Variability in the diagnosis and reporting of metaplastic breast carcinoma: results of an international survey.

Aims: Metaplastic breast carcinoma (MBC) is a heterogeneous group of invasive breast carcinoma with squamous, spindle cell, or mesenchymal elements. It may be monophasic or biphasic, and often coexists with invasive breast carcinoma of no special type (IBC-NST). Currently, there are no standardized guidelines for reporting MBC, and a diagnostic threshold for the metaplastic component is not established by the WHO classification.

Tell Me about yourself: Analyzing self-referential language use in borderline personality disorder.

Depression and some other illnesses are associated with increased self-reference and negative emotion in language. Research findings on lexical patterns in Borderline Personality Disorder (BPD) have been inconsistent. We conducted two studies to evaluate lexical markers of distress in BPD: First compared to healthy controls (HC), and later compared to Post-Traumatic stress disorder (PTSD) patients and trauma-exposed controls (TC).

Ketamine induces multiple individually distinct whole-brain functional connectivity signatures.

Background: Ketamine has emerged as one of the most promising therapies for treatment-resistant depression. However, inter-individual variability in response to ketamine is still not well understood and it is unclear how ketamine's molecular mechanisms connect to its neural and behavioral effects.

Methods: We conducted a single-blind placebo-controlled study, with participants blinded to their treatment condition.

Identification of Glandular (Acinar)/Tubule Formation in Invasive Carcinoma of the Breast: A Study to Determine Concordance Using the World Health Organization Definition.

Context.—: The Nottingham Grading System (NGS) developed by Elston and Ellis is used to grade invasive breast cancer (IBC). Glandular (acinar)/tubule formation is a component of NGS.
