Ischemic stroke induces rapid loss in bone mineral density that is up to 13 times greater than
during normal aging, leading to a markedly increased risk of fracture. Little is known about …

Rationale Stroke patients lose bone mass and experience fracture at an elevated rate. Although
functional intraosseous vasculature is necessary for skeletal maintenance, the effect of …

Although body mass index is positively associated with bone mineral density, suggesting
obesity is protective against fracture, elderly obese individuals experience greater fracture risk …

Mechanisms for rapid stroke-induced bone loss are unknown. Using a mouse stroke model,
we examined whether vascular changes in bone may contribute. Compared to sham, stroke …

Background The evidence base for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2)
is nascent. We sought to characterize SARS-CoV-2 transmission within US …

METHODS: We enrolled individuals with coronavirus disease 2019 and their household
contacts, assessed daily symptoms prospectively for 14 days, and obtained specimens for …

Background To better understand severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)
shedding and infectivity, we estimated SARS-CoV-2 RNA shedding duration, …

Importance As self-collected home antigen tests become widely available, a better understanding
of their performance during the course of SARS-CoV-2 infection is needed. Objective …

H7N9 avian influenza virus causes severe infections and might have the potential to trigger
a major pandemic. Molecular determinants of human humoral immune response to N9 …

Background Real-time reverse transcription polymerase chain reaction (rRT-PCR) and
antigen tests are important diagnostics for severe acute respiratory syndrome coronavirus 2 (…
