Clinical evaluation of two different protein content formulas fed to full-term healthy infants: A randomized controlled trial

Background: A high early protein intake is associated with rapid postnatal weight gain and altered body composition. We aimed to evaluate the safety of a low-protein formula in healthy full-term infants. Methods: A randomized controlled trial was conducted. A total of 118 infants were randomized to receive two different protein content formulas (formula A or formula B (protein content: 1.2 vs. 1.7g/100mL, respectively)) for the first 4 months of life. Anthropometry and body composition by air displacement plethysmography were assessed at enrolment and at two and 4 months. The reference group comprised 50 healthy, exclusively breastfed, full-term infants. Results: Weight gain (g/day) throughout the study was similar between the formula groups (32.5\ub16.1 vs. 32.8\ub16.8) and in the reference group (30.4\ub15.4). The formula groups showed similar body composition but a different fat-free mass content from breastfed infants at two and 4 months. However, the formula A group showed a fat-free mass increase more similar to that of the breastfed infants. The occurrence of gastrointestinal symptoms or adverse events was similar between the formula groups. Conclusions: Feeding a low-protein content formula appears to be safe and to promote adequate growth, although determination of the long-term effect on body composition requires further study

Growth and Fat Mass in Preterm Infants Fed A Protein-Enriched Postdischarge Formula (PDF): A Randomized Controlled Trial

Background and aims: Male infants with BW< 1250 g benefit from PDF. Fetal growth seems to influence growth recovery whereas fat restoration occurs irrespective of BW. To evaluate whether being fed a PDF determines a growth benefit in two subgroups of infants. Methods: 123 preterm infants born AGA (BW=1193.4\ub1 230 g; GA=29\ub11.9 wks) and 84 born SGA (BW=1127\ub1 262g; GA=31.3\ub11.9 wks) were randomized at term corrected age (CA) in G1: 59 AGA fed PDF (2.9 g/100 kcal), G2: 64 AGA fed term formula (TF) (2.1 g/100 kcal), G3: 41 SGA fed PDF, G4: 43 SGA fed TF. From 6 months infants were fed a follow on formula and weaned according to ESPGHAN recommendations. Growth and body composition were assessed by an air displacement plethysmography system at term, 1, 3, 5, 6, 12 months. ANOVA, regression analysis. Results: G1 and G3 protein intakes were higher than those of G2 (p< 0.005) and G4(p< 0.05), respectively, whereas weight, length and fat mass were similar at each study point. G1 mean HC (cm) was bigger than that of G2 at six months (43.5\ub1 1.9 vs 42.6\ub11.6, p=0.03) whereas at 12 months no difference was found (45.4\ub11.6 vs 46\ub11.6). In AGA infants being fed a PDF formula, being male, not having a postnatal growth retardation at term correlated with bigger HC at six months [(p< 0.001), unstandardized B coefficient (SE) 0.9 (0.36); 1.2 (0.36); 1.2 (0.37), respectively]. Conclusions: Male AGA without postnatal growth retardation at term but not SGA infants appear to benefit from being fed PDF

Is nutritional support needed in late preterm infants?

Background: Late preterm birth accounts for 70 % of all preterm births. While the impact of feeding problems in very preterm infants has been widely investigated, data on late preterm infants' feeding issues are scarce. The aim of the present study was to investigate the need of nutritional support during hospital stay in a cohort of late preterm infants and to identify the factors that most contribute to its occurrence. Methods: We analyzed the medical records of late preterm infants, born 2011-2013, admitted to a single institution. Neonatal data, the need for nutritional support, defined as the need for parenteral nutrition or intravenous fluids or tube feeding, and the feeding status at discharge were retrieved. The occurrence of respiratory distress syndrome, congenital malformations/chromosomal diseases, cardiac diseases, sepsis, hypoglycemia, poor feeding and the need for surgical intervention were also collected. Results: A total of 1768 late preterm infants were included. Among the 592 infants requiring a nutritional support, 228 developed a respiratory distress syndrome, two developed a sepsis, one presented with a cardiac disease, 24 underwent a surgical intervention, eight had a chromosomal disease/congenital malformation, 80 had hypoglycemia. In addition, 100 infants required nutritional support due to poor feeding and 149 were born small for gestational age. Birth weight 642000 g (adjusted OR = 12.2, 95 % CI 7.5-19.9, p < 0.0001), gestational age of 34 weeks (adjusted OR = 4.08, 95 % CI 2.8-5.9, p < 0.0001), being small for gestational age (adjusted OR = 2.17, 95 % CI 2.8-5.9, p=0.001), having a respiratory distress syndrome (adjusted OR = 79.6, 95 % CI 47.2-134.3, p < 0.0001) and the need of surgical intervention (adjusted OR = 49.4, 95 % CI 13.9-174.5, p < 0.0001) were associated with a higher risk of need of nutritional support during hospital stay. Conclusions: Late preterm infants are at relatively high risk of requiring nutritional support during hospital stay, especially if they have a birth weight 642000 g, a gestational age of 34 weeks, are born small for gestational age, develop a respiratory distress syndrome and require a surgical intervention. The present findings add to the knowledge of late preterm infants' feeding issues and may contribute to tailoring nutritional approaches for these infants

Control and prevention measures for legionellosis in hospitals: A cross-sectional survey in Italy

Risk assessment, environmental monitoring, and the disinfection of water systems are the key elements in preventing legionellosis risk. The Italian Study Group of Hospital Hygiene of the Italian Society of Hygiene, Preventive Medicine, and Public Health and the Italian Multidisciplinary Society for the Prevention of Health Care-Associated Infections carried out a national cross-sectional survey to investigate the measures taken to prevent and control legionellosis in Italian hospitals. A multiple-choice questionnaire was developed, comprising 71 questions regarding hospital location, general characteristics, clinical and environmental surveillance, and control and preventive measures for legionellosis in 2015. Overall, 739 hospitals were enrolled from February to June 2017, and 178 anonymous questionnaires were correctly completed and evaluated (response rate: 24.1%). The survey was conducted using the SurveyMonkey (R) platform, and the data were analyzed using Stata 12 software. Of the participating hospitals, 63.2% reported at least one case of legionellosis, of which 28.2% were of proven nosocomial origin. The highest case numbers were reported in the Northern Italy, in hospitals with a pavilion structure or cooling towers, and in hospitals with higher numbers of beds, wards and operating theaters. Laboratory diagnosis was performed using urinary antigen testing alone (31.9%), both urinary antigen testing and single antibody titer (17.8%), or with seroconversion also added (21.5%). Culture-based or molecular investigations were performed in 28.8% and 22.1% of the clinical specimens, respectively. The water systems were routinely tested for Legionella in 97.4% of the hospitals, 62% of which detected a positive result (> 1000 cfu/L). Legionella pneumophila serogroup 2-15 was the most frequently isolated species (58.4%). The most common control measures were the disinfection of the water system (73.7%), mostly through thermal shock (37.4%) and chlorine dioxide (34.4%), and the replacement (69.7%) or cleaning (70.4%) of faucets and showerheads. A dedicated multidisciplinary team was present in 52.8% of the hospitals, and 73% of the hospitals performed risk assessment. Targeted training courses were organized in 36.5% of the hospitals, involving nurses (30.7%), physicians (28.8%), biologists (21.5%), technicians (26.4%), and cleaners (11%). Control and prevention measures for legionellosis are present in Italian hospitals, but some critical aspects should be improved. More appropriate risk assessment is necessary, especially in large facilities with a high number of hospitalizations. Moreover, more sensitive diagnostic tests should be used, and dedicated training courses should be implemented
