Resumen Objetivo: Generar recomendaciones basadas en la evidencia, para la prevención primaria y secundaria, el tratamiento de las lesiones preneoplásicas y el diagnóstico temprano del cáncer gástrico en población adulta, con el propósito de reducir la carga de la enfermedad. Materiales y métodos: El grupo desarrollador estuvo integrado por profesionales de la salud y tomadores de decisiones. Se construyeron preguntas clínicas contestables y se realizó la graduación de los desenlaces. Se elaboró la búsqueda de la información en MEDLINE; EMBASE y CENTRAL, siendo actualizada el 18 de octubre de 2018. La pesquisa también abarcó otras fuentes de información como la Revista Colombiana de Gastroenterología y la lectura en "bola de nieve" de las referencias incluidas. Se contactó a expertos en la materia con el objetivo de identificar estudios relevantes no publicados. Para la construcción de las recomendaciones, se realizó un consenso acorde con los lineamientos propuestos por la metodología GRADE, sopesando los beneficios, los efectos adversos derivados de la intervención, las preferencias de los pacientes y el potencial impacto de las intervenciones sobre los costos. Resultados: Se presenta la versión corta de la "Guía de práctica clínica para la prevención primaria, secundaria y diagnóstico temprano de cáncer gástrico", junto con su evidencia de soporte y respectivas recomendaciones. Conclusiones: Como recomendación central para la implementación, se recomienda erradicar la infección por H. pylori en los pacientes con o sin factores de riesgo, como estrategia de prevención de las condiciones precursoras de cáncer gástrico. La Guía deberá actualizarse en tres años.

Abstract Objetive: Generate recommendations for primary and secondary prevention, treatment of gastric preneoplastic lesions, and early diagnosis of gastric cancer in the adult population, to increase the detection of gastric cancer in early stages. Material and methods: The developer group was made up of health professionals, decision-makers, and a representative of the patients. Answerable clinical questions were constructed and outcomes were graded. The search for information in MEDLINE was carried out; EMBASE and CENTRAL, being updated on October 18, 2018. The search also covered other sources of information such as the Colombian Journal of Gastroenterology and the "snowball" reading of the references included. Experts in the field were contacted to identify studies. For the construction of the recommendations, a consensus was made according to the guidelines proposed by the GRADE methodology, weighing the benefits, the adverse effects derived from the intervention, the preferences of the patients, and the potential impact of the interventions on costs. Results: The short version of the "Clinical practice guidelines for the primary, secondary, and early diagnosis of gastric cancer" is presented together with its supporting evidence and respective recommendations. Conclusions: As a central recommendation for implementation, it is recommended to eradicate H. pylori infection in patients with or without risk factors in whom it is detected to prevent gastric cancer precursor conditions. The Guide will need to be updated in three years.

Resumo Objetivo Comparar os efeitos dos cuidados expectantes versus intervencionistas no manejo de gestantes com pré-eclâmpsia grave distante do termo. Fontes de dados Foi realizada uma busca eletrônica no Medical Literature Analysis and Retrieval System Online (MEDLINE), Excerpta Medica Database (EMBASE), Cochrane Central Register of Controlled Trials (CENTRAL), Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS, para o espanhol) acrônimo), Plataforma Internacional de Registro de Ensaios Clínicos da Organização Mundial da Saúde (OMS-ICTRP) e bancos de dados OpenGrey. Foram pesquisados os sites da Federação Internacional de Ginecologia e Obstetrícia (FIGO, por sua sigla em francês), do Royal College of Obstetricians e Ginecologistas (RCOG), do American College of Obstetricians e Ginecologistas (ACOG) e do Colombian Journal of Obstetrics and Gynecology (CJOG) procedimentos da conferência, sem restrições de idioma, até 25 de março de 2020. Seleção de estudos Ensaios clínicos randomizados (RCTs) e estudos controlados não randomizados (NRSs) foram incluídos. A abordagem de Classificação de Recomendações, Avaliação, Desenvolvimento e Avaliação (GRADE) foi usada para avaliar a qualidade da evidência. Coleta de dados Os estudos foram avaliados de forma independente quanto aos critérios de inclusão, extração de dados e risco de viés. As discordâncias foram resolvidas por consenso. Síntese de dados Quatro RCTs e seis NRS foram incluídos. Evidências de baixa qualidade dos ECRs mostraram que o cuidado expectante pode resultar em uma incidência menor de pontuações de aparência, pulso, careta, atividade e respiração (Apgar) <7 em 5 minutos (razão de risco [RR]: 0,48; intervalo de confiança de 95% [IC 95%]: 0,23% a 0,99) e um peso médio ao nascer superior (diferença média [MD]: 254,7 g; IC 95%: 98,5 ga 410,9 g). Evidências de qualidade muito baixa dos NRSs sugeriram que os cuidados expectantes podem diminuir as taxas de morte neonatal (RR: 0,42; IC de 95% 0,22 a 0,80), doença da membrana hialina (RR: 0,59; IC de 95%: 0,40 a 0,87) e admissão à assistência neonatal (RR: 0,73; IC 95%: 0,54 a 0,99). Nenhuma diferença materna ou fetal foi encontrada para outros resultados perinatais. Conclusão Em comparação com o manejo intervencionista, o cuidado expectante pode melhorar os resultados neonatais sem aumentar a morbidade e mortalidade materna.

Abstract Objective To compare the effects of expectant versus interventionist care in the management of pregnant women with severe preeclampsia remote from term. Data sources An electronic search was conducted in the Medical Literature Analysis and Retrieval System Online (MEDLINE), Excerpta Medica Database (EMBASE), Cochrane Central Register of Controlled Trials (CENTRAL), Latin American and Caribbean Health Sciences Literature (LILACS, for its Spanish acronym), World Health Organization’s International Clinical Trials Registry Platform (WHO-ICTRP), and Open- Grey databases. The International Federation of Gynecology and Obstetrics (FIGO, for its French acronym), Royal College of Obstetricians and Gynaecologists (RCOG), American College of Obstetricians and Gynecologists (ACOG), and Colombian Journal of Obstetrics and Gynecology (CJOG) websites were searched for conference proceedings, without language restrictions, up to March 25, 2020. Selection of studies Randomized clinical trials (RCTs), and non-randomized controlled studies (NRSs) were included. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach was used to evaluate the quality of the evidence. Data collection Studies were independently assessed for inclusion criteria, data extraction, and risk of bias. Disagreements were resolved by consensus. Data synthesis Four RCTs and six NRS were included. Low-quality evidence from the RCTs showed that expectant care may result in a lower incidence of appearance, pulse, grimace, activity, and respiration (Apgar) scores<7 at 5 minutes (risk ratio [RR]: 0.48; 95% confidence interval [95%CI]: 0.23%to 0.99) and a higher average birth weight (mean difference [MD]: 254.7 g; 95%CI: 98.5 g to 410.9 g). Very low quality evidence from the NRSs suggested that expectant care might decrease the rates of neonatal death (RR: 0.42; 95%CI 0.22 to 0.80), hyalinemembrane disease (RR: 0.59; 95%CI: 0.40 to 0.87), and admission to neonatal care (RR: 0.73; 95%CI: 0.54 to 0.99). Nomaternal or fetal differences were found for other perinatal outcomes. Conclusion Compared with interventionist management, expectant care may improve neonatal outcomes without increasing maternal morbidity and mortality.

Resumen Introducción. La infección asociada al catéter urinario es responsable de hasta un 30% de las infecciones nosocomiales. Al respecto, se ha descrito el uso de intervenciones no farmacológicas durante la inserción del catéter urinario para reducir la frecuencia de infecciones asociadas. Objetivo. Evaluar la seguridad y la efectividad de intervenciones no farmacológicas durante la inserción del catéter urinario diseñadas para reducir el riesgo de infección en adultos inmunocompetentes. Materiales y métodos. Se realizó una búsqueda en las bases de datos MEDLINE, Embase y LILACS. Se incluyeron ensayos clínicos aleatorizados que compararan el uso de intervenciones no farmacológicas con el uso de placebos, el uso de intervenciones farmacológicas o la ausencia de intervención durante la inserción del catéter. Resultados. Se encontraron ocho estudios (8 718 participantes). Con base en la evidencia encontrada (baja y muy baja calidad según la clasificación del sistema GRADE), el uso de intervenciones no farmacológica reduce la frecuencia de bacteriuria asintomática (RR 0.67; IC95%: 0.48-0.94; 7 estudios) o de eventos adversos menores (RR 0.84, IC95%: 0.74-0.96; 2 estudios), pero no disminuye la tasa de infecciones sintomáticas del tracto urinario (RR 0.90; IC95%: 0.61 a 1.35; 4 estudios), ni mejora las puntuaciones de calidad de vida (escala MD -0.01 EQ-5D, IC95%: (-0.03)-(0.01), 1 estudio). Conclusión. El uso de intervenciones no farmacológicas durante la inserción del catéter urinario no supone riesgo alguno y sí podría ayudar a disminuir la frecuencia infecciones asociadas a este procedimiento, tales como la bacteriuria asintomática y eventos adversos menores; sin embargo, hay poca evidencia, y de baja o muy baja calidad, para llegar a conclusiones sobre su efectividad.

Abstract Introduction: Catheter-associated urinary tract infections (CAUTI) account for up to 30% of hospital -acquired infections. In this regard, several studies have reported the use of non-pharmacological interventions during urinary catheter insertion aimed at reducing the occurrence rate of CAUTI. Objective: To assess the safety and effectiveness of non-pharmacological interventions during urinary catheter insertion aimed at reducing the risk of contracting infections in non-immunocompromised adults. Materials and methods: A literature review was conducted in the MEDLINE, Embase, and LILACS databases. Only randomized clinical trials comparing the use of non-pharmacological interventions to placebos, pharmacological interventions, or no intervention during catheter insertion were included. Results: Eight studies were retrieved (8 718 participants). Based on the evidence found in the review (low-quality and very low-quality evidence according to the GRADE system), using non-pharmacological interventions reduces the frequency of asymptomatic bacteriuria episodes (RR 0.67, 95%CI 0.48-0.94; 7 studies) or mild adverse events (RR 0.84, 95%CI 0.74-0.96; 2 studies), but does not reduce the occurrence rate of symptomatic urinary tract infections (RR 0.90, 95%CI 0.61-1.35; 4 studies) or improves quality-of-life scores (MD -0.01 EQ-5D scale; 95%CI (-0.03)-(0.01), 1 study). Conclusion: The use of non-pharmacological interventions during urinary catheter insertion does not pose any risk at all. Instead, it could help reduce the occurrence rate of infections associated with this procedure, such as asymptomatic bacteriuria and mild adverse events. However, there is very little evidence (in fact, low and very low-quality evidence) to make conclusions on the effectiveness of these interventions.

RESUMEN Objetivo: revisar los conceptos que subyacen al trabajo de parto con feto en presentación pelviana, su semiología y las maniobras obstétricas que facilitan un resultado materno perinatal exitoso. Materiales y métodos: a partir de un caso hipotético que ambienta de manera práctica el tema, se crea un documento explicativo construido a partir de una revisión narrativa, en donde se examinan los preceptos relacionados con el diagnóstico, el mecanismo del parto en presentación pelviana y el manejo intraparto de la gestante, con énfasis en la adecuada ejecución de las maniobras que facilitan la extracción fetal. Resultados: el parto en presentación pelviana debe ser atendido por vía vaginal cuando se encuentra en periodo expulsivo con encajamiento cumplido. Para su diagnóstico y atención es esencial hacer una adecuada identificación de la presentación, así como conocer su fisiología, la indicación y adecuada ejecución de las maniobras obstétricas que facilitan un parto sin complicaciones. Conclusiones: el mecanismo del parto en presentación pelviana es complejo y requiere, cuando no hay otra alternativa para la atención, que tanto el obstetra como el médico general conozcan su fisiología y las múltiples maniobras obstétricas que facilitan obtener buen resultado materno perinatal.

ABSTRACT Objective: To review the concepts underlying breech presentation delivery as well as the semiology and the obstetric maneuvers contributing to a successful perinatal maternal outcome. Materials and methods: Based on a hypothetical scenario to set the stage for a practical approach to the topic, an explanatory paper built on a narrative review is created in order to examine the principles related to diagnosis, mechanism of delivery and maternal care, emphasizing maneuvers to ease fetal extraction. Results: Breech presentation delivery must be managed through the vaginal canal when already in the expulsion phase with fetal engagement. For diagnosis and care, it is essential to know the unique semiology and physiology of this condition as well as the obstetric maneuvers to facilitate an uncomplicated delivery. Conclusions: The mechanism of childbirth in breech presentation is complex and requires knowledge of its physiology and multiple obstetric maneuvers on the part of the obstetrician as well as the general practitioner, in order to ensure adequate care when there is no other option.

Abstract OBJECTIVE: To analyze the epidemiological profile and trends of maternal deaths of women living in Bogotá during the 2010-2012 and 2013-2015 triennia. MATERIALS AND METHODS: Retrospective, cross-sectional and descriptive observational study based on epidemiological surveillance of sentinel cases. Women residing in Bogotá who died of direct or indirect causes were included. Late deaths were excluded. Maternal deaths were identified through a review of the birth and death database of the National Administrative Department of Statistics and the reports of the National Health Institute. Clinical and sociodemographic maternal variables grouped, and specific causes of death were recorded. A descriptive statistic was performed for the variables analyzed and statistical significance of trends was evaluated using Poisson distribution. RESULTS: 225 early maternal deaths and 630,017 live births were included. Early maternal mortality decreased from 39 to 32 per 100,000 live births. For the most part, the reduction occurred in women between 10 and 19 years old and in those over 40 years old. Maternal mortality due to indirect causes decreased and to a lesser extent, for hypertensive disorders, hemorrhage and pregnancy that ends in abortion. However, it increased for infections related to pregnancy and suicides. CONCLUSIONS: Bogotá is in a period of obstetric transition. The reduction in early maternal mortality and the fall in indirect causes stand out. Attention should be paid to the rise in deaths as a consequence of self-inflicted injuries.

Resumen OBJETIVO: Analizar el perfil epidemiológico y la tendencia de las muertes maternas tempranas de mujeres residentes en Bogotá durante los trienios 2010-2012 y 2013-2015. MATERIALES Y MÉTODOS: Estudio observacional, retrospectivo, transversal y analítico efectuado con base en la vigilancia epidemiológica de casos centinela. Criterio de inclusión: mujeres residentes en Bogotá, Colombia, fallecidas por causas directas o indirectas. Criterio de exclusión: muertes tardías. Las muertes maternas se identificaron mediante la revisión de la base de nacimientos y defunciones del Departamento Administrativo Nacional de Estadística y de los reportes del Instituto Nacional de Salud. Se registraron las variables clínicas y sociodemográficas maternas, causas agrupadas y específicas de muerte. Se realizó estadística descriptiva para las variables analizadas y la significación estadística se evaluó con distribución de Poisson. RESULTADOS: Se incluyeron 225 muertes maternas tempranas y 630,017 nacidos vivos. La mortalidad materna temprana disminuyó de 39 a 32 por cada 100,000 nacidos vivos. La mayor reducción se registró en mujeres de 10 a 19 y en mayores de 40 años. La mortalidad materna por causas indirectas disminuyó y, en menor medida, para los trastornos hipertensivos, hemorragia y embarazo que termina en aborto. No obstante, aumentaron las infecciones relacionadas con el embarazo y los suicidios. CONCLUSIONES: Bogotá se encuentra en un periodo de transición obstétrica. Sobresale la reducción en la mortalidad materna temprana y la caída en las causas indirectas. Debe prestarse atención al ascenso en las muertes como consecuencia de lesiones autoinfligidas.

Resumo Objetivo Identificar fatores maternos associados à presença de baixo peso ao nascer em neonatos a termo. Métodos Estudo de caso-controle realizado emuma instituição de alta complexidade localizada na cidade de Neiva, Colômbia. O estudo incluiu mulheres com gestação a termo e fetos vivos únicos. Pacientes com doenças prévias, provenientes de outras regiões, com gravidez resultante de reprodução assistida, ou com diagnóstico de anormalidade fetal ou aneuploidia foramexcluídos. O baixo peso ao nascer foi a variável dependente, e as variáveis independentes analisadas foram as características sociodemográficas e clínicas maternas. Razões de chance ajustadas e não ajustadas (RCa e RC) juntamente com os intervalos de confiança de 95% (IC 95%) foram relatadas. Resultados O estudo incluiu 270 participantes (90 casos e 180 controles). Controlando a idade materna, nível escolar, socioeconômico e civil, segurança social e a presença de doença materna durante a gestação, constatou-se que ganho de peso (RCa 0,77, IC 95% 0,70-0,85) e ausência de pré-natal (RCa 8,20, IC 95% 3,22-20,87) estavam entre os fatores associados ao baixo peso ao nascer. Conclusão As ausências de ganho ponderal e de pré-natal são fatores associados à presença de baixo peso ao nascer em recém-nascidos a termo e devem ser considerados na prática clínica.

Abstract Objective To identify maternal factors associated with the presence of low birth weight in term neonates. Methods Matched hospital-based case-controlled study performed in a high complexity institution located in the city of Neiva, Colombia. The study included women with term gestation and singleton live fetuses. Patients with prior diseases, coming from other regions, with pregnancy resulting from assisted reproduction, or with a diagnosis of fetal abnormality or aneuploidy were excluded. Low birth weight was the dependent variable, and the independent variables that were analyzed were maternal sociodemographic and clinical characteristics. Adjusted and non-adjusted odds ratios (aOR and OR) together with the 95% confidence intervals (95% CI) were reported. Results The study included 270 participants (90 cases and 180 controls). Controlling for maternal age, educational level, socioeconomic and civil status, social security and the presence of maternal disease during gestation, it was found that weight gain (aOR 0.77, 95% CI 0.70-0.85) and the absence of prenatal care (aOR 8.20, 95% CI 3.22-20.87) were among the factors associated with low birth weight. Conclusions The absence of weight gain and of prenatal care are factors associated with the presence of low birth weight in term neonates and should be considered in clinical practice.

Abstract Introduction: Sedation is a practice frequently used in multiple settings outside the operating room. Currently, it is employed by different interdisciplinary groups. It is imperative to ensure safe, standardized practices and proper training of the personnel involved. Objectives: To update available information, create minimum standards of care for performing high-quality sedation procedures based on the best available evidence. These standards lead to safe and effective care practices, reducing unjustified variability. Materials and methods: A group of different health professionals with experience in sedation outside the operating room and representatives of scientific and patient societies developed the guideline. Through a non-formal consensus of thematic and methodological experts, the content, scope and objectives, study populations, and questions to be examined were all defined. A systematic review of the literature was performed to formulate the recommendations with graduated levels of evidence in accordance with GRADE methodology. Results: A summarized version of the Clinical Practice Guideline with recommendations for the administration of sedation as part of diagnostic or therapeutic procedures outside the operating room in patients over the age of 12. Conclusions: The Clinical Practice Guideline presents evidence-based recommendations in order to standardize the procedure, improving the quality of care, and reducing morbidity of patients that require sedation outside of the operating room.
