Endoscopic grading of the gastroesophageal valve in patients with symptoms of gastroesophageal reflux disease (GERD)

BACKGROUND: It has been suggested that endoscopic grading of the gastroesophageal flap valve is a good predictor of the reflux status.METHODS: To test this hypothesis, 268 symptomatic patients underwent endoscopic grading of the gastroesophageal valve using Hill's classification, with grades I through IV. Esophageal acid exposure, lower esophageal sphincter characteristics, and the degree of esoph

Depression is associated with poor prognosis in patients with chronic obstructive pulmonary disease - a systematic review

INTRODUCTION: Patients with depression have significantly increased mortality from somatic disease. The purpose of this article was to review studies that investigate if there is a prognostic association with depression as co-morbidity in patients with chronic obstructive pulmonary disease (COPD). We chose the following outcomes: mortality, suicide behaviour, risk of COPD exacerbation, use of prim

Effect of Radiotherapy After Breast-Conserving Surgery Depending on the Presence of Tumor-Infiltrating Lymphocytes : A Long-Term Follow-Up of the SweBCG91RT Randomized Trial

PURPOSE: The effects of radiotherapy (RT) on the basis of the presence of stromal tumor infiltrating lymphocytes (TILs) have not been studied. The purpose of this study was to analyze the association of TILs with the effect of postoperative RT on ipsilateral breast tumor recurrence (IBTR) in a large randomized trial. METHODS: In the SweBCT91RT (Swedish Breast Cancer Group 91 Radiotherapy) trial, 1

Metabolomic analysis of male combat veterans with post traumatic stress disorder

Posttraumatic stress disorder (PTSD) is associated with impaired major domains of psychology and behavior. Individuals with PTSD also have increased co-morbidity with several serious medical conditions, including autoimmune diseases, cardiovascular disease, and diabetes, raising the possibility that systemic pathology associated with PTSD might be identified by metabolomic analysis of blood. We so

Special Issue: Mapping the Discursive Opportunities for Radical-Right Populist Politics across Eastern Europe

This special issue brings together scholars of media, sociology, and political science to examine the discursive opportunities for radical-right populist politics across Eastern Europe. The articles concentrate on such soft factors as the role of media, the radicalization of public discourse, and the communication repertoires of radical-right populist actors across the region. The contributions em

Effect of Catheter Ablation vs Antiarrhythmic Medication on Quality of Life in Patients With Atrial Fibrillation : The CAPTAF Randomized Clinical Trial

Importance: Quality of life is not a standard primary outcome in ablation trials, even though symptoms drive the indication.Objective: To assess quality of life with catheter ablation vs antiarrhythmic medication at 12 months in patients with atrial fibrillation.Design, Setting, and Participants: Randomized clinical trial at 4 university hospitals in Sweden and 1 in Finland of 155 patients aged 30

Warming response of peatland CO2 sink is sensitive to seasonality in warming trends

Peatlands have acted as net CO2 sinks over millennia, exerting a global climate cooling effect. Rapid warming at northern latitudes, where peatlands are abundant, can disturb their CO2 sink function. Here we show that sensitivity of peatland net CO2 exchange to warming changes in sign and magnitude across seasons, resulting in complex net CO2 sink responses. We use multiannual net CO2 exchange obs

Unravelling the mechanisms of CE-SSFP in imaging myocardium at risk : The effect of relaxation times on myocardial contrast

Purpose: The aim of this study was to investigate the contrast mechanisms of Contrast-enhanced steady-state free-precession (CE-SSFP) through the utilization of Bloch simulations in an experimental porcine model and in patients with acute myocardial infarction. Methods: Six pigs and ten patients with myocardial infarction underwent CMR and tissue characterization at 1.5 T whereas a Bloch simulatio

Changes in waterbird occurrence and abundance at their northern range boundaries in response to climate warming : importance of site area and protection status

Climate warming is driving changes in species distribution, but habitat characteristics can interact with warming temperatures to affect populations in unexpected ways. We investigated wintering waterbird responses to climate warming depending on habitat characteristics, with a focus on the northern boundary of their non-breeding distributions where winter climatic conditions are more extreme. At

CDK4 is co-amplified with either TP53 promoter gene fusions or MDM2 through distinct mechanisms in osteosarcoma

Amplification of the MDM2 and CDK4 genes on chromosome 12 is commonly associated with low-grade osteosarcomas. In this study, we conducted high-resolution genomic and transcriptomic analyses on 33 samples from 25 osteosarcomas, encompassing both high- and low-grade cases with MDM2 and/or CDK4 amplification. We discerned four major subgroups, ranging from nearly intact genomes to heavily rearranged

No recovery of soil respiration four years after fire and post-fire management in a Nordic boreal forest

The long-term carbon storage capacity of the boreal forest is under threat from the increasing frequency and intensity of wildfires. In addition to the direct carbon emissions during a fire, the burnt forest often turns into a net carbon emitter after fire, leading to large additional losses of carbon over several years. Understanding how quickly forests recover after a fire is therefore vital to

Modeling the evolution of culture-adapted human embryonic stem cells

The long-term culture of human embryonic stem (ES) cells is inevitably subject to evolution, since any mutant that arises with a growth advantage will be selectively amplified. However, the evolutionary influences of population size, mutation rate, and selection pressure are frequently overlooked. We have constructed a Monte Carlo simulation model to predict how changes in these factors can influe

Housing adaptations and home modifications

Worldwide, but subject to substantial variations across countries, housing adaptations and home modifications constitute important and common interventions in occupational therapy practice. Starting out from the notion that occupational performance is the outcome of person–environment–occupation (P–E–O) transactions, such interventions are applicable with all kinds of clients with occupational per

Longitudinal enumeration and cluster evaluation of circulating tumor cells improve prognostication for patients with newly diagnosed metastatic breast cancer in a prospective observational trial

Background: Circulating tumor cells (CTCs) carry independent prognostic information in patients with metastatic breast cancer (MBC) on different lines of therapy. Moreover, CTC clusters are suggested to add prognostic information to CTC enumeration alone but their significance is unknown in patients with newly diagnosed MBC. We aimed to evaluate whether longitudinal enumeration of circulating tumo

Unpacking package free shopping: Alternative retailing and the reinvention of the practice of shopping

The aim of this paper is to understand how the practice of package free shopping takes shape and is established. Taking a shopping-as-practice approach, and drawing on an ethnographic study of a Swedish ecological food store, this paper shows that to be able to successfully remove a key artefact - packaging - from the practice of shopping, the practice itself must be reinvented. Developing package

Populism, ontological insecurity and Hindutva : Modi and the masculinization of Indian politics

In an era increasingly defined by insecurity and populist politics, India has emerged as a forceful ontological security provider under the leadership of Marendra Modi. If ontological security is about finding a safe (imagined) haven, then ontological insecurity is about the lack of such a space in narrative terms. Drawing on Lacanian understandings of ‘the imaginary’ as something that can fill an

Comparative financing analysis and political economy of noncommunicable diseases

The pandemic of chronic non-communicable diseases (NCDs) poses substantial challenges to the health financing sustainability in high-income and low/middle income countries (LMICs). The aim of this review is to identify the bottle neck inefficiencies in NCDs attributable spending and propose sustainable health financing solutions. The World Health Organization (WHO) introduced the "best buy" concep

People's conceptual environmental appraisals of urban space in daylight and electric light

Urban spaces should be resilient, inclusive and safe for all residents including children, elderly and vulnerable groups. This implies that urban planning, management and design should provide public spaces that support human needs of active mobility, social interaction and psychological restoration across seasonal and diurnal variation in natural light. Environmental psychology postulates that an

Discovering Subgroups of Children With High Mortality in Urban Guinea-Bissau : Exploratory and Validation Cohort Study

divided the data set temporally, assessing the persistence of identified subgroups over different periods. The reassessment of mortality risk used the targeted maximum likelihood estimation (TMLE) method to achieve more robust causal modeling. Results: We analyzed data from 21,005 children. The mortality risk (6 weeks to 3 years of age) was 5.2% (95% CI 4.8%-5.6%) for children born between 2003 an
