Objective: This prospective study aimed to describe the nature and time course of HPA axis dysregulation and psychopathology among terror-bereaved spouses.
Method: Twenty-three spouses bereaved from September 11, 2001 terror attacks and 22 nonbereaved spouses were compared using a psychiatric diagnostic interview (SCID), 3 days of salivary cortisol collection, and a dexamethasone suppression test. Most subjects had repeated assessments at 6 month intervals during the 2 year study.
Results: After September 11, 2001, bereaved compared to nonbereaved had significantly higher rates ofposttraumatic stress disorder (PTSD; 68.1% versus 0%) and major depressive disorder (MDD; 45.5% versus 9.5%). Bereaved had significantly higher morning basal cortisol and less afternoon postdexamethasone cortisol suppression than nonbereaved. Among bereaved, those with PTSD without comorbid MDD had significantly greater afternoon postdexamethasone cortisol suppression than those without psychiatric disorders.
Conclusions: Terror-related spouse death is a severe stressor associated with persistent HPA axis activation, PTSD, and MDD. However, bereaved spouses who developed PTSD and were not depressed had enhanced postdexamethasone cortisol suppression, evidence of heightened glucocorticoid receptor sensitivity.

Studying climate change's impact on vegetation canopy growth and senescence is significant for understanding and predicting vegetation dynamics. However, there is a lack of adequate research on canopy changes across the lifecycles of different vegetation types. Using GLASS LAI (leaf area index) data (2001-2020), we investigated canopy development (April-June), maturity (July-August), and senescence (September-October) rates in Northeast China, focusing on their responses to preseason climatic factors.

The rapid aging of the population has led to an increase in the number of cutaneous squamous cell carcinoma (cSCC) cases among the older population. However, the characteristics of these cases remain unclear. In this study, we aimed to identify the problem by analyzing the clinical characteristics of patients with cSCC aged 90 years and over.

Background: Perimembranous ventricular septal defect (PMVSD) is a prevalent congenital heart disease, presenting challenges in predicting spontaneous closure, which is crucial for therapeutic decisions. Existing models mainly rely on structured echocardiographic parameters or restricted data. This study introduces an artificial intelligence (AI)-based model, which uses natural language processing (NLP) and machine learning with the aim of improving spontaneous closure predictability in PMVSD.

Importance: It remains unclear how socioeconomic status (SES) is related to the association between diet and health, as well as the role of behavioral factors, in explaining socioeconomic disparities in health outcomes.
Objective: To investigate the associations of neighborhood and individual SES factors, as well as behavioral factors, particularly dietary pattern, with health outcomes.
Design, Setting, And Participants: This prospective cohort study included US health professionals without chronic diseases at baseline who were enrolled in the Health Professionals Follow-Up Study (calendar years 1988-2018), the Nurses' Health Study (calendar years 1992-2018), and the Nurses' Health Study II (calendar years 2001-2019).
