Gait-Guard: Turn-aware Freezing of Gait Detection for Non-intrusive Intervention Systems.
IEEE Int Conf Connect Health Appl Syst Eng Technol
June 2024
Freezing of gait significantly reduces the quality of life for Parkinson's disease patients by increasing the risk of injurious falls and reducing mobility. Real-time intervention mechanisms promise relief from these symptoms, but require accurate real-time, portable freezing of gait detection systems to be effective. Current real-time detection systems have unacceptable false positive freezing of gait identification rates to be adopted by the patients for real-world use.

- The study aimed to evaluate the risk and prevalence of hospital-acquired bacterial infections in intensive care units during the first wave of COVID-19 by using advanced deep-sequencing techniques.
- Conducted in a hard-hit region in northern Italy, the research involved collecting and analyzing samples from patients in both regular wards and ICUs to identify specific bacterial pathogens.
- The findings highlighted the effectiveness of this novel sequencing approach in tracking bacterial transmission and understanding antimicrobial resistance during a time of increased patient load.
Introduction: Most people with Parkinson's disease (PD) will experience gait problems. Previous studies demonstrated improved gait and balance after vibration stimulation was applied to the feet of PD patients. However, not all study participants showed improvement, perhaps due to sub-optimal vibration stimulus.

Tremor is a common symptom among Parkinson's disease (PD) patients at all stages. To measure tremor, we utilized IMU sensing data from the wrists while PD patients were drawing. With 30 patients' IMU sensing data obtained from standard tremor rating scale activities, we conducted data analysis for identifying any tremor episodes and extracting tremor amplitude.

- Yemen has been facing the largest cholera outbreak in modern history since 2016, with a significant rise in multidrug-resistant (MDR) cholera strains observed since 2018.
- Analysis of 260 V. cholerae isolates from 2018 to 2019 revealed that a majority (84%) were part of the O1 serogroup and belonged to the seventh pandemic El Tor lineage, while the remaining 16% were non-toxigenic strains from different lineages.
- The emergence of MDR plasmids in cholera strains indicates a potential genetic exchange between epidemic and endemic strains, underscoring the need for ongoing genomic surveillance to manage and control cholera effectively.
