Been fishing all my life. Learnt what I know, what I feel and what I love on rivers, beaches, forests, mountains and oceans.






The presumed upcoming El Nino will help cement and quantify global warming acceleration, showing that 2ºC global warming is likely to be reached in the 2030s, not at midcentury.

🧵 New study: Children, adolescents and young adults aged 4–25 years with Long COVID report high symptom burden. Reported scores were more severe compared with other pediatric chronic disease cohorts (eg, chronic pain, cancer, sickle cell disease, autism). academic.oup.com/ofid/article/1…

This is the first time in a month that I feel good enough to record a video but I know that I probably shouldn't. The only reason I'm wrestling with the idea, is because doing nothing is intolerable.

Angiographic and Electrocardiographic Characteristics of Patients With Non–ST-Segment Elevation Myocardial Infarction and COVID-19 🚨STEMI + COVID-19 is even WORSE than NSTEMI + COVID-19, but this new core-lab study shows NSTEMI + Covid-19 alone is already catastrophic! ➡️Sit down and avoid a MI while reading this: ➡️Remember and roughly put: NSTEMI: Subendocardial( inner heart layer) MI STEMI: A transmural( full thickness) MI ➡️ This Canadian retrospective core laboratory-adjudicated analysis of 155 patients with laboratory-confirmed COVID-19 and non–ST-segment elevation myocardial infarction (NSTEMI) (April 2020 until December 2023, 29.7% women, median age 67 years), ➡️Participant Vaccination Status: - 82.6% (128/155) had received a COVID-19 vaccine. - No data on timing relative to hospitalization, booster doses, prior infections, or reinfections were reported, ➡️Key Angiographic Findings: - High thrombus burden (grade 3–5) in 43.3% of cases, - 25% stent thrombosis among patients with prior stents, - Percutaneous coronary intervention (PCI) performed in 67 patients but unsuccessful in 22.3%, ➡️Key Electrocardiographic & Functional Findings: - Diffuse, nonlocalizing ST-segment changes, - ST elevation in aVR in 33%, - Conduction abnormalities in 19.4%, - Q waves in 16.9%, - Global systolic dysfunction in 32.3%, ➡️Clinical Outcomes: - In-hospital mortality: 8.4% (13 patients; 95% CI 4.5–13.9), - No in-hospital reinfarction or stroke, ➡️Direct Comparison to STEMI + COVID-19: The study explicitly states this NSTEMI mortality (8.4%) is lower than the NACMI registry’s 33% in-hospital mortality for STEMI + COVID-19, yet still markedly elevated versus pre-pandemic NSTEMI (3.5% in SWEDEHEART), confirming STEMI + COVID-19 outcomes were even worse, ➡️Interpretation: COVID-19 drives a shared prothrombotic/inflammatory phenotype across both NSTEMI and STEMI, but even NSTEMI still shows catastrophic angiographic and procedural failure rates. ‼️Compared with historical pre-pandemic NSTEMI cohorts, this population shows markedly higher mortality and lower PCI success rates. This is the first core-laboratory description of angiographic and ECG characteristics in NSTEMI patients with concurrent COVID-19, ‼️This core-lab study proves that even with 82.6% COVID-19 vaccination and zero reported reinfection data, concurrent infection turns NSTEMI into a diffuse thrombotic catastrophe with 8.4% mortality (more than double historical, 2× the 3.5% SWEDEHEART pre-pandemic rate) and 22.3% PCI failure (7× the pre-pandemic 3.2% rate). STEMI + COVID-19 results were even worse (33% mortality in NACMI), ‼️Sadly, the study does not mention or recommend any treatment options, anticoagulation strategies, antiplatelet intensification, PCI timing adjustments, or other interventions to reduce thrombus burden, PCI failure, or mortality. Why, because it remains the topic of heightened discussions as science remains unsettled! Meanwhile: #AvoidSars2 #AvoidReinfections sciencedirect.com/science/articl…
