[Evidence for the extent and oncological benefit of lymphadenectomy for pancreatic cancer].

Pancreatic cancer is usually diagnosed at a late stage and is characterized by early systemic metastases, which can also be present in the form of micrometastases that are not primarily visible. Lymphatic metastases in pancreatic cancer are common. The extent of lymph node removal (lymphadenectomy, LAD) in pancreatic cancer is defined in the guidelines of the Association of the Scientific Medical Societies in Germany (AWMF) and according to currently available data has more diagnostic and prognostic relevance than therapeutic relevance; however, within the framework of modern multimodal treatment algorithms, radical surgery is the most relevant of all components of multimodal treatment with LAD playing an important role.

University of Marburg, Marburg, Germany.
Background: Total knee arthroplasty (TKA) is one of the most common orthopaedic procedures and the number of patients which undergo TKA will continue to rise in the coming years. Consecutively, the number of necessary revision surgeries will increase. One of the main reasons for revision surgery is aseptic loosening because of a so-called stress-shielding effect.

Department of Orthopedics and Trauma Surgery, BG University Hospital, Bochum, Germany.
Background: So-called scores are a frequently used evaluation system in clinical examinations to assess the function or limitations of a joint such as the shoulder. However, research indicates that these general scores often have limited validity for specific patient groups, such as athletes. Known as a demanding patient population, athletes have unique needs.

From the 1950s to the present, the main tool for obtaining fungal industrial producers of secondary metabolites remains the so-called classical strain improvement (CSI) methods associated with multi-round random mutagenesis and screening for the level of target products. As a result of the application of such techniques, the yield of target secondary metabolites in high-yielding (HY) strains was increased hundreds of times compared to the wild-type (WT) parental strains. However, the events that occur at the molecular level during CSI programs are still unknown.

A primary pull-through for Hirschsprung's disease (HD) requires confirmation of normal ganglionic bowel by intraoperative biopsies to determine the level of resection. Despite this, aganglionic bowel that is not fully resected (so-called "transition zone pull-throughs") is reported in 15%-19% of patients. We hypothesize that this may result from insufficient biopsies sent for intraoperative diagnosis.
