ABSTRACT
Abstract To evaluate the effectiveness of an anticoagulation protocol adapted in a mobile application (appG) for patients using warfarin. This was a cluster randomized controlled clinical trial carried out in basic health centers of Ijui, RS, Brazil, between April and October 2017. The appG was installed on the cell phones of all physicians belonging to the intervention group. Primary outcomes were bleeding and thrombosis, and secondary outcomes were changes in the dose of warfarin, use of new drugs, drug interactions, search for health services, and remaining on the target international normalized ratio. Thirty-three patients belonging to 11 basic health centers were included in this study. From these, 15 patients were in the intervention group which used the appG, and 18 were in the control group. After 6 months, patients in the appG group had fewer bleeding events (7% versus 50%, p-value=0.028) and a lower weekly dose of warfarin (29.3 ± 9.7 mg versus 41.7 ± 12.5 mg, p-value=0.030) when compared to the control group. The anticoagulation protocol adapted in a mobile app reduced bleeding in patients using warfarin.

RESUMEN El vínculo entre Hipertensión Arterial (HTA) y Enfermedad Renal Crónica (ERC) es recíproco y complejo. La HTA es un factor de riesgo reconocido para el desarrollo de ERC, y la incidencia de enfermedad renal se incrementa conforme aumenta la severidad de la HTA. Adicionalmente la presencia de HTA se vincula a progresión de la ERC desde etapas tempranas hasta el desarrollo de ERC-extrema. La presencia de HTA enmascarada, HTA de túnica blanca y la pérdida del patrón dipping nocturno se vinculan a desarrollo y progresión de enfermedad renal. El tamizaje de ERC es recomendado para pacientes con HTA en riesgo de desarrollar la enfermedad. Es más discutido si debe realizarse tamizaje en individuos con bajo riesgo de desarrollar ERC. Las cifras objetivo de presión arterial en este grupo de pacientes son sugeridas por las guías KDIGO. Múltiples estudios han buscado identificar si el control intensivo de presión arterial disminuye la incidencia de ERC y su progresión pero los resultados no son concluyentes. El presente trabajo revisa el vínculo entre HTA y desarrollo y progresión de la ERC. Se puntualiza sobre la población con HTA que se beneficia del tamizaje de ERC y los valores objetivo de presión arterial en este grupo.
ABSTRACT The link between Arterial Hypertension (AHT) and Chronic Renal Disease (CKD) is reciprocal and complex. HBP is a recognized risk factor for the development of CKD, and the incidence of renal disease increases as the severity of hypertension increases. Additionally, the presence of hypertension is linked to progression of CKD from early stages to the development of extreme-ERC. The presence of masked HTA, white tunica HTA and loss of nocturnal dipping pattern are associated with development and progression of renal disease. Screening for CKD is recommended for patients with hypertension at risk of developing the disease. It is more controversial whether screening should be done in individuals at low risk of developing CKD. The target blood pressure figures in this group of patients are suggested by the KDIGO guidelines. Multiple studies have sought to identify whether intensive blood pressure control decreases the incidence of CKD and its progression but the results are inconclusive. This paper reviews the link between hypertension and development and progression of CKD. It is pointed out the population with hypertension that benefits from CKD screening and target blood pressure values in this group.
