Effect of a Smartphone-Based App on the Quality of Life of Patients With Heart Failure: Randomized Controlled Trial.

Research RF Safe Research Library Jan 1, 2020

This randomized controlled trial evaluated whether adding a smartphone-based app to routine care improves quality of life in hospitalized patients with heart failure. Over 3 months, the app group reported significantly better quality-of-life scores than the control group on the Minnesota Living with Heart Failure…

Structural and functional correlates of smartphone addiction

Research RF Safe Research Library Jan 1, 2020

This cross-sectional MRI study compared individuals meeting psychometric criteria for smartphone addiction (n=22) with controls (n=26). It reports lower gray matter volume in several regions (including left anterior insula and parahippocampal cortex) and lower intrinsic activity in the right anterior cingulate cortex…

Oxidative and mutagenic effects of low intensity GSM 1800 MHz microwave radiation

Research RF Safe Research Library Jan 1, 2018

This animal study used developing quail embryos to assess oxidative and mutagenic effects of low-intensity GSM 1800 MHz radiation from a commercial smartphone. The authors report statistically significant increases in oxidative stress markers, DNA integrity damage, and oxidative DNA damage (8-oxo-dG) in exposed…

Using smartphone technology to deliver a virtual pedestrian environment: usability and validation.

Research RF Safe Research Library Jan 1, 2017

This study assessed usability, feasibility, and validity of a smartphone-delivered virtual pedestrian environment by comparing it with a semi-immersive kiosk virtual environment. Among 68 adults, participants used the smartphone system without difficulty, reported no significant simulator sickness, and rated it as…

Demonstration of long-distance hazard-free wearable EEG monitoring system using mobile phone visible light communication.

Research RF Safe Research Library Jan 1, 2017

This paper describes an engineering approach to avoid RF/microwave radiation in wearable EEG data transmission by using visible light communication. The system performance was tested at different illuminance levels and an algorithm for low-illuminance operation was proposed. The authors report error-free transmission…

Smartphone usage and increased risk of mobile phone addiction: A concurrent study.

Research RF Safe Research Library Jan 1, 2017

This cross-sectional online study surveyed Malaysian respondents about smartphone addiction behavior and awareness of electromagnetic radiation (EMR). Most participants reported smartphone dependency and reported being aware of EMR, with no significant difference in addiction behavior by accommodation type (home vs…

Gerontechnologies for Older Patients with Heart Failure: What is the Role of Smartphones, Tablets, and Remote Monitoring Devices in Improving Symptom Monitoring and Self-Care Management?

Research RF Safe Research Library Jan 1, 2016

This review-style article discusses gerontechnologies—mobile applications on smartphones/tablets and remote monitoring systems—for outpatient symptom monitoring and self-care management in older adults with heart failure. It frames these tools as potentially cost-effective and accessible when designed for older…

The relationship between mobile phone location sensor data and depressive symptom severity.

Research RF Safe Research Library Jan 1, 2016

This observational study examined whether passively collected smartphone GPS features relate to depressive symptom severity in 48 college students over 10 weeks. Several mobility features (including location variance, entropy, and circadian movement) were reported to correlate with PHQ-9 scores. Associations were…

Automated ABO Rh-D blood type detection using smartphone imaging for point-of-care medical diagnostics.

Research RF Safe Research Library Jan 1, 2016

This conference paper describes an automated method for ABO and Rh-D blood typing using images captured by low-cost mobile phones of a fabric strip rapid diagnostic test. The approach applies morphological image processing steps including noise reduction, range filtering, and empirically derived heuristics to…

Smartphone, Smart Surgeon, what about a 'Smart Logbook'?

Research RF Safe Research Library Jan 1, 2016

This review assessed surgical and procedural case logbook smartphone applications available in major app stores. Of 2,740 apps screened, 16 were relevant and 11 were suitable for critical review, with reported variation in app size and cost. The authors conclude that current mobile apps can efficiently replace…

Effects of Electromagnetic Radiation from Smartphones on Learning Ability and Hippocampal Progenitor Cell Proliferation in Mice.

Research RF Safe Research Library Jan 1, 2016

This mouse study examined chronic smartphone electromagnetic radiation exposure and its effects on spatial working memory and hippocampal progenitor cell proliferation. The authors report no significant differences in Y-maze spontaneous alternation or BrdU-labeled progenitor proliferation after exposure, but…

Developing a Brief Suicide Prevention Intervention and Mobile Phone Application: a Qualitative Report.

Research RF Safe Research Library Jan 1, 2015

This qualitative report describes phase one of a treatment development study for adolescent suicide prevention, including development of a safety plan smartphone application. Clinicians, parents, and adolescents emphasized transition of care, specific treatment targets, and safety planning as important. All…

Is smartphone a necessity or luxury among orthopedic specialty?

Research RF Safe Research Library Jan 1, 2014

This cross-sectional questionnaire study assessed how orthopaedic residents and consultants in Karachi used smartphones for clinical work and academics. Most respondents owned smartphones and reported using apps and internet/email, but fewer used them to share clinical data. The paper does not assess electromagnetic…

Multifocal Breast Cancer in Young Women with Prolonged Contact between Their Breasts and Their Cellular Phones

Research RF Safe Research Library Jan 1, 2013

This 2013 case series describes four young women (ages 21–39) with multifocal invasive breast cancer who reportedly carried smartphones directly against their breasts in their brassieres for prolonged periods over several years. Tumors were reported to occur in areas immediately underlying phone contact, with imaging…

Optimized flash light-emitting diode spectra for mobile phone cameras.

Research RF Safe Research Library Jan 1, 2013

This engineering study examines how the spectral mismatch between mobile phone flash LEDs and modern display gamuts influences smartphone camera color reproduction. Using a CIECAM02-based metric and an evaluation method grounded in raw camera data and a Digital ColorChecker SG, the authors propose optimized flash LED…
