What The Study Did: The association of the COVID-19 pandemic with general surgical residents' operative experience by postgraduate year and case type is examined in this study.

What The Study Did: This simulation study estimates key populations and performance indicators along the COVID exposure notification chain of the SwissCOVID digital contact tracing app last year in Zurich, Switzerland.

What The Study Did: Changes in the demographic characteristics and clinical outcomes of pediatric emergency department visits for mental health conditions during the COVID-19 pandemic are described in this study.

Research presented today at the AATS 101st Annual Meeting, shows that the six year Integrated Cardiothoracic (CT I-6) residency continues to be the most challenging to match, while the pool of applicants has become more diverse. The study, which aimed to identify applicant characteristics associated with a successful match, used data from the National Residency Matching Program (NRMP), Electronic Residency Application Service (ERAS), and Association of American Medical Colleges (AAMC) for Thoracic Surgery, and other sources.

Effectively and safely protecting against disease--this is what makes vaccines a vital and successful public health tool that saves lives and safeguards health and well-being. Looking at immunisation programmes' successes and remaining challenges, this week's issue of Eurosurveillance is published on the occasion of European Immunization Week (EIW) 2021.

A new gene-editing technique can be used to correct mutations in muscle stem cells, paving the way for the first potential cell therapy for genetic muscle disorders. The ECRC team led by Professor Simone Spuler have published their findings in the journal JCI Insight.

Researchers in the Nanoscience Center of University of Jyväskylä in Finland and in the Guadalajara University in Mexico developed a method that allows for simulation and visualization of magnetic-field-induced electron currents inside gold nanoparticles. The method facilitates accurate analysis of magnetic field effects inside complex nanostructures in nuclear magnetic resonance measurements and establishes quantitative criteria for aromaticity of nanoparticles. The work was published 30.4.2021 as an Open Access article in Nature Communications.

Many industrial processes emit carbon dioxide into the atmosphere. Unfortunately, however, current electrochemical separation methods are expensive and consume large amounts of power. They also require expensive and rare metals as catalysts. A study in the journal Angewandte Chemie describes a new aerogel electrocatalyst formed from an inexpensive metal alloy, which enables highly efficient electrochemical conversion of carbon dioxide. The main product is formic acid, which is a nontoxic basic chemical.

The study reports the design and preparation of erythrocyte membrane-bound nanoparticles (M@AP), for tumoral photodynamic-immunotherapy. The M@AP is formed by self-assembly of aggregation-induced emission polymer (AIEgens) (named P2-PPh3) and polyinosinic : polycytidylic (Poly(I:C)), followed by erythrocyte membrane encapsulation. The M@AP nanoparticles combines the PDT properties of the AIE-active polyelectrolyte and immunotherapy properties of Poly(I:C) to achieve synergistic activation of the immune system for anti-tumor activity.

'Feel-good films' are usually dismissed by film critics as being sentimental and without intellectual merit. But their popularity with audiences, who seek them out precisely because of their 'feel-good' qualities, tells a more favorable story. Now, for the first time, this popular movie genre has been examined scientifically.

Doctors treating babies born with Turner syndrome need to look for heart rhythm abnormalities, in addition to the usual heart problems of high blood pressure or left-sided structural heart defects, according to Meena Bolourchi, MD, assistant professor of pediatrics at Boston University School of Medicine.

Humans have significantly altered biodiversity in all climate zones of the Earth. This has been shown by a study now published in "Science". Led by Prof. Dr. Manuel Steinbauer at the University of Bayreuth, and Dr. Sandra Nogué at the University of Southampton, an international team has investigated how the flora on 27 islands in different regions has developed over the last 5,000 years. Almost everywhere, the arrival of humans has triggered a markedly accelerated change in species composition in previously pristine ecosystems.

Traditional methods in histopathology are generally limited to thin specimens and require chemical processing of the tissue to provide sufficiently high contrast for imaging, which slows the process. A recent advance in histopathology eliminates the need for chemical staining and enables high-resolution imaging of thick tissue sections. As reported in Advanced Photonics, an international research team recently demonstrated a 3D label-free quantitative phase imaging technique that uses optical diffraction tomography to obtain volumetric imaging information.

'Pokemonas' live in round amoebae, similar to Pokémon, which are caught inside balls in the popular video game.

The detection of the axion would mark a key episode in the history of science. This hypothetical particle could resolve two fundamental problems of Modern Physics at the same time: the problema of Charge and Parity in the strong interaction, and the mystery of dark matter.

Small changes of sodium in the blood reduce the amount of energy produced in the mitochondria - the power plants of our cells. This has consequences for immune cells. An international research team led by MDC scientists hasdiscovered the mechanism behind this phenomenon and published their findings in the journal Circulation.

Palmer amaranth is a hard-to-control noxious weed that can significantly reduce crop yields. It was first introduced in Minnesota in 2016 through contaminated seed mixes used for conservation plantings.

A single dose of vaccine boosts protection against SARS-CoV-2 coronavirus variants, but only in those with previous COVID-19, a study has found.

Evidence from the medical literature that contributes to adopting a new practice into clinical care is integral for surgical quality improvement. Part II of a comprehensive review of five key principles of the American College of Surgeons (ACS) Quality Verification Program demonstrates the role of data surveillance and standardized processes and systems to identify problems and improve the quality and safety of surgical patient care.

Social, economic, and demographic factors that can influence health did not affect families' acceptance of telehealth for their children's cardiac care during the COVID-19 pandemic, according to a study presented at the Pediatric Academic Society 2021 Virtual Meeting. The study, by research team members at the Nemours Children's Health System, suggests that telehealth is a feasible tool for families regardless of household income, language, or insurance type.
