Obstetric-Related Emergency Medical Treatment and Labor Act Violations and No Health Exception Bans
The results of this difference-in-differences analysis suggest that strict abortion bans, particularly Senate bill 8 in Texas, were followed by a measurable escalation in EMTALA violations involving obstetric emergencies. Uncertainty regarding state policies and deferral to state law may reshape frontline emergency care and compromise federally protected access in obstetric emergencies
Do Purpose in Life and Social Support Mediate the Association between Religiousness/Spirituality and Mortality? Evidence from the Midus National Sample
We examined prospective associations between religiousness/spirituality (R/S; i.e., service attendance, R/S identity, R/S coping, spirituality) and all-cause mortality in the Midlife in the United States (MIDUS) sample, including whether having a purpose in life and positive social support are indirect pathways through which R/S predicts mortality. We examined service attendance and a composite of R/S identity, R/S coping, and spirituality from t…

Hispanic residential ethnic density and depression in post–acute coronary syndrome patients: Re-thinking the role of social support
BACKGROUND: The ethnic density hypothesis suggests that ethnic density confers greater social support and consequently protects against depressive symptoms in ethnic minority individuals. However, the potential benefits of ethnic density have not been examined in individuals who are facing a specific and salient life stressor. AIMS: We examined the degree to which the effects of Hispanic ethnic density on depressive symptoms are explained by soci…
Vitamin D Supplementation for Depressive Symptoms: A Systematic Review and Meta-Analysis of Randomized Controlled Trials
OBJECTIVE: The aim of this study was to review the effects of vitamin D supplementation on depressive symptoms in randomized controlled trials. Although low vitamin D levels have been observationally associated with depressive symptoms, the effect of vitamin D supplementation as an antidepressant remains uncertain. METHODS: MEDLINE, CINAHL, AMED, PsycINFO, Scopus, The Cochrane Library, and references of included reports (through May 2013) were se…
Trait anxiety and trait anger measured by ecological momentary assessment and their correspondence with traditional trait questionnaires
Directionality of the Relationship Between Depressive Symptom Dimensions and C-Reactive Protein in Patients With Acute Coronary Syndromes
OBJECTIVE: Previous theoretical models predict that elevated inflammation may predict later depressive symptoms, but bidirectional associations are possible. We examined whether depressive symptoms or inflammation predicts change in the other for a 3-month period in a sample of adults with acute coronary syndromes (ACS). METHODS: During hospitalization for their index ACS event (baseline) and then again 1 and 3 months later, 163 post-ACS patients…
