The prognostic role of echocardiographic right ventricular (RV) dysfunction for predicting mortality in patients with acute pulmonary embolism and a preserved systemic arterial pressure remains controversial. ⋯ Among patients with pulmonary embolism who present with a systolic arterial pressure greater than or equal to 90 mm Hg, echocardiographic RV hypokinesis is an independent predictor of early death.

Clinical and Imaging Signs of Spondyloarthritis in First-Degree Relatives of HLA-B27-Positive Ankylosing Spondylitis Patients: The Pre-Spondyloarthritis (Pre-SpA) Cohort Study.
To investigate whether seemingly healthy first-degree relatives of patients with ankylosing spondylitis (AS) have clinical, laboratory, or imaging features of spondyloarthritis (SpA). ⋯ A substantial proportion of seemingly healthy first-degree relatives of HLA-B27-positive AS patients have clinical and/or imaging abnormalities suggestive of SpA. Thirty-three percent could be classified as having SpA. Further follow-up will show which first-degree relatives will develop clinically manifest SpA.

Nonadherence to statin therapy: discontinuation after a single fill.
Adherence to statin medications is known to be suboptimal. What is less known is the rate of discontinuation immediately after therapy has been initiated. The primary objective of this study was to determine what proportion of nonadherence in the first year of statin therapy was due to discontinuation after a single fill. ⋯ Immediate discontinuation after a single fill contributes disproportionately to statin nonadherence. This suggests an important time to prevent nonadherence is within the first month of treatment initiation.

Review[Cardiac insufficiency: acute right heart failure].
Acute right heart failure (RHF) is a frequent and severe complication during perioperative and intensive care treatment in intensive care units (ICUs). The most common causes are pulmonary hypertension, left heart failure, pulmonary embolism, sepsis, acute lung injury (ALI) and thoracosurgical procedures. ⋯ Although many drugs are available for the treatment of RHF, randomized trials for this setting are still missing. This article gives an overview of aetiology and pathogenesis of RHF and reviews the diagnostic and therapeutic interventions currently available for providers in anaesthesiology and critical care.

Vestibularly evoked climbing-fiber responses modulate simple spikes in rabbit cerebellar Purkinje neurons.
The nodulus receives a primary vestibular afferent input from the ipsilateral labyrinth and a vestibularly related climbing-fiber input originating from the contralateral labyrinth. Previously we demonstrated that increased discharge of vestibularly evoked climbing-fiber responses (CFRs) in nodular Purkinje cells was correlated with decreased discharge of simple spikes (SSs). This left unresolved the question of whether vestibularly evoked antiphasic behavior of CFRs and SSs reflects a common neural mechanism or the activation of two separate parallel pathways. ⋯ SSs continued to respond to contralateral roll-tilt even when the primary vestibular afferent mossy-fiber pathway was destroyed by the unilateral labyrinthectomy. Although the discharge of SSs recorded in the contralateral uvula-nodulus was increased by contralateral roll-tilt, this modulation was reduced relative to that observed in Purkinje cells recorded in the ipsilateral uvula-nodulus. We conclude that vestibularly evoked CFRs caused the modulation of SS discharge.
