The use of granulocyte colony-stimulating factor (G-CSF)-mobilized peripheral blood as a source of stem cells has resulted in a high incidence of severe chronic graft-versus-host disease (cGVHD), which compromises the outcome of clinical allogeneic stem cell transplantation. We have studied the effect of G-CSF on both immune complex and fibrotic cGVHD directed to major (DBA/2 --> B6D2F1) or minor (B10.D2 --> BALB/c) histocompatibility antigens. In both models, donor pretreatment with G-CSF reduced cGVHD mortality in association with type 2 differentiation. However, after escalation of the donor T-cell dose, scleroderma occurred in 90% of the recipients of grafts from G-CSF-treated donors. In contrast, only 11% of the recipients of control grafts developed scleroderma, and the severity of hepatic cGVHD was also reduced. Mixing studies confirmed that in the presence of high donor T-cell doses, the severity of scleroderma was determined by the non-T-cell fraction of grafts from G-CSF-treated donors. These data confirm that the induction of cGVHD after donor treatment with G-CSF is dependent on the transfer of large numbers of donor T cells in conjunction with a putatively expanded myeloid lineage, providing a further rationale for the limitation of cell dose in allogeneic stem cell transplantation.

The cytokine, tumour necrosis factor-alpha (TNF-alpha) plays a key role in the pathogenesis of many chronic inflammatory and rheumatic diseases, in particular, Crohn's disease, rheumatoid arthritis, ankylosing spondylitis and psoriatic arthritis. Controlled trials have shown that the TNF inhibitors (etanercept, infliximab and adalimumab) significantly reduce symptoms and signs, improve function and quality of life, and reduce radiologically evident damage in patients with rheumatoid diseases. For reasons that are not entirely clear, etanercept does not work in Crohn's disease. Injection site and intravenous reactions and increased risk of infection (in particular, reactivation of tuberculosis) are associated with the use of these agents. Increased risk of lymphoproliferative disease, the development of lupus-like syndromes and demyelination, including optic neuritis and reactivation of multiple sclerosis, are under evaluation in long-term follow-up studies. The TNF inhibitors are expensive (about $18000 per year), and in some patients need to be given continuously to maintain benefit, even in the presence of other immunosuppressive therapy.

A practical Bayesian approach for inference in neural network models has been available for ten years, and yet it is not used frequently in medical applications. In this chapter we show how both regularisation and feature selection can bring significant benefits in diagnostic tasks through two case studies: heart arrhythmia classification based on ECG data and the prognosis of lupus. In the first of these, the number of variables was reduced by two thirds without significantly affecting performance, while in the second, only the Bayesian models had an acceptable accuracy. In both tasks, neural networks outperformed other pattern recognition approaches.

Sexual harassment at work is a form of gender violence barely made visible but still present in labor organizations, where it keeps generating high levels of suffering, discrimination and inequality mainly affecting women. To address it properly it is necessary an organizational change towards equity arising from the knowledge of the subjective meanings that stakeholders (staff, union representatives, employers, public administration, etc.) attribute to that reality. In this article we present the main findings of a qualitative study on the social perception of sexual harassment. The work highlights the existence of many strategies aimed at legitimize and minimize the relevance of the problem, blaming the victim, justifying the lack of support from the environment and / or the involvement of the organization in the solutions. Among the conclusions we underline the need for new models of business management involving all stakeholders in the prevention and control of the in a responsible way.

Varios estudios tanto retrospectivos como prospectivos han encontrado una fuerte asociación entre los anticuerpos antifosfolípidos y la trombosis arterial y/o venosa, y a la condición sistémica caracterizada por éstos elementos clínicos y autoinmunes se le ha reconocido como síndrome antifosfolípidos. A diferencia de los casos adultos, los datos sobre el síndrome antifosfolípidos pediátrico son escasos. No existe ningún estudio en los niños salvadoreños con éste síndrome. Objetivos: especificar las características clínicas, epidemiológicas e inmunológicas de los pacientes con síndrome antifosfolípidos del Hospital Nacional de Niños Benjamín Bloom en el período de Enero 2009 a Diciembre 2013. Métodos: se realizó una investigación descriptiva, retrospectiva de corte transversal, que detalló a través del uso del instrumento del Ped APS Registry los aspectos clínicos, demográficos e inmunológicos de los casos de síndrome antifosfolípidos pediátrico. Se revisaron retrospectivamente 14 casos de SAF pediátrico del Hospital Bloom, 11 asociados a lupus eritematos sistémico, 1 asociado a PTI y 2 primarios. Se determinó información sociodemográfica, trastornos trombóticos, hematológicos, dermatológicos, renales, cardiovasculares y neurológicos. Las características inmunológicas detalladas fueron la presencia de anticuerpos IgG e IgM anticardiolipinas, anticoagulante lúpico, anticuerpos antinucleares, anticuerpos anti ds- DNA, complementos C3 y C4. Resultados: el estudio incluyó 14 pacientes, 10 pacientes femeninas y 4 masculinos. La mayoría de los casos de SAF fueron secundarios a LES. El evento trombótico más frecuente fue la trombosis venosa, en su mayoría de miembros inferiores. La característica no trombótica más frecuente fue la afección hematológica y renal. El estudio de las características inmunológicas se vio limitado por la falta de datos en gran parte de los casos estudiados. Conclusiones: los datos de éste estudio conforman la primera investigación de las características de SAF pediátrico en el Centro de Referencia Pediátrica de El Salvador, y ofrecen una aproximación al comportamiento de éste síndrome. Los resultados obtenidos son acordes a lo determinado en literatura mundial. Sin embargo, son necesarios estudios con mayor cantidad de pacientes y con perfil inmunológico completo de los pacientes.
