Efficacy of a vein visualisation device for facilitating peripheral venous line placement in adult patients with sickle cell disease: A randomised clinical trial.

Background: Intravenous (IV) access is often required for the treatment of vaso-occlusive crises in patients with sickle cell disease, but can be particularly challenging due to recurrent venous damage. The AccuVein® device, uses near-infrared light technology to visualise veins for easier venepuncture.

Methods: A randomised, controlled trial of the efficacy of the AccuVeinAV400® device in the replacement of peripheral venous lines during a vaso-occlusive crisis was conducted at two centres in France.

Ubiquitin and Ubiquitin-Like Modifications in Organelle Stress Signaling: Ub, Ub, Ub, Ub, Stayin' Alive, Stayin' Alive.

Due to various intracellular and external cues, cellular organelles are frequently stressed in both physiological and pathological conditions. Sensing these stresses initiates various signaling pathways which may lead to adaptation of the stressed cells or trigger its their death. At the unicellular level, this stress signaling involves a crosstalk between different organelles.

Assessment of fatigue in adult patients with sickle cell disease: Use of the functional assessment of chronic illness therapy-Fatigue (FACIT-fatigue) questionnaire.

Few studies have used validated scales to assess the intensity and determinants of fatigue, a major symptom of sickle cell disease (SCD). We aimed to assess the level of basal fatigue in adult patients with SCD, using the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue) questionnaire. We prospectively included 102 stable adult outpatients with SCD over 2 months, who answered the FACIT-Fatigue (ranging from 0 (worst imaginable fatigue) to 52 (no fatigue)) and reported on the intensity of fatigue and its impact on quality of life.

Assessing Phagocytosis of Cryptococcus neoformans Cells in Human Monocytes or the J774 Murine Macrophage Cell Line.

Monocyte/macrophage cells play a central role in innate immunity against C. neoformans and C. gattii, species known to cause human disease.
