Ventricular-arterial coupling : definition, pathophysiology and therapeutic targets in cardiovascular disease

Introduction: The heart and arterial system are equally affected by arteriosclerosis/atherosclerosis. There is a constant interaction between the left ventricular (LV) function and the arterial system, termed ventricular-arterial coupling (VAC), which reflects the global cardiovascular efficiency. VAC is traditionally assessed by echocardiography as the ratio of effective arterial elastance (Ea) o

Efficacy and Safety of Umeclidinium/Vilanterol in Current and Former Smokers with COPD : A Prespecified Analysis of The EMAX Trial

Introduction: Smoking may reduce the efficacy of inhaled corticosteroids (ICS) in patients with chronic obstructive pulmonary disease (COPD), but its impact on bronchodilator efficacy is unclear. This analysis of the EMAX trial explored efficacy and safety of dual- versus mono-bronchodilator therapy in current or former smokers with COPD. Methods: The 24-week EMAX trial evaluated lung function, sy

Chronic breathlessness and sleep problems : A population-based survey

Objectives This study aimed to explore the relationship (presence and severity) between chronic breathlessness and sleep problems, independently of diagnoses and health service contact by surveying a large, representative sample of the general population. Setting Analysis of the 2017 South Australian Health Omnibus Survey, an annual, cross-sectional, face-to-face, multistage, clustered area system

Second primary cancers after gastric cancer, and gastric cancer as second primary cancer

Background: Second primary cancers (SPCs) are increasing, which may negatively influ-ence patient survival. Gastric cancer (GC) has poor survival and when it is diagnosed as SPC it is often the cause of death. We wanted to analyze the risk of SPCs after GC and the risk of GC as SPC after any cancer. Such bidirectional analysis is important in relation to fatal cancers because SPCs may be under-rep

Postural orientation, what to expect in youth athletes? A cohort study on data from the Malmö Youth Sport Study

Background: Studies investigating postural orientation in uninjured youth athletes are scarce. Understanding how postural orientation during functional performance tests change with age in uninjured athletes has the potential to enhance awareness of changes in performance after injury and to set realistic goals for injured athletes. Thus, the aim of this study was to explore postural orientation d

Is Neighbourhood Linking Social Capital Associated With Colorectal Cancer Incidence and Mortality? A National Cohort Study From Sweden

Past research on the social determinants of colorectal cancer (CRC) has shown that lower socioeconomic status (SES) is associated with a higher risk of CRC. Similar to SES at the individual level, the neighbourhood social environment may partly affect the development of CRC. Although one important aspect of the neighbourhood social environment is social capital, no large-scale follow-up study has

Women Born to Older Mothers Have Reduced Fertility : Evidence From a Natural Fertility Population

Are daughters of older mothers less fertile? The human mutation rate is high and increases with chronological age. As female oocytes age, they become less functional, reducing female chances at successful reproduction. Increased oocyte mutation loads at advanced age may be passed on to offspring, decreasing fertility among daughters born to older mothers. In this paper we study the effects of mate

Dyspnoea-12 and Multidimensional Dyspnea Profile : Systematic Review of Use and Properties

Context: The Dyspnoea-12 (D-12) and Multidimensional Dyspnea Profile (MDP) were specifically developed for assessment of multiple sensations of breathlessness. Objectives: This systematic review aimed to identify the use and measurement properties of the D-12 and MDP across populations, settings and languages. Methods: Electronic databases were searched for primary studies (2008-2020) reporting us

Understanding the complexity of socioeconomic disparities in smoking prevalence in sweden : A cross-sectional study applying intersectionality theory

Objectives Socioeconomic disparities in smoking prevalence remain a challenge to public health. The objective of this study was to present a simple methodology that displays intersectional patterns of smoking and quantify heterogeneities within groups to avoid inappropriate and potentially stigmatising conclusions exclusively based on group averages. Setting This is a cross-sectional observational

A Static-99R Validation Study on Individuals With Mental Disorders : 5 to 20 Years of Fixed Follow-Up After Sexual Offenses

‘The Static-99R is one of the most commonly used risk assessment instruments for individuals convicted of sexual offenses. It has been validated for use on many populations, but few studies specifically target and describe individuals with mental disorders. Additionally, research on the discriminative properties (how well the instrument separates recidivists from non-recidivists) of the instrument

BCAT1 decreases the sensitivity of cancer cells to cisplatin by regulating mTOR-mediated autophagy via branched-chain amino acid metabolism

Cisplatin is one of the most effective chemotherapy drugs and is widely used in the treatment of cancer, including hepatocellular carcinoma (HCC) and cervical cancer, but its therapeutic benefit is limited by the development of resistance. Our previous studies demonstrated that BCAT1 promoted cell proliferation and decreased cisplatin sensitivity in HCC cells. However, the exact role and mechanism

Advancing the Field of Disaster Response Management : Toward a Design Science Approach

Multiorganizational response to emergencies and disasters requires collaboration. How to improve the collective response is therefore an essential question, but not easy to answer. In disaster research, normative research with a focus on providing evidence for how to improve professional practice has traditionally received less attention than explanatory ones. The aim of this article, using insigh

Next generation bioengineering of lung tissue for transplantation

Lung transplantation is the only option for end-stage lung diseases, but organ shortage remains problematic. Generating lungs ex vivo could overcome shortages with current approaches being explored for lung tissue engineering utilizing a biologically derived, synthetic or hybrid scaffold which is seeded with cells and cultured ex vivo. Ideally, cells could be sourced from the transplant recipient

Time-resolved compositional mapping during in situ TEM studies

In situ studies using transmission electron microscopy (TEM) can provide insights to how properties, structures and compositions of nanostructures are affected and evolving when exerted to heat or chemical exposure. While high-resolved imaging can be obtained continuously, at video-framerates of hundreds of frames per second (fps), compositional analysis struggles with time resolution due to the l

Minimal clinically important differences for Dyspnea-12 and MDP scores are similar at 2 weeks and 6 months : follow-up of a longitudinal clinical study

Chronic breathlessness is a dominating symptom that restricts daily life for many people with cardiorespiratory disease [1]. Different dimensions of the symptom, such as the intensity, sensory qualities and emotional responses, can be assessed using the instruments Dyspnea-12 (D-12) [2] and the Multidimensional Dyspnea Profile (MDP) [3], which share similarities in the underlying constructs of wha

Onset of the degradation of CVD α-Al2O3 coating during turning of Ca-treated steels

The ability to control the shape, distribution and composition of non-metallic inclusions has had an important impact on many aspects of steel making. One such impact is on the machinability. Ca-treatments have shown to be able to reduce the abrasiveness of oxide inclusions, improve chip-breaking and lead to formation of deposits that reduce tool wear. However, machining Ca-treated steels with Al2

Performance and wear mechanisms of uncoated cemented carbide cutting tools in Ti6Al4V machining

The primary tool material when machining Ti6Al4V titanium alloy is uncoated straight cemented carbide. This study examines the performance of these materials during high-speed finish turning, and uses the advanced microscopy methods of SEM, (S)TEM, XEDS, and SAED to explore the fundamental tool wear mechanisms. The wear modes include a combination of flank wear and rake cratering. Four individual

Treatment outcomes in persons with severe haemophilia B in the Nordic region : The B-NORD study

Introduction: Data on outcome in persons with haemophilia B (PwHB) are limited and mainly extrapolated from studies of haemophilia A (HA). Aim: To characterize treatment outcomes in persons with severe HB in the Nordic region, with a focus on joint health, compared with matched controls with HA. Methods: PwHB attending haemophilia centres in Denmark, Finland, Norway and Sweden were enrolled and ma

Acute myeloid leukemia in patients we judge as being older and/or unfit

Definition of older age in AML is arbitrary. In the context of the clinical studies, it starts with age ≥ 60 or ≥65 years and in recent years ≥70 or 75, depending on the selection of the studied population. In clinical practice, with older age we often mean that the patient is unfit for intensive chemotherapy. Higher age overlaps with categories such as worse performance status, unfitness, co-morb
