Another cause of neonatal CAP is Chlamydia trachomatis, which, though acquired at birth, does not cause pneumonia until two to four weeks later. It ...
In a prediction rule study, investigators identify a consecutive group of patients who are suspected of having a specific disease or outcome. The investigators then obtain a standard set of clinical observations on each patient and a test or clinical follow-up to define the true state of the patient.
An entity can have multiple parents and child nodes. For example, pneumonia can be categorized as a lung infection , but also as a bacterial or viral infection (i.e. by site or by etiology ). Thus, the node Pneumonia (entity id: 142052508 ) has two parents: Lung infections (entity id: 915779102 ) and Certain infectious or parasitic diseases ...
Pneumonia may develop complications such as a lung abscess, a round cavity in the lung caused by the infection, or may spread to the pleural cavity. [ citation needed ] Poor oral care may be a contributing factor to lower respiratory disease, as bacteria from gum disease may travel through airways and into the lungs.
