Importance: Data characterizing the severity and changing prevalence of bone mineral density (BMD) deficits and associated nonfracture consequences among childhood cancer survivors decades after treatment are lacking.
Objective: To evaluate risk for moderate and severe BMD deficits in survivors and to identify long-term consequences of BMD deficits.
Design, Setting, And Participants: This cohort study used cross-sectional and longitudinal data from the St Jude Lifetime (SJLIFE) cohort, a retrospectively constructed cohort with prospective follow-up.

Background: Right ventricular (RV) failure is a well-recognized pivotal prognostic factor of adverse outcomes in pulmonary artery hypertension (PAH), while RV dilation provides significant implications for adaptive or maladaptive changes. PAH is a predominant cause of mortality among patients with connective tissue disease (CTD). This study aims to elucidate the prognostic significance of RV morphology, as assessed by echocardiography (ECHO), in with CTD associated with PAH (CTD-PAH).

Background: Recent advancements in connectome analyses allow for more fine-grained measurements of brain network integrity. One measure of integrity is resilience, or the capacity of the network to retain functionality when confronted with endogenous or exogenous perturbations that result in damage or error. We assessed the impact of individual differences in the resilience of resting BOLD connectivity on the relationship between cognitive and brain changes in a lifespan cohort of cognitively healthy adults over a 5-year period.

The spatial-temporal relationship between the Aβ pathway and tau pathophysiology in AD, plays a crucial role in comprehending the pathogenesis and progression of AD. Understanding the interrelationship between Aβ and tau, is crucial to elucidate the failure of previous therapeutic strategies and understanding AD progression and will inform the next generation of clinical trials.

Background: Sleep and circadian disruption have been associated with cognitive impairment in older adults. However, little is known about the longitudinal change in 24-hour sleep-wake activity in oldest old adults and how profiles of sleep-wake changes may be associated with risk of mild cognitive impairment (MCI) and dementia.
Method: We studied 769 women (mean age = 82.
