Maternal Anxiety and Depression and Development of Prematurely Born Infants in the First Year of Life

The Purpose of this study was: (a) to assess and to compare anxiety and depression symptoms in mothers of preterm neonates during hospitalization in the Neonatal Intenive Care Unit, after discharge, and at the end of the infants` first year of life and (b) to assess the child`s development at 12 months of chronological corrected age (CCA). Thirty-six mothers, with no psychiatric antecedents assessed with the SCID-NP were evaluated by STAI and BDI The infants were assessed with Bayley-II Scales. There was a significant decrease in clinical symptoms of state-anxiety in mothers (p =.008). comparing the period during hospitalization and after discharge of the infants. Clinical symptoms of anxiety and depression were observed in 20% of the mothers at the end of the infants` first year of age. The majority of the infants exhibited normal development on Bayley-II at 12 months CCA: however. 25% of the infants displayed cognitive problems and 40% motor problems. The mothers` anxiety and depression symptoms decreased it the end of the first year of life of the pre-term infants and the children showed predominately normal development Lit this phase.

Risk stratification in neonates and infants submitted to cardiac surgery with cardiopulmonary bypass: A multimarker approach combining inflammatory mediators, N-terminal pro-B-type natriuretic peptide and troponin I

Low cardiac output syndrome (LCOS) is a common problem following cardiac surgery with cardiopulmonary bypass (CPB) in neonates and infants, and its early recognition remains a challenging task. We aimed to test whether a multimarker approach combining inflammatory and cardiac markers provides complementary information for prediction of LCOS and death in children submitted to cardiac surgery with CPB. Forty-six children younger than 18 months with congenital heart defects were prospectively enrolled. No intervention was made. Blood samples were collected pre-operatively, during CPB and post-operatively (PO) for measurement of interleukin (IL)-6, IL-8, IL-10, tumor necrosis factor (TNF)-alpha, cardiac troponin I (cTnI) and N-terminal pro-B-type natriuretic peptide (NT-proBNP). Clinical data and outcome variables were recorded. Logistic regression was used to identify predictors of LCOS and death. Multivariate logistic regression identified pre-operative NT-proBNP and IL-8 4 h PO as independent predictors of LCOS, while cTnI 4 h PO and CPB length were independent predictors of death. The use of inflammatory and cardiac markers in combination improved sensitivity, negative predictive value and accuracy of the models. In conclusion, the combined assessment of inflammatory and cardiac biochemical markers can be useful for identifying young children at increased risk for LCOS and death after heart surgery with CPB.

Pneumococcal Nasopharyngeal Carriage Among Infants Born to Human Immunodeficiency Virus-infected Mothers Immunized With Pneumococcal Polysaccharide Vaccine During Gestation

Background: We have previously shown that 23-valent pneumococcal polysaccharide vaccine (PPV) is immunogenic in human immunodeficiency virus (HIV)-infected mothers and provides vaccine-induced antibodies to the infant. We compared the nasopharyngeal pneumococcal colonization (NPC) rates in <6-month-old infants born to HIV-infected mothers, according to immunization with PPV during pregnancy. Methods: NPC was evaluated in 45 term infants born to vaccinated women (PPV+) and in 60 infants in a control group (PPV-), at 2 months (+/- 30 days), 4 months (+/- 30 days), and 6 months (+/- 30 days) of age. Results: A total of 82 infants completed the study (at least 2 of 3 evaluations), 35 (77%) in the PPV+ and 47 (78.3%) in the PPV- groups, respectively. Infant gender, HIV infection status, number of adults, children, and smokers in the household, day-care attendance, occurrence of respiratory signs, and cotrimoxazole use were similar in both groups. NPC rates increased equally with age in both groups (2 months = 26.7% vs. 25.6%; 4 months = 34.5% vs. 38.6%; 6 months = 38.7% vs. 56.3%, in PPV+ and PPV-, respectively). After controlling for potential confounders, we found no association between maternal vaccination and infant pneumococcal carriage (adjusted odds ratio = 0.70; 95% confidence interval: 0.23, 2.21) Conclusions: Vaccination of HIV-infected mothers with PPV did not protect infants younger than 6 months of age from nasopharyngeal pneumococcal carriage.

Lower respiratory tract infections among human immunodeficiency virus-exposed, uninfected infants

Objectives: To evaluate whether maternal HIV disease severity during pregnancy is associated with an increased likelihood of lower respiratory tract infections (LRTIs) in HIV-exposed, uninfected infants. Methods: HIV-exposed, uninfected, singleton, term infants enrolled in the NISDI Perinatal Study, with birth weight >2500 g were followed from birth until 6 months of age. LRTI diagnoses, hospitalizations, and associated factors were assessed. Results: Of 547 infants, 103 (18.8%) experienced 116 episodes of LRTI (incidence = 0.84 LRTIs/100 child-weeks). Most (81%) episodes were bronchiolitis. Forty-nine (9.0%) infants were hospitalized at least once with an LRTI. There were 53 hospitalizations (45.7%) for 116 LRTI episodes. None of these infants were breastfed. The odds of LRTI in infants whose mothers had CD4% <14 at enrollment were 4.4 times those of infants whose mothers had CD4% >= 29 (p = 0.003). The odds of LRTI in infants with a CD4+ count (cells/ mm(3)) <750 at hospital discharge were 16.0 times those of infants with CD4+ >= 750 (p = 0.002). Maternal CD4+ decline and infant hemoglobin at the 6-12 week visit were associated with infant LRTIs after 6-12 weeks and before 6 months of age. Conclusions: Acute bronchiolitis is common and frequently severe among HIV-exposed, uninfected infants aged 6 months or less. Lower maternal and infant CD4+ values were associated with a higher risk of infant LRTIs. Further understanding of the immunological mechanisms of severe LRTIs is needed.
