Deep Learning-Based Temporal Gait Analysis Using a Smartphone IMU in Older Adults with and Without Non-Specific Low Back Pain

Accurate gait event detection using inertial measurement units (IMUs) is essential for temporal gait analysis, but frame-level detection is challenged by sparse initial contact (IC) and foot-off (FO) events. This study evaluated recurrent neural network architectures and training...

ReVita: home-based transcutaneous auricular vagus nerve stimulation for reducing pathological fatigue in chronic neurological and post-infectious conditions—study protocol for a randomized, double-blind, sham-controlled trial

Abstract Background Pathological fatigue is one of the most prevalent and disabling symptoms across chronic neurological, post-infectious, and inflammatory diseases, yet effective treatments remain limited. Transcutaneous auricular vagus nerve stimulation (taVNS) is a safe, non-i...

Subgroup variations in effectiveness of femoropopliteal sirolimus versus paclitaxel-coated balloon angioplasty: post hoc results of the randomised SIRONA trial

INTRODUCTION: The randomised SIRONA trial showed that sirolimus-coated balloon (SCB) angioplasty was non-inferior to paclitaxel-coated balloon angioplasty (PCB) regarding femoropopliteal primary patency. There was no difference in clinically driven target lesion revascularisation...

Characterisation and management of therapy-interrupting system errors associated with the use of the HomeChoice cycler for automated peritoneal dialysis

Abstract Background Methodological and technical education of nurses is required to address challenges of technology integration in peritoneal dialysis (PD). We analysed the nature of therapy interrupting system errors in automated peritoneal dialysis (APD) cyclers of a German PD...

Depressive symptoms in amyotrophic lateral sclerosis: associations with quality of life, disease progression and perceived social support—a German multicenter study

BACKGROUND: Amyotrophic Lateral Sclerosis (ALS) is a rapidly progressive, fatal neurodegenerative disease. Patients with ALS are at increased risk of developing depressive symptoms. A clearer understanding of the associations between depressive symptoms, disease progression, heal...

Biomarkers of systemic disease burden and outcomes after transcatheter tricuspid edge-to-edge repair

Abstract Background Risk stratification after transcatheter tricuspid edge-to-edge repair (T-TEER) remains challenging, particularly in patients with advanced right-sided heart failure and systemic disease burden. Biomarkers reflecting inflammation, stress response and multiorgan...

Advances and challenges in powder flowability and fluidization quality

Flowability and fluidization quality of bulk solids are closely interlinked and decisive for the processing behavior and homogeneity of product quality in many applications, ranging from fine chemicals to energy generation. In this perspective, we summarize recent advances in the...

Effect of Heating Tube Configuration on Hydrogen Production via Propane Steam Reforming: A Numerical Study

The hydrogen energy has received considerable attention in recent years due to escalating global concerns over climate change. Hydrogen production relies mainly on steam reforming, an endothermic process that requires external heat. Because of this, the rate of heat transfer with...

Comparison and Reliability of Inertial Sensor-Based Gait Data Acquisition Across Three Shank-Mounted Smartphone Configurations in Older Adults

About the Project This dataset was collected within the Spine Interactive project. The aim was to examine whether IMU time series recorded with three different smartphones are comparable during 2-minute treadmill walking trials in older adults. The devices were an iPhone 15 Pro,...
