Clinical and Epidemiologic Characteristics of a Cohort of HIV-Infected Mother-Infant Pairs During 21 Years.

BACKGROUND: HIV infection continues to be a worldwide public health problem. After the introduction of effective preventive measures, perinatal transmission dramatically decreased. Our aim was to assess the sociodemographic changes in pregnant women living with HIV infection and trends in perinatal transmission rates over time. SETTING: The Madrid cohort of HIV-infected mother-infant pairs is a multicenter, prospective, observational, and cohort study that collects information on HIV-infected pregnant women and their children. METHODS: Information on clinical-epidemiological characteristics of HIV-infected pregnant women until delivery and their children from 9 public hospitals was included. Data were collected from a standardized questionnaire from medical records. The results were classified in 3 periods: period 1 (P1) 2000-2006, period 2 (P2) 2007-2013, and period 3 (P3) 2014-2020. RESULTS: A total of 1521 women living with HIV and 1548 newborns were included. In P1, most mothers (75.8%) were Spanish, whereas in P2 and P3 there was a predominance of foreign origin [62.8% and 70.5% respectively ( P < 0.01)]. The percentage of women with antiretroviral treatment before pregnancy increased significantly in P3 ( P < 0.01). The proportion of Caesarean sections decreased over time ( P < 0.01): 66.2% (n = 472) in P1, 54.9% (n = 245) in P2, and 46.7% (n = 141) in P3. The percentage of preterm and low birth weight newborns showed a statistically significant decrease. Even though there were no statistically significant differences ( P = 0.154), a decrease in cases of perinatal infection was observed (1.6% in P1, 1.3% in P2 and 0.3% in P3). CONCLUSIONS: The epidemiologic characteristics of pregnant women with HIV infection have changed over time in our setting, with an increase of non-Caucasian, heterosexual, and perinatally infected mothers. Although there are still perinatal infections, especially in vulnerable populations such as immigrant women, transmission rate has markedly decreased in recent years and is still of major concern. Prevention measures should be reinforced in the most socially disadvantaged groups.

Maternal and Neonatal Prognostic Factors for Cardiorespiratory Events in Healthy Term Neonates During Early Skin-to-Skin Contact.

Background: During early skin-to-skin contact (ESSC), alterations in peripheral oxygen saturation (SpO2) and heart rate (HR) have been frequently observed. Objectives: This study aimed to determine the incidence of cardiorespiratory events (CREs) during ESSC in healthy term newborns (HTNs) and estimate the association of maternal and neonatal prognostic factors with the risk of CREs. Methods: A pooled analysis of the cohort from a clinical trial involving healthy mother-child dyads during ESSC was performed. Pulse oximetry was employed to continuously monitor SpO2 and HR within 2 h after birth. The individual and combined prognostic relevance of the demographic and clinical characteristics of dyads for the occurrence of a CRE (SpO2 <91% or HR <111 or >180 bpm) was analyzed through logistic regression models. Results: Of the 254 children assessed, 169 [66.5%; 95% confidence interval (95% CI), 60.5-72.5%] had at least one CRE. The characteristics that increased the risk of CRE were maternal age ≥35 years (odds ratio, 2.21; 95% CI, 1.19-4.09), primiparity (1.96; 1.03-3.72), gestational body mass index (BMI) >25 kg/m2 (1.92; 1.05-3.53), and birth time between 09:00 p.m. and 08:59 a.m. (2.47; 1.02-5.97). Conclusion: CREs were more frequent in HTNs born during nighttime and in HTNs born to first-time mothers, mothers ≥35 years, and mothers with a gestational BMI >25 kg/m2. These predictor variables can be determined during childbirth. Identification of neonates at higher risk of developing CREs would allow for closer surveillance during ESSC.

Baby Friendly Hospital Initiative Breastfeeding Outcomes in Mothers with COVID-19 Infection During the First Weeks of the Pandemic in Spain.

BACKGROUND: Adherence to the Ten Steps of the Baby-Friendly Hospital Initiative has been shown to have a protective role for the initiation and maintenance of breastfeeding. RESEARCH AIMS: (1) To determine the breastfeeding rate during the first 6 months of life in children of mothers diagnosed with COVID-19 infection at the time of birth; and (2) to assess the possible influence of being born in a center with Baby-Friendly Hospital Initiative accreditation. METHODS: This was a two-group comparative longitudinal observational study of infants born to mothers with COVID-19 at the time of birth, between March 13-May 31, 2020 (the first wave of the pandemic) in Spain. Fourteen Spanish hospitals participated, five (35.7%) were Baby-Friendly Hospital Initiative accredited. Type of feeding was assessed prospectively at discharge, 1, 3, and 6 months of age. A total of 248 newborns were included in the study. RESULTS: A total of 117 (47.3%) newborns were born in Baby-Friendly Hospital Initiative (BFHI) accredited centers. These centers applied skin-to-skin contact with greater probability (OR = 1.9; 95% CI [1.18, 3.29]) and separated the newborns from their mothers less frequently (OR = 0.46; 95% CI [0.26, 0.81]) than non-accredited centers. No differences were observed in relation to the presence of a companion at the time of birth. At discharge, 49.1% (n = 57) of newborns born in BFHI-accredited centers received exclusive breastfeeding versus 35.3% (n = 46) in non-accredited centers (p = .03). No differences were observed in breastfeeding rates throughout follow-up. CONCLUSIONS: The exclusive breastfeeding rate at discharge in children of mothers with COVID-19 infection at birth was higher in Baby-Friendly Hospital Initiative accredited centers, which most frequently applied skin-to-skin contact at birth as well as rooming-in.

Safety and Experience With Combined Antiretroviral Prophylaxis in Newborn at High-risk of Perinatal HIV Infection, in a Cohort of Mother Living With HIV-infant Pairs.

BACKGROUND: Perinatal transmission of HIV has dramatically decreased in high-income countries in the last few years with current rates below 1%, but it still occurs in high-risk situations, mainly pregnant women with late diagnosis of infection, poor antiretroviral adherence and a high viral load (VL). In these high-risk situations, many providers recommend combined neonatal prophylaxis (CNP). Our aim was to evaluate the safety and toxicity of CNP in infants deemed at high-risk of HIV infection among mother-infant pairs in the Madrid Cohort. MATERIALS AND METHODS: Prospective, multicenter, observational cohort study between years 2000 and 2019. The subgroup of newborns on CNP and their mothers were retrospectively selected (cohort A) and compared with those who received monotherapy with zidovudine (cohort B). Infants with monotherapy were classified according to treatment regimes in long (6 weeks) and short (4 weeks) course. RESULTS: We identified 227 newborns (33.3% preterm and 7 sets of twins) with CNP. A maternal diagnosis of HIV-1 infection was established during the current pregnancy in 72 cases (36.4%) and intrapartum or postpartum in 31 cases (15.7%). Most infants received triple combination antiretroviral therapy (65.6%; n = 149). The perinatal transmission rate in cohort A was 3.5% (95% confidence interval: 1.13%-5.92%). Infants from cohort A developed anemia (26.1% vs. 19.4%, P = 0.14) and neutropenia more frequently at 50-120 days (21.4% vs. 10.9%, P < 0.01), without significant differences in grade 3 and 4 anemia or neutropenia between the two cohorts. There were no differences in increased alanine aminotransferase. Neutropenia was more common in the long zidovudine regimes. CONCLUSIONS: Our findings provide further evidence of the safety of CNP in infants with high-risk of HIV-1 perinatal transmission.

Emerging and imported diseases diagnosed in the emergency department of a hospital in Madrid. / Enfermedades emergentes e importadas diagnosticadas en el servicio de urgencias de un hospital de Madrid.

OBJECTIVES: To describe the clinical and epidemiologic characteristics of patients diagnosed with malaria, dengue fever, and Zika or chikungunya virus infections in a hospital emergency department. To describe the usefulness of the department's diagnostic resources. MATERIAL AND METHODS: Descriptive observational study of patients diagnosed with infectious tropical diseases on the basis of samples collected in the emergency department. RESULTS: The department diagnosed 4 cases of dengue fever, 7 cases of Zika virus infection, 7 of malaria, and 2 concomitant infections (malaria plus dengue fever and malaria plus chikungunya infection). CONCLUSION: Most patients with these infections were males and natives of areas where the diseases were endemic. Even when malaria is diagnosed early, the possibility of concomitant infection by other arboviruses must be ruled out. Serology is necessary to rule out Zika virus infection; polymerase chain reaction testing of urine and serum should be included.

OBJETIVO: Describir las características clínicas y epidemiológicas de los pacientes diagnosticados de malaria, dengue, zika y chikungunya en un servicio de urgencias hospitalario (SUH), así como el valor de diagnóstico de las técnicas de las que se disponen en el SUH. METODO: . Estudio descriptivo, observacional, en el que se incluyeron pacientes diagnosticados de enfermedades infecciosas tropicales a partir de pruebas solicitadas desde un SUH. RESULTADOS: Se diagnosticaron cuatro casos de dengue, siete casos de zika, tres casos de malaria y dos casos de coinfección (malaria + dengue y malaria + chikungunya). CONCLUSIONES: . La mayoría de los pacientes valorados son varones, nativos de zonas endémicas. Aunque se realice un diagnóstico precoz de malaria, es necesario descartar coinfección por distintos arbovirus. Para estudio de virus zika, hay que solicitar una prueba de PCR en orina, además de serología y PCR en suero.

Desarrollo psicomotor en prematuros tardíos a los dos años de edad: comparación con recién nacidos a término mediante dos herramientas diferentes / Psychomotor development in late preterms at two years of age: a comparison with full-term newborn infants using two different instruments

Introducción. Los prematuros tardíos constituyen actualmente el 70% de los nacimientos prematuros. Presentan mayor comorbilidad, incluyendo las alteraciones del neurodesarrollo, que pueden no manifestarse hasta la escolarización. Objetivo. Identificar dificultades en el desarrollo neurológico a los dos años de edad. Sujetos y métodos. Se valoró el desarrollo psicomotor a los dos años de los prematuros tardíos y del grupo control a término nacidos en nuestro centro entre enero y septiembre del año 2014 mediante la escala de Brunet-Lézine revisada y el cuestionario de edades y etapas para la detección de trastornos del neurodesarrollo Ages & Stages Questionnaires (ASQ-3). Resultados. Se incluyó a 88 niños. Los prematuros tardíos presentaron puntuaciones inferiores en el lenguaje y el desarrollo postural. Las niñas obtuvieron resultados superiores en la edad de desarrollo global, la coordinación oculomotriz, el lenguaje y la sociabilidad. El cuestionario ASQ-3 detectó las diferencias en comunicación y socioindividuales. Se identificaron como factores de riesgo para presentar alteración del desarrollo la prematuridad, para alteración del lenguaje, y el sexo masculino, para menor edad de desarrollo y alteración del lenguaje. La correlación entre la valoración del lenguaje con la escala de Brunet-Lézine revisada y el cuestionario ASQ-3 fue buena, con un coeficiente de correlación de Pearson de 0,7 (p < 0,001), lo que nuestra la utilidad del cuestionario. Conclusiones. Los prematuros tardíos presentan menor desarrollo del lenguaje a los dos años. La prematuridad y el sexo masculino son factores de riesgo para presentar alteración. La valoración del lenguaje con el cuestionario ASQ-3 puede ser útil para detectar alteraciones

Introduction. Late preterm infants currently constitute 70% of preterm infant births. They present greater comorbidity, including neurodevelopment disorders, which may not manifest until the school age. Aim. To identify the existence of difficulties in the neurodevelopment at the age of two years. Subjects and methods. The psychomotor development was performed at two years of age in late preterm infants and term control group born at our center between January and September 2014, with Brunet-Lezine Revised test and Ages & Stages Questionnaires (ASQ-3) questionnaire. Results. 88 children were included. Late preterm infants had lower scores in the language area and postural developmental. Girls achieved better results than males at global developmental age, oculo-motor coordination, language area and sociability. The ASQ-3 questionnaire detected differences in communication and socio-individual. Prematurity and male sex were identified as an independent risk factor to present a developmental disorder, prematurity for language impairment and male sex for younger developmental age and language impairment. The correlation between language assessment with the Brunet-Lezine Revised test and the ASQ-3 questionnaire was good, with a Pearson correlation coefficient of 0.7 (p < 0.001), showing the usefulness of the questionnaire. Conclusions. Late preterm infants have a lower developmental age in the language area at two years. Prematurity and male sex are risk factors for developmental disorder. Language assessment with the ASQ-3 questionnaire may be a useful tool to detect disorders and intervene early
