Objective: Obsessive-compulsive disorder (OCD) is associated with altered brain function related to processing of negative emotions. To investigate neural correlates of negative valence in OCD, we pooled fMRI data of 633 individuals with OCD and 453 healthy controls from 16 studies using different negatively-valenced tasks across the ENIGMA-OCD Working-Group.
Methods: Participant data were processed uniformly using HALFpipe, to extract voxelwise participant-level statistical images of one common first-level contrast: negative vs.
A national Australian Congenital Heart Disease registry; methods and initial results.

Background: Although several National Data Registries for Congenital Heart Disease (CHD) exist, few are comprehensive and contemporary. A National Australian CHD Registry has been developed that aims to redress this by creating the first comprehensive data collection for CHD children and adults, initially across Australia.
Methods: We defined and collected a minimum dataset of demographics, diagnoses, and procedures from people with CHD presenting at participating quaternary CHD services Australia-wide.
Background: Although the prognostic implications of severe mitral regurgitation (MR) are well recognised, they are less clear in moderate MR. We therefore explored the prognostic impact of both moderate and severe MR within the large National Echocardiography Database Australia cohort.
Methods: Echocardiography reports from 608 570 individuals were examined using natural language processing to identify MR severity and leaflet pathology.
Background: The tin (Sn) prefilter technique is a recently introduced dose-saving technique in computed tomography (CT). This study investigates whether there is an altered molecular biological response in blood cells using the tin prefiltering technique.
Methods: Blood from 6 donors was X-irradiated ex-vivo with 20 mGy full dose (FD) protocols (Sn 150 kV, 150 kV, and 120 kV) and a tin prefiltered 16.

Article Synopsis
- The American Association of Bronchology and Interventional Pulmonology aims to keep clinicians informed with brief, current reviews on essential interventional pulmonology topics, starting with malignant pleural disease.
- The article consists of three parts that update readers on malignant pleural effusion: diagnosis through imaging and fluid biomarkers, management strategies including multimodal approaches and targeted therapies, and details on pleural mesothelioma.
- These reviews are part of the Essential Knowledge series presented at the 2023 AABIP Annual Conference, and recorded lectures are available for access on the AABIP website.
