Older individuals’ need for knowledge and follow-up about their chronic atrial fibrillation, lifelong medical treatment and medical controls

Older individuals with chronic atrial fibrillation (AF) often experience physical symptoms and feel psychologically unwell. In addition, these persons are prescribed lifelong medical treatment that requires regular monitoring. Through 11 individual interviews, this interpretive description study aimed to explore and describe lifelong medical treatment and the need for medical controls as experienc

The slippery slope of hematopoietic stem cell aging

The late stages of life, in most species including humans, are associated with a decline in the overall maintenance and health of the organism. This applies also to the hematopoietic system, where aging is not only associated with an increased predisposition for hematological malignancies, but also identified as a strong comorbidity factor for other diseases. Research during the last two decades h

Photoreceptor signalling is sufficient to explain the detectability threshold of insect aerial pursuers

An essential biological task for many flying insects is the detection of small, moving targets, such as when pursuing prey or conspecifics. Neural pathways underlying such 'target-detecting' behaviours have been investigated for their sensitivity and tuning properties (size, velocity). However, which stage of neuronal processing limits target detection is not yet known. Here, we investigated sever

Preoperative Aspartate Aminotransferase-to-Platelet Ratio Index Predicts Perioperative Liver-Related Complications Following Liver Resection for Colorectal Cancer Metastases

Background and Aims: There are limited data on the potential role of preoperative non-invasive markers, specifically the aspartate-to-alanine aminotransferase ratio and the aspartate aminotransferase-to-platelet ratio index, in predicting perioperative liver-related complications after hepatectomy for colorectal cancer metastases. Methods: Patients undergoing liver resection for colorectal cancer

Age-appropriate preparations for children with cancer undergoing radiotherapy : A feasibility study

The aim of this study was to test age-appropriate information and preparation procedures for children with cancer undergoing radiotherapy (RT) for feasibility and effectiveness in terms of the need for general anesthesia (GA) and anxiety. In a quasi-experimental controlled clinical trial, 17 children aged 3–18 years receiving age-appropriate preparation were compared with 16 children in a control

Improved Detection of Norovirus and Hepatitis A Virus in Surface Water by Applying Pre-PCR Processing

Quantitative reverse transcriptase polymerase chain reaction (RT-qPCR) detection of waterborne RNA viruses generally requires concentration of large water volumes due to low virus levels. A common approach is to use dead-end ultrafiltration followed by precipitation with polyethylene glycol. However, this procedure often leads to the co-concentration of PCR inhibitors that impairs the limit of det

Microfluidics-based approaches to the isolation of African trypanosomes

African trypanosomes are responsible for significant levels of disease in both humans and animals. The protozoan parasites are free-living flagellates, usually transmitted by arthropod vectors, including the tsetse fly. In the mammalian host they live in the bloodstream and, in the case of human-infectious species, later invade the central nervous system. Diagnosis of the disease requires the posi

Overall conformation of covalently stabilized domain-swapped dimer of human cystatin C in solution

Human cystatin C (HCC), a small protein, plays a crucial role in inhibition of cysteine proteases. The most common structural form of human cystatin C in crystals is a dimer, which has been evidenced both for the native protein and its mutants. In these structures, HCC dimers were formed through the mechanism of domain swapping. The structure of the monomeric form of human cystatin C was determine

Alcohol consumption and risk of urothelial cell bladder cancer in the European prospective investigation into cancer and nutrition cohort

Findings on the association between alcohol consumption and bladder cancer are inconsistent. We investigated that association in the European Prospective Investigation into Cancer and Nutrition cohort. We included 476,160 individuals mostly aged 35–70 years, enrolled in ten countries and followed for 13.9 years on average. Hazard ratios (HR) for developing urothelial cell carcinoma (UCC; 1,802 inc

Doctoral dissertations in human geography from Swedish universities 1884-2015: demographics, formats and productivity

The doctoral dissertation is a key component of postgraduate education that plays an important role for knowledge production and hence the development of a discipline. Swedish human geography currently lacks an overview of dissertations. This article fills this knowledge gap by reporting findings from a unique database covering all doctoral dissertations between 1884 and 2015. The paper focuses on

Heritability of End-Stage Renal Disease : A Swedish Adoption Study

Background/Aims: The heritability of end-stage renal disease (ESRD) among adoptees has not been examined so far. By studying adoptees and their biological and adoptive parents, it is possible to differentiate between the genetic causes and environmental causes of familial aggregation. This nationwide study aimed to disentangle the genetic and shared environmental contribution to the familial trans

European Hernia Society guidelines on prevention and treatment of parastomal hernias

Background: International guidelines on the prevention and treatment of parastomal hernias are lacking. The European Hernia Society therefore implemented a Clinical Practice Guideline development project. Methods: The guidelines development group consisted of general, hernia and colorectal surgeons, a biostatistician and a biologist, from 14 European countries. These guidelines conformed to the AG

Assessing the risk of stigma clogging in strawberry flowers due to pollinator sharing with oilseed rape

Strawberry and oilseed rape are economically important and co-flowering insect-pollinated crops that may affect each other via shared pollinators. One potential negative effect of pollinator sharing is stigma clogging, i.e. that pollen from one plant species covers the stigma and prevents pollination in the other. We tested if application of oilseed rape pollen on strawberry receptacles reduces po

Ternary Organic Solar Cells with Minimum Voltage Losses

A new strategy for designing ternary solar cells is reported in this paper. A low-bandgap polymer named PTB7-Th and a high-bandgap polymer named PBDTTS-FTAZ sharing the same bulk ionization potential and interface positive integer charge transfer energy while featuring complementary absorption spectra are selected. They are used to fabricate efficient ternary solar cells, where the hole can be tra

BUS TRIPS—A self-management program for people with cognitive impairments after stroke

Stroke is a major cause of disability worldwide and different types of impairments can affect the individual’s ability to manage everyday activities such as travel that is essential for participation in society. The purpose of this study was to investigate the feasibility of a new self-management intervention (BUS TRIPS) focusing on travelling by bus, and potential contributions to an improved abi

Weight loss for overweight patients with knee or hip osteoarthritis

This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: To determine the benefits and harms associated with weight loss in overweight individuals with knee or hip osteoarthritis in terms of pain, physical function, quality of life, and safety. Further we will have an explicit focus on quality of the weight loss intervention (including magnitude and intensity) (Herbe

Incident diabetes mellitus may explain the association between sleep duration and incident coronary heart disease

Aims/hypothesis: Sleep duration is a risk factor for incident diabetes mellitus and CHD. The primary aim of the present study was to investigate, in sex-specific analyses, the role of incident diabetes as the possible biological mechanism for the reported association between short/long sleep duration and incident CHD. Considering that diabetes is a major risk factor for CHD, we hypothesised that a

Empowerment, self and engagement in day center occupations : a longitudinal study among people with long-term mental illness
