Atypical face processing is commonly reported in autism. Its neural correlates have been explored extensively across single neuroimaging modalities within key regions of the face processing network, such as the fusiform gyrus (FFG). Nonetheless, it is poorly understood how variation in brain anatomy and function jointly impacts face processing and social functioning.

Memory deficits are a hallmark of many different neurological and psychiatric conditions. The Rey-Osterrieth complex figure (ROCF) is the state-of-the-art assessment tool for neuropsychologists across the globe to assess the degree of non-verbal visual memory deterioration. To obtain a score, a trained clinician inspects a patient's ROCF drawing and quantifies deviations from the original figure.

Autism spectrum disorder ("autism") is a neurodevelopmental condition characterized by substantial behavioral and neuroanatomical heterogeneity. This poses significant challenges to understanding its neurobiological mechanisms and developing effective interventions. Identifying phenotypically more homogeneous subgroups and shifting the focus from average group differences to individuals is a promising approach to addressing heterogeneity.

Background: Pulmonary endarterectomy (PEA) is the treatment of choice for chronic thromboembolic pulmonary hypertension (CTEPH). Although most have normalization of pulmonary artery (PA) pressures, development of residual pulmonary hypertension (RPH) is challenging to predict.

Research Question: Among patients with CTEPH undergoing PEA, is there a relationship between specimen histopathology and postoperative hemodynamics?

Study Design And Methods: In this single-center retrospective cohort study, patients with CTEPH who underwent PEA were classified by thrombus chronicity: organized (chronic), organizing (subacute), or mixed (combined organizing and organized).

Article Synopsis
  • Lung transplantation for patients with end-stage lung disease from COVID-19 is increasingly common, though there is a lack of comprehensive international studies on the subject.
  • In a multicenter analysis involving 11 major lung transplant centers, 46 out of 1606 lung transplants were performed due to COVID-19-related conditions, showing distinct demographic and clinical characteristics compared to other patients.
  • The 30-day survival rates for transplant recipients due to COVID-19 were found to be similar to those without COVID-19, suggesting that lung transplantation is a viable option for select patients suffering from COVID-19-related lung damage.

Heart failure with preserved ejection fraction (HFpEF) constitutes approximately 50% of heart failure (HF) cases, and encompasses different phenotypes. Among these, most patients with HFpEF exhibit structural heart changes, often with smaller left ventricular cavities, which pose challenges for utilizing ventricular assist devices (VADs). A left atrial to aortic (LA-Ao) VAD configuration could address these challenges, potentially enhancing patient quality of life by lowering elevated mean left atrial pressure (MLAP).

Recent advances in cognitive neurosciences suggest that intrinsic brain networks dynamics are associated with cognitive functioning. Despite this emerging perspective, limited research exists to validate this hypothesis. This Registered Report aimed to specifically test the relationship between intrinsic brain spatio-temporal dynamics and executive functions.

Exploring the neural basis of age-related decline in working memory is vital in our aging society. Previous electroencephalographic studies suggested that the contralateral delay activity (CDA) may be insensitive to age-related decline in lateralized visual working memory (VWM) performance. Instead, recent evidence indicated that task-induced alpha power lateralization decreases in older age.

  • The study investigates how traumatic stress, specifically Complex Posttraumatic Stress Disorder (CPTSD) and depression in asylum-seeking mothers, affects the mental health of their children after displacement.
  • It focuses on 127 Eritrean mothers in Israel with varying degrees of trauma and their preschool-aged children, analyzing how maternal mental health issues correlate with children's internalizing and externalizing difficulties.
  • Results indicate that mothers with CPTSD have a greater negative impact on their children's socio-emotional development compared to those with PTSD or depression alone, highlighting the need for targeted interventions for families affected by displacement.

Single-atom catalysts (SACs) comprise catalytically active atoms dispersed on supports; they combine the high activity and site uniformity of homogeneous catalysts with the ease of separability of heterogeneous catalysts. However, SACs lack fine control over the active site, provided by ligands in homogeneous catalysts. In this work, we demonstrate that modification of the support with an organic monolayer is a viable approach to improving the catalytic performance.

  • Magnetars are super-strongly magnetized neutron stars, and their formation is not fully understood.
  • Researchers studied the binary system HD 45166 and discovered it contains a Wolf-Rayet star with a mass of 2 solar masses and a magnetic field of 43 kilogauss.
  • They suggest that this Wolf-Rayet star, due to its heavy mass and strong magnetic field, will likely explode as a supernova and leave behind a magnetar remnant, possibly formed from the merger of two smaller helium stars.
