Little is known about the use of antipsychotics in pregnancy and the corresponding plasma levels in the newborn child. We report on a woman with schizophrenia treated with olanzapine during pregnancy. Plasma levels of olanzapine were assessed both from the mother and from umbilical cord. The plasma level of the newborn (11 ng/mL) was about one third(More)
We here report on a psychotic mother and her breast-fed infant who was treated with olanzapine. Consecutively olanzapine concentrations in the milk and plasma of the mother and in the infant were measured with tandem mass spectroscopy over a period of five month. The results show a relatively high plasma level in the infant aged four month, probably(More)
OBJECTIVE The following crossover pilot study attempts to prove the effects of endurance training through mountain hiking in high-risk suicide patients. METHOD Participants (n = 20) having attempted suicide at least once and clinically diagnosed with hopelessness were randomly distributed among two groups. Group 1 (n = 10) began with a 9-week hiking phase(More)
Many studies have found elevated levels of suicide ideation and attempts among sexual minority (homosexual and bisexual) individuals as compared to heterosexual individuals. The suicide risk difference has mainly been explained by minority stress models (MSTM), but the application of established suicidological models and testing their interrelations with(More)
Many studies have reported higher rates of suicide attempts among sexual minority individuals compared with their heterosexual counterparts. For suicides, however, it has been argued that there is no sexual orientation risk difference, based on the results of psychological autopsy studies. The purpose of this article was to clarify the reasons for the(More)
The validity of self-reported suicide attempt information is undermined by false positives (e.g., incidences without intent to die), or by unreported suicide attempts, referred to as false negatives. In a sample of 1,385 Austrian adults, we explored the occurrence of false positives and false negatives with detailed, probing questions. Removing false(More)
Religion is known to be a protective factor against suicide. However, religiously affiliated sexual minority individuals often report a conflict between religion and sexual identity. Therefore, the protective role of religion against suicide in sexual minority people is unclear. We investigated the effect of religion on suicide risk in a sample of 358(More)
Despite decades of research, the prediction of suicidal behavior remains limited. As a result, searching for more specific risk factors and testing their predictive power are central in suicidology. This strategy may be of limited value because it assumes linearity to the suicidal process that is most likely nonlinear by nature and which can be more(More)
Previous studies indicate that homosexual or bisexual individuals are at a higher risk of attempting suicide compared to heterosexuals. To overcome biases in these studies, more rigorous definitions of "suicide attempts" and the assessment of multiple dimensions of sexual orientation are needed. In addition, studies from the German speaking region are(More)
BACKGROUND Regular physical activity promotes physical and mental health. Psychiatric patients are prone to a sedentary lifestyle, and accumulating evidence has identified physical activity as a supplemental treatment option. METHODS This prospective, randomized, crossover study evaluated the effects of hiking in high-risk suicidal patients (n = 20) who(More)
