Autoimmune markers in lymphoid malignancies.

Chronic immune stimulation such as Helicobacter pylori (hp) infection, Sjögren's syndrome or coeliac disease may initiate non-Hodgkin lymphoma (NHL). The opposite (appearance of autoimmunity) has also been reported. The aim of this study was to describe the pattern of these immune markers in patients with lymphoid malignancies. Sera from 96 patients with NHL (median age 72, range 38-88, F/M 41/55)

Efficacy and safety of varenicline and bupropion, in combination and alone, for alcohol use disorder : a randomized, double-blind, placebo-controlled multicentre trial

Background: Alcohol use disorder (AUD) is associated with an enormous burden of disease and cost to society. The dopamine deficiency hypothesis posits that negative reinforcement generated by a low brain dopamine state drives ethanol intake. Here, we evaluated the efficacy and safety of combined administration of two dopamine-enhancing drugs, varenicline (a partial nicotinic acetylcholine receptor

Coronary Artery Restenosis in Women by History of Preeclampsia

BACKGROUND: A history of preeclampsia is associated with increased risk of coronary artery disease and experimental evidence suggests that a history of preeclampsia also increases the risk of restenosis. However, the extent to which a history of preeclampsia is associated with risk of restenosis after percutaneous coronary intervention in women is unknown. METHODS AND RESULTS: We included 6065 par

Monitoring mining induced seismicity using optical fibre sensors during mine exploitation

Fibre-optic based sensing technologies are becoming popular in the field of geophysics since enable long range and high spatial resolution acoustic measurements. In this work, we present preliminary results obtained using quasi-distributed Fibre-Bragg grating sensing and Distributed Acoustic Sensing (DAS) to monitor seismic activities in an operational underground mine. 12 FBGs and 800 metres of f

Food laborers as stewards of island biocultural diversity : Reclaiming local knowledge, food sovereignty, and decolonization

Creating nutritious and ecologically regenerative food cultures depends on the local knowledge of food system laborers. Food producers in small island developing states center socioecological interdependence in their livelihoods and, as such, conserve biocultural diversity. Amid burgeoning health, economic, and climate crises brought on by colonialism, reclaiming food sovereignty requires a critic

Parental help-seeking behaviour for, and care of, a sick or injured child during the COVID-19 pandemic: a European online survey

BackgroundGlobally, the COVID-19 pandemic had a huge impact on patients and healthcare systems. A decline in paediatric visits to healthcare settings was observed, which might have been due to lower incidence of injury and infectious illness, changes in healthcare services and parental concern. The aim of our study was to examine parental experiences of help-seeking for, and care of, a sick or inj

Conversion efficiency of flight power is low, but increases with flight speed in the migratory bat Pipistrellus nathusii

The efficiency with which flying animals convert metabolic power to mechanical power dictates an individual's flight behaviour and energy requirements. Despite the significance of this parameter, we lack empirical data on conversion efficiency for most species as in vivo measurements are notoriously difficult to obtain. Furthermore, conversion efficiency is often assumed to be constant across flig

The confounding effect of snow cover on assessing spring phenology from space : A new look at trends on the Tibetan Plateau

The Tibetan Plateau is the highest and largest plateau in the world, hosting unique alpine grassland and having a much higher snow cover than any other region at the same latitude, thus representing a “climate change hot-spot”. Land surface phenology characterizes the timing of vegetation seasonality at the per-pixel level using remote sensing systems. The impact of seasonal snow cover variations

The effect of breast density on the performance of deep learning-based breast cancer detection methods for mammography

Mammographic sensitivity in breasts with higher density has been questioned. Higher breast density is also linked to an increased risk for breast cancer. Even though digital breast tomosynthesis (DBT) offers an attractive solution, for varied reasons it has not yet been widely adopted in screening. An alternative could be to boost the performance of standard mammography by using computer-aided det

Personalised breast cancer screening with selective addition of digital breast tomosynthesis through artificial intelligence

Breast cancer screening is predominantly performed using digital mammography (DM), but higher sensitivity has been demonstrated with digital breast tomosynthesis (DBT). A partial DBT screening in selected groups with a clear benefit from DBT might be more feasible than a full implementation, and using artificial intelligence (AI) to select women for DBT might be a possibility. This study used data

On the value of structural health information

Structural Health Information (SHI) may be provided by various sources such as e.g. structural health monitoring, inspections, testing and digital technologies and networks as by the Industry Internet of Things (HOT). SHI holds a high potential for industrial, life safety and sustainability value and facilitates an optimal and intelligent life cycle management of infrastructure and machinery syste

Efficiency of nearly periodic structures for mitigation of ground vibration

Periodic structures are known to produce passbands and stopbands for propagation of vibration energy within the frequency domain. Sources vibrating harmonically at a frequency within a passband can lead to propagation of energy through propagating modes over long distances. However, sources vibrating at a frequency within a stopband excite only nearfields in the form of attenuating and evanescent

Cesarean delivery and associated socioeconomic factors and neonatal survival outcome in Kenya and Tanzania: analysis of national survey data.

Background: The increasing trends in cesarean delivery are globally acknowledged. However, in many low-resource countries, socioeconomic disparities have created a pattern of underuse and overuse among lower and higher socioeconomic groups. The impact of rising cesarean delivery rates on neonatal survival is also unclear.Objective: To examine cesarean delivery and its associated socioeconomic patt

The association between common urogenital infections and cervical neoplasia – A nationwide cohort study of over four million women (2002–2018)

Background: Cervical cancer is a major cause of mortality and morbidity in women worldwide. This study aimed to estimate the association between common urogenital infections and cervical neoplasia. Methods: A multi-register national cohort study of 4,120,557 women aged ≥15 years (2002–2018) was conducted. The outcomes were cervical cancer and carcinoma in situ (Swedish Cancer Register). The main p

Correspondence between areas causing recall in breast cancer screening and artificial intelligence findings

False positive recall is a major issue in breast cancer screening and the introduction of artificial intelligence (AI) might affect which women who are unnecessarily recalled. We have investigated how an AI system works on false positive recalls at screening and compared with radiologist findings. Two-view digital mammography (DM) examinations from 656 recalled women (136 with screening detected c

Animal wastewater treatment with an improved combined Anaerobic-Aerobic System : Towards energy Self-Sufficiency

A combined anaerobic–aerobic (CAO) system is a feasible animal wastewater treatment approach, and one of the prerequisites for its sustainable application is to realise energy self-sufficiency. Here, we built an energy balance model to calculate the probability of achieving energy self-sufficiency in three CAO systems with multiple uncertainties through Monte Carlo simulation. Upon comparison with

Drivers of Going Green in Financial Markets and Corporate Networks

This dissertation is a collection of three self-contained empirical papers developing the knowledge on environmental responsibility of investors and corporations.The first paper investigates how corporate environmental performance propagates in firm networks. We find that the degree of spillover depends on the type of link between firms as well as their relative strength in the network. The effect

Phase-matched extreme-ultraviolet frequency-comb generation

Extreme ultraviolet (XUV) laser radiation is commonly produced via high-harmonic generation (HHG) in gases. The lasers that drive this process typically operate at low pulse repetition rates (10 MHz) necessary. Unfortunately, at high repetition rates, plasma accumulates in the XUV generation region and prevents phase-matching, resulting in low HHG efficiency. We use high-temperature gas mixtures t
