Stressful events during last year, violence and anxiety and depression: A moderated mediation model by sex
he literature suggests that being subject to a stressful life and victimization may negatively affect mental health, and that women and men seem to differ in these variables. Nevertheless, neither the mediating role of victimization experiences in the relationship between stress and mental health, nor the moderated role of sex have been explored. A sample of 826 adults, aged from 18 to 77 years old, completed a set of self-reported questionnaires (69.4% women). Results revealed significant mediation effects of psychological violence on the relationship between stress, depression and anxiety. Participants who reported more stressful life events in the previous year, also reported higher psychological abuse, which in turn predicted higher depression and anxiety. Furthermore, the moderating effects of sex were found to be statistically significant. Results suggest that interventions should be tailored to individual needs in order to prevent secondary victimization derived from biased beliefs related to stress, violence and gender in professional practice.info:eu-repo/semantics/acceptedVersio
When subjective social status matters: moderating effects in the association between victimization and mental health
Social status is found to interfere with health outcomes after adverse life experiences. Evidence suggests the importance of subjective social status (SSS), above and beyond objective status. This study tests the moderating role of SSS in the association between victimization and mental health, considering the effect of distinct forms of victimization, clinical symptoms and psychological well-being. A sample of 300 adults completed self-reported questionnaires. Results revealed that greater psychological victimization was associated with lower self-acceptance and autonomy, and greater sexual victimization was associated with lower autonomy, particularly when participants reported lower SSS. Implications for intervention with victims are discussed.info:eu-repo/semantics/acceptedVersio

Institutional Impact of EVAR's Incorporation in the Treatment of Abdominal Aortic Aneurysm: a 12 Years' Experience Analysis
Introduction:
Endovascular aneurysm repair (EVAR) was introduced as a less aggressive treatment of abdominal aortic aneurysms (AAA) for patients ineligible for open repair (OR).
Objective:
To analyze EVAR's incorporation impact in the treatment of infra-renal abdominal aortic aneurysms in our institution.
Methods:
A retrospective study of the patients with diagnostic of infra-renal AAA treated between December 2001 and December 2013 was performed. The choice between EVAR and OR was based on surgeon's experience, considering patient clinical risk and aneurysm's anatomical features. Patients treated by EVAR and by OR were analyzed. In each group, patient's and aneurysm's characteristics, surgical and anesthesia times, cost, transfusion rate, intraoperative complications, hospital stay, mortality and re-intervention rates and survival curves were evaluated.
Results:
The mean age, all forms of heart disease and chronic renal failure were more common in EVAR group. Blood transfusion, surgical and anesthesia times and mean hospital stay were higher for OR. Intraoperative complications rate was higher for endovascular aneurysm repair, overall during hospitalization complication rate was higher for open repair. The average cost in endovascular aneurysm repair was 1448.3€ higher. Re-interventions rates within 30 days and late re-intervention were 4.1% and 11.7% for endovascular aneurysm repair versus 13.7% and 10.6% for open repair.
Conclusions:
Two different groups were treated by two different techniques. The individualized treatment choice allows to achieve a mortality of 2.7%. Age ≥80 years influences survival curve in OR group and ASA ≥IV in EVAR group. We believe EVAR's incorporation improved the results of OR itself. Patients with more comorbidities were treated by endovascular aneurysm repair, decreasing those excluded from treatment. Late reinterventions were similar for both techniques.info:eu-repo/semantics/publishedVersio
Predicting the critical density of topological defects in O(N) scalar field theories
O(N) symmetric field theories describe many critical
phenomena in the laboratory and in the early Universe. Given N and ,
the dimension of space, these models exhibit topological defect classical
solutions that in some cases fully determine their critical behavior. For N=2,
D=3 it has been observed that the defect density is seemingly a universal
quantity at T_c. We prove this conjecture and show how to predict its value
based on the universal critical exponents of the field theory. Analogously, for
general N and D we predict the universal critical densities of domain walls and
monopoles, for which no detailed thermodynamic study exists. This procedure can
also be inverted, producing an algorithm for generating typical defect networks
at criticality, in contrast to the canonical procedure, which applies only in
the unphysical limit of infinite temperature.Comment: 4 pages, 3 figures, uses RevTex, typos in Eq.(11) and (14) correcte

Changes induced by malathion, methylparathion and parathion on membrane lipid physicochemical properties correlate with their toxicity
Perturbations induced by malathion, methylparathion and parathion on the physicochemical properties of dipalmitoylphosphatidylcholine (DPPC) were studied by fluorescence anisotropy of DPH and DPH-PA and by differential scanning calorimetry (DSC). Methylparathion and parathion (50 [mu]M) increased the fluorescence anisotropy evaluated by DPH-PA and DPH, either in gel or in the fluid phase of DPPC bilayers, but mainly in the fluid phase. Parathion is more effective than methylparathion. On the other hand, malathion had almost no effect. All the three xenobiotics displaced the phase transition midpoint to lower temperature values and broadened the phase transition profile of DPPC, the effectiveness following the sequence: parathion>methylparathion>>malathion. A shifting and broadening of the phase transition was also observed by DSC. Furthermore, at methylparathion/lipid molar ratio of 1/2 and at parathion/lipid molar ratio of 1/7, the DSC thermograms displayed a shoulder in the main peak, in the low temperature side, suggesting coexistence of phases. For higher ratios, the phase transition profile becomes sharp as the control transition, but the midpoint is shifted to the previous shoulder position. Conversely to methylparathion and parathion, malathion did not promote phase separation. The overall data from fluorescence anisotropy and calorimetry indicate that the degree of effect of the insecticides on the physicochemical membrane properties correlates with toxicity to mammals. Therefore, the in vivo effects of organophosphorus compounds may be in part related with their ability to perturb the phospholipid bilayer structure, whose integrity is essential for normal cell function.http://www.sciencedirect.com/science/article/B6T1T-42NY32W-K/1/9c5c8320a8dff42bbf122281b5056b8
