Abstract
espanolObjetivos: valorar la efectividad y seguridad de la inyeccion de dosis unica de acido hialuronico estabilizado de origen no animal (NASHA) para el tratamiento del dolor secundario a gonartrosis. Material y metodos: se han incluido un total de 37 pacientes afectos de gonartrosis diagnosticada previamente por el Traumatologo/Reumatologo en los que ha fracasado el tratamiento conservador y/o que no son tributarios de tratamiento quirurgico. Se les ha efectuado una infiltracion en dosis unica de acido hialuronico estabilizado no animal (NASHA), Durolane®. Se han recogido datos demograficos, efectos adversos e intensidad del dolor (valorada mediante escala verbal numerica) y puntuacion en los cuestionarios Western Ontario and McMaster Universities Osteoartritis Index (WOMAC) y Barthel -basal, a las 2 semanas, a los 3 meses y a los 6 meses de la infiltracion-. Se ha considerado efectiva una disminucion ≥ 30% durante mas de 3 meses en las puntuaciones basales. Resultados: los pacientes son mayoritariamente mujeres (83,8%), con una edad media de 72,8 anos (desviacion tipica -S- = 8,4) e indice de masa corporal medio (IMC) 31,9 (S = 6,9). La rodilla infiltrada es izquierda en el 51,7%, derecha en el 41,4% y bilateral en el 6,9% de los pacientes. Han presentado efectos adversos en forma de artralgias bien toleradas el 11,1% de los pacientes. En base a los resultados, la infiltracion con dosis unica de acido hialuronico estabilizado de origen no animal (NASHA) por gonalgia de origen artrosico provoca una reduccion estadisticamente significativa en la intensidad del dolor (escala verbal numerica y WOMAC) y de la capacidad funcional (WOMAC) en todos los intervalos valorados. Se ha producido una reduccion ≥ 30% en la intensidad del dolor en el 54% (valor que coincide con la reduccion en la puntuacion WOMAC de dolor), en la rigidez en el 62,1% y en la capacidad funcional en el 48,6% de los pacientes. Conclusiones: en nuestros pacientes, la viscosuplementacion intrarticular con dosis unica de acido hialuronico estabilizado de origen no animal (NASHA, Durolane®) para el tratamiento del dolor secundario a gonartrosis ha resultado efectiva y segura y supone un arma mas para el manejo del dolor y la invalidez que genera la gonartrosis. EnglishObjective: to evaluate the effectiveness and safety of single-dose injection of stabilized hyaluronic acid of non-animal origin (NASHA) for the treatment of pain related to knee osteoarthritis. Material and methods: we included a total of 37 patients with previously diagnosed gonarthritis by the Orthopedist/Rheumatologist in which conservative treatment has failed and/or who are not candidates for surgery. They carried out a single-dose injection of non-animal stabilized hyaluronic acid (Durolane®). We collected demographic data, adverse effects and pain intensity (assessed by verbal numeric scale) and scores on the questionnaires Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Barthel -baseline, at 2 weeks, at 3 months and 6 months of infiltration-. It has been considered effective a decrease ≥ 30% for more than 3 months at baseline scores. Results: patients are predominantly female (83.8%) with a mean age of 72.8 years (standard deviation = -S-8.4) and mean body mass index (BMI) 31.9 (S = 6.9). The left knee is infiltrated in 51.7%, 41.4% right and bilateral in 6.9% of patients. Adverse effects have occurred as well tolerated arthralgia 11.1% of patients. Based on the results, the infiltration with single dose of stabilized hyaluronic acid of non-animal origin for osteoarthritic source gonalgia caused a statistically significant reduction in pain intensity (numerical verbal scale and WOMAC) and functional capacity (WOMAC) at all measured intervals. There has been a ≥ 30% reduction in pain intensity in 54% (value that matches the reduction in WOMAC pain score) in 62.1% stiffness and functional capacity in 48.6% of patients. Conclusion: in our patients, intra-articular viscosupplementation single dose of stabilized hyaluronic acid of non-animal origin (NASHA, Durolane®) for the treatment of pain related to gonarthritis has been effective and safe and is a weapon for the management of pain and disability gonarthritis generated.

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.
