Popcorn is a whole-grain food/snack that is included among foods recommended in the 2005 Dietary Guidelines for Americans and MyPyramid to increase whole-grain consumption. The purpose of the present study was to use 1999-2002 National Health and Nutrition Examination Survey 24-hour dietary recall data to determine the average popcorn intake among Americans, and whether popcorn consumers exhibited different dietary intake patterns or physiological biomarkers of cardiovascular disease compared with popcorn non-consumers. Mean intake among consumers of popcorn was 38.8 g/day. Compared with non-consumers, popcorn consumers had approximately 250% higher (P<0.01) intake of whole grains (2.5 vs 0.70 servings/day) and approximately 22% higher (P<0.01) intake of fiber (18.1 vs 14.9 g/day). Small but significant differences (P<0.01) were also observed for intake of carbohydrate, magnesium (higher intake in popcorn consumers), protein, niacin, and folate (lower intake in popcorn consumers). In addition, popcorn consumers had a greater (P<0.01) intake of total grains and consumed fewer meat servings. Popcorn consumption was associated with increased intake of whole grains, dietary fiber, and certain other nutrients.

Spaceflight-induced multi-organ dysfunction affects the health of astronauts and the safety of in-orbit flight. However, the effect of microgravity on the kidney and the underlying mechanisms are unknown. In the current study, we used a hindlimb unweighting (HU) animal model to simulate microgravity and employed histological analysis, ischemia-reperfusion experiments, renal ultrasonography, bioinformatics analysis, isometric force measurement, and other molecular experimental settings to evaluate the effects of microgravity on the kidneys and the underlying mechanisms involved in this transition.

Objective: We investigated associations between per- and polyfluoroalkyl substances (PFAS) and changes in diabetes indicators from pregnancy to 12 years after delivery among women with a history of gestational diabetes mellitus (GDM).
Research Design And Methods: Eighty Hispanic women with GDM history were followed from the third trimester of pregnancy to 12 years after delivery. Oral and intravenous glucose tolerance tests were conducted during follow-up.
Phenotypic Classification of Multisystem Inflammatory Syndrome in Children Using Latent Class Analysis.
JAMA Netw Open
January 2025
Coronavirus and Other Respiratory Viruses Division, National Center for Immunization and Respiratory Diseases, Centers for Disease Control and Prevention, Atlanta, Georgia.
Importance: Multisystem inflammatory syndrome in children (MIS-C) is an uncommon but severe hyperinflammatory illness that occurs 2 to 6 weeks after SARS-CoV-2 infection. Presentation overlaps with other conditions, and risk factors for severity differ by patient. Characterizing patterns of MIS-C presentation can guide efforts to reduce misclassification, categorize phenotypes, and identify patients at risk for severe outcomes.

Importance: The net clinical effect of early vs later direct oral anticoagulant (DOAC) initiation after atrial fibrillation-associated ischemic stroke is unclear.
Objective: To investigate whether early DOAC treatment is associated with a net clinical benefit (NCB).
Design, Setting, And Participants: This was a post hoc analysis of the Early Versus Late Initiation of Direct Oral Anticoagulants in Post-Ischaemic Stroke Patients With Atrial Fibrillation (ELAN) open-label randomized clinical trial conducted across 103 sites in 15 countries in Europe, the Middle East, and Asia between November 6, 2017, and September 12, 2022, with a 90-day follow-up.

Department of Neurology, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Republic of Korea.
Importance: Nelonemdaz selectively antagonizes the 2B subunit of the N-methyl-d-aspartate glutamate receptor and scavenges free radical species.
Objective: To evaluate whether nelonemdaz enhances the clinical outcomes of patients with acute ischemic stroke undergoing emergent reperfusion therapy.
Design, Setting, And Participants: This multicenter double-blind placebo-controlled randomized phase 3 trial (December 25, 2021, to June 30, 2023, in South Korea) recruited patients with acute ischemic stroke who met the following criteria: National Institutes of Health Stroke Scale score greater than or equal to 8, Alberta Stroke Program Early Computed Tomography score greater than or equal to 4, and endovascular thrombectomy within 12 hours after stroke onset.
