Ante-, peri- and postnatal factors associated with intraventricular hemorrhage in very premature infants.
2017
Intraventricular hemorrhage (IVH) is one of the most serious complications in preterm infants and is associated with neurological sequelae and mortality. Over the past few decades, the rate of IVH has decreased due to improved neonatal intensive care. However, up to 15-25% of very and extremely premature infants (32 and28weeks of pregnancy (WOP) respectively) still suffer from IVH.The aim of this study was to perform an updated, multicenter analysis to identify ante-, peri, and postnatal factors other than gestational age/birth weight associated with IVH of any grade in a large cohort of very and extremely premature infants.We performed a retrospective analysis in a prospectively conducted …
Clinical approach to the analysis of causes of death in the first two years of life of very‐low‐birthweight infants in a multicentre setting
1997
Mortality in the first 2 years of 634 very-low-birthweight infants admitted to eight neonatal intensive care units in Italy, and the factors associated with the net probability of death from each cause, were studied by means of the Cox proportional hazard model. A clinical classification of the causes of death was used. Overall mortality was 33.7% (intercentre range 12.6-52.9%). The highest cause-specific mortality rates were observed for respiratory problems, intra-ventricular haemorrhage (IVH) and infections (14.5%, 6.3% and 5.7% respectively). The leading causes of death were respiratory problems and IVH in the first week of life, infections from the second week up to the end of the firs…
Urinary metabolomics of bronchopulmonary dysplasia (BPD): preliminary data at birth suggest it is a congenital disease
2014
Abstract Objective: Bronchopulmonary dysplasia (BPD) or chronic lung disease is one of the principal causes of mortality and morbidity in preterm infants. Early identification of infants at the greater risk of developing BPD may allow a targeted approach for reducing disease severity and complications. The trigger cause of the disease comprehends the impairment of the alveolar development and the increased angiogenesis. Nevertheless, the molecular pathways characterizing the disease are still unclear. Therefore, the use of the metabolomics technique, due to the capability of identifying instantaneous metabolic perturbation, might help to recognize metabolic patterns associated with the cond…
First-year blood pressure increase steepest in low birthweight newborns.
2006
The present research has been undertaken prospectively to study the impact of birthweight and growth pattern on blood pressure changes from birth through the first year of life.Parents of newborns born at term (gestational age37 weeks) after uncomplicated pregnancies and in the absence of perinatal illness were randomly invited to allow their children to participate in the study. One hundred and forty-nine (84 male and 65 female) newborns were included in the present analysis. The newborns were divided into four groups according to birthweight:2500 g (n = 23); 2500-2999 g (n = 39); 3000-3500 g (n = 48); and3500 g (n = 39).At birth systolic and diastolic blood pressure were significantly low…
Effect of a surveillance system for decreasing neonatal nosocomial infections.
2018
Nosocomial infection in very low birthweight (VLBW) infants is a common complication with high morbimortality. New strategies to reduce its occurrence have recently led to the development of neonatal surveillance programs.To determine whether the NeoKissEs surveillance system implementation in our neonatal unit has been associated with a decrease in nosocomial infection in VLBW infants, as well as a reduction in the use of antibiotics and central venous catheters (CVC).Retrospective and descriptive study of infants1500 g admitted between January 2011 and December 2017. Rates of use of antibiotics and CVC were calculated, as well as late-onset sepsis incidence. Data were compared before and …
Audiologic profile of infants at risk: experience of a Western Sicily tertiary care centre.
2012
Objective: To identify the incidence of sensorineural hearing loss (SNHL) on infant at risk and to classify the degree and type of hearing loss describing the main causes associated in Western Sicily. To compare single TEOAE and combined TEOAE/ABR techniques studying the referral rate, the false-positive and false-negative rates through concordance test (κ coefficient), sensitivity (TPR) and specificity (TNR) for each protocol. Methods: From January 2010 to June 2011, 412 infants at risk, ranging from 4 to 20 weeks of life, transferred to Audiology Department of Palermo from the births centers of Western Sicily, underwent to audiological assessment with TEOAE, tympanometry and ABR. The foll…
Birth Weight Influences Blood Pressure Values and Variability in Children and Adolescents
2001
The objective of the present study was to assess the relationships between birth weight and the values and variability of ambulatory blood pressure. Six hundred thirty healthy children (369 girls) age 4 to 18 years (mean, 9.9 years) born at term after a normotensive pregnancy were included. The subjects were divided into 5 groups according to birth weight. For each subject, a 24-hour ambulatory blood pressure monitoring was performed according to the protocol designed. Average and variability (estimated as the standard deviation) of ambulatory blood pressure and heart rate were calculated separately for 24-hour, daytime, and nighttime periods. When values were adjusted for gender, current …
Prenatal and neonatal risk factors for the development of enamel defects in low birth weight children
2009
Oral Diseases (2010) 16, 257–262 Objective: To analyse the influence of several prenatal and neonatal risk factors in the development of enamel defects in low birth weight children. Subjects and methods: Children between 4 and 5 years of age (n = 102) were classified into: Group 1) 52 low birth weight (<2500 g); Group 2) 50 normal birth weight (≥2500 g). Medical history, prenatal and neonatal variables were collected. Enamel defects were evaluated with the modified Developmental Defects of Enamel Index. Results: The prevalence of hypoplasia and average number of affected teeth were significantly higher in group 1 than in group 2 (59.6%vs 16% and 1.6 vs 0.3 respectively). Low gestational …
Influence of Concurrent Obesity and Low Birth Weight on Blood Pressure Phenotype in Youth
2009
The aim of this study was to assess the impact of obesity and low birth weight on both office and ambulatory blood pressure (BP) values, as well as on aortic-derived parameters in youths. A total of 422 white youths, from 10 to 18 years of age, were included. Subjects were divided into 4 groups according to the presence (234; 55%) or the absence (188; 45%) of obesity and according to low (114; 27%) or normal (308; 73%, birth weight. Spacelabs 90207 was used to measure ambulatory BP during a 24-hour period. SphygmoCor radial/aortic transform software was used to estimate aortic pressure waveform. Office, 24-hour, daytime, and nighttime systolic BP values were significantly higher in those s…
