Omission of Radiotherapy in Primary Mediastinal B-Cell Lymphoma: IELSG37 Trial Results

PURPOSE The role of consolidation radiotherapy in patients with primary mediastinal B-cell lymphoma (PMBCL) is controversial. METHODS The IELSG37 trial, a randomized noninferiority study, aimed to assess whether irradiation can be omitted in patients with PMBCL with complete metabolic response (CMR) after induction immunochemotherapy. The primary end point was progression-free survival (PFS) at 30

Effect of nanoparticle concentration and surfactants on nanofluid pool boiling

Silica nanofluids are prepared with a concentration varying from 0.001 vol.% to 0.003 vol.%, and pool boiling of the nanofluids is experimentally investigated. It is found that critical heat flux and heat transfer coefficient increase by a maximum of 62.66% and 45.88% compared with deionized water. The best boiling performance is achieved with the nanofluid of 0.002 vol.%. In addition, the paper f

On the Separability of Functions and Games

We study the notion of (additive) separability of a function of several variables with respect to a hypergraph (H-graph). We prove the existence of a unique minimal H-graph with respect to which a function is separable and show that the corresponding minimal decomposition of the function can be obtained through a recursive algorithm. We then focus on (strategic form) games and propose a concept of

Anorectal malformations

Anorectal malformations (ARM) are rare congenital anomalies with an overall prevalence of 3.32 per 10,000 pregnancies. ARM describe a spectrum of anomalies of the anus and rectum ranging from a minimally displaced anal canal to a complete fusion of the anorectum, vagina and urethra with hypoplastic sphincter and pelvic floor muscle. Aberrant septation of the hindgut with anomalous cloacal membrane

AGREE II Quality Assessment of National and International Clinical Practice Guidelines on Prostate Cancer Management by the OPTIMA Consortium

Background and objective: Clinical practice guidelines for prostate cancer (PCa) are a valuable resource for everyday clinical practice. The clinical practice guidelines and recommendations produced by various societies should demonstrate a considerable level of consistency in terms of quality, regardless of the society that developed these given the common evidence base. However, to date, no stud

Male harm suppresses female fitness, affecting the dynamics of adaptation and evolutionary rescue

One of the most pressing questions we face as biologists is to understand how climate change will affect the evolutionary dynamics of natural populations and how these dynamics will in turn affect population recovery. Increasing evidence shows that sexual selection favors population viability and local adaptation. However, sexual selection can also foster sexual conflict and drive the evolution of

CoopeRIS : A framework for the simulation of reconfigurable intelligent surfaces in cooperative driving environments

Future connected vehicles will require high-performance communication technologies for advanced cooperative driving applications such as maneuvering and cooperative perception. mmWave communications can meet the bandwidth requirements of such applications, but the typically harsh propagation conditions of vehicular environments hinder the broad adoption of mmWave devices on cars. Reconfigurable in

Party responsiveness to public opinion in a multi-dimensional policy space

Party responsiveness to public opinion is a key question in the study ofdemocratic representation. While numerous studies have examined partyresponsiveness on broad ideological dimensions, there is less comparativeresearch on when and how parties respond to public opinion on morespecific issue dimensions. We aim to address this research gap by studyingparty positional responsiveness on seven issue

Risk of depression in persons with Alzheimer's disease : A national cohort study

INTRODUCTION: Depression is a risk factor and possible prodromal symptom of Alzheimer's disease (AD), but little is known about subsequent risk of developing depression in persons with AD. METHODS: National matched cohort study was conducted of all 129,410 persons diagnosed with AD and 390,088 with all-cause dementia during 1998–2017 in Sweden, and 3,900,880 age- and sex-matched controls without d

EPOS2020/EUFOREA expert opinion on defining disease states and therapeutic goals in CRSwNP

Severe chronic rhinosinusitis with nasal polyps (CRSwNP), a form of diffuse bilateral (usually type 2) CRS, is a debilitating disease with a significant impact on quality of life (QoL). With novel knowledge and treatment options becoming available, there is a growing need to update or revise key definitions to enable communication across different specialties dealing with CRS, and to agree on nove

Continuous Microwave Photon Counting by Semiconductor-Superconductor Hybrids

We present a continuous microwave photon counter based on superconducting cavity-coupled semiconductor quantum dots. The device utilizes photon-assisted tunneling in a double quantum dot with tunneling events being probed by a third dot. Our device detects both single and multiple-photon absorption events independently, thanks to the energy tunability of a two-level double-dot absorber. We show th

Mitral E-wave to stroke volume ratio displays stronger diagnostic performance to identify elevated left ventricular filling pressures than mitral E/e’ during passive leg lift : A cross-sectional study employing simultaneous echocardiography and catheterization

Background: Elevated filling pressure is a hallmark of heart failure (HF) and portends poor prognosis. Accurate diagnosis is challenging, given that patients with normal filling pressure at rest develop disproportionate elevation with sudden preload increase. We aimed to test the accuracy of the ratio between mitral inflow velocity (E) and left ventricular stroke volume (SV) to identify patients w

Site selection for nature-based solutions for stormwater management in urban areas : An approach combining GIS and multi-criteria analysis

In recent years, particularly following the definition of the UN Sustainable Development Goals (SDGs) for 2030, Nature-Based Solutions (NBS) have gained considerable attention, capturing the interest of both the scientific community and policymakers committed to addressing urban environmental issues. However, the need for studies to guide decision-makers in identifying suitable locations for NBS i

Modelling the power threshold and optimum thermal deformation of indirectly liquid-nitrogen cryo-cooled Si monochromators

Maximizing the performance of crystal monochromators is a key aspect in the design of beamline optics for diffraction-limited synchrotron sources. Temperature and deformation of cryo-cooled crystals, illuminated by high-power beams of X-rays, can be estimated with a purely analytical model. The analysis is based on the thermal properties of cryo-cooled silicon crystals and the cooling geometry. De

The role of infrastructure in achieving the sustainable development goals in Sub-Saharan Africa (SSA)

Sustainable and resilient infrastructure projects are necessary for Africa if the continent is to be successful in achieving the Sustainable Development Goals (SDGs) and agenda 2063 of the African Union (AU). The paradigm shift towards a low-carbon society cannot be achieved without sustainable and efficient infrastructure that can withstand the effects of climate change. This chapter discusses th

Tensor-valued diffusion MRI detects brain microstructural abnormalities in HIV infected individuals with cognitive impairment

Despite advancements, the prevalence of HIV-associated neurocognitive impairment remains at approximately 40%, attributed to factors like pre-cART (combination antiretroviral therapy) irreversible brain injury. People with HIV (PWH) treated with cART do not show significant neurocognitive changes over relatively short follow-up periods. However, quantitative neuroimaging may be able to detect ongo

MYC protein is a high-risk factor in mantle cell lymphoma and identifies cases beyond morphology, proliferation and TP53/p53 – a Nordic Lymphoma Group study

The transcription factor MYC is a well-described oncogene with an important role in lymphomagenesis, but its significance for clinical outcome in mantle cell lymphoma (MCL) remains to be determined. We performed an investigation of the expression of MYC protein in a cohort of 251 MCL patients complemented by analyses of structural aberrations and mRNA, in a sub-cohort of patients. Fourteen percent

Asymptotic ultraviolet-safe unification of gauge and Yukawa couplings : The exceptional case

The ultimate dream of unification models consists in combining both gauge and Yukawa couplings into one unified coupling. This is achieved by using a supersymmetric exceptional E6 gauge symmetry together with asymptotic unification in compact five-dimensional space-time. The ultraviolet fixed point requires exactly three fermion generations: one in the bulk, and the two light ones localised on the
