Deep-learning-based anatomical landmark identification in CT scans

Deep-learning-based anatomical landmark identification in CT scans
2023-03-06
Millions of people around the world undergo some type of orthodontic treatment each year due largely to developmental deformities in the jaw, skull, or face. Computed tomography (CT) imaging is the go-to technique for surgeons when planning such treatments, especially surgeries. This is because CT provides 3D images of the bones and teeth, which helps the surgeon analyze complex cases in detail and determine the best treatment procedure based on that. During the CT scan, surgeons typically try to pinpoint specific anatomical landmarks in the images. These are distinct points in the human body that can be used as a reference to make measurements and assess a condition ...

The challenges of mining for electric-vehicle batteries

2023-03-06
In August 2022, Congress passed the Inflation Reduction Act (IRA). Signed by President Joe Biden, the legislation attempted to curb inflation, lower the deficit, and invest heavily into domestic clean energy. One aspect of the bill was setting a market value-based target for battery-critical mineral content in electric vehicles (EVs). By 2027, for an EV to be tax-credit eligible, 80 percent of the market value of critical minerals in its battery must be extracted or processed domestically or by US free-trade partners (FTPs).  While this goal is well-intended, there are reasons to believe the mandate is unreachable and could create new problems. In a commentary published ...

Iron & the brain: Where and when neurodevelopmental disabilities may begin during pregnancy

2023-03-06
The cells that make up the human brain begin developing long before the physical shape of the brain has formed. This early organizing of a network of cells plays a major role in brain health throughout the course of a lifetime. Numerous studies have found that mothers with low iron levels during pregnancy have a higher risk of giving birth to a child that develops cognitive impairments like autism, attention deficit syndrome, and learning disabilities. However, iron deficiency is still prevalent in ...

Long-term intermittent fasting reduces COVID-19 heart failure complications and death in patients with previous heart disease

Long-term intermittent fasting reduces COVID-19 heart failure complications and death in patients with previous heart disease
2023-03-06
Intermittent fasting, especially when done over the course of decades, can have positive effects on metabolic and cardiovascular health. Now, a new study by researchers at Intermountain Health in Salt Lake City finds that it may also add an extra layer of protection from heart-related COVID-19 complications in people who had already sought cardiac care. “We already know that regular fasting over long periods of time can lead to overall health improvements. Here we found that it may also lead to better outcomes in COVID-19 patients who required a cardiac catheterization,” said Benjamin Horne, PhD, director of cardiovascular and genetic epidemiology ...

Study finds residual inflammation after statin therapy strongly predicted cardiovascular events, death

2023-03-06
New evidence released today from a study of 31,245 patients already taking statin therapy indicates that inflammation may be a more powerful predictor of risk of future cardiovascular events—such as heart attack and stroke — than “bad” cholesterol. Treatments that aggressively lower vascular inflammation need to be incorporated into daily practice if doctors are to maximize patient outcomes, according to the study’s corresponding author, Paul Ridker, MD, a preventive cardiologist at Brigham and Women’s Hospital, a founding member of the Mass General ...

2023-03-06
It is well established that folic acid supplementation can significantly reduce the risk of birth defects, including neural tube defects like spina bifida, the most common birth defect of the central nervous system and the second most common of all structural birth defects. More than 80 nations, including the U.S. 25 years ago, have established mandated folic acid food fortification programs, which have been successful. “However, there is a lack of research on whether excessive folic acid intake has the potential ...

Geisinger study supports genetic testing for people with cerebral palsy

2023-03-06
DANVILLE, Pa. – A Geisinger meta-analysis of recent research on the genetics of cerebral palsy (CP) provides evidence that genetic testing should be offered as the standard of care for people with the disorder, similar to current recommendations for individuals with other neurodevelopmental disorders (NDD). The findings were published Tuesday in JAMA Pediatrics. Individual cases of CP—a condition that affects movement, balance and posture—have often been attributed to birth asphyxia, although recent studies show that asphyxia accounts for less than 10% of cases. A growing body of evidence suggests that a significant proportion of CP is caused by genetic changes, ...
