Article Synopsis
- A study investigated the relationship between hemoglobin levels and brain volume in a large group of elderly participants using MRI scans.
- It involved 2153 participants, mainly aged around 69, and found that lower hemoglobin levels were linked to reduced total white matter volume, especially in younger individuals.
- The study concluded that low hemoglobin levels can negatively impact white matter volume as people age, but didn't find significant effects on gray matter or hippocampal volumes.
Background And Purpose: Parkinson disease is a prevalent disease, with olfactory dysfunction recognized as an early nonmotor manifestation. It is sometimes difficult to differentiate Parkinson disease from atypical parkinsonism using conventional MR imaging and motor symptoms. It is also known that olfactory loss occurs to a lesser extent or is absent in atypical parkinsonism.

Purpose: This study aims to measure job satisfaction among interventional radiology physicians in Japan and analyze the factors affecting job satisfaction.
Material And Methods: A web-based survey was conducted among the members of the Japanese Society of Interventional Radiology between October and December 2021. Participants were questioned regarding their job satisfaction, workplace, work status, and demographic information.
Background: We investigated volumetric alterations in the bilateral choroid plexus (ChP) and brain ventricles of patients during their first episode of major depressive disorder (MDD) prior to antidepressant treatment.
Methods: Seventy-one first-episode drug-naïve patients with MDD and seventy-four healthy control (HC) subjects were recruited. MRI data were obtained, and bilateral ChP and brain ventricle volumes were evaluated using segmentation, based on the adaptive multiscale and expectation maximization method.
Article Synopsis
- Major depressive disorder (MDD) is a common mental health issue that affects motivation and pleasure, but its specific relationship with the reward system in first-episode, drug-naïve patients hasn't been explored thoroughly.
- The study involved 89 MDD patients and 82 healthy controls, investigating how the fronto-striato network (FSN) relates to age and depression scores while finding age's effect on FSN only in healthy individuals.
- Results showed that the FSN is influenced by both age and MDD, indicating a complex interaction, but there was no direct correlation between FSN and severity of depressive symptoms as measured by the Hamilton Rating Scale.
