Clinical risk prediction models and informative cluster size: assessing the performance of a suicide risk prediction algorithm.
Investigators used data from seven health systems to predict suicide attempt within 90 days. They recommended dividing clustered data on the person level, rather than visit level, to ensure strong performance in prospective use and accurate estimation of future performance at the time of model development.

Depression as a risk factor for incident ischemic stroke among HIV-positive veterans in the veterans aging cohort study.
Background HIV infection and depression are each associated with increased ischemic stroke risk. Whether depression is a risk factor for stroke within the HIV population is unknown. In this study the investigators examined depression as a risk factor for incident ischemic stroke among HIV-positive veterans in the veterans aging cohort study. The investigators concluded that depression is associated with an increased risk of stroke among HIV-positive people after adjusting for sociodemographic characteristics, traditional cerebrovascular risk factors, and HIV-specific factors.

Racial/ethnic disparities in the performance of prediction models for death by suicide after mental health visits.
This study looked at racial/ethnic disparities in the performance of prediction models for death by suicide after mental health visit. The main outcome measured was the suicide rate within 90 days after a mental health visit. The study used a 50% sample of visits from a random set of outpatients at 7 large integrated health care systems by patients 13 years and older (6,984,184 visits). Suicide rates were highest for visits by patients with no race/ethnicity recorded, followed by Asian, White, American Indian/Alaskan Native, Hispanic, and Black. Sensitivity of both models used were high for White, Hispanic, and Asian patients and poor for Black and American Indian/Alaskan Native patients and patients with no race/ethnicity recorded.

The association between preterm birth and postpartum mental healthcare utilization among California birthing people.
This study’s objective was to determine whether preterm birth is associated with postpartum inpatient and emergency mental healthcare utilization. The study sample was taken from a database of live-born neonates delivered in California, 2011-2017, and included all births to singleton infants between the gestational ages of 20 and 44 weeks. The findings indicate found that preterm birth is an independent risk factor for postpartum mental healthcare utilization. These findings suggest that screening for and providing mental health resources to birthing people after delivery are crucial, particularly among people giving birth to preterm infants, regardless of mental health history.

Psychotic symptoms during bipolar depressive episodes and suicidal ideation.
Researchers examined the relationship between psychotic symptoms during a depressive episode and suicidal ideation in bipolar patients. Psychotic symptoms in adult, depressed outpatients with bipolar disorder (BD) in a comparative effectiveness study of quetiapine versus lithium were assessed via Bipolar Inventory of Signs and Symptoms Scale (BISS); depressive episodes were assessed via Mini-International Neuropsychiatric Interview (MINI). The researchers found that, while a small proportion of bipolar disorder outpatients had current symptoms of psychosis during their depressive episode, those who did were more likely to endorse active suicidal thoughts, including suicide methods and plans.
