Introduction: Impaired glucose homeostasis is a significant risk factor for cardiometabolic diseases, whereas the efficacy of available standard therapies is limited, mainly because of poor adherence. This post-marketing study assessed the glucose-lowering potential of a synbiotic-based formulation.

Methods: One hundred ninety-two participants were enrolled in a digital nutrition program with continuous glucose monitoring (CGM) and received a study product comprising DSM 32315 and L-alanyl-L-glutamine.

Inadequate Choline Intake in Pregnant Women in Germany.

Choline is an essential nutrient that is involved in various developmental processes during pregnancy. While the general adequate choline intake (AI) for adults has been set at 400 mg/day by the European Food Safety Authority (EFSA), an AI of 480 mg/day has been derived for pregnant women. To date, the choline intake of pregnant women in Germany has not been investigated yet.

Palatinose (Isomaltulose) and Prebiotic Inulin-Type Fructans Have Beneficial Effects on Glycemic Response and Gut Microbiota Composition in Healthy Volunteers-A Real-Life, Retrospective Study of a Cohort That Participated in a Digital Nutrition Program.

It is well-appreciated that the diet is a crucial tool to counteract cardiometabolic disturbances due to its impact on blood glucose concentration and gut microbiome. This retrospective analysis aimed to examine whether the inclusion of isomaltulose and prebiotic inulin-type fructans (ITF) into the habitual diet has an impact on glycemic control and gut microbiota. Furthermore, we examined interindividual differences in glycemic response to sugar replacement with isomaltulose.

[Opinion Survey of Paediatricians on Vaccination Status of Refugee Children - Challenges of a Medical Connection to the Regular Outpatient Care System].

Background: In addition to the primary health care of refugees, their integration into the regular outpatient care system should be ensured. Initial data suggest that a gap of vaccination among (school) children of refugee families might have emerged in the period between the first general inspection on arrival (the first central health measure) and the transition to the local health care system.

Objectives: The aim of this study was to obtain the opinion of practicing paediatricians regarding the vaccination status of refugee children to examine whether a variance in the measles, mumps, rubella (varicella) vaccination schedule might have emerged between the periods of initial admission and school enrolment examination.

How prepared are we for cross-border outbreaks? An exploratory analysis of cross-border response networks for outbreaks of multidrug resistant microorganisms in the Netherlands and Germany.

Background: The emergence and spread of multidrug resistant microorganisms is a serious threat to transnational public health. Therefore, it is vital that cross-border outbreak response systems are constantly prepared for fast, rigorous, and efficient response. This research aims to improve transnational collaboration by identifying, visualizing, and exploring two cross-border response networks that are likely to unfold during outbreaks involving the Netherlands and Germany.

[Causes, Diagnostic and Therapeutical Procedures of Malassimilation].

Patients with malassimilation suffer from disturbed exploitation of available nutrients, which can affect macro- and micronutrients. Malassimilation can be subdivided in maldigestion and malabsorption. Many different disorders, especially gastrointestinal diseases, can lead to malassimilation.

Expression of PRL-3 regulates proliferation and invasion of breast cancer cells in vitro.

Purpose: The protein tyrosine phosphatase PRL-3 plays an important role in cancer cell migration, invasion and metastasis. In breast cancer, PRL-3 is overexpressed in 70-75% of tumors and even more frequently in lymph node metastases. Moreover, PRL-3 overexpression in breast cancer is associated with an adverse disease outcome.

ETAR antagonist ZD4054 exhibits additive effects with aromatase inhibitors and fulvestrant in breast cancer therapy, and improves in vivo efficacy of anastrozole.

Endothelin-1 (ET-1) and endothelin A receptor (ETAR) contribute to the development and progression of breast carcinomas by modulating cell proliferation, angiogenesis, and anti-apoptosis. We investigated antitumoral effects of the specific ETAR antagonist ZD4054 in breast cancer cells and xenografts, and assessed antitumoral efficacy of the combinations of ZD4054 with aromatase inhibitors and fulvestrant. Gene expression changes were assessed by quantitative real-time PCR.

Differential effects of aromatase inhibitors and antiestrogens on estrogen receptor expression in breast cancer cells.

Background: Estrogen receptors (ER) alpha and beta play an important role in breast cancer. Recently, systemic adjuvant endocrine therapy with selective estrogen receptor modulator (SERM) tamoxifen has been challenged by aromatase inhibitors. Compared to antiestrogens, third-generation aromatase inhibitors (anastrozole and letrozole) exhibit an improved efficacy and tolerability.

Differential roles for membrane-bound and soluble syndecan-1 (CD138) in breast cancer progression.

The heparan sulfate proteoglycan syndecan-1 (Sdc1) modulates cell proliferation, adhesion, migration and angiogenesis. Proteinase-mediated shedding converts Sdc1 from a membrane-bound coreceptor into a soluble effector capable of binding the same ligands. In breast carcinomas, Sdc1 overexpression correlates with poor prognosis and an aggressive phenotype.

Targeting the endothelin system: novel therapeutic options in gynecological, urological and breast cancers.

The endothelin system comprises the three peptide hormones endothelin (ET)-1, -2, -3, their G protein-coupled receptors, endothelin-A-receptor (ET(A)R) and endothelin-B-receptor (ET(B)R), and the enzymes of endothelin biosynthesis and degradation. In the past two decades, an impressive amount of data has been accumulated investigating the role of the endothelin system in a variety of malignancies. In many cancers, ET-1/ET(A)R interaction induces proliferation, angiogenesis, antiapoptosis and resistance to chemotherapy.

The endothelin axis: a novel target for pharmacotherapy of female malignancies.

The endothelin axis (ET axis), comprising the three peptides endothelin (ET)-1, -2, -3 and their receptors ET(A)R and ET(B)R, is expressed in various cells and tissues. The biologically active ET-1 is formed by endothelin-converting enzyme (ECE) from inactive big-ET-1. ET-1 has emerged as an important peptide in a host of biological functions, including development, cellular proliferation, apoptosis and angiogenesis, thereby playing an important physiological and pathophysiological role.

Endocytosis of the dermatan sulfate proteoglycan decorin utilizes multiple pathways and is modulated by epidermal growth factor receptor signaling.

Human skin fibroblasts efficiently internalize the matrikine decorin by receptor-mediated endocytosis, however, very little is known about its intracellular trafficking routes up to lysosomal degradation. In an in vitro system measuring uptake and degradation of [(35)S]sulfate-labeled decorin, endocytosis was blocked by 46% when clathrin assembly/disassembly was inhibited using chlorpromazine. Pharmacological inhibition of EGF receptor signaling caused 34% reduction of decorin uptake, whereas inhibition of the IGF receptor had no effect.

On the role of endothelin-converting enzyme-1 (ECE-1) and neprilysin in human breast cancer.

Endothelin-1 (ET-1) and its receptors, ET(A)R and ET(B)R, are overexpressed in breast carcinomas. However, little is known about the relevance of endothelin-converting enzyme-1 (ECE-1) and ET-1 degrading neprilysin (NEP). In this study, expression of ECE-1 and NEP was determined in 600 breast cancer tissue samples by immunohistochemistry; staining results were correlated with clinicopathological parameters.

Therapeutic value of glycosaminoglycans in cancer.

Glycosaminoglycans are unbranched polysaccharides composed of repeating units of alternating uronic acids and amino sugars. Most glycosaminoglycans are covalently attached to core proteins to form proteoglycans. Posttranslational modifications result in specific motifs that bind to a large variety of ligands, thus regulating growth factor signaling, cellular behavior, inflammation, angiogenesis, and the proteolytic environment.
