A Multi-Center, Open-Label, Single-Arm Study to Investigate the Early Effectiveness of Esketamine Nasal Spray in Patients with Treatment-Resistant Depression Using a Mobile Self-Monitoring Application.

This study assesses the early effectiveness of esketamine nasal spray (ESK) in adults with treatment-resistant depression (TRD) 1 day after the first administration, as monitored through self-assessment via the mobile application, Esketamine Continuing Assessment for Relapse Prevention (EsCARe). In this multi-center, open-label, single-arm study, adults aged 18-65 years diagnosed with TRD after failing at least two antidepressant therapies were enrolled from five tertiary hospitals in South Korea. During the induction period, participants self-administered ESK twice weekly and used the EsCARe app daily to record mood, sleep, and somatic symptoms.

Impact of Atrial Fibrillation with Rapid Ventricular Response on Atrial Fibrillation Recurrence: From the CODE-AF Registry.

This study investigated the impact of RVR on the recurrence of AF. : Data were obtained from a multicenter, prospective registry of non-valvular AF patients.

Impact of Point-of-Care Lactate Testing for Sepsis on Bundle Adherence and Clinical Outcomes in the Emergency Department: A Pre-Post Observational Study.

: The early diagnosis and prompt treatment of sepsis can enhance clinical outcomes. This study aimed to assess the relationship between point-of-care testing (POCT) for lactate levels and both adherence to the Surviving Sepsis Campaign (SSC) guidelines and mortality rates among sepsis patients in the emergency department (ED). We hypothesized that bedside lactate POCT would lead to better clinical outcomes.

Evaluating lead-free alternatives for radiation shielding in diagnostic radiology: a case study from a tertiary general hospital in Korea.

With the continued increase in the number of pieces of diagnostic medical radiography equipment being used, radiation shielding in radiology departments is becoming increasingly important. Lead is the most commonly used material for radiation protection; however, there are numerous disadvantages associated with the use of lead, including environmental hazards and harm to the human body. Alternative shielding materials that can be used as replacements include barium sulfate, tungsten, or bismuth.

Nationwide precision oncology pilot study: KOrean Precision Medicine Networking Group Study of MOlecular profiling-guided therapy based on genomic alterations in advanced solid tumors (KOSMOS) KCSG AL-20-05.

Background: Next-generation sequencing (NGS) has become widely available but molecular profiling-guided therapy (MGT) had not been well established in the real world due to lack of available therapies and expertise to match treatment. Our study was designed to test the feasibility of a nationwide platform of NGS-guided MGT recommended by a central molecular tumor board (cMTB) for metastatic solid tumors.

Patients And Methods: Patients with advanced or metastatic solid tumors with available NGS results and without standard treatment were enrolled.

Cardiovascular outcomes in Parkinson's disease patients from a retrospective cohort study.

Parkinson's disease (PD) reports high rates of morbidity and mortality, but the risk of adverse cardiovascular outcomes in patients with PD has not been fully elucidated. This bi-center retrospective cohort study using the electronic health records (EHR) database of two tertiary hospitals screened a total of 327,292 subjects who visited the outpatient clinic, and 1194 patients with PD were propensity score-matched with a control population. The primary outcome was the occurrence of major adverse cardiovascular events (MACE).

Efficacy and safety of SKCPT in patients with knee osteoarthritis: A multicenter, randomized, double-blinded, active-controlled phase III clinical trial.

Ethnopharmacological Relevance: Osteoarthritis (OA) is the most prevalent type of arthritis worldwide and a leading cause of years lost to pain and disability. Among the current pharmacological treatments for OA, symptomatic slow-acting drugs for OA (SYSADOA) induce pain relief and aim to improve joint function by relieving inflammation while causing fewer gastrointestinal and cardiovascular adverse events than non-steroidal anti-inflammatory drugs (NSAIDs). SKCPT is a herbal SYSADOA formulated from Clematis mandshurica, Trichosanthes kirilowii, and Prunella vulgaris powdered extracts.

Stage Evaluation of Cystic Duct Cancer.

Purpose: Cystic duct cancers (CDCs) have been classified as extrahepatic bile duct cancers or gallbladder cancers (GBCs); however, it is unclear whether their clinical behavior is similar to that of distal extrahepatic bile duct cancers (DBDCs) or GBCs.

Materials And Methods: T category of the CDCs was classified using current T category scheme of the GBCs and DBDCs, and clinicopathological factors were compared among 38 CDCs, 345 GBCs, and 349 DBDCs. We modified Nakata's classifications (type 1, confined within cystic duct (CD); combined types 2-4, extension beyond CD) and compared them.

Machine Learning Based Abnormal Gait Classification with IMU Considering Joint Impairment.

Gait analysis systems are critical for assessing motor function in rehabilitation and elderly care. This study aimed to develop and optimize an abnormal gait classification algorithm considering joint impairments using inertial measurement units (IMUs) and walkway systems. Ten healthy male participants simulated normal walking, walking with knee impairment, and walking with ankle impairment under three conditions: without joint braces, with a knee brace, and with an ankle brace.

Effect of Light Irradiance and Curing Duration on Degree of Conversion of Dual-Cure Resin Core in Various Cavities with Different Depths and Diameters.

(1) Background: To compare the degree of conversion of resin cores in various types of cavities and determine an effective irradiation method for achieving a higher degree of conversion. (2) Methods: Four different-sized cavities (narrow-shallow, narrow-deep, wide-shallow, and wide-deep) were simulated using a Teflon mold. The light irradiance reaching the bottom of each mold was measured by positioning a radiometer.

Purpose: This experiment aimed to observe the differences in biological properties by producing BGS-7 + PCL scaffolds with different weight fractions of BGS-7 through 3D printing and to confirm whether using the scaffold for vertical bone augmentation is effective.

Materials And Methods: Cube-shaped bioglass (BGS-7) and polycaprolactone (PCL) scaffolds with different weight fractions (PCL alone, PCL with 15% and 30% BGS-7) are produced using 3D printing. The surface hydroxyapatite (HA) apposition, the pH change, proliferation and attachment assays, and various gene expression levels are assessed.

Drug-coated balloon versus drug-eluting stent for femoropopliteal total occlusions: intraluminal versus subintimal approaches.

Because there is a lack of comparative studies assessing drug-coated balloon (DCB) and drug-eluting stent (DES) outcomes with respect to intraluminal (IL) and subintimal (SI) approaches in femoropopliteal (FP) total occlusive lesions, we compared the outcomes between DCB (including bailout stenting) and DES treatments for this lesion. A total of 487 limbs (434 patients) were divided into the IL (n = 344, DCB: n = 268, DES: n = 76) and SI (n = 143, DCB: n = 83, DES: n = 60) approach groups. The primary outcome was a major adverse limb event (MALE), defined as above-ankle amputation or repeat revascularization of the index limb.
