Brain tumour tissue can be hard to distinguish from normal brain during surgery. Neurosurgeons use their best judgment in the operating room but often must guess exactly where the edges of the tumor are while removing it.
Even the state-of-the-art imaging equipment in today
Engineers at the University of California, San Diego, have developed a mouth guard that can monitor health markers, such as lactate, cortisol and uric acid, in saliva and transmit the information wirelessly to a smart phone, laptop or tablet.
The technology, which is at a proof-of-concept stage, could be used to monitor patients continuously without invasive procedures, as well as to monitor athletes
The brains of people with epilepsy appear to react to music differently from the brains of those who do not have the disorder, a finding that could lead to new therapies to prevent seizures, according to research presented at the American Psychological Association
Researchers at Thomas Jefferson University showed that a simple questionnaire, evaluation and pulse-oximetry monitoring can lead to early detection of sleep apnea in patients hospitalized for congestive heart failure (CHF).
Whenever cardiac insufficiency or serious heart defects worsen, such deterioration is often associated with a loss of muscular mass and muscular strength. Scientists at the Charit
A recent study led by DCRI Fellow Jacob Doll found that approximately two-thirds of the patients who were referred to rehabilitation did not attend an initial session.
Cardiac rehabilitation programmes include a mixture of exercise regimens, health education, and cardiovascular risk reduction and medication adherence support. These programmes, which typically comprise 2 to 3 weekly sessions for a total of 36 sessions, are associated with improvements in lifestyle, functional capacity, and quality of life for older adults. Despite this, rates of referral and adherence have traditionally been low, particularly in older adults.
In this study, Doll and his colleagues used data from the National Cardiovascular Data Registry Acute Coronary Treatment Intervention Outcomes Network Registry and Medicare claims to identify 58,269 patients 65 years or older who had a heart attack between 2007 and 2010. Of these patients, 36,376 (62.4 percent) were referred to cardiac rehabilitation. Only 11,862 patients (32.6 percent) attended at least one rehab session during the year following hospital discharge. Of those who had not been referred, 1,795 (8.2 percent) attended at least one session.
Only about 5 percent of the patients completed all 36 sessions, even though the sessions are usually covered by insurance.
These findings, the study
Patients suffering from chronic cardiopulmonary diseases could soon have a solution to help them accurately monitor their health and warn doctors at the first sign of trouble.

Academics at Loughborough University hope to boost early detection rates of cancer in developing countries with their portable labinabriefcase that can operate even at high temperatures.
Believed to be the first kit of its kind dedicated to the portable measurement of cancer biomarkers, the concept is the brainchild of Dr Nuno Reis, a Lecturer in Chemical Engineering.
The number of people dying from cancer in developing countries is on the increase, partly due to steadily ageing populations, but also due to limited access to proper diagnostic tools. Cancer is a leading cause of death worldwide, accounting for over 8 million deaths per year, and 70% of the world
Robotically steering flexible needles can reach their intended target in tissue with sub-millimetre level accuracy. This has been demonstrated by the doctoral research of Momen Abayazid, who is affiliated with the research institute MIRA of the University of Twente. A major advantage of steering flexible needles is that one can avoid obstacles or sensitive tissues and can re-orient the path of the needle in real time as you insert the needle.
During many diagnostic and therapeutic procedures a needle is inserted into soft tissue, such as during biopsies, or inserting radioactive seeds in order to combat prostate cancer. In many of these operations the accurate positioning of the needle is of the utmost importance. In general, rigid needles with a relatively large diameter are used in these procedures. However, the drawback of these needles is that they cannot be manoeuvred when inserted into tissue and hence cannot avoid any obstacles. In addition, the tissue and organs deform during needle insertion. As a result, the needle often misses its target.
The University of Twente is has developed a robot-assisted system for steering flexible needles with an asymmetric tip. Such a needle naturally bends when inserted into tissue due to its asymmetric tip. By performing a sequence of insertions and rotations, one can steer the needle in complex three-dimensional paths. The needle is controlled by a robot and is tracked in real time using ultrasound images. This ensures that it is possible to adjust the needle
