Lipoprotein Particle Predictors of Arterial Stiffness after 17 Years of Follow Up : The Malmö Diet and Cancer Study

Background. Central arterial stiffness is a surrogate of cardiovascular risk and predicts cardiovascular mortality. Apolipoprotein B lipoproteins are also established cardiovascular risk factors. It is not known whether specific lipoprotein subclasses measured in the Malmö Diet and Cancer Study and previously shown to be associated with coronary heart disease also predict arterial stiffening after

The serine protease HtrA plays a key role in heat-induced dispersal of pneumococcal biofilms

Streptococcus pneumoniae (the pneumococcus) colonizes the human nasopharynx by forming multicellular biofilms. Due to the high level of asymptomatic carriage, transition to infections, such as otitis media, pneumonia, sepsis, and meningitis, occurs often enough that the pneumococcus remains a major cause of disease and death globally. Virus infection and virus-induced responses, such as increased

Comprehensive analysis of RNA binding motif protein 3 (RBM3) in non-small cell lung cancer

Aims: High expression of the RNA-binding motif protein 3 (RBM3) correlates with improved prognosis in several major types of cancer. The aim of the present study was to examine the prognostic value of RBM3 protein and mRNA expression in non-small cell lung cancer (NSCLC). Methods and results: Immunohistochemical expression of RBM3 was evaluated in surgically treated NSCLC from two independent pati

Epidemiology, bacteriology, and clinical characteristics of HACEK bacteremia and endocarditis : a population-based retrospective study

The objective was to describe the epidemiology, bacteriology, clinical presentation, risk factors for endocarditis (IE), diagnostic workup, and outcome of patients with bacteremia caused by the non-influenzae Haemophilus, Aggregatibacter, Cardiobacterium, Eikenella, and Kingella genera (HACEK). A retrospective population-based cohort of patients with bacteremia collected from 2012 to 2017 was iden

The implications of an aging population and increased obesity for knee arthroplasty rates in Sweden : a register-based study

Background and purpose — Total knee arthroplasty (TKA) has increased substantially in Sweden. We quantified the relative risk for TKA in the Swedish population for different BMI categories and age groups to investigate whether the continued increase in TKA is attributable to increased prevalence of obesity and elderly people in the population, and to put forward model predictions for coming needs

Increases in the rates of primary and revision knee replacement are reducing : a 15-year registry study across 3 continents

Background and purpose — Rates of knee replacement (KR) are increasing worldwide. Based on population and practice changes, there are forecasts of a further exponential increase in primary knee replacement through to 2030, and a corresponding increase in revision knee replacement. We used registry data to document changes in KR over the past 15 years, comparing practice changes across Sweden, Aust

von Neumann's trace inequality for Hilbert–Schmidt operators

von Neumann's inequality in matrix theory refers to the fact that the Frobenius scalar product of two matrices is less than or equal to the scalar product of the respective singular values. Moreover, equality can only happen if the two matrices share a joint set of singular vectors, and this latter part is hard to find in the literature. We extend these facts to the separable Hilbert space setting

Filtered output feedback tracking control of a quadrotor UAV

We present a tracking controller for quadrotor UAVs which uses partial state information and filters measurement noise. We show uniform almost global and locally exponential asymptotic stability of the resulting closed-loop system, which implies robustness against bounded disturbances. We illustrate the performance of the controller by means of several numerical examples, including a complex loopi

DNA concentration wave formation in pillar arrays

High throughput in particle and molecular sorting schemes is an important performance indicator and can be realized through increased volumetric processing rates or increased concentrations. Here we investigate the effect of increased concentration of high-molecular weight DNA in micropillar arrays for deterministic lateral displacement (DLD). We find that the array imposes regular fluctuations in

Accuracy of NIH Stroke Scale for diagnosing aphasia

Objectives: The National Institutes of Health Stroke Scale (NIHSS) has not been validated to diagnose aphasia in the stroke population. We therefore examined the diagnostic accuracy of NIHSS for detecting aphasia in acute ischemic stroke. Methods: Consecutive patients with acute first-ever ischemic stroke were included prospectively in Lund Stroke Register Study at Skåne University Hospital, Swede

Military Wages and Coup d’État in Spain (1850-1915): the Use of Public Spending as a Coup-Proofing Strategty : The USE of PUBLIC SPENDING AS A COUP-PROOFING STRATEGY

In 1833-1874, Spain suffered 0.7 coups per year. By contrast, the Restoration (1874-1923) saw the eradication of successful coups. This can be partially attributed to the turno pacífico, which allowed the main political parties to alternate in office without dragging the military into politics. We suggest, however, that the reduction in coup risk was also associated with a conscious budget policy.

Widespread skeptic attitudes among people with epilepsy toward generic antiseizure drugs – A Swedish survey study

Purpose: To explore associations between the characteristics of people with epilepsy (PWE) and their attitudes toward generic substitution of antiseizure drugs (ASDs) in epilepsy. Methods: This was a cross-sectional survey study directed at adults with epilepsy using selected brand drugs: Keppra®, Lamictal®, Lyrica® or Topimax®. Symptoms of anxiety and depression, sense of self-efficacy, and belie

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

Evaluation of a flat fielding method for simultaneous DBT and MI acquisition

We are developing a prototype system for simultaneous digital breast tomosynthesis (DBT) and mechanical imaging (MI). MI maps the local pressure distribution during clinical exams, to distinguish breast abnormalities from the normal tissue. Both DBT alone, and MI when combined with digital mammography, have demonstrated the ability to reduce false positives; however, the benefit of combining DBT w

Engineering human hematopoietic environments through ossicle and bioreactor technologies exploitation

The bone marrow microenvironment contains cellular niches that maintain the pool of hematopoietic stem and progenitor cells and support hematopoietic maturation. Malignant hematopoietic cells also co-opt normal cellular interactions to promote their own growth and evade therapy. In vivo systems used to study human hematopoiesis have been developed through transplantation into immunodeficient mouse

Shrinking targets and eventually always hitting points for interval maps

We study shrinking target problems and the set of eventually always hitting points. These are the points whose first n iterates will never have empty intersection with the nth target for sufficiently large n. We derive necessary and sufficient conditions on the shrinking rate of the targets for to be of full or zero measure especially for some interval maps including the doubling map, some quadrat

Roadmap to functional characterization of the human intestinal microbiota in its interaction with the host

It is known for more than 100 years that the intestinal microbes are important for the host's health and the last decade this is being intensely studied with a focus on the mechanistic aspects. Among the fundamental functions of the intestinal microbiome are the priming of the immune system, the production of essential vitamins and the energy harvest from foods. By now, several dozens of diseases,
