If you wear a Fitbit or a smartwatch, you may have noticed your HRV drop and your resting heart rate climb after COVID. Data from 1,475 people in the RECOVER cohort now confirm that pattern objectively - from passively collected sensor data🧵

🚨 🔥İkinci sıcak kubbe geliyor: Avrupa için cehennemin kapıları açık kaldı: Vur-Kaç yapmayacak, günlerce sürecek, "Omega Blokajı" Yolda! Meteoroloji modellerine düşen son veriler çok daha sinsi ve yıpratıcı bir tabloyu ortaya koyuyor: -Haziran sonundaki SICAK KUBBE’nin ardından, temmuz başında çok daha geniş bir alanı yutacak ve ilkinden çok daha uzun süre kalıcı olabilecek ikinci bir Sıcak Hava Kubbesi (Heat Dome) batı Avrupa üzerine kilitlenmeye hazırlanıyor -Haziran sonundaki ilk kubbe aşırı agresif ama nispeten kısa süreliydi. Ancak 7 - 10 Temmuz vadeli son ECMWF çıktılarına göre bu yeni sistem bir Atmosferik Blokaj (Omega) oluşturuyor. Yüksek basınç sistemi Avrupa'nın üzerinde adeta devasa bir "ısı kapağı" gibi çakılı kalabilir ve sıcak havayı günlerce (en az 6-9 gün) içeri hapsedebilir. -🔥 Kümülatif (Birikimli) Isı Tehdidi: İlk dalga batı Avrupa'daki toprağın nemini zaten tamamen kuruttu ve fırınladı. Şimdi nem kalmadığı için, bu yeni gelen kubbe yüzeyi çok daha hızlı ve acımasızca ısıtacaktır. Her gün bir önceki günden daha sıcak olacak! 🌡️ Modellerdeki Yeni Max Sıcaklık ve Rekor Beklentileri (7-10 Temmuz başlaması bekleniyor ) 🇪🇸🇵🇹 İspanya & Portekiz: Endülüs ve iç kesimlerde termometrelerin 44°C - 46°C bandına vurarak mutlak Temmuz rekorlarını tazelemesi bekleniyor. 🇫🇷 Fransa: Yeni kubbenin merkez üssü yine güneybatı Fransa. Yüzeyde 43°C - 45°C arası değerlerle yerel rekorlar tekrar sallantıda! 🇩🇪🇧🇪 Almanya & Benelüks: Isı adası etkisiyle iç kesimlerde sıcaklıklar 38°C - 41°C aralığına tırmanarak Temmuz ekstrem istatistiklerini yenileyebilir. 🇬🇧 İngiltere (Güney): Londra ve güney kıyılarında adayı felç edecek 34°C - 37°C arası bunaltıcı pikler öngörülüyor. ⚠️ Uluslararası Alarm: Günlerce yerinden kıpırdamayacak bu blokaj; Fransa, İspanya ve İtalya genelinde orman yangını riskini maksimuma çıkarırken, nehir su seviyelerini düşürecek ve enerji şebekelerini ciddi şekilde zorlayacak. İlk dalga bir şok etkisiydi, ikincisi ise tam bir yıpratma savaşına dönecek. Avrupa küresel ortalamanın iki katı hızla kavrulurken, Temmuz ayı meteoroloji tarihine geçmeye hazırlanıyor! (Météo-France ve küresel tahmin merkezleri (ECMWF & GFS) bu senaryo üzerinde %70'in üzerinde bir mutabakat sağlıyor. Uzmanlar, haziran sıcağıyla nemini tamamen kaybetmiş Avrupa topraklarının bu ikinci darbeyle çok daha kolay rekor kırabileceği konusunda hemfikir!") Bu veriler yeni. Uzun vadeli hava tahminleri yüzde yüz garanti değil , yaklaşmakta olan sıcaklık taarruzunun bozulup bozulmayacağını veya çok daha büyük bir felakete mi neden olacağını gün gün modellerin güncellenmesiyle göreceğiz . Dilerim ki bu yeni kubbe bozularak normallerde seyredecek sıcaklıklar yaşansın 🙏 #HeatDome #Heatwave #ECMWF #ClimateCrisis #ExtremeWeather #EuropeWeather

Researchers built a mouse with a human immune system to finally watch how human defenses fight COVID. They expected the virus to get wiped out. Instead, the human immune cells helped it spread from the lungs into other organs and muffled the body's own early alarm system🧵

It's hard to fathom what Europe will live next week. Thousands of records will be brutalized in Spain,France,UK,Benelux,Germany,Swiss,Austria and than the East Paris might record 4 consecutive days 40C UK will ridiculize its June national record Germany 10 days 37C+ This is CRAZY

Il est désormais attendu 42 à 45°C de la Bretagne (!!) jusqu'aux Pays de la Loire mercredi, avec des rafales pouvant atteindre 50 km/h et une humidité relative inférieure à 10 %. Dans ces conditions, il apparaît de plus en plus probable qu'un épisode majeur de Heat Wave Flash Drought (HWFD) (plus connu du grand public sous le nom d'« effet sèche-cheveux » ou de sécheresse éclair) se mette en place sur une superficie immense (carte 1). L'association d'une chaleur extrême, d'un air exceptionnellement sec et d'un vent soutenu provoque une accélération brutale de l'évapotranspiration et du dessèchement de la végétation. Les conséquences peuvent être très rapides : pertes foliaires massives, mortalité de jeunes plants particulièrement sensibles, stress sévère pour la faune et l'élevage, et risque d'incendie atteignant des niveaux extrêmes à très extrêmes (carte 2). L'ampleur des valeurs envisagées pour l'ouest de la France est difficile à appréhender. Voir de telles conditions s'étendre jusqu'à la Bretagne est tout simplement stupéfiant. En tant qu'agroclimatologue, je suis profondément sidéré par ce que les modèles continuent de simuler.

#Europe is entering the danger zone. 8°C above normal across most of the continent & 40°C+ lasting for days. Heat deaths are driven by prolonged exposure, not just peak temps. If this pattern persists all summer, we could see mortality levels worse than devastating 2003 heatwave.

If you’re in your 40s and haven’t had shingles, these findings are both encouraging and frustrating. For most of my career I’ve studied ways to preserve cognitive function as we age. Seeing evidence that shingles vaccination may reduce dementia risk is remarkable. It’s also a reminder that prevention matters. Dementia is devastating for individuals, families, and health systems, and we already lack the caregiving capacity needed for the growing number of cases. What makes these findings especially interesting is that shingles and other latent viruses can reactivate when the immune system is stressed. Researchers have also reported associations between SARS-CoV-2 infection and viral reactivation, as well as increased risks for a variety of neurological outcomes. Shingrix isn’t a time machine. It can’t undo existing neurological injury or disease processes. But if a relatively simple intervention can meaningfully reduce dementia risk, that’s the kind of preventive medicine we should be paying attention to. The bigger lesson may be that protecting brain health requires thinking seriously about infection, immunity, aging, and prevention long before symptoms appear.

Ebola outbreak zone cases up almost 40 percent in a week The Ebola outbreak in Congo that’s spread across parts of Africa has killed more than 200 people in its first month and is considered the worst known outbreak at this stage, the Africa Centres for Disease Control and Prevention (Africa CDC) said Thursday. Ebola cases have surged 38 percent since last week, spreading across 32 health zones in eastern Congo.

Long-term CMR Findings in Pediatric COVID-19 Related Myocarditis 🚨Even when KIDS 'fully recover' from COVID myocarditis, demonstrate normal heart function and have no symptoms, new CMR data shows PERSISTENT microvascular damage in the heart that refuses to go away!💔 ➡️A retrospective small USA single-center study analysed long-term cardiac magnetic resonance (CMR) findings in 21 paediatric patients (mean age 13.1 years, 57% male) with suspected COVID-19-related myocarditis or MIS-C, ➡️Thirty CMR studies were categorized as early (<30 days), mid-term (30–364 days), and long-term (≥365 days), with serial imaging in 8 patients (median follow-up 347 days), ➡️Diagnosis used the 2009 Lake Louise criteria (T2-weighted imaging for oedema, early gadolinium enhancement(EGE)for hyperaemia/capillary leak, and late gadolinium enhancement (LGE) for fibrosis/necrosis), ➡️Important findings: - Oedema resolved completely on long-term and serial follow-up imaging (15% early → 0%), - LGE declined markedly (46% early → 25% mid-term → 0% long-term) and persisted in only 13% (1/8) of serial cases, showing lateral wall predominance, - Pericardial effusions resolved fully (46% → 0%), - Biventricular systolic function remained normal on all follow-up scans, - In stark contrast, EGE remained persistently high across all timepoints: 77% early, 83% mid-term, and 80% long-term. Among patients with serial CMR, EGE persisted in 88% (7/8) despite resolution of oedema, LGE, and effusions, - 13% continued to meet Lake Louise criteria on follow-up: 1 out of the 8 children who had repeat heart scans (CMR) still showed enough abnormalities to be diagnosed with active myocarditis/ LGE (scarring), ➡️Limitations: well noted/single center/ larger prospective studies urgently needed! ➡️Over a median clinical follow-up of 20 months, there were no arrhythmias, heart failure symptoms, cardiac rehospitalizations, or mortality. Most CMR abnormalities improved with favourable medium-term outcomes, but persistent EGE was common. ‼️So, despite complete resolution of oedema, near-total disappearance of LGE and effusions, preserved ventricular function, and zero adverse clinical events, the near-universal persistence of EGE in these children reveals ongoing microvascular damage in the heart, a silent, enduring marker of residual hyperaemia and capillary leak that continues unabated beneath a facade of apparent recovery. This finding demands recognition that normal function and symptom-free status do not equate to myocardial health! → The microvascular injury persists as a potential long-term threat requiring vigilant, extended surveillance in paediatric COVID-19 myocarditis survivors. #AvoidSars2 #AvoidReinfections #ProtectChildren link.springer.com/article/10.100…

Not Good… 🦠Following infection, Ebola virus can survive unnoticed in the human body for months or even years, hiding in areas with little immune surveillance like the central nervous system. In doing so, it poses the danger of triggering an Ebola virus disease relapse or even a new outbreak.

New study. In some people, a mild case of COVID seems to leave a hidden edit in how their cells manage their own RNA - and it doesn't fully reset once the virus is gone. Another possible clue to why some bodies don't bounce back the same. 🧵
