Vad säger AI om effekterna av att spara in på kostnad för smittskydd (såsom luftrening, far UV, testning) idag, kontra framtida kostnader för en sjukare befolkning? Är det ett smart val ur samhällsekonomisk synvinkel?

Läkaren @AgnesWold blev en nagel i ögat på SR. Kontroversen visar vad som händer när vetenskapen får ge vika för det politiskt korrekta. Inom medicinen är det en farlig ordning. För när biologin inte har säkra svar är det öppna, nyfikna samtalet desto mer angeläget. Obekväma röster får inte tystna för att de väcker vrede. svd.se/a/e72geR/agnes-wold-p… via @SvDledare.

22 people with long COVID. Mild infection, no hospitalization, nearly three years out. Routine MRI clean - the radiologist found nothing. Their brains still perfuse measurably worse than matched controls. Not in one spot, but globally.🧵

Swedish study: “Overall, our findings suggest that impaired cerebral perfusion may contribute to the development of fatigue in PCC patients.” And a MRI misses it. #LongCovid Cognitive fatigue is related to reduced cerebral perfusion and sustain... sciencedirect.com/science/ar…

Steven Spielberg wears a respirator while being interviewed outside the opening of the Lucas Museum of Narrative Art on September 19, 2026. Respiratory protection doesn’t have to be unusual or disruptive. For many people, it remains a simple, everyday way to reduce the risk of airborne infection and help protect their health and the health of those around them. #MaskUp #COVID19 #COVID #PublicHealth #InfectionPrevention

Lab confirmed covid cases have more than tripled here in three weeks. And in my whatsapps today, more colleagues asking for cover because they're sick. One can't do a wedding on Friday - thinks she caught what she has from the bride at the rehearsal. 🙄

This is not quackery. It's not low quality. It's not junk science. It's not debated. It's detailed, exhaustive, thoroughly researched science: Covid infections increase your risk of a vast range of health problems. Vaccinations do not prevent that increase in risk. Having had Covid before does not prevent that increase in risk. The only thing that prevents the increase in risk is to *not catch Covid*. There's a wave now, so mask up.

One more totally fucking nuts graph for today, care of a request by @LeonSimons8. Not only is the current standard deviation for the Nino 3.4 sea-surface temperature above 4SD over the 1982-2011 mean for the first time on record, but no previous year even reached 3SD.

You're going to see a lot written about the PISA scores. Covid infections harm the brain. It's been established over and over and over and over again. These scores will keep falling as long as people keep getting infected with Covid.

Brain scans reveal that COVID-19 may leave a lasting physical imprint on the brain. A recent study found altered tissue structure and chemical imbalances in both long COVID patients and those who fully recovered from the virus. dlvr.it/TV2lcC

A massive spike in “perimenopausal/menopausal conditions” among Swedish women aged 30–44 since 2022. Must be those terrible Swedish lockdowns or 5G...

Long COVID-19 in children: a review of key information 🚨Possibly 1 in 4 children may develop Long COVID, even after vaccination 😡Paediatricians, WAKE-UP! WE NEED TO PROTECT OUR CHILDREN! #PREVENTION ➡️A Polish review needs your attention! ➡️Review information: 1. Definition LongC0vid: - WHO 2023 criteria, symptoms appearing ≤3 months after SARSCoV2 infection, lasting ≥2 months, and significantly affecting daily functioning (school, activity, development), - Symptoms are heterogeneous and multisystemic, 2. Prevalence: - Pooled estimate 25% (meta-analysis >80,000 children), - Rises to 29% in hospitalized cases, - Over 200 possible symptoms reported, 3. Common manifestations(Fig): - Fatigue (3–87%), headaches (3–80%), cognitive dysfunction/brain fog (2–81%), sleep disturbances (2–63%), mood disorders, - Age-specific patterns exist (younger children: rashes/behavioural changes. Adolescents: fatigue, concentration issues), 4. Risk factors: - Older age (adolescence), female sex, comorbidities (obesity, allergies), severe acute infection, poor pre-infection health, - One-third of cases occur without clear risk factors, 5. Pathophysiology(Fig): - Multifactorial, - Possible viral persistence, immune dysregulation/autoimmunity, autonomic dysfunction, gut dysbiosis, vascular/endothelial damage, 6. Diagnosis: - Challenging due to nonspecific symptoms, - Requires thorough differential diagnosis and exclusion of other causes, - No specific biomarkers, 7. Vaccination & reinfection: - Pre-infection vaccination shows protective effect in some studies, - Reinfections increase longC0VID risk even after 2–3 vaccine doses, - One Omicron-era study found similar symptom burden/severity at 12 months between primary infection and reinfection groups, - Vaccination status did not significantly alter risk, - Number of infections does not appear decisive(?). ➡️The review stresses the need for standardized definitions and longer-term controlled studies. ‼️So, evidence remains limited and inconsistent. While pre-infection vaccination likely reduces longC0VID risk, reinfections (even in vaccinated children) can still trigger comparable long-term symptoms to primary infection, suggesting vaccines do not reliably prevent or mitigate post-acute sequelae once infection occurs. This implies cumulative risk with repeated exposures and that current vaccines offer incomplete protection against longC0VID in the paediatric population. Given the high prevalence (~25%), nonspecific symptoms, and diagnostic challenges, reinfections could meaningfully add to the long-term health burden in children despite generally mild acute disease. The review itself highlights that data on vaccination/reinfection effects are inconclusive and require further rigorous investigation, a key limitation of the current literature. Clinically, this supports continued emphasis on infection PREVENTION (including vaccination) while recognising that longC0VID remains a real, if poorly understood, risk even in the vaccinated and reinfected with a possible major Health and QOL impact. #AvoidSars2 #AvoidReinfections #Vaccination #CleanAir termedia.pl/Journal/-127/pdf…

Explain this to me. We have entire careers built on showing that exercise, diet, sleep, and other health behaviors can modestly attenuate age-related neurodegeneration. The effects are often small—2% more hippocampal volume here, a little more cortical thickness there, improvements in functional connectivity, etc. And we celebrate it (rightfully). Millions of people exercise every day chasing those gains—including people living with Parkinson’s. But suggest wearing a mask to reduce repeated exposure to a virus with growing evidence of long-term neurological and cognitive consequences, and suddenly many of the same “health behavior” experts are like: “Yeah… I’m not doing that.” The disconnect is fascinating.
