PurposeTo analyze the potential association between social support, experiences of violence, and sociodemographic characteristics of adolescents and the likelihood of acceptance of violence and machismo in different European countries.MethodsCross-sectional design. We recruited 1,555 participants ages 13–16 from secondary schools in Alicante (Spain), Rome (Italy), Iasi (Romania), Matosinhos (Portugal), Poznan (Poland), and Cardiff (UK). We used linear regression models to identify how social support from teachers and parents, experiences of violence—dating violence, bullying, cyberbullying, abuse in childhood—and sociodemographic characteristics were associated with violent thinking, specifically: machismo and acceptance of violence. The analysis was stratified by sex.ResultsAcceptance of violence was higher for those who had lower perceived social support from parents (βgirls = ?154, p < .001; βboys = ?.114, p = .019) for both sexes. Perpetration of bullying and/or cyberbullying was associated with higher scores for machismo and acceptance of violence for both sexes (βgirls = .067, p = .035; βboys = .225, p < .001; (βgirls = .118, p < .001; βboys = .210, p < .001). Being the victim of dating violence, having suffered physical and/or sexual abuse in childhood, and lower perceived social support from teachers were associated with higher scores for both machismo and acceptance of violence. These associations differed between girls and boys.ConclusionsMachismo and acceptance of violence are widely present amongst adolescents in different European countries. Our results suggest the importance of providing educational/psycho-educational interventions with boys and girls to prevent these attitudes and, in turn, prevent interpersonal violence, including bullying and dating violence. 相似文献
Vascular lesions are commonly encountered in routine pathologic practice and often pose diagnostic challenges owing to their morphologic diversity. Although WT-1 expression was reported in some vascular tumors, little is known about its staining patterns in a spectrum of vascular lesions from various locations. We examined WT-1 immunostain in 95 cases of vascular lesions including angiosarcomas (AS, 19 cases), hemangioendotheliomas (HE, 5), Kaposi’s sarcomas (KS, 4), cavernous hemangiomas (CVH, 12), capillary hemangiomas (CPH, 7), pyogenic granulomas (PG, 4), lymphangiomas (LA, 4), hemangiopericytomas (HP, 5), glomus tumors (GT, 8), vascular malformation (VM, 13) and granulation tissue (GRT, 14). Strong WT-1 cytoplasmic stain was invariably observed in all cases of malignant and borderline vascular tumors including AS (19/19), KS (4/4) and HE (5/5). WT-1 was also consistently expressed in CPH (7/7), PG (4/4), and GRT (14/14), while it became weaker in VM (10/13) and often negative in CVH (2/12) and LA (0/4). WT1 stain was not demonstrated in HP (0/5) and rarely in GT (2/8). We conclude that consistent and diffuse WT-1 cytoplasmic stain in AS, HE and KS can be useful in distinguishing these tumors from poorly differentiated tumors with mimicking features. On the other hand, reliable WT-1 stain in CPH, PG and GRT may help in differential diagnosis with non-endothelial vascular tumors such as GT and HP. Recognizing the WT-1 cytoplasmic stain in a broad spectrum of benign and neoplastic tissues is critical in formulating appropriate immunohistochemical panels and avoiding misinterpretation of results. 相似文献
The effectiveness of the utensil swab test as part of the periodic inspection of food establishments was studied both as an indicator of cleanliness during the period between inspections and as an educational tool. Two to seven samplings were taken at intervals of two to three months at 95 food establishments in rural areas in the northern part of Israel. A statistical analysis showed a high variation and almost no correlation between repeated samplings of the same establishment. Also, no trend to suggest an educational effect was found. We concluded that, though the swab test had proved to be useful in special projects, it had no value as part of the periodic sanitary inspections. 相似文献
AbstractSarcoidosis is a chronic, multisystem noncaseating granulomatous disease of unknown etiology. Sarcoidosis typically presents clinically in individuals between the ages of 20 and 40 years. Although sarcoidosis most commonly affects the respiratory system, nearly any organ system can be involved. Spinal cord involvement by sarcoidosis is a rare event, occurring in less than 1% of patients with systemic disease. The case presented is that of a 29-year-old black male with benign past medical history who presented with a 6-week history of progressive incomplete paraplegia arid bowel dysfunction. Magnetic resonance imaging revealed an intramedullary mass at the T-4-T-5 levels. The patient underwent thoracic laminectomy and debulking of the mass. The pathology was consistent with granulomatous disease. Postoperatively, the patient was placed on prednisone. He subsequently received comprehensive inpatient and outpatient rehabilitation and at present is bowel and bladder continent and ambulating at community levels with a rolling walker. The diagnosis of sarcoidosis; potential treatment options, including debulking and long-term steroid use; and prognosis will be discussed. 相似文献
Introduction: Mitochondrial-derived peptides (MDPs) are encoded within the mitochondrial genome. They signal within the cell or are released to act as autocrine/paracrine/endocrine cytoprotective factors playing a key role in the cellular stress response. The first reported and better characterized MDP is humanin (HN), which exerts robust protective effects against a myriad of cytotoxic stimuli in many cell types. These effects have led to the evaluation of HN and its analogs as therapeutic targets for several chronic diseases.
Areas covered: We describe the latest findings on the mechanism of action of HN and discuss the role of HN as therapeutic target for neurodegenerative and cardiovascular diseases, diabetes, male infertility, and cancer. Since HN can be detected in circulation, we also depict its value as a biomarker for these diseases.
Expert opinion: HN analogs and peptide mimetics have been developed over the last decade and show promising results in preclinical models of degenerative diseases. Local administration of gene therapy vectors that overexpress or silence endogenous HN could also hold therapeutic potential. Controversy on the role of HN in cancer progression and chemoresistance should be addressed before the translation of these therapeutic approaches. 相似文献
