[Consequence of hypertensive disorders during pregnancy (THE) on women's cardiovascular health]. / Consecuencia de los trastornos hipertensivos durante el embarazo (THE) sobre la salud cardiovascular de la mujer.

Patients with hypertensive disorders of pregnancy (HDP) are at increased risk of maternal-fetal complications and represent the third leading cause of maternal mortality. To date, it is known that women experiencing this condition during pregnancy have a higher future risk of cardiovascular events (CVD). Our objective was to report the incidence of new-onset hypertension in the postpartum period. We conducted a cohort study in high-risk pregnant patients who underwent ambulatory blood pressure monitoring (ABPM) between weeks 20-30. Patients were categorized as normotensive (NT) or gestational hypertensive (GH), excluding those with chronic hypertension, and were followed until the end of pregnancy with a postpartum assessment after 3months. Patients with HDP (39%) had a higher incidence of preeclampsia and newborns with low birth weight and preterm birth. A total of 177 pregnant women were analyzed for the primary outcome. Among those with GH, 33.3% vs 17.2% of NT (P=.014) reported new-onset hypertension. The odds ratio for developing new-onset hypertension was 2.3 (95%CI: 1.20-4.77), for those with GH. In conclusion, pregnant patients with GH assessed by ABPM between 20-30weeks are at higher risk of developing new-onset hypertension in the postpartum period, emphasizing the need for closer monitoring and control to prevent future cardiovascular complications.

Medición semiautomática de la relación arteriovenosa retiniana como posible marcador de riesgo de infarto cerebral silente en pacientes hipertensos / Semi-automatic measuring of arteriovenous relation as a possible silent brain infarction risk index in hypertensive patients

PROPÓSITO: Evaluar la utilidad de un sistema semiautomático de medición de relación arteriovenosa (RAV) retiniana sobre imágenes retinográficas de pacientes hipertensos en la valoración del riesgo cardiovascular y la detección de isquemia cerebral silente (ICS). MÉTODO: Un total de 976 pacientes de la cohorte Investigating Silent Strokes in Hypertensives: a magnetic resonance imaging study (ISSYS) estudiados mediante resonancia magnética craneal para valorar la presencia o no de ICS fueron invitados a realizar una retinografía para un examen convencional de fondo de ojo y una medición semitautomática del promedio de los calibres vasculares para el cálculo de la relación arteriovenosa (RAV). RESULTADOS: Se analizaron las retinografías de 768 pacientes. Entre las lesiones observadas, solamente se encontró una asociación con la detección de ICS en aquellos pacientes con microaneurismas (OR: 2,50; IC 95%: 1,05-5,98) o una RAV alterada (<0,666) (OR: 4,22; IC 95%: 2,56-6,96). En el análisis de regresión logística multivariante ajustado por edad y sexo, solamente la RAV alterada continuó manifestándose como un factor de riesgo (OR: 3,70; IC 95%: 2,21-6,18). CONCLUSIONES: Los resultados muestran que el análisis semiautomático de la vasculatura retiniana a partir de retinografías tiene el potencial de ser considerado como un factor de riesgo vascular importante en la población hipertensa

OBJECTIVE: To evaluate the usefulness of a semiautomatic measuring system of arteriovenous relation (RAV) from retinographic images of hypertensive patients in assessing their cardiovascular risk and silent brain ischemia (ICS) detection. METHODS: Semi-automatic measurement of arterial and venous width were performed with the aid of Imedos software and conventional fundus examination from the analysis of retinal images belonging to the 976 patients integrated in the cohort Investigating Silent Strokes in Hypertensives: a magnetic resonance imaging study (ISSYS), group of hypertensive patients. All patients have been subjected to a cranial magnetic resonance imaging (RMN) to assess the presence or absence of brain silent infarct. RESULTS: Retinal images of 768 patients were studied. Among the clinical findings observed, association with ICS was only detected in patients with microaneurysms (OR 2.50; 95% CI: 1.05-5.98) or altered RAV (<0.666) (OR: 4.22; 95% CI: 2.56-6.96). In multivariate logistic regression analysis adjusted by age and sex, only altered RAV continued demonstrating as a risk factor (OR: 3.70; 95% CI: 2.21-6.18). CONCLUSIONS: The results show that the semiautomatic analysis of the retinal vasculature from retinal images has the potential to be considered as an important vascular risk factor in hypertensive population

Neurodevelopmental outcome in 2-year-old infants who were small-for-gestational age term fetuses with cerebral blood flow redistribution.

OBJECTIVE: To assess the neurodevelopmental outcome at 2 years of age of children who had been small-for-gestational-age (SGA) term babies with cerebral blood flow redistribution. METHODS: Perinatal outcome was assessed in a cohort of 97 term singleton appropriate-for-gestational-age and 125 term singleton SGA fetuses with normal umbilical artery Doppler, stratified according to the presence of cerebral blood flow redistribution. Neurodevelopmental outcome was assessed prospectively at 2 years of age by means of the 24-month Age & Stage Questionnaire (ASQ). RESULTS: Of the 125 SGA fetuses, 25 had redistribution of the cerebral blood flow, and 100 did not. There were no significant differences in perinatal outcome between these two SGA groups. At 2 years of age, children who had been SGA fetuses with middle cerebral artery (MCA) pulsatility index (PI) < 5(th) centile had a higher incidence of suboptimal neurodevelopmental outcome compared with those with normal MCA-PI (52% vs. 31%; P = 0.049) and a lower mean centile in communication (53.1 vs. 67.4; P = 0.006) and problem-solving (39.7 vs. 47.4; P = 0.04) areas. CONCLUSION: SGA fetuses with cerebral blood flow redistribution have a higher risk of subtle neurodevelopmental deficits at 2 years of age. This challenges the concept that fetal cerebral redistribution is an entirely protective mechanism and suggests MCA-PI as a risk stratifying factor for adverse neurodevelopmental outcome.

Customized birthweight standards for a Spanish population.

OBJECTIVE: To analyse the biological factors affecting birthweight and to derive customized birthweight standards for a Spanish population. METHODS: A retrospective cohort was created with all the singleton pregnancies delivered at term and free of pathology in our Institution. Birthweight was modeled by multiple linear regression from maternal (ethnic origin, maternal height, booking weight, smoking, and parity), and fetal (gender, gestational age) characteristics. RESULTS: In addition to gestational age and sex, height, booking weight, ethnic origin, parity, and smoking all have significant and independent effects on birthweight. Women from East-Asia, Morocco and South-America had newborns on average 83 g, 74 g and 95 g heavier than White-European Spanish women. The effect of smoking was found to be dose-related. CONCLUSION: We found the relative effect of the maternal and fetal characteristics to be very similar to that reported in previous studies. We report coefficients for ethnic groups that account for a sizeable proportion of the population composition of several European countries.
