Factores psicológicos asociados al riesgo suicida en estudiantes universitarios de Honduras / Factors Related to Suicide Risk in University Students from Honduras / Fatores psicológicos associados ao risco de suicídio em estudantes universitários em Honduras

El riesgo suicida es definido como la posibilidad de que una persona atente deliberadamente contra su vida y se considera una conducta autodestructiva de causas multifactoriales. El propósito de esta investigación fue determinar los factores psicológicos aso-ciados al riesgo suicida en estudiantes universitarios. Esto se realizó por medio de un enfoque cuantitativo no experimental. La muestra estuvo conformada por 1696 estudiantes de pregrado, 54.7 % correspondiente al sexo femenino y 43.6 % al masculino. Se aplicaron escalas para evaluar sentido de la vida, depresión, esperanza, soledad, apoyo interpersonal y riesgo suicida. Los resultados indicaron que el 50 % de la muestra reportó nunca haber tenido pensamientos suicidas. Sin embargo, el 26.8 % tuvo un pensamiento pasajero al respecto; el 9.9 % planeó quitarse la vida, pero no lo intentó; el 5.8 % realizó un intento suicida sin intención real de concretar el acto, el 5 % hizo planes para quitarse la vida con intención real de concretar el acto; y el 2.4 % efectuó intentos suicidas con deseos de morir. Se evidenció que existe una relación inversa significativa entre el riesgo suicida y la esperanza, presencia y búsqueda de sentido de la vida y apoyo interpersonal. No obstante, los individuos con mayor riesgo suicida poseen puntajes más altos en soledad y depresión. Estos resultados se discuten desde sus implicaciones en el ejercicio clínico

Suicide risk is defined as the possibility of a person deliberately taking his/her own life; this is considered a self-destructive behavior with multifactorial causes. This research aimed to determine the psychological fac-tors associated with suicide risk in university students. This was done through a quantitative, non-experimental approach. The sample consisted of 1.696 undergraduate students, 54.7 % female and 43.6 % male students. Ques-tionnaires were applied to evaluate meaning in life, depression, hope, loneliness, interpersonal support, and suicide risk. The results indicated that 50 % of the parti-cipants reported never having suicidal thoughts. However, 26.8 % had had a passing thought about committing suicide, 9.9 % had thought of a specific (but unexecuted) plan to commit suicide, 5.8 % reported a previous suicide attempt without the intention of actually committing suicide, 5 % had made plans to take their own life with a real intention to commit the act, and 2.4 % had made at least one suicide attempt with a desire to die. Results indicate that there is a significant inverse relation be-tween suicide risk and hope, the presence and search for a meaning in life, and interpersonal support. However, a higher suicide risk is positively correlated with loneliness and depression. These results are discussed according to their implications in clinical practice

A amostra foi composta por 1696 alunos de graduação, sendo 54.7 % do sexo feminino e 43.6 % do sexo mascu-lino.

Mixing of an anthracene-contaminated soil: a simple but efficient remediation technique?

Contamination of soils with polycyclic aromatic hydrocarbons (PAHs) is a serious problem in petroleum producing countries, such as México, and environment-friendly easy to apply techniques are required to accelerate the removal of the contaminants. Removal of anthracene was monitored in an arable and a pasture soil regularly mixed or amended with organic material, a non-ionic surfactant (Surfynol(®) 485) or earthworms (Eisenia fetida (Savigny, 1826)). In both soils the same results were obtained although the removal of anthracene was faster from the pasture than from the arable soil. The fastest removal of anthracene was obtained when the soil was mixed every 7 days and no contaminant was detected in both soils after 56 days. The second fastest removal of anthracene was obtained when earthworms were added to soil and no contaminant was detected in both soils after 112 days. Application of organic material that served as feed for the earthworms also accelerated the removal of the contaminant compared to the unamended soil, but application of the surfactant inhibited the dissipation of the contaminant. Only 37% of the spiked anthracene was removed from soil when surfactant was applied, while 62% was dissipated in the unamended soil after 112 days. It was found that simply mixing a soil removed anthracene faster than when earthworms were applied, while the application of the surfactant inhibited the removal of anthracene by the autochthonous soil microorganisms.
