Vaping involves the use of a device to deliver aerosolized nicotine and tetrahydrocannabinol (THC) oils to the lungs. Vaping continues to increase in popularity; however, because it is a novel drug delivery system there is little evidence regarding its safety and long-term consequences. Here, we present a 22-year-old Caucasian male who was admitted with acute hypoxic respiratory failure and massive hemoptysis. Contrasted computed tomography of the chest demonstrated ground glass opacities throughout all lung fields and bilateral pulmonary emboli. Bronchoalveolar lavage revealed increased red blood cell counts in serial aliquots, consistent with the diagnosis of diffuse alveolar hemorrhage (DAH). An extensive workup did not reveal an etiology for the DAH. However, further history was obtained, and the patient divulged daily vaping of THC. E-cigarette, or vaping, product use associated lung injury (EVALI) consists of a myriad of different lung injury patterns. Our case illustrates an uncommon presentation of EVALI with DAH and multiple pulmonary emboli.

Sepsis-induced acute lung injury (ALI) is a common acute and severe reason of death in the intensive care unit. Although the pathogenesis is complicated and multifactorial, elevated inflammation and oxidative stress are considered as fundamental mechanisms for the progression of ALI. Anemonin is a natural compound with diverse biological properties including anti-inflammatory and anti-oxidative effects.

Children with bronchopulmonary dysplasia (BPD) often exhibit severe respiratory problems and significant pulmonary dysfunction during school age and adulthood. Exercise tests show a decline in cardiopulmonary function and physical performance in children with BPD, who also have a higher incidence of pulmonary hypertension. These children generally perform poorly in terms of intelligence, language, and motor development.

Background: Sepsis is a systemic inflammatory syndrome that can cause coagulation abnormalities, leading to damage in multiple organs. Vascular endothelial cells (VECs) are crucial in the development of sepsis-induced coagulopathy (SIC). The role of Parthenolide (PTL) in regulating SIC by protecting VECs remains unclear.

The inflammatory response mediated by alveolar macrophages plays a crucial role in the development of acute lung injury. Numerous studies have reported that lncRNAs are highly expressed in acute lung injury in mouse models and cell lines, and acute lung injury (ALI) can be effectively alleviated by targeting these lncRNAs. The aim of this study was to explore the mechanism by LncRNA Gm26917 regulates the inflammatory response in alveolar macrophages during acute lung injury mouse model.

The incidence of blast injuries has been rising globally, particularly affecting the lungs due to their vulnerability. Primary blast lung injury (PBLI) is associated with high morbidity and mortality rates, while early diagnostic methods are limited. With advancements in medical technology, and portable handheld ultrasound devices, the efficacy of ultrasound in detecting occult lung injuries early remains unclear.
