Platelet-derived CXCL4 regulates neutrophil infiltration and tissue damage in severe acute pancreatitis

Platelets are known to play an important role in acute pancreatitis (AP) via promotion of neutrophil accumulation, although mechanisms behind platelet-dependent accumulation of neutrophils in the pancreas remain elusive. Platelets contain a wide spectrum of different pro-inflammatory compounds, such as chemokines. CXCL4 (platelet factor 4) is one of the most abundant chemokine in platelets, and we

The effects of polar excipients transcutol and dexpanthenol on molecular mobility, permeability, and electrical impedance of the skin barrier

In the development of transdermal and topical products it is important to understand how formulation ingredients interact with the molecular components of the upper layer of the skin, the stratum corneum (SC), and thereby influence its macroscopic barrier properties. The aim here was to investigate the effect of two commonly used excipients, transcutol and dexpanthenol, on the molecular as well as

Scatterer size estimation using the center frequency assessed from ultrasound time domain data

Scatterer size estimation is useful when characterizing tissue using ultrasound. In all previous studies on scatterer size, the estimations are performed in the frequency domain and are thus subjected to a trade off in time-frequency resolution. This study focused on the feasibility of estimating scatterer size in the time domain using only the ultrasound center frequency, assuming a Gaussian-shap

Bayesian Evidence Synthesis and the quantification of uncertainty in a Monte Carlo simulation

Monte Carlo simulation is a useful technique to propagate uncertainty through a quantitative model, but that is all. When the quantitative modelling is used to support decision-making, a Monte Carlo simulation must be complemented by a conceptual framework that assigns a meaningful interpretation of uncertainty in output. Depending on how the assessor or decision maker choose to perceive risk, the

Socioeconomic inequalities in breast cancer incidence and mortality in Europe - A systematic review and meta-analysis

Background: Breast cancer is the leading cause of female cancer in Europe and is estimated to affect more than one in 10 women. Higher socioeconomic status has been linked to higher incidence but lower case fatality, while the impact on mortality is ambiguous. Methods: We performed a systematic literature review and meta-analysis on studies on association between socioeconomic status and breast ca

Localization of cardiac arrhythmias : conventional noninvasive methods

Noninvasive localization of the accessory pathway (AP) in patients with the Wolff-Parkinson-White syndrome and of the site of origin of ventricular tachycardia (VT) is reviewed. 12-lead electrocardiography (ECG) is the most readily available method for localization of both the AP and the site of VT origin. Many published ECG criteria are introduced. The application of body surface potential mappin

Comparative study of eight sets of ECG criteria for the localization of the accessory pathway in Wolff-Parkinson-White syndrome

Eight sets of electrocardiographic (ECG) criteria for the localization of accessory conduction pathway (ACP) were evaluated on 182 patients with a single ACP. The Rosenbaum criteria identified 78.6% of the left-sided and 94.0% of the right-sided ACPs. Four of the other seven sets of criteria demonstrated a sensitivity higher than 70.9% and six showed a specificity higher than 74.9% in the 4-region

Comparative study of five preoperative methods for the localization of accessory pathways in the Wolff-Parkinson-White syndrome

One hundred and thirty-four cases of Wolff-Parkinson-White syndrome were studied to evaluate the relative usefulness of electrocardiography (ECG), electrophysiological studies (EPS), body surface mapping (BSM), gated blood-pool phase analysis (nuclear studies), and vectorcardiography (VCG) in the localization of the accessory pathway (ACP). In comparison with the final localization verified by int

Prevalence and genetic and environmental influences on anxiety disorders in 6-year-old twins

Background. Prevalence of childhood anxiety disorders at specific ages and genetic etiological influences on anxiety disorders in young children have been little studied. The present study reports prevalence estimates in a community sample of 6-year-old twins, and patterns of genetic and environmental influences on these early-onset anxiety disorders. Method. Using a two-phase design 4662 twin-pai

A twin study of anxiety-related behaviours in pre-school children

Background: From middle childhood onwards, substantial evidence points to phenotypic differentiation between anxiety diagnostic categories such as generalised anxiety, separation anxiety, specific phobia, and obsessive-compulsive disorders. However, little is known about the genetics of these categories and especially about the phenotypic and genetic structure of related behaviours in pre-school c

The potential for faking on the Mississippi Scale for Combat-Related PTSD

The Mississippi Scale for Combat-Related PTSD is widely used in the assessment of post-traumatic stress disorder (PTSD). The high face-validity of the scale may make it vulnerable to faking however. The present study found that the scores of individuals instructed to respond 'as if' they had PTSD did not differ from the scores of veterans with PTSD. Furthermore, although veterans who were diagnose

Social desirability and self-reported anxiety in children: An analysis of the RCMAS lie scale

There are important applied and theoretical reasons for research into the association between social desirability and self-reported anxiety in young people. The aim of this study was to examine the relationship between anxiety and social desirability in a large normative sample of 7- to 14- year-olds (N = 1,786). Participants Completed the Revised Children's Manifest Anxiety Scale and their teache

DSM-III-R anxiety disorders in children: Sociodemographic and clinical characteristics

This study investigated the characteristics of each of the specific DSM- III-R (American Psychiatric Association, 1987) anxiety disorders in a clinic sample of 188 anxiety disordered children. Characteristics examined included sociodemographic variables (age-at-intake, gender, and race of the child, and family marital and socioeconomic status) and clinical variables (disorder age-at-onset and seve

Improvement of Echocardiographic M-Mode Detection of Ventricular Precontraction in the Wolff-Parkinson-White Syndrome by Transesophageal Atrial Pacing

BACKGROUND: The purpose of this study was to evaluate the accuracy of conventional M-mode echocardiography in localizing the site of the accessory pathway in 21 patients with overt Wolff-Parkinson-White (W-P-W) syndrome during sinus rhythm (SR) and during transesophageal atrial stimulation (TAS). METHODS: The invasive electrophysiological study was used as a reference, and the results were compare

The impact of PTSD on functioning in patients seeking treatment for chronic pain and validation of the Posttraumatic Diagnostic Scale

Purpose: To assess the psychometric properties of a Swedish version of the Posttraumatic Diagnostic Scale (PDS); to investigate the prevalence of traumatic experiences, trauma types and posttraumatic stress disorder (PTSD) in a sample of patients seeking treatment for chronic pain; and to examine how indices of pain-related functioning vary with a history of traumatic exposure and PTSD diagnostic

Further validation of the Chronic Pain Values Inventory in a Swedish chronic pain sample

PurposeValue based action is an important process in the psychological flexibility model and is associated with daily functioning in people with chronic pain, but measures of it are not well-developed. The purpose of the present study was to examine the reliability and validity of a Swedish-language version of the Chronic Pain Values Inventory (CPVI) in a large sample of adults seeking treatment f

The lasting health and income effects of public health formation in Sweden

Socio-economic inequalities are remarkable in contemporary developed countries, and continue to grow. The sources of these phenomena are not understood, and there is no agreement about at which part of an individual’s life they originate, whether in adulthood or in early childhood. The literature showing that health in infancy may be an important factor of later-life health and income trajectories
