Plasma and neuroimaging biomarkers of small vessel disease and Alzheimer's disease in a diverse cohort: MESA

open access: yesAlzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION Little is known about how Alzheimer's disease (AD) plasma biomarkers relate to cerebral small vessel disease (cSVD) neuroimaging biomarkers. METHODS The study involved 251 Wake Forest Multi‐Ethnic Study of Atherosclerosis (MESA) Exam 6 participants with plasma AD biomarkers, magnetic resonance imaging, amyloid positron emission ...

Cerebrovascular regulation dynamics and Alzheimer's neuroimaging phenotypes

open access: yesAlzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION Cerebrovascular dysfunction may contribute to Alzheimer's disease (AD) pathogenesis. We examined how novel cerebral hemodynamic markers relate to neuroimaging phenotypes associated with AD dementia in cognitively impaired and unimpaired older adults.

Temporal dynamics of white matter hyperintensities related to Alzheimer's disease in adults with Down syndrome

open access: yesAlzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION White matter hyperintensities (WMH) are common in Down syndrome (DS), yet their longitudinal evolution and associations with Alzheimer's disease (AD) remain unclear. METHODS Longitudinal MRI study, including 80 DS adults and 53 euploid controls. WMH were segmented on serial FLAIR using a longitudinal pipeline.

Carbonate sedimentology: An evolved discipline

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
Abstract Although admired and examined since antiquity, carbonate sediment and rock research really began with Charles Darwin who, during a discovery phase, studied, documented and interpreted their nature in the mid‐19th century. The modern discipline, however, really began after World War II and evolved in two distinct phases.

Virtual reality exoskeleton for post‐partum uterine tamponade balloon training: Impact on learning and operator satisfaction

open access: yesInternational Journal of Gynecology &Obstetrics, Volume 172, Issue 2, Page 903-910, February 2026.
Abstract Background Virtual reality's (VR) use in medical education is increasing; however, traditional VR controllers lack real‐world dexterity. A post‐partum hemorrhage (PPH) is an obstetric emergency with significant maternal morbidity. The use of an intrauterine balloon reduces the need for further surgical interventions, but resident doctors might

Reference Methods for Measuring Skeletal Muscle Mass: A Critical Perspective

open access: yesJournal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 1, February 2026.
ABSTRACT Skeletal muscle (SM) is an integral organ component in the pathophysiology of many acute and chronic diseases. But is there a ‘gold’ standard or accepted reference method for quantifying the amount and composition of human SM mass? Exploring that question led us to recognize the existence of a SM measurement paradigm that divides methods into ...
