Trends in maternal mortality, severe maternal morbidity during delivery-related hospitalizations

JAMA Network Open

2023-06-22

(Press-News.org) About The Study: This study found that delivery-related mortality in U.S. hospitals decreased for all racial and ethnic groups, age groups, and modes of delivery during 2008 to 2021, likely demonstrating the impact of national strategies focused on improving maternal quality of care provided during delivery-related hospitalizations. Severe maternal morbidity prevalence increased for all patients, with higher rates for racial and ethnic minority patients of any age. Advanced maternal age, racial or ethnic minority group status, cesarean delivery, and comorbidities were associated with higher odds of mortality and severe maternal morbidity.

Authors: Dorothy A. Fink, M.D., and Deborah Kilday, M.S.N., of the Department of Health & Human Services in Washington, D.C., are the corresponding authors.

Unraveling the connections between the brain and gut

2023-06-22

CAMBRIDGE, MA -- The brain and the digestive tract are in constant communication, relaying signals that help to control feeding and other behaviors. This extensive communication network also influences our mental state and has been implicated in many neurological disorders. MIT engineers have now designed a new technology that can be used to probe those connections. Using fibers embedded with a variety of sensors, as well as light sources for optogenetic stimulation, the researchers have shown that they can control neural circuits connecting the gut and the brain, in mice. In a new study, the researchers demonstrated that they could induce feelings of fullness or reward-seeking ...

Parental cancer history and children’s unmet food, housing, and transportation economic needs

2023-06-22

About The Study: Parental cancer is associated with greater likelihood of food insecurity, unaffordability of housing and other necessities, and transportation barriers to medical care for minor children. Strategies to identify such children and address their needs are warranted. Authors: Zhiyuan Zheng, Ph.D., of the American Cancer Society in Atlanta, is the corresponding author.

Risk of cardiovascular events among patients with head and neck cancer

2023-06-22

About The Study: The results of this study suggest that in head and neck squamous cell carcinoma (HNSCC), the burden of suboptimally controlled cardiovascular (CV) risk factors and incident risk of stroke and heart attack are substantial. Modifiable CV risk factors are associated with risk of adverse CV events, and these events are associated with a higher risk of death. These findings identify populations at risk and potentially underscore the importance of modifiable CV risk factor control and motivate strategies to reduce CV risk in HNSCC survivorship care. Authors: Lova Sun, M.D., ...

Physicists discover a new switch for superconductivity

2023-06-22

Under certain conditions — usually exceedingly cold ones — some materials shift their structure to unlock new, superconducting behavior. This structural shift is known as a “nematic transition,” and physicists suspect that it offers a new way to drive materials into a superconducting state where electrons can flow entirely friction-free. But what exactly drives this transition in the first place? The answer could help scientists improve existing superconductors and discover new ones. Now, MIT physicists have identified the key to how one class of superconductors undergoes a nematic transition, and it’s in surprising contrast to what ...

Studying herpes encephalitis with mini-brains

2023-06-22

The herpes simplex virus-1 can sometimes cause a dangerous brain infection. Combining an anti-inflammatory and an antiviral could help in these cases, report scientists with the Rajewsky and Landthaler labs and the Organoid Platform at the Max Delbrück Center in Nature Microbiology. About 3.7 billion people — 67% of us — carry the herpes simplex virus-1 in our nerves cells where it lies quiescent until triggered by stress or injury. When activated, its symptoms are usually mild, limited to cold sores or ulcers in our mouth. Very rarely, the virus ...

New study shows children of parents with cancer history in US may be vulnerable to housing, food and financial hardship

2023-06-22

ATLANTA, June 22, 2023 – A new study by researchers at the American Cancer Society (ACS) found children of parents with a cancer history in the United States are more at risk of having unmet needs for housing, food, and other living necessities than their counterparts without a parental cancer history. The findings will be published today in the Journal of the American Medical Association (JAMA) Network Open. “Cancer is a life-threatening disease and parents with a history of cancer are often saddled with worry about paying for food, the ...

Never-before-seen way to annihilate a star

2023-06-22

Most stars in the Universe die in predictable ways, depending on their mass. Relatively low-mass stars like our Sun slough off their outer layers in old age and eventually fade to become white dwarf stars. More massive stars burn brighter and die sooner in cataclysmic supernova explosions, creating ultradense objects like neutron stars and black holes. If two such stellar remnants form a binary system, they also can eventually collide. New research, however, points to a long-hypothesized, but never-before-seen, fourth option. While searching for ...

Stellar demolition derby births powerful gamma-ray burst

2023-06-22

While searching for the origins of a powerful gamma-ray burst (GRB), an international team of astrophysicists may have stumbled upon a new way to destroy a star. Although most GRBs originate from exploding massive stars or neutron-star mergers, the researchers concluded that GRB 191019A instead came from the collision of stars or stellar remnants in the jam-packed environment surrounding a supermassive black hole at the core of an ancient galaxy. The demolition derby-like environment points to a ...

Einstein and Euler put to the test at the edge of the Universe

2023-06-22

The cosmos is a unique laboratory for testing the laws of physics, in particular those of Euler and Einstein. Euler described the movements of celestial objects, while Einstein described the way in which celestial objects distort the Universe. Since the discovery of dark matter and the acceleration of the Universe’s expansion, the validity of their equations has been put to the test: are they capable of explaining these mysterious phenomena? A team from the University of Geneva (UNIGE) has developed the first method to find out. It ...

Promoting high energy Na4MnCr(PO4)3 capable of three-electron reaction for SSSMBs

They published their work on June. 9 in Energy Material Advances. "The development of high safety and high energy density SIBs is imperative," said paper author Zhongyue Wang, lecture with the College of electronic and optical engineering & college of flexible electronics (future technology), Nanjing University of Posts and Telecommunications. "Currently, great progress has been made in sodium-ion batteries, but their energy density is still much lower than LIBs limited by the cathode." Wang explained that NASICON-type phosphate (NaxMM’(PO4)3, M, M' =transition metal Ti, V, Cr, Mn, Fe, Co and Ni) is regarded ...
