Gasto urinario alto como predictor de hipoparatiroidismo tras tiroidectomía total.

OBJETIVO: Determinar la utilidad del gasto urinario alto como predictor temprano de bajo costo para hipoparatiroidismo posoperatorio. MÉTODO: Se realizó un estudio retrospectivo unicéntrico a 1 año en adultos sometidos a tiroidectomía total en The American British Cowdray Medical Center I.A.P., calculando el gasto urinario en 24 horas, utilizando valores de calcio sérico corregido por albúmina con una tabla de correlación e identificando a los pacientes que recibieron calcio suplementario en las primeras horas de posoperatorio. Se dividieron en pacientes con hipoparatiroidismo posoperatorio y con valores normales de calcio en el primer día, diferenciando a los que recibieron suplementación oral de calcio profiláctico. RESULTADOS: Se estudiaron 47 pacientes, 19 (40%) en el grupo con hipocalcemia posoperatoria y 28 (59.5%) en el grupo sin hipocalcemia posoperatoria. La media de gasto urinario en las primeras 8 horas de posoperatorio fue mayor en el grupo de hipocalcemia posoperatoria en comparación con el grupo sin hipocalcemia, sin diferencia significativa (p = 0.392), y tampoco durante las primeras 16 horas (p = 0.435). CONCLUSIONES: En nuestro estudio no existe relación entre el incremento del gasto urinario y la predicción de hipoparatiroidismo posoperatorio. Se necesitan estudios con muestras de mayor tamaño y con un diseño metodológico más fuerte (prospectivo) para determinar si en realidad la diferencia obtenida puede figurar como predictor. OBJECTIVE: to determine the usefulness of high urine output as a low-cost early predictor for postoperative hypoparathyroidism.. METHOD: A study was conducted inside The American British Cowdray Medical Center I.A.P. for a year in adult patients who underwent total thyroidectomy divided in two groups: those with post-surgical hypocalcemia and without post-surgical hypocalcemia using the 24-hour calcium levels. Urinary output of each patient was verified searching for the relation between this measurement and the probability of developing post-surgical hypoparathyroidism. RESULTS: A total of 47 patients were studied, of whom 19 (40%) were classified with post-surgical hypocalcemia and 28 (59.5%) with no post-surgical hypocalcemia. The urinary output mean on the first 8 hours post-operatory was higher in the post-surgical hypocalcemia group in comparison with the group with no evidence of hypocalcemia, showing no significant difference (p = 0.392). Urinary output 16 hours post-surgical was no significant either (p = 0.435). CONCLUSIONS: In our study, there was no relation found between the increase of the urinary output and the post-surgical hypoparathyroidism prediction. Further studies with a bigger sample and a stronger methodologic design (prospective) are needed to determine if the difference obtained may be useful as a predictor.

Educative Hybrid Intervention as a Strategy for Reintegration to the Clinical Courses of Undergraduate Students in COVID-19 Pandemic.

The SARS-CoV-2 pandemic generated the need to modify the current clinical educational model with the challenge of promoting safety and the continuity of clinical education through the use of virtual platforms. Since clinical training in hospital institutions cannot be substituted, a strategic training plan was developed to guarantee protection, safety, and academic continuity for students upon returning to clinical clerkships. The objective of this project was to develop and evaluate the impact of a massive hybrid training plan as an educative strategy to give the theoretical and practical knowledge required for the safe return of undergraduate students to their respective clinical activities in the context of this pandemic. An academic program was designed through a massive hybrid strategy to train 616 undergraduate students studying clinical cycles by presential, virtual, synchronous, and asynchronous activities. To know the program's impact, a study based on an initial evaluation and a final evaluation was carried out to evaluate the acquisition of the critical knowledge and skills of the program. A significant difference was found between the means of the initial and final evaluations (p <0.001), as well as a high impact of the intervention (d 1.6). Significant improvements in the areas of COVID-19 initial management (p <0.001) and personal protective equipment use (p <0.001) were seen in the post-test when compared to the initial evaluation. Both a quantitative and a qualitative analysis were carried out, finding positive results on the course design, quality of didactic resources, and instructors' performance. Massive hybrid training is an effective strategy to facilitate the reintegration of undergraduate students into their face-to-face clinical rotations.
