@mishtu To classify the sounds, the computer-assisted stethoscope uses a separation algorithm that physically and mathematically divides them into each of the five groups according to the duration, frequency, and strength of the sound
@jhilmil The thinking behind mobile heart-rhythm monitoring is simple: Stroke is a major health problem. AF associates with stroke. We have a treatment for stroke reduction (anticoagulants). Thus, it would be great to screen more people to detect AF. The problem is that simple thinking rarely works in medicine—an observation that was made long before mobile tech.
@anuraag Average blood pressure reading is the only measurement on which a doctor can accurately diagnose and treat high blood pressure, she says. A new study by Green and other researchers at Kaiser Permanente shows that giving patients the chance to monitor their blood pressure at home could help get more reliable measurements. Nearly one in four adults in the U.S. with high blood pressure are unaware they have the condition and are not getting treatment to control it. Without treatment, the condition can cause heart attacks, strokes, kidney damage, and other potentially life-threatening health problems. Current guidelines for diagnosing high blood pressure recommend that patients whose pressure is high in the clinic get tested again to confirm the results. While the guidelines recommend home monitoring before diagnosing high blood pressure, research shows that doctors continue to measure blood pressure in their clinics for the second reading.
@ashmita At-home blood pressure monitors have been around for many years now. They work just like the blood pressure machines doctors use at their office: You place your arm inside a cuff, press a button, feel a squeeze on your arm, and get a reading. While results from this method are accurate, they are also just a moment in time. Our blood pressure can vary greatly throughout the day — especially among people who have labile hypertension, where blood pressure changes from one extreme to the other. So, looking at point-in-time readings is a bit like focusing on a few dots inside of a pointillism painting — one might miss the bigger picture.
@antara The entire DLS approach does not involve any objective judgment and the feature extraction process is entirely automatic. Numerous unconventional features…are assessed. Thus, DLS can help clinicians detect subtle changes, patterns, and abnormalities that may be overlooked or disregarded by humans
@premlata The study was conducted at two hospitals in China among consecutive patients prepping for colonoscopy. All participants received standard bowel preparation instructions and were given a leaflet with general guidelines on bowel preparation. The leaflet included photos representing bowel preparation quality and informed patients that their stool should eventually be a yellowish clear liquid; if any cloudiness (including turbid liquid, particles, or small amounts of feces) is observed in the liquid stool, the bowel preparation is not complete. All patients were prescribed standard polyethylene glycol electrolyte solution for bowel cleansing 4 to 6 hours before the colonoscopy.
@vinit It's not yet quite to the point where we could see somebody print out a functioning heart. That's too complicated in terms of getting everything right so that it would work — although someday, but not soon. Same thing with a functional liver. Think about blood components, skin, or maybe the lining of the intestine. There are areas where bioprinting, I think, holds much in store for the future of repair of damaged organs or birth defects. That's very exciting. I don't have much ethical objection about those uses. They sound wonderful. Things that we didn't know how to repair or couldn't do very well cosmetically, now we're seeing the bioprinter suddenly jump in and start to be used to manufacture body parts.
@prachi In other words, digital therapeutics complement what happens in physical and occupational therapy sessions with scientifically-informed behavioral interventions based on technology and software
@maggie The device is intended for use as part of a therapeutic program that may include clinician-directed therapy, medication, and/or educational programs, which further address symptoms of the disorder
@will The study included 47 college students. Of these, 28 reported playing action video games for at least 5 hours per week over the previous 2 years, while the remaining "non-gamers" averaged less than 1 hour per week of play. During functional MRI, participants were given a left-right moving dots task in which they were asked to press a button in their right or left hand to indicate the direction dots were moving — or resist pressing either button if there was no directional movement.
@angana Cancer is caused by DNA mutations, or, more simply put, "mistakes." Some are tiny – like when just one letter of genomic code is off. These are "relatively easy to interpret," Pillay says. But copy number changes are bigger. If your DNA is a book, copy number changes mean whole words, sentences, or entire pages can be wrong.
@aparupa A substantial percentage of patients who have esophageal reflux symptoms do not have gastroesophageal reflux disease (GERD) and can stop taking PPIs. Wireless reflux monitoring performed while patients are not taking PPIs is the gold standard for determining whether a patient has abnormal acid from GERD, but the optimal daily acid exposure time (AET) and the optimal duration of monitoring have not been well studied. Aiming to fill this knowledge gap, Yadlapati and her colleagues conducted a single-arm, double-blinded clinical trial over 4 years at two tertiary care centers. They enrolled adult patients who had demonstrated an inadequate response to more than 8 weeks' treatment with PPIs.
@aparupa In a separate study of around 1.5 million children in England, they found the algorithm could identify type 1 diabetes in 75% of affected children 11 days earlier than without the tool, if it was set up as an alert at every one in 10 general practice consultations.
@aditya Cognitive deficits affecting a range of functions — including memory, attention and communication — are common in MS and affect 34% to 65% of patients with the disease, and the ability to detect and monitor such deficits has important implications. Cognitive changes can provide a unique opportunity to identify acute disease activity in patients with MS that might be already occurring before physical manifestations become apparent.
@paxy Hello, Children's smart watches can run applications and play various digital media, such as audio tracks or broadcasts to Bluetooth headsets. Many of these watches have touch screens that allow you to use functions such as calculators, thermometers, and compasses. Currently, most of the iterations of Umeox best smartwatches are not completely independent devices, simply because they lack Internet connectivity. Therefore, many watches are designed to directly link with other Internet-connected devices. It has both its cons and pros. Even when they are not beeping, they are a distraction for children. Smart watches are by their nature delicate and can easily be damaged. Smartwatches are not durable enough to withstand the rough and tumble days of childhood. s your concern about emitting harmful rays according to scientific research has not linked these devices with health problems. These devices emit low levels of radiofrequency energy (RF), not enough to cause cell damage. Thanks!
@mansoor A MyProstateScore of 15 or below had a 100% negative predictive value and sensitivity for GG ≥ 2 cancer and would have prevented 23% of unnecessary biopsies. A score above 40 had a 19% risk of GG ≥ 2 disease. A score of 15 to 40 had a 6.5% risk of GG ≥ 2 disease. Together, the data suggest that men with a MyProstateScore of 15 or below can "confidently forego biopsy," that most men with scores of 15-40 "are unlikely to benefit from repeat biopsy," and a score greater than 40 "supports proceeding to repeat biopsy."
@bipasha In 98% of cases, the MRI-based machine learning tool alone could accurately predict whether an individual had AD, outperforming standard hippocampal volume and cerebrospinal fluid (CSF) amyloid-beta measurements. It could also distinguish between early- and late-stage AD in 79% of patients. The tool was "robust and repeatable across MRI scans, demonstrating its potential for applicability in clinical practice in the future," the researchers write.
@paromita AID systems are not approved by any regulatory body, and despite several nonrandomized studies demonstrating their effectiveness and safety, there is still concern among some health professionals about their safety. In 2019, the US Food and Drug Administration (FDA) warned against the use of any nonapproved devices or algorithms. (Now, though, at least one open-source AID system algorithm is under FDA review.) Aimed at addressing those concerns, CREATE (Community Derived Automated Insulin Delivery) is the first randomized controlled clinical trial to compare an open-source AID system to insulin pump therapy and CGM (without any communication between the two) in patients with type 1 diabetes, most of whom were naive to AID systems.
@vikrant The "Foot Selfie System" eliminates the need for assistance and allows the images to be sent to a clinician. The point of it is to be a very simple tool that essentially anybody can use. Clearly there could be an artificial intelligence filter and patients could be taught to not rely on someone looking but rather to report a concern [and] a human would [then] look at the pictures
@shreemoyee During the initial interviews, 69.9% of patients complained of having attentional issues, 58.9% complained of having memory problems, and 55.7% of patients complained of both. In assessing fatigue and depression, with the Brief Fatigue Inventory and the Patient Health Questionnaire-9, respectively, the patients had significantly worse scores for both than the controls (P < .0001 for both).
