Abstract

fetched live from OpenAlex

The aim of the present research was to analyze the epidemiological and clinical characteristics of the novel influenza A (H1N1) in China. We retrospectively analyzed the epidemiological information and clinical characteristics of 150 patients with the novel influenza A (H1N1) virus infection by descriptive epidemiology. There were 82 males and 68 females in this group. The median age of the 150 patients was 34.4 years (range, 4 to 77 years). There were 145 imported cases among the patients and most of these cases came from Australia, America and Canada. The main symptoms included fever, cough and sore throat. Other symptoms included: expectoration, runny nose, throat itching, sniffles, dry pharynx, headache, muscular ache, etc. CD4(+) T cell counts of 48% of the patients were lower than normal. Computed tomography (CT) of the chest in 32 cases was abnormal, including: increased bronchovascular shadows, pneumonia, pleural thickening and pleurisy, etc. Oseltamivir was the first choice for treatment of A (H1N1) influenza and it was safe and well tolerated. The symptoms were minor and the prognosis was good. All patients recovered fully after treatment. Considering the fact that the flu is highly infectious and can be carried through human to human contact rapidly, local Centers for Disease Control and prevention (CDC) should strengthen monitoring and take some measures in view of an influenza A (H1N1) onslaught.

Not 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.
