A secretome screen in primary human lung fibroblasts identifies FGF9 as a novel regulator of cellular senescence.

Senescent cells contribute to the pathogenesis of idiopathic pulmonary fibrosis (IPF), a disease with significant unmet need and therefore, there is an interest in discovering new drug targets that regulate this process. We design and perform a phenotypic screen with a secreted protein library in primary human lung fibroblasts to identify modulators of cell senescence. We identify FGF9 as a suppressor of several senescence phenotypes reducing stimulated p21 expression, enlarged morphology, DNA damage and SASP secretion, which is consistent with both DNA-damage and ROS induced senescence.

Sex disparity in adult asthma-A potential immunomodulatory role of let-7 family microRNAs.

Background: Sex differences have been reported in the incidence, prevalence and severity of asthma. Previous findings from animal models have revealed sex-related differences in inflammatory pathways that may contribute to asthma pathogenesis, but human studies are limited.

Methods: Airway and blood samples (n = 55 and n = 85 respectively) were collected from adult females and males with asthma and healthy subjects.

Predicting Early Death in Head and Neck Cancer-A Pilot Study.

The aim of this study was to evaluate biomarkers and biological characteristics of tumor biopsies from patients with head and neck cancer (HNC) to assess the risk of early death. Furthermore, we analyzed whether any combination of markers could be used for the prognostication of death within six months after cancer diagnosis. Patients diagnosed with HNC, receiving curative treatment decision at a multidisciplinary tumor board meeting, and who died within six months of diagnosis were included in this study.

Physical Color Calibration of Digital Pathology Scanners for Robust Artificial Intelligence-Assisted Cancer Diagnosis.

The potential of artificial intelligence (AI) in digital pathology is limited by technical inconsistencies in the production of whole slide images (WSIs). This causes degraded AI performance and poses a challenge for widespread clinical application, as fine-tuning algorithms for each site is impractical. Changes in the imaging workflow can also compromise diagnostic accuracy and patient safety.

Increased risk of autism in extremely preterm children with a history of retinopathy of prematurity.

Aim: To investigate the association between retinopathy of prematurity and autism spectrum disorder in extremely preterm children.

Methods: Data in children born extremely preterm at <28 weeks' gestational age in the Region Västra Götaland, 2013-2017, were analysed for association between retinopathy of prematurity and neurodevelopmental disorders. We focussed on autism spectrum disorder and excluded children with perinatal brain injuries or genetic disorders.
