Key research questions for implementation of artificial intelligence in capsule endoscopy

Background: Artificial intelligence (AI) is rapidly infiltrating multiple areas in medicine, with gastrointestinal endoscopy paving the way in both research and clinical applications. Multiple challenges associated with the incorporation of AI in endoscopy are being addressed in recent consensus documents. Objectives: In the current paper, we aimed to map future challenges and areas of research fo

Average uranium bedrock concentration in Swedish municipalities predicts male lung cancer incidence rate when adjusted for smoking prevalence : Indication of a cumulative radon induced detriment?

Bedrock U has been used as a proxy for local indoor radon exposure. A preliminary assessment of cancer incidence rate in a cohort of 809,939 adult males living in 9 different Swedish counties in 1986 has been used to correlate the cumulative lung cancer and total cancer (excluding lung) incidence rates between 1986 and 2020, respectively with the municipality average value of bedrock U concentrati

Probing porosity in metals by electrical conductivity : Nanoscale experiments and multiscale simulations

Motivated by the significant influence of the underlying microstructure on the effective electrical properties of a material system and the desire to monitor defect evolution through non-destructive electrical characterisation, this contribution is concerned with a detailed study of conductivity changes caused by the presence of sub-microscale pores. Reducing the complexity of the material system,

Innovative Geophysical Surveys for Contaminated Site Ground Condition Characterisation, Albertslund, Denmark

Contamination of groundwater resources from industrial sites are a prevalent issue worldwide. Characteristic of contaminated site investigations is small site scale and variability of ground conditions that necessitate extensive invasive methods. Invasive methods are costly and therefore pursuit of applicable less costly non-invasive methods to characterise the site and develop a robust ConceptualContamination of groundwater resources from industrial sites are a prevalent issue worldwide.

Phase Reassignment with Efficient Estimation of Phase Difference

The recently developed Matched Phase Reassignment (MPR) gives a time-frequency local measure of phase difference between short oscillatory transient signals. However, the resulting phase estimate is not satisfactory as it has poor resolution for high oscillatory frequencies. The MPR is also sensitive to high noise levels and is computationally cumbersome. In this paper, a novel reassignment method

ROBUST PHASE DIFFERENCE ESTIMATION OF TRANSIENTS IN HIGH NOISE LEVELS

This paper presents the Reassignment Vector Phase Difference Estimator (RVPDE), which gives noise robust relative phase estimates of oscillating transient signals in high noise levels. Estimation of relative phase information between signals is of interest for direction of arrival estimation, source separation and spatio-temporal decoding in neurology as well as for soundscape analysis. The RVPDE

Forecasting, hazards, averting disasters: Implementing forecast-based early action at scale

Forecast-based early action (FbA) initiatives are diverse, with very different approaches to the timing of decisions and actions, and to the types of forecast, monitoring data and delivery mechanisms used. They are also increasingly of interest to donors and humanitarian agencies as they consider how to reduce the growing humanitarian burden and reconsider how aid is spent. FbA programming uses fo

Interaction between blood pressure and genetic risk score for bladder cancer, and risk of urothelial carcinoma in men

There is substantial genetic predisposition to bladder cancer (BC). Recently, blood pressure (BP) was positively associated with BC risk in men, but the potential interaction with genetic susceptibility for BC is unknown. We investigated a weighted genetic risk score (wGRS) of 18 BC genetic variants, BP, and their interaction, in relation to incident urothelial cancer (UC, n = 385) risk in 10,576

Stem cells, cell therapies, and bioengineering in lung biology and disease 2021

The 9th biennial conference titled “Stem Cells, Cell Therapies, and Bioengineering in Lung Biology and Diseases” was hosted virtually, due to the ongoing COVID-19 pandemic, in collaboration with the University of Vermont Larner College of Medicine, the National Heart, Lung, and Blood Institute, the Alpha-1 Foundation, the Cystic Fibrosis Foundation, and the International Society for Cell & Gen

Anti-biofilm activity of caffeine against uropathogenic E. coli is mediated by curli biogenesis

Biofilms are assemblages of sessile microorganisms that form an extracellular matrix around themselves and mediate attachment to surfaces. The major component of the extracellular matrix of Uropathogenic E. coli and other Enterobacteriaceae are curli fibers, making biofilms robust and resistant to antimicrobials. It is therefore imperative to screen antibiofilm compounds that can impair biofilm fo

Do preterm-born children and adolescents have greater need for dental care as compared to full term-born controls?

Background: Preterm birth has been shown to cause various long-term health issues. Children who were born preterm have also been observed to have more dental behaviour management problems (DBMP) during dental examinations and treatment than children born full term. It is known that dental radiographic examinations can be uncomfortable and cause anxiety in paediatric patients. Thus, our aims were t

Effects of the Japanese Nitrate Directive Plan (NDP) to curb groundwater nitrate-nitrogen content in the Miyakonojo River basin

There are urgent needs to evaluate different management techniques to improve groundwater quality. To maintain a good quality of groundwater in the Miyakonojo River Basin (MRB), Japan, the Nitrate Directive Plan (NDP) was implemented in 2004. To assess the efficiency of this plan, we performed multivariate times-series analyses on 26 years (1996–2021) of groundwater nitrate-nitrogen (NO3−-N) data

Swedish trial on embolization of middle meningeal artery versus surgical evacuation in chronic subdural hematoma (SWEMMA)—a national 12-month multi-center randomized controlled superiority trial with parallel group assignment, open treatment allocation and blinded clinical outcome assessment

Background: Chronic subdural hematoma (cSDH) is one of the most common neurosurgical disorders and the incidence is rising. The routine treatment is neurosurgical hematoma evacuation, which is associated with recurrence rates up to 10–25%. In recent years, endovascular embolization of the middle meningeal artery (eMMA) has garnered much attention due to recurrence rates as low as < 5%. Several ran

PSA : role in screening and monitoring patients with prostate cancer

The test used for early detection and monitoring of prostate cancer—prostate-specific antigen (PSA)—is one of the most accurate and frequently used tumor markers in medicine today. No tumor marker has had such a critical impact on early detection through stage-migration, and monitoring after treatment for prostate cancer as the blood test PSA. This chapter provides an overview of the PSA test and

Exploring Different User Interfaces for Velocity based Training using Smart Gym Machines : Pilot Study

With the emerging technology called the Internet of Things (IoT), we can now connect computing devices and sensors to the Internet. The IoT sensors serve to collect data, pushing it and sharing it with a whole network of connected devices. We decided to explore how to utilize IoT data to increase the user experience from a commercial gym application called Advagym. Advagym is a commercial solution

The relation of body mass index, body height, and parity to pyelonephritis : A nationwide population-based cohort study of over one million parous women (1997-2018)

Objectives: We aimed to explore the association between various physiological factors and pyelonephritis in parous women. Methods: Swedish nationwide registers were used to identify 1,073,467 parous women aged 15-50 years. The study period began in 1997 and ended in 2018, or at the first incidence of pyelonephritis, death, or emigration. Cox proportional hazards methods were used to determine haza
