Favorable long-term outcomes of autoimmune nodopathy with mycophenolate mofetil.

Autoimmune nodopathy (AN) is a rare immune-mediated neuropathy characterized by autoantibodies against nodal or paranodal proteins. Patients with AN generally respond poorly to immunoglobulin therapy, and as a newly defined condition, there are currently no established treatment guidelines. Although rituximab shows potential as a therapeutic option, its high cost, limited availability, and the need for infusion monitoring hinder its use as a first-line treatment in many countries.

Clinical evaluation of usefulness and effectiveness of sitting-type continuous passive motion machines in patients with total knee arthroplasty: a dual-center randomized controlled trial.

Background: Total knee arthroplasty (TKA) is a treatment option for osteoarthritis of the knee. After undergoing TKA, patients can be treated with continuous passive motion (CPM); however, inconsistent results have been reported on the effectiveness of CPM as part of a rehabilitation strategy. This discrepancy may be due to the difference between the set-arc of CPM and real arcs of knee motion.

Impact of eating duration on weight management, sleeping quality, and psychological stress: A pilot study.

The daily eating window significantly impacts weight and metabolic health, yet its ideal duration remains uncertain. Thirty-four healthy middle-aged women were randomly assigned to two intervention groups: 8-h time-restricted eating (TRE) and 14-h time-extended eating (EXE). Each intervention lasted 4 wk, with a 16-d washout period before switching to the other intervention.

Resolution dependence of vessel size index across various brain regions.

Magnetic resonance imaging (MRI) excels at detecting quantitative changes in microvascular parameters such as cerebral blood volume, cerebral blood flow, and vessel size index (VSI), which are essential for diagnosing and monitoring cerebrovascular diseases. Absolute VSI estimation, often utilizing superparamagnetic iron oxide nanoparticles as contrast agents, relies on measuring transverse relaxation rates (∆R and ∆R). This study systematically investigates the spatial resolution dependence of VSI using Monte Carlo simulations and in vivo rat brain MRI experiments.

Radiation-induced exosomal miR-21 enhances tumor proliferation and invasiveness in breast cancer: implications for poor prognosis in radiotherapy patients.

Radiotherapy is widely used as an effective non-surgical strategy to control malignant tumors. However, recurrence is one of common causes of treatment failure even after the effective radiotherapy. In this study, we focused on the effects of radiation-induced exosomal miR-21 on the tumor microenvironment to investigate the causes of recurrence.

Long-term treatment outcomes of popliteal artery entrapment syndrome by the Korean Rare Vascular Ailment Research Experts.

Objective: Popliteal artery entrapment syndrome (PAES) results from an anomalous relationship between the popliteal artery and the myofascial structures of the popliteal fossa. The long-term treatment outcomes are not well-known because of the rarity of the disease. This study aimed to establish a nationwide collective dataset and analyze treatment outcomes.

Second-victim distress, organizational support, and interprofessional collaboration and posttraumatic growth in nurses.

Aim: To examine the prevalence of second-victim distress among nurses and the association of second-victim distress, organizational support, and interprofessional collaboration with posttraumatic growth.

Background: Medical errors are unavoidable in healthcare; however, when acknowledged and shared, they offer healthcare professionals an opportunity to learn and grow. Second-victim distress arises from learning from mistakes but can be stressful for nurses, prompting some to leave the profession.

Efficacy of ETB-F01, Heat-Killed Strain EB-AMDK19, in Patients with Respiratory Symptoms: A Multicenter Clinical Trial.

Respiratory symptoms are prevalent in the general population, and they are associated with a decline in lung function and increased mortality. The gut-lung connection suggests intestinal dysbiosis may impact lung diseases, with showing promise in regulating extraintestinal diseases. However, its application in patients with respiratory symptoms lacks clinical trial evidence.

Concurrent Versus Sequential Adjuvant Capecitabine-Based Chemoradiation in Residual Triple-Negative Breast Cancer After Neoadjuvant-Chemotherapy: A Multicenter Comparative Study.

Recent studies have indicated a connection between cervical cancer and the uterine microbiome, underscoring its importance. This study explored the potential of liquid-based cytology (LBC) samples, which are typically used for cytological analysis, in investigating the cervical microbiome.

Nano-fluorescence imaging: advancing lymphatic disease diagnosis and monitoring.

The lymphatic system plays a crucial role in maintaining physiological homeostasis and regulating immune responses. Traditional imaging modalities such as magnetic resonance imaging, computerized tomography, and positron emission tomography have been widely used to diagnose disorders in the lymphatic system, including lymphedema, lymphangioma, lymphatic metastasis, and Castleman disease. Nano-fluorescence technology has distinct advantages-including naked-eye visibility, operational simplicity, portability of the laser, and real-time visibility-and serves as an innovative alternative to traditional imaging techniques.
