Fracture risk among living kidney donors 25 years after donation

About The Study: This survey study found a reduced rate of overall fractures but an excess of vertebral fractures among living kidney donors compared with controls after a mean follow-up of 25 years. Treatment of excess vertebral fractures with dietary supplements such as vitamin D3 may reduce the numbers of vertebral fractures and patient morbidity. Authors: Rajiv Kumar, M.B.B.S., of the Mayo Clinic in Rochester, Minnesota, is the corresponding author.

Contrasting characteristics and outcomes of sports-related and non–sports-related traumatic brain injury

About The Study: In this study of 4,360 patients with traumatic brain injury (TBI), functional limitations six months after injury were common after sports-related TBI, even mild sports-related TBI. Persisting impairment was evident in the sports-related TBI group despite better recovery compared with non–sports-related TBI on measures of mental health and post-concussion symptoms. These findings caution against taking an overoptimistic view of outcomes after sports-related TBI, even if the initial injury appears mild. Authors: Lindsay Wilson, ...

Syphilis-like diseases were already widespread in America before the arrival of Columbus

Researchers at the Universities of Basel and Zurich have discovered the genetic material of the pathogen Treponema pallidum in the bones of people who died in Brazil 2,000 years ago. This is the oldest verified discovery of this pathogen thus far, and it proves that humans were suffering from diseases akin to syphilis – known as treponematoses – long before Columbus’s discovery of America. The new findings, published in the scientific journal Nature, call into question previous theories concerning the spread of syphilis ...

Global groundwater depletion is accelerating, but is not inevitable

(Santa Barbara, Calif.) — Groundwater is rapidly declining across the globe, often at accelerating rates. Writing in the journal Nature, UC Santa Barbara researchers present the largest assessment of groundwater levels around the world, spanning nearly 1,700 aquifers. In addition to raising the alarm over declining water resources, the work offers instructive examples of where things are going well, and how groundwater depletion can be solved. The study is a boon for scientists, policy makers and resource managers working to understand global groundwater dynamics. “This study was driven by curiosity. We wanted to better understand the state of global ...

A large percentage of European plastic sent to Vietnam ends up in nature

Despite strict EU regulations on plastic recycling, there is little oversight on plastic waste shipped from the EU to Vietnam. A large percentage of the exported European plastic cannot be recycled and gets dumped in nature. That is what new research led by Utrecht University’s Kaustubh Thapa has found. Following the recycling path About half of Europe’s plastic waste is exported to a number of countries in the Global South, including Vietnam.

Ultrasounds can help predict the risk of preterm births, new research shows

Researchers have developed a way to use ultrasound to predict whether a pregnant person is at risk of delivering a baby prematurely, which occurs in upward of 10% of pregnancies in the U.S. The new method — the result of more than 20 years of collaboration between researchers in nursing and engineering at University of Illinois Chicago and University of Illinois Urbana-Champaign — measures microstructural changes in a woman’s cervix using quantitative ultrasound. The ultrasound method works as early as 23 weeks into a pregnancy, according to the research, which is published in ...

Exposure to flame retardants linked to premature birth, higher birth weight

(SACRAMENTO, Calif.) — In the largest study of its kind, researchers at UC Davis Health found that exposure to organophosphate ester flame retardants during pregnancy was associated with preterm birth, especially among females. The chemicals were also linked to higher birth weight, a concern for increased obesity risk. The major new research study was published in Environmental Health Perspectives. “The importance of this study lies in unraveling the potential impact of exposure to environmental chemicals during pregnancy on fetal development. Our findings guide our understanding of how these chemicals may be silently seeding lasting challenges ...

How a protein fights off bacteria

The human immune system is constantly fending off a wide range of invaders – a feat that requires a diverse array of cellular troops and molecular weaponry. Although a great deal is already known about immune defense cells and the strategies they employ, many molecular details have remained elusive. Now a research team led by Professor Oliver Daumke, a lab head at the Max Delbrück Center, has managed to unravel the main activation mechanism of GBP1, a protein that plays a pivotal role in combating certain bacteria.

Death rate higher than expected for patients with functional, nonepileptic seizures

The death rate for patients with functional, nonepileptic seizures is higher than expected, with a rate comparable to epilepsy and severe mental illness, a Michigan Medicine-led study finds. A team of researchers reviewed data from 700 patients who were diagnosed with functional seizures, also called psychogenic or nonepileptic seizures, between 2014 and mid-2023 and followed for a median of 15 months. It is the largest study of its kind in the United States, matching international studies in Australia, Denmark, Sweden and the United Kingdom, all of which have nationalized health care systems.

New study unveils how plants control the production of reactive oxygen species

Reactive oxygen species (ROS) are highly reactive molecules containing oxygen. These compounds, which are normal byproducts of biological processes in all living organisms such as aerobic respiration as well as photosynthesis, are highly toxic. In most cases, ROS damage cellular machinery and can trigger a harmful stress response if their levels are not kept in tight check; this is why antioxidants are an important part of our diet. However, over the past few decades, scientists have discovered that ROS are often intentionally ...

The fountain of youth is … a T cell?

The fountain of youth has eluded explorers for ages. It turns out the magic anti-aging elixir might have been inside us all along. Cold Spring Harbor Laboratory (CSHL) Assistant Professor Corina Amor Vegas and colleagues have discovered that T cells can be reprogrammed to fight aging, so to speak. Given the right set of genetic modifications, these white blood cells can attack another group of cells known as senescent cells. These cells are thought to be responsible for many of the diseases we grapple with later in life. Senescent cells are those that stop replicating. As we age, they build up in our bodies, ...

Infants born to COVID-infected mothers have triple the risk of developing respiratory distress

New UCLA-led research finds that infants born full term to mothers who were infected with COVID-19 during pregnancy had three times the risk of having respiratory distress compared with unexposed infants, even though they themselves were not infected with the virus. The risk was significantly lower when the mothers infected during pregnancy were previously vaccinated. The researchers found that in-utero exposure to SARS-CoV-2 sparked an “inflammatory cascade” in the infants, increasing the risk of a breathing disorder that most often ...

Chemotherapy becomes more efficient when senescent cells are eliminated by immunotherapy

Barcelona, 24 January 2024 – Cancer treatments, including chemotherapy, in addition to killing a large number of tumour cells, also result in the generation of senescent tumour cells (also called “zombi cells”). While senescent cells do not reproduce, they do, unfortunately, generate a favourable environment for the expansion of tumour cells that may have escaped the effects of the chemotherapy and eventually result in tumour regrowth. An international team of researchers led by Dr. Manuel Serrano at IRB Barcelona have described how cancer cells that have become senescent after ...
