Leveraging Preexisting Cardiovascular Data to Improve the Detection and Treatment of Hypertension: The NOTIFY-LVH Randomized Clinical Trial

From JAMA Cardiol ogy: A centralized, population health coordinator-led notification and clinical support pathway improved the initiation of antihypertensive therapy in patients with left ventricular hypertrophy.


Despite the recognition that poorly controlled hypertension leads to adverse cardiovascular events, there are often barriers in care systems that contribute to substandard recognition and treatment.19 Notably, prior work employing trained nonphysicians focused on closing gaps in cardiovascular disease management has yielded significant improvements in disease-specific metrics using remote, centralized interventions.20-25 Similarly, there is a growing body of evidence demonstrating the effectiveness of clinician-directed support systems—often in the form of “nudges”—that have made meaningful advances in a variety of clinical outcomes.26,27 Whether a methodologic approach combining clinician nudges with the support of trained nonphysicians can be applied to LVH-associated diseases—including hypertension—is unknown.

Accordingly, the NOTIFY-LVH pragmatic randomized clinical trial28 sought to determine whether potentially underutilized echocardiogram data could be leveraged to improve patient care by augmenting the traditional ambulatory care framework. Specifically, this study tested whether a centralized clinical support pathway targeting clinicians of patients with LVH on their prior echocardiograms would increase the rate of treatment for hypertension and the earlier diagnosis of LVH-associated diseases.

Dangerous Fungal Infection Sees a Dramatic Increase in US Hospitals

Cases of the fungal infection Candida auris are rising rapidly and coming from more sources too, a new US study reveals.

C. auris was first reported in the US in 2016 and is considered an “urgent antimicrobial resistance threat” in hospitals, according to the Centers for Disease Control and Prevention (CDC).

Focusing on a large health system in Miami, Florida, the new research found that reported clinical cases had risen from 5 in 2019 to 115 in 2023 – a considerable jump of 2,200 percent in four years.

NASA continues BioNutrients space-fermented food research

NASA’s BioNutrients series of experiments is testing ways to use microorganisms to make nutrients that will be needed for human health during future long-duration deep space exploration missions.

Some vital nutrients lack the shelf-life needed to span multi-year human missions, such as a mission to Mars, and may need to be produced in space to support astronaut health. To meet this need, the BioNutrients project uses a biomanufacturing approach similar to making familiar fermented foods, such as yogurt. But these foods will also include specific types and amounts of nutrients that crews will be able to consume in the future.

The first experiment in the series, BioNutrients-1, set out to assess the five-year stability and performance of a hand-held system—called a production pack—that uses an engineered microorganism, yeast, to manufacture fresh vitamins on-demand and in space.

Researchers identify mutations that can lead to resistance to some chemotherapies

Investigators at Mass General Brigham have uncovered how resistance to chemotherapies may occur in some cancers. Researchers focused on a pathway that harnesses reactive oxygen species (ROS) to kill cancer cells. The study found that mutations to VPS35, a key player in this pathway, can prevent chemotherapy-induced cell death. These results, published in Nature, could help pinpoint treatment-resistant tumors.

“ROS play an important role in healthy and diseased cells, but pathways that sense and control cellular ROS levels are not well understood,” said corresponding author Liron Bar-Peled, Ph.D., of the Krantz Family Center for Cancer Research at Mass General Cancer Center (MGCC), a member of the Mass General Brigham health care system. “A clearer understanding of ROS could help us understand why chemoresistance occurs in some cases.”

Low concentrations of ROS are required for normal cell signaling, but higher levels of ROS can damage cells and contribute to diseases such as cancer and neurodegeneration. Researchers know that mitochondria play an important role in ROS production, but it has been unclear if ROS-sensing proteins influence the mitochondria. If they do, this could impact responses to some anti-cancer treatments.

Study identifies gut sensor that propels intestines to move

After every meal, the intestines perform an action called peristalsis—moving food through their hollow interiors with coordinated contractions and relaxations of the smooth muscle.

For more than a century, scientists have known that nerve cells in the gut propel the colon to move, allowing the organ to perform its life-sustaining function. But exactly how these intestinal nerve cells do their job has remained elusive.

Now a new study led by researchers at Harvard Medical School and the Icahn School of Medicine at Mount Sinai has identified the mechanism behind this phenomenon, showing that the gut’s motility is altered by exercise, pressure, and inflammation.

Chewing Gum Releases Hundreds of Microplastics In Your Mouth, Study Finds

Chewing gum releases hundreds of tiny plastic pieces straight into people’s mouths, researchers said on Tuesday, also warning of the pollution created by the rubber-based sweet.

The small study comes as researchers have increasingly been finding small shards of plastic called microplastics throughout the world, from the tops of mountains to the bottom of the ocean – and even in the air we breathe.

They have also discovered microplastics riddled throughout human bodies – including inside our lungs, blood and brains – sparking fears about the potential effect this could be having on health.

Scientists reveal neuronal calcium oscillations involved in tissue communication

Mitochondria play a crucial role in maintaining energy balance and cellular health. Recent studies have shown that chronic stress in neuronal mitochondria can have far-reaching effects, not only damaging the neurons themselves but also influencing other tissues and systemic metabolic functions.

A new study led by Dr. Tian Ye’s research team at the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences (CAS) reveals that chronic mitochondrial stress in neurons promotes serotonin release via TMBIM-2-dependent calcium (Ca²⁺) oscillations, which in turn activates the mitochondrial unfolded protein response (UPRmt) in the intestine. The findings are published in the Journal of Cell Biology.

The researchers found that TMBIM-2 works in coordination with the plasma membrane calcium pump MCA-3 (a PMCA homolog) to regulate synaptic Ca²⁺ balance, sustaining persistent calcium signaling oscillations at neuronal synaptic sites.
