Lentiviral Vectors with Cellular Promoters Correct Anemia and Lethal Bone Marrow Failure in a Mouse Model for Diamond-Blackfan Anemia

Diamond-Blackfan anemia is a congenital erythroid hypoplasia and is associated with physical malformations and a predisposition to cancer. Twenty-five percent of patients with Diamond-Blackfan anemia have mutations in a gene encoding ribosomal protein S19 (RPS19). Through overexpression of RPS19 using a lentiviral vector with the spleen focus-forming virus promoter, we demonstrated that the Diamon

Bottlenecks in district heating networks and how to eliminate them - A simulation and cost study

To optimise district heating (DH) systems and simplify the transition towards the fourth generation of district heating, it is important to remove any bottlenecks existing in the DH network. DH bottlenecks are in this study defined as pipes with too high flow relative to the pipe diameter, resulting in difficulties to maintain sufficient differential pressure in the area beyond the pipe. The aim o

Soil organic matter decomposition mechanisms in ectomycorrhizal fungi

In boreal forests, ectomycorrhizal (ECM) fungi are found in soil layers containing decomposed litter and humus-rich soil organic matter (SOM). This chapter summarizes the present understanding of the mechanisms for oxidative decomposition of SOM and the hydrolysis and mobilization of organic N and P sources by ECM fungi. It discusses how these processes may influence the formation and stability of

The gut microbiota : A predisposing factor in obesity, diabetes and atherosclerosis

The cluster of pathologies comprising the metabolic syndrome (MetS) includes increased waist circumference, hyperglycemia, elevated blood pressure and hyperlipidemia. With time, these conditions present a major risk of developing obesity, type 2 diabetes and atherosclerosis. Fecal microbiota transplant (FMT) experiments performed in mice have given an intriguing foundation for a microbial-based th

Staff ratings of occupational engagement among people with severe mental illness- psychometric properties of a screening tool in the day center context

Background: Staff who plan and organize day center activities may need to observe the attendees’ performance and progression. This led us to develop a tool for that purpose, termed General Occupational Engagement in people with Severe mental illness (GOES). The aim was to investigate its psychometric properties in terms of factor structure, internal consistency, corrected item-total correlations (

Fetal and maternal temperatures during labor and delivery : a prospective descriptive study

Objective: The objective of this study is to study the fetal scalp temperature (FST) and maternal axillary temperature (MAT) during vaginal delivery relative to progression of labor, uterine contractions (UC) and epidural analgesia (EDA), and to construct normal temperature reference ranges related to stage of labor. Material and methods: Temperatures were recorded continuously in labor of 132 wom

Hydrological and hydraulic modelling applied to the mapping of flood-prone areas

Overbank flooding caused by historically high flows, such as that in the Rio Mundaú watershed (lying between the states of Alagoas and Pernambuco) in 2010, has been the cause of widespread damage. The purpose of work described in this paper was to propose a mapping of areas liable to flooding in the township of Rio Largo (Alagoas) in the Rio Mundaú watershed by means of an “off-line” coupling of t

Identification of Genetic Aberrations in Thrombomodulin Gene in Patients with Recurrent Venous Thromboembolism

Thrombomodulin (THBD) serves as a cofactor for thrombin-mediated activation of anticoagulant protein C pathway. Genetic aberrations in THBD have been studied in arterial and venous thrombosis. However, genetic changes in THBD and their role in the risk assessment of recurrent venous thromboembolism (VTE) are not well understood. The aim of the present study was to identify the genetic aberrations

Divorce and the onset of alcohol use disorder : A Swedish population-based longitudinal cohort and co-relative study

Objective: The purpose of this study was to clarify the magnitude and nature of the relationship between divorce and risk for alcohol use disorder (AUD). Method: In a population-based Swedish sample of married individuals (N=942,366), the authors examined the association between divorce or widowhood and risk for first registration for AUD. AUD was assessed usingmedical, criminal, and pharmacy regi

Role of IL-8, CRP and epidermal growth factor in depression and anxiety patients treated with mindfulness-based therapy or cognitive behavioral therapy in primary health care

Epidermal growth factor (EGF) and inflammatory markers have been associated with various neuro-psychiatric disorders. However, their role in mild to moderate depression and anxiety patients treated with mindfulness-based group therapy (mindfulness) or cognitive behavioral therapy (CBT) is not known. In this study we analyzed plasma levels of interleukin (IL)-6, IL-8, high sensitivity C-reactive pr

Association between TLR9 rs5743836 polymorphism and risk of recurrent venous thromboembolism

Recent gene knockout studies on mice have shown the role of toll-like receptor 9 (TLR9) in resolution of venous thromboembolism (VTE) through sterile inflammation. However, the role of a putative functional TLR9 polymorphism (rs5743836) in risk assessment of VTE recurrence remains unknown. The aim of our study was to investigate the TLR9 rs5743836 polymorphism in VTE patients and its association w

Malignancies in patients with anti-RNA polymerase III antibodies and systemic sclerosis : Analysis of the EULAR scleroderma trials and research cohort and possible recommendations for screening

Objective. To analyze the characteristics of anti-RNA polymerase III antibodies (anti-RNAP3)- positive patients with systemic sclerosis (SSc) in the European League Against Rheumatism Scleroderma Trials and Research group (EUSTAR) registry with a focus on the risk of cancer and the characteristics of malignancies, and the aim to provide guidelines about potential cancer screening in these patients

Clinical Application of the QRS-T Angle for the Prediction of Ventricular Arrhythmias in Patients with the Fontan Palliation

Fontan palliation patients are at risk for ventricular arrhythmias post-operatively. This study aimed to evaluate whether differences in the spatial QRS-T angle can reliably predict ventricular arrhythmias in patients who had undergone Fontan palliation. A total of 117 patients who had the Fontan palliation and post-Fontan catheterization were included. Ventricular arrhythmias were identified in n

Findings from a prospective cohort study evaluating the effects of International Health Advisors’ work on recently settled migrants’ health

Background: Several interventions have been carried out to tackle health inequalities between migrant groups, especially refugees, and native-born European populations. These initiatives are often address language or cultural barriers. One of them is the International Health Advisors (IHA) in Sweden; a peer education intervention aimed at providing health information for recently settled migrants.

Inhaler technique mastery and maintenance in healthcare professionals trained on different devices

Objective: Healthcare professionals (HCPs) are required to assess and train patients in the correct use of inhalers but are often unable to demonstrate correct technique themselves. We sought to assess the level of training required for HCPs to master and maintain device mastery when using two different dry powder inhalers (DPIs). Methods: We conducted a randomized, un-blinded, crossover study in
