      Initial Assessment: Transthoracic echocardiography (TTE) is recommended at diagnosis to assess aortic valve anatomy, valve function, and thoracic aortic diameters. CT or MRI is reasonable for comprehensive anatomic assessment. [1]

      Surveillance Imaging: The choice depends on aneurysm location: [2]

      Aortic root/proximal ascending aorta: TTE can be used if measurements correlate well with CT/MRI

      Mid-ascending, arch, or descending thoracic aorta: CT or MRI is recommended

      MRI is preferred for long-term surveillance to avoid cumulative radiation exposure from serial CT scans [1][3]

      Surveillance Intervals

      Size-Based Recommendations: [2-4]

      <4.0 cm: Every 2-3 years if stable

      4.0-4.4 cm: Every 2 years

      4.5-4.9 cm: Annually

      5.0-5.4 cm: Every 6-12 months (consider optimization for repair)

      ≥5.5 cm: Surgical evaluation indicated

      Initial surveillance: Obtain follow-up imaging at 6-12 months after diagnosis to establish the growth rate. If stable, adjust interval based on size. [1]

      Growth rate considerations: Descending thoracic aneurysms grow faster than ascending aneurysms (mean 2.76 mm/year vs 1 mm/year overall). Growth accelerates exponentially above 4.5 cm diameter. [3-4]

    1. for - wicked problems - synthentic opiods coming to EU faster due to successful Taliban war on poppy industry

      summary - the new synthetic opiod "Nitazene" is being manufactured in China and replaces the banned fentanyl. It is 300x stronger than heroin. - Due to the Taliban's successful war on drugs that has stamped out 95% of the poppy production, EU drug addicts are turning to the far more deadly nitazine

    1. Zusammenfassender Artikel über Studien zu Klimafolgen in der Antarktis und zu dafür relevanten Ereignissen. 2023 sind Entwicklungen sichtbar geworden, die erst für wesentlich später in diesem Jahrhundert erwartet worden waren. Der enorme und möglicherweise dauerhafte Verlust an Merreis ist dafür genauso relevant wie die zunehmende Instabilität des westantarktischen und möglicherweise inzwischen auch des ostantarktischen Eisschilds. https://www.theguardian.com/world/2023/dec/31/red-alert-in-antarctica-the-year-rapid-dramatic-change-hit-climate-scientists-like-a-punch-in-the-guts
