The estimation of ion-exchange chromatography model parameters is crucial to enable efficient model-assisted biopharmaceutical downstream process development. Model calibration methods can be hindered by model limitations combined with parameter correlations, leading to time-consuming repeated parameter estimations. While Steric Mass Action isotherm estimation methods exist, there is a need for a systematic approach to estimate model parameters for an emerging Colloidal Particle Adsorption (CPA) model proposed by Briskot et al.

Background: Medical staff are regularly confronted with workplace violence (WPV), which poses a threat to the safety of both staff and patients. Structured de-escalation training (DET) for Emergency Department (ED) staff has been shown to positively affect the reporting of WPV incidents and possibly reduce its impact. This study aimed to describe the development of incidence rates, causes, means, targets, locations, responses, and the time of WPV events.

Article Synopsis
  • The study examines outcomes of two pregnancies with suspected preeclampsia, focusing on the diagnostic value of clinical signs and the sFlt-1 to PlGF ratio in predicting adverse outcomes.
  • Out of 1928 screened patients, 1117 were included, with 84 women having suspected preeclampsia in both pregnancies.
  • Results show that adverse outcome prevalence decreased from 27.4% in the first to 17.9% in the second pregnancy, and the first pregnancy's sFlt-1/PlGF ratio did not predict outcomes in the second pregnancy, indicating these markers are short-term assessment tools.

Molluscs are intermediate hosts for several parasites. The recognition processes, required to evade the host's immune response, depend on carbohydrates. Therefore, the investigation of mollusc glycosylation capacities is of high relevance to understand the interaction of parasites with their host.

Article Synopsis
  • Anemia is a serious health concern that leads to increased morbidity and mortality, and this study investigates how preoperative hemoglobin levels relate to in-hospital mortality, comparing men and women.
  • Analyzing data from over 842,000 surgical patients in Germany, the researchers found that lower preoperative hemoglobin levels significantly increased the odds of in-hospital mortality.
  • The study identified a hemoglobin threshold of 10.5 g/dL, indicating that below this level, women face a higher risk of death compared to men, emphasizing the need for tailored anemia management to ensure equitable patient care.
