Purpose: The need for sentinel lymph node biopsy (SLNB) in clinically node-negative (cN0) patients is currently questioned. Our objective was to investigate the cost-effectiveness of a preoperative noninvasive lymph node staging (NILS) model (an artificial neural network model) for predicting pathological nodal status in patients with cN0 breast cancer (BC). Methods: A health-economic decision-ana

BackgroundOut-of-hospital cardiac arrest (OHCA) survivors generally report good health-related quality of life, but physical aspects of health seem more affected than other domains. Limitations in physical function after surviving OHCA have received little attention.AimsTo describe physical function 6 months after OHCA and compare it with a group of ST elevation myocardial infarction (STEMI) contr

BACKGROUND: Transmission of coronavirus disease 2019 (COVID-19) can occur through inhalation of fine droplets or aerosols containing infectious virus. The objective of this study was to identify situations, patient characteristics, environmental parameters, and aerosol-generating procedures (AGPs) associated with airborne severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus.METHODS:

We report a novel approach for single-shot planar imaging of CH3 radicals in premixed methane and air flames. A 213 nm beam from the 5th harmonic of an Nd:YAG laser was resonantly absorbed by the CH3 radicals, which were excited to the highly pre-dissociative upper level and dissociated to H2 and CH (X), as the main dissociation channel. The CH radicals were consequently excited by a 388 nm beam f

Background: Balance Body Tape (BBT) is a recently developed taping-method with the aim to reduce pain and improve posture through change in movement behavior. However, the potential effects of a treatment with BBT are scarcely documented. Therefore, the aim with this study was to investigate the effect of a three-week Balance body tape-treatment on the intensity of perceived neck, shoulder and bac

Background: The requirement concerning formal education for emergency medical dispatcher (EMD) is debated and varies, both nationally and internationally. There are few studies on the outcomes of emergency medical dispatching in relation to professional background. This study aimed to compare calls handled by an EMD with and without support by a registered nurse (RN), with respect to priority leve

Survival after blood or marrow transplantation (BMT) for inborn errors of metabolism (IEM) is excellent; however, the burden of morbidity in long-term survivors of BMT for IEM remains understudied. This study examined the risk of chronic health conditions (CHC) in ≥2-year survivors of allogeneic BMT for IEM performed between 1974 and 2014 using the BMT Survivor Study. In this retrospective cohort

BACKGROUND: The relative cardiovascular safety of gonadotropin-releasing hormone (GnRH) antagonists compared with GnRH agonists in men with prostate cancer and known atherosclerotic cardiovascular disease remains controversial. METHODS: In this international, multicenter, prospective, randomized, open-label trial, men with prostate cancer and concomitant atherosclerotic cardiovascular disease were

BACKGROUND: In the Netherlands, surgery for peritoneal metastases of colorectal cancer (PMCRC) is centralised, whereas PMCRC is diagnosed in all hospitals. This study assessed whether hospital of diagnosis affects treatment selection and overall survival (OS).METHODS: Between 2005 and 2015, all patients with synchronous PMCRC without systemic metastases were selected from the Netherlands Cancer Re

Influencers i sig själva utgör personliga varumärken, inbegripet personnamn, image, koncept på sociala medier, utseende m.m. Vidare innebär yrket ofta att influencers mot ersättning marknadsför näringsidkares produkter eller tjänster på sina sociala medier. Näringsidkare använder sig således av influencers varumärke samt den redan etablerade relationen som finns mellan influencers och deras följarInfluencers as individuals can be viewed as personal trademarks, which includes name, image, layout on social media, appearance etc. Furthermore, the profession often includes that influencers for remuneration markets companies’ products or services on their social media channels. By doing so, the companies utilize the already established relationship between the influencer and his/her followers.

The Yaw Power Backup System (YPBS) is a safety system that needs to be incorporated in the Wind Power Plant (WPP) in order to provide emergency power during a power outage. The YPBS enables the Wind Turbine Generator (WTG) to perform a yawing operation in extreme weather conditions. The yawing operation ensures the rotor is aligned with incoming wind, minimizing the acting forces on the blades and

Disaster management is a field, where any kind of information is essential for planning and rescue operations. The availability of real-time data on a portable device, such as a smartphone, can be very useful for emergency workers, during rescue operations and citizens as well. Augmented mobile reality is a system where the users can see overlayed data and visuals in the real environment through t

The purpose of this master’s thesis is to provide a contribution to the research body regarding consumer returns, particularly within the online fashion retail industry. A quantitative data analysis approach is chosen and two main methods are used: data study that aims to identify patterns and interesting relationships in the data, and a simulation study that uses real input data to attempt to ide

Public procurement and the purchasing of goods, services and works comprises about 14% of the European gross domestic product (GDP). Procurement initiatives, guidance and tools therefore can have significant influence to leverage demands for more sustainable and circular products and services. This study explores the current circular public procurement (CPP) landscape, looking at barriers and oppo

Most migratory bird species divide their migration in stages of flight and stopovers. They use these stopovers to refuel the energy reserves needed to face their long migration journeys. These stopovers are an important element to determine the overall migration speed. Time spent on migration and arrival date to the wintering grounds have been demonstrated to have a large effects the following bre

Kolloider är partiklar i storleksordningen nm till μm. De är viktiga i biologiska system, där exempelvis proteiner är en typ av kolloid. Att studera kolloider ger oss därför insikt i hur till exempel proteiner byggs upp och interagerar. I detta fall försökte vi tillverka kolloidala molekyler, alltså kolloider som interagerar med varandra genom ett specifikt antal bindningar i väl definierade positThe ability of thermoresponsive, amine-functionalized microgel particles to take part in microgelmicrogel inter-cross-linking has previously been reported in the literature, in connection to applications such as for example the formation of stimuli-responsive colloidal gels and colloidosomes [1]. This thesis deals with the synthesis of such thermoresponsive, cross-linkable microgels and their subs

Under 1990-talet och fram till 2007 var det vanligt förekommande att byggnader uppfördes med en så kallad enstegstätad fasadkonstruktion. Det byggdes omkring 15 000 – 30 000 bostadshus med denna konstruktion, vilka omfattar 110 000 – 160 000 bostäder. Ett stort antal av byggnaderna uppförda med den aktuella fasadkonstruktionen fick fukt- och mögelskador redan efter några år. År 2007 uppmärksammaDuring the 1990s and up until 2007, it was common that buildings were erected with a construction method known as External Thermal Insulation Composite System Walls. Around 15 000 – 30 000 residential buildings were built using this method and these constitute 110 000 – 160 000 residences. A large number of the buildings constructed with the this method got damp and mold damage after only a few y

Generellt sett har cyklande alltid väjningsplikt när de korsar en körbana från en cykelbana. Syftet med detta projekt är att jämföra effekten av omvänd väjningsplikt, det vill säga då motorfordon har skyldighet att väja för cyklande, med traditionell cykelöverfart där cyklande ska ge företräde. Avsikten är att bedöma framkomligheten för cyklande vid cykelöverfarter med olika väjningsreglering och Generally cyclists are obliged to give way when crossing a roadway from a bicycle path. The purpose of this thesis is to compare the effect of reverse right of way, that is when motor vehicles have duty to give cyclists way, with traditional crossing were cyclists are obliged to yield. The intention is to assess the level of service of cyclist on bicycle crossings with different yielding regulatio
