Lymphatic Endothelial Cells Control Initiation of Lymph Node Organogenesis.

Lymph nodes (LNs) are strategically situated throughout the body at junctures of the blood vascular and lymphatic systems to direct immune responses against antigens draining from peripheral tissues. The current paradigm describes LN development as a programmed process that is governed through the interaction between mesenchymal lymphoid tissue organizer (LTo) cells and hematopoietic lymphoid tissue inducer (LTi) cells. Using cell-type-specific ablation of key molecules involved in lymphoid organogenesis, we found that initiation of LN development is dependent on LTi-cell-mediated activation of lymphatic endothelial cells (LECs) and that engagement of mesenchymal stromal cells is a succeeding event.

Interventions to slow cardiovascular aging: Dietary restriction, drugs and novel molecules.

Cardiovascular aging is a highly dynamic process. Despite the fact that cardiovascular function and structure change with age, they can still be modulated even in aged humans. The most prominent approaches to improve age-dependent vascular changes include dietary restriction and pharmacologic agents interacting with signaling pathways implicated in this context.

A highly conserved sequence of the viral TAP inhibitor ICP47 is required for freezing of the peptide transport cycle.

The transporter associated with antigen processing (TAP) translocates antigenic peptides into the endoplasmic reticulum (ER) lumen for loading onto MHC class I molecules. This is a key step in the control of viral infections through CD8+ T-cells. The herpes simplex virus type-1 encodes an 88 amino acid long species-specific TAP inhibitor, ICP47, that functions as a high affinity competitor for the peptide binding site on TAP.

Towards the concept of disease-modifier in post-stroke or vascular cognitive impairment: a consensus report.

Background: Vascular cognitive impairment (VCI) is a complex spectrum encompassing post-stroke cognitive impairment (PSCI) and small vessel disease-related cognitive impairment. Despite the growing health, social, and economic burden of VCI, to date, no specific treatment is available, prompting the introduction of the concept of a disease modifier.

Consensus And Suggestions: Within this clinical spectrum, VCI and PSCI remain advancing conditions as neurodegenerative diseases with progression of both vascular and degenerative lesions accounting for cognitive decline.

High dietary quality of non-toxic cyanobacteria for a benthic grazer and its implications for the control of cyanobacterial biofilms.

Background: Mass occurrences of cyanobacteria frequently cause detrimental effects to the functioning of aquatic ecosystems. Consequently, attempts haven been made to control cyanobacterial blooms through naturally co-occurring herbivores. Control of cyanobacteria through herbivores often appears to be constrained by their low dietary quality, rather than by the possession of toxins, as also non-toxic cyanobacteria are hardly consumed by many herbivores.

Use of Collagen Matrix for Augmentation of the Peri-implant Soft Tissue at the Time of Immediate Implant Placement.

Aim: The aim of this study was to determine the treatment outcome of the use of a porcine monolayer collagen matrix (mCM) to augment peri-implant soft tissue in conjunction with immediate implant placement as an alternative to patient's own connective tissue.

Materials And Methods: A total of 27 implants were placed immediately in 27 patients (14 males and 13 females, with a mean age of 52.2 years) with simultaneous augmentation of the soft tissue by the use of a mCM.

German Adjuvant Intergroup Node-positive Study (GAIN): a phase III trial comparing two dose-dense regimens (iddEPC versus ddEC-PwX) in high-risk early breast cancer patients.

Background: Dose-dense (dd) regimens are one of the preferred options for the adjuvant treatment of breast cancer patients with intermediate to high risk. The German Adjuvant Intergroup Node-positive trial aimed at optimizing intense dd (idd) strategies by evaluating drug combinations and the addition of capecitabine.

Patients And Methods: Women (aged 18 years and biologically <65 years) with histologically involved axillary lymph nodes were randomly assigned to receive three courses each of epirubicin (E) 150 mg/m2, paclitaxel (P) 225 mg/m2 and cyclophosphamide (C) 2500 mg/m2 (reduced to 2000 mg/m2 after recruitment of 1200 patients) q2w intravenously (i.

Extended RAS analysis and correlation with overall survival in advanced pancreatic cancer.

Background: Mutations in the KRAS gene can be detected in about 70-90% of pancreatic cancer (PC) cases. Whether these mutations have a prognostic or predictive value remains elusive. Furthermore, the clinical relevance of the extended RAS (KRAS+NRAS) mutational status is unclear in PC.

Peripheral Immunological Cells in Pregnant Women and their Change during Diabetes.

During the last decades the incidence of diabetes has dramatically increased as well as the number of pregnant diabetic women. There is still missing data regarding patterns and shifts of immune cell populations due to pregnancy with or without diabetes. The study aimed to investigate the impact of pregnancy, type 1 diabetes (T1D) and gestational diabetes mellitus (GDM) on different immune cells in female.

Paraneoplastic limbic encephalitis with SOX1 and PCA2 antibodies and relapsing neurological symptoms in an adolescent with Hodgkin lymphoma.

Background: Immune cross-reactivity between malignant and normal tissues causes the rare, so called paraneoplastic syndrome (PS). In approximately 60% of the patients, various onconeural antibodies are detectable in the cerebrospinal fluid (CSF) and are associated with typical tumour entities.

Methods: We report an unusual case of paraneoplastic limbic encephalitis (PLE) in a 17-year-old adolescent with classical Hodgkin lymphoma.

Peripheral blood cytogenetics allows treatment monitoring and early identification of treatment failure to lenalidomide in MDS patients: results of the LE-MON-5 trial.

Unlabelled: Transfusion-dependent patients with low- or intermediate-1-risk myelodysplastic syndrome, <5% bone marrow (BM) blasts and isolated 5q-deletion received lenalidomide within the German MDS study group phase-II clinical trial LE-MON-5 (EudraCT:2008-001866-10) of the University of Duesseldorf, Germany. Cytogenetic monitoring was performed by chromosome banding analyses (CBA) of BM cells and fluorescence in situ hybridization (FISH) analyses of peripheral blood (PB) mononuclear CD34+ cells using extended probe panels. Out of 144 patients screened for study enrollment, 24% failed to meet inclusion criteria due to cytogenetic findings.

Cyclophosphamide-based stem cell mobilization in relapsed multiple myeloma patients: A subgroup analysis from the phase III trial ReLApsE.

Objective: Analysis of the efficiency and toxicity of cyclophosphamide-based stem cell mobilization in patients with relapsed multiple myeloma (RMM).

Methods: Peripheral blood stem cells (PBSCs) were mobilized with high dose cyclophosphamide (2 g/m daily on days 1 and 2) and G-CSF plus pre-emptive/rescue plerixafor in RMM patients (first to third relapse) treated within the ReLApsE trial of the German-Speaking Myeloma Multicenter Group (GMMG).

Results: Mobilization was initiated with high-dose cyclophosphamide (HD-CY) and G-CSF in 30 patients.

An experimental examination of the effort-reward imbalance model of occupational stress: Increased financial reward is related to reduced stress physiology.

Effort-reward imbalance in the workplace is linked to a variety of negative health and organisational outcomes, but it has rarely been assessed experimentally. We manipulated reward (while keeping effort constant) in a within-subjects design with female participants (N=60) who were randomly assigned to high and standard reward conditions within a simulated office environment. Self-report, behavioural (task performance), and physiological (heart rate variability, salivary alpha amylase) measures assessed the impact of increased financial reward.

Changes of the peri-implant soft tissue thickness after grafting with a collagen matrix.

Background: The aim of this study was to determine the treatment outcome of the use of a porcine monolayer collagen matrix (mCM) to increase soft-tissue volume as a part of implant site development.

Materials And Methods: Implants were placed in single sites in 27 patients. In the test group, mCM was used for soft-tissue augmentation.

Acculturation and health-related quality of life: results from the German National Cohort migrant feasibility study.

Objectives: We assessed the association between acculturation and health-related quality of life (HRQoL) among persons with a Turkish migrant background in Germany.

Methods: 1226 adults of Turkish origin were recruited in four German cities. Acculturation was assessed using the Frankfurt Acculturation Scale resulting in four groups (integration, assimilation, separation and marginalization).

The best of both worlds: A combined approach for analyzing microalgal diversity via metabarcoding and morphology-based methods.

An increasing number of studies use next generation sequencing (NGS) to analyze complex communities, but is the method sensitive enough when it comes to identification and quantification of species? We compared NGS with morphology-based identification methods in an analysis of microalgal (periphyton) communities. We conducted a mesocosm experiment in which we allowed two benthic grazer species to feed upon benthic biofilms, which resulted in altered periphyton communities. Morphology-based identification and 454 (Roche) pyrosequencing of the V4 region in the small ribosomal unit (18S) rDNA gene were used to investigate the community change caused by grazing.

The effect of slow release insemination on pregnancy rates: report of two randomized controlled pilot studies and meta-analysis.

Purpose: A modified application technique of intrauterine insemination (IUI) is slow release insemination (SRI), first described by Muharib et al. (Hum Reprod 7(2):227-229, 1992), who postulated higher pregnancy rates with a slow release of spermatozoa for 3 h.

Methods: To investigate this approach, two randomized controlled, cross-over pilot studies were performed from 2004 to 2006 in Israel and Germany to compare SRI with the standard bolus IUI.

Student ERI: Psychometric properties of a new brief measure of effort-reward imbalance among university students.

Background: Psychosocial stress among university students, particularly medical students, is considered a widely prevalent problem. There is a need for valid measurement of an adverse psychosocial stress environment in university settings. The aim of this study was to examine the psychometric properties of a newly developed short student version of the effort-reward imbalance (ERI) questionnaire in a sample of medical students.

Prevention of contrast-induced acute kidney injury in patients undergoing cardiovascular procedures-a systematic review and network meta-analysis.

Background: Interventional diagnostic and therapeutic procedures requiring intravascular iodinated contrast steadily increase patient exposure to the risks of contrast-induced acute kidney injury (CIAKI), which is associated with death, nonfatal cardiovascular events, and prolonged hospitalization. The aim of this study was to investigate the efficacy of pharmacological and non-pharmacological treatments for CIAKI prevention in patients undergoing cardiovascular invasive procedures with iodinated contrast.

Methods And Findings: MEDLINE, Google Scholar, EMBASE and Cochrane databases as well as abstracts and presentations from major cardiovascular and nephrology meetings were searched, up to 22 April 2016.

Osteonecrosis develops independently from radiological leukemic infiltration of bone in adolescents with acute lymphoblastic leukemia - first findings of the OPAL trial.

Osteonecrosis (ON) is a debilitating side effect of anti-leukemic treatment. Thus far, the role of leukemic infiltration (LI) of bone is unclear. The first 30 children aged ≥10 years, who were enrolled in the ongoing OPAL trial and had MRI studies at diagnosis and at 6 months, were analyzed.

Longitudinal study of social participation and well-being among persons with spinal cord injury and their partners (pro-WELL).

Purpose: Social participation is an important determinant of well-being. Among persons with disabilities, and with spinal cord injury (SCI) in particular, opportunities for social participation are restricted and may impact well-being. The longitudinal pro-WELL study aims to investigate associations of 2 major domains of social participation with well-being: (1) availability and quality of close social relationships and (2) acting in core social roles (eg, paid work).

The role and structure of the multidisciplinary team in the management of advanced Parkinson's disease with a focus on the use of levodopa-carbidopa intestinal gel.

A multidisciplinary team (MDT) approach is increasingly recommended in Parkinson's disease (PD) treatment guidelines, but no standard of care exists for such an approach, and the guidelines do not provide clarification on how it should be implemented. This paper reviews evidence of MDT interventions in people with PD and provides expert clinical perspectives for an MDT approach, with a focus on advanced PD and levodopa-carbidopa intestinal gel (carbidopa-levodopa enteral suspension in the USA). The key recommendations are to enable the best possible treatment of people with PD locally by facilitating a close structured collaboration of different health care professionals working in a fixed network structure; to refer people with PD to established MDT centers in a timely manner; to establish regular meetings for the MDT enabling interdisciplinary exchange and learning; to optimize individual treatment and carefully evaluate available treatment options; to ensure treatment decisions are agreed jointly between people with PD, their caregivers, family, and health care professional; and to include specialists outside of neurology from adjuvant medical departments as necessary when implementing advanced therapies.

Mesenchymal stromal cells in myeloid malignancies.

Myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML) are clonal myeloid disorders characterized by hematopoietic insufficiency. As MDS and AML are considered to originate from genetic and molecular defects of hematopoietic stem and progenitor cells (HSPC), the main focus of research in this field has focused on the characterization of these cells. Recently, the contribution of BM microenvironment to the pathogenesis of myeloid malignancies, in particular MDS and AML has gained more interest.
