Hydroxychloroquine with azithromycin in patients hospitalized for mild and moderate COVID-19.

Objectives: To assess the efficacy of hydroxychloroquine in combination with azithromycin in terms of clinical and biochemical outcomes in adult patients with COVID-19 hospitalized for acute respiratory distress syndrome (ARDS), and to describe the occurrence of adverse events.

Method: Retrospective comparative study, based in a quaternary private hospital in Rio de Janeiro, Brazil, involving 193 adult patients hospitalized for mild and moderate COVID-19 related ARSD, analyzing treatment efficacy based on clinical and biochemical outcomes.

Results: The active group comprised 101 (52.

Intracoronary stem-cell injection after myocardial infarction: microcirculation sub-study.

Background: The injection of stem cells in the context of acute myocardial infarction (AMI) has been tested almost exclusively by anterograde intra-arterial coronary (IAC) delivery. The retrograde intravenous coronary (IVC) delivery may be an additional route.

Objective: To compare the cell distribution and retention pattern in the anterograde and retrograde routes.

Effects of hormone replacement therapy or raloxifene on ambulatory blood pressure and arterial stiffness in treated hypertensive postmenopausal women.

The administration of oral raloxifene in 30 postmenopausal hypertensive women was evaluated to demonstrate its effect on arterial stiffness. Casual and ambulatory blood pressure (BP) and pulse-wave velocity (PWV) data were obtained before and after patients received raloxifene, estrogen-progestin replacement therapy, or placebo in a randomized crossover study. It was shown that the 2 therapies decreased BP and carotid-femoral PWV, and the effect of raloxifene on vascular compliance was independent of the effects on BP.
