Relevance of breast cancer hormone receptors and other factors to the efficacy of adjuvant tamoxifen : patient-level meta-analysis of randomised trials

BACKGROUND: As trials of 5 years of tamoxifen in early breast cancer mature, the relevance of hormone receptor measurements (and other patient characteristics) to long-term outcome can be assessed increasingly reliably. We report updated meta-analyses of the trials of 5 years of adjuvant tamoxifen.METHODS: We undertook a collaborative meta-analysis of individual patient data from 20 trials (n=21,4

Damage Analysis of Reactive Ion and Quasi-Atomic Layer Etched Silicon

Atomic layer etching (ALE) is a cyclic technique based on self-limiting processes, such as reactive gas adsorption and material removal by low-energy ion bombardment 1,2. In a typical ALE process Ar+ ions with energies of 20-60 eV are used to desorb the reaction products, e.g. SiClx for the Si ALE. Compared to a corresponding continuous reactive ion etching (RIE), where the ion energies often exce

In situ characterization of stresses, deformation and fracture of thin films using transmission X-ray nanodiffraction microscopy

The use of hard X-ray transmission nano- and microdiffraction to perform in situ stress and strain measurements during deformation has recently been demonstrated and used to investigate many thin film systems. Here a newly commissioned sample environment based on a commercially available nanoindenter is presented, which is available at the NanoMAX beamline at the MAX IV synchrotron. Using X-ray na

Impaired oligodendrogenesis in the white matter of aged mice following diffuse traumatic brain injury

Senescence is a negative prognostic factor for outcome and recovery following traumatic brain injury (TBI). TBI-induced white matter injury may be partially due to oligodendrocyte demise. We hypothesized that the regenerative capacity of oligodendrocyte precursor cells (OPCs) declines with age. To test this hypothesis, the regenerative capability of OPCs in young [(10 weeks ±2 (SD)] and aged [(62

Photonic sensors reflect variation in insect abundance and diversity across habitats

To mitigate ongoing insect biodiversity declines, there is a need for efficient yet accurate monitoring methods. The use of traditional catch-based survey methods is constrained both by costs and need for expertise for manual taxonomic identification. Emerging methods, such as eDNA and robotic sorting, have the potential to reduce workload but still require resource-intensive sample collection in

Rapid acquisition of digital fingerprints of Ti-6Al-4V macrotexture from machining force measurement data

Titanium alloys display anisotropic deformation properties due to the hexagonal close-packed (hcp) crystal structure of the α-phase. When subjected to localised deformation during machining, this behaviour influences fluctuations in the cutting force response of the material as the tool encounters grains of different orientations. In this research, cutting force signals acquired during face turnin

Operating Theater Nurses’ Main Concerns During Organ Procurement Procedures : A Grounded Theory Study

The purpose of this study was to explore the experiences of perioperative nurses in Sweden (ie, operating theater nurses) associated with caring for a donor patient during organ procurement procedures. We sought to determine the nurses’ main concerns and how they dealt with them. Using constructivist grounded theory methodology, our participant sample included 10 nurses, one of whom self-identifie

Overview of the randomized trials of radiotherapy in ductal carcinoma in situ of the breast

Individual patient data were available for all four of the randomized trials that began before 1995, and that compared adjuvant radiotherapy vs no radiotherapy following breast-conserving surgery for ductal carcinoma in situ (DCIS). A total of 3729 women were eligible for analysis. Radiotherapy reduced the absolute 10-year risk of any ipsilateral breast event (ie, either recurrent DCIS or invasive

Proximity and Inequality in Academia

When mattering is defined as being able to disseminate ideas on a global scale, not all universities and researchers matter equally. Along with many other factors, geographical location can be a source of inequality in the science system, which is characterized by a persistent core–semi-periphery–periphery structure. Collaboration between high-, middle-, and low-income countries, frequently enable

Origin and the evolution of diatoms through the integration of paleontology and phylogenetics

Diatoms, the prominent photosynthetic eucaryotes, have inhabited the world’s oceans for at least the past 120 Ma since their first appearance in the Lower Cretaceous. There are also records of older diatoms, from the Jurassic dating to ca. 172 Ma and ca. 165 Ma, however these are poorly documented. The predicted origin time of diatoms using evolutionary relationships (molecular phylogenetics) yiel

Adjuvant chemotherapy in oestrogen-receptor-poor breast cancer : patient-level meta-analysis of randomised trials

BACKGROUND: The long-term effects of adjuvant polychemotherapy regimens in oestrogen-receptor-poor (ER-poor) breast cancer, and the extent to which these effects are modified by age or tamoxifen use, can be assessed by an updated meta-analysis of individual patient data from randomised trials.METHODS: Collaborative meta-analyses of individual patient data for about 6000 women with ER-poor breast c

Soil, fertilizer and plant density : Exploring the influence of environmental factors to stable nitrogen and carbon isotope composition in cereal grain

Stable isotope analysis (N and C) of fossil cereal grains is regularly explored as a means of obtaining insights to past crop growing conditions and agricultural practices. In this study, we assessed how several growth conditions can affect δ15N and δ13C values of modern cereal grain with the aim to help understand isotopic values from ancient cereal remains. We investigated the impact of fertiliz

Capacity development in international aid : A contribution to theory and practice

Although capacity development has been a key aspect of global aid policy for decades, success is limited. Capacity development is defined as a process, based on a partnership, to develop capacity to achieve a goal. The purpose of this thesis is to increase our understanding of why capacity development does not work as intended, and to inform the discussion on addressing the challenges. Two researc

Life story templates in dementia care : Ambiguous direction and purpose

Background: The use of life stories in dementia care has been described as a way of seeing every person as an individual, looking beyond their dementia. Life stories have become synonymous with high-quality care, while in Sweden their mere existence in dementia care settings is taken to indicate quality in national comparisons. Such life stories are often standardised, generated by a family member

The frontlines of contested urbanism : Mega-projects and mega-resistances in Dharavi

Currently, there appears to be an unhealthy disjunction between grand expectations and acknowledged reality in the face of urban transformations underway throughout the world. Drawing on the "right to the city" discourses, adopting a Lefebvrian approach to the production of space, and a critical regionalist approach to housing and the built environment, the article explores the conceptual analytic

Are green cities healthy and equitable? Unpacking the relationship between health, green space and gentrification

While access and exposure to green spaces has been shown to be beneficial for the health of urban residents, interventions focused on augmenting such access may also catalyse gentrification processes, also known as green gentrification. Drawing from the fields of public health, urban planning and environmental justice, we argue that public health and epidemiology researchers should rely on a more

The Swedish version of the Moorong Self-Efficacy Scale (s-MSES) – translation process and psychometric properties in a community setting

Study design: Psychometric study. Objectives: To i) describe the translation process and ii) explore the data completeness, targeting, reliability and aspects of validity of the Swedish version of Moorong Self-Efficacy Scale (s-MSES). Settings: Community rehabilitation program. Methods: Ninety-two program participants and 42 peer mentors with spinal cord injury (SCI) in Active Rehabilitation train

The right to the unhealthy deprived city : An exploration into the impacts of state-led redevelopment projects on the determinants of mental health

Research shows mental health is impacted by poor-quality physical and social-environmental conditions. Subsequently state-led redevelopment/regeneration schemes focus on improving the physical environment, to provide better social-environmental conditions, addressing spatial and socioeconomic inequities thus improving residents' health. However, recent research suggests that redevelopment/regenera

Shared decision-making before prostate cancer screening decisions

Decisions around prostate-specific antigen screening require a patient-centred approach, considering the benefits and risks of potential harm. Using shared decision-making (SDM) can improve men’s knowledge and reduce decisional conflict. SDM is supported by evidence, but can be difficult to implement in clinical settings. An inclusive definition of SDM was used in order to determine the prevalence
