Background: Sudden cardiac death (SCD) in early adults aged 25 to 44 years represents an important and unexpected cause of death. We assessed trends in SCD-related mortality in the United States from 1999 to 2020 among early adults to determine differences by sex, ethnoracial groups, urbanization, and census region.
Methods And Results: Mortality data were retrieved from the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research (CDC WONDER) data set from 1999 to 2020.
Article Synopsis
- The study investigates sex differences in treatment approaches for pulmonary embolism (PE) among older adults, revealing that existing evidence on disparities is limited and often inconclusive due to small sample sizes and inadequate methods.
- Analysis of data from a European PE registry and US Medicare beneficiaries shows no significant overall sex differences in the use of anticoagulation or advanced therapies, although fewer women received fibrinolytic therapy compared to men with intermediate-risk PE.
- The authors suggest that future research should explore whether the observed sex disparities in treatment correlate with different clinical outcomes, especially regarding fibrinolytic therapy and advanced treatment utilization in older adults in the US.
Tau protein blood levels dependent on its distribution to peripheral organs and possible elimination from the body. Thus, the peripheral distribution of CSF-derived tau protein was explored, especially since there is a transition to blood-based biomarkers and the emerging idea that tau pathology may spread beyond brain. Near infrared fluorescence (NIRF) was mainly used to analyze tau (tau-NIRF) distribution after its intracisternal or intravenous injection.

Because many DCIS cases never progress to invasive ductal carcinomas (IDC), overtreatment remains a significant problem. Up to 20% patients experience disease recurrence, indicating that standard treatments do not effectively treat DCIS for a subset of patients.

In addition, for antibodies that target the spike protein (SP), it's unclear if these reduce SARS-CoV-2/SP multiorgan tropism equally. We used fluorescently labeled SP-NIRF to study viral behavior, using an in vivo dynamic imaging system and ex in vivo tissue analysis, in young mice.
