Epidemiological profile of venous thrombosis in the Mexican Republic from 2016 to 2018.

OBJECTIVE: This study aims to analyze the probability of an increase in mortality due to venous thrombosis of the lower limbs (VTLL), and it´s relation to days of hospital stay. MATERIALS AND METHODS: We included all hospital records of patients with thrombosis in the lower limbs as main diagnosis from open access national datasets, we obtained epidemiological description of diagnosis, length of stay and mortality. RESULTS: Deep vein thrombosis (DVT) constituted 69% (1223/1785) of cases. From all the patients registered, 47 (2.63%) died. The highest mortality rate was observed in older adults, and patients with a longer hospital stay. CONCLUSIONS: Patients diagnosed with DVT, who endure a longer hospital stay, face a major risk of death.

OBJETIVO: Analizar la probabilidad de un aumento de la mortalidad por trombosis venosa de miembros inferiores (TVMI) y su relación con los días de estancia hospitalaria. MATERIAL Y MÉTODOS: Se incluyeron los registros de egreso hospitalario con el diagnóstico de VTLL, obtenido de las bases de datos de los hospitales públicos de México. RESULTADOS: El diagnóstico más frecuente fue la trombosis venosa profunda (TVP) con el 69% (1223/1785) de los casos. Del total de casos se registraron 47 (2.63%) muertes, la mortalidad fue más alta a mayor edad y estancia hospitalaria. CONCLUSIONES: Los pacientes diagnosticados por TVP y con estancia hospitalaria prolongada, presentaron mayor mortalidad.

Influenza in Yucatan in 2018: Chronology, characteristics and outcomes of ambulatory and hospitalized patients.

INTRODUCTION: Influenza season is expected between October and February in the northern hemisphere, including Mexico. Previous studies suggested that transmission peak may occur earlier in Yucatan, a state in southeast Mexico. OBJECTIVES: (a) Describe the seasonality of 2018 influenza cases seen at O´Horan hospital, statewide, and nationwide; (b) analyze the characteristics, clinical manifestations and outcomes of ambulatory and hospitalized patients; (c) analyze fatal outcomes occurrence among vaccinated and unvaccinated individuals. METHODS: Retrospective analytic cohort of all confirmed influenza cases assisted at O´Horan hospital during 2018, along with a chronologic graphic description of the statewide epidemic curve from the epidemiological surveillance registries. RESULTS: A total of 264 influenza cases were analyzed; 145 (55%) were female; 26% were vaccinated. Health workers and unvaccinated individuals were more prone to develop severe cases. Dyspnea and tachypnea were strong predictors of hospitalization; headache, myalgias, arthralgias and rhinorrhea correlated inversely. 236 (89.47%) cases occurred in July and 22 of the 23 deaths occurred before October. No fatal outcomes were observed among vaccinated individuals. Influenza AH1N1 represented 83.6% of serotyped cases. DISCUSSION: Onset of influenza season in Yucatan may reflect a need for rethinking timing of vaccination and of preventive campaigns, as most cases occurred before vaccination period.
