Islam Bogotá: presencia inicial y diversidad

El texto se centra en el estudio de las comunidades musulmanas de Bogotá. Como tal, se hace referencia a las tendencias de pensamiento religioso que las distinguen dentro de la diversidad existente en el Mundo Islámico, pero especialmente se hace énfasis en sus actividades, prácticas cotidianas, formas de organización y relación con el entorno social de la ciudad. El trabajo es fruto del estudio realizado por la Línea de Historia y Estudio Comparado de las Religiones del Centro de Estudios Teológicos y de las Religiones de la Universidad del Rosario, entre los musulmanes de la ciudad durante los años 2007 - 2008. El texto, que se dirige a un público amplio, no especializado en el tema, ofrece una base introductoria al Islam como hecho religioso, social y cultural, así como a la manera en la que los musulmanes viven su cotidianidad, con el fin de preparar a los lectores para comprender de manera adecuada los pormenores del estudio realizado. Así mismo, se enmarca el fenómeno de las comunidades musulmanas en la ciudad dentro de una traducción histórica, pero también dentro de unos ejes de influencia que los relacionan con otras regiones del mundo y del continente.

Duelo, ansiedad y depresión en familiares de pacientes en una unidad de cuidados paliativos a los dos meses de la pérdida

Aim: This study is going to assess the prevalance of prolonged grief diagnoses and it will evaluate the severity of the symptoms of depression, anxiety and complicated grief two months after a loved one is lost. We also intend to study which variables associated with the risk of grief could be more decisive when diagnosing it, its symptoms and the consequent emotional distress.Method: A total of 66 families of patients in the Palliative Care Unit (PCU) at Hospital San Cecilio in Granada have been evaluated. Measurements were taken two months after the death. This investigation has explored the existing emotional distress using the following questionnaires: Beck Depression Inventory (BDI-II), Beck Anxiety Inventory (BAI), Inventory of Complicated Grief (ICG) and Prolongued Grief Disorder (PG-12).Results: The results show that 33.3% and 21.21% of the sufferers had high levels of depression and clinical anxiety two months after the death. The prevalence of prolongued grief diagnoses, according to the PG-12, is 10.6% and 53.03% of the participants showed symptoms of complicated grief according to the ICG. Additionally, statistically significant differences are found in the sufferers with and without a prolongued grief diagnosis and scores in the ICG and BDI-II. The family’s financial situation is linked to the presence of symptoms of anxiety and depression and complicated grief, with the most determining variable being the risk of grief. Finally, the greater the age of the deceased and the longer the time spent in the PCU is linked to fewer symptoms of grief. However, important links have been found between the sufferers who have experienced stressful critical events prior to losing their loved one, with symptoms of depression, anxiety and complicated grief.Conclusions: The high numbers of cases of symptoms of complicated grief and levels of anxiety and clinical depression two months after a death suggests that early interventions should be carried out in those individuals with greater vulnerability.

Growth of calcium phosphate coating on Ti-7.5Mo alloy after anodic oxidation

Titanium and its alloys are widely used as biomaterials due to their mechanical, chemical and biological properties. To enhance the biocompatibility of titanium alloys, various surface treatments have been proposed. In particular, the formation of titanium oxide nanotubes layers has been extensively examined. Among the various materials for implants, calcium phosphates and hydroxyapatite are widely used clinically. In this work, titanium nanotubes were fabricated on the surface of Ti-7.5Mo alloy by anodization. The samples were anodized for 20 V in an electrolyte containing glycerol in combination with ammonium fluoride (NH4F, 0.25%), and the anodization time was 24 h. After being anodized, specimens were heat treated at 450 °C and 600°C for 1 h to crystallize the amorphous TiO2 nanotubes and then treated with NaOH solution to make them bioactive, to induce growth of calcium phosphate in a simulated body fluid. Surface morphology and coating chemistry were obtained respectively using, field-emission scanning electron microscopy (FEG-SEM), AFM and X-ray diffraction (XRD). It was shown that the presence of titanium nanotubes induces the growth of a sodium titanate nanolayer. During the subsequent invitro immersion in a simulated body fluid, the sodium titanate nanolayer induced the nucleation and growth of nano-dimensioned calcium phosphate. It was possible to observe the formation of TiO2 nanotubes on the surface of Ti-7.5Mo. Calcium phosphate coating was greater in the samples with larger nanotube diameter. These findings represent a simple surface treatment for Ti-7.5Mo alloy that has high potential for biomedical applications. © (2013) Trans Tech Publications, Switzerland.
