ObjectiveTo describe mortality of in-hospital patients with COVID-19 and compare risk factors between survivors and non-survivors.DesignProspective cohort of adult inpatients.SettingTertiary healthcare teaching hospital in Guadalajara, Mexico.ParticipantsAll patients with confirmed COVID-19 hospitalised from 25 March to 7 September 2020 were included. End of study: 7 November 2020.Primary outcome measuresPatient survival analysed by the Kaplan-Meier method and comparison of factors by the log-rank test. Mortality risk factors analysed by multivariate Cox’s proportional-hazard model.ResultsOne thousand ten patients included: 386 (38%) died, 618 (61%) alive at discharge and six (0.6%) remained hospitalised. There was predominance of men (63%) and high frequency of overweight–obesity (71%); hypertension (54%); diabetes (40%); and lung (9%), cardiovascular (8%) and kidney diseases (11%); all of them significantly more frequent in non-survivors. Overweight–obesity was not different between groups, but severity of disease (Manchester Triage System and quick Sequential Organ Failure Assessment) was significantly worse in non-survivors, who were also significantly older (65 vs 45 years, respectively) and had haematological, biochemical, coagulation and inflammatory biomarkers more altered than survivors. Mortality predictors were invasive mechanical ventilation (IMV; OR 3.31, pConclusionsMortality in hospitalised patients with COVID-19 in this emerging country centre seemed to be higher than in developed countries. Patients displayed a high frequency of risk factors for poor outcome, but the need for IMV, ICU admission, older age, more severe disease at admission, antecedent of kidney disease and higher CRP levels significantly predicted mortality.

Aims: The influence of the COVID-19 pandemic on attendance to out-of-hospital cardiac arrest (OHCA) has only been described in city or regional settings. The impact of COVID-19 across an entire country with a high infection rate is yet to be explored. Methods: The study uses data from 8629 cases recorded in two time-series (2017/2018 and 2020) of the Spanish national registry. Data from a nonCOVID-19 period and the COVID-19 period (February 1st-April 30th 2020) were compared. During the COVID-19 period, data a further analysis comparing non-pandemic and pandemic weeks (defined according to the WHO declaration on March 11th, 2020) was conducted. The chi-squared analysis examined differences in OHCA attendance and other patient and resuscitation characteristics. Multivariate logistic regression examined survival likelihood to hospital admission and discharge. The multilevel analysis examined the differential effects of regional COVID-19 incidence on these same outcomes. Results: During the COVID-19 period, the incidence of resuscitation attempts declined and survival to hospital admission (OR = 1.72; 95%CI = 1.46-2.04; p < 0.001) and discharge (OR = 1.38; 95%CI = 1.07-1.78; p = 0.013) fell compared to the non-COVID period. This pattern was also observed when comparing non-pandemic weeks and pandemic weeks. COVID-19 incidence impinged significantly upon outcomes regardless of regional variation, with low, medium, and high incidence regions equally affected. Conclusions: The pandemic, irrespective of its incidence, seems to have particularly impeded the pre-hospital phase of OHCA care. Present findings call for the need to adapt out-of-hospital care for periods of serious infection risk. Study registration number: ISRCTN10437835.

To determine the prevalence of cardiovascular risk factors (CVRF) in healthcare workers from two tertiary-care hospitals of the Mexican Institute of Social Security, as well as their association with professional activities (PA).Descriptive study. One-thousand eighty-nine health-care workers ≥ 18 years were included. Clinical history, physical exam, and blood tests were performed.Mean age 41 ± 9 years, 76% women. Hypertension prevalence was 19%, diabetes mellitus 9.6%, dyslipidemia 78%, overweight and obesity 73%, metabolic syndrome (MS) 32.5%, and smoking 19%. The following significant associations (p0.05) were found: MS with medical asisstants (OR: 2.73, CI 95%: 1.31-5.69) and nutritionist (OR: 2.6, CI 95%: 1.31-5.24); obesity with administrative personnel (OR: 3.64, CI 95%: 1.40-7.46); dyslipidemia with medical asisstants (OR: 2.58, CI 95%: 1.15-6.34). In the whole sample, the probability to have a vascular event in the following 10 years was 10%.Prevalence of CVRF was high in this sample of health-care workers and did not seem to be different from those in general population. Medical assistants, nutritionist, and administrative personnel displayed a higher risk. It is necessary to create programs to promote healthy lifestyle and to improve the epidemiological profile of health-care workers.Introducción: el objetivo de este trabajo es determinar la prevalencia de los factores de riesgo cardiovascular (FRCV) y su asociación con actividad laboral (AL) en trabajadores de dos hospitales de enseñanza de tercer nivel de atención del IMSS. Métodos: estudio descriptivo que incluyó a trabajadores ≥ 18 años. Se realizó historia clínica, examen físico y pruebas de laboratorio para identificar FRCV y asociarlos con AL. Resultados: se estudió un total de 1089 trabajadores, con edad de 41 ± 9 años, el 76% fueron mujeres. La prevalencia de hipertensión fue de 19%, diabetes mellitus 9.6%, dislipidemia 78%, sobrepeso y obesidad 73%; síndrome metabólico (SM) 32.5%, tabaquismo 19%. El SM se asoció con el área de asistentes médicas (OR: 2.73, IC 95%: 1.31-5.69) y nutrición/dietética (OR: 2.6, IC 95%: 1.31-5.24). La obesidad con el área administrativa (OR 3.64 IC 95%: 1.40-7.46). La dislipidemia con el área de asistentes médicas (OR 2.58, IC 95%: 1.15-6.34). La probabilidad de sufrir evento vascular en 10 años fue de 10%. Conclusiones: la prevalencia de FRCV fue alta y no es diferente a la de la población general. Las actividades laborales en riesgo fueron: asistentes médicas, nutricionistas y personal administrativo. Es necesario reorientar programas de promoción de la salud en unidades médicas para mejorar el perfil epidemiológico de los trabajadores.
