ABSTRACT

INTRODUCTION: Prognostic markers for fetal transmission of Cytomegalovirus (CMV) infection during pregnancy are poorly understood. Maternal CMV-specific T-cell responses may help prevent fetal transmission and thus, we set out to assess whether this may be the case in pregnant women who develop a primary CMV infection. METHODS: A multicenter prospective study was carried out at 8 hospitals in Spain, from January 2017 to April 2020. Blood samples were collected from pregnant women at the time the primary CMV infection was diagnosed to assess the T-cell response. Quantitative analysis of interferon producing specific CMV-CD8+/CD4+ cells was performed by intracellular cytokine flow cytometry. RESULTS: In this study, 135 pregnant women with a suspected CMV infection were evaluated, 60 of whom had a primary CMV infection and samples available. Of these, 24 mothers transmitted the infection to the fetus and 36 did not. No association was found between the presence of specific CD4 or CD8 responses against CMV at the time maternal infection was diagnosed and the risk of fetal transmission. There was no transmission among women with an undetectable CMV viral load in blood at diagnosis. CONCLUSIONS: In this cohort of pregnant women with a primary CMV infection, no association was found between the presence of a CMV T-cell response at the time of maternal infection and the risk of intrauterine transmission. A detectable CMV viral load in the maternal blood at diagnosis of the primary maternal infection may represent a relevant biomarker associated with fetal transmission.

ABSTRACT

El absceso frío estafilocócico neonatal es una patología infecciosa localizada que ocurre en periodo neonatal con evolución benigna y de la cual hay pocas referencias en la bibliografía. Se presenta un caso para dar a conocer esta patología (AU)


Neonatal staphylococcal cold abscess refers to a local manifestation of infectious disease that occurs in the neonatal period and has favourable outcomes, on which there is currently a dearth of evidence. We present one case to contribute to the knowledge of this pathology. (AU)

ABSTRACT

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.

ABSTRACT

BACKGROUND: Our aim was to describe the clinical features of mothers with coronavirus disease 2019 (COVID-19) infection during gestation or delivery, and the potential vertical transmission. We also wish to evaluate the possible horizontal transmission after hospital discharge, by means of a follow-up of all the newborns included at 1 month of age. METHODS: This multicenter descriptive study involved 16 Spanish hospitals. We reviewed the medical records of 242 pregnant women diagnosed with COVID-19 from March 13 to May 31, 2020, when they were in their third trimester of pregnancy. They and their 248 newborn infants were monitored until the infant was 1 month old. RESULTS: Caesarean sections (C-sections) were performed on 63 (26%) women. The initial clinical symptoms were coughing (33%) and fever (29.7%). Mothers hospitalized due to COVID-19 pathology had a higher risk of ending their pregnancy via C-section (P = 0.027). Newborns whose mothers had been admitted due to their COVID-19 infection had a higher risk of premature delivery (P = 0.006). We admitted 115 (46.3%) newborn infants to the neonatal unit, of those, 87 (75.6%) were only admitted due to organizational circumstances. No infants died and no vertical or horizontal transmission was detected. Regarding type of feeding, 41.7% of the newborns received exclusive breast-feeding at discharge and 40.4% at 1 month. CONCLUSIONS: We did not detect COVID-19 transmission during delivery or throughout the first month of life in the newborns included in our study. Exclusive breast-feeding rates at discharge and at 1 month of age were lower than expected.

ABSTRACT

We report on a new patient with a 7q terminal deletion. The 18-month-old boy had metal retardation, microcephaly, a distinctive face, bilateral coloboma, café-au-lait spot on the abdomen, and sacral agenesis. The high resolution GTG bands (550-850 bands), currently used in our laboratory, showed a 7q terminal deletion, which was also confirmed with fluorescence in situ hybridization (FISH). The homeobox HLXB9 gene, localized at 7q36 has been demonstrated to be involved in sacral agenesis; in fact patients with 7q terminal deletions frequently have this malformation. We could not perform molecular studies in this patient to confirm the HLXB9 haploinsufficiency, but we postulate that he carried it.
