Intrathecal chloroprocaine or hyperbaric prilocaine for ambulatory knee surgery? A prospective randomized study.

Purpose: The aim of this study was to compare intrathecal 1% chloroprocaine with 2% hyperbaric prilocaine in the setting of ambulatory knee arthroscopy. We hypothesized that complete resolution of the sensory block was faster with chloroprocaine.

Methods: Eighty patients scheduled for knee arthroscopy were included in this prospective randomized double-blind study.

The Role of Dectin-2 for Host Defense Against Disseminated Candidiasis.

Despite the fact that Candida albicans is an important human fungal pathogen and Dectin-2 is a major pattern recognition receptor for fungi, our knowledge regarding the role of Dectin-2 for the host defense against disseminated candidiasis is limited. Dectin-2 deficient (Dectin-2(-/-)) mice were more susceptible to systemic candidiasis, and the susceptibility was mirrored by an elevated fungal load in the kidneys that correlated with the presence of large inflammatory foci. Phagocytosis of Candida by the macrophages lacking the Dectin-2 receptor was moderately decreased, while production of most of the macrophage-derived cytokines from Dectin-2(-/-) mice with systemic candidiasis was decreased.

Fungal Chitin Induces Trained Immunity in Human Monocytes during Cross-talk of the Host with Saccharomyces cerevisiae.

The immune system is essential to maintain the mutualistic homeostatic interaction between the host and its micro- and mycobiota. Living as a commensal,Saccharomyces cerevisiaecould potentially shape the immune response in a significant way. We observed thatS.

Defective trained immunity in patients with STAT-1-dependent chronic mucocutaneaous candidiasis.

Patients with signal transducer and activator of transcription-1 (STAT1)-dependent chronic mucocutaneous candidiasis (CMC) and patients with STAT3-dependent hyper-immunoglobulin (Ig)E syndrome (HIES) display defects in T helper type 17 (Th17) cytokine production capacity. Despite this similar immune defect in Th17 function, they show important differences in the type of infections to which they are susceptible. Recently, our group reported differential regulation of STAT-1 and STAT-3 transcription factors during epigenetic reprogramming of trained immunity, an important host defence mechanism based on innate immune memory.

Antifungal innate immunity: recognition and inflammatory networks.

A large variety of fungi are present in the environment, among which a proportion colonizes the human body, usually without causing any harm. However, depending on the host immune status, commensals can become opportunistic pathogens that induce diseases ranging from superficial non-harmful infection to life-threatening systemic disease. The interplay between the host and the fungal commensal flora is being orchestrated by an efficient recognition of the microorganisms, which in turn ensures a proper balance between tolerance of the normal fungal flora and induction of immune defense mechanisms when invasion occurs.
