I have a pt who has lipedema. There are varying degrees of lipedema and it can actually be painful/disfiguring, but health insurance won't cover liposuction to treat it because liposuction is considered "cosmetic." I referred my pt to a plastic surgeon, who can hopefully write a letter of medical necessity so she can get lipo covered. She has tried conservative management including lymphatic drainage massage and compressive devices without much benefit. If a doctor is saying a certain treatment is needed, then the insurance company needs to just cover the damn treatment!
I just saw a video someone posted about it on tiktok. Someone in the comments mentioned pycnogenol, which is a European pine bark extract that is supposed to have anti-inflammatory effects and may help with lipedema.

Across three preregistered studies, participants interacting with sycophantic AI became more convinced of their own rightness and less willing to repair relationships. Yet at the same time, participants rated sycophantic AI models as higher quality, more trustworthy, and more desirable for future use, which may explain why this behavior has persisted despite its harmful impacts.

I have a female pt who is taking labetalol 100 mg bid. She used to take either HCTZ or chlorthalidone, but switched to labetalol when she was trying to become pregnant. She ended up not getting pregnant and then continued to take the labetalol since then. So I want to switch her to HCTZ. Beta blockers should not be abruptly discontinued because that can cause rebound HTN. So I will decrease her labetalol to 100 mg daily x1 week while at the same time taking HCTZ 12.5 mg a week. I never learned any specific way to taper off a beta blocker, but a quick search does say to decrease the dose by 25 to 50% 1 week at a time, so I think this is a good taper regimen.
The Invisible Technology Behind Access Cards, Toll Gates & Smart Tracking
Have you ever wondered how an office access card unlocks a door in seconds, how vehicles pass through automated toll gates without stopping, or how warehouses keep track of thousands of products in real time? The answer lies in Radio Frequency Identification (RFID)—a technology that has become an essential part of modern automation and connected systems.
RFID uses radio waves to identify and exchange data between a tag and a reader, enabling fast, contactless communication without requiring direct line-of-sight. Unlike traditional barcode systems, RFID can read multiple tags simultaneously, making it ideal for applications where speed, accuracy, and automation are critical.
How RFID Works
A typical RFID system consists of three main components:
RFID Tags – Small electronic devices attached to objects, products, ID cards, or equipment.
RFID Readers – Devices that transmit and receive radio signals to communicate with tags.
Software & Databases – Systems that process, store, and analyze the collected information.
When an RFID tag enters the reader's range, it transmits its unique identification data, allowing the system to instantly recognize and track the tagged item.

What Would You Build With an AI Supercomputer the Size of Your Hand?
A few years ago, if you wanted to build an AI-powered robot, a real-time object detection system, or an autonomous machine, you needed expensive hardware, powerful servers, and a budget that most hobbyists and startups simply didn't have.
Today, that's no longer the case.
The NVIDIA Jetson Orin Nano 8GB is one of those products that makes you stop and realize how far technology has come. This tiny module delivers incredible AI computing power in a form factor small enough to fit inside robots, drones, industrial systems, and edge devices.
What's exciting isn't the specifications themselves-it's what those specifications enable.
Imagine a robot that can recognize objects and navigate its surroundings without relying on cloud services. Imagine a security camera that understands what's happening in real time instead of just recording footage. Imagine a machine that can detect defects on a production line, identify anomalies, and make decisions instantly.
These aren't futuristic concepts anymore. They're projects that developers, students, startups, and makers are building right now.
The rise of edge AI is changing everything. Instead of sending data to distant servers and waiting for a response, devices can process information locally, making them faster, smarter, and more reliable. That's exactly where platforms like the Jetson Orin Nano shine.
What makes this particularly interesting for makers is that it lowers the barrier to entry. A small team-or even a single developer working from a home workshop-can now experiment with computer vision, machine learning, robotics, and AI applications that were once reserved for large organizations.
The question isn't whether AI will become part of future products.
The question is: what will you build with it?
An autonomous robot?
A smart surveillance system?
An AI-powered drone?
A next-generation industrial solution?
We're curious to know.
Bring incredible new capabilities to millions of small, power-efficient AI systems.
