Study finds long COVID leaves a distinct immune signature in the blood

Researchers identified a small panel of inflammatory and neurology-related blood proteins that may help distinguish long COVID from recovery or no prior infection, while also showing that booster vaccination did not appear to worsen these protein responses in this cohort. The study also found that immune responses after reinfection differed from those seen after the first SARS-CoV-2 infection, suggesting altered long-term immune behavior in some previously infected individuals.

SARS-CoV-2 rarely reaches first-trimester placentas but still disrupts early pregnancy immunity

Researchers analyzing 761 first-trimester pregnancies found that SARS-CoV-2 was rarely detected in placental tissues, suggesting in utero transmission early in pregnancy is uncommon. However, maternal infection was linked to immune dysregulation at the maternal-fetal interface, altered trophoblast signaling, and inflammatory changes that could affect placental development.

Lab study shows cigarette smoke damaged lung cells more than e-cigarette vapor

Researchers found that cigarette smoke extract disrupted the lung cell barrier, increased IL-6 inflammation, and caused DNA damage in Calu-3 cells, while e-cigarette vapor extract showed no significant adverse effects on these measures under the study conditions. The authors caution that these were in vitro findings using liquid extracts and unflavored e-liquid, so they do not directly predict long-term human health outcomes.

Study reveals lung-brain link between smoking and neurodegeneration

The correlation between smoking and neurodegeneration is well-documented, with one study from 2011 finding heavy smoking in midlife was associated with a greater than 100% increase in risk of dementia, Alzheimer's and vascular dementia more than two decades later.

Flu vaccines protect children well across Europe, but H3N2 remains harder to stop

Influenza vaccination provided strong real-world protection for children in European primary care across two seasons, with overall vaccine effectiveness of 68% in 2022–2023 and 71% in 2023–2024. Protection was highest against influenza B and H1N1, while H3N2 showed lower and more variable effectiveness, supporting the need for higher uptake and continued monitoring.

Researchers track how youth drinking deaths changed worldwide over 31 years

A global analysis of GBD 2021 data found that youth drinking contributed to 417,198 deaths across 194 WHO member countries and territories between 1990 and 2021, with deaths declining from 13,346 to 10,563 over the period. Boys and young men bore a far higher burden, and most alcohol-attributable deaths were linked to transport injuries, interpersonal violence, and self-harm, with marked disparities across SDI levels and countries.
