Growth and martensitic transformation of ferromagnetic Co-Cr-Ga-Si epitaxial films.

During cooling, conventional martensitic transformation can only be realized from austenite to martensite. Recently, a so-called reentrant martensitic transformation attracted much interest due to an additional transformation from martensite to austenite during further cooling. Obviously, materials with this reentrant transformation will increase the number of physical effects and possible applications.

Open Versus Laparoscopic Pyloromyotomy for Pyloric Stenosis-A Systematic Review and Meta-Analysis.

Introduction: Infantile hypertrophic pyloric stenosis is treated by either open pyloromyotomy (OP) or laparoscopic pyloromyotomy (LP). The aim of this meta-analysis was to compare the open versus laparoscopic technique.

Methods: A literature search was conducted from 1990 to February 2021 using the electronic databases MEDLINE, Embase, and Cochrane Central Register of Controlled Trials.

Statistics decrypted-a comprehensive review and smartphone-assisted five-step approach for good statistical practice.

Background: Statistic scripts are often made by mathematicians and cryptic for clinicians or non-mathematician scientists. Nevertheless, almost all research projects necessitate the application of some statistical tests or at least an understanding thereof. The present review aims on giving an overview of the most common statistical terms and concepts.

Open versus laparoscopic pyloromyotomy for pyloric stenosis.

Background: Infantile hypertrophic pyloric stenosis (IHPS) is a disorder of young children (aged one year or less) and can be treated by laparoscopic (LP) or open (OP) longitudinal myotomy of the pylorus. Since the first description in 1990, LP is being performed more often worldwide.

Objectives: To compare the efficacy and safety of open versus laparoscopic pyloromyotomy for IHPS.

Is it worth to explore the contralateral side in unilateral childhood inguinal hernia?: A PRISMA-compliant meta-analysis.

Background: It is still not clear if the contralateral side should be explored in children with unilateral inguinal hernias. The primary aim of the present study was to assess the incidence of metachronous contralateral inguinal hernias (MCIHs) in the pediatric population. The second aim was to assess factors associated with increased risk of MCIH development.

Superior Magnetic Performance in FePt L1 Nanomaterials.

The discovery of the high maximum energy product of 59 MGOe for NdFeB magnets is a breakthrough in the development of permanent magnets with a tremendous impact in many fields of technology. This value is still the world record, for 40 years. This work reports on a reliable and robust route to realize nearly perfectly ordered L1 -phase FePt nanoparticles, leading to an unprecedented energy product of 80 MGOe at room temperature.

Impact of Sleep Deprivation on Surgical Laparoscopic Performance in Novices: A Computer-based Crossover Study.

Objective: The 24-hour work shifts are newly permitted to first-year surgical residents in the United States. Whether surgery novices' motor activity is affected by sleep deprivation is controversial.

Materials And Methods: This study assesses sleep deprivation effects in computer-simulated laparoscopy in 20 surgical novices following 24 hours of sleep deprivation and after resting using a virtual-reality trainer.

Chronic pain and quality of life after inguinal hernia repair using the COMI-hernia score.

Purpose: The Core Outcome Measure Index (COMI) is a brief and multidimensional, patient-orientated outcome questionnaire that assesses chronic pain and quality of life after groin hernia repair. The primary aim of this study was to prospectively assess the COMI-hernia score, over an extended period of time in a single large cohort of patients.

Methods: Two hundred and twenty-eight male patients with inguinal hernia repair were included in the present study.

Five-year Follow-up and Recurrence Rates Following Surgery for Acute and Chronic Pilonidal Disease: A Survey of 421 Cases.

Objective: The aim of the present study was to investigate the outcomes of different treatment options for acute and chronic pilonidal disease in a single large cohort of patients.

Materials And Methods: Four hundred and twenty-one consecutive patients (171 with chronic disease and 250 with acute abscess formation) who underwent surgery between 2003 and 2012 were included in the present study. Primary outcomes included symptomatic recurrence, time to wound healing, and time off from work.
