Children were relatively spared during COVID-19 pandemic. However, the recently reported hyperinflammatory syndrome with overlapping features of Kawasaki disease and toxic shock syndrome-"Paediatric Inflammatory Multisystem Syndrometemporally associated with SARS-CoV-2" (PIMS-TS) has caused concern. We describe cardiac findings and short-term outcomes in children with PIMS-TS at a tertiary children's hospital. Single-center observational study of children with PIMS-TS from 10th April to 9th May 2020. Data on ECG and echocardiogram were retrospectively analyzed along with demographics, clinical features and blood parameters. Fifteen children with median age of 8.8 (IQR 6.4-11.2) years were included, all were from African/Afro-Caribbean, South Asian, Mixed or other minority ethnic groups. All showed raised inflammatory/cardiac markers (CRP, ferritin, Troponin I, CK and pro-BNP). Transient valve regurgitation was present in 10 patients (67%). Left Ventricular ejection fraction was reduced in 12 (80%), fractional shortening in 8 (53%) with resolution in all but 2. Fourteen (93%) had coronary artery abnormalities, with normalization in 6. ECG abnormalities were present in 9 (60%) which normalized in 6 by discharge. Ten (67%) needed inotropes and/or vasopressors. None needed extracorporeal life support. Improvement in cardiac biochemical markers was closely followed by improvement in ECG/echocardiogram. All patients were discharged alive and twelve (80%) have been reviewed since. Our entire cohort with PIMS-TS had cardiac involvement and this degree of involvement is significantly more than other published series and emphasizes the need for specialist cardiac review. We believe that our multidisciplinary team approach was crucial for the good short-term outcomes.
Reduced fetal size from the first trimester is associated with increased risk for asthma and obstructed lung function in childhood. Relative change in size after the first trimester is associated with eczema.
Are maternal vitamin D and E intakes during pregnancy associated with asthma in 10-yearold children?In a longitudinal study of 1924 children born to women recruited during pregnancy, maternal vitamin D intake during pregnancy was assessed by the Food Frequency Questionnaire (FFQ) and vitamin E by FFQ and plasma α-tocopherol; respiratory questionnaires were completed for the 10-year-old children. Their treatment for asthma was also ascertained using administrative data. Longitudinal analyses included data collected at 1, 2, 5 and 10 years.Symptom data were available for 934 (49%) children and use of asthma medication for 1748 (91%). In the children maternal vitamin D intake during pregnancy was negatively associated with doctor-diagnosed asthma at 10 years of age (OR per intake quintile 0.86, 95% CI 0.74-0.99) and over the first 10 years (hazard ratio 0.90, 95% CI 0.81-1.00). Maternal plasma α-tocopherol at 11 weeks gestation was negatively associated with children receiving asthma treatment (OR per standard deviation increase 0.52, 95% CI 0.31-0.87). Maternal vitamin E intake was negatively associated with doctor-diagnosed asthma (OR 0.89, 95% CI 0.81-0.99) in the first 10 years.Low maternal vitamin D and E intakes during pregnancy are associated with increased risk of children developing asthma in the first 10 years of life. These associations may have significant public health implications. @ERSpublications Children born to women with low vitamin D and E intakes during pregnancy are more likely to develop asthma by age 10
Rationale Maternal smoking in pregnancy is associated with reduced birth weight and childhood lung function. This study determined when maternal smoking first influences fetal growth and how this relates to childhood respiratory outcomes. Methods A longitudinal cohort of 1924 pregnant women was recruited. Fetal ultrasound measurements at 11 weeks (crownerump length, CRL) and at 20 weeks gestation (femur length, FL, and biparietal diameter, BPD) and birth measurements were recorded. Childhood respiratory symptoms and spirometry were ascertained. Results Of the 1924 original study participants, fetal size was determined in 903 in the first trimester, 1544 in the second trimester and at term in 1737 infants. Maternal smoking when first pregnant was reported in 593 (31%) and was not associated with reduced CRL. There was an inverse exposure-response relationship between cigarette consumption and FL (mean reduction in lowest compared with highest tertile 0.91 cm, p¼0.033). Birth weight and length of those born to mothers who did (n¼331) and did not (n¼56) reduce cigarette consumption were similar and reduced compared with 186 infants whose mothers quit during the first trimester (p#0.020). Children of mothers who continued smoking had increased wheeze at age 2 years (OR 1.58, p¼0.017) and GP visits with wheeze at age 5 years (OR 2.18, p¼0.030) and mean reduction in forced expiratory volume in 1 s of 62 ml (p¼0.014) compared with controls. Conclusions Maternal smoking is associated with reduced fetal measurements in the second and third trimesters but not in the first trimester. Mothers who do not quit smoking during the first trimester deliver smaller infants who go on to have adverse respiratory outcomes in childhood.
Our results suggest that the nature of infant feeding during the first 6 months seems not to substantially influence the long-term risk of asthma and atopic diseases in children, nor in children at high risk of atopic disease because of a family history of atopic disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
