In the COVID-19 pandemic, the concern about mask-harmful effects disturbed mask-adherence. However, it is not certain whether the masks cause cardiopulmonary overload. ⋯ In healthy volunteers, HR, RR, EtCO2 were increased, and SpO2 and walking distance were decreased in the short-term, light exercise performed with the surgical mask. Findings support the concern that masks may cause cardiopulmonary overload (Tab. 3, Fig. 1, Ref. 17).

The effect of poly(lactic‑co‑glycolic acid) (PLGA) on structure, degradation, drug release and mechanical properties of fibrin/pomegranate(F/POM)-based drug‑eluting scaffolds have been studied comprehensively.

The aim of this study was to determine the efficacy of pulse steroid therapy administered to patients critically ill with COVID-19 progressing into severe pneumonia. ⋯ Pulse steroid therapy does not shorten the duration of hospital stay, does not reduce the need for intubation and increases the risk of thrombosis by significantly increasing the level of D-dimer among patients critically and severely ill with COVID-19 (Tab. 4, Fig. 3, Ref. 20) Keywords: COVID-19, pulse steroid therapy, thrombosis, d-dimer, corticosteroid.

Observational Study
Simple ultrasound evaluation of fetal adrenal glands as a marker of imminent preterm birth: a preliminary report.
We present a simple 2D big ultrasound measurement of the fetal adrenal glands and their biometrical growth analysis highlighted as a potential preterm birth marker. ⋯ A simple 2D B-mode measurement of the fetal adrenal glands´ central zone growth can be applied as an additional marker in the prediction of true preterm delivery. The natural biometrical overall growth of the adrenal glands seems to be dependent on gestational age, whereas that of the central adrenal gland zone seems to be independent on gestational age (Tab. 3, Fig. 5, Ref. 26).

Bilateral finding of non-acute subdural hematomas (NASH) is less common compared to unilateral occurrence. The aim of this study was to evaluate results of surgical treatment of bilaterally treated bilateral NASH. ⋯ The laminar hematoma type and larger PHV were significant risk factors for the recurrence of bilateral NASH and worse neurological outcome. Larger PHCV and PV were significantly associated with hematoma recurrence (Tab. 7, Fig. 3, Ref. 24).
