Disentangling Sources of Momentum Fluctuations in Xe+Xe and Pb+Pb Collisions with the ATLAS Detector.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

The gap between surgeon goal and achieved sagittal alignment in adult cervical spine deformity surgery.

Objective: Malalignment following cervical spine deformity (CSD) surgery can negatively impact outcomes and increase complications. Despite the growing ability to plan alignment, it remains unclear whether preoperative goals are achieved with surgery. The objective of this study was to assess how good surgeons are at achieving their preoperative goal alignment following CSD surgery.

Basic Science and Pathogenesis.

Background: The ε4 allele of the apolipoprotein E (APOE) gene is the strongest genetic determinant for Alzheimer's disease and cognitive function in nearly all human populations, yet inconsistent effects have been reported in South Asians. The population of India has admixed genetic ancestry with most people falling on a North/South cline and having varying proportions of Ancestral North Indian (ANI) and Ancestral South Indian (ASI) ancestries, and those in east of India fall off the cline due to ancestry from additional ancestral populations. This study examined the ε4 association with cognitive function across 18 states/union territories of India and investigated whether ancestral background modulates ε4 association with cognitive function in 2,590 participants from the Longitudinal Aging Study in India - Diagnostic Assessment of Dementia (LASI-DAD).

Basic Science and Pathogenesis.

Background: The prevalence of dementia in India is approximately 7.4% among those aged 60 years and older, yet little is known about genetic risk factors for dementia in this population. Examining genetic variants at higher frequency in India than other ancestries (i.

Clinical Manifestations.

Background: How clinicians discuss, document, and diagnose health concerns within a visit shapes patient perceptions of their health conditions. Undiagnosed hearing loss among older adults with dementia or cognitive concerns may exacerbate neuropsychiatric symptoms and care challenges. This study investigates clinician documentation of hearing concerns and whether documentation, diagnosis, and referral vary for older adults with dementia/cognitive concerns.
