Female sex and age-based advantage of simulated electric field in TMS to the prefrontal cortex in schizophrenia and mood disorders.

This study investigates computational models of electric field strength for transcranial magnetic stimulation (TMS) of the left dorsolateral prefrontal cortex (DLPFC) based on individual MRI data of patients with schizophrenia (SZ), major depressive disorder (MDD), bipolar disorder (BP), and healthy controls (HC). In addition, it explores the association of electric field intensities with age, gender and intracranial volume. The subjects were 23 SZ (12 male, mean age = 45.

Aberrant brain dynamics of large-scale functional networks across schizophrenia and mood disorder.

Introduction: The dynamics of large-scale networks, which are known as distributed sets of functionally synchronized brain regions and include the visual network (VIN), somatomotor network (SMN), dorsal attention network (DAN), salience network (SAN), limbic network (LIN), frontoparietal network (FPN), and default mode network (DMN), play important roles in emotional and cognitive processes in humans. Although disruptions in these large-scale networks are considered critical for the pathophysiological mechanisms of psychiatric disorders, their role in psychiatric disorders remains unknown. We aimed to elucidate the aberrant dynamics across large-scale networks in patients with schizophrenia (SZ) and mood disorders.

Structural connectivity between the hippocampus and cortical/subcortical area relates to cognitive impairment in schizophrenia but not in mood disorders.

Cognitive impairment in schizophrenia and other psychiatric disorders is a challenge to be overcome in order to maintain patients' quality of life and social function. The neurological pathogenesis of cognitive impairment requires further elucidation. In general, the hippocampus interacts between the cortical and subcortical areas for information processing and consolidation and has an important role in memory.

Computational modeling of electric fields for prefrontal tDCS across patients with schizophrenia and mood disorders.

This cross-diagnostic study aims to computationally model electric field (efield) for prefrontal transcranial direct current stimulation in mood disorders and schizophrenia. Enrolled were patients with major depressive disorder (n = 23), bipolar disorder (n = 24), schizophrenia (n = 23), and healthy controls (n = 23). The efield was simulated using SimNIBS software (ver.

Two cases of steroid dementia showing partial recovery during 2-year follow-up.

Background: Steroid dementia has been reported since the 1970s. In the current super-aged society, it increasingly receives attention because of the growing number of elderly people that are medicated with steroids for systemic rheumatic disease.

Case Presentation: We report two cases of steroid dementia that were diagnosed as a result of careful observation of clinical symptoms and biological examination, including nuclear medicine tests.

Hippocampal Subfield Volumes and Cognitive Function in Schizophrenia and Mood Disorders.

Introduction: The hippocampus is relevant to cognitive function in schizophrenia (SCZ) and mood disorder patients. Although not anatomically uniform, it is clearly divided into subfields. This study aimed to elucidate the relationship between hippocampal subfield volume and cognitive function in patients with SCZ, bipolar disorder (BP), and major depressive disorder (MDD).

Nivolumab-induced membranous nephropathy in a patient with stage IV lung adenocarcinoma.

Immune check point inhibitors (ICIs) are now increasingly used for cancer therapy. At the same time, by activating the immune system, ICIs induce unique side effects, termed immune-related adverse events (irAEs). Renal irAEs, although uncommon, result in acute tubulointerstitial nephritis.

A case of proliferative glomerulonephritis with immunoglobulin A1-lambda deposits successfully treated by chemotherapy.

A 74-year-old man presented with nephrotic syndrome and kidney insufficiency. Laboratory tests revealed monoclonal gammopathy of immunoglobulin A-lambda. Renal biopsy revealed diffuse mesangial proliferation and double-contoured basement membranes.
