patterns of external trade. Chapters 1 and 8 are primarily concerned with this subject, although it is also touched on at various other points. The Maloango and the traditional aristocracy, who dominated the sixteenth aid seventeenth century Vili kingdom, were forced to share power witha class of nouveaux- riches thrown up by the slave trade, by the late eighteenth century. The final demise of the old kingdom occurred in the nineteenth century, when the order and unity of traditional society was lost amid the unstable conditions brought by the rule of petty chiefs. The last chapter attempts to show that these changes were a positive response to varying circumstances, not mere decay
Inflammation in benign prostate tissue and prostate cancer in the finasteride arm of the Prostate Cancer Prevention Trial
BACKGROUND: A previous analysis of the placebo arm of the Prostate Cancer Prevention Trial (PCPT) reported 82% overall prevalence of intraprostatic inflammation and identified a link between inflammation and higher-grade prostate cancer and serum PSA. Here we studied these associations in the PCPT finasteride arm. METHODS: Prostate cancer cases (N=197) detected either on a clinically indicated biopsy or on protocol-directed end-of-study biopsy, and frequency-matched controls (N=248) with no cancer on an end-of-study biopsy were sampled from the finasteride arm. Inflammation in benign prostate tissue was visually assessed using digital images of H&E stained sections. Logistic regression was used for statistical analysis. RESULTS: In the finasteride arm, 91.6% of prostate cancer cases and 92.4% of controls had at least one biopsy core with inflammation in benign areas; p < 0.001 for difference compared to placebo arm. Overall, the odds of prostate cancer did not differ by prevalence (OR=0.90, 95% CI 0.44-1.84) or extent (P-trend=0.68) of inflammation. Inflammation was not associated with higher-grade disease (prevalence: OR=1.07, 95% CI 0.43-2.69). Furthermore, mean PSA concentration did not differ by the prevalence or extent of inflammationin either cases or controls. CONCLUSION: The prevalence of intraprostatic inflammation was higher in the finasteride than placebo arm of the PCPT, with no association with higher-grade prostate cancer. IMPACT: Finasteride may attenuate the association between inflammation and higher-grade prostate cancer. Moreover, the missing link between intraprostatic inflammation and PSA suggests that finasteride may reduce inflammation-associated PSA elevation

Association of Regional Variation in Primary Care Physicians’ Colorectal Cancer Screening Recommendations with Individual Use of Colorectal Cancer Screening
Introduction: Studies show that the recommendations of a primary care physician for colorectal cancer screening may be one important influence on an individual's use of screening. However, another possible influence, the effect of regional differences in physicians' beliefs and recommendations on screening use, has not been assessed. Methods: We linked data from the National Health Interview Survey on the use of colorectal cancer screening by respondents aged 50 years or older, by hospital-referral region, with data from the Survey of Colorectal Cancer Screening Practices on the colorectal cancer screening recommendations of primary care physicians, by region. Our principal independent variables were the proportion of physicians in a region who recommended screening at age 50 and continuing screening at the recommended frequency. Results: On average, 53.3% of physicians in a region correctly recommended initiating colorectal cancer screening, and 64.8% advised screening at the recommended frequency. Of adults who lived in regions where less than 30% of physicians correctly recommended initiating screening, 47.3% had been screened, in contrast to 54.8% in areas where 70% or more of physicians made correct recommendations. Seventy-one percent of respondents living in regions where less than 30% of physicians advised screening at the recommended frequency were current on screening, in contrast to 79.9% of respondents living in regions where 70% or more of physicians made this recommendation. These differences were statistically significant after adjustment for individual characteristics. Conclusion: Strategies to improve colorectal cancer screening recommendations of primary care physicians may improve the use of screening for millions of Americans
Urban football narratives and the colonial process in Lourenço Marques
Support for Portuguese football teams, in Mozambique as well as in other former
Portuguese colonies, could be interpreted either as a sign of the importance of a
cultural colonial heritage in Africa or as a symbol of a perverse and neo-colonial
acculturation. This article, focused on Maputo, the capital of Mozambique –
formerly called Lourenc¸o Marques – argues that in order to understand
contemporary social bonds, it is crucial to research the connection between the
colonial process of urbanisation and the rise of urban popular cultures. Despite
the existence of social discrimination in colonial Lourenc¸o Marques, deeply
present in the spatial organisation of a city divided between a ‘concrete’ centre
and the immense periphery, the consumption of football, as part of an emergent
popular culture, crossed segregation lines. I argue that football narratives, locally
appropriated, became the basis of daily social rituals and encounters, an element
of urban sociability and the content of increasingly larger social networks.
Therefore, the fact that a Portuguese narrative emerged as the dominant form of
popular culture is deeply connected to the growth of an urban community
Chandra X-Ray Observatory Observations of the Globular Cluster M71
We observed the nearby, low-density globular cluster M71 (NGC 6838) with the
Chandra X-ray Observatory to study its faint X-ray populations. Five X-ray
sources were found inside the cluster core radius, including the known
eclipsing binary millisecond pulsar (MSP) PSR J1953+1846A. The X-ray light
curve of the source coincident with this MSP shows marginal evidence for
periodicity at the binary period of 4.2 h. Its hard X-ray spectrum and
luminosity resemble those of other eclipsing binary MSPs in 47 Tuc, suggesting
a similar shock origin of the X-ray emission. A further 24 X-ray sources were
found within the half-mass radius, reaching to a limiting luminosity of 1.5
10^30 erg/s (0.3-8 keV). From a radial distribution analysis, we find that
18+/-6 of these 29 sources are associated with M71, somewhat more than
predicted, and that 11+/-6 are background sources, both galactic and
extragalactic. M71 appears to have more X-ray sources between L_X=10^30--10^31
erg/s than expected by extrapolating from other studied clusters using either
mass or collision frequency. We explore the spectra and variability of these
sources, and describe the results of ground-based optical counterpart searches.Comment: 36 pages including 7 figures and 8 tables, accepted by The

A Summary of the Endocrine Society Clinical Practice Guidelines on Congenital Adrenal Hyperplasia due to Steroid 21-Hydroxylase Deficiency
Steroid 21-hydroxylase deficiency accounts for about 95% of cases of congenital adrenal hyperplasia (CAH). Newborns are currently being screened for the classical forms of this disease throughout the United States and in 12 other countries. As such, it seems important to develop the best practice guidelines for treating not only infants and children, but affected adults as well. This report gives a brief overview of the most recent expert opinion and clinical practice guidelines for CAH as formulated by The Endocrine Society Task Force
The two-faced T cell epitope: Examining the host-microbe interface with JanusMatrix
Advances in the field of T cell immunology have contributed to the understanding that cross-reactivity is an intrinsic characteristic of the T cell receptor (TCR), and that each TCR can potentially interact with many different T cell epitopes. To better define the potential for TCR cross-reactivity between epitopes derived from the human genome, the human microbiome, and human pathogens, we developed a new immunoinformatics tool, JanusMatrix, that represents an extension of the validated T cell epitope mapping tool, EpiMatrix. Initial explorations, summarized in this synopsis, have uncovered what appear to be important differences in the TCR cross-reactivity of selected regulatory and effector T cell epitopes with other epitopes in the human genome, human microbiome, and selected human pathogens. In addition to exploring the T cell epitope relationships between human self, commensal and pathogen, JanusMatrix may also be useful to explore some aspects of heterologous immunity and to examine T cell epitope relatedness between pathogens to which humans are exposed (Dengue serotypes, or HCV and Influenza, for example). In Hand-Foot-Mouth disease (HFMD) for example, extensive enterovirus and human microbiome cross-reactivity (and limited cross-reactivity with the human genome) seemingly predicts immunodominance. In contrast, more extensive cross-reactivity with proteins contained in the human genome as compared to the human microbiome was observed for selected Treg epitopes. While it may be impossible to predict all immune response influences, the availability of sequence data from the human genome, the human microbiome, and an array of human pathogens and vaccines has made computationally–driven exploration of the effects of T cell epitope cross-reactivity now possible. This is the first description of JanusMatrix, an algorithm that assesses TCR cross-reactivity that may contribute to a means of predicting the phenotype of T cells responding to selected T cell epitopes. Whether used for explorations of T cell phenotype or for evaluating cross-conservation between related viral strains at the TCR face of viral epitopes, further JanusMatrix studies may contribute to developing safer, more effective vaccines
