A diastereospecific synthesis of vicinally substituted 2-oxazolidinones from α,β-unsaturated lactams using m-chloroperoxybenzoic acid is reported. Several highly substituted 2-oxazolidinones were obtained in 19-46% yields in a one-pot reaction with complete control over the relative stereochemistry. The proposed reaction sequence consists of a Baeyer-Villiger oxidation, an epoxidation, and a conce

Caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), coronavirus disease 2019 (COVID-19) primarily manifests as respiratory dysfunction. However, emerging evidence suggests SARS-CoV-2 can invade the brain, leading to cognitive impairment (CI). It may spread to other brain regions through transsynaptic neurons, including the olfactory, optic, and vagus nerves. Moreover, it may in

ObjectiveTo provide the most up-to-date data on the burden of malignant mesothelioma (MM) and the projections through 2029 in China.MethodsData on patients diagnosed with MM from China during 1990-2019 were obtained from the Global Burden of Disease (GBD) 2019 database, including annual cases and deaths data and age-standardized rates of incidence, mortality, and disability-adjusted life-years (DA

Determining the child’s best interests in a hospital setting will ideally involve the combined views of children, parents, and healthcare professionals. However, few studies have explored parents’ experiences of their child’s best interests when they engage with the healthcare system. Therefore, this study aimed to explore parents’ experiences of their child’s best interests during hospitalisation

The bone marrow (BM) niche is a complex cellular, molecular, and physical microenvironment capable of homing and supporting hematopoiesis. It is characterized by its ability both maintain and to drive hematopoietic stem and progenitor cells (HSPCs) self-renewal and differentiation which ultimately generate all blood cell types. However, how the niche elements interact in a human context remains la

Background: Growing evidence indicates that young migrants are particularly vulnerable to sexual violence, however most research has focused on instances of sexual violence occurring in conflict zones and during transit. Much less attention has been given to the vulnerabilities to and experiences of sexual violence among young migrants in Europe.Objectives: To understand the scientific evidence re

Backround: We wanted to characterize conditional survival in prostate cancer (PC) in Sweden around and after 2005 when the vast increase in incidence due to the opportunistic testing for prostate specific antigen (PSA) culminated. We hypothesize that analyzing survival data during that time period may help interpret survival trends. We focus on stage-specific analysis using conditional survival in

Background: Sexual violence is widespread in war-torn North Kivu province in the Democratic Republic of the Congo (DRC). Timely access to care is crucial for the healing and wellbeing of survivors of sexual violence, but is problematic due to a variety of barriers. Through a better understanding of care-seeking behaviours and factors influencing timely access to care, programmes can be adapted to

IMPORTANCE: For individuals without a family history of colorectal cancer (CRC), colonoscopy screening every 10 years is recommended to reduce CRC incidence and mortality. However, debate exists about whether and for how long this 10-year interval could be safely expanded.OBJECTIVE: To assess how many years after a first colonoscopy with findings negative for CRC a second colonoscopy can be perfor

Importance: Clonal hematopoiesis of indeterminate potential (CHIP) may contribute to the risk of atrial fibrillation (AF) through its association with inflammation and cardiac remodeling. Objective: To determine whether CHIP was associated with AF, inflammatory and cardiac biomarkers, and cardiac structural changes. Design, Setting, and Participants: This was a population-based, prospective cohort

Deep Eutectic Solvents (DES) are a type of emerging solvent that are gaining in popularity for their versatile and adjustable properties, and components that can be safe, biodegradable and sustainably sourced. Here we investigate the interactions that give rise to their unique properties.The first paper looks at the question of how chirality in a component effects the DES structure. Many DES compo

INTRODUCTION: General Movement assessment (GMA) is considered the golden standard for early identification of infants with a high risk of developing cerebral palsy (CP). The aim of this study was to explore parents' lived experience of early risk assessment for CP using a mobile application for home video recording after discharge from hospital stay in the newborn period.METHODS: An inductive qual

Topological superconductors are appealing building blocks for robust and reliable quantum information processing. Most platforms for engineering topological superconductivity rely on a combination of superconductors, materials with intrinsic strong spin-orbit coupling, and external magnetic fields, detrimental for superconductivity. We propose a setup where a conventional Josephson junction is lin

Data regarding excretion of SARS-CoV-2 in semen are inconclusive and counseling regarding risk of sexual transmission is still challenging. Our knowledge on the effect of upper respiratory tract infections (URTI) on male reproductive system is also scarce. Apart from negative effect of fever on spermatogenesis virtually no study has been able to compare reproductive parameters in men with COVID-19

BackgroundIndividuals with wrist osteoarthritis (OA) can suffer from pain, muscular weakness, and impaired motion of the wrist, which can reduce the quality of life. While there is strong evidence that all patients with OA should receive first-line treatment with education and exercises, this approach has not yet been proposed for individuals with wrist OA. Therefore, this trial aimed to evaluate

Background Breathlessness and fatigue are common symptoms in older people. We aimed to evaluate how different breathlessness dimensions (overall intensity, unpleasantness, sensory descriptors, emotional responses) were associated with fatigue in elderly men. Methods This was a cross-sectional analysis of the population-based VAScular disease and Chronic Obstructive Lung Disease (VASCOL) study of 7
