The present study illustrates the effect of using the consolidated total score (obtained on a 7-point scale by adding the tubular, nuclear and mitotic scores) as well as double reporting on the interobserver reliability of breast cancer grading by the Nottingham method. 50 consecutive breast cancer slides were graded independently by 5 pathologists. The interobserver reliability between the individual pathologists for final grade, total score and grade components was estimated by quadratic weighted kappa (k(w)). Similarly, the inter-observer reliability of double reported scores (obtained by averaging the reported scores of two independent pathologists) for independent observer pairs was estimated. The total scores gave higher reliability figures than the final grade both for individual pathologists and double reported scores. The double reported total scores and grade also gave significantly higher reliability figures than the individual scores and grade (average k(w)=0.65 and 0.78 for the individual and double reported total scores, respectively; 0.61 and 0.66 for the individual and double reported grades).Therefore, use of total scores in addition to grade as well as double reporting of the same significantly increases the interobserver reliability of breast cancer grading.

Background: Magnetic seizure therapy (MST) has emerged as a promising alternative to electroconvulsive therapy (ECT) for treatment-resistant depression. Previous systematic reviews and meta analysis already showed its primary results, however, there are no recent reviews updating these findings.
Objectives: This systematic review aimed to make an updated systematic review of MST on unipolar and bipolar depression.

Background: Phenomenological psychopathologists have recently highlighted how people with delusions experience multiple realities (delusional and non-delusional) and have suggested this double bookkeeping cannot be explained via predictive processing. Here, we present data from Kamin blocking and extinction learning that show how predictive processing might, in principle, explain a pervasive sense of dual reality.
Methods: This cross-sectional study involved three participant groups: patients with schizophrenia (SZ; n=42), healthy participants with elevated esoteric beliefs (EEB; clairaudient psychics; n=31), and heathy controls (with neither illness nor significant delusional ideation, n=62).

Background & Aims: Considerable interest has been recently given to the potential role of the gut-brain axis (GBA) -a two-way communication network between the gut microbiota and the central nervous system- in the pathogenesis of attention-deficit hyperactivity disorder (ADHD), suggesting the potential usefulness of probiotic and synbiotic supplementations. In light of the limited available evidence, synbiotic efficacy in ADHD children not taking medications should be clarified. This study aimed to investigate the efficacy of a synbiotic dietary supplementation on fatty acids levels as well as on microbiota composition, behaviour, cognition, and brain function in children with ADHD.

Increasing evidence points to infectious diseases as contributor to the pathogenesis of neurodegeneration in Parkinson's disease (PD), probably driven by a peripheral and CNS inflammatory response together with alpha-synuclein (aSyn) pathology. Pro-inflammatory lipopolysaccharide (LPS) endotoxin is suggested as a risk factor, and LPS shedding gram-negative bacteria are more prevalent in the gut-microbiome of PD patients. Here, we investigated whether LPS could contribute to the neurodegenerative disease progression via neuroinflammation, especially under conditions of aSyn pathology.

Background: The combination of passive immune agents (human rabies immune globulin (HRIG) and equine rabies antiserum (ERA)) with vaccines are effective measures for preventing the onset of rabies post exposure. However, ERA and HRIG have potential risks of serum allergic reactions and blood-transmitted infectious diseases. This study compared the safety, pharmacokinetics and neutralizing activity of recombinant human anti-rabies monoclonal antibody NM57 injection (rhRIG, Ormutivimab) and HRIG in combination with rabies vaccine and vaccine alone.
