Randomized Controlled Trial Multicenter Study Clinical Trial
Efficacy and safety of intravenous levosimendan compared with dobutamine in severe low-output heart failure (the LIDO study): a randomised double-blind trial.
Levosimendan, a novel calcium sensitiser, improves myocardial contractility without causing an increase in myocardial oxygen demand. We compared the effects of levosimendan and dobutamine on haemodynamic performance and clinical outcome in patients with low-output heart failure. ⋯ In patients with severe, low-output heart failure, levosimendan improved haemodynamic performance more effectively than dobutamine. This benefit was accompanied by lower mortality in the levosimendan group than in the dobutamine group for up to 180 days.

Obstructive sleep apnoea is a disease of increasing importance because of its neurocognitive and cardiovascular sequelae. Abnormalities in the anatomy of the pharynx, the physiology of the upper airway muscle dilator, and the stability of ventilatory control are important causes of repetitive pharyngeal collapse during sleep. ⋯ The surges in hypoxaemia, hypercapnia, and catecholamine associated with this disorder have now been implicated in development of hypertension, but the association between obstructive sleep apnoea and myocardial infarction, stroke, and congestive heart failure is not proven. Continuous positive airway pressure, the treatment of choice for obstructive sleep apnoea, reduces sleepiness and improves hypertension.

Most maternity units have good practice protocols, advising that after stillbirth parents should be encouraged to see and hold their dead infant. Our aim was to assess whether adherence to these protocols is associated with measurably beneficial effects on the psychological health of mother and next-born child. This study forms part of a wider case-control study of the psychological effects of stillbirth. ⋯ Our findings do not support good-practice guidelines, which state that failure to see and hold the dead child could have adverse effects on parents' mourning.
