RESUMO
OBJECTIVES: To explore obstetricians', midwives' and trainees' perceptions of caesarean section (CS) determinants in the context of public obstetric care services provision in Argentina. Our hypothesis is that known determinants of CS use may differ in settings with limited access to essential obstetric services. SETTING: We conducted a formative research study in 19 public maternity hospitals in Argentina. An institutional survey assessed the availability of essential obstetric services. Subsequently, we conducted online surveys and semistructured interviews to assess the opinions of providers on known CS determinants. RESULTS: Obstetric services showed an adequate provision of emergency obstetric care but limited services to support women during birth. Midwives, with some exceptions, are not involved during labour. We received 680 surveys from obstetricians, residents and midwives (response rate of 63%) and interviewed 26 key informants. Six out of 10 providers (411, 61%) indicated that the use of CS is associated with the complexities of our caseload. Limited pain management access was deemed a potential contributing factor for CS in adolescents and first-time mothers. Providers have conflicting views on the adequacy of training to deal with complex or prolonged labour. Obstetricians with more than 10 years of clinical experience indicated that fear of litigation was also associated with CS. Overall, there is consensus on the need to implement interventions to reduce unnecessary CS. CONCLUSIONS: Public maternity hospitals in Argentina have made significant improvements in the provision of emergency services. The environment of service provision does not seem to facilitate the physiological process of vaginal birth. Providers acknowledged some of these challenges.

BACKGROUND: Perineal pain is a common but poorly studied adverse outcome following childbirth. Pain may result from perineal trauma due to bruising, spontaneous tears, surgical incisions (episiotomies), or in association with operative vaginal births (ventouse or forceps-assisted births). This is an update of a review last published in 2013. OBJECTIVES: To determine the efficacy of a single administration of paracetamol (acetaminophen) used in the relief of acute postpartum perineal pain. SEARCH METHODS: For this update, we searched the Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (9 December 2019), and reference lists of retrieved studies. SELECTION CRITERIA: Randomised controlled trials (RCTs), including cluster-RCTs, comparing paracetamol to placebo. We excluded quasi-RCTs and cross-over trials. Data from abstracts would be included only if authors had confirmed in writing that the data to be included in the review had come from the final analysis and would not change. DATA COLLECTION AND ANALYSIS: Two review authors assessed each study for inclusion and extracted data. One review author reviewed the decisions and confirmed calculations for pain relief scores. We assessed the certainty of the evidence using the GRADE approach. MAIN RESULTS: This update identified no new trials so the results remain unchanged. However, by applying the GRADE assessment of the evidence, the interpretation of main results differed from previous version of this review. We identified 10 studies involving 2044 women, but all these studies involved either three or four groups, looking at differing drugs or doses. We have only included the 1301 women who were in the paracetamol versus placebo arms of the studies. Of these, five studies (482 women) assessed 500 mg to 650 mg and six studies (797 women) assessed 1000 mg of paracetamol. One study assessed 650 mg and 1000 mg compared with placebo and contributed to both comparisons. We used a random-effects meta-analysis because of the clinical variability among studies. Studies were from the 1970s to the early 1990s, and there was insufficient information to assess the risk of bias adequately, hence the findings need to be interpreted within this context. The certainty of the evidence for the two primary outcomes on which data were available was assessed as low, downgraded for overall unclear risk of bias and for heterogeneity (I² statistic 60% or greater). More women may experience pain relief with paracetamol compared with placebo (average risk ratio (RR) 2.14, 95% confidence interval (CI) 1.59 to 2.89; 10 trials, 1279 women), and fewer women may need additional pain relief with paracetamol compared with placebo (average RR 0.34, 95% CI 0.21 to 0.55; 8 trials, 1132 women). However, the certainty of the evidence was low, downgraded for unclear overall risk of bias and substantial heterogeneity. One study used the higher dose of paracetamol (1000 mg) and reported maternal drug adverse effects. There may be little or no difference in the incidence of nausea (average RR 0.18, 95% CI 0.01 to 3.66; 1 trial, 232 women; low-certainty evidence), or sleepiness (average RR 0.89, 95% CI 0.18 to 4.30; 1 trial, 232 women; low-certainty evidence). No other maternal adverse events were reported. None of the studies assessed neonatal drug adverse effects. AUTHORS' CONCLUSIONS: A single dose of paracetamol may improve perineal pain relief following vaginal birth, and may reduce the need for additional pain relief. Potential adverse effects for both women and neonates were not appropriately assessed. Any further trials should also address the gaps in evidence concerning maternal outcomes such as satisfaction with postnatal care, maternal functioning/well-being (emotional attachment, self-efficacy, competence, autonomy, confidence, self-care, coping skills) and neonatal drug adverse effects.

BACKGROUND: While cesarean section is an essential life-saving strategy for women and newborns, its current overuse constitutes a global problem. The aim of this formative research is to collect information from hospitals, health professionals and women regarding the use of cesarean section in Argentina. This article describes the methodology of the study, the characteristics of the hospitals and the profile of the participants. METHODS: This formative research is a mixed-method study that will be conducted in seven provinces of Argentina. The eligibility criteria for the hospitals are (a) use of the Perinatal Information System, (b) cesarean section rate higher than 27% in 2016, (c) ≥ 1000 deliveries per year. Quantitative and qualitative research techniques will be used for data collection and analysis. The main inquiry points are the determining factors for the use of cesarean section, the potential interventions to optimize the use of cesarean section and, in the case of women, their preferred type of delivery. DISCUSSION: It is expected that the findings will provide a situation diagnosis to help a context-sensitive implementation of the interventions recommended by the World Health Organization to optimize cesarean section use. Trial registration IS002316 Cesarean section is an essential medical tool for mothers and their children, but nowadays its overuse is a problem worldwide. Our purpose is to get information from hospitals, health professionals and women about how cesarean section is used in Argentina. In this protocol we describe how we will carry out the study and the characteristics of the hospitals and participants. We will implement this study in seven provinces of Argentina, in hospitals that have more than 1,000 births each year, had a cesarean section rate higher than 27% in 2016 and use the Perinatal Information System. We will gather information using forms, surveys and interviews. We want to identify the factors that decide the use of a cesarean section, the potential interventions that can improve the use of cesarean section and, in the case of women, the type of delivery they prefer. We expect that this study will give us a diagnosis of how cesarean section is used in Argentina, and that this will help to apply the interventions that the World Health Organization recommends to optimize the use of cesarean section in our specific context.

En paralelo a la pandemia por el nuevo coronavirus (SARS-CoV-2) que causa la enfermedad por coronavirus (COVID-19), emerge otra epidemia denominada infodemia. Esto provoca una saturación y sobreexposición a información de calidad variable y dificulta el acceso a la información confiable por el personal de salud y otros tomadores de decisión. A su vez, existen diversas formas de síntesis de información; entre las más conocidas se encuentran las revisiones sistemáticas, que pueden asistir a los tomadores de decisiones en la formulación de políticas y cuidados basados en la evidencia. En este artículo, se resumen algunas de las limitaciones en las revisiones sistemáticas actuales y los retos que acarrean las nuevas metodologías para la síntesis de la evidencia. Cochrane y otras organizaciones han liderado la innovación metodológica para favorecer el acceso y uso de la síntesis de información en COVID-19. Aparecen en escena las revisiones sistemáticas rápidas para dar respuesta a preguntas de prioridad alta en los diferentes países, se crea un repositorio de ensayos clínicos sobre COVID-19 y se pone en marcha un protocolo a nivel internacional para conducir un metaanálisis en red vivo sobre la efectividad de las intervenciones terapéuticas y de prevención en pacientes infectados por SARS-CoV-2. A nivel regional, se destacan la base de datos COVID-19 de la Organización Panamericana de la Salud y el registro de estudios primarios y revisiones sistemáticas de libre acceso (plataforma Living OVerview of the Evidence, L·OVE).

AIM: It is of critical importance to have internationally constructed tools to address early childhood development. The aim of this second phase of a two-phase study was to examine the sensitivity and specificity of the Guide for Monitoring Child Development (GMCD) in identifying developmental delay in four diverse countries. METHODS: The first phase of this 2011-2015 back-to-back study included 4949 children up to 42 months of age from primary healthcare centres in Argentina, India, South Africa and Turkey. Distribution curves were generated to show the ages when the children attained GMCD milestones and those that could be used across sexes and countries were placed in age ranges corresponding to the 85th and 97th percentile point estimates. Phase two examined a separately recruited sample of children in those countries to determine sensitivity and specificity of the GMCD. RESULTS: The validation phase of the 85 milestones in the GMCD identified delayed development in 30% of the 1731 children in the four countries. The sensitivity and specificity ranged from 0.71-0.94 and 0.69-0.82, respectively, for the total sample and the different age groups. CONCLUSION: The GMCD standardised in four diverse countries has appropriate accuracy for identification of children with developmental delay.

Introducción: Las infecciones por Staphylococcus aureus meticilino resistente adquirido en la comunidad (SAMR-ac) son motivo de consulta frecuente en pediatría. La mayoría se presentan como infecciones de piel y partes blandas; sin embargo, en la última década, se ha constatado un aumento de las infecciones invasivas. Objetivos: El objetivo principal es describir las características clínico-epidemiológicas de las infecciones producidas por SAMR-ac. El objetivo secundario es comparar la prevalencia, presentación clínica y susceptibilidad antibiótica con un período previo de estudio (1/2004-12/2007). Material y métodos: Estudio descriptivo, prospectivo, de tipo transversal. Criterios de inclusión: niños con diagnóstico de infección por SAMR-ac admitidos en el Hospital de Niños de Rosario, período de enero de 2008 a diciembre de 2014. Criterios de exclusión: internación reciente, antibiótico o cirugía previa, comorbilidades o inmunocompromiso. Resultados: De 728 niños con infecciones por Staphylococcus aureus, 529 (73%) fueron por SAMR-ac. La tasa de incidencia de infecciones por SAMR-ac varió de 12,2/10 000 egresos hospitalarios de 2004 a 145/10 000 del 2014: 75% (391) fueron infecciones de piel y partes blandas; 8% (43), os teo articular es; 6% (30), pleuropulmonares; 5% (24), sepsis. Se observó un aumento en el número de infecciones invasivas en el 2º período sin significancia estadística (OR= 0,895; IC: 0,52-1,53). La resistencia a gentamicina, clindamicina y eritromicina se mantuvo estable en ambos períodos. Conclusión: Las infecciones por SAMR-ac fueron cada vez más frecuentes, principalmente, las de piel y partes blandas. Se observó un aumento en el número de infecciones invasivas sin significancia estadística. La resistencia antibiótica se mantuvo estable.
Introduction: Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) infections are a common reason for consultation in pediatrics. Most of them present as skin and soft tissue infections; however, invasive infections have increased during the last decade. Objectives: The main objective was to describe the clinical-epidemiological characteristics of CA-MRSA infections. The secondary objective was to compare prevalence, clinical presentation and antibiotic susceptibility with a pre-study period (1/2004-12/2007). Material and methods: This is a descriptive, prospective, cross-sectional study. Inclusion criteria: children who have been diagnosed with CA-MRSA infection and admitted to Hospital de Niños de Rosario between January 2008 and December 2014. Exclusion criteria: recent hospitalization, previous antibiotic treatment or surgery, comorbidities or immune compromise. Results: Out of 728 cases of children with Staphylococcus aureus infections, 529 (73%) were due to CA-MRSA. The incidence rate of CA-MRSA infections varied from 12.2/10 000 hospital discharges in 2004 to 145/10 000 in 2014: 75% (391) were skin and soft tissue infections; 8% (43) were osteoarticular infections; 6% (30), pleuropulmonary infections; 5% (24), sepsis. There was an increase in the number of invasive infections in the second period, with no statistical significance (OR= 0.895; CI: 0.52-1.53). Gentamicin, clindamycin and erythromycin resistance remained stable throughout both periods. Conclusion: CA-MRSA infections were increasingly more frequent, mainly skin and soft tissue infections. An increase was observed in the number of invasive infections, with no statistical significance. Antibiotic resistance remained stable.
