Lithium Use During Pregnancy in 14 Countries.

Importance: In pregnancy, the benefits of lithium treatment for relapse prevention in psychiatric conditions must be weighed against potential teratogenic effects. Currently, there is a paucity of information on how and when lithium is used by pregnant women.

Objective: To examine lithium use in the perinatal period.

Fungal biomarkers in HIV-associated disseminated histoplasmosis: a multicenter diagnostic accuracy study on the Guiana shield.

Background: Diagnosis of HIV-associated histoplasmosis remains challenging. Our objective was to compare the performances of (1→3)-β-D-Glucan (BDG) and Aspergillus galactomannan (GM) antigen for the diagnosis of HIV-associated histoplasmosis.

Methods: We performed a diagnostic accuracy study using frozen primary serum specimens issued from consecutive hospitalized people living with HIV (PLWH) and blindly tested for BDG and GM using Fungitell® and PlateliaTM Aspergillus, respectively.

Activity of botulinum neurotoxin X and its structure when shielded by a non-toxic non-hemagglutinin protein.

Botulinum neurotoxins (BoNTs) are the most potent toxins known and are used to treat an increasing number of medical disorders. All BoNTs are naturally co-expressed with a protective partner protein (NTNH) with which they form a 300 kDa complex, to resist acidic and proteolytic attack from the digestive tract. We have previously identified a new botulinum neurotoxin serotype, BoNT/X, that has unique and therapeutically attractive properties.
