Decrease in circulating plasmacytoid dendritic cells during short-term systemic normobaric hypoxia.

Background: During exposure to high altitude, the immune system is altered. During hypoxia, an increase in interleukin (IL)-6 and high sensitivity C-reactive protein (hs-CRP), and an increase in natural killer cells and decrease in T cells in blood was shown. However, the impact of hypoxia on dendritic cells has not been investigated yet.

GSK-3β inhibition attenuates CLP-induced liver injury by reducing inflammation and hepatic cell apoptosis.

Liver dysfunction has been known to occur frequently in cases of sepsis. Excessive inflammation and apoptosis are pathological features of acute liver failure. Recent studies suggest that activation of glycogen synthase kinase- (GSK-) 3β is involved in inflammation and apoptosis.

Determinants of neointimal proliferation and stent coverage after intracoronary therapy with drug-eluting devices in stable coronary artery disease: role of endothelial progenitor cells and interleukin-1 family cytokines.

Background: Endothelial progenitor cells (EPCs) and cytokines seem to play a pivotal role in arterial healing after stent implantation. Using optical coherence tomography (OCT) as a high-resolution imaging technique, we aimed to assess the influence of circulating EPCs and levels of Il-1 cytokines on stent coverage and in-stent proliferation.

Methods: Eighty-nine patients were randomly treated with either Xience V drug-eluting stent (DES; n = 48) or bare-metal stent (BMS) postdilated with the SeQuent Please drug-eluting balloon (DEB; n = 41).

In-vitro activity of taurolidine on single species and a multispecies population associated with periodontitis.

The antimicrobial activity of taurolidine was compared with minocycline against microbial species associated with periodontitis (four single strains and a 12-species mixture). Minimal inhibitory concentrations (MICs) and minimal bactericidal concentrations (MBCs), killing as well as activities on established and forming single-species biofilms and a 12-species biofilm were determined. The MICs of taurolidine against single species were always 0.

Reciprocal causation models of cognitive vs volumetric cerebral intermediate phenotypes for schizophrenia in a pan-European twin cohort.

In aetiologically complex illnesses such as schizophrenia, there is no direct link between genotype and phenotype. Intermediate phenotypes could help clarify the underlying biology and assist in the hunt for genetic vulnerability variants. We have previously shown that cognition shares substantial genetic variance with schizophrenia; however, it is unknown if this reflects pleiotropic effects, direct causality or some shared third factor that links both, for example, brain volume (BV) changes.

Ischemic preconditioning protects against liver ischemia/reperfusion injury via heme oxygenase-1-mediated autophagy.

Objectives: Ischemic preconditioning exerts a protective effect in hepatic ischemia/reperfusion injury. The exact mechanism of ischemic preconditioning action remains largely unknown. Recent studies suggest that autophagy plays an important role in protecting against ischemia/reperfusion injury.

Stent coverage and neointimal proliferation in bare metal stents postdilated with a Paclitaxel-eluting balloon versus everolimus-eluting stents: prospective randomized study using optical coherence tomography at 6-month follow-up.

Background: In this randomized trial, strut coverage and neointimal proliferation of a therapy of bare metal stents (BMSs) postdilated with the paclitaxel drug-eluting balloon (DEB) was compared with everolimus drug-eluting stents (DESs) at 6-month follow-up using optical coherence tomography. We hypothesized sufficient stent coverage at follow-up.

Methods And Results: A total of 105 lesions in 90 patients were treated with either XIENCE V DES (n=51) or BMS postdilated with the SeQuent Please DEB (n=54).

Clinical diagnosis of sepsis and the combined use of biomarkers and culture- and non-culture-based assays.

Sepsis is among the most common causes of death in hospitalized patients, and early recognition followed by immediate initiation of therapy is an important concept to improve survival in these patients. According to the definition of sepsis, diagnosis of sepsis requires the recognition of the systemic inflammatory response syndrome (SIRS) caused by infection as well as recognition of possible infection-related organ dysfunctions for diagnosis of severe sepsis or septic shock. Both SIRS and organ dysfunctions may occur frequently in hospitalized patients for various reasons.

1,25-Dihydroxyvitamin D3 prevents bone loss of the secondary spongiosa in arthritic rats by an increase of bone formation and mineralization and inhibition of bone resorption.

Background: Active vitamin D metabolites have been shown to have protective effects in experimental arthritis especially when used as preventive treatment. However, because the direct effects of 1,25-dihydroxyvitamin D3 (1,25(OH) 2D3) on bone formation and resorption are very complex, the net effect of 1,25(OH)2D3 on histomorphometric parameters of bone turnover and mineralisation should be investigated. Therefore, we examined the influence of 1,25(OH)2D3 therapy on arthritis-induced alterations of periarticular and axial bone as well as disease activity, inflammation and joint destruction in antigen-induced arthritis (AIA) of the rat.

Comparison of multilocus sequence typing, RAPD, and MALDI-TOF mass spectrometry for typing of β-lactam-resistant Klebsiella pneumoniae strains.

Extended spectrum of β-lactam (ESBL) resistance of Klebsiella pneumoniae has become an increasing problem in hospital infections. Typing of isolates is important to establish the intrahospital surveillance of resistant clones. In this study, the discriminatory potential of randomly amplified polymorphic DNA and matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) analyses were compared with multilocus sequence typing (MLST) by using 17 β-lactam-resistant K.

A European multicenter randomized noninferiority trial comparing 180 W GreenLight XPS laser vaporization and transurethral resection of the prostate for the treatment of benign prostatic obstruction: 12-month results of the GOLIATH study.

Purpose: We present the 1-year results of the GOLIATH prospective randomized controlled trial comparing transurethral resection of the prostate to GreenLight XPS for the treatment of men with nonneurogenic lower urinary tract symptoms due to prostate enlargement. The updated results at 1 year show that transurethral resection of the prostate and GreenLight XPS remain equivalent, and confirm the therapeutic durability of both procedures. We also report 1-year followup data from several functional questionnaires (OABq-SF, ICIQ-SF and IIEF-5) and objective assessments.

Updated S2K AWMF guideline for the diagnosis and follow-up of obstructive sialadenitis--relevance for radiologic imaging.

The interdisciplinarily developed German S2k AWMF guideline for the treatment of obstructive sialadenitis represents a new standard in the guideline program of the AWMF, the German Society for Consultants and the clinical disciplines working in the field of diseases of the head and neck region. In the last few years new diagnostic and therapeutic possibilities have been established in obstructive chronic Sialadenitis offering individually optimized therapeutic strategies. Only a few years ago extirpation of the whole affected gland was the only relevant therapy option.

Suture granuloma mimicking a recurrent sacro-coccygeal pilonidal sinus after Limberg flap.

Sacro-coccygeal pilonidal sinus disease is classified as an asymptomatic, acutely abscess-forming or chronic subcutaneous inflammation in the sacro-coccygeal region featuring characteristic pits in the bottom cleft. Due to high rates of recurrence, two flap techniques have been established in the course of the past three decades. One of them is the Karydakis operation, the other option is a rotation flap named Limberg procedure.

Predictive factors for survival and recurrence rate in patients with node-negative gastric cancer--a European single-centre experience.

Purpose: Gastric cancer is a common disease with poor prognosis. Lymph node involvement is the strongest prognostic factor regarding survival in curatively (R0) resected patients. The aim of this study was to determine if a subgroup with higher risk for tumour recurrence exists in patients with node-negative gastric cancer.

Psychological interventions for acute pain after open heart surgery.

Background: Acute postoperative pain is one of the most disturbing complaints in open heart surgery, and is associated with a risk of negative consequences. Several trials investigated the effects of psychological interventions to reduce acute postoperative pain and improve the course of physical and psychological recovery of participants undergoing open heart surgery.

Objectives: To compare the efficacy of psychological interventions as an adjunct to standard care versus standard care alone or standard care plus attention in adults undergoing open heart surgery on pain, pain medication, mental distress, mobility, and time to extubation.

Preschool children's taste acceptance of highly concentrated fluoride compounds: effects on nonverbal behavior.

Objective: The aim of this video-based study was to examine the taste acceptance of children between the ages of 2 and 5 years regarding highly concentrated fluoride preparations in kindergarten-based preventive programs.

Study Design: The fluoride preparation Duraphat was applied to 16 children, Elmex fluid to 15 children, and Fluoridin N5 to 14 children. The procedure was conducted according to a standardized protocol and videotaped Three raters evaluated the children's nonverbal behavior as a measure of taste acceptance on the Frankl Behavior Rating Scale.

Effectiveness of a new fluoride varnish for caries prevention in pre-school children.

Objective: To investigate the effectiveness of a new fluoride varnish (Clinpro White Varnish, 3MEspe, Seefeld, Germany) with regard to the caries incidence within a 2-year period

Study Design: A non-randomized sample of 400 children from the Kyffhäuser district (Thuringia, Germany) was divided into a fluoride group (FG, biannual application of fluoride varnish) and control group (CG, no intervention). (Non-)cavitated caries lesions were recorded using World Health Organization (WHO) and Universal Visual Scoring System (UniViSS) criteria. Parents were given questionnaires to gather information about their socio-economic status (SES).

Early diastolic strain rate predicts response to heart failure therapy in patients with dilated cardiomyopathy.

The aim of this prospective study was to assess the value of speckle tracking echocardiographic (2D-STE) parameters to predict response to heart failure therapy in patients with dilated cardiomyopathy (DCM). Eighty-seven patients (mean age 51 ± 13 years) with DCM, defined as ejection fraction (EF) <45 %, left ventricular (LV) end-diastolic diameter >112 % of normal range derived from age and body surface area. Based on 2D-STE following parameters were extracted from three apical views of the LV: global longitudinal strain, systolic and diastolic strain rate (SRE).

EBV load in whole blood correlates with LMP2 gene expression after pediatric heart transplantation or allogeneic hematopoietic stem cell transplantation.

Background: Epstein-Barr virus (EBV) is associated with posttransplant lymphoproliferative disease (PTLD), and EBV load measurement is an important tool to monitor transplant patients. Although EBV DNA quantification has high sensitivity to identify patients at risk for PTLD, it lacks specificity. We examined whether EBV gene expression in peripheral B cells can increase specificity or correlates with EBV load.

Mass spectrometric profiling of cord blood serum proteomes to distinguish infants with intrauterine growth restriction from those who are small for gestational age and from control individuals.

Intrauterine growth restriction (IUGR) is a multifactorial condition in that the fetus does not reach its genetically given growth potential. Besides its contribution to perinatal mortality, it is a risk factor for cardiovascular and metabolic diseases later in life. The diagnosis is based on antenatal sonography, which allows differentiating between IUGR and fetuses that are small by constitution (small for gestational age [SGA]).

180-W XPS GreenLight laser vaporisation versus transurethral resection of the prostate for the treatment of benign prostatic obstruction: 6-month safety and efficacy results of a European Multicentre Randomised Trial--the GOLIATH study.

Background: The comparative outcome with GreenLight (GL) photoselective vaporisation of the prostate and transurethral resection of the prostate (TURP) in men with lower urinary tract symptoms due to benign prostatic obstruction (BPO) has been questioned.

Objective: The primary objective of the GOLIATH study was to evaluate the noninferiority of 180-W GL XPS (XPS) to TURP for International Prostate Symptom Score (IPSS) and maximum flow rate (Qmax) at 6 mo and the proportion of patients who were complication free.

Design, Setting, And Participants: Prospective randomised controlled trial at 29 centres in 9 European countries involving 281 patients with BPO.

Antibacterial activity of moxifloxacin on bacteria associated with periodontitis within a biofilm.

The activity of moxifloxacin was compared with ofloxacin and doxycycline against bacteria associated with periodontitis within a biofilm (single strain and mixed population) in vitro. MICs and minimal bactericidal concentrations (MBCs) of moxifloxacin, ofloxacin and doxycyline were determined against single strains and mixed populations in a planktonic state. Single-species biofilms of two Porphyromonas gingivalis and two Aggregatibacter actinomycetemcomitans strains and a multispecies biofilm consisting of 12 species were formed for 3 days.

Cryptogenic left main thrombosis: successful mechanical clot retrieval with a self-expanding trapping device.

We present the case of a 52-year-old male with ST-segment elevation myocardial infarction due to a spontaneous large left main thrombosis, without any angiographic evidence for coronary artery disease. After multiple unsuccessful attempts of thrombaspiration the large clot was mechanically retrieved by a flow restoration device that was primarily made for intracranial interventions. Intravascular ultrasound revealed marginal lumen narrowing after the intervention, but the final coronary angiogram showed a patent left main and there was no relevant stenosis remaining.

Investigation of the inter-observer variability effect on the prognostic value of somatosensory evoked potentials of the median nerve (SSEP) in cardiac arrest survivors using an SSEP classification.

Background And Purpose: We investigated the inter-observer variability in interpretation of median nerve SSEPs with regard to neurological prognosis in survivors of cardiac arrest (CA).

Methods: Four experienced neurologists analyzed 163 median nerve SSEPs on the basis of a pre-defined classification of SSEPs into five patterns (A-E), with consideration of cortical potentials up to a latency of 150ms. Of these, 133 recordings were from CA survivors and 30 were from healthy volunteers.
