Factors Associated with Mortality with Tuberculosis Diagnosis in Indigenous Populations in Peru 2015-2019.

OBJECTIVE: To identify factors associated with mortality in indigenous populations diagnosed with tuberculosis in Peru, 2015-2019. METHODS: We conducted a nested case-control study in a retrospective cohort using the registry of indigenous peoples of the National Health Strategy for TB Prevention and Control of the Ministry of Health of Peru. A descriptive analysis was performed, and then bivariate and multivariate logistic regression was used to evaluate associations between the variables and the outcome (alive-deceased). The results are shown as OR with their respective 95% confidence intervals. RESULTS: The mortality rate of the total indigenous population of Peru was 1.75 deaths per 100,000 indigenous people diagnosed with TB. The community of Kukama Kukamiria-Yagua reported 505 (28.48%) individuals, followed by the Shipibo-Konibo community with 385. The final logistic model showed that indigenous males (OR = 1.93; 95% CI: 1.001-3.7) with a history of HIV prior to TB (OR = 16.7; 95% CI: 4.7-58.7), and indigenous people in old age (OR = 2.95; 95% CI: 1.5-5.7) were factors associated with a greater chance of dying from TB. CONCLUSIONS: It is important to reorient health services among indigenous populations, especially those related to improving a timely diagnosis and early treatment of TB/HIV co-infection, to ensure comprehensive care for this population considering that they are vulnerable groups.

Predictores de fracaso con cánula nasal de alto flujo de oxígeno en pacientes COVID-19 / Predictors of failure with high-flow nasal cannula oxygen in COVID-19 patients

Introducción: El COVID-19 ha generado retos por la alta demanda de servicios, haciendo necesario buscar alternativas de soporte ventilatorio que permitan responder a las necesidades de la población. Es importante disponer de herramientas que permitan detectar precozmente el fracaso de estrategias ventilatorias no invasivas e identificar tempranamente la necesidad de intubación. Objetivo: identificar las variables asociadas a fracaso en el tratamiento con cánula de alto flujo (CNAF) en pacientes con COVID-19. Materiales y Métodos: estudio observacional analítico, corte transversal con 68 pacientes de la unidad de cuidados intensivos con COVID-19, que recibieron tratamiento con CNAF. Las variables de estudio se evaluaron en tres momentos, a las 24, 48 y 72 horas, llevando a cabo un análisis bivariado y multivariado entre los que fracasaron y los que tuvieron éxito. Resultados: en el análisis bivariado las variables que presentaron una relación estadísticamente significativa a las 24h fueron el no presentar un aumento del trabajo respiratorio (Wresp) (p=0.000) y saturación de oxígeno (SatO2) normal (p=0.006). A las 48h: no aumento en Wresp (p=0.014), SatO2 normal (p=0.005), presión arterial de oxígeno/fracción inspirada de oxígeno (PAFI) leve o moderado (p=0.039). A las 72h fracasaron: PAFI severa (p=0.000), aumento de Wresp (p=0.001) y el índice de ROX menor a 4.88 (p=0.023). De acuerdo con el análisis multivariado las variables predictoras de fracaso a las 24h fueron: FIO2, SatO2, Wresp y a las 48h FIO2 y SatO2. Conclusiones: el aumento de FIO2>70 %, presentar incremento del Wresp y SpO2 menor de 88 % son variables asociadas a fracaso de la CNAF y facilitan tomar decisiones clínicas sobre avanzar o no hacia un soporte ventilatorio invasivo.

Introduction: COVID-19 has generated challenges due to the high demand for health care services, making it necessary to seek ventilatory support alternatives that allow us to fulfill the needs of the population. It is important to have tools that allow to detect the failure of non-invasive ventilatory strategies early and to identify the need for intubation on time. Objective: Identify the variables associated with failure of high-flow nasal cannula treatment (HFNC) on COVID-19 patients. Materials and Methods: Analytical observational, cross-sectional study of 68 patients in the intensive care unit with COVID-19, who received treatment with HFNC. The variables of the study were evaluated at three time points, at 24, 48 and 72 hours. A bivariate and multivariate analysis was performed between those who failed and those who were successful. Results: In the bivariate analysis, the variables that presented a statistically significant relationship at 24h were: No increase in work of breathing (WOB) (p=0.000), normal oxygen saturation (SatO2) (p=0.006). At 48h: No increase in WOB (p=0.014), normal SatO2 (p=0.005), mild to moderate partial pressure arterial oxygen/fraction inspired oxygen ratio (P/F ratio) (p=0.039). At 72h failed: severe P/F ratio (p=0.000), Increased WOB (p=0.001) and ROX index less than 4.88 (p=0.023). According to multivariate analysis the predictive variables for the therapeutic failure at 24h were: FIO2, SatO2, WOB; at 48h: FIO2 and SatO2. Conclusions: Increased FIO2>70%, increased WOB and SpO2 less than 88% are variables associated with failure of HFNC, and facilitate clinical decisions on whether or not to progress with invasive ventilatory support.

Tasa de filtración glomerular y deterioro funcional en una unidad geriátrica de agudos / Glomerular filtration rate and functional decline in an acute geriatric unit

RESUMEN Introducción: una tasa baja de Filtración Glomerular estimada (FGe) se asocia con deterioro funcional. Se sabe poco sobre esa asociación en ancianos hospitalizados. Objetivo: determinar si la disminución de la FGe se asocia a deterioro funcional. Metodología: estudio de cohorte prospectiva, incluyó 1826 pacientes mayores de 60 años hospitalizados en Unidad Geriátrica de Agudos, admitidos entre enero de 2012 y agosto de 2015. El desenlace fue el estado funcional evaluado mediante el Índice de Barthel (IB) en cuatro momentos. La función renal fue estimada según MDRD-4, se agruparon en cuatro categorías según FGe (normal ≥90, leve 60-89, moderado 59-30, severo <30). Se usaron modelos de regresión logística multivariada y procedimiento Glimmix para análisis longitudinales. Resultados: edad promedio 82,3±7,2 años, 51 % eran mujeres. En la regresión logística multivariada, un IB≤60 al ingreso estuvo asociado con edad ≥80 años, género femenino, comorbilidad alta, deterioro social, hipoalbuminemia, anemia, MMSE<19; mientras que la falla renal leve o moderada, disminuyen este riesgo. En el análisis longitudinal, la disminución de IB total durante el seguimiento se asoció con edad ≥80 años, género femenino, deterioro social, estancia hospitalaria ≥15 días, comorbilidad alta, hipoalbuminemia y MMSE <19. La presencia de falla renal leve, moderada o severa se asoció con mayor IB a través del tiempo. Conclusiones: una disminución de FGe está asociada con bajo riesgo de deterioro funcional al ingreso y al seguimiento. Estos hallazgos difieren de reportes previos en la literatura.

SUMMARY Introduction: Low estimated Glomerular filtration rate (eGFR) is associated with functional decline. Little is known on that association in hospitalized elderly. Objective: Determine if low eGFR is associated with functional decline. Methods: Prospective cohort study that included 1826 patients 60 years and older hospitalized in a Geriatric Acute Unit, admitted between January 2012 and August 2015. The outcome was functional status assessed four times by the Barthel Index (BI). Kidney function was estimated by MDRD-4 IDMS and was grouped into four categories according to eGFR (normal ≥90, mild 60-89, moderate 59-30, severe <30). Multivariate logistic regression models and GLIMMIX procedure for longitudinal analyzes were used. Results: Mean age was 82.3±7.2 years, 51 % were women. In multivariate logistic regression, a BI≤60 at admission was associated with age ≥80, female gender, high comorbidity, social deterioration, hypoalbuminemia, anemia, MMSE<19, while the presence of mild or moderate renal failure reduced this risk. In the longitudinal analysis, lower total BI at follow-up was associated with age ≥80, female gender, social deterioration, hospital stay ≥15 days, high comorbidity, hypoalbuminemia, MMSE<19. The presence of mild, moderate or severe renal impairment was associated with higher BI over time. Conclusions: A low eGFR was associated with lower risk for functional decline at admission and overtime. These findings differ from previous reports in the literature.
