Image: Harvard researchers have shown how ultrasound can temporarily disrupt an alginate hydrogel, which is held together by calcium ions (black dots) that are bound to acid chains (yellow). The gel self-heals when the ultrasound stops (Photo courtesy of the Wyss Institute and Harvard SEAS).

Ultrasound and Self-Healing Hydrogels Noninvasively Deliver Targeted Chemotherapy

Modern drug-delivery systems used to administer chemotherapy to cancer patients typically release a constant dose of the drug over time. But a new study challenges this gradual approach and offers a unique way to locally deliver the drugs “on demand.”   More...

Image: An axial CT scan slice through the heart (red) of a patient with Hodgkin lymphoma involving the mediastinum. On the left is the X-ray plan and on the right is the proton plan. The dark blue line in both represents the tumor and target area for the radiation. The green line represents the volume of the body receiving 95% of the total prescribed dose of radiation, while the light blue line reflects the volume of the body receiving 10% of the total prescribed radiation dose. As is apparent, with conventional radiation (left), the X-rays deposit more radiation in the heart and breasts than the proton plan. In fact, the proton plan reduced the mean dose to the heart by more than 50% and the mean dose to the breast by 70%. For this reason, it’s believed that Hodgkin lymphoma patients will have a much lower risk of heart disease and second malignancy with proton therapy than what’s been observed in the past with conventional radiation therapy (Photo courtesy of the University of Florida Proton Therapy Institute).

Proton Therapy Provides Safe, Long-Term Treatment for Hodgkin Lymphoma

In spite of various successes in treating patients with Hodgkin lymphoma, many patients suffer from the late effects of radiation therapy and chemotherapy treatment, including the possible onset of breast cancer or heart disease.   More...

Risk Profiling Used with Mammography Diagnosis Should Reduce Number of Missed Tumors

A new approach to reading mammograms that takes into account a woman’s health risk profile would reduce the number of tumors missed, and in addition, decrease the number of false-positive findings, according to recent research.   More...

Alliance Established to Provide Cloud-Based Healthcare Information Technology Platform

A strategic alliance has been established to offer an open, cloud-based healthcare platform. The new technology will enable medical device and data interoperability—the collection of data and subsequent analysis to enhance clinical decision making by professionals and enabling patients to take a more active role in managing their health.  More...
