On the discovery of new elements (IUPAC/IUPAP Report) : Report of the 2017 Joint Working Group of IUPAC and IUPAP

Almost thirty years ago the criteria that are currently used to verify claims for the discovery of a new element were set down by the comprehensive work of a Transfermium Working Group, TWG, jointly established by IUPAC and IUPAP. The recent completion of the naming of the 118 elements in the first seven periods of the Periodic Table of the Elements was considered as an opportunity for a review of

Impact of baseline COPD symptom severity on the benefit from dual versus mono-bronchodilators : an analysis of the EMAX randomised controlled trial

Rationale: Symptom relief is a key treatment goal in patients with chronic obstructive pulmonary disease (COPD). However, there are limited data available on the response to bronchodilator therapy in patients at low risk of exacerbations with different levels of symptom severity. This study compared treatment responses in patients with a range of symptom severities as indicated by baseline COPD as

Similar early mortality risk after cemented compared with cementless total hip arthroplasty for primary osteoarthritis : data from 188,606 surgeries in the Nordic Arthroplasty Register Association database

Background and purpose — Current literature indicates no difference in 90-day mortality after cemented compared with cementless total hip arthroplasty (THA). However, previous studies are hampered by potential selection bias and suboptimal adjustment for comorbidity confounding. Therefore, we examined the comorbidity-adjusted mortality up to 90 days after cemented compared with cementless THA perf

The Effectiveness of Evacuation Alarms in Multi-Hazard Environments

The aim of this thesis is to investigate the effectiveness of using specific alarms for each hazardversus the effectiveness of using a single alarm for all hazards in multi-hazard facilities. Theresearch was conducted by disseminating online questionnaires containing audio files of differentalarms to occupants of multi-hazards facilities and conducting interviews with safety expertsworking at mult

Energy inequality as a risk in socio-technical energy transitions : The Swedish case of individual metering and billing of energy for heating

Improved energy efficiency in the housing stock is an important undertaking in the energy transition but is associated with both opportunities and risks. While there are possibilities to reduce energy inequalities in the housing stock, inequalities also risk being aggravated as actions for energy efficiency usually aim at the least energy efficient—and thus sometimes the least privileged—parts of Improved energy efficiency in the housing stock is an important undertaking in the energy transition but is associated with both opportunities and risks. While there are possibilities to reduce energy inequalities in the housing stock, inequalities also risk being aggravated as actions for energy efficiency usually aim at the least energy efficient—and thus sometimes the least privileged—parts of

Association between fixation type and revision risk in total knee arthroplasty patients aged 65 years and older : a cohort study of 265,877 patients from the Nordic Arthroplasty Register Association 2000–2016

Background and purpose — The population of the Nordic countries is aging and the number of elderly patients undergoing total knee arthroplasty (TKA) is also expected to increase. Reliable fixation methods are essential to avoid revisions. We compared the survival of different TKA fixation concepts with cemented fixation as the gold standard. Patients and methods — We used data from the Nordic Arth

QCD challenges from pp to A–A collisions

This paper is a write-up of the ideas that were presented, developed and discussed at the third International Workshop on QCD Challenges from pp to A–A, which took place in August 2019 in Lund, Sweden (Workshop link: https://indico.lucas.lu.se/event/1214/). The goal of the workshop was to focus on some of the open questions in the field and try to come up with concrete suggestions for how to make

Precipitating factors of heart failure decompensation, short-term morbidity and mortality in patients attended in primary care

Objective: To evaluate the precipitating factors for heart failure decompensation in primary care and associations with short-term prognosis. Design Prospective cohort study with a 30-d follow-up from an index consultation. Regression models to determine independent factors associated with hospitalisation or death. Setting: Primary care in ten European countries. Patients Patients with diagnosis o

A probabilistic-deterministic analysis of human health risk related to the exposure to potentially toxic elements in groundwater of Urmia coastal aquifer (NW of Iran) with a special focus on arsenic speciation and temporal variation

The human exposure to groundwater contamination with toxic elements is a worldwide concern. In this study, multivariate statistics coupled with probabilistic and deterministic risk estimation approaches were applied to 173 groundwater samples of Urmia aquifer (UA) to evaluate human health risks in relation to the consumption of groundwater contaminated with toxic elements. The concentrations of al

Molecular species delimitation of larks (Aves : Alaudidae), and integrative taxonomy of the genus calandrella, with the description of a range-restricted african relic taxon

Larks constitute an avian family of exceptional cryptic diversity and striking examples of convergent evolution. Therefore, traditional morphology-based taxonomy has recurrently failed to reflect evolutionary relationships. While taxonomy ideally should integrate morphology, vocalizations, behaviour, ecology, and genetics, this can be challenging for groups that span several continents including a

A reference map of potential determinants for the human serum metabolome

The serum metabolome contains a plethora of biomarkers and causative agents of various diseases, some of which are endogenously produced and some that have been taken up from the environment1. The origins of specific compounds are known, including metabolites that are highly heritable2,3, or those that are influenced by the gut microbiome4, by lifestyle choices such as smoking5, or by diet6. Howev

Association of Circulating Monocyte Chemoattractant Protein-1 Levels with Cardiovascular Mortality : A Meta-analysis of Population-Based Studies

Importance: Human genetics and studies in experimental models support a key role of monocyte-chemoattractant protein-1 (MCP-1) in atherosclerosis. Yet, the associations of circulating MCP-1 levels with risk of coronary heart disease and cardiovascular death in the general population remain largely unexplored. Objective: To explore whether circulating levels of MCP-1 are associated with risk of inc

The Gaia -ESO Survey : Spectroscopic-asteroseismic analysis of K2 stars in Gaia -ESO

Context. The extensive stellar spectroscopic datasets that are available for studies in Galactic Archeaology thanks to, for example, the Gaia-ESO Survey, now benefit from having a significant number of targets that overlap with asteroseismology projects such as Kepler, K2, and CoRoT. Combining the measurements from spectroscopy and asteroseismology allows us to attain greater accuracy with regard

Increased Plasma Soluble Interleukin-2 Receptor Alpha Levels in Patients With Long-Term Type 1 Diabetes With Vascular Complications Associated With IL2RA and PTPN2 Gene Polymorphisms

Type 1 diabetes (T1D) is largely considered an autoimmune disease leading to the destruction of insulin-producing pancreatic β cells. Further, patients with T1D have 3–4-fold increased risk of developing micro- and macrovascular complications. However, the contribution of immune-related factors contributing to these diabetes complications are poorly understood. Individuals with long-term T1D who d

COVID-19 during Pregnancy and Postpartum:: I) Pathobiology of Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) at Maternal-Fetal Interface

Coronavirus Disease 2019 (COVID-19) triggered by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection has been declared a pandemic by the World Health Organization (WHO) on March 11, 2020. Oxidative stress and its related metabolic syndromes are potential risk factors in the susceptibility to, and severity of COVID-19. In concert with the earliest reports of COVID-19, obstetricia

Pronounced Plastic and Evolutionary Responses to Unpredictable Thermal Fluctuations in Drosophila simulans

Organisms are exposed to temperatures that vary, for example on diurnal and seasonal time scales. Thus, the ability to behaviorally and/or physiologically respond to variation in temperatures is a fundamental requirement for long-term persistence. Studies on thermal biology in ectotherms are typically performed under constant laboratory conditions, which differ markedly from the variation in tempe

Gender differences in self-care for common colds by primary care patients : a European multicenter survey on the prevalence and patterns of practices (the COCO study)

Although generally harmless, the common cold disturbs the lives of billions yearly. It is frequently treated by self-care, yet little is known about the effect gender may have on self-care. Our study set out to discover whether self-care for common colds differs by gender. We also wanted to test the ‘Man cold’ belief: that men ‘break down’ when they have a cold and suffer more than women when they

Risk of digestive cancers in a cohort of 69 460 five-year survivors of childhood cancer in Europe: The PanCareSurFup study

Background: Survivors of childhood cancer are at risk of subsequent primary neoplasms (SPNs), but the risk of developing specific digestive SPNs beyond age 40 years remains uncertain. We investigated risks of specific digestive SPNs within the largest available cohort worldwide. Methods: The PanCareSurFup cohort includes 69 460 five-year survivors of childhood cancer from 12 countries in Europe. R
