Acetabular morphology variations in a Hispanic population.

BACKGROUND: Rotational abnormalities of the hip have been implicated in the etiology of diseases, such as hip dysplasia, osteoarthritis, and femoroacetabular impingement. Despite the extensive literature on hip morphology, there is a gap in knowledge regarding variations in the Hispanic population. PURPOSE: To describe the bony anatomy variations of the acetabulum in a Hispanic population. MATERIAL AND METHODS: This is a cross-sectional study. We studied 182 computed tomography (CT) images in patients aged older than 21 years, who had undergone pelvic CT for any condition, except hip fracture. Measurements of acetabular version, anterior and posterior acetabular sector angles (AASA/PASA) and horizontal acetabular sector angles (HASA) were made. Acetabular variations were then compared to weight and sex data. RESULTS: The mean acetabular anteversion was greater in women (P < 0.001). Women exhibited a greater PASA (P < 0.05); however, men had a greater AASA (P < 0.05). Underweight individuals had a smaller PASA (P < 0.01) and HASA (P < 0.05) than individuals with a normal weight. CONCLUSION: The Hispanic hip is morphologically similar to other populations previously reported in the literature; however, Hispanic men have less coverage of the femoral head by the posterior acetabular wall when compared to women of the same ethnicity. These abnormalities have a direct impact on management and surgical approach in patients treated for femoroacetabular impingement and hip dysplasia.

The ethics of nursing care for transgender people.

OBJECTIVES: to discuss ethical aspects in nursing care for transgender people. METHODS: reflective study based on the dilemmas that emerges in nursing care for transgender people. The report was structured around the four bioethical principles. RESULTS: health care for trans people is complex, transversal to many devices and specialties and longitudinal in time, that is why it requires coordinated action. There is an ethical framework in which the nursing care must be observed in the care of this group. FINAL CONSIDERATIONS: the nurse as a health worker can assume several general lines in the care of transgender patients. So, complementary training should be provided not only to professionals, but also to students of nursing and other health sciences.

RESUMO Objetivos: discutir aspectos éticos na assistência de enfermagem às pessoas transgênero. Métodos: estudo reflexivo a partir dos dilemas que surgem no cuidado de enfermagem às pessoas transgênero. O relato foi estruturado em torno dos quatro princípios bioéticos. Resultados: a atenção à saúde de pessoas trans é complexa, transversal a muitos dispositivos e especialidades e longitudinal no tempo, por isso requer ação coordenada. Existe um referencial ético no qual se enquadram os cuidados de enfermagem que devem ser observados no atendimento a esse grupo. Considerações Finais: o enfermeiro como agente de saúde pode assumir diversas linhas gerais no atendimento a pacientes transgênero. Para tal, deve ser proporcionada formação complementar não só aos profissionais, mas também aos estudantes de enfermagem e outras ciências da saúde.

RESUMEN Objetivos: debatir sobre aspectos éticos en la atención de enfermería a personas transgénero. Métodos: estudio reflexivo fundamentado sobre los dilemas que se plantean en los cuidados de enfermería a personas transgénero. El relato se ha estructurado en torno a los cuatro principios bioéticos. Resultados: la atención sanitaria a las personas trans es compleja, transversal a muchos dispositivos y especialidades y longitudinal en el tiempo por lo que precisa de la actuación coordinada. Existe un marco ético en el que se encuadran los cuidados de enfermería que se precisan en la atención a este colectivo. Consideraciones Finales: la enfermera como agente de salud puede asumir diversas líneas generales en la atención a pacientes transgénero. Para ello, se debe brindar formación adicional no solo a los profesionales, también a los estudiantes de enfermería y de las demás ciencias de la salud.

Semen promotes the differentiation of tolerogenic dendritic cells.

Seminal plasma is not just a carrier for spermatozoa. It contains high concentrations of cytokines, chemokines, and other biological compounds that are able to exert potent effects on the immune system of the receptive partner. Previous studies have shown that semen induces an acute inflammatory response at the female genital mucosa after coitus. Moreover, it induces regulatory mechanisms that allow the fetus (a semiallograft) to grow and develop in the uterus. The mechanisms underlying these regulatory mechanisms, however, are poorly understood. In this study, we show that seminal plasma redirects the differentiation of human dendritic cells (DCs) toward a regulatory profile. DCs differentiated from human monocytes in the presence of high dilutions of seminal plasma did not express CD1a but showed high levels of CD14. They were unable to develop a fully mature phenotype in response to LPS, TNF-α, CD40L, Pam2CSK4 (TLR2/6 agonist), or Pam3CSK4 (TLR1/2 agonist). Upon activation, they produced low amounts of the inflammatory cytokines IL-12p70, IL-1ß, TNF-α, and IL-6, but expressed a high ability to produce IL-10 and TGF-ß. Inhibition of the PG receptors E-prostanoid receptors 2 and 4 prevented the tolerogenic effect induced by seminal plasma on the phenotype and function of DCs, suggesting that E-series PGs play a major role. By promoting a tolerogenic profile in DCs, seminal plasma might favor fertility, but might also compromise the capacity of the receptive partner to mount an effective immune response against sexually transmitted pathogens.
