Introduction: We investigated the association of the area deprivation index (ADI) with cognitive decline, mild cognitive impairment (MCI), and dementia in older adults (≥50 years old). ADI is a neighborhood socioeconomic disadvantage measure assessed at the census block group level.

Methods: The study included 4699 participants, initially without dementia, with available ADI values for 2015 and at least one study visit in 2008 through 2018.

Background: Refractory epilepsy confers a considerable lifetime risk of sudden unexplained death in epilepsy (SUDEP). Mechanisms may overlap with sudden cardiac death (SCD), particularly regarding QTc prolongation. Guidelines in the United States do not mandate the use of electrocardiography (ECG) in diagnostic evaluation of seizures or epilepsy.

Background: Multimorbidity (defined as ≥2 chronic conditions) has been associated with increased risk of mild cognitive impairment and cross-sectionally with imaging biomarkers of neurodegeneration in cognitively unimpaired persons aged ≥70 years. Its association with preclinical Alzheimer's disease stages has not been studied in detail yet. The objective of the study was to assess the cross-sectional association of multimorbidity with preclinical Alzheimer's disease stages and suspected non-amyloid pathophysiology in cognitively unimpaired participants of the Mayo Clinic Study of Aging (≥50 years of age).

Background: There is accumulating evidence suggesting that diet may play a role in preventing or delaying cognitive decline and dementia, but the underlying biological mechanisms are not well understood.

Objectives: To examine the cross-sectional associations of the Mediterranean diet (MeDi) and its components with 11C-PiB-PET scan measures of amyloid-β (Aβ) deposition.

Methods: The study consisted of 278 Mayo Clinic Study of Aging participants 70+ years old, who were cognitively unimpaired (CU) at the time of completion of the Food Frequency Questionnaire (FFQ) and when they underwent PET imaging.

Importance: Brain amyloid deposition is a marker of Alzheimer disease (AD) pathology. The population-based prevalence and outcomes of amyloid positivity in a population without dementia are important for understanding the trajectory of amyloid positivity to clinically significant outcomes and for designing AD prevention trials.

Objective: To determine prevalence and outcomes of amyloid positivity in a population without dementia.

One of the most controversial health decisions facing women is deciding upon the use of hormonal treatments for symptoms of menopause. This brief review focuses on the historical context of use of menopausal hormone treatments (MHT), summarizes results of major observational, primary and secondary prevention studies of MHT and cardiovascular (CV) outcomes, provides evidence for how sex steroids modulate CV function and identifies challenges for future research. As medicine enters an era of personalization of treatment options, additional research into sex differences in the aetiology of CV diseases will lead to better risk identification for CV disease in women and identify whether a woman might receive CV benefit from specific formulations and doses of MHT.

Objective: To assess the cross-sectional association between multimorbidity and imaging biomarkers of brain pathology in the population-based Mayo Clinic Study of Aging (MCSA).

Methods: The study consisted of 1,449 MCSA participants who were cognitively normal at the time of MRI. A subset of the participants also had (11)C-Pittsburgh compound B (n = 689) and (18)fluorodeoxyglucose (n = 688) PET scans available.

Rationale: The management of severe and refractory hypoxemia in critically ill adult patients is practice based. Variability across individual practitioners and institutions is not well documented.

Objectives: To conduct a nationwide survey of critical care physicians in the United States regarding accepted definitions and management strategies for severe and refractory hypoxemia.

Importance: Unintentional weight loss has been associated with risk of dementia. Because mild cognitive impairment (MCI) is a prodromal stage for dementia, we sought to evaluate whether changes in weight and body mass index (BMI) may predict incident MCI.

Objective: To investigate the association of change in weight and BMI with risk of MCI.

Importance: To increase the opportunity to delay or prevent mild cognitive impairment (MCI) or Alzheimer disease (AD) dementia, markers of early detection are essential. Olfactory impairment may be an important clinical marker and predictor of these conditions and may help identify persons at increased risk.

Objective: To examine associations of impaired olfaction with incident MCI subtypes and progression from MCI subtypes to AD dementia.

Background: The incidence and outcomes of disseminated intravascular coagulation (DIC) are incompletely defined. Therefore, we aimed to evaluate the trends in incidence and outcomes of critically ill patients with DIC.

Methods: We conducted a population-based, retrospective cohort study evaluating consecutively admitted adult (≥ 18 years old) critically ill patients with DIC at the Mayo Clinic, Minnesota, from 2004 to 2010.
