Federal judge orders FDA to implement 10-month deadline for e-cig applications

A U.S. federal judge on Friday ordered the Food and Drug Administration to impose a 10-month deadline for the submission of e-cigarette applications, turning the screws on companies like Juul Labs Inc whose products have come under intense scrutiny for their popularity among teenagers.
The FDA last month proposed the shorter timeline after the U.S. District Court for Maryland ruled in a lawsuit filed by anti-tobacco groups that the agency had exceeded its authority in allowing e-cigarettes to remain on the market until 2022 before companies applied for regulatory approval.
“I will impose a ten-month deadline for submissions and a one-year deadline for approval, as the FDA suggested,” U.S. Judge Paul Grimm wrote in a court order on Friday.
Before last month, the agency had proposed makers of e-cigarettes have until August 2021 to submit a formal application to keep selling their products.

But the public health and anti-tobacco groups that originated the suit countered that e-cigarette and cigar makers submit applications within 120 days.
“Today’s ruling is an important step forward for public health and validates FDA’s commitment to accelerate review of these products, particularly the ones that are most attractive to youth,” acting FDA Commissioner Ned Sharpless said.
Juul said in a statement that it was closely assessing the court’s ruling, while adding that it was fully committed to the FDA’s application process.

AI-Powered Smart Stethoscope Revolutionizing Remote Medicine

One of the most important aspects of the routine visit to the doctor’s office is the use of the stethoscope, known as auscultation. This technique allows the physician to listen to the lungs, heart, and other organs for unusual sounds that signify various conditions. Though many apps and telemedicine platforms have allowed patients to seek medical care in the comfort of their own homes, none have been able to replicate this essential in-person procedure. By recording sound and using artificial intelligence (AI), however, the unique StethoMe device has the power to add auscultation to remote healthcare.
With a startling 80% of lung and heart sounds being misdiagnosed and improperlytreated in the WHO European region alone, StethoMe’s AI capabilities present as an attractive way to make these interpretations more consistent. In addition, the device has the potential to greatly reduce the number of unnecessary doctor visits. 70% of in-person visits are deemed unneeded and often end up exposing patients to other viruses while in the medical setting. By offering clinically supported AI in a stethoscope that can be used at home, StethoMe has the power to reduce the number of avoidable trips taken to medical centers.

What is the StethoMe Smart Stethoscope?

StethoMe is a small, wireless stethoscope that the consumer can use anywhere to conduct an auscultation. The device is paired with a smartphone app that tells the user where to properly position the stethoscope, which then collects audio from the procedure. This recording is decoded by AI that is trained to analyze respiratory and heart sounds. The processed information is sent to a physician, who then interprets the sounds as if they had the stethoscope pressed to their patient.
Using the StethoMe’s physician platform, the doctor is able to see in depth characterization from the AI, which is trained to identify wheezing and other abnormalities. In addition to the auscultation audio, StethoMe also provides the physician with a waveform of the audio. This adds a novel dimension to the examination, allowing the provider to identify visual characteristics associated with different symptoms.

On the patient’s end, they simply see a green light that indicates normal breathing sounds, or a red light that indicates abnormality. Wojciech Radomski, StethoMe’s CEO, claims this was done to leave the diagnosis in the doctor’s hands rather than having the patient falsely identify conditions.
“We only present them red or green points, which means that based on this information, they can know if there is anything wrong or not,” said Radomski in an interview with DocWire News. “We do not want users to Google their symptoms and treat themselves, we want them to connect with doctors.”

The Artificial Intelligence Behind the StethoMe

Both the device and the AI algorithm for respiratory auscultation recently received CE Certification after performing comparatively to doctors in a study published in the European Journal of Pediatrics. What enables the device to be so effective is the accurate detection of basic respiratory sounds: wheezing, rhonchi (low-pitched wheezes), and coarse and fine crackles. The AI interprets the patient’s breathing sounds and selects segments that best represent each of these four abnormalities for the physician to see.
“These four categories of sounds are the basic sounds for oral lung diseases,” noted Radomski. “Based on these sounds, doctors can diagnose different lung diseases like asthma, COPD, cystic fibrosis, and all the others. We are not focusing on any particular disease. By recognizing those basic categories of the sounds, the device can be used for any lung disease.”

Sławomir Kmak, Business Development Director at StethoMe, noted that their AI algorithm was trained using over 12,000 auscultation sounds obtained using their device. There was no pre-existing “gold standard” for such sounds, therefore their team had to gather this data on their own. After consulting with several physicians, pulmonologists, physicists, and acousticians from their partner hospitals and institutes, StethoMe was able to produce an accurate algorithm for respiratory auscultations. Kmak noted that the device can be used as a traditional stethoscope as well, with a port to plug in headphones.

Revolutionizing Remote Healthcare

After receiving many awards for their product, StethoMe now has sights set on expansion and further development of their algorithm. The AI is currently approved for observing respiratory sounds in children, but Radomski claims that adult AI will be incorporated by the end of the year.
“We started by creating the device for children — as a small company we had to focus on one target group. Currently the device [can receive sounds] from children and adults, but our AI algorithms are certified for children only. Right now, we are expanding our data base. We already have recordings of adults, but we need to gather a bit more of them to re-certify the algorithms so they will work on both children and adults.”stethome
He added that StethoMe has already developed AI that analyzes heart sounds for abnormalities as well, and that certification for this solution is to be expected by the end of the year.
Regarding commercial availability, StethoMe plans to initially launch their product in Europe but to find business partners for international expansion as well. The company also has a multi-national, multi-centered clinical study underway that is designed to once again prove the devices efficacy.
“Our dream is to put StethoMe in every home like thermometers are today,” concluded Radomski. “We want to be the best company when it comes to recognizing any abnormalities in the lungs and heart in the next couple of years.”

The Story Behind StethoMe

The initial steps towards building StethoMe were taken by Radomski and co-founders Paweł Elbanowski and Marcin Szajek, who Radomski has been running an IT company with for over 10 years.
“We decided that we want to use our experience in the IT world and connect it with medicine. In fact, I came to idea that we could use our experience, the money that we earned, and the connections that we have in creating something bigger that will help more people in the world,” said Radomski.
StethoMeRadomski and his coworkers listed a sponsored post to Facebook seeking doctors who had problems they felt IT could solve, at which point they came across their new co-founders. Honorata Hafke-Dys and Jędrzej Kocińsk were not physicians, but were PhD’s from the University from Acoustics that presented this real-life problem Radomski and colleagues could solve with their IT expertise. At the time, Hafke-Dys and Kocińsk were parents of children who frequently had respiratory infections. This inspired the two to create a remote stethoscope that could help parents who were in similar circumstances. Together, these five created what is now StethoMe.

An ‘EpiPen’ for spinal cord injuries

An injection of nanoparticles can prevent the body’s immune system from overreacting to trauma, potentially preventing some spinal cord injuries from resulting in paralysis.
The approach was demonstrated in mice at the University of Michigan, with the nanoparticles enhancing healing by reprogramming the aggressive immune cells–call it an “EpiPen” for trauma to the central nervous system, which includes the brain and spinal cord.
“In this work, we demonstrate that instead of overcoming an immune response, we can co-opt the immune response to work for us to promote the therapeutic response,” said Lonnie Shea, the Steven A. Goldstein Collegiate Professor of Biomedical Engineering.
Trauma of any kind kicks the body’s immune response into gear. In a normal injury, immune cells infiltrate the damaged area and clear debris to initiate the regenerative process.
The central nervous system, however, is usually walled off from the rough-and-tumble of immune activity by the blood-brain barrier. A spinal cord injury breaks that barrier, letting in overzealous immune cells that create too much inflammation for the delicate neural tissues. That leads to the rapid death of neurons, damage to the insulating sheaths around nerve fibers that allow them to send signals, and the formation of a scar that blocks the regeneration of the spinal cord’s nerve cells.
All of this contributes to the loss of function below the level of the injury. That spectrum includes everything from paralysis to a loss of sensation for many of the 12,000 new spinal injury patients each year in the United States.
Previous attempts to offset complications from this immune response included injecting steroids like methylprednisolone. That practice has largely been discarded since it comes with side effects that include sepsis, gastrointestinal bleeding and blood clots. The risks outweigh the benefits.
But now, U-M researchers have designed nanoparticles that intercept immune cells on their way to the spinal cord, redirecting them away from the injury. Those that reach the spinal cord have been altered to be more pro-regenerative.
With no drugs attached, the nanoparticles reprogram the immune cells with their physical characteristics: a size similar to cell debris and a negative charge that facilitates binding to immune cells. In theory, their nonpharmaceutical nature avoids unwanted side effects.
With fewer immune cells at the trauma location, there is less inflammation and tissue deterioration. Second, immune cells that do make it to the injury are less inflammatory and more suited to supporting tissues that are trying to grow back together.
“Hopefully, this technology could lead to new therapeutic strategies not only for patients with spinal cord injury but for those with various inflammatory diseases,” said Jonghyuck Park, a U-M research fellow working with Shea.
Previous research has shown success for nanoparticles mitigating trauma caused by the West Nile virus and multiple sclerosis, for example.
“The immune system underlies autoimmune disease, cancer, trauma, regeneration–nearly every major disease,” Shea said. “Tools that can target immune cells and reprogram them to a desired response have numerous opportunities for treating or managing disease.”

Coping strategy therapy for family dementia carers works long-term

A programme of therapy and coping strategies for people who care for family members with dementia successfully improves the carers’ mental health for at least a six-year follow-up, finds a UCL study.
Carers who took part in the programme were five times less likely to have clinically significant depression than carers who were not offered the therapy, according to the findings published in the British Journal of Psychiatry.
The intervention has also been shown to be cost-effective in a prior study.
“Taking care of a family member with dementia can be immensely difficult, particularly as their condition deteriorates and they may not appreciate their carer, so close to four in 10 family carers experience depression of anxiety,” said Professor Gill Livingston (UCL Psychiatry), the trial’s principal investigator.
“We now can offer an evidence-based approach to support their mental health in the short- and long-term, which benefits both the carer and the person they’re caring for.”
The START (STrAtegies for RelaTives) programme is delivered by psychology graduates, trained and supervised by the research team, instead of qualified clinicians, making it easy to implement in many settings.
Those delivering the therapy work with carers to develop coping strategies, supporting them to manage their own wellbeing in the long run without needing further therapy sessions. Carers received eight sessions during which there is an emphasis on planning for the future and accessing further support if needed.
260 family carers took part in the trial, most of whom were caring for a family member who had only recently been diagnosed with dementia. 173 of the participants were enrolled in the START programme for a two-year period and the other 87 were randomly assigned to a control group that did not receive the intervention.
Six years after receiving the therapy, the carers who were in the START programme had significantly fewer symptoms of depression and anxiety, and the researchers say the therapy programme appeared to be both preventative and improve existing mental ill-health.
Patient-related costs were close to three times lower among the families in the START programme (averaging £5759 for those in START versus £16 964 in the control group in year six), which the researchers say is likely due to the carers being more able to cope and provide care for their loved one.
The difference of patient-related costs did not reach statistical significance, but the researchers say this is due to the fact medical costs can be very large and variable. However, their results do strongly suggest the programme is not only cost-effective, but could save money for healthcare services.
“We’ve designed our programme to keep costs low, and our results suggest it could actually result in cost savings in the longer term as dementia patients will have fewer costly medical problems if their family carer is healthy and supported,” said Professor Livingston.
The START team have developed manuals to make it easier for any healthcare provider to deliver the intervention, and plan to provide accredited training at UCL in the near future. Alzheimer’s Society are supporting the team to explore different options for getting the intervention further implemented into practice, and provided funding to make cultural adaptations to widen access to minority ethnic groups. The training manuals are also available in Japanese and Spanish, and are currently being translated into Urdu.
James Pickett, Head of Research at Alzheimer’s Society, said: “Being a carer can be a gruelling job; physically and emotionally demanding, 24 hours a day and often done purely out of love. Unfortunately, depression and anxiety can be an inevitable side effect – with 90% of carers telling us they experience stress and anxiety several times a week. Yet, for the 700,000 carers across the UK, many receive little or no support, despite NICE guidelines recommending that they do.
“This is a major breakthrough. We are absolutely thrilled to see this monumental evidence that START is clinically effective at reducing depression and anxiety in carers, and that the effects can still be seen six years later. This could turn the tide for carers and we would love for it to be available to all people who care for someone with dementia. Alzheimer’s Society is delighted to be supporting the further development and implementation of the START programme so as many people can benefit as possible.”
Shirley Nurock, a former carer who worked on the project as a liaison with the families, commented: “After my husband developed Alzheimer’s disease in his 50s, I spent 15 years caring for him. I was stressed and anxious throughout, feeling powerless as I watched him deteriorate, torn between prioritizing care for him, seeing my children through their teenage years and keeping an eye on my ageing parents.
“I can see now that an intervention like START would have allayed some of my earlier anxieties by giving me appropriate practical information, advice about services, support, coping strategies, and helping me learn how to relax. Learning that it can have such long-term effects is extremely encouraging.”

Rise in early onset colorectal cancer not aligned with screening trends

A new study finds that trends in colonoscopy rates did not fully align with the increase in colorectal cancer (CRC) in younger adults, adding to evidence that the rise in early onset CRC is not solely a result of more detection. The study is published early online in the Journal of Medical Screening.
CRC incidence rates are declining rapidly in adults older than 55 years in the US, partly because of the widespread uptake of colonoscopy, which can remove precancerous growths, lowering incidence rates. In contrast, CRC incidence in younger adults is rising.
There remains debate whether the rise in incidence in younger adults reflects an actual increase in disease, or rather increased detection as a result of more colonoscopies being performed over time.
To add clarity to this debate, American Cancer Society researchers led by Stacey Fedewa, Ph.D. determined past-year colonoscopy rates among more than 50,000 respondents ages 40-54 in the National Health Interview Survey data. Colorectal cancer incidence rates and incidence rate ratios were calculated based on 18 population-based Surveillance Epidemiology and End Results registries during the same period.
Between 2000 and 2015, past-year colonoscopy rates were fairly stable among people aged 40-44 (remaining under 3%), while colorectal cancer incidence rates increased by 28%. Among those ages 45-49, colonoscopy rates doubled (from 2.5% in 2000 to 5.2% in 2015), while colorectal cancer incidence rates increased by 15%. In those ages 50-54, colonoscopy rates increased by about 2.5 times (from 5.0% to 14.1%), while incidence rates rose 17%.
If the growing incidence of young onset CRCs were a result of more detection, larger increases in early-stage diagnoses would be anticipated because screening is most likely to detect localized disease. To investigate this, researchers examined stage-specific CRC incidence trends from 2000-2015. Increases for localized stage disease occurred in ages 40-44, among whom colonoscopy was stable, but not in ages 45-49, among whom colonoscopy had increased. However, distant stage disease increased in every age group, and was steeper (2.9% per year) than that for localized stage (1.1% per year) in ages 40-44 years.
“The changes in past-year colonoscopy rates did not fully align with the rise in overall and distant stage colorectal cancer incidence rates in all three age groups during the corresponding period,” said Dr. Fedewa. “There were some concordant patterns, like the rise in both colonoscopy and early stage incidence among 50-54 years, but there were also some discordant patterns, such as the lack of increase in colonoscopy among people in their early 40’s to match the increasing rates of CRC in this age group.”
“Future studies should examine reasons for the rising CRC incidence rates in young adults,” the study concludes.
