Tiny lensless endoscope captures 3D images of objects smaller than a cell: Self-calibrating technology opens new opportunities for medicine and research

Researchers have developed a new self-calibrating endoscope that produces 3D images of objects smaller than a single cell. Without a lens or any optical, electrical or mechanical components, the tip of the endoscope measures just 200 microns across, about the width of a few human hairs twisted together. As a minimally invasive tool for imaging features inside living tissues, the […]

Blood pressure recording over 24 hours is the best predictor of heart and vascular disease

High blood pressure is the most important treatable risk factor for diseases of the heart and the arterial system. Blood pressure recorded over 24 hours predicts these complications more accurately than blood pressure measured on a single occasion. That is the conclusion of an international study coordinated by Professors Jan A. Staessen and Zhen-Yu Zhang of KU Leuven in Belgium. […]

Dizziness of unknown cause may be perception disorder: Perception disorders may throw those affected off balance

Many patients with functional dizziness look back on a long odyssey to numerous doctors, because no organic causes could be found. Now for the first time, an experiment at the Technical University of Munich (TUM) has identified possible causes of the disorder: problems with the processing of sensory-motor signals in the brain that resemble those associated with dizziness due to […]

Improving outcomes for sepsis patients

More than 1 million sepsis survivors are discharged annually from acute care hospitals in the United States. Although the majority of these patients receive post-acute care (PAC) services, with over a third coming to home health care (HHC), sepsis survivors account for a majority of readmissions nationwide. Effective interventions are needed to decrease these poor outcomes. A national study from […]

Body and mind need care in mental illness

The 18-year life expectancy gap between people with mental illness and the general population can only be bridged by protecting patients’ physical and mental health, according to a new study. As part of a Lancet Psychiatry Commission into mental illness, University of Queensland researchers found patients’ physical health was often overlooked in pursuit of treating the mind. UQ psychiatrist Associate […]

Ultrasound-assisted optical imaging to replace endoscopy in breakthrough discovery

Carnegie Mellon University’s Assistant Professor of Electrical and Computer Engineering (ECE) Maysam Chamanzar and ECE Ph.D. student Matteo Giuseppe Scopelliti today published research that introduces a novel technique which uses ultrasound to noninvasively take optical images through a turbid medium such as biological tissue to image body’s organs. This new method has the potential to eliminate the need for invasive […]

Prescribed opioids associated with overdose risk for family members without prescriptions: Case control study finds nearly threefold increase in overdose rates for those on same health insurance plan as person with opioid prescription

According to the Centers for Disease Control and Prevention, opioid overdoses were responsible for more than 42,000 deaths in 2016. Access to family members’ drugs may be a strong risk factor for overdose in individuals without their own prescriptions, according to a new study by investigators from Brigham and Women’s Hospital. Their findings were published recently in JAMA Internal Medicine. […]

Athletes at a higher risk for ACL injury after return to sport

Young athletes who do not achieve a 90 percent score on a battery of tests that measure fitness to return to athletic competition, including quadricep strength, are at increased risk for a second knee injury, according to research presented at the Annual Meeting of the American Orthopedic Society of Sports Medicine. Orthopedic surgeons and sports medicine professionals have established return-to-sports […]

Dentistry: Root canal work not so bad after all

Root canal work is not as bad as people think when compared to other dental procedures. Self-reporting of their dental health suggests that patients find the procedure no worse than other dental work which overturns the popular belief that root canal work is the most unpleasant dental treatment. Dr Tallan Chew, postgraduate student, Adelaide Dental School, University of Adelaide co-authored […]

Blood flow monitor could save lives: Fibre-optic probe gives continuous cardiac measure

A tiny fibre-optic sensor has the potential to save lives in open heart surgery, and even during surgery on pre-term babies. The new micro-medical device could surpass traditional methods used to monitor blood flow through the aorta during prolonged and often dangerous intensive care and surgical procedures — even in the tiniest of patients. The continuous cardiac flow monitoring probe, […]
