A newborn infant is born at 31 weeks’ gestation to a G1P1 mother with a history of Type 2 Diabetes. During the initial newborn evaluation, he is found to have nasal flaring, expiratory grunting, and intercostal retractions. A chest radiograph is obtained (see image below) and is noted to have a ground-glass appearance. He is emergently intubated but continues to have decreased oxygen saturation, so he is transferred to the neonatal intensive care unit. Which of the following is the most likely underlying cause of this patient’s symptoms?

A 62-year-old male presents to the Emergency Department complaining of cough and chest pain. He states that the chest pain has been present for 2 weeks and worsens when he coughs. The patient has not been to a doctor in “years.” Initial CXR is obtained that is consistent with left-sided pneumonia. The patient is admitted for antibiotic treatment of pneumonia. On day 4 of his hospital course, the patient’s respiratory status worsens. Vital signs: 100°F, HR 118/min, RR 30/min, and oxygen saturation is 76% (room air). On physical exam, the patient appears drowsy and dyspneic. He cannot speak in full sentences. Lung exam reveals bilateral rales, and intercostal retractions are noted. The patient is placed on mechanical ventilation with improvement of his oxygen saturation to 84%. A repeat CXR is obtained (see image below) and reveals diffuse, bilateral coalescent opacities.                                                                                                                        Which of the following statements about this condition is TRUE?
