Diffuse alveolar hemorrhage is a rare but fatal manifestation of SLE, typically reported in well-established diagnoses of SLE. DAH itself as a presenting symptom is quite rare. In this case, we present a 24-year-old pregnant female at 10 weeks of gestation without a history of SLE presenting with DAH.

Virus infection is a common cause of lung injury and can result in lung fibrosis in severe cases. Furthermore, it is a significant trigger of disease exacerbation in patients with lung fibrosis. However, nearly all the case reports or case series to date have focused on the adult population rather than the pediatric population.

Background: H1N1 influenza virus can cause diffuse alveolar damage, such as pneumonia and pulmonary fibrosis, when it infects the respiratory tract. Metformin not only improves chronic inflammation but also has direct anti-inflammatory effects. Therefore, the focus of this study was on the molecular mechanism and regulatory mechanism of metformin against influenza virus in alleviating lung disease.

Post-acute sequelae of SARS-CoV-2 (PASC or "long COVID") and chronic fatigue syndrome/myalgic encephalitis (CFS/ME) share symptoms such as exertional dyspnea. We used exercise oxygen pathway analysis, comprising six parameters of oxygen transport and utilization, to identify limiting mechanisms in both conditions. Invasive cardiopulmonary exercise testing was performed on 15 PASC patients, 11 CFS/ME patients, and 11 controls.

Therefore, the female patients are often overlooked and under-investigated. This study aimed to evaluate the clinical characteristics and all-cause mortality in female patients with IPF in Chinese population.
