The North Shore-LIJ Health System Department of Radiation Medicine presented a novel study to evaluate the reliability of different systems used by caregivers to assess toxicity for patients receiving radiation therapy. The study will be presented at the 55th Annual Meeting of the American Society of Therapeutic Radiation Oncology in Atlanta, GA.
During the course of radiation therapy, patients may experience reactions to their treatments. Typically, the severity of reactions is assessed by a radiation oncologist and nurse using a formal grading scheme. Research conducted by North Shore-LIJ's radiation oncologists evaluated the reliability of these grading systems by independent caregivers. The study assessed whether independent caregivers would assign the same grade to the same adverse reaction using a common grading scheme. Images of breasts that had undergone radiation in 30 breast cancer patients on skin care protocols were presented to radiation oncologists and nurses who were asked to assign grades independently based on their evaluation of the images and provide feedback explaining their choices. The assessments were then analyzed and the level of agreement among caregivers was determined using statistical methods.
As presented at ASTRO, the study determined that overall there was a significantly better agreement in the assessments based on the use of the Common-Terminology-Criteria-for-Adverse Events (CTCAE) scale, which was developed by the National Cancer Institute to standardize the assignment of grades across various caregivers. Analysis of the comments provided by the caregivers revealed a reliance on assessment criteria that was not necessarily explicit in the grading definitions.
"Establishing the reliability of the scale used to assess adverse reactions among different caregivers is an important step to enhance uniformity and consistency of the care to our patients," said Ajay Kapur, PhD, lead author of the study and director of medical physics research and education in the North Shore-LIJ Department of Radiation Medicine. "The specific grading scheme used must demonstrate a high level of reliability amongst various caregivers."
The study's senior author and chair of radiation medicine, Louis Potters, MD, said, "In order to deliver the highest quality of care to our patients, we all need to speak the same language. This study enhances our ability to provide Consistent care to all our patients and further validates the CTCAE grading system."

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
