Psychopathy in violent female offenders in Finland

BACKGROUND: The base rate and construct of psychopathy in violent female offenders were examined. SAMPLING AND METHODS: More than half of all violent female offenders in Finland who where either hospitalised (n=12) or incarcerated (n=46) during the year of the study were assessed by the Hare Psychopathy Checklist-Revised (PCL-R), Structured Clinical Interview II for DSM-IV, Beck Anxiety Inventory, Beck Depression Inventory-II and Wechsler Adult Intelligence Scale-Revised. RESULTS: PCL-R mean scores and a base rate of psychopathy were found to be in line with earlier studies, showing both lower values and prevalence in females. The PCL-R correlated with symptoms of cluster B personality disorders as well as with depressive personality disorder. Factor 2 was observed to positively correlate with anxiety and depression and negatively with verbal cognitive ability. Logistic regression analysis on the PCL-R items revealed that the items shallow affect, lack of remorse or guilt, conning/manipulation and lack of realistic goals seem to be important indicators of female psychopathy together with callous/lack of empathy, impulsivity and failure to accept responsibility for own actions. CONCLUSION: The finding indicates that the prevalence of psychopathy is lower among female offenders than among male offenders, but further research is needed to examine the base rate of psychopathy in women, and whether the symptoms of psychopathy are expressed differently in women than in men.     

Urokinase, tissue-type plasminogen activator and plasminogen activator inhibitor-1 expression in severely stenosed and occluded vein grafts with thrombosis.

Intimal hyperplasia and subsequent thrombotic occlusions limit the success of vascular reconstructive procedures. Plasminogen activation in situ may be an important factor affecting re-stenosis of the graft. Tissue specimens from eight patients with failing or failed infra-inguinal vein bypasses and three specimens from normal veins were harvested to study urokinase-type plasminogen activator (u-PA), tissue-type plasminogen activator (t-PA) and plasminogen activator inhibitor-1 (PAI-1) by in situ hybridization and immunohistochemistry. The possible presence of thrombi was monitored by platelet and fibrin-specific stainings. In occluded grafts, platelet endothelial cell adhesion molecule (PECAM-1) antibody stained the thrombi but not the endothelial area, indicating the absence of endothelium. Platelet glycoprotein (GP) IIb/IIIa co-localized with PECAM-1 and, furthermore, GP IIb/IIIa staining was positive on the vein walls with thrombi and to some extent in the grafts without thrombi. PAI-1 and u-PA were uniformly upregulated in intimal thickening in grafts without thrombus. In organized thrombi, enhanced u-PA, t-PA and PAI-1 reactivity was detected in the ingrowing subendothelium. In non-occluded grafts with small thrombi, u-PA expression was enriched beneath microthrombi co-localizing with the graft wall injury, while PAI-1 was scattered in the (sub)endothelium. We conclude that fibrinolytic system is upregulated at sites of graft stenosis, and local proteolytic degradation of the graft wall associates with thrombus formation.     

Culture of retinal pigment epithelial cells from subretinal fluid

Culture of cells from subretinal fluid (SRF) was performed using 29 SRF samples obtained at retinal reattachment surgery. Proliferating cells were found in 58.6% of the samples studied. The cells were of retinal pigment epithelial (RPE) origin, as evidenced by their brown pigmentation in primary culture and their positive immunostaining for cytokeratins 8/18. The age of the patients did not affect the proliferative capacity of the cells. Proliferating cells were present in all samples from eyes with proliferative vitreoretinopathy (PVR) of grade C1 or more. In primary culture the cells had a fibroblast-like morphology, resembling that of ordinary RPE cells exposed to the vitreous. We conclude that the SRF of many patients with PVR contains viable proliferating RPE cells and that SRF offers a new source of RPE cells for studies on the pathogenesis of PVR.     

Factors associated with intimate partner violence by a former partner by immigration status and length of residence in Canada

PurposeWe examined intimate partner violence (IPV) by a former partner among Canadian-born and immigrant women by length of residence in Canada.MethodsData from a 2009 national, population-based, telephone survey were used to determine the prevalence of and factors associated with any type of IPV (emotional, financial, physical, and/or sexual) by a former partner with whom there had been contact in the previous 5 years among immigrant women 0 to 19 years in Canada, 20 or more years or longer in Canada, and Canadian-born women (n = 1681).ResultsOf immigrant women in Canada for 0 to 19 years, 41.6% had experienced IPV by a former partner; for immigrant women in Canada for 20 or more years or longer, 60.6%, and Canadian-born women, 61.5% (P = .0423). In a logistic regression model adjusted for age and other sociodemographic characteristics, immigrant women in Canada for 0 to 19 years were less likely than Canadian-born women to experience any IPV (odds ratio, 0.266; 95% confidence interval, 0.130–0.544). There was no difference in the occurrence of any IPV between immigrant women in Canada 20 or more years or longer and Canadian-born women.ConclusionsHigh rates of any IPV by a former partner were found for both Canadian-born and immigrant women. Within immigrant communities, specific prevention campaigns should address the high risk of experiencing IPV at later stages of resettlement.     

Acute central nervous system complications in varicella zoster virus infections.

BACKGROUND: In a previous multicenter study on central nervous system (CNS) viral infections varicella zoster virus (VZV) appeared the most frequent etiologic agent and appeared often without rash. OBJECTIVE: To evaluate the appearance and diagnostics of VZV in CNS more thoroughly, we studied the cases systematically by using sensitive and specific methods to learn the best diagnostic approach in order to start specific therapy. STUDY DESIGN: We analyzed all serum and cerebrospinal fluid samples of 174 patients, 88 females and 86 males, with acute CNS symptoms associated with VZV infection diagnosed in the multicenter study on viral CNS infections. RESULTS: About 38 patients (22%) had chickenpox, 59 (34%) had shingles, and 77 (44%) had no cutaneous symptoms at all. The mean age of chickenpox patients was 8.6 years, of the others 46.6 and 41.4 years. VZV-specific nucleic acid was detected in the CSF in one fourth of the patients in all groups, primarily during the first week of illness. In serum specimens, specific IgM was present in two thirds of the patients with chickenpox, whereas in the others in one third of the cases. In CSF, specific IgM was present in 15-17% of patients with skin manifestations, compared with 6% of those without rash. CONCLUSIONS: The role of VZV infections in CNS complications seems remarkable, often presenting without rash. Even these cases should be promptly recognized in order to conduct proper antiviral therapy. In children, a combination of PCR and IgM tests is the best approach. In adults, PCR, together with the measurement of intrathecal antibody production yields best results.     

Differential effects of acute and chronic wound fluids on urokinase-type plasminogen activator, urokinase-type plasminogen activator receptor, and tissue-type plasminogen activator in cultured human keratinocytes and fibroblasts

The effect of wound fluids collected from acute well-healing wounds and chronic nonhealing venous leg ulcers on the plasminogen activation system of keratinocyte and fibroblast cell cultures was studied in a simplified wound-healing model. Acute wound fluid was collected from donor sites of split skin grafts at different time points representing the progressive healing of the wound. Urokinase-type plasminogen activator, tissue-type plasminogen activator, urokinase-type plasminogen activator receptor, and plasminogen activator inhibitor 1 expression were studied. The methods used were immunocapture assay and immunocytochemistry. The results indicated that the later the acute wound fluid was collected, the greater the urokinase-type plasminogen activator and the lower the plasminogen inhibitor-1 level in treated cells. In contrast, the level of urokinase-type plasminogen activator receptor remained stable irrespective of wound fluid treatment. Immunostaining for urokinase-type plasminogen activator of acute wound fluid-treated cells showed a disseminated punctate pattern over the cell surface, but with chronic wound fluid, urokinase-type plasminogen activator was localized to focal contacts. Our findings support the view that in the acute wound environment the plasminogen activator system is proteolytically active and that in chronic leg ulcers urokinase-type plasminogen activator and urokinase-type plasminogen activator receptor may also be organized for cell adhesion and migration.
