Background The alpha-emitter radium-223 (Ra-223) is a bone-seeking radionuclide studied as a new treatment for patients with bone metastases from hormone-refractory prostate cancer. We aimed to study mature outcomes from a randomised, multicentre, phase II study of Ra-223. Methods Patients with hormone-refractory prostate cancer and bone pain needing external-beam radiotherapy were assigned to fou

A rheological study of mixed micelles formed by PEO-PPO-PEO triblock copolymer P123 and nonionic surfactant C12EO6 in aqueous solutions has been carried out with the purpose of investigating the time dependence of a shape transition of the mixed micelles and characterizing the shape before and after the transition. The rheology results presented in this report give clear evidence that the P123-C12

Purpose: This study aimed to assess the accuracy of patient-specific absorbed dose calculations for tumours and organs at risk in radiopharmaceutical therapy planning, utilizing hybrid planar-SPECT/CT imaging. Methods: Three Monte Carlo (MC) simulated digital patient phantoms were created, with time-activity data for mIBG labelled to I-123 (LEHR and ME collimators) and I-131 (HE collimator). The s

BACKGROUND: Minimally invasive surgery is rapidly expanding globally, yet there is insufficient knowledge of how to scale this technology safely and equitably across diverse health systems. We aimed to identify health-system factors associated with safe implementation of minimally invasive surgery globally, using minimally invasive cholecystectomy as a tracer procedure.METHODS: We conducted a mult

BACKGROUND AND OBJECTIVES: Multiple system atrophy (MSA) is a neurodegenerative disorder characterized by 3 core symptom complexes: parkinsonism, cerebellar syndrome, and dysautonomia. Recent Movement Disorder Society (MDS) criteria allow for the clinical diagnosis of MSA based solely on motor symptoms, without requiring dysautonomia. This study aimed to evaluate the frequency and disease trajecto

Despite the issue of greywater management gaining more importance around the world, espe-cially in developing countries, it still remains a challenge in non-sewered areas of South Afri-ca. For a semi-arid country, reusing greywater on a household level has great potential as an alternative water source if done properly. On a household level, the popular repurposing of greywater is for irrigation

5-Hydroxymethylfurfural (HMF) is a versatile bio-based platform chemical that can substitute fossil-derived intermediates in polymers, solvents, and fuels, thereby contributing to a fossil-free chemical industry. While first-generation feedstocks such as high-fructose corn syrup have been widely studied, their use raises concerns about competition with food supply. In contrast, second-generation r

Background: The impact of air pollution and road traffic noise on depression remains inconclusive. This study examined long-term residential exposure to air pollutants and road traffic noise in relation to dispensed antidepressant medications. Methods: A cohort study was conducted using the Swedish Malmö Diet and Cancer Study, with the outcome defined as a first dispensed antidepressant (ATC: N06A

This paper addresses the conflict between an ethics of care and instrumental concerns in caring leadership. Caring leadership has become increasingly popular in organisation and management studies, encompassing a view of leadership that emphasises that paying attention to relational concerns is a fundamental duty of managers in contemporary organisations. It emphasises leaders seeing employees not

Background Suicide is more common among males and in older age, but the understanding of sex-specific and age-specific risk indicators is limited. Objective To describe the sex-specific and age-specific prevalence of 25 suicide risk indicators in the year preceding suicide and estimate their associations with suicide. Methods Register-based population-nested case-control study in Sweden, 2009–2021

Background Human papillomavirus (HPV) is associated with an increased risk for a variety of squamous cell carcinomas in the general population. The risk for subsequent squamous cell carcinomas in blood or marrow transplantation survivors that are potentially related to HPV (cervical, oropharyngeal, vulvar, vaginal, anal, and penile cancer; HPV-related squamous cell carcinomas) remains unknown. Met

Objectives: To analyze device designs, similarities and overlaps of custom-made fenestrated arch endografts intended for mid/distal arch thoracic endovascular aortic repair. Materials and Methods: A multicenter cross-sectional study analyzing custom-made anonymized graft plans was performed. Graft plans were included from a cohort of mid/distal aortic arch repairs using custom-made fenestrated aor

BACKGROUND AND PURPOSE: To date, large studies comparing mortality and functional outcome of intracerebral hemorrhage (ICH) during oral anticoagulant (OAC), antiplatelet, and nonantithrombotic use are few and show discrepant results. METHODS: We used data on 13 291 patients with ICH registered in Riksstroke between 2012 and 2016 to compare 90-day mortality and functional outcome following OAC-rela

BACKGROUND: Opioids are still widely prescribed to long-term pain patients although they are no longer recommended for long-term treatments due to poor evidence for long-term efficacy, risks of serious side effects, and the possibility of inducing opioid hyperalgesia. In a Cochrane study from 2017, the authors identified an urgent need for more randomized controlled trials investigating the effici

Context. After more than 50 years, astronomical research still struggles to reconstruct the history of lithium enrichment in the Galaxy and to establish the relative importance of the various 7Li sources in enriching the interstellar medium (ISM) with this fragile element. Aims. To better trace the evolution of lithium in the Milky Way discs, we exploit the unique characteristics of a sample of op

BACKGROUND: Given the high heterogeneity among breast tumors, associations between common germline genetic variants and survival that may exist within specific subgroups could go undetected in an unstratified set of breast cancer patients. METHODS: We performed genome-wide association analyses within 15 subgroups of breast cancer patients based on prognostic factors, including hormone receptors, t

Background: Treatment of mentally disordered offenders (MDOs) is challenging as their behavior and clinical conditions can be traced to a complex constellation of major mental disorders, substance use and antisocial lifestyle. Finding subgroups of these offenders, which could guide treatment and risk assessment, is desirable. There are few long-term, prospective studies of risk factors for persist
