Impact of body mass index on repeat coronary revascularization rates in patients with LDL-C below 55 mg/dL and LDL-C below 70 mg/dL: a 42-month cohort study in Korea.

Background: Previous studies revealed a linear relationship between body mass index (BMI) and repeat coronary revascularization rate in patients who underwent percutaneous coronary intervention (PCI). However, this relationship has not been demonstrated in Korean patients who meet old and new target low-density lipoprotein cholesterol (LDL-C) levels of Korean dyslipidemia guidelines. Therefore, we conducted this study to find out the effect of BMI on repeat coronary revascularization rate in patients with LDL-C <55 mg/dL and patients with LDL-C <70 mg/dL.

Long-term clinical outcomes of image-guided percutaneous coronary intervention in acute myocardial infarction from the Korea Acute Myocardial Infarction Registry.

Imaging modalities for percutaneous coronary intervention (PCI), such as intravascular ultrasound (IVUS) or optical coherence tomography (OCT), have increased in the current PCI era. However, their clinical benefits in acute myocardial infarction (AMI) have not been fully elucidated. This study investigated the long-term outcomes of image-guided PCI in patients with AMI using data from the Korean Acute Myocardial Infarction Registry.

The authors performed this study to investigate the efficacy and safety of a rosuvastatin (RSV)/amlodipine (AML) polypill compared with those of atorvastatin (ATV)/AML polypill. We included 259 patients from 21 institutions in Korea. Patients were randomly assigned to 1 of 3 treatment groups: RSV 10 mg/AML 5 mg, RSV 20 mg/AML 5 mg, or ATV 20 mg /AML 5 mg.

The Comparison of the Associations of Lipoprotein(a) and the Atherogenic Index of Plasma With Coronary Artery Calcification in Patients Without High LDL-C: A Comparative Analysis.

Objective: Lipoprotein(a) (Lp[a]) and the atherogenic index of plasma (AIP) have been reported as predictive markers of coronary artery calcium (CAC). However, previous studies demonstrated that the cardiovascular risk associations with Lp(a) are attenuated in patients with low-density lipoprotein cholesterol (LDL-C) levels ≤135 mg/dL. However, few articles have identified the risk factors of CAC in patients without high LDL-C.

Prolonged Time to Brake Following Lower Extremity Injuries.

Introduction: No guidelines exist for recommending return to driving. This study will examine time to brake (TTB) after lower extremity injuries versus in uninjured people. The potential effect of various types of lower extremity injuries on TTB will be measured.

Drastic Gas Sensing Selectivity in 2-Dimensional MoS Nanoflakes by Noble Metal Decoration.

Noble metal nanoparticle decoration is a representative strategy to enhance selectivity for fabricating chemical sensor arrays based on the 2-dimensional (2D) semiconductor material, represented by molybdenum disulfide (MoS). However, the mechanism of selectivity tuning by noble metal decoration on 2D materials has not been fully elucidated. Here, we successfully decorated noble metal nanoparticles on MoS flakes by the solution process without using reducing agents.

Neuroma as an unusual complication of transarticular lateral release and distal chevron metatarsal osteotomy for hallux valgus: A case report.

Compared to other lateral soft tissue release methods during hallux valgus surgery, the medial transarticular approach has the advantages of being reproducible, safe, and simple. However, a few reports have described the disadvantages of medial transarticular lateral soft tissue release, including only inadequate lateral soft tissue release. Herein, we report a case of intermetatarsal neuroma in the first web space after hallux valgus correction using distal chevron metatarsal osteotomy and medial transarticular lateral soft tissue release.

The efficacy and safety of non-resistance manual therapy in inpatients with acute neck pain caused by traffic accidents: A randomized controlled trial.

Background: Neck pain and functional impairment are common complications of traffic accidents (TAs); however, the effects of manual therapy on these symptoms have rarely been studied in the literature. Thus, this randomized controlled trial aims to assess the effectiveness and safety of non-resistance manual therapy (NRT)-a treatment combining mobilization and pressure release techniques-on acute neck pain caused by TA.

Method: This study will use a two-armed, parallel, assessor-blinded randomized controlled trial design and will be conducted in the Daejeon Jaseng Hospital of Korean Medicine in South Korea.

Surface-Tailored Medium Entropy Alloys as Radically Low Overpotential Oxygen Evolution Electrocatalysts.

Numerous studies have explored new materials for electrocatalysts, but it is difficult to discover materials that surpass the catalytic activity of current commercially available noble metal electrocatalysts. In contrast to conventional transition metal alloys, high-entropy alloys (HEAs) have immense potential to maximize their catalytic properties because of their high stability and compositional diversity as oxygen evolution reactions (OERs). This work presents medium-entropy alloys (MEAs) as OER electrocatalysts to simultaneously satisfy the requirement of high catalytic activity and long-term stability.

Here, the TiO nanorod arrays decorated by edge-rich MoS nanoplates are elaborately synthesized and deposited on p-Si.

Hierarchical Nanoporous BiVO Photoanodes with High Charge Separation and Transport Efficiency for Water Oxidation.

To fabricate high efficiency photoanodes for water oxidation, it is highly required to engineer their nanoporous architecture and interface to improve the charge separation and transport efficiency. By focusing on this aspect, we developed hierarchical nanoporous BiVO (BV) from solution processed two-dimensional BiOI (BI) crystals. The orientation of the BI crystals was controlled by changing the solvent volume ratios of ethylene glycol (EG) to ethanol (ET), which resulted in different hierarchical and planar BV morphologies through a chemical treatment followed by thermal heating.
