Simultaneous determination of folate and methotrexate metabolites in serum by LC-MS/MS during high-dose methotrexate therapy

High-dose methotrexate (HDMTX) is a central component in the treatment of acute lymphoblastic leukemia, osteosarcoma, and some lymphomas and brain tumors. MTX is given at lethal doses and then is followed by rescue treatment with folinic acid (FA). Despite FA rescue, many patients suffer severe toxicity. The pharmacokinetics of FA rescue have not been sufficiently studied. However, optimization of

Resonant X-ray photo-oxidation of light-harvesting iron (II/III) N-heterocyclic carbene complexes

Two photoactive iron N-heterocyclic carbene complexes [FeII(btz)2(bpy)]2+ and [FeIII(btz)3]3+, where btz is 3,3’-dimethyl-1,1’-bis(p-tolyl)-4,4’-bis(1,2,3-triazol-5-ylidene) and bpy is 2,2’-bipyridine, have been investigated by Resonant Photoelectron Spectroscopy (RPES). Tuning the incident X-ray photon energy to match core-valence excitations provides a site specific probe of the electronic struc

Social capital, the miniaturization of community, traditionalism and mortality : A population-based prospective cohort study in southern Sweden

Objectives: To investigate associations between social capital, miniaturization of community and traditionalism and all-cause, cardiovascular (CVD), cancer and other causes mortality. Study design: Prospective cohort study. Methods: The 2008 public health survey in Scania in the southernmost part of Sweden was conducted with a postal questionnaire posted to a stratified random sample aged 18–80. T

The role of microstructural characteristics of additively manufactured Alloy 718 on tool wear in machining

This study aims to provide a fundamental understanding of the role of microstructural characteristics influencing tool wear when machining Alloy 718 fabricated using Powder Bed Fusion (PBF). The effects of preferred crystallographic orientation (texture), shape and distribution of grains, local misorientation, type and amount of precipitates as well as the type, size and amount of abrasive carbide

Osteopontin and malaria : no direct effect on parasite growth, but correlation with P. falciparum-specific B cells and BAFF in a malaria endemic area

Background: The dysregulation of B cell activation is prevalent during naturally acquired immunity against malaria. Osteopontin (OPN), a protein produced by various cells including B cells, is a phosphorylated glycoprotein that participates in immune regulation and has been suggested to be involved in the immune response against malaria. Here we studied the longitudinal concentrations of OPN in in

What motivates informal carers to be actively involved in research, and what obstacles to involvement do they perceive?

Background: Due to demographic changes and a strained public sector operating in many countries globally, informal care is increasing. Currently, at least 1.3 million adults in Sweden regularly provide help, support and/or care to a family member/significant other. With no sign of an imminent decrease in their caring activities, it is important that informal carers are considered as a key stakehol

Naprapathy versus orthopaedic standard care for common musculoskeletal disorders : an 8-year follow-up of a pragmatic randomized controlled trial in Sweden

Background: Musculoskeletal pain is among the most common reasons for seeking care, specialist competence for its treatment in primary care limited and waiting lists for orthopaedics often amongst the longest. Many referrals to orthopaedics do not concern disorders that benefit from surgery. Manual therapy is effective, yet not integrated in national health care systems, and there is a lack of res

Translation, adaptation and testing of an emergency care satisfaction scale in Swedish pediatric emergency departments

Background: Pediatric healthcare today shows a rising demand for research focusing on children’s perspectives on and consumer satisfaction with the nursing care they receive. Therefore, the purpose of this study was to translate and adapt the Consumer Emergency Care Satisfaction Scale (CECSS), a paper-based, self-administered 19-item questionnaire originally developed in the United States and targ

Palivizumab for preventing severe respiratory syncytial virus (RSV) infection in children

Background: Respiratory viruses are the leading cause of lower respiratory tract infection (LRTI) and hospitalisation in infants and young children. Respiratory syncytial virus (RSV) is the main infectious agent in this population. Palivizumab is administered intramuscularly every month during five months in the first RSV season to prevent serious RSV LRTI in children. Given its high cost, it is e

Arching from function to form—important design elements of simulation exercises (Simex) in emergency response and disaster risk management

With Rasmussen’s abstraction hierarchy as starting point, the present article focuses on understanding some of the aspects guiding the development of a simulation exercise (SimEx) from a multi-faceted perspective, based on interviews and post-exercise evaluations conducted with both exercise designers and participants. The results show that, in order to achieve its overarching objective, an exerci

Reconfiguring work and organizing for post-pandemic futures

Across the world, the pandemic has made many of us rapidly change (at least temporarily) how we organize, work, and live, provoking a series of urgent questions. What is our relationship with the family, community, environment and the state? How should we structure our work? How do we value essential work and workers? How are we going to live, work, and organize differently in a post-pandemic worl

Work, reconfigured

This open issue is published against the background of a major global pandemic. The old ‘normal’ seems far away and undesirable, as a socio-ecological transformation becomes even more urgent. The contributions featured here scrutinize the current trends in the capitalist mode of production and envision the alternative organization of our societies. They examine new configurations of work, to which

Associations between off-label low-dose olanzapine or quetiapine and cardiometabolic mortality

Olanzapine and quetiapine are routinely used off-label at lower doses, though it remains unclear whether treatment is associated with mortality. Here, we examined the associations between low-dose olanzapine/quetiapine, defined as 5 mg/day of olanzapine equivalents (OE) with cardiometabolic mortality in a population-based, longitudinal cohort of individuals who sought specialized psychiatric servi

TEG-pucken: föreställningar om en framtida sjukhusvistelse

Det uppskattas att år 2050 kommer tio miljoner människor att dö av infektionersom inte kan behandlas på grund av att bakterier blivit resistenta ochdärmed gjort antibiotika ineffektiv. Denna typ av dystopier är en form avresor både bakåt och framåt i tiden, och där samhället beskrivs som någotannat än vad vi är vana vid. Tanken om en framtid utan antibiotika – enså kallad postantibiotisk era – går

Relation of Early Monomorphic Ventricular Tachycardia to Long-Term Mortality in ST-Elevation Myocardial Infarction

Early ventricular tachycardia (VT) and ventricular fibrillation (VF) are associated with increased in-hospital mortality but do not influence the long-term prognosis in ST-elevation myocardial infarction (STEMI). Recent data advocate a differential approach to the type of arrhythmia and indicate long-term mortality hazard associated with monomorphic VT. We aimed to evaluate the prognostic value of

High-resolution ex vivo analysis of the degradation and osseointegration of Mg-xGd implant screws in 3D

Biodegradable magnesium (Mg) alloys can revolutionize osteosynthesis, because they have mechanical properties similar to those of the bone, and degrade over time, avoiding the need of removal surgery. However, they are not yet routinely applied because their degradation behavior is not fully understood. In this study we have investigated and quantified the degradation and osseointegration behavior

Workplace incivility and bystanders’ helping intentions

Purpose: Using observational and experimental designs, the purpose of this study was to explore if the power relation between the offender and the victim of incivility and the level of perceived severity of the incivility were associated with bystanders’ intentions to help when witnessing workplace incivility. Design/methodology/approach: In Study 1, 160 participants completed a questionnaire wher
