[Impact of prolonged second stage of labor on perinatal morbidity : what is our experience ?].

Objective: the management of the second stage of labor and its optimal duration are controversial, particularly for nulliparous women. Our aim is to analyze the impact of a prolonged second stage on perinatal morbidity in our institution.

Material And Methods: this is a retrospective study conducted in the University Hospital of Liège (Belgium) from January to July 2019.

[Heredity and cancer].

A personal or family history of cancer has now become the primary cause of genetic consultations. In recent years, various genes have been identified that are associated with a more or less marked genetic predisposition to the development of cancers. The syndrome associated with the hereditary risk of breast and ovarian cancer and the Lynch syndrome are the most frequent ones, but there are many other, much less common, situations associated with familial cancer risk.

Development and validation of a predictive model to determine the level of care in patients confirmed with COVID-19.

Background: The COVID-19 pandemic has imposed significant challenges on hospital capacity. While mitigating unnecessary crowding in hospitals is favourable to reduce viral transmission, it is more important to prevent readmissions with impaired clinical status due to initially inappropriate level of care. A validated predictive tool to assist clinical decisions for patient triage and facilitate remote stratification is of critical importance.

Clinical decision support tool for diagnosis of COVID-19 in hospitals.

Background: The coronavirus infectious disease 19 (COVID-19) pandemic has resulted in significant morbidities, severe acute respiratory failures and subsequently emergency departments' (EDs) overcrowding in a context of insufficient laboratory testing capacities. The development of decision support tools for real-time clinical diagnosis of COVID-19 is of prime importance to assist patients' triage and allocate resources for patients at risk.

Methods And Principal Findings: From March 2 to June 15, 2020, clinical patterns of COVID-19 suspected patients at admission to the EDs of Liège University Hospital, consisting in the recording of eleven symptoms (i.
