Superbly Efficient and Stable Ultrapure Blue Phosphorescent Organic Light-Emitting Diodes with Tetradentate Pt(II) Complex with Vibration Suppression Effect.

Blue phosphorescent organic light-emitting diodes (PHOLEDs) are on the brink of commercialization for decades. However, the external quantum efficiency (EQE) and operational lifetime of PHOLEDs are not yet reached industrial standards. Here, a novel tetradentate Pt(II) emitter with a spirofluorene onto the carbazole unit that minimizes the vibration modes, corresponding to the structural relaxation during the de-excitation, called the vibration suppression effect is reported.

The Decline of Small Practice in Colorectal Surgery: Practice Consolidation From 2015-2022.

Introduction: Physicians have gravitated toward larger group practice arrangements in recent years. However, consolidation trends in colorectal surgery have yet to be well described. Our objective was to assess current trends in practice consolidation within colorectal surgery and evaluate underlying demographic trends including age, gender, and geography.

Traumatic Anterior Tibial Artery Pseudoaneurysm: A Case Report.

Introduction: Traumatic pseudoaneurysms of the limbs are rare, with few cases described in vascular literature. Treatment is variable and dependent upon presentation and impact on local anatomy affected. Rapid assessment can be performed with ultrasound and assist in treatment decisions.

Tracheostomy in high-risk patients on ECMO: A bedside hybrid dilational technique utilizing a Rummel tourniquet.

Objective: Traditionally, critically ill patients requiring prolonged mechanical ventilation benefit from a long-term airway, thus necessitating tracheostomy. The widespread application of extracorporeal membrane oxygenation (ECMO) has exponentially increased in recent years, creating a new subset of patients necessitating tracheostomy with significantly increased bleeding risk. We present a hybrid dilational tracheostomy technique utilizing a Rummel tourniquet developed at our institution to mitigate bleeding risk in patients on ECMO necessitating long-term airway.

Short and long-term oncologic outcomes of patients with colon cancer of the splenic flexure.

Background: There is currently no consensus on surgical management of splenic flexure adenocarcinoma (SFA).

Methods: Patients undergoing surgical resection for SFA between 1993 and 2015 were identified. Postoperative outcomes were compared between patients who underwent segmental (SR) vs.

Outcomes of a Large Series of Laparoscopic Ventral Hernia Repairs after Liver Transplantation.

Background: The hernia defects that develop in liver transplant recipients tend to be complex. Unfortunately, there is a paucity of data to guide post-transplant hernia management. Our goal was to evaluate the outcomes following laparoscopic ventral hernia repair (LVHR) in liver transplant recipients.

Medicare Reimbursement in Colorectal Surgery: A Growing Problem.

Background: Medicare reimbursement rates have decreased across various specialties but have not yet been studied in colorectal surgery.

Objective: This study aimed to analyze Medicare reimbursement trends in colorectal surgery.

Design: Observational study.

Capturing the often-elusive diagnosis of idiopathic myointimal hyperplasia of mesenteric veins.

Only 50 cases of idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV) have been reported since 1991 when it was first described. This rare etiology for chronic colonic ischemia is often debilitating to the patient's quality of life, and no effective medical treatment is available. IMHMV is frequently confused with inflammatory bowel disease because the most common presenting symptoms include abdominal pain, diarrhea, and hematochezia.

Differential Morphological, Structural and Biological Characteristics of Cysts in Species in Korea.

Morphological (cyst shape, color, and sizes [length (L), maximum width (W), volume and "a" (L/W)]), structural (vulvar cone slope angle [VCSA], surface wrinkle [VCSW], cyst wall thickness, composition, and texture) and biological characteristics (fecundity, hatching, and emergence [number of second-stage juveniles (J2) from a cyst]) in preceding (Hg), currently-recorded (Hs) and (Ht) were examined by microscopy. Cysts were lemon-shaped, indicating the genus is except for Hs that formed frequently globular cysts with significantly flatter VCSA (102.2°) with smooth VCSW than Hg (50.

Exploring the Effect of Post-mastectomy complications on 5-year survival.

Background: Ramifications of postoperative complications on long-term survival after mastectomy are uncertain.

Methods: Overall complications (Clavien-Dindo Grades I-IIIB) and wound complications were analyzed using the Kaplan-Meier method for impact on 5-year overall (OS) and disease-free survival (DFS).

Results: A total of 378 patients underwent mastectomy alone (157, 41%) or mastectomy with reconstruction (221, 59%) for Stage I-III disease with a median follow-up of 5 years.

Opiate Pain Medication Consumption in Cigarette Smokers following Total Hip Arthroplasty.

 The purpose of the present study was to assess perception of pain and pain management in smokers versus nonsmokers who received a total hip arthroplasty (THA).  Patients who underwent THA from 2010 to 2016 were propensity score matched 1:1 based on race, body mass index, age, and sex. This yielded 124 smokers and 124 nonsmokers.

Clostridium difficile infection in the USA: incidence and associated factors in revision total knee arthroplasty patients.

Introduction: Revision total knee arthroplasty (TKA) procedures performed secondary to periprosthetic joint infection (PJI) are associated with significant morbidity and mortality. These poor outcomes may be further complicated by postoperative infection requiring antibiotics. However, antibiotic overuse may suppress patients' bacterial flora, leading to Clostridium difficile infection (CDI).
