AIM: Self-expanding metallic stents (SEMS) as bridge to surgery have been questioned due to the fear of perforation and tumour spread. This study aimed to compare SEMS and stoma as bridge to surgery in acute malignant large bowel obstruction in the Swedish population. METHOD: Medical records of patients identified via the Swedish Colorectal Cancer Register 2007-2009 were collected and scrutinized.
Gathering information from the environment allows animals to make informed behavioural decisions, with individuals sampling information either privately or via social cues from group members. Environmental noise, however, may disrupt the ability of animals to gather information in their environment. Therefore, social interactions could be disrupted by environmental noise, or adapted to mitigate th
Two-wavelength and two-color laser-induced incandescence (2λ–2C-LII) was used to study the absorption properties of three types of cold soot of different maturity from a mini-CAST soot generator. LII fluence curve analysis allowed for estimating absorption wavelength dependence in terms of dispersion coefficients ξ by the use of two excitation wavelengths (532 and 1064 nm). The estimated ξ (based
A novel multi-source data fusion method based on Bayesian inference (BIF) was proposed in this study to blend the advantages of in-situ observations and remote sensing estimations for obtaining accurate chlorophyll-a (Chla) concentration in Lake Taihu (China). Two error models (additive and multiplicative) were adopted to construct the likelihood function in BIF; the BIF method was also compared w
Among the interesting questions related to tongue-twisters is the question how fast syllables of different types can be repeated. A simple pilot experiment with strings of open syllables such as [tatata...], [stastasta...], [strastrastra ...] was carried out. Differences in the results are interpreted as being due to individual differences in motor skills and to differences in the phonetic materia
Biomarkers for neurodegenerative diseases are needed to improve the diagnostic workup in the clinic but also to facilitate the development and monitoring of effective disease-modifying therapies. Positron emission tomography methods detecting amyloid-β and tau pathology in Alzheimer’s disease have been increasingly used to improve the design of clinical trials and observational studies. In recent
Persistent pain after groin hernia repair is a major health problem. Sleep disturbance is associated with heightened pain sensitivity. The main objective of this study was to examine the role of sleep disturbance in the development and long-term maintenance of chronic postherniorrhaphy inguinal pain (CPIP), with exploration of sex differences. From 2012 to 2017, a national cohort of patients with
Purpose: Nobel Prize winner Daniel Kahneman’s work on modes of “thinking” provides a comprehensive text which is little explored in respect of work with people who have an intellectual or developmental disability. This paper aims to explore the potential of this work to change staff development and practice. Design/methodology/approach: Key themes from Thinking Fast, and Slow (Kahneman, 2011) are
Contact allergy (CA) is not uncommon in the population, including to various fragrance allergens. If not diagnosed correctly, allergic contact dermatitis (ACD) may ensue, because targeted allergen avoidance is not possible. The primary objective of the study is to estimate the prevalence of CA to seven fragrance materials in patients with suspected ACD across Europe. Based on the outcome, a conclu
Background: Eating disorders significantly impact physical health and have negative psychosocial consequences. The global burden of anorexia nervosa and bulimia nervosa among young females is estimated to account for 1.9 million disability-adjusted life years. Early identification of disordered eating attitudes is critical for preventing the progression to more severe forms of eating disorders; ho
We survey results on Chebyshev polynomials centered around the work of H. Widom. In particular, we discuss asymptotics of the polynomials and their norms and general upper and lower bounds for the norms. Several open problems are also presented.
This is the first of three volumes that form the Encyclopedia of Special Functions, an extensive update of the Bateman Manuscript Project. Volume 1 contains most of the material on orthogonal polynomials, from the classical orthogonal polynomials of Hermite, Laguerre and Jacobi to the Askey–Wilson polynomials, which are the most general basic hypergeometric orthogonal polynomials. Separate chapter
