A team led by Kathryn J. Ruddy, MD, MPH, and Dr. Ann H. Partridge, MD, MPH, surveyed 585 women recently diagnosed with breast cancer at or under the age of 40 years. This work was conducted at the Dana-Farber Cancer Institute in Boston, MA, where Dr. Partridge works. Dr. Ruddy is currently working at the Mayo Clinic in Rochester, MN.
The investigators found that 80 percent of the women detected their own breast abnormalities. Among women with self-detected breast cancers, 17 percent experienced a delay of at least 90 days before they visited a health care provider for an evaluation, and 12 percent reported a delay of at least 90 days between that visit and their diagnosis. Women with poorer financial status were more likely to experience a delay between detecting an abnormality and visiting a health care provider.
"Because we discovered that women who are less financially comfortable are more likely to delay seeking medical attention for breast abnormalities that later are diagnosed as breast cancer, it appears that economic disparity may be an important consideration in future development of interventions to reduce delays," said Dr. Ruddy. "The findings may lead to research focusing on whether reducing copays and 'hidden' costs of seeking medical care—such as parking charges, child-care expenses, and lost wages—may improve the timeliness of diagnosis in this population."
The authors also noted a non-significant trend toward more advanced disease in women who experienced a delay between seeing a health care provider and receiving a diagnosis. But because substantial delays only impacted a minority of women who detected their own breast abnormalities, they concluded that factors besides delays—such as tumor biology—are likely more influential on breast cancer outcomes in most cases.

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...
