Impairments in facial expression recognition in patients with euthymic bipolar disorders using the facial emotions recognition test.

Background: Patients with bipolar disorders (BD) have significant impairments in Facial Expression Recognition (FER), an essential social skill for effective social interactions. While the Facial Emotions Recognition Test, 54 photographs by Gaudelus (TREF-54g) has been used in patients with schizophrenia, no study has evaluated FER using this test in BD patients. The TREF-54g meets the International Society for Bipolar Disorders (ISBD) criteria for assessing FER.

Characteristics of patients who are initiated on long-acting buprenorphine (Buvidal®) in France: A retrospective cross-sectional study.

Aim: The long-acting buprenorphine Buvidal® is a recent type of opioid agonist treatment (OAT) used for opioid use disorder (OUD). It was initially suggested to preferentially use Buvidal® for specific OUD populations, including people in prison, or patients in recovery and on sublingual buprenorphine. We conducted a national study to examine whether the profile of patients treated with Buvidal® in France matched these initial recommendations.

A population of luminous accreting black holes with hidden mergers.

Major galaxy mergers are thought to play an important part in fuelling the growth of supermassive black holes. However, observational support for this hypothesis is mixed, with some studies showing a correlation between merging galaxies and luminous quasars and others showing no such association. Recent observations have shown that a black hole is likely to become heavily obscured behind merger-driven gas and dust, even in the early stages of the merger, when the galaxies are well separated (5 to 40 kiloparsecs).
