Multimodal Optical Diagnostics of the Microhaemodynamics in Upper and Lower Limbs
Conclusion The use of optical non-invasive diagnostic methods has a great potential for the detection of concomitant microcirculation disorders in patients with rheumatic diseases and diabetes. In this review, it was shown that the use of laser Doppler flowmetry, optical tissue oximetry and fluorescence spectroscopy together or separately may have important diagnostic value for the detection of violations, assessment of their severity, as well as for the analysis of the effectiveness of the therapy. The joint application of the considered technologies with the methods of machine learning (discriminant analysis) can be use...

Osteoporosis and Sarcopenia Increase Frailty Syndrome in the Elderly
Conclusions World population is aging and the increase in life expectancy is often unhealthy. In particular, musculoskeletal aging, which leads to sarcopenia and osteoporosis, has several causes such as changes in body composition, inflammation, and hormonal imbalance. Sarcopenia, osteoporosis, and more frequently, sarcopenic obesity are commonly associated with aging and frequently closely linked each other, often leading to the development of a frailty syndrome. Frailty syndrome favors an increased risk of loss function in daily activities, for cardiovascular diseases, cancers, falls, and mortality. As the number of eld...

Beta Amyloid Deposition Is Not Associated With Cognitive Impairment in Parkinson's Disease
In this study, we used a well-validated visual assessment to clinically rate scans as being amyloid positive or negative (38). As there is not an accepted threshold based on standardized centiloid reference regions, we defined an amyloid positivity centiloid cut-off threshold in our sample. Our cut-off (CL = 31.3, SUVR = 1.21) corresponds well to the estimated value proposed by Rowe and colleagues (34) in the context of AD (CL = 25–30), however our estimated threshold may be biased by the low number of Aβ positive patients. Our results suggest a lower prevalence of amyloid-positive PDD individuals than in ...

The Predictive Capacity of the Buffalo Concussion Treadmill Test After Sport-Related Concussion in Adolescents
Conclusion This study found that the ΔHR (HRt minus resting HR) correlated with duration of clinical recovery in participants who were prescribed relative rest or a placebo-stretching program but not for participants prescribed sub-threshold aerobic exercise. A ΔHR of ≤50 bpm on the BCTT was 73% sensitive and 78% specific for predicting delayed recovery in concussed adolescents prescribed the current standard of care (i.e., cognitive and physical rest). This has implications for planning team and school activities in adolescents who sustain SRC. Ethics Statement This study was carried out in acco...

Modulating Applied Task Performance via Transcranial Electrical Stimulation
Conclusion tES may prove valuable for modulating applied task performance, though research in this area warrants careful consideration of several individual-, context-, and task-related factors that may predict the robustness and directionality of tES effects. Whereas most applied research with tES has administered tDCS, tACS and tRNS have also shown potential to modulate cortical activity and behavior. Even in highly applied and dynamic tasks, such as navigation and driving, tES appears to carry some performance benefits. This is compelling because as tES is slowly incorporated into highly complex real-world environments...

Scientists Identify New Type of Brain Degeneration That Mimics Alzheimer ’s. Here’s What to Know
(WASHINGTON) — Some people told they have Alzheimer’s may instead have a newly identified mimic of the disease — and scientists say even though neither is yet curable, it’s critical to get better at telling different kinds of dementia apart. Too often, the word dementia is used interchangeably with Alzheimer’s when there are multiple types of brain degeneration that can harm people’s memory and thinking skills. “Not everything that looks like Alzheimer’s disease is Alzheimer’s disease,” said Dr. Julie Schneider, a neuropathologist at Rush University Medical Center...

Sex Difference of Radiation Response in Occupational and Accidental Exposure
Conclusion and Outlook This review summarizes the data from major human studies on the health risks of radiation exposure and shows that sex can potentially influence the prolonged response to radiation exposure (Figure 1 and Tables 1, 2). These data suggest that long-term radiosensitivity in females is higher than that in males who receive a comparable dose of radiation. Our analysis of the literature agrees with the conclusions of the recent report on the Biological effects of ionizing radiation (BEIR VII) published in 2006 by the National Academy of Sciences (NAS), United States (National Research Council, 2006). The B...

What ’s the Big Deal about Data in Medtech?
Discussion, “Top 5 Things You Need to Know about the Implantable Internet of Things." Brian Chapman, partner and leader of ZS’s medtech practice of ZS, attributes today’s focus on data to the intersection of two important things: "A general recognition that understanding more and connecting actions with outcomes will provide feedback and understanding that will drive standards of care. This is not new, but as capabilities rise in data collection, aggregation, and synthesize rise, and coupled with machine learning, the promise of data in healthcare is becoming even more ...

Consider the Promises and Challenges of Medical Image Analyses Using Machine Learning
Medical imaging saves millions of lives each year, helping doctors detect and diagnose a wide range of diseases, from cancer and appendicitis to stroke and heart disease. Because non-invasive early disease detection saves so many lives, scientific investment continues to increase. Artifical intelligence (AI) has the potential to revolutionize the medical imaging industry by sifting through mountains of scans quickly and offering providers and patients with life-changing insights into a variety of diseases, injuries, and conditions that may be hard to detect without the supplemental technology. Images are the largest source...

Finding the everyday miracles in life
Last week I was writing about what it takes for a miracle to happen and one of my commentators, the lovely Patsy Collins who joined me on the podcast not that long ago, pointed out that there are all sorts of miracles that happen, including some everyday miracles we never know about, because they happen behind the scenes. And it got me thinking about the all the little miracles that have happened in my life over the years. And, once I got thinking, I got into musing about what life would be like if they hadn’t happened. And, as it’s been a week of ups and downs on the exam front I thought I might as well start ...

Will MRI replace the EEG for the diagnosis of nonconvulsive status epilepticus, especially focal?
Authors: Gelisse P, Genton P, Crespel A, Lefevre PH Abstract Magnetic resonance imaging (MRI) can now be used to diagnose or to provide confirmation of focal nonconvulsive status epilepticus (NCSE). Approximately half of patients with status epilepticus (SE) have signal changes. MRI can also aid in the differential diagnosis with generalized NCSE when there is a clinical or EEG doubt, e.g. with metabolic/toxic encephalopathies or Creutzfeldt-Jakob disease. With the development of stroke centers, MRI is available 24h/24 in most hospitals. MRI has a higher spatial resolution than electroencephalography (EEG). MRI wit...
