Purpose: To evaluate the prevalence of acute nausea and emesis during concurrent chemoradiotherapy (CRT) with emphasis on the influence of patient- and treatment-related risk factors and prophylactic antiemetic medication.

Patients And Methods: A total of 335 patients treated with different intravenous standard chemoradiotherapy protocols in the inpatient setting were included in this retrospective study. Acute nausea and emesis, scored according to the CTC (version 3.

Comparison of ELF, FibroTest and FibroScan for the non-invasive assessment of liver fibrosis.

Background: FibroTest (FT) is the most frequently used serum fibrosis marker and consists of an algorithm of five fibrosis markers (alfa2-macroglobulin, apolipoproteinA1, haptoglobin, GGT, bilirubin). The Enhanced Liver Fibrosis (ELF) test consists of an algorithm of three fibrosis markers (hyaluronic acid, amino-terminal propeptide-of-type-III-collagen, tissue-inhibitor of matrix-metaloproteinase-1). While a systematic review has shown comparable results for both individual markers, there has been no direct comparison of both markers.

Restoration of the tumor suppressor p53 by downregulating cyclin B1 in human papillomavirus 16/18-infected cancer cells.

Abrogation of functional p53 is responsible for malignant cell transformation and the maintenance of malignant state of human papillomavirus-infected cancer cells. Thus, restoration of p53 has been regarded as an important strategy for molecular intervention combating papillomavirus-associated malignancies. We show here that depleting cyclin B1 stabilizes and reactivates p53 in papillomavirus-infected cervical cancer cell lines HeLa and CaSki.

Albinterferon Alfa-2b was not inferior to pegylated interferon-α in a randomized trial of patients with chronic hepatitis C virus genotype 1.

Background & Aims: The current standard of care for patients with chronic hepatitis C virus (HCV) genotype 1 is once-weekly pegylated interferon-α (Peg-IFNα) plus daily ribavirin for 48 weeks. We evaluated the efficacy/safety of albinterferon alfa-2b (albIFN), a novel, long-acting, genetic fusion polypeptide of albumin and IFNα-2b.

Methods: In the phase 3 ACHIEVE-1 trial, 1331 patients were assigned equally to 3 open-label, 48-week treatment groups: Peg-IFNα-2a 180 μg every week, or albIFN 900 or 1200 μg every 2 weeks administered subcutaneously, with weight-based oral ribavirin 1000-1200 mg/day.

Seroepidemiology of parvovirus B19 in the Frankfurt am Main area, Germany: evaluation of risk factors.

Background: Parvovirus B 19 is a virus that is distributed by respiratory droplets. It is known to be an initiator of erythema infectiosum (children's fifth disease), with erythroblasts being the target cells of infection. In case of vertically transmission, hydrops fetalis has been documented.

Intracerebral mass bleeding in a term neonate: manifestation of hereditary protein S deficiency with a new mutation in the PROS1 gene.

Background: Vitamin K deficiency is the major cause of coagulopathy-induced intracranial bleeding in term neonates and is considered first in any term neonate with severe hemorrhage. The most common manifestation of hereditary prothrombotic disorders during the neonatal period is thrombosis of the A. cerebri media or sinus thrombosis.

Aortic root stability in bicuspid aortic valve disease: patch augmentation plus reduction aortoplasty versus modified David type repair.

Objectives: The unreinforced aortic root, in bicuspid aortic valve disease, has been shown to dilate and cause recurrent regurgitation. The objective of this study was to determine whether reduction aortoplasty can reliably prevent aortic root dilatation after aortic valve repair in bicuspid disease.

Methods: A total of 66 patients, with a mean age of 41.

Initial experience with 18F-fluoroethylcholine PET/CT in staging and monitoring therapy response of advanced renal cell carcinoma.

Objective: The use of 18F-fluoroethylcholine (FEC) PET/ CT in staging and monitoring therapy response of advanced renal cell carcinoma (RCC) was prospectively analysed.

Methods: Preliminary results of two patients with metastatic RCC who underwent tumour nephrectomy as well as FEC PET/CT before and 10 weeks after two cycles of tyrosine kinase inhibitor therapy are presented.

Results: All in all, 18 tumour lesions were detected by baseline PET/CT, of which 10 (56%) were positive in FEC PET and 17 (94%) visible on contrast-enhanced computed tomography (ceCT).

Phenotypic and measurement influences on heritability estimates in childhood ADHD.

Twin studies described a strongly heritable component of attention-deficit/hyperactivity disorder (ADHD) in children and adolescents. However, findings varied considerably between studies. In addition, ADHD presents with a high rate of comorbid disorders and associated psychopathology.

Twice-weekly treatment with tacrolimus 0.03% ointment in children with atopic dermatitis: clinical efficacy and economic impact over 12 months.

Background: Rational healthcare decision-making based on clinical and economic evidence is essential to provide the best possible care for patients with atopic dermatitis (AD).

Objective: To evaluate treatment outcomes, resource use and cost associated with twice-weekly tacrolimus 0.03% ointment treatment vs.

Heparin-induced non-necrotizing skin lesions: rarely associated with heparin-induced thrombocytopenia.

Summary Background: Recently, there has been an increasing number of reports regarding adverse skin reactions to subcutaneous heparin administration. Case series have implied that heparin-induced skin lesions are predominantly associated with life-threatening heparin-induced thrombocytopenia (HIT) in at least 22% of patients. Skin lesions, therefore, have been included in clinical scores for HIT.

Preconditioning by toll-like receptor 2 agonist Pam3CSK4 reduces CXCL1-dependent leukocyte recruitment in murine myocardial ischemia/reperfusion injury.

Objective: To test whether preconditioning with a toll-like receptor (TLR) 2 agonist protects against myocardial ischemia and reperfusion by interfering with chemokine CXCL1 release from cardiomyocytes.

Design: C3H mice were challenged with vehicle or synthetic TLR2 agonist Pam3Cys-Ser-Lys4 (Pam3CSK4; 1 mg/kg) 24 hrs before myocardial ischemia (20 mins) and reperfusion (2 hrs or 24 hrs). Infarct size, troponin T release, and leukocyte recruitment were quantified.

Real-time elastography and contrast-enhanced ultrasound for the assessment of thyroid nodules.

Objective: Work-up of thyroid nodules remains challenging. Recent technologies enable determination of tissue elasticity and perfusion using ultrasound devices. The aim of the present study was to evaluate real-time elastography (RTE) and contrast-enhanced ultrasound with Sonovue (CEUS) for the differentiation of benign and malignant thyroid nodules.

Characterization of resistance to the protease inhibitor boceprevir in hepatitis C virus-infected patients.

Unlabelled: Boceprevir is a hepatitis C virus (HCV) nonstructural protein (NS) 3/4A protease inhibitor that is currently being evaluated in combination with peginterferon alfa-2b and ribavirin in phase 3 studies. The clinical resistance profile of boceprevir is not characterized in detail so far. The NS3 protease domain of viral RNA was cloned from HCV genotype 1-infected patients (n = 22).

Once-daily treatment with saquinavir mesylate (2000 mg) and ritonavir (100 mg) together with a fixed-dose combination of abacavir/lamivudine (600/300 mg) or tenofovir/emtricitabine (245/200 mg) in HIV-1-infected patients.

Objectives: To investigate the feasibility and pharmacokinetics of a once-daily regimen of 2000 mg saquinavir mesylate boosted with 100 mg ritonavir.

Patients And Methods: Patients successfully treated with 1000 mg saquinavir boosted with 100 mg ritonavir twice daily together with two nucleoside or nucleotide reverse transcriptase inhibitors [N(t)RTIs] who were switched to 2000 mg saquinavir with 100 mg ritonavir once daily with unchanged N(t)RTI therapy were analysed. CD4 cells, HIV-RNA PCR and metabolic parameters were compared between baseline and 3, 6, 9 and 12 months after the switch.

18F-Fluorodeoxyglucose-PET/CT to evaluate tumor, nodal disease, and gross tumor volume of oropharyngeal and oral cavity cancer: comparison with MR imaging and validation with surgical specimen.

Introduction: The purpose of this paper is to evaluate the impact of adding combined 18F-PET/CT to MRI for T and N staging of the oral and oropharyngeal cancer and calculation of the gross tumor volume (GTV) having histopathology as reference standard.

Methods: PET/CT and MRI were performed in 66 patients with suspected oral and oropharyngeal cancer (41 primary tumors/25 recurrent tumors) and nodal disease (114 nodes). Statistical analysis included the McNemar test, sensitivity, specificity for the diagnostic modalities as well as regression analysis, and Bland-Altman graphs for calculated tumor volumes.

Multimerization of peptide mimotopes for blocking of factor VIII neutralizing antibodies.

About 30 % of patients with severe hemophilia A develop neutralizing antibodies (inhibitors) to coagulation factor VIII (FVIII) upon treatment with exogenous factor preparations. Two peptides, C6 (NPVENMMDRDSQ) and H10 (QSPWQTWFTRAL), that mimic putative inhibitor epitopes (mimotopes), were previously selected by phage display screening of plasma samples from patients with inhibitors. Synthetic peptide mimotopes inhibited IgG binding to FVIII (IC(50): 30-50 microM).

Wnt5a increases cardiac gene expressions of cultured human circulating progenitor cells via a PKC delta activation.

Background: Wnt signaling controls the balance between stem cell proliferation and differentiation and body patterning throughout development. Previous data demonstrated that non-canonical Wnts (Wnt5a, Wnt11) increased cardiac gene expression of circulating endothelial progenitor cells (EPC) and bone marrow-derived stem cells cultured in vitro. Since previous studies suggested a contribution of the protein kinase C (PKC) family to the Wnt5a-induced signalling, we investigated which PKC isoforms are activated by non-canonical Wnt5a in human EPC.

Sutureless aortic valve replacement with the 3f Enable aortic bioprosthesis.

Purpose: Important comorbid conditions in elderly patients referred for aortic valve replacement require alternative treatment options with possible reduction of the extracorporeal circuit time and reliable hemodynamic features. We report on clinical experiences with the sutureless, nitinol-stented 3f Enable (ATS Medical, Minneapolis, MN) aortic valve prosthesis in 32 patients.

Description: The procedure was performed using cardiopulmonary bypass with cardioplegic arrest.

Management of hepatitis C virus genotype 2 or 3 infection: treatment optimization on the basis of virological response.

Current guidelines recommend a full 24-week regimen for all patients undergoing treatment for genotype 2 or 3 hepatitis C virus (HCV) infection. Recent data from two large randomized studies, one with pegylated interferon-alpha2a plus ribavirin (RBV) and one with pegylated interferon-alpha2b plus RBV assessed treatment duration and on-treatment predictors, such as rapid virological response (RVR; HCV RNA <50 IU/ml at week 4) or sustained virological response rates. Overall, these studies have shown that abbreviated regimens are generally less effective than standard 24-week regimens in genotype 2 or 3 patients because of a higher rate of relapse.
