Research led by Carnegie Mellon University has developed a model that can accurately predict how stay-at-home orders like those put in place during the COVID-19 pandemic affect the mental health of people with chronic neurological disorders such as multiple sclerosis.

Researchers from CMU, the University of Pittsburgh and the University of Washington gathered data from the smartphones and fitness trackers of people with MS both before and during the early wave of the pandemic. Specifically, they used the passively collected sensor data to build machine learning models to predict depression, fatigue, poor sleep quality and worsening MS symptoms during the unprecedented stay-at-home period.

Before the pandemic began, the original research question was whether digital data from the smartphones and fitness trackers of people with MS could predict clinical outcomes. By March 2020, as study participants were required to stay at home, their daily behavior patterns were significantly altered. The research team realized the data being collected could inform the effect of the stay-at-home orders on people with MS.

"It presented us with an exciting opportunity," said Mayank Goel, head of the Smart Sensing for Humans (SMASH) Lab at CMU. "If we look at the data points before and during the stay-at-home period, can we identify factors that signal changes in the health of people with MS?"

The team gathered data passively over three to six months, collecting information such as the number of calls on the participants' smartphones and the duration of those calls; the number of missed calls; and the participants' location and screen activity data. The team also collected heart rate, sleep information and step count data from their fitness trackers. The research, "Predicting Multiple Sclerosis Outcomes During the COVID-19 Stay-at-Home Period: Observational Study Using Passively Sensed Behaviors and Digital Phenotyping," was recently published in the Journal of Medical Internet Research Mental Health. Goel, an associate professor in the School of Computer Science's Software and Societal Systems Department (S3D) and Human-Computer Interaction Institute (HCII), collaborated with Prerna Chikersal, a Ph.D. student in the HCII; Dr. Zongqi Xia, an associate professor of Neurology and director of the Translational and Computational Neuroimmunology Research Program at the University of Pittsburgh; and Anind Dey, a professor and dean of the University of Washington's Information School.

The work was based on previous studies from Goel's and Dey's research groups. In 2020, a CMU team published research that presented a machine learning model that could identify depression in college students at the end of the semester using smartphone and fitness tracker data. Participants in the earlier study, specifically 138 first-year CMU students, were relatively similar to each other when compared to the larger population beyond the university. The researchers set out to test whether their modeling approach could accurately predict clinically relevant health outcomes in a real-world patient population with greater demographic and clinical diversity, leading them to collaborate with Xia's MS research program.

People with MS can experience several chronic comorbidities, which gave the team a chance to test if their model could predict adverse health outcomes such as severe fatigue, poor sleep quality and worsening of MS symptoms in addition to depression. Building on this study, the team hopes to advance precision medicine for people with MS by improving early detection of disease progression and implementing targeted interventions based on digital phenotyping.

The work could also help inform policymakers tasked with issuing future stay-at-home orders or other similar responses during pandemics or natural disasters. When the original COVID-19 stay-at-home orders were issued, there were early concerns about its economic impacts but only a belated appreciation for the toll on peoples' mental and physical health -- particularly among vulnerable populations such as those with chronic neurological conditions.

"We were able to capture the change in people's behaviors and accurately predict clinical outcomes when they are forced to stay at home for prolonged periods," Goel said. "Now that we have a working model, we could evaluate who is at risk for worsening mental health or physical health, inform clinical triage decisions, or shape future public health policies."

Killexams : Why are you hoarding your old smartphones? No result found, try new keyword!The world’s biggest smartphone maker, Apple, does seem to be connecting the dots on its responsibility here. The company uses recycled materials across its products and has invested in systems ... Sat, 15 Oct 2022 06:28:00 -0500 en text/html Killexams : App turns smartphones into electronic stethoscopes

Smartphones are beginning to have a real influence on the way we manage our day-to-day health, and one area they may have a significant impact is in monitoring our hearts. A new study has demonstrated that an app designed to turn smartphones into electronic stethoscopes can capture reliable, quality recordings of user heartbeats across the population, which doctors can then use to remotely monitor progression of heart conditions.

The Echoes app is designed to perform the role of a traditional stethoscope. Users simply place the phone’s microphone directly on their skin in a quiet environment, with an onscreen slider enabling them to tune the microphone’s sensitivity to ensure they capture their beating heart.

The app was launched last May and has since gathered more than 100,000 heart recordings. These are added to a database for scientists at Kings College London and the Maastricht University in the Netherlands to analyze for sound quality and try to spot clinical markers of cardiac events.

In newly published research, the scientists assessed more than 7,500 recordings, along with data on users’ gender, age, body mass index (BMI) and phone hardware. While the team found that success rate of good recordings tended to decrease with user age, their gender, BMI or phone hardware did not alter the quality of the recordings.

"This research proves that mobile technologies are a viable way of recording heart sounds and that in the future, cardiac patients and doctors could use at-home recordings to check for existence or progression of heart conditions,” said lead researcher, Professor Pablo Lamata.

As a sign of how things are developing in smartphone diagnostics and heart health, in 2015 we looked at a related technology that performed as well as traditional stethoscopes. But rather than using the phone’s onboard microphone, the technology relied on an additional recording device that was placed against the patient’s skin and wired into an iPhone’s headphone jack.

In having the entire phone do the legwork on its own, the Echoes app could bring this functionality to everyday users. The team says more work is needed to explore how the app can work with existing heart monitoring solutions, but are excited about the possibilities.

"Our study has answered the central question to large-scale applications of using a smartphone microphone as a stethoscope,” said study author Hongxing Luo, from Maastricht University. “The results have shown that non-medical users are able to record heart sounds in sufficiently good quality for further processing of the signals. We may be able to extract further features for diagnosis and monitoring purposes in future clinical studies."

The research was published in the European Heart Journal - Digital Health.

Killexams : Signs of smartphone addiction in children Living in a world surrounded by digital devices is surely a boon. However, it can take a baneful turn, when the same gadgets become a compulsion.
Smartphone addiction has become extremely common not just among adults but even kids.
About 23.80% of children are said to use smartphones while they are in bed, before going to sleep and 37.15% of children, always or frequently, experience reduced levels of concentration due to smartphone usage, as per a study conducted by National Commission for Protection of Child Rights.
Another study published in 2019 evaluated 41 studies published between 2011 and 2017 and suggested that 23% of children have “problematic smartphone usage” that leads to negative mental health effects.

Therefore, these alarming data highlight the need to address the problem and to help children productively use their smartphones.

The risk of smartphone addiction

As discussed, spending too much time on the smartphone can have an adverse effect on children's physical and mental health. From behavioural problems, sleep disturbances, depression, to obesity, nervous system problems and slower social development skills, there could be many side effects of excessive phone usage.

Another problem that could arise is a compulsive behaviour, which refers to an urge to perform an action persistently and repetitively. In this case it could mean wanting to check the phone again and again, inability to break away, always being thinking about losing battery or forgetting a charger, etc.. When these factors start affecting a child's daily life, that's when their smartphone usage becomes concerning.

Warning signs to note

The best place to start is to identify the signs of smartphone addiction. To help do that, here are some warning signs to watch out for in kids:

- Insomnia or difficulty in sleeping

- Anxiety or constant worry around his phone

- Anger and aggression
- Compulsion

- Self-isolation and distancing oneself from loved ones

- Distress when the child cannot find his/her phone

How to help children break away from overreliance on smartphones

While breaking away a child's addiction to smartphones can be challenging and overwhelming at the same time, it is not impossible, especially if you find creative ways to do that.

- Make family time necessary - do not allow screens during this time

- A strict smartphone schedule is key

- Avoid letting them use their phones at bedtime.

- Fix a screen time limit

- Do not use smartphones as reward or distraction

- Identify their interests and play into it
- Do not lecture them on smartphone use rather lay down the pros and cons
Set good examples
As a parent, you should also make sure that you do not set wrong examples. Adults are as capable as kids to get addicted to phones. So when you're in front of your children, avoid using your phones and spend more quality time with them.

Killexams : A Lenovo ThinkPad smartphone could be on the way


  • Lenovo could be working on a ThinkPad smartphone.
  • The so-called ThinkPhone might be rebranded Motorola device, though.

Lenovo’s ThinkPad series of laptops have been around for years now, but it looks like the company might soon leverage the brand for its smartphone business.

Veteran tipster Evan Blass posted a low-resolution render on 91mobiles showing a smartphone with what seems to be a ThinkPhone badge on its back. You can view this image below.

Blass also notes that the supposed ThinkPhone shares the same model number (XT-2309) as an upcoming 2023 Motorola handset dubbed Bronco. This suggests that the ThinkPhone will be a rebranded Motorola device rather than an all-new phone.

Bronco is tipped to be an Edge series handset that could arrive with a Snapdragon 8 Plus Gen 1 or Snapdragon 8 Gen 2 chipset and a triple rear camera system (50MP main, 13MP ultrawide, 2MP depth).

It’s unclear if a ThinkPad smartphone will actually see the light of day, but we hope Lenovo brings a few more additions if it’s a rebranded offering. Motorola and Lenovo already have a feature-filled desktop mode on Android, so a ThinkPad wireless keyboard (complete with the signature mouse nub) seems like a sensible starting point.

Would you buy a ThinkPad smartphone?

Killexams : Parental Tech Support: Everything you should fix on a senior’s phone


Adult children who do family tech support know the drill. Your parents call about a problem with their smartphone, maybe spam texts or something wrong with Facebook. You try to talk them through fixing it remotely with mixed results and mutual frustration.

Next time you see your parents in person (and really, you should visit more often) do everyone a favor. Take 30 minutes to borrow their phone and clean house. A little maintenance now can prevent future problems with security, scams, confusion or misinformation. You are going to clear out old junk, fix any small problems and customize it so everything is a little easier for them to see and understand.

This is advice for adult children whose parents or other older relatives use a smartphone, but anyone can attempt these maintenance tasks on their own devices.

Update everything

“The first thing I do is check for what I call check engine lights,” says Abbie Richie, the founder and CEO of tech-support company Senior Savvy. “I look for red notification badges, especially in the Settings app.”

Apple and Google release regular small updates and annual big updates to their smartphone operating systems, iOS and Android. Don’t avoid them, even if you’re thinking about adding confusing new features. They often include key security patches and bug fixes. If you do a major operating system update, set aside time to walk them through the new look and options.

Set the phone to run software updates automatically in the future.

Delete and reorganize apps

Go through page by page and ask your parent what they use and what they don’t use — you’ll be surprised how many of us have apps installed we don’t remember. Delete anything that looks suspect, scammy or confusing.

Move the apps they use most to the first screen on their device. Richie recommends putting their four most used apps in the dock at the bottom of the screen and putting any other biggies in the top left or right corner. Move any apps they don’t use often but that are useful to have into clearly labeled folders, then store those folders on the last page of the home screen.

Ask them if there’s anything they want to do on their phone but can’t, like online banking. Install new apps if they need them, but keep it simple and walk them through setting up anything that needs a log-in. Write down any new passwords!

Make the screen easier to see

Our eyesight deteriorates as we age and even the largest phone can be tricky to read. Smartphones are packed with accessibility settings that you can dive into, but to start let’s just make everything a little bigger and brighter.

In Settings, bump up the text size and make it bold. You can turn on a setting like iOS’s Display Zoom, which makes everything a bit larger across the board. Finally, turn the brightness all the way up and show them how to control it themselves. Experiment with toggling between light and dark modes and see if one is easier for them to see.

Richie also suggests giving your parents more time before their phones lock. Instead of 30 seconds or one minute, bump the auto-lock up between 3 and 5 minutes.

Turn on emergency and health settings

Add any medical conditions and allergies to the phone’s built-in emergency settings. On an iPhone, go to Medical ID in the Health settings. On an Android device, you can go to the Safety & Emergency settings. Add emergency contacts, including people who live close as well as immediate relatives. Make it so this information can be viewed in an emergency, even if the phone is locked.

Many smartphones have health monitoring options built in. On the iPhone for example, you can turn on notification for walking steadiness, which might come in handy to avoid future falls. If they want you or someone else to be more involved with their health, you can set up sharing for health information.

Cut down on misinformation

If you’re thinking about your parents falling for disinformation or being radicalized online, you can make a few minor changes to make things better. Pick a reputable news outlet or app and move it to a prominent place on their home screen. Apple News and Google News both do a decent job of including a wide range of trustworthy news sites. Put a shortcut to a fact-checking site like Snopes on their home screen so they can quickly gut check any stories or social media posts they come across. Walk through their social media accounts with them, if they’ll let you. Ask if you can unfollow any pages or influencers who traffic in disinformation or propaganda.

Minimize scamming attempts

Seniors are a popular target for scammers. You can tweak a few settings to cut down on attempts. We walk you through all of them here, but start with sending unknown calls directly to voice mail (Settings → Phone → Silence Unknown Callers on an iPhone), filtering texts from unknown senders and turning on any spam filters or detection offered by their phone or cell carrier.

Go through their friend lists on Facebook and Instagram and weed out any fake seeming accounts, including people they don’t know and accounts imitating other people. You can find more settings to change on their smartphone and messaging apps here.

Check their subscriptions

Make sure they’re not paying for anything by accident, like an app they subscribed to or a scammy “tech support” service. Go through their Android or iOS subscriptions first, then ask if they want to review their accurate bank account statement.

Set up cloud backups

Turn on automated backups, especially for photos. If they have a full phone, you can set it to delete photos or videos from the device to clear up space. If their device is ever lost, stolen or broken, they’ll still have all their data and memories ready to go. You can find more storage instructions for Google Drive here and Apple’s iCloud here.

Introduce them to Siri

Navigating around a smartphone screen can be more difficult as people lose dexterity and their eyesight worsens. Android and iPhones have a great built-in shortcuts that can help seniors: voice assistants. Walk them through how to activate Siri or Google Assistant, writing down a list of starter commands for them to get used to, like dictating a text.

Let your parents show you what they need

“I always ask my clients, ‘show me what you mean,’ ” says Richie. Something that may be hard to explain to you over the phone could be clearer by having them walk you through the process. For example, Richie had one client who struggled to send text messages. It turned out they were holding a finger on the send arrow too long, accidentally bringing up the special effects option in Messages.

Use parental controls

If your parent is dealing with any type of cognitive decline, you can discuss using stronger controls on their devices so you can access or block things remotely. You can also ask them to share log-ins and passwords, or store them somewhere easy to access. This should be done with their consent and full understanding of what you’ll be able to access.

Keep checking in

Write down everything new you’re telling your parents so they have something to reference. If you live too far away to deliver constant tech support, find a trusted local computer shop that does house calls or deputize another tech savvy relative. Richie says to be ready for more phone calls and questions, and that’s okay.

“Be completely prepared that they may need you to show them how to do this again and again and again, with love.”

Killexams : The Best Smartphones Of 2022 Ranked

OnePlus started as a scrappy underdog, with giant-killer, invite-only smartphones that promised flagship performance for a mid-range price. Now they've become a significant competitor in several regions around the world, beating Google in U.S. smartphone sales in 2021.

Last year, they merged with OPPO, another Chinese smartphone manufacturer, and fans thinking that the OnePlus spark would get snuffed out. A year later, all that seems to have happened is that OnePlus has access to OPPO's supply chain and the ability to scale.

The OnePlus 10 Pro 5G is the "most advanced smartphone the brand has released thus far." It's a flagship with every high-end feature you could want, and while the $799 base purchase price is significant, it's cheaper than comparable devices from Samsung or Apple.

This device's camera cluster was developed in partnership with Hasselblad, part of a $150 million investment from OnePlus that will end in 2024. On the OnePlus 10 Pro 5G, the Hasselblad branding is prominently displayed on the camera cluster and inside the camera app as a Hasselblad-branded "Pro" mode which lets you manually control things like ISO, shutter, EV, focus, and white balance.

That app controls a 48-megapixel primary lens, a 50-megapixel ultra-wide, and an 8-megapixel telephoto. You can record 8K video at 24fps, 4K at 30/60/120fps, or super slow motion with 1080p at 240fps or 720p at 480fps.

The icing on the cake here is that the OnePlus 10 Pro 5G has 5G compatibility with each of the three major mobile data carriers in the United States: Verizon, AT&T, and T-Mobile.
