The sex differences in use, safety outcomes, and health-care resource use of patients with pulmonary embolism (PE) undergoing percutaneous pulmonary artery thrombectomy are not well characterized. ⋯ In this large nationwide cohort, women with PE who underwent percutaneous thrombectomy showed higher morbidity and in-hospital mortality compared with men.

Lung ultrasound (LUS) scanning is useful to diagnose and assess the severity of pulmonary lesions during COVID-19-related ARDS (CoARDS). A conventional LUS score is proposed to measure the loss of aeration during CoARDS. However, this score was validated during the pre-COVID-19 era in patients with ARDS in the ICU and does not consider the differences with CoARDS. An alternative LUS method is based on grading the percentage of extension of the typical signs of COVID-19 pneumonia on the lung surface (LUSext). ⋯ LUSext is a valid measure of the severity of the lesions when compared with the CT scan. Not only are LUSext and CTvol correlated, but they also have similar inverse correlation with the severity of respiratory failure. LUSext is a practical and simple bedside measure of the severity of pneumonia in CoARDS, whose clinical and prognostic impact need to be investigated further.

Overdiagnosis of lung cancer by low-dose CT (LDCT) screening has raised concerns globally. LDCT screening has been used widely in employee health examinations in China since 2011. ⋯ The results provide evidence at a population level for lung cancer overdiagnosis in Chinese women resulting from increasing LDCT screening in the low-risk populations. Criteria for LDCT screening and management of screening-detected nodules need to be addressed fully for expanded application of LDCT screening in China.

Case Reports
A 45-Year-Old Woman With Unexplained Iron Deficiency Anemia and No Respiratory Symptoms.
A 45-year-old Japanese woman was diagnosed with anemia in a work place medical check-up and came to our hospital for further investigations. She had experienced general fatigue and orthostatic dizziness for 6 months without fever or respiratory symptoms, including cough, sputum, hemoptysis, or dyspnea. ⋯ She had no significant positive medical history and was not on any regular medication or supplements. She had no history of alcohol abuse or smoking.

A 17-month-old male infant with history of an abnormal chest shadow in the left lung lower lobe was admitted to our hospital for the resection of the malformation. At 9 months of age, he was admitted to his local hospital because of a persistent cough. ⋯ However, no thoracic abnormalities were seen in antenatal ultrasonography, and no clinical symptoms were observed at birth. After anti-inflammatory treatments given to this infant, he achieved remission and was discharged from his local hospital.
