Human Metapneumovirus as a Cause of Severe Respiratory Illness in the Second Trimester of Pregnancy: Two Cases
Bibliographic record
Abstract
Despite being a fairly common cause of respiratory infection in adults, there have been few reported cases of human metapneumovirus (hMPV) in pregnancy. Other viruses, such as influenza, have been heavily reported on, and it is well established that these illnesses are detrimental to the pregnant population. However, we currently have limited data about hMPV’s effect. First, we discuss the case of a patient who presented to the emergency department in the second trimester with severe shortness of breath and was ultimately diagnosed with hMPV. Second, we discuss the case of a patient who presented as an intensive care unit transfer in the second trimester in severe respiratory distress with a positive test for hMPV at the outside facility. These cases highlight the fact that inpatient management might be needed to treat hMPV in pregnant patients, even for those without a significant prior respiratory medical history. Given the limited number of published cases of hMPV in the antepartum patient population, we hope to provide guidance for management of such cases and highlight the importance of prompt diagnosis in pregnant populations.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
