A novel concept of an acoustic ultrasound wearable for early detection of implant failure.

Mechanical failure of medical implants, especially in orthopedic poses a significant burden to the patients and healthcare system. The majority of the implant failures are diagnosed at very late stages and are of mechanical causes. This makes the diagnosis and screening of implant failure very challenging.

Diabetic ulcers are chronic wounds that are notoriously difficult to treat, leading to significant physical and psychological distress and increased healthcare costs. Their multifactorial aetiology necessitates long-term interdisciplinary collaboration and various complementary treatment measures. While numerous studies suggest that electrical stimulation (ES) positively impacts diabetic ulcer healing, the robustness and consistency of these findings require further evaluation to optimize clinical application.

This study proposes a closed-loop brain-machine interface (BMI) based on spinal cord stimulation to inhibit epileptic seizures, applying a semi-supervised machine learning approach that learns from Local Field Potential (LFP) patterns acquired on the pre-ictal (preceding the seizure) condition.LFP epochs from the hippocampus and motor cortex are band-pass filtered from 1 to 13 Hz, to obtain the time-frequency representation using the continuous Wavelet transform, and successively calculate the phase lock values (PLV). As a novelty, the-score-based PLV normalization using both modified-means and Davies-Bouldin's measure for clustering is proposed here.

Department of Rheumatology, Saint-Philibert Hospital, Catholic University of Lille, Lomme, France.
Article Synopsis
- This study compares two types of transcutaneous neurostimulation (TENS) for treating chronic radicular pain: conventional high-frequency low-intensity current (c-TENS) vs. mixed current (m-TENS), which combines c-TENS with low-frequency high-intensity current.
- Seventy-four patients with chronic neuropathic pain participated in the trial and received both treatments in a randomized order over a month; the primary outcome measured was pain level using a Visual Analog Scale (VAS).
- Results showed no significant difference in pain relief between c-TENS and m-TENS, with similar tolerance levels for both, indicating that there’s no clear preference for either treatment method in managing chronic neuropathic radicular pain.
Precipitation patterns strongly affect vertical migration and methylation of mercury in legacy contaminated sites.

College of Environmental & Resource Science, Zhejiang University, Hangzhou, 310058, China.
Article Synopsis
- Legacy-contaminated sites can leak mercury into the environment, which is harmful to both nature and people.
- When it rains a lot (especially frequently), mercury moves deeper into the soil more than when it rains heavily but less often.
- Rain also helps certain microbes turn mercury into a more toxic form called methylmercury, which can create bigger problems for the environment.
