Substantiating the Therapeutic Effects of Simultaneous Heat Massage Combined with Conventional Physical Therapy for Treatment of Lower Back Pain: A Randomized Controlled Feasibility Trial.

Background: There are various therapeutic options for the conservative management of lower back pain (LBP). A combination of two or more treatment options may be more effective in the clinical management of non-specific LBP. In this study, we compared the effects of simultaneous heat massage with conventional physical therapy in patients with subacute LBP.

Effects of Personal Low-Frequency Stimulation Device on Myalgia: A Randomized Controlled Trial.

Electrotherapy is commonly used for myalgia alleviation. Low-frequency stimulation (LFS) is primarily used for controlling acute and chronic pain and is a non-invasive therapy that can be easily performed with electric stimulation applied on the skin. However, little evidence exists regarding the pain alleviation effects of personal low-frequency stimulation device for home use.

Mechanical Changes of the Lumbar Intervertebral Space and Lordotic Angle Caused by Posterior-to-Anterior Traction Using a Spinal Thermal Massage Device in Healthy People.

Background: The axial (horizontal) traction approach has been traditionally used for treatment of low back pain-related spinal disorders such as nuclear protrusion, primary posterolateral root pain, and lower thoracic disc herniation; however, it is known to have some technical limitations due to reductions of the spinal curve. Lumbar lordosis plays a pivotal function in maintaining sagittal balance. Recently, vertical traction and combination traction have been attracting attention due to improving therapeutic outcomes, although evidence of their clinical application is rare; therefore, this study was conducted to investigate the mechanical changes of lumbar intervertebral space, lordotic angle, and the central spinal canal area through vertical traction treatment using a spinal massage device in healthy participants.

Nickelocene as an Air- and Moisture-Tolerant Precatalyst in the Regioselective Synthesis of Multisubstituted Pyridines.

Ni(COD)-catalyzed cycloaddition reactions to access pyridines have been extensively studied. However, this catalyst typically requires drying procedures and inert-atmosphere techniques for the reactions. Herein, we report operationally simple nickel(0) catalysis to access substituted pyridines from various nitriles and 1,6-diynes without the aid of air-free techniques.

Use of a Spinal Thermal Massage Device for Anti-oxidative Function and Pain Alleviation.

Elderly people are vulnerable to a variety of diseases, including chronic pain, which reduces their levels of physical fitness. Thermal massage has been shown to relieve pain and activate antioxidant enzymes. The objective of this study was to determine whether thermal massaging of the spinal column can reduce muscle pain and induce antioxidant function.

A Review of the Medical Challenges of Using Direct Oral Anticoagulants in Real-World Practice.

Clinical guidelines for management of non-valvular atrial fibrillation or venous thromboembolism currently recommend direct oral anticoagulants as the preferred strategy for antithrombotic treatment. As a result, they are increasingly being used as an alternative to conventional therapy. However, they are unlikely to completely replace conventional approaches, due to a number of existing medical challenges.

Redox-Active Functional Electrolyte for High-Performance Seawater Batteries.

Rechargeable seawater batteries have gained recognition as key sustainable electrochemical systems by employing the near-infinite and eco-friendly catholyte seawater. However, their practical applications have been limited owing to the low chemical and electrochemical stability of the anode component. Herein, a stability-secured approach was developed by using sodium-biphenyl-dimethoxyethane solution as a redox-active functional anolyte for high-performance seawater batteries.

Using non-vitamin K oral anticoagulants in specific patient populations: a study of Korean cases.

Non-vitamin K oral anticoagulants (NOACs) are increasingly used as alternatives to conventional therapies and have considerable accumulated real-world clinical data in patients with non-valvular atrial fibrillation (NVAF) or venous thromboembolism (VTE). However, it is not easy to make a complete changeover to NOACs in real-world clinical practice because NOACs still have challenges in specific patient populations (eg, Asian patients, NVAF patients presenting with acute coronary syndrome [ACS], dialysis patients with NVAF, patients with cancer-associated VTE, etc.).

Real-Time Light-Guided Vocal Fold Injection: Ex Vivo Feasibility Study in a Canine Model.

Objective: The transcricothyroid (CT) membrane approach is a good option for office-based vocal fold injection (VFI). However, because the needle tip is invisible during injection using the CT approach, precise localization requires a high level of experience, and mastering this approach involves a steep learning curve. To overcome current limitations, we conceptualized a novel technique: real-time light-guided VFI (RL-VFI), which enables simultaneous VFI under direct visualization of the lighted needle tip.

How Does "Regulatory Practice" Create Discrepancies in Drug Label Information Between Asian and Western Countries? Different Label Information for Direct Oral Anticoagulants Approved in the United States, Europe, Korea, and Japan.

Globalization of the pharmaceutical industry has continued over the past few decades, and various regulatory authorities have put considerable effort into harmonizing and standardizing drug regulations. However, the regulatory practices of each regulatory authority, in addition to local differences in ethnic, social, and cultural backgrounds, create discrepancies in risk/benefit assessments, regulatory decisions, and drug label information in various countries. This study examines discrepancies in the label information for direct oral anticoagulants approved in the US, Europe, Korea, and Japan and reviews the causes of those discrepancies, focusing on regulatory practices.

Septochoanal Polyp with Metaplastic Ossification Mimicking Sinonasal Tumor: A Case Report.

Choanal polyps are a form of nasal polyps that grow toward the choana with a single stalk. Septochoanal polyp is a rare entity that originates from the mucosa of the nasal septum with choanal extension. The most common site of its origin is mainly the superior aspect of the posterior portion of the nasal septum.

Potential therapeutic mechanism of extremely low-frequency high-voltage electric fields in cells.

The aim of this survey was to provide background theory based on previous research to elucidate the potential pathway by which medical devices using extremely low-frequency high-voltage electric fields (ELF-HVEF) exert therapeutic effects on the human body, and to increase understanding of the AC high-voltage electrotherapeutic apparatus for consumers and suppliers of the relevant devices. Our review revealed that an ELF field as weak as 1-10 μ V/m can induce diverse alterations of membrane proteins such as transporters and channel proteins, including changes in Ca + + binding to a specific site of the cell surface, changes in ion (e.g.

Is 1/f sound more effective than simple resting in reducing stress response?

Background: It has been previously demonstrated that listening to 1/f sound effectively reduces stress. However, these findings have been inconsistent and further study on the relationship between 1/f sound and the stress response is consequently necessary.

Objective: The present study examined whether sound with 1/f properties (1/f sound) affects stress-induced electroencephalogram (EEG) changes.
