ABSTRACT
OBJECTIVE: Medical nutrition therapy provides the opportunity to compensate for muscle wasting and immune response activation during stress and trauma. The objective of this systematic review is to assess the safety and effectiveness of early enteral nutrition (EEN) in adults with sepsis or septic shock. METHODS: The MEDLINE, Embase, CENTRAL, CINAHL, ClinicalTrials.gov, and ICTRP tools were searched from inception until July 2023. Conference proceedings, the reference lists of included studies, and expert content were queried to identify additional publications. Two review authors completed the study selection, data extraction, and risk of bias assessment; disagreements were resolved through discussion. Inclusion criteria were randomized controlled trials (RCTs) and non-randomized studies (NRSs) comparing the administration of EEN with no or delayed enteral nutrition (DEE) in adult populations with sepsis or septic shock. RESULTS: Five RCTs (n = 442 participants) and ten NRSs (n = 3724 participants) were included. Low-certainty evidence from RCTs and NRSs suggests that patients receiving EEN could require fewer days of mechanical ventilation (MD -2.65; 95% CI, -4.44-0.86; and MD -2.94; 95% CI, -3.64--2.23, respectively) and may show lower SOFA scores during follow-up (MD -1.64 points; 95% CI, -2.60--0.68; and MD -1.08 points; 95% CI, -1.90--0.26, respectively), albeit with an increased frequency of diarrhea episodes (OR 2.23, 95% CI 1.115-4.34). Even though the patients with EEN show a lower in-hospital mortality rate both in RCTs (OR 0.69; 95% CI, 0.39-1.23) and NRSs (OR 0.89; 95% CI, 0.69-1.13), this difference does not achieve statistical significance. There were no apparent differences for other outcomes. CONCLUSIONS: Low-quality evidence suggests that EEN may be a safe and effective intervention for the management of critically ill patients with sepsis or septic shock.

Background: In 131I therapies internal dosimetry is crucial for determining the mean absorbed dose to organs at risk, particularly the bone marrow, which has a dose constraint of 2 Gy. Traditionally, multicompartmental models have been used for bone marrow dosimetry, necessitating whole-body absorbed-dose assessments. However, noninvasive techniques, such as γ-camera scans or ceiling-mounted Geiger-Müller (GM) counters, can estimate the aforementioned. This study was aimed to evaluate the agreement between whole-body mean absorbed dose using γ-camera scans and ceiling-mounted GM in patients with thyroid carcinoma undergoing 131I therapy. Methods: This study included 31 patients with thyroid cancer who were treated with 131I. The whole-body time-integrated activity (TIA) and mean absorbed dose were estimated using the elimination curves obtained with γ-camera scans and ceiling-mounted GM. In addition, statistical analysis was performed on the data to determine the Coefficient Correlation Coefficient and the Bland-Altman limits of agreement for both parameters, as well as for the elimination curves' effective half-life. Results: The study revealed correlations of 0.562 and 0.586 between whole-body TIA and mean absorbed dose, respectively. The Bland-Altman limits of agreement were found to be below -3.75% and within 12.75% of the bone marrow dose constraint of 2 Gy. The nonparametric evaluation revealed that whole-body TIA and mean absorbed dose medians from GM were lower than those from γ-camera scans (p < 0.001). Effective half-life estimation mean was significantly lower in the GM than in the γ-camera of 13 and 23 h. Conclusions: Although GM calculates the whole-body absorbed dose with margins of error within clinical acceptance, underestimation of the effective half-life makes it an unacceptable substitute method for γ-cameras in clinical practice. Further research should be conducted to evaluate single-point GM measurement substitutions in time-activity curves.

Objectives: To generate evidence-based recommendations through formal consensus regarding the treatment of upper urinary tract infections during gestation. Materials and methods: Experts in microbiology, public health, internal medicine, infectious diseases, obstetrics, maternal fetal medicine and obstetric and gynecological infections participated in the consensus development group. The group also included professionals with training in clinical epidemiology, systematic data search, and representatives from the Health Secretariat and the Bogota Obstetrics and Gynecology Association. The participants disclosed their conflicts of interest. Starting with a clinical question, outcomes were graded and a systematic search was conducted in the Medline via PubMed, Embase, Lilacs, and Bireme databases. The search was expanded to include institutional repositories and antimicrobial resistance surveillance systems, with no language or date restrictions. The search was updated on October 1, 2022. The GRADE (Grading of Recommendations Assessment, Development and Evaluation) methodology was used to assess the quality of the evidence and determine the strength of the recommendations. Finally, the RAND/UCLA (Research and Development/University of California Los Angeles) methodology was applied for the formal consensus. This document was reviewed by academic peers before publication. Results: The following are the consensus recommendations. Recommendation 1. The initial management of pregnant women with upper urinary tract infections (UTIs) should be approached in a hospital setting. Recommendation 2. The use of second generation cephalosporins is the suggested first option for empirical antimicrobial management in pregnant women with upper UTI in order to improve the rates of clinical and microbiological cure. Recommendation 3. Because of the risk-benefit balance, the use of aminoglycosides is suggested as a second option for empirical antimicrobial treatment in pregnant women presenting with upper UTIs in the second and third trimester. Recommendation 4. The use of third-generation cephalosporins is suggested as the third option for empirical antimicrobial treatment in pregnant women with upper UTIs given that the risk of inducing microbial resistance is high with this group of antibiotics. Recommendation 5. The use of carbapenems is suggested as a first option in pregnant women with upper UTIs and a history of infections caused by microorganisms with resistance to third or fourth-generation cephalosporins. Recommendation 6. The use of aminoglycosides or fourth-generation cephalosporins is suggested as a second option in pregnant women with upper UTIs and a history of infection caused by microorganisms with resistance to third-generation cephalosporins, taking risk-benefit into account. Recommendation 7. The use of piperacillin/tazobactam is suggested as a third option in pregnant women with upper UTIs and a history of infection caused by microorganisms with resistance to third or fourthgeneration cephalosporins. Recommendation 8. Getting a urine culture is recommended in pregnant women with upper UTIs before initiating empirical antimicrobial treatment. Recommendation 9. In pregnant women with upper UTIs, it is suggested to modify therapy in accordance with the results of the sensitivity test when the culture report shows resistance to the antimicrobial agent initiated empirically. Recommendation 10. In pregnant women hospitalized due to upper UTIs, it is suggested to switch to oral antimicrobial therapy after at least 48 hours of modulation of the systemic inflammatory response and the clinical signs of infection, and when tolerance to oral intake is adequate. Recommendation 11. In pregnant women with upper UTIs with no complications secondary to the primary infection, it is recommended to administer antibiotic therapy for a period of 7 to 10 days. Conclusions: It is expected that with this Colombian upper UTI consensus variability in clinical practice will be reduced. It is recommended that groups doing research in maternal fetal medicine assess the implementation and effectiveness of these recommendations.

Como primera opción, se sugiere que el tratamiento antimicrobiano empírico de la gestante con IVU altas se realice con el uso de cefalosporinas de segunda generación con el fin de mejorar la tasa de cura clínica y microbiológica. Recomendación 3. Como segunda opción, se sugiere que el tratamiento antimicrobiano empírico de la gestante con IVU altas en el segundo y tercer trimestre se realice con aminoglucósidos dado su balance riesgo-beneficio. Recomendación 4. Como tercera opción, se sugiere que el tratamiento antimicrobiano empírico de la gestante con IVU altas se realice con el uso de cefalosporinas de tercera generación, debido a que el riesgo de inducción de resistencia microbiana es alto con este grupo de antibióticos. Recomendación 5. Como primera opción, en mujeres gestantes con IVU altas y antecedente de infección por microorganismos con resistencia a cefalosporinas de tercera o cuarta generación se sugiere el uso de carbapenémicos. Recomendación 6. Como segunda opción, en gestantes con IVU altas y antecedente de infección por microorganismos con resistencia a cefalosporinas de tercera generación se sugiere el uso de aminoglucósidos o cefalosporinas de cuarta generación teniendo en cuenta el riesgo-beneficio. Recomendación 7. Como tercera opción, en gestantes con IVU altas y antecedente de infección por microorganismos con resistencia a cefalosporinas de tercera o cuarta generación se sugiere el uso de piperacilina/tazobactam. Recomendación 8. En gestantes con IVU altas se recomienda realizar urocultivo previo al inicio de tratamiento antimicrobiano empírico. Recomendación 9. En gestantes con IVU altas, cuando el urocultivo reporte resistencia al antimicrobiano iniciado de forma empírica, se sugiere modificar la terapia guiada por los resultados del antibiograma. Recomendación 10. En la gestante hospitalizada por IVU altas se sugiere realizar el cambio de terapia antimicrobiana a vía oral cuando la paciente tenga, al menos, 48 horas de modulación de respuesta inflamatoria sistémica y de los signos clínicos de infección, así como adecuada tolerancia a vía oral. Recomendación 11. En gestantes con IVU altas, sin complicaciones secundarias a la infección primaria, se recomienda que la terapia antibiótica se administre de 7 a 10 días. Conclusiones: se espera que este consenso colombiano de IVU altas reduzca la variabilidad en la práctica clínica. Se recomienda a los grupos de investigación en medicina materno fetal e infectología evaluar la implementación y efectividad de las recomendaciones emitidas.

Background: Primary screening with Human Papilloma Virus (HPV) testing was introduced in Colombia in 2014 for individuals between 30 and 65 years of age. When the result is positive, cytology triage is performed for colposcopy referral. The convenience of initiating HPV-DNA testing for screening at 25 years of age is currently a subject of discussion. Therefore, the objective of this health technology assessment (HTA) is to analyze the available evidence regarding safety, efficacy, cost-effectiveness, values and preferences, ethical dilemmas and considerations pertaining to the implementation of the HPV-DNA test as a cervical screening strategy in women under 30 years of age in the Colombian context. Domains to be assessed: Clinical efficacy and safety 1. Cumulative rate of cervical intraepithelial neoplasia (CIN) grade 2 or high-er after 2 screening rounds. 2. Cumulative rates of invasive cancer of the uterine cervix after 2 screening rounds. 3. Safety: referral to colposcopy. Cost-effectiveness Cost-effectiveness for Colombia. Other domains considered Ethical considerations associated with cervical screening in women under 30 years of age. Organizational and individual considerations. Barriers and facilitators pertaining to the implementation of cervical screening in women under 30 years of age in the Colombian context. Methods: Clinical efficacy and safety assessment A systematic literature search of systematic reviews and clinical trials was conducted in MEDLINE, Embase and CENTRAL. The body of evidence was rated using the GRADE approach. An interdisciplinary team was then convened to create a working group to review the retrieved evidence. This led to the discussion and construction of the conclusions following the guidelines of a formal consensus in accordance with the RAND/UCLA methodology. Economic study Systematic literature research of studies that had assessed cost-effectiveness for Colombia. Results: Clinical outcomes An integrative analysis of 5 randomized clinical trials that met the inclusion critera was performed. Compared with cytology, primary HPV-DNA testing in women under 30 years of age could be associated with a lower frequency of CIN+2 lesions during the first screening round (RR: 1.57; CI: 1.20 to 2.04; low evidence certainty), and a lower incidence of CIN+2 (RR: 0.67; CI: 0.48 to 0.92; low evidence certainty). Moreover, it is associated with a lower frequency of invasive carcinoma at the end of follow-up (RR: 0.19; CI: 0.07 to 0.53; high evidence certainty). Economic results From the financial point of view, the use of HPVDNA testing plus cytology-based triage starting at 25 years of age is perhaps the most cost-effective option for Colombia (incremental cost-effectiveness ratio, COP 8,820,980 in 2013). Other implications Two studies suggest that barriers to implementation attributable to intermediation, public unrest and geographic considerations could be overcome with the use of new screening technologies or strategies. It is important to consider administration and service provision alternatives in order to overcome some acceptability and access barriers. Any cervical screening program must take into consideration ethical principles of nonmaleficence, beneficence, autonomy and equity. Future studies should focus on analyzing new screening techniques with emphasis on the population under 30 years of age. Conclusions: The use of HPV-DNA testing as a screening strategy in women under 30 years of age is a potentially efficacious and cost-effective intervention for Colombia. Future studies should focus on analyzing new screening technologies, with emphasis on the population under 30 years of age.
Antecedentes: A partir del 2014 en Colombia se incorporó la Tamización primaria con prueba de Virus del Papiloma Humano (VPH) desde los 30 hasta los 65 años, cuando la prueba es positiva se hace triage con citología para remisión a colposcopia. Actualmente se discute la conveniencia de iniciar la tamización con prueba de ADN de VPH a partir de los 25 años. De esta manera, el objetivo de esta evaluación de tecnologías sanitarias es analizar la evidencia disponible en torno a la seguridad, efectividad, costoefectividad, valores y preferencias, dilemas éticos y aspectos relacionados con la implementación para el contexto colombiano de la prueba ADN-VPH como estrategia de tamización cervical en mujeres menores de 30 años. Dominios a evaluar: Eficacia clínica y seguridad 1. Tasa acumulada de neoplasia intraepitelial cervical (NIC) grado 2 o más avanzado luego de 2 rondas de tamización. 2. Tasas acumuladas de cáncer invasor de cérvix luego de 2 rondas de tamización. 3. Seguridad: remisión a colposcopia. Costo-efectividad Costo efectividad para Colombia. Otros dominios considerados Aspectos éticos asociados a la tamización cervical en mujeres menores de 30 años. Aspectos organizacionales y del individuo. Barreras y facilitadores relacionados con la implementación en el contexto colombiano de la tamización cervical en mujeres menores de 30 años. Métodos: Evaluación de efectividad y seguridad clínicas Se realizó una búsqueda sistemática de la literatura en MEDLINE, Embase y CENTRAL de revisiones sistemáticas y ensayos clínicos. Se calificó el cuerpo de la evidencia con la aproximación GRADE. Posteriormente, se convocó a un grupo interdisciplinario a una mesa de trabajo en donde se presentó la evidencia recuperada, dando paso a la discusión y a la construcción de las conclusiones, siguiendo los lineamientos de un consenso formal acorde a la metodología RAND/UCLA. Estudio económico Se hizo una búsqueda sistemática de la literatura de estudios que hubieran evaluado el costo-efectividad para Colombia. Resultados: De 7.659 referencias recuperadas se incluyeron 8 estudios. Resultados clínicos Se realizó un análisis integrativo de 5 ensayos clínicos aleatorizados que cumplieron con los criterios de inclusión. Cuando se compara frente a la citología, la tamización primaria con ADN-VPH en mujeres menores de 30 años, podría asociarse con una mayor frecuencia de detección de lesiones NIC2+ durante la primera ronda de cribado (RR: 1.57; IC: 1,20 a 2,04; certeza en la evidencia baja), con una menor incidencia de NIC2+ (RR:0,67; IC: 0,48 a 0,92; certeza en la evidencia baja) y se asocia con una menor frecuencia de carcinoma invasor al término del seguimiento (RR: 0,19; IC: 0,07 a 0,53; certeza en la evidencia alta). Resultados económicos Desde el punto de vista económico, la alternativa de ADN-VPH y triage con citología desde los 25 años quizás representa la alternativa más costo-efectiva para Colombia (razón costo-efectividad incremental $8.820.980 COP año 2013). Otras implicaciones Dos estudios sugieren que las barreras de implementación, atribuibles a circunstancias de intermediación, de orden público y de carácter geográfico, podrían ser solventadas por nuevas tecnologías o estrategias de cribado. Es importante considerar alternativas de forma de administración y de prestación de servicios para solventar algunas barreras de aceptabilidad y acceso. Todo programa de tamización cervical debe contemplar los principios éticos de no maleficencia, beneficencia, autonomía y equidad. Futuros estudios deben enfocarse en analizar nuevas tecnologías de cribado con énfasis en población menor de 30 años. Conclusiones: El uso de la prueba ADN-VPH como estrategia de tamización en mujeres menores de 30 años es una intervención probablemente efectiva y costoefectiva para Colombia. Futuros estudios deben enfocarse en analizar nuevas tecnologías de cribado con énfasis en población menor de 30 años.

Objective: To estimate the burden of Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Treponema pallidum (TP), and human papillomavirus (HPV) infections among people aged 10 to 25 in Latin America and the Caribbean. Methods: The MEDLINE, EMBASE, and LILACS databases were searched, as well as documents from regional organizations or national health Institutions. Population-based studies that reported prevalence or incidence of CT, NG, TP, and HPV detected through confirmatory tests in adolescents and young people were included. Two reviewers independently selected studies and extracted data. The quality of studies was assessed using the Newcastle-Ottawa Scale. Pooled estimators were calculated in cases where heterogeneity was <70%; when not feasible, prevalence ranges were reported. Results: Out of a total of 3 583 references, 15 prevalence studies complied with the inclusion criteria. Due to substantial heterogeneity (>70%), it was not possible to pool frequency estimators. Among the general population, the prevalence of CT infection ranged between 2.1% and 30.1% (9 studies, 5 670 participants); for NG, prevalence ranged between 0% and 2.9% (8 studies, 5 855 participants); for TP, prevalence varied between 0% and 0.7% (3 studies, 11 208 participants), and for HPV infection, prevalence ranged between 25.1% and 55.6% (8 studies, 3 831 participants). Conclusions: Reliable, population-based data on sexually transmitted infections (STIs) in adolescents and youth in Latin America and the Caribbean are limited. Additional studies are needed to better understand the burden of STIs in this population. However, given the substantial prevalence of STIs detected, countries need public health policies for prevention, early diagnosis, and treatment of STIs in young people.

[ABSTRACT]. Objective. To estimate the burden of Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Treponema pallidum (TP), and human papillomavirus (HPV) infections among people aged 10 to 25 in Latin America and the Caribbean. Methods. The MEDLINE, EMBASE, and LILACS databases were searched, as well as documents from regional organizations or national health Institutions. Population-based studies that reported prevalence or incidence of CT, NG, TP, and HPV detected through confirmatory tests in adolescents and young people were included. Two reviewers independently selected studies and extracted data. The quality of studies was assessed using the Newcastle–Ottawa Scale. Pooled estimators were calculated in cases where heterogeneity was <70%; when not feasible, prevalence ranges were reported. Results. Out of a total of 3 583 references, 15 prevalence studies complied with the inclusion criteria. Due to substantial heterogeneity (>70%), it was not possible to pool frequency estimators. Among the general population, the prevalence of CT infection ranged between 2.1% and 30.1% (9 studies, 5 670 participants); for NG, prevalence ranged between 0% and 2.9% (8 studies, 5 855 participants); for TP, prevalence varied between 0% and 0.7% (3 studies, 11 208 participants), and for HPV infection, prevalence ranged between 25.1% and 55.6% (8 studies, 3 831 participants). Conclusions. Reliable, population-based data on sexually transmitted infections (STIs) in adolescents and youth in Latin America and the Caribbean are limited.

[RESUMEN]. Objetivo. Calcular la carga de infecciones por Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Treponema pallidum (PT) y el virus del papiloma humano (VPH) en personas de edades comprendidas entre los 10 y los 25 años en América Latina y el Caribe. Métodos. Se realizaron búsquedas en las bases de datos MEDLINE, EMBASE y LILACS, así como en documentos de organizaciones regionales o instituciones nacionales de salud. Se incluyeron estudios poblacionales que notificaron la prevalencia o la incidencia de CT, NG, TP y VPH, detectados mediante pruebas confirmatorias en adolescentes y jóvenes. Dos revisores seleccionaron de forma independiente los estudios y extrajeron los datos. La calidad de los estudios se evaluó mediante la escala de Newcastle-Ottawa. Se hicieron estimaciones combinadas en los casos en que la heterogeneidad era <70 %; cuando no era posible, se presentaron los rangos de prevalencia. Resultados. De un total de 3 583 referencias, 15 estudios de prevalencia cumplieron los criterios de inclusión. Debido a una significativa heterogeneidad (>70%), no fue posible agrupar las estimaciones de frecuencia. En la población general, la prevalencia de infección por CT fluctuó entre 2,1 % y 30,1 % (9 estudios y 5 670 participantes); en el caso de NG, la prevalencia fluctuó entre 0 % y 2,9 % (8 estudios y 5 855 participantes); en el caso de PT, la prevalencia varió entre 0 % y 0,7 % (3 estudios y 11 208 participantes) y en el caso de infección por VPH, la prevalencia fluctuó entre 25,1 % y 55,6 % (8 estudios y 3 831 participantes). Conclusiones. Los datos poblacionales fiables sobre las infecciones de transmisión sexual (ITS) en adolescentes y jóvenes en América Latina y el Caribe son limitados. Es necesario hacer estudios adicionales para comprender mejor la carga de las ITS en este grupo poblacional. Sin embargo, dada la significativa prevalencia de ITS detectada, los países requieren políticas de salud pública para la prevención, el diagnóstico temprano y el tratamiento de las ITS en la población joven.
[RESUMO]. Objetivo. Estimar a carga de infecção por Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Treponema pallidum (TP) e papilomavírus humano (HPV) na população entre 10 e 25 anos de idade na América Latina e no Caribe. Métodos. Foi realizada uma pesquisa nas bases de dados MEDLINE, EMBASE e LILACS, assim como da documentação de entidades regionais ou nacionais que atuam na área da saúde. Foram incluídos na revisão estudos populacionais que registraram a incidência ou a prevalência de infecção por CT, NG, TP e HPV, verificada por meio de exames confirmatórios realizados em adolescentes e jovens. Dois revisores trabalharam de modo independente na seleção dos estudos e extração dos dados. A qualidade dos estudos foi avaliada utilizando a Escala de Newcastle-Ottawa. Foi feito o cálculo dos estimadores combinados quando a heterogeneidade era <70% e apresentada a variação da prevalência nos outros casos quando essa estimativa não foi possível. Resultados. Das 3 583 referências levantadas, 15 eram estudos de prevalência que satisfizeram os critérios de inclusão. Devido à heterogeneidade considerável entre os estudos (>70%), não foi possível combinar os estimadores de frequência. Na população geral, a prevalência de infecção por CT variou entre 2,1% e 30,1% (9 estudos, 5 670 participantes); a de NG, entre 0 e 2,9% (8 estudos, 5 855 participantes); a de TP, entre 0 e 0,7% (3 estudos, 11 208 participantes); e a de infecção por HPV, entre 25,1% e 55,6% (8 estudos, 3 831 participantes).

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.

ABSTRACT Objective. To estimate the burden of Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Treponema pallidum (TP), and human papillomavirus (HPV) infections among people aged 10 to 25 in Latin America and the Caribbean. Methods. The MEDLINE, EMBASE, and LILACS databases were searched, as well as documents from regional organizations or national health Institutions. Population-based studies that reported prevalence or incidence of CT, NG, TP, and HPV detected through confirmatory tests in adolescents and young people were included. Two reviewers independently selected studies and extracted data. The quality of studies was assessed using the Newcastle-Ottawa Scale. Pooled estimators were calculated in cases where heterogeneity was <70%; when not feasible, prevalence ranges were reported. Results. Out of a total of 3 583 references, 15 prevalence studies complied with the inclusion criteria. Due to substantial heterogeneity (>70%), it was not possible to pool frequency estimators. Among the general population, the prevalence of CT infection ranged between 2.1% and 30.1% (9 studies, 5 670 participants); for NG, prevalence ranged between 0% and 2.9% (8 studies, 5 855 participants); for TP, prevalence varied between 0% and 0.7% (3 studies, 11 208 participants), and for HPV infection, prevalence ranged between 25.1% and 55.6% (8 studies, 3 831 participants). Conclusions. Reliable, population-based data on sexually transmitted infections (STIs) in adolescents and youth in Latin America and the Caribbean are limited. Additional studies are needed to better understand the burden of STIs in this population. However, given the substantial prevalence of STIs detected, countries need public health policies for prevention, early diagnosis, and treatment of STIs in young people.
RESUMEN Objetivo. Calcular la carga de infecciones por Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Treponema pallidum (PT) y el virus del papiloma humano (VPH) en personas de edades comprendidas entre los 10 y los 25 años en América Latina y el Caribe. Métodos. Se realizaron búsquedas en las bases de datos MEDLINE, EMBASE y LILACS, así como en documentos de organizaciones regionales o instituciones nacionales de salud. Se incluyeron estudios poblacionales que notificaron la prevalencia o la incidencia de CT, NG, TP y VPH, detectados mediante pruebas confirmatorias en adolescentes y jóvenes. Dos revisores seleccionaron de forma independiente los estudios y extrajeron los datos. La calidad de los estudios se evaluó mediante la escala de Newcastle-Ottawa. Se hicieron estimaciones combinadas en los casos en que la heterogeneidad era <70 %; cuando no era posible, se presentaron los rangos de prevalencia. Resultados. De un total de 3 583 referencias, 15 estudios de prevalencia cumplieron los criterios de inclusión. Debido a una significativa heterogeneidad (>70%), no fue posible agrupar las estimaciones de frecuencia. En la población general, la prevalencia de infección por CT fluctuó entre 2,1 % y 30,1 % (9 estudios y 5 670 participantes); en el caso de NG, la prevalencia fluctuó entre 0 % y 2,9 % (8 estudios y 5 855 participantes); en el caso de PT, la prevalencia varió entre 0 % y 0,7 % (3 estudios y 11 208 participantes) y en el caso de infección por VPH, la prevalencia fluctuó entre 25,1 % y 55,6 % (8 estudios y 3 831 participantes). Conclusiones. Los datos poblacionales fiables sobre las infecciones de transmisión sexual (ITS) en adolescentes y jóvenes en América Latina y el Caribe son limitados. Es necesario hacer estudios adicionales para comprender mejor la carga de las ITS en este grupo poblacional. Sin embargo, dada la significativa prevalencia de ITS detectada, los países requieren políticas de salud pública para la prevención, el diagnóstico temprano y el tratamiento de las ITS en la población joven.
RESUMO Objetivo. Estimar a carga de infecção por Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Treponema pallidum (TP) e papilomavírus humano (HPV) na população entre 10 e 25 anos de idade na América Latina e no Caribe. Métodos. Foi realizada uma pesquisa nas bases de dados MEDLINE, EMBASE e LILACS, assim como da documentação de entidades regionais ou nacionais que atuam na área da saúde. Foram incluídos na revisão estudos populacionais que registraram a incidência ou a prevalência de infecção por CT, NG, TP e HPV, verificada por meio de exames confirmatórios realizados em adolescentes e jovens. Dois revisores trabalharam de modo independente na seleção dos estudos e extração dos dados. A qualidade dos estudos foi avaliada utilizando a Escala de Newcastle-Ottawa. Foi feito o cálculo dos estimadores combinados quando a heterogeneidade era <70% e apresentada a variação da prevalência nos outros casos quando essa estimativa não foi possível. Resultados. Das 3 583 referências levantadas, 15 eram estudos de prevalência que satisfizeram os critérios de inclusão. Devido à heterogeneidade considerável entre os estudos (>70%), não foi possível combinar os estimadores de frequência. Na população geral, a prevalência de infecção por CT variou entre 2,1% e 30,1% (9 estudos, 5 670 participantes); a de NG, entre 0 e 2,9% (8 estudos, 5 855 participantes); a de TP, entre 0 e 0,7% (3 estudos, 11 208 participantes); e a de infecção por HPV, entre 25,1% e 55,6% (8 estudos, 3 831 participantes). Conclusões. Faltam dados populacionais confiáveis relativos a infecções sexualmente transmissíveis (ISTs) em adolescentes e jovens na América Latina e no Caribe. Outros estudos devem ser realizados para um entendimento melhor da carga dessas infecções na população. Diante da elevada prevalência verificada, os países precisam dispor de políticas de saúde pública para prevenção, diagnóstico precoce e tratamento de ISTs na população jovem.'
ABSTRACT
BACKGROUND: The staging of breast cancer has been based on tumor size, lymph node involvement, and presence or absence of distant metastases. The American Joint Committee on Cancer (AJCC) staging system in its eighth edition incorporates hormone receptors, human epidermal growth factor receptor 2 (HER2), and histologic grade due to their prognostic importance. In Latin America, however, the impact of the new edition is unknown. This article evaluates the performance of the AJCC eighth-edition staging system in a cohort of patients with breast cancer at a reference center in Colombia. METHODS: The study investigated a descriptive cohort of 912 patients who received complete treatment for non-metastatic invasive breast cancer and had information on the anatomic stage and biologic factors,. All the patients were restaged using the AJCC eighth-edition classification. Changes in clinical stages and differences between the two classifications were compared. RESULTS: The study enrolled 912 patients. Changes in staging occurred for 54.82% (downstaging for 40.3% and upstaging for 14.47%) of these patients. For recurrence-free survival, the C-Index of the eighth-edition AJCC was 0.726, and the AIC was 1323.7, whereas the C-Index of the seventh-edition AJCC was 0.731, and the AIC was 1314.3 (p = 0.99). CONCLUSIONS: The seventh and eighth editions of the AJCC staging system have similar predictive values in our population for recurrence-free survival. Future studies are necessary to evaluate the performance of the AJCC eighth-edition staging system in predicting overall survival.

Acute appendicitis is the most frequent urgent abdominal surgical pathology in children. Therapeutic decisions in patients who have undergone an appendectomy are made based on the macroscopic findings at the moment of surgery. There is high variability between surgical and histopathological findings. METHOD: Concordance among surgeons and pathologists regarding the diagnosis and classification of acute appendicitis was assessed in children who have undergone an appendectomy. Surgical site infection (SSI) incidence was measured for both the surgical and pathological classification. RESULTS: The statistical analysis included 1092 children. The pathologists confirmed the presence of appendicitis in 90.4% of the patients. Concordance in the diagnosis of appendicitis among surgeons and pathologists was weak (kappa 0.57), while concordance in the classification of perforated or non-perforated appendicitis was moderate (kappa 0.7). There were no significant differences in these findings determined by the surgeons' experience or the open or laparoscopic approach. In the discordant group of 70 patients in which the surgeon classified the appendicitis as non-perforated but the pathologist classified as perforated, just one patient developed an intra-abdominal abscess. CONCLUSIONS: The classification of appendicitis as perforated or non-perforated shows moderate concordance between the surgical and histopathological diagnosis. This concordance is not determined by the surgeons' experience or the surgical approach. TYPE OF STUDY: Diagnostic Test LEVEL OF EVIDENCE: Level II.
