Summary: The prevalence of pulmonary fibrosis is increasing, and the burden is expected to rise due to COVID-19. Approved therapies only slow disease progression, highlighting the need for innovative treatments. Recent studies suggest that HBO may have a positive impact on pulmonary fibrosis, attenuating the severity in mouse models.

Summary: This study identifies FGF19 as an antifibrotic molecule with potential therapeutic interest in fibrotic lung disorders. In vivo and in vitro experiments demonstrate that FGF19 can decrease lung fibrosis and fibrotic markers, modulate apoptosis of lung epithelial cells, and prevent myofibroblast differentiation.

Summary: The deterioration of inhibitory synapses may be a neurological basis for abnormal social behaviors. Manipulating GABAergic transmission has been linked to improved sociability. Ephrin-B2 (EB2), a synaptic protein, plays a key role in the maintenance and rearrangement of inhibitory synapses in the medial prefrontal cortex (mPFC). However, the specific role of EB2 in inhibitory cell types in the pathophysiology and treatment of social deficits is still unknown. This study found that depletion of EB2 specifically occurred in GABAergic neurons, leading to social deficits. Overexpression of mPFC EB2 restored the defective social behavior. The findings suggest that the effect of EB2 on social deficits is specific to certain anatomical and cell types. Furthermore, an upregulation of HDAC4 expression was observed in EB2-deficient mice, with nuclear HDAC4 playing a role in mediating the mechanism underlying the impairment. Treatment with LMK235 significantly rescued social deficits, indicating a potential use for HDAC targeting agents in treating social deficits.

Summary: Lung fibrosis can occur in various settings, and the most common form is idiopathic pulmonary fibrosis, which is strongly associated with aging. Recent studies suggest that targeting certain components of aging biology may be effective in mitigating age-related fibrosis. This review explores molecular targets that may be relatively more selective in mediating tissue fibrosis, as well as epigenetic mechanisms and metabolic pathways that regulate aging and fibrosis.

Summary: Histone deacetylase 1 (HDAC1) inhibition plays an important role in reversing fibrosis. The study found that HDAC1 inhibition can reverse cell-to-cell transformation and limit cell migration and invasion by promoting the expression of miR-769-5p. Additionally, miR-769-5p targets and regulates the expression of several crucial genes.

Summary: The study showed that using the selective inhibitor Tubastatin A to inhibit HDAC6 has a significant effect on TBHP-treated chondrocytes and a mouse OA model, reducing oxidative stress and ECM degradation, maintaining chondrocyte survival, and activating autophagy. The results suggest that HDAC6 inhibition may prevent OA development and serve as a potential therapeutic target for OA management.

Summary: Bronchopulmonary dysplasia (BPD) is a common lung disease in premature infants caused by hyperoxia exposure and microbial dysbiosis. This study reveals that airway dysbiosis impairs Nrf2-dependent antioxidant function, leading to a more severe phenotype of BPD. Furthermore, supporting colonization with Lactobacillus species to enhance Nrf2-mediated antioxidant activity can improve dysbiotic-augmented lung injury.

Summary: Early identification of infants with bronchopulmonary dysplasia-associated pulmonary hypertension (BPD-PH) is crucial due to the higher risk of death. We investigated the intermittent hypoxemia (IH) patterns in infants with BPD-PH and compared them with infants with BPD alone. Our findings showed that infants with BPD-PH had longer duration of hypoxemic events, which was associated with both the diagnosis of BPD-PH and death in these infants.

Summary: Prediction of biomedical signal changes is useful for clinical applications, but evaluation and applicability of prediction tools depend on specific clinical contexts. This study proposes a novel method to evaluate and compare vital sign predictors and validates it for rare events scenarios. Experimental results show that simple statistical predictors can outperform state-of-the-art deep learning architectures for low-dimensional signals.

Summary: This study aims to analyze the relationship between social determinants of health (SDOH) and outcomes for extremely preterm infants. The results showed that infants born to mothers with public/no insurance had older postmenstrual age (PMA) at discharge and were more likely to be readmitted. Children exposed to multiple risk-associated SDOH at birth had higher rates of neurodevelopmental impairment (NDI) and death postdischarge compared to those not exposed.

Summary: This study aimed to investigate oxygenation patterns during two types of oxygen supplementation in preterm infants and assess their performance in hypoxemia risk screening during NICU monitoring. The findings showed that oxygen saturation had higher volatility and complexity during digitally-set servo-controlled oxygen environment supplementation. Additionally, variability measures of oxygen saturation exhibited early prognostic value in discriminating infants at higher risk of hypoxemic events. Multivariate models with two features showed good performance in risk stratification.

Summary: Mitochondrial dysfunction at birth is associated with the development of bronchopulmonary dysplasia (BPD) in extremely low-birth weight (ELBW) infants. Nebulized thyroid hormone (TH) has shown potential to improve mitochondrial function and reduce pulmonary fibrosis in adult animals. This study investigated the effects of intranasal T3 on neonatal lung injury and mitochondrial dysfunction in newborn mice, as well as its impact on lung fibroblasts and mesenchymal stem cells from ELBW infants. The results demonstrated that inhaled T3 attenuated hyperoxia-induced lung injury and improved mitochondrial function in mice, suggesting that TH supplementation might be a valuable therapeutic strategy for BPD.

Summary: The study found that cardioventilatory events peak during the first month of life in extremely preterm infants, but the trajectory afterwards depends on the type of event, race, sex, and use of mechanical ventilation. Apnea, periodic breathing, and intermittent hypoxemia events rose from day 3 of life then fell to near-resolution by 8-12 weeks of age. Apnea and intermittent hypoxemia were inversely correlated with gestational age, while periodic breathing was positively correlated with gestational age.

Summary: This study found that perceived stigma in healthcare settings during pregnancy is associated with psychological distress in the postpartum period. Individuals who reported stigma had higher levels of depression, anxiety, and anger, and lower levels of well-being. They were also more likely to experience food insecurity, adverse childhood experiences, and abuse during pregnancy, and had less emotional support.
