Introducción. El objetivo de este estudio fue comparar los desenlaces a corto plazo de la gastrectomía laparoscópica en adultos vs. adultos mayores con cáncer gástrico localmente avanzado en una cohorte de un país occidental. Métodos. Estudio de cohorte prospectivo en pacientes sometidos a gastrectomía laparoscópica por cáncer gástrico localmente avanzado, en el Hospital Universitario Erasmo Meoz, de Cúcuta, Colombia, entre noviembre de 2014 y diciembre de 2018. Se realizó análisis descriptivo, de comparación de grupos y bivariado. Resultados. De un total de 116 pacientes, 51 pacientes (44 %) tenían 65 años o más y 63 pacientes (54 %) eran hombres. No se encontró diferencia estadísticamente significativa al comparar los pacientes menores de 65 años con los de 65 años o más. La mediana del tiempo operatorio fue de 240 minutos en ambos grupos (p>0,05), la mediana de los márgenes de resección macroscópica fue 6 cm vs. 5 cm (p>0,05), la mediana de los ganglios linfáticos disecados fue 25 vs. 19 (p>0,05), la mediana de ganglios linfáticos positivos fue 4 vs. 3 (p>0,05), la mediana de estancia fue de 7 días en ambos grupos (p>0,05). La tasa general de complicaciones posoperatorias no difirió significativamente entre adultos (7%) y adultos mayores (11 %) (p>0,05) y no se observaron diferencias significativas en las tasas de complicaciones menores (Clavien-Dindo grado II; 3-5 % vs. 6-12 %; p>0,05) y graves (Clavien-Dindo ≥ IIIa; 3-5 % vs. 4-8 %; p>0,05). Conclusiones. No se encontraron diferencias estadísticamente significativas en los resultados a corto plazo entre los pacientes adultos y adultos mayores con cáncer gástrico localmente avanzado tratados con gastrectomía laparoscópica. Esta técnica es segura en ancianos.
Introduction. The objective of this study was to compare the short-term outcomes of laparoscopic gastrectomy in adults vs. older patients with locally advanced gastric cancer from a Western country cohort. Methods. Prospective cohort study in patients undergoing laparoscopic gastrectomy for locally advanced gastric cancer at the Hospital Universitario Erasmo Meoz, de Cúcuta, Colombia, between November 2014 and December 2018. Descriptive, group comparison and bivariate analysis was performed. Results. Of a total of 116 patients, 51 patients (44%) were 65 years or older and 63 patients (54%) were men. No statistically significant difference was found when comparing patients under 65 years of age with those 65 years of age or older. The median operating time was 240 minutes in both groups (p>0.05), the median macroscopic resection margins were 6 cm vs. 5 cm (p>0.05), the median number of lymph nodes dissected was 25 vs. 19 (p>0.05), the median number of positive lymph nodes was 4 vs. 3 (p>0.05), the median stay was 7 days in both groups (p>0.05). The overall rate of postoperative complications did not differ significantly between adults (7%) and older adults (11%) (p>0.05) and no significant differences were observed in the rates of minor (Clavien-Dindo grade II; 3-5% vs. 6-12%; p>0.05) and severe complications (Clavien-Dindo ≥ IIIa; 3-5% vs. 4-8%; p>0.05). Conclusions. No statistically differences were found in short-term outcomes between adult and older patients with locally advanced gastric cancer treated with laparoscopic gastrectomy. This technique is safe in the elderly.

Background: The Americas region has the lowest (North America) and the second highest (Latin America and Caribbean) cervical cancer (CC) mortality worldwide. The lack of reliable data on screening coverage in the region hinders proper monitoring of the World Health Organization (WHO) CC elimination initiative. Methods: For this synthetic analysis, we searched data on CC screening coverage from official sources and national health surveys, supplemented with a formal WHO country consultation. Context data were obtained from official sources (income, health expenditure, inequality-adjusted human development index -IHDI-, universal health coverage, CC incidence/mortality). Country age-specific coverages for 2019 by screening interval were computed. Missing data were imputed through a multi-step algorithm. Beta-regression and Poisson-regression models were used to analyse associations between context variables, screening coverage, and CC mortality. Findings: We included data from 37 countries in the Americas. Data on coverage of HPV testing was scarce, and for many countries only Pap-smear coverage data was available. Overall, 78%, 34%, 60%, and 67% of women aged 25-65 years have been screened ever in their lifetime, and in the previous year, 3 years, and 5 years, respectively. By sub-region, 3-year coverage ranges from 48% (South America) to 72% (North America). Twenty-four countries showed screening coverage below 70%. Income and health system type were associated with screening coverage, but coverage was not associated with CC mortality. Interpretation: In the Americas region 35.1% and 56.8% of countries report 3-year and 5-year coverage over 70%, respectively. Inequalities remain a major challenge for screening programs in the region. The elimination campaign should reinforce the transition to HPV testing and strengthen surveillance systems. Funding: Instituto de Salud Carlos III, European Regional Development Fund, Secretariat for Universities and Research of the Department of Business and Knowledge of the Government of Catalonia, and Horizon 2020.
RESUMO
OBJECTIVES: Cervical cancer elimination requires high-performance screening tests and high treatment rates, and thus high screening program performance is essential; however, Latin America lacks organized screening and quality assurance (QA) guidelines. We aimed to develop a core set of QA indicators suitable to the region. METHODS: We reviewed QA guidelines from countries/regions with highly organized screening programs and selected 49 indicators for screening intensity, test performance, follow-up, screening outcomes and system capacity. A regional expert consensus using the Delphi method in two rounds was implemented to identify basic indicators actionable within the regional context. The panel was integrated by recognized Latin American scientists and public health experts. They voted for the indicators blinded to each other based on feasibility and relevance. The correlation between both attributes was analyzed. RESULTS: In the first round 33 indicators reached consensus for feasibility but only 9 for relevance, without full coincidence. In the second round 9 indicators met the criteria for both (2 screening intensity, 1 test performance, 2 follow-up, 3 outcomes, 1 system capacity). A significant positive correlation was observed for test performance and outcomes indicators between the two attributes assessed (p < 0.05). CONCLUSIONS: Cervical cancer control requires realistic goals supported by proper programs and QA systems. We identified a set of indicators suitable to improve cervical cancer screening performance in Latin America. The assessment by an expert panel with a joint vision from science and public health practice represents a significant progress towards real and feasible QA guidelines for countries in the region.

OBJECTIVE: To describe current cervical cancer screening program guidelines in Latin America. MATERIALS AND METHODS: We searched official recommendations for the general population and women living with HIV (WLHIV) by reviewing official sources from 19 countries; these data were supplemented with a consultation carried out by the WHO with the Ministries of Health. RESULTS: Screening policies vary significantly in regard to target populations, primary tests, and screening intervals. Sixteen countries have recently updated their recommendations; however, cytology remains the primary screening test for most countries. Eleven countries have introduced HPV tests, and eight countries have implemented screen-and-treat algorithms; only three countries have developed evidence-based guidelines. All countries but Costa Rica have specific recommendations for WLHIV. CONCLUSIONS: Although most countries have updated their screening policies, only a few are properly alig-ned with the WHO elimination strategy. Recommendations for WLHIV require better integration with cervical cancer screening programs.

INTRODUCTION: Chronic diseases are a public health problem, and 80% of them are related to modifiable risk factors such as unhealthy diet, physical inactivity, smoking, and risky alcohol consumption. Although the intervention in smoking and hazardous alcohol drinking has proven to be effective in Primary Care, it is unknown whether it works in the same way in the hospital setting. OBJECTIVE: To evaluate the effectiveness of brief counselling in order to modify the stage of change in smokers and at-risk drinkers treated in a high complexity hospital. METHODS: A Randomised controlled trial to be conducted, in which an evaluation is made of four brief counselling strategies for smoking cessation and risky alcohol consumption compared to usual care, selected according to the patient's stage of change. The primary result will be the proportion of patients in each of the groups (intervention and control) with identified progress in the stage of change. The reduction of consumption will be also be analysed. Protocol registered at ClinicalTrials.gov (NCT03521622). RESULTS: The results will be published in scientific journals, and its application aims to generate behavioural intervention protocols for modifiable risk factors in high complexity hospitals. The trial was presented and approved by the Ethics and Research Committee of the Pontificia Universidad Javeriana and Hospital Universitario de San Ignacio, Bogota, Colombia (Approval 01/2018).

Resumen Introducción: Las enfermedades crónicas son un problema de salud pública; el 80% de ellas se relacionan con factores de riesgo modificables, como una dieta poco saludable, la inactividad física, el tabaquismo y el consumo riesgoso de alcohol. La intervención en el tabaquismo y el consumo riesgoso de alcohol se ha demostrado efectiva en el cuidado primario, pero se desconoce si funciona de la misma manera en el contexto hospitalario. Objetivo: Evaluar la efectividad de la consejería breve para modificar el estadio de cambio en pacientes fumadores y bebedores en riesgo atendidos en un hospital de alta complejidad. Métodos: Experimento clínico aleatorizado, que evalúa la efectividad de 4 modalidades de consejería breve para la cesación de tabaquismo y el consumo riesgoso de alcohol en comparación con el cuidado habitual, seleccionadas según el estadio de cambio del sujeto. El resultado primario es la proporción de pacientes en cada uno de los grupos (intervención y control) en los cuales se identifica el avance en el estadio de cambio; además se analizará la reducción de consumos. Protocolo registrado en ClinicalTrials.gov (NCT03521622). Resultados: Los resultados se publicarán en revistas de literatura científica y su aplicación pretende generar protocolos de intervenciones conductuales en factores de riesgo modificables en hospitales de alta complejidad. El experimento fue presentado y aprobado por el Comité de Ética e Investigación de la Pontificia Universidad Javeriana y el Hospital Universitario de San Ignacio (aprobación 01/2018).

RESUMO
On June 2, 2021, the Colombian Ministry of Health and Social Protection, through Resolution No. 777, laid down the requirements to resume all restricted economic and social activities. Similarly, said Resolution established the Municipal Epidemiological Resilience Index (IREM by its acronym in Spanish) as a tool to support decision-making regarding this economic reactivation amid the third epidemic peak of COVID-19 in the country. The purpose of this article is to perform a critical analysis of the technical aspects of the IREM and to explore the feasibility of its implementation as a support for the resumption of economic and social activities as proposed in the Resolution. The present critical analysis emphasizes on the lack of a clear definition of epidemiological resilience that is consistent with the scientific literature. Furthermore, the face and content validity of the index, as well as the construct validity of the index and of its dimensions, are called into question and, therefore, the feasibility of using it to determine said resumption.
El 2 de junio de 2021, el Ministerio de Salud y Protección Social de Colombia expidió la Resolución 777, mediante la cual se determinan las condiciones para el reinicio de todas las actividades económicas y sociales restringidas. Asimismo, en esta resolución se define el Índice de resiliencia epidemiológica municipal (IREM) como la herramienta para apoyar la toma de decisiones relacionadas con esta reactivación económica en medio del tercer pico epidémico de la COVID-19 en el país. El objetivo de este artículo es hacer un análisis crítico de los aspectos técnicos del IREM y explorar la conveniencia de su implementación como soporte del reinicio de las actividades económicas y sociales propuesto en la resolución. Dentro de este análisis crítico se destaca la falta de una clara definición de resiliencia epidemiológica que se ajuste a la literatura científica. Además, se cuestiona tanto la validez de apariencia, contenido y constructo del índice global, como la validez del constructo de sus dimensiones y, por tanto, la pertinencia de usarlo como herramienta para definir dicho reinicio.
RESUMO
Resumen Objetivo Analizar y sintetizar la evidencia sobre el efecto del consumo habitual de café en la aparición de enfermedad cardiovascular. Métodos Se realizó una evaluación crítica de la literatura basada en metaanálisis y revisiones sistemáticas publicadas en Medline, EMBASE, Cochrane Database of Systematic Reviews y LILACS (enero 1966 a junio 2018). La búsqueda, selección y extracción de información fue llevada a cabo por una pareja de investigadores. La calidad de los manuscritos fue evaluada con AMSTAR. Resultados Se analizaron cuatro revisiones sistemáticas que consideraron como desenlaces enfermedad coronaria, riesgo cardiovascular e infarto del miocardio; para el primer y segundo desenlace se encontró una reducción del riesgo con consumo de 3-4 tazas/día (RR=0,90; IC95% 0,84-0,9; p de heterogeneidad=0,02 y RR=0,85; IC95% 0,80-0,90; p de heterogeneidad=0,09); para 1-2 tazas/día (RR=0,89; IC95% 0,85-0,94; p de heterogeneidad=0,83 y RR=0,89; IC95% 0,84-0,94; p de heterogeneidad=0,09) respectivamente. Para infarto agudo de miocardio se reportó un aumento del riesgo en hombres con consumo de 3-4 tazas/día (OR=1,75; IC95% 1,44-2,14; p de heterogeneidad=0,005) y de ≥ 4 tazas/día (OR=2,01; IC95% 1,7-2,36; p de heterogeneidad<0,001). Conclusiones Los consumos leves y moderados de café tienen un efecto neutro o de reducción del riesgo cardiovascular y de enfermedad coronaria; en contraste, el riesgo de infarto agudo de miocardio se incrementa con consumos mayores o iguales a 3 tazas/día en hombres. Se recomienda el consumo de hasta 3 tazas de café día y se desaconsejan consumos mayores, especialmente en hombres.
Abstract Objective To analyse and summarise the evidence on the effect of regular coffee drinking on the appearance of cardiovascular disease. Methods A critical review of the literature was carried out based on a meta-analysis and systematic reviews published in MedLine, EMBASE, Cochrane Database of Systematic Reviews, and LILACS (January 1966 to June 2018). The search, selection, and extraction of the information were performed by two investigators. The quality of the manuscripts was evaluated using AMSTAR. Results An analysis was made of 4 systematic reviews that considered coronary disease, cardiovascular risk, and myocardial infarction as outcomes. For the first and second outcomes, a reduction in risk was found with consuming 3-4 cups/day (RR=0.90; 95%CI; 0.84-0.9; P=.02, and RR=0.85; IC95% CI; 0.80-0.90; P=.09); for 1-2 cups/day (RR=0.89; 95%CI; 0.85-0.94; P=.83, and RR=0.89; 95%CI; 0.84-0.94; P=.09), respectively. As regards myocardial infarction, an increase in risk was reported with consuming 3-4 cups/day (OR=1.75; 95%CI; 1.44-2.14; P=.005) and ≥ 4 cups/day (OR=2.01; IC95%CI; 1.7-2.36; P<.001). Conclusion Mild and moderate consumption of coffee has a neutral effect or a reduction in cardiovascular risk and coronary disease. On the other hand, the risk of myocardial is increased with drinking more or equal to 3 cups/day in men. The drinking of up to 3 cups of coffee/day is recommended, and it is not advised to drink more, especially in men.

OBJECTIVE: Poor sleep quality is a common problem in the general population, frequently associated with personal habits and comorbid conditions. University students may be a vulnerable population because of their daily routine, habits and sleep hygiene behavior. There are few related studies on this subject in Colombian undergraduates. The aim of this study is to characterize sleep quality in Colombian university undergraduates and examine possible associated factors. METHODS: Cross-sectional study was performed with self-administered questionnaires including demographic data, lifestyle habits, sleep hygiene habits and sleep quality measured by the Pittsburgh Sleep Quality Index (PSQI). The study group included 414 students from different schools enrolled at the Pontificia Universidad Javeriana in Bogotá, Colombia. RESULTS: Prevalence of poor sleep quality according to PSQI was 58.9%. Multivariate analysis showed an association of poor sleep quality with smoking (OR = 3.17 [1.51-6.66]) and eating in bed (OR = 2.13 [1.31-3.47]), with probable protective factors in sleeping at the same time (OR = 0.37 [0.25-0.59]) and having breakfast 5 or more days of the week (OR = 0.53 [0.31-0.91]). DISCUSSION: Poor sleep quality is frequent among undergraduates, regardless of their area of study. The identification of possible related factors may help to design targeted preventive measures, as it is promoting healthy lifestyle habits, adequate sleep hygiene practices and avoiding tobacco use.
RESUMO
El objetivo de este estudio fue establecer la relación entre consumo habitual de café y la mortalidad general y cardiovascular. En una búsqueda sistemática en Medline, EMBASE, LILACS y Cochrane se seleccionaron y analizaron revisiones sistemáticas y meta-análisis por una pareja de investigadores. De 181 referencias, 74 fueron seleccionadas por título y resumen; luego de eliminar duplicados y según el puntaje de calidad obtenido por AMSTAR, se consideraron 5 artículos para extracción y análisis. El consumo moderado de café (3 o 4 tazas) disminuye la mortalidad general, tanto comparado con el no consumo (RR= 0,83; IC95%: 0,79-0,88; I2= 83% para 3 tazas, y RR=0,84 IC95%: 0,82-0,87; I2= 58% para 4), como con un consumo mínimo (RR= 0,88; IC95%: 0,84-0,93; I2= 68,7% para 4 tazas, y RR= 0,87; IC95%: 0,83-0,91; I2= 59,8% para consumo entre 3 y 4 tazas). La mortalidad cardiovascular se reduce si se compara con el no consumo, para 4 tazas (RR= 0,80; IC95%: 0,74-0,86; I2= 58%) y (RR= 0,83; IC95%: 0,75-0,92, I2 = 92%) y para 3 tazas (RR= 0,81; IC95%: 0,72-0,90; I2= 92%) y RR (0,79; IC95% 0.74-0.84; I2= 58%). Como conclusión, el consumo habitual de 3 y 4 tazas de café reduce la mortalidad general y cardiovascular.
The objective of this study was to establish the relationship between habitual coffee consumption and all-cause and cardiovascular mortality. A systematic review was conducted using Medline, EMBASE, LILACS and Cochrane databases. Systematic reviews and meta-analysis were selected and analyzed. From 181 systematic reviews, 74 were selected by title and summary; after eliminating duplicates. According to the quality score of the AMSTAR tool, five articles were selected for information extraction and analysis. Moderate coffee consumption (3 or 4 cups) decreased overall mortality, compared to non-consumption (RR= 0.83, 95% CI: 0.79-0.88; I2= 83% for 3 cups, and RR= 0.84, 95% CI: 0.82-0.87; I2= 58% for 4 cups) and minimum consumption (RR= 0.88, 95% CI: 0.84-0.93; I2= 68.7% for 4 cups, and RR= 0.87, 95% CI: 0.83-0.91; I2= 59.8% between 3 and 4 cups). Cardiovascular mortality was reduced when compared to non-consumption, for 4 cups (RR= 0.80, 95% CI: 0.74-0.86; I2= 58%) and (RR= 0.83, 95% CI: 0.75-0.92; I2= 92%), and for 3 cups (RR= 0.81, 95 CI: 0.72-0.90; I2= 92%; RR= 0.79, 95% CI: 0.74-0.84; I2= 58%). In conclusion, habitual coffee consumption between 3 and 4 cups reduces the risk of all-cause and cardiovascular mortality.

RESUMO
Abstract Introduction: Methicillin-resistant Staphylococcus aureus is a frequent pathogen at critical care services. Its presence leads to increased hospital stays and mortality risk in patients with bacteremia. However, the etiology of this resistance marker has not been fully studied. Objective: To identify risk factors associated with the emergence of methicillin-resistant S. aureus bacteremia in critically ill patients treated at intensive care units in Bogotá, Colombia. Materials and methods: We conducted a retrospective paired case-control study, nested in a cohort of patients diagnosed with S. aureus bacteremia and treated at intensive care units between 2006 and 2008 in Bogotá. Cases were patients with positive blood culture to methicillin resistance, matched in a 1:1 ratio with methicillin-sensitive controls isolated from the same institution and hospitalization year. We used conditional logistic regression to analyze the risk factors associated with the presence of resistance, with emphasis on prior antibiotic therapy. Results: We included 372 patients with S. aureus bacteremia. Factors such as the use of pre-hospital devices: vascular (OR=1.986, 95% CI 1.038 to 3.801) and urinary (OR=2.559, 95% CI: 1.170 to 5.596), along with the number of previously used antibiotics, were associated with the emergence of resistance. The number of antibiotics used previously was determined to have a gradient effect, particularly carbapenems. Conclusions: The rational use of antibiotics and surveillance of exposure to surgical procedures or use of invasive devices are interventions that could diminish the emergence of methicillin-resistant S. aureus bacteremia causes.
Resumen Introducción. Staphylococcus aureus resistente a la meticilina es uno de los agentes patógenos más frecuentes en las unidades de cuidados intensivos. Su presencia prolonga las hospitalizaciones y aumenta el riesgo de mortalidad en los pacientes con bacteriemia. Sin embargo, la etiología de este marcador de resistencia no ha sido completamente estudiada. Objetivo. Determinar los factores asociados con la aparición de S. aureus resistente a la meticilina causante de bacteriemia en pacientes atendidos en unidades de cuidados intensivos en Bogotá. Materiales y métodos. Se hizo un estudio retrospectivo de casos y controles emparejados, anidado en una cohorte de pacientes con diagnóstico de bacteriemia por S. aureus atendidos en unidades de cuidados intensivos de Bogotá entre 2006 y 2008. Los casos fueron pacientes con hemocultivo positivo para resistencia a la meticilina, emparejados 1 a 1 con controles con hemocultivos sensibles a la meticilina de la misma institución y año de hospitalización. Se analizaron mediante regresión logística condicional los factores de riesgo asociados con la presencia de resistencia, con énfasis en el tratamiento previo con antibióticos. Resultados. Se incluyeron 372 pacientes con bacteriemia por S. aureus. Factores como el uso de dispositivos previos a la hospitalización: vasculares (Odds ratio, OR=1,986; IC95% 1,038-3,801) y urinarios (OR=2,559; IC95% 1,170-5,596), así como el número de antibióticos administrado previamente, se asociaron con la aparición de resistencia. Se registró un efecto de gradiente con el número de antibióticos usados previamente, especialmente carbapenémicos. Conclusiones. El uso racional de antibióticos y la vigilancia de la exposición a procedimientos quirúrgicos o al uso de dispositivos invasivos, son intervenciones que podrían disminuir la aparición de S. aureus resistente a meticilina causante de bacteriemia.

Este artículo resume las recomendaciones de una guía para el diagnóstico y tratamiento de las infecciones bacterianas y micóticas en pacientes oncológicos mayores de 15 años con neutropenia febril posquimioterapia de alto riesgo. Métodos: Guía de práctica clínica basada en la evidencia. Se realizó la definición de preguntas clínicas, la búsqueda sistemática de literatura, la evaluación crítica de la evidencia y la formulación de recomendaciones. Se desarrolló una evaluación económica sobre la eficiencia de dos esquemas diferentes de tratamiento antimicótico. Resultados: El presente documento incluye recomendaciones para el diagnóstico de infecciones bacterianas y micóticas en paciente con neutropenia, el uso de profilaxis antibiótica y antimicótica, el tratamiento antibiótico empírico, y el tratamiento antimicótico empírico y anticipado en pacientes mayores de 15 años, acorde con la microbiología del contexto colombiano. Conclusiones: La implementación oportuna de las recomendaciones de la guía acorde con el contexto clínico de cada paciente debe contribuir a mejorar la supervivencia y morbilidad infecciosa de los pacientes con neutropenia febril derivada de la quimioterapia.
Objective: Current cancer treatment is intended to improve survival by implementing intensified chemotherapy strategies, which increases the likelihood of neutropenia and favors the development of bacterial and invasive fungal infections. This paper summarizes clinical practice guideline recommendations for the diagnosis and treatment of bacterial and fungal infections in patients older than 15 years with febrile neutropenia after high risk chemotherapy. Methods: Evidence-based clinical practice guideline. A set of clinical questions was defined, a literature search performed, critical appraisal of the evidence, as the development of recommendations. An economic assessment was carried out on two alternative schemes for fungal therapy. Results: This article includes recommendations for the diagnosis of bacterial and fungal infections in neutropenic patients, prophylaxis for bacterial and fungal infections, empiric antimicrobial treatment, empiric and anticipated antifungal therapy in patients over 15 years, according to the microbiology setting in Colombia. Conclusions: Timely implementation of these recommendations according to each clinical context, should contribute to improve survival and reduce infection-derived morbidity in patients with chemotherapy-induced febrile neutropenia.

Introducción. La bacteriemia es una de las infecciones hospitalarias de mayor mortalidad, especialmente en las unidades de cuidados intensivos, donde es más frecuente. Pseudomonas aeruginosa es uno de los causantes de bacteriemia más agresivos. Objetivo. Evaluar la asociación entre el tratamiento antibiótico inicial y la mortalidad hospitalaria en estos pacientes. Materiales y métodos. Se trata de un estudio de cohorte retrospectivo multicéntrico realizado entre 2005 y 2008. Se consideró tratamiento adecuado aquel iniciado en las primeras 48 horas del diagnóstico que incluyera, al menos, una dosis de antibiótico intravenoso al que P. aeruginosa fuera sensible y hubiera sido suministrado en la dosis y frecuencia recomendadas. El desenlace principal fue la mortalidad hospitalaria en un lapso de 30 días. Se hizo pareo según grado de exposición usando índices de propensión y, posteriormente, análisis paramétrico de supervivencia. Resultados. Se incluyeron 164 pacientes. La mediana de edad y la clasificación del APACHE II ( Acute Physiology and Chronic Health Evaluation II ) fue de 56 y 13, respectivamente. Se identificó la fuente de la bacteriemia en 68,3 % de los casos, y la más frecuente fue el tracto respiratorio; 44 % de los pacientes recibió tratamiento inadecuado, y la resistencia bacteriana fue la principal variable asociada. La proporción de incidencia de sepsis grave, choque séptico, falla orgánica múltiple y muerte en el lapso de 30 días fue de 67,7, 50, 41,5 y 43,9 %, respectivamente. El tratamiento adecuado se asoció a una prolongación del tiempo hasta el evento (razón de tiempo ajustada, 2,95, IC 95%, 1,63 a 5,33). Conclusión. El tratamiento antibiótico inicial adecuado es un factor protector contra la mortalidad hospitalaria en pacientes con bacteriemia por P. aeruginosa .
Introduction: Among hospital-acquired infections, bacteremia is one of the leading causes of mortality worldwide, especially among intensive care unit patients, where it is more frequent. Pseudomonas aeruginosa is one of the most aggressive agents causing bacteremia. Objective: To evaluate the association between initial antimicrobial therapy and hospital mortality in these patients. Materials and methods: A multicenter and retrospective cohort study was conducted between 2005 and 2008. Antimicrobial therapy was considered adequate if it included at least one intravenous antibiotic to which the P. aeruginosa isolate was susceptible in vitro, was administered at the recommended dose and frequency for bacteremia, and initiated within the first 48 hours from diagnosis. The main outcome was 30-day hospital mortality. Patients were paired according to exposure level using propensity score matching, and then a parametric survival model was fitted. Results: One hundred and sixty four patients were included. Median age and the APACHE II score were 56 and 13, respectively. The source of bacteremia was identified in 68.3 % of cases, the respiratory tract being the most frequent. Forty-four percent of patients received inadequate therapy, with bacterial resistance as the main associated variable. The incidence of severe sepsis, septic shock, multiple organ failure and death within the first 30 days was 67.7, 50, 41.5 and 43.9%, respectively. Adequate therapy was associated with a longer time to the event (adjusted time ratio, 2.95, 95% CI, 1.63 to 5.33). Conclusion: Adequate initial antimicrobial therapy is a protective factor against hospital mortality in patients with P. aeruginosa bacteremia.

OBJECTIVE: The aim of this study was to describe the most frequently found bacterial microorganisms in bloodstream isolates taken from patients in intensive care units in Colombia and their resistance profiles. METHODS: This was a multicentre descriptive observational study that was carried out between January 2001 and June 2008 with laboratory data from 33 participating hospitals in a surveillance network. RESULTS: The most frequently found microorganisms were coagulase-negative Staphylococci 39.6%, Staphylococcus aureus 12.3%, Klebsiella pneumoniae 8.2%, Escherichia coli 5.7%, Acinetobacter baumannii, 4.0% and Pseudomonas aeruginosa 3.8%. Coagulase-negative Staphylococci registered greater than 70% oxacillin resistance rate. S. aureus presented a change in its multiresistance profile during the years of follow-up. There was a trend towards a lower resistance rate among E. coli and K. pneumoniae isolates during the study period while A. baumannii carbapenem resistance rate exceeded 50%. DISCUSSION: There has been a change in the frequency of species being isolated with a higher frequency of enterobacteriaceae compared to Gram-positive microorganisms, in general with a high resistance rate.

Introducción. El tabaquismo es el principal factor de riesgo para enfermedades crónicas que constituyen la mayor carga en Colombia. Objetivos. Generar recomendaciones de práctica clínica sobre eficacia y seguridad del tratamiento para la cesación de la adicción al tabaco en adultos colombianos. Materiales y métodos. Se hizo una adaptación basada en la metodología ADAPTE. Se buscaron guías de práctica clínica en Medline, EMBASE, CINAHL, LILACS y Cochrane. Se evaluó la cesación a seis meses para consejería breve e intensiva, terapia de reemplazo nicotínico, bupropión, vareniclina, clonidina, nortriptilina, acupuntura, hipnosis, homeopatía y la combinación de tratamientos. Se utilizó el German Instrument for Methodological Guideline Appraisal (DELBI) para evaluar las guías de prácticalínica. Se seleccionaron las guías con puntaje mayor de 60 % en rigor metodológico y aplicabilidad en Colombia. Las preguntas sin evidencia fuerte se llevaron a consenso. Resultados. Se encontraron 925 referencias, se preseleccionaron 17 guías de práctica clínica y se escogieron 5 para adaptación. La consejería breve e intensiva, la terapia de reemplazo nicotínico, el bupropión, la nortriptilina y la vareniclina son eficaces en la cesación de tabaquismo (incrementó 5,1 % a 22,7 %). Los tratamientos alternativos no tienen eficacia demostrada en la cesación. El uso simultáneo de diferentes formas de terapia de reemplazo nicotínico es la única combinación con eficacia demostrada (OR 1,9; 95%: 1,3-2,7). Conclusiones. Existen diversas alternativas con eficacia demostrada para dejar de fumar. Los incrementos en las tasas de cesación son variables y la duración del efecto necesita mayor seguimiento. Para aplicar la consejería breve e intensiva en Colombia, se deben usar formatos estándar. Se requieren evaluaciones económicas para valorar el impacto y seleccionar las mejores intervenciones en el contexto colombiano.
Introduction: Chronic diseases represent the greatest burden of disease in Colombia for which smoking is the major risk factor. Objectives: To provide clinical practice recommendations based upon efficacy and safety of smoking cessation therapies for Colombian adults. Materials and methods: An adaptation of clinical practice guidelines (CPG) based on the ADAPT methodology was performed. We searched CPG on Medline, EMBASE, CINAHL, LILACS, and Cochrane databases. Six months cessation rates were appraised for brief and intensive counseling, nicotine replacement therapy (NRT), bupropion, varenicline, clonidine, nortriptyline, acupuncture, hypnosis, homeopathy, and combined treatments. CPG were evaluated with DELBI and selected when having a score above 60% for methodological rigor of development and applicability to the Colombian health system. Formal consensus was performed for questions without strong evidence. Results: 925 references were found, 17 CPG were pre-selected and 5 selected for adaptation. Brief and intensive counseling, NRT, bupropion, nortriptyline, and varenicline are effective for smoking cessation (cessation rates augment 5.1%-22.7%). Alternative therapies have not demonstrated cessation efficacy. Concomitant use of different NRT is the only combination with demonstrated efficacy (OR 1.9, 95%CI 1.3-2.7). Conclusions: Several alternatives for giving up tobacco smoking have confirmed efficacy. The absolute difference in cessation rates is variable among therapies and duration of effect requires further research. Brief and intensive counseling necessitate standardized formats for their implementation in Colombia. Economic evaluations are required to assess costs and benefits and to select the most suitable interventions for Colombia.

OBJECTIVE: A systematic review on efficacy and safety of smoking cessation counseling was developed. MATERIALS AND METHODS: The ADAPTE methodology was used with a search of Clinical Practice Guidelines (CPG) in Medline, EMBASE, CINAHL, LILACS, and Cochrane. DELBI was used to select CPG with score over 60 in methodological rigor and applicability to the Colombian health system. Smoking cessation rates at 6 months were assessed according to counseling provider, model, and format. In total 5 CPG out of 925 references were selected comprising 44 systematic reviews and meta-analyses. RESULTS: Physician brief counseling and trained health professionals' intensive counseling (individual, group, proactive telephone) are effective with abstinence rates between 2.1% and 17.4%. Only practical counseling and motivational interview were found effective intensive interventions. The clinical effect of smoking cessation counseling is low and long term cessation rates uncertain. CONCLUSION: Cost-effectiveness analyses are recommended for the implementation of counseling in public health programs.
