SARS-CoV-2 screening strategies for returning international travellers: Evaluation of a rapid antigen test approach.

Background: International travel poses the risk of importing SARS-CoV-2 infections and introducing new viral variants into the country of destination. Established measures include mandatory quarantine with the opportunity to abbreviate it with a negative rapid antigen test (RAT).

Methods: A total of 1,488 returnees were tested for SARS-CoV-2 with both PCR and RAT no earlier than 5 days after arrival.

Two cases of airport-associated falciparum malaria in Frankfurt am Main, Germany, October 2019.

Two cases of presumably airport-acquired falciparum malaria were diagnosed in Frankfurt in October 2019. They were associated with occupation at the airport, and parasites from their blood showed genetically identical microsatellite and allele patterns. Both had severe malaria.

Dynamic cerebral autoregulation in pregnancy and the risk of preeclampsia.

Preeclampsia may affect severely the cerebral circulation leading to impairment of cerebral autoregulation, edema, and ischemia. It is not known whether impaired autoregulation occurs before the clinical onset of preeclampsia, and whether this can predict the occurrence of preeclampsia. Seventy-two women at 25 to 28 weeks of gestation were studied.

Cerebellar and cerebral autoregulation in migraine.

Background And Purpose: Silent ischemic brain lesions frequently occur in migraine with aura and are most often located in cerebellar border zones. This may imply an impairment of cerebellar blood flow autoregulation. This study investigated the characteristics of interictal cerebellar autoregulation in migraine with and without aura.
