The performance of diagnostic tests crucially depends on the disease prevalence, test sensitivity, and test specificity. However, these quantities are often not well known when tests are performed outside defined routine lab procedures which make the rating of the test results somewhat problematic. A current example is the mass testing taking place...

Background The majority of breast cancer patients are severely psychologically affected by breast cancer diagnosis and subsequent therapeutic procedures. The COVID-19 pandemic and associated restrictions on public life have additionally caused significant psychological distress for much of the population. It is therefore plausible that breast cance...
Article
Zusammenfassung Es gibt bislang nur wenige Studien, die den Einfluss einer streng kohlenhydratreduzierten, sehr fettreichen, sog. „ketogenen“ Kost auf den Verlauf einer Krebserkrankung untersuchten. Da eine solche Kostform längerfristig Schwierigkeiten bei der Compliance zu Hause bereitet, ist ein supportiver Therapieansatz evtl. sinnvoller, weil e...

Background The onset of mental illness such as depression and anxiety disorders in pregnancy and postpartum period is common. The coronavirus induced disease 2019 (COVID-19) pandemic and the resulting public policy responses represent an exceptional situation worldwide and there are hints for adverse psychosocial impact, hence, the study of psychol...

Breast cancer (BC) patients often ask for a healthy diet. Here, we investigated a healthy standard diet (SD), a low carb diet (LCD), and a ketogenic diet (KD) for BC patients during the rehabilitation phase. KOLIBRI was an open-label non-randomized one-site nutritional intervention trial, combining inpatient and outpatient phases for 20 weeks. Fema...

Article
Introduction: Expression of fibroblast activation protein (FAP) has been detected in activated fibroblasts participating in injury response, fibrotic and inflammatory conditions, and tumorigenesis. Human endometrium is equally characterized by rapid tissue remodeling events due to the reproductive tasks comprising the activity of proteolytic enzym...

Background: Obesity and low muscle mass are associated with worse outcomes of breast cancer patients. We conducted a controlled trial to study the impact of a ketogenic diet (KD) based on natural foods versus an unspecified standard diet (SD) on body composition in breast cancer patients undergoing radiotherapy. Methods: Patients with non-metast...

Background: Breast Cancer (BC) patients often ask for a healthy diet. Here, we compared three different diets which could support BC patients during the rehabilitation process: a healthy standard diet (SD), a low carb diet (LCD) and a ketogenic diet (KD). Patients and Methods: KOLIBRI was a one-site nutritional intervention trial, combining inpatie...

Objective: In proliferative retinopathies, complications derived from neovascularization cause blindness. During early disease, pericyte's apoptosis contributes to endothelial dysfunction and leakage. Hypoxia then drives VEGF (vascular endothelial growth factor) secretion and pathological neoangiogenesis. Cardiac ANP (atrial natriuretic peptide) c...
Article
Background/objectives: BRCA mutation carriers and women at high risk of breast/ovarian cancer are faced with the intricate question to opt for prophylactic surgeries and/or a periodic screening. The aim of this study was therefore to identify objective and emotional factors that have an impact on the decision-making process. Methods: Ninety-five...
Article
Wenige Ernährungsmodifikationen werden derzeit so kontrovers diskutiert wie die ketogene Diät (KD). Hier erörtern wir die wissenschaftlichen Hintergründe dafür, dass sich für klinisch tätige Gynäkologen eine intensive Auseinandersetzung mit dieser supportiven (Ernährungs‑)Therapie lohnt, und erläutern die korrekte Durchführung der KD, um Nebenwirku...
Article
Merkel cell carcinoma (MCC), an aggressive neuroendocrine skin tumor, is a polyomavirus‐induced human cancer. To study the causal relationship of MCC carcinogenesis with the integrated Merkel cell polyomavirus (MCPyV) in detail, well‐characterized MCC cell lines are needed. Consequently, in the current study we established and characterized six MCP...

Background: Ketogenic diets (KDs) or short-term fasting are popular trends amongst supportive approaches for cancer patients. Beta-hydroxybutyrate (3-OHB) is the main physiological ketone body, whose concentration can reach plasma levels of 2-6 mM during KDs or fasting. The impact of 3-OHB on the biology of tumor cells described so far is contradi...
Article
Eine ketogene Ernährung mit einem sehr hohen Fettanteil und einer Verknappung von Glukose zeigt tierexperimentell günstige Effekte auf Tumorwachstum und Überleben. In der humanen Krebstherapie deuten sich positive Wirkungen der ketogenen Diät in der Kombination mit Strahlen- und Chemotherapie an.

Objective Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women, involving hyperandrogenaemia and insulin resistance. Treatment options include dexamethasone, as well as the off-label use of metformin. To evaluate the impact of those drugs on cyclic changes in endometrial development, we tested possible effects of metformi...

Background Fermented wheat germ extract (FWGE) sold under the trade name Avemar exhibits anticancer activity in vitro and in vivo. Its mechanisms of action are divided into antiproliferative and antimetabolic effects. Its influcence on cancer cell metabolism needs further investigation. One objective of this study, therefore, was to further elucida...

Background: Currently ketogenic diets (KDs) are hyped as an anti-tumor intervention aimed at exploiting the metabolic abnormalities of cancer cells. However, while data in humans is sparse, translation of murine tumor models to the clinic is further hampered by small sample sizes, heterogeneous settings and mixed results concerning tumor growth re...
Article
Rationale: In patients after acute myocardial infarction (AMI), the initial extent of necrosis and inflammation determine clinical outcome. One early event in AMI is the increased cardiac expression of atrial (ANP) and B-type natriuretic peptides (BNP), their plasma levels correlating with severity of ischemia. It was shown that NPs, via their cGM...
Article
Hintergrund: Der Stoffwechsel maligner Tumoren unterscheidet sich von dem gesunder Gewebe oftmals durch eine gesteigerte Rate an Glukoseumsatz. In den letzten Jahren stieg das Interesse an einem diätischen Therapieansatz, der das Ziel verfolgt, mithilfe einer Kohlenhydrateinschränkung diese metabolische Besonderheit von Tumorzellen auszunutzen. Prä...

Problem: Human pregnancy needs a remarkable local immune tolerance toward the conceptus. Myeloid-derived suppressor cells (MDSC) are important players promoting cancer initiation and progression by suppressing T-cell functions and thus inducing immune tolerance. Therefore, MDSC were expected within decidua. Methods: Subpopulations of CD33(+) imm...
Article
During healthy pregnancy, a distinct but limited invasion of trophoblast cells into the uterus occurs. In contrast, excessive trophoblast invasion is associated with placental choriocarcinoma (CC). Overexpression of the cytoskeletal protein LASP-1 was shown to contribute to cancer aggressiveness. Here, the yet unknown role of LASP-1 in CC cells is...
