BREAKING: Elizabeth Warren has introduced a bill that would allow you to file taxes for free directly with the IRS. The bill has support on both sides of the aisle, and would bring back and expand the free taxing filing program that the Trump administration killed off.



Fatigue in Post-COVID-Condition is accompanied by hypoperfusion of right-occipital areas 🔥A German eye-opener: COVID-19 itself leaves lasting brain blood-flow reduction, even after full recovery! ➡️“In PCC patients, fatigue was associated with reduced perfusion in right-sided occipital regions, suggesting a potential pathophysiological basis for this symptom.” ➡️“These findings may also provide an imaging biomarker to aid in the diagnosis of PCC”. ‼️But when we dig deeper: ➡️In this prospective cohort of Post-COVID Condition (PCC) patients, severe fatigue (especially physical) strongly correlated with reduced cerebral blood flow (CBF) in the right middle and inferior occipital gyrus. ➡️No global or cortical atrophy vs. recovered COVID-19 controls (FreeSurfer analysis). ➡️No significant group differences in regional CBF after FDR correction, but at an exploratory threshold (p<0.005) reduced CBF in right angular & middle occipital gyrus in PCC, was demonstrated. ➡️SARS-CoV-2 infection itself – even mild and fully recovered – causes persistent cerebral hypoperfusion (mainly frontotemporal) that can still be detected months later. ➡️Previous Long COVID imaging studies that used never-infected “healthy” controls were therefore confounded, much of the reported hypoperfusion may simply reflect residual effects of having had COVID-19, not PCC-specific pathology. ➡️By using recovered COVID-19 subjects as controls, this study better isolates fatigue-related right-sided occipital hypoperfusion as a feature more specific to ongoing Post-COVID Condition, mirroring patterns seen in ME/CFS. ‼️So, if I summarised correctly: - Everyone who had COVID-19 tends to have some lasting reduction in brain blood flow (CBF), mainly in frontotemporal areas – even if they feel 100% recovered. - In Post-COVID Condition (PCC) the decline is more pronounced in severity and more localised to right parieto-occipital regions, and this specific occipital reduction strongly tracks with fatigue. 😷Do you still want to get re-infected?

Well-meaning but misguided progressives in the West have swallowed the Islamic Republic’s propaganda. Millions of Iranians would trade places with you in a heartbeat—while you defend their oppressors.

Justice Alito explains, in a great video for @HooverInst, that he wishes SCOTUS had taken our cases to prevent racial discrimination against Asian American students in Fairfax and Boston. We do too.
