The article proposes a computational model to account for the complex interaction between stimulus size, duration, and retinal cones-to-retinal ganglion cells ratio. The findings challenge the assumption of a constant critical number of retinal ganglion cells with respect to the enlargement of the critical area of summation with eccentricity in the macula, proposing instead a constant critical total retinal input. The research has implications for understanding perimetric sensitivity and modeling disease, particularly glaucoma.

The Clinician’s Roundtable on ReachMD podcast, sponsored by GRAIL, featured Dr. Vershalee Shukla, who discussed the implementation of multi-cancer early detection screening (MCED). Dr. Shukla highlighted the limitations of currently available cancer detection tools, including mammography, colonoscopy, and skin exams, which have low sensitivity and compliance rates. In contrast, MCED screening is a simple blood test that looks for DNA methylation patterns in the blood to detect cancers and indicate their origin. Patients who are at high risk, such as those with family histories of cancer, genetic predispositions, and patients over 50 years old, should consider MCED screening. Utilizing MCED screening has enriched Dr. Shukla’s program and improved early detection rates of rare and aggressive cancers. Dr. Shukla emphasized that education is a critical aspect of implementing MCED screening in clinical practice. Patients must understand that MCED screening is not a replacement for routine cancer screenings but rather an additive tool to detect rare and aggressive cancers. Staff must also be educated to counsel patients correctly and understand that a negative MCED result does not necessarily mean that the patient is cancer-free. The physical implementation of MCED screening is straightforward, requiring a simple blood draw, and the results can be […]

Getting a handle on the biochemical processes that govern how food is broken down and used within the body can be a daunting task for many, and even for those who understand it, monitoring with technology isn’t always possible. This is where Levels come into play. An instant metabolic analysis just a few hours after eating is only the beginning of the Levels experience; the app focuses on four major blood glucose levers in a gamified experience: diet, exercise, stress, and sleep. Dr. Lauren Kelley-Chew, Levels’ Head of Clinical Product, discusses all of this and more.

For the first time, Uber Health users, including healthcare providers and health plans, will be able to manage prescription delivery from any pharmacy in their service area via the same platform they use to coordinate patient transportation. This launch allows providers to offer a comprehensive suite of care solutions that extend beyond the four walls of a clinic and is intended to improve patient experiences and health outcomes.

When a pharmacy experiences a data breach, the incident may be expensive to fix, interfere with patient care, and lead to legal action. Pharmacies are a “treasure trove” of information for criminals because they hold financial and healthcare information, making them the golden goose for criminals. Everyone is a target, from big chains to tiny independent pharmacies. Experts offer guidance on how to maintain vigilance.

The smartwatch market generated approximately 38.6 billion US dollars in revenue globally in 2022, and growth is expected to continue. Over a hundred of these devices, ranging from AI ultrasounds to smart sleep trackers and ECG watches, have been tried and tested by the author. His “7+1” recommendations are listed here.
