Potential roles of FGF5 as a candidate therapeutic target in prostate cancer.

Fibroblast growth factor (FGF) is a secreted ligand that is widely expressed in embryonic tissues but its expression decreases with age. In the developing prostate, FGF5 has been proposed to interact with the Hedgehog (Hh) signaling pathway to guide mitogenic processes. In the adult prostate, the FGF/FGFR signaling axis has been implicated in prostate carcinogenesis, but focused studies on FGF5 functions in the prostate are limited. Functional studies completed in other cancer models point towards FGF5 overexpression as an oncogenic driver associated with stemness, metastatic potential, proliferative capacity, and increased tumor grade. In this review, we explore the significance of FGF5 as a therapeutic target in prostate cancer (PCa) and other malignancies; and we introduce a potential route of investigation to link FGF5 to benign prostatic hyperplasia (BPH). PCa and BPH are two primary contributors to the disease burden of the aging male population and have severe implications on quality of life, psychological wellbeing, and survival. The development of new FGF5 inhibitors could potentially alleviate the health burden of PCa and BPH in the aging male population.

[Risk stratification through implementation and evaluation of a COVID-19 score : A retrospective diagnostic study]. / Risikostratifizierung durch Implementierung und Evaluation eines COVID-19-Scores : Eine retrospektive Diagnostikstudie.

BACKGROUND: The clinical manifestation of COVID-19 is nonspecific and varies greatly, which makes it more difficult to discriminate from other (virus) infections. Neither individual findings nor combinations of findings are specific enough to be able to diagnose COVID-19 with a high degree of certainty. The goal was to identify patients in the emergency department, who are at risk for COVID-19 disease, early by using a score, so that they could be isolated pre-emptively. METHOD: Development and implementation of a symptom-based COVID-19 score based on a multicentric retrospective evaluation in three German emergency departments from 9 March until 30 April 2020 of patients suspected of having COVID-19 and subsequent SARS-CoV­2 PCR testing. RESULTS: The study population included 697 patients and 9.4% of these patients were diagnosed with COVID-19 infection. A COVID-19 score of ≥5 points was associated with a significantly increased likelihood of illness. The sensitivity of the score was 98.4% with a moderate specificity of 48.3%. DISCUSSION: The score, which is easy to obtain during the initial assessment, supports the assessment of the pretest probability for a COVID-19 infection as part of the risk stratification and can influence the treatment pathway in terms of pre-emptive isolation, PCR testing and other treatment options at an early stage. Due to the nonspecific symptoms of the disease; however, it must be accepted that the goal of high sensitivity results in a relatively low specificity of the score.

A case study of teaching social responsibility to doctoral students in the climate sciences.

The need to make young scientists aware of their social responsibilities is widely acknowledged, although the question of how to actually do it has so far gained limited attention. A 2-day workshop entitled "Prepared for social responsibility?" attended by doctoral students from multiple disciplines in climate science, was targeted at the perceived needs of the participants and employed a format that took them through three stages of ethics education: sensitization, information and empowerment. The workshop aimed at preparing doctoral students to manage ethical dilemmas that emerge when climate science meets the public sphere (e.g., to identify and balance legitimate perspectives on particular types of geo-engineering), and is an example of how to include social responsibility in doctoral education. The paper describes the workshop from the three different perspectives of the authors: the course teacher, the head of the graduate school, and a graduate student. The elements that contributed to the success of the workshop, and thus make it an example to follow, are (1) the involvement of participating students, (2) the introduction of external expertise and role models in climate science, and (3) a workshop design that focused on ethical analyses of examples from the climate sciences.
