Reexamining time from breast cancer diagnosis to surgery

JAMA Surgery

2023-03-01

(Press-News.org) About The Study: This case series study using the data of 373,000 patients from the National Cancer Database found that time from breast cancer diagnosis to surgery of greater than eight weeks was associated with worse overall survival. Time to surgery of greater than eight weeks may partly be associated with disadvantageous social determinants of health.

Oldest human genome from southern Spain

2023-03-01

An international team of researchers has analysed ancient human DNA from several archaeological sites in Andalucía in southern Spain. The study reports on the oldest genome to date from Cueva del Malalmuerzo in southern Spain, as well as the 7,000 to 5,000-year-old genomes of early farmers from other well-known sites, such as Cueva de Ardales. The Iberian Peninsula plays an important role in the reconstruction of human population history. As a geographic cul-de-sac in the southwest of Europe, it is on one hand considered a refuge during the last Ice Age with its drastic temperature fluctuations. On the other hand, it may have been one of the starting points for the recolonisation ...

The counting of nine billion trees could help manage climate credits and nature restoration

2023-03-01

Researchers from the University of Copenhagen and NASA have developed a method that has now mapped several billion trees and their carbon uptake in Africa’s Sahel region. In the future, the method could be used to monitor whether climate credit purchases have a positive effect on the number of trees and whether nature restoration is working. The purchase of indulgences for CO2 emissions is gaining steam among global corporations. Carbon offset credits allow companies to emit a given amount of CO2 in exchange for the greenhouse gas being neutralized elsewhere, in the form of trees planted or left unfelled. But with billions upon billions of trees across the planet, keeping track ...

New study unveils epigenetic ‘traffic lights’ controlling stop and go for gene activity

2023-03-01

A major new study in the journal Nature reveals a ‘traffic light’ mechanism controlling genetic activity within cells – a system which could potentially be targeted by cancer drugs already in development. The research describes how ‘epigenetic’ changes to the structure of DNA can act as a stop-go signal in determining whether a gene should be read. Unlike our genetic make-up, which is well understood, the world of epigenetics is still largely unexplored and referred to as the ‘dark matter’ of the genome. But the new findings answer a fundamental and longstanding question – how epigenetic proteins regulate the ...

New NASA DART data prove viability of asteroid deflection as planetary defense strategy

2023-03-01

NASA’s Double Asteroid Redirection Test (DART) was Earth’s first attempt at launching a spacecraft to intentionally collide with and deflect an asteroid as a planetary defense technique. On September 26, 2022, the DART spacecraft collided with a small asteroid moon called Dimorphos, which orbits a larger asteroid called Didymos. Neither asteroid posed a threat to Earth, but they represented similar celestial bodies that could one day approach and endanger the planet. In four papers published in the journal Nature on ...

This includes ...

Review of studies finds disparity in presumptive chlamydia and gonorrhea treatment rates despite CDC guidelines

2023-03-01

INDIANAPOLIS – A Regenstrief Institute-led review of studies on proactive health services for chlamydia and gonorrhea has found that rates of presumptive treatment -- antibiotics prior to laboratory test confirmation -- varies widely. The U.S. Centers for Disease Control and Prevention recommends presumptive treatment of individuals with symptoms of or known contact with these infections to decrease likelihood of secondary infections as well as poor outcomes. The healthcare settings of all 18 of the studies reviewed were within the U.S. and patients were age 14 and older. Presumptive treatment rates were found to ...

Chinese Medical Journal study identifies major risk factors of pulmonary tuberculosis in patients with pneumoconiosis in China

2023-03-01

Pneumoconiosis comprises a group of heterogeneous lung diseases resulting from the inhalation of mineral dust. It is an occupational hazard with significant economic and social implications. Notably, patients with pneumoconiosis have an elevated risk of contracting pulmonary tuberculosis (PTB). Unfortunately, pneumoconiosis has a strong presence in China. However, extensive population-based studies on the prevalence of PTB in patients with pneumoconiosis have not been conducted in China since almost three decades. To bridge this gap, a team of ...

National Comprehensive Cancer Network updates annual conference with new in-person venue, hybrid format, expert-led sessions, highlighted research perspectives, and small-group conversations

2023-03-01

PLYMOUTH MEETING, PA [March 1, 2023] — The National Comprehensive Cancer Network® (NCCN®) today announced the NCCN 2023 Annual Conference will debut a new hybrid format, including in-person events at a new venue. This marks the first time in three years that this premier oncology meeting will be held in-person, and the first-ever time at the Orlando World Center Marriott, starting on March 31. “We’ve heard from many people who learn better by being in the ‘room where it happens,’” said Robert W. ...

Moose can play a big role in global warming

2023-03-01

One of the biggest potential single sources of carbon emissions from wooded parts of Norway has four legs, weighs as much as 400-550 kg and has antlers. That’s right — moose can reduce carbon storage in clearcut sites equivalent to as much as 60 per cent of the annual fossil fuel carbon emissions from a region, a new study shows. “Moose are an ecosystem engineer in the forest ecosystem, and strongly impact everything from the species composition and nutrient availability in the forest,” said Gunnar Austrheim, an ecologist at the NTNU University Museum who was one of the study’s co-authors. “A grown animal can eat 50 kilograms ...

America on the move: How urban travel has changed over a decade

2023-03-01

A new Florida Atlantic University study on America’s urban travel trends shows important variations in travel behaviors across income, home ownership, ethnicity, gender, age, and life-cycle stages. The sixth in a series of studies compared changes in travel modes, trip frequency, trip distance and vehicle ownership among a range of socioeconomic groups using nationwide travel survey data since 1977. The most notable trend, published in the journal Transportation Research Part D, reveals that although private automobiles continue to be the dominant travel mode in American cities, the share of car trips has slightly and steadily decreased ...
