Injury characteristics in Norwegian male professional football: A comparison between a regular season and a season in the pandemic.

The Coronavirus Disease-19 (COVID-19) pandemic forced the Norwegian male premier league football season to reschedule, reducing the fixture calendar substantially. Previous research has shown that a congested match schedule can affect injury rates in professional football. Therefore, we aimed to investigate whether the Norwegian premier league teams suffered more injuries in the more match congested 2020 season than in the regular 2019-season.

Echo-encephalographic study of ventricular dilatation after subarachnoid hemorrhage, with special reference to the effect of antifibrinolytic treatment.

Echo-encephalographic examinations were performed in 144 patients after subarachnoid hemorrhage. Ninety-three of the patients received antifibrinolytic treatment (AMCA). The width of the third ventricle could be measured in all the patients, and lateral ventricle measurements were obtained in 94 patients.

Local haemostasis in brain tumours.

The thromboplastic activity and the fibrinolytic activity were examined in 7 human meningiomas and 6 gliomas obtained at neurosurgery. Two different haemostatic patterns emerged, meningiomas having lower thromboplastic and higher fibrinolytic activity than that of gliomas. This difference might help to explain the better haemostatic capacity of gliomas during and after operation than that of meningiomas.
