ABSTRACT

OBJECTIVES: Preeclampsia (PE) is a hypertensive disorder of pregnancy that can cause severe complications and adverse fetal/maternal outcomes. We aimed to estimate the annual economic impact of incorporating Elecsys® sFlt-1/PlGF PE ratio, which measures soluble fms-like tyrosine kinase-1 and placental growth factor, into routine clinical practice in Argentina to aid diagnosis of PE and hemolysis, elevated liver enzymes, and low platelets syndrome from second trimester onward in pregnancies with clinical suspicion of PE. METHODS: A decision tree was used to estimate annual economic impact on the Argentine health system as a whole, including relevant costs associated with diagnosis, follow-up, and treatment from initial presentation of clinically suspected PE to delivery. Annual costs of a standard-of-care scenario and a scenario including PE ratio (reference year 2021) were analyzed. RESULTS: The economic model estimated that using the sFlt-1/PlGF ratio would enable the overall health system to save ∼$6987 million Argentine pesos annually (95% confidence interval $12 045-$2952 million), a 39.1% reduction in costs versus standard of care, mainly due to reduced hospitalizations of women with suspected PE. The economic impact calculation estimated net annual savings of approximately $80 504 Argentine pesos per patient with suspected PE. Based on the assumed uncertainty of the parameters, the likelihood the intervention would be cost saving was 100% for the considered scenarios. CONCLUSION: Our analysis suggests that the implementation of the sFlt-1/PlGF ratio in women with suspected PE in Argentina will enable the health system to achieve significant savings, contributing to more efficient clinical management through the likely reduction of unnecessary hospitalizations, depending on assumptions. Results rest on the payers' ability to recover savings generated by the intervention.

ABSTRACT

INTRODUCCIÓN: El estado nutricional materno medido como IMC (índice de masa corporal) se asocia al crecimiento fetal, al peso del recién nacido y a la morbimortalidad feto-neonatal. El sobrepeso y la obesidad son un problema de salud pública, que involucra a más de 650 millones de adultos en el mundo. Cuando llega el embarazo, este problema se encuentra instalado y hace necesaria la atención durante el cuidado prenatal. En Argentina, el Sistema Informático Perinatal (SIP) del Centro Latinoamericano de Perinatología (CLAP) de la Organización Panamericana de la Salud (OPS)/Organización Mundial de la Salud (OMS) es el mayor registro de historias clínicas perinatales y provee información para la toma de decisiones político-sanitarias. El objetivo de este estudio fue evaluar, mediante el IMC al inicio del embarazo, el estado nutricional en mujeres embarazadas que asisten a hospitales públicos de las 24 jurisdicciones del país. MÉTODOS: Se procesaron datos antropométricos registrados en el SIP de la serie histórica 2012-2017. RESULTADOS: El 4,3% de las mujeres evidenciaron bajo IMC, hubo 56,5% de normopeso, y el sobrepeso y obesidad presentaron prevalencias de 24,4% y 14,7%, respectivamente, con variaciones regionales. Se encontró un aumento sostenido de la obesidad, del 12,2% en 2012 al 17,5% en 2017. DISCUSIÓN: La serie histórica 2012-2017 muestra claramente un aumento sostenido y estadísticamente significativo de la obesidad en mujeres que inician su embarazo. (AU)


INTRODUCTION: Pre-pregnancy nutritional status measured through BMI (body mass index) is related to fetal growth, birth weight and neonatal mortality rate. Overweight and obesity are public health problems involving more than 650 million adults worldwide. When women become pregnant, this problem needs to be addressed during prenatal controls. In Argentina, the Perinatal Information System (SIP) published by the Latin American Center for Perinatology (CLAP) of the Pan American Health Organization (PAHO)/World Health Organization (WHO) is the largest perinatal database for medical records and provides information for public policy decision-making. The purpose of this study was to evaluate, using BMI, the nutritional status at the beginning of pregnancy in women attending public hospitals in the 24 provinces of Argentina. METHODS: Anthropometric measurements from the SIP for 2012-2017were processed. RESULTS: A total of 4.3% of women had low BMI, 56.5% had a normal weight, and 24.4% and 14.7% were overweight or obese, respectively, and regional variations were observed. A sustained increase in obesity was observed, going from 12.2% in 2012 to 17.5% in 2017. DISCUSSION: The time series 2012-2017 shows a sustained and statistically significant increase in obesity among women starting pregnancy.

ABSTRACT

BACKGROUND: Hypertensive disorders are a major cause of maternal mortality. In Latin America and the Caribbean, pre-eclampsia accounts for approximately one in every four maternal deaths. The World Health Organization recommends calcium supplementation during pregnancy for the prevention and treatment of pre-eclampsia and eclampsia in locations where dietary calcium intake is low. Calcium intake in Argentina is reported to be below WHO recommended levels; however, calcium intake from supplements and water has not been fully evaluated. The objective of this study was to evaluate calcium intake from supplements and water in a group of pregnant women. METHODS: This cross-sectional study was conducted at a maternity hospital in the city of Buenos Aires, Argentina. Questionnaires were verbally administered to women attending a routine antenatal care visit. Participants were 18 years of age or older and in their third trimester of pregnancy. Participants were first interviewed to evaluate nutritional supplement consumption and a subgroup was invited to undergo a 24-hour dietary recall. RESULTS: 137 women meeting inclusion criteria consented to participate. The average participant age was 27 years (SD±5.9), and all resided in an urban setting. None of the subjects took calcium supplements specifically, although 24 (17%) recalled taking supplements or antacids which contributed to their calcium intake. Mean calcium intake was 663 mg SD±389 for those women completing the 24-hour dietary recall,. This value increased to 706 mg SD±387 upon considering water intake and measuring chemical composition of water from the areas where women lived at the time of the interview and was further increased to 719 mg (SD±392) when calcium from supplements was taken into consideration. CONCLUSIONS: None of the subjects were consuming calcium supplements. Taking into account the low calcium intake in this population, diverse strategies would be required to comply with recommendations.

ABSTRACT

Peroxisome proliferator activated receptors (PPARs) are ligand activated transcription factors with crucial functions in lipid homeostasis, anti-inflammatory processes and placental development. Maternal diabetes induces a pro-inflammatory environment and alters placental development. We investigated whether PPARs regulate lipid metabolism and nitric oxide (NO) production in placental explants from healthy and type 2 diabetic (DM2) patients. We found decreased PPARα and PPARγ concentrations, no changes in PPARδ concentrations, and increased lipids, lipoperoxides and NO production in placentas from DM2 patients. PPARα agonists reduced placental concentrations of triglycerides and both PPARα and PPARδ agonists reduced concentrations of phospholipids, cholesteryl esters and cholesterol. PPARγ agonists increased lipid concentrations in placentas from DM2 patients and more markedly in placentas from healthy patients. Endogenous ligands for the three PPAR isotypes reduced NO production and lipoperoxidation in placentas from DM2 patients. We conclude that PPARs play a role in placental NO and lipid homeostasis and can regulate NO production, lipid concentrations and lipoperoxidation in placentas from DM2 patients.

ABSTRACT

Matrix metalloproteinases (MMPs) are proteolytic enzymes related to a proinflammatory environment in several diseases, including diabetes, which can be activated by reactive nitrogen species. This work aimed to determine MMP-2 and MMP-9 activities and nitration in term placentas from type 2 diabetic patients and verify the hypothesis that peroxynitrites are positive regulators of placental MMP-2 and MMP-9 activities. For this purpose, term placentas from healthy and type 2 diabetic patients were analyzed for MMP-2 and MMP-9 levels and activities, protein nitration, and nitration of MMP-2 and MMP-9. Villous explants were cultured in the presence of peroxynitrites for further evaluation of MMP-2 and MMP-9 activities. We found that MMP-2 and MMP-9 activities were increased in term placentas from diabetic patients. These changes were found even when MMP-2 protein concentrations were diminished and MMP-9 protein concentrations were not changed in the diabetic group. Increased protein nitration and specific nitration of MMP-2 and MMP-9 were found in term placentas from diabetic patients. Peroxynitrites were able to increase the activity of placental MMP-2 and MMP-9. Taken together, this study has shown for first time that peroxynitrites can nitrate and activate MMP-2 and MMP-9 in the placenta, a nitrative pathway possibly related to MMPs overactivity in the placentas from type 2 diabetic patients.

ABSTRACT

OBJECTIVE: To survey the opinion of critical care providers in Argentina about abortion. METHODS: An anonymous questionnaire was distributed to critical care providers attending the 20th National Critical Care Conference in Argentina. RESULTS: 149 of 1800 attendees completed the questionnaire, 69 (46.3%) of whom were members of the Argentine Society of Critical Care (ASCC). 122 (81.9%) supported abortion decriminalization in situations excluded from the current law; 142 (95.3%) in cases of congenital defects; 133 (89.3%) in cases of rape; 115 (77.2%) when women's mental health is at risk; 71 (47.7%) when pregnancy is unintended; and 61 (40.9%) for economic reasons. 126 (84.6%) supported abortion in public and private institutions, and 121 (81.2%) before 12 weeks of pregnancy. Variables independently associated with abortion support among female versus male attendees were abortion to preserve women's mental health (OR 4.47; 95% CI, 1.61-12.42; P=0.004) and abortion before 12 weeks of pregnancy (OR 3.93; 95% CI, 1.29-11.94; P=0.015). Abortion at request was independently associated with ASCC membership (OR 2.63; 95% CI, 1.07-6.45; P=0.034). CONCLUSION: Critical care providers would support abortion in situations excluded from the current abortion law and before 12 weeks of pregnancy, in both public and private hospitals.

ABSTRACT

ORACLE es una investigación aleatorizada factorial pragmática multicéntrica, dirigida desde la Universidad de Leicester (Reino Unido), cuyo objetivo es verificar el rol de la antibióticoterapia (eritromicina y/o augmentina y/o placebo) en la amenaza de parto prematuro (APP), con o sin rotura prematura de membranas (RPM). Los puntos finales principales son mortalidad perinatal y morbilidad neonatal severa. El tamaño muestral propuesto es de 10.000 casos. Participan 164 maternidades de 16 países y se llevan incluidos 7.364 pacientes. Argentina, que inició su gestión en agosto de 1997, a marzo de 1999 lleva incluidos 762 pacientes, reclutados entre las 9 maternidades participantes, sitas en Buenos Aires, provincia de Buenos Aires y Salta. Dos de ellas, figuran 2º y 3º en la lista de hospitales con mayor índice de reclutamiento en el mundo. El 88 por ciento de las ingresadas presentó APP y el 12 por ciento, RPM. Ambas situaciones se combinaron en el 8 por ciento de ellas. La mediana de la edad gestacional al ingreso es 32 semanas (cuartilos: 29 y 34). El 82,6 por ciento ya finalizó su participación y sólo hay un 2 por ciento de pérdidas de seguimiento. El 58 por ciento de los nacimientos ocurrió al término. La mediana de peso al nacer es 2.870 g (cuartilos 2.250 y 3.250). El 27 por ciento requirió UTI y la mortalidad perinatal es 3,6 por ciento. No se han registrado efectos adversos fetoneonatales atribuibles a las medicaciones del estudio. Los efectos adversos maternos suman 14 casos y han sido los habituales ante el consumo de antibióticos.

ABSTRACT

El objetivo del trabajo fue determinar el valor del test de fibronectina (fFN) como predictor del parto prematuro o de un período latente menor a 7 días. Se estudió una cohorte de embarazadas con amenaza del parto prematuro (APP) y membranas íntegras entre las 24 y 36 semanas de gestación (n=26) y otra con más de 36 semanas en trabajo de parto (n=12). Luego de rotar durante 10 segundos una torunda de Dacron en el moco cervical se envió al laboratorio para medir la presencia del anticuerpo monoclonal FDC-6 específico para la fFN por técnica de ELISA (Adeza Biomedical, Sunnyvale, Calif., USA). Valores por encima de 50 ng/ml se consideraron positivos. Todas las embarazadas con APP y EG al ingreso ó34 semanas recibieron tocólisis. Los resultados no fueron comunicados a los obstetras. No se observaron diferencias clínicas ni demográficas entre aquellas embarazadas que finalizaron en parto prematuro (<37 semanas de EG; n=8,21 por ciento) y las que terminaron a las 37 o más semanas (n=30,79 por ciento). La fFN se detectó en el 59 por ciento (23/39) de las muestras cervicales. Como predictor del parto prematuro el test tuvo una sensibilidad del 50 por ciento (IC 95 por ciento 35-65), especificidad del 40 por ciento (25-55), valor predictivo positivo y negativo (VPN) del 18 por ciento (6,1-30,1) y 75 por ciento (62-88) respectivamente. Sin embargo, aquellas mujeres con fFN negativa nunca finalizaron su embarazo antes de los 7 días (VPN 78,5 por ciento). En las enroladas después de las 36 semanas de gestación y que finalizaron postérmino todas (2/2) tuvieron fFN negativa. A pesar del limitado número de casos este estudio sugiere que la utilidad de la determinación de la fibronectina reside en su valor pronóstico negativo tanto del parto prematuro como de un corto período de latencia, permitiendo de esta manera evitar una hospitalización innecesaria y el uso de tocólisis, aunque esto no descarta la posibilidad futura del parto prematuro.
