Exchange bias coupling and bipolar resistive switching at room temperature on GaSb/Mn multilayers for resistive memories applications.

This work present structural, morphological, magnetic, and electrical properties of GaSb/Mn multilayer deposited via DC magnetron sputtering at room temperature and at 423 K. The samples are characterized by forming layers of 3, 6 and 12 periods of the GaSb/Mn structure. Through XRD patterns, it was possible to stablish the formation of GaSb, MnGa, and MnSb phases.

Higher Complication Rates for Total versus Partial Thyroidectomy in the Pediatric Population.

Introduction: This study aims to analyze the relative risks for total thyroidectomies by comparing complication rates for total versus partial thyroidectomy in the pediatric population.

Methods: We queried the Kids' Inpatient Database (KID) 1997-2012 for all cases of total (n = 3253) or partial (n = 2380) thyroidectomy. We then designed a propensity score matching model and compared total versus partial thyroidectomy based on surgical complications and outcomes.

Long-Term Outcomes after Adolescent Bariatric Surgery.

Background: Metabolic and bariatric surgery (MBS) is a safe and effective treatment option for adolescents with severe obesity, but no long-term studies are available with more than10 years of follow-up data to document sustained improved outcomes.

Methods: A total of 96 patients who completed MBS at 21 years of age or younger in a tertiary academic center 2002 to 2010 were contacted for a telehealth visit. Body weight, comorbidity status, social/physical function status, and long-term complications were evaluated 10 to 18 years after surgery.

Radical Resection of Pediatric Fibrosarcoma Is Not Associated With Survival Benefit: A Nationwide Database Analysis.

Introduction: Fibrosarcoma is one of the most common nonrhabdomyosarcoma soft tissue sarcomas in the pediatric population. Surgical resection is the cornerstone of treatment; however, optimal factors regarding the extent of fibrosarcoma resection in localized versus regional disease is poorly understood.

Methods: The Surveillance, Epidemiology, and End Results database was queried for patients who are 19 y old or younger with a diagnosis of fibrosarcoma from 1975 to 2016.

Nationwide outcomes of incidental appendectomy during cholecystectomy versus cholecystectomy alone in children: a propensity score-matched analysis.

Background: The utility of incidental appendectomy, appendectomy during another index surgery in the absence of appendicitis, has not been evaluated in the pediatric population during cholecystectomy. This study sought to compare nationwide outcomes after cholecystectomy with incidental appendectomy in children.

Methods: Patients ≤ 18 years old who underwent cholecystectomy from 2010-2014 were identified from the Nationwide Readmissions Database.

Risk factors associated with recent opioid-related hospitalizations in children: a nationwide analysis.

Purpose: Identifying at-risk children can provide a crucial opportunity for preventative measures to avoid opioid addiction. This study sought to determine at-risk pediatric patients that were previously hospitalized due to other causes prior to their opioid-related admission.

Methods: The Nationwide Readmissions Database (2010-2014) was queried for children 1-18 years old with an opioid-related hospitalization.

E-Selectin-Overexpressing Mesenchymal Stem Cell Therapy Confers Improved Reperfusion, Repair, and Regeneration in a Murine Critical Limb Ischemia Model.

Aims: Novel cell-based therapeutic angiogenic treatments for patients with critical limb ischemia may afford limb salvage. Mesenchymal stem cells (MSCs) do not overexpress E-selectin; however, we have previously demonstrated the cell-adhesion molecule's vital role in angiogenesis and wound healing. Thus, we created a viral vector to overexpress E-selectin on MSCs to increase their therapeutic profile.

National burden of pediatric abusive injuries: patterns vary by age.

Purpose: Child abuse is often unrecognized by healthcare practitioners. This study sought to characterize pediatric abuse injury patterns and associated mortality rates in a nationwide cohort.

Methods: The Kids' Inpatient Database (1997-2012) was queried for patients < 18 years old with a diagnosis of child abuse (utilizing ICD-9 codes for abusive head trauma [AHT], neglect, physical, emotional, sexual, and other abuse).

Ovarian Preservation and Recurrent Torsion in Children: Both Less Common Than We Thought.

Purpose: Surgical management of pediatric ovarian torsion includes total oophorectomy (TO) or ovarian preservation surgery (OPS). This study sought to identify factors contributing to surgical management and readmission outcomes for ovarian torsion.

Methods: The Nationwide Readmission Database from 2010-2014 was used to identify patients < 18 years admitted with ovarian torsion.

Gangrene, revascularization, and limb function improved with E-selectin/adeno-associated virus gene therapy.

Objective: Novel therapeutic angiogenic concepts for critical limb ischemia are still needed for limb salvage. E-selectin, a cell-adhesion molecule, is vital for recruitment of the stem/progenitor cells necessary for neovascularization in ischemic tissues. We hypothesized that priming ischemic limb tissue with E-selectin/adeno-associated virus (AAV) gene therapy, in a murine hindlimb ischemia and gangrene model, would increase therapeutic angiogenesis and improve gangrene.

A retrospective comparison of outcomes for open laparoscopic surgical techniques in pediatric ulcerative colitis.

Background: Ulcerative colitis (UC) is an aggressive disease in the pediatric population and a cause of significant, lifelong morbidity. The aim of this study is to compare surgical complications in pediatric patients undergoing laparoscopic open surgical treatment for UC.

Methods: We queried the Kids' Inpatient Database (KID) for all cases of UC undergoing surgical treatment in 2009 and 2012.

Prophylactic colectomy for children with familial adenomatous polyposis: resource utilization and outcomes for open and laparoscopic surgery.

Background: Laparoscopic approach for the surgical management of familial adenomatous polyposis (FAP) has become increasingly common for pediatric patients. The purpose of this study was to compare short-term outcomes and resource utilization between open and laparoscopic surgery for prophylactic colectomy in children with FAP.

Methods: The Kids' Inpatient Database (2009 and 2012) was analyzed for children (age ≤20 years) with FAP that underwent prophylactic total colectomy or proctocolectomy.

Complications while awaiting elective inguinal hernia repair in infants: Not as common as you thought.

Background: The dogma of early inguinal hernia repair in infants, especially those born prematurely, has dominated clinical practice owing to reports of a high frequency of incarceration and significant complications associated with untreated inguinal hernias. We aim to evaluate the frequency of complications after discharge with delayed surgery for inguinal hernia repair.

Methods: The Nationwide Readmissions Database (2010-2014) was queried to identify infants diagnosed with inguinal hernia.

Background: The purpose of this study was to identify the pattern of injuries that relates to abuse and neglect in children with burn injuries.

Methods: The Nationwide Readmissions Database for 2010-2014 was queried for all patients aged less than 18 y admitted with burn injuries. The primary outcome was child maltreatment identified at the index admission.

Drivers of Hospital Readmission and Early Liver Transplant after Kasai Portoenterostomy.

Background: Kasai portoenterostomy (KPE) remains the first-line operation for patients with biliary atresia (BA), but ultimately fails in up to 60% of cases. This study sought to identify factors contributing to hospital readmission and early liver transplant.

Methods: The Nationwide Readmissions Database from 2010 to 2014 was used to identify patients with BA who underwent KPE on index admission.

Protocol-Driven Surgical Care of Necrotizing Enterocolitis and Spontaneous Intestinal Perforation.

Background: There is no clear consensus on the optimal operative management of premature infants with surgical necrotizing enterocolitis (sNEC) or spontaneous intestinal perforation (SIP); thus, a protocol was developed to guide surgical decision making regarding initial peritoneal drainage (PD) versus initial laparotomy (LAP). We sought to evaluate outcomes after implementation of the protocol.

Methods: Pre-post study including multiple urban hospitals.

Hidden Readmissions after Carotid Endarterectomy and Stenting.

Background: Historically, carotid procedures incur a readmission rate of approximately 6%; however, these studies are not nationally representative and are limited to tracking only the index hospitals. We sought to evaluate a nationally representative database for readmission rates (including different hospitals) after both carotid endarterectomy (CEA) and carotid artery stenting (CAS) and determine risk factors for poor outcomes including postoperative mortality and myocardial infarction.

Methods: This study was a retrospective analysis utilizing the 2010-2014 Nationwide Readmissions Database to query patients aged >18 years undergoing CEA or CAS.

Open Versus Laparoscopic Right Hemicolectomies in Pediatric Patients with Crohn's Disease.

Surgery remains an important treatment modality for the management of pediatric Crohn's disease (CD). The objective of this study was to perform a comparative analysis of open right hemicolectomy (ORH) and laparoscopic right hemicolectomy (LRH) for the management of pediatric CD. The Kids' Inpatient Database (KID) was queried (2009-2012) for ICD-9 procedure codes for ORH (45.

Incidence of recurrent intussusception in young children: A nationwide readmissions analysis.

Background/purpose: Recurrent intussusception following successful nonoperative reduction has previously been reported with a frequency of 8%-12% based on data from individual institutions. Meanwhile, the timing of discharge after successful reduction continues to be debated. Here, we evaluate readmissions for recurrent intussusception in young children using a large-scale national database.

Photonic effects in natural nanostructures on Morpho cypris and Greta oto butterfly wings.

Photonic crystals are some of the more spectacular realizations that periodic arrays can change the behavior of electromagnetic waves. In nature, so-called structural colors appear in insects and even plants. Some species create beautiful color patterns as part of biological behavior such as reproduction or defense mechanisms as a form of biomimetics.
