P1-S1.05 The detection rate of<i>Chlamydia trachomatis</i>and<i>Mycoplasma genitalium</i>infections in STD clinics in Novosibirsk, Russian Federation
Bibliographic record
Abstract
Background Currently, in Russia, the incidence of syphilis, gonorrhoea, chlamydia, trichomoniasis, urogenital herpes, and anogenital warts are officially registered. However, statistical records and reporting forms do not include mycoplasma infections (eg,Mycoplasma genitalium). Methods The aim of the present study was to evaluate the detection rates ofChlamydia trachomatisandM genitaliuminfections in patients who had attended to STD clinics in Novosibirsk in 2009–2010. A total of 9208 and 13 006 patients were examined forM genitaliumandC trachomatis, respectively, in different settings (antenatal clinics, hospitals, health centers, STI clinics). Both infections were tested in urethral and/or cervical swabs with nucleic acid amplification techniques (“Litex” and “DNA technology”, Russia). Results The detection rates ofM genitaliumandC trachomatishad not changed over 2009 and 2010, accounting to 12.6–12.6%, and 12.9–13.0%, respectively. Coinfection was observed in only 0.55% of examinies. However, seasonal variations showed different patterns for these two infections (Abstract P1-S1.05 figure 1). Statistical analysis by month revealed that the highest rates ofM genitaliumwere reported in February and March, and the lowest ones—in July. Monthly analysis found even distribution of infection withC trachomatisalong a year, while the lowest incidence was found in July. Abstract P1-S1.05 Figure 1 Detection rates ofMycoplasma genitaliumandChlamydia trachomatisaccording to the attendance data (by month in %). Conclusions The incidence rates ofC trachomatisandM genitaliumare approximately the same and account for 12–13% among men and women, equally. The combination of these infections is rare (0.55%). During 2009–2010, there are parallel trends in the detection of these two infections, but in September the reciprocal event was shown. This discrepancy may be due to the peculiarities of various microorganisms, and the clinical signs of the infection—chlamydia can cause non-gonococcal urethritis, which is the reason for examination, and mycoplasma infection is mainly symptomless. Nevertheless, a hypothesis of various patterns of infections prevalence around a year in northern countries (ie, Canada, Alaska, Scandinavia, Russia) needs further clarification. The post-holiday period (September–October) may be a crucial point in the activity of the infectious process.

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.
