Recurrence After Biopsy-Confirmed Cervical High-Grade Intraepithelial Lesion Followed by Negative Conization: A Systematic Review and Meta-analysis.

ABSTRACT: The aim of the study is to assess the recurrence rate (as cervical intraepithelial neoplasia 2+ [CIN2+]) in patients who had a confirmed high-grade squamous intraepithelial lesion (CIN2-3) in a cervical biopsy specimen followed by a negative conization specimen. MATERIALS AND METHODS: A systematic literature review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. Ovid/MEDLINE, Ovid/Embase, the Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov were searched from inception until January 2023. The study protocol was registered in PROSPERO (ID number CRD42023393951). The search identified 3,089 articles; 1,530 were removed as duplicates, and 1,559 titles and abstracts were assessed for inclusion. The full text of 26 studies was assessed for eligibility, and finally, 12 studies with 1,036 patients were included. All included studies were retrospective cohort studies. A proportion meta-analysis was performed. RESULTS: For patients with negative conization specimens, the recurrence rate as CIN2+ during follow-up was 6% (95% CI, 1.8%-12.1%; I2 = 49.2; p < .0001, 215 patients and 4 studies) in the proportion meta-analysis, ranging from 0.3% to 13.0% for the individual studies. For patients with ≤CIN1 conization specimens, the recurrence rate as CIN2+ during follow-up was 3.6% (95% CI, 1.2%-7%; I2 = 75.1; p < .0001, 991 patients and 10 studies) in the proportion meta-analysis and ranged from 0.6% to 13.0% for the individual studies. CONCLUSIONS: The recurrence rate as CIN2+ for patients with a confirmed high-grade intraepithelial lesion on a cervical biopsy followed by a negative conization specimen is 6%. In patients with negative and CIN1 conization specimens, the recurrence rate is 3.6%.

Diagnostic accuracy of sentinel lymph node frozen section analysis in patients with early-stage cervical cancer: A systematic review and meta-analysis.

OBJECTIVE: To assess the diagnostic accuracy of intraoperative SLN frozen section analysis compared with ultrastaging in patients with early-stage cervical cancer. METHODS: A systematic literature review was conducted following the PRISMA checklist. MEDLINE (via Ovid), Embase, and the Cochrane Central Register of Controlled Trials were searched from inception until February 2023. The inclusion criteria were patients with early-stage cervical cancer (2018 FIGO stage I-II), consisting of the histological subtype squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma (≥90% of the patients in each study), who underwent SLN detection (with any tracer) and intraoperative frozen section followed by SLN ultrastaging. Randomized controlled trials, prospective and retrospective observational studies were considered. The detection rates and measures of diagnostic accuracy were pooled using a random effects univariate model. A preplanned subgroup meta-analysis was conducted, with isolated tumor cells excluded as positive lymph nodes. The review was registered in PROSPERO (CRD42023397147). RESULTS: The search identified 190 articles, with 153 studies considered potentially eligible after removing duplicates. Fourteen studies met the selection criteria, including a total of 1720 patients. Seven studies were retrospective, and the other seven were prospective. Frozen section analysis detected 159 of 292 (54.5%) patients with lymph node metastases. In 281 patients the type of volume metastasis was reported: 1 of 41 (2.4%) patients had isolated tumor cells, 21 of 78 (26.9%) patients had micrometastases, and 133 of 162 (82.1%) patients had macrometastases. The pooled sensitivity of intraoperative SLN frozen section analysis was 65% (95% CI, 51-77%) for macrometastases, micrometastases, and isolated tumor cells. When we excluded patients with isolated tumor cells, the pooled sensitivity increased to 72% (95% CI, 60-82%). CONCLUSION: SLN frozen section detects 65% of lymph node metastases compared with SLN ultrastaging and may prevent unnecessary radical surgery in some patients with early-stage cervical cancer.

Definitive pelvic radiotherapy for patients with newly diagnosed stage IVB cervical cancer: a systematic review.

OBJECTIVE: The objective of this systematic review was to assess the oncologic outcomes of patients with International Federation of Gynecology and Obstetrics (FIGO) 2018 stage IVB cervical cancer receiving definitive pelvic radiotherapy compared with systemic chemotherapy (with or without palliative pelvic radiotherapy). METHODS: This study was registered in PROSPERO (registration number CRD42022333433). A systematic literature review was conducted following the MOOSE checklist. MEDLINE (through Ovid), Embase, and Cochrane Central Register of Controlled Trials were searched from inception until August 2022. The inclusion criteria were patients with metastatic FIGO 2018 stage IVB cervical cancer, a histologic subtype of squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma that received definitive pelvic radiotherapy (≥45 Gy) as part of management compared with systemic chemotherapy with or without palliative (30 Gy) pelvic radiotherapy. Randomized controlled trials and observational studies with two arms of comparison were considered. RESULTS: The search identified 4653 articles; 26 studies were considered potentially eligible after removing duplicates, and 8 met the selection criteria. In total, 2424 patients were included. There were 1357 and 1067 patients in the definitive radiotherapy and chemotherapy groups, respectively. All included studies were retrospective cohort studies, and two were database population studies. The median overall survival reported in seven studies for the definitive radiotherapy arm versus systemic chemotherapy groups were 63.7 months versus 18.4 months (p<0.01), 14 months versus 16 months (p value not reported), 17.6 months versus 10.6 months (p<0.01), 32 months versus 24 months (p<0.01), 17.3 months versus 10 months (p<0.01), and 41.6 months versus 17.6 months (p<0.01), and not reached versus 19 months (p=0.13) respectively, favoring the groups that received definitive pelvic radiotherapy. The high clinical heterogeneity precluded the performance of meta-analysis, and all studies were at serious risk of bias. CONCLUSIONS: Definitive pelvic radiotherapy as part of treatment in patients with stage IVB cervical cancer may improve oncologic outcomes compared with systemic chemotherapy (with or without palliative radiotherapy); however, this is based on low-quality data. Prospective evaluation would be ideal before the adoption of this intervention in standard clinical practice.

Consensus for the treatment of upper urinary tract infections during pregnancy / Consenso para el tratamiento de la infección de vías urinarias altas durante la gestación

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.

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.

Peritoneal carcinomatosis after minimally invasive surgery versus open radical hysterectomy: systematic review and meta-analysis.

OBJECTIVE: To assess the incidence of peritoneal carcinomatosis in patients undergoing minimally invasive or open radical hysterectomy for cervical cancer. METHODS: The MEDLINE (accessed through Ovid), Embase, Cochrane Central Register of Controlled Trials (CENTRAL), Clinical Trials, and Scopus databases were searched for articles published from inception up to April 2022. Articles published in English were considered. The included studies reported on patients with International Federation of Gynecology and Obstetrics (FIGO) 2009 stage IA-IIA squamous cell carcinoma, adenocarcinoma, and/or adenosquamous carcinoma of the cervix who underwent primary surgery. Studies had to report at least one case of peritoneal carcinomatosis as a recurrence pattern, and only studies comparing recurrence after minimally invasive surgery versus open surgery were considered. Variables of interest were manually extracted into a standardized electronic database. This study was registered in PROSPERO (CRD42022325068). RESULTS: The initial search identified 518 articles. After the removal of the duplicate entries from the initial search, two authors independently reviewed the titles and abstracts of the remaining 453 articles. Finally, 78 articles were selected for full-text evaluation; 22 articles (a total of 7626 patients) were included in the analysis-one randomized controlled trial and 21 observational retrospective studies. The most common histology was squamous cell carcinoma in 60.9%, and the tumor size was <4 cm in 92.8% of patients. Peritoneal carcinomatosis pattern represented 22.2% of recurrences in the minimally invasive surgery approach versus 8.8% in open surgery, accounting for 15.5% of all recurrences. The meta-analysis of observational studies revealed a statistically significant higher risk of peritoneal carcinomatosis after minimally invasive surgery (OR 1.90, 95% CI 1.32 to 2.74, p<0.05). CONCLUSION: Minimally invasive surgery is associated with a statistically significant higher risk of peritoneal carcinomatosis after radical hysterectomy for cervical cancer compared with open surgery.

Primary HPV-DNA screening in women under 30 years of age: health technology assessment / Tamización primaria con prueba ADN-VPH en mujeres menores de 30 años: evaluación de tecnología sanitaria

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.

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.

Exposure to armed conflict as a factor associated with very low birth weight: Case-control population study.

OBJECTIVE: To determine the association between armed conflict and very low birth wright (VLBW), which is a multifactorial etiology public health problem that includes aspects of poverty and violence. METHODS: Case-control population study matched by year of delivery conducted in Cauca, Colombia, between 2010 and 2016. Cases of VLBW, with weights between 500 and 1499 g and controls weighing between 2500 and 3999 g. Cases and controls were identified through the vital statistics registry, and exposure was determined using a multidimensional index designed by the Colombian State. Multiple gestations were excluded. Conditional logistic regression for matched data was used, adjusting for confounding variables. RESULTS: Overall, 7068 matched participants (1767 cases and 5301 controls) were included. Cases and controls had similar baseline characteristics. Participants were predominantly women in the second and third decades of life, 3222 (46%) were exposed to armed conflict, and 1902 (27%) were of African-Colombian or indigenous ethnicity. Maternal exposure to armed conflict significantly increased the odds of VLBW among women with rural birth (adjusted odds ratio [aOR] 3.86, 95% confidence interval [CI] 2.74-5.45) and inadequate prenatal care (aOR 10.38, 95% CI 8.20-13.12). CONCLUSION: Exposure to armed conflict increases the odds of VLBW neonates. This factor needs to be considered in prenatal care.

Spatulas for operative vaginal birth: A systematic review and meta-analysis.

BACKGROUND: Operative vaginal birth represents an alternative to address problems during the second stage of labor. Obstetricians have access to three different instruments: forceps, vacuum, and spatulas. OBJECTIVE: To evaluate the safety and effectiveness of the use of spatulas for operative vaginal birth. SEARCH STRATEGY: MEDLINE/PubMed, Embase, CENTRAL, LILACS, SciELO, ClinicalTrials.gov, and OpenGrey. SELECTION CRITERIA: Randomized controlled studies and non-randomized controlled studies (NRS) were included. DATA COLLECTION AND ANALYSIS: Studies were independently assessed for inclusion, data extraction, and risk of bias. MAIN RESULTS: Nine NRS (n = 16  497 women) compared the use of spatulas versus forceps. Low-certainty evidence suggests that spatulas were not different in terms of failed operative vaginal delivery rate (odds ratio [OR] 0.89, 95% confidence interval [CI] 0.53-1.52), but may decrease the incidence of birth canal trauma (OR 0.70, 95% CI 0.54-0.91), birth canal laceration (OR 0.50, 95% CI 0.28-0.91), and neonatal soft-tissue injury (OR 0.19, 95% CI 0.13-0.29). Six NRS (n = 2992 women) compared the use of spatulas versus vacuum. Low-quality evidence suggests that spatulas may decrease failed operative vaginal delivery rate (OR 0.10, 95% CI 0.04-0.26). There were no apparent differences in other maternal and neonatal outcomes. CONCLUSION: Low-certainty evidence suggests that spatulas could be a safe and effective alternative for operative vaginal birth.

Diagnostic Accuracy of Rapid Point-of-Care Tests for Detecting Active Syphilis: A Systematic Review and Meta-Analysis.

BACKGROUND: Syphilis represents an important cause of morbidity and mortality. Point-of-care (POC) test offers the advantages of diagnosing the condition and the possibility of starting treatment immediately. METHODS: MEDLINE, Embase, CENTRAL, LILACS, World Health Organization International Clinical Trials Registry Platform, Web of Science, OpenGrey, and DARE were searched without language restrictions from inception to September 30, 2020. Diagnostic test accuracy studies that enrolled men and nonpregnant women of reproductive age under field conditions were analyzed. Only studies wherein all the patients had undergone a rapid POC test and those that included the reference standard (treponemal plus nontreponemal test) were eligible for inclusion. Studies were independently assessed for inclusion, data extraction, and bias risk. The data from these studies were extracted for meta-analyses. The quality of the evidence was assessed using the GRADE approach. Registration Prospero CRD42018107532. RESULTS: Nine studies with 9666 participants were included. Nine POC brands were assessed. Sensitivities of the tests ranged from 0.67 to 1.00 and specificities from 0.93 to 1.00. The mean sensitivity and specificity of all the included studies was 0.86 (95% confidence interval, 0.79-0.91) and 0.98 (95% confidence interval, 0.96-0.99), respectively. CONCLUSIONS: Based on the results of this systematic review, the POC test for syphilis showed good sensitivity and excellent specificity.

Expectant Versus Interventionist Care in the Management of Severe Preeclampsia Remote from Term: A Systematic Review.

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 OpenGrey 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), hyaline membrane 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). No maternal 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.

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.
