Does Somatosensory-Evoked Potential Simultaneously Decrease with Transcranial Motor-Evoked Potential Alarm? A Multicenter Study by the Monitoring Committee of the Japanese Society for Spine Surgery and Related Research.

Introduction: Multimodal intraoperative neurophysiological monitoring (IONM)-such as monitoring muscle-evoked potentials after transcranial electrical stimulation (Tc-MEP) with somatosensory-evoked potential (SEP) after electrical stimulation of the peripheral nerve-is recommended in spine surgeries to prevent iatrogenic neurological complications. However, the effect of using Tc-MEP with SEP to protect against neurological complications, particularly motor function, remains unknown. In clinical settings, changes due to Tc-MEP meeting the alarm points must be a potential neurological injury.

Mid-term outcomes of distal tibial oblique osteotomy for rheumatoid arthritis-associated ankle arthropathy: A comparison with osteoarthritis outcomes.

Background: Distal tibial oblique osteotomy (DTOO) has traditionally been contraindicated in 'patients with rheumatoid arthritis (RA)'. However, with advances in RA treatment, an increasing number of patients present with arthritis resembling osteoarthritis (OA), suggesting DTOO as a potential option. This study aimed to compare mid-term clinical and radiographic outcomes of DTOO between the patients with OA and RA.

Cardiology involvement and mortality in adult patients with advanced solid cancer complicated by atrial fibrillation.

Background: The association between comorbid atrial fibrillation (AF) and survival in adult patients with advanced solid cancer, as well as the impact of cardiology involvement in such patients, remains unclear.

Methods: This retrospective cohort study included adult patients diagnosed with advanced solid cancers. We calculated prevalence of AF in different cancer types and compared all-cause mortality between patients with and without AF.

Practical X-ray gastric cancer diagnostic support using refined stochastic data augmentation and hard boundary box training.

Endoscopy is widely used to diagnose gastric cancer and has a high diagnostic performance, but it must be performed by a physician, which limits the number of people who can be diagnosed. In contrast, gastric X-rays can be taken by radiographers, thus allowing a much larger number of patients to undergo imaging. However, the diagnosis of X-ray images relies heavily on the expertise and experience of physicians, and few machine learning methods have been developed to assist in this process.

New Surgical Approach and Rehabilitation After Cemented Total Ankle Arthroplasty.

Background: According to the conventional postoperative procedure after total ankle arthroplasty (TAA) for end-stage osteoarthritis (OA) and rheumatoid arthritis (RA), mobilization and weight-bearing are currently started after completion of wound healing. Recently, an early rehabilitation program after cemented TAA with a modified anterolateral approach has been attempted because this approach could provide stable wound healing. To investigate the possibility of expediting rehabilitation, this study evaluated the feasibility, safety, and universality of an early rehabilitation program after cemented TAA using a modified anterolateral approach, even when a surgeon was completely changed.
