Assessing 20-year follow-up data from a cohort for an international study of annual low-dose CT screening for lung cancer, researchers noted an 81 percent survival rate after an initial primary lung cancer diagnosis for over 1,200 patients with a median 43 pack-year smoking history.

Ultrasound and MRI findings from a new study suggest that greater carotid atherosclerosis and elevated white matter hyperintensities among women with the APOEe4 genotype, a strong risk factor for Alzheimer’s disease, are associated with increased PTSD symptoms in midlife women.

In their review of functional MRI data from over 5,200 study participants, researchers noted that higher amygdala reactivity and lower prefrontal cortical reactivity were associated with adversity exposure, findings that may contribute to exaggerated threat detection and reduced emotional control.

In a newly updated guidance, the American Cancer Society recommends the expansion of annual lung cancer screening with low-dose computed tomography (LDCT) for current or previous smokers 50 to 80 years of age who have a 20-pack-year or greater history of smoking.
