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
Cancer patient preferences for communication of prognosis in the metastatic setting
PURPOSE: To identify preferences for and predictors of prognostic information among patients with incurable metastatic cancer. PATIENTS AND METHODS: One hundred twenty-six metastatic cancer patients seeing 30 oncologists at 12 outpatient clinics in New South Wales, Australia, participated in the study. Patients were diagnosed with incurable metastatic disease within 6 weeks to 6 months of recruitment. Patients completed a survey eliciting their preferences for prognostic information, including type, quantity, mode, and timing of presentation; anxiety and depression levels; and information and involvement preferences. RESULTS: More than 95% of patients wanted information about side effects, symptoms, and treatment options. The majority wanted to know longest survival time with treatment (85%), 5-year survival rates (80%), and average survival (81%). Words and numbers were preferred over pie charts or graphs. Fifty-nine percent (59%) wanted to discuss expected survival when first diagnosed with metastatic disease. Thirty-eight percent and 44% wanted to negotiate when expected survival and dying, respectively, were discussed. Patients with higher depression scores were more likely to want to know shortest time to live without treatment (P = .047) and average survival (P = .049). Lower depression levels were significantly associated with never wanting to discuss expected survival (P = .03). Patients with an expected survival of years were more likely to want to discuss life expectancy when first diagnosed with metastases (P = .02). CONCLUSION: Most metastatic cancer patients want detailed prognostic information but prefer to negotiate the extent, format, and timing of the information they receive from their oncologists.<br /
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

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.Version of Recor
Travel-Associated Zika Virus Disease Acquired in the Americas Through February 2016
BACKGROUND: Zika virus has spread rapidly in the Americas and has been imported into many nonendemic countries by travelers.
OBJECTIVE: To describe clinical manifestations and epidemiology of Zika virus disease in travelers exposed in the Americas.
DESIGN: Descriptive, using GeoSentinel records. SETTING: 63 travel and tropical medicine clinics in 30 countries.
PATIENTS: Ill returned travelers with a confirmed, probable, or clinically suspected diagnosis of Zika virus disease seen between January 2013 and 29 February 2016.
MEASUREMENTS: Frequencies of demographic, trip, and clinical characteristics and complications.
RESULTS: Starting in May 2015, 93 cases of Zika virus disease were reported. Common symptoms included exanthema (88%), fever (76%), and arthralgia (72%). Fifty-nine percent of patients were exposed in South America; 71% were diagnosed in Europe. Case status was established most commonly by polymerase chain reaction (PCR) testing of blood and less often by PCR testing of other body fluids or serology and plaque-reduction neutralization testing. Two patients developed Guillain–Barre syndrome, and 3 of 4 pregnancies had adverse outcomes (microcephaly, major fetal neurologic abnormalities, and intrauterine fetal death).
LIMITATION: Surveillance data collected by specialized clinics may not be representative of all ill returned travelers, and denominator data are unavailable.
CONCLUSION: These surveillance data help characterize the clinical manifestations and adverse outcomes of Zika virus disease among travelers infected in the Americas and show a need for global standardization of diagnostic testing. The serious fetal complications observed in this study highlight the importance of travel advisories and prevention measures for pregnant women and their partners. Travelers are sentinels for global Zika virus circulation and may facilitate further transmission
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
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
