Chemotherapy has a significant but transient effect on olfactory and gustatory function, possibly causing reduced appetite, a low energy intake, and weight loss. Additional spices and flavoring may compensate for this diminished chemosensory function, enhancing patient compliance and quality of life.

The time of pregnancy, birth, and lactation, is characterized by numerous specific alterations in several systems of the maternal body. Peripartum-associated changes in physiology and behavior, as well as their underlying molecular mechanisms, have been the focus of research since decades, but are still far from being entirely understood. Also, there is growing evidence that pregnancy and lactation are associated with a variety of alterations in neural plasticity, including adult neurogenesis, functional and structural synaptic plasticity, and dendritic remodeling in different brain regions. All of the mentioned changes are not only believed to be a prerequisite for the proper fetal and neonatal development, but moreover to be crucial for the physiological and mental health of the mother. The underlying mechanisms apparently need to be under tight control, since in cases of dysregulation, a certain percentage of women develop disorders like preeclampsia or postpartum mood and anxiety disorders during the course of pregnancy and lactation. This review describes common peripartum adaptations in physiology and behavior. Moreover, it concentrates on different forms of peripartum-associated plasticity including changes in neurogenesis and their possible underlying molecular mechanisms. Finally, consequences of malfunction in those systems are discussed.

Ductoscopy is gaining increased importance in the diagnosis of nipple discharge of unclear origin and intraductal proliferation. For this reason we compared its diagnostic value and feasibility to standard diagnostic methods. Material and Methods: Ductoscopy was compared to mammography, galactography, sonography, magnetic resonance imaging (MRI), nipple smear, fine needle aspiration cytology (FNAC), and high-speed core biopsy; feasibility, sensitivity, and specificity were investigated for each method. Results: 71 ductoscopies were evaluated, which were followed up by open biopsies. Here, 3 invasive and 8 ductal carcinomas in situ were found, as well as 3 atypical ductal hyperplasias, 44 papillomas/papillomatoses, and 13 benign findings. Feasibility of ductoscopy was in this series 100%. Duct sonography showed the highest sensitivity (67.3%), followed by MRI (65.2%), galactography (56.3%), ductoscopy (55.2%), and FNAC (51.9%). The highest specificity was shown by FNAC, core biopsy, and galactography (each 100.0%), followed by mammography (92.3%), nipple smear (77.8%), ductoscopy, and duct sonography (each 61.5%); the lowest specificity was displayed by MRI (25.0%). Conclusion: The results confirm that ductoscopy can be performed within the same range of sensitivity and specificity as other techniques. In order to make conclusive statements about ductoscopy, especially in order to precisely define the indications for this method, a prospective multicenter study was initiated.

SCM with NAC-skin conservation may be performed according to total mastectomy indications if an intraoperative frozen section (and the corresponding HE histopathology) of the tissue next to the nipple-areola skin is free of tumor. The remaining contraindications for SCM are: extensive tumor involvement of the skin, inflammatory breast cancer, and a clinically suspicious nipple.

BackgroundPooled human platelet lysate (pHPL) is an efficient alternative to xenogenic supplements for ex vivo expansion of mesenchymal stem cells (MSCs) in clinical studies. Currently, porcine heparin is used in pHPL-supplemented medium to prevent clotting due to plasmatic coagulation factors. We therefore searched for an efficient and reproducible medium preparation method that avoids clot formation while omitting animal-derived heparin.MethodsWe established a protocol to deplete fibrinogen by clotting of pHPL in medium, subsequent mechanical hydrogel disruption and removal of the fibrin pellet. After primary culture, bone-marrow and umbilical cord derived MSCs were tested for surface markers by flow cytometry and for trilineage differentiation capacity. Proliferation and clonogenicity were analyzed for three passages.ResultsThe proposed clotting procedure reduced fibrinogen more than 1000-fold, while a volume recovery of 99.5 % was obtained. All MSC types were propagated in standard and fibrinogen-depleted medium. Flow cytometric phenotype profiles and adipogenic, osteogenic and chondrogenic differentiation potential in vitro were independent of MSC-source or medium type. Enhanced proliferation of MSCs was observed in the absence of fibrinogen but presence of heparin compared to standard medium. Interestingly, this proliferative response to heparin was not detected after an initial contact with fibrinogen during the isolation procedure.ConclusionsHere, we present an efficient, reproducible and economical method in compliance to good manufacturing practice for the preparation of MSC media avoiding xenogenic components and suitable for clinical studies.Electronic supplementary materialThe online version of this article (doi:10.1186/s12967-015-0717-4) contains supplementary material, which is available to authorized users.
