AI app could help diagnose HIV more accurately

AI app could help diagnose HIV more accurately | healthcare technology | Scoop.it

More than 100 million HIV tests are performed around the world annually, meaning even a small improvement in quality assurance could impact the lives of millions of people by reducing the risk of false positives and negatives.

 

Academics from the London Center for Nanotechnology at UCL and AHRI used deep learning (artificial intelligence/AI) algorithms to improve health workers' ability to diagnose HIV using lateral flow tests in rural South Africa.

 

Their findings, published today in Nature Medicine, involve the first and largest study of field-acquired HIV test results, which have applied machine learning (AI) to help classify them as positive or negative.

 

By harnessing the potential of mobile phone sensors, cameras, processing power and data sharing capabilities, the team developed an app that can read test results from an image taken by end users on a mobile device. It may also be able to report results to public health systems for better data collection and ongoing care.

nrip's insight:

The use of mobile tools for data capture and AI/ML algorithms for diagnostics and detections has been the inside story of digital health over the past 4 years. This is an excellent study and shows the promise of this combination of technologies in building the future of healthcare. HIV is a pandemic which must be eradicated.

Credit Card-Sized Chip Diagnoses HIV and Provides T Cell Counts on the Spot

Credit Card-Sized Chip Diagnoses HIV and Provides T Cell Counts on the Spot | healthcare technology | Scoop.it

A credit card-sized chip can diagnose HIV infection and provide T cell counts to guide treatment, according to a recent paper in Science Translational Medicine.


The fluid-processing chip provides accurate test results in less than 20 minutes using a single drop of blood that goes directly into the testing chamber and does not require trained handling.


The chip is designed to work in a battery-powered handheld device that would “deliver simple HIV diagnostics to patients anywhere in the world, regardless of geography or socioeconomic status,” the researchers say in the paper.


Nearly 7 in 10 HIV-infected people live in poor parts of the world. Many have to travel long distances to get to a clinic, making coming back for test results a major ordeal.

Acceptability of a Mobile Phone Support Tool for Promoting Adherence to Antiretroviral Therapy Among Young Adults

Acceptability of a Mobile Phone Support Tool for Promoting Adherence to Antiretroviral Therapy Among Young Adults | healthcare technology | Scoop.it

Adherence to treatment is critical for successful treatment outcomes.

 

Although factors influencing antiretroviral therapy (ART) adherence vary, young adults are less likely to adhere owing to psychosocial issues such as stigma, ART-related side effects, and a lack of access to treatment.

 

The Call for Life Uganda (CFLU) mobile health (mHealth) tool is a mobile phone–based technology that provides text messages or interactive voice response functionalities through a web interface and offers 4 modules of support.


Objective: This study aims to describe the acceptability and feasibility of a mobile phone support tool to promote adherence to ART among young adults in a randomized controlled trial.


Methods: An exploratory qualitative design with a phenomenological approach at 2 study sites was used. A total of 17 purposively selected young adults with HIV infection who had used the mHealth tool CFLU from 2 clinics were included. In total, 11 in-depth interviews and 1 focus group discussion were conducted to examine the following topics: experience with the CFLU tool (benefits and challenges), components of the tool, the efficiency of the system (level of comfort, ease, or difficulty in using the system), how CFLU resolved adherence challenges, and suggestions to improve CFLU. Participants belonged to 4 categories of interest: young adults on ART for the prevention of mother-to-child transmission, young adults switching to or on the second-line ART, positive partners in an HIV-discordant relationship, and young adults initiating the first-line ART. All young adults had 12 months of daily experience using the tool. Data were analyzed using NVivo version 11 software (QSR International Limited) based on a thematic approach.


Results: The CFLU mHealth tool was perceived as an acceptable intervention;

 

young adults reported improvement in medication adherence, strengthened clinician-patient relationships, and increased health knowledge from health tips.

 

Appointment reminders and symptom reporting were singled out as beneficial and helped to address the problems of forgetfulness and stigma-related issues.

 

HIV-related stigma was reported by a few young people. Participants requested extra support for scaling up CFLU to make it more youth friendly.

 

Improving the tool to reduce technical issues, including network outages and a period of software failure, was suggested. They suggested that in addition to digital solutions, other support, including the promotion of peer support meetings and the establishment of a designated space and staff members for youth, was also important.


Conclusions: This mHealth tool was an acceptable and feasible strategy for improving ART adherence and retention among young adults in resource-limited settings.

Biggest Innovations in Medical Technology in 2013

Biggest Innovations in Medical Technology in 2013 | healthcare technology | Scoop.it

The field of medical technology is incredibly exciting these days. Each breakthrough has the potential to impact the lives of thousands of patients, sometimes changing the course of medical history and forever improving the human experience. Such can be argued for antibiotics, x-rays, vaccines, or even things as seemingly simple as disposable medical instruments (an extremely important sanitary innovation). Year after year, teams of research physicians and engineers work to advance our knowledge and abilities.


This article reviews some of the most influential medical innovations of the past year. From new insights in the treatment of diabetes to a new type of optical surgical procedure, incredible innovations and advancements have been achieved this year.


Implant Relieving Severe Headache Pain

A new type of neuromodulation therapy has emerged that seems to be an effective treatment for cluster and migraine headaches. Neuromodulation therapy treats a cluster of nerves behind the face that signal headache pain. This device, implanted in the face by way of the mouth, is positioned to stimulate the facial nerve that relieves headaches when stimulated. A separate device, placed on the cheek, activates the device, relieving pain in as quickly as five to ten minutes. 


Bariatric Surgeries Treating Diabetes

Doctors who have performed bariatric surgery, also known as gastric bypass, have noted in the past that many of their patients had gone into diabetes remission as they recovered from surgery. This evidence has some health care professionals advocating gastric bypass treatment as an early tactic for fighting diabetes, instead of as a last-resort effort.


Bee Venom Treats HIV

One toxin found in bee venom, melittin, has been found to destroy HIV particles. Researchers claim that the particles break apart the physical structure of the virus, but are too small to have an impact on other cells within the body. A proposed method for distributing the chemical is a topical virucidal agent.


Detecting Skin Cancer with a Hand-held Device

Caught at an early stage, the survival rate for melanoma is 99 percent. In advanced stages, though, that rate drops to a mere 15 percent.

The good thing about the skin and its relation to cancer is that we can observe it. Visual detection is the best way to prevent advanced stage melanoma. Therefore checking moles and other discoloration on the skin regularly can be the best form of early detection. If a patient notices a change and brings it to the attention of their dermatologist, this new device is able to scan the area and report to the physician whether or not melanoma is present within a few seconds. It works by analyzing a database of over 10,000 images alongside a structural scan of the skin using military-grade optical technology. Clinical trials show that this device is nearly 98% effective.


Cataract Surgery at one Quadrillionth of a Second

Femtosecond laser technology will help improve the outcome in the more than 1.6 million annual cataract surgeries that are performed in the US annually. The apparatus, which separates the tissue by ablating and cleaving it, instead of cutting it, operates in one quadrillionth of a second. Its speed and precision help reduce swelling post-op, allow less time to be spent on the eye, and help the surgeon be more accurate with the implant. Optical surgeons across the globe are eager to implement this new device in order to improve their practice.
