The coordination compounds of the trivalent lanthanide ions (Ln(III)) have unique photophysical properties. Ln(III) excitation is usually performed through a light-harvesting antenna. To enable Ln(III)-based emitters to reach their full potential, an understanding of how complex structure affects sensitization and quenching processes is necessary.

We present a case of a 38+1 weeks pregnant patient (G1P0) with a proven COVID-19 infection, who was planned for induction of labour because of pre-existent hypertension, systemic lupus erythematosus, respiratory problem of coughing and mild dyspnoea without fever during the COVID-19 pandemic in March 2020. To estimate the risk of vertical transmission of Severe Acute Respiratory Syndrome CoronaVirus 2 (SARS-CoV-2) during labour and delivery, we collected oropharyngeal, vaginal, urinary, placental and neonatal PCRs for SARS-CoV-2 during the period of admission. All PCRs, except for the oropharyngeal, were negative and vertical transmission was not observed.

Objective: To assess the effectiveness of curettage versus expectant management in women with an incomplete evacuation of the uterus after misoprostol treatment for first trimester miscarriage.

Study Design: We conducted a multicenter cohort study alongside a randomized clinical trial (RCT) between June 2012 until July 2014. 27 Dutch hospitals participated.

Study Question: Is curettage more effective than expectant management in case of an incomplete evacuation after misoprostol treatment for first trimester miscarriage?

Summary Answer: Curettage leads to a higher chance of complete evacuation but expectant management is successful in at least 76% of women with an incomplete evacuation of the uterus after misoprostol treatment for first trimester miscarriage.

What Is Known Already: In 5-50% of the women treated with misoprostol, there is a suspicion of incomplete evacuation of the uterus on sonography. Although these women generally have minor symptoms, such a finding often leads to additional curettage.
