We would argue that the @dr_larryi method is superior because you can get an actual right atrial pressure value not just dilated or not dilated. In patient with large AP chest diameter, neck utlrasound alone will underestimate right atrial pressure.
sciencedirect.com/science/ar…
#POCUS, or point-of-care ultrasound, can assess the internal jugular vein to estimate #JugularVenousPressure as an approximation of right atrial pressure. Jugular venous pressure can help identify volume overload using ultrasound assessment of the neck vessels.
To assess #JugularVenousPressure with #POCUS, the patient is positioned with the head of bed elevated and the linear probe is placed above the clavicle between the bellies of the sternocleidomastoid muscle. The vertical height from the sternal angle to the point where the internal jugular vein tapers is measured to calculate jugular venous pressure.

Physics is hard to visualize through static images alone, so I turned my 174 pages of high school physics notes into an interactive website.
It covers mechanics, electricity, and magnetism, breaking down complex concepts into intuitive visualizations, real-world scenarios, and interactive problems.

Ever wondered why a coronary occlusion gives the ECG it does?
Block any part of the coronary circulation on a 3D heart and watch the 12-lead (and the echo!) evolve.
Free for learning and teaching. Have fun!

In January 2025 my mom’s lung cancer spread to her brain. The drug with the best chance of helping her was approved in China but not here.
A doctor told me, almost as an aside, that if she were Chinese she could buy it at a pharmacy.
So I flew to Shanghai and came home with 26 boxes in my luggage. That was 19 months ago. My mom is still here, still working, and in her words has had an amazing three years.
The drug was approved in China in 2023. The FDA approved it in July 2025. It still is not for sale here. I know of at least 30 Americans who have made the same trip.
I have been scared to tell this story because I worried it could cost my mom access to the medicine keeping her alive. But the problem matters more than my silence. These drugs need to be developed and available here, and that means FDA reform.
Art Allen at KFF Health News told our story this week. It also ran in The Washington Post.

A new Perspective suggests that medical education must adapt as AI shifts clinical expertise from unaided cognitive performance toward the ability to evaluate, supervise, and appropriately defer to increasingly capable AI systems. Learn more: nejm.ai/4ybNSiw
ALT This figure shows a hypothetical clinical interface in which AI generates diagnostic and management recommendations while the physician evaluates their appropriateness, incorporates patient priorities, and judges when to defer or intervene. Displayed findings and confidence estimates are illustrative.

This is how a pathologist can now discuss slides and analyses with a multimodal pathology foundation model that connects whole-slide image representations with pathology reports and clinical concepts!
(The music is loud; feel free to mute it.)
"Here we present WILSON, a vision--language foundation model that represents whole-slide images and multi-slide cases as single multi-magnification composite images, trained on approximately 189k slides from Mayo Clinic spanning 42 organs and 829 diagnostic entities using pathology reports as supervision."
It could serve as an interactive AI assistant for pathologists!

A new era in the rapid diagnosis of STEMI/STEMI equivalents has begun. Rapid diagnosis of ACS that needs immediate, emergent intervention can only be done by the ECG. FDA authorization for the queen of hearts. “deNovo “ means it is the first device of its kind in the world.
🇺🇸 The #FDA has granted De Novo authorization to Queen of Hearts™, our AI ECG model for detecting acute coronary syndrome events, which can include #STEMI and STEMI equivalents and require urgent cardiologist activation.
A defining milestone for Powerful Medical.

🚨New science alert!
PAWP or LVEDP ... which better predicts outcomes?
Using simultaneous invasive hemodynamics at rest & during exercise, this study found that PAWP better reflected hemodynamic abnormalities & predicted adverse HF outcomes. 🫀

Thanks for following my cancer journey, it has been quite the ride! I’m 16 months cancer free now. I view two people as my cofounders on the journey of going ‘founder mode’ on my cancer. These are Jose M. Mejia Oneto, who was in my YC batch of W15 with Shasqi doing cancer therapies, and became my best friend! And @JAC0BSTERN who I met through Jose and who left his job in biotech to become ‘CEO of my health’. After we made progress on my disease we started creating companies to make the latest scientific advances more accessible to others. We’ve started 15 companies in the last year and a half under the Even One Ventures umbrella, see evenone.ventures/ for more information.

Tennis player, 30s
Forceful forehand with rapid thoracic rotation 2 years ago - immediate stabbing thoracic pain
Aggravated by L rotation, TSp extension, lying supine / rolling over in bed, deep inspiration
Pain now become more diffuse, symmetrical, paraspinal
Described as 'burning'
MRI normal
POCUS video -
Subtle degenerative changes at left T7 costotransverse joint - correlates with area of maximal pain (notable paraspinal hyperalgesia even with very gentle probe pressure)
US guided LA / CSI injection abolished pain (patient stated 'thats my pain!' when the needle tip hit the joint) on repeat clinical testing & patient's own functional tests post procedure
Pearls -
1. As always the history and exam trumps everything - rotation mechanism of injury, rotational provocation, rib compression, inspiration..... it has to be rib joint related
2. MRI often unhelpful when assessing the small joints in detail - CT better.
POCUS can pick up subtle degenerative / calcific changes once the pain epicentre has been identified with systematic palpation
2. Paraspinal muscle over-activity and spread of pain (which can take on a 'neural' quality) is almost inevitable secondary to the underlying primary issue / injury - don't be distracted by this.

FDA approved daraxonrasib….
One of oncology’s oldest walls just cracked…
This is not simply a new pancreatic cancer drug.
It is a reminder that even “undruggable” biology can become treatable with persistence.
Daraxonrasib doubled median OS vs chemotherapy in RAS G12 metastatic pancreatic cancer: 13.2 vs 6.6 months.
A remarkable ASCO moment.

Pericardial effusions have long been described in millimeters.
But when the clinical question is fluid burden, a single linear dimension may not be enough.
In our new JASE editorial with David Dudzinski, we discuss the practice-changing work by Kane et al. and the accompanying tutorial, which challenge us to rethink how we quantify pericardial effusions by echo.
The key shift:
From a single maximal width
to a more integrated assessment of volume, distribution, phenotype, and physiology.
Milliliters may bring us closer to the anatomic truth.
But tamponade remains a physiologic diagnosis.
