- OBJECTIVE:: To determine whether death ideation in late life is associated with markers of elevated risk for suicide, or reflects normal psychological processes in later life. DESIGN/SETTING:: Population-based cross-sectional study in Gothenburg, Sweden. PARTICIPANTS:: The sample consists of 345 men and women of age 85 years (born 1901-1902) and living in Gothenburg, Sweden. MAIN OUTCOME MEASURES:: The Paykel Scale measured the most severe level of suicidality over an individual's lifetime. Other key measures were severity of depression and anxiety and frequency of death/suicidal ideation over the previous month. RESULTS:: Latent class analysis revealed distinct groups of older adults who reported recent death ideation. Recent death ideation did not occur apart from other risk factors for suicide; instead individuals reporting recent death ideation also reported either 1) recent high levels of depression and anxiety, or 2) more distant histories of serious suicidal ideation (indicative of worst point severity of suicidal ideation)-both of which elevate risk for eventual suicide. CONCLUSIONS:: Our results indicate a heterogeneous presentation of older adults who report death ideation, with some presenting with acute distress and suicidal thoughts, and others presenting with low distress but histories of serious suicidal ideation. The presence of death ideation is associated with markers of increased risk for suicide, including "worst point" active suicidal ideation.

- Objective: Women experiencing hypertensive pregnancies have an increased risk for cardiovascular disease. Whether stress increase the risk is unknown. The objective was to test if cardiovascular response to stress and/or perceived stress differed in relation to blood pressure status during pregnancy 40 years earlier. Methods: Cardiovascular response was examined with mental stress test, and perceived stress was evaluated with a questionnaire in 105 women. Results: Resting heart rate was higher, and pulse reactivity was lower in women with previous hypertensive pregnancies. Neither blood pressure nor perceived stress differed. Conclusion: Response to physical or psychological stress is not affected many years after pregnancy.

Predicting intensive care need in women with preeclampsia using machine learning–a pilot study

- Background: Predicting severe preeclampsia with need for intensive care is challenging. To better predict high-risk pregnancies to prevent adverse outcomes such as eclampsia is still an unmet need worldwide. In this study we aimed to develop a prediction model for severe outcomes using routine biomarkers and clinical characteristics. Methods: We used machine learning models based on data from an intensive care cohort with severe preeclampsia (n=41) and a cohort of preeclampsia controls (n=40) with the objective to find patterns for severe disease not detectable with traditional logistic regression models. Results: The best model was generated by including the laboratory parameters aspartate aminotransferase (ASAT), uric acid and body mass index (BMI) with a cross-validation accuracy of 0.88 and an area under the curve (AUC) of 0.91. Our model was internally validated on a test-set where the accuracy was lower, 0.82, with an AUC of 0.85. Conclusion: The clinical routine blood parameters ASAT and uric acid as well as BMI, were the parameters most indicative of severe disease. Aspartate aminotransferase reflects liver involvement, uric acid might be involved in several steps of the pathophysiologic process of preeclampsia, and obesity is a well-known risk factor for development of both severe and non-severe preeclampsia likely involving inflammatory pathways.

- OBJECTIVE: The aim of the present study was to evaluate the autonomic balance in women with preeclampsia and in healthy women during and after pregnancy by means of a 24-h ECG Holter recording combined with power spectral analysis. METHODS: Fifteen preeclamptic and 15 healthy women underwent 24-h Holter monitoring in the 32nd-36th week of gestation and 3-6 months postpartum. The power spectrum of the maternal electrocardiogram was analyzed with an autoregressive algorithm. MAIN OUTCOME MEASURES: The power spectrum contains two major components: a low-frequency peak, primarily attributed to sympathetic tone, and a high-frequency peak, reflecting vagal tone. RESULTS: The power spectrum of maternal heart rate variability did not differ between preeclamptic and normal women during pregnancy. After delivery, the amplitude of all components became significantly higher than those during pregnancy, with one exception: the high-frequency component in the patients who had been preeclamptic. In a comparison of the two groups, the high-frequency component after delivery was significantly lower in women who had preeclampsia than in normal healthy women (p = 0.03). CONCLUSIONS: During pregnancy, the power spectrum is reduced and cannot be used to distinguish between patients with preeclampsia and normal healthy women. Three to 6 months after delivery, the high-frequency component is still reduced in the preeclamptic group of women. This indicates an impaired vagal modulation even in the nonpregnant state in this group of women, unlike those who had a normotensive pregnancy.
