Rentabilidad diagnostica de la ecograf铆a comparada con el electromiograma en el s铆ndrome del t煤nel del carpo: revisi贸n sistem谩tica y metaan谩lisis
El objetivo de la presente investigaci贸n fue estimar la rentabilidad
diagn贸stica de la ecogr谩fica comparada al electromiograma en el s铆ndrome del
t煤nel del carpo en poblaci贸n adulta. M茅todos: Revisi贸n sistem谩tica y
metaan谩lisis. Se evaluaron la precisi贸n diagn贸stica de ecograf铆a comparado a la
electromiograf铆a (EMG) para diagnosticar s铆ndrome del t煤nel del capo, en
Scopus, PubMed y otros. La herramienta Quality Assessment of Diagnostic
Accuracy Studies-2 (QUADAS-2), se utiliz贸 para estimar el riesgo de sesgo para
las investigaciones incluidas. Se realiz贸 metaan谩lisis de sensibilidad y
especificidad. Tambi茅n se ha valorado la certeza de la evidencia mediante la
metodolog铆a Grading of Recommendations Assessment, Development, and
Evaluation (GRADE).
Resultados: Se incluyeron un total 5 estudios en esta revisi贸n, que la
rentabilidad diagn贸stica de la ecogr谩fica comparada al electromiograma en STC.
La sensibilidad y la especificidad agrupadas para la ecograf铆a fue una
sensibilidad y especificidad de 92.9% ( 95% IC: 0.875 -0.960) y 87.5% ( 95%
IC: 0.821 -0.914), respectivamente. Para la electromiograf铆a se obtuvo una
sensibilidad y especificidad de 87.0% ( 95% IC: 0.80 - 0.91) y 88.8% (95% IC:
0.81 - 0.93), respectivamente. Se encontr贸 un riesgo intermedio de sesgo, una
moderada heterogeneidad en todos los an谩lisis agrupados y una certeza baja de
la evidencia.
Conclusiones: La ecograf铆a del 谩rea transversal del nervio mediano es 煤til en
la evaluaci贸n diagn贸stica de pacientes con STC como prueba diagn贸stica inicialThe aim of the study was to estimate the diagnostic profitability of
ultrasound compared to electromyogram in carpal tunnel syndrome in adult
population. Methods: Systematic review and metaanalysis. Diagnostic accuracy of
ultrasound compared to electromyography (EMG) was evaluated to diagnose capo
tunnel syndrome in Scopus, PubMed and others. The Quality Assessment of
Diagnostic Accuracy Studies-2 (QUADAS-2) tool was used to estimate the risk of
bias in the included investigations. Sensitivity and specificity meta-analyses were
performed. The certainty of the evidence has also been assessed using the Grading
of Recommendations Assessment, Development, and Evaluation methodology
(GRADE).
Results: A total of 5 studies were included in this review, that the diagnostic
profitability of the ultrasound compared to the electromyogram in STC. The
sensitivity and specificity grouped for ultrasound was a sensitivity and specificity
of 92.9% (95% CI: 0.875 -0.960) and 87.5% (95% CI: 0.821 -0.914), respectively.
For electromyography, sensitivity and specificity were obtained of 87.0% (95% CI:
0.80 - 0.91) and 88.8% (95% CI: 0.81 - 0.93), respectively. A general intermediate
risk of bias was found, a moderate heterogeneity in all the pooled analyses and a
low certainty of the evidence.
Conclusions: Ultrasound of the transverse area of the median nerve is useful in the
diagnostic evaluation of patients with STC as an initial diagnostic testTesi
Condiciones laborales y equipos de protecci贸n personal contra el COVID-19 en personal de salud, Lima-Per煤: Work conditions and personal protective equipment against COVID-19 in health personnel, Lima-Peru
Objective: To determine the association between working conditions and access to personal protective equipment (PPE) in health personnel in the city of Lima-Per煤. Methods: Descriptive, cross-sectional and analytical study. The sample was of 323 respondents virtually in the city of Lima, who met the selection criteria, captured between 07/09/2020 to 08/09/2020. The data collection instrument was validated by expert judgment with a score> 80% (content validity). An analysis was carried out with the generalized linear model of the poisson family, log link function, robust models with fit. A statistically significant value of p <0.05 was considered. Results: 52% of health personnels (HP) worked more than 12 hours and only 55% received one PPE per work day. 50.9% of the HCP almost never received a mask. In the multivariate analysis, the SP with ages <26 years (p=0.00) and from 26 to 55 years (p=0.00) received an incomplete PPE. HP who did not have an employment relationship with the institution (p=0.006) and those who worked in areas with little contact with COVID-19 patients (p=0.022) received a mask on few occasions. Conclusion: Health personnels under 56 years of age rarely received PPE. When they work without an employment relationship and belonged to areas with little contact with COVID-19 patients, they sometimes received a mask.Objetivo: Determinar la asociaci贸n entre las condiciones laborales y el acceso al equipo de protecci贸n personal (EPP) en profesionales de la salud de la ciudad de Lima-Per煤. M茅todos: Estudio descriptivo, transversal y anal铆tico. La muestra fue de 323 encuestados virtualmente en la ciudad de Lima, que cumplieron los criterios de selecci贸n, captados entre el 09/07/2020 al 09/08/2020. El instrumento de recolecci贸n de datos fue validado por juicio de expertos con un puntaje >80% (validez de contenido). Se realiz贸 un an谩lisis con el modelo lineal generalizado de familia Poisson, funci贸n de enlace log, modelos robustos con ajuste. Se consider贸 un valor estad铆sticamente significativo de p<0,05. Resultados: El 52% de los profesionales de la salud (PS) trabajaron m谩s de 12 horas y solo el 55% recibieron un EPP por d铆a de trabajo. El 50,9% del PS casi nunca recibi贸 una mascarilla. En el an谩lisis multivariado el PS con edades <26 a帽os (p=0,00) y de 26 a 55 a帽os (p=0,00) recibieron un EPP incompleto. Los PS que no ten铆an un v铆nculo laboral con la instituci贸n (p=0,006) y los que trabajaban en 谩reas de poco contacto con pacientes COVID-19 (p=0,022) recibieron una mascarilla en pocas oportunidades. Conclusi贸n: Los profesionales de la salud menores de 56 a帽os recibieron con poca frecuencia un EPP. Cuando trabajan sin un v铆nculo laboral y pertenecen a 谩reas de poco contacto con pacientes COVID-19, reciben algunas veces una mascarilla
