Prognostic role of serum thymidine kinase 1 kinetics during neoadjuvant chemotherapy for early breast cancer

BACKGROUND: Emerging data support the use of thymidine kinase 1 (TK1) activity as a prognostic marker and for monitoring of response in breast cancer (BC). The long-term prognostic value of TK1 kinetics during neoadjuvant chemotherapy is unclear, which this study aimed to elucidate. METHODS: Material from patients enrolled to the single-arm prospective PROMIX trial of neoadjuvant epirubicin, docet

Precisionsmedicin kan bli viktig även vid komplexa sjukdomar

Complex diseases represent a number of common disorders such as allergic conditions, cardiovascular, metabolic and chronic inflammatory diseases. These diseases are caused by a combination of genetic, environmental and lifestyle factors. This complex etiology creates challenges when it comes to diagnostics, follow-up programs and treatment. Although exact disease mechanisms are yet to be elucidate

Comparison of measuring strategies for frequency-and time-domain induced polarization

Spectral induced polarization (SIP) is an increasingly interesting technique for field investigations since it can provide valuable information on the properties of the subsurface deposits or groundwater units. Field measurements can be carried out in the frequency domain (FD) or in the time domain (TD) but should lead to the same spectral subsurface description. IP measurements are superimposed b

An agnostic study of associations between abo and rhd blood group and phenome-wide disease risk

Background: There are multiple known associations between the ABO and RhD blood groups and disease. No systematic population-based studies elucidating associations between a large number of disease categories and blood group have been conducted. Methods: Using SCANDAT3-S, a comprehensive nationwide blood donation-transfusion database, we modelled outcomes for 1,217 disease categories including 70

Semiconductor nanowire array for transparent photovoltaic applications

The surface area of a building that could potentially be used for Building Integrated Photovoltaics would increase dramatically with the availability of transparent solar cells that could replace windows. The challenge is to capture energy from outside the visible region (UV or IR) while simultaneously allowing a high-quality observation of the outside world and transmitting sufficient light in th

Quick Systemic Lupus Activity Questionnaire (Q-SLAQ) : A simplified version of SLAQ for patient-reported disease activity

Objectives Most indices of disease activity in SLE combine physicians' assessments and laboratory tests. However, there is also a need to capture patients' perspectives of disease activity. Consequently, we need new, preferably quick and easy instruments to collect this information, which can be very useful for online consultations and registry purposes. We compared patients' assessments of SLE di

Sun-induced fluorescence and near-infrared reflectance of vegetation track the seasonal dynamics of gross primary production over Africa

The carbon cycle of tropical terrestrial vegetation plays a vital role in the storage and exchange of atmospheric CO2. But large uncertainties surround the impacts of land-use change emissions, climate warming, the frequency of droughts, and CO2 fertilization. This culminates in poorly quantified carbon stocks and carbon fluxes even for the major ecosystems of Africa (savannas and tropical evergre

Association of transport time with adverse outcome in paediatric trauma

BACKGROUND: It is unclear how the length of prehospital transport time affects outcome in paediatric trauma. This study evaluated the association of transport time from alarm to arrival at hospital with adverse outcome in paediatric trauma patients in Sweden. METHODS: This was a retrospective study based on prospectively collected data from the Swedish trauma registry between 2012 and 2019 of chil

Association of incident fragility fractures in patients hospitalised due to unexplained syncope and orthostatic hypotension

Background Fragility fractures are caused by low-energy insults such as falls from standing height or less and pose a growing health challenge as their incidence rises with increasing age. Impaired orthostatic blood pressure response and a number of cardiovascular biomarkers have been previously identified as risk factors for fractures. It is likely that severe episodes of syncope and orthostatic

Clinical outcomes with unselected use of an ultrathin-strut sirolimus-eluting stent : a report from the Swedish Coronary Angiography and Angioplasty Registry (SCAAR)

Aims: The aim of this study was to assess the real-world clinical performance of a sirolimus-eluting ultrathin-strut drug-eluting stent (DES) (Orsiro) in a large nationwide cohort of patients undergoing percutaneous coronary intervention (PCI). Methods and results: From the Swedish Coronary Angiography and Angioplasty Registry, the two-year outcomes of 4,561 patients implanted with Orsiro (Orsiro

Hairy cell leukemia and COVID-19 adaptation of treatment guidelines

Standard treatment options in classic HCL (cHCL) result in high response rates and near normal life expectancy. However, the disease itself and the recommended standard treatment are associated with profound and prolonged immunosuppression, increasing susceptibility to infections and the risk for a severe course of COVID-19. The Hairy Cell Leukemia Foundation (HCLF) has recently convened experts a

Defining the Emerging Blood System During Development at Single-Cell Resolution

Developmental hematopoiesis differs from adult and is far less described. In the developing embryo, waves of lineage-restricted blood precede the ultimate emergence of definitive hematopoietic stem cells (dHSCs) capable of maintaining hematopoiesis throughout life. During the last two decades, the advent of single-cell genomics has provided tools to circumvent previously impeding characteristics o

Predicting Type 1 Diabetes Onset using Novel Survival Analysis with Biomarker Ontology

Type 1 diabetes (T1D) is a chronic autoimmune disease that affects about 1 in 300 children and up to 1 in 100 adults during their life-time1. Improvements in early prediction of T1D onset may help prevent diagnosis for diabetic ketoacidosis, a serious complication often associated with a missed or delayed T1D diagnosis. In addition to genetic factors, progression to T1D is strongly associated with

Control-Based Resource Management for Storage of Video Streams

Distributed surveillance systems typically consist of multiple cameras that need to store some fraction of their video streams at a central storage node. The disk space of this node constitutes a shared resource. In the paper the disk space allocation is formulated as a PI control problem and a new method for enforcing global resource constraints inspired by anti-windup tracking is proposed. The a

Changing practice patterns in European cataract surgery as reflected in the European Registry of Quality Outcomes for Cataract and Refractive Surgery 2008 to 2017

PURPOSE: To study practice patterns in European cataract surgery over a 10-year period. SETTING: European clinics affiliated to the European Registry of Quality Outcomes for Cataract and Refractive Surgery (EUREQUO). DESIGN: Registry cohort study. METHODS: The EUREQUO contains preoperative, intraoperative, and postoperative parameters reported by surgeons in many European clinics. All data reporte

Reduced WNT5A signaling in melanoma cells favors an amoeboid mode of invasion

Tumor cells invade and spread via either a mesenchymal or an amoeboid mode of migration. Amoeboid tumor cells have a rounded morphology and pronounced RhoA activity. Here, we investigate how WNT5A signaling, a tumor promotor in melanoma, relates to Rho GTPase activity and amoeboid migration. We compared melanoma cells with low (HTB63 cells) and high (WM852 cells) WNT5A expression. HTB63 cells exhi

Post-reconstruction enhancement of [18F]FDG PET images with a convolutional neural network

Background: The aim of the study was to develop and test an artificial intelligence (AI)-based method to improve the quality of [18F]fluorodeoxyglucose (FDG) positron emission tomography (PET) images. Methods: A convolutional neural network (CNN) was trained by using pairs of excellent (acquisition time of 6 min/bed position) and standard (acquisition time of 1.5 min/bed position) or sub-standard

Eco-chemical mechanisms govern phytoplankton emissions of dimethylsulfide in global surface waters

The anti-greenhouse gas dimethylsulfide (DMS) is mainly emitted by algae and accounts for more than half of the total natural flux of gaseous sulfur to the atmosphere, strongly reducing the solar radiation and thereby the temperature on Earth. However, the relationship between phytoplankton biomass and DMS emissions is debated and inconclusive. Our study presents field observations from 100 freshw
