Effectiveness of therapeutic heparin versus prophylactic heparin on death, mechanical ventilation, or intensive care unit admission in moderately ill patients with covid-19 admitted to hospital: RAPID randomised clinical trial.

Objective: To evaluate the effects of therapeutic heparin compared with prophylactic heparin among moderately ill patients with covid-19 admitted to hospital wards.

Design: Randomised controlled, adaptive, open label clinical trial.

Setting: 28 hospitals in Brazil, Canada, Ireland, Saudi Arabia, United Arab Emirates, and US.

Heparin for Moderately Ill Patients with Covid-19.

Background: Heparin, in addition to its anticoagulant properties, has anti-inflammatory and potential anti-viral effects, and may improve endothelial function in patients with Covid-19. Early initiation of therapeutic heparin could decrease the thrombo-inflammatory process, and reduce the risk of critical illness or death.

Methods: We randomly assigned moderately ill hospitalized ward patients admitted for Covid-19 with elevated D-dimer level to therapeutic or prophylactic heparin.

Mirror finger patterns of apparent monozygotic twins and sib pairs with Schizophrenia.

Background: Although mirror images are noted in some twins, no such reports are available for twins and subjects with schizophrenia.

Aim: The study was to assess the occurrence of mirror image finger patterns in apparent monozygotic twins with schizophrenia. Another objective was to elucidate these characteristics among sib pairs with schizophrenia for comparison with those of the twins.
