Abstract Introduction: The control and evaluation of glycemic levels in critically ill patients is a challenge and a responsibility of the nursing team; therefore, determining the consequences of this during hospitalization is key to demonstrate the importance of timely management. Objective: To determine the relationship between unstable glycemia (hyperglycemia and hypoglycemia), hospital length of stay, and the hospitalization outcome of patients in an Intensive Care Unit (ICU). Methods: A prospective cohort study conducted with 62 critically ill patients by convenience sampling between March and July 2017. Daily blood samples were collected to measure glycemia. The correlation of unstable glycemia with the hospital length of stay and the hospitalization outcome was assessed using Pearson's chi-square. A p-value <0.05 was considered significant. Results: Among the 62 patients, 50% were male and 50% were female. The mean age was 63.3 years (±21.4 years). The incidence of unstable glycemia was 45.2% and was associated with a longer ICU stay (p<0.001) and a progression to death as a hospitalization outcome (p=0.03). Conclusion: Among critically ill patients, unstable glycemia was associated with an extended hospital length of stay and a progression to death, emphasizing the importance of nursing intervention to prevent its occurrence.

Sarcopenia measured by tomography as a predictor of morbidity and mortality in thoracic surgery, a retrospective cohort study.

BACKGROUND: Sarcopenia has been identified as a risk factor for perioperative adverse events. Several studies have shown that tomographic assessment of muscle mass can be an appropriate indicator of sarcopenia associated with morbidity and mortality. The aim of the study was to determine the association between height-adjusted area of ​​the pectoral and erector spinae muscles (haPMA and haESA) and perioperative morbidity and mortality in thoracic surgery. METHODS: Retrospective cohort study. Measurement of muscle areas was performed by tomography. The outcomes were 30-day mortality and postoperative morbidity. The discriminative capacity of the muscle areas was evaluated with an analysis of ROC curves and the Youden index was used to establish a cut-off point. The raw morbidity and mortality risk was determined and adjusted for potential confounders. RESULTS: A total of 509 patients taken to thoracic surgery were included. The incidence of 30-day mortality was 7.3%. An association was found between muscle areas and 30-day mortality and pneumonia, with adequate discriminative power for mortality (AUC 0.68 for haPMA and 0.67 for haESA). An haPMA less than 10 and haESA less than 8.5 cm2/m2 were identified as a risk factor for 30-day mortality with an adjusted OR of 2.34 (95%CI 1.03-5.15) and 2.22 (95%CI 1.10-6.04) respectively. CONCLUSIONS: Sarcopenia, defined as low muscle area in the pectoral and erector spinae muscles, is associated with increased morbidity and mortality in patients undergoing thoracic surgery.

Mortalidad, Secuelas Clínicas y Calidad de Vida Luego del Alta de Unidades de Cuidados Intensivos en Pacientes con COVID-19: Estudio Multicéntrico Descriptivo en Argentina.

OBJECTIVE: Patients with COVID-19 who require hospitalization in an intensive care unit, in addition to being at risk of presenting premature death, have higher rates of complications. This study aimed to describe mortality, rehospitalizations, quality of life, and symptoms related to postintensive care syndrome (PICS) and prolonged COVID-19 in patients with COVID-19 discharged from the intensive care unit in hospitals in Argentina. METHODS: A cross-sectional study was conducted in 4 centers in the Autonomous City and province of Buenos Aires as of December 2022. The variables of interest were mortality after discharge, rehospitalization, health-related quality of life, post-COVID-19-related symptoms, cognitive status, and PICS. Data collection was by telephone interview between 6 and 18 months after discharge. RESULTS: A total of 124 patients/families were contacted. Mortality was 7.3% (95% CI: 3.87-13.22) at 14.46 months of follow-up after discharge. Patients reported a reduction of the EQ-5D-3L visual analog scale of 13.8 points, reaching a mean of 78.05 (95% CI: 73.7-82.4) at the time of the interview. Notably, 54.4% of patients (95% CI: 41.5-66.6) reported cognitive impairment and 66.7% (95% CI: 53.7-77.5) developed PICS, whereas 37.5% (95% CI: 26-50.9) had no symptoms of prolonged COVID-19. CONCLUSION: The results showed a significant impact on the outcomes studied, consistent with international evidence.

Rising testicular cancer incidence in Spain despite declining mortality: an age-period-cohort analysis.

BACKGROUND: Testicular cancer, primarily affecting young men, has seen an alarming rise globally. This study delves into incidence and mortality trends in Spain from 1990 to 2019 using the Global Burden of Disease (GBD) database and the Age-Period-Cohort (A-P-C) model. METHODS: We analyzed GBD data on testicular cancer cases and deaths in Spain, calculating age-standardized rates (ASIR and ASMR) and employing Joinpoint regression to identify significant shifts. The A-P-C model further dissected the effects of age, period, and birth cohort on these trends. RESULTS: A striking doubling in testicular cancer incidence was observed, from 3.09 to 5.40 per 100,000 men (1.9% annual increase), while mortality rates remained stable and even decreased in younger age groups (0.34 to 0.26 per 100,000, 0.8% annual decrease). Joinpoint analysis revealed four distinct periods of increasing incidence, with a recent slowdown. The A-P-C model highlighted a consistent rise in incidence risk with each successive generation born after 1935, contrasting with a progressive decline in mortality risk across cohorts, particularly marked for those born since the 1960s. CONCLUSION: While mortality rates are encouraging, Spain reflects the global trend of escalating testicular cancer incidence. The A-P-C analysis suggests a generational influence, but the underlying causes remain elusive. Further research is crucial to understand these trends and implement effective prevention strategies to combat this growing health concern.

Objetivo Describir y caracterizar una cohorte de pacientes octogenarios ingresados en la UCI del Hospital Universitario Central de Asturias (HUCA). Diseño Estudio retrospectivo, observacional y descriptivo de 14 meses de duración. Ámbito Unidad de Cuidados Intensivos (UCI) Cardiaca y UCI Polivalente del Servicio de Medicina Intensiva del HUCA (Oviedo). Participantes Pacientes mayores de 80 años que ingresaron en la UCI durante más de 24 horas.Intervenciones Ninguna. Variables de interés principales Edad, sexo, comorbilidad, capacidad funcional, tratamiento, complicaciones, evolución, mortalidad. Resultados Los motivos de ingreso más frecuentes fueron la cirugía cardiaca y la neumonía. La estancia media de ingreso fue significativamente mayor en pacientes menores de 85 años (p=0,037). El 84,3% de estos últimos se benefició de ventilación mecánica invasiva (VMI) vs. 46,2% de los pacientes más mayores (p=<0,001). Los pacientes mayores de 85 años presentaron mayor fragilidad. El ingreso por intervención quirúrgica cardiaca se asoció con menor riesgo de mortalidad (hazard ratio [HR]=0,18; intervalo de confianza [IC] 95%, 0,062-0,527; p=0,002). Conclusiones Los resultados muestran una asociación entre el motivo de ingreso en UCI y el riesgo de mortalidad en pacientes octogenarios. La cirugía cardiaca se asoció con mejor pronóstico frente a la patología médica, donde la neumonía se asoció con mayor riesgo de mortalidad. Además, se observó una relación positiva significativa entre edad y fragilidad. (AU)

ObjectiveTo describe and characterize a cohort of octogenarian patients admitted to the ICU of the University Central Hospital of Asturias (HUCA). Design Retrospective, observational and descriptive study of 14 months’ duration. Setting Cardiac and Medical Intensive Care Units (ICU) of the HUCA (Oviedo). Participants Patients over 80 years old who were admitted to the ICU for more than 24hours. Interventions None. Main variables of interest Age, sex, comorbidity, functional dependence, treatment, complications, evolution, mortality. Results The most frequent reasons for admission were cardiac surgery and pneumonia. The average admission stay was significantly longer in patients under 85 years of age (p=0,037). 84,3% of the latter benefited from invasive mechanical ventilation compared to 46,2% of older patients (p=<0,001). Patients over 85 years of age presented greater fragility. Admission for cardiac surgery was associated with a lower risk of mortality (HR=0,18; 95% CI (0,062-0,527; p=0,002). Conclusions The results have shown an association between the reason for admission to the ICU and the risk of mortality in octogenarian patients. Cardiac surgery was associated with a better prognosis compared to medical pathology, where pneumonia was associated with a higher risk of mortality. Furthermore, a significant positive association was observed between age and frailty. (AU)

Morbidity and mortality of elderly patients with pancreaticobiliary disease according to age and comprehensive geriatric assessment: A prospective observational study / Morbilidad y mortalidad de pacientes de edad avanzada con enfermedad pancreaticobiliar con relación a su edad y la evaluación geriátrica integral: un estudio prospectivo observacional

Background This study was designed to analyze the influence of age and comprehensive geriatric evaluation on clinical results of pancreaticobiliary disease management in elderly patients. Methods A prospective observational study has been undertaken, including 140 elderly patients (over 75 years) with benign pancreaticobiliary disease. Patients were divided according to age in the following groups: group 1: 75–79 years old; group 2: 80–84 years old; group 3: 85 years and older. They underwent a comprehensive geriatric assessment with different scales: Barthel Index, Pfeiffer Index, Charlson Index, and Fragility scale, at admission and had been follow-up 90 days after hospital discharge to analyze its influence on morbidity and mortality. Results Overall, 140 patients have been included (group 1=51; group 2=43 and group 3=46). Most of them, 52 cases (37.8%), had acute cholecystitis, followed by 29 cases of acute cholangitis (20.2%) and acute pancreatitis with 25 cases (17.9%). Significant differences has been observed on complications in different age groups (p=0.033). Especially in patients with a Barthel Index result ≤60, which suggests that these less functional patients had more severe complications after their treatment (p=0.037). The mortality rate was 7.1% (10 patients). Conclusions No significant differences were found between age, morbidity and mortality in elderly patients with pancreaticobiliary disease. Comprehensive geriatric scales showed some utility in their association with specific complications. (AU)

Antecedentes Este estudio fue diseñado para analizar la influencia de la edad y la evaluación geriátrica integral en los resultados clínicos del manejo de la enfermedad pancreatobiliar en pacientes de edad avanzada. Métodos Se ha realizado un estudio observacional prospectivo en el que se incluyeron 140 pacientes de edad avanzada (mayores de 75 años) con enfermedad pancreatobiliar benigna. Los pacientes se dividieron según la edad en los siguientes grupos: Grupo 1: 75-79 años; Grupo 2: 80-84 años; Grupo 3: 85 años y más. Se les realizó una valoración geriátrica integral con diferentes escalas: Barthel Index, Pfeiffer Index, Charlson Index y Fragility scale, al ingreso y seguimiento 90 días después del alta hospitalaria para analizar su influencia en la morbimortalidad. Resultados En total, se incluyeron 140 pacientes (Grupo 1=51; Grupo 2=43 y Grupo 3=46). La mayoría de ellos, 52 casos (37,8%), presentaron colecistitis aguda, seguido de colangitis aguda con 29 casos (20,2%) y pancreatitis aguda con 25 casos (17,9%). Se han observado diferencias significativas en las complicaciones en diferentes grupos de edad (p=0,033). Especialmente en pacientes con un índice de Barthel ≤60, lo que sugiere que estos pacientes menos funcionales tuvieron complicaciones más severas después de su tratamiento (p=0,037). La tasa de mortalidad fue de 7,1% (10 pacientes). Conclusiones No se encontraron diferencias significativas entre la edad, la morbilidad y la mortalidad en pacientes ancianos con enfermedad pancreatobiliar. Las escalas geriátricas integrales mostraron cierta utilidad en su asociación con complicaciones específicas. (AU)

Critical pregnancy at altitude: A look at Latin America.

Critical pregnancy at high altitudes increases morbidity and mortality from 2500 m above sea level. In addition to altitude, there are other influential factors such as social inequalities, cultural, prehospital barriers, and lack the appropriate development of healthcare infrastructure. The most frequent causes of critical pregnancy leading to admission to Intensive Care Units are pregnancy hypertensive disorders (native residents seem to be more protected), hemorrhages and infection/sepsis. In Latin America, there are 32 Intensive Care Units above 2500 m above sea level. Arterial blood gases at altitude are affected by changes in barometric pressure. The analysis of their values provides very useful information for the management of obstetric emergencies at very high altitude, especially respiratory and metabolic pathologies.

Comparative analysis of foetal and neonatal growth curves.

INTRODUCTION: Our aim was to determine which foetal or neonatal growth curves discriminate the probability of dying of newborns with low birth weight for their gestational age (small for gestational age, SGA) and sex (weight < 10th percentile) and to establish the curves that are presumably most useful for monitoring growth through age 10 years. MATERIAL AND METHODS: The analysis included every neonate (15 122) managed in our hospital (2013-2022) and all neonates born preterm before 32 weeks (6913) registered in the SEN1500 database (2019-2022). We considered most useful those curves with the highest likelihood ratio (LR) for dying with or without a history of SGA in each subgroup of gestational ages. Theoretically, the optimal curves for monitoring growth would be those with a higher R2 in the quantile regression formulas for the 50th percentile. RESULTS: The growth curves exhibiting the strongest association between SGA and hospital mortality are the Intergrowth fetal curves and the Fenton neonatal curves in infants born preterm before 32 weeks. However, the optimal curves for premature babies and neonates overall were those of Olsen and Intergrowth. The most useful curves to monitor anthropometric values alone until age 10 years of age are the longitudinal Intergrowth curves followed by the WHO standards, but if a single reference is desired from birth through age 10 years, the best option is the Fenton curves followed by the WHO standards. CONCLUSIONS: The Intergrowth reference provides the most discriminating foetal growth curves. In neonatal clinical practice, the optimal references are the Fenton followed by the WHO charts.

Mortality attributable to secondhand smoke exposure in the autonomous communities of Spain.

INTRODUCTION AND OBJECTIVES: Exposure to secondhand smoke (SHS) causes cardiovascular disease, respiratory disease, and cancer. The aim of this study was to estimate the mortality attributed to SHS in people aged ≥ 35 years in Spain and its autonomous communities (AC) by sex from 2016 to 2021. METHODS: Estimates of SHS-attributable mortality were calculated by applying the prevalence-dependent method where SHS exposure was derived from the adjustment of small-area models and based on the calculation of population-attributed fractions. Sex, age group, AC, and cause of death (ischemic heart disease and lung cancer) were included. The estimates of attributed mortality are presented with their 95% confidence interval (95%CI). Crude and age-standardized rates were estimated for each sex and AC. RESULTS: From 2016 to 2021, SHS exposure caused 4,970 (95%CI, 4,787-5,387) deaths, representing 1.6% of total mortality for ischemic heart disease and lung cancer. The burden of attributed mortality differed widely among the AC, with Andalusia having the highest burden of attributed mortality (crude rate: 46.6 deaths per 100 000 population in men and 17.0/100 000 in women). In all the AC, the main cause of death in both sexes was ischemic heart disease. The highest burden of mortality was observed in nonsmokers. CONCLUSIONS: The burden of SHS-attributable mortality was high and varied geographically. The results of this study should be considered to advance tobacco control legislation in Spain.

Aspectos epidemiológicos, manejo clínico y resultados a corto plazo en pacientes mayores diagnosticados de insuficiencia cardiaca aguda en urgencias en España: resultados del estudio EDEN-34 / Epidemiological aspects, clinical management and short-term outcomes in elderly patients diagnosed with acute heart failure in the emergency department in Spain: results of the EDEN-34 study

Objetivo: Estimar la incidencia de diagnóstico de insuficiencia cardiaca aguda (ICA) en pacientes mayores en los servicios de urgencias (SU), la confirmación diagnóstica de la ICA en pacientes hospitalizados y los eventos adversos a corto plazo. Método: Se incluyeron a todos los pacientes de ≥65 años atendidos en 52 SU españoles durante una semana y se seleccionaron los diagnosticados de ICA. En los hospitalizados se recogieron los diagnosticados de ICA al alta. Como eventos adversos, se recogió la mortalidad intrahospitalaria y a 30 días, y evento adverso combinado (muerte u hospitalización) a 30 días posalta. Se calcularon las odds ratio (OR) ajustadas de las características demográficas, de estado basal y a la llegada al SU asociadas con mortalidad y evento adverso posalta a 30 días. Resultados: Se incluyeron 1.155 pacientes con ICA (incidencia anual: 26,5 por 1.000 habitantes ≥65 años, IC95%: 25,0-28,1). En el 86%, el diagnóstico de ICA constaba al alta. La mortalidad global a 30 días fue del 10,7%, la intrahospitalaria del 7,9% y el evento combinado posalta del 15,6%. La mortalidad intrahospitalaria y a 30 días se asoció con hipotensión arterial (OR ajustada: 74,0, IC95%: 5,39-1.015.; y 42,6, 3,74-485, respectivamente) e hipoxemia (2,14, 1,27-3,61; y 1,87, 1,19-2,93) a la llegada a urgencias y con precisar ayuda en la deambulación (2,24, 1,04-4,83; y 2,48, 1,27-4,86) y la edad (por cada incremento de 10 años; 1,54, 1,04-2,29, y 1,60, 1,13-2,28). Conclusiones: La ICA es un diagnóstico frecuente en los pacientes mayores que consultan en los SU. El deterioro funcional, la edad, la hipotensión e hipoxemia son los factores que más se asocian a mortalidad.(AU)

Objective: To estimate the incidence of acute heart failure (AHF) diagnosis in elderly patients in emergency departments (ED), diagnostic confirmation in hospitalized patients, and short-term adverse events. Methods: All patients aged ≥65 years attended in 52 Spanish EDs during 1 week were included and those diagnosed with AHF were selected. In hospitalized patients, those diagnosed with AHF at discharge were collected. As adverse events, in-hospital and 30-day mortality, and combined adverse event (death or hospitalization) at 30 days post-discharge were collected. Adjusted odds ratios (OR) for association of demographic variables, baseline status and constants at ED arrival with mortality and 30-day post-discharge adverse event were calculated. Results: We included 1,155 patients with AHF (annual incidence: 26.5 per 1000 inhabitants ≥65 years, 95%CI: 25.0-28.1). In 86% the diagnosis of AHF was known at discharge. Overall 30-day mortality was 10.7% and in-hospital mortality was 7.9%, and the combined event in 15.6%. In-hospital and 30-day mortality was associated with arterial hypotension (adjusted OR: 74.0, 95%CI: 5.39-1015. and 42.6, 3.74-485, respectively and hypoxemia (2.14, 1.27-3.61; and 1.87, 1.19-2.93) on arrival at the ED and requiring assistance with ambulation (2.24, 1.04-4.83; and 2.48, 1.27-4.86) and age (per 10-year increment; 1.54, 1.04-2.29; and 1.60, 1.13-2.28). The combined post-discharge adverse event was not associated with any characteristic. Conclusions: AHF is a frequent diagnosis in elderly patients consulting in the ED. The functional impairment, age, hypotension and hypoxemia are the factors most associated with mortality.(AU)

Prognostic value of anti-IFI16 autoantibodies in pulmonary arterial hypertension and mortality in patients with systemic sclerosis / Valor pronóstico de los autoanticuerpos anti-IFI16 en la hipertensión arterial pulmonar y en la mortalidad en los pacientes con esclerodermia sistémica

Objectives: To determine the diagnostic value of anti-interferon gamma inducible protein 16 (IFI16) autoantibodies in systemic sclerosis (SSc) patients negative for all tested SSc-specific autoantibodies (SSc-seronegative patients) and to evaluate the clinical significance of these autoantibodies, whether isolated or in the presence of anti-centromere autoantibodies (ACA). Methods: Overall, 58 SSc-seronegative and 66 ACA-positive patients were included in the study. All patients were tested for anti-IFI16 autoantibodies by an in-house direct ELISA. Associations between clinical parameters and anti-IFI16 autoantibodies were analysed. Results: Overall, 17.2% of SSc-seronegative and 39.4% of ACA-positive patients were positive for anti-IFI16 autoantibodies. Anti-IFI16 autoantibodies were found only in patients within the limited cutaneous SSc (lcSSc) subset. A positive association between anti-IFI16 positivity and isolated pulmonary arterial hypertension (PAH) was found (odds ratio [OR]=5.07; p=0.014) even after adjusting for ACA status (OR=4.99; p=0.019). Anti-IFI16-positive patients were found to have poorer overall survival than negative patients (p=0.032). Cumulative survival rates at 10, 20 and 30 years were 96.9%, 92.5% and 68.7% for anti-IFI16-positive patients vs. 98.8%, 97.0% and 90.3% for anti-IFI16-negative-patients, respectively. Anti-IFI16-positive patients also had worse overall survival than anti-IFI16-negative patients after adjusting for ACA status in the multivariate Cox analysis (hazard ratio [HR]=3.21; p=0.043). Conclusion: Anti-IFI16 autoantibodies were associated with isolated PAH and poorer overall survival. Anti-IFI16 autoantibodies could be used as a supplementary marker of lcSSc in SSc-seronegative patients and for identifying ACA-positive patients with worse clinical outcome. (AU)

Objetivos: Determinar el valor diagnóstico de los autoanticuerpos anti-interferon gamma inducible protein 16 (IFI16) en los pacientes con esclerodermia sistémica (SSc) negativos para todos los autoanticuerpos específicos de SSc (pacientes SSc seronegativos) y evaluar el significado clínico de estos autoanticuerpos, aislados o en combinación con autoanticuerpos anticentrómero (ACA). Métodos: Se incluyeron 58 pacientes SSc seronegativos y 66 pacientes ACA positivos. Todos los pacientes se testaron para los autoanticuerpos anti-IFI16 mediante un ELISA directo «in-house». Las asociaciones entre parámetros clínicos y los autoanticuerpos anti-IFI16 fueron analizadas. Resultados: En total, el 17,2% de los pacientes SSc seronegativos y el 39,4% de los pacientes ACA positivos fueron positivos para anti-IFI16. Los autoanticuerpos anti-IFI16 se detectaron solamente en los pacientes con la forma limitada cutánea de SSc (lcSSc). Se encontró una asociación entre la positividad de anti-IFI16 y la hipertensión arterial pulmonar (HAP) aislada (odds ratio [OR]: 5,07; p=0,014), incluso cuando se ajustó el análisis a la presencia o ausencia de ACA (OR: 4,99; p=0,019). Los pacientes anti-IFI16 positivos mostraron una peor supervivencia general que los pacientes negativos (p=0,032). Las ratios de supervivencia acumulada a 10, 20 y 30 años fueron respectivamente del 96,9, 92,5 y 68,7% para los pacientes anti-IFI16 positivos frente al 98,8, 97,0 y 90,3% para los anti-IFI16 negativos. Los pacientes anti-IFI16 positivos también tenían una supervivencia general menor que los pacientes anti-IFI16 negativos tras ajustar para la presencia o ausencia de ACA mediante análisis multivariado de Cox (hazard ratio [HR]: 3,21; p=0,043)...

Risk factors and mortality of candidemia in a children's public hospital in Sao Paulo, Brazil.

Candida bloodstream infections in children are of special concern in neonatal and pediatric intensive care and patients with comorbidities. This study aimed to estimate the incidence and risk factors associated with mortality in candidemia cases occurring in a public children's hospital in Ribeirao Preto, Brazil. It is a retrospective transversal study. Every patient under the age of 18 admitted to the study facility from January 1, 2013, to December 31, 2019, was considered potentially eligible to be included if they had candidemia. We collected clinical data from medical records. We included 113 blood cultures yielding positive results for Candida. The incidence rate was 2.12 per 1000 admissions. The most common Candida species was Candida parapsilosis. Septic shock during the candidemia episode was the only clinical outcome associated with a relative risk-adjusted (RRa) of 2.77 with an interval >1 (1.12-6.85). Our findings show that the incidence rate and mortality rates of candidemia are in line with those in other children's services in Brazil. We found a global mortality rate of 28.31% (32/113) from candidemia episodes. We highlight the predominance of non-albicans Candida species including C. parapsilosis. Septic shock was the most important factor showing a significant risk of mortality.

Duration of the first prone positioning maneuver and its association with 90-day mortality in patients with acute respiratory failure due to COVID-19: A retrospective study of time terciles.

OBJECTIVE: To investigate the association between the duration of the first prone positioning maneuver (PPM) and 90-day mortality in patients with C-ARDS. DESIGN: Retrospective, observational, and analytical study. SETTING: COVID-19 ICU of a tertiary hospital. PATIENTS: Adults over 18 years old, with a confirmed diagnosis of SARS-CoV-2 disease requiring PPM. INTERVENTIONS: Multivariable analysis of 90-day survival. MAIN VARIABLES OF INTEREST: Duration of the first PPM, number of PPM sessions, 90-day mortality. RESULTS: 271 patients undergoing PPM were analyzed: first tertile (n = 111), second tertile (n = 95) and third tertile (n = 65). The results indicated that the median duration of PDP was 14 h (95% CI: 10-16 h) in the first tertile, 19 h (95% CI: 18-20 h) in the second tertile and 22 h (95% CI: 21-24 h) in the third tertile. Comparison of survival curves using the Logrank test did not reach statistical significance (p = 0.11). Cox Regression analysis showed an association between the number of pronation sessions (patients receiving between 2 and 5 sessions (HR = 2.19; 95% CI: 1.07-4.49); and those receiving more than 5 sessions (HR = 6.05; 95% CI: 2.78-13.16) and 90-day mortality. CONCLUSIONS: while the duration of PDP does not appear to significantly influence 90-day mortality, the number of pronation sessions is identified as a significant factor associated with an increased risk of mortality.

Características epidemiológicas, clínicas y funcionales de los pacientes mayores de 75 años ingresados en un hospital terciario durante la primera ola pandémica por SARS-CoV-2 / Epidemiological, clinical, and functional characteristics of patients older than 75 years admitted to a tertiary hospital during the first wave of the SARS-CoV-2 pandemic

Fundamento: Analizar las características epidemiológicas, clínicas y funcionales de los pacientes ingresados en el Hospital Universitario de Navarra por infección por SARS-CoV-2, así como los factores predictores de mortalidad, durante la primera ola de la pandemia provocada por este virus. Metodología: Estudio observacional y retrospectivo de todos los pacientes hospitalizados mayores de 75 años entre marzo y noviembre de 2020. Se ha obtenido información sobre múltiples variables, entre las que cabe destacar los síndromes geriátricos previos y que han aparecido durante la hospitalización, o los antecedentes médicos considerados relevantes en la infección por SARS-CoV-2. Se ha realizado un análisis descriptivo de los datos, comparaciones según diversos factores de interés y análisis multivariable para analizar los factores asociados a la mortalidad. Resultados: Se obtuvieron datos de un total de 426 pacientes cuya edad media fue de 83,2 años (52,6% varones). El 34,7% fallecieron en el hospital y el 4,5% antes de un mes tras el alta hospitalaria. Los factores relacionados con la mortalidad fueron: peor situación funcional basal, enfermedad renal crónica y fiebre o disnea como formas de presentación. Los síntomas típicos más frecuentes fueron: fiebre, disnea, tos, astenia e hiporexia. Hasta el 42,1% presentaron delirium como síntoma de inicio atípico. Se objetivó un deterioro funcional que no se recuperó al mes de seguimiento (índice de Barthel basal 81,12; 70,08 al alta; 75,55 al mes). Conclusiones: La infección por SARS-CoV-2 ha provocado elevadas tasas de mortalidad en las personas mayores. En este grupo etario, es frecuente la forma de presentación atípica de esta enfermedad y el deterioro funcional durante la hospitalización. En el presente estudio se ha identificado un peor estado funcional previo como predictor de mortalidad. Son necesarios más estudios que evalúen el impacto que la enfermedad y la hospitalización tienen en el paciente mayor...(AU)

Background: The objective of the present study is to analyze the epidemiological, clinical and functional characteristics of patients admitted to the University Hospital of Navarra due to SARS-CoV-2 infection, as well as the predictors of mortality, during the first wave of the pandemic caused by this virus. Methodology: An observational, retrospective study was performed, including all hospitalized patients older than 75 years. Information has been obtained on multiple variables, among which it is worth mentioning previous geriatric syndromes or those that have appeared during hospitalization, or past medical history considered relevant in SARS-CoV-2 infection. A descriptive analysis of the data, comparisons according to various factors of interest and multivariate analysis to analyze factors associated with mortality were carried out. Results: Data have been obtained from a total of 426 patients with a mean age of 83.2 years (52.6% men). 34.7% died in hospital and 4.5% within 1 month after hospital discharge. The factors related to mortality were: worse baseline functional status, chronic kidney disease, and fever or dyspnea as forms of presentation. The most frequent typical symptoms were: fever, dyspnea, cough, asthenia and hyporexia. Up to 42.1% presented delirium as a symptom of atypical onset. We observed a functional deterioration that was not recover after a month of follow-up (baseline Barthel index 81.12; 70.08 at discharge; 75.55 after a month). Conclusions: SARS-CoV-2 infection has caused high mortality rates in older adults. In this age group, the atypical presentation of this disease and functional deterioration during hospitalization are frequent. In the present study, a worse previous functional status has been identified as a predictor of mortality. More studies are needed to evaluate the impact that the disease and hospitalization have on the older patient...(AU)

Caracterización de los desenlaces quirúrgicos a corto plazo en gastrectomía por laparoscopia en un centro de alto volumen: 10 años de experiencia / Short-term surgical outcomes of laparoscopic gastrectomy in a high-volume center: 10-year experience

Introducción. El cáncer gástrico en Colombia es la segunda neoplasia más común en hombres y la cuarta en mujeres. En los últimos años se han descrito ampliamente los beneficios del abordaje laparoscópico en el cáncer gástrico frente a sangrado, recuperación postoperatoria y complicaciones, sin afectar los resultados oncológicos. Métodos. Estudio observacional retrospectivo de pacientes llevados a gastrectomía laparoscópica en la Clínica Universitaria Colombia durante un período de diez años, entre 2013 y 2023. Se describieron los resultados perioperatorios en cuanto a estancia hospitalaria, sangrado operatorio, duración del procedimiento, complicaciones, causas de reintervención y mortalidad en los primeros 30 días. Resultados. Se incluyeron 418 pacientes, 58,9 % hombres, con una edad promedio de 60,8 años. Se documentó un tiempo quirúrgico promedio de 228,7 minutos, con un sangrado de 150 ml. La media de ganglios linfáticos resecados fue de 26,1 ± 11,4. La estancia hospitalaria en promedio fue de 4 ± 4 días, y se registraron complicaciones en 104 sujetos, con una tasa promedio de 24 %, de las cuales 29 (27,4 %) obtuvieron una clasificación Clavien-Dindo IIIB. Conclusiones. La gastrectomía por laparoscopia en un centro de alto volumen y con cirujanos experimentados en Colombia, tiene resultados perioperatorios similares a lo reportado en la literatura mundial. Aún se requiere de estudios de mayor fuerza de asociación para establecer recomendaciones sobre el uso rutinario de este abordaje en patología maligna avanzada.

Introduction. Gastric cancer in Colombia is the second most common neoplasm in men and the fourth in women. In recent years, the benefits of the laparoscopic approach in gastric cancer against bleeding, postoperative recovery com and complications have been widely described, without affecting oncological results. Methods. Retrospective observational study of patients undergoing laparoscopic gastrectomy at the Clínica Universitaria Colombia over a period of ten years, between 2013 and 2023. Perioperative results were described in terms of hospital stay, operative bleeding, duration of the procedure, complications, causes of reintervention, and mortality in the first 30 days. Results. 418 patients were included, 58.9% men, with an average age of 60.88 years. An average surgical time of 228.7 minutes was documented, with a blood loss of 150 ml. The mean number of lymph nodes resected was 26.1 ± 11.4. The average hospital stay was 4 ± 4 days, and complications were recorded in 104 subjects, with an average rate of 24%, of which 29 (27.4%) obtained a Clavien-Dindo IIIB classification. Conclusions. Laparoscopic gastrectomy in a high-volume center and with experienced surgeons in Colombia has perioperative results similar to those reported in the world literature. Studies with greater strength of association are still required to establish recommendations on the routine use of this approach in advanced malignant pathology.

Impacto de la edad, las comorbilidades y las complicaciones en pacientes con COVID-19 con síndrome de dificultad respiratoria aguda en la ventilación mecánica invasiva. Estudio multicéntrico observacional / Impact of Age, Comorbidities and Complications in COVID-19 Patients with Acute Respiratory Distress Syndrome on Invasive Mechanical Ventilation. An Observational Multicenter Study

Objetivos: Millones de pacientes con COVID-19 fueron internados en terapia intensiva en el mundo, la mitad desarrollaron síndrome de dificultad respiratoria aguda (SDRA) y recibieron ventilación mecánica invasiva (VMI), con una mortalidad del 50%. Analiza-mos cómo edad, comorbilidades y complicaciones, en pacientes con COVID-19 y SDRA que recibieron VMI, se asociaron con el riesgo de morir durante su hospitalización.Métodos: Estudio de cohorte observacional, retrospectivo y multicéntrico realizado en 5 hospitales (tres privados y dos públicos universitarios) de Argentina y Chile, durante el segundo semestre de 2020.Se incluyeron pacientes >18 años con infección por SARS-CoV-2 confirmada RT-PCR, que desarrollaron SDRA y fueron asistidos con VMI durante >48 horas, durante el se-gundo semestre de 2020. Se analizaron los antecedentes, las comorbilidades más fre-cuentes (obesidad, diabetes e hipertensión), y las complicaciones shock, insuficiencia renal aguda (IRA) y neumonía asociada a la ventilación mecánica (NAV), por un lado, y las alteraciones de parámetros clínicos y de laboratorio registrados.Resultados: El 69% era varón. La incidencia de comorbilidades difirió para los diferentes grupos de edad. La mortalidad aumentó significativamente con la edad (p<0,00001). Las comorbilidades, hipertensión y diabetes, y las complicaciones de IRA y shock se asociaron significativamente con la mortalidad. En el análisis multivariado, sólo la edad mayor de 60 años, la IRA y el shock permanecieron asociados con la mortalidad. Conclusiones: El SDRA en COVID-19 es más común entre los mayores. Solo la edad >60 años, el shock y la IRA se asociaron a la mortalidad en el análisis multivariado.

Objectives: Millions of patients with COVID-19 were admitted to intensive care world-wide, half developed acute respiratory distress syndrome (ARDS) and received invasive mechanical ventilation (IMV), with a mortality of 50%. We analyzed how age, comor-bidities and complications in patients with COVID-19 and ARDS who received IMV were associated with the risk of dying during their hospitalization.Methods: Observational, retrospective and multicenter cohort study carried out in 5 hospitals (three private and two public university hospitals) in Argentina and Chile, during the second half of 2020.Patients >18 years of age with SARS-CoV-2 infection confirmed by RT-PCR, who devel-oped ARDS and were assisted with IMV for >48 hours, during the second half of 2020, were included. History, the most frequent comorbidities (obesity, diabetes and hyper-tension) and the complications of shock, acute renal failure (AKI) and pneumonia as-sociated with mechanical ventilation (VAP), on the one hand, and the alterations of re-corded clinical and laboratory parameters, were analyzed.Results: 69% were men. The incidence of comorbidities differed for different age groups. Mortality increased significantly with age (p<0.00001). Comorbidities, hyper-tension and diabetes, and complications of ARF and shock were significantly associat-ed with mortality. In the multivariate analysis, only age over 60 years, ARF and shock remained associated with mortality.Conclusions: ARDS in COVID-19 is more common among the elderly. Only age >60 years, shock and ARF were associated with mortality in the multivariate analysis

Method: An observational, longitudinal, quantitative and descriptive study, classified as an ecological study in the field of epidemiology. This study focuses on measuring excess mortality during the years 2020, 2021 and 2022, using the average number of deaths that occurred in the period from 2015 to 2019 as the baseline. Results: From January 2020 to October 2022, Ecuador accumulated a total excess of deaths of 98,915. In 2020, the excess mortality was higher at 46,374, with the highest value occurring in April at 15,484. In 2021, the excess deaths amounted to 35,859, with April having the highest excess of 7,330. In 2022, the excess mortality was 16,682, with January recording the highest excess at 4,204. Conclusion: Evidence of underreporting of deaths, as well as temporal and geographi-cal variations in excess mortality, was observed. The province with the highest number of deaths and excess mortality was Guayas, followed by Pichincha. The results provide an analysis of the situation during the health emergency, emphasizing the importance of evaluating the healthcare system's capacity to respond during times of crisis and the imperative need to implement corrective measures for the future.

Epidemiology and outcomes of pediatric cardiac arrest in a cardiovascular unit at a public hospital in Argentina.

BACKGROUND: Children with congenital heart disease present a higher frequency of cardiorespiratory arrest (CRA) than the general pediatric population. The epidemiology of CRA is not exactly known in our setting, nor are the mortality risk or the neurological evolution factors. OBJECTIVE: To describe the epidemiology and outcomes associated with pediatric cardiopulmonary resuscitation in a cardiovascular recovery unit. The primary endpoint was the survival to discharge and the secondary endpoints were the return to spontaneous circulation, the survival at 24 hours and the remote neurological condition. METHODS: Descriptive, prospective, longitudinal cohort study in children under 18 years of age who required cardiopulmonary resuscitation between 2016 and 2019. Demographic variables, characteristics of cardiopulmonary arrest, resuscitation and outcome were analyzed. An uni- and multivariate analysis was performed comparing survivors and deceased. RESULTS: Out of 1,842 hospitalized patients, 4.1% presented CRA. Fifty patients with complete records were analyzed. Seventy-eight percent (39) returned to spontaneous circulation with a high survival rate of 46%. Resuscitation > 6 min and the use of vasoactive drugs were predictors of mortality; 16/23 patients were followed up, 10 of them with normal development for age at 6 months, six had pervasive developmental disorder. CONCLUSIONS: 4.1% of patients presented CRA, with a rate of 3.4 CRA per 1,000 patient-days. Survival at hospital discharge (n = 50) was 46%. Resuscitation > 6 min and the use of vasoactive drugs were independent predictors of mortality. At six months, 63% had normal neurological development for age.

ANTECEDENTES: Los niños con cardiopatías congénitas experimentan paro cardiorrespiratorio (PCR) con mayor frecuencia que la población pediátrica general. Se desconoce la epidemiología exacta del PCR en nuestro medio, al igual que el riesgo de mortalidad y los factores que influyen en la evolución neurológica. OBJETIVO: Describir la epidemiología y los resultados asociados con la reanimación cardiopulmonar pediátrica en una unidad de recuperación cardiovascular. El criterio de valoración primario fue la supervivencia al momento del alta hospitalaria; los secundarios fueron el retorno de la circulación espontánea, la supervivencia a las 24 horas y la condición neurológica en el largo plazo. MÉTODO: Estudio de cohorte longitudinal, descriptivo, prospectivo, en menores de 18 años que requirieron reanimación cardiopulmonar entre 2016 y 2019. Se analizaron las variables demográficas y las características del paro cardiorrespiratorio y de la reanimación, así como su resultado. Se realizaron análisis de una y múltiples variables para comparar a los pacientes sobrevivientes con los fallecidos. RESULTADOS: De los 1,842 pacientes internados, el 4.1% experimentó PCR. Se analizaron 50 pacientes con expedientes completos. Se logró el retorno de la circulación espontánea en el 78% (39), con una supervivencia alta del 46%. La reanimación > 6 min y el uso de fármacos vasoactivos fueron factores predictivos de mortalidad; se realizó el seguimiento de 16/23 pacientes, 10 de ellos con desarrollo normal para la edad luego de seis meses, seis tenían trastorno generalizado del desarrollo. CONCLUSIONES: El 4.1% de los pacientes presentó un PCR, con una tasa de 3.4 PCR por 1,000 días-paciente. La supervivencia al egreso hospitalario (n = 50) fue del 46%. La reanimación > 6 min y la utilización de fármacos vasoactivos fueron factores predictivos independientes de mortalidad. Luego de seis meses, el 63% tenía desarrollo neurológico normal para la edad.
