Introduction: Gastric acidity plays an important role in the protection of infants against various pathogens from the environment. The histamine-2 receptor blockers (H2-blockers) are off-labeled drugs that are frequently prescribed in preterm neonates to prevent stress ulcers. The impact of the H2-blockers on the development of the necrotizing enterocolitis (NEC) in preterm infants is still controversial, particularly in the developing world. Materials and Methods: One hundred twenty-two preterm infants were enrolled in the study. The multivariate logistic regression model was used to identify potential postnatal risk factors associated with NEC. Results: Preterm infants (n = 51) with total NEC, medical NEC, and surgical NEC had the highest rate of receiving ranitidine compared with controls (n = 71) (39.2%, 19.6%, and 47.6%, p < 0.05). Logistic regression analysis revealed that ranitidine use and nosocomial infections were significantly associated with NEC development (odds ratios 1.55 and 3.3). Conclusions: We confirm that ranitidine administration was associated with an increased risk of NEC in preterm infants. H2-blockers use should be only administered in very strictly selected cases after careful consideration of the risk-benefit ratio.

Serum albumin levels have been associated with prognosis in several conditions among older adults. The aim of this study is to assess the prognostic value in mortality of serum albumin in older adults with SARS-CoV-2 infection. Methods. Cohort observational study with consecutive older-adults (≥65 years old), with confirmed SARS-CoV-2 infection admitted to a university hospital between March–May 2020. A logistic regression model was fitted to assess the impact of albumin levels on in-hospital mortality adjusted by potential confounders. Results. Among a total of 840 patients admitted to the hospital, 405 (48%) were older adults with a total of 92 deaths (23%) among them. Those who died were older, had more comorbidities, higher inflammation status and lower levels of serum albumin at admission [3.10 g/dL (0.51) vs. 3.45 g/dL (0.45); p < 0.01. Serum albumin levels at admission were negatively correlated with inflammatory markers such as C-Reactive protein (Pearson Coeff −0.4634; p < 0.001) or IL-6 (Pearson’s Coeff −0.244; p = 0.006) at admission but also to other clinical outcomes such time to clinical stability (Pearson’s Coeff −0.259; p < 0.001). Severe hypoalbuminemia associated with increased risk of mortality was defined as ≤3 g/dL at admission according to the AUC/ROC analysis (0.72 95% CI 0.63–0.81) In a multivariate logistic regression model adjusting by age, inflammation, comorbidities and severity at admission severe hypoalbuminemia was a strong predictor of in-hospital mortality (OR 2.18 95% CI 1.03–4.62; p = 0.039). Conclusion. Severe hypoalbuminemia with ≤3 g/dL is an independent risk factor for mortality among older adults with SARS-CoV-2 infection. There is a consistent correlation between albumin levels and inflammatory biomarkers. Further studies are needed to determine whether the supplementation of albumin as coadjuvant treatment will have a positive impact on the prognosis of this infection.

Objective Although the morbidity associated with red blood cell transfusion in cardiac surgery has been well described, the impacts of platelet transfusion are less clearly understood. Given the conflicting results of prior studies, we sought to investigate the impact of platelet transfusion on outcomes after cardiac surgery across institutions in Maryland. Methods Using a multiinstitutional statewide database created by the Maryland Cardiac Surgery Quality Initiative, we retrospectively analyzed data from 10,478 patients undergoing isolated coronary artery bypass across 10 centers. Platelet transfusion practices were compared between institutions. Multivariate logistic regression model was used to analyze the association between platelet transfusion and 30-day mortality and postoperative complications. Results Rates of platelet transfusion varied between institutions from 4.4% to 24.7% ( P < 0.001), a difference that remained statistically significant in propensity score–matched cohorts. Among patients on preoperative antiplatelet therapy, transfusion rates varied from 8.5% to 46.4% ( P < 0.001). There was no statistically significant relationship between case volume and transfusion rates ( P = 0.815). In multivariate logistic regression, platelet transfusion was associated with increased risk of 30-day mortality (OR 2.43, P = 0.008), postoperative pneumonia (OR 2.21, P = 0.004), prolonged intubation (OR 2.05, P < 0.001), and readmission (OR 1.43, P = 0.039). Conclusions Significant variation existed in platelet transfusion rates between institutions, even after controlling for various risk factors. This variation may be associated with increased mortality and length of stay. Further study is warranted to better understand risks associated with platelet transfusion. Standardizing practice may help reduce risk and conserve resources.

Hyperosmolar Solutions

<b><i>Introduction:</i></b> Necrotizing enterocolitis (NEC) is a disease predominantly affecting preterm infants. The administration of hyperosmolar solutions could lead to the development of NEC. The objective of this study was to measure the osmolality of enteral medications used in clinical practice and to assess the risk of NEC following exposure to hyperosmolar medications. <b><i>Methods:</i></b> A retrospective cohort study in extremely preterm infants (gestational age &#x3c;28 weeks) born between 2010 and 2016 at a tertiary neonatal intensive care unit in Sweden. 465 infants were identified via the Swedish Neonatal Quality register. Data relating to enteral administrations received during a two-week period were collected from the medical records. The osmolalities of medications were measured using an osmometer. Logistic regression was used to calculate the odds ratio of developing NEC. <b><i>Results:</i></b> A total of 253 patients met the inclusion criteria. The osmolalities of 5 commonly used medications significantly exceeded the recommended limit of 450 mOsm/kg set by the American Academy of Paediatrics (AAP). Most patients (94%) received at least one hyperosmolar medication. No significant risk of developing NEC could be found. <b><i>Conclusion:</i></b> The medications used in clinical practice can significantly exceed the limit set by the AAP. This study does not indicate an increased risk of developing NEC in extremely preterm infants following exposure to hyperosmolar medications. Further studies in larger cohorts are needed to determine the specific cut-off level of osmolality in relation to the pathogenesis of NEC.

Abstract Background After the implementation of the universal two-child policy in China, the increase in parity has led to an increase in adverse pregnancy outcomes. The impact of one and two fetuses on the incidence of fetal macrosomia has not been fully confirmed in China. This study aimed to explore the differences in the incidence of fetal macrosomia in first and second pregnancies in Western China after the implementation of the universal two-child policy. Methods A total of 1598 pregnant women from three hospitals were investigated by means of a cross-sectional study from August 2017 to January 2018. Participants were recruited by convenience and divided into first and second pregnancy groups. These groups included 1094 primiparas and 504 women giving birth to their second child. Univariate and multivariate logistic regression analyses were performed to discuss the differences in the incidence of fetal macrosomia in first and second pregnancies. Results No significant difference was found in the incidence of macrosomia in the first pregnancy group (7.2%) and the second pregnancy group (7.1%). In the second-time pregnant mothers, no significant association was found between the macrosomia of the second child (5.5%) and that of the first child (4.7%). The multivariate logistic regression model showed that mothers older than 30 years are not likely to give birth to children with macrosomia (odds ratio (OR) 0.6, 95% confidence interval (CI) 0.4,0.9). Conclusions The incidence of macrosomia in Western China is might not be affected by the birth of the second child and is not increased by low parity.

Abstract Low birth weight (LBW) is associated with increased risk of cardiovascular diseases at adulthood. Nevertheless, the impact of LBW on the endothelium is not clearly established. We investigate whether LBW alters the angiogenic properties of cord blood endothelial colony forming cells (LBW-ECFCs) in 25 preterm neonates compared with 25 term neonates (CT-ECFCs). We observed that LBW decreased the number of colonies formed by ECFCs and delayed the time of appearance of their clonal progeny. LBW dramatically reduced LBW-ECFC capacity to form sprouts and tubes, to migrate and to proliferate in vitro. The angiogenic defect of LBW-ECFCs was confirmed in vivo by their inability to form robust capillary networks in Matrigel plugs injected in nu/nu mice. Gene profile analysis of LBW-ECFCs demonstrated an increased expression of antiangiogenic genes. Among them, thrombospondin 1 (THBS1) was highly expressed at RNA and protein levels in LBW-ECFCs. Silencing THBS1 restored the angiogenic properties of LBW-ECFCs by increasing AKT phosphorylation. The imbalance toward an angiostatic state provide a mechanistic link between LBW and the impaired angiogenic properties of ECFCs and allows the identification of THBS1 as a novel player in LBW-ECFC defect, opening new perspectives for novel deprogramming agents.

Background. In low-income countries, preterm nutrition is often inadequately addressed. The aim of the study was to assess the patterns of feeding and associated clinical outcomes of preterm neonates admitted to neonatal intensive care units in Ethiopia. Method. This was a multicenter, prospective study. Infants’ clinical characteristics at birth, daily monitoring of feeding history, and weight measurements were collected. An outcome assessment was completed at 28 days. Result. For this analysis, 2560 infants (53% male) were eligible. The mean (SD) gestational age was 33.1 (2.2) weeks. During the hospital stay the proportion of infants on breast milk only, preterm formula, term formula, and mixed feeding was 58%, 27.4%, 1.6%, and 34.1%, respectively. Delay in enteral feeding was associated with increased risk of death (odds ratio [OR] = 1.92, 95% confidence interval [CI] = 1.33-2.78; P < .001) and (OR = 5.06, 95% CI = 3.23-7.87; P < .001) for 1 to 3 and 4 to 6 days of delay in enteral feeding, respectively, after adjusting for possible confounders. The length of delay in enteral feeding was associated with increased risk of hypoglycemia (OR = 1.2, 95% CI = 1.1-1.2; P = .005). The mortality rate was lower in hospitals providing preterm formula more often ( P = .04). Half of the infants continued losing weight at the time of discharge. Conclusion. Delayed enteral feeding significantly increases the risk of mortality before discharge and hypoglycemia in preterm infants in resource-limited settings. Ensuring adequate nutritional support of preterm infants is highly needed.

Background There have been recent concerns regarding the higher rates of spontaneous intestinal perforation (SIP) in preterm infants that have been exposed to intrapartum magnesium sulfate (MgSO4). Objective To assess the association between intrapartum MgSO4 exposure and necrotizing enterocolitis (NEC) and/or SIP in extremely preterm neonates. Design A retrospective cohort study was conducted using data from the Canadian Neonatal Network database. Infants born at < 28 weeks' gestation admitted to neonatal units in Canada between 2011 and 2014 were divided into two groups: those exposed antenatally to MgSO4 and those unexposed. Stratified analyses for infants born between 22 and 25 weeks' gestation and those born between 26 and 27 weeks' gestation were conducted. The primary outcome was intestinal injury, identified as either NEC or SIP. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were calculated using multivariable logistic regression. Results We compared 2,300 unexposed infants with 2,055 exposed infants. There was no difference in the odds of NEC (9.88% exposed vs. 9.59% unexposed; aOR: 0.92; 95% CI: 0.75–1.14) or SIP (3.4% exposed vs. 3.39% unexposed; aOR: 1.05; 95% CI: 0.75–1.48) between the two groups. Conclusion Antenatal exposure to MgSO4 was not associated with NEC or SIP in extremely preterm infants.

Introduction. Children born prematurely have an increased risk of immediate medical complications, as well as socioemotional, cognitive, linguistic and sensory processing disorders later in life. Studies have examined the effects of prematurity on developmental outcomes, such as cognition, however, there is a need for a more detailed examination of sensory processing disorders in preterm infants. Not only is prenatal neurosensory development interrupted in utero, but these children may also experience intense stimulation in the neonatal unit, which can further alter the development and function of the sensory system. Objective. The paper presents an overview of research on sensory processing disorders in premature infants, with special emphasis on the impact of the environment of the neonatal unit. Method. Insight into the relevant literature was performed by specialized search engines on the Internet and insight into the electronic database. Results. Sensory processing disorders affect 39% to 52% of newborns born prematurely, with some evidence to suggest that children born before 32 weeks are most at risk. The literature to date has consistently reported difficulties in sensory modulation of preterm infants, within the tactile, vestibular, auditory, oral, and visual domains. Conclusion. Sensory processing disorders in preterm infants appear to occur as a result of their immature neurological and biological system and being in the environment of a neonatal intensive care unit, which is unable to meet the sensory needs of preterm infants. Altered sensory experiences, during periods of neurodevelopmental vulnerability and fragility, can result in sensory processing disorders, which may include enhanced responses or less response to stimuli (hyper or hyposensitivity).

Abstract Preterm neonates with antenatal doppler abnormalities are at increased risk of necrotizing enterocolitis (NEC). In these neonates, we did a meta-analysis to compare the impact of early versus late initiation of feeding, and slow versus rapid feed advancement on the important neonatal outcomes. The databases of PubMed, Embase, Cochrane central, CINAHL and google scholar were searched on 6th September 2020. We included all randomized controlled trials addressing the study objective(s). The risk of bias was assessed using the Risk of Bias tool, version 2. Certainty of evidence was assessed using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach. Early feeding did not increase the incidence of NEC stage 2 or more (odds ratio/OR 1.27, 95% confidence interval/CI 0.83, 1.96; 6 studies, 772 participants) and mortality (OR 0.79, 95% CI 0.4, 1.57; 3 studies, 498 participants). A trend was noted towards an increased incidence of feeding intolerance (OR 1.37, 95% CI 0.98, 1.92). There was a significant reduction in time to reach full feeds, duration of total parental nutrition, duration of hospital stay, and rates of hospital-acquired infections. The time to regain birth weight was not different. Rapid feed advancement decreased the time to reach full feeds, without affecting other outcomes. The overall certainty of the evidence was rated low. Heterogeneity was not significant. Conclusion: There is low-certainty evidence to recommend early feed initiation in preterm neonates with antenatal doppler abnormalities. The data is insufficient to make a recommendation on the rapidity of feed advancement.
