The Drones of War

#artificialintelligence

North American professional drone maker Draganfly has sent the first of nearly a dozen humanitarian drones to the non-profit Ukraine organization Revived Soldiers Ukraine (RSU) in Europe, to be used to deliver insulin to hard-to-reach hospitals in the war-torn country. RSU has ordered 200 medical response drones from Draganfly, each costing $30,000 and equipped with temperature-managed payload boxes that can transport up to 35 pounds of blood, pharmaceuticals, insulin/medicines, vaccines, and wound care kits, the drone maker said. Because insulin is a temperature-sensitive product, quick and safe transportation is a top priority. There are roughly 2.3 million people living with diabetes in Ukraine, according to the International Diabetes Association, many of whom have Type 1 diabetes and require multiple daily injections of insulin to survive. For those living in high-conflict areas of the country, access to life-saving insulin is limited or non-existent.


Painless wearable gadget can measure blood sugar, alcohol and muscle fatigue at the SAME time

Daily Mail - Science & tech

A new wearable gadget that fixes to the arm can measure blood sugar and muscle fatigue at the gym and alcohol levels at the pub. Created in California, the prototype can continuously monitor three health stats – glucose, alcohol and lactate levels – either separately or simultaneously in real-time. About the size of three poker chips stacked together, it is applied to the skin painlessly through a Velcro-like patch of microscopic needles. These needles take readings from fluid under the skin and then sends the data wirelessly to a custom smartphone app. Researchers hope to commercialise the device, which could provide a single solution for diabetes patients in everyday life.


Amazon Alexa can now answer common questions around menopause

Daily Mail - Science & tech

Amazon's Alexa voice assistant is already a fount of knowledge on health topics ranging from the symptoms of chicken pox to how to relive a migraine. Now Amazon has teamed up with independent website Menopause Matters to provide answers to some of the most commonly asked questions around menopause. Alexa users in the UK can ask questions including'What treatments are available for the menopause?', 'What is perimenopause?', and'What are the benefits or risks of Hormone Replacement Therapy for menopause?' The news comes amid warnings that women going through the menopause are often mis-diagnosed with depression, because GPs do not know all the symptoms.


Estimating the informativeness of data

#artificialintelligence

Not all data are created equal. But how much information is any piece of data likely to contain? This question is central to medical testing, designing scientific experiments, and even to everyday human learning and thinking. MIT researchers have developed a new way to solve this problem, opening up new applications in medicine, scientific discovery, cognitive science, and artificial intelligence. In theory, the 1948 paper, "A Mathematical Theory of Communication," by the late MIT Professor Emeritus Claude Shannon answered this question definitively.


La veille de la cybersécurité

#artificialintelligence

Researchers from the National Institutes of Health Clinical Center developed a new artificial intelligence (AI) model that analyzed various factors relating to pancreas health and fat levels using non-contrast abdominal CT images to detect type 2 diabetes risk. The study, which was published in Radiology, evaluated 8,992 patients, of which 572 had type 2 diabetes mellitus, and 1,880 had dysglycemia. All patient screenings occurred between 2004 and 2016. To build the model researchers used 471 images obtained from various datasets. They divided the photos into three categories: 424 for training, 8 for validation, and 39 for test sets.


Machine-learning tool could aid earlier diagnosis of type 1 diabetes

#artificialintelligence

Speaking at the 2022 Diabetes UK Professional Conference, Julia Townson (Cardiff University, UK) explained that around a quarter of children with type 1 diabetes in the UK are not diagnosed until they are in diabetic ketoacidosis (DKA), with rates unchanged for 25 years despite public health campaigns, highlighting the need for improved tools for early detection. She said that previous research identified different patterns of primary care contact among children who later go on to develop type 1 diabetes versus those who do not, leading the team to hypothesize that primary care data could be used to flag those likely to be diagnosed with the condition. To investigate this, Townson and colleagues used a machine-learning algorithm drawing on 81 pieces of information from electronic health records studied from 2000 to 2016 to produce a single score that indicates the likelihood of being diagnosed with type 1 diabetes. The information used in the tool included flags such as family history, fatigue, urinary tract infections, obesity, and weight loss, as well as data on the frequency of recent primary care contact relative to average contact frequency for each child. The Welsh SAIL/Brecon registry of approximately 35 million primary care contacts for 1 million children (0.21% with type 1 diabetes) was used as the training dataset, and the tool was tested using the English Clinical Practice Research Datalink (CPRD) and Hospital Episode Statistics records involving around 43 million contacts for 1.5 million children (0.10% with type 1 diabetes).


Study finds artificial intelligence may improve diabetes diagnosis

#artificialintelligence

Bethesda (Maryland) [US], April 16 (ANI): A new study has found that a fully-automated artificial intelligence (AI) deep learning model can identify early signs of type 2 diabetes on abdominal CT scans. The findings of the study were published in the journal, 'Radiology'. Type 2 diabetes affects approximately 13 per cent of all U.S. adults and an additional 34.5 per cent of adults meet the criteria for pre-diabetes. Due to the slow onset of symptoms, it is important to diagnose the disease in its early stages. Some cases of pre-diabetes can last up to 8 years and an earlier diagnosis will allow patients to make lifestyle changes to alter the progression of the disease.


Study Finds Artificial Intelligence May Improve Diabetes Diagnosis - AI Summary

#artificialintelligence

Bethesda (Maryland) [US], April 16 (ANI): A new study has found that a fully-automated artificial intelligence (AI) deep learning model can identify early signs of type 2 diabetes on abdominal CT scans. For this retrospective study, Dr Summers and colleagues, in close collaboration with co-senior author Perry J. Pickhardt, M.D., professor of radiology at the University of Wisconsin School of Medicine & Public Health, used a dataset of patients who had undergone routine colorectal cancer screening with CT at the University of Wisconsin Hospital and Clinics. The deep learning model displayed excellent results, demonstrating virtually no difference compared to manual analysis. In addition to the various pancreatic features, the model also analyzed the visceral fat, density and volumes of the surrounding abdominal muscles and organs. The best predictor's type 2 diabetes in the final model included intrapancreatic fat percentage, pancreas fractal dimension, plaque severity between the L1-L4 vertebra level, average liver CT attenuation, and BMI.


The Strategy That Will Fix Health Care

#artificialintelligence

In health care, the days of business as usual are over. Around the world, every health care system is struggling with rising costs and uneven quality despite the hard work of well-intentioned, well-trained clinicians. Health care leaders and policy makers have tried countless incremental fixes--attacking fraud, reducing errors, enforcing practice guidelines, making patients better "consumers," implementing electronic medical records--but none have had much impact. At its core is maximizing value for patients: that is, achieving the best outcomes at the lowest cost. We must move away from a supply-driven health care system organized around what physicians do and toward a patient-centered system organized around what patients need. We must shift the focus from the volume and profitability of services provided--physician visits, hospitalizations, procedures, and tests--to the patient outcomes achieved. And we must replace today's fragmented system, in which every local provider offers a full range of services, with a system in which services for particular medical conditions are concentrated in health-delivery organizations and in the right locations to deliver high-value care. Making this transformation is not a single step but an overarching strategy. We call it the "value agenda." It will require restructuring how health care delivery is organized, measured, and reimbursed. In 2006, Michael Porter and Elizabeth Teisberg introduced the value agenda in their book Redefining Health Care. Since then, through our research and the work of thousands of health care leaders and academic researchers around the world, the tools to implement the agenda have been developed, and their deployment by providers and other organizations is rapidly spreading. The transformation to value-based health care is well under way. Some organizations are still at the stage of pilots and initiatives in individual practice areas. Other organizations, such as the Cleveland Clinic and Germany's Schön Klinik, have undertaken large-scale changes involving multiple components of the value agenda. The result has been striking improvements in outcomes and efficiency, and growth in market share. There is no longer any doubt about how to increase the value of care. The question is, which organizations will lead the way and how quickly can others follow? The challenge of becoming a value-based organization should not be underestimated, given the entrenched interests and practices of many decades. This transformation must come from within.
