Clinical predictors for surfactant retreatment in preterm infants with respiratory distress syndrome: the results of a pooled analysis.

Background: The issue of retreatment with surfactant of infants with respiratory distress syndrome (RDS) has been poorly investigated. Our aim was to identify possible clinical predictors of the need for multiple doses of surfactant in a large cohort of very preterm infants.

Methods: Data were analyzed from three previous studies on infants born between 25 and 31 weeks of gestation with RDS who were treated with surfactant.

Resuscitation With Placental Circulation Intact Compared With Cord Milking: A Randomized Clinical Trial.

Importance: Among preterm newborns undergoing resuscitation, delayed cord clamping for 60 seconds is associated with reduced mortality compared with early clamping. However, the effects of longer durations of cord clamping with respiratory support are unknown.

Objective: To determine whether resuscitating preterm newborns while keeping the placental circulation intact and clamping the cord after a long delay would improve outcomes compared with umbilical cord milking.

The B-cells paradigm in Systemic Sclerosis: an update on pathophysiology and B-cell targeted therapies.

Systemic sclerosis is considered a rare autoimmune disease in which there are alterations of both the innate and adaptive immune response resulting in the production of autoantibodies. Abnormalities of the immune system compromise the normal function of blood vessels leading to a vasculopathy manifested by Raynaud's phenomenon, an early sign of systemic sclerosis. As a consequence of this reactive picture, the disease can evolve leading to tissue fibrosis.

Splanchnic and cerebral oxygenation during cyclic phototherapy in preterm infants with hyperbilirubinemia.

Cyclic phototherapy (cPT) can achieve a reduction in total serum bilirubin comparable to that achieved with standard continuous PT in preterm infants. Our aim was to assess the effect of cPT on splanchnic (rSOS) and cerebral (rSOC) oxygenation measured by near-infrared spectroscopy (NIRS). We prospectively studied 16 infants with a gestational age of 25-34 weeks with hyperbilirubinemia requiring PT.

Direct breastfeeding: Predictive factors and possible effects on neurodevelopment in very preterm infants.

Background: the importance of sucking milk directly at the mother's breast is often underestimated and many aspects of direct breastfeeding of very preterm infants are not investigated.

Aim: The primary endpoint of the study was to identify maternal and infant clinical predictors of direct breastfeeding in a cohort of infants born at <32 weeks of gestation or weighing <1500 g. The secondary endpoint was to evaluate the possible effects of direct breastfeeding on infant neurodevelopment.

HPLC and flow cytometry combined approach for HbF analysis in fetomaternal haemorrhage evaluation.

Introduction: Recently, a flow cytometric (FC) based test has been developed for detection of circulating fetal cells to replace the less accurate and reproducible Kleihauer-Betke test.FC test is easier to perform, it can distinguish the origin of fetal cells, but it is expensive and available in highly specialized laboratories. We evaluated the introduction of high-performance liquid chromatography (HPLC) approach as initial screening to identify patients who need an additional FC test to better discriminate the nature of haemoglobin-F (HbF) positive cells.

A structured programme to promote breastfeeding improved the rates in very preterm infants at discharge.

Aim: We developed the Promotion of Breastfeeding (PROBREAST) programme and evaluated what effect it had on the breastfeeding rate in infants born at less than 32 weeks of gestation or weighing ≤1500 grams.

Methods: We compared the breastfeeding rate in two cohorts of patients who were born before (n = 72; January 2017 to June 2018) and after (n = 80; July 2018 to December 2019) the application of the programme. Moreover, we compared the correlation between type of feeding at discharge and post-discharge breastfeeding rate, between exclusive breastfeeding, postnatal growth and neurodevelopment.

Leveraging SARS-CoV-2 Main Protease (M) for COVID-19 Mitigation with Selenium-Based Inhibitors.

The implementation of innovative approaches is crucial in an ongoing endeavor to mitigate the impact of COVID-19 pandemic. The present study examines the strategic application of the SARS-CoV-2 Main Protease (M) as a prospective instrument in the repertoire to combat the virus.

A Simulation Competition on Neonatal Resuscitation as a New Educational Tool for Pediatric Residents.

Background: Training programs on resuscitation have been developed using simulation-based learning to build skills, strengthen cognitive strategies, and improve team performance. This is especially important for residency programs where reduced working hours and high numbers of residents can reduce the educational opportunities during the residency, with lower exposure to practical procedures and prolonged length of training. Within this context, gamification has gained popularity in teaching and learning activities.

Carboxyhemoglobin as biomarker of late-onset sepsis in preterm infants.

Carboxyhemoglobin (COHb) is considered a biomarker of oxidative stress and previous studies reported an increase in COHb levels in preterm infants who develop late-onset sepsis (LOS). Our aim was to assess the correlation between COHb levels and the risk for LOS development. We retrospectively studied 100 preterm infants, 50 in the LOS and 50 in the no LOS group.

Neonatal Outcomes of Term Infants Born with Meconium-Stained Amniotic Fluid.

Meconium-stained amniotic fluid (MSAF) is considered an alarming sign of possible fetal compromise and it has recently been reported that neonatal outcome correlates with the degree of meconium thickness. We retrospectively studied 400 term infants allocated in clear amniotic fluid and grade 1, 2, and 3 MSAF groups on the basis of color and thickness of AF. Multivariable logistic regression analysis was performed to evaluate the potential independent effect of delivery with MSAF of different severity on the risk of a composite adverse neonatal outcome.

Cardiac Hypertrophy Associated with Insulin Therapy in Extremely Preterm Infants.

Background: In the neonatal period, cardiac hypertrophy (CH) has been commonly associated with hyperinsulinemic pathologies, and the first case of CH in an extremely preterm infant treated with insulin infusion has recently been reported. To confirm this association, we report a case series of patients who developed CH after insulin therapy.

Methods: Infants with gestational age < 30 weeks and birth weight < 1500 g, born from November 2017 to June 2022, were studied if they developed hyperglycemia requiring treatment with insulin and had echocardiographic diagnosis of CH.

Carboxyhemoglobin as biomarker of prematurity complications.

Background: Carboxyhemoglobin (COHb) is considered a biomarker of oxidative stress and previous studies suggest a correlation between its blood level and prematurity complications. Our aim in this study was to assess the correlation between COHb levels and the risk for bronchopulmonary dysplasia (BPD), intraventricular hemorrhage (IVH), and retinopathy of prematurity (ROP).

Methods: We retrospectively studied 178 preterm infants with gestational age of 27.

Skin IL-17A and IFN-γ Production Correlate with Disease Severity in Patients with Psoriasis and Streptococcal Infection.

Psoriasis is a multisystemic inflammatory disorder mainly involving the skin and joints, whose etiopathogenesis is still not completely understood. An association with streptococcal throat infection has been suggested. We aim to investigate a correlation between IL-17A and IFN-γ production by T cells infiltrating skin lesions and PASI in 313 patients with psoriasis, compared with that in 252 healthy controls.

Adipocytokine plasma level changes in a 24-month dietary and physical activity randomised intervention trial in postmenopausal women.

Background: Adipocytokines are signaling molecules secreted by adipose tissue contributing to the control of body fat, energy expenditure and secretion of insulin and cytokines. They have been related to the development of obesity, type-2 diabetes, cardiovascular diseases and cancer. Diet and physical activity (PA) may have beneficial effects on their level.

Preliminary results indicate that regular training induces high protection against oxidative stress in basketball players compared to soccer.

In elite athlete several metabolic changes occur during regular training. These modifications are associated with changes in blood metabolic profile and can lead to adaptive mechanisms aimed at establish a new dynamic equilibrium, which guarantees better performance. The goal of this study was to characterize the plasma metabolic profile and redox homeostasis, in athletes practicing two different team sports such as soccer and basketball in order to identify potential metabolic pathways underlying the differences in training programs.

Effects of a 24-Week Exercise Program on Functional Fitness, Oxidative Stress, and Salivary Cortisol Levels in Elderly Subjects.

Aging is a biological and irreversible process characterized by physiological alterations resulting in a progressive decline in biological functions, decreased resistance or adaptability to stress, and increased disease susceptibility. A decline in functional fitness, imbalance between pro- and antioxidant capacity, and/or hormonal dysregulation adversely impact physical capacity, emotional status, and overall quality of life, especially within the elderly population. On the other hand, regular physical activity is considered an effective strategy to prevent and reduce those changes associated with primary aging and concurrent chronic disease, while slowing age-related physical degeneration.

Changes of Oxidative Stress-Related Gene Expression in an in vitro Model of Neonatal Hypoxic-Ischemic Encephalopathy.

Background: We recently demonstrated that oxygen-glucose deprivation (OGD) and unconjugated bilirubin (UCB) can damage mature and immature organotypic hippocampal slices and induce an oxidative stress similar to what occurs in jaundiced term and preterm infants with hypoxic-ischemic encephalopathy (HIE).

Objectives: To assess the effects of OGD and UCB on the expression of heme-oxygenase 1 (HO-1) and oxidative stress-related enzymes in an in vitro model of HIE.

Methods: Mature and immature organotypic hippocampal slices were exposed to 30-min OGD and to 24 h UCB or UCB plus human serum albumin (HSA).

Splanchnic oxygenation during phototherapy in preterm infants with hyperbilirubinemia.

Background: It has been reported that preterm infants can develop feeding intolerance during phototherapy (PT) and that PT can affect mesenteric perfusion in these patients.

Aims: Our aim was to assess if PT can decrease regional splanchnic oxygenation (rSOS) measured by near infrared spectroscopy (NIRS).

Study Design: We prospectively studied infants with gestational age of 25-34 weeks with hyperbilirubinemia requiring PT.

Gastric Th17 Cells Specific for H/K-ATPase and Serum IL-17 Signature in Gastric Autoimmunity.

Human gastric autoimmunity [autoimmune gastritis (AIG)] is characterized by inflammation of the gastric mucosa and parietal cell loss. The gastric parietal cell proton pump H/K-adenosine triphosphatase (H/K-ATPase) is the major autoantigen in AIG. Our work aimed to investigate the gastric H/K-ATPase-specific T helper 17 (Th17) responses in AIG and serum interleukin (IL)-17 cytokine subfamily in AIG patients, in healthy subjects [healthy controls (HCs)], and in patients with iron deficiency anemia (IDA) without AIG.

Elevated IL-19 Serum Levels in Patients With Pernicious Anemia and Autoimmune Gastritis.

Pernicious anemia (PA) is a megaloblastic anemia consisting of hematological, gastric and immunological alterations. The immunopathogenesis of PA is sustained by both autoantibodies (e.g.
