Hormone replacement therapy and stroke
Stroke is the third most common cause of death in women and a major cause of disability. Stroke occurs in older age in women compared with men. High premenopausal estrogen concentrations in women are thought to be protective against stroke and cardiovascular disease. Estrogens are essential for normal reproductive function and they exert complex and diverse non reproductive actions on multiple tissues such as neuroprotective effects, vasodilatation, improved vascular reactivity, antithrombotic effects and lipid lowering effects. After menopause estrogen concentrations are depleted and in the past estrogen replacement therapy was considered as a potential protective agent against both cardiovascular disease and stroke. Although the use of hormone therapy was originally associated with a reduction in the risk of heart disease by about 50% in observational studies, the results regarding stroke have been less clear. In order to investigate the effect of hormone therapy on stroke risk, randomized controlled trials of cardio-and/or cerebrovascular-disease prevention in women with established heart disease have been designed. The Heart Estrogen-Progestin Replacement Study included stroke as secondary outcome. This study did not show any differences in myocardial infarction (MI) or coronary death (HR 0.99; 95%CI 0.80-1.22) and in stroke rate. In another study, the Women Estrogen Stroke Trial, 17 beta estradiol 1 mg/placebo was administered to women with previous ischemic stroke or transient ischaemic attack (TIA) having a mean age 71. No differences in stroke rate (RR 1.1; 95% CI 0.8-1.4) and in mortality rate (RR 1.2; 95% CI 0.8-1.8) were found, while a trend showing an increased rate of fatal strokes (RR 2.9; 95% CI 0.9-9.0) and for more severe non-fatal strokes (% patients with final National Institutes of Health Stroke Scale (NIHSS) 0-1: 19 % vs. 33%; p = 0.12) was observed. The Women's Health Initiative, a primary prevention study, where conjugated equine estrogen (CEE) plus medroxyprogesterone acetate/placebo was utilized, was stopped because of an excess in breast cancer and increased stroke rates (RR 1.4; 95% CI 1.1-1.8). Recently, a meta-analysis including 39,769 women participating in 28 trials has been published. Twelve studies were of secondary prevention and the overall stroke rate was 2%. In the hormone replacement therapy (HRT) arm there was a 29% increased rate of ischemic stroke (Number Needed to Harm, NNH:147). Furthermore, a 56% increased rate of death or dependency after stroke and a tendency of more fatal stroke were observed. Additionally, a higher stroke risk was reported in the first year of treatment.
Conclusions: There seems to be no indication for hormone replacement therapy in the prevention of stroke in women. Further studies are needed to discover why estrogens have different effects on the heart and brain. Conventional risk-factors which could increase the risk of estrogen therapy need to be identified and as well as more restrictive inclusion and exclusion criteria such as coagulation parameters and intimal thickness should be adopted before new randomized trials are started.Stroke is the third most common cause of death in women and a major cause of disability.

Effect of on-admission antiplatelet treatment on patients with cerebral hemorrhage
Background: Antiplatelet treatment remains the first choice for primary and secondary prevention of vascular diseases; even so, expected benefits may be offset by risk of bleeding, particularly cerebral hemorrhage. The aim of this study was to assess the influence of antiplatelet treatment on clinical outcome at hospital discharge.
Materials and methods: Consecutive patients with first-ever stroke due to a primary intraparenchymal hemorrhage were prospectively identified over a 4-year period (2000-2003). Data on hemorrhage location, vascular risk factors, and antiplatelet and anticoagulant treatment were collected. At discharge, outcome was measured using the modified Rankin Scale (disabling stroke > or =3). Patients treated with anticoagulant therapy were excluded from the study.
Results: Of 457 consecutive patients with cerebral hemorrhage, 94 (20.5%) had been taking antiplatelet agents. The treated patients (mean age for antiplatelet group 78.9 +/- 9.0 years) were older than the nontreated patients (73.8 +/- 9.4, p = 0.02). In-hospital mortality was 23.4 and 23.1% (p = n.s.) for patients who had been taking antiplatelet agents or no treatment. Poor outcome at discharge was found in 52.1 and 59.7% (p = n.s.), respectively. Univariate analysis showed that age and coma at admission were predictors of disability at discharge, but antiplatelet treatment was not. Additionally, age and coma were shown to be determinants of disability at discharge after multivariate analysis: OR 1.03 per year (95% CI: 1.018-1.049), p < 0.001 and OR 1.68 (95% CI: 1.138-2.503), p = 0.009, respectively.
Conclusions: Hemorrhagic stroke continues to be responsible for a high percentage of disability and death. Furthermore, it was seen here that functional outcome was independent of previous antiplatelet treatment.Background: Antiplatelet treatment remains the first choice for primary and secondary prevention of vascular diseases; even so, expected benefits may be offset by risk of bleeding, particularly cerebral hemorrhage.

I Think I Am Philip K. Dick
For years, noted writer Laurence A. Rickels often found himself compared to novelist Philip K. Dickthough in fact Rickels had never read any of the science fiction writers work. When he finally read his first Philip K. Dick novel, while researching for his recent book The Devil Notebooks , it prompted a prolonged immersion in Dicks writing as well as a recognition of Rickelss own long-documented intellectual pursuits. The result of this engagement is I Think I Am: Philip K. Dick , a profound thought experiment that charts the wide relevance of the pulp sci-fi author and paranoid visionary. I Think I Am: Philip K. Dick explores the science fiction authors meditations on psychic reality and psychosis, Christian mysticism, Eastern religion, and modern spiritualism. Covering all of Dicks science fiction, Rickels corrects the lack of scholarly interest in the legendary Californian author and, ultimately, makes a compelling case for the philosophical and psychoanalytic significance of Philip K. Dicks popular and influential science fiction.Intro -- Contents -- Introjection -- Part I -- Endopsychic Allegories -- Schreber Guardian -- Belief System Surveillance -- Part II -- Deeper Problems -- Veil of Tears -- Go West -- Dick Manfred -- Timing -- Glimmung -- Part III -- Spiritualism Analogy -- Imitating the Dead -- Indexical Layer -- Ilse -- Hammers and Things -- Crucifictions -- Over There -- Martyrology -- Can't Live, Can't Live -- Lola -- Umwelt, Mitwelt, and Eigenwelt -- Outer Race -- The German Introject -- Part IV -- Materialism, Idealism, and Cybernetics -- Startling Stories -- A Couple of Years -- Android Empathy -- Homunculus and Robot -- ALL OF YOU ARE DEAD.

The AM Canum Venaticorum binary SDSS J173047.59+554518.5
The AM Canum Venaticorum (AM CVn) binaries are a rare group of hydrogen-deficient, ultrashort period, mass-transferring white dwarf binaries and are possible progenitors of Type Ia supernovae. We present time-resolved spectroscopy of the recently discovered AM CVn binary SDSS J173047.59+554518.5. The average spectrum shows strong double-peaked helium emission lines, as well as a variety of metal lines, including neon; this is the second detection of neon in an AM CVn binary, after the much brighter system GP Com. We detect no calcium in the accretion disc, a puzzling feature that has been noted in many of the longer period AM CVn binaries. We measure an orbital period, from the radial velocities of the emission lines, of 35.2 ± 0.2 min, confirming the ultracompact binary nature of the system. The emission lines seen in SDSS J1730 are very narrow, although double-peaked, implying a low-inclination, face-on accretion disc; using the measured velocities of the line peaks, we estimate i ≤ 11°. This low inclination makes SDSS J1730 an excellent system for the identification of emission lines
Freedom of choice or force of circumstance? : Eastern European sex-workers in the Republic of Cyprus ; paper for the conference 'Alltag der Globalisierung. Perspektiven einer transnationalen Anthropologie', January 16-18, 2003, Institute of Cultural Anthropology and European Ethnology, Johann Wolfgang Goethe University, Frankfurt am Main
This paper focuses on Eastern European migrants who, since the beginning of the 1990s, are entering the Republic Cyprus as “artistes”. This is a visa permit status as well as an euphemism for short-term work permits in the local sex industry. In addition to exploring the migrational experiences of these women and their living and working conditions in the Republic of Cyprus, the paper reconstructs, empirically and analyt ically, the connection between immigration and the local sex industry. Here, several categories of social actors and institutions in Cyprus are actively involved. The rhetoric of government representatives, entrepreneurs and clients in the sex business on the one hand is contrasted with the discourse of local NGO representatives concerned with immigrants’ rights on the other hand. The paper comes to the conclusion that all of these discursive positions ultimately do not do justice to the complex process of decisionmaking that women undergo who migrate into the sex industry. Either, freedom of choice is emphasized – such as by entrepreneurs and the government – or the domination of women – as in the public statements of the NGO. In order to analyze the ambivalent tension between freedom of choice and submission to force by which the women’s decision is characterized, the author employs Michel Foucault’s concept of governmentality, which describes forms of political regulation that use the individual’s freedom of action as an instrument to exercise power

An examination of author characteristics in national and regional criminology and criminal justice journals, 2008-2010: Are female scholars changing the nature of publishing in criminology and criminal justice?
Criminology and criminal justice (CCJ) as an academic discipline has experienced an increase in the focus on various aspects of academic productivity in recent years. Much of the extant literature examining journal article authorship has focused on various measures of the publication productivity of specific authors but not on the characteristics of the authors themselves. The current study expands upon previous work by examining several author characteristics across different journal types and research methodologies, with a particular focus on how gender relates to these issues. The findings reveal several interesting differences with regard to gender, academic rank, and university affiliation. Among these findings is evidence that although males are more likely to author CCJ articles regardless of journal type, females are more likely to be lead authors in regional journal articles and more likely to publish with other female authors. Regional journals are also the publication outlet of choice for students and assistant professors in the beginning of their careers. The findings also provide evidence of important differences in author rank, academic affiliation, methodology, and publication outlet for articles authored by females.Journal ArticlePublishe
