Shorter interval to surgery after self-expanding metallic stent may result in better oncologic outcomes in colon cancer obstruction.

Introduction: Colon cancer obstruction is one of the most serious conditions in colorectal surgery. However, the use of self-expanding metallic stent (SEMS) has made it possible to avoid emergency surgery and stoma creation, therefore enabling minimally invasive surgery and one-stage operation. In this study, we aimed to investigate whether there is an optimal interval from SEMS to surgery for the best long-term oncologic outcomes.

Treatment of Pelvic and Spinal Bone Metastases: Radiotherapy and Hyperthermia Alone vs. in Combination.

Painful pelvic and spinal bone metastases are a considerable challenge for doctors and patients. Conventional therapies include morphine-equivalent medication (MeM) and local radiotherapy (RT), but these interventions are not always successful. More recently, hyperthermia (HT) has been applied to complement RT and MeM, and this complex approach has shown promising synergistic results.

Hypopharyngeal reconstruction is a surgically challenging procedure, and postoperative management is important due to a high rate of complications following surgery. In particular, stricture and fistula formation is the most common long-term postoperative complication. Through systematic review and meta-analysis of 21 studies, a significant radiation effect of stricture and fistula formation was found in patients who underwent hypopharyngeal reconstruction.

High Performance Field-Effect Transistors Based on Partially Suspended 2D Materials via Block Copolymer Lithography.

Although various two-dimensional (2D) materials hold great promise in next generation electronic devices, there are many challenges to overcome to be used in practical applications. One of them is the substrate effect, which directly affects the device performance. The large interfacial area and interaction between 2D materials and substrate significantly deteriorate the device performance.

Hierarchical Self-Assembly of Thickness-Modulated Block Copolymer Thin Films for Controlling Nanodomain Orientations inside Bare Silicon Trenches.

We study the orientation and ordering of nanodomains of a thickness-modulated lamellar block copolymer (BCP) thin film at each thickness region inside a topological nano/micropattern of bare silicon wafers without chemical pretreatments. With precise control of the thickness gradient of a BCP thin film and the width of a bare silicon trench, we successfully demonstrate (i) perfectly oriented lamellar nanodomains, (ii) pseudocylindrical nanopatterns as periodically aligned defects from the lamellar BCP thin film, and (iii) half-cylindrical nanostructure arrays leveraged by a trench sidewall with the strong preferential wetting of the PMMA block of the BCP. Our strategy is simple, efficient, and has an advantage in fabricating diverse nanopatterns simultaneously compared to conventional BCP lithography utilizing chemical pretreatments, such as a polymer brush or a self-assembled monolayer (SAM).

Useful Extension of a Retroauricular Hairline Incision in a Parotidectomy Provides Coverage of a Preauricular Skin Defect.

Various incision methods have been widely introduced such as retroauricular hairline incision, modified Blair incision, or face-lift incision.

Neutral-layer-free directed self-assembly of block copolymer in trench using capillary force-induced meniscus.

We propose trench-directed self-assembly (TDSA) of a block copolymer (BCP) driven by a capillary force-induced meniscus as a facile scalable nanolithography method. Unlike conventional directed self-assembly methods, TDSA enables the achievement of neutral surface-free vertical orientations of the BCP nanopatterns irrespective of the polarizability of the substrate, which may be, for example, a ceramic (SiO) on Semiconductor (Si). In our demonstration of the proposed method, we generated various morphologies of the BCP nanopatterns by varying the trench width, and molecular weight of the BCP.

Prognosis of Patient With Resorbable Plates and Screws Under the Incision Site.
