An arthroscopic near infrared spectroscopic probe for evaluation of articular cartilage and subchondral bone structure and composition was developed as part of a Ph.D. thesis at the University of Eastern Finland. The probe enables enhanced detection of cartilage injuries, as well as evaluation of the integrity of the surrounding tissue. The availability of comprehensive information on the health of joint tissues could substantially enhance the treatment outcome of arthroscopic intervention.
Adults go to the doctor roughly three times a year.1 During their visit, vitals are taken such as blood pressure, pulse, and weight, but are these measurements really showing the full picture of a person's overall health? Extensive research shows health care professionals should be considering something often overlooked - muscle mass.
Scientists have discovered a neural mechanism for making rapid, fine adjustments in precise motor activity. The brain's premotor cortex may use a 'neural scratch pad' between it and the primary motor cortex to calculate fine adjustments in reaching plans.
In a survey-based study of 21,889 adults in Canada, severe and/or frequent physical abuse during childhood and frequent childhood exposure to intimate partner violence were linked with higher risks or arthritis during adulthood arthritis, even after controlling for a range of factors.
Researchers from Beijing have developed a new technique of external ventricular drain (EVD) insertion that involves the use of a mixed-reality holographic computer headset. Wearing this headset, the neurosurgeon can visualize holographic images of individual patients' brain structures while performing the procedure. This makes EVD insertion more accurate than the usual freehand technique, which relies only on referral to external anatomical landmarks.
Intravenous, low-dose ketamine (LDK) is as effective as intravenous morphine in the control of acute pain in adults in the emergency department (ED).
US states with high levels of household gun ownership have higher rates of fatal shootings of civilians by police than states with lower gun prevalence, according to a new study led by researchers from the Harvard T.H. Chan School of Public Health and Northeastern University.
University of Utah biomedical engineering assistant professor Robby Bowles and his team have developed a method to 3D print cells to produce human tissue such as ligaments and tendons to greatly improve a patient's recovery. A person with a badly damaged ligament, tendon, or ruptured disc could simply have new replacement tissue printed and ultimately implanted in the damaged area.
In a study of four patients with a rare genetic disorder, NIH researchers found that the PIEZO2 gene may be responsible for tactile allodynia: the skin's reaction to injury that makes normally gentle touches feel painful. This and a second NIH-funded study showed how the gene may play an essential role in the nervous system's reaction to injury and inflammation, making PIEZO2 a target for developing precise treatments for relieving the pain caused by cuts, burns, and other skin injuries.
A research team at the Krembil Research Institute in Toronto has developed an innovative strategy that could help to restore breathing following traumatic spinal cord injury.
