Tips for doing DIY predictive analytics right

Michael Johnson, a decision support data scientist at Bend, Oregon-based St. Charles Health System, has only worked in healthcare for a couple years. Before that, he'd spent most of his career doing data modeling and predictive analytics in higher education and in the military. During his short time so far in this data-intensive industry, Johnson,

Double-bridged peptides bind any disease target

Peptides are short chains of amino acids that can bind to proteins and change their function. They show high binding affinity, low toxicity, and are easy to synthesize, all of which makes peptides ideal for use in drug development, and many naturally occurring peptides such as insulin, oxytocin, somatostatin and the antibiotics vancomycin or polymyxin

Shocking difference between healthy lungs and those of a smoker

Watch what cigarettes really do to the lungs: Shocking video shows the difference between healthy organs and those of a pack-a-day smoker WARNING: GRAPHIC CONTENT  Videos show the black, cancer-ridden lungs of a heavy smoker, failing to inflate This is compared to the healthy, red-coloured lungs of a non-smoker The non-smokers’ lungs filled to full

Calcium-based MRI sensor enables more sensitive brain imaging: System detects direct signals of neural activity; could reveal patterns underlying behavior

MIT neuroscientists have developed a new magnetic resonance imaging (MRI) sensor that allows them to monitor neural activity deep within the brain by tracking calcium ions. Because calcium ions are directly linked to neuronal firing — unlike the changes in blood flow detected by other types of MRI, which provide an indirect signal — this

Using mathematical modeling and evolutionary principles important in treatment decisions: Moffitt researchers show continuous maximum dose and adaptive treatment approaches are effective strategies for different tumors

Cancer patients are commonly treated with the maximum dose they are able to withstand that does not cause too many toxic side effects. However, many patients become resistant to these treatments and develop cancer recurrence. Researchers at Moffitt Cancer Center are using mathematical modeling based on evolutionary principles to show that adaptive drug treatments based

Cancer patients set to benefit from world’s largest surgery study

Improved care for patients undergoing cancer surgery is the focus of a pioneering worldwide study. Doctors say the initiative—funded by the National Institute for Health Research (NIHR) – will enable them to gauge surgery quality across the globe and highlight ways to improve patient care. Some 16 million people worldwide will be diagnosed with cancer

Survey: Medical marijuana could reduce opioid use in older adults

A questionnaire of older men and women suffering from chronic pain who were given medical marijuana found that the drug significantly reduced pain and their need for opioid painkillers, Northwell Health researchers report. The results of the study, “Older Adults’ Use of Medical Marijuana for Chronic Pain: A Multisite Community-Based Survey,” are scheduled to be

Pill for breast cancer diagnosis may outperform mammograms

As many as one in three women treated for breast cancer undergo unnecessary procedures, but a new method for diagnosing it could do a better job distinguishing between benign and aggressive tumors. Researchers at the University of Michigan are developing a pill that makes tumors light up when exposed to infrared light, and they have

3-D-printed templates aid mandibular fracture repair

(HealthDay)—A three-dimensional (3-D)-printed short-segment template prototype is feasible for management of complex mandibular fractures, according to a study published online April 26 in JAMA Facial Plastic Surgery. Parul Sinha, M.B.B.S., from the Washington University School of Medicine in St. Louis, and colleagues conducted a feasibility study using maxillofacial computed tomography data of three patients with

VIRGINIA IRONSIDE on the new partial knee replacements

‘Having BOTH knees done in the same op halved my recovery time’: Agony aunt VIRGINIA IRONSIDE on the new partial replacements that get you quickly back on your feet Virginia Ironside discusses the new partial replacements that get you quickly back on your feet What was it, six months ago, that prompted me to consult

Effects of night-time light on internal body clock

New research published in The Journal of Physiology has illuminated the effects of night-time light exposure on internal body clock processes. This is important for helping those who have poor quality sleep, such as shift workers, and could help improve treatments for depression. The body has an internal clock that causes various physiological processes to

Doctors advise on what ACTUALLY helps back pain

How to REALLY beat back pain: As new studies reveal many treatments do little to help, doctors offer advice on what actually works and what doesn’t Four out of five adults in the UK experience back pain at some point in their life It accounts for seven million trips to the GP a year, many

New carbon-dioxide-adsorbing crystals could form the basis of future biomedical materials that rely on the shape-memory effect

Kyoto University scientists are one step closer to designing porous materials that can change and retain their shapes — a function known as shape-memory effect. Shape-memory materials have applications in many fields. For example, they could be implanted in the body and then induced to change shape for a specific function, such as serving as
