Highlights •Circulating monocytes migrate to the bone marrow upon fasting•Monocytes augment CXCR4 via a fasting-induced hormonal stress response•Re-feeding after prolonged fasting results in a surge of monocytes into circulation•Prolonged fasting and re-feeding alter the immune response to bacterial infection SummaryDiet profoundly influences physiology. Whereas over-nutrition elevates risk for disease via its influence on immunity and… Continue reading Monocytes re-enter the bone marrow during fasting and alter the host response to infection

Examining understandability, information quality, and presence of misinformation in popular YouTube videos on sleep compared to expert-led videos
The Internet is a common source of sleep information, but may be subject to commercial bias and misinformation. We compared the understandability, information quality, and presence of misinformation of popular YouTube videos on sleep to videos with credible experts. We identified the most popular YouTube videos on sleep/insomnia and 5 videos from experts. Videos were… Continue reading Examining understandability, information quality, and presence of misinformation in popular YouTube videos on sleep compared to expert-led videos
Oral mucosal breaks trigger anti-citrullinated bacterial and human protein antibody responses in rheumatoid arthritis
Periodontal disease is more common in individuals with rheumatoid arthritis (RA) who have detectable anti-citrullinated protein antibodies (ACPAs), implicating oral mucosal inflammation in RA pathogenesis. Here, we performed paired analysis of human and bacterial transcriptomics in longitudinal blood samples from RA patients. We found that patients with RA and periodontal disease experienced repeated oral bacteremias… Continue reading Oral mucosal breaks trigger anti-citrullinated bacterial and human protein antibody responses in rheumatoid arthritis

Food Insufficiency, Supplemental Nutrition Assistance Program (SNAP) Status, and 9-Year Trajectory of Cognitive Function in Older Adults: The Longitudinal National Health and Aging Trends Study, 2012–2020
BackgroundDespite findings from cross-sectional studies, how food insecurity experience/Supplemental Nutrition Assistance Program (SNAP) status relates to cognitive decline over time has not been fully understood.ObjectivesWe aimed to investigate the longitudinal associations between food insecurity/SNAP status and cognitive function in older adults (≥65 y).MethodsLongitudinal data from the National Health and Aging Trends Study 2012–2020 were analyzed… Continue reading Food Insufficiency, Supplemental Nutrition Assistance Program (SNAP) Status, and 9-Year Trajectory of Cognitive Function in Older Adults: The Longitudinal National Health and Aging Trends Study, 2012–2020
Patients with isolated REM-sleep behavior disorder have elevated levels of alpha-synuclein aggregates in stool
Misfolded and aggregated α-synuclein is a neuropathological hallmark of Parkinson’s disease (PD). Thus, α-synuclein aggregates are regarded as a biomarker for the development of diagnostic assays. Quantification of α-synuclein aggregates in body fluids is challenging, and requires highly sensitive and specific assays. Recent studies suggest that α-synuclein aggregates may be shed into stool. We used… Continue reading Patients with isolated REM-sleep behavior disorder have elevated levels of alpha-synuclein aggregates in stool
Air pollution and decreased bone mineral density among Women’s Health Initiative participants
BackgroundOsteoporosis heavily affects postmenopausal women and is influenced by environmental exposures. Determining the impact of criteria air pollutants and their mixtures on bone mineral density (BMD) in postmenopausal women is an urgent priority.MethodsWe conducted a prospective observational study using data from the ethnically diverse Women's Health Initiative Study (WHI) (enrollment, September 1994–December 1998; data analysis,… Continue reading Air pollution and decreased bone mineral density among Women’s Health Initiative participants
Associations between types and sources of dietary carbohydrates and cardiovascular disease risk: a prospective cohort study of UK Biobank participants
Recent studies have reported that the associations between dietary carbohydrates and cardiovascular disease (CVD) may depend on the quality, rather than the quantity, of carbohydrates consumed. This study aimed to assess the associations between types and sources of dietary carbohydrates and CVD incidence. A secondary aim was to examine the associations of carbohydrate intakes with… Continue reading Associations between types and sources of dietary carbohydrates and cardiovascular disease risk: a prospective cohort study of UK Biobank participants
Fulminant myocarditis with complete atrioventricular block after mRNA COVID-19 vaccination: A case report
A 71-year-old man was transferred urgently to our hospital after collapsing near his home post the first shot of the BNT162b2 coronavirus disease 2019 vaccine (Pfizer-BioNTech, Comirnaty®). Immediately after arrival at our hospital, cardiac arrest due to complete atrioventricular block with no ventricular escaped beats was observed on electrocardiogram. Echocardiography showed preserved left ventricular ejection… Continue reading Fulminant myocarditis with complete atrioventricular block after mRNA COVID-19 vaccination: A case report
