RESUMEN

Access to emergency obstetric care, including assisted vaginal birth and caesarean birth, is crucial for improving maternal and childbirth outcomes. However, although the proportion of births by caesarean section has increased during the last few decades, the use of assisted vaginal birth has declined. This is particularly the case in low- and middle-income countries, despite an assisted vaginal birth often being less risky than caesarean birth. We therefore conducted a three-step process to identify a research agenda necessary to increase the use of, or reintroduce, assisted vaginal birth: after conducting an evidence synthesis, which informed a consultation with technical experts who proposed an initial research agenda, we sought and incorporated the views of women's representatives of this agenda. This process has allowed us to identify a comprehensive research agenda, with topics categorized as: (i) the need to understand women's perceptions of assisted vaginal birth, and provide appropriate and reliable information; (ii) the importance of training health-care providers in clinical skills but also in respectful care, effective communication, shared decision-making and informed consent; and (iii) the barriers to and facilitators of implementation and sustainability. From women's feedback, we learned of the urgent need to recognize labour, childbirth and postpartum experiences as inherently physiological and dignified human processes, in which interventions should only be implemented if necessary. The promotion and/or reintroduction of assisted vaginal birth in low-resource settings requires governments, policy-makers and hospital administrators to support skilled health-care providers who can, in turn, respectfully support women in labour and childbirth.


L'accès aux soins obstétriques d'urgence, y compris l'accouchement vaginal assisté et la césarienne, est essentiel pour améliorer les effets de la maternité et de l'accouchement. Toutefois, bien que la proportion de césariennes ait augmenté ces dernières décennies, le recours à l'accouchement vaginal assisté a diminué. C'est particulièrement le cas dans les pays à revenu faible ou intermédiaire, bien que l'accouchement vaginal assisté soit souvent moins risqué qu'une césarienne. Nous avons donc mené un processus en trois étapes afin d'imaginer un programme de recherche qui permettrait d'augmenter le recours à l'accouchement vaginal assisté ou de le réintroduire. Après avoir réalisé une synthèse des données probantes, qui a servi de base à une consultation avec des experts techniques qui ont proposé un programme de recherche initial, nous avons sollicité et incorporé les avis des représentantes des femmes pour ce programme. Ce processus nous a permis d'imaginer un programme de recherche complet, avec des sujets classés comme suit: (i) la nécessité de comprendre la perception qu'ont les femmes de l'accouchement vaginal assisté et de fournir des informations appropriées et fiables; (ii) l'importance de la formation des prestataires de soins de santé en matière de compétences cliniques, mais aussi de respect dans les soins de santé, de communication efficace, de prise de décision partagée et de consentement éclairé; ou (iii) les obstacles à la mise en œuvre et à la durabilité et les facteurs qui les facilitent. Les réactions de femmes nous ont appris qu'il était urgent de reconnaître que l'accouchement, la naissance et le post-partum sont des processus humains intrinsèquement physiologiques et dignes au cours desquels les interventions ne devraient être mises en œuvre qu'en cas de nécessité. La promotion et/ou la réintroduction de l'accouchement vaginal assisté dans les régions à faibles ressources nécessitent que les pouvoirs publics, les décideurs politiques et les administrations d'hôpitaux soutiennent les prestataires de soins de santé qualifiés, qui pourront à leur tour soutenir respectueusement les femmes pendant l'accouchement.


El acceso a la atención obstétrica de emergencia, incluido el parto vaginal asistido y el parto por cesárea, es crucial para mejorar los resultados de la maternidad y el parto. No obstante, aunque el porcentaje de partos por cesárea ha aumentado en las últimas décadas, el uso del parto vaginal asistido ha disminuido. Esto ocurre especialmente en los países de ingresos bajos y medios, a pesar de que un parto vaginal asistido suele ser menos arriesgado que un parto por cesárea. Por lo tanto, llevamos a cabo un proceso de tres pasos para identificar un programa de investigación necesario para aumentar el uso del parto vaginal asistido o volver a incorporarlo: tras realizar una síntesis de la evidencia, que sirvió de base para una consulta con expertos técnicos que propusieron un programa de investigación inicial, buscamos e integramos las opiniones de las representantes de las mujeres sobre este programa. Este proceso nos ha permitido identificar un programa de investigación exhaustivo, con temas categorizados como: (i) la necesidad de comprender las percepciones de las mujeres sobre el parto vaginal asistido, y proporcionar información adecuada y fiable; (ii) la importancia de formar a los profesionales sanitarios en habilidades clínicas, pero también en atención respetuosa, comunicación efectiva, toma de decisiones compartida y consentimiento informado; o (iii) las barreras y los facilitadores de la implementación y la sostenibilidad. A partir de las opiniones de las mujeres, nos enteramos de la urgente necesidad de reconocer las experiencias del parto, el alumbramiento y el posparto como procesos humanos inherentemente fisiológicos y dignos, en los que las intervenciones solo deben aplicarse si son necesarias. La promoción o la reincoporación del parto vaginal asistido en regiones de escasos recursos exige que los gobiernos, los responsables de formular políticas y los administradores de hospitales apoyen a los profesionales sanitarios capacitados que, a su vez, pueden ayudar a las mujeres en el trabajo de parto y el alumbramiento de manera respetuosa.

RESUMEN

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.


RESUMEN: INTRODUCCIóN: Aun cuando la cesárea es una intervención que puede ser esencial para salvar la vida de una mujer y su hijo, el crecimiento excesivo de su uso  es un problema global. El propósito de esta investigación formativa es recolectar información sobre las instituciones, profesionales de la salud y mujeres acerca del uso de la cesárea en la Argentina. Este artículo describe la metodología del estudio, las características de los hospitales y el perfil de los participantes. METODOLOGíA: Esta investigación formativa usa un diseño mixto aplicado en siete provincias del país. Los criterios de elegibilidad para los hospitales son: (a) uso del Sistema Informático Perinatal, (b) tasa de cesáreas mayor al 27% en 2016, y (c) ≥ 1000 partos por año.

RESUMEN

Radiological findings in chest radiography and respiratory symptomatology represent a great challenge of interpretation during the COVID-19 (Coronavirus Disease 2019) pandemic, as their patterns can generate uncertainty at the time of diagnosis. This case highlights the importance in achieving an adequate correlation between diagnostic imaging and the clinical picture. We present a male adult who was admitted for 8 days of respiratory symptoms. Management with steroids was initiated according to the RECOVERY (Randomized Evaluation of COVID-19 Therapy) protocol and later confirmation of SARS-CoV-2 infection was received. In the following weeks, he deteriorated slowly and progressively clinically, without reaching respiratory failure. Imaging showed a thick-walled cavitation in the right lower lobe. Tuberculosis was suspected and confirmed. The uniqueness of this case of COVID-19 coinfection in a patient with undiagnosed tuberculosis, represents a diagnostic and clinical management challenge, where the proper interpretation of chest radiology is a fundamental tool.

RESUMEN

Hypertension is an important global public health problem. Excess sucrose during a short period near weaning (short sucrose period, SSP; sucrose during rat postnatal days 12 to 28) increases the risk of developing hypertension during adulthood and sucrose ingestion for 6 months after weaning also results in metabolic syndrome (MS) accompanied by hypertension. The aim of this study was to test if the mechanisms that lead to hypertension induced by SSP and MS are similarly modified by a resveratrol/quercetin mixture (RSV/QSC) that targets epigenetic cues. We studied the reversion of hypertension by an RSV/QSC mixture administered for 1 month (from month 6 to month 7 of age) in these two models, since it is effective against some signs of MS. RSV/QSC might determine Sirtuin 1 (SIRT1) and Sirtuin 3 (SIRT3) expression that modulates the expression of endothelial nitric oxide synthase (eNOS), which synthesizes nitric oxide (NO), and of superoxide dismutases (SOD1 and 2), which are antioxidant enzymes that have an impact on the NO levels. Short- (SSP) and long-term (MS) exposure to sucrose induced hypertension and RSV/QSC reversed it. It increased the insulin sensitivity, which may determine the eNOS expression. eNOS expression was decreased in aortas from SSP and MS rats and RSV/QSC only elevated its levels in aortas from MS rats. SIRT1 was also only increased in the MS aortas. Hypertension was accompanied by a decrease in total non-enzymatic antioxidant defenses in SSP and MS aortas, which improved with the RSV/QSC treatment. SOD1 expression was not modified by the sucrose treatments, but SOD2 expression was decreased in SSP and MS aortas. The RSV/QSC treatment increased SOD1 expression in MS aortas. SIRT3 was not modified by the sucrose or RSV/QSC treatments. In conclusion, SSP and MS lead to hypertension, but MS leads to more possible epigenetically- regulated mechanisms related to high blood pressure that could be targeted by the RSV/QSC mixture. Therefore, treatment has better effects on hypertension produced by MS.

RESUMEN

OBJECTIVE: Improve the performance of the regionalization policy in the province of Santa Fe, Argentina, as a strategy to improve perinatal health care by analyzing implementation processes and building consensus among decision makers and stakeholders around an action plan. METHODS: Implementation research was conducted using mixed methodology. A needs assessment established tracer indicators to measure adherence to the components of the policy. Actors were studied to identify the barriers and facilitators of implementation. Training was provided on the development of consensus- and evidence-based policies, through workshops in which policy briefs were prepared and through a deliberative dialogue. RESULTS: There were improvements in the number of births in appropriate hospitals and in the number of births in maternity hospitals with Essential Obstetric and Neonatal Care (CONE). Barriers were identified in the referral systems and in communication on policy, which resulted in an initial agreement on the need for guidelines and specific technical training on the transfer of babies and mothers. CONCLUSIONS: The participation of health workers in identifying barriers and strategies to overcome them, and the use of tools to report this to management, permit the adoption of consensus- and evidence-based strategies to improve policy implementation.

RESUMEN

This article presents the findings of a qualitative study exploring the experiences of women living in Buenos Aires Metropolitan Area, Argentina, with the use of misoprostol for inducing an abortion. We asked women about the range of decisions they had to make, their emotions, the physical experience, strategies they needed to use, including seeking health care advice and in dealing with a clandestine medical abortion, and their overall evaluation of the experience. An in-depth interview schedule was used. The women had either used misoprostol and sought counselling or care at a public hospital (n=24) or had used misoprostol based on the advice of a local hotline, information from the internet or from other women (n=21). Four stages in the women's experiences were identified: how the decision to terminate the pregnancy was taken, how the medication was obtained, how the tablets were used, and reflections on the outcome whether or not they sought medical advice. Safety and privacy were key in deciding to use medical abortion. Access to the medication was the main obstacle, requiring a prescription or a friendly drugstore. Correct information about the number of pills to use and dosage intervals was the least easy to obtain and caused concerns. The possibility of choosing a time of privacy and having the company of a close one was highlighted as a unique advantage of medical abortion. Efforts to improve abortion law, policy and service provision in Argentina in order to ensure the best possible conditions for use of medical abortion by women should be redoubled.

RESUMEN

BACKGROUND: In Argentina, abortion has been decriminalized under certain circumstances since the enactment of the Penal Code in 1922. Nevertheless, access to abortion under this regulatory framework has been extremely limited in spite of some recent changes. This article reports the findings of the first phase of an operations research study conducted in the Province of Santa Fe, Argentina, regarding the implementation of the local legal and safe abortion access policy. METHODS: The project combined research and training to generate a virtuous circle of knowledge production, decision-making, and the fostering of an informed healthcare policy. The project used a pre-post design of three phases: baseline, intervention, and evaluation. It was conducted in two public hospitals. An anonymous self-administered questionnaire (n = 157) and semi-structured interviews (n = 27) were applied to gather information about tacit knowledge about the regulatory framework; personal opinions regarding abortion and its decriminalization; opinions on the requirements needed to carry out legal abortions; and service's responses to women in need of an abortion. RESULTS: Firstly, a fairly high percentage of health care providers lack accurate information on current legal framework. This deficit goes side by side with a restrictive understanding of both health and rape indications. Secondly, while a great majority of health care providers support abortion under the circumstances consider in the Penal Code, most of them are reluctant towards unrestricted access to abortion. Thirdly, health care providers' willingness to perform abortions is noticeably low given that only half of them are ready to perform an abortion when a woman's life is at risk. Willingness is even lower for each of the other current legal indications. CONCLUSIONS: Findings suggest that there are important challenges for the implementation of a legal abortion policy. Results of the study call for specific strategies targeting health care providers in order to better inform about current legal abortion regulations and to sensitize them about abortion social determinants. The interpretation of the current legal framework needs to be broadened in order to reflect a comprehensive view of the health indication, and stereotypes regarding women's sexuality and abortion decisions need to be dismantled.

RESUMEN

Introduction: In 2017, Chile decriminalized abortion on three grounds: (i) if the pregnant person's life is at risk, (ii) fetal nonviability, and (iii) rape or incest. This multicase study explores the experiences of pregnant people legally entitled to but denied access to legal abortion in Chile. Methods: Through a snowball sampling approach, we recruited adult Chilean residents who sought, were eligible for, and were denied a legal abortion after September 2017. We conducted semistructured interviews with participants to explore their experiences in seeking and being denied legal abortions. We recorded and transcribed the interviews, then coded and analyzed the transcriptions to identify common themes. Results: We identified four women who met the eligibility criteria. The interviews revealed five common themes in their experiences: (i) disparate levels of social support in accessing abortion, (ii) abundant access barriers, (iii) forced pregnancy, (iv) abortion stigma, and (v) a failure of the law to provide access to abortion. Discussion and Health Equity Implications: Although the 2017 law expanded legal access to abortion in Chile, significant barriers remain. Compounded with social stigma, and the socioeconomic disparities in abortion access, pregnant people continue to face insurmountable obstacles in obtaining legal abortions, even when their lives are at risk and the pregnancy is not viable. The state must prioritize equity of access to legal abortions. Future studies should continue to explore the challenges people face accessing legal abortion care to inform strategies to ensure people are able to obtain the quality care that they are legally entitled to.

RESUMEN

INTRODUCTION: Access to comprehensive abortion care could prevent the death of between 13 865 and 38 940 women and the associated morbidity of 5 million women worldwide. There have been some important improvements in Latin America in terms of laws and policies on abortion. However, the predominant environment is still restrictive, and many women, adolescents and girls still face multiple barriers to exercise their reproductive rights. This research will systematically assess comprehensive abortion policies in five Latin American countries (Argentina, Colombia, Honduras, Mexico and Uruguay). The aim is to identify barriers, facilitators and strategies to the implementation of abortion policies, looking at four key dimensions-regulatory framework, abortion policy dynamics, abortion service delivery and health system and health outcomes indicators-to draw cross-cutting lessons learnt to improve current implementation and inform future safe abortion policy development. METHODS AND ANALYSIS: A mixed-method design will be used in the five countries to address the four dimensions through the Availability, Accessibility, Acceptability and Quality of Care model. The data collection tools include desk reviews and semi-structured interviews with key actors. Analysis will be performed using thematic analysis and stakeholder analysis. A regional synthesis exercise will be conducted to draw lessons on barriers, facilitators and the strategies. ETHICS AND DISSEMINATION: The project has been approved by the WHO Research Ethics Review Committee (ID: A66023) and by the local research ethics committees. Informed consent will be obtained from participants. Data will be treated with careful attention to protecting privacy and confidentiality. Findings from the study will be disseminated through a multipurpose strategy to target diverse audiences to foster the use of the study findings to inform the public debate agenda and policy implementation at national level. The strategy will include academic, advocacy and policy arenas and actors, including peer-reviewed publication and national and regional dissemination workshops.

RESUMEN

In December of 2020, the Argentine Congress legalized abortion through 14 weeks, vastly increasing access to abortion care in the country. The law's passage followed years of advocacy for abortion rights in Argentina - including mass public and civil society mobilization, vocal support from an established pool of abortion providers who offered abortion services under specific legal exceptions prior to the new law, and the growth of community groups such as the Socorristas en Red who provide support for people to self-manage abortions. Aided by ample political will, the number of health facilities offering services increased substantially after the law was passed, and the public visibility around the law has helped assure people seeking abortion that it is their right. Proyecto mirar is an initiative focused on both gathering and using qualitative and quantitative data to inform stakeholders about the progress and obstacles of the law's implementation. In this review, we present an overall summary of the first two years of implementation of the abortion law in Argentina based on proyecto mirar data and contextualized through the historical processes that have contributed to the law's passage and application. While we see increases in abortion services and improved public perception around abortion rights, inequities in access and quality of care persist throughout the country. Specifically, providers in some regions are well trained, while others create obstacles to access, and in some regions health services provide high quality abortion care whereas others provide substandard care. To be sure, the implementation of public policies does not happen overnight; it requires government support and backing to tackle obstacles and solve implementation problems. Our findings suggest that when new abortion laws are passed, they must be supported by civil society and government leaders to ensure that associated policies are well crafted and monitored to ensure successful implementation.

RESUMEN

Atrial natriuretic peptide (ANP) is an important regulator of blood pressure (BP). One of the mechanisms whereby ANP impacts BP is by stimulation of nitric oxide (NO) production in different tissues involved in BP control. We hypothesized that ANP-stimulated NO is impaired in the kidneys of spontaneously hypertensive rats (SHR) and this contributes to the development and/or maintenance of high levels of BP. We investigated the effects of ANP on the NO system in SHR, studying the changes in renal nitric oxide synthase (NOS) activity and expression in response to peptide infusion, the signaling pathways implicated in the signaling cascade that activates NOS, and identifying the natriuretic peptide receptors (NPR), guanylyl cyclase receptors (NPR-A and NPR-B) and/or NPR-C, and NOS isoforms involved. In vivo, SHR and Wistar-Kyoto rats (WKY) were infused with saline (0.05 ml/min) or ANP (0.2 µg·kg(-1)·min(-1)). NOS activity and endothelial (eNOS), neuronal (nNOS), and inducible (iNOS) NOS expression were measured in the renal cortex and medulla. In vitro, ANP-induced renal NOS activity was determined in the presence of iNOS and nNOS inhibitors, NPR-A/B blockers, guanine nucleotide-regulatory (G(i)) protein, and calmodulin inhibitors. Renal NOS activity was higher in SHR than in WKY. ANP increased NOS activity, but activation was lower in SHR than in WKY. ANP had no effect on expression of NOS isoforms. ANP-induced NOS activity was not modified by iNOS and nNOS inhibitors. NPR-A/B blockade blunted NOS stimulation via ANP in kidney. The renal NOS response to ANP was reduced by G(i) protein and calmodulin inhibitors. We conclude that ANP interacts with NPR-C, activating Ca-calmodulin eNOS through G(i) protein. NOS activation also involves NPR-A/B. The NOS response to ANP was diminished in kidneys of SHR. The impaired NO system response to ANP in SHR participates in the maintenance of high blood pressure.

RESUMEN

Abortion is legally restricted in most of Latin America where 95% of the 4.4 million abortions performed annually are unsafe. Medical abortion (MA) refers to the use of a drug or a combination of drugs to terminate pregnancy. Mifepristone followed by misoprostol is the most effective and recommended regime. In settings where mifepristone is not available, misoprostol alone is used.Medical abortion has radically changed abortion practices worldwide, and particularly in legally restricted contexts. In Latin America women have been using misoprostol for self-induced home abortions for over two decades.This article summarizes the findings of a literature review on women's experiences with medical abortion in Latin American countries where voluntary abortion is illegal.Women's personal experiences with medical abortion are diverse and vary according to context, age, reproductive history, social and educational level, knowledge about medical abortion, and the physical, emotional, and social circumstances linked to the pregnancy. But most importantly, experiences are determined by whether or not women have the chance to access: 1) a medically supervised abortion in a clandestine clinic or 2) complete and accurate information on medical abortion. Other key factors are access to economic resources and emotional support.Women value the safety and effectiveness of MA as well as the privacy that it allows and the possibility of having their partner, a friend or a person of their choice nearby during the process. Women perceive MA as less painful, easier, safer, more practical, less expensive, more natural and less traumatic than other abortion methods. The fact that it is self-induced and that it avoids surgery are also pointed out as advantages. Main disadvantages identified by women are that MA is painful and takes time to complete. Other negatively evaluated aspects have to do with side effects, prolonged bleeding, the possibility that it might not be effective, and the fact that some women eventually need to seek medical care at a hospital where they might be sanctioned for having an abortion and even reported to the police.

RESUMEN

In recent decades, decisive events shaping the political and social context surrounding abortion in Argentina culminated in the passing of the Voluntary Termination of Pregnancy (IVE in Spanish) Law in December 2020. The objective of this article is to explore the main barriers to accessing legal abortions in the public health system faced by women during 2019 and 2020 in two Argentine jurisdictions, Rosario and the Autonomous City of Buenos Aires. Based on an adaptation of the "three phases of delay" framework, surveys and semi-structured interviews with 117 women were conducted. Study participants reported difficulties in accessing information about the places and people to turn to for abortions, and most stated that pregnant individuals lack information regarding their legality. Although the majority of interviewees reported positive experiences with health services, they also identified some administrative and institutional barriers.


En las últimas décadas, en la Argentina sucedieron hechos determinantes en el contexto político y social con respecto al aborto, que culminaron con la aprobación de la Ley de Interrupción Voluntaria del Embarazo (IVE) en diciembre de 2020. El objetivo de este artículo es explorar las principales barreras que enfrentaron las mujeres en el acceso al aborto legal en el sistema público de salud de dos jurisdicciones de Argentina, Rosario y Ciudad Autónoma de Buenos Aires, en los años 2019 y 2020. A partir de una adaptación del modelo de las tres demoras, se realizaron encuestas y entrevistas semiestructuradas a 117 mujeres. Las participantes reportaron dificultades para acceder a información sobre lugares y personas donde recurrir para acceder un aborto. La mayoría de las participantes respondió que las personas gestantes no cuentan con información sobre la legalidad del aborto. Si bien la mayoría reportó haber tenido una buena experiencia con los servicios de salud, también identificaron algunas barreras administrativas e institucionales.

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.

RESUMEN

INTRODUCTION: Abortion-related complications are a significant cause of morbidity and mortality among women in many Latin American and Caribbean (LAC) countries. The objective of this study was to characterise abortion-related complication severity, describe the management of these complications and report women's experiences with abortion care in selected countries of the Americas region. METHODS: This is a cross-sectional study of 70 health facilities across six countries in the region. We collected data on women's characteristics including socio-demographics, obstetric history, clinical information, management procedures and using Audio Computer-Assisted Self-Interviewing (ACASI) survey the experience of abortion care. Descriptive bivariate analysis was performed for women's characteristics, management of complications and reported experiences of abortion care by severity of complications, organised in five hierarchical mutually exclusive categories based on indicators present at assessment. Generalised linear estimation models were used to assess the association between women's characteristics and severity of complications. RESULTS: We collected data on 7983 women with abortion-related complications. Complications were classified as mild (46.3%), moderate (49.5%), potentially life-threatening (3.1%), near-miss cases (1.1%) and deaths (0.2%). Being single, having a gestational age of ≥13 weeks and having expelled products of conception before arrival at the facility were significantly associated with experiencing severe maternal outcomes compared with mild complications.Management of abortion-related complications included both uterotonics and uterine evacuation for two-thirds of the women while one-third received uterine evacuation only. Surgical uterine evacuation was performed in 93.2% (7437/7983) of women, being vacuum aspiration the most common one (5007/7437, 67.4%).Of the 327 women who completed the ACASI survey, 16.5% reported having an induced abortion, 12.5% of the women stated that they were not given explanations regarding their care nor were able to ask questions during their examination and treatment with percentages increasing with the severity of morbidity. CONCLUSIONS: This is one of the first studies using a standardised methodology to measure severity of abortion-related complications and women's experiences with abortion care in LAC. Results aim to inform policies and programmes addressing sexual and reproductive rights and health in the region.

RESUMEN

The COVID-19 pandemic affected the organization of health services and had consequences for health teams, according to the pre-existing safety and working conditions. During the first week of April 2020, a cross sectional study was carried out with a qualitative-quantitative approach. The aim was to explore the conditions determining the organizational climate: leadership, communication, institutional resources, cohesion/conflict management, and training; and how these were perceived by health personnel to deal with the pandemic. A total of 5670 healthcare workers participated in an online survey and 50 were interviewed, from all subsectors of the Argentinean health system (public, private and union-health insurance); 72.9% were women, 51.4% were physicians, and the predominant age group was under 40 years. In the qualitative sample (interviews), 52% were men, 62% were physicians, and the average age was 44.8 years. The dimensions of the organizational climate were stratified and five independent predictors of perception of conditions were identified: age, gender, tasks performed, health system subsector, and jurisdiction. The condition most frequently perceived as inadequate were the inaccessibility of institutional resources and the access to personal protective equipment was a major concern. Claims included the need of institutional strategies to support healthcare workers and of a clear and uniform communication. In conclusion, at the time of the study, the health personnel perceived serious deficits in their organizations regarding the conditions necessary to confront COVID-19, with differences among subsectors of the health system.


La pandemia por COVID-19 afectó la organización de los servicios de salud y tuvo consecuencias en los equipos de salud, según las condiciones laborales y de bioseguridad pre-existentes en cada institución. Durante la primera semana de abril de 2020 se realizó un estudio de corte transversal. El objetivo fue indagar acerca de las condiciones que determinan el clima organizacional: liderazgo, comunicación, recursos institucionales, cohesión/gestión de conflictos y capacitación; y cómo éstas eran percibidas por el personal de salud para hacer frente a la pandemia. Se realizaron 5670 encuestas a trabajadores/as y 50 entrevistas a informantes clave de los tres subsectores del sistema de salud (público, privado y de seguridad social). En las encuestas, el 72.9% fueron mujeres, el 51.4% médicos/as y el grupo etario predominante fue el de menores de 40 años. El 47.8% de los/as participantes refirió pluriempleo. En las entrevistas, el 52% fueron varones, el 60% médicos/ as, la edad media 44.8 años. Se estratificaron las dimensiones y se identificaron predictores independientes de percepción: edad, género, tipo de tareas, subsector y jurisdicción. La dimensión percibida con mayor frecuencia como inadecuada fue la de recursos institucionales y la disponibilidad de equipos de protección personal fue identificada como una de las principales preocupaciones. Surgieron demandas de estrategias de contención para el personal de salud y de comunicación institucional clara y uniforme. En conclusión, al momento del estudio el personal de salud percibía serios déficits en sus organizaciones respecto de las condiciones necesarias para enfrentar la pandemia, con diferencias entre subsectores del sistema.

RESUMEN

BACKGROUND: Caesarean section rates continue to increase worldwide with uncertain medical consequences. Auditing and analysing caesarean section rates and other perinatal outcomes in a reliable and continuous manner is critical for understanding reasons caesarean section changes over time. METHODS: We analyzed data on 97,095 women delivering in 120 facilities in 8 countries, collected as part of the 2004-2005 Global Survey on Maternal and Perinatal Health in Latin America. The objective of this analysis was to test if the "10-group" or "Robson" classification could help identify which groups of women are contributing most to the high caesarean section rates in Latin America, and if it could provide information useful for health care providers in monitoring and planning effective actions to reduce these rates. RESULTS: The overall rate of caesarean section was 35.4%. Women with single cephalic pregnancy at term without previous caesarean section who entered into labour spontaneously (groups 1 and 3) represented 60% of the total obstetric population. Although women with a term singleton cephalic pregnancy with a previous caesarean section (group 5) represented only 11.4% of the obstetric population, this group was the largest contributor to the overall caesarean section rate (26.7% of all the caesarean sections). The second and third largest contributors to the overall caesarean section rate were nulliparous women with single cephalic pregnancy at term either in spontaneous labour (group 1) or induced or delivered by caesarean section before labour (group 2), which were responsible for 18.3% and 15.3% of all caesarean deliveries, respectively. CONCLUSION: The 10-group classification could be easily applied to a multicountry dataset without problems of inconsistencies or misclassification. Specific groups of women were clearly identified as the main contributors to the overall caesarean section rate. This classification could help health care providers to plan practical and effective actions targeting specific groups of women to improve maternal and perinatal care.

RESUMEN

Susceptibility to develop hypertension may be established during early stages of life that include the intrauterine period, infancy and childhood. We recently showed that blood pressure increased when rats reached adulthood when sucrose was ingested for a short-term critical window from postnatal day 12 to 28 in the rat, which corresponds to days around weaning. Here, we studied several factors that might participate in the increased susceptibility to hypertension when adulthood is reached by analyzing the changes produced at the end of the sucrose ingestion during this critical period. Body weight of the rats at the end of the sucrose period was decreased even if there was an increased ingestion in Kcal. We found an increase in blood pressure accompanied by a decrease in endothelial nitric oxide synthase (eNOS) expression in the aorta. When insulin was administered to rats receiving sucrose, glucose in plasma diminished later than in controls and this slight insulin resistance may reduce nitric oxide synthase action. Oleic acid that modulates eNOS expression was increased, lipoperoxidation was elevated and total non-enzymatic anti-oxidant capacity was decreased. There was also a decrease in SOD2 expression. We also studied the expression of Sirt1, which regulates eNOS expression and Sirt3, which regulates SOD2 expression as possible epigenetic targets of enzyme expression involved in the long- term programming of hypertension. Sirt3 was decreased but we did not find an alteration in Sirt1 expression. We conclude that these changes may underpin the epigenetic programming of increased susceptibility to develop hypertension in the adults when there was exposure to high sucrose levels near weaning in rats.

RESUMEN

Cluster-based studies involving aggregate units such as hospitals or medical practices are increasingly being used in healthcare evaluation. An important characteristic of such studies is the presence of intracluster correlation, typically quantified by the intracluster correlation coefficient (ICC). Sample size calculations for cluster-based studies need to account for the ICC, or risk underestimating the sample size required to yield the desired levels of power and significance. In this article, we present values for ICCs that were obtained from data on 97,095 pregnancies and 98,072 births taking place in a representative sample of 120 hospitals in eight Latin American countries. We present ICCs for 86 variables measured on mothers and newborns from pregnancy to the time of hospital discharge, including 'process variables' representing actual medical care received for each mother and newborn. Process variables are of primary interest in the field of implementation research. We found that overall, ICCs ranged from a minimum of 0.0003 to a maximum of 0.563 (median 0.067). For maternal and newborn outcome variables, the median ICCs were 0.011 (interquartile range 0.007-0.037) and 0.054 (interquartile range 0.013-0.075) respectively; however, for process variables, the median was 0.161 (interquartile range 0.072-0.328). Thus, we confirm previous findings that process variables tend to have higher ICCs than outcome variables. We demonstrate that ICCs generally tend to increase with higher prevalences (close to 0.5). These results can help researchers calculate the required sample size for future research studies in maternal and perinatal health.
