    Objectives: Identifying early markers of poor prognosis of coronavirus disease 2019 (COVID-19) is mandatory. Our purpose is to analyze by chest radiography if rapid worsening of COVID-19 pneumonia in the initial days has predictive value for ventilatory support (VS) need. Methods: Ambispective observational ethically approved study in COVID-19 pneumonia inpatients, validated in a second outpatient sample. Brixia score (BS) was applied to the first and second chest radiography required for suspected COVID-19 pneumonia to determine the predictive capacity of BS worsening for VS need. Intraclass correlation coefficient (ICC) was previously analyzed among three radiologists. Sensitivity, specificity, likelihood ratios, AUC, and odds ratio were calculated using ROC curves and binary logistic regression analysis. A value of p < .05 was considered statistically significant. Results: A total of 120 inpatients (55 ± 14 years, 68 men) and 112 outpatients (56 ± 13 years, 61 men) were recruited. The average ICC of the BS was between 0.812 (95% confidence interval 0.745–0.878) and 0.906 (95% confidence interval 0.844–0.940). According to the multivariate analysis, a BS worsening per day > 1.3 points within 10 days of the onset of symptoms doubles the risk for requiring VS in inpatients and 5 times in outpatients (p < .001). The findings from the second chest radiography were always better predictors of VS requirement than those from the first one. Conclusion: The early radiological worsening of SARS-CoV-2 pneumonia after symptoms onset is a determining factor of the final prognosis. In elderly patients with some comorbidity and pneumonia, a 48–72-h follow-up radiograph is recommended.

    Eficacia de la capacidad y la eficiencia pronósticas de la herramienta de inteligencia artificial Thoracic Care Suite de GE aplicada a la radiografía torácica de pacientes con neumonía COVID-19

    Objective: Rapid progression of COVID-19 pneumonia may put patients at risk of requiring ventilatory support, such as non-invasive mechanical ventilation or endotracheal intubation. Implementing tools that detect COVID-19 pneumonia can improve the patient's healthcare. We aim to evaluate the efficacy and efficiency of the artificial intelligence (AI) tool GE Healthcare's Thoracic Care Suite (featuring Lunit Insight CXR, TCS) to predict the ventilatory support need based on pneumonic progression of COVID-19 on consecutive chest X-rays. Methods: Outpatients with confirmed SARS-CoV-2 infection, with chest X-ray (CXR) findings probable or indeterminate for COVID-19 pneumonia, who required a second CXR due to unfavorable clinical course, were collected. The number of affected lung fields for the 2 CXRs was assessed using the AI tool. Results: One hundred fourteen patients (57.4 ± 14.2 years; 65 of them were men, 57%) were retrospectively collected; and 15 (13.2%) required ventilatory support. Progression of pneumonic extension ≥ 0.5 lung fields per day compared to pneumonia onset, detected using the TCS tool, increased the risk of requiring ventilatory support by 4-fold. Analyzing the AI output required 26 seconds of radiological time. Conclusions: Applying the AI tool, Thoracic Care Suite, to CXR of patients with COVID-19 pneumonia allows us to anticipate ventilatory support requirements requiring less than half a minute.

    Morphological and osteological malformations in hatchery bred redline torpedo fish, Sahyadria denisonii (Day 1865) (Cyprinidae)
    (Universidad de Murcia, 2016) Sajeevan, Sajan; Anna-Mercy, Thoranam Varkey
    Malformaciones morfológicas y oseas en ejemplares de criadero de barbo de línea roja, Sahyadria denisonii (Day 1865) (Cyprinidae) Se publican, por primera vez, malformaciones morfológicas y osteológicos de Sahyadria denisonii producidas en criadero. Se fotografiaron anomalías morfológicas con cámara digital y de rayos X digital. De 950 larvas producidas, sólo 12 individuos (1,26 %) presentaron algún tipo de anomalía, incluyendo lordosis, escoliosis, cifosis, semi-opérculo, deformidad de la aleta, deformidad de la boca, deformación de la cabeza y deformidades múltiples. La causa exacta de anomalías no se pudo determinar, pero se discuten las posibles etiologías. Sin embargo, el registro actual es significativo debido a la aparición de deformidades en peces ornamentales de agua dulce de criadero, para los que se considera la reproducción inducida como la clave de su conservación.

    Urethrography in Men: Conventional Technique versus Clamp Method
    (Radiological Society of North America, 2009-07-01) Berná Mestre, Juan de Dios; Aparicio Mesón, Martín; Canteras Jordana, Manuel; Berná Serna, Juan De Dios; Dermatología, Estomatología, Radiología y Medicina Física
    To compare examination adequacy and patient discomfort during retrograde urethrography (RUG) performed by using the conventional balloon method versus those of RUG and voiding cystourethrography (VCUG) performed with he clamp method of using drip infusion for the administration of contrast material. Materials and Methods: This prospective study was approved by the institutional review board; written informed consent was obtained from all patients. Eighty men (mean age, 64.3 years; range, 18 – 85 years) suspected of having urethral stenosis were randomly distributed into two groups for urethrography: a control group (n 36) and a clamp group (n 44). In 11 of the 36 patients in the control group, the conventional balloon method could not be used, so these patients were transferred to the clamp group. Drip infusion was used to administer contrast material for RUG, and, except in cases where a suprapubic catheter was used (n 8), for VCUG. The pain levels reported by patients were recorded by using a verbal descriptor scale (VDS) and a visual analogue scale (VAS). Results: In the control group, RUG was successfully performed in 69% of patients (25 of 36), and mean pain levels recorded on inflation of the balloon were distressing according to the VDS and 4.8 (range, 2.3–7.5) according to the VAS. In the clamp group, RUG was successfully performed in all cases; in 69% of patients in this group (38 of 55), the pain level recorded at external compression was no pain according to the VDS and 0 according to the VAS, while mean values in the remaining 31% of patients (17 of 55) were mild pain on the VDS and 0.6 (range, 0.3–1.2) on the VAS. Bladder filling for VCUG was achieved with drip infusion in 96% of patients (69 of 72) in an average time of 11 minutes. Conclusion: The conventional balloon method of performing RUG is painful and, in some cases, not effective. The clamp method is a simple, well-tolerated procedure that allowed diagnostic evaluation in all cases. Drip infusion enables RUG and VCUG to be performed without the need for syringes or bladder catheters, thus increasing patient comfort.
