Lung fibrosis development utilizes alveolar macrophages, with mechanisms that are incompletely understood. Here, we fate map connective tissue during mouse lung fibrosis and observe disassembly and transfer of connective tissue macromolecules from pleuro-alveolar junctions (PAJs) into deep lung tissue, to activate fibroblasts and fibrosis. Disassembly and transfer of PAJ macromolecules into deep lung tissue occurs by alveolar macrophages, activating cysteine-type proteolysis on pleural mesothelium.

Article Synopsis
  • A subgroup of patients with oligometastatic cancer may benefit from local treatment of all cancer lesions to achieve longer disease-free survival, especially when brain metastases are involved.
  • An analysis of 7,000 PET scans identified 106 patients with both extracranial oligometastases and brain metastases, finding that brain involvement significantly impacted disease classification and treatment outcomes.
  • Patients with oligometastasic disease had a median survival of 28 months compared to 10 months for polymetastatic patients, suggesting that brain metastases should not automatically exclude individuals from clinical trials.

Previous research suggests that individuals with autism spectrum disorder (ASD) may experience working memory (WM) problems, but the nature of the underlying disruption remains unknown. A recent study (Bodner et al. 2019) found that young adults with ASD experienced intact WM capacity but disruptions in their ability to efficiently filter and allocate attention.

Purpose: Retrieval practice has been shown to assist the word learning of children with developmental language disorder (DLD). Although this has been true for learning new verbs as well as new nouns and adjectives, these children's overall verb learning has remained quite low. In this preregistered study, we presented novel verbs in transitive sentences with varying subjects/agents and objects/patients to determine if recall could be improved and if retrieval practice continued to be facilitative.

Article Synopsis
  • Surgical resection is the primary treatment for patients with large or symptomatic brain metastases, but there's still a risk of local failure, prompting the development of a prediction tool to identify those at high risk.
  • Data from the AURORA study included 253 patients for training and 99 for external testing, utilizing radiomic features from MRI scans to enhance prediction accuracy.
  • The elastic net regression model combining radiomic and clinical features showed a significant improvement in predicting local failure, with lower risk groups experiencing only 9% failure at 24 months compared to 74% in high-risk groups, suggesting potential for improved patient follow-up and treatment.

Purpose: The word learning of preschool-age children with developmental language disorder (DLD) is improved when spaced retrieval practice is incorporated into the learning sessions. In this preregistered study, we compared two types of spacing-an expanding retrieval practice schedule and an equally spaced schedule-to determine if one of these approaches yields better word learning outcomes for the children.

Method: Fourteen children with DLD aged 4-5 years and 14 same-age children with typical language development (TD) learned eight novel nouns over two sessions.

Background And Purpose: Limited data is available about the feasibility of stereotactic body radiation therapy (SBRT) for treating more than five extra-cranial metastases, and almost no data for treating more than ten. The aim of this study was to investigate the feasibility of SBRT in this polymetatstatic setting.

Materials And Methods: Consecutive metastatic melanoma patients with more than ten extra-cranial metastases and a maximum lesion diameter below 11 cm were selected from a single-center prospective registry for this in-silico planning study.

Article Synopsis
  • The study examines the optimal doses and fractionation in stereotactic body radiotherapy (SBRT) for patients with oligometastatic cancer, analyzing 1,099 registered patients from the OligoCare trial.
  • The analysis converted SBRT doses to biological effective doses (BED) using specific cancer types' α/β values, revealing that different cancers received varying doses based on type and metastasis locations.
  • Findings indicate that SBRT doses were adapted according to the primary cancers and metastasis sites, suggesting further research is needed on the safety and efficacy of this tailored approach.

Multiple adjustment difficulties have been associated with children's exposure to recent parental wartime military deployments, but long-term consequences have not yet been systematically studied. This investigation will assess direct and indirect relationships between exposures to parental deployments early in life and later youth adjustment. Parents' psychological health and family processes will be examined as mediators, and parents' and children's vulnerability and support will be examined as moderators.

Processive enzymes like polymerases or ribosomes are often studied in bulk experiments by monitoring time-dependent signals, such as fluorescence time traces. However, due to biomolecular process stochasticity, ensemble signals may lack the distinct features of single-molecule signals. Here, we demonstrate that, under certain conditions, bulk signals from processive reactions can be decomposed to unveil hidden information about individual reaction steps.

Background: Oligoprogression is defined as cancer progression of a limited number of metastases under active systemic therapy. The role of metastasis-directed therapy, using stereotactic body radiotherapy (SBRT), is controversial as is the continuation versus switch of systemic therapy. We report outcomes of oligoprogressive patients after SBRT, and compare those patients that continued or switched their current line of systemic therapy.

Objective: Although early diagnosis and treatment prevent the severe impairments associated with untreated phenylketonuria (PKU), individuals with early treated PKU (ETPKU) nonetheless experience significant neurocognitive and psychological sequelae, including difficulties in working memory (WM) and increased risk of anxiety. The primary objective of the present study was to examine the extent to which anxiety may moderate the relationship between ETPKU and WM performance.

Method: A sample of 40 adults with ETPKU and a demographically comparable sample of 40 healthy adults without PKU completed a comprehensive assessment of WM performance and anxiety symptomatology.
