Few studies have been performed to investigate the association between vitamin D and respiratory problems in premature neonates. ⋯ The incidence of RDS, need for surfactants, and need for NIV in newborns with vitamin D insufficiency were higher than the neonates with normal levels.

Despite standard thromboprophylaxis, venous thrombosis is common in critically ill patients with COVID-19. The objective of this study was to evaluate deep venous thrombosis (DVT) incidence in patients with severe COVID-19 pneumonia with mechanical ventilation requirements under intermediate dose of chemical thromboprophylaxis (1 mg/kg/day of enoxaparin). This was a single-center, descriptive, cross-sectional study of prospectively collected data. ⋯ In 3 cases, DVT was catheter-related (2 in lower limbs and 1 in jugulo-subclavian confluent), 2 died during follow-up due to acute respiratory distress syndrome (ARDS) complications without thrombotic events or major bleeding. All thrombotic events were asymptomatic. In our series of patients with moderate/severe COVID-19 ARDS, DVT incidence was 10.9% under thromboprophylaxis with intermediate dose (1 mg/kg/ day) of enoxaparin.

The pathomechanisms of hypoxemia and treatment strategies for type H and type L acute respiratory distress syndrome (ARDS) in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-induced coronavirus disease 2019 (COVID-19) have not been elucidated. ⋯ Right-to-left shunts and high VA/Q ratios caused by lung microvascular thrombosis contribute to hypoxemia in type H and L ARDS, respectively. D-dimer monitoring-based anticoagulation therapy may prevent the progression to and/or worsening of ARDS in COVID-19 patients.
