Summary: This study examined the presence of hypertensive microvascular disease in individuals with obstructive sleep apnoea (OSA) compared to those with chronic obstructive pulmonary disease (COPD) and hospital controls. The results showed that individuals with OSA had higher mean arterial pressure, more microvascular retinopathy, and narrower retinal arterioles compared to other patients. These findings suggest that OSA is associated with a higher risk of microvascular disease.

Summary: Tumor heterogeneity leads to drug resistance in cancer treatment, with sphingolipids playing a crucial role in cell fate and stress signaling. This study analyzed sphingolipid metabolism and autophagic flux in the A549 lung cancer model to study the interactions of chemotherapy drugs. The results showed that combining chemotherapies with autophagy inducers effectively reduced cell viability, but paclitaxel often had antagonistic effects. Further research is needed to identify specific sphingolipids accumulating in autophagosomes.

Summary: This study investigated the mechanism of Reduning in the treatment of SALI and found that it likely attenuated SALI by targeting AKT1. In vivo and in vitro experiments showed that Reduning reduced apoptosis and mitochondrial damage, lowered TNF-α levels, and improved survival rate in septic mice. Additionally, Reduning enhanced the binding capability of mTOR and Bax.

Summary: This study found that serum cadmium levels were higher in COPD patients compared to controls, and increased with disease severity. Autophagy and apoptosis markers were elevated in the lungs of COPD patients, and were positively associated with serum cadmium levels. Pulmonary function decline in COPD patients was partially attributed to cadmium-induced autophagy and apoptosis.

Summary: This study aimed to investigate the protective effect of p38 inhibition against SAP-ALI. In vitro experiments demonstrated that p38 activation increased apoptotic rates and cytokine levels in PMVECs. In vivo experiments showed that SB203580 could alleviate lung histopathological injury, reduce inflammatory activity, and preserve pulmonary function.

Summary: This study investigated the role of bone marrow mesenchymal stem cells (BMSCs) on vascular injury in a COPD-OSA overlap syndrome (OS) rat model. The findings suggest that BMSCs can repair vascular injury by inhibiting endothelial cell damage and apoptosis, providing a theoretical basis for the treatment of cardiovascular diseases caused by OS with BMSCs.

Summary: Chronic obstructive pulmonary disease (COPD) is a common, preventable, and treatable disease characterized by irreversible airflow obstruction and lung function decline. SIRT1, a member of the Sir2 family, plays important roles in oxidative stress, apoptosis, inflammation, autophagy, and cellular senescence, which are involved in the pathogenesis and development of COPD. SIRT1 activation may be a potential therapeutic strategy for COPD.

Summary: Autophagy is a cellular process that removes damaged molecules and organelles, and abnormalities in autophagy may contribute to the pathogenesis of chronic diseases like asthma and COPD. Autophagy can be either increased or decreased depending on the cell type and environment, making it challenging to target therapeutically. Some existing drugs can activate or inhibit autophagy, but more selective drugs are being developed.

Summary: Chronic obstructive pulmonary disease (COPD) is a global health problem that leads to high morbidity, mortality, and healthcare utilization. Its main causes are exposure to harmful particles, such as tobacco smoke and pollutants. Recent research has shown that various factors throughout the life course increase the risk of developing COPD. Innovations in omics and imaging techniques have provided greater understanding of the disease's pathophysiology, potentially leading to advancements in its prevention, diagnosis, and treatment. This review focuses on recent advances in the epidemiology, pathophysiology, imaging, diagnosis, and treatment of COPD.

Summary: This study identifies a novel mechanism by which GFI1 regulates the growth and survival of high risk multiple myeloma (MM) cells through modulation of sphingolipid metabolism. Regardless of p53 status, GFI1 increases intracellular levels of sphingosine-1-phosphate, stabilizing c-Myc and promoting MM cell viability. This finding suggests GFI1 as a potential therapeutic target for the treatment of MM, specifically in patients with non-functional p53.

Summary: This study demonstrates that enhancing S1P1 signaling can improve CS-induced emphysema, reducing lung cell apoptosis and airspace enlargement. Additionally, S1P1 agonists have modest inhibitory effects on CS-induced airspace inflammation and lung functional changes. The S1P1 signaling pathway plays an important role in maintaining the structural integrity of alveoli, and increasing both S1P1 signaling and abundance may be beneficial in counteracting the effects of chronic cigarette smoking.

Summary: Inhibition of IL-4/IL-13 signaling by dupilumab allows restoration of skin lipid composition and barrier function in patients with moderate-to-severe AD. Treatment with dupilumab significantly decreased TEWL in AD lesions, normalized lipid composition, and increased ceramide chain length in lesional and non-lesional stratum corneum of AD patients, achieving a full response after 8 weeks of treatment.

Summary: This study examined the role of leukocyte HIF-1α in the development of cigarette smoke-induced lung disease using mice with conditional deletion or overexpression of HIF-1α. The results showed that overexpression of leukocyte HIF-1α did not affect the development of cigarette smoke-induced lung disease, suggesting that this signaling pathway is not involved in the development of murine lung disease.

Summary: Exercise intolerance is a common symptom in patients with post-acute sequelae of severe acute respiratory syndrome coronavirus infection (PASC), also known as long-COVID. This study aimed to determine if the metabolic disturbances observed in acute COVID-19 patients are also present in PASC. The results showed that PASC patients have altered fatty acid metabolism and dysfunctional mitochondrial lipid catabolism, which may contribute to exercise intolerance. These findings provide insights into the metabolic changes associated with PASC and suggest potential therapeutic strategies targeting mitochondrial function.

Summary: The concentration of C16:0-ceramide in the plasma of COVID-19 patients was significantly increased compared to healthy individuals. Autopsied lungs of individuals with COVID-ARDS showed a massive elevation of C16:0-ceramide and exhibited a previously unrecognized microvascular ceramide-staining pattern and increased apoptosis. C16:0-ceramide may be implicated in the vascular injury associated with COVID-19.

Summary: This study aimed to investigate the epidermal lipid profiles and their association with skin microbiome compositions in children with atopic dermatitis (AD). Skin tape stripping was used to obtain specimens from AD children and healthy subjects. The results showed that AD lesional skin had increased levels of certain ceramides, sphingomyelin, and lysophosphatidylcholine compared to nonlesional skin and control subjects. The lipid ratio and the proportions of certain bacteria were found to be associated with skin barrier dysfunction. These findings suggest that aberrant lipid profiles in pediatric AD skin are linked to microbial dysbiosis and cutaneous barrier dysfunction.
