Advancing SSVEP-BCI Decoding: Cross-Subject Transfer Learning and Short Calibrated Approach with ELM-AE.

The Steady-State Visually Evoked Potential (SSVEP) is a robust paradigm for developing a high-speed Brain-Computer Interface (BCI). However, one of the challenges of BCI is to face the variability of EEG signals between subjects to reduce or eliminate the time calibration process for a new subject (target subject). Some approaches propose linearly transforming; however, it limits the ability to capture complex and nonlinear relationships in data.

Intercostal serratus plane block versus posterior quadratuus lumbar block in laparoscopic nephrectomy: A randomized, controlled, double-blind study.

Background: Even though laparoscopic nephrectomy improves the quality of postoperative recovery, it still causes moderate to severe pain. Our objective was to determine whether serratus intercostal plane block (SIPB) was noninferior to posterior quadratus lumborum block (QLB) in terms of pain control and quality of recovery.

Methods: This multicentre, controlled, randomized, blinded study had a sample size of 120 patients who were randomly assigned to SIPB, QLB, and control groups prior to scheduled laparoscopic nephrectomy.

Gait speed according to cognitive status in older adults: a cross-sectional study in a resource-limited country.

Objective: We aimed to investigate the association between gait speed and cognitive status in outpatient older adults from a resource-limited setting in Peru.

Methods: We performed a cross-sectional study including older adults aged ≥60 years attending a geriatrics outpatient clinic between July 2017 and February 2020. Gait speed was measured over a 10-meters distance without considering the first and last meter traveled.

Assessment of the Effectiveness of Obstructive Sleep Apnea Treatment Using Optical Coherence Tomography to Evaluate Retinal Findings.

Retinal findings may change in patients with obstructive sleep apnea syndrome (OSAS). The present study aims to evaluate several retinal findings, such as macula layer thickness, the peripapillary retinal nerve fiber layer, and the optic nerve head in patients with OSAS, using optical coherence tomography (OCT); it also aims to monitor the result of several types of treatment of OSAS with OCT. A prospective comparative study was designed.
